Description

Technical Field

[0001] This invention relates to the field of edge banding technology for pallet boxes, and more particularly to an edge banding machine adapted to pallet boxes of different sizes. Background Technology

[0002] In the wood products processing industry, pallet boxes are an important type of packaging container, and the production process of them has strict requirements for the quality of the edge banding of the boards.

[0003] Traditional edge banding machines have significant technical limitations when processing box panels of different sizes: Poor size adaptability: Conventional edge banding machines use fixed-space limit devices, which cannot effectively adapt to wood boards of different widths. This causes small-sized boards to easily shift left and right when edge banding, while large-sized boards may exceed the processing range of the equipment.

[0004] Insufficient conveying stability: Existing technologies mostly use a conveying method with tracks on both sides. This design may cause the boards to warp and deform when heated during the edge sealing process, directly affecting the conveying position of the boards. Summary of the Invention

[0005] This invention discloses an edge-sealing machine adaptable to boxes of different sizes, aiming to solve the technical problems of poor size adaptability and insufficient conveying stability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An edge-sealing machine adaptable to different sized panel boxes includes two symmetrically arranged side frames, and further includes: two sets of conveyor track wheels respectively mounted on the two side frames; two edge-sealing components respectively mounted on the outer side of the two side frames; multiple sliders respectively fixedly mounted on the bottom outer wall of the two side frames; a bidirectional electric slide rail, with the multiple sliders divided into two sets symmetrically and movably connected to the bidirectional electric slide rail; a central conveying mechanism disposed between the two side frames; a linkage mechanism mounted on the top of the central conveying mechanism; and two sets of grinding mechanisms and limiting mechanisms mounted on the outer side of the two side frames. The central conveying mechanism includes: two base plates, which are fixedly connected to the inner walls of opposite sides of two side frames, and the top of the base plates is at the same height as the top of the conveyor track wheel assembly located below; two outer frames, whose bottom inner walls are movably engaged with roller brackets, and whose inner walls are equidistantly connected with multiple rollers; and multiple pneumatic rods, which are fixedly connected to the outer walls of each outer frame and are used to drive the roller brackets to move within the outer frames. Each of the rollers includes: a roller body with a rubber sleeve fixedly fitted around its outer periphery; a rotating shaft fixedly connected to both ends of the roller body, and multiple roller bodies are rotatably connected to the roller bracket through the rotating shafts, with one end of multiple rotating shafts in the same group simultaneously connected to a drive assembly two; Each of the limiting mechanisms includes: a support frame three, fixedly connected to one outer wall of the side frame; a movable frame, movably sleeved on the outer periphery of the support frame three; a side limiting plate, fixedly connected to the top outer wall of the movable frame; multiple limiting holes two, which are disposed through the movable frame and the support frame three; and multiple bolts two, which are respectively engaged in the multiple limiting holes two. The central conveying mechanism further includes: multiple square through slots, which are respectively installed through the inner walls of the two outer frames; multiple slide plates, which are respectively fixedly connected to the outer walls of the two roller brackets, and the multiple slide plates are respectively movably engaged in the multiple square through slots; and the output ends of the multiple air rods are respectively fixedly connected to the top of the multiple slide plates.

[0007] By incorporating a central conveying mechanism, when conveying and edge-sealing wooden boards, both ends are centered and positioned by side limiting plates in the contact limiting mechanism. Multiple rollers located above then descend under the extension of the pneumatic strut's output end, pressing against the surface of the wooden board. Together with the bottom plate, they clamp and convey the board, and the rubber sleeve further enhances the stable pressure on the top of the board, preventing displacement. Compared to existing technologies, this structure replaces side-side pressure conveying with central pressure conveying. The side tracked wheel sets prevent edge warping and compensate for the insufficient stability of a single support, ensuring effective edge sealing. Furthermore, this structure allows for the translation of the side conveyor tracked wheel sets via bidirectional electric slide rails, and with the central conveying limiting structure, it can accommodate different sizes of pallet boxes.

[0008] In a preferred embodiment, each of the grinding mechanisms includes: a second support frame, fixedly connected to one outer wall of the side frame; a base frame, movably snapped onto the outer wall of the second support frame; and multiple first limiting holes, simultaneously penetrating the inner walls of the second support frame and the base frame. Each of the grinding mechanisms further includes: a plurality of bolts, which are movably engaged in a corresponding limiting hole; a bearing bracket, which is fixedly connected to the top of the base frame; a plurality of grinding wheels, which are simultaneously rotatably connected to the bearing bracket, and the grit number of the plurality of grinding wheels is arranged in ascending order from front to back; and a drive assembly, which is mounted on the bearing bracket and is used to drive the plurality of grinding wheels to rotate simultaneously. Each of the aforementioned polishing mechanisms further includes: a square dust collection chamber, fixedly embedded in the inner wall of the bearing bracket; multiple micro scrapers, fixedly connected to the groove of the square dust collection chamber; and a connecting hose, fixedly connected to one side of the inner wall of the square dust collection chamber, with a vacuum cleaner fixedly installed at one end of the connecting hose.

[0009] With a sanding mechanism, the sides of the wooden board will come into contact with multiple sanding wheels during the horizontal movement of the board, achieving coarse sanding followed by fine sanding, ensuring the smoothness of the board surface. After sanding, multiple micro scrapers simultaneously contact the sanded area, scraping off or loosening the wood chips generated and adhering during the sanding process, thus completing the thorough cleaning of wood chips and further ensuring the subsequent edge banding effect.

[0010] In a preferred embodiment, the linkage mechanism includes: two sets of cross linkages, each end of which is hinged to the top of two side frames, and the tops of two outer frames are respectively hinged to the intersection of the two sets of cross linkages; two T-shaped support plates, which are respectively fixedly connected to the top outer walls of the two outer frames, and each T-shaped support plate has multiple protruding strips fixedly connected to its top. The linkage mechanism further includes: a support frame 1, which is fixedly connected to the top outer wall of the bidirectional electric slide rail; and two waist-shaped grooves, which are symmetrically arranged through the top inner wall of the support frame 1. The linkage mechanism further includes: multiple pneumatic rods, which are simultaneously fixedly connected to the top outer wall of the support frame; and a U-shaped pressure plate, whose bottom outer wall is simultaneously fixedly connected to the output ends of the multiple pneumatic rods.

[0011] With the linkage mechanism in place, as the outer frames on both sides move inward or outward simultaneously, the outer frame in the middle position also moves inward or outward at equal intervals, thus ensuring the stability of the wooden board under force when multiple rollers press down. In addition, after the translation is completed, the U-shaped pressure plate is pressed down on the T-shaped support plate by the air rod, which can provide compression limit for the roller position and prevent the roller from shifting during the conveying of the wooden board, thus affecting the stability of the wooden board conveying.

[0012] As can be seen from the above, the present invention has the technical effect of being adaptable to the use of wooden boards of different sizes, ensuring the stability of wooden board transportation, and ensuring the edge sealing effect. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0021] The edge banding machine disclosed in this invention is adapted to different sizes of pallet boxes and is mainly used in the edge banding of wooden pallet boxes.

[0022] Reference Figures 1-5 An edge-sealing machine adaptable to different sized panel boxes includes two symmetrically arranged side frames 3, two sets of conveyor track wheel sets 7, two edge-sealing components 8, multiple sliders 6, a bidirectional electric slide rail 5, a central conveying mechanism 2, a linkage mechanism 1, two sets of grinding mechanisms 4, and a limiting mechanism 9. The two sets of conveyor track wheel sets 7 are respectively installed on the two side frames 3; the two edge-sealing components 8 are respectively installed on the outer side of the two side frames 3; the multiple sliders 6 are respectively fixedly installed on the bottom outer wall of the two side frames 3; the multiple sliders 6 are divided into two groups and symmetrically movably connected to the bidirectional electric slide rail 5; the central conveying mechanism 2 is arranged between the two side frames 3; the linkage mechanism 1 is installed at the top of the central conveying mechanism 2; and the two sets of grinding mechanisms 4 and the limiting mechanism 9 are installed on the outer side of the two side frames 3. The central conveying mechanism 2 includes: two base plates 209, two outer frames 201, and multiple pneumatic rods 205. The two base plates 209 are respectively fixedly connected to the inner walls of opposite sides of the two side frames 3, and the top of the base plates 209 is at the same height as the top of the conveyor track wheel set 7 located below. Roller brackets 203 are movably engaged with the inner walls of the bottom ends of the two outer frames 201, and multiple rollers are equidistantly rotatably connected to the inner walls of the roller brackets 203. Multiple pneumatic rods 205 are respectively fixedly connected to the outer walls of each outer frame 201, and are used to drive the roller brackets 203 to move within the outer frame 201. Each roller includes: a roller body 206 and a rotating shaft 208. A rubber sleeve 207 is fixedly sleeved on the outer periphery of the roller body 206. The rotating shaft 208 is fixedly connected to both ends of the roller body 206, and multiple roller bodies 206 are rotatably connected to the roller bracket 203 through the rotating shaft 208. One end of multiple rotating shafts 208 in the same group is simultaneously connected to a second drive assembly. Each limiting mechanism 9 includes: a support frame 3 903, a movable frame 902, a side limiting plate 901, multiple limiting holes 2 904, and multiple bolts 2 905. The support frame 3 903 is fixedly connected to one side outer wall of the side frame 3; the movable frame 902 is movably sleeved on the outer periphery of the support frame 3 903; the side limiting plate 901 is fixedly connected to the top outer wall of the movable frame 902; multiple limiting holes 2 904 are provided through the movable frame 902 and the support frame 3 903; and multiple bolts 2 905 are respectively engaged in the multiple limiting holes 2 904.

[0023] When conveying and edge-sealing wooden boards, their two ends are centered by contacting the side limiting plates 901 in the limiting mechanism 9, and the conveyor track wheel set 7 slightly clamps their upper and lower sides. The limiting mechanism 9 uses corresponding limiting holes 904 at different positions and the engagement of bolts 905 to change the position of the side limiting plates 901 to accommodate wooden boards of different widths. Then, multiple rollers located above descend under the extension of the output end of the pneumatic strut 205 and press against the surface of the wooden board, forming a seal. The bottom plate 209 clamps and conveys the wooden board, and the rubber sleeve 207 increases the stable compression on the top of the wooden board to prevent the board from shifting. In this structure, compared with the existing technology, the central compression conveying replaces the two-sided compression conveying. The two-sided track wheel sets 7 can play the role of preventing edge warping, while making up for the problem of insufficient stability of a single support and ensuring the edge sealing effect. In addition, the two-way electric slide rail 5 can drive the two-sided conveying track wheel sets 7 to move horizontally. With the addition of the central conveying limiting structure, it can be adapted to the use of cofferdam boxes of different sizes.

[0024] Reference Figure 4In a preferred embodiment, the central conveying mechanism 2 further includes: a plurality of square through slots 202, which are respectively disposed through the inner walls of the two outer frames 201 on multiple sides; a plurality of slide plates 204, which are respectively fixedly connected to the outer walls of the two roller brackets 203, and the plurality of slide plates 204 are respectively movably engaged in the plurality of square through slots 202; and the output ends of the plurality of air rods 205 are respectively fixedly connected to the top of the plurality of slide plates 204.

[0025] Reference Figure 4 In a preferred embodiment, the linkage mechanism 1 includes: two sets of cross linkages 105, the two ends of which are respectively hinged to the top ends of the two side frames 3, and the top ends of the two outer frames 201 are respectively hinged to the intersection of the two sets of cross linkages 105; two T-shaped support plates 106, which are respectively fixedly connected to the top outer walls of the two outer frames 201, and each T-shaped support plate 106 has a plurality of protrusions 107 fixedly connected to its top end.

[0026] The linkage mechanism 1 also includes: a support frame 104, which is fixedly connected to the top outer wall of the bidirectional electric slide rail 5; and two waist-shaped grooves 102, which are symmetrically arranged through the top inner wall of the support frame 104.

[0027] The linkage mechanism 1 also includes: multiple air rods 103, which are fixedly connected to the top outer wall of the support frame 104; and a U-shaped pressure plate 101, whose bottom outer wall is fixedly connected to the output end of the multiple air rods 103.

[0028] The linkage mechanism 1 is used to limit the position of the two sets of outer frames 201. As the outer frames 201 on both sides move inward or outward at the same time, the outer frame 201 in the middle position also moves inward or outward at equal distances, thereby ensuring the stability of the wooden board under force when multiple rollers press down. In addition, based on the structure of the T-shaped support plate 106 moving in the waist groove 102, the stability of the two outer frames 201 during the translation process can be ensured. After the translation is completed, the U-shaped pressure plate 101 is driven to press down on the T-shaped support plate 106 by the air rod 103. Under the action of the protrusion 107, the T-shaped support plate 106 cannot move after pressing down, thereby providing a squeezing limit for the position of the rollers and preventing the rollers from shifting when conveying the wooden board, which affects the stability of the wooden board conveying.

[0029] Reference Figure 6 In a preferred embodiment, each grinding mechanism 4 includes: a second support frame 409, which is fixedly connected to one side outer wall of the side frame 3; a base frame 408, which is movably snapped onto the outer wall of the second support frame 409; and a plurality of limiting holes 410, which are simultaneously disposed through the inner walls of the second support frame 409 and the base frame 408.

[0030] Each grinding mechanism 4 also includes: multiple bolts 411, which are movably engaged in corresponding limiting holes 410; a bearing bracket 403, which is fixedly connected to the top of the base frame 408; multiple grinding wheels 407, which are rotatably connected to the bearing bracket 403, and the grit number of the multiple grinding wheels 407 is arranged in ascending order from front to back; and a drive assembly 404, which is mounted on the bearing bracket 403 and is used to drive the multiple grinding wheels 407 to rotate simultaneously.

[0031] Each polishing mechanism 4 also includes: a square dust collection chamber 405, which is fixedly embedded in the inner wall of the bearing bracket 403; multiple micro scrapers 406, which are fixedly connected to the groove of the square dust collection chamber 405; and a connecting hose 402, which is fixedly connected to one side of the inner wall of the square dust collection chamber 405, and a vacuum cleaner 401 is fixedly installed at one end of the connecting hose 402.

[0032] Specifically, the wooden boards in the enclosure box may have many burrs on the edges during the cutting process, which will affect the adhesion of the edge banding. Under the action of the sanding mechanism 4, the two sides of the wooden board will come into contact with multiple sanding wheels 407 in the sanding mechanism 4 during the translation process. Since the grit of the multiple sanding wheels 407 is set to increase from front to back, coarse sanding and fine sanding can be achieved first, ensuring the smoothness of the wooden board surface and ensuring the stability of the subsequent edge banding. In addition, after sanding, multiple micro scrapers 406 simultaneously come into contact with the sanded area, which can scrape off or loosen the wood chips generated and adhered during the sanding process, and then be sucked in by the vacuum cleaner 401 through the connecting hose 402 and the square dust collection chamber 405, thereby completing the thorough cleaning of wood chips and further ensuring the effect of the subsequent edge banding.

[0033] Working principle of the invention: When conveying and edge-sealing wooden boards, their two ends are centered by contacting the side limiting plates 901 in the limiting mechanism 9, and the conveyor track wheel set 7 slightly clamps their upper and lower sides. The limiting mechanism 9 uses corresponding limiting holes 904 at different positions and the engagement of bolts 905 to change the position of the side limiting plates 901 to accommodate wooden boards of different widths. Then, multiple rollers located above descend under the extension of the output end of the pneumatic strut 205 and press against the surface of the wooden board, forming a seal. The bottom plate 209 clamps and conveys the wooden board, and the rubber sleeve 207 increases the stable compression on the top of the wooden board to prevent the board from shifting. In this structure, compared with the existing technology, the central compression conveying replaces the two-sided compression conveying. The two-sided track wheel sets 7 can play the role of preventing edge warping, while making up for the problem of insufficient stability of a single support and ensuring the edge sealing effect. In addition, the two-way electric slide rail 5 can drive the two-sided conveying track wheel sets 7 to move horizontally. With the addition of the central conveying limiting structure, it can be adapted to the use of cofferdam boxes of different sizes.

[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
