Description

Technical Field

[0001] This invention relates to the field of rubber band equipment technology, and in particular to an automatic rubber band cutting and splicing device and its usage method. Background Technology

[0002] In modern industrial production, the molding, cutting, and transplanting of rubber bands is a crucial step, widely used in manufacturing, packaging, and other fields. Currently, the market demand for rubber band processing is increasing, and traditional manual methods are no longer sufficient to meet the requirements of large-scale production due to low efficiency, high labor intensity, and inconsistent quality. While some existing automated equipment has improved production efficiency to some extent, its limited functionality prevents the integration of rubber molding, cutting, and transplanting, leading to complex production processes and increased production costs.

[0003] Traditional rubber molding and cutting equipment relies primarily on mechanical cutting, which has low precision and is prone to product damage. Furthermore, due to the low level of automation, it requires significant manual labor, making operation complex and inefficient. The transplanting process also often needs to be done manually, further increasing the labor intensity and time costs of production.

[0004] To address the aforementioned issues, there is an urgent need for an automated device capable of integrating rubber molding, cutting, and transplanting to improve production efficiency, reduce production costs, and ensure the stability and consistency of product quality.

[0015] A method for using an automatic rubber band cutting and splicing device includes the following steps:

[0016] S1. First, the rubber strip is transferred to the bonding plate by the first loosening roller and the second loosening roller. Then, the first micro cylinder is activated, which drives the moving fixed knife to move, thereby fusing the two rubber strips and then cutting them.

[0017] S2. The horizontal plate is moved by the fourth micro cylinder and moved to the corresponding position. Then the second micro cylinder is activated to move the two moving blocks. When the moving blocks move, they will cause the first expansion plate to unfold, thereby expanding the rubber strip. When the rubber strip is large, the two second expansion plates will be driven by the third micro cylinder to expand it a second time, so as to accommodate rubber strips of different sizes.

[0018] S3. After the rubber strip is extended, the second drive source is activated, which drives the horizontal plate to rotate and move the horizontal plate to the corresponding transplanting mechanism.

[0019] S4. A rubber strip is placed on the feeding cylinder. The rubber strip is conveyed by the feeding frame. After the rubber strip moves to the corresponding position, the third drive source drives the shift belt to move. The shift belt drives the clamping block to clamp one end of the rubber strip. Then, the positioning suction plate is activated to adsorb the rubber strip.

[0020] S5. The scissors are driven by the drive module to cut the adhesive strip. Then, the adhesive strip is attracted by the moving limit suction plate and placed on the hot melt plate by the moving frame.

[0021] S6. The moving mechanism places the rubber strip on the hot melt plate, the moving limit suction plate then places the rubber strip on the rubber strip, and then the hot melt plate is activated, thereby bonding the rubber strip and the rubber strip together through the hot melt plate.

[0022] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0023] This invention, through the coordinated operation of a frame, cutting mechanism, moving mechanism, and transplanting mechanism, enables the molding, cutting, and transplanting of rubber. The frame provides the basic structure and stability of the device, ensuring the effective installation and operation of each mechanism. The cutting mechanism utilizes an ultrasonic fixed blade and moving blade module. A first and second loosening roller precisely feed the rubber strips to the bonding plate, and ultrasonic vibration heats and bonds the ends of two rubber strips together. An electric push rod then drives the moving fixed blade to cut the rubber strips, achieving efficient splicing and cutting. The moving mechanism, through the coordinated movement of a horizontal plate, a moving block, and an expansion plate, expands the spliced ​​rubber strips to the required size to accommodate different product specifications. A fourth micro-cylinder moves the horizontal plate to a designated position, ensuring accurate positioning of the rubber strips. The transplanting mechanism, through the cooperation of a feeding cylinder, a moving frame, a fifth micro-cylinder, and a positioning suction plate, transfers the molded rubber strips to subsequent processes, ensuring continuous and automated production. The cooperation of these mechanisms reduces manual intervention and improves production efficiency and product quality. The device is highly automated, enabling efficient rubber molding, cutting, and transplanting operations, which greatly shortens the production cycle, reduces production costs, and is suitable for large-scale production applications.

When the moving blocks 32 move, they will drive the first expansion plate 34 to unfold, thereby expanding the rubber strip. When the rubber strip is large, the two second expansion plates 37 will be driven by the third micro cylinder 36 to expand it a second time, so as to accommodate rubber strips of different sizes.

A shifting belt (415) is sleeved between the mating frame (414) and the third drive source (413). A clamping block (416) is fixedly connected to the shifting belt (415). An eighth micro cylinder (417) is fixedly connected to the bottom of the mounting plate (11). A positioning suction plate (418) is fixedly connected to the output end of the eighth micro cylinder (417). A hot melt plate (419) is fixedly connected to the mounting plate (11), and a clamping plate (420) is movably connected to the hot melt plate (419). A second fixing block (422) is symmetrically fixedly connected to one side of the movable frame (42), and a second vertical shaft (423) slides between the corresponding second fixing blocks (422). The bottom of the second vertical shaft (423) is fixedly connected to the top of the mounting plate (11).

4. A method of using the automatic rubber band cutting and splicing device according to any one of claims 1-3, characterized in that, Includes the following steps: S1. First, the rubber strip is transferred to the bonding plate (24) by the first loosening roller (27) and the second loosening roller (28). Then, the first micro cylinder (212) is started, and the moving fixed knife is moved by the first micro cylinder (212) to fuse the two rubber strips together and then cut them. S2. The horizontal plate (31) is moved by the fourth micro cylinder (38). The horizontal plate (31) will move to the corresponding position. Then the second micro cylinder (33) is activated to move the two moving blocks (32). When the moving blocks (32) move, they will drive the first expansion plate (34) to unfold, thereby expanding the rubber strip. When the rubber strip is large, the two second expansion plates (37) will be driven by the third micro cylinder (36) to expand it a second time. This way, it can adapt to rubber strips of different sizes. S3. After the rubber strip is extended, the second drive source (311) is started, and the horizontal plate (31) is rotated by the second drive source (311) to move the horizontal plate (31) to the corresponding transplanting mechanism (4); S4. A rubber strip is placed on the feeding cylinder (41). The rubber strip is conveyed by the feeding frame (48). After the rubber strip moves to the corresponding position, the third drive source (413) drives the shift belt (415) to move. The shift belt (415) drives the clamping block (416) to clamp one end of the rubber strip. Then, the positioning suction plate (418) is activated to adsorb the rubber strip. S5. The scissors (411) are driven by the drive module (410) to cut the adhesive strip. Then, the adhesive strip is attracted by the moving limit suction plate (47), and then the adhesive strip is placed on the hot melt plate (419) by the moving frame (42). S6. The moving mechanism (3) places the rubber strip on the hot melt plate (419), moves the limiting suction plate (47) to place the rubber strip on the rubber strip, and then starts the hot melt plate (419) to bond the rubber strip and the rubber strip through the hot melt plate (419).
