DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 5 As shown, the utility model provides a bag packaging machine that is easy to position, including a fixing frame 1, a mixing bin 2 is provided inside the fixing frame 1, a limiting plate 3 is provided at the bottom of the mixing bin 2, and positioning mechanisms 4 are provided on both sides of the limiting plate 3;

[0024] The positioning mechanism 4 includes an arc-shaped plate 41, a clamping block 42, an extrusion block 43 and a threaded rod 44. The clamping block 42 is fixedly connected to the top surface of the arc-shaped plate 41, and the extrusion block 43 is connected to the clamping block 42 through the threaded rod 44. A connecting rod 45 is fixedly connected to one side of the arc-shaped plate 41.

[0025] Adopting the above solution: the fixed frame 1 provides a stable support structure for the entire device, ensuring that the internal components maintain a stable relative position during operation and will not be displaced or shaken due to external interference. The mixing bin 2 is the core area for material mixing. Its shape and size are designed to accommodate an appropriate amount of material to be mixed and provide a suitable spatial environment for the full mixing of the materials.

[0026] like Figures 2 to 4As shown, the top surface of the fixing frame 1 is fixedly connected to the fixing frame 101, the inner wall of the fixing frame 101 is connected to the outer wall of the top of the mixing bin 2, and a dust cover is installed on the top of the mixing bin 2. Slide grooves are provided on both sides of the limit plate 3, and the slide grooves are used for the sliding of the connecting rod 45. The bottom surface of the limit plate 3 is distributed with four supporting legs in a rectangular array, the top surfaces of the four supporting legs are connected to the bottom surface of the limit plate 3, and the bottom surfaces of the four supporting legs are installed with bases. There are two arc plates 41, and the two arc plates 41 can be spliced ​​into a circle. Threaded holes that are compatible with the threaded rod 44 are provided at both ends of the clamping block 42, and the threaded holes are designed for the movement of the threaded rod 44.

[0027] The above solution is adopted: the limit plate 3 is located at the bottom of the mixing bin 2, and plays the role of supporting and positioning the mixing bin 2. The slide grooves on both sides provide guidance and constraints for the sliding of the connecting rod 45, so that the connecting rod 45 can only move along a specific direction, thereby ensuring that the arc plate 41 connected thereto can accurately open and close. The four supporting legs on the bottom further enhance the stability of the limit plate 3, and the base at the bottom of the supporting legs can increase the contact area with the placement plane, disperse the pressure, and prevent the device from tipping over due to unstable center of gravity or uneven ground during operation. The curved plate 41 is a key component of the positioning mechanism 4. The two curved plates 41 can be spliced ​​into a circle. The clamping block 42 is fixed on the top surface of the curved plate 41. The threaded holes at both ends cooperate with the threaded rod 44. The position of the extrusion block 43 inside the clamping block 42 can be adjusted by rotating the threaded rod 44. Under the push of the threaded rod 44, the extrusion block 43 can apply a clamping force to the material packaging bag located in the clamping block 42, thereby stably fixing the material packaging bag in the curved plate 41 to prevent the container from shaking or displacing during the mixing process, which affects the mixing effect.

[0028] like Figures 3 to 5 As shown, the extrusion block 43 is located inside the clamping block 42, one end of the threaded rod 44 is rotatably connected to the extrusion block 43 through a bearing, and the other end of the threaded rod 44 is fixedly connected to a knob, and a power mechanism 5 is provided on one side of the connecting rod 45, the power mechanism 5 includes a first gear plate 51, a gear 52 and a second gear plate 53, the first gear plate 51 and the second gear plate 53 are respectively meshed and connected to the two sides of the gear 52, the top surfaces of the first gear plate 51 and the second gear plate 53 are fixedly connected to the fixing rod, the bottom surface of one end of the fixing rod is connected to the top surface of the connecting rod 45, and a driving motor is fixedly installed on the bottom surface of one side of the limit plate 3, and the output end of the driving motor is spline-connected to the gear 52.

[0029] The above scheme is adopted: the power mechanism 5 composed of the first tooth plate 51, the gear 52 and the second tooth plate 53 is the key transmission component to realize the opening and closing action of the arc plate 41. The driving motor drives the gear 52 to rotate. Since the first tooth plate 51 and the second tooth plate 53 are respectively engaged with the two sides of the gear 52, when the gear 52 rotates, the first tooth plate 51 and the second tooth plate 53 will move in opposite directions. The fixed rods on the top surfaces of the first tooth plate 51 and the second tooth plate 53 are connected to the connecting rod 45, thereby converting the linear motion of the tooth plate into the motion of the connecting rod 45, and then It drives the arc plate 41 to realize the opening and closing operation, and can automatically control the clamping and loosening of the material container, which is convenient for loading and unloading of materials. The bottom surfaces of the first tooth plate 51 and the second tooth plate 53 are fixedly connected to the limit slider, and the limit slider is slidably connected to the top surface of the limit plate 3. The limit slider is used to limit the first tooth plate 51 and the second tooth plate 53. The top surfaces of the first tooth plate 51 and the second tooth plate 53 are slidably connected with a supporting straight plate, which is connected to the fixed frame 1. The supporting straight plate is used to ensure the stable movement of the first tooth plate 51 and the second tooth plate 53.

[0030] The working principle and use process of the present invention are as follows: in the initial state, the driving motor is in a stopped state, and the two arc-shaped plates 41 are in a closed state under the action of the power mechanism 5, that is, the two arc-shaped plates 41 are spliced ​​into a circle. At this time, the threaded rod 44 is rotated to move the extrusion block 43 toward the direction close to the placement position of the material container, and the space size in the arc-shaped plate 41 is adjusted to accommodate the material container to be fixed. The packaging bag is placed at the discharge port at the bottom of the mixing bin 2, and then the packaging bag is connected to the clamping block 42 above the arc-shaped plate 41. The threaded rod 44 is rotated in the opposite direction to make the extrusion block 43 apply a clamping force to the packaging bag, so that the packaging bag is stably fixed in the arc-shaped plate 41.

[0031] Start the drive motor, which drives the gear 52 to rotate. The rotation of the gear 52 causes the first tooth plate 51 and the second tooth plate 53 engaged therewith to move in opposite directions. The first tooth plate 51 and the second tooth plate 53 drive the connecting rod 45 to slide in the slide groove of the limit plate 3 through the fixed rod. The connecting rod 45 then drives the arc plate 41 to open to both sides, thereby expanding the packaging bag and allowing the material to enter the interior of the packaging bag from the mixing bin 2.
