Description

Technical Field

[0001] This application relates to the field of linen folding machine technology, specifically a vertical single-blade folding device. Background Technology

[0002] A linen folding machine is a device used to fold blankets and other linens. It completes the folding and sorting of linens by folding a single layer of linen multiple times in the length and width directions. Linen folding machines are mainly suitable for laundry facilities in hotels, hospitals, and large laundry plants. They are used to fold bed sheets, tablecloths, duvet covers, pillowcases, towels, and other linens after washing and ironing by selecting the appropriate program. Each fold of the linen is carried out independently by the folding machine. Generally, the folded linens are sent to the discharge table by a conveyor belt. The staff stands in front of the discharge table. After each linen comes out, the staff needs to remove the linen so that the next linen can be discharged smoothly.

[0003] However, current linen folding machines generally use a long-blade direct-drive structure when folding linens with folding blades to ensure the folding quality or the folding width that the linens can cover. If such a structure is required to ensure the folding effect, more space is needed. Generally, the interior of a linen folding machine cannot accommodate such a large size. If a large-sized blade is used, it will compress the space for horizontal folding of the linens, affecting the folding quality of the linens. Utility Model Content

[0004] The purpose of this invention is to provide a vertical folding device to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this application to solve its technical problem is:

[0006] A vertical folding device includes a frame and a cutting tool. The cutting tool is vertically and movably mounted on the frame. A linkage structure connects the frame and the cutting tool. The linkage structure includes a first traction rod, a second traction rod, a first push rod, and a second push rod. Both the first and second push rods are L-shaped. One end of the first traction rod is mounted on the frame, and the other end of the first traction rod is hinged to one end of the first push rod. Both the first and second push rods are hinged to the frame, and the other ends of the first and second push rods are hinged to the cutting tool. One end of the first traction rod is hinged to one end of the second push rod, and the other end of the first traction rod is hinged to the first push rod.

[0007] Preferably, the linkage structure further includes a cylinder, one end of which is rotatably connected to the frame, and the output end of the cylinder is fixedly connected to one end of the first traction rod.

[0008] Preferably, the first push rod is divided into a first right end, a first corner portion and a first left end. The first right end is hinged to the cutter, the first corner portion is hinged to the frame, the first left end is hinged to one end of the first traction rod, and one end of the second traction rod is located between the first corner portion and the first left end.

[0009] Preferably, the second push rod includes a second right end, a second corner portion, and a second left end. The second right end is hinged to the cutter, the second corner portion is hinged to the frame, and the second left end is hinged to one end of the second traction rod.

[0010] Preferably, the first traction rod and the second traction rod are distributed in parallel.

[0011] The beneficial effects of this application are:

[0012] This invention incorporates a linkage structure between the cutter and the frame. This linkage structure significantly reduces the space required for folding during the vertical movement of the cutter, thereby reducing the overall space occupied by the cutter device. This allows the folding machine to accommodate larger linens, and the length of the cutter is not affected by the linkage structure. The longer the cutter, the larger the linens that can be folded, further accommodating larger linens.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0024] Please see Figure 1-4 The embodiments provided by this utility model are as follows:

[0025] The vertical folding device includes a frame 1 and a cutter 2. The cutter 2 is vertically and movably mounted on the frame 1. A connecting rod structure 3 connects the frame 1 and the cutter 2. The connecting rod structure 3 includes a first traction rod 32, a second traction rod 33, a first push rod 34, and a second push rod 35. Both the first push rod 34 and the second push rod 35 are L-shaped structures. One end of the first traction rod 32 is set on the frame 1, and the other end of the first traction rod 32 is hinged to one end of the first push rod 34. Both the first push rod 34 and the second push rod 35 are hinged on the frame 1. The other ends of the first push rod 34 and the second push rod 35 are hinged to the cutter 2. One end of the first traction rod 32 is hinged to one end of the second push rod 35, and the other end of the first traction rod 32 is hinged to the first push rod 34. The first traction rod 32 and the second traction rod 33 are distributed in parallel.

[0026] Please see Figures 1 to 3 In this embodiment, when the linen is folded by the cutter 2, one end of the first traction rod 32 moves. At this time, the other end of the first traction rod 32 pushes one end of the first push rod 34 to move synchronously. The first push rod 34 rotates on the frame 1. Under the action of the second traction rod 33, the first push rod 34 drives the second push rod 35 to rotate synchronously. Due to the L-shaped structure of the first push rod 34 and the second push rod 35, as... Figure 3As shown, when the first push rod 34 and the second push rod 35 rotate counterclockwise, one end of the first push rod 34 and the second push rod 35 will drive the cutter 2 to move downward. The first push rod 34 and the second push rod 35 are divided into a long end and a short end. The short end is used to drive the first push rod 34 and the second push rod 35 to rotate counterclockwise as a whole, while the long end is used to drive the cutter 2 to move downward, so as to realize the folding of the linen. Compared with the traditional direct-drive cutter 2, this application greatly reduces the space occupied by the cutter 2 when it moves vertically. It only needs to push the first traction rod 32 to move the cutter 2 downward.

[0027] It should be noted that the blade 2 will also make a slight horizontal movement during the vertical movement, but this horizontal movement does not affect the folding process of the linen.

[0028] The linkage structure 3 also includes a cylinder 31, one end of which is rotatably connected to the frame 1, and the output end of the cylinder 31 is fixedly connected to one end of the first traction rod 32.

[0029] Please see Figures 1 to 3 In this embodiment, after the cylinder 31 is started, the output end of the cylinder 31 can drive one end of the first traction rod 32 to move on the frame 1, so as to realize the overall downward movement of the tool 2. The cylinder 31 is used as a driving source in this embodiment, and the cylinder 31 is installed horizontally, which further reduces the space occupied by the whole compared with the direct drive structure of the traditional tool 2.

[0030] The first push rod 34 is divided into a first right end 341, a first corner portion 342, and a first left end 343. The first right end 341 is hinged to the cutter 2, the first corner portion 342 is hinged to the frame 1, and the first left end 343 is hinged to one end of the first traction rod 32. One end of the second traction rod 33 is located between the first corner portion 342 and the first left end 343. The second push rod 35 includes a second right end 351, a second corner portion 352, and a second left end 353. The second right end 351 is hinged to the cutter 2, the second corner portion 352 is hinged to the frame 1, and the second left end 353 is hinged to one end of the second traction rod 33.

[0031] Please see Figure 3 and Figure 4Specifically, cylinder 31 drives the first traction rod 32 to move as a whole. At this time, the first traction rod 32 pushes the first right end 341 to move synchronously. Since the first corner part 342 is hinged to the frame 1, the first right end 341 can drive the first corner part 342 to rotate, so that the first right end 341 can revolve around the first corner part 342 as the center. The first right end 341 will be raised in height, and then the first traction rod 32 drives the cylinder 31 to rotate as a whole on the frame 1 to adapt to the height of the first right end 341. The degree of increase is achieved, and at the same time, the first corner portion 342 can drive the first left end portion 343 to revolve. The first left end portion 343 then drives the cutter 2 to move vertically, while the first right end portion 341 can also drive the second traction rod 33 to move. The second traction rod 33 then drives the second left end portion 353 to move. The second left end portion 353 then causes the second corner portion 352 to rotate on the frame 1. The second corner portion 352 drives the second right end portion 351 to revolve, so that the second right end portion 351 cooperates with the first right end portion 341 to drive the cutter 2 to move down synchronously.

[0032] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
