Description

Technical Field

[0001] The utility model relates to the technical field of filter screen processing, in particular to a folding and winding forming device for raw materials used in processing filter screens. Background Art

[0002] In the field of filtration technology, filter paper and filter screens, as key components, are widely used in multiple industries such as water treatment, air purification, and food processing. Filter paper, with its good adsorption and air permeability, serves as the basic material for manufacturing filter screens. The filter screen, through specific forming processes such as folding and winding, enhances its filtration area and efficiency to meet the requirements of different application scenarios. The folding and winding forming device is a special device designed for this demand. It can precisely process the original filter paper material into an efficient filter screen with a complex folding structure.

[0003] Currently in the market, the folding and winding forming devices for raw materials used in processing filter screens generally adopt the following working principles and processes: First, the device receives a roll of continuous filter paper as the raw material, and presses evenly distributed creases on the surface of the filter paper through a preset creasing mechanism. These creases provide a positioning reference for the subsequent folding operation of the filter paper. Subsequently, the filter paper is fed into the folding mechanism and folded according to a preset folding pattern (such as Z-shaped, W-shaped, etc.) to finally form a multi-layer staggered filter screen structure. Throughout the process, the filter paper needs to maintain continuous movement during the creasing and folding steps to ensure production efficiency.

[0004] However, the existing folding and winding forming devices have several significant drawbacks during the processing. First, since the filter paper is usually creased only on one side during the creasing stage, while the subsequent folding operations are alternating, this results in that during the folding process, some of the pre-pressed creases do not directly serve the current folding direction but instead become obstacles, increasing the complexity and instability of folding. Second, although the continuous movement of the filter paper during the creasing process ensures the production speed, it may also cause unnecessary pulling on the filter paper due to improper speed control or defects in the mechanical structure design, thereby affecting the flatness of the filter screen and the final filtration effect. In addition, long-term pulling may damage the fiber structure of the filter paper and reduce its service life. Therefore, developing a folding and winding forming device that can optimize the crease layout, reduce the pulling of the filter paper, and improve the forming accuracy and efficiency of the filter screen has become an urgent problem in the industry.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary, and should not be construed as limiting the scope of protection of the present utility model.

[0025] It should be noted that like reference numerals denote like elements in the following drawings. Therefore, once an element is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0026] This embodiment mainly elaborates on the structure of the creasing device, which is specifically as follows:

[0027] A folding and winding forming device for processing raw materials for filters, as Figure 1 and Figure 2 shown, includes a support base 1, a filter paper folding machine 101, a filter paper feeding roller 102, a baffle 103, and a collection box 104. The support base 1 is composed of multiple bottom plates and support blocks. A filter paper folding machine 101 is installed in the middle of the support base 1. This machine is used to fold the filter paper in half so that it is reciprocally folded when passing through. A baffle 103 is connected to the rear of the filter paper folding machine 101. A collection box 104 is connected to the rear of the support base 1. The interior of the collection box 104 is designed with an inclined surface. The interior of the collection box 104 is designed as an inclined surface to ensure that the filters can be stacked horizontally when entering, avoiding tilting. Two filter paper feeding rollers 102 are rotatably connected to the front side of the support base 1. It also includes a creasing assembly 2 and a trimming assembly. The creasing assembly 2 is arranged on the support base 1, located between the filter paper folding machine 101 and the filter paper feeding roller 102. The creasing assembly 2 is used to press creases on the passing filter paper. A trimming assembly is arranged behind the filter paper folding machine 101 for trimming the folded filter paper.

[0028] As Figures 2-4As shown in the figure, the crease component 2 includes a mold base 201, a reciprocating crease pressing block 202, a motor 203, a full gear I 204, a full gear II 205, a missing gear 206, a full gear III 207, a gear set 209, and a connecting rod 208. The mold base 201 is fixedly connected to the support base 1. The reciprocating crease pressing block 202 is slidably connected to the mold base 201. A motor 203 is installed at the front end of the support base 1. A full gear I 204 is connected to the output shaft of the motor 203. The full gear II 205 is rotatably connected to the support base 1. A missing gear 206 is connected to the outside of the full gear II 205. The full gear III 207 is fixedly connected to the left end of the central axis of the upper filter paper feeding roller 102. The full gear I 204 meshes with the full gear II 205. The missing gear 206 meshes with the full gear III 207. A gear set 209 is connected to the right end of the filter paper feeding roller 102. A connecting rod 208 is slidably connected to the missing gear 206. The other end of the connecting rod 208 is fixedly connected to the reciprocating crease pressing block 202. The motor 203 controls the moving speed of the reciprocating crease pressing block 202 through multiple gears. The moving speed of the reciprocating crease pressing block 202 through the filter paper is equal to the feeding and winding speed of the filter paper feeding roller 102. And the motor 203 needs to cooperate with the filter paper folding machine 101 to make the feeding and winding speed of the filter paper feeding roller 102 slightly greater than the speed of the filter paper folding machine 101 for folding the filter paper, so as to ensure that when folding the filter paper, the filter paper folding machine 101 will not pull the front-end filter paper, resulting in the situation of the filter paper being torn.

[0029] As Figure 1 , Figure 2 and Figure 5 shown in the figure, the trimming component includes a knob 3, a lead screw 4, a bracket 5, and a cutting machine 6. A lead screw 4 is rotatably connected to the rear end of the baffle 103. A knob 3 is provided at one end of the lead screw 4 for rotating the lead screw 4. The thread directions at both ends of the lead screw 4 are opposite. And brackets 5 are threadedly connected to both ends of the lead screw 4. A cutting machine 6 is installed at the bottom of the bracket 5 for edge trimming of the filter paper.

[0030] The staff passes the filter paper through the filter paper feeding roller 102, the reciprocating crease pressing block 202, and the filter paper folding machine 101 in sequence, turns on the motor 203, the filter paper folding machine 101, and the cutting machine 6. Through multiple gear transmissions, the filter paper feeding roller 102 pushes the filter paper to move backward, then presses out a crease through the crease component 2, and then the filter paper folding machine 101 folds the filter paper back and forth to form the basic shape of the filter net. According to the production requirements, the edge of the folded filter paper is trimmed. When the filter paper touches the front end of the baffle 103, it will be squeezed and stacked together. Under the pulling of the leveling component, the filter paper will be unfolded again, pass through the bottom of the baffle 103, and after being trimmed by the leveling component, enter the collection box 104. The bottom of the collection box 104 is connected to other containers or the next processing equipment, and finally the production of the filter net is completed. When the folding work is completed, turn off the motor 203, the filter paper folding machine 101, and the cutting machine 6;

[0031] Regarding the working steps of the crease component 2, it should be supplemented that: Refer to Figure 3 and Figure 4 , after the motor 203 is turned on, the motor 203 drives the full gear I 204 to rotate. The full gear I 204 drives the full gear II 205 and the missing gear 206 to rotate. When the missing gear 206 meshes with the full gear III 207, the missing gear 206 drives the full gear III 207 to rotate, and through the cooperation between the gear sets 209, the two filter paper feeding rollers 102 rotate in opposite directions. The upper filter paper feeding roller 102 rotates counterclockwise, and the lower filter paper feeding roller 102 rotates clockwise, thereby pushing the filter paper between the two filter paper feeding rollers 102 backward. And the reciprocating crease pressing block 202 can only slide up and down, so the connected connecting rod 208 can also only slide up and down. The missing gear 206 makes the reciprocating crease pressing block 202 perform up and down reciprocating motion through the connecting rod 208, squeezing the passing filter paper, leaving evenly spaced indentations on both the upper and lower surfaces of the filter paper. Refer to Figure 4 , by designing the number of missing teeth at the top and bottom of the missing gear 206, the horizontal distance between the two pressing blocks of the reciprocating crease pressing block 202 can be balanced. At this time, when squeezing the filter paper from below, the indentation is far from the filter paper feeding roller 102, so the number of missing teeth at the upper end of the missing gear 206 is less, making the distance for pushing out the filter paper longer. When alternating to the upper indentation, the number of missing teeth of the missing gear 206 is more, shortening the pushing out distance, so that the spacing between the indentations is equal;

[0032] According to the width of the filter screen required for production, turn the knob 3, thereby rotating the lead screw 4, adjusting the position of the bracket 5 on the lead screw 4, and adjusting the distance between the two cutting machines 6. When the filter paper passes through the two cutting machines 6, the edge contacts the opened cutting machine 6, and the cutting machine 6 trims the filter paper into the target width and pulls the filter paper backward.

[0033] As Figure 1 and Figure 5 shown, it further includes a pulverizer 7 and a guiding plate 8. The rear end of the bracket 5 is connected with the guiding plate 8, and a pulverizer 7 is installed on the support base 1. The feed inlet of the pulverizer 7 is located on the extension line of the rear end of the guiding plate 8.

[0034] The trimmed filter paper, through the guidance of the guiding plate 8, directly enters the pulverizer 7, is pulverized into fine paper scraps, and is stored in the pulverizer 7 for convenient reuse.

[0035] As Figure 1 and Figure 2 shown, it further includes a vacuum cleaner 9. The vacuum cleaner 9 is installed on the top of the filter paper folding machine 101, close to the filter paper transmission path, and is used to effectively absorb the dust on the surface of the filter paper.

[0036] When folding the filter paper, turn on the vacuum cleaner 9, and the vacuum cleaner 9 absorbs the dust on the surface of the filter paper from the top of the filter paper.

[0037] As Figure 1 and Figure 6 shown, it further includes a friction plate 10. The friction plate 10 is laid on the support base 1 and is located at the bottom of the baffle 103, and is used to slow down the movement of the folded filter paper, so as to be able to pull the filter paper according to the cutting efficiency of the cutting machine 6, ensuring that the filter paper passing through the cutting machine 6 is in a relatively flat state and is not squeezed by the subsequent filter paper.

[0038] As Figure 1 and Figure 2 shown, it further includes a buffer strip 11. The buffer strip 11 is connected to the filter paper feeding roller 102, and the buffer strip 11 is softly connected to the filter paper feeding roller 102 to ensure that the filter paper is stable and not easily damaged during the transmission process.

[0039] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present utility model is usually placed during use. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0040] The above has introduced in detail a folding and winding forming device for raw materials for processing filter meshes provided by the present utility model. Specific examples are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the present utility model and the core idea. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
