Description

Technical Field

[0001] This invention relates to the field of fiber spreading technology, and more particularly to a mechanism for uniformly spreading fibers in thermoplastics. Background Technology

[0002] In the preparation process of thermoplastic composites, the uniform distribution of fibers on the surface of the thermoplastic substrate is a crucial step that determines the mechanical properties and appearance quality of the final product. A uniform distribution mechanism typically consists of a feeding system, a distribution head, and a control system. The feeding system is responsible for conveying thermoplastic granules or fibers to the distribution head at an appropriate rate. The distribution head releases the material uniformly through multiple adjustable nozzles or openings using airflow, gravity, or mechanical vibration. During this process, the control system monitors and adjusts parameters such as distribution speed, pressure, and temperature in real time using sensors to ensure uniform material distribution.

[0003] Existing technologies, such as the invention with publication number CN118061361A, disclose an automatic fiber spreading device and method for preparing UHPC, relating to the field of concrete preparation technology. The automatic fiber spreading device includes: a mixing pot with a stirring shaft inside; a torque sensor connected to the stirring shaft for acquiring the torque signal of the stirring shaft; a fiber spreading mechanism disposed above the mixing pot for spreading fibers into the mixing pot; and a controller for acquiring the stirring shaft torque based on the torque signal, and controlling the fiber spreading mechanism to operate after a preset time when the stirring shaft torque is determined to decrease from its peak value to a torque threshold. This automatic fiber spreading device and method accurately determines the timing of fiber addition based on the stirring shaft torque, thereby achieving accurate automatic fiber spreading and solving the technical problem in related technologies where inappropriate fiber spreading time reduces the performance of UHPC products.

[0004] During the operation of fiber spreaders, traditional equipment often experiences problems such as the inability to move horizontally, requiring frequent stops for inspection, uneven fiber spreading, accidental displacement of the moving plate, deviation of the fiber spreading position from the set trajectory, uneven fiber spreading, and even folding and piling of fibers. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability of traditional equipment to move horizontally and the inability to stop for inspection at any time, as well as uneven fiber distribution. The invention proposes a mechanism for uniformly distributing thermoplastic fibers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: It includes an operating table, a carrier plate on the upper surface of the operating table, a thermoplasticizer on the upper surface of the operating table, a fiber body on the upper surface of the carrier plate, and a moving device on the upper surface of the operating table. The moving device includes two slide rails, the lower surfaces of both slide rails are fixedly connected to the surface of the operating table, and the inner walls of both slide rails are slidably connected to the same moving plate. A connecting plate is fixedly connected to one side surface of the moving plate, and a fixing plate is fixedly connected to the surface of the connecting plate. A fixing rod is threaded through the surface of the fixing plate, and an auxiliary block is fixedly connected to one end surface of the fixing rod. Several positioning blocks are fixedly connected to one side surface of the slide rails, and the cross-section of the positioning blocks is conical. A fixing block is rotatably connected to one end surface of the fixing rod, and the cross-section of the fixing block is conical. The surface of the fixing block abuts against the surface of the positioning block.

[0007] The effect achieved by the above components is as follows: when it is necessary to lock the moving plate in a certain working position, tightening the fixing rod causes the pointed cone-shaped fixing block connected to its end to be inserted into the gap between the pointed cone-shaped positioning blocks on the side of the slide rail. The cone surfaces press against each other to form a self-locking mechanism, which effectively prevents accidental displacement caused by equipment vibration or external force during the spreading process.

[0008] Preferably, the lower end surface of the connecting plate is rotatably connected to two rollers, and the arc surfaces of the two rollers are slidably connected to the upper end surface of the operating table.

[0009] The aforementioned components achieve the following effects: they provide rolling support and auxiliary guidance for the connecting plate and the moving plate. The rollers transform sliding friction into rolling friction, significantly reducing the frictional resistance of the moving plate during movement, making it easier and smoother for the operator to push and pull. At the same time, the rollers provide additional load-bearing support, preventing the connecting plate from sagging due to the cantilever structure, and further improving the stability of movement and the accuracy of spreading.

[0010] Preferably, two limiting rods are fixedly connected to the surface of the fixing block, and the arc surfaces of the two limiting rods slide through the surface of the fixing plate.

[0011] The effect achieved by the above components is that the fixed block can only move back and forth in a straight line under the constraint of the limiting rod, and will not rotate with the fixed rod, thereby ensuring that the conical fixed block is always accurately inserted into the gap between the positioning blocks in the correct posture, avoiding jamming or locking failure caused by rotational misalignment.

[0012] Preferably, an auxiliary rod is fixedly connected to the surface of the movable plate, and the arc surface of the fiber body is slidably connected to the arc surface of the auxiliary rod.

[0013] The effect achieved by the above components is that the auxiliary rod can guide the fibers to maintain a constant unwinding angle and tension during the spreading process, prevent the fibers from tangling and shifting, and ensure that the fibers can be spread evenly and straight on the carrier plate or thermoplastic machine, thereby significantly improving the uniformity and continuity of fiber spreading.

[0014] Preferably, the upper surface of the operating table is provided with clamping devices at the four corners of the carrier plate. The clamping devices include locking blocks, the lower surface of which is fixedly connected to the upper surface of the operating table. The upper surface of the locking block has a sliding groove, and a clamping plate is slidably connected to the inner wall of the sliding groove. A buffer pad is fixedly connected to the surface of the clamping plate, and the surface of the buffer pad abuts against the surface of the carrier plate. A plurality of positioning grooves are provided on one side surface of the locking block. Two fixing strips are fixedly connected to one end surface of the clamping plate. The same connecting rod is fixedly connected to the surfaces of the two fixing strips. A positioning plate is rotatably connected to the arc surface of the connecting rod. The surface of the positioning plate engages with the inner wall of one of the positioning grooves. A coil spring is sleeved on the arc surface of the connecting rod, and the two ends of the coil spring are fixedly connected to the surface of the connecting rod and the surface of the positioning plate, respectively.

[0015] The above components achieve the following effects: quick, adjustable, and tool-free clamping and fixing of the carrier plate; the clamping plate moves along the sliding groove on the locking block; and the positioning plate automatically engages with the positioning grooves at different positions on the side of the locking block under the elastic force of the coil spring, thereby realizing multi-level pressure adjustment and adapting to carrier plates of different sizes.

[0016] Preferably, a buffer pad is fixedly connected to the surface of the clamping plate, and the surface of the buffer pad abuts against the surface of the carrier plate.

[0017] The above-mentioned components achieve the following effects: they enable flexible contact between the clamping plate and the carrier plate, can elastically absorb clamping force, avoid rigid clamping from causing indentations, scratches or deformation damage to the surface of the carrier plate, effectively prevent the carrier plate from sliding due to vibration during the spreading process, and further improve the reliability and safety of clamping.

[0018] Preferably, a limiting plate is fixedly connected to the upper surface of the operating table at the positions corresponding to both ends of the locking block, and the surface of the clamping plate abuts against the surface of the limiting plate.

[0019] The effects achieved by the above components are as follows: they achieve precise constraint on the direction of movement of the clamping plate, limit the lateral sway of the clamping plate during the sliding process, ensure that the clamping plate always moves closer to or further away from the carrier plate in a straight line, and avoid jamming, tilting or clamping force deviation caused by uneven force, thereby improving the operational stability and positioning accuracy of the clamping device.

[0020] Preferably, a fixing device is provided on the upper surface of the movable plate corresponding to the position of the thermoplastic machine. The fixing device includes two stop blocks. The lower surface of each of the two stop blocks is fixedly connected to the upper surface of the movable plate. A fixing groove is formed on the upper surface of each of the two stop blocks. A slider is slidably connected to the inner wall of the fixing groove. A positioning plate is fixedly connected to one end surface of the slider. The positioning plate has an "L" shaped cross section. The surface of the positioning plate abuts against the surface of the thermoplastic machine. A positioning groove is formed on the upper surface of the slider. A positioning rod is fixedly connected to the inner wall of the fixing groove. The arc surface of the positioning rod is slidably connected to the inner wall of the positioning groove. A limit block is threadedly connected to the arc surface of the positioning rod.

[0021] The effect achieved by the above components is that the slider can slide freely in the fixed groove at the upper end of the stop block, thereby driving the L-shaped positioning plate to move, so that the surface of the positioning plate abuts against the thermoforming machine, so as to adjust its installation position to adapt to the thermoforming machine of the corresponding specification.

[0022] Preferably, a plurality of support plates are fixedly connected to the surface of the movable plate, and the lower end surface of the thermoplastic machine abuts against the surfaces of the plurality of support plates.

[0023] The effect achieved by the above components is that by fixing several support plates to the surface of the moving plate and making the lower surface of the thermoplastic machine abut against the surface of the several support plates, a stable and flat support surface is provided for the thermoplastic machine.

[0024] Preferably, the arc surface of the locking rod is fitted with an anti-slip ring, and the surface of the limiting block abuts against the surface of the anti-slip ring.

[0025] The aforementioned components achieve the following effects: they enhance the anti-loosening effect of the locking state of the limit block, the anti-slip ring plays a buffering role, and prevent direct rigid contact between the metal parts of the limit block and the slider from causing wear or seizing, thereby improving the locking reliability and service life of the fixing device.

[0026] Compared with the prior art, the advantages and positive effects of the present invention are as follows: 1. In this invention, by setting up a moving device, during operation, the moving plate slides smoothly along the inner wall of the slide rail, driving the fiber body above it to adjust the spreading position. When it is necessary to precisely lock the moving plate in a certain working position, simply tighten the fixing rod, and the pointed cone-shaped fixing block rotatably connected to its end will insert into the gap between adjacent positioning blocks, with the cone surfaces pressing against each other to form a self-locking mechanism. This cone-shaped self-locking structure utilizes the principle of inclined plane force amplification, so even if subjected to equipment vibration or external force pulling, the fixing block is difficult to detach on its own, thereby effectively preventing accidental displacement of the moving plate during spreading and significantly improving the positional stability and repeatability of fiber spreading. At the same time, two rollers are fixed to the lower surface of the connecting plate, and the arc surface of the rollers is slidably connected to the upper surface of the operating table. The rollers transform the original sliding friction into rolling friction, greatly reducing the frictional resistance when the moving plate moves, making it easier and smoother for the operator to push and pull the moving plate; at the same time, the rollers provide additional load-bearing support, preventing the connecting plate from sagging and deforming due to the cantilever structure during long-term use, further improving the stability of movement and spreading accuracy. In addition, two limiting rods are fixed to the surface of the fixing block, and the arc surfaces of the two limiting rods slide through the surface of the fixing plate. The constraint effect of the limiting rods ensures that the fixing block can only move back and forth in a straight line, and will not rotate with the fixing rods. This ensures that the conical fixing block is always accurately inserted into the gap between the positioning blocks in the correct posture, avoiding jamming or locking failure caused by rotational misalignment. An auxiliary rod is also fixed to the surface of the moving plate, and the arc surface of the fiber body slides in connection with the arc surface of the auxiliary rod. The auxiliary rod guides the fiber to maintain a constant unwinding angle and tension during the spreading process, preventing fiber entanglement and deviation, and ensuring that the fiber is spread evenly and straight on the carrier plate or thermoplastic machine, thereby significantly improving the uniformity and continuity of fiber spreading.

[0027] 2. In this invention, by setting up a clamping device, the clamping plate is pushed so that the buffer pad on its surface abuts against the side of the carrier plate. At the same time, the positioning plate automatically engages with one of the multiple positioning slots opened on the side of the clamping block under the elastic force of the coil spring, thereby achieving fast, tool-free, and multi-level adjustable clamping and fixing. Since the positioning slots are distributed in multiple positions along the side of the clamping block, the operator only needs to move the positioning plate away from the current positioning slot, move the clamping plate to the appropriate position, and release it. The positioning plate will then automatically engage with the corresponding positioning slot, easily adapting to carrier plates of different sizes. The loading and unloading efficiency is far higher than that of traditional bolt clamping methods. A buffer pad is fixed on the surface of the clamping plate, and the buffer pad flexibly abuts against the surface of the carrier plate. The buffer pad is made of elastic material, which can absorb the rigid impact in the clamping force, avoiding indentation, scratches, or local deformation damage to the surface of the carrier plate caused by direct metal or hard plastic clamping. At the same time, the elastic clamping increases the coefficient of friction, effectively preventing the carrier plate from sliding displacement due to equipment vibration during the spreading process, further improving the reliability and safety of clamping. Limiting plates are fixed to both ends of the clamping block on the upper surface of the operating table, and the surface of the clamping plate abuts against the surface of the limiting plate. The limiting plate precisely constrains the movement endpoint of the clamping plate, preventing it from disengaging from the inner wall of the sliding groove, avoiding jamming, tilting, or clamping force deviation caused by uneven force, thereby improving the operational stability and positioning accuracy of the clamping device.

[0028] 3. In this invention, by setting a fixing device, the thermoforming machine is first placed on the slider, and then the slider is slid along the fixing groove to adjust the installation position of the thermoforming machine. After the position is determined, the limiting block is tightened, which drives the L-shaped clamping plate to move, so that the surface of the clamping plate abuts against the thermoforming machine to adapt to the installation position of the thermoforming machine of the corresponding specification. This structure realizes the adjustable and detachable fixing of the thermoforming machine, and also facilitates the disassembly, maintenance or replacement of the thermoforming machine after long-term use. Several support plates are fixed on the surface of the moving plate, and the lower surface of the thermoforming machine abuts against the surface of the support plate. The support plate provides a stable and flat support surface for the thermoforming machine, avoiding tilting or shaking of the thermoforming machine due to suspension or only relying on the slider for support, and further enhancing the posture stability of the thermoforming machine during operation. The arc surface of the clamping rod is also fitted with an anti-slip ring, and the surface of the limiting block abuts against the surface of the anti-slip ring. Anti-slip rings are typically made of rubber or elastic, wear-resistant materials, serving multiple functions: first, increasing the coefficient of friction to prevent the limit block from loosening due to equipment vibration; second, acting as a buffer to avoid direct rigid contact and wear between the metal parts of the limit block and the slider; and third, providing a flexible locking feel to prevent over-tightening and thread damage. The use of anti-slip rings significantly improves the locking reliability and service life of the fixing device. It solves problems such as the inability to adjust the installation position on the moving plate of the thermoplastic machine, difficulty in disassembly, and easy loosening of the lock, allowing the thermoplastic machine to be flexibly positioned according to the fiber spreading path, while ensuring positional stability and ease of maintenance during long-term operation.

Detailed Implementation

[0031] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0032] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0033] like Figure 1 and Figure 10 As shown, the present invention provides a fiber uniform spreading mechanism for thermoplastic plastics, including an operating table 1, a carrier plate 2 disposed on the upper surface of the operating table 1, a thermoplastic machine 3 disposed on the upper surface of the operating table 1, a fiber body 7 disposed on the upper surface of the carrier plate 2, a moving device 4 disposed on the upper surface of the operating table 1, clamping devices 5 disposed on the four corners of the upper surface of the operating table 1 corresponding to the carrier plate 2, and a fixing device 6 disposed on the upper surface of the moving plate 402 corresponding to the position of the thermoplastic machine 3.

[0034] The following section will describe in detail the specific configuration and function of its moving device 4, clamping device 5, and fixing device 6.

[0035] like Figure 2 , Figure 3 and Figure 4As shown, the moving device 4 includes two slide rails 401. The lower surfaces of both slide rails 401 are fixedly connected to the surface of the operating table 1. The inner walls of both slide rails 401 are slidably connected to the same moving plate 402. A connecting plate 403 is fixedly connected to one side surface of the moving plate 402. A fixing plate 405 is fixedly connected to the surface of the connecting plate 403. A fixing rod 406 is threaded through the surface of the fixing plate 405. An auxiliary block 407 is fixedly connected to one end surface of the fixing rod 406. Several positioning blocks 411 are fixedly connected to one side surface of the slide rails 401. The cross-section of the positioning blocks 411 is conical. A fixing block 408 is rotatably connected to one end surface of the fixing rod 406. The cross-section of the fixing block 408 is conical. The surface of the fixing block 408 abuts against the surface of the positioning block 411. When it is necessary to lock the movable plate 402 in a certain working position, tightening the fixing rod 406 causes the pointed conical fixing block 408 connected to its rotatable end to insert into the gap between the pointed conical positioning blocks 411 on the side of the slide rail 401. The conical surfaces abut against each other to form a self-locking mechanism, effectively preventing accidental displacement caused by equipment vibration or external pulling during the spreading process. Two rollers 404 are rotatably connected to the lower surface of the connecting plate 403, and the arc surfaces of the two rollers 404 are slidably connected to the upper surface of the operating table 1. This achieves rolling support and auxiliary guidance for the connecting plate 403 and the movable plate 402. The rollers 404 convert sliding friction into rolling friction, which greatly reduces the frictional resistance when the movable plate 402 moves, making it easier and smoother for the operator to push and pull. At the same time, the rollers 404 provide additional load-bearing support, preventing the connecting plate 403 from sagging due to the cantilever structure, further improving the stability of movement and spreading accuracy. Two limiting rods 409 are fixedly connected to the surface of the fixing block 408, and the arc surfaces of the two limiting rods 409 slide through the surface of the fixing plate 405. Under the constraint of the limiting rods 409, the fixing block 408 can only move back and forth in a straight line and will not rotate with the fixing rods 406, thus ensuring that the conical fixing block 408 is always accurately inserted into the gap between the positioning blocks 411 in the correct posture, avoiding jamming or locking failure caused by rotational misalignment. An auxiliary rod 410 is fixedly connected to the surface of the moving plate 402, and the arc surface of the fiber body 7 slides in connection with the arc surface of the auxiliary rod 410. The auxiliary rod 410 can guide the fiber to maintain a constant unwinding angle and tension during the spreading process, prevent the fiber from tangling and shifting, and ensure that the fiber can be spread evenly and straight on the carrier plate 2 or thermoplastic machine 3, thereby significantly improving the uniformity and continuity of fiber spreading.

[0036] like Figure 5 and Figure 6As shown, the clamping device 5 includes a locking block 501. The lower surface of the locking block 501 is fixedly connected to the upper surface of the operating table 1. A sliding groove 502 is provided on the upper surface of the locking block 501. A clamping plate 503 is slidably connected to the inner wall of the sliding groove 502. A buffer pad 504 is fixedly connected to the surface of the clamping plate 503. The surface of the buffer pad 504 abuts against the surface of the carrier plate 2. Several positioning grooves 506 are provided on one side surface of the locking block 501. Two fixing strips 507 are fixedly connected to one end surface of the clamping plate 503. The same connecting rod 508 is fixedly connected to the surface of the two fixing strips 507. A positioning plate 510 is rotatably connected to the arc surface of the connecting rod 508. The surface of the positioning plate 510 is engaged with the inner wall of one of the positioning grooves 506. A coil spring 509 is sleeved on the arc surface of the connecting rod 508. The two ends of the coil spring 509 are fixedly connected to the surface of the connecting rod 508 and the surface of the positioning plate 510, respectively. The clamping and fixing of the carrier plate 2 is quick, adjustable, and tool-free. The clamping plate 503 moves along the sliding groove 502 on the positioning block 501, and the positioning plate 510 automatically engages with the positioning grooves 506 at different positions on the side of the positioning block 501 under the elastic force of the coil spring 509, thereby achieving multi-level pressure adjustment to accommodate carrier plates 2 of different sizes. A buffer pad 504 is fixedly connected to the surface of the clamping plate 503, and the surface of the buffer pad 504 abuts against the surface of the carrier plate 2. This achieves flexible contact between the clamping plate 503 and the carrier plate 2, which can elastically absorb clamping force and avoid rigid clamping from causing indentations, scratches, or deformation damage to the surface of the carrier plate 2. It effectively prevents the carrier plate 2 from sliding due to vibration during the spreading process, further improving the reliability and safety of clamping. Limiting plates 505 are fixedly connected to the upper surface of the operating table 1 at the positions corresponding to both ends of the positioning block 501, and the surface of the clamping plate 503 abuts against the surface of the limiting plate 505. It achieves precise constraint on the movement direction of the clamping plate 503, restricts the lateral sway of the clamping plate 503 during the sliding process, and ensures that the clamping plate 503 always moves closer to or away from the carrier plate 2 in a straight line, avoiding jamming, tilting or clamping force deviation caused by uneven force, thereby improving the operational stability and positioning accuracy of the clamping device 5.

[0037] like Figure 7 , Figure 8 and Figure 9As shown, a fixing device 6 is provided on the upper surface of the movable plate 402 corresponding to the position of the thermoplastic machine 3. The fixing device 6 includes two stop blocks 62. The lower surface of the two stop blocks 62 is fixedly connected to the upper surface of the movable plate 402. The upper surface of the two stop blocks 62 is provided with a fixing groove 63. A slider 64 is slidably connected to the inner wall of the fixing groove 63. A positioning plate 64 is fixedly connected to one end surface of the slider 64. The positioning plate 64 has an "L" shaped cross section. The surface of the positioning plate 64 abuts against the surface of the thermoplastic machine 3. A positioning groove 66 is provided on the upper surface of the slider 64. A positioning rod 67 is fixedly connected to the inner wall of the fixing groove 63. The arc surface of the positioning rod 67 is slidably connected to the inner wall of the positioning groove 66. A limit block 68 is threadedly connected to the arc surface of the positioning rod 67. The thermoforming machine 3, after prolonged use, is adjustable and detachable on the moving plate 402. The slider 64 slides within the fixing groove 63 at the upper end of the stop block 62, thereby adjusting the installation position of the thermoforming machine 3. The locking rod 67 passes through the locking groove 66 at the upper end of the slider 64, and the slider 64 pushes the locking plate 65, which abuts against the thermoforming machine 3, thus fixing the thermoforming machine 3. Several support plates 61 are fixedly connected to the surface of the moving plate 402, and the lower surface of the thermoforming machine 3 abuts against the surfaces of the support plates 61. By fixing several support plates 61 to the surface of the moving plate 402 and ensuring that the lower surface of the thermoforming machine 3 abuts against the surfaces of the support plates 61, a stable and flat support surface is provided for the thermoforming machine 3. An anti-slip ring 69 is fitted onto the arc surface of the locking rod 67, and the surface of the limiting block 68 abuts against the surface of the anti-slip ring 69. The locking state of the limit block 68 is enhanced to prevent loosening, and the anti-slip ring 69 plays a buffering role, avoiding direct rigid contact between the metal parts of the limit block 68 and the slider 64, which would cause wear or seizing, thus improving the locking reliability and service life of the fixing device 6.

[0038] The overall working principle is as follows: First, the thermoplastic machine 3 is fixed inside the moving plate 402. Then, the carrier plate 2 is placed stably above the operating table 1. After completion, the thermoplastic machine 3 is started to evenly spread thermoplastic plastic fibers onto the carrier plate 2. The operator pushes the moving plate 402 to slide back and forth along the inner wall of the two slide rails 401 fixed at the upper end of the operating table 1. The moving plate 402 drives the connecting plate 403 and the fixed plate 405 to move synchronously. The two rollers 404 at the lower end of the connecting plate 403 roll on the upper surface of the operating table 1, converting sliding friction into rolling friction to reduce resistance and support the cantilever structure. When the moving plate 402 moves, the operator pushes the moving plate 402 to slide back and forth along the inner wall of the two slide rails 401 fixed at the upper end of the operating table 1. 2. When it is necessary to lock the fiber at a precise spreading position, tighten the fixing rod 406 on the fixing plate 405. The pointed cone-shaped fixing block 408 connected to the end of the fixing rod 406 can only move in a straight line and will not rotate under the constraint of the limiting rods 409 on both sides. This allows it to be accurately inserted into the gap between the multiple positioning blocks 411 that are pointed cone-shaped on the side of the slide rail 401. The cone surfaces press against each other to form a self-locking mechanism, preventing displacement due to vibration or external force. At the same time, the auxiliary rod 410 on the moving plate 402 slides and engages with the arc surface of the fiber body 7, guiding the fiber to maintain a constant unwinding angle and tension, preventing entanglement and deviation, and achieving uniform and straight spreading. The clamping block 501 is fixed on the operating table 1. The clamping plate 503 moves along the sliding groove 502 on the clamping block 501, so that the buffer pad 504 on the surface of the clamping plate 503 abuts against the side of the carrier plate 2. The clamping plate 503 is connected to the positioning plate 510 through the fixing strip 507 and the connecting rod 508. A coil spring 509 is sleeved on the connecting rod 508. The two ends of the coil spring 509 are connected to the rod 508 and the positioning plate 510 respectively. Under the elastic force of the coil spring 509, the positioning plate 510 automatically engages with the corresponding position in the multiple positioning grooves 506 on the side of the clamping block 501, realizing tool-free, rapid, multi-level adjustment of clamping force. The buffer pad 504 elastically absorbs rigid impacts to avoid damaging the carrier plate 2. The limiting plates 505 at both ends of the clamping block 501 abut against the sides of the clamping plate 503 to limit its lateral swing and ensure that the clamping plate 503 always moves in a straight line, thereby stably clamping carrier plates 2 of different sizes. Two stop blocks 62 are fixed on the upper surface of the moving plate 402 corresponding to the position of the thermoforming machine 3. The upper end of the stop block 62 has a fixing groove 63, and the slider 64 is slidably connected in the fixing groove 63. The slider 64 pushes the positioning plate 65, and the positioning plate 65 abuts against the thermoforming machine 3. The upper end of the slider 64 has a positioning groove 66, and the positioning rod 67 fixed on the inner wall of the fixing groove 63 passes through the positioning groove 66 and slides with it. The thermoforming machine 3 forms a stable support surface. The position of the thermoforming machine 3 can be adjusted by sliding the slider 64 along the fixing groove 63. After it is in place, the limiting block 68 on the positioning rod 67 is tightened. The limiting block 68 presses the upper surface of the slider 64 to lock it. The anti-slip ring 69 sleeved on the positioning rod 67 is located between the limiting block 68 and the slider 64. When the limiting block 68 is tightened, the anti-slip ring 69 is compressed, which increases the friction to prevent vibration and loosening, and at the same time avoids metal rigid contact that may cause wear or seizing.
