Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1, the opening forming apparatus in the embodiment of the present utility model includes a clamping mechanism 100, an adsorption mechanism 300, a forming pestle 200, and a driving module 400, wherein the clamping mechanism 100 is used for clamping a medicine bag 10, and the adsorption mechanism 300 is used for assisting the forming pestle 200 to prop open the medicine bag 10, so that the medicine bag 10 is formed.

In particular, referring to fig. 1 and 2, the clamping mechanism 100 may include two clamp blocks 110 disposed opposite each other, and the two clamp blocks 110 may be moved closer to or farther from each other to change the gap between the two clamp blocks 110. When the clamping mechanism 100 needs to clamp the medicine bag 10, the two clamping blocks 110 can be separated from each other, so that the distance between the two clamping blocks 110 is increased, and the medicine bag 10 is placed between the two clamping blocks 110. The two clamp blocks 110 are then brought closer together, the two clamp blocks 110 cooperating to clamp the pouch 10.

When the clamping mechanism 100 clamps the medicine bag 10, the medicine bag 10 is flat, and has an opening 11 at the top, and the opening 11 can be regarded as a slit structure.

The adsorption mechanism 300 may include two adsorption assemblies 311 disposed opposite to each other, and the two adsorption assemblies 311 are respectively used for adsorbing two opposite surfaces of the medicine bag 10, so that the two opposite surfaces are far away from each other, and at this time, the opening 11 of the medicine bag 10 is opened. The shaped pestle 200 is positioned above the pouch 10 and the drive module 400 is operable to drive the shaped pestle 200 from the opening 11 of the pouch 10 into the interior of the pouch 10 to thereby open the pouch 10. After the pouch 10 is opened and formed, the driving module 400 may be further used to drive the forming pestle 200 to leave the pouch 10 through the opening 11 of the pouch 10, so that the clamping mechanism 100 can clamp the pouch 10 to enter the next process.

Referring to fig. 3, the forming pestle 200 in this embodiment includes a connecting rod 210 and a tapered structure 220, wherein the tapered structure 220 has opposite first and second ends, the first end having a cross-sectional dimension that is greater than the cross-sectional dimension of the first end. The first end of the tapered structure 220 is fixedly connected to the connecting rod 210, the second end is close to the pouch 10, and when the forming pestle 200 is inside the pouch 10 through the opening 11 of the pouch 10, the second end of the tapered structure 220 first enters the opening 11 of the pouch 10. It can be appreciated that the tip of the tapered structure 220 enters the opening 11 first, which is convenient for expanding the medicine bag 10 step by step in the process of entering the medicine bag 10 step by the forming pestle 200, so as to avoid the situation of tearing caused by overlarge deformation of the medicine bag 10. Also, the smaller size of the second end of the tapered structure 220 provides easier access to the opening 11 of the pouch 10, thereby facilitating the feeding of the formed pestle 200 into the interior of the pouch 10.

In this embodiment, referring back to fig. 1 and 2, the drive module 400 may include a first drive module 410, where the first drive module 410 may be used to drive the forming pestle 200 to move in a first direction, where the first direction may be understood as the height direction. Specifically, the first driving module 410 may include a first fixing base 411, a first rail 412, a first lead screw nut mechanism 413, and a first motor 414, where the first rail 412 is disposed on the first fixing base 411, and the first rail 412 extends along a first direction. The forming pestle 200 can be connected to the first guide rail 412 through the connecting rod 210, and the forming pestle 200 is in transmission connection with the first screw nut mechanism 413, when the first motor 414 drives the first screw nut mechanism 413 to move, the first screw nut mechanism 413 can drive the forming pestle 200 to move along the first direction relative to the first guide rail 412, so that the purpose of approaching to the medicine bag 10 or keeping away from the medicine bag 10 is achieved.

Referring to fig. 4, the suction assembly 311 may include a vacuum chuck base 311 and a plurality of vacuum chucks 312, the vacuum chuck base 311 being provided with suction holes (not shown) in one-to-one correspondence with the plurality of vacuum chucks 312, each vacuum chuck 312 being in communication with the vacuum chuck base 311 through the corresponding suction hole. Specifically, the vacuum chuck base 311 may be communicated with an external air extracting device, and the air extracting device is used for extracting air from the vacuum chuck base 311, so that the interior of the vacuum chuck base 311 is in a vacuum or negative pressure state. The vacuum chuck 312 is communicated with the vacuum chuck seat 311, so that the vacuum chuck 312 is kept in a vacuum or negative pressure state, and the vacuum chuck 312 can absorb the medicine bag 10 when being stuck on the surface of the medicine bag 10.

The plurality of vacuum chucks 312 may be arranged along the height direction of the pouch 10, so that the plurality of vacuum chucks 312 may have a relatively uniform adsorption force on each portion of the pouch 10, and the pouch 10 may be better opened.

As shown in fig. 2, when the suction mechanism 300 and the clamping mechanism 100 act on the medicine bag 10 at the same time, the suction assembly 311 on the same side can be disposed on the side of the clamping block 110 away from the other clamping block 110, so that the clamping effect of the clamping block 110 on the medicine bag 10 is not affected. In addition, in order to facilitate the adsorption assembly 311 to adsorb the medicine bag 10, each clamping block 110 may further be provided with an avoiding groove 112 for avoiding the vacuum chuck 312, so that when the clamping block 110 clamps the medicine bag 10, the adsorption assembly 311 may further pass through the avoiding groove 112 of the clamping block 110 to contact with the surface of the medicine bag 10, thereby playing an adsorption effect.

In this embodiment, with continued reference to fig. 1 and 2, the driving module 400 further includes a second driving module 420, where the second driving module 420 is configured to drive the adsorption mechanism 300 to move along a second direction so that the adsorption assembly 311 approaches or moves away from the medicine bag 10, and the second direction is perpendicular to the first direction. It will be appreciated that the second drive module 420 drives the adsorption mechanism 300 adjacent to the pouch 10 and adsorbs the surface of the pouch 10 before the formed pestle 200 enters the pouch 10, such that the opening 11 of the pouch 10 is opened. The second drive module 420 then drives the suction mechanism 300 away from the pouch 10 so that the subsequent forming pestle 200 can access the interior of the pouch 10 through the opening 11 of the pouch 10 and open the pouch 10 to form the pouch 10.

Further, the second driving module 420 may include a second fixing seat 421, a second guide rail 422, a second screw nut mechanism 423, and a second motor 424, wherein the second guide rail 422 is disposed on the second fixing seat 421, and the second guide rail 422 extends along a second direction. The adsorption mechanism 300 may be connected to the second guide rail 422 through a slider, and the adsorption mechanism 300 is in transmission connection with the second screw nut mechanism 423, and when the second motor 424 drives the second screw nut mechanism 423 to move, the second screw nut mechanism 423 may drive the adsorption mechanism 300 to move along the second direction relative to the second guide rail 422.

In the present embodiment, the first driving module 410 may be further connected to the second fixing seat 421 through the first fixing seat 411, so that the structure between the first driving module 410 and the second driving module 420 is compact, so as to reduce the total volume of the opening forming device, and further save the occupied space.

In some embodiments, referring to fig. 2 and 5 together, the side of each clamp block 110 facing the other clamp block 110 is provided with a V-shaped groove 111, which V-shaped groove 111 can be used to receive the portion of the pouch 10 that is being opened when the shaped pestle 200 is introduced into the interior of the pouch 10 and after the pouch 10 is opened. That is, after the forming pestle 200 enters the inside of the pouch 10, both surfaces of the pouch 10 are deformed toward the V-shaped groove 111, respectively, until they are fitted to the groove walls of the V-shaped groove 111. Due to the V-shaped groove 111, when the medicine bag 10 is deformed under the action of the forming pestle 200, and the forming pestle 200 leaves the medicine bag 10, the V-shaped groove 111 can help the medicine bag 10 maintain the opened shape, so that the medicine bag 10 can be prevented from rebounding to the original shape.

It should be noted that during the process of the forming pestle 200 entering the inside of the pouch 10 and expanding the pouch 10, the two side edges of the pouch 10 along the second direction gradually move toward the center of the pouch 10, and the portion of the clip 110 originally used to hold the edge of the pouch 10 is no longer applied to the pouch 10. To ensure that the clamping blocks 110 always maintain the clamping effect on the medicine bag 10, a reset structure (not shown) may be provided between the two clamping blocks 110, the reset structure may be provided at two opposite sides of the V-shaped groove 111 along the second direction, and two ends of the reset structure are respectively connected to the two clamping blocks 110. The reset structure is used for generating acting force for enabling the two clamping blocks 110 to be close to each other, when the edge of the medicine bag 10 moves towards the V-shaped groove 111, a gap appears between the positions of the edge of the clamping block 110, which are originally used for clamping the medicine bag 10, at this time, the reset structure can enable the two clamping blocks 110 to be close to each other, so that the positions of the edge of the two clamping blocks 110, which are originally used for clamping the medicine bag 10, are mutually attached to ensure that the two clamping blocks 110 always have good clamping effects on the medicine bag 10.

In this embodiment, the return structure may be, for example, a spring mechanism that is in a stretched state when the two clamping blocks 110 are in an initial state of clamping the medicine bag 10, at which time the spring mechanism generates an elastic return force for causing the two clamping blocks 110 to have a tendency to approach each other. When the formed pestle 200 spreads the pouch 10, the portion of the two clamping blocks 110 that is originally used to clamp the edge of the pouch 10 loses the supporting function of the pouch 10, and the two clamping blocks 110 can approach each other under the action of the spring mechanism. Alternatively, the reset structure may be, for example, two magnets that attract each other, wherein the edge of the pouch 10 is located between the two magnets in the initial state, and wherein the two magnets attract each other such that the two clamping blocks 110 approach each other when the edge of the pouch 10 moves toward the V-groove 111 and the edge of the pouch 10 moves away from between the two magnets.

In some embodiments, referring to fig. 1 or 2, there may be two forming pestles 200, two forming pestles 200 being arranged in parallel, and correspondingly, there are two holding mechanisms 100 and suction mechanisms 300. It will be appreciated that by providing two forming pestles 200, two bags 10 can be formed simultaneously, which is advantageous for improving production efficiency.

As shown in fig. 1, when two forming pestles 200 are provided, the two forming pestles 200 may share one first driving module 410, and in this case, the number of first rails 412 is two, each forming pestle 200 is connected to one first rail 412 through one slider 500, and the two sliders 500 may also be in an integral structure. Thus, not only the first screw nut mechanism 413 can drive the two forming pestles 200 to synchronously move, but also the integration level of the device can be conveniently improved.

Further, in the two suction mechanisms 300, two suction assemblies 311 located in the middle may share one vacuum chuck base 311, that is, two opposite sides of the vacuum chuck base 311 are respectively connected with a vacuum chuck 312. When the middle vacuum chuck seat 311 works, two medicine bags 10 can be adsorbed simultaneously, so that the operation is convenient, and the volume of the device can be reduced.

It will be apparent to those skilled in the art that various modifications and variations can be made to the embodiments of the present utility model without departing from the spirit and scope of the utility model. Thus, it is intended that the present utility model also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
