Description

Technical Field

[0001] This invention relates to the field of steel strip feeding technology, and more specifically, to a steel strip feeding device. Background Technology

[0002] The steel strip feeding device mainly transports the raw material in coils to the replacement position. The feeding rack has a flexible rotation function. It steadily rotates and feeds the steel strip from the steel strip roller with appropriate force and angle. The steel strip is accurately fed to the corresponding station of the forming machine, preparing it for subsequent forming processing.

[0003] In the prior art, patent publication number CN210064627U discloses a steel strip reel feeding device. This technology includes a T-shaped support rod comprising an inclined inner arm fixedly connected to a tensioning shaft, an inclined outer arm circumferentially mounted on a conversion disc and slidably connected to the conversion disc via a sliding assembly, and an arc-shaped support rod fixedly mounted on the outside of the inclined outer arm. The inclined outer arm and the inclined inner arm are slidably engaged via a second sliding assembly. This utility model facilitates feeding and does not affect the normal operation of the production line. However, this technology has the following problems.

[0004] In the steel strip feeding process, when the steel strip is used up and needs to be replaced with a corresponding model, if the steel strip model does not match the feeding requirements, forcibly feeding the abnormal model steel strip will have serious consequences. On the one hand, the feeding device will be damaged due to incompatibility, affecting normal operation and service life. On the other hand, it will lead to abnormal working conditions in the processing, reduce product quality, and even cause production accidents. Currently, it is difficult to achieve full-range abnormal protection for the outer and middle layers of steel strip feeding, and it is difficult to effectively avoid the problem of forced feeding. Summary of the Invention

[0022] A connecting block is fixed on the upper inclined surface of the bracket. A pull column is fixed on one side of the connecting block. A groove is opened on the inner wall of the pull frame. The pull column and the pull frame to which the groove belongs are slidably connected. The pull frame is used to pull the pull column to rotate.

[0023] A collar is fixedly connected to the top of the bracket. A positioning shaft is installed on the inner wall of the collar. The positioning shaft is used to position the rotation of the collar. The positioning shaft is fixedly connected to the groove plate.

[0025] In a preferred embodiment, both the groove plate and the pull-groove frame are slidably connected to the bracket, and the center point of the pull column is lower than the center point of the positioning axis.

[0026] In a preferred embodiment, the driving unit includes:

[0028] In a preferred embodiment, the detection of the loading component includes:

[0029] A support shaft is fixedly connected to the bottom end of the trough plate. A feeding roller is rotatably connected to the outer wall of the support shaft, and multiple sets of support rods are fixedly connected to the outer wall of the feeding roller.

[0030] A feeding plate is fixedly connected to the top of the support rod, a support plate is fixedly connected to one end of the support shaft, and a mounting bracket is fixed to the bottom end of the support plate;

[0031] A bushing is fixedly installed on the top of the mounting frame. The bushing is rotatably connected to the feeding roller and is used to position the rotation of the feeding roller.

[0032] The controller is installed on one side of the mounting bracket, and a barcode recognition sensor is installed on the inner wall of the mounting bracket. The barcode recognition sensor is electrically connected to the controller and is used to recognize the barcode on the steel strip.

[0033] In a preferred embodiment, a feeding sleeve is provided on one side of the barcode recognition sensor. The feeding sleeve is slidably inserted into the outer wall of the feeding plate, and the outer wall of the feeding sleeve is provided with a plurality of threaded bolts.

[0034] The technical effects and advantages of the present invention.

[0035] 1. This invention employs a linkage between the outer and middle feeding restrictors. After the barcode recognition sensor detects a model mismatch signal, the controller can synchronously start the electric cylinder, driving the rack to move, so that the adjusting plate and the blocking bar can be quickly positioned, forming a dual physical restriction covering the abnormal range of "large size" and "small size" of the inner diameter of the steel strip. This achieves full-range abnormal protection from the "outer periphery" to the "middle periphery," preventing abnormal steel strips from being forcibly fed, and effectively ensuring the safety and accuracy of the feeding device.

[0036] 2. This invention uses an external feeding restraint component that meshes with a gear and rack to drive the adjusting plate to rotate to the inclined position. Gravity is used to make the displacement rod slide down along the inner wall of the adjusting plate, forming a stable "V"-shaped inclined blocking area with the adjusting plate. The displacement rod is attracted and locked to the adjusting plate by a first electromagnet. The limiting block and pad ensure smooth movement. By using gravity and electromagnetic locking, no complex power is required to form a reliable external barrier for large inner diameter abnormal steel strips, preventing abnormal steel strips from being forcibly fed.

[0037] 3. This invention employs a central feeding restraint component. The rack drives the groove frame to move, and through the sliding engagement between the pull column and the groove body, the support, arc plate, and blocking strip are driven to rotate and stand upright around the positioning axis. The fulcrum design of the pull column and the arc-shaped structure of the arc plate enable the blocking strip to rotate stably to the working position and effectively buffer and block abnormal steel strips with small inner diameters. This supplements the blind spot of the central restraint and prevents abnormal steel strips from being forcibly fed, causing impact damage to the equipment or the steel strip.

[0048] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0049] The present invention will be further described in detail below with reference to the figures.

[0050] Example 1: As Figure 1 - Figure 9 The steel strip feeding device shown includes a trough plate 1 with a rack 2 installed inside it; an outer feeding limiter installed on one side of the rack 2, with an adjusting plate 3 on the outer feeding limiter and a displacement rod 4 slidably connected to the inner wall of the adjusting plate 3; a middle feeding limiter installed on the other side of the rack 2, with a blocking strip 5 installed on the middle limiting member; a drive unit installed at the bottom of the rack 2; and a detection feeding device located at the bottom of the trough plate 1. The electric cylinder 31, the second electromagnet 9, the first electromagnet 7, and the barcode recognition sensor 28 are all electrically connected to the controller 27.

[0051] The operating principle of this embodiment is as follows: when steel strip needs to be replaced, the steel strip is coiled together. When the detection component detects that the steel strip model is different from the model to be fed, the drive unit starts to drive the rack 2 to move upward. The rack 2 drives the outer feeding restriction component to rotate the adjusting plate 3 180 degrees to the top of the channel plate 1, that is, the adjusting plate 3 rotates half a turn. At this time, the adjusting plate 3 is in an inclined state. By using gravity, the displacement rod 4 moves downward along the inside of the adjusting plate 3 to restrict the outer feeding of the steel strip. The upward movement of the rack 2 drives the middle feeding restriction component, which drives the blocking bar 5 to rotate to the front of the channel plate 1 to restrict the middle feeding of the steel strip. This provides outer and middle coverage restriction for abnormal steel strip models, preventing abnormal steel strip models from being forcibly fed. It achieves full-range abnormal protection of the outer and middle perimeters, effectively avoiding the problem of forced feeding.

[0052] Example 2: In this example, as Figure 1 - Figure 5 As shown, the peripheral loading limiting components include: a gear 32, meshing and connected to one side of the rack 2, and fixedly connected to the adjusting plate 3; a shaft 33 rotatably connected to the inner wall of the gear 32, and fixedly connected to the slot plate 1; the shaft 33 is used to position the rotation of the adjusting plate 3; a sleeve 11, fixed to the outer wall of the displacement rod 4 and located below the adjusting plate 3; a soft pad 6 connected to the upper inclined surface of the sleeve 11; a first electromagnet 7, fixed to one side of the inner wall of the sleeve 11; the upper inclined surface of the first electromagnet 7 is parallel to the lower inclined surface of the adjusting plate 3; a limiting block 8, fixed to the top of the displacement rod 4; a second electromagnet 9 installed on one side of the limiting block 8; the second electromagnet 9 is used to magnetically attract the adjusting plate 3; pads 10 are fixedly connected to both sides of the inner wall of the limiting block 8, and the pads 10 slide in contact with the adjusting plate 3. A gap is provided between the rack 2 and the adjusting plate 3, and the adjusting plate 3 is inclined. The second electromagnet 9 is vertically positioned between the limiting block 8 and the limiting block 8.

[0053] The operating principle of this embodiment is as follows: when the steel strip model detected by the feed component is different from the feed model, the rack 2 moves upward, and the rack 2 meshes with the gear 32, causing it to rotate clockwise. At this time, the gear 32 rotates clockwise on the outer wall of the shaft 33, and the gear 32 drives the adjusting plate 3 to rotate clockwise. The adjusting plate 3 drives the second electromagnet 9 to rotate clockwise. The second electromagnet 9 is then magnetically locked with the adjusting plate 3, and the second electromagnet 9 drives the limiting block 8 to rotate clockwise. The limiting block 8 drives the two pads 10 to rotate clockwise. The pads 10 play a certain buffering contact role between the adjusting plate 3 and the limiting block 8. At the same time, the limiting block 8 drives the displacement rod 4 to rotate clockwise, the displacement rod 4 drives the sleeve 11 to rotate clockwise, and the sleeve 11 drives the first electromagnet 7 to rotate clockwise. When the adjusting plate 3 rotates to the top of the slot plate 1, and the adjusting plate 3 is tilted after rotating 180 degrees, the limiting block 8 faces downward and the sleeve 11 faces upward.

[0054] The controller 27 closes the second electromagnet 9, so the second electromagnet 9 no longer magnetically locks the adjusting plate 3. At the same time, the first electromagnet 7 is opened. Under the gravity of the displacement rod 4, the displacement rod 4 tilts and moves downward along the inner wall of the adjusting plate 3. The displacement rod 4 drives the sleeve 11 to tilt and move downward. The sleeve 11 drives the first electromagnet 7 to tilt and move downward. The sleeve 11 causes the soft pad 6 to tilt and move downward. The lower surface of the soft pad 6 contacts the adjusting plate 3 for buffering. At the same time, the first electromagnet 7 contacts the adjusting plate 3 and magnetically locks the adjusting plate 3. At this time, the displacement rod 4 and the adjusting plate 3 form V-shaped restriction areas in different directions above the slot plate 1, which restricts the feeding of steel strips with large inner diameters. Since the adjusting plate 3 and the displacement rod 4 are both tilted, there is no flat area, so steel strips with large inner diameters cannot be placed in the feeding area. This prevents the forced feeding of abnormal steel strips, realizes full-range abnormal protection, and effectively avoids the problem of forced feeding.

[0055] Example 3: In this example, as Figure 2 - Figure 7 As shown, the middle-wall loading restriction component includes: a grooved frame 16, fixed to the other side of the rack 2; an arc-shaped plate 12, fixedly connected to the inner wall of the blocking strip 5, with a bracket 13 connected to the inner wall of the arc-shaped plate 12; a connecting block 14, fixed to the upper inclined surface of the bracket 13, with a pull column 15 fixed to one side of the connecting block 14; a groove 17 is formed in the inner wall of the grooved frame 16, and the pull column 15 is slidably connected to the grooved frame 16 to which the groove 17 belongs, the grooved frame 16 being used to pull the pull column 15 to rotate; and a collar 18, fixedly connected to the top of the bracket 13, with a positioning shaft 19 installed on the inner wall of the collar 18, the positioning shaft 19 being used to position the collar 18 to rotate, and the positioning shaft 19 being fixedly connected to the groove plate 1. The blocking strip 5 and the bracket 13 are both fixedly connected to the arc-shaped plate 12, the vertical cross-section of which is arc-shaped. Both the groove plate 1 and the pull frame 16 are slidably connected to the bracket 13, and the center point of the pull column 15 is lower than the center point of the positioning shaft 19.

[0056] The operating principle of this embodiment is as follows: When the detected steel strip model is different from the feeding model, the rack 2 moves upward, which in turn moves the groove frame 16 upward. The groove frame 16 pulls the pull column 15 upward, causing the pull column 15 to rotate clockwise. Simultaneously, the pull column 15 slides along the inner wall of the groove 17, and the pull column 15 causes the connecting block 14 to rotate clockwise. The connecting block 14 then drives the bracket 13 to rotate clockwise, which in turn causes the collar 18 to rotate clockwise. The collar 18 rotates clockwise along the outer wall of the positioning shaft 19, supporting the positioning shaft 19 through the groove plate 1. At the same time, the bracket 13 drives the arc-shaped... The plate 12 rotates clockwise, causing the blocking strip 5 to rotate clockwise as well. The blocking strip 5 is located in the front area of ​​the channel plate 1, so that the steel strip with a small inner diameter directly contacts the outer wall of the blocking strip 5 and is buffered and limited by the blocking strip 5. At the same time, the pull frame 16 supports the pull column 15, the pull column 15 supports the connecting block 14, the connecting block 14 supports the bracket 13, and the bracket 13 supports the arc plate 12 to provide support force to the blocking strip 5. In this way, the steel strip with a small inner diameter is restricted from being fed in the middle, preventing the forced feeding of abnormal steel strips, realizing full-range abnormal protection, and effectively avoiding the problem of forced feeding.

[0057] Example 4: In this example, as Figure 2 - Figure 8 As shown, the drive unit includes an electric cylinder 31 located at the bottom end of the rack 2. The output end of the electric cylinder 31 is fixedly connected to the rack 2, and the outer wall of the electric cylinder 31 is fixedly connected to the slot plate 1. The electric cylinder 31 is used to push the rack 2 to move.

[0058] The operating principle of this embodiment is that when the detected steel strip model is different from the feeding model, the controller 27 immediately starts the electric cylinder 31, and the output end of the electric cylinder 31 pushes the rack 2 to achieve upward drive, realizing the output of power.

[0059] Example 5: In this example, as Figure 8 - Figure 9As shown, the detection and feeding component includes: a support shaft 20, fixedly connected to the bottom end of the trough plate 1, with a feeding roller 21 rotatably connected to the outer wall of the support shaft 20, and multiple sets of support rods 22 fixedly connected to the outer wall of the feeding roller 21; a feeding plate 23, fixedly connected to the top end of the support rods 22, with a support plate 25 fixedly connected to one end of the support shaft 20, and a mounting frame 26 fixed to the bottom end of the support plate 25; a bushing 24, fixedly installed on the top end of the mounting frame 26, with a rotatable connection between the bushing 24 and the feeding roller 21, and the bushing 24 is used to position the rotation of the feeding roller 21; and a controller 27, installed on one side of the mounting frame 26, with a barcode recognition sensor 28 installed on the inner wall of the mounting frame 26, and the barcode recognition sensor 28 is electrically connected to the controller 27, and the barcode recognition sensor 28 is used to recognize the barcode of the steel strip. A feeding sleeve 29 is provided on one side of the barcode recognition sensor 28. The feeding sleeve 29 is used to slide and insert onto the outer wall of the feeding plate 23. The outer wall of the feeding sleeve 29 is provided with multiple threaded bolts 30.

[0060] The operating principle of this embodiment is as follows: The mounting bracket 26 is fixed by inserting pre-embedded bolts into the bottom holes. The barcode on the steel strip is then positioned at the barcode recognition sensor 28. The barcode value is recognized by the sensor. When the recognized barcode value matches the loading barcode value set on the controller 27, the steel strip is directly sleeved onto the outer wall of the multiple loading plates 23. By moving the loading sleeve 29 to the right, it slides along the outer wall of the loading plate 23. Finally, by rotating the bolt 30, the bolt engages with the loading sleeve 29, thereby tightening the screw... The bolt 30 presses against the outer wall of the feeding plate 23 to limit the steel strip. When the steel strip rotates during feeding, it drives the feeding plate 23 to rotate. The feeding plate 23 causes the support rod 22 to rotate, and the support rod 22 drives the feeding roller 21 to rotate. Because the feeding roller 21 is divided into two sections, one end extends to the left side of the bushing 24, and the other end is located on the inner wall of the bushing 24, the feeding roller 21 rotates stably inside the bushing 24. The mounting bracket 26 supports the support plate 25, and the support plate 25 supports the support shaft 20, improving the stability of the support shaft 20 and ensuring that the feeding roller 21 continues to rotate and feed while keeping the support shaft 20 stationary.

[0061] The barcode of the steel strip is placed at the position of the barcode recognition sensor 28. The barcode value is recognized by the barcode recognition sensor 28. When the recognized barcode value is different from the loading barcode value set on the controller 27, the controller 27 immediately restricts the coverage of the outer and middle parts to prevent the steel strip of abnormal type from being forcibly loaded, thus realizing full-range abnormal protection of the outer and middle parts.

[0062] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
