Description

Technical Field

[0001] This utility model relates to the technical field of rubber sealing strip production equipment, and in particular to a cutting device for cutting rubber sealing strips. Background Technology

[0002] After the adhesive backing process, the rubber sealing strip needs to be cut to the required length. The adhesive backing is an adhesive layer applied to one side of the rubber sealing strip to facilitate installation. A protective layer is provided on the outside of the adhesive layer; during installation, the protective layer is peeled off to adhere the rubber sealing strip to the corresponding location.

[0003] In the existing technology, the cutter used to cut rubber sealing strips is a single blade. After cutting, the end face of the rubber sealing strip and the end face of the protective layer are on the same plane. This makes it difficult for the operator to peel the protective layer off the rubber sealing strip during installation, which reduces the efficiency of the installation operation. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a rubber sealing strip cutting device to solve the technical problem that when existing cutting devices cut rubber sealing strips, the end face of the rubber sealing strip and the end face of the protective layer are on the same plane, making it difficult for the operator to peel the protective layer off the rubber sealing strip during installation, which reduces the efficiency of the installation operation.

[0005] The rubber sealing strip cutting device of this utility model includes a bracket, a cylinder mounted on the bracket with its piston rod pointing vertically downward, a blade holder connected to the cylinder, a first cutting blade and a second cutting blade mounted on the blade holder and parallel to each other, and a cutting pad located below the first cutting blade and the second cutting blade, wherein the cutting edge of the first cutting blade is lower than the cutting edge of the second cutting blade.

[0006] Furthermore, a left groove is provided on the left side of the blade holder, the first cutter is disposed in the left groove, and a left pressure block for fixing the first cutter is provided in the left groove. The left pressure block is connected to the blade holder by screws.

[0007] Furthermore, a right groove is provided on the right side of the blade holder, and the second cutter is disposed in the right groove. A right pressure block for fixing the second cutter is provided in the right groove, and the right pressure block is connected to the blade holder by screws. The second cutter is provided with a horizontal edge parallel to the top surface of the right pressure block, and a shim for adjusting the position of the cutting edge of the second cutter is provided between the horizontal edge and the top surface of the right pressure block.

[0008] Furthermore, the rubber sealing strip cutting device also includes a positioning seat for fixing the cutting pad. The positioning seat is provided with a transverse through hole for the rubber sealing strip to pass through. The cutting pad is placed in the transverse through hole. The side wall of the positioning seat is provided with screws for fixing the cutting pad. The positioning seat is also provided with a blade groove that cooperates with the first cutter and the second cutter respectively.

[0009] Furthermore, the distance between the first cutter and the second cutter is 5-10mm.

[0010] The beneficial effects of this utility model are:

[0011] This utility model relates to a rubber sealing strip cutting device, which uses two cutters to cut the rubber sealing strip. The cutting edge of the first cutter is lower than that of the second cutter. The first cutter cuts the rubber sealing strip and the adhesive protective layer attached to it together, while the second cutter cuts only the rubber sealing strip and the adhesive layer attached to it, leaving the protective layer behind during the second cut. After this cutting, a section of the protective layer hangs outside the end face of the rubber sealing strip. During installation, the operator can easily peel off the entire protective layer by pinching the exposed section, thereby improving the installation efficiency of the rubber sealing strip.

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] As shown in the figure, the rubber sealing strip cutting device in this embodiment includes a bracket 1, a cylinder 2 mounted on the bracket with its piston rod pointing vertically downward, a blade holder 3 connected to the cylinder, a first cutter 4 and a second cutter 5 mounted on the blade holder and parallel to each other, and a cutting pad 6 located below the first cutter and the second cutter. The cutting edge of the first cutter is lower than the cutting edge of the second cutter.

[0018] In this embodiment, a left groove 7 is provided on the left side of the blade holder, the first cutter is disposed in the left groove, and a left pressure block 8 for fixing the first cutter is provided in the left groove. The left pressure block is connected to the blade holder by screws.

[0019] The right side of the blade holder is provided with a right groove 9, and the second cutter is disposed in the right groove. The right groove is provided with a right pressure block 10 for fixing the second cutter. The right pressure block is connected to the blade holder by screws. The second cutter is provided with a horizontal edge 11 parallel to the top surface of the right pressure block. A shim 12 for adjusting the position of the cutting edge of the second cutter is provided between the horizontal edge and the top surface of the right pressure block.

[0020] In this embodiment, a blade holder with left and right grooves is used to cooperate with the left and right pressure blocks respectively, which can conveniently and reliably install and fix the first cutter and the second cutter; and by setting a shim between the horizontal edge of the second cutter and the top surface of the right pressure block, the cutting edge position of the second cutter can be easily adjusted.

[0021] In this embodiment, the rubber sealing strip cutting device further includes a positioning seat 13 for fixing the cutting pad 6. The positioning seat has a transverse through hole 14 for the rubber sealing strip to pass through, and the cutting pad is disposed in the transverse through hole. Screws 15 for fixing the cutting pad are provided on the side wall of the positioning seat. The positioning seat also has blade grooves 16 that respectively cooperate with the first cutter and the second cutter. Loosening the screws 15 can adjust the position of the cutting pad 6, thus extending the service life of the cutting pad.

[0022] In this embodiment, the rubber sealing strip cutting device uses two cutters to cut the rubber sealing strip. The cutting edge of the first cutter is lower than that of the second cutter. The first cutter cuts off the rubber sealing strip and the adhesive protective layer attached to it together, while the second cutter only cuts off the rubber sealing strip and the adhesive layer attached to it, leaving the protective layer. After this cutting, a section of the protective layer hangs outside the end face of the rubber sealing strip. In this embodiment, the distance between the first and second cutters is 5-10mm, and the specific distance can be designed according to needs, such as 5mm, 7mm, 10mm, etc. After cutting, the length of the adhesive protective layer exceeds the rubber sealing strip by 5-10mm. During installation, the operator can easily tear off the entire protective layer by pinching this section of adhesive protective layer, thereby improving the installation efficiency of the rubber sealing strip.
