Description

Technical Field

[0001] This utility model relates to the field of wood crushing technology, and in particular to a wood processing equipment for papermaking. Background Technology

[0002] Paper is an indispensable item in our daily lives; whether reading, writing, or drawing, we cannot do without it. It also plays a vital role in industrial, agricultural, and defense production. Today, it's simply unimaginable to live without paper. As a powerful tool and material, paper plays a crucial role in exchanging ideas, disseminating culture, and developing science, technology, and production. It is a sheet-like fibrous product used for writing, printing, drawing, or packaging. Generally, paper is made by interlacing an aqueous suspension of pulped plant fibers on a wire mesh, initially dehydrating it, and then compressing and drying it. The raw material for paper—plant fibers—needs to be crushed into small particles using crushing equipment before further pulping.

[0003] Traditional crushing equipment often uses a double-roller counter-rotating method to crush wood. In practical applications, because the double rollers rotate at the same speed in opposite directions, the squeezing and pushing effect on the material is relatively fixed, which cannot process large amounts of material in a timely and effective manner, thus easily causing blockages. Moreover, when the double rollers rotate at the same speed in opposite directions, the force situation of the wood between the two rollers is quite complex. The degree of squeezing and crushing of wood in different parts and with different shapes may vary. In particular, due to factors such as the difference in linear velocity between the edge and center of the rollers, the size of the crushed wood particles is easily inconsistent. To address these issues, a wood processing equipment for papermaking is proposed. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a wood processing device for papermaking, which aims to improve the problem that the high breakage rate of wood fibers is easily caused by the same-speed counter-rotation in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wood processing device for papermaking, comprising a base plate, a feeding frame fixedly connected to the top of the base plate, a motor fixedly connected to the left side of the top of the base plate, a drive shaft fixedly connected to the drive end of the motor, a main shaft wheel fixedly connected to the outside of the drive shaft, a roller frame fixedly connected to the top of the feeding frame, a main crushing roller rotatably connected to the middle of the roller frame, a driven shaft wheel fixedly connected to the end of the main crushing roller near the motor, a first gear fixedly connected to the end of the main crushing roller away from the motor, a driven crushing roller rotatably connected to the middle of the roller frame, a second gear fixedly connected to the end of the driven crushing roller away from the motor, a support block fixedly connected to the end of the roller frame away from the motor, a gear roller rotatably connected to the middle of the support block, and a swinging component for screening crushed wood fixedly connected to the end of the drive shaft away from the motor;

[0006] As a further description of the above technical solution:

[0007] The swing assembly includes a through groove, which is located in the middle of the unloading frame. A transmission plate is slidably connected to the middle of the through groove. A filter screen is fixedly connected to the middle of the transmission plate. A U-shaped tube is fixedly connected to the end of the transmission plate near the motor. A clamping roller is fixedly connected to both the front and rear sides of the U-shaped tube. A corrugated pipe is fixedly connected to the end of the drive shaft away from the motor. L-shaped baffles are fixedly connected to both the front and rear sides of the transmission plate. An elastic cloth is fixedly connected to the side of the L-shaped baffle near the unloading frame. A spring is fixedly connected to the middle of the side of the L-shaped baffle near the unloading frame.

[0008] As a further description of the above technical solution:

[0009] A belt is fitted around the outside of the main shaft wheel, and the belt is fitted around the outside of the driven shaft wheel.

[0010] As a further description of the above technical solution:

[0011] A protective cover is fixedly connected to the end of the roller frame away from the motor. The outer teeth of the gear roller are meshed with the outer teeth of the first face gear, and the outer teeth of the gear roller are meshed with the outer teeth of the second face gear.

[0012] As a further description of the above technical solution:

[0013] The end of the elastic fabric near the motor is fixedly connected to the end of the feed rack away from the motor, and the end of the spring away from the L-shaped baffle is fixedly connected to the end of the feed rack away from the motor.

[0014] As a further description of the above technical solution:

[0015] The outer side of the roller is slidably connected to the outer side of the bellows, and the inner side of the U-shaped tube is slidably connected to the outer side of the bellows.

[0016] As a further description of the above technical solution:

[0017] A retaining bar is fixedly connected to the top end of the base plate away from the motor. A collection box is slidably connected to the outside of the retaining bar, and the bottom end of the collection box is slidably connected to the top end of the base plate.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, the main crushing roller is indirectly driven to rotate by a motor drive belt, so that the first gear connected to the other end of the main crushing roller can drive the second gear to rotate through the gear roller, so that the main crushing roller and the driven crushing roller rotate relative to each other. This reduces the probability of fiber breakage during the crushing process of the relatively rotating crushing rollers in the prior art, thereby more effectively maintaining the length and strength of the fibers. Furthermore, by reasonably setting the size ratio of the first gear to the second gear, a certain speed difference is formed between the main crushing roller and the driven crushing roller. The generation of this speed difference enhances the effect of lamination crushing, making the size of the crushed wood particles uniform.

[0020] 2. In this utility model, the bellows is driven to rotate by the drive shaft. The bellows indirectly drives the transmission plate to swing left and right by inertia through the external wave groove, so that the falling wood chips and wood ash move to the right and are screened by the filter screen, which effectively prevents material blockage and improves papermaking quality.

[0028] 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.

[0029] Reference Figures 1 to 3 This utility model provides an embodiment of a wood processing device for papermaking, comprising a base plate 1. The base plate 1 serves as the load-bearing foundation of the entire device and is made of 20 mm thick Q235 hot-rolled steel plate. This material has good strength and toughness, and can stably bear various loads during the operation of the device. A feeding rack 2 is fixedly connected to the top of the base plate 1. The feeding rack 2 consists of a support frame and a hopper-shaped shell. A motor 3 is fixedly connected to the left side of the top of the base plate 1, providing the power source for the operation of the device. A drive shaft 4 is fixedly connected to the drive end of the motor 3. The drive end of the motor 3 is rigidly connected to the drive shaft 4 through a standard flexible coupling, ensuring that power can be stably and efficiently transmitted to the drive shaft 4. A main shaft wheel 5 is fixedly connected to the outside of the drive shaft 4, and the main shaft wheel 5 is driven to rotate by the drive shaft 4.

[0030] refer to Figure 2 , Figure 3 A roller frame 7 is fixedly connected to the top of the feeding frame 2. The roller frame 7 is a key structure for supporting and fixing the crushing roller, and has four holes on both the left and right sides. The main crushing roller 8 is rotatably connected to the middle of the roller frame 7. The main crushing roller 8 is forged from high-strength alloy steel and its surface has undergone a special heat treatment process. A driven shaft wheel 9 is fixedly connected to the end of the main crushing roller 8 closest to the motor 3. A belt 6 is sleeved on the outside of the main shaft wheel 5, and the belt 6 is sleeved on the outside of the driven shaft wheel 9. The belt 6 is sleeved on the outer annular groove of the main shaft wheel 5, and its other end is sleeved on the outside of the driven shaft wheel 9, thereby realizing the transmission of the rotation of the main shaft wheel 5 to the driven shaft wheel 9.

[0031] A first gear 10 is fixedly connected to the end of the main crushing roller 8 away from the motor 3. The first gear 10 is located on the right side of the roller frame 7 and is parallel to the main crushing roller 8. A secondary crushing roller 11 is rotatably connected to the middle of the roller frame 7. The secondary crushing roller 11 is made of the same material and manufactured using the same process as the main crushing roller 8 to ensure that it has good crushing performance.

[0032] A second gear 12 is fixedly connected to the end of the crushing roller 11 away from the motor 3. The material and heat treatment process of the second gear 12 are the same as those of the first gear 10, only the size is different. This allows the main crushing roller 8 and the driven crushing roller 11 to achieve a speed difference when rotating. When the user feeds papermaking wood between the main crushing roller 8 and the driven crushing roller 11, this speed difference can accelerate the crushing effect and enhance the shearing, kneading and tearing action between the wood fibers, making the wood more thoroughly crushed. A support block 13 is fixedly connected to the end of the roller frame 7 away from the motor 3. There are two support blocks 13, located at the front and rear positions on one side of the roller frame 7.

[0033] A gear roller 14 is rotatably connected to the middle of the support block 13. The outer teeth of the gear roller 14 mesh with the outer teeth of the first gear 10 and the outer teeth of the second gear 12. The first gear 10 drives the gear roller 14 to rotate through the meshing of its teeth, and the gear roller 14 in turn drives the second gear 12 to rotate, thereby causing the crushing roller 11 to rotate. A protective cover 15 is fixedly connected to the end of the roller frame 7 away from the motor 3. The function of the protective cover 15 is to prevent wood chips from entering the area of ​​the second gear 12 during the wood crushing process, which could cause the teeth to jam.

[0034] refer to Figure 3 - Figure 5 The end of the drive shaft 4 furthest from the motor 3 is fixedly connected to a swing assembly for screening the crushed wood. The swing assembly includes a through groove 16, which is located in the middle of the unloading rack 2. A transmission plate 17 is slidably connected to the middle of the through groove 16, providing space for the transmission plate 17 to slide. A filter screen 18 is fixedly connected to the middle of the transmission plate 17. The filter screen 18 is made of woven stainless steel wire, and the mesh size can be customized according to actual production needs. The function of the filter screen 18 is to screen the crushed wood chips and wood ash, separating the wood ash from the wood chips.

[0035] A U-shaped tube 19 is fixedly connected to one end of the transmission plate 17 near the motor 3. Rollers 20 are fixedly connected to both the front and rear sides of the U-shaped tube 19. The U-shaped tube 19 is made of stainless steel, possessing a certain strength and flexibility. Rollers 20 are fixedly connected to the front and rear sides of the U-shaped tube 19 via pins. The rollers 20 are made of alloy steel and have undergone surface quenching treatment. A corrugated pipe 21 is fixedly connected to the end of the drive shaft 4 away from the motor 3. The outer side of the rollers 20 is slidably connected to the outer side of the corrugated pipe 21, and the inner side of the U-shaped tube 19 is slidably connected to the outer side of the corrugated pipe 21. When the drive shaft 4 rotates continuously, it drives the corrugated pipe 21 to rotate in the same direction. As the corrugated pipe 21 rotates, the rollers 20 repeatedly oscillate left and right along the corrugated groove pattern of the corrugated pipe 21, thereby pulling the transmission plate 17 to repeatedly oscillate left and right through the U-shaped tube 19.

[0036] L-shaped baffles 22 are fixedly connected to both the front and rear sides of the conveyor plate 17. An elastic cloth 23 is fixedly connected to the side of the L-shaped baffle 22 closest to the unloading rack 2, and is glued to the side of the L-shaped baffle 22 closest to the unloading rack 2. The elastic cloth 23 is made of high-strength rubber cloth and has good elasticity and flexibility. The end of the elastic cloth 23 closest to the motor 3 is fixedly connected to the end of the unloading rack 2 furthest from the motor 3. The elastic cloth 23 can stretch and contract with the oscillation of the conveyor plate 17. A spring 24 is fixedly connected to the middle of the side of the L-shaped baffle 22 closest to the unloading rack 2. The end of the spring 24 furthest from the L-shaped baffle 22 is fixedly connected to the end of the unloading rack 2 furthest from the motor 3. The spring 24 is bolted to the middle of the side of the L-shaped baffle 22 closest to the unloading rack 2. The spring 24 is made of high-quality spring steel and has a suitable elastic coefficient. The end of the spring 24 away from the L-shaped baffle 22 is fixedly connected to the end of the feed rack 2 away from the motor 3, which also serves to increase the swing inertia of the transmission plate 17.

[0037] A retaining strip 25 is fixedly connected to the top end of the base plate 1, away from the motor 3. The retaining strip 25, made of channel steel, is welded and fixed to the middle right side of the top of the base plate 1 and serves to guide and position the collection box 26. The collection box 26 is slidably connected to the outside of the retaining strip 25. The bottom end of the collection box 26 is slidably connected to the top of the base plate 1, allowing it to slide along the retaining strip 25 along the top of the base plate 1. It has sufficient volume to collect the screened wood ash, facilitating subsequent centralized processing and transportation.

[0038] Working principle: In use, the motor 3 is started in advance, and the motor 3 drives the main shaft wheel 5 to rotate through the transmission shaft 4. The main shaft wheel 5 pulls the driven shaft wheel 9 to rotate through the belt 6. After the driven shaft wheel 9 rotates, it pulls the main crushing roller 8 to rotate around the middle of the roller frame 7. After the main crushing roller 8 rotates, it drives the first gear 10 fixed at the other end of the main crushing roller 8 to rotate. The rotation of the first gear 10 drives the gear roller 14 to rotate through the tooth meshing. The gear roller 14 drives the second gear 12 fixed to the driven crushing roller 11 on the side of the main crushing roller 8 to rotate. At this time, since the first gear 10 and the second gear 12 are different in size, when the user feeds wood between the main crushing roller 8 and the driven crushing roller 11, the main crushing roller 8 and the driven crushing roller 11 can rotate relative to each other and achieve a speed difference. This speeds up the crushing effect and enhances the shearing, kneading and tearing action between the fibers of the wood used for papermaking by the main crushing roller 8 and the driven crushing roller 11.

[0039] After the wood is crushed, the wood chips and ash fall onto the conveyor plate 17 along the inclined surface in the middle of the feeder 2. At this time, the continuous rotation of the drive shaft 4 will pull the corrugated pipe 21 to rotate in the same direction. The clamping roller 20 fixed by the U-shaped tube 19 will swing left and right repeatedly along the wave groove pattern of the corrugated pipe 21 when the corrugated pipe 21 rotates. At the same time, the conveyor plate 17 will be pulled left and right repeatedly through the U-shaped tube 19. The front and rear sides of the conveyor plate 17 are connected by the L-shaped baffle 22, which transmits the swing of the conveyor plate 17 to the spring 24 and the elastic cloth 23. This causes the spring 24 and the elastic cloth 23 to repeatedly fold and unfold, further increasing the inertia of the swing of the conveyor plate 17. Under the inertia of the swing of the conveyor plate 17, the crushed wood chips and ash will move to the right along the surface of the conveyor plate 17 and be screened when passing through the filter screen 18. This separates the wood ash and wood chips, prevents the feed port from being blocked, and improves the paper quality.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
