Description

Technical Field

[0001] The invention relates to the technical field of leather-wire lamp string production, and in particular to a production system for leather-wire lamp strings. Background Art

[0002] Leather wire light string, also known as PVC soft wire light string, is different from traditional LED light string. In traditional LED light string, each LED lamp unit includes a lamp holder and two leather wires connected to the lamp holder, and these LED lamp units are connected in series to form an LED light string.

[0003] During the production process of existing leather wire light strings, it is necessary to package the LED chips in the LED lamp beads, which usually requires an LED dispensing machine to perform dispensing and packaging. However, the existing LED dispensing machines have high requirements for dispensing accuracy. In order to improve the production efficiency of LED leather wire light strings, they are generally dispensed during the transportation process of the LED leather wire light strings. However, during dispensing, the LED leather wire light strings are too loose, which affects the dispensing effect. Moreover, a single dispensing mechanism can only dispense glue on one side of the LED leather wire light string. During production, multiple dispensing mechanisms are required to dispense glue on each side of the LED leather wire light string, which increases the equipment cost.

[0004] The patent document with the authorization announcement number CN115090483B discloses a fully automatic production equipment for linear LED leather wire lamps. When in use, the clamping mechanism and the tensioning mechanism respectively press and fix the two ends of the LED leather wire lamp string. At the same time, the tensioning mechanism not only presses and fixes the LED leather wire lamp string, but also plays a role in tightening it, ensuring the effect of glue dispensing. The second driving mechanism drives the glue dispensing mechanism to move to the position of the LED leather wire lamp string core to dispense glue on it; the rotating mechanism drives the first clamping block and the second clamping block to rotate, and then drives the LED leather wire lamp string to rotate, so that different sides of the LED leather wire lamp string face the glue dispensing mechanism. At the same time, the tensioning mechanism loosens and presses the LED leather wire lamp string to cooperate with the rotating mechanism to drive the LED leather wire lamp string to rotate. The glue dispensing mechanism dispenses glue on different sides of the LED leather wire lamp string core, thereby reducing the number of glue dispensing mechanisms and saving equipment costs. When the equipment dispenses glue on the LED leather wire lamp string, it is necessary to stop winding the LED leather wire lamp string, and it cannot achieve continuous production of LED leather wire lamp strings. Summary of the invention

[0005] The main purpose of the present invention is to provide a production system for a leather-wire light string that can realize continuous winding of the leather-wire light string during the glue dispensing process, thereby improving work efficiency. In order to achieve the above purpose, the technical solution provided by the present invention is:

[0006] The production system of the leather wire light string includes a winding device, a production table is arranged on one side of the winding device, and a guiding device, a drying device and a tensioning and gluing device are arranged on the production table in sequence.

[0009] Specifically, the drying device comprises a drying cylinder fixed on a production table, a plurality of infrared lamps are evenly distributed and fixed on the circumference of the inner edge of the drying cylinder, and a leather wire lamp string runs through the drying cylinder.

[0010] Specifically, an inverted U-shaped mounting frame is fixed on the production table, and the sleeve is fixed on the mounting frame.

[0011] Specifically, a limit bar parallel to the slide bar is fixed on the outer edge of the slide bar, the limit bar is slidably connected to the long groove in the sleeve, a stop block is fixed to one end of the slide bar in the sleeve, and the first spring is fixedly connected to the stop block.

After the two clamps clamp the leather wire light string and as the leather wire light string moves, the glue dispensing head dispenses glue to the position where the leather wire light string needs to be glued. The pressure sensor can detect the pressure applied by the first spring to it in real time. When the pressure value of the pressure sensor reaches the set value, the controller starts the electromagnet and releases the clamps, which can prevent the leather wire light string from being damaged by a large pulling force.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] like Figure 1-Figure 8 As shown, the production system of the leather wire light string includes a winding device, a production table 7 is arranged on one side of the winding device, and a guiding device, a drying device and a tensioning and gluing device are arranged on the production table 7 in sequence.

[0028] The winding device includes a winding frame 1, a winding roller 2 is rotatably arranged inside the winding frame 1, a first pulley 4 is concentrically fixed to the winding roller 2, a motor 3 is fixed to the winding frame 1, a second pulley 5 is concentrically fixed to the output shaft of the motor 3, the second pulley 5 is connected to the first pulley 4 through a belt 6, and the motor 3 is electrically connected to the controller.

[0029] The guide device includes a limiting roller 8 rotatably arranged on the production table 7, and the leather wire light string 30 passes around the upper end of the limiting roller 8. The limiting roller 8 has the function of limiting the leather wire light string 30 in the front and rear directions.

[0030] The drying device comprises a drying cylinder 9 fixed on a production table 7 , a plurality of infrared lamps 10 are evenly distributed and fixed on the inner circumference of the drying cylinder 9 , and a leather wire lamp string 30 runs through the drying cylinder 9 .

[0031] The tensioning and gluing device comprises two elastic telescopic parts fixed on the production table 7, and the two elastic telescopic parts are symmetrically arranged up and down.

[0032] The elastic expansion member includes a sleeve 12, and the axial direction of the sleeve 12 is parallel to the movement direction of the leather wire light string 30. Specifically, an inverted U-shaped mounting frame 11 is fixed on the production table 7, and the sleeve 12 is fixed on the mounting frame 11.

[0033] The slide bar 14 is slidably inserted in the sleeve 12, and a first spring 16 is fixed to one end of the slide bar 14 in the sleeve 12. Specifically, a stopper 15 is fixed to one end of the slide bar 14 in the sleeve 12, and the first spring 16 is fixedly connected to the stopper 15. A limit bar 17 parallel to the slide bar 14 is fixed to the outer edge of the slide bar 14, and the limit bar 17 is slidably connected to the long groove in the sleeve 12.

[0034] A pressure sensor 13 is fixed in the sleeve 12 , and the pressure sensor 13 is fixedly connected to the first spring 16 .

[0035] A vertical moving sleeve 18 is fixed to one end of the sliding rod 14 outside the sleeve 12, and a clamping plate 21 is elastically slidably arranged in the moving sleeve 18, and the clamping plate 21 is connected to the moving sleeve 18 through a second spring 20. The clamping plate 21 is made of iron, and the upper and lower clamping plates 21 are used to clamp the leather wire light string 30.

[0036] The opposite ends of the upper and lower clamping plates 21 are both provided with arc-shaped grooves, arc-shaped rubber pads 22 are fixed in the arc-shaped grooves, and the inner edges of the rubber pads 22 are processed with anti-slip patterns 23.

[0037] An electromagnet 19 is arranged in the movable sleeve 18 , and the pressure sensor 13 , the controller and the electromagnet 19 are electrically connected. After the electromagnet 19 is activated, the clamping plate 21 can move into the movable sleeve 18 and release the leather wire light string 30 .

[0038] A glue dispensing assembly is fixed on the upper movable sleeve 18 .

[0039] The dispensing assembly includes an electric telescopic rod 24 fixedly connected to the upper movable sleeve 18, a dispensing head 25 is fixed on the telescopic end of the electric telescopic rod 24, the inlet end of the dispensing head 25 is connected to a horizontal pipe 26, the horizontal pipe 26 is connected to the outlet of a delivery pump 28 through a hose 27, the inlet of the delivery pump 28 is connected to a glue barrel 29, and the glue barrel 29 is fixed on the production table 7. The delivery pump 28 is electrically connected to the controller.

[0040] The welding device welds the lamp beads to the leather wire, and the leather wire with the lamp beads passes through two clamping plates 21, a glue dispensing head 25, and a drying cylinder 9 in sequence for glue dispensing and drying, and then is wound onto a winding roller 2 to complete the production of the leather wire lamp string 30.

[0041] The leather wire light string 30 needs to be kept taut during the glue dispensing process to prevent the loose leather wire light string 30 from bending down when the glue dispensing head 25 contacts the light string 30, resulting in unqualified glue dispensing.

[0042] In the natural state, the second spring 20 pushes the clamping plate 21 to move closer to the leather wire light string 30, so that the upper and lower rubber pads 22 clamp the leather wire light string 30, and the anti-slip grooves 23 increase the friction between the rubber pads 22 and the leather wire light string 30. In this process, the motor 3 rotates through the second pulley 5, the belt 6 and the first pulley 4, so that the leather wire light string 30 is wound onto the winding roller 2, and the winding action of the leather wire light string 30 is maintained, ensuring that the welded leather wire light string 30 is always moved to the winding roller 2. Figure 1 Left side movement as shown.

[0043] Since the two clamping plates 21 tightly clamp the leather wire light string 30 through the two rubber pads 22, the moving leather wire light string 30 will drive the clamping plates 21 to move to the left, so that the moving sleeve 18 pushes the slide bar 14, so that the slide bar 14 squeezes the first spring 16. After the first spring 16 is compressed, it will give the moving sleeve 18 a reverse thrust, so that the moving plate drives the clamping plates 21 to move to the right, thereby tightening the leather wire light string 30. At this time, the electric telescopic rod 24 pushes the glue dispensing head 25 to contact the position of the leather wire light string 30 where glue is needed, and the delivery pump 28 delivers the glue in the glue barrel 29 to the leather wire light string 30 through the hose 27, the horizontal tube 26 and the glue dispensing head 25 for glue dispensing.

[0044] During the dispensing process, the dispensing head 25 moves with the movable sleeve 18, and the leather wire light string 30 is tightened, and the dispensing is completed during the movement. Compared with the traditional method of pausing the winding during dispensing, the dispensing process will not stop the winding, thereby improving the production efficiency of the leather wire light string 30.

[0045] As the leather wire light string 30 pulls the movable sleeve 18 through the splint 21, the compression of the first spring 16 gradually increases. When the pressure sensed by the pressure sensor 13 reaches a preset value, the pressure sensor 13 sends a signal to the controller, and the controller turns off the delivery pump 28. The electric telescopic rod 24 contracts to make the glue dispensing head 25 detach from the leather wire light string 30. At the same time, the pressure sensor 13 transmits the pressure signal to the controller, and the controller controls the electromagnet 19 to be energized. The electromagnet 19 is energized to adsorb the clamp 21 into the movable sleeve 18, and the second spring 20 is compressed, so that the rubber pad 22 is separated from the leather wire light string 30. At this time, the first spring 16 pushes the movable sleeve 18 and the clamp 21 to move to the right. During the recovery process of the first spring 16, the pressure on the pressure sensor 13 gradually decreases. When the pressure sensor 13 is no longer under pressure, the clamp 21 moves to the right side of the next glue point. At this time, the electromagnet 19 is powered off, and the second spring 20 is restored. The second spring 20 pushes the clamp 21 to clamp the leather wire light string 30 again, so as to tighten and dispense glue at the next glue point. When no glue is needed, the clamp 21 is separated from the leather wire light string 30 to avoid applying continuous tension to the leather wire light string 30, which causes the leather wire light string 30 to be torn off, thereby improving the safety of the production of the leather wire light string 30.

[0046] After the glue dispensing is completed, as the leather wire light string 30 moves, the glue dispensing position passes through the drying cylinder 9 and is irradiated and dried by the infrared lamp 10 therein, which can accelerate the solidification speed of the glue, so as to effectively reel up the leather wire light string 30.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
