Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to an automatic bagging machine for disposable bowls or cups. Background Technology

[0002] Disposable bowls and cups are common tableware items in daily life. During packaging, they are usually stacked into multiple strips and then sealed in a bag. Previously, this was done manually, which was inefficient and could contaminate the bowls and cups. Therefore, to improve packaging efficiency and reduce labor costs, fully automatic packaging machines are now commonly used. For example, Chinese patent CN218751559U discloses a fully automatic bag-type disposable cup packaging machine. This machine, through the design of a conveying mechanism, a pushing mechanism, a bag conveying mechanism, and a bagging mechanism, achieves fully automatic packaging of disposable cups, reducing labor costs, improving packaging efficiency, and realizing aseptic packaging.

[0003] A sealing strip is a structure that uses concave and convex ribs to seal the packaging. Packaging bags with sealing strips can be repeatedly opened and resealed, reducing the problem of disposable bowls or cups becoming contaminated after being opened and unable to be resealed during daily use. The packaging machine mentioned above can only be used for packaging bags without sealing strips. For packaging bags with sealing strips, it is still necessary to manually open the strip and manually reseal it after packaging. This method is undoubtedly inefficient and has high labor costs. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides an automatic bagging machine for disposable bowls or cups. This bagging machine is designed for packaging bags with sealing strips and can automatically open and close the sealing strips during the packaging process of disposable bowls or cups, thereby achieving fully automated packaging of disposable bowls or cups, reducing labor costs and improving packaging efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An automatic bagging machine for disposable bowls or cups is provided, including a frame, on which a conveying mechanism, a bag-opening mechanism, a bag-filling mechanism, and a bag-sealing mechanism are arranged.

[0006] The conveying mechanism is used to transport the bag body, and the bag opening mechanism, bag filling mechanism and bag sealing mechanism are arranged sequentially along the conveying direction of the conveying mechanism;

[0007] The bag opening mechanism includes a first suction nozzle, a second suction nozzle, a first bag support clamp, and a second bag support clamp. The first and second suction nozzles are vertically arranged and can move up and down relative to each other. By moving up and down relative to each other, they can respectively adhere to the upper and lower sides of the sealing part of the bag body and pre-open the sealing part. The first and second bag support clamps are vertically arranged and can move up and down relative to each other, move forward and backward together, and perform clamping actions. By moving forward and backward together, they can be inserted into the pre-opened sealing part of the bag body. By clamping actions, they can respectively clamp the upper and lower sides of the sealing part. By moving up and down relative to each other, they can open the sealing strip of the sealing part.

[0008] The bagging mechanism is used to open the bag and push the disposable bowl or cup into the bag;

By moving forward and backward together, they can move to the left and right sides of the bag's sealing portion. By clamping, they can clamp the left and right sides of the sealing portion. By moving left and right in opposite directions, they can flatten the sealing portion. The pressing component and the pressure plate are arranged vertically and can move up and down in opposite directions. By moving up and down in opposite directions, they press against the upper and lower sides of the sealing portion respectively. The pressing component can also move left and right, and by moving left and right, it can press the sealing strip of the sealing portion.

[0010] As a further improvement of this utility model, the conveying mechanism includes a first conveyor belt, a second conveyor belt, a third conveyor belt, a fourth conveyor belt, and a first suction cup manipulator, a second suction cup manipulator, and a third suction cup manipulator; the first, second, and third conveyor belts are arranged in a straight line sequentially, and the fourth conveyor belt is located at the end of the third conveyor belt and is arranged in an L-shape with the third conveyor belt; the bag is conveyed sequentially on the first, second, third, and fourth conveyor belts; the first suction cup manipulator is located between the first and second conveyor belts and is used to suction and move the bag on the first conveyor belt to the second conveyor belt; the second suction cup manipulator is located between the second and third conveyor belts and is used to suction and move the bag on the second conveyor belt to the third conveyor belt; the third suction cup manipulator is located between the third and fourth conveyor belts and is used to suction and move the bag on the third conveyor belt to the fourth conveyor belt.

[0011] As a further improvement of this utility model, the bag opening mechanism is located between the first conveyor belt and the second conveyor belt. The second conveyor belt can reverse to transport the bag body to the bag opening mechanism for opening. After opening, the bag body is transferred out of the bag opening mechanism via the second conveyor belt and transported to the third conveyor belt.

[0012] As a further improvement of this utility model, the bagging mechanism and the sealing mechanism are arranged sequentially along the transmission direction of the fourth conveyor belt.

[0013] As a further improvement of this utility model, both the first bag support clamp and the second bag support clamp include an insert plate and a movable plate. The movable plate is hinged to the insert plate and is driven by a cylinder. The opening and closing of the movable plate and the insert plate is realized by the extension and retraction of the cylinder. The first bag support clamp and the second bag support clamp can close their insert plates together by moving them up and down. After closing, the ends of the two insert plates form triangular tips that can be inserted into the pre-opened sealing part of the bag.

[0014] As a further improvement of this utility model, the first suction nozzle and the second suction nozzle are driven by a cylinder, which drives the first suction nozzle and the second suction nozzle to move up and down; the first bag support clamp and the second bag support clamp are driven by a cylinder, which drives the first bag support clamp and the second bag support clamp to move up and down and forward and backward.

[0018] The beneficial effects of this utility model are as follows: For packaging bags with sealing strips, the bagging machine is equipped with a bag opening mechanism and a bag sealing mechanism. Through the above structure, the sealing strip can be automatically opened and pressed during the packaging process of disposable bowls or cups, realizing fully automated packaging of disposable bowls or cups, thereby significantly reducing labor costs and significantly improving production efficiency, making it suitable for large-scale industrial production needs. The bag opening mechanism uses a first suction nozzle and a second suction nozzle that move vertically in opposite directions. It first suctions and pre-opens the sealed part of the bag, and then inserts, clamps, and opens the sealing strip through a bag support clamp. This ensures that the opening of the bag is stable and the position is accurate, avoiding damage to the bag or failure to open the bag. The bag sealing mechanism flattens the sealed part by pulling the bag clamp in opposite directions, and then cooperates with the vertical pressing of the pressing component and the pressure plate, as well as the horizontal movement of the pressing component. First flattening and then horizontally pressing ensures that the sealing strip is accurately aligned and that the sealing strip is pressed tightly and not easily loosened, thereby improving packaging quality.

Detailed Implementation

[0025] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0026] like Figure 1As shown, an automatic bagging machine for disposable bowls or cups is used for packaging bags with sealing strips, enabling fully automated packaging of disposable bowls or cups. The bagging machine includes a frame, on which are mounted a conveying mechanism 1, a bag-opening mechanism 2, a marking mechanism 3, a bag-filling mechanism 4, a bag-sealing mechanism 5, and a heat-sealing mechanism 6. The conveying mechanism 1 is used to transport the bag body. The bag-opening mechanism 2, the marking mechanism 3, the bag-filling mechanism 4, the bag-sealing mechanism 5, and the heat-sealing mechanism 6 are arranged sequentially along the conveying direction of the conveying mechanism 1.

[0027] The conveying mechanism 1 includes a first conveyor belt 11, a second conveyor belt 12, a third conveyor belt 13, and a fourth conveyor belt 14 driven by a motor, and a first suction cup robot 15, a second suction cup robot 16, and a third suction cup robot 17 driven by a motor and a cylinder. The first, second, and third conveyor belts 11, 12, and 13 are arranged in a straight line sequentially. The fourth conveyor belt 14 is located at the end of the third conveyor belt 13 and forms an L-shape with it. Bags are conveyed sequentially on the first, second, third, and fourth conveyor belts 11 and 14. During conveying, the sealed portion of the bag remains in one direction, always facing the front end of the first conveyor belt 11, with the bag moving from the front end to the rear end of the first conveyor belt 11. The first suction cup robot 15 is located between the first and second conveyor belts 11 and is used to suction and move the bag from the first conveyor belt 11 onto the second conveyor belt 12. The second suction cup robot 16 is located between the second conveyor belt 12 and the third conveyor belt 13, and is used to suction and move the bag on the second conveyor belt 12 to the third conveyor belt 13. The third suction cup robot 17 is located between the third conveyor belt 13 and the fourth conveyor belt 14, and is used to suction and move the bag on the third conveyor belt 13 to the fourth conveyor belt 14. The bag opening mechanism 2 is located between the first conveyor belt 11 and the second conveyor belt 12. The second conveyor belt 12 can reverse to transport the bag to the bag opening mechanism 2 for opening. After opening, the bag is transferred forward through the second conveyor belt 12 out of the bag opening mechanism 2 and transported towards the third conveyor belt 13. The marking mechanism 3, the bag filling mechanism 4, the bag sealing mechanism 5, and the heat sealing mechanism 6 are arranged sequentially along the transmission direction of the fourth conveyor belt 14.

[0028] like Figure 2 , 3As shown, the bag opening mechanism 2 includes a first suction nozzle 21, a second suction nozzle 22, a first bag support clamp 23, and a second bag support clamp 24. The first suction nozzle 21 and the second suction nozzle 22 are vertically arranged and connected to a cylinder, which drives the first suction nozzle 21 and the second suction nozzle 22 to move vertically. This vertical movement allows them to adhere to the upper and lower sides of the bag's sealing portion, pre-opening the seal. The first bag support clamp 23 and the second bag support clamp 24 are also vertically arranged and connected to a cylinder, which drives them to move vertically, forward and backward, and perform clamping actions. This forward and backward movement allows them to be inserted into the pre-opened sealing portion of the bag. The clamping action grips the upper and lower sides of the sealing portion, and the vertical movement opens the sealing strip.

[0029] The specific structures of the first bag support clamp 23 and the second bag support clamp 24 are as follows: Both the first bag support clamp 23 and the second bag support clamp 24 include an insert plate 25 and a movable plate 26. The movable plate 26 is hinged to the insert plate 25, and the movable plate 26 is connected to a cylinder. The opening and closing of the movable plate 26 and the insert plate 25 is achieved by the extension and retraction of the cylinder to realize the clamping action. The first bag support clamp 23 and the second bag support clamp 24 can close their insert plates 25 together by moving up and down. After closing, the ends of the two insert plates 25 form triangular tips that can be inserted into the pre-opened sealing part of the bag. Through the triangular tips, the first bag support clamp 23 and the second bag support clamp 24 can be accurately inserted into the pre-opened sealing part, thereby reducing the probability of bag opening failure.

[0030] like Figure 4 , 5 As shown, the bag sealing mechanism 5 includes a first bag clamp 51, a second bag clamp 52, a pressing component 53, and a pressure plate 54. The first bag clamp 51 and the second bag clamp 52 are arranged horizontally and are connected to a cylinder and a motor. The cylinder drives the first bag clamp 51 and the second bag clamp 52 to move horizontally in opposite directions and forward and backward together. The motor drives the first bag clamp 51 and the second bag clamp 52 to perform clamping actions. The simultaneous forward and backward movement of the first bag clamp 51 and the second bag clamp 52 moves them to the left and right sides of the bag's sealing portion, clamping the left and right sides of the sealing portion. The horizontal movement in opposite directions flattens the sealing portion. The pressing component 53 and the pressure plate 54 are arranged vertically and are connected to a cylinder and a motor. The cylinder drives the pressing component 53 and the pressure plate 54 to move vertically in opposite directions, and the motor drives the pressing component 53 to move horizontally. The pressing member 53 and the pressure plate 54 can be pressed together on the upper and lower sides of the sealing part by moving up and down. The pressing member 53 can move left and right on the upper side of the sealing strip. During the left and right movement, it cooperates with the pressure plate 54 to apply pressure to the sealing strip, so that the sealing strip is pressed together.

[0031] The marking mechanism 3 is used to laser mark the bag. The bagging mechanism 4 is used to open the bag and push the disposable bowl or cup into the bag. The heat sealing mechanism 6 is used to heat-seal the bag at the end of the packaging process. The above mechanisms are commonly used in existing disposable bowl or cup packaging devices, and therefore will not be described in detail.

[0032] The workflow of the bagging machine described above is as follows:

[0033] 1. The bag enters the first conveyor belt 11, which carries the bag towards the second conveyor belt 12. When the bag reaches the end of the first conveyor belt 11, the first suction cup robot arm 15 picks up the bag from the first conveyor belt 11 and moves it onto the second conveyor belt 12.

[0034] Second, the second conveyor belt 12 reverses, allowing the bag to be conveyed to the bag opening mechanism 2. The first suction nozzle 21 and the second suction nozzle 22 of the bag opening mechanism 2 move together vertically, respectively adsorbing onto the upper and lower sides of the sealed portion of the bag, and then move apart vertically, thereby pre-opening the sealed portion. Then, the first bag support clamp 23 and the second bag support clamp 24 move together vertically and forward, inserting into the pre-opened sealed portion of the bag. The movable plate 26 of the first bag support clamp 23 and the second bag support clamp 24 actuates, causing the first bag support clamp 23 and the second bag support clamp 24 to clamp onto the upper and lower sides of the sealed portion, respectively. Then, the first bag support clamp 23 and the second bag support clamp 24 move backward and move apart vertically, opening the sealing strip of the sealed portion.

[0035] Third, after the bag's sealing strip is opened, the second conveyor belt 12 rotates forward, causing the bag to leave the bag opening mechanism 2 and move to the end of the second conveyor belt 12. Then, the second suction cup robot 16 picks up the bag on the second conveyor belt 12 and moves it to the third conveyor belt 13. When the bag moves to the end of the third conveyor belt 13, the third suction cup robot 17 picks up the bag on the third conveyor belt 13 and moves it to the fourth conveyor belt 14.

[0036] Fourth, the bag is driven into the marking mechanism 3 by the fourth conveyor belt 14, and laser marking is performed on the bag by the marking mechanism 3.

[0037] 5. After the bag is marked, it is driven by the fourth conveyor belt 14 into the bagging mechanism 4. The bagging mechanism 4 opens the bag and pushes the disposable bowl or cup into the bag to complete the bagging operation.

[0038] VI. After bagging, the bag body is driven into the sealing mechanism 5 by the fourth conveyor belt 14. The first bag clamp 51 and the second bag clamp 52 of the sealing mechanism 5 move forward to the left and right sides of the bag body and clamp the left and right sides of the bag body. Then, the first bag clamp 51 and the second bag clamp 52 move apart to the left and right to flatten the sealing part of the bag body. The pressing component 53 and the pressure plate 54 move together to press the pressing component 53 and the pressure plate 54 onto the upper and lower sides of the sealing part, respectively. The pressing component 53 moves horizontally left and right on the upper side of the sealing strip. During the horizontal movement, it cooperates with the pressure plate 54 to apply pressure to the sealing strip, so that the sealing strip is pressed together, thereby realizing the sealing operation of the sealing strip.

[0039] 7. After the sealing strip is completed, the bag is carried by the fourth conveyor belt 14 into the heat sealing mechanism 6. The heat sealing mechanism 6 heat-seales the sealing part of the bag, thus completing the entire packaging process for the disposable bowl or cup.

[0040] The above-described embodiments are merely illustrative of this utility model. Any equivalent embodiments made by those skilled in the art without departing from the technical features disclosed in this utility model, and without departing from the technical features of this utility model, shall still fall within the scope of the technical features of this utility model.
