Description

Technical Field

[0001] The invention relates to equipment on a steel section production line, in particular to a belt feeding device for bundling steel sections. Background Art

[0002] At present, domestic steel production enterprises are equipped with steel stacking and bundling equipment in the finishing section to realize the factory packaging of profiles. Most bundling equipment uses 6-8mm wire balers. However, after the steel is bundled, the wire at the right angle of the steel is easy to break and damage the corners of the steel, and the bundling strength does not meet the requirements for bundling medium and large material stacks. The above bundling process has the problem of scratching the surface quality of the product or the bundling strength is not enough to break, which seriously affects the safety of the product logistics and the reliability of the packaging.

[0003] Therefore, many manufacturers give up the use of automatic strapping equipment and adopt the original manual strapping process without a suitable automatic strapping line as an alternative: after the steel section is stacked and formed, the stack is transported to the manual strapping station through the conveyor roller line. The steel strip with a thickness of 3-4mm, a width of 30-40mm and a material of Q235 is manually extracted from the reel storage device and wrapped around the steel section. After the ends of the strip are overlapped for a certain length, the strip is manually clamped and fixed, and the strap overlap joint is manually welded. Although this method of manually strapping steel strips can ensure the surface quality of the product, it has the following disadvantages: 1. The steel strip extracted from the reel storage device is in a bent state. When it is directly wrapped around the steel section, it cannot be completely fitted with the steel section, resulting in insufficient strapping strength. The steel section will become loose and even cause the steel strip to break, which seriously affects the safety of the product logistics and the reliability of the packaging; 2. When the operator extracts the steel strip, if the length of the steel strip needs to be determined, it needs to be prefabricated in advance, which increases the production cost of the strap and reduces work efficiency.

[0039] from Figure 7 , Figure 8 It can be seen that when the steel belt 2 reaches the clamping assembly 35, the clamping wheel hydraulic cylinder 351 retracts, and a certain gap is maintained between the belt-feeding clamping wheel 355 and the belt-feeding driving wheel 356 through the connecting shaft 352, the front and rear swing arms 353, and the eccentric shaft 354. After the steel belt smoothly reaches the belt-feeding driving wheel 356, the proportional control hydraulic motor 357 works, which drives the steel belt to move toward the outlet through the belt-feeding driving wheel 356 to reach the straightening assembly 34; Fig. 9 It can be seen that after the belt is threaded, the clamping wheel hydraulic cylinder 351 extends out, and through the connecting shaft 352, the front and rear swing arms 353, and the eccentric shaft 354, the belt feeding clamping wheel 355 presses the steel belt onto the belt feeding driving wheel 356 to prevent the steel belt from retracting.

[0040] Example 5

[0041] from Figure 1 , Figure 2 , Figure 3 , Figure 4It can be known that the belt feeding device for bundling steel sections of the present invention: the straightening assembly 34 includes a mounting plate 341, a connecting shaft 342, a moving block 343, an upper straightening adjustment wheel 344, a lower straightening wheel 345, and a connecting shaft 346; the mounting plate 341 is fixed on the top of the bracket 32, the moving block 343 is located inside the bracket 32, the upper end of the connecting shaft 342 is fixedly connected to the mounting plate 341, and the lower end is threadedly connected to the moving block 343, and the upper straightening adjustment wheel 344 is connected to the lower end of the moving block 343; the connecting shaft 346 is connected to the front and rear surfaces of the bracket 32, the lower straightening wheel 345 is sleeved on the middle section of the connecting shaft 346, and the upper straightening adjustment wheel 344 and the lower straightening wheel 345 are staggered left and right.

[0042] from Figure 1 , Figure 2 , Figure 3 , Figure 4 It can be seen that at least one of the upper straightening adjustment wheel 344 and the lower straightening wheel 345 is greater than one.

[0043] Since the steel strip is conveyed from the reel storage device, there will be bending. In order to ensure the quality of subsequent packaging and make the steel strip fit the surface of the steel section, the steel strip needs to be straightened: when the steel strip reaches the straightening assembly 34 through the clamping assembly 35, it is straightened by the upper straightening adjustment wheel 344 and the lower straightening wheel 345, ensuring that the steel strip fits the steel section completely, improving the bundling strength, and ensuring the safety of the product logistics and the reliability of the packaging. Among them, the upper and lower distances between the upper straightening adjustment wheel 344 and the lower straightening wheel 345 can be adjusted according to the thickness of the steel strip.

[0044] Example 6

[0045] from Figure 1 , Figure 2 , Figure 3 , Figure 4 It can be known that the belt feeding device for bundling steel sections of the present invention: the shearing assembly 38 is arranged on the right side of the bracket 32, and the shearing assembly 38 includes a machine base 380, a hydraulic shearing cylinder 381, a shearing blade 382, ​​a shearing knife seat 383, and a fixed-length measurement trigger sensor 384; the machine base 380 is fixed at the right exit of the bracket 32, the hydraulic shearing cylinder 381 is fixed on the top of the machine base 380, the shearing blade 382 is connected to the bottom of the hydraulic shearing cylinder 381, a steel belt channel is provided between the upper and lower knife seats of the shearing knife seat 383, and the fixed-length measurement trigger sensor 384 is arranged on the lower knife seat of the shearing knife seat 383 and is located to the right of the shearing blade 382.

[0046] When the steel belt is conveyed forward through the shearing knife seat 383, it contacts the fixed-length measurement trigger sensor 384 on the lower knife seat, which sends out a strap measurement pulse signal. The rotary encoder 376 starts counting, and the control system measures the length of the belt by the number of pulses of the encoder. When the belt reaches the set length for bundling steel sections, the hydraulic shear cylinder 381 receives the signal and extends out to cut the steel belt through the shearing blade 382 to obtain the fixed-length strap required for bundling steel sections.

[0047] Example 7

[0048] from Figure 1 , Figure 2 , Figure 3 , Figure 4 It can be seen that the belt feeding device for bundling steel sections of the present invention: the guide assembly 36 also includes side guide units at the left and right ends of the belt guide slot block 362, each side guide unit includes two front and rear side guide wheels 363, and the two side guide wheels 363 are fixed on the front and rear surfaces of the belt guide slot block 362.

[0049] The side guide wheel 363 guides the steel belt in the front-to-back direction when it enters from the left end of the bracket 32 ​​and exits from the guide groove block 362, ensuring that the steel belt is smoothly transported along the steel belt channel.

[0050] Example 8

[0051] from Figure 1 , Figure 2 , Figure 3 , Figure 4 It can be seen that the belt feeding device for bundling steel sections of the present invention: the shearing assembly 38 also includes two front and rear outlet pinch rollers 385, and the two outlet pinch rollers 385 are fixed on the lower knife seat of the shearing knife seat 383 and are arranged front and back.

[0052] The two exit pinch rollers 385 guide the front-to-back direction of the delivered steel strip to ensure that the steel strip is smoothly delivered to the steel strip bending mechanism.

[0053] Example 9

[0054] from Figure 1 , Figure 2 , Figure 3 , Figure 4 It can be seen that the belt feeding device for bundling steel sections of the present invention also includes a pushing component 33, which includes a hydraulic cylinder 331, a displacement sensor 332, and a linear guide rail 333. The hydraulic cylinder 331 and the linear guide rail 333 are both fixed on the base 31, and the displacement sensor 331 is arranged on the rod end of the hydraulic cylinder 331. The hydraulic cylinder 331 is connected to the left end of the bracket 32, and the slider at the lower part of the bracket 32 ​​is connected to the linear guide rail 333.

[0055] If the subsequent bundling of the belt feeding device is carried out by the bundling equipment, it is necessary to push the belt feeding device to the entrance of the bundling equipment and cut the steel belt at the entrance: when the steel belt reaches the bottom of the shear blade 382, ​​the feeding stops, and the hydraulic cylinder 331 works to push the bracket 32 ​​to move along the linear guide rail 333 to the entrance of the bundling equipment. At this time, the displacement sensor 332 controls the position of the belt feeding point through the displacement of the telescopic rod of the hydraulic cylinder 331. When the shearing assembly comes to the front end of the bundling equipment, the hydraulic cylinder 331 stops working. At this time, the steel belt 2 continues to be fed. When the steel belt is fed forward and passes through the shearing knife seat 383, it contacts the fixed-length measurement trigger sensor 384 on the lower knife seat, which sends a strap measurement pulse signal, and the rotary encoder 376 starts counting. The control system measures the length of the belt feeding through the pulse number of the encoder. When the belt feeding reaches the set length for bundling the steel section, the hydraulic shearing cylinder 381 receives the signal and extends through the shearing blade 382 to cut the steel belt to obtain the fixed-length strap required for bundling the steel section. When the baling equipment at the back is baling, the hydraulic cylinder 331 pulls the bracket 32 ​​back to the original position on the left. When the baling equipment has finished baling, the hydraulic cylinder 331 pushes the bracket 32 ​​to the front end of the baling equipment for a new round of shearing.

[0056] The working principle of the belt feeding device for bundling steel sections of the present invention is as follows: the steel belt extracted from the belt reel storage device passes through the guide component and the length measuring component to the clamping component, and the automatic belt feeding is realized by the clamping component. The steel belt is straightened by the straightening component and then smoothly reaches the shearing device: 1. If bundling is performed manually, the belt feeding continues. When the belt feeding length reaches the fixed length required for bundling steel sections, the steel belt is cut off to facilitate the subsequent bundling process; 2. If bundling is performed by bundling equipment, the pushing component works to position and move the base and the components thereon to the set feeding point, and then the belt feeding continues. When the belt feeding length reaches the fixed length required for bundling steel sections, the steel belt is cut off to facilitate the subsequent bundling process.

[0057] The advantages of the steel strip feeding device for bundling of the present invention are as follows: 1. Through the cooperation of the fixed-length measurement trigger sensor and the rotary encoder, the length of the cut steel strip is made to be the length required for the steel strip bundling, thereby realizing the fixed-length operation of the steel strip bundling length and improving the bundling work efficiency; 2. The movement of the steel strip feeding pressure wheel is driven by the clamping wheel hydraulic cylinder in the clamping assembly to realize the conveying and pressing of the steel strip to prevent it from retracting; 3. The bent steel strip extracted from the tape reel storage device is straightened by the straightening assembly, thereby ensuring the complete fit of the steel strip and the steel strip, improving the bundling strength, and ensuring the safety of the product logistics and the reliability of the packaging during transportation; 4. When bundling is subsequently performed by the bundling equipment, the shearing assembly is pushed to the front end of the bundling equipment by the pushing assembly and then cut, thereby facilitating the bundling of the bundling equipment; 5. The guide assembly, the length measuring assembly, the clamping assembly, the straightening assembly, and the shearing assembly form a conveying channel for the steel strip, and the smoothness of the channel improves the reliability and safety of the belt threading.

[0058] In summary, the present invention integrates steel strip clamping, automatic fixed-length strip feeding, straightening and shearing devices into one, and realizes the functions of automatic clamping of steel strips with a thickness greater than 3 mm, online measurement of strip feeding length, automatic straightening and leveling, and fixed-length shearing.
