Description

Technical Field

[0001] This utility model relates to the field of angle technology, and in particular to a soft bag sealing clamp and a soft bag material handling system. Background Technology

[0002] Existing flexible bag packaging products on the market require the bag to be cut open and the contents poured out or taken directly. For this type of bagged product, if it is necessary to connect the bag to an automatic dispensing machine to automatically dispense the material inside, the bag must first be opened and then the opening connected to the automatic dispensing machine. In this process, the existing bag sealing clamps cannot guarantee that the material inside the bag remains sealed at all times, resulting in the material inside the bag coming into contact with air, shortening the shelf life of the material inside the bag, and affecting the usage cost of the material inside the bag. In addition, the existing clamps are single-layer structures, which cannot conveniently connect to the automatic dispensing machine while clamping the flexible bag. Utility Model Content

[0003] Based on this, a soft bag sealing clamp and a soft bag material handling system are provided to solve the problem in the prior art that when materials are opened for handling, the materials inside the soft bag will be exposed to the outside world, resulting in material contamination.

[0004] On one hand, this utility model provides a soft bag sealing clamp, which is used to seal the soft bag while connecting the bag mouth. The clamp includes:

[0005] The clamping part has a first clip, which is located at one or both ends of the clamping part.

[0006] The first movable part has one end rotatably connected to the clamping part, and the other end of the first movable part has a second clip, which forms a snap-fit ​​structure with the first clip.

[0007] The second movable part has one end rotatably connected to the clamping part, and the other end of the second movable part has a third clip, which forms a snap-fit ​​structure with the first clip and clamps the soft bag.

[0008] The receiving part is ring-shaped and used to secure the outer periphery of the bag mouth. The receiving part is formed by the clamping part and the first movable part being closed together.

[0009] The first movable part and the second movable part are arranged side by side; the first movable part and the second movable part are connected to the same end of the clamping part, or the first movable part and the second movable part are respectively connected to the two ends of the clamping part.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] In one implementation, the first clip has a first movable part and a second movable part connected to the same end of the clamping part.

[0012] In one implementation, the first clip extends in the direction away from the thickness of the clamping part, and the first clip is L-shaped and has a reverse hook structure.

[0013] Both the second and third clips are slanted structures with a reduced thickness on one side near the clamping part.

[0014] In one implementation, the receiving portion is symmetrically arranged between the clamping portion and the first movable portion.

[0015] In one implementation, the receiving part is a flat hole located in the middle of the clamp's length direction, and the middle parts of both the clamping part and the first movable part are arc-shaped and bulge outward in the direction away from the receiving part.

[0016] In one implementation, the fixture also includes:

[0017] A hinge shaft is located at one end of the clamp, and both the first movable part and the second movable part are rotatably connected to the clamping part via the hinge shaft.

[0018] In one implementation, the fixture also includes:

[0019] The first sealing strip is used to press the bag mouth. The clamping part and the first movable part are fixed with opposing first sealing strips. The first sealing strip extends along the length direction of the clamp.

[0020] The second sealing strip is used to compress the soft bag, and at least one of the contact surfaces of the clamping part and the second movable part is fixed with the second sealing strip.

[0021] In one of the implementation methods,

[0022] The first and second sealing strips are arranged in parallel.

[0023] Two first sealing strips are fixed to the clamping part and the first movable part respectively;

[0024] The second sealing strip is one and fixed on the clamping part, and the second sealing strip is arranged along the length direction of the clamp.

[0025] On the other hand, this utility model also provides a soft bag dispensing system, including a soft bag sealing clamp, and the system further includes:

[0026] The bag mouth is designed to fit into and be clamped by the receiving part; the bag mouth is a hollow cylindrical structure.

[0027] Soft bags are used to hold materials, and the bag spout is used to snap into the open end of the soft bag and serve as a channel for material to be discharged.

[0028] The material handling machine has a material handling port connected to the bag mouth, forming a channel for material discharge and handling.

[0029] In one implementation, the soft bag includes:

[0030] The main body is used to hold materials;

[0031] The outlet section is used for the insertion of the bag mouth and the discharge of materials. The outlet section is connected to the upper side of the main body. When the outlet section is bulging, it is a regular columnar channel.

[0032] The beneficial effects of this utility model are as follows: Since the first movable part and the clamping part can be opened and closed independently and used to clamp the bag mouth, and the second movable part and the clamping part can be opened and closed independently and used to compress the soft bag, when taking out the items in the soft bag, the soft bag can be compressed first by the clamping of the second movable part and the receiving part to prevent the material inside the soft bag from being exposed. Then, the upper part of the soft bag is cut open, and then the bag mouth is clamped into the upper part of the soft bag from the receiving part. The bag mouth is compressed by the first movable part and the clamping part. Then, the bag mouth is connected to the corresponding taking device. When discharging the material, the second movable part and the receiving part are opened, while the clamping state of the first movable part and the clamping part is maintained to compress the bag mouth, so that the material can be discharged through the bag mouth. This achieves the effect of taking out the material in the soft bag while sealing and protecting the material, so as to avoid the material inside the soft bag being contaminated due to opening and effectively reduce the contact between the material and the air, which is conducive to improving the service life of the material inside the soft bag and reducing the contamination and loss of the material.

[0046] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit the scope of this application. It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show components related to this utility model and are not drawn according to the actual number, shape, and size of the components. In actual implementation, the shape, quantity, and proportion of each component can be arbitrarily changed, and the component layout may also be more complex.

[0047] A soft bag sealing clamp, see Figures 1 to 3 The clamp is used to seal the soft bag 70 while connecting the bag mouth 80. The clamp includes a clamping part 10, a first movable part 20, a second movable part 30, and a receiving part 40. The clamping part 10 has a first clip 11, which is provided at one or both ends of the clamping part 10. One end of the first movable part 20 is rotatably connected to the clamping part 10, and the other end of the first movable part 20 has a second clip 21, which forms a snap-fit ​​structure with the first clip 11. One end of the second movable part 30 is rotatably connected to the clamping part 10. The second movable part 30 has a third clip 31 at the other end, which forms a snap-fit ​​structure with the first clip 11 and clamps the soft bag 70; the receiving part 40 is annular and is used to clamp the outer periphery of the bag mouth 80. The receiving part 40 is formed by the clamping part 10 and the first movable part 20 after they are closed together; the first movable part 20 and the second movable part 30 are arranged side by side; the first movable part 20 and the second movable part 30 are connected to the same end of the clamping part 10, or the first movable part 20 and the second movable part 30 are respectively connected to the two ends of the clamping part 10.

[0048] Using the above scheme, see [link / reference] Figures 1 to 3Since the first movable part 20 and the clamping part 10 can be opened and closed independently to clamp the bag mouth 80, and the second movable part 30 and the clamping part 10 can be opened and closed independently to compress the soft bag 70, when taking items from the soft bag 70, the soft bag 70 can first be compressed by the engagement of the second movable part 30 and the receiving part 40 to prevent the material inside the soft bag 70 from being exposed. Then, the upper part of the soft bag 70 is cut open, and the bag mouth 80 is inserted from the receiving part 40 into the upper part of the soft bag 70, and the bag mouth 80 is compressed by the first movable part 20 and the clamping part 10. Then, it is connected to the corresponding dispensing device through the bag mouth 80. When dispensing materials, the second movable part 30 and the receiving part 40 are opened, while the first movable part 20 and the clamping part 10 are kept in a clamped state to press the bag mouth 80, so that the materials can be discharged through the bag mouth 80. This realizes the dispensing of materials in the soft bag 70 while also achieving the effect of sealing and protecting the materials, so as to avoid the materials in the soft bag 70 from being contaminated due to opening and effectively reduce the contact between the materials and the air, which helps to extend the service life of the materials in the soft bag 70 and reduce the contamination and loss of materials.

[0049] In a specific embodiment, see Figures 1 to 3 The first clip 11 may be one or two. When there is one first clip 11, it is located at one end of the clamping part 10. The second clip 21 and the first clip 11 form a repeatedly opening and closing latching structure, and the third clip 31 and the first clip 11 form a repeatedly opening and closing latching structure. When there are two first clips 11, they may be located on one side of the clamping part 10 or on both sides of the clamping part 10. When the two first clips 11 are located on one side of the clamping part 10, the second clip 21 and the third clip 31 form a repeatedly opening and closing latching structure. The clips 31 form detachable snap-fit ​​structures with different first clips 11 arranged side by side; when the two first clips 11 are located on both sides of the clamping part 10, the second clips 21 and the third clips 31 are detachably snap-fit ​​connected to the different first clips 11 located on both sides of the clamping part 10. The opening directions of the first movable part 20 and the second movable part 30 are opposite, which reduces the impact of opening the first movable part 20 or the second movable part 30 alone on the other, and avoids the situation where two movable parts are accidentally opened when only one movable part needs to be opened.

[0050] In a specific embodiment, the receiving part 40 is annular, that is, the receiving part 40 is a closed annular structure. The shape of the receiving part 40 is not specifically limited. For example, the receiving part 40 can be a round hole, a flat hole, an elliptical hole, or a square hole, a rhomboid hole, etc.

[0051] In some embodiments of this application, see Figures 1 to 3The first clip 11 has one part, and the first movable part 20 and the second movable part 30 are connected to the same end of the clamping part 10. In this way, by setting a first clip 11, the structure of the clamp is simplified, and the first movable part 20 and the second movable part 30 are rotatably connected to the clamping part 10 in the same direction, which is beneficial to improving the opening and closing speed of the first movable part 20 and the second movable part 30.

[0052] In some embodiments of this application, see Figures 1 to 3 The first clip 11 extends in the direction away from the thickness of the clamping part 10. The first clip 11 is L-shaped and has a reverse hook structure. The second clip 21 and the third clip 31 are both oblique structures with a reduced thickness on the side close to the clamping part 10. In this way, the first clip 11 extends outward and protrudes to connect with the second clip 21 and the third clip 31 to form a snap-fit ​​structure. The first clip 11 has an L-shaped snap-fit ​​structure, and the ends of the second clip 21 and the third clip 31 are obliquely thinned to facilitate end deformation and snapping into the first clip 11, thereby facilitating the connection of the snap-fit ​​structure.

[0053] In some embodiments of this application, see Figures 1 to 3 The receiving portion 40 is symmetrically arranged between the clamping portion 10 and the first movable portion 20. In this way, the symmetrical arrangement of the receiving portion 40 facilitates the clamping and fixing of the annular bag mouth 80, which is conducive to forming a seal on the outer periphery of the bag mouth 80. In addition, the symmetrical structure distributes the force evenly, which helps to improve the service life of the clamping portion 10 and the first movable portion 20.

[0054] In some embodiments of this application, see Figures 1 to 3 The receiving portion 40 is a flat hole located in the middle of the clamp's length direction. The middle portions of the clamping portion 10 and the first movable portion 20 are both arc-shaped and protrude outwards in the direction away from the receiving portion 40. This central location of the receiving portion 40 facilitates clamping. By making the receiving portion 40 an arc-shaped structure with a protruding middle portion, the thickness at both ends of the clamp's length direction is reduced, which helps to reduce the clamp's weight and save material. The flat hole design of the receiving portion 40, symmetrically positioned between the clamping portion 10 and the first movable portion 20, facilitates the rotational opening and locking of the first movable portion 20, preventing the upper half of the receiving portion 40's outline from affecting its locking or opening, thus reducing jamming issues when the receiving portion 40 is opened or locked.

[0055] In a specific embodiment, both the first movable part 20 and the clamping part 10 have the outline of half of the receiving part 40. The half outline of the receiving part 40 has two edges, each of which is a bevel, in order to reduce the interference of the receiving part 40 with the bag mouth 80 when it is opened or closed, and to reduce the jamming problem when the receiving part 40 is opened or locked.

[0056] In some embodiments of this application, see Figures 1 to 3 The clamp also includes a hinge shaft 50, which is located at one end of the clamp. The first movable part 20 and the second movable part 30 are both rotatably connected to the clamping part 10 via the hinge shaft 50. This hinge shaft 50 facilitates the rotatable connection of the first movable part 20 and the second movable part 30 to the clamping part 10, allowing the first movable part 20 and the second movable part 30 to rotate and engage or disengage with the clamping part 10, thus facilitating changes in the usage state of the first movable part 20 and the second movable part 30.

[0057] In a specific embodiment, the hinge shaft 50 can be part of the clamping part 10. By providing the hinge shaft 50 at the end of the clamping part 10, the first movable part 20 and the second movable part 30 can be connected. Corresponding clearances can be provided at both ends of the hinge shaft 50, so that the first movable part 20 and the second movable part 30 are respectively connected to the two ends of the hinge shaft 50, thereby realizing the connection between the first movable part 20 and the second movable part 30 and the hinge shaft 50. The hinge shaft 50 can also be an independent workpiece, so that the hinge shaft 50 and the clamping part 10 do not rotate relative to each other, or the clamping part 10 and the hinge shaft 50 can rotate relative to each other.

[0058] In some embodiments of this application, see Figures 1 to 3 The clamp also includes a first sealing strip 61 and a second sealing strip 62. The first sealing strip 61 is used to press the bag mouth 80. The first sealing strip 61 is fixed on the contact surface of the clamping part 10 and the first movable part 20, and the first sealing strip 61 extends along the length direction of the clamp. The second sealing strip 62 is used to press the soft bag 70. At least one of the contact surfaces of the clamping part 10 and the second movable part 30 is fixed with a second sealing strip 62. In this way, by setting a first sealing strip 61 on the clamp to clamp the bag mouth 80, the leakage of air in the circumference between the soft bag 70 and the bag mouth 80 is reduced, thereby improving the sealing of the material inside the soft bag 70. When setting it, since the bag mouth 80 needs to extend into the receiving part 40, the outer periphery of the bag mouth 80 will simultaneously abut against the inner wall of the clamping part 10 and the first movable part 20. This application also sets a corresponding first sealing strip 61 on the abutting surface of the clamping part 10 and the first movable part 20 to ensure the sealing of the outer periphery of the bag mouth 80, thereby improving the sealing of the material inside the soft bag 70. By setting a second sealing strip 62 on the clamp to seal the soft bag 70, the lower part of the soft bag 70 is sealed, that is, the material inside the soft bag 70 is sealed before the soft bag 70 is opened, preventing the material inside the soft bag 70 from being exposed or exposed to air after the soft bag 70 is opened, thus protecting the material.

[0059] In a specific embodiment, since the soft bag 70 is a soft structure, connecting the second sealing strip 62 to only one of the contact surfaces between the clamping part 10 and the second movable part 30 is sufficient to achieve a sealing effect on the soft bag 70. Optionally, the corresponding second sealing strip 62 can be connected to both of the contact surfaces between the clamping part 10 and the second movable part 30 to achieve a compression and sealing effect on the soft bag 70. The second sealing strip 62 can be provided in one or more layers. When multiple layers of second sealing strip 62 are provided, the sealing effect is relatively better. The specific number of layers of second sealing strip 62 to be provided depends on the specific application scenario and sealing requirements.

[0060] In some embodiments of this application, see Figures 1 to 3 The first sealing strip 61 and the second sealing strip 62 are arranged in parallel; two first sealing strips 61 are fixed on the clamping part 10 and the first movable part 20 respectively; one second sealing strip 62 is fixed on the clamping part 10 and the second sealing strip 62 is arranged along the length direction of the clamp. In this way, the first sealing strip 61 and the second sealing strip 62 are arranged in parallel and seal the corresponding positions of the soft bag 70 in the same direction, which facilitates the setting and arrangement of the sealing strips and also facilitates the sealing of the material along the material discharge direction. The setting of multiple first sealing strips 61 makes the circumferential of the receiving part 40 formed by the clamping part 10 and the first movable part 20 have multiple layers of sealing strips, thereby improving the sealing effect of the receiving part 40 on the bag mouth 80 and preventing air leakage in the circumferential direction of the bag mouth 80. Since the second sealing strip 62 is used to press the soft bag 70, only one second sealing strip 62 is needed to press and seal the soft bag 70. When setting the position of the second sealing strip 62, it can be set on the clamping part 10 or on the second movable part 30.

[0061] In a specific embodiment, when there are four first sealing strips 61 on the inner wall of the clamping part 10, since two first sealing strips 61 are located on the inner wall of one half of the sealing part and two first sealing strips 61 are located on the inner wall of the other half of the sealing part, the two sets of first sealing strips 61 corresponding to each other can form two closed ring structures, thereby forming two closed sealing structures in the axial direction of the bag mouth 80 to improve the sealing effect of the bag mouth 80.

[0062] A soft bag dispensing system, see Figure 4 and Figure 5 The system includes a soft bag sealing clamp, a bag nozzle 80, a soft bag 70, and a material handling machine. The bag nozzle 80 is fitted with and clamped by the receiving part 40. The bag nozzle 80 is a hollow cylindrical structure. The soft bag 70 is used to hold materials, and the bag nozzle 80 is used to snap into the open end of the soft bag 70 and serve as a channel for material discharge. The material handling machine's discharge port is connected to the bag nozzle 80 to form a channel for material discharge and retrieval.

[0063] When using the material handling system, see Figure 4 and Figure 5 The material inside the soft bag 70 is squeezed out from the upper part of the soft bag 70, corresponding to the end to be opened, so that the material is concentrated in the lower part of the soft bag 70. The soft bag feeding system clamps the soft bag 70 with the set clamps, so that the end of the soft bag 70 to be opened is clamped by the third clip 31 and the first clip 11 between the clamping part 10 and the second movable part 30. The opening end of the soft bag 70 is cut open, so that the first movable part 20 and the clamping part 10 are in the open state, and the corresponding second clip 21 and the first clip 11 are released. The bag mouth 80 is inserted into the opening end and closed. The first movable part 20 and the clamping part 10 press one end of the bag mouth 80 into the receiving part 40 by the first sealing strip 61; the other end of the bag mouth 80 is connected to the feeding machine, and the second movable part 30 and the clamping part 10 are opened, that is, the third clip 31 and the first clip 11 are opened, so that the material in the soft bag 70 can enter the feeding machine through the bag mouth 80 or be discharged through the feeding machine. Thus, when the material in the soft bag 70 is taken out, the material at the opening of the soft bag 70 is avoided, the contact between the material and the air is reduced, and the contamination of the material is avoided.

[0064] In some embodiments of this application, see Figure 4 and Figure 5 The soft bag 70 includes a main body 71 and a discharge section 72. The main body 71 is used to hold materials; the discharge section 72 is used for the insertion of the bag mouth 80 and for discharging materials. The discharge section 72 is connected to the upper side of the main body 71, and when bulging, it forms a regular columnar channel. Thus, by providing the main body 71 and discharge section 72 to the soft bag 70, the main body 71 is used to collect materials. Before the soft bag 70 is opened, the materials are gathered into the main body 71, and then clamped by a fixture, which is positioned at the discharge section 72. By providing a corresponding columnar channel at the discharge section 72, it is convenient to discharge materials and to insert and fix the bag mouth 80, thereby improving the overall efficiency of the material handling system.
