Description

Technical Field

[0001] The utility model relates to the technical field of hole punching equipment, in particular to a reinforcing film hole punching production equipment. Background Art

[0002] There is a very serious problem when using the reinforcing films, butyl damping sheets and asphalt damping sheets on the current market at customers' locations: after being soaked in pre-treatment liquid and electrophoretic liquid and then baked for curing, the electrophoretic liquid, pre-treatment liquid, etc. penetrate into the interior of the reinforcing films and are baked for curing. Due to the rapid evaporation of water vapor, it cannot be discharged to the outside of the glass fiber cloth in time, resulting in a large number of bubbles during the baking process. The bubbles can lead to reinforcement failure, damping failure, abnormal noise during vehicle driving and other problems, which requires punching equipment to eliminate the bubbles.

[0003] After searching, for example, a utility model patent with Chinese patent number CN217434519U discloses a reinforcing film punching production equipment. The device is provided with a rotating shaft, a rotating wheel, a needle block, a fixing plate and a motor, so that uniform holes can be punched on the damping plate and the reinforcing film without affecting the performance, so that the reinforcing film can quickly discharge water vapor and eliminate bubbles during the production process, thereby solving the problem of using the reinforcing film on the car. However, the device is only provided with one punching mechanism, that is, it can only perform punching work with one density and cannot effectively eliminate bubbles. Therefore, a reinforcing film punching production equipment is proposed to solve the above problem. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 In this embodiment, a reinforcing rubber sheet punching production equipment includes a workbench 1, and fixed plates 2 are fixedly installed on the left and right sides of the top of the workbench 1, a coarse punching roller 3 is arranged between the two fixed plates 2, and a fine punching roller 4 is arranged on the front side of the coarse punching roller 3, two rubber rollers 5 are rotatably connected between the two fixed plates 2, a transmission mechanism 6 is arranged between the coarse punching roller 3 and the fine punching roller 4, and an adjustment mechanism 7 is arranged between the rubber roller 5 and the fixed plate 2.

[0024] Specifically, the left and right sides of the coarse piercing roller 3 and the fine piercing roller 4 are fixedly installed with a second rotating shaft 601, a pulley 602 is fixedly installed on the outside of the left second rotating shaft 601, and a belt 603 is connected for transmission between the two pulleys 602. A second motor 604 is fixedly installed on the left side of the left fixed plate 2. The second motor 604 drives the second rotating shaft 601 on the left side of the front side to rotate, which can drive the fine piercing roller 4 to rotate. With the cooperation of the pulley 602 and the belt 603, the second rotating shaft 601 on the rear side is driven to rotate, thereby driving the coarse piercing roller 3 to rotate.

[0025] Specifically, the left and right sides of the rubber roller 5 are fixedly installed with a first rotating shaft 701, the left and right ends of the first rotating shaft 701 are installed with connecting blocks 702, the left and right sides of the fixed plate 2 are fixedly installed with four mounting plates 703, the top of the right top mounting plate 703 is fixedly installed with a first motor 704, a threaded rod 705 is fixedly installed at the output shaft of the first motor 704, the external thread of the threaded rod 705 is connected with a threaded sleeve 706, a sliding rod 707 is fixedly installed between the two groups of mounting plates 703 on the left, and a sliding sleeve 708 is slidably connected to the sliding rod 707, the first motor 704 is controlled to drive the threaded rod 705 to rotate, so as to drive the threaded sleeve 706 to move up and down, thereby driving the rubber roller 5 to move up and down, the sliding rod 707 and the sliding sleeve 708 can limit the threaded sleeve 706 to prevent it from spirally rotating, so that the distance between the coarse piercing roller 3 and the fine piercing roller 4 and the rubber roller 5 can be adjusted according to the thickness of the reinforcing rubber sheet.

[0026] Specifically, sliding holes are provided on both the left and right side walls of the fixed plate 2, and one end of the first rotating shaft 701 away from the rubber roller 5 passes through the fixed plate 2 through the sliding hole, and the second rotating shaft 701 can move up and down in the sliding hole.

[0027] Specifically, a plurality of needle blocks are arranged on the outside of the coarse puncturing roller 3 and the fine puncturing roller 4. The density of the needle blocks on the coarse puncturing roller 3 is less than that on the fine puncturing roller 4. Because the puncturing densities of the coarse puncturing roller 3 and the fine puncturing roller 4 are different, the puncturing requirements of different densities of the reinforcing film can be met on one device, thereby improving the bubble removal effect.

[0028] When implementing, follow these steps:

[0031] 3) Finally, the reinforcing film first passes through the coarse punching roller 3 and the rear rubber roller 5 for preliminary punching, and then is transmitted to the fine punching roller 4 and the front rubber roller 5 for secondary punching. The punching requirements of reinforcing films with different densities can be completed on one device, the bubble removal effect is improved, and the reinforcing film can quickly discharge water vapor and eliminate bubbles during the production process.

[0032] In summary, the reinforcing film punching production equipment, by providing a coarse punching roller 3, a fine punching roller 4 and a transmission mechanism 6, can first use the coarse punching roller 3 to perform preliminary punching on the film, and then make the film pass through the fine punching roller 4 to punch holes. Because the punching densities of the coarse punching roller 3 and the fine punching roller 4 are different, the punching requirements of reinforcing films with different densities can be completed on one device, thereby improving the bubble removal effect. Moreover, by providing the transmission mechanism 6, the coarse punching roller 3 and the fine punching roller 4 can be driven to rotate at the same time, thereby reducing the manufacturing cost. By providing the adjustment mechanism 7, it is convenient to adjust the position of the rubber roller 5, so as to adjust the distance between the coarse punching roller 3 and the fine punching roller 4 and the rubber roller 5, so as to realize punching of reinforcing films of different thicknesses, thereby solving the problem of limited punching effect of the comparative device.
