Description

TECHNICAL FIELD

[0001] The utility model relates to the field of adhesive tape base paper production, especially to a paper pulp sizing device based on adhesive tape base paper production. BACKGROUND

[0002] Adhesive tape base paper refers to the base paper used for adsorbing adhesive when manufacturing adhesive tape. In the production process of adhesive tape base paper, sizing agent needs to be added to the paper pulp to make the fibers in the paper pulp adsorb sizing agent.

[0003] In the sizing process of the existing sizing device, the sizing agent is usually directly added to the surface of the paper pulp, and then the paper pulp is stirred to mix the paper pulp and the sizing agent. In the actual sizing process, the paper pulp and the sizing agent are prone to uneven mixing, which causes the paper pulp in some parts to not be fully mixed with the sizing agent, thereby resulting in poor quality of the output adhesive tape base paper. UTILITY MODEL CONTENT

[0004] In order to overcome the above-mentioned shortcomings, the utility model provides a paper pulp sizing device based on adhesive tape base paper production, which can uniformly add sizing agent to the inside of the paper pulp, so that the fibers in the paper pulp can more uniformly adsorb the sizing agent.

[0005] The technical scheme is as follows: a paper pulp sizing device based on adhesive tape base paper production, comprising a mounting frame, an inlet pipe, an outlet pipe, a connecting ring, a servo motor, and a flow guide assembly. The mounting frame has an inlet pipe fixedly connected to the middle part, an outlet pipe fixedly connected to the middle part, a connecting ring rotatably connected between the inlet pipe and the outlet pipe, a servo motor fixedly connected to the upper part of the inlet pipe, and a flow guide assembly arranged on the connecting ring.

[0006] As a further preferred scheme, the flow guide assembly comprises a spur gear, a spur gear ring, a flow guide ring, a rotating ring, a straight pipe, and an outlet pipe. The output shaft of the servo motor is fixedly connected with the spur gear, the connecting ring is fixedly connected with the spur gear ring, the spur gear ring is engaged with the spur gear, the mounting frame is fixedly connected with the flow guide ring, the rotating ring is rotatably connected to the inner side of the flow guide ring, four straight pipes are slidably connected to the rotating ring, and four outlet pipes are fixedly connected to the connecting ring. The outlet pipes are slidably connected with the straight pipes.

[0007] As a further preferred scheme, a plurality of outlet ports are formed on each outlet pipe, and the outlet ports on the outlet pipes are used to discharge the sizing agent.

[0008] As a further preferred embodiment, it also includes an extrusion assembly. The extrusion assembly is provided on the straight pipe and connected to the discharge pipe. The extrusion assembly includes a push rod, a one-way valve, a two-way valve, and an extrusion frame. A push rod is fixedly connected to each straight pipe, a one-way valve is fixedly connected to the inside of each straight pipe, and a one-way valve is fixedly connected to the middle of the inside of each discharge pipe. Several discharge ports on the discharge pipe are located on the side of the one-way valve away from the straight pipe. An extrusion frame is fixedly connected to the slurry inlet pipe. An extrusion groove is opened on the extrusion frame, and the push rod is located in the extrusion groove on the extrusion frame.

[0009] As a further preferred option, the extrusion groove on the extrusion frame is used to extrude the push rod.

[0010] As a further preferred option, it also includes a stirring frame, with four stirring frames fixed to the inside of the connecting ring.

[0011] This invention has the following advantages: the sizing agent inside the guide ring is introduced into the pulp inside the pulp inlet pipe, connecting ring and outlet pipe through the straight pipe and discharge pipe. The discharge pipe can penetrate deep into the pulp and rotates during the discharge of the sizing agent, which can promote more thorough mixing of the sizing agent and the pulp, so that the fibers inside the pulp can more evenly absorb the sizing agent, thereby improving the quality of the tape base paper.

[0012] The straight tube drives the discharge tube, push rod, one-way valve one, and one-way valve two to rotate. The extrusion groove on the extrusion frame squeezes the push rod to move back and forth in the direction away from or towards the discharge tube. The push rod drives the straight tube and one-way valve one to move back and forth. Each time the straight tube and one-way valve one move back and forth, a certain amount of sizing agent will be discharged into the pulp through one-way valve two and the discharge tube. In this way, the sizing agent is discharged into the pulp more evenly. This process is repeated. When the discharge tube rotates, the sizing agent can be intermittently discharged through the discharge port on the discharge tube into the pulp inlet tube, pulp outlet tube, and the pulp inside the connecting ring. This further promotes more thorough mixing of the sizing agent with the pulp and allows the fibers inside the pulp to more evenly absorb the sizing agent.

[0013] The connecting ring drives the agitator to rotate, and the agitator agitates the pulp inside the pulp inlet pipe, connecting ring, and pulp outlet pipe, further promoting a more thorough mixing of the sizing agent and pulp. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0020] Example 1: A pulp sizing device based on adhesive tape base paper production, such as Figures 1-4 As shown, it includes a mounting frame 1, a slurry inlet pipe 2, a slurry outlet pipe 3, a connecting ring 4, a servo motor 5, and a flow guiding assembly. The slurry inlet pipe 2 is welded to the middle of the mounting frame 1, and the slurry outlet pipe 3 is welded to the middle of the mounting frame 1. The slurry inlet pipe 2 and the slurry outlet pipe 3 are rotatably connected by a connecting ring 4. The servo motor 5 is bolted to the upper part of the slurry inlet pipe 2, and the flow guiding assembly is provided on the connecting ring 4.

[0021] The flow guiding assembly includes a spur gear 6, a spur gear ring 7, a flow guiding ring 8, a rotating ring 9, a straight pipe 10, and a discharge pipe 11. The output shaft of the servo motor 5 is connected to the spur gear 6 via a flat key. The spur gear ring 7 is fixedly connected to the connecting ring 4 and meshes with the spur gear 6. The flow guiding ring 8 is welded to the mounting bracket 1. The rotating ring 9 is rotatably connected to the inner side of the flow guiding ring 8. Four straight pipes 10 are slidably connected to the rotating ring 9. Four discharge pipes 11 are fixedly connected to the connecting ring 4. Each discharge pipe 11 has several discharge ports. The discharge ports on the discharge pipe 11 are used to discharge the adhesive. The discharge pipe 11 is slidably connected to the straight pipe 10.

[0022] Each discharge pipe 11 has several discharge ports, which are used to discharge the sizing agent.

[0023] Initially, workers add sizing agent to the guide ring 8, filling it completely. Then, they feed pulp for the tape base paper into the inlet pipe 2. The pulp passes through the inlet pipe 2, connecting ring 4, and outlet pipe 3 sequentially. Next, the worker starts the output shaft of the servo motor 5, which drives the spur gear 6. The spur gear 6 drives the connecting ring 4, spur gear ring 7, rotating ring 9, straight pipe 10, and outlet pipe 11. The sizing agent inside the guide ring 8 is fed into the pulp inside the inlet pipe 2, connecting ring 4, and outlet pipe 3 through the straight pipe 10 and outlet pipe 11. The outlet pipe 11 can penetrate deep into the pulp, and it rotates during the discharge process, promoting more thorough mixing of the sizing agent and pulp. This allows the pulp fibers to absorb the sizing agent more evenly, thus improving the quality of the tape base paper.

[0024] Example 2: Based on Example 1, such as Figures 1-4 As shown, it also includes an extrusion assembly. The extrusion assembly is provided on the straight pipe 10 and is connected to the discharge pipe 11. The extrusion assembly includes a push rod 12, a one-way valve 13, a two-way valve 14 and an extrusion frame 15. A push rod 12 is welded on each straight pipe 10. A one-way valve 13 is fixed to the inside of each straight pipe 10. A one-way valve 14 is fixed to the middle of the inside of each discharge pipe 11. Several discharge ports on the discharge pipe 11 are located on the side of the one-way valve 14 away from the straight pipe 10. An extrusion frame 15 is provided on the slurry inlet pipe 2. An extrusion groove is opened on the extrusion frame 15. The push rod 12 is located in the extrusion groove on the extrusion frame 15.

[0025] The extrusion groove on the extrusion frame 15 is used to extrude the push rod 12.

[0026] When the spur gear 6 drives the connecting ring 4, spur gear ring 7, rotating ring 9, and straight pipe 10, the straight pipe 10 drives the discharge pipe 11, push rod 12, one-way valve 13, and one-way valve 2 14 to rotate. The extrusion groove on the extrusion frame 15 extrudes the push rod 12, which moves back and forth towards the discharge pipe 11. The push rod 12 drives the straight pipe 10 and one-way valve 13 to move back and forth. When one-way valve 13 moves towards one-way valve 2 14, the adhesive between one-way valve 13 and one-way valve 2 14 is discharged through one-way valve 2 14. Then, the adhesive is discharged through the outlet on the discharge pipe 11. When one-way valve 13 moves away from one-way valve 2 14, the one-way valve 2 14 and the one-way valve on the inside of the discharge pipe 11 are connected. As the cavity between valves 11 and 13 increases, under negative pressure, the sizing agent on the side of valve 13 away from valve 214 enters the space between valve 13 and valve 214 through valve 13. Each time the straight pipe 10 and valve 13 move back and forth, a certain amount of sizing agent is discharged into the pulp through valve 214 and discharge pipe 11. This further distributes the sizing agent more evenly into the pulp. As the discharge pipe 11 rotates, the sizing agent can be intermittently discharged through the outlet on the discharge pipe 11 into the pulp inside the inlet pipe 2, outlet pipe 3 and connecting ring 4, further promoting a more thorough mixing of the sizing agent and the pulp, and further enabling the fibers inside the pulp to more evenly adsorb the sizing agent.

[0027] Example 3: Based on Example 2, such as Figure 2 and Figure 3 As shown, it also includes a stirring frame 16, and four stirring frames 16 are welded to the inner side of the connecting ring 4.

[0028] When the connecting ring 4 rotates, it drives the agitator 16 to rotate. The agitator 16 agitates the pulp inside the pulp inlet pipe 2, the connecting ring 4, and the pulp outlet pipe 3, further promoting a more thorough mixing of the sizing agent and the pulp.

[0029] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
