Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0037] In the description of the utility model, it needs to explain, unless otherwise expressly provided and limited, the terms "mounting", "connecting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected, it can be mechanical connection, or electrical connection, it can be directly connected, or indirectly connected through intermediate medium, it can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0038] The specific embodiments of the utility model are described in detail below in combination with the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the utility model, and not used to limit the utility model.

[0039] The embodiment of the utility model provides a kind of bagging device, as shown in Figure 1 And Figure 2 It includes first drive mechanism 1, support platform 2 and multiple bagging plates 4, first drive mechanism 1 is connected with support platform 2, first drive mechanism 1 is configured to drive support platform 2 reciprocating motion along horizontal direction, one end of each bagging plate 4 is installed in support platform 2 in turn along the direction perpendicular to support platform 2 movement, and the distance between any two bagging plates 4 is configured to be adjustable.

[0040] The working process of the above-mentioned bagging device is specifically described by taking two bagging plates 4 as an example:

[0041] In use, as shown in Figure 1 First drive mechanism 1 can drive support platform 2 and the two bagging plates 4 on support platform 2 to move forward and extend into bag body 3, by adjusting the distance between the two bagging plates 4 in bag body 3 through left and right movement, the bagging plate 4 can be flattened to open the bag body, so that the opening of the bag body is kept flat during hot pressing, so that the packaging line is more flat, and there is no wrinkle, reduces even avoids the phenomenon that bag body exists leakage due to packaging failure.

[0042] When there are two or more bag-strapping plates 4, the shapes of each bag-strapping plate 4 can be different to accommodate bags 3 of different specifications and materials. When in use, two suitable bag-strapping plates 4 can be selected to extend into the bag 3 to flatten the bag 3.

[0043] It should be noted that any structure that can drive the support platform 2 to reciprocate in the direction of approaching or moving away from the bag body 3 can be the first drive mechanism 1 mentioned in the above embodiments. For example, the first drive mechanism 1 can include an electric cylinder, a linear motor, etc. that perform linear motion, or it can be a combination of a drive component that performs rotational motion and a transmission component. The transmission component can convert rotational motion into linear motion. The transmission component can be, but is not limited to, a crank-slider assembly, a lead screw-nut assembly, etc.

[0044] In a preferred embodiment, such as Figure 1 As shown, the first drive mechanism 1 includes an electric cylinder. The cylinder body is mounted on the base plate of the main support 10. The movable end of the electric cylinder is connected to the support platform 2. The base plate is provided with a first slide rail 101. The support platform 2 slides in cooperation with the first slide rail 101 through a slider. The first slide rail 101 can guide the movement of the support platform 2 relative to the bag body 3.

[0045] Specifically, the first slide rail 101 can be configured as two.

[0046] In alternative implementations, such as Figure 1 As shown, the plurality of bag-strapping plates 4 include a first bag-strapping plate 41 and a second bag-strapping plate 42. The support platform 2 is provided with a second drive mechanism 5 connected to at least one of the first bag-strapping plate 41 and the second bag-strapping plate 42. The second drive mechanism 5 is configured to drive the first bag-strapping plate 41 and / or the second bag-strapping plate 42 connected thereto to move in a direction perpendicular to the movement of the support platform 2.

[0047] The second drive mechanism 5 enables automatic adjustment of the distance between the first bag-strapping plate 41 and the second bag-strapping plate 42, thereby improving sealing efficiency and reducing manual workload.

[0048] When the first bag-strapping plate 41 or the second bag-strapping plate 42 is connected to the second drive mechanism 5, the second drive mechanism 5 can drive one of the connected parts to move away from or closer to the other, so as to adjust the distance between the first bag-strapping plate 41 and the second bag-strapping plate 42, thereby opening the bag body 3 and releasing the bag body 3.

[0049] When both the first bag-strapping plate 41 and the second bag-strapping plate 42 are connected to the second drive mechanism 5, the first bag-strapping plate 41 and the second bag-strapping plate 42 move in opposite directions. This method can accelerate the adjustment of the distance between the first bag-strapping plate 41 and the second bag-strapping plate 42, thereby increasing the rate at which the bag body 3 is flattened.

[0050] The second driving mechanism 5 can include an electric cylinder, and when the first and second bagging plates 41 and 42 are connected to the second driving mechanism 5, the electric cylinder can be configured as two, which are connected to the first and second bagging plates 41 and 42, respectively.

[0051] As shown in Figure 1 , the second driving mechanism 5 can also include a power source 51 and a lead screw 52.

[0052] Specifically, as shown in Figure 3 and Figure 4 , the support platform 2 is provided with a support 21, and the power source 51 is mounted on the support 21. The power source 51 is connected to the lead screw 52 and configured to drive the lead screw 52 to rotate relative to the support platform 2. The rotation axis of the lead screw 52 is parallel to the top surface of the support platform 2. The first and second bagging plates 41 and 42 are threadedly connected to the lead screw 52 and are slidingly connected to the support platform 2 in a direction perpendicular to the movement of the support platform 2.

[0053] In use, the power source 51 drives the lead screw 52 to rotate. Since the first and second bagging plates 41 and 42 are threadedly connected to the lead screw 52 and are slidingly connected to the support platform 2 in a direction perpendicular to the movement of the support platform 2, the rotation of the lead screw 52 can realize the opposite movement and the opposite movement of the first and second bagging plates 41 and 42.

[0054] It can be understood that in order to make the moving direction of the first and second bagging plates 41 and 42 opposite, the rotation direction of the thread on the lead screw 52 matched with the first bagging plate 41 is opposite to that of the thread on the lead screw 52 matched with the second bagging plate 42.

[0055] The above-mentioned second driving mechanism 5 adopts the cooperation mode of the power source 51 and the lead screw 52. By using one power source 51, the movement of the first and second bagging plates 41 and 42 can be realized. The cooperation mode of the thread can also ensure the movement accuracy of the first and second bagging plates 41 and 42.

[0056] The above-mentioned power source 51 can adopt an electric motor. In order to reduce the area occupied by the second driving mechanism 5 along the axial direction of the lead screw 52, as shown in Figure 4 , the power source 51 includes an electric motor 511 and a transmission assembly 512. The transmission assembly 512 can be a gear transmission assembly, a belt transmission assembly or a chain transmission assembly, etc.

[0057] Taking the belt transmission assembly as an example, the belt transmission assembly includes a driving wheel connected to the power output shaft of the electric motor 511, a driven wheel connected to the lead screw 52, and a belt wound between the driving wheel and the driven wheel. When the electric motor 511 rotates, it can drive the driving wheel to rotate, and through the transmission of the belt, it can drive the driven wheel and the lead screw 52 connected to the driven wheel to rotate.

[0058] like Figure 4 As shown, the motor 511 and the lead screw 52 are located on the same side of the support 21, and the transmission assembly 512 is located on the other side of the support 21, which can effectively reduce the area occupied by the second drive mechanism 5 along the axial direction of the lead screw 52.

[0059] In alternative implementations, such as Figure 3 As shown, both the first bag-strapping plate 41 and the second bag-strapping plate 42 have a sliding seat 44. The sliding seat 44 is threadedly engaged with the lead screw 52 and also slidably engaged with the second slide rail 22 on the support platform 2. The second slide rail 22 extends horizontally and is perpendicular to the direction in which the first drive mechanism 1 drives the support platform 2 to move, so that when the lead screw 52 rotates, it can stably drive the first bag-strapping plate 41 and the second bag-strapping plate 42 to move towards or away from each other.

[0060] The plates used to open the bag body 3 in the first bag-strapping plate 41 and the second bag-strapping plate 42 can be detachably connected to their respective sliding seats 44 by screws. The plates can be provided with waist-shaped grooves along the direction in which the first drive mechanism 1 drives the support platform 2 to move, so that the position of the plates relative to the sliding seats 44 is adjustable.

[0061] In alternative implementations, such as Figure 5 and Figure 6 As shown, in any two adjacent bag-straightening plates 4, the edges of the two bag-straightening plates 4 that are facing away from each other have narrowed portions 43.

[0062] by Figure 6 For example, the first bag-strapping plate 41 has a narrowed portion 43 at its edge away from the second bag-strapping plate 42, and the thickness of the narrowed portion 43 is smaller the closer it is to the side end face of the first bag-strapping plate 41; the second bag-strapping plate 42 has a narrowed portion 43 at its edge away from the first bag-strapping plate 41, and the thickness of the narrowed portion 43 is smaller the closer it is to the side end face of the second bag-strapping plate 42.

[0063] The above method allows the thickness of the bag-strapping plate 4 used to flatten the edge of the bag body 3 to be thinner as it gets closer to the bag body 3. When the bag body 3 is opened, the two ends of the side of the bag body 3 can gradually form a gap towards the middle through the bag-strapping plate 4, which facilitates vacuuming.

[0064] A second aspect of this utility model provides a packaging device, which includes the aforementioned bag-rolling device.

[0065] The packaging device provided in the second aspect of this utility model includes the bag-strapping device provided in the first aspect of this utility model, thereby having all the beneficial effects of the bag-strapping device provided in the first aspect of this utility model.

[0066] In alternative implementations, such as Figure 4As shown, the packaging equipment also includes a clamping mechanism 6 mounted on the support platform 2. The clamping mechanism 6 is distributed on both sides of a plurality of bag-strapping plates 4 in a direction perpendicular to the movement of the support platform 2. The clamping mechanism 6 is configured to clamp the edge of the bag body 3.

[0067] When in use, after the bag-straightening plate 4 flattens the bag body 3, the clamping mechanism 6 can clamp the bag edge opened by the bag-straightening plate 4 from the outside of the bag body 3, leaving a gap through the thickness of the bag-straightening plate 4, and then perform vacuuming.

[0068] In the above embodiments, the packaging equipment adds a clamping mechanism 6 to the design of the bag-strapping plate 4. The clamping mechanism 6 can clamp the edges of the bag body 3 onto the bag-strapping plate 4 from both sides of the bag body 3, ensuring the stability of the edges of the bag body 3 relative to the bag-strapping plate 4. During the vacuuming process, the edges of the bag body 3 are not easy to detach from the bag-strapping plate 4.

[0069] The clamping mechanism 6 may include two, three, four or even more clamping components.

[0070] When the clamping mechanism 6 includes two clamping components, each clamping component can clamp one side of the bag body 3. When the clamping mechanism 6 includes more than two clamping components, each side of the bag body 3 can be clamped by at least one clamping component, thereby ensuring that each side of the bag body 3 can be stably pressed against the bag-strapping plate 4. When one side is clamped by multiple clamping components, the clamping positions can be distributed from the open end of the bag body towards the end of the bag body 3 away from the open end.

[0071] For example Figure 4 For example, the clamping mechanism 6 includes a first clamping component 61 located on one side of the plurality of bag-strapping plates 4 and a second clamping component 62 located on the other side of the plurality of bag-strapping plates 4. At least one of the first clamping component 61 and the second clamping component 62 is slidably engaged with the second slide rail 22 so that its position is adjustable in the direction perpendicular to the movement of the support platform 2.

[0072] The above-described embodiments enable the clamping mechanism 6 to adapt to bags 3 with different opening widths and accurately clamp the edges of the bag 3.

[0073] In an optional embodiment, the packaging device further includes a third drive mechanism 011, at least one of the first clamping component 61 and the second clamping component 62 being connected to the third drive mechanism 011. The third drive mechanism 011 is configured to drive the first clamping component 61 and / or the second clamping component 62 connected thereto to slide relative to the second slide rail 22, so that the clamping mechanism 6 can automatically adapt to bags 3 with different opening widths.

[0074] by Figure 4For example, the first clamping assembly 61 and the second clamping assembly 62 are connected with the third driving mechanism 011, and the moving directions of the first clamping assembly 61 and the second clamping assembly 62 are opposite. The above manner can accelerate the adjustment of the distance between the first clamping assembly 61 and the second clamping assembly 62, thereby increasing the speed of clamping the edge of the bag body 3.

[0075] The third driving mechanism 011 can include an electric cylinder, a linear motor, or the like for linear motion, or a combination of a driving member for rotary motion, such as a motor, and a transmission assembly capable of converting rotary motion into linear motion. The transmission assembly can be, but is not limited to, a crank slider assembly, a screw nut assembly, or the like.

[0076] Specifically, as shown in Figure 5 each clamping assembly includes an upper clamping jaw 611 and a lower clamping jaw 612, which can be clamped at the narrowing portion 43 during use.

[0077] In an optional embodiment, as shown in Figure 7 the upper clamping jaw 611 and the lower clamping jaw 612 each include an extension portion 6111 and a clamping portion 6112 connected at an angle to the extension portion 6111. The extension direction of the extension portion 6111 is parallel to the movement direction of the support platform 2, and the clamping portion 6112 is configured to clamp the edge of the bag body 3.

[0078] In the above embodiment, since the clamping portion 6112 is connected at an angle to the extension portion 6111, it is convenient for the user to observe the position of the edge of the bag body 3 clamped by the clamping portion 6112.

[0079] The surface of the clamping portion 6112 for clamping the bag body 3 can be provided with clamping blocks, which can be clamped at the narrowing portion 43, so that the force of the clamping portion 6112 acting on the edge of the bag body 3 is more concentrated.

[0080] In an optional embodiment, as shown in Figure 7 the clamping assembly includes a lifting structure 613 mounted on the support platform 2, and at least one of the upper clamping jaw 611 and the lower clamping jaw 612 is connected with the lifting structure 613 and configured to adjust the clamping force under the driving of the lifting structure 613.

[0081] When the upper clamping jaw 611 or the lower clamping jaw 612 is connected with the lifting structure 613, the lifting structure 613 can drive one of them away from or close to the other, so as to adjust the distance between the upper clamping jaw 611 and the lower clamping jaw 612, thereby adjusting the clamping force.

[0082] When the upper clamping jaw 611 and the lower clamping jaw 612 are connected with the lifting structure 613, the moving directions of the upper clamping jaw 611 and the lower clamping jaw 612 are opposite. The above-mentioned mode can accelerate the adjustment of the distance between the upper clamping jaw 611 and the lower clamping jaw 612, thereby increasing the speed of clamping and releasing the bag body 3 by the clamping mechanism 6.

[0083] The lifting structure 613 can include an electric cylinder, a linear motor, etc. that moves linearly, or a combination of a driving element that rotates and a transmission assembly. The transmission assembly can convert the rotary motion into linear motion, and can but not limited to adopt a crank slider assembly, a screw nut assembly, etc.

[0084] In the preferred embodiment, the lifting structure 613 includes an electric cylinder, the cylinder body is installed on the support platform 2, and the movable end of the electric cylinder is connected with the upper clamping jaw 611 and / or the lower clamping jaw 612.

[0085] Specifically, the lifting structure 613 can be installed on the third driving mechanism 011, the third driving mechanism 011 drives the lifting structure 613 to slide along the second sliding rail 22, and the upper clamping jaw 611 and the lower clamping jaw 612 are connected with the lifting structure 613.

[0086] In the alternative embodiment, as shown in Figure 3 , the packaging device further includes a vacuum pipe 7 installed on the support platform 2, and the vacuum pipe 7 is arranged to be adjustable along the direction parallel to the movement direction of the support platform 2.

[0087] The arrangement of the vacuum pipe 7 can realize the vacuumization of the bag body 3, and at the same time, since the vacuum pipe 7 is arranged to be adjustable along the direction parallel to the movement direction of the support platform 2, after the bag flattening plate 4 flattens the bag body 3, the vacuum pipe 7 can continue to penetrate into the bag body 3, so as to more quickly extract the gas in the bag body 3 during operation.

[0088] The movement of the vacuum pipe 7 can be realized by an electric cylinder, a linear motor, etc.
