Description

Technical Field

[0001] The utility model relates to the field of pellet counting machines, in particular to a pellet counting machine blanking device. Background Art

[0002] In the prior art, automatic tablet counting machines have been able to achieve streamlined operations without manual intervention throughout the entire process. For example, the utility model patent with authorization announcement number CN203544506U discloses a tablet counting machine that can automatically count and bottle tablets, greatly improving production efficiency. In addition, in order to prevent the granules or tablets from clogging the hopper nozzle and affecting the counting accuracy, its matching hopper mechanism is provided with a cylinder vibration device as shown in the utility model patent with authorization announcement number CN203624262U. The hopper can move up and down under the drive of the cylinder vibration device, so that the material in the nozzle can be discharged, avoiding nozzle blockage and ensuring accurate counting. Therefore, the above-mentioned products have been well applied in the market.

[0003] However, the applicant found in actual use that the existing cylinder vibration type unloading hopper controls the up and down vibration of the hopper by the extension and contraction of the cylinder. This structure requires the cylinder to be repeatedly extended and contracted, resulting in large cylinder wear and a short service life. In addition, the extension and contraction cycle of the cylinder is long, resulting in low unloading efficiency and high noise. Utility Model Content

[0009] Preferably, two groups of semicircular assembly bars are provided on the side wall of the hopper and are arranged one above the other, and a groove for assembling with the fork body is formed between the two groups of semicircular assembly bars.

[0010] Compared with the prior art, the pellet counting machine feeding device disclosed in the present invention has the following beneficial effects:

[0011] The electromagnet is used in conjunction with the adsorption block to achieve rapid switching between adsorption and release. The bending of the elastic plate can realize the up and down vibration of the hopper. The overall efficiency is high and the noise is low. At the same time, compared with the shaking cylinder, the service life is greatly improved.

[0017] The following embodiments of the technical solution of the present invention are described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention.

[0018] The utility model discloses a feeding device for a counting machine, the structure of which is as follows: Figures 1-3 As shown, it includes a mounting base 1, an electromagnet 2, a gate-shaped spring plate 3, an adsorption block 4, a fork frame 5, and a hopper 6. The electromagnet is fixed to the mounting base, the gate-shaped spring plate covers the outside of the electromagnet, and both ends of the gate-shaped spring plate are fixed to the mounting base. The adsorption block is fixed to the gate-shaped spring plate and is located directly above the electromagnet. One end of the fork frame is fixed between the adsorption block and the gate-shaped spring plate, and the other end is equipped with a hopper.

[0019] During use, the electromagnet is powered on and off. When the electromagnet is powered on, it has adsorption force to absorb the adsorption block above. Since the door-shaped spring plate has a certain elasticity, it can bend downward with the adsorption block. When the electromagnet is powered off, the adsorption force disappears, and the adsorption block moves upward and resets under the elastic force of the door-shaped spring plate. This up and down action causes the hopper to shake and discharge materials. The electromagnet has low working noise and long service life.

[0020] Specifically, both sides of the mounting base are bent vertically upward to form mounting strips 11, and the electromagnet is fixed in the middle of the mounting base. The mounting strips on both sides can fix the door-shaped spring plate.

[0021] The door-shaped spring plate consists of a top spring plate 31 and two side spring plates 32, wherein the top spring plate is used to assemble the adsorption block and is the main part of the elastic deformation, the side spring plates provide support and auxiliary elastic deformation, the top spring plate and the side spring plates are fixed by the connecting block 33 with bolts, and the bottom of the side spring plate is assembled on the mounting bars on both sides of the mounting base with bolts.

[0022] The adsorption block is made of metal and can be adsorbed by the electromagnet after the electromagnet is energized. A plurality of bolts 41 are integrally formed on the surface of the adsorption block, and these bolts pass through the fork frame and the top spring plate and cooperate with nuts to achieve fixed assembly.

[0023] The fork frame includes a frame body (located inside the assembly, not marked), a semicircular fork body 51 located at one end of the frame body, and a counterweight block 52 located at the other end of the frame body. The frame body is provided with a penetrating mounting hole corresponding to the bolt position on the surface of the adsorption block, which is convenient for installation above the adsorption block. The semicircular fork body is used to assemble the hopper. Since the hopper has a certain weight, the counterweight block is provided to maintain balance after the fork frame is assembled, so as to avoid tilting due to excessive weight on one side of the hopper, which affects the subsequent adsorption effect.

[0024] Two groups of semicircular assembly strips 61 are arranged up and down on the side wall of the hopper, and a groove 62 for assembling with the fork body is formed between the two groups of semicircular assembly strips. During assembly, the fork body is embedded in the groove, and the two ends cooperate with the limit blocks 7 and bolts to achieve assembly. The end of the fork body is provided with a threaded hole 53 for the bolt to be screwed in. The two groups of assembly strips arranged up and down can realize the up and down shaking of the hopper inward, and the use of the limit blocks can prevent the hopper from separating from the fork body during the shaking process.

[0025] The utility model discloses a feeding device for a pellet counting machine. After the product is poured into the hopper, the electromagnet is powered on and off to realize up and down shaking control. The whole device is not only more efficient and has a long service life, but also has low noise.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention.
