Description

Technical Field

[0001] The utility model relates to the technical field of resistor film cutting, in particular to a resistor film cutting machine. Background Art

[0002] A resistor film cutter is a device used to cut resistor film into strips with resistor units. Typically, the resistor film is first placed on a fixture, and then the entire fixture is sent into the cutter for pressing and cutting. The fixture is designed with positioning posts to fix the single piece of resistor film and is equipped with a tool to align it to the corresponding position. During operation, the pre-punched holes in the resistor film must first be aligned with the positioning posts, and then a buffer sheet and pressure plate are placed on the film. The entire fixture is then sent into the cutter for cutting. After cutting is completed, the pressure plate and buffer sheet need to be removed separately, as well as the cut resistor film and waste material. This process is relatively complicated and reduces work efficiency. In addition, since the buffer sheet is the only buffer between the tool and the pressure plate, the tool wear is relatively severe.

[0003] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the utility model to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.

[0004] In order to solve the above-mentioned problems, the present invention provides the following technical solutions: A resistor film cutting machine includes a film cutting machine body, which is characterized in that: an extrusion component is provided in the working area of ​​the film cutting machine body, and a connecting component is provided between the extrusion component and the extrusion end of the extrusion component. When the working area of ​​the film cutting machine body is started, it is compressed, and the extrusion end makes the resistor film contact with the blade of the clamp, and the resistor film is cut. During this process, the connecting component is gradually shortened, and the shortened length of the connecting component is greater than the compressed length of the working area of ​​the film cutting machine body.

[0005] On the basis of the above technical solution, the present invention can also be improved as follows.

[0006] As a preferred solution of the resistive film cutting machine described in the present invention, the extrusion assembly includes a support block, a pressure block, a connecting part and a reset part. The connecting part and the reset part are arranged between the support block and the pressure block. The reset part is sleeved on the outer surface of the connecting part. The pressure block is the extrusion end of the extrusion assembly.

[0007] As a preferred solution of the resistive film cutting machine described in the present invention, the connecting component is composed of a cross rod, a round block, and a cylinder, the round block is connected to the support block, the cross rod is connected to the round block, and the cross rod sealing sleeve is arranged in the main cavity of the cylinder.

[0008] As a preferred solution of the resistive film cutting machine of the present invention, the main cavity is connected to the auxiliary cavity through a channel, the main cavity, the channel and the auxiliary cavity are all located inside a cylinder, and the cylinder is connected to the pressing block.

[0009] As a preferred solution of the resistive film cutting machine of the present invention, the extrusion assembly further comprises a pad block, a slot is provided at the bottom of the pad block, the support block is clamped in the slot and fixed by screws provided on the pad block.

[0011] The beneficial effect of the present invention is that in the working area of ​​the film cutting machine body, pressure is gradually applied through the connecting parts.

In actual operation, multiple resistor films can even be stacked on the fixture, which greatly improves work efficiency. At the same time, the use of an extrusion component instead of a buffer sheet is more effective in protecting the tool. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] Example

[0027] Reference Figures 1 to 6 , is an embodiment of the present utility model, which provides a resistance film cutting machine, such as Figure 1 As shown, the film cutter body 100 is provided with a pressing assembly 200 in the working area of ​​the film cutter body 100, and a connecting component 204 is provided between the pressing assembly 200 and the pressing end of the pressing assembly 200. When the film cutter body 100 is started, the working area is compressed, and the pressing end makes the resistive film contact with the blade of the clamp 400, and the resistive film is cut. During this process, the connecting component 204 is gradually shortened, and the shortened length of the connecting component 204 is greater than the compressed length of the working area of ​​the film cutter body 100.

[0028] Specifically, the extrusion assembly 200 is installed at the upper and lower positions of the working area of ​​the film cutting machine body 100. The extrusion assembly 200 is equivalent to the pressure plate and buffer sheet included in the clamp 400, which plays a role in cutting the resistor film and protecting the blade when squeezing furniture. Specifically, while the connecting component 204 is gradually compressed in the working area of ​​the film cutting machine body 100, the deformation of the connecting component 204 itself is gradually shortened. For example, a simple spring is used, which can effectively reduce the pressure acting on the blade. At the same time, the reaction of the spring can also ensure that the resistor touch is cut when it is squeezed. Such a cutting principle is the same as that of the existing clamp 400 with a pressure plate and a buffer sheet, but the worker only needs to install the resistor film on the clamp, eliminating the operation steps of using a pressure plate and a buffer sheet. In reality, multiple resistor films can be installed on the clamp 400 and stacked, which greatly improves work efficiency. At the same time, using the extrusion assembly 200 to replace the buffer sheet is more effective in protecting the tool.

[0029] In order to further illustrate the effect of the connecting component 204 on protecting the tool, the connecting component 204 can be specifically, Figure 5-Figure 6 As shown, the extrusion assembly 200 includes a support block 202, a pressure block 203, a connecting component 204 and a reset component 205. The connecting component 204 and the reset component 205 are arranged between the support block 202 and the pressure block 203. The reset component 205 is sleeved on the outer surface of the connecting component 204. The pressure block 203 is the extrusion end of the extrusion assembly 200. The connecting component 204 is composed of a cross rod 204a, a round block 204a-1, and a cylinder 204b. The round block 204 a-1 is connected to the support block 202, the cross rod 204a is connected to the round block 204a-1, and the cross rod 204a sealing sleeve is arranged in the main cavity 204b-1 of the cylinder 204b. The main cavity 204b-1 is connected to the auxiliary cavity 204b-3 through the channel 204b-2. The main cavity 204b-1, the channel 204b-2, and the auxiliary cavity 204b-3 are all located inside the cylinder 204b. The cylinder 204b is connected to the pressing block 203;

[0030] The extrusion assembly 200 uses a cross rod 204a head sealing sleeve to be arranged in the main cavity 204b-1 of the cylinder 204b to achieve a buffering effect. During compression, the cross rod 204a squeezes the medium in the main cavity 204b-1 into the auxiliary cavity 204b-3 through the channel 204b-2 (in this process, the wine has completed the cutting of the resistor film if the cross rod 204a does not touch the bottom). The channel 204b-2 is narrow and has a strong linearity when the pressure is released to cope with the uneven extrusion of the film cutting machine body 100 during braking, thereby better protecting the tool on the fixture 400. The reset member 205 sleeved on the connecting component 204 is used to restore the cross rod 204a and the cylinder 204b after being squeezed, and also has the effect of buffering and supporting.

[0031] To facilitate installation of the extrusion assembly 200, Figure 2 、 Figure 3 As shown, the extrusion assembly 200 further includes a pad 201, a slot 201a is provided at the bottom of the pad 201, and the support block 202 is clamped in the slot 201a and fixed by screws 201b provided on the pad 201. The assembly is mounted on the film cutting machine body 100 in a sleeve manner to become a part thereof, and can also be disassembled, achieving a flexible use effect;

[0032] In order to quickly cut the resistor film on the fixture 400, Figure 1 、 Figure 4 As shown, a groove 300a is formed on the upper surface of the support assembly 300. The support assembly 300 is arranged at the bottom of the working area of ​​the film cutting machine body 100, and the extrusion assembly 200 is arranged at the top of the working area. The side surface of the clamp 400 contacts the intersection of the groove 300a.

[0033] Placing the clamp 400 at the corner of the groove 300a on the upper surface of the support component 300 is equivalent to positioning the clamp 400. The clamp is locked when the corners of the clamp and the corners of the groove are aligned. In this way, the staff only needs to align them quickly, which is easy to operate and helps to improve film cutting production capacity.
