Description

Technical Field

[0001] The utility model relates to the technical field of aluminum strip slitting, in particular to a high-speed aluminum strip feeding mechanism for slitting. Background Art

[0002] When slitting the aluminum strip, first load the large and wide aluminum strip onto the unwinder, and then put one end of the aluminum strip into the traction feeding device in front. The feeding device provides the aluminum strip with forward traction to drive the aluminum coil to rotate and cooperate with the slitting device to complete the purpose of unloading and slitting the aluminum strip.

[0003] The existing feeding equipment mainly includes a frame with two rollers arranged in parallel on the frame, and a lead screw is respectively arranged at both ends of one of the roller shafts, and a rotating wheel is arranged at one end of the lead screw. When the aluminum strip is placed between the two rollers, it is first necessary to manually operate the rotating wheels at both ends to use the lead screw to drive the roller connected to it to lift upward, thereby increasing the distance between the two rollers to facilitate the placement of the aluminum strip between the two, and then press the roller onto the aluminum strip through the rotating wheel, and then use the motor to drive the roller to rotate, and the roller uses friction to transport the aluminum strip forward.

[0004] The above-mentioned feeding method mainly has the following problems: 1. When the aluminum strip is placed between the two rollers, the lifting and lowering of the rollers is mainly achieved by manually driving the rotating wheels. When operating manually, the rotating wheels need to be operated one by one, which is not only inefficient, but also has high labor intensity due to the heavy weight of the rollers and the high physical strength consumed by the manpower;

[0005] 2. After the aluminum strip is placed between the two rollers, when one of the rollers is lowered, due to manual operation, the pressure exerted by the roller on the aluminum strip will be different, and the aluminum strip will be deformed at the end with greater pressure. Therefore, the consistency of the pressure of the roller on the aluminum plate cannot be guaranteed.

[0006] Therefore, there is an urgent need for a high-speed aluminum strip feeding mechanism for slitting, which is used to reduce the labor intensity when adjusting the rollers, improve the adjustment efficiency and ensure the consistency of the pressure applied to the aluminum strip. Utility Model Content

[0007] In view of the above technical problems, the utility model provides a high-speed aluminum strip feeding mechanism for slitting, which is used to solve the problem that the lifting and lowering adjustment of the existing rollers are all done manually, resulting in low adjustment efficiency and high labor intensity, and the problem that the consistency of the pressure of the rollers on the aluminum strip cannot be guaranteed.

[0008] The above technical objectives of the utility model are achieved through the following technical solutions:

[0013] A second driving wheel is provided on the top of one of the driving screws close to the carrier plate, an auxiliary screw is passed through the carrier plate, a third driving wheel is provided on the end of the auxiliary screw close to the second driving wheel, a second driving belt is provided between the second driving wheel and the third driving wheel, a rotating seat is provided on the end of the vertical plate away from the third driving wheel, and the other end of the auxiliary screw is rotatably connected to the rotating seat.

[0014] Furthermore, the driving frame also includes a supporting arm, a positioning hole is formed through the supporting arm, the positioning hole extends to the inside of the vertical plate, and a positioning column is provided in the positioning hole.

[0015] Furthermore, a slider is provided at one end of the carrier plate close to the vertical plate, and a slide rail is provided at a position of the vertical plate corresponding to the slider along the moving path of the carrier plate, and the slide rail cooperates with the slider.

[0016] Furthermore, a U-shaped mounting opening is provided at the position of the vertical plate located at the rotating seat, and limiting grooves are provided on both sides of the rotating seat, and the rotating seat is installed in the U-shaped mounting opening through the limiting grooves.

[0017] Furthermore, a universal joint is provided between the reducer and the roller shaft of the first pressing roller.

[0018] Furthermore, the radii of the first driving wheel, the second driving wheel and the third driving wheel are equal.

[0019] In summary, the beneficial technical effects of the utility model are:

[0020] (1) The lifting motor is used to drive the first gear to mesh with the second gear to rotate the driving screw. The driving screw further realizes the synchronous rotation of the two driving screws through the first driving wheel and the first driving belt. The first driving screw further acts on the first pressure roller to realize the lifting and lowering relative to the second pressure roller, thereby replacing manual operation with mechanical transmission, reducing the labor intensity when adjusting the first pressure roller, and at the same time improving the efficiency of adjustment and ensuring the consistency of pressure applied to the aluminum strip, thereby avoiding deformation caused by uneven pressure; at the same time, the lifting motor is used to realize the lifting and lowering of the carrier plate along the slide rail through the third driving wheel and the auxiliary screw, thereby ensuring that the lifting motor can be lifted and lowered synchronously with the driving screw.

[0021] (2) The positioning column and the positioning hole are used to realize the detachable installation of the driving frame and the vertical plate, which facilitates the installation of the driving screw on the vertical plate and the installation of the first pressure roller and the second pressure roller in the U-shaped installation opening.

[0023] (4) The limiting groove can be used to limit the first pressing roller between the two vertical plates. At the same time, when the first pressing roller is raised or lowered, the cooperation between the limiting groove and the vertical plates can be used to improve the movement guidance.

[0024] (5) The universal joint can transmit the power from the reducer, while preventing the reducer from moving with the first pressure roller when it is raised or lowered.

[0025] (6) By setting the radii of the first driving wheel, the second driving wheel and the third driving wheel to be the same, the consistency of the actions of the driving screw and the auxiliary screw is ensured, thereby ensuring the synchronization of the lifting and lowering of the first pressure roller and the lifting motor.

[0034] See attached Figure 1, shown is a high-speed aluminum strip feeding mechanism for slitting, including a frame 1, a reducer 3, and a driving motor 2, wherein the frame 1 includes two parallel vertical plates 4, and a U-shaped mounting opening 9 is vertically opened on the two vertical plates 4.

Limiting grooves 26 are opened on both sides of the rotating seat 10, and the rotating seat 10 is clamped in the U-shaped mounting opening 9 through the limiting grooves 26. When in use, the rotating seat 10 slides up and down along the U-shaped mounting opening 9 through the limiting grooves 26, and at the same time, the first pressing roller 11 and the second pressing roller 12 are arranged in parallel. One end of the roller shaft of 12 is connected to the reducer 3 through a universal joint 27, and the reducer 3 is connected to the driving motor 2 through a pulley. When in use, the reducer 3 is driven to rotate by the driving motor 2, and the reducer 3 further realizes the rotation of the first pressure roller 11 and the second pressure roller 12 along the rotating seat 10 through the universal joint 27. It should be noted that the universal joint 27 here is specifically a universal coupling, which not only realizes the transmission of power, but also realizes the change of the angle between the reducer 3 and the first pressure roller 11, further avoiding the reducer 3 from rising and falling with the first pressure roller 11 when the first pressure roller 11 moves up and down; it should also be noted that the first pressure roller and the second pressure roller rotate in opposite directions;

[0035] See attached Figure 2 , Attachment Figure 3 , Attachment Figure 4 , the vertical plate 4 shown is provided with a driving frame 5 at the top of the U-shaped mounting opening 9, the driving frame 5 includes a driving nut 6 located just above the rotating seat 10 and support arms 7 arranged on both sides of the driving nut 6, a positioning hole is formed through the support arm 7, the positioning hole extends into the vertical plate 4, a positioning column 8 is arranged in the positioning hole, the driving frame 5 and the vertical plate 4 are detachably connected through the positioning column 8, and the first pressing roller 11 and the second pressing roller 12 are conveniently installed between the two vertical plates 4 in sequence through the detachable installation of the driving frame 5 when in use;

[0036] At the same time, the two driving frames 5 are equipped with a driving screw 13 through a driving nut 6, and one end of the driving screw 13 is rotatably connected to the rotating seat 10. A carrier plate 14 is slidably provided on one side of one of the vertical plates 4, and a slider 25 is provided on the end of the carrier plate 14 close to the vertical plate 4. At the same time, a slide rail 24 is vertically provided at the position of the vertical plate 4 corresponding to the slider 25. The slide rail 24 and the slider 25 cooperate. A lifting motor 15 is installed on the carrier plate 14 through a mounting plate. A first gear 16 is provided at the output end of the lifting motor 15, and a second gear 17 is meshed on the first gear 16. The second gear 17 is sleeved on the nearest driving screw 13 and is fixedly connected. When the lifting motor 15 drives the first gear 16 to rotate, the first gear 16 will further drive the screw 13 to rotate through the action of the second gear 17;

[0037] At the same time, a first driving wheel 18 is provided at the end of each of the two driving screws 13, and a first driving belt 20 is provided between the two first driving wheels 18. When in use, the first gear 16 and the second gear 17 are driven to rotate by the lifting motor 15, and the second gear 17 will further act on the driving screw 13 connected thereto to rotate, and the driving screw 13 will further realize the simultaneous rotation of the two driving screws 13 through the first driving belt 20, and the driving screw 13 further drives the first pressing roller 11 to move up and down along the U-shaped mounting opening 9. Therefore, in the entire lifting and lowering adjustment process of the first pressing roller 11, the lifting motor 15 is used as the power source to replace the manual operation, thereby reducing the labor intensity when rotating the driving screw 13. At the same time, the first driving belt 20 is used to realize the synchronous action of the two driving screws 13, which is more convenient and efficient than the original manual adjustment one by one. At the same time, the two driving screws 13 are synchronized by mechanical driving, so that the pressure of the first pressing roller 11 and the second pressing roller 12 on the aluminum strip is consistent and uniform, thereby avoiding the deformation of the aluminum strip caused by uneven pressure.

[0038] At the same time, an auxiliary lead screw 21 is provided through the center of the carrier plate 14, and the other end of the auxiliary lead screw 21 is rotatably connected to a connecting seat 23, and the connecting seat 23 is fixedly connected to the vertical plate 4. A second driving wheel 19 is provided on the top of the driving lead screw 13 close to the carrier plate 14, and a third driving wheel 22 is provided at the other end of the auxiliary lead screw 21. A second driving belt 28 is provided between the second driving wheel 19 and the third driving wheel 22. When the lifting motor 15 drives the driving lead screw 13 to rotate, the auxiliary lead screw 21 is linked to move synchronously by the second driving belt 28, and then the carrier plate 14 is driven to move synchronously with the driving lead screw 13, thereby ensuring that the lifting motor 15 can move together with the lifting of the driving lead screw 13;

[0039] When in use, the lifting motor 15 is started, and the lifting motor 15 drives one of the driving screws 13 to rotate through the meshing first gear 16 and the second gear 17. The driving screw 13 further drives the other end of the driving screw 13 through the first driving wheel 18 and the first driving belt 20. The first pressing roller 11 slides upward along the U-shaped mounting opening 9 under the simultaneous action of the two driving screws 13. At this time, the distance between the first pressing roller 11 and the second pressing roller 12 increases, so that the aluminum strip can be easily passed between the two. When the driving screw 13 is in motion The second driving wheel 19, the third driving wheel 22 and the second driving belt 28 are used to assist the screw 21 to rotate. The auxiliary screw 21 further acts to cause the carrier plate 14 equipped with the lifting motor 15 to rise and fall synchronously along the slide rail 24. Then the lifting motor 15 is reversed and the driving screw 13 is used to simultaneously move the first pressure roller 11 downward and abut against the surface of the aluminum strip. Then the driving motor 2 is started and the first pressure roller 11 and the second pressure roller 12 are driven to rotate through the reducer 3. The aluminum strip moves forward under the friction of the first pressure roller 11 and the second pressure roller 12 to complete the feeding.
