Description

Technical Field

[0001] This utility model specifically relates to the field of high-frequency welding machine technology, and more specifically to a precision dual-station rotary high-frequency welding machine for multi-angle welding. Background Technology

[0002] A high-frequency machine is a device that uses a high-frequency electromagnetic field to process materials. The high-frequency machine mainly uses a high-frequency electron tube self-excited oscillator to generate a high-frequency electromagnetic field. When the object to be processed is placed between the upper and lower electrodes of the high-frequency electromagnetic field, its internal molecules are excited and move at high speed. The molecules rub against each other to generate heat, which in turn causes the material itself to generate heat and flow and penetrate each other. Finally, under the pressure of the mold, the purpose of welding (fusion), embossing or melting is achieved.

[0003] High-frequency welding machines are widely used in blister packaging, such as heat sealing and trimming of double blister packs, heat sealing and trimming of blister packs and cardboard, etc. They are also suitable for welding and sealing various plastic films and sheets, such as the production of packaging bags and boxes made of PVC, PET, PP and other materials.

[0004] However, in practice, it has been noted that when packaging materials such as plastic toys, the toys need to be placed in the plastic shell, and then the edges are welded by heating and extrusion of the mold. The welded parts of some toys are set at an angle, which requires the welding mold to be tilted and adjusted. This takes some time and affects the processing efficiency. Utility Model Content

Each inclined baffle is fixedly connected to a dovetail-shaped slider corresponding to the limit groove at its bottom.

[0013] As a further technical solution of this utility model, the dovetail-shaped slider is inserted into the inner side of the limiting slide groove, and the dovetail-shaped slider slides in slidable engagement with the inner side of the limiting slide groove.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figure 1-7 This utility model embodiment provides a precision dual-station rotary high-frequency welding machine for multi-angle welding, including a frame housing 1, a first mounting bracket 2 fixedly connected to one end of the upper part of the frame housing 1, a lifting component 5 fixedly connected to the end of the first mounting bracket 2, and a welding component 4 installed below the lifting component 5.

[0035] The lifting assembly 5 includes a support plate 51 fixedly connected to the first mounting bracket 2, and a compression cylinder 52 is fixedly connected to the support plate 51. The end of the compression cylinder 52 passes through the support plate 51 and is fixedly connected to an upper connecting plate 54.

[0036] The welding assembly 4 includes a fixed ball head 45 fixedly connected to the lower part of the upper connecting plate 54, and a ball head seat 44 is snapped into the bottom of the fixed ball head 45. A heating template 41 and a connecting pressure plate 43 arranged in parallel are fixedly connected below the ball head seat 44. Heat insulation pads 42 are fixedly connected between the heating template 41 and the connecting pressure plate 43 in a rectangular array.

[0037] Furthermore, the upper connecting plate 54 is symmetrically fixedly connected with limiting slide rods 53, and the limiting slide rods 53 are respectively located on both sides of the extrusion cylinder 52, and the ends of the limiting slide rods 53 extend through the supporting horizontal plate 51 to the top of the supporting horizontal plate 51.

[0038] By adopting the above technical solution, the connecting pressure plate 43 is installed below the upper connecting plate 54 through the ball head seat 44 and the fixed ball head 45. Through the movable connection between the ball head seat 44 and the fixed ball head 45, the heating template 41 can be tilted below the lifting assembly 5, thereby tilting the material for welding, increasing the processing function of the material. In addition, a heat insulation pad 42 is fixedly connected between the heating template 41 and the connecting pressure plate 43, which can play a role in heat insulation and improve the safety during use.

[0039] Furthermore, a bottom driver 8 is movably connected to one end of the frame housing 1 away from the first mounting bracket 2, and a dual-station turntable 7 is fixedly connected above the bottom driver 8. The dual-station turntable 7 is located above the frame housing 1, and one end of the dual-station turntable 7 is located below the heating template 41.

[0040] Furthermore, the dual-station turntable 7 includes a worktable 71, on which limit grooves 72 are symmetrically provided, and inclined baffles 73 are symmetrically provided above the worktable 71. Each inclined baffle 73 is fixedly connected to a dovetail-shaped slider 74 corresponding to the limit groove 72 at its bottom.

[0041] More specifically, the dovetail-shaped slider 74 is inserted into the inner side of the limiting slide groove 72, and the dovetail-shaped slider 74 slides in cooperation with the inner side of the limiting slide groove 72. Each of the dovetail-shaped sliders 74 has threaded holes at both ends, and a locking screw 75 is threaded into the threaded hole at either end.

[0042] Furthermore, both ends of the bottom of the workbench 71 are integrally provided with positioning protrusions 76, and the lower part of the workbench 71 near the first mounting bracket 2 is provided with a positioning plate 6 fixedly connected to the machine frame housing 1, and the positioning plate 6 is provided with a corresponding groove corresponding to the positioning protrusions 76, and the positioning protrusions 76 and the corresponding grooves are inserted and engaged.

[0043] By adopting the above technical solution, the locking screw 75 is loosened, and the position of the inclined baffle 73 above the worktable 71 is adjusted through the sliding cooperation between the dovetail slider 74 and the limiting slide groove 72. The inclined worktable 71 can tilt the material. With the adjustable welding component 4, welding can be performed on the inclined surface of the material or on the inclined material, thereby increasing the material processing function of the equipment.

[0044] Furthermore, the bottom driver 8 includes a second mounting bracket 81 fixedly connected to the frame housing 1, and a parallel movable connecting plate 82 is provided above the second mounting bracket 81, and a positioning sleeve 811 and a positioning rod 821 with sliding fit are respectively provided between the second mounting bracket 81 and the movable connecting plate 82.

[0045] The positioning rod 821 is fixedly connected to the second mounting bracket 81, and the positioning rod 821 is fixedly connected to the movable connecting plate 82.

[0046] More specifically, the two ends of the upper part of the movable connecting plate 82 are respectively fixedly connected to the gearbox 83 and the drive motor 84, and the ends of the drive motor 84 and the gearbox 83 are both interference-fitted with the connecting sprocket 86, and the outer side of the connecting sprocket 86 is connected with the transmission chain.

[0047] Furthermore, a lifting cylinder 85 is fixedly connected to the lower part of the second mounting bracket 81, and the upper part of the lifting cylinder 85 passes through the second mounting bracket 81 and is fixedly connected to the movable connecting plate 82.

[0048] The output rod of the gearbox 83 is fixedly connected to the middle position of the bottom of the worktable 71.

[0049] By adopting the above technical solution, the lifting cylinder 85 pushes the movable connecting plate 82 upward, thereby causing the gearbox 83 on the movable connecting plate 82 to push the worktable 71 upward, so that the positioning protrusion 76 under the worktable 71 separates from the positioning plate 6. After the two ends of the worktable 71 are swapped, the lifting cylinder 85 drives the movable connecting plate 82 downward until the positioning protrusion 76 under the worktable 71 is inserted into the corresponding groove on the positioning plate 6, thereby positioning the worktable 71 and preventing displacement during the welding process of plastic products.

[0050] Furthermore, the extrusion cylinder 52, drive motor 84, and lifting cylinder 85 are electrically connected to the control panel 3 via wires. A high-frequency electron tube self-excited oscillator is also installed at the bottom of the heating template 41. The high-frequency electron tube self-excited oscillator generates a high-frequency electromagnetic field, causing the material molecules below the heating template 41 to rub against each other and generate heat. This causes the material to generate heat and flow and penetrate each other, thus completing the welding (the above-mentioned high-frequency electron tube self-excited oscillator is a commonly used prior art in this field and is also well known to those skilled in the art, so it will not be described in detail here).

[0051] The working principle of this utility model is as follows: First, loosen the locking screw 75. Through the sliding cooperation between the dovetail slider 74 and the limiting groove 72, adjust the position of the inclined baffle 73 above the worktable 71. The material is clamped by the two symmetrically arranged inclined baffles 73, and the inclined worktable 71 allows the material to be placed at an angle. Then, the lifting cylinder 85 pushes the movable connecting plate 82 upwards, causing the gearbox 83 on the movable connecting plate 82 to push the worktable 71 upwards, separating the positioning protrusion 76 below the worktable 71 from the positioning plate 6. The drive motor 84, through chain transmission with the gearbox 83, causes the output shaft of the gearbox 83 to drive the worktable 71 to rotate horizontally. The material above the worktable 71 moves to below the welding assembly 4. Then, the lifting cylinder 85 drives the moving connecting plate 82 to move downward until the positioning protrusion 76 below the worktable 71 inserts into the corresponding groove on the positioning plate 6, thereby positioning the worktable 71 and preventing displacement during the welding of plastic products. Then, the squeezing cylinder 52 pushes the upper connecting plate 54 downward until the heating template 41 contacts the material surface. After contact, the high-frequency electron tube self-excited oscillator inside the heating template 41 generates a high-frequency electromagnetic field, thereby welding the materials together. The movable connection between the ball head seat 44 and the fixed ball head 45 allows the heating template 41 to adaptively adjust according to the tilt angle of the welding position, thereby improving efficiency.

[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0053] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
