Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, specifically a slitting machine for producing EVA foam with a spacing adjustment structure. Background Technology

[0002] Plastic processing, also known as plastic molding processing, is a general term for various processes that transform synthetic resins or plastics into plastic products. Among them, EVA foam materials have a wide range of applications. An EVA slitting machine is an auxiliary device used in the EVA production and processing process to cut semi-finished products into sheets so that they can be better processed in subsequent steps.

[0003] However, existing slitting machines cannot cut multiple objects simultaneously in one direction, resulting in low work efficiency and a longer overall cutting time.

[0004] To address the aforementioned deficiencies, Chinese Patent Publication No. CN213499434U discloses a slitting machine for producing EVA colored foam. The machine includes a support platform with a hollow rectangular frame. A motor is located on the side of the hollow rectangular frame away from the opening. The motor's main shaft passes through one side of the hollow rectangular frame and is connected to a first flange. A cutting device is located on the side of the first flange away from the motor. The cutting device includes a second flange, a rotating shaft, a contact hollow rod, a locking element, and a cutting blade. The second flange is bolted to the first flange. The rotating shaft is fixedly connected to the side of the second flange away from the first flange. An external thread that mates with the locking element is provided on the outer wall of the rotating shaft away from the contact hollow rod and the cutting blade. A shock-absorbing device is provided at the bottom of the hollow rectangular frame. This provides a slitting machine for producing EVA colored foam with a smooth cutting surface, low cost, and multiple cutting openings.

[0005] The aforementioned device utilizes multiple feeding settings to improve cutting efficiency during use. However, the device only cuts for a single size and cannot cut according to different foam sizes, resulting in low processing efficiency. Utility Model Content

[0006] The purpose of this invention is to provide a slitting machine for EVA foam production with a spacing adjustment structure, so as to solve the problem mentioned in the background art that it is not possible to cut according to different foam sizes.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a slitting machine for producing EVA foam with a spacing adjustment structure, comprising a support, a controller fixedly installed at the top of the support, a base fixedly installed on the bottom surface of the support, a cutting blade fixedly installed on the inner side of the base, a protective block fixedly installed on the outer surface of the support, and a support plate fixedly installed on the outer surface of the protective block; a spacing adjustment positioning mechanism is provided on the inner side of the base, the positioning mechanism including a limiting rod fixedly and movably installed on the inner side of the base.

[0008] Furthermore, a servo motor is fixedly installed at the top of the support plate, and an output shaft is rotatably installed at the output end of the servo motor.

[0009] Furthermore, a conductive assembly is fixedly installed on the outer surface of the output shaft, and the output shaft is movably installed on the inner side of the protective block.

[0010] Furthermore, a stepper motor is fixedly installed at the top of the base, a drive shaft is rotatably installed at the output end of the stepper motor, a transmission belt is rotatably installed on the outer surface of the drive shaft, and the drive shaft and the transmission belt form a rotating structure.

[0011] Furthermore, the conveyor belt movably abuts against the inner side of the base, and a buffer spring is fixedly installed on the side of the base near the conveyor belt.

[0012] Furthermore, a positioning block is fixedly installed on the outer surface of the buffer spring, and a limit rod is fixedly installed on the outer surface of the positioning block.

[0013] Furthermore, the positioning block is movably abutted against the outer surface of the conveyor belt, and a guide roller is movably installed on the inner side of the positioning block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) The bracket is supported by the base, and the EVA foam to be processed is manually transported through the conveyor belt. The EVA foam is cut and separated by the cutting knife. The spacing of the processed EVA foam is adjusted under the conduction of the conveyor roller, so as to process EVA foam of different sizes, improve processing efficiency and reduce production costs.

[0016] (2) By starting the servo motor, the servo motor drives the output shaft to drive the transmission component to rotate. The transmission component includes a drive roller for transmitting EVA foam and a pad to reduce equipment wear, thereby extending the service life of the equipment.

[0017] (3) Use protective blocks to increase the protection of the output shaft. By starting the stepper motor, the stepper motor drives the drive shaft to drive the transmission belt to rotate. The transmission belt transports the EVA foam to be processed, thereby improving the processing efficiency.

[0018] (4) While the conveyor belt is transmitting EVA foam, it positions and transmits the EVA foam through the transmission roller. The extension and retraction of the buffer spring facilitates the transmission of EVA foam to different gears. The positioning block is limited by the limiting rod to prevent the positioning block from falling off, thus achieving efficient cutting of EVA foam. Attached Figure Description
