Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, and in particular to an upper die device for a hot press cutting machine. Background Technology

[0002] Leather is a natural material, usually obtained by tanning animal skin. When processing leather, it is necessary to maintain the flatness of the material and the precision of processing. Rolling the leather on the outer wall of the roller helps to store and transport it properly, and also prevents the leather from being damaged or wrinkled during processing. After the leather is rolled on the outer wall of the roller, it can be more convenient to send it into the hot press cutting machine for processing. By using hot press molds in the hot press cutting machine, the rolled leather can be precisely cut, shaped or embossed to make various leather products, such as leather clothing, shoes, bags, etc.

[0003] In the process of hot pressing and cutting leather, the hot pressing and cutting device is located on a conveyor. The conveyor has winding structures at both ends to transport the leather and wind up any excess material. During the process of placing the leather onto the die, the leather is cut into a specific shape by a longitudinally moving hot pressing die. The outer wall of the conveyor belt must be kept clean; however, it is difficult to maintain the cleanliness of the conveyor belt in real time during production. Manual wiping is tedious, time-consuming, and physically demanding. An unclean conveyor belt can lead to dust or stains contaminating the leather surface, causing resistance and friction, thus affecting the quality and appearance of the cutting result. Therefore, those skilled in the art have provided a die-mounting device for a hot pressing and cutting machine to solve the problems mentioned in the background art. Utility Model Content

[0010] The feeding structure includes roller frames fixed on both sides of the conveyor, mounting rollers rotatably installed inside the roller frames for winding the cotton yarn, and a motor fixed at one end of the roller frames with its output end connected to the mounting rollers.

[0011] Furthermore, the outer wall of the protrusion is rotatably mounted with balls arranged in a circular array, and the balls roll and fit against the inner wall of the guide frame.

[0012] Specifically, when the bump presses against the guide frame, it adheres to the inner wall of the guide frame through the ball bearings, thereby reducing the friction and resistance of the contact surface.

[0013] Furthermore, guide rods are provided at both ends of the travel frame, and a sliding sleeve bracket is provided below the conveyor. The guide rods are slidably installed inside the sliding sleeve bracket, and the motor is fixed inside the sliding sleeve bracket.

[0014] Specifically, the travel frame slides inside the sliding sleeve bracket via the guide rod, thus providing sliding guidance for the travel frame during forward and backward movement.

[0015] Furthermore, the upper end of the travel plate is provided with equally spaced rubber particles;

[0016] Specifically, the rubber particles increase the friction between the travel plate and the cotton yarn, thereby improving the fit between them.

[0017] Furthermore, a symmetrically distributed rotating seat is provided on one side of the roller frame, and a tensioning roller assembly is rotatably installed inside the rotating seat, and the cotton yarn is slidably installed on the outer wall of the tensioning roller assembly;

[0018] Specifically, the rotating seat provides rotational support for the tension roller assembly, which in turn provides sliding support for the cotton yarn conveyor belt passing through the tension roller assembly.

[0019] Furthermore, a sliding sleeve bracket 2 is provided on one side of the rotating seat, and a guide rod 2 is slidably installed inside the sliding sleeve bracket 2 at one end of the rotating seat. A spring with both ends connected to the sliding sleeve bracket 2 and the outer wall of the rotating seat is sleeved on the outside of the guide rod 2.

[0020] Specifically, the rotating seat slides inside the sliding sleeve bracket two via the guide rod two, providing sliding support for the rotating seat. During sliding, an elastic force is applied by the spring, allowing the moved rotating seat to be reset by the pull of the spring's elastic force.

[0021] 2. Beneficial effects

[0022] Compared with existing technologies, the advantages of this utility model are:

[0023] In this invention, the wound leather moves at the top of the conveyor, and the hot pressing mold is driven by the cutting hydraulic rod to cut the leather by hot pressing, so that the leather is formed into a specific shape. During use, a cotton yarn belt is set at the bottom of the conveyor to rub against the outer wall of the conveyor belt. The cotton yarn belt cleans the dust or stains on the outer wall of the conveyor belt, thereby ensuring the cleanliness of the conveyor belt. The upper mold device of the hot pressing cutter is automatically cleaned, reducing labor costs and avoiding the influence of unclean outer wall of the upper mold device on the quality and appearance of the leather during belt hot pressing cut.

[0024] Meanwhile, the cleaning cotton yarn belt can be automatically replaced, making the cleaning process of the conveyor belt structure used in the upper die of the hot press cutting machine more convenient.

[0025] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
