Description

Technical Field

[0001] The utility model relates to the technical field of cutting machines, in particular to a machine head with up-and-down adjustment of a cutting tool for cutting processing. Background Technique

[0002] At present, in the process of fabric processing, since the fabric often needs to be cut according to production requirements, it is difficult to ensure the cutting quality by manual cutting of workers, and the efficiency is relatively low at the same time. Therefore, a cutting machine for efficiently cutting fabrics has emerged. The cutting machine is a machine suitable for cutting fabrics such as cotton, wool, silk, and leather, and can cut fabrics of different shapes, different angles, and different lengths according to different processing requirements, and has the advantages of high automation degree and stable operation. Since the cutting machine needs to be used in many places, it is necessary to optimize its machine head.

[0003] For example, a cutting machine head device is disclosed in the Chinese utility model patent with the publication number CN206368295U. In the above prior art, although the pressing plate presses the fabric to prevent the cutting tool from lifting the fabric during the rising process, thereby ensuring that the fabric is flat and there are no wrinkles, the cutting tool is installed inside the vibration box. When the machine head is processing, generally, the cutting tool is moved inside the vibration box. However, the vibration box will shorten the service life of the cutting tool due to vibration wear when driving the cutting tool to cut. Moreover, the cutting tool needs to move up and down while being vibrated, and the friction during the movement will further accelerate the wear of the cutting tool, reducing the service life of the cutting tool again. Therefore, it is necessary to design a machine head that can protect the cutting tool and extend its service life. Summary of the Utility Model

[0004] To solve the technical problem that the vibration box driving the cutting tool to move up and down will accelerate the wear of the cutting tool, the utility model provides a machine head with up-and-down adjustment of a cutting tool for cutting processing.

[0005] The utility model is realized by adopting the following technical solutions: A machine head with up-and-down adjustment of a cutting tool for cutting processing, including a machine head body, the machine head body includes a bracket assembly, a vibration box assembly arranged on one side of the bracket assembly for cutting, a cutter head assembly arranged at the bottom of the vibration box assembly for rotating the cutting tool, and a knife grinding assembly arranged on one side of the cutter head assembly for grinding the cutting tool. A limiting assembly for limiting and protecting the vibration box assembly is arranged on one side of the bracket assembly, and driving assemblies for driving the vibration box assembly to move up and down are arranged on both sides of the limiting assembly. The limiting assembly includes a limiting base installed on one side of the bracket assembly and two limiting plates fixedly installed on one side of the limiting base.

[0006] Through the above technical solution, the driving component enables the oscillating box component to move up and down on the limiting component, thus avoiding the situation where the oscillating box component always moves the cutting tool up and down, thereby extending the service life of the cutting tool.

[0007] As a further improvement of the above solution, mounting grooves are formed on the opposite surfaces of the two limiting plates.

[0008] Through the above technical solution, the oscillating box component is allowed to move along the direction of the mounting groove, thereby restricting the oscillating box.

[0009] As a further improvement of the above solution, protective plates are provided on one side of each of the two limiting plates.

[0010] Through the above technical solution, the protective plate can protect the cylinder inside the mounting groove.

[0011] As a further improvement of the above solution, two heat dissipation fans for heat dissipation are installed on the limiting base.

[0012] Through the above technical solution, the heat dissipation fans dissipate heat from the oscillating box component.

[0013] As a further improvement of the above solution, the driving component includes an oscillating box cylinder arranged inside the mounting groove and a plurality of fixing blocks fixedly sleeved on the oscillating box cylinder, and the plurality of fixing blocks are fixedly installed on the inner wall of the mounting groove, and the pushing end of the oscillating box cylinder is fixedly installed with the oscillating box component.

[0014] Through the above technical solution, the oscillating box cylinder can drive the oscillating box component to move up and down, thus avoiding the need for the cutting tool to be driven up and down by the oscillating box.

[0015] As a further improvement of the above solution, a tool disc cylinder for driving the tool disc component to move up and down and close is provided on one side of one of the limiting plates.

[0016] Through the above technical solution, when the tool disc cylinder is started, the tool disc component will move up and down and close or open, thereby enabling the cutting tool to rotate.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] By providing a limiting component and a driving component, when the cutting tool needs to extend out of the machine head body, the driving component cooperates with the limiting component to make the oscillating box component move downward. Thus, the oscillating box component extends the cutting tool out of the machine head body. When the cutting tool needs to retract into the machine head body, the driving component can also move the oscillating box component upward. Such a setting can not only achieve the up and down adjustment of the cutting tool, but also avoid the situation where the up and down adjustment of the cutting tool can only use the oscillating box, preventing the up and down adjustment of the cutting tool by the oscillating box from causing the cutting tool to wear faster.

[0024] Next, in combination with the drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0025] Please refer to Figures 1-3 , a head for cutting and processing with up-and-down adjustment of the tool in this embodiment includes a head body 1. The head body 1 includes a bracket assembly 2, an oscillation box assembly 3 for cutting disposed on one side of the bracket assembly 2, a cutter head assembly 4 disposed at the bottom of the oscillation box assembly 3 for rotating the tool, and a knife sharpening assembly 5 disposed on one side of the cutter head assembly 4 for grinding the tool. A limiting assembly for limiting and protecting the oscillation box assembly 3 is disposed on one side of the bracket assembly 2. Driving assemblies for driving the oscillation box assembly 3 to move up and down are disposed on both sides of the limiting assembly. The limiting assembly includes a limiting base 601 installed on one side of the bracket assembly 2 and two limiting plates 602 fixedly installed on one side of the limiting base 601. Installation grooves are formed on the opposite surfaces of the two limiting plates 602. Protection plates 8 are disposed on one side of the two limiting plates 602. Two cooling fans 9 for heat dissipation are installed on the limiting base 601. The driving assembly enables the oscillation box assembly to move up and down on the limiting assembly, so as to avoid always using the oscillation box assembly 3 to move the tool up and down, thereby prolonging the service life of the tool. The protection plate 8 can protect the cylinder inside the installation groove.

[0026] Refer to Figure 2 and Figure 3, the driving assembly includes a vibration box cylinder 701 arranged inside the installation groove and a plurality of fixing blocks 702 fixedly sleeved on the vibration box cylinder 701. The plurality of fixing blocks 702 are fixedly installed on the inner wall of the installation groove. The pushing end of the vibration box cylinder 701 is fixedly installed with the vibration box assembly 3. The vibration box cylinder 701 can drive the vibration box assembly 3 to move up and down, thus avoiding the need for the tool to be driven up and down by the vibration box.

[0027] Combined with Figures 1-3 , on one side of one of the limiting plates 602, there is a cutter head cylinder 10 for driving the cutter head assembly 4 to move up and down and close.

[0028] The implementation principle of a cutting head with tool up-and-down adjustment in the embodiment of the present application is as follows: When the tool needs to move up and down, the vibration box cylinder 701 will be started, and the pushing end will move up and down, so that the entire vibration box assembly 3 moves up and down. In this way, the vibration box will drive the tool inside to move up and down. Only need to adjust the tool position in advance. In this way, there is no need to use the vibration box to drive the tool up and down. The limiting plate 602 and the protection plate 8 will also protect the vibration box assembly 3. Such a setting can not only realize the up-and-down adjustment of the tool, but also avoid that the up-and-down adjustment of the tool can only use the vibration box, preventing the up-and-down adjustment of the tool by the vibration box from causing the tool wear rate to increase.

[0029] The above implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the protection scope required by the present invention.
