Abstract
Description
Technical Field
[0001] This application relates to the field of rubber strip cutting technology, and in particular to a rubber strip cutting tool. Background Technology
[0002] Rubber strips are widely used in various industries, such as automobile manufacturing, door and window manufacturing, and electronic equipment manufacturing. Rubber strips include sealing strips and decorative strips. During installation, the ends of the rubber strips can easily interfere with the products on which they are to be installed; therefore, it is necessary to partially cut the ends of the rubber strips.
[0003] Reference Figure 1 An adhesive strip includes a first adhesive portion 1 and a second adhesive portion 2 connected to the first adhesive portion 1. Partial cutting is required at the ends of both the first adhesive portion 1 and the second adhesive portion 2. The portion of the first adhesive portion 1 to be cut is defined as a first cutting portion 11, and the portion of the second adhesive portion 2 to be cut is defined as a second cutting portion 12.
[0004] In the prior art, the first cutting part 11 and the second cutting part 12 are usually cut manually. First, a knife is used to cut a certain length of the sidewalls of the first cutting part 11 and the second cutting part 12. Then, the first cutting part 11 and the second cutting part 12 are cut along a specified length of area perpendicular to the length of the adhesive strip, so that the first cutting part 11 is separated from the first adhesive part 1 and the second cutting part 12 is separated from the second adhesive part 2.
[0005] Regarding the above technical solution, the inventor believes that manually cutting the adhesive strip is too cumbersome. Utility Model Content
[0006] To facilitate localized cutting of adhesive strips, this application provides an adhesive strip cutting fixture.
[0007] The adhesive strip cutting fixture provided in this application adopts the following technical solution:
[0008] A rubber strip cutting fixture includes a cutting base, a first cutting mechanism for cutting a first rubber portion, and a second cutting mechanism for cutting a second rubber portion. The cutting base has a cutting through hole for arranging the rubber strip, and a fixed cutter is provided at the cutting through hole for cutting the sidewalls of the first and second rubber portions. The first cutting mechanism includes a first slider that is inclined and slidably arranged on the cutting base, a first cutting blade mounted on the first slider and arranged toward the cutting through hole, and a first driving member for driving the first slider to slide. The second cutting mechanism includes a second slider that is slidably mounted on the cutting base, a second cutting blade mounted on the second slider and arranged toward the cutting through hole, and a second driving member for driving the second slider to slide.
[0009] By employing the above technical solution, one end of the adhesive strip is inserted into the cutting through-hole of the cutting base. During insertion, a fixed cutter located at the cutting through-hole cuts the sidewalls of the first and second cutting portions of the adhesive strip. A first driving member drives a first slider to slide, causing the first cutter to cut the first cutting portion, thereby detaching the first cutting portion from the first adhesive portion. Similarly, a second driving member drives a second slider to slide, causing the second cutter to cut the second cutting portion, thereby detaching the second cutting portion from the first adhesive portion. Compared to manually cutting the first and second cutting portions, this application facilitates partial cutting of the adhesive strip.
[0010] Optionally, the cutting base is provided with a first groove for the first slider and a second groove for the second slider to slide.
[0011] By adopting the above technical solution, the first slide groove and the second slide groove are configured so that the first slider and the second slider can slide along a fixed path, making the first cutting blade and the second cutting blade more stable when cutting the rubber strip.
[0012] Optionally, the cutting base includes a first fixed seat and a second fixed seat. The first fixed seat has a first half-groove and a second half-groove, and the second fixed seat has a third half-groove and a fourth half-groove. When the first fixed seat and the second fixed seat are in contact, the first half-groove and the third half-groove form the first sliding groove, and the second half-groove and the fourth half-groove form the second sliding groove.
[0013] By adopting the above technical solution, the specific structure of the cutting base is disclosed. The arrangement of the first fixed seat and the second fixed seat makes it more convenient to install the first slider into the first slide groove and the second slider into the second slide groove.
[0014] Optionally, the first fixing seat has a first stepped surface on the side facing the second fixing seat, and the second fixing seat has a second stepped surface for cooperating with the first stepped surface.
[0015] By adopting the above technical solution, the arrangement of the first stepped surface and the second stepped surface ensures that the lengths of the first cutting part and the second cutting part are staggered to meet the cutting requirements when cutting the first cutting part and the second cutting part.
[0016] Optionally, the first fixing seat is provided on the first stepped surface with a first cutting groove that connects the first half groove and the cutting through hole and is used for the sliding arrangement of the first cutting blade, and a second cutting groove that connects the second half groove and the cutting through hole and is used for the sliding arrangement of the second cutting blade.
[0017] By adopting the above technical solution, the first cutting groove is provided so that the first cutting blade can slide within the first cutting groove, thereby reducing the probability of interference with the first / second stepped surface during the sliding process; the second cutting groove is provided so that the second cutting blade can slide within the second cutting groove, thereby reducing the probability of interference with the first / second stepped surface during the sliding process.
[0018] Optionally, the first fixed seat has a first plunger through hole penetrating the front and rear surfaces in the first half-groove, and a first ball spring plunger is installed in the first plunger through hole. The first slider is provided with a first snap-fit groove for abutting and cooperating with the plunger ball of the first ball spring plunger. The second fixed seat has a second plunger through hole penetrating the front and rear surfaces in the second half-groove, and a second ball spring plunger is installed in the second plunger through hole. The second slider is provided with a second snap-fit groove for abutting and cooperating with the plunger ball of the second ball spring plunger.
[0019] By adopting the above technical solution, the injection molding of the first ball head spring and the cooperation of the first locking groove enable the first slider to be fixed at a designated position in the first slide groove so that when the rubber strip is inserted into the cutting through hole, the first cutting blade will not interfere with the rubber strip, thereby facilitating the first cutting blade to cut the first cutting part; the injection molding of the second ball head spring and the cooperation of the second locking groove enable the second slider to be fixed at a designated position in the second slide groove so that when the rubber strip is inserted into the cutting through hole, the second cutting blade will not interfere with the rubber strip, thereby facilitating the second cutting blade to cut the second cutting part.
[0020] Optionally, the first driving component includes a first driving block detachably mounted on the first slider and a first handle mounted on the top of the first driving block; the second driving component includes a second driving block detachably mounted on the second slider and a second handle mounted on the second driving block.
[0021] By adopting the above technical solution, the specific structures of the first driving component and the second driving component are disclosed. Operators only need to pull / press the first handle and the second handle to cause the first slider and the second slider to slide up and down, thereby cutting the first cutting section and the second cutting section.
[0022] Optionally, the first slider has a first T-shaped groove at one end facing the outlet of the first groove and along the width direction, and the bottom of the first drive block has a first T-shaped slide bar for engaging with the first T-shaped groove; the second slider has a second T-shaped groove at one end facing the outlet of the second groove and along the width direction, and the bottom of the second drive block has a second T-shaped slide bar for engaging with the second T-shaped groove.

The connection between the first driving block and the first slider, and the connection between the second driving block and the second slider, can be completed simply by inserting the first T-shaped slider into the first T-shaped groove and the second T-shaped slider into the second T-shaped groove.
[0024] Optionally, a limiting plate may also be installed in the cutting base at the end away from the fixed cutter inlet.
[0025] By adopting the above technical solution, the setting of the limiting plate can limit the length of the rubber strip inserted into the cutting through hole.
[0026] In summary, this application includes at least one of the following beneficial technical effects:
[0027] 1.
