[0002] Cardboard box production is a process involving the processing of cardboard material into boxes of various sizes, shapes, and structures. This process typically involves a series of ordered steps designed to meet the needs of packaging, protecting, and transporting a variety of goods. During cardboard box production, perforations for carrying handles are made on the cardboard sheets.

[0003] Chinese Patent 202322799603.X proposes a cardboard punching device for cardboard production. By activating a lifting cylinder, a pallet can be moved upward in a fixed groove, causing a large number of stacked cardboard pieces on top of the pallet to move upward as well. Then, by activating a pushing cylinder, a pusher plate can push the cardboard pieces on the top layer to the bottom of the punching machine, thus achieving electric feeding. However, the waste generated during punching moves along with the cardboard pieces and cannot be automatically cleaned, requiring manual processing, which increases the production cost for enterprises. Therefore, a punching device for carton production is proposed to solve the above problems. Utility Model Content

Vertical plates 2 are fixedly installed on both the front and rear sides of the bottom right end of the conveyor belt body 1. A cavity is provided at the right end of the conveyor belt body 1. A movable plate 3 is provided on the right side of the conveyor belt body 1 and below the cavity. A collection box 4 is fixedly installed on the back of the rear vertical plate 2. A driving mechanism 5 is provided on the vertical plate 2. A punching mechanism 6 is provided above the conveyor belt body 1. A lower mold 7 is fixedly installed at the top center of the movable plate 3. A base frame 8 is fixedly installed at the bottom of the two vertical plates 2. An ejector block 9 is fixedly installed at the top center of the base frame 8.

[0019] In this embodiment, a feeding groove 31 is fixedly installed on the top of the movable plate 3 and on the rear side of the lower mold 7, and negative pressure suction cups 32 are embedded on the top of the movable plate 3 and on both the left and right sides of the lower mold 7.

[0020] Specifically, the negative pressure suction cup 32 can hold the two sides of the cardboard box, preventing the cardboard box from shifting during punching.

[0021] In this embodiment, a through hole 71 is provided at the top center of the lower mold 7, and the through hole 71 extends below the movable plate 3. The through hole 71 matches the ejector block 9.

[0022] Specifically, the through hole 71 can be used to hold the punching waste.

[0023] In this embodiment, the drive mechanism 5 includes a push rod frame 51, an electric push rod 52, and an L-shaped rod 53. The push rod frame 51 is fixedly installed at the bottom center of each of the two vertical plates 2. The electric push rod 52 is embedded in the push rod frame 51. Slide grooves are opened at both ends of the opposite side of the two vertical plates 2. An L-shaped rod 53 with one end fixedly connected to the bottom of the movable plate 3 is slidably installed inside the slide groove. A connecting rod is fixedly installed on the opposite side of the front L-shaped rod 53 and the opposite side of the rear L-shaped rod 53. The output end of the electric push rod 52 is fixedly connected to the connecting rod.

[0024] Specifically, the electric push rods 52 on both sides can move the movable plate 3 vertically at the same time.

[0025] In this embodiment, a drop hole 21 is provided on the back of the rear vertical plate 2 and above the collection box 4. A feed plate 22 is provided on the front of the rear vertical plate 2 and above the drop hole 21. A hydraulic push rod 23 is embedded on the front of the front vertical plate 2. A scraper 24 is fixedly installed at the output end of the hydraulic push rod 23.

[0026] Specifically, the hydraulic push rod 23 drives the scraper 24 to move forward, pushing the waste material ejected from the lower mold 7 to the discharge trough 31, and then from the discharge trough 31 through the discharge plate 22 into the collection box 4.

[0027] In this embodiment, the punching mechanism 6 includes an L-shaped mounting bracket 61, a cylinder 62, and an upper mold 63. The L-shaped mounting bracket 61 is fixedly installed at the center of the front side of the conveyor belt body 1. The cylinder 62 is embedded at the top front end of the L-shaped mounting bracket 61. The upper mold 63 is fixedly installed at the output end of the cylinder 62.

[0028] Specifically, the operating cylinder 62 moves the upper mold 63 downwards to get closer to the lower mold 7, and performs the punching operation on the carton board.

[0029] The working principle of the above embodiments is as follows:

[0030] (1) Place the cardboard to be punched on the conveyor belt body 1. As the conveyor belt body 1 is conveyed, the cardboard moves above the movable plate 3. At the same time, operate the electric push rods 52 on both sides to move the movable plate 3 upward. After the lower mold 7 is attached to the bottom of the cardboard, operate the negative pressure suction cup 32 to adsorb the cardboard.

[0031] (2) The operating cylinder 62 moves the upper mold 63 downward to be close to the lower mold 7 to perform the perforation operation of the carton board. When the lower mold 7 is inserted into the through hole 71, the waste material generated during the perforation can be pushed into the through hole 71. Then, the operating cylinder 62 moves the upper mold 63 back to its original position, the negative pressure suction cup 32 releases the carton board from the adsorption and fixation state, and the conveyor belt body 1 transports the perforated carton board away.

[0032] (3) Operate the electric push rod 52 to move the movable plate 3 downwards. When the ejector block 9 ejects the punching waste in the through hole 71, operate the hydraulic push rod 23 to drive the scraper 24 to move forward and push the waste ejected by the lower mold 7 to the discharge groove 31. The waste then falls from the discharge groove 31 through the discharge plate 22 into the collection box 4. In this way, the automatic cleaning and collection of punching waste is realized.
