Abstract

The utility model relates to a cut-off knife for a household sealing machine. Comprising a cutter holder, a cutter frame is hinged to one side of the cutter holder, and a plurality of protrusions making contact with the surface of the cutter holder are arranged on the lower end face of the cutter frame. A sliding rail is arranged in the middle of the cutter frame, a cutter is arranged in the sliding rail in a sliding mode, the protrusions are distributed on the two sides of the cutter frame, the protrusions on the two sides make contact with the cutter base respectively to clamp a sealing bag in the using process, and then the cutter operates to cut the slice-shaped sealing bag. And the contact surface of the cutter frame and the sealing bag is reduced by adopting the design of the bulge, so that the pressure required for fixing the sealing bag can be reduced. Due to the adoption of the design of the bulges, the contact surface between the cutter frame and the sealing bag can be reduced, and the pressure required for fixing the sealing bag can be reduced. The elastic protrusions are adopted, so that better adaptability and anti-skid performance can be achieved, and the sealing bag can be better fixed.

Description

Technical Field

[0001] The utility model relates to a cutter, in particular to a cutter used for a household sealing machine. Background Art

[0002] The sealing machine puts food into a sealed bag, then vacuums and seals it. After sealing, it cuts the excess edges, or breaks the sealed bag for use. The blade of the sealing machine tends to become blunt after long-term use. Conventional cutters are placed horizontally at the top of the sealing machine. The lower end of the cutter and the knife seat are not tightly fitted, which can easily cause a gap. Especially in the case of plastic deformation, local bending deformation will reduce the clamping effect of the sealed bag. When in use, the sealed bag is prone to slipping, affecting the cutting effect. On the other hand, cutting without aligning the blade will also cause the sealed bag to slip. Utility Model Content

[0003] In order to solve the above-mentioned deficiencies of the existing cutting knife of the sealing machine, the utility model provides a cutting knife for the sealing machine in order to improve the clamping effect and cutting effect of the cutting knife on the sealed bag.

[0004] The technical solution adopted by the utility model is: a cutter, including a cutter seat, a cutter frame hinged on one side of the cutter seat, and a plurality of protrusions in contact with the surface of the cutter seat on the lower end surface of the cutter frame; a slide rail is provided in the middle of the cutter frame, and a cutter is slidably arranged in the slide rail, and the protrusions are distributed on both sides of the cutter frame. When in use, the protrusions on both sides contact the cutter seat to clamp the sealed bag, and then the cutter can be operated to cut the sheet-shaped sealed bag. The use of the protrusion design to reduce the contact surface between the cutter frame and the sealed bag can reduce the pressure required to fix the sealed bag.

[0005] As one of the preferred solutions of the cutter, the cutter includes a push protrusion extending from the upper end of the slide rail, a blade with an inclined cutting edge is embedded at the lower end of the push protrusion, and a guide block is provided at the lower end of the blade.

[0006] As one of the preferred solutions for the cutter, a groove is provided in the middle of the cutter seat, and the lower end of the cutter enters the groove when the cutter slides.

[0007] As one of the preferred solutions of the cutter, the protrusion is elastic. The use of the elastic protrusion can have better adaptability and anti-slip performance.

[0008] The utility model has the beneficial effects that: the use of the convex design reduces the contact surface between the cutting frame and the sealing bag, thereby reducing the pressure required for fixing the sealing bag. The use of the elastic convex can have better adaptability and anti-slip performance to better fix the sealing bag. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The utility model will be further described below in conjunction with the specific drawings.

[0016] like Figures 1 to 4 As shown: a cutter 5 includes a cutter seat 1, a cutter frame 2 is hinged on one side of the cutter seat 1, and the lower end surface of the cutter frame 2 is provided with a plurality of protrusions that contact the surface of the cutter seat 1; a slide rail 4 is provided in the middle of the cutter frame 2, and a cutter 5 is slidably provided in the slide rail 4, and the protrusions are distributed on both sides of the cutter frame 2. When in use, the protrusions on both sides contact the cutter seat 1 to clamp the sealed bag, and then the cutter 5 can cut the sheet-shaped sealed bag. The use of the protrusion design to reduce the contact surface between the cutter frame 2 and the sealed bag can reduce the pressure required to fix the sealed bag. The cutter 5 includes a push protrusion 51 extending from the upper end of the slide rail 4, and a blade 52 with an inclined blade edge is embedded at the lower end of the push protrusion 51, and a guide block 53 is provided at the lower end of the blade 52. A groove 11 is provided in the middle of the cutter seat 1, and the lower end of the cutter 5 enters the groove 11 when sliding.

[0017] As an improvement to the above embodiment, the protrusions may be made of elastic materials such as rubber. The elastic protrusions have better adaptability to height differences and are more anti-slip for the sealing bag.

[0018] As a further improvement of the above embodiment, Figure 5 As shown, the cutting frame 2 is plugged and fixed with the fixing seat 6, and the fixing seat 6 includes two vertical blocks 61. The upper outer edges of the vertical blocks 61 are provided with guide cutting angles, and the lower end surface of the cutting frame 2 is provided with a socket 7 that cooperates with the vertical blocks 61.
