Description

Technical Field

[0001] This utility model relates to the field of film production technology, specifically a winding device for polystyrene film production. Background Technology

[0002] Polystyrene (PS) film is widely used in packaging, printing, and other fields due to its high transparency and strength. In its continuous production process, winding is a crucial step that directly affects the quality of the final product and production efficiency. Currently, the commonly used polystyrene film winding equipment in the industry typically involves the following steps: First, the empty paper core or plastic core for winding is manually placed onto the winding roller of the winding equipment. Then, the winding roller is driven by a motor to rotate and complete the film winding. However, existing equipment has several shortcomings:

[0003] On the one hand, existing devices often have complex methods for fixing the take-up rollers or core tubes. When it is necessary to remove the already wound core tube, the disassembly process is cumbersome and time-consuming. This not only increases the labor intensity of operators but also increases the equipment occupancy time. On the other hand, and more critically, existing polystyrene film winding devices generally lack effective antistatic functions. Polystyrene materials are prone to generating static electricity during friction. The static electricity accumulated during winding can lead to a series of problems: the film easily attracts dust, affecting the cleanliness of the appearance; the interlayer adhesion of the roll material is serious, making subsequent unfolding difficult, reducing dimensional accuracy, and increasing the scrap rate.

[0004] Therefore, there is an urgent need to develop a new type of winding device for polystyrene film production, which aims to solve the two major problems of rapid disassembly and effective static electricity removal. Utility Model Content

[0026] 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.

[0027] like Figure 1-6 As shown, this utility model provides a technical solution: a winding device for polystyrene film production, including a frame 1 and support legs 101, with multiple sets of support legs 101 connected between the frames 1;

[0028] The upper wall of the frame 1 has four sets of installation notches, and a connecting seat 103 is fixedly installed at the installation notch. The upper end of the connecting seat 103 is connected to a support seat 102. Two sets of rotating wheels 104 are rotatably installed inside the support seat 102. A take-up roller 105 is mounted at the notch of the support seat 102. A connector 109 is connected to the right end of the take-up roller 105. A clamping plate 110 is provided at the right end of the connector 109. A clamping plate 111 is provided at the right end of the clamping plate 110.

[0029] Two sets of fixed seats 2 are fixedly connected to the upper wall of the frame 1. The upper wall of the fixed seat 2 is provided with a threaded groove, and a screw 201 is inserted into the threaded groove. The lower end of the screw 201 is connected to a movable block 202. The outer wall of the movable block 202 is provided with a slot, and a second set of take-up rollers 105 is inserted into the slot. A first set of limiting sleeves 203 is fixedly sleeved on the outside of the second set of take-up rollers 105.

[0030] Two sets of fixed cylinders 204 are fixedly connected to the upper wall of the frame 1. A set of brackets 207 is slidably installed inside the two sets of fixed cylinders 204. A set of antistatic bars 208 is installed inside the two sets of brackets 207. A second base plate 211 is fixedly connected to the right wall of the frame 1. Two sets of high voltage generators 210 are installed on the upper end of the second base plate 211. The two sets of high voltage generators 210 are connected to the two sets of antistatic bars 208 through connecting lines 209.

[0031] Based on the overall structure of the device, the winding roller 105 or core tube can be fixed and disassembled more conveniently, significantly shortening the replacement time, reducing the labor intensity of operators, and reducing the equipment occupancy time. At the same time, it integrates an effective anti-static function, which can prevent polystyrene film from accumulating static electricity during the winding process, causing problems such as dust adsorption and interlayer adhesion, ensuring a clean film appearance, facilitating subsequent unfolding, and thus improving the quality of the final product.

[0032] like Figure 5 As shown, a core 106 is sleeved on the outside of the take-up roller 105 near the support base 102, and the outer wall of the take-up roller 105 and the connector 109 are also provided with threaded slots 107. A fixed shaft 108 is installed inside the threaded slots 107, and fixed nuts are provided at both ends of the fixed shaft 108.

[0033] By using the take-up roller 105 and the connector 109 to connect via the fixed shaft 108 and the fixing screw, the installation of the card plate 110 can be facilitated and completed quickly.

[0034] like Figure 5As shown, the left half of the connector 109 is a cylindrical shaft, and the outer wall of the right half of the shaft is threaded.

[0035] By designing the right half of the connector 109 to have threads, it can be rotatably mounted on the connector 109 via the snap-fit ​​plate 110.

[0036] like Figure 3 As shown, the right end of the chuck 111 is connected to the servo motor 112 via a shaft. The right wall of the frame 1 is fixedly connected to the first base plate 113. The upper wall of the first base plate 113 is fixedly connected to the fixing plate. The outer wall of the fixing plate is provided with a slot. The shaft is connected to the output shaft of the servo motor 112 via the slot. A brake is installed on the motor output shaft of the servo motor 112.

[0037] By connecting the servo motor 112 to the shaft and the chuck 111, it is convenient to drive the rotation of the chuck 111 using the servo motor 112. At the same time, a brake is installed to stop the motor in time, preventing the core 106 from continuing to rotate due to inertia and causing the winding to become loose.

[0038] like Figure 6 As shown, the upper half of the bracket 207 is a ring, and the lower half of the bracket 207 is a sliding tube. Multiple sets of limiting grooves 205 are equidistantly provided on the outer walls of the fixed cylinder 204 and the sliding tube of the bracket 207. A locking block 206 is inserted into the inside of the limiting groove 205.

[0039] Height adjustment is achieved by sliding the bracket 207 inside the fixed cylinder 204, and then fixing it by the locking block 206.

[0040] like Figure 2 As shown, two sets of limiting seats are fixedly installed on the upper wall of the frame 1, and a third set of take-up rollers 105 are inserted between the two sets of limiting seats. A second set of limiting cylinders 203 are sleeved on the outside of the third set of take-up rollers 105.

[0041] By installing a second set of limiting cylinders 203 on the upper end of the frame 1, the film can be squeezed. In combination with the first set of limiting cylinders 203, the angle of the film during winding can be adjusted so that the film is tilted during winding, so that the film is subjected to force as much as possible, thus tightening the film.

[0042] Working Principle: This device can wind up film. Before winding, the core 106 is inserted into the outside of the winding roller 105. Then, the core 106 and the winding roller 105 are fixed with screws. The fixing method of the core 106 and the winding roller 105 is a conventional technology and will not be described in detail here. Then, the winding roller 105 is placed on the upper end of the support base 102. The left end of the winding roller 105 is connected to the clamping plate 110 through the connector 109. Then, the clamping plate 110 is inserted into the clamping plate 111. Next, the servo motor 112 is turned on. After the servo motor 112 is powered on, it will drive the shaft to rotate through the output shaft and coupling. The shaft is connected to the clamping plate 111, which will then drive the clamping plate 111 to rotate. Because the clamping plate 110 is inserted into the clamping plate 111, the clamping plate 111 will drive the clamping plate 110 and the winding roller 105 to rotate. When the core 106 rotates and the clamping disc 111 drives the clamping disc 110 to rotate, due to the influence of centrifugal force and the fixation of multiple sets of insert rods, the clamping disc 110 will basically not fall off during one winding. When the core 106 rotates, it winds the film. The film will first pass around the lower end of the second set of limiting cylinders 203 through the production line, and then around the upper end of the first set of limiting cylinders 203 before finally winding. When adjusting the distance between the two sets of antistatic bars 208 and the film, it should be kept between 10 cm and 15 cm. In this way, the high voltage generator 210 generates high voltage DC through the boost and rectification circuit to supply the antistatic bars 208. The antistatic bars 208 use the high voltage electric field to induce corona discharge, ionizing the air into positive and negative ions, thereby neutralizing the static electricity on the surface of the object. The removal of static electricity will achieve the best effect, making the wound film cleaner and improving the quality of the product.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
