A fixed frame 7 is slidably connected to the inner side of the material receiving frame 5, and a sleeve frame 8 for putting on a bag is fixedly connected to the side wall of the fixed frame 7, and a clamping mechanism for clamping the sleeved bag is provided on the fixed frame 7; A driving groove 9 is provided at the top of the unloading platform 3 and below the material receiving frame 5, a driving mechanism for driving the fixed frame 7 to move is provided inside the driving groove 9, sliding grooves 10 are provided on both sides of the outer wall of the material receiving frame 5, sliding blocks 11 are slidably connected inside the sliding grooves 10, upper rectangular grooves 12 are provided at both ends of the inner side of the material receiving frame 5, a lower rectangular groove 13 is provided at the top of the unloading platform 3 and between the upper rectangular groove 12 and the fixed frame 7, and the upper rectangular groove 12 and the lower rectangular groove 13 are both inclined away from the fixed frame 7. An upper rectangular plate 14 is provided on the side close to the sliding block 11 and located in the upper rectangular groove 12, and a sliding rod 15 is fixedly connected to the side away from the upper rectangular plate 14 and penetrates the inner wall of the sliding block 11, an upper spring 16 is fixedly connected between the outer wall of the sliding rod 15 and the side wall of the sliding block 11, a lower rectangular plate 17 is provided on the inner side of the lower rectangular groove 13, a lower plate 18 is provided below the lower rectangular plate 17, a pair of bottom rods 19 are fixedly connected to the bottom of the lower rectangular plate 17, and lower springs 20 are fixedly connected between the outer walls of the bottom rods 19 and the bottom of the lower plate 18, the lower plate 18 is fixedly connected to the side wall of the fixed frame 7, a connecting plate 21 is fixedly connected between the side wall of the sliding block 11 and the side wall of the fixed frame 7, the side walls of the upper rectangular plate 14 and the lower rectangular plate 17 are inclined, and a sliding frame 22 is fixedly connected to the side wall of the receiving frame 5 and the position corresponding to the slide groove 10; The driving mechanism includes a driving motor 39, a threaded rod 40 is rotatably connected to the inner side of the driving groove 9, a driving block 41 is threadedly connected to the outer wall of the threaded rod 40, the driving motor 39 is fixedly connected to the side wall of the unloading platform 3, the output end of the driving motor 39 passes through the inner side of the slide groove 10 and is fixedly connected to the side wall of the threaded rod 40, and the top of the driving block 41 is fixedly connected to the bottom of the fixed frame 7; During the process of producing PPR pipes by the extrusion component 1, the cooling and molding component 2 and the unloading mechanism 4, the produced and molded PPR pipes are unloaded into the receiving frame 5 through the unloading mechanism 4. During this process, the empty bag can be put on the sleeve frame 8, and the bag can be clamped on the sleeve frame 8 through the clamping mechanism. Then, when a certain number of PPR pipes are collected inside the receiving frame 5, the baffle 43 can be inserted into the slot, and then the driving motor 39 of the driving mechanism is controlled to start and drive the threaded rod 40 to rotate, thereby driving the threaded driving block 41 to move, and then driving the fixed frame 7 and the sleeve frame 8 to move, thereby driving the bag to move to one side of the PPR pipe. During this process, the sliding of the fixed frame 7 will drive the lower plate 18 to move, and the connecting plate 21 will push the sliding block 11 to slide on the inner side of the slide groove 10, thereby pushing the upper rectangular plate 14 and the lower rectangular plate 17 to move; At this time, the upper rectangular plate 14 and the lower rectangular plate 17 are located in the upper rectangular groove 12 and the lower rectangular groove 13, and the side walls of the upper rectangular groove 12 and the lower rectangular groove 13 are inclined surfaces. Therefore, when the upper rectangular plate 14 and the lower rectangular plate 17 move, they will be squeezed by the inclined surfaces of the upper rectangular groove 12 and the lower rectangular groove 13, and the upper rectangular plate 14 and the lower rectangular plate 17 will be pushed out of the upper rectangular groove 12 and the lower rectangular groove 13, and the sliding rod 15 and the bottom rod 19 will slide, and the upper spring 16 and the lower spring 20 will be compressed. In this process, the upper rectangular plate 14 will push the PPR tube in the receiving frame 5 to the middle, and at the same time, the PPPR tube will be pushed into the receiving frame 5 through the lower rectangular plate 17. The R tube is pushed upward to squeeze the PPR tube together, which is convenient for subsequent insertion into the fixed frame 7 and then inserted into the bag. Then, under the continued drive of the driving mechanism, the fixed frame 7 is passed through the squeezed PPR tube, so that the bag is put on the PPR tube. Then, the upper rectangular plate 14 and the lower rectangular plate 17 will first slide out of the outside of the PPR tube, and then the fixed frame 7 will slide out of the PPR tube. At this time, the sliding block 11 and the lower plate 18 will slide out of the slide groove 10 of the receiving frame 5, and the sliding block 11 will slide into the sliding frame 22. At this time, the bag has been completely put on the PPR tube, and then the lifting mechanism is controlled to operate to release the clamping of the bag and eject the PPR tube.

[0023] In order to firmly clamp the bag, the clamping mechanism includes a clamping plate 23, a T-shaped frame 24 is fixedly connected to the side wall of the fixed frame 7 and located on both sides of the sleeve frame 8, a pair of clamping plates 23 are provided, and the clamping plates 23 are slidably connected to the side wall of the fixed frame 7, and the side away from the clamping plate 23 is fixedly connected to an upper right-angle block 44 with an inclined surface, and the inner side of the T-shaped frame 24 is slidably connected to a clamping frame 25, and the side of the clamping frame 25 is fixedly connected to an extrusion rod 26 for extruding the inclined surface of the upper right-angle block 44, and the side wall of the clamping frame 25 is slidably connected to a locking block 27, and the top of the side wall of the locking block 27 is inclined; Several lower right-angle blocks 28 with inclined surfaces are fixedly connected to the inner side of the T-frame 24 and at the positions corresponding to the locking blocks 27. A locking spring 29 is fixedly connected between the side wall of the locking block 27 and the inner side of the clamping frame 25. A loading cavity 30 is provided inside the unloading platform 3 and on both sides of the driving groove 9. A lifting mechanism for unlocking the bag clamping and ejecting the bag pipe is provided in the loading cavity 30. Three reset springs 31 are fixedly connected between the side walls of the clamping plate 23 and the side walls of the T-frame 24. Through the setting of the reset springs 31, the clamping plate 23 can be quickly pulled to reset and the clamping and fixing of the bag can be released. The ends of the extrusion rods 26 are all set to smooth arc surfaces, which are convenient for better extrusion of the upper right-angle blocks 44. The side walls of the clamping frame 25 are fixedly connected with a pushing block 32. Through the setting of the pushing block 32, it is convenient for workers to push the clamping frame 25 to slide upward, drive the clamping plate 23 to quickly clamp the bag on the fixed frame 7, and greatly improve the convenience performance during the operation of the device. Before bagging the PPR pipe, put the end of the empty bag on the sleeve frame 8, then push the pushing blocks 32 on both sides upward to drive the clamping frame 25 to slide upward, and then drive the extrusion rod 26 to slide upward to squeeze the inclined surface of the upper right-angle block 44, thereby pushing the upper right-angle block 44 to move, clamping the bag between the clamping plate 23 and the side wall of the sleeve frame 8, and gradually stretching the reset spring 31 outward, and gradually compressing the unlocking spring 36 when the clamping frame 25 slides upward. In this process, the upward sliding of the clamping frame 25 will drive the locking spring 36 to slide upward. The block 27 slides upward, at which time the inclined surface of the lower right-angle block 28 will squeeze the inclined surface on the locking block 27, thereby squeezing the locking block 27 into the clamping frame 25 and gradually compressing the locking spring 29. Subsequently, when the locking block 27 slides out of the extrusion surface of the lower right-angle block 28, the locking block 27 will be pushed into the inclined surface of the lower right-angle block 28 under the elastic force of the locking spring 29. This process is repeated to push the clamping frame 25 to a position where the bag can be clamped, and at this time the locking block 27 is stuck on the inclined surface of the lower right-angle block 28, thereby fixing the position of the clamping frame 25.

[0024] In order to automatically release the clamping of the bag and push the PPR pipe with the belt out of the receiving frame 5, the lifting mechanism includes an electric telescopic cylinder 33, and the electric telescopic cylinder 33 is provided with two pairs, and each pair of electric telescopic cylinders 33 is fixedly connected to the bottom end of the feeding chamber 30, and a top plate 34 is fixedly connected between the output ends of each pair of electric telescopic cylinders 33, and a lifting block 35 is fixedly connected to the top of the top plate 34, and a top groove is provided at the top of the unloading platform 3 and at a position corresponding to the lifting block 35, an unlocking spring 36 is fixedly connected between the top of the clamping frame 25 and the inner side of the T-frame 24, and the side walls of the locking block 27 are fixedly connected with round rods 37, and the side ends of the top plate 34 are fixedly connected with positioning rods 38 and are arranged to penetrate the outer wall of the unloading platform 3, and the top end of the positioning rod 38 is inclined; After the driving mechanism puts the bag on the PPR pipe, the round rod 37 moves to the top of the positioning rod 38, and then the electric telescopic cylinder 33 of the jacking mechanism can be controlled to start pushing the top plate 34 to slide upward, which will first drive the positioning rod 38 at the side end to move upward, thereby squeezing the round rod 37 through the inclined surface above the positioning rod 38 to move, thereby driving the locking block 27 to slide out from the lower right-angle block 28, and gradually compressing the locking spring 29, and then the round rod 37 moves to the side of the positioning rod 38, thereby releasing the sliding restriction on the clamping frame 25, and then pushing the clamping frame 25 to slide downward under the elastic force of the unlocking spring 36, while driving the squeezing rod 2 6 slides downward, thereby releasing the squeezing of the upper right-angle block 44, and then pulls the clamping plate 23 to slide and reset under the elastic force of the reset spring 31, thereby releasing the clamping of both sides of the bag, and then under the continued driving of the electric telescopic cylinder 33, the lifting block 35 is driven to slide out of the top groove, and then the PPR tube that has just been bagged is pushed out of the receiving frame 5, and the end of the bag is pulled out of the fixed frame 7 under the pulling force of the lifting, so that the worker does not need to lift the PPR tube out, further improving the convenience of the device. Finally, the worker wraps the end of the bag with tape to seal it, and then takes away the packaged PPR tube, and then controls the electric telescopic cylinder 33 to move in the opposite direction and reset.

[0025] In order to limit the PPR pipe being unloaded, limiting plates 42 are fixedly connected to both sides of the top of the guide platform 6, and the two ends of one of the limiting plates 42 extend to the side of the unloading mechanism 4 and above the receiving frame 5 respectively. Through the setting of the limiting plate 42, a guiding effect can be played on the PPR pipe flipped out by the unloading mechanism 4, thereby preventing the PPR pipe from rolling down at will and affecting the normal operation of subsequent packaging work.

[0026] In order not to affect the normal operation of the unloading mechanism 4, a slot is opened on the top of the limit plate 42, and a baffle 43 is inserted in the slot. Through the arrangement of the slot and the baffle 43, the material guide table 6 and the material receiving frame 5 can be separated during the packaging of the PPR pipe, thereby preventing the PPR pipe unloaded by the unloading mechanism 4 from falling into the normally packaged material receiving frame 5, thereby not affecting the normal operation of the device, and the baffle 43 can be taken out after the packaging is completed, and the PPR pipe on the material guide table 6 will fall into the material receiving frame 5 under its own gravity.

[0029] Those skilled in the art should understand that the present invention is not limited to the above-mentioned embodiments. The above-mentioned embodiments and the specification only describe the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. These changes and improvements all fall within the scope of the present invention to be protected.
