Description

Technical Field

[0001] This utility model relates to the field of automated equipment and sound-absorbing material processing technology, and in particular to a stacking fixture for automatically lifting and lowering sound-absorbing cotton. Background Technology

[0002] Currently, in the production and processing of sound-absorbing cotton, it needs to be stacked for subsequent handling and transportation. However, due to the softness and varying thickness of the sound-absorbing cotton, it is prone to deformation or damage during stacking due to uneven stress, affecting product quality. To solve this problem, manual adjustment is usually used to arrange and stack the sound-absorbing cotton, but this method is inefficient and labor-intensive. Furthermore, to accommodate stacking at different heights, operators need to frequently adjust the height of the workbench, but most existing equipment lacks automatic lifting functions, making the adjustment process complex and time-consuming. In addition, without suitable auxiliary devices, the position of the sound-absorbing cotton is prone to shifting during stacking, further increasing the difficulty of arrangement and reducing overall work efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide a stacking fixture for sound-absorbing cotton that can automatically lift and lower, thus solving the problems mentioned in the background art.

[0004] This invention is implemented as follows: a stacking fixture for automatically lifting and lowering sound-absorbing cotton. The device mainly consists of a base, a lifting mechanism mounted on the base, a support platform mounted on top of the lifting mechanism, and a positioning component mounted on the support platform. The base serves as the basic support component of the overall structure. The lifting mechanism is fixed to the base with bolts, the support platform is connected to the lifting mechanism via a sliding rail, and the positioning component is mounted on the support platform with screws.

[0005] The lifting mechanism includes a vertically mounted column, a lead screw installed inside the column, and a power unit that drives the lead screw to rotate. The column is a rectangular tubular structure with a threaded sleeve inside that matches the lead screw. The threaded sleeve is fixed to the inner wall of the column by bearings. One end of the lead screw is connected to the output shaft of the power unit via a coupling, and the other end is fixed to the bottom of the column by a limit block. The power unit is a stepper motor, which is fixed to one side of the column by a bracket and receives external signals through a control circuit to adjust its speed and direction. When the stepper motor starts, the lead screw rotates, causing the threaded sleeve to move up and down along the inside of the column, thereby realizing the lifting function of the support platform.

[0006] The support platform includes a horizontally positioned support plate and a slider mounted below it. The support plate is a rectangular flat plate with a non-slip rubber layer on its surface to reduce friction between the sound-absorbing cotton and the support plate and prevent the cotton from slipping. The slider has a T-shaped structure and is embedded in a slide rail on the outside of the column. Low-resistance sliding between the slider and the slide rail is achieved through ball bearings. The top of the slider is fixed to the support plate with bolts, and the bottom is connected to a threaded sleeve through a threaded hole. When the lifting mechanism is working, the up-and-down movement of the threaded sleeve drives the slider to move along the slide rail, thereby raising and lowering the support plate accordingly.

[0007] The positioning assembly includes multiple limiting plates mounted on the tray and elastic pressure strips installed between the limiting plates. The limiting plates are L-shaped metal plates, fixed to the tray at the bottom with screws, and extending outwards at the top to form a retaining edge. Four limiting plates are designed according to the tray size, located at the four edges of the tray to restrict the lateral movement of the sound-absorbing cotton. The elastic pressure strips have an arc-shaped structure, with both ends connected to adjacent limiting plates via hinges. A spring plate is located in the middle, and its elasticity allows the elastic pressure strip to fit tightly against the surface of the sound-absorbing cotton. A soft silicone pad is provided on the inner side of the elastic pressure strip to prevent compression damage to the sound-absorbing cotton.

[0008] This utility model discloses an automatic lifting and lowering sound-absorbing cotton stacking fixture. The lifting mechanism allows for height adjustment of the supporting platform, solving the problems of complex and time-consuming adjustment processes in existing equipment. The anti-slip rubber layer and positioning components on the supporting platform work together to effectively reduce deformation or damage to the sound-absorbing cotton caused by uneven force during stacking. The combination design of the limiting plate and elastic pressure strip not only fixes the position of the sound-absorbing cotton but also adapts to sound-absorbing cotton of different thicknesses, improving the versatility and applicability of the device. Furthermore, the precise control of the stepper motor ensures a smooth and reliable lifting process, further improving work efficiency and reducing labor intensity. Attached Figure Description

[0013] The specific implementation method of the automatic lifting and lowering sound-absorbing cotton stacking fixture of this utility model is as follows, in conjunction with the appendix. Figure 1 To be continued Figure 3 A detailed description will be provided. The device mainly includes a base 1, a lifting mechanism, a support platform, and a positioning component. The connection relationships, positional relationships, and mutual cooperation relationships between its various components will be described in detail one by one.

[0014] The base 1, serving as the fundamental support for the entire device, is a rectangular flat plate made of high-strength steel to ensure the stability of the overall system. The four corners of the base 1 are bolted to the ground or workbench, providing stable support. The core component of the lifting mechanism is the column 2, which is vertically positioned and fixed at the center of the upper surface of the base 1. The column 2 has a rectangular tubular structure, containing a lead screw 3 and a threaded sleeve 4. The lead screw 3 penetrates the interior of the column 2 and is threaded into the threaded sleeve 4. One end of the lead screw 3 is connected to the output shaft of the stepper motor 5 via a coupling, while the other end is fixed to the bottom of the column 2 via a limit block. The stepper motor 5 is fixed to one side of the column 2 by a bracket, an L-shaped metal component, which is screwed to the outer wall of the column 2. The control circuit of the stepper motor 5 is connected to an external signal source, enabling precise adjustment of its speed and direction of rotation based on the input signal.

[0015] The support platform includes a support plate 6 and a slider 8. The support plate 6 is a horizontally arranged rectangular flat plate structure, with the slider 8 fixed to its bottom by bolts. The slider 8 has a T-shaped structure, which is embedded in the slide rail 12 on the outside of the column 2 and slides with low resistance through ball bearings. The top of the slider 8 is fixed to the support plate 6 by bolts, and the bottom is connected to the threaded sleeve 4 through a threaded hole. When the stepper motor 5 is started, the lead screw 3 begins to rotate, driving the threaded sleeve 4 to move up and down along the inside of the column 2, thereby pushing the slider 8 to move along the slide rail 12, causing the support plate 6 to rise and fall accordingly. The upper surface of the support plate 6 is covered with a layer of anti-slip rubber 7, which is fixed to the surface of the support plate 6 by adhesive to reduce the friction between the sound-absorbing cotton and the support plate 6 and prevent the sound-absorbing cotton from slipping.

[0016] The positioning assembly is installed on the upper surface of the tray 6 and mainly consists of limiting plates 9 and elastic pressure strips 10. The limiting plates 9 are L-shaped metal plates, with their bottoms fixed to the edge of the tray 6 by screws, and their tops extending outwards to form a retaining edge. There are four limiting plates 9, located at the four edges of the tray 6, used to restrict the lateral movement of the sound-absorbing cotton. The elastic pressure strip 10 has an arc-shaped structure, with both ends connected to adjacent limiting plates 9 by hinges, and a spring plate 11 in the middle. The elasticity of the spring plate 11 allows the elastic pressure strip 10 to fit tightly against the surface of the sound-absorbing cotton. A soft silicone pad is provided on the inner side of the elastic pressure strip 10 to prevent compression damage to the sound-absorbing cotton.

[0017] In actual operation, the sound-absorbing cotton is first placed on the anti-slip rubber layer 7 of the support plate 6, and its position is adjusted to fit tightly against the edge of the limiting plate 9. Then, the elastic pressure strip 10 applies inward pressure under the action of the spring sheet 11, firmly fixing the sound-absorbing cotton to the support plate 6. At this time, the operator sends a lifting command to the stepper motor 5 through an external control device. After receiving the signal, the stepper motor 5 begins to rotate, driving the lead screw 3 to rotate synchronously. The rotation of the lead screw 3 causes the threaded sleeve 4 to move up and down along the inside of the column 2, thereby pushing the slider 8 to move along the slide rail 12. The movement of the slider 8 causes the support plate 6 and the sound-absorbing cotton on it to rise and fall together, completing the height adjustment.

[0018] To further illustrate the working principle of this utility model, in conjunction with the appendix... Figure 1 To be continued Figure 3 Please provide a detailed description. (See attached document.) Figure 1 As shown, the base 1 serves as the foundation of the entire device, upon which the column 2 and stepper motor 5 are mounted. The column 2 contains a lead screw 3 and a threaded sleeve 4. The support plate 6 is connected to the column 2 via a slider 8. (See attached diagram) Figure 2 A partial sectional view of the lifting mechanism is shown, clearly revealing that the lead screw 3 is connected to the stepper motor 5 via a coupling, and the threaded sleeve 4 is fixed to the inner wall of the column 2 via bearings. The vertical movement of the threaded sleeve 4 is crucial for the lifting and lowering of the pallet 6. (Attached) Figure 3 The top view of the support platform and positioning components is shown. The distribution of the anti-slip rubber layer 7, the limiting plate 9 and the elastic pressure strip 10 on the pallet 6 is clear. The elastic pressure strip 10 is connected to the limiting plate 9 by a hinge and provides clamping force through the spring plate 11.

[0019] In practical applications, the material stacking fixture of this invention is suitable for various scenarios, such as stacking operations during the production line, warehousing management, or transportation of sound-absorbing cotton. Taking the production line as an example, after processing, the sound-absorbing cotton needs to be transferred from the production line to the stacking area. After the operator places the sound-absorbing cotton on the pallet 6, it is fixed by the limiting plate 9 and elastic pressure strip 10 of the positioning component. Then, the stepper motor 5 is started to adjust the height of the pallet 6 so that the sound-absorbing cotton is aligned with the target stacking position. Due to the precise control of the stepper motor 5, the lifting process of the pallet 6 is smooth and reliable, effectively avoiding deformation or damage to the sound-absorbing cotton caused by uneven force. In addition, the combined design of the limiting plate 9 and the elastic pressure strip 10 can adapt to sound-absorbing cotton of different thicknesses, improving the versatility and applicability of the device.

[0020] In terms of maintenance, all components of this invention are removable and replaceable. For example, when the anti-slip rubber layer 7 wears down, it can be removed from the support plate 6 by removing the adhesive and replaced with a new rubber layer. Similarly, if the spring plate 11 of the elastic pressure strip 10 fails due to fatigue, it can also be replaced by disassembling the hinge. Key components such as the stepper motor 5 and the lead screw 3 adopt standardized designs, facilitating procurement and maintenance.

[0021] This utility model achieves automated lifting and lowering during the stacking of sound-absorbing cotton through the above-mentioned structural design, solving the problems of complex and time-consuming adjustment processes in existing equipment. At the same time, through the synergistic effect of the anti-slip rubber layer 7 and the positioning components, it effectively reduces the deformation or damage of the sound-absorbing cotton caused by uneven force during stacking, thus meeting the needs of practical applications.

[0022] 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.

[0023] In the actual operation of the sound-absorbing cotton production line, the processed sound-absorbing cotton is first placed on the pallet 6. The bottom surface of the sound-absorbing cotton contacts the anti-slip rubber layer 7. The anti-slip rubber layer 7 reduces the friction between the sound-absorbing cotton and the pallet 6 through its material properties, while providing sufficient static friction to prevent the sound-absorbing cotton from sliding. At this time, the operator needs to adjust the position of the sound-absorbing cotton so that its edge is tightly against the stop edge of the limiting plate 9. As part of the positioning component, the limiting plate 9's L-shaped structure effectively restricts the lateral movement of the sound-absorbing cotton, thereby ensuring the positional stability of the sound-absorbing cotton on the pallet 6.

[0024] Subsequently, the elastic pressure strip 10 applies inward pressure under the action of the spring plate 11. The arc-shaped structure of the elastic pressure strip 10 and the soft silicone pad are tightly attached to the surface of the sound-absorbing cotton, avoiding damage to the surface of the sound-absorbing cotton due to rigid contact. The elasticity of the spring plate 11 is designed to ensure that the sound-absorbing cotton is firmly fixed without deforming or damaging it due to excessive pressure. This design is not only suitable for sound-absorbing cotton of standard thickness, but also adaptable to sound-absorbing cotton of different thicknesses, thereby improving the versatility of the device.

[0025] Once the sound-absorbing cotton is secured, the operator sends a lifting command to the stepper motor 5 via an external control device. Upon receiving the signal, the stepper motor 5 begins to rotate, and its output shaft drives the lead screw 3 to rotate synchronously via a coupling. The rotation of the lead screw 3 causes the threaded sleeve 4 to move up and down along the interior of the column 2. The movement of the threaded sleeve 4 is transmitted to the support plate 6 via the slider 8, thus achieving smooth lifting and lowering of the support plate 6 and the sound-absorbing cotton on it. The slider 8 is embedded in the slide rail 12 and slides with low resistance via ball bearings. This design significantly reduces frictional loss during lifting and lowering, improving the overall stability and reliability of operation.

[0026] During the lifting and lowering process, the precise control capability of the stepper motor 5 plays a crucial role. The stepper motor 5 adjusts its speed and direction of rotation based on the input signal, ensuring that the lifting height of the pallet 6 is accurately aligned with the target stacking position. For example, when it is necessary to transfer sound-absorbing cotton from the production line to a higher stacking area, the stepper motor 5 gradually adjusts the height of the pallet 6 to keep the sound-absorbing cotton horizontally aligned with the target position. This smooth and precise lifting and lowering process effectively avoids deformation or damage to the sound-absorbing cotton caused by uneven force.

[0027] Furthermore, once the sound-absorbing cotton has been raised to the target height, the operator can remove it from the pallet 6 manually or using automated equipment. During this process, the design of the limiting plate 9 and the elastic pressure strip 10 still functions to ensure that the sound-absorbing cotton does not shift or tip over during removal. After removal is complete, the stepper motor 5 restarts, lowering the pallet 6 to its initial position for the next round of sound-absorbing cotton stacking.

[0028] As can be seen from the above steps, the stacking fixture of this utility model can significantly improve the efficiency and quality of sound-absorbing cotton stacking in practical applications. The synergistic effect of the anti-slip rubber layer 7, the limiting plate 9, and the elastic pressure strip 10 not only solves the problem of easy slippage and displacement of sound-absorbing cotton during stacking, but also adapts to the needs of sound-absorbing cotton of different thicknesses. The cooperation of the stepper motor 5 and the lead screw 3 realizes the automation of height adjustment, greatly reducing the workload and time cost of manual adjustment. These designs together ensure that the sound-absorbing cotton is subjected to uniform force during stacking, avoiding deformation or damage caused by external forces, and meeting actual production needs.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
