Abstract
Description
Technical Field
[0001] This utility model relates to the field of wood processing technology, specifically to a tray for supporting edge banding. Background Technology
[0002] In custom furniture production, edge banding of wood panels is a crucial process for ensuring product quality and aesthetics. A stable supply of edge banding tape directly impacts the efficiency and quality of the edge banding machine. Currently, the tray used to support the edge banding tape in the edge banding tape feeding device is a core component, and its structural design significantly affects the stability of the feeding process, material changing efficiency, and adaptability.
[0003] In the existing technology, edge banding tape pallets generally have the following defects: First, limited adaptability. The positioning mechanism of traditional pallets is mostly designed with a fixed size, which can only match edge banding tape rolls with a specific inner diameter. When it is necessary to change the edge banding tape with a different inner diameter, the corresponding pallet or positioning accessories need to be replaced, which is cumbersome and has poor versatility. Second, inconvenient loading and unloading. Most pallets are connected to the feeding device by bolts or complex buckle structures. Changing the edge banding tape requires a lot of time for disassembly and installation, which leads to prolonged equipment downtime and affects production continuity.
[0004] Therefore, there is an urgent need to develop a pallet that can support edge banding. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a tray for carrying edge banding tape, which achieves stepless adjustment through an expansion mechanism to adapt to edge banding tapes of different specifications; enabling efficient loading and unloading of edge banding tape. The implementation of this technical solution is as follows: A pallet for carrying edge banding tape, comprising: A base plate, on which a chassis is mounted, the chassis being rotatably connected to the base plate; Edge sealing tape, which is located on the chassis; An expansion mechanism is fixed in the middle of the chassis and located in the inner ring of the edge banding. The expansion mechanism is used to tighten the edge banding. A guide belt, rotatably mounted on the base plate, is used to guide the feeding of the edge banding tape; A cylinder is fixed to a base plate, and the piston rod of the cylinder is connected to one end of the guide belt component to drive the guide belt component to rotate.
[0006] Preferably, it also includes a heating element, which is disposed below the base plate and is used to heat the edge sealing strip.
[0007] Preferably, the heating element is a graphene heating element.
[0008] Preferably, the expansion mechanism includes a plurality of expansion claws, a rotating wheel, and a fixing member. One end of the plurality of expansion claws is inserted into the rotating wheel, and the rotating wheel is used to drive the expansion claws to move, thereby opening and retracting the expansion claws. The fixing member is used to lock the rotating wheel to the chassis.
[0009] Preferably, the expansion claws are evenly distributed around the central axis of the wheel.
[0010] Preferably, one end of each of the expansion claws is provided with a rotating pin, and the rotating wheel is provided with a groove that matches the rotating pin; by manually rotating the rotating wheel, the rotating pin is driven to slide in the groove, so that the expansion claws extend and retract synchronously.
[0011] Preferably, the guide belt component is provided with an arc-shaped guide plate and an auxiliary wheel; the auxiliary wheel abuts against the edge sealing belt to guide the edge sealing belt so that it can be smoothly discharged; one end of the arc-shaped guide plate is fixedly connected to the piston rod of the cylinder.
[0012] Preferably, it also includes a rubber air seal, the purpose of which is to allow an external air source to enter the cylinder through the rubber air seal.
[0013] Preferably, the base plate is provided with a first through hole and a second through hole, through which a pipe for conveying the gas source passes.
[0014] Preferably, it also includes a guide belt seat, which is a straight plate shape and has a channel for accommodating the edge banding tape.
[0015] Compared with the prior art, this application has the following advantages: The pallet in this technical solution uses an expansion mechanism consisting of expansion claws and a rotating wheel. The expansion claws can be manually driven to extend and retract synchronously to achieve stepless adjustment. It can stably adapt to edge banding tapes with different inner diameters and is compatible with edge banding tapes of different specifications without changing positioning accessories. This solves the problem that traditional pallets can only adapt to fixed inner diameters and have poor versatility.
[0016] The guide belt component and the cylinder work together in this technical solution to adjust the posture of the arc-shaped guide plate in real time as the diameter of the edge banding tape decreases. Together with the auxiliary wheel that always abuts against the edge banding tape, it ensures a smooth transition of the edge banding tape feeding path throughout, avoiding problems such as roll jamming and path deviation caused by diameter changes.

[0022] Embodiments of this application provide a tray for carrying edge banding tape, used in conjunction with an edge banding tape feeding device, wherein the tray is mounted on the edge banding tape feeding device. For example... Figure 1-6 As shown, the pallet includes: a base plate 1, a chassis 10, an edge sealing strip 2, an expansion mechanism 3, a guide belt 4, and a cylinder 5; the chassis 10 is mounted on the base plate 1 and is rotatably connected to the base plate 1; the edge sealing strip 2 is located on the chassis 10; the expansion mechanism 3 is fixed in the middle of the chassis 10 and is located in the inner ring of the edge sealing strip 2; the expansion mechanism 3 is used to tighten the edge sealing strip 2; the guide belt 4 is rotatably mounted on the base plate 1 and is used to guide the edge sealing strip 2 for feeding; the cylinder 5 is fixed on the base plate 1, and the piston rod of the cylinder 5 is connected to one end of the guide belt 4 and is used to drive the guide belt 4 to rotate.
[0023] To better understand some embodiments of this application, one application scenario of a pallet for carrying edge banding 2 protected by this application is as follows: the edge banding 2 is in the form of a circular roll; in actual production, the circular roll edge banding 2 is a finished product and is directly installed on the pallet; when installing the edge banding 2 onto the pallet, the edge banding 2 is placed on the chassis 10, and the expansion mechanism 3 is rotated to open and tighten the edge banding 2, thereby realizing the installation of the edge banding 2; when conveying the edge banding 2, the edge banding 2 is gradually consumed, so the diameter of the circular roll edge banding 2 will gradually decrease. If there is no intervention, the pallet will jam during feeding; through the cooperation of the guide belt 4 and the cylinder 5, the edge banding 2 is smoothly conveyed and fed. The specific implementation process is described below.
[0024] In some implementations, such as Figure 1 and Figure 4 As shown, the expansion mechanism 3 is adapted to edge banding tapes 2 with different inner diameters. For example, the inner diameter of the circular rolled edge banding tape 2 may be different, some large and some small. The expansion mechanism 3 is set up to ensure the wide applicability of the pallet. The expansion mechanism 3 includes: several expansion claws 31, a rotating wheel 32 and a fixing member 33. One end of the several expansion claws 31 is inserted into the rotating wheel 32. The rotating wheel 32 is used to drive the expansion claws 31 to move, so as to realize the opening and retraction of the expansion claws 3041. The fixing member 33 is used to lock the rotating wheel 32 on the chassis 10.
[0025] Specifically, multiple expansion claws 31 are provided, preferably six expansion claws 31, which are evenly distributed around the central axis of the rotating wheel 32. Each expansion claw 31 has a rotating pin 311 at one end, and the rotating wheel 32 has a groove 321 that matches the rotating pin 311. The rotating pin 311 can slide within the groove 321. Preferably, the groove 321 is arc-shaped. By manually rotating the rotating wheel 32, the rotating pin 311 is driven to slide within the groove 321, causing the six expansion claws 31 to extend and retract synchronously. When rotating clockwise, the expansion claws 31 open and tighten the sealing strip 2; when rotating counterclockwise, the expansion claws 31 retract, at which point the expansion claws 31 no longer abut against the sealing strip 2, facilitating the removal of the sealing strip 2. Preferably, the fixing member 33 is a locking screw, which, when tightened, keeps all components of the expansion mechanism 3 in a fixed position. Therefore, the expansion claw 31 of the expansion mechanism 3, in conjunction with the rotating wheel 32, can open and retract the expansion claw 31. That is, the expansion mechanism 3 can abut against the ring-shaped sealing strip 2 with different inner diameters, so as to achieve stepless adjustment of the expansion mechanism 3.
[0026] In some implementations, such as Figure 2-3 As shown, the edge banding tape 2 is fed out from the guide belt component 4. The purpose of the guide belt component 4 is to cooperate with the cylinder 5 to make the edge banding tape 2 smoothly transition from the tray to the feeding device. Specifically, the guide belt component 4 is provided with an arc-shaped guide plate 41 and an auxiliary wheel 42. The auxiliary wheel 42 abuts against the edge banding tape 2 to guide the edge banding tape 2 so that it can be discharged smoothly. One end of the arc-shaped guide plate 41 is fixedly connected to the piston rod of the cylinder 5.
[0027] Specifically, when the edge banding 2 is first installed on the pallet assembly, the edge banding 2 is in a fully rolled state. At this time, the feeding path of the edge banding 2 has no bends and the feeding resistance is small. As the edge banding 2 is continuously fed, the diameter of the edge banding 2 gradually decreases, and the moving path of the edge banding 2 changes. At this time, the piston rod of the cylinder 5 slowly extends, driving the arc guide plate 41 to rotate, so that the arc surface of the arc guide plate 41 is in real time in contact with the inner surface of the reduced edge banding 2. During this process, the auxiliary wheel 42 also swings synchronously with the arc guide plate 41, always abutting the outer surface of the edge banding 2, ensuring that the edge banding 2 discharge transition is continuous and smooth.
[0028] In some implementations, such as Figure 5 As shown, the tray of this application also includes a heating element 6, which is disposed below the base plate 1 and is used to heat the edge sealing strip 2 to prevent the edge sealing strip 2 from hardening at low temperatures; the output end of the heating element 6 is a contact-type electrical terminal 61, which is fixed on the base plate 1 and is connected to an external power source to achieve electrical connection.
[0029] Preferably, the heating element 6 is a graphene heating element.
[0030] In some implementations, such as Figure 2 As shown, the tray of this application also includes a rubber air seal 7, the purpose of which is to allow an external air source to enter the cylinder 5 through the rubber air seal 7; specifically, the base plate 1 is provided with a first through hole 11 and a second through hole 12, through which a pipe for conveying the air source passes; the pipe for conveying the air source is used to connect the cylinder 5 and the rubber air seal 7, thereby realizing the conveying of air; it should be noted that the gas source described in this application is connected to an air pump, which is an external device used to provide the air source. The pressure of the air source is selected according to the requirements. The air pump is directly obtained from the prior art. Therefore, its structure is not specifically described in this application.
[0031] In some implementations, such as Figure 1 As shown, guide rails 9 are provided on both sides of the base plate, and the tray can be installed and removed by sliding the guide rails 9.
[0032] In some implementations, such as Figure 1-2 As shown, the pallet of this application also includes a guide seat 8, which is a straight plate shape and has a channel for accommodating the edge banding 2. The purpose of setting the guide seat 8 is to provide a rigid straight guide channel for the edge banding 2, pre-correct the arc and position of the edge banding 2 output, and ensure that the edge banding 2 is stably output from the pallet in a specified posture, thereby ensuring the edge banding quality and production continuity.
[0033] How this application works: When a tray for carrying edge banding tape is used in conjunction with an edge banding tape feeding device, it first slides and is unloaded from the feeding device via guide rails 9 on both sides of the base plate 1. When installing the edge banding tape 2, the edge banding tape 2 is placed on the base plate 10, and the rotating wheel 32 of the expansion mechanism 3 is rotated so that the rotating wheel 32 drives the expansion claw 31 to open synchronously through the sliding groove 321, thus tightening the inner ring of the edge banding tape 2 for fixation. If it is necessary to remove the edge banding tape 2, the rotating wheel 32 is rotated counterclockwise to retract the expansion claw 31. During feeding, the edge banding 2 is output from the guide belt 4. In the initial full roll state, the arc-shaped guide plate 41 of the guide belt 4 is in contact with the edge banding 2, and the auxiliary wheel 42 abuts against the outer surface of the edge banding 2 to ensure that the feeding path has no bends. As the diameter of the edge banding 2 decreases, the piston rod of the cylinder 5 on the base plate 1 slowly extends, driving the arc-shaped guide plate 41 to rotate, so that its arc surface is in real time in contact with the inner surface of the edge banding 2. The auxiliary wheel 42 swings synchronously to keep abutting against the edge banding 2, realizing a smooth transition of the edge banding 2. Finally, after the arc and position of the edge banding 2 are corrected by the guide belt seat 8, it is stably output to the feeding device.
[0034] The above are merely embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
