Description

Technical Field

[0001] This invention relates to the field of paper cup packaging technology, specifically to a fully automated packaging mechanism for paper cup production. Background Technology

[0002] An automatic paper cup packaging machine is a specialized piece of equipment designed for the automatic packaging of paper cups. It efficiently completes the packaging process, including forming, bottom sealing, side curling, top shaping, and packaging. A paper cup packaging machine typically consists of the following main parts: Paper cup forming section: This section feeds in cardboard and, through a specific forming process, transforms the cardboard into a cylindrical shape, forming the basic structure of the paper cup; Bottom sealing section: The bottom of the formed paper cup is sealed in this section, usually using hot or cold pressing to ensure a tight seal; Side curling section: This section curls the edges of the paper cup to increase its strength and stability; Top shaping section: This section shapes and trims the top of the paper cup to ensure a neat appearance and a flat top; Packaging section: Finally, the paper cups are packaged by the packaging machine, either by placing them in cartons or by wrapping them in packaging film before batching or bagging.

[0003] Existing packaging machines transport paper cups to the inside of packaging boxes by using suction cups on the bottom plate to adhere the stacked paper cups. However, since there are gaps between each stacked paper cup, the suction cups are not strong enough, so stability cannot be guaranteed during transportation. Furthermore, the stacked paper cups are long and the paper is soft, so the middle paper cups are bent when lifted by suction. If stability cannot be guaranteed, the middle paper cups are prone to breaking or falling off.

[0004] In view of this, the present invention solves the above-mentioned technical problems by proposing a fully automated packaging mechanism for paper cup production. Summary of the Invention

[0005] To address the shortcomings of the aforementioned background technology, this invention provides a technical solution for a fully automatic packaging mechanism for paper cup production. This mechanism can adjust the packaging parameters of the packaging box and transport the paper cups into the box in a concentrated manner. At the same time, it stabilizes the paper cups during transportation, preventing the stacked paper cups from breaking due to their softness during transportation. This solves the problems mentioned in the background technology.

[0006] This invention provides the following technical solution: a fully automatic packaging mechanism for paper cup production, comprising a machine body, a fixed frame fixed to one end of the top of the machine body, and a control terminal inside the machine body; a drive motor, which is slidably mounted on the top of the fixed frame, and a connecting frame driven by the output end of the drive motor at its bottom; and a centralized cup-carrying mechanism located below the drive motor. This mechanism can adjust and centrally transport paper cups into the packaging box according to the packaging parameters, while stabilizing the paper cups during transport to prevent breakage due to softness in the stacked cups during transport. The centralized cup-carrying mechanism includes a base plate, a pressure sensor mounted on the bottom of the base plate, and multiple base plates, with both ends of the base plate fixed to the bottom of the connecting frame. Multiple sets of gripping claws are slidably installed on the bottom of the base plate. A limit block is fixed to the bottom of the base plate, and a groove II is opened on the surface of the limit block. The top of the gripping claw passes through the interior of the base plate through the groove II. A spring I is fixed inside the groove II of the limit block. A locking block I is fixed to the end of the spring I. The locking block I is rotatably connected to the part of the top of the gripping claw located in the groove II, which can increase the force-bearing area of ​​the top of the gripping claw and improve the stability of the gripping claw when moving. Multiple sets of soft strips are fixed to the outer wall of each gripping claw. Stacked paper cups can be gripped and transported to the packaging box by two gripping claws. The soft strips contact the surface of the paper cup to stabilize the state of the paper cup during transportation and prevent the paper cup from deforming. A placement rack is fixed to one side of the machine body. Multiple isolation rollers are rotatably installed inside the placement rack in a row.

[0007] As a preferred embodiment of the present invention, multiple telescopic rods with telescopic function are hinged to both ends of the base plate, and the end of one of the telescopic rods is sleeved on the bottom of the connecting frame. The base plate can be adjusted according to the number of packages by means of the telescopic rod.

[0008] As a preferred embodiment of the present invention, the bottom of the clamping claw is slidably connected to a plurality of sliding shafts via a sliding groove I, the surface of the sliding shafts is fitted with rotating balls, and a spring IV is connected inside the sliding groove I, with the spring IV connected to the sliding shaft.

[0009] As a preferred embodiment of the present invention, the top of the clamping claw is rotatably connected to a gear inside the base plate, the surface of the gear is meshed with a rack, both ends of the rack extend to the outside of the base plate, and a cylinder is fixed to the end of one of the racks, the number of racks corresponding to the base plate.

[0010] As a preferred embodiment of the present invention, a connecting block is fixed to the end of the rack, and elastic blocks I are elastically connected to both sides of the inner wall of the connecting block by elastic elements. A rotating wheel is rotatably connected to the surface of the elastic block I, and a round block is fixed to the other end of the rack. An elastic block II is elastically slidably connected inside the round block.

[0011] As a preferred embodiment of the present invention, the elastic element includes a spring II, which is located inside the connecting block and connected to the elastic block I. The surface of the elastic block II is inclined and is clamped on both sides of the rotating wheel so that the racks inside the other base plates are connected.

[0012] As a preferred embodiment of the present invention, a fixing block is fixed to the inner wall of the gear, and a locking block II is connected to the inside of the clamping claw via a spring III. When the clamping claw moves, the gear can rotate along the surface of the rack to facilitate the adjustment of the distance between the two clamping claws according to the diameter of the paper cup.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] When multiple sets of paper cups are clamped by the gripper, the stacked paper cups can be transported in multiple layers according to the height of the packaging box. At the same time, the soft strips on the outer wall of the gripper can hold and fix the paper cups during transportation, avoiding instability and improving packaging efficiency.

[0015] By slidingly connecting spring I with the limiting block, the distance between two adjacent gripping claws can be adjusted according to the diameter of the paper cup. The soft strip on the surface of the gripping claw has a certain degree of flexibility, which can prevent the paper cup from being deformed when it is gripped. At the same time, the pointed tip at the bottom of the gripping claw can be directly inserted between two paper cups, and the inclined surface of the lower surface of the gripping claw can push the ungripped paper cup to both sides, preventing the two paper cups from being deformed due to being too close together.

[0016] By moving spring IV within the groove I at the bottom of the gripper to increase the distance between the two balls, the friction between the gripper and the paper cup is reduced when the bottom of the gripper contacts the paper cup, preventing the paper cup from being deformed by pressure. Furthermore, the sliding of the sliding shaft within the groove I allows it to adjust automatically according to the diameter of the paper cup.

[0017] The meshing of the rack and pinion drives the gear and the gripper to rotate, causing the soft strip on the surface of the gripper to separate from the surface of the paper cup. The paper cup falls automatically as the distance between the two grippers increases, so that the paper cup is neatly placed inside the packaging box, enabling automatic and neat packaging of paper cups.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0031] Please see Figure 1-2 and Figure 6-8 As shown, a fully automatic packaging mechanism for paper cup production includes a machine body 1, a fixed frame 3 fixed at one end of the top of the machine body 1, a control terminal inside the machine body 1, a drive motor 401, the drive motor 401 is slidably mounted on the top of the fixed frame 3, and a connecting frame 402 is driven and mounted at the bottom output end of the drive motor 401.

[0032] The centralized cup-carrying mechanism is located below the drive motor 401. It can adjust and transport paper cups into the packaging box according to the packaging parameters of the packaging box. At the same time, it can stabilize the paper cups during transportation and prevent the middle of the stacked paper cups from breaking due to their softness.

[0033] Paper cups are conveyed from the top of the machine body 1 and placed on the top of the placement rack 2. Then, the connecting frame 402 is driven by the drive motor 401 to lift the base plate 4. The stacked paper cups are then clamped and transported by the clamping claw 403.

[0034] The centralized cup-carrying mechanism includes a base plate 4, with a pressure sensor installed on the bottom of the base plate 4. Multiple base plates 4 are present, and both ends of the base plate 4 are fixed to the bottom of the connecting frame 402. Multiple sets of clamping claws 403 are slidably mounted on the bottom of the base plate 4. A limit block 408 is fixed to the bottom of the base plate 4, and a groove II is formed on the surface of the limit block 408. The top of the clamping claws 403 penetrates the interior of the base plate 4 through the groove II. A spring I 4031 is fixed inside the groove II of the limit block 408, and a locking block I is fixed to the end of the spring I 4031. The locking block I and the clamping claws 403... The top part located in the slide groove II is rotatably connected, which can increase the force-bearing area of ​​the top of the gripper 403 and improve the stability of the gripper 403 when moving. Each gripper 403 has multiple sets of soft strips fixed on its outer wall. The stacked paper cups can be gripped and transported to the packaging box by two gripper 403s. The soft strips contact the surface of the paper cup to stabilize the state of the paper cup during transportation and prevent the paper cup from deforming. A placement rack 2 is fixed on one side of the machine body 1. Multiple isolation rollers 201 arranged in a row are rotatably installed inside the placement rack 2.

[0035] The base plate 4 is driven to rise and fall repeatedly. During the repeated rise and fall, the base plate 4 continuously clamps the paper cups through the clamping claws 403. First, the clamped paper cup is located on the lower surface of the clamping claws 403. The second clamped paper cup will push the first clamped paper cup upward. This process continues, causing the previously clamped paper cups to move upward continuously. This allows for multi-layer stacking and transportation of the stacked paper cups according to the height of the packaging box. At the same time, the soft strips on the outer wall of the clamping claws 403 can clamp and fix the paper cups during transportation, preventing instability during transportation and improving packaging efficiency.

[0036] When the two gripping claws 403 come into contact with the paper cup, they are slidably connected to the limiting block 408 via the spring I 4031. The spacing between the two adjacent gripping claws 403 can be adjusted according to the diameter of the paper cup. Furthermore, the soft strip on the surface of the gripping claws 403 has a certain degree of flexibility, which can prevent the paper cup from deforming when it is gripped.

[0037] When the gripper 403 grips the paper cup, the pointed tip at the bottom of the gripper 403 can be inserted directly between the two paper cups. At the same time, the inclined surface of the lower surface of the gripper 403 can push the ungripped paper cups to both sides to prevent the two paper cups from being deformed due to being too close together.

[0038] Example 2, based on Example 1:

[0039] Please see Figure 2-3 6-7 and Figure 9 As shown, in a specific embodiment of the present invention, multiple telescopic rods 404 with telescopic function are hinged to both ends of the base plate 4. The end of one of the telescopic rods 404 is sleeved on the bottom of the connecting frame 402. The base plate 4 can be adjusted according to the packaging quantity through the telescopic rod 404. Multiple sliding shafts 4035 are slidably connected to the bottom of the clamping claw 403 through the sliding groove I 4034. The surface of the sliding shaft 4035 is covered with rotating ball bearings 4036. A spring IV 4037 is connected inside the sliding groove I 4034. The spring IV 4037 is connected to the sliding shaft 4035.

[0040] When the gripping claws 403 rise and fall with the base plate 4, when the two gripping claws 403 grip the paper cup, the ball bearings 4036 at the bottom of the gripping claws 403 rotate when they come into contact with the paper cup. At the same time, the interaction force generated by the gripping claws 403 and the paper cup causes the sliding shaft 4035 and the ball bearings 4036 to move in the sliding groove I 4034 at the bottom of the gripping claws 403 through the spring IV 4037, increasing the distance between the two ball bearings 4036. This reduces the friction between the bottom of the gripping claws 403 and the paper cup when they come into contact, preventing the paper cup from being deformed by pressure. Furthermore, the sliding of the sliding shaft 4035 in the sliding groove I 4034 can adjust itself according to the diameter of the paper cup.

[0041] When only one row of paper cups is packed vertically inside the packaging box, the base plate 4 can be stacked and stored using the telescopic rod 404. Conversely, when there are many packaging items inside the packaging box, the base plate 4 can be unfolded using the telescopic rod 404. The telescopic rod 404 allows the number of base plates 4 to be adjusted according to the number of items being packaged.

[0042] Example 3, based on Examples 1 and 2:

[0043] Please see Figure 4-5 and Figure 10 As shown, in a specific embodiment of the present invention, a gear 407 is rotatably connected to the top of the gripping claw 403 inside the base plate 4. A rack 406 meshes with the surface of the gear 407. Both ends of the rack 406 extend to the outside of the base plate 4. A cylinder 409 is fixed to the end of one of the racks 406. The number of racks 406 corresponds to the number of base plates 4. A connecting block 405 is fixed to the end of the rack 406. An elastic block I 4051 is elastically connected to both sides of the inner wall of the connecting block 405 through an elastic element. A rotating wheel 4052 is rotatably connected to the surface of the elastic block I 4051. A round block 4053 is fixed to the other end of the rack 406. The round block 4053 has an elastic block II 4054 that is elastically slidably connected inside; the elastic element includes spring II, which is located inside the connecting block 405 and connected to elastic block I 4051. The surface of elastic block II 4054 is inclined and clamps on both sides of the rotating wheel 4052 so that the rack 406 inside the other base plate 4 is connected; a fixing block 4071 is fixed to the inner wall of the gear 407; a clamping block II 4038 is telescopically connected inside the clamping claw 403 through spring III; when the clamping claw 403 moves, the gear 407 can rotate along the surface of the rack 406 so that the distance between the two clamping claws 403 can be adjusted according to the diameter of the paper cup.

[0044] When there are many packages inside the packaging box, each base plate can be unfolded, as shown in the reference. Figure 4-5 As shown, when the base plate 4 unfolds, the round block 4053 at the end of the rack 406 is engaged with the surface of the elastic block I 4051 inside the connecting block 405, and then clamped to the surface of the rotating wheel 4052 by the elastic block II 4054, so that the racks 406 inside the two or more base plates 4 are connected to the same plane. When the paper cup is transported and placed inside the packaging box by the base plate 4, the pressure sensor at the bottom of the first base plate 4 contacts the top of the box opening and transmits the signal to the central control terminal. The central control terminal controls the cylinder 409 to drive the rack 406 to move back and forth inside the base plate 4. The rack 406 meshes with the gear 407, which drives the gear 407 and the clamping claw 403 to rotate, so that the soft strip on the surface of the clamping claw 403 separates from the surface of the paper cup. The paper cup falls automatically as the distance between the two clamping claws 403 increases, so that the paper cup is neatly placed inside the packaging box, which can automatically and neatly arrange and package the paper cup.

[0045] By setting the rotating wheel 4052, when the round block 4053 and the elastic block II 4054 are connected to the connecting block 405, the rotating wheel 4052 rotates due to friction, which can reduce the friction when the round block 4053 is stuck inside the connecting block 405, making it easier to engage with the inside of the connecting block 405.

[0046] By using the inclined surface at the end of the elastic block II 4054, the rotating wheel 4052 can push the elastic block II 4054 to both sides when it contacts the elastic block II 4054, so that the elastic block II 4054 is clamped on both sides of the rotating wheel 4052. This increases the stability when each rack 406 is connected together, and can package different numbers of paper cups while making them fall down automatically and neatly.

[0047] It should be noted that when the gripper 403 moves inside the limiting block 408, the gear 407 meshes with the rack 406 and rotates tightly against the surface of the rack 406. The fixing block 4071 at the bottom of the gear 407 rotates with the gear 407. When the fixing block 4071 passes the locking block II 4038, it pushes the locking block II 4038 to move into the gripper 403, so as to avoid the gripper 403 being blocked during movement. When the gripper 403 stops moving, the gear 407 stops rotating. The fixing block 4071 is locked between the two locking blocks II 4038. When the rack 406 meshes with the gear 407, the entire gripper 403 and the gear 407 can rotate to make the paper cup fall automatically.

[0048] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Additionally, in the accompanying drawings of this invention, the fill patterns are merely for distinguishing layers and do not constitute any other limitation.
