Description

Technical Field

[0001] This utility model relates to the field of tape production technology, specifically to an interval coating device for tape production. Background Technology

[0002] In the production process of adhesive tape, adhesive coating is a crucial step that directly affects the tape's adhesion, performance, and applicable scenarios. With the diversification of industrial production, the demand for adhesive tape is no longer limited to conventional types with overall adhesive coating. Interval-coated tapes, due to their advantages such as reducing adhesion area and lowering usage costs in specific scenarios, are experiencing increasing market demand.

[0003] According to announcement number CN 210546007 U, an interval gluing device for tape production includes a support frame. Two sets of fixing plates are fixedly installed on the upper end of the support frame. A first conveying component and a second conveying component are respectively arranged on both sides of the support frame. The first conveying component and the second conveying component each include a first roller and a second roller.

[0004] This device, through its toothed friction blocks, increases the friction between the rolling column and the conveyor belt, preventing insufficient friction that could prevent the belt from driving the rolling column to rotate. The baffles and extrusion blocks ensure the conveyor belt passes smoothly through the conveyor assembly for adhesive application, avoiding excessive compression. The collection pool and trough collect residual adhesive after application and also collect spilled adhesive during application, improving its future applicability. However, the device lacks a tension adjustment mechanism for the conveyor belt, which can cause wrinkles in the belt during application, resulting in uneven adhesive application.

[0033] Example 2

[0034] Please see Figure 4-5 Furthermore, based on Example 1, a glue application mechanism 6 was obtained.

[0035] The adhesive application mechanism 6 includes a third fixed frame 61, which is fixedly connected to the top of the base 1. A housing 62 is fixedly connected to the top of the third fixed frame 61. An adhesive injection tube 63 is fixedly connected to the top of the housing 62 near the front. A pump body 64 is fixedly connected to the front of the housing 62. An adhesive inlet tube 65 is fixedly connected to the input end of the pump body 64. An adhesive outlet tube 66 is fixedly connected to the output end of the pump body 64. A servo motor 67 is fixedly connected to the surface of the third fixed frame 61 near the top. A rotating cylinder 68 is fixedly connected to the output end of the servo motor 67. Four adhesive outlets 611 are equidistantly opened on the outer wall of the rotating cylinder 68. Four silicone coating plates 69 are fixedly connected to the outer wall of the rotating cylinder 68. A fixed shaft 612 is rotatably connected to the front of the inner wall of the third fixed frame 61 near the top. A rotary joint 613 is fixedly connected to the rear end of the fixed shaft 612. A connecting pipe 614 is fixedly connected to the surface of the rotary joint 613. An L-shaped block 615 is fixedly connected to the front of the inner wall of the fixed frame.

[0036] The bottom front of the box 62 has a hole that matches the dispensing tube 66, and the dispensing tube 66 passes through the surface and is fixedly connected to the hole.

[0037] The third fixing bracket 61 has a hole on the top front that matches the dispensing tube 66, and the surface of the dispensing tube 66 is penetrated and fixedly connected to the hole. The other end of the dispensing tube 66 is fixedly connected to the top of the connecting tube 614.

[0038] The rotating cylinder 68 has a hole on its front side that matches the rear end of the rotary joint 613, and the surface of the rotary joint 613 is fixedly connected to the hole. The other end of the L block 615 is fixedly connected to the surface of the rotary joint 613 to support the rotary joint 613.

[0039] In actual operation, when this device is used, the adjusting mechanism 5 plays an important role in the conveyor belt transmission process. When the thickness and other specifications of the conveyor belt change, the conveyor belt will exert different pressures on the second roller 514. The pressure is transmitted to the fourth fixed plate 513, which in turn drives the second hinge frame 511 to slide up and down on the surface of the second guide rod 59. The movement of the second hinge frame 511 is transmitted to the first hinge frame 56 through the hinge rod 512, causing the first hinge frame 56 to drive the slider 54 to slide on the surface of the first guide rod 52. At this time, the spring 55 between the first fixed plate 53 and the slider 54 will deform due to the sliding of the slider 54, generating a reverse elastic force, thereby driving the components to move in the opposite direction. Finally, the second roller 514 is automatically adjusted to a position that matches the specifications of the conveyor belt, ensuring that the conveyor belt is always transmitted in a stable state.

[0040] The glue application mechanism 6 is responsible for completing the interval glue application operation. It injects glue into the box 62 through the glue injection pipe 63, starts the pump body 64, and the glue is sucked into the pump body 64 through the glue inlet pipe 65. Then it is delivered to the connecting pipe 614 through the glue outlet pipe 66 and enters the rotating cylinder 68 through the rotary joint 613. At the same time, the servo motor 67 is started, and the servo motor 67 drives the rotating cylinder 68 to rotate. The silicone plate 69 on the outer wall of the rotating cylinder 68 rotates together with it. When the glue outlet 611 on the rotating drum 68 aligns with the position of the silicone coating plate 69, glue flows out from the glue outlet 611 and adheres to the silicone coating plate 69. As the rotating drum 68 continues to rotate, the silicone coating plate 69 comes into contact with the conveying tape, completing the glue application to the tape. Due to the precise control of the servo motor 67 and the equidistant setting of the silicone coating plates 69, the tape is applied at intervals. Throughout the process, the L block 615 provides stable support for the rotary joint 613, ensuring that the rotary joint 613 works normally when the rotating drum 68 rotates, ensuring that the glue can continuously and stably enter the rotating drum 68, and ensuring the smooth progress of the glue application operation.
