This utility model discloses a film shaping device, including an operating table and an adjusting base for controlling the lifting and lowering of the film. A stretching box and a cooling box are respectively located on the front and rear sides of the operating table. The stretching box contains a heating roller, a tensioning roller, and a guide roller. Openings are provided on both the left and right sides of the stretching box. A first groove and a second groove are provided on the left and right sides of the operating table of the stretching box. A rotatable screw is located in the first groove, and a moving block is threaded onto the screw. A rotatable screw is vertically located above the first groove, and a moving block is threaded onto the screw. A connecting frame is provided on the moving block. A guide rod is located in the second groove, and a sliding block is provided on the guide rod. A guide rod is vertically located above the sliding block, and a sliding block is provided on the guide rod. A connecting frame is provided on the sliding block. The two ends of the tensioning roller's rotating shaft are rotatably connected to the connecting frame and the connecting frame.

The utility model belongs to the technical field of sound insulation cotton production equipment, and particularly relates to a sound insulation cotton thickness measuring device which comprises a measuring table with the upper surface passing through sound insulation cotton, a measuring opening is formed in the measuring table in a penetrating mode, symmetrical mounting plates are fixed to the two sides of the measuring table, and laser displacement sensors are arranged at the upper end and the lower end of the measuring table respectively. The two laser displacement sensors are symmetrically arranged and vertically correspond to each other through a measuring port, a right-angle plate is fixed to each laser displacement sensor, fixing plates are fixed to the upper end and the lower end of the mounting plate on one side, and adjusting seats capable of being vertically adjusted are mounted on the fixing plates; it can be understood that the double laser displacement sensors which are oppositely arranged up and down are adopted, the thickness of the sound insulation cotton is measured in a non-contact mode, and contact deformation errors are avoided; the height of the sensor is independently adjusted to adapt to different thicknesses, accurate alignment of the sensor and the sensor is ensured through horizontal adjustment, meanwhile, sound insulation cotton with different widths can be adjusted and measured, and the flexibility and precision of measurement are both considered.

The utility model discloses a kind of positioning cutting device of air pipe, it is related to air pipe processing technical field, including support frame, the inside fixed of support frame is with the guide frame of horizontal arrangement, the side of guide frame is provided with support plate, the top of support plate is provided with the adjusting assembly of adjusting cutting position. The utility model has beneficial effect as follows: using the meshing transmission of driving gear and toothed plate, linear motion of support plate is converted from rotary motion, realize the horizontal adjustment of cutting position, transmission mode precision is high, can accurately control the position of cutting blade in horizontal direction, control cutting position error in extremely small range, support block and connecting plate can be driven to move up and down by air cylinder, thereby reach the effect of adjusting cutting height, make cutting depth keep consistent, guarantee the flatness and perpendicularity of air pipe cutting section, improve the quality and precision of air pipe production.

The utility model discloses a horizontal adjustable lifting work platform, including work platform and support board, be provided with adjusting assembly between work platform and support board, adjusting assembly with support board adjusting activity fixed, adjusting assembly can let work platform adjust height or adjust angle, wherein each support arm adjusting assembly includes joint cover, ball head screw rod, limit pin and screw thread cooperation mechanism, joint cover is fixedly connected with work platform, and limit pin transversely penetrates joint cover and ball head screw rod, makes ball head screw rod can with limit pin as the axle relative joint cover rotation to realize to work platform horizontal adjustment, ball head screw rod lower part penetrates support board and is connected with screw thread cooperation mechanism, and screw thread cooperation mechanism is rotatable to be arranged with support board and is axially fixed, makes the rotation screw thread cooperation mechanism can drive ball head screw rod along its axial movement to realize the lifting adjustment of work platform relative to support board.

This invention belongs to the technical field of auxiliary equipment for slurry balance pipe jacking machines, specifically a balancing device for slurry balance pipe jacking machines. The device includes a tunneling machine, an internal cutterhead assembly, a slurry conveyor on the right side of the cutterhead assembly, a pipe on the right side of the tunneling machine, and a bolster on the right side of the pipe. Multiple hydraulic cylinders are mounted on the upper end of the bolster, and a leveling device and a fixing device are installed on the top of the bolster. Through the above structural cooperation, when the bolster tilts, the inclined end of the sleeve shaft drives a bevel gear to move along the driven rod, causing the inclined bevel gear to mesh with a second bevel gear. Power is provided by a motor, causing the threaded rod to connect with the sleeve rod, thereby moving the base up and down to achieve horizontal adjustment of the bolster. This prevents the tunneling machine from shifting due to the bolster's tilt, reduces the eccentric force on the device, and improves its service life.
