[0023] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the following will be combined with the appended drawings of the embodiment of the utility model. Figure 1-4 , the technical scheme of the embodiment of the utility model is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0024] like Figure 1-4 As shown: This embodiment provides a carton production punching device, including a punching seat 100, two brackets 101 are fixedly connected to the top of the punching seat 100, a side of the bracket 101 close to the middle of the punching seat 100 is fixedly connected to a slide rail 102, a support plate 103 is slidably connected between the two slide rails 102, a screw rod 107 is rotatably connected between the inner walls of both ends of the slide rail 102, the screw rod 107 is threadedly connected to the support plate 103, a sprocket wheel 108 is fixedly connected to the middle of one end of the screw rod 107, and the two sprocket wheels 108 are connected by a chain 109. A motor 110 is fixedly connected to the middle of one end of the rail 102, and the output shaft of the motor 110 is fixedly connected to the middle of one end of the adjacent screw rod 107. A perforated telescopic column 104 is fixedly connected to the bottom center of the support plate 103, and the telescopic end of the perforated telescopic column 104 is fixedly connected to the support plate 105. A perforated tube 106 is fixedly connected to the bottom center of the support plate 105. The perforated tube 106 is hollow. An avoidance groove 111 is opened in the middle of the perforated seat 100. The avoidance groove 111 is consistent with the guide of the slide rail 102. The bottom four corners of the perforated seat 100 are fixedly connected to pillars.

[0025] By controlling the operation of the motor 110, the adjacent screw rod 107 is driven to rotate, so that the adjacent sprocket wheel 108 rotates synchronously, and the chain 109 drives the sprocket wheel 108 on the other side to rotate synchronously, driving the support plate 103 to move along the axial direction of the screw rod 107 in the slide rail 102, so that the punching telescopic column 104 and the punching tube 106 move synchronously, and after moving to a suitable processing position, the telescopic end of the punching telescopic column 104 extends to drive the support plate 105 to move downward, so that the punching plate contacts the cardboard for punching, and the slide rail 102 and the screw rod 107 can move the support plate 103. , thereby expanding the processing range of punching, so that this device can punch a piece of cardboard multiple times, the hollow punching tube 106 is more conducive to the punching work, and the transmission through the sprocket 108, chain 109 and screw rod 107 can drive the support plate 103 and the punching tube 106 to move along the axial direction of the screw rod 107, so that the movement trajectory of the punching tube 106 is always kept at the top of the avoidance groove 111. When the punching is completed, the waste scraps of the cardboard will fall out of the processing area from the avoidance groove 111 to keep the processing area clean. The pillar keeps the avoidance groove 111 at a certain distance from the ground, which is convenient for the waste to fall out.

[0026] Pressure column 201 Figure 2 As shown,

[0027] Two pressure columns 201 symmetrically arranged along the perforated tube 106 are slidably connected between the support plate 105 and the supporting plate 103. The top of the pressure column 201 is provided with the same limiting plate. The bottom of the pressure column 201 is fixedly connected with a fixing plate 204. The diameter of the fixing plate 204 is larger than the diameter of the pressure column 201. The bottom of the fixing plate 204 is fixedly connected with a plurality of pressure blocks arranged in an array. The column of the pressure column 201 located between the fixing plate 204 and the support plate 105 is sleeved with a spring 205. The diameter of the spring 205 is smaller than the diameter of the fixing plate 204.

[0028] When punching holes, the punching telescopic column 104 drives the support plate 105 to move downward, and the support plate 105 compresses the spring 205. The elastic force of the spring 205 drives the fixed plate 204 to move downward, and finally the bottom of the fixed plate 204 is fitted with the cardboard. As the punching telescopic column 104 continues to extend, the spring 205 is further compressed to provide a stronger pressure for the fixed plate 204. At the same time, the punching tube 106 moves downward and contacts the support plate to punch holes. The setting of the fixed plate 204 improves the stability of the cardboard around the punching area during punching, and avoids the deformation or displacement of the cardboard caused by the punching tube 106 affecting the punching quality. The pressure block can increase the friction between the fixed plate 204 and the cardboard, and the limit plate can make the two pressure columns 201 move downward synchronously, thereby improving the stability of the pressure column 201 when moving;

[0029] Fixed telescopic column 202 Figure 1 , 4 As shown,

[0030] The middle part of the bracket 101 is fixedly connected with a fixed telescopic column 202, the telescopic ends of the fixed telescopic column 202 are fixedly connected with a pressing plate 203, the tops of both ends of the pressing plate 203 are fixedly connected with a limiting column 206, the middle part of the limiting column 206 is slidably connected to the adjacent bracket 101, and the tops of the limiting columns 206 located in the same bracket 101 are fixedly connected with the same connecting plate;

[0031] The cardboard is placed on the top of the punching seat 100, and then the two fixed telescopic columns 202 are driven to move downward synchronously, so that the fixed telescopic columns 202 drive the pressing plate 203 to move downward to fix the two ends of the cardboard. At the same time, the limiting columns 206 assist in positioning the two ends of the pressing plate 203 when the pressing plate 203 moves downward, and the two ends of the pressing plate 203 are placed to produce shaking, which affects the fixing effect of the cardboard.

[0032] Working principle:

[0033] The motor 110 is started, and the screw rod 107 is driven to rotate through the chain 109 and the sprocket 108 transmission system. The rotation of the screw rod 107 causes the punching telescopic column 104 and the punching tube 106 fixed on the support plate 103 to move axially along the screw rod 107. When the punching telescopic column 104 moves to a suitable position, its telescopic end extends to drive the support plate 105 to move downward. During the downward movement of the support plate 105, the pressure column 201 contacts the cardboard under the action of the spring 205, providing stable pressure to ensure that the cardboard in the punching area will not be deformed or displaced. The punching tube 106 moves downward with the support plate 105, contacts the cardboard and punches holes. After the punching is completed, the punching telescopic column 104 retracts, and the support plate 105 and the pressure column 201 are reset under the action of the spring 205. In this process, the design of the avoidance groove 111 allows the waste generated by the punching to fall directly into the groove to keep the working area clean. At the same time, the setting of the pillar ensures that there is enough space between the avoidance groove 111 and the ground to facilitate the cleaning of the waste.

[0034] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0035] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
