Description

Technical Field

[0001] This invention relates to the field of cover folding, and more specifically to a cover folding device. Background Technology

[0002] Medical devices are diverse, and some, like laparoscopes, require long, cylindrical, disposable sterile protective covers. Ordinary folding packaging is cumbersome to open and use, difficult to slip on, and time-consuming. Medical personnel have proposed a folding method for these covers, allowing them to be easily pulled into place after alignment. This involves folding long, soft, cylindrical materials into a tubular shape with multiple layers of folded walls, allowing for axial pulling as needed. Currently, folding these cylindrical covers typically involves manual methods, such as using a mandrel to fold the material over and repeatedly roll it to create a multi-layered tube. This method is not only inefficient but also increases manual labor. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a cover folding device, which can automatically, orderly and efficiently realize the cover folding operation by means of the orderly expansion and contraction of the expansion rod and the reciprocating movement of the movable part, thereby greatly improving the folding efficiency.

Detailed Implementation

[0020] To better illustrate the content of this invention, the following description is provided in conjunction with the accompanying drawings and examples:

[0021] have Figures 1-3 As shown, the present invention discloses a cover folding device, including a machine base 1, a fixed part 2 fixed on the machine base 1, a movable part 15 provided on the side of the machine base 1 away from the fixed part 2, a moving mechanism 901 provided on the machine base 1 for driving the movable part 15 to move back and forth left and right, four sets of expansion rods 9 in a circular array are provided on the opposite side surfaces of the movable part 15 and the fixed part 2, and a cylinder mechanism 902 is provided inside the movable part 15 and the fixed part 2 for driving the expansion rods 9 to expand synchronously to the outside of the array center or to contract inward. The machine base 1 is also provided with a master controller 3 and a guide mechanism 903 for guiding the cover 11.

[0022] Furthermore, the cylinder mechanism 902 includes an air chamber 5 disposed inside the movable part 15 and the fixed part 2. The air chamber 5 is connected to the air station. Four annular array notches 6 are provided on opposite sides of the movable part 15 and the fixed part 2. The notches 6 of the movable part 15 and the notches 6 of the fixed part 2 are offset by 45 degrees. A piston part 8 is slidably disposed through the side wall of the notch 6 near the center of the array. The piston part 8 extends into the air chamber 5. A compression spring 7 is fixedly connected between the end of the piston part 8 near the center of the array and the inner wall of the air chamber 5.

[0023] Furthermore, the piston part 8 is fixedly connected to the expansion rod 9, and a roller 10 is provided at the end of the expansion rod 9 away from the piston part 8.

[0024] Furthermore, the guiding mechanism 903 includes a platform 13 fixed to the top of the movable part 15, and a limiting part 12 with symmetrical front and rear positions is fixed on the platform 13.

[0025] Furthermore, a first guide column surface 14 for guiding the cover 11 is fixed on the side of the movable part 15 near the fixed part 2. A fixed plate 19 is also provided on the movable part 15. Two support columns 16 are fixed on the fixed plate 19. A second guide column surface 21 for guiding the cover 11 is fixed at the upper end of the support column 16.

[0026] Furthermore, the moving mechanism 901 includes a slide groove 17 disposed in the upper surface of the machine base 1, a slider 18 slidably disposed in the slide groove 17, the movable part 15 fixedly placed on the slider 18, and an electric push rod 20 fixedly disposed between the slider 18 and the inner wall of the slide groove 17.

[0027] Furthermore, the master controller 3 is electrically connected to the electric push rod 20 and the gas station.

[0028] Furthermore, two proximity switches 4 are provided on both sides of the slide 17 to detect whether the moving part 15 has moved into place.

[0029] Specifically, in use, the cover 11 is placed between the limiting parts 12, one end of the cover 11 passes through the lower side of the second guide column surface 21 and is fitted on the outside of the four sets of expansion rods 9 of the fixing part 2 until the left end of the cover 11 is close to the piston part 8.

[0030] Then the main controller 3 controls the gas station to start, which increases the gas pressure in the gas chamber 5, pushes the piston part 8 to extend outward, compresses the compression spring 7, and thus expands the expansion rod 9 outward to support the cover 11.

[0031] Then the main controller 3 starts the electric push rod 20, which drives the movable part 15 to move to the left until the expansion rod 9 of the movable part 15 approaches the piston part 8 of the fixed part 2. At this time, the proximity switch 4 on the left detects that the movable part 15 has moved into place and gives the next action signal.

[0032] During this process, the roller 10 can reduce the friction between the cover 11 and the expansion rod 9;

[0033] This process folds the cover 11 and pulls the right end of the cover 11 to the left.

[0034] After the movable part 15 moves into place, the expansion rod 9 of the movable part 15 expands outward through the air station. At the same time, the expansion rod 9 of the fixed part 2 releases air through the air station and contracts inward under the elastic force of the compression spring 7. At this time, the cover 11 is supported by the movable part 15, and then the cover returns to the right side with the movable part 15.

[0035] The movable part 15 moves to the far right and is close to the right proximity switch 4. At this time, the right proximity switch 4 detects that the movable part 15 has moved into position and sends a signal for the next action.

[0036] Then the movable part 15 moves to the left again, moving the cover 11 to the leftmost side, and placing the cover 11 on the outside of the expansion rod 9 of the fixed part 2. After it is in place, the expansion rod 9 of the fixed part 2 expands outward to support the cover 11. At the same time, the expansion rod 9 of the movable part 15 retracts inward and moves to the right, pulling the expansion rod 9 out of the folding gap of the cover 11. At this time, the inner sleeve 11 is fixed on the expansion rod 9 of the fixed part 2, realizing one folding cycle operation.

[0037] Then the movable part 15 moves to the left again to fold the cover 11. At the same time, the right end of the cover 11 is pulled to the left to start the next round of folding until the cover 11 is completely folded, and then the folded cover 11 can be removed.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the technical solutions of the present invention have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
