Description

Technical Field

[0001] The utility model relates to a novel pressure injection type glue dispensing and filling machine, and relates to the technical field of glue filling equipment. Background Art

[0002] The glue filling machine is an automated device that can conveniently fill the glue in the glue barrel into different syringes, which can greatly improve the glue filling efficiency.

[0003] The quantitative dispensing of existing glue filling machines is mostly controlled by the stroke of a cylinder or a motor. For example, the patent technology with announcement number CN219409242U discloses a glue quantitative dispensing machine, including a tank body, a cleaning component is slidably connected to the inside of the tank body, a threaded hole is opened on the top surface of the tank body, a threaded rod is threadedly connected to the inside of the threaded hole, a cover plate is threadedly connected to the surface of the threaded rod, a hose is fixedly connected to the bottom surface of the tank body, a peristaltic component is clamped on the surface of the hose, a first fixed rod is fixedly connected to the bottom surface of the peristaltic component, and a base is fixedly connected to the bottom surface of the fixed rod. The glue quantitative filling machine, through the setting of the cleaning component, the hydraulic pump is connected to the external power supply, and begins to expand and contract, driving the rubber ring fixedly connected to the side of the disc to move. The rubber ring scrapes the inner wall of the tank body and presses the residual glue into the hose fixed to the bottom of the tank body, thereby achieving the effect of keeping the inside of the tank body clean and avoiding glue waste when using the filling machine. This scheme is to adjust and control the glue output through the cooperation of the servo motor and the peristaltic component, thereby achieving the effect of convenient and fast control of the glue output and improving the efficiency of the glue quantitative filling action. However, this control method cannot achieve precise quantification and lacks a monitoring device. At the same time, since the rubber hose is long during filling, there is glue waste. Therefore, a filling device that can both accurately quantify and reduce glue waste is proposed to solve the problems existing in the prior art. Utility Model Content

[0008] Furthermore, a rubber tube jig lifting cylinder 18 is provided on the back of the fixed back plate 1, and a connecting plate 19 is provided at the bottom of the cylinder rod of the rubber tube jig lifting cylinder 18, and one end of the connecting plate 19 passes through the slide groove on the fixed back plate 1 and is connected to the rubber tube jig 8.

[0009] Furthermore, a clamping block 20 is disposed on the back of the rubber cylinder fixture 8 , a slide plate 21 is disposed on the fixed back plate 1 , and clamping block sliding grooves are disposed on both sides of the slide plate 21 to cooperate with the clamping block 20 .

[0013] Furthermore, an electric control panel 23 is also provided on one side of the fixed back plate 1 .

[0014] The working principle of the utility model is as follows: before filling glue, the syringe piston 13 is first inserted into the syringe 24, and then the syringe 24 is fixed on the rubber barrel fixture 8, and the rubber barrel fixture lifting cylinder 18 is controlled to work through the electronic control panel 23, and the rubber barrel fixture 8 is controlled to move downward, so that the syringe glue inlet and the glue outlet 15 are tightly connected.

At this time, the lifting cylinder 18 of the glue barrel fixture is controlled to rise, so that the glue barrel fixture 8 rises, driving the syringe 24 to separate from the glue outlet nozzle 15. At this time, due to the negative pressure of the glue, the syringe piston 13 is adsorbed in the syringe 24, and the piston cylinder 4 is controlled to retract the piston push rod and separate it from the syringe 24, so that the syringe 24 can be taken out from the glue barrel fixture 8, and the empty syringe 24 can be put in again to start a new glue filling operation.

[0023] See also Figure 1-5As shown, the technical solution adopted in this specific embodiment is: it includes a fixed back plate 1, a feed box 2, and an electronic control chassis 3. The feed box 2 is arranged on the electronic control chassis 3, and the fixed back plate 1 is arranged on the feed box 2. A quantitative module is movably arranged on the fixed back plate 1, a feed barrel 5 is arranged in the feed box 2, and a lifting cylinder 17 is arranged in the electronic control chassis 3. The quantitative module includes a piston cylinder 4, a slide assembly 9, a high position sensor 10, a slide upper limit sensor 11, and a slide lower limit sensor 22. The upper part of the piston cylinder 4 is arranged in a protective shell on the fixed back plate 1, the high position sensor 10 is arranged on the upper part of the piston cylinder 4, the slide upper limit sensor 11 is arranged on the upper part of the fixed back plate 1, and the slide lower limit sensor 22 is arranged in the middle part of the fixed back plate 1. A rubber cylinder fixture 8 is arranged below the quantitative module, and the lower part of the piston cylinder 4 is connected to the rubber cylinder fixture 8. In the traditional filling machine structure, the rubber cylinder fixture is usually fixed, and the glue is poured. The mechanism moves to fill glue, so it is easy to have inaccurate glue filling quantity, and the traditional glue filling mechanism needs to use more hoses to connect the glue filling, and some glue remains in the hose, resulting in glue waste. Therefore, in this embodiment, multiple sensors are used to control the quantitative module, among which the upper and lower slide limit sensors control the glue filling starting point and the maximum glue filling amount. When the slide assembly is at the lowest point, that is, after the glue cylinder is installed, the piston push rod of the piston cylinder moves downward and presses against the syringe piston. At this time, the lower limit sensor of the slide sends a signal, and glue filling can start, while the high position sensor and the upper limit sensor of the slide both detect and control the maximum glue filling amount. When the glue filling amount reaches the maximum set value, the above two sensors will be triggered to control the equipment to stop working. Double detection ensures that the glue filling will not exceed the maximum amount. At the same time, the glue filling amount can be accurately set by the sensor set on the quantitative module, and accurate quantitative glue filling can be performed. Specifically:

[0024] The slide assembly 9 includes a quantitative sensor 91, a quantitative adjustment motor 92, and a lifting screw 93. The quantitative adjustment motor 92 is arranged on the top of the fixed back plate 1. One end of the lifting screw 93 is connected to the output end of the quantitative adjustment motor 92, and the other end is movably connected to the fixed back plate 1. The quantitative sensor 91 is threadedly connected to the lifting screw 93, and a fixed bracket is provided around the piston cylinder 4. The quantitative sensor is used to set the specific glue filling amount and is lifted and lowered by the quantitative adjustment motor. When the quantitative sensor moves a set distance, a stop signal is issued to control the quantitative adjustment motor to stop working, thereby realizing quantitative glue filling.

[0025] More specifically, a quantitative pointer 94 is provided on the fixing bracket, and the quantitative pointer 94 is exposed to the mounting housing outside the piston cylinder 4. The real-time situation of glue pouring can be clearly understood through the quantitative pointer.

[0026] To be more specific, a rubber cartridge jig lifting cylinder 18 is provided on the back side of the fixed back plate 1, and a connecting plate 19 is provided at the bottom of the cylinder rod of the rubber cartridge jig lifting cylinder 18. One end of the connecting plate 19 passes through the slide groove on the fixed back plate 1 and is connected to the rubber cartridge jig 8. A clamping block 20 is provided on the back side of the rubber cartridge jig 8, and a slide plate 21 is provided on the fixed back plate 1. Clamping block slide grooves are provided on both sides of the slide plate 21 to cooperate with the clamping block 20. The lifting cylinder of the rubber cartridge jig can control the lifting of the rubber cartridge jig to realize the connection and separation of the syringe and the feeding end. The cooperation between the clamping block and the slide plate makes the entire rubber cartridge jig a slider structure, which can be lifted and lowered more smoothly.

[0027] To be more specific, a fixed plate 14 is provided on the fixed back plate 1, a glue nozzle 15 is provided on the top of the fixed plate 14, the glue nozzle 15 corresponds to the position of the glue barrel fixture 8, a material pipe joint 16 is provided at the bottom of the fixed plate 14, and the material pipe joint 16 is connected to the glue nozzle 15. In this embodiment, the quantitative module, the glue barrel fixture and the glue nozzle are in the same vertical position. When filling glue, the glue barrel fixture moves downward, so that the syringe can be directly aligned and connected with the glue nozzle without using too many hoses to connect, thereby reducing glue waste.

[0028] To be more specific, a glue injection valve 7 is provided on the top of the feed box 2, and the top of the glue injection valve 7 is connected to the material pipe joint 16 through a hose. A pressure plate 6 is provided inside the feed box 2, and the pressure plate 6 matches the material barrel 5. A material pipe is provided in the middle of the pressure plate 6 and passes through the feed box 2 and is connected to the glue injection valve 7. In this embodiment, the glue injection valve is connected to the material pipe joint through a shorter hose for feeding, and the bottom is also connected to the pressure plate through a shorter material pipe. When the feed barrel rises and contacts the pressure plate to press and feed the material, the stroke is shorter, the speed is faster, and the waste of glue is reduced.

[0029] More specifically, an electric control panel 23 is provided on one side of the fixed back plate 1, through which the debugging of each step of the process and the formal glue filling operation can be carried out.

[0030] The working principle of the utility model is as follows: before filling glue, the syringe piston 13 is first inserted into the syringe 24, and then the syringe 24 is fixed on the rubber barrel fixture 8, and the rubber barrel fixture lifting cylinder 18 is controlled to work through the electronic control panel 23, and the rubber barrel fixture 8 is controlled to move downward, so that the syringe glue inlet and the glue outlet 15 are tightly connected. At this time, the downward pressure sensor arranged on the rubber barrel fixture lifting cylinder 18 sends a stop signal according to the stroke, and the rubber barrel fixture lifting cylinder 18 stops working, and then the quantitative adjustment motor 92 is controlled to work, driving the quantitative sensor 91 to move downward, and the piston cylinder 4 works synchronously when the quantitative adjustment motor 92 works, and the stroke of the syringe piston 13 is the same as the stroke of the quantitative sensor 91, and the setting position of the upper and lower slide limit sensors is the stroke range of the quantitative sensor 91, and the position state of the quantitative sensor 91 is externally indicated by the quantitative pointer 94. After the amount of glue to be filled is set, the position of the quantitative sensor 91 is adjusted, so that the syringe piston 13 extends into the syringe 24 and is placed on the top At the injection port position, the lower limit sensor 22 of the slide sends a signal, and the quantitative adjustment motor 92 stops working. At this time, glue injection can be started, and the lifting cylinder 17 is started to push the feed barrel 5 up. Glue enters the injection valve 7 from the material pipe in the middle of the pressure plate 6. The injection valve 7 controls the amount of glue discharged. Glue enters the glue outlet nozzle 15 from the material pipe joint and enters the syringe 24 and pushes the syringe piston 13 to rise. The quantitative pointer 94 moves upward synchronously to display the glue injection situation. When the set glue injection amount is reached, the quantitative sensor 91 sends a stop signal, and the quantitative adjustment motor 92 stops working to complete the quantitative filling of glue. At this time, the lifting cylinder 18 of the glue barrel fixture is controlled to rise, so that the glue barrel fixture 8 rises, driving the syringe 24 to separate from the glue outlet nozzle 15. At this time, due to the negative pressure of the glue, the syringe piston 13 is adsorbed in the syringe 24, and the piston cylinder 4 is controlled to retract the piston push rod and separate it from the syringe 24, so that the syringe 24 can be taken out from the glue barrel fixture 8, and the empty syringe 24 can be put in again to start a new glue filling operation.
