Description

Technical Field

[0001] The utility model relates to the technical field of membrane coating devices, in particular to a folded filter element membrane coating device. Background Art

[0002] A pleated filter element is a fixed-pore depth filter element using ultrafine polypropylene fiber as the filter medium. It has the advantages of high retention rate, high flow rate, low pressure difference and wide chemical compatibility. The production process adopts a unique hot-melt welding process technology, without any adhesives and no foreign matter release, thus meeting the production requirements of the food, beverage, beer, chemical, pharmaceutical and other industries. After the pleated filter element is processed, it is usually wrapped with a packaging film. The packaging film is then heated to shrink and wrap the pleated filter element tightly, fully displaying the appearance of the pleated filter element, improving the display and sales of the pleated filter element, increasing its aesthetics, and preventing dust. The existing pleated filter element coating device (Announcement No.: CN116080971B) has the following disadvantages in use:

[0003] During use, the folded filter element body can automatically wrap the packaging film around it to complete the packaging process, without the need for manual packaging by staff, which effectively improves work efficiency. After the packaging is completed, the cutting knife will automatically cut the packaging film. However, during the cutting process, the packaging film is straightened and will bounce off after being cut. The next time it is packaged, it is necessary to manually find the end of the film and wrap it again, which is inconvenient. For this reason, this patent proposes a folded filter element packaging device to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] After the pleated filter element 5 is processed, it is usually wrapped with a packaging film 4 on the outside, and then the packaging film 4 is heated to shrink and wrap the pleated filter element 5 tightly, fully displaying the appearance of the pleated filter element 5, improving the exhibition and sales properties of the pleated filter element 5, increasing its aesthetics, and dust prevention. The utility model provides a pleated filter element coating device that clamps the packaging film 4 by setting a limiting cutting mechanism 8 and a second limiting mechanism 9. In this way, after the cutting of the packaging film 4 is completed, the cut end will not fall elsewhere, making it convenient for subsequent staff to wrap the packaging film 4 around the surface of the next group of pleated filter elements 5.

[0022] like Figure 1-Figure 5As shown, the utility model provides a technical solution: a folded filter element membrane device, comprising a base plate 1, a first fixed plate 2 and a second fixed plate 3 are fixed to the top of the base plate 1, one side of the first fixed plate 2 is rotatably connected to the first rotating plate 13 and the second rotating plate, two motors are fixed to the other side of the first fixed plate 2, the output ends of the two motors pass through the first fixed plate 2 and are fixed to the first rotating plate 13 and the second rotating plate respectively, a first connecting rod 10 and a second connecting rod 11 are respectively installed on one side of the first rotating plate 13 and the second rotating plate, the outer walls of the first connecting rod 10 and the second connecting rod 11 are respectively inserted with the packaging film 4 and the folded filter element 5, one side of the first fixed plate 2 is rotatably connected to the first rotating rod 6 and the second rotating rod 7, and a limited cutting mechanism 8 and a second limiting mechanism 9 are provided on one side of the first fixed plate 2. The limiting cutting mechanism 8 includes a connecting plate 801 fixed to the top of the base plate 1. A telescopic rod 802 is fixed to the end of the connecting plate 801 near the second connecting rod 11. A mounting plate 803 is fixed to the telescopic end of the telescopic rod 802. A first fixed housing 804 is fixed to one end of the mounting plate 803. A first clamping plate 805 is slidably connected within the first fixed housing 804. A first spring 806 is fixed between the first clamping plate 805 and the inner wall of the first fixed housing 804. A cutting blade 807 is fixed to one end of the mounting plate 803. The second limiting mechanism 9 includes a second fixed housing fixed to one side of the first fixed plate 2. A second clamping plate is slidably connected within the second fixed housing.

The cutting blade 807 is movably inserted into the protective housing 12.

[0023] It should be noted that, by rotating the first connecting rod 10 and the second connecting rod 11, the packaging film 4 and the folded filter element 5 are driven to rotate, so that the packaging film 4 wraps the folded filter element 5. When the wrapping is completed, the mounting plate 803 is driven to move to the right by the telescopic rod 802, so that the first clamping plate 805 moves to clamp the packaging, and then the telescopic rod 802 continues to move to the right, the first clamping plate 805 compresses the first spring 806, and the cutting knife 807 cuts the packaging. After the cutting is completed, the two ends of the packaging are clamped respectively. Between the first clamping plate 805 and the surface of the folded filter element 5 and the second clamping plate and the second rotating rod 7, the telescopic rod 802 then drives the cutting knife 807 to move a little to the left, and the second connecting rod 11 continues to rotate. The first clamping plate 805 presses the membrane so that the end of the membrane completely covers the surface of the folded filter element 5. Then the telescopic rod 802 drives the first clamping plate 805 to move to the left, so that the cutting knife 807 moves into the protective shell 12, and then the packaged folded filter element 5 is removed for the next group of packaging.

[0024] like Figure 3 and Figure 5As shown, the first support frame and the second support frame are fixed to the side of the second fixing plate 3 away from the first fixing plate 2, and the first cylinder and the second cylinder are fixed to one side of the first support frame and the second support frame respectively. The output ends of the first cylinder and the second cylinder pass through the second fixing plate 3 and are rotatably connected to the first limit plate 15 and the second limit plate respectively. The first limit plate 15 is located on one side of the first connecting rod 10, and the second limit plate is located on one side of the second connecting rod 11.

A first threaded rod 14 is fixed to one side of the first rotating plate 13 and the second rotating plate, and the first threaded rod 14 is screwed into the mounting groove.

[0025] It should be noted that by setting the first cylinder and the second cylinder, the first cylinder drives the first limit plate 15 to move, so that the insertion rod 16 on one side of the first limit plate 15 moves out, which is convenient for removing the packaging film 4, and the second cylinder drives the second limit plate to move, so that the insertion rod 16 on one side of the second limit plate moves out, which is convenient for removing the folded filter element 5. The first connecting rod 10 and the second connecting rod 11 can be removed from the first threaded rod 14, which is convenient for replacing different models of first connecting rods 10 and second connecting rods 11, and convenient for plugging in packaging films 4 and folded filter elements 5 of different sizes.

[0026] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the accompanying embodiments and their equivalents.
