Description

Technical Field

[0001] The present invention relates to the technical field of clip-type feeders, specifically a double-tape clip-type feeder. Background Art

[0002] There are mainly two types of clamping-type feeding: clip-edge type and clip-roller type. The clip-roller type mainly uses one or two pairs of reciprocating rollers to clamp the blank to achieve the feeding device, which has the same function as the roller-type feeding. The clip-edge type has two types: surface clip-edge and side clip-edge.

[0003] In a material bracket of a high-speed clip-type feeder disclosed in the existing patent publication number CN106040893B, through the cooperation of an adjustment block, an adjustment screw, and a guide rail, the position of the bracket can be conveniently adjusted by using a first handle and a second handle; by loosening the bolt, the positions of the clip block and the rolling bearing on the bracket can be adjusted. The first handle and the second handle are vertically arranged to facilitate turning the adjustment screw; the material bracket of the high-speed clip-type feeder also has a horizontal rolling bearing, which can effectively prevent the material from shaking caused by the vibration of the punching machine and ensure that the feeding center remains stable.

[0031] The top fixing mechanism 14 includes a mounting frame and two sets of clamping plates 37, a contact roller 38 is installed at the bottom of the clamping plate 37, and an adjusting member for adjusting the height of the clamping plate 37 is connected to the mounting frame;

[0032] The distance between the clamping plate 37 and the material belt can be adjusted by the adjusting member according to the thickness of the material belt, so that the feeder can be suitable for conveying material belts of different thicknesses and is convenient to use. When the clamping plate 37 is adjusted, the contact roller 38 can contact the material belt.

[0033] The clamping and conveying mechanism 18 includes a feeding plate 19 , and a reciprocating member for driving the feeding plate 19 to reciprocate is installed in the chassis 16 .

[0034] The reciprocating member includes four groups of rotating disks 22, on which a swinging member is installed, and an eccentric column 23 is connected to the eccentric part of the rotating disk 22, and the shaft end of the eccentric column 23 away from the rotating disk 22 is connected to the driving member, and the sides of the two groups of rotating disks 22 that are close to each other are connected by a stabilizing rod 39, and the axis of the stabilizing rod 39 coincides with the axis of the eccentric column 23;

[0035] The swing member includes a swing ring 21, the inner wall of the swing ring 21 is rotatably matched with the outer wall of the rotating disk 22, the top of the swing ring 21 is connected to the extension rod 40, the bottom of the feeding plate 19 is connected to a mounting seat 20 rotatably connected to one end of the extension rod 40 away from the swing ring 21, the side of the swing ring 21 away from the extension rod 40 is connected to a positioning frame 41, a strip groove is provided on the positioning frame 41, and a positioning column is installed on the inner wall of the chassis 16, and the positioning column passes through the strip groove;

[0036] The driving member includes a synchronous belt 25 and a motor. Two groups of driving disks 24 on the same side are connected by the synchronous belt 25. One end of the driving disk 24 is connected to the end of the eccentric column 23. The ends of the driving disk 24 away from the eccentric column 23 are connected to the rotating shaft 26. One group of rotating shafts 26 is connected to the motor shaft at the power output end of the motor. The motor is installed on the chassis 16. The inner wall of the chassis 16 is connected to a rotating seat. The other three groups of rotating shafts 26 are rotatably matched with the rotating seat.

[0037] When the motor works, it can drive the driving disc 24 to rotate, thereby driving another group of driving discs 24 to rotate through the synchronous belt 25. When the driving disc 24 rotates, it will drive the eccentric column 23 to rotate. The eccentric column 23 will drive the rotating disc 22 to swing around the axis of the eccentric column 23. The rotating disc 22 moves within the swing ring 21. The swing ring 21 is restricted by the positioning frame 41. When the swing ring 21 swings, the positioning post slides within the strip-shaped groove, and the end of the extension rod 40 performs a closed-loop reciprocating curve motion. This reciprocating curve motion is biased towards an ellipse and can drive the feeding plate 19 to perform a reciprocating curve motion similar to an ellipse. During the motion, when the contact plate 27 on the feeding plate 19 contacts the material tape, it can give the material tape a linear motion force to push the material tape forward. Thus, during the reciprocating motion of the swing ring 21, the contact plate 27 performs intermittent linear conveying on the material tape.

[0038] Two groups of contact plates 27 are connected to the feeding plate 19. A storage groove for storing the contact plates 27 is provided on one side of the feeding plate 19 close to the top fixing mechanism 14.

[0039] By rotating the adjusting screw 29, the distance between the contact plate 27 and the feeding plate 19 can be adjusted. When the contact plate 27 is adjusted, the guiding rod 28 slides within the hole on the feeding plate 19, enabling the contact plate 27 to be stably adjusted, which is convenient for adjusting the distance between the contact plate 27 and the feeding plate 19 according to the thickness of the material tape.

[0040] The mounting bracket includes a top plate 30. Vertical plates 31 are connected to both sides of the top plate 30. The bottom of the vertical plate 31 is connected to a fixing plate 32.

The power output end of the cylinder is connected to a piston rod 36. A strip-shaped groove 35 is provided on the top plate 30. The piston rod 36 passes through the strip-shaped groove 35 and is connected to a clamping plate 37. Positioning plates 34 are connected to both sides of the bottom of the protective box 33, and bolt holes are provided on the positioning plates 34; A positioning seat for the stable rotation of the contact roller 38 is connected to the bottom of the clamping plate 37. A rubber sleeve is connected to the outer wall of the rotating shaft 26;

[0042] The distance between the protective boxes 33 can be adjusted. During the adjustment, the piston rod 36 can move within the strip-shaped groove 35;

[0043] When the cylinder works, it can adjust the telescopic movement of the piston rod 36, so as to control the distance between the clamping plate 37 and the strip, and further control the stable contact between the contact roller 38 and the strip. The contact roller 38 can rotate in the positioning seat. When the clamping and conveying mechanism 18 conveys the strip, the strip can roll at the bottom of the contact roller 38, reducing the wear on the strip.

[0044] A shock-absorbing seat 17 is provided at the bottom of the chassis 16. A sliding groove is provided at the top of the shock-absorbing seat 17. The outer wall of the chassis 16 is slidably matched with the inner wall of the sliding groove. A plurality of groups of springs installed in the sliding groove are connected to the bottom of the chassis 16. The shock-absorbing seat 17 can buffer the vibration of the chassis 16, reducing the vibration transmitted by the chassis 16 to the whole feeder, which is beneficial for use.

[0045] An input roller group 13 for material input is provided on one side of the workbench 11. An output roller group 15 for material output is provided on the side of the workbench 11 away from the input roller group 13. Both the input roller group 13 and the output roller group 15 include an upper conveying roller and a lower conveying roller arranged at the bottom of the upper conveying roller.

The strip can pass through between the upper conveying roller and the lower conveying roller, be input from the input roller group 13 to the clamping and conveying mechanism 18, and then be output from the output roller group 15.

[0046] The working principle of the present invention is: The strip is input from the input roller group 13 to the clamping and conveying mechanism 18. According to the thickness of the strip, the distance between the two sets of clamping plates 37 and the strip is adjusted respectively by the cylinder, controlling the stable contact between the contact roller 38 and the strip. The clamping and conveying mechanism 18 works, and the contact plate 27 conveys the strip in an intermittent straight line. When conveying the strip, the strip can roll at the bottom of the contact roller 38, reducing the wear on the strip.
