Description

Technical Field

[0001] This utility model relates to the field of PVC film production, specifically a horizontal filter for raw materials used in PVC film production. Background Technology

[0002] PVC film, short for polyvinyl chloride film, is a film material made from polyvinyl chloride resin as the main raw material, with the addition of plasticizers, stabilizers and other additives, through processes such as mixing, filtration, extrusion or calendering. When processing PVC film, the raw materials used need to be filtered through a horizontal filter, so that the quality of PVC film after production is higher and the performance is better. At the same time, it reduces the possibility of clogging the extruder die head or causing defects in the film material due to more impurities in subsequent processing.

[0003] In existing technologies, PVC film production requires the filtration of raw materials, and in most cases, horizontal filters are used. Generally, horizontal filters have three filter screens with progressively smaller pore sizes to filter impurities. The raw materials are usually transported by a feed pump in the horizontal filter and allowed to pass smoothly through the first filter screen. However, the second and third filter screens are in fixed positions when filtering raw materials, so they can only perform passive filtration. When encountering agglomerates or impurities clogging the pores, the filtration effect and efficiency are easily reduced, which in turn affects the subsequent production and processing efficiency of PVC film. Utility Model Content

[0004] To overcome the shortcomings of existing technology, the second and third filter screens inside the horizontal filter are in fixed positions when filtering raw materials. As a result, the second and third filter screens can only perform passive filtration. When encountering agglomerates or impurities clogging the pores, the effect and efficiency of impurity filtration are easily reduced, which in turn affects the production and processing efficiency of subsequent PVC films. This utility model proposes a horizontal filter for raw materials in PVC film production.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a horizontal filter for raw materials in PVC film production, including a feeding pump body, a filter box body fixedly connected to one side of the feeding pump body, a first filter screen, a second filter screen and a third filter screen being provided in the inner cavity of the filter box body, and an auxiliary mechanism being provided in the inner cavity of the filter box body.

[0006] The auxiliary mechanism includes a mounting plate, one side of which is fixedly connected to the inner cavity of the filter housing. A waterproof servo motor is fixedly connected to one side of the mounting plate. A drive rod is fixedly connected to the output end of the waterproof servo motor. A fixed rod and a first cam are fixedly connected to the surface of the drive rod. A fixed block is fixedly connected to the inner cavity of the filter housing. A fixed rod and a spring are fixedly connected to one side of the fixed block. A moving block is fixedly connected to one end of the spring. One side of the moving block is fixedly connected to one side of the second filter screen. The surface of the fixed rod is slidably connected to the inner cavity of the moving block. A connecting assembly is provided in the inner cavity of the filter housing. A reciprocating assembly is provided on the surface of the third filter screen.

[0007] Preferably, the reciprocating assembly includes a fixed plate, one side of which is fixedly connected to the inner cavity of the filter box. An installation rod is rotatably connected to the inner cavity of the fixed plate. A rotating disk is fixedly connected to one end of the installation rod. An installation block is fixedly connected to one side of the rotating disk. A connecting plate is rotatably connected to the surface of the installation block. A pulling rod is rotatably connected to the inner cavity of the connecting plate. One end of the pulling rod is fixedly connected to one side of the third filter screen. A limiting plate is fixedly connected to the inner cavity of the filter box. One side of the third filter screen is slidably connected to one side of the limiting plate.

[0008] Preferably, the connecting assembly includes a worm gear, the inner cavity of which is fixedly connected to the surface of the mounting rod, and the surface of the waterproof servo motor is fixedly connected to the worm gear, the teeth of which mesh with the teeth of the worm.

[0009] Preferably, a connecting rod is fixedly connected to one side of the first cam, and a second cam is fixedly connected to the surface of the connecting rod.

[0010] Preferably, a reinforcing ring is fixedly connected to one side of the third filter screen, and the inner cavity of the reinforcing ring is fixedly connected to the surface of the pull rod.

[0011] Preferably, a limiting block is fixedly connected to one side of the third filter screen, a limiting groove is formed on one side of the limiting plate, and the surface of the limiting block is slidably connected to the inner cavity of the limiting groove.

[0012] Preferably, a reinforcing ring is fixedly connected to the inner cavity of the filter housing, and the inner cavity of the reinforcing ring is rotatably connected to the surface of the connecting rod.

[0013] The advantages of this utility model are:

[0014] This invention utilizes a waterproof servo motor to simultaneously rotate a first cam and a mounting rod. The rotation of the first cam pushes the second filter screen, and in conjunction with the elasticity of the spring, achieves reciprocating movement of the second filter screen. Meanwhile, the rotation of the mounting rod drives the mounting block to rotate, which, through the connecting plate, continuously pulls and pushes the third filter screen, enabling it to also reciprocate. This results in better filtration and higher efficiency of the material inside the horizontal filter when workers need to filter PVC film raw materials. It solves the problem that in horizontal filters, the positions of the second and third filter screens are fixed, resulting in passive filtration. When encountering clumps or impurities clogging the pores, the filtration effect and efficiency are easily reduced, thus affecting the subsequent production and processing efficiency of PVC film.

[0023] 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 scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a horizontal filter press for raw materials in PVC film production. (See also...) Figure 1 and Figure 3 A horizontal filter for raw materials in PVC film production includes a feed pump body 1, a filter box 2 fixedly connected to one side of the feed pump body 1, a first filter screen 3, a second filter screen 4 and a third filter screen 5 provided in the inner cavity of the filter box 2, and an auxiliary mechanism 6 provided in the inner cavity of the filter box 2.

[0026] The auxiliary mechanism 6 includes a mounting plate 601. One side of the mounting plate 601 is fixedly connected to the inner cavity of the filter box 2. A waterproof servo motor 602 is fixedly connected to one side of the mounting plate 601. A drive rod 603 is fixedly connected to the output end of the waterproof servo motor 602. A fixing rod 604 and a first cam 605 are fixedly connected to the surface of the drive rod 603. A fixing block 608 is fixedly connected to the inner cavity of the filter box 2. A fixing rod 604 and a spring 609 are fixedly connected to one side of the fixing block 608. A moving block 610 is fixedly connected to one end of the spring 609. One side of the moving block 610 is fixedly connected to one side of the second filter screen 4. The surface of the fixing rod 604 is slidably connected to the inner cavity of the moving block 610. A connecting component 607 is provided in the inner cavity of the filter box 2. A reciprocating component 606 is provided on the surface of the third filter screen 5.

[0027] The feed pump body 1 can be connected to the filter housing 2, and the feed pump body 1 and the filter housing 2 can form an important part of the horizontal filter. Since the horizontal filter is already existing technology in this field, the working principle of the feed pump body 1 will not be elaborated here. The filter housing 2 can install and connect the first filter screen 3, the second filter screen 4, and the third filter screen 5, so that the first filter screen 3, the second filter screen 4, and the third filter screen 5 can effectively filter the raw material of PVC film. At the same time, the filter housing 2 can install and connect the waterproof servo motor 602 through the mounting plate 601, and the waterproof servo motor 602 can effectively drive the water flow during operation. Rod 603 drives the first cam 605 to rotate. The filter box 2 can also be connected to the spring 609 and the fixed rod 604 through the fixed block 608. The second filter screen 4 is sleeved and slid on the surface of the fixed rod 604 through the moving block 610. This allows the first cam 605 to effectively push the second filter screen 4 continuously and repeatedly when it rotates. The second filter screen 4 can be reset by the elasticity of the spring 609. Thus, when filtering the raw material of PVC film, the second filter screen 4 can effectively filter the agglomerated PVC film raw material through its own reciprocating movement, and reduce the raw material particles clogging the inside of the second filter screen 4.

[0028] Reference Figure 4 and Figure 5The reciprocating assembly 606 includes a fixed plate 6061, one side of which is fixedly connected to the inner cavity of the filter housing 2. A mounting rod 6062 is rotatably connected to the inner cavity of the fixed plate 6061. A rotating disk 6063 is fixedly connected to one end of the mounting rod 6062. A mounting block 6064 is fixedly connected to one side of the rotating disk 6063. A connecting plate 6065 is rotatably connected to the surface of the mounting block 6064. A pulling rod 6066 is rotatably connected to the inner cavity of the connecting plate 6065. One end of the pulling rod 6066 is fixedly connected to one side of the third filter screen 5. A limiting plate 6067 is fixedly connected to the inner cavity of the filter housing 2. One side of the third filter screen 5 is slidably connected to one side of the limiting plate 6067. The filter housing 2 can be connected to the mounting rod 6062 via the fixed plate 6061, and the mounting rod 6062 can effectively reciprocate. The rotating disk 6063 is installed, and when the mounting rod 6062 rotates, it can smoothly drive the mounting block 6064 to rotate through the rotating disk 6063. The rotation of the mounting block 6064 can rotate eccentrically around the center of the rotating disk 6063. The connection between the pull rod 6066 and the third filter screen 5 and the connecting plate 6065 allows the third filter screen 5 to reciprocate smoothly through the connecting plate 6065 and the pull rod 6066 when the mounting block 6064 rotates, thereby further improving the filtration effect when filtering raw materials. At the same time, the setting of the limiting plate 6067 can not only effectively limit the reciprocating movement of the third filter screen 5, but also reduce the raw materials flowing out from the gap between the third filter screen 5 and the filter box 2, so that the raw materials can be filtered more smoothly.

[0029] Reference Figure 5 and Figure 6 The connecting component 607 includes a worm gear 6071, the inner cavity of which is fixedly connected to the surface of the mounting rod 6062. The surface of the waterproof servo motor 602 is fixedly connected to the worm gear 6071. The teeth of the worm gear 6071 mesh with the teeth of the worm 6072. When the waterproof servo motor 602 rotates, it can smoothly drive the worm gear 6071 to rotate. The rotation of the worm gear 6071 can effectively drive the worm 6072 and the mounting rod 6062 to rotate together. This allows the second filter screen 4 and the third filter screen 5 to move synchronously to increase the filtration effect on the raw materials when the second filter screen 4 and the third filter screen 5 need to be moved to increase the filtration effect on the raw materials. This can be achieved with only a single drive source, thereby reducing energy consumption and saving costs.

[0030] Reference Figure 4 and Figure 5A connecting rod 10 is fixedly connected to one side of the first cam 605, and a second cam 11 is fixedly connected to the surface of the connecting rod 10. The first cam 605 can install and fix the second cam 11 through the connecting rod 10, while the second cam 11 can play an auxiliary role to the first cam 605, so that when the first cam 605 pushes the second filter screen 4, the second cam 11 can also push the first cam 605, thereby making the first cam 605 move more smoothly and steadily when it moves by pushing, and it is not easy for one side to move while the other side does not move.

[0031] Reference Figure 5 A reinforcing ring 9 is fixedly connected to one side of the third filter screen 5. The inner cavity of the reinforcing ring 9 is fixedly connected to the surface of the pull rod 6066. The reinforcing ring 9 can strengthen the connection between the pull rod 6066 and the third filter screen 5 by utilizing its connection with the third filter screen 5 and the pull rod 6066, so that the third filter screen 5 can move more smoothly and steadily when it reciprocates by rotating the rotating disk 6063.

[0032] Reference Figure 3 and Figure 5 A limiting block 7 is fixedly connected to one side of the third filter screen 5, and a limiting groove 8 is opened on one side of the limiting plate 6067. The surface of the limiting block 7 is slidably connected to the inner cavity of the limiting groove 8. The setting of the limiting block 7 and the limiting groove 8 can further increase the stability of the third filter screen 5 when it moves, thereby reducing the shaking and unstable movement of the third filter screen 5 during the movement caused by the rotation of the rotating disk 6063.

[0033] Reference Figure 4 and Figure 5 The inner cavity of the filter box 2 is fixedly connected with a reinforcing ring 12. The inner cavity of the reinforcing ring 12 is rotatably connected to the surface of the connecting rod 10. The reinforcing ring 12 can strengthen and support the connecting rod 10, making it less likely for the connecting rod 10 to shake or tilt during use, thus greatly increasing the stability of the connecting rod 10 during use.

[0034] Working Principle: When using this device, the operator adds the raw material to be filtered into the filter housing 2 via the feed pump 1. Then, the waterproof servo motor 602 is started. During operation, the waterproof servo motor 602 drives the first cam 605 and the worm gear 6072 to rotate synchronously via the drive rod 603. The first cam 605 continuously and repeatedly pushes the second filter screen 4, causing it to move. After the second filter screen 4 has moved, when the first cam 605 stops pushing it, the second filter screen 4 will return to its original position due to the elasticity of the spring 609. The continuous rotation of the first cam 605 achieves continuous pushing and movement of the second filter screen 4. Simultaneously, the rotation of the worm gear 6072, through its interaction with the worm wheel 6072, drives the second filter screen 4 to rotate synchronously. The engagement of 71 drives the mounting rod 6062 and the rotating disk 6063 to rotate. When the rotating disk 6063 rotates, it drives the mounting block 6064 to rotate around its own center. During the rotation, the connecting plate 6065 continuously and reciprocates the third filter screen 5, thereby achieving continuous reciprocating movement of the third filter screen 5. At this time, the raw material entering the filter box 2 will pass through the second filter screen 4, the first filter screen 3, and the third filter screen 5. The raw material will be successfully filtered when passing through the first filter screen 3, the second filter screen 4, and the third filter screen 5. The continuous reciprocating movement of the second filter screen 4 and the third filter screen 5 can greatly reduce the agglomerated raw material and the raw material stuck inside the second filter screen 4 and the third filter screen 5, thereby improving the filtration effect of the raw material.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
