Description

Technical Field

[0001] This utility model relates to the field of double-sided offset paper processing technology, specifically to a pulp mixing device for double-sided offset paper processing. Background Technology

[0002] Offset paper is a type of paper in which adhesive is applied to both sides of the paper during the papermaking process to improve its surface properties. It has the characteristics of low extensibility, uniform ink absorption, good smoothness, dense and opaque texture, and strong water resistance. It is the first choice for various books and textbooks. In the processing of offset paper, a pulp mixing device is often required.

[0003] Existing pulp mixing devices for offset paper processing generally only mix the pulp to disperse fibers and improve their binding force. However, after mixing, the pulp easily clogs the discharge pipe, causing the mixed pulp to get stuck and preventing it from being discharged smoothly. This prolongs the production cycle and affects overall production efficiency. Pulp clogging may also cause the pulp to stay in the mixing tank for too long, affecting the uniformity and quality of the pulp. Utility Model Content

Through the operation of the auxiliary stirring device, the pulp will not adhere to the inner wall of the stirring tank.

[0010] Preferably, the inner wall of the rotating ring is fixedly connected to the outer wall of the stirring shaft, and the outer wall of the scraper is slidably connected to the inner wall of the mixing tank, so that the auxiliary stirring device can work at the same time as the stirring assembly, ensuring that the pulp is fully mixed during the stirring process.

[0011] Preferably, the discharge device includes a discharge pipe, a valve is fixedly connected inside the discharge pipe, a rotary motor is fixedly connected to the bottom of the discharge pipe, the output end of the rotary motor passes through the discharge pipe and is fixedly installed with a vortex fan, and a leak-proof plate is fixedly connected to the bottom of the inner wall of the discharge pipe.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a pulp mixing device for double-sided offset paper processing, comprising: a mixing tank 1, a support base 2 fixedly connected to the bottom of the mixing tank 1, a tank cover 3 fixedly connected to the top of the mixing tank 1, a feed inlet 4 fixedly connected to the inner wall of the tank cover 3, a mixing assembly 5 fixedly connected inside the mixing tank 1, an auxiliary mixing device 6 fixedly connected to the outer wall of the mixing assembly 5, and a discharge device 7 fixedly connected to the bottom of the mixing tank 1. Pulp and other materials are poured into the mixing tank 1 through the feed inlet 4, and then the pulp is mixed by the mixing assembly 5. While the mixing assembly 5 is working, the auxiliary mixing device 6 scrapes the inner wall of the mixing tank 1 to reduce the adhesion of the pulp to the inner wall of the mixing tank 1. After the pulp is mixed, the pulp inside the mixing tank 1 is discharged through the discharge device 7 to prevent the pulp from clogging the discharge pipe 70.

[0025] The mixing assembly 5 includes a drive motor 50, with a stirring shaft 51 fixedly connected to the output end of the drive motor 50. A stirring rod 52 is fixedly connected to the outer wall of the stirring shaft 51. The drive motor 50 is fixedly connected to the outer wall of the bucket lid 3. The end of the stirring shaft 51 away from the drive motor 50 passes through the bucket lid 3. When the drive motor 50 is started, the stirring shaft 51 rotates, causing the stirring shaft 51 to rotate with the stirring rod 52, thereby stirring the pulp inside the mixing bucket 1 and making the pulp inside the mixing bucket 1 mix quickly.

[0026] The auxiliary stirring device 6 includes a rotating ring 60, a connecting rod 61 fixedly connected to the outer wall of the rotating ring 60, a scraper 62 fixedly connected to the outer wall of the connecting rod 61, the inner wall of the rotating ring 60 fixedly connected to the outer wall of the stirring shaft 51, and the outer wall of the scraper 62 slidably connected to the inner wall of the mixing tank 1. When the stirring assembly 5 rotates, the scraper 62 will rotate accordingly, so that the pulp will not stick to the inner wall of the mixing tank 1, ensuring that the pulp is fully mixed during the stirring process.

[0027] The discharge device 7 includes a discharge pipe 70, with a valve 71 fixedly connected inside the discharge pipe 70. A rotary motor 72 is fixedly connected to the bottom of the discharge pipe 70. The output end of the rotary motor 72 passes through the discharge pipe 70 and is fixedly installed with a vortex fan 73. A leak-proof plate 74 is fixedly connected to the bottom of the inner wall of the discharge pipe 70. The top of the outer side of the discharge pipe 70 is fixedly connected to the bottom of the outer wall of the mixing tank 1. The outer wall of the leak-proof plate 74 is slidably connected to the outer wall of the bottom of the vortex fan 73. First, the valve 71 is opened to allow the pulp after mixing to enter the discharge pipe 70. Then, the rotary motor 72 is started to make the vortex fan 73 rotate. At the same time, the rotation of the vortex fan 73 will cause the pulp to be diverted and discharged from the discharge pipe 70, so that the pulp will not be blocked when passing through the discharge pipe 70, thus avoiding the phenomenon that blockage of the discharge pipe 70 leads to a longer production cycle and affects the overall production efficiency. The setting of the leak-proof plate 74 prevents the pulp from affecting the rotary motor 72 through the gap between the rotary motor 72 and the discharge pipe 70.

[0028] Working principle

[0029] In use, pulp and other materials are poured into the mixing tank 1 through the feed inlet 4, and then the pulp is stirred by the stirring component 5. While the stirring component 5 is working, the auxiliary stirring device 6 will scrape the inner wall of the mixing tank 1 to reduce the adhesion of the pulp to the inner wall of the mixing tank 1. After the pulp is stirred, the pulp inside the mixing tank 1 is discharged through the discharge device 7 to avoid the pulp clogging the discharge pipe 70.

[0030] When it is necessary to stir the pulp, first place the device on a relatively stable ground so that the support base 2 supports the device. Then, pour the pulp and other materials into the mixing tank 1 through the feed port 4 at the top of the lid 3. Start the drive motor 50 to make the stirring shaft 51 rotate, which in turn makes the stirring shaft 51 rotate with the stirring rod 52 to stir the pulp inside the mixing tank 1. At the same time, the rotation of the stirring shaft 51 will drive the rotating ring 60 to rotate, so that the connecting rod 61 and the scraper 62 slide on the inner wall of the mixing tank 1, which prevents the pulp from sticking to the inner wall of the mixing tank 1 and ensures that the pulp is fully mixed during the stirring process.

[0031] When it is necessary to discharge the mixed pulp from the mixing tank 1, first open valve 71 to allow the mixed pulp to enter the discharge pipe 70, then start the rotary motor 72 to make the vortex fan 73 rotate. At the same time, the rotation of the vortex fan 73 will cause the pulp to be diverted and discharged from the discharge pipe 70, so that the pulp will not be blocked when passing through the discharge pipe 70. The anti-leakage plate 74 is set to prevent the pulp from affecting the rotary motor 72 through the gap between the rotary motor 72 and the discharge pipe 70. This avoids the phenomenon that the pulp stays in the mixing tank 1 for too long after being blocked, thus affecting the uniformity and quality of the pulp.
