Description

Technical Field

[0001] The utility model relates to the technical field of quantitative automatic packaging machines, in particular to a quantitative packaging machine. Background Art

[0002] A quantitative packaging machine is a type of automated packaging equipment widely used in industries such as food, feed, grain, seeds, and chemicals. It is computer-controlled and integrates automatic feeding, filling, and bagging. The machine consists of a feeder, a weighing hopper, a drop hopper, a frame, and a control system. The feeder comes in various types depending on the material: deadweight, spiral, belt, and vibrating. The weighing hopper is used to weigh materials, allowing for transitional storage and convenient emptying. The drop hopper has both a bag-clamping function and a funnel-like effect, facilitating the flow of material from the weighing hopper into the bag. The frame stabilizes the entire machine, and the control system controls the entire mechanical system according to a pre-programmed procedure. However, existing automatic quantitative packaging machines can cause wrinkles to form when sealing the bag, resulting in a loose seal that can lead to leakage or contamination of the bag's contents. Therefore, there is a need for a quantitative packaging machine that can smooth out wrinkles and improve sealing quality. Utility Model Content

[0003] In response to the above technical problems, the utility model provides a quantitative packaging machine that can flatten wrinkles and improve the sealing quality when sealing the packaging bag, so as to solve the problem that the existing packaging bags may shrink, resulting in loose sealing, causing the contents of the packaging bag to leak or be contaminated.

[0004] In order to solve the above technical problems, the quantitative packaging machine described in the present invention includes a fuselage, a feed hopper is provided at the upper end of the fuselage, the lower end of the feed hopper is connected to the feeding device, the lower end of the feeding device is provided with a feeding hopper, the feeding hopper is fixedly connected to the fuselage, bag clamps are provided on both sides of the lower part of the feeding hopper, and a sealing machine is provided at the bottom, the bag clamp and the sealing machine are fixedly connected to the fuselage, the two sides of the lower part of the feeding hopper are fixedly connected to the connecting rod, the bottom of the outer end of the connecting rod is fixedly connected to the supporting mechanism, the supporting mechanism includes a spring, a telescopic rod, and a telescopic sleeve rod, the telescopic sleeve rod is fixedly connected to the connecting rod, the upper end of the telescopic rod is slidably arranged in the telescopic sleeve rod, the spring is provided in the telescopic sleeve rod, the upper end of the spring is fixedly connected to the connecting rod, and the lower end is fixedly connected to the telescopic rod, and the contact surface between the pressure strip on the sealing machine and the telescopic rod is an inclined surface.

[0009] Compared with the prior art, the present invention has the following advantages:

[0010] The utility model has connecting rods fixedly connected to both sides of the lower part of the feeding hopper, and the bottom ends of the outer ends of the connecting rods are fixedly connected to a supporting mechanism, which can flatten the packaging bag after the back sealing is completed.

[0017] It should be noted that the feeding device 3, bag clamp 5 and sealing machine 10 in the present invention are existing devices. The feeding device 3 is composed of a cutting hopper, a cutting door, pneumatic components, a weighing sensor, a weighing hopper and other structures. The bag clamp is composed of pneumatic components, a manipulator and a heater. The sealing machine 10 is mainly composed of a sliding rail, a movable plate, a pressure strip 1001, a heat sealing strip and other structures. The specific structure will not be described in detail in this article.

[0018] In order to facilitate the unloading and forming of the packaging bag 15, a support frame 11 is fixedly connected to the upper end of the fuselage 1, and a loading shaft 16 is rotatably connected to the support frame 11. The loading shaft 16 is sleeved with the packaging bag 15, and one end of the loading shaft 16 is connected to the output end of the motor 14. A bending rod 12 is fixedly connected to the middle part of the support frame 11, and a limiting rod 13 is rotatably connected to the bending rod 12.

[0019] In order to enhance the stability of the feed hopper 2 , a support leg 19 is fixedly connected to the upper end of the body 1 , and the support leg 19 is fixedly connected to the feed hopper 2 via a fixing rod 18 .

[0020] In order to conveniently define the position of the packaging bag 15 and facilitate sealing the back of the packaging bag 15, a plurality of limiting slot plates 17 are arranged at intervals on the outside of the feeding hopper 4, and the limiting slot plates 17 are fixedly connected to the fuselage 1.

[0021] In order to reduce the impact on the packaged product when it falls off, a buffer plate 6 is arranged obliquely below the sealing machine 10. The upper end of the buffer plate 6 is fixedly connected to the fuselage 1, and the middle part of the buffer plate 6 is fixedly connected to the fuselage 1 through a reinforcing rib 7.

[0022] The working process of this embodiment is as follows:

[0023] One end of the packaging bag 15 sleeved on the loading shaft 16 is pulled down, bypasses the limit rod 13 and continues to be pulled down, then passes through the limit slot plate 17, and descends to the position of the bag clamp 5 for back sealing. The loading shaft 16 is driven to rotate by the control motor 14, so that the sealed part of the back of the packaging bag 15 is then descended to the sealing machine 10 for bottom sealing, and then continues to descend to the required length of the single packaging bag 15. At this time, the material enters the feeding device 3 through the feed hopper 2. The feeding device 3 is divided into three feeding modes: fast, medium and slow. When the material weight reaches the fast feeding set value, the fast feeding is stopped and the medium feeding is maintained; when the material weight reaches the fast feeding set value, the medium feeding is stopped and the slow feeding is maintained; when the material weight reaches the final set value, the feeding door is closed to complete the dynamic weighing process. The weighed material falls through the feed hopper 4 into the packaging bag 15 after the back and bottom seals are completed. The sealing machine 6 seals and cuts the packaging bag 15 containing the material, and the packaged product falls along the buffer plate 6. During this period, when the sealing machine 10 seals the packaging bag 15, the pressure bar 1001 in the sealing machine 10 contacts the telescopic rod 903 when approaching the packaging bag 15, and pushes the telescopic rod 903 upward along the direction of the telescopic sleeve rod 901, and then quickly presses the packaging bag 15 to seal it. When the pressure bar 1001 moves away from the packaging bag 15, the telescopic rod 903 is reset under the action of the spring 902, so as to achieve the purpose of flattening the wrinkles when the packaging bag 15 is sealed.
