[0002] With the rapid development of e-commerce, the demand for carton packaging continues to increase. Die-cutting machines, as crucial equipment in carton production, are widely used in the processing of cartons and boxes. During the die-cutting process, the positioning accuracy of the carton directly impacts the die-cutting effect and product quality. However, during transportation, cartons are susceptible to mechanical vibration, external interference, and inherent unevenness in the carton's shape, which can cause the carton to shift, thereby affecting subsequent die-cutting operations.

DETAILED DESCRIPTION
[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.
[0021] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without making any creative efforts shall fall within the scope of protection of the present application.
[0022] like Figures 1 to 5 As shown, an automatic deviation correction device for a carton die-cutting machine includes a shell 101, and a side support frame 106 is slidably connected to the shell 101, and a control panel 107 is fixedly provided on the side support frame 106. A limit plate 109 is fixedly provided on the control panel 107, and a plurality of adjustment rods 108 are slidably connected to the control panel 107. The adjustment rod 108 is also slidably connected to the slide groove of the limit plate 109, and a limit block 110 is slidably provided on the limit plate 109. By controlling the contact between the limit block 110 and the adjustment rod 108, the movement of the adjustment rod 108 is limited by the friction between the limit block 110 and the adjustment rod 108, and a contact rod is provided on the adjustment rod 108, which pushes the carton to move for correction, and adapts to the outer edge position of cartons of different specifications through different positions of the adjustment rod 108.
[0023] Specifically, when in use, the paper box to be die-cut is transported by the conveyor 102. During the movement of the paper box, the contact with the platform of the shell 101 and the shaking of the conveyor 102 will affect the position of the paper box. Therefore, the paper box needs to be corrected before die-cutting. When the conveyor 102 transports the paper box to the die-cutting position, the adjustment plate 121 is controlled to rotate so that the adjustment plate 121 rotates to the top of the conveyor 102, and the adjustment plate 121 blocks the direction of the paper box's advance. The position of the adjustment plate 121 is adjusted in advance, such as Figure 1 As shown, the multiple adjustment plates 121 can adapt to the specific specifications of the paper box, and as the conveying platform 102 continues to convey, close contact between the paper box and the adjustment plates 121 is ensured, avoiding the adjustment plates 121 contacting the paper box and pushing the paper box to further deviate from its position.
[0024] By controlling the control plates 107 on the left and right sides of the conveyor platform 102 to move toward each other, and by pre-adjusting the position of the slide groove of the adjustment rod 108 on the control plate 107, the contact rod on the adjustment rod 108 can be adapted to the specific specifications of the carton. At the same time, it is prevented that the contact rod at a certain point on either side pushes the carton to further deviate when it contacts the offset carton. By using the contact rods and adjustment plates 121 of multiple adjustment rods 108, the front and both sides of the moving path of the carton can be corrected as a whole, rather than controlling the carton for correction by pushing a certain point, thereby avoiding misalignment of the carton during correction and ensuring the accuracy and stability of the carton correction.
[0025] like Figure 2 As shown, a conveying platform 102, a driving shaft 120 and a motor 119 are provided on the housing 101. A plurality of conveyor belts are provided on the conveying platform 102. The driving shaft 120 is connected to the output end of the motor 119 by a belt. A plurality of pre-adjusted adjustment plates 121 are provided on the driving shaft 120. The adjustment plates 121 are inserted between the transmission belts of the plurality of conveying platforms 102.
[0026] Specifically, a plurality of scale grooves are provided on the drive shaft 120. Before use, the scale grooves of the adjustment plate 121 installed on the drive shaft 120 are adjusted according to the specifications of the paper box, so as to obtain adjustment plates 121 with different deflection angles. Then, after the adjustment plates 121 are rotated, all the adjustment plates 121 can contact each edge of the paper box in that direction at the same time, thereby achieving overall correction of the paper box in that direction.
[0027] like Figure 3 As shown, a cylinder 103 is fixedly provided on the outer shell 101, and a control rod 104 is rotatably provided on the output end of the cylinder 103. A sliding frame 105 is fixedly provided on the outer shell 101, and an end of the control rod 104 that is not connected to the output end of the cylinder 103 is slidably connected to the sliding frame 105. A side support frame 106 is rotatably connected to this end of the control rod 104, and the side support frame 106 is also slidably connected to the sliding frame 105.
[0028] Specifically, when in use, the air cylinder 103 is activated, and the output rod of the air cylinder 103 pulls one end of the control rod 104, and the other end of the control rod 104 slides on the sliding frame 105, thereby pushing the side support frame 106 to slide outward on the sliding frame 105. The side support frame 106 then pulls the control plate 107 outward, thereby causing the adjustment rod 108 on the control plate 107 to move away from the carton. When the carton needs to be corrected, the air cylinder 103 pushes one end of the control rod 104, and the other end of the control rod 104 slides inward on the sliding frame 105, thereby pulling the side support frame 106 and the control plate 107 inward, thereby causing the contact rod on the adjustment rod 108 to approach and contact the side edge of the carton.
[0029] like Figure 4 and Figure 5 As shown, a sliding shaft 112 is fixedly provided on the limit plate 109, an intermediate plate 113 is slidably connected to the sliding shaft 112, a first end of a spring 111 is fixedly provided on the intermediate plate 113, and a second end of the spring 111 is fixedly connected to the limit block 110, a hole is provided on the limit block 110, the sliding shaft 112 passes through the hole of the limit block 110, a top plate 118 is provided on the sliding shaft 112, and multiple sliding shafts 112 are connected through the top plate 118.
[0030] The first ends of multiple torsion springs 115 are fixedly provided on the middle plate 113, the second ends of the torsion springs 115 are fixedly provided with a rotating shaft 114, a connecting plate 116 is fixedly provided on the rotating shaft 114, a hook is provided on the connecting plate 116, a connecting rod 122 is fixedly provided on the connecting plate 116, and two adjacent connecting plates 116 are connected through the sliding shaft 112.
[0031] A plurality of limiting shafts 117 are fixedly provided on the limiting plate 109 , and the limiting shafts 117 cooperate with the hooks on the connecting plate 116 .
[0032] Specifically, before use, adjust the position of the adjustment rod 108 on the control panel 107 according to the specifications of the paper box, such as Figure 5When the lever 112 is in the unlocked position, the spring 111 is released and the lever 113 is released, and the lever 113 is released, and the lever 113 is released, and the lever 113 is released, and the lever 113 is released, and the lever 113 is released, and the lever 113 is released, and the lever 113 is released, and the lever 113 is released, and the lever 113 is released, and the lever 113 is released, and the lever 113 is released, and the lever 113 is released, and the lever 113 is released, and the lever 113 is released, and the lever 113 is released
[0033] When adjusting the adjustment rod 108, the middle plate 113 can be manually controlled to lift on the sliding shaft 112, so that the limit block 110 is pulled away from the adjustment rod 108 through the spring 111, thereby reducing the friction on the adjustment rod 108, avoiding damage caused by friction, resulting in insufficient friction in subsequent contact, and affecting the correction of the paper box.
[0034] After adjusting the position of the adjusting rod 108, press the middle plate 113 downward, so that one end of the hook on the connecting plate 116 contacts the limit shaft 117, and under the action of the arc surface of the hook end of the connecting plate 116, push the connecting plate 116 to rotate, so that the hook end of the connecting plate 116 slides along the surface of the limit shaft 117, and then the hook of the connecting plate 116 hooks the limit shaft 117, and then releases the pressure on the middle plate 113. Under the restriction of the connecting plate 116, the middle plate 113 continues to exert downward pressure on the spring 111, thereby pushing the limit block 110 to close contact with the adjusting rod 108 through the elastic force of the spring 111, maintaining the friction between the limit block 110 and the adjusting rod 108, and fixing the position of the adjusting rod 108.
[0035] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
