Description

Technical Field

[0001] This utility model relates to the technical field of steel strip processing equipment, specifically to a sample-inspection type waste guiding device and a strip steel production line. Background Technology

[0002] During the rolling mill production process, scrap steel strip that is contaminated, defective, or affects appearance and performance needs to be cut and transferred to the scrap recycling area. This process is usually diverted by a rotating guide plate. When the guide plate is open, the scrap steel strip slides down into the scrap hopper due to gravity via the inclined guide plate. Due to the roughness of the guide plate surface material and the influence of the guide plate placement angle, scrap often gets stuck and blocked, preventing it from falling. This can lead to equipment damage or downtime, requiring manual cleaning, increasing safety hazards and reducing production efficiency. Utility Model Content

[0003] This utility model provides a sample-inspection waste guiding device and a strip steel production line, aiming to solve the problems in the prior art.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0005] A sample-inspection type waste guiding device includes a first material conveying platform, a first flipping mechanism, a second flipping mechanism, a baffle support, and a sampling mechanism. The first material conveying platform is fixedly inclined. The first flipping mechanism and the second flipping mechanism are respectively installed below the first material conveying platform, with the second flipping mechanism located below the first flipping mechanism. The first and second flipping mechanisms can be flipped up and down and positioned. The baffle support is located above the area between the first and second flipping mechanisms. The first flipping mechanism can be flipped so that its discharge end is above the baffle support. The sampling mechanism is distributed below the second flipping mechanism.

[0006] The beneficial effects of this utility model are: during operation, different operating states can be freely switched by flipping the first flipping mechanism and the second flipping mechanism, for example:

[0007] Strip conveying status: The first flipping mechanism flips upward until its discharge end connects with the baffle bracket. Then, the first material conveying platform and the first flipping mechanism are used to send the strip to the belt conveyor, and the belt conveyor then conveys the strip to the set position.

[0008] Waste collection status: The first flipping mechanism flips downwards, and the second flipping mechanism also flips downwards at the same time. The waste falls through the material platform, the first flipping mechanism, and the second flipping mechanism for recycling.

[0009] Waste material sampling inspection status: Flipping mechanism one and flipping mechanism two flip up to be flush, so that the waste material is sent to the sampling inspection mechanism for sampling inspection.

[0010] In this invention, the two different working states of the two flip-plate mechanisms can be freely combined, and the waste collection and sampling inspection process is automated through hydraulic control, which is convenient and low in cost.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the first flipping mechanism and / or the second flipping mechanism are flipping roller mechanisms.

[0013] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable. The strip steel passes through the surface of the flipping roller mechanism, resulting in low frictional resistance and smooth passage. This significantly reduces jamming and blockage problems, improves work efficiency, and saves labor costs.

[0014] Furthermore, each of the aforementioned flip-type roller mechanisms includes a base plate and multiple sets of roller assemblies. The base plate is inclined and can be flipped up and down and positioned. The multiple sets of roller assemblies are evenly spaced and arranged side by side on the base plate along a direction perpendicular to the material conveying direction.

[0015] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable. The strip steel passes through the surface of multiple sets of roller assemblies, resulting in low frictional resistance and smooth passage. This significantly reduces jamming and blockage problems, improves work efficiency, and saves labor costs.

[0016] Furthermore, a tilting cylinder is installed below the base plate, which is rotated up and down, and the telescopic end of the tilting cylinder is rotatably connected to the corresponding part of the base plate.

[0017] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable. The bottom plate can be flipped up and down by using the extension and retraction of the tilting cylinder, so as to achieve free switching between different working states and make the operation more convenient.

[0018] Furthermore, the multiple sets of roller assemblies include multiple rollers, and the multiple rollers in each set of roller assemblies are evenly spaced and arranged side by side along the material conveying direction. The rollers are distributed parallel to the base plate, and each roller can rotate about its own axis. The axis of the roller is perpendicular to the material conveying direction.

[0019] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable. The strip steel passes through the surface of multiple rollers, resulting in low frictional resistance and smooth passage. This significantly reduces jamming and blockage problems, improves work efficiency, and saves labor costs.

[0020] Furthermore, multiple rollers in two adjacent sets of roller assemblies are distributed alternately at intervals.

[0021] The advantages of adopting the above-mentioned further scheme are that the structure is simple, the design is reasonable, the rollers in the multiple roller assemblies are reasonably distributed, and the strip steel or scrap is transported smoothly.

[0022] Furthermore, it also includes a second material conveying platform, which is inclined and fixedly installed between the sampling inspection mechanism and the second flipping mechanism. The second flipping mechanism can be flipped to its lower end to connect with the second material conveying platform or flipped to be below the second material conveying platform.

[0023] The advantages of adopting the above-mentioned further solution are that the structure is simple, the material conveying platform 2 is set up in a more reasonable way, and the waste material to be inspected can be sent to the inspection agency, making the material feeding convenient.

[0024] Furthermore, the first material conveying platform and / or the second material conveying platform are both fixed roller mechanisms.

[0025] The advantages of adopting the above-mentioned further solution are that the structure is simple and the design is reasonable. The strip steel passes through the surface of the fixed roller mechanism, resulting in low frictional resistance and smooth passage. This significantly reduces jamming and blockage problems, improves work efficiency, and saves labor costs.

[0026] This utility model also relates to a strip steel production line, including a belt conveyor and a waste collection mechanism, and further including a sampleable waste guiding device as described in any one of the claims, wherein the belt conveyor is horizontally installed at the discharge end of the baffle bracket; the waste collection mechanism is located below the first and second flipping mechanisms, and the sampling mechanism is located on one side of the waste collection mechanism.

[0040] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0041] Example 1

[0042] like Figures 1 to 5 As shown, this embodiment provides a sample-inspection type waste guiding device, including a material conveying platform 4, a flipping mechanism 5, a second flipping mechanism 6, a baffle bracket 7, and a sampling mechanism 11. The material conveying platform 4 is fixedly inclined. The first flipping mechanism 5 and the second flipping mechanism 6 are respectively installed below the material conveying platform 4, and the second flipping mechanism 6 is located below the first flipping mechanism 5. The first flipping mechanism 5 and the second flipping mechanism 6 can be flipped up and down and positioned. The baffle bracket 7 is located above the area between the first flipping mechanism 5 and the second flipping mechanism 6. The first flipping mechanism 5 can be flipped so that its discharge end is above the baffle bracket 7. The sampling mechanism 11 is distributed below the second flipping mechanism 6.

[0043] During operation, different operating states can be freely switched by flipping mechanism 5 and flipping mechanism 6, for example:

[0044] Strip conveying status: The flipping mechanism 5 flips upward until its discharge end connects with the baffle bracket 7. Then, the strip is sent to the belt conveyor by the material conveying platform 4 and the flipping mechanism 5. The belt conveyor then transports the strip to the set position.

[0045] Waste collection status: The first flipping mechanism 5 flips downwards, and the second flipping mechanism 6 also flips downwards. The waste falls through the material platform 4, the first flipping mechanism 5 and the second flipping mechanism 6 for recycling.

[0046] Waste material sampling inspection status: Material platform 1 4, flipping mechanism 1 5 and flipping mechanism 2 6 flip up to connect end to end in sequence to send the waste material to sampling inspection mechanism 11 for sampling inspection.

[0047] Preferably, this embodiment also includes a support 1, and the material conveying platform 4 is fixedly mounted on the support 1 by means of a bracket.

[0048] In addition, the aforementioned sampling inspection agency 11 is a sampling inspection station, and the scrap steel strips are inspected manually after being sent to the sampling inspection station.

[0049] This embodiment also includes a control system (i.e., a controller in the prior art), which controls the operation of the entire equipment. The purpose of the sampling inspection is to manually check whether the cut ends of the scrap steel strip are neat and complete, in order to determine whether the shears of the shearing machine need to be replaced or repaired. The specific operation is as follows: after the scrap is sent to the sampling inspection mechanism 11, the manual inspection is conducted to check whether the cut ends of the scrap steel strip are neat and complete.

[0050] It should be noted that the sampling inspection of steel strip scrap can be carried out by setting up periodic sampling inspection through the control system, or by manually operating the control system as needed. The specific design depends on the requirements.

[0051] In this embodiment, the two different working states of the two flip-plate mechanisms can be freely combined. The waste collection and sampling inspection process is automated through hydraulic control, which is convenient and low in cost.

[0052] Example 2

[0053] Based on Embodiment 1, in this embodiment, the flipping mechanism 5 and / or the flipping mechanism 6 are flipping roller mechanisms.

[0054] The solution has a simple structure and reasonable design. The strip passes over the surface of the flipping roller mechanism, which has low frictional resistance and can achieve smooth passage. This significantly reduces jamming and blockage problems, improves work efficiency, and saves labor costs.

[0055] Alternatively, the aforementioned flipping mechanism 5 and flipping mechanism 6 can also be directly designed as inclined flat plate structures. However, in this design, the friction between the strip steel and strip steel scrap and the flipping mechanism 5 and flipping mechanism 6 is relatively large, which can easily lead to jamming and blockage.

[0056] Example 3

[0057] Based on Embodiment 2, in this embodiment, each of the flipping roller mechanisms includes a base plate 12 and multiple sets of roller assemblies. The base plate 12 is inclined and can be flipped up and down and positioned. The multiple sets of roller assemblies are evenly spaced and arranged side by side on the base plate 12 along a direction perpendicular to the material conveying direction.

[0058] The solution has a simple structure and reasonable design. The strip passes over the surface of multiple sets of roller assemblies, resulting in low frictional resistance and smooth passage. This significantly reduces jamming and blockage, improves work efficiency, and saves labor costs.

[0059] Example 4

[0060] Based on embodiment 3, in this embodiment, a tilting cylinder 2 is installed below the base plate 12, which is tilted up and down, and the telescopic end of the tilting cylinder 2 is rotatably connected to the corresponding part of the base plate 12.

[0061] The scheme has a simple structure and reasonable design. It uses the extension and retraction of the tilting cylinder 2 to realize the up and down tilting of the base plate 12, so as to achieve free switching between different working states and make the operation more convenient.

[0062] Based on the above scheme, the specific structure of the flipping mechanism 5 is as follows: the base plate 12 is installed on the support 1 through the bracket 3, and the corresponding part of the base plate 12 is rotatably connected to the bracket 3, i.e., hinged; the telescopic end of the corresponding flipping cylinder 2 is rotatably connected to the discharge end of the base plate 12, i.e. hinged, and the end of the flipping cylinder 2 is rotatably connected to the bracket 3.

[0063] The specific structure of the above-mentioned flipping mechanism 6 is as follows: the base plate 12 is installed on the support 1 through the bracket 3, and the feeding end of the base plate 12 is rotatably connected to the bracket 3, i.e., hinged; the telescopic end of the corresponding flipping cylinder 2 is rotatably connected to the discharge end of the base plate 12, i.e. hinged, and the end of the flipping cylinder 2 is rotatably connected to the bracket 3.

[0064] Example 5

[0065] Based on any one of Embodiments 3 to 4, in this embodiment, the multiple sets of roller assemblies include multiple rollers 8. The multiple rollers 8 in each set of roller assemblies are evenly spaced and arranged side by side along the material conveying direction. The rollers 8 are distributed parallel to the base plate 12 and can rotate around their own axis. The axis of the roller 8 is perpendicular to the material conveying direction.

[0066] The solution has a simple structure and reasonable design. The strip passes through the surfaces of multiple rollers 8, resulting in low frictional resistance and smooth passage. This significantly reduces jamming and blockage problems, improves work efficiency, and saves labor costs.

[0067] Based on the above scheme, multiple pairs of fixing plates are evenly spaced and fixedly installed on each base plate 12, and the multiple pairs of fixing plates are distributed perpendicular to the base plate 12; multiple rollers 8 in each roller assembly are distributed between the corresponding pair of fixing plates and are rotatably connected to the pair of fixing plates.

[0068] Example 6

[0069] Based on Embodiment 5, in this embodiment, multiple rollers 8 in two adjacent sets of roller assemblies are distributed alternately at intervals.

[0070] The solution has a simple structure and a reasonable design. The rollers 8 in the multiple roller assemblies are distributed in a reasonable manner to ensure the smooth conveying of strip steel or scrap.

[0071] Based on the above scheme, the alternating distribution of multiple rollers 8 in two adjacent sets of roller assemblies means that in two adjacent sets of roller assemblies, multiple rollers 8 in one set of roller assemblies are evenly spaced, and multiple rollers 8 in the other set of roller assemblies are evenly spaced, and the gaps between multiple rollers 8 in the other set of roller assemblies and multiple rollers 8 in one set of roller assemblies are respectively opposite.

[0072] Example 7

[0073] Based on the above embodiments, this embodiment also includes a material conveying platform 2 9, which is inclinedly and fixedly installed between the sampling mechanism 11 and the flipping mechanism 2 6. The flipping mechanism 2 6 can be flipped so that its lower end connects with the material conveying platform 2 9 or flipped to be below the material conveying platform 2 9.

[0074] The scheme has a simple structure and the material conveying platform 29 is set up in a reasonable way, which can send the waste material to be inspected to the inspection agency 11, making the material feeding convenient.

[0075] Example 8

[0076] Based on Embodiment 7, in this embodiment, the material conveying platform 4 and / or the material conveying platform 9 are fixed roller mechanisms.

[0077] The solution has a simple structure and reasonable design. The strip passes over the surface of the fixed roller mechanism, resulting in low frictional resistance and smooth passage. This significantly reduces jamming and blockage, improves work efficiency, and saves labor costs.

[0078] Each of the above-mentioned fixed roller mechanisms includes a base plate 12 and multiple sets of roller assemblies. The base plate 12 is obliquely fixed on the support 1. The multiple sets of roller assemblies are evenly spaced and arranged side by side on the base plate 12 along a direction perpendicular to the material conveying direction.

[0079] In addition, the multiple sets of roller assemblies include multiple rollers 8. The multiple rollers 8 in each set of roller assemblies are evenly spaced and arranged side by side along the material conveying direction. The rollers 8 are distributed parallel to the base plate 12 and can rotate around their own axis. The axis of the roller 8 is perpendicular to the material conveying direction.

[0080] Based on the above scheme, multiple pairs of fixing plates are evenly spaced and fixedly installed on each base plate 12, and the multiple pairs of fixing plates are distributed perpendicular to the base plate 12; multiple rollers 8 in each roller assembly are distributed between the corresponding pair of fixing plates and are rotatably connected to the pair of fixing plates.

[0081] In addition, the base plates 12 of the material conveying platform 1 4 and the material conveying platform 2 9 are respectively fixedly and inclined on the support 1, and the base plate 12 of the material conveying platform 2 9 is fixedly and inclined on the support 1 by the bracket 2 10.

[0082] Alternatively, the aforementioned material handling platforms 1-4 and 2-9 can also be inclined flat plate structures. However, this scheme results in greater friction between the strip steel and strip steel scrap and material handling platforms 1-4 and 2-9, which can easily lead to jamming and blockage.

[0083] Example 9

[0084] Based on the above embodiments, this embodiment also provides a strip steel production line, including a belt conveyor 13 and a waste collection mechanism 14, and also includes a sampleable waste guiding device as described above. The belt conveyor 13 is horizontally installed at the discharge end of the baffle bracket 7; the waste collection mechanism 14 is located below the flipping mechanism 5 and the flipping mechanism 6, and the sampling mechanism 11 is located on one side of the waste collection mechanism 14.

[0085] Based on the above scheme, the belt conveyor 13 is horizontally fixed on the support 1. It adopts the belt conveyor in the prior art, so its specific structure and principle will not be described in detail here.

[0086] In addition, the waste collection mechanism 14 is located below the support 1.

[0087] This embodiment also provides a strip steel production line in which the two different working states of the two flipping mechanisms can be freely combined. The waste collection and sampling inspection process is automated through hydraulic control. At the same time, the strip steel passes over the surface of the inertial wheel, with low frictional resistance, which can achieve smooth passage, significantly reducing jamming and blockage problems, improving work efficiency and saving labor costs.

[0088] Example 10

[0089] Based on Example 9, in this example, the upper end of the waste collection mechanism 14 has a funnel-shaped structure.

[0090] The scheme has a simple structure and the shape of the upper part of the waste collection mechanism 14 is reasonably designed to facilitate the collection of waste and prevent waste from falling outside the waste collection mechanism 14.

[0091] The working principle of this utility model is as follows:

[0092] Strip conveying status: The flipping mechanism 5 flips upward until its discharge end connects with the baffle bracket 7. Then, the strip is sent to the belt conveyor 13 by the material conveying platform 4 and the flipping mechanism 5. The belt conveyor 13 then conveys the strip to the set position.

[0093] Waste collection status: The first flipping mechanism 5 flips downwards, and the second flipping mechanism 6 also flips downwards. The waste falls through the material platform 4, the first flipping mechanism 5 and the second flipping mechanism 6 for recycling.

[0094] Waste material sampling inspection status: Flipping mechanism 1 5 and flipping mechanism 2 6 flip to be flush, so as to send the waste material to sampling inspection mechanism 11 for sampling inspection.

[0095] It should be noted that all electronic components involved in this utility model adopt existing technology, and all the above-mentioned components are electrically connected to the controller, and the control circuit between the controller and each component is existing technology.
