Description

Technical Field

[0001] This utility model relates to the field of foam tape production technology, and in particular to a coating device for foam tape production. Background Technology

[0002] In the production of foam tape, lamination is a crucial process. Its function is to cover the adhesive surface of the foam tape with a protective release film to prevent contamination, sticking, or loss of tack, thus ensuring the product's performance during transportation, storage, and subsequent use. One of the core components of the lamination equipment is the unwinding mechanism used to release the protective film.

[0003] Currently, the unwinding mechanism of laminating equipment commonly used in the industry is a single-station unwinding type. When a roll of protective film is used up or the product specification needs to be changed, the entire machine must be stopped for a long time. The operator must remove the used paper core from the unwinding shaft, then hoist the new film roll onto the unwinding shaft, and finally restart the equipment. Because each roll change means a complete interruption of the production line for a long time, the entire process is time-consuming, resulting in a decrease in the overall efficiency of the laminating equipment. Utility Model Content

[0004] Therefore, it is necessary to provide a laminating device for foam tape production to address the problem that each roll change means a long and complete interruption of the production line, resulting in a long process time and a decrease in the overall efficiency of the laminating device.

[0005] A laminating device for producing foam tape includes: a production frame, a film changing mechanism, and a conveying mechanism disposed inside the production frame; The film changing mechanism includes a drive disk, a mounting disk, a feed roll, a feed roll, and a switching component for switching the feed roll and the feed roll; The drive disk and the mounting disk are each provided in two sets. The two sets of mounting disks are fixedly installed on the corresponding surfaces of the two sets of drive disks. The unloading roll and the loading roll are arranged between the two sets of mounting disks. The two sets of drive disks are rotatably arranged above the production frame.

[0006] In one embodiment, the switching component includes a mounting plate, a support plate, a motor, and a limiting module. The mounting plate and the support plate are provided in two sets. The two sets of mounting plates are fixedly mounted on the upper surface of the production frame, and the two sets of support plates are disposed on the upper surface of the corresponding mounting plate. The motor is bolted to the outside of one set of support plates.

[0007] In one embodiment, the two sets of drive discs are rotatably disposed between two sets of support plates via connecting shafts, one set of connecting shafts rotatably passes through the corresponding support plate, and the other set of connecting shafts is keyed to the motor output end.

[0008] In one embodiment, the limiting module includes an extension post and a limiting ball, the extension post being fixedly disposed on the side of a set of support plates, and the limiting ball being fixedly disposed on the side of the extension post near the drive disc.

[0009] In one embodiment, a set of the drive discs has a sliding groove on its side corresponding to the extension post, and a set of the drive discs has a limiting groove on its side corresponding to the limiting ball.

[0010] In one embodiment, the sliding groove and the limiting groove are connected and are located on the upper half of a set of drive discs.

[0011] In one embodiment, both sets of mounting disks have snap-fit ​​covers symmetrically arranged on their outer arc surfaces, and both sides of the four sets of snap-fit ​​covers have extension plates that connect to the drive disk.

[0012] In one embodiment, both the unloading roll and the loading roll are rotatably provided with mounting columns inside, and both sets of mounting discs have mounting grooves on their sides corresponding to the mounting columns.

[0013] In one embodiment, two sets of limiting discs are sleeved on the outer arc surfaces of the two sets of mounting columns, and the unloading roll and the loading roll are respectively located between the corresponding two sets of limiting discs.

[0014] In one embodiment, the unloading roll and the loading roll are rotatably disposed between two sets of mounting discs via mounting columns, and the unloading roll and the loading roll do not contact each other.

[0015] Beneficial effects 1. The above-mentioned laminating device sets up a feed roll and a feed roll between two sets of mounting plates, and sets the two sets of mounting plates between two sets of drive plates. After the feed roll or feed roll is used up, the switching component drives the two sets of drive plates to rotate 180 degrees, thereby switching the angle of the feed roll and the feed roll. This avoids the need to disassemble and replace the feed roll or feed roll, thereby improving the overall efficiency of the laminating device.

[0016] 2. In the above-mentioned coating device, the motor drives the drive disc to rotate. By setting extension columns and limiting balls on the side of the support plate and engaging them in the sliding groove and limiting groove on the side of the drive disc, the rotation of the drive disc is limited, ensuring stability during the switching process of the unloading roll and the loading roll.

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0021] The following is combined Figures 1-5 This invention describes a laminating device for producing foam tape.

[0022] In one embodiment, a laminating device for producing foam tape includes: a production frame 100, a film changing mechanism 200, and a conveying mechanism 300 disposed inside the production frame 100; two sets of mounting discs 202 are symmetrically provided with snap-fit ​​covers 206 on their outer arc surfaces, and extension plates 208 connected to drive discs 201 are provided on both sides of the four sets of snap-fit ​​covers 206; mounting posts 212 are rotatably disposed inside the unloading roll 203 and the loading roll 207, and mounting grooves 213 corresponding to the mounting posts 212 are opened on the sides of the two sets of mounting discs 202; two sets of limiting discs 214 are sleeved on the outer arc surfaces of the two sets of mounting posts 212, and the unloading roll 203 and the loading roll 207 are respectively located between the corresponding two sets of limiting discs 214; the unloading roll 203 and the loading roll 207 are rotatably disposed between the two sets of mounting discs 202 through the mounting posts 212, and the unloading roll 203 and the loading roll 207 do not contact each other; In this embodiment, the mounting post 212 passes through the unloading roll 203 and the loading roll 207. Then, limiting plates 214 are set on both sides of the unloading roll 203 and the loading roll 207 to prevent the unloading roll 203 and the loading roll 207 from moving on the surface of the mounting post 212. Then, the mounting post 212 is inserted into the mounting groove 213 to place the unloading roll 203 and the loading roll 207 on both sides of the two sets of mounting plates 202. Then, the extension plate 208 is used to fasten four sets of snap-fit ​​covers 206 to both sides of the mounting plates 202 to install the unloading roll 203 and the loading roll 207, thereby facilitating the switching between the unloading roll 203 and the loading roll 207.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, the film changing mechanism 200 includes a drive disk 201, a mounting disk 202, a feed roll 203, a feed roll 207, and a switching assembly for switching the feed roll 203 and the feed roll 207; both the drive disk 201 and the mounting disk 202 are provided in two sets, with the two sets of mounting disks 202 fixedly mounted on the corresponding surfaces of the two sets of drive disks 201, and the feed roll 203 and the feed roll 207 disposed between the two sets of mounting disks 202; the two sets of drive disks 201 are rotatably mounted above the production frame 100; the switching assembly includes a mounting plate 204, The support plate 205, motor 210, and limit module are provided. There are two sets of mounting plates 204 and support plates 205. The two sets of mounting plates 204 are fixedly set on the upper surface of the production frame 100. The two sets of support plates 205 are set on the upper surface of the corresponding mounting plates 204, and the motor 210 is bolted to the outside of one set of support plates 205. The two sets of drive discs 201 are rotatably set between the two sets of support plates 205 through connecting shafts. One set of connecting shafts rotatably passes through the corresponding support plate 205, and the other set of connecting shafts is keyed to the output end of the motor 210. In this embodiment, the two sets of drive disks 201 are supported by the mounting plate 204 and the support plate 205 to ensure the stability of the two sets of drive disks 201 and the mounting disk 202 during rotation between the two sets of support plates 205. The motor 210 drives one set of drive disks 201 to rotate through the connecting shaft. The motor 210 has an anti-reverse structure to prevent the drive disks 201 and the mounting disk 202 from rotating when the motor 210 is not running. This drives the unloading roll 203 and the loading roll 207 to rotate 180 degrees, thereby switching the unused unloading roll 203 or the loading roll 207. Then, during the normal operation of the device, the unused unloading roll 203 or the loading roll 207 is switched, thereby improving the overall efficiency of the coating device.

[0024] like Figure 2 , Figure 4 and Figure 5 As shown, the limiting module includes an extension post 209 and a limiting ball 211. The extension post 209 is fixedly disposed on the side of a set of support plates 205, and the limiting ball 211 is fixedly disposed on the side of the extension post 209 near the drive plate 201. A sliding groove 215 corresponding to the extension post 209 is opened on the side of the set of drive plates 201, and a limiting groove 216 corresponding to the limiting ball 211 is opened on the side of the set of drive plates 201. The sliding groove 215 and the limiting groove 216 are connected and disposed, and the sliding groove 215 and the limiting groove 216 are opened in the upper half of the set of drive plates 201. In this embodiment, the size of the limiting ball 211 is larger than the size of the extension column 209. When the drive disk 201 rotates, the extension column 209 rotates along the sliding groove 215, and the limiting ball 211 rotates along the limiting groove 216. The limiting ball 211 prevents the extension column 209 from disengaging from the sliding groove 215, ensuring the stability of the extension column 209 during the sliding process inside the sliding groove 215. Thus, the rotation of the drive disk 201 is limited by the cooperation of the extension column 209 and the limiting ball 211, ensuring the stability when switching between the drive disk 201 and the mounting disk 202.

[0025] Working principle: After the unloading roll 203 or loading roll 207 is used up, the machine is briefly stopped, and then the motor 210 is started to drive the drive disk 201 to rotate, thereby switching the positions of the unloading roll 203 and loading roll 207. At this time, the extension column 209 and the limiting ball 211 are engaged in the sliding groove 215 and the limiting groove 216 to rotate, thereby limiting the switching of the unloading roll 203 and loading roll 207. Then, the replaced unloading roll 203 or loading roll 207 is connected to the laminating device, and then the device is started again. After the device is running, the used unloading roll 203 or loading roll 207 is replaced. Thus, the unloading roll 203 and loading roll 207 can be switched by briefly stopping the device, avoiding the need to disassemble the unloading roll 203 or loading roll 207 for replacement, thereby improving the overall efficiency of the laminating device.

[0026] It should be noted that the motor 210 and other components mentioned above are all devices with relatively mature existing technologies. The specific model can be selected according to actual needs. In addition, the motor 210 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0027] It should be noted that the laminating device in this application can be a foam laminating machine of model XZ-1200, and the film changing mechanism 200 is provided with control components, unwinding components and rewinding components on the side.

[0028] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
