It includes an adjusting plate and a positioning component. The adjusting plate is movable up and down and is disposed on one side of the receiving hopper body. Its lower end is opposite to the discharge port and can partially block the discharge port to adjust the size of the portion of the discharge port opposite to the first vibrating feeder. The positioning component is disposed between the adjusting plate and the receiving hopper body and is used to position the adjusted adjusting plate. The second adjusting component is opposite to the second vibrating feeder and can adjust the size of the portion of the discharge port opposite to the second vibrating feeder.

[0016] Furthermore, the positioning component includes a positioning block, a sliding block, and a positioning knob. The positioning block is disposed on one side of the receiving hopper body, and the sliding block is movable up and down on the positioning block and connected to the upper end of the adjusting plate.

[0027] The present invention will be further described below through specific embodiments.

[0028] Reference Figures 1 to 5 As shown, a counting machine capable of accurate counting can count medicines in capsule or tablet form. It includes a frame 1, a receiving hopper 2, a first conveying device 3, a second conveying device 4, a feeding mechanism 5, a visual counting device 6, a receiving device 7, and a control device 8. Specifically, this application can also be applied to counting other block-shaped materials.

[0029] The receiving hopper 2, mounted on the frame 1, is used to receive incoming materials. It includes a receiving hopper body 21, a first adjusting component 22, a second adjusting component 23, and a limiting plate 24. The receiving hopper body 21 has a discharge port 211 at its lower end. The first adjusting component 22 is opposite to the first conveying device 3 and can adjust the size of the portion of the discharge port 211 opposite to the first conveying device 3. It includes an adjusting plate 221 and a positioning element 222. The second adjusting component 23 is opposite to the second conveying device 4 and can adjust the size of the portion of the discharge port 211 opposite to the second conveying device 4. The limiting plate 24 is located on one side of the receiving hopper body 21 and has an adjusting hole 241 extending vertically. Specifically, the structure of the second adjusting component 23 is the same as that of the first adjusting component 22, which will not be described further here.

[0030] Positioning component 222 is disposed between adjusting plate 221 and receiving hopper body 21 for positioning the adjusted adjusting plate 221. It includes positioning block 225, sliding block 226 and positioning knob. Positioning block 225 is disposed on one side of receiving hopper body 21. Sliding block 226 is movable on positioning block 225 and connected to the upper end of adjusting plate 221. Positioning knob is disposed between positioning block 225 and sliding block 226 for fixing the adjusted sliding block 226. During assembly, a slotted hole can be provided on sliding block 226 to cooperate with positioning knob to fix the adjusted sliding block 226. This method is commonly used in the mechanical field. The usage of positioning knob will not be further described here.

[0031] The adjusting plate 221 is movable up and down and is located on one side of the receiving hopper body 21. Its lower end can pass through the adjusting hole 241 and be opposite to the discharge port 211. It can partially block the discharge port 211 and thus adjust the size of the part of the discharge port 211 opposite to the first conveying device 3. Specifically, the adjusting plate 221 includes an adjusting section 223 that passes through the adjusting hole 241 and is opposite to the discharge port 211, and a connecting section 224 that is located at the upper end of the adjusting section 223 and connected to the sliding block 226. During operation, the position of the adjusting plate 221 can be adjusted according to the size of the medicine tablet, thereby adjusting the height of the discharge port 211 so that it can meet the conveying count of medicine tablets of the corresponding size.

[0032] The first conveying device 3, mounted on the frame 1, includes a first vibrating feeder 31, a first baffle plate 32, and a first driving member 33, all mounted on the frame 1. The first vibrating feeder 31 conveys incoming material to the receiving device 7. The first baffle plate 32 is rotatably mounted on the frame 1, positioned above the first vibrating feeder 31, and can block further material conveying from the first vibrating feeder 31. The first driving member 33 connects to and drives the first baffle plate 32 to rotate, blocking or releasing material. When it is necessary to stop the conveying of the first vibrating feeder 31, the first driving member 33 drives the first baffle plate 32 to rotate downwards. The lower end of 32 is close to the conveying surface of the first vibrating feeder 31 to block the material from continuing to be conveyed forward. Specifically, the first vibrating feeder 31 is a commonly used device in the field of material conveying. Its specific structure and working principle will not be described in detail here. The first vibrating feeder 31 is used to convey materials. While conveying materials falling from the receiving hopper 2, it can also disperse the materials and prevent the materials from piling up and affecting the subsequent counting. Furthermore, the first driving component 33 can be a cylinder. The first baffle plate 32 is provided with a rotating rod 34 that is rotatably connected to the frame 1. The cylinder is connected to the first baffle plate 32 to drive the rotation of the first baffle plate 32.

[0033] The second conveying device 4 is mounted on the frame 1 and includes a second vibrating feeder 41 mounted on the frame 1. The second vibrating feeder 41 is mounted side by side with the first vibrating feeder 31 on the frame 1, and its conveying surface width is smaller than that of the first vibrating feeder 31. This allows for the conveying of small quantities of material, facilitating accurate counting in the later stages of counting. Specifically, the structure of the second conveying device 4 is the same as that of the first conveying device 3, and its other structural components will not be further described here. When counting materials, since the continuous falling material in the early stages of counting does not directly affect the accuracy of the later accurate counting, the first vibrating feeder 31 with a larger conveying surface width is selected in the early stages of counting, which can effectively improve the counting efficiency. When the measured quantity is close to the preset value, a small amount of material is then conveyed to the receiving device 7 through the second vibrating feeder 41 with a smaller conveying surface width. The visual counting device 6 counts the material falling from the discharge end of the second vibrating feeder 41 one by one to ensure the accuracy of the final counting result.

[0034] The material feeding mechanism 5, located in front of the receiving hopper 2, pushes the material on the first vibrating feeder 31 and the second vibrating feeder 41 forward. It includes a feeding roller 51 and a rotating motor 52. The feeding roller 51 is rotatably mounted on the frame 1, pushing the material falling onto the first vibrating feeder 31 and the second vibrating feeder 41 forward. The rotating motor 52 is mounted on the frame 1, connected to and driving the feeding roller 51 to rotate. Specifically, the feeding roller 51 includes a feeding roller body 53, a first feeding assembly, and a second feeding assembly. The feeding roller body 53 is rotatably mounted on the frame 1. The first feeding assembly is mounted on the feeding roller body 53 and connected to the first vibrating feeder 31. In contrast, the first feeding plate 54 is circumferentially distributed on the feeding roller body 53; the second feeding assembly is disposed on the feeding roller body 53, opposite to the second vibrating feeder 41, and includes a plurality of second feeding plates 55 circumferentially distributed on the feeding roller body 53, and the feeding area of ​​the second feeding plate 55 is smaller than that of the first feeding plate 54, so that the first feeding plate 54 can feed more material into the first vibrating feeder 31; through the setting of the feeding roller 51, the material coming out of the discharge port 211 can move forward into the first vibrating feeder 31 or the second vibrating feeder 41, preventing it from accumulating at the discharge port 211 and affecting the operation of the receiving hopper 2.

[0035] A visual counting device 6, installed in the frame 1, counts the materials entering the receiving device 7. When the quantity of materials entering the receiving device 7 approaches a preset value, the first vibrating feeder 31 stops working, and the second vibrating feeder 41 starts working to convey materials into the receiving device 7. Specifically, the visual counting device 6 includes a counting camera 61 and a mounting bracket 62. The counting camera 61 is installed in the frame 1 to capture images of materials falling from the discharge ends of the first vibrating feeder 31 and the second vibrating feeder 41. The mounting bracket 62 is installed in the frame 1 to mount the counting camera 61. Furthermore, the counting camera 61 can be an industrial camera to capture images of materials falling from the first vibrating feeder 31 and the second vibrating feeder 41, thereby determining the quantity of materials falling. Using a camera to capture images of items and then determine the quantity is a conventional technology, and its specific working principle will not be further elaborated here.

[0036] Receiving device 7, mounted on frame 1 and opposite to the discharge ends of the first vibrating feeder 31 and the second vibrating feeder 41, is used to temporarily store counted materials. It includes multiple receiving bins 71, a rotating assembly, and a guide hopper 73. The multiple receiving bins 71 are rotatably mounted on frame 1, opposite to the discharge ends of the first and second vibrating feeders 31 and 41. The rotating assembly connects to and drives the multiple receiving bins 71 to rotate, and includes a rotating disk 72 and a rotating component. The rotating disk 72 is rotatably mounted on frame 1, and the multiple receiving bins 71 are circumferentially arranged on the rotating disk 72. The rotating component connects to and drives the rotating disk. The rotating disc 72 can be driven by a motor. The guide hopper 73 is mounted on the frame 1, opposite to the discharge ends of the first vibrating feeder 31 and the second vibrating feeder 41, guiding the material into the receiving device 7. It is equipped with a discharge port opposite to the receiving hopper 71. The counting camera 61 is opposite to the discharge port to capture images of the material falling from the discharge port. By setting multiple receiving hoppers 71 to work with the rotating assembly, the work can be completed in one receiving hopper, allowing another receiving hopper to quickly rotate to the working state, ensuring the continuity of the counting process and facilitating the transfer of the counted material.

[0037] The control device 8 connects to and controls the operation of the first transmission device 3, the second transmission device 4, the visual counting device 6, and the receiving device 7. It includes a controller and a display screen 81. The display screen 81 can be used to display the information fed back by the counting camera 61. Specifically, the controller can be a PLC controller or other controllers that can achieve the corresponding effect.

[0038] During operation, the required measured material is fed into the receiving hopper 2 and falls downwards through the discharge port 211 onto either the first vibrating feeder 31 or the second vibrating feeder 41. The first vibrating feeder 31 is then controlled to operate, conveying material into the receiving hopper 71. A counting camera 61 monitors the material falling from the guide hopper 73 in real time and feeds the collected information back to the controller. When the measured quantity of material approaches the preset value, the first vibrating feeder 31 stops operating, and the second vibrating feeder 41 starts operating, conveying a small amount of material into the receiving hopper 71. Because the conveying surface width of the second vibrating feeder 41 is small, the material falls one by one from the discharge end of the second vibrating feeder 41 into the guide hopper 73, where the counting camera 61 counts each piece, ensuring the receiving hopper 71 contains an accurate quantity of material. At this time, the rotating disc 72 rotates, causing another empty receiving hopper to rotate to face the guide hopper 73, and the operator then packages the measured material.

[0039] The counting machine specified in this application has a simple structure and can accurately count medicines in capsule or tablet form, improving counting accuracy. Specifically, the counting machine's structure is defined as follows: through the cooperation of the first conveying device 3 and the second conveying device 4, in the early stage of counting, the first vibrating feeder 31 with a large conveying surface conveys the material to the receiving device 7, effectively improving counting efficiency; when the material entering the receiving device 7 approaches the preset value, the operation of the first vibrating feeder 31 is stopped, and the operation of the second vibrating feeder 41 is controlled. The second vibrating feeder 41 with a small conveying surface conveys a small amount of material into the receiving device 7, and then the visual counting device 6 counts them one by one to ensure the accuracy of the counting results.

[0040] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model application and the contents of the specification should still fall within the scope of the present utility model application.
