Abstract
Description
Technical Field
[0001] This application relates to the field of wood door processing equipment technology, and more specifically, to a glue dispensing device for composite wood doors. Background Technology
[0002] Composite wood doors are constructed from multiple layers of cross-laminated wood panels. Glue is used to bond the layers together, enhancing the overall strength and stability of the composite wood door. Furthermore, after gluing, the composite wood door undergoes a pressing process to ensure the quality of the bonding between the wood layers.
[0003] In related technologies, depending on the specific process requirements, material characteristics, and cost-effectiveness of composite wood doors, a spot gluing process is generally used for bonding. The advantage of spot gluing is that it only applies glue to key bonding areas, avoiding waste of glue over large areas.
[0004] Traditionally, some dispensing machines use a separate robotic arm to move the dispensing head to different key locations on the wood board for dispensing. However, when dealing with large wood boards, the robotic arm's movement path is longer, which lengthens the entire dispensing cycle and reduces dispensing efficiency. Utility Model Content
[0005] In view of this, the present application provides a glue dispensing device for composite wood doors to solve the technical problem of low efficiency of glue dispensing machines when dispensing glue on large areas of wood panels in related technologies.
[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:
[0007] A glue dispensing device for composite wood doors, comprising:
[0008] A workbench, wherein a machine tool column is vertically installed at the top end of the workbench, and a base is also provided on the top surface of the workbench;
[0009] A telescopic hydraulic cylinder is fixedly installed at the top of the machine tool column. The telescopic hydraulic cylinder is located above the base. A bottle clamp is fixedly installed on the side of the drive rod of the telescopic hydraulic cylinder.
[0010] A glue storage bottle, which is fixedly mounted on the bottle clamp, is used to hold glue.
[0011] The cross rack consists of two perpendicularly intersecting hollow tubes to form a cross-shaped diversion structure. The center node of the cross rack is connected to the bottom of the glue storage bottle by a thread to achieve a sealed connection.
[0012] The dispensing frame consists of four hollow tubes connected end to end to form a rectangular flow distribution structure. The top surface of the dispensing frame is fixedly connected to the drive rod of the telescopic cylinder. The four top corners of the dispensing frame are connected and communicate with the four branch ends of the cross frame. The dispensing frame is located above the base.
[0013] The dispensing section includes multiple dispensing syringes, which are located at the apex corner of the bottom surface of the dispensing frame. Multiple helical springs are arranged around the dispensing syringes, and the two ends of the helical springs are respectively connected to the dispensing frame and the extrusion ring. The extrusion ring is sleeved on the dispensing syringe and located at its bottom end. The bottom dimension of the inner ring of the extrusion ring is smaller than its top dimension.
[0014] In some possible implementations, the worktable includes a first worktable and a second worktable, with a machine tool column vertically disposed at the top end of the first worktable, and the second worktable located above the first worktable and perpendicular to it.
[0015] In some possible implementations, a first track is provided at the top of the first worktable, and the second worktable is slidably connected to the first worktable via the first track.
[0016] In some possible implementations, a second track is provided at the top of the second worktable, and the base is slidably connected to the second worktable via the second track.
[0017] In some possible implementations, the area of the dispensing frame is smaller than the area of the top surface of the base.
[0018] In some possible implementations, the bottom surface of the dispensing frame and the top surface of the extrusion ring are both provided with spring posts connected to the helical spring.
[0019] In some possible implementations, the four branch ends of the cross frame are connected to the top entrance of the dispensing frame via rigid rubber tubes.
[0020] In some possible implementations, the sum of the length of the helical spring and the thickness of the extrusion ring is equal to the length of the dispensing syringe.
[0021] The adhesive dispensing device for composite wood doors provided in this application embodiment has at least the following beneficial effects:
[0022] In the composite wood door dispensing device provided in this application embodiment, the wood board to be glued is placed on the base of the workbench. A telescopic cylinder is driven to lower the dispensing frame until the dispensing part contacts the upper surface of the wood board. The telescopic cylinder continues to descend, causing the dispensing ring of the dispensing part to contact the upper surface of the wood board and compress the helical spring, simultaneously moving the dispensing syringe downwards. During this process, the dispensing syringe is squeezed by the extrusion ring, causing glue to flow from the syringe, thus achieving the glue dispensing treatment of the wood board. Using this structural design, the dispensing frame can be used to simultaneously dispense glue to multiple key locations on a large area of wood board, thereby greatly improving dispensing efficiency and increasing the production efficiency of composite wood doors.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0031] like Figures 1-4 As shown in the embodiment of this application, the adhesive dispensing device for composite wooden doors includes a worktable, a telescopic hydraulic cylinder 500, an adhesive storage bottle 600, an adhesive dispensing frame 800, and an adhesive dispensing section. A machine tool column 300 is vertically mounted on the top surface of the worktable near its end, and a base 400 is also provided on the worktable surface. The telescopic hydraulic cylinder 500 is fixedly mounted on the top of the machine tool column 300 and is located above the base 400. The drive rod of the telescopic hydraulic cylinder 500 can move vertically, and a bottle clamp 510 is fixedly mounted on the side of the drive rod of the telescopic hydraulic cylinder 500.
[0032] A glue storage bottle 600 is fixedly mounted on a bottle clamp 510. The glue storage bottle 600 is a container for storing glue. A cross bracket 700 is connected to the bottom of the glue storage bottle 600. The cross bracket 700 consists of two perpendicularly intersecting hollow tubes, and its interior forms a cross-shaped flow distribution structure. Furthermore, the center node of the cross bracket 700 is connected to the bottom of the glue storage bottle 600 via a threaded structure, and the two are sealed together by an O-ring. The glue stored inside the glue storage bottle 600 can flow downwards by gravity until it fills the flow distribution structure inside the cross bracket 700.
[0033] In this embodiment, the dispensing frame 800 is composed of four hollow tubes connected end to end to form a rectangular distribution structure. The dispensing frame 800 can be made of aluminum alloy. The top surface of the dispensing frame 800 is fixedly connected to the drive rod of the telescopic cylinder 500. The dispensing frame 800 is located above the base 400, and the area of the dispensing frame 800 is smaller than the area of the top surface of the base 400. The four apex positions of the bottom of the dispensing frame 800 are connected to the four branch ends of the cross frame 700. Preferably, the four apex positions of the dispensing frame 800 are respectively connected to the branch ends of the cross frame 700 through rigid adhesive tubes 810, and there is a one-to-one correspondence between the two.
[0034] Preferably, the rigid tubing 810 can be made of polytetrafluoroethylene (PTFE), and the rigid tubing 810 has a temperature resistance range of -50°C to 250°C to prevent the adhesive from curing inside and causing blockage.
[0035] Continue as Figures 1-4As shown, the dispensing unit includes multiple dispensing syringes 900 disposed on the bottom surface of the dispensing frame 800. Specifically, the dispensing syringes 900 are located at the top corners of the bottom surface of the dispensing frame 800. Multiple helical springs 910 are also disposed around the dispensing syringes 900, with both ends of the helical springs 910 connected to the bottom surface of the dispensing frame 800 and the extrusion ring 930, respectively. Furthermore, the extrusion ring 930 is sleeved on the outside of the dispensing syringes 900. Preferably, both the bottom surface of the dispensing frame 800 and the top surface of the extrusion ring 930 are provided with spring posts 920 connected to the helical springs 910.
[0036] When the helical spring 910 is in its initial state, the extrusion ring 930 is located at the bottom end of the dispensing syringe 900. That is, the sum of the length of the helical spring 910 and the thickness of the extrusion ring 930 is equal to the length of the dispensing syringe 900. The bottom dimension of the inner ring of the extrusion ring 930 is smaller than its top dimension; that is, the inner ring of the extrusion ring 930 has an inverted conical structure. This allows the extrusion ring 930 to compress the dispensing syringe 900 and apply glue to the wood board as it moves upwards.
[0037] In the adhesive dispensing device for composite wooden doors provided in this application embodiment, the wooden board to be glued is placed on the base 400 of the workbench. The telescopic cylinder 500 is driven to lower the dispensing frame 800 until the dispensing part contacts the upper surface of the wooden board. Controlling the telescopic cylinder 500 to continue lowering, the extrusion ring 930 of the dispensing part contacts the upper surface of the wooden board, compressing the spiral spring 910 and simultaneously causing the dispensing syringe 900 to move downwards. At the same time, the glue flows into the cross-shaped diversion structure inside the cross frame 700 under gravity in the glue storage bottle 600, and is then transported to the diversion structure inside the dispensing frame 800 through the rigid glue tube 810. Preferably, a flow control valve can also be provided at the rigid glue tube 810, allowing the operator to manually adjust the flow control valve to control the glue flow rate.
[0038] During the above process, the dispensing syringe 900 moves downwards when the helical spring 910 is compressed. Therefore, the inverted conical inner ring wall of the extrusion ring 930 presses against the glue outlet at the bottom of the dispensing syringe 900, causing the outlet to gradually expand from a closed state until the glue is released outwards from the bottom outlet of the dispensing syringe 900, thus achieving the dispensing treatment of the wood board. Using this structural design, the dispensing frame 800 can be used to simultaneously dispense glue to multiple key locations on a large area of wood board, greatly improving dispensing efficiency and increasing the production efficiency of composite wood doors.
[0039] Preferably, a miniature booster pump can be installed at the outlet of the glue storage bottle 600, or an exhaust valve can be added to the branch end of the cross frame 700 to remove air bubbles in the glue and prevent the glue from becoming clogged due to air bubbles during flow. Furthermore, using a low-viscosity glue allows it to flow naturally under gravity, while using a high-viscosity glue allows flow to be achieved by turning on the booster pump. In addition, an insulation layer can be provided over the cross frame 700 and the dispensing frame 800 to ensure that the glue flows at a specified temperature, thereby avoiding clogging problems.
[0040] In some embodiments, the worktable includes a first worktable 100 and a second worktable 200. A machine tool column 300 is vertically disposed at the top end of the first worktable 100, and the second worktable 200 is located above the first worktable 100, and the two are perpendicular to each other. Preferably, a first track 110 is disposed at the top of the first worktable 100, and the second worktable 200 is disposed at the top of the first worktable 100 via the first track 110.
[0041] Similarly, a second track 210 is provided at the top of the second worktable 200, and the base 400 is mounted on the top of the second worktable 200 via the second track 210. Through the above structural design, the base 400 can move freely on the XY axis of the plane, thereby enabling the base 400 to meet the usage requirements in different environments. All of the above processes can be driven by servo motors to achieve precise positioning.
[0042] Preferably, the dispensing syringe 900 can be connected to the dispensing frame 800 via a replaceable design such as a threaded connection, thereby facilitating periodic cleaning of the dispensing syringe 900 to remove the cured adhesive inside.
