Description

Technical Field

[0001] The present invention belongs to the technical field of extruded board processing, and specifically refers to a fluffing device for extruded boards that can recycle solid waste. Background Art

[0002] XPS extruded board (extruded polystyrene foam board) is a high-performance thermal insulation material. It uses polystyrene resin and polymer as the main raw materials, is heated and mixed, and a catalyst is added for foaming to make a rigid foam plastic board with a continuous closed-cell structure. This unique closed-cell structure enables the XPS extruded board to have excellent thermal insulation performance. Its high thermal resistance, low linearity, and low expansion ratio characteristics can effectively reduce heat transfer and maintain a stable indoor temperature.

[0003] In the processing of extruded boards, a fluffing machine is a key surface treatment device, mainly used to improve the physical properties of the board surface, increase the surface area and roughness. The rough surface makes the board have a stronger adhesion to materials such as cement mortar and adhesives, reducing the risk of falling off after construction. When the existing fluffing roller performs a fluffing operation on the surface of the extruded board, XPS debris will remain on the fluffing roller, and the debris accumulates between the burrs, which will affect the subsequent fluffing efficiency of the burrs on the surface of the extruded board. At the same time, the debris will scatter in the machine and the site and cannot be recycled in time, which will affect the normal operation of the equipment within a certain period. Therefore, there is an urgent need for a fluffing device that can self-clean and recycle debris. Summary of the Invention

[0019] 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments without creative efforts belong to the scope of protection.

[0020] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the embodiments.

[0021] In view of the problem that when the fluffing roller 10 performs fluffing operation on the surface of the extruded board, XPS debris will adhere between the fluffing burrs 11 on the roller surface and debris will accumulate, the embodiments of the present invention provide a fluffing device for extruded boards that can recycle solid waste, aiming to achieve self-cleaning of XPS debris on the surface of the fluffing roller 10. The device mainly includes a pair of fluffing rollers 10, a driver 20, and a dust removal cover 30.

[0022] As Figure 1 、 Figure 2 and Figure 3 shown, a pair of fluffing rollers 10 are arranged on the frame 01 and can be driven by the driver 20 to rotate relative to each other.

[0023] Among them, the two fluffing rollers 10 respectively include a first fluffing roller 10.1 and a second fluffing roller 10.2. The first fluffing roller 10.1 is located below the second fluffing roller 10.2, and there is a passage for the board to pass between the first fluffing roller 10.1 and the second fluffing roller 10.2. The first fluffing roller 10.1 and the second fluffing roller 10.2 rotate in opposite directions and are respectively arranged on the upper and lower sides of the passage. The rotational speeds of the first fluffing roller 10.1 and the second fluffing roller 10.2 are configured to be consistent with the conveying speed of the extruded board. When the extruded board passes through the passage, the first fluffing roller 10.1 and the second fluffing roller 10.2 respectively perform fluffing operations on the upper and lower sides of the board.

[0024] Furthermore, since the fluffing roller 10 will generate debris when performing fluffing operation on the surface of the extruded board, in order to timely clean and collect the debris to avoid debris accumulation in the working site, the dust removal cover 30 is arranged outside the fluffing roller 10. At the same time, the collected debris can be reused as raw materials to make extruded boards again.

[0025] Among them, the dust removal hood 30 includes a first dust removal hood 31 and a second dust removal hood 32. The first dust removal hood 31 and the second dust removal hood 32 are respectively distributed on the outer sides of the first raising roller 10.1 and the second raising roller 10.2. Through the first dust removal hood 31 covering the outer side of the first raising roller 10.1, the debris generated during the raising operation of the first raising roller 10.1 is adsorbed. At the same time, through the second dust removal hood 32 on the outer side of the second raising roller 10.2, the debris generated during the raising operation of the second raising roller 10.2 is adsorbed.

[0026] In some embodiments, both the first dust removal hood 31 and the second dust removal hood 32 are configured as semi-circular hoods, so that the dust removal hood 30 semi-covers the outer side of the raising roller 10.

[0027] Furthermore, the first dust removal hood 31 is arranged on the lower side of the first raising roller 10.1, and the second dust removal hood 32 is arranged on the upper side of the second raising roller 10.2. Air pipe connectors 33 are provided on both the first dust removal hood 31 and the second dust removal hood 32. The air pipe connectors 33 are connected to an external negative pressure device, and a negative pressure attraction is provided to the first dust removal hood 31 and the second dust removal hood 32 through the external negative pressure device.

[0028] Even further, a hood cavity 301 is provided between the first dust removal hood 31 and the first raising roller 10.1 and between the second dust removal hood 32 and the second raising roller 10.2. The air pipe connector 33 is connected to the hood cavity 301. During operation, the external negative pressure device is connected to the hood cavity 301 through the air pipe connector 33, so that the entire hood cavity 301 is in a negative pressure state. When the raising roller 10 in the dust removal hood 30 rotates to perform a raising operation on the surface of the extruded sheet, the debris generated during the raising process can flow along the inner wall of the hood cavity 301 under the negative pressure attraction and finally flow out from the air pipe connector 33. In this way, the XPS debris generated during the raising process is timely sucked and collected to prevent the debris from falling into the working area.

[0029] As Figure 5 shown, along the conveying direction of the sheet, brushes 40 are provided at both ends (the inlet end and the outlet end) of the first dust removal hood 31 and the second dust removal hood 32. The brush 40 includes a first brush 41 fixed to the first dust removal hood 31 and a second brush 42 fixed to the second dust removal hood 32. The distance between the first brush 41 and the second brush 42 is less than or equal to the thickness of the sheet.

[0030] In some embodiments, the brush 40 is made of a steel brush or a plastic brush, and the density of the bristles is relatively large. On the one hand, the brush 40 can contact the surface of the sheet after raising to increase the roughness of the XPS extruded sheet after raising. On the other hand, the relatively dense distribution of the bristles can play a certain role in blocking the airflow, so that a relatively closed space is formed in the hood cavity 301 to prevent the XPS debris from escaping outward.

[0031] As Figure 4and Figure 5 As shown, the structure of the roughening roller 10 is a hollow cylinder. There is a roller cavity 101 inside the roughening roller 10, which is communicated with an external air supply device. A number of evenly distributed roughening spikes 11 are fixedly arranged on the outer side wall of the roughening roller 10.

[0032] In some embodiments, the roughening roller 10 is integrally made of stainless steel to form a hollow cylinder with a wall thickness of 2 - 3 mm, so that there is a roller cavity 101 inside the roughening roller 10. At the same time, the roller cavity 101 is connected to an external air supply device, and the air supply device supplies air into the roller cavity 101.

[0033] Furthermore, the roughening roller 10 performs a roughening operation on the surface of the extruded board through the roughening spikes 11 arranged in a matrix on its outer wall. When the roughening spikes 11 come into contact with the surface of the extruded board, they can pierce the surface of the extruded board to increase the surface roughness of the extruded board. Since a number of roughening spikes 11 are densely distributed, when multiple roughening spikes 11 jointly pierce the surface of the extruded board, the area between several roughening spikes 11 will be pulled off, and the fallen XPS debris may adhere between the roughening spikes 11 and cannot be separated in time, resulting in the roughening spikes 11 in this area losing the roughening effect in the subsequent process.

[0034] Therefore, in order to timely clean the XPS debris attached between the roughening spikes 11, air guide holes 100 are provided on the peripheral sides of the roughening spikes 11. The air guide holes 100 are communicated with the roller cavity 101 and can direct the air flow to the surface of the roughening spikes 11.

[0035] In this way, during operation, the external air supply device supplies air into the roller cavity 101 of the roughening roller 10. The gas inside the roller cavity 101 will be discharged from the air guide holes 100 around the roughening spikes 11. The air guide holes 100 direct the air flow along the surface of the roughening spikes 11, so that the air flow flows out along the surface of the roughening spikes 11. When the roughening spikes 11 perform a roughening operation on the extruded board, the air flow passes through the roughening spikes 11 and blows towards the surface of the extruded board. When XPS debris adheres around the roughening spikes 11, under the action of the air flow, the XPS debris can be timely blown off.

[0036] As Figure 5 shown, during the process of the roughening roller 10 working, the surface of the roughening roller 10 blows air out through the air guide holes 100. Cooperating with a dust removal cover 30 connected to an external negative pressure device, a negative pressure chamber 301 is formed between the dust removal cover 30 and the roughening roller 10. The XPS debris blown off from the surface of the roughening roller 10 will flow along the chamber 301 under the action of the air flow and be sucked and collected, so as to ensure that all the fallen XPS debris can be timely sucked and collected during the roughening operation of the roughening roller 10.

[0037] In some embodiments, an external air supply device can input air flow at a set temperature into the fluffing roller 10, so that the fluffing roller 10 not only has a self-cleaning function, but also can heat the fluffing roller 10, heat-press specific patterns on the surface of the sheet by the fluffing roller 10, and at the same time utilize the thermoplastic shaping texture of the XPS material to increase the surface roughness of the extruded sheet. Compared with the electric heating method, the air flow heating makes the temperature of the fluffing roller 10 more stable and is not easy to damage the surface of the extruded sheet.

[0038] In some embodiments, the fluffing burrs 11 are configured as conical, pyramidal or needle-shaped structures, and two to four air guide holes 100 are arranged on the circumferential side of each fluffing burr 11. The plurality of air guide holes 100 are configured to direct the air flow in the roller cavity 101 to the surface of the fluffing burrs 11 from different directions.

[0039] Furthermore, the air guide holes 100 are configured as tapered holes, and the end surface of the air guide hole 100 penetrating the outer side wall of the fluffing roller 10 is set as the first end surface, and the end surface of the air guide hole 100 penetrating the inner side wall of the fluffing roller 10 is set as the second end surface. The area of the first end surface is larger than the area of the second end surface.

[0040] In this way, when the air flow in the fluffing roller 10 flows outward through the air guide holes 100, through the guidance of the air guide holes 100, the XPS debris between the fluffing burrs 11 on the surface of the air guide holes 100 can be blown off, and the air guide holes 100 are set as tapered, and the tapered design of the air guide holes 100 prevents the XPS debris on the outside from entering the inside.

[0041] As Figure 4 and Figure 5 shown, an air supply roller 50 is arranged inside the fluffing roller 10. One end of the air supply roller 50 is fixed on the inner wall of the frame 01, and the fluffing roller 10 is rotatably installed outside the air supply roller 50.

[0042] In some embodiments, a main air supply channel 501 communicating with the external air supply device is arranged axially at the central position inside the air supply roller 50. A plurality of branch air supply channels 502 are arranged on the circumferential side wall of the air supply roller 50. The plurality of branch air supply channels 502 are symmetrically distributed around the main air supply channel 501. The branch air supply channels 502 communicate with the main air supply channel 501. The air flow of the external air supply device enters from the outside, and is successively distributed into the branch air supply channels 502 through the main air supply channel 501, and the air flow is evenly guided into the roller cavity 101 inside the fluffing roller 10.

[0043] As Figure 2 、 Figure 3 and Figure 4As shown in the figure, a first rotating shaft 10.11 penetrating through the frame 01 is fixedly provided at the end of the first roughening roller 10.1, and a second rotating shaft 10.21 penetrating through the frame 01 is fixedly provided at the end of the second roughening roller 10.2. A first gear 25 is fixedly provided on the first rotating shaft 10.11, and a second gear 26 is fixedly provided on the second rotating shaft 10.21. The first gear 25 and the second gear 26 are meshed with each other, so that the first roughening roller 10.1 and the second roughening roller 10.2 rotate in opposite directions.

[0044] Further, the driver 20 includes a motor 21 fixed to the frame 01 and a transmission mechanism arranged at the output end of the motor 21. The motor 21 drives the first gear 25 and the second gear 26 to rotate through the transmission mechanism.

[0045] In some embodiments, the transmission mechanism includes a driving wheel 22, a transmission belt 23 and a driven wheel 24. The driving wheel 22 is fixed to the output shaft of the motor 21, the driven wheel 24 is fixed to the shaft end of the first rotating shaft 10.11, and the transmission belt 23 is sleeved outside the driving wheel 22 and the driven wheel 24.

[0046] During operation, the driving wheel 22 on the output shaft of the motor 21 is driven to rotate by the motor 21, so that the driving wheel 22 drives the driven wheel 24 to rotate through the transmission belt 23, and the first rotating shaft 10.11 coaxially distributed with the driven wheel 24 rotates. The first gear 25 fixed on the first rotating shaft 10.11 and the second gear 26 on the second rotating shaft 10.21 are meshed with each other, so that the first roughening roller 10.1 and the second roughening roller 10.2 rotate in opposite directions, enabling the two roughening rollers 10 to rotate relative to each other and perform a roughening operation on the surface of the extruded board.

[0047] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or further includes elements inherent to this process, method, article or device.

[0048] The above describes the embodiments, and this description is not restrictive. What is shown in the drawings is only one of the embodiments, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by this and design similar structural modes and embodiments without creative efforts without departing from the creative purpose, they shall fall within the protection scope.
