Description

Tool fixing structure of trimming machine

technical field

The utility model relates to a tool fixing structure of an edge cutting machine.

Background technique

The edge trimmer is a machine used to cut the edge of the fabric (cotton, wool, rayon, non-woven fabric, etc.), the principle is very simple, just fix the fabric, and then move the knife according to the fabric direction to cut. Through the design of the trimming machine, the finished size of each fabric can be kept similar to reduce human error.

Since the principle of the edge trimmer is very simple, it is only completed by a device that drives the fabric to move, and cooperates with the cutting mechanism of the knife. Therefore, each user can design the size of the machine, the speed of the knife, and the product material according to his own needs. Basically, the edge trimmer can drive the fabric to move by the rollers, and at the same time, cut the fabric with a knife.

However, the above-mentioned existing devices still have shortcomings and need to be improved. Because this existing device uses rollers to drive the fabric to move, and then cuts it with a cutter, but the fabric is usually a soft and malleable object, so it is necessary to make the cutter as close as possible to the rollers, so as not to pull the fabric during cutting. However, in order to fix the tool and avoid interfering with the movement of the roller, it usually maintains a proper gap with the roller. As such, the remaining gap becomes a source of error. And this error will also produce irregular changes according to the material and thickness of the fabric, so that the error of the work done by the edge trimmer is very large, and subsequent processing must be carried out, resulting in loss of manpower and time.

With the improvement of industrial technology, some people may reduce the size of the gap by increasing the precision of rollers and knives, but no matter how advanced the technology is, the basic error still exists, and the error is magnified several times due to the elasticity of the fabric. Furthermore, improving the precision of rollers and knives also means increasing the cost of the machine, and the knives themselves are consumables, so the overall calculation is not economical, and there is still room for improvement.

Contents of the invention

The purpose of the utility model is to provide a tool fixing structure of an edge trimmer, which has a simple structure and powerful functions, greatly reduces the installation cost, and maintains the precision of the work.

Another object of the present utility model is to provide a tool fixing structure of an edge trimmer, which is stable in operation, not easy to be damaged, and the replacement of the tool is quite easy, so that the processing process is smoother.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the tool fixing structure of the trimming machine includes a roller, which is driven to rotate by a transmission mechanism, and a positioning upper pressure wheel is arranged above the roller, and the positioning upper pressure wheel The wheel is driven to rotate by the transmission mechanism, and the positioning upper pressure wheel can be close to the roller to clamp the work piece placed between the roller and the positioning upper pressure wheel. A cutter is arranged beside the roller, and when the roller drives the workpiece to move, the cutter simultaneously cuts the workpiece. The aforesaid rollers are internally provided with an accommodating groove, and a fixed seat is arranged in the accommodating groove, and the lower edge of the fixed seat extends outward to the machine table of the trimming machine, and the cutter includes a fixed blade and a movable blade, and the fixed blade It is arranged on the fixed seat and can be closely attached to the edge of the roller, while the movable blade is tangent to the fixed blade, and driven by the transmission mechanism to swing the movable blade to produce the function of cutting the workpiece.

Compared with the prior art, the utility model has the following advantages: a tool fixing structure of an edge cutting machine, which has simple structure, powerful function, stable operation, not easy to be damaged, can greatly reduce the setting cost, and can maintain the precision of work , the replacement of the tool is quite easy, making the machining process smoother.

Detailed ways

The content of the present utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Example:

Referring to Fig. 1 to Fig. 6, it is a tool fixing structure of a trimming machine proposed by the utility model, the trimming machine 1 includes a roller 2, and the roller 2 is driven to rotate by a transmission mechanism 21. 2. There is a positioning upper pressure wheel 3 above. The positioning upper pressure wheel 3 is driven to rotate by the transmission mechanism. The positioning upper pressure wheel 3 is driven by the swing arm 4. After the user applies force, the positioning upper pressure wheel 3 can Close to the roller 2, so that the work piece 5 (fabric) placed between the roller 2 and the positioning upper pressure roller 3 can be clamped, and driven by the rotation of the roller 2 and the positioning upper pressure roller 3. Be provided with cutter 6 beside this roller 2, and this cutter 6 outward appearance is the scissors structure, when this roller 2, positioning upper pressing wheel 3 drive work piece 5 to move, this cutter 6 cuts this work piece 5 simultaneously.

In order to ensure the cutting precision of the work piece 5, it is better to make the cutter 6 closely adhere to the edge of the roller 2. In this way, only the cutting edge of the work piece 5 needs to be aligned with the edge of the roller 2 to perform precise cutting. Cutting work. For this reason, the utility model is provided with accommodating groove 22 inside this roller 2, and this accommodating groove 22 is provided with fixed seat 7, and the lower edge of this fixed seat 7 extends outwards on the machine platform of this trimming machine 1, Make this fixing base 7 conceal in the roller 2, but do not hinder the rotation of the roller 2. Then, the claimed cutter 6 of the utility model includes a fixed blade 61 and a movable blade 62, and the fixed blade 61 is arranged on the fixed seat 7, so that the fixed blade 61 can be closely attached to the roller 2 edge, and The movable blade 62 is tangent to the fixed blade 61 , and the transmission mechanism 63 drives the movable blade 62 to swing to produce the function of cutting the workpiece 5 .

Therefore, when the roller 2 and the positioning upper pressing wheel 3 rotate, the workpiece 5 can be driven to move, and the blade 6 can be cut synchronously, so that the precise cutting of the workpiece 5 can be completed.

The aforementioned fixed blade 61 is made of a softer material, while the movable blade 62 is made of hard steel, so that the movable blade 62 can be cut for a long time without replacement, and the fixed blade 61 is locked on the On the fixed seat 7, it is convenient to replace when worn out. In addition, the transmission mechanisms 21 and 63 of the roller 2 and the movable blade 62 are driven by a motor in cooperation with a mechanical structure, which is a common structure and will not be repeated here.

The above detailed description is a specific description of the feasible embodiment of the utility model. This embodiment is not used to limit the patent scope of the utility model. Any equivalent implementation or change that does not deviate from the utility model shall be included in this case within the scope of the patent.
