Description

Technical Field

[0001] The utility model belongs to the technical field of packaging machinery, and in particular relates to a packaging machine with a soft-bag multi-layer positioning rolling curtain bag dropping mechanism. Background Art

[0002] Currently, competition in the packaging sector is becoming increasingly fierce in both domestic and international packaging industries, with rapid product updates and iterations. This requires packaging equipment to have a high price-performance ratio and attractive packaging appearance. For flexible packaging such as wet wipes and tissue paper, they need to be packed into cartons according to category and quantity. Common packaging equipment on the market today includes robotic packaging equipment, but it is relatively expensive. Traditional carton packing machines are less expensive, but they require a carton opener to pre-make cartons and use tape to seal the cartons after packing, which is inconsistent with current environmental trends. Traditional drop-type packaging machines are simple to operate and inexpensive, but are only suitable for containers with solid shapes such as cans and bottles, and are not suitable for flexible packaging products. Therefore, it is necessary to design a drop-down packaging mechanism for a one-piece cardboard machine that can be used for dry / wet wipes, tissue paper, etc., to achieve high packaging product conversion efficiency, smooth carton drop, and smooth reciprocating cycle operation. Utility Model Content

The utility model improves the bag dropping structure on the basis of the existing drop-type packaging, and can use the box-packing and dropping bag mechanism of the soft-package product to achieve the purpose of multi-layer positioning, uniform bag dropping without impact, stable bag dropping, high packaging product conversion efficiency, and smooth reciprocating cycle operation.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by this utility model is:

[0005] A packaging machine with a soft-bag multi-layer positioning roller curtain bag dropping mechanism includes a feed belt, the output end of which is connected to a roller curtain bag dropping mechanism. The roller curtain bag dropping mechanism uses a roller curtain ball structure to open and close the material dropping port. A stepping drop mechanism for supporting the packaging cardboard is provided directly below the material dropping port of the roller curtain bag dropping mechanism.

[0006] To further define the above scheme, the rolling curtain type bag dropping mechanism includes a bag dropping frame, which is open on the front side facing the output end of the feed belt and is used for feeding. A rolling curtain ball assembly is provided on the material bag dropping opening at the bottom of the bag dropping frame, and a rolling curtain ball drive assembly for driving the rolling curtain ball assembly to move is provided on the bag dropping frame. The rolling curtain ball drive assembly drives the rolling curtain ball assembly to move to open the material bag dropping opening for bag dropping or to close the material bag dropping opening.

[0007] As a further limitation of the above solution, the package dropping frame includes two left and right square side panels, and the two square side panels are connected by support columns and connecting support plates.

[0008] A further limitation of the above scheme is that the rolling shutter ball assembly includes a transmission shaft, a driving sprocket, a driven sprocket shaft, a driven sprocket, a roller chain and a rolling shutter roller, and a transmission shaft is supported by a diamond-shaped seat bearing at one corner of the two square side panels, and driving sprockets are provided at both ends of the transmission shaft and on the inner side of the square side panels, and the driven sprocket shaft is fixed at the other three corners on the inner side of the two square side panels, and the driven sprocket shaft supports a driven sprocket through a deep groove ball bearing, and a roller chain is wound around the driving sprocket and the driven sprocket on the inner side of each square side panel, and the rolling shutter roller is provided with multiple rollers arranged in a row, and the two ends of the rolling shutter roller are respectively connected to the roller chains on both sides; a guide rail for guiding the roller chain is provided on the upper inner side of the two square side panels, and the roller chain is in the guide rail.

[0010] As a further limitation of the above solution, a material baffle is provided at the lower rear portion of the bag dropping frame.

[0011] To further limit the above scheme, the step-by-step falling mechanism includes a vertically erected screw rod, which is connected to the servo system, and a screw nut is screwed on the screw rod, and a packaging cardboard support frame is fixedly connected to the screw nut, and the packaging cardboard support frame is facing the material dropping port of the rolling curtain type dropping mechanism.

[0012] The advantages of this utility model compared with the prior art are:

[0013] 1. This solution improves upon the existing drop-type packaging device, employing a rolling ball structure to control the opening and closing of the bag-dropping mechanism's material drop-off opening. This achieves multi-layer positioning, uniform bag drop without impact, smooth box drop, and smooth reciprocating operation. It is suitable for flexible packaging products with multiple layers and multiple packages per layer within a carton during carton packaging.

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

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

[0022] In this embodiment, a step-by-step feeding mechanism (for single-layer packages) is used. The lower packaging cardboard is accurately positioned by a servo system. The curtain opens, allowing the package to fall onto the cardboard. The servo system then lowers the cardboard by the same height as the package. The step-by-step feeding mechanism then re-enters the curtain-type drop mechanism. The curtain opens, allowing the package to fall onto the cardboard. The servo system then lowers the cardboard by the same height as the package. This process continues, achieving precise positioning of multi-layer packages within the carton. This curtain-type drop mechanism replaces the sliding friction of traditional slide-type drop mechanisms with rolling friction, which helps maintain the stability of lightweight flexible packages during the drop process, thereby improving packaging efficiency and equipment operational stability.

[0023] In a specific embodiment: 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 bag dropping or to close the material bag dropping opening.

[0024] Specifically, the package dropping frame 3 includes two left and right square side panels 4 , and the two square side panels 4 are connected by support columns 5 and connecting support plates 16 .

[0025] For details, see Figure 1 and 2As 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 plates 4. Driving sprockets 12 are provided at both ends of the transmission shaft 11 and on the inner side of the square side plates 4. The driven sprocket shaft 13 is fixed at the other three corners on the inner side of the two square side plates 4. The driven sprocket shaft 13 supports the driven sprocket 15 through deep groove ball bearings 14. The driving sprocket 12 and the driven sprocket 15 on the inner side of each of the square side plates 4 are wound around the roller chain 18. The rolling curtain roller 20 is provided in plurality 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 plates 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 roller roller 20 connected thereto can be flat, forming a good opening and closing control of the material drop-off port.

[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, and 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 embodiment: 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 nut 23 is screwed on the screw rod 22, and a packaging cardboard support frame 24 is fixedly connected to the screw nut 23. The packaging cardboard support frame 24 is facing the material dropping port of the rolling curtain type dropping mechanism 2.

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

[0032] Working principle of this utility model: 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 curtain bag dropping mechanism. The servo motor starts, the rolling curtain opens, and the package falls onto the packaging cardboard. The servo system drives the cardboard to drop to the height of the package; the material is fed again in a step-by-step manner and enters the rolling curtain bag dropping mechanism. The rolling curtain opens and the package falls onto the cardboard. The servo system drives the cardboard to drop to the height of the package; and so on, 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 shutter 20 is in the closed state. After the package enters the roller shutter bag drop mechanism, the servo motor 6 starts, and the motor sprocket 7 rotates accordingly. The transmission chain 10 drives the motor driven sprocket 9 to rotate. The motor driven sprocket 9 drives the transmission shaft 11. The driving sprocket 12 on it drives the roller chain 18. The roller shutter 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. The driving sprocket 12 on it drives the roller chain 18. The roller shutter 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] This utility model is an improvement on the original drop-type packaging device. It adopts a roller ball structure to realize the control of the opening and closing of the material 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, and smooth reciprocating cycle operation. It is suitable for soft packaging products with multiple layers and multiple packages in one box during carton packaging. It eliminates the shortcomings of the original equipment of large vibration and noise when dropping bags, which may scratch the container to be packaged. It also adopts multiple positioning and bag dropping to solve the problems of low efficiency of bag dropping and low efficiency of production line. This solution expands the working range and product packaging form of the existing drop-type packaging machine (originally it could only package one layer of products 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 packaging effect, avoiding damage and wear of products during transportation.
