Description

Technical Field

[0001] The present invention relates to the technical field of folding small pieces of fabric after cutting, and particularly relates to a folding and bagging machine and a bagging method. Background Art

[0002] For products made of small pieces of fabric such as glasses cloth, towels, and handkerchiefs, after production, they generally need to be folded and bagged for subsequent packaging and transportation.

[0003] Currently, in the prior art, a Chinese patent discloses a conveying and folding mechanism for fabric folding, with the publication number CN107055190B, which can adjust the reciprocating movement range of two moving rollers, thereby folding fabrics of different widths. Its folding effect is good and the efficiency is high. Moreover, the distance between the two moving rollers can be finely adjusted to allow fabrics of different thicknesses to pass between the two moving rollers. However, using moving rollers to convey unfolded fabrics is relatively complex for small pieces of fabric.

[0004] In addition, in another prior art, a Chinese patent also discloses a fabric folding machine, with the publication number: CN110143481A. Through the setting of the first folding device and the second folding device, secondary folding of the fabric is achieved, reducing the floor space occupied by the folded fabric. Moreover, both the first folding device and the second folding device adopt the method of pressing down the fabric and then folding it. For small pieces of fabric, pressing down and folding significantly makes the structure more complex.

[0005] In addition, after the above two types of folding, it is difficult to dock with external bagging equipment, and other conveying mechanisms need to be designed, resulting in problems such as a complex overall structure and large occupied space.

[0006] Therefore, we propose a folding and bagging machine to simply realize the folding and bagging processes, reduce the complexity of the structure, and meet the folding and bagging of small pieces of fabric. Summary of the Invention

[0016] As a preferred technical solution of the present invention, the material guiding plate includes a semi-helical section docked with the two first folding plates, and an inclined section integrally provided with the semi-helical section.

[0017] As a preferred technical solution of the present invention, the second folding member includes a second connecting rod installed inside the box body, two third folding plates symmetrically installed on the upper part of the second connecting rod and capable of relative movement, and a second cylinder installed inside the box body.

A guide plate 5 for flattening and turning over the horizontally folded cloth is connected to the discharge end of the first folding member 4. A second folding member 6 for vertically folding the horizontally folded cloth is docked at the discharge end of the guide plate 5. A squeezing roller 7 for squeezing and pulling the folded cloth is docked at the discharge end of the second folding member 6. An outlet 8 for discharging the folded cloth is opened at the side of the box body 2 adjacent to the squeezing roller 7. There are two squeezing rollers 7, and a passage 71 for the folded cloth to pass through is formed between the two squeezing rollers 7; a first electric suction cup 9 for opening and closing the packaging bag is installed on the side of the carrier table 1 adjacent to the outlet 8. The folded cloth discharged from the outlet 8 directly enters the opened packaging bag. There are two first electric suction cups 9, and the bag opening of the packaging bag faces the position of the outlet 8.

[0046] As Figure 1 、 Figure 2 and Figure 3 shown, the carrier table 1 includes a table body 11 and a support frame 12 installed on the upper part of the table body 11. The box body 2 is installed on the upper part of the table body 11. The table body 11 itself includes a table board and support feet. The support frame 12 is assembled from profiles.

[0047] As Figure 1 、 Figure 2 and Figure 3 shown, in order to facilitate the supply of small pieces of cloth, a support plate 13 for supporting the cloth to be folded is installed on the upper part of the table body 11. The support plate 13 is adjacent to the feed end of the conveyor belt 3. A second electric suction cup 14 for transferring the cloth to be folded onto the upper part of the conveyor belt 3 is installed on the upper part of the table body 11. The second electric suction cup 14 is installed at the lower part of the support frame 12 through an electric sliding table 15, and the lower part of the second electric suction cup 14 faces the upper part of the support plate 13. During specific use, small pieces of cloth are placed layer by layer on the upper part of the support plate 13. The uppermost small piece of cloth is adsorbed by the operation of the second electric suction cup 14, and then the second electric suction cup 14 is driven to move by the operation of the electric sliding table 15, so that the small piece of cloth is transferred to the upper part of the conveyor belt 3 to achieve a good feeding process.

[0048] like Figure 4 and Figure 5 As shown, the first folding member 4 includes a first connecting rod 41 installed inside the box body 2, two first folding plates 42 symmetrically installed on the upper part of the first connecting rod 41 and relatively movable, and a first cylinder 43 installed inside the box body 2.

In specific operation, the tilted first folding plate 42 can make the cloth move along the first folding plate 42 under the action of its own gravity when entering the upper part of the first folding plate 42, and the first cylinder 43 drives the second folding plate 44 to move downward, pressing down the middle part of the cloth supported on the upper part of the two first folding plates 42, and at the same time, the spacing between the two first folding plates 42 is adjusted to be smaller, so as to realize the transverse folding of the cloth, and a single action can form creases at the first folding plate 42 and the second folding plate 44.

[0049] like Figure 4 and Figure 5 As shown, in this embodiment, a slide groove 45 is provided on the upper part of the first connecting rod 41, and the two first folding plates 42 are slidably installed on the inner side of the slide groove 45 through sliders 46 respectively, and the two sliders 46 are connected by a double-threaded rod 47. A driving motor 48 is installed on the side of the first connecting rod 41, and the output end of the driving motor 48 is connected to the double-threaded rod 47. When in use, the double-threaded rod 47 is driven to rotate by the operation of the driving motor 48, so that the two sliders 46 are simultaneously approached or separated under the action of the threads, thereby driving the two first folding plates 42 to simultaneously approach or separate, and when approaching, the cloth is folded; when separated, it is in a reset state, waiting for the next cloth to be folded.

[0050] like Figure 4 As shown, in this embodiment, the guide plate 5 includes a semi-spiral segment 51 connected to the two first folding plates 42, and an inclined segment 52 integrally provided with the semi-spiral segment 51, so that the fabric that has been folded laterally can slide along the first folding plates 42 into the inner side of the semi-spiral segment 51, so that the vertical fabric gradually enters the inclined segment 52, thereby reaching a state similar to being paved.

[0051] like Figure 4As shown in the figure, the second folding member 6 includes a second connecting rod 61 installed inside the box body 2, two third folding plates 62 symmetrically installed on the upper part of the second connecting rod 61 and capable of relative movement, and a second air cylinder 63 installed inside the box body 2. The output end of the second air cylinder 63 is installed with a fourth folding plate 64. The fourth folding plate 64 faces the part between the two third folding plates 62. The two third folding plates 62 are docked with the inclined section 52. Similar to the working process of the first folding member 4, no further description will be given here.

[0052] In addition, the present invention also provides a bagging method for a folding bagging machine, including the following steps:

[0053] S1. Feeding: The cloth to be folded is laid flat on the conveyor belt 3, and the conveyor belt 3 transports the cloth to the first folding member 4.

[0054] S2. Horizontal folding: After the cloth is separated from the conveyor belt 3, under the action of gravity, it falls into the first folding member 4 and is horizontally folded.

[0055] S3. Turning: The horizontally folded cloth falls onto the guiding plate 5 under the action of gravity. Under the action of its own gravity, it moves along the guiding plate 5 and changes from a vertical state to a flat state.

[0056] S4. Vertical folding: The cloth exported from the guiding plate 5 falls into the second folding member 6 under the action of gravity and is vertically folded.

[0057] S5. Bagging: Under the extrusion action of the extrusion roller 7, the folded cloth is discharged from the discharge port 8 and enters the externally opened packaging bag. After entering the packaging bag, the first electric suction cup 9 closes the packaging bag, and the bagging is completed.

[0058] In summary: Through the transmission method of the conveyor belt 3, the present invention can conveniently transport the small pieces of cut cloth. Compared with directly using the moving roller to transport the cloth, it has better adaptability to small cloths; by using the form of height difference, under the action of the self-weight of the cloth, the feeding in the folding process is completed, with a simple structure and convenient operation; and after folding, bagging can be carried out to complete the overall packaging process.

[0059] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications.
