Abstract
Description
Technical Field
[0001] This utility model belongs to the field of product counting technology, and in particular relates to a counting device for products on a conveyor belt line. Background Technology
[0002] In industrial production lines for products such as fertilizers and cement, it is often necessary to count the number of the smallest, final-packaged, marketable product units. Product counting is a core foundation of data for production operations, quality management, inventory control, cost accounting, and logistics. Accurate and real-time product counting is an indispensable key element for factories to achieve efficient, lean, and traceable management.
[0003] A search revealed a counting conveyor belt with publication number CN218402225U on the Chinese Patent website. This counting device can be used for product counting on the production line, but it has some defects and shortcomings that need to be improved: (1) Some existing counting devices lack effective dust removal measures. When using optical counting equipment to count products on the conveyor belt, dust and other impurities floating in the air can easily cover the optical counting equipment and interfere with the light beam it generates. This not only affects the service life of the optical counting equipment, but also leads to an increase in the misjudgment rate of the optical counting equipment; (2) Due to the structural design of some existing counting devices, when multiple products are placed side by side in the same position on the conveyor belt, the counting equipment often has difficulty distinguishing them during counting and can only identify them as a single product, resulting in missed counting. Therefore, in view of the above problems, the counting device for products on the conveyor belt line provided by this utility model is of great significance. Utility Model Content
[0004] This utility model provides a counting device for products on a conveyor belt line. The conveyor mechanism can transfer products such as fertilizer and cement to other stages of the production line. During this process, a counting component can count the products on the conveyor mechanism. A dust removal mechanism helps to remove dust and other impurities from covering the counting component and interfering with the infrared beam it generates, thus affecting the lifespan of the counting component and increasing its false alarm rate. A guiding component guides the products on the conveyor mechanism, ensuring that the products are arranged in a straight line along the conveyor belt. This effectively prevents multiple products from being placed side-by-side in the same position on the conveyor belt, which could lead to inaccurate identification by the counting component and missed counts. In summary, this invention solves the problems in the background technology.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model discloses a counting device for products on a conveyor belt line, comprising a base, a fixed frame and two pairs of roller frames fixedly connected to the top of the base, the two pairs of roller frames being symmetrically distributed on both sides of the fixed frame, and a conveying mechanism being provided on the roller frames; the fixed frame is n-shaped, with several positioning holes on both sides, and a counting component and a dust removal mechanism being provided on both sides and the top of the fixed frame; a fixed seat is fixedly connected to one side of the fixed frame, and a guide component is provided on the fixed seat;
[0007] The conveying mechanism includes a motor and a pair of conveying rollers. The pair of conveying rollers are respectively located between two pairs of roller frames. The motor is mounted on one pair of roller frames, and a roller shaft is installed between the other pair of roller frames. One of the conveying rollers is mounted on the output shaft of the motor, and the other conveying roller is movably connected to the shaft of the roller shaft. A conveyor belt is connected between the two conveying rollers.
[0008] The counting component includes a pair of mounting bases, one side of which is equipped with a photoelectric sensor, and the other side of which is fixedly connected with a plurality of studs, each stud being threaded with a nut that mates with it.
[0009] The dust removal mechanism includes an exhaust fan and a dust collection chamber. The exhaust fan and the dust collection chamber are respectively installed on the upper and lower surfaces of the fixed frame. An exhaust pipe is installed on the exhaust fan. The end of the exhaust pipe passes through the top of the fixed frame and is connected to the inner cavity of the dust collection chamber. Several dust collection pipes are opened at the bottom of the dust collection chamber. Side plates are fixedly connected to the outer walls on both sides of the dust collection chamber. A dust collection plate is installed between the side plates. A dust collection net is installed on the dust collection plate.
[0010] The guide assembly includes a pair of electrically operated telescopic rods, which are respectively mounted on each fixed base, and a guide plate is fixedly connected to the end of the output shaft of each of the electrically operated telescopic rods.
[0011] Furthermore, the surface of the conveyor belt is provided with herringbone anti-slip texture.
[0012] Furthermore, the pair of photoelectric sensors are both located above the conveyor belt, with their centers at the same height. The number of studs is the same as the number of positioning holes, and their diameters correspond to the diameters of the positioning holes. The center of each stud corresponds one-to-one with the center of each positioning hole.
[0013] Furthermore, the suction pipes are located directly above the conveyor belt, and each suction pipe is equidistantly linearly distributed along the length of the suction chamber.
[0014] Furthermore, the inner sidewall of the side plate is provided with a slot, the dust suction plate is located below the dust suction pipe, and both sides of the dust suction plate are fixedly connected with a block. Both the block and the slot are rectangular, and the thickness of the block is equal to the width of the slot.
[0015] Furthermore, the guide plate is inclined outward at the end away from the fixed frame and is symmetrically distributed on both sides of the conveyor belt, and the bottom height of the guide plate is level with the top height of the conveyor belt.
[0016] Furthermore, a buffer pad is provided on the inner sidewall surface of the guide plate.
[0017] The present invention has the following advantages over the prior art:
[0018] (1) When the counting device for products on a conveyor belt line in this utility model is in use, fertilizers, cement and other products can be transferred to other links of the production line through the conveying mechanism. At this time, the counting component can count the products on the conveying mechanism. In this process, the dust removal mechanism can play the role of dust removal to avoid dust and other impurities covering the counting component and interfering with the infrared beam generated by it, thus affecting the service life of the counting component and causing its misjudgment rate to increase.
[0019] (2) When the counting device for products on a conveyor belt line in this utility model is used, the product on the conveyor mechanism can be guided by the guide component to ensure that the product is arranged in a straight line along the conveyor belt, thereby effectively preventing multiple products from being placed side by side in the same position on the conveyor belt, which would cause the counting component to fail to identify the products accurately and result in missed counting.
[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0033] In the description of this utility model, it should be understood that the terms "relative", "one end", "inner", "lateral", "end", "both ends", "both sides", "front", "one end face", "the other end face", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0034] Please see Figure 1-8As shown, a counting device for products on a conveyor belt line according to the present invention includes a base 1. A fixed frame 2 and two pairs of roller frames 3 are fixedly connected to the top of the base 1. The two pairs of roller frames 3 are symmetrically distributed on both sides of the fixed frame 2, and a conveying mechanism is provided on the roller frames 3. The fixed frame 2 is n-shaped, and several positioning holes 4 are opened on both sides. Counting components and dust removal mechanisms are respectively provided on both sides and the top of the fixed frame 2. A fixed seat 5 is fixedly connected to one side of the fixed frame 2, and a guide component is provided on the fixed seat 5.
[0035] The conveying mechanism includes a motor 6 and a pair of conveying rollers 7. The pair of conveying rollers 7 are located between two pairs of roller frames 3. The motor 6 is mounted on one pair of roller frames 3, and a roller shaft 8 is installed between the other pair of roller frames 3. One of the conveying rollers 7 is mounted on the output shaft of the motor 6, and the other conveying roller 7 is movably connected to the shaft of the roller shaft 8. A conveyor belt 9 is connected between the two conveying rollers 7. Products such as fertilizer and cement are placed on the conveyor belt 9. The motor 6 can drive the conveying rollers 7 to rotate. When the conveying rollers 7 rotate, they can drive the conveyor belt 9 to move so as to transfer the products to other stages of the production line.
[0036] The counting assembly includes a pair of mounting bases 10. A photoelectric sensor 11 is mounted on one side of the mounting base 10, and several studs 12 are fixedly connected to the other side of the mounting base 10. Each stud 12 is threaded with a nut 13 that mates with it. One photoelectric sensor 11 is the transmitting end, and the other photoelectric sensor 11 is the receiving end. The photoelectric sensor 11 is connected to an external counter. The counter can be a commercially available PLC or a dedicated counting module. When the product moves between the two photoelectric sensors 11 with the conveyor mechanism, the infrared beam generated by the photoelectric sensor 11 at the transmitting end will be blocked by the product. At this time, the resistance of the photoelectric sensor 11 at the receiving end changes, thereby outputting a pulse signal to the external counter. The external counter receives the pulse signal and accumulates the count, thus realizing the counting of products on the production line.
[0037] The dust removal mechanism includes an exhaust fan 14 and a dust collection chamber 15. The exhaust fan 14 and the dust collection chamber 15 are respectively installed on the upper and lower surfaces of the fixed frame 2. An exhaust pipe 16 is installed on the exhaust fan 14, and the end of the exhaust pipe 16 passes through the top of the fixed frame 2 and communicates with the inner cavity of the dust collection chamber 15. Several dust collection pipes 17 are opened at the bottom of the dust collection chamber 15, and side plates 18 are fixedly connected to the outer walls on both sides of the dust collection chamber 15. Dust collection plates 19 are installed between the side plates 18, and dust collection nets 20 are installed on the dust collection plates 19. The dust collection mechanism is activated by driving the exhaust fan 14. The dust collection chamber 15 can be ventilated by the exhaust pipe 16. When a negative pressure is generated inside the dust collection chamber 15, dust and other impurities floating in the air around the counting component can be sucked upward through each suction pipe 17 until the impurities come into contact with the dust collection net 20. At this time, the dust and other impurities will be adsorbed on the surface of the dust collection net 20 to achieve the purpose of dust removal. This effectively avoids dust and other impurities covering the photoelectric sensor 11 in the counting component and interfering with the infrared beam it generates, thus affecting the service life of the photoelectric sensor 11 and causing its misjudgment rate to increase.
[0038] The guide assembly includes a pair of electric telescopic rods 21, which are respectively installed on each fixed base 5. Each electric telescopic rod 21 has a guide plate 22 fixedly connected to the end of its output shaft. By driving the electric telescopic rod 21, the guide plate 22 is moved towards the product until the guide plate 22 is respectively attached to both sides of the product. The spacing of the guide plates 22 can be adjusted according to the width of products such as fertilizer and cement.
[0039] The surface of the conveyor belt 9 is provided with herringbone anti-slip texture. The anti-slip texture can increase the friction between the product and the conveyor belt 9 to prevent the product from slipping during the conveying process.
[0040] In this setup, a pair of photoelectric sensors 11 are both located above the conveyor belt 9, with their centers at the same height. The number of studs 12 is the same as the number of positioning holes 4, and their diameters correspond to the diameters of the positioning holes 4. The center of each stud 12 corresponds one-to-one with the center of each positioning hole 4. Each stud 12 can be aligned and pass through the corresponding positioning hole 4. At this time, the nut 13 is threaded onto each stud 12. Through the mutual cooperation between the studs 12, positioning holes 4, and nut 13, the counting component can be fixed at a designated position on the mounting frame 2, so that the centers of the two photoelectric sensors 11 are at the same height. This ensures that the photoelectric sensor 11 at the receiving end can accurately receive the infrared beam generated by the photoelectric sensor 11 at the transmitting end. By unscrewing the nut 13, the counting component can be removed from the mounting frame 2 for maintenance and replacement.
[0041] The suction pipe 17 is located directly above the conveyor belt 9, and each suction pipe 17 is equidistantly linearly distributed along the length of the suction chamber 15. The suction range of the dust removal mechanism can be expanded by multiple suction pipes 17 so that it can fully cover the area around the counting component, thereby effectively improving the dust removal efficiency and effect.
[0042] The inner side wall of the side panel 18 is provided with a slot 23. The dust suction plate 19 is located below the dust suction pipe 17, and both sides of the dust suction plate 19 are fixedly connected with a block 24. Both the block 24 and the slot 23 are rectangular, and the thickness of the block 24 is equal to the width of the slot 23. The block 24 can be aligned and inserted into the corresponding slot 23 to fix the dust suction plate 19 by plugging it in. When the dust suction net 20 is covered with a lot of dust and other impurities due to long-term use, the dust suction plate 19 can be removed from between the side panels 18 by sliding the block 24 out of the slot 23 so that the dust suction net 20 can be cleaned regularly.
[0043] The guide plate 22 is inclined outward at the end away from the fixed frame 2 and is symmetrically distributed on both sides of the conveyor belt 9. The bottom height of the guide plate 22 is level with the top height of the conveyor belt 9. When the conveying mechanism moves the products, the guide plate 22 can guide the products on the conveyor belt 9 to ensure that the products are arranged in a straight line along the conveyor belt 9. This can effectively prevent multiple products from being placed side by side in the same position on the conveyor belt 9, which would cause the counting component to fail to identify them accurately and result in missed counting.
[0044] The inner sidewall surface of the guide plate 22 is provided with a buffer pad 25. The buffer pad 25 can be made of elastic materials such as sponge and is fixed by adhesives. The buffer pad 25 can play a buffering and protective role to prevent the product from directly contacting the guide plate 22 and causing collision and wear.
[0045] The circuits, electronic components, and chip modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.
[0046] All standard parts used in the application documents can be purchased from the market. All components in this application document can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The electrical components mentioned in this document are all electrically connected to the external main controller and power supply, and the main controller is a conventional known device that can play a control role.
[0047] The working principle of this utility model is as follows:
[0048] In use, fertilizers, cement, and other products can be placed on the conveyor belt 9. The drive motor 6 then rotates the conveyor roller 7, which in turn moves the conveyor belt 9 to transfer the products to other stages of the production line. When a product moves between two photoelectric sensors 11, the infrared beam emitted by the emitting photoelectric sensor 11 is blocked by the product. At this time, the resistance of the receiving photoelectric sensor 11 changes, causing it to output a pulse signal to an external counter. The external counter receives the pulse signal and accumulates the count, thus counting the products on the production line. While counting the products, the exhaust fan 14 can be driven to ventilate the dust collection chamber 15 through the exhaust pipe 16. When a negative pressure is generated inside the dust collection chamber 15, dust and other particles floating in the air around the counting components can be removed through the various suction pipes 17. Impurities are drawn upwards until they come into contact with the dust collection net 20. At this point, dust and other impurities are adsorbed onto the surface of the dust collection net 20 to achieve the purpose of dust removal. This effectively prevents dust and other impurities from covering the photoelectric sensor 11 in the counting component and interfering with the infrared beam it generates, thus affecting the service life of the photoelectric sensor 11 and increasing its false judgment rate. When the conveying mechanism moves the products, the electric telescopic rod 21 can be driven to move the guide plate 22 towards the product until the guide plate 22 is attached to both sides of each product. The spacing of the guide plate 22 can be adjusted according to the width of products such as fertilizer and cement. At this time, the guide plate 22 can guide the products on the conveyor belt 9 to ensure that the products are arranged in a straight line along the conveyor belt 9. This effectively prevents multiple products from being placed side by side in the same position on the conveyor belt 9, which would cause the counting component to fail to identify them accurately and result in missed counting.
