DETAILED DESCRIPTION

[0023] First of all, it should be pointed out that in the different described embodiments, the same parts are provided with the same reference numerals or the same component names, wherein the disclosure contained in the entire description can be transferred to the same parts with the same reference numerals or the same component names. Selected positional descriptions in the description, such as top, bottom, lateral, etc., also refer to the directly described and shown figures and are transferred to the new positions in the case of a change in position.

[0024] Embodiment: A precision double-sided rubber cloth laminating machine, such as Figure 1-Figure 4As shown, it includes a frame 1, a fixed plate 2, a roller 3, a support plate 4, a guide cylinder 5 and a blanking frame 6. The frame 1 is provided with two groups of the fixed plates 2 above and below, and the two fixed plates 2 in each group are symmetrically distributed front and back. The two fixed plates 2 in each group are symmetrically connected to the frame 1 by welding. The roller 3 is rotatably connected between the two fixed plates 2 in each group. The support plates 4 are connected to the support plates 4 by welding above and below the frame 1. The left ends of the two support plates 4 are located between the two rollers 3 in each group. The guide cylinder 5 is rotatably connected to the right side of the frame 1 above and below. The surface of each roller 3 and the two guide cylinders 5 is smooth and not easy to stick to rubber. The two guide cylinders 5 are located behind the two support plates 4. The top between the two fixed plates 2 in each group is connected to the blanking frame 6 by screw installation. The blanking opening of the blanking frame 6 located above the frame 1 is arranged on the right side of the roller 3, and the blanking opening of the blanking frame 6 located below the frame 1 is arranged on the left side of the roller 3.

[0025] When it is necessary to bond the double-sided rubber cloth, the staff pours the rubber into the blanking frame 6, and then the double-sided rubber cloth is first pulled between the two rollers 3 located in the upper group and passes through. After passing through, the rubber in the upper blanking frame 6 flows to the upper surface of the double-sided rubber cloth, and then the double-sided rubber cloth is pulled around the guide cylinder 5 to turn the double-sided rubber cloth over. When it is pulled through between the two rollers 3 located in the lower group and before passing through, the rubber in the upper blanking frame 6 flows to the upper surface of the turned-over double-sided rubber cloth, and then passes through the two rollers 3 to bond the two surfaces of the double-sided rubber cloth with the rubber.

[0026] like Figure 1 and Figure 4 As shown, it also includes a fixed block 7 and a scraper 8. The middle part of each group of two fixed plates 2 is connected to the fixed block 7 by screw installation. The two fixed blocks 7 located above the frame 1 are both arranged on the right side of the drum 3. The two fixed blocks 7 located below the frame 1 are both arranged on the left side of the drum 3. The scraper 8 is connected to the front and rear adjacent fixed blocks 7 by screw installation. The scraper 8 is arc-shaped.

[0027] To prevent uneven thickness of rubber applied to the double-sided rubber cloth, when the rubber in the unloading frame 6 flows to the surface of the double-sided rubber cloth, the double-sided rubber cloth will pass through the scraper 8. Since the distance between the scraper 8 and the support plate 4 is fixed, the scraper 8 can scrape off the excess rubber.

[0028] like Figure 1 and Figure 5As shown, it also includes a support rod 9, a motor 10 and a rotating shaft 11. The left end surface of the fixed plate 2 located at the rear side below the frame 1 is connected to the support rod 9 by screw installation. The rear side of the support rod 9 is connected to the motor 10 by screw installation. The output shaft of the motor 10 passes through the support rod 9 and is rotatably connected to the rotating shaft 11.

[0029] After the staff pulls the double-sided rubber cloth out from the two rollers 3 below, the staff winds the double-sided rubber cloth around the rotating shaft 11, and then starts the motor 10 to drive the rotating shaft 11 to rotate, so that the double-sided rubber cloth is automatically wound into a roll. After the roll is formed, the motor 10 is turned off, the rotating shaft 11 stops rotating, and the staff cuts the double-sided rubber cloth and pushes the rolled double-sided rubber cloth out from the front end, and then continues to wind the cut end of the double-sided rubber cloth around the rotating shaft 11, and then starts the motor 10 to roll it again.

[0030] like Figure 5 and Figure 6 As shown, it also includes a sleeve rod 12, a material stopping rod 13, a block 14 and an elastic member 15. The left end surface of the fixed plate 2 on the front side below the frame 1 is connected to the sleeve rod 12 by screw mounting. An L-shaped groove is provided on the sleeve rod 12. The inner side of the sleeve rod 12 is slidably connected to the material stopping rod 13. The right side of the material stopping rod 13 is slidably connected to the block 14, and the block 14 slides in the L-shaped groove of the sleeve rod 12. The elastic member 15 is connected between the material stopping rod 13 and the sleeve rod 12.

[0031] In order to prevent the double-sided rubber cloth from slipping out from the front end of the rotating shaft 11 when it is rolled, the front end of the rotating shaft 11 can be blocked by the blocking rod 13. When the rolled double-sided rubber cloth needs to be removed, the blocking rod 13 is first pushed to move to the right. At this time, the elastic member 15 is compressed and deformed, and the clamping block 14 slides to the right along the L-shaped groove of the sleeve rod 12 to the terminal end, and then the clamping block 14 is pushed to slide downward along the L-shaped groove of the sleeve rod 12, which can block the blocking rod 13 to prevent it from resetting and moving to the left to affect the removal of the rolled double-sided rubber cloth from the rotating shaft 11. After removal, the clamping block 14 is pushed to slide upward along the L-shaped groove of the sleeve rod 12, and the blocking rod 13 and the clamping block 14 are reset by the elastic member 15 and move to the left to reset.

[0032] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
