For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0044] Please refer to Figure 1 and Figure 2 , which shows a high-viscosity fluid extruder provided by the present invention, including a feeding assembly 1, a flipping assembly 2 for flipping the feeding assembly 1, an electric control assembly 3 and a casing assembly 4.

[0045] Please refer to Figure 3, the above-mentioned feeding assembly 1 includes a glue pushing mechanism, a glue bucket bracket 11, a glue bucket 12, a pressing plate glue discharging assembly, a pressing plate support seat 13, an exhaust pressure relief power assembly, a first bottom plate 14 and a reinforcing plate 15. The glue bucket 12 is placed on the glue bucket bracket 11, and the pressing plate glue discharging assembly is fixed on the pressing plate support seat 13; the power output end of the exhaust pressure relief power assembly is in transmission connection with the pressing plate glue discharging assembly. When the exhaust pressure relief power assembly works, it can push the pressing plate glue discharging assembly to connect the internal space of the glue bucket 12 with the outside through the pressing plate glue discharging assembly, so as to realize the exhaust or pressure relief of the glue bucket.

[0046] The reinforcing plates 15 are vertically arranged on both sides of the first bottom plate 14. The feeding assembly 1 is fixed on the first bottom plate 14, and both sides of the pressing plate support seat 13 are fixedly connected to the reinforcing plates 15 on both sides of the first bottom plate 14 respectively.

[0047] Specifically, please refer to Figure 4 , the glue pushing mechanism of this embodiment includes a motor 161, a speed reducer 162, a ball screw 163, a screw rod connecting plate 164, a moving block 165, a linear guide rail 166, a slider 167, a synchronous pulley set 168, a first bearing seat 169, a bearing support seat 16a, a photoelectric inductor 16b and a buffer column 16c.

[0048] The power output shaft of the motor 161 is coaxially connected to the speed reducer 162. The speed reducer 162 and the ball screw 163 are in transmission connection through the synchronous pulley set 168, and the ball screw 163 is in transmission connection with the screw rod connecting plate 164. The moving block 165 is fixedly connected to the screw rod connecting plate 164. The slider 167 is slidably installed on the linear guide rail 166, and the bottom of the moving block 165 is fixedly connected to the slider 167; the top of the moving block 165 is fixedly connected to the glue bucket bracket 11. Bearings are embedded in both the first bearing seat 169 and the bearing support seat 16a, and both ends of the ball screw 163 are respectively inserted into the bearings of the first bearing seat 169 and the bearing support seat 16a.

[0049] When the motor 161 rotates, it can drive the glue bucket bracket 11 and the glue bucket 12 thereon to move linearly. When the glue bucket 12 moves to the position where it abuts against the pressing plate glue discharging assembly, the glue bucket 12 is extruded to discharge glue.

[0050] To limit the movement range of the glue bucket 12 and prevent excessive extrusion and damage between components, this embodiment sets up a double protection measure. The first measure is to set up a photoelectric sensor 16b on the outer side of the linear guide 166. A baffle 16d is fixed on the slider 167. When the slider 167 moves to the position aligned with the photoelectric sensor 16b, the baffle 16d blocks the signal of the photoelectric sensor 16b, and the photoelectric sensor 16b feeds the signal back to the motor 161, and the motor 161 stops working or switches the rotation direction. The second measure is to install a buffer column 16c on the side of the bearing support column 16a facing the moving block 165, so as to play a buffering role and avoid hard contact and damage to components.

[0051] Specifically, please refer to Figure 5 The above-mentioned glue outlet assembly of the pressing disc includes a glue outlet mechanism, a second bearing seat 171, a transmission plate 172, a connecting pin 173, a high-pressure rotary joint 174, a glue outlet connector 175, and a pressure gauge 176 for monitoring the glue outlet pressure. Among them, please refer to Figure 6 and Figure 7 The glue outlet mechanism includes a glue outlet inner tube 177, a glue outlet outer tube 178, a glue pressing disc 179, and a sealing ring 17a.

[0052] The glue outlet inner tube 177 is embedded in the glue outlet outer tube 178. The interior of the glue outlet inner tube 177 has a glue outlet channel 1771 running through its axial direction; the glue pressing disc 179 is embedded in the glue bucket 12, and the glue pressing disc 179 is connected to one end of the glue outlet outer tube 178 close to the glue bucket 12. The glue outlet inner tube 177 has a main body section and a tapered end 1772. Among them, the tapered end 1772 is located at one end of the main body section close to the glue pressing disc 179; a ventilation groove 1773 running through the main body section is provided on the outer peripheral edge of the glue outlet inner tube 177; a tapered inner cavity 1791 matching the shape of the tapered end 1772 is provided inside the glue pressing disc 179, and the tapered end 1772 is embedded in the tapered inner cavity 1791; one end of the glue outlet inner tube 177 away from the glue pressing disc 179 is a power connection part; the sealing ring 17a is sleeved on the outer peripheral edge of the glue pressing disc 179.

[0053] A bearing is embedded in the second bearing seat 171. The power connection part of the glue outlet inner tube 177 penetrates into the bearing of the second bearing seat 171 and is clamped with the transmission plate 172 through a snap ring 17b; the transmission plate 172 is connected to the power output end of the exhaust and pressure relief power assembly through a connecting pin 173; one end of the high-pressure rotary joint 174 is rotatably docked with the glue outlet of the glue outlet inner tube 177, and the glue outlet connector 175 is docked with the other end of the high-pressure rotary joint 174. The sensing device of the pressure gauge 176 is inserted inside the glue outlet connector 175. Setting the second bearing seat 171 can realize the rotation of the glue bucket 12 and prevent glue precipitation and glue liquid separation.

[0054] Please refer to Figure 8, the above exhaust pressure relief power assembly includes a cylinder 181, a flexible connecting plate 182, and a guide post 183. The guide post 183 passes through the flexible connecting plate 182, and the flexible connecting plate 182 is connected to the piston rod of the cylinder 181. A hole groove 1821 is provided at the top of the flexible connecting plate 182, and the bottom end of the connecting pin 173 is inserted into the hole groove 1821, thereby realizing the floating connection between the exhaust pressure relief power assembly and the pressure plate glue discharging assembly. By providing the guide post 183, the smooth sliding of the flexible connecting plate 182 can be assisted.

[0055] When the cylinder 181 works, it can push / pull the pressure plate glue discharging assembly to move forward or backward. When replacing the glue, the glue inner tube 177 is pushed inward. The ventilation groove 1773 between the glue inner tube 177 and the glue outer tube 178 is communicated with the inside of the glue bucket 12, and the air inside the glue bucket 12 automatically discharges outward through the ventilation groove 1773. This prevents the glue from contacting the air remaining inside the glue bucket 12 and reduces the waste of glue when exhausting air. When replacing the glue bucket 12 after the glue is squeezed out, the external air can enter the glue bucket 12 through the ventilation groove 1773 to relieve pressure and break the vacuum, facilitating the removal of the glue bucket 12 without manually opening the exhaust valve or injecting compressed air, thus improving work efficiency.

[0056] Please refer to Figure 9 , when the glue inner tube 177 is pushed outward, the sealing ring 17c of the glue inner tube 177 is completely squeezed and fitted with the tapered inner cavity 1791 of the glue pressing plate 179 to achieve air isolation, and the glue can flow out through the glue discharging channel 1771.

[0057] Please refer to Figures 10 to 12 , the above flipping assembly 2 includes a flipping rod 21, a flipping handle 22, a flipping seat 23, a support column 24, a second bottom plate 25, a vertical buffer 26, a buffer support 27, and a horizontal buffer 28.

[0058] One end of the flipping handle 22 is fixedly connected to one end of the flipping rod 21. The flipping rod 21 is rotatably installed on the support column 24. The bottom end of the flipping seat 23 is fixedly connected to the flipping rod 21, and its top end is fixedly connected to the first bottom plate 14 of the feeding assembly 1. When the user operates the flipping handle 22, the first bottom plate 14 and the feeding assembly 1 thereon can rotate around the flipping rod 21, thereby realizing the state switching of the feeding assembly 1.

[0059] The vertical buffer 26 is installed on the top of the buffer support 27. The buffer support 27, the horizontal buffer 28, and the support column 24 are all fixed on the second bottom plate 25; when the feeding assembly 1 is in the horizontal placement state (as Figure 10 shown), the vertical buffer 26 abuts against the first bottom plate 14 upward. When the feeding assembly 1 is in the vertical placement state (as Figure 12As shown, the horizontal buffer 28 abuts against the first bottom plate 14. Through the above buffer measures in this embodiment, collisions between components can be prevented, and the horizontal and vertical states of the feeding assembly 1 can be limited respectively.

[0060] The electric control assembly 3 includes electric control devices 31 and an electric shield 32. The electric control devices 31 include a driver, a power supply, and a PLC controller, and the electric shield 32 covers the electric control devices 31.

[0061] Please refer to Figure 13 , the housing assembly 4 includes a sheet metal housing 41, control buttons 42, signal indicator lights 43, a weighing mechanism 44, and a human-machine touch controller 45.

[0062] A sheet metal door 46 connected by a hinge is provided on the sheet metal housing 41. When the sheet metal door 46 is opened, the user is exactly facing the position of the glue bucket 12, which is convenient for replacing the fluid material. A side seal plate 47 for convenient maintenance, inspection, and daily maintenance is provided on the side of the sheet metal housing 41. The control buttons 42 are used for the user to implement control operations, the weighing mechanism 44 is used for closed-loop control of the fluid discharge accuracy, and the human-machine touch controller 45 is used for the user to set device parameters and control the air pressure of the pressure gauge 176.

[0063] In summary, for the high-viscosity fluid extruder in this embodiment, the pressure plate glue discharging assembly is driven by the exhaust pressure relief power assembly, which can automatically discharge the air in the glue bucket 12 after the glue is added to the glue bucket 12. At the same time, after the glue is extruded, the inside of the glue bucket 12 can be communicated with the outside world to automatically relieve pressure, so as to pull out the glue bucket 12. The glue pushing structure uses the motor 161 and the ball screw 163 as the power medium, with low running noise, high precision, and stable performance.

[0064] In addition, by operating the flipping assembly 2, the switching between the horizontal state and the vertical state of the feeding assembly 1 can be realized. When it is necessary to replace the fluid slurry, the feeding assembly 1 can be flipped to the vertical state. At this time, the feeding assembly 1 is located on the side of the extruder, which is convenient for the user to perform the replacement operation.
