The first upper track cylinder 22 and the second upper track cylinder 23 are started to push the upper conveying track 21 to move towards the position of the lower conveying track 31, so that the plastic profile A conveyed on the lower conveying track 31 is compressed, and the compressed plastic profile A drives the upper conveying track to rotate through friction force in the moving process.
The cutting module comprises a driving cylinder 61, a connecting plate 62, a cutting platform 71, a guide rail 73, a connecting slide block 72 and a platform bracket 74.

The actuating cylinder 62 is actuated to extend and retract the actuating rod of the actuating cylinder 61, thereby driving the cutting deck 71 to reciprocate along the deck support 74.
The cutting module further comprises a first pressing cylinder 81, a first cylinder bracket 82, a cutter fixing bracket 91, a profile cutter 92, a second cylinder bracket 83 and a second pressing cylinder 84.

The second cylinder bracket 83 is located on the right side of the cutter fixing bracket 91 and is vertically connected with the cutting platform 71, and the second pressing cylinder 84 is mounted on the second cylinder bracket 83. The contact ends of the first compression cylinder 81 and the second compression cylinder 84 with the plastic section A are respectively provided with a compression rubber block for compressing and fixing the cut plastic section A.
The synchronous operation module consists of a non-closed chain 51, a driven sprocket 52, a pawl 53, a synchronous sprocket 54, a synchronous shaft 55, a tensioning plate 56, a chain connecting plate 57 and a synchronous shaft connecting plate 58.
The synchronizing shaft connecting plate 58 is fixedly connected with the side face of the platform bracket 74 in a bonding way, one end of the synchronizing shaft 55 is vertically connected with the synchronizing shaft connecting plate 58, and the other end is connected with the synchronizing sprocket 54.
The driven sprocket 52 and the pawl 53 are both mounted at one end of the drive shaft 42, and the driven sprocket 52 is sleeved on the bearing of the drive shaft 42, the pawl 53 is connected with the bearing of the drive shaft 42, and the pawl rotates synchronously with the bearing 42. An inward gear is provided in the driven sprocket 52, and the inward gear meshes with the pawl 53 to constitute an inward-meshing ratchet mechanism. The tooth direction of the inward gear is opposite to the rotation direction of the drive shaft 42 so that the driven sprocket 52 rotates in the same direction as the pawl 53 and the driven sprocket 52 rotates at a speed greater than the pawl 53, but the reverse rotation does not affect each other.
The top end of the tensioning plate 56 is connected with the left end of the cutting platform 71, and the bottom end is connected with one end of the non-closed chain 51; the top end of the chain connecting plate 57 is fixedly connected with the right end of the cutting platform 71, the bottom end is connected with one end of the non-closed chain 51, and the non-closed chain 51 is connected with the synchronous sprocket 54 and the driven sprocket 52. A screw thread adjusting rod is arranged at the fixed connection position between the top end of the tensioning plate 56 and the left end of the cutting platform 71; the screw adjusting rod is fixedly connected with the left end of the cutting platform 71 and is in screw connection with the top end of the tensioning plate 56, and the distance between the tensioning plate 56 and the cutting platform 71 can be adjusted by rotating the screw adjusting rod, so that the tightness of the non-closed chain 51 is adjusted.
The number of teeth of the driven sprocket 52 is completely consistent with that of the outer edge gear of the driving fifth wheel 33; when the cutting platform 71 reciprocates along the platform bracket 74 under the driving of the driving cylinder 61, the cutting platform 71 simultaneously drives the non-closed chain 51 to reciprocate, thereby driving the synchronizing sprocket 54 and the driven sprocket 52 to simultaneously rotate.
The working principle of the invention is as follows: as shown in fig. 1: when the plastic profile a is conveyed to the cutting platform by the combined action of the lower conveying crawler 31 and the upper conveying crawler to start cutting, the cylinder 61 is first driven to quickly retract the driving rod, so that the whole cutting platform 71 moves leftwards at a running speed greater than that of the plastic profile a. And the cutting platform 71 is connected with the non-closed chain 51, and the non-closed chain 51 is connected with the synchronous sprocket 54 and the driven sprocket 52, so that the synchronous sprocket 54 and the driven sprocket 52 are driven to rotate synchronously. Since the driven sprocket 52 is engaged with each other when the rotational speed of the driven sprocket 52 is greater than the rotational speed of the pawl 53, the pawl 53 gives the driven sprocket 52 a resistance, and the rotating driven sprocket 52 is instantaneously decelerated and coincides with the rotational speed of the pawl 53. So that the speed of the retracting driving rod of the driving cylinder 61 is instantaneously reduced and kept consistent with the running speed of the lower conveyor track 31, i.e. the running speed of the cutting table 71 is consistent with the running speed of the plastic profile a.
Simultaneously, the first compression cylinder 81 and the second compression cylinder 84 respectively push the respective compression rubber blocks to downwards run to compress the plastic profile A, and the profile cutter 92 downwards runs to complete the action of the plastic profile A. Subsequently, the first pressing cylinder 81 and the second pressing cylinder 84 are both lifted up instantaneously and separated from the plastic profile a. Meanwhile, the driving rod of the driving cylinder 61 drives the cutting platform 71 to move rightward rapidly, and the driven sprocket 52 is driven to rotate simultaneously under the action of the non-closed chain 51, but the driven sprocket 52 and the ratchet wheel 53 do not affect each other when rotating reversely, so that the cutting platform 71 is not limited to move rightward, and can return to the initial position (namely the illustrated position) rapidly, and the whole cutting synchronization action is completed.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
