And the processing quality of the veneer is further improved.

The application discloses an automatic coating machine, which comprises a rack, an extrusion roller arranged on the rack, two gas smoothing mechanisms symmetrically arranged on the rack, and gas flow ports arranged on the gas smoothing mechanisms; the gas smoothing mechanisms respectively have first smoothing strokes and second smoothing strokes in the strokes of the gas smoothing mechanisms; in the first smoothing strokes, the two gas smoothing mechanisms move away from each other, and the gas flow ports suck air towards the middle positions of the films on the extrusion roller; in the second smoothing strokes, the two gas smoothing mechanisms move towards each other, and the gas flow ports blow air towards the outer sides of the films on the extrusion roller; in the application, the smoothing piece continuously smoothes the film in the reciprocating process of the gas smoothing mechanism, the film is continuously smoothed in the movement process, the influence of film wrinkles on product forming effect in the film and coating co-extrusion process is avoided, and the device is more flat when the film is smoothed and the coating is contacted.

The invention relates to a laser thickness measuring system for chip thinning and a thickness measuring method, which are applied to the field of chip thinning, the laser thickness measuring system comprises a supporting seat and a mounting seat, the supporting seat is provided with a plurality of adjusting frames, the plurality of adjusting frames are respectively connected with adjusting plates in a sliding manner, and a pressurizing clamp is connected with the plurality of adjusting plates through a connecting unit. An adjusting unit used for driving the adjusting plate to ascend and descend is arranged on the adjusting frame, the grinding machine is arranged on the mounting base, and a grinding disc of the grinding machine corresponds to the pressurizing clamp. The device has the technical effects that the adjusting unit is started, the adjusting plate is driven to ascend and descend along the adjusting frame, the adjusting frame drives the pressurizing clamp to adjust the angle through the connecting unit, the flatness of the pressurizing clamp is adjusted, flexibility is high, a to-be-thinned chip on the pressurizing clamp makes contact with a grinding disc of a grinding machine more smoothly, and the grinding efficiency is improved. And the chip grinding quality and the production efficiency are improved.

The utility model discloses a printing device for carpet processing, which relates to the technical field of carpet processing and comprises a processing table, and a lifting plate component is arranged on the upper surface of the processing table. Two belt wheel mounting seats are symmetrically arranged on the two sides of the lifting plate component, and a mounting frame is arranged at the top of the lifting plate component; a plurality of belt wheels are uniformly arranged on the upper surfaces of the two belt wheel mounting seats at intervals, and a belt wheel motor is arranged at one end of the lower surface of each belt wheel mounting seat; a hydraulic printing component is arranged on the lower surface of the top of the mounting frame; a synchronous belt is arranged on the outer sides of the multiple belt wheels. A plurality of pulley seats are uniformly arranged on the outer side of the synchronous belt at intervals; clamping parts are arranged at the ends, away from the synchronous belt, of the multiple pulley bases. By means of the structure, the two sides of a carpet can be clamped, the situation that the carpet shrinks due to changes of temperature and humidity conditions, and printing deviation is caused is avoided, the height of the bottom plate can be adjusted according to carpets with different thicknesses, a hydraulic printing component can make better contact with the carpet conveniently, and the printing effect is guaranteed.

The invention relates to the technical field of printing equipment, and provides a full-automatic drum-type screen printing machine which comprises a fixed rack, a printing rack, a conveying assembly, a position adjusting assembly, a printing drum, a first motor, an ink scraping assembly, a sliding frame, a mounting frame and a printing assembly, the printing rack is fixedly mounted on the upper portion of the fixed rack, and the conveying assembly is mounted on the printing rack; the position adjusting assembly is mounted on the printing rack, the printing cylinder is fixedly mounted in the printing rack, the first motor is fixedly mounted on the printing rack, the output end of the first motor is fixedly connected with the printing cylinder, the ink scraping assembly is mounted on the position adjusting assembly, the sliding frame is slidably mounted on the printing rack, and the mounting frame is rotatably mounted on the sliding frame. According to the technical scheme, the problem that in the prior art, due to the fact that problems occur when the position of a doctor blade is adjusted, the doctor blade jumps easily in the working process, and the printing quality is affected is solved.

The present invention discloses a dishwasher liner and a dishwasher, wherein the dishwasher liner comprises an annular frame and a back plate, the annular frame comprises at least two plates connected in sequence, the connection between two adjacent plates forms a connecting portion, one end of the annular frame is provided with a flange, the connecting portion has a folding section located at the flange, the back plate is connected to the flange, the back plate is provided with an air avoidance groove corresponding to the folding section, and a sealant is provided between the air avoidance groove and the folding section. The technical solution of the present invention can reduce the risk of water leakage in the dishwasher liner.

The utility model discloses a cold header feed straightening device which comprises a working table, a straightening table is fixedly installed on the top of the working table, the bottom of the straightening table penetrates through and extends to the bottom of the working table, and driving motors which are arranged at equal intervals are fixedly installed on the inner wall of the straightening table.
