This embodiment is through setting up baffle 86 on blanking plate 85, avoids the PVC pipe 9 that the cutting is appearing dropping the problem that causes PVC pipe 9 to damage outside in the in-process that carries out the transmission through roller a82, makes falling into that the PVC pipe 9 that the cutting is good can be accurate connect the workbin 87 in.

Working process

Firstly, raw materials are loaded into an extruder 10 through a hopper 11, the raw materials are extruded into a prototype through the extruder 10, then the PVC pipe 9 is shaped by a cooling shaping machine 20, then the shaped PVC pipe 9 is conveyed to a slitting device 4 through a conveying belt 32, when the PVC pipe 9 is conveyed to a position between a bearing plate a53 and a bearing plate b54 and enters the position, a rodless cylinder 72 is started to enable a baffle a70 to enter the position to be buckled with the bearing plate a53 and the bearing plate b54, a motor a65 is started to drive a saw knife 61 to rotate, then a motor b is started to enable a roller a to rotate, a supporting piece 76 of the PVC pipe 9 enters the PVC pipe 9 in the conveying process, after the PVC pipe 9 is abutted against the baffle a70, the PVC pipe 9 drives the baffle a70 to enable the rodless cylinder 72 to synchronously move backwards along a chute b55, meanwhile, the baffle a70 drives the bearing plate a53 and the bearing plate b54 to respectively and move backwards along the chute a52 and a chute d69 synchronously, and a65 of the bearing plate b54 is fixedly connected with a guide rail 65 through a connecting arm 65 in the backwards moving process, the air cylinder 63 pushes the motor a65 to move downwards along the chute c58 in the process of moving backwards through the sensor, the PVC pipe 9 is cut through the saw blade 61, after the PVC pipe 9 is cut, the rodless air cylinder 72 drives the baffle a70 to move leftwards, the cut PVC pipe 9 is transferred onto the roller a82, the baffle b71 enters a station and is buckled with the bearing plate a53 and the bearing plate b54, the roller a82 transmits the cut PVC pipe 9 onto the blanking plate 85 and then falls into the material receiving box 87 below, the bearing plate a53 and the bearing plate b54 lose the push of the PVC pipe 9 move forwards under the action of the reset spring a512, the baffle b71 and the rodless air cylinder 72 are driven to move forwards, the air cylinder 63 drives the motor a65 and the saw blade 61 to move upwards and reset in the process of resetting the bearing plate b54 under the action of the sensor, when the bearing mechanism 5 and the cutting mechanism 6 are both reset, the PVC pipe 9 subsequently conveyed on the traction device 3 enters the station, at the moment, the PVC pipe 9 is over against the baffle b71, after the PVC pipe 9 abuts against the baffle b71, the PVC pipe 9 drives the baffle b71 to move backwards, meanwhile, the baffle b71 drives the bearing plate a53 and the bearing plate b54 to move backwards synchronously, the bearing plate b54 drives the motor a65 and the air cylinder 63 to move backwards in the moving backwards process, the air cylinder 63 pushes the motor a65 to move downwards in the moving backwards process so that the saw knife 61 cuts the PVC pipe 9, after the PVC pipe 9 is cut, the rodless air cylinder 72 drives the baffle b71 to move rightwards so that the cut PVC pipe 9 is transferred onto the roller a82, meanwhile, the baffle a71 enters a station to be buckled with the bearing plate a53 and the bearing plate b54, the cut PVC pipe 9 is transferred onto the blanking plate 85 through the roller a82 and then falls into the material receiving box 87 below, then the bearing mechanism 5 and the cutting mechanism 6 are reset again to carry out subsequent cutting work, and the processing operation flows are sequentially circulated.

In the description of the present invention, it is to be understood that the terms "front-back", "left-right", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the referred device or component must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the invention.

Of course, in this disclosure, those skilled in the art will understand that the terms "a" and "an" should be interpreted as "at least one" or "one or more," i.e., in one embodiment, a number of an element may be one, and in another embodiment, a number of the element may be plural, and the terms "a" and "an" should not be interpreted as limiting the number.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily made by those skilled in the art in light of the technical teaching of the present invention should be included within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
