Description

Technical Field

[0001] The utility model belongs to the technical field of winding equipment, and specifically relates to an elastic band production winding device. Background Art

[0002] In the production process of the elastic band, a winding device is needed to wind the elastic band. The existing winding device is mainly composed of a support frame, an elastic band winding roller and a driving motor. The driving motor drives the elastic band winding roller to rotate to wind the elastic band. There are shortcomings in the limiting method. When removing the wound elastic band, the limiting disk needs to be manually unscrewed, which increases the labor intensity and cannot meet the use requirements.

[0003] The existing patent (CN202221291340.0) proposes a winding device for elastic band production, including a winding base, a first mounting plate is fixedly installed on the top left side of the winding base, a second mounting plate is provided on the top right side of the winding base, an elastic band winding roller is provided between the first mounting plate and the second mounting plate, the right end of the elastic band winding roller is rotatably mounted on the left side of the second mounting plate, the right side of the second mounting plate is fixedly connected to a driving motor, and the left end of the output shaft of the driving motor is fixedly connected to the right end of the elastic band winding roller.

[0004] The elastic band winding roller is driven to rotate by a driving motor, so that the elastic band rotates and is wound around the outer wall of the elastic band winding roller. The first mounting plate and the second mounting plate are provided to ensure the limitation of the winding distance of the elastic band. When the elastic band is wound by the driving motor to drive the winding roller, the elastic band wound by the winding roller may not be smooth and uniform without human interference, resulting in disorderly winding of the elastic band. In addition, because friction may be generated when the elastic band is wound on the winding roller, the elastic band is not wound firmly enough, which may cause it to loosen when it is taken down for storage after winding.

[0005] In view of this, this application is hereby filed. Utility Model Content

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0030] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] When winding the elastic band, if there is no human interference, the elastic band wound by the winding roller may not be smooth and uniform, resulting in the winding of the elastic band becoming disorderly. In addition, because the elastic band may generate friction when winding on the winding roller, the elastic band may not be wound firmly enough, which may cause the elastic band to loosen when it is removed for storage after winding.

[0033] like Figures 1 to 4 As shown, the utility model provides an elastic band production and winding device.

[0034] Specifically, by Figure 2-3 Given, including:

[0035] A bottom plate 1 and a winding assembly arranged on the bottom plate 1;

[0036] The winding assembly includes a winding roller 4 rotatably mounted on the top surface of the bottom plate 1 and a driving motor 3 mounted on the bottom plate 1 for driving the winding roller 4 to rotate;

[0037] The top surface of the bottom plate 1 is symmetrically fixedly connected with a fixing seat 6, a reciprocating screw 7 is rotatably connected between the two fixing seats 6, a guide sleeve 8 is provided on the reciprocating screw 7, a rotating rod 9 is rotatably connected to the inner side of the fixing seat 6, two rotating rods 9 are symmetrically provided, and a clamping rod 10 is fixedly connected between the two rotating rods 9.

[0038] The utility model is used in that one end of the elastic band is passed through the bottom of the outer wall of the guide sleeve 8 and the bottom of the pressure rod 10 and is wound on the winding assembly, and the driving motor 3 is started to drive the winding roller 4 to rotate. At this time, the reciprocating screw 7 rotates to drive the guide sleeve 8 to move toward one end to pull the elastic band evenly wound on the winding roller 4. Moreover, since the reciprocating screw 7 is a screw with a completely closed forward and reverse spiral groove, the guide sleeve 8 will move in the opposite direction after moving to the farthest point on one end on the reciprocating screw 7, and the elastic band will be pulled back and forth and evenly wound on the winding roller 4. The elastic band passes from the pressure rod 10 The bottom passes through, and a spring is installed at one end of the rotating rod 9 close to the fixed seat 6. When the spring is in the initial state, the angle of the rotating rod 9 is in the initial state. When the rotating rod 9 is adjusted, the spring will be acted upon by a force. When the spring is pulled, the elasticity of the spring will gradually convert the stored energy into kinetic energy to drive the rotating rod 9 to rotate in the opposite direction, so that the rotating rod 9 changes to the initial state, which can ensure that the elastic band at the bottom end of the clamping rod 10 is tightened at all times to ensure that the elastic band will not be too loose, resulting in uneven winding and disorderly winding of the elastic band.

[0039] Furthermore, as a specific implementation of the utility model, the utility model provides an elastic band production and winding device.

[0040] Specifically, Figure 4 As shown, the guide sleeve 8 includes a threaded sleeve 801 threadedly connected to the reciprocating screw 7, the outer wall of the threaded sleeve 801 is threadedly connected to an outer cylinder 802, one end of the outer cylinder 802 is rotatably connected to a limit plate 803, the limit plate 803 is slidably installed on the reciprocating screw 7, the bottom end of the limit plate 803 is fixedly connected to a limit block 806, a limit groove 11 is provided on the bottom plate 1, and the limit block 806 is slidably connected in the limit groove 11.

[0041] In the utility model, when winding elastic bands of different sizes, it is necessary to adjust the size of the guide sleeve 8 for adaptation, and adjust the outer cylinder 802 to make it move on the threaded sleeve 801 to achieve the purpose of adjusting the size of the guide sleeve 8. Because it is necessary to guide the movement direction of the guide sleeve 8, a limiting block 806 is fixedly connected to the bottom end of the limiting plate 803, so that the limiting block 806 is slidably connected to the limiting groove 11 opened on the bottom plate 1.

[0042] Furthermore, as another specific implementation of the utility model, the utility model provides an elastic band production and winding device.

[0044] In the utility model, the driving motor 3 is started to drive the winding roller 4 to rotate, and the elastic band is wound on the winding roller 4 to realize the winding work of the elastic band.

[0045] Furthermore, as another specific implementation of the utility model, the utility model provides an elastic band production and winding device.

[0046] Specifically, Figure 3 As shown, a first synchronous wheel 16 is fixedly connected to the outer wall of the driving end of the driving motor 3, a second synchronous wheel 17 is fixedly connected to one end of the reciprocating screw 7, and a synchronous belt 18 is arranged between the first synchronous wheel 16 and the second synchronous wheel 17.

[0047] In the utility model, in order to reduce the use of multiple motors and simplify the device, a second synchronous wheel 17 is fixedly connected to the outer wall of one end of the reciprocating screw 7. When the drive motor 3 rotates, the first synchronous wheel 16 fixedly connected to the outer wall of the driving end of the drive motor 3 drives the second synchronous wheel 17 to rotate through the synchronous belt 18, thereby driving the reciprocating screw 7 to rotate.

[0048] Furthermore, as another specific implementation of the utility model, the utility model provides an elastic band production and winding device.

[0049] Specifically, Figure 3 As shown, a slide groove 12 is provided on the top surface of the base plate 1, and guide grooves 13 are symmetrically provided on both sides of the slide groove 12. A guide block 14 is fixedly connected to the bottom end of the support plate 5, and the guide block 14 is slidably connected in the slide groove 12. Slide blocks are fixedly connected on both sides of the guide block 14, and the slide blocks are slidably connected in the guide groove 13. An electric telescopic rod 15 is provided on the top surface of the base plate 1, and the retracted end of the electric telescopic rod 15 is fixedly connected to one side of the support plate 5 close to the fixed plate 2.

[0050] In the utility model, in order to conveniently remove the elastic band that has been rolled up, the elastic band needs to be removed from the winding roller 4, and the support plate 5 needs to be set as a detachable device. Therefore, a guide block 14 is fixedly connected to the bottom end of the support plate 5, and the guide block 14 is slidably connected in a slide groove 12 opened on the bottom plate 1.

[0051] Furthermore, as another specific implementation of the utility model, the utility model provides an elastic band production and winding device.

[0052] Specifically, Figure 4 As shown, a groove 804 is formed on the limit plate 803 , and one end of the outer cylinder 802 is fixedly connected to a limit seat 805 . The limit seat 805 is an L-shaped plate, and the limit seat 805 is rotatably connected in the groove 804 .

[0053] In the present invention, in order to facilitate the adjustment of the limit plate 803 to move outward without affecting the movement of the limit block 806 , the limit seat 805 fixedly connected to the side of the outer cylinder 802 is rotatably connected to the groove 804 opened on the limit plate 803 .

[0054] Working principle: When in use, one end of the elastic band passes through the bottom of the outer wall of the guide sleeve 8 and the bottom of the pressure rod 10 and is wound on the winding assembly. The drive motor 3 is started to drive the winding roller 4 to rotate. At this time, the reciprocating screw 7 rotates to drive the guide sleeve 8 to move toward one end to pull the elastic band evenly wound on the winding roller 4. Since the reciprocating screw 7 is a screw with a completely closed forward and reverse spiral groove, the guide sleeve 8 will move in the opposite direction after moving to the farthest end on the reciprocating screw 7, pulling the elastic band back and forth and evenly winding it on the winding roller 4. The elastic band passes from the pressure rod 10 The bottom passes through, and a spring is installed at one end of the rotating rod 9 close to the fixed seat 6. When the spring is in the initial state, the angle of the rotating rod 9 is in the initial state. When the rotating rod 9 is adjusted, the spring will be acted upon by a force. When the spring is pulled, the elasticity of the spring will gradually convert the stored energy into kinetic energy to drive the rotating rod 9 to rotate in the opposite direction, so that the rotating rod 9 changes to the initial state, which can ensure that the elastic band at the bottom end of the clamping rod 10 is tightened at all times to ensure that the elastic band will not be too loose, resulting in uneven winding and disorderly winding of the elastic band.

[0055] When winding elastic bands of different sizes, it is necessary to adjust the size of the guide sleeve 8 to adapt, and adjust the outer cylinder 802 to make it move on the threaded sleeve 801 to achieve the purpose of adjusting the size of the guide sleeve 8. Because the movement direction of the guide sleeve 8 needs to be guided, a limiting block 806 is fixedly connected to the bottom end of the limiting plate 803, so that the limiting block 806 is slidably connected to the limiting groove 11 opened on the bottom plate 1.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention.
