Description

Technical Field

[0001] This application relates to the field of coating treatment technology, specifically to a coating degreasing pretreatment device. Background Technology

[0002] In the coating process, before coating, the workpiece will be contaminated with oil, dust, metal shavings and other impurities after cutting, stamping and other processes. If the impurities are not removed, they will damage the coating interface. Oil will form an isolation layer, which will reduce the adhesion of the coating and make it easy to crack and peel off. Dust and other particles will embed in the coating, affecting the appearance and reducing the coating performance and shortening the life of the workpiece. Therefore, the pretreatment equipment for degreasing before coating is particularly important.

[0003] For example, patent CN221211154U discloses a pretreatment device for coating degreasing, which includes a processing machine housing, a guide frame plate, a bidirectional extrusion screw, and an extrusion adjustment mechanism. The beneficial effect of this invention is that it can adjust the extrusion pressure of two velvet polishing discs on the cylindrical workpiece before coating degreasing; increasing the extrusion pressure improves the cleaning and removal effect on the cylindrical workpiece before coating degreasing.

[0004] However, the aforementioned pretreatment equipment for degreasing in coatings mainly relies on the squeezing and cleaning action of a cloth polishing disc to achieve degreasing and impurity removal. During the squeezing and cleaning process, dust and processing residue adhering to the workpiece surface will be detached due to the friction of the polishing disc. This detached dust and residue are not easily collected in time. On the one hand, they accumulate inside the machine casing, making subsequent workpieces susceptible to secondary contamination and reducing the overall cleaning effect. On the other hand, some dust will diffuse into the surrounding environment with the airflow generated during equipment operation, potentially posing a respiratory health hazard to operators. Therefore, it is necessary to provide a pretreatment equipment for degreasing in coatings to solve these problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0006] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a pretreatment device for degreasing coatings, which solves the problem that the pretreatment device for degreasing coatings in the above-mentioned patents relies solely on the squeezing of a cloth polishing disc for cleaning, making it difficult to collect the dust and debris that are rubbed off in a timely manner, thus leading to secondary pollution of the workpiece, reduced cleaning effect, and harm to the respiratory health of workers.

[0007] The technical solution adopted by this application to solve its technical problem is: a pretreatment device for degreasing during coating, comprising: desktop; A polishing assembly, mounted on the tabletop, includes a movable adapter on which a power-driven and rotatable cleaning disc is mounted for pre-cleaning workpieces. The lower dust cover is installed on the desktop and covers the cleaning area of ​​the cleaning tray. The desktop is equipped with a waste collection box that can generate negative pressure suction, which is suitable for adsorbing dust and debris generated inside the lower dust cover.

[0008] Furthermore, the polishing assembly also includes a fixed base mounted on the desktop, a drive motor mounted on the fixed base, the output end of the drive motor extending into the fixed base and coaxially mounted with a bidirectional lead screw, the shaft of the bidirectional lead screw being fitted with a slider that can slide along the fixed base, and the adapter seat being mounted on the slider.

[0009] Furthermore, a polishing motor and a protective shell are respectively installed on the adapter. The output end of the polishing motor extends into the protective shell and is coaxially mounted with a rotating shaft. One end of the rotating shaft passes through the protective shell and is connected to the cleaning disc.

[0010] Furthermore, a polishing disc located inside the protective housing is mounted on the rotating shaft.

[0011] Furthermore, the desktop is provided with a dust collection hole corresponding to the axis of the lower dust cover, and an assembly box corresponding to the axis of the dust collection hole is installed on the desktop, with the waste collection box slidably installed inside the assembly box.

[0012] Furthermore, a vacuum cleaner is installed on the desktop, and an air vent is installed at the air intake of the vacuum cleaner, with one end of the air vent connected to the waste collection box.

[0013] Furthermore, a filter screen is installed inside the waste collection box.

[0014] The beneficial effects of this application are: the pretreatment equipment for degreasing in coating provided by this application pre-cleans the workpiece through the cleaning disc of the polishing component, and with the lower dust cover and the waste collection box that can generate negative pressure suction, it can effectively collect the dust and debris generated during the cleaning process, reduce its diffusion and pollution of the environment, wear on equipment and secondary pollution of the workpiece, thus ensuring the cleaning effect and protecting the operating environment.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] like Figures 1-4 As shown, this application provides a pretreatment equipment for coating degreasing, including a frame 1, and a table 11 is installed on the upper part of the frame 1. The table 11 is made of wear-resistant and corrosion-resistant plate and is fastened to the frame 1 by bolts.

[0021] A guide assembly 2 is installed on the desktop 11. The guide assembly 2 includes two sets of brackets 21 bolted to the upper surface of the desktop 11. The two sets of brackets 21 are symmetrically distributed and arranged at the beginning and end of the workpiece conveying path, respectively, to form a bidirectional positioning support for the workpiece, ensuring that the workpiece always moves along the preset path during the conveying process. A guide motor 22 is bolted to the outer wall of one side of the bracket 21. A main guide roller 23 is coaxially mounted on the output end of the guide motor 22. The guide motor 22 is a servo motor with speed control and torque output capabilities. Its output end is connected to the main guide roller 23 through a coupling, which can control the rotation speed of the main guide roller 23.

[0022] Specifically, the guide motor 22 is electrically connected to the equipment's PLC controller. The controller has a built-in dedicated control program that can adjust the speed of the guide motor 22 in real time according to the workpiece material, diameter, and polishing process requirements, thereby controlling the workpiece conveying speed and matching the workpiece's dwell time in the polishing area with the polishing requirements. At the same time, the equipment is equipped with a dedicated switching power supply. The power module has wide voltage input, overvoltage, overcurrent, and short circuit protection functions, providing a stable DC or AC power supply for the other electrical components of the device and ensuring the reliable operation of all parts of the equipment.

[0023] An intermediate frame 24 is bolted to the upper end face of the bracket 21. The intermediate frame 24 is a one-piece cast structure with good structural strength. An electric push rod 25 is bolted to the middle of the upper end face of the intermediate frame 24. The electric push rod 25 is a linear actuator. Its push rod part is bolted to the intermediate frame 26. The electric push rod 25 is electrically connected to the PLC controller. The controller can send extension and retraction control signals to it to control the extension and retraction stroke of the push rod, thereby adjusting the spacing between the guide rollers. This spacing adjustment function allows the equipment to adapt to cylindrical workpieces of various diameters and achieve compatible processing of workpieces of various specifications.

[0024] A middle block 27 is bolted to the lower end of the middle frame 26. The middle block 27 enables the thrust of the electric push rod 25 to be evenly transmitted to the guide rollers on both sides. Limiting holes 29 adapted to the middle block 27 are opened on both sides of the bracket 21. The limiting hole 29 is a long strip through groove. Its length direction is consistent with the extension and retraction direction of the electric push rod 25, which restricts the movement trajectory of the middle block 27 and ensures that the guide roller can only move up and down in the vertical direction, thereby ensuring the accuracy of guiding the workpiece. A guide roller 28 is rotatably connected to the middle block 27 through a bearing. The roller surface of the guide roller 28 has good wear resistance and anti-slip properties. It cooperates with the main guide roller 23 to form a clamping and conveying mechanism for the workpiece, so that the workpiece keeps the axis stable during the conveying process.

[0025] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a polishing assembly 3 is installed on the desktop 11. The polishing assembly 3 includes a fixed base 31 that is bolted to the desktop 11. The fixed base 31 is a welded box structure. A drive motor 32 is bolted to one end of the fixed base 31. The drive motor 32 is a stepper motor with position control capability. Its output end passes through the fixed base 31 and is mounted with a bidirectional lead screw 33 through a coupling. It can drive the bidirectional lead screw 33 to achieve forward and reverse rotation and angle rotation. A slider 34 is threadedly connected to the body of the bidirectional lead screw 33.

[0026] The drive motor 32 is electrically connected to the PLC controller. The controller can send control pulses to the drive motor 32 according to the workpiece diameter parameters to control the rotation angle of the bidirectional lead screw 33, thereby driving the slider 34 to move to the preset position. The bottom of the slider 34 is provided with a guide boss that matches the guide cavity of the fixed seat 31, ensuring that the slider 34 moves smoothly along the length direction of the fixed seat 31 under the drive of the bidirectional lead screw 33 without jamming, thereby realizing the adjustment of the relative position between the polishing part and the workpiece.

[0027] An adapter 35 is bolted onto the slider 34. The adapter 35 is a rectangular plate structure. A polishing motor 36 is bolted onto the upper surface of the adapter 35. The polishing motor 36 is a high-speed variable frequency motor with a wide speed adjustment range. A rotating shaft 361 is coaxially mounted on its output end. The polishing motor 36 is electrically connected to a PLC controller. The controller can adjust the output speed of the polishing motor 36 according to the workpiece material and polishing requirements to achieve the best polishing and cleaning effect on the polished part.

[0028] A protective shell 37 is bolted to one side of the adapter 35. The protective shell 37 is a semi-enclosed shell that protects the polishing area. A polishing disc 38 is coaxially mounted on the rotating shaft 361 and located inside the protective shell 37. The polishing disc 38 is made of polishing material, and its surface texture can effectively remove impurities such as oil, metal shavings, and dust from the workpiece surface, while minimizing excessive wear on the workpiece body. One end of the rotating shaft 361 passes through the protective shell 37 and is coaxially mounted with a cleaning disc 39. The surface of the cleaning disc 39 is provided with cleaning bristles (not shown in the figure). When the rotating shaft 361 rotates, it can pre-clean the workpiece, reduce the content of dust and debris on the workpiece surface, and improve the cleaning effect of the workpiece.

[0029] like Figure 7 and Figure 8 As shown, a dust collection assembly 4 is installed on the desktop 11. The dust collection assembly 4 includes a lower dust cover 41 installed on the desktop 11. The lower dust cover 41 is a shell structure with an opening at the bottom. It is tightly connected to the dust collection part of the desktop 11 by bolts to form a dust collection channel at the bottom. An upper dust cover 411 is installed on the lower dust cover 41 by bolts. The upper dust cover 411 and the lower dust cover 41 cooperate to form a relatively closed polishing and dust removal space. The cleaning disc 39 is located inside the lower dust cover 41 and the upper dust cover 411, so that when the cleaning disc 39 rotates to clean, some of the dust and debris generated is confined inside the dust cover, reducing the diffusion to the outside of the equipment.

[0030] A dust collection hole 42, corresponding to the axis of the lower dust cover 41, is provided on the desktop 11. The dust collection hole 42 is a rectangular through hole, providing a smooth falling channel for dust and debris, allowing them to quickly enter the waste collection section below. An assembly box 43, corresponding to the axis of the dust collection hole 42, is bolted to the lower end face of the desktop 11. The assembly box 43 is a rectangular box structure, providing installation and housing space for the waste collection section, ensuring that the inlet of the waste collection section corresponds to the axis of the dust collection hole 42, allowing dust and debris to fall into the waste collection section. A waste collection box 44 is slidably installed inside the assembly box 43. The waste collection box 44 adopts a drawer-type structure and can slide smoothly along the guide rail of the assembly box 43, which is convenient for disassembly and cleaning. The lower end of the waste collection box 44 is connected to the lower end of the assembly box 43 by bolts. This connection method not only ensures the positional stability of the waste collection box 44 during operation, but also facilitates quick disassembly during cleaning, improving the maintenance convenience of the equipment. A filter screen 45 is installed inside the waste collection box 44 by bolts. The filter screen 45 is used to filter and intercept the inhaled dust and debris.

[0031] A dust extraction fan 46 is bolted to the lower end of the desktop 11. The dust extraction fan 46 is a centrifugal fan, characterized by high suction power and low noise. It is electrically connected to a PLC controller, which can adjust the airflow of the dust extraction fan 46 in real time according to the polishing conditions, ensuring effective collection of dust and debris under various polishing intensities. The air intake of the dust extraction fan 46 is connected to a vent pipe 47 via a flange. The vent pipe 47 is a flexible pipe with good bending performance, facilitating the layout and installation of the equipment. One end of the vent pipe 47 is connected to the waste collection box 44 via a flange. The flange connection ensures the airtight connection between the vent pipe 47 and the waste collection box 44, allowing the negative pressure generated by the dust extraction fan 46 to fully act on the waste collection box 44, efficiently sucking dust and debris into the waste collection box 44, preventing air leakage during the dust extraction process, and ensuring the stability of the dust extraction effect.

[0032] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
