Description

Technical Field

[0001] This utility model relates to the field of glue dispensing technology, and in particular to a glue balance monitoring and automatic emptying device. Background Technology

[0002] Glue balance monitoring monitors the amount of glue remaining in real time to keep track of usage, while automatic emptying removes glue automatically when the remaining amount reaches a certain level to prevent residue. The combination of these two features ensures accurate and efficient glue usage, reduces waste, and guarantees a smooth and stable production process.

[0003] A search revealed that the document with publication number "CN217440193U" mentions "an automatic fuel evacuation device, comprising an electric fuel pump and a filter assembly. The electric fuel pump has a controller for controlling the start and stop of the electric fuel pump according to a received external control signal; the filter assembly includes a filter element with a central hole for receiving filtered fuel, and the filter element includes a filter layer, a water condensation layer, and a screen layer arranged sequentially from the outside to the inside." In use, this invention can start or stop according to an external control signal, and the filter element of the automatic fuel evacuation device has a longer service life and better water removal effect.

[0004] However, controlling the amount of glue dispensed is difficult when using emulsified colloids such as latex. Traditional manual extrusion depends on the operator's pressure, which can easily lead to sudden changes in the amount of glue dispensed, making it difficult to supply a constant amount. Furthermore, the amount of glue required is not easy to control, which can easily result in using too much or too little glue, affecting product quality. Also, when it is necessary to drain the glue, incomplete drainage can easily occur.

[0005] Therefore, we provide a glue balance monitoring and automatic emptying device to solve the above problems. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a glue balance monitoring and automatic emptying device.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A glue balance monitoring and automatic emptying device includes a glue injection tube. An observation window is provided on the front side of the glue injection tube. A glue balance monitoring and automatic emptying component is installed on the inner side of the glue injection tube. The glue balance monitoring and automatic emptying component includes limiting grooves located on the outer sides of both the upper and lower ends of the glue injection tube. A supporting plastic bracket is installed on the outer side of the limiting groove. A glue tube top cover is installed on the top of the glue injection tube. A column limiting tube is welded to the top of the glue tube top cover. A threaded connection groove is provided on the outer side of the column limiting tube. A control button is connected to the lower side of the supporting plastic bracket. A threaded screw passes through the inner side of the column limiting tube. A glue extrusion plug is connected to the end of the threaded screw. A reflective sheet is provided on the outer side of the glue extrusion plug. A glue outlet is connected to the lower side of the glue injection tube.

[0009] As a further description of the above technical solution:

[0010] The supporting plastic card holder and the limiting groove are connected by a card slot, and there is a one-to-one correspondence between the supporting plastic card holder and the limiting groove.

[0011] As a further description of the above technical solution:

[0012] A rotation controller is installed on the outside of the supporting plastic bracket, and a rotation motor is installed on the upper side of the rotation controller. A hexagonal shaft is connected to the upper slot of the rotation motor, and a threaded disc is connected to the upper side of the hexagonal shaft. The threaded disc and the hexagonal shaft cooperate with the rotation motor to form a rotation structure.

[0013] As a further description of the above technical solution:

[0014] The threaded disc and the threaded screw are connected by a thread. The threaded disc and the threaded screw are connected through a threaded connection groove outside the column limiting tube. The threaded disc drives the threaded screw to move up and down along the column limiting tube.

[0015] As a further description of the above technical solution:

[0016] The threaded screw and the column limiting tube have the same diameter, and the length of the threaded screw is the same as the total length of the glue injection tube and the column limiting tube.

[0017] As a further description of the above technical solution:

[0018] The extrusion plug and the injection tube are connected by a groove, and the extrusion plug and the injection tube fit tightly together. The extrusion plug is made of rubber, and the injection tube has a conical structure.

[0019] As a further description of the above technical solution:

[0020] A photosensitive card is connected to the middle slot on the outer side of the glue injection tube. A photosensitive signal controller is connected to the outer side of the photosensitive card. A laser spotlight is installed on the upper side of the photosensitive signal controller. The laser spotlight and the reflector are connected by a light reflection structure. The photosensitive signal controller and the rotation controller are electrically connected.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This utility model utilizes a glue balance monitoring and automatic emptying component. When needed, the operator can hold the glue injection tube, ensuring it remains vertical and stable via a supporting plastic bracket. Then, pressing the control button activates the rotary controller, which in turn controls a rotary motor that drives a threaded disc via a hexagonal shaft. The hexagonal structure of the shaft provides enhanced stability to the threaded disc. As the disc rotates, it drives a threaded screw through a threaded connection groove outside the column limiting tube, allowing the screw to move up and down within the tube. This causes the extrusion plug to move downwards, ensuring a tight fit between the plug and the injection tube. This prevents glue residue from remaining on the inner wall of the tube during extrusion, effectively squeezing and discharging the glue and providing better glue supply control.

[0023] 2. This utility model uses a glue balance monitoring and automatic emptying component. Based on the remaining glue limit or glue usage limit, the photosensitive signal controller is positioned at a suitable location outside the observation window via a photosensitive card. At this time, the light emitted by the laser spotlight will penetrate the observation window. When the glue extrusion plug descends to a certain space, the light emitted by the laser spotlight is reflected back to the photosensitive signal controller by the reflector, triggering a signal feedback to the rotation controller, which automatically stops the rotation of the threaded disc. When it is necessary to empty the glue, simply adjust the position of the photosensitive card or remove the photosensitive card to achieve the functions of glue balance monitoring and automatic emptying.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-6 As shown, this utility model provides a technical solution: a glue balance monitoring and automatic emptying device, including a glue injection tube 1, an observation window 2 provided on the front side of the glue injection tube 1, a glue balance monitoring and automatic emptying component 3 installed on the inner side of the glue injection tube 1, the glue balance monitoring and automatic emptying component 3 including limiting grooves 301 both disposed on the outer sides of the upper and lower ends of the glue injection tube 1, a supporting plastic bracket 302 installed on the outer side of the limiting grooves 301, and a glue tube top cover 307 installed on the top of the glue injection tube 1. A column limiting tube 308 is welded to the top of the cover 307. A threaded connection groove 309 is provided on the outside of the column limiting tube 308. A control button 310 is connected to the lower side of the supporting plastic card holder 302. A control button 311 is installed on the outside of the control button 310. A threaded screw 312 passes through the inside of the column limiting tube 308. A glue extrusion plug 313 is connected to the end of the threaded screw 312. A reflector 314 is provided on the outside of the glue extrusion plug 313. A glue outlet 4 is connected to the lower side of the glue injection tube 1.

[0033] Furthermore, the supporting plastic bracket 302 and the limiting groove 301 are connected by a slot, and the supporting plastic bracket 302 and the limiting groove 301 correspond one-to-one. When needed, the supporting plastic bracket 302 is inserted into the limiting groove 301. In this way, when glue needs to be injected, the plate connected to the supporting plastic bracket 302 can stably fix the glue injection tube 1. And when the glue injection tube 1 needs to be removed, the glue injection tube 1 can be removed from the supporting plastic bracket 302 to perform the glue replacement operation.

[0034] Furthermore, a rotation controller 303 is installed on the outer side of the supporting plastic bracket 302. A rotation motor 304 is installed on the upper side of the rotation controller 303. A hexagonal shaft 305 is connected to the upper slot of the rotation motor 304. A threaded disc 306 is connected to the upper side of the hexagonal shaft 305. The threaded disc 306 and the hexagonal shaft 305, together with the rotation motor 304, form a rotation structure. When needed, the operator can hold the glue injection tube 1 and ensure that the glue injection tube 1 is vertical and does not move by supporting the plastic bracket 302. Then, the operator presses the control button 311 to control the rotation controller 303 to rotate. The rotation controller 303 then controls the rotation motor 304 to drive the threaded disc 306 to rotate through the hexagonal shaft 305. The hexagonal structure of the hexagonal shaft 305 can provide stronger stability for the threaded disc 306.

[0035] Furthermore, the threaded disc 306 and the threaded screw 312 are connected by threads. The threaded disc 306 and the threaded screw 312 are connected through the threaded connection groove 309 outside the column limiting tube 308. The threaded disc 306 drives the threaded screw 312 to move up and down along the column limiting tube 308. As the threaded disc 306 rotates, it drives the threaded screw 312 to rotate passively through the threaded connection groove 309 outside the column limiting tube 308, so that the threaded screw 312 can move up and down inside the column limiting tube 308 to squeeze and discharge the glue in the glue injection tube 1, providing better glue supply control.

[0036] Furthermore, the threaded screw 312 and the column limiting tube 308 have the same diameter, and the length of the threaded screw 312 is the same as the total length of the glue injection tube 1 and the column limiting tube 308. When the threaded screw 312 moves up and down to squeeze, since the length of the threaded screw 312 is fixed, when the threaded screw 312 reaches the bottom, it will stop moving due to its own length limitation, and at this time the glue will be completely squeezed out.

[0037] Furthermore, the extrusion plug 313 and the injection tube 1 are connected by a groove, and the extrusion plug 313 and the injection tube 1 are tightly fitted together. The extrusion plug 313 is made of rubber, and the injection tube 1 has a conical structure. When the glue is supplied, as the threaded screw 312 moves downward, it drives the extrusion plug 313 downward. At this time, the extrusion plug 313 and the injection tube 1 are tightly fitted together, ensuring that there is no glue residue on the inner wall of the injection tube 1 during the extrusion process. The extrusion plug 313 is conical, so it can be submerged as much as possible in the conical space of the glue outlet 4 at the bottom of the injection tube 1, ensuring that the glue is completely discharged at the end.

[0038] Furthermore, a photosensitive card 315 is connected to the middle slot on the outer side of the dispensing tube 1. A photosensitive signal controller 316 is connected to the outer side of the photosensitive card 315. A laser spotlight 317 is installed on the upper side of the photosensitive signal controller 316. The laser spotlight 317 and the reflector 314 form a light reflection structure. The photosensitive signal controller 316 is electrically connected to the rotation controller 303. According to the remaining glue amount required for dispensing, or the glue dispensing amount limit, the photosensitive signal controller 316 is secured by the photosensitive card 315. When the laser spotlight 317 is positioned at a suitable location outside the observation window 2, the light emitted by the laser spotlight 317 will penetrate the observation window 2. When the glue plug 313 descends to a certain space, the light emitted by the laser spotlight 317 is reflected back to the photosensitive signal controller 316 by the reflector 314, triggering a signal feedback to the rotation controller 303, which automatically stops the rotation of the threaded disc 306. When it is necessary to drain the glue, simply adjust the position of the photosensitive card 315 or remove the photosensitive card 315 to achieve the function of glue balance monitoring and automatic drainage.

[0039] Working principle: When needed, fix the supporting plastic bracket 302 to the usage position according to the usage situation, or use the glue injection tube 1 directly by hand. Then, clip the supporting plastic bracket 302 onto the outside of the limiting groove 301 for fixation. After preparation, fix the glue tube top cover 307 to the top of the glue injection tube 1, and insert the glue extrusion plug 313 into the glue injection tube 1. At the same time, fix the threaded disc 306 into the hexagonal shaft 305 on the rotary motor 304, and fix it with external bolts. The outer periphery of the threaded disc 306 is clipped into the threaded connection groove 309 outside the column limiting tube 308, and contacts the thread on the surface of the threaded screw 312. After preparation, according to the amount of glue used, clip the light sensor card 315 to the appropriate position on the outside of the observation window 2. Finally, the operator holds the glue injection tube 1 and presses the control button card 3. The control button 311 on the outside controls the threaded disc 306 to start rotating. When the threaded disc 306 rotates, it drives the threaded screw 312 synchronously. When the threaded screw 312 rotates, it drives the extrusion plug 313 downward, squeezing the glue from the glue outlet 4 until the reflector 314 outside the extrusion plug 313 reflects the light of the laser spotlight 317, indicating that the preset position has been reached. At this time, the light sensor signal controller 316 will transmit the light signal to the rotation controller 303, terminating the operation of the rotation motor 304. When it is necessary to empty, the light sensor card 315 is removed, and the threaded disc 306 is rotated continuously until the threaded screw 312 is rotated to the end, and the extrusion plug 313 is inserted into the glue outlet 4 to achieve the automatic emptying effect. This completes the use process of a glue balance monitoring and automatic emptying device.
