Description

Technical Field

[0001] This utility model relates to the field of pulp molding, and in particular to a pulp mixing and proportioning device for pulp molding. Background Technology

[0002] In the pulp molding process, the paperboard raw material is first crushed by a crushing device to form a pulp. The pulp is then transported to a pulp mixing and proportioning device for mixing and proportioning, thereby ensuring the stability of the pulp concentration to facilitate subsequent molding.

[0003] Most existing slurry mixing and proportioning devices have a wall scraping component inside the device to scrape off the material on the inner wall of the tank or container to ensure thorough mixing. However, in actual use, the wall scraping component usually runs together with the stirring structure, but the slurry will not have a lot of residue sticking to the wall in a short period of time, resulting in unnecessary operation and also generating a lot of friction noise, making it inconvenient to use. Utility Model Content

[0004] The purpose of this utility model is to solve the following problems existing in the prior art: In the actual use of existing slurry mixing and proportioning devices, the wall scraping component usually runs together with the stirring structure, but the slurry will not have a lot of wall adhesion in a short period of time, resulting in unnecessary operation and easy to generate a lot of friction noise, which is inconvenient to use.

[0005] To address the problems existing in the prior art, this utility model provides a pulp mixing and proportioning device for pulp molding processing, including a pulp mixing tank and a conveying pipe. A motor is provided above the pulp mixing tank, and a stirring rod and a stirring paddle are provided at the output end of the motor. The motor is connected to the pulp mixing tank through an electric lifting seat. A gear is provided at the bottom of the stirring rod. A movable disc is provided at the inner bottom of the pulp mixing tank through a movable seat. A connecting ring is provided at the center of the movable disc, and a scraper is also provided on the movable disc.

[0006] Furthermore, the connecting ring has a hollow interior, and its inner wall is provided with several toothed blocks.

[0007] Furthermore, the specifications of the tooth blocks match the rack around the gear, but the spacing between the tooth blocks is greater than the spacing between the racks.

[0008] Furthermore, a plug is provided at the center below the gear, and a socket matching the plug is provided at the center of the connecting ring.

[0009] Furthermore, the scraper frame consists of a support rod and a silicone scraper, the silicone scraper being in contact with the inner wall of the mixing tank.

[0010] Furthermore, the mixing tank is equipped with a concentration detection sensor assembly, and the water pump assembly of the delivery pipe is electrically connected to the concentration detection sensor assembly.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] During daily mixing, the scraper frame is stationary. The electric lifting seat is activated at regular intervals to lower the stirring rod. The lowering of the stirring rod causes the gear to descend into the connecting ring. At this time, the gear meshes with the toothed blocks on the inner wall of the connecting ring. When the stirring rod and gear rotate, the toothed blocks drive the connecting ring and the movable disc to rotate, thereby causing the scraper frame to rotate and scrape the inner wall of the mixing tank. Because the spacing between the toothed blocks is greater than the spacing of the outer rack of the gear, the rotation speed of the connecting ring and the movable disc is lower than the rotation speed of the stirring rod, thus enabling the scraper frame to achieve a slow scraping effect. This solves the problems of unnecessary operation and excessive noise caused by long-term scraping in existing devices, increasing the practicality of this device. Attached Figure Description

[0017] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation details without creative effort are all within the protection scope of this invention.

[0018] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0019] Example 1

[0020] like Figure 1-3As shown, a pulp mixing and proportioning device for pulp molding includes a pulp mixing tank 1 and a conveying pipe 4. A motor 3 is provided above the pulp mixing tank 1. A stirring rod 5 and a stirring paddle 6 are provided at the output end of the motor 3. The motor 3 is connected to the pulp mixing tank 1 through an electric lifting seat 2. A gear 7 is provided at the bottom of the stirring rod 5. A movable disc 8 is provided at the inner bottom of the pulp mixing tank 1 through a movable seat 12. A connecting ring 9 is provided at the center of the movable disc 8. A scraper 10 is also provided on the movable disc 8.

[0021] In this embodiment, the connecting ring 9 has a hollow interior. Several toothed blocks 11 are provided on the inner wall of the connecting ring 9. The specifications of the toothed blocks 11 match the rack around the gear 7, but the spacing between the toothed blocks 11 is greater than the spacing between the racks. An insert is provided at the center below the gear 7, and a socket matching the insert is provided at the center of the connecting ring 9. The scraper frame 10 is composed of a support rod and a silicone scraper. The silicone scraper is in contact with the inner wall of the mixing tank 1. The mixing tank 1 is also equipped with a concentration detection sensor assembly. The water pump assembly of the delivery pipe 4 is electrically connected to the concentration detection sensor assembly.

[0022] Working principle description: The concentration of the slurry in the mixing tank 1 is detected by a concentration detection sensor assembly. When the concentration is too high, an external water pump draws a fixed amount of water and delivers it to the tank through the delivery pipe 4. When the concentration is too low, slurry is added. This operation completes the slurry mixing process. During the mixing process, the motor 3 starts and drives the stirring rod 5 and the stirring paddle 6 to rotate, mixing the slurry in the tank. During normal mixing, the scraper frame 10 is stationary. The electric lifting seat 2 starts at regular intervals, driving the motor 3 and the stirring rod 5 to descend and adjust. The descent of the stirring rod 5 drives the gear 7 to descend into the connecting ring 9. Gear 7 meshes with the toothed block 11 on the inner wall of the connecting ring 9. When the stirring rod 5 and gear 7 rotate, the toothed block 11 drives the connecting ring 9 and the movable disc 8 to rotate, thereby driving the scraper frame 10 to rotate and scrape the inner wall of the mixing tank 1. Since the spacing of the toothed block 11 is greater than the spacing of the outer rack of gear 7, the rotation speed of the connecting ring 9 and the movable disc 8 is lower than the rotation speed of the stirring rod 5, so that the scraper frame 10 achieves a slow scraping effect, avoiding the generation of large noise while completing the scraping work. After scraping for a certain period of time, the electric lifting seat 2 drives the stirring rod 5 to rise again, causing gear 7 to disengage from the connecting ring 9, and the scraper frame 10 stops scraping.

[0023] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
