Description

Technical Field

[0001] This utility model relates to the field of tissue paper production technology, specifically a pulp mixing device for tissue paper production. Background Technology

[0002] Paper towels are an indispensable item in daily life, widely used for personal hygiene and cleaning in various homes and commercial settings. The main raw materials for paper towels are usually wood pulp or recycled paper. These raw materials need to undergo cleaning and bleaching before being put into production to ensure quality and hygiene. The prepared raw materials are put into a mixer, and the raw materials are thoroughly mixed with water to form a uniform pulp. This step is crucial for the quality of the subsequent paper, because a uniform pulp can ensure the consistency of performance indicators such as paper thickness, strength, and water absorption. When traditional pulp mixing devices are used, the upper liquid clumps are large, which requires a longer mixing time to mix the pulp evenly. These solids will affect the usability of the paper towels. In addition, during the pulping process, the trough is usually open for easy feeding, which makes the raw materials easy to splash and cause waste. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a pulp mixing device for paper towel production. By setting the feeding component and the mixing component away from the trough, the waste caused by raw material splashing can be avoided during the feeding process. At the same time, the contact area between the pulp and the outside world during the mixing process is reduced, reducing the amount of dust and other debris that drift into the mixing device and improving the comfort of using paper towels. By setting the mixing component, the raw materials are mixed from the loose raw materials when being mixed into pulp, reducing the pulping time and achieving the pulp quality requirements more quickly.

[0004] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0007] Preferably, a water injection pipe is fixedly connected to one side of the mixing tank, and a slurry outlet pipe is fixedly connected to one side of the mixing tank. A solenoid valve is fixedly installed inside the slurry outlet pipe.

[0008] Preferably, two connecting blocks are fixedly installed on the inner wall of the mixing tank, and a connecting groove is opened on one side of each connecting block. A limiting block is fixedly installed on the top of each connecting block.

[0009] Preferably, a fixing block is fixedly installed on both sides of the limiting block, and a baffle is rotatably connected between the two fixing blocks. A spring is fixedly connected to the bottom of the baffle and one side of the connecting block.

[0010] Preferably, a plurality of motors a are fixedly connected to the bottom of the partition, a rotating shaft a is driven and connected to the top of the motors a, and a plurality of stirring rods a are fixedly installed on the outside of the rotating shaft a.

[0011] Preferably, a plurality of motors b are fixedly connected to the bottom of the partition, a rotating shaft b is driven to the top of the motors b, and a plurality of stirring rods b are fixedly installed on the outside of the rotating shaft b.

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1-4 As shown, a pulp mixing device for paper towel production includes: a mixing tank 1, with a through groove on the top of the mixing tank 1, a partition 3 fixedly installed inside the mixing tank 1, and a feeding assembly disposed inside the mixing tank 1, the feeding assembly including: a connecting block 2, a connecting groove 201, a limiting block 202, a fixing block 203, a baffle 204, and a spring 205; and a mixing assembly disposed on the top of the partition 3, the mixing assembly including: a rotating shaft a302, a mixing rod a303, a rotating shaft b305, a mixing rod b306, a rotating shaft 402, and a threaded mixing blade 403.

[0024] By positioning the feeding components and keeping the mixing components away from the trough, waste caused by raw material splashing during the feeding process can be avoided. It also reduces the contact area between the pulp and the outside environment during the mixing process, reducing the amount of dust and other debris that can enter the mixing device and improving the comfort of using paper towels. The mixing components also ensure that the raw materials are mixed from a loose state rather than from lumps, reducing pulping time and allowing the pulp quality requirements to be met more quickly.

[0025] A water injection pipe 101 is fixedly connected to one side of the mixing tank 1, and a slurry outlet pipe 102 is fixedly connected to one side of the mixing tank 1. A solenoid valve 103 is fixedly installed inside the slurry outlet pipe 102. Before adding the raw materials to the mixing tank 1, the solenoid valve 103 is closed. First, pure water is added to the mixing tank 1 from the water injection pipe 101. After the slurry is mixed, the solenoid valve 103 is opened so that the slurry flows out from the slurry outlet pipe 102.

[0026] Two connecting blocks 2 are fixedly installed on the inner wall of the mixing tank 1. A connecting groove 201 is opened on one side of the connecting block 2. A limiting block 202 is fixedly installed on the top of the connecting block 2. A fixing block 203 is fixedly installed on both sides of the limiting block 202. A baffle 204 is rotatably connected between the two fixing blocks 203. A spring 205 is fixedly connected to the bottom of the baffle 204 and one side of the connecting block 2.

[0027] When adding materials, the raw materials are placed above the baffle 204. The baffle 204 is subjected to pressure from the raw materials, causing it to rotate downwards and compress the spring 205. The raw materials fall into the mixing tank 1 through the gap opened by the two baffles 204. After the raw materials fall, the pressure above the baffle 204 disappears, and the elastic force generated by the compression of the spring 205 pushes the baffle 204 upwards. The limiting block 202 can limit the baffle 204 to prevent it from flipping upwards. Through the baffle 204 and the spring 205, the crushed raw materials will not splash when mixing the slurry, and the falling of dust and other debris will also be reduced.

[0028] Among them, multiple motors a301 are fixedly connected to the bottom of the partition 3, and a rotating shaft a302 is driven to the top of the motors a301. Multiple stirring rods a303 are fixedly installed on the outside of the rotating shaft a302. Multiple motors b304 are fixedly connected to the bottom of the partition 3. A rotating shaft b305 is driven to the top of the motors b304. Multiple stirring rods b306 are fixedly installed on the outside of the rotating shaft b305. A motor storage box 4 is fixedly installed on the top of the partition 3. A motor c401 is fixedly installed inside the motor storage box 4. A rotating shaft 402 is driven to the top of the motor c401. A threaded stirring blade 403 is fixedly installed on the outside of the rotating shaft 402.

[0029] Before the raw materials are added, motor a301 rotates forward, driving rotating shaft a302 to rotate forward, and stirring rod a303 rotates together. Motor b304 rotates in reverse, driving rotating shaft b305 to rotate in reverse, and stirring rod b306 rotates in reverse. Motor c401 rotates, driving rotating shaft 402 to rotate, and simultaneously driving threaded stirring blade 403 to rotate. The falling lumpy raw materials are cut and dispersed by threaded stirring blade 403. The bulk raw materials are mixed into the water. Since stirring rod a303 and stirring rod b306 rotate in different directions, the water flow in the mixing tank 1 rotates in different directions. The opposite water flow impacts the raw materials, causing the raw materials to be dispersed by the water flow. The raw materials and water flow are mixed more evenly, which improves the flowability of the slurry in the mixing tank 1 and increases the rate of uniform mixing of the slurry.

[0030] Working principle:

[0031] Before adding the raw materials to the mixing tank 1, the solenoid valve 103 is closed. First, pure water is added to the mixing tank 1 through the water inlet pipe 101. After the slurry is mixed, the solenoid valve 103 is opened, allowing the slurry to flow out from the outlet pipe 102. When adding the raw materials, the raw materials are placed above the baffle 204. The baffle 204 is subjected to pressure from the raw materials, causing it to rotate downwards, thus squeezing the spring 205. The raw materials fall into the mixing tank 1 through the gap created by the movement of the two baffles 204. After the raw materials fall, the pressure above the baffle 204 disappears, and the elastic force generated by the compression of the spring 205 pushes the baffle 204 upwards. The limiting block 202 can limit the movement of the baffle 204, preventing it from flipping upwards. Through the baffle 204 and the spring 205, the raw materials that are broken down during the mixing process are kept in place. The material will not splash, and the amount of dust and other debris falling off will also be reduced. Before the material is added, the motor a301 rotates forward, driving the rotating shaft a302 to rotate forward, and the stirring rod a303 rotates together. The motor b304 rotates in reverse, driving the rotating shaft b305 to rotate in reverse, and the stirring rod b306 rotates in reverse. The motor c401 rotates, driving the rotating shaft 402 to rotate, and at the same time driving the threaded stirring blade 403 to rotate. The falling blocky material is cut and dispersed by the threaded stirring blade 403. The bulk material is mixed into the water. Since the stirring rods a303 and b306 rotate in different directions, the water flow in the mixing tank 1 rotates in different directions. The opposite water flow hits the material, causing the material to be dispersed by the water flow. The material and water flow are mixed more evenly, which improves the flowability of the slurry in the mixing tank 1 and increases the speed of slurry mixing.
