Description

Technical Field

[0001] The present invention relates to the technical field of coil processing, and specifically provides a method for processing the surface of a flexible coil, a processing mechanism, and a processing production line. Background Art

[0002] Currently, for the processing of wood-based panels, in addition to directly using the wood board raw materials, more often, a wood board body of the required size is first prepared as a substrate, and then wood veneer is attached to the substrate. The wood-based panels prepared in this way can meet the requirements in terms of both size and surface texture.

[0003] Although the wood-based panels obtained by the above method have their own market advantages, the wood veneer cannot be directly used as the final product, and sanding and wire drawing processing and other treatment operations need to be carried out on the surface of the wood veneer. By sanding, the surface of the wood veneer becomes smoother, and wire drawing forms a texture on the surface of the wood veneer.

[0004] Since the wood veneer itself is flexible, the conventional processing equipment applicable to hard wood-based panels cannot be applied to the processing of wood veneer. When using such equipment to sand the wood veneer, the wood veneer cannot maintain stable transportation while under the sanding force, but will have problems such as wrinkling, or the sanding intensity cannot meet the requirements.

[0005] Based on the above situation, the current processing method for such wood-based panels is to first paste the wood veneer on the substrate, and after the two are firmly bonded, then sand and wire draw the wood-based panel with the wood veneer pasted on it. Although this method can meet the processing requirements, the wood veneer needs to be reprocessed for each wood-based panel. In addition to the aforementioned pasting and other processes, the wood veneer also needs to be cut and spliced separately. The processing process of the wood veneer takes a long working time and affects the production efficiency of the product. Summary of the Invention

Detailed implementation manners

[0063] Next, the technical solutions in the embodiments of the present application 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 of 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.

[0064] Please refer to Figure 1 , the present application provides the following technical solutions:

[0065] A method for processing the surface of a flexible coil, which is used to process coils made of flexible materials, such as wood veneer, thin steel plate, rubber belt, etc. In this solution, processing wood veneer is taken as an example. This processing method includes the following steps:

[0066] S1. Prepare a conveying path for the coiled material to ensure that the coiled material can be conveyed along a straight path and that the conveying direction of the coiled material is its length direction. During implementation, the conveying direction is horizontal.

[0067] S2. The surface of the coil to be processed is surface A, and the side away from surface A is surface B. Confirm the processing area in the coil conveying path. The processing area is a long strip area on surface A, and the length direction of the processing area is perpendicular to the conveying direction of the coil. In actual implementation, surface A is the upper side of the coil being conveyed, and surface B is the lower side.

[0068] S3, applying a supporting force on the B side of the coil, the force direction of the supporting force is perpendicular to the conveying direction of the coil; the supporting force pushes the coil from the B side to the A side, and the supporting force forms a supporting area on the B side of the coil, the supporting area corresponds to the processing area; the processing area is located directly above the supporting area;

[0069] S4. Adjust the support area to make it an arc-shaped surface, with the middle of the processing area and the support area facing each other. The support area is in an arc shape, and the adjustment method of the support area is:

[0070] S401, obtaining material parameters of the coil to be processed, the material parameters including thickness, elastic modulus, bending strength and width of the coil;

[0071] S402: According to the material parameters obtained in S401, the center angle and radius of the arc surface of the support area are adjusted. The center angle and radius of the arc surface of the support area meet the following conditions:

[0072]

[0073] Where t is the thickness of the coil, D is the diameter of the curved surface of the support area, E is the elastic modulus of the coil, w is the width of the coil, σ b It is the flexural strength of the coil.

[0074] S5. Applying a processing force to the coil in the processing area, wherein the direction of applying the processing force is opposite to the conveying direction of the coil;

[0075] S6. Maintain the conveying of the coil and the application of processing force to process the surface of the coil. While the coil is being conveyed, a stretching force is applied to the coil, the direction of the stretching force is the width direction of the coil, and the stretching force is applied from the middle of the coil to both sides of its width.

[0076] Through the processing method of this solution, combined with the setting form of the support area, continuous surface treatment operations such as sanding and wire drawing can be carried out on the flexible veneer coil. The surface treatment of the coil can be continuously carried out until all the coil materials are processed. The effect of the support area in this solution can meet the support of the reaction force in the surface treatment operation of the coil, and at the same time ensure that the coil will not wrinkle due to force during the processing. And through this solution, only by substituting materials of different materials, the appropriate support area angle can be obtained to match different processing materials.

[0077] On the basis of the foregoing implementation solutions, the formula inference basis for the central angle and radius in this solution is as follows.

[0078] Taking the veneer to be processed as an example.

[0079] 1. Material parameters, that is, veneer parameters respectively include:

[0080] Thickness t (mm), elastic modulus E (GPa), flexural strength σ b (MPa).

[0081] The commonly used elastic modulus table of wood is as follows:

[0082]

[0083] 2. Taking the cylindrical roller structure as the support force providing structure of the support area, for the convenience of description, this structure is defined as the support conveying roller, and the parameters of the support conveying roller are as follows:

[0084] Diameter D 1 = D - t (mm), D is the diameter of the arc surface of the support area.

[0085] 3. The working condition parameters are as follows

[0086] Veneer tension t (N / m, applied by the tractor).

[0087] According to the above parameters, the relationship between the contact pressure and the bending stress is obtained.

[0088] The contact area of the veneer on the support roller is rectangular, with width w and length L.

[0089] Contact pressure distribution:

[0090] According to the Hertz elastic contact theory, the maximum pressure is concentrated in the center:

[0091]

[0092] Veneer flexural critical stress:

[0093] To avoid breaking the veneer, it is necessary to meet:

[0094]

[0095] Where M is the bending moment and I is the moment of inertia of the cross-section.

[0096] From the simply supported beam model, it can be obtained that:

[0097]

[0098] By combining, it can be obtained that:

[0099]

[0100] Based on the above analysis, the wrapping angle θ needs to satisfy the following two equations:

[0101]

[0102] Furthermore, the following equation can be obtained:

[0103]

[0104] Where t is the thickness of the coil, D is the diameter of the arc surface of the support area, E is the elastic modulus of the coil, w is the width of the coil, and σ b is the flexural strength of the coil.

[0105] According to the above formula, taking the following parameters as an example:

[0106] Veneer parameters:

[0107] t = 1mm, E = 12GPa, σ b = 45MPa;

[0108] Support conveying roller parameters:

[0109] Diameter D = 320mm;

[0110] Tension T = 650N / m.

[0111] Thus, it can be obtained that:

[0112] P max = 0.309N

[0113] cosθ ≤ 0.448

[0114] θ ≤ arccos0.448

[0115] θ ≤ 63.38°

[0116] Based on the above implementation, see Figure 2This solution provides a processing mechanism, which is applied to the aforementioned processing method; the surface to be processed of the coil 100 is surface A, and the side away from surface A is surface B. The processing mechanism includes a conveying support unit 11, a support adjustment unit 12 and a processing unit 13.

[0117] The conveying support unit 11 is located on the surface of the coil 100B to be processed, and can convey the coil 100 in a horizontal direction; the conveying support unit 11 includes a cylindrical supporting conveying roller 111, and the diameter D of the supporting conveying roller 111 is 1 =Dt; the upper part of the supporting conveying roller 111 is in contact with the B surface of the coil 100, and the area where the supporting conveying roller 111 and the coil 100 are in contact is the supporting area. The supporting conveying roller 111 is linked with the driving mechanism 112, and the driving mechanism 112 drives the supporting conveying roller 111 to rotate.

[0118] The support adjustment unit 12 is arranged at the front and rear sides of the support unit 11 relative to the conveying direction of the coil 100. The support adjustment unit 12 can adjust the support area of ​​the coil 100 on the conveying support unit 11; the support adjustment unit 12 can apply an extension force to the coil 100. The support adjustment unit 12 includes a positioning roller 121 and a limiting roller 122 respectively located on the A surface and the B surface of the coil 100. The positioning roller 121 is located on the A surface side of the coil 100; the limiting roller 122 is located on the B surface side of the coil 100. There is a gap between the positioning roller 121 and the limiting roller 122, and the coil 100 can pass through the gap. The positioning roller 121 and the limiting roller 122 can be raised and lowered in the vertical direction.

[0119] The processing unit 13 is arranged directly above the conveying support unit 11, and the processing unit 13 can move toward or away from the conveying support unit 11. The conveying direction of the coil 100 is horizontal; the processing unit 13 includes a processing roller 131, and the axis of the processing roller 131 and the supporting conveying roller 111 are on the same vertical plane. When the processing unit 13 needs to perform sanding operation, the processing roller 131 is a sanding roller, and a sanding belt 132 is arranged on the outer side of the processing roller 131. The diameter of the processing roller 131 is equal to the diameter of the supporting conveying roller 111. It is only necessary to adjust the processing roller 131 accordingly, adjust it to a sanding roller or a drawing roller, and the processing unit 13 can sand or draw the coil.

[0120] On the basis of the above implementation scheme, the positioning roller 121 and the limiting roller 122 are provided with an extension structure, through which an extension force can be applied to the coil 100; the extension structure is a spiral groove opened on the roller body of the positioning roller 121 and the limiting roller 122;

[0121] The spiral groove is distributed symmetrically from the middle of the positioning roller 121 and the limiting roller 122 to both sides; the spiral groove meets the following requirements:

[0122] h=k·t

[0123] Where h is the groove depth of the spiral groove, t is the thickness of the coil material, k is an empirical coefficient, and 0.1 ≤ k ≤ 0.6.

[0124] The spiral angle of the spiral groove is 45°, and the spiral groove is arranged in a cross structure with two opposite spirals on each side of the positioning roller 121 and the limiting roller 122.

[0125] On the basis of the above implementation, the outer layer of the positioning roller 121 is an elastic layer, which is provided with a coating layer of elastic material, and the outer layer of the limiting roller 122 is rigid. The rigid material is directly used as its roller body, or the outer layer is a rigid coating material.

[0126] Because the surface to be processed of the veneer is not a plane, the outer layer of the positioning roller 121 located on the upper side is an elastic layer, which can better apply an extension force to the veneer.

[0127] Different from the support conveying roller 111, the positioning roller 121 and the limiting roller 122 do not have additional power, and they are both driven roller bodies.

[0128] On the basis of the above implementation, the positioning roller 121 is rotatably connected to the positioning lifting frame, and the distance between the positioning roller 121 and the limiting roller 122 is adjusted through the positioning lifting frame to adapt to coils of different thicknesses.

[0129] On the basis of the above implementation, the roller body of the positioning roller 121 is hollow inside, and the threaded groove on it is a through groove penetrating the outer wall of the positioning roller 121. An airbag is arranged inside the roller body of the positioning roller 121, and the airbag is connected to an air pump. A sensor is arranged in the direction of the feeding side of the processing roller 131. The sensor can be an optical sensor such as a laser or an infrared ray, or a mechanical sensor such as a proximity switch, as long as it can make a feedback when there are wrinkles in the coil material on the side of the processing roller 131. If there are wrinkles, the airbag inside the positioning roller 121 is inflated, and the airbag slightly penetrates through the spiral groove to increase the resistance of the support adjustment unit 12 to the coil material and relieve the wrinkle problem. The sensor can also be linked to a warning component to give an audible and visual prompt.

[0130] This solution also provides a processing production line. Refer to Figure 3 , using the foregoing processing mechanism and processing method, this processing production line is used for processing flexible coil materials. With the conveying direction of the coil material 100 as the front, it includes a first sanding machine 200, a first wire drawing group, a second wire drawing machine 400, a second sanding machine 500, and a cleaning machine 600 arranged in sequence from the feeding to the discharging of the coil material 100. The first wire drawing group includes three first wire drawing machines 300 arranged in sequence. During operation, the coil material 100 uses the first sanding machine 200 as the feeding end and the cleaning machine 600 as the discharging end.

[0131] On the basis of the above implementation, refer to Figure 4 andFigure 5 The first sanding machine 200 includes a frame, and a processing mechanism 1 is arranged inside the frame. The first sanding machine 200 adopts a structural form with two processing rollers 131. The processing roller 131 is a sanding roller with a sand belt 132 arranged on the outside. That is, two processing rollers 131 and two supporting and conveying rollers 111 are arranged inside the first sanding machine 200. Three groups of support adjustment units are arranged inside the first sanding machine 200. Each group of support adjustment units 12 includes a positioning roller 121 and a limiting roller 122. One group of the three groups of support adjustment units 12 is arranged between the two processing rollers 131 and the supporting and conveying rollers 111, and one group is arranged on each side of the two processing rollers 131 and the supporting and conveying rollers 111.

[0132] The two supporting and conveying rollers 111 share a set of driving mechanisms 112. A servo motor drives the two supporting and conveying rollers 111 to rotate synchronously through a combination of a synchronous pulley and a synchronous belt, so as to realize the support and conveyance of the coil 100.

[0133] A tensioning roller is arranged above the processing roller 131 for tensioning the sand belt on the outside of the processing roller 131. The processing roller 131 and the tensioning roller are arranged on a lifting frame together. The lifting frame is vertically slidably connected to the frame. For the lifting structure of the lifting frame, a lead screw structure is adopted in this solution. The movement of the lifting frame is realized through the threaded connection between the lead screw and the lifting frame. A worm and worm gear combination is arranged between the lifting frame and the lead screw. One end of the worm extends to the outside of the frame to provide an adjustable position that can be manually adjusted, so that when manual adjustment is required, the lifting frame can be finely adjusted by manual operation.

[0134] Based on the above implementation, refer to Figure 6 and Figure 7 , the first wire drawing machine 300 is arranged on the front side of the first sanding machine 200. A set of processing mechanisms 1 are arranged inside each first wire drawing machine 300. The processing roller 131 of the first wire drawing machine 300 is a wire drawing roller.

[0135] The first wire drawing machine 300 also includes a fixedly arranged frame. One processing roller 131 and one supporting and conveying roller 111 are arranged inside the first wire drawing machine 300. The supporting and conveying roller 111 is linked with the driving mechanism 112, and the driving mechanism 112 drives the supporting and conveying roller 111 to rotate. A support adjustment unit 12 is arranged on each side of the processing roller 131 and the supporting and conveying roller 111. A lifting frame is also arranged inside the first wire drawing machine 300, and the processing roller 113 is lifted by the lifting frame.

[0136] Based on the above implementation, refer to Figure 8 , the second wire drawing machine 400 is arranged on the front side of all the first wire drawing machines 300. Three groups of processing mechanisms 1 are arranged inside the frame of the second wire drawing machine 400. The processing roller 131 inside the second wire drawing machine 400 is a wire drawing roller;

[0137] Inside the second wire drawing machine 400, there are three groups of processing rollers 131 and supporting and conveying rollers 111. The three supporting and conveying rollers 111 are driven by a common set of driving mechanisms 112, and the synchronous pulley and synchronous belt are also used for linkage. The second wire drawing machine 400 is provided with four groups of supporting and adjusting units 12, which are respectively located between and on both sides of the three groups of processing rollers 131 and the supporting and conveying rollers 111.

[0138] Based on the above implementation, refer to Figure 9 , the second sanding machine 500 is arranged on the front side of the second wire drawing machine 400. Inside the frame of the second sanding machine 500, there is a set of processing mechanisms 1, that is, the processing roller 131 inside the second sanding machine 500 is a sanding roller, and the number of the processing roller 131 and the supporting and conveying rollers 111 is one, and the number of the supporting units 12 is two, which are located on both sides of the processing roller 131 and the supporting and conveying rollers 111.

A supporting unit 12 is respectively arranged on the feeding side and the discharging side of the cleaning machine 600. Two brushing rollers 601 are arranged between the two supporting units 12, and a brush is arranged on the outer side surface of the brushing roller 601. The coil 100 passes through between the two brushing rollers 601.

[0140] In the discharging direction of the brushing roller 601, there is an air blowing assembly. The air blowing assembly includes two air blowing parts 602. Both of the two air blowing parts 602 are in a strip-shaped structure, and the surface facing the coil 100 is the air blowing surface. A number of pores distributed in an array are arranged on the air blowing surface. The inside of the air blowing part 602 is hollow, and is connected to an air pump through an air pipe, and air can be blown out towards the coil from the pores on the air blowing surface. The two air blowing parts are respectively arranged on the upper and lower sides of the coil 100, and are used for blowing and washing the A side and B side of the coil 100. The surface of the air blowing part 602 facing the coil 100 is an inclined surface, and the upper and lower air blowing surfaces form a horizontally placed "eight" - shaped structure, and the end with the large opening faces the feeding end, and the end with the small opening faces the discharging direction.
