Description

Technical Field

[0001] This application relates to the field of plastic film production technology, and in particular to a take-up roller disassembly mechanism for a plastic film processing equipment. Background Technology

[0002] Plastic film processing refers to the process of manufacturing films from plastic materials using various processing methods. These films are widely used in packaging, construction, agriculture, electronics, and many other industries. The main methods of plastic film processing include extrusion, blow molding, and stretching. Many take-up rollers are used in plastic film processing to control the winding and unwinding of the film.

[0003] The existing take-up roller disassembly mechanism includes a main body, a lifting unit located at the upper end of the main body, and a moving unit located on one side of the main body and extending into the interior of the main body. The lifting unit includes a support base, a first shift seat, a lifting arm, an arc-shaped groove, a sliding rod, a drive motor, a threaded rod, and gears. It achieves the function of disassembling the take-up roller by setting up the lifting unit. The rotation of the drive motor causes the threaded rod to rotate, which in turn moves the first shift seat. The upward movement of the first shift seat causes the lifting arm to move upward, bringing the arc-shaped groove into contact with the bottom end of the take-up roller. The upward movement of the lifting arm then moves the take-up roller upward, separating it from the processing equipment, thereby achieving the functions of lifting and disassembling the take-up roller.

[0004] However, in actual use, the width of the roller-taking mechanism is a fixed design width. This causes the roller to tilt when disassembling the wider roller, resulting in the roller falling off. Therefore, this needs to be improved. Utility Model Content

[0005] To improve the practicality of the take-up roller disassembly mechanism, this application provides a take-up roller disassembly mechanism for a plastic film processing equipment.

[0006] The technical solution adopted in this application for a plastic film processing equipment's take-up roller disassembly mechanism is as follows:

[0007] A disassembly mechanism for a take-up roller in a plastic film processing equipment includes a base plate and a disassembly mechanism. Two sets of universal wheels are fixedly installed on the bottom surface of the base plate. The disassembly mechanism is located above the base plate and includes a bracket mounted on the upper surface of the base plate. A first motor is fixedly installed on the upper surface of the bracket. A threaded adjusting rod is fixedly installed at the output end of the first motor. A bracket is threadedly connected to the outer surface of the threaded adjusting rod. Two bearing seats are fixedly installed on the upper surface of the bracket. A positive and negative threaded rod is rotatably mounted on the inner rings of the two bearing seats. A second motor is fixedly installed on the front side of one of the bearing seats. The output end of the second motor is fixedly installed to the front end of the positive and negative threaded rod. Two perforated control plates are fixedly installed on the outer surface of the positive and negative threaded rod. Control rods are fixedly installed on the opposite sides of the two perforated control plates. Sliding holes are provided on the front and back sides of the bracket. The opposite ends of the two control rods pass through the two sliding holes and extend to the outside of the sliding holes. A horizontal plate is fixedly installed on the opposite ends of the two control rods. A slot is provided on the upper surface of each horizontal plate.

[0008] By adopting the above technical solution, through the cooperation of a first motor, a threaded adjusting rod, and a bracket, the bracket can drive the horizontal plate to move up and down, allowing the horizontal plate and the slot to lift the guide roller upwards for disassembly. Furthermore, by utilizing the cooperation of a second motor, a positive and negative threaded rod, a perforated control plate, and a control rod, the control rod can drive the horizontal plate to move, causing the two horizontal plates to move away from each other. This allows the horizontal plate to be adjusted according to the width of the guide roller, thereby improving the stability of the guide roller during disassembly and effectively preventing the guide roller from falling off during disassembly.

[0009] Optionally, two guide rods are fixedly installed on the inner top wall of the bracket, and two guide holes are opened on the upper surface of the bracket. The bottom ends of the two guide rods pass through the two guide holes respectively and are fixedly installed on the upper surface of the base plate.

[0010] By adopting the above technical solution, the guide rod and guide hole can limit the bracket and prevent the bracket from shaking during movement.

[0011] Optionally, the bracket has limit holes on both the front and back sides, and each limit hole has a limit rod slidably connected to its inner wall. The ends of the two limit rods that are far apart from each other are fixedly installed to the sides of the two horizontal plates that are close to each other.

[0012] By adopting the above technical solution, the limiting hole and the limiting rod can limit the horizontal plate and prevent the horizontal plate from sliding during use.

[0013] Optionally, an indicator light is fixedly installed on the upper surface of the bracket.

[0014] Optionally, a push handle is fixedly installed on the upper surface of the base plate, and a control panel is fixedly installed on the front of the bracket.

[0015] Optionally, a fixing seat is fixedly installed on both the front and back of the bracket, and the bottom surface of each fixing seat is fixedly installed to the upper surface of the base plate.

[0016] By adopting the above technical solution, the fixing base can reinforce the bracket, increase the stability of the bracket, and prevent the bracket from shaking or loosening.

[0017] Optionally, an arc-shaped plate is fixedly installed on the front and back of each of the horizontal plates, and a limit ring is fixedly installed on the outer surface of the positive and negative threaded rods.

[0018] By adopting the above technical solutions, the arc-shaped plate can increase the contact area with the take-up roller and improve the stability during disassembly; the limiting ring can limit the perforated control plate and prevent the perforated control plate from separating from the positive and negative threaded rods.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. By using a first motor, a threaded adjusting rod, and a bracket, the bracket can move the horizontal plate up and down, allowing the horizontal plate and the slot to lift the guide roller upwards for disassembly. Furthermore, by using a second motor, a positive and negative threaded rod, a perforated control plate, and a control rod, the control rod can move the horizontal plate, causing the two horizontal plates to move away from each other. This allows the horizontal plate to be adjusted according to the width of the guide roller, thereby improving the stability of the guide roller during disassembly and effectively preventing it from falling off.

[0021] 2. In use, push the device below the take-up roller, and start the second motor according to the width of the take-up roller. The second motor drives the positive and negative threaded rods to rotate. During the rotation, the positive and negative threaded rods engage with the threaded connection of the perforated control plate, causing the perforated control plate to control the control rod to move. The control rod drives the horizontal plate to move, adjusting the distance between the horizontal plates. Then start the first motor, which drives the threaded adjusting rod to rotate. The threaded adjusting rod drives the bracket to move upward, causing the bracket to drive the horizontal plate upward through the cooperation of the control rod and the limit rod, so that the slot is locked on the outside of the take-up roller. As the horizontal plate rises, the take-up roller can be disassembled. Attached Figure Description

Two sets of casters 101 are fixedly mounted on the bottom surface of the base plate 1, and a push handle 3 is fixedly mounted on the upper surface of the base plate 1. The base plate 1 can be moved by pushing the push handle 3, and the movement of the base plate 1 causes the disassembly mechanism 2 to move to the location of the take-up roller to be disassembled for disassembly.

[0029] Reference Figure 1 and Figure 2 The disassembly mechanism 2 includes a bracket 201 mounted on the upper surface of the base plate 1. A control panel 5 is fixedly mounted on the front of the bracket 201. Fixing seats 4 are fixedly mounted on both the front and back of the bracket 201. The bottom surface of each fixing seat 4 is fixedly mounted to the upper surface of the base plate 1. The fixing seats 4 can reinforce the bracket 201, increasing its stability and preventing it from shaking or loosening. An indicator light 7 is fixedly mounted on the upper surface of the bracket 201, which displays the working status of the device to facilitate operation by the operator.
