Description

Technical Field

[0001] This utility model relates to equipment on a steel production line, and more particularly to a belt feeding device for bundling steel sections. Background Technology

[0002] Currently, domestic steel profile manufacturers all have steel profile stacking and bundling equipment in their finishing stages to achieve finished product packaging. Most bundling equipment uses 6-8mm wire balers. However, after bundling, the wire at the right angles of the steel profiles is prone to breakage and damage to the edges, and the bundling strength does not meet the requirements for bundling medium to large-sized stacks. The above bundling process suffers from scratches on the product surface or insufficient bundling strength leading to breakage, seriously affecting the safety and reliability of product transportation and packaging.

[0003] Therefore, many manufacturers have abandoned the use of automated bundling equipment and, in the absence of suitable automated bundling lines, have adopted the primitive manual bundling process: after the steel sections are stacked, the stacks are transported to the manual bundling station via a conveyor roller conveyor. Workers manually extract steel strips (3-4mm thick, 30-40mm wide, Q235 material) from the strip storage device, wrap them around the steel section, overlap the ends by a certain length, and then manually clamp and fix the ends, manually welding the overlap joints. While this manual bundling method can ensure the surface quality of the product, it has the following disadvantages: 1. The steel strips extracted from the strip storage device are in a bent state, and when manually wrapped around the steel section, they cannot fully adhere to the steel, resulting in insufficient bundling strength. The steel section may loosen, or even the steel strip may break, seriously affecting the safety of product logistics and the reliability of packaging; 2. When workers extract the steel strips, the length of the strips needs to be pre-made, increasing the production cost of the bundling and reducing work efficiency. Utility Model Content

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Example 1

[0028] from Figure 1 , Figure 2 , Figure 3 , Figure 4 As can be seen, the present utility model of a steel bundling feeding device includes a base 31, a bracket 32, a straightening component 34, a guiding component 36, a length measuring component 37, a shearing component 38, and a clamping component 35; the bracket 32 ​​is set on the base 31, and the guiding component 36, the length measuring component 37, the clamping component 35, the straightening component 34, and the shearing component 38 are arranged from left to right and are all connected to the bracket 32.

[0029] from Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5It can be seen that after the steel strip 2 is manually extracted from the reel storage device 1, it is sent to the clamping assembly 35 through the guide component 36 and length measuring component 37 of the steel bundling feeding device 3. The clamping assembly 35 then drives the steel strip through the straightening assembly 34 to the shearing assembly 38 and continues to feed it forward. When the length measuring component 37 determines that the length of the steel strip sent out from the shearing assembly 38 has reached the length for bundling the steel, the shearing assembly 38 cuts the steel strip. The cut steel strip is then used by the workers or bundling equipment to bundle the steel. Example 2

[0030] from Figure 1 , Figure 2 , Figure 3 , Figure 4 As can be seen, the present invention relates to a steel strip feeding device for bundling: a guide assembly 36 is installed inside a support 32, the guide assembly 36 includes two guide wheels 361 (upper and lower) and two guide strip grooves 362 (front and rear); the two guide wheels 361 are connected above and below the steel strip inlet at the left end of the support 32, the two guide strip grooves 362 are fixed on the front and rear surfaces of the support 32 and located to the right of the two guide wheels 361, and the inner surfaces of the two guide strip grooves 362 are provided with opening grooves, the front and rear opening grooves forming a steel strip guiding channel.

[0031] After the steel strip 2 is manually extracted from the reel storage device 1, it is inserted into the feeding device 3, so that the steel strip 2 passes through the middle of the upper and lower guide wheels 361 at the left end of the bracket 32, and reaches the length measuring component 37 after passing through the steel strip guide channel between the two guide groove blocks 362. Example 3

[0032] from Figure 1 , Figure 2 , Figure 3 , Figure 4 As can be seen, the present invention relates to a steel strip bundling feeding device: the length measuring component 37 includes a mounting shaft I 371, a pressure wheel 372, two flanges 373, a mounting shaft II 374, a lower measuring wheel 375, and a rotary encoder 376; the upper end of the mounting shaft I 371 is fixed to the top of the bracket 32, and the lower end is connected to the pressure wheel 372; the two flanges 373 are fixed to the front and rear of the bracket 32; the mounting shaft II 374 is connected to the inner hole of the front and rear flanges 373; the lower measuring wheel 375 is mounted on its middle section; the pressure wheel 372 and the lower measuring wheel 375 are located above and below the steel strip 2 and are aligned; the rotary encoder 376 is installed at the front or rear end of the mounting shaft II 374.

[0033] After the steel belt 2 is manually extracted from the reel storage device 1, it is inserted into the belt feeding device. After passing through the guide assembly 36, the steel belt passes through the middle of the pressure wheel 372 and the lower measuring wheel 375 and reaches the clamping assembly 35. Example 4

[0034] from Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 10 , Figure 11 As can be seen, the present invention relates to a steel strip bundling feeding device: the clamping assembly 35 includes a clamping wheel hydraulic cylinder 351, a connecting shaft I 352, two front and rear swing arms 353, an eccentric shaft 354, a feeding pressure wheel 355, a feeding drive wheel 356, a hydraulic motor 357, a mounting base 358, and two front and rear bearing seats 359; the mounting base 358 is fixed on the top of the bracket 32, the connecting shaft I 352 is located on the upper part of the bracket 32, the cylinder end of the clamping wheel hydraulic cylinder 351 is hinged to the mounting base 358, and the rod end is connected to the middle section of the connecting shaft I 352; the eccentric shaft 354 is perpendicular to the front and rear surfaces of the bracket 32, and its front and rear sections and the middle section are eccentrically set; the middle section of the eccentric shaft 354 is located at the center of the frame. The bracket 32 ​​is located inside the bracket 32, with the rest extending outwards from the front and rear sides of the bracket 32. Two swing arms 353 are located outside the front and rear sides of the bracket 32, with their upper parts connected to the front and rear ends of the connecting shaft I 352 and their lower parts connected to the front and rear parts of the middle section of the eccentric shaft 354. The belt feeding pressure wheel 355 is fitted in the middle of the middle section of the eccentric shaft 354. Two bearing seats 359 are fixedly connected to the front and rear sides of the bracket 32, and the front and rear sections of the eccentric shaft 354 are engaged with the bearings in the bearing seats 359. The hydraulic motor 357 is fixed in front of or behind the bracket 32, and its output shaft is connected to the belt feeding drive wheel 356 located inside the bracket 32. The belt feeding pressure wheel 355 and the belt feeding drive wheel 356 are located above and below the steel belt 2.

[0035] 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 through the connecting shaft I 352, the two front and rear swing arms 353, and the eccentric shaft 354, a certain gap is maintained between the belt feeding pressure wheel 355 and the belt feeding drive wheel 356. After the steel belt smoothly reaches the belt feeding drive wheel 356, the proportional control hydraulic motor 357 works, which drives the steel belt to move towards the outlet and reach the straightening assembly 34 through the belt feeding drive wheel 356; from Figure 9 It can be seen that after the belt is threaded, the hydraulic cylinder 351 of the clamping wheel extends, and through the connecting shaft I 352, the two front and rear swing arms 353, and the eccentric shaft 354, the belt feeding pressure wheel 355 presses the steel belt onto the belt feeding drive wheel 356 to prevent the steel belt from retracting. Example 5

[0036] from Figure 1 , Figure 2 , Figure 3 , Figure 4As can be seen, the present invention relates to a steel bundling feeding device: a straightening assembly 34 including a mounting plate 341, a connecting shaft II 342, a moving block 343, an upper straightening adjusting wheel 344, a lower straightening wheel 345, and a connecting shaft III 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 II 342 is fixedly connected to the mounting plate 341, and the lower end is threadedly connected to the moving block 343, the upper straightening adjusting wheel 344 is connected to the lower end of the moving block 343; the connecting shaft III 346 is connected to the front and rear sides of the bracket 32, the lower straightening wheel 345 is sleeved on the middle section of the connecting shaft III 346, and the upper straightening adjusting wheel 344 and the lower straightening wheel 345 are staggered left and right.

[0037] from Figure 1 , Figure 2 , Figure 3 , Figure 4 It can be seen that, among the upper straightening adjustment wheel 344 and the lower straightening wheel 345, at least one has a greater than one quantity.

[0038] Since the steel strip is conveyed from the reel storage device, bending may occur. To ensure the quality of subsequent packaging and to ensure the steel strip adheres to the surface of the steel profile, it needs to be straightened. When the steel strip reaches the straightening assembly 34 after passing through the clamping assembly 35, it is straightened by the upper straightening adjustment wheel 344 and the lower straightening wheel 345. This ensures complete adhesion between the steel strip and the steel profile, improves the binding strength, and guarantees the safety and reliability of the product during logistics transportation. The vertical distance between the upper straightening adjustment wheel 344 and the lower straightening wheel 345 can be adjusted according to the thickness of the steel strip. Example 6

[0039] from Figure 1 , Figure 2 , Figure 3 , Figure 4 As can be seen, the present invention relates to a steel strip feeding device for bundling: a shearing assembly 38 is located on the right side of the support 32, and the shearing assembly 38 includes a base 380, a hydraulic shearing cylinder 381, a shearing blade 382, ​​a shearing blade holder 383, and a length measurement trigger sensor 384; the base 380 is fixed at the right outlet of the support 32, the hydraulic shearing cylinder 381 is fixed on the top of the base 380, the shearing blade 382 is connected to the bottom of the hydraulic shearing cylinder 381, a steel strip channel is provided between the upper and lower blade holders of the shearing blade holder 383, and the length measurement trigger sensor 384 is located on the lower blade holder of the shearing blade holder 383 and is located to the right of the shearing blade 382.

[0040] When the steel strip is conveyed forward past the shearing blade holder 383, it comes into contact with the length measurement trigger sensor 384 on the lower blade holder, which sends out a strapping measurement pulse signal. The rotary encoder 376 starts counting, and the control system measures the length of the conveyed strip by the number of pulses from the encoder. When the conveyed strip reaches the length set for bundling the steel, the hydraulic shearing cylinder 381 receives the signal and extends to cut the steel strip through the shearing blade 382, ​​thus obtaining the required length of strapping for bundling the steel. Example 7

[0041] from Figure 1 , Figure 2 , Figure 3 , Figure 4 It can be seen that the present utility model of the steel bundling feeding device: the guide component 36 also includes side guide units at the left and right ends of the guide belt groove block 362, each side guide unit includes two side guide wheels 363, and the two side guide wheels 363 are fixed on the front and rear sides of the guide belt groove block 362.

[0042] The side guide wheel 363 guides the steel belt in the front and back directions when it enters from the left end of the bracket 32 ​​and when it exits from the guide belt groove 362, ensuring that the steel belt is smoothly transported along the steel belt channel. Example 8

[0043] from Figure 1 , Figure 2 , Figure 3 , Figure 4 It can be seen that the steel strip feeding device of this utility model: the shearing assembly 38 also includes two front and rear outlet clamping rollers 385, which are fixed on the lower blade seat of the shearing blade seat 383 and arranged in front and behind.

[0044] Two exit pinch rollers 385 guide the conveyed steel strip in the forward and backward directions to ensure that the steel strip is smoothly conveyed into the steel strip bending mechanism. Example 9

[0045] from Figure 1 , Figure 2 , Figure 3 , Figure 4 It is understood that the steel bundling feeding device of this utility model 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. The displacement sensor 332 is set on the rod end of the hydraulic cylinder 331. The hydraulic cylinder 331 is connected to the left end of the bracket 32. The slider at the lower part of the bracket 32 ​​is connected to the linear guide rail 333.

[0046] If the subsequent bundling of the tape feeding device is carried out by the bundling equipment, the tape feeding device needs to be pushed to the entrance of the bundling equipment and the steel tape needs to be cut at the entrance: when the steel tape reaches below the shearing blade 382, ​​the feeding stops, 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 tape feeding point through the displacement of the extension rod of the hydraulic cylinder 331. When the shearing component reaches the front end of the bundling equipment, the hydraulic cylinder 331 stops working. At this time, the steel tape 2 continues to be fed. When the steel tape is fed forward and passes the shearing blade holder 383, it contacts the fixed length measurement trigger sensor 384 on the lower blade holder, which sends out a strapping measurement pulse signal. The rotary encoder 376 starts counting. The control system measures the tape feeding length through the number of pulses of the encoder. When the tape feeding reaches the set length for bundling the steel, the hydraulic shearing cylinder 381 receives the signal and extends to cut the steel tape through the shearing blade 382, ​​obtaining the fixed length of strapping required for bundling the steel. When the baling equipment is baling, the hydraulic cylinder 331 pulls the support 32 back to its original position on the left. After the baling equipment finishes baling, the hydraulic cylinder 331 pushes the support 32 to the front of the baling equipment for a new round of shearing.

[0047] The working principle of this utility model steel strip feeding device is as follows: the steel strip extracted from the strip storage device passes through the guide component and length measuring component to the clamping component, where it is automatically fed. After being straightened by the straightening component, the steel strip smoothly arrives at the cutting device: 1. If the bundling is done manually, the strip continues to be fed. When the length of the fed strip reaches the required length for bundling the steel, the steel strip is cut to facilitate subsequent bundling processes; 2. If the bundling is done using a bundling machine, the push component moves the base and the components above it to the set feeding point and continues to feed the strip. When the length of the fed strip reaches the required length for bundling the steel, the steel strip is cut to facilitate subsequent bundling processes.

[0048] The advantages of this utility model of a steel strip feeding device for bundling are: 1. By coordinating a length measurement trigger sensor and a rotary encoder, the cut steel strip length is made to match the required length for bundling, achieving fixed-length bundling and improving bundling efficiency; 2. The hydraulic cylinder of the clamping wheel in the clamping assembly drives the movement of the feeding and pressing wheel, realizing the conveying and pressing of the steel strip to prevent retraction; 3. The straightening assembly straightens the bent steel strip extracted from the strip reel storage device, ensuring complete adhesion between the steel strip and the steel, improving bundling strength, and ensuring the safety and reliability of product logistics and transportation; 4. When bundling is subsequently performed by the bundling equipment, the pushing assembly pushes the cutting assembly to the front of the bundling equipment before cutting, facilitating bundling; 5. The guiding assembly, length measuring assembly, clamping assembly, straightening assembly, and cutting assembly form a steel strip conveying channel, and the unobstructed flow of the channel improves the reliability and safety of the threading process.

[0049] In summary, this utility model integrates steel strip clamping, automatic length feeding, straightening and shearing devices, realizing the functions of automatic clamping of steel strips with a thickness greater than 3mm, online measurement of the feeding length, automatic straightening and leveling, and length shearing.
