[0002] When the palletizer is packaging on the production line, the pipes next to the PVC packaging machine are prone to dust accumulation due to the operating environment. PVC granules may also accumulate in the feeding pipes, causing blockages and affecting normal feeding operations, thus reducing feeding efficiency. Utility Model Content

[0003] In order to promptly remove PVC powder adhering to the pipe walls, improve the smoothness of powder discharge, and increase powder discharge efficiency, this application provides a pipe vibration system for PVC packaging machines.

[0004] The technical solution provided in this application for a pipeline vibration system applied to a PVC packaging machine is as follows:

[0005] A pipeline vibration system for a PVC packaging machine includes a support frame placed on the ground, a storage bin installed on the side of the support frame away from the ground, a receiving device installed on the ground, a discharge pipeline installed between the storage bin and the receiving device, and a vibration device mounted on the support frame for vibrating the discharge pipeline. The vibration device includes a first vibration component and a second vibration component mounted on the support frame. The first vibration component includes a first push cylinder. When the piston rod of the first push cylinder extends, the end of the piston rod abuts against the discharge pipeline.

[0006] By adopting the above technical solution, when in use, the operator operates the first vibration component and the second vibration component, causing the piston rod of the first push cylinder to extend and vibrate the feeding pipe, so that the powder hanging on the wall of the pipe is removed in time through vibration, making the powder feeding smoother and thus improving the powder feeding efficiency.

[0007] Optionally, the support frame includes a support leg, a placement platform fixedly connected to the side of the support leg away from the ground, and a reinforcing plate fixedly connected between the support leg and the placement platform.

[0008] Optionally, the first vibration assembly further includes a first mounting plate fixedly connected to the side wall of the support leg and a first vibration plate disposed at one end of the piston rod of the first push cylinder.

[0009] By adopting the above technical solution, when in use, the operator operates the piston rod of the first push cylinder to extend, and the first vibrating plate abuts against the feeding pipe, thereby vibrating the feeding pipe. The setting of the first vibrating plate increases the vibration efficiency of the piston rod of the first push cylinder on the feeding pipe.

[0010] Optionally, the second vibration assembly includes a second push cylinder mounted on the side of the placement platform away from the ground and a second vibration plate fixedly connected to the piston rod of the second push cylinder, wherein the length direction of the second push cylinder is perpendicular to the length direction of the first push cylinder.

[0011] By adopting the above technical solution, when in use, the operator operates the piston rod of the second push cylinder to extend, and the piston rod of the second push cylinder vibrates the feeding pipe. By vibrating the feeding pipe at different angles and positions, the powder hanging on the wall is removed more thoroughly and quickly, resulting in higher efficiency.

[0012] Optionally, a lifting device for driving the first vibration component to rise and fall is installed on one side of the support frame.

[0013] By adopting the above technical solution, when in use, the staff operates the lifting device to move the first vibration component in the vertical direction, accurately striking the parts of the feeding pipe where powder is stuck on the wall, thus making the removal efficiency of the stuck powder higher and improving the powder feeding efficiency.

[0014] Optionally, the lifting device includes a mounting box mounted on the support frame, a lifting platform for mounting the first vibration component, a mounting frame disposed on the side of the lifting platform near the mounting box, and a sprocket and chain assembly for driving the lifting platform to rise and fall. The mounting frame is used to mount the sprocket and chain assembly, and a groove is provided on one side of the mounting box for moving the piston rod of the first push cylinder.

[0015] By adopting the above technical solution, when in use, the operator operates the sprocket and chain assembly to drive the lifting platform to move vertically, thereby driving the first push cylinder to move vertically.

[0016] Optionally, the sprocket and chain assembly includes a drive shaft rotatably connected in the mounting box, a driven shaft rotatably connected in the mounting box, a drive motor fixedly connected to the mounting frame, a drive sprocket fixedly connected to the drive shaft, a driven sprocket fixedly connected to the driven shaft, a movable sprocket assembly disposed between the drive sprocket and the driven sprocket, and a transmission chain, wherein the movable sprocket assembly is connected to the lifting platform.

[0017] By adopting the above technical solution, when in use, the staff starts the drive motor, which drives the drive shaft to rotate, and the drive sprocket rotates accordingly. The drive sprocket and the movable sprocket group are moved through the transmission chain.

[0018] Optionally, the movable sprocket assembly includes two movable plates fixedly connected to the side of the lifting platform away from the slide groove, an active movable shaft rotatably connected between the two movable plates, a driven movable shaft rotatably connected between the two movable plates, an upper movable sprocket fixedly connected to the active movable shaft, and a lower movable sprocket fixedly connected to the driven movable shaft. Both the upper movable sprocket and the lower movable sprocket mesh with the transmission chain.

[0019] Optionally, the receiving device includes a bracket placed on the ground, a receiving hopper mounted on the bracket, a valve disposed on the receiving hopper, and a fastening assembly disposed on the side of the receiving hopper near the ground for securing the packaging bag.

[0020] By adopting the above technical solution, when in use, the staff fixes the packaging bag to the end of the receiving hopper near the ground using the fastening components, opens the valve, and allows the powder to directly enter the packaging bag, reducing the possibility of powder escaping during the receiving process at the bag opening, reducing environmental pollution, and improving powder recycling efficiency.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. This application uses a vibration device, including a first vibration component and a second vibration component, to vibrate different positions and angles of the feeding pipe, so that the powder stuck in the feeding pipe is removed from the stuck point in time, making the feeding smoother and thus improving the powder feeding efficiency.

[0023] 2. This application sets up a lifting device so that the first vibration component can move in the vertical direction. When the staff observes that powder is stuck on the wall in the feeding pipe, the staff starts the drive motor so that the first vibration component moves to the powder stuck place and vibrates the feeding pipe, thereby improving the vibration efficiency and further improving the powder feeding efficiency.

[0024] 3. This application reduces the gap between the packaging bag opening and the discharge pipe by setting up a receiving device and fastening components on the discharge pipe of the receiving hopper, thereby reducing the possibility of powder moving out when receiving material from the packaging bag opening, reducing pollution to the surrounding environment, and improving the powder collection rate.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses a pipeline vibration system for use in PVC packaging machines.

[0032] Example 1

[0033] Reference Figure 1 A pipe vibration system for a PVC packaging machine includes a support frame 1 placed on the ground, a storage bin 2 installed on the side of the support frame 1 away from the ground, a receiving device 3 installed on the ground, a discharge pipe 4 installed between the storage bin 2 and the receiving device 3, and a vibration device 5 installed on the support frame 1 for vibrating the discharge pipe 4. The support frame 1 includes a support leg 11, a placement platform 12 fixedly connected to the side of the support leg 11 away from the ground, and a reinforcing plate 13 fixedly connected between the support leg 11 and the placement platform 12.

[0034] The vibrating device 5 includes a first vibration component 51 mounted on the support frame 1. The first vibration component 51 includes a first mounting plate 511 fixedly connected to the side wall of the support leg 11 and a first push cylinder 512 fixedly connected to the side of the first mounting plate 511 away from the support leg 11. When the piston rod of the first push cylinder 512 extends, the end of the piston rod of the first push cylinder 512 abuts against the side wall of the feed pipe 4.

[0035] In use, the operator operates the first push cylinder 512, causing the piston rod of the first push cylinder 512 to extend and retract. When the end of the piston rod of the first push cylinder 512 abuts against the side wall of the feeding pipe 4, the thrust of the piston rod of the first push cylinder 512 causes the feeding pipe 4 to start oscillating from a static state, thereby removing the powder stuck in the feeding pipe 4 from the stuck point, making the powder in the feeding pipe 4 fall more smoothly and improving the feeding rate.

[0036] Reference Figure 1 To vibrate the feeding pipe 4 at different angles, thereby providing a more comprehensive thrust and further improving feeding efficiency, the vibrating device 5 also includes a second vibration assembly 52 mounted on the support frame 1. The second vibration assembly 52 includes a second push cylinder 521 mounted on the side of the placement platform 12 away from the ground. The piston rod of the second push cylinder 521 moves in a direction perpendicular to the piston rod of the first push cylinder 512. After extending a certain distance, the end of the piston rod of the second push cylinder 521 abuts against the feeding pipe 4.

[0037] During use, the operator operates the first push cylinder 512 and the second push cylinder 521, causing the piston rods of the first push cylinder 512 and the second push cylinder 521 to extend and vibrate at different positions of the feeding pipe 4, so that the powder in the feeding pipe 4 falls more smoothly and the feeding rate is increased.

[0038] Since the feeding pipe 4 is a free pipe, it may move during the vibration process. In order to increase the probability that the piston rod end of the first pushing cylinder 512 and the piston rod end of the second pushing cylinder 521 will contact the feeding pipe 4 when they extend, the piston rod end of the first pushing cylinder 512 is fixedly connected to the first vibrating plate 513, and the piston rod end of the second pushing cylinder 521 is fixedly connected to the second vibrating plate 522.

[0039] In use, when the piston rod of the first push cylinder 512 extends, the first vibrating plate 513 abuts against the feeding pipe 4, and when the piston rod of the second push cylinder 521 extends, the second vibrating plate 522 abuts against the feeding pipe 4, thus vibrating the feeding pipe 4.

[0040] Reference Figure 1 and Figure 2Because the feeding pipe 4 is relatively long, when the piston rod of the first push cylinder 512 extends to vibrate the feeding pipe 4, the feeding pipe 4 may move significantly in the air. When the feeding pipe 4 swings, the vibrating device 5 cannot vibrate the feeding pipe 4, which reduces the working efficiency of the vibrating device 5.

[0041] To reduce the swaying amplitude of the feeding pipe 4, multiple retractable components 14 are spaced apart on the support frame 1. Each retractable component 14 includes a connecting rod 141 fixedly connected to the support leg 11 and a rubber ring 142 fixedly connected to the end of the connecting rod 141 away from the support leg 11. The diameter of the rubber ring 142 is larger than the diameter of the feeding pipe 4, and the rubber ring 142 is elastic. In use, the retractable components 14 limit the swaying amplitude of the feeding pipe 4, improving the efficiency of the vibrating device 5 in vibrating the feeding pipe 4.

[0042] Reference Figure 2 The receiving device 3 includes a support 31 placed on the ground, a receiving hopper 32 installed on the support 31, and a valve (not shown in the figure) installed on the receiving hopper 32. The receiving hopper 32 is funnel-shaped, and a discharge pipe 33 is provided on the side of the receiving hopper 32 near the ground. When the valve is closed, the discharge pipe 33 of the receiving hopper 32 is closed.

[0043] When in use, the staff places the packaging bag under the discharge pipe 33 of the receiving hopper 32, opens the valve, and allows the powder in the receiving hopper 32 and the powder sliding from the discharge pipe 4 to fall into the packaging bag, thus completing the packaging and collection of the powder.

[0044] To facilitate the securing of the packaging bags placed at the discharge pipe 33 of the receiving hopper 32 and reduce the possibility of powder leaking out of the packaging bag opening, the receiving device 3 also includes a fastening component 34 for securing the packaging bags. The fastening component 34 includes a clamp 341 set on the discharge pipe 33 and a screw 342 for fixing the clamp 341. In use, the operator screws the screw 342 to open the clamp 341, then puts the packaging bag opening on the discharge pipe 33, and then screws the screw 342 in to close the clamp 341, thereby sealing the gap between the packaging bag opening and the discharge pipe 33 and reducing the possibility of powder leakage.

[0045] To protect the storage bin 2 installed on the side of the placement platform 12 away from the ground, a protective railing is provided on the side of the placement platform 12 away from the ground to protect the storage bin 2.

[0046] The implementation principle of Example 1 is as follows: When in use, the staff places the packaging bag into the discharge pipe 33 of the receiving hopper 32, opens the valve, and then operates the first push cylinder 512 and the second push cylinder 521 to move and vibrate the discharge pipe 4, so that the powder stuck in the discharge pipe 4 is removed from the stuck part, thereby increasing the discharge rate.

[0047] Example 2

[0048] Refer to Figure 3 and Figure 4 The difference between this embodiment and embodiment 1 is that this embodiment is provided with a lifting device 6 for driving the first vibration component 51 to move in the vertical direction.

[0049] Reference Figure 4 The lifting device 6 includes a mounting box 61 mounted on the support frame 1, a lifting platform 62 for mounting the first vibration component 51, a mounting frame 63 set on the inner wall of the mounting box 61, and a sprocket and chain assembly 64 for driving the lifting platform 62 to lift. The mounting box 61 has a groove 65 on the side near the discharge pipe 4 for moving the piston rod of the first push cylinder 512.

[0050] The sprocket and chain assembly 64 includes a drive shaft 641 rotatably connected to the mounting frame 63, a driven shaft 642 rotatably connected to the mounting frame 63, a drive motor 643 fixedly connected to the mounting frame 63 for driving the drive shaft 641 to rotate, a drive sprocket 644 fixedly connected to the drive shaft 641, a driven sprocket 645 fixedly connected to the driven shaft 642, a movable sprocket group 646 disposed between the drive sprocket 644 and the driven sprocket 645, and a transmission chain 647. The movable sprocket group 646 is connected to the lifting platform 62. There are two drive sprockets 644 and two driven sprockets 645. One drive sprocket 644 and one driven sprocket 645 form the first group, and the other drive sprocket 644 and the driven sprocket 645 form the second group. The drive sprockets 644 and the driven sprockets 645 in the same group are located on the same plane, and there are two transmission sprockets disposed opposite each other.

[0051] Reference Figure 4The movable sprocket assembly 646 includes two movable plates 6461 fixedly connected to the side of the lifting platform 62 away from the slide 65, an active movable shaft 6462 rotatably connected between the two movable plates 6461, a driven movable shaft 6463 rotatably connected between the two movable plates 6461, an upper movable sprocket 6464 fixedly connected to the active movable shaft 6462, and a lower movable sprocket 6465 fixedly connected to the driven movable shaft 6463. There are two upper movable sprockets 6464 and two lower movable sprockets 6465, and both upper movable sprockets 6464 and two lower movable sprockets 6465 are engaged with the drive chain 647. One upper movable sprocket 6464 and one lower movable sprocket 6465 constitute the third group, and the other upper movable sprocket 6464 and lower movable sprocket 6465 constitute the fourth group. The upper movable sprockets 6464 and lower movable sprockets 6465 in the same group are located on the same plane. The driving sprocket 644 and driven sprocket 645 of the first group and the upper movable sprockets 6464 and lower movable sprockets 6465 of the third group are located on the same plane. The driving sprocket 644 and driven sprocket 645 of the second group and the upper movable sprockets 6464 and lower movable sprockets 6465 of the fourth group are located on the same plane.

[0052] The mounting frame 63 is fixedly connected to an upper fixed seat 648 and a lower fixed seat 649 on the side away from the slide 65. The upper fixed seat 648 is located between the driving sprocket 644 and the upper movable sprocket 6464, and the lower fixed seat 649 is located between the driven sprocket 645 and the lower movable sprocket 6465. One end of the transmission chain 647 is fixedly connected to the upper fixed seat 648 and passes through the upper movable sprocket 6464, the driving sprocket 644, the driven sprocket 645 and the lower movable sprocket 6465 in sequence. The other end of the transmission chain 647 is fixedly connected to the lower fixed seat 649.

[0053] When in use, the operator starts the drive motor 643. The output shaft of the drive motor 643 rotates, thereby driving the drive shaft 641 to rotate. The drive sprocket 644 rotates accordingly, thereby driving the lifting platform 62 to move vertically. The first push cylinder 512 moves vertically, thereby vibrating different positions of the feeding pipe 4. This allows the vibrating device 5 to accurately vibrate the parts of the feeding pipe 4 where powder jamming occurs, improving the vibrating efficiency.

[0054] The implementation principle of Example 2 is as follows: When in use, the operator starts the drive motor 643. The output shaft of the drive motor 643 rotates, thereby driving the drive shaft 641 to rotate. The drive sprocket 644 rotates, and the transmission chain 647 moves, thereby driving the lifting platform 62 to move in the vertical direction. When the operator finds that there is a jam in the feeding pipe 4, the operator starts the drive motor 643, so that the lifting platform 62 moves to the position that needs to be vibrated. Then, the first push cylinder 512 is operated to vibrate the feeding pipe 4 at that position, thereby improving the vibration efficiency and further improving the feeding efficiency.

[0055] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
