Description

Technical Field

[0001] The invention relates to the technical field of floor mat production, and in particular to an aviation floor mat production device and process. Background Art

[0002] There are many ways to form PVC flooring. A common way to form PVC flooring mainly includes extrusion molding, cooling and shaping, and traction cutting. Extrusion molding is achieved through an extruder and a mold set on the extruder head. Cooling and shaping is located between extrusion molding and cutting. The PVC strip extruded by the extruder is cooled and shaped. Traction cutting includes traction, transverse cutting and longitudinal cutting. Transverse cutting is to use two cutting machines to cut the PVC sheet along the length direction of the PVC strip. Longitudinal cutting is to cut the PVC strip along the width direction of the PVC strip into pieces of PVC flooring that meet the product size.

[0003] A Chinese patent with authorization announcement number CN116353031B discloses a PVC floor forming device and a forming process, the device includes an extruder forming device, a cooling and shaping device and a traction and cutting device, the cooling and shaping device includes a frame, a lower cooling plate and an upper cooling plate, and also includes a lower driving device and an upper driving device and a controller respectively connected to the lower cooling plate and the upper cooling plate; the lower cooling plate and the upper cooling plate are both hollow structures, and cooling water is passed through the hollow structures of the lower cooling plate and the upper cooling plate, and the cooling water is provided by a chiller.

[0004] In the above technical solution, the water temperature of the cooling water inside the cooling plate is higher on the side close to the PVC material strip, but the water temperature is lower on the side away from the PVC material strip, which will cause stratification of the cooling water temperature. The uneven temperature of the cooling water will reduce the cooling efficiency of the PVC material strip. Moreover, the long-term use of the cooling plate will cause scale to form inside the cooling plate chamber, which will also affect the cooling efficiency. At the same time, the contact between the surface of the cooling plate and the PVC material strip will generate friction and thus cause wear on the material strip. Summary of the invention

[0005] The present invention provides an aviation floor mat production device and process, aiming to solve the technical problems in the related technology that the uneven temperature of cooling water will reduce the cooling efficiency of PVC material strips, and that the long-term use of the cooling plate will cause scale to form inside the cooling plate chamber, which will also affect the cooling efficiency, and the contact between the surface of the cooling plate and the PVC material strip will generate friction and thus cause wear on the material strip.

[0006] The invention discloses an aviation floor mat production device, comprising: an extruder, a cooling chamber, a cooling water tank, a fan and a cutting mechanism. The cooling chamber is provided with a plurality of groups of cooling rollers, each group having at least two cooling rollers. The cooling rollers are hollow structures and are rotatably installed in the cooling chamber. The cooling rollers are connected with the cooling water tank. A vortex plate is rotatably installed in the cooling rollers to disturb the cooling water in the cooling rollers. The vortex plate is coaxially arranged with the cooling rollers, and the outer end of the vortex plate contacts the inner wall of the cooling rollers. After the cooling water is injected into the cooling rollers, it slides to both sides along the outer wall of the vortex plate. The fan is connected with the cooling rollers, and the gas enters from the bottom of the cooling rollers, rises along both sides of the vortex plate, and can contact with the injected cooling water. The cooling rollers are also provided with blowing holes connected with the interior thereof, so that the gas is blown from the blowing holes to the surface of the material belt.

[0007] Beneficial effects: The extruder processes the raw materials into a material belt and conveys it to the cooling chamber for cooling. The material belt can pass through the bottom of the cooling roller below, turn around and then bypass the top of the cooling roller above, and finally enter the cutting mechanism for cutting. The cooling water tank can inject cooling water into the cooling roller through the water inlet hole. The driving mechanism can drive the vortex plate and the cooling roller to rotate. The cooling roller contacts the material belt to cool and convey the material belt. The rotation of the vortex plate can disturb the cooling water in the cooling roller and finally discharge it from the cooling roller, promoting the circulation of cooling water and ensuring the uniformity of water temperature. At the same time, the outer end of the vortex plate can scrape the inner wall of the cooling roller to avoid scale on the inner wall of the cooling roller. The fan can send gas into the cooling roller. The gas is discharged after filtering and cooling the cooling water and can be blown onto the material belt to further cool it. The cooling water temperature inside the cooling roller always remains uniform. At the same time, scale will not be generated on the inner wall of the cooling roller, which can ensure the cooling effect of the cooling roller on the material belt. At the same time, cold air can be blown to cool the material belt, effectively improving the cooling efficiency of the material belt.

[0008] Preferably, the axial length of the swirl plate is smaller than the axial length of the cooling roller, and one end of the two are flush.

[0009] The effect is that one end face of the swirl plate is flush with one end face of the cooling roller, which ensures the disturbance effect of the swirl plate and enables the gas entering the cooling roller to rise along both sides of the swirl plate.

[0010] Preferably, a filter element is slidably mounted at the center of the swirl plate, and the filter element can slide along the axial direction of the swirl plate.

[0011] The effect is that the cooling water inside the cooling roller can be filtered to ensure the cooling effect.

[0012] Preferably, the number of cooling rollers in each group is 2, and the two cooling rollers are arranged at intervals in the vertical direction.

[0013] The effect is that the material strip passes around the cooling roller in an S shape, thereby ensuring the cooling effect on the material strip.

[0014] Preferably, a plurality of rotating rollers are arranged on the outer peripheral side of the cooling roller, and the positions of the rotating rollers correspond to the blowing holes.

[0015] Preferably, a partition is fixedly installed on the vortex plate, one end of the partition is fixed at the center position of the vortex plate, and the other end is fixed to the side wall of the outer end of the vortex plate, and there is a gap with the outer end of the vortex plate, thereby forming an opening, and a filter plate is rotatably installed on the vortex plate, one end of which abuts against the end of the partition located at the opening, and a lever is rotatably installed on the vortex plate, and the rotation of the lever can press the filter plate to rotate the filter plate.

[0016] The effect is that the impurities floating in the cooling water can be gathered and filtered faster, so as to prevent the impurities from floating randomly in the cooling water and ensure the cooling effect of the cooling water.

[0017] Preferably, both ends of the partition are flush with both end surfaces of the cooling roller.

[0018] An aviation floor mat production process, using the aviation floor mat production device described above, comprises the following steps:

[0019] Step 1: The extruder processes the raw materials into a material strip and transports it to the cooling chamber;

[0020] Step 2: the material belt passes around the cooling roller, and the cooling roller rotates to transport the material belt;

[0021] Step 3: The cooling water tank injects cooling water into the cooling roller, and the vortex plate rotates to disturb and mix the cooling water to make the cooling water temperature uniform;

[0022] Step 4: The gas generated by the fan enters the interior of the cooling roller, where it contacts the cooling water. After being filtered and cooled, the gas is blown from the blowing hole onto the material belt to cool it down.

[0023] Step 5: After cooling, the material strip is conveyed to the cutting mechanism for cutting.

[0024] The effect is: when working, the cooling water tank can inject cooling water into the cooling roller through the water inlet hole, the cooling roller contacts with the material belt, cools down and transports the material belt, the vortex plate keeps rotating, the cooling water in the cooling roller can be continuously disturbed, the circulation is promoted, and the uniformity of water temperature is ensured. At the same time, the outer end of the vortex plate can scrape the inner wall of the cooling roller to avoid scaling of the inner wall of the cooling roller. The fan works continuously, and the generated gas can be sent into the cooling roller. The gas is filtered by the cooling water and cooled down before being discharged, and can be blown onto the material belt to further cool it down. The cooling water temperature inside the cooling roller is always kept uniform, and no scale is generated on the inner wall of the cooling roller, which can ensure the cooling effect of the cooling roller on the material belt, and can blow cold air to cool the material belt, effectively improving the cooling efficiency of the material belt.

[0025] By adopting the above technical scheme, the beneficial effects of the present invention are as follows: the cooling water in the cooling roller is disturbed by the rotation of the vortex plate to promote its circulation and ensure the uniformity of the water temperature; the outer end of the vortex plate can scrape the inner wall of the cooling roller to avoid scaling; the gas generated by the fan can be blown onto the material belt after filtering and cooling the cooling water to further cool it; the cooling water temperature inside the cooling roller always remains uniform; and at the same time, no scale is generated on the inner wall of the cooling roller, which can ensure the cooling effect of the cooling roller on the material belt and can blow cold air to cool the material belt, effectively improving the cooling efficiency of the material belt.

[0037] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0038] like Figures 1 to 9 As shown, a specific embodiment of an aviation floor mat production device of the present invention includes an extruder 10, a cooling chamber 20, a cooling water tank 21, a fan 24, a cooling roller 32, a vortex plate 40, a driving mechanism and a cutting mechanism 70.

[0039] The extruder 10 can heat the raw materials and process them into a material strip, and the material strip is cooled in the cooling chamber 20 and finally enters the cutting mechanism 70 for cutting.

[0040] A plurality of groups of cooling rollers 32 are arranged along the length direction of the cooling chamber 20 , each group has two cooling rollers 32 , and the two cooling rollers 32 are arranged with an interval up and down, the cooling roller 32 is a hollow cylindrical structure, the vortex plate 40 is arranged inside the cooling roller 32 , and the outer end of the vortex plate 40 is in contact with the inner wall of the cooling roller 32 .

[0041] The cooling water tank 21 is installed outside the cooling chamber 20 , and the cooling water can be injected into the cooling roller 32 through the water inlet hole 34 , and then discharged from the drainage pipe 23 and re-entered into the cooling water tank 21 .

[0042] The material strip can pass through the bottom of the lower cooling roller 32, and then pass around the top of the upper cooling roller 32 after turning.

[0043] The driving mechanism can drive the vortex plate 40 and the cooling roller 32 to rotate. The rotation of the vortex plate 40 can make the cooling water in the cooling roller 32 continuously flow along the vortex surface toward the center, and finally discharge the cooling roller 32, which can disturb the cooling water and promote its circulation. At the same time, the outer end of the vortex plate 40 can scrape the inner wall of the cooling roller 32 to avoid scaling.

[0044] The fan 24 is installed outside the cooling chamber 20 and is connected to the cooling roller 32. The gas can be sent into the cooling roller 32. The gas is filtered by cooling water and discharged after being cooled. The gas can be blown onto the material belt to further cool it.

[0045] During operation, the extruder 10 processes the raw materials into a material belt and conveys it to the cooling chamber 20 for cooling. The material belt can pass through the bottom of the cooling roller 32 below, turn around and then bypass the top of the cooling roller 32 above, and finally enter the cutting mechanism 70 for cutting. The cooling water tank 21 can inject cooling water into the cooling roller 32 through the water inlet 34. The driving mechanism can drive the vortex plate 40 and the cooling roller 32 to rotate. The cooling roller 32 contacts the material belt to cool and convey the material belt. The rotation of the vortex plate 40 can disturb the cooling water in the cooling roller 32 and finally discharge it from the cooling roller 32 to promote its circulation and ensure the uniformity of the water temperature. At the same time, the outer end of the vortex plate 40 can scrape the inner wall of the cooling roller 32 to avoid scaling. The fan 24 can deliver gas into the cooling roller 32. The gas is filtered by the cooling water and discharged after cooling. It can be blown onto the material belt to further cool it.

[0046] like Figure 2 A cooling water tank 21 is installed on the front side of the cooling chamber 20. The cooling water tank 21 is driven by a water pump to pump cooling water. A water inlet pipe 22 is connected to the cooling water tank 21. The water inlet pipe 22 is connected to the water inlet hole 34, and the cooling water can be transported to the cooling roller 32. A drainage pipe 23 is installed on the side of the cooling chamber 20, and the two ends are respectively connected to the cooling roller 32 and the cooling water tank 21, so that the cooling water in the cooling roller 32 can be discharged to the cooling water tank 21 to achieve a circulation effect.

[0047] like Figures 3 to 6 A plurality of groups of cooling rollers 32 are arranged in the cooling chamber 20 along its length direction, each group is provided with two cooling rollers 32, and the two cooling rollers 32 are arranged at intervals up and down. The front ends of the two cooling rollers 32 in each group are sealed and rotatably connected to the front side plates 31, and the rear ends are sealed and rotatably connected to the rear side plates 30. The front side plates 31 are fixedly mounted on the front side walls of the cooling chamber 20, and the rear side plates 30 are fixedly mounted on the rear side walls of the cooling chamber 20.

[0048] Water inlet holes 34 are provided at positions on the front side plate 31 corresponding to the cooling roller 32, and the water inlet holes 34 are located near the top of the cooling roller 32. The water inlet holes 34 are connected to the inside of the cooling roller 32 and are also connected to the water inlet pipe 22, so that cooling water can enter the cooling roller 32. The drainage pipe 23 is coaxially arranged with the cooling roller 32 and is connected thereto, so that the cooling water can be discharged through the drainage pipe 23 to achieve a circulation effect.

[0049] It is particularly noted that the amount of cooling water in the cooling roller 32 accounts for approximately half of the cooling roller 32, so as to ensure that the cooling water can be better disturbed when the vortex plate 40 rotates.

[0050] like Figures 7 to 9The cooling roller 32 is a hollow cylindrical structure. The vortex plate 40 is rotatably installed inside the cooling roller 32 and is coaxially arranged therewith. A rotating tube 63 is fixedly connected to the rear side of the vortex plate 40. The rotating tube 63 is rotatably installed on the rear side plate 30, thereby ensuring that the vortex plate 40 can rotate inside the cooling roller 32. The length of the vortex plate 40 is smaller than the length of the cooling roller 32, and the end faces of the two close to the front side are flush, that is, the front side end face of the vortex plate 40 is slidably matched with the front side plate 31, and there is a certain gap between the rear side surface of the vortex plate 40 and the rear side plate 30.

[0051] The direction of the outer opening of the vortex plate 40 is the direction of rotation, so that the cooling water can flow along the vortex surface of the vortex plate 40. The vortex plate 40 achieves a disturbance effect on the liquid. The temperature of the cooling water near the bottom of the cooling roller 32 is higher, and the temperature of the liquid near the top is lower. The disturbance of the liquid can make its temperature uniform and ensure the cooling effect. In addition, a filter element 41 is slidably installed at the center position of the vortex plate 40. The filter element 41 can slide along the axial direction of the vortex plate 40. The filter element 41 is connected to the drain pipe 23, so that the cooling water of the cooling roller 32 can be filtered by the filter element 41 and then discharged from the drain pipe 23 to the cooling water tank 21, and an opening is provided at the outer end of the drain pipe 23, which is sealed by a sealing cover, and the filter element 41 can be taken out through the opening for replacement.

[0052] The vortex plate 40 has an inner end and an outer end, and the outer end thereof contacts the inner wall of the cooling roller 32 , so that when the vortex plate 40 rotates, it can continuously scrape the inner wall of the cooling roller 32 to prevent scale from accumulating on the inner wall, thereby ensuring the cooling effect of the cooling roller 32 .

[0053] like Figure 6 and Figure 7 In this embodiment, air inlet holes 33 are provided at positions on the front side plate 31 corresponding to the cooling roller 32, and the air inlet holes 33 are located near the bottom of the cooling roller 32. A one-way valve is installed at the air inlet hole 33, and a ventilation pipe 25 is installed on the fan 24, and the air inlet hole 33 is connected to the ventilation pipe 25, so that the gas generated by the fan 24 can enter the interior of the cooling roller 32 through the air inlet hole 33.

[0054] An air outlet 35 is provided on the front side plate 31 near the top of the cooling roller 32, and the air outlet 35 is located on one side of the water inlet 34. An air blowing hole 51 is provided on the surface of the front side plate 31 opposite to the inner side of the rear side plate 30. A plurality of air blowing holes 51 are provided along the circumference of the cooling roller 32. In this embodiment, the air blowing hole 51 is located near the top of the cooling roller 32, and the air blowing hole 51 is connected to the air outlet 35. After the gas enters the cooling roller 32 through the air inlet 33, the gas Passing through the cooling water can not only cool the gas, but also filter out impurities in the gas. Then, after passing through the air outlet 35, the gas is blown out from the blowing hole 51. A plurality of rollers 50 are rotatably installed on the inner sides of the front side plate 31 and the rear side plate 30 relative to the air outlet 35. The rollers 50 are arranged axially along the cooling roller 32. The material belt can bypass the rollers 50, thereby creating a gap between the cooling roller 32 and the material belt. The gas is ejected from the air outlet 35 and blown onto the material belt, further helping to cool it down.

[0055] In particular, if Figure 6 , the front side of the vortex plate 40 is in conflict with the front side plate 31, and at the same time, the outer end of the vortex plate 40 is in conflict with the inner wall of the cooling roller 32, so when the outer end of the vortex plate 40 rotates to the left side of the air inlet hole 33, the left part of the air inlet hole 33 is sealed, and most of the gas will pass through from the right side and be discharged from the air outlet 35 after passing through the cooling water. Similarly, when the outer end of the vortex plate 40 rotates to the right side of the air inlet hole 33, the right part of the air inlet hole 33 is sealed, and most of the gas will pass through from the left side and be discharged from the air outlet 35 after passing through the cooling water. That is to say, when the vortex plate 40 rotates, the gas continues to move upward along both sides of the vortex plate 40.

[0056] The water inlet hole 34 is close to the top of the cooling roller 32, so when the cooling water enters the cooling roller 32, it will flow down along the two sides of the vortex plate 40, and then form convection with the upward moving gas. The gas contacts the coolant that has just entered the cooling roller 32. At this time, the temperature of the coolant is relatively low, which can further reduce the temperature of the gas, thereby improving the cooling effect on the material strip.

[0057] like Figure 4 and Figure 5The driving mechanism includes a motor 60 installed on the rear side of the cooling chamber 20, and a driving belt 61 is installed on the driving wheel of the motor 60. A driven wheel 62 is rotatably installed on the rear side plate 30. The rear side plate 30 is connected to all the driven wheels 62 in a transmission manner. A pulley 64 is fixedly installed on the outer side of the rotating tube 63. The driven wheel 62 is connected to the pulley 64 through a belt, and then the vortex plate 40 can be driven to rotate by driving the rotating tube 63 to rotate. A first gear 65 is also fixedly installed on the outer side of the vortex plate 40, and a second gear 66 meshing with the first gear 65 is rotatably installed on the rear side plate 30. A gear ring 67 fixedly connected to the cooling roller 32 is rotatably installed on the rear side plate 30, and the gear ring 67 is meshed with the second gear 66. When the first gear 65 rotates, the first gear 65 can be driven to rotate, thereby rotating the cooling roller 32. The upper and lower gear rings 67 are also meshed and connected, so that the upper and lower cooling rollers 32 can rotate synchronously with the vortex plate 40.

[0058] After working for a long time, more impurities will float in the cooling water inside the cooling roller 32, thereby affecting the cooling effect. In order to solve this problem, the present invention also proposes a further solution, which is as follows.

[0059] like Figure 8 and Fig. 9 A partition 42 is fixedly installed on the vortex plate 40, one end of the partition 42 is fixed at the center of the vortex plate 40, and the other end is fixed on the front and rear side walls of the outer end of the vortex plate 40, and there is a certain gap with the outer end of the vortex plate 40. The front and rear ends of the partition 42 are in contact with the front side plate 31 and the rear side plate 30 respectively, and then when the vortex plate 40 rotates, the cooling water is pushed into the opening between the partition 42 and the outer end of the vortex plate 40.

[0060] A filter plate 43 is rotatably mounted on the vortex plate 40, and one end of the filter plate 43 located on the outside abuts against the end of the partition plate 42 located at the opening, and the other end of the filter plate 43 faces the inside of the vortex plate 40 and is rotatably connected to the inner wall of the vortex plate 40, and a torsion spring is installed on the rotating end. When the vortex plate 40 rotates, cooling water needs to pass through the filter plate 43 after entering from the opening, thereby continuously filtering out floating debris in the cooling water, and gathering the debris on the filter plate 43 to prevent the debris from floating at will.

[0061] The filter holes of the filter plate 43 may be clogged. Fig. 9A lever 44 is rotatably mounted on the rear side of the scroll plate 40, and a torsion spring is arranged on the lever 44. An arc groove 45 is provided on the rear side wall of the scroll plate 40. When the scroll plate 40 rotates, a shift block (not shown in the figure) is fixedly mounted on the rear side plate 30 located on the rotation path of the scroll plate 40. The shift block squeezes the lever 44 to rotate along the arc groove 45, thereby pressing the side of the filter plate 43 located at the opening downward, so that the end is pressed against the inner side wall of the scroll plate 40, and the filter plate 43 The surface that contacts the partition 42 will move away from the partition 42, so that an opening will be re-formed between the filter plate 43 and the partition 42. When cooling water enters from the opening, it will impact the filter plate 43 and wash away the blocked debris. When the lever 44 passes through the lever block, it is affected by the force of the torsion spring, and the lever 44 and the filter plate 43 rotate and reset. This cycle prevents the filter plate 43 from being blocked and can collect floating debris. Finally, the debris will be washed into the filter element 41 along the water flow and filtered out by it.

[0062] The production process of the aviation floor mat production device according to the embodiment of the present invention includes the following steps:

[0063] Step 1: The extruder 10 processes the raw material into a material strip and conveys it to the cooling chamber 20;

[0064] Step 2: The material strip passes around the cooling roller 32, and the driving mechanism drives the cooling roller 32 and the vortex plate 40 to rotate to transport the material strip;

[0065] Step 3: The cooling water tank 21 injects the cooling water into the cooling roller 32 through the water inlet hole 34. After being filtered by the filter element 41, the cooling water re-enters the cooling water tank 21 from the drainage pipe 23. The vortex plate 40 rotates to disturb and mix the cooling water to make the cooling water temperature uniform.

[0066] Step 4: The gas generated by the fan 24 enters the cooling roller 32 through the air inlet 33, and contacts the cooling water. After being filtered and cooled, the gas is blown onto the material belt from the air blowing hole 51 to cool it down.

[0067] Step 5: After being cooled, the material strip is transported to the cutting mechanism 70 for cutting.

[0068] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
