DETAILED DESCRIPTION

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The invention of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The invention is selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various inventions with various modifications suitable for specific purposes.

[0020] See also Figures 1 to 5 In this embodiment, a raw material auxiliary stirring device for the production and processing of PVA fully degradable film is provided, including a base 1 and a cavity 2, the upper end surface of the base 1 is installed with the cavity 2, and a connecting seat 11 is rotatably installed at the bottom of the cavity 2 through a bearing, and a stirring rod 13 is clamped on the upper end surface of the connecting seat 11 through a first clamp 12, and a connecting frame 14 is installed at the other end of the stirring rod 13, and a fixing seat 15 is installed on the outer wall of the cavity 2, and an adjusting motor 16 is installed on the upper end surface of the fixing seat 15, and the connecting frame 14 is installed at the output end of the adjusting motor 16, and a discharge port is symmetrically installed at the bottom of the cavity 2, and a control valve is installed on the outer wall of the discharge port. When working, the raw materials are put into the cavity 2, and the adjusting motor 16 is started to drive the stirring rod 13 to rotate. The rotation of the stirring rod 13 makes the raw materials mixed evenly, avoids poor molding effect, and does not require manual stirring, thereby improving the stirring efficiency.

[0021] The connecting frame 14 and the stirring rod 13 are screwed together through an adjusting screw 17. When working, the adjusting screw 17 is rotated to remove the stirring rod 13, which is pulled upward to be taken out, so as to facilitate cleaning.

[0022] A feed pipe 18 is inserted into the upper end face of the fixed seat 15, and a guide cavity 19 is installed on the upper end face of the feed pipe 18. A filter screen 21 is installed on the inner wall of the guide cavity 19. The filter screen 21 is arranged obliquely. When working, the raw materials enter the guide cavity 19 and are filtered by the filter screen 21 to prevent large particles of raw materials from entering the cavity 2, thereby affecting the stirring effect.

[0023] The left end face of the guide cavity 19 is provided with an opening, in which a sealing plate 22 is installed by snap-fitting. During operation, the filter screen 21 is arranged tilted so that large particles of raw materials roll to the left side of the filter screen 21. The sealing plate 22 is opened, and the raw materials are discharged through the opening for recycling, thereby preventing them from clogging the filter screen 21 and affecting the filtering effect.

[0024] A profile frame 23 is installed on the left end face of the sealing plate 22, and a slide seat 24 is symmetrically installed on the front and rear end faces of the guide cavity 19. The inner end of the profile frame 23 and the outer end of the slide seat 24 are connected by sliding cooperation. When working, the profile frame 23 is pulled to the left, thereby driving the sealing plate 22 to move, so that the opening is opened, which is convenient for discharging large-particle raw materials.

[0025] The left end face of the guide cavity 19 is provided with a bottom plate, and the upper end face of the bottom plate is provided with a recovery cavity 25. When in operation, the recovery cavity 25 recovers the large particles of raw materials that fall into the cavity, so that the large particles of raw materials can be reused after being ground.

[0026] During specific operation, the raw materials enter the guide cavity 19 and are filtered through the filter screen 21 to prevent large particles from entering the cavity 2, thereby affecting the stirring effect. Then the raw materials enter the cavity 2, and the adjustment motor 16 is started to drive the stirring rod 13 to rotate. The rotation of the stirring rod 13 makes the raw materials mixed evenly to avoid poor molding effect. The stirring process cannot be performed manually, thereby improving the stirring efficiency. The adjusting screw 17 is rotated to remove the adjusting screw 17, and the stirring rod 13 is driven to be pulled upward to be taken out, so as to facilitate its cleaning.
