[0036] The present invention will be further described in detail below in conjunction with specific embodiments, but the implementation methods of the present invention are not limited thereto.

[0037] See also Figures 1 to 6 This embodiment provides a double-bag automatic opening carrying device, which includes a box body 100 and two bag storage holes 110.

[0038] The two bag storage holes 110 are arranged side by side in the box body 100 and penetrate the box body 100 along the height direction of the box body 100. The wall surface of at least a part of the bag storage hole 110 is a gradually shrinking surface 111 gradually approaching the center of the bag storage hole 110 from bottom to top, and the gradually shrinking surface 111 can gradually squeeze the corresponding outer wall of the bag body fed into the bag storage hole 110 from bottom to top, so that the opening of the top of the bag body gradually expands in the width direction thereof.

[0039] Since at least a part of the wall surface of the bag storage hole 110 is a gradually shrinking surface 111 gradually approaching the center of the bag storage hole from bottom to top (see Figure 2 ), so when the bag body 500 is fed into the bag storage hole 110 from bottom to top, the gradually contracting surface 111 will gradually squeeze the corresponding outer wall of the bag body 500, and finally the opening at the top of the bag body 500 will gradually expand in the width direction thereof, that is, when the bag body 500 is fed into the bag storage hole 110 from bottom to top, the opening at the top of the bag body 500 will gradually expand, and finally when the bag body 500 reaches the predetermined position, the opening at the top will expand to a suitable size (see Figure 3 ), thereby ensuring that the Chinese medicine particles can smoothly fall into the bag body 500 during subsequent loading without spilling.

[0040] In some preferred embodiments, see Figure 1 and Figure 2 A guide slit 112 is provided on one side of the bag storage hole 110. The guide slit 112 is connected to the bag storage hole 110 and penetrates the box body 100 along the height direction of the box body 100. The guide slit 112 is used to limit the side of the bag body so that it can be inserted therein. The gradually shrinking surface 111 is provided on the side opposite to the guide slit 112.

[0041] That is, when the bag body 500 is fed into the bag storage hole 110 from bottom to top, the side of the bag body 500 will be inserted into the guide slit 112, so that the guide slit can guide the movement of the bag body 500. In addition, since the gradually contracting surface 111 is arranged on the side opposite to the guide slit 112, the opening at the top of the bag body 500 will gradually widen to the left and right sides of the line between the gradually contracting surface 111 and the guide slit 112 during the movement of the bag body 500 from bottom to top.

[0042] In some preferred embodiments, a bag clamping assembly 200 is disposed on the side of the box body 100 , and the bag clamping assembly 200 can lock or unlock the side of the bag body 500 inserted into the bag storage hole 110 .

[0043] Specifically, the bag clamping assembly 200 includes a pin and a spring. The pin can pass through one of the side walls of the guide slot 112 and press the side edge of the bag body located in the guide slot 112 against the other side wall of the guide slot 112. The spring applies a force to the pin so that the pin passes through one of the side walls of the guide slot 112 and presses the other side wall of the guide slot 112.

[0044] For more details, see Figure 1 The two bag storage holes 110 are arranged side by side in the box body 100, one outside and one inside, and the pin includes a first pin 210 and a second pin 220. Figure 4 and Figure 5 The first pin shaft 210 is used to press the side of the bag body 500 in the outer bag storage hole 110. The first pin shaft 210 has a first force-applying surface 211. The first force-applying surface 211 can pass through one side wall of the guide slot 112 corresponding to the outer bag storage hole 110 and press the side of the bag body 500 against the other side wall of the guide slot 112. Figure 4 and Figure 6 The second pin shaft 220 is used to press the side edge of the bag body in the inner bag storage hole 110. The second pin shaft 220 has a second force-applying surface 221. The second force-applying surface 221 can pass through one side wall of the guide slot 112 corresponding to the inner bag storage hole 110 and press the side edge of the bag body against the other side wall of the guide slot 112. Figure 3 and Figure 4 The spring includes a first spring 230 and a second spring 240, one end of the first spring 230 is against the box body 100, and the other end is against the end surface of the first pin shaft 210, and one end of the second spring 240 is against the box body 100, and the other end is against the end surface of the second pin shaft 220.

[0045] It can be seen from the above structure that the first pin shaft 210 only controls the clamping or release of the bag body 500 in the outer bag storage hole 110, and the second pin shaft 220 only controls the clamping or release of the bag body 500 in the inner bag storage hole 110. Therefore, when releasing the bag body 500, only the first pin shaft 210 can be moved to release only the outer bag body 500, or only the second pin shaft 220 can be moved to release only the inner bag body 500, or the first pin shaft 210 and the second pin shaft 220 can be moved at the same time to release both the inner and outer bag bodies 500.

[0046] Among them, see Figure 1 The first spring 230 and the second spring 240 are both arranged close to the outer side of the box body 100. The outer end surface of the first pin shaft 210 abuts against the first spring 230, and the inner end surface extends to the inner side of the box body 100. The outer end surface of the second pin shaft 220 abuts against the second spring 240, and the inner end surface extends to the inner side of the box body 100. Figure 4 and Figure 5 The first pin shaft 210 has an avoidance notch 212 at a position corresponding to the inner guide slot 112 so as to pass over the wall of the guide slot 112 .

[0047] Preferably, see Figure 4 The first pin shaft 210 and the first spring 230 are arranged in a first groove 120 opened on the side of the box body 100 , and the second pin shaft 220 and the second spring 240 are arranged in a second groove 130 opened on the side of the box body 100 .

[0048] Among them, see Figure 4 , Figure 5 as well as Figure 6 The first pin shaft 210 has a notch formed at a position corresponding to the outer guide slot 112, and the first force-applying surface 211 is located on the outer wall of the notch. The second pin shaft 220 also has a notch formed at a position corresponding to the inner guide slot 112, and the second force-applying surface 221 is located on the outer wall of the notch.

[0049] In some preferred embodiments, a flaring structure 113 is formed at the bottom of the bag storage hole 110 to facilitate the bag body to enter the bag storage hole 110 .

[0050] The expansion structure 113 is an arc-shaped surface, which can guide the top of the bag body 500 so that the top of the bag body 500 can smoothly enter the bag storage hole 110.

[0051] In some preferred embodiments, the cross section of the gradually contracting surface 111 is an arc-shaped structure, so that the transition of the gradually contracting surface 111 is smoother, and the outer wall of the bag body 500 can be squeezed gradually and smoothly.

[0052] In some preferred embodiments, the maximum dimension of the bag storage hole 110 in the width direction remains constant.

[0053] In some preferred embodiments, the bag storage hole 110 is a slot hole formed by a mold during the injection molding of the box body 100. Of course, the bag storage hole 110 can also be a slot hole on a separate component, which can be fixed on the housing 100.

[0054] The working principle of the double-bag automatic opening carrying device of this embodiment is as follows:

[0055] In the initial state, under the action of the first spring 230, the first force-applying surface 211 of the first pin shaft 210 passes through one of the side walls of the guide slot 112 corresponding to the outer bag storage hole 110 and is pressed against the other side wall of the guide slot 112; under the action of the second spring 240, the second force-applying surface 221 of the second pin shaft 220 passes through one of the side walls of the guide slot 112 corresponding to the inner bag storage hole 110 and is pressed against the other side wall of the guide slot 112;

[0056] When the bag body 500 needs to be placed in the bag storage hole 110, an external mechanical device can be used to push the inner end surfaces of the first pin shaft 210 and the second pin shaft 220, so that the first force-applying surface 211 and the second force-applying surface 221 can move and leave the corresponding guide slit 112; then, the bag body 500 is sent into the bag storage hole 110 from bottom to top. During the sending process, the gradually shrinking surface 111 will gradually squeeze the corresponding outer wall of the bag body 500, so that the opening at the top of the bag body 500 is expanded in the width direction. The bag body 500 gradually expands, and finally, when the bag body 500 reaches the predetermined position, the opening at the top thereof expands to a suitable size; then, the external mechanical device stops pushing the inner end surfaces of the first pin shaft 210 and the second pin shaft 220, and then, under the action of the first spring 230 and the second spring 240, the first force-applying surface 211 and the second force-applying surface 221 move, clamping the two bag bodies 500 placed in the bag storage hole 110, so that the bag bodies 500 will not fall out of the bag storage hole 110;

[0057] After the medicine is loaded, when the bag body 500 needs to be released, an external mechanical device can be used to push the inner end surfaces of the first pin shaft 210 and the second pin shaft 220 to move the first force-applying surface 211 and the second force-applying surface 221, thereby releasing the clamping of the bag body 500, so that the bag body 500 can leave the bag storage hole 110 under the action of gravity or other external forces; wherein, since the first pin shaft 210 only controls the clamping or release of the bag body 500 in the outer bag storage hole 110, and the second pin shaft 220 only controls the clamping or release of the bag body 500 in the inner bag storage hole 110, when the bag body 500 is released , you can push only the first pin 210 to release only the outer bag body 500, or push only the second pin 220 to release only the inner bag body 500, or push the first pin 210 and the second pin 220 at the same time to release both the inner and outer bag bodies 500; therefore, the way to release the bag body 500 is relatively free, you can release only one bag body 500, or you can release both bag bodies 500 at the same time; of course, when inserting the bag body 500, if there is only one bag body 500, you can also push only one pin, so that the bag body 500 can be placed in the corresponding bag storage hole 110 and clamped.

[0058] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
