Description

Technical Field

[0001] The embodiments of this utility model relate to the field of shearing machine technology, specifically to a gantry-type fixed-length shearing machine for waste steel bars. Background Technology

[0002] Waste steel bars refer to steel reinforcement materials that are discarded during construction, demolition, or reconstruction due to construction, damage, or the expiration of their service life. Waste steel bars are usually composed of steel bar fragments, remnants, or old steel bars. After recycling, processing, and reuse, these waste steel bars can provide raw materials for the steel production industry, thereby reducing resource waste and minimizing environmental impact.

[0003] According to a public disclosure of a rebar cutting machine (publication number: CN207787572U), it includes a machine body with a shearing section. The machine body is equipped with a driving mechanism for driving the shearing section to cut rebar. A metering device is also provided on the machine body. The metering device includes a side plate, a slider, and a limiting part. The side plate is fixedly connected to the machine body, and the slider is slidably connected to the side plate. The limiting part restricts the slider's movement. However, the above device, through the interaction of components such as the side plate, slider, and limiting part, makes it difficult to effectively clean the dust generated during the cutting process. It is difficult to remove dust and debris generated during cutting, which not only reduces the comfort of the operating environment but also increases the impact of dust on the equipment, hindering work efficiency and reducing equipment failures. Therefore, improvements are needed. Utility Model Content

[0004] To overcome the above-mentioned defects, the present invention provides a gantry-type fixed-length shearing machine for waste steel bars, which solves the technical problem in related technologies / existing technologies that it is difficult to achieve the effect of cleaning the dust generated during the cutting process, and it is difficult to remove the dust and waste generated during the cutting process. This not only reduces the comfort of the operating environment, but also increases the impact of dust on the equipment, which is not conducive to improving work efficiency and reducing equipment failure.

[0005] According to one aspect, at least one embodiment of the present invention provides a gantry-type fixed-length shearing machine for waste steel bars, including a protective plate, wherein a conveyor belt is provided on the top of the protective plate;

[0006] A cleaning device is provided on the top of the protective plate. The cleaning device includes a fixing plate, which is fixedly connected to the side of the protective plate. A motor is fixedly connected to the side of the fixing plate. A reciprocating lead screw is fixedly connected to the output shaft of the motor. A threaded block is threaded to the circumferential surface of the reciprocating lead screw. A positioning plate is fixedly connected to the bottom of the threaded block. A rotating rod passes through the side of the positioning plate. A gear is fixedly connected to the circumferential surface of the rotating rod. A fan blade is fixedly connected to the circumferential surface of the rotating rod. A rack is fixedly connected to the top of the protective plate.

[0007] For example, in at least one embodiment of the present invention, a gantry-type fixed-length shearing machine for scrap steel bars is provided, which further includes the side of the gear meshing with the top of the rack, and the number of fan blades is set to several and arranged in a circumferential array on the circumferential surface of the rotating rod. Through the reciprocating motion of the fan blades, the dust and waste generated during the cutting process are effectively removed, and the area around the equipment is kept clean.

[0008] A limiting rod extends through the side of the threaded block, and one end of the limiting rod is fixedly connected to the side of the fixing plate. The design of the limiting rod effectively limits the threaded block and increases the stability of the device.

[0009] According to another aspect, at least one embodiment of the present invention also provides a gantry-type fixed-length shearing machine for waste steel bars, including a cleaning device comprising a feeding structure, the feeding structure comprising a rotating rod, the rotating rod being fixedly connected to one end of a reciprocating lead screw, a half gear being fixedly connected to the circumferential surface of the rotating rod, a support frame being fixedly connected to the top of the protective plate, a sliding plate being slidably connected to the side of the support frame, a support rod being fixedly connected to the side of the sliding plate, a toothed rod being fixedly connected to the bottom of the support rod, a protective shell being fixedly connected to the top of the sliding plate, a feeding pipe penetrating the bottom of the protective shell, a rotating shaft being rotatably connected to the bottom of the feeding pipe, a feeding plate being fixedly connected to the circumferential surface of the rotating shaft, and a limit plate being fixedly connected to the side of the support frame.

[0010] For example, in at least one embodiment of the present invention, a gantry-type fixed-length shearing machine for waste steel bars is provided, which further includes a torsion spring fixedly connected to the circumferential surface of the rotating shaft. The end of the torsion spring away from the rotating shaft is fixedly connected to the side of the feeding tube. The design of the torsion spring enables the feeding plate to open automatically when it moves away from the limiting plate, thereby realizing the function of automatic feeding.

[0011] A mounting plate is fixedly connected to the side of the support frame, and a spring is fixedly connected to the side of the mounting plate. The end of the spring away from the mounting plate is fixedly connected to the side of the rack.

[0012] The initial state of the spring is relaxed, and the initial state of the torsion spring is relaxed. The design of the torsion spring enables the feed plate to automatically reset, reducing manual intervention.

[0013] The toothed side of the half gear meshes with the bottom of the toothed rod. The limiting plate is located on the movement trajectory of the feeding plate.

[0014] The protective plate has a fixed-length cutting structure at its top, which includes a support plate. A drive module is located at the bottom of the support plate, and a cutting blade is located on the side of the drive module. A feeding rod is slidably connected to the top of the protective plate. The feeding rod is designed to automatically cut the scrap steel bars to a fixed length, avoiding manual operation and reducing possible pauses and unnecessary delays during the cutting process.

[0015] The support plate is L-shaped, and the feed rod is L-shaped. The design of the support plate can limit the movement of the scrap steel bars, thereby achieving the function of fixed-length cutting.

[0016] The beneficial effects of the embodiments of this utility model are as follows:

[0017] 1. In this utility model, the force of the reciprocating lead screw driven by the motor cooperates with the components such as the limiting rod, threaded block, and rotating rod in the cleaning device. This achieves the effect of displacing the rotating rod to drive the gear to move, so that the gear meshes with the rack and rotates. The rotation of the gear then drives the rotating rod to rotate, which in turn drives the fan blade to rotate. This achieves the effect of cleaning the dust generated during the cutting process, effectively removing dust and waste generated during the cutting process, keeping the area around the equipment clean, improving the comfort of the operating environment, reducing the impact of dust on the equipment, and helping to improve work efficiency and reduce equipment failure.

[0018] 2. In this utility model, the force of the reciprocating screw rotating to drive the rotating rod to rotate, in conjunction with the half gear, support frame, and feeding plate in the cleaning device, achieves the effect of the rotating shaft driving the feeding plate to reset through the elastic force of the torsion spring when the feeding plate moves away from the limiting plate. This causes the feeding port at the bottom of the feeding pipe to open, and the scrap steel bars inside the protective shell fall onto the conveyor belt through the feeding pipe. This achieves the effect of quantitative feeding, reduces possible pauses and unnecessary delays during the cutting process, and thus greatly improves production efficiency.

Detailed Implementation

[0027] The present invention 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 invention and not intended to limit its scope.

[0028] 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. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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 utility model based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] 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.

[0033] like Figures 1-6 As shown, it illustrates a gantry-type fixed-length shearing machine for waste steel bars in one embodiment of the present invention, including a protective plate 101, and a conveyor belt 102 is provided on the top of the protective plate 101;

[0034] A cleaning device 2 is provided on the top of the protective plate 101. The cleaning device 2 includes a fixing plate 201, which is fixedly connected to the side of the protective plate 101. A motor 202 is fixedly connected to the side of the fixing plate 201. A reciprocating lead screw 203 is fixedly connected to the output shaft of the motor 202. A threaded block 204 is threadedly connected to the circumferential surface of the reciprocating lead screw 203. A positioning plate 206 is fixedly connected to the bottom of the threaded block 204. A rotating rod 207 passes through the side of the positioning plate 206. A gear 208 is fixedly connected to the circumferential surface of the rotating rod 207. A fan blade 210 is fixedly connected to the circumferential surface of the rotating rod 207. A rack 209 is fixedly connected to the top of the protective plate 101.

[0035] In some examples, the side of gear 208 meshes with the top of rack 209, and the number of fan blades 210 is set to several and arranged in a circumferential array on the circumferential surface of rotating rod 207. Through the reciprocating motion of fan blades 210, dust and debris generated during the cutting process are effectively removed, keeping the area around the equipment clean.

[0036] A limiting rod 205 passes through the side of the threaded block 204. One end of the limiting rod 205 is fixedly connected to the side of the fixing plate 201. The design of the limiting rod 205 effectively limits the threaded block 204 and increases the stability of the device.

[0037] For example, such as Figures 1-6 As shown, this application uses a motor 202 to drive a reciprocating screw 203 to rotate, which in turn causes the threaded block 204 to move. The threaded block 204 is then limited by a limiting rod 205 on its side. The displacement of the threaded block 204 causes the positioning plate 206 to move, which in turn causes the rotating rod 207 to move. The displacement of the rotating rod 207 causes the gear 208 to move, so that the gear 208 meshes with the rack 209 and rotates. The rotation of the gear 208 then causes the rotating rod 207 to rotate, which in turn causes the fan blade 210 to rotate. This achieves the function of rotating the fan blade 210 during its reciprocating motion, thus cleaning the dust generated during the cutting process.

[0038] like Figures 1-6 As shown, this invention illustrates a gantry-type fixed-length shearing machine for waste steel bars in another embodiment of the present invention. The cleaning device 2 includes a feeding structure, which includes a rotating rod 211. The rotating rod 211 is fixedly connected to one end of a reciprocating screw 203. A half gear 212 is fixedly connected to the circumferential surface of the rotating rod 211. A support frame 213 is fixedly connected to the top of the protective plate 101. A sliding plate 215 is slidably connected to the side of the support frame 213. A support rod 217 is fixedly connected to the side of the sliding plate 215. A toothed rod 218 is fixedly connected to the bottom of the support rod 217. A protective shell 214 is fixedly connected to the top of the sliding plate 215. A feeding pipe 221 passes through the bottom of the protective shell 214. A rotating shaft 222 is rotatably connected to the bottom of the feeding pipe 221. A feeding plate 224 is fixedly connected to the circumferential surface of the rotating shaft 222. A limit plate 216 is fixedly connected to the side of the support frame 213.

[0039] In some examples, a torsion spring 223 is fixedly connected to the circumferential surface of the rotating shaft 222. The end of the torsion spring 223 away from the rotating shaft 222 is fixedly connected to the side of the feeding tube 221. The design of the torsion spring 223 enables the feeding plate 224 to open automatically when it moves away from the limiting plate 216, thus achieving the function of automatic feeding.

[0040] A mounting plate 220 is fixedly connected to the side of the support frame 213. A spring 219 is fixedly connected to the side of the mounting plate 220. The end of the spring 219 away from the mounting plate 220 is fixedly connected to the side of the rack 218. The design of the spring 219 enables the rack 209 to automatically reset, thus achieving the function of quantitative feeding.

[0041] The initial state of spring 219 is relaxed, and the initial state of torsion spring 223 is relaxed. The design of torsion spring 223 enables the feed plate 224 to automatically reset, reducing manual intervention.

[0042] The toothed side of the half gear 212 meshes with the bottom of the rack 218. The limiting plate 216 is located on the movement trajectory of the feeding plate 224. The limiting function of the feeding plate 224 and the reset function of the torsion spring 223 ensure the precise opening and closing of the feeding port, thereby realizing quantitative feeding.

[0043] The top of the protective plate 101 is provided with a fixed-length cutting structure, which includes a support plate 103. A drive module 104 is provided at the bottom of the support plate 103. The drive module 104 is located at the bottom of the support plate 103. A cutting blade 105 is provided on the side of the drive module 104. A feeding rod 106 is slidably connected to the top of the protective plate 101. The design of the feeding rod 106 can automatically complete the fixed-length cutting of waste steel bars, avoiding manual operation and reducing possible pauses and unnecessary delays during the cutting process.

[0044] The support plate 103 is L-shaped, and the cutting rod 106 is L-shaped. The design of the support plate 103 can limit the movement of the scrap steel bars, thereby achieving the function of fixed-length cutting.

[0045] For example, such as Figures 1-6As shown, the reciprocating screw 203 rotates, driving the rotating rod 211 to rotate. The rotating rod 211 then drives the half-gear 212 to rotate. When the toothed side of the half-gear 212 meshes with the rack 218, the rotation of the half-gear 212 causes the rack 218 to move. This movement of the rack 218 then causes the support rod 217 to move. The movement of the support rod 217 causes the sliding plate 215 to move. The movement of the sliding plate 215 then causes the protective shell 214 to move. The movement of the protective shell 214 causes the feed pipe 221 to move. The movement of the feed pipe 221 then causes the rotating shaft 222 to move. The movement of the rotating shaft 222 causes the feed plate 224 to move. When the feed plate 224 moves away from the limiting plate 216, the rotating shaft 222... The moving feed plate 224 is reset by the elastic force of the torsion spring 223, which opens the feed port at the bottom of the feed tube 221. The scrap steel bars inside the protective shell 214 fall onto the conveyor belt 102 through the feed tube 221. When the toothed side of the half gear 212 moves away from the toothed rod 218, the toothed rod 218 drives the support rod 217 to reset by the elastic force of the spring 219. Thus, the support rod 217 drives the slide plate 215 and the protective shell 214 to reset. The feed plate 224 is limited by the limiting plate 216 and rotates, thereby closing the feed port at the bottom of the feed tube 221, realizing the function of quantitative feeding. One end of the scrap steel bar is pressed against the side of the support plate 103 and cut by the cutting blade 105. After cutting, the feed rod 106 is pulled to feed the scrap steel bar, realizing the function of fixed-length cutting.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
