[0035] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0036] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0037] This embodiment provides a calibration device 100 for a dual-interface medicine bag, used to calibrate the sealing position of the dual interfaces and the medicine bag film to improve product quality. It includes a sliding mechanism 110, a calibration mechanism 120, and an adjustment mechanism 130. The various components of the calibration device 100 are described in detail below.

[0038] like Figure 1 As shown, the sliding mechanism 110 consists of a slide rail 111, a slide base 112, and a laser rangefinder sensor 113. The slide rail 111 is generally a flat cuboid with sliding grooves machined on both sides for mounting the slide base 112. The sliding grooves penetrate two surfaces of the slide rail 111 that are perpendicular to each other. Several sets of magnets are provided on the bottom surface of the slide rail 111 at certain intervals to directly attach the entire calibration device 100 to the bag making and sealing machine, eliminating the need to drill new holes on the equipment to install the calibration device 100.

[0039] The interior of the slide block 112 is machined to match the cross-section of the slide rail 111. Several slide blocks 112 are mounted on the slide rail 111 and arranged at equal intervals. Each slide block 112 can be individually controlled and moves on the slide rail 111. The upper surface of the slide block 112 is machined with threaded holes of different specifications. The threaded holes on the front and rear sides of the slide block 112 have smaller diameters, while the larger diameter threaded holes are located in the middle of the upper surface of the slide block 112 and are perpendicular to the two surfaces of the slide rail 111. Laser rangefinder sensors 113 are mounted on the front of the slide blocks 112, with the same number of sensors as the slide blocks 112. The end face with the detection function faces the same direction and is parallel to the slide rail 111. Locking bolts are installed on the rear of the slide blocks 112. When the end face of the locking bolts presses against the slide rail 111, the slide blocks 112 are fixed to the slide rail 111.

[0040] The adjustment mechanism 130 consists of a servo motor 131, a bracket 132, a left-hand screw 133, and a right-hand screw 134. For example... Figure 2 As shown, the bracket 132 is an L-shaped plate with a reinforcing rib welded in the middle to strengthen its structural strength. One end of the bracket 132 has a through hole, and the other end has a threaded hole. The through hole is used to fix the bracket 132 to the front and rear sides of the upper surface of the slide block 112, and the threaded hole is used to mount the servo motors 131. The shafts of the two servo motors 131 are fixedly connected to a left-handed screw 133 and a right-handed screw 134, respectively, and pass through the bracket 132. The other ends of the screws pass through the threaded holes on the drive part 1213 of the movable block 121. The right-handed screw 134 is located on the front side of the slide block 112, and the left-handed screw 133 is located on the opposite side.

[0041] The thread direction machined in the threaded hole is the same as the thread direction of the screw passing through the hole, so that when the screw rotates under the drive of the servo motor 131, the drive unit 1213 drives the movable block 121 to reciprocate. When the servo motor 131 rotates clockwise, the right-hand screw 134 is in the tightening direction, and the drive unit 1213 cooperating with the right-hand screw 134 drives the movable block 121 to move towards the servo motor 131; the left-hand screw 133 is in the loosening direction, and the drive unit 1213 cooperating with the left-hand screw 133 drives the movable block 121 to move away from the servo motor 131, thus reducing the distance between the two movable blocks 121. To increase the distance between the two movable blocks 121, the servo motor 131 needs to rotate counterclockwise.

[0042] See Figures 3 to 5 The calibration mechanism 120 is composed of a movable block 121 and a fixed block 122. For example... Figure 4 As shown, the cross-sectional shape of the fixing block body 1221 is waist-shaped, with a T-shaped groove 1222 of a certain depth formed at one end. The T-shaped groove 1222 penetrates the arc surfaces on both sides of the fixing block body 1221. The surface roughness of the inner surface of the T-shaped groove 1222 is 0.8 micrometers to reduce the frictional resistance when the movable block 121 slides. A mounting portion 1223 of a certain height is formed on the plane of the other end of the fixing block body 1221. The width of the mounting portion 1223 is equal to the width of the fixing block body 1221, while its length is much greater than the length of the fixing block body 1221. Furthermore, mounting through holes are provided at both ends of the mounting portion 1223 for mounting the fixing block 122.

[0043] like Figure 5 As shown, a limiting post 1211 is formed on the upper surface of the movable block body 1212. The limiting post 1211 is cylindrical with a diameter much smaller than the width of the movable block body 1212, and the end away from the movable block body 1212 is rounded. A T-shaped block 1214 is formed on the lower surface of the movable block body. The surface roughness of the outer surface of the T-shaped block 1214 is 0.8 micrometers to reduce frictional resistance during sliding. The T-shaped block 1214 is installed inside the T-shaped groove 1222 and slides within the T-shaped groove, thereby realizing the reciprocating motion of the movable block 121. A driving part 1213 is provided on one side of the movable block body 1212 for driving the movable block 121. The driving part 1213 is machined with threaded holes for connecting the left-hand screw 133 and the right-hand screw 134.

[0044] See Figures 1 to 3During assembly, the calibration device 100 for the dual-interface medicine bag first installs several slide blocks 112 onto the slide rail 111. Lubricant is applied to the T-shaped blocks 1214 of the movable block 121 and the T-shaped grooves 1222 of the fixed block 122 to reduce the frictional resistance when the movable block 121 slides. The T-shaped blocks 1214 of the two movable blocks 121 are then placed within the T-shaped grooves 1222 of the fixed block 1221, ensuring the two movable blocks 121 fit tightly together.

[0045] Then, the entire calibration mechanism 120 is installed onto the slide 112, ensuring that the mounting through hole on the fixing block 122 coincides with the center of the threaded hole at the middle position of the upper surface of the slide 112. The bolts are then tightened to fix the calibration mechanism 120 and the slide 112 as a whole. Finally, the corresponding mounting through hole on the bracket 132 is aligned with the center of the threaded holes on the front and rear sides of the upper surface of the slide 112. Bolts are then installed in the combination structure of the mounting through hole and the threaded hole, connecting the bracket 132 and the slide 112 as a whole. A screw fixedly connected to the shaft of the servo motor 131 passes through the bracket 132 and the drive unit 1213. A right-hand screw 134 is installed on the front side of the slide 112, and a left-hand screw 133 is installed on the rear side of the slide 112. The servo motor 131 is then fixed to the bracket 132 with bolts.

[0046] Repeat the above steps to assemble the calibration mechanism 120, the bracket 132 and the servo motor 131 on several slides 112, thereby forming a calibration device 100 for a dual-interface medicine bag.

[0047] Combination Figure 1 and Figure 2 The implementation method of the dual-interface medicine bag calibration device is described in detail. For example... Figure 1 As shown, the dual-port 200 of the medicine bag consists of two parallel ports and a reinforcing plate between the two ports, with one end of each port not closed; the unclosed end of the dual-port 200 is sealed with the medicine bag film.

[0048] The calibration device 100 is directly attached to the bag-making and sealing machine via a magnet at the bottom of the slide rail 111. The power to the laser rangefinder 113 is then turned on. Each subsequent laser rangefinder 113 detects the distance of the previous laser rangefinder 113 and returns the detection result to the control host. Based on the detection result, the position of the slide block 112 is adjusted so that the limiting post 1211 of the calibration mechanism 120 is aligned with the center position of the clamp of the bag-making and sealing machine. Since the clamps are arranged at equal intervals, the position of each slide block 112 is adjusted sequentially to ensure that each slide block 112 is aligned with the clamp of the bag-making and sealing machine. The locking bolts are tightened to fix the slide block 112 to the slide rail 111, preventing the slide block 112 from shifting position during operation.

[0049] The double-port 200 of the medicine bag enters the bag making and sealing machine through the hopper. After the internal mechanism of the bag making and sealing machine is adjusted so that the unsealed end of the double-port 200 faces the clamp, it is then blown into the clamp by compressed gas, and the clamp holds the double-port 200.

[0050] Then the clamp is released, allowing the dual-port 200 to be inserted into the limiting post 1211 under the action of gravity. As the unclosed end face of the dual-port 200 contacts the upper surface of the movable block body 1212, the dual-port 200, which has deviated from the correct position, is calibrated.

[0051] Finally, the clamp closes again to hold the double-port 200 of the medicine bag, and then the bag making and sealing machine seals the double-port 200 and the medicine bag film. Several slides 112 are installed on the slide rail 111 at certain intervals. The position of the slides 112 is adjusted according to the information detected by the laser range sensor 113, so that the double-port 200 in the off-position is calibrated when it is inserted into the limiting post 1211 under the action of gravity. Then the double-port 200 is clamped by the clamp and enters the next process, thereby ensuring the quality of the product.

[0052] In addition, the calibration device 100 can also adapt to dual interfaces 200 of different specifications. The distance between the two movable blocks 121 is adjusted by rotating the screw driven by the servo motor 131. When the servo motor 131 rotates clockwise, the right-hand screw 134 tightens, and the drive unit 1213 corresponding to the right-hand screw 134 moves the movable block 121 towards the servo motor 131; the left-hand screw 133 loosens, and the drive unit 1213 corresponding to the left-hand screw 133 moves the movable block 121 away from the servo motor 131, thereby reducing the distance between the two movable blocks 121. To increase the distance between the two movable blocks 121, the servo motor 131 needs to rotate counterclockwise.

[0053] If the left-hand screw 133 and the right-hand screw 134 are installed in opposite positions, the movement direction of the two movable blocks 121 will be opposite to the above movement direction. That is, when the servo motor 131 rotates clockwise, the distance between the two movable blocks 121 increases, and when the servo motor 131 rotates counterclockwise, the distance between the two movable blocks 121 decreases.

[0054] The above embodiments are merely a more detailed description of the present utility model. For those skilled in the art, modifications or equivalent substitutions can still be made to the technical solutions in the foregoing embodiments. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model patent.
