[0064] The technical solutions of the present application will be described in detail below with reference to the drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present application and not to limit the scope of the present application. After reading the present application, those skilled in the art can make various equivalent modifications to the present application, which fall within the scope of the appended claims.

[0065] It should be noted that when an element is referred to as "disposed on" another element, it can be directly on the other element or there can be intervening elements. When an element is referred to as "connected" to another element, it can be directly connected to the other element or there can be intervening elements. The terms "vertical", "horizontal", "upper", "lower", "left", "right", and similar terms as used herein are for purposes of description only and are not intended to be limiting.

[0066] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0067] The current waste edge coiling machine is used, and the workers wind the waste materials on the outer wall of the coiling roller. Then the motor is started to drive the coiling roller to rotate. At this time, the waste materials can be coiled and collected. When the workers need to take down the waste materials from the coiling roller, the workers need to disassemble the coiling roller, then peel off the materials from the coiling roller, or re-install the coiling roller with waste materials at a suitable position and then reverse the coiling roller. At this time, the unloading work of the materials can be completed.

[0068] The traditional waste edge coiling machine needs to be pre-disassembled for better unloading work. However, this working method has complex working steps and long working time. In addition, the coiling roller with waste materials is heavy, and a large amount of manpower cost is needed for unloading work, which brings inconvenience to people's use.

[0069] In addition, the existing waste edge conveying system adopts two-stage hoist, and a hoist motor drives a hopper to ascend. A waste edge coil is fed into the hopper from a coiler, a first-stage hoist pulls the hopper to a high position, and the hopper is overturned under the action of gravity, and the waste edge coil falls into a hopper of a second-stage hoist, and the hopper is ascended to the highest position under the action of the hoist, the hopper is overturned, and the waste edge coil falls into a waste edge collecting trolley.

[0070] The waste edge conveying system adopts the hoist to ascend, and the hopper returns to a low position by gravity after being emptied. In this process, blockage or overturning may occur due to track reasons. At the same time, the waste edge coil is generally heavy on one end and light on the other end, and in the hopper, due to the imbalance of the two sides, disordered placement may occur in the transfer process from the first stage to the second stage, and the edge wire may be hooked to the surrounding equipment and support.

[0071] It can be seen that the current waste edge coiling and conveying system still has many aspects to be improved.

[0072] The utility model provides a kind of on-line waste edge coiling and conveying collection system, can adapt to the fast rhythm production process requirement of double-line continuous galvanizing unit, greatly improve production efficiency.

[0074] In the embodiment of the present application, the online scrap edge coiling conveying and collecting system is used in a double-line continuous hot-dip galvanizing unit, which comprises a first continuous hot-dip galvanizing unit 100 and a second continuous hot-dip galvanizing unit 200 arranged in parallel along a first direction. In the embodiment of the present application, the double-line continuous hot-dip galvanizing unit is mainly taken as an example for illustration, and on the basis of the embodiment of the present application, the online scrap edge coiling conveying and collecting system can also be adaptively used in a three-line or even more continuous hot-dip galvanizing unit.

[0075] In the embodiment, the online scrap edge coiling conveying and collecting system mainly comprises a first scrap edge coiler 110, a second scrap edge coiler 210, a scrap edge guiding device 1, a first scrap edge conveyor 120, a second scrap edge conveyor 220 and a collecting device 300.

[0076] The present application will be described in detail below in combination with specific drawings and embodiments.

[0077] As shown in Figure 1 , two continuous hot-dip galvanizing units, i.e. a first continuous hot-dip galvanizing unit 100 and a second continuous hot-dip galvanizing unit 200, are arranged in the workshop, and the first continuous hot-dip galvanizing unit 100 and the second continuous hot-dip galvanizing unit 200 are arranged in parallel. For example, the first continuous hot-dip galvanizing unit 100 and the second continuous hot-dip galvanizing unit 200 both extend along a first direction.

[0078] The first scrap edge coiler 110 is arranged perpendicularly across the first continuous hot-dip galvanizing unit 100, and the second scrap edge coiler 210 is arranged perpendicularly across the second continuous hot-dip galvanizing unit 200. A scrap edge conveyor is arranged behind the scrap edge coiler, and the first scrap edge conveyor 120 and the second scrap edge conveyor 220 convey the scrap edge coils to a collecting device 300, for example, a trolley for collecting the scrap edge coils. The collecting device 300 is arranged in parallel with the first continuous hot-dip galvanizing unit 100 and the second continuous hot-dip galvanizing unit 200. For example, the trolley also extends along the first direction.

[0079] Specifically, the trolley can move along the first direction, and the collecting device 300 comprises at least one group of hoppers, the group of hoppers comprises a first hopper corresponding to the first scrap edge conveyor 120 and a second hopper corresponding to the second scrap edge conveyor 220, and the first hopper and the second hopper are arranged in parallel along the first direction.

[0080] The hopper group includes two groups, one group of hoppers is used as a main hopper group, and the other group of hoppers is used as a standby hopper group. Specifically, the trolley can include four hoppers, each of which can accommodate three to five scrap edge coils. The multi-hopper arrangement increases the collection capacity and reduces the hoisting frequency. When the trolley includes four hoppers, two hoppers can be configured for each scrap edge conveyor, one hopper is used to collect scrap edge coils at present, and the other hopper can be used as a standby hopper to ensure the continuity of the use of the entire online scrap edge coiling and conveying collection system.

[0081] As shown in Figure 2 , the disc shear of the first continuous hot galvanizing unit 100 cuts scrap edges online, the cut scrap edge wire passes through the corresponding scrap edge guide device 1, and then enters the first scrap edge coiler 110. The scrap edge coil coiled by the first scrap edge coiler 110 rolls onto the first scrap edge conveyor 120 and is transported to the hopper of the trolley by the conveyor belt and then is transported away.

[0082] As shown in Figure 3 , the disc shear of the second continuous hot galvanizing unit 200 cuts scrap edges online, the cut scrap edge wire passes through the corresponding scrap edge guide device 1, and then enters the second scrap edge coiler 210. The scrap edge coil coiled by the second scrap edge coiler 210 rolls onto the second scrap edge conveyor 220 and is transported to the hopper of the trolley by the conveyor belt and then is transported away.

[0083] Among them, for the first continuous hot galvanizing unit 100 and the second continuous hot galvanizing unit 200, in addition to sharing the collection device 300, the other scrap edge coiler, scrap edge guide device 1 and scrap edge conveyor are respectively provided for each set of continuous hot galvanizing unit.

[0084] For the first continuous hot galvanizing unit 100 and the second continuous hot galvanizing unit 200, in addition to the first scrap edge conveyor 120 and the second scrap edge conveyor 220 being different in length, the principles of their mechanisms are the same, and one set of them is taken as a typical structure in this application.

[0085] As shown in Figure 4 , in this embodiment, the scrap edge guide device 1 is located between the continuous hot galvanizing unit and the scrap edge coiler (as shown in Figure 2 , one scrap edge guide device 1 is arranged between the first continuous hot galvanizing unit 100 and the first scrap edge coiler 110, and as shown in Figure 3 , the other scrap edge guide device 1 is arranged between the second continuous hot galvanizing unit 200 and the second scrap edge coiler 210), which is vertically arranged and used for conveying the cut scrap edge to the corresponding scrap edge coiler (such as the first scrap edge coiler 110 in Figure 2 and the second scrap edge coiler 210 in Figure 3The second scrap edge coiler 210.

[0086] Specifically, the scrap edge guide device 1 has opposite upper and lower ends, the upper end is an open end for receiving the cut scrap edge, and the lower end is also an open end, the first scrap edge coiler 110 or the second scrap edge coiler 210 comprises an upper baffle 2 capable of opening or closing the lower end.

[0087] Taking the scrap edge guide device 1 and the first scrap edge coiler 110 as an example, the working process of the scrap edge guide device 1 and the first scrap edge coiler 110 is as follows:

[0088] When the first scrap edge coiler 110 is not started, the upper baffle 2 is closed, and the vertically falling scrap edge accumulates at the lower part of the scrap edge guide device 1;

[0089] When the first scrap edge coiler 110 is started, the upper baffle 2 is opened, and the scrap edge group falls into the first scrap edge coiler 110;

[0090] After each scrap edge coil is completed, the upper baffle 2 can be switched from the open state to the closed state under the drive of the power mechanism. Further, the baffle 15 is a flat steel plate, and the upper baffle 2 can be used to cut the scrap edge under the drive of the power mechanism. The upper baffle 2 can cut the falling scrap edge and re-form a storage space while being switched from the open state to the closed state under the drive of the power mechanism, ready for the next coiling cycle.

[0091] The power mechanism can comprise an upper baffle hydraulic cylinder 3 for controlling the extension and retraction of the upper baffle 2. When the power mechanism is in the form of a hydraulic cylinder, the stability and reliability of the upper baffle 2 during opening and closing can be ensured.

[0092] Taking the first scrap edge coiler 110 as an example, the first scrap edge coiler 110 can further comprise a rack 6, a guide plate 4 for guiding the scrap edge group introduced by the scrap edge guide device 1 to the core shaft 12 of the first scrap edge coiler 110, the core shaft 12 being used for threading on the scrap edge group for coiling, a guide plate hydraulic cylinder 5 for controlling the lifting and lowering of the guide plate 4, and a coiling bucket 8 in the form of an arc for shaping the scrap edge coil at the core shaft 12, a coiling bucket hydraulic cylinder 7 for controlling the turning of the coiling bucket 8.

[0093] Further, the first scrap edge coiler 110 can further comprise a press roller 11 for pressing on the scrap edge coil, and a press roller hydraulic cylinder 10 for controlling the lifting and lowering of the press roller 11.

[0094] In addition, the first scrap edge coiler 110 or the second scrap edge coiler 210 further comprises a guide plate 9; after the coiling bucket 8 is overturned, the scrap edge coil rolls along the guide plate 9 to the first scrap edge conveyor 120 and the second scrap edge conveyor 220.

[0095] Please refer to Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 As shown in Figure 5 , when the first scrap edge coiler 110 is in the first state, at this time, the coiling has not started, the upper baffle hydraulic cylinder 3 can control the upper baffle 2 to be in the extended closed state, and the scrap edge group does not enter the inside of the first scrap edge coiler 110; the guide plate 4 is in the falling state; the coiling bucket 8 is in the working position; the press roller 11 is in the raised state; and the mandrel 12 does not enter the inside of the first scrap edge coiler 110.

[0096] As shown in Figure 6 , when the first scrap edge coiler 110 is in the second state, that is, the first scrap edge coiler 110 enters the initial coiling state: the upper baffle hydraulic cylinder 3 controls the upper baffle 2 to switch from the extended closed state to the retracted open state, and the scrap edge group falls into the inside of the first scrap edge coiler 110; the guide plate hydraulic cylinder 5 controls the guide plate 4 to be raised; the coiling bucket 8 is in the working position; the press roller hydraulic cylinder 10 switches the press roller 11 from the raised state to the pressed-down state; and the mandrel 12 is inserted into the center of the scrap edge group.

[0097] As shown in Figure 7 , when the first scrap edge coiler 110 is in the third state, that is, the first scrap edge coiler 110 enters the coiling state: at this time, the upper baffle hydraulic cylinder 3 controls the upper baffle 2 to remain in the retracted open state, and the scrap edge falls into the inside of the coiler; the guide plate hydraulic cylinder 5 controls the guide plate 4 to switch from the raised state to the retracted state; the coiling bucket 8 is in the working position; at this time, the press roller 11 is in the pressed-down state and remains tightly attached to the scrap edge coil.

[0098] As shown in Figure 8 , when the first scrap edge coiler 110 is in the fourth state, that is, the first scrap edge coiler 110 enters the uncoiling state: after the coiling is completed, the upper baffle hydraulic cylinder 3 controls the upper baffle 2 to switch from the retracted state to the extended state, and realizes the cutting of the scrap edge during the extension; the press roller hydraulic cylinder 10 switches the press roller 11 from the pressed-down state to the raised state; the mandrel 12 is extracted; the coiling bucket 8 is overturned, and the scrap edge coil rolls along the guide plate 9 to the first scrap edge conveyor 120.

[0099] Since the second scrap edge coiler 210 and the scrap edge guide device 1 are the same as the first scrap edge coiler 110 and the scrap edge guide device 1 in cooperation and the principle of realizing the coiling of the scrap edge, the present application will not be described here.

[0100] like Figure 9 As shown, in one embodiment, the first waste edge conveyor 120 or the second waste edge conveyor 220 includes: a conveying plate for cyclically conveying the waste edge roll; and a power mechanism for driving the conveying plate to rotate cyclically and convey the waste edge roll to the collection device 300.

[0101] The first waste edge conveyor 120 and the second waste edge conveyor 220 are very similar in composition, structure and function. In this application, the first waste edge conveyor 120 will be the main focus of the description.

[0102] The first waste edge conveyor 120 may include a conveyor plate and a power mechanism. Specifically, the conveyor plate may be a conveyor scale plate 14, which can avoid problems such as side tipping, jamming, and tangling, thus improving production stability. The conveyor scale plate 14 may include:

[0103] The power mechanism may include a conveyor motor, a conveyor drive wheel 16, and a conveyor driven wheel 13. The conveyor drive wheel 16 and the conveyor driven wheel 13 may be located at opposite ends of the first waste edge conveyor 120. Specifically, the motor and the conveyor driven wheel 13 may be located near the first waste edge coiler 110, and the conveyor drive wheel 16 may be located near the collection device 300, such as a trolley.

[0104] In use, the motor drives the conveyor drive wheel 16 to rotate, and with the cooperation of the conveyor driven wheel 13, it drives the conveyor plate to rotate in a cycle, conveying the waste edge rolls to the collection device 300 at the upper end, such as a trolley for collecting waste edge rolls.

[0105] Furthermore, the conveyor plate of the first waste edge conveyor 120 may include a horizontal section and a ramp section. To prevent the waste edge roll from rolling downhill under gravity when it is conveyed to the ramp section, the first waste edge conveyor 120 may also include a baffle 15 disposed on the surface of the conveyor plate to stop the waste edge roll.

[0106] Specifically, the baffle 15 includes multiple baffles 15, which are disposed on the surface of the conveyor plate at predetermined intervals. The spacing between two adjacent baffles 15 and the height of a single baffle 15 can be set according to the size of the waste roll. Theoretically, any structure and size that can reliably stop and limit the waste roll and prevent it from slipping on the slope section is applicable to this application.

[0107] The main difference between the second waste edge conveyor 220 and the first waste edge conveyor 120 is the length of the conveyor plate. The second waste edge conveyor 220 may only include the ramp section, and other components, structures and functions can be referred to the first waste edge conveyor 120. This application will not elaborate on them in detail here.

[0108] As Figure 10 , Figure 11 and Figure 12 indicated, the collecting device 300 provided in the embodiments of the present application for collecting the scrap edge roll can be in the form of a trolley.

[0109] The trolley can include a track 21, a trolley body 18, a driving motor, a trolley driving wheel 19, a trolley transmission wheel 23, a scrap hopper 17, a chain 22, etc.

[0110] The scrap hoppers 17 are arranged along the first direction and are used to accommodate the scrap edge rolls. The trolley body 18 can include four hopper positions and can be used to accommodate up to four scrap hoppers 17. The trolley body 18 has opposite front and rear sides along the first direction, and the front and rear sides of the trolley body 18 can be provided with the chain 22, which is used for transmission to drive the trolley body 18 to move.

[0111] The trolley driving wheel 19 can be driven by the driving motor to provide driving force for the movement of the trolley body 18.
