Description

Technical Field

[0001] The utility model relates to the technical field of gluing, in particular to a self-locking gluing device. Background Art

[0002] This section only provides background information related to the present application to facilitate technicians / members in this field to understand the present application more thoroughly and accurately, and it is not necessarily prior art.

[0003] Boards are the most common raw materials in the production of various types of furniture. Through the splicing and installation of boards, various types of furniture with various functions can be formed. Among them, after the boards are cut into specific sizes, they need to be further painted, veneered or veneered.

[0004] In the current welt operation, the two sides of the board are generally exposed surfaces, and the two ends are splicing surfaces. The conventional board welt process is to apply glue on the exposed surfaces on both sides of the board, and then adhere the welt strips to the two sides of the board to achieve the bonding action. When applying glue, a glue pot is usually set on the machine body, and the glue in the glue pot is introduced into the position of the glue roller, and the glue roller is rolled in contact with the side of the board to achieve glue coating.

[0005] In order to make the glue coating roller have a higher gluing accuracy, the sheet is generally guided to the glue coating roller position by the guide plate on the machine body. Under the action of the guide plate, the sheet can keep a certain gluing interval between the glue coating roller and the side of the sheet, that is, the sheet can be glued just when it reaches the glue coating roller position without the glue coating roller and the sheet hitting each other. However, after the end of the sheet is separated from the guide plate, the glue coating roller will hit the sheet under the action of the spring, resulting in glue pressure marks or pinholes at the end of the sheet, resulting in uneven glue coating.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] See also Figure 1-Figure 5The utility model discloses a self-locking glue coating device, including a glue coating seat 10, a glue coating roller 20, a glue roller seat 30 and a self-locking mechanism. A guide member 11 is provided on the glue coating seat 10, and the glue coating roller 20 is rotatably mounted on the glue coating seat 10, and the bottom end of the glue coating roller 20 extends from the bottom end of the glue coating seat 10 and is rotatably mounted on the glue roller seat 30, that is, the glue coating roller 20 can be rotatably mounted with the glue roller seat 30 as a base, and rotate relative to the glue coating seat 10. The guide member 11 and the glue coating roller 20 are sequentially distributed in the conveying direction of the plate, and the guide member 11 can guide the plate to move to the glue coating roller 20 along the conveying direction of the plate, and due to the function of the guide member 11, a certain glue coating interval can be provided between the plate and the glue coating roller 20, and the glue coating interval can be provided for the plate to be conveyed to the glue coating roller 20, so that the glue liquid can be coated on the side of the plate.

[0030] Specifically, the self-locking mechanism includes a locking seat 41, a linkage rod 43, an elastic component 44 and a locking piece. One end of the linkage rod 43 is extended from the locking seat 41 to form a movable end 431, and the other end of the linkage rod 43 is movably connected to the locking seat 41 to form a locking end. In addition, the movable end 431 can be movably connected to the rubber roller seat 30. The elastic component 44 is arranged between the rubber roller seat 30 and the movable end 431 and can provide elastic stress. Under the action of the elastic stress, the glue roller 20 can be close to the guide plate and can maintain the glue-coated state. Under the action of the elastic stress, the glue roller 20 is in elastic contact when applying glue to the plate, and there will be no jamming. The locking piece can lock the locking end of the linkage rod 43.

[0031] On the basis of the above structure, when using the self-locking gluing device of the utility model, the self-locking gluing device can be applied to a plate edge pasting machine, and the plate is conveyed to the position of the self-locking gluing device under the action of the plate conveying mechanism. During normal gluing, the plate can be conveyed close to the guide member 11, and reaches the position of the gluing roller 20 under the guidance of the guide member 11. Due to the action of the guide member 11, the plate can maintain a certain gluing interval with the gluing roller 20 when being conveyed to the position of the gluing roller 20, so that the glue can be evenly applied to the side of the plate, and it is not easy to overflow or leak glue.

[0032] At the same time, in order to enable the glue coating roller 20 to maintain a coated state with the plate under a certain tension, the glue coating roller 20 in this embodiment is assembled with the glue roller seat 30 as the rotation basis. Since an elastic component 44 is provided between the glue roller seat 30 and the movable end 431 of the linkage rod 43, the locking seat 41 is fixedly connected to the machine body, and the glue roller seat 30 can move toward the guide member 11 under the elastic stress of the elastic component 44, so that the glue coating roller 20 on the glue roller seat 30 can maintain a close gluing state under the elastic stress.

[0033] Due to the setting of the elastic component 44, when the sheet is guided to the end by the guide member 11, the sheet will be separated from the guide member 11. The sheet is not restricted by the guide member 11, and the glue roller 20 is also affected by the elastic stress of the elastic component 44. At this time, the end of the sheet will collide with the glue roller 20, resulting in glue pinholes at the end of the sheet. Therefore, in this embodiment, the locking end can be locked by the locking member during the glue coating process of the sheet, so that the movable rod of the linkage rod 43 can remain relatively fixed. After the sheet is separated from the guide member 11, the glue roller 20 will not be pressed by the elastic stress, and thus will not collide with the sheet, thereby improving the glue coating quality.

[0034] Furthermore, a driving groove can be provided on the rubber roller seat 30, and a driving block 432 can be provided at the movable end 431 accordingly. The driving block 432 is embedded in the driving groove, and the elastic component 44 is sleeved on the movable end 431. The elastic component can apply an elastic stress to the driving block to drive the driving block close to the driving groove. In this way, the linkage between the linkage rod 43 and the rubber roller seat 30 can also be limited by the fit between the driving block 432 and the driving groove. In this way, the assembly structure is more stable, and the above-mentioned elastic component 44 can be sleeved outside the movable end 431, and the applied elastic stress can drive the driving block to press the rubber roller seat with the driving block embedded in the driving groove as the linkage basis, so that the force is uniform and stable.

[0035] In addition, a shaft sleeve or the like can be provided at the movable end of the linkage rod to form a step structure. After the elastic component is mounted on the linkage rod, it can be clamped between the step structure and the driving block, so that the elastic component can be compressed to store energy and provide elastic stress.

[0036] It should be noted that the elastic component 44 in this embodiment can be made of elastic materials such as springs or elastic rubber blocks in the prior art.

[0037] Furthermore, the above-mentioned locking member includes a locking rod 45 and a locking rod driving member. The locking rod driving member can drive the locking rod 45 to move closer to or away from the locking end. In this way, when the linkage rod 43 is locked, the locking rod driving member can drive the locking rod 45 to move closer to the locking end of the linkage rod 43. In this way, after moving closer to the locking end, the locking rod 45 can be abutted and locked with the locking end to limit the movement of the locking rod 45.

[0038] When unlocking, the locking rod 45 only needs to be driven away from the locking end by the locking rod driving member, so that the linkage rod 43 can move freely.

[0039] In this way, unlocking or locking is achieved through the locking rod driving member, which is convenient for automatic control.

[0040] Specifically, a locking portion may be provided at the end of the locking rod 45 , and the locking portion may be positioned against the locking end, so that the locking portion can be positioned against the locking end of the linkage rod 43 , so that the locking structure is more stable.

[0041] In this embodiment, a locking groove can be provided at the end of the locking rod 45, and the locking groove can be used for the locking end to be embedded and positioned after moving close to the locking end. In this way, the locking groove forms a locking part, that is, the locking groove and the locking end of the linkage rod 43 can be embedded with each other to achieve positioning and locking.

[0042] Of course, a locking hole may be provided at the locking end of the linkage rod 43, and a locking block may be provided at the end of the locking rod 45, so that the locking action can be achieved by inserting the locking block into the locking hole. In addition, a claw structure may be provided at the end of the locking rod 45, so that the locking rod 45 can be locked by the claw after approaching the locking end.

[0043] The locking member may also be a bolt structure in the prior art, and locking or unlocking can be achieved by screwing the tail of the bolt into or out of the locking seat 41.

[0044] Furthermore, the inner wall of the locking groove is an arc surface that matches the outer surface structure of the locking end, so that after the locking rod 45 moves close to the locking end, the arc surface of the locking groove can match the outer surface arc of the linkage rod 43, and the structure is stable after engagement.

[0045] In addition, a structure such as a rubber pad may be further provided in the locking groove so that the rubber pad contacts the surface of the locking end, thereby increasing the locking friction force.

[0046] Furthermore, the locking rod driving component is a driving cylinder 42, the cylinder body of the driving cylinder 42 is installed on the locking seat 41, and the piston rod of the driving cylinder 42 is connected to the locking rod 45. In this way, the locking rod 45 can be moved closer or farther away by extending and retracting the piston rod of the driving cylinder 42 to achieve locking or unlocking action.

[0047] Furthermore, in order to realize the assembly of a stable self-locking structure, a through-connection groove and a locking hole can be provided in the locking block, and the linkage rod 43 can be movably connected to the through-connection groove, and the locking hole and the through-connection groove are connected, so that the linkage rod 43 can be assembled based on the through-connection groove, and the through-connection groove can also guide the axial movement of the linkage rod 43. When locking, the locking rod 45 can extend into the through-connection groove through the locking hole to close to the locking end for locking action. When unlocking, the locking rod 45 can enter the locking hole and exit the through-connection groove to complete the unlocking action away from the locking end.

[0048] On the basis of the structure without the through groove, a sliding groove structure can also be provided on the surface of the locking seat 41, so that the linkage rod 43 slides along the sliding groove, and the locking rod 45 directly moves toward or away from the sliding groove.

[0049] Furthermore, the guide member 11 is a guide plate, which extends along the conveying direction. The guide plate is guided by the guide plate, so that the guide surface is larger and the guide structure is more stable.

[0050] Furthermore, the glue coating seat 10 is provided with a glue outlet chamber, an outlet and a rotating chamber. The glue outlet chamber is used to fill the glue, and the outlet is used to connect the glue outlet chamber and the rotating chamber; the glue coating roller 20 can be rotatably connected to the rotating chamber, and extends from the bottom end of the rotating chamber and is rotatably installed on the glue roller seat 30.

[0051] When the glue is applied, the glue is filled in the glue outlet cavity, and the glue can be guided to the rotating cavity through the outlet. The glue coating roller 20 in the rotating cavity can adhere to the glue, and the glue on the glue coating roller 20 can roll in contact with the plate to achieve glue coating.

[0052] Of course, a glue pot may be directly provided on the glue coating seat 10 , and the glue outlet in the glue pot may be conveyed to the rotating chamber to achieve glue adhesion of the glue coating roller 20 . The specific selection may be made according to actual needs.

[0053] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
