[0030] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Detailed Implementation
[0031] The present invention will now be further described with reference to the accompanying drawings.
[0032] Example 1
[0033] like Figure 1 As shown, an automatic medicine box closing device according to this embodiment includes a device body 100. The device body 100 includes a weighing part 101, a closing part 102, and a guide rail. A lower mold 1 is provided on the guide rail, which can reciprocate between the weighing part 101 and the closing part 102. Because the medicine box is small in size, in this embodiment, as... Figure 2 As shown, each lower mold 1 has ten medicine shell holes 11 for holding medicine shells 2, and four lower molds 1 are continuously arranged on the guide rail. Medicine shells 2 are installed in the lower mold 1, and a medicine loading machine for adding medicine into the medicine shells 2 is provided in the weighing part 101.
[0034] In this embodiment, the filling machine is an automatic quantitative powder filling machine customized by the applicant from the manufacturer. It consists of a high-precision sensor, a quantitative scale, and other components. The high-precision sensor is mainly used to provide timely feedback on the weight change of the medicine on the quantitative scale during weighing, ensuring that the control program can control the medicine quality in a timely manner based on the mass change on the quantitative scale. The quantitative scale can weigh the medicine in a timely manner and provide feedback on the medicine weight through the sensor. In addition to the quantitative scale used for weighing, a dedicated scale is also set up for re-inspection of the medicine quality. After the inspection is completed, the medicine quality is automatically recorded in the system and exported through the output port. After the medicine is weighed, it is loaded into the medicine shell 2 through the medicine channel set by the filling device. Since the filling machine is not closely related to the focus of protection of this application, it will not be described in detail in this embodiment. Of course, in some embodiments, the medicine can also be manually added manually.
[0035] like Figure 6 As shown, a cylinder 5 is provided inside the capping part 102 to seal the medicine cap 4 onto the medicine shell 2. The cylinder 5 is installed inside the capping part 102, and its movable end can move up and down. Five pressure blocks 51 are installed at the bottom of its movable end. There are eight cylinders 5 arranged in parallel and continuously inside the capping part 102, which match the number of medicine shells 2 in the lower mold 1.
[0036] like Figure 5 As shown, a wire 41 is threaded through the cap 4. One end of the wire 41 enters the charge case 2 and contacts the gunpowder inside, while the other end extends outward from the cap 4. The top of the cap 4 is provided with a pressure-bearing part 43 that cooperates with the pressure block 51. To prevent the pressure block 51 from contacting the wire 41 when it is pressed down, which could lead to an accident, a clearance groove 511 is provided on the pressure block 51 to ensure that it can smoothly press the cap 4 into the charge case 2 without contacting the wire 41.
[0037] like Figure 4 As shown, the lower mold 1 is detachably equipped with the upper mold 3, and the medicine cap 4 is installed inside the upper mold 3.
[0038] The upper mold 3 includes a fixed part 31, a movable part 32, and a guide connecting post 35 connecting the two. A cap hole 33 for accommodating the cap 4 is formed on the contact surface of the fixed part 31 and the movable part 32. Before sealing the explosive casing 2, the cap 4 is manually installed in the cap hole 33. After the lower mold 1 has finished loading the explosive in the weighing part 101 and entered the cap closing part 102, the upper mold 3 is placed on the lower mold 1, and the cylinder 5 moves down to complete the cap closing and sealing.
[0039] To achieve precise positioning of the medicine cap 4 and the medicine shell 2 (i.e., one-to-one alignment), this embodiment provides a positioning post 12 on the lower mold 1 and a positioning hole 34 that cooperates with the positioning post 12 on the fixing part 31, so as to ensure the precise positioning of the lower mold 1 and the upper mold 3.
[0040] like Figure 7 , Figure 8 and Figure 9 As shown, the guide connecting post 35 includes an optical axis section 352. One end of the optical axis section 352 is provided with a limit ring 351, and the other end of the optical axis section 352 is provided with a threaded section 353. The diameters of the optical axis section 352, the limit ring 351, and the threaded section 353 are arranged from largest to smallest as follows: limit ring 351, optical axis section 352, and threaded section 353.
[0041] A threaded hole 313 is provided on the contact surface between the fixed part 31 and the movable part 32 to mate with the threaded section 353. A second optical hole 324 is provided on the contact surface between the movable part 32 and the fixed part 31 for the threaded section 353 to pass through. A first optical hole 323 is provided on the side wall of the movable part 32 for the optical axis section 352 to pass through. The first optical hole 323 and the second optical hole 324 are connected. A spring 36 is sleeved on the outer side of the optical axis section 352. The two ends of the spring 36 abut against the end faces of the limiting ring 351 and the second optical hole 324, respectively. The spring 36 is always under pressure, so it has a force to drive the movable part 32 to move towards the fixed part 31. When the medicine cap 4 is inserted, the medicine cap 4 can be reliably clamped. After the medicine cap 4 is placed on the medicine shell 2, the movable part 32 moves towards the fixed part 31 and fits tightly against the fixed part 31.
[0042] In this embodiment, the inner diameter of the first aperture 323 is slightly larger than the outer diameter of the spring 36, so that the movable part 32 can move smoothly. The inner diameter of the second aperture 324 is slightly larger than the outer diameter of the threaded section 353, so that the threaded section 353 can pass through it smoothly. The inner diameter of the second aperture 324 is smaller than the outer diameter of the optical axis section 352, so that the spring 36 can abut against its end face.
[0043] like Figure 3 , Figure 10 and Figure 11 As shown, a sealing groove 21 is provided on the inner wall of the medicine casing 2, and a sealing protrusion 42 that mates with the sealing groove 21 is provided on the side wall of the medicine cap 4. After the cap is closed, the two can be reliably connected and are not easy to loosen.
[0044] The side wall of the fixed part 31 with the medicine cap hole 33 is provided with a first clamping surface 311 that abuts against the medicine cap 4 and a first clearance part 312 that does not contact the medicine cap 4 from top to bottom. The side wall of the movable part 32 with the medicine cap hole 33 is provided with a second clamping surface 321 that abuts against the medicine cap 4 and a second clearance part 322 that does not contact the medicine cap 4 from top to bottom.
[0045] After the medicine cap 4 is inserted, the movable part 32 moves outward, and the spring 36 has the elastic force to drive it back to its original position, so that the inner wall of the medicine cap hole 33 formed by the first clamping surface 311 and the second clamping surface 321 can reliably clamp the medicine cap 4. The pressure block 51 moves down, driving the medicine cap 4 to move down and be inserted into the medicine shell 2. After the medicine cap 4 is removed from the upper mold 3, the movable part 32 returns to its original position and is tightly attached to the fixed part 31. At this time, the first clearance part 312 and the second clearance part 322 do not contact the medicine cap 4, so that the upper mold 3 can be smoothly removed from the lower mold 1 for the next round of capping operation.
[0046] This equipment uses a servo motor to drive the lower mold 1 to move on the guide rail. After the gunpowder is loaded into the explosive casing 2, the cylinder 5 presses the explosive cap 4 on the upper mold 3 onto the explosive casing 2 to complete the capping action.
