Description

Technical Field

[0001] This utility model relates to the technical field of disinfectant tablet production, and in particular to an automatic disinfectant tablet counting device. Background Technology

[0002] After disinfectant tablets are produced, they need to be packaged. During packaging, the tablets need to be counted, and a certain number of tablets are fed into packaging bottles or bags for quantitative packaging. Chinese invention patent CN108688899A discloses an automatic tablet counting device. This device includes a dosing tank, a tablet separating device, an infrared sensor, a display screen, and a controller. The dosing tank includes a box body, two support legs, a tablet collecting funnel, and a tablet arranging funnel. The tablet collecting funnel is located inside the box body. The tablet arranging funnel is located directly above the tablet collecting funnel and has an arranging channel for the tablets to pass through vertically in sequence. The tablet separating device includes a vibrator, a bracket, an impeller, and a drive motor, mainly used to push the tablets at the bottom of the arranging channel into the tablet collecting funnel in sequence. The controller monitors the falling tablets through the infrared sensor, counts the falling tablets, and displays the calculated number of tablets on the display screen.

[0003] However, the existing technology uses infrared sensors to count the tablets, which then fall directly into the receiving area. When the tablets or disinfectant tablets fall from a great height, they are easily broken. Moreover, the disinfectant tablets fall in bulk into the receiving area after counting and need to be collected and placed in packaging bottles or bags, which is not conducive to improving work efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic disinfection tablet counter that can discharge a whole batch of disinfection tablets into packaging bottles or bags, which can prevent the disinfection tablets from falling and breaking, and improve work efficiency.

[0005] This utility model discloses an automatic counting device for disinfectant tablets, including a conveyor belt for transporting disinfectant tablets; it also includes a fixed guide plate, a movable guide plate, a sorting plate, a photoelectric switch, an end plate, and a receiving assembly. The fixed guide plate is fixedly installed on the upper left side of the conveyor belt, and the movable guide plate is movably installed on the upper right side of the conveyor belt. The front part of the movable guide plate is tilted to the right, and the rear part of the movable guide plate is parallel to the fixed guide plate. The sorting plate is installed between the fixed guide plate and the movable guide plate, with a gap between the sorting plate and the conveyor belt for one disinfectant tablet to pass through. The photoelectric switch is installed on the rear side wall of the sorting plate. The end plate is vertically installed at the lower rear end of the conveyor belt. The receiving assembly is liftably installed on the rear side wall of the end plate, with an inlet on the side of the receiving assembly facing the end plate and an outlet at the bottom of the receiving assembly. During operation, the conveyor belt transports the disinfectant tablets backward. When the disinfectant tablets pass through the sorting plate, the sorting plate sorts the stacked disinfectant tablets. The disinfectant tablets are blocked, causing them to lay flat on the conveyor belt. The front of the moving guide plate guides the tablets towards the fixed guide plate, causing them to line up and enter between the rear of the fixed and moving guide plates. When a tablet passes the photoelectric switch, the switch generates an electrical signal, which counts the tablets once. The counted tablets then enter the receiving assembly through the inlet. After entering the receiving assembly, it descends along the end plate, with the descent height equal to the thickness of the tablet. When the photoelectric switch reaches the set value and the receiving assembly descends to the set height, the counting of one batch is completed. The outlet of the receiving assembly opens, allowing all the tablets in this batch to be discharged into the packaging bottle or bag below the receiving assembly. This prevents the tablets from falling and breaking, and the neatly packaged tablets fall into the packaging bottle or bag after counting, improving work efficiency.

[0006] Preferably, it also includes two slide rails and two sliders. The two slide rails are respectively installed on the outer side walls of the fixed guide plate and the moving guide plate, and the two sliders are respectively slidably installed on the two slide rails. The two ends of the material sorting plate are respectively installed on the two sliders. When adjusting the distance between the moving guide plate and the fixed guide plate, the position of the two slide rails is appropriately adjusted along the two slide rails, so that the material sorting plate follows the moving guide plate to tilt adaptively, so that the gap between the fixed guide plate and the moving guide plate can adapt to disinfection tablets of different diameters, and has good versatility.

[0007] Preferably, it also includes two plate frames, which are rotatably mounted on two sliders respectively. The two ends of the material sorting plate are slidably connected to the two plate frames respectively. The two ends of the material sorting plate slide up and down along the two plate frames respectively, thereby adjusting the gap between the lower end of the material sorting plate and the conveyor belt, adapting to disinfection sheets of different thicknesses and improving versatility.

[0008] Preferably, the device also includes a tray and a contact switch. The tray is installed at the rear end of the conveyor belt, with its upper surface flush with the upper surface of the conveyor belt. The rear edge of the tray slides into contact with the inlet of the receiving component. The contact switch is installed on the lower surface of the tray, with its contact end extending above the tray through a clearance hole. The tray holds the disinfectant tablet and guides it towards the inlet of the receiving component. When the disinfectant tablet passes the contact end of the contact switch, the contact switch generates an electrical signal. The electrical signal counts the disinfectant tablets entering the receiving component. The receiving component descends in steps according to the electrical signal, improving the counting accuracy of the disinfectant tablets entering the receiving component.

[0009] Preferably, the receiving assembly includes a surrounding plate, a baffle, a torsion spring, a limiting plate, and bolts. The surrounding plate has an L-shaped cross-section and is provided with longitudinal side plates and a transverse rear plate. The front opening of the surrounding plate is an inlet, and the lower opening is an outlet. The side plates of the surrounding plate are slidably connected to the outer walls of the end plates. The rear end of the baffle is rotatably connected to the lower rear end of the surrounding plate. The two ends of the torsion spring are connected to the two surrounding plates and the baffle, respectively. The elastic force of the torsion spring causes the baffle to block the outlet of the surrounding plate. The limiting plate is slidably mounted on the rear plate of the surrounding plate, and the front edge of the surrounding plate is slidably connected to the end plate. Next, the rear edge of the enclosure is slidably connected to the rear plate of the enclosure, and the rear end of the limiting plate is connected to the sliding groove on the rear plate of the enclosure by bolts; the limiting plate moves along the rear plate of the enclosure, the gap between the limiting plate and the side plate of the enclosure is adjusted and locked by bolts, so as to adapt to disinfection tablets of different diameters, with good versatility. The space enclosed by the end plate, enclosure, and baffle is the batch loading area for disinfection tablets. When the batch loading area is full of disinfection tablets, the counting of a batch is completed. Open the baffle to discharge the entire batch of disinfection tablets, which is practical.

[0010] Preferably, it also includes a rack, a stepper motor, and a gear. The rack is vertically mounted on the side plate of the enclosure, the stepper motor is mounted on the conveyor belt, and the output shaft of the stepper motor is concentrically mounted with a gear that meshes with the rack. After receiving a signal, the stepper motor drives the gear to rotate a certain angle and then stops, so that the gear meshes with the rack to drive the enclosure and the limiting plate to descend by the thickness of a disinfection sheet. The drive is stable and reliable. By programming the stepper motor, automation can be achieved, improving work efficiency.

[0011] Preferably, it also includes two spring rods, two open retaining plates, two slide rails, two sliders, and two shafts. The rear ends of the two spring rods are rotatably mounted on the left and right sides of the rear of the baffle, respectively. An elastic component is provided between the two spring rods and the baffle, which causes the two spring rods to tilt forward and downward at a certain angle. Open retaining plates are installed at the front ends of both spring rods. The two slide rails are vertically mounted on the front end face of the end plate. The two sliders are slidably mounted on the two slide rails. Shafts are installed on both sliders, and the two shafts match the two open retaining plates. After adjusting the position of the two sliders on the two slide rails according to the quantity of a batch of disinfectant tablets, they are locked. As the number of disinfectant tablets between the enclosure and the limiting plate gradually increases, the enclosure gradually descends, causing the two opening clamps to engage with the two shafts respectively. The enclosure continues to descend, compressing the two spring rods and causing them to gradually tilt and rotate forward and upward. When the baffle is below the two shafts, the two spring rods rotate to tilt forward and upward. At this point, the elastic force of the two spring rods returns them to their original position and extends, pushing the baffle downward and opening it, automatically discharging a batch of disinfectant tablets. The enclosure then rises and returns to its original position. After the two opening clamps disengage from the two shafts, the torsion spring drives the baffle to return to its original position, and the two spring rods return to their original position under the action of the elastic components, preparing for the next discharge and improving work efficiency.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: During operation, the conveyor belt transports the disinfection tablets backward. When the disinfection tablets pass the sorting plate, the sorting plate blocks the stacked disinfection tablets, causing the disinfection tablets to be laid flat on the conveyor belt. The front part of the moving guide plate guides the disinfection tablets towards the fixed guide plate, so that the disinfection tablets are arranged in a row and enter between the rear parts of the fixed guide plate and the moving guide plate. When the disinfection tablets pass the photoelectric switch, the photoelectric switch generates an electrical signal. Each electrical signal generates a count. The counted disinfection tablets enter the receiving component through the inlet. After the disinfection tablets enter the receiving component, the receiving component descends along the end plate. The descending height of the receiving component is equal to the thickness of the disinfection tablets. When the photoelectric switch reaches the set value and the receiving component descends to the set height, the counting of one batch is completed. The outlet of the receiving component opens, allowing all the disinfection tablets in this batch to be discharged into the packaging bottle or bag below the receiving component, avoiding the disinfection tablets from falling and breaking. Moreover, the counted disinfection tablets fall into the packaging bottle or bag in a complete package, improving work efficiency. Attached Figure Description

[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0021] Example 1

[0022] like Figures 1 to 3 and Figure 6 As shown, an automatic counting device for disinfectant tablets includes a conveyor belt 1 for conveying disinfectant tablets; it also includes a fixed guide plate 2, a movable guide plate 3, a sorting plate 4, a photoelectric switch 5, an end plate 6, and a receiving assembly 7. The fixed guide plate 2 is fixedly installed on the upper left side of the conveyor belt 1, and the movable guide plate 3 is movably installed on the upper right side of the conveyor belt 1. The front part of the movable guide plate 3 is inclined to the right, and the rear part of the movable guide plate 3 is parallel to the fixed guide plate 2. The sorting plate 4 is installed between the fixed guide plate 2 and the movable guide plate 3. A gap is provided between the sorting plate 4 and the conveyor belt 1 to allow one disinfectant tablet to pass through. The photoelectric switch 5 is installed on the end plate 6. On the rear side wall of the material plate 4, the end plate 6 is vertically installed at the lower rear end of the conveyor belt 1. The receiving component 7 is vertically mounted on the rear side wall of the end plate 6. The receiving component 7 has an inlet on the side facing the end plate 6 and an outlet at the bottom. It also includes a support plate 11 and a contact switch 12. The support plate 11 is installed at the rear end of the conveyor belt 1. The upper end face of the support plate 11 is flush with the upper end face of the conveyor belt 1. The rear edge of the support plate 11 slides and connects with the inlet of the receiving component 7. The contact switch 12 is installed on the lower end face of the support plate 11. The contact end of the contact switch 12 extends above the support plate 11 through a clearance hole.

[0023] During operation, conveyor belt 1 transports the disinfectant tablets backward. When the tablets pass the sorting plate 4, the sorting plate 4 blocks the stacked tablets, causing them to lay flat on conveyor belt 1. The front of the moving guide plate 3 guides the tablets towards the fixed guide plate 2, causing them to line up and enter between the rear of the fixed guide plate 2 and the moving guide plate 3. When a tablet passes the photoelectric switch 5, the photoelectric switch 5 generates an electrical signal, which counts once. The support plate 11 holds the tablet and guides it towards the inlet of the receiving component 7. When a tablet passes the contact end of the contact switch 12, the contact switch 12 generates a second electrical signal. This second electrical signal triggers the flow of the disinfectant tablets into the receiving component 7. The counting of disinfectant tablets improves the accuracy of counting the tablets entering the receiving component 7. After being counted, the disinfectant tablets enter the receiving component 7 through the inlet. After the disinfectant tablets enter the receiving component 7, the receiving component 7 descends stepwise along the end plate 6 according to the second electrical signal. The descent height of the receiving component 7 is equal to the thickness of the disinfectant tablet. When the photoelectric switch 5 reaches the set value and the receiving component 7 descends to the set height, the counting of one batch is completed. The outlet of the receiving component 7 opens, allowing all the disinfectant tablets in this batch to be discharged into the packaging bottle or bag below the receiving component 7, preventing the disinfectant tablets from falling and breaking. Moreover, the counted disinfectant tablets fall into the packaging bottle or bag in a complete package, improving work efficiency.

[0024] Example 2

The two ends of the material sorting plate 4 are respectively slidably connected to the two plate frames 10.

[0026] When adjusting the distance between the moving guide plate 3 and the fixed guide plate 2, the positions of the two slide rails 8 are adjusted appropriately along the two slide rails 8, so that the material sorting plate 4 follows the moving guide plate 3 to tilt adaptively, so that the gap between the fixed guide plate 2 and the moving guide plate 3 can accommodate disinfection sheets of different diameters. The two ends of the material sorting plate 4 slide up and down along the two plate frames 10 respectively, thereby adjusting the gap between the lower end of the material sorting plate 4 and the conveyor belt 1 to accommodate disinfection sheets of different thicknesses and improve versatility.

[0027] Example 3

[0028] like Figures 1 to 4As shown, based on Embodiment 1, the receiving component 7 includes a surrounding plate 13, a baffle 14, a torsion spring 15, a limiting plate 16, and bolts 17. The surrounding plate 13 has an L-shaped cross-section and is provided with longitudinal side plates and a transverse rear plate. The front opening of the surrounding plate 13 is the inlet, and the lower opening of the surrounding plate 13 is the outlet. The side plates of the surrounding plate 13 are slidably connected to the outer wall of the end plate 6. The rear end of the baffle 14 is rotatably connected to the lower rear end of the surrounding plate 13. The two ends of the torsion spring 15 are respectively connected to the two surrounding plates 13 and the baffle 14. The elastic force of the torsion spring 15 causes the baffle 14 to block the outlet of the surrounding plate 13. The limiting plate 16 is slidably mounted on the rear plate of the surrounding plate 13. The front edge of the surrounding plate 13 is slidably connected to the end plate 6, and the rear edge of the surrounding plate 13 is slidably connected to the rear plate of the surrounding plate 13. The rear end of the limiting plate 16 is connected to the groove on the rear plate of the surrounding plate 13 by bolts 17. It also includes a rack 18 and a stepper motor 19. The assembly includes a gear 20 and a rack 18, which are vertically mounted on the side plate of the enclosure 13. A stepper motor 19 is mounted on the conveyor belt 1, and the output shaft of the stepper motor 19 is concentrically mounted with the gear 20, which meshes with the rack 18. It also includes two spring rods 21, two open clamping plates 22, two slide rails 23, two sliders 24, and two shafts 25. The rear ends of the two spring rods 21 are rotatably mounted on the left and right sides of the rear of the baffle 14. An elastic component is provided between the two spring rods 21 and the baffle 14, causing the two spring rods 21 to tilt forward and downward at a certain angle. The front ends of both spring rods 21 are mounted with open clamping plates 22. The two slide rails 23 are vertically mounted on the front end face of the end plate 6. The two sliders 24 are slidably mounted on the two slide rails 23, and shafts 25 are mounted on both sliders 24. The two shafts 25 are matched with the two open clamping plates 22.

[0029] The limiting plate 16 moves along the rear plate of the surrounding plate 13, adjusting the gap between the limiting plate 16 and the side plate of the surrounding plate 13 and locking it with bolts 17, thus accommodating disinfection tablets of different diameters. The two sliders 24 are adjusted and locked on the two slide rails 23 according to the quantity of disinfection tablets in a batch, ensuring good versatility. The space enclosed by the end plate 6, the surrounding plate 13, and the baffle 14 is the batch loading area for disinfection tablets. After receiving a signal, the stepper motor 19 drives the gear 20 to rotate a certain angle and then stops, causing the gear 20 to mesh with the rack 18, driving the surrounding plate 13 and the limiting plate 16 to descend by the thickness of one disinfection tablet. Automation can be achieved by programming the stepper motor 19. As the number of disinfection tablets between the surrounding plate 13 and the limiting plate 16 gradually increases, the surrounding plate 13 gradually descends, causing the two openings to... Plate 22 is engaged with two shafts 25 respectively. The surrounding plate 13 continues to descend, compressing the two spring rods 21 and causing them to gradually tilt and rotate forward and upward. When the batch loading area is filled with disinfectant tablets, the counting of one batch is completed. At this time, the baffle 14 is located below the two shafts 25. The two spring rods 21 rotate to tilt forward and upward. The elastic force of the two spring rods 21 extends them, pushing the baffle 14 downward to open and automatically discharging the batch of disinfectant tablets. After the discharge is completed, the stepper motor 19 reverses to raise and reset the surrounding plate 13. When the two opening clamping plates 22 disengage from the two shafts 25, the torsion spring 15 drives the baffle 14 to reset. The two spring rods 21 reset under the action of the elastic component, preparing for the next discharge and improving work efficiency.

[0030] like Figures 1 to 6 As shown, this utility model discloses an automatic disinfectant tablet counter. During operation, the conveyor belt 1 first transports the disinfectant tablets backward. When the tablets pass the sorting plate 4, the sorting plate 4 blocks the stacked tablets, causing them to lay flat on the conveyor belt 1. The front of the moving guide plate 3 guides the tablets towards the fixed guide plate 2, causing them to line up and enter between the rear of the fixed guide plate 2 and the moving guide plate 3. Then, when a tablet passes the photoelectric switch 5, the switch generates an electrical signal, which counts the tablets once. The counted tablets then enter the tray 11, which holds them and guides them towards the inlet of the receiving component 7. Finally, when the tablets pass the contact... When the contact end of switch 12 is reached, switch 12 generates an electrical signal 2. The electrical signal 2 counts the disinfectant tablets entering the receiving component 7. After receiving the electrical signal 2, stepper motor 19 drives gear 20 to rotate a certain angle and then stops, so that gear 20 meshes with rack 18 to drive the enclosure plate 13 and limit plate 16 to descend by the thickness of one disinfectant tablet. The disinfectant tablets enter between enclosure plate 13 and limit plate 16 through the inlet. When the receiving component 7 descends to the set height, the counting of one batch is completed. Finally, two spring rods 21, together with two open clamping plates 22 and two shaft rods 25, open the baffle 14, so that all the disinfectant tablets in this batch are discharged into the packaging bottle or bag below the receiving component 7.
