Description

Technical Field

[0001] The utility model relates to a friction coiling device, in particular to an adjustable friction coiling device applicable to paper tubes with different pipe diameters. Background Technique

[0002] Central coiling is carried out by rotating the central axis of the coil. The diameter or width of the finished coil is related to the size and stiffness of the coiling central axis. The greater the stiffness, the larger the diameter of the central axis, the larger the diameter of the finished coil, and the wider the width of the finished coil. This method has the following disadvantages: 1. The greater the stiffness, the larger the diameter of the central axis, and the heavier the mass of the central axis, resulting in higher costs. Taking a 3.5-inch 1.8m air shaft as an example, its weight is generally more than 30kg, so it is limited in actual use; 2. This coiling method often requires more air shafts, and the operating cost is much higher than that of the friction coiling method.

[0003] Chinese patent document CN202625437U discloses an adjustable friction coiling device applicable to paper tubes with different pipe diameters, including a driving roller, a driven roller, a paper tube placed on the driving roller and the driven roller, and a driving mechanism for driving the driving roller and the driven roller to rotate in the same direction. It also includes a spacing adjustment mechanism for adjusting the spacing between the driving roller and the driven roller. When using the adjustable friction coiling device applicable to paper tubes with different pipe diameters in the above patent document, if the diameter of the paper tube is small, the spacing between the driving roller and the driven roller is reduced through the spacing adjustment mechanism to prevent the paper tube from falling off easily; if the diameter of the paper tube is large, the spacing between the driving roller and the driven roller is increased accordingly; when the coil is coiled to a large diameter, the spacing between the driving roller and the driven roller is increased through the spacing adjustment mechanism, so that the coil is not easy to roll down and the coiling process is more stable; the above patent document can meet the coiling requirements of large-diameter coils without using large-diameter paper tubes or large-diameter rollers.

[0004] In the implementation process of the above patent document, the spacing between the driving roller and the driven roller can be increased through the spacing adjustment mechanism, but the adjustment and support of its tensioning mechanism are not stable enough, resulting in easy shaking of the tensioning mechanism during use and easy loosening of the device during use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to make the technical means, creative features, achieved purposes and effects of the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific embodiments.

[0022] Such asFigure 1 As shown in the figure, an adjustable friction winding device applicable to paper tubes of different pipe diameters includes a lower backing plate 1. At the four corners of the lower end of the outer surface of the lower backing plate 1, support legs 2 are fixedly connected. A chute 3 communicating with the outside is provided at the left part of the upper end of the outer surface of the lower backing plate 1. A driving component 4 is fixedly connected to the right part of the upper end of the outer surface of the lower backing plate 1, which can cooperate with a motor 5 to perform the function of friction winding the coil 9 in the same direction. A motor 5 is fixedly connected to the front part of the driving component 4. A driven component 6 is slidably connected to the left part of the upper end of the outer surface of the lower backing plate 1, which can drive the coil 9 to rotate under the rotation of the driving component 4. A tensioning mechanism I 7 is slidably connected to the middle part of the lower backing plate 1, which can adjust the tension degree of the belt 8. The driving component 4, the driven component 6, and the front and rear sides of the upper part of the driven component 6 are symmetrically sleeved with a belt 8 together. A coil 9 is placed on the side where the driving component 4 and the driven component 6 are close to each other. A paper tube I 91 is sleeved in the middle of the inner cavity of the coil 9. A pushing mechanism 10 is fixedly connected to the left part of the upper end of the outer surface of the lower backing plate 1, which can adjust the distance between the driving component 4 and the driven component 6. An adjusting mechanism 11 is fixedly connected to the middle part of the lower end of the outer surface of the lower backing plate 1, which can drive the tensioning mechanism I 7 to perform lifting adjustment.

[0023] To achieve the purpose of friction winding the coil 9 in the same direction in cooperation with the motor 5, refer to Figure 2 As shown in the figure, the driving component 4 includes two fixing columns I 41. A driving roller 42 is rotatably connected to the upper parts of the two fixing columns I 41. Limiting discs I 43 are symmetrically fixedly connected to the front end and the rear end of the outer surface of the driving roller 42, which can drive the belt 8 to rotate through the rotation of the driving roller 42. The middle part of the front end of the outer surface of the limiting disc I 43 located at the front is fixedly connected to the output end of the rear part of the motor 5.

[0024] To achieve the purpose of driving the coil 9 to rotate under the rotation of the driving component 4, refer to Figure 2 As shown in the figure, the driven component 6 includes a carrier 61. A connecting block 62 is fixedly connected to the middle part of the left end of the outer surface of the carrier 61. A driven roller 63 is rotatably connected to the upper part of the carrier 61. Limiting discs II 64 are symmetrically fixedly connected to the front end and the rear end of the outer surface of the driven roller 63. The lower end of the outer surface of the carrier 61 is slidably connected to the inner cavity of the chute 3.

[0025] When the motor 5 starts to drive, the driving roller 42 and the limiting disc I 43 will rotate. At this time, through the connection between the belt 8 and the limiting disc II 64, the driven roller 63 is driven to rotate in the same direction as the driving roller 42, and then the coil 9 placed on the upper surface of the driving roller 42 and the upper surface of the driven roller 63 is friction wound.

[0026] To achieve the purpose of adjusting the distance between the driving component 4 and the driven component 6, refer to Figure 3 ​, the driving mechanism 10 includes a fixed seat 101. A threaded rod 102 is threadedly connected to the middle of the fixed seat 101, and the right end of the outer surface of the threaded rod 102 is rotatably connected to the middle of the front end of the outer surface of the connecting block 62.

[0028] To achieve the purpose of adjusting the tension of the belt 8, refer to Figure 4 , the first tensioning mechanism 7 includes a cross plate 71. Fixed columns two 72 are symmetrically and fixedly connected to the front and rear parts of the upper end of the outer surface of the cross plate 71. A tensioning roller 73 is rotatably connected to the side where the upper parts of the two fixed columns two 72 are close to each other. Limit plates three 74 are symmetrically and fixedly connected to the front end and the rear end of the outer surface of the tensioning roller 73, which can achieve the function of adjusting the tightness of the coiled material 9.

[0029] To achieve the purpose of driving the first tensioning mechanism 7 to perform lifting adjustment, refer to Figure 4 , the adjusting mechanism 11 includes a protective sleeve 111. A hydraulic cylinder 112 is installed and fixed in the inner cavity of the protective sleeve 111. L-shaped plates 113 are symmetrically and fixedly connected to the left end and the right end of the outer surface of the protective sleeve 111, which can realize the function of connecting with the protective sleeve 111 to support and protect the hydraulic cylinder 112. The upper ends of the outer surfaces of the two L-shaped plates 113 are fixedly connected to the lower end of the outer surface of the lower backing plate 1. The output end of the piston rod of the upper part of the hydraulic cylinder 112 is fixedly connected to the middle of the cross plate 71.

[0030] It should be noted that the specific installation methods of the motor 5 and the hydraulic cylinder 112, the connection methods of the oil circuit and the circuit, and the control method in the present invention are all conventional designs, and the present invention will not be elaborated in detail.

[0031] Working principle of the utility model: During friction winding, the lower backing plate 1 is wound around the outside of the paper tube 91 and placed on the upper parts of the driving roller 42 and the driven roller 63. At this time, the driving motor 5 is driven, so that the first limiting disc 43 and the second limiting disc 64 can be driven to rotate in the same direction through the belt 8, and then the driving roller 42 and the driven roller 63 are driven to rotate synchronously therewith. During this period, the connection between the third limiting disc 74 and the belt 8 can restrict the tightness of the belt 8 to prevent the phenomenon that the belt 8 is not tight enough and the driving roller 42 and the driven roller 63 cannot rotate fully. When it is necessary to adjust the diameter of the wound coil 9 during friction winding, the bearing frame 61 is adjusted by rotating the threaded rod 102 to make it move, so as to achieve the purpose of adjusting the distance between the driven roller 63 and the driving roller 42. At the same time, the lifting distance of the cross plate 71 can be adjusted by driving the hydraulic cylinder 112, so that the two third limiting discs 74 can continue to adjust the tension degree of the belt 8.
