[0041] Compared with the prior art, the beneficial effects of the hollow anchor bolt production line system disclosed in this invention are as follows.

[0042] 1. The production line system provided by this invention realizes the automatic connection of processes such as hollow anchor bolt feeding, thread rolling, cutting, marking, and bundling, without the need for manual intervention, thereby effectively improving production efficiency and reducing labor costs.

[0043] 2. The production system provided by this invention allows for modular combinations of processes such as feeding, thread rolling, cutting, marking, and bundling, based on actual site and capacity requirements. Building upon the single-process assembly line operation of feeding, thread rolling, cutting, marking, and bundling, a "general-specific-general" production process can be expanded. Specifically, before thread rolling of the hollow anchor rods, the hollow anchor rods are divided into two rows for thread rolling using two thread rolling machines. After thread rolling, the two rows are merged into one for unified cutting and marking, effectively compensating for the low processing efficiency of thread rolling machines, thereby significantly improving production efficiency and reducing the floor space required for the production line.

[0044] 3. Compared with the manual feeding method in the prior art, the production method provided by the present invention uses a magnetic attraction mechanism to automatically attract and separate a row of raw materials from bundles, avoiding manual feeding. In addition, the raw material feeding device separates the raw materials arranged on the feeding rack into individual pieces and guides them onto the roller table, thereby realizing automatic feeding.

[0045] 4. The feeding and discharging speeds can be controlled by adjusting the conveying speed of the relevant rolling tables; the heating temperature of the material and the temperature after rolling can be monitored by setting a temperature monitoring device near the rolling machine; the performance of the hollow anchor rod after rolling can be controlled by controlling the material conveying speed and heating temperature.

[0046] 5. Compared with manual bundling, the present invention can automatically bundle hollow anchor rods into hexagons by reasonably configuring the bundling device, thereby improving bundling efficiency and bundling tightness.

[0047] 6. Other key advantages of the present invention are described directly and implicitly in the detailed embodiments described below.

[0065] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0066] like Figure 1As shown, an embodiment of the present invention discloses a production line system for hollow anchor bolts 100. The system includes: a raw material temporary storage device 11, a raw material feeding device 12, a raw material conveying device 20, a material separating device 30, a thread rolling device 40, a material combining device 50, a length-cutting device 60, a finished product guiding device 70, a bundling device 80, and a finished product storage device 90.

[0067] The raw material conveying device 20, the material separating device 30, the wire rolling device 40, the material combining device 50, and the fixed-length cutting device 60 are arranged linearly in sequence along the conveying direction; the raw material temporary storage device 11 is located on the side of the raw material conveying device 20, and the raw material feeding device 12 is located between the raw material temporary storage device 11 and the raw material conveying device 20; the bundling device 80 is located on the side of the fixed-length cutting device 60, and the finished product guiding device 70 is located between the bundling device 80 and the fixed-length cutting device 60; the finished product storage device 90 is located downstream of the bundling device 80.

[0068] The raw material storage device 11 is used to store the hollow anchor rods 100 to be threaded and cut; the raw material feeding device 12 is used to move the hollow anchor rods 100 on the raw material storage device 11 laterally to the raw material conveying device 20, and the raw material conveying device 20 is used to convey the hollow anchor rods 100 toward the distribution device 30; the distribution device 30 is used to receive the hollow anchor rods 100 from the raw material conveying device 20, and to distribute the received hollow anchor rods 100 laterally to both sides to form two rows, and to convey the two rows of hollow anchor rods 100 toward the threading device 40; the threading device 40 includes two threading machines 41 respectively opposite to the two rows of hollow anchor rods 100, and the two threading machines 41 respectively support the two rows of hollow anchor rods 100 and perform threading on the hollow anchor rods 100. The material combining device 50 is used to receive two rows of hollow anchor rods 100 processed by the thread rolling machine 41, and to move the two rows of hollow anchor rods 100 laterally towards the middle to merge them into one row, and to move the hollow anchor rods 100 toward the length cutting device 60; the length cutting device 60 is used to receive the hollow anchor rods 100 from the material combining device 50 and to cut the received hollow anchor rods 100 to a fixed length; the finished product guiding device 70 is used to move the hollow anchor rods 100 laterally to the side of the length cutting device 60; the bundling device 80 is used to receive the hollow anchor rods 100 on the finished product guiding device 70 and to stack the received hollow anchor rods 100, and then bundle them; the finished product storage device 90 is used to receive and store the bundled hollow anchor rods 100 from the bundling device 80.

[0069] The composition and specific working process of each device are described below.

[0070] like Figure 2 and combined Figure 1As shown, the raw material storage device 11 has multiple horizontally arranged material level bins 111. The hollow anchor rods 100 to be processed are placed in the material level bins 111 in a layered arrangement. Above the material level bins 111 is a first magnetic attraction mechanism 112. The first magnetic attraction mechanism 112 uses magnetic force to grab one layer (multiple) of hollow anchor rods 100 at a time, and places the hollow anchor rods 100 at the raw material feeding device 12 by horizontal movement.

[0071] like Figure 2 , 3 and combined Figure 1 As shown, the raw material conveying device 20 includes a raw material conveying roller table 21 and a lifting guide device 22. The raw material loading device is located on the side of the raw material conveying roller table 21. The raw material loading device includes a raw material loading rack 121 that can be pivoted so that the end away from the raw material conveying roller table 21 is tilted upwards. A first stop limiting mechanism 122 and a first material distribution mechanism 123 are provided on the raw material loading rack 121. The first magnetic attraction mechanism 112 moves the grabbed hollow anchor rods 100 laterally and places them flat on the raw material loading rack 121. After the hollow anchor rods 100 are placed on the raw material loading rack 121, the raw material loading rack 121 tilts towards the raw material conveying roller table 21. At this time, the hollow anchor rods 100 move laterally towards the raw material conveying roller table under the action of gravity. Following the trend, the first stop limiting mechanism 122 stops the hollow anchor rod 100, and the lifting guide device 22 rises to guide the material. By controlling the periodic operation of the first material distribution mechanism 123, the first stop limiting mechanism 122 releases the frontmost hollow anchor rod 100 one by one and then limits the remaining hollow anchor rods 100 on the raw material feeding rack 121 again, thereby controlling the hollow anchor rods 100 on the raw material feeding rack 121 to move laterally to the raw material conveying roller table 21. Then, the lifting guide device 22 lowers the raw material conveying roller table 21 to convey the hollow anchor rods 100 towards the material distribution device 30.

[0072] like Figure 4 and combined Figure 1As shown, the material distribution device 30 includes a central material distribution roller 31, a material distribution frame 33, and side receiving rollers 32. The central material distribution roller 31 corresponds to the aforementioned raw material conveying roller 21 and is used to receive the hollow anchor rods 100 from the raw material conveying roller 21. Two material distribution frames 33 are located on either side of the central material distribution roller 31, and both frames are inclined outwards, forming a ridge-like shape with a high center and low sides. Two side receiving rollers 32 are located on the outer sides of the two material distribution frames 33. A first bidirectional turning mechanism 311 is installed on the central material distribution roller 31. The hollow anchor rods 100 on the central material distribution roller table 31 are distributed to the material distribution racks 33 on both sides. Each material distribution rack 33 is equipped with a second stop limiting mechanism 331 and a second material distribution mechanism 332. The second stop limiting mechanism 331 is used to limit the multiple flat hollow anchor rods 100 distributed to the material distribution rack 33, so that the material distribution rack 33 has the ability to temporarily store the hollow anchor rods 100. The second stop limiting mechanism 331 and the second material distribution mechanism 332 have similar structures and working principles to the first stop limiting mechanism 122 and the first material distribution mechanism 123. That is, under the gravity of the hollow anchor rods 100, the second material distribution mechanism 332 can release the hollow anchor rods 100 one by one through periodic actions and move them laterally to the side receiving roller table 32. The side receiving roller tables 32 on both sides are used to receive the hollow anchor rods 100 from the material distribution frame 33 and transport them towards the thread rolling device 40. The side receiving roller tables 32 are equipped with multiple sets of cam mechanisms 321. By rotating the cam mechanisms through the power system, the roller tables can be raised and lowered as a whole, thereby achieving fixed-center height reception of hollow anchor rods 100 of different diameters. In this way, the hollow anchor rods 100 are divided into two rows and transported towards the thread rolling device 40 respectively. When passing through the thread rolling device 40, the two rows of hollow anchor rods 100 are processed by the thread rolling machine 41. The second material distribution mechanism 332 controls the lateral movement of the hollow anchor rods 100 on the material distribution frame 33 to the side receiving roller tables 32 based on the processing speed of the thread rolling machine 41, so that the thread rolling machine 41 can continuously process the hollow anchor rods 100 without causing the hollow anchor rods 100 to stagnate on the side receiving roller tables 32.

[0073] like Figure 5 and combined Figure 1 As shown, the thread rolling device 40 includes two thread rolling machines 41, which correspond to the two side receiving roller tables 32 of the material distribution device 30. Driven by the side receiving roller tables 32, the two rows of hollow anchor rods 100 pass through the two thread rolling machines 41 respectively, thereby completing the thread rolling process of the hollow anchor rods 100. Preferably, a heating device 42 is provided upstream of each thread rolling machine 41 to heat the hollow anchor rods 100, thereby improving the thread rolling effect and efficiency.

[0074] like Figure 6 and combined Figure 1 As shown, the material mixing device 50 includes: a side material mixing roller 51, a material mixing frame 53, and a central receiving roller 52; the side material mixing roller 51 includes two, each corresponding to one of the two thread rolling machines 41 of the thread rolling device 40, and each side material mixing roller 51 is used to receive hollow anchor rods 100 from the two thread rolling machines 41; the material mixing frame 53 includes two, each located inside the two side material mixing rollers 51, and the central receiving roller 52 is located between the two material mixing frames 53, and both material mixing frames 53 are inclined towards the central receiving roller 52. Each material mixing frame 53 is equipped with a third stop limiting mechanism 531 and a third material distributing mechanism 52. 32. The third stop limiting mechanism 531 and the third material distribution mechanism 532 are similar in structure and function to the first limiting stop mechanism, the first material distribution mechanism, the second limiting stop mechanism, and the second material distribution mechanism mentioned above. Each side material gathering roller 51 is provided with a first one-way material turning mechanism 511. The first one-way material turning mechanism 511 is used to move the hollow anchor rods 100 on the side material gathering roller 51 one by one to the material gathering frame 53. Under the action of gravity and the tilting action of the material gathering frame 53, the hollow anchor rods 100 move laterally towards the center and are laid flat on the material gathering frame 53 one by one. Therefore, the third stop limiting mechanism 531 enables the material gathering frame 53 to temporarily store the hollow anchor rods 100. The third material distribution mechanism 532 causes the hollow anchor rods 100 on the material collection frame 53 to move laterally one by one to the central receiving roller 52 through periodic operation. In this way, two rows of hollow anchor rods 100 are combined into one row, and the central receiving roller 52 receives the hollow anchor rods 100 and transports them toward the fixed length cutting device 60.

[0075] like Figure 7 , 8 and combined Figure 1As shown, the length-limiting cutting device 60 includes a sawing machine 61 and a sawing roller 63. A length-limiting mechanism 64 is provided between adjacent rollers of the sawing roller 63. This length-limiting mechanism 64 moves upward to stop the end of the hollow anchor rod 100. The middle receiving roller 52 of the aforementioned material-gathering device 50 allows the hollow anchor rod 100 to enter the sawing roller 63 after passing through the sawing machine 61. According to the preset size, the corresponding length-limiting mechanism 64 moves upward to stop the end of the hollow anchor rod 100, thereby limiting the cutting size. Subsequently, the sawing machine 61 cuts the rod. Preferably, multiple length-limiting mechanisms 64 are arranged at intervals and can be moved by servo drive, thereby enabling the calibration and cutting of multiple lengths. A second bidirectional turning mechanism 65 is also installed on the sawing roller 63. This second bidirectional turning mechanism 65 is used to selectively distribute the cut hollow anchor rods 100 to both sides. For example, hollow anchor rods 100 of the same length are distributed to one side of the finished product guide device 70, and hollow anchor rods 100 of different lengths are distributed to the opposite side. Preferably, a marking machine 62 is also provided at the sawing machine 61 for marking and numbering the cut hollow anchor rods 100.

[0076] like Figure 8 , 9 and combined Figure 1 As shown, the finished product guiding device 70 includes a finished product guiding frame 71, which has an inclined portion 711 and a horizontal portion 712. Hollow anchor rods 100, distributed by the second bidirectional turning mechanism 65 on the sawing roller table 63, are moved laterally to the inclined portion 711 and temporarily stored thereby by a fourth stop limiting mechanism 72 at the inclined portion 711. While the hollow anchor rods 100 are temporarily stored in the inclined portion 711, an aligning mechanism 73, located at the axial end and including a cylinder and a push plate connected to the cylinder, aligns the hollow anchor rods 100 by driving the push plate to push against the end of the hollow anchor rods 100. After the hollow anchor rods 100 are aligned, the fourth stop limiting mechanism 72 releases the hollow anchor rods 100, causing them to move laterally to the horizontal portion 712. The pushing mechanism 74 is located on the horizontal part 712. After the hollow anchor rod 100 moves laterally to the horizontal part 712, the pushing mechanism 74 pushes the arranged hollow anchor rods 100 laterally by driving them to eliminate the gaps between the hollow anchor rods 100.

[0077] like Figure 7 , 10 and combined Figure 1As shown, the bundling device 80 includes: a bundling auxiliary roller table 82 disposed on the side of the finished product guide device 70, a second magnetic suction mechanism 81 spanning across the bundling auxiliary roller table 82, an automatic bundling machine 83 disposed at the bundling auxiliary roller table 82, and a bundling conveying roller table 84 located downstream of the automatic bundling machine. The second magnetic suction mechanism 81 grabs the hollow anchor rods 100 laid flat on the horizontal part 712 of the finished product guide frame 71 to the bundling auxiliary roller table 82 by lateral movement. After multiple grabbing, the hollow anchor rods 100 are formed into multiple layers. Multiple sets of adjustable shaping mechanisms 821 are arranged on the bundling auxiliary roller table 82, which can constrain the shape of the multiple layers of hollow anchor rods 100 to form a polygonal structure. The automatic bundling machine 81 performs the first bundling of the hollow anchor rods 100 forming the polygonal structure. Subsequently, the bundling auxiliary roller table 82 conveys them forward at a set distance, and the automatic bundling machine 83 performs the second bundling. The above method can be used for multi-segment bundling. After bundling is completed, the bundling conveyor roller 84 transports the bundled hollow anchor rods 100 to the finished product storage device 90.

[0078] like Figure 11 and combined Figure 1 As shown, the finished product storage device 90 includes a bundling distribution roller table 91 and a finished product storage rack 93. The bundling distribution roller table 91 is used to receive bundles of hollow anchor rods 100 from the bundling device 80.
