Description

Technical Field

[0001] The utility model relates to the technical field of grinding machines, in particular to a feeding mechanism for a small rubber roller grinding machine. Background Art

[0002] In the process of producing small rubber rollers, they need to be processed, such as grinding. Due to the small size of small rubber rollers, if manual feeding, grinding and discharging are relied on, the efficiency is low, so special grinding machines are required.

[0003] However, the current grinding machines have the following problems: (1) After the rubber roller is ground, debris is likely to adhere to its surface. If not cleaned in time, it will cause wear to the surface of the rubber roller; (2) After the rubber roller is ground, it is necessary to drive the clamping jaw through a displacement mechanism or drive the clamping jaw to rotate through a rotating mechanism, so that the clamping jaw and the rubber roller on it are far away from the grinding area, and at the same time, the rubber roller is placed in the discharging area. However, the interval time is relatively long during the movement or rotation of the clamping jaw, reducing the discharging efficiency. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a feeding mechanism for a small rubber roller grinding machine to solve the problems mentioned in the above background art.

[0005] To solve the above technical problems, the utility model provides the following technical solutions:

[0006] A feeding mechanism for a small rubber roller grinding machine includes a support frame. A bearing plate is installed on the support frame. A clamping mechanism capable of moving back and forth and left and right is installed on the bearing plate. One side of the support frame is connected with a support arm, and the other side is connected with a hopper. The clamping mechanism is located between the support arm and the hopper. A jet pipe is rotatably connected to the support arm. One end of the jet pipe close to the hopper is connected with a sleeve. A brush is arranged on the inner wall of the sleeve. The clamping end of the clamping mechanism is aligned with the sleeve. A housing is arranged on the side of the support arm far away from the hopper. A driving mechanism for driving the jet pipe to rotate is arranged in the housing. The outer end of the jet pipe is connected with a hose through a rotary joint. The hose is connected with an external air supply device. An opening is arranged on the side of the hopper facing the clamping mechanism. The clamping end of the clamping mechanism can move into the hopper.

[0007] Preferably, the clamping mechanism includes a first cylinder installed on the bearing plate, a first mounting plate connected to the telescopic end of the first cylinder, a second cylinder connected to the first mounting plate, a second mounting plate connected to the telescopic end of the second cylinder, and a finger cylinder connected to the second mounting plate. The second cylinder is perpendicular to the first cylinder. When the first cylinder works, the finger cylinder can move back and forth. When the second cylinder works, the finger cylinder can move left and right.

[0008] In the above technical solution, the rubber roller is grasped by a finger cylinder, the finger cylinder is controlled to move back and forth by a first cylinder, and the finger cylinder is controlled to move left and right by a second cylinder, so that the rubber roller is inserted into the sleeve or the rubber roller enters the hopper.

[0009] Preferably, the driving mechanism includes a motor installed on the support arm, a transmission shaft connected to the motor through a coupling, a main gear connected to the transmission shaft, and a sub-gear fixedly connected to the air injection pipe, and the main gear meshes with the sub-gear.

[0010] In the above technical solution, when the motor is started, the transmission shaft is driven to rotate. Through the cooperation of the main gear and the sub-gear, the air injection pipe is driven to rotate, so that the sleeve can be driven to rotate.

[0011] Preferably, an annular groove is provided in the rotary joint. The outer end of the air injection pipe is connected with an annular ring, and the annular ring is rotatably arranged in the annular groove. An L-shaped rod is connected to the outside of the housing, and the lower end of the L-shaped rod is fixedly connected to the top surface of the rotary joint; an annular sealing gasket is provided in the annular groove.

[0012] In the above technical solution, since the L-shaped rod is connected to the rotary joint, when the air injection pipe is driven to rotate, the rotary joint remains fixed, and the air injection pipe rotates in the annular groove through the annular ring. Through the action of the sealing gasket, the annular ring can always maintain a seal with the rotary joint when rotating, preventing gas leakage.

[0013] Preferably, a downwardly inclined blanking channel is connected to the rear side of the hopper, and the blanking channel is connected to the support frame by bolts.

[0014] In the above technical solution, the cleaned rubber roller enters from the hopper and is finally conveyed to the next link through the blanking channel.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] (1) After the rubber roller grinding is completed, the clamping mechanism drives the rubber roller to move towards the sleeve direction, and the rubber roller enters the sleeve. The driving mechanism drives the air injection pipe to rotate, thereby driving the sleeve to rotate, so as to clean the surface of the sleeve through the brush, and then the air supply device supplies air to the air injection pipe, thereby blowing air on the rubber roller to blow the debris off the rubber roller.

[0017] (2) After the rubber roller cleaning is completed, the clamping mechanism drives the rubber roller into the hopper and releases the rubber roller, so that the rubber roller is conveyed to the next link through the hopper, improving the convenience of blanking.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

The air supply device can be a blower or an air compressor.

[0027] As Figure 4As shown in the figure, the clamping mechanism 3 includes a first cylinder 301 installed on the bearing plate, a first mounting plate 302 connected to the telescopic end of the first cylinder, a second cylinder 303 connected to the first mounting plate, a second mounting plate 304 connected to the telescopic end of the second cylinder, and a finger cylinder 305 connected to the second mounting plate. The second cylinder 303 is perpendicular to the first cylinder 301. When the first cylinder 301 works, it can make the finger cylinder 305 move back and forth, and when the second cylinder 303 works, it can make the finger cylinder 305 move left and right. After the rubber roller is polished, the first cylinder 301 extends, driving the finger cylinder 305 to move towards the polishing area, and the finger cylinder 305 grabs the rubber roller 19. Then the second cylinder 303 contracts to align the rubber roller with the sleeve 7, and then the second cylinder 303 controls the finger cylinder 305 to move towards the sleeve 7 to insert the rubber roller into the sleeve 7. An opening is provided on one side of the hopper 5 facing the clamping mechanism. When the second cylinder 303 extends, it can drive the finger cylinder 305 to move from the opening into the hopper 5, thereby putting the cleaned rubber roller into the hopper 5.

[0028] As Figure 2 shown in the figure, the driving mechanism includes a motor 11 installed on the support arm, a transmission shaft connected to the motor through a coupling, a main gear 12 connected to the transmission shaft, and a sub-gear 13 fixedly connected to the air injection pipe.

While the sleeve is rotating, the air supply device supplies air to the air injection pipe 6 to blow air on the rubber roller to blow the debris off the rubber roller. Moreover, when the rubber roller leaves the sleeve 7, blowing air through the air injection pipe 6 will also clean the inside of the sleeve 7 and blow the debris out of the sleeve 7 to prevent the debris from sticking to the brush.

Through the action of the sealing gasket 17, the annular ring 15 can always maintain a seal with the rotary joint 9 when rotating to prevent gas leakage.
