Description

Technical Field

[0001] The utility model relates to the technical field of mechanical automation equipment, in particular to a fixed-length stepping transmission device for flexible coiled materials. Background Art

[0002] During die-cutting operations, it is sometimes necessary to attach steel sheets or other film materials to the material strip. For example, a robotic arm can be used to absorb the steel sheets and then transfer them to the material strip. Since the thickness of the material strip changes after transfer, and the steel sheets are typically spaced apart, direct feeding of the attached material strip using fixed-length stepping can easily lead to errors, or the factors involved in reducing errors are numerous and complex. Therefore, the applicant has developed a method for more precise feeding by traction of a scrap strip synchronized with the main material strip. Therefore, the development of a supporting device is necessary to address the aforementioned issues. Summary of the Invention

[0003] The purpose of the utility model is to provide a fixed-length stepping transmission device for flexible coiled materials in view of the above-mentioned deficiencies in the prior art.

[0004] The technical solution adopted by the utility model is: a fixed-length stepping transmission device for flexible coiled material, which comprises a material unwinding mechanism, a material belt carrier, and a fixed-length traction mechanism in sequence, wherein: the fixed-length traction mechanism comprises a servo motor, an active roller driven by the servo motor, a pressure belt driven roller arranged parallel to and in contact with the active roller, and a group of vertical plates for installing the servo motor, the active roller, the pressure belt driven roller, and the synchronous transmission pulley; a group of adjustable pressure belt spring pieces are respectively installed at the front and rear ends of the material belt carrier, and the pressure belt spring pieces can be in contact with the material belt carrier to generate a certain pressure on the material belt, so that the material belt is in a flat state on the material belt carrier; the fixed-length traction mechanism is arranged below the running direction of the material belt, and a stripping knife mechanism is also provided above the fixed-length traction mechanism, and a waste belt winding mechanism is also provided behind the fixed-length traction mechanism.

[0005] A pressing mechanism is also provided between the material strip carrier and the stripping knife mechanism. The pressing mechanism includes a pressing base and a pressing cylinder arranged above the pressing base through a suspension. The output end of the pressing cylinder faces downward and is connected to a pressing plate opposite to the pressing base.

[0006] Each group of pressing belt springs consists of two, which are rotatably connected to the spring installation shafts mounted on the front and rear ends of the material belt carrier through spring connecting rings. The spring connecting rings are also provided with adjustment screws that radially interfere with the spring installation shafts.

[0007] A light spot sensor is also provided above the material carrier.

[0008] This flexible coil fixed-length stepping conveyor can simultaneously pull the main material strip by pulling the scrap strip, and does not affect the accuracy of the stepping distance due to factors such as the thickness of the pulled material strip, which helps to simplify the error elimination process. In addition, this utility model can further press the workpiece attached to the material strip, reducing the probability of defective products during subsequent rewinding.

[0010] Figure 2 It is a schematic diagram of the plane structure of the utility model. DETAILED DESCRIPTION

[0011] like Figure 1-Figure 2 As shown, the utility model is a fixed-length stepping transmission device for flexible coiled materials, which includes a material unwinding mechanism (omitted in the figure), a material tape carrier 1, a pressing mechanism 2, and a fixed-length traction mechanism 3;

[0012] Among them: the fixed-length traction mechanism 3 includes a servo motor 31, an active roller 32 driven by the servo motor 31, a pressure belt driven roller 33 arranged parallel to and in contact with the active roller 32, and a group of vertical plates 35 for mounting the servo motor 31, the active roller 32, the pressure belt driven roller 33, and the synchronous transmission pulley 34; the pressure belt driven pulley 33 can be adjusted in height relative to the active roller 32 to control the size of the clamping force between the two; a group of adjustable pressure belt spring pieces 11 are respectively installed at the front and rear ends of the material belt carrier 1, and the pressure belt spring pieces 11 can contact the upper surface of the material belt carrier 1 and generate a certain pressure on the material belt, so that the material belt is in a flat state on the material belt carrier 1; in this embodiment, Each group of pressing tape spring pieces 11 is two, which are rotatably connected to the spring piece mounting shafts 13 mounted on the front and rear ends of the tape carrier 1 through spring piece connecting rings 12. The spring piece connecting rings 12 are also provided with adjusting screws (omitted in the figure) that radially interfere with the spring piece mounting shafts 13, that is, the position of the pressing tape spring piece 11 on the spring piece mounting shafts 13 and the angle relative to the tape carrier 1 can be adjusted, thereby adjusting the position and force of the pressing tape and adapting to the pressing tape requirements of tapes of different widths and thicknesses; the fixed-length traction mechanism 3 is arranged below the running direction of the tape, and a stripping knife mechanism 4 is further provided above the fixed-length traction mechanism 3, and a waste tape winding mechanism 5 is further provided behind the fixed-length traction mechanism 3;

[0013] The circumference of the active roller 32 and the required stepping distance can be used to calculate the pulse equivalent of the servo motor system, that is, to control the rotation angle or number of turns of the servo motor 31, and clamp the material belt and pull the material belt to move with the cooperation of the pressure belt driven wheel 33, and make the material belt move accurately and straightly on the material belt carrier 1 with the cooperation of the pressure belt spring piece 11; this embodiment is suitable for situations where the two sides or bottom of the material belt are waste belts that need to be peeled off. After the main material belt is subjected to laminating processing and other operations on the material belt carrier 1, when it passes through the stripping knife mechanism 4, the main material belt still maintains the running direction of the main material belt and is pulled, and the waste belt is pulled by the fixed-length traction mechanism 3 below and then wound by the waste belt winding mechanism 5; that is, the fixed-length traction mechanism 3 can achieve fixed-length traction by pulling the waste belt, which will not affect the thickness change of the main material belt after processing on the material belt carrier 1 and affect the transmission accuracy, thereby improving the feeding accuracy.

[0014] Furthermore, a pressing mechanism 2 is disposed between the material carrier 1 and the stripping mechanism 4. The pressing mechanism 2 includes a pressing base 21 and a pressing cylinder 22 suspended above the pressing base 21. The output end of the pressing cylinder 22 faces downward and is connected to a pressing plate 23 opposite to the pressing base 21. The pressing mechanism 2 can further tightly bond the workpieces that have been bonded on the material carrier 1.

[0015] A light spot sensor (not shown) is also installed above the material carrier 1 to further confirm whether the transmission distance is sufficient. Of course, the present invention also has several guide rollers, limit rings and other mechanisms for guiding the material supply belt. The figure also omits conventional structures such as the main workbench, so they are not described in detail.

[0016] In summary, the flexible coil fixed-length stepping conveyor of the present invention can achieve synchronous pulling of the main material strip by pulling the scrap strip, and does not affect the accuracy of the stepping distance due to factors such as the thickness variation of the pulled material strip, which helps to simplify the operation of eliminating errors. In addition, the present invention can further press the workpiece attached to the material strip, reducing the probability of defective products during subsequent rewinding.

[0017] The above embodiments are merely exemplary embodiments for illustrating the principles of the present invention, but the present invention is not limited thereto. Those skilled in the art may make various modifications and improvements without departing from the spirit and essence of the present invention, and such modifications and improvements are also considered to be within the scope of protection of the present invention.
