Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a compaction component. Background Technology

[0002] In the packaging of products in the food, daily necessities and other fields, there is often a special type of packaging structure. Its exterior is a long, tapered paper tube. The smaller end of the paper tube is closed, while the larger end is open. During the packaging process, the material to be packaged must first be filled into the paper tube, and then the larger end is processed to complete the sealing.

[0003] To ensure the stability of the packaging structure, improve the neatness of the product appearance, and enhance the compactness of the material inside the paper tube to avoid problems such as loosening or displacement of the material during subsequent transportation and storage, it is necessary to press down the closed part of the large end of the paper tube to form a pressure indentation with a specific depth requirement at that end.

[0004] Currently, the industry almost entirely relies on manual operation for the aforementioned pressing process, where operators use simple tools (such as small pressure blocks, tweezers, etc.) to press the end of the paper tube. However, this manual operation method has insurmountable drawbacks: First, the pressure and angle of manual pressing rely entirely on the operator's experience and feel, making precise control impossible. This easily leads to problems such as insufficient material compaction due to shallow indentations, or damage to the paper tube and deformation of the material due to excessive pressure, severely affecting the consistency of product packaging quality and potentially causing substandard products to enter the market. Second, the efficiency of manual operation is extremely low. A single operator can only complete the pressing of a small number of paper tubes per minute, far from meeting the demands of large-scale mass production and restricting the overall production line's capacity improvement. Third, the pressing operation is a repetitive mechanical action, and prolonged operation can easily lead to hand fatigue and muscle strain for operators, further reducing the efficiency and quality stability of subsequent operations and posing certain occupational health risks. Fourth, during manual operation, deviations in the placement of the paper tubes and the direction of force applied during pressing can easily occur, potentially causing the sealing structure at the end of the paper tube to loosen, or even causing the entire paper tube to tip over and spill material, increasing production losses and rework costs.

[0019] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] Please see Figure 1 This application provides the following technical solutions: A compaction assembly includes a support structure 1, a positioning mechanism 2, and a compaction mechanism 3. The support structure 1 serves as the basic support for the entire assembly, and includes a fixed support structure 11 and a movable support structure 12. The fixed support structure 11 is fixedly connected to an external structure, and the movable support structure 12 is slidably connected to the fixed support structure 11, allowing the movable support structure 12 to rise or fall vertically.

[0021] The fixed support structure 11 is a portal frame, comprising a horizontally arranged top frame 111, with a side frame 112 at each end of the top frame 111 along its length, extending downwards from the top frame 111. A base frame 113 is provided at the bottom of each side frame 112, extending inwards from the fixed support structure 11. In this design, both the top frame 111 and the side frames 112 are made of plate. The base frame 113 includes a horizontal plate, and a reinforcing plate, which is a right-angled triangular plate, is provided between the base frame 113 and the side frames 112 as a reinforcing structure.

[0022] A guide structure 13 is provided inside the fixed support structure 11. The guide structure 13 guides in a vertical direction. The movable support structure 12 is slidably connected to the fixed support structure 11 through the guide structure 13. The guide structure 13 can take various forms; in this scheme, the guide structure 13 is a guide rod. The guide structure 13 includes two vertical guide rods. The outer side of the guide rod is slidably connected to the movable support structure 12 through a sliding sleeve. The upper end of the guide rod is connected to the top frame 111, and the lower end is connected to the base frame 113.

[0023] The positioning mechanism 2 is connected to the movable support structure 12, and the positioning mechanism 2 moves synchronously with the movable support structure 12. The positioning mechanism 2 can apply a horizontal supporting force to the periphery of the bag opening position to be compacted. The compaction mechanism 3 is located above the positioning mechanism 2. The compaction mechanism 3 includes a compaction component 31, which is a structure that can extend and retract in the vertical direction. The fixed structure of the compaction component 31 is connected to the movable support structure 12 and moves synchronously with the movable support structure 12. The movable structure of the compaction component 31 can extend downward toward the fixed structure, and the bottom end of the movable structure of the compaction component 31 corresponds to the shape of the bag opening to be compacted.

[0024] When the packaging bag that needs to be compacted during processing moves to the working position of the compaction component in this solution, the movable support structure 12 moves downward, the positioning mechanism 2 positions the opening of the packaging bag, and then the compaction component 31 of the compaction mechanism 3 moves downward, pressing down on the opening of the packaging bag with the assistance of the positioning mechanism 2, thereby completing the compaction operation.

[0025] Based on the above implementation scheme, the movable support structure 12 includes a movable frame 121 and a fixed frame 122. Both the movable frame 121 and the fixed frame 122 are horizontally oriented frames; the movable frame 121 is slidably connected to the fixed support structure 11 via a guide structure 13; the fixed frame 122 is fixedly positioned below the movable frame 121. The movable frame 121 includes a horizontal frame plate, which is a rectangular plate, and the inner surface of the side frame 112 is a vertical plane; both ends of the frame plate of the movable frame 121 are in contact with the inner surface of the side frame 112. The positioning mechanism 2 is connected to the fixed frame 122, and the compaction mechanism 3 is connected to the movable frame 121.

[0026] With this structure, the movable frame 121 can be raised and lowered stably in cooperation with the guide rod, the frame plate and the side frame 112, thereby ensuring the accurate working position of the subsequent positioning and compaction actions.

[0027] Based on the above implementation scheme, the support mechanism 1 also includes a lifting drive structure 14 that is linked with the movable support structure 12. The lifting drive structure 14 is used to drive the movable support structure 12 to rise or fall.

[0028] The lifting drive structure 14 includes a lifting motor 141, a synchronization component 142, and a linkage rod 143. The lifting motor 141 serves as the power source for the lifting drive structure 14 and is fixedly mounted on the upper side of the top frame 111 via a motor mount. The synchronization component 142 is a combination of a synchronization pulley and a synchronization belt. Two sets of synchronization components 142 are provided, each linked to both sides of the movable frame 121. Each synchronization component 142 includes two synchronization pulleys and a synchronization belt. The two synchronization pulleys are rotatably connected to the upper and lower sides of the fixed support structure 11, respectively, and the synchronization belt surrounds the two synchronization pulleys. The movable frame 121 is fixedly connected to the belt body. The synchronization pulley located on the upper side of the fixed support structure 11 is linked to the lifting motor 141. Furthermore, the two synchronization pulleys on the upper side of the two synchronization components 142 are linked by the linkage rod 143, which is a horizontally positioned rod with its two ends coaxially fixedly connected to the two synchronization pulleys.

[0029] Based on the above implementation plan, see Figures 2 to 5The positioning mechanism 2 includes a first positioning structure 21 and a second positioning structure 22. The first positioning structure 21 is fixedly installed at the lower part of the movable support structure 12; the first positioning structure 21 has a plurality of positioning holes arranged in a linear array; the second positioning structure 22 is connected to the first positioning structure 21, and the second positioning structure 22 includes two positioning plates 221 arranged below the first positioning structure 21. There are two positioning plates 221 symmetrically arranged, and the two positioning plates 221 can move closer to each other or further away from each other. A plurality of positioning grooves are opened on the opposite side of the two positioning plates 221. The positioning grooves are semi-circular slots, and the positioning grooves correspond to the positioning holes; when the two positioning plates 221 are in contact, the positioning grooves on the two positioning plates 221 can be combined to form a circular hole.

[0030] Considering the issue that the paper bag opening of the long cone shape is relatively soft and easily deformed, two different positioning methods are combined to position the bag opening. The inner diameter of the fixed positioning hole is large to ensure that the bag opening can pass through. The positioning plate 221 is used to clamp it on the lower side to further ensure the stability of the position where the bag opening needs to be pressed, thereby avoiding deformation and damage to the bag opening position during the pressing process.

[0031] Based on the above implementation scheme, the positioning mechanism 2 also includes a positioning drive structure 23, which drives the two positioning plates 221 to merge or separate. In this scheme, the positioning drive structure 23 is a drive cylinder 231, which is a bidirectional cylinder. Its cylinder body is fixed on the first positioning structure 21, and the two movable ends of the cylinder are respectively connected to a drive frame 232. The lower ends of the two drive frames are respectively connected to the positioning plates 221.

[0032] The opening and closing of the positioning plate 221 is achieved by driving the cylinder 231 and the drive frame 232.

[0033] Based on the above implementation plan, see Figures 6 to 9 The compaction component 31 of the compaction mechanism 3 is a round rod with a compaction groove at its bottom end. The groove is an upward-recessed bowl-shaped groove. This is because paper bags are often sealed at the ends through twisting during packaging, forming a twisted structure at the bag's opening. Conventional pressure head structures might cause excessive pressure on the twisted portion of the bag or damage the twisted structure. Therefore, the compaction component 31 in this design has a groove at its end. This groove creates space to avoid the twisted portion of the bag, while the downward pressure is achieved solely through the groove's periphery. This circumferential downward pressure simultaneously drives the twisted structure at the bag's seal downwards, achieving simple compaction of the internal material.

[0034] Based on the above implementation scheme, the compaction mechanism 3 also includes a compaction drive component 32, which is a cylinder, and its movable end is fixedly connected to the upper end of the compaction component 31. A compaction positioning component 33 is slidably sleeved on the outside of its movable end. The compaction positioning component is a sleeve structure, and its outer wall is fixedly connected to the movable frame 121. This achieves stable positioning of the compaction action.
