Description

Technical Field

[0001] This utility model relates to the field of latex sheet production technology, and more specifically, to a slitting device for latex sheet production. Background Technology

[0002] Latex sheets are made from natural or synthetic latex. Generally, thick latex sheets are cut into thin sheets by a slitting device for use in the latex layer of spring mattresses. The cold-blade single-blade latex cutter includes a frame, a drive assembly, and a cutting blade. The drive assembly moves the cutting blade horizontally to cut the thick latex sheet into thin sheets. Because latex has high elasticity and flexibility, it is easy to deform or shift during cutting, so it needs to be used with a clamp. Existing clamps are generally driven by the drive assembly and clamp the thick latex sheet at both ends.

[0003] In existing latex sheet production slitting devices, the clamps cannot move with the cutting blade when slitting thick latex sheets. When the cutting blade cuts to the middle of the thick latex sheet, the middle of the thick latex sheet is prone to bounce or displacement, resulting in a decrease in cutting accuracy. In view of this, we propose a slitting device for latex sheet production. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the actual needs, and provide a slitting device for latex sheet production, so as to solve the technical problem that the middle part of the thick latex sheet is prone to bounce or displacement during the slitting operation, resulting in a decrease in cutting accuracy.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a slitting device for latex sheet production, including a worktable, a first lead screw displacement drive assembly installed on one side of the worktable, a fixed frame connected to the power output end of the first lead screw displacement drive assembly, a second lead screw displacement drive assembly fixedly installed at one top end of the fixed frame, and a cutting assembly connected to the power output end of the second lead screw displacement drive assembly, characterized in that a following clamp is slidably installed at the other top end of the fixed frame, the following clamp including a top clamp, and side clamps slidably connected to both sides of the top clamp;

[0006] The top clamping component includes a top clamping frame, and two sets of triangular blocks are symmetrically installed at both ends of the top of the top clamping frame, with the inclined surfaces of the triangular blocks facing each other.

[0007] The side clamp includes two side clamping strips that are symmetrically distributed to form an "eight" shape. A sliding strip is fixedly connected to the top of the side clamping strip, and a counterweight frame is slidably connected to the outside of the sliding strip. The counterweight frame is connected to the inclined end of the top of the triangular block.

[0008] Preferably, the cutting assembly includes a cutting blade, one end of which is mounted on the power output end of the second lead screw displacement drive assembly, and the other end of which is mounted with an end slide, which is slidably connected to the other side of the worktable.

[0009] Preferably, the top clamping frame has sliding grooves at both ends, and the triangular blocks are distributed outside the sliding grooves.

[0010] Preferably, the slide bar is slidably connected within the slide groove, and a top plate is fixedly connected to the top of the slide bar.

[0011] Preferably, the side clamps, slides, and top plate are all made of lightweight materials, while the counterweight frame is made of heavy-duty materials.

[0012] Preferably, the two side clamping strips are rotatably connected to each other by a plurality of first ball bearings, and the top of the top clamping frame is rotatably connected to a plurality of second ball bearings.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The cutting end of the cutting component of this utility model is equipped with a following clamp via a fixed frame, which can follow and press the latex sheet. During the following movement, the top clamp can press the top of the latex sheet with its own weight, while the counterweight frame slides down the inclined surface of the top of the triangular block. The side clamps at both ends converge towards the middle to clamp the two ends of the latex sheet. The side clamps and the top clamp are both equipped with rotating ball bearings facing the latex sheet surface, which can follow the movement more smoothly and reduce the frictional resistance during the following movement. This solves the problem that the middle of the latex sheet is prone to bounce or displacement during the cutting operation of the existing latex sheet production slitting device, which leads to a decrease in cutting accuracy.

[0015] 2. This utility model also designs two symmetrically distributed side clamping strips at both ends of the latex sheet to form an "eight"-shaped structure, which enables the latex sheet to slide more smoothly from the end to the latex sheet and press the latex sheet tightly from both sides. This further solves the problem that the middle part of the latex sheet is prone to bounce or displacement during the cutting operation of the existing latex sheet production slitting device, which leads to a decrease in cutting accuracy.

[0024] like Figures 1 to 4 As shown, the present invention relates to a slitting device for latex sheet production, comprising a worktable 1, a first lead screw displacement drive assembly 2 installed on one side of the worktable 1, a fixed frame 4 connected to the power output end of the first lead screw displacement drive assembly 2, a second lead screw displacement drive assembly 3 fixedly installed at one top end of the fixed frame 4, and a cutting assembly 5 connected to the power output end of the second lead screw displacement drive assembly 3. The device is characterized in that a follower clamp 6 is slidably installed at the other top end of the fixed frame 4, the follower clamp 6 including a top clamp 8, and side clamps 7 slidably connected to both sides of the top clamp 8.

[0025] The top clamp 8 includes a top clamp frame 801, and two sets of triangular blocks 803 are symmetrically installed at both ends of the top of the top clamp frame 801, with the inclined surfaces of the triangular blocks 803 facing each other.

[0026] The side clamp 7 includes two side clamping strips 701, which are symmetrically distributed to form a figure-eight shape. A slide bar 702 is fixedly connected to the top of the side clamping strip 701, and a counterweight frame 703 is slidably connected to the outside of the slide bar 702. The counterweight frame 703 is connected to the top inclined end of the triangular block 803. The cutting end of the cutting assembly 5 of this utility model is followed by a follower clamp 6 installed through a fixing frame 4, which can follow and press the latex sheet. During the follower movement, the top clamp 8 can press the top of the latex sheet by its own weight. At the same time, the counterweight frame 703 slides down the top inclined surface of the triangular block 803, and the side clamps 7 at both ends converge towards the middle to clamp the two ends of the latex sheet. The side clamps 701 and the top clamp frame 801 are both equipped with ball bearings that rotate towards the latex sheet surface, which can follow the movement more smoothly and reduce the frictional resistance during the following movement. In addition, by designing two symmetrically distributed side clamps 701 at both ends of the latex sheet to form an "eight" shape, it is possible to slide more smoothly from the end of the latex sheet onto the latex sheet and press the latex sheet from both sides.

[0027] Furthermore, the cutting assembly 5 includes a cutting blade 501. One end of the cutting blade 501 is installed at the power output end of the second lead screw displacement drive assembly 3, and the other end of the cutting blade 501 is equipped with an end slide 502. The end slide 502 is slidably connected to the other side of the worktable 1, and the end slide 502 can make the cutting blade 501 move more smoothly.

[0028] Furthermore, both ends of the top of the top clamping frame 801 are provided with sliding grooves 802, and triangular blocks 803 are distributed outside the sliding grooves 802, so that the side clamping piece 7, under its own weight, slides along the top slope of the triangular block 803 in the sliding groove 802 towards the center, and abuts against both sides of the latex sheet.

[0029] Furthermore, the slider 702 is slidably connected within the slide groove 802, and a top piece 704 is fixedly connected to the top of the slider 702, providing excellent limiting effect.

[0030] Furthermore, the side clamping strip 701, the sliding strip 702, and the top plate 704 are all made of lightweight materials, while the counterweight pressure frame 703 is made of heavy materials. When the counterweight pressure frame 703 slides down the top slope of the triangular block 803, it can squeeze the side clamping strip 701, the sliding strip 702, and the top plate 704 as a whole towards the sides of the latex sheet and press against the sides of the latex sheet.

[0031] Furthermore, the two side clamping strips 701 are rotatably connected to each other with a number of first ball bearings 705, and the top of the top clamping frame 801 is rotatably connected to a number of second ball bearings 804, which can make the movement smoother and reduce the frictional resistance when following the movement.

[0032] Working Principle: This embodiment provides a slitting device for latex sheet production. In use, the cutting end of the cutting component 5 is mounted with a following clamp 6 via a fixing frame 4. This clamp 6 can follow and press the latex sheet. During the following movement, the top clamp 8 can press against the top of the latex sheet by its own weight. Simultaneously, the counterweight frame 703 slides down the inclined surface at the top of the triangular block 803. The side clamps 7 at both ends synchronously converge towards the center to clamp the two ends of the latex sheet. Furthermore, both the side clamping strips 701 and the top clamping frame 801 face the surface of the latex sheet. The rotating assembly features ball bearings for smoother following and reduced frictional resistance. Two symmetrically distributed "V"-shaped side clamps 701 at both ends of the latex sheet facilitate smoother sliding from the end onto the sheet and press it firmly from both sides. A following clamp 6 is slidably mounted on the other end of the top of the fixing frame 4. The following clamp 6 is manually lifted and moved upwards, causing the top clamp frame 801 to press against the top of the latex sheet to be sliced. The top clamp 8, under its own weight,... Pressed on top of the latex sheet, and with two symmetrically distributed side clamps 701 at both ends of the latex sheet forming an "eight" shape, the side clamps 7 can slide more smoothly from the ends of the latex sheet onto the latex sheet during movement. When the counterweight frame 703 slides down the top slope of the triangular block 803, it can squeeze the side clamps 701, slide bars 702, and top plate 704 together towards the sides of the latex sheet. The slide bars 702 slide within the slide groove 802, and the two sets of side clamps 701, slide bars 702, and top plate 704 together... The body abuts against the thick latex sheet from both sides. During the cutting process of the cutting component 5, the follower clamp 6 can move with the cutting component 5. Several first ball bearings 705 are rotatably connected to the opposite surfaces of the two side clamping bars 701. Several second ball bearings 804 are rotatably connected to the top of the top clamping frame 801. This allows for smoother following and movement outside the thick latex sheet, reducing frictional resistance during following and movement (the first lead screw displacement drive component 2 and the second lead screw displacement drive component 3 are both existing products on the market and are both connected to external switches and external power sources).

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
