Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard box creasing technology, and in particular to a corrugated cardboard box creasing processing device. Background Technology

[0002] Corrugated cardboard is die-cut, creasing, and stapling or gluing to make corrugated boxes. Corrugated boxes are one of the most widely used packaging products, consistently ranking first in usage among all packaging products, including calcium-plastic corrugated boxes. Besides protecting goods and facilitating warehousing and transportation, they also beautify and promote products. Corrugated boxes are considered environmentally friendly products, benefiting both environmental protection and ease of loading and unloading. After the cardboard is formed, it generally needs to be creasing to assemble the cardboard into boxes. Common corrugated box creasing machines are mostly manually operated, using creasing rollers for the creasing process.

[0003] A corrugated cardboard box creasing processing device is disclosed in Chinese Patent CN222136079U. This device includes a base with a creasing structure mounted on its upper side. The creasing structure comprises two lead screw modules, two sliding seats, two slots, two crossbars, a connecting rod, two creasing wheels, two adjusting components, a base, a rectangular through hole, and two limiting grooves. During operation, the two lead screw modules drive the creasing wheels to move longitudinally, allowing the creasing wheels to cooperate with the limiting grooves to automatically creasing the corrugated cardboard box. Simultaneously, the two adjusting components can change the distance between the creasing wheels and the limiting grooves, thereby adjusting the creasing depth of the corrugated cardboard box.

[0004] However, compared with existing technologies and comparative solutions, it can be seen that when adjusting the distance between the creasing wheel and the limiting groove, the corrugated carton creasing processing device needs to be adjusted at both ends separately. This may result in one end being adjusted to a larger height and the other end being adjusted to a smaller height, causing the creasing wheel itself to be non-horizontal and affecting the creasing effect. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a corrugated carton creasing processing device.

[0006] The purpose of this utility model is achieved through the following technical solution: a corrugated cardboard box creasing processing device, including a machine body, a positioning plate fixedly connected to the top of the machine body, a creasing mechanism provided above the machine body, the creasing mechanism including a fixed frame, a rolling shaft provided on one side of the fixed frame, a transmission shaft rotatably connected inside the rolling shaft, driven bevel gears fixedly connected to both ends of the transmission shaft, a creasing wheel fixedly connected to the rolling shaft, a screw threadedly connected to the top of the fixed frame, and a driving bevel gear fixedly connected to one end of the screw.

[0007] The drive shaft is rotatably connected to the middle of the driven bevel gear by a support frame. The support frame is slidably connected inside the fixed frame. The size of the support frame is adapted to the size of the internal sliding groove of the fixed frame. A buckle is provided on one side of the support frame. One end of the buckle is hinged to one side of the support frame, and the other end is engaged inside the driven bevel gear. A spring is provided below the support frame.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, and in part will be obvious from the description or may be learned by practice of the invention.

[0021] like Figure 1-3 As shown, a corrugated cardboard box creasing processing device includes a body 1, a positioning plate 4 fixedly connected to the top of the body 1, a creasing mechanism provided above the body 1, the creasing mechanism including a fixed frame 3, a rolling shaft 10 provided on one side of the fixed frame 3, a transmission shaft 12 rotatably connected inside the rolling shaft 10, driven bevel gears 9 fixedly connected to both ends of the transmission shaft 12, a creasing wheel 11 fixedly connected to the rolling shaft 10, a screw 6 threadedly connected to the top of the fixed frame 3, a driving bevel gear 7 fixedly connected to one end of the screw 6, and the driving bevel gear 7 meshing with the driven bevel gear 9.

[0022] A support frame 8 is rotatably connected to the drive shaft 12 and the driven bevel gear 9 at the middle. The support frame 8 is slidably connected within the fixed frame 3, and its size is adapted to the size of the internal sliding groove of the fixed frame 3. A buckle 15 is provided on one side of the support frame 8. One end of the buckle 15 is hinged to one side of the support frame 8, and the other end is locked inside the driven bevel gear 9. When adjusting the indentation depth, the driven bevel gear 9 rotates and pushes up the end of the buckle 15 away from the support frame 8 to prevent the buckle 15 from affecting the rotation of the gear. After adjustment, the end of the buckle 15 away from the support frame 8 will be locked inside the driven bevel gear 9 to prevent the driven bevel gear 9 from rotating in reverse due to the rotation of the rolling shaft 10. A spring 13 is provided below the support frame 8 to apply an upward thrust to the support frame 8 when adjusting the height.

[0023] As a preferred technical solution of this utility model, the top of the machine body 1 is rotatably connected to a roller 2, which can play the role of limiting the corrugated cardboard in the creasing process.

[0024] As a preferred technical solution of this utility model, a bracket 14 is fixedly connected to the bottom of the machine body 1, so that the machine body is away from the ground and the operator can operate it conveniently.

[0025] As a preferred technical solution of this utility model, a positioning plate 4 is fixedly connected to the top of the machine body 1. Before entering the creasing mechanism, the corrugated cardboard is positioned by the positioning plate 4 to prevent the corrugated cardboard from tilting during the conveying process.

[0026] As a preferred technical solution of this utility model, a conveying wheel 5 is provided on the inner side of the positioning plate 4. The conveying wheel 5 can drive the corrugated cardboard along the positioning plate 4 into the creasing mechanism.

[0027] The work process is as follows:

[0028] When starting to process corrugated cardboard, the cardboard is placed above the conveyor roller 5 and positioned by the positioning plate 4 to prevent skewing during the conveyor roller 5's transport of the cardboard.

[0029] Before entering the pressing device, the corrugated cardboard is squeezed and limited by roller 2 to prevent the corrugated cardboard from shifting during the creasing process. After being creasing by creasing roller 11, the corrugated cardboard enters the finished product stack from the other side.

[0030] When adjusting the indentation depth, the screw 6 is rotated to drive the active bevel gear 7 to rotate. The active bevel gear 7 meshes with the driven bevel gear 9 to drive the transmission shaft 12 to rotate. The rotation of the transmission shaft 12 drives the gear at the other end to rotate, achieving the effect of adjusting the height at both ends at the same time. This prevents the height adjustment at both ends from being inconsistent and improves the yield of corrugated cardboard processing.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
