Description

Technical Field

[0001] This invention belongs to the field of silica production equipment, and specifically relates to an automatic silica wrapping device. Background Technology

[0002] Silica is a high-performance fine chemical powder material widely used in various industrial fields such as rubber, coatings, plastics, and daily chemicals. Finished silica products are mostly stored and transported in boxes. Because powder materials are highly susceptible to moisture absorption and dust contamination, and because boxes are prone to loosening, falling apart, or damage during stacking and transportation, it is essential to apply a protective wrapping film to the finished silica products after packaging to ensure the integrity and quality stability of the product during warehousing and logistics.

[0003] Currently, the mainstream stretch wrapping equipment for precipitated carbon black boxes in the industry adopts a gantry frame that rotates around the entire cargo, which has the following problems: 1. During operation, the gantry and its supporting wrapping mechanism have a large overall displacement range, poor overall equipment rigidity and insufficient stability. Under high-speed continuous wrapping operation, problems such as mechanism vibration, film offset and wrapping misalignment are very likely to occur, which seriously affect the flatness and sealing of the packaging.

[0004] 2. The technical shortcoming of constant film tension and inability to adaptively adjust it means that the film tension cannot be matched to the corresponding tightness for silica boxes of different weights and sizes. This can easily lead to problems such as too little tension and too loose film wrapping, resulting in poor film adhesion; or too much tension and too tight film wrapping, which rigidly compresses the box, causing the silica box to deform, tilt, or even collapse, damaging the finished product.

[0005] It is difficult to meet the needs of modern factories for large-scale, high-precision, low-loss, and high-stability automated packaging production. Summary of the Invention

[0006] (a) Technical problems to be solved To overcome the shortcomings of existing technologies, an automatic wrapping device for silica is proposed to address one or more existing problems.

[0007] (II) Technical Solution This invention is achieved through the following technical solution: This invention proposes an automatic wrapping and packaging device for silica, the structure of which includes a placement platform, a track base, a gantry frame, a film roller, a film roller assembly base, a lifting frame, and a controller; Both sides of the placement platform are equipped with rail seats. The gantry frame is mounted on the rail seats. A liftable lifting frame is installed inside the gantry frame. One side of the lifting frame is fixedly connected to the film roller mounting seat. A film roller is rotatably mounted on the film roller mounting seat. The film roller is used for assembling the whole roll of film. A tension adjustment device is also fixed on the lifting frame. The tension adjustment device is used to adjust the tension required for film winding and unwinding. A rotatable turntable is installed on the top of the placement platform. A first power source for driving the turntable to rotate is also installed on the placement platform. The movement of the gantry frame, the lifting of the lifting frame, and the first power source are all controlled by a control box.

[0008] Furthermore, a transmission ring is fixed to the bottom of the turntable, and a transmission mechanism is assembled inside the placement platform. The first power source drives the transmission ring to rotate through the transmission mechanism. The bottom of the transmission ring has a groove, and one or more support rings are fixed in the groove. The support rings are assembled on the top of the rotating seat, which also has a groove. A first sliding roller is assembled on the side wall of the groove on the top of the rotating seat, and a second sliding roller is assembled on the bottom of the groove on the top of the rotating seat. The rotating seat is connected to the support rings through the first and / or second sliding rollers. The turntable, transmission ring, and rotating seat are all located inside the placement platform. The rolling friction structure of the support rings in conjunction with the first and second sliding rollers replaces the traditional hard sliding friction structure, greatly reducing the rotational resistance of the turntable, effectively reducing equipment operating energy consumption and mechanical wear, reducing equipment jamming and abnormal noise malfunctions, significantly extending the service life of the transmission and rotation mechanisms, and reducing equipment maintenance costs. At the same time, the embedded structure design simplifies the equipment volume, reduces the overall height of the machine, and reduces the space occupied in the factory.

[0009] Furthermore, the bottom of the rotating seat is provided with a lifting groove, and a lifting top plate is movably installed in the lifting groove. The bottom of the lifting top plate passes through the bottom of the rotating seat and connects with the interior of the placement platform. A first electrically controlled telescopic component is installed between the top of the lifting top plate and the rotating seat. The placement platform is also provided with a second power source for driving the extension and retraction of the first electrically controlled telescopic component. The liftable lifting top plate and the first electrically controlled telescopic component can raise the turntable according to the size of the box, so that the bottom of the box is separated from the surface of the placement platform, completely avoiding damage and powder leakage caused by long-term friction between the bottom of the box and the equipment platform, and protecting the integrity of the finished silica packaging in all aspects.

[0010] Furthermore, the first power source is an electric motor, the transmission mechanism is a gear set, the transmission ring is a toothed ring with tooth grooves on the side, and the tooth groove height of the toothed ring is the same as the tooth groove height of the gear set, and the height difference is greater than or equal to the lifting height of the lifting top plate.

[0011] Furthermore, a second electrically controlled telescopic component is fixed to the top of the rotating seat. A detection ring is fixed to the side of the second electrically controlled telescopic component adjacent to the transmission ring. A pressure sensor is mounted on the side of the detection ring adjacent to the transmission ring. A second power source on the placement platform is used to drive the telescopic movement of the second electrically controlled telescopic component. The second electrically controlled telescopic component, the detection ring, and the pressure sensor form a weight detection mechanism. Before operation, the weight of the goods to be packaged can be accurately detected, and overweight goods can be automatically identified. This avoids forced operation under overweight conditions, which can cause wear and damage to the transmission mechanism and turntable structure. This reduces the probability of equipment failure from the source and ensures long-term stable operation of the equipment. When the weight is overweight, an alarm is triggered directly. The lifting and lowering detection method of the detection ring can prevent overweight goods from directly damaging the detection mechanism.

[0012] Furthermore, the control box is also connected to an audible and visual alarm.

[0013] Furthermore, the placement platform is provided with a clearance groove for the connection of the wires / pipes of the first electronically controlled telescopic component on the side adjacent to the second power source.

[0014] Furthermore, the second power source is a pneumatic station or a hydraulic station, and the first and second electrically controlled telescopic components are cylinders or hydraulic cylinders.

[0015] Furthermore, the tension adjustment device includes an adjustment mounting base, guide rollers, a chute, a sliding seat, an adjustment roller, and a third electrically controlled telescopic component. Guide rollers are rotatably mounted on the adjustment mounting base, and there are two or more guide rollers. A chute is provided on the adjustment mounting base, with the end of the chute penetrating the adjustment mounting base. The sliding seat is slidably mounted within the chute, and an adjustment roller is rotatably mounted on the sliding seat. The third electrically controlled telescopic component is used to drive the adjustment roller on the sliding seat to approach or move away from two of the guide rollers. The interval between the two guide rollers is less than the width of the adjustment roller. The third electrically controlled telescopic component drives the adjustment roller to squeeze the film, precisely adjusting the film output tension.

[0016] Furthermore, the third electrically controlled telescopic component is a pneumatic cylinder, a hydraulic cylinder, or an electric telescopic rod.

[0017] (III) Beneficial Effects One of the above technical solutions has the following advantages or beneficial effects: 1. This device abandons the traditional gantry crane rotating around the goods operation mode and adopts the operation structure of "goods rotation + fixed-point lifting and displacement of the wrapping mechanism". The gantry crane only makes small lateral alignment adjustments and does not rotate or swing in a large range. This avoids the problems of mechanism vibration, film offset and wrapping misalignment when traditional equipment operates at high speed. The equipment has strong rigidity and high stability.

[0018] 2. An independent tension adjustment device allows for precise adjustment of the film tension, enabling flexible adjustment of the wrapping tightness based on the weight, size, and material of the precipitated silica box. This avoids both film detachment and box breakage caused by excessively loose wrapping, and box deformation and collapse caused by excessively tight wrapping, thus comprehensively improving packaging quality and neatness.

[0019] 3. The gantry frame is horizontally adjustable and the lifting frame is vertically adjustable, which can be adapted to white carbon black boxes of different lengths, widths, heights and weights, making it highly versatile; the entire process is automatically controlled by the controller through programming, without the need for manual intervention, which greatly reduces the intensity of manual labor and improves the level of intelligent production.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to embodiments, but the implementation of the present invention is not limited thereto.

[0022] Example 1: like Figure 1 As shown, the present invention provides an automatic wrapping packaging device for silica: its structure includes a placement platform 1, a track seat 2, a gantry frame 5, a film roller 6, a film roller assembly seat 7, a lifting frame 9, and a controller 11; The placement platform 1 is equipped with track seats 2 on both sides. The gantry frame 5 is mounted on the track seats 2. The gantry frame 5 is equipped with a liftable lifting frame 9. One side of the lifting frame 9 is fixedly connected to the film roller mounting seat 7. The film roller 6 is rotatably mounted on the film roller mounting seat 7. The film roller 6 is used for assembling the whole roll of film. The lifting frame 9 is also fixed with a tension adjustment device 8. The tension adjustment device 8 is used to adjust the tension required for film winding and film output. The top of the placement platform 1 is equipped with a rotatable turntable 3. The placement platform 1 is also equipped with a first power source 4 for driving the turntable 3 to rotate. The movement of the gantry frame 5, the lifting of the lifting frame 9, and the first power source 4 are all controlled by the control box 11.

[0023] When in use, first, fix the entire roll of packaging film onto the film roller 6, pull the film end out to the working position, and after the equipment is powered on, complete the machine initialization self-test through the controller 11.

[0024] Next, the packed silica goods are placed stably on the upper surface of the turntable 3 of the placement platform 1. According to the size of the goods, the gantry 5 is controlled by the controller 11 to move laterally along the track seat 2 for alignment. At the same time, the vertical height of the lifting frame 9 is adjusted so that the film roller 6 and the tension adjustment device 8 match the starting height of the goods wrapping.

[0025] Then, the equipment is started by the controller 11. The first power source 4 drives the turntable 3 and the goods above to rotate at a constant speed. In conjunction with the lifting frame 9, it lifts and lowers at a constant speed from bottom to top to complete the all-round continuous wrapping operation on the outer surface of the goods.

[0026] Finally, after the wrapping of a single batch of goods is completed, all mechanisms of the equipment are reset and the machine is stopped. The packaged product is then manually removed, completing a single operation cycle.

[0027] This embodiment adopts the "cargo rotation + machine head lifting and film feeding" operation mode, replacing the traditional gantry frame integral rotating film wrapping structure. The equipment has stronger operation stability and no large swing and shaking problems. It avoids the problems of mechanism vibration, film offset and film misalignment when traditional equipment operates at high speed. The equipment has strong rigidity and high stability.

[0028] The independent tension adjustment device can precisely adjust the film delivery tension, and flexibly adjust the tightness of the wrapping according to the weight, size and material of the precipitated silica box. This avoids the film falling off and the box falling apart due to excessively loose wrapping, and also prevents the box from deforming and collapsing due to excessively tight wrapping, thus comprehensively improving the packaging quality and neatness.

[0029] The gantry frame is horizontally adjustable and the lifting frame is vertically adjustable, making it suitable for white carbon black boxes of different lengths, widths, heights, and weights, with strong versatility. The entire process is automated through a controller program, requiring no manual intervention, which greatly reduces the intensity of manual labor and improves the level of intelligent production.

[0030] like Figure 2-5 As shown, in one embodiment, a transmission ring 303 is fixed to the bottom of the turntable 3, and a transmission mechanism 401 is assembled inside the placement platform 1. The first power source 4 drives the transmission ring 303 to rotate through the transmission mechanism 401. The bottom of the transmission ring 303 is provided with a groove, and one or more support rings 301 are fixed in the groove at the bottom of the transmission ring 303. The support rings 301 are assembled on the top of the rotating seat 308. The top of the rotating seat 308 is also provided with a groove, and a first sliding roller 306 is assembled on the side wall of the groove at the top of the rotating seat 308. A second sliding roller 307 is fitted at the bottom of the groove at the top of the rotating seat 308. The rotating seat 308 is connected to the support ring 301 through the first sliding roller 306 and / or the second sliding roller 307. The turntable 3, the transmission ring 303, and the rotating seat 308 are all located within the placement platform 1. The rolling friction structure of the support ring in conjunction with the first and second sliding rollers replaces the traditional hard sliding friction structure, greatly reducing the rotational resistance of the turntable, effectively reducing equipment operating energy consumption and mechanical wear, reducing equipment jamming and abnormal noise malfunctions, significantly extending the service life of the transmission and rotation mechanisms, and reducing equipment operation and maintenance costs. At the same time, the embedded structure design simplifies the equipment volume, reduces the overall height of the machine, and reduces the space occupied in the factory.

[0031] Example 2: like Figure 2-5 As shown, compared with the previous embodiment, the rotating seat 308 in this embodiment is provided with a lifting groove 311 at the bottom. A lifting top plate 310 is movably assembled in the lifting groove 311. The bottom of the lifting top plate 310 passes through the bottom of the rotating seat 308 and connects with the interior of the placement platform 1. A first electrically controlled telescopic component 309 is assembled between the top of the lifting top plate 310 and the rotating seat 308. The placement platform 1 is also provided with a second power source 12 for driving the first electrically controlled telescopic component 309 to extend and retract.

[0032] like Figure 2-5 As shown, in one embodiment, the first power source 4 is a motor, the transmission mechanism 401 is a gear set, and the transmission ring 303 is a toothed ring with tooth grooves on the side. The tooth groove height of the toothed ring is the same as the tooth groove height of the gear set, and the height difference is greater than or equal to the lifting height of the lifting top plate 310.

[0033] In use, based on the bottom dimensions and outward extension of the silica box, the controller 11 starts the second power source 12, which drives the first electrically controlled telescopic component 309 to extend and push the rotating seat 308 upward along the lifting top plate 310, thereby lifting the turntable 3 and the goods as a whole. This ensures that the suspended part of the goods that exceeds the turntable is completely removed from the table surface 1, eliminating the risk of contact friction. During the lifting process, the height difference redundancy between the gear ring and the gear set ensures that the transmission structure is stably engaged throughout the entire process, and the rotation is smooth without jamming.

[0034] This embodiment introduces a newly added adaptive height-adjustable turntable 3 structure, which can flexibly raise the turntable 3 according to the bottom dimensions of different specifications of precipitated silica boxes. This completely solves the problem of hard friction between the bottom of the goods and the table surface in traditional equipment, effectively preventing wear and damage to the bottom of the box and ensuring the integrity of the finished product packaging in all aspects. At the same time, by limiting the height difference between the gear ring and the gear set, it ensures that the transmission structure is always effectively engaged during the adjustment of the turntable, preventing malfunctions such as tooth slippage, free rotation, and transmission failure. This significantly improves the equipment's adjustment compatibility and operational stability, and can also adapt to irregularly shaped box packaging with irregular bottoms and different extension dimensions.

[0035] Example 3: like Figure 2-5 As shown, compared to the previous embodiment, in this embodiment, the top of the rotating seat 308 is fixed with a second electrically controlled telescopic component 302. A detection ring 312 is fixed to the side of the second electrically controlled telescopic component 302 adjacent to the transmission ring 303. A pressure sensor 313 is assembled on the side of the detection ring 312 adjacent to the transmission ring 303. The second power source 12 provided on the placement platform 1 is used for the telescopic drive of the second electrically controlled telescopic component 302. The weight detection mechanism is composed of the second electrically controlled telescopic component, the detection ring and the pressure sensor. Before operation, the weight of the goods to be packaged can be accurately detected, and overweight goods can be automatically identified. This avoids forced operation under overweight conditions, which can wear and damage the transmission mechanism and turntable structure. This reduces the probability of equipment failure from the source and ensures long-term stable operation of the equipment. When the weight is overweight, an alarm is directly triggered. The lifting and lowering detection method of the detection ring can prevent the overweight goods from directly crushing the detection mechanism.

[0036] like Figure 1 As shown, in one embodiment, the control box 11 is also connected to an audible and visual alarm 10.

[0037] like Figure 2-5 As shown, in one embodiment, the placement platform 1 has a clearance groove 314 for connecting the wire / pipe of the first electronically controlled telescopic component 309 on the side adjacent to the second power source 12.

[0038] In one embodiment, the second power source 12 is a pneumatic station or a hydraulic station, and the first electrically controlled telescopic component 309 and the second electrically controlled telescopic component 302 are cylinders or hydraulic cylinders.

[0039] During use, before the wrapping operation, the controller 11 can control the second power source 12 to drive the second electronically controlled telescopic component 302 to extend, which will drive the detection ring 312 to move up and fit the transmission ring 303. The pressure sensor 313 will collect the overall weight data of the goods in real time and feed it back to the controller 11 for data comparison.

[0040] If the weight of the detected goods exceeds the rated load of the equipment, the controller 11 will immediately trigger the alarm devices such as the audible and visual alarm 10 to issue a warning, and the equipment will automatically lock and stop, prohibiting the start of the wrapping process; if the weight is qualified, the equipment will lower the detection ring 312 and enter the turntable lifting and wrapping operation process.

[0041] During equipment operation, the air pipes and oil pipes of the first electrically controlled telescopic component 309 are all housed inside the clearance groove 314 to prevent the pipelines from being squeezed, pulled and worn during the lifting and telescopic process.

[0042] This embodiment adds a pre-positioned weight detection mechanism and an audible and visual warning mechanism, which can accurately identify overweight goods before operation, avoiding wear and damage to transmission gears, turntables 3, and sliding rollers caused by forced operation under heavy load conditions, significantly reducing equipment failure rate and extending equipment life. The detection ring lifting and contact detection method, unlike the fixed pressure detection structure, effectively avoids deformation and damage to the detection element caused by direct pressure from the goods on the sensor, greatly improving the service life and detection accuracy of the detection mechanism. At the same time, a dedicated clearance groove is added to solve the problems of long-term exposure of telescopic pipelines, telescopic interference, and crushing damage, ensuring stable long-term continuous operation of the equipment; the pneumatic / hydraulic driven telescopic structure has a large load-bearing capacity and smooth operation, suitable for operation with various sizes of light and heavy precipitated silica boxes.

[0043] This structure adopts a split lifting and detection design. The sensor is only subjected to force during detection and completely unloaded during operation. This ensures the accuracy and reliability of weight detection data, and also achieves long-term stable operation with no wear and tear on the sensor. With the real-time audible and visual alarm function, it can quickly remind operators to sort overweight and unqualified workpieces, avoid ineffective work, improve the overall operation efficiency of the production line, and realize visual early warning of equipment failure. This facilitates daily operation and maintenance of the equipment and is compatible with the standardized operation management of automated production lines in factories.

[0044] Example 4: like Figure 1 and 6As shown, compared to the previous embodiment, the tension adjustment device 8 in this embodiment includes an adjustment mounting base 801, a guide roller 802, a groove 803, a sliding seat 804, an adjustment roller 805, and a third electrically controlled telescopic component 806. The guide roller 802 is rotatably mounted on the adjustment mounting base 801, and there are two or more guide rollers 802. The groove 803 is provided on the adjustment mounting base 801, and the end of the groove 803 passes through the adjustment mounting base 801. The sliding seat 804 is slidably mounted in the groove 803, and the adjustment roller 805 is rotatably mounted on the sliding seat 804. The third electrically controlled telescopic component 806 is used to drive the adjustment roller 805 on the sliding seat 804 to approach or move away from two of the guide rollers 802. The gap between the two guide rollers 802 is less than the width of the adjustment roller 805. The adjustment roller is driven by the third electrically controlled telescopic component to squeeze the film, thereby precisely adjusting the film output tension.

[0045] In one embodiment, the third electrically controlled telescopic member 806 is a cylinder, a hydraulic cylinder, or an electric telescopic rod.

[0046] In use, the film is threaded between multiple sets of guide rollers 802 and adjusting rollers 805. According to the weight of the precipitated silica box, the hardness of the box and the packaging process requirements, the controller 11 controls the extension and retraction of the third electronically controlled telescopic component 806, which drives the sliding seat 804 to slide along the slide groove 803, and drives the adjusting roller 805 to squeeze or loosen the film, so as to accurately adjust the film output tension and wrapping tightness.

[0047] After setting the tension, start the equipment. Turntable 3 drives the goods to rotate and lifting frame 9 moves the film at a constant speed. Relying on constant and suitable film tension, the film is wrapped evenly without any deviation in film tightness or looseness.

[0048] After the operation is completed, each electrically controlled telescopic component, walking mechanism, and lifting mechanism is reset in sequence, ready for the next operation.

[0049] The tension adjustment device 8 disclosed in this embodiment has a simple structure, precise adjustment, and fast response speed. Utilizing the adjusting roller 805 to squeeze the film, it can steplessly fine-tune the film tension, overcoming the shortcomings of traditional equipment that maintains constant film tension and cannot adaptively adjust it. For lightweight boxes, the tension can be reduced to prevent deformation, tilting, and collapse; for heavy-duty boxes, the tension can be increased to ensure a tight film fit without loosening or falling off, adapting to the wrapping needs of all sizes of silica boxes. The dimensional matching design of the guide roller 802 and the adjusting roller 805 ensures stable film guidance, preventing deviation and wrinkles, significantly improving the flatness of the wrapping and the sealing performance of the packaging, greatly enhancing the equipment's versatility and adaptability.
