Description

Technical Field

[0001] This utility model relates to the field of double-sided tape production technology, and more specifically, to a bonding device for double-sided tape production. Background Technology

[0002] In the production of double-sided tape, precisely and firmly bonding the tape to the release paper is a crucial step, which typically requires specialized bonding equipment. Existing bonding equipment generally uses pressure rollers to apply pressure, but traditional pressure rollers are often fixed to the main body of the equipment (bolted) and lack protective structures. Because double-sided tape is adhesive, adhesive residue easily remains on the pressure roller surface during bonding, and disassembling the rollers is difficult (requiring the removal of multiple bolts or tools), leading to time-consuming and labor-intensive cleaning, thus impacting production efficiency. Therefore, we have made improvements and proposed a bonding device for double-sided tape production. Utility Model Content

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] For an example, please refer to... Figures 1-4 A bonding device for producing double-sided tape includes two rotating shafts 1. Each rotating shaft 1 has a pressure roller 101 fixedly fitted on its outer surface. A first sleeve 2 is fitted on the outer surface of the rotating shaft 1. An external threaded tube 201 is fixedly connected to one end of the first sleeve 2 near the pressure roller 101. A protective sleeve 202 is fitted on the outer surface of the pressure roller 101. A threaded groove 203 is provided on the inner wall of the protective sleeve 202 near the end of the first sleeve 2, and the threaded groove 203 is threadedly connected to the outer surface of the external threaded tube 201. The protective sleeve 202 isolates the pressure roller 101. The protective sleeve 202 is connected to the external threaded tube 201 by means of the threaded groove 203, which makes the installation and removal of the protective sleeve 202 convenient. When cleaning the residual colloid, the protective sleeve 202 can be removed and cleaned separately. Compared with the traditional method of directly cleaning the pressure roller 101, this application is more convenient and efficient.

[0020] The tightening direction of the threaded groove 203 and the external threaded tube 201 is the same as the rotation direction of the pressure roller 101 and the protective sleeve 202 during operation.

[0021] Furthermore, a handle 204 is fixedly connected to the end of the protective sleeve 202 away from the first sleeve 2, and the handle 204 is designed to facilitate manual rotation of the protective sleeve 202.

[0022] Furthermore, a first support plate 3 is provided between the two pressure rollers 101, and a second support plate 307 is fixedly connected to the bottom of the first support plate 3. A groove 301 is provided on the first support plate 3, and the rotating shaft 1 passes through the groove 301. The groove 301 is provided to prevent the first support plate 3 from affecting the rotating shaft 1.

[0023] Furthermore, a slide rail 303 and a fixed seat 302 are installed on the top of the second support plate 307. A slider 304 is slidably connected to the fixed seat 302. A first support seat 305 is installed on the top of both the slider 304 and the fixed seat 302. A bearing seat 306 is provided on the side of the two first support seats 305 that are close to each other. The bearing seat 306 is connected to the rotating shaft 1 through a bearing. That is, the two rotating shafts 1 provided in this application, one of which is fixed in position, and the other can move horizontally to adjust the distance between the two protective sleeves 202.

[0024] Furthermore, the rotating shaft 1 is provided with two slots, and each slot is fitted with a C-shaped retaining ring 5. The two C-shaped retaining rings 5 ​​are located on both sides of the bearing on the bearing housing 306. The C-shaped retaining rings 5 ​​are existing components, and they cooperate with the slots to limit the connection between the bearing and the rotating shaft 1, so as to prevent the rotating shaft 1 from detaching from the bearing in the bearing housing 306.

[0025] Furthermore, a support member is provided on the outer surface of the rotating shaft 1, and the support member is located in the slide groove 301. The support member includes a second sleeve 4 sleeved on the outer surface of the rotating shaft 1, and a third sleeve 401 is sleeved on the outside of the second sleeve 4 through a bearing. The outer surface of the third sleeve 401 is in rolling connection with the inner wall of the slide groove 301 to support the rotating shaft 1 and improve the stability of the rotating shaft 1.

[0026] Furthermore, a connecting plate 309 is installed on the side of the first support seat 305 connected to the slider 304, and the connecting plate 309 has a through hole; a second mounting seat 310 is installed on the top of the second support plate 307, and a hydraulic cylinder 311 is installed on the second mounting seat 310. The front end of the piston rod of the hydraulic cylinder 311 is threaded, and two nuts are threadedly connected to the front end of the piston rod of the hydraulic cylinder 311. The two nuts are located on both sides of the connecting plate 309. The hydraulic cylinder 311 can drive the first support seat 305 above the slider 304 to move through the connecting plate 309, thereby realizing the adjustment of the distance between the two protective sleeves 202.

[0027] Furthermore, the second support plate 307 is provided with a plurality of mounting holes 308, which are provided for bolts to pass through when the present application is installed on a support object.

[0028] The pressure roller 101 is welded to the rotating shaft 1. The first sleeve 2 and the second sleeve 4 are both connected to the rotating shaft 1 by bolts. The rotating shaft 1 is provided with a screw hole for bolt connection. The external threaded tube 201 is welded to the first sleeve 2. The protective sleeve 202 is welded to the handle 204. The first support plate 3 is welded together with the second support plate 307. The fixed seat 302 is welded onto the second support plate 307. The slide rail 303 is bolted onto the second support plate 307. The first support seat 305 is connected to the fixed seat 302 and the slider 304 by bolts. The bearing seat 306 is bolted onto the first support seat 305. The second mounting seat 310 is bolted to the second support plate 307 and the hydraulic cylinder 311. The connecting plate 309 is welded together with the corresponding first support seat 305.

[0029] In use, the hydraulic cylinder 311 can drive the first support seat 305 above the slider 304 to move through the connecting plate 309. When the first support seat 305 moves, it drives the bearing seat 306 on it to move, thereby driving the rotating shaft 1 to move. The distance between the two protective sleeves 202 is adjusted according to the actual situation. When the double-sided adhesive and the release paper pass through the two protective sleeves 202, they are pressed together by the two protective sleeves 202. When cleaning the protective sleeve 202, turn the handle 204 to make the handle 204 drive the protective sleeve 202 to rotate, so that the threaded groove 203 is separated from the external threaded tube 201. Then pull the handle 204 to remove the protective sleeve 202 from the outer surface of the pressure roller 101. When installing, put the protective sleeve 202 on the outer surface of the pressure roller 101 and rotate the protective sleeve 202 to make the threaded groove 203 and the external threaded tube 201 threaded together.
