DETAILED DESCRIPTION

[0032] The specific embodiments according to the present disclosure will be described in detail below in conjunction with the various drawings.

[0033] As shown in the drawings, Figures 1-7 a medical single-fold folding mechanism includes a cloth conveying device 1, a cloth compression device 2, a first folding device 3, and a second folding device 4.

[0034] Among them, the cloth conveying device 1 includes a support 101, a conveying belt 102 rotatably mounted on the support 101, and a conveying power source (not shown due to visual obstruction) mounted on the support 101 and used to drive the conveying belt 102 to rotate. In this embodiment, the conveying power source uses a motor as the power source.

[0035] As for the cloth compression device 2, it is arranged above the middle part of the conveying belt 102, and it can be used to press the cloth on the conveying belt 102 downward.

[0036] In addition, the first folding device 3 and the second folding device 4 are respectively arranged on the left and right sides of the conveying belt 102, so as to perform folding operation on the cloth on the conveying belt 102.

[0037] Specifically, the first folding device 3 includes a first up-down driving assembly, a first front-rear driving assembly movably mounted on the output end of the first up-down driving assembly, two first left-right driving assemblies movably mounted on the output end of the first front-rear driving assembly respectively, and two first folding rods 31 movably mounted on the output end of the two first left-right driving assemblies respectively; the two first folding rods 31 can approach or separate from each other in the front-rear direction, so as to realize the folding of the cloth by using the two first folding rods 31.

[0038] Specifically, the second folding device 4 comprises a second up-down driving assembly, a second front-rear driving assembly movably installed on the output end of the second up-down driving assembly, two second left-right driving assemblies movably installed on the output end of the second front-rear driving assembly respectively, and two second folding rods 41 movably installed on the output end of the two second left-right driving assemblies respectively; the two second folding rods 41 can move towards or away from each other in the front-rear direction, so that the two second folding rods 41 can be used to fold the cloth.

[0039] Specifically in use, the first folding device 3 and the second folding device 4 can be used to fold the two ends of the cloth towards the middle part of the cloth in sequence several times by cooperation, so that the folded cloth can be easily unfolded when in use.

[0040] As shown in the drawings, Figures 1-4 In this embodiment, the cloth conveying device 1 further comprises two compression rollers 103; the two compression rollers 103 are located in front of and behind the pressing device 2 respectively; two left-right through insertion slots 104 are formed in the middle of the top surface of the conveying belt 102 by being recessed respectively, and the two compression rollers 103 are located in the two insertion slots 104 respectively and abut against the surface of the conveying belt 102; the two ends of the compression roller 103 are connected with the support 101 respectively; the two first folding rods 31 can be inserted into the two insertion slots 104 respectively when they are extended. Therefore, by arranging the two compression rollers 103, the surface of the conveying belt 102 can be ensured to form the two insertion slots 104 during the rotation of the conveying belt 102, so that the first folding rod 31 can be inserted into the insertion slot 104 in advance before the cloth is folded, and then the first folding rod 31 can be moved upwards to the bottom surface of the cloth and moved forward and backward in the subsequent folding process. Therefore, the reason for arranging the insertion slot 104 is to facilitate the movement of the first folding rod 31. If the insertion slot 104 is not arranged, the first folding rod 31 will be moved before the cloth is moved into position, which will easily block the normal movement path of the cloth, so that the cloth may be bent due to the obstruction of the folding rod; if the first folding rod 31 is inserted after the cloth is moved into position, the cloth will be relatively thin at this time, so that it will be difficult to accurately insert the first folding rod 31 under the cloth, and the cloth may be bent due to the direct insertion of the first folding rod 31, which is not conducive to the subsequent folding operation.

[0041] Preferably, the width of the insertion slot 104 should not be too large, so that the cloth cannot be bent and inserted into the insertion slot 104 when it is moved to the insertion slot 104, that is, the cloth cannot pass through the insertion slot 104 smoothly.

[0042] As shown in the drawings, Figures 1-7As shown, preferably, the first and second up-down driving assemblies each comprises a fixedly arranged up-down driving motor 5, an up-down screw 6 mounted on the output shaft of the up-down driving motor 5, and an up-down slider 7 movably mounted on the up-down screw 6; the first and second front-rear driving assemblies are respectively mounted on the up-down sliders 7 of the first and second up-down driving assemblies. Thus, through the above arrangement, the up-down slider 7 can be driven to move up and down by the rotation of the up-down screw 6 driven by the up-down driving motor 5, and the first and second front-rear driving assemblies can be simultaneously driven to move up and down by the movement of the up-down sliders 7 of the first and second up-down driving assemblies, thereby simultaneously driving the first and second left-right driving assemblies and the first and second folding rods 31 and 41 to move up and down.

[0043] As shown in Figures 1-7 As shown, preferably, the first and second front-rear driving assemblies each comprises a front-rear positioning seat 8, a front-rear driving motor 9 mounted on the front-rear positioning seat 8, a front-rear driving belt 10 rotatably mounted on the front-rear positioning seat 8 and driven by the front-rear driving motor 9, and two front-rear sliders 11 respectively mounted on the left and right sides of the front-rear driving belt 10; the front-rear driving motor 9 can drive the two front-rear sliders 11 to move closer to or away from each other in the front-rear direction when driving the front-rear driving belt 10 to rotate; the front-rear positioning seats 8 on the first and second front-rear driving assemblies are respectively connected to the output ends of the first and second up-down driving assemblies; the two front-rear sliders 11 on the first front-rear driving assembly are used to correspondingly connect the two first left-right driving assemblies; the two front-rear sliders 11 on the second front-rear driving assembly are used to correspondingly connect the two second left-right driving assemblies. Thus, through the above arrangement, each front-rear driving assembly can drive the corresponding two front-rear sliders 11 to move simultaneously when the corresponding front-rear driving belt 10 is driven to rotate by the single front-rear driving motor 9, specifically, the two front-rear sliders 11 can move closer to or away from each other, and each front-rear slider 11 can simultaneously drive the corresponding left-right driving assembly to move, i.e., the two first folding rods 31 and the two second folding rods 41 can move closer to or away from each other.

[0044] As shown in Figures 1-7 Specifically, as shown, the front-rear positioning seats 8 on the first and second front-rear driving assemblies are respectively connected to the two up-down sliders 7, so that the front-rear positioning seats 8 can be driven to move by the movement of the two up-down sliders 7, thereby driving the first and second front-rear driving assemblies.

Therefore, by arranging the cloth pressing block 22 driven by the cloth pressing cylinder 21, the cloth pressing block 22 can be used to press the middle part of the cloth on the conveying belt 102, thereby improving the stability of the cloth.

[0049] As shown in the drawings, Figures 1-4 Preferably, the cloth pressing block 22 extends left and right and the length of the cloth pressing block 22 is equal to the width of the conveying belt 102, so that the cloth pressing block 22 can stably press the cloth.

[0050] As shown in the drawings, Figures 1-3 The utility model also comprises a color mark sensor 20; the color mark sensor 20 is installed above the front end of the conveying belt 102. Specifically, the color mark sensor 20 can be used to detect whether the cloth is smoothly fed onto the conveying belt 102. When the cloth is detected to be fed onto the conveying belt 102, the left and right driving motors 15 in the two first left and right driving assemblies respectively drive the two first folding rods 31 to extend and correspondingly insert into the two insertion slots 104.

[0051] In the embodiment, the first folding rod 31 and the second folding rod 41 are both in the shape of a flat strip, so that they can be conveniently used to press and fold the cloth.
