Description

Technical Field

[0001] This utility model relates to the field of filter element processing technology, and in particular to a pleating machine for the filter cloth of a water purifier filter element. Background Technology

[0002] A water purifier is a water treatment device that performs deep filtration and purification of water according to the requirements of water use. Carbon rod filter cartridges are a commonly used type of filter cartridge in water purifiers. They are mainly made of activated carbon through a special process. The filter cloth is wrapped around the outside of the carbon rod filter cartridge or is part of the filter cartridge. It can protect the core filter material inside the filter cartridge from contamination and damage by external impurities. By pleating the filter cloth of the water purifier filter cartridge at an angle, the effective area of ​​the filter cloth can be greatly increased within the limited space of the filter cartridge.

[0003] Existing technology, patent number CN220597975U, discloses a polyester fabric heat-setting and pleating machine. When the polyester fabric passes through the pleating groove, an electric push rod drives the pleating plate to perform pleating and heat treatment, creating pleats on its surface to enhance its decorative effect or meet specific needs. Simultaneously, the polyester fabric is conveyed through a first and second rotating roller, which provide stable support and tension, ensuring the polyester fabric remains flat during processing and maintaining consistency across the fabric except for the pleated areas, avoiding unnecessary wrinkles or deformation. In practical use, existing technology involves pressing the filter cloth into the pleating groove by the pleated plate at the bottom of the horizontal plate. The filter cloth is then heated by the electric heating plate inside the pleating plate, causing it to pleat. However, it is inconvenient to pleat the bottom of the filter cloth. If the bottom of the filter cloth is not pleated, the water flow is prone to short-circuiting at the bottom, causing a large number of impurities to pass through without being fully filtered, which seriously reduces the filter element's ability to purify water. Filter elements without bottom pleats have weak bottom pressure resistance, so further improvements are needed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a pleating machine for the filter cloth of a water purifier filter element.

[0005] This utility model is achieved through the following technical solution:

[0006] A filter cloth pleating machine for a water purifier filter element includes a mounting frame and a pleating assembly. The pleating assembly includes a stepper motor, a forward and reverse lead screw, multiple sliders, a slide rod, and two hollow pleating plates. The stepper motor is fixedly mounted on the top of the mounting frame, and the output shaft end of the stepper motor is fixedly connected to the forward and reverse lead screw. The forward and reverse lead screw is movably connected to the mounting frame via bearings. The top and bottom ends of the slide rod are fixedly connected to the mounting frame. The four sliders are movably sleeved on the forward and reverse lead screw and the slide rod, and one side of each slider is fixedly connected to the two hollow pleating plates. A heating assembly is provided between the two hollow pleating plates. The heating assembly includes a heat storage box, multiple heat-resistant hoses, multiple insulation pipes, a heater, and a three-way pipe.

[0007] Optionally, in one possible implementation, the two heat storage boxes are respectively fixedly installed at the top and bottom of the mounting frame, the two ends of the plurality of heat-resistant hoses are respectively fixedly connected to the two heat storage boxes and the two hollow pleated plates, and the two ends of the four heat insulation pipes are respectively fixedly connected to the two heat storage boxes.

[0008] Optionally, in one possible implementation, the heater is fixedly installed on one side of the mounting bracket, and the output end of the heater is fixedly connected to a three-way pipe, with the front and rear ends of the three-way pipe respectively fixedly connected to two of the insulation pipes.

[0009] Optionally, in one possible implementation, a base is fixedly connected to the bottom end of the mounting bracket, wherein the base serves to facilitate support of the mounting bracket.

[0010] Optionally, in one possible implementation, a side frame is fixedly connected to one side of the mounting bracket, and a guide assembly is provided on the side frame. The guide assembly includes a guide roller, a lead screw, and two extrusion sleeves.

[0011] Optionally, in one possible implementation, both ends of the guide roller are in contact with the side frame, one end of the lead screw passes through the guide roller, and both extrusion sleeves are threadedly connected to the lead screw. It can be seen that the above technical solution facilitates the guiding of different filter cloths.

[0012] Optionally, in one possible implementation, the side frame is provided with multiple insertion holes. It can be seen that in the above technical solution, this is to facilitate the insertion of the lead screw.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] This invention uses a stepper motor to drive forward and reverse lead screws, which in turn move two hollow pleating plates in opposite directions. The two hollow pleating plates pleat the top and bottom of the filter cloth. The heat generated by the heater enters two heat storage boxes through a three-way pipe and two insulation pipes, and finally enters the two hollow pleating plates through multiple heat-resistant hoses to heat the two hollow pleating plates. It is simple to operate, convenient for pleating the top and bottom of the filter cloth, and has good performance.

[0015] Meanwhile, by placing the guide roller inside the side frame and then passing one end of the lead screw through the side frame and the guide roller, the guide roller is connected to the side frame. The two extrusion sleeves are rotated in sequence and brought into contact with the front and rear sides of the side frame, thereby limiting the lead screw. Similarly, other guide rollers are installed on the side frame as needed. The filter cloth passes through multiple guide rollers and enters the interior of the mounting frame. Different filter cloths can be guided by multiple guide rollers. The structure is simple and easy to use. Attached Figure Description

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and preferred embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] Example 1: As Figure 1-4 As shown, a filter cloth pleating machine for a water purifier filter element includes a mounting frame 1 and a pleating assembly 2. The pleating assembly 2 includes a stepper motor 201, a forward and reverse lead screw 202, multiple sliders 203, a slide rod 204, and two hollow pleating plates 205. The stepper motor 201 is fixedly mounted on the top of the mounting frame 1, and the output shaft end of the stepper motor 201 is fixedly connected to the forward and reverse lead screw 202. The forward and reverse lead screw 202 is movably connected to the mounting frame 1 through bearings. The top and bottom ends of the slide rod 204 are fixedly connected to the mounting frame 1. The four sliders 203 are movably sleeved on the forward and reverse lead screw 202 and the slide rod 204, and one side of each of the four sliders 203 is fixedly connected to the two hollow pleating plates 205. A heating assembly 3 is arranged between the two hollow pleating plates 205. The heating assembly 3 includes a heat storage box 301, multiple heat-resistant hoses 302, multiple heat-insulating pipes 303, a heater 304, and a three-way pipe 305.

[0025] Furthermore, two heat storage boxes 301 are fixedly installed at the top and bottom of the mounting frame 1, respectively. The two ends of multiple heat-resistant hoses 302 are fixedly connected to the two heat storage boxes 301 and the two hollow pleated plates 205, respectively. The two ends of four insulation pipes 303 are fixedly connected to the two heat storage boxes 301, respectively. The heater 304 is fixedly installed on one side of the mounting frame 1, and the output end of the heater 304 is fixedly connected to the three-way pipe 305. The front and rear ends of the three-way pipe 305 are fixedly connected to two of the insulation pipes 303, respectively.

[0026] Furthermore, a base 4 is fixedly connected to the bottom end of the mounting bracket 1, wherein the base 4 serves to facilitate support for the mounting bracket 1.

[0027] In use, the stepper motor 201 is started, driving the forward and reverse lead screw 202 to rotate. Since two sliders 203 are threadedly connected to the forward and reverse lead screw 202, and the other two sliders 203 and the sliding rod 204 cooperate to restrict the rotation of the two hollow pleated plates 205, the forward and reverse lead screw 202 can drive the two hollow pleated plates 205 to move towards each other. Simultaneously, because the multiple heat-resistant hoses 302 are relatively long, the two hollow pleated plates 205 can cause the multiple heat-resistant hoses 302 to extend, through the two hollow pleats... Plate 205 pleats the top and bottom of the filter cloth. Similarly, the stepper motor 201 reverses to drive the two hollow pleated plates 205 to move in opposite directions. At the same time, the heater 304 is activated. The heat generated by the heater 304 enters the two heat storage boxes 301 through the three-way pipe 305 and the two heat insulation pipes 304. Finally, it enters the two hollow pleated plates 205 through multiple heat-resistant hoses 302 to heat the two hollow pleated plates 205. The operation is simple and convenient for pleating the top and bottom of the filter cloth, and the effect is good.

[0028] Example 2: As Figure 1 , 2 As shown in Figure 5, a filter cloth pleating machine for a water purifier filter element has a side frame 5 fixedly connected to one side of the mounting frame 1. A guide assembly 6 is provided on the side frame 5. The guide assembly 6 includes a guide roller 601, a lead screw 602 and two extrusion sleeves 603. Both the front and rear ends of the guide roller 601 are in contact with the side frame 5. One end of the lead screw 602 passes through the guide roller 601, and both extrusion sleeves 603 are threadedly connected to the lead screw 602. Multiple insertion holes are provided on the side frame 5.

[0029] In use, the guide roller 601 is placed inside the side frame 5, and then one end of the lead screw 602 is passed through the side frame 5 and the guide roller 601, thereby connecting the guide roller 601 to the side frame 5. The two extrusion sleeves 603 are rotated in sequence and brought into contact with the front and rear sides of the side frame 5, thereby limiting the lead screw 602. Similarly, other guide rollers 601 are installed on the side frame 5 as needed. The filter cloth passes through multiple guide rollers 601 and enters the interior of the mounting frame 1. Different filter cloths can be guided by multiple guide rollers 601. The structure is simple and easy to use.

[0030] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
