[0020] See also Figure 1-2 , describe the embodiments of the present invention in detail.

[0021] Embodiment: A soft bag rolling curtain bag dropping mechanism and a multi-layer positioning packaging machine, see Figure 1 As shown, it includes a feed belt 1, and the output end of the feed belt 1 is connected to a roller curtain bag dropping mechanism 2. The roller curtain bag dropping mechanism 2 adopts a roller curtain ball structure to realize the opening and closing of the material bag dropping opening. A step-by-step dropping mechanism 21 for supporting the packaging cardboard is provided directly below the material bag dropping opening of the roller curtain bag dropping mechanism 2.

[0022] In this embodiment, step-by-step feeding (single-layer packaging) is adopted, and the packaging enters the rolling curtain bag-dropping mechanism. The lower packaging cardboard is accurately positioned by the servo system. The rolling curtain opens and the packaging falls on the packaging cardboard. The servo system drives the cardboard to drop to the height of a packaging; step-by-step feeding is adopted again, and the packaging enters the rolling curtain bag-dropping mechanism. The rolling curtain opens and the packaging falls on the cardboard. The servo system drives the cardboard to drop to the height of a packaging; and so on, the multi-layer packaging can be accurately positioned in the carton. The rolling curtain bag-dropping mechanism changes the sliding friction of the traditional slide-type bag-dropping mechanism to rolling friction, which is conducive to the stability of the bag state during the bag-dropping process of lightweight soft packaging, thereby improving the packaging efficiency and the stability of equipment operation.

[0023] In a specific implementation: see Figure 1 and 2 As shown, the rolling curtain type bag dropping mechanism 2 includes a bag dropping frame 3, and the bag dropping frame 3 is open on the front side facing the output end of the feed belt 1 and is used for feeding. A rolling curtain ball assembly 17 is provided on the material bag dropping opening at the bottom of the bag dropping frame 3, and a rolling curtain ball driving assembly for driving the rolling curtain ball assembly 17 to move is provided on the bag dropping frame 3. The rolling curtain ball driving assembly drives the rolling curtain ball assembly 17 to move to open the material bag dropping opening for material dropping or to close the material bag dropping opening.

[0024] Specifically, the bag dropping frame 3 includes two left and right square side panels 4 , and the two square side panels 4 are connected by a support column 5 and a connecting support plate 16 .

[0025] For details, see Figure 1 and 2 As shown, the rolling curtain ball assembly 17 includes a transmission shaft 11, a driving sprocket 12, a driven sprocket shaft 13, a driven sprocket 15, a roller chain 18 and a rolling curtain roller 20. The transmission shaft 11 is supported by a diamond seat bearing 8 at one corner of the two square side panels 4. Driving sprockets 12 are provided at both ends of the transmission shaft 11 and on the inner side of the square side panels 4. The driven sprocket shaft 13 is fixed at the other three corners on the inner side of the two square side panels 4. The driven sprocket shaft 13 supports the driven sprocket 15 through a deep groove ball bearing 14. The driving sprocket 12 and the driven sprocket 15 on the inner side of each of the square side panels 4 are wound with a roller chain 18. The rolling curtain roller 20 is provided with a plurality of rollers 20 and arranged in a row. The two ends of the rolling curtain roller 20 are respectively connected to the roller chains 18 on both sides; the upper inner side of the two square side panels 4 is provided with a guide rail 19 for guiding the roller chain 18, and the roller chain 18 is in the guide rail 19.

[0026] In this embodiment, the above structure enables the roller chain 18 to be expanded into a square structure, so that the rolling roller 20 connected thereto can be in a flat plate shape, thereby forming a good opening and closing control of the material bag dropping opening.

[0027] For details, see Figure 1 and 2 As shown, the roller blind ball drive assembly includes a servo motor 6, a motor seat is provided on the square side panel 4 on one side, the servo motor 6 is fixed on the motor seat, a motor sprocket 7 is provided on the output shaft of the servo motor 6, a motor driven sprocket 9 is fixed on the corresponding end of the transmission shaft 11, and the motor sprocket 7 and the motor driven sprocket 9 are connected by a transmission chain 10.

[0028] In the above embodiment, the servo motor 6 drives the motor sprocket 7 to rotate, the motor sprocket 7 drives the motor driven sprocket 9 to rotate through the transmission chain 10, the motor driven sprocket 9 drives the transmission shaft 11, the driving sprocket 12 on the transmission shaft 11 drives the roller chain 18 to move, and the roller 20 on the roller chain 18 moves to open and close the material bag drop port.

[0029] Specifically, a material baffle 25 is provided at the lower rear portion of the bag dropping frame 3 to block and limit the material that has been moved into position.

[0030] In a specific implementation: see Figure 1 As shown, the step-by-step falling mechanism 21 includes a vertically erected screw rod 22, which is connected to the servo system, a screw rod nut 23 is screwed on the screw rod 22, a packaging cardboard support frame 24 is fixedly connected to the screw rod nut 23, and the packaging cardboard support frame 24 is opposite to the material bag dropping port of the rolling curtain bag dropping mechanism 2.

[0031] In the above embodiment, the servo system drives the packaging cardboard to drop to the height of a package through the screw and the screw mechanism; when the rolling shutter package dropping mechanism drops again, the servo system drives the packaging cardboard to drop to the height of a package again; and so on, the precise positioning of multi-layer packages in the carton can be achieved.

[0032] Working principle of the present invention: Figure 1 As shown, the feeding belt realizes step-by-step feeding, moves in a controlled manner on the conveyor line in the direction marked by the arrow in the figure, and is fed into the rolling-screen bag-dropping mechanism. The servo motor starts, the rolling screen opens, and the packages fall onto the packaging cardboard. The servo system drives the cardboard to drop to the height of the packages. The feeding belt feeds again in a step-by-step manner and enters the rolling-screen bag-dropping mechanism. The rolling screen opens, and the packages fall onto the cardboard. The servo system drives the cardboard to drop to the height of the packages. By analogy, the precise positioning of multi-layer packages in the carton can be achieved.

[0033] Specific description of the working condition: the package moves forward according to the arrow in the figure. At this time, the roller 20 is in a closed state. After the package enters the roller-type bag-dropping mechanism, the servo motor 6 starts, and the motor sprocket 7 rotates accordingly, driving the motor driven sprocket 9 to rotate through the transmission chain 10. The motor driven sprocket 9 drives the transmission shaft 11, and the driving sprocket 12 on it drives the roller chain 18. The roller 20 on it moves quickly and opens, and the package falls. After the package falls, the servo motor 6 starts to reverse again, the motor sprocket 7 rotates, and the transmission chain 10 drives the motor driven sprocket 9 to rotate. The motor driven sprocket 9 drives the transmission shaft 11, and the driving sprocket 12 on it drives the roller chain 18. The roller 20 on it quickly closes and waits for the next package to enter. The assignment parameters of the electronic control system are set according to the production line capacity efficiency indicators, and the mechanism functions are driven in a reciprocating cycle.

[0034] The present invention is an improvement on the original drop-type packaging device, and adopts a rolling ball structure to realize the control of the opening and closing of the material bag dropping port of the bag dropping mechanism, so as to achieve the purpose of multi-layer positioning, uniform bag dropping without impact, stable bag dropping into the packaging box, and smooth reciprocating cycle operation. It is suitable for soft packaging products with multiple layers and multiple packages in one packaging box during carton packaging; it eliminates the shortcomings of the original equipment in that the bag dropping has large vibration and noise, which may scratch the container to be packaged; and it adopts multiple positioning bag dropping to solve the problems of low efficiency of boxing and low production line efficiency. This solution expands the working range and product packaging form of the existing drop-type packaging machine (originally only one layer of products could be packaged, and the products must have hard packaging), effectively improves the stability and efficiency of product packaging, and can achieve a very high standard of product boxing effect, avoiding damage and wear of products during transportation.
