[0029] Specifically, in this embodiment, the surfaces of the active roller 5 and the driven roller 6 have a rubber layer to enhance the friction force on the surface of the bag.

[0030] The worker controls the active roller 5 to rotate in the clockwise direction, and the corresponding driven roller 6 rotates counterclockwise by rotating the connecting assembly in the reverse direction, so that the material bag in the extrusion gap 7 can be transferred from the side of the extrusion assembly close to the barrel 2 to the side of the extrusion assembly away from the barrel 2.

[0031] In a preferred embodiment of the present utility model, the reverse rotation coupling assembly includes a driving gear 8 and a driven gear 9 meshing with the driving gear 8, and an auxiliary frame 10 for mounting the driving gear 8 and the driven gear 9 is provided on the frame 1, the driving gear 8 is connected to one side of the driving roller 5, the driven gear 9 is connected to one side of the driven roller 6, and a handle 11 for driving the driving roller 5 to rotate is provided on the other side of the driving roller 5.

[0032] Specifically, in this embodiment, during the extrusion process, when the worker turns the handle 11, it is advisable to observe the movement of the bag. If the upper surface of the bag is not moving smoothly, tightening the upper part of the bag from the side of the extrusion assembly away from the barrel 2 can make the bag move more smoothly.

[0033] The driving gear 8 is axially fixed to one side of the driving roller 5 , and the driven gear 9 is axially fixed to one side of the driven roller 6 .

[0044] Specifically, in this embodiment, the lower pump body of the sprayer is inserted into the feed port, and the sealing ring 22 abuts against the outer wall of the lower pump body to achieve sealing.

[0045] In a preferred embodiment of the present invention, a support frame 23 for supporting the discharge pipe 19 is further provided on the frame 1 .

[0046] Specifically, in this embodiment, the support frame 23 is arranged across from below the discharge pipe 19 and supports the discharge pipe 19. Since the discharge pipe 19 has a certain length and needs to be plugged into the lower pump body of the sprayer, the reliability of the discharge pipe 19 can be effectively improved by providing the support frame 23.

[0047] In summary, before preparing materials, workers control the two sliding covers 13 to move to both sides to expose the feed port of the barrel 2, which is simple and convenient to operate; an end cover 20 is provided at the discharge pipe 19, and workers can remove the end cover 20 to insert the lower pump body of the sprayer into the feed port, and the sealing ring 22 is against the outer wall of the lower pump body to achieve sealing.

[0048] When preparing materials, workers place the material bag filled with paint on the storage platform, then insert one end into the squeezing gap 7 and open the other end so that the opening is located above the material barrel 2, and then control the handle 11 to rotate, and the active roller 5 and the driven roller 6 rotate in opposite directions to roll the material bag to the side away from the material barrel 2, so that the materials can be prepared quickly, and during the pouring process, the workers do not need to hold the material bag, which is more labor-saving and improves the material preparation efficiency. The residual paint in the material bag is poured out more cleanly under the squeezing action of the active roller 5 and the driven roller 6.
