Description

Technical Field

[0001] The utility model relates to the technical field of carton processing equipment, and particularly relates to a carton cardboard correction device. Background Art

[0002] In the production process of cartons, a series of operations such as printing, die-cutting, and laminating are involved. After the cardboard is processed, the corresponding two sides of the cardboard need to be nailed together to form a carton. Before the carton is formed, after the cardboard is embossed, generally, a bending mechanism is set on a conveyor belt to fold the cardboard. After folding, it is transported to the next process for binding or packing. Since the upper and lower layers of the carton may not be aligned when folding the carton or the carton may be skewed when being transported to the binding part, resulting in the deviation of the binding position (as Figure 5 shown, there is a misalignment between the first side a and the fourth side d of the cardboard and the second side b and the third side c of the cardboard), which affects the subsequent binding of the carton and causes the carton to be skewed. Therefore, in order to solve this problem, a device capable of correcting the folded cardboard needs to be designed to avoid the above problems. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further describes the utility model in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0021] like Figures 1-5 A carton paperboard correction device shown is used to correct the misalignment of the paperboard surface of the folded paperboard, including two groups of correction components 1 arranged symmetrically, the correction component 1 includes a belt conveyor 3 symmetrically on both sides of the bracket 2, and an adjustable pressing roller mechanism 4 is arranged at the feeding port of the belt conveyor 3. The pressing roller mechanism 4 can connect the folded paperboard 6 from the previous process so that it can smoothly enter the belt conveyor 3.

[0022] The pressing roller mechanism 4 includes a pressing roller wheel 41, which is arranged at the rear end of a swing arm 42 rotatably connected to the bracket 2. A cylinder for pushing the swing arm 42 to rotate is arranged at the front end of the swing arm 42. The pressing roller wheel 41 rotates through a pressing roller transmission system 43 that is transmission-connected thereto. The pressing roller transmission system 43 includes a first driving sprocket 431, an intermediate sprocket 432 and a second driving sprocket 433. The first driving sprocket 431 is driven by a motor and is transmission-connected to the intermediate sprocket 432 and the second driving sprocket 433 through a transmission chain. The second driving sprocket 433 is arranged at the rear end of the swing arm 42, and the pressing roller wheel 41 is arranged on the second driving sprocket 433. Therefore, when the swing arm 42 reciprocates through the cylinder arranged at its front end, the pressing roller wheel 41 at its rear end can reciprocate up and down in the vertical direction. The up and down movement of the pressing roller wheel 41 can realize the compression and loosening of the cardboard 6, which is convenient for the cardboard 6 to enter the device and also convenient for the adsorption device 7 to adsorb the cardboard 6.

[0023] The correction mechanism 5 is arranged above the belt conveyor 3, and includes a correction disk 51 driven to rotate by a sprocket. The correction disk 51 is close to the feed port of the belt conveyor 3 and is provided with a correction paddle 52. The correction paddle 52 is provided with a step suitable for the cardboard 6. The correction paddle 52 rotates with the correction disk 52 and cooperates with the adsorption device 7 to correct the cardboard 6.

[0024] The adsorption device 7 includes a plate body 71 arranged above the belt conveyor 3. The plate body 71 is driven to move up and down by a cylinder. The plate body 71 is a cavity structure and a duct 72 is connected to the top of the plate body 71. A plurality of openings 73 are provided at the bottom. The duct 72 is connected to the pump body and can extract the air inside the plate body 71 so that the cardboard 6 under the plate body 71 is adsorbed to the bottom of the plate body 71. When the cardboard 6 is transported to the bottom of the plate body 71 by the belt conveyor 3, the cylinder drives the plate body 71 to move downward and press the cardboard 6. The duct 72 extracts the internal air through the pump body to generate negative pressure and adsorbs the cardboard 6 through the openings 73 so that it is adsorbed to the bottom of the plate body 71. Then the plate body 71 moves upward so that the cardboard 6 can be separated from the belt conveyor 3.

[0025] A carton board correction device mentioned in the present utility model, when in specific use, the misaligned board 6 enters from the feed port. The entering state is that the first side a and the second side b of the board are the upper surfaces, and the third side c and the fourth side d of the board are the lower surfaces. When entering this device, the pressure roller 41 of the pressure roller mechanism 4 moves downward to press the board 6 tightly and cooperate with the belt conveyor device 3 to transport the board forward. When the tail of the board 6 passes below the pressure roller 41, the pressure roller 41 retracts upward. At the same time, the plate body 71 moves downward to press the board 6 tightly. The air duct 72 extracts internal air through the pump body to generate negative pressure and adsorbs the board 6 through the opening 73, making it adsorbed on the bottom of the plate body 71. Subsequently, the plate body 71 moves upward so that the board 6 can be separated from the belt conveyor device 3. At this time, the third side c and the fourth side d of the board 6 are in a hanging state due to gravity. The position of the board 6 is lifted at this time so that its tail end can be contacted by the correction dial 52. When the correction dial 52 rotates, its stepped surfaces contact the upper surface and the lower surface of the board 6 respectively. The stepped difference can make the misaligned part move forward to realize the correction of the board 6. When the correction is completed, the plate body 71 moves downward to press the board 6 tightly, and the air duct 72 introduces air into the plate body 71 to restore normal air pressure. The board 6 falls on the belt conveyor device 3 due to gravity, the plate body 71 resets upward, and the board 6 leaves this device with the belt conveyor device 3, thus completing a correction process.

[0026] The above-described embodiments merely describe the preferred embodiments of the present utility model, and do not limit the concept and scope of the present utility model. Without departing from the design concept of the present utility model, various modifications and improvements made by those of ordinary skill in the art to the technical solutions of the present utility model shall fall within the protection scope of the present utility model. The technical content claimed by the present utility model has been fully recorded in the claims.
