Description

Technical Field

[0001] This utility model relates to the field of pearl cotton processing technology, and in particular to an automatic slitting device for pearl cotton rolls. Background Technology

[0002] In the modern packaging industry, EPE foam, with its lightweight, excellent cushioning performance, and environmental friendliness, is widely used for packaging and protecting various items such as electronic products, furniture, and ceramics. In practical applications, EPE foam rolls often need to be cut into strips or sheets of different widths according to the dimensions of the packaged items.

[0003] Currently, most EPE foam roll slitting uses traditional slitting equipment, which has problems when adjusting the slitting width. It typically relies on manual adjustment of the slitting blade position. On traditional cardboard slitting machines, the EPE foam slitting blades are usually fixed to the rotating shaft, resulting in a fixed blade position. If different widths of EPE foam need to be cut, the slitting width can only be controlled by adjusting the placement of the EPE foam. However, this method has limitations. For example, when cutting to larger or smaller widths of cardboard, the existing method cannot achieve good slitting results, thus affecting the slitting efficiency of the EPE foam. Therefore, this utility model proposes a novel solution. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide an automatic slitting device for EPE foam rolls. This device can solve the problem that the EPE foam slitting blades on traditional cardboard slitting machines are generally fixed on the rotating shaft. This results in the EPE foam slitting blades having a fixed position. If it is necessary to cut EPE foam into different widths, the slitting width can only be controlled by adjusting the placement of the EPE foam.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic slitting device for pearl cotton rolls, including a pearl cotton slitting device, wherein two connecting shafts are provided between two vertical plates of the pearl cotton slitting device;

[0006] A pearl cotton slitting assembly is mounted on a connecting shaft. The pearl cotton slitting assembly includes a mounting ring that is slidably sleeved on the surface of the connecting shaft. A pearl cotton slitting blade is fixedly sleeved on the outer surface of the mounting ring.

[0007] The inner ring of the mounting ring has four telescopic grooves, and each of the four telescopic grooves has an arc plate slidably connected to it. Each of the four arc plates has a movable push rod fixedly connected to the side away from the connecting shaft. Each of the four movable push rods has a tension spring sleeved on its surface, and the two ends of the four tension springs are fixedly connected between the corresponding arc plate and the inner wall of the telescopic groove.

[0008] The mounting ring has four control chambers located on the outside of the corresponding telescopic grooves. The other ends of the four movable push rods slide through into the corresponding control chambers. Each of the four control chambers has a fixed rotating shaft inside. The outer surfaces of the four rotating shafts are rotatably connected to rotating plates. One side surface of each of the four rotating plates contacts the end of the corresponding movable push rod located inside the control chamber.

[0009] Preferably, the pearl cotton slitting assembly further includes four pull rods. The four pull rods are disposed on the side surface of the four rotating plates away from the corresponding movable push rods. The surface of each of the four rotating plates is provided with a sliding groove. The lower inner side of each of the four pull rods is fixedly connected to a connecting shaft. The four connecting shafts are slidably connected to the corresponding sliding grooves respectively.

[0010] The other ends of the four tie rods slide through the outer surface of the mounting ring, and each of the four tie rods is fixedly connected to a contact rod at the end outside the mounting ring.

[0011] A control ring is slidably fitted onto the outer surface of the mounting ring, and the ends of the four contact rods away from their corresponding pull rods are in contact with the inclined surface of the control ring.

[0012] Preferably, the number of pearl cotton cutting components are multiple sets arranged in a linear array on the surfaces of the two connecting shafts.

[0013] Preferably, the mounting ring and the control ring are fixed together by bolts.

[0014] Preferably, friction plates are fixedly connected to the side of each of the arc-shaped plates near the connecting shaft.

[0015] Preferably, the pearl cotton slitting device is equipped with a drive component. In this solution, the drive component is a drive motor. One end of each of the two connecting shafts rotates through the pearl cotton slitting device and is fixedly connected to the output shafts of the two drive motors respectively.

[0016] Preferably, the pearl cotton slitting device has two pearl cotton conveying rollers between the two vertical plates, and the two pearl cotton conveying rollers are arranged vertically.

[0018] 1. This automatic slitting device for pearl cotton rolls, through the sliding sleeve of the mounting ring on the connecting shaft and the linkage mechanism of the control ring, directly adjusts the axial spacing of the slitting blades, so that the slitting width changes from "the position of the roll adapts to the blade" to "the position of the blade actively adapts to the needs of the roll".

[0028] Please see Figure 1-7This utility model provides a technical solution: an automatic slitting device for EPE foam rolls, including an EPE foam slitting device 1, two connecting shafts 3 between two vertical plates of the EPE foam slitting device 1, and an EPE foam slitting assembly. The EPE foam slitting assembly is mounted on the connecting shafts 3 and includes a mounting ring 4, which is slidably sleeved on the surface of the connecting shafts. An EPE foam slitting blade 5 is fixedly sleeved on the outer surface of the mounting ring 4. The inner ring of the mounting ring 4 has four telescopic grooves 6, and an arc-shaped plate 7 is slidably connected in each of the four telescopic grooves 6. The side of each of the four arc-shaped plates 7 away from the connecting shafts 3 is fixed. The device is connected to four movable push rods 9. Tension springs 10 are sleeved on the surfaces of the four movable push rods 9. The two ends of the four tension springs 10 are fixedly connected between the corresponding arc plate 7 and the inner wall of the telescopic groove 6. Four control cavities 11 are opened in the mounting ring 4. The four control cavities 11 are located on the outside of the corresponding telescopic groove 6. The other ends of the four movable push rods 9 slide through into the corresponding control cavities 11. Rotating shafts 12 are fixedly connected inside each of the four control cavities 11. Rotating plates 13 are rotatably connected to the outer surfaces of the four rotating shafts 12. One side surface of the four rotating plates 13 contacts the end of the corresponding movable push rod 9 located in the control cavity 11.

[0029] The pearl cotton slitting assembly also includes four pull rods 15. The four pull rods 15 are set on the side surface of the four rotating plates 13 away from the corresponding movable push rods 9. The surface of each of the four rotating plates 13 is provided with a sliding groove 17. The lower inner side of each of the four pull rods 15 is fixedly connected to a connecting shaft 18. The four connecting shafts 18 are slidably connected to the corresponding sliding grooves 17. The other end of each of the four pull rods 15 slides through the outer surface of the mounting ring 4. The end of each of the four pull rods 15 located outside the mounting ring 4 is fixedly connected to a contact rod 16. A control ring 14 is slidably sleeved on the outer surface of the mounting ring 4. The end of each of the four contact rods 16 away from the corresponding pull rod 15 contacts the inclined surface of the control ring 14.

[0030] The number of pearl cotton slitting components is multiple, and they are arranged in a linear array on the surfaces of the two connecting shafts 3.

[0031] The mounting ring 4 and the control ring 14 are fixed together by bolts.

[0032] Multiple arc-shaped plates 7 are fixedly connected to friction plates 8 on the side near the connecting shaft 3.

[0033] The pearl cotton slitting equipment 1 is equipped with a drive component. In this solution, the drive component is a drive motor. One end of each of the two connecting shafts 3 is rotated through the pearl cotton slitting equipment 1 and is fixedly connected to the output shafts of the two drive motors respectively.

[0034] The pearl cotton slitting equipment 1 has two pearl cotton conveying rollers 2 between the two vertical plates, and the two pearl cotton conveying rollers 2 are arranged vertically up and down.

[0035] When using this device, a vertically distributed pearl cotton conveying roller 2 is set between the two vertical plates of the pearl cotton slitting equipment 1 to clamp and convey the pearl cotton roll; the drive component (drive motor) inside the equipment drives the two connecting rotating shafts 3 to rotate synchronously through the output shaft, thereby driving the pearl cotton slitting component installed on the connecting rotating shaft 3 to rotate at high speed, so as to realize the slitting of the pearl cotton roll.

[0036] Multiple pearl cotton slitting components are arranged in a linear array on the surface of the connecting shaft 3. The mounting ring 4 is slidably sleeved on the connecting shaft 3. The pearl cotton slitting blade 5 is fixedly sleeved on the outside, and the position is fixed and adjusted on the inside through structures such as the telescopic groove 6 and the arc plate 7. The control ring 14 is slidably sleeved on the outside of the mounting ring 4 and fixed to the mounting ring 4 by bolts, and is used to adjust the position of the slitting blade in linkage.

[0037] When the cutting width needs to be adjusted, loosen the fixing bolts between the mounting ring 4 and the control ring 14, and manually push or pull the control ring 14 to slide along the outer surface of the mounting ring 4; the inner inclined surface of the control ring 14 contacts the contact rod 16, pushing the contact rod 16 to move outward.

[0038] The contact rod 16 drives the pull rod 15 to move horizontally. The pull rod 15 slides in the groove 17 of the rotating plate 13 through the inner connecting shaft 18, forcing the rotating plate 13 to rotate around the rotating shaft 12. When the rotating plate 13 rotates, it squeezes the movable push rod 9, pushing the arc plate 7 to move towards the center of the connecting shaft 3 and compressing the tension spring 10. The friction plate 8 on the inner side of the arc plate 7 contacts the surface of the connecting shaft 3, and fixes the axial position of the mounting ring 4 through friction, thereby adjusting the spacing of the slitting blade 5 on the connecting shaft 3 and achieving precise adjustment of the slitting width.

[0039] After adjustment, tighten the fixing bolts of the control ring 14 and the mounting ring 4 to ensure the stability of the blade position during the cutting process by mechanical locking; if reset is required, after loosening the bolts, the elastic force of the tension spring 10 will drive the arc plate 7 to reset, so that the mounting ring 4 can slide freely.

[0040] The EPE foam roll is conveyed forward by the friction of the upper and lower EPE foam conveying rollers 2, ensuring that the roll enters the slitting area flat; the connecting shaft 3 drives the slitting blades 5 to rotate at high speed, and cuts the roll laterally according to the pre-adjusted blade spacing to form EPE foam strips or sheets of a specified width; the combination of the arc plate 7 and the friction plate 8 fixes the mounting ring 4 through multi-point contact pressure, avoiding the blade offset problem caused by single-point fixing in traditional manual adjustment; the linearly arrayed multi-group slitting components can complete multiple slitting simultaneously, improving production efficiency while ensuring that the width of each slitting path is consistent.

[0041] Furthermore, by sliding the mounting ring 4 onto the connecting shaft 3 and cooperating with the linkage mechanism of the control ring 14, the axial spacing of the slitting blades 5 can be directly adjusted, so that the slitting width changes from "the position of the roll adapts to the blade" to "the position of the blade actively adapts to the needs of the roll". This completely solves the limitations of the traditional method when slitting in large or small widths, improves the practicality and convenience of the device, and increases the slitting efficiency of the device.
