The roller drop control cylinder two and the roller drop control cylinder one are sequentially arranged on the loading platform along the direction in which the chamfered roller will drop. The loading lifting cylinder is used to lift the V-shaped block groove to the bottom of the dropping end of the loading platform.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] The purpose of this invention is to provide a dual-station rubber roller inner chamfering device to solve the problems existing in the prior art. It features a simple structure, high degree of automation, and can greatly reduce labor intensity and improve production efficiency.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] like Figures 1-9 As shown, the present invention provides a dual-station rubber roller inner chamfering device, comprising:

[0034] The feeding mechanism includes a feeding lifting cylinder 1, a feeding platform, a V-shaped block groove 5, and a rubber roller dropping control cylinder. The rubber roller dropping control cylinder controls the rubber roller to be chamfered on the feeding platform to fall into the V-shaped block groove 5. The V-shaped block groove 5 is mounted on the feeding lifting cylinder 1. The cylinder seat of the feeding lifting cylinder 1 is mounted on the feeding screw 2 of the device frame and can move left and right along the device frame.

[0035] The positioning mechanism includes a positioning cylinder 6, a retraction cylinder 7, a positioning plate 8, and a tensioning sleeve 13 mounted on a positioning seat 12. The positioning seat 12 is mounted on the device frame. The positioning cylinder 6 and the retraction cylinder 7 control the extension and retraction of the positioning plate 8. One end of the chamfering roller is mounted on the tensioning sleeve 13 and rotates with the tensioning sleeve 13.

[0036] The feeding mechanism includes a feeding cylinder 10 and a feeding pusher plate 9. The feeding cylinder 10 is used to drive the feeding pusher plate 9 to move and push the rubber roller to be chamfered into the tension sleeve 13.

[0037] The tensioning mechanism includes a tensioning cylinder 11 and a tensioning shaft 14. The tensioning cylinder 11, which is mounted on the device frame, is used to drive the tensioning shaft 14 into the tensioning sleeve 13.

[0038] The chamfering mechanism is provided on the frame of the device at positions corresponding to the two ends of the two rubber rollers to be chamfered. The chamfering mechanism includes a feed screw, a tool holder 16 and a cutter head. The feed screw is used to drive the tool holder 16 to feed or retract, and the cutter head performs internal chamfering on the rubber rollers to be chamfered.

[0039] In one embodiment, the roller drop control cylinder includes roller drop control cylinder 3 and roller drop control cylinder 4. The roller drop control cylinder 4 and roller drop control cylinder 3 are arranged sequentially on the loading platform along the direction in which the chamfered roller will drop. The loading lifting cylinder 1 is used to lift the V-shaped block groove 5 to the bottom of the dropping end of the loading platform.

[0040] In one embodiment, the V-shaped block groove 5 has two material slots. When the feeding lifting cylinder 1 is in the lifting state, the second roller dropping control cylinder 4 is pressed down, and the first roller dropping control cylinder 3 is released, a roller to be chamfered will fall into the first material slot of the V-shaped block groove 5. Then, the first roller dropping control cylinder 3 is pressed down, and the second roller dropping control cylinder 4 is released, so the roller to be chamfered will roll to the first roller dropping control cylinder 3 and be blocked. The feeding screw 2 drives the V-shaped groove to move forward so that the second material slot is at the discharge port. The second roller dropping control cylinder 4 is pressed down, and the first roller dropping control cylinder 3 is released, so a roller to be chamfered will fall into the second material slot of the V-shaped block groove 5. After both material slots are full, a photoelectric sensor signal is transmitted, and the feeding screw 2 starts to move to send the V-shaped groove to the chamfering mechanism.

[0041] In one embodiment, the two ends of the ejector cylinder 7 are fixedly connected to the positioning seat 12 and the L-shaped connecting plate, respectively; the cylinder seat of the positioning cylinder 6 is fixed on the positioning seat 12, and the telescopic end of the positioning cylinder 6 is used to push out the L-shaped connecting plate, thereby driving the positioning plate 8 to move forward; the bottom end of the L-shaped connecting plate is fixed on the positioning platform, the positioning platform moves back and forth along the positioning seat 12, and two positioning plates 8 are symmetrically arranged at the front end of the positioning platform; the lower end of the positioning plate 8 is provided with a groove that matches the main shaft of the tensioning sleeve 13, and the groove does not affect the rotation of the main shaft of the tensioning sleeve 13.

[0042] In one embodiment, the feeding cylinder 10 is mounted on the device frame via a fixed base. The telescopic end of the feeding cylinder 10 is connected to the feeding push plate 9. The feeding cylinder 10 drives the feeding push plate 9 to push the rubber roller to be chamfered from the V-shaped block groove 5 into the tension sleeve 13 and is blocked by the positioning plate 8.

[0043] In one embodiment, the tension cylinder 11 and the feeding cylinder 10 are arranged in corresponding upper and lower layers on the device frame. The feeding cylinder 10 located on the upper layer is connected to the upper part of the positioning push plate through a connecting plate. The telescopic end of the tension cylinder 11 located on the lower layer is equipped with a tension shaft 14. The lower part of the positioning push plate is provided with a groove that matches the tension shaft 14. The groove does not affect the forward and backward movement of the tension shaft 14.

[0044] In one embodiment, the feed screw is mounted on the bottom side of the device frame, the servo motor drives the feed screw to rotate, the tool holder 16 is mounted on the top side of the device frame, and the bottom of the tool holder 16 is fixedly connected to the screw nut on the feed screw through a fixing seat.

[0045] The working process of the dual-station inner chamfering device for rubber rollers of the present invention is as follows:

[0046] 1. When the feeding lifting cylinder 1 is in the lifting state, the second rubber roller dropping control cylinder 4 is pressed down, and the first rubber roller dropping control cylinder 3 is released, a rubber roller will fall into the V-shaped block groove 5. The feeding screw 2 drives the V-shaped block groove 5 to move forward to the second material groove to the discharge port; then the first rubber roller dropping control cylinder 3 is pressed down, and the second rubber roller dropping control cylinder 4 is released, and the rubber roller will roll to the first rubber roller dropping control cylinder 3 and be blocked. The above actions are repeated to feed material into the V-shaped block groove 5.

[0047] 2. After the two V-shaped slots 5 are filled with material, the photoelectric sensor signal is transmitted, and the feeding screw 2 starts to move to send the V-shaped slots 5 to the chamfering station.

[0048] 3. Positioning cylinder 6 is in the ejection state, and material ejection cylinder 7 is in the air-off state; feeding cylinder 10 drives feeding plate to push rubber roller from V-shaped block groove 5 into tension sleeve 13 and is blocked by positioning plate 8.

[0049] 4. At this time, the feeding cylinder 10 has not yet retracted. The tensioning cylinder 11 drives the tensioning shaft 14 to push into the tensioning sleeve 13. At the same time, the V-shaped block groove 5 begins to descend and is driven by the feeding screw 2 to retract to the discharge port to start feeding into the V-shaped block groove 5. At this time, the positioning cylinder 6 retracts and the ejection cylinder 7 starts to ventilate. The ejection cylinder 7 drives the positioning plate 8 to retract (the positioning plate 8 is connected to the ejection cylinder 7, and the positioning cylinder 6 is not connected to the positioning plate 8). At the same time, the feeding cylinder 10 drives the feeding push plate 9 to retract to the initial position.

[0050] 5. The tensioning sleeve 13 is driven to rotate by the DC brushless motor 17, which in turn drives the tensioning shaft 14 inserted into the tensioning sleeve 13 to rotate together.

[0051] 6. At this time, the active wheel side feed servo motor 21 and the driven wheel side feed servo motor 19 simultaneously drive the active wheel side feed screw 20 and the driven wheel side feed screw 18 to move and drive the two side tool holders 16 to move towards the rubber roller, so that the inner holes on both sides of the rubber roller are chamfered.

[0052] 7. After the tool holder 16 moves to the specified distance, it retracts; at the same time, the tensioning cylinder 11 drives the tensioning shaft 14 to retract to the initial position. At this time, the unloading cylinder 7 extends forward, driving the positioning plate 8 to remove the prepared rubber roller from the tensioning sleeve 13; this process is repeated to perform the next loading action.

[0053] It should be noted that, for those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description.

Furthermore, those skilled in the art will recognize that, based on the ideas of this invention, there will be changes in the specific implementation methods and application scope.
