Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically a disc filter for eliminating crystal points in the protective film. Background Technology

[0002] Crystal points are one of the most common quality problems in the industrial production of PET protective films. Crystal points affect the appearance and adhesive coating quality of the protective film. To eliminate crystal points and impurities, current methods include changing the fineness of the filter screen during film production.

[0003] In the prior art, Chinese utility model publication CN204222136U discloses a disc filter for eliminating crystal points in the protective film. The melt enters the inner cavity of the cylinder through the first melt flow channel of the feed end cap. The melt is filtered through a circular disc filter screen, where impurity particles are blocked outside the screen. The filtered particles then enter the inner hole of the filter element through the filter holes. The filtered melt flows out through the inner hole and the second melt channel of the discharge end cap. This utility model uses a circular disc filter screen that effectively removes hard impurities and fine particles, while also possessing good durability and processability. The main filter material is a sintered stainless steel mesh with a filtration accuracy of 0.5–200 micrometers. It can be reused after multiple cleanings. The use of both the filter element and the circular disc filter screen effectively eliminates crystal points in the protective film.

[0004] The above technical solution improves the efficiency of eliminating crystal points, but the filter does not have a corresponding protective structure. As a result, the filter may be damaged by impact, which may affect the use of the protective membrane and reduce the efficiency of eliminating crystal points. Therefore, we need to propose a disc filter to eliminate crystal points on the protective membrane. Utility Model Content

[0005] The purpose of this invention is to provide a disc filter that eliminates crystal spots on the protective film. By adding a detachable protective structure to the filter housing, the protection effect of the filter is improved, the internal protective film is prevented from being damaged by impact, and the efficiency of the filter in eliminating crystal spots is improved, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a disc filter for eliminating protective film crystal points, comprising a filter body, two sets of support mechanisms are detachably installed on the outside of the filter body, multiple sets of adjustment mechanisms are arranged between the two sets of support mechanisms, the multiple sets of adjustment mechanisms are arranged at equal angles, and a protective mechanism is installed on the side of each set of adjustment mechanisms opposite to the filter body.

[0007] The protective mechanism includes a protective plate, a fixing block fixedly connected to the upper inner side of the protective plate, a first telescopic sleeve rod fixedly connected to both ends of one side of the fixing block, a first spring sleeved on the outer side of the two sets of first telescopic sleeve rods, a grooved guide plate fixedly connected to the lower inner side of the protective plate, a sliding plate slidably connected in the groove of the grooved guide plate, a second telescopic sleeve rod symmetrically fixedly connected to both ends of one side of the sliding plate, and a second spring sleeved on the outer side of the two sets of second telescopic sleeve rods.

[0008] Preferably, the two sets of first telescopic sleeve rods and the two sets of second telescopic sleeve rods are all arranged on the same facade, and the lengths of the two sets of first telescopic sleeve rods are the same as the lengths of the two sets of second telescopic sleeve rods.

[0009] Preferably, the adjustment mechanism includes a lower column and an upper column, the upper surface of the lower column is provided with a receiving hole for the upper column to slide into, and the cross-section of the upper column is smaller than that of the lower column.

[0010] Preferably, a locking bolt is inserted into the upper end of one side of the lower column, and multiple sets of positioning holes for threaded connection of the locking bolt are provided on one side of the upper column, with the multiple sets of positioning holes being arranged at equal intervals.

[0011] Preferably, one end of each of the two sets of first telescopic sleeve rods is fixedly connected to the side of the upper column adjacent to the positioning hole, and one end of each of the two sets of second telescopic sleeve rods is fixedly connected to the side of the lower column adjacent to the locking bolt.

[0012] Preferably, both sets of support mechanisms include a first hoop, a second hoop, and a fixing pin. One end of the first hoop is rotatably connected to one end of the second hoop via the fixing pin. The other end of the first hoop is fixedly connected to a hexagonal nut, and the other end of the second hoop is inserted with a connecting bolt that is threadedly connected to the hexagonal nut.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model mainly utilizes the cooperation between a support mechanism, an adjustment mechanism, and a protective mechanism. The support mechanism facilitates installation on filters of different specifications, while the adjustment mechanism is adjusted according to the length of the filter to adapt to it. During the adjustment process, the support points of the protective mechanism are adjusted simultaneously, thus facilitating the protection of filters of different specifications and improving the protective effect on the filter. This prevents the filter from being damaged by collisions, which could affect the internal structure and ensure the filter's efficiency in eliminating crystal points. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a disc filter for eliminating protective film crystal points, including a filter body 100, two sets of support mechanisms 200 are detachably installed on the outside of the filter body 100, and multiple sets of adjustment mechanisms 300 are arranged between the two sets of support mechanisms 200. The multiple sets of adjustment mechanisms 300 are arranged at equal angles, and a protective mechanism 400 is installed on the side of each set of adjustment mechanisms 300 opposite to the filter body 100.

[0022] The protective mechanism 400 includes a protective plate 401. A fixing block 402 is fixedly connected to the upper end of the inner side of the protective plate 401. A first telescopic sleeve rod 403 is fixedly connected to both ends of one side of the fixing block 402. A first spring 404 is sleeved on the outer side of the two sets of first telescopic sleeve rods 403. A grooved guide plate 405 is fixedly connected to the lower end of the inner side of the protective plate 401. A sliding plate 406 is slidably connected in the groove of the grooved guide plate 405. A second telescopic sleeve rod 407 is symmetrically fixedly connected to both ends of one side of the sliding plate 406. A second spring 409 is sleeved on the outer side of the two sets of second telescopic sleeve rods 407.

[0023] Two sets of first telescopic sleeve rods 403 and two sets of second telescopic sleeve rods 407 are all set on the same facade. The lengths of the two sets of first telescopic sleeve rods 403 and the two sets of second telescopic sleeve rods 407 are the same, so that the stress points of the protective plate 401 after being subjected to force are on the same plane, thereby improving the force buffering effect of collision. At the same time, the first telescopic sleeve rods 403 and second telescopic sleeve rods 407, together with the first spring 404 and the second spring 409, form a damper, thereby improving the shock absorption effect.

[0024] The adjustment mechanism 300 includes a lower column 301 and an upper column 302. The upper surface of the lower column 301 is provided with a storage hole 304 for the upper column 302 to slide into. The cross-section of the upper column 302 is smaller than that of the lower column 301. The upper column 302 can be adjusted in the storage hole 304 of the lower column 301 to accommodate filter bodies 100 of different specifications.

[0025] A locking bolt 305 is inserted into the upper end of one side of the lower column 301. The upper column 302 has multiple sets of positioning holes 303 for the locking bolt 305 to be threaded. The multiple sets of positioning holes 303 are set at equal intervals. The upper column 302 is fixed by screwing the locking bolt 305 into the positioning holes 303 at different positions, thereby improving the stability of the adjustment mechanism 300.

[0026] One end of each of the two sets of first telescopic sleeve rods 403 is fixedly connected to the side of the upper column 302 adjacent to the positioning hole 303, and one end of each of the two sets of second telescopic sleeve rods 407 is fixedly connected to the side of the lower column 301 adjacent to the locking bolt 305. The first telescopic sleeve rods 403 move up and down with the upper column 302, and the second telescopic sleeve rods 407 drive the slide plate 406 to slide in the grooved guide plate 405 to support the protective plate 401.

[0027] Both sets of support mechanisms 200 include a first hoop 201, a second hoop 203, and a fixing pin 202. One end of the first hoop 201 is rotatably connected to one end of the second hoop 203 via the fixing pin 202. The other end of the first hoop 201 is fixedly connected to a hexagonal nut 205. The other end of the second hoop 203 is inserted with a connecting bolt 204 that is threadedly connected to the hexagonal nut 205. The first hoop 201 and the second hoop 203 can be easily opened and closed via the fixing pin 202, thereby adapting to different specifications of filter bodies 100. At the same time, the connecting bolt 204 can be used to easily close and fix the first hoop 201 and the second hoop 203, improving the stability after closure.

[0028] Both the first hoop 201 and the second hoop 203 have two sets of positioning screws 206 threadedly connected to their outer sides. Each pair of positioning screws 206 has an anti-slip pad 207 fixedly connected to one end near the filter. A rotating rod 208 is fixedly connected to one end of the positioning screw 206 relative to the anti-slip pad 207. By rotating the rotating rod 208, the positioning screw 206 is driven to adjust the position of the anti-slip pad 207, thereby causing the anti-slip pad 207 to abut against the outer side of the filter body 100, improving the stability of the support.

[0029] In use, the extension length of the upper column 302 is adjusted according to the length of the filter body 100, and the upper column 302 is fixed by inserting the locking bolt 305 into the positioning hole 303. The first hoop 201 and the second hoop 203 are flipped to close, and the connection bolt 204 is screwed into the hexagonal nut 205 to complete the closure and fixation. The positioning screw 206 on the first hoop 201 and the second hoop 203 is rotated so that the anti-slip pad 207 on the positioning screw 206 abuts against the filter body 100, thereby positioning the protective mechanism 400. The protective plate 401 buffers the impact force of the collision, thereby compressing the first spring 404 and the second spring 409. The first telescopic sleeve 403 and the second telescopic sleeve 407 quickly reset the first spring 404 and the second spring 409, thereby buffering the impact force and improving the protection effect on the filter body 100, thus avoiding the impact of the collision on the filter body 100.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
