Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating process technology, specifically to a coating device for producing sealing filler tape. Background Technology
[0002] In the production process of sealing filler tape, the coating process is the core link that determines the sealing performance, uniformity, and durability of the product.
[0003] In traditional coating processes, the slurry is typically pre-prepared and loaded into a hopper. However, the slurry is prone to settling or stratification within the hopper. During coating, differences in slurry flowability can cause air bubbles or thickness fluctuations on the tape surface, affecting the coating effect. Furthermore, the substrate is susceptible to lateral deviation, folding, or wrinkling during high-speed coating. Existing devices largely rely on guide rollers for passive correction, failing to actively constrain the substrate position at the coating inlet, resulting in slurry leakage or uneven thickness at the coating edges, thus impacting the coating effect. Therefore, we propose a coating device for producing sealing filler tape. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a coating device for producing sealing filler tape. It solves the problems of sedimentation or stratification of slurry in the hopper, air bubbles or thickness fluctuations on the tape surface due to differences in slurry fluidity during coating, which affect the coating effect. At the same time, the substrate is prone to lateral deviation, folding or wrinkling during high-speed coating, resulting in slurry leakage or uneven thickness at the coating edge, which also affects the coating effect.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a coating device for producing sealing filler tape, comprising a coating device body and a winding mechanism disposed on the coating device body, a support frame installed on the coating device body, a storage hopper disposed in the support frame, a loading hopper connected to the outlet of the storage hopper, and a stirring rod and a coating roller rotatably connected in the loading hopper.
[0006] A drive roller is connected to the lower part of the hopper, and the drive roller cooperates with the coating roller to apply the coating.
[0007] The hopper is equipped with a transmission mechanism, which includes a main gear and a driven gear.
[0008] The main gear is sleeved on the rotating shaft of the drive roller;
[0009] It is connected to the rotating shaft of the coating roller via a gear;

[0011] Preferably, the coating device body is equipped with a mounting frame, the mounting frame contains a bearing, and the drive roller is rotatably connected to the mounting frame via a rotating shaft that cooperates with the bearing.
[0012] Preferably, the outer peripheral walls of the two stirring rods are respectively fitted with a first pulley and a second pulley, and the outer peripheral walls of the first pulley and the second pulley are interference-fitted with a second belt. The second belt, together with the first pulley and the second pulley, is used to drive the two stirring rods to transmit synchronously.
[0013] Preferably, a third pulley is sleeved on the outer peripheral wall of the rotating shaft of the coating roller, and a first belt is interference-fitted between the outer peripheral walls of the third pulley and the first pulley. The first pulley, the third pulley and the first belt work together to drive the coating roller and the stirring rod to rotate simultaneously.
[0014] Preferably, the coating feed end of the hopper is configured as an arc surface, which cooperates with the drive roller to clamp the upper and lower ends of the filler tape substrate.
[0015] Preferably, the coating discharge end of the hopper is provided with a discharge port.
[0016] Preferably, a scraping assembly is installed at the discharge port of the hopper. The scraping assembly includes a scraping plate and a connecting seat. The connecting seat is fixed at both ends of the scraping plate and is in contact with the outer peripheral wall of the drive roller.

[0020] Its beneficial effects are as follows:
[0021] 1. The coating device for producing sealing filler tape uses an arc surface and a drive roller to adhere to the upper and lower ends of the filler tape substrate, thus limiting the substrate and effectively ensuring its stability during transport. This effectively prevents the filler tape substrate from shifting, folding, or wrinkling during high-speed coating, which could lead to leakage or uneven thickness at the coating edges and affect the coating effect. The two sides of the filler tape substrate are respectively attached to two connecting seats, which further limit the position of the filler tape substrate, effectively preventing it from tilting and improving the coating effect.
[0022] 2. The coating device for producing the sealing filler tape uses a first pulley and a second pulley to drive two stirring rods, which in turn stir the raw materials in the hopper with the stirring rods and the coating roller, effectively ensuring the uniformity of mixing and coating.

[0031] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0032] This utility model discloses a coating apparatus for producing sealing filler tape, according to the attached... Figures 1 to 3 As shown, it includes a coating device body 1 and a winding mechanism 5 installed on the coating device body 1. A support frame 2 is installed on the coating device body 1. A storage hopper 21 is provided in the support frame 2. The outlet of the storage hopper 21 is connected to a loading hopper 3. A stirring rod 31 and a coating roller 32 are rotatably connected in the loading hopper 3.
[0033] A drive roller 6 is connected to the lower part of the hopper 3, and the drive roller 6 cooperates with the coating roller 32 to apply coating.
[0034] The hopper 3 is equipped with a transmission mechanism 7, which includes a main gear 71 and a driven gear 72.
[0035] The main gear 71 is sleeved on the rotating shaft of the drive roller 6;
[0036] The gear 72 is fitted onto the rotating shaft of the coating roller 32;
[0037] The main gear 71 and the driven gear 72 mesh to drive the drive roller 6 and the coating roller 32 to rotate synchronously.
[0038] A mounting frame 61 is installed on the main body 1 of the coating device. A bearing is installed inside the mounting frame 61. The drive roller 6 is rotatably connected to the mounting frame 61 through a rotating shaft and the bearing.
[0039] A hot air drying box 4 is installed on the main body 1 of the coating device. After the filler tape substrate is coated, the slurry is dried and shaped by the hot air drying box 4.
[0040] The filler tape substrate is unwound via an unwinding mechanism, which consists of a substrate roll, a tension detection and control device, a servo motor, a web guiding device, and a joint detection and processing device.
[0041] The winding mechanism 5 consists of a winding shaft, a tension detection and control device, a web guiding device, and a pressure roller. The winding mechanism 5 is driven by a transmission and control mechanism, which consists of a main drive motor, independent drive motors for each unit, a frequency converter / servo driver, a PLC / DCS control system, a human-machine interface, and a sensor network.
[0042] According to the appendix Figure 3 As shown, the outer peripheral walls of the two stirring rods 31 are respectively fitted with a first pulley 73 and a second pulley 74. The outer peripheral walls of the first pulley 73 and the second pulley 74 are interference-fitted with a second belt 77. The second belt 77, together with the first pulley 73 and the second pulley 74, is used to drive the two stirring rods 31 to drive synchronously.
[0043] The first pulley 73 and the second pulley 74 work together to drive the two stirring rods 31, so that the stirring rods 31 and the coating roller 32 stir the raw materials in the hopper 3, effectively ensuring the uniformity of mixing and coating.
[0044] A third pulley 75 is sleeved on the outer peripheral wall of the rotating shaft of the coating roller 32. The outer peripheral walls of the third pulley 75 and the first pulley 73 are interference-fitted with a first belt 76. The first pulley 73, the third pulley 75 and the first belt 76 work together to drive the coating roller 32 and the stirring rod 31 to rotate simultaneously.
[0045] With the cooperation of the third pulley 75 and the first pulley 73, when the coating roller 32 and the drive roller 6 rotate to drive the filler tape substrate to be transported and coated, the stirring rod 31 rotates to ensure that the raw materials in the hopper 3 are mixed evenly and stirred during coating, effectively avoiding the waste of kinetic energy.
[0046] According to the appendix Figure 4 As shown, the coating feed end of the hopper 3 is set as an arc surface, which cooperates with the drive roller 6 to clamp the upper and lower ends of the filler tape substrate.
[0047] By bonding the curved surface and drive roller 6 to the upper and lower ends of the filler tape substrate, the filler tape substrate is confined, effectively ensuring the stability of the filler tape substrate during the transmission process. This effectively avoids problems such as lateral deviation, folding, or wrinkling of the filler tape substrate during high-speed coating, which could cause leakage of slurry at the coating edge or uneven thickness, affecting the coating effect.
[0048] The hopper 3 has a discharge port at one end for coating.
[0049] By opening a discharge port, the coated material is prevented from being scraped off, thus avoiding ineffective coating.
[0050] According to the appendix Figure 4 and Figure 5 As shown, a scraping assembly 8 is installed at the discharge port of the hopper 3. The scraping assembly 8 includes a scraping plate 81 and a connecting seat 82. The connecting seat 82 is fixed at both ends of the scraping plate 81 and is in contact with the outer peripheral wall of the drive roller 6.
[0051] After the filler tape substrate is coated by the coating roller 32 and the drive roller 6, it is conveyed outward through the scraper plate 81 in the downward direction.
[0052] The length of the scraper 81 is adapted to the width of the filler tape substrate, and the connecting seat 82 is adjusted accordingly to the scraper 81.
[0053] After the filler tape substrate passes through the coating roller 32 and the drive roller 6, the filler tape substrate is located below the scraper plate 81, and both sides of the filler tape substrate are respectively attached to the two connecting seats 82. The connecting seats 82 further limit the position of the filler tape substrate, effectively preventing the filler tape substrate from tilting and improving its coating effect.
[0054] The height of the scraper 81 is adapted to the thickness of the filler tape substrate.
[0055] Excess slurry on the filler tape substrate is scraped off by scraper 81, effectively ensuring the thickness of the filler tape substrate coating.
[0056] The connecting seat 82 is fixedly connected to the mounting seat 83, which is detachably mounted on the outer peripheral wall of the hopper 3.
[0057] By disassembling the mounting base 83, the scraper 81 and the connecting base 82 can be disassembled. Different scraping components 8 can be selected according to the filler tape substrate being processed, and processed in conjunction with the filler tape substrate.
