[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0033] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0034] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0035] The utility model provides a step-feeding device for shearing ribbed steel bars, such as Figures 1 to 5 As shown, it includes a frame 1, which is slidably matched with a mounting frame 2, and the mounting frame 2 is linked with a driving mechanism 3. The driving mechanism 3 includes a driving wheel 31, and the driving wheel 31 is a cam structure. A linkage wheel 21 is provided on the side of the mounting frame 2 facing the driving mechanism 3. The driving wheel 31 is pressed against the linkage wheel 21 to drive the mounting frame 2 to slide up and down along the frame 1.

[0036] In this embodiment, a slide rail 17 is provided on the rack 1 , and a slider 23 is provided on the mounting frame 2 . The mounting frame 2 slides up and down vertically on the rack 1 through the sliding cooperation between the slider 23 and the slide rail 17 .

[0037] In this embodiment, the driving mechanism 3 also includes a driving member 32 and a driving shaft 33. The driving member 32 is linked to the driving shaft 33, and the driving wheel 31 is sleeved on the outer wall of the driving shaft 33. Based on the central axis of the driving shaft 33, the driving wheel 31 is an eccentric wheel structure and rotates around its own eccentric axis.

[0038] It should be noted that the eccentric wheel is a type of cam. In other embodiments, the driving wheel 31 can also be set to various cam structures such as elliptical and gourd-shaped, which can drive the linkage wheel 21 to produce a reciprocating motion effect of rising and falling.

[0039] In this embodiment, after the driving member 32 is started, power is transmitted to the driving shaft 33, causing the driving shaft 33 to start rotating. As the driving shaft 33 rotates, the driving wheel 31 of the eccentric wheel structure also starts to rotate. Due to the eccentric design of the driving wheel 31, its outer edge portion will produce periodic radial displacement relative to the central axis of the driving shaft 33 during the rotation process. When the driving wheel 31 rotates to a specific position, an upward thrust is applied to the linkage wheel 21 as it rotates, and the linkage wheel 21 transmits the received thrust to the mounting frame 2. Since the mounting frame 2 and the frame 1 are in a sliding fit, the mounting frame 2 will slide up and down along the frame 1 under the action of the thrust. As the driving shaft 33 continues to rotate and the driving wheel 31 and the linkage wheel 21 are periodically engaged, the mounting frame 2 will perform reciprocating lifting motion.

[0040] In this embodiment, the linkage wheel 21 is rotatably mounted on the mounting frame 2. The sidewall of the linkage wheel 21 is provided with an engaging groove 211. The drive wheel 31 engages and flexibly cooperates with the engaging groove 211, ensuring that power is smoothly transmitted from the drive wheel 31 to the linkage wheel 21, thereby driving the mounting frame 2 to slide along the frame 1. In this embodiment, the linkage wheel 21 is connected to the mounting frame 2 via a bearing, a bushing, or other rotational support device to ensure that it can freely rotate about its own axis. It should be noted that although the linkage wheel 21 can rotate, its position on the mounting frame 2 is fixed, that is, its axis remains relatively stationary with the mounting frame 2. When the mounting frame 2 slides along the frame 1, the linkage wheel 21 will also move accordingly, but its own axis will not change direction.

[0041] In this embodiment, a feeding piece 22 is fixedly connected to the mounting frame 2 , and as the mounting frame 2 performs reciprocating lifting motion, the feeding piece 22 is driven to perform reciprocating lifting motion.

[0042] In this embodiment, a material receiving member 11 is fixedly connected to the frame 1. The material receiving member 11 and the material feeding member 22 are both provided with a stepped surface 111. A plurality of receiving grooves 112 are provided on the stepped surface 111. The plurality of receiving grooves 112 are sequentially and side by side distributed along the stepped surface 111 from bottom to top. The receiving grooves 112 include receiving surfaces 1121 and limiting surfaces 1122 that are sequentially arranged and intersecting along the direction of steel bar transportation. Based on the material receiving member 11 and the material feeding member 22, the receiving surface 1121 is a downwardly inclined inclined structure. In the horizontal direction, the material receiving member 11 and the material feeding member 22 are parallel to each other and staggered. In this embodiment, the limiting surface 1122 is a vertical structure, and the receiving surface 1121 and the limiting surface 1122 intersect to form an acute angle structure.

[0043] It should be noted that the shape and structure of the feeding piece 22, the stepped surface 111 on the receiving piece 11, and the receiving groove 112 are the same. In the initial state, based on the horizontal direction, the height of the feeding piece 22 is lower than the height of the receiving piece 11. As the mounting frame 2 rises, the height of the feeding piece 22 is higher than or equal to the height of the receiving piece 11.

[0044] When the height of the feeding member 22 is higher than or equal to the height of the receiving member 11, the steel bar slides down along the receiving surface 1121 of the receiving groove 112 under the action of its gravity and reaches the intersection of the limit surface 1122 and the receiving surface 1121. Then the mounting frame 2 is lowered, and the feeding member 22 also drops back to the initial position, and the steel bar stays on the receiving groove 112 of the receiving member 11. The feeding member 22 can receive new steel bar, and so on. As the mounting frame 2 continues to rise and fall, the feeding member 22 lifts the steel bar to the receiving member 11, and continuously lifts the steel bar on the receiving member 11 to a higher step.

[0045] It should be noted that the width of the receiving surface 1121 needs to be greater than or equal to twice the width of the steel bar. In this embodiment, during the continued rise of the feeding member 22, the steel bar is guided by the receiving surface 1121 and restricted by the limiting surface 1122. The material receiving member 11 and the feeding member 22 are arranged in a staggered manner. The limiting surfaces 1122 of the receiving grooves 112 on the receiving member 11 are all located in the middle of the receiving surface 1121 in the receiving grooves 112 on the feeding member 22, so that When the mounting frame 2 is in the initial position and during the rising process, the steel bar is located in the middle of the receiving surface 1121 in the receiving groove 112 on the feeding piece 22. When the mounting frame 2 rises to the top, the limiting surface 1122 of the receiving groove 112 on the receiving piece 11 releases the limit on the steel bar, so that the steel bar can slide down under the action of gravity to the intersection of the limiting surface 1122 and the receiving surface 1121 in the receiving groove 112 on the receiving piece 11, and the steel bar is not affected when the mounting frame 2 descends.

[0046] In this embodiment, a coolant tank 34 is provided below the drive wheel 31. The coolant tank 34 is an open structure, and the opening of the coolant tank 34 corresponds to the drive wheel 31. During long-term operation or high-load conditions, the drive wheel 31 will generate a large amount of heat due to friction and other reasons, causing the temperature to rise. In this embodiment, the coolant in the coolant tank 34 is lubricating oil. The coolant tank 34 is open, and the drive wheel 31 picks up the lubricating oil as it rotates. The provision of the coolant tank 34 ensures that the lubricating oil can be replenished to its surface at any time as the drive wheel 31 rotates, promptly removing the heat generated by friction in the drive wheel 31, providing heat dissipation, cooling, and lubrication, thereby maintaining the drive wheel 31 within a suitable operating temperature range and preventing overheating damage. It can also effectively improve the lubrication effect of the eccentric wheel and its related components, reduce friction and wear, and enhance the stability of the entire conveying system.

[0047] In this embodiment, the device also includes a conveying mechanism 4 corresponding to the feeding member 22, the conveying mechanism 4 includes a transmission shaft 41, the outer wall of the transmission shaft 41 is sleeved with a driving gear 42, a rotatable driven gear is provided on the frame 1, and the outer walls of the driving gear 42 and the driven gear are sleeved with a conveying chain 43.

[0048] In this embodiment, the conveying mechanism 4 further includes a conveying motor 44 , the output end of the conveying motor 44 is provided with a power gear, the outer wall of the transmission shaft 41 is sleeved with a transmission gear 45 , and the outer walls of the power gear and the transmission gear 45 are sleeved with a transmission chain 46 .

[0049] In this embodiment, when the conveying motor 44 is started, the power gear begins to rotate. Through the transmission action of the transmission chain 46, the power gear transmits power to the transmission gear 45. The transmission gear 45 rotates accordingly, driving the transmission shaft 41 to rotate together. Because the transmission shaft 41 and the driving gear 42 are in a sleeve-type relationship, the rotation of the transmission shaft 41 drives the driving gear 42 to rotate together. The rotation of the driving gear 42 transmits power to the conveyor chain 43 through its meshing action with the conveyor chain 43. Driven by the driving gear 42 and the driven gear, the conveyor chain 43 forms a closed-loop transmission path and performs continuous circular motion along this path.

[0050] In this embodiment, the conveyor chain 43 and the feeding piece 22 are parallel to each other. The steel bars can be placed on the conveyor chain 43 and move forward with the movement of the conveyor chain 43, thereby achieving stable transportation of the steel bars toward the feeding piece 22.

[0051] In this embodiment, a loading switch 12, a full material switch 13, and a lack of material switch 14 are provided on the frame 1 on one side of the conveyor chain 43. The full material switch 13, the lack of material switch 14, and the loading switch 12 are distributed in sequence along the side facing the material receiving piece 11, and are used to detect the conveying status of the conveyor chain 43 to the feeding piece 22. The steel bars of the previous link are conveyed to the conveyor chain 43, and the conveyor chain 43 conveys the steel bars to the feeding piece 22. When the steel bars are conveyed to the loading switch 12, the feeding piece 22 lifts the steel bars up. After the steel bars touch the full material switch 13 for a certain period of time, the steel bars of the previous link stop conveying the steel bars to the conveyor chain 43 to prevent the steel bars from accumulating on the conveyor chain. When the lack of material switch 14 cannot detect the steel bars, the steel bars of the previous link continue to convey the steel bars to the conveyor chain 43.

[0052] In this embodiment, the device also includes a conveying mechanism 5, the top end face of the material receiving member 11 is an inclined surface 113 inclined toward one side of the conveying mechanism 5, and the conveying mechanism 5 includes a material dividing guide rail 51 and a material dividing conveying wheel 52. The material dividing guide rail 51 and the material dividing conveying wheel 52 are arranged side by side horizontally and alternately in sequence, and the material dividing guide rail 51 corresponds to the inclined surface 113.

[0053] In this embodiment, when the steel bars are lifted step by step to the top of the receiving piece 11 under the joint action of the feeding piece 22 and the receiving piece 11, since the top end face of the receiving piece 11 is an inclined surface 113 inclined toward the side of the conveying mechanism 5, the steel bars will naturally slide along this inclined surface 113 to the material dividing guide rail 51. Under the action of the material dividing conveying wheel 52, the steel bars can slide smoothly along the material dividing guide rail 51 and be guided to the next processing link.

[0054] In other embodiments, if the steel bars need to be further divided or classified, the dividing guide rail 51 can be designed to have a structure with different branches or paths.

[0055] In other embodiments, the material distribution and transfer wheel 52 may be driven by a motor, and the friction or mechanical force generated by its rotation may be used to further transfer the steel bars placed on the material distribution guide rail 51 to a designated position.

[0056] In this embodiment, a stop bar 53 is provided on the side of the conveying mechanism 5 away from the material receiving piece 11 , and the stop bar 53 includes several bars to ensure that the steel bars fall into the material dividing guide rail 51 .

[0057] In this embodiment, a material dividing start switch 15 is provided on one side of the inclined surface 113 on the frame 1, and a tail-off detection component 16 is provided on both ends of the conveying mechanism 5 on the frame 1. When the steel bars slide along the inclined surface 113 of the material receiving component 11, they will touch the material dividing start switch 15, and the steel bars falling into the material dividing guide rail 51 will be transported by the material dividing conveying wheel 52. The tail-off detection component 16 is used to detect whether there are steel bars at both ends of the conveying mechanism 5.

[0058] The utility model provides a stepped feeding device for shearing ribbed steel bars, which realizes an automatic, stable and step-by-step feeding process of the steel bars through a series of precise mechanical structures and power transmission mechanisms, and finally transports the steel bars to the next processing link.
