Description

Technical Field

[0001] This utility model relates to the field of silicone cutting equipment technology, and in particular to a silicone gasket cutter. Background Technology

[0002] Silicone gaskets are functional materials widely used in electronics, industry, and automotive fields, primarily for electrical insulation, shock absorption, and sealing. When processing ring-shaped silicone gaskets, a silicone tube is typically fitted onto the rotating shaft of a cutting machine, and then the tube is slit using a cutter. The specific structure of the cutting machine can be found in patent document CN110696059A. Because the silicone tube has a certain degree of elasticity, it must be tautly fitted onto the rotating shaft to ensure stability during slitting. Since silicone tubes are generally quite thick, fitting and removing the silicone gaskets is very laborious and difficult to do manually, usually requiring a pair of cylinders for assistance. This not only increases the complexity of the equipment but also affects production efficiency. Utility Model Content

[0003] To address the problems mentioned in the background art, the purpose of this utility model is to provide a silicone gasket cutter.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A silicone pad cutter includes a base, a circular cutter, and a cross slide. A column is mounted on the top of the base, and a rotating shaft is horizontally mounted in the middle of the column. The cross slide is mounted on the top of the column and drives the circular cutter to move radially and axially along the rotating shaft. A lifting mechanism is mounted on the base near the column, and a tensioning shaft is rotatably mounted on the lifting end of the lifting mechanism. The tensioning shaft is parallel to and below the rotating shaft. A fan-shaped contact plate is sleeved on the rotating shaft. The contact plate is hollow, and several through holes are evenly distributed on the end face of the contact plate facing away from the column. A connecting nozzle communicating with its own inner cavity is provided on the surface of the contact plate. A linear drive mechanism is horizontally mounted on the column and drives the contact plate to move axially along the rotating shaft.

[0006] Furthermore, a motor that drives the rotating shaft to rotate is installed on the column.

[0007] Furthermore, the lifting mechanism includes a first telescopic cylinder and a mounting base. The first telescopic cylinder is vertically mounted on the base, and the mounting base is fixed on the piston rod of the first telescopic cylinder. The tensioning shaft is rotatably mounted inside the mounting base.

[0008] Furthermore, the linear drive mechanism includes a second telescopic cylinder and a connecting arm. The second telescopic cylinder is horizontally mounted on the column, and the connecting arm is fixed between the piston rod and the contact plate of the second telescopic cylinder.

[0009] Furthermore, the radius ratio of the tensioning shaft to the rotation shaft is 1:10.

[0010] The beneficial effects of this utility model are as follows: the silicone tube is tightened by the joint of the rotating shaft and the tensioning shaft, which is more labor-saving and quicker to install and remove the silicone tube than the method of using a single shaft to tighten and install the silicone tube; the abutment plate can be set to ensure that the silicone tube will not be displaced when rotating, and the abutment plate can also spray lubricant to lubricate the end face of the silicone tube and avoid excessive friction between the silicone tube and the abutment plate when rotating.

[0014] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0015] like Figures 1-2As shown, the silicone pad cutter includes a base 1, a circular cutter 2, and a cross slide 3. A column 4 is mounted on the top left side of the base 1. A rotating shaft 5 is horizontally mounted in the middle of the column 4. A motor 6 that drives the rotating shaft 5 is mounted on the column 4. The cross slide 3 is mounted on the top of the column 4. The cross slide 3 is used to drive the circular cutter 2 to move radially and axially along the rotating shaft 5. A first telescopic cylinder 7 is vertically mounted on the base 1 near the column 4. A mounting base 71 is fixed to the piston rod of the first telescopic cylinder 7. A tensioning shaft 8 is rotatably mounted inside the mounting base 71. The tensioning shaft 8 is arranged parallel to the lower part of the rotating shaft 5. The radius of the tensioning shaft 8 is 1:10 to the radius of the rotating shaft 5. A fan-shaped contact plate 9 is sleeved on the rotating shaft 5. The contact plate 9 is hollow and has several through holes 91 evenly arranged on its right end face. The surface of the contact plate 9 is provided with a connecting nozzle 92 that communicates with its own inner cavity. The connecting nozzle 92 is used to connect a lubricant delivery pipe (not shown in the figure). A second telescopic cylinder 10 is horizontally installed on the column 4 above the rotating shaft 5. A connecting arm 93 is fixed between the piston rod of the second telescopic cylinder 10 and the contact plate 9. The second telescopic cylinder 10 can drive the contact plate 9 to move along the axial direction of the rotating shaft 5.

[0016] In actual use, first bring the tensioning shaft 8 and the rotating shaft 5 close together to facilitate fitting the silicone tube 110 onto both. Then move the tensioning shaft 8 away from the rotating shaft 5 to tension the silicone tube 110. Next, place the contact plate 9 against the left end face of the silicone tube 110 and connect the connecting nozzle 92 to the lubricant delivery pipe. Spray lubricant onto the left end face of the silicone tube 110 through the through hole 91. Turn on the motor 6 and the cross slide 3. The rotating shaft 5 can drive the silicone tube 110 to move. The cross slide 3 drives the circular cutter 2 to approach the rotating shaft 5, thereby cutting the silicone tube 110.

[0017] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
