[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] As shown in the figure, a quantitative dispensing and venting sealing integrated machine includes a box 1 with front and rear openings. A feeding hopper 2 is provided on the top of the box 1. Two gripper mechanisms that can move horizontally relative to each other and longitudinally are provided below the top plate of the box 1. The two gripper mechanisms are located on both sides of the lower part of the feeding hopper 2. A support frame 6 that can move vertically is provided on the upper side of the bottom plate 601 of the box 1. A flip plate 602 that can rotate along the axis is provided on the upper side of the support frame 6. Two strip heat sealing plates 4 that can move relative to each other are provided on the front and rear sides of the box 1. The heat sealing plates 4 are located between the support frame 6 and the gripper mechanisms. A vacuum pump 20 is fixedly connected to the top of the box 1. An exhaust pipe 21 connected to the vacuum pump 20 is provided at the bottom of the top plate of the box 1 near the outlet of the feeding hopper 2. In this embodiment, a flow meter and a solenoid valve are installed at the bottom outlet of the feed hopper 2 to control the amount of jam. The packaging bag is supported by the support frame 6. The opening of the packaging bag can be manually opened and placed on the support frame 6. Although this still requires manual operation, it greatly reduces the intensity and time of manual operation compared to manually opening the bag during the entire filling process. The opening of the packaging bag is gripped and opened by the gripper mechanism. After the jam and other materials are bagged by the feed hopper 2, the support frame 6 moves down slightly, causing the packaging bag containing jam to move down as well. This causes the gripper mechanism to move up relative to the packaging bag. At this time, the vacuum pump 20 is started to extract the air from the packaging bag through the exhaust pipe 21, and the heat sealing plate 4 is moved to seal the opening of the packaging bag. After sealing, the gripper mechanism is released, and the flipping plate 602 is flipped to one side at a certain angle to tilt, so that the packaged bag containing food and sealed slides to the outside of the box 1 and falls onto the conveyor belt for transportation.

[0029] The feeding hopper 2 includes an inverted conical first feeding section 201, a tubular second feeding section 202, and a discharge port 203 arranged sequentially from top to bottom. An installation hole is provided on the top plate of the housing 1. The first feeding section 201 is located on the upper side of the top plate of the housing 1. The second feeding section 202 is fixed in the installation hole. The discharge port 203 and the connection between the second feeding section 202 are configured as an inverted conical surface structure.

[0030] The feed hopper 2 is designed with a double-layer structure and a heating chamber between the two layers. A heating coil is installed in the heating chamber. By controlling the temperature of the heating coil, different degrees of heating are achieved, so that the jam and other materials in the feed hopper 2 are kept at a suitable temperature and are less likely to solidify and block the discharge port 203.

[0031] A cover plate 3 is fixedly connected to the top opening of the first feeding section 201. A first motor 17 is fixedly connected to the upper side of the cover plate 3. A rotating shaft 18 is vertically provided on the lower side of the cover plate 3 and is fixedly connected to the output shaft of the first motor 17. The rotating shaft 18 extends through the first feeding section 201 to the lower part of the second feeding section 202. Multiple stirring rods 1801 are fixedly connected to the rotating shaft 18. A feed inlet 301 is provided on the cover plate 3 for feeding materials into the feeding hopper 2. In this embodiment, a mounting edge 204 is fixedly connected to the top opening of the first feeding section 201 in a horizontal direction. The cover plate 3 and the mounting edge 204 are fixed together by multiple bolt and nut pairs. The stirring rods 1801 in the first feeding section 201 are arranged to decrease in length from top to bottom. The stirring rods 1801 in the second feeding section 202 are of the same length, so that they are more compatible with the structure of the feeding hopper 2.

[0032] A bidirectional screw 11 and a guide rod are provided between the left and right side walls of the housing 1, close to the top plate of the housing 1. The bidirectional screw 11 and the guide rod are located on the front and rear sides of the second feeding part 202. A second motor 12 is fixedly connected to the outer side wall of the housing 1 at the location corresponding to the bidirectional screw 11. The output shaft of the second motor 12 is fixedly connected to the bidirectional screw 11. A movable seat 13 is connected between the bidirectional screw 11 and the guide rod at each gripper mechanism. The gripper mechanism includes a finger cylinder 15 containing a bidirectional output shaft and a clamping plate 16 fixedly connected to the output shafts on the left and right sides of the finger cylinder 15. A first telescopic unit 14 is fixedly connected to the bottom of each movable seat 13. A fixing block is fixedly connected to the bottom of the first telescopic unit 14. A finger cylinder 15 is fixedly connected to the bottom of the fixing block.

[0033] The clamping plate 16 includes a connecting part 1601, a transition part 1602, and a clamping part 1603. The connecting part 1601 is vertically fixed to the output shaft of the finger cylinder 15. The transition part 1602 is inclined and located between the connecting part 1601 and the clamping part 1603. The clamping parts 1603 of the two clamping plates 16 are arranged facing each other. The inner side of each clamping part 1603 is provided with an anti-slip pad (not shown in the figure), and the clamping part 1603 is designed with an inverted triangular structure to facilitate the support of the packaging bag during plastic sealing after bagging. In this embodiment, the finger cylinder 15 can make the clamping parts 1603 of the two clamping plates 16 stick together tightly, ensuring that the clamping parts 1603 can stably clamp the packaging bag. In this embodiment, the clamping part 1603 is provided with an inverted triangular structure. When clamping and supporting the packaging bag, it ensures that the opening of the packaging bag is opened, so that materials such as jam can enter from the feed hopper 2. When plastic sealing is required, the clamping part 1603 moves upward relative to the packaging bag. During this process, the contact width between the clamping part 1603 and the packaging bag becomes narrower and narrower, which makes it easier to perform plastic sealing.

[0034] Mounting plates 101 are fixed downwards at both ends of the top plate of the housing 1. A second telescopic unit 5 is fixed on the mounting plate 101 at the corresponding position of the heat-sealing plate 4. The telescopic end of the second telescopic unit 5 is fixed together with the heat-sealing plate 4. In this embodiment, one or two mounting plates 101 are provided on each side, and one second telescopic unit 5 is installed on each mounting plate 101.

[0035] A third telescopic unit 7 is fixedly connected to the upper side of the bottom plate 601 of the housing 1. A support frame 6 is fixedly connected to the top of the third telescopic unit 7. The support frame 6 also includes an L-shaped bottom plate 601. One end of the flip plate 602 is hinged to the vertical section of the bottom plate 601, and the bottom of the other end is provided with a fourth telescopic unit 603. The bottom of the fourth telescopic unit 603 is fixedly connected to the upper side of the horizontal section of the bottom plate 601, and the top abuts against the lower side of the flip plate 602. A limiting frame 6021 is fixedly connected to the lower side of the flip plate 602 along the front-to-back length direction. The telescopic end of the fourth telescopic unit 603 is located inside the limiting frame 6021. The limiting frame 6021 limits the telescopic end of the fourth telescopic unit 603 so that it can only move in the length direction of the limiting frame 6021, preventing it from detaching from the flip plate 602.

[0036] A first connecting rod 8 and a second connecting rod 9 are fixedly connected between the left and right side walls of the housing 1 in front of the third telescopic unit 7. The second connecting rod 9 is located below and in front of the first connecting rod 8. A guide plate 10 that extends forward from the housing 1 is attached to both the first connecting rod 8 and the second connecting rod 9. A limit strip 1001 is fixedly connected to the upper side of the bottom of the guide plate 10. The guide plate 10 is hung on the first connecting rod through the limit strip 1001.

[0037] The box 1 is equipped with casters 19 at the four corners of the bottom for easy movement.

[0038] In this embodiment, the first telescopic unit 14, the second telescopic unit 5, the third telescopic unit 7, and the fourth telescopic unit 603 are all electric telescopic rods or hydraulic cylinders.

[0039] The working process of this embodiment is as follows:

[0040] The support frame 6, containing the packaging bag, is moved upward by the third telescopic unit 7, bringing it closer to the bottom of the feed hopper 2. Then, the second motor 12 drives the bidirectional screw 11 to rotate, moving the two gripper mechanisms to the appropriate positions. The first telescopic unit 14 then drives the gripper mechanisms downward, while the two finger cylinders 15 drive the corresponding clamping plates 16 to grip the corresponding side of the packaging bag, opening the bag. The jam flows from the feed hopper 2 into the packaging bag. During the dispensing process, the third telescopic unit 7 controls the support frame 6 to slowly move downward, allowing more jam to be smoothly filled into the packaging bag and preventing the packaging bag from being damaged when the jam falls directly from a high position. The jam is dropped from the clamping plate 16; after the packaging is completed, the feed hopper 2 is closed, the vacuum pump 20 is started to extract the air from the packaging bag through the exhaust pipe 21, and at the same time the second telescopic unit 5 is started to drive the preheated heat sealing plate 4 to move near the opening of the packaging bag until the two heat sealing plates 4 press against the packaging bag to seal it; after sealing, the heat sealing plate 4 moves away from the packaging bag, and the clamping plate 16 also releases the packaging bag. At this time, the fourth telescopic unit 603 is started to lift the flipping plate 602 so that the flipping plate 602 is tilted at a certain angle, and the packaged jam packaging bag slides from the flipping plate 602 onto the guide plate 10, and then moves out of the box 1 and falls onto the outer conveyor belt for transportation.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
