Description

Technical Field

[0001] The invention belongs to the technical field of screw valves, and in particular relates to a screw valve and a glue dispensing device. Background Art

[0002] The screw valve is a type of positive displacement pump consisting of a screw and a stator, in which the screw and the stator form a sealed cavity. The working principle is to drive the screw to rotate through the rotation of the motor, so that the screw drives the fluid in the sealed cavity to be pushed out. It is widely used in the output of fluids in various viscosity ranges, especially high viscosity fluids, and is mainly used in industrial dispensing devices.

[0003] Among them, in the process of dispensing two-component glue, a screw valve is also used to quantitatively transport the glue. In the prior art, in the process of dispensing two-component glue, a pair of screw valves are usually used to independently transport the two-component glue, and the two-component glue is usually mixed in a glue delivery pipe. Although this method can mix the two-component glue, the effect of mixing the two-component glue by a single mixing and circulation method of the two-component glue is poor, and the two-component glue is prone to uneven mixing, which will not only result in poor subsequent dispensing effect, but also make the actual application effect of the screw valve poor.

[0004] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0050] like Figures 7 to 11 As shown, a transmission gear 306 is arranged inside the limit block 301, and the transmission gear 306 is fixedly sleeved on the outer side of the driving shaft 302. The transmission gear 306 plays a role of power transmission to the driving shaft 302.

[0051] like Figure 10 to Figure 11 As shown, a plurality of evenly distributed driven gears 307 are meshed on the outer side of the transmission gear 306. The auxiliary stirring shaft 309 is driven to rotate by the rotation of the plurality of driven gears 307.

[0052] like Figure 10 to Figure 11 As shown, a plurality of uniformly distributed limiting teeth 308 are integrally formed on the inner wall of the limiting block 301, and the limiting teeth 308 are meshed with the driven gear 307. Through the meshing of the limiting teeth 308 and the driven gear 307, the driven gear 307 can rotate around the transmission gear 306 in the limiting block 301 under the action of the limiting teeth 308 and the transmission gear 306.

[0053] like Figures 3 to 7 As shown, one end of the driving shaft 302 located in the mixing hose 1 is fixedly connected to a stirring and conveying screw 303. The two-component glue in the mixing hose 1 is mixed and stirred by controlling the rotation of the stirring and conveying screw 303. At the same time, the two-component glue stirred in the mixing hose 1 can be extruded and conveyed by the cooperation of the stirring and conveying screw 303 and the conveying hose 101.

[0054] Specifically, the stirring and conveying screw 303 cooperates with the conveying rubber tube 101 to form a sealed glue conveying cavity 304. The sealed glue conveying cavity 304 is pushed and moved to squeeze and convey the mixed two-component glue in the conveying rubber tube 101.

[0055] like Figure 1 As shown, a stirring motor 305 is fixedly connected to the top of the mixing hose 1, and the output shaft of the stirring motor 305 is drivingly connected to the driving shaft 302. The driving shaft 302 is driven to rotate by controlling the operation of the stirring motor 305.

[0056] Specifically, the amount of glue discharged from the rubber delivery hose 101 can be changed by controlling the rotation speed of the stirring motor 305 .

[0057] like Figures 3 to 9 As shown, the outer side of the stirring and conveying screw 303 is rotatably equipped with multiple sets of evenly distributed temperature-sensitive mixing components. The temperature-sensitive mixing components include multiple sets of auxiliary stirring shafts 309, and one end of the multiple sets of auxiliary stirring shafts 309 located in the limit block 301 is fixedly connected to the driven gear 307.

The two-component glue in the mixing hose 1 is mixed and stirred by the rotation of the pair of temperature-sensitive stirring rods 311. The two-component glue in the mixing hose 1 is mixed and stirred by the rotation of the temperature-sensitive stirring rods 311. At the same time, the temperature-sensitive stirring rods 311 can be bent and deformed according to temperature changes so that the mixing and stirring effect of the two-component glue in the mixing hose 1 by the temperature-sensitive stirring rods 311 can be adaptively adjusted, thereby improving the uniformity of the mixing and stirring of the two-component glue in the mixing hose 1.

[0060] like Figures 3 to 9 As shown, a fixed sleeve 312 is arranged between a pair of temperature-sensitive stirring rods 311, and the fixed sleeve 312 is fixedly sleeved on the outer side of the auxiliary stirring shaft 309. The fixed sleeve 312 plays a role in assembling and fixing the multiple groups of mixing blades 313.

[0061] like Figures 3 to 9 As shown, multiple groups of evenly distributed mixing blades 313 are fixedly connected to the outer side of the fixed sleeve 312. The rotation of the multiple groups of mixing blades 313 assists the temperature-sensitive stirring rod 311 to mix and stir the two-component glue in the mixing hose 1.

[0062] like Figures 3 to 9As shown, the end of the auxiliary stirring shaft 309 away from the driven gear 307 is fixedly connected with a turbulent stirring blade 314. The turbulent stirring blade 314 plays a turbulent stirring role on the two-component glue.

[0063] like Figures 1 to 5 As shown, the circulating liquid flow temperature control mechanism 4 is arranged outside the stirring and conveying screw 303, and the circulating liquid flow temperature control mechanism 4 includes a liquid inlet pipe 401, and the liquid inlet pipe 401 is fixedly assembled on one side of the mixing rubber hose 1. The heat exchange fluid 406 is conveyed into the rubber hose cooling cavity 402 through the liquid inlet pipe 401, so that the temperature of the two-component glue conveyed in the mixing rubber hose 1 and the conveying rubber hose 101 is controlled by the heat exchange fluid 406 circulating in the rubber hose cooling cavity 402 and the conveying cooling cavity 403.

[0064] like Figures 3 to 5 As shown, a hose cooling cavity 402 is provided in the mixing hose 1, the liquid inlet pipe 401 is communicated with the hose cooling cavity 402, and a delivery cooling cavity 403 is provided in the delivery hose 101, and the delivery cooling cavity 403 is communicated with the hose cooling cavity 402. The temperature of the two-component glue delivered in the mixing hose 1 and the delivery hose 101 is controlled by circulating a heat exchange fluid 406 in the hose cooling cavity 402 and the delivery cooling cavity 403, which not only ensures the smoothness of the delivery of the two-component glue in the mixing hose 1 and the delivery hose 101, but also improves the efficiency of mixing and stirring the two-component glue.

[0065] like Figures 1 to 3 As shown, one end of the liquid inlet pipe 401 away from the mixing hose 1 is fixedly connected to a circulating liquid pump 404. The operation of the circulating liquid pump 404 is controlled to extract and pressurize the heat exchange fluid 406 for transportation.

[0066] like Figures 1 to 3 As shown, a liquid storage tank 405 is arranged below the circulating liquid pump 404. The liquid storage tank 405 plays the role of storing and controlling the temperature of the heat exchange fluid 406.

[0067] Specifically, the liquid storage tank 405 is filled with a heat exchange fluid 406. The heat exchange fluid 406 is circulated in the hose cooling cavity 402 and the delivery cooling cavity 403 to control the temperature of the two-component glue delivered in the mixing hose 1 and the delivery hose 101. The delivery smoothness of the two-component glue is ensured by temperature control of the two-component glue. At the same time, the mixing uniformity of the two-component glue can be improved by ensuring the delivery smoothness of the two-component glue.

[0068] like Figures 1 to 6As shown, a liquid extraction pipe 407 is connected between the circulating liquid pump 404 and the liquid storage tank 405, and the liquid extraction pipe 407 is located below the liquid surface of the heat exchange fluid 406. It is convenient to extract and transport the heat exchange fluid 406 through the liquid extraction pipe 407. A return pipe 408 is fixedly connected to the side of the mixing hose 1 away from the liquid inlet pipe 401, and the return pipe 408 is connected to the hose cooling chamber 402. The fluid after heat exchange in the hose cooling chamber 402 is refluxed and discharged through the return pipe 408.

[0069] like Figures 1 to 6 As shown, one end of the return pipe 408 located in the liquid storage tank 405 is fixedly connected to a distribution pipe 409. The distribution pipe 409 distributes the heat exchange fluid 406 refluxed by the return pipe 408, thereby facilitating temperature control of the heat exchange fluid 406 after heat exchange.

[0070] like Figures 1 to 6 As shown, a plurality of evenly distributed flow nozzles 410 are fixedly connected to the bottom of the flow distribution pipe 409, and the plurality of flow distribution nozzles 410 are evenly arranged above the liquid surface of the heat exchange fluid 406. The heat exchange fluid 406 in the flow distribution pipe 409 is sprayed and discharged through the plurality of flow distribution nozzles 410.

[0071] In addition, a guide ring 411 is arranged above the limit block 301, and the guide ring 411 is rotatably assembled on the outer side of the driving shaft 302. The heat exchange fluid 406 is transported to the inner cooling channel 412 through the guide ring 411, so that the temperature of the stirring and conveying screw 303 is controlled by the heat exchange fluid 406 circulating in the inner cooling channel 412.

[0072] like Figures 3 to 5 As shown, an inner cooling channel 412 is provided in the driving shaft 302, and the guide ring 411 is in communication with the inner cooling channel 412. The temperature of the stirring and conveying screw 303 is controlled by circulating the heat exchange fluid 406 in the inner cooling channel 412, which can not only control the temperature of the two-component glue conveyed in the conveying hose 101, thereby ensuring the smoothness of conveying the two-component glue, but also improve the smoothness of the stirring and conveying screw 303 in stirring, mixing and conveying the two-component glue in the mixing hose 1 and the conveying hose 101.

[0073] like Figure 3 to Figure 4 As shown, a pair of conducting liquid pipes 413 are connected between the guide ring 411 and the hose cooling cavity 402. The conducting liquid pipes 413 are used to connect the guide ring 411 and the hose cooling cavity 402, so that the heat exchange fluid 406 in the hose cooling cavity 402 can be transported to the guide ring 411 along the conducting liquid pipes 413.

[0074] A glue dispensing device includes a screw valve.

[0075] During specific use, the two-component glue can be transported into the valve body 201 along the connecting hose 207 under the action of a pair of glue filling hoses 206, and the operation of the screw motor 203 is controlled to drive a pair of rotors 202 to rotate, and the two-component glue is transported into the mixing hose 1 through the cooperation of the rotor 202 and the screw motor 203.

[0076] Subsequently, the driving shaft 302 and the stirring and conveying screw 303 can be driven to rotate by controlling the operation of the stirring motor 305, and the two-component glue in the mixing hose 1 can be preliminarily mixed and stirred and extruded and conveyed by the rotation of the driving shaft 302 and the stirring and conveying screw 303. At the same time, the multiple sets of auxiliary stirring shafts 309 rotate synchronously with the rotation of the driving shaft 302 under the cooperation of the transmission gear 306, the driven gear 307 and the limit gear 308, and the rotation of the multiple sets of auxiliary stirring shafts 309 drives the stirring assembly plate 310 and the temperature-sensitive stirring rod 311 to rotate in the mixing hose 1, thereby facilitating the mixing and stirring of the two-component glue in the mixing hose 1.

[0077] In the process of mixing and stirring the two-component glue, the temperature-sensitive stirring rod 311 will bend and change shape as the temperature changes, and the mixing and stirring effect of the two-component glue in the mixing hose 1 can be adjusted by bending the temperature-sensitive stirring rod 311. In addition, the two-component glue in the mixing hose 1 is assisted in mixing and stirring by the rotation of the turbulent stirring blade 314 and the plurality of mixing blades 313.

[0078] Furthermore, by controlling the operation of the circulating liquid pump 404, the heat exchange fluid 406 in the liquid storage tank 405 can be transported along the liquid inlet pipe 401 to the hose cooling chamber 402. The temperature of the two-component glue can be regulated by circulating the heat exchange fluid 406 in the hose cooling chamber 402 and the delivery cooling chamber 403. This not only ensures the smoothness of the two-component glue transportation in the mixing hose 1 and the delivery hose 101, but also improves the efficiency of mixing and stirring the two-component glue.

[0079] In addition, the heat exchange fluid 406 can be transported to the inner cooling channel 412 under the action of the liquid conducting pipe 413 and the guide ring 411. The temperature of the stirring and conveying screw 303 can be regulated by the heat exchange fluid 406 circulating in the inner cooling channel 412, which can not only regulate the temperature of the two-component glue conveyed in the conveying hose 101, thereby ensuring the smoothness of conveying the two-component glue, but also improve the smoothness of the stirring and conveying screw 303 in stirring, mixing and conveying the two-component glue in the mixing hose 1 and the conveying hose 101.
