Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of packaging-related technology, and more specifically, to a packaging device for food ingredient packets. Background Technology

[0002] In industries such as convenience food and condiment processing, the packaging of food ingredients (especially powders such as spice powders and seasoning powders) is a crucial step in the production process, and its efficiency and metering accuracy directly determine product quality and production costs. However, existing packaging equipment suffers from two major drawbacks: low packaging efficiency and difficulty in accurately controlling the amount of powder entering the bag, which severely restricts the industry's development.

[0003] Current mainstream equipment mostly adopts single-station intermittent operation, which requires sequential completion of steps such as bag picking, bag opening, and filling. The switching time between each process is relatively high, making it difficult to meet the high-speed requirements of modern production lines. More importantly, due to the high fluidity and dust-generating characteristics of powder materials, existing metering devices (such as screw and vibratory types) have significant errors in controlling the amount of material entering the bag.

[0004] This precision defect leads to two types of problems: first, overfilling results in raw material waste, with annual losses reaching several tons; second, underfilling triggers quality complaints. Furthermore, to correct measurement deviations, operators need to frequently stop the machine for calibration, further reducing equipment operating efficiency. In multi-variety, small-batch production scenarios, parameter adjustments and cleaning of metering components during equipment changeovers are time-consuming, exacerbating capacity losses. Therefore, developing food ingredient packaging equipment that combines efficient continuous operation with accurate metering has become a pressing technical challenge for the industry. Utility Model Content

[0005] To overcome the above-mentioned defects, embodiments of this disclosure provide a packaging device for food ingredients, which solves the technical problem that the switching time of each process in the prior art is high and it is difficult to match the high-speed requirements of modern production lines.

[0006] According to one aspect, at least one embodiment of the present disclosure provides a packaging apparatus for food ingredient packets, comprising: The frame and the top frame, wherein the top frame is fixed to the top of the frame; A bag-opening and feeding assembly is disposed in the top frame; A storage box and a bag-in-the-box assembly are provided. The storage box is fixed inside the frame. The top and bottom of the storage box are open structures. The bag-in-the-box assembly is provided on the storage box and the frame. The bag inlet assembly includes a base frame, which is fixed to the bottom of the frame body. A stud is vertically rotatably connected to the bottom of the base frame, and the stud is driven to rotate by electricity. A pair of telescopic rods are provided on the base frame, and a rectangular plate is connected to the output end of the telescopic rods.

[0007] As a further technical solution, springs are provided at the four corners of the rectangular plate, a support plate is provided at the upper end of the spring, and an internally threaded tube is provided at the bottom of the rectangular plate. The internally threaded tube is connected to the stud by a threaded engagement.

[0008] As a further technical solution, the tray is located inside the storage box, and both ends of the top of the storage box are rotatably connected to pressure wheels. A pair of push rollers are provided on the top of the frame, and the push rollers are all electrically driven to rotate.

[0009] As a further technical solution, a flip plate is rotatably connected to the frame body via a rotating shaft. The flip plate is flipped by electric drive. Both ends of the flip plate surface are provided with clamps connected by vertical linear drive, and the clamps surface is provided with openings.

[0010] As a further technical solution, the bag opening and feeding assembly includes a double-sided baffle, which is fixed to the bottom of the frame body. A pair of first cylinders are vertically connected to the bottom of the double-sided baffle, and a second cylinder is horizontally connected to the output end of the first cylinder. A suction nozzle is provided at the output end of the second cylinder.

[0011] As a further technical solution, a third cylinder is provided on the top of the top frame, and the output end of the third cylinder is connected to a hopper. A switch baffle is provided inside the hopper and is rotatably connected by a pin. A conveyor belt is provided at the bottom of the base frame.

[0012] As a further technical solution, the top plane of the storage box is slightly higher than the surface of the flip plate.

[0013] As a further technical solution, the flipping plate is electrically driven to flip at an angle of 90°.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: 1. In this disclosure, the bag feeding assembly solves the problem of time-consuming process changeover through an automated bag feeding design. The stud and telescopic rod work together to drive the pallet to rise and fall smoothly, adapting to different stacking heights; the push roller and pressure roller ensure continuous bag supply and avoid jamming; the flipping plate rotates 90° and works with the clamping plate to quickly change the bag's posture. This structure reduces manual bag handling and positioning time, improves feeding continuity, and enables the equipment to match the pace of high-speed production lines, adapting to the efficient conveying needs of multi-specification packaging bags.

[0015] 2. In this disclosure, the bag opening and feeding assembly solves the problems of unstable bag opening and feeding deviation in traditional packaging through precise and coordinated operation. The suction nozzle's negative pressure adsorption reliably opens the bag, avoiding mechanical damage; the feeding hopper and switch baffle work together to achieve quantitative dispensing, reducing powder waste; multiple cylinders work together to control the bag opening and feeding rhythm, ensuring precise action coordination.

[0024] like Figures 1-4 As shown, it illustrates a packaging apparatus for a food ingredient packet according to an embodiment of the present disclosure, comprising: The frame and the top frame, wherein the top frame is fixed to the top of the frame; A bag-opening and feeding assembly is disposed in the top frame; A storage box and a bag-in-the-box assembly are provided. The storage box is fixed to the frame body. The top and bottom of the storage box are open structures. The bag-in-the-box assembly is provided on the storage box and the frame body. The bag-feeding assembly includes a base frame fixed to the bottom of the frame body. A stud is vertically rotatably connected to the bottom of the base frame, and the stud is electrically driven to rotate. A pair of telescopic rods are provided on the base frame, and a rectangular plate is connected to the output end of each telescopic rod. Springs are provided at the four opposite corners of the rectangular plate, and a support plate is provided at the upper end of each spring. An internally threaded tube is provided at the bottom of the rectangular plate, and the internally threaded tube is connected to the stud via a threaded engagement. The support plate is located inside the storage box. Pressure rollers are rotatably connected to both ends of the top of the storage box. A pair of push rollers are provided at the top of the frame body, and both push rollers are electrically driven to rotate. A flipping plate is rotatably connected to the frame body via a rotating shaft. The flipping plate is electrically driven to flip. Clamping plates are provided at both ends of the flipping plate surface, and the clamping plates have openings on their surfaces.

[0025] In some examples, a bag-feeding assembly is designed to achieve orderly supply and angle conversion of packaging bags in conjunction with packaging feeding. This assembly includes a base frame at the bottom of the frame as a supporting foundation. The studs at the bottom of the inner frame rotate vertically via bearings, driven by a motor, and engage with the internal threaded pipe at the bottom of the rectangular plate to form a lifting transmission structure. A pair of telescopic rods are symmetrically distributed on the base frame, with their output ends connected to the rectangular plate to ensure smooth lifting of the rectangular plate. The upper ends of the springs at the four corners of the rectangular plate are connected to the trays, which buffer the load-bearing pressure of the trays. The trays are located inside the storage box for stacking packaging bags. The clamping wheels at both ends of the top of the storage box rotate relative to each other to clamp the top edge of the packaging bags. A pair of push rollers at the top of the frame are driven by a motor to rotate, pushing the packaging bags horizontally towards the flipping plate through friction. The flipping plate inside the frame rotates via a rotating shaft and is driven by a motor to achieve horizontal and vertical flipping. The clamps at both ends of the surface are driven by a vertical linear drive device (such as a cylinder) to clamp the edges of the packaging bags. The openings on the surface of the clamps provide space for subsequent bag opening operations.

[0026] During operation, the rotating stud drives the rectangular plate upward, and the pallet pushes the packaging bags in the storage box upward. The top layer of packaging bags, through the cooperation of the pressure roller and the push roller, is pushed horizontally into the tilting plate. The clamping plate, under the action of the drive device, clamps the packaging bags, and the tilting plate rotates to a vertical position, completing the conversion of the packaging bags from horizontal conveying to vertical positioning. The spring-supported pallet adapts to changes in the stacking height of the packaging bags, ensuring stable pushing pressure. The coordinated conveying of the push roller and the pressure roller ensures that the packaging bags are supplied one by one, avoiding stacking. The tilting plate's posture conversion, combined with the clamping plate's gripping, provides a vertically stable operating posture for subsequent bag opening and unloading. The guiding function of the telescopic rod ensures precise pallet lifting and lowering, improving conveying reliability. This component provides a continuous and stable supply of packaging bags for food ingredient packaging through automated conveying and posture conversion.

[0027] like Figures 1-4 As shown in the figure, the bag opening and feeding assembly proposed in this embodiment includes a double-sided baffle, which is fixed to the bottom of the frame body. A pair of first cylinders are vertically connected to the bottom of the double-sided baffle. A second cylinder is horizontally connected to the output end of the first cylinder. A suction nozzle is provided at the output end of the second cylinder. A third cylinder is provided at the top of the top frame. A feeding hopper is connected to the output end of the third cylinder. A switch baffle is provided in the feeding hopper and rotatably connected by a pin. A conveyor belt is provided at the bottom of the base frame.

[0028] In some examples, a bag-opening and unloading assembly is designed to achieve precise opening of the packaging bags and filling of powder. This assembly includes a pair of first cylinders vertically mounted on double-sided baffles at the bottom of the frame, with a second cylinder horizontally connected to the output end, allowing for horizontal extension and retraction. The suction nozzle at the output end of the second cylinder is connected to a negative pressure device to adsorb the sidewalls of the packaging bag. A third cylinder at the top of the frame connects to a hopper, driving the hopper to rise and fall. A switch baffle inside the hopper rotates via a pin, controlled by a drive device to open and close, controlling powder discharge. A conveyor belt at the bottom of the double-sided baffles transports the filled packaging bags to the next process.

[0029] During operation, when the flipping plate brings the packaging bag to a vertical position and the clamping plates hold it on both sides, the second cylinder drives the suction nozzle to extend into the opening of the clamping plates, adsorbing the inner walls of both sides of the packaging bag. The first cylinder drives the second cylinder to move in the opposite direction, opening the packaging bag. Subsequently, the third cylinder drives the feeding hopper to descend to the bag opening, the switch baffle rotates and opens, and the powder falls from the feeding hopper into the packaging bag. After feeding is completed, the switch baffle closes, the feeding hopper rises back to its original position, the suction nozzle releases the negative pressure, and the packaging bag is filled and output with the conveyor belt. The negative pressure suction bag opening avoids mechanical damage to the packaging bag and is suitable for packaging bags of different materials; the precise control of the switch baffle ensures quantitative powder feeding, reducing waste; the coordinated action of multiple cylinders matches the bag opening and feeding rhythm, improving packaging efficiency. This component achieves efficient filling of food ingredient packages through automated bag opening and precise feeding, ensuring packaging quality.

[0030] For example, such as Figure 4 As shown, the top plane of the storage box is slightly higher than the surface of the flip plate.

[0031] In some examples, the top plane of the storage box is slightly higher than the surface of the flipping plate, which allows the packaging bag to be pushed more smoothly from the storage box to the flipping plate using the height difference. When the push roller pushes the packaging bag, this height design reduces obstruction at the junction of the two, avoids the packaging bag edges getting stuck or wrinkled, and ensures that the packaging bag enters the flipping plate with a flat posture, providing a good foundation for subsequent clamping and flipping operations, and improving the smoothness of bag entry.

[0032] For example, such as Figure 4 As shown, the flip plate is electrically driven to flip at an angle of 90°.

[0033] In some examples, the flip plate is electrically driven to rotate at a 90° angle, precisely enabling the packaging bag to transition from a horizontal to a vertical position. The 90° rotation angle ensures the bag opening faces upwards, precisely aligning with the suction nozzle and hopper of the bag opening and feeding assembly. This facilitates the suction nozzle's insertion into the bag opening and the hopper's feeding, ensuring accurate and efficient bag opening and feeding processes that meet the operational requirements of the packaging workflow.

[0034] In actual use: The stacked packaging bags inside the storage box are supported by a pallet. The rotation of the stud drives the rectangular plate to rise, and the spring buffer adjusts the height. The push roller and the pressure wheel work together to horizontally feed the top layer of packaging bags into the flipping plate. The clamping plate vertically drives and clamps the bag body. The flipping plate rotates 90° so that the bag opening faces upward. The first cylinder of the double-sided baffle drives the second cylinder to move. The suction nozzle extends into the opening of the clamping plate to suck up the bag wall and pulls in the opposite direction to open the bag opening. The third cylinder drives the hopper to descend to the bag opening. The switch baffle rotates to release the powder. After filling is completed, the hopper resets, the clamping plate releases, and the packaging bag falls into the conveyor belt for transportation. The entire process is seamless and requires no manual intervention.
