Description

Technical Field

[0001] This utility model relates to the field of self-adhesive label technology, specifically a label cutter. Background Technology

[0002] Self-adhesive labels have advantages over traditional labels, such as no need for glue, paste, or water, no pollution, and saving labeling time. They have a wide range of applications and are convenient and quick. Self-adhesive labels are a type of material, also called self-adhesive label material. They are composite materials with paper, film or other special materials as the face stock, adhesive on the back, and silicone-coated release paper as the backing paper. After printing, die-cutting and other processing, they become finished labels. Self-adhesive label tapes usually need to be cut to a certain length and then rolled up for transportation.

[0003] Currently, since the width of the aforementioned rolls of self-adhesive labels is fixed, such a large width is often not needed in actual use, resulting in waste of self-adhesive labels. However, existing technologies lack equipment that can cut the width of self-adhesive labels, and most cutting is done manually, which is extremely inconvenient. Therefore, a label cutter that can automatically cut rolls of self-adhesive labels into smaller widths is proposed to solve the above problems. Utility Model Content

[0004] To overcome the technical deficiencies in the prior art and effectively solve the technical problems in the background art, this utility model provides the following technical solution:

[0005] A label cutter includes a housing. The lower parts of the front and rear sides of the housing are symmetrically provided with cutting grooves for label cutting. A fixed shaft is fixedly installed on the rear part of the left and right inner walls of the housing, and a blade is rotatably connected to the fixed shaft. A pressure shaft for pressing and limiting the blade is slidably connected to the middle of the left and right inner walls of the housing via a sliding groove. A second sliding groove, corresponding to the first sliding groove and slidably connected to the outer side of the pressure shaft, is provided on the side of the blade. An mounting rod is fixedly installed on the front part of the left and right inner walls of the housing. Torsion springs are symmetrically sleeved on the left and right ends of the mounting rod. A pressure rod for elastically pressing the pressure shaft is integrally provided on the outer ends of the two torsion springs. A U-shaped bracket is integrally provided on the inner ends of the two torsion springs, contacting and pressing against the upper front surface of the housing. A pressure adjustment component for adjusting the pressure is provided on the U-shaped bracket.

[0006] As a preferred technical solution of this utility model, the pressure regulating assembly includes an adjusting plate, a threaded sleeve, a threaded rod, and a knob. The adjusting plate is fixedly installed between the two arms of the U-shaped bracket at a position inside the housing cavity. A threaded sleeve corresponding to the front and rear of the adjusting plate is provided on the front side of the housing. A threaded rod is threadedly connected to the threaded sleeve. The rear end of the threaded rod abuts against the front side of the adjusting plate, and a knob is fixedly installed on the front end of the threaded rod.

[0007] As a preferred embodiment of this utility model, the shell is a transparent shell.

[0008] As a preferred embodiment of this invention, the bottom cutting edge of the blade is an arc-shaped cutting edge.

[0009] As a preferred embodiment of this invention, the bottom of the pressure rod contacts and presses against one side of the upper surface of the pressure shaft.

[0010] As a preferred embodiment of this utility model, the two arms of the U-shaped bracket are integrally connected to the inner ends of the two torsion springs respectively.

[0011] As a preferred technical solution of this utility model, the first slide is a "7" shaped structure with the horizontal end being higher at the front and lower at the back.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by passing one end of the roll of self-adhesive labels through two cutting slots from back to front and pulling the front end of the self-adhesive label roll, the blade can automatically cut the width of the self-adhesive label during the pulling process under the pressure of the mounting rod and torsion spring, quickly and conveniently sliding and cutting it into a smaller width; through the pressure adjustment component, the cutting pressure of the blade can be adjusted to facilitate cutting labels of different thicknesses, or to perform single-layer cutting of the label paper (without cutting the bottom protective paper) or double-layer cutting of the label paper plus the bottom protective paper (cutting the bottom protective paper); therefore, the cutting is more convenient and conducive to the economical use of self-adhesive labels.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a label cutter, including a housing 1. The lower parts of the front and rear sides of the housing 1 are symmetrically provided with cutting grooves 2 for label cutting. A fixed shaft 3 is fixedly installed on the rear part of the left and right inner walls of the housing 1. A blade 6 is rotatably connected to the fixed shaft 3. A pressure shaft 4 for pressing and limiting the blade 6 is slidably connected to the middle part of the left and right inner walls of the housing 1 via a sliding groove 5. A second sliding groove 7, corresponding to the sliding groove 5 and slidably connected to the outer side of the pressure shaft 4, is provided on the side of the blade 6. An installation rod 8 is fixedly installed on the front part of the left and right inner walls of the housing 1. Torsion springs 9 are symmetrically sleeved on both ends of the installation rod 8. A pressure rod 12 for elastically pressing the pressure shaft 4 is integrally provided on the outer ends of the two torsion springs 9. A U-shaped bracket 10 is integrally provided on the side end, which contacts and presses against the upper front surface of the housing 1. A pressure adjustment component 11 for adjusting pressure is provided on the U-shaped bracket 10. In use, by passing one end of the roll of self-adhesive label through the two cutting slots 2 from back to front and pulling the front end of the self-adhesive label roll, the blade 6 can automatically cut the width of the self-adhesive label during the pulling process under the pressure of the mounting rod 8 and the torsion spring 9, quickly and conveniently sliding and cutting it into a smaller width. The cutting pressure of the blade 6 can be adjusted by the pressure adjustment component 11 to facilitate cutting labels of different thicknesses, or to perform single-layer cutting of label paper (without cutting the bottom protective paper) and double-layer cutting of label paper plus bottom protective paper (cutting the bottom protective paper).

[0020] Furthermore, such as Figure 3 and 4As shown, the pressure regulating assembly 11 includes an adjusting plate 111, a threaded sleeve 112, a threaded rod 113, and a knob 114. The adjusting plate 111 is fixedly installed between the two arms of the U-shaped bracket 10 in the inner cavity of the housing 1. The front side of the housing 1 has a threaded sleeve 112 corresponding to the front and rear of the adjusting plate 111. The threaded sleeve 112 is threadedly connected to the threaded rod 113. The rear end of the threaded rod 113 abuts against the front side of the adjusting plate 111. The front end of the threaded rod 113 is fixedly installed with a knob 114. In use, by turning the knob 114, the threaded rod 113 is rotated back and forth, which allows the threaded rod 113 to slide up and down on the front side of the adjusting plate 111. This, in turn, causes the adjusting plate 111 and the U-shaped bracket 10 to rotate and move, thereby causing the pressure rod 12 to generate pressure on the pressure shaft 4 and causing it to slide in the first slide groove 5 and the second slide groove 7. This facilitates the adjustment of the cutting pressure of the blade 6 as needed.

[0021] Furthermore, the housing 1 can be a transparent housing made of plastic or glass, which makes it easy to observe the inside of the housing 1 during use.

[0022] Furthermore, such as Figure 3 As shown, the bottom edge of blade 6 is an arc-shaped edge, which facilitates the sliding cutting of the self-adhesive label surface by blade 6 during use.

[0023] Furthermore, such as Figure 1 As shown in Figure 3, the bottom of the pressure rod 12 contacts and presses against one side of the upper surface of the pressure shaft 4. During use, the pressure rod 12, in conjunction with the torsion spring 9, applies elastic pressure to the pressure shaft 4, facilitating the elastic sliding cut of the blade 6.

[0024] Furthermore, such as Figure 3 As shown, the two arms of the U-shaped bracket 10 are integrally connected to the inner ends of the two torsion springs 9. In use, the U-shaped bracket 10, together with the torsion springs 9 and the pressure rod 12, performs elastic compression.

[0025] Furthermore, such as Figure 2 As shown, the slide groove 5 has a "7" shaped structure with the horizontal end being higher at the front and lower at the back. During use, it facilitates the pressure shaft 4 to slide along the vertical end of the slide groove 5 as the blade 6 swings and cuts. After use, the pressure shaft 4 can be locked into the horizontal end of the slide groove 5, so that the blade of the blade 6 is suspended in the air. This prevents the blade of the blade 6 from being squeezed and contacted with the bottom of the inner wall of the housing 1 for a long time when not in use, which would cause damage to the blade and shorten the service life of the blade 6.

[0026] In addition, the blades 6 can be further configured as multiple parallel blades according to the required cutting width, so as to cut the non-adhesive labels to the required smaller width. The working principle of the torsion spring 9 controlling the U-shaped bracket 10 and the pressure bar 12 to perform elastic extrusion is a mature existing technology, so it is not described further here.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
