Description

Technical Field

[0001] This application relates to the field of solid alkali packaging technology, and in particular to an automatic clamping, shaping and conveying device for a solid alkali packaging machine. Background Technology

[0002] Currently, the chemical branch company generally uses semi-automatic packaging machines for upright bag packaging during the packaging and transportation of solid alkali products. After packaging, the bags are transported to the sewing station for sealing via conveyor belt. During this process, the sealing operators face significant challenges: first, they need to manually arrange and tie the inner bag, then press the inner bag into the outer bag, arrange the outer bag again, and finally feed it into the sewing machine. Throughout this entire operation, personnel are exposed to a working environment containing highly corrosive solid alkali dust for extended periods at close range. This work method not only exposes employees to significant occupational health risks such as dust inhalation and skin contact corrosion, but also poses safety hazards such as mechanical injuries.

[0003] To improve automation, a trolley-type conveyor structure has been attempted in existing technologies. This structure uses upper and lower cylinders to fix the bags and clamp the bag openings, and a long-rod cylinder drives the trolley to move along the chain conveyor for conveying. However, this solution has significant drawbacks: the entire equipment must be installed directly below the discharge port, exposed to a high-concentration, highly corrosive alkaline dust environment. The key actuators, cylinders, and their related pneumatic systems are highly susceptible to failure under harsh dust and corrosive conditions, such as piston rod jamming, seal corrosion failure, and pneumatic blockage. This leads to unstable overall equipment operation, a high failure rate, frequent maintenance, and difficulty in meeting the requirements for long-term stable operation, significantly reducing the level of automation.

[0004] Therefore, how to automate the entire process of solid alkali packaging bags from feeding to sealing and conveying, completely avoid personnel exposure to hazardous dust environments, and design a conveying and shaping mechanism that can operate reliably and stably for a long time under harsh working conditions are key technical problems that urgently need to be solved.

[0021] This utility model provides an automatic clamping, shaping, and conveying device for a solid alkali packaging machine, such as... Figure 1 As shown, it includes a lifting platform 1, a lifting component 2, a guide rail 3, a moving component 4, a rotating component 5, and a sealing component 6; one end of the lifting platform 1 is connected to the ground, and the other end of the lifting platform 1 is connected to the guide rail 3 through the lifting component 2; one end of the moving component 4 is rotatably connected to the guide rail 3, and the other end of the moving component 4 is connected to the fixed end of the rotating component 5; the movable end of the rotating component 5 is connected to the sealing component 6, and the movable end of the rotating component 5 can drive the sealing component 6 to perform air release and clamping operations on the packaging bag.

[0022] For example, the lifting platform 1 can be height-adjustable to accommodate different packaging bags or discharge port positions, ensuring that the bags fall accurately into the clamping station.

[0023] For example, one end of the lifting platform 1 is fixed to the ground or equipment frame, and the other end is connected to the guide rail 3 via the lifting assembly 2, allowing the height of the guide rail 3 to be adjustable to adapt to different working conditions. The moving assembly 4 is rotatably connected to the guide rail 3 via guide wheels 46 and can reciprocate along the length of the guide rail 3. The moving assembly 4 is connected to the fixed end of the rotating assembly 5. The movable output end of the rotating assembly 5 is connected to the sealing assembly 6. Through the movement of the rotating assembly 5, the sealing assembly 6 can accurately perform clamping, shaping, and necessary venting operations on the opening of the packaging bag.

[0024] In the embodiments of this application, such as Figure 1 As shown, the moving component 4 includes a first driving member 41, a first sprocket 42, a second sprocket 43, a guide wheel fixing plate 44, a transmission chain 45, and multiple guide wheels 46; the multiple guide wheels 46 are fixedly connected to the guide wheel fixing plate 44; the multiple guide wheels 46 are respectively disposed on both sides of the guide rail 3 and are tactilely connected to the guide rail 3; the fixed end of the rotating component 5 is connected to the guide wheel fixing plate 44; the first sprocket 42 and the second sprocket 43 are rotatably connected to both ends of the guide rail 3; the fixed end of the first driving member 41 is connected to the guide rail 3, and the output end of the first driving member 41 is connected to the first sprocket 42, which can drive the first sprocket 42 to rotate; one end of the transmission chain 45 is connected to one side of the guide wheel fixing plate 44, and the other end of the transmission chain 45 passes around the first sprocket 42 and the second sprocket 43 in sequence and is connected to the other side of the guide wheel fixing plate 44; the transmission chain 45 is engaged with the first sprocket 42 and the second sprocket 43; the guide wheel fixing plate 44 moves on the guide rail 3 through the transmission chain 45.

[0025] For example, the first drive member 41 can drive the rotating assembly 5 and the sealing assembly 6 to move into place along the guide rail 3. The synchronizing pull rod 65 helps to keep the bag opening flat.

[0026] For example, the first driving member 41 can drive the first sprocket 42 to rotate, and the first sprocket 42 drives the transmission chain 45 to move, thereby realizing the movement of the guide wheel fixing plate 44.

[0027] For example, this application uses a lifting platform 1 as a base to achieve overall height adjustment. The guide rail 3 is slidably connected to the lifting platform 1, and the guide wheel fixing plate 44 slides freely on the guide rail 3 through the guide wheel 46 with embedded bearings. The first driving component 41 includes a geared motor, which drives the transmission chain 45, thereby realizing the back-and-forth reciprocating movement of the guide wheel fixing plate 44 along the guide rail 3.

[0028] For example, guide wheel 46 uses a sealed bearing, and the chain may be equipped with a protective cover or use a corrosion-resistant chain.

The end of the rear clamping shaft 54 ​​away from the second driving member 51 passes through the connecting plate and is connected to the other end of the sealing assembly 6.

[0031] For example, the first gear 55 and the second gear 56 employ a closed gearbox or special surface treatment to enhance corrosion resistance.

[0032] For example, the rotating component 5 precisely controls the swing angle of the front swing rod 61 and the rear swing rod 62, thereby enabling the first clamping shaping plate 63 and the second clamping shaping plate 64 to clamp and vent the bag opening.

[0033] For example, the second driving component 51 includes a cylinder fixedly connected to the guide wheel fixing plate 44. The cylinder's extension and retraction can drive the swing arm 52, which in turn drives the front clamping shaft 53 to rotate. The first gear 55 meshes with the second gear 56, thereby causing the rear clamping shaft 54 ​​to rotate in the opposite direction. The rotational motion of the front and rear clamping shafts 53 and 54 is transmitted to the front swing arm 61 and the rear swing arm 62. The ends of the front and rear swing arms 61 and 62 are respectively connected to the first clamping shaping plate 63 and the second clamping shaping plate 64, thus realizing the clamping, shaping, and venting functions of the clamping shaping plates on the bag.

[0035] In the embodiments of this application, such as Figure 1As shown, the sealing assembly 6 includes a front swing rod 61, a rear swing rod 62, a first clamping shaping plate 63, and a second clamping shaping plate 64. One end of the front swing rod 61 is connected to the end of the front clamping shaft 53 away from the second driving member 51, and the other end of the front swing rod 61 is connected to the first clamping shaping plate 63. One end of the rear swing rod 62 is connected to the end of the rear clamping shaft 54 ​​away from the second driving member 51, and the other end of the rear swing rod 62 is connected to the second clamping shaping plate 64. The first clamping shaping plate 63 and the second clamping shaping plate 64 can perform air release and clamping operations on the packaging bag.

[0039] For example, the guide rail 3 slides up and down on the lifting platform 1. The third sprocket 21 is fixed on the lifting platform 1. The height of the guide rail 3 is adjusted by operating the third sprocket 21. The first limiter and the second limiter are installed at appropriate positions at the front and rear of the guide rail 3. The guide wheel 46 is mounted on the guide wheel fixing plate 44 by a pin. The limit rod is fixed on the guide wheel fixing plate 44. The transmission chain 45 is fixed to the front and rear positions of the guide wheel fixing plate 44 by chain pins on both sides. The first sprocket 42 is connected to the output shaft of the first drive component 41. The reduction motor can realize forward and reverse rotation. The second drive component 51 is fixedly connected to the guide wheel fixing plate 44. The piston rod of the second drive component 51 is fixedly connected to the swing arm 52 by a pin. The first gear 55 is installed in the front clamp. On shaft 53, the second gear 56 is mounted on the rear clamping shaft 54.

The clamping and shaping plate is fixed to the front and rear swing rods 62 by screws. The synchronous pull rod 65 is fixed to the front swing rod 61 and the rear swing rod 62. Compared with the traditional semi-automatic packaging machine, the clamping, shaping and conveying device for solid alkali packaging bags of this application effectively reduces the number of cylinders used. The equipment is far away from the alkali dust environment of the solid alkali packaging machine, thereby reducing equipment failure caused by alkali dust corrosion. It avoids manual sewing and prevents personnel from being exposed to solid alkali dust. This application improves the stable operation cycle of the equipment, enhances the level of automation control, and reduces labor service costs.
