Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of mixing equipment, and in particular to a raw material crushing and tamping rod for coating production. Background Technology
[0002] In the production process of coatings, the mixing of raw materials is a crucial step, aiming to ensure that various materials are thoroughly and evenly mixed. In some coating production processes, powdered raw materials may need to be added. These powdered raw materials are susceptible to clumping or agglomeration due to moisture in the air during storage. However, most mixing rods struggle to effectively break up and separate these clumped powders during mixing, which significantly hinders the mixing effect of the coating. Utility Model Content
[0003] In order to fully break and disperse easily agglomerated powder raw materials during coating mixing and improve the mixing effect of coating, this application provides a raw material crushing and tamping bar for coating production.
[0004] The technical solution for a raw material crushing and tamping bar used in paint production provided in this application is as follows:
[0005] A raw material crushing and tamping bar for paint production includes a main rod, several support rods, and a pressing mesh. One end of each of the support rods is fixedly connected to the bottom end of the main rod, and the other end extends outwards toward the main rod and is connected to the pressing mesh.
[0006] The pressure net includes an annular frame and a net body. The end of the support rod away from the main rod is connected to the annular frame. The net body is located on the inner side of the annular frame and is composed of several crisscrossing metal pressure rods.
[0007] By adopting the above technical solution, workers can use the pressure mesh on the tamping rod to squeeze and crush the agglomerated powder raw materials, so that the agglomerated powder raw materials can be fully broken and separated, which is conducive to the full and uniform dispersion of the powder raw materials during subsequent mixing, and helps to improve the mixing effect of the subsequent coating.
[0008] Optionally, several metal pressure bars are arranged in a crisscross pattern to form several sets of rectangular meshes of uniform size in the mesh body, with the side length of a single mesh being 1-15mm.
[0009] By adopting the above technical solution, since the crushed powder material will pass through the mesh when the tamping rod squeezes the agglomerated powder material, the fineness of the crushed powder material can be initially controlled by the size of the mesh.
[0010] Optionally, a fastener is provided at the end of the support rod away from the main rod, and the fastener is engaged with the annular frame.
[0011] By adopting the above technical solution, a detachable connection between the pressure net and the support rod is achieved using snap-fit components. This not only ensures a secure connection between the pressure net and the support rod but also makes disassembly simple and convenient. Furthermore, the detachable pressure net facilitates the replacement of pressure nets with different mesh sizes or the cleaning of the pressure net.
[0012] Optionally, a connecting piece is provided at the end of the support rod away from the main rod. The annular frame includes an annular connecting part located directly below the connecting piece. The connecting piece and the annular connecting part are detachably connected by a fastening bolt and a fastening nut. The fastening bolt passes through the annular connecting part and the connecting piece sequentially from bottom to top. The fastening nut is sleeved at the end of the fastening bolt that protrudes from the connecting piece.
[0013] By adopting the above technical solution, a detachable connection between the pressure mesh and the support rod is achieved using fastening bolts and nuts. This not only ensures a complete connection between the pressure mesh and the support rod but also makes disassembly simple and convenient. Furthermore, placing the fastening nut on the side of the connecting piece away from the annular connection part allows workers to promptly detect any loosening of the fastening bolts and nuts, effectively preventing any impact on the crushing effect of the tamping rod due to incomplete fixation of the pressure mesh.
[0014] Optionally, the annular frame further includes a recessed portion located on the side of the annular connecting portion away from the connecting piece and extending in a direction away from the connecting piece. The extension length of the recessed portion is not less than the end thickness of the fastening bolt, and the mesh is disposed on the inner side of the annular portion away from the annular connecting portion.
[0015] By adopting the above technical solution, it is possible to effectively prevent the mesh from being unable to fully squeeze and crush the clumps of powder coating due to the excessive thickness of the end of the fastening bolt, which is conducive to ensuring the crushing effect of the tamping rod.
[0016] Optionally, the main rod includes an outer rod and an inner rod, the top end of the inner rod passing through the inner side of the bottom end of the outer rod, and the inner rod and the outer rod being slidably connected;
[0017] The outer rod has a threaded connection on its circumferential side at the bottom end. The abutment passes vertically through the outer rod and can abut against or release the inner rod located inside the outer rod.
[0018] By adopting the above technical solution, workers can adjust the length of the tamping rod according to the required depth of coating crushing, which helps to improve the adaptability of the tamping rod.
[0019] Optionally, a crossbar is provided at the top of the main rod, and the crossbar extends evenly toward both sides of the main rod.
[0020] By adopting the above technical solution, the crossbar can act as a handle for the tamping rod, allowing workers to hold the crossbar with both hands, which facilitates better operation and force application of the crossbar.
[0021] Optionally, both ends of the crossbar are fitted with crossbar handle sleeves, and both ends of the crossbar are provided with expansion holes.
[0022] By adopting the above technical solution, the crossbar grip sleeve can effectively increase the friction and comfort when holding the crossbar, which is conducive to the worker's full grip on the tamping rod, so as to better apply force and operate the tamping rod during the crushing process. In addition, the worker can also extend the length of the crossbar by inserting straight rods of different lengths into the extension holes at both ends of the crossbar, so as to further apply force to the tamping rod and fully break up the clumps of powder coating.
[0023] In summary, the technical solution of this application possesses at least one of the following beneficial effects:
[0024] 1. By using the pressure mesh on the tamping rod, workers can squeeze and crush the clumps of powder materials, so that the clumps can be fully broken and separated, which is conducive to the full and uniform dispersion of the powder materials during subsequent mixing, thus ensuring the mixing effect of the coating.
[0025] 2. By properly setting the size of each mesh on the pressure screen, the fineness of the crushed powder raw material can be initially controlled to ensure the mixing effect of the coating.
[0026] 3. By making the connection between the pressure net and the support rod detachable, it is convenient for workers to change pressure nets of different mesh sizes or to remove the pressure net for cleaning. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0036] Example 1
[0037] Embodiment 1 of this application discloses a raw material crushing and tamping bar for paint production. (Refer to...) Figure 1 A raw material crushing and tamping bar for paint production includes a main rod, several support rods, and a pressure mesh. One end of each support rod is connected to the bottom end of the main rod, while the other end extends outwards from the main rod and connects to the pressure mesh. Specifically, the pressure mesh includes an annular frame and a mesh body. The ends of the support rods furthest from the main rod are connected to the annular frame, and the mesh body is located inside the annular frame. The mesh body is composed of several crisscrossing metal pressure rods arranged in a crisscross pattern. This allows workers to crush and break up clumps of powder raw materials using the pressure mesh on the tamping bar, ensuring thorough breaking up and separation of the clumps. This facilitates full and uniform dispersion of the powder raw materials during subsequent mixing, ensuring effective paint mixing.
[0038] Reference Figure 1 Several crisscrossing metal pressure rods form several sets of uniformly sized rectangular meshes. Since the pulverized powder material is crushed and passes through the meshes when the rods compress it, the fineness of the crushed powder can be controlled by the size of the meshes. In this embodiment, the side length of a single mesh is 10mm, while in other embodiments, the side length of a single mesh can be selected within the range of 1-15mm depending on the required fineness of the crushed powder material.
[0039] Reference Figure 1 and Figure 2 To enable the tamping rod to crush powder coatings of varying fineness and facilitate cleaning of the pressing screen, the support rod and the pressing screen are detachably connected. Workers can disassemble the pressing screen to replace it with one of different mesh sizes or to clean it. Specifically, a locking device is installed at the end of the support rod furthest from the main rod, and this device engages with the annular frame.
[0040] Reference Figure 1In this embodiment, the main rod is a telescopic rod structure with adjustable length, allowing the operator to adjust the overall length of the main rod according to the required depth of coating mixing. In other embodiments, the main rod may be a straight rod structure with non-adjustable length. Specifically, the main rod includes an outer rod and an inner rod. The bottom end of the inner rod is connected to several support rods, and the top end of the inner rod passes through the inner side of the bottom end of the outer rod. The inner rod can slide along the inner side of the outer rod. The bottom end of the outer rod is threaded with a clamping member for fixing the inner rod. Specifically, the clamping member is vertically inserted into the inner side of the outer rod and can be tightened or loosened by rotating the thread.
[0041] When the overall length of the main rod needs to be adjusted, the operator only needs to rotate the threaded clamping part and loosen the clamping of the inner rod, so that the inner rod can slide along the inner side of the outer rod, thus achieving the adjustment of the overall length of the main rod; and after the overall length of the main rod is adjusted, the operator only needs to rotate the threaded clamping part and make it press against the inner rod, so that the inner rod is not easy to slide relative to the outer rod, thus achieving the fixation of the overall length of the main rod.
[0042] Reference Figure 1 A crossbar is installed at the end of the main rod furthest from the support rod. The main rod and the crossbar are fixedly connected at the middle. Both ends of the crossbar extend evenly towards both sides of the main rod, thus serving as a handle for the tamping rod. Workers can hold both ends of the crossbar for better force application and operation during tamping. Furthermore, crossbar handle sleeves are fitted around both ends of the crossbar to increase grip friction and improve the feel, allowing for better handling. Extension holes are provided at both ends of the crossbar, allowing workers to insert additional straight rods to extend the length of both ends, thus enabling better force application to the tamping rod.
[0043] The implementation principle of the raw material crushing and tamping rod for paint production in Embodiment 1 of this application is as follows:
[0044] When it is found that the coating contains clumps of powder material, the workers can use the pressure mesh on the tamping rod to squeeze and crush the clumps of powder material, so that the clumps of powder material can be fully broken and separated.
[0045] The detachable connection between the support rod and the pressing screen not only allows the tamping rod to replace the pressing screen with different mesh sizes according to the fineness of the powder raw material, which is beneficial to improving the tamping effect of the tamping rod, but also makes it easier for the staff to clean the pressing screen.
[0046] By rotating the screw thread, the clamping part can be tightened or loosened against the inner rod. The operator can adjust the length of the tamping rod according to the required depth of coating crushing, which helps to improve the adaptability of the tamping rod.
[0047] By installing a crossbar at the top of the tamping rod, workers can hold both ends of the crossbar with both hands, allowing for better force application and operation during the tamping process. Furthermore, workers can extend the length of the crossbar by inserting straight rods of different lengths into the extension holes at both ends, enabling them to apply even more force to the tamping rod.
[0048] Example 2
[0049] Embodiment 2 of this application discloses a raw material crushing and tamping bar for coating production, referring to... Figure 3 and Figure 4 The difference between Embodiment 2 and Embodiment 1 lies in the different structures of the annular frame and the different connection structures between the support rod and the pressure net.
[0050] Reference Figure 4 , Figure 5 and Figure 6 In this embodiment, the annular frame includes an annular connecting part and a recessed part. The annular frame is detachably connected to the support rod via the annular connecting part. Specifically, a connecting piece is provided at the end of the support rod away from the main rod. The annular connecting part is located directly below the connecting piece. The connecting piece and the annular connecting part are detachably connected by a fastening bolt and a fastening nut. The fastening bolt passes through the annular connecting part and the connecting piece sequentially from bottom to top, and the fastening nut is threaded onto the end of the fastening bolt that protrudes from the connecting piece. Thus, when the fastening bolt and the fastening nut become loose, the fastening bolt will fall off due to its own weight, which helps workers to promptly detect the connection status between the pressure mesh and the support rod and prevents the crushing effect of the tamping rod from being affected by the pressure mesh not being fully fixed.
[0051] Reference Figure 6 The recessed portion is located on the side of the annular connecting portion away from the support rod and extends in a direction away from the support rod. The length of the recessed portion extension should not be less than the end thickness of the fastening bolt. In this embodiment, the extension length of the recessed portion is specifically 5mm greater than the end thickness of the fastening bolt. The mesh body is located on the inner side of the annular portion away from the end of the recessed portion. Since the recessed portion places the mesh body below the fastening bolt, it can effectively prevent the mesh body from being unable to fully crush the clumps of powder coating due to the end of the fastening bolt being too thick, which helps to ensure the crushing effect of the tamping rod.
[0052] The implementation principle of the raw material crushing and tamping rod for paint production in Embodiment 2 of this application is as follows:
[0053] Connecting the connecting plate of the support rod and the annular connection of the pressure mesh using fastening bolts and nuts not only ensures a secure connection between the pressure mesh and the support rod but also makes disassembly simple and convenient. Furthermore, placing the fastening nut on the side of the connecting plate away from the annular connection allows workers to promptly detect any loosening of the fastening bolts and nuts, effectively preventing any impact on the crushing effect of the tamping rod due to incomplete fixation of the pressure mesh.
[0054] In addition, by placing the mesh below the fastening bolts through the recessed part, it can effectively prevent the mesh from being unable to fully squeeze and crush the clumps of powder coating due to the excessive thickness of the end of the fastening bolts, which helps to ensure the crushing effect of the tamping rod.
[0055] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this specific embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
