Description

Technical Field

[0001] The present application relates to the technical field of extruded board production, and in particular to an extruded board production line and processing technology. Background Art

[0002] Extruded boards are mainly used in building insulation, airport runway insulation and other fields. Extruded boards are often produced using a continuous extrusion foaming process.

[0003] At present, the extruded board production line includes a feeding device, a foaming extrusion device, a shaping device, a conveying device, a shaping device and a slitting device which are arranged in sequence. The feeding device is used to heat, stir, mix and convey new raw materials and old raw materials and other materials to the foaming extrusion device for foaming and expansion extrusion, and then produce an extruded belt of predetermined thickness and width through the shaping device, and the extruded belt is conveyed by the conveying device through the shaping device and the slitting device in sequence. The shaping device trims and peels the extruded board, and the slitting device cuts the extruded belt into extruded boards of predetermined length. Since waste materials are generated when the machine is preheated and are cut off by the slitting device, and waste materials are also obtained after trimming and peeling, in order to facilitate the recycling of waste materials, the current extruded board production line also includes a granulating device for melting, extruding and cutting the collected and stored waste materials into granules to obtain the old raw materials. When collecting and storing waste materials, the waste materials obtained in the process will be collected regularly and then melted and extruded into waste blocks using an extruder, thereby reducing the floor space, and after being stored to a predetermined amount, they are granulated together by the granulating device to form old raw materials.

[0004] However, since the waste is collected into the extruder for extrusion intermittently, some of the waste that stays in the extruder for a long time will be carbonized. The carbonized layer is dispersed in the waste block and granulated together to make old raw materials. On the one hand, the dark color is not conducive to the color adjustment of the extruded board using the old raw materials. On the other hand, it will cause the strength of the extruded board using the old raw materials to decrease, resulting in poor quality of the extruded board produced. Summary of the invention

[0005] In order to improve the problem that the old raw materials contain a carbonized layer, resulting in poor quality of the produced extruded boards, the present application provides an extruded board production line and processing technology.

[0006] On the one hand, the present application provides an extruded board production line adopting the following technical solution:

[0007] An extruded board production line comprises a feeding device, a foaming extrusion device, a shaping device, a conveying device, a shaping device, a slitting device and a granulating device which are arranged in sequence, and also comprises a crushing mechanism for crushing waste blocks into selected materials, a sorting mechanism for separating particles and carbon powder in the selected materials and a conveyor belt for conveying the selected materials to the sorting mechanism, wherein the sorting mechanism is used to separately collect the particles and carbon powder in the selected materials.

[0008] By adopting the above technical scheme, in the process of producing extruded boards, new raw materials, old raw materials and other materials are heated, stirred, mixed and conveyed to the foaming extrusion device for foaming and expansion extrusion through the feeding device, and then an extruded belt with a predetermined thickness and width is produced through the shaping device. The extruded belt is conveyed by the conveying device and sequentially passes through the shaping device and the slitting device. The shaping device trims and peels the extruded board to obtain waste material, and the slitting device cuts the extruded belt into extruded boards of predetermined lengths; the obtained waste material is melted and extruded into waste blocks for storage, and when the stored waste blocks reach a predetermined amount, the waste material is stored in a predetermined amount of waste material. The crushing mechanism crushes the waste blocks into selected materials. Since there is a carbonized layer in the waste blocks and the bonding effect of the carbonized layer with the plastic is weak, the waste blocks will form selected materials containing carbon powder and plastic particles after being crushed. The selected materials are conveyed to the sorting mechanism through a conveyor belt and the plastic particles and carbon powder are collected separately by the sorting mechanism. Finally, the collected plastic particles are made into granular old raw materials through a granulating device, and the old raw materials are mixed with new raw materials and other materials and added to the feeding device, thereby reducing the content of the carbonized layer in the old raw materials and improving the problem of poor quality of the extruded board produced due to the carbonized layer in the old raw materials.

[0009] Optionally, the conveyor belt is inclined, and its end close to the crushing mechanism is lower than its end close to the sorting mechanism. The sorting mechanism includes a recovery box for receiving particles and a sorting box for receiving carbon powder. The sorting box and the recovery box are both opened near the end of the conveyor belt away from the crushing mechanism. The planes where the openings of the sorting box and the recovery box are located are staggered in the vertical direction, and the opening of the recovery box is located on the side of the opening of the sorting box close to the conveyor belt.

[0010] By adopting the above technical scheme, when it is necessary to sort the particles and carbon powder in the sorting material, the sorting material is conveyed along the inclined conveyor belt to the openings above the sorting box and the recycling box. Since the air resistances of the carbon powder and the particles are inconsistent, under the action of gravity, the plastic particles in the sorting material fall at the opening of the recycling box closer to the conveyor belt, and the carbon powder floats at the opening of the sorting box located above the recycling box, thereby collecting the plastic particles and the carbon powder separately. Finally, the plastic particles in the recycling box are made into granular old raw materials through a granulating device, and the old raw materials are mixed with new raw materials and other materials and added to the feeding device, thereby reducing the content of the carbonized layer in the old raw materials, and improving the problem of poor quality of the extruded board produced due to the carbonized layer in the old raw materials.

[0011] Optionally, the sorting mechanism further comprises a control component for directing the carbon powder into the sorting box according to the content of the carbon powder in the sorting material.

[0012] By adopting the above technical scheme, the content of carbonized layer in the waste blocks produced is different due to the different batches of waste materials, so that the content of carbon powder obtained after crushing the waste blocks in the sorting material is different. When the conveyor belt is conveying the sorting material, the control component is used to adaptively guide the carbon powder content at the point where it leaves the conveyor belt, thereby improving the accuracy of carbon powder separation, thereby improving the sorting effect of carbon powder in the sorting material, reducing the content of carbonized layer in the old raw materials, and improving the problem of poor quality of extruded boards produced due to the carbonized layer in the old raw materials.

[0013] Optionally, the control assembly includes an industrial camera for taking a picture of an end of the conveyor belt away from the crushing mechanism, a control module for receiving a signal from the industrial camera, a guide plate rotatably connected to the sorting box, and a first servo motor for driving the guide plate to rotate, the rotation axis of the guide plate is arranged parallel to the width direction of the conveyor belt, one side of the guide plate extends to a side of the sorting box close to the conveyor belt, and the first servo motor is electrically connected to the control module;

[0014] When the brightness of the sorted material photographed by the industrial camera is lower than a threshold, the control module drives the first servo motor to drive the material guide plate to rotate toward the recycling box by a preset angle;

[0015] When the brightness of the sorted material photographed by the industrial camera is higher than a threshold value, the control module drives the first servo motor to drive the material guide plate to rotate a preset angle in a direction away from the recycling box.

[0016] By adopting the above technical solution, when the sorted material is transported by the conveyor belt to the end away from the crushing mechanism, the industrial camera takes a photo of the sorted material on the conveyor belt and transmits the signal to the control module. When the control module recognizes that the brightness of the sorted material in the photo transported by the industrial camera is lower than the predetermined threshold value, it means that the black toner content in the sorted material is relatively high. At this time, the control module controls the first servo motor to drive the guide plate to rotate toward the opening of the recycling box by a preset angle, thereby increasing the range of the sorting box to receive toner; when the control module recognizes that the brightness of the sorted material in the photo transported by the industrial camera is higher than the predetermined threshold value, it means that the black toner content in the sorted material is relatively low. At this time, the control module controls the first servo motor to drive the guide plate to rotate away from the opening of the recycling box by a preset angle, thereby increasing the range of the recycling box to receive plastic particles. In summary, by taking real-time photos with the industrial camera, and then sorting plastic particles and toner according to the brightness of the obtained photos, the separation effect of particles and powder in the sorted material is further improved, the content of the carbonized layer in the old raw materials is reduced, and the problem of poor quality of the extruded board produced due to the carbonized layer in the old raw materials is improved.

[0017] Optionally, the conveyor belt is provided with a plurality of air nozzles for jetting air to the sorted material, the plurality of air nozzles are arranged at intervals along the width direction of the conveyor belt, and the air nozzles are arranged toward one end of the conveyor belt away from the crushing mechanism.

[0018] By adopting the above technical solution, when the sorting material is sorted, the sorting material is sprayed with air through the air nozzle, and the airflow drives the carbon powder to float toward the opening of the sorting box when it leaves the conveyor belt, thereby further improving the effect of separating the carbon powder and plastic particles.

[0019] Optionally, the plane where the air outlet of the air nozzle is located is arranged perpendicular to the conveying direction of the sorting material.

[0020] By adopting the above technical scheme, after the gas is ejected from the air outlet of the air nozzle, it diffuses along the inclined direction of the conveyor belt to blow the carbon powder, thereby avoiding as much as possible the change of the movement direction of the carbon powder by directly sending air toward the conveyor belt, improving the stability of the carbon powder during the movement, and further improving the separation effect of particles and powder in the sorting material, reducing the content of the carbonized layer in the old raw material, and improving the problem of poor quality of the extruded board produced due to the carbonized layer in the old raw material.

[0021] Optionally, an arc-shaped plate is provided at one end of the conveyor belt away from the crushing mechanism, and an inner arc surface of the arc-shaped plate is arranged toward the conveyor belt.

[0022] By adopting the above technical solution, when carbon powder falls from the conveyor belt, the inner arc surface of the arc plate guides the carbon powder, which, on the one hand, improves the accuracy of the carbon powder falling toward the opening of the sorting box, and on the other hand, the arc plate avoids the diffusion of carbon powder in the workshop as much as possible, thereby improving the environmental quality of the workshop.

[0023] Optionally, the conveyor belt is mounted on the ground via a mounting frame, the arc-shaped plate is rotatably mounted on the mounting frame, and an adjustment component for driving the arc-shaped plate to rotate is disposed on the mounting frame.

[0024] By adopting the above technical solution, when the sorting material needs to be sorted, the arc plate is driven to rotate to a suitable angle by adjusting the component, thereby improving the guiding effect of the carbon powder.

[0025] Optionally, frame plates are fixed at both ends of the arc plate, and the frame plates are rotatably connected to the mounting frame. The adjustment assembly includes a fixed crown gear fixed to the mounting frame, an adjustment rod telescopically connected to the frame plate along the rotation axis of the frame plate, and a moving crown gear fixedly sleeved on the adjustment rod, and the fixed crown gear and the moving crown gear are meshed with each other.

[0026] By adopting the above technical solution, when the sorting materials need to be sorted, the adjusting rod connected to the frame plate is telescopically driven to drive the moving crown gear to move in the direction away from the fixed crown gear until the moving crown gear and the fixed crown gear are no longer meshed, and then the arc plate is driven to rotate to a suitable angle, and then the moving crown gear is driven by the adjusting rod to move in the direction close to the fixed crown gear until it meshes with the fixed crown gear, thereby completing the adjustment process of the angle of the arc plate and improving the guiding effect on the carbon powder.

[0027] On the other hand, the present application provides a processing technology for an extruded board using the following technical solution:

[0028] A processing technology for an extruded board comprises the following steps:

[0029] S1: Loading: adding new raw materials, old raw materials and other materials into the loading device according to the preset proportion;

[0030] S2: Extrusion shaping, the material passes through the foaming extrusion device and the shaping device in sequence to obtain an extruded tape;

[0031] S3: Shaping and slitting: the extruded belt is transported to the shaping device through the conveying device for trimming and peeling to obtain waste material, which is then cut into extruded boards through the slitting device;

[0032] S4: waste recycling, the waste obtained in step S3 is melted and extruded into waste blocks for storage, after the waste blocks are stored to a predetermined amount, the waste blocks are crushed to obtain sorted materials, and the sorted materials are conveyed to the sorting mechanism through a conveyor belt to sort out particles and carbon powder;

[0033] S5: waste material utilization, the particles sorted out in step S4 are passed through a granulating device to obtain old raw materials, and the obtained old raw materials are used in step S1 to mix with new raw materials.

[0034] By adopting the above technical scheme, an extruded board is produced through a feeding device, a foaming extrusion device, a shaping device, a shaping device and a slitting device, and then the waste obtained by trimming and peeling the shaping device is melted and extruded into waste blocks for storage, and the plastic particles and carbon powder in the sorted material are stored separately by a crushing mechanism, a conveyor belt and a sorting mechanism, and finally the plastic particles are passed through a granulating device to obtain old raw materials, and the old raw materials are used in the production of extruded boards. On the one hand, the waste in the production process is recycled, and on the other hand, the content of the carbonized layer in the old raw materials is reduced, thereby improving the quality of the extruded boards produced using the old raw materials.

[0035] In summary, the present application includes at least one of the following beneficial technical effects:

[0036] 1. The obtained waste is melted and extruded into waste blocks for storage. When the stored waste blocks reach a predetermined amount, the waste blocks are broken into selected materials by a crushing mechanism. Since there is a carbonized layer in the waste blocks, the carbonized layer has a weak bonding effect with the plastic. Therefore, after the waste blocks are broken, selected materials containing carbon powder and plastic particles are formed. The selected materials are conveyed to the sorting mechanism through a conveyor belt, and the plastic particles and carbon powder are collected separately by the sorting mechanism. Finally, the collected plastic particles are made into granular old raw materials by a granulating device, so that the old raw materials are mixed with new raw materials and other materials and added to the feeding device, thereby reducing the content of the carbonized layer in the old raw materials and improving the problem that the old raw materials contain carbonized layers, resulting in poor quality of the extruded boards produced;

[0037] 2. When the sorted material is transported by the conveyor belt to the end away from the crushing mechanism, the industrial camera takes a photo of the sorted material on the conveyor belt and transmits the signal to the control module. When the control module recognizes that the brightness of the sorted material in the photo transported by the industrial camera is lower than a predetermined threshold value, it indicates that the black toner content in the sorted material is relatively high. At this time, the control module controls the first servo motor to drive the guide plate to rotate toward the opening of the recycling box by a preset angle, thereby increasing the range of the sorting box receiving toner; when the control module recognizes that the brightness of the sorted material in the photo transported by the industrial camera is higher than a predetermined threshold value, it indicates that the black toner content in the sorted material is relatively low. At this time, the control module controls the first servo motor to drive the guide plate to rotate away from the opening of the recycling box by a preset angle, thereby increasing the range of the recycling box receiving plastic particles. In summary, by taking real-time photos with the industrial camera, plastic particles and toner are sorted according to the brightness of the obtained photos, thereby further improving the separation effect of particles and powder in the sorted material;

[0038] 3. An extruded board is obtained by a feeding device, a foaming extrusion device, a shaping device, a shaping device and a slitting device, and then the waste materials obtained by trimming and peeling by the shaping device are melted and extruded into waste blocks for storage, and the plastic particles and carbon powder in the sorted materials are stored separately by a crushing mechanism, a conveyor belt and a sorting mechanism, and finally the plastic particles are passed through a granulating device to obtain old raw materials, and the old raw materials are used in the production of extruded boards. On the one hand, the waste materials in the production process are recycled, and on the other hand, the content of the carbonized layer in the old raw materials is reduced, thereby improving the quality of the extruded boards made of the old raw materials.

DETAILED DESCRIPTION

[0045] The following is combined with Figure 1-4 This application is described in further detail.

When the extruded board is produced, the new raw material, the old raw material and other materials are heated, stirred, mixed and conveyed to the foaming extrusion device 2 according to a predetermined ratio through the feeding device 1 for foaming and expansion extrusion, and then the extruded belt of predetermined thickness and width is produced through the shaping device 3. The extruded belt is conveyed by the conveying device 4 to pass through the shaping device 5 and the slitting device 6 in sequence. The shaping device 5 trims and peels the extruded board, and the slitting device 6 cuts the extruded belt into extruded boards of predetermined length. After the extruded board is obtained by cutting, the waste is melted and extruded into waste blocks by an extruder and then stored. After the stored waste blocks reach a predetermined amount, the waste blocks are crushed into selected materials by a crusher. The conveyor belt 10 conveys the selected materials to the sorting mechanism 9. The plastic particles and carbon powder in the selected materials are separated and stored separately by the sorting mechanism 9. Finally, the plastic particles are re-melted, extruded and pelletized by a plastic granulator to make old raw materials for making extruded boards.

[0048] In order to facilitate the collection of plastic particles and carbon powder in the sorting material, refer to Figure 2 The conveyor belt 10 is inclined, and its end close to the discharge port at the lower end of the crusher is lower than its end close to the sorting mechanism 9. The conveyor belt 10 is erected on the ground through a mounting frame 8. The mounting frame 8 includes two guide plates 82 arranged parallel to each other, a plurality of conveyor rollers 83 rotatably connected between the two guide plates 82, and a plurality of support rods 81. One end of the plurality of support rods 81 is fixed on the guide plate 82, and the other end is vertically abutted against the ground. The conveyor belt 10 is sleeved on the plurality of conveyor rollers 83.

[0049] Reference Figure 2 and Figure 3 The sorting mechanism 9 includes a recovery box 91 for receiving particles, a sorting box 92 for receiving carbon powder, and a control component 93 for guiding carbon powder into the sorting box 92 according to the content of carbon powder in the sorting material. The tops of the sorting box 92 and the recovery box 91 are both opened, and are both located below the end of the conveyor belt 10 away from the crusher. The planes where the openings of the sorting box 92 and the recovery box 91 of the conveyor belt 10 are located are staggered in the vertical direction, and the opening of the recovery box 91 is located on the side of the opening of the sorting box 92 close to the conveyor belt 10. Specifically, the recovery box 91 and the sorting box 92 are both set in a rectangular shape, the opening area of ​​the sorting box 92 is smaller than the opening area of ​​the recovery box 91, and the recovery box 91 is placed on the ground below the highest end of the conveyor belt 10. The cover of the sorting box 92 is set on the side of the opening of the recovery box 91 away from the conveyor belt 10, and a space is left for plastic particles to fall into the recovery box 91.

[0050] Reference Figure 3 In order to facilitate adaptive guidance of the carbon powder according to the content of the carbon powder in the sorting material, the control component 93 includes an industrial camera 931 for taking pictures of the end of the conveyor belt 10 away from the crushing mechanism 13, a control module 932 for receiving the signal of the industrial camera 931, a guide plate 933 rotatably connected to the side of the opening of the sorting box 92 close to the conveyor belt 10, and a first servo motor 934 whose output end is fixed on the guide plate 933, the rotation axis of the guide plate 933 is set parallel to the width direction of the conveyor belt 10, and the rotation axis of the output end of the first servo motor 934 coincides with the rotation axis of the guide plate 933, one side of the guide plate 933 extends to the side of the sorting box 92 close to the conveyor belt 10, and the first servo motor 934 and the control module 932 are electrically connected.

[0051] When the carbon powder content in the sorting material is high, the brightness of the sorting material photographed by the industrial camera 931 is lower than the threshold value. At this time, the control module 932 drives the first servo motor 934 to drive the material guide plate 933 to rotate a preset angle toward the recycling box 91; when the carbon powder content in the sorting material is low, the brightness of the sorting material photographed by the industrial camera 931 is higher than the threshold value. The control module 932 drives the first servo motor 934 to drive the material guide plate 933 to rotate a preset angle in the direction away from the recycling box 91.

[0052] In order to facilitate the guidance of toner and prevent it from scattering in the workshop, refer to Figure 3 The end of the conveyor belt 10 away from the crushing mechanism 13 is provided with an arc plate 12, which is set to be a quarter cylinder, and the inner arc surface of the arc plate 12 is set toward the conveyor belt 10. Specifically, the industrial camera 931 is fixed on the inner arc surface of the arc plate 12, and its camera direction is set along the radial direction of the inner arc surface of the arc plate 12. The control module 932 is fixed on the outer arc surface of the arc plate 12 and is electrically connected to the industrial camera 931; both ends of the arc plate 12 are fixed with frame plates 17, and the two frame plates 17 are respectively rotatably connected to the sides of the two guide plates 82 that are close to each other, and the guide plates 82 are provided with an adjustment component 7 for driving the arc plate 12 to rotate.

[0053] In the embodiment of the present application, the adjustment assembly 7 includes a fixed crown gear 71 fixed on the guide plate 82, an adjustment rod 73 telescopically connected to the frame plate 17 along the rotation axis of the frame plate 17, and a movable crown gear 72 fixedly sleeved on the adjustment rod 73, and the fixed crown gear 71 and the movable crown gear 72 are meshed with each other. Further, the adjustment rod 73 is set as an elastic telescopic rod, and the telescopic direction of the elastic telescopic rod is set along the rotation axis of the frame plate 17. In order to facilitate the elastic telescopic rod to be extended and rotated, a cross bar 16 is vertically fixed to one end of the elastic telescopic rod away from the frame plate 17, and the middle part of the cross bar 16 is fixedly connected to the elastic telescopic rod.

[0054] When the position of the arc rod needs to be adjusted, the cross bar 16 is driven to drive the moving crown gear 72 to move away from the fixed crown gear 71 through the elastic telescopic rod until the moving crown gear 72 is no longer engaged with the fixed crown gear 71, and then the arc plate 12 is driven to rotate to a suitable angle. Then, under the elastic retraction action of the elastic telescopic rod, the moving crown gear 72 moves toward the fixed crown gear 71 until it is engaged with the fixed crown gear 71, thereby completing the angle adjustment process of the arc plate 12.

[0055] In other embodiments, the adjustment component 7 also includes a second servo motor fixedly connected to the frame plate 17, and the second servo motor is electrically connected to the control module 932; when the carbon powder content in the sorting material is high, the brightness of the sorting material photographed by the industrial camera 931 is lower than a threshold value, and at this time the control module 932 drives the second servo motor to drive the side of the arc plate 12 close to the recycling box 91 to rotate a preset angle in the direction away from the recycling box 91; when the carbon powder content in the sorting material is low, the brightness of the sorting material photographed by the industrial camera 931 is higher than a threshold value, and the control module 932 drives the second servo motor to drive the side of the arc plate 12 close to the recycling box 91 to rotate a preset angle in the direction close to the recycling box 91.

[0056] Reference Figure 2 and Figure 3 The conveyor belt 10 is provided with a plurality of air nozzles 15 for jetting the sorted materials. The plurality of air nozzles 15 are arranged at intervals along the width direction of the conveyor belt 10, and the air nozzles 15 are arranged toward the end of the conveyor belt 10 away from the crusher. Specifically, a mounting cylinder 14 is mounted on the two guide plates 82, and the length direction of the mounting cylinder 14 is arranged along the width direction of the conveyor belt 10. The plurality of air nozzles 15 are evenly spaced and embedded in the mounting cylinder 14 along the length direction of the mounting cylinder 14, and the plurality of air nozzles 15 are connected to an external air pump. Furthermore, in order to prevent the gas ejected from the air nozzle 15 from interfering with the floating direction of the carbon powder as much as possible, refer to Figure 2 The plane where the air outlet of the air nozzle 15 is located is set perpendicular to the conveying direction of the sorting material, that is, the jet direction is parallel to the length direction of the conveyor belt 10. After the gas is sprayed out from the air outlet of the air nozzle 15, it diffuses during the movement along the length direction of the conveyor belt 10, thereby helping the carbon powder to fall into the sorting box.

[0057] The implementation principle of an extruded board production line in Example 1 of the present application is as follows: when producing extruded boards, new raw materials, old raw materials and other materials are heated, stirred, mixed and conveyed to a foaming extrusion device 2 in a predetermined proportion through a feeding device 1 for foaming and expansion extrusion, and then an extruded belt of predetermined thickness and width is produced through a shaping device 3. The extruded belt is conveyed by a conveying device 4 and sequentially passes through a shaping device 5 and a slitting device 6. The shaping device 5 trims and peels the extruded board, and the slitting device 6 cuts the extruded belt into extruded boards of predetermined lengths. After the extruded board is obtained by cutting, the waste is melted and extruded into waste blocks by an extruder and then stored. After the stored waste blocks reach a predetermined amount, the waste blocks are broken into selected materials by a crusher, and air is sprayed toward the conveyor belt 10 through the air nozzle 15. The conveyor belt 10 conveys the selected materials to the top of the conveyor belt 10. The plastic particles in the selected materials fall into the recovery box 91 under the action of gravity, and the carbon powder falls along the arc surface of the arc plate 12 under the action of the airflow. The industrial camera 931 takes a picture of the selected materials, and the control module 932 is used to adaptively adjust the angle of the guide plate 933 to sort and collect the carbon powder, thereby separating the plastic particles and the carbon powder and storing them separately. Finally, the plastic particles are re-melted, extruded and pelletized by the plastic granulator to make the old raw materials for making extruded boards.

The carbon powder falls along the arc surface of the arc plate 12 under the action of the air flow. The industrial camera 931 takes a picture of the selected materials. The control module 932 adaptively adjusts the angle of the guide plate 933 to sort and collect the carbon powder, thereby separating the plastic particles and the carbon powder and storing them separately.
