Calendering equipment for stone paper production and processing

Abstract

The invention discloses calendering equipment for stone paper production and processing, and relates to the technical field of calendering equipment. In the calendaring process, pressing rollers for calendaring are generally vertically arranged, so that in the calendaring process, due to the fact that a feeding position of a calendaring gap is accumulated in the calendaring process, materials are downwards pulled under the action of gravity, the calendaring position of the materials is broken, and calendaring is affected. Through cooperation of the rotating roller and the heating roller, in the calendaring process, the rotating roller is located on the inclined lower portion of the side, close to the feeding mechanism, of the heating roller, so that materials which do not enter the gap in the calendaring process are supported by the rotating roller, certain supporting force is provided for materials at the feeding position of the gap, and it is avoided that in the calendaring process, the materials cannot enter the gap. Due to the fact that materials are stacked at a feeding port of a calendering gap, the materials are pulled downwards under the action of gravity, the calendering position of the materials is broken, and calendering is affected.

Description

Technical Field

[0001] The present invention relates to the technical field of calendering equipment, and particularly to a calendering equipment for the production and processing of stone paper. Background Art

[0002] Stone paper is a new type of environmentally friendly paper. Its main components are calcium carbonate and a small amount of additives, and it is processed through a special process. The production process of stone paper does not require felling trees and does not involve acid-base chemical treatment in the traditional papermaking process, greatly reducing environmental pollution. At the same time, it is degradable in the natural environment and will not cause long-term white pollution like ordinary plastics. The calendering equipment for the production and processing of stone paper is a key equipment for processing stone paper raw materials into sheet products with a certain thickness and surface quality. The working principle of the stone paper calendering equipment is similar to that of plastic calendering equipment, usually consisting of multiple heated rollers. After preheating, mixing and other preliminary treatments, the raw materials are fed between the rollers of the calender. The rollers rotate at a certain speed and pressure to extrude and extend the raw materials, making them into thin sheets with uniform thickness;

[0003] During the calendering process, the calendering rollers are usually arranged vertically. As a result, during the calendering process, due to the accumulation of materials at the feeding position of the calendering gap, the materials are pulled downward under the action of gravity, resulting in fractures at the calendering position of the materials and affecting calendering. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions:

[0005] A calendering equipment for the production and processing of stone paper, comprising:

[0006] A frame body, at the central position of the top of the frame body, a support plate is installed. The support plates are symmetrically installed along the axis center position of the frame body, and a heating roller is installed between the support plates;

[0007] A feeding mechanism, which is used for pre-pressing the materials. The feeding mechanism is installed on one side of the top of the frame body;

[0008] A discharging mechanism, which is used to provide support for the materials when the materials are discharged. The discharging mechanism is installed on the other side of the top of the frame body;

[0009] A rectangular groove is formed at the top of the outer side of the support plate, and a motor is fixedly installed at the bottom of the outer side of the support plate. A transmission shaft is rotatably installed between the support plates. The output end of the motor is fixedly connected to one end of the transmission shaft through a coupling. A roller is fixedly installed at the central position of the outer side of the transmission shaft. The roller is located obliquely below the heating roller on the side close to the feeding mechanism. By cooperating the roller with the heating roller, during the calendering process, since the roller is located obliquely below the heating roller on the side close to the feeding mechanism, the materials that have not entered the gap during the calendering process are supported by the roller, providing a certain supporting force to the materials at the gap feeding position, avoiding that during the calendering process, due to the accumulation of materials at the calendering gap feeding port, the materials are pulled downward under the action of gravity, resulting in the fracture of the calendering position of the materials and affecting the progress of calendering. Side retaining rings are fixedly installed at both ends of the outer side of the roller. Through the limitation of the side retaining rings, both ends of the gap between the heating roller and the roller are blocked. During the rotational calendering process, the materials in the gap are restricted, avoiding that during the calendering process, both ends of the calendering gap are not blocked, resulting in the continuous overflow of materials at both ends during the calendering process. The opposite surfaces of the side retaining rings are in contact with both ends of the heating roller. Both ends of the heating roller are slidably adapted to the rectangular grooves of the support plate.

[0010] Preferably, screw hole plates are fixedly installed on the outer sides of the support plates. The inner walls of the screw hole plates are threadedly connected with screw studs. A hexagonal head is fixedly installed at the top end of the screw stud, and a rotating column is fixedly installed at the bottom end of the screw stud. The heating roller includes a connecting column, and end sleeves are fixedly installed at both ends of the connecting column. The outer sides of the end sleeves are slidably adapted to the rectangular grooves of the support plates, and through holes are formed at the tops of the end sleeves. The bottom end of the rotating column is rotatably adapted to the through holes of the end sleeves.

[0011] Preferably, end caps are fixedly installed at both ends of the outer side of the connecting column. Annular grooves are evenly formed on the outer side of the end caps, and rotating rings are rotatably installed at the annular grooves of the end caps. A rotating cylinder is fixedly installed on the outer side of the rotating ring. The thickness of the center position of the rotating cylinder is lower than that of both sides. A conduit is fixedly installed on the outer side of the end cap. A hollowed-out cover is fixedly installed at one end of the end cap away from the end sleeve. One end of the conduit close to the end cap penetrates the end cap and extends into the interior of the hollowed-out cover. Filter holes are formed on the opposite surfaces of the hollowed-out cover. The outer side of the hollowed-out cover is in fit with the inner wall of the rotating cylinder, and a sponge filter disc is clamped on the inner wall of the hollowed-out cover. An inner cushion cylinder is fixedly installed at the center position of the outer side of the connecting column. Through the change of the outer diameter of the inner cushion cylinder and the change of the inner wall thickness of the rotating cylinder, the heat at the center position of the rotating cylinder is conducted to the material faster. At the same time, due to the change of the outer diameter of the inner cushion cylinder, the entering heat-conducting oil is guided by the inner cushion cylinder after passing through the filtration of the hollowed-out cover and the sponge filter disc. By using the gradually decreasing gap, the flow rate of the heat-conducting oil is accelerated, so that it quickly approaches the center position, ensuring the heating effect on the material during the calendering operation and avoiding the influence of low temperature on the calendering effect. And the outer diameter of the inner cushion cylinder gradually decreases from the center position to both ends.

[0012] Preferably, the feeding mechanism includes a support frame. Rotating rollers are rotatably installed on both sides of the inner wall of the support frame. Column grooves are symmetrically formed on both sides of the support frame. A fixed roller is rotatably installed on the inner wall of the support frame. The fixed roller is located between the rotating rollers and is symmetrically installed along the axis center position of the support frame. Sliding rollers are slidably installed at the column grooves of the support frame. Through the pre-pressure of the sliding rollers and the fixed roller, the material is pre-rolled before calendering, which is convenient for the material to enter the calendering gap and prevent material jamming. At the same time, during the pre-pressure process, due to the change of the outer diameter of the sliding roller, the gap at the center position between the sliding roller and the fixed roller is increased, so that the center position of the pre-rolled material is thicker, avoiding a large amount of overflow of the material at both ends during the calendering process due to the larger thickness of the material on both sides. The sliding roller is located obliquely above the side of the fixed roller away from the rotating roller, and end blocks are rotatably installed at both ends of the sliding roller. Rod holes are symmetrically formed at the tops of the end blocks, and sliding rods are slidably installed at the rod holes of the end blocks. A top plate is fixedly installed at the top ends of the sliding rods. A spring is fixedly installed between the top plate and the end block. The outer diameter of the sliding roller gradually increases from the center position to both ends.

[0013] Preferably, the discharging mechanism includes side plates symmetrically installed at the top of the frame along the axial center position of the frame, and a fixed rod is fixedly installed between the side plates. A top inner cylinder is rotatably installed at the center position outside the fixed rod. By cooperating the top inner cylinder with the side supporting rollers, when discharging the rolled material, through the protrusion at the center position of the top inner cylinder, the center position of the bottom of the material is supported, and in cooperation with the side supporting rollers to support the two side edge positions of the material, to prevent the rolled material from breaking during the discharging process due to the thin thickness of the rolled material and the lack of supporting force during the feeding process. The outer diameter of the top inner cylinder gradually decreases from the center position to both ends. Connecting blocks are fixedly installed on the opposite surfaces of the side plates, and side supporting rollers are rotatably installed at the ends of the connecting blocks away from the side plates. The ends of the side supporting rollers away from the side plates are inclined downward.

[0014] The present invention provides a calendering device for the production and processing of stone paper. It has the following beneficial effects:

[0015] First, in the calendering device for the production and processing of stone paper, through the cooperation of the rotating roller and the heating roller, during the calendering process, by using the rotating roller located obliquely below the heating roller on the side close to the feeding mechanism, the material that has not entered the gap during the calendering process is supported by the rotating roller, providing a certain supporting force for the material at the gap feeding position, and preventing the material from breaking at the calendering position due to the accumulation of material at the calendering gap feeding port and the downward pulling of the material under the action of gravity during the calendering process, which affects the progress of calendering.

[0016] Second, in the calendering device for the production and processing of stone paper, through the restriction of the side retaining rings, both ends of the gap between the heating roller and the rotating roller are blocked, restricting the material in the gap during the rotational calendering process, and preventing the material from continuously overflowing at both ends during the calendering process due to the lack of blockage at both ends of the calendering gap.

[0017] Third, in the calendering device for the production and processing of stone paper, through the change in the outer diameter of the inner cushion cylinder and the change in the inner wall thickness of the rotating cylinder, the heat at the center position of the rotating cylinder is conducted to the material faster. At the same time, the change in the outer diameter of the inner cushion cylinder guides the introduced heat-conducting oil after passing through the hollow cover and the sponge filter disk. By using the gradually decreasing gap, the flow rate of the heat-conducting oil is accelerated, enabling it to quickly approach the center position, ensuring the heating effect on the material during the calendering operation, and preventing the calendering effect from being affected due to low temperature.

[0018] IV. The calendering equipment for the production and processing of stone paper pre-presses the material through the sliding roller and the fixed roller, so that the material is pre-rolled before calendering, which facilitates the material to enter the calendering gap and prevents material jamming. At the same time, during the pre-pressing process, the gap at the center position between the sliding roller and the fixed roller is increased by changing the outer diameter of the sliding roller, making the center position of the pre-pressed material thicker, and avoiding a large amount of overflow at both ends of the material during the calendering process due to the greater thickness of the material on both sides. The sliding roller is located obliquely above the side of the fixed roller away from the supporting roller, and end blocks are rotatably installed at both ends of the sliding roller.

[0019] V. The calendering equipment for the production and processing of stone paper cooperates with the inner top cylinder and the side supporting roller. When exporting the calendered material, the protrusion at the center position of the inner top cylinder supports the center position of the bottom of the material, and cooperates with the side supporting roller to support the edge positions on both sides of the material, avoiding breakage of the calendered material during the export process due to the thin thickness of the calendered material and the lack of supporting force during the feeding process.

Specific implementation manner

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] The first embodiment is as Figures 1 to 4 shown. The present invention provides a technical solution:

[0033] A calendering device for the production and processing of stone paper, comprising:

[0034] A frame 1, at the central position of the top of the frame 1, a support plate 5 is installed. The support plates 5 are symmetrically installed along the central axis of the frame 1, and a heating roller 2 is installed between the support plates 5;

[0035] A feeding mechanism 3, which is used to pre-press the material. The feeding mechanism 3 is installed on one side of the top of the frame 1;

[0036] A discharging mechanism 4, which is used to provide support for the material when the material is exported. The discharging mechanism 4 is installed on the other side of the top of the frame 1;

[0037] A rectangular groove is formed at the top of the outer side of the support plate 5, and a motor 7 is fixedly installed at the bottom of the outer side of the support plate 5. A transmission shaft 9 is rotatably installed between the support plates 5. The output end of the motor 7 is fixedly connected to one end of the transmission shaft 9 through a coupling. A roller 6 is fixedly installed at the central position of the outer side of the transmission shaft 9. The roller 6 is located obliquely below the heating roller 2 on the side close to the feeding mechanism 3. During the calendering process, the motor 7 drives the transmission shaft 9, so that the transmission shaft 9 drives the roller 6 to rotate, and the roller 6 drives the material to move, so that the material passes through the gap between the roller 6 and the heating roller 2, and the material is calendered during the heating process. At the same time, during the calendering process, the roller 6 is located obliquely below the heating roller 2 on the side close to the feeding mechanism 3, so that the roller 6 provides support for the material that has not entered the gap. At the same time, the side retaining rings 8 at both ends of the roller 6 limit the material in the gap. Side retaining rings 8 are fixedly installed at both ends of the outer side of the roller 6. The opposite surfaces of the side retaining rings 8 are in contact with both ends of the heating roller 2. Both ends of the heating roller 2 are slidably matched with the rectangular grooves of the support plate 5.

[0038] Screw hole plates 12 are fixedly installed on the outer sides of the support plates 5. A stud 11 is threadedly connected to the inner wall of the screw hole plate 12. A hexagonal head 13 is fixedly installed at the top end of the stud 11, and a rotating column 10 is fixedly installed at the bottom end of the stud 11. The heating roller 2 includes a connecting column 25. According to the required calendering thickness, the worker uses a wrench to drive the stud 11 to rotate through the hexagonal head 13. Utilizing the threaded connection between the stud 11 and the screw hole plate 12, the stud 11 drives the rotating column 10 as required, so that the heating roller 2 slides up and down in the rectangular groove of the support plate 5 to adjust the gap size between the heating roller 2 and the roller 6. Both ends of the connecting column 25 are fixedly installed with end sleeves 21. The outer sides of the end sleeves 21 are slidably matched with the rectangular grooves of the support plate 5, and through holes are formed at the tops of the end sleeves 21. The bottom end of the rotating column 10 is rotatably matched with the through hole of the end sleeve 21.

[0039] Second Embodiment. On the basis of the First Embodiment, please refer to Figures 5 to 7As shown in the figure, end caps 22 are fixedly installed at both ends outside the connecting column 25. Annular grooves are evenly formed on the outer sides of the end caps 22, and rotating rings 28 are rotatably installed at the annular groove positions of the end caps 22. A rotating cylinder 24 is fixedly installed on the outer side of the rotating ring 28. The thickness at the central position of the rotating cylinder 24 is lower than that of both sides. The hot oil pipeline is connected to the conduit 23. Both ends of the connecting column 25 are rotatably connected to the rotating column 10 through end sleeves 21. At the same time, the end sleeves 21 are adapted to the rectangular grooves of the support plate 5 to limit the rotation of the connecting column 25. At the same time, during calendering, the frictional force between the rotating cylinder 24 and the material causes the material to drive the rotating cylinder 24 to rotate during movement. A conduit 23 is fixedly installed on the outer side of the end cap 22. Hollow covers 27 are fixedly installed at the ends of the end caps 22 away from the end sleeves 21. One end of the conduit 23 close to the end cap 22 penetrates through the end cap 22 and extends into the interior of the hollow cover 27. Filter holes are formed on the opposite surfaces of the hollow cover 27. The outer side of the hollow cover 27 is in contact with the inner wall of the rotating cylinder 24. During rotation, the introduced high-temperature hot oil first enters the hollow cover 27 inside the end cap 22. Subsequently, the hot oil enters the gap between the inner cushion cylinder 26 and the rotating cylinder 24 through the filtration of the hollow cover 27 and the sponge filter disc 29. Through the change in the outer diameter of the inner cushion cylinder 26, the heat-conducting oil quickly enters the central position inside the rotating cylinder 24, and the heat is transferred to the material through the rotating cylinder 24 to perform heat treatment and calendering on the material. A sponge filter disc 29 is clamped on the inner wall of the hollow cover 27. An inner cushion cylinder 26 is fixedly installed at the central position outside the connecting column 25, and the outer diameter of the inner cushion cylinder 26 gradually decreases from the central position to both ends.

[0040] The third embodiment is based on the first and second embodiments. Please refer to Figures 8 to 10As shown in the figure, the feeding mechanism 3 includes a support frame 31. On both sides of the inner wall of the support frame 31, there are rotatably installed carrying rollers 35. And on both sides of the support frame 31, there are symmetrically arranged column grooves. The material after heating, mixing and extrusion is introduced from the top of the carrying roller 35 on the side far from the rotating roller 6. The material is supported by the carrying roller 35, and then the material enters the gap between the fixed roller 32 and the sliding roller 36. At the same time, during the process of the rotating roller 6 rotating to drive the material to move, the elastic force of the spring 38 pulls the sliding roller 36 close to the fixed roller 32, so that the passing material is squeezed by the fixed roller 32 and the sliding roller 36, and the introduced material is pre-pressed before calendering. The inner wall of the support frame 31 is rotatably installed with a fixed roller 32. The fixed roller 32 is located between the carrying rollers 35 and is symmetrically installed along the axis center position of the support frame 31. There are sliding rollers 36 slidably installed at the column grooves of the support frame 31. The sliding rollers 36 are located obliquely above the side of the fixed roller 32 far from the carrying roller 35. And at both ends of the sliding roller 36, there are rotatably installed end blocks 33. On the top of the end blocks 33, there are symmetrically arranged rod holes. And at the rod holes of the end blocks 33, there are slidably installed sliding rods 37. During the pre-pressing process, due to the change in the outer diameter of the sliding roller 36, the thickness of the center position of the pre-pressed material is greater than that of both sides, and at the same time, the position of the material is positioned so that the center position of the material is maintained when it is introduced into the gap between the rotating roller 6 and the heating roller 2. The top end of the sliding rod 37 is fixedly installed with a top plate 34. A spring 38 is fixedly installed between the top plate 34 and the end block 33. The outer diameter of the sliding roller 36 gradually increases from the center position to both ends.

[0041] The discharging mechanism 4 includes side plates 41. The side plates 41 are symmetrically installed on the top of the frame body 1 along the axis center position of the frame body 1. And between the side plates 41, there is fixedly installed a fixed rod 42. At the center position of the outside of the fixed rod 42, there is rotatably installed an inner top cylinder 43. The outer diameter of the inner top cylinder 43 gradually decreases from the center position to both ends. On the opposite surfaces of the side plates 41, there are fixedly installed connecting blocks 45. The material after calendering by the heating roller 2 and the rotating roller 6 enters the top of the inner top cylinder 43 and is led out of the calendering device by the traction equipment. During the leading-out process, through the cooperation of the inner top cylinder 43 and the side supporting rollers 44, using the protrusion at the center position of the inner top cylinder 43, the inner top cylinder 43 supports the center position of the material. At the same time, for the two sides of the thinned material, the side supporting rollers 44 support the bottom of the two sides of the material. The end of the connecting block 45 far from the side plate 41 is rotatably installed with a side supporting roller 44. The end of the side supporting roller 44 far from the side plate 41 is inclined downward.

[0042] During use, the mixed and extruded material is introduced by the feeding mechanism 3. The feeding mechanism 3 preliminarily thins the passing material, and then guides the material into the gap between the heating roller 2 and the rotating roller 6. The thinning thickness of the material during calendering is controlled by adjusting the gap between the heating roller 2 and the rotating roller 6, so that the passing material is thinned while being heated. Subsequently, the thinned material enters the discharging mechanism 4, and the discharging mechanism 4 supports and restricts the calendered material, so that the material is exported from the calendering equipment and enters the next process.

[0043] During use, according to the required calendering thickness, the worker can use a wrench to drive the stud 11 to rotate through the hexagonal head 13. Utilizing the threaded connection between the stud 11 and the threaded hole plate 12, the stud 11 drives the rotating column 10 as needed, so that the heating roller 2 slides up and down in the rectangular groove of the support plate 5 to adjust the gap size between the heating roller 2 and the rotating roller 6. At the same time, during the calendering process, the drive shaft 9 is driven by the motor 7, so that the drive shaft 9 drives the rotating roller 6 to rotate, the rotating roller 6 drives the material to move, the material passes through the gap between the rotating roller 6 and the heating roller 2, and the material is calendered while being heated. At the same time, during the calendering process, the rotating roller 6 is located diagonally below the heating roller 2 on the side close to the feeding mechanism 3, so that the rotating roller 6 provides support for the material that has not entered the gap. At the same time, the side retaining rings 8 at both ends of the rotating roller 6 restrict the material in the gap.

[0044] In the feeding mechanism 3, the heated and mixed extruded material is introduced from the top of the supporting roller 35 on the side far from the rotating roller 6. The supporting roller 35 supports the material, and then the material enters the gap between the fixed roller 32 and the sliding roller 36. At the same time, during the process of the rotating roller 6 driving the material to move, the elastic force of the spring 38 pulls the sliding roller 36 close to the fixed roller 32, so that the passing material is squeezed by the fixed roller 32 and the sliding roller 36, and the introduced material is pre-pressed before calendering. At the same time, during the pre-pressing process, due to the change in the outer diameter of the sliding roller 36, the thickness of the center position of the pre-pressed material is greater than that of both sides, and the position of the material is positioned so that the material maintains the center position when it is introduced into the gap between the rotating roller 6 and the heating roller 2.

[0045] In the heating roller 2, a hot oil pipeline is connected to the conduit 23. Both ends of the connecting column 25 are rotatably connected to the rotating column 10 through end sleeves 21. At the same time, the end sleeves 21 are adapted to the rectangular grooves of the support plate 5 to limit the rotation of the connecting column 25. Meanwhile, during calendering, the frictional force between the rotating cylinder 24 and the material causes the material to drive the rotating cylinder 24 to rotate during movement. During rotation, the introduced high-temperature hot oil first enters the hollow cover 27 inside the end cover 22, and then the hot oil enters the gap between the inner cushion cylinder 26 and the rotating cylinder 24 through the filtration of the hollow cover 27 and the sponge filter disc 29. Through the change in the outer diameter of the inner cushion cylinder 26, the heat-conducting oil quickly enters the central position inside the rotating cylinder 24, and the heat is transferred to the material through the rotating cylinder 24 to perform heat calendering treatment on the material.

[0046] In the discharging mechanism 4, the material after being calendered by the heating roller 2 and the rotating roller 6 enters the top of the inner top cylinder 43 and is led out of the calendering device by the traction device. During the leading-out process, through the cooperation of the inner top cylinder 43 and the side support rollers 44, using the protrusion at the central position of the inner top cylinder 43, the inner top cylinder 43 supports the central position of the material. At the same time, on both sides of the thinned material, the side support rollers 44 support the bottom of both sides of the material.
