Description

Technical Field

[0001] This utility model relates to the field of hot plate welding, and in particular to a servo oiling mechanism. Background Technology

[0002] The hot plate welding machine adopts a pull-out plate structure. It uses electric heating to transfer heat from the heating plate to the welding surfaces of the upper and lower plastic heating parts, melting their surfaces. The heating plate is then quickly withdrawn, allowing the heated surfaces of the two parts to fuse, solidify, and become a single unit. The entire machine is a frame structure, composed of three main plates: an upper template, a lower template, and a hot template, along with hot molds and upper and lower plastic cold molds. The operation is pneumatic, hydraulic, or motor-controlled, and is primarily suitable for welding plastic parts used in household appliances, automotive lights, and automotive containers.

[0003] Hot plate welding machines are characterized by their simple structure, convenient operation, and high production efficiency. After welding, they can achieve watertight and airtight connections, making them suitable for shrink-fitting heat-sensitive plastic parts of various shapes, sizes, and materials. It is a versatile, economical, practical, and highly efficient welding process for users.

[0004] In hot plate welding or thermoforming processes, workpieces tend to adhere to the hot plate surface under high temperatures, leading to decreased product quality and reduced production efficiency. Traditional oiling methods typically employ manual or simple mechanical devices, which suffer from the following problems: inaccurate oil volume control, resulting in uneven oil film and affecting product quality; excessive oil volume, which can generate fumes at high temperatures, polluting the working environment and harming operator health; and low automation, making it difficult to meet the demands of high-precision, high-efficiency production. Servo oiling can handle products with irregular surfaces, while pneumatic oiling is limited to flat surfaces and cannot address complex, uneven surfaces.

[0005] To address the problems existing in the background art, this utility model provides a servo oiling mechanism. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a servo oiling mechanism.

The welding machine includes an upper oiling mechanism fixing plate, an upper mold worktable, a hot mold motion plate, a hot mold motion plate moving slide rail, a lower mold worktable, a lower oiling mechanism fixing plate, and left and right hot mold motion plate fixing bases. A servo translation mechanism is fixed on the lower side of the upper oiling mechanism fixing plate and the upper side of the lower oiling mechanism fixing plate. A back plate is fixed on the rear end of the lower side of the upper oiling mechanism fixing plate and the rear end of the upper side of the lower oiling mechanism fixing plate. A servo lifting mechanism is provided on one side of both back plates. An oiling head is fixed at the end of the servo lifting mechanism.

[0009] Furthermore, the brush head below is equipped with an oil collection box.

[0010] Furthermore, a telescopic spring connects the servo lifting mechanism to the brush head.

[0011] Furthermore, the brush head is hemispherical, and a high-temperature resistant cloth is fixed to the surface of the brush head.

[0013] Furthermore, it also includes an oil-proof safety protection mechanism, which includes a baffle at the front of the servo translation mechanism and a chassis at the rear of the lower oil-proof safety protection mechanism.

[0014] The beneficial effects of this utility model are as follows: it can accurately control the amount of oil, coat evenly, prevent material sticking and produce no smoke. By uniformly coating the release agent, it can completely solve the problem of product sticking, improve the yield rate, reduce mechanical wear of the servo system, and extend the service life of the equipment.

[0018] The specific solutions and embodiments of this utility model will be further described with reference to the accompanying drawings.

[0019] As shown in the figure, a plastic hot melt welding anti-sticking mechanism is disclosed. The welding machine includes an upper oiling mechanism fixing plate 1, an upper mold worktable 2, a hot mold moving plate 3, a hot mold moving plate sliding rail 4, a lower mold worktable 5, a lower oiling mechanism fixing plate 6, and left and right hot mold moving plate fixing bases 7. The lower oiling mechanism fixing plate 6 is fixed to the base frame, and the left and right hot mold moving plate fixing bases 7 are fixed to the lower oiling mechanism fixing plate 6. The lower mold worktable 5 is provided on the left and right hot mold moving plates 3. Hot mold moving plates 3 are placed on the left and right hot mold moving plates 3, and left and right hot mold moving plate sliding rails 4 are provided on both sides. An upper frame is also fixed to the side of the base frame. The upper frame has the upper oiling mechanism fixing plate 1 on its upper part, and the upper mold worktable 2 is provided below the upper oiling mechanism fixing plate 1.

[0020] The lower side of the upper brushing mechanism fixing plate 1 and the upper side of the lower brushing mechanism fixing plate 6 are both equipped with servo translation mechanisms 8. The rear end of the lower side of the upper brushing mechanism fixing plate 1 and the rear end of the upper side of the lower brushing mechanism fixing plate 6 are both fixed with back plates. One side of each of the two back plates is equipped with a servo lifting mechanism 9, and the end of each servo lifting mechanism 9 is fixed with a brushing head 10.

[0021] It also includes an oil-proof safety protection mechanism 12, which includes a baffle at the front of the servo translation mechanism 8 and a chassis at the rear of the lower oil-proof safety protection mechanism.

[0022] Servo translation is an automatic control system that tracks input command signals to achieve precise position, speed, and power output. Mechanical transmission is an intermediate device that transmits motion and power generated by a power source to an actuator; it acts as a torque and speed converter, aiming to achieve a proper torque match between the power source and the load, and can adjust the output speed through mechanism changes. In mechatronics systems, the servo motor's servo speed-changing function largely replaces the traditional speed-changing mechanism in mechanical transmissions. Speed ​​changes are only used through a transmission device when the servo motor's speed range cannot meet system requirements.

[0023] The brush head 10 is hemispherical, and a high-temperature resistant cloth is fixed to its surface. The brush head 10 at the bottom is equipped with an oil collection box.

[0024] A telescopic spring 11 connects the servo lifting mechanism 9 and the brush head 10 to prevent excessive cylinder pressure and provides a certain degree of adjustability. Four telescopic springs 11 are located at the four corners of the end plate of the servo lifting mechanism 9, ensuring even and stable force distribution.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention.
