DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] like Figure 1-Figure 2 As shown, this embodiment discloses a feeding mixer, comprising a mixing drum 1, a cover 11 mounted on top of the mixing drum 1, and a feed channel 111 provided on the cover 11 for feeding materials. During use, a viscous liquid raw material is first placed in the mixing drum 1, and then a powdered solid is added to mix with the liquid in the mixing drum 1.

[0026] like Figure 1 As shown, a driving component 42 is installed on the upper end of the cover 11. The driving component 42 is an oil cylinder. The top output end of the driving component 42 is installed with a plate 4, and the plate 4 is located above the cover 11. The mixing drum 1 is installed with a motor 41. The output end of the motor 41 is connected to a gear pair 411. One size of the gear pair 411 is connected to the rod 3. The rod 3 rotates along its own axis under the drive of the motor 41. The rod 3 can move up and down under the drive of the driving component 42. The plate 4 is installed with a base 43. The rod 3 passes through the base 43. The rod 3 and the base 43 are connected by a bearing 44. The rod 3 passes through the cover 11, and the bottom of the rod 3 is inserted into the mixing drum 1. The rod 3 is installed with a blade 1 31 and a blade 2 32. When the rod 3 rotates, it drives the blade 1 31 and the blade 2 32 to form stirring in the mixing drum 1.

[0027] like Figure 1 、 Figure 2As shown, a fixing sleeve 33 is fixedly mounted at the bottom of the rod body 3, and a pressure pad 34 is fixedly mounted at the bottom of the fixing sleeve 33. A groove 342 is provided at the top of the pressure pad 34, and the groove 342 is in the shape of an inverted T. A pull rod 35 is installed on the fixing sleeve 33, and the pull rod 35 passes through the fixing sleeve 33. The pull rod 35 includes an extension portion 351 at the bottom. The extension portion 351 is inserted into the groove 342 and hooks onto the wall of the groove 342 to prevent the pressure pad 34 from falling off. The pressure pad 34 is made of rubber.

[0028] like Figure 1 As shown, the mixing drum 1 includes an extension drum 12 located at the bottom, and a bracket body 5 is installed on the inner wall of the extension drum 12. The bracket body 5 is provided with a plurality of through holes 51. The through holes 51 pass through the bracket body 5 from top to bottom. A discharge channel 121 is provided at the bottom of the extension drum 12, and the discharge channel 121 is connected to a valve 2.

[0029] Combine Figure 1 、 Figure 2 The bracket body 5 is provided with a countersunk hole 53, which opens at the top of the bracket body 5. The bracket body 5 is also provided with a pipe connection passage 52, which communicates with the countersunk hole 53. The outer wall of the extension barrel 12 is provided with a through hole 122, which communicates with the pipe connection passage 52. A sealing gasket is installed between the inner wall of the extension barrel 12 and the outer wall of the bracket body 5 to seal the connection between the through hole 122 and the pipe connection passage 52, thereby isolating the pipe connection from the inner cavity of the mixing drum 1. The pipe connection passage 52 is used to connect the pipeline line to the countersunk hole 53.

[0030] like Figure 2 As shown, the bracket body 5 is mounted with a sleeve body 6, and an elastic sleeve 9 is mounted on the inner wall of the sleeve body 6. The elastic sleeve 9 includes an extension ring 91 at the bottom. The sleeve body 6 and the bracket body 5 press the extension ring 91 up and down, and the outer circumference of the elastic sleeve 9 is in contact with the inner circumference of the sleeve body 6. The bottom of the countersunk hole 53 is mounted with a second drive component 85. The second drive component 85 is a cylinder. The output end of the second drive component 85 is mounted with a moving block 8. The moving block 8 can move up and down under the drive of the second drive component 85.

[0031] The elastic sleeve 9 is closed at the top and open at the bottom. The moving block 8 is inserted into the elastic sleeve 9 through the bottom opening of the elastic sleeve 9. The top of the moving block 8 abuts the inner wall of the elastic sleeve 9. The outer peripheral wall of the moving block 8 stretches the inner peripheral wall of the elastic sleeve 9 so that the outer wall of the moving block 8 and the inner wall of the sleeve body 6 press the elastic sleeve 9 together to form a seal. A third groove 81 is provided on both sides of the moving block 8. A connecting hole 82 is connected between the two third grooves 81. A spring 83 is placed in the connecting hole 82. A pressure block 84 is slidably connected to the third groove 81. The axial ends of the spring 83 abut the pressure blocks 84 on both sides. The pressure blocks 84 and the inner wall of the sleeve body 6 press the elastic sleeve 9 together. In the radial cross-section of the moving block 8, the outer wall of the pressure block 84 is arc-shaped. The outer wall surface of the pressure block 84 abuts the inner wall surface of the elastic sleeve 9. As the moving block 8 moves upward, the elastic sleeve 9 stretches upward, and the wall surface of the elastic sleeve 9 becomes thinner. By providing the pressure block 84, the wall surface of the elastic sleeve 9 becomes thinner, which also plays an auxiliary sealing role and improves the sealing effect.

[0032] like Figure 2 As shown, the sleeve 6 includes an end portion 61 at the top, which is provided with a groove 611 extending vertically through the end portion 61. The pressure pad 34 has a protrusion 341 at the bottom, which can be moved downward to be inserted into the groove 611, thereby separating the internal cavity of the sleeve 6 from the internal cavity of the mixing drum 1.

[0033] like Figure 2 As shown, the sleeve body 6 is provided with a third through hole 62 , the mixing drum 1 is provided with an insertion hole 13 , the material pipe 7 passes through the material pipe 7 , and the third through hole 62 is connected to an external feeding device through the material pipe 7 . Figure 2 The outer wall of the middle elastic sleeve 9 blocks the through hole three 62. When the moving block 8 moves downward to the limit position, the elastic sleeve 9 contracts downward with the moving block 8 to connect the through hole three 62 with the groove one 611. The solid powder raw material enters the cavity of the sleeve body 6 from the through hole three 62 and can pass out from the groove one 611. Since the liquid first placed in the mixing drum 1 has a certain viscosity, the solid powder placed later sinks slowly, resulting in low mixing efficiency. By setting the groove one 611 at a lower position of the mixing drum 1, the solid powder passed out of the groove one 611 is directly mixed with the liquid at the lower position of the mixing drum 1, thereby improving the overall mixing efficiency.

[0034] When the elastic sleeve 9 is stretched upward, the elastic sleeve 9 can close the through hole three 62, and the inner wall of the elastic sleeve 9 can fit with the inner wall of the end 61 to close the groove one 611. During the upward stretching process of the elastic sleeve 9, the material in the inner cavity of the sleeve body 6 is discharged from the groove one 611.

[0035] The feeding method of the above-mentioned feeding mixer is as follows:

[0036] ① The rod body 3 moves upward under the driving action of the driving component 42, and the protrusion 341 and the groove 611 are separated from each other.

[0037] ② The moving block 8 moves upward to stretch the elastic sleeve 9 so that the top of the elastic sleeve 9 fits against the inner wall of the top of the end 61, and the material in the sleeve body 6 is squeezed out from the groove 1 611, and the elastic sleeve 9 closes the lower end of the groove 1 611.

[0038] ③ The rod body 3 moves downward under the driving action of the driving component 42, the protrusion 341 is inserted into the groove 611, and the pressure pad 34 closes the upper end of the groove 611.

[0039] ④ The moving block 8 moves downward to the elastic sleeve 9 to open the through hole three 62, the elastic sleeve 9 is separated from the inner wall of the top of the end 61, and the through hole three 62 is connected to the groove one 611. Since the upper end of the groove one 611 is closed by the pressure pad 34, a cavity is formed between the inner wall of the sleeve body 6 and the outer wall of the elastic sleeve 9, and the solid powder material is injected into the cavity through the through hole three 62.

[0040] When the protrusion 341 is inserted into the groove 1 611 , a small amount of material pressed into the groove 1 611 will also enter the sleeve 6 , but will not affect the cavity between the inner wall of the sleeve 6 and the outer wall of the elastic sleeve 9 . Most of the material is solid powder material that is driven in.

[0041] ⑤ The moving block 8 moves upward until the elastic sleeve 9 closes the through hole three 62, and the rod body 3 moves upward under the driving action of the driving component 1 42, and the protrusion 341 and the groove 1 611 are separated from each other.

[0042] ⑥ The moving block 8 continues to move upward, and the material in the sleeve body 6 is pushed out of the groove 1 611.

[0043] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
