The pressing roller bracket can reciprocate around the bolt journals; the pressing roller is fixed to the pressing roller bracket; each of the two bolts connecting the pressing roller bracket has a torsion spring, one end of which presses on the pressing roller bracket and the other end presses on the pressing roller. Under the torsion of the torsion spring, the pressing roller moves closer to the feeding roller; the pressing roller bracket handle is fastened to the pressing roller bracket; when installing the tofu cloth, turn the pressing roller handle to the left to make the pressing roller move away from the feeding roller, creating a certain distance between the two rollers. The tofu cloth is then lowered from the middle from top to bottom. The pressing roller bracket handle is then released, and the pressing roller presses the tofu cloth onto the feeding roller.

[0008] An optimized structure includes a running mechanism comprising a linear guide rail, a guide rail bearing housing, and a running frame. The linear guide rail is fixedly connected to the top frame. The guide rail bearing housing has a through hole for the linear guide rail and a slide rail that dynamically engages with it. The guide rail bearing housing and the linear guide rail are slidably connected, allowing for reciprocating movement during operation. The lower ends of the running frame are fixed to the guide rail bearing housing. A sensor shield is mounted on the running frame. The fabric pressing roller bracket has bolt through holes, and two bolts with journals pass through the running frame as axles, which are then bolted to the running frame.

[0009] Turn on the motor switch to supply power; the motor runs, driving the rack and pinion to rotate; the rack and pinion mesh with the rack; under the reaction force of the rack, the motor drives the running frame to move along the linear guide rail; while the running frame moves, the cloth feeding motor also rotates, driving the sprocket to mesh with the transmission chain, the transmission chain meshes with and drives the cloth feeding roller sprocket, and the cloth feeding roller sprocket drives the cloth feeding roller; under the action of the torsion spring, the pressure roller presses the tofu cloth tightly onto the cloth feeding roller; the cloth feeding roller rotates counterclockwise to feed the cloth, and under the pressure of the pressure roller, the cloth feeding roller drives the tofu cloth to move downwards, and the tofu cloth is laid on the tray below, achieving flat laying of the tofu cloth.

[0010] When the running motor moves to the left or right stop sensor, the sensor cover plate blocks the left or right stop sensor. When the left or right stop sensor is blocked by a metal object, it triggers a power cut-off, and the running motor stops running, bringing the running frame to a stop at the designated position.

[0011] An optimized structure has a slide rail on one side of the top frame; the running mechanism also includes running frame support pulleys; a linear guide rail is fixedly connected to the other side parallel to the slide rail of the top frame; the two ends of one side of the running frame are fixed to the guide rail bearing box, and the running frame support pulley is installed and connected on the side opposite to the slide rail of the top frame, and the running frame support pulley can reciprocate along the slide rail of the top frame.

[0012] An optimized structure includes a running frame that also includes a running motor bracket and a cloth-laying motor bracket; the running motor bracket and the cloth-laying motor bracket are fixed on the running frame; the running motor is fixed on the running motor bracket, and the cloth-laying motor is fixed on the cloth-laying motor bracket.

[0013] An optimized structure includes a top frame that also includes a left stop sensor bracket and a right stop sensor bracket; the left stop sensor bracket and the right stop sensor bracket are fastened to the top frame; the left stop sensor is fixed to the left stop sensor bracket by locking bolts, and the right stop sensor is fixed to the right stop sensor bracket by locking bolts, with the left stop sensor and the right stop sensor positioned on the outside of the rack; the sensor shield is installed and connected to the running motor connected to the running frame.

[0014] An optimized structure includes a tofu cloth anti-fall drag bar for the cloth feeding mechanism. The tofu cloth anti-fall drag bar is fixed below the outer and inner tofu cloth supports on the running frame. When the tofu cloth is used up and only the tail end remains, the tail end falls onto the drag bar and is driven by the cloth feeding drive roller to continue spreading the cloth downwards. The tofu cloth anti-fall drag bar plays the role of supporting the tail end of the tofu cloth and preventing the tofu cloth from directly hitting the freshly poured tofu pudding.

[0015] An optimized structure includes baffles on the running frame, which are close to the tofu cloth to prevent it from falling and piling up freely during the descent.

[0016] The working principle is as follows: First, place the tofu cloth on the outer and inner tofu cloth supports. Move the handle of the pressing roller support to the left so that the pressing roller is separated from the releasing roller. There is a distance between the pressing roller and the releasing roller. Put one end of the placed tofu cloth down from top to bottom through the gap between the two rollers. The tofu cloth passes from top to bottom between the releasing roller and the pressing roller. Release the handle of the pressing roller support. The pressing roller will press the tofu cloth onto the releasing roller.

[0017] Turn on the motor switch to supply power; the motor rotates, driving the rack and pinion gear to rotate; the rack and pinion gear meshes with the rack teeth, and the motor, under the reaction force of the rack, drives the running frame to move along the linear guide rail; at the same time as the running frame moves, the cloth feeding motor also rotates, driving the drive sprocket to mesh with the transmission chain, which in turn drives the cloth feeding roller sprocket, which in turn drives the cloth feeding roller; the pressure roller, under the action of the torsion spring, presses the tofu cloth tightly onto the cloth feeding roller; the cloth feeding roller rotates counterclockwise to feed the cloth, and under the pressure of the pressure roller, the cloth feeding roller moves downward, laying the tofu cloth on the tray below, thus achieving a flat laying of the tofu cloth.

[0018] When the running frame moves from one end to the other and reaches the designated position, the sensor shield on the running motor will block the left stop sensor and the right stop sensor. When the left stop sensor and the right stop sensor encounter a metal object, they will trigger a power cut-off, the running motor will stop running, and the running frame will stop at the designated position.

[0019] Then, manually pour the tofu pudding. After pouring the tofu pudding, turn on the power switch again to power the motor. The motor will move in the other direction to release the tofu cloth. Repeat the above operation to realize the electric release of the tofu cloth.

[0020] The positive effects of this utility model are: it can be used with various textured tofu cloths, both large and small, and can also be used to place single or double layers of cloth, with precise and neat cloth placement; it reduces the physical exertion of personnel, saves time, and increases production efficiency.
