Description

Technical Field

[0001] This utility model relates to the field of orthotics technology, specifically to a cardboard warping corrector. Background Technology

[0002] During production, storage, or use, cardboard often warps due to changes in humidity, temperature, or external forces, severely affecting its subsequent processing and performance. To address this issue, various cardboard warping correction devices have emerged in the prior art, typically including a placement groove for supporting the cardboard and a clamping assembly mounted on it. After the user places the cardboard in the groove, pressure is applied by the clamping structure, and the pressure is maintained for a certain period of time to achieve initial leveling.

[0003] However, these traditional orthodontic appliances still have significant shortcomings in practical use:

[0004] 1. The operation process is cumbersome. Before straightening, the warped part of the cardboard needs to be manually flattened before the clamping component is activated to fix it. This is not only inefficient, but also depends on the experience of the operator, which increases the complexity of use.

[0005] 2. Common clamping components often adopt a simple downward pressing structure, which lacks an effective guiding and balancing mechanism during vertical movement. This can easily lead to skewing or shaking, resulting in uneven pressure distribution, affecting the consistency and stability of the correction effect, and may even cause damage to the cardboard due to local overpressure.

[0006] Therefore, in view of this, an improvement was made to the existing structure, and a cardboard warping corrector was proposed. Utility Model Content

[0007] The technical problem this invention aims to solve is that the warped parts of the cardboard need to be manually flattened beforehand, and the pressing component is not stable enough when it moves downwards.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a cardboard warping corrector, including a placement groove, a pressing component disposed in the placement groove, two sliding grooves disposed on the placement groove, the pressing component including a sliding plate disposed in the sliding groove, a height adjustment structure for adjusting the height of the two sliding plates disposed on the placement groove, a connecting plate fixedly disposed between the two sliding plates and slidably connected to the placement groove, two pressure plates movably disposed at the bottom of the connecting plate, a driving component disposed in the connecting plate, and the driving component controlling the two pressure plates to move in opposite directions, thereby flattening the warped part of the cardboard;

[0009] A cooling plate is fixedly installed on the top of the placement slot, and a heating block is fixedly installed inside the pressure plate.

[0010] As a further embodiment of this utility model: the height adjustment structure includes a toothed plate fixedly installed on one side of the slide plate, two receiving plates fixedly installed on the top of the placement groove, a rotating rod rotatably passing through the two receiving plates, gears fixedly installed at both ends of the rotating rod, and the gears meshing with the corresponding toothed plates, an L-shaped rod fixedly installed on one side of the placement groove, and a motor for driving one of the gears to rotate fixedly installed on the L-shaped rod.

[0011] As a further embodiment of this utility model: the driving assembly includes an adjustment groove disposed in the connecting plate, and a bidirectional threaded rod is rotatably disposed in the adjustment groove. Two adjustment blocks are threadedly sleeved on the bidirectional threaded rod, and the adjustment blocks are slidably connected to the adjustment groove. The adjustment blocks are fixedly connected to the pressure plate, and a second motor for driving the bidirectional threaded rod to rotate is fixedly disposed on one side of one of the toothed plates.

[0012] As a further embodiment of this utility model: the cooling plate is a semiconductor refrigeration chip, and the heating block is an electric heating tube or a resistance heating chip.

[0013] As a further aspect of this utility model, it also includes a controller, which is electrically connected to the cooling plate and the heating block, and is used to control their power-on start / stop and operating power.

[0014] As a further embodiment of this utility model, a rubber pad is fixedly provided at the bottom of the placement groove.

[0015] Compared with the prior art, the advantages of this utility model are as follows:

[0016] 1. This utility model automatically controls two pressure plates to move in opposite directions through a specially designed drive component. The drive component operates before or simultaneously with the pressing component, driving the two pressure plates to move from the center to both sides, like a "smoothing" motion, automatically forcibly flattening the warped parts of the cardboard. This completely eliminates the tedious manual pre-flattening step required in traditional methods, greatly simplifying the operation process, reducing reliance on operator skills, and significantly improving correction efficiency and consistency.

[0017] 2. The clamping assembly of this invention slides between a sliding plate and a groove on the placement slot, and is driven to move up and down by a height adjustment structure (such as a gear-rack mechanism). This design provides precise guidance and solid support for the up-and-down movement of the clamping assembly, making its operation extremely smooth and effectively avoiding problems such as shaking and skewing that may occur when the clamping component presses down in traditional equipment. Stable vertical movement ensures that pressure is applied evenly to the cardboard surface, thereby greatly improving the stability and reliability of the correction and avoiding secondary damage or correction failure caused by uneven pressure.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4A cardboard warping corrector includes a placement groove 1 for supporting the cardboard to be corrected. A rubber pad is fixedly installed at the bottom of the placement groove 1 to increase friction and prevent the cardboard from sliding during the correction process, while also providing cushioning protection. A pressing component 2 is installed inside the placement groove 1. The placement groove 1 has two sliding grooves 101. The pressing component 2 includes a sliding plate 201 slidably installed in the sliding groove 101. The placement groove 1 has a height adjustment structure 3 for adjusting the height of the two sliding plates 201. The height adjustment structure 3 includes a toothed plate 301 fixedly installed on one side of the sliding plate 201. Two receiving plates 302 are fixedly installed at the top of the placement groove 1. A rotating rod 303 is rotatably connected between the two receiving plates 302. Gears 304 are fixedly installed at both ends of the rotating rod 303, and the gears 304 are meshed with the corresponding toothed plates 301. An L-shaped rod 305 is fixedly installed on one side of the placement groove 1. A motor 306 for driving one of the gears 304 to rotate is fixedly installed on the L-shaped rod 305. The output shaft of motor 306 is directly connected to one end of rotating rod 303 (or one of the gears 304) via a coupling or reduction mechanism. Starting motor 306 to rotate forward or in reverse will drive rotating rod 303 to rotate, thereby driving the gears 304 at both ends to rotate synchronously. Through the meshing of gears 304 and toothed plate 301, the entire pressing assembly 2 can be precisely controlled to rise or fall smoothly along slide groove 101.

[0027] Please see Figure 1-3 A connecting plate 202 is fixedly installed between the two sliding plates 201, and the connecting plate 202 is slidably connected to the placement groove 1, ensuring the stability and balance of the entire pressing assembly 2 during lifting and lowering, and effectively preventing it from deflecting or jamming. Two pressure plates 203 are movably installed at the bottom of the connecting plate 202. A drive assembly 4 is installed inside the connecting plate 202, and the drive assembly 4 controls the two pressure plates 203 to move in opposite directions, thereby flattening the warped part of the cardboard. The drive assembly 4 includes an adjustment groove installed in the connecting plate 202, and a bidirectional threaded rod 401 is rotatably installed in the adjustment groove. The two sections of the bidirectional threaded rod 401 have opposite threads. Two adjusting blocks 402 are respectively threaded onto the two sections of the bidirectional threaded rod 401, and the shape of the adjusting blocks 402 matches the adjustment groove, so that they can only slide horizontally in the groove and cannot rotate. The adjusting blocks 402 are fixedly connected to the pressure plates 203. A motor 403 for driving the bidirectional threaded rod 401 to rotate is fixedly installed on one side of one of the toothed plates 301. The output shaft of motor 403 is connected to one end of the bidirectional threaded rod 401 via a coupling. Starting motor 403 drives the bidirectional threaded rod 401 to rotate, thereby causing the two adjusting blocks 402 to move the two pressure plates 203 closer or further apart in the horizontal direction, achieving the action of "flattening" or "opening".

[0028] Please see Figure 1-3A cooling plate 5 is fixedly installed on the top of the placement slot 1, and a heating block is fixedly installed inside the pressure plate 203. The cooling plate 5 is a semiconductor cooling chip, and the heating block is an electric heating tube or a resistance heating element, used for local heating of the cardboard. A controller is also included, which can be a PLC or a microcontroller control system. The controller is electrically connected to the cooling plate 5 and the heating block, and is used to control their power-on start / stop and operating power. The controller is used to programmatically control the start / stop, direction, and running time of each motor, as well as control the heating power and temperature of the heating block, and control the start / stop and cooling power of the cooling plate 5, thereby realizing an automated operation process.

[0029] The working principle of this utility model:

[0030] 1. Place the cardboard: Lay the warped cardboard flat at the bottom of placement slot 1.

[0031] 2. Flattening the warped part: The controller first starts the motor 402, which drives the bidirectional threaded rod 401 to rotate, so that the two pressure plates 203 move towards each other according to the warping direction of the cardboard (for example, if the middle is arched, it is pushed from the middle to both sides), and mechanically flatten the warped part.

[0032] 3. Pressing and Shaping: Subsequently, the controller starts motor 306, driving the pressing assembly 2 to descend as a whole, so that the two pressure plates 203 press the cardboard.

[0033] 4. Heat and cold treatment: Under the pressure state, the controller activates the heating block 7 inside the pressure plate 203 to heat and soften the warped area of ​​the cardboard; after continuous pressure for a period of time, the heating is stopped, and the top cooling plate 5 is activated to force the cardboard to cool and shape.

[0034] 5. Reset: Finally, the controller controls motor 306 to reverse, lifting the clamping assembly 2, and then controls motor 403 to reverse, causing the two pressure plates 203 to reset and open, so that the corrected cardboard can be taken out.

[0035] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
