Description

Technical Field

[0001] This utility model provides a heating structure, and particularly relates to a heating structure for a device for curing anti-rust coating on the surface of a frame saw blade. Background Technology

[0002] During the production of frame saw blades, the surface needs to be coated with anti-rust paint. The heating structure of the anti-rust paint curing device is used to provide a suitable temperature environment for the paint to cure quickly and evenly. At the same time, in some scenarios, it is also necessary to assist in the flattening of the saw blade to ensure the anti-rust performance, service life, appearance and performance of the saw blade.

[0003] Existing heating structures for curing anti-rust coatings on frame saw blades mostly employ fixed heating components, enabling curing in only a single location. Even structures with adjustment functions often only involve unidirectional (e.g., horizontal or vertical) position adjustment and lack a movable adjustment design for the base. This structure makes it difficult to flexibly adjust the position of the heating components according to different saw blade sizes and coating distributions. It cannot accurately adapt to the curing needs of different areas of the saw blade, resulting in uneven drying effects. It also makes it difficult to achieve saw blade flatness during the curing process. Therefore, it is poorly suited for scenarios requiring multi-dimensional position adjustments to ensure curing quality and flatness. Utility Model Content

[0004] In order to solve the above problems, this application provides a heating structure for a frame saw blade surface anti-rust coating curing device, which solves the problem that the existing structure is insufficient in multi-dimensional adjustment and cannot achieve uniform drying and effective leveling of the saw blade anti-rust coating.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a heating structure for a rust-preventive coating curing device for frame saw blades, comprising: The base is a frame structure with an opening at the top; A lateral adjustment assembly is disposed above the base. The lateral adjustment assembly includes a lateral guide rail extending horizontally and a lateral moving seat that slides with the lateral guide rail. The lateral guide rail is mounted on the upper part of one end of the base through symmetrically distributed support plates. A longitudinal adjustment assembly is movably mounted on the transverse moving seat via a connecting plate. The longitudinal adjustment assembly includes a longitudinal guide rail extending in the vertical direction and a longitudinal moving seat that slides with the longitudinal guide rail. A heating component mounting bracket, which is a box structure with an opening on one side and is fixed on the longitudinal movable seat, is used to mount the heating component; A drive assembly, the drive assembly including a lateral drive member for driving the lateral moving seat to move along the lateral guide rail, and a longitudinal drive member for driving the longitudinal moving seat to move along the longitudinal guide rail.

[0006] Preferably, the base is a frame made of multiple profiles spliced ​​together, and the upper part of both sides of the base has mounting surfaces for mounting the transverse guide rails. There are two transverse guide rails, which are installed in parallel and spaced apart between the support plate. The drive assembly also includes a bottom guide rail located inside the base and connected to the mounting surface. A bottom drive component is provided on one side of the bottom guide rail. The bottom guide rail is distributed along the length direction of the base and the sliding direction of the mounting surface. The bottom drive component is a lead screw motor used to drive the mounting surface and the lateral adjustment assembly to move.

[0007] Preferably, the transverse moving seat includes a transverse connecting frame, the two ends of which are slidably connected to the two transverse guide rails via sliders, and the transverse connecting frame is provided with a mounting seat for mounting the longitudinal guide rail; the mounting seat and the connecting plate are fixedly connected by a bolt structure.

[0019] like Figure 1 and Figure 2 As shown, the heating structure of a frame saw blade surface anti-rust coating curing device includes a base 1, which is a frame structure with an open top, spliced ​​together from multiple profiles. The base 1 has bottom guide rails 11 distributed along its own length direction inside. A screw motor as a bottom driving component is provided on one side of the bottom guide rail 11 to drive the mounting surface 12 and the lateral adjustment component 2 to move. The upper parts of both sides of the base 1 have mounting surfaces 12. The lateral adjustment component 2 is located above the base 1 and includes two parallel and spaced lateral guide rails 21 that extend horizontally and are mounted on the upper part of one end of the base 1 through symmetrically distributed support plates. The lateral moving seat 22 is slidably engaged with the lateral guide rails 21. The lateral moving seat 22 includes a lateral connecting frame. The two ends of the lateral connecting frame are slidably connected to the two lateral guide rails 21 through sliders. The mounting seat on the lateral connecting frame is fixed to the connecting plate 31 by bolts.

[0020] In this embodiment, the connecting plate 31 of the longitudinal adjustment component 3 is made of Q235 steel plate with a thickness of 8mm. The contact surface between the plate and the mounting base of the transverse moving seat 22 is milled flat and can be detachably fixed by 4 sets of M10 hexagon socket bolts. Spring washers are added at the bolt connection to prevent loosening. The longitudinal guide rail 32 is a linear guide rail of model SBR20. The parallelism error of the two guide rails is controlled within 0.1mm / m. It is fixed in the guide rail mounting groove of the connecting plate 31 by countersunk bolts. The longitudinal moving seat 33 is made of high-strength aluminum alloy integral die casting. The slider that cooperates with the longitudinal guide rail 32 is a ball slider with a dust cover. The slider and the moving seat are rigidly connected by T bolts. The transverse drive component of drive assembly 4 uses a 400W servo screw motor with a 10mm lead ball screw. Both ends of the screw are fixed to the bearing seats at the ends of the transverse guide rail 21 via angular contact ball bearings. The screw nut and the transverse connecting frame are connected by a key and reinforced by spot welding. The longitudinal drive component uses a 300W servo screw motor with a 5mm lead ball screw. The bottom of the screw bears the axial force via a thrust ball bearing, and the top is equipped with a limit stop to prevent the longitudinal moving seat 33 from overtraveling. The heating component mounting bracket 5 is made of 1.5mm cold-rolled steel plate, bent into shape. The box length is adapted to the standard width of the frame saw blade (approximately 300-500mm). The mounting holes on the front side plate are φ12mm oblong holes with a hole spacing of 50mm to facilitate the adjustment of the heating component position. Three reinforcing ribs are welded to the inside of the mounting bracket to improve structural rigidity. The rear side plate and the longitudinal moving seat 33 are double-fixed by welding and bolts to ensure no relative shaking during heating. The base 1 is made of 40×40mm square steel tubing with a wall thickness of 3mm. After being spliced ​​by carbon dioxide gas shielded welding, the entire structure is treated with rust removal and painting. The bottom guide rail 11 is a linear guide rail of model SBR25, which slides in conjunction with the slider at the bottom of the mounting surface 12. The lead screw motor of the bottom drive component is arranged parallel to the bottom guide rail 11. Its output end is connected to the lead screw through a coupling. The lead screw nut is rigidly fixed to the connecting seat at the bottom of the mounting surface 12. In addition, 10mm thick rubber anti-slip pads are installed at the four corners of the bottom of the base 1 to prevent displacement during operation. Meanwhile, the device is also equipped with a PLC control system. The laser distance sensor installed on the longitudinal moving seat 33 detects the distance between the heating component mounting bracket 5 and the saw blade in real time. After the sensor signal is transmitted to the PLC, it controls the start, stop and speed of each drive component to achieve precise linkage of horizontal, vertical and bottom three-dimensional adjustment with an adjustment accuracy of up to 0.05mm. The outer sides of the horizontal guide rail 21, the longitudinal guide rail 32 and the bottom guide rail 11 are all fitted with accordion-style dust covers to prevent dust from entering the gap between the guide rails and affecting the sliding accuracy.

[0021] like Figure 3 , 4As shown in Figure 5, the longitudinal adjustment assembly 3 is movably mounted on the mounting base of the transverse moving seat 22 via the connecting plate 31. It includes two parallel longitudinal guide rails 32 extending vertically and spaced apart, and a longitudinal moving seat 32 that slides with the longitudinal guide rails 32. The drive assembly 4 also includes a transversely arranged lead screw motor as a transverse drive component. The lead screw of the lead screw motor is connected to the transverse connecting frame via a lead screw nut to drive the transverse connecting frame to slide along the transverse guide rail 21. It also includes a vertically arranged lead screw motor as a longitudinal drive component. The lead screw of the lead screw motor is connected to the longitudinal moving seat 33 via a lead screw nut (the lead screw is distributed parallel between the longitudinal guide rails 32) to drive the longitudinal moving seat 32 to slide along the longitudinal guide rail 32. In addition, there is a heating component mounting bracket 5, which is a box structure with one side opening. It has a front side plate, a rear side plate, and two side plates connecting the front side plate and the rear side plate. The front side plate has multiple mounting holes for mounting heating components, and the heating component mounting bracket 5 is fixed on the longitudinal moving seat 33.

[0022] In this embodiment, the connecting holes of the connecting plate 31 and the mounting base of the transverse moving seat 22 are all machined by reaming, and high-precision positioning is achieved with transition bolts. A ring-shaped reinforcing boss is added around the bolt holes to improve the deformation resistance of the connection. The bottom of the longitudinal guide rail 32 is fixed to the connecting plate 31 via an L-shaped positioning plate. A 0.1mm thick copper foil gasket is pasted on the contact surface between the positioning plate and the guide rail for fine-tuning the verticality of the guide rail. A detachable limit block is installed on the top of the guide rail, with a polyurethane buffer pad pasted on the inner side of the limit block to prevent impact damage to the longitudinal moving seat 33. The lead screw motor of the transverse drive component is suspended on the crossbeam between the transverse guide rails 21 via a motor mount. The motor mount and the crossbeam are connected by a T-slot, allowing for fine-tuning of the motor position along the transverse direction to ensure the lead screw is parallel to the guide rail. The lead screw motor of the longitudinal drive component is fixed to the motor mounting plate on the top of the connecting plate 31. A wedge-shaped adjusting block is provided between the mounting plate and the connecting plate 31. By turning the set screw on the adjusting block, the parallelism deviation between the motor axis and the longitudinal guide rail 32 can be corrected. The front and side plates of the heating component mounting bracket 5 are welded together with folded edges, and the weld seams are ground smooth. The mounting holes on the front plate are all countersunk to facilitate the sinking of the bolt heads of the heating components and prevent them from protruding and scratching the saw blade. The rear plate of the mounting bracket has a positioning pin on the contact surface with the longitudinal moving seat 33, which is fastened by two sets of M8 high-strength bolts. The bolt shanks are covered with metal sleeves to prevent the bolts from bending when the mounting bracket is under stress. In addition, the connection surface between the longitudinal moving seat 33 and the slider is ground, and the flatness error is controlled within 0.03mm. The lead screw nut of the transverse drive component is equipped with a limit switch stop block on the outside, which works with the limit switches installed at both ends of the transverse guide rail 21 to realize transverse movement overtravel protection. The heating component mounting bracket 5 has a strip-shaped mounting strip welded inside the box. The mounting strip has multiple sets of threaded holes to accommodate the fixing requirements of heating components of different sizes. The bottom of the side plates of the mounting bracket has guide slopes to facilitate alignment with the edge of the frame saw blade.

[0023] In use, this device can be operated as follows, depending on the specific implementation status: I. Operational dynamics of components under light drying conditions The bottom drive unit inside the base 1 is activated, driving the mounting surface 12 to move along the bottom guide rail 11 along the length of the base 1 to the area where the frame saw blade is to be dried; the lateral drive unit of the lateral adjustment component 2 operates, driving the lateral moving seat 22 to slide horizontally along the lateral guide rail 21, adjusting the lateral alignment position of the heating component mounting bracket 5; the longitudinal drive unit of the longitudinal adjustment component 3 drives the longitudinal moving seat 33 to move upward along the longitudinal guide rail 32, so that the heating component mounting bracket 5 maintains a relatively large distance of 10-15cm from the frame saw blade; then the heating component on the heating component mounting bracket 5 is activated, using low power output to achieve light drying of the anti-rust coating on the saw blade. During this process, all guide rails and drive components remain locked in position, with no additional displacement.

[0024] II. Component Operation Dynamics under Deep Drying Condition The bottom drive component finely adjusts the position of the mounting surface 12 along the bottom guide rail 11 according to the saw blade drying requirements, ensuring that the lateral adjustment component 2 is aligned with the local area of ​​the saw blade that needs to be deeply dried; the lateral drive component drives the lateral moving seat 22 to slide back and forth along the lateral guide rail 21 in a small range, expanding the lateral drying coverage area; the longitudinal drive component drives the longitudinal moving seat 33 to move downward along the longitudinal guide rail 32, reducing the distance between the heating component mounting bracket 5 and the saw blade to 3-5cm; the heating component switches to high power output, while the lateral moving seat 22 maintains slow lateral movement, achieving uniform and deep drying of the coating on the saw blade surface, and the base 1 and the bottom guide rail 11 maintain a stable support state.

[0025] III. Component Operation Dynamics During Flattening (Combined with Drying) The bottom drive component drives the mounting surface 12 to move at a constant speed along the bottom guide rail 11, providing a moving base for flattening the entire length of the saw blade; the transverse drive component adjusts the position of the transverse moving seat 22 along the transverse guide rail 21, so that the side plate of the heating component mounting bracket 5 is completely aligned with the width direction of the saw blade; the longitudinal drive component of the longitudinal adjustment component 3 continuously outputs driving force, pushing the longitudinal moving seat 33 to move downward along the longitudinal guide rail 32 until the front side plate of the heating component mounting bracket 5 or the installed auxiliary pressure strip contacts the surface of the saw blade and generates a preset pressure; the heating component starts at medium power, and together with the bottom guide rail 11, drives the whole to move along the length direction of the saw blade, achieving the saw blade flattening operation through "heating softening + pressure shaping", and the transverse moving seat 22 is finely adjusted in real time according to the transverse deviation of the saw blade to ensure flattening accuracy.

[0026] During installation, the base must first be leveled using a spirit level, then fixed to the concrete foundation with expansion bolts. When installing the bottom guide rail, a dial indicator is used to check its parallelism with the length of the base. After adjustment, it is tightened with countersunk bolts. The device needs to be used in conjunction with an inclined feeding rack and a receiving rack with buffer springs. The feeding rack transports the frame saw blades one by one to the conveyor roller group, while the receiving rack receives the cured saw blades. Before operation, the operator needs to start the system using the key switch on the distribution box, and call up the preset saw blade parameter formula (including heating temperature, speed adjustment, etc.) on the PLC touch screen. Then, the photoelectric sensor is activated to locate the saw blade position. After the positioning signal is transmitted to the PLC, the PLC automatically controls the bottom drive to move the lateral adjustment component to the corresponding position. During operation, the rotational speed of the conveyor rollers is adjusted by a frequency converter to ensure it matches the heating and curing speed. When the temperature sensor detects a deviation from the set value, the PLC immediately adjusts the power output of the heating components. If the saw blade deviates, the photoelectric sensor triggers a signal, and the PLC immediately controls the emergency stop button to operate, simultaneously stopping the conveyor rollers and all drive components. The system restarts after manual adjustment of the saw blade position. For routine maintenance, the guide rail surface should be cleaned regularly with a brush to remove dust, and lithium-based grease should be applied monthly. The activated carbon in the adsorption box should be replaced quarterly. When replacing the activated carbon, the axial fan power must be turned off first, and then the adsorption box end cover should be removed for replacement. During equipment overhaul, the insulation of each motor winding should be tested with a multimeter, and the grounding resistance should be measured with a megohmmeter to ensure it does not exceed 4 ohms, in accordance with electrical safety regulations.

[0027] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the claims.
