Description
Technical Field
[0001] This utility model relates to the field of rebar binding technology, and in particular to a rebar binding machine. Background Technology
[0002] A rebar binding machine is a mechanical device used on construction sites or other occasions where rebar needs to be bound. They are typically used to bind rebar or rebar mesh to ensure the rebar in a structure remains fixed and connected. Existing rebar binding machines generate debris during wire feeding due to friction between the wire feed drum and the wire. The accumulation of debris affects the feeding efficiency. Furthermore, some wire rolls are bent, making them prone to crossing or tangling during binding and wrapping, as illustrated in application number 201520815880.8, which describes a rebar binding machine. This device uses magnets to attract the iron filings generated when the wire passes through the meshing point of the wire guide gear, thus cleaning the iron filings and preventing their accumulation at the meshing point. However, when too many iron filings are attracted magnetically, the magnetic attraction weakens after the surface is covered with more filings, and the problem of iron filings accumulation remains unresolved with prolonged use.

The wire conveying box has two transmission wheels inside, with a transmission belt fitted between them. A motor is fixedly connected to one side of the inner wall of the wire conveying box, and the output end of the motor is fixedly connected to one side wall of one of the transmission wheels. A worm gear is fixedly connected to one side, and worm wheels mesh with both sides of the worm gear. A wire transfer roller is fixedly connected to the bottom end of each of the two worm wheels. A through groove is opened in the middle of the bottom end of the wire transfer box. A debris collection box is slidably connected to the bottom end of the wire transfer box. A magnetic suction plate is engaged with the inner wall of the bottom end of the debris collection box. A lead screw is fixedly connected to one side wall of another transmission wheel. A movable support is threaded to the middle of the lead screw. A U-shaped cleaning wiper is engaged with the bottom end of the movable support. A wire roll is provided inside the wire storage box.
[0008] The rebar binding machine is equipped with a straightening mechanism, which includes a sliding adjustment plate, a support plate, straightening wheels, a screw, a limiting plate, and a fixing plate. Multiple straightening wheels are rotatably connected to the top of the fixing plate and the top of the sliding adjustment plate, respectively. A fixing plate is fixedly connected to one side wall of the support plate, and a limiting plate is fixedly connected to one side wall of the sliding adjustment plate. A screw is threadedly connected to the limiting plate.
[0009] The other end of the worm gear is rotatably connected to the other side of the inner wall of the wire transfer box, and the bottom end of the wire transfer roller is rotatably connected to the inner wall of the bottom end of the wire transfer box.
[0010] A pull handle is fixedly connected to one side wall of the debris collection box, and the other side wall of the other drive wheel is rotatably connected to one side of the inner wall of the debris collection box.
[0011] The inner wall of the U-shaped cleaning blade is attached to the outer wall of the magnetic suction plate.

[0013] The bottom end of the support plate is fixedly connected to the inside of the rebar binding machine, the bottom end of the sliding adjustment plate is slidably connected to the inside of the rebar binding machine, and one end of the screw is rotatably connected to the inside of the fixed plate.
[0014] (3) Beneficial effects
[0015] The beneficial effects of this utility model are as follows: Through the straightening mechanism, when the wire rolls inside the rebar binding machine are used up, the user opens the wire replacement cover and places the unused wire rolls into the wire storage box. The user then rotates the screw, which drives the limiting plate to slide the sliding adjustment plate away from the support plate. One end of the wire roll is then placed between multiple straightening rollers. The screw is rotated to reset the sliding adjustment plate. At this point, one end of the wire roll is squeezed by the top of the support plate and the multiple straightening rollers at the top of the sliding adjustment plate. When one end of the wire roll is pulled, it passes between the multiple straightening rollers, straightening the wire roll. The straightened wire is easier to bind and wrap, and less prone to crossing or tangling. Combined with the wire conveying and cleaning mechanism, the user passes one end of the wire roll through the wire conveying drum and then inserts one end of the wire roll between two wire conveying rollers. The user then starts the motor, and the motor output... The worm gear rotates, driving two worm wheels to rotate. These worm wheels are positioned at the top of the wire feed roller to prevent iron powder or filings from accumulating during wire feeding. Excessive iron powder or filings falling onto the worm wheels would affect the wire feeding efficiency. When the wire feed roller rubs against the wire on the coil, the resulting debris passes through a slot and falls into a debris collection box. A magnetic plate inside the collection box attracts the debris. Combined with a drive wheel and belt, the motor output drives one drive wheel to rotate. This drive wheel, via the belt, causes another drive wheel to rotate, which in turn drives the lead screw, causing the moving support to reciprocate. The moving support then moves a U-shaped cleaning plate to scrape debris off the magnetic plate, preventing excessive accumulation and ensuring the magnetic plate can attract iron filings. Users can periodically pull the handle to remove the debris collection box and clean the debris inside. Attached Figure Description

A motor 604 is fixedly connected to one side of the inner wall of the wire conveying box 601. The output end of the motor 604 is fixedly connected to one side wall of one of the transmission wheels 605. A worm gear 613 is fixedly connected to one side of 605.

A through groove 609 is opened in the middle of the bottom end of the wire transfer box 601. A debris collection box 607 is slidably connected to the bottom end of the wire transfer box 601. A magnetic suction plate 606 is engaged with the inner wall of the bottom end of the debris collection box 607. A lead screw 614 is fixedly connected to one side wall of another transmission wheel 605. A movable support 612 is threadedly connected to the middle of the lead screw 614. A U-shaped cleaning wiper 611 is engaged with the bottom end of the movable support 612. A wire roll 4 is provided inside the wire storage box 3.
[0026] The rebar binding machine 1 has a straightening mechanism 5 inside. The straightening mechanism 5 includes a sliding adjustment plate 501, a support plate 502, a straightening wheel 503, a screw 504, a limiting plate 505, and a fixing plate 506. Multiple straightening wheels 503 are rotatably connected to the top of the fixing plate 506 and the top of the sliding adjustment plate 501, respectively. The fixing plate 506 is fixedly connected to one side wall of the support plate 502. The limiting plate 505 is fixedly connected to one side wall of the sliding adjustment plate 501. The screw 504 is threadedly connected to the limiting plate 505. In actual implementation, one end of the wire roll 4 is inserted between the two wire conveying rollers 610. The user then starts the motor 604. The output of the motor 604 drives the worm gear 613 to rotate, which in turn drives the two worm wheels 602 to rotate. The worm wheels 602 are located at the top of the wire conveying rollers 610 to prevent iron powder or iron filings from being generated during wire feeding due to friction between the wire and the wire conveying rollers 610.

To prevent excessive accumulation of wire scrap on the magnetic suction plate 606, which would hinder its ability to attract iron filings, the user can periodically pull out the scrap collection box 607 by pulling out the handle 608 to remove the scrap. When the wire coil 4 inside the rebar binding machine 1 is used up, the user opens the wire replacement cover 2 and places the unused wire coil 4 into the wire storage box 3. Then, the user rotates the screw 504, which drives the limiting plate 505 to slide the sliding adjustment plate 501 away from the support plate 502. Finally, one end of the wire coil 4 is placed into multiple... Between the leveling wheels 503, the screw 504 is rotated to reset the sliding adjustment plate 501. At this time, one end of the wire coil 4 is squeezed by the top of the support plate 502 and the multiple leveling wheels 503 at the top of the sliding adjustment plate 501. When one end of the wire coil 4 is pulled, the wire coil 4 passes between the multiple leveling wheels 503, which will straighten the wire coil 4. The leveled wire is easier to bind and wrap, and it is less likely to cross or tangle. Then the user operates the rebar binding machine 1 to bind the rebar. It should be noted that the user's use of the rebar binding machine 1 to bind the rebar is based on existing technology.
