Abstract
Description
Technical Field
[0001] This utility model relates to the field of pearl cotton plastic bag production technology, specifically to a pearl cotton plastic bag production equipment. Background Technology
[0002] In the production process of EPE foam plastic bags, winding is a crucial step. Its function is to neatly wind the finished EPE foam plastic bags onto the winding roller for subsequent storage, transportation and further processing.
[0003] Currently, the industry commonly uses take-up rollers to wind up finished EPE (expanded polyethylene) plastic bags. However, this method has significant drawbacks in actual production. Because existing take-up rollers lack effective limiting structures on their outer sides, it's difficult to precisely constrain the lateral position of the EPE plastic bag as it winds around the roller. As the winding process continues, the EPE plastic bag tends to shift laterally on the take-up roller, resulting in unevenness on both sides of the EPE wrapped around the roller.
[0004] This unevenness can cause a series of problems: on the one hand, it seriously affects the appearance quality of the rolled-up product, failing to meet the requirements of standardized production; on the other hand, the uneven rolls make subsequent handling and stacking difficult, increasing operational complexity and labor intensity. Furthermore, when processing and using the EPE foam bags later, additional time and effort are required for sorting, reducing production efficiency and potentially causing damage to the EPE foam bags due to improper handling during the sorting process, resulting in unnecessary losses. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a production equipment for pearl cotton plastic bags, which solves the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a pearl cotton plastic bag production equipment, comprising a base frame, two support frames, a top plate, two support brackets and a winding roller;
[0007] The two support frames are symmetrically arranged on the upper surface of the base frame. The top plate is installed on the rear side of the support frame. The cross-sectional shape of the side of the top plate is L-shaped. The two support brackets are slidably connected to the outer sides of the two support frames respectively.
[0008] An arc-shaped groove is provided on the upper end face of both of the support frames, and the take-up roller is placed inside the two arc-shaped grooves. A lifting assembly is provided inside the top plate to drive the support frame and the take-up roller to move up and down.
[0009] The top plate is also provided with a limiting component, which includes two guide rails arranged laterally on the inner top wall of the top plate. The two guide rails are arranged in parallel front to back. Two limiting plates are slidably connected to the outside of the guide rails. The limiting plates have U-shaped grooves with missing bottom ends inside. Both limiting plates are sleeved on the outside of the take-up roller.
[0010] An adjustment structure is also provided on the lower surface of the top plate to adjust the distance between the two limiting plates.
[0011] Furthermore, the lifting assembly includes a connecting plate, which is mounted on the two support brackets to connect the two support brackets. A screw is rotatably connected between the top plate and the base frame, and a motor with its output end connected to the screw is mounted on the top of the top plate.
[0012] Corresponding to the screw, a threaded through hole adapted to the screw is provided inside the connecting plate so that the screw is threadedly connected to the connecting plate.
[0013] Furthermore, the adjustment structure includes two mounting plates, which are respectively installed on the left and right sides of the inner top wall of the top plate. The same lead screw is rotatably connected inside the two mounting plates, and the lead screw is threadedly connected to the two limiting plates.
[0014] Furthermore, the outer surface of the lead screw is provided with two threaded grooves, and the thread directions of the two threaded grooves are opposite.
[0015] Furthermore, one of the mounting plates is rotatably connected to a handle, one end of which is fixedly connected to the lead screw.
[0016] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0017] 1. This EPE foam plastic bag production equipment uses adjustable limit plates to precisely limit the EPE foam, effectively preventing lateral deviation during winding. This ensures that the wound EPE foam is neat on both sides, meeting standardized production requirements, improving product appearance quality and the convenience of subsequent processing. The spacing of the limit plates can be quickly adjusted via an adjustable structure, making it suitable for winding EPE foam plastic bags of different widths and reducing adjustment time when switching specifications. Meanwhile, the lifting component shortens the loading and unloading time of the winding roller, improving overall production efficiency.
[0018] 2. This pearl cotton plastic bag production equipment features a lifting component that enables automatic lifting of the winding roller, completely replacing manual handling. This solves the problem of difficult handling caused by the heavy weight of the winding roller, reduces the physical exertion of operators, and avoids safety accidents such as bumps and injuries that may occur during handling.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-3 The pearl cotton plastic bag production equipment in this embodiment includes a base frame 1, two support frames 2, a top plate 3, two support frames 4, a winding roller 5, a lifting assembly 6, and a limiting assembly 7.
[0025] In detail, the two support frames 2 are fixed symmetrically on the upper surface of the base frame 1 to form the support frame of the equipment. The top plate 3 is installed on the rear side of the two support frames 2. Its side cross-section is L-shaped, which serves both as support and installation. The two support brackets 4 are slidably connected to the outside of the two support frames 2 respectively. The upper end face of each bracket is provided with an arc groove. The winding roller 5 is placed in the two arc grooves to realize the bearing of the winding roller 5.
[0026] More specifically, the limiting component 7 is installed on the top plate 3, including two horizontally parallel guide rails 701, with two limiting plates 702 slidably connected to the outside of the guide rails 701. The limiting plates 702 have U-shaped grooves missing at the bottom and are sleeved on the outside of the take-up roller 5. An adjustment structure is also provided on the lower surface of the top plate 3 to adjust the distance between the two limiting plates 702.
[0027] In actual setup, guide rail 701 provides a transverse sliding track for limit plate 702 to ensure smooth movement of limit plate 702; the U-shaped groove of limit plate 702 is sleeved on the outside of take-up roller 5, which forms a rigid constraint on the left and right sides of pearl cotton without affecting the rotation of take-up roller 5, and prevents deviation during take-up.
[0028] The adjustment structure includes two mounting plates 703, which are respectively installed on the left and right sides of the inner top wall of the top plate 3. The same lead screw 704 is rotatably connected inside the two mounting plates 703. The lead screw 704 is threadedly connected to the two limiting plates 702. The outer surface of the lead screw 704 has two threaded grooves, and the thread directions of the two threaded grooves are opposite. A handle 705 is rotatably connected inside one of the mounting plates 703. One end of the handle 705 is fixedly connected to the lead screw 704.
[0029] In actual use, in the adjustment structure, the reverse threads at both ends of the lead screw 704 are connected to the two limit plates 702 respectively. Rotating the handle 705 can drive the two limit plates 702 to move synchronously in opposite directions, quickly adapting to pearl cotton of different widths and ensuring neat winding.
[0030] In addition, the lifting assembly 6 includes a connecting plate 601, which is mounted on two support brackets 4 to connect the two support brackets 4. A screw 602 is rotatably connected between the top plate 3 and the base frame 1. A motor 603 with its output end connected to the screw 602 is installed on the top of the top plate 3. Corresponding to the screw 602, a threaded through hole adapted to the screw 602 is opened in the interior of the connecting plate 601 so that the screw 602 is threadedly connected to the connecting plate 601.
[0031] In actual use, when the motor 603 drives the screw 602 to rotate, the screw 602 engages with the threaded through hole of the connecting plate 601, converting the rotational motion into linear motion, which drives the two support frames 4 to rise and fall synchronously. When it is necessary to install the take-up roller 5, the height of the support frame 4 is lowered, making it easier for the operator to place the take-up roller 5 into the arc groove. After winding is completed, the support frame 4 is lowered again to facilitate the removal of the take-up roller 5. The entire process does not require manual handling of the heavy take-up roller 5, greatly reducing labor intensity and avoiding safety hazards during handling.
[0032] The working principle of the above embodiments is as follows:
[0033] 1. Start the motor 603 of the lifting assembly 6 to drive the support frame 4 to descend to the low position. The operator places the empty take-up roller 5 in the arc groove of the two support frames 4. According to the width of the pearl cotton to be rolled, turn the handle 705 to drive the screw 704 to rotate, so that the two limit plates 702 move towards each other along the guide rail 701 until the distance between the two limit plates 702 is consistent with the width of the pearl cotton, and the limit adjustment is completed. Raise the support frame 4 through the lifting assembly 6 so that the take-up roller 5 is at a suitable take-up height, and fix one end of the pearl cotton on the take-up roller 5.
[0034] 2. Rotate the take-up roller 5, and the pearl cotton is wound on the take-up roller 5. During the winding process, the two limit plates 702 constrain the pearl cotton on the left and right sides to prevent it from deviating and ensure neat winding. If the height of the take-up roller 5 needs to be adjusted during the winding process, it can be finely adjusted through the lifting component 6 to ensure smooth winding. After the winding is completed, stop the winding drive device, lower the support frame 4 to the low position through the lifting component 6, and the operator removes the take-up roller 5 with the pearl cotton wound on it to complete one winding operation.
