Description

Technical Field

[0001] This invention relates to the field of silk cake weighing, specifically to a silk cake weighing stabilizing device. Background Technology

[0002] In the production process of industries such as chemical fiber and textile, yarn cake is a core intermediate product. Its weight accuracy directly affects the quality stability of subsequent weaving, dyeing and other processes. It is also a key indicator for controlling product qualification rate and optimizing raw material consumption. Therefore, during the production process of yarn cake, it is necessary to use a weighing device to detect the weight of each batch of yarn cake to ensure that the product meets the preset standards. Currently, the commonly used silk cake weighing devices in the industry are mostly composed of weighing sensors, a bearing platform, a signal transmission module, and a display control unit. In order to improve detection efficiency, some large-scale production lines will also set up multiple parallel weighing components to achieve simultaneous weighing of multiple silk cakes. These traditional weighing devices can meet the accuracy requirements in the initial use, but they are prone to accuracy deviation problems under long-term continuous operation. Accuracy deviations arise from multiple factors: on the one hand, the load cells bear the load of the yarn cake for a long time, which makes them prone to elastic fatigue and component wear, resulting in drift in sensing sensitivity; on the other hand, temperature fluctuations, vibration interference, and dust adhesion in the production environment will further aggravate the performance degradation of the weighing components; especially in scenarios with multiple weighing components, the degree of degradation of each component is different, and the deviations will be superimposed, resulting in a sharp drop in overall weighing accuracy, and this problem becomes more and more obvious with the extension of the usage time. In existing technologies, to address the aforementioned accuracy deviations, workers typically perform periodic manual inspection and calibration. This involves pausing production or during production breaks to verify and adjust the accuracy of each weighing component using standard weights. However, this method has significant drawbacks: manual inspection is time-consuming and labor-intensive, reducing the overall efficiency of the production line and increasing labor costs; within the inspection interval, the weighing device may have already developed accuracy deviations, leading to the outflow of defective products and increasing rework and raw material loss costs; furthermore, the accuracy of manual calibration is affected by operational experience, resulting in subjective errors and making it impossible to guarantee the consistency of calibration accuracy.

[0003] In summary, existing silk cake weighing devices struggle to avoid accuracy deviations under prolonged use and with multiple weighing components. Furthermore, the calibration method relying on manual periodic checks suffers from low efficiency and poor reliability, failing to meet the demands of large-scale production for accurate and stable weighing and production continuity. Therefore, there is an urgent need for a silk cake weighing stabilization device that can automatically perform accuracy self-checks, requires no manual intervention, and effectively prevent accuracy deviations, thus overcoming the shortcomings of existing technologies. Summary of the Invention

[0004] The purpose of this invention is to provide a stabilizing device for weighing silk cakes, so as to solve the problems mentioned in the background art.

[0005] A stabilizing device for weighing silk cakes includes a support base, a support housing slidably mounted on the upper surface of the support base, a movable bracket slidably mounted inside the support housing, and a plurality of weighing components for weighing silk cakes mounted on the movable bracket. The weighing component includes a support base plate, a support platform on the movable bracket, a weighing device on the lower surface of the support base plate, the weighing device being fixedly mounted on the support platform, a rotating bracket on one side of the support base plate, a rotating base rotatably mounted on the rotating bracket, the rotating base being fixedly mounted on the inner side wall of the support housing, an upper support arm fixedly mounted on the upper end of the rotating bracket near the support base plate, a measuring weight being slidably mounted on the end of the upper support arm near the support base plate, a lower support arm fixedly mounted on the lower end of the rotating bracket near the support base plate, the lower support arm being located above the support platform, and a limit bracket fixedly mounted on the side of the rotating base near the rotating bracket.

[0006] Furthermore, a bellows component is installed at the upper inner end of the support housing. The bellows component includes an upper connecting support and a lower connecting support below the upper connecting support. The upper connecting support is fixedly installed on the upper inner surface of the support housing, and the lower connecting support is fixedly installed on the top of the movable bracket. A corrugated pipe is fixedly connected between the upper connecting support and the lower connecting support. Two ventilation pipes are fixedly installed inside the movable bracket, and two valve components corresponding to the ventilation pipes are fixedly installed on the lower connecting support.

[0007] Furthermore, the valve component includes a connecting pipe, which is fixedly installed on a lower connecting support. A first communication port is opened in the middle of the connecting pipe. A first sealing plate is slidably installed below the valve component. Multiple sealing springs are fixedly connected between the first sealing plate and the connecting pipe. A second sealing plate is slidably installed in the middle of the upper surface of the first sealing plate. A second communication port is opened in the middle of the first sealing plate.

[0008] Furthermore, an L-shaped lifting rod for lifting the silk cake is fixedly installed on the upper surface of the support plate away from the rotating base, and a limiting baffle for restricting the position of the silk cake is fixedly installed on the L-shaped lifting rod.

[0009] Furthermore, multiple evenly distributed sliding brackets are fixedly installed on both sides of the support base plate, and a sliding support rod is slidably engaged in the middle of the sliding bracket, and the sliding support rod is fixedly installed on the movable bracket.

[0010] Furthermore, multiple sets of evenly distributed air blowing pipes are fixedly installed on the ventilation pipe, with two in each set, and the open end of the air blowing pipe faces the weighing component.

[0011] Furthermore, multiple sets of evenly distributed transmission gears are rotatably installed inside the support housing, with four gears in each set. Each set of transmission gears is connected by a transmission chain, and a connecting block is fixedly installed on the transmission chain. The connecting block is fixedly connected to the movable bracket.

[0012] Furthermore, multiple drive motors are fixedly mounted on the outside of the transmission gear, and the drive ends of the drive motors are fixedly mounted in the middle of the corresponding transmission gears. Multiple drive cylinders for pushing the support housing to move are fixedly mounted on the support base.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. This device, by setting up an upper support arm and measuring weights, can perform self-checks when the silk cake is not being weighed. Because there are multiple weighing components, if there is an accuracy deviation in a certain place, the problem can be quickly located through self-checks, ensuring that the weighing results are accurate and reliable each time. When the silk cake is being weighed, the measuring weights will automatically adjust to prevent the weighing results from being affected. 2. This device can weigh multiple yarn cakes simultaneously by setting up weighing components, and can achieve continuous automatic weighing operations by setting the movement trajectory of the yarn cake transport vehicle. It eliminates the need for workers to load and unload materials and then weigh them, reducing the risk of weighing, preventing damage to the yarn cakes, and greatly improving production efficiency.

[0014] 3. This device, by setting up a bellows component, can clean the surface of the yarn cake as the moving support rises, preventing debris and waste yarn adsorbed by the upstream process from affecting the balancing result. When the moving support descends, the bellows component can increase the stability of its descent, preventing the yarn cake from falling off due to a sudden drop, further protecting the yarn cake, preventing risk accidents, and improving production safety.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figure 1-7 This invention provides a technical solution for a stabilizing device for weighing silk cakes: it includes a support base 1, a support housing 2 slidably mounted on the upper surface of the support base 1, a movable bracket 3 slidably mounted inside the support housing 2, multiple weighing components 4 for weighing the silk cakes mounted on the movable bracket 3, a bellows component 5 mounted on the upper end of the inside of the support housing 2, multiple sets of evenly distributed transmission gears 22 rotatably mounted inside the support housing 2, each set consisting of four gears, each set of transmission gears 22 being driven by a transmission chain 23, a connecting block 24 fixedly mounted on the transmission chain 23, the connecting block 24 being fixedly connected to the movable bracket 3, multiple drive motors 21 fixedly mounted on the outside of the transmission gears 22, the drive ends of the drive motors 21 being fixedly mounted in the middle of the corresponding transmission gears 22, and multiple drive cylinders 11 fixedly mounted on the support base 1 for moving the support housing 2.

[0019] This device consists of two symmetrically arranged structures. When the silk cake transport vehicle carries the silk cake into the space between the two devices, the drive cylinder 11 pushes the support housing 2 to move to both sides of the silk cake transport vehicle. At this time, the weighing component 4 supports the core cylinder in the middle of the silk cake. Then, the drive motor 21 starts and drives the connecting block 24 through the transmission gear 22 and the transmission chain 23, so that the moving bracket 3 and the weighing component 4 rise synchronously, thereby driving the silk cake to rise. At this time, the silk cake is removed from the load position of the transport vehicle. Then, the drive cylinder 11 controls the support housing 2 to move away from the silk cake transport vehicle. After it is completely away from the silk cake transport vehicle, the drive motor 21 continues to work and drives the moving bracket 3 and the weighing component 4 to continue to rise to the maximum position. At this time, multiple weighing components 4 can weigh each silk cake. When the moving bracket 3 and the weighing component 4 are stable, the system will automatically collect the weight data of each silk cake and feed it back to the control system in real time through the signal transmission module to complete accurate measurement. After the measurement is completed, the drive motor 21 reverses and drives the connecting block 24 to descend through the transmission gear 22 and the transmission chain 23, so that the moving bracket 3 and the weighing component 4 fall back synchronously. Then the drive cylinder 11 controls the support housing 2 to move closer to the silk cake transport vehicle until the silk cake moves back to the bearing position of the transport vehicle. Then the drive motor 21 drives the moving bracket 3 and the weighing component 4 to continue to descend to the initial position. At this time, the weighing component 4 is completely separated from the silk cake core cylinder, the drive cylinder 11 drives the support housing 2 to reset, and the device returns to the standby state. Furthermore, this device can simultaneously measure multiple silk cakes individually and achieve highly automated weighing, eliminating the need for workers to remove the silk cakes and measure them one by one. This significantly improves weighing efficiency and safety, effectively reducing errors and labor intensity caused by manual operation. The entire weighing process is completed without the transport vehicle moving, avoiding the risk of collision or deformation that may occur during the handling of the silk cakes. In addition, the device sets the movement trajectory of the silk cake transport vehicle, allowing multiple silk cake transport vehicles to enter the weighing area in sequence to complete automated weighing, realizing assembly line operation.

[0020] The weighing component 4 includes a support base plate 41, a support platform 31 on the movable bracket 3, a weighing device 42 on the lower surface of the support base plate 41, the weighing device 42 being fixedly mounted on the support platform 31, a rotating bracket 44 on one side of the support base plate 41, a rotating base 45 rotatably mounted on the rotating bracket 44, the rotating base 45 being fixedly mounted on the inner side wall of the support housing 2, and an upper support arm 441 fixedly mounted on the upper end of the rotating bracket 44 near the support base plate 41. A measuring weight 442 is slidably installed on one end of the plate 41. A lower support arm 443 is fixedly installed on the lower end of the rotating bracket 44 near the support base plate 41. The lower support arm 443 is located above the support platform 31. A limit bracket 451 is fixedly installed on the side of the rotating base 45 near the rotating bracket 44. An L-shaped lifting rod 43 for lifting the silk cake is fixedly installed on the upper surface of the support base plate 41 away from the rotating base 45. A limit baffle 431 for limiting the position of the silk cake is fixedly installed on the L-shaped lifting rod 43. When the support housing 2 moves toward both sides of the silk cake transport vehicle, the end of the L-shaped lifting rod 43 is inserted into the silk cake core cylinder to provide effective support for the silk cake. When the moving bracket 3 drives the weighing component 4 to rise, the L-shaped lifting rod 43 drives the silk cake to rise. At this time, the support platform 31 rises and pushes the lower support arm 443. Then, the lower support arm 443 rotates around the rotating base 45 under the action of the thrust. The upper support arm 441 is also driven to rotate around the rotating base 45. The upper support arm 441 drives the measuring weight 442 away from the support base plate 41. A spring is fixedly installed inside the moving bracket 3 at the position corresponding to the upper support arm 441 to prevent the upper support arm 441 from being unable to move in a vertical state. When the support platform 31 rises and drives the upper support arm 441 to rotate, it will compress the spring and store elastic potential energy. When the moving bracket 3 rises to the maximum position, the weight of the silk cake is transmitted to the weighing device 42. The weighing device 42 weighs it and then feeds it back to the external control system. After the weighing data is processed, a report is automatically generated and uploaded to the data center. After the measurement is completed, the movable bracket 3 descends to its initial position. At this time, the upper support arm 441 passes the equilibrium position under the action of the spring. Subsequently, under the action of gravity, both the upper support arm 441 and the lower support arm 443 return to their original positions. At this time, the lower support arm 443 is supported by the support plate 41. The weighing device 42 weighs the measuring weight 442. Because the measuring weight 442 is slidably connected to the upper support arm 441, the weight of the upper support arm 441 is not transferred to the weighing device 42. The limiting bracket 451 is used to limit the position of the lower support arm 443 and the rotating bracket 44 to prevent the weight of the upper support arm 441 from being transferred. The weight is directed to the weighing device 42. Since the weight of the lower support arm 443 is a fixed value, after the yarn cake is weighed, the lower support arm 443 falls on the support base plate 41 and is weighed by the weighing device 42. When measuring the weight of the yarn cake, the measuring weight 442 is lifted to prevent its weight from being added to the yarn cake weighing data. This allows the device to perform self-testing when the yarn cake is not being weighed. If the reading deviates from the preset weight value of the lower support arm 443, it indicates that the weighing device 42 has a malfunction or zero drift, which facilitates subsequent maintenance and calibration and ensures the long-term stability of weighing accuracy.

[0021] Multiple evenly distributed sliding brackets 411 are fixedly installed on both sides of the support base plate 41. A sliding support rod 412 is slidably clamped in the middle of the sliding bracket 411, and the sliding support rod 412 is fixedly installed on the movable bracket 3.

[0022] When the support platform 31 rises and falls, the support base plate 41 is driven by the sliding support rod 412 to always remain in a horizontal state, maintaining stability during rise and fall, and avoiding the impact on weighing accuracy caused by tilting and resulting shift in the center of gravity of the yarn cake.

[0023] The bellows component 5 includes an upper connecting support 51, and a lower connecting support 52 is provided below the upper connecting support 51. The upper connecting support 51 is fixedly installed on the inner upper surface of the support housing 2, and the lower connecting support 52 is fixedly installed on the top of the movable bracket 3. A corrugated pipe 53 is fixedly connected between the upper connecting support 51 and the lower connecting support 52. Two ventilation pipes 6 are fixedly installed inside the movable bracket 3. Multiple sets of evenly distributed air blowing pipes 61 are fixedly installed on the ventilation pipes 6, with two in each set. The opening end of the air blowing pipes 61 faces the weighing component 4. Two valve components 54 corresponding to the ventilation pipe 6 are fixedly installed on the connecting support 52. The connecting pipe 541 is fixedly installed on the lower connecting support 52. A first connecting port 542 is opened in the middle of the connecting pipe 541. A first sealing plate 543 is slidably installed below the valve component 54. Multiple sealing springs 544 are fixedly connected between the first sealing plate 543 and the connecting pipe 541. A second sealing plate 546 is slidably installed in the middle of the upper surface of the first sealing plate 543. A second connecting port 545 is opened in the middle of the first sealing plate 543.

[0024] When the movable support 3 rises, it drives the lower connecting support 52 to rise, which compresses the bellows 53. At this time, the air inside the bellows 53 is squeezed through the valve component 54 and enters the ventilation pipe 6. The diameter of the blowing pipe 61 is much smaller than the diameter of the internal channel of the ventilation pipe 6, so the airflow will have a high velocity when passing through the blowing pipe 61. The opening of the blowing pipe 61 is directly opposite the wire cake on the L-shaped lifting rod 43. Therefore, when rising, the blowing pipe 61 can blow out airflow to blow off the dust or debris adsorbed on the wire cake, effectively avoiding impurities from affecting the weighing accuracy. When the movable support 3 descends, the bellows 53 returns to its extended state, and the external air flows back into the ventilation pipe 6 through the valve component 54, forming a circulating air path. It can also absorb the wire dust that has just been blown up and scattered in the air, preventing dust from accumulating inside the equipment and affecting the operation of the mechanical structure. When the connecting support 52 rises and compresses the bellows 53, the gas pushes the first sealing plate 543 downward. At this time, the sealing spring 544 is compressed, causing the first connecting port 542 to open. The gas smoothly passes through the first connecting port 542 and enters the interior of the ventilation pipe 6. When the connecting support 52 descends, the bellows 53 returns to its elongated state, and a negative pressure is formed inside the bellows 53. At this time, the first sealing plate 543, under the action of the sealing spring 544, presses tightly against the lower surface of the connecting pipe 541, thus closing the first connecting port 542. Meanwhile, the second sealing plate 546 is pushed by the air under the action of the negative pressure. During the sliding motion, the second connecting port 545 opens, allowing air to flow back through the ventilation pipe 6 into the corrugated pipe 53 via the second connecting port 545. Because the inner diameter of the first connecting port 542 is much larger than that of the second connecting port 545, the moving support 3 will quickly blow air to the outside through the ventilation pipe 6 and the air blowing pipe 61 when it rises, while slowly returning air through the smaller second connecting port 545 when it descends. This prevents the moving support 3 from descending too quickly, effectively buffering the descent stroke, improving the stability of the structure, and preventing the risk of the wire cake detaching due to excessive descent.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
