[0018] 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.

[0019] Please see Figures 1-4The present invention provides a technical solution: a plaster extrusion device, including a tray 1, a base 2 disposed directly below the tray 1, and columns 3 fixedly disposed on the bottom surface of the tray 1 near the four corners. Each column 3 has a first limiting clamp 4 at its bottom end, and the bottom end of each first limiting clamp 4 is connected to the top surface of the base 2. A material carrier 5 is disposed in the middle of the top surface of the base 2. A groove 6 is opened on the top surface of the tray 1. A through hole 7 is opened in the middle of the bottom of the inner cavity of the groove 6. A material bucket 8 is disposed in the inner cavity of the groove 6. A discharge mechanism 9 is disposed on one side of the bottom surface of the tray 1. One end of the discharge mechanism 9 passes through the through hole 7 and the groove 6 and extends into the inner cavity of the material bucket 8. An installation hole 10 for installing the discharge mechanism 9 is opened in the inner cavity of the groove 6 and around the through hole 7. A pressing mechanism 14 is disposed on the top surface of the tray 1 and outside the material bucket 8. The base 2 allows for installation in a designated location and also secures the four uprights 3 mounted on the pallet 1 via four first limiting clamps 4, thereby improving the stability of the pallet 1. It also provides a foundation for the material carrier 5. The pallet 1, through the groove 6, provides a preliminary installation foundation for the material bucket 8, and through the through hole 7 and mounting hole 10, it secures the dispensing mechanism 9. It also provides an attachment and installation foundation for the pressing mechanism 14. When the plaster needs to be extruded, the operator first places the storage bottle in the designated position on the material carrier 5, allowing the material carrier 5 to position the storage bottle. Then, by activating the pressing mechanism 14 and the discharging mechanism 9, the pressing mechanism 14 can squeeze the plaster in the material barrel 8 downwards, thereby making the plaster in the material barrel 8 in a dense state. Then, the discharging mechanism 9 can continuously and evenly extrude the dense plaster downwards, and then transport the plaster to the storage bottle located on the material carrier 5, so as to improve the accuracy and efficiency of plaster extrusion. After the discharging mechanism 9 extrudes a certain amount of plaster, the pressing mechanism 14 can squeeze the plaster in the material barrel 8 downwards again, so as to ensure the quality and accuracy of subsequent plaster extrusion.

[0020] See Figures 3-5 The discharge mechanism 9 includes a stabilizing frame 91 disposed on one side of the bottom surface of the pallet 1. The stabilizing frame 91 is connected to the bottom surface of the pallet 1 by a plurality of first fixing screws 92. An extrusion head 93 is disposed in the middle of the stabilizing frame 91. The upper part of the extrusion head 93 passes through the through hole 7 and the groove 6 and extends into the inner cavity of the material barrel 8. A first servo motor 94 is disposed on one side of the bottom of the stabilizing frame 91. The output end of the first servo motor 94 is connected to the input end of the extrusion head 93. The stabilizing frame 91 in the discharge mechanism 9 can be installed in the mounting holes 10 on the tray 1 by multiple first fixing screws 92, and the extrusion head 93 and the first servo motor 94 can be installed and fixed. Since the upper part of the extrusion head 93 passes through the through hole 7 and the groove 6 and extends into the inner cavity of the material barrel 8, the precise output of the first servo motor 94 can control the precise operation of the extrusion head 93, thereby enabling the precise extrusion of the plaster in the material barrel 8.

[0021] See Figure 3 , Figure 4 Limiting seats 11 are provided on the top surface of the pallet 1 and on both sides of the groove 6. The side walls of the two limiting seats 11 are provided with first screw holes 12. The inner cavities of the two first screw holes 12 are rotatably connected with locking screws 13 for limiting the material bucket 8. The limiting seat 11 can be fixed on the tray 1 and provide space for the first screw hole 12. Then, by rotating the locking screw 13 located in the first screw hole 12, one end of the locking screw 13 can be fixed on the material bucket 8, thereby fixing the material bucket 8 installed in the groove 6 again, so as to improve the stability of the material bucket 8 in use.

[0022] See Figure 3 , Figure 4 , Figures 6-7 The pressing mechanism 14 includes a support plate 141. At least three guide holes 142 are provided on the top surface of the support plate 141 near its edge. A guide post 143 is inserted into the inner cavity of each guide hole 142. The bottom end of each guide post 143 is connected to the top surface of the support plate 1 via a second limiting clamp 144. A retainer 145 is fixedly mounted on each guide post 143, and the top end of each retainer 145 is connected to the bottom surface of the support plate 141. A pressing assembly 146 is provided on the support plate 141. A driving assembly 147 is provided above the pressing assembly 146. The top ends of multiple guide posts 143 are fixedly connected to the drive assembly 147. The output end of the drive assembly 147 is rotatably connected to the middle position of the top of the pressing assembly 146. A slot 149 is provided in the middle position of the top surface of the support plate 141. Multiple stepped holes 148 are provided around the top surface of the support plate 141 and around the slot 149. Two sensing sensors 1410 are provided on the guide post 143 located away from the pressing assembly 146. A sensing plate 1411 is provided on the top side of the pressing assembly 146 and on the side of the two sensing sensors 1410. The three guide pillars 143 in the pressing mechanism 14 can be fixed to the top surface of the tray 1 by the three second limiting clamps 144, and can also provide stable support for the drive assembly 147. They can also be inserted into the inner cavity of the three guide holes 142 on the support plate 141. Then, through the three card holders 145, they can be fixed to the three guide pillars 143 respectively, or installed on the support plate 141, thus ensuring that the support plate 141 is stably fixed to the guide pillars 143. Then, through the drive assembly 147, the pressing assembly 146 can be driven to move smoothly downwards along the guide pillars 143, so that the bottom of the pressing assembly 146 can be inserted into the inner cavity of the material tank 8, thereby squeezing the plaster in the material tank 8 downwards to ensure that the plaster in the material tank 8 is in a compacted state. The bottom of the drive assembly 147 can be limited by the slot 149, thereby ensuring the stability of the output of the drive assembly 147. The pressing assembly 146 can be installed and fixed at designated positions by multiple stepped holes 148. When the sensing plate 1411 moves to the position of the upper sensing sensor 1410, the current sensing sensor 1410 can detect the position of the sensing plate 1411. At this time, it indicates that the output of the pressing assembly 146 is in the initial state. When the sensing plate 1411 moves to the position of the lower sensing sensor 1410, the current sensing sensor 1410 can detect the position of the sensing plate 1411. At this time, it indicates that the output of the pressing assembly 146 is in the lowest state. Then, under the control of the external control, it can remind the staff to add plaster to the material bucket 8.

[0023] See Figure 3 , Figure 4 , Figures 6-8 The pressing component 146 includes a lifting plate 1461. An internal threaded seat 1462 is installed through the middle of the top surface of the lifting plate 1461. The inner cavity of the internal threaded seat 1462 is rotatably connected to the output end of the drive component 147. First guide seats 1463 are installed through both sides of the top surface of the lifting plate 1461. Guide posts 143 penetrate the inner cavity of the first guide seats 1463. A pressing plate 1465 is provided directly below the lifting plate 1461. Multiple pressing posts 1464 are arranged around the top surface of the pressing plate 1465 and near the edge. The top of each pressing post 1464 is connected to the lifting plate 1461. A second guide seat 1466 is fixedly installed through the inner cavity of each stepped hole 148. The pressing post 1464 penetrates the inner cavity of the second guide seat 1466. The lifting plate 1461 in the pressing assembly 146 can be rotatably connected to the output end of the drive assembly 147 via the internal thread seat 1462, and can also be movably connected to the two guide posts 143 via the two first guide seats 1463, thereby guiding the lifting plate 1461 to move smoothly up and down along the guide posts 143. The three second guide seats 1466 can be fixed to the three stepped holes 148 on the support plate 141, and can also be movably connected to the three pressing posts 1464 installed on the support plate 141. Because the three pressing posts 1464... The bottom end of 64 is equipped with a lower pressure plate 1465. So when the drive assembly 147 is running, it can drive the lifting plate 1461 to move downward along the guide column 143 via the internal thread seat 1462. At the same time as the lifting plate 1461 moves downward, it can also move downward along the second guide seat 1466 via the lower pressure column 1464, so as to synchronously drive the lower pressure plate 1465 to move downward in the material barrel 8, thereby squeezing the plaster in the material barrel 8 downward, so that the plaster in the material barrel 8 is in a dense state.

[0024] See Figure 3 , Figure 7 and Figure 8 The outer wall of the lower pressure plate 1465 is provided with an annular groove 1467, and the inner cavity of the annular groove 1467 is provided with a sealing ring 1468. The top-view outer diameter of the lower pressure plate 1465 is the same as the top-view inner diameter of the material barrel 8, which can improve the sealing effect between the periphery of the lower pressure plate 1465 and the inner wall of the material barrel 8.

[0025] See Figures 6-9 The drive assembly 147 includes a stabilizing plate 1471. The top of each guide post 143 is fixedly connected to the stabilizing plate 1471. A second servo motor 1472 is provided on the top of the stabilizing plate 1471, and the output end of the second servo motor 1472 passes through the middle of the bottom surface of the stabilizing plate 1471. The output end of the second servo motor 1472 and located below the stabilizing plate 1471 are connected to a drive screw 1473 via a coupling. The drive screw 1473 passes through an internal thread seat 1462, and the two are rotatably connected. The stabilizing plate 1471 in the drive assembly 147 can be fixedly connected to the top of the three guide posts 143 and can also be used to install the second servo motor 1472. The second servo motor 1472 can drive the drive screw 1473 to rotate via the coupling, thereby enabling the rotating drive screw 1473 to synchronously drive the internal thread seat 1462 to move up and down along the drive screw 1473. This allows the position and height of the lifting plate 1461 to be adjusted so that the pressure plate 1465 can be positioned inside the material bucket 8.

[0026] See Figure 6 , Figure 9The inner cavity of the slot 149 is provided with a first bearing 1474 for supporting the drive screw 1473. The first bearing 1474 can not only fix the inner cavity of the slot 149 on the support plate 141, but also provide limiting support for the bottom end of the drive screw 1473, thereby improving the stability of the drive screw 1473 when rotating.

[0027] See Figure 9 A second bearing 1475 is provided on the drive screw 1473 near the top end. A limit frame 1476 is provided on the outside of the second bearing 1475, and the limit frame 1476 is fixedly connected to the stabilizing plate 1471 by a second fixing screw 1477. The limiting bracket 1476 can be fixed to the stabilizing plate 1471 by the second fixing screw 1477, and can also provide limiting support for the drive screw 1473 by the second bearing 1475, thereby improving the stability of the drive screw 1473 when rotating.

[0028] During operation, the base 2 can be installed in a designated position and the four columns 3 mounted on the pallet 1 can be fixed by the four first limit clamps 4, thereby improving the stability of the pallet 1. It also provides a foundation for the material carrier 5. The pallet 1 then provides a preliminary installation foundation for the material bucket 8 via the groove 6, and fixes the dispensing mechanism 9 via the through hole 7 and mounting hole 10. It also provides an attachment installation foundation for the pressing mechanism 14. When the plaster needs to be extruded, the operator first places the storage bottle in the designated position on the material carrier 5, allowing the material carrier 5 to hold the storage bottle in place. Then, by activating the pressing mechanism 14 and the discharging mechanism 9, the pressing mechanism 14 can squeeze the plaster in the material barrel 8 downwards, thereby making the plaster in the material barrel 8 in a dense state. Then, the discharging mechanism 9 can continuously and evenly extrude the dense plaster downwards, and then transport the plaster to the storage bottle located on the material carrier 5, so as to improve the accuracy and efficiency of plaster extrusion. After the discharging mechanism 9 extrudes a certain amount of plaster, the pressing mechanism 14 can squeeze the plaster in the material barrel 8 downwards again, so as to ensure the quality and accuracy of subsequent plaster extrusion.

[0029] The stabilizing frame 91 in the discharge mechanism 9 can be installed in the mounting holes 10 on the tray 1 by multiple first fixing screws 92, and the extrusion head 93 and the first servo motor 94 can be installed and fixed. Since the upper part of the extrusion head 93 passes through the through hole 7 and the groove 6 and extends into the inner cavity of the material barrel 8, the precise output of the first servo motor 94 can control the precise operation of the extrusion head 93, thereby enabling the precise extrusion of the plaster in the material barrel 8.

[0030] The limiting seat 11 can be fixed on the tray 1 and provide space for the first screw hole 12. Then, by rotating the locking screw 13 located in the first screw hole 12, one end of the locking screw 13 can be fixed on the material bucket 8, thereby fixing the material bucket 8 installed in the groove 6 again, so as to improve the stability of the material bucket 8 in use.

[0031] The three guide pillars 143 in the pressing mechanism 14 can be fixed to the top surface of the tray 1 by the three second limiting clamps 144, and can also provide stable support for the drive assembly 147. They can also be inserted into the inner cavity of the three guide holes 142 on the support plate 141. Then, through the three card holders 145, they can be fixed to the three guide pillars 143 respectively, or installed on the support plate 141, thus ensuring that the support plate 141 is stably fixed to the guide pillars 143. Then, through the drive assembly 147, the pressing assembly 146 can be driven to move smoothly downwards along the guide pillars 143, so that the bottom of the pressing assembly 146 can be inserted into the inner cavity of the material tank 8, thereby squeezing the plaster in the material tank 8 downwards to ensure that the plaster in the material tank 8 is in a compacted state. The bottom of the drive assembly 147 can be limited by the slot 149, thereby ensuring the stability of the output of the drive assembly 147. The pressing assembly 146 can be installed and fixed at designated positions by multiple stepped holes 148. When the sensing plate 1411 moves to the position of the upper sensing sensor 1410, the current sensing sensor 1410 can detect the position of the sensing plate 1411. At this time, it indicates that the output of the pressing assembly 146 is in the initial state. When the sensing plate 1411 moves to the position of the lower sensing sensor 1410, the current sensing sensor 1410 can detect the position of the sensing plate 1411. At this time, it indicates that the output of the pressing assembly 146 is in the lowest state. Then, under the control of the external control, it can remind the staff to add plaster to the material bucket 8.

[0032] The lifting plate 1461 in the pressing assembly 146 can be rotatably connected to the output end of the drive assembly 147 via the internal thread seat 1462, and can also be movably connected to the two guide posts 143 via the two first guide seats 1463, thereby guiding the lifting plate 1461 to move smoothly up and down along the guide posts 143. The three second guide seats 1466 can be fixed to the three stepped holes 148 on the support plate 141, and can also be movably connected to the three pressing posts 1464 installed on the support plate 141. Because the three pressing posts 1464... The bottom end of 64 is equipped with a lower pressure plate 1465. So when the drive assembly 147 is running, it can drive the lifting plate 1461 to move downward along the guide column 143 via the internal thread seat 1462. At the same time as the lifting plate 1461 moves downward, it can also move downward along the second guide seat 1466 via the lower pressure column 1464, so as to synchronously drive the lower pressure plate 1465 to move downward in the material barrel 8, thereby squeezing the plaster in the material barrel 8 downward, so that the plaster in the material barrel 8 is in a dense state.

[0033] The stabilizing plate 1471 in the drive assembly 147 can be fixedly connected to the top of the three guide posts 143, and the second servo motor 1472 can be installed. The second servo motor 1472 can then drive the drive screw 1473 to rotate via a coupling. This allows the rotating drive screw 1473 to synchronously drive the internal thread seat 1462 to move up and down along the drive screw 1473, thereby adjusting the position and height of the lifting plate 1461 to facilitate the lowering of the pressure plate 1465. The first bearing 1474, located inside the material hopper 8, can be fixed to the inner cavity of the slot 149 on the support plate 141 and can also provide limiting support for the bottom end of the drive screw 1473, thereby improving the stability of the drive screw 1473 when rotating. The second bearing 1476, located inside the material hopper 8, can be fixed to the stabilizing plate 1471 by the second fixing screw 1477 and can also provide limiting support for the drive screw 1473 by the second bearing 1475, thereby improving the stability of the drive screw 1473 when rotating.

[0034] In summary, the device can compress the plaster in the material barrel 8 downwards through the pressing mechanism 14, thereby making the plaster in the material barrel 8 in a dense state. Then, through the discharge mechanism 9, the dense plaster can be continuously and evenly extruded downwards, and then the plaster is transported to the storage bottle located on the material carrier 5, so as to improve the accuracy and efficiency of plaster extrusion.

[0035] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
