Description

Technical Field

[0001] The utility model relates to the technical field of adsorption devices, in particular to an adsorption device for a single-layer carrier bed. Background Art

[0002] As people's living standards continue to improve, they have higher and higher requirements for materials such as clothing and leather. At present, single-layer cutting tables are required when processing these materials. With the improvement of productivity, there is a greater demand for single-layer cutting tables. The adsorption unit of the existing single-layer cutting table is mainly composed of an adsorption platform, a solenoid valve, an adsorption pipe, and a vacuum pump. A large number of tiny suction holes are opened on the upper surface of the adsorption platform. The tiny suction holes are connected to the inner cavity inside the adsorption platform. When a large number of tiny air holes absorb air, they can adsorb the material and ensure the cutting accuracy of the equipment. However, the inner cavity of the existing ordinary adsorption platform is a single cavity structure, so that the farther the suction hole is from the center of the inner cavity, the smaller the suction force. The adsorption effect on some materials to be cut is not good, which reduces the cutting accuracy of the cutting table. In order to solve the problem of poor adsorption effect, the power of the vacuum pump is usually increased, which has the disadvantages of high cost and high energy consumption. Utility Model Content

[0003] The technical problem to be solved by the present invention is to provide an adsorption device for a single-layer carrier bed, which can make the suction force of each suction hole more balanced, thereby improving the adsorption effect of the material to be treated, that is, improving the cutting accuracy of the carrier bed on the material.

[0004] The utility model provides an adsorption device for a single-layer bed, comprising a vacuum pump and an adsorption platform; a plurality of partitions are fixed inside the adsorption platform and are spaced apart from each other from left to right, the outer edge of each partition is circumferentially fixed and sealed to the inner wall of the adsorption platform, and the plurality of partitions divide the inner cavity of the adsorption platform into a plurality of negative pressure cavities, and a plurality of suction holes are distributed on the upper end surface of the adsorption platform, and the lower end of each suction hole is connected to the negative pressure cavity at the corresponding position; the adsorption device also includes a suction main pipe and a suction branch pipe vertically corresponding to each negative pressure cavity; the bottom of each negative pressure cavity is connected to the corresponding suction branch pipe, all the suction branch pipes are connected to the suction main pipe, and the suction main pipe is connected to the negative pressure suction pipe of the vacuum pump.

[0005] The utility model divides the inner cavity of the adsorption platform into multiple negative pressure cavities, and the lower end of each suction hole is connected to the negative pressure cavity at the corresponding position, so that the distance between each suction hole and the center of the negative pressure cavity can be made smaller, that is, while ensuring that the power of the vacuum pump remains unchanged, the suction force of each suction hole can be made more balanced, thereby improving the adsorption effect of the material to be treated, and also improving the cutting accuracy of the carrier bed on the material.

[0006] In one possible embodiment, the outer edge of each partition is circumferentially welded and sealed to the inner wall of the adsorption platform; by adopting this structure, each partition can be reliably fixed inside the adsorption platform, and the outer edge of each partition can reliably achieve circumferential sealing with the inner wall of the adsorption platform, that is, it can ensure that there is no mutual leakage between adjacent negative pressure chambers.

[0007] In one possible embodiment, each negative pressure cavity is a rectangular structure extending from front to back; each suction branch pipe is connected and fixed with two pipe joints distributed in the front-to-back direction, the pipe joint on each suction branch pipe is fixed to the adsorption platform at the bottom of the corresponding negative pressure cavity, and each pipe joint is connected to the negative pressure cavity at the corresponding position; by adopting this structure, since each negative pressure cavity is a rectangular structure extending from front to back, and since the two pipe joints located on each suction branch pipe are distributed in the front-to-back direction, the negative pressure in the negative pressure cavity can be more balanced, that is, the suction force of the suction hole located above each negative pressure cavity can be more balanced.

[0008] In one possible embodiment, connecting pipes are connected to both ends of the main suction pipe near the ends, and the main suction pipe is connected to the negative pressure suction pipe through the connecting pipes. After adopting this structure, since the two connecting pipes are arranged at both ends of the main suction pipe near the ends, the negative pressure in the main suction pipe can be more balanced, that is, the negative pressure in each suction branch pipe can be more balanced, and thus the suction force of the suction hole located above each negative pressure cavity can be more balanced.
