DETAILED DESCRIPTION

[0025] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application are clearly and completely described below. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts also fall within the scope of protection of this application.

[0026] refer to Figures 3 to 7 , the filter screen replacement device for the rubber filter head includes:

[0027] The rubber filter head 100 is arranged on the rubber filter and has a drawer opening 101 on one side thereof; wherein, the size of the drawer opening 101 can be set according to actual needs, therefore, this application does not make any specific limitation on it.

[0028] The fixed frame 200 houses a filter plate 201. A filter channel 300 is defined in the center of the filter plate 201 for filtering impurities from the rubber material entering the strainer. The filter channel 300 includes a plurality of filter holes 301. The shape of the filter channel 300 matches the feed port on the strainer head 100 (through which the rubber material within the strainer barrel enters the strainer head). The number of filter holes 301 and the diameter of each filter hole 301 can be set according to actual needs and are not specifically limited in this application.

[0029] The hydraulic cylinder 400 is arranged on the rubber filter machine near the rubber filter head 100 and its telescopic end is connected to one side of the fixed frame 200, and is used to drive the other side of the fixed frame 200 (the end of the fixed frame 200 away from the hydraulic cylinder 400) through the drawing opening 101 to extend into the rubber filter machine head 100 or pull the fixed frame 200 out of the rubber filter machine head 100.

[0030] The present application provides a filter screen replacement device for a rubber filter head, which is provided with a pull-out opening 101 on the rubber filter head 100, and a filter plate 201 with a filter channel 300 in the middle for filtering impurities in the rubber entering the rubber filter is arranged in a fixed frame 200, wherein the filter channel 300 includes a plurality of filter holes 301, a hydraulic cylinder 400 is provided on the rubber filter near its head and one side of the fixed frame 200 is provided on the telescopic end of the hydraulic cylinder 400, and the hydraulic cylinder 400 is used to move the filter plate 201 to the fixed frame 200. The end of the movable fixed frame 200 away from the hydraulic cylinder 400 extends into the drawing port 101 and filters impurities entering the filter channel 300 through the filter channel 300 formed by multiple filter holes 301 on the filter plate 201, or the fixed frame 200 is pulled out from the drawing port 101 to clean the filter channel 300 on the filter plate 201 and replace the filter plate 201. The replacement process of the above-mentioned filter plate 201 is simple to operate, saves time and effort, and improves the replacement efficiency of the filter plate 201.

[0031] In some embodiments, the pore size of each filter hole 301 in the present application is 3 mm to 10 mm. This pore size range is smaller than the particle size of impurities typically mixed into the rubber material. This ensures that the filter hole 301 can filter out impurities in the rubber material. The specific pore size of each filter hole 301 can be set based on actual conditions to ensure that the filter hole 301 can filter out impurities in the rubber material, thereby ensuring the purity of the rubber material. Therefore, this application does not specifically limit this.

[0032] In some embodiments, each filter hole 301 in the present application is a conical hole, and the filter hole 301 diffuses along the direction of the rubber flow in the rubber filter. That is, the rubber inlet of the filter hole 301 is smaller than the diameter of its rubber outlet, and the aperture of the filter hole 301 gradually increases along the flow direction of the rubber. This is to ensure that when the rubber enters from the rubber inlet of the filter hole 301, impurities in the rubber can be filtered out and stay outside the rubber inlet of the filter hole 301. The flow rate of the rubber after the impurities are filtered out gradually increases with the increase of the aperture of the filter hole 301, thereby improving the rubber filtering efficiency.

[0033] In some embodiments, reference Figure 6 In the present application, a slide groove 102 is provided in the rubber strainer head 100, and a slider 202 matching the slide groove 102 is provided on the fixed frame 200. The slider 202 can move horizontally along the length direction of the slide groove 102. In order to improve the stability of the slider 202 on the fixed frame 200 sliding in the slide groove 102, there can be two slide grooves 102, and the two slide grooves 102 are respectively provided at the inner top and inner bottom of the rubber strainer head 100, and each slide groove 102 corresponds to a slider 202, that is, the number of sliders 202 corresponds to the number of slide grooves 102.

[0034] In the above embodiment, the fixed frame 200 is arranged in the slide groove 102 in the rubber filter head 100 through the slider 202 thereon. During the contraction process of the hydraulic cylinder 400, the telescopic end of the hydraulic cylinder 400 drives the slider 202 on the fixed frame 200 to slide out of the slide groove 102 in the rubber filter head 100, that is, the fixed frame 200 comes out of the rubber filter head 100 and then the filter plate 201 on the fixed frame 200 is cleaned or replaced. After the cleaning or replacement process of the filter plate 201 is completed, the telescopic end of the hydraulic cylinder 400 is extended to make the slider 202 on the fixed frame 200 slide along the slide groove 102 into the rubber filter head 100.

[0035] In some embodiments, reference Figure 7 In the present application, a fixing groove 203 is defined on the inner circumference of the fixing frame 200. A compression spring 500 is disposed in one side of the fixing groove 203. A connecting post 2011 is disposed on one side of the filter plate 201 to match the compression spring 500. The end of the connecting post 2011, which is away from the filter plate 201, extends into the compression spring 500 (that is, one end of the compression spring 500 is fixed in the fixing groove 203, while the other end is connected to the filter plate 201). The circumference of the filter plate 201 is embedded in the fixing groove 203. When a certain pressure is applied to the compression spring 500 by one side of the filter plate 201, the compression of the compression spring 500 generates a resistance force, making the filter plate 201 more stable in the fixing groove 203.

[0036] In some embodiments, reference Figure 3 The telescopic end of the hydraulic cylinder 400 in the present application is penetrated by a connecting rod 401 perpendicular thereto, and the connecting rod 401 is provided with at least two fixing clamps 4011 for fixing and clamping one side of the fixed frame 200. That is to say, there are at least two connection points between the hydraulic cylinder 400 and the fixed frame 200. The number of points of force exerted by the hydraulic cylinder 400 on the fixed frame 200 through the connecting rod 401 is increased, making the process of the hydraulic cylinder 400 driving the fixed frame 200 to extend into the rubber filter machine head 100 or to be pulled out from the rubber filter machine head 100 more stable.

[0037] In some embodiments, reference Figure 7 The length of the fixed frame 200 in the present application is greater than the width of the rubber filter head 100, so that it is convenient to push the fixed frame 200 connected to its telescopic end into the rubber filter head 100 or pull it out from the rubber filter head 100 through the hydraulic cylinder 400, making the cleaning and replacement of the fixed frame 200 more convenient.

[0038] In addition, a sealing ring 204 is provided on the fixed frame 200 and matches the inner circumference of the withdrawal opening 101. In this way, when the fixed frame 200 enters the rubber filter machine head 100 through the withdrawal opening 101, the fixed frame 200 is sealed and connected to the withdrawal opening 101, avoiding air leakage in the rubber filter machine head 100, thereby ensuring the sealing performance in the rubber filter machine head 100 and increasing the flow rate of the rubber material.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
