Description

Technical Field

[0001] This utility model relates to the field of spraying technology, and in particular to a QR code spraying device. Background Technology

[0002] With the rapid development of information technology, QR codes, as an efficient and convenient way of storing and transmitting information, have been widely used in many fields such as logistics, warehousing, and manufacturing. During the manufacturing and processing of products, it is often necessary to use spraying equipment to spray QR codes on the product surface.

[0003] A Chinese patent with publication number CN216033283U discloses a QR code spraying device for tinplate, comprising two support plates and a processing panel fixedly connected between the tops of the two support plates. A feeding box containing stacked tinplate sheets is fixedly connected to the processing panel. The bottom of the feeding box has a left opening and a right opening. A pushing mechanism is installed on the processing panel outside the left opening, which enters the feeding box through the left opening and pushes out the bottom layer of tinplate sheets through the right opening. A through-hole is provided on the processing panel outside the right opening, and a fixing mechanism for securing the tinplate sheets is installed inside the through-hole. A bracket is installed above the through-hole, and a spraying mechanism for spraying the tinplate sheets is installed on the bracket. This device facilitates automatic feeding, accurate spraying, and automatic drying before delivery after spraying.

[0004] In the current technology, when multiple tinplate sheets are fed from the bottom of the material box, the stacked tinplate sheets are relatively heavy, resulting in greater friction during the pushing process. This can easily cause scratches on the surface of the tinplate sheets, affecting their appearance. Furthermore, during the pushing process, the bottom tinplate sheet will fall onto the output end of the cylinder under the influence of gravity. When the push plate retracts, it is easy for it to jam with the tinplate sheet above it, affecting the continued feeding.

[0005] Therefore, a QR code spraying device is proposed to address the above problems. Utility Model Content

[0006] Therefore, the technical problem to be solved by this utility model is to overcome the inconvenience of feeding materials in the prior art.

[0007] To solve the above-mentioned technical problems, this utility model provides a QR code spraying device.

[0008] In one embodiment of this utility model, a storage box is included, and a feeding mechanism is provided inside the storage box. The feeding mechanism includes two reciprocating screws rotatably connected to the storage box via bearings. A lifting plate is threaded onto the two reciprocating screws. Vertical rods are fixed to the four corners of the storage box, and the four corners of the lifting plate are slidably connected to the vertical rods. The bottom of each reciprocating screw penetrates the storage box, and a wheel is fixed to the bottom end of each reciprocating screw. A belt is sleeved between the two wheels. An L-shaped plate is fixed to the bottom of the storage box, and a motor is fixed to the top of the L-shaped plate. The output shaft of the motor is fixed to the bottom of the reciprocating screw. A side plate is fixed to the side wall of the storage box, and an electric push rod is fixed to the top of the side plate. A push plate is fixed to the output end of the electric push rod.

[0009] In one embodiment of this utility model, a conveyor is provided on the side of the storage box away from the electric push rod, and the top of the conveyor is flush with the bottom of the push plate and the top of the storage box; a limit block, a spraying equipment body, a heating box and an infrared sensor are sequentially provided on the conveyor.

[0010] In one embodiment of this utility model, two mounting plates are symmetrically fixed to the top of the conveyor, and a bidirectional ball screw is rotatably connected between the two mounting plates via bearings. Two movable plates are threaded onto the bidirectional ball screw, and a limit block is fixed to the bottom of each movable plate. Multiple rollers are rotatably connected to the inner wall of each limit block. Each limit block is a trapezoidal block with its inclined side located on the side closer to the storage box. A rotating block is provided at one end of the bidirectional ball screw.

[0011] In one embodiment of the present invention, four fixed plates are fixedly connected to the top of the conveyor, and guide rails are fixedly connected between two adjacent fixed plates. Sliding seats are slidably connected to the guide rails. The main body of the spraying equipment is installed at the bottom of the sliding seat near the limiting block, and a distance sensor is installed on the side wall. The distance sensor is directly opposite the center of the fixed plate.

[0012] In one embodiment of this utility model, an infrared sensor is installed at the bottom of the sliding seat away from the limiting block; the infrared sensor is electrically connected to the conveyor.

[0013] In one embodiment of this utility model, each sliding seat is threaded with a fastening bolt, and each fastening bolt is fixed with a wing nut.

[0015] In one embodiment of this utility model, two guide rods are fixedly connected between the two mounting plates, and the movable plates slide on the guide rods.

[0016] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0017] The QR code spraying device described in this utility model is equipped with a reciprocating screw, a rotating wheel, and a belt. Through the cooperation of the rotating wheel and the belt, the two reciprocating screws rotate synchronously, driving the lifting plate to move upward. The lifting plate drives the material upward, and when the top material is just aligned with the top of the storage box, the movement stops, and the electric push rod is activated. The electric push rod drives the push plate through its output end, pushing the top material to the conveyor on one side, thus completing the feeding and achieving the function of rapid feeding.

[0018] The QR code spraying device described in this utility model is equipped with a bidirectional ball screw, a limiting block, and a roller. By rotating the rotating block, the bidirectional ball screw is driven to rotate, which in turn drives a moving plate to move in the opposite direction.

The material passes through the roller during conveying, which facilitates the limiting and conveying of the material. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0028] Reference Figures 1-6 As shown, a QR code spraying device of this utility model includes a storage box 1, which is equipped with a feeding mechanism. The feeding mechanism includes two reciprocating screws 7 rotatably connected to the storage box 1 via bearings. Lifting plates 6 are threadedly connected to the two reciprocating screws 7. Vertical rods 8 are fixed to the four corners of the storage box 1, and the four corners of the lifting plates 6 are slidably connected to the vertical rods 8 respectively. The bottom of each reciprocating screw 7 passes through the storage box 1, and a rotating wheel 2 is fixed to the bottom end of each reciprocating screw 7. A belt 3 is sleeved between the two rotating wheels 2. An L-shaped plate 5 is fixed to the bottom of the storage box 1, and a motor 4 is fixed to the top of the L-shaped plate 5. The output shaft of the motor 4 is fixed to the bottom of the reciprocating screw 7. A side plate 9 is fixed to the side wall of the storage box 1, and an electric push rod 10 is fixed to the top of the side plate 9. A push plate 11 is fixed to the output end of the electric push rod 10.

[0029] In existing technology, during material feeding, the stacked materials are heavy, resulting in significant friction during pushing, which can easily cause surface scratches and affect the appearance. Furthermore, during the pushing process, the bottommost material falls under gravity and can jam the pushing mechanism, affecting continued feeding. In operation, the material is placed on the lifting plate 6 of the storage box 1. The motor 4 is activated, and its output shaft drives the reciprocating screw 7 to rotate. This rotation of the reciprocating screw 7 drives the connected reciprocating screw 7 to rotate, which in turn drives the connected rotating wheel 2 to rotate. The belt 3 drives another wheel 2 to rotate, which in turn drives another reciprocating screw 7 connected to the wheel 2 to rotate. Through the synchronous rotation of the two reciprocating screws 7, the lifting plate 6 is driven to move upward. During the movement, the lifting plate 6 drives the material upward. When the uppermost material is just aligned with the top of the storage box 1, the movement stops and the electric push rod 10 is started. The electric push rod 10 drives the push plate 11 to move through the output end. The push plate 11 pushes the uppermost material to the conveyor 12 on one side, thus completing the feeding.

[0030] Furthermore, such as Figure 1 and Figure 4 As shown, a conveyor 12 is provided on the side of the storage box 1 away from the electric push rod 10. The top of the conveyor 12 is flush with the bottom of the push plate 11 and the top of the storage box 1. A limit block 25, a spraying equipment body 19, a heating box 22 and an infrared sensor 20 are sequentially provided on the conveyor 12.

[0031] During operation, the conveyor 12 facilitates the transport of materials. The materials pass sequentially through the limit block 25, the main body of the spraying equipment 19, the heating box 22, and the infrared sensor 20. The limit block 25 helps to limit materials of different sizes in the middle of the conveyor 12. The main body of the spraying equipment 19 is used to spray QR codes. The heating box 22 is used to quickly dry the QR codes. The infrared sensor 20 is used to detect whether the QR codes are correct. If they are correct, they are sent to the next process. If there is a problem, the conveyor 12 needs to be stopped and the staff needs to be alerted to check.

[0032] Furthermore, such as Figure 6 As shown, two mounting plates 27 are symmetrically fixed to the top of the conveyor 12. A bidirectional ball screw 28 is rotatably connected between the two mounting plates 27 via bearings. Two movable plates 30 are threaded onto the bidirectional ball screw 28. Limiting blocks 25 are fixed to the bottom of each movable plate 30. Multiple rollers 26 are rotatably connected to the inner wall of each limiting block 25. Each limiting block 25 is a trapezoidal block with its inclined side located on the side closest to the storage box 1. A rotating block 31 is provided at one end of the bidirectional ball screw 28.

[0033] When it is necessary to limit the material during operation, the rotating block 31 is rotated, which drives the bidirectional ball screw 28 to rotate. The bidirectional ball screw 28 drives the moving plate 30 to move in the opposite direction, and the moving plate 30 drives the limiting block 25 to move in the opposite direction until it matches the size of the material, at which point the movement stops. The material passes through the roller 26 during conveying, which facilitates the limiting and conveying of the material.

[0034] Furthermore, such as Figure 4 As shown, four fixed plates 13 are fixed to the top of the conveyor 12, and guide rails 14 are fixed between two adjacent fixed plates 13. Sliding seats 21 are slidably connected to each guide rail 14. The bottom of the sliding seat 21 near the limiting block 25 is equipped with the main body 19 of the spraying equipment, and a distance sensor 18 is installed on the side wall. The distance sensor 18 is directly opposite the center of the fixed plate 13.

[0035] During operation, the guide rail 14 and sliding seat 21 facilitate the movement of the spraying equipment body 19 for spraying materials at different locations. The distance sensor 18 facilitates the control of the specific position of the spraying equipment body 19, thereby improving the accuracy of the nozzle.

[0036] Furthermore, such as Figure 5 As shown, an infrared sensor 20 is installed at the bottom of the sliding seat 21, which is away from the limiting block 25; the infrared sensor 20 is electrically connected to the conveyor 12.

[0037] During operation, an infrared sensor 20 is set up to detect whether the QR code is correct and whether the QR code color is light. If an abnormality is detected, the conveyor 12 should be stopped in real time and the staff should be reminded to check.

[0038] Furthermore, such as Figure 4 As shown, each sliding seat 21 is threaded with a fastening bolt 16, and each fastening bolt 16 is fixed with a wing nut 17.

[0039] During operation, the position of the sliding seat 21 is easily fixed by setting the fastening bolt 16 and the wing nut 17, preventing the position from shifting during operation.

[0040] Furthermore, such as Figure 5 As shown, a connecting plate 15 is fixed between the two sliding seats 21, a heating box 22 is fixed to the bottom of the connecting plate 15, a plurality of heating wires 23 are fixed to the bottom of the heating box 22, and two fans 24 are provided inside the heating box 22.

[0041] During operation, when the coated material passes through the heating box 22, the heating wire 23 generates heat by energizing the heating wire 23 and the fan 24, and the fan 24 blows the heat onto the material, causing the QR code to dry quickly.

[0042] Furthermore, such as Figure 6 As shown, two guide rods 29 are fixed between the two mounting plates 27, and the movable plates 30 slide on the guide rods 29.

[0043] During operation, the movable plate 30 slides on the guide rod 29, which limits the movable plate 30 to slide in the horizontal direction.

[0044] Working principle: The material is placed on the lifting plate 6 of the storage box 1. The motor 4 is turned on, and the output shaft of the motor 4 drives the reciprocating screw 7 to rotate. During the rotation of the reciprocating screw 7, the connected reciprocating screw 7 is also rotated. The connected rotating wheel 2 is driven to rotate through the belt 3. The rotating wheel 2 drives another rotating wheel 2 to rotate, which in turn drives another reciprocating screw 7 connected to the rotating wheel 2 to rotate. Through the synchronous rotation of the two reciprocating screws 7, the lifting plate 6 is driven to move upward. During the movement, the lifting plate 6 drives the material upward. When the top material is just aligned with the top of the storage box 1, the movement stops, and the electric push rod 10 is started. The electric push rod 10 drives the push plate 11 to move through the output end. The push plate 11 pushes the top material to the conveyor 12 on one side, thus completing the feeding.

[0045] When it is necessary to limit the material, the rotating block 31 is rotated, which drives the bidirectional ball screw 28 to rotate. The bidirectional ball screw 28 drives the moving plate 30 to move in the opposite direction. The moving plate 30 drives the limiting block 25 to move in the opposite direction until it matches the size of the material, at which point the movement stops. The material passes through the roller 26 during conveying, which facilitates the limiting and conveying of the material.

[0046] The guide rail 14 and sliding seat 21 facilitate the movement of the spraying equipment body 19 for spraying materials at different locations. The distance sensor 18 facilitates the control of the specific position of the spraying equipment body 19, improving the accuracy of the spray nozzle. When the sprayed material passes through the heating box 22, the heating wire 23 generates heat, and the fan 24 blows the heat onto the material, allowing the QR code to dry quickly. The infrared sensor 20 facilitates the detection of the correctness of the QR code and whether the QR code color is light. If an abnormality is detected, the conveyor 12 must be stopped in real time, and the staff must be alerted to check.

[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
