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 Technique

[0002] In the process of producing small rubber rollers, processing such as grinding is required. Since the rubber rollers are small in size, if the rubber rollers are manually placed at the grinding position, the work efficiency will be low. Therefore, a special feeding device is needed. However, the current small rubber roller feeding devices have the following problems: (1) Some directly grab the rubber rollers one by one with clamping jaws. Since the rubber rollers are small in size, the clamping jaws may miss during the grabbing process, or may grab multiple rubber rollers at a time, which is inconvenient for subsequent processing; (2) Some convey the rubber rollers to the clamping jaws one by one through a conveying channel, but the inclination of the conveying channel cannot be adjusted, and the rubber rollers are easily blocked and cannot roll down, affecting subsequent processing. Content of the Utility Model

[0003] 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 technique.

[0004] To solve the above technical problems, the utility model provides the following technical solutions:

Specific embodiments

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1

[0021] Please refer to Figure 1-2 , a feeding mechanism for a small rubber roller grinding machine, including a bottom plate 1, a support plate 2 fixed at one end of the bottom plate 1, a rotating shaft 3 rotatably connected to the support plate 2, a feeding channel 4 connected to the outer end of the rotating shaft 3, an arc-shaped hole 5 centered on the rotating shaft provided on the support plate 2, a sliding rod 6 slidably connected in the arc-shaped hole 5, the outer end of the sliding rod 6 being connected to the feeding channel 4, a wall panel 7 connected to the support plate 2, a mounting plate 8 connected to the wall panel 7, a first cylinder 9 connected to the mounting plate 8, a material receiving mechanism 10 connected to the first cylinder 9, the material receiving mechanism 10 receiving the rubber roller sliding out of the feeding channel 4, and a driving device for driving the feeding channel 4 to rotate along the rotating shaft 3 provided on the bottom plate 1. Specifically, the driving device is a second cylinder 12 hinged to the bottom plate, and the telescopic end of the second cylinder 12 is hinged to the bottom of the feeding channel 4. The rubber roller is conveyed downward through the feeding channel 4, so that the rubber roller falls onto the material receiving mechanism 10, and the material receiving mechanism 10 catches the rubber roller, without having to grasp the rubber roller one by one, so that it will not miss or grasp multiple rubber rollers at a time. When the feeding channel 4 is blocked, the second cylinder 12 extends to drive the feeding channel 4 to rotate around the rotating shaft 3 (as Figure 4 shown), increasing the inclination of the feeding channel 4, so that the rubber roller slides downward under the action of gravity to prevent blockage.

[0022] The material receiving mechanism 10 includes a material head main body 101 connected to a cylinder. A U-shaped groove 102 is provided on the material head main body 101. Hinge plates 103 are connected to both sides of the U-shaped groove on the material head main body 101. An L-shaped bearing plate 104 is hinged on the two hinge plates 103. The lower end of the bearing plate 104 is located below the material head main body 101, and the bearing plate is docked with the lower part of the material head main body. A notch 105 matching the rubber roller is provided on the bottom surface of the material head main body 101 facing the feeding channel side. The rubber roller is pressed on the bearing plate 104 through the notch 105. A limiting rod 106 is connected to the upper part of the material head main body 101. A strip-shaped hole 107 is provided in the upper part of the bearing plate 104. The limiting rod 106 passes through the strip-shaped hole 107, and a limiting plate 108 is connected to the passing end. A spring 109 is sleeved on the limiting rod 106. One end of the spring 109 is connected to the material head main body 101, and the other end is connected to the bearing plate 104. A stop block 110 extending downward is connected to one end of the wall plate 7 far from the mounting plate. The lower part of the side of the stop block 110 facing the material head main body is an inclined surface. The upper end of the bearing plate 104 abuts against the inclined surface. The bearing plate 104 is squeezed by the inclined surface of the stop block 110, so that the spring 109 is in a compressed state, so that the bearing plate 104 is separated from the material head main body 101. It should be noted that when the bearing plate 104 leaves the stop block 110, the bearing plate 104 rotates to the side away from the material head main body 101 under the action of the spring 109 until the bottom of the bearing plate 104 contacts the bottom surface of the material head main body 101. At this time, the rubber roller is pressed into the notch 105 of the material head main body 101 by the upward force at the lower end of the bearing plate 104 to prevent the rubber roller from falling. At this time, the upper end of the bearing plate 104 is still directly below the inclined surface of the stop block 110, so that after the bearing plate 104 rises, the inclined surface of the stop block 110 can squeeze the bearing plate 104.

[0023] In this embodiment, as Figure 3 shown, hinge shafts are fixedly connected to the two hinge plates 103. A rotating part 111 is provided on the inner side of the bearing plate 104. The rotating part 111 is movably arranged in the U-shaped groove 102. The rotating part 111 is rotatably connected to the hinge shaft. The rotating part 111 is movably arranged in the U-shaped groove 102. Through the cooperation of the rotating part and the U-shaped groove, the bearing plate 104 can also be limited to a certain extent to prevent it from rotating excessively.

[0024] In this embodiment, as Figure 2 shown, a nut 11 is threadedly connected to the end of the sliding rod 6 far from the feeding channel. Rotating the nut 11 can make it tightly press on the support plate 2. When the angle of the feeding channel 4 is adjusted, tightening the nut 11 can keep the feeding channel 4 stable.

[0025] The working principle of this embodiment is as follows: When the first cylinder 9 is in the contracted state, the upper part of the bearing plate 104 contacts the inclined surface of the stopper 110. Through the extrusion of the stopper 110, the lower part of the bearing plate 104 opens. After the rubber roller 13 drops from the feeding channel 4 onto the bearing plate 104, it enters the notch 105 of the nozzle body 101. Then the first cylinder 9 extends, driving the nozzle body 101 to descend, so that the upper part of the bearing plate 104 separates from the stopper 110. At this time, under the restoring force of the spring 109, the upper part of the bearing plate 104 rotates away from the nozzle body 101, and the lower part of the bearing plate 104 rotates towards the nozzle body 101. Thus, the rubber roller is tightly pressed in the notch 105 by the lower part of the bearing plate 104, realizing the clamping of the rubber roller to send the rubber roller to the processing location.

[0026] Embodiment 2

[0027] The difference between this embodiment and Embodiment 1 is that positioning holes are provided on the bottom plate 1. Through the cooperation of bolts and positioning holes, the bottom plate can be fixed on the grinding machine.

Without further limitation, an element defined by the phrase "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or device including the element.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
