[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Combination Figure 1-4 As shown, a high-efficiency double-channel linen folding machine comprises a frame, a first folding mechanism 100 and a second folding mechanism 200 are sequentially arranged along the linen conveying direction, the second folding mechanism 200 folds the linen and conveys it to a horizontally arranged second conveyor belt 201, two first folding mechanisms 100 are arranged side by side, corresponding to the two second folding mechanisms 200 arranged side by side, the two second folding mechanisms 200 correspond to the left third folding mechanism 310 and the right third folding mechanism 330 respectively, above the second conveyor belt 201, a left third folding mechanism 310, a center third folding mechanism 320, and a right third folding mechanism 330 are sequentially arranged along a direction perpendicular to the conveying direction, and a left fourth folding mechanism 410, a center fourth folding mechanism 420, and a right fourth folding mechanism 430 are respectively arranged below the left third folding mechanism 310, the center third folding mechanism 320, and the right third folding mechanism 330, and the center fourth folding mechanism 420 folds the linen and conveys it to the right fourth folding mechanism 430 for folding. The first folding mechanism 100 and the second folding mechanism 200 fold the linens along the first direction, the left third folding mechanism 310, the center third folding mechanism 320, the right third folding mechanism 330, the left fourth folding mechanism 410, the center fourth folding mechanism 420, and the right fourth folding mechanism 430 fold the linens along the second direction, and the first direction is perpendicular to the second direction.

[0025] In this technical solution, since two first folding mechanisms and two second folding mechanisms are arranged side by side, they correspond to the third folding mechanism on the left and the third folding mechanism on the right, respectively, and further correspond to the fourth folding mechanism on the left and the fourth folding mechanism on the right, which is equivalent to having two sets of folding mechanisms that can perform four folds, greatly improving efficiency; in addition, when it is necessary to fold the linen five times, since the two first folding mechanisms are arranged side by side, the two second folding mechanisms are arranged side by side, and the central third folding mechanism and the central fourth folding mechanism are arranged, the folding directions of the first folding mechanism and the second folding mechanism arranged side by side are the same, so at this time, after folding, the linen enters the central third folding mechanism, folds in the central third folding mechanism along another direction, and then enters the central fourth folding mechanism, and after completing such four folds, it is transported to the fourth folding mechanism on the right for the fifth folding, which is used for the folding of large linens. This technical solution can double-channel linens that only need four folds, greatly improving folding efficiency; at the same time, it can also single-channel linens that need five folds, and is highly applicable.

[0026] Furthermore, each first folding mechanism 100 includes a feed conveyor belt 101 and a first folding assembly arranged at the output end of the feed conveyor belt 101. A first conveyor belt 102 is arranged below the feed conveyor belt 101. The feed conveyor belt 101 conveys linens toward the top surface. After the feed conveyor belt 101 rotates, the bottom surface and the first conveyor belt 102 are mutually attached to form a first folding interval 103. A first folding gap 104 is formed between the output end of the feed conveyor belt 101 and the input end of the first conveyor belt 102. The first folding assembly folds the linens in half at the first folding gap 104 and enters the first folding interval 103. The first folding assembly includes a plurality of first jet holes 105 evenly distributed along the first folding gap 104, and the plurality of first jet holes 105 are aligned with the first folding gap 104. A first baffle 106 is arranged below the input end of the first conveyor belt 102. The linens are attached to the surface of the first baffle 106 after being output from the feed conveyor belt 101.

[0027] In this technical solution, this is the first folding of the linen. The two first folding mechanisms are arranged side by side, and can fold the large linen separately or simultaneously. When the middle of the linen reaches the first folding gap, the air jet is ejected from the air jet hole, and the linen enters the first folding interval for folding. The function of the first baffle is to prevent the linen from interfering with other components. Placing the first baffle can ensure that the linen is flat.

[0028] Further, the second folding mechanism 200 includes a second folding assembly arranged at the output end of the first conveyor belt 102, the second conveyor belt 201 is arranged below the first conveyor belt 102, a second folding gap 202 is formed between the output end of the first conveyor belt 102 and the input end of the second conveyor belt 201, the turning roller at the output end of the first conveyor belt 102 and the turning roller at the output end of the second conveyor belt 201 are arranged relative to each other to form a second folding interval 203, and the second folding assembly folds the linen at the second folding gap 202 and enters the second folding interval 203. The second folding assembly includes a plurality of second jet holes 204 evenly distributed along the second folding gap 202, the plurality of second jet holes 204 are aligned with the second folding gap 202, and a third jet hole 205 is respectively arranged below each second jet hole 204, and the third jet hole 205 is aligned with the bottom of the second folding gap 202.

[0029] In this technical solution, this is the second folding of the linen. The two second folding mechanisms are arranged side by side, and large linens can be folded separately or simultaneously. When the middle of the linen reaches the second folding gap, the air jets are ejected from the air jet holes, and the linen enters the second folding interval for folding. Since the linen has a certain thickness after the first folding, a third air jet hole is added at the bottom to flatten the linen below the folding position to ensure the best folding effect.

[0030] Furthermore, the left third folding mechanism 310, the center third folding mechanism 320, and the right third folding mechanism 330 respectively include vertical folding components arranged in sequence perpendicular to the conveying direction of the second conveyor belt 201, each vertical folding component includes a vertical folding plate 301 and a first driving cylinder 302 for driving the vertical folding plate 301 to move vertically, the second conveyor belt 201 forms a third folding gap 303 under each vertical folding plate 301, and two mutually bonded third conveyor belts 304 are respectively arranged under each vertical folding plate 301 along the conveying direction of the second conveyor belt 201, and a third folding section 305 is formed between the two mutually bonded third conveyor belts 304, and each vertical folding plate 301 folds the linen in half at the third folding gap 303 and enters the third folding section 305.

[0031] In this technical solution, by moving the vertical folding plate vertically downward, since the vertical folding plate is arranged along the conveying direction of the second conveyor belt and is in the middle position, the linens are folded down directly from the middle, and the folding effect is optimal. Due to the vertical folding method, the second conveyor belt passes through multiple guide belts arranged side by side, thus forming a third folding gap. Of course, the other conveyor belts are all conveyed in the form of multiple guide belts arranged side by side, and there are gaps along the conveying direction, and related parts will not interfere. The third folding interval is formed by clamping between the two third conveyor belts. After the linens are folded, they can be shaped in the third folding interval and conveyed to the next stage.

[0032] Furthermore, the fourth folding mechanism 410 on the left includes a fourth conveyor belt 411, which receives the linen output from the output end of the third conveyor belt 304 on the left, and also includes a fifth conveyor belt 412 capable of forward and reverse conveying, a first transition plate 413, a second driving cylinder 414 for driving the first transition plate 413 to rotate, a first folding plate 415, and a third driving cylinder 416 for driving the first folding plate 415 to rotate. A fourth folding gap 417 is formed between the turning roller of the fifth conveyor belt 412 close to the direction in which the linens come from and the fourth conveyor belt 411, and a fourth folding interval 418 is formed between the fourth conveyor belt 411 and the fifth conveyor belt 412. When the linen moves from the first transition plate 413 to the fifth conveyor belt 412 and is located in the middle of the fourth folding gap 417, the fifth conveyor belt 412 conveys in the reverse direction, and the first folding plate 415 folds the linen and enters the fourth folding interval 418.

[0033] Furthermore, the fourth folding mechanism 430 on the right side includes a sixth conveyor belt 431, which receives the linen output from the output end of the third conveyor belt 304 on the right side, and also includes a seventh conveyor belt 432 that can convey in forward and reverse directions, a second transition plate 433, a fourth driving cylinder 434 that drives the second transition plate 433 to rotate, a second folding plate 435, and a fifth driving cylinder 436 that drives the second folding plate 435 to rotate. A fifth folding gap 437 is formed between the turning roller of the seventh conveyor belt 432 close to the direction in which the linens come and the sixth conveyor belt 431, and a fifth folding interval 438 is formed between the sixth conveyor belt 431 and the seventh conveyor belt 432. When the linens move to the middle of the seventh conveyor belt 432 via the second transition plate 433 and are located in the fifth folding gap 437, the seventh conveyor belt 432 conveys in the reverse direction, and the second folding plate 435 folds the linens and enters the fifth folding interval 438.

[0034] In this technical solution, the fourth folding mechanism on the left is similar to the fourth folding mechanism on the right. Both first transition to the upper rotatable conveyor belt through a transition plate. When the middle of the linen reaches the folding gap, the transition plate returns to prevent interference. At the same time, the folding plate folds the linen into the folding interval and completes the folding output.

[0035] Furthermore, the central fourth folding mechanism 420 includes an eighth conveyor belt 421, a third folding plate 422, and a sixth driving cylinder 423 for driving the third folding plate 422 to rotate, and the sixth conveyor belt 431 simultaneously receives the linen output from the output end of the central third conveyor belt 304, and a sixth folding gap 424 is formed between the turning roller of the eighth conveyor belt 421 close to the direction of the linen and the central third conveyor belt 304, and a sixth folding interval 425 is formed between the eighth conveyor belt 421 and the central third conveyor belt 304. When the middle of the linen reaches the sixth folding gap 424, the third folding plate 422 folds the linen and enters the sixth folding interval 425. After passing through the sixth folding interval 425, the linen is output via the eighth conveyor belt 421 to the sixth conveyor belt 431 and transported to the fourth folding mechanism 430 on the right side.

[0036] In this technical solution, when large linens need to be folded and need to be folded five times, the central third folding mechanism and the central fourth folding mechanism are used to perform the third and fourth folds. During the fourth fold, the linens are stuffed into the sixth folding interval through the folding plate and then the linens that have been folded four times are conveyed to the fourth folding mechanism on the right side through the sixth conveyor belt for the fifth folding, which is achieved by simultaneously connecting the central fourth folding mechanism and the right fourth folding mechanism through the sixth conveyor belt.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0038] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
