Description

Technical Field

[0001] The utility model belongs to the technical field of the installation of rubber sleeves for driving rollers, and in particular relates to a device for reinstalling rubber sleeves for driving rollers. Background Art

[0002] A driving roller is a component used in a conveyor, mainly for transmitting power and driving the conveyor belt to move. In order to increase the friction force, a rubber sleeve is usually sleeved outside the driving roller. After long-term use, the rubber sleeve will age and wear, so it needs to be replaced in time. At present, the replacement of the rubber sleeve is usually completed manually. Because the friction force between the inner side of the rubber sleeve and the driving roller is large, it requires the cooperation of multiple workers to completely sleeve the rubber sleeve on the driving roller, which is time-consuming and laborious, and is prone to damage the rubber sleeve. Therefore, it is necessary to make improvements. Content of the Utility Model

[0003] In order to solve the above-mentioned defects of the prior art, the present application provides a device for reinstalling a rubber sleeve for a driving roller, which can quickly push the driving roller into the rubber sleeve and improve the installation efficiency.

[0004] In order to achieve the above purpose, the utility model adopts the following technologies:

[0006] An adsorption ring, which has an annular cavity inside, and a plurality of adsorption holes are arranged in a circumferential array on the inner side of the adsorption ring. The adsorption ring is fixed on a support frame, and the annular cavity is communicated with the suction end of a suction mechanism;

[0007] An air inlet connector, which is arranged at one end of the adsorption ring at intervals coaxially;

[0008] A linear mechanism, which is arranged at the other end of the adsorption ring and is used to push the driving roller along the axial direction of the adsorption ring towards the air inlet connector.

[0009] Further, the linear mechanism includes a driving motor, a lead screw, a guide rod. The lead screw is rotatably arranged between a pair of inverted U-shaped frames, and the pair of inverted U-shaped frames are fixed above the support frame. The lead screw is threadedly connected with a push plate, and the guide rod is penetrated through the push plate. The two ends of the guide rod are respectively connected with the pair of inverted U-shaped frames, and the output shaft of the driving motor is connected with the lead screw.

[0010] Further, a limiting ring with the same axial direction as the adsorption ring is arranged on the side of the push plate facing the adsorption ring, and the inner diameter of the limiting ring matches the diameter of the driving roller.

[0011] Further, the bottom of the adsorption ring is connected with the support frame, and the top of the adsorption ring is connected with one of the inverted U-shaped frames.

[0012] Further, the air inlet connector is slidably arranged in a connecting ring, and the connecting ring is fixed on the support frame and has the same axial direction as the adsorption ring.

[0013] The beneficial effects of the present utility model are as follows:

[0014] The device can inject air into the rubber sleeve to make the rubber sleeve expand, which can reduce the contact area between the rubber sleeve and the driving roller during installation, thereby reducing the friction between the rubber sleeve and the driving roller during installation.

Detailed Embodiments

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will describe the embodiments of the present utility model in detail with reference to the drawings. However, the embodiments described herein are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] The embodiment of the present application provides a device for reinstalling the rubber sleeve of a driving roller. As Figures 1-3 shown, it includes an adsorption ring - 1, an air inlet connector 8, a linear mechanism, etc.

[0021] Specifically, the adsorption ring - 1 has an annular cavity inside. A plurality of adsorption holes - 101 are arranged in a circumferential array on the inner side of the adsorption ring - 1. The adsorption ring - 1 is fixed on a support frame - 2, and the annular cavity is communicated with the air suction end of an air suction mechanism - 3; the air inlet connector 8 is arranged at one end of the adsorption ring - 1 at the same axis at intervals; the linear mechanism is arranged at the other end of the adsorption ring - 1 and is used to push the driving roller - 4 along the axial direction of the adsorption ring - 1 towards the air inlet connector 8.

[0022] In actual use, one end of the rubber sleeve is placed into the adsorption ring - 1, and then the air suction mechanism - 3 is turned on. The rubber sleeve is sucked up through the adsorption holes - 101, and a negative pressure is generated in the annular cavity of the adsorption ring - 1 to fix one end of the rubber sleeve. Then, the air inlet connector 8 is inserted into the other end of the rubber sleeve, and the air inlet of the air inlet connector 8 is connected to an air inflation device. At the same time, the air inflation device is turned on, and air can be injected into the rubber sleeve to make the rubber sleeve expand. At this time, one end of the transmission roller - 4 is pushed into one end of the rubber sleeve. Because the rubber sleeve is in an expanded state, the contact area with the transmission roller - 4 can be reduced, thereby reducing the friction force with the transmission roller - 4 during the pushing process. Finally, controlling the linear mechanism to push the transmission roller - 4 towards the air inlet connector 8 can quickly push the transmission roller - 4 into the rubber sleeve.

[0023] In one embodiment, referring to Figure 1 , Figure 2 , the linear mechanism includes a driving motor - 5, a lead screw - 501, a guide rod - 502. The lead screw - 501 is rotatably arranged between a pair of inverted U - shaped frames - 6. The pair of inverted U - shaped frames - 6 are fixed above the support frame - 2. The lead screw - 501 is threadedly connected to a push plate - 7. The guide rod - 502 is passed through the push plate - 7, and both ends of the guide rod - 502 are connected to the pair of inverted U - shaped frames - 6 respectively. The output shaft of the driving motor - 5 is connected to the lead screw - 501. By controlling the driving motor - 5 to drive the lead screw - 501 to rotate, the push plate - 7 can be driven to move axially along the adsorption ring - 1, and the transmission roller - 4 can be automatically pushed into the rubber sleeve. Specifically, referring to Figure 2 , a limiting ring - 701 with the same axis as the adsorption ring - 1 is arranged on the side of the push plate - 7 facing the adsorption ring - 1. The inner diameter of the limiting ring - 701 matches the diameter of the transmission roller - 4. During use, one end of the transmission roller - 4 is placed into the limiting ring - 701, and the other end of the transmission roller - 4 is placed into the adsorption ring - 1. By pushing the transmission roller - 4 in this way, the transmission roller - 4 can be prevented from tilting, and the stability of the transmission roller - 4 during movement can be improved. More specifically, the bottom of the adsorption ring - 1 is connected to the support frame - 2, and the top of the adsorption ring - 1 is connected to one of the inverted U - shaped frames - 6 to improve the stability of the adsorption ring - 1.

[0024] Specifically, the air inlet connector 8 is slidably arranged in a connection ring. The connection ring is fixed on the support frame - 2, and the connection ring has the same axis as the adsorption ring - 1. When the transmission shaft is pushed by the linear mechanism to abut against the air inlet connector 8, it can continue to move forward until it completely enters the rubber sleeve.

[0025] The above are only some embodiments listed in this application and do not limit this application.
