Description

Technical Field

[0001] To improve production efficiency and automate production, this invention provides a bag clamping mechanism for automated material filling production. Using this mechanism, products can be fixed, transported, and positioned, thereby improving production efficiency and product uniformity and consistency. Background Technology

[0002] This series of products contains a cloth bag inside the cartridge. The cloth bag is available in single-chamber and multi-chamber versions, and includes various forms such as square, round, and strip-shaped bags. The material is waterproof cotton cloth, cotton fabric, etc. It contains a fixed amount of granules, and it is required that the granules in each chamber of the multi-chamber bag be uniform. Currently, the bags are made of cotton fabric and have a multi-cavity ring structure. During the granule filling process, the granules need to be filled separately and then sewn together. During the granule filling process, it is necessary to ensure that the granules inside the bag are compact and of basically uniform height. The sewing should be tight and free of skipped stitches, loose threads, piled threads, or slippage. The beginning and end of the sewing should be backstitched twice to ensure that the threads do not come loose. After sewing, the basic bags need to be turned inside out and hand-sewn to maintain a certain rigidity. Because the bags are made of cotton fabric, the material is soft, and the granule filling accuracy is not easy to control. During the sewing process, problems such as wrinkles at the bag opening, slanted threads, and skipped stitches are very likely to occur. Automatic bag loading, high-precision granule weighing, and automatic sewing are the difficulties in the automatic bag manufacturing process. There are many on-site operators. Due to the limitations of the bag material and structure, it is very difficult to reduce the number of personnel on the production line. This is a common problem in the industry and is difficult to automate.

[0003] Therefore, in order to improve the production efficiency of cloth bags, it is necessary to rigidly fix the multi-cavity cloth bags around their perimeter. This mechanism is used to fix, transport, and position the products, thereby improving production efficiency and product uniformity and consistency. Summary of the Invention

[0004] The technical solution adopted by this invention to solve its technical problem is: a bag clamping mechanism for automatic filling production, characterized in that: the mechanism consists of a clamping mechanism, a hooking mechanism, and an unloading mechanism; the clamping mechanism consists of a bracket, a base, a fixing frame, a feed pipe, a shaped clamp, and quick clamps, which can fix the bag, making the bag change from flexible to rigid, facilitating subsequent steps; the hooking mechanism consists of a hooking module, a connecting plate, a pneumatic gripper, and a clamping hook, in which the bracket and the fixing frame have mating holes corresponding to the clamping grooves, when the clamping hook clamps the corresponding hole of the bracket, the clamping mechanism can be lifted and transported to other positions, when the clamping hook clamps the corresponding hole of the fixing frame, the fixing frame can be lifted and transported to other positions; the unloading mechanism consists of an unloading module and a pressure plate, the pressure plate has 4 protrusions corresponding to 4 quick clamps on the fixing frame, when the pressure plate is pressed down, the clamps can be released, and then the hooking mechanism is used to transport the fixing frame to other positions, facilitating the next process.

[0014] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0015] exist Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 In this process, the bag clamping mechanism consists of a clamping mechanism, a hooking mechanism, and an unloading mechanism.

[0016] The clamping mechanism consists of a base 1, a shaped clamp 2, a bracket 3, a quick-release caliper 4, a feed tube 5, and a fixing frame 6. The shaped clamp 2 is fixed to the base 1 with set screws, the bracket 3 is fixed to the base 1 with screws, the quick-release caliper 4 is fixed to the fixing frame 6 with screws, and the feed tube 5 is welded to the fixing frame 6. The fixing frame 6 and the bracket 3 are fixed together by a groove. After the clamping mechanism is assembled, the cloth bag is manually placed on the clamping mechanism, and each feed port on the cloth bag is inserted into the feed tube. In the subsequent feeding process, the particles enter each feed port of the cloth bag from the feed tube. The quick-release caliper is used to fix the upper edge of the cloth bag, and then the cloth bag hangs down naturally. The shaped clamp is used to clamp the lower part of the cloth bag. The V-shaped groove of the shaped clamp can play a positioning role. In the hemming and sewing process, the needle and thread pass through the middle.

[0017] The hooking mechanism consists of a clamping hook 7, a pneumatic gripper 8, a connecting plate 9, and a hooking module 10. The clamping hook 7 is fixed to the pneumatic gripper 8 with screws, and the pneumatic gripper 8 and the connecting plate 9 are fixed to the hooking module 10 with screws. When the clamping mechanism needs to be moved, the hooking module moves downward into position, the clamping hook is flush with the mounting hole, the pneumatic gripper opens, the clamping hook clamps the mounting, and the hooking module moves upward to lift the clamping mechanism. Together with other conveying mechanisms, the clamping mechanism is moved to the designated position. When the fixed frame needs to be unloaded, the hooking module moves downward into position, the clamping hook is flush with the mounting hole, the pneumatic gripper opens, the clamping hook clamps the fixed frame, and the hooking module moves upward to lift the fixed frame. Together with other conveying mechanisms, the fixed frame is moved away.

[0018] The unloading structure consists of a pressure plate 11 and an unloading module 12. The pressure plate 11 is fixed to the unloading module 12 with screws. When the mounting bracket needs to be unloaded, the quick-release caliper must be released first. The unloading module moves downward first, and the pressure plate is used to release the quick-release caliper. The pressure plate has 4 protrusions that correspond to the position of the quick-release caliper, which ensures that the quick-release caliper is released without contacting other mechanisms.

[0019] All equivalent technical variations described in the specification and illustrations of this invention are included within the scope of protection of this invention.
