Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of fastener processing, and more specifically, to a chain bucket type fastener lifting and feeding machine. Background Technology

[0002] In the fastener (such as bolts, nuts, and washers) production process, chain bucket elevators are key equipment for vertically conveying blanks or semi-finished products. Driven by a chain, the buckets circulate, transporting fasteners from lower hoppers to higher processing equipment (such as tapping machines and heat treatment furnaces). The stability of this conveying process and the cleanliness of the materials directly affect the accuracy of subsequent processing. With increasing demands for surface quality and conveying efficiency in fasteners, the shortcomings of traditional chain bucket elevators are becoming increasingly apparent: existing equipment generally lacks dust cleaning capabilities during the feeding process and cannot perform targeted cleaning of the rising buckets, leading to dust and impurity accumulation. This affects both fastener quality and the stability of equipment operation.

[0003] Traditional chain bucket elevators are designed solely for conveying, lacking dust removal and bucket cleaning modules. Fasteners are prone to accumulating metal shavings, dust, and other impurities during storage and transport. These impurities, after entering the elevator with the material, rise with the buckets and fall directly into subsequent processing equipment, causing them to embed in the threads or surface during processing, affecting the fastener assembly accuracy and service life. Simultaneously, during long-term operation, dust and fine material residue easily adhere to the inner wall of the buckets. Traditional equipment lacks an automatic cleaning structure; the accumulation of residue occupies bucket volume, reducing the single-batch conveying capacity, and may also cause newly conveyed fasteners to fall off due to vibration and contaminate them.

[0004] Therefore, the development of a chain bucket fastener lifting and feeding machine with dust cleaning and hopper self-cleaning functions has become an urgent need to ensure material cleanliness and conveying efficiency. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a chain bucket type fastener lifting and feeding machine, which solves the technical problem that existing equipment generally lacks a dust cleaning function during the feeding process.

[0006] According to one aspect, at least one embodiment of this disclosure provides a chain bucket type fastener lifting and feeding machine, comprising: The housing and the bottom bracket, wherein the bottom bracket is fixed to the bottom of the housing; The package includes a feed hopper, a discharge pipe, and a lifting assembly. The feed hopper is installed on the lower end of the side surface of the housing, the discharge pipe is installed on the upper end of the other side surface of the housing, and the lifting assembly is disposed in the housing. A dust collection assembly is installed on the discharge pipe; A slag removal and cleaning assembly is disposed at the bottom of the outer casing; The dust collection assembly includes an outer cover, which is fixed to the top of the discharge pipe and is connected to the inside of the discharge pipe. A barrier net is installed inside the outer cover, and a suction pipe is installed on the outer surface of the outer cover.

[0007] According to another aspect, in at least one embodiment of the present invention, the slag removal and cleaning assembly includes a slag discharge port, which is located at the bottom of the outer shell. A slag discharge pipe is provided at the bottom of the outer shell, and an opening is provided on the side surface of the outer shell. A movable cover connected by a horizontal linear drive is provided inside the opening.

[0008] As a further technical solution, a striking frame is rotatably connected inside the movable cover via a rotating shaft. A drive wheel that is electrically driven to rotate is provided on the inner wall of the movable cover. A driven wheel is provided at one end of the rotating shaft of the striking frame. The drive wheel and the driven wheel are connected by a belt drive.

[0009] According to another aspect, in at least one embodiment of the present invention, the lifting assembly includes a pair of rollers, which are rotatably connected to the top and bottom of the housing, respectively. One of the rollers is driven to rotate by electricity, and transmission grooves are provided at both ends of the surface of the roller.

[0010] As a further technical solution, an inner support frame is provided inside the outer shell, and a pair of stabilizing long grooves are opened on both sides of the inner support frame. A chain is connected in the transmission groove between the pair of shaft rollers.

[0011] As a further technical solution, all the chains are located in the stable long groove, and a number of lifting hoppers are connected between a pair of chains. The side end face of the lifting hopper slides and fits against the surface of the inner support frame.

[0012] As a further technical solution, a receiving plate is provided inside the discharge pipe, and the upper end of the receiving plate is inclined towards the inside of the outer shell.

[0013] As a further technical solution, the multiple striking heads of the striking frame all adopt a cylindrical structure.

[0014] The beneficial effects of the embodiments disclosed herein are as follows: In this disclosure, the dust collection component solves the problem of dust dispersion and environmental pollution during the feeding process through negative pressure suction and precise interception design.

[0017] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0018] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product.

In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0019] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0022] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] like Figures 1-4 As shown, it illustrates a chain bucket type fastener lifting and feeding machine according to an embodiment of the present disclosure, comprising: The outer casing 1 and the bottom bracket 2 are fixed to the bottom of the outer casing 1; The feeding hopper 3, the discharge pipe 4, and the lifting assembly 7 are provided. The feeding hopper 3 is installed on the lower end of one side surface of the outer shell 1, the discharge pipe 4 is installed on the upper end of the other side surface of the outer shell 1, and the lifting assembly 7 is disposed in the outer shell 1. Dust collection component 5, which is installed on the discharge pipe 4; A slag removal and cleaning component 6 is disposed at the bottom of the outer casing 1; The dust collection assembly 5 includes an outer cover 5-1, which is fixed to the top of the discharge pipe 4 and is connected to the inside of the discharge pipe 4. A barrier net 5-2 is installed inside the outer cover 5-1, and a suction pipe 5-3 is installed on the outer surface of the outer cover 5-1.

[0024] In some examples, in order to collect and purify dust during the fastener discharge process and prevent dust from escaping and polluting the working environment or affecting the health of operators, a dust collection component 5 is designed. This component includes an outer cover 5-1 at the top of the discharge pipe 4 that is connected to the inside of the pipe to form a closed space for dust collection. The barrier net 5-2 inside the outer cover 5-1 can intercept fastener particles in the suction airflow, preventing small fasteners from being sucked into the suction pipe 5-3 with the airflow, causing equipment blockage or material waste, and ensuring that only dust passes through the barrier net 5-2 to enter the subsequent processing stage.

[0025] The suction pipe 5-3 on the outer surface of the outer cover 5-1 can be connected to a negative pressure device. When the fastener is discharged through the discharge pipe 4, the negative pressure causes the dust raised in the pipe to be sucked into the outer cover 5-1. After being filtered by the barrier net 5-2, the clean airflow is discharged, while the dust is intercepted and collected.

[0026] The barrier net 5-2 effectively separates dust and particles, while the connection between the outer cover 5-1 and the discharge pipe 4 ensures thorough dust collection without any blind spots, preventing dust from escaping from the pipe port. This structure eliminates the need for additional manual dust cleaning, reducing labor intensity while meeting environmental protection production requirements.

[0027] During operation, the negative pressure equipment draws in air through the suction pipe 5-3, and the dust is collected after being filtered by the outer cover 5-1, allowing the fasteners to be discharged smoothly. The barrier filtration ensures precise separation, the negative pressure suction achieves efficient dust removal, and all components work together to complete the dust removal operation, meeting the requirements of clean production.

[0028] like Figures 1-4As shown in the figure, the slag removal assembly 6 proposed in this embodiment includes a slag removal port 6-1, which is located at the bottom of the outer shell 1. A slag removal pipe 6-2 is provided at the bottom of the outer shell 1. An opening 6-3 is provided on the side surface of the outer shell 1. A movable cover 6-4 is provided in the opening 6-3 and is connected by a horizontal linear drive. A striking frame 6-5 is rotatably connected inside the movable cover 6-4 via a rotating shaft. A drive wheel 6-6 is provided on the inner wall of the movable cover 6-4 and is driven by electricity. A driven wheel 6-7 is provided at one end of the rotating shaft of the striking frame 6-5. The drive wheel 6-6 and the driven wheel 6-7 are connected by a belt drive.

[0029] In some examples, in order to clean and collect the slag adhering to the surface of the lifting hopper 7-6 and avoid the slag accumulation affecting the feeding volume or entering subsequent processes with the fasteners and causing pollution, a slag cleaning and discharge component 6 is designed. This component includes a slag discharge port 6-1 at the bottom of the outer shell 1 connected to a slag discharge pipe 6-2, providing a discharge channel for the cleaned slag. The slag falls into the slag discharge pipe 6-2 through the slag discharge port 6-1 and can be collected and treated in a directional manner, avoiding it from scattering to the bottom of the outer shell 1 and being difficult to clean.

[0030] The movable cover 6-4 inside the opening 6-3 on the side surface of the outer shell 1 can reciprocate along the opening 6-3 through a horizontal linear drive, driving the internal striking frame 6-5 to adjust the striking position to ensure that different areas of the lifting hopper 7-6 can be covered; the drive wheel 6-6 on the inner wall of the movable cover 6-4 is connected to the driven wheel 6-7 on the rotating shaft of the striking frame 6-5 through a belt. The drive wheel 6-6 is driven by electricity to rotate, which can drive the striking frame 6-5 to rotate around the rotating shaft. When the striking frame 6-5 rotates, it collides and contacts the surface of the lifting hopper 7-6, shaking off the attached material residue.

[0031] The combination of horizontal linear drive and rotary impact allows the impact frame 6-5 to move laterally to expand the cleaning range and enhance the slag removal effect through continuous impact, avoiding incomplete cleaning due to excessively tight adhesion of slag.

[0032] The opening 6-3 provides a guide and installation space for the movable cover 6-4, ensuring its precise movement trajectory and avoiding interference with other structures of the outer shell 1; the belt drive structure can buffer the vibration generated by impact, protect the drive wheel 6-6 and the driven wheel 6-7, and extend the service life of the equipment.

[0033] During operation, the movable cover 6-4 moves the striking frame 6-5, and the drive wheel 6-6 rotates the striking frame 6-5 to strike the lifting hopper 7-6. After the material and slag are shaken off, they are discharged through the slag discharge pipe 6-2. The movable striking mechanism ensures thorough cleaning, and the directional slag discharge avoids contamination. All components work together to complete the cleaning and discharge of material and slag, meeting the needs of equipment maintenance.

[0034] like Figures 1-4As shown in the figure, the lifting assembly 7 in this embodiment includes a pair of rollers 7-1, which are rotatably connected to the top and bottom of the housing 1 respectively. One of the rollers 7-1 is driven to rotate by electricity. Both ends of the surface of the roller 7-1 are provided with transmission grooves 7-2. An inner support frame 7-3 is provided inside the housing 1. A pair of stabilizing long grooves 7-4 are provided on both sides of the inner support frame 7-3. A chain 7-5 is connected in the transmission groove 7-2 between the pair of rollers 7-1. The chains 7-5 are all located in the stabilizing long grooves 7-4. A plurality of lifting hoppers 7-6 are connected between the pair of chains 7-5. The side end face of the lifting hopper 7-6 is slidably attached to the surface of the inner support frame 7-3.

[0035] In some examples, in order to achieve continuous and stable lifting and feeding of fasteners and avoid problems such as jamming and feeding interruption in traditional feeding methods, a lifting component 7 is designed. This component includes top and bottom rollers 7-1 inside the housing 1 to provide support for the chain 7-5 drive. One of the rollers 7-1 is electrically driven to rotate, and the chain 7-5 is driven to circulate through the transmission grooves 7-2 at both ends of the surface of the roller 7-1. The closed-loop transmission structure of the chain 7-5 ensures that the feeding process is continuous and uninterrupted, without the need for frequent shutdowns for replenishment. The stabilizing grooves 7-4 on both sides of the inner support frame 7-3 inside the outer shell 1 provide sliding guidance for the chain 7-5. The chain 7-5 is located in the stabilizing grooves 7-4, which can limit its lateral displacement and prevent the chain 7-5 from shaking during movement, causing the lifting hopper 7-6 to tilt, thus ensuring the stability of feeding. The inner support frame 7-3 can also enhance the structural strength of the outer shell 1 and resist the tension generated by the transmission of the chain 7-5.

[0036] Several lifting buckets 7-6 connected between a pair of chains 7-5 are vertically lifted as the chains 7-5 move. The side end face of the lifting bucket 7-6 slides and fits against the surface of the inner support frame 7-3, further enhancing the stability of the lifting bucket 7-6 and preventing it from tipping over due to the shift in the center of gravity after fasteners are loaded.

[0037] The opening structure of the lifting hopper 7-6 is adapted to the feeding direction of the feeding hopper 3. After the fasteners fall from the feeding hopper 3 into the lifting hopper 7-6, they rise with the chain 7-5 to the top of the outer casing 1 and are discharged through the discharge pipe 4 under the action of gravity. The layout of the multi-lifting hopper 7-6 can increase the single feeding capacity. The design of the transmission groove 7-2 of the shaft roller 7-1 ensures a tight fit between the chain 7-5 and the shaft roller 7-1, avoiding slippage and affecting transmission efficiency.

[0038] During operation, the shaft roller 7-1 drives the chain 7-5 and the lifting hopper 7-6 to move. The lifting hopper 7-6 receives the fasteners and lifts them out. The chain 7-5 transmission ensures continuous feeding, the guiding structure ensures stable operation, and all components work together to achieve continuous and stable lifting and feeding of fasteners.

[0039] For example, such as Figure 4 As shown, a receiving plate 8 is provided inside the discharge pipe 4, and the upper end of the receiving plate 8 is inclined towards the inside of the outer shell 1.

[0040] In some examples, the receiving plate 8, which is inclined towards the inside of the outer casing 1 at the upper end of the material pipe, can accurately receive the fasteners that slide down from the lifting hopper 7-6. By using the inclination angle, the fasteners are guided to slide out of the pipe along a preset trajectory, avoiding the fasteners from directly hitting the inner wall of the pipe and generating dust or causing component wear.

[0041] For example, such as Figure 4 As shown, the multiple striking heads of the striking frame 6-5 all adopt a cylindrical structure.

[0042] In some examples, the multiple striking heads of the striking frame 6-5 adopt a cylindrical structure. When the arc surface of the striking head contacts the surface of the lifting hopper 7-6, it can disperse the impact force, which can both ensure that the attached material residue is shaken off and avoid the sharp structure from scratching or deforming the lifting hopper 7-6, thus extending the service life of the lifting hopper 7-6.

[0043] In actual use: The fasteners to be conveyed are poured into the feed hopper 3. The lifting assembly 7 is activated, and the electrically driven shaft roller 7-1 rotates. Through the transmission groove 7-2, it drives the chain 7-5 to circulate along the stable long groove 7-4 of the inner support frame 7-3. The lifting hopper 7-6 between the chains 7-5 rises with the chain 7-5, receiving the fasteners in the hopper and conveying them upwards. The side end face of the lifting hopper 7-6 slides against the inner support frame 7-3 to ensure stable conveying. After the fasteners rise to the top, they slide into the discharge pipe 4 through the inclined receiving plate 8. Simultaneously, the dust collection assembly 5 is activated, and the negative pressure equipment draws air through the suction pipe 5-3. The raised dust is sucked into the outer cover 5-1, and the blocking net 5-2 intercepts the fastener particles, thus collecting the dust. During the conveying interval, the slag removal and cleaning component 6 is activated. The horizontal linear drive moves the moving hood 6-4 along the opening 6-3. The drive wheel 6-6 drives the striking frame 6-5 to rotate via a belt, striking the lifting hopper 7-6 to shake off the attached slag. The slag is discharged through the slag discharge port 6-1 and the slag discharge pipe 6-2. The entire process achieves continuous feeding of fasteners, dust removal, and hopper self-cleaning in a seamless manner.
