Description

Technical Field

[0001] This utility model relates to the field of paper box punching technology, specifically to a punching device for paper box printing and packaging. Background Technology

[0002] Cardboard boxes are a common packaging method, mainly used for the transportation and sale of goods. Cardboard box packaging is characterized by easy availability of materials, light weight, and low cost, and is widely used in the packaging of various products such as food, medicine, and electronics. At the same time, cardboard boxes can be printed with various patterns and designs to enhance the product's aesthetics.

[0003] During the printing of packaging boxes, some boxes need to be punched to facilitate ventilation, threading of ropes, or locking. However, different batches of boxes have different sizes and punching positions. Boxes in the same batch need to be punched in the same position. When punching directly with a hole punch, it is difficult to quickly find the required punching point, which will cause deviations in the position of multiple punches. The accuracy of the boxes is insufficient, which affects the quality of the packaging. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a punching device for paper box printing and packaging, which can center and position the paper box and determine the position of the punching surface, and then punch holes at the determined points by a puncher.

[0009] The perforated surface defines the structure and is set on the positioning seat. The perforated surface of the cardboard box is arranged in the perforation clamp through the perforated surface defining the structure.

[0010] Top plate and press-locking structure; the top plate is mounted on the base by a spring, and a press-locking structure is provided between the top plate and the base.

[0011] As an improvement, the centering clamping structure includes a slider, a connecting rod, and a clamping plate; a support rod is formed on the top of the positioning seat, and the clamping plate is vertically arranged and fixed on the support rod; a centering groove is formed in the middle of the base; the slider is slidably disposed in the centering groove; and connecting rods are respectively provided on both sides; one end of the connecting rod is hinged to the side wall of the slider, and the other end is hinged to the bottom of the positioning seat; and a spring is provided between the two positioning seats.

[0012] As an improvement, the perforation surface determining structure includes a fixed bracket, a sliding bracket, pulleys, and a backing plate; a support rod is formed on the top of the positioning seat, and pulleys are rotatably arranged on the fixed bracket and the sliding bracket respectively. The top of the fixed bracket is connected and fixed to the front end of the support rod, and the top of the sliding bracket is slidably arranged on the support rod. After a spring is provided between the sliding bracket and the backing plate fixed on the support rod, the pulleys of the sliding bracket and the fixed bracket abut against each other, and the perforation surface of the cardboard box is arranged between the two pulleys.

[0013] As an improvement, the punching clamp is a U-shaped structure with the opening facing downwards, with round holes at both ends corresponding to the puncher, and one end is fixed to the front end of the puncher, with the punching surface of the cardboard box arranged inside the punching clamp.

A centering groove 10 is reserved in the middle. A limiting guide rod 7 is also fixed on the base 1, and the limiting guide rod 7 is arranged above the front slide rail 3. A pair of positioning seats 2 are mirrored on the left and right sides of the base 1, and the bottom is slidably set on the front slide rail 3 and the limiting guide rod 7. A pair of support rods 5 are fixed on the top (the rear ends of the two support rods 5 are respectively connected and fixed to the two sides of the positioning seat 2). A spring is sleeved on the limiting guide rod 7, and the two ends of the spring are respectively connected to the two side positioning seats 2.

[0027] Centering sandwich structure such as Figure 2As shown, it includes a slider 11, a connecting rod 9, and a clamping plate 6; the clamping plate 6 is arranged vertically and fixed to the front end of the outer support rod 5. The slider 11 is slidably disposed in the centering groove 10, and connecting rods 9 are respectively provided on both sides. One end of the connecting rod 9 is hinged to the side wall of the slider 11, and the other end is hinged to the bottom of the positioning seat 2.

[0028] The structure is determined by the drilling surface, as follows: Figure 3 As shown, it includes a fixed bracket 12, a sliding bracket 13, pulleys 14, and a stop plate 15. A pair of pulleys 14 are rotatably mounted on the fixed bracket 12 and the sliding bracket 13, with each pair of pulleys 14 corresponding to the other and arranged vertically. The top of the fixed bracket 12 is connected and fixed to the front end of the support rod 5. The top of the sliding bracket 13 is slidably mounted on the support rod 5, and a spring is provided between the sliding bracket 13 and the stop plate 15 fixed on the support rod 5. The pulleys 14 of the sliding bracket 13 and the fixed bracket 12 abut against each other, and the perforated surface of the cardboard box enters from below and is clamped between the two pulleys 14.

[0029] The punch 18, sliding column 16, and punch clamp 8 are as follows: Figure 1 As shown, the sliding column 16 is arranged vertically and its bottom is slidably mounted on the rear slide rail 4. The rear slide rail 4 and the sliding column 16 are respectively provided with scales to assist in positioning. The punch 18 is slidably mounted on the sliding column 16 and has a punching clip 8 at its front end. The punching clip 8 is a U-shaped structure with its opening facing downwards. Both ends are provided with round holes corresponding to the punch 18. One end is fixed to the front end of the punch 18, and the inner side wall of the other end is on the same plane as the rear side of the pulley 14 of the fixed bracket 12. After the punching surface of the cardboard box enters the punching clip 8 from below, it is punched by the punch 18. The punch 18 and its usage are both existing mature technologies.
