Description

Technical Field

[0001] The utility model provides a waste paper beater for pulp molding production, belonging to the technical field of paper product processing. Background Art

[0002] In the paper processing industry, to protect the environment and reduce plant harvesting, various processes have emerged to recycle waste paper, such as books, newspapers, and corrugated boxes, into new paper products. Pulp molding is a three-dimensional papermaking technology within the paper processing industry. It uses waste paper as raw material, shaping paper products into specific shapes using specialized molds on a molding machine. It offers four key advantages: The raw material is waste paper, including cardboard, waste carton paper, and waste white-edged paper, which is widely available; the production process, consisting of pulping, adsorption molding, drying, and shaping, is environmentally friendly; it is recyclable; and its volume is smaller than that of foamed plastic, allowing for overlap and convenient transportation. In addition to making lunch boxes and tableware, pulp molding is also increasingly used for industrial cushioning packaging and is experiencing rapid growth. A waste paper pulping machine is essential for pulp molding production.

[0003] Existing waste paper pulping machines can basically meet the needs of pulp molding production, but they still have certain defects: because the pulp added to the pulping machine is relatively viscous, the flow rate of the viscous pulp at the pulp inlet and outlet of the pulping machine is relatively slow when adding the pulping machine and discharging the pulped pulp. This can easily lead to blockage of the pulp inlet and outlet of the pulping machine, affecting the normal pulp inlet and outlet. Based on this, the utility model provides a waste paper pulping machine for pulp molding production. Utility Model Content

[0004] The technical problem solved by the utility model is that the flow rate of viscous paper pulp when entering and exiting is relatively slow, which can easily lead to blockage of the pulp inlet and outlet of the pulping machine, affecting the normal pulp inlet and outlet effect.

[0005] In order to solve the technical problem, the technical solution provided by the utility model is: a waste paper beater for pulp molding production, comprising a beating tank, a feed hopper is provided on the top of the beating tank, a discharge port is provided at the bottom of the beating tank, an anti-blocking stirring assembly is provided in the beating tank, an L-shaped frame is provided on the top of the beating tank, a driving assembly for driving the anti-blocking stirring assembly is provided on the top of the L-shaped frame, the anti-blocking stirring assembly comprises a stirring rod, an anti-blocking rod 1 is provided on the top of the stirring rod, which passes through the discharge port and is rotatably connected to the top of the L-shaped frame, a spiral blade 1 is provided on the anti-blocking rod 1, an anti-blocking rod 2 is provided at the bottom of the stirring rod, which is inserted into the discharge port, and a spiral blade 2 is provided on the anti-blocking rod 2.

[0006] Furthermore, the drive assembly includes a drive box fixedly mounted on the inner top wall of the L-shaped frame, a motor is provided on the inner side wall of the drive box, the output end of the motor is fixedly connected to a main gear, and the rod body of the anti-blocking rod is provided with a slave gear placed in the drive box and meshing with the main gear.

[0007] Furthermore, the anti-blocking rod 1 is rotatably connected to the bottom wall of the driving box, and the top end of the anti-blocking rod 1 is rotatably connected to the top of the L-shaped frame through a bearing.

[0008] Furthermore, a plurality of stirring blades placed in a beating tank are equidistantly provided on the circumference of the stirring rod, the spiral blade 1 is placed in the feed hopper, the spiral blade 2 is placed in the discharge port, and the rotation directions of the spiral blade 1 and the spiral blade 2 are opposite.

[0009] Furthermore, a switch valve is provided on the discharge port, and a water inlet is provided on the top of the pulping tank and is placed on one side of the feed hopper.

[0010] Furthermore, an observation window is provided on the side wall of the beating tank.

[0011] Beneficial effects of the utility model:

[0012] The anti-blocking stirring component is driven by the driving component to rotate the anti-blocking rod one and the anti-blocking rod two. The rotation of the anti-blocking rod one drives the spiral blade one to rotate, so that the pulp slurry falls along the rotation of the spiral blade one, which can speed up the feeding flow rate of the viscous pulp slurry and effectively prevent the viscous pulp slurry from clogging the feed hopper. The rotation of the anti-blocking rod two drives the spiral blade two to reverse, and then the viscous pulp falls along the rotation of the spiral blade two after the beating is completed, which can speed up the discharge flow rate of the viscous pulp slurry and effectively prevent the viscous pulp slurry from clogging the discharge port, so as not to affect the normal in and out pulp effect.

[0022] Principle of the utility model

[0023] During use, water is added to the beating tank 1 through the water inlet 18, and pulp slurry is added to the beating tank 1 from the feed hopper 2. Through the drive component 6, the motor 13 is started to rotate forward to rotate the anti-blocking rod 8, and then the stirring rod 7 and the anti-blocking rod 2 10 are rotated. The rotation of the anti-blocking rod 8 drives the spiral blade 1 9 to rotate, so that the pulp slurry falls along the rotation of the spiral blade 1 9, which can speed up the feed flow rate of the viscous pulp slurry and effectively prevent the viscous pulp slurry from clogging the feed hopper 2. The rotation of the stirring rod 7 drives the stirring blade 17 to rotate, and the pulp slurry is mixed with water for beating. The rotation of the anti-blocking rod 2 10 causes the spiral blade 2 11 to rotate. Since the rotation directions of the spiral blade 1 9 and the spiral blade 2 11 are opposite, the rotation of the spiral blade 2 11 causes the pulp slurry at the bottom to be transported upward, effectively improving the beating uniformity of the pulp slurry.

[0024] After the beating is completed, the switch valve is opened, and the pulp that has been beaten is discharged from the discharge port 3. The motor 13 is started to reverse to rotate the anti-blocking rod 1 8, and then the stirring rod 7 and the anti-blocking rod 2 10 are rotated. The rotation of the anti-blocking rod 2 10 drives the spiral blade 2 11 to reverse, and then the viscous pulp after the beating is completed rotates and falls along the spiral blade 2 11, which can speed up the discharge flow rate of the viscous pulp slurry and effectively prevent the viscous pulp slurry from clogging the discharge port.
