Description

Technical Field

[0001] The utility model relates to a quantitative hot melt adhesive supply device, belonging to the technical field of adhesive supply equipment. Background Art

[0002] In existing industrial production, glue injection equipment is often needed to inject some colloid fluid into the working surface or some small gaps. The glue injection equipment must be supplied with glue by a glue supply device to ensure the continuous progress of the glue injection work.

[0003] The existing glue supply equipment is a single piston pump inserted into the glue barrel, and a pressure plate that continuously presses down is set on the glue surface. The glue is transported to the glue injection device through the feeding pipeline through the pressure of the pressure plate and the reciprocating motion of the piston pump. The glue supply equipment has no quantitative function, so there is a problem of excessive or insufficient glue supply. In view of the above shortcomings, the utility model proposes a hot melt adhesive quantitative glue supply equipment. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a hot melt adhesive quantitative glue supply device to solve the existing problems.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized by the following technical scheme: a hot melt adhesive quantitative glue supply device, comprising a frame, a quantitative tank group arranged in the middle of the frame, and a supply mechanism vertically arranged at the upper end of the frame, and the lower end of the supply mechanism is movably sleeved in the tank body cavity of the quantitative tank group, a controller is arranged on the right side of the frame, and the quantitative tank group, the supply mechanism and the controller are electrically connected;

[0006] The supply mechanism includes a servo telescope, a pressure sensor arranged at the lower end of the servo telescope, an adjustment pressure seat arranged vertically on the bottom surface of the pressure sensor, and an adjustment pressure rod group threadedly connected to the lower end of the adjustment pressure seat. The lower end of the adjustment pressure rod group is provided with an extrusion seat, and the extrusion seat is provided with a sealing pressure pad.

[0007] A further improvement is that the quantitative tank group includes a quantitative tank, a quantitative meter arranged on the front surface of the quantitative tank body, a rubber inlet pipe connected to the left side of the lower end of the quantitative tank body, and a first solenoid valve is arranged on the rubber inlet pipe body, and a rubber outlet pipe is connected to the middle of the bottom surface of the quantitative tank, and a second solenoid valve is arranged on the rubber outlet pipe body.

[0008] A further improvement is that an adjusting screw hole is provided in the middle of the bottom surface of the adjusting pressure seat.

[0009] A further improvement is that the adjusting pressure rod group includes a threaded pressure rod, and the threaded pressure rod is threadedly connected with a fixing nut for locking the threaded pressure rod after adjustment on the adjusting screw mouth, and a rotating seat is provided at the lower end of the threaded pressure rod.

[0010] A further improvement is that the sealing pressure pad is made of rubber material.

[0011] A further improvement is that the other end of the glue inlet pipe is connected to an external extruder through a glue inlet hose.

[0012] The beneficial effects of the utility model are:

[0013] The utility model provides a hot melt adhesive quantitative glue supply device, which is composed of a quantitative tank group, a supply mechanism, and a controller on a frame. The device can quantitatively supply glue in the quantitative tank by simply adjusting the screw rod. Therefore, when the supply mechanism squeezes the glue into the quantitative tank, the glue can be supplied according to the set amount, ensuring that the glue supply amount is consistent each time without too much or too little.

[0014] There is a pressure sensor on the supply mechanism, which is controlled by the controller to control the downward stroke spacing of the servo telescope, so as to prevent the servo telescope from extending too much and causing the extrusion seat and the sealing pressure pad to pressurize the bottom of the quantitative tank cavity too much, thereby damaging the quantitative tank and the quantitative tank.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1-Figure 3The utility model provides a schematic diagram of a hot melt adhesive quantitative supply device technical solution: it includes a frame 1, a quantitative tank group 2 arranged in the middle of the frame 1, and a supply mechanism 3 vertically arranged at the upper end of the frame 1, and the lower end of the supply mechanism 3 is movably sleeved in the tank body cavity of the quantitative tank group 2, and a controller 4 is arranged on the right side of the frame 1, and the quantitative tank group 2 and the supply mechanism 3 are electrically connected to the controller 4, and the supply mechanism 3 includes a servo retractor 31, a pressure sensor 32 arranged at the lower end of the servo retractor 31, an adjustment pressure seat 33 vertically arranged on the bottom surface of the pressure sensor 32, and an adjustment pressure rod group 34 threadedly connected to the lower end of the adjustment pressure seat 33, and the lower end of the adjustment pressure rod group 34 is provided with an extrusion seat 35, and the extrusion seat 35 is sleeved with a sealing pressure pad 3 6. The quantitative tank group 2 includes a quantitative tank 21, a quantitative meter 22 arranged on the front surface of the quantitative tank 21, and a rubber inlet pipe 23 connected to the left side of the lower end of the quantitative tank 21, and a first solenoid valve 24 is arranged on the rubber inlet pipe 23. A rubber outlet pipe 25 is connected to the middle of the bottom surface of the quantitative tank 21, and a second solenoid valve 26 is arranged on the rubber outlet pipe 25. An adjusting screw 331 is provided in the middle of the bottom surface of the adjusting pressure seat 33. The adjusting pressure rod group 34 includes a threaded pressure rod 341, and a fixing nut 342 is threadedly connected to the threaded pressure rod 341 for locking the threaded pressure rod 341 after adjustment on the adjusting screw 331. A rotating seat 343 is arranged at the lower end of the threaded pressure rod 341, and the sealing pressure pad 36 is made of rubber.

[0020] Working principle:

[0021] When in use, according to the amount of glue to be supplied, the threaded pressure rod 341 is twisted and adjusted to rise and fall on the adjusting screw port 331, and the height of the extrusion seat 35 and the sealing pressure pad 36 inserted into the cavity of the quantitative tank 21 is adjusted to perform quantitative supply. When adjusting, the quantitative meter 22 is viewed to confirm the quantitative supply. After the threaded pressure rod 341 is locked with the fixing nut 342, when the quantitative tank 21 is filled with glue, the glue is fed through the glue feeding pipe 23 through the external extruder. During the glue feeding process, the second solenoid valve 26 is closed. When the glue is to be supplied quantitatively, the first solenoid valve 24 is closed, and the second solenoid valve 26 is closed. 26 is opened, and at this time, it can be extended downward through the servo retractor 31, and the sealing pressure pad 36 is squeezed downward from the upper end of the quantitative tank 21 cavity through the pressure sensor 32, the adjustment pressure seat 33, the adjustment pressure seat 33, the adjustment pressure rod group 34, and the extrusion seat 35 to perform quantitative supply. When the sealing pressure pad 36 drops to the bottom of the cavity of the extrusion quantitative tank 21, the pressure sensor 32 will transmit a signal to the controller 4 after sensing the pressure setting value, and the controller 4 will issue a command to the servo retractor 31 to stop descending and rise to reset, so as to prepare for the next round of quantitative glue supply.
