Description

Technical Field

[0001] The utility model relates to the technical field of facial tissue paper, in particular to a raw material pretreatment device for facial tissue paper production. Background Art

[0002] The production process of facial tissue is generally divided into several steps, including pulp preparation, papermaking, cutting, and packaging. The first step is pulp preparation, which requires cork powder, various leathers and hemps, grain crop by-products and other raw materials to be stirred and heated to make pulp.

[0003] Pulp preparation usually uses a pulping machine, which uses a spiral stirring paddle to stir the mixture of raw material powder and water and heat it to stir the mixture into a slurry with a certain concentration. In actual use, the single rotation mode of the stirring paddle makes the slurry preparation efficiency low. In addition, due to the high temperature of the mixed liquid, the wood material in the raw material is prone to fermentation when heated, producing a large number of bubbles. These bubbles gather around the pulping machine as the stirring paddle rotates to form foam, which affects the discharge of the material and is easy to overflow the pulping machine, causing pollution to external equipment. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a raw material pretreatment device for facial tissue production.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A raw material pretreatment device for facial tissue production includes a pulping barrel and a stirring paddle. The pulping barrel is a cylindrical barrel structure. A mounting plate is across the top of the pulping barrel. A tooling frame is fixedly arranged at the center of the mounting plate. A driving motor is fixedly arranged on the tooling frame. The output shaft of the driving motor passes through the mounting plate and the end shaft of the output shaft is connected to a linkage mechanism. A stirring paddle is arranged between the linkage mechanism and the bottom of the pulping barrel, and adjustment mechanisms are arranged on both sides of the stirring paddle.

[0007] Preferably, an overflow port is provided on the top side wall of the pulping barrel, and a discharge pipe is provided at the bottom of the pulping barrel, and an outlet pipe of the discharge pipe is connected to an external pulp pump.

[0008] Preferably, four connecting columns are fixedly connected to the lower end of the mounting plate, a circular plate is fixedly connected to the bottom end of the connecting column, and an annular groove is provided on the outer ring of the circular plate.

[0009] Preferably, the linkage mechanism includes a driving gear, a driven gear and a ring gear. The terminal shaft of the driving motor output shaft is connected to the driving gear rotatably installed in the center of the circular plate. The driving gear is symmetrically meshed with driven gears rotatably installed on the circular plate on both sides. The outer sides of the two driven gears are meshed with ring gears. The bottom ends of the two driven gears are fixedly connected to a rotating column that passes through the circular plate.

[0010] Preferably, four inverted L-shaped blocks are evenly arranged on the outer wall of the ring gear, and a debubble mechanism is installed at the bottom end of each inverted L-shaped block.

[0011] Preferably, the debubble mechanism includes a fixed block and a debubble plate. The fixed block is installed at the bottom end of the inverted L-shaped block. A sliding groove is opened on the side of the fixed block away from the ring gear. An electric slider is slidably connected in the sliding groove. The side wall of the electric slider is fixedly connected to the rectangular debubble plate.

[0012] Preferably, the stirring paddles are fixedly connected to the bottom of the rotating column, the two stirring paddles are relatively vertical, and connecting plates are symmetrically arranged on both sides of the stirring paddles.

[0013] Preferably, the adjustment mechanism includes a gas spring and an adjustment plate, and a number of evenly distributed adjustment plates are rotatably connected between each group of connecting plates. The telescopic end of the gas spring is rotatably connected to the bottom of the adjustment plate. Grooves are provided on the connecting plates on both sides of the bottom of the adjustment plate, and the fixed end of the gas spring is rotatably connected to the inner wall of the groove.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model provides a stirring paddle and an adjustment mechanism. Compared with the traditional single-screw stirring method, the two relatively vertical and synchronously rotating stirring paddles can enhance the stirring effect, fully mix the slurry, and improve the stirring efficiency. The adjustment plate that can be subjected to a greater reaction force as the driving motor power increases can adaptively adjust the inclination angle. When the driving motor power increases, the gas spring is compressed, and the vertical angle of the adjustment plate is reduced, so that the adjustment plate is in more complete contact with the slurry, thereby improving the stirring effect of the stirring paddle. When the driving motor power decreases, the gas spring extends, and the adjustment plate returns to the initial position, which can increase the fluidity of the slurry. This arrangement can generate different stirring forces at different stages in the slurry preparation process, and combined with the slurry completion degree, it can effectively improve the slurry preparation efficiency and the slurry quality, thus laying a foundation for the subsequent production of facial tissue paper.

[0016] The utility model provides a defoaming mechanism, and the defoaming mechanism and the stirring paddle share a driving motor as a power, which saves space and can ensure that the defoaming mechanism and the stirring paddle work synchronously to break the foam. The heated slurry is prone to foam as the stirring proceeds. The height position of the defoaming plate can be adjusted by controlling the sliding of the electric slider, and the foam layers of different thicknesses can be effectively broken to prevent the foam from overflowing from the pulping barrel and polluting external equipment as it grows over time.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Reference Figure 1-7A raw material pretreatment device for facial tissue production includes a pulping barrel 1 and a stirring paddle 9. The pulping barrel 1 is a cylindrical barrel structure. A mounting plate 2 is spanned across the top of the pulping barrel 1. A tooling frame 3 is fixedly arranged at the center of the mounting plate 2. A driving motor 5 is fixedly arranged on the tooling frame 3. The output shaft of the driving motor 5 passes through the mounting plate 2 and the end shaft of the output shaft is connected to a linkage mechanism 61. A stirring paddle 9 is arranged between the linkage mechanism 61 and the bottom of the pulping barrel 1. Adjustment mechanisms 11 are arranged on both sides of the stirring paddle 9. The driving motor 5 and the linkage mechanism 61 are respectively mounted on the tooling frame 3 above the mounting plate 2 and the circular plate 201 below the mounting plate 2. The stirring paddle 9 is driven to rotate by the driving motor 5. The linkage mechanism 61 can drive the defoaming mechanism 17 to work simultaneously when the stirring paddle 9 rotates. The adjustment mechanism 11 can adaptively adjust the working efficiency of the stirring paddle 9 according to the power of the driving motor 5, which is conducive to fully and effectively mixing the raw materials into qualified slurry.

[0027] As a technical optimization solution of the utility model, an overflow port 102 is provided on the top side wall of the pulping barrel 1, and a discharge pipe 101 is provided at the bottom of the pulping barrel 1. The outlet pipe of the discharge pipe 101 is connected to an external pulp pump. The overflowed slurry can overflow from the overflow port 102 and be collected to prevent the slurry from overflowing and polluting external equipment. The stirred slurry is pumped out from the discharge pipe 101 by the external pulp pump.

[0028] As a technical optimization solution of the utility model, four connecting columns 4 are fixedly connected to the lower end of the mounting plate 2, and a circular plate 201 is fixedly connected to the bottom end of the connecting column 4. An annular groove is provided on the outer ring of the circular plate 201. The connecting column 4 is used to connect the mounting plate 2 and the circular plate 201, and the annular groove is used to install the annular gear 15, so that the sliding block at the bottom of the annular gear 15 is slidably connected in the annular groove.

[0029] As a technical optimization solution of the utility model, the linkage mechanism 61 includes a driving gear 6, a driven gear 7 and a ring gear 15. The terminal shaft of the output shaft of the driving motor 5 is connected to the driving gear 6 rotatably mounted at the center of the circular plate 201. The two sides of the driving gear 6 are symmetrically meshed with driven gears 7 rotatably mounted on the circular plate 201. The outer sides of the two driven gears 7 are meshed with ring gears 15. The bottom ends of the two driven gears 7 are fixedly connected to a rotating column 8 that penetrates the circular plate 201. Using gears to connect the driving motor 5 and the rotating column 8 can make the two rotating columns 8 rotate synchronously, which is convenient for the synchronous rotation of the two stirring paddles 9 without interfering with each other. The ring gear 15 rotates using the driven gear 7, and the driving motor 5 is used as power together to save space.

[0030] As a technical optimization solution of the utility model, four inverted L-shaped blocks 16 are evenly arranged on the outer wall of the ring gear 15, and a defoaming mechanism 17 is installed at the bottom of each inverted L-shaped block 16. The defoaming mechanism 17 works synchronously with the operation of the driving motor 5, and can effectively break the foam on the surface of the slurry, and can replace components of different specifications or functions according to the needs of actual use to perform the work of defoaming or collecting foam floating objects.

[0031] As a technical optimization solution of the utility model, the defoaming mechanism 17 includes a fixed block 18 and a defoaming plate 21. The fixed block 18 is installed at the bottom of the inverted L-shaped block 16. A slide groove 19 is provided on the side of the fixed block 18 away from the ring gear 15. An electric slider 20 is slidably connected in the slide groove 19. The side wall of the electric slider 20 is fixedly connected to a rectangular defoaming plate 21. The heated slurry is prone to foaming as it is stirred. By controlling the sliding of the electric slider 20, the height position of the defoaming plate 21 can be adjusted, and the foam layers of different thicknesses can be effectively broken to prevent the foam from overflowing the pulping barrel 1 over time and contaminating external equipment.

[0032] As a technical optimization solution of the utility model, a rectangular stirring paddle 9 with a hollow hole is fixedly connected to the bottom of the rotating column 8, the two stirring paddles 9 are relatively vertical, and connecting plates 10 are symmetrically arranged on both sides of the stirring paddles 9. Compared with the traditional single-screw stirring method, the two relatively vertical and synchronously rotating stirring paddles 9 can enhance the stirring effect, fully mix the slurry, and improve the stirring efficiency.

[0033] As a technical optimization solution of the utility model, the adjustment mechanism 11 includes a gas spring 13 and an adjustment plate 14. A plurality of evenly distributed adjustment plates 14 are rotatably connected between each group of connecting plates 10. The bottom of the adjustment plate 14 is rotatably connected to the telescopic end of the gas spring 13. The connecting plates 10 on both sides of the bottom of the adjustment plate 14 are provided with grooves 12, and the fixed end of the gas spring 13 is rotatably connected to the inner wall of the groove 12. The adjustment plate 14, which can be subjected to a greater reaction force as the power of the driving motor 5 increases, can adaptively adjust the inclination angle. When the power of the driving motor 5 increases, the gas spring 13 is compressed, and the vertical angle of the adjustment plate 14 is reduced, so that the adjustment plate 14 is more fully in contact with the slurry, and the stirring effect of the stirring paddle 9 is improved. When the power of the driving motor 5 decreases, the gas spring 13 is extended, and the adjustment plate 14 returns to the initial position, which can increase the fluidity of the slurry.

[0034] When the utility model is used, the staff puts the raw material powder into the pulping barrel 1 according to the amount and adds the water of the appropriate proportion. The overflowing slurry overflows from the overflow port 102 and is collected. The driving motor 5 is started, and the driving motor 5 rotates to drive the driving gear 6 to rotate. The two driven gears 7 meshing with the driving gear 6 follow and the ring gear 15 meshing with the driven gear 7 also rotates. When the two driven gears 7 rotate, the two rotating columns 8 rotate, driving the two stirring paddles 9 to rotate alternately and stir the mixed slurry. During the stirring process of the stirring paddles 9, the adjusting plate 14 is subjected to a force opposite to the rotation direction. When the output power of the driving motor 5 is increased, the reaction force on the adjusting plate 14 increases, the gas spring 13 is forced to shrink, and the bottom of the adjusting plate 14 slides along the groove 12, so that the vertical angle of the adjusting plate 14 is reduced, and the annular gear 15 rotates to drive the inverted L-shaped block 16 to make a circular motion, so that the four debubbling plates 21 rotate continuously around the center of the annular gear 15 and break the foam on the liquid surface. If the liquid level is different, the electric slider 20 can be controlled to slide up and down in the slide 19 to adjust the height position of the debubbling plate 21, and the stirred slurry is pumped out from the discharge pipe 101 by an external pulp pump.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
