Description

Technical Field

[0001] The utility model belongs to the technical field of casing processing, and in particular relates to a filter screen installation device in casing production. Background Art

[0002] The statements in this section merely provide background technical information related to the present invention and do not necessarily constitute prior art.

[0003] In the production process of collagen casings, impurities in the collagen raw materials need to be filtered out before extrusion molding. Extrusion filtration is a common filtering method in the production process of collagen casings. In the prior art, the filtering device used in casing production usually consists of a filter screen with sealing rings at both ends and a corresponding filter cartridge. When assembling this filtering device, the filter screen needs to be loaded into the corresponding filter cartridge, but due to the presence of the sealing ring, the filter screen and the filter cartridge need external force to complete the sealed assembly. Therefore, the staff often use a tool hammer to continuously hammer the pot cover of the filter screen to smash the filter screen into the filter cartridge. This method not only easily damages the filter screen, but also wastes the physical strength of the staff. Utility Model Content

[0004] In view of the above problems, the utility model provides a filter installation device for casing production, which is a special tool for installing a filter with sealing rings at both ends into a filter cartridge. The filter is fixed at the opening of the filter cartridge using a fixing card. After the filter is placed in the filter cartridge, the push rod of the pressure rod is made to support one end of the filter. The filter can be squeezed into the filter cartridge by pressing down the pressure rod. The installation process is simple and convenient and will not damage the filter.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

DETAILED DESCRIPTION

[0024] It should be noted that the following detailed descriptions are all exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0025] The following drawings are combined to explain the utility model in detail. The present embodiment discloses a filter installation device for casing production, such as Figure 1 As shown, it includes a pressure rod 1, which is rotatably connected to a fixing member 2, and a push rod 3 is fixedly arranged on the pressure rod 1; the fixing member 2 is fixed on the open ring 41 of the filter cartridge 4, and the filter screen 5 is initially placed in the filter cartridge 4, and the top of the push rod 3 supports the pot cover part 51 of the filter screen 5, and the pressure rod 1 is pressed downward so that the push rod 3 pushes the filter screen 5 to be completely pressed into the filter cartridge.

[0026] like Figure 2 As shown, the fixing member 2 includes an upper fixing plate 21 and a lower fixing plate 22. The upper fixing plate 21 and the lower fixing plate 22 are both rectangular plates with a semicircular opening on one side. The upper fixing plate 21 and the lower fixing plate 22 have the same size and shape. The upper fixing plate 21 and the lower fixing plate 22 are butted together to form a square plate with a circular hole in the middle. The radius of the circular hole matches the radius of the opening ring 41 of the filter cartridge 4, so that the upper fixing plate 21 and the lower fixing plate 22 after butt-jointing can just accommodate the opening ring 41 of the filter cartridge 4.

[0027] like Figure 3 Therefore, an open ring 41 is provided at the open end of the filter cartridge 4, and the radius of the open ring 41 coincides with the radius of the circular hole formed by the upper fixing plate 21 and the lower fixing plate 22 after docking and fixation. The radius of the open ring 41 is smaller than the radius of the outer wall of the filter cartridge, so that the open ring 41 is accommodated in the circular hole in the middle of the fixing member 2, while the fixing member 2 is also supported by the protrusions of the filter cartridge before and after the open ring 41 and cannot move.

[0028] The fixing part 2 can accommodate the open ring 41 of the filter cartridge 4 by docking with the upper fixing plate 21 and the lower fixing plate 22. The fixing part 2 is fixedly installed on the open ring 41, so that the pressure rod 1 rotates downward around the fixing part 2, and at the same time drives the push rod 3 to rotate downward. At this time, the push rod 3 pushes the filter screen 5 into the filter cartridge 4, so that the filter screen 5 can be pressed into the filter cartridge 4.

[0029] The difference between the upper fixing plate 21 and the lower fixing plate 22 is that a pressure rod groove 23 is fixedly provided on the top of the upper fixing plate 21, and a first bolt hole is provided at the pressure rod groove 23 and the end of the pressure rod 1, and the end of the pressure rod 1 is rotatably connected to the pressure rod groove 23 through a first bolt 24, and the width of the pressure rod groove 23 is slightly larger than the diameter of the pressure rod 1. These arrangements enable the pressure rod groove 23 to just accommodate the end of the pressure rod 1, and the pressure rod 1 can rotate around the first bolt 24 in the pressure rod groove 23, so that the pressure rod 1 can achieve a rotatable connection with the fixing member 2.

[0030] The lower left corner of the upper fixing plate 21 and the upper left corner of the lower fixing plate 22 of the fixing member 2 are both provided with ear plates 25 of the same size, and the two ear plates 25 are correspondingly provided with second bolt holes. The ear plates 25 of the upper fixing plate 21 and the lower fixing plate 22 are overlapped together and rotatably connected by the second bolt 26, so that the upper fixing plate 21 and the lower fixing plate 22 can rotate around the second bolt 26. The upper fixing plate 21 and the lower fixing plate 22 of the fixing member 2 rotate relative to each other. In the non-working state, the other ends of the upper fixing plate 21 and the lower fixing plate 22 can be separated, and the fixing member 2 is in an open state as a whole. When working, the other ends of the upper fixing plate 21 and the lower fixing plate 22 can be butted, and the fixing member 2 is in a closed state as a whole.

[0031] like Figure 2 As shown, the lower right corner of the upper fixing plate 21 and the upper right corner of the lower fixing plate 22 are fixedly provided with a protrusion 27 of the same size, and the protrusion 27 is correspondingly provided with a third bolt hole, and the upper fixing plate 21 and the lower fixing plate 22 are closedly connected by the third bolt 28. This makes the fixing member 2 in the working state, the upper fixing plate 21 and the lower fixing plate 22 are docked, the open ring 41 is accommodated in the fixing member 2, and the upper fixing plate 21 and the lower fixing plate 22 are connected by the third bolt 28, and the fixing member 2 completes the fixing of the open ring 41 of the filter cartridge 4.

[0032] like Figure 4 As shown, the front and rear ends of the filter screen 5 are provided with a front sealing ring 52 and a rear sealing ring 53, and one end of the filter screen 5 is provided with a pot cover portion 51, and the radius of the pot cover portion 51 is larger than the radius of the opening end of the filter cartridge 4. These arrangements are all for the purpose of sealing the pot cover portion 51 after the filter screen 5 is inserted into the filter cartridge 4 through the opening end of the filter cartridge 4; but it is precisely the existence of the sealing ring that makes it impossible to achieve a sealed installation when the filter screen 5 is inserted into the filter cartridge 4 without the aid of external force.

[0033] like Figure 1As shown, the push rod is in an L-shaped shape, the angle between the long end and the pressure rod 1 is an acute angle, and the angle between the short end and the long end of the push rod is greater than 90°. When the filter screen 5 is installed into the filter cartridge 4, the front end sealing ring 52 of the filter cartridge cannot be installed into the filter cartridge 4 without the action of external force. At this time, the short end of the push rod is supported against the pot cover 51, and the short end of the push rod is horizontal. When the pressure rod 1 rotates downward, the push rod 3 will also rotate and move forward part of the stroke in the direction of the filter cartridge 4, squeezing the filter screen into the filter cartridge.

[0034] A method for using a filter screen installation device in casing production:

[0035] Put the filter screen 5 into the filter cartridge 4 first, until the filter screen 5 can no longer enter the filter cartridge 4 under the action of the sealing ring, place the upper fixing plate 21 and the lower fixing plate 22 of the fixing member 2 at the open ring 41, and make the upper and lower fixing plates rotate and dock around the second bolt. At this time, the raised parts 27 of the upper and lower fixing plates are docked together, and the fixing member 2 is fixed to the open ring 41 with the third bolt 28, and the pressure rod 1 is rotated so that the short end of the push rod 3 supports the pot cover part 51 of the filter screen 5, and then the pressure rod 1 is rotated downward to drive the push rod 3 to press the filter screen 5 forward, thereby pressing the filter screen 5 into the filter cartridge 4.

[0036] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
