Description

Technical Field

[0001] The invention relates to the technical field of packaging equipment, in particular to automatic bagging packaging equipment and a packaging method for leak-proof paper cup production. Background Art

[0002] The leak-proof paper cup is a specially designed paper cup with multi-layer composite materials or special coatings on the bottom and sides to effectively prevent liquid leakage. This paper cup is not only environmentally friendly, but also maintains structural stability when drinking hot and cold drinks. It is widely used in fast food restaurants, coffee shops and take-away beverage shops. The paper cup packaging machine is a mechanical equipment specially used to automatically count, stack and seal the finished paper cups with plastic packaging bags. It has the characteristics of simple operation and fast packaging speed.

[0003] Chinese patent CN114194488A discloses a paper cup packaging machine, which includes a frame, a feeding mechanism, a bagging mechanism and a bag feeding mechanism. The bagging mechanism is located on one side of the output end of the feeding mechanism, and the bag feeding mechanism is arranged on the side of the bagging mechanism away from the feeding mechanism. The feeding mechanism is designed with four feeding stations evenly distributed along the circumferential direction, and the angle between each adjacent station is 90°. This layout enables at least one feeding station to maintain a coaxial state with the bagging mechanism, thereby ensuring that the paper cups to be packaged can continuously enter the packaging process, significantly improving the packaging efficiency.

[0004] However, there are some shortcomings in this technology. After each single or multiple paper cups are packaged, a new packaging bag needs to be transported to the bagging mechanism through a bag feeding mechanism, and a special component is responsible for fixing the packaging bag and opening it to prepare for receiving the next paper cup. This process involves the operation of multiple mechanical drive components, including but not limited to the steps of bag transmission, positioning, opening and fixing, which not only increases the manufacturing cost, but also makes the operation of the entire system more complicated, which may lead to a higher failure rate and maintenance difficulty, affecting the overall stability and production efficiency of the production line.

DETAILED DESCRIPTION

A cutting knife 35 is arranged on the sealing component 3 close to the side of the support table 101. A first mounting frame 9 is fixedly installed on the support table 101, and a bag-supporting cylinder 8 is arranged on the first mounting frame 9. A plurality of limit bearings 10 are arranged on the first mounting frame 9 to limit the bag-supporting cylinder 8. The bag-supporting cylinder 8 is close to the limit bearing 10. The outer wall of the positioning bearing 10 is provided with a limiting groove matched with the limiting bearing 10, so that the bag-supporting tube 8 is limited on the first mounting frame 9, the bag-supporting tube 8 cannot rotate or move horizontally to a large extent, and the cylindrical packaging film can pass through the gap between the bag-supporting tube 8 and the limiting bearing 10, so that the cylindrical packaging film can be sleeved on the bag-supporting tube 8 and move. A plurality of notches 801 are provided on one side of the bag-supporting tube 8, and a support tube 5 is fixedly installed on the slide 102. A pushing mechanism for pushing the paper cup to move is provided on the slide 102. A clamping assembly 6 for clamping the packaging film at the notch 801 is provided on the side of the support tube 5 close to the bag-supporting tube 8. Two limiting rollers 23 for limiting the packaging film are installed on the support table 101. The outer diameter of the support tube 5 is slightly smaller than the inner diameter of the bag-supporting tube 8, so that the support tube 5 can just extend into the bag-supporting tube 8; During specific use, the cylindrical packaging film roll is installed on the feeding roller 7, and the packaging film is pulled out and passed through between the two limiting rollers 23, and then pulled onto the bag-supporting tube 8, so that the bag-supporting tube 8 stretches the packaging film into a cylindrical shape, and then the set of paper cups is placed on the pushing mechanism, and the support tube 5 is driven to move toward the bag-supporting tube 8 through the slide 102, so that the clamping assembly 6 moves to the notch 801 of the bag-supporting tube 8, and the packaging film at the notch 801 is clamped by the clamping assembly 6, and then the support tube 5 is driven by the slide 102 to move in the direction away from the bag-supporting tube 8, so that the packaging film is pulled out and a cylindrical packaging section is formed between the support tube 5 and the bag-supporting tube 8, and then the set of paper cups is pushed to move by the pushing mechanism, so that the paper cups pass through the support tube 5 and enter the packaging section between the support tube 5 and the bag-supporting tube 8, and after the pushing mechanism is reset, the two The sealing components 3 seal the two ends of the packaging section, and the paper cups are cut by the cutting knife 35 on the sealing components 3 close to the bag-supporting tube 8, so as to complete the bag packaging of the paper cups, and then the material can be unloaded by the unloading equipment; this scheme realizes the direct use of rolled cylindrical packaging film for packaging through the arrangement of the bag-supporting tube 8, the supporting tube 5, the sealing components 3 and the clamping components 6. In the initial stage, the packaging film only needs to be put on the bag-supporting tube 8. In the subsequent packaging, the packaging film only needs to be pulled out from the bag-supporting tube 8 through the supporting tube 5 and the clamping components 6. There is no need to transport, position, support and fix the packaging film, which simplifies the packaging process, reduces the number of mechanical drive components, and thus reduces the manufacturing cost. Due to the reduction in the number and complexity of the driving mechanical components, the operation of the entire system is more stable, and the failure rate and maintenance difficulty are reduced.

[0022] In this embodiment, preferably, the sealing assembly 3 includes a second mounting frame 31, a first cylinder 32, a mounting seat 33 and a hot-pressing sealing plate 34. The second mounting frame 31 is fixedly mounted on the top of the supporting frame 2. The position of the second mounting frame 31 can be adjusted to adjust the sealing position according to the length of the packaged set of paper cups. Two mounting seats 33 arranged opposite to each other are slidably mounted below the second mounting frame 31. The hot-pressing sealing plates 34 are fixedly mounted on the opposite side walls of the mounting seats 33. Two mounting seats 33 are fixedly mounted on the second mounting frame 31. The first cylinder 32 has two output ends which are fixedly connected to two mounting seats 33 respectively. The hot-pressing sealing plate 34 seals by squeezing and heating the packaging film. The hot-pressing sealing plate 34 is a prior art, and the specific principle is not described in detail here. The cutting knife 35 is fixedly mounted on the mounting seat 33 of the sealing assembly 3 close to the bag-supporting tube 8. The first cylinder 32 can drive the mounting seat 33 to move, thereby driving the hot-pressing sealing plate 34 to move. When the two phases are squeezed, the packaging film between them can be hot-pressed and sealed.

[0023] In this embodiment, preferably, the pushing mechanism includes a conveying trough 4, a second cylinder 21 and a pushing plate 22, the conveying trough 4 is fixedly installed on the top of the slide 102, one end of the conveying trough 4 is fixedly connected to the support tube 5, the second cylinder 21 is fixedly installed on the conveying trough 4, and the output of the second cylinder 21 is fixedly installed with a pushing plate 22; after placing a set of paper cups on the conveying trough 4, the pushing plate 22 can be driven to move by the output end of the second cylinder 21, so that the pushing plate 22 pushes the set of paper cups into the support tube 5.

[0024] In this embodiment, preferably, a sliding frame 12 is slidably installed on the support platform 101, and the sliding frame 12 passes through the support platform 101. A third cylinder 13 is fixedly installed below the support platform 101, and the output end of the third cylinder 13 is fixedly connected to the sliding frame 12. A fixing component for squeezing and fixing the packaging film is provided on the sliding frame 12; the fixing component includes a limiting frame 14, a fourth cylinder 15 and a pressing plate 16, and the limiting frame 14 is fixedly installed on the top of the sliding frame 12. When in use, the packaging film passes through the inside of the sliding frame 12, and the fourth cylinder 15 is fixedly installed on the top of the limiting frame 14, and the output end of the fourth cylinder 15 extends into the limiting frame A pressing plate 16 is fixedly installed on the inner side of the frame 14; when a group of paper cups is packaged, after the packaging film is cut off on the left side of the bag-supporting tube 8, the remaining packaging film will extend out of the bag-supporting tube 8 for a distance, making it inconvenient for the subsequent clamping assembly 6 to clamp the packaging film and causing a certain amount of packaging film waste. Therefore, after the packaging film is cut off, the pressing plate 16 can be driven downward by the output end of the fourth cylinder 15 to press the packaging film, and then the sliding frame 12 can be driven to move to the right by the third cylinder 13, pulling the packaging film on the bag-supporting tube 8 to move to the right for a distance, so that the left end of the packaging film is flush with the left side of the bag-supporting tube 8, thereby making it more convenient for the subsequent clamping assembly 6 to clamp the packaging film.

[0025] See also Figures 4 to 9 In the embodiment of the present invention, the clamping assembly 6 includes an installation box 61, a first connecting rod 64, a locking block 62 and a spring 63. The installation box 61 is fixedly connected to the support tube 5 through the first connecting rod 64. The locking block 62 partially extends into the installation box 61, and the locking block 62 and the installation box 61 are slidably matched. A spring 63 is arranged in the installation box 61. The locking block 62 is elastically connected to the installation box 61 through the spring 63. The side of the locking block 62 away from the installation box 61 is pressed on the outer peripheral wall of the support tube 5, and the side of the locking block 62 close to the bag support tube 8 is provided with an inclined surface. A window is opened on one side of the installation box 61, and a slider 65 is slidably arranged in the window. The slider 65 is fixedly connected to the locking block 62, and a first adjusting column 66 is rotatably installed on one side of the slider 65. A plurality of adjusting components 11 adapted to the first adjusting column 66 are arranged on the side of the first mounting frame 9 close to the support tube 5; The adjusting assembly 11 comprises a second connecting rod 117, an adjusting transverse plate 111 and an adjusting inclined plate 112, one end of the second connecting rod 117 is fixedly connected to the first mounting bracket 9, the side wall of the other end of the second connecting rod 117 is fixedly connected to the adjusting transverse plate 111, and the adjusting inclined plate 112 is elastically connected to the adjusting transverse plate 111 through a connecting member; the connecting member comprises a connecting block 113, a connecting cylinder 115, a connecting shaft 114 and a torsion spring 116, a groove is provided on the top of the adjusting transverse plate 111 near one end of the adjusting inclined plate 112, the connecting block 113 is arranged in the groove, and the connecting block 113 is fixedly connected to the adjusting inclined plate 112, The connecting shaft 114 passes through the connecting block 113 and is fixedly connected to the connecting block 113. Two connecting tubes 115 are provided and are arranged on both sides of the groove. The connecting tube 115 is fixedly connected to the adjusting cross plate 111. The two ends of the connecting shaft 114 extend into the two connecting tubes 115 respectively. The end of the connecting shaft 114 is sleeved with a torsion spring 116. One end of the torsion spring 116 is fixedly connected to the connecting shaft 114, and the other end of the torsion spring 116 is fixedly connected to the connecting tube 115. In the natural state, the adjusting inclined plate 112 can rotate relative to the adjusting cross plate 111 in the direction away from the bag supporting tube 8, and can be reset after the external force is removed under the action of the torsion spring 116.

[0026] In this embodiment, preferably, an adjusting ring 19 is sleeved on the support tube 5, and a second adjusting column 20 is rotatably installed on the top of the adjusting ring 19, the first connecting rod 64 passes through the adjusting ring 19, and the adjusting ring 19 and the first connecting rod 64 are slidably matched, and a traction rope 67 is fixedly connected to the top of the locking block 62, and one end of the traction rope 67 passes through the top wall of the installation box 61 and is fixedly connected to the adjusting ring 19; a third connecting rod 17 is fixedly installed on one of the mounting seats 33 close to the support tube 5, and the third connecting rod 17 is L-shaped. An inclined push plate 18 is fixedly installed on one side of 17. When the mounting seat 33 moves toward the packaging film for sealing, the inclined push plate 18 contacts the first adjusting column 66, so that the first adjusting column 66 moves along the inclined surface of the inclined push plate 18, thereby gradually pushing the adjusting ring 19 to move away from the mounting box 61, so that the traction rope 67 pulls the locking block 62 to move away from the support tube 5, thereby releasing the lock on the packaging film, so that after the packaging film is cut off, as the hot-pressing sealing plates 34 move away from each other, the packaged paper cups can fall downward to cooperate with the unloading equipment for unloading.

[0027] Specifically, when the support tube 5 moves toward the bag-supporting tube 8, as the first adjusting column 66 contacts the top wall of the adjusting inclined plate 112, under the action of the inclined surface of the top wall of the adjusting inclined plate 112, the first adjusting column 66 moves along the inclined surface, thereby driving the locking block 62 to move away from the support tube 5 through the slider 65, so that when the clamping assembly 6 moves into the notch 801, there is a certain gap between the locking block 62 and the tube wall of the support tube 5, so that the packaging film can enter the gap, and when the first adjusting column 66 passes over the adjusting transverse plate 111, the limiting position of the adjusting transverse plate 111 is lost. Under the elastic action of the spring 63, the locking block 62 and the first adjusting column 66 are reset, so that the locking block 62 is pressed on the packaging film, so that the packaging film is clamped between the locking block 62 and the supporting tube 5, and then the supporting tube 5 is controlled to move in the direction away from the bag-supporting tube 8. At this time, the first adjusting column 66 moves along the adjusting cross plate 111 and the adjusting inclined plate 112 close to the bag-supporting tube 8, so that the first adjusting column 66 does not move, so as to ensure that the locking block 62 always clamps the packaging film. When the first adjusting column 66 passes through the inner side of the adjusting inclined plate 112, under the action of the connecting piece, the adjusting inclined plate 112 can move to The outer side rotates so that the adjustment inclined plate 112 will not hinder the movement of the first adjustment column 66. When the support tube 5 moves to the left side of the sealing assembly 3 on the left, the two sealing assemblies 3 are used for sealing. At this time, the first cylinder 32 drives the mounting seat 33 to move, so that the two mounting seats 33 are close to each other. When the mounting seat 33 moves, the inclined push plate 18 is driven to move through the limit plate. After the inclined push plate 18 contacts the adjustment column, the adjustment column moves along the inclined surface of the inclined push plate 18, thereby gradually pushing the adjustment ring 19 to move in the direction away from the installation box 61, so that the traction rope 67 pulls the locking block 62 in the direction away from the installation box The support tube 5 moves in the direction of the support tube 5, thereby releasing the lock on the packaging film, so that after the packaging film is cut, as the hot-pressing sealing plates 34 move away from each other, the packaged paper cups can fall downward to cooperate with the unloading equipment for unloading. In this solution, the clamping component 6, the adjusting component 11, the adjusting ring 19 and the inclined push plate 18 cooperate with each other, so that the clamping component 6 moves to the side of the bag supporting tube 8 to automatically clamp the packaging film, and can automatically release the clamping of the packaging film during sealing. It is completely driven by the cooperation between mechanical structures, and there is no need to set up electrical driving elements for driving. It has good synchronization and low failure rate.

[0028] The present invention also discloses a method for packaging a leakage-proof paper cup, comprising the following steps: S1. The cylindrical packaging film roll is mounted on the feeding roller 7, the packaging film is pulled out from between the two limiting rollers 23, and then pulled onto the bag support tube 8, so that the bag support tube 8 opens the packaging film into a cylindrical shape; S2. Place the set of paper cups on the pushing mechanism, and drive the support tube 5 to move toward the bag-supporting tube 8 through the slide 102, so that the clamping assembly 6 moves to the notch 801 of the bag-supporting tube 8, and clamps the packaging film at the notch 801 through the clamping assembly 6, and then drive the support tube 5 to move away from the bag-supporting tube 8 through the slide 102, so that the packaging film is pulled out, and a cylindrical packaging section is formed between the support tube 5 and the bag-supporting tube 8; S3. The set of paper cups is pushed by the pushing mechanism to move, so that the paper cups pass through the supporting tube 5 and enter the packaging section between the supporting tube 5 and the bag-supporting tube 8. After the pushing mechanism is reset, the two ends of the packaging section are sealed by the two sealing components 3, and are cut by the cutting knife 35 on the sealing component 3 close to the bag-supporting tube 8.
