Description

Technical Field

[0001] This utility model relates to the field of pulverizer technology, specifically a multi-functional pulverizer that facilitates screening. Background Technology

[0002] A pulverizer is a machine that crushes large solid raw materials to the required size. In the pharmaceutical production field, the pretreatment of materials such as Chinese medicinal herbs and chemical pharmaceutical raw materials requires a pulverization process to refine the materials to meet the requirements of subsequent extraction, mixing, or formulation processing. However, existing pulverizers still have certain shortcomings, such as: The patent application CN202322414546.9, entitled "A Drug Pulverizer," only has a single pulverizing function and lacks a sieving function. The pulverized material contains particles of different sizes, making it impossible to directly obtain material that meets the particle size requirements. It is necessary to use additional sieving equipment for sieving, which not only increases the production process and equipment costs but also reduces production efficiency, making it difficult to meet actual production needs. In view of this, a multi-functional pulverizer that facilitates sieving is proposed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a multi-functional pulverizer that facilitates screening, thereby solving the problem mentioned in the background art that existing pulverizers have limited functions and cannot perform screening, thus affecting work efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional pulverizer that facilitates screening, including a casing, with support legs provided at the four corners of the bottom surface of the casing; The top of the machine housing is fixedly provided with a feed hopper, and the inside of the machine housing is provided with a rotating rod. Two rotating rods are arranged symmetrically front and back, and the left end of the rotating rod is connected to the left inner wall of the machine housing through a bearing. The rotating rod passes through the right side wall of the machine housing through the bearing. Both rotating rods are provided with crushing rollers, and the two crushing rollers are located inside the machine housing and are compatible with each other. The left inner wall of the chassis is connected to a mounting rod via a bearing, and the mounting rod passes through the right side wall of the chassis via the bearing. A screen frame is fixedly mounted on the surface of the mounting rod, and the screen frame is located below the crushing roller. The rear side wall of the chassis is fixedly provided with a discharge channel, and the top of the discharge channel has an opening located below the rear end of the screen frame, and the bottom of the chassis has a discharge port.

[0005] The above technical solution facilitates the simultaneous crushing and screening of materials, eliminating the need for additional screening equipment, reducing production steps, improving material processing efficiency, and achieving the separation and output of coarse and fine materials.

[0006] As a preferred embodiment of this utility model, a guide hopper is fixedly installed on the inner wall of the casing, and the guide hopper is located below the crushing roller, with the bottom discharge port of the guide hopper located above the front end of the screen frame.

[0007] The above technical solution facilitates guiding the crushed material to the screen frame, ensuring that the material enters the screening process.

[0008] As a preferred embodiment of this utility model, connecting gears are fixedly installed on the surfaces of both rotating rods, and the two connecting gears mesh with each other, with the connecting gears located on the right side of the chassis.

[0009] By adopting the above technical solution, it is easy to drive the two rotating rods to rotate synchronously in opposite directions through the connecting gear transmission, ensuring that the material is uniformly and fully crushed between the two crushing rollers, avoiding incomplete crushing due to inconsistent speed or direction, and improving the crushing effect.

[0010] As a preferred technical solution of this utility model, the right end of the rear rotating rod is keyed to the shaft end of the motor, and the motor is fixedly installed on the right side of the housing. The output shaft of the motor passes through the right side wall of the housing through a bearing, and the housing is fixedly installed on the right side of the chassis.

[0011] The above technical solution facilitates the use of a motor to provide stable power to the rotating rod, ensuring the continuous and efficient operation of the crushing roller.

[0012] As a preferred technical solution of this utility model, a turntable is coaxially fixedly installed on the right end of the front rotating rod, and a drive pin is provided at an eccentric position on the right side of the turntable. A slide plate is provided on the right side of the turntable, and the front end face of the slide plate is longitudinally slidably connected to the front inner wall of the housing. A strip groove is transversely opened on the slide plate, and the drive pin passes through the strip groove. The diameter of the drive pin matches the height of the strip groove.

[0013] The above technical solution facilitates the conversion of the rotational motion of the rotating rod into the longitudinal reciprocating linear motion of the skateboard.

[0014] As a preferred embodiment of this utility model, a rack is fixedly installed on the bottom surface of the slide plate, and the rack meshes with a transmission gear, and the transmission gear is coaxially fixedly installed on the right end of the mounting rod.

[0015] By adopting the above technical solution, it is easy to convert the reciprocating linear motion of the slide into the alternating forward and reverse rotational motion of the mounting rod, thereby driving the screen frame to swing back and forth, and improving the screening efficiency of the screen for materials.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the multi-functional crusher that facilitates screening can directly feed the crushed material into the lower screen frame for screening without the need for additional screening equipment, thus reducing production processes and equipment investment costs. At the same time, it avoids the time loss of material transfer between multiple devices, significantly improves the overall material processing efficiency, and is easy and flexible to operate with strong functionality. 1. The rotating rod is driven by a motor. The two rotating rods rotate synchronously in opposite directions through meshing connecting gears, which drives the crushing roller to crush the material evenly. This avoids incomplete crushing caused by inconsistent speed or direction of rotation, ensures that the particle size of the material is initially uniform, lays the foundation for the subsequent screening process, and guarantees the crushing quality of the output material. 2. The rotation of the rotating rod drives the turntable to rotate. The cooperation between the drive pin and the strip groove causes the slide plate to reciprocate longitudinally, which drives the rack to reciprocate synchronously. Through the transmission gear, the mounting rod and screen frame reciprocate, improving the screening effect of the screen frame on the material. Attached Figure Description

The left end of the rotating rods 3 is connected to the left inner wall of the casing 1 via a bearing, and the rotating rods 3 pass through the right side wall of the casing 1 via a bearing. Each of the two rotating rods 3 is equipped with a crushing roller 4, which is located inside the casing 1 and is compatible with each other. An installation rod 5 is connected to the left inner wall of the casing 1 via a bearing, and the installation rod 5 passes through the right side wall of the casing 1 via a bearing. A screen frame 6 is fixedly installed on the surface of the installation rod 5, and the screen frame 6 is located below the crushing roller 4. A discharge channel 7 is fixedly and through the rear side wall of the casing 1, and the top of the discharge channel 7 has an opening located below the rear end of the screen frame 6. A discharge port is located at the bottom of the casing 1.

[0021] A guide hopper 8 is fixedly installed on the inner wall of the casing 1, and the guide hopper 8 is located below the crushing roller 4, and the bottom discharge port of the guide hopper 8 is located above the front end of the screen frame 6.

[0022] Both rotating rods 3 are fixedly mounted with connecting gears 9, and the two connecting gears 9 mesh with each other. The connecting gears 9 are located on the right side of the chassis 1.

[0023] The right end of the rear rotating rod 3 is keyed to the shaft end of the motor 10, and the motor 10 is fixedly installed on the right side of the housing 11. The output shaft of the motor 10 passes through the right side wall of the housing 11 through the bearing, and the housing 11 is fixedly installed on the right side of the chassis 1.

[0024] A turntable 12 is coaxially fixedly installed on the right end of the front rotating rod 3, and a drive pin 13 is provided at an eccentric position on the right side of the turntable 12. A slide plate 14 is provided on the right side of the turntable 12, and the front end face of the slide plate 14 is longitudinally slidably connected to the front inner wall of the housing 11. A strip groove 15 is transversely opened on the slide plate 14, and the drive pin 13 passes through the strip groove 15. The diameter of the drive pin 13 matches the height of the strip groove 15.

[0025] A rack 16 is fixedly installed on the bottom surface of the slide plate 14, and the rack 16 meshes with the transmission gear 17, and the transmission gear 17 is coaxially fixedly installed on the right end of the mounting rod 5.

[0026] Working principle: When in use, the material is fed into the machine box 1 through the feed hopper 2, and the motor 10 is started. The motor 10 drives the rear rotating rod 3 to rotate. The rear rotating rod 3 meshes with the connecting gear 9 on the front rotating rod 3 through the connecting gear 9 fixed on the surface, so that the front rotating rod 3 rotates synchronously in opposite directions. The two rotating rods 3 drive the crushing rollers 4 on the surface to rotate inside the machine box 1 respectively. The material is crushed and crushed by the two matching crushing rollers 4 and then falls down. The crushed material falls into the guide hopper 8 located below the crushing roller 4, and is guided by the bottom discharge port of the guide hopper 8 to the front end of the screen frame 6 below; Simultaneously, when the front rotating rod 3 rotates, it drives the turntable 12, which is coaxially fixed at the right end, to rotate. The drive pin 13, located at the eccentric position on the right side of the turntable 12, moves within the strip groove 15 of the slide plate 14. Because the front end face of the slide plate 14 is longitudinally connected to the inner wall of the front side of the housing 11, the drive pin 13 drives the slide plate 14 to reciprocate linearly along the longitudinal direction. The rack 16, fixed on the bottom surface of the slide plate 14, moves back and forth with the slide plate 14. The rack 16 meshes with the transmission gear 17, causing the transmission gear 17 to rotate alternately in both directions. This, in turn, causes the mounting rod 5 and the screen frame 6, which is fixed on the surface, to swing back and forth inside the machine box 1. The screen frame 6 screens the falling material. Fine material that meets the particle size requirements falls through the screen frame 6 and is discharged through the discharge port at the bottom of the machine box 1. Coarse material that does not meet the particle size requirements remains in the screen frame 6 and swings with the screen frame 6 to the rear end. It falls into the discharge channel 7 through the top opening of the discharge channel 7 fixed through the rear side wall of the machine box 1 and is finally discharged from the discharge channel 7, completing the crushing and screening of the material.
