Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to a suction conveying mechanism for a packaging machine. Background Technology

[0002] Film packaging machines typically include the following components: bag making, bag feeding, bag opening, material feeding, and sealing. Bag feeding refers to the process of conveying the prepared packaging bags to the front of the bag opening mechanism via a conveying mechanism, and conveying the bagged products to the sealing mechanism.

[0003] Current packaging machines utilize a single suction conveyor belt, which is suitable for conveying bags with flush-edge openings. For example... Figure 1 As shown, Figure 1 A type of packaging bag includes a double-layered bag body. The lower layer of the bag body is connected to a flange with an adhesive strip. After the bag is filled with an object, the flange flips along the flange line, and the adhesive strip seals the flange to the upper layer of the double-layered bag body, thus sealing the bag opening. However, the existing suction conveying mechanism of packaging machines cannot be used to complete this process. Figure 1 The structure of this packaging bag is used for transportation.

[0029] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] In the description of this embodiment, the terms "upper," "lower," "left," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0033] like Figures 2 to 5 As shown, this utility model embodiment provides a suction conveying mechanism for a packaging machine, including: a suction frame 1, on which a first suction conveyor belt 2 and a second suction conveyor belt 3 extending along a first direction X are arranged. A plurality of first suction grooves 11 are arranged below the top of the first suction conveyor belt 2, and a plurality of second suction grooves 12 are arranged below the top of the second suction conveyor belt 3. Both the first suction conveyor belt 2 and the second suction conveyor belt 3 are provided with a plurality of suction holes. The first suction grooves 11 and the second suction grooves 12 are connected. Below the first suction groove 11 is a suction box 13, through which a suction device such as a suction fan is connected to provide suction. The first suction conveyor belt 2 and the second suction conveyor belt 3 are separated by a partition frame 4. The first suction conveyor belt 2 extends from one end of the suction frame 1 to the other end of the suction frame 1, but the second suction conveyor belt 3 only extends from one end of the suction frame 1 to the middle position of the suction frame 1. This is because a sealing structure is set in the rear half of the suction frame 1. The sealing structure requires the packaging bag 7 to be turned up. Therefore, the second suction conveyor belt 3 cannot have suction in the rear half of the suction frame 1.

[0034] This utility model embodiment provides a suction conveying mechanism for a packaging machine, which is divided into a first suction conveyor belt 2 and a second suction conveyor belt 3. The first suction conveyor belt 2 and the second suction conveyor belt 3 correspond to the double-layer bag body and the flange of the packaging bag 7, respectively. The first suction conveyor belt 2 and the second suction conveyor belt 3 rotate synchronously, and can convey synchronously before heat sealing the bag opening to ensure conveying accuracy. They do not affect each other during heat sealing or edge sealing, thus ensuring normal heat sealing or edge sealing.

[0035] like Figures 2 to 5 As shown, one end of the suction frame 1 is provided with a first suction drive shaft 21 and a second suction drive shaft 24. The first suction drive shaft 21 is provided with a first suction drive wheel 211, and the second suction drive shaft 24 is provided with a second suction drive wheel 241. The other end of the suction frame 1 is provided with a first suction follower shaft 22 and a second suction follower shaft 23. The first suction follower shaft 22 is provided with a first suction follower wheel 221, and the second suction follower shaft 23 is provided with a second suction follower wheel 231. The first suction conveyor belt 2 is sequentially wound around the first suction drive wheel 211, the first suction follower wheel 221, the second suction follower wheel 231, and the second suction follower wheel 231. The suction frame 1 is also provided with a suction drive motor 6, and the output end of the suction drive motor 6 is connected to the first suction drive shaft 21. Specifically, the suction frame 1 is further provided with a first tensioning roller 25, a second tensioning roller 26, and a third tensioning roller 27 rotatably mounted. The first tensioning roller 25 is located on the side near the first suction drive shaft 21, the second tensioning roller 26 is located on the side near the second suction follower shaft 23, and the third tensioning roller 27 is located in the middle of the bottom of the suction frame 1. The first tensioning roller 25, the second tensioning roller 26, and the third tensioning roller 27 form a "V" shape, which keeps the first suction conveyor belt 2 taut. In this embodiment of the present invention, the suction drive motor 6 drives the first suction drive shaft 21 to rotate, thereby causing the first suction conveyor belt 2 to rotate and be conveyed on the first suction drive wheel 211, the first tensioning roller 25, the third tensioning roller 27, the second tensioning roller 26, the first suction follower wheel 221, the second suction follower wheel 231, and the second suction follower wheel 231.

[0036] like Figures 2 to 5As shown, the suction frame 1 is also provided with a third suction follower shaft 31 and a fourth suction follower shaft 32. The third suction follower shaft 31 is provided with a third suction follower wheel 311, and the fourth suction follower shaft 32 is provided with a fourth suction follower wheel 321. The first suction follower shaft 22 is also provided with a fifth suction follower wheel 33, and the second suction follower shaft 23 is also provided with a sixth suction follower wheel 34. The second suction conveyor belt 3 passes around the fifth suction follower wheel 33, the sixth suction follower wheel 34, the third suction follower wheel 311, and the fourth suction follower wheel 321 in sequence. Specifically, in this embodiment of the present invention, when the first suction follower shaft 22 rotates, it drives the fifth suction follower wheel 33 to rotate synchronously. When the second suction follower shaft 23 rotates, it drives the sixth suction follower wheel 34 to rotate, thereby driving the second suction conveyor belt 3 to rotate. This makes the first suction conveyor belt 2 and the second suction conveyor belt 3 rotate synchronously. By synchronously driving the first suction conveyor belt 2 and the second suction conveyor belt 3 through a suction drive motor 6, synchronous conveying is effectively guaranteed. When the packaging bag 7 is conveyed on the first suction conveyor belt 2 and the second suction conveyor belt 3, there will be no deviation or tilting.

[0037] like Figure 2 As shown, the output end of the suction drive motor 6 is provided with a first linkage gear 61, and one end of the first suction drive shaft 21 is coaxially provided with a second linkage gear 62. A first linkage belt 63 is sleeved between the first linkage gear 61 and the second linkage gear 62. The suction drive motor 6 drives the first suction drive shaft 21 to rotate through the first linkage gear 61, the first linkage belt 63, and the second linkage gear 62.

[0038] like Figures 2 to 5 As shown, a pressing frame 5 is also provided above the suction frame 1. A pressing component 51 is provided on the pressing frame 5. The connection between the pressing frame 5 and the pressing component 51 is adjustable; that is, the position of the pressing component 51 can be adjusted by adjusting the pressing frame 5. The pressing component 51 includes a pressing conveyor belt 53, which extends along a first direction and is located above the first suction conveyor belt 2. Specifically, in this embodiment, after the packaging bag 7 is filled, the packaging bag 7 containing the items will be conveyed between the pressing conveyor belt 53 and the first suction conveyor belt 2. The pressing conveyor belt 53 flattens the packaged packaging bag 7, ensuring that the bonding position remains flat during subsequent edge-folding and bonding.

[0039] like Figures 2 to 5As shown, the pressing assembly 51 also includes a pressing mounting frame 511. One end of the pressing mounting frame 511 is rotatably equipped with a pressing drive shaft 512, and the other end of the pressing mounting frame 511 is rotatably equipped with a pressing follower shaft 513. A pressing drive wheel 514 is provided on the pressing drive shaft 512, and a pressing follower wheel 515 is provided on the pressing follower shaft 513. The pressing conveyor belt 53 is sleeved between the pressing drive wheel 514 and the pressing follower wheel 515. A pressing connecting frame 516 is provided on the side of the pressing frame 5 near the second linkage gear 62. A fifth follower shaft 517 is rotatably mounted on the pressing connecting frame 516. A fourth linkage gear 518 is coaxially mounted on the side of the fifth follower shaft 517 near the first linkage gear 61. A third linkage gear 519 is also coaxially mounted on the first suction drive shaft 21. A second linkage belt 520 is sleeved between the third linkage gear 519 and the fourth linkage gear 518. The fifth follower shaft 517 passes through the pressing connecting frame 516. A universal coupling (not shown) is provided on the side of the fifth follower shaft 517 away from the fourth linkage gear 518. The universal coupling is connected to the pressing drive shaft 512. Specifically, in this embodiment, the suction drive motor 6 drives the first suction drive shaft 21 to rotate while simultaneously driving the fourth drive gear 518 to rotate via the third linkage gear 519 and the second linkage belt 520. The fourth linkage gear 518 drives the fifth follower shaft 517 to rotate, and the fifth follower shaft 517 drives the pressing drive shaft 512 to rotate via a universal coupling, thereby causing the pressing conveyor belt 53 to rotate synchronously. The pressing conveyor belt 53 rotates synchronously with the first suction conveyor belt 2. The upper layer of the double-layer packaging bag 7 is in contact with the pressing conveyor belt 53, and the lower layer of the double-layer packaging bag 7 is in contact with the first suction conveyor belt 2. Since the pressing conveyor belt 53 and the first suction conveyor belt 2 rotate synchronously, the upper and lower layers of the double-layer packaging bag 7 move synchronously. While flattening the packaging bag 7, the upper and lower sides of the packaging bag 7 will not be misaligned, wrinkled, or damaged.

[0040] like Figure 2 As shown, in order to make the pressing conveyor belt 53 rotate clockwise in coordination with the counterclockwise rotation of the first suction conveyor belt 2, a sixth follower shaft 522 and a seventh follower shaft 523 are respectively provided on the upper and lower sides of the fifth follower shaft 517. A fifth linkage gear 524 is provided on the sixth follower shaft 522, and a sixth linkage gear 525 is provided on the seventh follower shaft 523. The second linkage belt 520 passes around the third linkage gear 519, the sixth linkage gear 525, the fourth linkage gear 518, and the sixth linkage gear 525 in sequence.

[0041] like Figures 2 to 5As shown, the pressing mounting frame 511 includes a first pressing mounting frame 5111 and a second pressing mounting frame 5112. The first pressing mounting frame 5111 and the second pressing mounting frame 5112 are rotatably connected. The pressing drive shaft 512 is disposed on the first pressing mounting frame 5111, and the pressing follower shaft 513 is disposed on the second pressing mounting frame 5112. A third pressing mounting frame 5113 is disposed on the side of the first pressing mounting frame 5111 near the second pressing mounting frame 5112. A pressing cylinder 521 is disposed on the third pressing mounting frame 5113. The pressing cylinder 521 is disposed at an angle downward. A fourth pressing mounting frame 5114 is disposed on the second pressing mounting frame 5112. The output end of the pressing cylinder 521 is connected to the fourth pressing mounting frame 5114. Specifically, in this embodiment, the pressing cylinder 521 can control the second pressing mounting frame 5112 to have an up-and-down swing amplitude. When the packaged bag 7 that has been filled is about to enter the pressing conveyor belt 53, the pressing cylinder 521 is retracted and the second pressing mounting frame 5112 is in a raised state. The packaged bag 7 that has been filled can smoothly enter the pressing conveyor belt 53. After entering, the driving cylinder drives the second pressing mounting frame 5112 to swing and press down, flattening the packaged bag 7 and conveying it at the same time. This cycle repeats.

[0042] like Figure 4 As shown, the separator 4 includes a separator 41 and a suction section 42. The suction section 42 is provided with a plurality of suction holes, which communicate with the suction box 13. Specifically, the separator 41 corresponds to the position during bagging. During bagging, the suction cup needs to lift the top of the double-layer packaging bag 7. By setting the suction section 42, the bottom layer of the packaging bag 7 is completely sucked up, ensuring that the bag opening can be opened smoothly without obstruction.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
