Description

Technical Field

[0001] This utility model relates to the field of adhesive coating equipment technology, and in particular to a strip adhesive coating equipment. Background Technology

[0002] In existing strip coating processes, while coating machines can achieve high-quality coating results and have high production capacity, their initial investment and maintenance costs remain high, making it difficult to gain a significant advantage in market price competition. Twin-roller coating machines, as a low-cost, high-efficiency coating equipment, are widely used in coating operations for sheets, plastic parts, and other fields. However, they have strict limitations on the thickness of the substrate, making them unsuitable for thin-walled products with a thickness of less than 2mm, easily leading to glue leakage and resulting in quality problems such as uneven coating thickness or localized glue shortages. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a strip coating equipment that, by improving upon existing two-roller coating machines, is suitable for coating thin-walled products with a thickness of less than 2mm. The coating is uniform, effectively improving the coating efficiency and quality of the strip while reducing initial equipment investment costs.

[0004] The strip coating equipment according to an embodiment of the present invention includes: Base frame; A glue-applying roller assembly includes a glue roller and a smooth roller, both of which are rotatably mounted on the base frame about their own axes. The glue roller is connected to a first transmission structure that drives its rotation. A glue tank assembly is disposed above the glue application roller assembly and is used to supply glue to the glue application roller assembly; A traction roller is rotatably mounted on the base frame about its own axis and is connected to a second transmission structure that drives its rotation. Along the conveying direction of the strip, the traction roller is positioned behind the glue-applying roller group; in the vertical direction, the traction roller is higher than the glue-applying roller group.

[0005] The strip coating equipment according to the embodiments of the present utility model has at least the following beneficial effects: By installing a traction roller behind the coating roller assembly, the traction roller can rotate around its own axis, and the rotation speed of the traction roller is the same as that of the coating roller. This provides the moving power to tension the strip and prevents glue accumulation on the strip. The height of the traction roller is greater than the height of the coating roller assembly, which allows the strip to adhere tightly to the coating roller assembly, thus enabling the coating of thin-walled products with a thickness of less than 2mm. The coating of thin-walled products with a thickness of less than 2mm can be achieved by adding a traction roller to an existing two-roller coating machine. The modification cost is low, which can effectively reduce the initial equipment investment cost.

[0006] According to some embodiments of the present invention, the base frame is provided with a strip groove, the optical roller is installed in the strip groove and connected to a first adjustment component, the first adjustment component drives the optical roller to slide along the strip groove to adjust the distance between the optical roller and the rubber roller.

[0007] According to some embodiments of the present invention, the first adjusting component includes an adjusting rod and a first adjusting wheel. The adjusting rod is rotatably mounted on the optical roller about its own axis, and the first adjusting wheel is throttle-connected to the adjusting rod. The first adjusting wheel rotates, causing the adjusting rod to slide horizontally, which in turn causes the light roller to slide along the strip groove.

[0008] According to some embodiments of the present invention, the end of the optical roller is fitted with a connector, the base frame is provided with a first support structure, the first end of the adjusting rod in the length direction is rotatably mounted on the connector about its own axis, and the second end passes through the first support structure.

[0011] According to some embodiments of the present invention, an extension rod is provided on each of the two opposite sides of the groove plates, and a central shaft is passed through the extension rod, and the central shaft is connected to the extension rod in a driving manner. The central shaft is rotatably mounted on the base frame around its own axis. The rotation of the central shaft can drive the two slot plates to move relative to each other to adjust the size of the opening.

[0012] According to some embodiments of the present invention, the base frame is provided with a second support structure, and the central shaft is rotatably inserted through the second support structure about its own axis; A second adjusting wheel is installed at the end of the central shaft, and a rack is installed on the base frame.

[0022] Reference Figures 1 to 4 This application discloses a strip coating equipment, including a base frame 100, a coating roller group 200, a glue tank assembly 300, and a traction roller 400. The coating roller group 200, the glue tank assembly 300, and the traction roller 400 are all installed on the base frame 100. Along the conveying direction of the strip, the traction roller 400 is located behind the coating roller group 200, and the glue tank assembly 300 is located above the coating roller group 200. The glue tank assembly 300 is used to provide glue to the coating roller group 200, the coating roller group 200 is used to coat the strip with glue, and the traction roller 400 is used to improve the applicability of the coating roller group 200 and the uniformity of the glue coating on the strip.

[0023] Reference Figure 1 As shown, the coating roller assembly 200 includes a coating roller 210 and a smooth roller 220. Both the coating roller 210 and the smooth roller 220 are rotatably mounted on the base frame 100 around their own axes. The coating roller 210 is connected to a first transmission structure 211 that drives its rotation, and the traction roller 400 is connected to a second transmission structure 410 that drives its rotation. The rotational speed of the coating roller 210 is the same as that of the traction roller 400, and in the vertical direction, the traction roller 400 is higher than the coating roller assembly 200. By installing a traction roller 400 behind the coating roller assembly 200, the traction roller 400 can rotate around its own axis, and the rotation speed of the traction roller 400 is the same as that of the glue roller 210. This provides the moving power to the strip to tension the strip and prevent glue accumulation on the strip. The height of the traction roller 400 is greater than the height of the coating roller assembly 200, which allows the strip to adhere tightly to the coating roller assembly 200, thereby enabling the coating of thin-walled products with a thickness of less than 2mm. The coating of thin-walled products with a thickness of less than 2mm can be achieved by adding the traction roller 400 to the existing double-roller glue coater. The modification cost is low, which can effectively reduce the initial equipment investment cost.

[0024] It is conceivable that, in order to ensure that the rotational speed of the glue roller 210 is equal to that of the traction roller 400, and to effectively reduce the manufacturing cost of the glue coating equipment, reference should be made to... Figure 1As shown, the adhesive coating equipment in this embodiment is equipped with only one drive device 160, which is installed below the adhesive coating roller group 200. The output end of the drive device 160 is simultaneously connected to the first transmission structure 211 and the second transmission structure 410, thereby ensuring that the rotational speeds of the adhesive roller 210 and the traction roller 400 are equal. The drive device 160 is preferably an electric motor, and the first transmission structure 211 and the second transmission structure 410 can be structures such as belts and chains.

[0025] In the embodiments of this application, the distance between the glue roller 210 and the smooth roller 220 of the glue application roller assembly 200 is adjustable, thereby adapting to different types and viscosities of adhesives. Since the glue roller 210 is connected to the first transmission structure 211, adjusting the position of the glue roller 210 requires simultaneous adjustment of the first transmission structure 211, resulting in high adjustment costs and difficulty. Therefore, it is preferable to adjust the position of the smooth roller 220 to achieve adjustment of the distance between the glue roller 210 and the smooth roller 220. (Refer to...) Figure 1 , Figure 2 As shown, the base frame 100 has a strip-shaped hole. The optical roller 220 is installed in the strip-shaped hole and connected to a first adjusting component 230. The first adjusting component 230 drives the optical roller 220 to slide along the strip-shaped hole to adjust the distance between the optical roller 220 and the rubber roller 210. The strip-shaped hole is horizontally set, and the first adjusting component 230 is used to drive the optical roller 220 to slide horizontally along the strip-shaped hole, thereby realizing the adjustment of the distance between the rubber roller 210 and the optical roller 220.

[0026] Reference Figure 2 As shown, the first adjustment assembly 230 includes an adjustment rod 231 and a first adjustment wheel 232. The adjustment rod 231 is rotatably mounted on the optical roller 220 around its own axis, and the first adjustment wheel 232 is throttle-connected to the adjustment rod 231. Rotation of the first adjustment wheel 232 causes the adjustment rod 231 to slide horizontally, thereby causing the optical roller 220 to slide along the strip-shaped hole. Specifically, a connector 221 is sleeved at the end of the optical roller 220, and the connector 221 can be connected to the optical roller 220 via a key or other means. The base frame 100 is provided with a first support structure 110. The first end of the adjustment rod 231 in the length direction is rotatably mounted on the connector 221 around its own axis, and the second end passes through the first support structure 110. The first adjustment wheel 232 is throttle-connected to the middle part of the adjustment rod 231. The first adjustment wheel 232 is rotatably mounted on the base frame 100 around its own axis. The first adjustment wheel 232 can be manually rotated by a handwheel or driven by a motor; this is not limited in this embodiment.

[0027] To precisely control and manage the distance between the rubber roller 210 and the smooth roller 220, refer to... Figure 2As shown, the base frame 100 of this embodiment is equipped with a scale 120, which is correspondingly set with the adjusting rod 231. Preferably, the scale 120 is set at the end of the adjusting rod 231. The scale 120 is equipped with a graduation. When the first adjusting wheel 232 rotates, it will drive the adjusting rod 231 to move horizontally, thereby causing the adjusting rod 231 and the scale 120 to move relative to each other. By observing that the end of the adjusting rod 231 is located at the graduation position of the scale 120, the distance between the rubber roller 210 and the light roller 220 can be calculated.

[0028] In the embodiments of this application, reference is made to Figure 3 , Figure 4 As shown, the glue tank assembly 300 is disposed above the glue application roller assembly 200. The glue tank assembly 300 includes two opposing groove plates 310, with a V-shaped groove formed between the two groove plates 310 for receiving glue. The bottom of the V-shaped groove has an opening, and the glue in the V-shaped groove flows to the glue application roller assembly 200 through the bottom opening. Different strip materials use different glues, and different glues also have different viscosities and flowability. In order to be suitable for different types of glues, the bottom opening of the V-shaped groove is preferably set to be adjustable.

[0029] To adjust the size of the opening at the bottom of the V-groove, each of the two groove plates 310 in this embodiment is provided with an extension rod 320 on its opposite side. A central shaft 330 passes through the extension rod 320, and the central shaft 330 is kinetically connected to the extension rod 320. The central shaft 330 is rotatably mounted on the base frame 100 around its own axis. Rotation of the central shaft 330 can drive the two groove plates 310 to move relative to each other to adjust the opening size. (Refer to...) Figure 3 , Figure 4 As shown, extension rods 320 are provided at both ends of the groove plate 310 along its length. The central shaft 330 passes through the extension rods 320. The central shaft 330 and the extension rods 320 are connected by means of welding or other fixed connections, or by key connections, or by fasteners such as bolts. In this embodiment, no limitation is made.

[0030] Reference Figure 3 , Figure 4 As shown, the base frame 100 is provided with a second support structure 130, and a central shaft 330 is rotatably mounted through the second support structure 130 around its own axis. A second adjusting wheel 331 is installed at the end of the central shaft 330, and a rack 140 is installed on the base frame 100. The rack 140 meshes with the second adjusting wheel 331, and the rack 140 can move and be fixed relative to the second adjusting wheel 331. Moving the rack 140 can drive the second adjusting wheel 331 to rotate, thereby driving the central shaft 330 to rotate synchronously. Specifically, the base frame 100 is also provided with a third support structure 170, and the rack 140 is slidably mounted on the third support structure 170. The rack 140 can be vertically or horizontally arranged, which is not limited in this embodiment.

[0031] Reference Figure 4 As shown. In the embodiments of this application, the second adjusting wheel 331 can be a ratchet, and the rack 140 can be a ratchet tooth, so as to... Figure 4 For example, the ratchet and ratchet teeth work together to limit the ratchet's counterclockwise rotation, thus ensuring the stability of the opening size at the bottom of the V-groove. The rack 140 is vertically arranged and connected to an elastic element 141 that drives it downward. When it is necessary to reduce the opening size at the bottom of the V-groove, the second adjusting wheel 331 is rotated clockwise, and then the ratchet and ratchet teeth can automatically lock together. The third support structure 170 is slidably mounted on the base frame 100. When it is necessary to increase the opening size at the bottom of the V-groove, the third support structure 170 is first slid horizontally to move the rack 140 away from the second adjusting wheel 331. Then, the groove plate 310 will rotate around the central axis 330 under its own weight. When it rotates to a set angle, the third support structure 170 is slid to make the rack 140 mesh with the second adjusting wheel 331, thereby locking the groove plate 310.

[0032] It is conceivable that the second adjusting wheel 331 could also be configured as a conventional spur gear, with the rack 140 arranged vertically or horizontally, and connected to a screw or similar structure to drive its lifting or horizontal sliding, and the screw fitted with a nut to lock its position. Figure 4 For example, when the rack 140 rises, it drives the second adjusting wheel 331 to rotate counterclockwise, thereby increasing the opening size at the bottom of the V-groove. After the opening size at the bottom of the V-groove is adjusted to the set size, the nut is locked. When the rack 140 falls, it drives the second adjusting wheel 331 to rotate clockwise, thereby decreasing the opening size at the bottom of the V-groove. After the opening size at the bottom of the V-groove is adjusted to the set size, the nut is locked.

[0033] In the embodiments of this application, in order to prevent glue from falling and accumulating on the ground, the base frame 100 is also equipped with a glue collection tank 150. The glue collection tank 150 is located below the glue application roller group 200 to collect the dripping glue. A discharge pipe 151 is provided in the middle of the glue collection tank 150, and a locking valve 152 is provided on the discharge pipe 151 to control the opening and closing of the discharge pipe 151.
