Description

Technical Field

[0001] The utility model belongs to the technical field of conductive foam production, in particular to a glue scraping device for a pressing roller of a conductive foam production system. Background Art

[0002] Conductive foam refers to a flame-retardant sponge wrapped with conductive cloth. After a series of treatments, it has good surface conductivity and can be easily fixed to the device to be shielded with adhesive tape. There are shielding materials with different cross-sectional shapes, installation methods, UL grades and shielding effectiveness to choose from. During the production process of conductive foam, a pressure roller is required to work.

[0003] However, there are some problems with the existing technology: At present, in the production process of conductive foam, the nip roller is often contaminated with glue. If the glue is not cleaned in time, it will affect the normal operation of the nip roller and lead to a decline in product quality. For example, problems such as uneven glue layer and inconsistent thickness will occur. The traditional cleaning method is inefficient and cannot completely remove the glue. The residual glue may cause adverse effects in subsequent production. Moreover, as the production continues, the accumulation of glue will increase, and the threat to production efficiency and product quality will gradually increase. Therefore, we propose a glue scraping device for the nip roller of a conductive foam production system. Utility Model Content

[0024] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0025] like Figures 1 to 5 As shown, an embodiment of the utility model provides a scraper device for a press roller of a conductive foam production system, comprising an upper clamping ring 1, a lower clamping ring 2 and a limit assembly 9, wherein the upper clamping ring 1 is located at the top of the lower clamping ring 2, two groups of fixed blocks 3 are fixedly installed on the right side of the upper clamping ring 1, and a rotating block 4 is fixedly installed on the right side of the lower clamping ring 2. The rotating block 4 is rotatably installed through an axle pin and the fixed block 3, and scrapers 5 are arranged inside the upper clamping ring 1 and the lower clamping ring 2.

[0026] The scraper 5 is made of rubber. When the bottom of the scraper 5 contacts the surface of the press roller, since the surface of the press roller is mostly made of plush, the rubber scraper 5 will also prevent the plush on the press roller from being scraped off. When the scraper 5 is severely worn due to long-term use, the upper clamping ring 1 and the lower clamping ring 2 can be separated to separate them from the press roller. Finally, the severely worn scraper 5 can be replaced to prevent the scraper 5 from being severely worn, resulting in uneven scraping of the glue on the press roller.

[0027] A rectangular block 7 is fixedly installed on the left side of the upper clamping ring 1 , and a mounting block 8 is fixedly installed on the left side of the lower clamping ring 2 .

[0028] The limiting assembly 9 is fixedly installed at the bottom of the rectangular block 7, and one side of the limiting assembly 9 is fixedly installed with the mounting block 8. The limiting assembly 9 is used to limit the rectangular block 7 and the mounting block 8 to prevent the upper clamping ring 1 and the lower clamping ring 2 from separating.

[0029] Place the upper clamping ring 1 and the lower clamping ring 2 on the surface of the press roller. At this time, the upper clamping ring 1 and the lower clamping ring 2 can be rotated inward at the same time to make the scraper 5 contact the surface of the press roller. At this time, the rectangular block 7 and the mounting block 8 can be limited by the limiting assembly 9. At this time, the upper clamping ring 1 and the second clamping ring can be pulled at the same time. The movement of the upper clamping ring 1 and the lower clamping ring 2 drives the scraper 5 to move, so that the glue on the surface of the press roller can be scraped off.

[0030] The limiting assembly 9 includes a slide rod 91, a slide block 92 is slidably installed on the surface of the slide rod 91, a slot 93 is provided at the bottom of the mounting block 8, an L-shaped plate 94 is fixedly installed at the bottom of the mounting block 8, an insertion rod 95 is slidably installed on the top of the inner wall of the L-shaped plate 94, a triangular plate 96 is fixedly installed on the top of the insertion rod 95, and the top of the triangular plate 96 is in contact with the bottom of the slide block 92.

[0031] Through the mutual cooperation of the slide bar 91, the slider 92, the slot 93, the L-shaped plate 94, the plug rod 95 and the triangular plate 96, the upper clamping ring 1 can be rotated toward the bottom, which will drive the rectangular block 7 to rotate toward the bottom. When the bottom of the rectangular block 7 contacts the top of the mounting block 8, the slide bar 91 and the slider 92 will rotate to the bottom of the mounting block 8. When the bottom of the slide bar 91 contacts the top of the triangular plate 96, the triangular plate 96 will drive the plug rod 95 to move toward the bottom. When the slide bar 91 is rotated to a vertical state, the plug rod 95 can be pushed toward the top. The movement of the plug rod 95 toward the top drives the triangular plate 96 toward the top. The movement of the triangular plate 96 toward the top will push the slide bar 92 into the slot 93, thereby limiting the rectangular block 7 and the mounting block 8.

[0032] A spring 97 is sleeved on the surface of the insertion rod 95 , the bottom of the spring 97 is fixedly mounted to the bottom of the inner wall of the L-shaped plate 94 , and the top of the spring 97 is fixedly mounted to the bottom of the triangular plate 96 .

[0033] By setting the spring 97, the triangular plate 96 and the insert rod 95 can always bear the elastic force of the spring 97, so that the slider 92 can be more stable when entering the slot 93, preventing the slider 92 and the slot 93 from being separated, thereby making it impossible to limit the rectangular block 7 and the mounting block 8, and thus making it impossible to limit the upper snap ring 1 and the lower snap ring 2.

[0034] The bottom of the plug rod 95 penetrates to the bottom of the L-shaped plate 94 , and the bottom of the plug rod 95 and the L-shaped plate 94 are slidably installed. A stopper 10 is fixedly installed on the bottom of the plug rod 95 , and the top of the stopper 10 contacts the bottom of the L-shaped plate 94 .

[0035] By setting the stopper 10, the insertion rod 95 can be limited to prevent the insertion rod 95 from being subjected to excessive elastic force of the spring 97, which would cause the insertion rod 95 to separate from the L-shaped plate 94, thereby making the insertion rod 95 unable to reset.

[0036] A limit block 11 is fixedly installed at the bottom of the slide bar 91 , the top of the limit block 11 contacts the bottom of the slide block 92 , and the limit block 11 and the triangular plate 96 are slidably installed.

[0037] By setting the limit block 11, the slider 92 can be limited to prevent the slider 92 from being separated from the slide rod 91 due to its own gravity, resulting in the slider 92 being unable to enter the slot 93, thereby failing to limit the rectangular block 7 and the mounting block 8.

[0038] A plurality of groups of bolts 12 are disposed on the outer sides of the upper clamping ring 1 and the lower clamping ring 2. The inner ends of the bolts 12 penetrate into the interior of the scraper 5. The bolts 12 and the scraper 5 are threadedly mounted.

[0039] The bolts 12 are provided to disassemble the scraper 5 so that the scraper 5 can be easily replaced when worn out after long-term use, thereby preventing the scraper 5 from being severely worn and causing uneven scraping of the glue on the nip roller.

[0040] A connection frame 13 is fixedly mounted on the top of the upper clamping ring 1 and the bottom of the lower clamping ring 2. A threaded groove 6 is provided inside the connection frame 13. The screw is used to rotate inside the threaded groove 6 so that the upper clamping ring 1 and the lower clamping ring 2 can move and scrape the glue.

[0041] Through the mutual cooperation between the connecting frame 13 and the threaded groove 6, the two sides of the connecting frame 13 are arc-shaped. When encountering a nip roller with a smaller stroke, the connecting frame 13 can be pushed manually. The movement of the connecting frame 13 drives the upper clamping ring 1, the lower clamping ring 2 and the scraper 5 to move, so that the glue on the nip roller can be scraped off. When encountering a nip roller with a larger stroke, the screw can be inserted into the threaded groove 6, and then it can be driven by the motor to move, so that the glue on the surface of the nip roller can also be scraped off.

[0042] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
