Description

Technical Field

[0001] The utility model relates to the field of extrusion equipment, in particular to a movable screen changer. Background Technique

[0002] A screen changer is a manual or automatic switching device including one or more filter screens, which is used to filter out foreign particles and impurities when the plasticized material flows through the filter screen. The filter screen is supported by an alloy perforated plate, and the perforated plate is installed on a plate-type or column-type carrier, and the carrier can be moved to switch between the working position and the off-line non-working position of a system. The screen changer can be installed on any new or existing extruder, melt pump, reactor or other extrusion production line. It can be used to filter any type of polymer, rubber or ceramic melt.

[0003] The whole screen changer is made of alloy material and weighs more than a hundred catties. Once the screen changer is blocked or fails, and when the internal screw of the extruder needs to be replaced, the screen changer needs to be removed from the extruder, and then reinstalled after being repaired; because the screen changer is heavy, it is impossible to move it manually, so the cooperation of auxiliary equipment such as a crane is required, resulting in time-consuming and laborious disassembly and installation of the screen changer, which affects production. Summary of the Invention

[0004] In view of this, it is necessary to provide a movable screen changer that can realize the disassembly and installation of the screen changer from the extruder without other auxiliary lifting equipment.

[0005] In order to solve the above technical problems, the technical solution of the utility model is: a movable screen changer, including a screen changer body, further including:

[0006] A base, on the top of which a slide rail is provided;

[0007] A support column, the bottom of which is slidably connected to the slide rail, and the top of the support column is fixedly connected to the bottom of the screen changer body.

[0008] Further, the sliding direction of the support column is perpendicular to the feeding direction of the screen changer body.

[0009] Further, the number of the slide rails is two.

[0010] Further, a slider is fixedly connected to the bottom of the support column, and the slider is slidably connected to the slide rail.

[0011] Further, a locking bolt for restricting the movement of the slider is provided on the slider.

[0012] Further, a plurality of height adjusting rods for adjusting the height of the base are arranged on the periphery of the base. A cushion block is fixedly connected to the bottom of the height adjusting rod, and a nut for supporting the base is screwed to the lower part of the height adjusting rod.

[0013] Further, a support plate is fixedly connected to the top of the support column, and the bottom of the screen changer body is fixedly connected to the support plate.

[0014] Further, the support column is a square tube.

[0015] Further, limit posts are arranged at both ends of the slide rail, and the limit posts are fixedly connected to the base to prevent the slider from disengaging from the slide rail.

[0016] Further, a rubber pad facing the slider is fixedly connected to the limit post.

[0017] Compared with the prior art, the utility model has the following beneficial effects: A mobile carrier (i.e., the base, the slide rail and the support column) is arranged at the bottom of the screen changer. When the screen changer needs to be disassembled and installed, the heavy screen changer can be moved through the mobile carrier, without the need to rely on lifting equipment. The installation and disassembly are simple and fast, the use is convenient, and the working hours are saved.

[0018] In order to make the above and other objects, features and advantages of the utility model more obvious and understandable, the following specific preferred embodiments are given, and in conjunction with the accompanying drawings, the detailed description is as follows. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 It is a perspective view of an embodiment of the utility model.

[0020] In the figure: 1 - screen changer body, 2 - base, 21 - slide rail, 22 - limit post, 23 - rubber pad, 3 - support column, 31 - slider, 32 - support plate, 33 - locking bolt, 4 - height adjusting rod, 41 - cushion block, 42 - nut. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In order to further elaborate the technical means and effects adopted by the utility model to achieve the predetermined invention purpose, the following, in conjunction with the accompanying drawings and specific preferred embodiments, details the specific implementation manners, structures, features and their effects of the utility model as follows.

[0022] As Figure 1 shown, a movable screen changer includes a screen changer body 1, a base 2 and a support column 3; the screen changer body 1 is a conventional device in the extrusion field and has various types and models, and the technical solutions of this application are applicable to all of them.

[0023] There are two parallel slide rails 21 arranged on the top of the base 2. The direction of the slide rails 21 is perpendicular to the feeding direction of the screen changer body 1. The advantage of this design is that when the screw in the extruder needs to be replaced, the screen changer can completely avoid the extruder in this direction, leaving enough space for the installation and removal of the screw.

[0024] The bottom of the support column 3 is fixedly connected with a slider 31. The bottom of the slider 31 is slidably connected with the two slide rails 21. The top of the support column 3 is fixedly connected with a support plate 32. The bottom of the screen changer body 1 is fixedly connected with the support plate 32 through bolts.

[0025] In order to reduce the weight, the support column 3 is made of square tubes. In order to ensure the stability of the screen changer body 1, a locking bolt 33 for restricting the movement of the slider is arranged on the slider 31.

[0026] Four height adjusting rods 4 for adjusting the height of the base are arranged on the periphery of the base 2. The bottom of the height adjusting rod 4 is fixedly connected with a cushion block 41. The lower part of the height adjusting rod 4 is screwed with a nut 42 for supporting the base 2. By only adjusting the height of the nut 42, the height of the base 2 can be adjusted, and then the height of the screen changer body 1 can be adjusted.

[0027] Limit posts 22 are arranged at both ends of the slide rail 21. The limit posts 22 are fixedly connected to the base 2 to prevent the slider 31 from detaching from the slide rail 21. In order to avoid rigid collision, a rubber pad 23 facing the slider 31 is fixedly connected to the limit post 22.

[0028] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Although the present invention has been disclosed above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
