Description

Technical Field

[0001] This application relates to the technical field of lantern processing, and in particular to an apparatus for attaching decorative strips to the decorative plate of a lantern. Background Technology

[0002] A lantern is a traditional lighting and decorative appliance, typically consisting of an upper plate, a lower plate, a lampshade, and a handle. The upper plate is usually round and located at the top of the lantern, serving to support the handle and secure the lampshade. Some lanterns also feature exquisite carvings or decorative bands on their upper plates.

[0003] Traditionally, the process of attaching decorative strips to the upper plate requires manual application.

[0004] Manually attaching decorative strips to the outer circumference of the upper plate is inefficient. Utility Model Content

[0005] In order to improve the efficiency of attaching decorative strips to the upper plate of a lantern, this application provides a device for attaching decorative strips to the upper plate of a lantern decoration.

[0006] The device for attaching decorative strips to the upper plate of a lantern decoration provided in this application adopts the following technical solution:

[0007] A device for attaching decorative strips to the upper plate of a lantern decoration includes a worktable. The worktable is equipped with a feeding cylinder, a discharging cylinder, a driving wheel, a driven wheel, and a cutting assembly. The feeding cylinder and the discharging cylinder are fixed to the worktable with their piston ends facing each other. The driving wheel is rotatably mounted on the worktable with its rotation axis vertically aligned. The driven wheel is slidably mounted on the worktable and slides towards or away from the driving wheel. The driving wheel and the driven wheel are distributed on both sides of the line connecting the feeding cylinder and the discharging cylinder. The cutting assembly is located above the driving wheel and is used for cutting the decorative strip. The piston end of the discharging cylinder is equipped with a clamp for dragging the upper plate.

[0008] By adopting the above technical solution, the feeding cylinder pushes the upper plate to move between the driving wheel and the driven wheel. The driven wheel moves towards the driving wheel, clamping the upper plate between the driving wheel and the driven wheel. The driving wheel starts to rotate, thereby driving the upper plate to rotate. Then, decorative strips are pasted on the outer wall of the upper plate. After pasting, the cutting component cuts the decorative strips. The driven wheel moves away from the driving wheel, and the unloading cylinder drags the upper plate away through the clamp. The whole process improves the efficiency of pasting decorative strips on the upper plate.

[0009] Optionally, the workbench is fixed with slide rails. Two slide rails are provided for supporting the upper plate. The slide rails are symmetrically distributed on both sides of the feeding cylinder and the unloading cylinder. The length of the slide rails is set along the direction of the line connecting the feeding cylinder and the unloading cylinder.

[0010] By adopting the above technical solution, the two slide rails provide a stable mounting track for the upper plate, ensuring that the upper plate moves in a fixed direction during the feeding and unloading process, avoiding deviation or shaking, so that the upper plate can be accurately grabbed by the clamp and placed between the driving wheel and the driven wheel, ensuring the stability and reliability of the device operation, thus providing a basic guarantee for the efficient application of decorative tape.

[0011] Optionally, the clamping component includes a base, a flipping block, and a torsion spring. The base is fixed to the piston end of the feeding cylinder. The flipping block is rotatably mounted on the base with its rotation axis set in the horizontal direction. The flipping block is a right-angled triangle shape, and the inclined side of the flipping block is an arc-shaped concave shape. When the flipping block is not subjected to external force, the torsion spring ensures that one end of the right-angled long side of the flipping block is always in a horizontal state.

[0012] By adopting the above technical solution, the unique structure of the clamp allows it to automatically adapt to the gripping and releasing of the upper plate. When gripping the upper plate, the feeding cylinder pushes the upper plate until it contacts the flipping block and continues to push it. The inclined edge of the curved concave part of the flipping block slides against the upper plate, and at the same time, the flipping block begins to flip. Then the upper plate passes over the flipping block, and the elastic force provided by the torsion spring ensures that the flipping block returns to its original position with its long side still horizontal. At this time, the clamp is located inside the upper plate, and the right-angled short side of the flipping block is vertical. Due to the presence of the slide rail, the flipping block will not affect the rotation processing of the upper plate. After the decorative strip is pasted on the outer wall of the upper plate, the unloading cylinder is activated, and the right-angled short side of the flipping block abuts against the inner wall of the upper plate and drags the upper plate away.

[0013] Optionally, the workbench is provided with receiving components. There are two receiving components symmetrically distributed on both sides of the feeding cylinder. The receiving components include a first motor, a first conveyor wheel, a second conveyor wheel, and a belt. The first motor is fixed on the workbench and its output end is fixedly connected to the first conveyor wheel. The second conveyor wheel is rotatably mounted on the workbench and its rotation axis is arranged in the vertical direction. The belt is simultaneously looped around the first and second conveyor wheels and is in a tensioned state. The upper plate abuts against both belts at the same time.

[0014] By adopting the above technical solution, the two belts of the receiving component are symmetrically distributed on both sides of the feeding cylinder. When the upper plate is dragged to the belt by the clamping part, the upper plate simultaneously abuts against the two belts. The first motor drives the first conveyor wheel to rotate, which drives the second conveyor wheel through the belt, thereby driving the upper plate to move smoothly. Then the upper plate passes over the tilting block again and is conveyed to the subsequent process.

[0015] Optionally, the cutting assembly includes electric scissors and a cutting cylinder, with the cutting cylinder vertically fixed on the worktable and its piston end facing downwards and fixedly connected to the electric scissors.

[0016] By adopting the above technical solution, the cutting cylinder can precisely control the lifting and lowering of the electric scissors. When the decorative strip is wound to the appropriate length, the cutting cylinder pushes the electric scissors to move down quickly, making a clean and neat cut to the decorative strip. Compared with manual cutting, it is faster and more accurate, avoids the problem of inconsistent length of the decorative strip, improves the efficiency and aesthetics of the decorative strip, and the use of electric scissors reduces the labor intensity of manual operation.

[0017] Optionally, a second motor is fixed below the worktable, and the rotating shaft of the second motor passes through the worktable and is fixedly connected to the drive wheel.

[0018] By adopting the above technical solution, the second motor under the workbench directly drives the drive wheel to rotate, and the power transmission is stable and reliable. It can provide continuous and strong power to the drive wheel, ensuring that the drive wheel drives the upper plate to rotate stably, so that the decorative strip can be evenly and tightly wrapped around the outer circumference of the upper plate, ensuring the efficient performance of the bonding process. At the same time, it simplifies the transmission structure and reduces the probability of equipment failure.

[0019] Optionally, there are two driven wheels, which are arranged in a triangular shape in conjunction with the driving wheel. A displacement cylinder is fixed on the worktable, and the displacement cylinder pushes the two driven wheels to move closer to or further away from the driving wheel.

[0020] By adopting the above technical solution, the two driven wheels and the driving wheel are arranged in a triangular shape. Driven by the displacement cylinder, the distance between them and the driving wheel can be flexibly adjusted to accommodate upper plates of different diameters. When processing upper plates of different specifications, the displacement cylinder drives the driven wheels to move closer to or further away from the driving wheel, ensuring that the three wheels tightly clamp the upper plate. This prevents slippage or displacement of the upper plate during rotation, enhancing the versatility and applicability of the device and expanding its application range.

[0021] Optionally, a positioning cylinder is provided on the worktable. The piston end of the positioning cylinder is positioned downward and a positioning disc is fixed thereon. The positioning disc is used to be inserted into the upper plate, and the outer wall of the positioning disc rolls against the upper plate.

[0022] By adopting the above technical solution, the piston end of the positioning cylinder drives the positioning plate to move downward, inserting the positioning plate into the upper plate. The outer wall of the positioning plate rolls against the upper plate, accurately positioning it without affecting the rotation of the upper plate. This prevents the upper plate from axially displacing or shaking during rotation, ensuring that the decorative strip can be evenly and neatly pasted along the circumference of the upper plate, improving the accuracy and quality of the decorative strip pasting, and making the decorative effect of the lantern upper plate more beautiful and standardized.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. Through the coordinated operation of the feeding cylinder, the unloading cylinder, the driving wheel and the driven wheel, the automatic feeding, positioning, rotation and decorative tape pasting of the upper plate are realized, replacing the traditional manual operation, improving the pasting efficiency and greatly reducing labor and time costs;

[0025] 2. The slide rail and positioning cylinder ensure that the upper plate moves along a fixed trajectory and is accurately positioned, while the displacement cylinder drives the driven wheel to flexibly adjust the spacing;

[0026] 3. The drive wheel drives the upper plate to rotate at a constant speed, which, together with the precise cutting of the cutting component, ensures that the decorative strip is wrapped evenly and of consistent length. Attached Figure Description

[0032] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0033] This application discloses an apparatus for attaching decorative strips to the upper plate of a lantern decoration.

[0034] refer to Figure 1 A device for attaching decorative strips to the upper plate of a lantern decoration includes a worktable 1. A feeding cylinder 11 and a discharging cylinder 12 are fixed on the worktable 1, with their piston ends facing each other to form a conveying path for the upper plate. Two slide rails 15 are symmetrically arranged along this path on the worktable 1 to support the upper plate and guide its linear movement.

[0035] refer to Figure 1 and Figure 2The worktable 1 is equipped with a drive wheel 13, a second motor 131, a displacement cylinder 141, and two driven wheels 14. The drive wheel 13 is rotatably mounted on the worktable 1 via bearings, and its rotation axis vertically passes through the worktable 1 and is fixedly connected to the output shaft of the second motor 131 below. The second motor 131 drives the drive wheel 13 to rotate. The piston end of the feeding cylinder 11 can push the upper plate to move along the slide rail 15 towards the drive wheel 13. The two driven wheels 14 are symmetrically distributed on both sides of the drive wheel 13 and are slidably connected to the linear guide rail on the worktable 1 via sliders. The displacement cylinder 141 is fixed on the worktable 1 and pushes the driven wheels 14 to reciprocate in the direction of approaching or moving away from the drive wheel 13. The two driven wheels 14 and the drive wheel 13 form a triangular clamping structure to accommodate upper plates of different diameters.

[0036] refer to Figure 3 , Figure 2 and Figure 4 A locking element 3 is fixed to the piston end of the feeding cylinder 12. The locking element 3 includes a base 31, a tilting block 32, and a torsion spring 33. The base 31 is fixed to the piston end. The tilting block 32 is a right-angled triangle with an arc-shaped concave hypotenuse. It is rotatably connected to the base 31 via a horizontal pin. The torsion spring 33 is sleeved on the pin, so that the long right-angle side of the tilting block 32 remains horizontal when no force is applied. When gripping the upper plate, the feeding cylinder 11 pushes the upper plate into contact with the tilting block 32. The upper plate squeezes the tilting block 32 to rotate around the pin. After passing the tilting block 32, the torsion spring 33 returns to its original position, so that the short right-angle side of the tilting block 32 is vertically pressed against the inner wall of the upper plate. At this time, the feeding cylinder 12 can drag the upper plate to move.

[0037] refer to Figure 1 and Figure 2 A cutting assembly 2 and a receiving assembly 4 are installed above the workbench 1. The cutting assembly 2 includes a cutting cylinder 22 and an electric scissors 21. The cutting cylinder 22 is vertically fixed to the edge of the workbench 1, and the piston end is connected to the electric scissors 21, which can quickly cut the decorative strip after it is wrapped. The receiving assembly 4 is provided in two sets, symmetrically distributed on both sides of the feeding cylinder 12. Each set includes a first motor 41, a first conveyor wheel 42, a second conveyor wheel 43, and a belt 44. The first motor 41 is fixed on the workbench 1 and its output end is fixedly connected to the first conveyor wheel 42. The second conveyor wheel 43 is rotatably mounted on the workbench 1 with its rotation axis set in the vertical direction. The belt 44 is wrapped around the circumferential outer wall of both the first conveyor wheel 42 and the second conveyor wheel 43 and is in a taut state. The first motor 41 drives the first conveyor wheel 42 to rotate, which drives the second conveyor wheel 43 through the belt 44. After the belt 44 is taut, it abuts against the outer wall of the upper plate, which can smoothly transport the upper plate to the subsequent process.

[0038] A positioning cylinder 5 is also fixed on the worktable 1. The positioning cylinder 5 is fixed vertically in the center of the worktable 1, and the piston end is connected to the positioning disk 51. The positioning disk 51 slides in the vertical direction. When the upper disk is being processed, the positioning disk 51 is inserted into the upper disk, and its outer wall rolls against the upper disk to prevent axial displacement of the upper disk.

[0039] Workflow:

[0040] Feeding stage: The upper plate is placed on the slide rail 15, the piston of the feeding cylinder 11 extends, and pushes the upper plate to move along the slide rail 15 to between the driving wheel 13 and the driven wheel 14. The displacement cylinder 141 pushes the driven wheel 14 to cooperate with the driving wheel 13 to clamp the upper plate.

[0041] Adhesion Stage: The piston of positioning cylinder 5 moves downward, positioning disc 51 is inserted into the upper disc for positioning, the second motor 131 starts and drives the drive wheel 13 to rotate, and the upper disc rotates synchronously. The manual or automatic feeding mechanism adheres the starting end of the decorative tape to the outer circumference of the upper disc. The rotation of the upper disc completes the winding of the decorative tape. In actual operation, the release end of the decorative tape is located between the upper disc and the drive wheel 13. Due to static electricity, the release end of the decorative tape will directly adhere to the drive wheel 13. After the upper disc is positioned by the drive wheel 13 and the driven wheel 14, the decorative tape can be adhered to the upper disc. The automatic feeding structure here is the unwinding device for the decorative tape.

[0042] Cutting stage: After the decorative strip is wrapped to the appropriate number of turns, the cutting cylinder 22 pushes the electric scissors 21 to move down and cut the decorative strip. The positioning cylinder 5 and the displacement cylinder 141 then reset.

[0043] Material feeding stage: The piston of the feeding cylinder 12 extends, the flipping block 32 of the clamping piece 3 clamps the inner wall of the upper plate, drags the upper plate away from the drive wheel 13, and reaches the receiving component 4. The belt 44 drives the upper plate to be conveyed to the feeding area.

[0044] The implementation principle of the device for attaching decorative strips to the upper plate of a lantern decoration according to an embodiment of this application is as follows: the feeding cylinder 11 and the unloading cylinder 12 cooperate with the slide rail 15 to complete the conveying of the upper plate; the displacement cylinder 141 drives the driven wheel 14 to cooperate with the driving wheel 13 to clamp the upper plate; the second motor 131 drives the driving wheel 13 to rotate, causing the upper plate to rotate at a uniform speed to ensure that the decorative strip is evenly wound; the positioning cylinder 5 and the positioning plate 51 prevent the upper plate from shaking and ensure the adhesion accuracy; the cutting component 2 realizes the precise cutting of the decorative strip; the receiving component 4 completes the unloading and conveying of the upper plate. The whole process does not require direct manual contact with the upper plate and the decorative strip, has a high degree of automation, and the adhesion efficiency is significantly improved compared with the traditional manual method. Moreover, it has accurate positioning and strong adaptability, which can meet the needs of mass and efficient production of decorative strips for lantern upper plates.

[0045] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
