Description

Technical Field

[0001] The utility model belongs to the technical field of communication optical fiber processing, and specifically relates to an automatic cutting device for communication optical fiber. Background Art

[0002] Fiber optic is the abbreviation of optical fiber. Fiber optic communication is a communication method that uses light waves as information carriers and optical fibers as transmission media. In principle, the basic material elements that constitute fiber optic communication are optical fibers, light sources, and light detectors. In addition to being classified by manufacturing process, material composition, and optical properties, optical fibers are often classified by purpose in applications, and can be divided into communication optical fibers and sensor optical fibers.

[0003] During the use of optical fiber, it is often necessary to cut it to a fixed length. In the existing technology, it is generally done manually after manual measurement, which is not only time-consuming and labor-intensive, but also causes the finished optical fiber to be of different lengths, affecting the normal use of communication optical fiber.

[0004] The above problems are in urgent need of improvement and need to be resolved. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, a communication optical fiber automatic cutting device is proposed.

[0006] The technical solution adopted by the utility model is: to provide an automatic cutting device for communication optical fiber, including a driving device, an optical fiber reel installed on the driving device, a transmission device arranged on the right side of the optical fiber reel, a fixed-length cutting device connected to the transmission device, and a clamping device for installing the fixed-length cutting device.

[0007] Preferably, the driving device comprises a motor, a driving platform for mounting the motor, and a positioner arranged on the driving platform; and the optical fiber reel is mounted on the driving platform.

[0008] Preferably, the positioner comprises a positioning body and a wire passing hole provided on the positioning body.

[0009] Preferably, the transmission device includes a transmission bracket, a driving shaft installed on the transmission bracket, a transmission main gear installed on the driving shaft, a driving wheel arranged on one side of the transmission main gear, a driven wheel used in conjunction with the driving wheel, and a driven shaft for installing the driven wheel; the transmission device is connected to the motor shaft belt via the driving shaft.

[0010] Preferably, the fixed-length cutting device includes a cutting bracket, a cutting shaft installed on the cutting bracket, a cutting wheel installed on the cutting shaft, a cutting main gear arranged on the left side of the cutting wheel, a cutting sub-gear meshing with the cutting main gear, a transmission shaft for installing the cutting sub-gear, and a transmission sub-gear installed on the other end of the transmission shaft; a cutting knife is provided on the cutting wheel; and the transmission sub-gear is meshingly connected with the transmission main gear.

[0011] Preferably, the clamping device comprises a clamping platform, a cutting slit provided on the clamping platform, and clamps arranged on both sides of the cutting slit.

[0012] Preferably, the clamp includes a clamping body, a clamping hole opened on the clamping body, clamping wheels arranged on both sides of the clamping hole, main supports arranged on both sides of the clamping wheels, auxiliary supports used in conjunction with the main supports, and a clamping spring for connecting the auxiliary supports and the main supports.

[0013] Preferably, the transmission main gear and the transmission sub gear have the same diameter.

[0014] Preferably, the diameter of the cutting main gear is N times that of the cutting sub-gear, where N is a constant.

[0015] Beneficial effects of the utility model:

[0016] The utility model adopts a driving device and a fixed-length cutting device, which solves the problems of time-consuming and labor-intensive cutting after manual measurement of the size and the different lengths of the optical fibers after cutting. Specifically, a motor is used to drive the transmission device to continuously transport the optical fiber from one position to the clamping device, and the fixed-length cutting device and the transmission device are connected through a transmission shaft. The connection adopts the physical principle of gears. When the diameters of the transmission main gear and the transmission sub-gear are the same, the rotation speeds of the transmission sub-gear and the driving wheel are the same. At the same time, the cutting main gear is N times that of the cutting sub-gear. The transmission sub-gear and the cutting sub-gear are on the same transmission shaft. Therefore, the rotation speed of the driving wheel is N times that of the cutting main gear. The optical fiber cutting fixed length is N times the circumference of the driving wheel. In this way, the lengths of the cut optical fibers are the same and can be cut continuously. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] Specifically, Figures 1 to 7 As shown, an automatic cutting device for communication optical fiber is provided, including a driving device 10, an optical fiber reel 20 installed on the driving device 10, a transmission device 30 arranged on the right side of the optical fiber reel 20, a fixed-length cutting device 40 connected to the transmission device 30, and a clamping device 50 for installing the fixed-length cutting device 40.

[0026] like Figure 1 As shown, the optical fiber is pulled out from the bottom of the optical fiber reel 20, and is transported to the clamping device 50 through the transmission device 30. With the cooperation of the clamping device 50, the fixed-length cutting device 40 performs cutting. When the driving device 10 drives the transmission device 30, the optical fiber can be continuously transported to the clamping device 50 for continuous cutting.

[0027] Furthermore, the driving device 10 includes a motor 11 , a driving platform 12 for mounting the motor 11 , and a positioner 13 disposed on the driving platform 12 ; the optical fiber reel 20 is mounted on the driving platform 12 .

[0028] Furthermore, the positioner 13 includes a positioning body 131 and a wire hole 132 formed on the positioning body 131 .

[0029] The diameter of the wire hole 132 may be equal to the size of the optical fiber.

[0030] like Figure 2 and Figure 3 As shown, after the optical fiber is pulled out from the bottom of the optical fiber reel 20, it first passes through the wire hole 132; in actual operation, the optical fiber will reciprocate back and forth with the optical fiber reel 20. At this time, the positioner 13 can ensure that the optical fiber is always pulled out at one position, and after passing through the wire hole 132, it enters the transmission device 30.

[0031] Furthermore, the transmission device 30 includes a transmission bracket 31, a driving shaft 32 installed on the transmission bracket 31, a transmission main gear 33 installed on the driving shaft 32, a driving wheel 34 arranged on one side of the transmission main gear 33, a driven wheel 35 used in conjunction with the driving wheel 34, and a driven shaft 36 for installing the driven wheel 35; the transmission device 30 is connected to the shaft belt of the motor 11 through the driving shaft 32.

[0032] like Figure 4 As shown, after the optical fiber passes through the wire hole 132, it is inserted between the driving wheel 34 and the driven wheel 35. The size of the gap between the driving wheel 34 and the driven wheel 35 is equal to the size of the optical fiber. Under the action of friction, the driving wheel 34 rotates, which will drive the optical fiber forward to the clamping device 50.

[0033] Furthermore, the fixed-length cutting device 40 includes a cutting bracket 41, a cutting shaft 42 installed on the cutting bracket 41, a cutting wheel 43 installed on the cutting shaft 42, a cutting main gear 44 arranged on the left side of the cutting wheel 43, a cutting sub-gear 45 meshingly connected to the cutting main gear 44, a transmission shaft 46 for installing the cutting sub-gear 45, and a transmission sub-gear 47 installed on the other end of the transmission shaft 46; a cutting knife 48 is provided on the cutting wheel 43; and the transmission sub-gear 47 is meshingly connected to the transmission main gear 33.

[0034] like Figure 5 As shown, after the optical fiber is delivered to the clamping device 50 to a certain length, it is cut by the cutting wheel 43 on the fixed-length cutting device 40, and each cutting cycle is the time for the cutting wheel 43 to rotate one circle, so that the length of the optical fiber cut each time is equal.

[0035] Furthermore, the clamping device 50 includes a clamping platform 51 , a cutting slit 52 provided on the clamping platform 51 , and clamps 53 provided on both sides of the cutting slit 52 .

[0036] Furthermore, the clamp 53 includes a clamping body 531, a clamping hole 532 opened on the clamping body 531, clamping wheels 533 arranged on both sides of the clamping hole 532, main supports 534 arranged on both sides of the clamping wheels 533, a secondary support 535 used in conjunction with the main support 534, and a clamping spring 536 for connecting the secondary support 535 and the main support 534.

[0037] like Figure 6 and Figure 7 As shown, the optical fiber is delivered to the clamping device 50 by being inserted into the clamping hole 532. Under the rebound force of the clamping spring 536 on the clamping wheel 533, the optical fiber is clamped to prevent the optical fiber from moving during cutting. At the same time, the clamping wheel 533 can rotate on the main support 534, reducing the friction of the optical fiber when it is inserted into the clamping hole 532.

[0038] Furthermore, the transmission main gear 33 and the transmission sub gear 47 have the same diameter.

[0039] Furthermore, the diameter of the cutting main gear 44 is N times that of the cutting sub-gear 45, where N is a constant.

[0040] like Figures 1 to 7 As shown, after the optical fiber is transported to a certain length by the clamping device 50, it is cut by the cutting wheel 43 on the fixed-length cutting device 40; when the diameters of the transmission main gear 33 and the transmission sub-gear 47 are the same, and the diameter of the cutting main gear 44 is N times that of the cutting sub-gear 45, the length of the optical fiber is equal to N times the circumference of the driving wheel 34. When in use, the N coefficient can be set according to needs to obtain the corresponding optical fiber length.

[0041] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above and the description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.
