[0002] Rubber soles are widely used in sports shoes and other footwear due to their good wear resistance, anti-skid, waterproof, elastic and strong comfort. In the process of preparing rubber soles, it is necessary to go through material selection, mold design, sole molding, burr grinding and overall coloring to form the finished rubber soles;

[0003] Burr grinding refers to the grinding operation on the already formed sole, thereby removing the burrs on the rubber sole during the production process to form a finished sole with a regular surface. In the traditional manufacturing process, before burr grinding, the staff needs to use manual or mechanical equipment to test the molding thickness of the rubber sole in turn to ensure that the thickness of the rubber sole meets the production requirements before performing subsequent grinding operations. However, the efficiency of completing the inspection work by setting up a separate inspection link is low, which affects the processing efficiency. Summary of the invention

[0027] like Figure 1-3 , Figure 5 and Figure 8 As shown:

[0028] A grinding device includes a processing table 101, a fixed rod 301 and a detection part 204, wherein the processing table 101 is provided with a plurality of air holes 102, the detection part 204 is located on the upper side of the processing table 101, a moving part 302 is slidably connected to the fixed rod 301, a contact part 303 is slidably connected to the moving part 302, a check rod 304 is slidably connected to the contact part 303, a slider 502 is connected to the contact part 303, a grinding wheel 504 is rotatably connected to the slider 502, a first compression spring is fixedly connected between the moving part 302 and the contact part 303, and the first compression spring can The slider 502 is fixed with a first motor, the output shaft of the first motor is fixed with a gear, the grinding wheel 504 is fixed with a gear ring, the gear and the gear ring are meshed, and a vacuum pump is detachably connected to the lower side of the processing table 101 by bolts, and the vacuum pump is located opposite to the multiple air holes 102. The fixed rod 301 is fixed with a second motor, the output shaft of the second motor is fixed with a first lead screw, and the first lead screw is threadedly connected to the moving part 302. The contact part 303 is fixed with a first electric push rod capable of pushing the inspection rod 304 to slide.

[0029] The formed rubber sole is placed in the area of ​​the multiple air holes 102 on the processing table 101, and then the vacuum pump is started to form negative pressure by using the vacuum pump, so that the rubber sole can be firmly placed on the processing table 101, and then the moving part 302 is operated to slide on the fixed rod 301, so that the contact part 303 gradually approaches the area where the rubber sole is located. When the contact part 303 moves to contact with the rubber sole, as the moving part 302 continues to slide, the contact part 303 on the moving part 302 overcomes the elastic force of the first compression spring and slides upward adaptively until the contact part 303 moves to just be able to contact with the upper surface of the sole Position, during this process, the slider 502 will follow the contact part 303 to move to a suitable height, and then the grinding wheel 504 will continue to rotate on the slider 502, and the moving part 302 will continue to slide, and then the rotating grinding wheel 504 will be used to grind the rubber sole to complete the burr removal effect. At the same time, the contact part 303 is slidably arranged on the moving part 302, so that when the contact part 303 encounters a sole of any thickness, it can be ensured that the contact part 303 is against the upper side of the sole, thereby ensuring that the grinding wheel 504 can be at a suitable height, so that the device can perform grinding and burr removal operations on soles of different thicknesses;

[0030] After the contact portion 303 moves to a position where it can just contact the upper surface of the sole, the inspection rod 304 can be operated to slide on the contact portion 303. At this time, if the thickness of the rubber sole meets the production requirements, the inspection rod 304 should just be able to contact the upper side of the detection portion 204 after sliding. On the contrary, if after sliding the inspection rod 304, the inspection rod 304 cannot normally contact the upper side of the detection portion 204, and the height of the inspection rod 304 is higher or lower than the upper side of the detection portion 204, it proves that the thickness of the rubber sole does not meet the actual production requirements, and then the rubber sole needs to be supplemented with processing operations to ensure the factory effect of the finished product. That is, the equipment can not only automatically grind the rubber sole, but also detect the thickness molding of the rubber sole, which brings convenience to actual use.

[0031] like Figure 2 As shown:

[0032] It also includes a sliding sleeve 203 , on which a detection portion 204 is slidably connected, and a second compression spring is fixedly connected between the sliding sleeve 203 and the detection portion 204 .

[0033] When the contact portion 303 moves to a position where it can just contact the upper surface of the sole and the inspection rod 304 is operated to slide on the contact portion 303, if the height of the inspection rod 304 is lower than the uppermost position of the detection portion 204 at this time, the sliding inspection rod 304 will press against the front side of the detection portion 204, and then as the inspection rod 304 continues to slide, the detection portion 204 will slide on the sliding sleeve 203 to overcome the elastic force of the second compression spring. At this time, by monitoring the sliding condition of the detection portion 204, it is possible to check whether the contact portion 303 is at a suitable height, thereby achieving the effect of checking the thickness of the rubber sole;

[0034] Example 1 of monitoring the sliding condition of the detection unit 204:

[0035] A plurality of scale marks may be provided on the detection part 204. When the detection part 204 slides on the sliding sleeve 203, the scale marks corresponding to the sliding sleeve 203 may change, so that after arriving at the site, the staff can clearly observe the sliding condition of the detection part 204 through the sliding of the detection part 204 and the change of the scale marks, thereby achieving the effect of monitoring the sliding condition of the detection part 204.

[0036] Example 2 of monitoring the sliding condition of the detection unit 204:

[0037] A displacement sensor is connected to the sliding sleeve 203 by screwing bolts into the detection part 204, and the moving end of the displacement sensor is fixed to the detection part 204 by tightening the bolts. When the detection part 204 slides subsequently, the moving end of the displacement sensor can move. During this process, the displacement sensor can convert the signal into an electrical signal for transmission, thereby achieving the effect of automatically monitoring the sliding condition of the detection part 204.

[0038] like Figure 2-3 As shown:

[0039] It also includes an oblique rod 205 fixedly connected to the detection portion 204 .

[0040] After sliding the inspection rod 304, if the inspection rod 304 just happens to be in contact with the upper side of the detection part 204, the inspection rod 304 is continuously slid until the inspection rod 304 is in contact with the oblique rod 205, and then the moving part 302 is continuously operated to slide on the fixed rod 301 to move the slider 502 and complete the subsequent grinding operation. In this process, since the oblique rod 205 is set as an inclined surface, the inspection rod 304 will gradually push the detection part 204 to slide to the left on the sliding sleeve 203 to overcome the elastic force of the second compression spring during the sliding of the moving part 302, and then by monitoring whether the detection part 204 has a gradually increasing sliding situation, it is possible to further accurately determine whether the inspection rod 304 is in a position where it can just contact the upper surface of the detection part 204, thereby accurately determining whether the thickness of the rubber sole meets the production requirements, and further improving the process of automatic detection using displacement sensors.

[0041] like Figure 3 As shown:

[0042] The detection unit 204 further includes a rotating plate 206 rotatably connected to the detection unit 204 , and a torsion spring is fixedly connected between the rotating plate 206 and the detection unit 204 .

[0043] After the inspection rod 304 is slid, if the height of the inspection rod 304 is higher than the height of the detection part 204, that is, the inspection rod 304 is at the overlapped position with the rotating plate 206, the continuously sliding inspection rod 304 will push the rotating plate 206 to rotate on the detection part 204, and then by monitoring the rotation of the rotating plate 206, whether the thickness of the rubber sole meets the production requirements can be further accurately inspected to improve the inspection work;

[0044] Example 1 of monitoring the rotation of the rotating plate 206:

[0045] An angle sensor is connected to the detection part 204 by tightening bolts on the detection part 204, and the rotating end of the angle sensor is fixedly connected to the rotating plate 206 by tightening bolts. When the rotating plate 206 rotates, the angle sensor can convert the rotation into an electrical signal for transmission, thereby completing the monitoring effect of the rotation of the rotating plate 206;

[0046] Example 2 of monitoring the rotation of the rotating plate 206:

[0047] A rotary encoder is connected to the detection part 204 by tightening bolts on the detection part 204, and the output shaft of the rotary encoder is fixedly connected to the rotating plate 206. When the rotating plate 206 rotates, the output shaft of the rotary encoder will be driven to move synchronously. During the rotation of the output shaft, a series of electrical pulse signals will be output. The rotation status of the rotating plate 206 can be calculated through the electrical pulse signals, and the rotation status of the rotating plate 206 can also be monitored.

[0048] like Figure 2 As shown:

[0049] The vertical rod 201 is provided with a plurality of scale grooves 202 . A sliding sleeve 203 is slidably connected to the vertical rod 201 . The sliding sleeve 203 is provided with a fixing threaded hole.

[0050] In actual use, the staff can operate the sleeve 203 to slide on the vertical rod 201 according to different actual production needs, and then change the height of the sleeve 203. After sliding the sleeve 203 to a suitable height, the sleeve 203 is fixed by screwing a bolt into the fixed threaded hole, and then the moving part 302 is operated to slide, and subsequent thickness detection and burr grinding operations are performed. That is, through the setting of the sliding sleeve 203, the equipment can adjust the qualified detection range according to different production needs, thereby expanding the scope of application of the equipment.

[0053] When the grinding wheel 504 is used for grinding, the movable part 302 can be made to slide back and forth on the fixed rod 301, so that the grinding wheel 504 gradually passes through the area where the rubber sole is located. At the same time, during multiple grinding operations, the slide 501 can be operated to gradually slide from top to bottom on the contact part 303, thereby gradually increasing the grinding depth to further improve the grinding effect. During this process, the slider 502 can be operated to slide back and forth left and right on the slide 501, so that the grinding wheel 504 can perform a comprehensive grinding operation on the area where the rubber sole is located.

[0054] like Figure 4 , Figure 6 , Figure 7 and Fig. 9 As shown:

[0055] It also includes a connecting frame B306 fixedly connected to the contact portion 303, a shielding portion B402 is slidably connected to the contact portion 303, an inclined block 403 is fixedly connected to the lower side of the shielding portion B402, an arc portion 503 is fixedly connected to the slider 502, a third compression spring is fixedly connected between the contact portion 303 and the shielding portion B402, the third compression spring can provide a rightward thrust for the shielding portion B402, and a container A that passes through the connecting frame B306 is detachably connected to the connecting frame B306 by bolts, the container A is filled with red pigment powder, and the shielding portion B402 can shield the lower side of the connecting frame B306.

[0056] When it is detected that the rubber sole is too thick, the slider 502 can be operated to slide to the position where the arc portion 503 is opposite to the lower side of the oblique block 403, and then the slide 501 can be slid upward to make the arc portion 503 contact the lower side of the oblique block 403, and then the slide 501 can be continuously slid upward to make the arc portion 503 press the oblique block 403 so that the oblique block 403 overcomes the elastic force of the third compression spring and slides, thereby sprinkling the red pigment powder onto the upper side of the rubber sole, and then marking the rubber sole with excessive thickness, so that the staff can quickly understand the non-compliance of the rubber sole after taking it, which brings convenience to the subsequent supplementary processing operations.

[0057] like Figure 4 As shown:

[0058] It also includes a connecting frame A305 fixedly connected to the contact portion 303, a shielding portion A401 is slidably connected to the connecting frame A305, a fourth compression spring is fixedly connected between the connecting frame A305 and the shielding portion A401, the fourth compression spring can provide a rightward elastic force for the shielding portion A401, and a container B penetrating from top to bottom is detachably connected to the connecting frame A305 by bolts, the container B is filled with green pigment powder, and the shielding portion A401 can shield the lower side of the connecting frame A305.

[0059] When it is detected that the rubber sole is too thin, the slider 502 can be operated to slide to the position where the arc portion 503 is directly opposite the lower side of the blocking portion A401, and then the slide 501 can be slid upward to make the arc portion 503 push the blocking portion A401 and then sprinkle green paint, thereby marking the rubber sole with too thin a thickness with the green paint.

[0060] like Figure 1 As shown:
