Description

Technical Field

[0001] This utility model relates to the field of jewelry manufacturing technology, specifically a wax resin base cleaning device. Background Technology

[0002] The wax tree structure is a method of manufacturing metal jewelry in the jewelry industry. It involves combining multiple wax models into a single structure, followed by a lost-wax casting process for small-batch production. A wax tree consists of a wax core, sprue, and wax model. The wax tree is mounted on a base, typically a shallow cylinder with an open top and a base plate. A raised cone-shaped section at the center of the base plate has a hole; the wax core is inserted into this hole for positioning the wax tree. During jewelry making, wax drips onto the cone-shaped section of the wax tree base. After solidification, a wax film forms. For reuse, this film must be removed from the cone. Current technology typically uses brushes to remove this film, but this method has drawbacks: wax tends to stick to the brush, leaving residue after cleaning several wax tree bases, affecting usability; and the brush's cleaning efficiency is relatively low. Utility Model Content

[0003] This invention addresses the problems of wax film sticking to the brush and low removal efficiency when wiping the wax film off the conical body of the wax resin holder in existing technologies. It provides a wax resin holder cleaning device that can quickly remove residual wax film from the wax resin holder.

[0004] To solve the above-mentioned technical problems, the structural features of this utility model are as follows: it includes a frame, on which at least one blade is provided for scraping the wax film on the surface of a conical body of a wax resin seat. The cutting edge of the blade can fit against the surface of the conical body. The blade is mounted on a blade holder. The frame is also equipped with a power device that can drive the blade holder to rotate. The power device is electrically connected to a controller.

[0005] With the above structure, when scraping off the wax film on the conical surface of the wax resin holder, the conical body of the wax resin holder is attached to the cutting edge of the blade. The power unit is activated by the controller, and the power unit drives the blade holder to rotate. The blade on the blade holder rotates synchronously, and the cutting edge scrapes off the wax film on the conical surface as the blade rotates. This wax resin holder cleaning device removes the wax film on the conical body of the wax resin holder by rotating the blade. The wax film is less likely to stick to the cutting edge of the blade. The device has a simple structure, is easy to use, and can quickly scrape off the wax film on the surface of the conical body of the wax resin holder, improving removal efficiency.

[0006] The power output end of the power device is connected to the rotating drum, the tool holder is fixedly connected to the rotating drum, and the rotating drum, tool holder, and blade rotate around a vertical axis.

[0007] The blade holder and blade are provided with a protective cover. A pressure control disc for controlling the start and stop of the power device is fixedly connected to the top of the protective cover. A pressure sensor is provided on the pressure control disc. The pressure sensor is electrically connected to the controller. A second through hole is provided on the pressure control disc, through which a conical body of a wax resin seat can pass. After passing through the second through hole, the conical body fits against the cutting edge of the blade.

[0008] Above the pressure control disc is a limiting disc for limiting the wax resin seat. The lower surface of the limiting disc is in contact with the upper surface of the pressure control disc. The limiting disc has a first through hole that communicates with the second through hole. The cone can pass through the first through hole, but the wax resin seat cannot pass through the first through hole as a whole. After the cone passes through the first through hole and is in contact with the cutting edge, the bottom plate or edge of the wax resin seat abuts against the upper surface of the limiting disc.

[0009] The protective cover is provided with a chip collection groove at the bottom for collecting the scraped wax chips.

[0010] This utility model discloses a wax resin holder cleaning device. When the blade rotates, its cutting edge scrapes away the residual wax film on the wax resin holder. The blade is mounted on a blade holder, and a power unit drives the blade and blade holder to rotate via a rotating drum. A protective cover is installed outside the blade and blade holder to prevent the scraped wax shavings from splashing and to prevent workers from getting too close to the blade and being injured. A pressure control plate with a pressure sensor is located on the top of the protective cover. A limit plate is located above the pressure control plate. When cleaning the wax resin holder, the conical body of the wax resin holder is inserted downwards through the limit plate and the pressure control plate. When the conical body of the wax resin holder comes into contact with the cutting edge of the blade... When pressing the wax resin holder, the limit plate blocks the bottom plate or edge from passing through. Continue pressing the wax resin holder, and the pressure is transmitted to the pressure control plate through the limit plate. When the pressure sensor detects that the pressure has reached the set value, the power unit is started through the controller. The power unit drives the blade to rotate and scrape off the wax film on the conical body of the wax resin holder. Then stop pressing the wax resin holder, the pressure applied to the pressure control plate disappears, the pressure sensor shuts off the power unit through the controller, and the wax resin holder can be removed. The operation is simple. The scraped wax falls into the chip collection groove. The wax film removal process on the conical body of the wax resin holder is fast, which improves the wax film removal efficiency. Attached Figure Description

The base plate 171 and the rim 172 are cylindrical, open at one end and closed at the other. A raised conical body 173 is located at the center of the base plate 171. The direction of the raised conical body 173 is the same as that of the rim 172, and the height of the raised conical body 173 is greater than that of the rim 172. A mounting hole 174 is located at the center of the conical body 173, with the axis of the mounting hole 174 being the same as the direction of the raised conical body 173. When in use, the conical body 173 faces upwards, i.e.,... Figure 11 (a) Figure 11 (b) The wax resin holder 17 is rotated 180° in the vertical plane, and the wax core of the wax tree is inserted into the mounting hole 174. When the cleaning device of this utility model is used to remove the wax film on the surface of the cone 173, the cone 173 faces downwards. Figure 11 (a) Figure 11 (b) state.

[0024] Reference Figure 1-10 The present invention relates to a wax resin seat cleaning device, comprising a frame 1, on which at least one blade 14 for scraping the wax film on the surface of the conical body 173 of the wax resin seat 17 is provided, a blade holder 13 for mounting the blade 14, a power device for driving the blade holder 13 and the blade 14 to rotate, and a controller 10. The power device is electrically connected to the controller 10, and the controller 10 controls the start and stop of the power device. After the power device is started, it drives the blade holder 13 and the blade 14 mounted on the blade holder 13 to rotate. The cutting edge 141 of the blade 14 can fit against the surface of the conical body 173 of the wax resin seat 17. When the blade 14 rotates, the cutting edge 141 scrapes off the residual wax film on the surface of the conical body 173 of the wax resin seat 17. The figure shows three blades 14, but two or other numbers of blades 14 can also be used. The frame 1 in the figure includes four legs 101 arranged in a rectangle. The top of the legs 101 is fixedly connected to a rectangular top plate 103. Side plates 102 are connected between two adjacent legs 101. The legs 101, side plates 102, and top plate 103 form a rectangular box-shaped frame 1. The power unit and controller 10 are installed in the box space. The panel of the controller 10 is embedded in a side plate 102. The tool holder 13, blades 14, etc. are installed above the top plate 103. Of course, the frame 1 can also adopt other forms, such as not setting the side plate 102, as long as the power unit, tool holder 13, blades 14, and other components can be installed.

[0025] Reference Figure 1-10The power unit includes a motor 11. The power output end of the motor 11 is usually connected to the reducer. The power unit is existing technology and will not be described in detail here. The power unit is installed in the housing of the frame 1. Specifically, the power unit can be fixed below the top plate 103 using fasteners such as bolts and nuts. A rotating drum 7 is provided above the top plate 103. The bottom of the rotating drum 7 passes through the top plate 103 and is connected to the power output shaft 12 of the reducer of the power unit. The power unit drives the rotating drum 7 to rotate around the vertical axis. The tool holder 13 is fixedly installed on the top of the rotating drum 7. The tool holder 13 and the blade 14 rotate around the rotating shaft of the rotating drum 7. Specifically, the tool holder 13 is suspended and fixedly supported above the rotating drum 7 by multiple second support rods 15. The two ends of the second support rods 15 are provided with external threads. The two ends of the second support rods 15 are fixedly connected to the tool holder 13 and the rotating drum 7 respectively by nuts. Of course, welding or other fixing methods can also be used.To prevent the scraped wax shavings from splashing around, a protective cover 2 is provided on the outside of the blade holder 13 and the blade 14. The protective cover 2 also prevents operators from getting too close and causing personal injury. The protective cover 2 is fixedly connected to the support plate 8, which is suspended above the frame 1 by multiple first support rods 3. The two ends of the first support rods 3 are fixedly connected to the top plate 103 and the support plate 8, respectively, using the same connection method as the second support rod 15. A third through hole 801 is provided on the support plate 8. The diameter of the third through hole 801 is larger than the diameter of the rotating drum 7, and the rotating drum 7 passes through the third through hole 801. A pressure control disc 5 is fixedly connected to the top of the rotating cylinder 7. A limit disc 4 is provided above the pressure control disc 5. The lower surface of the pressure control disc 5 is in contact with the upper surface of the pressure control disc 5. The limit disc 4 and the pressure control disc 5 can be connected to the top of the rotating cylinder 7 by screws, bolts, or nuts. A first through hole 401 is provided on the limit disc 4, and a second through hole 501 is provided on the pressure control disc 5. The first through hole 401 and the second through hole 501 are connected. The conical body 173 of the wax resin seat 17 can pass through the first through hole 401 and the second through hole 501 and be in contact with the cutting edge 141 of the blade 14, but the wax resin seat 17 cannot be completely penetrated. Through the first through hole 401, where the diameter of the first through hole 401 is smaller than the dimensions of the base plate 171 and the surrounding edge 172 of the wax resin seat 17, when the conical body 173 passes through the first through hole 401 and fits against the cutting edge 141, the base plate 171 or the surrounding edge 172 abuts against the upper surface of the limiting plate 4, preventing the wax resin seat 17 from passing through the first through hole 401. The conical body 173 then passes downward through the first through hole 401, and the limiting plate 4 limits the position of the wax resin seat 17 during cleaning. A pressure sensor is provided on the pressure control plate 5, which is electrically connected to the controller 10. The pressure sensor detects pressure from the limiting plate 4. When the pressure-controlled motor 11 starts and stops, and the wax film on the surface of the conical body 173 is removed, after the base plate 171 or the rim 172 of the wax resin seat 17 abuts against the upper surface of the limiting plate 4, the wax resin seat 17 is pressed down. The pressure sensor detects that the pressure from the limiting plate 4 increases. When the pressure reaches the set value, the motor 11 is started by the controller 10. The motor 11 drives the knife holder 13 and the blade 14 to rotate. The cutting edge 141 scrapes off the wax film on the surface of the conical body 173. After a certain period of time, the pressure on the wax resin seat 17 is stopped. The pressure from the limiting plate 4 is less than the set value. The pressure sensor stops the motor 11 through the controller 10.

The gaps 132 are perpendicular to the circular surface of the tool holder 13 and do not extend to the center of the circular surface. The tool holder 13 in the figure has three gaps 132, evenly distributed along the circular surface of the tool holder 13, dividing the tool holder 13 into three fan-shaped spacer blocks 131. Each spacer block 131 has a countersunk through hole 133 and a threaded hole 134. The countersunk through holes 133 on adjacent spacer blocks 131... The 33 and threaded hole 134 are coaxial. The disc surface of the blade 14 has a positioning through hole 142 for mounting the blade 14. During installation, the blade 14 is inserted into the gap 132. The positioning through hole 142 is connected to the countersunk through hole 133 and threaded hole 134 on the two adjacent spacer blocks 131. The hexagonal head bolt passes through the countersunk through hole 133 and positioning through hole 142 and is screwed into the threaded hole 134. After installation, the blade 14 can rotate slightly around the hexagonal head bolt, which allows the cone 173 to fit better with the cutting edge 141. The protective cover 2 has a chip collection groove 9 below it. The chip collection groove 9 is fixedly installed on the upper surface of the top plate 103. The chip collection groove 9 is located directly below the third through hole 801. The wax chips scraped off inside the protective cover 2 fall into the chip collection groove 9.
