[0003] In response, Chinese patent application number CN202120029866.0 discloses a grinding device for drug testing, including a housing and a worktable fixedly mounted on the top of the housing. An inverted U-shaped baffle is provided along the edge of the top of the worktable. Crushing chambers are connected to the housing on both sides of the middle of the top of the worktable. An inlet is opened at the top of each crushing chamber, and a crushing component is located directly below the inlet inside the crushing chamber. This utility model of a grinding device for drug testing utilizes a stepper motor to drive two crushing rollers to rotate relative to each other, enabling the crushing of drugs. Two servo motors drive two cams to rotate, and through the elastic action of a vibration spring, the filter screen is vibrated, thereby sieving the crushed drugs and reducing the possibility of filter clogging. The sieved drug powder falls into two collection boxes for collection, saving time and labor, and preventing the mixing of two drug components, thus improving the accuracy of detection.

[0004] This equipment can crush medicines by setting up crushing rollers. However, in actual use, when the medicines are crushed, due to the squeezing action, some medicines will stick to the part of the crushing rollers that is in direct contact with the medicines and cannot be removed. This results in a decrease in the output of the equipment, and the medicines accumulate more and more on the crushing rollers, which will affect the crushing effect of the crushing rollers on the medicines and reduce the effectiveness of the equipment.

[0005] Therefore, in order to solve the above problems, a grinding device for drug testing is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a grinding device for drug testing, in order to solve the problem mentioned in the background art that the prior art devices can crush drugs by setting up crushing rollers, but in actual use, when the drugs are crushed, due to the squeezing effect, some drugs will stick to the part of the crushing roller that is in direct contact with the drugs and cannot be removed, resulting in a decrease in the output of the device, and the drugs will accumulate more and more on the crushing roller, which will affect the crushing effect of the crushing roller on the drugs and reduce the effectiveness of the device.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a grinding device for pharmaceutical testing, comprising: a housing, a grinding box installed on the top surface of the housing, a discharge trough opened on the front side of the grinding box, and a grinding roller installed on the inner side of the grinding box;

[0008] A cleaning structure is installed at the lower inner side of the grinding box.

[0013] Preferably, the guide plate is installed on the upper side of the grinding roller, and the top surface of the vibrating block is in contact with the inner wall of the active cavity.

[0014] Preferably, the push rod is adapted to the pressure groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by setting a brush cylinder that contacts the bottom surface of the grinding roller and rotates in the opposite direction, the present utility model can brush away the medicines adhering to the surface of the grinding roller when the grinding roller processes medicines, so as to keep the surface of the grinding roller clean, ensure the processing effect of the grinding roller on the medicines, reduce the accumulation of medicines in the device, and improve the user experience of the device.

[0016] 1. This utility model features a cleaning structure. When a dual-head motor is activated, it drives a worm gear to rotate. The worm gear meshes with a worm wheel, and the rotation of the worm gear drives a rotating shaft to rotate via the worm wheel. The rotating shaft then drives a brush cylinder to rotate. The brush cylinder contacts the bottom surface of the grinding roller, and the rotation direction of the brush cylinder is opposite to that of the grinding roller. Therefore, the rotation of the brush cylinder can brush away the medicine on the surface of the grinding roller, keeping the surface of the grinding roller clean, ensuring the processing effect of the grinding roller on the medicine, reducing the accumulation of medicine in the device, and improving the user experience of the device.

[0017] 2. This utility model features a guiding structure. Tablets falling onto the top surface of a guide plate can move along the top surface of the guide plate between two sets of grinding rollers. The grinding rollers grind the medicine. Starting the motor drives a push rod to rotate. As the push rod rotates, its end engages in a pressure groove. With the rotation of the push rod, it presses down on the vibrating block through the pressure groove, causing the vibrating block to descend inside the movable cavity and compress the spring. This causes the top surface of the vibrating block to move away from the inner wall of the movable cavity. With the rotation of the push rod, its end separates from the pressure groove, releasing the downward pressure on the vibrating block. The vibrating block then returns to its original position under the elastic action of the spring. The top surface of the vibrating block impacts the inner wall of the movable cavity, causing the guide plate to vibrate. This guides all the medicine on the top surface of the guide plate between the two sets of grinding rollers. Attached Figure Description

[0028] A material guiding structure 3 is installed on the upper inner side of the grinding box 11. The material guiding structure 3 includes a guide plate 31, which is fixedly installed on the inner wall of the grinding box 11. A movable cavity 32 is opened inside the guide plate 31. A spring 33 is fixedly connected to the inner wall of the movable cavity 32. A vibrating block 34 is fixedly connected to the upper end of the spring 33. A pressure groove 35 is opened on the surface of the vibrating block 34. Motors 36 are fixedly installed on the left and right side walls of the grinding box 11. A push rod 37 is fixedly connected to the output end of the motor 36. The vibrating block 34 can impact the inner wall of the movable cavity 32 upward under the elastic action of the spring 33, causing the guide plate 31 to vibrate. This can guide all the medicine on the top surface of the guide plate 31 to the space between the two sets of grinding rollers 13.

[0029] Furthermore, two sets of rotating shafts 21 are provided, and the two sets of rotating shafts 21 are installed on the lower side of the two sets of grinding rollers 13 respectively. The rotating shafts 21 rotate in the opposite direction to the grinding rollers 13. The two sets of rotating shafts 21 can drive the brush cylinder 22 to rotate on the lower side of the two sets of grinding rollers 13, so as to thoroughly clean the surface of the grinding rollers 13 through the brush cylinder 22.

[0030] Furthermore, the top surface of the brush cylinder 22 contacts the bottom surface of the grinding roller 13. The rotation of the brush cylinder 22 can brush away the medicine on the surface of the grinding roller 13, so as to keep the surface of the grinding roller 13 clean, ensure the processing effect of the grinding roller 13 on the medicine, reduce the accumulation of medicine in the device, and improve the user experience of the device.

[0031] Furthermore, the worm 25 meshes with the worm wheel 23, and the rotation of the worm 25 can drive the rotation shaft 21 to rotate through the worm wheel 23.

[0032] Furthermore, the guide plate 31 is installed on the upper side of the grinding roller 13, and the top surface of the vibrating block 34 is in contact with the inner wall of the movable cavity 32.

As the push rod 37 rotates, it will press down on the vibrating block 34 through the pressure groove 35, causing the vibrating block 34 to descend inside the movable cavity 32 and squeeze the spring 33, so that the top surface of the vibrating block 34 is away from the inner wall of the movable cavity 32. As the push rod 37 rotates, its end will separate from the pressure groove 35, that is, the downward pressure on the vibrating block 34 will be released. The vibrating block 34 can then be reset upward under the elastic action of the spring 33. The top surface of the vibrating block 34 will then hit the inner wall of the movable cavity 32, causing the guide plate 31 to vibrate. This can guide all the medicine on the top surface of the guide plate 31 to the space between the two sets of grinding rollers 13.

[0036] Start the dual-head motor 24, which drives the worm 25 to rotate. The worm 25 meshes with the worm wheel 23. The rotation of the worm 25 drives the rotating shaft 21 to rotate through the worm wheel 23. The rotating shaft 21 then drives the brush cylinder 22 to rotate. The brush cylinder 22 contacts the bottom surface of the grinding roller 13, and the rotation direction of the brush cylinder 22 is opposite to that of the grinding roller 13. Therefore, the rotation of the brush cylinder 22 can brush and remove the medicine on the surface of the grinding roller 13, so as to keep the surface of the grinding roller 13 clean, ensure the processing effect of the grinding roller 13 on the medicine, reduce the accumulation of medicine in the device, and improve the user experience of the device.
