Description

TECHNICAL FIELD

[0001] The present application relates to the field of resin film production, and particularly relates to a resin film production equipment. BACKGROUND

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the technical scheme provided by the embodiments of the present application has at least the following beneficial effects:

[0022] In operation, the resin film production equipment of this application conveys resin material to the rear end via guide rollers. When passing through the gap, a scraper removes excess resin material exceeding the gap width, allowing the resin material to be conveyed to the coating mechanism at a preset thickness. Finally, the coating mechanism coats the resin material onto release paper for subsequent drying and winding processes. The scraper mechanism can adjust the gap size. Specifically, the operator controls the rotation of the operating shaft, which in turn drives the worm gear mechanism to rotate, thereby rotating the turbine. Since the turbine is connected to a lead screw via a threaded hole, and the lead screw is connected to the scraper, and the scraper is limited by the guide rail and cannot rotate, the lead screw can drive the scraper to move up and down during the turbine's rotation, changing the gap size. Because the scraper is controlled by at least two evenly distributed lead screws, and the worms of each turbine mechanism are simultaneously coaxially connected to the operating shaft, the worms, turbines, and lead screws can move synchronously when the operating shaft rotates. This ensures smooth lifting and lowering of the scraper, reducing the risk of the scraper tilting due to different movement speeds or unbalanced forces in different areas, further improving the accuracy of gap adjustment and the uniformity of resin film thickness adjustment.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0031] 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, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Currently, resin film production processes are mainly divided into two categories: manual operation and mechanized production. Manual production relies on manual application of liquid resin evenly onto the carrier surface, followed by manual cutting and winding of the dried and cured resin film for subsequent applications. While flexible, this method significantly limits production efficiency, and the uniformity of resin film thickness is highly dependent on the operator's skill and experience, making it difficult to ensure product consistency. In contrast, mechanized production relies on coating machines to produce resin films. Although this greatly improves production efficiency, insufficient precision or improper parameter adjustment of the coating machine can also lead to uneven resin film thickness, affecting product quality.

[0033] To address the aforementioned technical problems, this embodiment provides a resin film production equipment.

[0034] The resin film production equipment provided in this embodiment includes: a guide roller 1, a doctor blade mechanism 2, a coating mechanism 3, and a frame 4.

[0035] The guide roller 1 is rotatably mounted on the frame 4 and is used to convey resin material to the rear end.

[0036] The scraper mechanism 2 is used to control the thickness of the resin film, which comprises a scraper 21, a lead screw 22, an operating shaft 23, a worm gear mechanism 24 and a gantry 25 fixedly connected with the rack 4 and provided with vertical guide rails 26, the scraper 21 is slidably connected with the guide rails 26 and is arranged in parallel above the material guide roller 1, a gap for passing the resin material is formed between the scraper 21 and the material guide roller 1, the operating shaft 23 is rotatably arranged on the gantry 25, the number of the lead screws 22 is at least two, each of which is connected with the scraper 21 and is uniformly arranged along the length direction of the scraper 21, the worm gear mechanisms 24 are installed on the gantry 25 and are provided with two, the worm gears 242 of the two worm gear mechanisms 24 are coaxially and fixedly connected with the operating shaft 23, and the worms 241 of the two worm gear mechanisms 24 are provided with threaded holes and are respectively connected with the two lead screws 22 through the threaded holes.

[0037] The coating mechanism 3 is connected with the rack 4 and is located at the rear end of the material guide roller 1, and is used to coat the resin material output from the gap on the release paper.

[0038] When the resin film production equipment works, the resin material is conveyed to the rear end through the material guide roller 1, when passing through the gap, the scraper 21 scrapes off the excess resin material beyond the gap width, so that the resin material is conveyed to the coating mechanism 3 according to the preset thickness, and finally the resin material is coated on the release paper by the coating mechanism 3, so as to carry out subsequent drying, winding and other processes. Among them, the scraper mechanism 2 can adjust the size of the gap. Specifically, the operator controls the rotation of the operating shaft 23 to drive the rotation of the worm gear 242 of the worm gear mechanism 24, and then drives the rotation of the worm 241. Since the worm 241 is connected with the lead screw 22 through the threaded hole, the lead screw 22 is connected with the scraper 21, and the scraper 21 is limited by the guide rail 26 and cannot rotate, so that the lead screw 22 can drive the scraper 21 to move up and down during the rotation of the worm 241, thereby changing the size of the gap. Since the scraper 21 is controlled by at least two uniformly arranged lead screws 22, and the worm gears 242 of the worm gear mechanisms 24 are coaxially connected with the operating shaft 23 at the same time, when the operating shaft 23 rotates, each worm gear 242, worm 241 and lead screw 22 can act synchronously, thereby stably driving the scraper 21 to rise and fall, reducing the risk of tilting of the scraper 21 due to different moving speeds or unbalanced forces in different regions, and further improving the accuracy of gap adjustment and the uniformity of resin film thickness adjustment.

[0039] In an embodiment in which the operation shaft 23 is rotatably arranged on the gantry 25, the worm gear mechanism 24 further comprises a mounting base 243 fixed on the gantry 25 as a support structure of the worm gear mechanism 24. The mounting base 243 is firmly fixed on the gantry 25 by bolts or other fastening devices to ensure the stability and reliability of the entire mechanism. The mounting base 243 is internally provided with a bearing seat for supporting the operation shaft 23, and the operation shaft 23 is connected with the bearing seat through a bearing. Meanwhile, the mounting base 243 is internally provided with mounting grooves for the worm 241 and the worm gear 242, and the worm 241 and the worm gear 242 are rotatably arranged in the mounting grooves of the mounting base 243 through existing ways such as shaft fitting or wheel groove cooperation.

[0040] In an embodiment in which the lead screw 22 is connected with the scraper 21, the lower end of the lead screw 22 is provided with a connecting head 27 fixedly connected with the scraper 21. The connecting head 27 is provided with a clamping groove and is clamped at the upper end of the scraper 21 to limit the movement of the connecting head 27 and the scraper 21 in the width direction of the scraper 21. The width of the clamping groove is slightly smaller than the width of the upper end of the scraper 21 to ensure that the scraper 21 can be tightly clamped in the clamping groove. The two sides of the clamping groove are designed with protruding limiting blocks for limiting the movement of the scraper 21 in the width direction to ensure that the scraper 21 will not shake or deviate during work. When the scraper 21 is worn or needs to be replaced, the fastening device of the connecting head 27 is only loosened, and the scraper 21 can be easily taken out from the clamping groove and replaced with a new scraper 21.

[0041] In order to conveniently control the rotation of the operation shaft 23, the operation shaft 23 extends to both sides of the rack 4 and is respectively provided with a hand wheel 28 for controlling the rotation of the operation shaft 23. The operator can control the rotation of the operation shaft 23 by rotating the hand wheel 28 to adjust the transmission ratio and output torque of the worm gear mechanism 24. The rotation direction and angle of the hand wheel 28 can be displayed through a scale disc or an indicator for the operator to make accurate adjustment.

[0042] In some embodiments, the resin film production device further comprises a guide plate 5 arranged on the rack 4 and located at the front end of the guide roller 1. The guide plate 5 and the guide roller 1 form a material groove for placing resin material therebetween. The guide plate 5 is designed in an inclined shape with the front end being higher and the rear end being lower to facilitate the sliding of the resin material into the material groove from the front end.

[0043] Further, in order to adjust the width of the material bin, the guide plate 5 and the rack 4 are connected through a slide rail 6 extending along the width direction of the material groove. The slide rail 6 is provided with slide grooves on both sides for cooperating with the slide blocks on the guide plate 5 to realize the movement and positioning of the guide plate 5. The rack 4 is provided with a pitch adjusting mechanism 7 for controlling the movement of the guide plate 5 along the slide rail 6.

[0044] The distance adjusting mechanism 7 can use an existing distance adjusting mechanism 7. For example, the distance adjusting mechanism 7 includes a screw rod 71, a handle 72, and a nut 73. The nut 73 is connected to the guide plate 5. The screw rod 71 is connected to the nut 73 and is connected to the frame 4 through a rotating seat, so that it can rotate relative to the frame 4. The handle 72 is connected to the screw rod 71 and is used to control the rotation of the screw rod 71. When adjusting the position and width of the guide plate 5, first loosen the fastening device of the distance adjusting mechanism 7, then rotate the handle 72 to control the lifting of the screw rod 71, so that the guide plate 5 moves along the slide rail 6 to the desired position. After moving to the desired position, tighten the fastening device of the distance adjusting mechanism 7 again to fix the guide plate 5 on the frame 4.

[0045] In one embodiment of the coating mechanism 3, the coating mechanism 3 includes a feeding roller 31, a release paper roller 32, and an intermediate roller 33. The release paper roller 32 is used to transport the release paper, so that the release paper passes through the intermediate roller 33 and the feeding roller 31 in turn. The release paper serves as a carrier, its surface is smooth, and it is easy for resin materials to adhere and peel off. In the production process, the release paper is continuously pulled out from the release paper roller 32, providing a stable base for subsequent resin coating. The intermediate roller 33 is located between the release paper roller 32 and the feeding roller 31, playing a role of connecting the two. When the release paper is pulled out from the release paper roller 32, it will first pass through the intermediate roller 33. Here, the intermediate roller 33 can slightly flatten or adjust the tension of the release paper to ensure that the release paper is in the best state before entering the feeding roller 31. In addition, the intermediate roller 33 can also pre-coat or pre-heat the resin material as needed to improve the coating effect. The feeding roller 31 is used to transport the release paper and resin material to the rear end. During the transportation process, the resin material is evenly coated on the surface of the release paper. The speed and pressure parameters of the feeding roller 31 can be adjusted according to actual production needs to achieve the best coating effect.

[0046] It can be understood that the coating mechanism 3 can also use existing mechanisms for coating resin films.

[0047] In order to facilitate the subsequent drying process, the resin film production equipment also includes a drying table 7 located at the rear end of the coating mechanism 3. The drying table 7 is placed on the ground and is used to receive the release paper and resin material output by the coating mechanism 3. In the actual production process, the working process is as follows: first, the release paper is continuously pulled out from the release paper roller 32 and is pre-processed by the intermediate roller 33. Then, the resin material is coated on the surface of the release paper and is transported to the rear end of the drying table 7 by the rotation of the feeding roller 31. Subsequently, the resin material gradually solidifies to form a resin film. Finally, after processes such as cutting and winding, the finished resin film is obtained.

[0048] It can be understood that the guide roller 1, the feeding roller 31, and the release paper roller 32 can be driven to rotate by a motor.

[0049] The above merely provides the optional embodiments of the present application, but does not intend to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
