Description

Technical Field

[0001] The present invention relates to the technical field of recycled material processing, and more particularly, to a method for processing recycled materials and a carrier. Background Art

[0002] In the field of wood product processing, the reuse of recycled materials is an important way to reduce production costs and resource waste. At present, when using recycled wood to make structural components such as pallet legs, it is usually necessary to sort, cut, and splice waste wood of different sizes. In the prior art, the short wood is usually lengthened by gluing or finger-jointing processes, and then machined into components of the required specifications by mechanical processing. Some methods also add metal or plastic connectors at the splicing parts to improve the structural strength. In addition, in order to improve the material utilization rate, some processes make the recycled materials into multi-layer composite boards, and use the staggered arrangement to reduce the influence of internal defects on the overall performance.

[0003] However, processing the sizes of recycled wood into fixed sizes will result in waste of materials. For those recycled woods with relatively thick original thicknesses, in order to reach the unified standard size, a large amount of cutting and thinning processes are often required. In this way, not only will the actual volume of available wood be greatly reduced, but also a large amount of scrap will be generated, which is often difficult to reuse and can only be discarded eventually.

[0054] In this embodiment, in the processing of recycled materials, after the recycled wood is sorted and cut, it is joined by gluing and finger-jointing processes, and metal / plastic connectors are used to enhance the structural strength, or it is made into cross-laminated composite boards to improve the utilization rate. However, the recycled wood with a relatively thick thickness needs to be cut and thinned a lot. This will not only greatly reduce the actual volume of available wood, but also generate a large amount of waste materials, reducing the efficient utilization of the recycled wood in the carrier 01. Therefore, to solve the above problems, the present invention provides a method for processing recycled materials, as Figure 1 shown, the method for processing recycled materials includes steps S10 to S60, and the following can be a detailed description of steps S10 to S60.

[0055] Step S10, perform preliminary treatment on the recycled material to obtain the treated material. The preliminary treatment may include operations such as surface cleaning and shape adjustment of the recycled material to make the recycled material meet the basic conditions required for subsequent processing. Among them, the thickness of the treated material is 35 mm - 38 mm.

[0056] Step S20, perform a splitting operation on the thickness direction of the treated material. Cut the material along the thickness direction through a cutting device to obtain the first regular material and the material before teeth. Among them, the thickness of the first regular material is 16 mm. In this way, only the material before teeth needs to be thickness-treated, thereby improving the processing efficiency of the load-bearing leg 12. Since the cutting saw blade will cause a loss of 3 mm, the thickness of the material before teeth is greater than or equal to 16 mm. After splitting the treated material, both the first regular material and the material before teeth can be put into use. Thus, after splitting the treated material, most of the materials can be effectively utilized, avoiding the generation of a large amount of scrap.

[0057] Step S30, perform a subtractive machining on the thickness of the material before teeth. The subtractive machining may include subtractive machining methods such as cutting, grinding, and milling to remove the excess part in the thickness direction of the material before teeth to obtain a regular material, making the material before teeth meet the dimensional requirements matching the first regular material. Since the thickness of the material before teeth is greater than or equal to 16 mm, only subtractive machining is required without additive machining, thereby reducing the processing procedures.

[0058] Step S40, perform a comb-tooth machining on at least one end in the length direction of the first regular material to form a toothed structure with a regular shape, obtaining the first material after teeth. Perform a comb-tooth machining on at least one end in the length direction of the regular material to form a toothed structure with a regular shape, obtaining the material after teeth. In this way, when connecting multiple first materials after teeth or multiple materials after teeth through the toothed structure of the first material after teeth or the material after teeth, the contact area at the teeth can be relatively large, so that the connection can be more stable after connection.

[0059] Step S50, connect multiple first tooth rear materials along the length direction of the first tooth rear material. The connection may include: coating the teeth with an adhesive, and then inserting the teeth of multiple first tooth rear materials into each other. For example, one end of two first tooth rear materials is processed into comb teeth, one first tooth rear material is processed into comb teeth at both ends, and the first tooth rear material processed into comb teeth at both ends is located in the middle. One end is connected to one end of the first tooth rear material processed into comb teeth, and the other end is connected to one end of the other first tooth rear material processed into comb teeth to obtain the first long board 21. Connect the tooth rear materials along the length direction of the tooth rear materials to obtain the long board material 22. Since the coating area of the tooth-shaped structure is relatively large, after coating the teeth with an adhesive, then insert multiple long board materials 22 into each other, so that the connection can be more stable. For example, one end of two regular materials is processed into comb teeth, one regular material is processed into comb teeth at both ends, and the regular material processed into comb teeth at both ends is located in the middle. One end is connected to one end of the regular material processed into comb teeth, and the other end is connected to one end of the other regular material processed into comb teeth.

[0060] Step S60, based on the first long board 21 and the long board material 22, after performing a predetermined operation on the first long board 21 and the long board material 22, obtain the load-bearing leg 12. Among them, the thickness of the load-bearing leg 12 is 32 mm - 38 mm, and the width of the load-bearing leg 12 is greater than the thickness of the processed material and less than twice the thickness of the processed material, so that the load-bearing leg 12 has a certain height to allow the forklift fork to enter and lift the carrier 01.

[0061] In this embodiment, step S30 may include steps S31 to S35, and the following may elaborate on steps S31 to S35.

[0062] Step S31, divide the tooth front materials into the first tooth front material, the second tooth front material, the third tooth front material, and the fourth tooth front material according to the thickness. Among them, the thickness of the first tooth front material may be greater than or equal to 16 mm and less than the first set thickness, the thickness of the second tooth front material may be greater than or equal to the first set thickness and less than the second set thickness, the thickness of the third tooth front material may be greater than or equal to the second set thickness and less than the third set thickness, and the thickness of the fourth tooth front material may be greater than or equal to the third set thickness.

[0063] The execution order of steps S32 to S35 is not in sequence.

[0064] Step S32, process the thickness of the first tooth front material to obtain the first regular material. For example, uniformly process all the first tooth front materials with a thickness of 16 mm - 16.9 mm into the first regular materials with a thickness of 16 mm.

[0065] Step S33: Process the thickness of the second pre-tooth material to obtain a second regularized material with a first set thickness. This allows most of the second pre-tooth materials to be processed into second regularized materials for use in the production of the load-bearing leg 12, and the loss of the second pre-tooth materials during the processing is relatively small.

[0066] Step S34: Process the thickness of the third pre-tooth material to obtain a third regularized material with a second set thickness. This allows most of the third pre-tooth materials to be processed into third regularized materials for use in the production of the load-bearing leg 12, and the loss of the third pre-tooth materials during the processing is relatively small.

[0067] Step S35: Process the thickness of the fourth pre-tooth material to obtain a fourth regularized material with a third set thickness. This allows most of the fourth pre-tooth materials to be processed into fourth regularized materials for use in the production of the load-bearing leg 12, and the loss of the fourth pre-tooth materials during the processing is relatively small.

[0068] In this embodiment, step S31 may include steps S311 to S315, and the following may provide a detailed description of steps S311 to S315.

[0069] Step S311: Based on the pre-tooth material, obtain the thickness specifications of the pre-tooth material and the quantity of the pre-tooth material corresponding to each thickness specification. For example, obtain the quantity of the pre-tooth material with a thickness of 16.7 mm and the quantity of the pre-tooth material with a thickness of 17.8 mm.

[0070] Step S312: Based on the minimum value A1 and the maximum value A2 of the pre-tooth material thickness specifications, obtain the predetermined range B of the pre-tooth material, where 0 < B ≤ (A2 - A1) / 4. For example, among all the pre-tooth materials, the pre-tooth material with the minimum thickness has A1 = 16.1 mm, and the pre-tooth material with the maximum thickness has A2 = 18.7 mm. Then the range of the predetermined range B is 0 < B ≤ (18.7 - 16.1) / 4, that is, 0 < B ≤ 0.65. Since the pre-tooth materials need to be divided into the first pre-tooth material, the second pre-tooth material, the third pre-tooth material, and the fourth pre-tooth material according to the thickness, when determining the value range, it is necessary to divide by 4 to make the thickness of the processed pre-tooth materials relatively uniform and avoid wasting too much material.

[0071] Step S313: Based on the predetermined range B, obtain the minimum value B1 and the maximum value B2 of the first concentrated thickness range. Where B2 = B1 + B, and A1 ≤ B1 < B2 ≤ A2. For example, A1 is 16.1 mm, A2 is 18.7 mm, B is 0.65 mm, and B1 is 17.2 mm. Then B2 = 0.65 + 17.2 = 17.85 mm. When obtaining B1 and B2, B1 and B2 cannot be equal to avoid the inability to implement subsequent steps.

[0072] Step S314: Based on M≥0.5*N, obtain the first difference P and the second difference Q. Where P = B1 - A1, Q = A2 - B2, M is the number of pre-tooth materials with a thickness from B1 to B2, and N is the total number of pre-tooth materials. For example, A1 is 16.1 mm, A2 is 18.7 mm, B is 0.65 mm, B1 is 17.2 mm, B2 is 17.85 mm, and the total number of all pre-tooth materials is 400. The number of pre-tooth materials with a thickness from 17.2 mm to 17.85 mm is greater than or equal to 200. Then, the pre-tooth materials with a thickness greater than or equal to 17.2 mm to 17.85 mm are processed into second regular materials with a thickness of 17.2 mm. P = 17.2 - 16.1 = 1.1 mm, Q = 18.7 - 17.85 = 0.85 mm. Thus, it can be ensured that the second regular material has a larger thickness and higher strength, while not processing the pre-tooth materials with a thickness of B1, improving the processing efficiency. It can also reduce the loss of pre-tooth material processing.

[0073] Step S315: Based on P > Q > 0, the first set thickness is P / 2 + A1, the second set thickness is B1, and the third set thickness is B2. For example, based on the case in Step S314, the first set thickness is 1.1 / 2 + 16.1 = 16.65 mm, the second set thickness is 17.2 mm, and the third set thickness is 17.85 mm. That is, the pre-tooth materials with a thickness from 16.1 mm to 16.64 mm are processed to obtain the first regular material with a thickness of 16.1 mm. The pre-tooth materials with a thickness from 16.65 mm to 17.19 mm are processed to obtain the second regular material with a thickness of 16.65 mm. The pre-tooth materials with a thickness from 17.2 mm to 17.84 mm are processed to obtain the third regular material with a thickness of 17.2 mm. The pre-tooth materials with a thickness from 17.85 mm to 18.7 mm are processed to obtain the fourth regular material with a thickness of 17.85 mm. Thus, it can be ensured that the second regular material, the third regular material, and the fourth regular material have a larger thickness and higher strength, while also reducing the loss of pre-tooth material processing.

[0074] In this embodiment, after executing Step S314, Step S316 can be executed, and the following can provide a detailed description of Step S316.

[0075] Step S316: Based on P = 0, the first set thickness is B2, the second set thickness is B2 + (A2 - B2) / 3, and the third set thickness is B2 + (A2 - B2) / 3 * 2. For example, when A1 = B1, A1 = 16.1 mm, A2 is 18.7 mm, and B is 0.65 mm, then the first set thickness is 16.75 mm, the second set thickness is 16.75 + (18.7 - 16.75) / 3 = 17.4 mm, and the third set thickness is 16.75 + (18.7 - 16.75) / 3 * 2 = 18.05 mm. That is, for the pre-tooth material with a thickness of 16.1 mm to 16.74 mm, the first regularized material thickness obtained is 16.1 mm. For the pre-tooth material with a thickness of 16.75 mm to 17.39 mm, the second regularized material thickness obtained is 16.75 mm. For the pre-tooth material with a thickness of 17.4 mm to 18.04 mm, the third regularized material thickness obtained is 17.4 mm. For the pre-tooth material with a thickness of 18.05 mm to 18.7 mm, the fourth regularized material thickness obtained is 18.05 mm. Thus, while ensuring that the thicknesses of the second, third, and fourth regularized materials are relatively large and their strengths are relatively high, the loss during the processing of the pre-tooth material can also be reduced.

[0076] In this embodiment, after step S313 is executed, step S317 is executed, and step S317 will be described in detail below.

[0077] Step S317: Based on M < 0.5 * N, the first set thickness is 17 mm, the second set thickness is 18 mm, and the third set thickness is 19 mm. For example, if the number of pre-tooth materials with a thickness from B1 to B2 is less than half of the total number of all pre-tooth materials, then directly process the thickness of the pre-tooth materials into: the first regularized material is 16 mm, the second regularized material is 17 mm, the third regularized material is 18 mm, and the fourth regularized material is 19 mm, thereby improving the processing efficiency of the pre-tooth materials.

[0078] In this embodiment, after step S314 is executed, step S318 can be executed, and step S318 will be described in detail below.

[0079] Step S318: Based on Q > P > 0, the first set thickness is B1, the second set thickness is B2, and the third set thickness is Q / 2 + B2. For example, when Q > P > 0, A1 = 16.1 mm, A2 = 18.7 mm, B1 = 16.5, B2 = 16.9 mm, then the first set thickness is 16.5 mm, the second set thickness is 16.9 mm, and the third set thickness is 0.8 / 2 + 16.9 = 17.3 mm. That is, for the pre-tooth material with a thickness of 16.1 mm to 16.49 mm, the first regularized material thickness obtained is 16.1 mm. For the pre-tooth material with a thickness of 16.5 mm to 16.89 mm, the second regularized material thickness obtained is 16.5 mm. For the pre-tooth material with a thickness of 16.9 mm to 17.29 mm, the third regularized material thickness obtained is 16.9 mm. For the pre-tooth material with a thickness of 17.3 mm to 18.7 mm, the fourth regularized material thickness obtained is 17.3 mm. Thus, while ensuring that the thicknesses of the second, third, and fourth regularized materials are relatively large and the strength is relatively high, the loss of pre-tooth material processing can also be reduced.

[0080] In this embodiment, after step S313, steps S3191 to S3193 are executed.

[0081] Step S3191: Based on M > 0.5*N, increase B1 to B3. Where B3 < B2, and the number of pre-tooth materials L with a thickness specification within B3 to B2 is 0.5*N. For example, when A1 = 16.1 mm, A2 = 18.7 mm, B = 0.65 mm, B1 = 17.2 mm, B2 = 17.85 mm, the total number of all pre-tooth materials is 400, the number of pre-tooth materials with a thickness between 17.2 mm and 17.85 mm is 280, the number of pre-tooth materials with a thickness of 17.2 mm is 10, and the number of pre-tooth materials with a thickness of 17.3 mm is 200, then B1 can be increased to B3, thereby reducing the processing times of the pre-tooth materials and also improving the strength of the pre-tooth materials after processing.

[0082] Step S3192: Based on obtaining B3, obtain the third difference R. Where R = B3 - A1.

[0083] Step S3193: Based on R > Q > 0, the first set thickness is R / 2 + A1, the second set thickness is B3, and the third set thickness is B2. In this way, when the quantity of the material before the teeth with a thickness of B3 is large, the second set thickness can be increased to B3, thereby reducing the processing times of the material before the teeth, improving the processing efficiency, and also the thickness of the material after processing before the teeth. For example, A1 is 16.1 mm, A2 is 18.7 mm, B is 0.65 mm, B1 is 17.2 mm, B2 = 17.85 mm, B3 is 17.3 mm, and R is 17.3 - 16.1 = 1.2 mm. The quantity L of the material before the teeth with a thickness specification within B3 to B2 is 0.5 * N. Then the first preset thickness is 1.2 / 2 + 16.1 = 16.7 mm, the second set thickness is 17.3, and the third set thickness is 17.85 mm. That is, for the material before the teeth with a thickness of 16.1 mm to 16.69 mm, the first regularized material thickness obtained is 16.1 mm. For the material before the teeth with a thickness of 16.7 mm to 17.29 mm, the second regularized material thickness obtained is 16.7 mm. For the material before the teeth with a thickness of 17.3 mm to 17.84 mm, the third regularized material thickness obtained is 17.3 mm. For the material before the teeth with a thickness of 17.85 mm to 18.7 mm, the fourth regularized material thickness obtained is 17.85 mm. Thus, while ensuring that the thicknesses of the second, third, and fourth regularized materials are relatively large and the strength is relatively high, the loss during the processing of the material before the teeth can also be reduced.

[0084] In this embodiment, step S10 may include step S11 to step S12, and the following may elaborate on step S11 to step S12 in detail.

[0085] Step S11: Perform a first pretreatment on the recycled material to obtain a preliminarily processed material. Among them, the first pretreatment includes removing the metal connectors on the recycled material.

[0086] Step S12: Perform a second pretreatment on the preliminarily processed material to obtain a processed material. Among them, the second pretreatment includes processing the surface in the width direction of the preliminarily processed material so that the distance in the thickness direction of the preliminarily processed material between any two points on the surface in the width direction of the preliminarily processed material is within a first set distance, and processing the surface in the thickness direction of the preliminarily processed material so that the shortest distance in the width direction of the preliminarily processed material between any two points on the surface in the thickness direction of the preliminarily processed material is within a second set distance, making the surface of the processed material flat except at both ends, avoiding the phenomenon of potholes, so that when bonding the material subsequently, it can be better connected, increasing the stability of the connection. At the same time, since combing processing is required at both ends in the length direction, there is no need to perform the second pretreatment on the preliminarily processed material, thereby saving time and improving efficiency.

[0087] In this embodiment, step S60 may include steps S61 to S63, and the following may elaborate on steps S61 to S63 in detail.

[0088] Step S61, as Figure 2 shown, based on obtaining the first long board 21 and the long board material 22, a plurality of first long boards 21 are connected along the width direction of the first long board 21 to form a first integral board, and a plurality of long board materials 22 are connected along the width direction of the first long board 21 to form an integral board material. Thus, the first integral board and the integral board material can be better processed, and an adhesive is coated between the first integral board and the integral board material, thereby improving the processing efficiency.

[0089] Step S62, as Figure 3 、 Figure 4 shown, based on obtaining the first integral board and the integral board material, the first integral board and the integral board material are connected along the thickness direction of the first integral board by adding an adhesive and applying pressure to form a composite laminate 02. The first integral board and the integral board material become an integral body, so that they can be better processed into the load-bearing legs 12.

[0090] Step S63, based on obtaining the composite laminate 02, the thickness direction of the composite laminate 02 is divided to obtain the load-bearing legs 12.

[0091] In this embodiment, as Figure 5 shown, the present invention provides a carrier 01, and the carrier 01 is applied to any one of the above-mentioned recycling material processing methods. The carrier 01 includes a carrier plate 11 and at least three load-bearing legs 12.

[0092] One side of the load-bearing leg 12 along its width direction is connected to one side of the width of the carrier plate 11 along the thickness direction. The length direction of the load-bearing leg 12 is perpendicularly arranged to the length direction of the carrier plate 11. At least three load-bearing legs 12 are sequentially arranged at intervals along the length direction of the carrier plate 11. A plurality of load-bearing legs 12 are arranged on the same side of the carrier plate 11 along the thickness direction. The thickness of the outer load-bearing legs 12 is greater than the thickness of the middle load-bearing legs 12. In this way, when a forklift lifts the carrier plate 11, usually due to operation accuracy issues, one side of the carrier plate 11 rises first and the other side falls first. The side that falls first will bear a greater force. Therefore, the load-bearing legs 12 located on both sides of the carrier plate 11 have a thicker thickness, so that the load-bearing capacity of the load-bearing legs 12 at both ends of the carrier plate 11 is stronger. Thus, when the forklift performs a lifting and lowering action on the carrier 01, the carrier 01 can land smoothly, avoiding the goods on the carrier plate 11 from tilting.

[0093] Those of ordinary skill in the art can understand that the above-mentioned embodiments are specific cases for implementing the present disclosure, and in actual applications, various changes can be made in form and details without departing from the scope of the present disclosure.
