Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard creasing technology, specifically to a corrugated cardboard creasing machine. Background Technology

[0002] Corrugated cardboard is a sheet-like material made by bonding linerboard and corrugated paper formed by corrugating rollers. It is generally divided into single-wall and double-wall corrugated cardboard. Corrugated cardboard has advantages such as low cost, light weight, easy processing, high strength, excellent printability, and convenient storage and handling. It is the main material for manufacturing corrugated boxes. When producing corrugated boxes, the cardboard needs to be folded in half. Because corrugated cardboard is relatively stiff, a creasing machine is often used to crease the fold before folding.

[0003] In the prior art, patent CN222346401 U discloses a corrugated cardboard creasing machine, including a worktable and a top plate. The top plate is fixedly connected to the top surface of the worktable via guide columns, and a lifting plate is provided between the worktable and the top plate. The guide columns pass through the lifting plate and are slidably connected to it. The machine uses a lifting plate and a lifting frame. When creasing the corrugated cardboard, it can be placed on the top surface of the lifting plate. The pressure roller presses the corrugated cardboard under the action of a first spring. When the creasing position is aligned with the upper and lower creasing heads, the electric cylinder extends, pushing the lifting frame and the lower creasing head to move upward. The lower creasing head passes through the through groove and contacts the bottom surface of the corrugated cardboard. As the electric cylinder continues to extend, the corrugated cardboard and the lifting plate move upward synchronously, and the top surface of the corrugated cardboard contacts the upper creasing head. The corrugated cardboard is creasing through the upper and lower creasing heads. In actual operation, the drive motor drives the pressure roller to rotate. The rotation of the pressure roller causes the corrugated cardboard to move on the surface of the lifting plate through friction, thereby pushing the corrugated cardboard to extend the crease area. However, because the pressure roller and the lifting plate are pressed and limited by the first spring and the second spring respectively, it is easy to cause the clamping to be too tight. This causes the contact surface between the pressure roller and the corrugated cardboard to rub repeatedly when rotating, but it cannot drive the corrugated cardboard to move. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model designs a corrugated cardboard creasing machine, which can solve the problem that, under existing technologies, the corrugated cardboard is clamped too tightly, causing repeated friction between the pressure roller and the contact surface of the corrugated cardboard during rotation, but failing to move the corrugated cardboard.

[0010] As a preferred embodiment of this utility model, the limiting frame and the threaded adjusting rod are provided with threaded adjusting holes at corresponding positions. The limiting frame is threadedly connected to the threaded adjusting rod through the threaded adjusting holes. Each of the two sets of limiting frames is provided with a clamping groove on a corresponding side. The clamping groove is rotatably connected to a guide wheel.

[0011] As a preferred embodiment of this utility model, the positioning component is composed of a pull rod, a return spring, and a pressure roller frame.

[0024] In this embodiment, as Figure 2 and Figure 3 As shown, a processing table 103 is fixedly connected above the support platform 1. A movable groove 1031 is provided on the top of the processing table 103 at a position corresponding to the first indentation wheel 1021. A pair of adjustment grooves 104 are provided on the top of the processing table 103 between the feeding rollers 2. A threaded adjustment rod 1041 is rotatably connected to the bottom of the adjustment groove 104. A second motor 1042 is installed at one end of the threaded adjustment rod 1041 outside the adjustment groove 104.

[0025] In this embodiment, as Figure 1 and Figure 2 As shown, a top plate 105 is fixedly connected above the processing table 103, and a second indentation wheel 1051 is rotatably connected to the bottom of the top plate 105 at a position corresponding to the first indentation wheel 1021.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, a pair of feeding rollers 2 are rotatably connected to both sides of the top of the processing table 103. The outer side of each feeding roller 2 is provided with a rubber layer, and anti-slip textures are formed on the outer side of the rubber layer. These anti-slip textures enhance the anti-slip properties and stability of the feeding rollers 2 in contact with the corrugated cardboard. A transmission assembly 201 is installed between the feeding rollers 2 and on one side of the processing table 103. The transmission assembly 201 consists of a third motor 2011, a main gear 2012, a secondary gear 2013, and a transmission belt 2014. A [missing information - likely a device or component] is installed on one side of the left feeding roller 2. The third motor 2011 has a main gear 2012 installed on the side corresponding to the left feeding roller 2, and a secondary gear 2013 installed on the side of the right feeding roller 2. A transmission toothed belt 2014 is sleeved between the main gear 2012 and the secondary gear 2013. The third motor 2011 drives the main gear 2012 to rotate, and drives the secondary gear 2013 to rotate through the transmission toothed belt 2014, thereby simultaneously driving the two sets of feeding rollers 2 to rotate and conveying the corrugated cardboard on the top of the feeding rollers 2.

[0027] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, a limiting frame 3 is slidably connected inside the adjusting groove 104. A threaded adjusting hole 301 is opened at the position corresponding to the threaded adjusting rod 1041 of the limiting frame 3. The second motor 1042 drives the threaded adjusting rod 1041 to rotate, so that the limiting frame 3 slides and moves in the adjusting groove 104 through the threaded adjusting hole 301 and the threaded adjusting rod 1041. This drives the corrugated cardboard in the clamping and limiting to adjust the indentation position. A clamping groove 302 is opened on the corresponding side of each of the two sets of limiting frames 3. A guide wheel 3021 is rotatably connected inside the clamping groove 302. The guide wheel 3021 improves the smoothness of the corrugated cardboard feeding.

The positioning components 4 consist of a pull rod 401, a return spring 402, and a pressure roller frame 403. The pull rod 401 is slidably connected to the top of the top plate 105. The return spring 402 is sleeved on the outside of the pull rod 401 and below the top plate 105. The pressure roller frame 403 is fixedly connected to the bottom of the pull rod 401. The pressure roller is rotatably connected to the bottom of the pressure roller frame 403. The pull rod 401 pulls the pressure roller frame 403 to adjust its height. The return spring 402 pushes the pressure roller frame 403 down through its own elasticity so that the pressure roller is in contact with the top surface of the corrugated cardboard, clamping the corrugated cardboard and improving the stability of the corrugated cardboard conveying.

[0029] In addition, it should be noted that the electric telescopic pole 101 and the motor are both existing technologies, and their internal working principles and operating procedures will not be described in detail here.

[0030] Implementation Plan: First, two sets of limiting frames 3 clamp the corrugated cardboard on both sides using clamping grooves 302. Pull rod 401 pulls the pressure roller frame 403 for height adjustment. Return spring 402, through its own elasticity, pushes the pressure roller frame 403 downwards, causing the pressure roller to press against the top surface of the corrugated cardboard, thus clamping the cardboard and improving the stability of the corrugated cardboard conveying. Second motor 1042 drives the threaded adjusting rod 1041 to rotate, causing the limiting frame 3 to slide and adjust within the adjusting groove 104 through the threaded adjusting hole 301 and the threaded adjusting rod 1041, thereby adjusting the indentation position of the clamped and limited corrugated cardboard. Transmission component 201 uses a third motor 2011 to drive the main gear 2012 to rotate, through transmission... The toothed belt 2014 drives the auxiliary gear 2013 to rotate, thereby simultaneously driving the two sets of feeding rollers 2 to rotate and convey the corrugated cardboard on the top of the feeding rollers 2. The guide wheel 3021 in the adjusting groove 104 improves the smoothness of the corrugated cardboard feeding. The electric telescopic rod 101 pushes the mounting frame 102 to adjust the height, so that the first creasing wheel 1021 lifts the corrugated cardboard and simultaneously creasing the corrugated cardboard with the second creasing wheel 1051. The first motor 1022 drives the first creasing wheel 1021 to rotate and creasing the bottom surface of the corrugated cardboard while assisting in pushing the corrugated cardboard for feeding. The design can improve the smoothness and stability of the corrugated cardboard feeding, facilitate the adjustment of the creasing position, and enhance the overall practicality.
