Description

Technical Field

[0001] This invention relates to the field of paper production and processing equipment technology, specifically a composite filler treatment device for decorative base paper. Background Technology

[0002] In the paper production process, the use of composite fillers in decorative base paper plays a crucial role in improving the paper's physical and printability. Composite fillers not only enhance paper opacity and smoothness but also reduce production costs, as they are generally more economical than fiber raw materials. However, the efficient processing of composite fillers has always been a challenge in the industry. Filler processing involves multiple steps, including crushing, grinding, and uniform mixing with pulp, and the efficiency of these steps directly impacts the quality of the paper product.

[0003] Traditional methods for processing composite fillers have several problems. First, the inefficiency of crushing and grinding results in uneven filler particle size, which affects their distribution in the paper and the final paper quality. Second, the mixing of fillers and pulp in traditional methods is often insufficient, leading to unstable paper properties. Furthermore, existing processing equipment is often complex to maintain, difficult to clean and replace worn parts, increasing downtime and maintenance costs. Summary of the Invention

[0004] To address the shortcomings of the existing technology, the present invention aims to provide a composite filler processing device for decorative base paper. This device, through an integrated crushing cylinder and a multi-functional grinding mechanism, effectively crushes and grinds the composite filler.

[0007] The aforementioned crushing and grinding mechanism includes the following components:

[0008] The crushing cylinder body is closed at both ends. The upper part of the crushing cylinder body is provided with a feed inlet, and the lower part of the crushing cylinder body is provided with a discharge outlet. A filter plate is provided on the discharge outlet. The discharge outlet corresponds to the position of the feed inlet, and the feed inlet corresponds to the position of the feed pipe.

[0009] The crushing and stirring blade mechanism is rotatably disposed inside the crushing body;

[0010] The upper crushing blade is located near the inner wall of the crushing and stirring blade mechanism. The upper crushing blade has a cutting edge with an arc shape. The upper crushing blade is detachably mounted on the crushing and stirring blade machine by fasteners.

[0011] The grinding and pulverizing grid is located at the discharge port at the bottom of the grinding cylinder body. The grinding and pulverizing grid has several rotating and evenly arranged grinding and pulverizing shafts. The two ends of the grinding and pulverizing shafts are provided with return springs, and the rotating positions of the ends of the grinding and pulverizing shafts are provided with stops.

[0012] The lower crushing blade is set on the axial surface of the crushing and grinding shaft, and when the upper crushing blade is at the bottom, a crushing gap is formed between the lower crushing blade and the upper crushing blade.

[0013] The first motor is fixedly mounted on the upper part of the fixed base and located on the outside of the crushing box. The first motor is connected to the crushing and stirring blade mechanism for transmission.

[0014] In a preferred embodiment, the two ends of the crushing cylinder body are closed, and the crushing cylinder body includes an upper body and a lower body, which are fixedly connected by fasteners.

[0015] In the preferred embodiment, the crushing and stirring blade mechanism includes a rotating shaft rotatably disposed inside the crushing cylinder body, a fixed bracket fixed on the rotating shaft, the rotating shaft being drivenly connected to a first motor, and the fixed bracket being detachably connected to the upper crushing blade.

[0016] In a preferred embodiment, the grinding grid includes a grid frame that is slidably mounted on the lower side of the inside of the grinding cylinder body via a telescopic component, and the grinding shaft is rotatably and evenly mounted on the grid frame.

[0017] In a preferred embodiment, the lower crushing blade is a straight blade, and the lower crushing blade is inclinedly mounted on the crushing and grinding shaft.

[0018] In a preferred embodiment, an elongated groove is provided on the upper crushing blade at the connection point with the fixed bracket.

[0019] In a preferred embodiment, the feeding and conveying mechanism includes a conveying cylinder, an auger rotatably mounted inside the conveying cylinder, spray pipes on both sides of the outer side of the conveying cylinder, spray nozzles evenly arranged on the spray pipes, the inner end of each spray nozzle extending into the interior of the conveying cylinder and located between the blades of the auger, a feed hopper fixedly mounted on the upper side of the end of the conveying cylinder away from the feed pipes, and a second motor mounted on the outer side of the conveying cylinder, the second motor being drivenly connected to the auger.

[0020] In a preferred embodiment, a cover plate is provided on one end of the crushing box, and the cover plate is connected to the crushing box by a locking fastener.

[0021] The beneficial effects of this invention are:

[0022] Improved crushing efficiency: The combination of the crushing cylinder body, the crushing and stirring blade mechanism, the upper crushing blade, the crushing and grinding grid and the lower crushing blade enables effective crushing of composite filler raw materials, thereby improving crushing efficiency.

[0023] Optimize the production process: The spray pipe sprays a solution containing a retention aid onto the composite filler raw material through the spray head. The retention aid can increase the retention rate of the pulp when it is fed into the paper, effectively maintaining the retention of the composite filler in the paper, thereby optimizing the entire production process.

[0024] Preventing high-temperature denaturation: The liquid containing retention aid can play a cooling role in the next step of crushing and grinding the composite filler raw materials, preventing the composite filler and retention aid from denaturing when exposed to high temperatures.

[0025] Enhanced crushing and grinding effect: The spray nozzle extends between the blades of the conveying auger, spraying liquid from inside the composite packing material. The spray nozzle also has a certain stirring effect on the continuously moving composite packing material, which can better mix the composite packing material with the liquid, and at the same time enhance the crushing and grinding effect.

[0026] Easy discharge: In addition to crushing and cutting the composite filler raw materials, the arc-shaped blade will also exert a certain compressive force on the composite filler on the upper part of the crushing and grinding shaft. The compressive force can crush the composite filler and continuously squeeze the smaller composite filler particles into the gap between the crushing and grinding shaft, making it easier to discharge.

[0027] To prevent clogging: The rotating and vibrating grinding shaft facilitates material discharge, and the rotating lower grinding blade exerts a certain compressive force on the composite filler between the grinding shaft and the material, thus accelerating the discharge of the crushed composite filler. The rotating grinding shaft can also grind the composite filler particles between the grinding shaft and the lower body. In summary, the present invention has a better cutting effect, facilitates material discharge, and is less prone to clogging during discharge. Attached Figure Description

[0037] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0038] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] like Figure 1 and 2 As shown, a composite filler treatment device for decorative base paper includes a fixed base 1, a crushing box 2, a crushing and grinding mechanism 3, a feed pipe 4, and a feeding conveying mechanism 5. The crushing box 2 is fixedly installed on the upper side of the fixed base 1, and a discharge port 21 is provided on the lower side of the crushing box 2. The crushing and grinding mechanism 3 is located inside the crushing box 2, the feed pipe 4 is located on the upper side of the crushing box 2, and the feeding conveying mechanism 5 is located on the upper side of one end of the feed pipe 4. A cover plate 22 is provided on one end of the crushing box 2, and the cover plate 22 is connected to the crushing box 2 by a locking fastener 23, which facilitates the daily maintenance of the crushing and grinding mechanism 3.

[0040] like Figure 2 , 3 As shown in Figures 4, 5, and 6, the crushing and grinding mechanism includes the following components:

[0041] The crushing cylinder body 31 is closed at both ends. The upper part of the crushing cylinder body 31 is provided with a feed inlet 311 and the lower part of the crushing cylinder body 31 is provided with a discharge outlet 312. A filter plate 315 is provided on the discharge outlet 312. The discharge outlet 312 corresponds to the position of the feed inlet 21 and the feed inlet 311 corresponds to the position of the feed pipe 4.

[0042] The crushing and stirring blade mechanism 32 is rotatably disposed inside the crushing body 31.

[0043] The upper crushing blade 33 is located on the inner wall of the crushing and stirring blade mechanism 32 near the crushing cylinder body 31. The upper crushing blade 33 has a blade 331 with an arc shape. The upper crushing blade 33 is detachably mounted on the crushing and stirring blade mechanism 32 by fasteners.

[0044] The grinding and crushing grid 34 is located at the discharge port 312 at the lower part of the grinding cylinder body 31. The grinding and crushing grid 34 has several rotating and evenly arranged grinding and crushing shafts 341. The two ends of the grinding and crushing shafts 341 are provided with return springs 342. The rotating position of the end of the grinding and crushing shafts 341 is provided with a stop block 344. After the grinding and crushing shafts 341 rotates a certain angle, the stop block 344 will be blocked by the grid frame 343, so that the grinding and crushing shafts 341 can only rotate a certain angle. The return springs 342 can drive the rotation of the grinding and crushing shafts 341 to return to the original position.

[0045] The lower crushing blade 35 is disposed on the axial surface of the crushing and grinding shaft 341, and when the upper crushing blade 33 is at the bottom, a crushing gap is formed between the lower crushing blade 35 and the upper crushing blade 33.

[0046] The first motor 36 is fixedly mounted on the upper part of the fixed base 1 and located on the outside of the crushing box 2. The first motor 36 is connected to the crushing and stirring blade mechanism 32 for transmission.

[0047] The two ends of the crushing cylinder body 31 are closed. The crushing cylinder body 31 includes an upper body 313 and a lower body 314, which are fixedly connected by fasteners.

[0048] The crushing and stirring blade mechanism 32 includes a rotating shaft 321 rotatably disposed inside the crushing cylinder body 31, a fixed bracket 322 fixed on the rotating shaft 321, the rotating shaft 321 being connected to the first motor 36 for transmission, and the fixed bracket 322 being detachably connected to the upper crushing blade 33.

[0049] like Figure 4 and 8 As shown, the grinding and pulverizing grid 4 includes a grid frame 343 that is slidably disposed on the lower side inside the grinding cylinder body 31 via a telescopic assembly 345. The grinding and pulverizing shaft 341 is rotatably and evenly disposed on the grid frame 343. The telescopic assembly 345 includes a telescopic sleeve, a telescopic rod, and a compression spring. One end of the telescopic rod is slidably disposed inside the telescopic sleeve, and the compression spring is sleeved on the telescopic rod and located between the telescopic sleeve and the telescopic rod.

[0050] The lower crushing blade 35 is a straight blade, and the lower crushing blade 35 is inclinedly mounted on the crushing and grinding circular shaft 341.

[0051] An elongated groove 332 is provided on the upper crushing blade 33 at the connection point with the fixed bracket 322, which can adjust the gap between the upper crushing blade 33 and the lower crushing blade 35, thereby better crushing composite filler raw material particles of different sizes.

[0052] like Figure 1 , 2 As shown in Figure 7, the feeding and conveying mechanism 5 includes a conveying cylinder 51, a conveying auger 52 is rotatably arranged inside the conveying cylinder 51, spray pipes 53 are arranged on both sides of the outer side of the conveying cylinder 51, spray heads 56 are evenly arranged on the spray pipes 53, the inner end of the spray head 56 extends into the interior of the conveying cylinder 51 and is located between the blades of the conveying auger 52, a feeding hopper 54 is fixedly arranged on the upper side of the end of the conveying cylinder 51 away from the feeding pipe 4, and a second motor 55 is arranged on the outer side of the conveying cylinder 51, the second motor 55 is connected to the conveying auger 52 for transmission.

[0053] like Figure 1-8As shown, the working process of this invention is as follows:

[0054] First, the first motor 36 and the second motor 55 are started, driving the crushing and grinding mechanism 3 and the feeding and conveying mechanism 5 to add the composite filler raw material from the feed hopper 54 into the conveying cylinder 51. Under the action of the conveying auger 52, the composite filler raw material can be continuously conveyed forward. During the conveying process, the spray pipe 53 sprays liquid onto the composite filler raw material through the spray head 56. This liquid is a solution with added retention aids. The retention aids are selected from polyacrylamide and starch-modified products. These retention aids are water-soluble and can easily combine with the filler. By increasing the retention rate of the pulp when it is fed onto the wire, the retention aids effectively maintain the retention of the composite filler in the paper, thereby optimizing the entire production process. Moreover, the liquid containing the retention aids can play a cooling role in the next step of crushing and grinding the composite filler raw material, preventing the composite filler and retention aid from denaturing when exposed to high temperatures, and also increasing the crushing and grinding effect. The spray nozzle 56 extends between the blades of the conveying auger 52, spraying liquid from inside the composite packing material. The spray nozzle 56 also provides a certain degree of agitation to the continuously moving composite packing material, ensuring better and more uniform mixing between the material and the liquid. The conveying auger 52 transports the composite packing material to the feed pipe 4, and from there it passes through the crushing box 2 into the crushing and grinding mechanism 3 for crushing and grinding. The crushed and ground composite packing material is then discharged from the discharge port 21 to proceed to the next process.

[0055] In use, the composite filler material enters the interior of the crushing cylinder body 31 through the feed inlet 311. The crushing and stirring blade mechanism 32 rotates counterclockwise under the power of the external first motor 36, thereby driving the upper crushing blade 33 to rotate. The composite filler material entering from the feed inlet 311 is first beaten by the upper crushing blade 33. Some larger particles of composite filler will break and fall into the upper part of the crushing and grinding grid 34. Then, the blade 331 of the upper crushing blade 33 will interact with the crushing and grinding shaft 341 and the lower crushing blade 35. The composite filler that falls into the upper part of the grinding shaft 341 is further crushed. The crushed composite filler will enter the lower side of the shaft 341 through the gap in the middle of the shaft 341. Since the shaft 341 can move up and down and rotate at the same time as the upper crushing blade 33 and the lower crushing blade 35, the shaft 341 can grind the composite filler on the lower side. When the crushed particles are relatively small, the composite filler falls down from the discharge port 312 after being filtered by the filter plate 315 and is discharged from the discharge port 21.

[0056] like Figure 2As shown, the arc-shaped blade 331 in this embodiment, in conjunction with the grinding and crushing shaft 341 and the lower grinding blade 35, has at least the following cutting methods: a grinding engagement occurs between the blade 331 and the grinding and crushing shaft 341; a grinding engagement is formed between the blade 331 and the lower grinding blade 35; when the grinding and crushing shaft 341 is rotated under pressure, it drives the grinding blade 35 to rotate counterclockwise, and a grinding engagement is formed between the grinding blade 35 and the adjacent grinding and crushing shaft 341; since the composite filler is ground and crushed after the addition of liquid, under normal circumstances, after grinding and crushing, the composite filler and liquid mix into a viscous mixture, which easily adheres to the gaps between the grinding and crushing shafts 341 and the filter plate 315, making it difficult to feed the material. In addition to its function of grinding and cutting the composite filler material, the arc-shaped blade 331's curved back surface will contact the grinding and crushing shaft 341. The upper composite filler generates a certain compressive force, which can crush the composite filler and continuously compress the smaller composite filler particles after crushing into the gaps between the crushing and grinding shafts 341, making it easier to discharge the material. Moreover, the gaps formed between the crushing and grinding shafts 341 are inherently easier to discharge than the gaps formed between the square bars. In addition, the lower crushing blade 35 in this embodiment is compressed, which drives the crushing and grinding shaft 341 to rotate. The rotation and up-and-down vibration of the crushing and grinding shaft 341 also facilitates the discharge of the material. Furthermore, the rotating lower crushing blade 35 also exerts a certain compressive force on the composite filler in the gaps between the crushing and grinding shafts 341, thus accelerating the discharge of the crushed composite filler. The rotating crushing and grinding shaft 341 can also grind the composite filler particles between the crushing and grinding shaft 341 and the lower body 314. In summary, this embodiment has a better cutting effect, facilitates material discharge, and is less prone to clogging during discharge.

[0057] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
