[0026] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0027] Reference Figure 1 As shown, a rubber sleeve efficient circulation feeding structure includes a base 1, an automatic discharging component 2 is provided at the upper end of the base 1, a conveying component 3 is provided at the rear end of the automatic discharging component 2, a transfer and straightening component 4 is provided at the left end of the conveying component 3, a rotary processing table 5 is provided at the left end of the transfer and straightening component 4, the lower end of the rotary processing table 5 is rotatably connected to the upper end of the base 1, and a plurality of evenly distributed positioning grooves 6 are opened through the upper end of the rotary processing table 5.

[0028] Furthermore, the positioning groove 6 farthest from the transfer and straightening assembly 4 is located directly below the assembly mechanism. The processing position can be switched by rotating the rotary processing table 5, and the rotation of the rotary processing table 5 is driven by an external driving device.

[0029] Reference Figure 2As shown, the automatic discharging assembly 2 includes a storage box 201, the lower end of the storage box 201 is fixedly connected to the upper end of the base 1, the inner bottom end of the storage box 201 is fixedly connected to a ramp 202, and three evenly distributed guide blocks 203 are fixedly connected between the left and right inner walls of the ramp 202 and located on the rear side of the ramp 202, and a push block 208 is slidably connected between two adjacent guide blocks 203, and the inner bottom end of the storage box 201 is located on the rear side of the ramp 202 and is fixedly installed with a lifting cylinder 204, and the output end of the lifting cylinder 204 is fixedly connected to a lifting plate 205, which is slidably connected between the storage box 201 and the ramp 202, and the upper end of the lifting plate 205 is fixedly connected to the lower end of the push block 208, and a discharge port 206 is provided through the upper end of the rear end of the storage box 201 near the rear guide block 203, and a baffle 207 is fixedly connected between the left and right inner walls of the storage box 201.

[0030] Furthermore, the storage box 201 contains a plastic sleeve 8. The upper ends of the push block 208 and the guide block 203 are inclined surfaces. The thickness of the push block 208 is the same as the diameter of the plastic sleeve 8. The three guide blocks 203 and the two push blocks 208 are distributed in a gradually rising step-like manner from front to back. The plastic sleeve 8 inside the storage box 201 will gradually slide downward along the surface of the inclined platform 202 and fall onto the guide block 203 on the front side. At this time, the lifting cylinder 204 drives the lifting plate 205 to reciprocate in the vertical direction, which can drive the push block 208 to fall on the front guide block 2 03, the plastic sleeve 8 is conveyed to the upper end of the rear guide block 203, forming a stepped conveying. Since the thickness of the push block 208 is the same as the diameter of the plastic sleeve 8, only when the cylindrical plastic sleeve 8 is in a horizontal state, the push block 208 can make sufficient contact with it, thereby pushing the plastic sleeve 8 to move upward. The plastic sleeve 8 can be screened through the stepped conveying method, so that the plastic sleeve 8 is finally sent out from the discharge port 206 in a horizontal state. The number of steps can be increased according to actual use, and the accuracy of screening can be improved by increasing the number of steps.

[0031] Reference Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the conveying assembly 3 includes a first bracket 301 and a second bracket 302 fixedly connected to the upper end of the base 1, a conveyor belt 303 is arranged between the first bracket 301 and the second bracket 302, a positioning plate 304 is fixedly connected on the side of the first bracket 301 and the second bracket 302 away from the storage box 201, and the front ends of the first bracket 301 and the second bracket 302 are located on the right side of the positioning plate 304 and are penetrated by a grabbing opening 305.

[0032] Furthermore, the plastic sleeve 8 sent out from the discharge port 206 in a horizontal state will fall on the upper end of the conveyor belt 303 and be transported toward the positioning plate 304 through the conveyor belt 303 until it abuts against the positioning plate 304. A contact sensor is provided on the side of the positioning plate 304 abutting against the plastic sleeve 8 for sensing whether there is a plastic sleeve 8 here. If the plastic sleeve 8 is not sensed, the conveyor belt 303 continues to operate. If the contact sensor senses that there is a plastic sleeve 8 on one side of the positioning plate 304, the conveyor belt 303 stops running and waits for the transfer straightening component 4 to grab the plastic sleeve 8 abutting against the positioning plate 304.

[0033] Furthermore, limit plates 7 are fixedly connected between the storage box 201 and the first bracket 301 on both sides of the discharge port 206. The limit plates 7 can prevent the plastic sleeve 8 from sliding off from both sides of the discharge port 206 when it is sent out from the discharge port 206.

[0034] Reference Figure 6 As shown, the transfer and straightening assembly 4 includes a guide rail 401, which is fixedly connected to the upper end of the base 1 through a support frame, and a slide groove 402 is provided through the upper end of the guide rail 401, and the inner rotation of the slide groove 402 is connected to a screw rod 403, and the outer surface of the screw rod 403 is threadedly connected to a sliding seat 404, and the lower end of the sliding seat 404 is fixedly installed with four evenly distributed electric telescopic rods 405, and the output end of the electric telescopic rod 405 is fixedly connected to a fixed frame 406, and the inner side of the fixed frame 406 is rotatably connected to a rotating seat 407, and the inner side of the rotating seat 407 is fixedly installed with a thumb cylinder 408, and the rear end of the fixed frame 406 is fixedly installed with a servo motor 409 for driving the rotating seat 407 to rotate.

[0035] Furthermore, the rotation of the screw rod 403 is driven by an external motor, the initial position of the thumb cylinder 408 is located just above the grabbing opening 305, and there is a plastic rubber sleeve 8 on one side of the positioning plate 304. The electric telescopic rod 405 pushes the fixing frame 406 downward, so that the two clamping claws of the thumb cylinder 408 are located on both sides of the plastic rubber sleeve 8 and aligned with the two grabbing openings 305, and then the clamping claws of the thumb cylinder 408 gradually shrink to clamp the plastic rubber sleeve 8. After the plastic rubber sleeve 8 is clamped and fixed, the electric telescopic rod 405 drives the fixing frame 406 to move downward. 6 is reset, and at the same time, the motor drives the screw rod 403 to rotate, so that the sliding seat 404 drives the thumb cylinder 408 to move above the position of the rotary processing table 5, and then the servo motor 409 drives the thumb cylinder 408 to rotate 90°. At this time, the plastic sleeve 8 is in a vertical state and is located directly above the positioning groove 6 on the side closest to the transfer and straightening component 4. Then, the electric telescopic rod 405 will push the fixing frame 406 downward to place the plastic sleeve 8 in the positioning groove 6. At the same time, the clamping claw of the thumb cylinder 408 is loosened, completing the straightening and placement of the plastic sleeve 8.

[0036] Working principle: When in use, place the plastic sleeve 8 in the storage box 201, then start the lifting cylinder 204, and through the reciprocating motion of the lifting cylinder 204, gradually drive the push block 208 to push the plastic sleeve 8 to the guide block 203 on the rear side, and the plastic sleeve 8 that falls on the guide block 203 on the rear side will be sent out from the discharge port 206 in a horizontal state and fall on the conveyor belt 303, and the conveyor belt 303 will transport the plastic sleeve 8 in the direction of the positioning plate 304. When the plastic sleeve 8 arrives at the positioning plate 304, the contact sensor on the positioning plate 304 senses its presence and stops the operation of the conveyor belt 303 and the lifting cylinder 204. At this time, the electric telescopic rod 405 pushes the fixed frame 406 to move down, and adjusts the position of the clamping claws of the thumb cylinder 408 to both sides of the plastic sleeve 8. Then, the clamping claws of the thumb cylinder 408 gradually shrink to clamp the plastic sleeve 8, and then the electric telescopic rod 405 drives the fixing frame 406 to reset, and at the same time, the motor drives the screw rod 403 to rotate, driving the thumb cylinder 408 with the plastic rubber sleeve 8 to move to the top of the rotary processing table 5, and then the thumb cylinder 408 rotates 90° to make the plastic rubber sleeve 8 become vertical, facing the positioning groove 6 of the rotary processing table 5, and then the electric telescopic rod 405 pushes the fixing frame 406 to move down, and places the plastic rubber sleeve 8 in the positioning groove 6, and the clamping claw of the thumb cylinder 408 is released to complete the placement of the plastic rubber sleeve 8. After the plastic rubber sleeve 8 is successfully placed, the rotary processing table 5 rotates a fixed angle to rotate the empty positioning groove 6 to the placement position, and then the above process is repeated. As the cycle proceeds, the rotary processing table 5 will transfer the positioning groove 6 with the plastic rubber sleeve 8 to the assembly area, and the plastic rubber sleeve 8 is assembled through the assembly mechanism. The whole process continues, which can realize efficient cyclic loading of the plastic rubber sleeve 8.
