Description

Technical Field

[0001] This utility model relates to the field of filter screen processing technology, specifically to a water pump filter screen manufacturing equipment. Background Technology

[0002] In water pump operation, the filter screen plays a crucial role, especially in industrial applications handling molten materials. Filter screens are typically made of metal wire mesh with varying mesh counts. Mesh count refers to the number of openings per inch of length; a higher mesh count means smaller openings and stronger filtration capacity. Metal wire mesh is often chosen for its durability and high-temperature resistance. The primary function of the filter screen is to filter molten material flows by increasing the resistance to the flow, thus capturing and removing mechanical impurities such as metal particles and dust. This protects the water pump and subsequent processing equipment from damage, ensuring the purity of the material and the quality of the product. Cutting is a critical step in filter screen manufacturing. This step requires precise cutting to the required size and shape using appropriate tools and techniques, based on the specific application requirements. Common cutting methods include mechanical cutting, laser cutting, or plasma cutting, which ensure clean cut edges and the integrity of the filter screen. After cutting, the filter screen may require further processing, such as deburring, cleaning, or coating, to improve its durability, corrosion resistance, and filtration efficiency.

[0003] Extensive searching revealed CN220498110U, which discloses a filter screen processing device. Its technical solution includes a lifting frame, a hydraulic cylinder, and a processing table. Roller frames are symmetrically fixedly installed on both sides of the upper surface of the processing table. Rotary rollers are rotatably installed inside each of the two roller frames. A fixed frame is fixedly installed near the rear surface of the upper surface of the processing table. A hydraulic cylinder is fixedly installed on the upper surface of the fixed frame. The output shaft of the hydraulic cylinder is fixedly connected to the lifting frame. Pressure rollers are symmetrically rotatably installed on both sides inside the lifting frame. An electric slide is fixedly installed on the top of the inner wall of the lifting frame, and a laser cutting head is fixedly installed on the sliding end of the electric slide.

[0004] The above-mentioned method facilitates the fixing of the filter screen and improves the cutting efficiency of the filter screen. However, when cutting and processing some filter screens with relatively hard texture, due to their hard texture, a certain degree of protrusion will appear in the middle section during transportation. This makes it difficult to effectively control the cutting depth during laser cutting, resulting in some protruding positions being difficult to cut effectively. Therefore, a water pump filter screen manufacturing equipment is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a water pump filter screen manufacturing equipment, which has the advantage of pressing and shaping the hard filter screen blank to avoid the middle bulge during transportation. This solves the problem that the filter screen blank bulges in the middle due to its hardness during transportation, which makes it difficult to accurately control the cutting depth during laser cutting.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water pump filter screen manufacturing equipment, comprising a feeding mechanism, a guiding mechanism movably mounted on the top of the feeding mechanism via a longitudinal telescopic rod, and a cutting mechanism fixedly mounted on the top of the guiding mechanism; the feeding mechanism includes a base frame, with transmission rollers rotatably mounted at the front and rear ends of the top of the base frame, and a first guide frame movably mounted on one side opposite to the two transmission rollers, with first guide wheels rotatably mounted at equal intervals on the first guide frame, and support plates movably mounted on both sides inside the base frame; the two support plates are movably connected to the base frame via transverse telescopic rods, and the upper surfaces of the two support plates are on the same plane as the upper surfaces of the first guide wheels; the guiding mechanism includes a top frame, with driven rollers rotatably mounted at the front and rear ends of the bottom of the top frame, and a second guide frame movably mounted on one side opposite to the two driven rollers, with second guide wheels rotatably mounted at equal intervals on the second guide frame.

[0007] Preferably, the rear ends of the two drive rollers pass through the base frame, and pulleys are fixedly mounted on the rear ends of both drive rollers. The two pulleys are connected by a drive belt. Grooves for inserting the drive motor shaft are provided at the rear ends of both drive rollers, and diamond-shaped anti-slip textures are formed on the outer walls of both drive rollers. In this design, the drive rollers are connected to the drive belt via pulleys. This design provides stable transmission efficiency and reduces energy loss. The grooves at the rear ends of the drive rollers allow for flexible insertion of the drive motor shaft, facilitating installation and adjustment. The diamond-shaped anti-slip textures on the outer walls of the drive rollers increase friction with the material, preventing the material from sliding or shifting during transport.

[0008] Preferably, the first guide wheel is made of soft rubber, and its upper surface is on the same plane as the upper surface of the transmission roller. The use of soft rubber for the first guide wheel allows it to adapt to materials of varying hardness, reducing damage to the material surface. The fact that the upper surface of the first guide wheel is on the same plane as the upper surface of the transmission roller ensures that the material remains flat during transport, minimizing wrinkles or deformation.

[0009] Preferably, each of the two lateral telescopic rods has a connecting frame fixedly installed at the end opposite to the support plate, and the bottom of the two connecting frames is fixedly connected to both sides of the base frame. The fixed installation of the lateral telescopic rods and connecting frames in this design provides additional structural stability, preventing the support plate from easily swaying during transport.

[0010] Preferably, both driven rollers have diamond-shaped anti-slip patterns on their outer walls, and the lower ends of both driven rollers are on the same plane as the lower ends of the second guide wheel. The diamond-shaped anti-slip patterns on the outer walls of the driven rollers are similar to those on the drive rollers, providing a consistent anti-slip effect. The fact that the lower ends of the driven rollers and the lower ends of the second guide wheel are on the same plane ensures the synchronicity and stability of the material during transport.

[0011] Preferably, the second guide wheel is made of soft rubber, and its installation position matches that of the first guide wheel. The design of the second guide wheel using soft rubber, similar to the first guide wheel, further protects the material from damage. The matching installation position of the second guide wheel with the first guide wheel ensures the consistency and accuracy of the material during transport and provides a certain degree of clamping effect on the middle section of the material.

[0012] Preferably, the cutting mechanism includes a base plate, a controller fixedly mounted on the upper surface of the base plate, and support rods fixedly mounted at equal intervals on the lower surface of the base plate. The base plate is fixedly mounted on the upper surface of the first guide frame via the support rods. Laser cutting heads are fixedly mounted at equal intervals on both sides of the support rods, and the laser cutting heads are electrically connected to the controller. The cutting mechanism is equipped with a controller, enabling precise control of the cutting process. The fixed mounting of the base plate via the support rods provides good stability and reduces vibration during the cutting process. The electrical connection between the laser cutting heads and the controller enables efficient and precise cutting, improving production efficiency and product quality.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention features a support plate that is movably connected to the base frame via a transverse telescopic rod. This allows for adjustment based on the width of the filter screen blank, accommodating screen blanks of different sizes. This design helps to evenly support the entire screen blank, reducing the possibility of central bulges. The upper surface of the support plate is flush with the upper surface of the first guide wheel, ensuring the screen blank remains flat during transport. The equidistant rotation of the first and second guide wheels further guarantees the stability of the screen blank during transport. The outer wall of the transmission roller has diamond-shaped anti-slip textures, which helps increase friction with the screen blank and prevents it from sliding during transport. The material guide mechanism, including a top frame, driven rollers, second guide frame, and second guide wheel, works together to provide stable guidance and support for the wire blank, reducing deformation caused by its hardness. The longitudinal telescopic rod allows the material guide mechanism to be adjusted vertically to accommodate wire blanks of different thicknesses, ensuring that appropriate pressure is applied to the wire blank during conveying and avoiding central bulges. The design of the entire feeding and guiding mechanism provides a stable platform, enabling the stability and accuracy of the conveying and cutting process even when handling hard wire blanks.

[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] Example 1

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, one embodiment of the present invention is a water pump filter screen manufacturing equipment, including a feeding mechanism 1, a guiding mechanism 2 movably mounted on the top of the feeding mechanism 1 via a longitudinal telescopic rod 4, and a cutting mechanism 3 fixedly mounted on the top of the guiding mechanism 2.

[0023] The feeding mechanism 1 includes a base frame 12, with transmission rollers 6 rotatably mounted at the front and rear ends of the top of the base frame 12, and a first guide frame 7 movably mounted on one side of the two transmission rollers 6, with first guide wheels 11 rotatably mounted at equal intervals on the first guide frame 7, and support plates 8 movably mounted on both sides inside the base frame 12.

[0024] The two support plates 8 are movably connected to the base frame 12 via transverse telescopic rods 10, and the upper surfaces of the two support plates 8 are on the same plane as the upper surface of the first guide wheel 11.

[0025] The material guiding mechanism 2 includes a top frame 13, with driven rollers 14 rotatably mounted at the front and rear ends of the bottom of the top frame 13, and a second guide frame 15 movably mounted on the opposite side of the two driven rollers 14, with second guide wheels 16 rotatably mounted on the second guide frame 15 at equal intervals.

[0026] Specifically, by setting a support plate 8 and movably connecting it to the base frame 12 via a transverse telescopic rod 10, the width of the filter screen blank can be adjusted to accommodate screen blanks of different sizes. This design helps to evenly support the entire screen blank and reduces the possibility of a central bulge. The upper surface of the support plate 8 is on the same plane as the upper end face of the first guide wheel 11, ensuring that the screen blank remains flat during transport. The equidistant rotation of the first guide wheel 11 and the second guide wheel 16 further ensures the stability of the screen blank during transport. The outer wall of the transmission roller 6 is provided with diamond-shaped anti-slip texture, which helps to increase the friction with the screen blank and prevent the screen blank from sliding or slipping during transport. The material guide mechanism 2, including a top frame 13, a driven roller 14, a second guide frame 15, and a second guide wheel 16, works together to provide stable guidance and support for the wire blank, reducing deformation caused by its hardness. The longitudinal telescopic rod 4 allows the material guide mechanism 2 to be adjusted in the vertical direction to accommodate wire blanks of different thicknesses, ensuring that appropriate pressure is applied to the wire blank during conveying and avoiding central bulges. The design of the entire feeding mechanism 1 and the material guide mechanism 2 provides a stable platform, enabling the stability and accuracy of the conveying and cutting process to be maintained even when handling wire blanks with hard textures.

[0027] Example 2

[0028] To ensure stability during the conveying of the filter screen blank, such as Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the rear ends of the two drive rollers 6 pass through the base frame 12 respectively. Pulleys are fixedly mounted on the rear ends of both drive rollers 6, and the two pulleys are connected by a drive belt 5. Grooves for inserting the drive motor drive shaft are provided on the rear ends of both drive rollers 6, and diamond-shaped anti-slip textures are provided on the outer walls of both drive rollers 6. The design of connecting the drive rollers 6 to the pulleys and drive belt 5 provides stable transmission efficiency and reduces energy loss. The grooves at the rear ends of the drive rollers 6 allow for flexible insertion of the drive motor drive shaft, facilitating installation and adjustment. The diamond-shaped anti-slip textures on the outer walls of the drive rollers 6 increase friction with the material, preventing the material from sliding or shifting during transport.

[0029] Furthermore, the first guide wheel 11 is designed with soft rubber material, and the upper surface of the first guide wheel 11 is on the same plane as the upper surface of the transmission roller 6. The design of the first guide wheel 11 using soft rubber material can adapt to materials of different hardness, reducing damage to the material surface. The fact that the upper surface of the first guide wheel 11 is on the same plane as the upper surface of the transmission roller 6 ensures that the material remains flat during the conveying process, reducing wrinkles or deformation.

[0030] Furthermore, connecting brackets 9 are fixedly installed at the ends of the two transverse telescopic rods 10 away from the support plate 8, and the bottoms of the two connecting brackets 9 are fixedly connected to the two sides of the base frame 12 respectively. The fixed installation of the transverse telescopic rods 10 and the connecting brackets 9 in the design provides additional structural stability, making it less likely for the support plate 8 to shake during transportation.

[0031] Furthermore, both driven rollers 14 have diamond-shaped anti-slip patterns on their outer walls, and the lower ends of both driven rollers 14 are on the same plane as the lower ends of the second guide wheel 16. The diamond-shaped anti-slip patterns on the outer walls of the driven rollers 14 are similar to those on the drive roller 6, providing a consistent anti-slip effect. The fact that the lower ends of the driven rollers 14 and the second guide wheel 16 are on the same plane ensures the synchronicity and stability of the material during transport.

[0032] Furthermore, the second guide wheel 16 is made of soft rubber, and its installation position matches that of the first guide wheel 11. The design of the second guide wheel 16, using soft rubber similar to the first guide wheel 11, further protects the material from damage. The matching installation position of the second guide wheel 16 with the first guide wheel 11 ensures the consistency and accuracy of the material during transport and provides a certain degree of clamping effect on the middle section of the material.

[0033] Example 3

[0034] To ensure that the width of the finished product is adjustable and controllable during the cutting of the filter screen blank, such as... Figure 4 As shown, in this embodiment, the cutting mechanism 3 includes a base plate 18. A controller 17 is fixedly installed on the upper surface of the base plate 18, and support rods 19 are fixedly installed at equal intervals on the lower surface of the base plate 18. The base plate 18 is fixedly installed on the upper surface of the first guide frame 7 via the support rods 19. Laser cutting heads 20 are fixedly installed at equal intervals on both sides of the support rods 19, and the laser cutting heads 20 are electrically connected to the controller 17. The cutting mechanism 3 is equipped with a controller 17, which enables precise control of the cutting process. The fixed installation of the base plate 18 via the support rods 19 provides good stability and reduces vibration during the cutting process. The electrical connection between the laser cutting heads 20 and the controller 17 enables efficient and precise cutting, improving production efficiency and product quality.

[0035] When using this utility model, the filter screen blank to be cut is placed on one side of the feeding mechanism 1, with one end positioned above a transmission roller 6. The drive shaft of the drive motor is inserted into the groove at the rear end of the transmission roller 6. The distance between the base frame 12 and the top frame 13 is adjusted by the longitudinal telescopic rod 4 to ensure that the diamond-shaped anti-slip texture of the transmission roller 6 can stably grip and transport the filter screen blank. Simultaneously, the position of the support plate 8 is adjusted according to the width of the filter screen blank to ensure that its upper surface is on the same plane as the upper end surface of the first guide wheel 11, ready for feeding. The drive motor is started to transport the filter screen blank forward through the rotation of the transmission roller 6. At this time, the middle section of the filter screen blank is clamped and positioned by the first guide wheel 11 and the second guide wheel 16 to avoid the middle bulge during the force process. The required cutting parameters, including cutting speed and cutting depth, are set on the controller 17 of the cutting mechanism 3. The laser cutting head 20 is selected at an appropriate position according to the required forming width and started, so as to accurately cut the filter screen blank according to the preset parameters. During the cutting process, the cutting quality is continuously monitored to ensure that the cutting edges are neat and meet the requirements. Once the filter screen blank is completely cut into the required size and shape, the cutting mechanism 3 and the guiding mechanism 2 are stopped. Afterwards, the cut filter screen is inspected and processed, such as deburring and cleaning.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
