Description

Technical Field

[0001] The invention relates to the technical field of wooden floor production and manufacturing, in particular to a locking processing device for ultra-micro solid wood flooring. Background Art

[0002] The manufacturing process of solid wood flooring often requires sawing to length or to remove defects, resulting in waste end products. In the past, much of this waste was used as boiler fuel. However, with the replacement of fuel-fired boilers with electric power boilers, this no longer requires waste end products. Furthermore, using this waste end product as fuel is essentially a waste of material, with relatively low added value.

[0003] In the existing technology, there is a desire to use end scraps as raw materials for solid wood floors to produce miniature or narrow solid wood floors. However, the width of the end scraps is 10mm to 25mm and the length is 90mm to 150mm, while the minimum processable width of existing lock processing equipment is about 30mm. Therefore, due to the processing limitations of existing equipment, this technical desire has not been realized.

[0004] To this end, the inventors have proposed a feasible technical solution for producing miniature solid wood floors using end scraps as raw materials for solid wood floors, and have applied for an invention patent with publication number CN110861182B, entitled "Method for producing narrow decorative solid wood floors." This invention patent discloses the following steps for producing flooring: S1. Taking a blank and forming a first long-side male tenon and a first long-side female tenon on both long sides of the blank; S2. Splitting the blank with the formed long sides longitudinally to form a first sub-stock and a second sub-stock; S3. Assembling the first sub-stock and the second sub-stock by fitting the first long-side male tenon and the first long-side female tenon to form a first intermediate stock; S4. Forming a second long-side male tenon and a second long-side female tenon on both long sides of the first intermediate stock, thereby forming a second intermediate stock; S5. Forming a sub-stock short-side male tenon and a sub-stock short-side female tenon on the short sides of the second intermediate stock; S6. Separating the first sub-stock from the second sub-stock to form the first sub-stock and the second sub-stock. The aforementioned process overcomes the problem of end scraps being too small and too wide to be processed by existing equipment. This allows them to be transformed into solid wood flooring, avoiding waste and increasing their added value. Furthermore, the installed ultra-micro flooring offers a level of refinement and visual appeal unattainable with traditional flooring. It can also be installed in combination with conventional flooring, creating a variety of large and small combinations. When used locally, it can serve as decorative wall panels or ceiling tiles, thus offering a wide range of applications.

[0005] However, although the above technical solution does not require improvement or adjustment of existing equipment, the long side male tenons and long side female tenons of the micro floor cannot be completed in a single feeding process. The sub-materials need to be repeatedly assembled, locked, and separated. Therefore, there are problems such as overly complicated processes and long production cycles. At the same time, this process method relies too much on manual operation, and the production line employs a large number of workers. Summary of the Invention

[0006] The purpose of the present invention is to overcome the above technical problems of overly complicated processes, long production cycles and high reliance on manual labor.

[0007] To achieve the above-mentioned purpose, the first embodiment of the present invention discloses a locking processing device for ultra-micro solid wood flooring, which at least includes a tenon processing system, wherein the tenon processing system includes a conveyor line capable of conveying along the x-axis, a clamping unit located above the conveyor line, a backrest arranged along the x-axis direction, and a combination tool unit located on the opposite side of the backrest, the clamping unit is located between the backrest and the combination tool unit on the side close to the backrest, and the clamping unit is pressed on the surface of the workpiece in the area close to the side of the backrest.

[0008] Preferably, the x-axial centerline of the conveying line is longitudinally aligned with the x-axial centerline of the pressing unit.

[0009] Preferably, the tenon processing system includes, in sequence, a first processing section for making the long-side female tenon structure and a second processing section for making the long-side male tenon structure. The first processing section includes a first conveyor line, a first clamping unit, a first backrest, and a first combination tool unit. The second processing section includes a second conveyor line, a second clamping unit, a second backrest, and a second combination tool unit. The first backrest and the second combination tool unit are arranged on the same side, and the first combination tool unit and the second backrest are arranged on the same side.

[0010] Preferably, the first backing and the second backing can enable the workpiece to be always transported along the same straight line in the x-axis direction.

[0011] Preferably, the original width of the workpiece plate surface is subtracted from the width required for cutting to produce the long-side female tenon structure to obtain a processed plate surface with a first width, and the x-axial centerline of the first conveying line and the first clamping unit is longitudinally aligned with the x-axial centerline of the processed plate surface.

[0012] Preferably, the width of the back of the workpiece is subtracted from the width required for cutting to produce the long side male tenon structure to obtain a processed back having a second width, and the x-axial centerline of the second conveying line and the second clamping unit is longitudinally aligned with the x-axial centerline of the processed back.

[0013] Preferably, the second backrest is composed of a plurality of backrest rollers with the roller shaft arranged along the y-axis direction and arranged along the x-axis direction. The backrest roller includes an upper backrest section and a lower backrest section in its length direction, and the roller diameter of the upper backrest section is larger than the roller diameter of the lower backrest section.

[0014] Preferably, the width of the conveying line and the width of the pressing unit both span the workpiece and the backrest.

[0015] Preferably, the lower bottom surface of the backrest is flush with the conveying surface of the conveyor line, and there is a gap of 0.2 mm to 0.5 mm between the upper top surface of the backrest and the pressing surface of the pressing unit.

[0016] Preferably, the tenon processing system sequentially includes a first processing section for making a long-side female tenon structure and a second processing section for making a long-side male tenon structure, the first processing section includes a first conveyor line, a first pressing unit, a first backer, and a first combined tool unit, the second processing section includes a second conveyor line, a second pressing unit, a second backer, and a second combined tool unit, the first backer and the second combined tool unit are arranged on the same side, and the first combined tool unit and the second backer are arranged on the same side;

[0017] A wax sealing unit for sealing the long side female tenon structure with wax is provided between the first processing section and the second processing section. The second backrest includes a mating limiting portion that cooperates with the long side female tenon structure. The vertical surface of the mating limiting portion abuts against the vertical surface of the long side female tenon structure. There is a gap of 0.2mm to 0.5mm between the non-vertical surface of the mating limiting portion and the non-vertical surface of the long side female tenon structure.

[0018] The second embodiment of the present application discloses a locking processing device for ultra-micro solid wood flooring, which at least includes a male tenon processing system, wherein the tenon processing system includes a conveyor line capable of conveying along the x-axis, a pressing unit located above the conveyor line, a backrest arranged along the x-axis, and a combined tool unit, wherein the combined tool unit includes a pair of milling tools respectively located on both sides of the conveyor line, the backrest includes a plurality of backrest segments, the backrest segments include backrest blocks respectively located on both sides of the conveyor line, and the backrest segments are arranged at intervals between two adjacent pairs of milling tool pairs; the pressing unit includes a plurality of pressing segments corresponding one-to-one to the milling tool pairs and the backrest segments, and the axial center line of the pressing segment is close to the side of the processed male tenon structure.

[0019] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The clamping unit should be located between the backing and the combined tool unit, close to the backing. This allows the clamping unit to hold the workpiece more firmly, even if the initial width of the workpiece is very narrow. This allows the long-side male and female tenons to be locked in one operation, at least doubling production efficiency. When this technical solution is applied to the preparation of two short male and female tenons, the short-side male and female tenons can be locked in one operation.

[0021] 2. If the width of the workpiece is too small, the pressing unit can be used to simultaneously press on the surface of the workpiece and the top surface of the backing. This allows the pressing rollers that make up the pressing unit to have sufficient roller length (or the width of the pressing unit) to provide sufficient pressing force. Similarly, allowing the conveyor line to span the workpiece and the backing allows the conveyor line to have sufficient width, making the transmission of the conveyor line more stable.

[0022] 3. Through the setting of the wax sealing unit, wax sealing can be completed at the same time as the tongue and groove production, thus improving the production and processing efficiency.

[0023] 4. By setting the wax sealing unit between the first processing section and the second processing section, a wax coating is formed on the surface of the long-side female tenon structure by spraying, which can reduce the friction between the surface of the long-side female tenon structure and the surface of the matching limiting part, as well as the heating effect caused by friction, so that the workpiece can smoothly pass through the setting section of the second backrest. Furthermore, compared with direct exposure to a general production environment, the clearance fit between the matching limiting part and the long-side female tenon structure and a certain degree of frictional heat generation can in turn slow down the solidification of the wax coating, allowing the wax to fully flow on the surface of the long-side female tenon structure, and a certain degree of molecular migration occurs, causing the wax to partially penetrate below the surface of the long-side female tenon structure, thereby improving the bonding effect between the wax coating and the surface of the long-side female tenon structure.

DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0034] Example 1

[0035] Reference Figure 1 、 Figure 2The illustrated locking device for an ultra-micro solid wood floor comprises at least a tenon processing system, which sequentially includes a first processing section for producing a long-side female tenon structure and a second processing section for producing a long-side male tenon structure. The first processing section includes a first conveyor line 11 capable of conveying along the x-axis, a first pressing unit 12 located above the first conveyor line 11, a first backer 13 arranged along the x-axis, and a first combined tool unit 14 located opposite the first backer 13. The second processing section includes a second conveyor line 21 capable of conveying along the x-axis, a second pressing unit 22 located above the second conveyor line 21, a second backer 23 arranged along the x-axis, and a second combined tool unit 24 located opposite the second backer 23. Obviously, in order to complete the production of the long-side female tenon structure and the long-side male tenon structure, respectively located on both sides, in one conveyance, the first backer 13 and the second combined tool unit 24 are arranged on the same side, and the first combined tool unit 14 and the second backer 23 are arranged on the same side.

[0036] Specifically, in this embodiment, the first clamping unit 12 is located between the first backing member 13 and the first modular tool unit 14, on the side closest to the first backing member 14; the second clamping unit 22 is located between the second backing member 23 and the second modular tool unit 24, on the side closest to the second backing member 24. In other words, regardless of which side of the locking mechanism is used, the clamping unit should be located between the backing member and the modular tool unit, on the side closest to the backing member. Furthermore, the clamping unit only clamps a portion of the workpiece W's surface, which is closer to the backing member.

[0037] Since the initial width B0 of the workpiece W is relatively narrow, and in order to make room for the combined tool unit, the width of the conveyor line and the width of the clamping unit should be smaller than the initial width B0 of the workpiece W. In this case, the widths of the conveyor line and the clamping unit are very narrow and the clamping effect on the workpiece W is limited. The inventors have creatively discovered that the view commonly held in the prior art that the x-axial centerline of the clamping unit should be longitudinally aligned with the x-axial centerline of the workpiece W or at least closer to one side of the combined tool unit is wrong. On the contrary, the clamping unit should be located between the backrest and the combined tool unit, on the side closer to the backrest.

[0038] Specifically, first, combined with Figure 1As shown, based on the structure of the long-side female tenon, the lower cutting position of the first combined tool unit 14 is located on the upper side of the workpiece W. In other words, the first combined tool unit 14 will remove part of the material on the upper side of the workpiece W by milling. The comprehensive force on the workpiece W during the milling process is shown as force F1, that is, toward the body of the workpiece W and at the same time toward the back of the workpiece W. At this time, if the first clamping unit 12 applies the clamping force on the workpiece W to its x-axial centerline, or even closer to the side of the first combined tool unit 14, it is obvious that the side of the workpiece W made of the long-side female tenon structure is easy to flip down, causing the entire workpiece W to flip over. However, if the first clamping unit 12 applies the clamping force on the workpiece W to the side closer to the first backrest 13, the force F1 will be partially offset to a certain extent, which will make the clamping of the workpiece W by the first clamping unit 12 more stable.

[0039] Secondly, combined Figure 2 As shown, based on the structure of the long-side male tenon, the lower cutting position of the second combined tool unit 24 is located on one side of the workpiece W. In other words, the second combined tool unit 24 will remove part of the material on the upper and lower parts of one side of the workpiece W through milling. However, the width of the material removed by milling in the lower part of this side is greater than that in the upper part. The comprehensive force on the workpiece W during the milling process is shown as force F2, that is, toward the body of the workpiece W and the plate surface of the workpiece W. At this time, if the second clamping unit 22 applies the clamping force on the workpiece W to its x-axial centerline, or even closer to the side of the second combined tool unit 24, it is obvious that the side of the workpiece W made of the long-side male tenon structure is prone to warping up, causing the entire workpiece W to flip over. However, if the second clamping unit 22 applies the clamping force on the workpiece W to the side closer to the second backrest 23, the force F2 will be partially offset to a certain extent, making the clamping of the second clamping unit 22 on the workpiece W more stable.

[0040] In summary, with the above structure, the clamping unit should be located between the backrest and the combined tool unit on the side close to the backrest. Even if the initial width B0 of the workpiece W is very narrow, the clamping unit can clamp the workpiece W more firmly.

[0041] The structure of the workpiece W after passing through the first processing section and the second processing section is as follows: Figure 3 shown.

[0042] In this embodiment, the width of the workpiece W is 25 mm, the length is 125 mm, and the thickness is 18 mm. The first conveyor line 11 and the second conveyor line 21 are both crawler conveyors or roller conveyors of the prior art. The first clamping unit 12 and the second clamping unit 22 are both composed of a plurality of clamping rollers with the roller shaft arranged along the z-axis direction and arranged along the x-axis direction, and the clamping rollers are both pneumatic clamping or mechanical clamping rollers of the prior art. The first backrest 13 and the second backrest 23 are metal fixed backrest bars. Preferably, the second backrest 23 is composed of a plurality of backrest rollers with the roller shaft arranged along the y-axis direction and arranged along the x-axis direction, and the backrest rollers include an upper backrest section 231 and a lower backrest section 232 in the roller length direction, and the roller diameter of the upper backrest section 231 is larger than the roller diameter of the lower backrest section 232. Specifically, the outer periphery of the roller of the upper backrest section 231 abuts against the upper vertical side of the long side female tenon structure, and the outer periphery of the roller of the lower backrest section 232 abuts against the lower vertical side of the long side female tenon structure, so that the displacement limiting force of the second backrest 23 on the workpiece W is horizontal.

[0043] As a preferred embodiment, in order to improve the feeding stability of the workpiece W in the tenon processing system, the first backrest 13 and the second backrest 23 can ensure that the workpiece W is always conveyed along the same straight line in the x-axis direction. Therefore, it is more preferred that a transition conveyor line is provided between the first conveyor line 11 and the second conveyor line 21. The transition conveyor line is a roller conveyor, and the x-axial centerline of the transition conveyor line is located between the x-axial centerlines of the first conveyor line 11 and the second conveyor line 21. Of course, because the width of the workpiece W is relatively small, it is also possible to not provide a transition conveyor line, so that the first conveyor line 11 and the second conveyor line 21 are directly connected.

[0044] As a preferred embodiment, the x-axial centerline of the conveyor line is longitudinally aligned with the x-axial centerline of the clamping unit. In other words, the x-axial centerline of the first conveyor line 11 is longitudinally aligned with the x-axial centerline of the first clamping unit 12, and the x-axial centerline of the second conveyor line 21 is longitudinally aligned with the x-axial centerline of the second clamping unit 22. The advantage of this arrangement is that it can, to a certain extent, avoid the misalignment of the forces exerted on the workpiece W by the conveyor line and the clamping unit, thereby affecting the balance between the forces exerted on the workpiece W by the two and the force exerted on the workpiece W by the combined tool unit.

[0045] As a preferred embodiment, the original width B0 of the workpiece W plate surface is subtracted from the width B1 required for cutting to produce the long-side female tenon structure to obtain a processed plate surface with a first width B2, and the x-axial centerline of the first conveyor line 11 and the first clamping unit 12 is longitudinally aligned with the x-axial centerline of the processed plate surface. The width of the back side of the workpiece W (the same as the original width B0 of the plate surface) is subtracted from the width B3 required for cutting to produce the long-side male tenon structure to obtain a processed back side with a second width B4, and the x-axial centerline of the second conveyor line 21 and the second clamping unit 22 is longitudinally aligned with the x-axial centerline of the processed back side.

[0046] The technology of this application is only aimed at improving the tenon processing system, and the technical problem solved by the technical solution of this application can be achieved only by improving the tenon processing system. Therefore, other structures used to constitute the lock processing device, such as the body, electrical system, control system, feeding system, discharging system, etc., can all adopt existing technologies and will not be elaborated in this embodiment.

[0047] Example 2

[0048] In this embodiment, the workpiece W has a width of 15 mm, a length of 105 mm, and a thickness of 18 mm. Since the workpiece W is narrower and shorter, the width of the conveyor line and the width of the pressing unit in Embodiment 2, based on Embodiment 1, both span the workpiece W and the backing. Furthermore, the pressing unit only presses on a portion of the surface area of ​​the workpiece W, which is closer to the backing.

[0049] Specifically, refer to Figure 4 As shown, the first conveyor line 11 is arranged below the workpiece W and spans the workpiece W and the first backing 13, and the first pressing unit 12 is arranged above the workpiece W and spans the workpiece W and the first backing 13. At this time, the first backing 13 is fixedly installed by screwing the fixing seat on its side. Figure 5 As shown, the second conveying line 21 is arranged below the workpiece W and spans the workpiece W and the second backer 23 , and the second pressing unit 22 is arranged above the workpiece W and spans the workpiece W and the second backer 23 .

[0050] By virtue of the above structure, when the width of the workpiece W is too small, by allowing the pressing unit to press on the surface of the workpiece W and the top surface of the backing at the same time, the pressing rollers constituting the pressing unit can have a sufficient roller length (or can be the width of the pressing unit) to provide sufficient pressing force. Similarly, allowing the conveyor line to span the workpiece W and the backing allows the conveyor line to have a sufficient width to make the transmission of the conveyor line more stable. Preferably, the conveyor lines of this embodiment (the first conveyor line 11 and the second conveyor line 21) are both roller conveyors.

[0051] As a preferred embodiment, the first backing 13 is a fixed metal backing bar, and the bottom surface of the first backing 13 is flush with the conveying surface of the first conveyor line 11. In other words, there is pressureless contact between the first conveyor line 11 and the first backing 13. There is a gap of 0.2mm to 0.5mm (e.g., 0.3mm) between the top surface of the first backing 13 and the pressing surface of the first pressing unit 12.

[0052] The second backrest 23 is a metal backrest bar with a matching limit portion 233, which is located on the side of the second backrest 23 body facing the workpiece W. The cross-sectional shape of the matching limit portion 233 matches the cross-sectional shape of the long side female tenon structure. Figure 3 As shown, for example, the long side female tenon structure of this embodiment includes an indentation W1, a slot portion W2 located below and connected to the indentation W1, and a locking groove W3 located below and connected to the slot portion W2. The end face of the indentation W1, the bottom of the slot portion W2, and the outer end face of the locking groove W3 constitute the three vertical surfaces of the long side female tenon structure. The matching limiting portion 233 correspondingly includes a tenon shoulder, a tenon tongue located below and connected to the tenon shoulder, a locking protrusion located on the bottom face of the tenon tongue, and a retreat portion located below and connected to the tenon tongue. The tenon shoulder, the tenon tongue, the locking protrusion, and the retreat portion correspond to the indentation W1, the slot portion W2, the locking groove W3, and the outer end face of the locking groove W3, respectively. The end face of the tenon shoulder, the end face of the tenon tongue, and the end face of the retreat portion constitute the three vertical surfaces of the matching limiting portion 233. The three vertical surfaces of the matching limit portion 233 respectively abut against the three vertical surfaces of the long side female tenon structure. In other words, the end surface of the tenon shoulder, the end surface of the tenon tongue, and the end surface of the retreat portion respectively contact and abut against the end surface of the indentation portion W1, the bottom of the slot portion W2, and the outer end surface of the locking slot W3. The non-vertical surface of the matching limit portion 233 has a gap with the non-vertical surface of the long side female tenon structure and does not contact it. By setting the matching limit portion 233, the displacement limiting force of the second backrest 23 on the workpiece W can be horizontal, and by setting the gap, the long side female tenon structure of the workpiece W can smoothly cooperate with the matching limit portion 233 and pass through the setting section of the second backrest 23 under rapid feeding. Preferably, the non-vertical surface of the matching limit portion 233 has a gap of 0.2mm to 0.5mm (for example, 0.4mm) with the non-vertical surface of the long side female tenon structure. By setting the above gap size, the stability of the second backrest 23 against the workpiece W can be improved while ensuring smooth cooperation between the long-side female tenon structure of the workpiece W and the matching limiter 233. A gap of 0.2 mm to 0.5 mm is provided between the upper surface of the second backrest 23 and the pressing surface of the second pressing unit 22.

[0053] Example 3

[0054] Based on Example 2, a wax sealing unit 30 is provided between the first and second processing sections for wax sealing the long-side female tenon structure. The wax sealing unit 30 can be any conventional method, for example, comprising a molten paraffin tank, an electric heater for heating the paraffin in the tank, a delivery pipeline, and a nozzle, through which the molten paraffin is sprayed onto the surface of the long-side female tenon structure.

[0055] By means of the above structure, by arranging the wax sealing unit 30 between the first processing section and the second processing section, the wax sealing can be completed while the tongue and groove are being made, thereby improving the production and processing efficiency. The paraffin coating formed on the surface of the long-side female tenon structure by spraying can reduce the friction between the surface of the long-side female tenon structure and the surface of the matching limiting portion 233, as well as the heating effect caused by the friction, so that the workpiece W can smoothly pass through the setting section of the second backrest 23. Furthermore, compared with direct exposure to a general production environment, the clearance fit between the matching limiting portion 233 and the long-side female tenon structure and a certain degree of frictional heat generation can in turn slow down the solidification of the paraffin coating, so that the paraffin is fully leveled on the surface of the long-side female tenon structure, and a certain degree of molecular migration occurs, so that the paraffin partially penetrates below the surface of the long-side female tenon structure, thereby improving the bonding effect between the paraffin coating and the surface of the long-side female tenon structure.

[0056] Example 4

[0057] The difference between Example 4 and Example 1 is that, Figure 7 A locking processing device for ultra-micro solid wood flooring is shown, wherein the tenon processing system includes a conveyor line 41 capable of conveying along the x-axis, a pressing unit located above the conveyor line, a backer arranged along the x-axis, and a combination tool unit. The combination tool unit includes a plurality of milling tool pairs 42, and the milling tool pairs include two combination tools located on both sides of the conveyor line 41, and the two combination tools are used for milling and forming partial shapes of male tenon structures or female tenon structures. Of course, the combination tool for making the male tenon structure is located on the same side of the conveyor line 41, and the combination tool for making the female tenon structure is located on the other side of the conveyor line 41. The backer includes a plurality of backer segments 43, and the backer segment 43 includes backer blocks located on both sides of the conveyor line 41.

[0058] In particular, the backing sections 43 are arranged at intervals between two adjacent pairs of milling tool pairs 42. The clamping unit includes a plurality of clamping sections 44 corresponding to the backing sections 43. The clamping section 44 is composed of 3 to 5 clamping rollers arranged along the x-axis direction. The clamping section 44 is arranged to avoid the milling tool pair 42. The axial centerline of the clamping section 44, that is, the roller centerline of the clamping roller, is close to the side of the processing male tenon structure. Preferably, the clamping section 44 is composed of 3 to 5 spindle-shaped clamping rollers. More preferably, the original width of the plate surface of the workpiece W is subtracted from the width required to cut for making the long-side female tenon structure to obtain a processing plate surface with a first width, and the x-axial centerline of the clamping section 44 is longitudinally aligned with the x-axial centerline of the processing plate surface.
