Background Technology

[0002] Currently, in continuous strip processing lines in the metallurgical industry, the need to replace edge-shearing blades is widespread and frequent. Traditional designs typically configure one edge-shearing unit, but replacing the blades in this unit is time-consuming, often disrupting production rhythm and impacting unit capacity and product quality.

[0003] Therefore, it is necessary to design a shredder that can quickly switch between horizontal and vertical movements to overcome the above problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a shredder that can be quickly switched laterally. This invention solves at least some of the problems in the prior art.

[0005] This invention is implemented as follows:

[0006] This invention provides a quick-shifting edge trimmer, comprising a first edge trimming unit and a second edge trimming unit, which are connected by a connecting rod. Both the first and second edge trimming units are slidably connected to a track. The edge trimmer also includes a driving device for driving the first and second edge trimming units to slide along the track. The two sides of the track are offline positions, and the middle of the track is an online position. During operation, one set of the first and second edge trimming units is in use in the online position, while the other set is in standby in the offline position.

[0007] Furthermore, the edge trimmer, which can be quickly moved laterally, also includes a base with a track mounted on it.

[0008] Furthermore, the driving device is a transverse hydraulic cylinder, which is connected to the first edge-shearing unit.

[0009] Furthermore, both the bottom of the first edge-shearing unit and the bottom of the second edge-shearing unit are provided with wheels that can roll on the surface of the track.

[0010] Furthermore, both the bottom of the first edge-shearing unit and the bottom of the second edge-shearing unit are equipped with side wheels that serve as guides. The track is I-shaped, with the side wheels set horizontally and distributed on both sides of the track top plate.

[0011] Furthermore, the side wheel is fixed to the edge shearing unit by an eccentric sleeve.

[0012] Furthermore, rollers are provided at the bottom of both the first and second edge-shearing units. The rollers are inclined on both sides of the track and are in rolling connection with the lower surface of the track top plate.

[0013] Furthermore, the edge-shearing unit that can quickly switch between horizontal movement also includes wheel seats, forks, and pull rods. Rollers are fixed on wheel seats, and the wheel seats on both sides of the track are fixedly connected to the lower end of the forks by bolts. The bottom of the pull rod has a slot, and the upper end of the forks extends into the slot. The upper end of the forks is fixedly connected to the bottom of the pull rod by a pin. Both the first edge-shearing unit and the second edge-shearing unit are equipped with disc spring support plates. Disc springs are placed on disc spring support plates, and disc spring boxes cover the disc springs. The upper end of the pull rod passes through the disc spring support plate, the disc spring, and the disc spring box in sequence and is then locked with a nut.

[0014] Furthermore, a pad is provided between the top of the disc spring and the inner wall of the disc spring box.

[0015] Furthermore, both the first and second edge-shearing units are equipped with guide sliders, which are located on both sides of the pull rod.

[0016] The present invention has the following beneficial effects:

[0017] This invention provides a quick-switching edge trimmer, employing two sets of edge trimming units. One set is in operation while the other is offline. When the blades of the online edge trimmer need replacement, to avoid disrupting production, the offline edge trimmer can be quickly switched to the online position using a horizontal hydraulic cylinder. This allows for maintenance of the online edge trimmer, reducing downtime, increasing production capacity, and preventing losses caused by prolonged downtime. Attached Figure Description

Detailed Implementation

[0033] 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.

[0034] like Figures 1-13 This invention provides a quick-switchable edge trimming shear, comprising a first edge trimming unit 1 and a second edge trimming unit 2, connected by a connecting rod 20. Both the first and second edge trimming units 1 and 2 are slidably connected to a track 5. The shear also includes a driving device for driving the first and second edge trimming units 1 and 2 to slide along the track 5. The two sides of the track 5 are offline positions, and the middle of the track 5 is the online position. During operation, one set of the first and second edge trimming units 1 and 2 is in use in the online position, while the other set is in standby in the offline position. When the blade of the edge trimming unit in the online position needs to be replaced, in order not to affect the production rhythm, the offline edge trimming unit can be quickly switched to the online position for use by a horizontal hydraulic cylinder 3, and the online edge trimming unit can be switched to the offline position for maintenance.

[0035] The edge trimmer, which can be quickly moved and switched horizontally, also includes a base 4, and a track 5 is mounted on the base 4.

[0036] The driving device is a transverse hydraulic cylinder 3, which is connected to the bottom of the first edge-shearing unit 1, driving the first edge-shearing unit 1 and the second edge-shearing unit 2 to move together. The transverse hydraulic cylinder 3 can also be connected to the second edge-shearing unit 2. In another embodiment, a geared motor driving wheels can be used instead of the transverse hydraulic cylinder 3.

[0037] like Figure 9 The bottom of the first edge-shearing unit 1 and the bottom of the second edge-shearing unit 2 are both provided with wheels 6 that can roll on the surface of the track 5.

[0038] like Figures 9-11 The bottom of the first edge-shearing unit 1 and the bottom of the second edge-shearing unit 2 are both equipped with side wheels 7 that serve as guides. The track 5 is I-shaped, and the side wheels 7 are horizontally arranged and distributed on both sides of the track top plate 21. The side wheels 7 are fixed to the edge-shearing unit by eccentric sleeves 9.

[0039] like Figures 12-13The bottom of the first edge-shredding unit 1 and the bottom of the second edge-shredding unit 2 are both equipped with rollers 8. The rollers 8 are inclinedly arranged on both sides of the track 5 and are in rolling connection with the lower surface of the track top plate 21. The edge-shredding shear that can be quickly moved and switched also includes wheel seats 18, forks 17, and pull rods 14. The rollers 8 are fixed on the wheel seats 18. The wheel seats 18 on both sides of the track 5 are fixedly connected to the lower end of the forks 17 by bolts. The bottom of the pull rod 14 is provided with a slot. The upper end of the forks 17 extends into the slot. The upper end of the forks 17 is fixedly connected to the bottom of the pull rod 14 by a pin 16. The frame of the first edge-shredding unit 1 and the frame of the second edge-shredding unit 2 are both equipped with disc spring support plates 19. Disc springs 13 are placed on the disc spring support plates 19. Disc spring boxes 11 cover the disc springs 13. The upper end of the pull rod 14 passes through the disc spring support plates 19, disc springs 13, and disc spring boxes 11 in sequence and is locked by nuts 10. A pad 12 is provided between the top of the disc spring 13 and the inner wall of the disc spring box 11. The pad 12 acts as a washer.

[0040] The lower end of the wheel seat 18 has an opening for mounting the roller 8, and the upper end of the wheel seat 18 has an opening for the fork head 17 to extend into. Bolts pass through the wheel seat 18 and the fork head 17 and are then tightened. The roller 8 prevents the edge-shearing unit from tipping over, bearing the tipping torque while ensuring the wheel 6 remains in close contact with the upper surface of the track, thanks to the preload generated by the compressed disc spring 13. There is a gap between the lower end of the disc spring box 11 and the disc spring support plate 19; the size of this gap is related to the amount of disc spring compression, and the size of the gap indicates the magnitude of the disc spring preload. The disc spring support plate 19 is fixed to the frame of the edge-shearing unit 2 by bolts.

[0041] Guide sliders 15 are provided on the frames of both the first edge-shearing unit 1 and the second edge-shearing unit 2. The sliders 15 are located on both sides of the pull rod 14. When the disc spring is preloaded, the sliders 15 serve as guides.

[0042] The slider 15 guides the vertical movement of the pull rod 14, keeping the pull rod 14 in a vertical position.

[0043] This invention provides a quick-shifting edge-shearing unit, comprising a first edge-shearing unit 1, a second edge-shearing unit 2, a horizontal hydraulic cylinder 3, a base 4, a track 5, and a connecting rod 20. The first edge-shearing unit 1 and the second edge-shearing unit 2 are connected by the connecting rod 20 and can move along the track 5 mounted on the base 4 via the horizontal hydraulic cylinder 3.

[0044] One of the first edge-shredding unit 1 and the second edge-shredding unit 2 is in operation while the other is offline. When the blades of the edge-shredding unit in the online position need to be replaced, in order not to affect the production rhythm, the offline edge-shredding unit can be quickly switched to the online position for operation using the transverse hydraulic cylinder 3, and the online edge-shredding unit can be switched to the offline position for maintenance.

[0045] The edge-shearing unit moves on the track 5 via the wheels 6 under the guidance of the side wheels 7. The side wheels 7 are fixed to the shearing unit by the eccentric sleeve 9, and the gap between the side wheels 7 and the track 5 can be adjusted by rotating the eccentric sleeve 9 with the elongated hole.

[0046] The edge-shearing unit is clamped on the track by the action of nut 10, disc spring box 11, pad 12, disc spring 13, pull rod 14, slider 15, pin 16, fork head 17, wheel seat 18 and roller 8 to withstand vibration and impact loads.

[0047] This invention provides a shredder with rapid lateral switching, which enables quick switching of shredder cutting units and avoids losses in unit capacity and product quality caused by prolonged unit downtime.

[0048] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0049] The above description is only 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.
