It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] See also Figures 1 to 8 The utility model provides a technical solution: a feeding device for producing modulated wax for investment casting, comprising a base plate 1, a heating box 2 is installed on the top left side of the base plate 1, a motor 5 is installed on the rear side of the heating box 2, a stirring rod 8 is fixedly connected to the output end of the motor 5, a conveying frame 3 is installed on the top right side of the base plate 1, rotating shafts 11 are inserted on the upper and lower sides of the conveying frame 3, conveyor belts 9 are arranged on the outside of the two rotating shafts 11, and a plurality of fixed plates 10 are installed on the outside of the conveyor belt 9.

[0027] First, the worker puts the wax raw material into the right side of the conveying frame 3, and starts the motor 5 to drive the stirring rod 8 to rotate. Then, the ingredients are added one by one through the feed port on the top of the heating box 2, and the conveyor belt 9 is driven to rotate counterclockwise through the two rotating shafts 11. At the same time, the fixed plate 10 on the outside of the conveyor belt 9 is driven to rotate, and the wax raw material is conveyed to the inside of the heating box 2 through the discharge port on the left side of the conveying frame 3. At the same time, the fixed plate 10 is fitted with the inner wall of the conveying frame 3 to prevent the wax raw material from being stuck in the gap between the fixed plate 10 and the conveying frame 3 during the conveying process, thereby facilitating the use of the workers and reducing the labor intensity of the workers.

[0028] Embodiment 2

[0029] On the basis of Example 1, in order to achieve the conveying of the conveyor belt 9 while stirring to reduce the cost of use, one of the driving wheels 4 is installed at the rear end of the lower rotating shaft 11, and another driving wheel 4 is installed on the outer side of the rear part of the stirring rod 8. The outer sides of the two driving wheels 4 are provided with a driving belt 6, so that the stirring rod 8 and the lower rotating shaft 11 can rotate synchronously through the rotation of the two driving wheels 4, and the wax raw material can also be transported during the stirring process to reduce the cost of use of the feeding device; the front and rear sides of the fixed plate 10 are both in contact with the inner wall of the conveying frame 3, the lower rotating shaft 11 passes through the rear side of the conveying frame 3 and the front end is rotatably connected to the front side of the conveying frame 3.

[0030] While the stirring rod 8 is rotating, since one of the driving wheels 4 is installed on the outer side of the stirring rod 8, and another driving wheel 4 is installed on the rear end of the lower rotating shaft 11, and the two driving wheels 4 are connected by a driving belt 6, the lower driving wheel 4 is driven to rotate during the stirring process of the stirring rod 8, and then the conveyor belt 9 is driven to transport the wax raw material, so as to achieve a linkage effect, reduce the use of driving components, and thus reduce the use cost of the feeding device.

[0031] Embodiment 3

[0032] On the basis of Example 2, in order to facilitate the workers to subsequently clean up the residual wax raw materials inside the conveying frame 3, a baffle 7 is hinged on the right side of the conveying frame 3, a slot 12 is provided on the right side of the baffle 7, and a slide groove 13 is provided on the upper right side of the conveying frame 3. The inner wall of the slide groove 13 is slidably connected to a limit plate 16, a pin 14 is installed in the middle of the limit plate 16, and a return spring 15 is sleeved on the outer side of the pin 14.

[0033] After long-term use, there will be residual wax raw materials inside the conveying frame 3. At this time, the pin 14 is pulled upward to drive the limit plate 16 to move upward along the inner wall of the slide groove 13, and the reset spring 15 is squeezed at the same time, so that the bottom end of the pin 14 is disengaged from the slot 12, and then the worker opens the baffle 7 to clean the inside of the conveying frame 3. After cleaning, the worker resets the baffle 7 and releases the pin 14 at the same time, so that it is driven by the elastic force of the reset spring 15 and continues to be plugged into the inner wall of the slot 12, thereby jamming the baffle 7 to facilitate the worker's subsequent cleaning.

[0034] Embodiment 4

[0035] On the basis of the third embodiment, in order to facilitate the reset of the latch pin 14, one end of the reset spring 15 is installed on the top wall of the slide groove 13, and the other end of the reset spring 15 is installed on the top of the limit plate 16, so that the latch pin 14 is reset by the elastic force of the reset spring 15; the latch pin 14 passes through the upper right side of the conveying frame 3, and the lower end of the latch pin 14 is inserted into the inner wall of the slot 12, so as to facilitate the clamping of the baffle 7.

[0036] After the cleaning is completed, since the reset spring 15 is in a squeezed state, when the worker releases the latch 14, the reset spring 15 will push the limit plate 16 to move downward along the inner wall of the slide groove 13, thereby synchronously driving the latch 14 to move downward, and allowing the latch 14 to continue to be inserted into the inner wall of the slot 12, thereby facilitating the reset of the latch 14 to facilitate subsequent cleaning by workers.

[0037] During actual use, the worker first puts the wax raw material into the right side of the conveying frame 3 through the feed port, and starts the motor 5 to drive the stirring rod 8 to rotate. Then, the ingredients are added one by one through the feed port on the top of the heating box 2, and the conveyor belt 9 is driven to rotate counterclockwise through the two rotating shafts 11. At the same time, the fixed plate 10 on the outside of the conveyor belt 9 is driven to rotate, and the wax raw material is conveyed to the inside of the heating box 2 through the discharge port on the left side of the conveying frame 3. At the same time, the fixed plate 10 is fitted with the inner wall of the conveying frame 3, so as to prevent the wax raw material from being stuck in the gap between the fixed plate 10 and the conveying frame 3 during the conveying process, thereby facilitating the use of the workers and reducing the labor intensity of the workers.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
