[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0030] Example: Figure 1-4 As shown, this utility model provides a technical solution: a tightly fitting shock-absorbing and energy-absorbing foam bonding device, including a support 1.

The traction bonding mechanism 3 includes a groove 301, a movable plate 302, a limiting rod 303, a support spring 304, a clamping roller 305, a rotary motor 306, a vertical frame 307, a fixing rod 308, a slider 309, a tension spring 310, and a guide roller 311.

[0031] Both vertical plates 2 have grooves 301 at their top interiors. Movable plates 302 are movably connected inside both grooves 301. Limiting rods 303 are symmetrically engaged at the top of the movable plates 302. Supporting springs 304 are engaged between the movable plates 302 and the grooves 301 at positions corresponding to the outer sides of the limiting rods 303. Clamping rollers 305 are rotatably connected between the two movable plates 302 and between the two vertical plates 2. A rotary motor 306 is bolted to one end of one vertical plate 2 at a position corresponding to the rotating shaft of the clamping roller 305.

[0032] A vertical frame 307 is symmetrically connected to the top of the bracket 1 at one side of the vertical plate 2 via bolts. The top and bottom of the two vertical frames 307 are both secured with fixing rods 308. A slider 309 is movably sleeved on the outside of the fixing rod 308. A tension spring 310 is secured between the slider 309 and the vertical frame 307 at the outer side of the fixing rod 308. A guide roller 311 is rotatably connected between the two opposing sliders 309. To facilitate the bonding of foam and double-sided tape together, both ends of the movable plate 302 are slidably connected to the inner wall of the groove 301. The rotary motor 306 is powered by an external power source. Both ends of the slider 309 are slidably connected to the inner wall of the vertical frame 307.

[0033] The top two sides of the bracket 1 are provided with a placement and winding mechanism 4. The placement and winding mechanism 4 includes a fixed plate 401, a placement groove 402, a crossbar 403, a retaining ring 404, an anti-deviation ring 405, a support plate 406, a winding rod 407, a transmission rod 408, a sprocket 409, a chain 410 and a support plate 411.

[0034] A fixing plate 401 is symmetrically connected to one side of the top of the bracket 1 by bolts. Each of the two fixing plates 401 has a placement groove 402 at equal intervals at one end. A crossbar 403 is placed inside the placement groove 402. Both ends of the crossbar 403 are threaded with retaining rings 404. An anti-deviation ring 405 is threaded on the side of the crossbar 403 corresponding to the retaining ring 404.

[0035] A support plate 406 is snapped onto one side of the top of the bracket 1. A winding rod 407 is rotatably connected inside the support plate 406. A transmission rod 408 is rotatably connected to one end of the vertical plate 2, corresponding to the side of the rotating shaft of the clamping roller 305. Sprockets 409 are fixedly sleeved on the outside of the transmission rod 408 and the outside of the winding rod 407. Chains 410 are sleeved on the outside of both sprockets 409. A support plate 411 is bolted to the top of the bracket 1, corresponding to the bottom of the winding rod 407. To facilitate the winding of the laminated foam, one end of the anti-deviation ring 405 is attached to the inner wall of the fixed plate 401, one end of the transmission rod 408 is connected to one end of the rotating shaft of the clamping roller 305, and the top of the support plate 411 is attached to the outside of the winding rod 407.

[0036] Positioning blocks 5 are snapped into the middle of the inner walls of the two vertical frames 307. A winding rod 6 is rotatably connected between the two positioning blocks 5. A transmission wheel 7 is fixedly sleeved on the outer side of the winding rod 6 and the outer side of the transmission rod 408. A belt 8 is sleeved on the outer side of the two transmission wheels 7. In order to facilitate the collection of the anti-stick paper on the double-sided tape, one end of the winding rod 6 passes through one end of the positioning block 5. The outer diameter of the transmission wheel 7 on the vertical plate 2 is larger than the outer diameter of the transmission wheel 7 on the vertical frame 307.

[0037] The working principle and usage process of this utility model are as follows: First, rotate the retaining ring 404 and the anti-deviation ring 405 to move the horizontal bar 403 out, so that the foam roll and the double-sided adhesive roll can be respectively fitted onto the horizontal bar 403. Then, the horizontal bar 403 is placed inside the placement groove 402 to complete the installation of the foam roll and the double-sided adhesive roll.

[0038] Next, the foam and one end of the double-sided adhesive are wrapped around the guide roller 311 and clamped together between the two clamping rollers 305. At the same time, the movable plate 302 and the limiting rod 303 are pushed to slide along the inside of the groove 301 by the extension and retraction characteristics of the support spring 304, adjusting the distance between the two clamping rollers 305. This facilitates the compression of foam and double-sided adhesive of different thicknesses, so that one end of the double-sided adhesive is stuck to the foam, improving convenience. In addition, the slider 309 is pushed to slide along the outside of the fixed rod 308 by the extension and retraction characteristics of the tension spring 310, so that the two guide rollers 311 move in opposite directions along the inside of the vertical frame 307, supporting and tightening the foam and double-sided adhesive to prevent wrinkles and ensure the bonding effect.

[0039] Next, the foam with double-sided tape attached is conveyed and wound around the outside of the take-up bar 407. At the same time, through the cooperation of the transmission bar 408, sprocket 409 and chain 410, power is transmitted to drive the take-up bar 407 to rotate and take up the attached foam. After the take-up is completed, the tray 411 is removed to make it easy to remove the foam roll from the take-up bar 407, which improves convenience.

[0040] Finally, when conveying the double-sided tape, the release paper at one end of the double-sided tape is wound around the outside of the winding rod 6. At the same time, the power is transmitted through the cooperation of the transmission wheel 7 and the belt 8, which drives the winding rod 6 to rotate and wind up the release paper. Thus, when conveying the double-sided tape, the release paper is peeled off simultaneously, ensuring the bonding effect.

[0041] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
