Description

Technical Field

[0001] This utility model relates to the field of sheet metal uncoiling technology, specifically to a sheet metal uncoiling device that facilitates the loading of sheets. Background Technology

[0002] Sheet metal is a flat material with a certain thickness and width, widely used in construction, furniture manufacturing, automotive industry, electronic products and many other fields. For ease of use, some sheet metal is rolled into coils for storage and transportation. However, when used later, uncoiling equipment is needed to rewind the coils. For example, narrow strip steel coils are laid horizontally after production and have a relatively light overall weight. They are then uncoiled using an uncoiling machine during subsequent processing.

[0003] For example, Chinese patent application CN118950744A discloses an uncoiler, including a machine body; a mandrel rotatably mounted on the machine body, and an expansion sleeve arranged on the mandrel; a feeding trolley for placing the coiled material; and a collision detection assembly, including a grounding module mounted on the machine body, an anti-collision paddle mounted on the mandrel, an elastic paddle mounted on the feeding trolley, and a detection module connected to the elastic paddle; the detection module is configured to issue a collision warning when the elastic paddle, the coiled material, the anti-collision paddle, the mandrel, the machine body, and the grounding module form a circuit.

[0004] However, when using this uncoiler, it is necessary to use overhead cranes or other equipment with ropes to lift the coil and then place it sideways on the loading trolley. The loading speed is slow, making it unsuitable for workshops without overhead cranes or other equipment.

[0005] Based on this, the present invention designs an easy-to-unwind sheet metal device to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a sheet unwinding device that facilitates the winding of sheets.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A sheet metal uncoiling device for easy loading includes a support frame, a tensioning uncoiling device, a feeding and turning device, and a follow-up lifting device.

[0009] The bracket is equipped with a tensioning and uncoiling device for tensioning and driving the sheet metal to uncoil, a feeding and turning device for driving the tensioning and uncoiling device to turn over to facilitate feeding, and a follow-up lifting device for supporting and placing the sheet metal to be uncoiled. The tensioning and uncoiling device and the feeding and turning device are connected.

[0010] The follow-up lifting device includes a sliding avoidance component for placing the uncoiled sheet and avoiding it during uncoiling, and an auxiliary tensioning component for facilitating the movement of the sheet during tensioning of the tensioning uncoiling device. The sliding avoidance component is connected to the bracket and the tensioning uncoiling device, and the auxiliary tensioning component is installed on the sliding avoidance component.

[0011] Furthermore, the bracket includes a base plate and two mounting seats, which are symmetrically arranged front and back and fixedly installed on the upper part of the base plate.

[0012] Furthermore, the tensioning and unwinding device includes a tensioning component and a driving component. The driving component is rotatably mounted between two mounting seats. The lower end of the driving component is connected to the feeding and turning device. The tensioning component is mounted on the right end of the driving component, and the outer side of the tensioning component is connected to the sliding avoidance component.

[0013] Furthermore, the output end of the drive component is connected to the tensioning component, and the drive component drives the tensioning component to perform tensioning and rotation.

[0014] Furthermore, the feeding and turning device includes a hydraulic cylinder, a rotating plate, and a rotating seat. The hydraulic cylinder is fixedly mounted on the rotating plate, the rotating plate is rotatably mounted between two mounting seats, the output end of the hydraulic cylinder is rotatably connected to the rotating seat, and the rotating seat is fixedly mounted on the lower end of the drive assembly.

[0015] Furthermore, the sliding avoidance assembly includes a sliding plate and two follower avoidance components. The two follower avoidance components are symmetrically arranged front and rear. The sliding plate is slidably mounted on the outside of the tensioning assembly, and the two follower avoidance components are mounted on the side of the sliding plate facing the driving assembly. The two follower avoidance components are connected to the mounting base.

[0016] Furthermore, the follow-up avoidance component includes a roller frame, a roller, and a track plate.

An arc-shaped groove for use with the roller is provided on the track plate. The distance between the right end of the arc-shaped groove and the axis of the drive assembly is less than the distance between the upper end of the arc-shaped groove and the axis of the drive assembly.

[0017] Furthermore, there are two auxiliary tensioning components arranged symmetrically on the top and bottom. The two auxiliary tensioning components are installed on the side of the sliding plate away from the driving component. The auxiliary tensioning components include a support base and multiple universal balls.

At the same time, the setting of the sliding avoidance component allows the auxiliary tensioning component to detach from the material during rotation, avoiding the contact between the material and the auxiliary tensioning component during uncoiling, which would cause scratch damage during uncoiling.

[0019] 2. The support base and universal ball bearings allow the sheet material to be uncoiled to move easily under the action of the universal ball bearings during the tensioning process, which helps the sheet material to be uncoiled to remain concentric with the tensioning components and improves the stability of the tensioning process.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-5 A sheet metal uncoiling device for easy loading includes a support 1, a tensioning uncoiling device 2, a feeding and turning device 3, and a follow-up lifting device 4.

[0030] The bracket 1 is equipped with a tensioning and uncoiling device 2 for tensioning and driving the sheet to uncoil, a feeding and turning device 3 for driving the tensioning and uncoiling device 2 to turn over to facilitate feeding, and a follow-up lifting device 4 for supporting and placing the sheet to be uncoiled. The tensioning and uncoiling device 2 and the feeding and turning device 3 are connected.

[0031] The follow-up lifting device 4 includes a sliding avoidance component 41 for placing the uncoiled sheet and avoiding it during uncoiling, and an auxiliary tensioning component 42 for assisting the tensioning uncoiling device 2 in facilitating the movement of the sheet during tensioning. The sliding avoidance component 41 is connected to the bracket 1 and the tensioning uncoiling device 2, and the auxiliary tensioning component 42 is installed on the sliding avoidance component 41.

[0032] When the easy-to-load sheet uncoiling device is in normal use, start the feeding and turning device 3. The feeding and turning device 3 drives the tensioning and uncoiling device 2 to rotate upward. Use feeding equipment such as a forklift to place the sheet to be uncoiled on the auxiliary tensioning component 42. Start the tensioning and uncoiling device 2 to tension and fix the sheet to be uncoiled. The auxiliary tensioning component 42 assists in the tensioning process. Start the feeding and turning device 3 again to drive the tensioning and uncoiling device 2 to rotate in the opposite direction to the right. At the same time, the sliding avoidance component 41 drives the auxiliary tensioning component 42 to disengage from the support of the sheet to be uncoiled. Through the setting of the feeding and turning device 3, the sheet to be uncoiled can be fed from top to bottom, without the need to use overhead cranes, cranes or other equipment with ropes to feed from the side, which improves the feeding speed. It is suitable for uncoiling lightweight coils such as narrow steel coils. At the same time, the setting of the sliding avoidance component 41 allows the auxiliary tensioning component 42 to disengage from the sheet during rotation, avoiding contact between the sheet and the auxiliary tensioning component 42 during uncoiling, which may cause scratch damage.

[0033] The bracket 1 includes a base plate 11 and two mounting seats 12. The two mounting seats 12 are symmetrically arranged and fixedly installed on the upper end of the base plate 11. The tensioning uncoiling device 2 and the feeding and turning device 3 are installed between the two mounting seats 12. The sliding avoidance component 41 is connected to the mounting seat 12.

[0034] The tensioning and unwinding device 2 includes a tensioning component 21 and a drive component 22. The drive component 22 is rotatably mounted between two mounting bases 12. The lower end of the drive component 22 is connected to the feeding and turning device 3. The tensioning component 21 is mounted on the right end of the drive component 22. The outer side of the tensioning component 21 is connected to the sliding avoidance component 41.

[0035] The output end of the drive component 22 is driven to the tension component 21. The drive component 22 drives the tension component 21 to perform tensioning and rotation. Both the tension component 21 and the drive component 22 adopt mature technologies in the field. For example, the tension component 21 adopts the part named "support shaft and tensioning mechanism" in the patent with publication number CN112222225A, and the drive component 22 adopts the part named "frame and rotating shaft" in the patent with publication number CN112222225A.

[0036] The feeding and turning device 3 includes a hydraulic cylinder 31, a rotating plate 32 and a rotating seat 33. The hydraulic cylinder 31 is fixedly installed on the rotating plate 32, and the rotating plate 32 is rotatably installed between two mounting seats 12. The output end of the hydraulic cylinder 31 is rotatably connected to the rotating seat 33, and the rotating seat 33 is fixedly installed at the lower end of the drive assembly 22.

[0037] The sliding avoidance component 41 includes a sliding plate 411 and two follower avoidance components. The two follower avoidance components are symmetrically arranged front and back. The sliding plate 411 is slidably installed on the outside of the tensioning component 21. The two follower avoidance components are installed on the side of the sliding plate 411 facing the drive component 22. The two follower avoidance components are connected to the mounting base 12.

[0038] The follow-up avoidance component includes a roller frame 412, a roller 413, and a track plate 414. The roller frame 412 is fixedly installed on the side of the sliding plate 411 facing the drive assembly 22. The roller 413 is rotatably installed on the end of the roller frame 412 away from the sliding plate 411. The roller 413 is in rolling connection with the track plate 414. The track plate 414 is fixedly installed on the upper end of the mounting base 12. An arc-shaped groove is opened on the track plate 414 to cooperate with the roller 413. The distance between the right end of the arc-shaped groove and the axis of the drive assembly 22 is less than the distance between the upper end of the arc-shaped groove and the axis of the drive assembly 22.

[0039] Two auxiliary tensioning components 42 are symmetrically arranged vertically. The two auxiliary tensioning components 42 are installed on the side of the sliding plate 411 away from the drive component 22. The auxiliary tensioning component 42 includes a support base 421 and a plurality of universal balls 422. The support base 421 is fixedly installed on the sliding plate 411, and the plurality of universal balls 422 are evenly arranged front and back and rolled and embedded in the support base 421.

[0040] When the sheet metal uncoiling device is in normal use, the hydraulic cylinder 31 is activated, which pushes the rotating seat 33. The rotating seat 33 drives the drive assembly 22 and the tensioning assembly 21 to rotate, so that the tensioning assembly 21 faces upward. The sheet metal to be uncoiled is placed on the universal ball bearing 422 using the feeding equipment. The drive assembly 22 is activated, which drives the tensioning assembly 21 to tension and fix the sheet metal to be uncoiled. During the tensioning process, the sheet metal to be uncoiled rolls along the universal ball bearing 422 to complete the centering movement. The hydraulic cylinder 31 is activated again, which drives the drive assembly 22 and the tensioning assembly 21 to rotate, so that the tensioning assembly 21 faces to the right. At the same time, the roller 413 rolls along the slide rail of the track plate 414. The track plate 414 drives the roller frame 412 and the roller 413 to move. The sheet metal slides along the tensioning assembly 21 toward the drive assembly 22, causing the universal ball bearing 422 to disengage from the support of the sheet metal to be uncoiled. The drive assembly 22 is then activated to rotate the tensioning assembly 21 and begin uncoiling. During uncoiling, the sheet metal does not contact the universal ball bearing 422. The sliding plate 411 is driven to slide during rotation by the track plate 414, causing the universal ball bearing 422, which supports the sheet metal, to disengage from the sheet metal during uncoiling to avoid scratches and damage. The support base 421 and the universal ball bearing 422 allow the sheet metal to be uncoiled to move easily under the action of the universal ball bearing 422 during the tensioning process, making it easier for the sheet metal to be uncoiled to remain concentric with the tensioning assembly 21 and improving the stability of the tensioning process.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
