Description

Technical Field

[0001] The utility model relates to the technical field of pill counters, in particular to an eccentric vibration device for a pill counter. Background Art

[0002] A pill counter is a machine applicable to industries such as pharmaceuticals, hospitals, and food, and is used for counting medicines or foods such as capsules, tablets, and granules. Among them, there are many types of capsules. After the capsules are produced, they need to be bottled. However, in the actual production process, due to large static electricity, the pills of the pill counter are adsorbed on the upper wall of the pill holes or suspended in the holes, and do not fall down to block the light of the opposed infrared sensor. The PLC thinks that there is a lack of pills, resulting in a large number of medicine bottles being rejected, which affects the production. Since the medicine plate moves relatively fast during the operation of the pill counter, the use requirements cannot be met by the method of manual auxiliary detection.

[0003] Therefore, there is an urgent need for a technical solution to solve the above problems. Summary of the Utility Model

[0004] In view of the above problems, the present utility model is proposed to provide a pill counter in which pills are adsorbed on the upper wall of the pill holes or suspended in the holes due to large static electricity, and do not fall down to block the light of the opposed infrared sensor, which can solve the problem that the pills are adsorbed on the upper wall of the pill holes or suspended in the holes, and achieve that the pills can stably fall into the pill holes.

[0005] Specifically, the present utility model provides an eccentric vibration device for a pill counter, including a pill plate and a pill counter, and further including:

[0006] A vibration bracket, which is arranged on the pill counter to support a vibration component;

[0007] A vibration component, which includes a vibration plate suspended and assembled on the vibration bracket. An eccentric fan is arranged on the upper side of the vibration plate. A bolt is installed on one of the fan blades of the eccentric fan to make the eccentric fan unbalanced during operation to achieve a vibration effect. The lower side of the vibration plate contacts the pill plate, and the vibration plate transmits the vibration generated by the eccentric fan to the pill plate;

[0008] A vibration limiting plate, which is arranged on the pill counter and below the vibration plate to limit the vibration amplitude of the vibration plate.

[0009] When the pill plate runs with the equipment on the pill machine, the pills normally fall into the pill holes. However, due to the generation of a certain amount of static electricity during the pill conveying process, when the static electricity is too large, some pills will be adsorbed on the upper wall of the pill hole or suspended in the hole, which will cause the subsequent PLC to think that there is a lack of pills and result in the rejection of many medicine bottles. To avoid this situation, a vibration bracket is set on the conveying path of the pill plate, and a vibration plate is set on the vibration bracket. The vibration plate is used to vibrate the pill plate, so that the pills adsorbed on the upper wall of the pill hole or suspended in the hole can fall into the pill hole, thus ensuring the stability of the pill plate in conveying pills.

[0010] By setting an eccentric fan on the upper side of the vibration plate and installing a bolt on one of the fan blades of the eccentric fan, when the eccentric fan starts to operate, due to the existence of the bolt, the fan blade will be unbalanced during the movement, thus driving the vibration plate to vibrate. The lower side of the vibration plate contacts the pill plate and transmits the vibration generated by the eccentric fan to the pill plate, so as to achieve the vibration effect on the pill plate.

[0011] To prevent the vibration amplitude of the vibration plate from being too large during the vibration with the eccentric fan, a vibration limit plate is set to limit the vibration amplitude of the vibration plate.

[0012] Optionally, a fan cover is provided on the vibration plate, the eccentric fan is arranged in the fan cover, and the fan cover is fixed to the vibration plate by bolts.

[0013] To facilitate the loading and unloading of the eccentric fan on the vibration plate, a fan cover is set on the vibration plate, and the fan cover is used to disassemble with the vibration plate.

[0014] Optionally, a protective net is detachably connected to the upper side of the fan cover to prevent sundries from falling and damaging the fan blades.

[0015] The setting of the protective net can, on the one hand, prevent sundries from falling into the working surface of the fan blades, resulting in damage to the fan blades, and on the other hand, it is also for safety considerations to avoid harm to the staff during the operation of the eccentric fan.

[0016] Optionally, two groups of V-shaped positioning frames are provided on the protective net, and the open ends of the two groups of V-shaped positioning frames are connected to the fan cover to fix the protective net to the fan cover.

[0017] To facilitate the maintenance of the fan blades during actual use, the protective net is fixed to the fan cover by setting two groups of V-shaped positioning frames. When the fan blades need to be maintained, only the two groups of V-shaped positioning frames need to be disassembled, and the fan blades can be exposed for maintenance.

[0018] Optionally, a gap is provided between the vibration plate and the lower part of the vibration limit plate to prevent the vibration amplitude of the vibration plate from being too large.

[0019] A gap is provided between the vibration plate and the lower part of the vibration limiting plate to provide a vibration space for the vibration of the vibration plate, and at the same time, it will not cause the amplitude of the vibration plate to be too large, resulting in damage to the medicine pellet plate.

[0020] Optionally, the vibration plate is a curved plexiglass plate.

[0021] The plexiglass plate is light in weight, and while achieving the vibration effect, it will not cause damage to the medicine pellet plate.

[0022] Optionally, a vibration limiting sleeve is provided at the front end of the vibration plate, and the vibration limiting sleeve is buckled on the vibration bracket.

[0023] In order to facilitate the assembly relationship between the vibration plate and the vibration bracket, by providing a vibration limiting sleeve at the front end of the vibration plate and directly buckling the vibration limiting sleeve on the vibration bracket, it is more convenient to use.

[0024] Optionally, a vibration limiting groove is provided on the vibration bracket, and the vibration limiting sleeve is buckled in the vibration limiting groove.

[0025] The vibration limiting groove can provide an installation space for the installation of the vibration limiting sleeve, and can limit the displacement of the vibration limiting sleeve in the axial direction of the vibration bracket, ensuring the stability of the vibration plate during use.

[0026] Optionally, the vibration limiting sleeve is a U-shaped sleeve, and there is a clearance fit between the vibration limiting sleeve and the vibration bracket to enable the vibration plate to vibrate with the eccentric fan.

[0027] Making the vibration limiting sleeve a U-shaped sleeve can be more conveniently buckled on the vibration bracket, and the clearance fit between the vibration limiting sleeve and the vibration bracket can provide an amplitude space for the vibration of the vibration plate, enabling the vibration plate to vibrate with the eccentric fan.

[0028] Optionally, multiple groups of vibration plates are provided on the vibration bracket.

[0029] According to actual usage needs, in the case of a relatively long medicine pellet plate, multiple groups of vibration plates can be set to achieve a stable vibration effect.

[0030] In the technical solution of the present utility model, since an eccentric fan is provided on the upper side of the vibration plate and a bolt is installed on one of the fan blades of the eccentric fan, when the eccentric fan starts to operate, due to the presence of the bolt, the fan blade will be unbalanced during the movement process, thereby driving the vibration plate to vibrate. The lower side of the vibration plate contacts the medicine pellet plate and transmits the vibration generated by the eccentric fan to the medicine pellet plate, thereby achieving the vibration effect on the medicine pellet plate, enabling the pills adsorbed on the upper wall of the pill holes or suspended in the holes to fall into the medicine pellet holes, thereby ensuring the stability of the medicine pellet plate for transporting pills.

[0031] Further, in the technical solution of the present utility model, a protective net is detachably connected to the upper side of the fan cover. The protective net can, on the one hand, prevent sundries from falling into the working surface of the fan blades, resulting in damage to the fan blades, and on the other hand, for safety reasons, avoid causing harm to the staff during the operation of the eccentric fan.
