[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] Reference Figure 1-5 , which is the first embodiment of the present utility model, provides a feeding device for shield cover production, which includes a fixed base plate 1, a material limiting component 2 and a material driving component 3. The material limiting component 2 and the material driving component 3 are both fixed to the middle of the top of the fixed base plate 1, and the movable ends of the material limiting component 2 are located on both sides of the top of the fixed base plate 1. A material channel for limiting the movement of raw materials is formed between the material limiting component 2 and the material driving component 3;

[0031] The material driving assembly 3 includes two lower supports 31 and an upper support 32, and the driving end of the upper support 32 is located in the middle between the two lower supports 31. A raw material running cavity is formed between the upper side of the movable ends of the two lower supports 31 and the lower side of the driving end of the upper support 32.

[0032] The pressure roller 328 can rotate with the rotating shaft 323 as the rotating point. When the rotating shaft 323 rotates, the distance between the pressure roller 328 and the supporting roller 312 can be adjusted. It can be adaptively adjusted according to the thickness of the metal bar to achieve the pressure and conveyance of metal bars of different thicknesses. At the same time, the metal bar can be installed by simply inserting it between the opposite surfaces of the pressure roller 328 and the supporting roller 312, which is convenient to use.

[0033] The lower support member 31 includes an axis plate 311 welded to the top of the fixed base plate 1, and a support shaft 313 is rotatably installed between the opposite surfaces of the two axis plates 311 through bearings. A roller 312 is sleeved on the middle part of the outer wall of the support shaft 313, and a driving motor 314 for driving the support shaft 313 to rotate is installed on one axis plate 311, and the driving end of the driving motor 314 is connected to the shaft end of the support shaft 313.

[0034] The upper support 32 includes two T-shaped plates 321 welded to the top of the fixed base plate 1, and a U-shaped frame 322 is welded between the tops of the two T-shaped plates 321. Two rotating bars 326 are rotatably installed inside the U-shaped frame 322, and a pressure shaft 327 is rotatably installed between the opposite surfaces of the two rotating bars 326. A pressure roller 328 is sleeved on the middle part of the outer wall of the pressure shaft 327. A driving motor 2 329 is installed on the inner side of one rotating bar 326, and a belt transmission assembly 3210 is installed between the driving end of the driving motor 2 329 and one end of the pressure shaft 327. The belt transmission assembly 3210 consists of two pulleys and a belt installed between the two pulleys. The belt transmission assembly 3210 is an existing mature technology, so it will not be described in detail.

[0035] A rotating shaft 323 is rotatably mounted in the inner cavity of the U-shaped frame 322 via a bearing, and two rotating bars 326 are respectively sleeved on both ends of the rotating shaft 323 .

[0036] V-shaped spring members 325 are installed on the front and rear sides of the inner wall of the U-shaped frame 322, and only one side of the V-shaped spring member 325 is fixed to the inner wall of the U-shaped frame 322. The end of the V-shaped spring member 325 close to the rotating bar 326 is in contact with the outward side of the rotating bar 326. When the rotating shaft 323 drives the pressure roller 328 to rotate clockwise, the rotating bar 326 will resist and compress one end of the V-shaped spring member 325. Under the reverse elastic pressure of the V-shaped spring member 325, it will be applied to the rotating bar 326, applying a downward pressure to the pressure roller 328, so that the pressure roller 328 is pressed more tightly against the top of the metal bar, thereby increasing the friction between the pressure roller 328 and the roller 312, which is more conducive to the stable conveying of the metal bar.

[0037] Both ends of the rotating bar 326 are semicircular in shape, and triangular blocks 324 are welded to the front and rear sides of one side of the U-shaped frame 322, and the inclined surface of the triangular block 324 is close to one side of the rotating bar 326. The inclined surface of the triangular block 324 fits the bottom of the rotating bar 326 and is arranged in a parallel state. Guide rails 21 are installed on both sides of the top of the fixed base plate 1, and sliding grooves sliding with the guide rails 21 are provided on both sides of the bottom of the translation bar 23.

[0038] The V-shaped spring member 325 will elastically compress the rotating bar 326 so that the bottom edge of the rotating bar 326 fits into the inclined surface of the triangular block 324, and the triangular block 324 plays a role in resisting and limiting the rotating bar 326 to ensure that the pressure roller 328 is in the middle between the two lower supporting members 31, limiting the position of the lowest point of the pressure roller 328, avoiding the pressure roller 328 from moving too downward and colliding, and also helping to improve the stability of the device operation.

[0039] During use, in the initial state, the V-shaped spring member 325 elastically compresses the rotating bar 326 so that the bottom edge of the rotating bar 326 fits into the inclined surface of the triangular block 324;

[0040] The process of feeding the metal strip is as follows: one end of the metal strip is pushed from the side close to the U-shaped frame 322 toward the lower support 31, and the metal strip is positioned between the opposing surfaces of the roller 312 and the pressure roller 328. When the metal strip is inserted between the opposing surfaces of the roller 312 and the pressure roller 328, the bottom of the metal strip is supported and restrained by the roller 312. Due to the thickness of the metal strip, the pressure roller 328 is rotated clockwise around the rotation axis 323 to expand the gap between the pressure roller 328 and the roller 312 until the metal strip completely passes between the pressure roller 328 and the roller 312, thus completing the initial positioning of the metal strip.

[0041] The driving motor 2 329 rotates through the belt transmission assembly 3210, causing the pressure roller 328 to rotate clockwise. The driving motor 1 314 drives the support shaft 313 to drive the support roller 312 to rotate, causing the support roller 312 to rotate counterclockwise. Under the action of the friction force between the pressure roller 328 and the support roller 312, the metal strip is transported to one side to achieve loading.

[0042] Example 2

[0043] Reference Figure 1-5 , which is the second embodiment of the present utility model, is different from the first embodiment in that:

[0044] The material limiting component 2 includes two symmetrical translation bars 23 that are slidably installed on the top of the fixed base plate 1. Limiting posts 24 are rotatably installed on both sides of the top of the translation bar 23. When the metal bar moves, the metal bar and the limiting post 24 are in rolling contact, and the friction coefficient is low.

[0045] The material limiting component 2 also includes a bidirectional screw rod 22 that is rotatably installed in the middle of the top of the fixed base plate 1 through a bearing, and a knob is installed at one end of the bidirectional screw rod 22. A threaded hole that is threadedly connected to the bidirectional screw rod 22 is opened in the middle of one side of the translation bar 23. The bidirectional screw rod 22 is driven to rotate by the knob. Under the threaded transmission action of the bidirectional screw rod 22 and the translation bar 23, the two translation bars 23 move toward the middle at the same time, so that the limiting column 24 contacts the side of the metal bar. At the same time, the distance between the limiting columns 24 on both sides is adjustable, so that metal bars of different sizes can be limited to the middle position of the device, so that the metal bar moves in a straight line, which is convenient for the subsequent punching and shearing machine to process the metal bar.

[0046] During use, the bidirectional screw rod 22 is driven to rotate by the knob. Under the threaded transmission action of the bidirectional screw rod 22 and the translation bar 23, the two translation bars 23 move toward the middle at the same time, so that the limiting column 24 contacts the side of the metal bar, further limiting the metal bar.

[0047] The remaining structures are the same as those of Example 1.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
