Description

Technical Field

[0001] The utility model relates to the technical field of dust-free paper cutting, in particular to a positioning mechanism of a dust-free paper cutting device. Background Art

[0002] Dust-free paper is also called dry-laid nonwoven fabric, which is a type of dry-laid nonwoven fabric. Dust-free paper has unique physical properties, such as high elasticity, softness, excellent hand feel and drape, high water absorption and good water retention, and is widely used in sanitary care products, special medical products, industrial wiping products and other fields.

[0003] Some of the dust-free papers after manufacturing are too large in size and need to be cut by a cutting device to cut them into suitable sizes for use. However, most cutting devices cut by quickly dropping a cutting knife, and hundreds of sheets of paper are cut at the same time. If only a few sheets of paper are cut, there is no positioning mechanism, which means that the paper cannot be cut in a taut state and may be blown away, resulting in cutting deviations. If you use both hands to hold it, it consumes a lot of energy and the cutting efficiency is low. Utility Model Content

[0009] In addition, a preferred structure is that a movable cavity is opened in the outer wall inside the adjustment seat and located on one side of the cutting knife, the fixed block moves up and down in the movable cavity, a traction cavity is connected to the upper end of the movable cavity, an adjustment cavity is connected to one side of the traction cavity, and the adjustment cavity is located on the outer wall on the other side of the adjustment seat.

[0010] In addition, a preferred structure is that a traction rope is arranged in the traction cavity, rollers are symmetrically arranged in the upper end cavity of the traction cavity, and the traction rope is placed on the rollers.

[0011] In addition, a preferred structure is that one end of the traction rope is fixedly connected to the middle of the upper surface of the connecting block, and the other end of the traction rope is fixedly connected to the wave block, and the wave block moves up and down in the regulating cavity.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-6 A positioning mechanism for a dust-free paper cutting device comprises a cutting device 1, wherein the cutting device 1 comprises a cutting platform 2, a fixing frame 4 is vertically fixed to one side of the upper surface of the cutting platform 2, a pneumatic lifting device 6 is installed on the upper end of the fixing frame 4, an adjusting seat 3 is vertically fixed to the other side of the upper surface of the cutting platform 2, and a positioning mechanism 5 is installed in the adjusting seat 3;

[0025] The positioning mechanism 5 includes a positioning plate 51, a cavity is opened in the middle of the positioning plate 51, a sponge pad 52 is attached to the lower surface of the positioning plate 51, a fixing block 53 is fixedly connected to one side of the positioning plate 51, pulleys 54 are symmetrically arranged on the outer walls of both sides of the fixing block 53, a connecting block 55 is fixedly connected to the middle part of the tail end of the fixing block 53, and the fixing block 53 moves up and down in the adjustment seat 3.

[0026] Among them, a cutting knife 7 is installed at the bottom lifting end of the pneumatic lifting device 6, and a positioning mechanism 5 is arranged below the cutting knife 7. The cutting knife 7 can pass through the cavity of the positioning plate 51. The cutting knife 7 is easy to cut the dust-free paper under the drive of the pneumatic lifting device 6.

[0027] In addition, a movable cavity 31 is opened in the outer wall of the adjusting seat 3 and located on the side of the cutting knife, and the fixed block 53 moves up and down in the movable cavity 31. A traction cavity 32 is opened at the upper end of the movable cavity 31, and an adjustment cavity 33 is opened on one side of the traction cavity 32. The adjustment cavity 33 is located on the outer wall on the other side of the adjusting seat 3. A traction rope 10 is arranged in the traction cavity 32, and rollers 11 are symmetrically arranged in the upper end cavity of the traction cavity 32. The traction rope 10 is placed on the roller 11, and the rolling of the roller 11 facilitates the smooth traction and pulling of the traction rope 10.

[0028] Moreover, one end of the traction rope 10 is fixedly connected to the middle of the upper surface of the connecting block 55, and the other end of the traction rope 10 is fixedly connected to the wave block 8. The wave block 8 moves up and down in the adjusting cavity 33, which is convenient for pulling the traction rope 10.

[0029] At the same time, a movable opening 311 is provided at the outer wall of the movable cavity 31 connected to the adjustment seat 3, sliding grooves 312 are symmetrically provided on both sides of the movable cavity 31, and a groove 313 is provided at the rear end of the movable cavity 31, and the upper end of the groove 313 is connected to the traction cavity 32. A pulley 54 is placed in the sliding groove 312, and the connecting block 55 moves up and down in the groove 313. The pulley 54 is set to slide in the sliding groove 312, so that the fixed block 53 can move up and down.

[0030] Moreover, a spring 9 is arranged in the movable cavity 31, the top end of the spring 9 is fixed on the top wall of the movable cavity 31, and the bottom end of the spring 9 is fixedly connected to the middle part of the upper surface of the fixed block 53. Under the elastic contraction of the spring 9, the fixed block 53 can be quickly reset after being pulled by the fixed block 53 once there is no external force, so that the positioning plate 51 presses the dust-free paper.

[0031] In this embodiment, when using the cutting device 1 to cut dust-free paper, when only a few sheets of paper need to be cut, the paper is placed on the cutting platform 2. At this time, because the positioning mechanism 5 is pressed on the upper surface of the cutting platform 2, the positioning mechanism 5 must first be pulled up, and the wave block 8 on the wave adjustment seat 3 is pulled up.

[0032] First, pull the wave block 8 downward. Under the action of external force, the wave block 8 moves downward in the adjustment cavity 33. The wave block 8 pulls the traction rope 10. With the cooperation of the rotation of the roller 11, the traction rope 10 moves in the traction cavity 32. At the same time, pull the connecting block 55 in the groove 313 to make the connecting block 55 move upward. Cooperate with the pulley 54 to slide in the sliding groove 312, so that the fixed block 53 can move upward in the movable cavity 31. Then, the positioning plate 51 connected to the fixed block 53 through the movable opening 311 also moves upward. At this time, the positioning plate 51 no longer fits the upper surface of the cutting platform 2.

[0033] Then the dust-free paper is passed through the gap between the positioning plate 51 and the cutting platform 2. After the position of the dust-free paper cutting is adjusted, the wave block 8 is loosened. At this time, because the fixed block 53 is not pulled by the traction rope 10, the spring 9 pushes the fixed block 53 downward due to its elastic contraction force, so that the fixed block 53 drives the positioning plate 51 to squeeze the dust-free paper, which plays a positioning role, can fix the dust-free paper and is in a taut state, which is convenient for the cutting knife 7 to cut.

[0034] Finally, the pneumatic lifting device 6 drives the cutting knife 7 to pass through the cavity of the positioning plate 51 to cut the dust-free paper.

[0035] In the utility model, a positioning mechanism 5 is arranged on the cutting device 1, which is used to position the dust-free paper. The traction rope 9 is pulled by pulling the wave block 8 on the adjustment seat 3. The traction rope 9 cooperates with the rotation of the roller 11 to effectively pull up the fixed block 53. This adjustment method makes it faster to pull up the positioning mechanism 5. After the wave block 8 is sent away, the elastic contraction force of its spring 9 causes the spring 9 to push the fixed block 53 downward, so that the fixed block 53 drives the positioning plate 51 to squeeze the dust-free paper, which plays a positioning role. The dust-free paper can be fixed and is in a taut state, which is convenient for the cutting knife 7 to cut. There is no need to hold the dust-free paper with both hands. The positioning mechanism 5 is required to fix it, which effectively improves the cutting efficiency.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
