Description

Technical Field

[0001] The invention relates to the technical field of winding equipment, and in particular to a winding device for a braiding machine. Background Art

[0002] LED light strip refers to LEDs assembled on a strip-shaped flexible circuit board or hard board. It is named because its product shape is like a strip. It has gradually emerged in various decoration industries because of its long service life, energy saving and green environmental protection. Light strip is the abbreviation of LED light strip. Most people are not used to the long noun, so they omit the LED in front and call it light strip directly. This name of light strip also includes many old-fashioned light strips such as large two-wire, large three-wire, round two-wire, etc. that directly use wires to connect LEDs without FPC or PCB. Of course, it also includes flexible light strips and hard light strips. When packaging the LED light strips, the LED light strips need to be rolled up.

[0003] Specifically, patent number CN218931151U is a winding device for LED light strip braiding machine, and patent number CN217708156U is a LED light braiding machine. There is a problem when the above devices are winding the light strip, that is, when the reel for winding the light strip is full of light strip, the light strip is cut by manual or mechanical shearing, and then the clamp fixing the reel is disassembled to remove the reel for subsequent packaging and other work. At this time, it takes a long time to disassemble and replace the reel, which causes the braiding machine to stop. The work can be continued only after the new reel is installed. Otherwise, there is no fixing device at the end of the light strip to straighten it and wind it, resulting in the light strip produced in the gap of the above-mentioned replacement equipment being in a bent state and scattered all over the ground. After replacing the new reel, the scattered light strip needs to be quickly rearranged and wound and fixed with the reel before the subsequent winding work can be continued, which increases the labor intensity and operation difficulty. Although the stopping of the tape machine in the gap of the above-mentioned replacement of equipment will not increase the labor intensity and operation difficulty, it will seriously affect the processing efficiency.

DETAILED DESCRIPTION

[0021] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0022] Embodiment 1:

[0023] A winding device for a braiding machine comprises a base 1, a vertical plate 2 for mounting a motor 13 is arranged on the top of the base 1, a circular plate 4 located in front of the vertical plate 2 is arranged on the output shaft of the motor 13, a winding mechanism 5 is arranged at the left and right ends of the front side of the circular plate 4, and support rods 6 are arranged on the upper and lower sides of the circular plate 4 between the two sets of winding mechanisms 5. Figure 1 , 3 As shown, the upper support rod 6 is arranged near the upstream winding mechanism 5 ( Figure 1 , 3 On the circular plate of the winding mechanism 5 on the right side of the middle, the support rod 6 at the lower part is arranged near the winding mechanism 5 at the downstream part ( Figure 1 , 3 A slitting mechanism 8 driven by a hydraulic rod 7 is arranged directly above the two sets of winding mechanisms 5; a mounting frame 11 is arranged on the base 1 on the left side of the circular plate 4; a fixing plate 12 for fixing the hydraulic rod 7 is arranged on the mounting frame 11; a film roll 13 is also installed on the front side of the mounting frame 11 through a rotating shaft.

[0024] The winding mechanism 5 includes a mounting plate 52 arranged on the front side of the circular plate 4 and driven by a motor II51, the motor II51 is arranged on the rear side of the circular plate 4, a plurality of groups of screws 53 are arranged on the front end surface of the mounting plate 52, a winding disk 54 is arranged on the screw 53, the winding disk 54 includes an annular plate 542 sleeved on both ends of a cylinder 541, wherein a clamping groove 543 is axially arranged on the cylinder 541 between the two groups of annular plates 542, a through hole 544 for the screw 53 to pass through is also opened in the side wall of the cylinder 541, a nut 545 is screwed on the screw 53 outside the through hole 544, the cylinder 541 and the annular plate 542 are integrally arranged, the number of through holes 544 on the cylinder 541 is at least two groups, wherein the plurality of through holes 544 are evenly arranged in the side wall of the cylinder 541 outside the clamping groove 543.

[0025] The installation method of the winding reel is as follows: align the through hole 544 with the screw 53 to put the through hole 544 on the cylinder 541 on the screw 53, and then screw the nut 545 and the screw 53 together to lock and fix the winding reel 54 on the mounting plate 52. The disassembly steps are the opposite. Therefore, when a group of winding reels 54 wrapped with light strips needs to be replaced during use, the winding reel 54 can be removed by the steps opposite to the above, and then the new winding reel 54 can be replaced according to the above steps to continue winding the light strips. When the winding drum 54 is mounted on the mounting plate 52, the slot 543 on the winding drum 54 is opened and faces upward, which makes the winding drum 54 rotate with the mounting plate 52. When the winding drum 54 is mounted on the mounting plate 52, the slot 543 on the winding drum 54 is opened and faces upward, which makes the winding drum 54 rotate with the mounting plate 52. When the winding drum 54 is mounted on the mounting plate 52, the slot 543 on the right winding drum 54 is opened and faces upward, which makes the winding drum 54 rotate with the mounting plate 52.

[0026] When in use, the light strip processed by the braiding machine is passed through the bottom of the lower support rod 6, and at the same time, it is bent and buckled on the winding disk 54 in the winding mechanism 5 on the right side, and the winding disk 54 in the winding mechanism 5 on the right side is rotated counterclockwise to wind the light strip. When the light strip is fully wound, the motor I3 drives the circular plate 4 to drive the two sets of winding mechanisms 5 to rotate 180 degrees counterclockwise. At this time, the slitting mechanism 8 is located above the circular plate 4 to prevent it from affecting the rotation of the winding mechanism 5. Figure 3 As shown, the idle winding mechanism 5 is rotated to the right, and the winding mechanism 5 with the full light strip is rotated to the left. At this time, the hydraulic rod 7 drives the slitting mechanism 8 to move downward to cut the tight part of the light strip supported by the upper support rod 6. At the same time, the slitting mechanism 8 fixes the end of the light strip in the winding reel 54 in the right winding mechanism 5 to wind it. The film on the film roll 13 can be pulled out and connected to the winding reel 54 in the winding mechanism 5 with the full light strip on the left. At this time, the winding reel 54 in the winding mechanism 5 is 4 is driven to rotate by the corresponding motor II51 to wrap the film on the surface of the light strip to package it, then the slitting mechanism 8 is reset, the packaged light strip on the reel 54 in the left reel 5 is taken off and replaced with a new reel 54, when the reel 54 in the right reel 5 is fully wound, it is rotated in the above manner, and then the two sets of reel mechanisms 5 on the circular plate 4 are switched to continuously reel the light strip, and the slitting mechanism 8 is used to cut the light strip.

[0027] The slitting mechanism 8 includes a strip plate 81 connected to the hydraulic rod 7, and an inclined rod 82 and a positioning plate 83 are respectively arranged on both sides of the bottom of the strip plate 81. The inclined rod 82 is provided with a positioning shaft 84 located just above one side of the downstream winding disk 54, and the positioning plate 83 is driven by an electric push rod 85 at the top of the strip plate 81. The positioning plate 83 is located just above the top slot 543 of the cylinder 541 in the upstream winding disk 54. A cutting knife group 86 is also arranged at the bottom of the strip plate 81, which is directly opposite to the upper support rod 6. The inclined rod 82 and the positioning shaft 84 are located just above the corresponding two groups of annular plates 542. A circle of grooves 9 is arranged around the middle of the positioning shaft 84. The positioning shaft 84 in the groove 9 is covered with a bearing 10 with a diameter smaller than that of the positioning shaft 84, and the inclined rod 82 is fixedly connected to the top of the bearing 10.

[0028] like Figure 3 As shown, when the motor I3 rotates the winding reel 54 with the full light strip to the left through the circular plate 4, the idle winding reel 54 rotates to the right, and the light strip is just buckled on the cylinder 541 in the idle winding reel 54 on the right (as shown in FIG. Figure 3As shown), the light strip needs to be cut at this time, wherein the hydraulic rod 7 drives the strip plate 81 to drive the inclined rod 82, the cutting knife group 86, the electric push rod 85 and the positioning plate 83 to move downward, wherein the inclined rod 82 squeezes the light strip on the outer side of the downstream side, that is, the left winding reel 54, through the positioning shaft 84, so that it is tightly wound on the winding reel 54 to prevent the light strip from being loosened on the winding reel 54 after the end of the light strip is cut and cut, thereby affecting the packaging. At the same time, the strip plate 81 also drives the cutting knife group 86 to cut the light strip that is stretched straight by the upper support rod 6. In the above process, the electric push rod 85 simultaneously drives the positioning plate 83 to move downward to press against the right winding reel 54. On the light strip at the top of the middle cylinder 541, when the light strip is cut, the electric push rod 85 drives the positioning plate 83 to continue to move downward to squeeze the cut end of the light strip into the card slot 543, so that the end of the light strip is bent into a U shape and fixed in the card slot 543. When the positioning plate 83 is reset upward, the winding drum 54 is driven by the motor II51 in the right winding mechanism 5 to rotate counterclockwise to wind the light strip, and at the same time, the winding drum 54 on the left side that is fully wound with the light strip is driven by the motor II51 in the left winding mechanism 5 to continue to rotate. At this time, the film on the film roll 13 is pulled out and connected to the bottom of the winding drum 54 on the left side that is fully wound with the light strip. Then the winding drum 54 is driven by the motor II51 in the left winding mechanism 5 to rotate counterclockwise. The motor II51 in the left winding mechanism 5 is driven to rotate so as to wrap the film around the surface of the wound light strip for packaging. When the left winding disc 54 rotates counterclockwise, the end of the light strip will be driven to slide at the bottom of the positioning shaft 84, and the light strip sliding under the positioning shaft 84 will drive the positioning shaft 84 to rotate on the bearing 10, so that the inclined rod 82 in the slitting mechanism 8 can press the light strip on the left winding disc 54 through the bearing 10 and the positioning shaft 84 to prevent it from loosening, and can also reduce the resistance caused by the positioning shaft 84 to the sliding of the light strip. When the end of the light strip slides under the positioning shaft 84, the film has been partially covered with the light strip in the winding disc 54. After the light strip is wrapped and fixed, when the end of the light strip slides under the positioning shaft 84 and loses its squeezing force, the light strip will not become loose because some areas of the light strip are wrapped and fixed with a film. Then the wrapping work of the light strip on the take-up reel 54 is completed, and then the slitting mechanism 8 is moved up and reset. After the wrapping is completed on the left side, the take-up reel 54 is removed and replaced with a new one. When the light strip on the right side take-up reel 54 is wound, the motor I3 drives the circular plate 4 to drive the two sets of winding mechanisms 5 to rotate 180 degrees counterclockwise, and then repeat the above steps to continuously wind the light strip. The winding efficiency and effect of the light strip can be effectively guaranteed without stopping the tape machine, and the difficulty coefficient of operation is reduced.

[0029] The working principle of the present invention is as follows: the end of the light strip after the processing by the braiding machine is bent into a U shape and inserted into the card slot 543, wherein the end of the light strip inserted into the card slot 543 and bent into a U shape is stretched outward under the influence of its own elastic force and stuck in the card slot 543 and is not easy to slide out. At this time, when the motor II51 in the right winding mechanism 5 drives the winding disk 54 to rotate counterclockwise through the mounting plate 52 and the screw 53, it can smoothly wind the light strip on the cylinder 541 between the two sets of annular plates 542;

[0030] When the winding reel 54 in the right winding mechanism 5 is fully wound with the light strip, the motor I3 rotates the winding reel 54 with the full light strip to the left side through the circular plate 4, and when the idle winding reel 54 rotates to the right side, the hydraulic rod 7 drives the strip plate 81 to drive the inclined rod 82, the cutting knife group 86, the electric push rod 85 and the positioning plate 83 to move downward, wherein the inclined rod 82 squeezes the light strip on the outer side of the left winding reel 54 through the positioning shaft 84, so that it is tightly wound on the winding reel 54, and at the same time, the strip plate 81 also drives the cutting knife group 86 to cut the light strip that is stretched straight by the upper support rod 6. In the above process, the electric push rod 85 simultaneously drives the positioning plate 83 to move downward to press against the light strip on the top of the cylinder 541 in the right winding reel 54, and when the light strip is cut, the electric push rod 85 drives the positioning plate 83 to continue to move downward to squeeze the end of the cut light strip into the card The end of the light strip is bent into a U shape and fixed in the card slot 543. When the positioning plate 83 is reset upward, the motor II51 in the right winding mechanism 5 drives the right winding disk 54 to rotate counterclockwise to wind the light strip. At the same time, the film on the film roll 13 is used to package the light strip on the left winding disk 54 that continues to rotate and is driven by the corresponding motor II51. Then the slitting mechanism 8 is moved up and reset. After the left side wrapping is completed, the winding disk 54 is removed and replaced with a new one. When the light strip on the right winding disk 54 is wound, the motor I3 drives the circular plate 4 to drive the two sets of winding mechanisms 5 to rotate 180 degrees counterclockwise. Then the above steps are repeated to continuously wind the light strip. The winding efficiency and effect of the light strip can be effectively guaranteed without stopping the tape machine, and the difficulty coefficient of operation is reduced.

[0031] Embodiment 2:

[0032] A winding device for a braiding machine is basically the same as that of Example 1, except that a boss 14 facing the circular plate 4 is provided on the top of the base 1, and an arc-shaped notch 15 buckled on the bottom end of the circular plate 4 is provided on the boss 14. The arc-shaped notch 15 on the boss 14 supports the bottom end of the rotatable circular plate 4, thereby improving its stability and reducing the gravity compression of the circular plate 4 and the components mounted on its end surface on the output shaft of the motor I3. At the same time, a rechargeable battery pack can be installed on the circular plate 4 to power the motor II51, so as to prevent the circular plate 4 from driving the motor II51 to rotate infinitely counterclockwise when directly connected to the motor II51 through an external power supply, causing it to curl and pull the connecting wire between the external power supply and the motor II51.
