Description

Technical Field

[0001] This invention relates to the field of metal sheet, strip, and foil production and processing technology, specifically a thin strip feeding structure. Background Technology

[0002] As market demand for the width and thickness of metal strips changes, manufacturers are producing metal strips that are wider and thinner. However, wide foil materials are difficult to thread during production due to their large width and thinness, requiring manual pulling and feeding. This poses a safety hazard to production personnel and is not conducive to improving production efficiency.

[0003] In current production, guide plates are generally used for feeding, which is suitable for thick strips and sheets. However, for thin strips, due to their thinness, plastic deformation is more likely to occur during the feeding process. Especially in the cold rolling of metals, rolling oil is sprayed, and the oil film on the surface of the strip is easily adsorbed on the guide plate, making it difficult to feed forward. Especially when the width is large, two people are needed to assist in feeding from both sides, which results in wasted manpower and safety hazards. In addition, for feeding coils with different outer diameters, the position of the coil needs to be adjusted according to its outer diameter, which is inconvenient to operate. Therefore, we propose a feeding structure for thin strips. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a thin strip feeding structure. The head receiving guide plate first guides the strip onto the belt of the conveyor roller mechanism, and then the belt movement drives the strip movement, realizing the unobstructed transmission of the thin strip, avoiding plastic deformation of the thin strip during the process, improving product quality, and effectively solving the problems in the background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a thin strip feeding structure, comprising: a receiving guide plate for guiding the thin strip before it enters the conveyor belt; an adjustable conveyor roller mechanism connected to the receiving guide plate for conveying the thin strip; a swing mechanism disposed below the conveyor roller mechanism for driving the conveyor roller mechanism and the receiving guide plate to swing around a fixed axis disposed at an end away from the receiving guide plate; a tensioning mechanism disposed on the conveyor roller mechanism for adjusting the tension of the conveyor roller mechanism; and an anti-deviation mechanism disposed on the conveyor roller mechanism for preventing the conveyor belt from deviating.

[0006] As a preferred embodiment of the present invention, the conveying roller mechanism includes a "mountain"-shaped movable support, two symmetrically arranged conveyor belts, fixed supports arranged on both sides and in the middle, and two sets of electric rollers fixedly arranged on the fixed supports. A receiving guide plate is arranged on the movable support at one end away from the fixed axis. The two conveyor belts are respectively arranged on both sides of the movable support. The two sets of electric rollers are arranged on the side close to the fixed axis and are arranged vertically opposite each other. The movable support is provided with two sets of follower rollers that move with the movable support. The follower roller on the upper side is on the same straight line as the electric roller on the upper side, and the follower roller on the lower side is located in the middle of the two sets of electric rollers. A set of fixed rollers is also provided in the middle of the fixed support. The fixed rollers are on the same straight line as the electric roller on the lower side. The conveyor belts are wound around the upper follower roller, the upper electric roller, the lower electric roller, the fixed roller, the lower follower roller, and the upper follower roller in that order.

[0007] As a preferred embodiment of the present invention, a movable hydraulic cylinder is provided on the lower surface of the movable support, and the movable hydraulic cylinder drives the movable support to move back and forth along the conveying direction of the thin strip.

A tie rod is disposed between the fixing plate and the adjusting support. Two limiting rings respectively disposed on both sides of the adjusting support are fixed on the tie rod, and a fastening nut is threadedly connected to the side of the fixing plate away from the adjusting support.

[0010] As a preferred embodiment of the present invention, the anti-deviation mechanism includes an annular groove formed on the outer surface of the follower roller, the fixed roller, and the electric roller. The annular groove is evenly distributed along the axial direction of the follower roller, the fixed roller, or the electric roller. The inner surface of the conveyor belt is provided with a protrusion that engages with the annular groove.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: The adjustable conveyor roller mechanism, in conjunction with the receiving guide plate, conveys thin strip material, replacing the traditional guide plate feeding method.

Detailed Implementation

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figure 1-8This invention provides a technical solution: a thin strip feeding structure, comprising: a receiving guide plate 1, an adjustable conveyor roller mechanism, and a swing mechanism. The receiving guide plate 1 is used to guide the belt transition before the thin strip enters the conveyor roller mechanism. The conveyor roller mechanism is connected to the receiving guide plate 1 and is used to convey the thin strip. The thin strip is conveyed by the adjustable conveyor roller mechanism in conjunction with the receiving guide plate 1, replacing the traditional guide plate feeding. The receiving guide plate 1 first guides the strip onto the conveyor roller mechanism's belt, and then the belt movement drives the strip movement, achieving unobstructed conveying of the thin strip. This avoids plastic deformation of the thin strip during travel, improving product quality. At the same time, the conveyor roller mechanism can adjust the length of the conveying section, making it suitable for receiving and feeding rolls of different outer diameters, thus improving versatility.

[0016] The swing mechanism is located on the lower side of the conveying roller mechanism, driving the conveying roller mechanism and the receiving guide plate 1 to swing around a fixed axis located at one end away from the receiving guide plate 1. This is also to accommodate material rolls with different outer diameters. When receiving material, it is only necessary to adjust the angle of the conveying roller mechanism through the swing mechanism and adjust the length of the conveying roller according to the outer diameter of the material roll. The adjustment is simple, the operation is convenient, and the work efficiency is improved.

[0017] Specifically, the conveyor roller mechanism includes a "mountain"-shaped movable support 3, two symmetrically arranged conveyor belts 6, fixed supports on both sides and in the middle, and two sets of electric rollers 7 fixedly mounted on the fixed supports. The electric rollers 7 are driven by a motor or other drive mechanism and are the driving rollers of the entire conveyor roller mechanism. The conveyor belts 6 are the conveyor belts of the conveyor roller mechanism. The receiving guide plate 1 is located on the movable support 3 at the end away from the fixed axis. The two conveyor belts 6 are respectively located on both sides of the movable support 3. The two conveyor belts 6 can meet the feeding requirements of wide and thin strip materials. The two sets of electric rollers 7 are located near the fixed axis. The conveyor belt 6 is arranged on one side and vertically opposite each other. The movable support 3 is equipped with two sets of follower rollers 2 that move with the movable support 3. The follower roller 2 on the upper side is on the same straight line as the electric roller 7 on the upper side, and the follower roller 2 on the lower side is located in the middle of the two sets of electric rollers 7. The fixed support is also equipped with a set of fixed rollers 4 in the middle. The fixed roller 4 is on the same straight line as the electric roller 7 on the lower side. The conveyor belt 6 is wound around the upper follower roller 2, the upper electric roller 7, the lower electric roller 7, the fixed roller 4, the lower follower roller 2, and the upper follower roller 2 in sequence. A total of ten rollers are arranged in two rows symmetrically, corresponding to the two conveyor belts 6 respectively. Taking one row as an example: two electric rollers 7, two follower rollers 2, and one fixed roller 4 are arranged in parallel winding. The two electric rollers 7 are fixed on a fixed bracket, which is rotatably set on the outside of the fixed shaft. The fixed roller 4 is fixed in the middle of the fixed bracket, and the remaining two follower rollers 2 are fixed on a movable bracket 3. Each group of five rollers is arranged in parallel vertically. The ingenious structure ensures that the total length of the conveyor belt 6 does not change during the winding process. According to the outer diameter of the material roll, the position of the movable bracket 3 is adjusted, so that the two follower rollers 2 move back and forth, adjusting the length of the uppermost conveyor belt 6. This can be used for receiving and feeding material rolls with different outer diameters without changing the overall length of the conveyor belt 6.

[0018] Specifically, a moving hydraulic cylinder 5 is provided on the lower surface of the moving support 3. The moving hydraulic cylinder 5 drives the moving support 3 to move back and forth along the conveying direction of the thin strip. The moving hydraulic cylinder 5 can also be an oil cylinder or a pneumatic cylinder.

[0019] Optionally, a detachable movable interface for the conveyor belt 6 to pass through is provided on the movable support 3 to meet the needs of conveying, winding, maintenance and replacement of the conveyor belt 6. Specifically, on both sides of the front section of the movable support 3, the bracket for supporting the follower roller 2 is fixed to the movable support 3 by a total of eight bolts (six on the outside and two in the middle) at the conveyor belt 6 on each side. This can increase the rigidity and strength of the movable guide plate and also allow the roller bracket and receiving guide plate to be installed on it.

[0020] Without this movable interface, the entire moving support is enclosed, and the belt needs to be wound from the moving support to the oscillating guide plate. Because the belt is enclosed, a cutout for the belt must be made in the moving support to achieve winding on the rollers. The removal of this movable interface allows for belt feeding, winding, and subsequent maintenance and replacement.

[0021] In a preferred embodiment, the swing mechanism includes a swing guide plate 8 fixedly connected to a fixed bracket. A swing hydraulic cylinder 9 is hinged to the lower surface of the swing guide plate 8 and hinged to the outer fixed frame. A movable bracket 3 is slidably mounted on the upper surface of the swing guide plate 8, and a movable hydraulic cylinder 5 is fixedly mounted on the upper surface of the swing guide plate 8. Since the height of material rolls with different outer diameters is also different, it is necessary to adjust the position of the receiving guide plate 1. By extending and retracting the swing hydraulic cylinder 9, the swing guide plate 8 is driven to rotate around a fixed axis, thereby driving the movable bracket 3 and the receiving guide plate 1 to rotate and adjust the height to suit the receiving and feeding of material rolls with different outer diameters, further improving versatility.

[0022] In a further preferred technical solution, two vertical plates are symmetrically arranged on both sides of the upper surface of the swing guide plate 8. A linear guide rail 10 is fixedly arranged on the upper surface of the vertical plates. Slide grooves matching the linear guide rail 10 are opened on both sides of the lower surface of the movable support 3. When the movable hydraulic cylinder 5 extends and retracts, the movable support 3 moves back and forth on the linear guide rail 10 along the conveying direction of the thin strip, thereby realizing the adjustability of the conveying roller mechanism.

[0023] Furthermore, both the linear guide 10 and the slide are "I" or "T" shaped, making the moving bracket 3 more stable when moving.

[0024] In a preferred embodiment, a material head detector 11 is provided on the side surface of the movable support 3 away from the fixed axis. The material head detector 11 is located on the lower side of the receiving guide plate 1. It can be a sensor component such as a vision sensor or a limit switch, used to detect the material head, and automatically adjust the switching of the conveying roller mechanism and the swing mechanism through the control system, thereby improving the intelligence of the feeding structure and further improving work efficiency.

[0025] In a preferred embodiment, the thin strip feeding structure further includes a tensioning mechanism and an anti-deviation mechanism. The tensioning mechanism is mounted on the conveyor roller mechanism to adjust the tension of the conveyor roller mechanism, and the anti-deviation mechanism is mounted on the conveyor roller mechanism to prevent the conveyor belt from deviating.

[0026] Specifically, the tensioning mechanism includes an adjusting support 12 fixedly disposed on the outside of the fixed roller 4 and an L-shaped plate fixedly disposed on the upper surface of the swing guide plate 8. A support seat is fixedly disposed on the upper surface of the fixed support, and the adjusting support 12 is placed on the support seat. A fixing plate 15 is fixedly disposed on the side surface of the L-shaped plate by bolts. A pull rod 13 is disposed between the fixing plate 15 and the adjusting support 12. Two limiting rings are fixed on the pull rod 13 respectively disposed on both sides of the adjusting support 12. A fastening nut 14 is threadedly connected to the side of the fixing plate 15 away from the adjusting support 12. The through hole on the adjusting support 12 is an elongated hole. Loosening the fastening nut 14 and pulling the adjusting support 12 can move the fixed roller 4 freely along the belt conveying direction, thereby adjusting the tension of the conveyor belt 6. Alternatively, by rotating the fastening nut 14, the pull rod 13 can be moved back and forth, driving the adjusting support 12 to move, thereby adjusting the tension of the conveyor belt 6.

[0027] Optionally, the outer surface of the adjusting support 12 is provided with a slider, and a groove corresponding to the slider is opened on the inner surface of the vertical plate of the swing guide plate 8, so that the adjusting support 12 can only move back and forth in the direction horizontal to the swing guide plate 8 through the slider and cannot move up and down. After tightening the pull rod screw 13 and the fastening nut 14, the fixed roller 4 can be fixed, ensuring the stability of the conveyor belt 6 when it is conveyed on the roller.

[0028] Specifically, the anti-deviation mechanism includes an annular groove 16 formed on the outer surface of the follower roller 2, the fixed roller 4, and the electric roller 7. The annular groove 16 is evenly distributed along the axial direction of the follower roller 2, the fixed roller 4, or the electric roller 7. The inner surface of the conveyor belt 6 is provided with a protrusion 17 that engages with the annular groove 16. The special structural design of the conveyor belt 6 and each roller allows the conveyor belt 6 to be engaged in the annular groove 16 of the roller through the protrusion 17, effectively preventing belt deviation.

[0029] The present invention also provides another embodiment, please refer to the following for details. Figure 7 Similar to the previous embodiment, the difference is that the anti-deviation mechanism includes grooves 18 evenly distributed on the outer surfaces of the follower roller 2, the fixed roller 4, and the electric roller 7. The grooves 18 are evenly distributed radially along the follower roller 2, the fixed roller 4, or the electric roller 7. The inner surface of the conveyor belt 6 is evenly provided with locking strips 19 that engage with the grooves 18. The length direction of the grooves 18 and the locking strips 19 are both in the axial direction of the rollers. Furthermore, each roller has multiple non-connected grooves 18 on its outer side, which can effectively prevent the conveyor belt 6 from shifting left or right.

[0030] The bottom surfaces of the groove 18 and the card strip 19 are both arc-shaped transitions. When the conveyor belt 6 shifts forward and backward, the card strip 19 can still be engaged in the nearest groove 18 after the shift, ensuring that it will not shift left and right and cause damage to the thin strip.

[0031] The present invention also provides another embodiment, please refer to the following for details. Figure 8 Similar to the previous embodiment, the difference lies in that: the anti-deviation mechanism includes slots evenly distributed on the outer surfaces of the follower roller 2, the fixed roller 4, and the electric roller 7. The slots are evenly distributed along the circumference and axial direction of the rollers. The inner surface of the conveyor belt 6 is evenly provided with locking blocks 20 that engage with the slots. The locking blocks 20 are arranged in an array, and the bottom surface of the locking blocks 20 and the bottom surface of the slots are both spherical. Anti-slip textures are provided on the outer side of the spherical surfaces. The evenly distributed multiple sets of locking blocks 20 and slots can increase the contact area and locking points between the conveyor belt 6 and the rollers, thereby further enhancing its anti-deviation function.

[0032] All parts not disclosed in this invention are prior art, and their specific structures, materials, and working principles will not be described in detail. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
