Detailed Implementation

[0047] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed to enable those skilled in the art to better understand and implement the subject matter described herein. Changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0048] To better understand this utility model, the following is in conjunction with... Figures 1-16 This invention provides a detailed description of the dust removal and protection device for a complete production line of cold-rolled ribbed steel bars.

[0049] Example 1:

[0050] like Figures 1-4 As shown, the dust removal and protection device for the complete production line of cold-rolled ribbed steel bars includes: a protective house 100, the protective house 100 having an inner chamber 101 for accommodating processing equipment, the protective house 100 including a feed inlet 102 and a discharge outlet 103, and a dust collection component 200 connected to the inner chamber 101 on the protective house 100, the dust collection component 200 being connected to a dust collection box 300.

[0051] It should be noted that the processing equipment is used to process the plain round steel bars to form ribbed steel bars. During the steel bar processing, the oxide scale on the surface of the steel bars is removed to form oxide scale debris. Under the restriction of the protective house 100, even if the oxide scale debris splashes, it will be confined in the inner chamber 101. This facilitates the subsequent cleaning of the oxide scale debris and ensures that the oxide scale debris will not splash and injure people. Similarly, the scattered drawing powder is also confined in the inner chamber 101. The drawing powder scattered in the inner chamber 101 is sucked into the dust collection component 200. The exhaust port of the dust collection component 200 is connected to the dust collection box 300. The drawing powder and other dust debris sucked in by the dust collection component 200 are transported to the dust collection box 300 for collection and centralized treatment.

[0052] The protective house 100 is equipped with a wire feeding rack 510 for placing the round steel bars to be processed. Since the steel bars are placed on the wire feeding rack 510 in a wound manner, the steel bars will twist to a certain extent during the feeding process and store a certain amount of elastic potential energy. During the cold rolling process of the steel bars, the steel bars are prone to breakage. When the steel bars break, the elastic potential energy originally stored in the steel bars will be released rapidly. This sudden release of energy will cause the steel bars to vibrate or dance violently. The protective house 100 can play a good protective role, preventing the dancing steel bars from endangering the personal safety of employees. In addition, the protective house 100 can also play a certain role in sound insulation, reducing the harm of noise to employees.

[0053] In the embodiment, the feeding port 102 and the discharging port 103 are respectively arranged at the front end and the rear end of the protective house 100, a dust collecting bag (not shown in the figure) is arranged in the dust collecting box 300, the dust collecting bag wraps the exhaust pipe opening of the dust suction assembly 200 extending into the dust collecting box 300, the wire drawing powder and other dust scraps sucked by the dust suction assembly 200 all enter the dust collecting bag, the dust collecting bag can be taken out for cleaning, and a new dust collecting bag can be replaced, so that the cleaning is more convenient and fast.

[0054] By using the cold-rolled ribbed steel bar complete production line dust removal protection device, the protective house 100 can limit the wire drawing powder in the inner chamber 101, and the wire drawing powder and other dust in the inner chamber 101 are sucked into the dust collecting box 300 by the dust suction assembly 200 to be collected, so that the wire drawing powder and other dust do not pollute the workshop environment and harm the health of employees, the protective house 100 can also limit the scale scraps in the inner chamber 101, the scale scraps are convenient to clean, the protective house 100 has good protection effect, can prevent the scale scraps from splashing and injuring people or the broken steel bars from dancing and injuring people, guarantees the personal safety of employees, and the protective house 100 also has the sound insulation effect and reduces the harm of noise to employees.

Each capping unit 190 includes a sliding plate 191, a first handle 192, four wheel frames 193, four rollers 194 and two sealing strips 195. The first handle 192 and the four wheel frames 193 are fixedly installed on the bottom surface of the sliding plate 191. The four rollers 194 are rotatably installed on the four wheel frames 193, and each two rollers 194 are rollingly connected with one of the supporting members 180.

[0101] The processing equipment includes a phosphor removal machine 520, a drawing powder box 530, a rolling mill 540, and a drawing machine 550, which are sequentially arranged along the processing direction of the reinforcing steel bar. The reinforcing steel bar on the pay-off stand 510 passes through the inlet 102 into the inner chamber 101. First, the phosphor removal machine 520 removes the oxide skin on the surface of the reinforcing steel bar. Then, the reinforcing steel bar passes through the drawing powder box 530 in which the drawing powder is stored. In this process, the drawing powder adheres to the surface of the reinforcing steel bar to form a lubricating layer. Subsequently, the rolling mill 540 cold-rolls the reinforcing steel bar to form ribs on the surface of the round reinforcing steel bar to obtain the ribbed reinforcing steel bar. In this process, the drawing machine 550 provides the driving force for the forward movement of the reinforcing steel bar. Finally, the processed ribbed reinforcing steel bar passes out of the inner chamber 101 through the outlet 103 and is wound and collected in the take-up machine 560. By opening the door 150 to enter the shell 140, the roller of the phosphor removal machine 520 can be replaced, the drawing powder can be added, and the die blade of the rolling mill 540 can be replaced. The outlet area of the processing equipment is the area where the ribbed reinforcing steel bar starts to separate from the drawing machine 550.

[0102] The capping unit 190 is provided with three capping units 190, which are sequentially arranged along the processing direction of the reinforcing steel bar as the first capping unit 1901, the second capping unit 1902, and the third capping unit 1903. In the initial position, the three capping units 190 completely block the hoisting opening 106. The first capping unit 1901 corresponds to the position of the phosphor removal machine 520, the second capping unit 1902 corresponds to the position of the rolling mill 540, and the third capping unit 1903 corresponds to the position of the drawing machine 550.

[0103] For example, when the rolling mill 540 needs to be repaired, the first handle 192 of the second capping unit 1902 and the third capping unit 1903 is pulled to drive the second capping unit 1902 and the third capping unit 1903 to move towards the top plate 141, so that the third capping unit 1903 moves below the top plate 141, and the second capping unit 1902 moves to the initial position of the third capping unit 1903. At this time, the opening at the initial position of the second capping unit 1902 can be used to hoist the rolling mill 540 out for repair.
