Description

Technical Field

[0001] This utility model relates to the field of screen changer technology, and in particular to a high-efficiency filter screen changer. Background Technology

[0002] In the extrusion molding process of polymer materials such as plastics and rubber, the screen changer is a key piece of equipment, mainly used to filter impurities in the raw materials to ensure product quality. Its core component, the filter screen, is prone to clogging after long-term use and needs to be replaced regularly. Therefore, the filter screen replacement efficiency directly affects the continuity of production and processing costs.

[0003] Existing screen changers often rely on bolts, clips, or multiple sets of knobs for fixing the filter screen. For example, patent application number 202122317354.7 discloses a sealing screen changer that uses multiple knobs on the side of the screen changer. Rotating the knobs moves a positioning rod to fix and unlock the filter screen. While this structure meets basic sealing and fixing requirements, in actual use, multiple knobs need to be distributed on both sides of the screen changer. Each knob must be rotated to unlock when changing the filter screen, and then rotated in the opposite direction to lock it after replacement. This requires repeated operations for each screen change, which is not only time-consuming but also prone to causing the filter screen to be loosely fixed due to inconsistent operation sequence or force, increasing the risk of filter screen displacement and leakage in subsequent production. Utility Model Content

[0004] This invention proposes a high-efficiency filter screen changer to solve the problems of existing screen changers requiring multiple unlocking and locking operations when replacing the filter screen, resulting in numerous repetitions and long processing times for each screen replacement, and the filter screen not being securely fixed due to inconsistent operation sequence or force.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency filter screen changer, comprising a screen changer body, a sliding plate being provided inside the screen changer body, a filter screen being detachably mounted on the sliding plate, and further comprising:

[0006] The switching component includes a blocking part and a switching part, both of which are disposed within the slide plate and located near the feed end of the screen changer body. The switching part is used to drive the blocking part to switch states, so that the blocking part can quickly block the filter screen or release the block.

[0007] A push-pull component, connected to the switching part, is used to apply a driving force to the switching part.

[0008] Preferably, the blocking portion includes movable baffles located at the upper and lower ends, and the slide plate has a second receiving groove for accommodating the movable baffles.

[0009] Preferably, the switching part includes:

[0010] A protrusion is fixed to the movable stop bar, and a through groove is formed on the protrusion.

[0011] A triangular plate, fixed to the push-pull member, presses against the protrusion through the through-slot of the push-pull member to make the movable stop bar rise and fall;

[0012] A first receiving groove is formed inside the slide plate, and the triangular plate is located inside the first receiving groove.

[0013] Preferably, the push-pull member includes:

[0014] Two push-pull strips pass through corresponding slots, and the triangular plate is fixed on the push-pull strips;

[0015] A grip strip is attached to the outer ends of the two push-pull strips.

[0016] Preferably, it also includes a hydraulic rod, the output end of which is connected to the slide plate.

[0017] Preferably, the slide plate has an installation groove for installing the filter screen, and a fixed baffle is fixed inside the installation groove and near the discharge end. The fixed baffle and the movable baffle cooperate to limit the position of the filter screen.

[0018] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0019] (1) When the filter needs to be replaced, no additional tools are needed. Simply push the push bar with the grip bar to cause the triangular plate to squeeze the protrusion, which will allow the movable stop bar to rise and fall to remove the obstruction of the filter. Then you can take out the old filter and replace it with a new filter. After the replacement is completed, pull the push bar back, and the movable stop bar will block the new filter again. The whole replacement process is simple to operate. Unlocking or locking can be completed in one operation, which greatly shortens the time spent on replacing the filter and improves the efficiency of filter replacement.

[0020] (2) The blocking part and the switching part of the switching component are both located inside the slide plate and close to the feed end. The relevant parts of the push-pull component are also arranged around the slide plate. The components are closely matched and do not require much extra space, making the overall structure of the screen changer more compact. Attached Figure Description

[0030] 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.

[0031] like Figures 1-5 As shown, a high-efficiency filter screen changer includes a screen changer body 1 and a hydraulic rod 2. The internal part has a sliding cavity adapted to the slide plate 3. The output end of the hydraulic rod 2 is connected to the slide plate 3. A filter screen 4 is detachably mounted on the slide plate 3. Specifically, an installation groove 31 for mounting the filter screen 4 is opened on the slide plate 3. A fixing baffle 32 is fixed inside the installation groove 31 and near the discharge end. A high-temperature resistant sealing ring is provided at the edge of the filter screen 4. The outer wall of the sealing ring can fit tightly with the sliding cavity.

[0032] Secondly, the high-efficiency filter screen changer also includes a push-pull component 5 and a switching component 6. The switching component 6 includes a blocking part and a switching part, both of which are set inside the slide plate 3 and located near the feed end of the screen changer body 1. The switching part is used to drive the blocking part to switch states, so that the blocking part can quickly block the filter screen 4 or release the block. The push-pull component 5 is connected to the switching part and is used to apply driving force to the switching part. After the blocking part blocks the filter screen 4, it can ensure the stability of the filter screen 4 installation and prevent displacement. After the block is released, the filter screen 4 can be removed for replacement.

[0033] Among them, see Figure 3 and Figure 4 As shown, the blocking part includes movable baffles 61 located at the upper and lower ends. The slide plate 3 has a second receiving groove 65 for accommodating the movable baffles 61. The movable baffles 61 can be raised and lowered within the second receiving groove 65. The fixed baffles 32 cooperate with the movable baffles 61 to limit the filter screen 4, so as to ensure the stability of the filter screen 4 after installation.

[0034] See Figure 3 and Figure 4 As shown, the switching section includes:

[0035] The protrusion 62 is fixed on the movable stop bar 61, and the protrusion 62 has a through groove 621. A spring is connected to one end of the through groove 621 near the movable stop bar 61.

[0036] Triangle plate 63 is fixed on push-pull member 5. Push-pull member 5 passes through through slot 621 to squeeze protrusion 62, so that movable stop bar 61 rises and falls.

[0037] The first receiving slot 64 is opened inside the slide plate 3, and the triangular plate 63 is located inside the first receiving slot 64.

[0038] See Figure 2 and Figure 3 As shown, the push-pull component 5 includes a push-pull strip 51 and a grip strip 52. There are two push-pull strips 51, and the two push-pull strips 51 pass through the corresponding through slots 621 respectively. A guide slot is provided in the slide plate 3 to accommodate the movement of the push-pull strips 51. A triangular plate 63 is fixed on the push-pull strip 51 and can pass through the through slots 621. The grip strip 52 is connected to the outer ends of the two push-pull strips 51.

[0039] Based on the above, in actual use, filtration is achieved by using the filter screen 4 on the slide plate 3 inside the screen changer body 1;

[0040] When filter screen 4 reaches its usage limit and needs replacement, first use hydraulic rod 2 to move slide plate 3 outward to expose filter screen 4. Then, hold handle 52 and push push bar 51. Push bar 51 moves triangular plate 63, causing triangular plate 63 to enter through groove 621 on protrusion 62. Triangular plate 63 can squeeze the inner wall of through groove 621, causing movable stop bar 61 to move away from the center of mounting groove 31, thus removing the obstruction. At this time, the operator can quickly remove filter screen 4 and replace it with a new filter screen 4. Afterward, pull push bar 51 back to allow movable stop bar 61 to move away from the center of mounting groove 31. 61. Move the second receiving slot 65 out to block the new filter screen 4. Finally, retract the hydraulic rod 2 to return the slide plate 3 to its original position. Compared with traditional bolt fixing and buckle clamping methods, this structure can quickly achieve fixation without complicated disassembly and assembly. It can be unlocked or locked in one operation. The whole process does not require tool assistance and can be completed manually by the staff, which greatly shortens the time spent on each replacement. Secondly, the core components (push-pull bar 51, triangular plate 63, movable stop bar 61, etc.) are all arranged around the slide plate 3 and the mounting slot 31, without occupying too much extra space.

[0041] To increase the stability of the movable stop bar 61 in the blocking position, a rubber pad can be provided on the push bar 51. The rubber pad is squeezed in the guide groove that accommodates the push bar 51, so that the push bar 51 will not shift under the action of a certain external force.

[0042] In addition, a limiting set screw is also provided to press the push-pull strip 51. The limiting set screw is screwed into the guide groove from the outer wall of the slide plate 3 to press the push-pull strip 51.

[0043] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
