Description

Technical Field

[0001] The utility model relates to the technical field of strip material conveying devices, in particular to a strip material conveying mechanism. Background Art

[0002] In the existing strip material conveying device, the strip material is usually extracted from the material trough by a synchronous belt with teeth and grooves distributed on the belt surface, and then lifted to the upper end of the synchronous belt, and then sent to a pair of synchronous belts arranged opposite to each other on the left and right, and the obtained strip material is conveyed in the horizontal direction by the pair of synchronous belts. The synchronous belt that extracts the strip material from the material trough is arranged opposite to the conveying end and the conveying starting end of the pair of synchronous belts arranged opposite to each other on the left and right, so that when the strip material is extracted from the bottom and conveyed upward to the conveying end, it can be connected to the paired synchronous belts, so that the two ends of the strip material are carried on the opposite side edges of the paired synchronous belts.

[0003] The problem with the existing strip material conveying device is that after the strip materials are conveyed to the synchronous belts configured in pairs, their distribution state is relatively messy, and the consistency of the extension direction of the strip materials in the length direction is relatively poor. Utility Model Content

[0004] In order to achieve the purpose of making the distribution state of strip materials more regular and the extension direction in the length direction have better consistency when the strip materials are conveyed along the horizontal plane on the synchronous belt, the utility model provides a strip material conveying mechanism.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a strip material conveying mechanism, including a driving unit arranged on a frame, a pair of synchronous belts 1 matched with the rotating shaft on the driving unit, and a synchronous belt 2 with a plurality of tooth grooves distributed on the belt body. The tooth grooves are formed on the outer belt surface of the synchronous belt 2 and are alternately distributed along the extension direction of the belt body.

[0006] The front ends of the two synchronous belts 1 are matched at the two end sides of the rotating shaft, and the upper ends of the synchronous belts 2 are matched at the middle position of the rotating shaft, so that the synchronous belts 1 and 2 can perform the conveying action synchronously with the rotation of the rotating shaft.

[0007] The rear end of the synchronous belt 1 extends toward the rear side on a horizontal plane, so that the two synchronous belts 1 are arranged in a left-right relative distribution, and the outer belt surfaces of the two synchronous belts 1 can be correspondingly maintained on the same plane.

[0008] The lower end of the synchronous belt 2 extends downward into the material trough, and along with the conveying action of the synchronous belt 2, the synchronous belt 2 can take out the strip material from the material trough and convey it upward by means of the tooth grooves distributed on its belt surface.

[0009] The invention also includes a plurality of L-shaped stoppers respectively fixedly arranged on the belt bodies of the two synchronous belts 1, so that the L-shaped stoppers are alternately arranged on the belt body of the synchronous belt 1 along the extension direction of the belt body, so that the L-shaped stoppers arranged on the two synchronous belts 1 correspond to each other one by one and are relatively located on a straight line along the left-right direction.

[0010] The long arm of the L-shaped stopper is fixed to the belt body of the synchronous belt 1 by a connecting piece such as a screw or a rivet. The short arms of the L-shaped stopper face upward and extend to the outside of the opposite side edges between the two synchronous belts 1.

[0011] Generally, the length of the short arm of the L-shaped stopper should be no less than the thickness of the strip material.

[0012] Optionally, inclined surfaces are formed on the front and rear sides of the short arm on the L-shaped stopper, respectively, so that the upper portion of the short arm is formed into a trapezoidal shape with the short side at the top.

[0013] Optionally, it further comprises an elastic pressing piece and a cross bar matched with the elastic pressing piece. The cross bar is extended on a horizontal plane and fixed on the frame in a spanning manner along the left-right direction.

[0014] A U-shaped bending portion is formed at one end of the elastic pressure piece, and the free end of the U-shaped bending portion is fixed to the middle part of the cross bar, and the end plate at the other end of the elastic pressure piece is relatively located above the belt surface of the second upper end of the synchronous belt, and the end plate extends on the horizontal plane along the front-rear direction.

[0015] An upwardly concave arch is formed at a position where the U-shaped bending portion is connected to the end plate.

[0016] During the conveying action of the second synchronous belt, the upper end surface of the strip material carried by the second synchronous belt to the upper end of its belt body can contact the lower end surface of the end plate of the elastic pressure piece.

[0017] Generally, the free end of the end plate of the elastic pressure piece is extended backward relative to the end of the upper end of the second synchronous belt and outward relative to the end of the second synchronous belt by a certain length.

[0018] Optionally, a pair of pressing plates is further included. The pressing plates are matched with the synchronous belts one by one and are relatively fixed above the upper belt body of the synchronous belt 1. A vertical spacing is formed between the pressing plates and the opposite surfaces of the synchronous belt 1.

[0019] Optionally, the front end of the pressure plate is formed with an arc portion and the arc portion corresponds to the arc portion at the upper front end side of the synchronous belt one. A radial spacing is formed between the arc portion and the relative arc surface of the arc portion at the upper front end side of the synchronous belt one, so that the formed radial spacing value is not less than the thickness of the main body, and preferably the radial spacing is consistent with the thickness of the main body. Such an improvement can better simulate the possibility of significant movement / shaking of the belt body of the synchronous belt one when it moves to the upper front end side position, which helps to smoothly transfer the strip material to the two synchronous belts one.

[0020] Optionally, a side plate is provided above the inner edge of the synchronous belt 1, and the two side plates opposite to each other are both located above the belt surface of the synchronous belt 1 on the same side. The vertical spacing formed between the left and right end surfaces of the two side plates along the left-right direction is consistent with the length of the strip material.

[0021] The protruding arm of the L-shaped stopper extends outwardly relative to the left side surface or the right side surface of the side plate on the same side as the L-shaped stopper.

[0022] A bent arm bent to the left or right is formed at the front end of the side plate, and the vertical spacing along the left-right direction formed between the opposite surfaces of the two bent arms has a changing trend of gradually decreasing from front to back.

[0023] In this way, when the strip material is carried by the synchronous belt 2 and transported upward to between the front end positions of the two synchronous belts 1, the strip material can be moved centrally between the two synchronous belts 1 through the guidance and restraint of the two side plates.

[0024] The beneficial effect of the utility model is that the patent can achieve the purpose of regularly distributing the strip materials and having excellent consistency in the length extension direction when they are transported along the horizontal plane on the synchronous belt, which helps to simplify the process and improve the execution effect of the subsequent process.

[0032] like Figure 1 to Figure 2 A strip material conveying mechanism shown in the figure comprises a driving unit 20 (mainly showing a rotating shaft) arranged on a frame 10, a pair of synchronous belts 1 30 matched with the rotating shaft on the driving unit 20, and a synchronous belt 2 40 with a plurality of tooth grooves 41 distributed on the belt body. The tooth grooves 41 provided on the synchronous belt 2 40 are formed on the outer belt surface of the synchronous belt 2 40 and are alternately distributed along the extension direction of the belt body, that is, the synchronous belt 2 40 is a toothed belt, and a suitable structure and model can be selected from the existing feeding conveyor belts.

[0033] The front ends of the two synchronous belts 1 30 are matched and arranged at the two end sides of the rotating shaft, and the upper ends of the synchronous belt 2 40 are matched and arranged at the middle position of the rotating shaft, so that the synchronous belt 1 30 and the synchronous belt 2 40 can synchronously perform the conveying action with the rotation of the rotating shaft. That is, the two synchronous belts 1 30 and the synchronous belt 2 40 can be driven by the rotating shaft at the same time and synchronously perform the conveying action, and the conveying direction is shown by the arrow in the figure. The rear end of the synchronous belt 1 30 extends toward the rear side on the horizontal plane, so that the two synchronous belts 1 30 are arranged in a left-right relative distribution, and the outer belt surfaces of the two synchronous belts 1 30 can be kept on the same plane accordingly.

[0034] The lower end of the synchronous belt 2 40 extends downward into the material trough 50 , and along with the conveying action of the synchronous belt 2 40 , the synchronous belt 2 40 can take out the strip material 90 from the material trough 50 and convey it upward by means of the tooth grooves 41 distributed on its belt surface.

[0035] In the solution formed by the above structure, the upper end of the synchronous belt 2 40 can be partially corresponding to the front ends of the two synchronous belts 1 30. In this way, when the strip material 90 is conveyed upward between the two synchronous belts 1 30, the two ends of the strip material 90 (in the length direction) can overlap the opposite side edges of the two synchronous belts 1 30, and can be conveyed backward along the horizontal plane to the next process position along with the conveying / transmission action of the synchronous belt 1 30.

[0036] In the innovative and improved structure of the present invention, a plurality of L-shaped blocks 31 are fixedly arranged on the belt bodies of the two synchronous belts 30, so that the L-shaped blocks 31 are evenly arranged alternately on the belt body of the synchronous belt 30 along the extension direction of the belt body (i.e., the front-to-back direction in the figure). The long arm of the L-shaped block 31 (i.e., the main body 311 in the figure) is fixed on the belt body of the synchronous belt 30 by a connecting member such as a screw or a rivet. The L-shaped blocks 31 arranged on the two synchronous belts 30 correspond to each other and are relatively located on a straight line along the left-right direction. With the conveying action of the two synchronous belts 30, each L-shaped block 31 arranged on the two synchronous belts 30 can correspond to each other and remain on a straight line extending along the left-right direction. The short arm of the L-shaped block 31 (i.e., the protruding arm 312 in the figure) faces upward and extends to the outside of the opposite side edges between the two synchronous belts 30.

[0037] Generally, the length of the protruding arm 312 of the L-shaped stopper 31 is preferably greater than the thickness of the strip material 90 (which may be a plate-shaped member, a columnar member, etc.).

[0038] With the help of the L-shaped stops 31 distributed on the synchronous belt 30, when the strip material 90 is conveyed to the position corresponding to the front end portions of the two synchronous belts 30 along with the synchronous belt 2 40, with the help of the protruding arms 312 on a pair of L-shaped stops 31 (opposite to each other on the left and right) moved to the front end portions of the synchronous belt 30, the left and right ends of the strip material 90 are respectively hooked, so that the left and right ends of the strip material 90 are respectively placed between the two adjacent protruding arms 312 on the left synchronous belt 30 and between the two adjacent protruding arms 312 on the right synchronous belt 30, finally achieving the purpose of conveying the strip material 90 to the rear side by the two synchronous belts 30, and during the conveying process, the left and right ends of the strip material 90 can be kept in a state of being arranged in the left-right direction due to the clamping of the protruding arms 312, so that the strip materials 90 carried by the synchronous belt 30 are kept in a state of being arranged in the left-right direction and conveyed to the rear.

[0039] Therefore, in the implementation scheme of the present patent, the innovative and improved structure is used to enable the strip material 90 to be regularly distributed and extend in a consistent direction when being transported along a horizontal plane on a pair of synchronous belts 30, which is helpful for the operation of the next process.

[0040] By making the protruding arm 312 on the L-shaped stopper 31 extend rightward or leftward to the outside of the synchronous belt 30 relative to the left edge or right edge of the synchronous belt 30, it is easy to make the strip material 90 with insufficient length leak into the groove provided below the space between the two synchronous belts 30 when the length of the strip material 90 is less than the left-right spacing between the two synchronous belts 30 (the protruding arms 312 at the opposite side edges) arranged opposite to each other on the left and right sides.

[0041] The protruding arm 312 on the L-shaped stopper 31 has inclined surfaces formed on the upper front side and the upper rear side of the protruding arm 312, respectively, so that the upper part of the protruding arm 312 is formed into a trapezoidal shape with the short side at the top (when viewed from the left or right). This structural design makes it easy to make the left and right ends of the strip material 90 slide smoothly between the protruding arms 312 on two adjacent L-shaped stoppers 31.

[0042] like Figures 1 to 4 As shown, an elastic pressure piece 60 is provided at the upper end of the synchronous belt 2 40 , and a cross bar 61 matching the elastic pressure piece 60 is also provided.

[0043] The cross bar 61 is extended on a horizontal plane and fixed on the frame 10 in a spanning manner in the left-right direction.

[0044] One end of the elastic pressure piece 60 (the end relatively located at the front side) is formed with a U-shaped bend portion and the free end of the U-shaped bend portion is fixed to the middle of the cross bar 61. At the same time, the end plate 62 at the other end of the elastic pressure piece 60 is relatively located above the belt surface at the upper end of the synchronous belt 2 40, and the end plate 62 extends on the horizontal plane along the front-to-back direction.

[0045] An upwardly concave arch is formed at a position where the U-shaped bending portion is connected to the end plate 62 .

[0046] During the conveying action of the synchronous belt 2 40, the upper end surface of the strip material 90 carried by the synchronous belt 2 40 to the upper end of the belt body can contact the lower end surface of the end plate 62 of the elastic pressure piece 60. The arch portion provided between the U-shaped bending portion and the end plate 62 can form a clearance space to ensure that the upper end surface of the strip material 90 can smoothly move below the lower end surface of the end plate 62. The provided U-shaped bending portion can provide elastic power for the elastic pressure piece 60 to float up and down.

[0047] In general, the free end (the rear end shown in the figure) of the end plate 62 of the elastic pressure piece 60 is extended backward relative to the end of the upper end of the synchronous belt 2 40 and outward relative to the end of the synchronous belt 2 40 by a certain length, see Figure 1 .

[0048] like Figure 1 As shown, a pressing plate 70 is respectively provided above the synchronous belt 1 30, so that the pressing plate 70 covers the entire upper belt body of the synchronous belt 1 30 in the front-to-back direction. The pressing plate 70 matches the synchronous belt 1 30 one-to-one and is relatively fixed above the upper belt body of the synchronous belt 1 30. A vertical gap is formed between the pressing plate 70 and the opposite surface of the synchronous belt 1 30.

[0049] like Figure 1 As shown, the pressing plate 70 is fixed to the frame 10 by means of a connecting arm plate 71 fixedly connected to the pressing plate 70, and the pressing plate 70 is relatively suspended above the outer belt surface of the upper belt body of the synchronous belt 30.

[0050] The upper end surface of the main body 311 of the L-shaped stopper 31 fixed on the synchronous belt 30 can be brought into contact with the lower end surface of the pressing plate 70. By setting the pressing plate 70, the floating amplitude of the synchronous belt 30 in the vertical direction during the conveying action can be restricted, ensuring that the strip material 90 clamped between the two opposite protruding arms 312 can be smoothly moved backward and conveyed with the conveying action of the synchronous belt 30, and is not likely to fall off the synchronous belt 30 easily due to the up and down floating of the synchronous belt 30 during the conveying process.

[0051] The front end of the pressing plate 70 is formed with an arc portion 72, and the arc portion 72 corresponds to the arc portion at the upper front end side of the synchronous belt 30. A radial spacing is formed between the arc portion 72 and the arc portion at the upper front end side of the synchronous belt 30, so that the radial spacing value is not less than the thickness of the main body 311, and preferably the radial spacing is consistent with the thickness of the main body 311. Such an improvement can better simulate the possibility of significant movement / shaking of the belt body of the synchronous belt 30 when it moves to the upper front end side, which helps to smoothly transfer the strip material 90 to the two synchronous belts 30.

[0052] A side plate 80 is provided above the inner edge of the synchronous belt 1 30, and the two side plates 80 opposite to each other are both located above the belt surface of the synchronous belt 1 30. The left-right vertical spacing formed between the left end surface and the right end surface of the two side plates 80 is greater than the left-right vertical spacing formed between the opposite ends of the two synchronous belts 1 30, and is consistent with the length of the strip material 90. The protruding arm 312 of the L-shaped stopper 31 extends outward relative to the left side surface or the right side surface of the side plate 80 on the same side. A curved arm bent to the left or right is formed at the front end of the side plate 80, and the left-right vertical spacing between the opposite surfaces of the two curved arms gradually decreases from front to back. In this way, when the strip material 90 is carried by the synchronous belt 2 40 and transported upward to the position between the front ends of the two synchronous belts 1 30, the strip material 90 can be moved centrally between the two synchronous belts 1 30 through the guidance of the two side plates 80.

[0053] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. The present invention can be improved in many aspects without violating the overall concept, and those familiar with the technology can modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the relevant technical field without departing from the spirit and technical concept disclosed by the present invention should still be covered by the claims of the present invention.
