Description
Technical Field
[0001] The utility model relates to the technical field of pill bottling equipment, in particular to an air knife device for blowing off pills. Background Art
[0002] In the fixed quantity packaging of small products such as pills, a pill-loading plate is used for counting. Multiple rows of counting holes are opened on the pill-loading plate. Pills enter the holes from the upper side and are discharged when the pill-loading plate rotates to the bottom with the conveyor belt. However, due to rolling friction during the process of loading the pills into the pill-loading plate, the pills themselves generate friction static electricity. Due to static electricity, the pills are adsorbed on the pill-loading plate and cannot fall naturally under the action of gravity. This makes it inconvenient to count and measure the pills during loading. Therefore, it is necessary to use external equipment to remove the pills from the pill-loading plate to prevent the pills from being adsorbed on the pill-loading plate.
[0003] Therefore, a device for dropping pills is needed to solve the above problems. Utility Model Content
[0004] In view of the above problems, the present invention is proposed to provide a pill blowing air knife device that overcomes the above problems or at least partially solves the above problems, which can solve the problem of pills being adsorbed on the pill loading plate due to static electricity, and achieve the effect of pills falling from the pill loading plate.
[0005] Specifically, the utility model provides an air knife device for blowing off pills, comprising:
[0006] The blade body includes a positioning plate and a wind plate, an air cavity is set between the positioning plate and the wind plate, an air outlet is set on the lower side of the wind cavity, a guide protrusion is set in the wind cavity, and the cross-section of the guide protrusion is triangular. A guide plate is set on the lower side of the positioning plate, and the inner wall contour of the guide plate and the lower side contour of the guide protrusion are arranged parallel to each other;
[0007] An air pipe joint is provided on the upper side of the air plate, and the air pipe joint connects the ventilation cavity with the outside world.
[0008] The vents are formed between the vents and the air intake, and the vents are connected to the outside of the vents by the guide protrusions. The vents are then passed through the vents to the outside of the vents, and the airflow is directed to the vents at the vents.
[0009] Optionally, positioning grooves are provided on the side walls of the positioning plate, and multiple groups of positioning grooves are provided along the length direction of the positioning plate, and threads are provided in the positioning grooves.
[0010] By opening a positioning groove on the side wall of the positioning plate and setting a thread in the positioning groove, the positioning plate can be installed in the working space using the positioning groove. Multiple groups of positioning grooves can ensure the stability of the positioning plate and thus ensure the stability of the entire air knife device.
[0011] Optionally, the turning points on the inner wall of the air cavity are all rounded.
[0012] In order to better ensure the smoothness of the airflow in the air cavity, the turning points on the inner wall of the air cavity are rounded to improve the integration of the airflow and avoid turbulence in the air cavity.
[0013] Optionally, arc-shaped guide grooves are provided on the positioning plates and the wind plates on both sides of the air outlet, and the arc-shaped guide grooves on the positioning plates and the wind plates are provided corresponding to each other.
[0014] By arranging the arc guide grooves on the positioning plate and the wind plate in correspondence with each other, and utilizing the opposing arc guide grooves, the direction of the airflow output is guided, so that the airflow is more targeted toward the medicine holes on the medicine loading plate, ensuring the stability of blowing the pills off.
[0015] Optionally, the guide plate is inclined toward a side close to the wind plate, and the height of the lower side of the wind plate is lower than the height of the lower side of the guide plate.
[0016] Tilting the guide plate toward the side close to the wind plate can reduce the occupancy rate of the positioning plate on the working space and improve the practicality of the equipment. Setting the lower side height of the wind plate lower than the lower side height of the guide plate can provide final guidance for the direction of the airflow, so that the airflow at the air outlet can flow specifically into the medicine holes of the medicine loading plate.
[0017] Optionally, the air pipe joints are equally divided into multiple groups along the length direction of the air plate.
[0018] In order to improve the uniformity of the air flow in the air cavity and to produce sufficient impact effect when the air flow is output at the air outlet, the air pipe joints are equally divided into multiple groups along the length of the air plate to increase the air intake of the air cavity.
[0019] Optionally, positioning bolt holes are provided at both ends of the positioning plate.
[0020] The provision of the positioning bolt holes can facilitate the fixing of both ends of the positioning plate and improve the stability of the air knife.
[0021] In the technical solution of the present invention, since a guide protrusion is provided in the wind cavity, the guide protrusion is used to guide the airflow input into the wind cavity at the trachea joint, firstly concentratedly guided to the opposite side of the guide protrusion, and then the inner wall contour of the guide plate and the lower side contour of the guide protrusion are arranged parallel to each other, so that the airflow guided to the opposite side of the guide protrusion can be evenly transported to the air outlet along the inner wall of the guide plate and the lower side of the guide protrusion.
[0022] Furthermore, in the technical solution of the present invention, in order to better ensure the smoothness of the airflow in the air cavity, the turning points on the inner wall of the air cavity are rounded to improve the integration of the airflow and avoid turbulence in the air cavity.

An air pipe joint 6 is arranged on the upper side of the air plate 2, and the air pipe joint 6 connects the ventilation cavity 3 with the outside world.
[0037] By setting an air cavity 3 between the positioning plate 1 and the air plate 2, and setting an air pipe joint 6 on the upper side of the air plate 2 to connect the ventilation cavity 3 with the outside, the sealing stability of the air cavity 3 can be ensured, and by setting a guide protrusion 4 in the air cavity 3, the airflow input into the air cavity 3 at the air pipe joint 6 at the guide protrusion 4 is first concentrated and guided to the opposite side of the guide protrusion 4, and then the inner wall contour of the guide plate 5 and the lower side contour of the guide protrusion 4 are arranged in parallel with each other, so that the airflow guided to the opposite side of the guide protrusion 4 can be evenly transported to the air outlet along the inner wall of the guide plate 5 and the lower side of the guide protrusion 4, thereby improving the air outlet. The airflow stability is improved, and the width dimension at the air outlet is smaller than the spacing dimension between the inner wall of the guide plate 5 and the lower side of the guide protrusion 4, which can increase the wind speed at the air outlet, thereby better blowing off the pills on the medicine-loading plate 10. A medicine hole 11 is provided in the medicine-loading plate 10, which passes through the medicine-loading plate 10. A limiting neck with a diameter smaller than that of the pill is provided in the medicine hole 11.
