[0029] In order to make the person skilled in the art better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0030] Currently, in the solid preparation automatic production line of the pharmaceutical, food and other industries, the electronic particle counter, as the key equipment to realize accurate counting and sub-packaging of materials, needs to work with upstream and downstream conveying equipment to meet the continuous production requirements.

[0031] Among them, the elevator for material conveying (a separate device independent of the electronic particle counter) is usually arranged at the feeding end of the electronic particle counter, responsible for lifting and conveying the materials such as tablets to be counted into the hopper of the electronic particle counter. The two are connected through the feeding port of the hopper, and the hopper is usually fixed rigidly on the rack of the electronic particle counter.

[0032] However, in the long-term operation process, as shown in Figure 1 When the discharge end of the elevator deviates due to vibration, installation deviation or component wear, it will repeatedly collide with the hopper 13 of the electronic particle counter 1. This collision will cause the hopper 13 to deform gradually. On the one hand, the gap between the hopper 13 and the conveying belt 12 on the rack 11 will increase unevenly due to deformation, causing tablets to leak out of the gap, polluting the conveying belt and the surrounding environment, and the leaked tablets may be squeezed and broken by the two, affecting product quality. On the other hand, the deformed hopper 13 and the conveying belt 12 locally overfit, which will increase the frictional resistance and generate heat, easily causing the driving motor of the conveying belt 12 to overheat and burn out. Meanwhile, the generated rubber debris will pollute the medicine, and in severe cases, the machine needs to be stopped for maintenance, affecting the continuity of production.

[0033] The electronic particle counter and the medicine production line provided by the embodiments of the present application can solve the technical problems that in the long-term operation process of the traditional electronic particle counter, the elevator collides with the hopper, causing the hopper to deform, the gap between the hopper and the conveying belt increases due to deformation, tablets leak out and pollute the conveying belt, and the tablets may be broken; the uneven gap causes the local extrusion of the belt, the friction generates heat, easily causing the motor to burn out, and the generated rubber debris pollutes the medicine.

[0034] As shown in Figure 2 In a first aspect, the embodiments of the present application provide an electronic particle counter, which comprises: a rack 11, the rack 11 is installed with a conveying belt 12 and a hopper 13, and the hopper 13 is located above the conveying belt 12; a lifting and buffering mechanism 2, which is arranged between the rack 11 and the hopper 13, and is used to lift and support the hopper 13, so that the hopper 13 has a gap with the conveying belt 12; two pressing strips 4, the length direction of the pressing strip 4 is consistent with the length direction of the conveying belt 12, and a plurality of adjusting gaps 41 are arranged on one side wall of the pressing strip 4 along the length direction of the pressing strip 4, and the two pressing strips 4 are distributed on the opposite two outer side walls of the hopper 13 and fixed on the corresponding outer side walls.

[0035] In this embodiment, the lifting and buffering mechanism 2 is arranged between the rack 11 and the hopper 13, and the hopper 13 is kept at a distance from the conveying belt 12 by lifting and supporting the hopper 13. This structure avoids direct contact between the hopper 13 and the conveying belt 12, reduces wear caused by long-term friction, and reduces the impact force caused by the collision between the elevator and the hopper 13 by using the buffering characteristics, thereby reducing the risk of deformation of the hopper 13. The two pressing strips 4 are distributed on the opposite outer side walls of the hopper 13 along the length direction of the conveying belt 12. The plurality of adjusting gaps 41 on the side wall can realize fine adjustment of the position of the pressing strip 4. By restraining the outer side wall of the hopper 13 through the pressing strip 4, the local deformation of the hopper 13 caused by the impact can be compensated, the uniformity of the gap between the hopper 13 and the conveying belt 12 is improved, the leakage of the tablets is avoided, the conveying belt 12 is prevented from being contaminated by the leakage of the tablets, the problem of the tablets being jammed and broken is avoided, and the local extrusion of the hopper 13 to the conveying belt 12 caused by uneven gap is prevented.

[0036] In combination with the first aspect, in an embodiment, the electronic particle counter further comprises a plurality of bolts 5, the bolts 5 penetrating the adjusting gaps 41 and being threadedly connected to the outer side wall of the hopper 13 to press the pressing strip 4 to the outer side wall of the hopper 13. Figure 2 Figure 3 In combination with the first aspect, in an embodiment, the electronic particle counter further comprises a plurality of bolts 5, the bolts 5 penetrating the adjusting gaps 41 and being threadedly connected to the outer side wall of the hopper 13 to press the pressing strip 4 to the outer side wall of the hopper 13.

[0037] In this embodiment, the plurality of bolts 5 penetrate the adjusting gaps 41 of the pressing strip 4 and are threadedly connected to the outer side wall of the hopper 13 to press the pressing strip 4 to the outer side wall of the hopper 13. When the hopper 13 is deformed due to impact, the position adjustment of the pressing strip 4 is realized through the cooperation of the bolt 5 and the adjusting gap 41. If the gap between the local (such as the right side) of the hopper 13 and the conveying belt 12 is too large, the bolt 5 at the corresponding position is loosened, the pressing strip 4 is slid downward along the length direction (perpendicular to the wall of the hopper 13) of the adjusting gap 41 until the inner side of the pressing strip 4 is tightly attached to the outer wall of the deformed area of the hopper 13, and then the bolt 5 is tightened to fix the pressing strip 4. The gap between the area and the conveying belt 12 is reduced through the restraining action of the pressing strip 4 to avoid the leakage of the tablets. If the hopper 13 has a local (such as the left side) protrusion, the pressing strip 4 is bent by using the adjusting gap 41 of the pressing strip 4, the bolt 5 of the corresponding protruding area is adjusted, and the pressing strip 4 deforms along with the surface curve of the hopper 13 to improve the uneven gap. The irregular protrusions of the hopper 13 are compensated by the adaptive deformation of the pressing strip 4 to improve the uneven gap caused by the protrusions and prevent the local extrusion of the hopper 13 to the conveying belt 12 to generate heat by friction and pollution of rubber debris. The cooperation of the bolt 5 and the adjusting gap 41 makes the position adjustment of the pressing strip 4 more stable and controllable, and the problems of leakage, friction and pollution are effectively solved through the targeted pressing of different deformation areas.

[0038] In combination with the first aspect, in an embodiment, the side of the pressing strip 4 facing the outer side wall of the hopper 13 is provided with a flexible pad.

[0039] ​In the embodiment, the flexible pad one is arranged on the side of the pressing strip 4 facing the outer side wall of the hopper 13, and is filled between the pressing strip 4 and the outer side wall of the hopper 13. When the bolt 5 penetrates the adjusting gap 41 of the pressing strip 4 and is screwed to the outer side wall of the hopper 13, the flexible pad one is elastically deformed by being pressed, fills the unevenness of the surface of the hopper 13 caused by impact, and enhances the fit between the pressing strip 4 and the hopper 13. The elastic buffering effect of the flexible pad one disperses the pre-tightening force of the bolt 5, avoids stress concentration caused by the pressing strip 4 to the hopper 13, and prevents the hopper 13 from being further deformed. When the side wall of the hopper 13 is locally concave or convex, the flexible pad one is adaptively deformed with the adjustment of the pressing strip 4, maintains the close contact with the outer wall of the hopper 13, ensures the restraining effect of the pressing strip 4 on the deformed area of the hopper 13, and improves the compensation ability and sealing effect of the pressing strip 4 on the deformation of the hopper 13, thereby prolonging the service life of the equipment and ensuring the cleanliness of the medicine production.

[0040] In combination with the first aspect, in an implementation mode, the flexible pad one comprises a silica gel pad, and the thickness of the silica gel pad is a, and 1mm≤a≤3mm.

[0041] In the embodiment, the flexible pad one is a silica gel pad, and the thickness a satisfies 1mm≤a≤3mm. The elastic modulus of the silica gel pad is matched with the metal material of the pressing strip 4 and the hopper 13. When the bolt 5 is pre-tightened, the thickness of 1-3mm enables the silica gel pad to have sufficient elastic deformation to fill the unevenness of the surface of the hopper 13, and also maintains the structural strength to avoid failure caused by excessive compression. The chemical stability of the silica gel pad prevents it from reacting when it is in contact with the medicine, meets the hygiene requirements of medicine production, effectively buffers the pressure of the pressing strip 4 on the hopper 13, and reduces stress concentration. When the pressing strip 4 is bent and adjusted due to the deformation of the hopper 13, the silica gel pad with the thickness in the range can change with the shape and maintain the sealing performance, thereby preventing the tablets from leaking out of the gap. In addition, the silica gel pad with the appropriate thickness can absorb the vibration energy in the operation of the equipment, reduce the friction noise and wear between the pressing strip 4 and the hopper 13, and optimize the sealing, buffering and adaptive deformation ability of the silica gel pad within the limited thickness range, thereby improving the stability of the equipment and the quality of medicine production.

[0042] In combination with the first aspect, in an implementation mode, as shown in Figure 2 The lifting and buffering mechanism 2 comprises four support frames 22, the bottom end of each support frame 22 is fixed with an elastic piece 21, the elastic piece 21 is fixed to the rack 11, and the top end of each support frame 22 is provided with a groove. The opposite two outer side walls of the hopper 13 are each fixed with four convex columns 3, and the convex columns 3 are arranged in the corresponding grooves.

[0043] In this embodiment, the lifting and buffering of the hopper 13 is achieved by four support frames 22 and elastic members 21. The elastic members 21 are fixed to the rack 11 and support the support frames 22. The elastic force generated by the initial compression state of the elastic members 21 lifts the entire hopper 13, so that the hopper 13 maintains a 2-3mm spacing with the conveying belt 12, avoiding long-term contact and friction. The convex column 3 on the outer sidewall of the hopper 13 is embedded in the groove at the top end of the support frame 22. The limiting effect of the groove on the convex column 3 restricts the horizontal displacement of the hopper 13, ensuring the stability of the hopper 13 during operation. When the elevator collides with the hopper 13, the elastic members 21 absorb the impact energy through the compression-rebound process, reducing the vibration amplitude of the hopper 13 and the risk of deformation. The elastic modulus of the elastic members 21 is matched with the weight of the hopper 13, so that the hopper 13 maintains a stable height during normal operation and can quickly return to the initial position after being impacted. The lifting and buffering mechanism 2 effectively protects the hopper 13 and the conveying belt 12, prolongs the service life of the equipment, and improves the operation reliability.

[0044] In combination with the first aspect, in an implementation manner, the elastic member 21 comprises a spring or a spring washer.

[0045] In this embodiment, the elastic member 21 of the lifting and buffering mechanism 2 adopts a spring or a spring washer. The spring or spring washer has elastic deformation characteristics. It is fixed between the rack 11 and the support frame 22. The pre-compression in the initial state generates an upward elastic force, which lifts the hopper 13 to maintain a predetermined spacing with the conveying belt 12, avoiding direct contact between the two. When the elevator collides with the hopper 13, the spring or spring washer absorbs the impact energy by further compression, buffers the impact force on the hopper 13, and reduces the deformation of the hopper 13 caused by rigid impact. The continuous elastic deformation of the spring or the layered elastic compensation of the spring washer can adapt to impacts of different intensity, ensuring that the hopper 13 can quickly reset after impact and maintain the stability of the spacing with the conveying belt 12. At the same time, the spring or spring washer has a simple structure and low cost, and is reliably connected with the support frame 22 and the rack 11, which can withstand the weight and repeated impacts of the hopper 13 for a long time, ensuring the continuous and effective operation of the lifting and buffering mechanism 2.

[0046] In combination with the first aspect, in an implementation manner, the inner diameter of the groove gradually decreases in the direction from the groove opening to the groove bottom.

[0047] In this embodiment, the inner diameter of the groove gradually changes to form a guide slope. When the convex column 3 of the hopper 13 is assembled into the groove, the larger inner diameter of the slot facilitates the quick alignment of the convex column 3 with the slot. As the assembly proceeds, the gradually decreasing inner diameter guides the convex column 3 to slide into the pre-set position at the bottom of the slot, reducing the collision and jamming of the convex column 3 with the edge of the groove during assembly, and improving the assembly efficiency of the hopper 13 and the support frame 22. At the same time, the guiding feature ensures the consistency of the fitting position of the convex column 3 and the groove, avoiding the tilting of the hopper 13 due to assembly deviation, and thus ensuring the uniformity of the initial gap between the hopper 13 and the conveyor belt 12. Through the above design, the gradually changing inner diameter of the groove focuses on optimizing the assembly guide, improving the installation convenience and initial positioning accuracy of the equipment.

[0048] In combination with the first aspect, in an implementation mode, a flexible pad two is arranged inside the groove.

[0049] In this embodiment, the flexible pad two is filled between the inner wall of the groove and the convex column 3. When the hopper 13 vibrates due to impact, the elastic deformation of the flexible pad two absorbs and disperses the vibration energy, reducing the rigid collision between the convex column 3 and the groove, and reducing the shaking amplitude of the hopper 13. The existence of the flexible pad two compensates for the assembly gap between the groove and the convex column 3, enhances the close contact between the two, and makes the hopper 13 maintain a stable position during operation, avoiding deviation or abnormal noise caused by the gap. When the equipment starts or stops or the load changes, the buffering effect of the flexible pad two reduces the impact force of the convex column 3 on the groove, prolonging the service life of the groove and the convex column 3.

[0050] In combination with the first aspect, in an implementation mode, the material of the pressing strip 4 is stainless steel.

[0051] In this embodiment, the pressing strip 4 is made of stainless steel. Stainless steel has high structural strength and rigidity. When the pressing strip 4 is fixed to the outer side wall of the hopper 13 by the bolt 5 and deforms to adjust the bending, it can maintain its own structural stability, avoiding adjustment failure caused by excessive deformation of the pressing strip 4 itself. At the same time, the corrosion resistance and chemical stability of stainless steel meet the sanitary requirements of pharmaceutical production, which can prevent the pressing strip 4 from rusting due to long-term contact with drugs or environmental moisture, avoiding the pollution of rust debris to drugs. In addition, the smooth surface of stainless steel has a small friction coefficient with the outer side wall of the hopper 13 and the inner silicone pad, which can reduce the wear of the silicone pad during the sliding adjustment of the pressing strip 4, prolonging the service life of the flexible pad one.

[0052] In summary, after long-term operation of the electronic particle counter 1, the impact of the elevator on the hopper 13 causes the hopper 13 to deform, leading to the following problems: the gap between the hopper 13 and the conveyor belt 12 increases due to deformation, causing tablets to leak out and contaminate the conveyor belt 12, and possibly breaking the tablets; uneven gaps cause the hopper 13 to locally squeeze the conveyor belt 12, generating heat and easily burning the motor, and producing rubber debris that contaminates the drugs.

[0053] Wherein, the opposite two outer walls of the hopper 13 are equipped with 304 stainless steel strips 4, which are arranged along the outer wall of the hopper 13 and have a thickness matching the hopper wall. The strips 4 are provided with adjusting gaps 41, and are fixed to the hopper 13 by M4 bolts 5 which can slide up and down in the adjusting gaps 41 to realize fine adjustment of the position of the strips 4. The inner side of the strips 4 is pasted with food-grade silica gel pads with a thickness of about 1-3 mm to fill the small gap between the strips 4 and the hopper 13.

[0054] Wherein, the hopper 13 is installed above the conveying belt 12 by four support frames 22 with elastic members 21, the bottom of the support frame 22 is connected with the rack 11 to lift the whole hopper 13, so that the hopper 13 and the conveying belt 12 are kept in a non-contact state (the initial gap can be adjusted by the pre-tightening force of the elastic members 21).

[0055] Wherein, the strips 4 can be bent and adjusted, and the middle part is provided with adjusting gaps 41. When the hopper 13 is locally depressed or protruded due to impact, the corresponding position of the bolt can be tightened to make the strip 4 bend and fit the deformed area of the hopper, so as to realize local precise adjustment of the gap.

[0056] Wherein, the elastic members 21 at the bottom of the support frame 22 lift the whole hopper 13 to a height of 2-3 mm from the belt 2 (non-contact state) to avoid damage to the belt caused by long-term friction. Loosen the bolt 5, and according to the deformation of the hopper 13 (such as the right side gap being too large), slide the corresponding position of the strip 4 down to adjust the adjusting range of the gap 41, and reduce the gap; for the local protruding area, the middle part of the strip is bent (the distance of the adjusting gap 41 is utilized) to make the strip 4 adapt to the surface curve of the bottom of the hopper 13, so as to improve the uneven gap.

[0057] Wherein, the silica gel pad forms a flexible seal after being pressed by the strip 4 to prevent tablets from leaking out; the hopper 13 and the conveying belt 12 are designed in a non-contact manner, and only the gap is adjusted by the strip 4 to avoid the wear and tear problem of the traditional direct extrusion of the conveying belt 12.

[0058] Wherein, through the structure of "overall lifting + local fine adjustment", the overall deformation influence is eliminated by the elastic members 21, and then the local gap is precisely controlled by the strip 4 and the adjusting gap 41 to break through the limitations of the traditional single adjustment mode; the combination of the silica gel pad and the non-contact belt layout not only solves the problem of material leakage, but also avoids mechanical friction damage and prolongs the service life of the equipment; at the same time, the strip 4 can bend with the irregular deformation of the hopper 13, and the deformation caused by impact is compensated by the mechanical structure, so that the whole part does not need to be replaced, and the maintenance cost is reduced.

[0059] The risk of tablet leakage and pollution is reduced, and the hygiene standard of drug production is improved; the direct friction between the hopper 13 and the conveying belt 12 is avoided, and the risk of motor overload and burning is reduced; the strip 4 can quickly adjust the gap, shorten the equipment maintenance time, and improve the production efficiency.
