Description

Technical Field

[0001] This utility model relates to the field of single-component dispensing machines, and more particularly to a single-component dual-tube heating thermally conductive gel metering valve. Background Technology

[0002] A dispensing machine, also known as an adhesive applicator, glue applicator, glue applicator, or glue dispensing machine, is a specialized machine for controlling fluids and automatically applying them to the surface or interior of a product. It is primarily used in product manufacturing processes to precisely dispense, inject, coat, or drip adhesives, paints, and other liquids onto specific locations on each product. It can be used to apply dots, lines, circles, or arcs. With a wide range of applications, it can replace manual labor, enabling mechanized production. It can be operated as a standalone unit, offering simplicity, convenience, high speed, and precision, making it highly popular among users.

[0003] However, when using gels that require heat melting, the existing single-component dispensing machine with a single-tube structure requires time to heat melt the gel before it can continue working after using one tube of gel, which affects work efficiency. Also, the residual glue on the dispensing head and the work surface need to be paused before continuing to apply glue, which affects the construction quality. At the same time, the existing glue metering control is not very accurate. Too much glue is wasteful, and too little glue affects the quality and effect of the glue application.

[0004] Therefore, it is necessary to provide a single-component dual-tube heated thermally conductive gel metering valve to solve the above-mentioned technical problems. Utility Model Content

The components are connected by a sliding seal; the heating device 200 is respectively abutting and connected to the first glue cylinder 112 and the second glue cylinder 122 for heating both; the extrusion drive device 300 is used to drive the first extrusion device 110 and the second extrusion device 120 to extrude glue; the reversing valve 400 is connected to the first glue cylinder 112 or the second glue cylinder 122, and the reversing valve 400 is also connected to the metering device 500 and the glue dispensing device 600; the fixing device 700 is used to fix the extrusion device 100, the heating device 200, the extrusion drive device 300, the reversing valve 400, the metering device 500, the glue dispensing device 600, the photoelectric sensor 800, and the reversing valve drive device 900.

[0040] like Figure 1 , Figure 3 , Figure 5 , Figure 14As shown, specifically, the fixing device 700 includes a cylinder fixing seat 710, a first clamping member 720 for the rubber tube, a second clamping member 730 for the rubber tube, a housing 740, a fixing seat 750, and a limiting member 760. The first cylinder 111 and the second cylinder 121 are fixed by the cylinder fixing seat 710. The extrusion driving device 300 includes a first solenoid valve 310 and a second solenoid valve 320. The first solenoid valve 310 and the second solenoid valve 320 are respectively disposed on both sides of the machine and electrically connected to the first cylinder 111 and the second cylinder 121 respectively. Two control valves are respectively disposed on the housing 740 on both sides of the machine. The first solenoid valve 310 and the second solenoid valve 320 are connected by a cylinder switch 311. The first solenoid valve 310 and the second solenoid valve 320 are structurally axially symmetrical and are axially symmetrically positioned on both sides of the single-component dual-tube heated thermally conductive gel metering valve assembly. The second solenoid valve 320 includes a first solenoid valve interface 321, a second solenoid valve interface 322, a solenoid valve mounting plate 323, a solenoid valve body 324, and a solenoid valve mounting strip 325. The solenoid valve mounting plate 323 horizontally fixes the solenoid valve body 324, and the solenoid valve mounting strip 325 vertically fixes the solenoid valve body 324. The metering device 500 includes a servo motor 510 and a metering valve 520, which precisely control the amount of gel dispensed.

[0041] Because the metering device 500, consisting of the servo motor 510 and the metering valve 520, is provided, along with the extrusion device 100, consisting of two dispensing cylinders, the first dispensing cylinder 112 and the second dispensing cylinder 122, and both cylinders are heated, the problems of low work efficiency and inaccurate metering caused by the need to replace and reheat the dispensing cylinder after using a single-component gel cylinder are solved. The significant benefits are high work efficiency, high coating quality, and high accuracy in dispensing metering.

[0042] like Figure 4 As shown, the upper part of the heating device 200 consists of two parallel semi-circular tubes, which are used to clamp and transfer heat to the first rubber tube 112 and the second rubber tube 122, respectively; a heating cavity 23a is formed between the two semi-circular tubes of the heating device 200; a heating core 250 is provided in the heating cavity 23a for heating the heating cavity 23a; the lower part of the heating device 200 is a base with two round holes, which are used to support the first rubber tube 112 and the second rubber tube 122, respectively.

[0043] Specifically, the heating device 200 includes a connecting nozzle 210, a heating device body 230, two connecting seats 240, and a heating core 250. The connecting nozzle 210 connects to the heating cavity 23a at the center of the heating device body 230 and is installed at the upper end of the heating device body 230. The two connecting seats 240 are detachably installed on the base of the lower half of the heating device body 230. Setting the upper half of the heating device body 230 into two semi-circular tubes facilitates large-area contact between the heating device 200 and the first rubber sleeve 112 and the second rubber sleeve 122, enabling rapid heating and heat conduction.

[0044] like Figure 4 As shown, a temperature sensor 220 is also provided inside the heating chamber 23a to detect and control the real-time temperature of the heating chamber 23a.

[0045] like Figure 1 , Figure 2 , Figure 3 As shown, both the first clamping member 720 and the second clamping member 730 of the rubber tube are semi-circular tubes; the radii of the two semi-circular tubes of the first clamping member 720 and the second clamping member 730 are equal to the radii of the two semi-circular tubes of the heating device 200, respectively clamping the first rubber tube 112 and the second rubber tube 122; the first clamping member 720 and the second clamping member 730 of the rubber tube are detachably connected to the heating device body 230 of the heating device 200.

[0046] like Figure 1 , Figure 2 , Figure 3 As shown, preferably, the two sides of the heating device body 230 are connected to the first clamping member 720 and the second clamping member 730 of the rubber tube by hinges 721, and the middle is connected by a fixing bolt 722.

[0047] Specifically, the first clamping member 720 of the glue tube includes a hinge 721, a fixing bolt 722, and a clamping member body 723. The first clamping member 720 and the second clamping member 730 of the glue tube are arranged symmetrically along their structural axes. In use, the first glue tube 112 and the second glue tube 122 are placed on it and connected to the first cylinder 111 and the second cylinder 121 respectively. Then, the clamping member body 723 is rotated to clamp the first glue tube 112 and is fixed with the fixing bolt 722. The method for fixing the second glue tube 122 is the same as the method for fixing the first glue tube 112. Setting the clamping member body 723 and the body of the second clamping member 730 of the glue tube into a semi-circular tube state is beneficial for better fixing the first glue tube 112 and the second glue tube 122. When one of the first glue tube 112 and the second glue tube 122 is used up, the remaining one can continue to be used. At the same time, one of the used glue tubes can be replaced. Preheating can be done in advance, which helps to save time and improve the glue application quality.

The rear reversing valve 450 is disposed between the first-side fixing seat 460 and the second-side fixing seat 440 for the reversing valve, and the three are detachably connected, and is sleeved on the outer layer of the valve core 480. The valve core 480 has channels that are respectively connected to the rear reversing valve 450, the metering device 500, and the glue dispensing device 600. The valve core 480 is connected to the front intermediate reversing valve 420 through the rear reversing valve 450.

[0049] Specifically, the second-side reversing valve 430 has an L-shaped glue flow channel 431 vertically arranged at the center of its second-side reversing valve body 433, used to flow the glue in the second glue cylinder 122 into the glue inlet channel 422 of the front intermediate reversing valve 420. The body also has several second-side reversing valve fixing holes 432 for disassembling and connecting the front intermediate reversing valve 420. The first-side reversing valve 410 has a channel vertically arranged at its center, symmetrical to the glue flow channel 431 of the second-side reversing valve, used to flow the glue in the first glue cylinder 112 into the front intermediate reversing valve 410. The front intermediate reversing valve is located within the glue inlet channel 422 of the 20-inch intermediate reversing valve. The front intermediate reversing valve body 421 of the front intermediate reversing valve 420 is provided with a front intermediate reversing valve outlet channel 424 and a front intermediate reversing valve inlet channel 422 at its center.

The first side reversing valve 410 and the second side reversing valve 430 are respectively located on both sides of the front intermediate reversing valve 420.The adhesive flows from the first glue cartridge 112 into the first side reversing valve 410, and then from the first side reversing valve 410 into the glue inlet channel 422 and the glue outlet channel 424 of the front intermediate reversing valve in sequence. Then, it flows from the glue outlet channel 424 of the front intermediate reversing valve into the rear reversing valve 450. Alternatively, the adhesive flows from the second glue cartridge 122 into the second side reversing valve 430, and then from the glue flow channel 431 of the second side reversing valve into the glue inlet channel 422 of the front intermediate reversing valve in sequence. The glue flows from the front intermediate reversing valve outlet channel 424 into the rear reversing valve 450; the glue flows from the rear reversing valve 450 into the valve core 480, then through the metering valve 520 into the glue dispensing device 600, and finally flows out from the glue dispensing device 600 for dispensing; the first side fixing seat 460 of the reversing valve, the rear reversing valve 450, and the second side fixing seat 440 of the reversing valve are arranged in a straight line, and are aligned with the first side reversing valve 41. 0. The front intermediate directional valve 420 and the second side directional valve 430 are arranged in parallel; the rear directional valve 450 includes a side sealing ring 451, a valve core sleeve 452, a rear directional valve body 453, a lower directional valve bushing 454, a directional valve bushing assembly 455, an upper directional valve bushing 456, and an upper directional valve sealing gasket 457. The valve core sleeve 452 is sleeved on the outer layer of the valve core 480, and the rear directional valve body 453 is sleeved on the outer layer of the valve core sleeve 452. The rear directional valve body 453 and the valve core sleeve... Each of the 452 sections has a T-shaped hole with the same center line laid down vertically. The glue first flows from the glue outlet channel 424 of the front intermediate reversing valve into the horizontal glue channel of the rear reversing valve body 453, then into the horizontal glue channel of the valve core sleeve 452, and finally into the glue channel of the valve core 480. The rear reversing valve body 453 is detachably connected to the first side fixing seat 460 and the second side fixing seat 440 of the reversing valve with a side sealing ring 451 on each side. The rear directional valve body 453 is cubic or cuboid in shape, with five interconnected through holes on its five surfaces: a horizontal T-shaped hole and a vertical I-shaped hole, both of which are connected. The horizontal T-shaped hole is used to fit the valve core sleeve 452, and the remaining hole perpendicular to the I-shaped hole is connected to the glue outlet channel 424 of the front intermediate directional valve. The upper bushing 456 and the upper sealing gasket 457 of the directional valve are installed vertically on the upper part. The through hole is connected to the valve core transfer channel 482 of the valve core 480 and the metering valve 520. The lower bushing 454 of the reversing valve is installed below it, and the reversing valve bushing assembly 455 is installed between the front and the front intermediate reversing valve 420. The valve core sleeve 452 is cubic or cuboid in shape, with a T-shaped hole in the horizontal direction and an I-shaped hole in the vertical direction, and the two holes are connected. The holes of the valve core sleeve 452 and the holes of the rear reversing valve body 453 are on the same center line.

[0050] like Figure 14 As shown, the reversing valve drive device 900 is used to actuate the valve core 480; the reversing valve drive device 900 includes a drive motor 910 and a moving module 930, which are connected by a belt 920.

[0051] like Figure 11 , Figure 12 As shown, a strip-shaped mounting hole 484 is provided laterally at one end of the valve core 480, and the valve core 480 is slidably connected to the first side fixed seat 460 of the reversing valve through a valve core positioning pin 470 inserted into the strip-shaped mounting hole 484.

[0052] Specifically, the valve core body 481 of the valve core 480 has an L-shaped valve core extrusion channel 483 near the strip mounting hole 484, and an I-shaped valve core transfer channel 482 away from the strip mounting hole 484. The valve core extrusion channel 483 and the valve core transfer channel 482 are axially connected, and the valve core transfer channel 482 is connected to the metering valve 520. Adhesive first flows horizontally from the valve core transfer channel 482 into the valve core extrusion channel 483, then into the valve core transfer channel 482. The metering valve 520 forces the adhesive from the valve core transfer channel 482 into the adhesive dispensing device 600, whereby the adhesive finally flows out for dispensing. The distance the movable module 930 moves is precisely the distance between the center lines of the two holes in the valve core extrusion channel 483 and the valve core transfer channel 482. The dispensing device 600 includes, from top to bottom, a dispensing device fixing base 610, a dispensing receiving tube 620, a dispensing guide tube 630, a dispensing control tube 640, and a dispensing nozzle 650.

The driven wheel 931 is sleeved and fixed to one end of the lead screw 933. The lead screw 933 passes through both ends of the groove-shaped moving module body 932. The module slider 936 is installed in the groove of the moving module body 932 and sleeved on the outer layer of the lead screw 933. The toggle block 935 is detachably connected to the module slider 936 in the vertical direction. The toggle block 935 is inserted into the pusher 937. The pusher 937 is U-shaped or U-shaped and can move the two ends of the valve core 480 left and right.
