Description

Technical Field

[0001] This utility model relates to the field of shoe production technology, specifically to a shoe sole surface roughening machine. Background Technology

[0002] Roughening the sole is a core pre-treatment step in shoe manufacturing. It involves physically polishing the sole surface to create a uniformly rough texture, thereby improving adhesive adhesion and bonding strength. Statistics show that approximately 65% ​​of sole bonding failures originate from defects in the roughening process, and its effectiveness directly determines the durability and safety performance of the footwear.

[0003] Currently, the industry generally adopts the following two processing methods, but significant technical bottlenecks exist:

[0004] In manual operation mode, workers use handheld pneumatic grinding wheels for grinding, which is inefficient for roughing.

[0005] The semi-automatic mechanical device, which uses a fixed belt sander in conjunction with manual positioning, increases the processing speed of a single piece by 20%, but the manual pressing and sanding of the shoe sole results in low uniformity of roughening.

[0006] Based on this, the present invention designs a shoe sole surface roughening machine to solve the above problems. Utility Model Content

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6 This utility model provides a technical solution for a shoe sole surface roughening machine: A shoe sole surface roughening machine includes a frame 1, a roughening table 2 is provided in the middle of the frame 1, a transverse movement mechanism 3 is provided above the roughening table 2 and fixed on the frame 1, and a pressing mechanism 4 is installed on the displacement part of the transverse movement mechanism 3. The shoe sole placed on the roughening table 2 is pressed down by the pressing mechanism 4, and the roughening of the shoe sole can be achieved by coordinating with the movement of the transverse movement mechanism 3; a downwardly angled discharge slide plate 5 is installed at the end of the roughening table 2.

[0033] The roughing table 2 includes a roller conveyor table 21. A bearing seat 22 is provided on the side of the roller conveyor table 21. A roughing roller shaft 23 extending into the roller conveyor table 21 is rotatably connected to the bearing seat 22. A motor 24 is installed at the lower part of the frame 1. The output end of the motor 24 is connected to the roughing roller shaft 23 through a belt assembly.

[0034] Furthermore, a cleaning roller shaft 25 is provided on the roller conveyor 21, and the cleaning roller shaft 25 is connected to the roughening roller shaft 23 by a belt assembly; the belt assembly is a component that connects pulleys and belts for transmission, and the cleaning roller shaft 25 can reduce the residue of shoe sole debris through cleaning.

[0035] Furthermore, a dust collection hood 26 is provided below the sweeping roller 25 and the coarsening roller 23. The dust collection hood 26 is connected to an external vacuum cleaner. When the vacuum cleaner is turned on, it can absorb the debris from the coarsening and sweeping.

[0036] Furthermore, infrared sensors 27 are installed on both sides of the feed end of the roughing table 2. The infrared sensors 27 are electrically connected to the controller. After the infrared sensors 27 detect the shoe sole placed on the roughing table 2, they will activate the pressing mechanism 4 to press down, and then control the transverse mechanism 3 to move the pressing mechanism 4, thereby moving the shoe sole.

[0037] Furthermore, a vacuum head 28 is also installed on the roller conveyor 21. The vacuum head 28 includes a flat vacuum head body 281. A hollow rod 282 is installed on the roller conveyor 21 at the suction port of the vacuum head body 281. Suction ports 283 are evenly distributed on the top of the hollow rod 282. The vacuum head 28 is connected to an external vacuum cleaner. When the vacuum cleaner is turned on, the suction power is stronger because the openings of the vacuum head body 281 and the suction ports 283 are small. This results in a stronger adsorption force for the debris remaining on the soles of the shoes, which helps to improve the cleaning effect of the soles.

[0038] Furthermore, the pressing mechanism 4 includes a mounting frame 41 connected to the displacement part of the transverse mechanism 3. A cylinder 42 is mounted at the bottom of the mounting frame 41, and a lifting rod 43 that can slide up and down is mounted on the mounting frame 41. The telescopic end of the cylinder 42 is connected to the upper end of the lifting rod 43 through a rectangular block. An elastic pressing component 44 is mounted at the lower end of the lifting rod 43. The lifting and lowering of the telescopic end of the cylinder 42 can drive the lifting rod 43 to slide up and down, thereby driving the elastic pressing component 44 to rise and fall.

[0039] Furthermore, the elastic pressing component 44 includes a pressing plate 441. A fixed tube 442 connected and fixed to the lifting rod 43 is provided at the top center of the pressing plate 441. Elastic elements 443 are evenly installed on the pressing plate 441. The elastic element 443 is composed of a pressing rod that is thin in the middle and thick at both ends and a spring. The spring is sleeved on the pressing rod, and the upper and lower ends abut against the lower end of the pressing rod and the bottom of the pressing plate 441, respectively. When the pressing mechanism 4 presses down, the spring contracts and the pressing rod moves upward. Multiple sets of elastic elements 443 apply the same downward pressure to the sole, so that each point of the sole has downward pressure when it is being polished, which is beneficial to achieve uniform roughening of the sole.

[0040] Furthermore, the transverse mechanism 3 is a linear slide.

[0041] This sole roughening machine achieves high-efficiency operation through an integrated design of automated conveying, roughening, and cleaning. The specific process is as follows:

[0042] The sole is placed at the feed end of the roller conveyor 21. After the infrared sensor 27 detects that it is in place, the pressing mechanism 4 is activated. The cylinder 42 drives the lifting rod 43 to descend, and the elastic pressing component 44 presses down the sole. Then, it is driven forward by the transverse mechanism 3 to convey the sole to the top of the roughing roller (23).

[0043] The spring compression of the elastic pressing member 44, through the uniformly distributed elastic elements 443, can ensure that there are pressing points in all parts of the sole, making the polishing more uniform.

[0044] The motor 24 drives the coarsening roller 23 to rotate via the belt assembly, which rolls and coarses the sole of the shoe, while simultaneously driving the sweeping roller 25 to rotate synchronously to clean up residual debris.

[0045] The vacuum hood 26 and vacuum head 28 use the negative pressure of an external vacuum cleaner to suck away the debris from the coarse cleaning. When the sole of the shoe passes through the vacuum port 283 of the hollow rod 282, the suction is stronger, thereby enhancing the cleaning of the sole.

[0046] The roughened shoe soles are automatically slid out via the discharge slide plate 5 and proceed to the next process.
