[0002] Salt quantitative packaging equipment is an automated packaging machine designed specifically for industrial salt and similar granular materials. It integrates automatic metering, filling, sealing and packaging functions. Its working principle is to feed material through a storage silo, and then control the weight precisely through three-stage feeding. When the material reaches the set value, it switches to fine feeding. Finally, the accuracy is ensured by a weighing sensor. Then, the bag clamping device clamps the packaging bag, automatically releases the material and seals it, completing the entire process.

[0003] Currently, in quantitative salt packaging equipment, an opening device is usually required to open the packaging bag for salt filling. Existing quantitative salt feeding packaging bag opening devices require multiple cylinders for transmission to open the packaging bag, which not only has high manufacturing costs but also leads to high operating and subsequent maintenance costs. Therefore, a quantitative salt feeding packaging bag opening device is proposed to address the above problems. Utility Model Content

This application discloses an opening device for a packaging bag used for quantitative salt feeding. (See also...) Figure 1 , Figure 2 , Figure 4 and Figure 5A packaging bag opening device for quantitative salt feeding includes a base frame 1, a bracket 2 fixedly installed on one side of the base frame 1, a movable frame 3 slidably connected to the surface of the bracket 2, two sliding rods 4 passing through the interior of the movable frame 3, the surface of the sliding rods 4 slidably connected to the inner cavity of the movable frame 3, a reciprocating mechanism 5 is provided inside the movable frame 3, the reciprocating mechanism 5 is used in conjunction with the sliding rods 4, a mounting frame 41 is fixedly installed at one end of each of the two sliding rods 4, and a suction cup 42 is fixedly installed on the opposite side of each of the two mounting frames 41; The reciprocating mechanism 5 includes a base plate 51, which is fixedly installed inside the movable frame 3. A rotating shaft 5208 is rotatably connected to the surface of the base plate 51. A rocker block 52 is fixedly connected to the top of the rotating shaft 5208. A guide groove 5201 is formed on the surface of the rocker block 52. Guide rods 5202 are fixedly installed on the top of the two slide rods 4. The guide rods 5202 cooperate with the guide grooves 5201. A horizontal plate 53 is fixedly installed on one side of the base frame 1. One end of the horizontal plate 53 passes through the movable frame 3 and is slidably connected to the inner cavity of the movable frame 3. A horizontal bar 5203 is fixedly installed at the bottom of the rocker block 52. A through groove 5204 is formed on the surface of the horizontal plate 53. A vertical bar 5205 is fixedly installed at the bottom of the horizontal bar 5203. The vertical bar 5205 is slidably connected inside the through groove 5204. A power assembly 54 is fixedly installed on the surface of the horizontal plate 53. The power assembly 54 cooperates with the movable frame 3. The power assembly 54 drives the movable frame 3 to slide back and forth on the surface of the bracket 2, so that the movable frame 3 drives the rocker block 52 to move laterally via the base plate 51. The vertical rod 5205 is slidably connected inside the through groove 5204, so that the horizontal plate 53 restricts the position of the rocker block 52 via the horizontal rod 5203, so that the rocker block 52 swings laterally back and forth. The rocker block 52 drives the slide rod 4 to move back and forth via the guide groove 5201 and the guide rod 5202, so that the two slide rods 4 drive the two mounting frames 41 to move simultaneously, so that the two mounting frames 41 move closer or further away from each other. When the salt packaging bag moves between the two mounting frames 41, the two mounting frames 41 move closer to each other, so that the suction cup 42 is attached to the surface of the packaging bag. Then the two mounting frames 41 move further away from each other, so that the suction cup 42 drives the two sides of the packaging bag to separate, thus opening the packaging bag.

[0018] Reference Figure 3A slider 31 is fixedly installed at the bottom of the movable frame 3. A groove 32 is opened on the surface of the bracket 2. The slider 31 is slidably connected to the inside of the groove 32. A first limiting block 33 is fixedly installed on the surface of the slider 31. A first limiting groove 34 is opened inside the groove 32. The surface of the first limiting block 33 is slidably connected to the inner cavity of the first limiting groove 34. The slider 31 is slidably connected to the inside of the groove 32. The first limiting block 33 and the first limiting groove 34 stabilize the position of the slider 31 and prevent the slider 31 from separating from the groove 32. This allows the movable frame 3 to slide on the surface of the bracket 2 through the slider 31 and the groove 32, while stabilizing the position of the movable frame 3 and preventing positional deviation of the movable frame 3.

[0019] Reference Figure 5 A second limiting block 5206 is fixedly installed on the surface of the vertical rod 5205, and a second limiting groove 5207 is opened inside the through groove 5204. The second limiting block 5206 is slidably connected inside the second limiting groove 5207. The second limiting block 5206 and the second limiting groove 5207 can effectively stabilize the position of the vertical rod 5205 inside the through groove 5204, and prevent the vertical rod 5205 from separating from the through groove 5204, thus affecting the limiting work of the rocker block 52.

[0020] Reference Figure 5 A positioning block 5209 is fixedly installed at the bottom of the rotating shaft 5208. The positioning block 5209 is rotatably connected to the inside of the substrate 51. By rotatably connecting the positioning block 5209 to the inside of the substrate 51, the position of the rotating shaft 5208 can be effectively stabilized, and the position of the rocker block 52 can be avoided by preventing the rotating shaft 5208 from separating from the substrate 51.

[0021] Reference Figure 2 The power assembly 54 includes a motor 5401, which is fixedly mounted on the surface of the horizontal plate 53. A first connecting rod 5402 is fixedly sleeved on the output end of the motor 5401. A second connecting rod 5403 is rotatably connected to one end of the first connecting rod 5402. One end of the second connecting rod 5403 is rotatably connected to one side of the movable frame 3. A support rod 5404 is rotatably sleeved on one end of the first connecting rod 5402. One end of the support rod 5404 is rotatably sleeved inside the second connecting rod 5403. A bracket 5405 is fixedly mounted on one side of the movable frame 3. One end of the second connecting rod 5403 is rotatably connected inside the bracket 5405. The motor 5401 drives the first connecting rod 5402 to rotate. The first connecting rod 5402 drives the second connecting rod 5403 to move through the support rod 5404. The bracket 5405 rotatably connects one end of the second connecting rod 5403 to the movable frame 3, so that the second connecting rod 5403 drives the movable frame 3 to slide back and forth on the bracket 2.

[0022] Working principle: The motor 5401 drives the first connecting rod 5402 to rotate. The first connecting rod 5402 drives the second connecting rod 5403 to move via the support rod 5404. The bracket 5405 connects one end of the second connecting rod 5403 to the moving frame 3, so that the second connecting rod 5403 drives the moving frame 3 to move back and forth. The position of the slider 31 is stabilized by the first limiting block 33 and the first limiting groove 34, so that the moving frame 3 slides back and forth on the bracket 2 via the slider 31 and the sliding groove 32. This causes the moving frame 3 to drive the rocker block 52 to move laterally via the base plate 51. The position of the vertical rod 5205 inside the through groove 5204 is stabilized by the second limiting block 5206 and the second limiting groove 5207, and the vertical rod 5205 is slidably connected to the through groove 5204. Inside, the horizontal plate 53 restricts the position of the swing block 52 through the horizontal bar 5203, and stabilizes the position of the rotating shaft 5208 through the positioning block 5209, so that the swing block 52 can rotate through the rotating shaft 5208, thereby causing the swing block 52 to swing laterally back and forth. This causes the swing block 52 to drive the slide bar 4 to move back and forth through the guide groove 5201 and the guide rod 5202, thereby causing the two slide bars 4 to drive the two mounting brackets 41 to move simultaneously, so that the two mounting brackets 41 move closer or further away from each other. When the salt packaging bag moves between the two mounting brackets 41, the two mounting brackets 41 move closer to each other, so that the suction cup 42 is attached to the surface of the packaging bag. Then the two mounting brackets 41 move further away from each other, so that the suction cup 42 causes the two sides of the packaging bag to separate, thereby opening the packaging bag.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
