Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment technology, specifically a flat-pressure guide structure suitable for sound-absorbing cotton bonding. Background Technology

[0002] In the production and processing of sound-absorbing cotton, the precision and flatness of the bonding process are key factors affecting product quality. Currently, some guiding structures for sound-absorbing cotton bonding have appeared on the market. These structures typically operate using rolling or lateral limiting methods. However, in practical applications, such equipment may result in unsatisfactory bonding effects due to unstable guidance or uneven pressure distribution. Furthermore, some equipment is poorly designed to adapt to sound-absorbing cotton of different thicknesses and sizes, which can easily increase production debugging time and costs.

[0003] Furthermore, many devices, due to the lack of a flat-pressure stable guiding function, may cause material misalignment or uneven surface during the bonding process.

[0004] Therefore, we have made improvements to this by proposing a flat-pressure guide structure suitable for sound-absorbing cotton bonding. Utility Model Content

[0005] The purpose of this invention is to solve the problem of unsatisfactory bonding effect caused by unstable guidance, uneven pressure distribution, and poor adaptability to sound-absorbing cotton of different thicknesses and sizes during the existing sound-absorbing cotton bonding process.

[0006] To achieve the aforementioned objectives and address the problems, this utility model provides a flat-press guide structure suitable for sound-absorbing cotton bonding, comprising a support frame, a guide assembly, and a flattening assembly. The guide assembly is installed on both sides of the support frame to limit and guide the sound-absorbing cotton; the flattening assembly is positioned above the guide assembly and works in conjunction with it to achieve a smooth bonding of the sound-absorbing cotton through horizontal pressure distribution. An adjustment mechanism is provided at the top of the support frame to adjust the height of the flattening assembly to accommodate sound-absorbing cotton of different thicknesses.

[0007] The guiding assembly includes two symmetrically arranged guide plates. Each guide plate has several guide wheels on its inner side. The guide wheels are connected to the guide plates via rotating shafts, and the outer circumferential surface of the guide wheels is provided with an elastic layer. A slider is fixedly provided at the bottom of the guide plate. The slider is embedded in a groove opened at the top of the support frame, allowing the guide plate to move horizontally along the groove. Positioning bolts are provided at both ends of the groove. The positioning bolts pass through the groove and are threadedly connected to the slider to fix the position of the guide plate.

[0008] The flattening assembly includes a pressure plate and a pressure distribution device. The bottom of the pressure plate has a flexible pad made of rubber or silicone, which directly contacts the surface of the sound-absorbing cotton and applies uniform pressure. The pressure distribution device includes multiple pressure rods and a spring assembly. One end of each pressure rod is fixedly connected to the pressure plate, and the other end passes through a through-hole in the top of the support frame and connects to an adjustment mechanism. The spring assembly is sleeved on the pressure rods and located between the pressure plate and the support frame, providing elastic cushioning.

[0009] The adjustment mechanism includes an adjusting screw and a handwheel. The adjusting screw is vertically positioned, with its top end fixedly connected to the handwheel and its bottom end passing through the top of the support frame and threadedly connected to the top of the pressure rod. Rotating the handwheel causes the adjusting screw to move the pressure rod up and down, thereby adjusting the height of the pressure plate. A scale is also provided on the top of the support frame, positioned along the axial direction of the adjusting screw, to indicate the lifting height of the pressure plate.

[0010] As a preferred technical solution of this application, the outer side of the guide plate is provided with reinforcing ribs, which are integrally formed with the guide plate to enhance the rigidity of the guide plate and prevent deformation during use. The bottom of the reinforcing ribs is fixedly connected to the slider to further improve the stability of the guide plate.

[0011] As a preferred technical solution of this application, the number of guide wheels is four, which are located at the four corners of the guide plate. The elastic layer thickness of the guide wheels is 3mm to 5mm, which can provide appropriate friction when the sound-absorbing cotton passes through, while avoiding damage to the surface of the sound-absorbing cotton.

[0012] As a preferred embodiment of this application, the slide groove has a T-shaped cross-section, and the shape of the slider matches the slide groove, ensuring that the slider can only move horizontally within the slide groove without deviation. The inner wall of the slide groove is coated with a lubricating coating to reduce frictional resistance during slider movement.

[0013] As a preferred technical solution of this application, the number of pressure rods is six, which are evenly distributed on the top of the pressure plate. The number of spring groups is the same as that of the pressure rods, and the elastic coefficient of each spring group is the same, so as to ensure that the pressure plate is subjected to uniform force when pressure is applied.

[0014] As a preferred technical solution of this application, the thickness of the flexible pad is 2mm to 4mm, and its surface is provided with anti-slip texture, which can increase the friction between the pad and the sound-absorbing cotton and prevent the sound-absorbing cotton from sliding during the bonding process.

[0015] As a preferred technical solution of this application, the surface of the adjusting screw is provided with anti-slip texture, and the outer peripheral surface of the handwheel is provided with anti-slip protrusions, so that the operator can apply sufficient torque when adjusting the height of the pressure plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] By employing a guide assembly and a flattening assembly, stable guidance and uniform pressure distribution of the sound-absorbing cotton are achieved. The guide wheels in the guide assembly contact the sound-absorbing cotton through an elastic layer, effectively reducing displacement during movement and preventing surface damage. The flexible pad and pressure distribution device in the flattening assembly work together to ensure uniform pressure on the sound-absorbing cotton during bonding, thus improving bonding quality. Furthermore, the height of the pressing plate can be flexibly adjusted via an adjustment mechanism to accommodate sound-absorbing cotton of different thicknesses, significantly improving the equipment's versatility and applicability. This invention solves the problem of unsatisfactory bonding results caused by unstable guidance and uneven pressure distribution in existing technologies, while also reducing production and debugging time and costs, demonstrating high practical value and potential for widespread application.

[0025] This utility model provides a flat-pressure guide structure suitable for sound-absorbing cotton bonding, the overall structure of which is as follows: Figure 1As shown, the device includes a support frame 1, a guide assembly, and a flattening assembly. The support frame 1, as the foundation of the entire device, has a groove 6 and a through hole at its top for mounting the guide assembly and the flattening assembly. The guide assembly consists of a guide plate 2, guide wheels 3, sliders 5, and positioning bolts 7. The guide plate 2 moves horizontally by being embedded in the groove 6 by the slider 5. Positioning bolts 7 are provided at both ends of the groove 6 to fix the position of the guide plate 2. The flattening assembly includes a flat plate 8, a flexible pad 9, a pressure rod 10, and a spring assembly 11. The flat plate 8 is connected to an adjustment mechanism via the pressure rod 10. The adjustment mechanism includes an adjustment screw 12, a handwheel 13, and a scale 14 for adjusting the height of the flat plate 8.

[0026] Combination Figure 2 The specific implementation of the guide assembly is described in detail. Guide plates 2 are symmetrically arranged on both sides of the support frame 1. Four guide wheels 3 are installed on the inner side of each guide plate 2, located at the four corners of the guide plate 2. The guide wheels 3 are connected to the guide plates 2 via rotating shafts, and the outer circumferential surface of the guide wheels 3 is covered with an elastic layer 4 with a thickness of 3mm to 5mm, made of rubber. A slider 5 is fixedly installed at the bottom of the guide plate 2. The slider 5 is embedded in a groove 6 opened at the top of the support frame 1. The groove 6 has a T-shaped cross-section. Figure 5 As shown, the shape of slider 5 matches that of groove 6, ensuring that slider 5 can only move horizontally without deviation. The inner wall of groove 6 is coated with a lubricating coating to reduce frictional resistance when slider 5 moves. Positioning bolt 7 passes through groove 6 and is threaded to slider 5; tightening positioning bolt 7 fixes the position of guide plate 2. Reinforcing rib 15 is also provided on the outer side of guide plate 2. Reinforcing rib 15 is integrally formed with guide plate 2 and fixedly connected to slider 5, thereby enhancing the rigidity of guide plate 2 and preventing deformation during use.

[0027] Combination Figure 3The specific implementation of the flattening assembly is described in detail. The flattening plate 8 is located above the guide assembly. The bottom of the flattening plate 8 has a flexible pad 9 with a thickness of 2mm to 4mm. The flexible pad 9 is made of silicone material and has an anti-slip texture on its surface to increase friction with the sound-absorbing cotton. Six pressure rods 10 are evenly distributed on the top of the flattening plate 8. One end of each pressure rod 10 is fixedly connected to the flattening plate 8, and the other end passes through a through hole in the top of the support frame 1 and is threadedly connected to the adjusting screw 12. A spring assembly 11 is sleeved on the pressure rods 10 and located between the flattening plate 8 and the support frame 1. Each spring assembly 11 has the same elastic coefficient to ensure uniform force distribution on the flattening plate 8 when pressure is applied. The adjusting screw 12 is vertically positioned, with its top end fixedly connected to a handwheel 13 and its bottom end passing through the top of the support frame 1 and threadedly connected to the top end of the pressure rod 10. When the handwheel 13 is rotated, the adjusting screw 12 moves the pressure rods 10 up and down, thereby adjusting the height of the flattening plate 8. The top of the support frame 1 is also equipped with a scale 14, which is set along the axial direction of the adjusting screw 12 to indicate the lifting height of the pressure plate 8. The surface of the adjusting screw 12 is provided with anti-slip texture, and the outer circumferential surface of the handwheel 13 is provided with anti-slip protrusions, so that the operator can apply sufficient torque when adjusting the height of the pressure plate 8.

[0028] The working process of this utility model is as follows: First, the operator adjusts the position of the guide plate 2 according to the width of the sound-absorbing cotton to be bonded. By loosening the positioning bolts 7, the slider 5 moves horizontally along the slide groove 6. After adjusting the guide plate 2 to the appropriate position, the positioning bolts 7 are tightened for fixation. Next, according to the thickness of the sound-absorbing cotton, the handwheel 13 is rotated, and the adjusting screw 12 drives the pressure rod 10 to move up and down, thereby adjusting the height of the pressure plate 8. Simultaneously, the height of the pressure plate 8 is observed through the scale 14 to ensure it matches the thickness of the sound-absorbing cotton. After completing the above preparations, the sound-absorbing cotton is placed between the guide components, with both sides of the sound-absorbing cotton contacting the elastic layer 4 of the guide wheel 3. The guide wheel 3 provides appropriate friction during the movement of the sound-absorbing cotton and avoids damage to its surface. Then, the bonding equipment is started. Under the action of the spring assembly 11, the pressure plate 8 applies uniform pressure to the sound-absorbing cotton, and the flexible pad 9 directly contacts the surface of the sound-absorbing cotton, ensuring uniform pressure distribution. During the bonding process, the guide wheel 3 rotates as the sound-absorbing cotton moves, and the guide plate 2 remains stable through the reinforcing rib 15 and the slider 5, thereby achieving a smooth bonding of the sound-absorbing cotton.

[0029] The structural design of this utility model fully considers the guiding stability, pressure distribution uniformity, and adaptability to sound-absorbing cotton of different thicknesses during the sound-absorbing cotton bonding process. The guide wheel 3 in the guiding assembly contacts the sound-absorbing cotton through the elastic layer 4, effectively reducing the offset of the sound-absorbing cotton during movement and preventing damage to its surface. The flexible pad 9 and pressure distribution device in the flattening assembly work together to ensure that the sound-absorbing cotton receives uniform pressure during bonding. The design of the adjustment mechanism allows for flexible adjustment of the height of the pressing plate 8, significantly improving the versatility and applicability of the equipment.

[0030] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0031] In the actual operation of sound-absorbing cotton bonding, the position of the guide assembly first needs to be adjusted according to the width of the sound-absorbing cotton to be processed. The operator loosens the positioning bolt 7, and the slider 5 moves horizontally along the slide groove 6, driving the guide plate 2 to adjust to a position that matches the width of the sound-absorbing cotton. During this process, the T-shaped structure of the slide groove 6 and the shape matching design of the slider 5 ensure that the guide plate 2 can only move in the horizontal direction without deviation. At the same time, the lubricating coating on the inner wall of the slide groove 6 effectively reduces the frictional resistance during movement. After adjustment, the positioning bolt 7 is tightened to fix the position of the guide plate 2. In this step, the reinforcing ribs 15 set on the outer side of the guide plate 2 enhance its rigidity and prevent deformation due to long-term use or stress, thereby ensuring the stability of the guide assembly.

[0032] Subsequently, the height of the pressing assembly is adjusted according to the thickness of the sound-absorbing cotton. The operator rotates the handwheel 13, which in turn rotates the adjusting screw 12 and drives the pressure rod 10 to move up and down, thereby adjusting the height of the pressing plate 8. The scale 14 set on the top of the support frame 1 is used to accurately indicate the lifting height of the pressing plate 8, ensuring that it matches the thickness of the sound-absorbing cotton. During this process, the anti-slip texture on the surface of the adjusting screw 12 and the anti-slip protrusions on the outer circumference of the handwheel 13 facilitate the operator to apply sufficient torque, thereby achieving precise height adjustment. After the height adjustment is completed, the pressing plate 8 applies uniform pressure to the sound-absorbing cotton through the action of the spring assembly 11. The flexible pad 9 directly contacts the surface of the sound-absorbing cotton, and its anti-slip texture increases the friction between it and the sound-absorbing cotton, further preventing the sound-absorbing cotton from slipping during the bonding process.

[0033] After placing the sound-absorbing cotton between the guide components, the bonding device is activated. The two sides of the sound-absorbing cotton contact the elastic layer 4 of the guide wheel 3. The guide wheel 3 rotates as the sound-absorbing cotton moves, providing appropriate friction to prevent damage to the surface of the cotton. The rubber elastic layer 4 covering the outer circumference of the guide wheel 3 has a certain buffering effect, reducing the deviation of the sound-absorbing cotton during movement and ensuring the stability of the guide. Simultaneously, the pressure plate 8 applies uniform pressure to the sound-absorbing cotton under the action of the spring assembly 11. The silicone material and appropriate thickness design of the flexible pad layer 9 ensure uniform pressure distribution, preventing excessive local pressure that could cause unevenness on the surface of the sound-absorbing cotton.

[0034] During the bonding process, the guiding assembly and the flattening assembly work together to ensure a smooth and even fit of the sound-absorbing cotton. The guide plate 2 is stabilized by reinforcing ribs 15 and sliders 5, preventing displacement caused by external vibrations or equipment operation. The flattening plate 8 achieves uniform pressure distribution through six evenly distributed pressure rods 10 and spring sets 11. Each spring set 11 has the same elastic coefficient, ensuring uniform force distribution on the flattening plate 8 when pressure is applied. Furthermore, the design of the adjustment mechanism allows the height of the flattening plate 8 to be flexibly adjusted according to the thickness of the sound-absorbing cotton, significantly improving the versatility and applicability of the equipment.

[0035] Through the above steps, this invention achieves dual assurance of guiding stability and uniform pressure distribution during the sound-absorbing cotton bonding process, while simultaneously solving the problem of poor adaptability to sound-absorbing cotton of different thicknesses and sizes in existing technologies. The guide wheel 3 in the guiding assembly contacts the sound-absorbing cotton through the elastic layer 4, reducing not only the offset of the sound-absorbing cotton during movement but also preventing damage to its surface. The flexible pad 9 and pressure distribution device in the flattening assembly work together to ensure that the sound-absorbing cotton receives uniform pressure during bonding, thereby improving bonding quality. The design of the adjustment mechanism allows the equipment to quickly adapt to sound-absorbing cotton of different thicknesses, reducing production and debugging time and costs, demonstrating the efficiency and practicality of this invention.
