[0021] Beneficial effects:

[0022] The high-viscosity fluid dispensing machine of this application has a simple structure and good rigidity. By designing the center lines of the support, main cylinder, pneumatic pump, pressure plate cylinder, and pressure plate as coaxial, it solves the problem that the high-viscosity fluid in the dispensing machine is prone to being evacuated in the middle due to its low flow rate, which leads to the suction mechanism sucking up air.

[0023] At the same time, the main cylinder is connected to the pneumatic pump, the pneumatic pump is connected to the pressure plate cylinder, and the pressure plate cylinder is connected to the pressure plate, so that the entire pressure force is transmitted downward along the central axis, making the force transmission more reasonable and avoiding the mutual influence of the forces of the two cylinders.

[0024] The design of the pressure plate and its cylinder serves two main purposes: firstly, it moves the pressure plate away from the pneumatic pump's inlet when it enters the barrel, facilitating feeding; secondly, when the pneumatic pump's inlet reaches the bottom of the barrel, the pressure plate continues to press down, reducing residual liquid at the bottom. The spherical pressure head design allows the cylinder to oscillate slightly during operation, improving the system's flexibility and making it suitable for barrels with some tilt, including tilted and off-center conditions. The trolley design allows the entire device to move freely using four directional wheels and two steering wheels. This trolley features a high load capacity and low center of gravity, and its load capacity can be further increased by widening and increasing the number of wheels. Attached Figure Description

[0041] The present invention will now be described in further detail with reference to the accompanying drawings.

[0042] like Figure 1 As shown:

[0043] A high-viscosity fluid dispensing machine, comprising:

[0044] The bracket 10 consists of two side bracket plates 11 and a connecting plate connecting the side bracket plates 11, with the two side bracket plates 11 arranged opposite to each other;

[0045] A first lifting mechanism 20 is disposed on the bracket 10. The first lifting mechanism 20 includes a first lifting rod that can move in the up and down direction and a first driving mechanism for driving the first lifting rod to move.

[0046] The first drive mechanism is the main cylinder body 21, and the first lifting rod is the first telescopic piston rod 22 that cooperates with the main cylinder body 21.

[0047] It should be noted that the first driving mechanism is the main cylinder body 21, and the first lifting rod is the first telescopic piston rod 22 that cooperates with the main cylinder body 21. This is only one embodiment. Other embodiments include, but are not limited to, the first driving mechanism being the first motor and the first lifting rod being the first threaded rod that cooperates with the first motor.

[0048] A pneumatic pump 30 is installed at the end of the first lifting rod and moves up and down with the first lifting rod;

[0049] The second lifting mechanism 40 is disposed on the pneumatic pump 30. The second lifting mechanism 40 includes a second lifting rod that can move in the up and down direction and a second driving mechanism for driving the second lifting rod to move.

[0050] The second driving mechanism consists of a first pressure plate cylinder body 411 and a second pressure plate cylinder body 421 symmetrically arranged with respect to the center line of the pneumatic pump 30. The second lifting rod consists of a second telescopic piston rod 412 and a third telescopic piston rod 422 that cooperate with the first pressure plate cylinder body 411 and the second pressure plate cylinder body 421, respectively.

[0051] The first pressure plate cylinder body 411 is mounted on the pressure plate 31, the end of the second telescopic piston rod 412 is fixedly connected to the pressure plate 50, the second pressure plate cylinder body 421 is mounted on the pressure plate 31, and the end of the third telescopic piston rod 422 is fixedly connected to the pressure plate 50.

[0052] It should be noted that the second drive mechanism is a first pressure plate cylinder body 411 and a second pressure plate cylinder body 421 symmetrically arranged with respect to the center line of the pneumatic pump 30, and the second lifting rod is a second telescopic piston rod 412 and a third telescopic piston rod 422 that cooperate with the first pressure plate cylinder body 411 and the second pressure plate cylinder body 421 respectively. This is only one embodiment, and other embodiments include, but are not limited to, the second drive mechanism being a second motor and a third motor symmetrically arranged with respect to the center line of the pneumatic pump, and the second lifting rod being a second threaded rod and a third threaded rod that cooperate with the second motor and the third motor respectively.

[0053] A pressure plate 50 is disposed at the end of the second lifting rod;

[0054] The shape of the pressure plate 50 is adapted to the inner wall of the material barrel 70. The pressure plate 50 has an inner hole and is sleeved on the feed part of the pneumatic pump 30. The inner diameter of the inner hole is adapted to the outer diameter of the feed part. When the second telescopic piston rod 412 and the third telescopic piston rod 422 are in the retracted state, the pressure plate 50 is positioned higher than the feed inlet at the bottom of the pneumatic pump 30. When the second telescopic piston rod 412 and the third telescopic piston rod 422 are in the extended state, the pressure plate 50 is positioned lower than the feed inlet at the bottom of the pneumatic pump 30.

[0055] This design connects the main cylinder to the pneumatic pump, the pneumatic pump to the pressure plate cylinder, and the pressure plate cylinder to the pressure plate. The entire pressing force is transmitted downward along the central axis, making the force transmission more reasonable and avoiding the mutual influence of the forces between the two pressure plate cylinders.

[0056] In addition, when the pressure plate just enters the barrel, the second and third telescopic piston rods are in a retracted state, which moves the pressure plate away from the pneumatic pump inlet, which is conducive to feeding. When the pneumatic pump inlet reaches the bottom of the barrel, the second and third telescopic piston rods are in an extended state, which makes the pressure plate continue to press down, which helps to reduce the residual liquid at the bottom of the barrel.

[0057] like Figure 3 As shown: The side support plate 11 includes a base 111, a side portion 112 formed by bending and extending from one end of the base 111, and a mounting portion 113 connected to the upper end of the side portion 112. The base 111, side portion 112, and mounting portion 113 are all plate-shaped structures. A mounting plate 12 is provided between the mounting portions 113 of the two side support plates 11, and the first lifting mechanism 20 is installed at the center position of the mounting plate 12. The side support plate has a simple structure and good rigidity. This design ensures that the center line of the support, the center line of the main cylinder, the center lines of the two pressure cylinders, the center line of the pneumatic pump, and the center line of the pressure plate are in a coaxial position, making the force transmission more reasonable when the entire device is operating.

[0058] like Figure 2 As shown, the first telescopic piston rod 22 is connected to the pneumatic pump 30 via a spherical pressure head assembly 60. The spherical pressure head assembly 60 includes an integrally formed spherical pressure head 61 and a spherical pressure head support plate 62. The first telescopic piston rod 22 is fixedly connected to the spherical pressure head 61. The spherical pressure head support plate 62 is connected to the pressure plate 31 at the top of the pneumatic pump 30 via a pull rod. The pull rod 63 passes through the spherical pressure head support plate 62, and the end of the pull rod 63 is fixedly connected to the pressure plate 31. There are four pull rods 63.

[0059] The first telescopic piston rod 22 is threadedly connected to the spherical pressure head 61 and is fastened by the first tightening nut 64. The pull rod 63 passes through the spherical pressure head bearing plate 62, and the end of the pull rod 63 is threadedly connected to the pressure plate 31 and is fastened by the second tightening nut 65.

[0060] The spherical pressure head design allows the cylinder to have a certain degree of sway during operation, which is beneficial for the flexible centering of the entire system and makes it suitable for working conditions where the material bucket is tilted to a certain extent, including working conditions where the material bucket is tilted or deviated from the center.

[0061] like Figure 1 and 3 As shown, the bracket 10 is mounted on the trolley, which includes a flat trolley body 81, wheels at the bottom of the flat trolley body 81, and a push handle 82 at one end of the flat trolley body 81. The wheels include four directional wheels 84 at one end of the flat trolley body 81 and two omnidirectional wheels 83 at the other end of the flat trolley body 81.

[0062] This design allows the entire device to move freely using four directional wheels and two steering wheels. The cart is designed to have a high load capacity and a low center of gravity, and the load capacity can be increased by widening the wheels and increasing the number of wheels.

[0063] like Figure 4 As shown,

[0064] A control system for a high-viscosity fluid dispensing machine includes a main cylinder 20, a first pressure plate cylinder 41, a second pressure plate cylinder 42, a pneumatic pump 30, a metering gun 91, and an air supply unit 92 with a pressure source. The air supply unit 92 provides compressed air to the main cylinder 20, the first pressure plate cylinder 41, the second pressure plate cylinder 42, and the pneumatic pump 30. The pneumatic pump 30 includes a first air inlet, a first feed inlet, and a first discharge outlet. The first air inlet is connected to the... An air supply unit 92 with a pressure source is connected, the first feeding unit is disposed in the material barrel 70, the first discharging unit is connected to the metering gun 91, a first valve 93 is provided between the main cylinder 20 and the air supply unit 92 with a pressure source, a second valve 94 and a third valve 95 are provided between the first pressing plate cylinder 41, the second pressing plate cylinder 42 and the main cylinder 20, and the second valve 94 and the third valve 95 are used to control the first pressing plate cylinder 41 and the second pressing plate cylinder 42;

[0065] Wherein, a pressure boosting valve 96 is provided between the first valve 93 and the air supply unit 92 with a pressure source; a pressure reducing valve 97 is provided between the second valve 94 and the third valve 95 and the air supply unit 92 with a pressure source; a pressure reducing valve 98 is provided between the pneumatic pump 30 and the air supply unit 92 with a pressure source; a first throttle valve 1001 is provided between the first valve 93 and the material barrel 70; a second throttle valve 1002 is provided between the first valve 93 and the main cylinder 20; a third throttle valve 1003 is provided between the second valve 94 and the third valve 95 and the pressure reducing valve 97; a fourth throttle valve 1004 is provided between the pneumatic pump 30 and the pressure reducing valve 98; and an exhaust pipe is provided on the pressure plate 50, with a fifth throttle valve 1005 provided on the exhaust pipe.

[0066] Preferably, the first valve 93 is a three-position five-way manual valve, the second valve 94 is a first pneumatic limit switch, the third valve 95 is a second pneumatic limit switch, the main cylinder 20 includes a main cylinder body 21 and a first telescopic piston rod 22 extending through the axial end of the main cylinder body 21, the first pressure plate cylinder 41 includes a first pressure plate cylinder body 411 and a second telescopic piston rod 412 extending through the axial end of the first pressure plate cylinder body 411, and the second pressure plate cylinder 42 includes a second pressure plate cylinder body 421 and a second pressure plate cylinder... The third telescopic piston rod 422 is located at the axial end of the main body 421. The first telescopic piston rod 22 is equipped with a limit switch block. When the first telescopic piston rod 22 is in the extended state, the limit switch block triggers the first pneumatic limit switch, and the first pressure plate cylinder body 411 drives the second telescopic piston rod 412 to move downward. At the same time, the second pressure plate cylinder body 421 drives the third telescopic piston rod 422 to move downward. When the first telescopic piston rod 22 is in the retracted state, the limit switch block triggers the second pneumatic limit switch, and the first pressure plate cylinder body 411 drives the second telescopic piston rod 412 to move upward. At the same time, the second pressure plate cylinder body 421 drives the third telescopic piston rod 422 to move upward.

[0067] Work process:

[0068] like Figure 5 and 6 As shown:

[0069] The filling machine is in state one: the pistons of the main cylinder and the pressure plate cylinder are at their highest positions, and the pneumatic pump and the pressure plate are at their highest positions.

[0070] like Figure 7 and 8 As shown:

[0071] The dispensing machine is in state two: Manually operate the first valve, open the second throttle valve and the fifth throttle valve, the piston of the main cylinder moves downward, the first telescopic piston rod carries the spherical pressure head assembly, pneumatic pump, pressure plate cylinder and pressure plate downward. The suction end of the pneumatic pump enters below the liquid surface first, and moves down to the pressure plate press against the surface of the high-viscosity liquid. The fifth throttle valve is closed, the spherical pressure head continues to move downward, transmitting pressure to the pressure plate, and then to the pneumatic pump and pressure plate cylinder. Finally, the pressure is transmitted to the pressure plate, the main cylinder pushes the pressure plate downward, and at the same time opens the fourth throttle valve, the pneumatic pump starts to lift the material.

[0072] like Figure 9 and 10 As shown:

[0073] The filling machine is in state three: the pneumatic pump lifts the material, and at the same time the main cylinder pushes the pneumatic pump and the pressure plate down to the lower limit position of the main cylinder. The suction end of the pneumatic pump is close to the bottom of the material barrel, and the main cylinder stops operating.

[0074] like Figure 11 and 12 As shown:

[0075] When the filling machine is in state four: the pneumatic pump is lifting material, the limit switch block of the first telescopic piston rod moves down and triggers the first pneumatic limit switch, the pressure plate cylinder moves, the cylinder piston rod pushes the pressure plate to continue to move down, forcing the liquid to continue to enter the pneumatic pump, the pressure plate cylinder moves down to its lower limit position, and at the same time the pressure plate moves down to near the bottom of the material tank, so as to minimize the residual liquid.

[0076] like Figure 13 and 14 As shown:

[0077] When the filling machine is in state five: the second throttle valve is closed and the first throttle valve is opened, compressed air is filled into the material barrel, pushing the pressure plate upward. At the same time, the first valve 93 is manually operated, causing the main cylinder to pull the lever. The lever pulls the pressure plate, pneumatic pump, pressure plate cylinder, and pressure plate upward. When the pressure plate rises to near the opening of the material barrel, the first throttle valve is closed. When the main cylinder rises to its limit position, the main cylinder stops moving.

[0078] like Figure 15 and 16 As shown:

[0079] When the filling machine is in state six: the limit switch block of the first telescopic piston rod moves up and triggers the second pneumatic limit switch, the pressure plate cylinder moves, the cylinder piston rod pulls the pressure plate to continue moving up, the pressure plate cylinder stops moving, the initial state is restored, and the material bucket is replaced.

[0080] In summary, the high-viscosity fluid dispensing machine of this application embodiment has a simple structure and good rigidity. By designing the center lines of the support, main cylinder, pneumatic pump, pressure plate cylinder, and pressure plate as coaxial, it solves the problem that the low flow rate of high-viscosity fluid in the dispensing machine easily causes the middle part to be evacuated, resulting in the suction mechanism sucking up air.

[0081] At the same time, the main cylinder is connected to the pneumatic pump, the pneumatic pump is connected to the pressure plate cylinder, and the pressure plate cylinder is connected to the pressure plate, so that the entire pressure force is transmitted downward along the central axis, making the force transmission more reasonable and avoiding the mutual influence of the forces of the two cylinders.

[0082] The design of the pressure plate and its cylinder serves two main purposes: firstly, it moves the pressure plate away from the pneumatic pump's inlet when it enters the barrel, facilitating feeding; secondly, when the pneumatic pump's inlet reaches the bottom of the barrel, the pressure plate continues to press down, reducing residual liquid at the bottom. The spherical pressure head design allows the cylinder to oscillate slightly during operation, improving the system's flexibility and making it suitable for barrels with some tilt, including tilted and off-center conditions. The trolley design allows the entire device to move freely using four directional wheels and two steering wheels. This trolley features a high load capacity and low center of gravity, and its load capacity can be further increased by widening and increasing the number of wheels.

[0083] The above are merely preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several similar modifications and improvements can be made without departing from the inventive concept of the present invention, and these should also be considered within the scope of protection of the present invention.
