Description

Technical Field

[0001] This utility model relates to the technical field of gypsum filling equipment, specifically to a gypsum mixing, filling, and vacuuming machine. Background Technology

[0002] Precious metals are highly sought after due to their unique luster and value retention. Taking gold as an example, the vast majority of gold jewelry is made using the lost-wax casting technique. Lost-wax casting typically uses a plaster cavity as the casting container. The general process includes making a wax tree model, fixing the wax tree model with plaster, high-temperature loss of wax and plaster solidification to form a plaster cavity model, and then pouring molten metal into the plaster cavity model to complete the casting process.

[0003] In the prior art, there is a patent document with publication number CN205951030U entitled "A Vacuum Plaster Mixing Machine for Preparing Plaster Mold Cavities in Lost Wax Casting." This document describes a method that improves the density of the plaster cavity by mixing the plaster, followed by a vacuuming device and a vibration motor, thereby reducing porosity and increasing the yield. However, during operation, the plaster, due to its high viscosity, adheres to the inner wall of the cavity during the descent and vacuuming process. If not flushed promptly, the plaster will harden and solidify, making subsequent cleaning more difficult and affecting continuous operation. Furthermore, because the same material cylinder is used for both mixing and cleaning, impurities after cleaning cannot be discharged in a timely manner, affecting the production of subsequent products. Utility Model Content

[0004] To overcome the above-mentioned defects, the purpose of this utility model is to provide a gypsum mixing, filling and vacuuming machine, which enables separate and rapid cleaning of the sealing cap, ensuring product quality and improving the product qualification rate.

[0005] To achieve the above objectives, this utility model provides a gypsum mixing, filling, and vacuuming machine, comprising: a base, on which a mixing device and a vacuuming device are provided; the mixing device includes a material cylinder and a stirring motor, the material cylinder having a sieve plate and a stirring shaft inside; the stirring shaft penetrating the sieve plate, and the bottom of the stirring shaft being driven and connected to the stirring motor via a pulley mechanism, the stirring shaft having a plurality of stirring blades fixedly mounted on it; the vacuuming device includes a material collecting cylinder, a sealing cover being provided between the material cylinder and the material collecting cylinder, the sealing cover having a discharge valve connecting the material cylinder and the material collecting cylinder, the material collecting cylinder being connected to a vacuum pump; a vibration motor being installed at the bottom of the material collecting cylinder; a rotating mechanism being provided on the base, the rotating mechanism including a connecting seat and a support column, the connecting seat being sleeved on the support column, the material cylinder and the stirring motor being fixedly mounted on the connecting seat; along the rotational circumference of the connecting seat, the base also has a cleaning basin corresponding to the sealing cover, the cleaning basin having a cleaning nozzle inside.

[0006] Preferably, the cylinder cover lifting device includes a lifting rod and a traction rope. One end of the lifting rod is provided with a guide block, one end of the traction rope is fixedly connected to the cylinder cover of the material cylinder, and the other end of the traction rope is connected to a winding device.

[0007] Preferably, the height of the boom is greater than the height of the support column.

[0008] Preferably, the cylinder cover lifting device is further provided with an angle adjusting motor, and the motor shaft of the angle adjusting motor is connected to the connecting seat in a driving connection.

[0009] Preferably, the sealing cover is a transparent acrylic sheet; the sealing cover is equipped with a vacuum gauge.

[0010] Preferably, the base is further provided with a positioning pin for positioning the sealing cover.

[0011] The beneficial technical effects achieved by this utility model after adopting the above technical solution are as follows:

[0012] 1. A rotating mechanism is also provided on the base, fixing both the material cylinder and the stirring motor to the connecting seat. The connecting seat is rotatably sleeved onto the support column, and a cleaning chamber corresponding to the sealing cover is set along the rotation circumference of the connecting seat. A cleaning nozzle is installed inside the cleaning chamber. Because the cleaning chamber is set separately, the sealing cover needs to be rotated at a certain angle before cleaning. This prevents impurities from entering the collecting cylinder after cleaning, thus ensuring the cleanliness of the material inside the collecting cylinder. This is especially beneficial for vacuum devices, extending the service life of the equipment and further guaranteeing product quality.

[0013] 2. The cylinder cover lifting device uses a boom and a traction rope. One end of the boom is equipped with a guide block, one end of the traction rope is fixedly connected to the cylinder cover, and the other end of the traction rope is connected to a winding device. In use, the traction rope lifts the cylinder cover, facilitating the opening of the cylinder and enabling rapid feeding. Compared to using a lifting cylinder drive, the traction rope has lower requirements for installation and motion accuracy, and is also easier to maintain. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0023] See Figures 1-3 This utility model provides a gypsum mixing, filling, and vacuuming machine, comprising: a base 4, on which a mixing device 1 and a vacuuming device 2 are mounted; the mixing device 1 includes a material cylinder 11 and a stirring motor 12, the material cylinder 11 is provided with a sieve plate 13 and a stirring shaft 14; the stirring shaft 14 penetrates the sieve plate 13, and the bottom of the stirring shaft 14 is connected to the stirring motor 12 via a pulley mechanism, and several stirring blades 141 are fixed on the stirring shaft 14; in use, the material is generally fed from the top of the material cylinder 11, and after being screened by the sieve plate 13, the stirring blades 141 evenly disperse the material. To ensure that the material falls towards the discharge valve 23, the bottom center of the material cylinder 11 is arched upwards, which not only facilitates the installation of pulleys, but also allows the material to move evenly towards the discharge valve 23 under gravity during the mixing process. The pulley mechanism is prior art, see [link to relevant documentation]. Figure 2 , Figure 3 In the process, the sieve plate 13 is clamped and fixed to the material cylinder 11. A bushing is provided in the middle of the sieve. The stirring shaft 14 passes through the bushing in the middle of the sieve plate 13 and extends out from below. It is then connected to the stirring motor 12 through the pulley mechanism, and there will be no motion interference.

[0024] The vacuum device 2 includes a collection cylinder 21, with a sealing cover 22 between the material cylinder 11 and the collection cylinder 21. The sealing cover 22 has a discharge valve 23 connecting the material cylinder 11 and the collection cylinder 21. The collection cylinder 21 is connected to a vacuum pump. A vibration motor is also installed at the bottom of the collection cylinder 21. A rotating mechanism 3 is also provided on the base 4, which includes a connecting seat 31 and a support column 32. The connecting seat 31 is sleeved on the support column 32. The material cylinder 11 and the stirring motor 12 are both fixed to the connecting seat 31. Along the rotational circumference of the connecting seat 31, the base 4 also has a cleaning basin 42 corresponding to the sealing cover 22, and a cleaning nozzle (not shown) is provided inside the cleaning basin 42. This invention has two working states: one is to vacuum the gypsum inside the collection cylinder 21 to ensure it is fully filled; the other is to clean the equipment using the cleaning nozzle, especially the bottom of the sealing cover 22. Both working states are performed independently.

[0025] The rotating mechanism 3 of this utility model is also provided with a cylinder cover lifting device. The cylinder cover lifting device includes a lifting rod 33 and a traction rope 34. One end of the lifting rod 33 is provided with a guide block. One end of the traction rope 34 is fixed to the cylinder cover of the material cylinder 11, and the other end passes through the guide block or guide wheel and is then fixedly connected to a winding device (not shown). The purpose is to use a servo motor to drive the change in the length of the traction rope 34, thereby quickly opening the cylinder cover and realizing rapid feeding. After feeding is completed, it quickly falls down to seal.

[0026] The height of the lifting rod 33 in this invention is greater than the height of the support column 32. The greater height of the lifting rod 33 is used to lift the cover of the material cylinder 11 to a certain height, facilitating rapid material feeding.

[0027] The cylinder cover lifting device of this utility model also includes an angle adjusting motor 35, whose motor shaft is connected to the connecting seat 31. The connecting seat 31 is sleeved on the support column 32. The height of the cleaning basin 42 and the top of the collecting cylinder 21 are the same. Therefore, after vacuuming, the angle can be directly driven by the angle adjusting motor 35 to adjust and change the angle. The angle adjusting motor 35 can be a selected model and purchased directly as a finished product, or a common servo motor can be used with a power-off switch at the corresponding position on the positioning pin 41. When the sealing cover 22 touches the power-off switch, the power is automatically cut off.

[0028] The sealing cover 22 of this utility model is a transparent acrylic sheet; a vacuum gauge is provided on the sealing cover 22. Both the transparent acrylic sheet and the vacuum gauge are mature existing technologies with low cost. The transparent acrylic sheet is used to intuitively observe the internal situation and is relatively easy to clean, while the vacuum gauge is used to detect and report the internal air pressure value in real time.

[0029] The base 4 of this utility model is also provided with a positioning pin 41 for positioning the sealing cover 22. The positioning pin 41 is used for limiting the rotation angle and preventing large deviations. Generally, the positioning pin 41 is screwed to the base 4.

[0030] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
