Description

Technical Field

[0001] This utility model relates to the field of filling or packaging equipment technology, specifically to a packaging device for processing organic-inorganic compound fertilizer with anti-collision function. Background Technology

[0002] With the advancement of agricultural modernization, organic-inorganic compound fertilizers have become an indispensable type of fertilizer in agricultural production due to their multiple advantages, including comprehensive nutrients, long-lasting effects, and soil improvement. Compound fertilizer processing enterprises generally use automated packaging equipment to complete the mixing and filling operations of fertilizers. These machines typically include a mixing area and a packaging area. The mixing area is responsible for mixing organic and inorganic raw materials evenly in a certain proportion, while the packaging area realizes the quantitative filling and sealing of the mixed fertilizer.

[0003] In the fertilizer filling stage, the packaging bag support structure of traditional equipment is mostly fixed. When the fertilizer falls from the guiding component into the packaging bag, as the amount of fertilizer in the bag increases, there are differences in gravitational potential energy due to the falling distance at the beginning and end. Due to the large differences in the density, shape and flowability of fertilizer particles, problems such as deviation and uneven material distribution are prone to occur. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a packaging device for processing organic-inorganic compound fertilizers with anti-collision function. The device includes a mixing area and a packaging area. The mixing area has an inclined mixing cylinder with multiple feed hoppers mounted on its upper end. A rotating shaft is rotatably connected within the mixing cylinder, and a mixing plate is fixed to the outer side of the shaft. The packaging area has a base plate with three anti-collision plates fixed to its top. These three anti-collision plates are U-shaped, and an adapting plate is slidably connected within the space enclosed by them. A linear actuator is mounted on the base plate, and its telescopic end is fixed to the bottom of the adapting plate via a connecting panel. A rectangular opening frame is positioned above the anti-collision plates, fixed to them via connecting arms. The opening frame has an opening in the middle for fertilizer to pass through, and four clamps are fixed to the bottom of the opening frame in all directions. The mixing cylinder has an opening at its lower end, and a guide component extending above the opening frame is connected to this lower end.

[0005] Furthermore, electric telescopic rods are installed on the outer walls of the two opposing anti-collision plates. The output end of the electric telescopic rods faces away from the anti-collision plates. A vertical plate is fixed to the telescopic end of the electric telescopic rod. A hot-press mounting rod is fixed to the side of the vertical plate near the anti-collision plate. A hot-press plate is installed at the end of the hot-press mounting rod. Through slots are opened on the two connecting arms for the two hot-press plates to pass through.

[0006] Furthermore, the material guiding component includes a material guiding cone hopper fixed to the lower end of the mixing cylinder, and an L-shaped connecting pipe fixed to the lower end of the material guiding cone hopper, with the lower end of the connecting pipe positioned directly above the opening frame.

[0007] Furthermore, the shaft extends beyond the mixing drum at one end, and a gear reducer is connected to the end of the shaft. The input end of the gear reducer is connected to a three-phase asynchronous motor via a coupling.

[0008] Furthermore, a weight sensor is mounted on the top of the adaptation plate, and the weight sensor is electrically connected to the linear driver.

[0009] Furthermore, the mixing plate has multiple material passage holes.

[0010] The beneficial effects of this utility model are as follows: 1. By setting up a linkage mechanism consisting of a vertically movable adaptive plate, a weight sensor, and a linear actuator, the fertilizer's falling distance is dynamically adjusted. During the filling process, the linear actuator slowly retracts based on the signal detected by the weight sensor, causing the packaging bag to move synchronously downwards. This ensures that the fertilizer falls at a relatively consistent distance each time, effectively preventing splashing and deviation due to excessive gravitational potential energy from a large falling distance, or overflow due to a small falling distance. Simultaneously, a bumper plate prevents the fertilizer from shifting outwards.

[0011] 2. Four clamps open the packaging bag to ensure smooth filling of the fertilizer and prevent one-way displacement of the fertilizer due to a small landing area. The heat-sealing of the hot press plate is integrated with the device, eliminating the need for additional multiple transfer processes. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0016] The present invention will be further described below with reference to the accompanying drawings: A packaging device for processing organic-inorganic compound fertilizers with anti-collision function, such as Figure 1 , Figure 2 and Figure 3 As shown, the system includes a mixing area and a packaging area. The mixing area has a mixing cylinder 1 installed at an angle. Multiple feed hoppers 2 are installed at the top of the upper end of the mixing cylinder 1. A rotating shaft 3 is rotatably connected inside the mixing cylinder 1. A mixing plate 4 is fixed to the outer side of the rotating shaft 3, and multiple material passage holes are opened on the mixing plate 4. The upper end of the rotating shaft 3 extends outside the mixing cylinder 1, and a gear reducer 5 is connected to the end of the rotating shaft 3. The input end of the gear reducer 5 is connected to a three-phase asynchronous motor 6 via a coupling. The packaging area has a base plate 7, and three anti-collision plates 8 are fixed to the top of the base plate 7. The three anti-collision plates 8 are... The body is U-shaped, and an adaptation plate 9 is slidably connected within the space enclosed by three anti-collision plates 8. A linear actuator 10 is installed on the bottom plate 7. The telescopic end of the linear actuator 10 is fixed to the bottom of the adaptation plate 9 through a connecting panel. A weight sensor 20 is installed on the top of the adaptation plate 9, and the weight sensor 20 is electrically connected to the linear actuator 10. A rectangular opening frame 11 is provided above the anti-collision plates 8. The opening frame 11 is fixed to the anti-collision plates 8 through a connecting arm 13. The opening frame 11 has an opening in the middle for fertilizer to pass through. Four clamps 12 are fixed at the bottom of the opening frame 11 in all directions.

[0017] The inclined mixing cylinder 1 and the internal mixing plate 4 in the mixing area effectively promote uniform mixing of fertilizers, ensuring full integration of organic and inorganic fertilizers. The anti-collision plate 8 and adapting plate 9 in the packaging area provide stable support and protection for the packaging bag, preventing fertilizer from shifting or splashing due to collisions during filling. The linear actuator 10, electrically connected to the weight sensor 20, enables dynamic adjustment of the packaging bag position during filling, ensuring uniform fertilizer filling.

[0018] like Figure 2 and Figure 3 As shown, in this embodiment, the lower end of the mixing cylinder 1 is open, and a material guiding component extending above the opening frame 11 is connected to the lower end of the mixing cylinder 1. The material guiding component includes a material guiding cone hopper 18 fixed to the lower end of the mixing cylinder 1, and an L-shaped connecting pipe 19 fixed to the lower end of the material guiding cone hopper 18. The lower end of the connecting pipe 19 is directly above the opening frame 11. The design of the material guiding cone hopper 18 helps to concentrate and guide the flow of the mixed fertilizer, reducing fertilizer spillage during transportation. The structure of the L-shaped connecting pipe 19 allows the fertilizer to fall accurately into the packaging bag inside the opening frame 11.

[0019] like Figure 3 As shown, in this embodiment, electric telescopic rods 14 are installed on the outer walls of two opposing anti-collision plates 8. The output end of the electric telescopic rod 14 faces away from the anti-collision plate 8. A vertical plate 15 is fixed to the telescopic end of the electric telescopic rod 14. A heat-pressing mounting rod 16 is fixed to the side of the vertical plate 15 near the anti-collision plate 8. A heat-pressing plate 17 is installed at the end of the heat-pressing mounting rod 16. Through slots are provided on the two connecting arms 13 for the two heat-pressing plates 17 to pass through. The telescopic movement of the electric telescopic rod 14 drives the heat-pressing plate 17 to move, realizing rapid heat sealing of the packaging bag opening.

[0020] The working principle of this utility model is as follows: The three-phase asynchronous motor 6 drives the gear reducer 5 via a coupling to increase torque, which in turn drives the rotating shaft 3 to rotate, causing the mixing plate 4 to rotate accordingly. The beating action of the mixing plate 4 causes the fertilizer particles to tumble repeatedly inside the mixing drum 1, while the material passage holes ensure that the fertilizer is evenly distributed in different positions within the mixing drum 1, achieving thorough mixing of organic and inorganic fertilizers. The rotation speed of the rotating shaft 3 is adjusted by the gear reducer 5 to adapt to the mixing requirements of different fertilizers.

[0021] The mixed fertilizer enters the upper part of the opening frame 11 from the lower end of the mixing cylinder 1 through the guide cone hopper 18 and the L-shaped connecting pipe 19. After the packaging bag is placed on the adapting plate 9, the bag opening is clamped by four clamps 12, opening the bag. The weight sensor 20 monitors the weight change of the fertilizer inside the packaging bag in real time, and sends a signal to the linear actuator 10. The actuator contracts, causing the bottom of the packaging bag to gradually move downward (initially, the packaging bag is in a pleated state, so that the distance between the bottom of the packaging bag and the fertilizer is not too high, reducing the gravitational potential energy of the fertilizer, and thus preventing the fertilizer from shifting due to excessive gravitational potential energy). During the downward movement, the distance the fertilizer falls is basically consistent each time, so that the distance is not too long and the gravitational potential energy is too high, nor too short and the fertilizer overflows. The anti-collision plate 8 restricts the lateral displacement of the fertilizer, and the fertilizer always falls accurately into the packaging bag.

[0022] After filling is complete, release the two clamps 12 on the left and right sides. The electric telescopic rods 14 on the outer walls of the two anti-collision plates 8 retract, causing the heat-pressing plate 17 to move towards the top of the packaging bag. After the heat-pressing plate 17 contacts the opening of the packaging bag, it seals the opening through heat sealing. After heat sealing is complete, release the front and rear clamps 12, and the packaging bag can be removed from the side without the anti-collision plates 8.

[0023] It is worth noting that the coordination between the weight sensor 20 and the linear actuator 10 mainly relies on a signal processing and control system, which is an existing control method, briefly described below. The weight sensor 20 detects changes in the weight of the fertilizer inside the packaging bag, converts the weight signal into an electrical signal, and after signal amplification and analog-to-digital conversion, transmits it to the control module. The control module embeds a PID control algorithm, calculates the adjustment amount based on the difference between the preset weight target value and the actual detected weight value, and sends the adjustment signal to the drive module. The drive module amplifies the control signal and converts it into a drive signal executable by the linear actuator 10, controlling the extension and retraction of the linear actuator 10.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
