Abstract
Description
Technical Field
[0001] This utility model relates to the field of glove manufacturing technology, specifically an alternating feeding mechanism for glove manufacturing. Background Technology
[0002] In the field of dipped glove production, the traditional glove molding process has long relied on manual operation. For example, glove molding mainly involves manually slipping un-dipped knitted gloves onto the mold before the dipping production line automatically puts the gloves on for dipping. The core operation still requires manual intervention in slipping the gloves on. This traditional "manual" method is inefficient, costly, and the high-load, continuous operation easily leads to excessive strain on workers' bodies. It not only fails to improve production efficiency but also hinders the reduction of labor costs. Furthermore, it cannot better guarantee the consistency and quality of glove molding, and manual operation is difficult to control, mainly in the following aspects:
[0003] 1. Low production efficiency: Manual mold setting relies on workers' hand operations, which is limited by the frequency of human body movements (usually only 8-12 mold setting times per minute), making it difficult to meet the capacity requirements of large-scale production. Moreover, the speed of manual mold setting varies, and product quality is affected by the worker's skill level and working condition, making it difficult to guarantee consistency.
[0004] 2. High labor costs: The production of dipped gloves is a labor-intensive industry. A production line requires 6-12 mold-making workers. With the rising labor costs year by year, the cost disadvantage of traditional processes is becoming more and more obvious, and there are also problems such as difficulty in recruiting workers and long training cycles.
[0005] 3. High labor intensity and safety hazards: Long-term repetitive bending and raising of arms can easily lead to occupational health problems such as lumbar muscle strain and frozen shoulder in workers.
[0006] 4. Insufficient level of intelligence: Existing processes cannot be integrated with the factory's intelligent management system, lacking functions such as real-time monitoring of production data, fault early warning, and energy consumption analysis, making it difficult to meet the digital needs of modern intelligent manufacturing.
[0007] To address this, our company developed an automatic die-fitting device for glove production. This device requires an alternating feeding structure to facilitate material loading and allow workers to easily place and operate it. Utility Model Content
[0008] In order to solve the above problems, the purpose of this utility model is to provide an alternating feeding mechanism for glove production.
[0009] To achieve the above objectives, the technical solution of this utility model is as follows: an alternating feeding mechanism for glove production, comprising a feeding frame and an alternating moving frame that is slidably disposed within the feeding frame via slide rails and moves back and forth. A first feeding bin is slidably disposed on the top of the feeding frame via slide rails at its two ends. Vertical lifting racks are fixed at the bottom of both ends of a second feeding bin. The outer sides of each lifting rack are slidably connected to the sides of the alternating moving frame via vertical slide rails. Each lifting rack is driven to lift by the same driving device. Horizontal moving racks are respectively disposed on both sides of the feeding frame. The alternating moving frame is provided with a driving device for driving the alternating moving frame to move along the moving racks. A freely rotatable closed alternating belt is symmetrically disposed on the inner side of each end of the feeding frame. The two ends of the first feeding bin are fixedly connected to the upper rear side of the closed alternating belts on each side, and the two ends of the second feeding bin are fixedly connected to the lower front side of the closed alternating belts on each side.
[0010] Furthermore, the driving device for the lifting rack is a rack lifting drive shaft. At both ends of the rack lifting drive shaft, rack lifting drive gears that mesh with the lifting racks on each side are first fixed. Then, the two ends of the rack lifting drive shaft are rotatably mounted inside the side walls of the alternating moving frame. The rack lifting drive shaft is driven to rotate by a rack lifting motor fixed inside one side of the alternating moving frame.
[0011] Furthermore, the driving device for the moving rack is a frame moving drive shaft. The two ends of the frame moving drive shaft first rotate through the side walls of the alternating moving frame. Then, frame moving drive gears that mesh with the moving racks on each side are fixed at both ends of the frame moving drive shaft. The frame moving drive shaft is driven to rotate by a frame moving motor fixed inside one side of the alternating moving frame.
[0012] Furthermore, each of the four corners of the closed alternating belts on each side is supported by a freely rotatable alternating pulley, and the central fixed shaft of each alternating pulley is vertically and fixedly connected to the outer side wall of the feeding frame, with each alternating pulley rotating around its central fixed shaft.
[0013] Furthermore, each of the closed alternating belts on each side is provided with a tensioning wheel at one end for pressing that end of the closed alternating belt inward.
[0014] Furthermore, the main body of both the first and second feeding hoppers is a pallet structure, with U-shaped glove hoppers arranged in sequence fixed on the pallet structure, and the openings of the U-shaped glove hoppers facing outwards from the equipment.
[0015] Furthermore, each pallet structure is fixed with a horizontal bar and a vertical bar forming a bottom support frame for the hopper. The two ends of the bottom support frame of the first feeding hopper are fixedly connected to the corresponding parts of the closed alternating belt through bent fixed clamps. The two ends of the alternating moving frame are fixedly connected to the corresponding parts of the closed alternating belt through fixed clamps.
[0016] With the above configuration, during operation, while gripping gloves from the first feeding bin, the worker can place stacks of gloves into the U-shaped glove hopper of the second feeding bin. After the gloves from the first feeding bin are gripped, the gloves from the second feeding bin are also placed. At this point, the frame moving motor reverses, sending the second feeding bin back into the equipment, while the first feeding bin is pushed out again. Then, the rack and pinion lifting motor reverses, raising the second feeding bin to facilitate the gripping and walking mechanism to grip and feed the gloves placed on the second feeding bin. The worker then places stacks of gloves into the U-shaped glove hopper of the first feeding bin. This achieves alternating feeding between the first and second feeding bins. The worker only needs to alternately place gloves in the first and second feeding bins, which facilitates automated glove wrapping in conjunction with the subsequent gripping and walking mechanism, dynamic sorting mechanism, and glove molding mechanism, eliminating the need for manual wrapping. This alternating feeding structure not only has high alternation efficiency and a compact overall size with high space utilization, but it is also easy for workers to place, greatly improving the efficiency of alternating feeding.
[0017] This utility model employs a parallel double-track, single-servo belt drive, and synchronous drive devices on both sides of the synchronous rod to stabilize the transmission process. It rejects the traditional dual-cylinder synchronous structure, enabling continuous feeding of gloves to be molded and synchronous retrieval of empty molds. The feeding efficiency is increased by more than 300% compared to manual feeding. This device is easy to use with sensors, which monitor the material level in real time and automatically switch the feeding station, eliminating manual feeding intervals. Combined with a cycle control algorithm, it ensures that the equipment can run continuously for 24 hours without idling. Attached Figure Description

[0023] like Figure 1-4 As shown, an alternating feeding mechanism for glove production includes a feeding frame 101 and an alternating moving frame 102 that is slidably disposed within the feeding frame 101 and moves back and forth via slide rails. A first feeding bin 103 is slidably disposed on top of the feeding frame 101 via slide rails at its two ends. Vertical lifting racks 105 are fixed to the bottom of both ends of a second feeding bin 104. The outer sides of each lifting rack 105 are slidably connected to the sides of the alternating moving frame 102 via vertical slide rails. Each lifting rack 105 is driven by the same drive device. The lifting and lowering mechanism is equipped with horizontal moving racks 106 on both sides of the feeding frame 101. The alternating moving frame 102 is equipped with a driving device to drive the alternating moving frame 102 to move along the moving racks 106. The inner sides of each end of the feeding frame 101 are symmetrically equipped with freely rotatable closed alternating belts 107. The two ends of the first feeding bin 103 are fixedly connected to the upper rear side of the closed alternating belts 107 on each side, and the two ends of the second feeding bin 104 are fixedly connected to the lower front side of the closed alternating belts 107 on each side.
[0024] The specific driving devices are as follows: The driving device for the lifting rack 105 is a rack lifting drive shaft 108. At both ends of the rack lifting drive shaft 108, rack lifting drive gears 109 that mesh with the lifting racks 105 on each side are fixed. Then, the two ends of the rack lifting drive shaft 108 are rotatably disposed inside the side walls of the alternating moving frame 102. The rack lifting drive shaft 108 is driven to rotate by a rack lifting motor 110 fixed inside one side of the alternating moving frame 102. The driving device for the moving rack 106 is a frame moving drive shaft 111. At both ends of the frame moving drive shaft 111, frame moving drive gears 112 that mesh with the moving racks 106 on each side are fixed. The frame moving drive shaft 111 is driven to rotate by a frame moving motor 113 fixed inside one side of the alternating moving frame 102.
[0025] Each of the four corners of the closed alternating belt 107 on each side is supported by an alternating pulley 114 that can rotate freely, and the central fixed shaft of each alternating pulley 114 is vertically fixedly connected to the outer side wall of the feeding frame 101, and each alternating pulley 114 rotates around its central fixed shaft.
[0026] In order to further improve the tension of the closed alternating belt 107, a tensioning wheel 115 is provided at one end of each side of the closed alternating belt 107 to press that end of the closed alternating belt 107 inward.
[0027] The main body of the first feeding bin 103 and the second feeding bin 104 is a pallet structure. U-shaped glove bins 116 are fixed on the pallet structure in sequence, and the opening of the U-shaped glove bins 116 faces the outside of the equipment, that is, towards the workers.
[0028] To improve the support strength of each pallet structure, a bottom support frame 117 for the hopper is formed by a horizontal bar and a vertical bar fixedly connected below each pallet structure. The two ends of the bottom support frame 117 of the first feeding hopper 103 are fixedly connected to the corresponding parts of the closed alternating belt 107 through bent fixing plates 118. The two ends of the alternating moving frame 102 are fixedly connected to the corresponding parts of the closed alternating belt 107 through fixing plates 118.
[0029] Working principle of this utility model: This utility model is part of an automatic glove-making device, and is installed at the front end of the automatic glove-making device, i.e., the glove feeding end. The specific working process of the automatic glove-making device during alternating feeding is as follows:
[0030] In the initial state, the first feeding bin 103 and the second feeding bin 104 are located on the same horizontal plane, with the opening of the first feeding bin 103 facing outwards from the equipment, i.e., towards the worker placing the gloves. The worker first places stacks of gloves into the U-shaped glove hopper 116 of the first feeding bin 103. After feeding, the lifting rack 105 of the second feeding bin 104 moves downwards under the drive of the rack lifting motor 110, causing the rack lifting motor 110 to fall below the bottom of the first feeding bin 103. Then, the frame moving motor 113 operates, driving the entire alternating moving frame 102 to move outwards along the moving rack 106. Since the first feeding bin 103... Both ends of 03 are fixedly connected to the upper rear side of the closed alternating belt 107 on each side, and both ends of the second feeding bin 104 are fixedly connected to the lower front side of the closed alternating belt 107 on each side. When the alternating moving frame 102 moves outward along the moving rack 106, it also pulls the lower part of the closed alternating belt 107 outward, and the upper part of the closed alternating belt 107 moves upward. Thus, the upper part of the closed alternating belt 107 drives the first feeding bin 103 to move inward, so that the first feeding bin 103 is located inside the relative equipment. At this time, it is convenient for the gripping and walking mechanism of an automatic glove production mold-making device to place the first feeding bin. The first feeding bin 103 grabs a stack of gloves. Simultaneously, the second feeding bin 104 moves outward under the drive of the frame moving motor 113. While grabbing gloves from the first feeding bin 103, the worker can place the stack of gloves into the U-shaped glove hopper 116 of the second feeding bin 104. After the gloves from the first feeding bin 103 are grabbed, the gloves from the second feeding bin 104 are also placed. At this point, the frame moving motor 113 reverses its operation, sending the second feeding bin 104 back into the equipment, while the first feeding bin 103 is pushed outward again. Then, the rack and pinion lifting motor 110 reverses its operation, raising the second feeding bin 104 to facilitate the gripping and walking mechanism. The gloves on the second feeding bin 104 are gripped and fed, while the worker places the stack of gloves into the U-shaped glove hopper 116 of the first feeding bin 103. This allows for alternating feeding between the first feeding bin 103 and the second feeding bin 104. The worker only needs to alternately place the gloves on the first feeding bin 103 and the second feeding bin 104, which is convenient for cooperating with the subsequent gripping and walking mechanism, dynamic sorting mechanism and glove molding mechanism to achieve automated glove molding without manual molding. Moreover, this alternating feeding structure is not only highly efficient, compact in size and has high space utilization, but is also easy for workers to place, which can greatly improve the efficiency of alternating feeding.
[0031] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
