Description

Technical Field

[0001] This utility model relates to a feeding device, and more specifically, to a rotary feeding device for the production of plastic products. Background Technology

[0002] For cylindrical, sheet-like, and ring-shaped materials, a rotary feeding device can be used to feed them. The material is inserted into the feeding rod, and then the feeding rod containing the material is rotated to the robotic arm. The robotic arm then removes the material from the feeding rod by gripping or adsorbing it.

[0003] However, existing rotary feeding devices have the following drawbacks: as the material on some of the feeding rods decreases, the center of gravity of the rotating feeding disc is easily shifted, affecting the accuracy of material conveying and causing the robot arm to be misaligned with the material.

[0004] Therefore, it is necessary to propose a technical means to solve the above-mentioned defects. Utility Model Content

Multiple materials can be stacked on each insert rod from bottom to top. The frame also includes balancing mechanisms to prevent the rotary feeding disc from tilting. These balancing mechanisms are evenly distributed below the rotary feeding disc. Each balancing mechanism includes a support base and rollers that contact the rotary feeding disc. The rollers are rotatably connected to the top of the support base via a rotating shaft. The support base is fixedly connected to the frame.

The power end of the drive cylinder is fixedly connected to a connecting plate. The two push rods are respectively vertically arranged on both sides of the connecting plate, and the top of the push rods extends to the bottom of the rotary feeding plate; the rotary feeding plate has through holes on both sides near the insert rod for the push rods to extend out, and the through holes are located below the material; the top of the push rods can extend or retract through the through holes to the upper surface or below the rotary feeding plate.

[0008] Preferably, the height of the push rod extending from the upper surface of the rotating feeding disc is greater than the height of the insert rod.

[0010] Preferably, the frame is equipped with a sensor for sensing whether material is fitted onto the insert rod.

[0011] Compared with the prior art, the novel advantages of this utility model are:

[0012] The feeding device of this application, by setting a balancing mechanism at the bottom of the rotary feeding disc, not only prevents the center of gravity of the rotary feeding disc from shifting due to uneven material weight, but also provides support for the rotary feeding disc.

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

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a rotary feeding device for producing plastic products includes a frame 1 and a rotary feeding disc 2 rotatably connected to the top of the frame 1. The edge of the feeding disc 2 is circumferentially arranged with multiple vertically arranged insert rods 3, evenly spaced apart. Multiple materials 31 can be stacked on each insert rod from bottom to top. The frame 1 is also equipped with multiple balancing mechanisms 6 to prevent the rotary feeding disc 2 from tilting. These balancing mechanisms 6 are evenly distributed below the rotary feeding disc 2. Each balancing mechanism 6 includes a support base 61 and rollers 62 that contact the rotary feeding disc. The rollers 62 are rotatably connected to the top of the support base 61 via a rotating shaft. The support base 61 is fixedly connected to the frame 1.

[0020] Furthermore, the frame is also equipped with a lifting and feeding mechanism 4 that pushes a piece of material 31 located at the bottom of the insert rod 3 to move upward. The lifting and feeding mechanism 4 includes a mounting base 41 fixedly connected to one side of the frame 1, a drive cylinder 42 fixedly connected to the mounting base 41, and two push rods 44. The power end of the drive cylinder 42 is fixedly connected to a connecting plate 43. The two push rods 44 are respectively vertically arranged on both sides of the connecting plate 43, and the top of the push rods 44 extends to the bottom of the rotary feeding plate 2. The rotary feeding plate 2 has through holes 21 on both sides near the insert rod 3 for the push rods 44 to extend out. The top of the push rods 44 can extend or retract through the through holes 21 to the upper or lower surface of the rotary feeding plate 2.

[0021] Furthermore, the height of the push rod 44 extending from the upper surface of the rotating feed plate 2 is greater than the height of the insert rod 3.

[0022] Furthermore, such as Figure 4 As shown, the frame 1 is also equipped with a transmission mechanism 7 for driving the rotating feed disc 2 to rotate. The transmission mechanism 7 includes a motor 71, a synchronous belt 74, a main drive wheel 72 and a secondary drive wheel 73. The motor 71 is fixedly connected to the frame 1, and the main drive wheel 72 is fixedly connected to the power end of the motor 71. The secondary drive wheel 73 is fixedly connected to the bottom center of the rotating feed disc 2. The synchronous belt 74 is tensioned on the main drive wheel 72 and the secondary drive wheel 73.

[0023] Furthermore, the frame 1 is equipped with a sensor 5 for sensing whether material 31 is fitted on the insert rod 3.

[0024] In summary, the feeding device of this application, by setting a balancing mechanism at the bottom of the rotating feeding disc 2, not only prevents the center of gravity of the rotating feeding disc 2 from shifting due to uneven material weight, but also provides support for the rotating feeding disc 2. Moreover, the rollers on the balancing mechanism 6 are in contact with the rotating feeding disc 2, and when the rotating feeding disc 2 rotates, the rollers also rotate, without causing resistance to the rotation of the rotating feeding disc 2, resulting in a simple and reasonable structure.

[0025] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
