[0023] The present invention will be further described below in conjunction with the accompanying drawings:

[0024] like Figure 1-5 As shown, a rubber ball peeler comprises a bracket 1, wherein a grinding ball cylinder is installed in the middle of the bracket 1, wherein the grinding ball cylinder consists of an outer cylinder 3 and an inner rotor 10, wherein the inner wall of the outer cylinder 3 and the surface of the inner rotor 10 are smeared or covered with abrasive, a motor 12 is connected to the inner rotor 10 through a rotating shaft 6, and drives the inner rotor to rotate in a positive direction, hollow shafts 11 are sleeved at both ends of the inner rotor, and the hollow shaft 11 is connected to the end covers 14 on both sides of the outer cylinder through flanges 9, a reducer 13 drives the hollow shaft on the right side to drive the outer cylinder to rotate in the opposite direction, and a speed regulator 4 controls the rotation speed of the hollow shaft.

[0025] The speed adjuster 4 is placed on the supporting table 2 of the bracket. The speed adjuster 4 structure includes a U-shaped shell 41, a U-shaped part 42 is provided in the middle of the U-shaped shell 41, a limiting wheel 43 passes through the groove of the U-shaped part 42 through an axis 49, the limiting wheel 43 is in parallel contact with the hollow shaft, both ends of the axis 49 pass through the outside of the U-shaped shell 41 and are fixed by nuts 44, the axis 49 can move back and forth in the track groove 47 of the U-shaped shell 41, the bottom of the U-shaped part 42 is connected with a bolt 45, and the bolt 45 extending out of the U-shaped shell 41 is provided with an adjusting nut 46.

[0026] The left and right hollow shafts 11 are placed on the support table 2 through the bearing seat 5. The two ends of the bearing seat 5 are fixed to the support table 2 through fixing bolts 8. The two ends of the inner rotor 10 are placed in the left and right hollow shafts 11 through bearings.

[0027] The outer cylinder 3 is provided with a rubber ball delivery port, and the rubber ball delivery port is provided with a cover.

[0028] The output shaft of the motor 12 transmits power to the inner rotor 10 through a conveyor belt, and the output shaft of the reducer transmits power to the hollow shaft 11 through a conveyor belt.

[0029] An inner rotor end push block 15 is also provided in the hollow shaft on the right side. The push block 15 is connected to a lead screw push rod 16. The lead screw push rod 16 penetrates a limit block 17 through a thread, so as to effectively adjust the displacement of the rotor shaft 101.

[0030] Working principle:

[0031] The rubber balls are placed in the grinding ball cylinder, and the inner rotor is driven by the motor to realize forward rotation. The reducer drives the hollow shaft to make the outer cylinder reverse. The rubber balls are placed on the inner wall of the outer cylinder. The speed regulator 4 controls the hollow shaft so that when the outer cylinder reverses, the rubber balls can be centrifuged to the top and fall onto the inner rotor (that is, the centrifugal force of the rubber balls is less than the gravity of the rubber balls). When the inner rotor rotates forward, the falling rubber balls change direction to achieve uniform grinding. The problems of rubber ball adhesion and uneven grinding under centrifugation can be solved through forward and reverse rotation. Under the control of forward and reverse rotation and speed regulator 4, the diameter tolerance of the rubber balls after peeling or grinding can be controlled within ±0.2mm. The inner rotor is composed of a rotor shaft 101 and a grinding roller 102. The grinding roller is coated or covered with abrasive. The outer diameter of the inner rotor is 36mm. Specific implementation method:

[0033] Open the cover of the rubber ball delivery port on the outer cylinder 3, put a number of rubber balls into the outer cylinder, and seal it with the cover, turn on the motor 12, the output wheel of the motor 12 is connected to the driven wheel 7 through a conveyor belt, the driven wheel 7 is connected to the rotating shaft 6, the rotating shaft 6 and the inner rotor 10 are connected by reverse bolts, when the rotating shaft and the inner rotor 10 rotate forward, the two can be connected more firmly, at this time the rotating shaft 6 drives the inner rotor to rotate forward, at the same time, the reducer 13 also transmits the reverse rotation power to the hollow shaft on the right through the output shaft, the hollow shaft 11 is connected to the outer cylinder 3 by a flange, so that the outer cylinder 3 rotates in the opposite direction, so that the rubber balls can be peeled or ground in the ball grinding cylinder.

[0034] The above embodiment is preferred. In order to ensure a good peeling or grinding effect, a speed adjuster 4 is arranged in parallel at the right hollow shaft position. The U-shaped shell 41 of the speed adjuster 4 is welded or fixed on the support table 2. The limit wheel 43 of the speed adjuster 4 contacts the hollow shaft to control the speed of the hollow shaft to reduce. The specific method is to rotate the handle 48 clockwise so that the bolt 45 pushes the U-shaped part 42 to move forward, so that the limit wheel 43 contacts the hollow shaft, and then the speed of the hollow shaft can be reduced. The U-shaped part 42 moves forward by the shaft 49 along the track slot 47. After determining the appropriate speed, the bolt 45 is fixed by two adjusting nuts 46. Similarly, on this basis, if it is considered that the speed of the hollow shaft is too low, the handle 48 can be rotated counterclockwise so that the bolt 45 pulls the U-shaped part 42 to move backward.

[0035] The above embodiment is preferred. In order to prevent the inner rotor from shifting to the right as a whole, causing the right side surface of the grinding ball cylinder to rub against the bracket, an end push block 15 is installed in the hollow shaft on the right side. The push block 15 is connected to the screw push rod 16. The screw push rod 16 penetrates the limit block 17 through a thread, that is, the screw push rod 16 is rotated so that the push block 15 moves the inner rotor to the left as a whole.

[0036] Preferably, in the above embodiment, the cover is hinged to the rubber ball delivery port by a hinge.

[0037] The above are all preferred embodiments of the present invention. For ordinary technicians in this technical field, without departing from the principle of the present invention, various equivalent modifications to the present invention belong to the protection scope of the claims attached to this application.
