Description

Technical Field

[0001] This utility model relates to the field of wire packaging technology, and in particular to a fully automatic winding and packaging device for metal wires and an automatic switching device for packaging materials. Background Technology

[0002] Metal wires are susceptible to moisture, wear, deformation, or breakage during transportation, storage, and subsequent processing. Therefore, packaging technology is needed to provide physical protection and fixation. Currently, common packaging methods include PE film wrapping and braided strapping. PE film wrapping typically involves heat fusion or mechanical clamping to wrap the PE film around the wire surface, forming a flexible protective layer, suitable for dust protection and anti-slip of lightweight wires. Braided strapping generally uses high-strength braided straps to wrap around and clamp the wire, providing fixation and tensile strength, suitable for reinforcing heavy-duty or easily deformable wires.

[0003] Existing technologies rely heavily on manual operation, requiring manual feeding, wrapping, melting, or cutting of materials. This is inefficient and prone to inconsistent packaging quality due to human error. If the packaging mode of PE film and woven straps needs to be changed, the machine needs to be stopped for adjustment or parts need to be replaced manually, which is time-consuming and labor-intensive, affecting the continuity of production. It also suffers from problems such as low efficiency, poor precision, and complex material switching, making it difficult to meet the needs of high-efficiency production scenarios. Summary of the Invention

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0035] Please see Figures 1-12This utility model provides an embodiment: a fully automatic winding and packaging device for metal wire and an automatic switching packaging material device, including a material roll rotating mechanism, a PE film loading and unloading mechanism, a PE film moving coil, a braided tape roll, a return mechanism, a braiding moving coil, and a braided tape cutting mechanism mounted on a frame. The PE film loading and unloading mechanism is equipped with a PE film heat-cutting mechanism and a fixture mounting mechanism. The return mechanism is equipped with a braided tape loading and unloading mechanism, and the braided tape loading and unloading mechanism is equipped with a braided tape clamping mechanism. The material roll rotating mechanism drives the material roll to rotate. One end of the braided tape is connected to and wound around the braided tape roll. When the PE film loading and unloading mechanism is started, the braided tape loading and unloading mechanism starts simultaneously. The fixture mounting mechanism is used to grasp and fix the PE film fixture 108. The PE film loading and unloading mechanism drives the fixture mounting mechanism to move and controls the PE film fixture 108 to move closer to or away from the PE film moving coil. When the PE film fixture 108 moves until it connects with the PE film moving ring, the fixture installation mechanism releases the PE film fixture 108, and the PE film hot-cutting mechanism is used to disconnect the PE film; the return mechanism is used to drive the braided belt loading and unloading mechanism to move, the braided belt clamping mechanism is used to fix one end of the braided belt, and the braided belt loading and unloading mechanism is used to drive the braided belt clamping mechanism to move until one end of the braided belt is moved to the braiding moving ring. The braiding moving ring drives the braided belt to move from the braided belt roll to the material roll through friction. When the braided belt moves to the preset value, the braided belt cutting mechanism is used to disconnect the braided belt; this utility model integrates two packaging modules, PE film and braided belt, together. According to the usage needs, a certain packaging module can be selected and switched to operate to package the material roll on the material roll rotating mechanism. The whole process is automated, and the PE film (packaging belt) is loaded, packaged, and melted (cut) in sequence.

[0036] Please see Figure 1 and Figure 12 In this embodiment, the roll rotation mechanism includes a support platform 401 mounted on the frame, a motor 402 mounted on the support platform 401, a drive wheel 403 movably connected to the support platform 401, and a positioning roller 404 mounted on the support platform 401. The drive wheel 403 and the positioning roller 404 are arranged in a circumferential array. The drive wheel 403 is connected to the output end of the motor 402. The positioning roller 404 is used to restrict the movement of the roll. The motor 402 is used to drive the drive wheel 403 to rotate. The drive wheel 403 drives the roll to rotate through friction. The roll rotation mechanism is driven by the motor 402 to control the rotation of the drive wheel 403 (power can be output by chain or belt transmission). The rotation of the roll is controlled by the friction between the drive wheel 403 and the roll. At the same time, the positioning roller 404 is used to restrict the roll around and prevent it from moving.

[0037] Please see Figures 1-7In this embodiment, the PE film loading and unloading mechanism includes a fixed column 101 fixedly mounted on the frame, a fixed platform 102 fixedly connected to the fixed column 101, a first cylinder mounting plate 103 fixedly connected to the fixed platform 102, a third cylinder mounting plate 110 fixedly mounted on the first cylinder mounting plate 103, a sensor bracket 117, a loading and unloading cylinder 105 and a blocking cylinder 109 fixedly mounted on the first cylinder mounting plate 103, a PE film hooking cylinder 111 fixedly mounted on the third cylinder mounting plate 110, a hook shaft adjusting plate 114 mounted on the output end of the PE film hooking cylinder 111, and a sensor bracket 117 fixedly connected to the first cylinder mounting plate 103. The hook shaft 112 on the hook shaft adjusting plate 114, the hook return pad 113 fixedly connected to the other end of the hook shaft 112, and the sensor mounted on the sensor bracket 117 are all connected to the hook shaft 112. The hook shaft 112 is movably connected to the PE film heat-cutting mechanism. The jig mounting mechanism is mounted on the output end of the loading and unloading cylinder 105. The loading and unloading cylinder 105 is used to drive the jig mounting mechanism to move closer to or away from the PE film moving ring. The hook PE film cylinder 111 is used to drive the hook return pad 113 to move closer to or away from the PE film heat-cutting mechanism. When the hook return pad 113 moves closer to the PE film heat-cutting mechanism, the hook return pad 113 and the PE film heat-cutting mechanism clamp the PE film. The PE film heat-cutting mechanism includes a mounting plate 114. A heat-setting blade fixing plate 118 is mounted on the first cylinder mounting plate 103, a heat-setting blade mounting plate 115 is fixedly mounted on the heat-setting blade fixing plate 118, and a heat-setting blade component 116 is fixedly mounted on the heat-setting blade mounting plate 115. A material hooking shaft 112 is movably connected to the heat-setting blade fixing plate 118 and the heat-setting blade mounting plate 115. A PE film hooking cylinder 111 drives a hook-back pad 113 to move closer to or away from the heat-setting blade mounting plate 115 via the hook-back shaft 112. When the PE film moving coil rotates to a preset value F1, the PE film falls onto the hook-back shaft 112. When the PE film hooking cylinder 111 drives the hook-back pad 113 to abut against the heat-setting blade mounting plate 115, the PE film is clamped and the heat-setting blade component 116... 6. The PE film is melted; the fixture mounting mechanism includes a second cylinder mounting plate 104 mounted on the output end of the loading and unloading cylinder 105, a gripper cylinder 106 mounted on the second cylinder mounting plate 104, and a fixed claw 107 mounted on the output end of the gripper cylinder 106. The PE film fixture 108 is provided with a shaft hole. The gripper cylinder 106 is used to drive the fixed claw 107 to open or close. When the fixed claw 107 is opened in the shaft hole, the PE film fixture 108 is fixed. The loading and unloading cylinder 105 drives the PE film fixture 108 to be mounted on the PE film moving ring through the fixture mounting mechanism. The PE film moving ring is used to drive the PE film fixture 108 to rotate.After the pneumatic gripper cylinder 106 controls the fixing claw 107 to fix the PE film fixture 108, the loading / unloading cylinder 105 drives the pneumatic gripper cylinder 106 to move, moving the PE film fixture to the loading position (located on the corresponding PE film fixing structure on the frame; the shaft hole on the PE film fixture will be inserted into the fixing structure and fixed with the PE film moving ring; a magnet is set on the PE film moving ring to attract the PE film fixture to prevent it from falling off when the PE film moving ring rotates). At the same time, the hooking PE film cylinder 111 drives the hook shaft adjusting plate 114 to move, so that the hook return pad 113 and the hot knife mounting plate 115 are close together, clamping one end of the PE film. Then, the pneumatic gripper cylinder 106 releases the fixing claw 107 that grips the PE film fixture, the loading / unloading cylinder 105 retracts, and the PE film fixture can now move with the PE film. The PE film rotating coil rotates a certain number of times (preset value F1), the PE film hooking cylinder 111 extends, controlling the hook return pad 113 and the heat-setting blade mounting plate 115 to move away, releasing one end of the clamped PE film. When the PE film is wound sufficiently on the roll (using automated methods such as visual inspection), a sensor on the PE film rotating coil detects a certain number of turns (which can be detected using a speed sensor). The PE film rotating coil decelerates, and the PE film hooking cylinder 111 extends. When the decelerated PE film rotating coil reaches a fixed position (stops rotating), the stretched PE film falls onto the hook shaft 112. At this point, the PE film hooking cylinder 111 retracts, causing the heat-setting blade mounting plate 115 and the hook return pad 113 to approach and clamp the PE film again. The hooked PE film contacts the heat-setting blade 116 and melts.

[0038] Please see Figures 1-2 and Figures 8-11In this embodiment, the return mechanism includes a second telescopic cylinder 213 mounted on the frame, a second floating joint 212 mounted on the output end of the second telescopic cylinder 213, a movable mounting plate 210 mounted on the second floating joint 212, a guide shaft support 214 mounted on the movable mounting plate 210, a braided tape fixing plate 215, and a photoelectric switch 216. The second telescopic cylinder 213 is used to drive the movable mounting plate 210 to move. The braided tape loading and unloading mechanism is mounted on the movable mounting plate 210. The braided tape loading and unloading mechanism includes a fifth cylinder mounting plate 207 mounted on the movable mounting plate 210, a first telescopic cylinder 208 mounted on the fifth cylinder mounting plate 207, and a fixed connection. A first floating connector 206 is connected to the output end of the first telescopic cylinder 208; a connecting plate 205 is fixedly connected to the first floating connector 206; a drag chain 209 is movably connected to the connecting plate 205; a slider 211 is fixedly connected to the connecting plate 205; and a guide rod 217 with one end fixedly connected to the slider 211. The guide rod 217 is movably connected to the movable mounting plate 210. The braided belt clamping mechanism is mounted on the connecting plate 205. The first telescopic cylinder 208 is used to drive the connecting plate 205 to move along the axial direction of the guide rod 217. The braided belt clamping mechanism includes a fourth cylinder mounting plate 201 mounted on the connecting plate 205 and a clamping cylinder 200 mounted on the fourth cylinder mounting plate 201. 2. A clamp fixing plate 203 and a clamping component 204 are installed on the output end of the clamping cylinder 202. The clamping cylinder 202 is used to drive the clamping component 204 to open or close. When the weaving drive coil rotates to the preset value F2, the clamping cylinder 202 drives the clamping component 204 to open. The weaving tape cutting mechanism includes a support 309 installed on the frame, a top block 310 installed on the support 309, a No. 6 cylinder mounting plate 301 installed on the frame, a cutting cylinder 302 installed on the No. 6 cylinder mounting plate 301, and a cutting module installed on the output end of the cutting cylinder 302. The cutting cylinder 302 is used to drive the cutting module to move closer to or away from the top block 310. When the cutting module approaches the top block 310, the braided tape is cut. The cutting module includes a flange bearing mounting plate 303 mounted on the output end of the cutter cylinder 302, a flange bearing component 304 mounted on the flange bearing mounting plate 303, a cutter mounting plate 305 mounted on the flange bearing mounting plate 303, a cutter component 306 mounted on the cutter mounting plate 305, a pressure plate 308 movably connected to the flange bearing component 304 via a shaft column, and a spring 307 installed between the pressure plate 308 and the flange bearing mounting plate 303. The cutter cylinder 302 is used to drive the cutter component 306 to approach or move away from the top block 310. When the pressure plate 308 abuts against the top block 310, the spring 307 is compressed and contracted.After the clamp 204 re-clamps the braided tape, a certain amount of braided tape is stored on the braiding drive coil. At this time, the cutter 306, under the control of the cutter cylinder 302, descends to cut the braided tape. As the cutter 306 descends, the pressure plate 308 first contacts the top block 310. Through the compression of the spring 307, the pressure plate 308 and the top block 310 clamp the braided tape, which facilitates the cutter 306 in cutting the braided tape. After the braided tape is cut, the clamp 204 is retracted directly by the cutter cylinder 302, without hindering the rotation of the braiding drive coil for packaging.

[0039] Working principle: When the PE film roll needs to be wound, the PE film moving coil will stop rotating in advance. After the PE film moving coil stops, the loading and unloading cylinder 105 will drive the PE film fixture fixed by the fixing claw 107 and the claw cylinder 106 to move to the loading position. At this time, the shaft hole on the PE film fixture will be inserted into the corresponding PE film fixing structure on the frame and fixed with the PE film moving coil. When the PE film fixture is inserted into the fixing structure, one end of the PE film is still clamped between the hot knife mounting plate 115 and the hook return pad 113 (the hook PE film cylinder 111 drives the hook shaft adjusting plate 11...). 4. Move the hook back pad 113 and the hot knife mounting plate 115 closer together to clamp one end of the PE film. Then, the air gripper cylinder 106 will release the fixing claw 107 that grips the PE film fixture. Then, the loading and unloading cylinder 105 will retract, causing the PE film fixture to rotate with the PE film moving ring. After the PE film moving ring rotates a certain number of times (preset value F1), the hook PE film cylinder 111 will extend. Through the hook shaft adjusting plate 114 and the hook shaft 112, the hook back pad 113 will be moved away from the hot knife mounting plate 115. This will release the clamped PE film head without affecting the packaging process. After the PE film is wound enough on the roll, the sensor detects and identifies a certain number of turns by the sensing block on the PE film moving coil. The PE film moving coil then decelerates. At this time, the hooking PE film cylinder 111 extends completely. When the decelerated PE film moving coil returns to the fixed position, the stretched PE film falls onto the hooking shaft 112. Then, the hooking PE film cylinder 111 is controlled to retract, and the hot knife mounting plate 115 and the hook return pad 113 approach and clamp the PE film again. The hooked PE film contacts the hot knife piece 116 and melts, so that one end of the PE film is attached as the roll rotates, and the other end is between the hot knife mounting plate 115 and the hook return pad 113, which facilitates the next automatic loading and unloading of the PE film jig 108.

[0040] When the material roll needs to be wound with braided tape, clamp 204 holds the braided tape. When the material roll needs to be packaged, telescopic cylinder 208 extends, driving the braided tape through from under the cutter 306 until it reaches the inside of the braiding drive ring. At this time, the braiding drive ring rotates, and the transition wheel on the braiding drive ring presses against the braided tape, moving the braided tape through rotational friction. Because one end of the braided tape is held by clamp 204 and the other end is connected to the braided tape roll, the braided tape is pulled on the material roll for packaging. The braided tape roll is pulled and rotated. After the braiding drive ring rotates a certain number of times (preset value F2), the braided tape wraps one end of the material roll. At the same time, some braided tape will also be stored (due to frictional contact) on the braiding drive ring. The clamping cylinder 202 controls the clamp 204 to release the braided tape. While not hindering the rotation of the braiding drive coil for packaging, the second telescopic cylinder 213 drives the clamp 204 to move and disengage from the braided tape. At this time, the clamp 204 is in the open state. When the second telescopic cylinder 213 retracts, it will drive the clamp 204 to move backward. The clamping cylinder 202 controls the clamp 204 to clamp the braided tape above and below. At this time, the cutting cylinder 302 controls the cutting blade 306 to move. With the help of the top block 310, the braided tape will be cut. After cutting, the braiding drive coil will start to rotate rapidly again. Because there is braided tape on the braiding drive coil, packaging will continue. The braided tape clamping mechanism and the braided tape cutting mechanism will return to the unpackaged state.
