Description

Technical fields:

[0001] This invention relates to the field of packaging, specifically to a packaging machine. Background technology:

[0002] Currently, clothing packaging machines on the market are slow, have low automation, and cannot package many types of clothing, such as surgical gowns. In particular, when the materials on both sides of the packaging bag are different, manual packaging is the only option. Furthermore, the bag clamping and opening structures commonly found on clothing packaging machines are complex, take up a lot of space, and are prone to wear and tear, so they are rarely used in the hygiene products, food, and medical industries. Furthermore, for the medical packaging and apparel packaging industries, there is still a lack of such packaging opening structures and packaging bag heat sealing mechanisms. While reasonable heat sealing temperatures and pressures can be achieved by adjusting the temperature of the heating element and the cylinder pressure or the torque of the servo motor, the width of the heat seal cannot be adjusted using the existing structure. When changing packaging bags, the width of the bag that can be filled is limited due to machine space constraints, which cannot meet the customer's change-of-type requirements. To ensure the flatness of the seal, the processing and assembly precision of mechanical parts are required to be very high. Moreover, the bag-opening mechanism of packaging machines often uses a cylinder connected to a connecting rod to push open the bag-opening plate, or uses two cylinders moving relative to each other. These two types of bag-opening structures require other structures to be used in advance to put the bag on the bag-opening plate before opening the bag, which is complex, inefficient, and not very stable.

[0003] For example, application number CN201611136007.1 discloses a garment folding and packaging machine, including a frame on which a sleeve folding and ironing device, a garment folding device, and a garment packaging device are sequentially arranged along the garment feeding direction. The sleeve folding and ironing device includes a garment conveying mechanism, a sleeve folding mechanism cooperating with the garment conveying mechanism, and an ironing mechanism transitionally connected to the garment conveying mechanism. The garment folding device includes a third conveying mechanism, a fourth conveying mechanism, and a lifting mechanism transitionally connected to the garment output conveyor belt. The garment packaging device includes a packaging worktable, a packaging bag storage box, a sixth drive mechanism for absorbing packaging bags and placing them flat on the packaging worktable, a fifth drive mechanism for opening the packaging bag opening, and a receiving box connected to the packaging worktable. This folding and packaging machine can automatically complete the tasks of folding, ironing, and packaging garments; it can realize the folding function of products. However, this technology cannot achieve packaging when the two sides of the packaging bag are made of different materials. Summary of the Invention:

[0004] To address the shortcomings of existing technologies, this invention provides a packaging machine that can package surgical gowns.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

The feeding section is located on one side of the lifting and compression section. The bag-supporting section opens the bags through the bag-opening section. The pushing section pushes the product into the opened bag. After being bagged, the product is rotated to the heat-sealing section for heat sealing. The product is then rotated by the turntable section to the pushing section, which pushes the finished product out of the machine onto the discharge conveyor line. The bag storage section stacks the bags and places them on the conveyor line, where the bag-retrieving section retrieves them. The bag-retrieving section places the retrieved bags on a pallet in the bag-forming section for bag positioning and shaping. The bag opening section includes two gripper cylinders, an upper bag opening cylinder, and a lower bag opening cylinder. The upper and lower bag opening cylinders are each equipped with several suction cups. A push plate cylinder is provided on the outside of the gripper cylinder, and a compression device is provided on the inside. The heat sealing section includes an upper heat sealing plate and a lower heat sealing plate arranged opposite each other. The upper heat sealing plate and / or the lower heat sealing plate are equipped with a balance adjustment device, which includes a balance adjustment screw for adjusting the seal in the Y-axis direction. The bag supporting section includes a bag supporting cylinder, a linkage mechanism, a rotating shaft, and a bag supporting plate. The bag supporting cylinder is connected to the linkage mechanism, the linkage mechanism is connected to the rotating shaft, and the rotating shaft is connected to the bag supporting plate.

[0007] As a further embodiment of the present invention, a limit adjustment screw is provided between the gripper cylinder and the push plate cylinder to limit the return stroke of the gripper cylinder, and the upper bag opening cylinder and the lower bag opening cylinder are respectively provided with two suction cups.

[0008] As a further embodiment of the present invention, the compression device is a compression spring, and the lower end of the suction cup is provided with a position adjustment device.

[0009] As a further embodiment of the present invention, the bag-supporting cylinder is connected to a linkage mechanism via a slider, and a fixed plate is connected to the lower end of the bag-supporting cylinder. A sliding groove is provided on the fixed plate, and the slider is connected to the sliding groove.

[0010] As a further embodiment of the present invention, the bag support plate includes two bag support units, each of which is connected to a rotating shaft. The opposite sides of the two bag support units are arc-shaped, and the rotating shaft is fixedly connected to the bag support plate.

[0011] As a further embodiment of the present invention, the heat sealing part further includes a sealing position adjusting plate for adjusting the sealing position in the X-axis direction, and the lower heat sealing plate is provided with a balance adjusting device. The lower heat sealing plate is fixed to the lower crossbar by a rotating pin.

[0012] As a further embodiment of the present invention, a lower heat insulation block is provided between the rotating pin and the lower crossbar, a fixed bracket is connected to the sealing position adjustment plate, and sealing position adjustment plates are respectively provided at the upper end of the upper heat sealing plate and the lower end of the lower heat sealing plate.

[0013] As a further embodiment of the present invention, the sealing position adjustment plate is provided with a plurality of adjustment screw holes at both ends, the fixed bracket is provided with a plurality of fixed screw holes corresponding to the adjustment screw holes at both ends, the upper heat sealing plate is provided with an upper heat insulation block, the upper end of the upper heat sealing plate is provided with an upper heat sealing cylinder, and the lower end of the lower heat sealing plate is provided with a lower heat sealing cylinder.

[0014] The present invention has the following beneficial effects:

[0015] The packaging machine of this invention can be adapted to different sizes of clothing by adjusting the bag opening section and the heat sealing section. The bag opening section of this invention uses two gripper cylinders, an upper bag opening cylinder, and a lower bag opening cylinder to be suitable for bags of different materials. At the same time, the use of two gripper cylinders, an upper bag opening cylinder, and a lower bag opening cylinder can facilitate bag opening while ensuring stability and portability. The technology of this invention can fill the gap in the market for high-speed packaging machines. By feeding and stretching the bag in different directions and operating by rotation, high-speed packaging can be achieved, resulting in higher efficiency and a smaller footprint, making it particularly suitable for packaging clothing and other items.

[0016] This invention utilizes a clamping bag opening structure to allow the bag to be clamped from an empty state until heat sealing, preventing the bag from becoming loose and ensuring a smooth seal. This significantly improves the sealing success rate, ensuring the seal remains level and taut throughout the sealing process, preventing air leakage and uneven sealing. This greatly enhances product aesthetics and the overall pass rate. It is particularly useful in packaging surgical gowns and other high-sealing materials, and the balance adjustment device allows for precise heat sealing. The sealing adjustment is achieved along the Y-axis of the plate; the sealing position is adjusted along the X-axis via the sealing position adjustment plate, enabling packaging of different products and facilitating adjustments to sealing length, width, etc.; and a rotating bag opening method via a linkage mechanism results in a simple structure with minimal space occupation. This structural design facilitates the insertion of the packaged items into the bag, and the rotating method improves the flatness of the packaged items during the bag insertion process, while ensuring that the bag remains flat throughout the process, preventing wrinkles and improving stability in subsequent operations.

[0017] To more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Attached image description:

[0019] Figure 2 This is a schematic diagram of the bag opening section in this invention.

[0020] Figure 3 , Figure 4 These are schematic diagrams showing the closed and open states of the bag support portion in this invention.

[0021] Figure 5 This is a schematic diagram of the heat sealing mechanism in this invention. Detailed implementation method:

[0022] The present invention will now be further described in conjunction with the accompanying drawings and relevant knowledge, and will be described clearly and completely. Obviously, the described applications are only some embodiments of the present invention, and not all embodiments.

[0023] See Figures 1-5 As shown, a packaging machine includes a feeding section, a lifting and compression section, a pushing section, a bag-supporting section, a bag-opening section, a turntable section, a heat-sealing section, a discharge pushing section, a discharge conveyor line, a bag-forming section, a bag-retrieving section, and a bag storage section. The feeding section is located on one side of the lifting and compression section. The bag-supporting section opens the bag through the bag-opening section. The pushing section pushes the product into the opened bag. After being bagged, the product is rotated to the heat-sealing section for heat sealing. The product is then rotated by the turntable section to the pushing section, which pushes the finished product out of the machine onto the discharge conveyor line. The bag storage section stacks the bags and places them on the conveyor line, where the bag-retrieving section retrieves the bags. The bag-retrieving section places the retrieved bags on a pallet in the bag-forming section for bag positioning.

[0024] The specific working method is as follows: The product is placed into the feeding section 1, and the servo motor drives the chain and lever to transport the product. When the product reaches the lifting and compression section 2, the lifting and compression section 2 lifts and compresses the product to a certain width. The bag-supporting section 4 opens the bag opened by the bag-opening section 5, and the pushing section 3 pushes the product into the opened bag. After the product is put into the bag, it is clamped by the claws on the turntable section 6 and rotated to the heat-sealing section 8 for heat sealing. After heat sealing, the product is rotated by the turntable section 6 to the discharge pushing section 9. The discharge pushing section 9 pushes the finished product out of the equipment to the discharge conveyor line 10 and is transported out. The bags in the bag storage section 13 are stacked by hand and placed on the conveyor line. The bag-retrieving section 12 retrieves the bags. After a stack of bags is retrieved, the bag is transported to the bag-retrieving position by the conveyor line. The bag-retrieving section 12 retrieves the bags and places them on the tray of the bag-forming section 11. The bags are shaped to ensure that the position of each bag is the same. Then, they are clamped by the claws on the turntable section 6 and rotated to reach the subsequent workstations.

[0025] In this invention, reference is made to Figure 2The bag opening section shown includes two gripper cylinders 131, an upper bag opening cylinder 14, and a lower bag opening cylinder 15. The upper and lower bag opening cylinders 14 and 15 are each equipped with several suction cups 16 for adsorbing the front and back of the bag. A pusher cylinder 18 is located outside the gripper cylinder 131, and a compression device 19 is located inside. Specifically, the grippers of the gripper cylinders grasp the two sides of the bag, and the pusher cylinder 18 compresses the compression device 19 and suction cups 16 to open the bag. This ensures that the bag opening remains open throughout the packaging process. The bag is in a taut state; after opening, it enters the product loading process; after the product is fed, the suction cup closes, the push plate cylinder returns, and the bag closes. A limit adjustment screw is provided between the gripper cylinder 131 and the push plate cylinder 18 to limit the return of the gripper cylinder. This ensures that the position where the gripper cylinder stops returning is the same as its starting position, guaranteeing the flatness of the bag closure. The upper and lower opening cylinders each have two suction cups, and the compression device is a compression spring to compress and extend the gripper cylinder. A position adjustment device 17 is provided at the lower end of the suction cup 16, allowing adjustment of the position between the two suction cups to accommodate bags of different sizes.

[0026] In a further optimized configuration, when the gripper cylinder 131 rotates to clamp the bag and moves it to the opening position, the upper and lower opening cylinders drive the upper and lower suction cups 16 to close, and the vacuum generator sucks up the bag. The left and right push plate cylinders 18 extend, compress the compression spring, and drive the left and right gripper cylinders 131 to close. At the same time, the upper opening cylinder 14 and the lower opening cylinder 15 drive the suction cups 16 to suck up both sides of the bag and open it. After the bag is opened, the front bag-supporting mechanism expands the bag, allowing the product to be pushed into the bag. After the product is fed, the suction cups close, the push plate cylinders return, and the bag closes. The limit adjustment screw ensures that the position where the gripper cylinders stop returning is the same as the starting position, which can ensure the flatness of the bag closure.

[0027] In this invention, reference is made to Figure 3 and Figure 4 As shown, the bag-supporting part includes a bag-supporting cylinder 21, a connecting rod mechanism 22, a rotating shaft 23, and a bag-supporting plate 24. The bag-supporting cylinder 21 is connected to the connecting rod mechanism 22, the connecting rod mechanism 22 is connected to the rotating shaft 23, and the rotating shaft 23 is connected to the bag-supporting plate 24. The bag-supporting cylinder 21 pushes the connecting rod mechanism 22 through the cylinder, the connecting rod mechanism 22 pushes the rotating shaft 23, and the rotating shaft 23 drives the bag-supporting plate 24 to open and close. Figures 3 to 4 In this state, the bag is opened by the bag support plate 24.

[0028] The bag-supporting cylinder 21 is connected to the linkage mechanism 22 via the slider 25. More preferably, a fixed plate 26 is connected to the lower end of the bag-supporting cylinder 21, and a sliding groove 27 is provided on the fixed plate 26. The slider 25 is connected to the sliding groove 27. The specific working method is as follows: the bag-supporting cylinder 21 pushes the slider 25, and the slider 25 further pushes the linkage mechanism 22.

[0029] In this invention, the bag support plate includes two bag support units, each connected to a rotating shaft. More preferably, the opposite sides of the two bag support units are arc-shaped, which makes the opening and closing process smoother. The rotating shaft is fixedly connected to the bag support plate, which ensures that the bag is more stable during the bag support process and will not affect the bag during the product insertion process. It can also ensure that the product is as flat as possible after being pushed in, so as not to affect the subsequent packaging process.

[0030] Further optimization, referring to Figure 3 As shown, while waiting for the bag to arrive, the bag-supporting plate 24 is in a closed state. When the bag is delivered to the position of the cylinder bag-supporting mechanism, the upper and lower bag-opening mechanisms open the bag. Under the action of the bag-supporting cylinder 21, the cylinder bag-supporting mechanism acts on the connecting rod mechanism 22 to drive the rotating shaft 23 to rotate, causing the bag-supporting plate 24 connected to the rotating shaft 23 to open, thereby opening the bag and allowing the product to be smoothly pushed into the bag. The present invention has a simple structure, ingenious design, and occupies little space; the bag-filling and bag-opening are integrated, and the rotary bag-opening method can save more time.

[0031] In this invention, reference is made to Figure 5 As shown, the heat sealing section includes an upper heat sealing plate 30 and a lower heat sealing plate 31 arranged opposite to each other. The upper heat sealing plate 30 and / or the lower heat sealing plate 31 are provided with a balance adjustment device, which includes a balance adjustment screw 35 for adjusting the sealing in the Y-axis direction. Specifically, the height is adjusted by rotating the screw thread to achieve the rotation depth.

[0032] The heat sealing section also includes a sealing position adjusting plate for adjusting the sealing position in the X-axis direction, which is used for horizontal adjustment.

[0033] In this invention, preferably, the lower heat-sealing plate 31 is provided with a balance adjustment device, and the lower heat-sealing plate is fixed to the lower crossbar 38 by a rotating pin 36, as shown in the reference. Figure 5 As shown, the balance adjustment device includes at least one balance adjustment screw 35. The height is adjusted by rotating the balance adjustment screw 35. For example, the height can be adjusted by rotating the screw to the depth of the lower crossbar 38. To better fix the adjusted position, a fixing screw can be added. It should be noted that the balance adjustment device can be set on the lower heat sealing plate 31, or on one side of the upper heat sealing plate 30, or on both sides of the upper heat sealing plate 30 and the lower heat sealing plate 31.

[0034] A lower heat insulation block 37 is provided between the rotating pin 36 and the lower crossbar 38, which can be used for temperature insulation.

[0035] In this invention, a sealing position adjusting plate is connected to a fixed bracket 39. Sealing position adjusting plates 32 are respectively provided at the upper end of the upper heat-sealing plate and the lower end of the lower heat-sealing plate. More preferably, a plurality of adjusting screw holes 40 are provided at both ends of the sealing position adjusting plate 32, and a plurality of fixed screw holes corresponding to the adjusting screw holes are provided at both ends of the fixed bracket. (Refer to...) Figure 5 As shown, the upper and lower sealing plates are fixed to the fixed bracket 39 by the sealing position adjustment plate 32. When it is necessary to adjust the horizontal position, the sealing position adjustment plate 32 is moved to fix the adjusting screw hole 40 in another position to the fixed bracket 39, thereby realizing the adjustment of the horizontal position.

[0036] In this invention, the upper heat-sealing plate is provided with an upper heat insulation block 34, and the upper end of the upper heat-sealing plate is provided with an upper heat-sealing cylinder 28, and the lower end of the lower heat-sealing plate is provided with a lower heat-sealing cylinder 33. When the heat-sealing mechanism is in the open state, the bag containing the product reaches the sealing position, and the upper heat-sealing cylinder 28 and the lower heat-sealing cylinder 33 retract and close, heat-sealing the bag. The appropriate conditions for sealing the bag are achieved by adjusting the air pressure regulating valve 29, the temperature set by the temperature controller, and the heat-sealing time. The upper heat-sealing plate 30 and the lower heat-sealing plate 31 are indirectly connected to the cylinders through the upper heat insulation block 34 and the lower heat insulation block 37, respectively, to ensure that the heat-sealing temperature does not affect the normal operation of the cylinders and to improve the service life of other mechanical parts. The lower heat-sealing plate 31 is fixed by the rotating pin 36, and the balance adjustment screw 35 is used to adjust the balance in the Y-axis direction to ensure that the sealing surfaces of the upper heat-sealing plate 30 and the lower heat-sealing plate 31 fit well and ensure the flatness of the bag heat seal. The sealing position adjustment plate 32 can adjust the sealing mechanism in the horizontal direction, which facilitates the control of the appropriate sealing width of the bag and is compatible with the sealing width of different bags.

[0037] This invention's packaging machine solves the problems of slow speed, low automation, and inability to package many types of clothing, such as surgical gowns, especially when the packaging bag has different materials on both sides, requiring manual packaging. This invention utilizes two gripper cylinders, an upper opening cylinder, and a lower opening cylinder in the bag opening section, making it suitable for packaging of different materials. The two gripper cylinders also ensure that the bag seal is on a horizontal line during the gripping process, improving the product's pass rate during packaging. A pusher cylinder is located on the outside of the gripper cylinders, and a compression device is located on the inside. This system allows for adjustment of packaging bags of different sizes during the packaging process. The heat-sealing section, including an upper and lower heat-sealing plate, allows for adjustment of the heat-sealing position, accommodating products of various sizes. The bag-supporting section includes a bag-supporting cylinder, a linkage mechanism, a rotating shaft, and a bag-supporting plate. Under the action of the bag-supporting cylinder, the cylinder-supporting mechanism acts on the linkage mechanism, driving the rotating shaft to rotate, causing the bag-supporting plate connected to the rotating shaft to open, thus opening the bag and allowing the product to be smoothly pushed into it. The system features a simple structure, ingenious design, and minimal space occupation. The integrated bag-filling and opening mechanism, with its rotary opening method, saves considerable time.

[0038] The technical principles of the present invention have been described above with reference to specific embodiments, which are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments; all technical solutions falling within the scope of the present invention's concept are within its protection scope.
