[0040] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0041] Please refer to Figures 1 to 3 The specific implementation of the utility model relates to a device for detecting a middle-packaged medicine strip 11, comprising:

[0042] Rack 1;

[0043] A conveyor belt 2, wherein the conveyor belt 2 is connected to the frame 1, and the conveying direction of the conveyor belt 2 is an X direction;

[0044] A lateral limiting mechanism, the lateral limiting mechanism comprises a first side plate 31 symmetrically arranged on the Y-direction side of the conveyor belt 2 and a second side plate 32 on the opposite side of the Y-direction, the first side plate 31 being perpendicular to the Y-direction and parallel to the second side plate 32;

[0045] A pressing assembly 4, the pressing assembly 4 comprising a pressing plate 41 and a first telescopic cylinder 42, the pressing plate 41 being located above the middle of the conveyor belt 2, and the pressing plate 41 being connected to the frame 1 in a liftable manner through the first telescopic cylinder 42;

[0046] A first rotary encoder 51, which is connected to the frame 1, is located on the Y-direction side of the lower pressing plate 41, and is located on the Y-direction side of the first side plate 31; the axis of the rotating shaft of the first rotary encoder 51 is in a vertical direction, the rotating shaft of the first rotary encoder 51 is connected to a first lever 52 which is perpendicular to the rotating shaft thereof, and the first side plate 31 is provided with an avoidance hole 311 at a position where the lower pressing plate 41 is located, and in a free state, the first lever 52 passes through the avoidance hole 311 and extends to the inner side of the first side plate 31;

[0047] A second rotary encoder 61, which is connected to the frame 1, and is located on the Y-direction side of the lower pressing plate 41. The second rotary encoder 61 is located on the Y-direction side of the first side plate 31. The second rotary encoder 61 has a rotating shaft connected to a second lever 62 perpendicular to the rotating shaft. In a free state, the second lever 62 passes through the avoidance hole 311 and extends to the inner side of the first side plate 31. The first lever 52 and the second lever 62 are staggered in an upper and lower manner.

[0048] A screw guide rail assembly 7, wherein the screw guide rail assembly 7 is arranged above the conveyor belt 2 along the Y direction, the screw guide rail assembly 7 is located on the X direction side of the pressing assembly 4, and both ends of the screw guide rail assembly 7 extend to the outside of the conveyor belt 2 respectively;

[0049] A nut slider 81, wherein the nut slider 81 is slidably connected to the screw guide rail assembly 7, and a mounting plate 82 is connected to the lower part of the nut slider 81, and a first metal sensor 83 and a second metal sensor 84 are respectively arranged on the X-direction reverse side of the mounting plate 82, and a third metal sensor 85 and a fourth metal sensor 86 are respectively arranged on the X-direction side of the mounting plate 82, which are distributed up and down and face the X-direction;

[0050] The detection method of the device for detecting the middle-packaged medicine strip 11 comprises the following steps:

[0051] Adjust the spacing between the first side plate 31 and the second side plate 32 to be the spacing of the width of 10 medicine strips 11;

[0052] The conveyor belt 2 is conveyed in the X direction in steps. When the conveyor belt 2 is in a stopped state, 20 medicine strips 11 are placed at the beginning of the conveyor belt 2 with their axial direction facing the X direction and both ends flush, so that the medicine strips 11 are distributed in two layers, with 10 strips in each layer.

[0053] When the conveyor belt 2 moves step by step until 20 medicine strips 11 move to the bottom of the lower pressing plate 41, the first telescopic cylinder 42 is controlled to drive the lower pressing plate 41 to press down, so that the distance between the lower end of the lower pressing plate 41 and the belt surface of the conveyor belt 2 is less than twice the diameter of the medicine strip 11 by 1-10 mm, and then the first telescopic cylinder 42 is controlled to drive the lower pressing plate 41 to move upward to separate from the medicine strip 11;

[0054] The readings of the first rotary encoder 51 and the second rotary encoder 61 are read, and at the same time, the screw guide assembly 7 is controlled to drive the nut slider 81 to move along the Y direction or the reverse direction of the Y direction, so that the first metal sensor 83 senses the number of metal buckles 111 at the X-direction end of the upper medicine strip 11, the second metal sensor 84 senses the number of metal buckles 111 at the X-direction end of the lower medicine strip 11, the third metal sensor 85 senses the number of metal buckles 111 at the reverse end of the X direction of the previous batch of upper medicine strips 11, and the fourth metal sensor 86 senses the number of metal buckles 111 at the reverse end of the X direction of the previous batch of lower medicine strips 11, until the nut slider 81 moves to the outside of the first side plate 31 or the second side plate 32;

[0055] The conveyor belt 2 continues to convey in the X direction, and the above steps are repeated.

[0056] In the above embodiment, when the two layers of arranged medicine strips 11 are stepped along the conveyor belt 2 to the lower end of the lower pressing plate 41, the medicine strips 11 are squeezed by a certain pressure through the downward pressure of the lower pressing plate 41. At this time, if the metal buckles 111 at both ends of the medicine strips 11 are not fastened, the emulsion explosive will squeeze the metal buckles 111 under the action of pressure, so that the metal buckles 111 are separated from the medicine strips 11, thereby loosening the medicine strips 11; after the lower pressing plate 41 is separated from the medicine strips 11, the compactness of the filling of the medicine strips 11 or whether the quantity is insufficient is judged by the readings of the first rotary encoder 51 and the second rotary encoder 61 on the side. Since the first lever 52 and the second lever 62 are both extended to the inside of the first side plate 31 in the free state, when the conveyor belt 2 drives the medicine strips 11 to pass, the first lever 52 will be blocked by the medicine strips 11 of the upper layer and rotate together with the first rotary encoder 51, and the second lever 62 will be blocked by the medicine strips 11 of the lower layer and rotate together with the second rotary encoder 51. The rotary encoder 61 rotates together. If the buckle of the medicine strip 11 is lost, damaged, or leaking, the first lever 52 or the second lever 62 will push the medicine strip 11 to the Y-direction reverse side, so that the rotation angle of the first rotary encoder 51 or the second rotary encoder 61 is less than the normal value, thereby achieving the purpose of judging whether there is an abnormality in the upper and lower medicine strips 11; on the other hand, while the first rotary encoder 51 and the second rotary encoder 61 are reading, the screw guide rail assembly 7 drives the nut slider 81 to move so that the first metal sensor 83 and the second metal sensor 84 carried by it respectively obtain the number of metal buckles 111 at the X-direction ends of the upper and lower medicine strips 11, and at the same time, the third metal sensor 85 and the fourth metal sensor 86 carried by it obtain the number of metal buckles 111 at the X-direction reverse end of the previous batch of medicine strips 11, thereby achieving the purpose of detecting whether the metal buckles 111 at both ends of the medicine strip 11 are lost.
