Description

Technical Field

[0001] The utility model relates to the technical field of automatic preparation of bagged products, in particular to a packaging bag carrying device, a carrying box conveying mechanism and a Chinese medicine formula granule dispensing device. Background Art

[0002] In automatic preparation equipment for bagged products, a packaging bag carrying device is usually provided. The packaging bag carrying device can convey the packaging bag with bottom and side seals in a predetermined direction under the action of a conveying mechanism. During the conveying process, the feeding, top sealing, bag dropping and other actions are completed in sequence to finally form the final product.

[0003] In the current automatic preparation equipment for bagged products, after the bag-making mechanism has made the packaging bag, it will place the packaging bag from top to bottom into the packaging bag carrying device. After the feeding is completed, when the bag is dropped, the packaging bag leaves the packaging bag carrying device from top to bottom by gravity or other external mechanisms. In the above process, since the bag-making mechanism places the packaging bag into the packaging bag carrying device from top to bottom, the setting height of the bag-making mechanism must be higher than the packaging bag carrying device, which is not conducive to the use of space. For example, in the quantitative preparation equipment for Chinese herbal medicine granules disclosed in the Chinese patent with publication number CN111645887A, the height of the bag-making mechanism is higher than the packaging bag carrying device, which causes the top of the preparation equipment to bulge to a certain height, resulting in poor space utilization.

[0004] In this regard, the applicant believes that if the structure of the existing packaging bag carrying device is improved so that the packaging bag can be placed in the packaging bag carrying device from bottom to top, then the bag making mechanism can be set below the packaging bag carrying device, thereby improving space utilization and making the top of the automatic bagged product preparation equipment no longer protruding, and the bag making mechanism is hidden in the casing below the packaging bag carrying device. Utility Model Content

[0005] The technical problem to be solved by the utility model is to improve the existing packaging bag carrying device so that the packaging bag can be placed therein from the bottom thereof, and the placed packaging bag can be stabilized, and at the same time, the placed packaging bag can also leave from the bottom of the packaging bag carrying device.

[0006] In order to solve the above technical problems, in a first aspect, the utility model provides a packaging bag carrying device, comprising:

[0007] case;

[0008] An accommodating cavity, used to accommodate a packaging bag, the accommodating cavity is arranged to penetrate the height direction of the shell and has openings at the bottom and the top;

[0010] The elastic member applies a force to the clamping member to maintain the first position state.

[0011] The beneficial effects of the above packaging bag carrying device are:

[0012] In the above-mentioned packaging bag carrying device, since the accommodating cavity for placing the packaging bag is open at the top and the bottom, the packaging bag can be placed from the bottom of the accommodating cavity when the packaging bag is placed. Before placing the packaging bag, a force is first applied to the clamping member to switch it to the second position state, and then the packaging bag can be smoothly placed into the accommodating cavity from the bottom of the accommodating cavity. After the placement, the force applied to the clamping member is released, and then the clamping member automatically switches to the first position state under the action of the elastic member, so that the packaging bag placed in the accommodating cavity is clamped and will not fall out of the accommodating cavity. When the packaging bag needs to be taken away from the bottom of the accommodating cavity, a force can be applied to the clamping member again to switch it to the second position state, and then the packaging bag can leave the bottom of the accommodating cavity under the action of gravity and / or other external forces.

[0013] It can be seen that the structure of the above-mentioned packaging bag carrying device solves the technical problem to be solved by the utility model. The packaging bag can be placed into the packaging bag carrying device from the bottom thereof, and the placed packaging bag can be clamped. At the same time, the placed packaging bag can also leave from the bottom of the packaging bag carrying device. After the above-mentioned packaging bag carrying device is applied to the automatic preparation equipment for bagged products, the bag making mechanism can be arranged below the packaging bag carrying device, thereby improving the space utilization rate, so that the top of the automatic preparation equipment for bagged products is no longer protruding, and the bag making mechanism is hidden in the casing below the packaging bag carrying device.

[0033] The accommodating cavity 110 is used to accommodate a packaging bag placed therein. The accommodating cavity 110 is arranged to penetrate the height direction of the shell 100 and has openings at the bottom and the top.

[0034] The clamping member 200 is arranged on the side of the shell 100, and the clamping member 200 can be switched between a first position state and a second position state; wherein, when in the first position state, the clamping member 200 can clamp the packaging bag placed in the accommodating cavity 110, and when in the second position state, the clamping member 200 can release the clamping of the packaging bag placed in the accommodating cavity 110.

[0035] The elastic member 300 is disposed corresponding to the clamping member 200 , and the elastic member 300 applies a force to the clamping member 200 to maintain the first position state.

[0036] The accommodating cavity 110 may be a cavity structure that directly penetrates the housing 100, or a sleeve structure that is separately added and penetrates the housing. Preferably, the accommodating cavity 110 shown in the embodiment in the figure is a cavity structure that directly penetrates the housing 100, and the accommodating cavity 110 is formed by being limited by the mold during the injection molding of the housing 100.

[0037] In order to guide the movement of the clamping member 200, in some embodiments, the packaging bag carrying device of the present invention further includes a guide rod 400. The guide rod 400 is arranged corresponding to the clamping member 200 and fixed to the housing 100, and is used to guide the clamping member 200 to move between the first position state and the second position state.

[0038] For details, see Figure 2 , Figure 3 as well as Figure 6The inner side of the clamping member 200 is provided with two vertical plates 220, and the two vertical plates 220 are provided with corresponding holes. The clamping member 200 is sleeved on the guide rod 400 through the holes, and the clamping member 200 can move along the guide rod 400 with the help of the holes to switch between the first position state and the second position state. The elastic member 300 is a spring, which is sleeved on the guide rod 400, and one end of the elastic member 300 is against the housing 100, and the other end is against one of the vertical plates 220 of the clamping member 200.

[0039] Preferably, in order to improve the stability of the guide and prevent the clamping member 200 from shaking or deviating when moving, two guide rods 400 are provided, the two guide rods 400 are arranged at intervals, and each of the two guide rods 400 is sleeved with an elastic member 300. The clamping member 200 is sleeved on the two guide rods 400 at the same time through the holes provided on the two vertical plates 220.

[0040] Preferably, see Figure 2 or Figure 3 A force plate 230 is also provided on one side of the clamping member 200, and the force plate 230 serves to receive external force so that the clamping member 200 can switch from the first position state to the second position state along the guide rod 400.

[0041] In some embodiments, see Figure 4 and Figure 5 At least a portion of the inner wall of the accommodating cavity 110 is gradually contracted from the bottom to the top.

[0042] The purpose of designing the accommodating cavity 110 into the above-mentioned gradual contraction shape is: on the one hand, the opening at the bottom of the accommodating cavity 110 can be made larger than the opening at the top, so as to facilitate the packaging bag g2 to be smoothly placed into the accommodating cavity 110 from the bottom of the accommodating cavity 110; on the other hand, the shape of the accommodating cavity 110 can also be used to plasticize the packaging bag g2, that is, in the process of placing the packaging bag g2 from the bottom of the accommodating cavity 110 upward into the accommodating cavity 110, the gradually contracted area of ​​the inner wall of the accommodating cavity 110 can squeeze the outer wall of the packaging bag g2, so that the opening at the top of the packaging bag g2 can be gradually squeezed and expanded during the placement process, for example Figure 4 and Figure 5 In the embodiment, the inner wall of the accommodating cavity 110 away from the clamping member 200 is gradually contracted. When the packaging bag g2 is placed upward from the bottom of the accommodating cavity 110, the inner wall gradually squeezes the outer wall of the packaging bag g2 away from the clamping member 200, thereby deforming the opening at the top of the packaging bag g2 and gradually widening the width of the opening to finally reach Figure 2 The effect of display.

[0043] In some embodiments, see Figure 4 and Figure 6 A strip groove 111 communicating with the accommodating cavity 110 is provided on the side of the accommodating cavity 110 for the side edge of one side of the packaging bag g2 to be inserted into the strip groove 111.

[0044] For further information, see Figure 3 The clamping member 200 is provided with a clamping block 210. Preferably, the clamping block 210 is arranged on the end side of the vertical plate 220. Figure 6 Corresponding to the clamping block 210, the shell 100 is provided with an avoidance opening 120 on one side wall of the strip groove 111. When the clamping member 200 is in the first position state, the clamping block 210 is inserted into the avoidance opening 120 and is close to or pressed against the other side wall of the strip groove 111, so as to achieve the purpose of clamping the side of the packaging bag g2 placed in the strip groove 111.

[0045] Preferably, a sloped guide surface is provided at the bottom of the strip groove 111 to facilitate the side edge of the packaging bag g2 to smoothly enter the strip groove 111 .

[0046] Preferably, as in the embodiment shown in the figure, one strip groove 111 is correspondingly provided with two of the clamping blocks 210, and the two clamping blocks 210 are arranged one above and one below with an interval, and the two clamping blocks 210 can be respectively inserted into the avoidance opening 120 provided on the side wall of the strip groove 111, thereby improving the stability when clamping the side of the packaging bag g2.

[0047] In order to improve work efficiency, two packaging bags g2 can be filled with materials at the same time. Figure 1 , Figure 2 and Figure 4 The number of the accommodating cavities 110 is set to two, and the two accommodating cavities 110 are formed side by side on the housing 100. Therefore, during operation, the housing 100 can carry two packaging bags g2 at the same time, and when moving to the corresponding work station, materials can be poured into the two packaging bags g2 at one time, thereby improving work efficiency.

[0048] Based on the above structure with two accommodating chambers 110, the guide rod 400, the elastic member 300 and the clamping member 200 can be arranged as follows: Figure 2 The two strip grooves 111 are respectively formed by two flat sandwich structures 130, and the guide rod 400 passes through one of the sandwich structures 130 horizontally and then abuts against the outer wall of the other sandwich structure 130. At the same time, the guide rod 400 is fastened to the sandwich structure 130 by screws or other fasteners; see Figure 2 and Figure 6The elastic member 300 is sleeved on the guide rod 400 between the two sandwich structures 130, one end of the elastic member 300 is against the outer wall of one of the sandwich structures 130, and the other end is against one of the vertical plates 220 of the clamping member 200; two clamping blocks 210 are respectively provided on the end sides of the two vertical plates 220 of the clamping member 200, and the two clamping blocks 210 correspond to the two avoidance openings 120 provided on the wall of the same sandwich structure 130.

[0049] In the present invention, the packaging bag g2 can be placed into the accommodating cavity 110 from the bottom of the accommodating cavity 110. The operation flow during placement is as follows:

[0050] In the initial state, under the action of the elastic member 300, the clamping member 200 is in the first position state;

[0051] Before insertion, a force is applied to the force plate 230 of the clamping member 200 by a pushing mechanism located beside the housing 100, so that the clamping member 200 switches from the first position state to the second position state; during this process, the clamping block 210 of the clamping member 200 will be separated from the avoidance opening 120, so that the strip groove 111 is unobstructed;

[0052] Subsequently, the packaging bag g2 with an open top and closed bottom and sides is placed into the accommodating cavity 110 from the bottom of the accommodating cavity 110 by the bag-making mechanism at the bottom of the housing 100; during the placement process, the side edge of the packaging bag g2 enters the strip groove 111 on the side of the accommodating cavity 110 and moves upward along the strip groove 111;

[0053] After being inserted into place, the pushing mechanism is allowed to release the force applied to the force-bearing plate 230; after the release, under the action of the elastic member 300, the clamping member 200 will automatically switch to the first position state. During this process, the clamping block 210 of the clamping member 200 will be inserted into the avoidance opening 120 and press the side of the packaging bag g2 located in the strip groove 111, so that the packaging bag g2 placed in the accommodating cavity 110 is clamped and will not fall out of the accommodating cavity 110.

[0054] After loading is completed, when the packaging bag g2 needs to be removed from the bottom of the accommodating chamber 110, the pushing mechanism can again apply force to the force plate 230 of the clamping member 200 to switch the clamping member 200 to the second position state. Then, under the action of gravity and / or other external forces, the packaging bag g2 can leave the bottom of the accommodating chamber 110.

[0055] In addition, the utility model further provides a carrier box conveying mechanism for driving the packaging bag to move in a circular path, and the carrier box conveying mechanism is provided with a plurality of the packaging bag carrying devices described above arranged at intervals in the circumferential direction.

[0056] Secondly, the utility model also provides a Chinese medicine formula granule dispensing device, which is provided with the above-mentioned carrier box conveying mechanism.
