Description

Technical Field

[0001] This utility model relates to the technical field of cross-cutting machines, and in particular to a cutting blade lubrication structure for a cross-cutting machine. Background Technology

[0002] A cross-cutting machine is one of the machines used in corrugated cardboard processing. In a corrugated cardboard production line, the cross-cutting machine is a specialized piece of machinery for cutting finished cardboard, enabling the corrugated cardboard to meet subsequent cardboard box manufacturing processes. Currently, cross-cutting machines generally cut the cardboard through the reciprocating motion of the cutter. The constant contact and friction between the cutter and the cardboard causes the cutter temperature to rise and can easily lead to cutter edge jerking and damage. Therefore, it is necessary to frequently lubricate the cutters on the cross-cutting machine and provide cooling protection to extend their service life. Existing lubrication mechanisms usually require manual intervention during the start-up and shutdown of the cross-cutting machine, making it difficult to perform timed lubrication of the cutters.

[0003] Chinese Patent Publication No. CN216031194U, published on March 15, 2022, discloses a lubrication mechanism for a cross-cutting machine cutter. The mechanism includes a supporting base plate, characterized by two symmetrically arranged lubrication mechanisms on the upper part of the base plate, each with an oiling mechanism at its bottom end. Connecting members are symmetrically fixed to both sides of the base plate. Each lubrication mechanism includes two lubrication rollers, parallel and spaced apart above the base plate. Supporting mechanisms are rotatably mounted at both ends of each roller, and these mechanisms are fixedly connected to the base plate. The drawback of this invention is that the lubrication mechanism requires manual contact with the cutter for lubrication, making timed lubrication difficult. Utility Model Content

[0004] This invention aims to overcome the shortcomings of existing technologies in achieving timed lubrication of cross-cutting machines by providing a cutter lubrication structure for cross-cutting machines that can automatically perform intermittent lubrication of the cutter.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cutting blade lubrication structure for a cross-cutting machine, comprising: Cutting knife holder; A bonding assembly, which is mounted on a cutter holder; A lubrication assembly, wherein the lubrication assembly is mounted on the fitting assembly and slidably connected to the cutter holder; An intermittent assembly is mounted on a cutter holder and is in contact with a bonding assembly.

[0006] The cutter holder is the main structure of the cross-cutting machine. A lubrication device is installed on the cutter holder, and the bonding component is mounted on the cutter holder and can rotate. The bonding component can drive the lubrication component to bond with the cutter on the cutter holder, thus lubricating the cutter. An intermittent component is also installed on the cutter holder. The intermittent component controls whether the bonding component is bonded with the cutter. By controlling the rotation of the bonding component, the lubrication device and the cutting process are coordinated. By controlling the bonding component to bond with the cutter at regular intervals, the purpose of automatically intermittently lubricating the cutter is achieved.

[0007] Preferably, the cutter holder is equipped with a cutter, which is slidably connected to the cutter holder. An mounting frame is installed on the cutter holder, and fitting components are installed on both sides of the mounting frame. Each fitting component includes a rotating rod and a mounting rod. Two rotating rods are provided and respectively installed at both ends of the mounting frame. The two ends of each mounting rod are connected to rotating rods at both ends of the mounting frame. A paper cutter is installed on the cutter holder. A pneumatic cylinder drives the cutter to move up and down on the cutter holder, cutting the paper. An mounting frame is installed on the cutter holder, and fitting components are installed on the mounting frame. The two rotating rods of the fitting components are rotatably connected to both ends of the mounting frame. The rotating rods drive the connected mounting rods to move, bringing the rods closer to the cutter for fitting. During the rotation of the rotating rods and the movement of the mounting rods, to ensure horizontal movement of the mounting rods, the mounting rods are slidably connected to the rotating rods at both ends. When the rotating rods push the mounting rods to move, the mounting rods can slide on the rotating rods to adjust their position. This design facilitates fitting with the cutter.

[0008] Preferably, the lubrication assembly includes a storage tank and an absorber block. The storage tank is mounted on and rotatably connected to a mounting rod. The storage tank has a storage cavity on the side facing the cutter. A feeding pipe is installed on the storage tank and communicates with the storage cavity. The absorber block is installed inside the storage cavity and corresponds to the cutter. The lubrication assembly is mounted on the mounting rod, and the storage tank is rotatably connected to the mounting rod. During the movement of the mounting rod, the lubrication assembly faces the cutter for lubrication. Lubricating fluid is introduced into the storage cavity of the storage tank through the feeding pipe. The absorber block, installed at the open end of the storage cavity, absorbs the lubricating fluid and lubricates the cutter by adhering to the cutter. The absorber block seals the open end of the storage cavity, ensuring that the lubricating fluid can only be absorbed through the absorber block. This design effectively lubricates the cutter.

[0009] Preferably, a limiting plate is installed on the cutter holder. The limiting plate has two sides and is respectively placed on the upper and lower sides of the storage box, and the limiting plate is in contact with the storage box. During the movement of the storage box by the mounting rod, it is necessary to ensure the orientation of the storage box. To ensure that the absorber block faces the cutter and moves in the opposite direction, a limiting block is installed on the cutter holder. The limiting plate, which is in contact with the upper and lower sides of the storage box, restricts the movement of the storage block. This design limits the direction of movement of the storage box.

[0010] Preferably, the intermittent assembly includes a motor, a motor mount is installed on one side of the cutter holder, the motor is mounted on the motor mount, and a cam is mounted on the motor shaft of the motor. The two sides of the cam are respectively in contact with the rotating rods of the two side-mounted components. The motor of the intermittent assembly is mounted on the motor mount on the cutter holder. The cam, with an elliptical cross-section, is mounted on the motor shaft of the motor and can move simultaneously with the rotating rods on both sides. The rotation of the cam compresses the rotating rods on both sides, causing them to rotate. The cam drives the reciprocating motion of the rotating rods, thus controlling the intermittent movement of the rotating rods.

[0011] Preferably, a tension spring is provided on the other side of the cutter holder, and the two ends of the tension spring are respectively connected to the rotating rods of the two side contact components. Although the rotating rod can contact the cam under its own weight, the rotating rod is not stable enough. Therefore, a tension spring is installed on the rotating rod, and the two ends of the tension spring are connected to the rotating rods on both sides. The tension spring pulls the rotating rod to rotate inward, thereby contacting the cam. This design can ensure that the rotating rod contacts the cam.

[0012] The beneficial effects of this utility model are: it can automatically perform intermittent lubrication on the cutter, making it easy to fit with the cutter; it can lubricate the cutter; it can limit the movement direction of the storage box; it can control the intermittent movement of the rotating rod; and it can ensure that the rotating rod fits with the cam.

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1 In the illustrated embodiment, the cutting blade lubrication structure of the cross-cutting machine includes: Cutting holder 1; Adhesion component 2 is mounted on the cutter holder 1; Lubrication component 3 is installed on fitting component 2 and slidably connected to cutter holder 1; Intermittent component 4 is mounted on the cutter holder 1 and is in contact with the bonding component 2.

[0017] like Figure 2 , Figure 3 As shown, a cutter 11 is provided on the cutter holder 1, and the cutter 11 is slidably connected to the cutter holder 1. An installation frame 12 is installed on the cutter holder 1, and a bonding component 2 is installed on both sides of the installation frame 12. The bonding component 2 includes a rotating rod 21 and a mounting rod 22. There are two rotating rods 21, which are respectively installed at both ends of the installation frame 12. The two ends of the mounting rod 22 are respectively connected to the rotating rods 21 at both ends of the installation frame 12.

[0018] like Figure 4 , Figure 5 As shown, the lubrication assembly 3 includes a storage box 31 and an absorption block 32. The storage box 31 is mounted on the mounting rod 22 and is rotatably connected to the mounting rod 22. The storage box 31 has a storage cavity 33 on the side facing the cutter 11. A feeding pipe 34 is installed on the storage box 31 and communicates with the storage cavity 33. The absorption block 32 is installed in the storage cavity 33 and corresponds to the cutter 11.

[0019] A limiting plate 13 is installed on the cutter holder 1. The limiting plate 13 has two sides and is placed on the upper and lower sides of the storage box 31 respectively. The limiting plate 13 is in contact with the storage box 31.

[0020] like Figure 6As shown, the intermittent component 4 includes a motor 41, a motor mount 42 is mounted on the side of the cutter holder 1, the motor 41 is mounted on the motor mount 42, a cam 43 is mounted on the motor shaft of the motor 41, and the two sides of the cam 43 are respectively attached to the rotating rod 21 of the two side attachment components 2.

[0021] A tension spring 23 is provided on the other side of the cutter holder 1. The two ends of the tension spring 23 are respectively connected to the rotating rods 21 of the two side fitting components 2.

[0022] During the cutting process of the cutter 11 moving up and down on the cutter holder 1, the motor 41 drives the cam 43 to rotate. The rotating rod 21 installed on the mounting frame 12 is pulled by the tension spring 23 and fits against the cam. The rotation of the cam 43 squeezes the rotating rods 21 on both sides to separate and move away from the cutter 11. At this time, the cutter 11 descends to cut the cardboard.

[0023] During the continuous cutting process, motor 41 continues to drive cam 43 to rotate. The short shaft of cam 43 is in contact with rotating rod 21. At this time, the rotating rods 21 on both sides approach each other, and the rotating rods 21 drive the mounting rod 22 to move towards the cutter 11. The mounting rod 22 pushes the storage box 31 to move together until the absorbent block 32 installed on the storage box 31 corresponds to the cutter 11. At this time, the cutter 11 descends and contacts the absorbent block 32 through its lower end. The absorbent block 32 lubricates the cutter by absorbing the lubricating fluid in the storage cavity 31. Through the continuous rotation of cam 43, the rotating rod 21 is driven to reciprocate, thereby pushing the lubrication component 3 to intermittently approach the cutter 11 for lubrication.
