Description

Technical Field

[0001] The present invention relates to the technical field of wood and bamboo material antiseptic storage, and in particular to a wood and bamboo material anti-mildew treatment method and treatment device. Background Art

[0002] Wood and bamboo (wood and bamboo materials) are widely used in daily life, handicrafts, and industry and commerce. However, after being harvested, wood and bamboo materials are rich in nutrients, such as sugars, starches, fibers, and oils. Under certain humidity and temperature conditions, mold can begin to grow, leading to mold growth. Furthermore, bamboo's fiber structure and grain structure are closely related. Bamboo's coarse fibers and grain make it easy for mold to hide within, creating a favorable environment for growth, damaging the bamboo's interior and causing discoloration. To minimize mold growth, bamboo should be stored in a dry, well-ventilated environment, protected from rain. Anti-mold treatment for wood and bamboo requires not only soaking and spraying the materials with anti-mold agents, but also sterilization, such as drying them in a dry place. Furthermore, properly sealing the materials is crucial for optimal mold prevention.

[0003] For example, in the prior art, the publication (announcement) number is CN111906873A, and the patent title is: A method for preventing mildew and corrosion of bamboo materials, which relates to the field of bamboo material anti-corrosion and storage technology. It includes the following steps: a. Dividing batches of bamboo materials into ready-to-use bamboo materials and spare bamboo materials, and placing them in two areas to be treated with mildew and corrosion respectively; b. Filling the first anti-corrosion and mildew treatment area with disinfectant, immersing the ready-to-use bamboo materials in the first anti-corrosion and mildew treatment area, taking out the ready-to-use bamboo materials and placing them in a sterile treatment chamber; c. After the ready-to-use bamboo materials have been sterilized, a single layer of extremely thin breathable film is used to cover the ready-to-use bamboo materials; d. Immersing the spare bamboo materials in the second anti-corrosion and mildew treatment area, taking out the spare bamboo materials and placing them in a sterile treatment chamber; e. After the spare bamboo materials have been sterilized, a single layer of extremely thin breathable film is used to cover the spare bamboo materials; f. The anti-corrosion and mildew operation of the bamboo materials is completed. After adopting the above technical solution, the beneficial effect of the present invention is: the bamboo material is fully free of mold by soaking in a non-damaging antiseptic agent, and can be preserved for a long time without the need for airtight sealing.

[0004] Among them, in step c or e of the above patents, it is necessary to cover the wood and bamboo materials with a coating film to isolate oxygen in order to achieve anti-corrosion and anti-mildew, and the sealing and preservation of the wood and bamboo materials is also a necessary means to cope with the harsh external environment. However, the anti-corrosion treatment of batches of wood and bamboo materials is often done manually in the existing technology, which has low work efficiency and cannot guarantee a good sealing effect. In order to improve this, it is necessary to design a method and a treatment device for anti-mildew treatment of wood and bamboo materials. Summary of the Invention

[0056] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0057] In the embodiments of the present invention, wood and bamboo materials refer to the wood and bamboo materials. The anti-mildew treatment device provided by the embodiments of the present invention can be applied to both wood and bamboo materials, but not other materials.

[0058] See also Figure 1-14 , a wood and bamboo material mildew-proof treatment device, comprising:

[0059] The workbench 1 is a mechanism for supporting the operation of the entire device. Its specific structural form is designed according to the specific operating mechanism. The two ends of the workbench 1 are respectively provided with an upper and lower double-layer unwinding mechanism and a traction mechanism. The upper and lower double-layer unwinding mechanism is used to unwind the covering film for wrapping wood and bamboo materials and to divide the covering film into upper and lower layers for synchronous unwinding. The traction mechanism is used to unidirectionally pull out the covering film unwound by the upper and lower double-layer unwinding mechanism. The covering film can be a material such as PE film that can withstand the traction force of the traction mechanism.

[0060] The feeding mechanism is arranged on the workbench 1 to evenly feed the wood and bamboo materials between the upper and lower layers of the covering film unwound by the upper and lower double-layer unwinding mechanisms. That is, when the traction mechanism pulls the covering film to move at a uniform speed, the feeding mechanism feeds the wood and bamboo materials into the inner sides of the upper and lower layers of the synchronously moving covering film at equal intervals;

[0061] And an edge sealing mechanism, which is arranged on the workbench 1 and located between the upper and lower double-layer unwinding mechanisms and the traction mechanism, is used to seal the edges of the upper and lower layers of synchronously unwound covering films so that the wood and bamboo materials are sealed within the upper and lower layers of covering films.

[0062] To sum up, the anti-mildew treatment method for wood and bamboo materials is implemented based on the above-mentioned anti-mildew treatment device for wood and bamboo materials, wherein the feeding mechanism is utilized to improve the efficiency of placing the wood and bamboo materials between the upper and lower layers of covering films, and the edge sealing mechanism is used to realize rapid sealing of the covering films, thereby improving the efficiency of sealing and wrapping the wood and bamboo materials during the anti-mildew treatment process and ensuring better sealing quality.

[0063] Furthermore, the upper and lower double-layer unwinding mechanism includes an upper unwinding mechanism arranged on the workbench 1 at one end opposite to the traction mechanism and a lower unwinding mechanism located below the upper unwinding mechanism.

[0064] The upper unwinding mechanism and the lower unwinding mechanism are both used for unwinding the covering film for covering wood and bamboo materials.

[0065] Furthermore, the lower unwinding mechanism and the upper unwinding mechanism are arranged symmetrically with each other;

[0066] The lower unwinding mechanism includes a lower unwinding roller 2 and a lower guide roller 3. The lower unwinding roller 2 is used to unwind the coating film and guide the coating film through the lower guide roller 3 so that the coating film moves on the workbench 1 under the traction of the traction mechanism.

[0067] The upper unwinding mechanism includes an upper unwinding roller 4 and an upper guide roller 5. The upper unwinding roller 4 is used to unwind the covering film and is guided by the upper guide roller 5 so that the covering film moves above the covering film unwound by the lower unwinding roller 2 under the traction of the traction mechanism.

[0068] Specifically, under the guidance of the respective lower guide rollers 3 and upper guide rollers 5, the covering film unwound from the lower unwinding roller 2 is pulled by the traction mechanism and moves on the workbench 1, carrying the wood and bamboo materials. The covering film unwound from the upper guide roller 5 is pulled by the traction mechanism and moves above the covering film unwound from the lower unwinding roller 2, that is, covering the wood and bamboo materials. Particularly, when the covering film enters the position above the workbench 1, with the support of the lower guide rollers 3 and upper guide rollers 5, there is space between the upper and lower layers of covering film to accommodate the entry of the wood and bamboo materials. Subsequently, the wood and bamboo materials are moved between the upper and lower layers of covering film to proceed with the subsequent process. Particularly, the position state between the upper and lower layers of covering film is as tight as possible. Figure 1 The upper and lower layers of covering film and the wood and bamboo materials between them are shown as schematic diagrams of the positions only and do not represent the actual style.

[0069] Furthermore, the traction mechanism includes two sets of traction rollers symmetrically arranged in an upper and lower direction. The two sets of traction rollers rotate in opposite directions relative to each other. The traction rollers are driven to rotate by a servo motor. When the two sets of traction rollers press and clamp the coating film, they rotate in opposite directions relative to each other to move the coating film. Each set of traction rollers includes:

[0070] A first horizontal rotating shaft 6 is rotatably mounted on the workbench 1 via a bearing and driven to rotate by a corresponding servo motor;

[0071] a cylindrical rotating body 7, which is coaxially sleeved on the first horizontal rotating shaft 6 and rotates along with the first horizontal rotating shaft 6;

[0072] and elastic pressing mechanisms, which are multiple groups provided on the cylindrical rotating body 7 and evenly distributed along the circumference of the cylindrical rotating body 7;

[0073] The covering film and the covering film on which the wood and bamboo materials are placed are compressed between two corresponding sets of elastic compression mechanisms in two symmetrical sets of traction rollers. When the two sets of traction rollers rotate, the covering film and the covering film on which the wood and bamboo materials are placed are pulled and moved. During the entire process, the covering film and the covering film on which the wood and bamboo materials are placed are always compressed under the elastic thrust of the elastic compression mechanism. In a preferred embodiment, a support mechanism such as a support table or multiple sets of support rollers arranged in parallel can be provided for the lower layer of the covering film to facilitate its support of the wood and bamboo materials. In addition, when the traction mechanism provides traction to the covering film, in order to keep the covering film straightened, a corresponding tension maintaining mechanism should be provided in the unwinding structure of the upper and lower double-layer unwinding mechanism and controlled by a corresponding control system, such as a tensioning pulley for tensioning the belt. The tensioning pulley is common knowledge well known to technical personnel in this field and will not be described in detail here.

[0074] Furthermore, the elastic pressing mechanism includes:

[0075] A guide cylindrical groove 8 is radially provided on the circumferential surface of the cylindrical rotating body 7. A sliding support rod 9 is coaxially provided in the guide cylindrical groove 8. The sliding support rod 9 slides in the guide cylindrical groove 8. A first compression spring 10 is connected between the end of the sliding support rod 9 that extends into the guide cylindrical groove 8 and the bottom surface of the guide cylindrical groove 8.

[0076] And the arc-shaped pressure plate 11, the middle position of its inner arc surface is hingedly connected to the sliding support rod 9 and one end extends out of the guide cylindrical groove 8, and both ends of the inner arc surface of the arc-shaped pressure plate 11 are provided with a first tension spring 12 connected to the sliding support rod 9.

[0077] When the first spring 11 is in the state of being compressed, the first spring 11 is pressed against the second spring 11 and the second spring 11 is in the state of being compressed.

[0078] Furthermore, the feeding mechanism includes a conveyor belt 13, which is arranged on the workbench 1 and is used to uniformly feed the wood and bamboo materials between the upper and lower layers of the coating film unwound by the upper and lower double-layer unwinding mechanisms. A guide plate 14 is provided between the conveyor belt 13 and the coating film supported by the lower guide roller 3 to guide the wood and bamboo materials onto the horizontal coating film. In other words, the conveying end of the conveyor belt 13 conveys the wood and bamboo materials to a position between the two layers of coating film. With the auxiliary guidance of the guide plate 14, the wood and bamboo materials are fed to the lower layer of coating film and moved by the coating film. The conveyor belt 13 is a conventional electric conveyor belt in the prior art and can be controlled by a controller or control system. The conveyor belt 13 is used to feed the wood and bamboo materials at a uniform speed and accurately, avoiding manual placement or damage to the coating film, and also saving manpower.

[0079] Furthermore, the edge sealing mechanism includes a transverse edge sealing mechanism and a longitudinal edge sealing mechanism, and the double-layer covering film around the wood and bamboo materials is edge-sealed by the transverse edge sealing mechanism and the longitudinal edge sealing mechanism;

[0080] Among them, in the traveling direction of the covering film, the longitudinal edge sealing mechanism is composed of two groups with the same structure and symmetrically distributed on both sides of the traveling direction of the covering film. In this traveling direction, the two side edges perpendicular to this direction are first heat-sealed by the transverse edge sealing mechanism, and then the other two edges are heat-sealed by the subsequent two groups of longitudinal edge sealing mechanisms. Finally, the heat sealing treatment of the four edges of the wood and bamboo materials is completed to complete the sealed packaging of the wood and bamboo materials.

[0081] Furthermore, the transverse edge sealing mechanism includes:

[0082] The first heating tube 15 is a horizontally arranged long straight tubular structure. The first heating tube 15 is arranged parallel to the workbench 1 and the axis extension direction of the first heating tube 15 is perpendicular to the direction of travel of the coating film. The first heating tube 15 is provided with a first electric heating resistance wire 16;

[0083] And a second horizontal rotating shaft 17, which is rotatably set on the workbench 1 through a bearing and is driven to rotate by a servo motor. Two groups of swing arms 18 are symmetrically provided at both ends of the second horizontal rotating shaft 17. The two groups of swing arms 18 are symmetrically distributed at both ends of the first heating tube 15. The swing arms 18 are rotatably connected to the ends of the first heating tube 15 through bearings. A second tension spring 19 is connected between the swing arms 18 and the first heating tube 15.

[0084] Specifically, during operation, a corresponding servo motor drives the second horizontal rotating shaft 17 to rotate, thereby driving the first heating tube 15 to swing through a swing arm 18. The first heating tube 15 and the swing arm 18 are rotatably connected. During the movement of the film and wood, the length or height of the swing arm 18, as well as its swing speed, are controlled based on the spacing between the wood and the speed of the film. As the wood moves below the first heating tube 15, the swing arm 18 raises the first heating tube 15, allowing the wood to pass through, then lowers it until it presses against the two layers of film, and then instantly raises it again to allow the next wood to pass through, repeating the heat sealing process. During this process, the heating of the first heating wire 16 brings the first heating tube 15 to a temperature sufficient to heat-seal the two layers of film. Because the film is constantly moving, the first heating tube 15 and the swing arm 18 can rotate relative to each other, allowing the first heating tube 15 to press against the film and rotate synchronously with the film's movement, thereby ensuring that the film does not interfere with its normal movement.

[0085] Furthermore, the edge sealing mechanism further includes a third horizontal rotating shaft 20 supporting the two sets of longitudinal edge sealing mechanisms so that the two sets of longitudinal edge sealing mechanisms rotate synchronously under the drive of the servo motor. The longitudinal edge sealing mechanism includes:

[0086] The second heating tube 21 is a circular tube structure, and a second electric heating resistance wire 22 is provided in the second heating tube 21;

[0087] The second heating tubes 21 are connected to the third horizontal rotating shaft 20 via multiple sets of fixed struts 23. Specifically, the heating of the second heating resistor 22 causes the second heating tubes 21 to reach a temperature sufficient to heat-seal the two layers of film. During operation, the second heating tubes 21 roll along with the advancing film, with two sets of second heating tubes 21 positioned at either end of the wood or bamboo material, heat-sealing the other two sides of the film.

[0088] A method for treating wood and bamboo materials with mildew-proofing adopts the above-mentioned device for treating wood and bamboo materials with mildew-proofing, and comprises the following steps:

[0089] Step 1: Take out the wood and bamboo materials that have been sterilized and set aside;

[0090] Step 2: Prepare the wrapping film for sealing the wood and bamboo materials at the upper and lower double-layer unwinding mechanisms, and use the traction mechanism to continuously pull the upper and lower layers of the wrapping film to unwind synchronously;

[0091] Step 3: Place the prepared wood and bamboo materials one by one along the width direction of the conveyor belt 13 of the feeding mechanism, and control the spacing between the wood and bamboo materials so that the wood and bamboo materials are evenly fed into the space between the upper and lower layers of the synchronously unwound covering film through the conveyor belt 13 so that the wood and bamboo materials move forward with the covering film;

[0092] Step 4. In the traveling direction of the covering film and the wood and bamboo materials, the upper and lower layers of the covering film between each two adjacent wood and bamboo materials are first heat-sealed by the transverse edge sealing mechanism in the edge sealing mechanism, and then the upper and lower layers of the covering film at the two end positions of the wood and bamboo materials are heat-sealed by the longitudinal edge sealing mechanism, so as to finally complete the heat-sealing treatment of the upper and lower layers of the covering film around the wood and bamboo materials, thereby realizing the sealed wrapping of the wood and bamboo materials.

[0093] In another embodiment of a method and device for treating wood and bamboo materials with mildew resistance provided by the present invention, see Figure 1 、 10 As shown in Figures 1 and 11, the device further comprises a splitting mechanism disposed on the workbench 1 at the end position in the direction of travel of the coating film, and the coating film moved to the traction mechanism station is split by the splitting mechanism. The splitting mechanism comprises a cylindrical tool holder 24 disposed on the workbench 1 at the end position in the direction of travel of the coating film. The cylindrical tool holder 24 is horizontally disposed on the workbench 1 and supported by a bracket so as to be rotated by a servo motor.

[0094] Two sets of cutting knives 25 are symmetrically arranged on both sides of the circumference of the cylindrical knife holder 24, and the cutting knives 25 are connected to the cylindrical knife holder 24 through an elastic reset mechanism;

[0095] The elastic reset mechanism includes:

[0096] A blade receiving groove 26 is provided on the circumferential surface of the cylindrical tool holder 24 to receive the cutting blade 25. The cutting blade 25 slides in the blade receiving groove 26.

[0097] a second compression spring 27 disposed in the blade receiving slot 26 and connected between the bottom surface of the blade receiving slot 26 and the cutting blade 25;

[0098] And a limiting slide groove 28 is opened on the inner surface of the blade accommodating groove 26 , and a limiting slider 29 is provided at the end of the cutting knife 25 extending into the blade accommodating groove 26 , and the limiting slider 29 slides in the limiting slide groove 28 .

[0099] Specifically, during operation of the slicing mechanism, a cylindrical blade holder 24, supported by a rotatable support, is driven by a servo motor to rotate, thereby driving the cutting blade 25. The length and rotational speed of the cutting blade 25 are designed to correspond to the travel speed of the coating film. Consequently, each time the cutting blade 25 rotates perpendicular to the worktable 1, its blade is positioned between two adjacent wood or bamboo materials, severing the heat-sealed portion between the two materials and completing the slicing of the coated wood or bamboo materials for subsequent storage. More specifically, a limiting slider 29 slides within a limiting slot 28, limiting the length of the cutting blade 25 within the blade receiving slot 26. As the cutting blade 25 rotates perpendicular to the worktable 1, it compresses a second compression spring 27 until the cutting blade 25 is fully compressed, at which point the spring's rebound force propels the cutting blade 25 through the coating film, completing the slicing operation.

[0100] In another embodiment, in order to further improve the strength and accuracy of the cutting knife 25 in cutting the coating film and avoid the situation where the coating film cannot be cut due to insufficient elasticity, the elastic reset mechanism in this embodiment can be replaced by an active cutting drive mechanism, which is used to drive the cutting knife 25 to cut the coating film through the active cutting drive mechanism when the cutting knife 25 rotates to a state perpendicular to the workbench 1.

[0101] Furthermore, the active cutting drive mechanism includes a blade receiving groove 26, a limiting slide groove 28 and a limiting slider 29 in the elastic reset mechanism, wherein a third compression spring 30 is provided between the limiting slider 29 and the limiting slide groove 28 for pushing the limiting slider 29 to slide so as to push the cutting knife 25 to move in the direction of extending out of the blade receiving groove 26. The mechanism also includes a contact switch and a telescopic cylinder 31. The cylindrical knife holder 24 is internally provided with a receiving groove 32 connected to the blade receiving groove 26 for mounting the telescopic cylinder 31. The telescopic end of the telescopic cylinder 31 points to the cutting knife 25 extending into the blade receiving groove 26.

[0102] Furthermore, the contact switch includes a strip avoidance groove 33, which is opened on the inner wall of the blade accommodating groove 26 and is arranged opposite to the limiting slide groove 28. A proximity switch 34 is provided in the strip avoidance groove 33, and a metal block 35 is provided on the cutting knife 25 to slide in the strip avoidance groove 33 to correspond to the proximity switch 34 sensing the moving position of the metal block 35 and the cutting knife 25.

[0103] Specifically, the electrical connections and control of all electrical components in this embodiment can be programmed and controlled via a controller or PLC control system, and are common knowledge known to those skilled in the art, and will not be further elaborated upon here. As the cutting blade 25 rotates, the compression limit slider 29 compresses the third compression spring 30, while the metal block 35 moves toward contact with the proximity switch 34. When the cutting blade 25 rotates to a position perpendicular to the workbench 1, the metal block 35 contacts the proximity switch 34, causing the telescopic cylinder 31 to receive the signal and react, using the cylinder's thrust to propel the cutting blade 25 toward the direction of extending out of the blade receiving slot 26 and severing the coating.

[0104] In another embodiment of a method and device for treating wood and bamboo materials with mildew resistance provided by the present invention, see Figure 1 As shown, in order to more conveniently enable the conveyor belt 13 of the feeding mechanism to transport wood and bamboo materials at equal intervals, an interval positioning mechanism is provided on the conveyor belt 13;

[0105] Furthermore, the spacing positioning mechanism includes a plurality of limiting strips 36 distributed at equal intervals on the conveyor belt 13. The plurality of limiting strips 36 distributed at equal intervals serve as markers, making it easy to place wood and bamboo materials on the conveyor belt 13 at equal intervals. At the same time, during the process of conveying the wood and bamboo materials on the conveyor belt 13, the limiting strips 36 limit the wood and bamboo materials to prevent them from shifting and affecting the effect of equal-interval loading.

[0106] Furthermore, in order to more stably convey the wood and bamboo materials from the conveyor belt 13 to the coating film unwound on the lower unwinding mechanism, a pushing mechanism is provided above the conveyor belt 13 and at the intersection of the conveyor belt 13 and the coating film to assist in pushing the wood and bamboo materials onto the coating film unwound on the lower unwinding mechanism;

[0107] Furthermore, the pushing mechanism includes a fourth horizontal rotating shaft 37 and auxiliary push plates 38 evenly distributed around the circumference and connected to the fourth horizontal rotating shaft 37. The fourth horizontal rotating shaft 37 is driven by a servo motor. The auxiliary push plates 38 are regulated to match the speed of the wood and bamboo materials being conveyed by the conveyor belt 13, so that the auxiliary push plates 38 can accurately push the wood and bamboo materials one by one onto the guide plate 14, and ultimately enable the wood and bamboo materials to pass over the guide plate 14 and contact the moving coating film, so that the wood and bamboo materials are successfully moved along with the coating film.

[0108] In another embodiment of a method and device for treating wood and bamboo materials with mildew resistance provided by the present invention, see Figure 1 、 3As shown, in order to satisfy the requirements of not only compressing the two layers of coating film but also compressing the two layers of coating film wrapped around the wood and bamboo materials, the elastic pressing mechanism in the traction mechanism is in the form of circumferentially uniformly distributed and tightly arranged. In order to further improve the continuity of the elastic pressing mechanism and thus enhance the stability of the clamped coating film, in this embodiment, the elastic pressing mechanism includes an elastic support body and an anti-slip belt 39. The elastic support body is a plurality of groups provided on the cylindrical rotating body 7 and is circumferentially uniformly distributed along the circumferential surface of the cylindrical rotating body 7. The anti-slip belt 39 is sleeved on the outside of the plurality of groups of elastic support bodies.

[0109] Furthermore, the elastic support body includes a sliding support rod 9, a guide cylindrical groove 8, a first compression spring 10 and an arc-shaped pressure plate 11 in the elastic pressing mechanism, wherein the sliding support rods 9 in the elastic support body in this embodiment are distributed more in number and more densely, and the corresponding arc-shaped pressure plate 11 is shorter in length, so that its swing will not affect the pressing force on the coating film.

[0110] Furthermore, the anti-slip belt 39 is sleeved on the outer side of the arc-shaped pressure plate 11 which is evenly distributed in the circumferential direction, so that the anti-slip belt 39 contacts the coating film and presses the coating film. The elasticity and anti-slip properties of the anti-slip belt 39 itself are utilized to better tighten the belt, and the sliding support rod 9 is retracted in the guide cylindrical groove 8 to compress the rebound force of the first compression spring 10, which can also act on the coating film and the coating film covered with wood and bamboo materials through the anti-slip belt 39, and then the anti-slip belt 39 can better continuously pull the coating film to move.

[0111] In another embodiment of a method and device for treating wood and bamboo materials with mildew resistance provided by the present invention, see Figure 1 、 7 As shown in Figures 8 and 9, in the edge sealing mechanism, the transverse edge sealing mechanism includes factors such as the spacing between two adjacent wood and bamboo materials and the moving speed in order to better match the rhythm of evenly spaced feeding. In this embodiment, two groups of first heating tubes 15 with first electric heating resistance wires 16 are symmetrically arranged on both sides of the second horizontal rotating shaft 17 in the transverse edge sealing mechanism, and the first heating tubes 15 and the second horizontal rotating shaft 17 are connected by a telescopic support mechanism to match the change in the spacing between the first heating tubes 15 and the second horizontal rotating shaft 17 when the second horizontal rotating shaft 17 drives the first heating tubes 15 to rotate and after the first heating tubes 15 contact the workbench 1, and the first heating tubes 15 can always be pressed against the covering film above the workbench 1 to perform edge sealing processing through elastic thrust;

[0112] Furthermore, the telescopic support mechanism includes a support tube 40 and an inner support rod 41. The inner support rod 41 is coaxially disposed within the support tube 40 and slides therein. A fourth compression spring 42 is connected to the inner support rod 41 within the support tube 40, so that when the inner support rod 41 swings perpendicular to the surface of the workbench 1, the elasticity of the fourth compression spring 42 pushes the first heating tube 15 against the heat-sealed portion of the coating film to perform heat sealing. Furthermore, as the coating film advances, the two symmetrical groups of first heating tubes 15 rotate accordingly, alternately heat-sealing the coating film between adjacent wood and bamboo materials based on factors such as the spacing between the adjacent wood and bamboo materials and the movement speed.

[0113] In another embodiment, the cross-section of the first heating tube 15 is conical, and the pointed end faces in the opposite direction to the second horizontal rotation axis 17. The coating film is then heat-sealed on the side where the pointed end of the first heating tube 15 is located, thereby shortening the heat-sealing width and being able to cope with the heat-sealing treatment of the coating film between wood and bamboo materials with smaller spacing. Therefore, when designing the heating resistance wire in the first heating tube 15, it is considered to position the heating resistance wire close to the side where the pointed end of the first heating tube 15 is located, so that this position is the focus of heating, thereby achieving more precise heating and heat sealing.

[0114] Among them, the electrical connection of the electric heating resistance wire in the heating tube in this device and its control (including temperature control by temperature sensor, etc.) are common knowledge known to technical personnel in this field. For details, please refer to the structural principle of the hot air blower. This device utilizes the structural principle of the hot air blower, but its specific usage method is different from the existing technology, which will not be repeated here.

[0115] In another embodiment of the feeding mechanism of the wood and bamboo material anti-mildew treatment method and treatment device provided by the present invention, see Figure 1 、 12 As shown in 13, if the wood and bamboo materials transported by the above-mentioned feeding mechanism are nearly cylindrical, the rolling of the wood and bamboo materials cannot be avoided, which will affect the equal-spaced feeding of the wood and bamboo materials and the subsequent equal-spaced heat-sealing and edge-sealing processes. In order to solve this problem and the subsequent continuity problem, in this embodiment, the feeding mechanism also includes an anti-rolling strip 43 pasted on the side of the wood and bamboo materials. The anti-rolling strip 43 is detachably pasted on the side of the wood and bamboo materials to limit the rolling of the wood and bamboo materials and prevent them from rolling. After being placed on the conveyor belt 13, the anti-rolling strip 43 can also be pressed against the limit strip 36 to limit the position so that the wood and bamboo materials are transported at equal intervals. The pasting material can be made of double-sided tape or dispensing glue, which can be easily separated by direct pulling, and the process of pasting the anti-rolling strip 43 on the side of the wood and bamboo materials can be completed before using this device. In order to realize the subsequent processes, the length of the anti-rolling strip 43 is longer than the length of the wood and bamboo materials, and both ends of the anti-rolling strip 43 are longer than the ends of the wood and bamboo materials.

[0116] Furthermore, in order to better prevent the cylindrical wood and bamboo materials from rolling, the upper and lower layers of the covering film can be arranged slightly tilted, or the front end of the covering film located at the lower layer can be slightly tilted, for example, with an inclination angle of only 1-3 degrees, so that the wood and bamboo materials that have been fed into the position can reach the covering film located at the lower layer in the form of climbing a slope. The anti-roll bar 43 can be combined to prevent the wood and bamboo materials from rolling, and the table top of the workbench 1 can also be correspondingly arranged according to the inclination of the covering film. Therefore, the anti-roll bar 43 and the tilted covering film can ensure that the wood and bamboo materials are arranged at equal intervals and will not move.

[0117] Based on the above-mentioned feeding mechanism, in another embodiment of a method and device for treating wood and bamboo materials with mildew resistance provided by the present invention, see Figure 1 、 12 As shown in Figures 13 and 14, before the wood and bamboo materials with anti-rolling strips 43 enter the wrapping film heat sealing process during movement, the anti-rolling strips 43 need to be removed to seal the wood and bamboo materials separately. Therefore, in this embodiment, correspondingly, in another embodiment of the transverse edge sealing mechanism, it includes a roller 44, and also includes the above-mentioned first heating tube 15, first electric heating resistance wire 16, second horizontal rotating shaft 17, swing arm 18 and second tension spring 19. The swing arm 18 is supported by the second horizontal rotating shaft 17 and the roller 44 to swing, so as to drive the roller 44 to swing, and the roller 44 and the swing arm 18 are rotatably connected. Therefore, by connecting the second tension spring 19, the roller 44 is rotated and then reset. The second horizontal rotating shaft 17 is driven to rotate by a servo motor or a stepping motor until the roller 44 moves in a direction away from the workbench 1. Therefore, a torsion spring can be set between the second horizontal rotating shaft 17 and the swing arm 18. After the stepping motor is powered off, the rebound force of the torsion spring can drive the swing arm 18 to reset and swing, so as to drive the roller 44 to be pressed against the surface of the workbench 1, and then the roller 44 is pressed against the covering film to perform heat sealing;

[0118] Furthermore, in this embodiment, the first heating tube 15 is a strip-shaped protruding structure connected along the axial direction of the roller 44, and the first electric heating resistance wire 16 is pre-buried in the first heating tube 15 to perform heating, thereby allowing the first heating tube 15 to reach the temperature of the heat-sealing coating film and heat-seal the coating film when it contacts the coating film;

[0119] Furthermore, in this embodiment, a reset turntable 45 and an arc-shaped separation push rod 46 are further included. The reset turntable 45 is rotatably connected to the swing arm 18 on the side opposite to the roller 44, that is, a reset turntable 45 is provided on the upper end swing arm 18 of the two end sides of the roller 44, and an arc-shaped separation push rod 46 is connected to the circumferential surface of each reset turntable 45 to correspond to the two ends of the anti-roll bar 43 being longer than the wood and bamboo material. At the same time, the distance between the reset turntable 45 and the arc-shaped separation push rod 46 at the two end positions also needs to be greater than the width of the covering film covering the wood and bamboo material. An arc-shaped guide groove 47 is provided on the upper edge of the reset turntable 45, and a limiting rod 48 is provided on the swing arm 18 to extend into the arc-shaped guide groove 47 and slide in the arc-shaped guide groove 47. A fifth compression spring 49 is connected between the limiting rod 48 and the inner side of the arc-shaped guide groove 47.

[0120] Specifically, during the heat sealing process, the roller 44 swings downward, so that the roller 44 contacts or presses on the wood and bamboo material, and the arc-shaped separation push rod 46 also contacts the table surface of the workbench 1, and even abuts on the anti-rolling strip 43. As the roller 44 continues to swing downward, and the wood and bamboo material continues to move forward with the covering film, since the diameter of the roller 44 is set to be larger than the diameter of the wood and bamboo material, the wood and bamboo material moving with the covering film contacts the roller 44, causing the roller 44 to roll synchronously with its movement and roll over the wood and bamboo material at the same time, but the arc-shaped separation push rod continues to abut on the anti-rolling strip 43, thereby causing the wood and bamboo material to be separated from the anti-rolling strip 43. The anti-roll bar 43 is separated from the roller 44, and the anti-roll bar 43 is promptly withdrawn to prevent it from affecting the subsequent heat-sealing process. During this process, the arc-shaped separation push rod 46 swings upward to prevent it from affecting the downward swing of the roller 44. When the fifth compression spring 49 is compressed, the limit rod 48 moves to the end position of the arc-shaped guide groove 47, preventing the return turntable 45 and the arc-shaped separation push rod 46 from further rotation. The limit rod 48 also acts in the same way on its return stroke to limit the rotation angle of the arc-shaped separation push rod 46. At the same time, the roller 44 rolls until the first heating tube 15 is pressed against the two layers of film below, which are free of wood or bamboo material, to perform the heat-sealing process. Immediately thereafter, the second horizontal rotating shaft 17 and the swing arm 18 are driven by a stepper motor to rotate the roller 44 upward to clear the film above the workbench 1. Simultaneously, the roller 44 loses its external force, and driven by the elastic force of the second tension spring 19, the first heating tube 15 rotates upward, that is, in the direction opposite to the film, to enable the above-mentioned process to continue.

[0121] Furthermore, in order to enable the roller 44 to make a timely reset movement in a short time after the first heating tube 15 rotates to press on the two layers of covering film without wood or bamboo materials below for heat sealing treatment, a pressure sensor can be provided on the first heating tube 15 to sense the pressure change of the first heating tube 15 pressing on the covering film, etc., so that the roller 44 can make a reset swing response in time.

[0122] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
