[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of the template herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0040] like Figure 1 and Figure 2 As shown, some embodiments of the utility model provide a wire-paying device, which is mainly used to increase the progress of the ultraviolet light device during operation, thereby facilitating the control of the operating speed of the wire-paying device to improve the wire-paying accuracy.

[0041] The wire-paying device includes a box 100 , a wire-paying roller 200 , a speed reduction mechanism 300 and a driving motor 400 .

[0042] The box body 100 defines a receiving chamber 110 , and the pay-off roller 200 , the speed reduction mechanism 300 and the driving motor 400 are respectively disposed in the receiving chamber 110 .

[0043] The connection between the drive motor 400 and the housing 100 includes any one of bolt connection, clamping, bonding or welding, which can be specifically set according to actual conditions. In this embodiment, the drive motor 400 and the housing 100 are connected by bolts to facilitate installation or disassembly and improve maintenance or replacement efficiency.

[0044] The pay-off roller 200 is disposed in the accommodating chamber 110 and is rotatably connected to the box body 100 .

[0045] Specifically, in this embodiment, the box body 100 has a first side plate 120 and a second side plate 130 that are relatively arranged, the first side plate 120 and the second side plate 130 are parallel to each other, and the axis of the pay-off roller 200 is perpendicular to the plane where the first side plate 120 and the second side plate 130 are located.

[0046] Along the first direction, one end of the pay-off roller 200 is rotatably connected to the first side plate 120 , and the other end of the pay-off roller 200 is rotatably connected to the second side plate 130 .

[0047] It should be noted that the first side plate 120 and the second side plate 130 have a gap with the pay-off roller 200 respectively to avoid friction between the pay-off roller 200 and the first side plate 120 or the second side plate 130 during rotation, so as to ensure the smoothness of the rotation of the pay-off roller 200.

[0048] In this embodiment, the first direction refers to the axial direction of the pay-off roller 200 .

[0049] The deceleration mechanism 300 is arranged on one side of the pay-off roller 200 along the first direction, and the deceleration mechanism 300 is transmission-connected to the pay-off roller 200 so as to limit the rotation speed of the pay-off roller 200 through the deceleration mechanism 300. Through the setting of the deceleration mechanism 300, it is possible to effectively prevent the pay-off roller 200 from rotating at too fast a speed, thereby improving the pay-off accuracy of the cables or UV light strips in the pay-off roller 200, avoiding waste during the pay-off process or the need for manual recovery of the cables, and improving the pay-off efficiency.

[0050] The driving motor 400 is transmission-connected to the pay-off roller 200 via the speed reduction mechanism 300 , and the output end of the driving motor 400 is transmission-connected to the speed reduction mechanism 300 .

[0051] It can be understood that during the operation of the driving motor 400, the speed reduction mechanism 300 is driven to operate through the output shaft of the driving motor 400, and the wire-paying roller 200 is driven to rotate through the speed reduction mechanism 300, so as to provide a speed limiting function during the rotation of the wire-paying roller 200 through the speed reduction mechanism 300, so as to avoid the wire-paying roller 200 from rotating too fast, so as to improve the wire-paying accuracy of the wire-paying roller 200 during the rotation process, and improve the wire-paying accuracy of the wire-paying equipment.

[0052] like Figure 2 As shown, in some embodiments of the present invention, the speed reduction mechanism 300 at least includes a first sprocket 310 , a second sprocket 320 and a first chain 330 .

[0053] The first sprocket 310 is coaxially connected to the pay-off roller 200 , that is, the first sprocket 310 and the pay-off roller 200 rotate synchronously, and the second sprocket 320 is rotationally connected to the first side plate 120 .

[0054] It can be understood that there is a gap between the first sprocket 310 and the second sprocket 320 , and the axis of the first sprocket 310 is parallel to the axis of the second sprocket 320 .

[0055] Specifically, the first sprocket 310 and the second sprocket 320 are connected by the first chain 330 so that when the pay-off roller 200 rotates, the first sprocket 310 is driven to rotate synchronously, and the first sprocket 310 drives the second sprocket 320 to rotate synchronously through the first chain 330.

[0056] It should be noted that since there is friction resistance between the first sprocket 310 and the second sprocket 320 and the first chain 330 during the synchronous rotation, the friction resistance provides resistance to the pay-off roller 200 to prevent the pay-off roller 200 from rotating at too fast a speed during the rotation process, thereby enabling the pay-off equipment to effectively control the pay-off speed of the pay-off roller 200 during operation and improve the pay-off accuracy.

[0057] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, a first tensioning assembly 500 is provided on a side of the first side plate 120 facing the second side plate 130 .

[0058] Among them, the first tensioning assembly 500 includes a first tensioning wheel 510, a first driving member 520 and a first connecting shaft 530, the first driving member 520 is connected to the first side plate 120, the output end of the first driving member 520 is connected to the first tensioning wheel 510 through the first connecting shaft 530, and the first driving member 520 drives the first tensioning wheel 510 to move through the first connecting shaft 530, so that the first tensioning wheel 510 can engage with the first chain 330.

[0059] In this embodiment, the first driving member 520 may be a stepping motor or a screw motor, so as to drive the first tensioning wheel 510 to rotate through the first connecting shaft 530 via the first driving member 520. It is understandable that the first tensioning wheel 510 can mesh with the first chain 330 during the rotation process to adjust the tightness of the first chain 330.

[0060] Exemplarily, if the first chain 330 is loose, the first connecting shaft 530 is controlled to rotate by the first driving member 520, and the first tensioning wheel 510 is driven by the first connecting shaft 530 to abut against the first chain 330, so that the first chain 330 is in a tensioned state, thereby ensuring the deceleration quality of the deceleration mechanism 300 on the pay-off roller 200.

[0061] In addition, if the resistance of the deceleration mechanism 300 to the pay-off roller 200 during rotation is relatively large, that is, the rotation speed of the pay-off roller 200 is too slow, the first driving member 520 can control the first connecting shaft 530 to drive the first tensioning wheel 510 to move away from the first chain 330, so as to reduce the friction between the first tensioning wheel 510 and the first chain 330, thereby reducing the friction between the first sprocket 310, the second sprocket 320 and the first chain 330, thereby adjusting the deceleration of the pay-off roller 200 by the deceleration mechanism 300 to ensure the smoothness of the rotation of the pay-off roller 200.

[0062] like Figures 2 to 4As shown, in some embodiments of the utility model, the reduction mechanism 300 also includes a third sprocket 340, a fourth sprocket 350, a fifth sprocket 360, a sixth sprocket 370, a second chain 380 and a third chain 390, the third sprocket 340 is transmission connected to the fourth sprocket 350 through the second chain 380, and the fifth sprocket 360 and the sixth sprocket 370 are transmission connected through the third chain 390.

[0063] The third sprocket 340 is disposed between the first sprocket 310 and the pay-off roller 200. Specifically, the axes of the first sprocket 310, the third sprocket 340 and the pay-off roller 200 coincide, that is, the first sprocket 310, the third sprocket 340 and the pay-off roller 200 rotate synchronously.

[0064] It is understandable that the pay-off roller 200 drives the third sprocket 340 and the first sprocket 310 to rotate while rotating, and the third sprocket 340 drives the fourth sprocket 350 to rotate through the second chain 380 .

[0065] In addition, the fourth sprocket 350 is coaxially connected to the fifth sprocket 360 so that the fourth sprocket 350 rotates while driving the fifth sprocket 360 to rotate, and the fifth sprocket 360 drives the sixth sprocket 370 to rotate synchronously through the third chain 390 .

[0066] It can be understood that the third sprocket 340 is connected to the fourth sprocket 350 through the second chain 380, and the fifth sprocket 360 and the sixth sprocket 370 are connected through the third chain 390, so as to further increase the speed control quality of the deceleration mechanism 300 for the pay-off roller 200 during rotation, thereby ensuring the stability of the rotation speed of the pay-off roller 200 during rotation, so as to improve the accuracy of the pay-off length of the pay-off roller 200.

[0067] Specifically, in this embodiment, the fifth sprocket 360 and the sixth sprocket 370 are respectively rotatably connected to the first side plate 120. It should be noted that there is a gap between the fifth sprocket 360 and the sixth sprocket 370, and the axis of the fifth sprocket 360 is parallel to the axis of the sixth sprocket 370.

[0068] like Figure 3 and Figure 4 As shown, in some embodiments of the present invention, a second tensioning assembly 600 is provided on a side of the first side plate 120 close to the second chain 380 .

[0069] Among them, the second tensioning assembly 600 includes a second tensioning wheel 610, a second driving member 620 and a second connecting shaft, the second driving member 620 is connected to the first side plate 120, the output end of the second driving member 620 is connected to the second tensioning wheel 610 through the second connecting shaft, and the second driving member 620 drives the second tensioning wheel 610 to move through the first connecting shaft 530, so that the second tensioning wheel 610 can engage with the second chain 380.

[0070] In this embodiment, the second driving member 620 can be a stepping motor or a screw motor, so as to drive the second tensioning wheel 610 to rotate through the second connecting shaft through the second driving member 620. It can be understood that the second tensioning wheel 610 can engage with the second chain 380 during the rotation process to adjust the tightness of the second chain 380.

[0071] In this embodiment, the tension adjustment method of the second chain 380 is the same as the tension adjustment method of the first chain 330 and has the same technical effect, which will not be described in detail here.

[0072] like Figure 3 As shown, in some embodiments of the utility model, a connecting plate 700 is provided between the fourth sprocket 350 and the fifth sprocket 360, and the connecting plate 700 is connected to the first side plate 120 to define a clearance space between the connecting plate 700 and the first side plate 120, that is, the fourth sprocket 350 and the fifth sprocket 360 are located in the clearance space to improve the stability of the relative position of the fourth sprocket 350 and the fifth sprocket 360 in the accommodating cavity 110.

[0073] It should be noted that there is a gap between the fourth sprocket 350, the fifth sprocket 360 and the sixth sprocket 370 and the connecting plate 700 respectively. The fourth sprocket 350, the fifth sprocket 360 and the sixth sprocket 370 are respectively rotatably connected to the connecting plate 700 to avoid friction with the connecting plate 700 and ensure the smoothness of the fourth sprocket 350, the fifth sprocket 360 and the sixth sprocket 370 during rotation.

[0074] like Figure 2 and Figure 4 As shown, in some embodiments of the present invention, a third tensioning wheel 800 is provided on the side of the connecting plate 700 facing the first side plate 120 , and the third tensioning wheel 800 is slidably connected to the connecting plate 700 .

[0075] It should be noted that the third tensioning wheel 800 can engage with the third chain 390 while sliding on the connecting plate 700, so that the tension of the third chain 390 can be adjusted by the third tensioning wheel 800 to adjust the speed limiting quality of the deceleration mechanism 300 on the pay-off roller 200. While ensuring the smoothness of the rotation of the pay-off roller 200, the rotation speed of the pay-off roller 200 can be effectively controlled, thereby improving the accuracy of the pay-off length of the pay-off roller 200 and improving the pay-off quality.

[0076] Specifically, a telescopic rod is provided on the side of the connecting plate 700 facing the second side plate 130, and the connecting plate 700 is provided with a guide channel penetrating the connecting plate 700 along the first direction, and the output end of the telescopic rod passes through the guide channel and is connected to the third tensioning wheel 800, so as to drive the third tensioning wheel 800 to slide along the guide channel through the telescopic rod.

[0077] like Figure 2 and Figure 4 As shown, in some embodiments of the present invention, a seventh sprocket 900 is provided on the side of the connecting plate 700 facing away from the first side plate 120 , and the seventh sprocket 900 is coaxially connected to the sixth sprocket 370 .

[0078] It can be understood that the axis of the seventh sprocket 900 coincides with the axis of the sixth sprocket 370, and there is a gap between the seventh sprocket 900 and the sixth sprocket 370 and the connecting plate 700 respectively, so that the sixth sprocket 370 and the seventh sprocket 900 rotate synchronously while ensuring the smoothness of the rotation of the seventh sprocket 900 and the sixth sprocket 370.

[0079] The seventh sprocket 900 is connected to the eighth sprocket 1000 at the output end of the driving motor 400 through the fourth chain 1100, so that the seventh sprocket 900 is driven to rotate synchronously through the fourth chain 1100 while the eighth sprocket 1000 rotates.

[0080] Specifically, when the drive motor 400 is running, the eighth sprocket 1000 is driven to rotate through the output end of the drive motor 400, and the eighth sprocket 1000 drives the seventh sprocket 900 to rotate synchronously through the fourth chain 1100, and the sixth sprocket 370 is driven to rotate synchronously through the seventh sprocket 900, and the fifth sprocket 360 is driven to rotate synchronously through the third chain 390 by the sixth sprocket 370, and the fourth sprocket 350 is driven to rotate synchronously through the fifth sprocket 360, and the third sprocket 340 is driven to rotate synchronously through the second chain 380 by the fourth sprocket 350, and the first sprocket 310 and the pay-off roller 200 are driven to rotate synchronously through the third sprocket 340, and the second sprocket 320 is driven to rotate synchronously through the first chain 330 by the first sprocket 310.

[0081] like Figure 3 and Figure 4 As shown, in some embodiments of the present invention, a fourth tensioning wheel 1200 , a third driving member 1300 and a third connecting shaft are provided on the side of the connecting plate 700 away from the first side plate 120 .

[0082] Among them, the third driving member 1300 is fixedly connected to the connecting plate 700, and the output end of the third driving member 1300 is connected to the fourth tensioning wheel 1200 through the third connecting shaft, so that the third driving member 1300 drives the fourth tensioning wheel 1200 to move through the third connecting shaft, so that the fourth tensioning wheel 1200 can engage with the fourth chain 1100, thereby adjusting the tension of the fourth chain 1100.

[0083] It should be noted that the fourth tensioning wheel 1200 adjusts the tension of the fourth chain 1100 in the same manner as the first sprocket 310 adjusts the tension of the first chain 330 and has the same technical effect, which will not be described in detail herein.

[0084] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0085] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0086] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
