[0002] A feeding device is a machine that uses power devices such as conveyor belts, rollers, shafts, and belts to transport materials from one place to another.
[0003] However, during the feeding and conveying process, the tension of the film can change due to the conveying error of different conveying rollers. When the tension is too small, the film will curl up and cannot be processed smoothly. When the tension is too large, the film is easy to tear, causing unnecessary economic losses. Therefore, it is necessary to adjust and maintain the surface tension of the film in real time.
[0004] Therefore, how to provide an automated film feeding tension adjustment device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.
[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The diagram shown is a structural schematic of an automated film feeding tension adjustment device according to an embodiment of the present invention, comprising:
[0034] Feeding table 1;
[0035] Adjustment frame 2 is symmetrically arranged on the front and rear sides of the left end of the feeding table 1, and a fastening roller 3 is movably installed in the middle.
[0036] Placement slot 12 is located in the middle of the feeding table 1, and movable slot 4 is provided on the outer side;
[0037] The transmission structure is located inside the placement slot 12;
[0038] Adjust frame 7, the array of adjustment frame 7 is set at the front and rear ends of the feeding table 1;
[0039] Insert plate 5 is fixedly installed at the bottom of the adjustment frame 7 and inserted into the inside of the movable slot 4;
[0040] Fastening bolts 6 are symmetrically arranged on the front and rear sides of the feeding table 1 and are movably connected to the insert plate 5.
[0041] The reverse lifting structure is located inside the adjusting frame 7 and is meshed with the transmission structure.
[0042] The traction rod 10 is located between the front and rear ends of the reverse lifting structure.
[0043] In this embodiment of the utility model, when in use, the transmission structure is set inside the placement groove 12, and then the position of the adjustment frame 7 is fixed by the cooperation of the insert plate 5 and the fastening bolt 6, so that the reverse lifting structure in the middle of the adjustment frame 7 is engaged with the transmission structure, so that when the transmission structure is running, it can drive the reverse lifting structure to work.
[0044] By arranging a reverse lifting structure at both ends of the feeding table 1, the traction rods 10 at both ends can be adjusted in opposite directions, thereby changing the distance between the traction rods 10 at both ends, and thus adjusting and maintaining the tension of the film inside the traction rods 10 on both sides.
[0045] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in a preferred embodiment of the present invention, the transmission structure includes a shaping plate 13, a circulating transmission toothed belt 14, a cover plate 21, and a drive unit. The shaping plate 13 is symmetrically installed on the front and rear sides of the lower end of the placement groove 12. The circulating transmission toothed belt 14 is disposed within the distance between the placement groove 12 and the shaping plate 13 and is connected to the reverse lifting structure. The cover plate 21 is placed on the upper end of the placement groove 12 to constrain the positions of the shaping plate 13 and the circulating transmission toothed belt 14. The drive unit is disposed on the right end of the cover plate 21 and is connected to the inner side of the circulating transmission toothed belts 14 on the front and rear sides.
[0046] In this embodiment of the utility model, when the drive unit is working, it can drive the circulating transmission toothed belts 14 on the front and rear sides to rotate in the opposite direction, thereby driving the reverse lifting structures on the front and rear sides to lift synchronously, so that the adjacent traction rods 10 can lift and lower synchronously when working.
[0047] By setting up a transmission structure, only one motor 20 is needed to drive the reverse lifting structures at both ends to rotate in the opposite direction, thereby enabling the reverse lifting structures at both ends to rise and fall synchronously and smoothly. This facilitates the adjustment and maintenance of the film tension. Furthermore, by setting up a shaping plate 13, it is convenient to place and install the circulating transmission toothed belt 14. And by setting up a cover plate 21, the working positions of the shaping plate 13 and the circulating transmission toothed belt 14 can be constrained, thereby facilitating the operation of the circulating transmission toothed belt 14.
[0048] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, the reverse lifting structure includes an adjusting screw 8 and a lifting block 9. The adjusting screw 8 is movably installed in the middle of the adjusting frame 7 and passes through the bottom of the adjusting frame 7. A first transmission gear 11 is fixedly connected to it. The outer side of the first transmission gear 11 is meshed with the transmission structure. The lifting block 9 is movably installed on the surface of the adjusting screw 8. The traction rods 10 are arrayed on the inner side of the lifting blocks 9 at both the front and rear ends.
[0049] In this embodiment of the utility model, when the circulating transmission toothed belts 14 on both sides rotate in opposite directions, they drive the first transmission gear 11 to rotate synchronously, thereby enabling all the adjusting screws 8 to rotate synchronously. Since the thread directions on the surfaces of the adjusting screws 8 at the left and right ends are opposite, the lifting blocks 9 on both sides drive the inner traction rods 10 to rise and fall in opposite directions.
[0050] By setting up a reverse lifting structure, the distance between the two traction rods 10 can be adjusted in real time as needed, thereby adjusting the tension of the membrane inside the two traction rods 10.
[0051] like Figure 1 and Figure 3As shown, in a preferred embodiment of the present invention, the drive unit includes a driven gear 16, a transmission rod 17, a positioning frame 19, and a motor 20. The driven gear 16 is arrayed in the middle of the right side of the placement slot 12 and is connected to the inner side of the front and rear end circulating transmission belts 14. The transmission rod 17 is located on the top of the driven gear 16, and a second transmission gear 18 is fixedly installed on the top and meshes with it. The positioning frame 19 is movably installed in the middle of the right side of the cover plate 21 to protect the second transmission gear 18. The motor 20 is movably installed on the top of the positioning frame 19 and penetrates the surface of the positioning frame 19, and is fixedly connected to the top of the front second transmission gear 18.
[0052] In this embodiment of the utility model, when the motor 20 is working, it can drive the second transmission gears 18 on both sides to rotate in the opposite direction, and then drive the driven gears 16 at the lower ends on both sides to rotate in the opposite direction through the transmission rod 17, thereby enabling the circulating transmission belts 14 on both sides to rotate in the opposite direction.
[0053] By setting up a drive unit, only one motor 20 is needed to drive the circulating transmission toothed belts 14 on both the front and rear sides to rotate in the opposite direction, thus facilitating the operation of the reverse lifting structure.
[0054] like Figure 2 , Figure 4 and Figure 5 As shown, in a preferred embodiment of this utility model, the threads on the surfaces of the left and right adjusting screws 8 are arranged in opposite directions, and the rotation directions of the front and rear adjusting screws 8 are arranged in opposite directions.
[0055] In this embodiment of the utility model, when in use, by setting the thread direction of the left and right end adjustment screws 8 to opposite directions, the lifting block 9 on its surface moves up and down, and the rotation direction of the front and rear end adjustment screws 8 is set to opposite directions, so that the lifting block 9 on the surface of the adjustment screw 8 on the same side moves up and down synchronously.
[0056] like Figure 3 , Figure 4 and Figure 5 As shown, in a preferred embodiment of the present invention, slots 15 are arrayed on the right side and front and rear sides of the shaping plate 13, and through holes 22 are arrayed on the right side and front and rear sides of the cover plate 21, and are arranged corresponding to the slots 15.
[0057] In this embodiment of the utility model, when in use, slots 15 are arrayed on both the right side and the front and rear sides of the shaping plate 13, which facilitates the meshing connection between the first transmission gear 11 and the driven gear 16 and the circulating transmission belt 14. Furthermore, through holes 22 are arrayed on both the right side and the front and rear sides of the cover plate 21, which are correspondingly arranged with the slots 15, thereby facilitating the first transmission gear 11 and the driven gear 16 to pass through the through holes 22 and enter the slots 15.
[0058] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment of this utility model, the lifting directions of the left and right end traction rods 10 are opposite, while the lifting directions of the front and rear end traction rods 10 are the same.
[0059] In this embodiment of the invention, when in use, by setting the lifting and lowering directions of the left and right end traction rods 10 in opposite directions, it is convenient to adjust the tension of the film, and by setting the lifting and lowering directions of the front and rear end traction rods 10 in the same direction, it is convenient to drive one end of the film to lift and lower synchronously.
[0060] The above embodiments of this utility model provide an automated film feeding tension adjustment device. When in use, the shaping plate 13 is installed in the lower end of the placement groove 12 in the middle of the feeding table 1, and then the circulating transmission toothed belt 14 is placed in the gap between the shaping plate 13 and the placement groove 12, and then the cover plate 21 is installed in the upper end of the placement groove 12.
[0061] Then, the insert plate 5 at the lower end of the adjustment frame 7 is inserted into the movable slots 4 on both sides of the feeding table 1 and fixed with fastening bolts 6, so that the first transmission gear 11 at the bottom of the adjustment screw 8 inside the adjustment frame 7 passes through the through holes 22 on both sides of the cover plate 21 and then enters the slot 15 on the surface of the shaping plate 13, thereby engaging with the inner side of the circulating transmission toothed belt 14.
[0062] Subsequently, the driven gear 16 passes through the through hole 22 on the right side of the cover plate 21 and enters the slot 15 on the right side of the shaping plate 13, thereby making the driven gear 16 mesh with the inner side of the circulating transmission belt 14, and making the transmission rod 17 at the top of the driven gear 16 enter the through hole 22 on the right side of the cover plate 21, thereby making the second transmission gear 18 at the top of the adjacent transmission rod 17 mesh with each other for transmission connection.
[0063] Then the positioning frame 19 is installed on the top of the cover plate 21, and then the motor 20 is installed on the top of the positioning frame 19, so that the bottom of the motor 20 is movably inserted into the second transmission gear 18 on the front side.
[0064] Thus, when the motor 20 is working, it can drive the second transmission gears 18 on both sides to rotate in the opposite direction, and then drive the driven gears 16 at the lower ends on both sides to rotate in the opposite direction through the transmission rod 17, which in turn causes the circulating transmission belts 14 on both sides to rotate in the opposite direction, thereby driving the first transmission gear 11 to rotate synchronously with the circulating transmission belts 14, and then driving the adjusting screw 8 to rotate synchronously.
[0065] Since the threads on the adjusting screws 8 at the left and right ends are opposite, the lifting blocks 9 on both sides move up and down in opposite directions, thereby adjusting the distance between the traction rods 10 on both sides, and consequently adjusting the tension of the membrane inside the traction rods 10 on both sides.
[0066] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
