Description
Technical Field
[0001] This invention relates to the field of disinfectant production technology, specifically to a continuous automatic coding device and coding method for disinfectant production. Background Technology
[0002] Disinfectants are chemical agents used to kill or inhibit microorganisms such as bacteria, viruses, and fungi, and are widely used in medical, hygiene, and household cleaning fields. They effectively disrupt the cell structure of microorganisms, preventing their reproduction and thus ensuring the hygiene and safety of the environment and goods. Most existing disinfectant production processes involve filling the bottles with sterilized bottles, and then using a coding device to print the production date onto the bottles so that consumers can check the information when purchasing.
[0003] Existing disinfectant bottles used for filling disinfectant solutions vary in diameter and height. However, most coding devices used in disinfectant production are only suitable for continuous automatic coding of bottles of the same size. They are not convenient for positioning bottles of different sizes so that they are aligned with the laser marking point, nor are they convenient for adjusting the height of the laser marking point to be flush with the coding position on the disinfectant bottle. Therefore, we propose a continuous automatic coding device and coding method for disinfectant production. Summary of the Invention
[0004] The purpose of this invention is to provide a continuous automatic coding device and coding method for disinfectant production, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A continuous automatic coding device for disinfectant production includes a base, a mounting frame connected to the base, and a conveyor body mounted on the mounting frame. Four sets of support rods are also mounted on the top of the base. Side baffles are connected to adjacent support rods on the left and right sides. The two sets of side baffles are located on the front and rear sides of the top of the conveyor body, respectively. Hinges are mounted on the inner sides of the two sets of side baffles. Movable plates for limiting disinfectant bottles are hinged to the two sets of hinges. A fixed box is connected to the top of the base through a support member. The two ends of the fixed box extend through the front and rear ends of the conveyor body. An adjustment mechanism for adjusting the distance between the two sets of movable plates is provided inside the fixed box. A height adjustment unit is provided on the upper rear side of the base. The height adjustment unit includes a fixed platform, which is connected to the outer wall of the rear side baffle. A vertical beam is installed on the fixed platform. A U-shaped moving frame is vertically slidably connected to the front end of the vertical beam. A photoelectric sensor is installed on the outer wall of the front end of the U-shaped moving frame. A telescopic marking component is provided on the outer right side of the U-shaped moving frame. The telescopic marking component includes a connecting box, which is connected to the U-shaped moving frame through a fixing component. A slidingly connected moving toothed plate is provided inside the connecting box, and a laser marking terminal is installed at the end of the moving toothed plate away from the vertical beam.
[0006] Preferably, the adjustment mechanism includes a servo motor located on the front outer wall of the fixed box, and the output end of the servo motor is connected to a bidirectional lead screw. The other end of the bidirectional lead screw is rotatably connected to the rear inner wall of the fixed box through a bearing. Two sets of threaded blocks are threadedly connected to the bidirectional lead screw. A crossbar is connected to the inner wall of the fixed box and directly above the bidirectional lead screw. Two sets of sliding parts are slidably connected to the crossbar. The bottom of the two sets of sliding parts is connected to the top of the two sets of threaded blocks respectively.
[0007] Preferably, the top of each of the two sets of sliding parts is connected to a connecting slider, and the top walls of the fixed box are provided with through slots that are adapted to the connecting sliders at both ends. The top of each of the two sets of connecting sliders is equipped with a push rod, and the other end of each of the two sets of push rods passes through a side baffle. Each of the two sets of side baffles is provided with a through hole that is adapted to the push rod. Each of the two sets of movable plates is equipped with two sets of fixed ear plates on the side near the push rod. Adjacent fixed ear plates are rotatably connected to a rotating shaft through a bearing. The end of the push rod away from the connecting slider is connected to the outer wall of the rotating shaft.
[0008] Preferably, the open end of the U-shaped moving frame is directly opposite the front outer wall of the vertical beam, and a geared motor is installed on the left outer wall of the U-shaped moving frame. The output end of the geared motor is connected to a drive rod, and the other end of the drive rod is rotatably connected to the right inner wall of the U-shaped moving frame through a bearing. A rotating gear is fitted on the drive rod, and multiple sets of meshing grooves are opened on the front end face of the vertical beam, and the meshing grooves are meshed with the rotating gears.
[0009] Preferably, the left side wall of the vertical beam has T-shaped grooves distributed vertically, a T-shaped block is slidably connected in the T-shaped groove, a linkage rod is installed on the outer wall of the T-shaped block, and the other end of the linkage rod is connected to the front outer wall of the U-shaped moving frame.
[0010] Preferably, a stepper motor is provided on the top of the connecting box, and a rotating rod is connected to the output end of the stepper motor. The bottom end of the rotating rod is rotatably connected to the bottom inner wall of the connecting box through a bearing. An adjusting gear is sleeved on the rotating rod, and the adjusting gear is meshed with the moving toothed plate. Through slots are provided on the front and rear side walls of the connecting box, and the through slots are slidably connected to the moving toothed plate.
[0011] Preferably, the bottom of the base is connected to a pad, and the lower surface of the pad is embedded with corrugated protrusions. The inner sides of both sets of movable plates are provided with rubber pads, and the rubber pads are connected to the movable plates by adhesive bonding.
[0012] S1: First, the diameter and height of the disinfectant bottle containing the disinfectant are detected. Then, the servo motor on the adjustment mechanism is controlled by the PLC controller. The operation of the servo motor can drive the bidirectional lead screw to rotate. After the two sets of threaded blocks connected to the bidirectional lead screw are limited by the sliding limit of the crossbar and the sliding part, the two sets of connecting sliders can slide in opposite or opposite directions in the through slot, thereby driving the two sets of push rods to move. Since the two sets of movable plates are hinged to the hinge seat and the push rods are connected to the outer wall of the rotating shaft, the two sets of push rods can adjust the distance between adjacent movable plates by moving in opposite or opposite directions until the distance between the ends of the adjacent movable plates away from the hinge seat is close to the diameter of the disinfectant bottle. S2: Then, the PLC controller controls the geared motor on the height adjustment unit to work. The operation of the geared motor can drive the rotating gear on the drive rod to rotate. Since the rotating gear is connected to multiple sets of meshing grooves, and the U-shaped moving frame is limited by the linkage rod, T-block and T-slot, the U-shaped moving frame can move vertically on the front end face of the vertical beam. This allows the height of the photoelectric sensor and the telescopic coding component to be adjusted until their heights are level with the coding position at the specified height on the disinfectant bottle. S3: Then, the stepper motor on the telescopic coding component is activated by the PLC controller. The operation of the stepper motor drives the adjustment gear fixedly connected to the rotating rod to rotate. Since the adjustment gear is meshed with the moving toothed plate, the moving toothed plate can slide back and forth in the connecting box until the laser coding position on the moving toothed plate is close to the coding position on the disinfectant bottle. S4: Finally, the conveyor belt feeds the disinfectant bottles from the left. As the bottles pass between adjacent movable plates, the spacing narrows until the bottles pass through. When the photoelectric sensor detects the bottle's position, it sends a signal to the external PLC controller. The PLC controller then stops the conveyor belt and initiates laser marking. The laser marking imprints the production date onto the bottle. After marking, the conveyor belt resumes operation, outputting the marked bottles from the right. The next set of bottles is then fed to the photoelectric sensor for detection. Once the sensor detects the signal, the conveyor belt stops, the laser marking completes, and the bottle is output from the right. This process continues, completing the continuous automatic marking of the disinfectant bottles.
[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention utilizes the operation of a servo motor on an adjusting mechanism to drive a bidirectional lead screw to rotate. Two sets of threaded blocks, threaded to the bidirectional lead screw, are limited by sliding contact between a crossbar and a sliding member. The two sets of connecting sliders can then slide in opposite or relative directions within the through-slot, thereby moving two sets of push rods. Since both sets of movable plates are hinged to the hinged seat, and the push rods are connected to the outer wall of the rotating shaft, the movement of the two sets of push rods in opposite or relative directions adjusts the distance between adjacent movable plates. The distance between adjacent movable plates can be narrowed to limit the movement of disinfectant bottles of different diameters. The operation of the reduction motor on the height adjustment unit drives the rotating gear on the drive rod to rotate. Because the rotating gear is connected to multiple meshing slots, and the U-shaped moving frame is connected... After the sliding limit of the moving rod, T-block, and T-slot, the U-shaped moving frame can move vertically on the front end of the vertical beam, thereby adjusting the height of the photoelectric sensor and the telescopic coding component. The photoelectric sensor can detect the position of the disinfectant bottle. When the disinfectant bottle reaches the set position, the photoelectric sensor sends a signal to the external PLC controller. The PLC controller controls the conveyor to stop working and the laser coding component to start working. The laser coding component can then code the production date on the disinfectant bottle. After coding is completed, the conveyor continues to work and outputs the coded disinfectant bottle from the right end. This process is repeated to complete the continuous automatic coding of disinfectant bottles. It is applicable to the continuous automatic coding of disinfectant bottles of different heights and diameters, with few limitations in application. Attached Figure Description

Detailed Implementation
[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0017] Example 1: Please see Figure 1-9This invention provides a technical solution: a continuous automatic coding device for disinfectant production, comprising a base 1, a mounting frame 2 connected to the base 1, and a conveyor body 3 mounted on the mounting frame 2. Four sets of support rods 4 are also mounted on the top of the base 1. Side baffles 5 are connected to adjacent support rods 4. The two sets of side baffles 5 are located on the front and rear sides of the top of the conveyor body 3, respectively. Hinge seats 7 are mounted on the inner sides of the two sets of side baffles 5. Movable plates 10 for limiting disinfectant bottles are hinged to the two sets of hinge seats 7. A fixing box 6 is connected to the top of the base 1 via a support member, and both ends of the fixing box 6 extend through the front and rear ends of the conveyor body 3. The fixing box 6 contains an adjustment mechanism for adjusting the distance between the two sets of movable plates 10. The bottoms of the four sets of support rods 4 are all connected to the base. 1. Fixed connection: The other end of the support rod 4 is fixedly connected to the side baffle 5. The side baffle 5, supported by the support rod 4, is placed at both ends of the top of the conveyor body 3. The bottom of the side baffle 5 is left with a certain gap from the top of the conveyor body 3, so as not to affect the normal conveying of the conveyor body 3. Before use, the electrical terminals of each electrical device are electrically connected to the external power supply and the electrical terminals of the PLC controller (installed on the outer wall of the front side baffle 5) through wires. Then, the diameter and height of the disinfectant bottle for filling disinfectant are measured. Through the action of the adjustment mechanism, the two sets of hinged movable plates 10 can be moved in opposite or opposite directions. The distance between adjacent movable plates 10 can be adjusted, and the distance between adjacent movable plates 10 can be narrowed from wide to narrow, which can limit the disinfectant bottles of different diameters. A height adjustment unit 8 is provided on the upper rear side of the base 1. The height adjustment unit 8 includes a fixed platform 800, which is connected to the outer wall of the rear side baffle 5. A vertical beam 801 is installed on the fixed platform 800. A U-shaped moving frame 803 is vertically slidably connected to the front end of the vertical beam 801. A photoelectric sensor 805 is installed on the front outer wall of the U-shaped moving frame 803. A telescopic marking component 9 is provided on the right outer wall of the U-shaped moving frame 803. The telescopic marking component 9 includes a connecting box 901, which is connected to the U-shaped moving frame 803 by a fixing component. A slidingly connected moving toothed plate 903 is provided inside the connecting box 901. A laser marking terminal 904 is installed at the end of the moving toothed plate 903 away from the vertical beam 801. The laser marking terminal 904 is existing equipment capable of printing QR codes related to production dates or information onto disinfectant bottles. Its specific working principle will not be elaborated here. The U-shaped moving frame 803 of the height adjustment unit 8 can move vertically at the front end of the vertical beam 801, thereby adjusting the height of the photoelectric sensor 805 and the telescopic marking component 9 until their heights are aligned with the marking position on the disinfectant bottle. The moving toothed plate 903 on the telescopic marking component 9 can move back and forth within the connecting box 901. The movement of the moving toothed plate 903 drives the laser marking terminal 904 to move until it is aligned with the marking position on the disinfectant bottle. Simply place the bottle near the disinfectant bottle. The photoelectric sensor 805 can detect the position of the disinfectant bottle. When the disinfectant bottle reaches the set position, the photoelectric sensor 805 sends a signal to the external PLC controller. The PLC controller controls the conveyor body 3 to stop working and the laser marking tool 904 to work. The laser marking tool 904 can then mark the production date on the disinfectant bottle. After marking is completed, the conveyor body 3 continues to work and outputs the marked disinfectant bottle from the right end. This process is repeated to complete the continuous automatic marking of disinfectant bottles. It is applicable to the continuous automatic marking of disinfectant bottles of different heights and diameters, and has few limitations in use.
[0018] The adjustment mechanism includes a servo motor 17, which is located on the front outer wall of the fixed box 6. The output end of the servo motor 17 is connected to a bidirectional lead screw 18. The other end of the bidirectional lead screw 18 is rotatably connected to the rear inner wall of the fixed box 6 via a bearing. Two sets of threaded blocks 19 are threaded onto the bidirectional lead screw 18. A crossbar 20 is connected to the inner wall of the fixed box 6, directly above the bidirectional lead screw 18. Two sets of sliding members 21 are slidably connected to the crossbar 20. The bottoms of the two sets of sliding members 21 are respectively connected to the two sets of threaded blocks 19. The top connection is provided; two sets of threaded blocks 19 are fixedly connected to two sets of sliding parts 21 respectively. The fixed box 6 is fixedly installed on the base 1 by two sets of support parts, and the top and bottom of the fixed box 6 are left with gaps between them and the conveyor body 3, so as not to affect the normal operation of the conveyor body 3. The operation of the servo motor 17 can drive the bidirectional lead screw 18 to rotate forward or reverse. After the two sets of threaded blocks 19 connected to the bidirectional lead screw 18 are limited by the sliding of the crossbar 20 and the sliding parts 21, the two sets of sliding parts 21 can move in opposite or opposite directions.
[0019] Both sets of sliding parts 21 are connected to the top of a connecting slider 16. The top walls of the fixed box 6 have through slots 15 at both ends that fit the connecting slider 16. Both sets of connecting sliders 16 have push rods 14 mounted on their tops. The other ends of both push rods 14 pass through side baffles 5. Both side baffles 5 have through holes 13 that fit the push rods 14. Two sets of fixed ear plates 11 are mounted on the side of each of the two movable plates 10 closest to the push rods 14. Adjacent fixed ear plates 11 are rotatably connected to a rotating shaft 12 via bearings. The end of the push rod 14 away from the connecting slider 16 is connected to the outer wall of the rotating shaft 12. Both ends of the connecting slider 16 are fixedly connected to the push rod 14 and the sliding part 21, respectively. The fixed ear plates 11 are fixedly mounted... Mounted on the outer side of the movable plate 10, the hinge seat 7 is fixedly connected to the side baffle 5. The movement of the two sets of sliding parts 21 drives the two sets of connecting sliders 16 to move in opposite or opposite directions within the through slot 15, which in turn drives the two sets of pushing rods 14 to move in opposite or opposite directions. Since the movable plate 10 and the hinge seat 7 are hinged, and the pushing rods 14 are fixedly connected to the outer wall of the rotating shaft 12, adjacent movable plates 10 can rotate along the direction of the hinge seat 7, thereby adjusting the distance between adjacent movable plates 10. The distance between adjacent movable plates 10 changes from wide to narrow. As the conveyor body 3 works, the narrowing distance limits the position of the disinfectant bottles, ensuring that the lateral position of each set of disinfectant bottles is on the same horizontal line, thus ensuring the continuity of coding.
[0020] The open end of the U-shaped moving frame 803 faces the front outer wall of the vertical beam 801. A reduction motor 804 is installed on the left outer wall of the U-shaped moving frame 803. The output end of the reduction motor 804 is connected to a drive rod, and the other end of the drive rod is rotatably connected to the right inner wall of the U-shaped moving frame 803 through a bearing. A rotating gear 809 is fitted on the drive rod. Multiple sets of meshing grooves 802 are opened on the front face of the vertical beam 801, and the meshing grooves 802 are meshed with the rotating gear 809. The operation of the reduction motor 804 can drive the rotating gear 809 on the drive rod to rotate. Since the rotating gear 809 is meshed with the multiple sets of meshing grooves 802, and the U-shaped moving frame 803 is limited by the sliding of the linkage rod 808, the T-block 807 and the T-slot 806, the U-shaped moving frame 803 can move vertically on the front face of the vertical beam 801.
[0021] The left side wall of the vertical beam 801 has vertically distributed T-shaped grooves 806. A T-shaped block 807 is slidably connected in the T-shaped groove 806. A linkage rod 808 is installed on the outer wall of the T-shaped block 807, and the other end of the linkage rod 808 is connected to the front outer wall of the U-shaped moving frame 803. The linkage rod 808 is fixedly connected to the T-shaped block 807 and the left outer wall of the U-shaped moving frame 803. Through the sliding limit of the T-shaped block 807 and the T-shaped groove 806, the U-shaped moving frame 803 can be prevented from detaching from the front end of the vertical beam 801 when sliding vertically. The reduction motor 804 itself has a self-locking function. When the reduction motor 804 is not working, the rotating gear 809 does not rotate, and the U-shaped moving frame 803 can be stably placed at the front end of the vertical beam 801.
[0022] A stepper motor 902 is provided on the top of the connecting box 901, and a rotating rod is connected to the output end of the stepper motor 902. The bottom end of the rotating rod is rotatably connected to the inner wall of the bottom end of the connecting box 901 through a bearing. An adjusting gear 905 is sleeved on the rotating rod, and the adjusting gear 905 is meshed with the moving gear plate 903. Through slots are provided on the front and rear side walls of the connecting box 901, and the through slots are slidably connected with the moving gear plate 903. The side of the moving gear plate 903 near the adjusting gear 905 has multiple sets of tooth grooves that are adapted to the adjusting gear 905. The operation of the stepper motor 902 can drive the adjusting gear 905 on the rotating rod to rotate forward or backward. Since the adjusting gear 905 is meshed with the tooth grooves on the moving gear plate 903, the moving gear plate 903 can drive the fixedly connected laser cutting dock 904 to move back and forth, ensuring that the laser cutting dock 904 is close to the disinfectant bottle.
[0023] Example 2: Reference Figure 1 and Figure 2 This embodiment differs from the first embodiment in that: a pad is connected to the bottom of the base 1, and the lower surface of the pad is embedded with corrugated protrusions. Rubber pads are provided on the inner sides of both sets of movable plates 10, and the rubber pads are connected to the movable plates 10 by adhesive bonding. The pad and the corrugated protrusions increase the friction between the base 1 and the workbench, improving the stability of the entire coding device during operation. The rubber pads play a role in increasing friction, ensuring the normal delivery of disinfectant bottles. The adhesive rubber pads can be easily removed for easy replacement later.
[0024] A continuous automatic coding device and coding method for disinfectant production includes the following steps. S1: First, connect the electrical terminals of each electrical device to the external power supply and the electrical terminals of the PLC controller (installed on the outer wall of the front side baffle 5) through wires to detect the diameter and height of the disinfectant bottle. Then, control the servo motor 17 on the adjustment mechanism through the PLC controller. The operation of the servo motor 17 can drive the bidirectional lead screw 18 to rotate. After the two sets of threaded blocks 19 connected to the bidirectional lead screw 18 are limited by the sliding limit of the crossbar 20 and the sliding member 21, the two sets of connecting sliders 16 can slide in opposite or opposite directions in the through slot 15, thereby driving the two sets of pushing rods 14 to move. Since the two sets of movable plates 10 are hinged to the hinge seat 7 and the pushing rods 14 are connected to the outer wall of the rotating shaft 12, the two sets of pushing rods 14 can adjust the distance between adjacent movable plates 10 by moving in opposite or opposite directions until the distance between the ends of the adjacent movable plates 10 away from the hinge seat 7 is close to the diameter of the disinfectant bottle. S2: Then, the PLC controller controls the geared motor 804 on the height adjustment unit 8 to work. The operation of the geared motor 804 can drive the rotating gear 809 on the drive rod to rotate. Since the rotating gear 809 is meshed with multiple sets of meshing grooves 802, and the U-shaped moving frame 803 is limited by the linkage rod 808, the T-block 807 and the T-slot 806, the U-shaped moving frame 803 can move vertically on the front end face of the vertical beam 801, so that the height of the photoelectric sensor 805 and the telescopic coding component 9 can be adjusted until the height of both is level with the coding position at the specified height on the disinfectant bottle. S3: Then, the stepper motor 902 on the telescopic coding component 9 is activated by the PLC controller. The operation of the stepper motor 902 drives the adjusting gear 905 fixedly connected on the rotating rod to rotate. Since the adjusting gear 905 is meshed with the moving toothed plate 903, the moving toothed plate 903 can slide back and forth in the connecting box 901 until the laser marking terminal 904 on the moving toothed plate 903 is close to the coding position on the disinfectant bottle. S4: Finally, the conveyor body 3 inputs the disinfectant bottle from the left end. As the disinfectant bottle passes between adjacent movable plates 10, the spacing narrows until the bottle passes the adjacent movable plates 10. When the photoelectric sensor 805 detects the position of the disinfectant bottle, it sends a signal to the external PLC controller. The PLC controller stops the conveyor body 3 and activates the laser marking tool 904. The laser marking tool 904 marks the production date on the disinfectant bottle. After marking, the conveyor body 3 continues to output the marked disinfectant bottle from the right end. The next set of disinfectant bottles is then conveyed to the front end of the photoelectric sensor 805 for detection. After the signal is detected, the conveyor body 3 stops, and the laser marking tool 904 completes the marking. The conveyor body 3 then outputs the disinfectant bottle from the right end, and so on, to complete the continuous automatic marking of the disinfectant bottles.

An adjusting gear (905) is sleeved on the rotating rod, and the adjusting gear (905) is meshed with a moving toothed plate (903). The front and rear side walls of the connecting box (901) are provided with through slots, and the through slots are slidably connected to the moving toothed plate (903).
9. A continuous automatic coding device for disinfectant production according to claim 1, characterized in that: The bottom of the base (1) is connected to a pad, and the lower surface of the pad is embedded with a corrugated protrusion. The inner sides of the two sets of movable plates (10) are provided with rubber pads, and the rubber pads are connected to the movable plates (10) by adhesive bonding.
10. The coding method of a continuous automatic coding device for disinfectant production according to any one of claims 1-9, characterized in that: The method includes the following steps: S1: First, the diameter and height of the disinfectant bottle containing the disinfectant are detected. Then, the servo motor (17) on the adjustment mechanism is controlled by the PLC controller. The operation of the servo motor (17) can drive the bidirectional lead screw (18) to rotate. After the two sets of threaded blocks (19) connected to the bidirectional lead screw (18) are limited by the sliding limit of the crossbar (20) and the sliding part (21), the two sets of connecting sliders (16) can slide in opposite or opposite directions in the through slot (15), thereby driving the two sets of push rods (14) to move. Since the two sets of movable plates (10) are hinged to the hinge seat (7) and the push rods (14) are connected to the outer wall of the rotating shaft (12), the two sets of push rods (14) can adjust the distance between the adjacent movable plates (10) by moving in opposite or opposite directions until the distance between the end of the adjacent movable plates (10) away from the hinge seat (7) is close to the diameter of the disinfectant bottle. S2: Then, the PLC controller controls the geared motor (804) on the height adjustment unit (8) to work. The operation of the geared motor (804) can drive the rotating gear (809) on the drive rod to rotate. Since the rotating gear (809) is meshed with multiple sets of meshing grooves (802), and the U-shaped moving frame (803) is limited by the linkage rod (808), T-block (807) and T-slot (806), the U-shaped moving frame (803) can move vertically on the front end face of the vertical beam (801). The height of the photoelectric sensor (805) and the telescopic coding component (9) can be adjusted until the height of both is level with the coding position at the specified height on the disinfectant bottle. S3: Then, the stepper motor (902) on the telescopic coding component (9) is activated by the PLC controller. The operation of the stepper motor (902) drives the adjustment gear (905) fixedly connected on the rotating rod to rotate. Since the adjustment gear (905) is meshed with the moving toothed plate (903), the moving toothed plate (903) can slide back and forth in the connecting box (901) until the laser marking point (904) on the moving toothed plate (903) is close to the coding position on the disinfectant bottle. S4: Finally, the conveyor (3) inputs the disinfectant bottle from the left end. When the disinfectant bottle passes between adjacent movable plates (10), the distance between them narrows until the disinfectant bottle passes the adjacent movable plates (10). When the photoelectric sensor (805) detects the position of the disinfectant bottle, the photoelectric sensor (805) sends a signal to the external PLC controller. The PLC controller controls the conveyor (3) to stop working and the laser marking plate (904) to work. The laser marking plate (904) can mark the production date on the disinfectant bottle. After marking is completed, the conveyor (3) continues to work and outputs the marked disinfectant bottle from the right end. At this time, the next set of disinfectant bottles can be conveyed to the front end of the photoelectric sensor (805) for detection. After the signal is detected, the conveyor (3) stops working and the laser marking plate (904) completes the marking. After marking, the conveyor (3) outputs the disinfectant bottle from the right end. This process is repeated to complete the continuous automatic marking of the disinfectant bottle.
