Description

Technical Field

[0001] This utility model belongs to the field of cardboard processing technology, specifically relating to a tangential drive structure for an electric plateless mold. Background Technology

[0002] In the paperboard processing industry, paperboard needs to be creasing and trimmed to facilitate folding into various boxes, cartons, or embossed trademarks. Currently, creasing and trimming are performed either manually or by machine, but only partial processes are completed. Automatic paperboard collection and scrap recycling are not possible, increasing the workload for operators and impacting the processing progress.

[0003] To address this, a cardboard creasing and cutting device, with announcement number "CN106273655B", includes a device base, a drive wheel and a driven wheel mounted on the device base, belts fitted onto the drive wheel and the driven wheel, a lower die that can be raised and lowered on the device base, an upper die positioned above the lower die, the drive wheel connected to a motor capable of driving the drive wheel to rotate, and the motor and the lower die respectively connected to a control component. This cardboard creasing and cutting device has a simple structure, is locally manufactured, and can conveniently and quickly complete the creasing and cutting process of cardboard, fully automating the creasing and cutting process, thereby effectively reducing the labor intensity of operators and significantly improving the processing efficiency of cardboard.

[0004] However, although the control unit controls the lower die to rise and fit with the upper die, and the processing cavities of the upper and lower dies complete the creasing and cutting processes on the unprocessed cardboard, thereby completing the processing of the unprocessed cardboard and forming cardboard that meets the requirements, the following obvious defects still exist in the use of the above-mentioned cardboard creasing and cutting device: the above-mentioned cutting device performs cutting work through the upper and lower dies, so it can only perform cutting operations on cardboard with customized cutting widths, and cannot drive and adjust the cutting device according to the size of the transverse width of the cardboard cutting line, thus reducing the cardboard cutting range of the cutting device. Utility Model Content

[0005] The purpose of this invention is to provide a tangential drive structure for an electric die-cutting system to solve the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tangential drive structure for an electric die-cutting system, comprising:

[0007] The frame has a paper roller rotatably mounted on the bottom inner side for cutting the paperboard. The rear side of the paper roller is equipped with a guide roller that works with the paper roller to feed the paperboard into the rolling pressing position. The upper vertical end of the paper roller is provided with a guide rail for laterally adjusting the pressing position of the paperboard. The guide rail is slidably connected to a transverse drive frame via a rack.

[0008] A transverse cylindrical rod is fixed transversely to the inner side of the frame. A rotating sleeve that drives the rolling and cutting of the cardboard is movably connected to the transverse cylindrical rod. A cutting disc that cuts the feeding cardboard is provided on the outside of the rotating sleeve. A driving tooth that makes the cutting disc roll and cut is sleeved on one end of the rotating sleeve.

[0009] Preferably, the paper guide roller is vertically slidably provided with a lifting pressure roller that is positioned according to the thickness of the paperboard at its upper end. The rotating shafts at both ends of the lifting pressure roller extend through the positioning vertical grooves provided on both sides of the frame to the outside of the frame, so as to realize the roller pressing and conveying of the paperboard and keep the paperboard in a constant position during conveying.

[0010] Preferably, the upper ends of both sides of the machine frame are provided with cylinder components, and one end of the piston rod of the cylinder component is provided with a bearing sleeve that passes through the rotating shafts at both ends of the lifting pressure roller, thereby driving the lifting pressure roller to press down and roll the paperboard for conveying.

[0011] Preferably, a servo motor A is provided on the rear side wall inside the transverse drive frame, and a transverse drive tooth is provided on the shaft of the servo motor A. The transverse drive tooth meshes with a drive rack installed at the end of the guide rail, so that the pneumatic drive cutting method is replaced with rolling cutting, which can improve the efficiency of cardboard cutting.

[0012] Preferably, the guide rail is provided with limiting strips at the front and rear, and the limiting strips are movably limited in the limiting guide grooves provided on the inner two side walls of the transverse drive frame. A servo motor B is provided on the outer side of the transverse drive frame, and the rotating shaft of the servo motor B passes through to the inner end of the transverse drive frame (6) and is provided with a main drive tooth, so that the cutting disc rotates to cut the paperboard and can roll and convey the paperboard.

[0013] Preferably, the two ends of the rotating sleeve are rotatably mounted on the inner side of the transverse drive frame through sleeved bearing components, and the drive teeth on the rotating sleeve mesh with the main drive teeth on the servo motor B to drive the tangent disc to perform rolling and rapid cutting of the paperboard, thereby realizing the rotation of the tangent disc to perform rolling cutting operation on the paperboard.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows: The tangent drive structure of this electric plateless mold, through the driving rack set on the guide rail, the transverse drive frame utilizes the sliding of the driving teeth on the servo motor A on the driving rack, and the sliding of the transverse drive frame drives the tangent disk on the rotating sleeve to perform transverse sliding adjustment. In the operation of tangling paperboard at different transverse spacings, the servo motor A uses the transverse drive teeth to mesh with the driving rack to slide on the guide rail, which allows the transverse drive frame to drive the rotating sleeve to move laterally on the transverse cylindrical rod, thereby driving the tangent disk to perform transverse movement adjustment. After the transverse tangent spacing is adjusted, the servo motor B drives the main drive teeth to mesh and drive the rotating sleeve to rotate on the transverse cylindrical rod, while the tangent disk rotates to roll and cut the paperboard. Thus, it can perform rolling tangling processing on paperboard with different tangent positions and spacing widths, and shortens the time for changing the tangent mold.

[0015] By combining servo motor B, main drive gear, drive gear, rotating sleeve, transverse cylindrical rod, and tangent disc, the cardboard is pressed and rolled by the guide roller and lifting pressure roller. Servo motor B drives the main drive gear to rotate, and the main drive gear meshes with the drive gear to drive the rotating sleeve to rotate. The tangent disc also rotates at high speed. At the same time, the paper conveyor roller rotates synchronously, so the paper conveyor roller and tangent disc can be used as feeding conveyor rollers for the cardboard. Simultaneously, the tangent disc can perform tangling operations on the surface of the cardboard at high speed during the cardboard conveying. Thus, tangling operations can be performed on the cardboard simultaneously with synchronous feeding and conveying. This tangling drive method can speed up the cardboard tangling processing capacity compared to pneumatic drive tangling. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a tangential drive structure for an electric die-free system, comprising:

[0023] The frame 1 has a paper roller 2 rotatably mounted on the bottom inner side for cutting the paperboard. One end of the paper roller 2 has a rotating shaft extending through to the outside of one side of the frame 1 and is connected to a drive motor. The drive motor is mounted on the outside of the frame 1 and drives the paper roller 2 to rotate to feed the paperboard. The rear side of the paper roller 2 is provided with a guide roller 3 that cooperates with the paper roller 2 to feed the paperboard into the rolling pressing position. Before the paperboard is cut, it is fed into the cutting disc 9 and the paper roller 2 by the guide roller 3. The upper vertical end of the paper roller 2 is provided with a guide rail 5 for lateral adjustment of the paperboard pressing position, so that the transverse drive frame 6 can be laterally adjusted and moved. The guide rail 5 slides on the transverse drive frame 6 through a rack and pinion, which drives the cutting disc 9 to move laterally. The number of transverse drive frames 6 and cutting discs 9 is set according to the actual use.

[0024] A transverse cylindrical rod 7 is fixed transversely to the inner side of the frame 1, so that the rotating sleeve 8 drives the tangent disc 9 to perform transverse adjustment on the transverse cylindrical rod 7. The rotating sleeve 8, which drives the rolling tangent of the cardboard, is movably connected to the transverse cylindrical rod 7, so that the tangent disc 9 can move laterally or rotate on the transverse cylindrical rod 7 to perform tangent. The tangent disc 9, which performs tangent cutting on the cardboard, is provided on the outside of the rotating sleeve 8. The cardboard can be rolled and tangented. A drive tooth 10 is sleeved on one end of the rotating sleeve 8 to make the tangent disc 9 roll and cut, so that the tangent disc 9 can be rotated after being adjusted laterally on the transverse cylindrical rod 7.

[0025] The paper guide roller 3 is vertically slidably equipped with a lifting roller 4 at its upper end, which presses down and positions the paperboard according to its thickness. This allows the paperboard to be pressed down and positioned during transport, maintaining a constant feeding position. The rotating shafts at both ends of the lifting roller 4 extend through the positioning vertical grooves on both sides of the frame 1 to the outside of the frame 1, allowing the lifting roller 4 to rotate in tandem with the paper guide roller 3 to position and transport the paperboard. Cylinder components 11 are provided at the upper ends of both sides of the frame 1 to push the lifting roller 4 for height adjustment. The piston rod of each cylinder component 11... One end is provided with a bearing sleeve 12 that passes through the rotating shafts at both ends of the lifting pressure roller 4, so that the lifting pressure roller 4 can rotate. The servo motor A13 is provided on the rear side wall inside the transverse drive frame 6, which drives the transverse drive gear 14 to rotate. The servo motor A13 has a transverse drive gear 14 on its rotating shaft. The transverse drive gear 14 generates driving force to make the transverse drive frame 6 slide laterally. The transverse drive gear 14 is engaged with a drive rack 15 installed at the end of the guide rail 5, so that the transverse drive frame 6 moves laterally to adjust the tangential position.

[0026] The guide rail 5 is provided with limiting plates 16 at the front and rear to keep the transverse drive frame 6 sliding horizontally and linearly during transverse movement. The limiting plates 16 are movably limited in the limiting guide grooves provided on the inner two side walls of the transverse drive frame 6 to maintain stability during the transverse adjustment of the tangent disc 9. A servo motor B17 is provided on the outer side of the transverse drive frame 6 to drive the main drive gear 18 to rotate. The rotating shaft of the servo motor B17 passes through to the inner end of the transverse drive frame 6 and is provided with the main drive gear 18, which drives the drive gear 10 and the rotating sleeve 8 to rotate synchronously. The two ends of the rotating sleeve 8 are rotatably set on the inner side of the transverse drive frame 6 through the sleeved bearing parts. The drive gear 10 on the rotating sleeve 8 meshes with the main drive gear 18 on the servo motor B17 to drive the tangent disc 9 to roll and quickly cut the cardboard.

[0027] Specifically, in use, the cut cardboard is first connected to the paper guide roller 3 at the feeding end of the frame 1 using a conveying device. The cut cardboard is then conveyed onto the paper guide roller 3. The paper guide roller 3 is rotated by an external drive motor to rotate and convey the cardboard. Meanwhile, the cylinder 11 pushes the lifting pressure roller 4 downward to lightly press on the surface of the cardboard, keeping the cardboard in a constant conveying position during feeding and preventing conveying deviation that could cause the cutting line to become skewed. During the cutting operation of the cardboard at different transverse intervals, the servo motor A13 drives the transverse drive gear 14 to rotate. The transverse drive gear 14 meshes with the drive rack 15, causing the transverse drive frame 6 to move laterally on the guide rail 5. The transverse drive gear 14 is equipped with a limit switch. With the cooperation of the slot and the limiting strip 16, the transverse drive frame 6 can be adjusted and slid laterally. At the same time, the transverse drive frame 6 drives the rotating sleeve 8 to move laterally on the transverse cylindrical rod 7, thereby driving the cutting disc 9 to move laterally. This allows the cutting discs 9 to slide laterally according to the different spacing widths of the paperboard cutting lines. After the transverse cutting line spacing is adjusted, the servo motor B17 drives the main drive gear 18 to mesh and drive the drive gear 10 to drive the rotating sleeve 8 to rotate on the transverse cylindrical rod 7. At the same time, the cutting disc 9 rotates to roll and cut the paperboard. This allows for rolling cutting of paperboard with different cutting line positions and spacing widths, and shortens the time for changing the cutting template. Moreover, this cutting drive method can speed up the production capacity of paperboard cutting compared to pneumatic cutting.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
