[0034] See Figures 1 to 8A paste filling device includes a base, a hopper 1 fixed to the top wall of the base, and an injection pump 2 at the bottom of the hopper 1. The hopper 1 has two inner cavities, namely a paste storage chamber 11 and a water storage chamber 12.

[0035] The base is provided with a hot water tank 3, to which a water outlet pump 31 is fixedly connected, and the water outlet of the hot water tank 3 is connected to the water inlet of the water outlet pump 31 through a pipe (not shown in the figure). A water inlet joint 13 is provided at the bottom of the hopper 1, and a water outlet joint 14 is provided at the upper part of the hopper 1. Both the water inlet joint 13 and the water outlet joint 14 are connected to the water storage chamber 12. The water inlet joint 13 is connected to the water outlet of the water outlet pump 31 through a pipe (not shown in the figure), and the water outlet joint 14 is connected to the water inlet of the hot water tank 3 through a pipe (not shown in the figure). The hopper 1 is provided with a top cover, to which a stirring motor 15 is fixedly connected, and the stirring motor 15 is provided with a stirring shaft (not shown in the figure), and the stirring shaft extends into the paste storage chamber 11.

[0036] The base is fixedly connected to a frame 4, which is rotatably connected to a bag reel 41. The bag reel 41 is fitted with a packaging bag drum (not shown). A bag folding guide 5 is also fixedly connected to the base. The bag folding guide 5 is a triangular pyramid-shaped sheet with a cavity 52 defined at its rear side. A discharge channel 51 is fixedly connected to the lower end of the bag folding guide 5. The discharge port of the injection pump 2 is connected to a discharge pipe 21, which extends into the cavity 52 of the bag folding guide 5. Two limiting clamps 61 are provided on the front side of the base. The inner walls of these clamps 61 are provided with U-shaped heat-molding strips 62. When combined, these two U-shaped heat-molding strips 62 form a U-shaped cavity 68. The discharge channel 51 is located at the upper opening of the U-shaped cavity 68.

[0037] Specifically, a vertical rotating shaft 63 is provided within the base, to which an upper cam 64 and a lower cam 65 are fixedly connected. A right swing arm 66 and a left swing arm 67 are hingedly connected to the base. The front end of the right swing arm 66 is fixedly connected to the right-side limiting clamp 61, and the rear end of the right swing arm 66 is provided with a right roller 661, which maintains contact with the side wall of the upper cam 64. The front end of the left swing arm 67 is fixedly connected to the left-side limiting clamp 61, and the rear end of the left swing arm 67 is provided with a left roller 671, which maintains contact with the side wall of the lower cam 65.

[0038] Specifically, the front wall of the bag folding guide 5 gradually narrows from top to bottom, and the left wall and the right wall of the bag folding guide 5 gradually narrow from bottom to top.

[0039] Specifically, see Figure 3 The base is fixed with a longitudinal shaft 71, and a left clamping roller 72 is provided at the front end of the longitudinal shaft 71. The base is fixed with a bag clamping motor 73, and the motor shaft of the bag clamping motor 73 is provided with a right clamping roller 731. The left clamping roller 72 and the right clamping roller 731 can jointly clamp the overlapping edge of the packaging bag.

[0040] Specifically, the base is provided with a vertical screw mechanism 81, which includes a vertical guide rail and a vertical screw. The vertical guide rail is slidably connected to a vertical slide frame 82, which is threadedly connected to the vertical screw. A fixed shear blade 821 is disposed within the vertical slide frame 82. A longitudinal rotating shaft 822 is disposed within the vertical slide frame 82, to which a movable shear blade 823 is fixedly connected. The movable shear blade 823 is offset from the fixed shear blade 821 to leave a bag-passing gap 824, which allows the packaging bag strips to pass through.

[0041] Specifically, a shearing motor 83 is fixedly connected to the outer wall of the vertical sliding frame 82 , and a motor shaft of the shearing motor 83 is coaxially fixedly connected to the longitudinal rotating shaft 822 .

[0042] Specifically, the base is fixed with a sliding bucket, which is tilted and located below the bag passing gap 824 .

[0043] Specifically, the hot water tank 3 is provided with a tank cover at its opening.

[0044] The working principle of this utility model paste filling equipment is as follows:

[0045] The paste storage chamber 11 contains a paste with high viscosity and poor fluidity. A water storage chamber 12 is located outside the paste storage chamber 11. A water outlet pump 31 pumps hot water from the hot water tank 3 into the bottom of the water storage chamber 12. The water in the water storage chamber 12 then returns to the hot water tank 3 through the water outlet connector 14, completing the water circulation process. A heating wire is installed within the hot water tank 3 to maintain the water temperature.

[0046] The hot water in the water storage chamber 12 transfers heat to the paste storage chamber 11, causing the paste in the paste storage chamber 11 to heat up and improve the paste's fluidity. The bottom outlet of the paste storage chamber 11 is connected to the feed port of the injection pump 2. The injection pump 2 pumps the paste in the paste storage chamber 11 into the rear cavity 52 of the folding bag guide 5 (see Figure 5 ), and then flows into the discharge channel 51.

[0047] The frame 4 is rotatably connected to a bag reel 41, which is sleeved with a bag roll (not shown), and the bag roll is wound with a bag belt, which slides over the front wall of the bag folding guide 5 (such as Figure 5 As shown in FIG, the packaging bag belt is folded in half by the shape of the bag folding guide 5. The belt section folded in half wraps the discharge channel 51 and passes between the two limiting clamping plates 61.

[0048] The upper cam 64 and the lower cam 65 periodically drive the two limiting clamps 61 to swing together. When the two limiting clamps 61 overlap, the two U-shaped heat-pressing strips 62 overlap, forming a U-shaped cavity 68. The two U-shaped heat-pressing strips 62 heat up, hot-pressing a U-shaped sealing edge on the folded-in-half strip, forming a bag body. Then, the discharge channel 51 injects the paste into the bag body.

[0049] The left clamping roller 72 and the right clamping roller 731 jointly clamp the rear edge of the half-folded belt segment, thereby intermittently pulling the bag segment down by the height of a bag body. In this way, each time the U-shaped profiling hot pressing strip 62 is hot pressed, the bottom edge of the U-shaped profiling hot pressing strip 62 just seals the bag opening of the last hot pressed bag body, making the last hot pressed bag body completely sealed.

[0050] Then, the completely sealed bag body enters the bag gap 824, and the movable scissor blade 823 and the fixed scissor blade 821 jointly cut the bag body from the bag belt to form an independently packaged product.

[0051] By providing a water storage chamber 12 outside the paste storage chamber 11 and continuously heating the paste storage chamber 11 with circulating hot water, the paste in the paste storage chamber 11 maintains high fluidity, allowing it to be smoothly injected into the bag folding guide 5 by the injection pump 2. The shape of the bag folding guide 5 guides the flat packaging bag strip to a semi-folded strip section, forming the initial shape of the bag body. The semi-folded strip section is heat-sealed by two U-shaped contoured heat press strips 62 to form the bag body. The bag body can now be filled with paste. The filled bag body is then sealed during the next heat press and can then be cut to form an individually packaged product.

[0052] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
