Description
Technical Field
[0001] This utility model relates to the technical field of woodworking equipment, specifically providing a sealing strip unwinding mechanism. Background Technology
[0002] Particleboard is a commonly used material for furniture making. It is a type of board produced by crushing wood, logs, or other timbers using a particleboard manufacturing process. It offers good decorative properties, is resistant to warping, and has strong nail-holding power. The surface of particleboard is typically finished with a melamine film, while the edges are sealed with edge banding. In mass production, the edge banding is usually in roll form, released to a suitable length from the roll and then glued to the edges of the particleboard.
[0003] The edge banding strip is unwound using an unwinding mechanism, which includes a turntable and support rods. The edge banding strip roll is fitted onto the support rods and is passively unwound by rotating the turntable. During the unwinding process, if the unwinding speed is too fast, the edge banding strip roll will cause the turntable to rotate due to inertia, potentially leading to the edge banding strip roll becoming loose and affecting subsequent unwinding operations.
[0004] Therefore, there is an urgent need for an edge sealing strip unwinding mechanism to solve the problem of edge sealing strip rolls becoming loose during the unwinding process. Utility Model Content
[0005] The present invention aims to solve the above-mentioned technical problem, namely, to solve the problem that the edge sealing strip roll may become loose during the unwinding process.
[0006] In a first aspect, the present invention provides an edge banding strip unwinding mechanism, comprising: a worktable; an unwinding assembly, wherein the edge banding strip roll is mounted on the unwinding assembly and the unwinding assembly is configured to rotate to release the edge banding strip; and a pressing assembly, configured to press the edge banding strip roll from the outer periphery to prevent the edge banding strip roll from loosening, comprising a base, a guide rod, a sliding seat, an elastic element, and a rolling roller, wherein the base is connected to the worktable, the guide rod is vertically fixed to the base, the sliding seat is sleeved on the guide rod and slidably connected along the guide rod, and the elastic element is connected to the sliding seat and is used to drive the rolling roller to contact and squeeze the outer periphery of the edge banding strip roll, wherein the rolling roller makes rolling contact with the outer periphery of the edge banding strip roll.
[0007] By adopting the above technical solution, the rolling roller can contact and squeeze the edge sealing strip roll under the elastic force of the elastic element, and press the edge sealing strip roll tightly, so that the inside of the edge sealing strip roll is always taut and will not loosen. Even if the edge sealing strip roll releases a part of the edge sealing strip due to inertial rotation, the released edge sealing strip is difficult to rebound back into the edge sealing strip roll under the action of the rolling roller and the edge sealing strip roll, thus preventing the edge sealing strip roll from loosening.
[0008] In a specific embodiment of the above-mentioned edge banding unwinding mechanism, the guide rods include at least two, and the sliding seat is slidably connected to at least two guide rods simultaneously.
[0009] By adopting the above technical solution, after the sliding seat is slidably connected with at least two guide rods, it can effectively prevent the sliding seat from rotating relative to the guide rods, thus avoiding affecting the fit between the rolling roller and the edge sealing strip roll.
[0010] In a specific embodiment of the above-mentioned edge banding unwinding mechanism, the sliding seat includes a mounting part and a seat body. The seat body is slidably connected to the guide rod, and a stepped surface is formed between the mounting part and the seat body. The rolling roller is connected to the mounting part through a sliding member. The sliding member is sleeved on the outer periphery of the mounting part and slides along the length direction of the mounting part. The rolling roller is fixed to the sliding member. The elastic member is a spring. The spring is sleeved on the outer periphery of the mounting part, and its two ends abut against the sliding member and the seat body, respectively.
[0011] By adopting the above technical solution, the spring can provide elastic force to push the sliding part and the rolling roller closer to the edge sealing strip roll material, ensuring that the rolling roller can contact and squeeze the edge sealing strip roll material.
[0012] In a specific embodiment of the above-mentioned edge banding unwinding mechanism, a stop is provided on the circumferential surface of the mounting part. The stop is sleeved on the circumferential surface of the mounting part and threadedly connected to the mounting part. The stop is located on the side of the sliding member away from the guide rod and is used to restrict the movement of the sliding member.
[0013] By adopting the above technical solution, the stop can limit the maximum range of movement of the sliding part and prevent the sliding part from detaching from the mounting part.
[0014] In a specific embodiment of the above-mentioned edge banding unwinding mechanism, a limiting member is fixedly provided at the end of the mounting part away from the guide rod, and the limiting member is located on the side of the edge banding roll when it is working.
[0015] By adopting the above technical solution, the limiting component can block the edge sealing strip roll on the side, preventing the edge sealing strip roll from becoming loose and detaching on the side.
[0016] In a specific embodiment of the above-mentioned edge banding unwinding mechanism, the edge banding unwinding mechanism further includes: a guide assembly, which includes a guide bracket and two guide rollers. The guide rollers are arranged in parallel and rotatably connected to the guide bracket. The guide bracket is fixedly connected to the sliding seat. The edge banding released from the edge banding roll is located between the two guide rollers.
[0017] By adopting the above technical solution, the guide component can guide the released edge banding strip to ensure that the edge banding strip can smoothly enter the next process; in addition, the guide component can also prevent the released edge banding strip from shrinking back, thereby reducing the possibility of the edge banding strip roll becoming loose.
[0018] In a specific embodiment of the above-mentioned edge banding unwinding mechanism, the edge banding unwinding mechanism further includes: a moving component, installed on the workbench, used to drive the pressing component to approach or move away from the edge banding roll.
[0019] By adopting the above technical solution, the position of the pressing component on the worktable can be changed by moving the component, which facilitates the replacement of the edge sealing strip roll and also makes it easier to match the pressing component with the edge sealing strip roll.
[0020] In a specific embodiment of the above-mentioned edge banding unwinding mechanism, at least one slide rail is provided on the workbench, and the base is slidably connected to the slide rail; the moving component includes a support plate, a lead screw and a slider, the support plate is fixed to the workbench, the lead screw is rotatably connected to the support plate, the slider is threadedly connected to the lead screw, and the base is fixedly connected to the slider.
[0021] By adopting the above technical solution, rotating the lead screw can drive the slider to move, thereby driving the base to move along the slide rail, so as to change the position of the pressing assembly relative to the worktable.
[0022] Compared with the prior art, the present invention has at least the following advantages:
[0023] The edge banding strip unwinding mechanism provided by this utility model includes a worktable, an unwinding assembly, and a pressing assembly. The edge banding strip roll is installed on the unwinding assembly, which is configured to rotate to release the edge banding strip.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.
[0032] To address the issue of edge banding strip rolls potentially becoming loose during unwinding, this utility model provides an edge banding strip unwinding mechanism. For example... Figure 1 and Figure 2As shown, the edge banding unwinding mechanism includes a worktable 1, an unwinding assembly 2, a pressing assembly 3, and a moving assembly 4. The unwinding assembly 2 is mounted on the worktable 1, and the edge banding roll 6 is mounted on the unwinding assembly 2. The unwinding assembly 2 can passively rotate to release the edge banding 61 under external force. The moving assembly 4 is located on the worktable 1 and is used to drive the pressing assembly 3 closer to or away from the unwinding assembly 2. Driving the pressing assembly 3 away from the unwinding assembly 2 facilitates the replacement of the edge banding roll 6. Driving the pressing assembly 3 closer to the unwinding assembly 2 allows the pressing assembly 3 to cooperate with the edge banding roll 6 to press it tightly. The pressing assembly 3 is configured to press the edge banding roll 6 from its outer periphery to prevent it from loosening.
[0033] like Figure 1 and Figure 2 As shown, the pressing assembly 3 includes a base 31, a guide rod 32, a sliding seat 33, an elastic element 34, and a rolling roller 35. The base 31 is connected to the worktable 1 via a moving assembly 4, meaning the moving assembly 4 can adjust the position of the pressing assembly 3 relative to the worktable 1 by adjusting the position of the base 31 relative to the worktable 1. The guide rod 32 is vertically fixed to the base 31. The sliding seat 33 is sleeved on the guide rod 32 and slidably connected along the guide rod 32 to change the height of the sliding seat 33 relative to the worktable 1, accommodating edge sealing strip rolls 6 of different widths. The elastic element 34 is connected to the sliding seat 33 and is used to drive the rolling roller 35 to contact and squeeze the outer periphery of the edge sealing strip roll 6, with the rolling roller 35 making rolling contact with the outer periphery of the edge sealing strip roll 6. Under the elastic force of the elastic element 34, the rolling roller 35 can contact and squeeze the edge sealing strip roll 6, pressing the edge sealing strip roll 6 tightly, so that there is a certain rolling friction between the edge sealing strip roll 6 and the rolling roller 35. When the edge banding roll 6 is excessively released due to factors such as inertial rotation, the released edge banding 61 is located outside the contact point between the edge banding roll 6 and the rolling roller 35. It is difficult to overcome the friction between the edge banding roll 6 and the rolling roller 35 to make the released edge banding 61 spring back to the edge banding roll 6. Therefore, the possibility of the edge banding roll 6 becoming loose is relatively small.
[0034] When there is only one guide rod 32, due to the extrusion force between the edge sealing strip roll 6 and the rolling roller 35, if the angle of the extrusion force does not coincide with the radial direction of the edge sealing strip roll 6, the sliding seat 33 can easily rotate relative to the guide rod 32 during the unwinding process. Therefore, at least two guide rods 32 can be provided, and the sliding seat 33 can be slidably connected to at least two guide rods 32 simultaneously. This effectively prevents the sliding seat 33 from rotating relative to the guide rods 32 and affecting the fit between the rolling roller 35 and the edge sealing strip roll 6.
[0035] In the examples of this utility model, such as Figure 2As shown, the elastic element 34 is a spring. Specifically, the sliding seat 33 includes a mounting part 331 and a seat body 332. The seat body 332 is slidably connected to the guide rod 32. The mounting part 331 is columnar, tubular, or square tubular, and a stepped surface is formed between the mounting part 331 and the seat body 332. The rolling roller 35 is connected to the mounting part 331 via a sliding element 38. The sliding element 38 is sleeved on the outer periphery of the mounting part 331 and slides along the length direction of the mounting part 331. The rolling roller 35 is fixed to the sliding element 38. The elastic element 34, which is a spring, is sleeved on the outer periphery of the mounting part 331, and its two ends abut against the sliding element 38 and the seat body 332, respectively. At this time, the spring can provide elastic force to push the sliding element 38 and the rolling roller 35 closer to the edge sealing strip roll 6, ensuring that the rolling roller 35 can contact and squeeze the edge sealing strip roll 6.
[0036] In order to limit the maximum range of movement of the slider 38 and prevent the slider 38 from disengaging from the mounting part 331, in this example of the utility model, a stop 36 is provided on the circumferential surface of the mounting part 331. The stop 36 is sleeved on the circumferential surface of the mounting part 331 and threadedly connected to the mounting part 331. The stop 36 is located on the side of the slider 38 away from the guide rod 32, thereby limiting the movement of the slider 38.
[0037] Of course, in other possible examples, the elastic element 34 can specifically be a gas spring, a cylinder, etc.
[0038] In some cases, after the edge banding roll 6 becomes loose, it will scatter and come off along the axial direction (i.e., the side) of the edge banding roll 6, making it difficult to unwind properly. Therefore, in this example, a limiting member 37 is provided. The limiting member 37 is fixed to the end of the mounting part 331 away from the guide rod 32, and when in operation, the limiting member 37 is located on the side of the edge banding roll 6. The limiting member 37 can block the edge banding roll 6 from coming off the side, preventing it from becoming loose and coming off.
[0039] In a specific example of this utility model, the moving component 4 includes a support plate 41, a lead screw 42, a slider 43, and a driving component 44. The support plate 41 is fixed to the worktable 1, the lead screw 42 is rotatably connected to the support plate 41, the slider 43 is threadedly connected to the lead screw 42, and the base 31 is fixedly connected to the slider 43. The driving component 44 is used to drive the lead screw 42 to rotate. The worktable 1 is provided with at least one slide rail 11, and the base 31 is slidably connected to the slide rail 11 to improve the stability between the base 31 and the worktable 1. Rotating the lead screw 42 can drive the slider 43 to move, thereby driving the base 31 to move along the slide rail 11 to change the position of the pressing component 3 relative to the worktable 1.
[0040] In some examples, the edge banding unwinding mechanism further includes a guide assembly 5, which includes a guide bracket 51 and two guide rollers 52. The guide rollers 52 are arranged in parallel and rotatably connected to the guide bracket 51. The guide bracket 51 is fixedly connected to the sliding seat 33. The edge banding 61 released from the edge banding roll 6 is located between the two guide rollers 52. In one aspect, the guide assembly 5 can guide the released edge banding 61 to ensure that the edge banding 61 can smoothly enter the next process. In addition, the guide assembly 5 can also prevent the released edge banding 61 from retracting, thereby reducing the possibility of the edge banding roll 6 becoming loose.
[0041] It should be noted that the guide rollers 52 are all passive rollers. The gap between two cooperating guide rollers 52 is less than or equal to the thickness of the edge banding strip 61, so as to ensure that the two cooperating guide rollers 52 can clamp the edge banding strip 61, thereby increasing the friction between the guide rollers 52 and the edge banding strip 61 and improving the reliability of the guide assembly 5 in preventing the edge banding strip 61 from retracting.
[0042] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
