Description

Technical Field

[0001] The utility model relates to the technical field of heat-conducting double-sided adhesive tape production, in particular to an adjustable stripping device for double-sided adhesive tape production. Background Art

[0002] Thermally conductive double-sided tape is made from acrylic polymer filled with thermally conductive ceramic powder and compounded with a silicone adhesive. It offers high thermal conductivity and insulation properties, along with flexibility, compressibility, conformability, and strong adhesion. It adapts to a wide temperature range, can fill uneven surfaces, and adheres tightly and securely to heat source devices and heat sinks, quickly dissipating heat.

[0003] At present, the Chinese utility model with publication number CN213796838U discloses an adjustable striping device for the production of thermally conductive double-sided adhesive, including a substrate and two clamping shafts arranged on the substrate. The substrate is provided with an adjusting striping device for synchronously adjusting the strip width during the production of the thermally conductive double-sided adhesive. This adjustable striping device for the production of thermally conductive double-sided adhesive, through the adjusting striping device provided on the substrate, can synchronously adjust the distance between several annular blades when producing strips of different widths of the thermally conductive double-sided adhesive, thereby realizing precise strip cutting of the thermally conductive double-sided adhesive without the need to replace different cutting knife dies, effectively saving production costs and improving the production efficiency of the thermally conductive double-sided adhesive.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it was found that although the above equipment can solve the problem of the existing thermal conductive double-sided adhesive tape needing to be cut into strips during the production process, the distance between the several blades for strip cutting is relatively fixed, and it is impossible to adjust the strip width of different thermal conductive double-sided adhesive tapes in a timely and flexible manner. As a result, not only multiple sets of cutting dies are required, which increases the production cost of the thermal conductive double-sided adhesive tape, but also the production efficiency of the thermal conductive double-sided adhesive tape is reduced when different cutting dies are replaced. However, during use, the device lacks a cleaning structure. After the blade has striped the double-sided adhesive tape for a long time, adhesives and other impurities will accumulate on the surface of the blade, resulting in a decrease in the cutting effect and a reduction in the cutting efficiency of the double-sided adhesive tape.

[0023] refer to Figure 1 and Figure 2 The moving component 8 includes a dual-axis motor 81, which is fixedly connected to the top of the base 1. The output end of the dual-axis motor 81 is fixedly connected to a gear 82. The top of the gear 82 is meshed with a tooth plate 83. The top of the tooth plate 83 is fixedly connected to the bottom of the connecting plate 5. Moving blocks 84 are fixedly installed on both sides of the tooth plate 83. Moving grooves 85 are opened on both sides of the top of the base 1. The surface of the moving block 84 is movably connected to the inner wall of the moving groove 85.

[0024] As a technical optimization solution of the present invention, by setting a moving component 8, when the scraper 7 needs to be moved to clean the blade 4, the dual-axis motor 81 is started to drive the gear 82 to rotate, and the gear 82 drives the tooth plate 83 to move. At this time, the tooth plate 83 drives the connecting plate 5 to adjust the position of the U-shaped seat 6, and then the scraper 7 can be adjusted to the bottom of the blade 4, so that the scraper 7 can scrape and clean both sides of the blade 4.

[0025] refer to Figure 1 and Figure 2 The protection component 9 includes a mounting plate 91, which is fixedly connected to both sides of the inner side of the adjustment frame 2. The inner wall of the mounting plate 91 is movably connected with a T-block 92, and the inner side of the T-block 92 is fixedly connected with a protective cover 93, which is sleeved on the surface of the blade 4.

[0026] As a technical optimization solution of the present invention, by setting up a protective component 9, when cleaning the surface of the blade 4, the user installs the protective cover 93 to the inside of the installation through the T-block 92, and covers the surrounding of the blade 4 with the protective cover 93, thereby preventing the staff from colliding with the blade 4 and causing injury, which can improve the safety of the blade 4 when cleaning.

[0027] refer to Figure 1 and Figure 2 A groove 10 is formed on the top of the protective cover 93 , and a transparent plate 11 is fixedly connected to the inner wall of the groove 10 .

[0028] As a technical optimization solution of the present invention, by providing the groove 10 and the transparent plate 11, the groove 10 can effectively fix the transparent plate 11. When cleaning the blade 4, the user can observe the surface of the blade 4 through the transparent plate 11, so that the user can understand the cleaning status of the blade 4.

[0029] refer to Figure 2 and Figure 3 The inner wall of the C-shaped seat 6 is provided with a return spring 12 , one end of the return spring 12 is fixedly connected to both sides of the inner wall of the C-shaped seat 6 , and the other end of the return spring 12 is fixedly connected to the outer side of the scraper 7 .

[0030] As a technical optimization solution of the present invention, a reset spring 12 is provided. When the scraper 7 is used to clean the blade 4, the force of the reset spring 12 can push the scraper 7 to move inward, so that the scraper 7 can be completely fitted with the surface of the blade 4, thereby being able to completely scrape off the sticky substances on the surface of the blade 4, thereby improving the flexibility and cleaning effect of the scraper 7.

[0032] As a technical optimization solution of the present invention, by setting a fixed plate 13 and a brush 14, when the surface of the blade 4 is cleaned by the scraper 7, the scraper 7 will drive the fixed plate 13 to move the brush 14 inward. When the blade 4 rotates, the surface of the blade 4 can be cleaned by the brush 14, so that the dust is separated from the surface of the scraper 7, thereby improving the cleaning effect of the surface of the blade 4.

[0034] As a technical optimization solution of the present invention, by setting the limit groove 15 and the limit rod 16, the scraper 7 can effectively move on the surface of the limit rod 16 through the limit groove 15 when moving, thereby improving the stability of the scraper 7 when moving and preventing the scraper 7 from being offset or tilted.

[0035] The working principle and use process of the present invention are as follows: when in use, the user first adjusts the blade 4 to the desired position, and adjusts and drives the rotating cylinder 3 to rotate through the adjusting frame 2, so that the rotating cylinder 3 drives the blade 4 to process the double-sided tape. When the surface of the blade 4 is long and adhesives and impurities are accumulated, the user starts the dual-axis motor 81 to drive the gear 82 to rotate, and drives the tooth plate 83 to move through the gear 82. At this time, the tooth plate 83 drives the connecting plate 5 to adjust the position of the U-shaped seat 6, and then the scraper 7 can be adjusted to the bottom of the blade 4. When the scraper 7 is adjusted to the bottom of the blade 4, the blade 4 is adjusted to the inside of the scraper 7 through the adjusting frame 2, and then the reset spring is used. The force of 12 pushes the scraper 7 to completely fit with the surface of the blade 4, and then the blade 4 is driven to rotate inside the scraper 7 by the rotating cylinder 3, so that the scraper 7 can scrape the adhesive residue on the surface of the blade 4, and then the surface of the blade 4 is cleaned by the brush 14 on the inside of the fixed plate 13, so as to facilitate the cleaning of the surface of the blade 4 and prevent the accumulation of adhesives and other impurities from affecting the cutting efficiency of the blade 4. In the process of cleaning the blade 4, the user installs the protective cover 93 to the inside of the installation through the T-block 92, and covers the periphery of the blade 4 with the protective cover 93, so as to prevent the staff from colliding with the blade 4 and causing injury, thereby improving the safety of the blade 4 when cleaning.

[0036] To sum up: this adjustable slitting device for double-sided tape production, by setting a U-shaped seat 6, a scraper 7 and a moving component 8, can effectively enable the adjusting component to move the U-shaped seat 6 to the bottom of the blade 4 through the connecting plate 5, and drive the rotating cylinder 3 through the adjusting frame 2 to make the blade 4 fit with the scraper 7. The rotation of the blade 4 can enable the scraper 7 to scrape impurities on its surface, solving the problem of the lack of a cleaning structure in the device. After the blade has been slid the double-sided tape for a long time, adhesives and other impurities will accumulate on the surface of the blade, resulting in a decrease in cutting effect and reduced double-sided tape cutting efficiency.
