Description

Technical Field

[0001] This utility model belongs to the field of metal filter element production technology, and in particular relates to a metal filter element end closing device. Background Technology

[0002] Metal filter elements are filtration components made of metal materials. They are characterized by high strength, high temperature resistance, corrosion resistance, and reusability, and are widely used in industrial, automotive, food, and pharmaceutical fields. The end-capping process is a key manufacturing step, directly affecting the filter element's sealing performance, structural strength, and service life. The end-capping method for metal filter elements (such as sintered metal, metal wire mesh, or metal fiber filter elements) needs to be selected based on its application scenario (high pressure, corrosion, vibration, etc.). Using high-temperature resistant epoxy resin, silicone, or other adhesives to fix the filter element to the end caps allows for filter element production while ensuring a tight seal. However, this method still has the following drawbacks in practical use:

[0003] During the metal filter element closing process, the filter element is directly placed into the closing equipment. Since adhesive is used for bonding, the filter element needs to be placed properly. After the filter element is closed, it needs to be manually removed by the operator. When removing it, the operator needs to touch the end cap, and the residual heat on the end cap can easily burn the operator.

[0004] Secondly, in order to press the end cap of the metal filter element onto the filter element and then install it on the end cap through the heating structure, the heating structure remains in place after installation. When the operator removes the filter element, it is easy to accidentally touch it, which may cause a safety hazard. Utility Model Content

[0005] The purpose of this utility model is to provide a metal filter element end closing device. By setting up a support component, an electric push rod and a cylinder, it solves the problems that after the end closing device is removed, the filter element operator needs to touch the end cap, which is easy to be burned by the residual heat on the end cap. In addition, after the filter element is closed, the heating structure remains in the original position, which can easily cause safety hazards.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a metal filter element end-sealing device, comprising a support assembly, electric push rods, and cylinders. The support assembly includes a support groove and an insulation sleeve. Insulation sleeves are fixed to both ends of the support groove. The support groove is arc-shaped, and the central axis of the support groove and the central axis of the insulation sleeve are on the same straight line. Two electric push rods are arranged below the support groove, and connecting rods are fixed to the telescopic ends of the two electric push rods. An arc-shaped piece is fixed to the top of each connecting rod. Cylinders are arranged at both ends of the support assembly. In operation, the support assembly supports the filter element and the end cap for sealing the filter element. The electric push rods drive the connecting rods and the arc-shaped pieces to rise. The rising of the arc-shaped pieces lifts the filter element with the sealed end in the support groove. The cylinders drive the push plate and the heating plate to weld the filter element end cap and the filter element together, thus sealing the filter element.

[0008] Furthermore, both ends of the support groove are provided with stepped openings, and the bottom of the support groove between the two stepped openings is provided with movable openings. When the support groove is in operation, the end cap is supported by the stepped openings.

[0009] Furthermore, the arc-shaped piece is movably connected within the movable opening, and the top of the arc-shaped piece is adapted to the curvature of the bottom of the support groove. After being lifted, the arc-shaped piece will push the end cap in the support groove to fit onto the filter element.

[0010] Furthermore, the support assembly also includes an outer support plate, legs, and a base. The outer support plate is fixed at the edges of the support groove near both ends. Each outer support plate has a leg symmetrically fixed on its outer arc surface. The bottom of all the legs is fixed to the base. The bottom of each electric push rod is fixed to the top of the base. When the support assembly is in operation, the legs on the outer support plate support the outer support plate and the support groove on the base, and the base supports them on the workbench.

[0011] Furthermore, each cylinder is fixed to a support at its bottom, the two cylinders are arranged symmetrically to each other, and the extension and retraction ends of the cylinders are all facing the support groove. When the cylinder is working, it is supported on the worktable by the support.

[0012] Furthermore, each cylinder has a push plate fixed to its telescopic end, and a heating plate fixed to the end of the push plate away from the cylinder. The push plate and heating plate of the same cylinder telescopic end are respectively sleeved in the heat insulation sleeve close to the cylinder. The cylinder drives the heating plate to move by pushing the push plate until the heating plate presses against the filter element end cover in the support groove, pressing the filter element end cover onto the filter element.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of operators being easily burned by the residual heat of the end cap when the end cap of the metal filter element is removed, by setting up a support component and an electric push rod. After the filter element is closed, the electric push rod is activated, which drives the connecting rod to rise, thereby raising the arc-shaped plate. The rising arc-shaped plate raises the filter element in the support groove, which is now closed and has the end cap installed, until it leaves the support groove. At this point, the middle of the filter element can be directly grasped and removed, preventing burns to the operator from the residual heat of the filter element end and increasing safety during use.

[0015] This invention solves the safety hazard problem of the heating structure remaining in place after the metal filter element is closed by setting up a support component and cylinders. When the filter element and its end cap are placed in the support groove, two cylinders are activated. The two cylinders push the push plate, which in turn moves the heating plate. The heating plate is pushed to contact the filter element end cap in the stepped opening, and then pushes the filter element end cap to both ends of the filter element in the support groove. This causes the end cap to press against both ends of the filter element. After the heating plate heats the filter element, the end cap and the filter element are welded together. After completion, the cylinders are restarted, and the cylinders drive the push plate, which moves the heating plate into the insulation sleeve. By placing the heating plate inside the insulation sleeve, the operator is prevented from being burned by contacting the heating plate when removing the filter element, thus increasing the safety of operation.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0025] Please see Figure 1-4 This utility model relates to a metal filter element end-closing device, comprising a support assembly 1, electric push rods 2, and a cylinder 3. The support assembly 1 includes a support groove 101 and an insulation sleeve 105. Insulation sleeves 105 are fixed to both ends of the support groove 101. The support groove 101 is arc-shaped, and its central axis and the central axis of the insulation sleeve 105 are collinear. When the support groove 101 is in operation, it fixes the insulation sleeve 105 to it. The insulation sleeve 105 stores the heating plate 303 when not in operation to prevent burns to workers. Two electric push rods 2 are located below the support groove 101. The telescopic ends of push rod 2 are all fixed with connecting rods 201. The electric push rod 2 drives the connecting rods 201 to rise and fall, which in turn drives the arc-shaped plate 202 to rise and fall. During the rise and fall of the arc-shaped plate 202, the filter element supported in the support groove 101 is pushed to rise and fall. The top of each connecting rod 201 is fixed with an arc-shaped plate 202. When the arc-shaped plate 202 is working, it cooperates with the support groove 101 to support the filter element being processed on it. The top curvature of the arc-shaped plate 202 is consistent with the arc-shaped contour of the bottom of the support groove 101, ensuring that the filter element is subjected to uniform force when it is lifted. Both ends of the support assembly 1 are equipped with cylinders 3. The cylinders 3 drive the push plate 302 and the heating plate 303 to move.

[0026] Specifically, both ends of the support groove 101 are provided with stepped openings 1011, and the bottom of the support groove 101 between the two stepped openings 1011 is provided with movable openings 1012. When the support groove 101 is working, the filter element end cap coated with hot melt adhesive is movably connected through the stepped openings 1011.

[0027] Furthermore, the arc-shaped plate 202 is movably connected within the movable opening 1012, and the top of the arc-shaped plate 202 is adapted to the curvature of the bottom of the support groove 101. By entering the movable opening 1012 and adapting to the bottom of the support groove 101, the arc-shaped plate 202 provides support for the filter element during operation. After the filter element is closed, it pushes the filter element upward, allowing the operator to hold the unheated part in the middle of the filter element, thus increasing work safety.

[0028] Furthermore, the support assembly 1 also includes an outer support plate 102, a support leg 103, and a base 104. The outer support plate 102 is fixed at the edges of the support groove 101 near both ends. The support leg 103 is symmetrically fixed on the outer arc surface of each outer support plate 102. The base 104 is fixed to the bottom of all the support legs 103. The bottom end of each electric push rod 2 is fixed to the top of the base 104. The outer support plate 102 on the support groove 101 is connected to the support leg 103 and supported on the base 104, and supported on the working plane by the base 104.

[0029] The operation process of this embodiment is as follows: During operation, the filter element that needs to be closed is placed in the support groove 101, and both ends are placed in the two stepped openings 1011 respectively. The openings of the two end caps of the filter element face the filter element and are placed in the two stepped openings 1011 respectively. The filter element can be closed and the end caps installed. After the filter element is closed, the electric push rod 2 is started. The electric push rod 2 drives the connecting rod 201 to rise, which drives the arc plate 202 to rise. Through the rise of the arc plate 202, the filter element with the closed end caps installed in the support groove 101 is lifted to leave the support groove 101. At this time, the middle part of the filter element can be directly grasped and the filter element can be removed to prevent the operator from being burned by the residual heat after the end of the filter element is heated. Specific Implementation Example 2

[0030] Please see Figure 1 , 2 5. Based on the specific embodiment one, each cylinder 3 has a support 301 fixed at its bottom. The two cylinders 3 are arranged symmetrically to each other, and the extension and retraction ends of the cylinders 3 are all set towards the support groove 101. When the cylinders 3 are working, they are supported on the working plane by the support 301.

[0031] Specifically, each cylinder 3 has a push plate 302 fixed at its telescopic end, and a heating plate 303 fixed at the end of the push plate 302 away from the cylinder 3. The push plate 302 and the heating plate 303 at the telescopic end of the same cylinder 3 are respectively sleeved in the heat insulation sleeve 105 close to the cylinder 3. When the cylinder 3 is working, the push plate 302 is activated, which drives the heating plate 303 to move.

[0032] The operation process of this embodiment is as follows: During operation, after the filter element and the end cap of the filter element are placed in the support groove 101, two cylinders 3 are started. The two cylinders 3 push the push plate 302, which drives the heating plate 303 to move. This causes the heating plate 303 to be pushed to the filter element end cap in the contact step 1011, and pushes the filter element end cap to both ends of the filter element in the support groove 101. This causes the end cap to press against both ends of the filter element. After the heating plate 303 heats the filter element, the end cap and the filter element are welded together. After completion, the cylinders 3 are restarted. The cylinders 3 drive the push plate 302, which drives the heating plate 303 to move into the insulation sleeve 105. The heating plate 303 is set inside the insulation sleeve 105 and then completely retracts into the insulation sleeve 105 to avoid exposure and prevent the operator from being burned when touching the heating plate 303 when removing the filter element.
