Description

Technical Field

[0001] The invention relates to the technical field of rosin processing, in particular to a rosin crusher for preparing rosin water. Background Art

[0002] Rosin, also known as rosin, is a substance obtained by distilling the resin contained in pine trees. It is solid, transparent, light yellow or brown in color, hard and brittle, insoluble in water but soluble in alcohol. It can be used in industry, flux, Chinese herbal medicine, stringed instruments, etc. Rosin water is a liquid made by dissolving rosin powder in alcohol. It is a flux commonly used in tin wire welding. It can remove oxides and keep the metal welding surface clean and lubricated for excellent welding. Therefore, rosin needs to be crushed into powder during processing.

[0003] When the existing rosin grinders are feeding the rosin, most of them are fed manually or in batches by placing the rosin in a feeding funnel. This feeding method has the defect of uneven feeding. In the initial and final stages of the grinding, the rosin can be ground into finer powder due to the small amount of rosin. In the middle stage of the grinding, a large amount of rosin flows into the grinding barrel, which easily leads to incomplete grinding of the rosin and relatively coarse powder.

[0004] Based on this, it is necessary to design a rosin crusher for preparing rosin water with a uniform feeding function. Summary of the invention

[0005] The technical scheme of the present invention is: a rosin pulverizer for preparing rosin water comprises a frame, a pulverizing barrel, a cover plate, a feeding barrel, a rotating shaft, a feeding pipe, a material leveling and adjusting control unit, a power motor, a pulley assembly, a pulverizing assembly and a transmission mechanism. The pulverizing barrel and the power motor are installed on the frame. The bottom and one longitudinal side of the pulverizing barrel are opened. The edge of one side of the opening of the pulverizing barrel is rotatably provided with a cover plate for sealing the opening. The pulverizing barrel has a pulverizing assembly for pulverizing rosin. The power motor drives the pulverizing assembly through the pulley assembly to perform pulverizing operation. The feeding pipe is provided with a pulverizing barrel and a power motor. The cylinder is connected to the inner cavity of the crushing cylinder through a feeding pipe, and a material mixing and adjusting control unit is connected to the inner cavity of the feeding cylinder through a rotating shaft. The material mixing and adjusting control unit is used to evenly feed the rosin in the inner cavity of the feeding cylinder into the feeding pipe. The crushing cylinder is provided with a transmission mechanism for transmitting the power output by the driving motor to a point on the rotating shaft to realize the regular flipping of the material mixing and adjusting control unit by 180 degrees. The transmission mechanism includes a transmission assembly and a lifting assembly. When the lifting assembly is lifted, the rotating shaft 1 is driven by the transmission assembly to perform forward and reverse rotation motion to enable the material mixing and adjusting control unit to perform a reciprocating 180-degree rotation motion.

[0006] Furthermore, the crushing assembly includes a crushing piece 1, a crushing piece 2 and a rotating shaft 2. The crushing piece 1 is installed on the inner wall of the cover plate, and the crushing piece 2 is rotatably connected to the side wall of the crushing barrel opposite to the cover plate through the rotating shaft 2. The crushing piece 2 cooperates with the crushing piece 1 to crush the rosin into powder, and the rotating shaft 2 passes through the end of the crushing barrel and is connected to the pulley assembly.

[0007] Furthermore, a filter ring is rotatably arranged in the pulverizing cylinder to filter the crushed rosin powder.

[0008] Furthermore, a blowing assembly is provided above the pulverizing cylinder for compressing the gas and blowing it onto the filter ring to avoid clogging of the filter ring. The blowing assembly includes a booster box, a vertical rod, a push plate, an output air pipe 1, a one-way valve 1, an input air pipe, a one-way valve 2, an output air pipe 2, a three-way pipe, an output main pipe and an arc-shaped exhaust frame. A booster box is provided above the pulverizing cylinder, and a push plate adapted to the booster box is slidably provided inside the booster box. Vertical rods are symmetrically provided at the bottom of the push plate, and the vertical rods pass through the bottom of the booster box. At least one output air pipe 1 and one output air pipe 2 are provided at the top and bottom of the booster box respectively. The output air pipe 1 and the output The air pipes 2 are connected to the output main pipe through a three-way pipe. The output air pipes 1 and 2 are both provided with one-way valves 1, which are used to control the output air pipes 1 and 2 for one-way output. Input air pipes are provided at the top and bottom of the booster box. The input air pipes are provided with one-way valves 2, which are used to control the input air pipes for one-way input. The output main pipe passes through the pulverizing cylinder and is connected to an arc-shaped exhaust frame at the end. The arc-shaped exhaust frame is arranged in the inner cavity of the pulverizing cylinder and is arranged directly above the filter ring. The pulverizing cylinder is provided with a lifting component for driving a push plate to perform lifting operations to compress and transport the gas.

[0009] Furthermore, the lifting assembly includes a reducer, a turntable, a transmission plate, a guide rod and a mouth plate. The lower end of the vertical rod is connected to the mouth plate, and the transmission plate is rotatably connected to the mouth plate. A reducer is arranged on the outer wall of the crushing cylinder, and the second rotating shaft is connected to the input shaft of the reducer. The turntable is connected to the output shaft of the reducer. The lower end of the transmission plate is connected to the non-center point of the turntable. Guide rods are arranged on both sides of the booster box to provide guidance for the lifting and lowering of the mouth plate, and the guide rods slide through the mouth plate.

[0010] Furthermore, a transmission assembly for converting the lifting motion of the mouth plate into a rotational motion of the rotating shaft is provided on the outer wall of the loading barrel, and the transmission assembly includes a gear installed on one end of the rotating shaft and a transmission rack connected to the mouth plate, and the transmission rack is meshed with the gear.

[0011] Furthermore, it also includes a discharge funnel, a mouth frame, a collecting bag and a sliding plate. The bottom opening of the grinding cylinder is connected to the discharge funnel, and a mouth frame is arranged on the frame. The mouth frame is arranged directly below the bottom opening of the grinding cylinder. A sliding plate is slidably arranged at the bottom of the mouth frame. The bottom of the discharge funnel is connected to a collecting bag for collecting rosin powder, and the collecting bag is placed on the sliding plate.

[0012] Furthermore, a latch is movably arranged on the sliding plate, and the latch passes through the sliding plate and the mouth frame in sequence from top to bottom.

[0013] Furthermore, the diameter of the circular hole on the filter ring is larger than the diameter of the circular hole on the arc-shaped exhaust frame.

[0014] Furthermore, the number of teeth on the transmission rack is half the number of teeth on the gear.

[0015] The beneficial effects are: 1. The power motor drives the lifting component to perform lifting movement through the pulley component. When the lifting component is lifting, it drives the rotating shaft 1 to rotate half a circle forward and backward through the transmission component. The rotating shaft 1 drives the material leveling control unit to perform 180-degree reciprocating rotation, so that the rosin in the upper part of the inner cavity of the feeding barrel is evenly and quantitatively transported to the feeding pipe, and then transported to the crushing barrel through the feeding pipe for crushing operation, so as to achieve the effect of uniform feeding of the rosin, thereby realizing the function of efficiently crushing the rosin into rosin powder.

[0016] 2. When the mouth plate is lifted and lowered, the mouth plate drives the push plate to lift and lower through the vertical rod, thereby compressing and pressurizing the gas in the booster box, and delivering the compressed gas to the output main pipe through the output air pipe 1 or the output air pipe 2. The compressed gas is input into the arc exhaust frame through the output main pipe and blown onto the filter ring through the arc exhaust frame, so as to blow away the rosin powder in the circular holes on the filter ring, thereby maintaining the filtering efficiency of the filter ring.

The front right side of the crushing barrel 2 is rotatably provided with a T-shaped locking handle 202 for fixing the cover plate 201 on the crushing barrel 2. The crushing barrel 2 has a crushing assembly for crushing rosin. The power motor 6 drives the crushing assembly to perform a crushing operation through the pulley assembly 61. The pulley assembly 61 includes a transmission mechanism connected to the power motor 6. A pulley connected to the output shaft, a pulley connected to the input shaft of the crushing component and a flat belt between the two pulleys, the loading barrel 3 is connected to the inner cavity of the crushing barrel 2 through the feeding pipe 4, the feeding pipe 4 passes through the cover plate 201, and a material mixing and adjusting control unit 5 is rotatably connected to the loading barrel 3 through a rotating shaft 301.

There is a certain gap between the crushing head of the crushing piece 2 9 and the crushing head of the crushing piece 1 8. When the crushing head of the crushing piece 2 9 moves circumferentially around the crushing head of the crushing piece 1 8, the crushing head of the crushing piece 2 9 crushes the rosin and grinds it into powder in the rotating motion. A pulley is provided on the end of the rotating shaft 12 passing through the crushing cylinder 2, and the power motor 6 drives the rotating shaft 2 12 to make selective motion through the pulley assembly 61.

[0029] like Figure 3 , Figure 4 and Figure 5As shown, a filter ring 11 is rotatably arranged in the pulverizing cylinder 2 for filtering the crushed rosin powder. The filter ring 11 is arranged between the pulverizing component and the inner wall of the pulverizing cylinder 2. The rosin powder pulverized by the pulverizing component falls on the filter ring 11, and the rosin powder is screened by the filter ring 11. A blowing component for compressing the gas and blowing it onto the filter ring 11 to avoid clogging of the filter ring 11 is arranged above the pulverizing cylinder 2. The blowing component includes a booster box 16, a vertical rod 19, a push plate 20, an output air pipe 1 21, a one-way valve 1 22, an input air pipe 23, a one-way valve 24, an output air pipe 25, a three-way pipe 26, an output main pipe 27 and an arc-shaped exhaust frame 28. A boost box 16 is provided, and a push plate 20 adapted thereto is slidably provided inside the boost box 16. A vertical rod 19 is symmetrically provided at the bottom of the push plate 20, and the vertical rod 19 passes through the bottom of the boost box 16. Four output air pipes 1 21 and output air pipes 2 25 are correspondingly provided at the top and bottom of the boost box 16. The output air pipes 1 21 and the output air pipes 2 25 are both connected to the output main pipe 27 through a three-way pipe 26. A one-way valve 1 22 is provided on the output air pipes 1 21 and the output air pipes 2 25. The one-way valve 1 22 is used to control the output air pipes 1 21 and the output air pipes 2 25 to perform one-way output, and when the one-way valve 1 22 on the output air pipe 1 21 is opened, the one-way valve 1 22 on the output air pipe 2 25 is in a closed state. Similarly, the top and bottom of the booster box 16 are both provided with an input air pipe 23, and a one-way valve 24 is provided on the input air pipe 23. The one-way valve 24 is used to control the input air pipe 23 for one-way input. When the one-way valve 24 on the upper input air pipe 23 is opened, the one-way valve 24 on the lower input air pipe 23 is closed. Similarly, the output main pipe 27 passes through the pulverizing cylinder 2 and is connected to an arc-shaped exhaust frame 28 at the end. The arc-shaped exhaust frame 28 is arranged in the inner cavity of the pulverizing cylinder 2 and is arranged directly above the filter ring 11. The diameter of the circular hole on the filter ring 11 is larger than the diameter of the circular hole on the arc-shaped exhaust frame 28. The pulverizing cylinder 2 is provided with a driving push plate 20 for lifting and lowering to realize the gas inlet. The lifting assembly for compression and transportation, when the lifting assembly pushes the push plate 20 to rise, the one-way valve 24 located on the lower input air pipe 23 is in an open state. At this time, due to the upward movement of the push plate 20, the lower part of the booster box 16 is in a negative pressure state, and the one-way valve 1 22 on the output air pipe 25 is in a closed state. The gas enters the booster box 16 through the lower input air pipe 23. The push plate 20 moves upward to compress the gas in the original booster box 16 and outputs it to the output main pipe 27 through the output air pipe 1 21. Conversely, the gas is input into the arc-shaped exhaust frame 28 through the output main pipe 27 and blown onto the filter ring 11 through the through hole of the arc-shaped exhaust frame 28, thereby blowing away the rosin powder in the through hole of the filter ring 11.

[0030] like Figure 4 and Figure 5As shown, the lifting assembly includes a reducer 13, a turntable 14, a transmission plate 15, a guide rod 17 and a mouth plate 18. The lower end of the vertical rod 19 is connected to the mouth plate 18, and the transmission plate 15 is rotatably connected to the mouth plate 18. The reducer 13 is arranged on the left outer wall of the crushing cylinder 2, and the second shaft 12 is connected to the input shaft of the reducer 13. Here, the second shaft 12 is used as the input shaft of the reducer 13. The turntable 14 is connected to the output shaft of the reducer 13. The lower end of the transmission plate 15 is connected to the non-center point of the turntable 14, thereby achieving the effect of the turntable 14 driving the transmission plate 15 to move up and down. The left and right sides of the booster box 16 are provided with guide rods 17 to provide guidance for the lifting and lowering of the mouth plate 18, and the guide rods 17 slide through the mouth plate 18.

[0031] like Figure 6 As shown, a transmission assembly for converting the lifting movement of the mouth plate 18 into the rotational movement of the rotating shaft 301 is arranged on the outer wall of the feeding barrel 3, and the transmission assembly includes a gear 29 installed at the end of the rotating shaft 301 and a transmission rack 30 connected to the mouth plate 18, the transmission rack 30 is meshed with the gear 29, the number of teeth of the transmission rack 30 is half the number of teeth of the gear 29, and a one-way clutch for enabling the one-way rotation of the rotating shaft 301 can be arranged at the connection between the gear 29 and the rotating shaft 301, and the setting of the one-way clutch can realize that when the transmission rack 30 moves upward, the transmission rack 30 drives the gear 29 to drive the rotating shaft 301 to rotate half a circle clockwise, and the material mixing and adjusting control unit 5 rotates 180 degrees, thereby rotating the rosin on the upper part of the material mixing and adjusting control unit 5 by 180 degrees and sending it into the feeding pipe 4, and when the transmission rack 30 moves downward, the transmission rack 30 drives the gear 29 to idle, thereby reserving a suitable time for the crushing assembly to crush the rosin in the crushing barrel 2.

[0032] like Figure 7 and Figure 8 As shown, it also includes a discharge funnel 31, a mouth frame 32, a collecting bag 33 and a sliding plate 34. The bottom opening of the pulverizing cylinder 2 is connected to the discharge funnel 31, and a mouth frame 32 is arranged on the frame 1. The mouth frame 32 is arranged just below the bottom opening of the pulverizing cylinder 2. A sliding plate 34 is slidably arranged at the bottom of the mouth frame 32. The bottom of the discharge funnel 31 is connected to a collecting bag 33 for collecting rosin powder. The collecting bag 33 is placed on the sliding plate 34. A latch 35 is movably arranged on the sliding plate 34. The latch 35 passes through the sliding plate 34 and the mouth frame 32 from top to bottom in sequence.

[0033] When the pulverizer is used to pulverize rosin, the rosin is placed in the feeding barrel 3 and fed into the pulverizing barrel 2 through the feeding pipe 4. When the power motor 6 is working, the rotating shaft 12 is driven to rotate through the pulley assembly 61, and the crushing piece 9 is driven to rotate through the rotating shaft 12. The crushing head of the crushing piece 9 moves circumferentially around the crushing head of the crushing piece 1 8, thereby crushing the solid rosin between the crushing piece 1 8 and the crushing piece 2 9 into powder; the powdered rosin powder falls on the filtering ring 11, and the powder with a diameter smaller than the circular through hole on the filtering ring 11 falls downward to the discharging funnel 3 1, thereby realizing the screening of powdered rosin; when the second rotating shaft 12 rotates, the second rotating shaft 12 drives the turntable 14 to rotate through the reducer 13, and the turntable 14 drives the mouth plate 18 to move up and down through the transmission plate 15. When the mouth plate 18 moves up and down, it drives the push plate 20 to slide up and down along the inner wall of the boost box 16. When the push plate 20 moves up, the one-way valve 24 on the input air pipe 23 at the bottom of the boost box 16 is opened, and the gas enters the boost box 16 through the input air pipe 23 at the bottom of the boost box 16. When the push plate 20 rises, the gas in the boost box 16 is compressed and sent out through the output air pipe 1 21 output, at this time, the one-way valve 122 on the output air pipe 1 21 is opened, and the pressurized gas is sequentially transported to the arc-shaped exhaust frame 28 through the output air pipe 1 21, the three-way pipe 26 and the output main pipe 27 and discharged through the circular holes on the arc-shaped exhaust frame 28, and the discharged gas is blown onto the filter ring 11. Similarly, when the push plate 20 moves downward, the pressurized gas is sequentially transported to the arc-shaped exhaust frame 28 through the output air pipe 2 25, the three-way pipe 26 and the output main pipe 27 and discharged through the circular holes on the arc-shaped exhaust frame 28, thereby achieving the effect of blowing away the rosin powder in the circular holes of the filter ring 11; the mouth plate 18 During the lifting movement, the mouth plate 18 drives the transmission rack 30 to move up and down, and the transmission rack 30 drives the gear 29 meshing therewith to rotate when the transmission rack 30 rises, and the gear 29 rotates half a circle clockwise when the transmission rack 30 moves down, and the gear 29 rotates half a circle counterclockwise, thereby realizing the reciprocating 180-degree rotation movement of the material leveling control unit 5, so as to evenly convey the rosin in the upper part of the inner cavity of the feeding barrel 3 to the feeding pipe 4, thereby realizing the even conveying of the rosin to the crushing barrel 2 for crushing operation, so as to achieve the effect of efficiently crushing the rosin into rosin powder.

[0034] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
