6results about How to "Simplify cleaning" patented technology

This application discloses a Rockwell hardness testing system, belonging to the technical field of measurement. The Rockwell hardness testing system includes a support plate, a Rockwell hardness tester, and a wiping mechanism. The Rockwell hardness tester includes a body and an indenter and a sample stage mounted on the body. The indenter and sample stage are arranged opposite each other along the height direction, and the body is mounted on the support plate. The wiping mechanism includes a wiping component and a driving component. The driving component is mounted on the support plate, and its output end is connected to the wiping component, driving the wiping component to wipe the indenter and sample stage. With this design, after placing the sample in front of the sample stage, the driving component drives the wiping component to move, causing the wiping component to automatically wipe the indenter and sample stage, simplifying the cleaning work before hardness testing, improving cleaning efficiency, and thus improving the efficiency of sample hardness testing.

The application provides an industrial waste gas waste heat recovery heat exchange mechanism and a working method thereof, relates to the technical field of environmental protection production equipment, and improves the internal structure of the original heat exchanger, replaces the original single-tube heat exchange pipe structure with a self-breathing heat exchange pipe, and cooperates with a pump machine capable of performing power conversion in real time, utilizes the continuous extrusion and stretching effect of the self-breathing membrane part of the self-breathing heat exchange pipe under the wave type progressive spray liquid hydraulic action, greatly reduces the possibility of a large amount of scale accumulation on the inner wall of the self-breathing heat exchange pipe in a long time heat conversion process, guarantees the heat conversion efficiency in a long time working process, and is particularly suitable for spray liquid and other heat fluid heat conversion operations with complex components and extremely easy scale accumulation in the heat conversion process. The heat exchanger assembly mechanism used in cooperation with the self-breathing heat exchange pipe can achieve good waste heat recovery effect on industrial waste gas.

This utility model provides a waste chip recovery device for NdFeB polishing, relating to the field of NdFeB processing technology. The device includes a processing table, a polishing box connected to the top of the processing table, and a vacuum cleaner fixedly connected to the top of the processing table. The output end of the vacuum cleaner is connected to a chip suction pipe, the left end of which extends into the inner cavity of the polishing box. An anti-clogging component is provided on the right side of the polishing box, including a mounting box, the inner cavity of which houses a motor. This technical solution, by setting up the anti-clogging component, achieves efficient and centralized collection of waste chips generated during NdFeB polishing, effectively avoiding pipe blockage during collection and significantly improving waste chip collection efficiency. The anti-clogging component utilizes vibration to prevent waste chips from accumulating in the transmission pipe, ensuring smooth operation during chip suction.

The utility model discloses a non-stick cooking container which comprises a container body, the container body is provided with a containing groove used for containing food materials, random lines are arranged in the containing groove, the random lines comprise a plurality of concave pits distributed randomly and a plurality of convex points formed by the concave pits in an enclosing mode, and the convex points are arranged in the containing groove. The area of the random lines is not smaller than one half of the area of the inner side of the containing groove. According to the utility model, more air gaps are created and direct physical contact points are reduced through the introduction of random lines, and mutual support among rice particles is increased through the irregularity of the lines, so that rice can be separated from one another more easily in the heating expansion process instead of being tightly attached to the surface of a container. According to the cooking utensil, the contact area of rice and the inner surface of the cooking utensil can be reduced by about 50%, so that the falling convenience of rice is greatly improved while the excellent cooking effect is kept, good non-stickiness is achieved, and the dual requirements of a user for cooking efficiency and eating convenience are met.

The utility model discloses a water cooling device for efficiently cooling an LED of a letterpress printing machine, which relates to the technical field of LED cooling of printing machines and comprises a shell, a circuit board fixedly connected to the lower side of the shell, lamp beads fixedly connected to the lower surface of the circuit board, and a cooling component mounted in the shell and comprising a cooling fin I fixedly mounted in the shell, a main cooling pipeline is arranged in the shell in a penetrating mode, a connecting shell is detachably connected to the shell, second cooling fins are fixedly connected to the interior of the connecting shell, the second cooling fins abut against the first cooling fins, an expansion cooling pipeline is arranged in the second cooling fins in a penetrating mode, and a cooling fan is fixedly connected to the top of the connecting shell; the outer wall of the cooling fan is covered with a dust cover, a filter plate is slidably connected to the position, close to the lower side of the cooling fan, in the connecting shell, and air outlets are distributed in the side wall, located below the filter plate, of the connecting shell. According to the utility model, a double heat dissipation guarantee mechanism with water cooling as a main part and air cooling as an auxiliary part is formed, and heat generated by the lamp beads can be quickly and continuously led out.

The utility model belongs to the field of full-automatic screen printing machines, particularly relates to a printing mechanism for a full-automatic screen printing machine, and aims to solve the problems that an existing printing mechanism for the screen printing machine is inconvenient to adjust, poor in adaptability and difficult to maintain, different clamping devices need to be replaced for templates of different sizes, and operation is tedious in the aspects of replacement and cleaning of a scraper. According to the technical scheme, the device comprises a rack, the inner wall of the rack is fixedly connected with two first vertical plates which are symmetrically arranged, a same connecting rod is fixedly connected between the two first vertical plates, a same sliding rod is fixedly connected between the two first vertical plates, and the outer wall of the sliding rod is slidably sleeved with a movable seat. By arranging the clamping assembly with the adjustable position, the device can adapt to templates of different sizes, the clamping device does not need to be replaced, the cost is reduced, the production efficiency is improved, and the scraper is fixedly connected to the mounting plate through simple screws and is convenient to disassemble and replace.
