Description

Technical Field

[0001] This invention relates to a packaging machine, specifically a high-speed paper cup-to-bag packaging machine and its packaging method. Background Technology

[0002] The paper cup bag packaging machine is an automated packaging equipment specifically designed for disposable paper cups, paper bowls and other cup-shaped products. It uses pre-made bags (such as CPP colored film, PE composite bags, etc.) and feeds bags from the bag hopper, opens the bags, fills the cups, seals them and outputs them, achieving efficient, aesthetically pleasing and hygienic finished product packaging.

[0003] Bag storage is used to transport packaging bags one by one. Existing bag storage generally has a bag placement position. Workers place stacked packaging bags in the bag placement position. The bottom of the bag placement position is equipped with a limit part, which is generally a flat structure, so that the gripping unit can grab a packaging bag and pull it out. However, when the support area of ​​the flat structure is small, the stacked packaging bags are prone to sagging in the middle. If the support area of ​​the flat structure is large, on the one hand, more vertical space is required when the packaging bags are pulled out, and on the other hand, the packaging bags are prone to wear and tear.

[0004] Secondly, the bag placement area is generally used for placing multiple layers of packaging bags. Due to gravity, the friction between the bottom few packaging bags is relatively large. When the gripping unit grabs the bottom packaging bag and pulls it down, it is easy to cause the second to last packaging bag to move a certain distance. At the same time, multiple packaging bags at the bottom may also shift slightly, causing the stacked packaging bags to fall more in the middle. This can easily result in two or more packaging bags falling out when the gripping unit pulls down, affecting subsequent processes such as opening and bagging. Summary of the Invention

[0005] The purpose of this invention is to provide a high-speed paper cup-to-bag packaging machine and its packaging method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-speed paper cup bag-feeding packaging machine, comprising a bag magazine, the bag magazine including a first frame and a mounting frame mounted on the first frame, the mounting frame having at least two bag placement positions; further comprising a bag feeding assembly and a negative pressure gripping assembly corresponding to the bag placement positions, the negative pressure gripping assembly being used to grip a single packaging bag on the bag placement position and place it on the bag feeding assembly; the bottom of the bag placement position having a receiving assembly for receiving the packaging bag, the receiving assembly comprising: a receiving frame having a fixed extension plate and a movable extension plate capable of rotating relative to the fixed extension plate, a notch being formed between the fixed extension plate and the movable extension plate, a rotating roller rotatably mounted on the movable extension plate protruding from the upper surface of the fixed extension plate; a driving unit being used to engage with the rotating roller when the movable extension plate is rotated to a horizontal position to drive the rotating roller to rotate, and when the movable extension plate rotates from a horizontal position to an inclined position, the rotating roller disengages from the driving unit.

[0007] As described above, in the high-speed paper cup to bag packaging machine: two vertically symmetrical mounting plates are fixed on the fixed extension plate, and an arc-shaped guide groove is formed on the vertical mounting plate; the rotating shaft of the roller passes through the arc-shaped guide groove and can move along the arc-shaped guide groove; when the rotating shaft of the roller rotates downward along the arc-shaped guide groove, the roller gradually moves away from the drive unit.

[0008] The paper cup to bag high-speed packaging machine described above: the drive unit includes: a connecting shaft rotatably mounted on two of the vertical mounting plates, the connecting shaft being driven to rotate by a drive source mounted on one of the vertical mounting plates; a first gear fixed on the connecting shaft and a second gear fixed on the rotating roller, wherein the second gear meshes with the first gear when the movable extension plate is in a horizontal position.

[0009] In the paper cup to bag high-speed packaging machine described above: the axis of the arc-shaped guide groove is located below the axis of the connecting shaft.

[0010] The paper cup to bag high-speed packaging machine described above: a movable rod is fixed on the movable extension plate, and the rotating shaft of the roller is rotatably connected to the movable rod; a movable sleeve is rotatably installed on the connecting shaft, and the end of the movable rod away from the movable extension plate is inserted into the movable sleeve and can slide directionally along the movable sleeve; a second cylinder is hinged on the receiving frame, and the movable end of the second cylinder is hinged to the movable sleeve.

[0011] The paper cup to bag high-speed packaging machine described above includes: a fourth gear coaxially fixed with the first gear and a third gear rotatably mounted on a vertical mounting plate, the third gear meshing with the fourth gear; it also includes a second motor mounted on the vertical mounting plate, the output shaft of the second motor being coaxially fixed with the third gear.

[0012] The paper cup bag feeding high-speed packaging machine described above: the bag feeding assembly includes: a first rotating shaft and a second rotating shaft rotatably mounted on the first frame, two strip conveyor belts connected between the first rotating shaft and the second rotating shaft, and multiple protrusions equidistantly formed on the strip conveyor belts, with a conveying position for limiting the packaging bag formed between two adjacent protrusions.

[0013] The paper cup feeding bag high-speed packaging machine described above: the negative pressure gripping assembly includes: a support frame fixed to the first frame, on which a first cylinder is mounted; and a movable frame, which is mounted on the movable end of the first cylinder, and on which multiple negative pressure heads are mounted.

[0014] The paper cup-to-bag high-speed packaging machine described above further includes: a bag opening mechanism for unfolding the bag opening of the packaging bag conveyed from the bag warehouse and conveying it laterally; a bag fitting mechanism for inserting the packaging bag conveyed from the bag opening mechanism to keep the packaging bag in an open state; a cup feeding mechanism for conveying multiple rows of cups; a cup pushing mechanism for pushing multiple rows of cups facing the packaging bag into the packaging bag on the bag fitting mechanism; a heat sealing mechanism for sealing the packaging bag containing multiple rows of cups and transferring it laterally; and a bag conveying mechanism for receiving the sealed packaging bag and sending it out of the packaging machine.

[0015] A high-speed paper cup-to-bag packaging method, using the aforementioned high-speed paper cup-to-bag packaging machine, includes the following steps: a bag warehouse delivers packaging bags one at a time to the bag opening mechanism, the bag opening mechanism opens the packaging bags and then places them onto a bag-fitting mechanism, the bag-fitting mechanism then rotates to a position aligned with the cup-feeding mechanism, the cup-pushing mechanism pushes multiple rows of paper cups into the packaging bags, and pushes the packaging bags containing the paper cups to the heat-sealing mechanism for sealing, and after sealing, the packaging bags containing the paper cups are sent out of the packaging machine through a bag-forming conveyor mechanism to complete the packaging.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: When the packaging bag is pulled down, the movable extension plate drives the rotating roller to rotate downward, thereby increasing the passage area of ​​the bag placement position to facilitate the pulling out of the packaging bag. At the same time, when the movable extension plate rotates downward, the rotating roller disengages from the drive unit and rotates freely. When the packaging bag is pulled down, the friction force on the packaging bag can be reduced, which can play a certain protective role for the packaging bag. Secondly, after a packaging bag is discharged, the movable extension plate returns to the horizontal state, supports the packaging bag again, and provides a relatively large support area. At the same time, the rotating roller reconnects with the drive unit, and the drive unit can drive the rotating roller to rotate to generate a pulling force in the opposite direction on the packaging bag, thereby flattening the packaging bag and eliminating the phenomenon of the packaging bag at the bottom sagging in the middle to a certain extent, ensuring that only one packaging bag is pulled out at a time.

Detailed Implementation

[0036] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0037] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0038] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0039] Please see Figures 1-2 In this embodiment of the invention, a high-speed paper cup-to-bag packaging machine includes: a bag magazine 1 for conveying packaging bags; a bag opening mechanism 3 for unfolding the bag opening of the packaging bags conveyed from the bag magazine 1 and conveying them laterally; a bag fitting mechanism 6 for inserting the packaging bags conveyed from the bag opening mechanism 3 to keep the packaging bags in an open state; a cup feeding mechanism 5 for conveying multiple rows of cups; a cup pushing mechanism 7 for pushing multiple rows of cups facing the packaging bags into the packaging bags on the bag fitting mechanism 6; a heat sealing mechanism 8 for sealing the packaging bags containing multiple rows of cups and transferring them laterally; and a bag conveying mechanism 2 for receiving the sealed packaging bags and sending them out of the packaging machine.

[0040] The paper cup bag-type high-speed packaging machine also includes a housing 4. The bag opening mechanism 3, bag putting mechanism 6, cup pushing mechanism 7 and heat sealing mechanism 8 are located inside the housing 4. The bag storage 1 and the discharge end of the cup feeding mechanism 5 extend into the housing 4. The bag forming conveying mechanism 2 is set on the side of the housing 4 and is located at the discharge end of the heat sealing mechanism 8.

[0041] Specifically: Please refer to Figures 3-11 The bag storage unit 1 includes a first frame 101 and a mounting frame 102 mounted on the first frame 101. The mounting frame 102 has at least two bag placement positions 104. Support legs are mounted on the first frame 101 to support it and maintain its horizontal position. It also includes a bag feeding assembly 103 and a negative pressure gripping assembly 105 corresponding to each bag placement position 104. The negative pressure gripping assembly 105 grips a single packaging bag from the bag placement position 104 and places it onto the bag feeding assembly 103. A receiving assembly 106 for receiving the packaging bag is formed at the bottom of each bag placement position 104. The receiving assembly 106 includes a fixed... The fixed extension plate 1062 includes a receiving frame 1061 and a movable extension plate 1063 that can rotate relative to the fixed extension plate 1062. A notch 10616 is formed between the fixed extension plate 1062 and the movable extension plate 1063. A rotating roller 10613, which is rotatably mounted on the movable extension plate 1063, protrudes from the upper plane of the fixed extension plate 1062. A driving unit is used to engage with the rotating roller 10613 when the movable extension plate 1063 is rotated to a horizontal position to drive the rotating roller 10613 to rotate. When the movable extension plate 1063 rotates from a horizontal position to an inclined position, the rotating roller 10613 disengages from the driving unit.

[0042] It should be noted that the bottom of each bag placement position 104 is provided with two sets of receiving components 106, which are used to support the bottom of both ends of the packaging bag.

[0043] In this embodiment, multiple stacked packaging bags are placed on the bag placement position 104. Two sets of receiving components 106 support the bottom of the packaging bags. When a packaging bag needs to be grasped, the negative pressure grasping component 105 moves upward and grasps the bottommost packaging bag, then pulls it downward. As the packaging bag is pulled downward, the movable extension plate 1063 drives the rotating roller 10613 to rotate downward, thereby increasing the passage area of ​​the bag placement position 104 to facilitate the pulling out of the packaging bag. Simultaneously, as the movable extension plate 1063 rotates downward, the rotating roller 10613 disengages from the drive unit, allowing it to rotate freely. When the packaging bag is pulled downward... This reduces the friction on the packaging bag, providing some protection. Secondly, after one packaging bag is discharged, the movable extension plate 1063 returns to a horizontal position, supporting the packaging bag again and providing a relatively large support area. At the same time, the rotating roller 10613 reconnects with the drive unit, which can drive the rotating roller 10613 to rotate, generating a pulling force in the opposite direction on the packaging bag (the two rotating rollers 10613 on the two sets of supporting components 106), thus flattening the packaging bag and eliminating the phenomenon of the packaging bag at the bottom sagging in the middle to a certain extent, ensuring that only one packaging bag is pulled out at a time.

[0044] It should be further explained that the bag placement position 104 is formed by two first baffles 1041 and two second baffles 1042, so that multiple stacked packaging bags are placed in a relatively flat state.

[0045] In one embodiment, two bag placement positions 104 are provided along the conveying direction, and each bag placement position 104 is provided with a material storage photoelectric sensor on its side. For ease of explanation, the two bag placement positions 104 are defined as: bag placement position one and bag placement position two. In the initial state, both bag placement positions one and bag placement position two are stacked with packaging bags. The negative pressure gripping component 105 located below bag placement position one first performs the bag gripping action. When the packaging bags in bag placement position one are used up, the material storage photoelectric sensor on bag placement position one detects a signal, and the system automatically switches to the negative pressure gripping component 105 below bag placement position two to perform the bag gripping work. At the same time, the system alarms to remind the operator to replenish the material in bag placement position one. When the packaging bags in bag placement position two are used up, the same operating logic is executed, and the system switches back to bag placement position one.

[0046] Further, please refer to Figures 8-11 Two vertically symmetrical mounting plates 1064 are fixed on the fixed extension plate 1062. An arc-shaped guide groove 10610 is formed on the vertical mounting plate 1064. The rotating shaft of the rotating roller 10613 passes through the arc-shaped guide groove 10610 and can move along the arc-shaped guide groove 10610. When the rotating shaft of the rotating roller 10613 rotates downward along the arc-shaped guide groove 10610, the rotating roller 10613 gradually moves away from the driving unit.

[0047] The arc-shaped guide groove 10610 limits the movement trajectory of the movable extension plate 1063 and the rotating roller 10613 when the movable extension plate 1063 rotates, ensuring the stability of the movement of the movable extension plate 1063 and the rotating roller 10613, and at the same time, it ensures that the rotating roller 10613 has a guiding drive away from the drive unit when it follows the movable extension plate 1063 to rotate downward.

[0048] Please refer to the figure. Figures 8-11 The drive unit includes: a connecting shaft 10614 rotatably mounted on the two vertical mounting plates 1064, the connecting shaft 10614 being driven to rotate by a drive source mounted on one of the vertical mounting plates 1064, the rotation center of the movable extension plate 1063 coinciding with the rotation center of the connecting shaft 10614; a first gear 1065 fixed on the connecting shaft 10614 and a second gear 1066 fixed on the rotating roller 10613, the second gear 1066 meshing with the first gear 1065 when the movable extension plate 1063 is in a horizontal position.

[0049] When the movable extension plate 1063 is in a horizontal position, the first gear 1065 and the second gear 1066 mesh, and the connecting shaft 10614 is driven to rotate by the set drive source. Under the action of the first gear 1065 and the second gear 1066, the connecting shaft 10614 drives the rotating roller 10613 to rotate. The rotating roller 10613 drives the packaging bag in contact with it to move towards the fixed extension plate 1062, thereby realizing the straightening and placement of the packaging bag.

[0050] It should be noted that since the rotating roller 10613 protrudes from the upper surface of the fixed extension plate 1062, there is a certain pressure between the rotating roller 10613 and the packaging bag, which prevents the rotating roller 10613 from continuously rotating relative to the packaging bag and affecting the straightening effect on the packaging bag. At the same time, when the movable extension plate 1063 rotates downward, the rotating roller 10613 serves as the main contact point with the packaging bag, thereby reducing the wear caused by the contact between the packaging bag and the end of the movable extension plate 1063.

[0051] The first gear 1065 mentioned above is a large gear, and the second gear 1066 is a small gear. When the rotating roller 10613 rotates downward with the movable extension plate 1063, the second gear 1066 can quickly disengage from the first gear 1065, thereby reducing the space occupied by the second gear 1066.

[0052] The axis of the arc-shaped guide groove 10610 is located below the axis of the connecting shaft 10614, so that when the rotating roller 10613 rotates downward with the movable extension plate 1063, the rotating shaft of the rotating roller 10613 gradually moves away from the connecting shaft 10614, thereby causing the second gear 1066 to disengage from the first gear 1065.

[0053] Further, please refer to Figures 10-11 A movable rod 10612 is fixed on the movable extension plate 1063, and the rotating shaft of the rotating roller 10613 is rotatably connected to the movable rod 10612; a movable sleeve 10611 is rotatably mounted on the connecting shaft 10614, and one end of the movable rod 10612 away from the movable extension plate 1063 is inserted into the movable sleeve 10611 and can slide directionally along the movable sleeve 10611; a second cylinder 1067 is hinged on the receiving frame 1061, and the movable end of the second cylinder 1067 is hinged to the movable sleeve 10611.

[0054] When the second cylinder 1067 extends or retracts, it drives the movable sleeve 10611 to rotate around the circumference of the connecting shaft 10614. When the movable sleeve 10611 rotates, it drives the movable rod 10612, which is slidably connected to it, to rotate synchronously, thereby driving the rotating roller 10613 and the movable extension plate 1063 to rotate. At the same time, the movable rod 10612 moves away from the movable sleeve 10611 under the action of the rotating shaft of the rotating roller 10613 and the arc-shaped guide groove 10610, so as to realize the movement of the rotating roller 10613, thereby making the meshing or disengagement between the second gear 1066 and the first gear 1065 smoother and more stable.

[0055] Please see Figures 8-11 In one embodiment, the drive source includes: a fourth gear 1069 coaxially fixed with the first gear 1065 and a third gear 1068 rotatably mounted on a vertical mounting plate 1064, wherein the third gear 1068 meshes with the fourth gear 1069; it also includes a second motor 10615 mounted on the vertical mounting plate 1064, wherein the output shaft of the second motor 10615 is coaxially fixed with the third gear 1068.

[0056] When the second motor 10615 is activated, it drives the third gear 1068 to rotate. The third gear 1068, through the meshing fourth gear 1069, drives the connecting shaft 10614 to rotate, thereby fulfilling the driving requirement.

[0057] Please see Figures 3-7The first frame 101 has a strip-shaped through groove 1011, and the bag feeding assembly 103 protrudes from the strip-shaped through groove 1011. Specifically, the bag feeding assembly 103 includes a first rotating shaft 1031 and a second rotating shaft 1032 rotatably mounted on the first frame 101. Two strip-shaped conveyor belts 1033 are connected between the first rotating shaft 1031 and the second rotating shaft 1032. A plurality of protrusions 1034 are formed equidistantly on the strip-shaped conveyor belts 1033, and a conveying position for limiting the packaging bag is formed between two adjacent protrusions 1034.

[0058] The second rotating shaft 1032 is driven to rotate by the first motor 1035 mounted on the first frame 101, thereby cooperating with the first rotating shaft 1031 to realize the conveying action of the strip conveyor belt 1033. The conveying position formed by the protrusion 1034 can prevent relative displacement between the packaging bag and the strip conveyor belt 1033, ensuring that the packaging bag can be conveyed smoothly.

[0059] It should be noted that pulleys for use with the strip conveyor belt 1033 are installed on both the first rotating shaft 1031 and the second rotating shaft 1032. In order to ensure the stability of the strip conveyor belt 1033, the strip conveyor belt 1033 is a toothed belt, and the pulley is a toothed pulley that cooperates with the toothed belt.

[0060] Please see Figure 4 , Figure 6 and Figure 7 The negative pressure gripping component 105 includes: a support frame 1051 fixed to the first frame 101, on which a first cylinder 1052 is mounted; and a movable frame 1053, which is mounted on the movable end of the first cylinder 1052, and on which a plurality of negative pressure heads 1054 are mounted.

[0061] The movable frame 1053 is located between two strip conveyor belts 1033, and when the first cylinder 1052 extends, it can drive the movable frame 1053 to pass through the gap between the two strip conveyor belts 1033. When it is necessary to grab a packaging bag, the movable frame 1053 drives multiple negative pressure heads 1054 to move upward. When the negative pressure head 1054 comes into contact with the packaging bag, the negative pressure machine connected to the negative pressure head 1054 is activated, so that the negative pressure head 1054 and the packaging bag are attracted by negative pressure. Then, under the action of the first cylinder 1052, the movable frame 1053 drives the negative pressure head 1054 and a packaging bag to move downward. When the packaging bag moves to the conveying position, the negative pressure machine releases the negative pressure, the negative pressure head 1054 separates from the packaging bag, and the strip conveyor belt 1033 sends the packaging bag away, thereby realizing the conveying action of the packaging bag.

[0062] Please see Figures 1-2 and Figure 12The bag opening mechanism 3 includes a sliding frame 308 slidably mounted on the housing 4. Two negative pressure suction cups 301 are symmetrically arranged on one side of the sliding frame 308. An eccentric frame 303 is fixed to the end of the negative pressure suction cup 301 facing the sliding frame 308. The lower eccentric frame 303 (defined as the first eccentric frame) is fixed on the sliding frame 308, and the upper eccentric frame 303 (defined as the second eccentric frame) is rotatably mounted on the sliding frame 308 at the end away from the negative pressure suction cup 301. The mechanism also includes a third cylinder 304 hinged to the sliding frame 308. The movable end of the third cylinder 304 is hinged to the end of the second eccentric frame near the negative pressure suction cup 301. The included angle between the third cylinder 304 and the eccentric frame 303 is greater than 0°.

[0063] When the third cylinder 304 performs the telescopic action, it can drive the second eccentric frame to rotate, thereby realizing the separation or docking of the two negative pressure suction cups 301. When the opening position of the packaging bag moves between the two negative pressure suction cups 301, the upper negative pressure suction cup 301 swings towards the lower negative pressure suction cup 301. When both negative pressure suction cups 301 are in contact with the packaging bag, the air pipe 302 connecting the negative pressure suction cups 301 works with the negative pressure machine to generate negative pressure in the negative pressure suction cups 301, thereby fixing the negative pressure suction cups 301 to the packaging bag. Then the third cylinder 304 acts again, driving the eccentric frame 303 to drive the two negative pressure suction cups 301 to separate. Since the second eccentric frame is in a rotating state, it can generate a bag-rubbing effect on the packaging bag when the opening of the packaging bag is opened, thereby facilitating the opening of the packaging bag.

[0064] Furthermore, a transmission belt assembly 306 is rotatably mounted on the housing 4. The transmission belt assembly 306 is driven by a third motor 305 mounted on the housing 4. A connecting block 307 fixed to the sliding frame 308 is fixed on the transmission belt assembly 306.

[0065] Two negative pressure suction cups 301 open the bag opening and remain connected to the bag. Then, the third motor 305 drives the transmission belt assembly 306 to move, thereby driving the entire assembly on the sliding frame 308 to move laterally through the connecting block 307, so as to put the bag onto the bagging mechanism 6.

[0066] It should be noted that the transmission belt assembly 306 includes two toothed pulleys and a toothed belt fitted on the two toothed pulleys, and the connecting block 307 is fixed on the toothed belt.

[0067] Please see Figures 1-2 and Figure 13 and Figure 14The bagging mechanism 6 includes a fixed frame 604 fixed on the housing 4 and a rotating mounting frame 602 rotatably mounted on the fixed frame 604. The rotating mounting frame 602 is driven to rotate by a fourth motor 603 mounted on the fixed frame 604. The rotating mounting frame 602 has two bagging positions on the side facing the bag opening mechanism 3, and two bag supporting parts 601 are symmetrically installed on the bagging positions.

[0068] After the packaging bag is fitted onto the support member 601 in one of the bag-fitting positions, the fourth motor 603 drives the rotating mounting bracket 602 to rotate, causing the other bag-fitting position to rotate to a position directly opposite the bag-opening mechanism 3. The bag-fitting position with the packaging bag is rotated to a position directly opposite the cup-pushing mechanism 7, thereby realizing the switching of the two bag-fitting positions. The two bag-fitting positions alternately receive the packaging bag, which can effectively reduce the time wasted in the bag-fitting process and effectively improve packaging efficiency.

[0069] Please see Figures 1-2 as well as Figure 15 The cup feeding mechanism 5 includes a third frame 501 and a second conveyor belt assembly 502 mounted on the third frame 501. The second conveyor belt assembly 502 has multiple V-shaped receiving parts 503 evenly spaced on it. The paper cups, which are stacked together, are placed on the V-shaped receiving parts 503. Then the second conveyor belt assembly 502 moves to transport the paper cups, which can eliminate the phenomenon of paper cups rolling and shifting during the transport process.

[0070] Please see Figures 1-2 as well as Figure 16 The cup-pushing mechanism 7 includes a sliding seat 701 slidably mounted on the housing 4 and a cup-pushing rod 702 mounted on the sliding seat 701. It also includes a driving component for driving the sliding seat 701 to slide laterally. This driving component is the same as the driving structure for driving the sliding frame 308 to move as described above. Therefore, this embodiment will not describe it in detail.

[0071] When the cup feeding mechanism 5 delivers multiple rows of paper cups to the position directly opposite the bagging position, the drive component drives the sliding seat 701 to move, thereby driving the cup pusher 702 to move, thus pushing the multiple rows of paper cups into the packaging bag.

[0072] Please see Figures 1-2 as well as Figure 17 The heat sealing mechanism 8 includes a fourth frame 804 and two heat sealing components 801 slidably mounted on the fourth frame 804. The two heat sealing components 801 are driven by a drive component 802 mounted on the fourth frame 804. The drive component 802 is used to drive the two heat sealing components 801 to separate or contact in the vertical direction.

[0073] A transfer conveyor belt 803 is also provided on the side of the fourth frame 804 away from the cup feeding mechanism 5. The transfer conveyor belt 803 is used to receive the packaging bags (including paper cups) during heat sealing and to transfer the packaging bags (including paper cups) to the bag conveying mechanism 2 after heat sealing.

[0074] The fourth frame 804 is also symmetrically equipped with two telescopic pushers 805 on the side facing the transfer conveyor belt 803. The two telescopic pushers 805 are used to straighten the packaging bag (including paper cup) and ensure the straightness of the packaging bag opening during heat sealing.

[0075] Please see Figures 1-2 as well as Figure 18 The bag conveying mechanism 2 includes a second frame 201 and a first conveyor belt assembly 202 installed on the second frame 201. Side baffles 203 are also installed on the second frame 201 at positions on both sides of the first conveyor belt assembly 202. The heat-sealed packaging bags (including paper cups) are conveyed to the first conveyor belt assembly 202 by the transfer conveyor belt 803 and then sent out through the first conveyor belt assembly 202.

[0076] As another embodiment of the present invention, a high-speed packaging method for paper cups fed into bags is also proposed. The method uses the paper cup feeding bag high-speed packaging machine described above and includes the following steps: the bag warehouse 1 transports packaging bags one at a time to the position of the bag opening mechanism 3. The bag opening mechanism 3 opens the packaging bags and then puts them onto the bag fitting mechanism 6. Subsequently, the bag fitting mechanism 6 rotates to a position aligned with the cup feeding mechanism 5. The cup pushing mechanism 7 pushes multiple rows of paper cups into the packaging bags and pushes the packaging bags containing paper cups to the heat sealing mechanism 8 for sealing. After sealing, the packaging bags containing paper cups are sent out of the packaging machine through the bag conveying mechanism 2 to complete the packaging.

[0077] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0078] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
