Description

Technical Field

[0001] This utility model relates to the field of cable material packaging technology, and in particular to a polyethylene cable material packaging mechanism. Background Technology

[0002] Currently, in the production process of polyethylene cable materials, the final finished product needs to be packaged. The packaging process usually uses a vacuum packaging machine, which can reliably vacuum seal the material, resulting in a small volume and stable quality of the packaged material.

[0003] A search revealed that CN216102972U discloses a polyethylene cable material packaging device. This device continuously extracts air from the packaging bag through a vacuum tube and an air vent to achieve vacuuming. However, due to the lack of a restraint device for the polyethylene cable material package, the surface of the packaged material is uneven. When stacking and storing the packaged material, there may be insufficient contact and support between adjacent packages, which may increase the risk of the package slipping. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a polyethylene cable material packaging mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A polyethylene cable packing mechanism includes a frame, an air vent, and a vacuum tube. The air vent is fixedly connected to the bottom end of the vacuum tube. A U-shaped frame is fixedly connected to the top center of the frame. Two baffles are fixedly connected to the top of the frame. A bidirectional lead screw is rotatably connected between the two baffles via bearings. A rotating motor is fixedly connected to one side of one of the baffles, and the output shaft of the rotating motor passes through the baffle and is fixed to the bidirectional lead screw via a coupling. Two square frames are threaded to the outer side of the bidirectional lead screw. Two round rods are fixedly connected to one side of each of the two square frames. One end of the two round rods on the same side passes through the U-shaped frame and is fixedly connected to a clamp. A clamping mechanism is provided between the two clamps to tightly fit the bag opening with the air vent. A sealing mechanism is provided between the two clamps below the clamping mechanism to seal the bag opening. The air vent is located above the clamps.

[0007] As a further embodiment of this utility model, the top of the frame is fixedly connected to two symmetrically distributed guide rails, and the guide rails are slidably connected to the frame.

[0008] As a further embodiment of this utility model, the clamping mechanism includes two clamping rods, which are disposed between two clamping frames. Two first guide rods are fixedly connected to one side of each clamping rod in opposite directions, and the first guide rods pass through the clamping frames. A blocking ring is fixedly connected to the outer side of each of the first guide rods. A spring is sleeved on the outer side of each of the first guide rods, and the two ends of the spring are fixed to the clamping frame and the blocking ring, respectively. A baffle is fixedly connected to one end of each of the first guide rods. A limiting groove is formed on one side of the two clamping rods facing each other, and the curvature of the limiting groove is adapted to the venting nozzle.

[0009] As a further embodiment of this utility model, the sealing mechanism includes two heat-conducting rods, both of which are disposed between clamps. A synchronous cylinder is fixedly connected to one side of each clamp in opposite directions, and the telescopic part of the synchronous cylinder passes through the clamp and is fixed to the heat-conducting rod.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By using clamps and U-shaped frames in combination, the two sides of the material bag are shaped, increasing the contact surface of the material bag when placed, effectively preventing the material bag from slipping due to insufficient contact surface, and ensuring the stability and safety of the material bag during storage and transportation.

[0015] 2. By setting up a clamping mechanism, the mechanism can quickly remove the air inside the material bag when vacuuming the bag and effectively prevent the infiltration of outside air, thereby achieving the set vacuum level in a short time and significantly improving the efficiency of vacuuming.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0023] Reference Figures 1-4A polyethylene cable packing mechanism includes a frame 1, an vent 6, and a vacuum tube 7. The vent 6 is bolted to the bottom end of the vacuum tube 7. A U-shaped frame 5 is bolted to the center of the top of the frame 1. Two stop bars 8 are bolted to the top of the frame 1. A bidirectional screw 9 is rotatably connected between the two stop bars 8 via a bearing. A rotating motor is bolted to one side of one of the stop bars 8, and the output shaft of the rotating motor passes through the stop bar 8 and is fixed to the bidirectional screw 9 via a coupling. Two square frames 2 are threaded to the outer side of the bidirectional screw 9. One side of each adjacent square frame 2 is bolted to the other side. Two round rods 3 are fixed on the same side. One end of the two round rods 3 passes through the U-shaped frame 5 and is fixed to the clamp 4 by bolts. The clamp 4 can contact the U-shaped frame 5. First, the material bag is placed on the U-shaped frame 5. Then, the rotating motor drives the bidirectional lead screw 9 to rotate, causing the two square frames 2 to move synchronously in opposite directions along the guide rail 10 with the round rods 3. This achieves the compression of both sides of the material bag, thereby achieving the shaping of both sides of the material bag. This increases the contact surface of the material bag when it is placed, effectively preventing the material bag from slipping due to insufficient contact surface, and ensuring the stability and safety of the material bag during storage and transportation.

[0024] In this invention, a clamping mechanism is provided between the two clamping frames 4 to tightly fit the bag opening and the venting nozzle 6. The clamping mechanism includes two clamping rods 12, which are positioned between the two clamping frames 4. Two first guide rods 14 are bolted to opposite sides of each clamping rod 12, and the first guide rods 14 pass through the clamping frames 4. A blocking ring is welded to the outer side of each of the first guide rods 14, and a spring 11 is sleeved on the outer side of each of the first guide rods 14. The two ends of the spring 11 are fixed to the clamping frame 4 and the blocking ring, respectively. A baffle is welded to one end of each of the first guide rods 14. A limiting groove 13 is provided on the facing side of each of the two clamping rods 12, and the curvature of the limiting groove 13 is adapted to the venting nozzle 6. At the same time, the venting nozzle 6 needs to be manually placed into the bag, and the height of the venting nozzle 6 is level with the height of the limiting groove 13. The relative movement of the clamping frames 4 causes the two clamping rods 12 to be pressed towards the center along the axial direction of the first guide rods 14, while the limiting groove 13... The card is located inside the bag's vent 6. Vacuuming is performed on the material bag using the vacuum tube 7. The two clamping rods 12 are tightly fitted by the squeezing force of the spring 11, which ensures that the air inside the material bag can be quickly removed when vacuuming, thus significantly improving the efficiency of vacuuming.

[0025] Specifically, a sealing mechanism for sealing the bag opening is provided between the two clamps 4, below the clamping mechanism. An venting nozzle 6 is located above the clamps 4. The sealing mechanism includes two heat-conducting rods 16, both positioned between the clamps 4. A synchronous cylinder is bolted to one side of each clamp 4, and the telescopic portion of the synchronous cylinder passes through the clamp 4 and is fixed to the heat-conducting rod 16. One heat-conducting rod 16 has a groove containing a heating wire. A silicone pad 17 is adhered to one side of the other heat-conducting rod 16. Two second guide rods 15 are bolted to the opposite sides of each heat-conducting rod 16. Passing through the clamp 4, the silicone pad 17 has evenly arranged protrusions on its surface, which can increase the contact area and friction with the sealing material during the heat sealing process, thereby effectively improving the sealing effect after heat sealing. After vacuuming, the heat-conducting rod 16 is preheated by a heating wire. When the synchronous cylinder is started, the telescopic part pushes the two heat-conducting rods 16 to move towards the center along the axis of the second guide rod 15. At this time, the heated heat-conducting rods 16 and the heat-conducting rods 16 with silicone pads 17 will clamp the bag and complete the heat sealing. After vacuuming, the package is heat-sealed, which effectively improves the sealing performance, prevents the entry of external air and moisture, and achieves the effect of long-term preservation of the package.

[0026] In particular, a multi-stage electric push rod 19 is fixed inside the frame 1 by bolts. The telescopic part of the multi-stage electric push rod 19 is fixed with a U-shaped baffle 18 by bolts, and the U-shaped baffle 18 can contact the clamp 4. While the square frame 2 moves, the multi-stage electric push rod 19 inside the frame 1 causes the U-shaped baffle 18 to rise and restrict the other two sides of the material bag, thereby realizing the straightening treatment of the other two sides of the material bag. The top of the frame 1 is fixed with two symmetrically distributed guide rails 10 by bolts, and the guide rails 10 are slidably connected to the square frame 2 to ensure the stability of the clamp 4 when it moves, so that the square frame 2 moves along the direction of the guide rails 10, making its movement more stable.

[0027] Working principle: First, place the bag on the U-shaped frame 5. Then, start the rotating motor to drive the bidirectional lead screw 9 to rotate, causing the two square frames 2, along with the round rods 3, to move synchronously in opposite directions along the guide rail 10. This achieves compression of both sides of the bag, thus straightening both sides of the bag and increasing the contact surface when the bag is placed. This effectively prevents the bag from slipping due to insufficient contact surface, ensuring the stability and safety of the bag during storage and transportation. While the square frames 2 move, the multi-stage electric push rods 19 inside the frame 1 raise the U-shaped baffle 18 and restrict the other two sides of the bag, thus straightening the other two sides of the bag. At the same time, the vent 6 needs to be manually placed into the bag, with the height of the vent 6 level with the height of the limiting groove 13. The relative movement of the clamps 4 causes the two clamping rods 12 to be squeezed towards the center along the axial direction of the first guide rod 14, while simultaneously passing through the limiting groove 13. The card is located inside the bag's vent 6. Vacuuming is performed using the vacuum tube 7 to align the bag and apply vacuum. The compression force of the spring 11 causes the two clamping rods 12 to fit tightly together, ensuring that air can be quickly removed from the bag during vacuuming, thus significantly improving vacuuming efficiency. After vacuuming, the heating rods 16 are preheated by the heating wire. Then, the synchronous cylinder is activated, and the telescopic part pushes the two heating rods 16 to move towards the center along the axis of the second guide rod 15. At this time, the heated heating rods 16 and the heating rod with silicone pad 17 clamp the bag to complete the heat sealing. The heat sealing of the bag after vacuuming effectively improves the airtightness, preventing the entry of external air and moisture, and achieving the effect of long-term preservation of the bag. After completion, the reverse rotation of the rotating motor drives the clamp 4 to open, allowing the packaged bag to be unloaded.

[0028] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
