DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 As shown, a corrugated cardboard punching device according to an embodiment of the utility model includes a workbench 1, on which a punching assembly and a limiting assembly are arranged, the punching assembly includes a support plate 2 and a punching die base 20 arranged on the support plate 2, the support plate 2 is also provided with a driving assembly, the driving assembly is connected to the punching die base 20 to drive the punching die base 20 to perform a punching action, the limiting assembly includes two fixing ears 3 correspondingly arranged on the left and right sides of the punching die base 20, the two fixing ears 3 are movably penetrated with a sliding rod 30, and the lower ends of the two sliding rods 30 are commonly connected to a pre-pressing frame plate 31.

[0021] When in use, the corrugated cardboard to be punched is placed on the workbench 1, and the punching component is started. Specifically, the punching die holder 20 is controlled to slide radially up and down through the driving component. The punching die holder 20 moves and punches the cardboard through the punching head installed above the punching die. A pre-pressing frame plate 31 is connected to the bottom of the punching die holder 20 through a sliding rod 30. The pre-pressing frame plate 31 pre-presses the position of the cardboard to be punched before the punching head contacts the cardboard to ensure that the cardboard remains stable during punching and does not cause punching deviation. The punching and limiting of the cardboard are realized synchronously, thereby improving the operation convenience and processing efficiency of the equipment.

[0022] The upper end of the slide rod 30 is connected to a limit ring 32 , and the outer ring of the slide rod 30 is located between the pre-stressing frame plate 31 and the fixing ear 3 and is sleeved with a spring member 33 .

[0023] When in use, the maximum distance between the pre-pressing frame plate 31 and the punching die base 20 is limited by setting a limit ring 32, and at the same time, the pre-pressing frame plate 31 and the punching die base 20 are prevented from being separated;

[0024] Before the punching die holder 20 moves down and the punching head contacts the paperboard, the pre-pressing frame plate 31 contacts the paperboard and pre-presses it. After the pre-pressing frame plate 31 presses the paperboard, the punching die holder 20 continues to move down and causes the spring member 33 to be in an energy storage state. At this time, the pre-pressing frame plate 31 always presses the paperboard due to the elastic force of the spring member 33 and the sliding cooperation between the slide rod 30 and the fixed ear 3.

[0025] After the punching is completed, the punching die holder 20 and the punching head are reset, and the pre-pressing frame plate 31 always presses the cardboard before the punching head and the cardboard are out of contact. When the punching head and the cardboard are out of contact, the punching die holder 20 continues to move up until the pressing force of the pre-pressing frame plate 31 on the cardboard disappears, and the punching of the cardboard is completed.

[0026] A rubber ring 34 is embedded at the center of the lower end surface of the pre-stressing frame plate 31 and distributed along the frame shape.

[0027] When in use, the rubber ring 34 is provided to provide buffer protection between the pre-pressing frame plate 31 and the paperboard, so that the pre-pressing frame plate 31 and the paperboard are in soft contact, ensuring that the pre-pressing frame plate 31 presses the paperboard stably, while preventing the pre-pressing frame plate 31 from causing damage to the paperboard due to the pressing limit;

[0028] The rubber ring 34 is embedded in the lower surface of the pre-pressing frame plate 31 to facilitate daily maintenance and replacement.

[0029] The driving assembly includes a driving source 21 fixed to the top surface of the support plate 2 . The output shaft of the driving source 21 penetrates the support plate 2 and is drivingly connected to the punching die holder 20 .

[0030] When in use, the driving source 21 (preferably an electric push rod) is started for punching, and the output shaft of the driving source 21 drives the punching die holder 20 to slide up and down so that the punching die holder 20 can achieve stable punching.

[0031] Two positioning rods 22 are correspondingly arranged on the top surface of the punching die base 20 , and sleeves 23 are arranged at the corresponding positions of the two positioning rods 22 on the support plate 2 . The upper ends of the two positioning rods 22 extend through and extend above the sleeves 23 and are in sliding cooperation with the sleeves 23 .

[0032] When in use, the working stability of the punching die holder 20 is effectively improved through the sliding cooperation between the two positioning rods 22 and the support plate 2, thereby improving the punching accuracy;

[0033] The sleeve 23 is provided to effectively improve the sliding smoothness between the positioning rod 22 and the support plate 2 .

[0034] The workbench 1 is provided with a blanking trough 10 at a position corresponding to the punching die base 20 , and a blanking channel 11 is fixedly installed at the lower open end of the blanking trough 10 .

[0035] When in use, the waste material after punching the cardboard can be discharged by providing the blanking chute 10, and the blanking channel 11 guides and collects the waste material to ensure the neatness of the equipment when working.

[0036] An assembly step surface 12 is formed around the inner side of the upper opening end of the blanking chute 10 , and a fixed frame plate 13 is installed on the assembly step surface 12 , and the inner circumference of the fixed frame plate 13 is densely covered with brush hairs 14 .

[0037] When in use, the punching head of the punching die holder 20 enters the blanking groove 10 and passes through the fixed frame plate 13. After the punching is completed, the punching die holder 20 and the punching head are reset. At this time, the brush bristles 14 on the inner circumference of the fixed frame plate 13 brush off the punching waste adhered to the punching head and drop it into the blanking channel 11, so as to prevent the punching waste from affecting the processing of the next cardboard due to the adhesion of the punching waste to the punching head;

[0038] The fixed frame plate 13 is detachably mounted on the assembly step surface 12 by bolts, screws or other fasteners, so as to facilitate daily maintenance and replacement.

[0039] Two limit baffles 4 are correspondingly arranged on the left and right sides of the top surface of the workbench 1. The limit baffles 4 are slidably matched with the workbench 1 to enclose the processing area of ​​the cardboard.

[0040] When in use, the processing area of ​​the cardboard is limited by two limit baffles 4. The two limit baffles 4 slide together with the workbench 1 to adjust the processing area according to different cardboard sizes, so that the cardboard can be accurately and quickly placed in the processing area and punched.

[0041] The electrical components mentioned in this article are all connected to an external main controller and 220V mains electricity, and the main controller can be a conventional known device for controlling a computer or the like.

[0042] It should also be pointed out that the terms used in the present invention, such as “front”, “rear”, “vertical”, “horizontal”, etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description.
