Description

Technical Field

[0001] The utility model relates to the technical field of leather processing, in particular to a fixture for leather cutting with adjustable thickness. Background Technique

[0002] Leather refers to the raw materials obtained from mammals, which are made into items with softness, toughness, ductility and wear resistance through a series of processing and manufacturing processes. It is the animal skin that has been denatured and is not easily perishable after physical and chemical processing such as hair removal and tanning. The leather industry covers the main industries such as leather making, shoemaking, leather clothing, leather goods, fur and its products, as well as the supporting industries such as leather chemicals, leather hardware, leather machinery, and accessories.

[0003] However, in the current prior art, in the process of leather processing, in order to facilitate the matching of leather to products, the leather will be cut into corresponding shapes. During the leather cutting process, the leather will be cut horizontally to adjust the thickness of the leather. However, during the cutting process, the previous fixtures can only clamp and press the leather for fixation, but cannot position the cutting thickness, resulting in the cutter being prone to tilt during the cutting process, resulting in uneven thickness of the cut leather. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fixture for leather cutting with adjustable thickness to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

An auxiliary component for positioning the cutting thickness of the leather is arranged inside the bottom plate. The auxiliary component includes two positioning grooves arranged on the top of the bottom plate. Driving blocks are arranged inside both of the two positioning grooves. A cavity and a hole groove are arranged inside the driving block. A motor is arranged outside the driving block. A gear is arranged at the output end of the motor. A support rod is arranged inside the hole groove. A rack is arranged on one side of the support rod. An adjusting plate is arranged at the top of the support rod. A through groove is arranged inside the adjusting plate. A tool rest and two sliding grooves are arranged inside the through groove. Springs are arranged inside both of the two sliding grooves. A slider is arranged outside the tool rest.

[0007] As a preferred scheme of the utility model, the outside of the pressing plate is connected to the air cylinder of the fixture, and the bottom plate is connected to the cutting table. During cutting, the leather can be placed on the surface of the bottom plate, and the pressing plate can approach the bottom plate through the air cylinder to clamp and fix the leather.

[0008] As a preferred embodiment of the present utility model, the driving block is located within the positioning groove and is slidably connected to the inner wall of the positioning groove through a slide rail. The motor is externally connected to the driving block through bolts, and the output end of the motor is connected to a gear through a coupling. The gear is located within the cavity.

[0009] As a preferred embodiment of the present utility model, the support rod is located within the hole groove and is slidably connected to the inner wall of the hole groove through a slide rail. The rack is externally connected to the side of the support rod close to the cavity through bolts, and the rack is in contact engagement with the gear.

[0010] As a preferred embodiment of the present utility model, the top end of the support rod can extend out of the driving block and is connected to the adjusting plate through bolts. Both of the two chute are communicated with the through groove, and the cutting knife extends into the through groove from the through groove and then contacts the leather during cutting.

[0011] As a preferred embodiment of the present utility model, the tool holder is slidably connected to the inner wall of the through groove through a slide rail. One end of the slider is externally connected to the tool holder through bolts, and the other end extends into the chute. Both ends of the spring are connected to the inner wall of the chute and the slider through welding. The inside of the tool holder is of an inclined structure. The cutting knife can be embedded in the tool holder and the tool holder is pushed out of the through groove by the pressure during cutting.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows: In response to the problems raised in the background art, the present application adopts an auxiliary component. By installing an adjusting plate inside the bottom plate and controlling the height position of the adjusting plate through a gear structure, the adjusting plate can be lifted or lowered according to the thickness to be cut. When the cutting knife cuts, it can extend into the adjusting plate and be clamped with the tool holder. At the same time, the front end of the cutting knife extends out of the tool holder, and the internal tool holder and the adjusting plate are driven to slide out by the driving force of cutting, and the adjusting plate is driven to slide parallel in the bottom plate during the cutting process, ensuring a stable angle during the cutting process.

[0013] The present utility model realizes the guidance of the cutting thickness of the leather, assists in positioning the cutting thickness, and prevents the cutting knife from deflecting in angle by restricting the moving angle of the cutting knife during the cutting process, improving the stability of cutting and ensuring the cutting effect.
