Description

Technical Field

[0001] The utility model relates to the field of fitted sheet packaging, in particular to a feeding device of a fitted sheet packaging machine. Background Art

[0002] Before the fitted sheet enters the fitted sheet packaging machine, workers first need to fold it into a long, flat structure because the entire sheet is a square structure, and then send it to the packaging machine. However, when folded by workers, the folded sheet is likely to be uneven, and the widths of multiple fitted sheets will also be different. This will result in different folded shapes after being sent to the fitted sheet packaging machine, which will give customers an unpleasant impression. They will feel that the returned fitted sheet has been refolded and sent out again. In addition, workers will be too tired from long-term folding, and the folding speed is relatively slow and not fast enough. Therefore, it is necessary to design a feeding device for a fitted sheet packaging machine that can fold a square fitted sheet into a long, flat structure, without the need for workers to fold it, but using equipment for folding. Utility Model Content

[0003] The purpose of the utility model is to provide a feeding device for a fitted sheet packaging machine.

[0004] To achieve this purpose, the present invention adopts the following technical solutions:

[0005] Provided is a feeding device for a fitted sheet packaging machine, comprising a laying and conveying mechanism, a folding mechanism 1, and a folding mechanism 2 arranged in sequence. The laying and conveying mechanism is used to horizontally convey the fitted sheet laid on its upper surface by a worker into the folding mechanism 1. The folding mechanism 1 and the folding mechanism 2 have the same structure and are symmetrically arranged. The folding mechanism 1 is used to fold the right side of the fitted sheet toward the left, and the folding mechanism 2 is used to fold the left side of the fitted sheet toward the right. The folding mechanism 1 comprises a belt conveyor 1, a turning mechanism, and a mounting frame 1. The belt conveyor 1 and the turning mechanism are both fixedly mounted on the mounting frame 1. The belt conveyor 1 is used to horizontally convey the fitted sheet placed on its upper surface. The turning mechanism is used to rotate and fold the fitted sheet used for the area directly above it from right to left.

[0006] Furthermore, the laying and conveying mechanism includes a second belt conveyor and a second mounting frame. The second belt conveyor is fixedly mounted on the second mounting frame. The second belt conveyor is used to support and convey the fitted sheet laid on its upper surface.

[0020] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0021] Among them, the drawings are only used for illustrative purposes and represent only schematic diagrams rather than actual pictures, and should not be understood as limitations on this patent; in order to better illustrate the embodiments of the utility model, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product.

[0022] Reference Figures 1 to 6 The illustrated feeding device for a fitted sheet packaging machine includes a laying conveyor mechanism 1, a folding mechanism 2, and a folding mechanism 3 arranged in sequence. The laying conveyor mechanism 1 is used to horizontally convey the fitted sheet placed on its upper surface by a worker into the folding mechanism 2. The folding mechanism 2 and the folding mechanism 3 have the same structure and are symmetrically arranged. The folding mechanism 2 is used to fold the right side of the fitted sheet to the left, while the folding mechanism 2 is used to fold the left side of the fitted sheet to the right. This results in the originally square fitted sheet being flipped and folded twice, resulting in a flat, elongated structure. The folding mechanism 2 includes a belt conveyor 2a, a flipping mechanism 2b, and a mounting frame 2d. Both the belt conveyor 2a and the flipping mechanism 2b are fixedly mounted on the mounting frame 2d. The belt conveyor 2a is used to horizontally convey the fitted sheet placed on its upper surface, while the flipping mechanism 2b is used to rotate and fold the fitted sheet from right to left, which is placed directly above it. First, a worker lays the fitted sheet on the top surface of laying conveyor mechanism 1. Laying conveyor mechanism 1 then conveys it horizontally to the top surface of belt conveyor 1a of folding mechanism 2. Belt conveyor 1a then transports the right third of the fitted sheet to the top of flipping mechanism 2b, where flipping mechanism 2b rotates this third of the fitted sheet, completing the first fold. The worker then proceeds to folding mechanism 2 3 in the same manner, where the flipping mechanism on folding mechanism 3 folds the left third of the fitted sheet. After two folds, the fitted sheet becomes a flat, long structure. Folding mechanism 2 3 is docked to the right of fitted sheet packaging machine 4, where the folded, flat, long sheet is transported to this packaging machine for packaging.

[0023] The laying and conveying mechanism 1 comprises a belt conveyor 1a and a mounting frame 1c. Belt conveyor 1a is fixedly mounted on mounting frame 1c and supports and conveys the fitted sheet placed on its upper surface. Two workers unfold the fitted sheet on either side of mounting frame 1c and place it on belt conveyor 1a. Belt conveyor 1a then transports the fitted sheet to folding mechanism 2.

[0024] Belt Conveyor 1a has the same structure as Belt Conveyor 2a. Belt Conveyor 2a includes a rotary driver 1a2, two rotating shafts 1a4, and multiple pulleys 1a3 mounted on each rotating shaft 1a4. The two rotating shafts 1a4 are rotatably mounted on a mounting frame 1c. The two pulleys 1a3 mounted on the two rotating shafts 1a4 are connected to each other through a transmission mechanism. Rotary driver 1a2 is fixedly mounted on mounting frame 1c, and the output end of rotary driver 1a2 is fixedly connected to one of the rotating shafts 1a4. When rotary driver 1a2 is activated, it rotates one of the rotating shafts 1a4. The connection between pulleys 1a3 and the endless belt 1a1 causes multiple endless belts 1a1 to rotate simultaneously, effectively conveying the belts placed on the upper surfaces of the endless belts 1a1. Belt Conveyor 2a also uses the same structure to transport fitted sheets.

[0025] The flipping mechanism 2b comprises a rotary driver 2b2, a rotating shaft 2b3, and multiple curved plates 2b1. One end of each of the belt curved plates 2b1 is fixedly mounted on the rotating shaft 2b3. Each curved plate 2b1 is positioned between two endless belts of the belt conveyor 1 2a. The rotating shaft 2b3 is rotatably mounted on the mounting frame 1 2d. The output end of the rotary driver 2b2 is fixedly connected to the rotating shaft 2b3. By controlling the rotary driver 2b2 to operate, the rotary driver 2b2 rotates the multiple curved plates 2b1 via the rotating shaft 2b3, causing the multiple curved plates 2b1 to rotate and flip the fitted sheet. The multiple curved plates 2b1 are embedded between the endless belts and do not obstruct the conveying of the fitted sheet before flipping.

[0026] Mounting frame 2 (1c) is secured with support plate 1b, which is inserted into the middle of the endless belt (1a1), with its top contacting the inner edge of the belt (1a1). Supporting support plate 1b prevents the belt (1a1) from bending due to the weight of the fitted sheet.

[0027] A second support plate 2c is fixed to mounting frame 1 2d. Support plate 2c is inserted into the middle of the endless belt of folding mechanism 1 2, with the top of support plate 1b contacting the top inner edge of the endless belt of folding mechanism 1 2. The support provided by support plate 2c prevents the endless belt of folding mechanism 1 2 from bending due to the weight of the fitted sheet.

[0028] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
