Description

Technical Field

[0001] This utility model relates to the field of waste material winding technology, specifically a winding mechanism for collecting edge-cut waste materials. Background Technology

[0002] Plastic packaging bags are made from plastic and are used to package various daily necessities. They are widely used in daily life and industrial production, but this convenience brings long-term harm. Most commonly used plastic packaging bags are made of polyethylene film, which is non-toxic and therefore suitable for food packaging.

[0003] During the production of plastic packaging bags, a relatively wide edge is left at the edge. When the plastic packaging bags need to be packaged, the excess edge needs to be cut off. The waste material from the cut edge needs to be collected to prevent it from affecting the equipment. However, the existing waste material winding mechanism only uses a winding roller to wrap the waste material, which makes the waste material wrapped on the winding roller very uneven.

[0004] Therefore, we propose a winding mechanism for collecting edge-cutting waste. Utility Model Content

[0005] The purpose of this invention is to provide a winding mechanism for collecting edge-cut waste, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a winding mechanism for collecting edge-cut waste, comprising a base plate, a movable groove fixedly installed on the top of the base plate, a drive motor fixedly installed on one side of the movable groove, a take-up roller rotatably connected to the top of the base plate on one side of the drive motor, a reciprocating screw rotatably connected inside the movable groove, the output end of the drive motor being drivenly connected to one end of the reciprocating screw, a movable block rotatably connected to the reciprocating screw through a threaded connection inside the movable groove, the movable block being slidably connected to the inside of the movable groove, a support rod rotatably connected to the top of the movable block near the take-up roller, a guide roller rotatably connected to the top of the support rod, an elastic bracket rotatably connected to the top of the movable block away from the take-up roller, the top of the elastic bracket being rotatably connected to the top of one side of the support rod, and the other end of the reciprocating screw being drivenly connected to one end of the take-up roller.

[0007] Optionally, a first synchronous pulley is fixedly installed at the output end of the drive motor, and a second synchronous pulley located outside the moving groove is fixedly installed at one end of the reciprocating screw. The first synchronous pulley is connected to the second synchronous pulley via a first synchronous belt.

[0008] Optionally, a third synchronous pulley located outside the moving groove is fixedly installed at the other end of the reciprocating screw, and a fourth synchronous pulley is fixedly installed at one end of the take-up roller. The third synchronous pulley is connected to the fourth synchronous pulley via a second synchronous belt.

[0009] Optionally, a guide slide rod located above the reciprocating screw is fixedly installed inside the moving groove, and the guide slide rod is slidably connected to the moving block through it.

[0010] Optionally, the elastic support includes a telescopic sleeve rotatably connected to the top of the movable block, a piston plate slidably connected inside the telescopic sleeve, a telescopic rod integrally connected to the top of the piston plate, the top of the telescopic rod rotatably connected to a support rod, and a contraction spring sleeved on the outside of the telescopic rod.

[0011] Optionally, the top of the contraction spring is in close contact with the top of the inside of the telescopic sleeve, the other end of the contraction spring is in close contact with the top of the piston plate, and the telescopic rod is slidably connected to the top of the telescopic sleeve.

[0012] Optionally, the bottom of the take-up roller is higher than the top of the moving trough, and the top of the take-up roller is lower than the bottom of the guide roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The winding mechanism for collecting edge-cut waste material is equipped with a reciprocating screw, which is driven by a motor to rotate. At the same time, the third synchronous wheel, the fourth synchronous wheel, and the second synchronous belt drive the take-up roller to rotate synchronously. When the edge waste material passes through the guide roller and wraps around the take-up roller, the moving block moves back and forth in the moving groove as the reciprocating screw rotates, so that the support rod drives the edge waste material to move back and forth, so that the wound edge waste material can be smoothly and tightly wrapped around the take-up roller.

[0015] 2. The winding mechanism for collecting edge-cut waste material has an elastic support. When the winding roller winds up the edge waste material, and the deflecting roller is pulled by the edge waste material, the telescopic rod in the elastic support extends outward, causing the piston plate to squeeze the compression spring. When the edge waste material stops pulling, the telescopic rod retracts into the telescopic sleeve under the action of the compression spring, thereby resetting the guide roller and preventing the edge waste material from breaking during winding.

A flexible bracket 9 is rotatably connected to the top of block 6 away from the take-up roller 4. The top of the flexible bracket 9 is rotatably connected to the top of one side of the support rod 7. The other end of the reciprocating screw 5 is connected to one end of the take-up roller 4. By setting the reciprocating screw 5, the drive motor 3 drives the reciprocating screw to rotate. At the same time, the take-up roller 4 is driven to rotate synchronously through the third synchronous wheel 13, the fourth synchronous wheel 15 and the second synchronous belt 14. When the edge waste passes through the guide roller 8 and wraps around the take-up roller 4, as the reciprocating screw 5 rotates, the moving block 6 moves back and forth in the moving groove 2, so that the support rod 7 drives the edge waste to move back and forth, so that the wound edge waste can be smoothly and tightly wrapped around the take-up roller 4.

[0023] A first synchronous pulley 10 is fixedly installed at the output end of the drive motor 3. A second synchronous pulley 12 located outside the moving groove 2 is fixedly installed at one end of the reciprocating screw 5. The first synchronous pulley 10 is connected to the second synchronous pulley 12 via a first synchronous belt 11. A third synchronous pulley 13 located outside the moving groove 2 is fixedly installed at the other end of the reciprocating screw 5. A fourth synchronous pulley 15 is fixedly installed at one end of the take-up roller 4. The third synchronous pulley 13 is connected to the fourth synchronous pulley 15 via a second synchronous belt 14. A guide slide rod 16 located above the reciprocating screw 5 is fixedly installed inside the moving groove 2. The guide slide rod 16 is slidably connected to the moving block 6. The elastic bracket 9 includes a telescopic sleeve 91 rotatably connected to the top of the moving block 6. A piston plate 92 is slidably connected inside the telescopic sleeve 91. A telescopic rod 93 is integrally connected to the top of the piston plate 92. The telescopic rod 93 is rotatably connected to the support rod 7. A contraction spring 94 is sleeved on the outside of the telescopic rod 93. The top of the contraction spring 94 is in close contact with the top of the inside of the telescopic sleeve 91, and the other end of the contraction spring 94 is in close contact with the top of the piston plate 92.

The bottom of the take-up roller 4 is higher than the top of the moving groove 2, and the top of the take-up roller 4 is lower than the bottom of the guide roller 8. By setting the elastic bracket 9, when the take-up roller 4 takes up the edge waste, when the deflecting roller is pulled by the edge waste, the telescopic rod 93 in the elastic bracket extends outward, so that the piston plate 92 squeezes the contraction spring 94. When the edge waste is no longer pulled, under the action of the contraction spring 94, the telescopic rod 93 retracts into the telescopic sleeve 91, thereby resetting the guide roller 8 and preventing the edge waste from breaking during the winding process.

[0024] Working principle:

[0025] The drive motor 3 drives the reciprocating screw to rotate, and simultaneously drives the take-up roller 4 to rotate synchronously through the third synchronous wheel 13, the fourth synchronous wheel 15 and the second synchronous belt 14. When the edge waste passes through the guide roller 8 and wraps around the take-up roller 4, as the reciprocating screw 5 rotates, the moving block 6 moves back and forth in the moving groove 2, so that the support rod 7 drives the edge waste to move back and forth, so that the wound edge waste can be smoothly and tightly wrapped around the take-up roller 4. When the take-up roller 4 winds up the edge waste, when the deflecting roller is pulled by the edge waste, the telescopic rod 93 in the spring wire bracket extends outward, so that the piston plate 92 squeezes the compression spring 94. When the edge waste is no longer pulled, under the action of the compression spring 94, the telescopic rod 93 retracts into the telescopic sleeve 91, thereby resetting the guide roller 8 and preventing the edge waste from breaking during the winding process.
