This invention discloses a high-precision dual-purpose adhesive film production device for both forward and reverse coating, comprising a frame, a linear guide rail mounted on top of the frame, and a roller seat drive assembly on the outer side of the frame. The roller seat drive assembly includes a forward coating roller seat and a reverse coating roller seat slidably connected to the outer side of the linear guide rail. A forward coating heating roller is mounted on the forward coating roller seat, and a forward coating scraper is mounted on top of the forward coating heating roller. A reverse coating heating roller is mounted on the reverse coating roller seat. This invention employs a dual-roller seat independent drive combined with a linear guide rail structure, ensuring smooth and skew-free roller movement, fundamentally avoiding the roller slippage problem that occurs during adjustment in traditional equipment. The dual heating rollers allow for functional interchangeability, enabling quick switching between forward and reverse coating modes. The integrated limit, gap adjustment, and gap elimination structures significantly improve the accuracy of adhesive gap control and operational stability, meeting the requirements of high-precision adhesive film production.

The utility model relates to the technical field of anti-smashing radar, and disclose a barrier trigger anti-smashing radar, including anti-smashing radar body, the bottom of anti-smashing radar body is provided with auxiliary installation mechanism, the back of anti-smashing radar body is provided with body installation mechanism. The barrier trigger anti-smashing radar, utilize the strong magnetic attraction piece that sets up in the inside of fixed frame and sliding frame, can be fitted in the surface of barrier with auxiliary installation mechanism, through sliding slide, can adjust the position of small size positioning drill hole and large size positioning drill hole on the surface of barrier, and then can adjust the punching position, the structural design of hard positioning plate makes it not produce the condition of deformation, simultaneously under any weather, the strong magnetic attraction piece can be adsorbed on the outside of barrier, makes auxiliary installation mechanism can adapt to various weather, will not be affected by the environment, even under the humid state, can install anti-smashing radar body, also will not produce skew, improved the convenience of installation.

The utility model discloses a main shaft mounting structure of an ultra-precision grinding machine, which improves the rigidity and the strength of the whole structure so as to ensure the machining precision of the grinding machine, and comprises a beam assembly, a sliding seat and a ram, the beam assembly comprises a pair of cross beams arranged in the Y-axis direction and a pair of longitudinal beams perpendicular to the cross beams. The end parts of the cross beams and the longitudinal beams are connected with each other and define a rectangular structure; the sliding base is arranged in the rectangular structure, the two sides of the sliding base are in sliding fit with the cross beam, and a Y-axis motor used for driving the sliding base to move in the Y-axis direction is arranged. A movable hole is formed in the central axis of the sliding seat; the ram is in sliding fit in the movable hole, and a mounting hole for mounting a main shaft is formed in the central axis of the ram; a pair of Z-axis motors used for driving the ram to move in the Z-axis direction are arranged on the opposite side walls of the movable hole.

This utility model relates to a tool for measuring the furnace lining of an aluminum electrolytic cell, belonging to the field of electrolytic cell measurement technology. It includes a handheld part with scale lines, a tank insertion part at the end of the handheld part, and a movable scale sleeved on the handheld part and movable along the handheld part in both the lateral and longitudinal directions. When it is necessary to measure the furnace lining thickness at different locations in the aluminum electrolytic cell, it is only necessary to move the handheld part along the longitudinal direction of the movable scale to achieve multi-point measurement of the furnace lining in the aluminum electrolytic cell.
