Description

Technical Field

[0001] This utility model relates to the field of cardboard box proofing technology, and in particular to a high-efficiency cardboard box proofing and printing device. Background Technology

[0002] A carton sample making machine is a piece of machinery used by carton factories to produce carton samples. Generally, after receiving a customer's commission and understanding the customer's specifications and requirements for the product, the carton factory will first produce one or more samples and return them to the customer for modification and confirmation.

[0003] A search revealed a Chinese patent publication number CN220576728U, which discloses a carton printing proofing device. The device includes two symmetrical support plates, a belt conveyor between the two support plates, a guide device between the front ends of the two support plates, and multiple housings rotatably connected to the support plates. A driving device is provided at one end of the housing located outside the two support plates, and a pressing unit is provided at one end of the housing located between the two support plates. The pressing unit includes multiple pressure rods evenly distributed around the circumference and fixed to the end of the housing located between the two support plates. An air jet unit is provided on the housing, and a sliding seat is provided above the support plates. A processing tool is provided on the sliding seat.

[0004] This patent uses guide rods to limit the left and right positions of the carton. During transport, pressure rods roll downwards and gradually contact the carton. As the pressure rods bend and deform, they gradually press the carton, fixing the contact area between the carton and the belt conveyor. As the carton moves backward, more pressure rods press it down without affecting its backward movement, achieving precise carton transport. However, the guide rods are fixed in position, and cartons come in various sizes. When the carton size is smaller than the distance between the two guide rods, the guide rods have difficulty positioning the carton. When the carton size is much larger than the distance between the two guide rods, the guide rods cover a large area of ​​the top of the carton, which may interfere with sampling.

[0027] Example 1

[0028] A high-efficiency proofing and printing device for cardboard boxes, such as Figures 1 to 3As shown, the device includes a fixed frame 1. A conveyor belt 2 is installed on the top outer wall of the fixed frame 1. The conveyor belt 2 is a mature existing technology, so it will not be described in detail here. Two parallel guide frames 3 are fixedly connected to both ends of the top outer wall of the fixed frame 1. A connecting plate 4 is slidably connected to both ends of the guide frame 3. The same end of the two guide frames 3 is slidably connected to the same connecting plate 4. A guide assembly 5 is connected to the bottom outer wall of the connecting plate 4. A through hole is opened on the top outer wall of the guide frame 3. A bolt 6 is threadedly connected to the top outer wall of the connecting plate 4. A washer 7 is sleeved on the side wall of the bolt 6. The washer 7 is pressed and fixed to the top outer wall of the guide frame 3.

[0029] The guide assembly 5 includes a fixed block 8 and multiple arc-shaped plates 9. The fixed block 8 is rotatably connected to the bottom outer wall of the connecting plate 4. The multiple arc-shaped plates 9 are all disposed on the side wall of the fixed block 8 and are axially arranged around the axis of the fixed block 8. The side wall of the fixed block 8 has a sliding cavity 10 corresponding to the arc-shaped plate 9. A connecting rod 11 is slidably connected to the inner wall of the sliding cavity 10. One end of the connecting rod 11 is connected to the arc-shaped plate 9, and the other end of the connecting rod 11 is connected to the inner wall of the sliding cavity 10 through a spring 12.

[0030] The top outer wall of the fixed frame 1 is connected to the movable frame 13 via a linear drive mechanism. The top outer wall of the movable frame 13 is connected to the movable block 14 via a linear active mechanism. The movement directions of the two linear drive mechanisms are perpendicular to each other. The linear drive mechanism is a mature existing technology, and its basic structure and working principle are well known to those skilled in the art, so it will not be described in detail here. The bottom outer wall of the movable block 14 is connected to the mounting frame 15. The side wall of the mounting frame 15 is equipped with a prototyping unit. The prototyping unit includes a vibrating cutter head, a flat cutter head, a crimping wheel, a small cutter head, and a pen tip, which can be replaced as needed. This is a mature existing technology, so it will not be described in detail here.

[0031] During operation, rotating bolt 6 removes the pressure of washer 7, allowing adjustment of the distance between the two connecting plates 4 to guide the carton to be sampled. After adjustment, reverse bolt 6, pressing the connecting plate 4 through washer 7. Then, place the carton on one end of conveyor belt 2, which transports the carton. The arc plate 9 contacts the side wall of the carton, and the friction between the carton and the arc plate 9 causes the fixing block 8 to rotate, causing multiple arc plates 9 on the side wall of the fixing block 8 to contact the side wall of the carton in sequence, guiding the carton. The limiting structure at one end of the fixing frame 1 blocks the carton after it reaches the predetermined position, and the conveyor belt 2 closes. The linear drive mechanism drives the moving frame 13 and the moving block 14 to move, changing the position of the sampling unit for sampling.

[0032] By setting up a guide frame 3, a connecting plate 4, a bolt 6, and a washer 7, the distance between the two connecting plates 4 can be adjusted according to the specifications of the carton, so that multiple guide components 5 can contact the side walls of cartons of different specifications to guide the carton.

[0033] By placing the guide component 5 on the side wall of the carton, the guide component 5 will not obstruct the upper surface of the carton when guiding the carton, thus not hindering the movement of the proofing unit and making the proofing area on the top of the carton larger.

[0034] Example 2

[0035] A high-efficiency proofing and printing device for cardboard boxes is provided in this embodiment, which is based on embodiment 1 and makes the following improvements, such as... Figure 1 , Figure 4 As shown, a connecting frame 16 is fixedly connected to the side wall of the mounting frame 15. The connecting frame 16 is L-shaped, and a dust suction head 17 is connected to one end of the connecting frame 16. The opening of the dust suction head 17 faces the contact point between the sampling unit and the carton. A collection box 19 is fixed to the bottom outer wall of the fixed frame 1. A fan is installed on one side of the outer wall of the collection box 19, and a barrier net is installed on the inner wall of the collection box 19. One end of the collection box 19 is connected to the dust suction head 17 through a connecting pipe 18.

[0036] During the prototyping process, the fan creates a negative pressure inside the collection box 19, and the debris generated during prototyping is sucked into the collection box 19 through the connecting pipe 18 and the dust suction head 17. The debris is then trapped and collected in the collection box 19 by the barrier net.

[0037] By incorporating a mounting bracket 15, a connecting bracket 16, a dust extraction head 17, a connecting pipe 18, and a collection box 19, debris generated during the prototyping process can be extracted and collected, preventing debris from escaping into the environment.

[0038] Working principle: During operation, rotating bolt 6 removes the pressure of washer 7, allowing adjustment of the distance between the two connecting plates 4 to guide the carton to be sampled. After adjustment, reverse bolt 6, which then presses the connecting plate 4 through washer 7. The carton is then placed on one end of conveyor belt 2, which transports it. The arc plate 9 contacts the side wall of the carton, and the friction between the carton and the arc plate 9 causes the fixing block 8 to rotate, causing multiple arc plates 9 on the side wall of the fixing block 8 to contact the side wall of the carton in sequence, thus guiding the carton. The limiting structure at one end of the fixing frame 1 blocks the carton after it reaches the predetermined position, and the conveyor belt 2 closes. The linear drive mechanism drives the moving frame 13 and the moving block 14 to move, changing the position of the sampling unit for sampling. Simultaneously, the fan creates negative pressure inside the collection box 19, drawing debris generated during sampling into the collection box 19 through the connecting pipe 18 and the dust suction head 17. The debris is then collected in the collection box 19 by the barrier net.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
