Description

Technical Field

[0001] This utility model relates to the field of foam tape processing technology, specifically a high-precision coating and bonding processing equipment for foam tape. Background Technology

[0002] Foam tape is made by coating one or both sides of EVA or PE foam with solvent-based (or hot-melt) pressure-sensitive adhesive and then covering it with release paper. It provides sealing and shock absorption. It exhibits excellent sealing performance, resistance to compression deformation, flame retardancy, and wettability. The product is widely used in electronic and electrical products, mechanical parts, various small household appliances, mobile phone accessories, industrial instruments, computer and peripheral equipment, automotive parts, audio-visual equipment, toys, cosmetics, etc. During foam production, it is often necessary to attach tape to one end of the foam, which requires lamination equipment.

[0003] In existing technologies, when foam is attached to the bonding surface, the foam is mainly pressed together by the operator's hands. This method has serious shortcomings. On the one hand, the operator cannot press all parts of the foam, resulting in some parts of the foam not being pressed together, making the foam easy to fall off later. On the other hand, the work efficiency is low, and the pressure applied manually cannot be well controlled, resulting in uneven pressure on the foam surface and making the foam surface uneven. Therefore, corresponding improvements are needed to address these problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-precision coating and bonding processing equipment for foam tape, comprising a base plate, a mounting hole being provided on one side of the top of the base plate, and a processing table being mounted on the other side of the top of the base plate. The processing table has a mounting groove inside, and both inner walls of the mounting groove are connected to one end of a rolling shaft via bearings. A side plate is mounted on one end of the top of the base plate near the processing table, and two sets of motors are mounted on the outer side of the side plate. The output ends of both sets of motors are connected to placement rollers, and the outer surfaces of the placement rollers are connected via shafts. The mounting plate has a limiting plate. The outer surfaces of the two sets of placement rollers are respectively movably wound with foam rolls and adhesive tape rolls. A second side plate is movably installed at the other end of the top of the base plate near the processing table. Two sets of bearing sleeves are installed on the inner side of the second side plate. An installation plate is installed on the outer side of the second side plate near the bottom end. An installation bolt is movably screwed into the interior of the installation plate. An installation frame is installed on the inner side of the base plate. An electric push rod is installed on the inner wall of the top of the installation frame. A connecting plate is installed at the bottom end of the electric push rod through the mounting plate. A clamping rod is installed at both ends of the connecting plate. A clamping roller is rotatably connected to the bottom end of each clamping rod.

[0006] Preferably, the outer diameter of the mounting bolt is adapted to the inner diameter of the mounting hole, and the bottom end of the mounting bolt extends into the interior of the mounting hole and is movably screwed into it.

[0007] Preferably, the number of the rolling shafts is several groups, and the several groups of rolling shafts are distributed in a straight array inside the mounting groove.

[0008] Preferably, the outer diameter of the placement roller is adapted to the inner diameter of the bearing sleeve, and one end of the placement roller extends into the interior of the bearing sleeve and is movably inserted into it.

[0009] Preferably, four sets of limiting posts are installed on one side of the bearing sleeve, and the four sets of limiting posts are arranged in a centrally symmetrical manner with the center point of the bearing sleeve as the center point.

[0010] Preferably, the mounting bracket is L-shaped, and the mounting plate, connecting plate, and clamping rod are positioned directly above the foam roll.

[0011] Preferably, the outer surface of the adhesive tape roll is fitted to the outer surface of several sets of rolling shafts.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By incorporating components such as a processing table, mounting groove, rolling shaft, mounting bracket, electric push rod, mounting plate, connecting plate, clamping rod, and clamping roller, this design effectively solves the problem of operators not being able to press all parts of the foam during existing foam tape processing. This results in some parts of the foam not being pressed, making it prone to falling off later. Furthermore, manual work efficiency is low, and the pressure applied manually cannot be well controlled, leading to uneven pressure on the foam surface and an uneven surface.

[0019] To achieve the above objectives, according to Figures 1-3As shown, this utility model provides the following technical solution: a high-precision coating and bonding processing equipment for foam tape, including a base plate 1, a mounting hole 11 is provided on one side of the top of the base plate 1, and a processing table 12 is installed on the other side of the top of the base plate 1. A mounting groove 13 is provided inside the processing table 12, and both inner walls of the mounting groove 13 are connected to one end of a rolling shaft 14 via bearings. The rolling shafts 14 are arranged in several groups in a straight array inside the mounting groove 13. A side plate is installed on one end of the top of the base plate 1 near the processing table 12. 15, and two sets of motors 16 are installed on the outer side of the side plate 15. The output ends of the two sets of motors 16 are connected to the placement rollers 17. The outer surface of the placement rollers 17 is fitted with a limit plate 171 through the bearing. The outer diameter of the placement rollers 17 is adapted to the inner diameter of the bearing sleeve 21. One end of the placement rollers 17 extends into the interior of the bearing sleeve 21 and is movably inserted into it. The outer surfaces of the two sets of placement rollers 17 are respectively movably wound with foam rolls 18 and adhesive rolls 19. The foam rolls 18 and adhesive rolls 19 are stacked one on top of the other. The outer surface of the adhesive rolls 19 is in contact with the outer surface of several sets of rolling shafts 14.

[0020] A second side plate 2 is movably installed at the top of the base plate 1 on the other end of the side plate 1, near the processing table 12. Two sets of bearing sleeves 21 are installed on the inner side of the second side plate 2. Four sets of limiting posts 22 are installed on one side of the bearing sleeves 21, and the four sets of limiting posts 22 are centrally symmetrical about the center point of the bearing sleeves 21. A mounting plate 23 is installed on the outer side of the second side plate 2 near the bottom. A mounting bolt 24 is movably screwed into the inside of the mounting plate 23. The outer diameter of the mounting bolt 24 is adapted to the inner diameter of the mounting hole 11, and the bottom end of the mounting bolt 24 extends into the inside of the mounting hole 11 and is movably screwed into it.

[0021] An mounting bracket 3 is installed on the inner side of the base plate 1, and an electric push rod 31 is installed on the inner wall of the top of the mounting bracket 3. A connecting plate 33 is installed at the bottom of the electric push rod 31 through the mounting plate 32, and a clamping rod 34 is installed at both ends of the connecting plate 33. The mounting bracket 3 is L-shaped, and the mounting plate 32, the connecting plate 33 and the clamping rod 34 are positioned directly above the foam roll 18. A clamping roller 35 is rotatably connected to the bottom of the clamping rod 34.

[0022] In use, the user can sequentially place the foam roll 18 and adhesive tape roll 19 onto the outer surface of the corresponding placement roller 17, in an up-down arrangement. At this time, one end face of the foam roll 18 and adhesive tape roll 19 will be in contact with one side surface of the corresponding limiting plate 171. After that, the side plate 2 can be placed on the top side of the base plate 1, so that the ends of the two sets of placement rollers 17 can be sequentially inserted into the interior of the corresponding bearing sleeve 21. At the same time, the end faces of the four sets of limiting posts 22 will be in contact with the other end faces of the foam roll 18 and adhesive tape roll 19 respectively. The foam roll 18 and adhesive tape roll 19 are positioned to limit their movement to the left and right, preventing them from shifting during rotation. Afterward, the user can rotate the mounting bolt 24, allowing its bottom end to extend into the mounting hole 11 and be movably screwed in, thus completing the installation between the base plate 1 and the side plate 2. At this point, one end of the foam roll 18 and adhesive tape roll 19 can be stacked flat on the outer surface of several sets of rolling shafts 14. Then, the electric... The electric push rod 31 is activated, causing the mounting plate 32 to move downwards. This causes the connecting plate 33 and the two sets of clamping rods 34 to move downwards as well, ultimately bringing the outer surfaces of the two sets of clamping rollers 35 into contact with the top surface of the foam roll 18. Afterwards, the user can activate the two sets of motors 16, causing the two sets of placement rollers 17 to rotate, which in turn causes the foam roll 18 and the adhesive tape roll 19 to rotate. This allows the foam roll 18 and adhesive tape roll 19 located on the outer surface of several sets of rolling shafts 14 to move to one side, thereby enabling the several sets of rolling shafts 14 to roll accordingly. The two sets of pressing rollers 35 will also roll accordingly. Under the pressing and rolling action of the two sets of pressing rollers 35, the foam roll 18 and adhesive tape roll 19 can be bonded together vertically. Since there is one set of pressing rollers 35 at the front and one at the back, two vertical bonding operations can be performed, thereby ensuring the bonding quality of the foam roll 18 and adhesive tape roll 19.
