Abstract
Description
Technical Field
[0001] This utility model specifically relates to the field of automatic folding device technology, and more specifically to an automatic folding device for the production and processing of PE clean packaging bags. Background Technology
[0002] In the modern packaging industry, the demand for PE clean packaging bags is increasing, with applications spanning numerous sectors such as food, pharmaceuticals, and electronics, all of which have stringent requirements for packaging hygiene and quality. As the market continues to expand and product quality standards gradually improve, traditional manual folding methods are no longer sufficient to meet the demands for efficient, precise, and hygienic production. This provides a broad context for the research and development and application of automated folding devices.
[0003] Manually folding PE cleanroom packaging bags has several drawbacks. First, production efficiency is extremely low. The limited speed of manual operation makes it impossible to adapt to the fast pace of large-scale industrial production. In today's highly competitive market, low efficiency translates to high costs and low output, severely restricting a company's development and competitiveness. Second, manual folding makes it difficult to ensure consistent folding precision for each bag. Human factors, such as worker fatigue and differences in operator skill, can lead to significant deviations in shape, size, and sealing of the folded bags. This is unacceptable in the demanding cleanroom packaging field, as inaccurate folding can affect the product's protective performance, leading to risks of moisture, contamination, or damage during storage and transportation. Furthermore, manual folding easily introduces human contamination. The operator's hands, breath, and dust, microorganisms, and other impurities from the surrounding environment can adhere to the packaging bags, posing a serious threat to product safety in industries such as food and pharmaceuticals, potentially causing product spoilage, failure, or even endangering consumer health. Utility Model Content
[0004] The purpose of this utility model is to provide an automatic folding device for the production and processing of PE clean packaging bags. By installing a negative pressure suction cup device and a conveying device, and then installing the folding device and the conveying device, the PE clean packaging bags can be automatically folded, thereby solving the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] An automatic folding device for the production and processing of PE clean packaging bags, comprising:
[0007] A negative pressure suction cup device, wherein one end of the negative pressure suction cup device is provided with a conveying device, and the other end of the conveying device is provided with a folding device;
[0008] The negative pressure suction cup device includes a bottom mounting frame, on which a placement plate is provided. The upper surface of the placement plate is symmetrically provided with sliding grooves, and one end is provided with a telescopic cylinder. The other end of the telescopic cylinder is connected to a sliding table, and the sliding table is slidably connected to the placement plate through the sliding grooves.
[0009] As a further technical solution of this utility model, the top of the bottom mounting bracket is fixedly connected to the top box, the inner side of the top box is provided with a telescopic cylinder two, the other end of the telescopic cylinder two is connected to the slide, the two sides of the slide are slidably connected to the top box, and the slide is provided with a cylinder one, the bottom of the cylinder one is provided with multiple negative pressure suction cups.
[0010] As a further technical solution of this utility model, the conveying device includes a fixed frame, a conveyor belt at the upper end of the fixed frame, and a motor at one end, which is connected to the driving rotating shaft through a toothed chain; the other end of the fixed frame is provided with a driven rotating shaft, and both the driven rotating shaft and the driving rotating shaft are located inside the conveyor belt.
[0011] As a further technical solution of this utility model, the folding device includes a base frame, an upper mounting plate at the top of the base frame, a crease groove on the upper surface of the mounting plate, and a fixed connection between the upper end and the mounting frame. Two cylinders are symmetrically arranged inside the mounting frame, and the bottom of the two cylinders is connected to a crease knife, with the crease knife corresponding to the bottom crease groove.
[0012] As a further technical solution of this utility model, the upper end of the base frame is also provided with a second placement plate, a clamping plate is provided between the second placement plate and the mounting plate, a mechanical arm is provided on one side of the clamping plate, and a movable gripper is provided on the mechanical arm.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. In use, the stacked PE clean packaging bags are first placed on the slide table. The slide table is pushed to the bottom of the negative pressure suction cup by the telescopic cylinder one. The cylinder one at the top of the negative pressure suction cup moves the negative pressure suction cup downward to adsorb the PE clean packaging bags. Then, the cylinder one moves the negative pressure suction cup upward, and the slide frame is moved by the telescopic cylinder two to slide to the top of the conveyor belt. The cylinder one then moves the negative pressure suction cup downward, and the negative pressure in the negative pressure suction cup disappears, thus losing its adsorption force on the PE clean packaging bags. The PE clean packaging bags fall freely onto the conveyor belt. The negative pressure suction cup can accurately adsorb specific parts of the PE clean packaging bags, better control the adsorption force, and adsorb only one PE clean packaging bag at a time, thereby ensuring the orderly progress of the folding process and achieving efficient material transportation.
[0015] 2. In this utility model, after the PE clean packaging bag is placed onto the conveyor belt by the negative pressure suction cup, the conveyor belt is driven by the motor at the bottom to rotate the active rotating shaft. The active rotating shaft drives the conveyor belt to move, and the conveyor belt then drives the driven rotating shaft to rotate. During operation, the conveyor belt can maintain a stable speed and uniform conveying force, so that the PE clean packaging bag can smoothly transition from one stage to another, reducing the displacement, deformation or damage of the packaging bag caused by bumps, shaking, etc., and ensuring the continuity of production and the stability of product quality.
[0016] 3. In this utility model, the PE clean packaging bag is conveyed to the mounting plate via a conveyor belt. The cylinder two inside the mounting frame drives the crease knife to move downwards. The downward pressure of the crease knife presses the middle position of the PE clean packaging bag into the crease groove, forming a clear crease on the PE clean packaging bag, which can provide accurate positioning for subsequent folding. Then, the robotic arm is controlled to pick up the PE clean packaging bag with the movable gripper. The robotic arm folds the PE clean packaging bag according to the preset sequence and angle. The robotic arm is usually equipped with a high-precision motion control system, which can accurately control the position and posture of the movable gripper, and has the characteristics of high precision, flexibility and adaptability.

[0029] The negative pressure suction cup device 1 includes a bottom mounting frame 11, on which a placement plate 14 is provided. The upper surface of the placement plate 14 is symmetrically provided with sliding grooves 15, and one end is provided with a telescopic cylinder 12. The other end of the telescopic cylinder 12 is connected to a slide table 13. The slide table 13 is slidably connected to the placement plate 14 through the sliding grooves 15.
[0030] The bottom mounting bracket 11 is fixedly connected to the top box 16 at the top. The top box 16 is provided with a telescopic cylinder 17 at the inside. The other end of the telescopic cylinder 17 is connected to the slide 18. The two sides of the slide 18 are slidably connected to the top box 16. The slide 18 is provided with a cylinder 19. The bottom of the cylinder 19 is provided with multiple negative pressure suction cups 110.
[0031] By adopting the above technical solution, during use, the stacked PE clean packaging bags are first placed on the slide table 13. The slide table 13 is pushed to the bottom of the negative pressure suction cup 110 by the telescopic cylinder 12. The cylinder 19 at the top of the negative pressure suction cup 110 drives the negative pressure suction cup 110 to move downward to adsorb the PE clean packaging bags. Then, the cylinder 19 drives the negative pressure suction cup 110 to move upward, and the slide 18 is slid by the telescopic cylinder 17 to the top of the conveyor belt 26. The cylinder 19 then drives the negative pressure suction cup 110 to move downward, and the negative pressure in the negative pressure suction cup 110 disappears, thus losing its adsorption force on the PE clean packaging bags. The PE clean packaging bags fall freely onto the conveyor belt 26. The negative pressure suction cup 110 can accurately adsorb specific parts of the PE clean packaging bags, better control the adsorption force, and adsorb only one PE clean packaging bag at a time, thereby ensuring the orderly progress of the folding process and achieving efficient material transportation.
[0032] In this embodiment, the conveying device 2 includes a fixed frame 21, a conveyor belt 26 is provided at the upper end of the fixed frame 21, and a motor 22 is provided at one end. The motor 22 is connected to the driving rotating shaft 24 through a toothed chain 23. The other end of the fixed frame 21 is provided with a driven rotating shaft 25. Both the driven rotating shaft 25 and the driving rotating shaft 24 are located inside the conveyor belt 26.
[0033] By adopting the above technical solution, when the PE clean packaging bag is placed onto the conveyor belt 26 by the negative pressure suction cup 110, the conveyor belt 26 drives the active rotating shaft 24 to rotate through the motor 22 at the bottom. The active rotating shaft 24 drives the conveyor belt to move, and the conveyor belt 26 then drives the driven rotating shaft 25 to rotate. During operation, the conveyor belt 26 can maintain a stable speed and uniform conveying force, so that the PE clean packaging bag can smoothly transition from one stage to another, reducing the displacement, deformation or damage of the packaging bag caused by bumps, shaking, etc., and ensuring the continuity of production and the stability of product quality.
[0034] In this embodiment, the folding device 3 includes a base frame 31, an upper mounting plate 32 is provided at the upper end of the base frame 31, a crease groove 36 is provided on the upper surface of the mounting plate 32, and the upper end is fixedly connected to the mounting frame 33. A second cylinder 34 is symmetrically provided on the inner side of the mounting frame 33, and the bottom of the second cylinder 34 is connected to a crease knife 35. The crease knife 35 corresponds to the bottom crease groove 36.

A mechanical arm 38 is provided on one side of the clamping plate 37, and a movable gripper 39 is provided on the mechanical arm 38.
[0036] By adopting the above technical solution, the PE clean packaging bag is transported to the mounting plate 32 via the conveyor belt 26. The cylinder 34 in the mounting frame 33 drives the crease knife 35 to move downward. The downward pressure of the crease knife 35 presses the middle position of the PE clean packaging bag into the crease groove 36, so that a clear crease is formed on the PE clean packaging bag, which can provide accurate positioning for subsequent folding. Then, the robotic arm 38 is controlled to pick up the PE clean packaging bag through the movable gripper 39. The robotic arm 38 folds the PE clean packaging bag according to the preset sequence and angle. The robotic arm 38 is usually equipped with a high-precision motion control system, which can accurately control the position and posture of the movable gripper 39, and has the characteristics of high precision, flexibility and adaptability.
[0037] The working principle of this utility model is as follows: When in use, the stacked PE clean packaging bags are first placed on the slide table 13. The slide table 13 is pushed to the bottom of the negative pressure suction cup 110 by the telescopic cylinder 12. The cylinder 19 at the upper end of the negative pressure suction cup 110 drives the negative pressure suction cup 110 to move downward to adsorb the PE clean packaging bags. Then, the cylinder 19 drives the negative pressure suction cup 110 to move upward. Then, the slide 18 is slid by the telescopic cylinder 17 to the upper end of the conveyor belt 26. The cylinder 19 then drives the negative pressure suction cup 110 to move downward. As a result, the negative pressure in the negative pressure suction cup 110 disappears, thus losing its adsorption force on the PE clean packaging bags. The PE clean packaging bags fall freely onto the conveyor belt 26. The negative pressure suction cup 110 can accurately adsorb specific parts of the PE clean packaging bags, better control the adsorption force, and adsorb only one PE clean packaging bag at a time, thereby ensuring the orderly progress of the folding process and achieving efficient material transportation.
[0038] When the PE clean packaging bag is placed onto the conveyor belt 26 by the negative pressure suction cup 110, the conveyor belt 26 drives the active rotating shaft 24 to rotate through the motor 22 at the bottom. The active rotating shaft 24 drives the conveyor belt to move, and the conveyor belt 26 then drives the driven rotating shaft 25 to rotate. During operation, the conveyor belt 26 can maintain a stable speed and uniform conveying force, so that the PE clean packaging bag can smoothly transition from one stage to another, reducing the displacement, deformation or damage of the packaging bag caused by bumps, shaking, etc., and ensuring the continuity of production and the stability of product quality.
[0039] The PE clean packaging bag is conveyed to the mounting plate 32 via the conveyor belt 26. The cylinder 34 in the mounting frame 33 drives the crease knife 35 to move downward. The downward pressure of the crease knife 35 presses the middle position of the PE clean packaging bag into the crease groove 36, forming a clear crease on the PE clean packaging bag, which can provide accurate positioning for subsequent folding. Then, the robotic arm 38 is controlled to pick up the PE clean packaging bag through the movable gripper 39. The robotic arm 38 folds the PE clean packaging bag according to the preset sequence and angle. The robotic arm 38 is usually equipped with a high-precision motion control system, which can accurately control the position and posture of the movable gripper 39, and has the characteristics of high precision, flexibility and adaptability.
