Description

Technical Field

[0001] This invention relates to the field of steel bar baling machines, and specifically to a steel bar baling machine. Background Technology

[0002] Currently, steel coil packaging is a crucial protective measure for the storage and transportation of steel coils. Traditional steel coil packaging is a manual operation, which suffers from poor packaging quality, low production efficiency, and high labor intensity for workers. With the improvement of rolling technology, the inefficient manual extrusion packaging of steel coils simply cannot meet the requirements of mass production. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a steel bar baling machine that solves the shortcomings of existing inefficient manual extrusion steel coil packaging, which is fundamentally unable to meet the requirements of mass production.

[0004] The technical solution adopted in this invention is as follows: A steel bar baling machine includes: a base, a vertically arranged fixed plate at one end of the base, multiple vertical blocks at the top of the base, a plurality of drive push rods mounted on the fixed plate, a rotating assembly at the lower part of the fixed plate, the rotating assembly including a drive motor, a first gear mounted on the output shaft of the drive motor, a pair of parallel rotating shafts mounted on both sides of the fixed plate, a second gear mounted on the rotating shafts, a chain between the first gear and the second gear, a pair of opposing extrusion plates mounted on the base, the extrusion plates having a first through hole for easy insertion of the rotating shafts, the extrusion plates including a conical bottom, an upper end, and a connecting part, the connecting part connecting the conical bottom and the upper end, the extrusion plate at the end away from the fixed plate being fixed to the base, and the extrusion plate closer to the fixed plate being connected to the drive push rod, the drive push rod being used to push the extrusion plate closer to the fixed plate to move.

[0005] This invention drives a motor to rotate a first gear, which in turn drives a pair of second gears to rotate, thereby rotating a shaft. The rotation of the shaft causes the coiled steel bar bundle to rotate, and the drive push rod pushes one extrusion plate towards the other, thus extruding the steel bar bundle to achieve a predetermined thickness and facilitating wrapping with strapping tape. It is easy to operate and has high production efficiency.

[0006] Optionally, the top width of the tapered bottom is smaller.

[0007] Optionally, the upper end protrudes outward in the middle, such that the width of the middle part is greater than the width of its top and bottom.

[0008] Optionally, the working surface of the conical bottom is equipped with a first protrusion that slopes outward from the connecting portion, and the working surface of the upper end and the connecting portion is provided with a second protrusion that penetrates the upper end and the connecting portion. The top of the first protrusion is connected to the second protrusion, and the middle of the upper end is provided with a third protrusion that extends laterally outward, and the third protrusion is connected to the second protrusion. The first, second, and third protrusions of the present invention serve to assist in positioning the steel coil.

[0009] Optionally, the extrusion plate is provided with a strip groove extending downward from the upper surface of the upper end to the connecting portion, the strip groove penetrating both sides of the extrusion plate. The bandage of the present invention passes through the strip groove of the extrusion plate for convenient bandaging.

[0010] Optionally, the outer side of the conical bottom is provided with an outward protrusion, the outward protrusion is provided with a second through hole, a guide rod is installed in the second through hole, one end of the guide rod is connected to the fixing plate, and the other end is connected to the outward protrusion of the extrusion plate at the end away from the fixing plate.

[0011] Optionally, a slide rail is mounted on the bottom of the extrusion plate at the end furthest from the fixed plate. A slider is mounted on the slide rail, and multiple evenly distributed positioning holes are provided on the slide rail. By setting a slider and positioning holes on the slide rail, the slider in this invention serves to position the steel coil in conjunction with the extrusion plate, and also facilitates the operator's observation of the extrusion plate's position.

[0012] Optionally, the sidewall of the strip groove is provided with a sliding groove, and the upper and lower ends of the sliding groove are provided with elastic elements. The moving end of the elastic element is equipped with a floating block, the floating block is equipped with a telescopic cylinder, and the end of the telescopic cylinder is provided with a guide element.

[0013] Optionally, the working surface of the guide is an inclined surface; the outer edge of the slide groove is provided with a scale strip.

[0014] Optionally, the outer surfaces of the telescopic cylinder and guide are covered with outwardly arched flexible elements. In this invention, the ends of the wrapping strap bypass the flexible elements and are pre-tightened. The wrapping strap drives the telescopic cylinder, guide, and floating block to move along the groove, making the wrapping strap tightly adhere to the outer surface of the rolled steel strip. Then, the wrapping strap is further tightened by equipment or manual force. At this time, the wrapping strap pushes the flexible elements to deform and causes the guide to contract inward. Then, the wrapping strap is tightly bound to the steel strip. The floating block drives the telescopic cylinder and guide to rebound. By observing the maximum movement position of the flexible elements, it can be visually seen that the winding force and the elastic element of the telescopic cylinder are linearly related to the force used to tighten the wrapping strap.

[0015] Optionally, a return spring is provided inside the telescopic cylinder.

[0016] Beneficial effects 1. In this invention, the first gear of the drive motor rotates, which in turn drives a pair of second gears to rotate, thereby causing the shaft to rotate. The rotation of the shaft causes the coiled steel bar bundle to rotate, and the drive push rod pushes one of the extrusion plates to move towards the other extrusion plate, thus extruding the steel bar bundle for easy wrapping with strapping tape.

[0017] 2. By observing the maximum active position of the flexible component, it can be intuitively seen that the winding force and the tension of the telescopic cylinder's elastic component are linearly related to the force used to tighten the bandage. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] Example 1

[0023] The technical solution adopted in this invention is as follows: like Figure 1 and Figure 2 As shown, this invention discloses a steel bar baling machine, comprising: a base 1, a vertically arranged fixed plate 3 at one end of the base, multiple vertical blocks 2 at the top of the base, a plurality of drive push rods 4 mounted on the fixed plate, a rotating assembly 5 mounted on the lower part of the fixed plate, the rotating assembly including a drive motor 6, a first gear 7 mounted on the output shaft of the drive motor, a pair of parallel rotating shafts 8 mounted on both sides of the fixed plate, a second gear 9 mounted on the rotating shaft, a chain 10 mounted between the first gear and the second gear, a pair of opposing extrusion plates 11 mounted on the base, the extrusion plates having a first through hole 12 for easy insertion of the rotating shaft, the extrusion plates including a conical bottom 13, an upper end 14 and a connecting part 15, the connecting part connecting the conical bottom and the upper end, the extrusion plate at the end away from the fixed plate being fixed to the base, and the extrusion plate near the fixed plate being connected to the drive push rod, the drive push rod being used to push the extrusion plate near the fixed plate to move.

[0024] The top of the conical bottom is narrower. The middle of the upper end protrudes outward, making its width greater than that of its top and bottom. A first protrusion 16, inclined outward from the connecting portion, is mounted on the working surface of the conical bottom. A second protrusion 17, penetrating the upper end and connecting portion, is provided on the working surface of the upper end and connecting portion. The top of the first protrusion is connected to the second protrusion. A third protrusion 18, extending laterally outward, is provided in the middle of the upper end and is connected to the second protrusion.

[0025] The extrusion plate has a strip groove 19 extending downwards from the upper surface of its upper end to the connecting part, and the strip groove penetrates both sides of the extrusion plate. An outward protrusion 20 is mounted on the outer side of the conical bottom, and a second through hole 33 is provided on the outward protrusion. A guide rod 21 is installed in the second through hole. One end of the guide rod is connected to a fixing plate, and the other end is connected to the outward protrusion of the extrusion plate at the end away from the fixing plate. A slide rail 22 is mounted on the bottom of the extrusion plate at the end away from the fixing plate, and a slider 23 is mounted on the slide rail. The slide rail has a positioning hole 24.

[0026] Example 2

[0027] The difference between Example 2 and Example 1 is that, as Figure 3 , Figure 4 and Figure 5 As shown, the sidewall of the strip groove is provided with a sliding groove 25, and both the upper and lower ends of the sliding groove are provided with elastic elements 26. The moving end of the elastic element is equipped with a floating block 27, and the floating block is equipped with an elastic telescopic cylinder 28.

[0028] In this embodiment, the two ends of the wrapping tape are pre-tightened by passing around the flexible parts. The wrapping tape drives the telescopic cylinder, guide, and floating block to move along the slide groove, so that the wrapping tape is tightly attached to the outer surface of the rolled steel bar bundle. Then, the wrapping tape is further tightened by equipment or manpower. At this time, the wrapping tape pushes the flexible parts to deform and causes the guide to contract inward. Then the wrapping tape is tightly bound to the steel bar bundle. The floating block drives the telescopic cylinder and guide to rebound. The winding force can be intuitively seen by observing the maximum movement position of the flexible parts.
