Description

Technical Field

[0001] This utility model relates to the field of liquid supply technology, and in particular to a glue injection pressurization device and a glue injection equipment for gas cylinder top cap. Background Technology

[0002] In industrial production, it is often necessary to apply adhesive to products for assembly and sealing. For example, in the production of gas cylinder bottom caps, adhesive is applied using an adhesive applicator. However, current adhesive applicators are directly connected to the adhesive tank via pipelines. Insufficient pressure can easily occur when pumping adhesive from the tank to the applicator, leading to uneven adhesive application on the gas cylinder bottom cap and reduced production quality. Therefore, there is an urgent need for a device that can improve the stability of adhesive supply, thereby improving the quality of adhesive application. Utility Model Content

[0003] The purpose of this utility model is to provide a glue injection pressurization device and a gas cylinder top cover glue injection equipment to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] The solution to the technical problem of this utility model is:

[0005] The glue injection pressurizing device includes: a pressurizing barrel with a piston inside, the piston dividing the interior of the pressurizing barrel into an air chamber and a liquid chamber along the vertical direction; an air inlet connected to the air chamber at the top of the pressurizing barrel; a liquid outlet connected to the liquid chamber at the bottom of the pressurizing barrel; a guide sleeve on the inner top side of the pressurizing barrel, the guide sleeve passing downward through the piston and extending into the liquid chamber; and a stirring mechanism disposed within the guide sleeve, the top of the stirring mechanism extending out of the pressurizing cover, and the bottom of the stirring mechanism extending into the liquid chamber.

[0006] This technical solution has at least the following beneficial effects: The piston divides the internal space of the pressure tank into an air chamber and a liquid chamber along the vertical direction. The air inlet can be connected to an external high-pressure air source to introduce high-pressure gas into the air chamber, while the liquid chamber is used to store the adhesive required for dispensing. When adhesive needs to be supplied to the external dispensing equipment, the external high-pressure air source pressurizes the air chamber through the air inlet, causing the piston to move downwards and pressurize the liquid chamber, thereby squeezing the adhesive in the liquid chamber from the outlet and sending it to the external dispensing equipment. Due to the high pressure in the liquid chamber and the high viscosity and poor fluidity of the adhesive, the dispensing process is more efficient. Deposition can easily occur in the liquid chamber. During use, the liquid chamber can be stirred by the stirring mechanism to promote the flow of the adhesive. The stirring mechanism and piston are separated by the guide sleeve to prevent the stirring mechanism from interfering with the piston and destroying the piston's role in separating the internal structure of the pressure tank, thus improving the stability of the internal structure. In this way, by inputting high-pressure air to pressurize and extrude the adhesive in the pressure tank, and using the stirring mechanism to stir the adhesive in the liquid chamber, the pressure required for adhesive injection can be provided, and the phenomenon of adhesive deposition in the high-pressure liquid chamber can be prevented, thereby improving the quality of adhesive injection.

[0007] As a further improvement to the above technical solution, the pressurizing tank is provided with a fixed tube extending in the vertical direction, and a liquid outlet is provided on the outer side of the bottom of the fixed tube. An opening is provided on the top side of the pressurizing tank corresponding to the position of the fixed tube, and a sealing component is provided on the top side of the pressurizing tank that can open or close the opening.

[0008] As a further improvement to the above technical solution, a movable tube is provided inside the fixed tube, and a connecting hole is provided on the outer bottom of the movable tube. An elastic element is provided between the bottom end of the movable tube and the bottom side of the pressurizing tank. When the sealing assembly closes the opening, the connecting hole and the liquid outlet are offset from each other; when the sealing assembly opens the opening, the connecting hole and the liquid outlet are directly opposite each other.

[0009] As a further improvement to the above technical solution, a stop plate is connected to the movable tube at the top side of the connecting hole. When the connecting hole and the liquid outlet are directly opposite each other, the stop plate abuts against the top side of the liquid outlet.

[0010] As a further improvement to the above technical solution, a connector head is provided at the top of the active tube.

[0011] As a further improvement to the above technical solution, the sealing assembly includes a rotating arm, a sealing cover, a connecting seat, and a locking seat. The connecting seat and the locking seat are respectively connected to the top side of the pressurizing barrel at positions on both sides of the opening. One end of the rotating arm is hinged to the connecting seat, the sealing cover is connected to the middle of the rotating arm, and the other end of the rotating arm is detachably connected to the locking seat. The sealing cover closes the opening.

[0012] As a further improvement to the above technical solution, a screw is provided on the top side of the locking seat, and a locking block is provided at the end of the rotating arm near the screw. The locking block is provided with a slot through which the screw can pass. A handwheel is connected to the screw, and the bottom end of the handwheel presses against the top side of the locking block.

[0013] As a further improvement to the above technical solution, a sealing gasket is provided on the bottom side of the sealing cover.

[0014] As a further improvement to the above technical solution, the stirring mechanism includes a rotating rod, a stirring paddle, and a rotating handle. The rotating rod is rotatably connected to the guide sleeve, the top of the rotating rod extends out of the pressure cover and is connected to the rotating handle, and the bottom of the rotating rod extends into the liquid cavity and is connected to the stirring paddle.

[0015] The gas cylinder top cap glue injection equipment includes a conveyor line, a glue injector located upstream of the conveyor line, a dryer located downstream of the conveyor line, and the aforementioned glue injection pressurization device. A glue delivery pipe is connected between the liquid outlet head and the glue injector.

[0016] This technical solution has at least the following beneficial effects: The conveyor line is used to input the product to be glued, such as the bottom cap of a gas cylinder. An external high-pressure air source is connected to the air inlet, and the glue dispenser is connected to the liquid outlet through the glue delivery pipe. When the product to be glued passes through the glue dispenser, high-pressure air is input into the glue dispensing pressurization device to pressurize and extrude the glue liquid. The dispensing liquid in the liquid chamber is stirred by the stirring mechanism, which can provide the glue dispenser with the pressure required for glue dispensing and prevent the glue liquid from easily depositing in the high-pressure liquid chamber, thereby improving the glue dispensing quality. After glue dispensing is completed, the product is then transported to the dryer by the conveyor line, where the dryer dries the product. This effectively improves the quality of glue dispensing on the product.

[0028] Reference Figure 1 and Figure 2 A glue injection pressurizing device includes a pressurizing tank 100 and a stirring mechanism. The pressurizing tank 100 has a piston 110 inside, which divides the interior of the pressurizing tank 100 vertically into an air chamber 120 and a liquid chamber 130. An air inlet 180 communicating with the air chamber 120 is located at the top of the pressurizing tank 100, and a liquid outlet 140 communicating with the liquid chamber 130 is located at the bottom of the pressurizing tank 100. A guide sleeve 150 is located on the inner top side of the pressurizing tank 100, passing downwards through the piston 110 and extending into the liquid chamber 130. Naturally, a sealing ring is provided between the piston 110 and the guide sleeve 150 to reduce the amount of glue entering the air chamber 120 from the liquid chamber 130. For example, a sealing ring is provided between the piston 110 and the guide sleeve 150. At least one sealing ring is provided inside the through hole to prevent the adhesive from entering the air chamber 120 through the gap between the piston 110 and the guide sleeve 150. The stirring mechanism is located inside the guide sleeve 150. The top of the stirring mechanism extends out of the pressure cover, and the bottom of the stirring mechanism extends into the liquid chamber 130. The part of the stirring mechanism outside the pressure cover is the power part, and the part of the stirring mechanism inside the liquid chamber 130 is the stirring part. During operation, the power part drives the stirring part to rotate, thereby stirring the adhesive in the liquid chamber 130. Naturally, a sealing structure is provided between the stirring mechanism and the inner side of the guide sleeve 150 to prevent the adhesive from entering the gap between the stirring mechanism and the guide sleeve 150. Similarly, a sealing ring can be provided between the stirring mechanism and the guide sleeve 150.

[0029] As described above, piston 110 divides the internal space of pressurized tank 100 into air chamber 120 and liquid chamber 130 along the vertical direction. Air inlet 180 can be connected to an external high-pressure air source to introduce high-pressure gas into air chamber 120. Liquid chamber 130 is used to store the adhesive required for dispensing. When adhesive needs to be supplied to the external dispensing equipment, the external high-pressure air source pressurizes air chamber 120 through air inlet 180, causing piston 110 to move downwards and pressurize liquid chamber 130. This forces the adhesive in liquid chamber 130 to be extruded from outlet 140 to the external dispensing equipment. Due to the high pressure in liquid chamber 130 and the high viscosity and poor fluidity of the adhesive... Deposition can easily occur in the liquid chamber 130. During use, the liquid chamber 130 can be stirred by the stirring mechanism to promote the flow of the adhesive in the liquid chamber 130. The guide sleeve 150 separates the stirring mechanism from the piston 110, which can prevent the stirring mechanism from interfering with the piston 110 when it moves, thus preventing the piston 110 from destroying its role in separating the internal structure of the pressure tank 100 and improving the stability of the internal structure. In this way, by inputting high-pressure air to pressurize and extrude the adhesive in the pressure tank 100, and using the stirring mechanism to stir the adhesive in the liquid chamber 130, the pressure required for adhesive injection can be provided, and the phenomenon of adhesive deposition in the high-pressure liquid chamber 130 can be prevented, thereby improving the quality of adhesive injection.

[0030] The pressurizing tank 100 includes a tank body and a tank cover. The tank cover is detachably connected to the top side of the tank body. For example, the tank cover is connected to the tank body by driving in multiple screws. At this time, the piston 110 is located inside the tank body, the guide sleeve 150 is connected to the bottom side of the tank cover, the air inlet head 180 is located on the tank cover, the liquid outlet head 140 is located at the bottom of the tank body, and the stirring mechanism is located on the tank cover. When internal maintenance is required, the tank cover can be directly removed from the tank body.

[0031] When it is necessary to add adhesive to the liquid chamber 130, the pressure tank 100 can be opened. However, the piston 110 needs to be removed before adhesive can be added, which is cumbersome. Therefore, in order to improve the convenience of adding adhesive to the liquid chamber 130, in this embodiment, a fixed tube 160 extending in the vertical direction is provided inside the pressure tank 100. An outlet 161 is provided on the outer side of the bottom of the fixed tube 160. An opening is provided on the top side of the pressure tank 100 corresponding to the position of the fixed tube 160. A sealing component that can open or close the opening is provided on the top side of the pressure tank 100. When in use, the sealing assembly is in the closed state of the top opening of the pressure tank 100. When it is necessary to add adhesive to the liquid chamber 130, the top opening of the pressure tank 100 is opened through the sealing assembly, and the adhesive replenishment pipe is connected to the fixed pipe 160 through the opening. Adhesive is pumped into the liquid chamber 130 from the fixed pipe 160. After completion, the sealing assembly is closed again. This allows for quick replenishment of adhesive into the liquid chamber 130, reduces the disassembly and assembly of the pressure tank 100, and improves the overall ease of operation.

[0032] In the above embodiment, during use, the opening is closed using a sealing assembly. At this time, the pressure inside the liquid chamber 130 is relatively high, and the sealing assembly is also subjected to significant pressure through the fixed tube 160. Therefore, the sealing assembly requires high pressure resistance and sealing performance. To improve the overall stability of use, in this embodiment, a movable tube 170 is provided inside the fixed tube 160. A connecting hole 171 is provided on the outer bottom of the movable tube 170. An elastic element 172 is provided between the bottom end of the movable tube 170 and the inner bottom side of the pressure tank 100. The elastic element 172 can be an elastic structure such as a spring or rubber. When the sealing assembly closes the opening, the connecting hole 171 and the liquid outlet 161 are offset from each other; when the sealing assembly opens the opening, the connecting hole 171 and the liquid outlet 161 are directly opposite each other. When supplying liquid, the sealing assembly closes the opening, presses down on the movable tube 170, and elastically squeezes the elastic element 172 through the movable tube 170, causing the connecting hole 171 on the movable tube 170 to be misaligned with the outlet 161 on the fixed tube 160. At this time, the pressure of the adhesive acts on the outside of the movable tube 170, effectively reducing the pressure transmitted to the sealing assembly. When it is necessary to replenish the liquid into the liquid chamber 130, the sealing assembly opens the opening on the top side of the pressure tank 100. The elastic force of the elastic element 172 can lift the movable tube 170 upward, so that the connecting hole 171 on the movable tube 170 is directly opposite the outlet 161 on the fixed tube 160. At this time, the pipe for replenishing the adhesive is connected to the movable tube 170, and the adhesive is output from the outlet 161 into the liquid chamber 130 through the connecting hole 171 on the movable tube 170. In this way, by utilizing the movement of the movable tube 170, the pressure on the sealing assembly when outputting the adhesive is cleverly reduced, thereby improving the overall structural stability.

[0033] To prevent the movable tube 170 from being excessively lifted upwards during the elastic recovery of the elastic element 172, the upward movement of the movable tube 170 can be limited. Specifically, a stop plate is connected to the movable tube 170 at the top side of the connecting hole 171. When the connecting hole 171 and the liquid outlet 161 are directly opposite each other, the stop plate abuts against the top side of the liquid outlet 161. When the sealing assembly is opened, the elastic force of the elastic element 172 lifts the movable tube 170 upwards, and the stop plate on the outside of the movable tube 170 also moves upwards. When the connecting hole 171 and the liquid outlet 161 are directly opposite each other, the stop plate abuts against the top side of the liquid outlet 161, thereby limiting the further upward movement of the movable tube 170 within the fixed tube 160 and ensuring that the connecting hole 171 and the liquid outlet 161 are accurately aligned.

[0034] To facilitate the connection between the external adhesive supply pipe and the movable pipe 170, a connector 173 is provided at the top of the movable pipe 170 in this embodiment. When it is necessary to replenish adhesive to the liquid chamber 130, the external adhesive supply pipe is connected to the connector 173, improving the convenience of liquid supply.

[0035] There are various ways for the sealing assembly to open or close the opening. For example, a cover can be used, which is directly threaded to the top side of the pressure tank 100. In order to further improve the locking and closing effect of the opening, in this embodiment, the sealing assembly includes a rotating arm 210, a sealing cover 220, a connecting seat 230, and a locking seat 240. The connecting seat 230 and the locking seat 240 are respectively connected to the top side of the pressure tank 100 at the positions on both sides of the opening. One end of the rotating arm 210 is hinged to the connecting seat 230, the sealing cover 220 is connected to the middle of the rotating arm 210, and the other end of the rotating arm 210 is detachably connected to the locking seat 240. The sealing cover 220 closes the opening. The rotating arm 210 rotates around the end hinged to the connecting seat 230. When it is necessary to supply glue to the outside, the other end of the rotating arm 210 is connected to the locking seat 240, which forms a force-saving lever and can increase the pressure of the sealing cover 220 to press and seal the opening. When it is necessary to open the opening, the other end of the rotating arm 210 is removed from the locking seat 240, and the rotating arm 210 can be rotated so that the sealing cover 220 no longer seals the opening.

[0036] There are several ways to detachably connect the rotating arm 210 and the locking seat 240. For example, the rotating arm 210 and the locking seat 240 can be fixed to each other by a snap-fit ​​connection. In this embodiment, a screw 250 is provided on the top side of the locking seat 240, and a locking block 260 is provided on the end of the rotating arm 210 near the screw 250. The locking block 260 is provided with a slot through which the screw 250 can pass. A handwheel 270 is connected to the screw 250, and the bottom end of the handwheel 270 presses against the top side of the locking block 260. When the rotating arm 210 needs to be connected to the locking seat 240, the rotating arm 210 drives the locking block 260 to approach the screw 250, so that the screw 250 enters the locking groove. Then, the handwheel 270 is turned to press down and fix the locking block 260. When the rotating arm 210 needs to be removed from the locking seat 240, the handwheel 270 is reversed to remove the downward pressure on the locking block 260, so that the locking block 260 can be rotated away from the screw 250, thereby opening the opening.

[0037] To improve the sealing performance between the sealing cap 220 and the movable tube 170, a sealing gasket is provided on the bottom side of the sealing cap 220 in this embodiment. When the sealing cap 220 closes its opening, the sealing gasket abuts against the top of the movable tube 170, thereby improving the sealing performance between the two.

[0038] The stirring mechanism can be electrically controlled to stir the adhesive in the liquid chamber 130, or it can be manually controlled. Specifically, the stirring mechanism includes a rotating rod 310, a stirring paddle 320, and a rotating handle 330. The rotating rod 310 is rotatably connected to the guide sleeve 150. The top of the rotating rod 310 extends out of the pressure cover and connects to the rotating handle 330. The bottom of the rotating rod 310 extends into the liquid chamber 130 and connects to the stirring paddle 320. Naturally, multiple sealing rings are provided between the rotating rod 310 and the guide sleeve 150 to prevent the adhesive from being forced into the space between the rotating rod 310 and the guide sleeve 150. When it is necessary to stir the adhesive, rotating the rotating handle 330 will drive the stirring paddle 320 to stir the adhesive via the rotating rod 310. The operation is convenient, the overall structure is simple, and it is beneficial to control production and manufacturing costs.

[0039] like Figure 3 As shown, the gas cylinder top cap adhesive injection equipment includes a conveyor line 410, an adhesive injector 420 located upstream of the conveyor line 410, a dryer 430 located downstream of the conveyor line 410, and the aforementioned adhesive injection pressurizing device. A glue delivery pipe connects the liquid outlet 140 to the adhesive injector 420. In practical applications, the conveyor line 410 is mainly used for product transportation and can be a belt conveyor. The adhesive injector 420 includes an adhesive injection head relatively fixed above the conveyor line 410. After the adhesive is fed into the adhesive injection head through the glue delivery pipe, it injects adhesive into the product transported along the conveyor line 410 below. The dryer 430 includes a drying hood relatively fixed downstream of the conveyor line 410 and a curing lamp located inside the drying hood. The drying hood has a channel through which the conveyor line 410 can pass. When the product is transported along the conveyor line 410, the curing lamp cures the adhesive on the product.

[0040] In this gas cylinder top cap glue injection equipment, the conveyor line 410 is used to input the product to be glued, such as the bottom cap of the gas cylinder. An external high-pressure air source is connected to the air inlet 180, and the glue injector 420 is connected to the liquid outlet 140 through the glue delivery pipe. When the product to be glued passes through the glue injector 420, the glue liquid is pressurized and squeezed out by inputting high-pressure air into the glue injection pressurizing device, and the glue liquid in the liquid chamber 130 is stirred by the stirring mechanism. This can provide the glue injector 420 with the pressure required for glue injection and prevent the glue liquid from easily depositing in the high-pressure liquid chamber 130, thereby improving the glue injection quality of the glue injector 420. After the glue injection is completed, it is then conveyed by the conveyor line 410 to the dryer 430, where the dryer 430 dries the product. This effectively improves the quality of glue injection on the product.
