Description

Technical Field

[0001] The utility model belongs to the technical field of hardware fastener production, and particularly relates to a sorting and recycling device for die-castings of hardware fasteners. Background Art

[0002] Hardware fasteners generally refer to various metal fasteners, and are involved in a relatively wide range of fields, including luggage, clothing, shoe materials, leather goods, etc. For example: hardware belt buckles, hardware dog buckles, hardware pin buckles, hardware day buckles, hardware square buckles, hardware buttons, hardware snap fasteners, hardware double buckles, hardware round buckles, etc. Each component of the hardware fastener can be integrally formed by die-casting. During the production process of die-castings of hardware fasteners, it is necessary to separate different die-castings connected together, and then sort the separated die-castings. A sorting and recycling device is required for sorting the die-castings.

[0003] Most of the existing technologies are sorted manually. It is necessary to manually disassemble the die-castings connected together and then sort them, resulting in low sorting and recycling efficiency. Moreover, there are many impurities in the sorted die-castings of hardware fasteners. It is necessary to remove the smaller impurities doped in the die-castings of hardware fasteners, which is rather inconvenient. Content of the Utility Model

[0004] To solve the problems raised in the above background art, the utility model provides a sorting and recycling device for die-castings of hardware fasteners, which has the characteristics of improving the sorting and recycling efficiency of die-castings of hardware fasteners and facilitating the removal of smaller impurities.

[0005] To achieve the above object, the utility model provides the following technical solution: A sorting and recycling device for die-castings of hardware fasteners, including a frame. A conveyor belt is arranged inside the frame. A number of die-castings of hardware fastener bodies are placed on the conveyor belt. A separation and sorting assembly is arranged above the die-castings of hardware fastener bodies. Two recycling bins are arranged below one end of the conveyor belt. The bottom of the recycling bin is movably connected with a bottom plate. An impurity removal assembly is arranged inside the recycling bin.

[0006] As a further scheme of the utility model: The separation and sorting assembly includes a connecting frame, a separation cylinder, a cutting knife, a limit motor, a limit screw rod, a driving frame and a pressing plate. Among them, a connecting frame is arranged at the upper end of one side of the frame. A separation cylinder is arranged at the bottom of the connecting frame. A cutting knife is arranged at the lower end of the separation cylinder. A limit screw rod is arranged at the upper end of the connecting frame. A limit motor is arranged at the upper end of the limit screw rod. A driving frame is threadedly connected to the surface of the limit screw rod. A pressing plate is arranged at the lower end of the driving frame.

[0007] As a further solution of the present utility model: A buffer spring is connected between the driving frame and the pressing plate. A limiting post is slidably connected between the buffer spring and the driving frame. The buffer spring and the limiting post prevent the main body of the hardware buckle casting from being deformed due to excessive pressure of the pressing plate.

[0008] As a further solution of the present utility model: Partition plates are provided on one side of the recycling bins close to each other. The partition plates separate the two recycling bins, preventing different hardware buckle castings from falling into the same-side recycling bin and improving the sorting effect.

[0009] As a further solution of the present utility model: The impurity removal assembly includes a screen, a telescopic spring, a receiving seat, and an impurity collection box. Among them, the screen is slidably connected inside the recycling bin. The bottom of the screen is connected to the telescopic spring. The lower end of the telescopic spring is connected to the receiving seat. The impurity collection box is slidably connected to the lower end inside the recycling bin. The screen screens the hardware buckle castings and impurities, so that the hardware buckle castings are intercepted and remain above the screen, and the impurities pass through the screen and fall into the impurity collection box below. The telescopic spring is used to make the screen shake up and down, improving the screening effect.

[0010] As a further solution of the present utility model: A cleaning brush is slidably connected to the upper surface of the screen. A connecting rod is provided at the upper end of the cleaning brush. The cleaning brush and the connecting rod can be used to clean the screen and prevent the screen from being blocked.

[0011] As a further solution of the present utility model: A positioning groove is provided at the bottom of the recycling bin. A positioning block is inserted between the bottom plate and the positioning groove. The insertion of the positioning block and the positioning groove can prevent the recycling bin from shifting.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] (1) Through the separation and sorting assembly of the present utility model, when the conveyor belt drives the main body of the hardware buckle casting to move under the cutting knife, the limiting motor drives the limiting screw to rotate. The rotation of the limiting screw drives the driving frame and the pressing plate to move downward, so that the pressing plate presses the hardware buckle castings on both sides. Then, the separation cylinder drives the cutting knife to move downward to cut the connection part of the hardware buckle castings on both sides, separating the hardware buckle castings on both sides. Then, the conveyor belt drives the hardware buckle castings on both sides to move. After the hardware buckle castings on both sides move to one end of the conveyor belt, they respectively fall into the two recycling bins below, and the partition plates prevent the hardware buckle castings on both sides from falling into the same-side recycling bin, thus completing the separation and sorting of the hardware buckle castings. The whole process does not require manual separation and sorting of the hardware buckle castings, shortening the time required for the separation and sorting of the hardware buckle castings, and thus improving the sorting and recycling efficiency of the hardware buckle castings.

[0014] (2) Through the impurity removal component of the present utility model, the die-castings of hardware fasteners that fall into the recycling bin land on the screen mesh. The impurities doped in the die-castings of hardware fasteners pass through the screen mesh and fall into the impurity collection box below, while the die-castings of hardware fasteners are intercepted and remain above the screen mesh. At the same time, the telescopic spring enables the screen mesh to shake up and down, improving the screening effect, and thus completing the removal of impurities. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, a sorting and recycling device for die-castings of hardware fasteners includes a frame 1. A conveyor belt 2 is arranged inside the frame 1. A number of die-casting bodies 3 of hardware fasteners are placed on the conveyor belt 2.

[0022] Among them, the separation and sorting component 4 includes a connecting frame 41, a separation cylinder 42, a cutting knife 43, a limit motor 44, a limit screw 45, a driving frame 46 and a pressing plate 48. Among them, a connecting frame 41 is provided at the upper end of one side of the frame 1, a separation cylinder 42 is provided at the bottom of the connecting frame 41, a cutting knife 43 is provided at the lower end of the separation cylinder 42, a limit screw 45 is provided at the upper end of the connecting frame 41, a limit motor 44 is provided at the upper end of the limit screw 45, a driving frame 46 is threadedly connected to the surface of the limit screw 45, and a pressing plate 48 is provided at the lower end of the driving frame 46. When the conveyor belt 2 drives the die-casting body 3 of the metal buckle to move below the cutting knife 43, the limit motor 44 drives the limit screw 45 to rotate, and the rotation of the limit screw 45 drives the driving frame 46 and the pressing plate 48 to move downward, so that the pressing plate 48 presses the die-castings of the metal buckles on both sides. Then, the separation cylinder 42 drives the cutting knife 43 to move downward to cut the connection part of the die-castings of the metal buckles on both sides, so that the die-castings of the metal buckles on both sides are separated. Then, the conveyor belt 2 drives the die-castings of the metal buckles on both sides to move. After the die-castings of the metal buckles on both sides move to one end of the conveyor belt 2, they respectively fall into the two recycling bins 5 below, and the partition plate 49 prevents the die-castings of the metal buckles on both sides from falling into the same recycling bin 5, thus completing the separation and sorting of the die-castings of the metal buckles. The whole process does not require manual separation and sorting of the die-castings of the metal buckles, shortening the time required for the separation and sorting of the die-castings of the metal buckles, and thus improving the efficiency of the sorting and recycling of the die-castings of the metal buckles.

[0023] A buffer spring 47 is connected between the driving frame 46 and the pressing plate 48, and a limit post is slidably connected between the buffer spring 47 and the driving frame 46. The buffer spring 47 and the limit post prevent the die-casting body 3 of the metal buckle from being deformed due to excessive pressure of the pressing plate 48.

[0024] Partition plates 49 are provided on the sides of the recycling bins 5 close to each other. The partition plates 49 separate the two recycling bins 5 to prevent different die-castings of the metal buckles from falling into the same recycling bin 5, improving the sorting effect.

[0025] The impurity removal component 7 includes a screen 71, a telescopic spring 72, a receiving seat 73 and an impurity collection box 74. Among them, a screen 71 is slidably connected inside the recycling bin 5, a telescopic spring 72 is connected to the bottom of the screen 71, the lower end of the telescopic spring 72 is connected to the receiving seat 73, and an impurity collection box 74 is slidably connected to the lower end inside the recycling bin 5. The screen 71 screens the die-castings of the metal buckles and impurities, so that the die-castings of the metal buckles are intercepted and remain above the screen 71, and the impurities pass through the screen 71 and fall into the impurity collection box 74 below, and the telescopic spring 72 is used to make the screen 71 shake up and down to improve the screening effect.

[0026] The upper end surface of the screen 71 is slidably connected with a cleaning brush 76. A connecting rod 77 is arranged at the upper end of the cleaning brush 76. The cleaning brush 76 and the connecting rod 77 can be used to clean the screen 71 and prevent the screen 71 from being blocked.

[0027] A positioning groove is arranged at the bottom of the recycling box 5. A positioning block 75 is inserted between the bottom plate 6 and the positioning groove. The insertion of the positioning block 75 and the positioning groove can prevent the recycling box 5 from shifting.

[0028] The working principle of the present utility model is as follows: First, a plurality of die-castings of hardware fasteners 3 are evenly placed on the conveyor belt 2. When the conveyor belt 2 drives the die-castings of hardware fasteners 3 to move below the cutting knife 43, then the limiting motor 44 drives the limiting screw 45 to rotate. The rotation of the limiting screw 45 drives the driving frame 46 and the pressing plate 48 to move downward, so that the pressing plate 48 presses the two sides of the die-castings of hardware fasteners. Then, the separating cylinder 42 drives the cutting knife 43 to move downward to cut the connection part of the two sides of the die-castings of hardware fasteners, so that the two sides of the die-castings of hardware fasteners are separated. Then, the conveyor belt 2 drives the two sides of the die-castings of hardware fasteners to move. After the two sides of the die-castings of hardware fasteners move to one end of the conveyor belt 2, they respectively fall into the two recycling boxes 5 below, and the partition plate 49 prevents the two sides of the die-castings of hardware fasteners from falling into the same recycling box 5, thus completing the separation and sorting of the die-castings of hardware fasteners. The whole process does not require manual separation and sorting of the die-castings of hardware fasteners, shortening the time required for the separation and sorting of the die-castings of hardware fasteners, and thus improving the sorting and recycling efficiency of the die-castings of hardware fasteners. The die-castings of hardware fasteners falling into the recycling box 5 land on the screen 71. The impurities mixed in the die-castings of hardware fasteners pass through the screen 71 and fall into the impurity collection box 74 below, while the die-castings of hardware fasteners are intercepted and remain above the screen 71. At the same time, the telescopic spring 72 enables the screen 71 to shake up and down, improving the screening effect, and thus completing the removal of impurities. The staff can clean the collected impurities by pulling the impurity collection box 74, and lift the recycling box 5 upward to make the recycling box 5 separate from the bottom plate 6, so as to recycle the die-castings of hardware fasteners collected in the recycling box 5.
