Description

Technical Field

[0001] The utility model relates to the technical field of chain packaging, in particular to a length-fixing mechanism for chain folding packaging. Background Art

[0002] The chain is a key component in the motorcycle transmission system. After the chain is produced, its length will be measured to see if it is qualified. Qualified chains will be folded back and forth from a straight and loose state into multiple sections to form a rotating snake shape to reduce the space occupied by the chain and enable the chain to be compactly packed into the packaging bag. However, different types of chains use different packaging bag specifications. Specifically, the overall length of the chain after folding is an important factor affecting whether the chain can be successfully bagged. The overall length after folding depends on the length of the initial segment of the chain. Other chain segments are bent according to the length of the initial segment. When folding the chain, the staff mainly visually evaluates the length of the initial segment of the chain and then begins to fold. The overall length of the chain after folding is prone to be too long or too short (increasing the overall width of the chain), which leads to subsequent failure to be successfully bagged.

[0003] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a fixed-length mechanism for chain folding packaging, which can accurately control the length of the initial cut section of the chain, thereby ensuring that the overall length of the chain after folding meets the requirements of a specific packaging bag and eliminating the human error caused by the staff's reliance on visual assessment of the chain length.

[0007] As a further improvement of the above technical solution, the first end block and the second end block are both composed of an upper flat bar, a vertical bar and a lower flat bar to form a C-shaped structure.

[0008] As a further improvement of the above technical solution, the lower flat bar is threadedly connected with a tightening screw facing the bottom surface of the table top.

[0009] As a further improvement of the above technical solution, the cross section of the guide rod is "D"-shaped, and the first end block and the second end block are provided with a plug hole with the same shape as the cross section of the guide rod.

[0010] As a further improvement of the above technical solution, the upper flat bar is threadedly connected with a fixing screw for pressing against the flat end surface of the guide rod.

[0011] As a further improvement of the above technical solution, the stopping structure is a stopping screw threadedly connected to the fixed-length block, and the stopping screw is pressed against the flat end surface of the guide rod.

[0012] As a further improvement of the above technical solution, the scale is provided on the flat end surface of the guide rod.

DETAILED DESCRIPTION

[0019] The utility model provides a length-fixing mechanism for chain folding packaging. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the protection scope of the utility model.

[0020] See also Figure 1-Figure 3 The utility model provides a fixed-length mechanism for chain folding packaging, which is arranged at the edge of a table board 1. The fixed-length mechanism includes a laterally extending guide rod 2, a fixed-length block 7 slidably arranged on the guide rod 2, and a first end block 3 and a second end block 4 respectively fixed to the two ends of the guide rod 2. The first end block 3 and the second end block 4 are fixed on the table board 1. A stop structure for limiting the movement of the fixed-length block 7 is provided on the fixed-length block 7. The spacing between the first end block 3 and the fixed-length block 7 is a fixed-length distance. A first magnetic plate 51 capable of magnetically attracting a chain 8 is provided on the side of the first end block 3 facing the fixed-length block 7. A second magnetic plate 52 capable of magnetically attracting a chain 8 is provided on the side of the fixed-length block 7 facing the first end block 3. A scale 21 is provided on the guide rod 2.

[0021] Before changing the packaging method of the chain 8 each time, the fixed length distance is adjusted accordingly. According to the fixed length distance and the scale 21 on the reference guide rod 2, the staff contacts the stop structure and moves the fixed length block 7 horizontally to a suitable position, so that the fixed length distance meets the requirements and then re-trigger the stop structure to fix the fixed length block 7. Then the staff temporarily fixes one end of the chain 8 to be packaged with the first magnetic plate 51 by magnetic attraction, and then the chain 8 is straightened into a straight line in the direction of the fixed length block 7 until the chain 8 is magnetically attracted by the second magnetic plate 52 to achieve the accurate length of the length of the initial intercepted segment, and then the chain 8 is folded into multiple segments to form a rotating snake shape, and finally the staff pushes the folded chain 8 forward, and the chain 8 is pushed away from the first magnetic plate 51 and the second magnetic plate 52, and finally the chain 8 is put into the packaging bag.

[0022] Compared with the prior art, the length-fixing mechanism provided by the utility model can accurately control the length of the initial cut section of the chain 8 through the set fixed length distance and the scale 21 on the guide rod 2, thereby ensuring that the overall length of the chain 8 after folding meets the requirements of a specific packaging bag, avoiding bagging difficulties caused by excessive length or too short length, and eliminating human errors caused by the staff's reliance on visual assessment of the length of the chain 8. In addition, the magnetic attraction of the first magnetic plate 51 and the second magnetic plate 52 can stably fix the two ends of the chain 8, ensuring that the chain 8 will not deviate during the straightening process, which not only reduces the difficulty of operation for the staff, but also ensures the accuracy of the fixed length.

[0023] Specifically, the first end block 3 and the second end block 4 are both composed of an upper flat bar 31, a vertical bar 32 and a lower flat bar 33 to form a C-shaped structure, and the lower flat bar 33 is threadedly connected with a tightening screw 61 facing the bottom surface of the table board 1. When installing the first end block 3 and the second end block 4, it is only necessary to insert the C-mouth into the edge of the table board 1, press the upper flat bar 31 on the table board 1, and then tighten the tightening screw 61 to fix the first end block 3 and the second end block 4 on the table board 1. By adjusting the tightness of the tightening screw 61, it can adapt to table boards 1 of different thicknesses, ensure the stable connection between the end block and the table board 1, and avoid loosening or falling off during use.

[0024] In this embodiment, the cross section of the guide rod 2 is "D" shaped, and the first end block 3 and the second end block 4 are provided with a socket 34 having the same cross section shape as the guide rod 2. By such a setting, the rotation of the guide rod 2 on the horizontal plane is effectively limited, the linear motion of the fixed-length block 7 during the movement is ensured, and the fixed-length accuracy and stability are improved. In addition, a scale 21 is provided on the flat end surface of the guide rod 2, and the flat end surface of the guide rod 2 faces the staff, ensuring that the staff can intuitively observe the scale 21.

[0025] Preferably, the upper flat bar 31 is threadedly connected with a fixing screw 62 for pressing against the flat end surface of the guide rod 2. The fixing screw 62 directly acts on the flat end surface of the guide rod 2. By adjusting the tightness of the fixing screw 62, the guide rod 2 can be effectively fixed to the upper flat bar 31, preventing the guide rod 2 from unnecessary displacement or shaking during use, thereby ensuring the stable operation of the fixed length mechanism. When the guide rod 2 needs to be maintained or replaced, the guide rod 2 can be easily disassembled by simply loosening the fixing screw 62, which not only simplifies the maintenance process, but also facilitates the cleaning or inspection of the guide rod 2, ensuring that the equipment remains in good working condition for a long time.

[0026] Preferably, the stop structure is a stop screw 63 threadedly connected to the fixed length block 7, and the stop screw 63 is pressed against the flat end surface of the guide rod 2. The stop screw 63 directly contacts the flat end surface of the guide rod 2 and applies pressure, which can accurately locate the position of the fixed length block 7 on the guide rod 2. Once the stop screw 63 is tightened, the fixed length block 7 can be firmly locked to prevent it from being displaced during the stretching or folding process of the chain 8, thereby ensuring the accuracy of the length of the initial intercepted section of the chain 8.

[0027] In order to allow the operator to quickly adjust the position of the fixed-length block 7, reduce the difficulty of operation, and omit the assistance of tools, the stop screw 63 is preferably a hand screw, which can specifically be a plum hand screw and a clevis hand screw.

[0028] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0029] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the utility model, and all these changes or substitutions should fall within the protection scope of the utility model.
