Description

TECHNICAL FIELD

[0001] The utility model relates to a welding mechanism for plastic plate welding equipment belongs to plastic plate welding technical field. BACKGROUND

[0002] The welding mechanism for plastic plate welding equipment is a mechanical device specially designed for connecting or splicing plastic plates, and is widely used in the field of processing and manufacturing of plastic products. The welding mechanism melts the connecting part of the plastic plate through hot melting, ultrasonic wave, hot air or other heating methods, and then applies a certain pressure to make the molten part fuse and form a firm joint after cooling.

[0003] The surfaces of the two plates to be welded are adhered by hot melting welding, and the welding surfaces of the two plates are heated by the heating plate (electric heating device) to a certain extent. Remove the heating plate, quickly adhere the surfaces of the two plates and apply pressure, so that the molten part cools to form a firm weld. Under certain pressure, the weld cools and solidifies to form a bond.

[0004] Since the existing hot melting equipment only heats the surface of the plate, the heated welding surface during the welding process is only the adhered surface layer, resulting in limited melting depth and limited bonding area to the surface. Since the welding strength mainly depends on the bonding force of the molten layer, insufficient depth causes uneven stress distribution inside the weld, which cannot form a stable overall structure. Especially when processing long plates, the plates are long and are easily affected by uneven heating, unbalanced pressure distribution, self-weight deformation and other factors during operation, further weakening the welding effect, and ultimately leading to insufficient strength of the weld under tensile, shear and other stress conditions, which is difficult to meet the actual application requirements.

[0005] Therefore, a welding mechanism for plastic plate welding equipment is designed, which can improve the welding strength, especially when processing long plates, and can perform deep welding between two plates to form a high-strength plate. INVENTION CONTENTS

Due to the precise control of the welding process, the welding mechanism can be applied to plastic plates of different materials and thicknesses, and has wider applicability.

[0074] The first working area is the farthest end from the limit displacement of the upward movement of the welding strip 1, and the second working area is the height of the lower surface of the main plate 2 and the auxiliary plate 3.

[0075] It also includes a first positioning mechanism for placing the main plate 2, the first positioning mechanism includes a moving table 5 for placing the main plate 2, the first pushing assembly is installed on the upper side of the moving table 5, the first pushing assembly includes a first telescopic cylinder 61 arranged on one side of the main plate 2, and a first air pump 62 driving the first telescopic cylinder 61, the bottom of the first air pump 62 is fixedly installed on the moving table 5;

The second telescopic cylinder 81 is installed on the side of the side stop portion 722 facing the sub-plate 3, and the second air pump 82 is installed on the side of the side stop portion 722 away from the sub-plate 3.

[0082] By placing the main plate 2 and the sub-plate 3 on the moving table 5 and the fixed table 7 respectively, the two table surfaces can realize accurate positioning of the plates, ensuring the accurate position of the plates during welding.

[0083] The first telescopic cylinder 61 and the second telescopic cylinder 81 can respectively push the main plate 2 and the sub-plate 3, ensuring that they tightly adhere to the welding strip 1 during heating and welding, and reducing positional deviation.

[0084] During heating, the first telescopic cylinder 61 and the second telescopic cylinder 81 are respectively controlled by the first air pump 62 and the second air pump 82 to push the main plate 2 and the sub-plate 3 to tightly adhere to one side of the welding strip 1, ensuring uniform heating.

[0086] In the first work area, through the precise control of the first pushing assembly and the second pushing assembly, the hot melting area and the raised block can be formed on the main plate 2 and the auxiliary plate 3. This structural design can increase the contact area and bonding force of the welding surface, making the welding seam more firm. Through step-by-step operation, it is ensured that each welding surface can be fully melted and form a hot melting area and a raised block, thereby improving the overall welding strength.

[0087] The welding strip 1 comprises a fixed frame and a first soldering piece 13 installed on the left side of the fixed frame. The raised part 11 is vertically arranged and transversely arranged on the outer side of the first soldering piece 13.

[0088] The welding strip 1 further comprises a second soldering piece 14 installed on the right side of the fixed frame. The high-heat part 12 is vertically arranged and transversely arranged on the outer side of the first soldering piece 13.

[0089] The raised part 11 is a triangular pyramid structure, wherein the lower end width of the triangular pyramid is greater than the upper end width.

[0090] The high-heat part 12 is a triangular pyramid piece, wherein the lower end width of the triangular pyramid piece is greater than the upper end width.

[0091] The welding strip 1 further comprises a third soldering piece 15 installed above the fixed frame. The top of the third soldering piece 15 is flat.

[0092] Since the raised part 11 contacts the main plate 2 during heating, a hot melting area is formed on the side of the main plate 2 through thermal melting. This design can increase the shape complexity of the welding contact surface, thereby improving the welding strength.

[0093] The high-heat part 12 contacts the auxiliary plate 3 during heating, and a raised block is formed on the side of the auxiliary plate 3 through thermal melting. Similarly, this design can increase the shape complexity of the welding contact surface, thereby improving the welding strength.

[0094] Advantages of using the second pushing block and the second pushing assembly:

[0095] Double pushing and pressing, through the control of the control module 4 on the first pushing assembly and the second pushing assembly, the main plate 2 and the auxiliary plate 3 are respectively pushed and pressed on both sides of the welding strip 1. This double pressing design can ensure that the position of the plate during welding is more stable, reducing the welding error caused by the movement of the plate.

[0096] The transverse movement of the second pushing block can accurately control the position of the auxiliary plate 3, ensuring that it is aligned with the main plate 2, further improving the welding precision.

[0097] Not only increase the complexity of the contact surface, the design of the protruding part 11 and the high heat part 12 makes the shape of the welding contact surface more complex, increases the welding area and the contact point, thereby significantly improving the strength of the welding.

[0098] And can realize stable pressing, the design of double pushing block can ensure that the main plate material 2 and the vice plate material 3 are more stable on both sides of the welding strip 1, reduce the problem of welding area reduction and welding point misplacement caused by moving of the plate material in the welding process.

[0101] The welding strip 1 also includes a second welding sheet 14 installed on the right side of the fixed frame, the high heat part 12 is vertically arranged and transversely arranged on the outer side of the first welding sheet 13.

[0102] The protruding part 11 is a triangular pyramid structure, wherein the lower end width of the triangular pyramid is greater than the upper end width.

[0103] The high heat part 12 is a triangular pyramid sheet, wherein the lower end width of the triangular pyramid sheet is greater than the upper end width.

[0104] In order to facilitate the welding strip 1 in the process of moving down, the triangular pyramid structure can better penetrate into the material of the main plate material 2 during heating, forming a deeper fusion, and enhancing the welding contact point.

[0105] Because in the process of cooling the first welding sheet 13 and the second welding sheet 14 to the main plate material 2 and the vice plate material 3, the side edge will have molten plastic residue, which needs to be removed after welding is completed, and it takes a lot of time to remove the residue on both sides, therefore the welding strip 1 also includes a third welding sheet 15 installed on the fixed frame, and the top of the third welding sheet 15 is flat.

[0106] By the help of the third welding sheet 15, the lower surface of the main plate material 2 and the vice plate material 3 is fully adhered, which can spread the lower surface of the main plate material 2 and the vice plate material 3, and fully fill the weld of the lower surface of the main plate material 2 and the vice plate material 3, so as to present a seamless state, thereby forming a single surface.

[0107] The first soldering piece 13, the second soldering piece 14 and the third soldering piece 15 are made of copper, and the high-heat part 12 can be made of a material having better heat conduction performance than copper, such as a heat conduction compliant material or a metal matrix composite material.
