When this kind of packaging and filling device is feeding and packaging, it is very easy to have the problem of filling failure. The main reasons are that the opening degree of the bag mouth of the packaging bag is insufficient, the posture of the hot pot base materials changes during feeding, and the lower end of the packaging bag is not fully opened during feeding, resulting in the problem that the hot pot base materials cannot be fully filled in the packaging bag. Summary of the Utility Model

[0003] The utility model provides a filling and bag expanding device to solve the deficiencies of the above-mentioned prior art, solve the problems of filling failure of hot pot base materials and incomplete filling, and has strong practicability.

[0004] In order to achieve the purpose of the utility model, the following technology is proposed:

[0005] A filling and bag expanding device includes a feeding shell. A cylinder is installed at the lower end of the feeding shell. The movable end of the cylinder is provided with a movable plate. The inner end of the movable plate is provided with a movable frame. The movable frame is sleeved on the feeding shell. One side of the movable frame is provided with a concave member. The inner end of the concave member is provided with a movable convex plate. The inner end of the movable convex plate is provided with a movable rod. A pair of guide rods are respectively arranged on both sides of the lower end of the feeding shell. A movable side plate is sleeved on the guide rods on the same side. A pair of L-shaped plates are arranged on the movable side plate. The L-shaped plates are located below the feeding shell. A concave plate is installed on the outer wall of the movable side plate. An inclined hole is opened at the upper end of the concave plate. The upper end of the inclined hole extends obliquely outwards. The lower end of the inclined hole communicates with a vertical hole. The movable rod moves in the vertical hole and the inclined hole. Through the provided L-shaped plates, they can be inserted into the packaging bag. When the bag mouth of the packaging bag is opened, they can move outwards to ensure that the bag mouth of the packaging bag can be opened. And for the provided cylinder, when it drives the movable frame to move, it can act on the inclined hole through the provided movable rod, and then the L-shaped plates are opened simultaneously. When the L-shaped plates are opened, on the one hand, the limit on the lower end of the hot pot base materials is cancelled, so that the hot pot base materials enter the packaging bag, and on the other hand, the bag mouth can also be opened. And the provided feeding shell plays a role of limiting and constraining the hot pot base materials during feeding, so as to prevent the posture of the hot pot base materials from changing during feeding.

[0006] Furthermore, the lower end of the L-shaped plate is in a wedge-shaped structure, which facilitates sleeving the packaging bag on the vertical section of the L-shaped plate.

[0007] Furthermore, in order to facilitate the sleeving operation of the packaging bag, the projections of the vertical sections of the L-shaped plates at the same end coincide with each other.

[0008] Furthermore, in order to enable the L-shaped plate to quickly achieve the closing operation to limit the lower end of the hot pot base material, a spring is sleeved on the outer end of the guide rod, and a limit nut is provided at the outer end of the spring, and the limit nut is arranged at the outer end of the guide rod.

[0009] Furthermore, in order to completely put the hot pot base material into the packaging bag, a vertical plate is provided on the other side of the moving frame, an inner insertion cylinder is provided at the upper end of the vertical plate, a U-shaped groove is formed in the feeding shell, and the movable part of the inner insertion cylinder passes through the U-shaped groove.

[0010] The advantages of the above technical solutions are as follows:

[0011] The utility model facilitates the packaging operation of the hot pot base material, and during the packaging process, it can limit the hot pot base material to ensure the reliability of feeding, and can also completely open the bag mouth of the packaging bag, thus facilitating the complete packaging operation of the hot pot base material.
