Description

Technical Field

[0001] This utility model relates to the field of grain counting machine technology, specifically to the installation structure of the grain counting machine's feed hopper. Background Technology

[0002] A tablet counter is a machine used in industries such as pharmaceuticals, hospitals, and food to count capsules, tablets, granules, and other medicines or food products. The feeding mechanism of the counter has a hopper at the bottom, designed to fit around the bottle opening and fill the bottle with granules. The hopper's outlet must match the bottle opening (if the outlet size is smaller than the bottle opening, granules may get stuck; if it's larger, some granules may not be able to enter the bottle). Therefore, when the bottle opening size changes, the hopper size needs to be changed. Currently, the hopper is connected to one end of a connecting plate, and the other end is bolted to a lifting block equipped with a cylinder to raise and lower the hopper. Changing the hopper requires removing and installing bolts, which is time-consuming and labor-intensive. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this utility model provides an installation structure for the feed hopper of a grain counting machine, which solves the problem that replacing the feed hopper by disassembling and assembling bolts is time-consuming and labor-intensive.

[0004] The technical solution adopted in this utility model is as follows:

[0005] The mounting structure of the hopper of the counting machine includes a connecting plate, one end of which is equipped with a hopper, and the other end is connected to a lifting block. The lifting block is equipped with a cylinder. The structure also includes:

[0006] A through slot is provided on the lifting block;

[0007] A first protrusion is provided on the connecting plate and is used to cooperate with the through groove. The first protrusion can move back and forth within the through groove.

[0008] Mounting hole number one is located at the rear end of the through slot and is connected to the through slot;

[0009] A rotating shaft is used to mate with mounting hole number one, with one end of the rotating shaft located outside mounting hole number one.

[0010] A notch is provided on the rotating shaft, and the notch is located at the connection between the through groove and the first mounting hole;

[0011] The grip is located at the end of the shaft that is outside the first mounting hole;

[0012] A flexible reset element is located at the other end of the rotating shaft;

[0013] A limit block is located on the side of the lifting block and is used to cooperate with the hand grip.

[0014] One side of the first protrusion is provided with a groove for engaging with the rotating shaft.

[0015] The front end of the top of the first protrusion is provided with a second protrusion. The length of the second protrusion and the first protrusion are equal to the length of the through groove. When the first protrusion is engaged with the through groove, the bottom surface of the second protrusion and the top surface of the lifting block are on the same plane.

[0016] The limiting block is provided with a first limiting groove for cooperating with the hand grip.

[0017] The side of the lifting block is provided with a second limiting groove for cooperating with the limiting block, and the limiting block is connected to the lifting block by bolts.

[0018] The lifting block has a second mounting hole on the side away from the hand grip for concentric alignment with the first mounting hole. The diameter of the second mounting hole is larger than that of the first mounting hole. One end of the rotating shaft has a retaining ring located in the second mounting hole. The elastic reset element is a spring, with one end connected to the retaining ring and the other end connected to the second mounting hole.

[0019] The hopper is provided with a positioning groove on the side near the lifting block, and the connecting plate is provided with a positioning post for cooperating with the positioning groove.

[0020] It also includes a mounting plate for mounting the cylinder, the mounting plate having a guide rod for cooperating with the lifting block, and buffer pads at both ends of the guide rod.

[0021] The beneficial effects of this utility model are:

[0022] When the hopper needs to be installed, hold the handle and rotate the shaft. At the same time, the elastic reset component undergoes elastic deformation and generates torsional force. When the shaft rotates to the slot corresponding to its notch, insert the first protrusion into the slot, then release the handle. The elastic reset component returns the shaft to its original position, and the shaft surface contacts and holds the first protrusion, thus installing the hopper on the lifting block. When disassembly is required, simply align the notch with the slot. This structure ensures that the hopper is easy to install and remove, and has high efficiency. Attached Figure Description

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0033] In the embodiments, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the installation structure of the pellet counting machine's feed hopper includes a connecting plate 1, with a feed hopper 3 installed at one end of the connecting plate 1 and a lifting block 4 connected to the other end. The lifting block 4 is equipped with a cylinder 5, and also includes:

[0034] The through groove 6 is set on the lifting block 4;

[0035] The first protrusion 7 is disposed on the connecting plate 1 and is used to cooperate with the through groove 6. The first protrusion 7 can move back and forth within the through groove 6.

[0036] Mounting hole 8 is located at the rear end of through groove 6 and is connected to through groove 6;

[0037] A rotating shaft 9 is used to mate with a first mounting hole 8, with one end of the rotating shaft 9 located outside the first mounting hole 8;

[0038] Notch 10 is provided on the rotating shaft 9, and the notch 10 is located at the connection between the through groove 6 and the first mounting hole 8;

[0039] The grip 11 is located at one end of the rotating shaft 9, outside the first mounting hole 8;

[0040] The elastic reset element 12 is disposed at the other end of the rotating shaft 9;

[0041] The limiting block 13 is disposed on the side of the lifting block 4 and is used to cooperate with the hand grip 11.

[0042] When the feeding hopper 3 needs to be installed, hold the handle 11 and rotate the shaft 9. At the same time, the elastic reset member 12 undergoes elastic deformation and generates torsional force. When the shaft 9 rotates to the point where its notch 10 corresponds to the through groove 6, insert the first protrusion 7 into the through groove 6, and then release the handle 11. The elastic reset member 12 allows the shaft 9 to return to its original position. The surface of the shaft 9 contacts and holds the first protrusion 7, thus installing the feeding hopper 3 on the lifting block 4. When disassembly is required, simply align the notch 10 with the through groove 6. This structure ensures that the feeding hopper 3 is easy to assemble and disassemble, and has high efficiency.

[0043] In the embodiments, such as Figure 5 As shown, a groove 14 for engaging with the rotating shaft 9 is provided on one side of the first protrusion 7. This increases the contact area between the rotating shaft 9 and the first protrusion 7, thereby better supporting the first protrusion 7 and limiting its vertical movement.

[0044] In the embodiments, such as Figure 2 , Figure 3 , Figure 5 As shown, a second protrusion 15 is provided at the front end of the top of the first protrusion 7. The sum of the lengths of the second protrusion 15 and the first protrusion 7 is equal to the length of the through groove 6. When the first protrusion 7 is engaged with the through groove 6, the bottom surface of the second protrusion 15 is on the same plane as the top surface of the lifting block 4. When the rotating shaft 9 pushes the first protrusion 7 forward and abuts against the first protrusion 7, the bottom surface of the second protrusion 15 contacts the top surface of the lifting block 4. The second protrusion 15 is used to prevent the connecting plate 2 and the hopper 3 from automatically falling down when the notch 10 of the rotating shaft 9 faces the first protrusion 7 during the replacement of the hopper 3.

[0045] In the embodiments, such as Figure 7 As shown, the limiting block 13 is provided with a first limiting groove 16 for cooperating with the grip part 11. The grip part 11 is a rod structure. The grip part 11 is locked in the first limiting groove 16 and will not move easily, ensuring that the rotating shaft 9 can stably hold the first protrusion 7.

[0046] In the embodiments, such as Figure 1 As shown, the side of the lifting block 4 is provided with a second limiting groove 17 for cooperating with the limiting block 13. The limiting block 13 is connected to the lifting block 4 by bolts. The second limiting groove 17 limits the left and right positions of the limiting block 13 to ensure that there is no left and right installation error after the limiting block 13 is fixed, thereby ensuring the matching accuracy between the first limiting groove 16 and the grip part 11.

[0047] In the embodiments, such as Figure 4 As shown, the lifting block 4 has a second mounting hole 18 on the side away from the grip 11, which is concentrically fitted with the first mounting hole 7. The diameter of the second mounting hole 18 is larger than the diameter of the first mounting hole 7. One end of the rotating shaft 9 has a retaining ring 19 located inside the second mounting hole 18. The elastic reset member 12 is a spring, with one end connected to the retaining ring 19 and the other end connected to the second mounting hole 18. Rotating the rotating shaft 9 causes the spring to twist, thereby generating torque, which facilitates the reset of the grip 11. The overall structure is simple and easy to install.

[0048] In the embodiments, such as Figure 1 , Figure 6 , Figure 8 As shown, the hopper 3 has a positioning groove 20 on the side near the lifting block 4, and the connecting plate 1 has a positioning post 21 for cooperating with the positioning groove 20. This positions the hopper 3 to prevent it from rotating on the connecting plate 1.

[0049] In the embodiments, such as Figure 1 As shown, it also includes a mounting plate 22 for mounting the cylinder 5. The mounting plate 22 is provided with a guide rod 23 for cooperating with the lifting block 4. The upper and lower ends of the guide rod 23 are provided with buffer pads 24. These buffer pads provide shock absorption and cushioning for the lifting block 4, ensuring that the descent of the hopper 3 is stably coordinated with the bottle body.

[0050] Obviously, the above embodiments of this utility model are merely illustrative examples and not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
