Description

Technical Field

[0001] The utility model relates to the technical field of capsule detection, in particular to a capsule metal detector. Background Art

[0002] In the drug production process, capsules are often used to package drug pellets. Conventional capsule metal detection devices generally perform metal detection on packaged and large-scale capsules. This detection method cannot accurately detect individual capsules. Even if a batch of capsules with excessive metal content is found, multiple cycles of screening are still required. It is not suitable for small-batch precise detection and is time-consuming and labor-intensive.

[0003] When testing bulk capsules, conventional testing devices often experience material jamming, and the material distribution is complicated, which is not conducive to testing.

[0004] Therefore, there is an urgent need for a new type of detection device that can achieve one-time accurate detection. Utility Model Content

A lower notch is provided on the right side of the feeding port and on a second inclined panel at the bottom of the feeding box, and a lower roller is provided in the lower notch.

[0008] The detection mechanism includes a detection track with its upper end mounted at the feed port, the detection track being a rectangular inclined cavity, a plurality of deceleration arcs being arranged at the inner bottom of the detection track, a plurality of metal detectors being arranged at the outer top of the detection track, and a photoelectric switch being arranged on the upper end surface of the tail end of the detection track;

[0010] Furthermore, motor vibrators are installed on the front and rear end surfaces of the outer side of the loading box, and a pneumatic vibrator is installed at the bottom of the loading box. The loading box is supported by four support columns at the bottom and shock-absorbing rubber is fixed to the bottom of each support column.

[0011] Furthermore, the bottom of the loading box is composed of a first inclined bottom plate and a second inclined bottom plate inclined toward the lower left, the inclination angle of the first inclined bottom plate is 15 degrees, and the inclination angle of the second inclined bottom plate is 30 degrees.

[0012] Furthermore, the upper roller is connected to the motor a fixed on the left side wall of the loading box through the upper roller, and the lower roller is connected to the motor b fixed on the bottom of the loading box through the lower roller.

[0029] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in a variety of different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 5As shown, the utility model includes a feeding mechanism, a detection mechanism and a feeding mechanism, the feeding mechanism includes a square feeding box 1, a feeding port 2 is provided on the left side of the bottom end of the feeding box 1, the feeding port 2 can ensure that only a single capsule 2 is allowed to enter at a time, which is determined by the distance between the upper roller 201 at the position of the feeding port 2 and the lower end face of the detection track 3, an upper notch 2011 is provided on the upper end of the feeding port 2 and an upper roller 201 is provided in the upper notch 2011, a lower notch 204 is provided on the second inclined panel 208 located on the right side of the feeding port 2 and at the bottom of the feeding box 1, and a lower roller 205 is provided in the lower notch 204; the upper roller 210 and the lower roller 205 can rotate to clear the feeding port 2 when it is blocked.

[0032] The detection mechanism includes a detection track 3 whose upper end is installed at the position of the feed port 2. The detection track 3 is a rectangular inclined cavity. A plurality of deceleration arcs 301 are provided at the inner bottom of the detection track 3. A plurality of metal detectors 302 are provided at the outer top of the detection track 3. A photoelectric switch 303 is provided on the upper end surface of the tail end of the detection track 3. The photoelectric switch 303 can monitor the position of unqualified capsules 9 when they are about to enter the buffer plate 4 to ensure that the dispensing cylinder 5 is pushed out in time.

[0033] The material distribution mechanism includes a buffer plate 4 connected to the tail end of the detection track 3 and an arc groove is provided in the center of the buffer plate 4. The arc groove here has the function of slowing down and temporarily intercepting the capsule 9. A material distribution cylinder 5 is provided behind the buffer plate 4. A sponge block 501 is fixed on the piston rod of the material distribution cylinder 5. The sponge block 501 prevents impact damage to the outer surface of the capsule 9 when pushing the capsule 9. The material distribution mechanism also includes a qualified material box 6 installed on the left side of the buffer plate 4 for collecting qualified materials, and a screening material box 7 installed at the front end of the buffer plate 4 for collecting unqualified capsules 9.

[0034] A motor vibrator 101 is installed on the front and rear end surfaces of the outer side of the feeding box 1, which can make the feeding box 1 vibrate back and forth to ensure that the capsule 9 can be inserted into the feed port 2 from the left and right. A pneumatic vibrator 102 is installed at the bottom of the feeding box 1, which can make the feeding box 1 vibrate up and down to improve the efficiency of entering the detection track 3. The feeding box 1 is supported by four support columns 103 at the bottom and a shock-absorbing rubber 104 is fixed to the bottom of each support column 103.

[0035] like Figure 3 and Figure 4 The bottom of the loading box 1 is composed of a first inclined bottom plate 207 and a second inclined bottom plate 208 inclined to the lower left. The inclination angle of the first inclined bottom plate 207 is 15 degrees, and the inclination angle of the second inclined bottom plate 208 is 30 degrees. The different inclination angles of the two can make the capsules 9 in the box tilt and slide down, preventing a single capsule 9 in the residual material from being retained in the box.

[0036] The upper roller 201 is connected to the motor a203 fixed on the left side wall of the loading box 1 through the upper roller 202, and the lower roller 205 is connected to the motor b206 fixed on the bottom of the loading box 1 through the lower roller. The minimum distance between the upper roller 201 and the lower end face of the detection track 3 is five-sixths of the diameter of the capsule 9, that is, only a single capsule 9 is allowed to enter at a time.

[0037] Each metal detector 302 is connected to a separate speaker module 304, which will sound an alarm when it detects that the sliding capsule 9 contains metal. Each metal detector 302 is perpendicular to the deceleration arc 301 in the detection track 3. A coil is set in the metal detector 302, and the alternating current in the coil forms a magnetic field. The capsule 9 containing metal passing by generates changing eddy currents in the magnetic field, which are detected by the detector. Figure 4 As shown, each capsule has the lowest speed and is closest to the metal detector 302 when passing the highest point of the deceleration arc 301, so as to ensure the accuracy of detection. There are two deceleration arcs 301 between each metal detector 302 to prevent them from being too close and affecting each other. The front and rear width of the detection track 3 is seven-fifths of the length of the capsule 9, that is, only a single capsule is allowed to roll down at a time to prevent detection errors caused by sliding side by side.

[0038] The right side of the qualified material box 6 is provided with an opening connected with the buffer plate 4, and the left inner wall of the qualified material box 6 is installed with a sponge plate 601. When the metal capsule 9 rolls onto the buffer plate 4, it can smoothly enter the qualified material box 6. The rear end face of the screening material box 7 is provided with an opening connected with the buffer plate 4, and the front end inner wall of the screening material box 7 is installed with a sponge plate 601. After the unqualified capsules 9 are detected in turn and pass through the photoelectric switch 303, the piston rod of the material distribution cylinder 5 is quickly pushed out, and when the capsule 9 passes through the arc groove of the buffer plate 4 and is decelerated, it is pushed into the screening material box 7.

[0039] The material distribution cylinder 5 is fixed on the air pump box 8, and an electric control box 3021 is arranged behind the detection track 3. The air pump box 8 has an air pump and related conventional pneumatic valves and other components built in to provide power for the screening cylinder 5 and the pneumatic vibrator 102; the electric control box 3021 has a power supply for providing alternating current for the metal detector 302, as well as conventional components such as a DC power supply and a PLC connected to other electronic control components in the utility model. The relevant circuit connections are all existing technologies and will not be repeated here.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
