Description

Technical Field

[0001] This utility model belongs to the field of welding machine technology, and more specifically, it relates to a high-temperature heat welding device with automatic feeding and discharging. Background Technology

[0002] When welding plastic products, high-frequency welding machines are generally used. The working principle of high-frequency welding machines is based on high-frequency dielectric heating technology. It uses an electronic self-excited oscillator to generate a high-frequency electric field, usually using the international standard industrial frequency of 27.12MHz. This high-frequency electric field is then applied to the electrodes. Under the action of the high-frequency electric field, the molecular structure of the plastic undergoes polarization, and the friction between molecules generates heat. Under pressure, this heat causes the plastic to reach a thermal melting state, thus achieving welding. Existing high-frequency welding machines are generally equipped with a slide table for automatic feeding and discharging. Workers place the plastic on the slide table, which then transports the plastic to the welding area. The welded plastic is then transported out by the slide table.

[0003] The existing application number, CN201810876231.7, discloses a fully automatic high-frequency welding machine, including a frame, at least one welding unit, a conveying device, and a programmable controller. The welding unit includes a vibrating drum, a welding worktable, a lifting device, a welding head and a welding blade connected to the lower end of the lifting device. The welding blade is connected to the high-frequency output end of the vibrating drum via a copper strip and a high-frequency output switch. The conveying device includes a conveyor motor, a first transmission shaft and a second transmission shaft that transmit power to the drive shaft of the conveyor motor via a synchronous belt, a first pneumatic device, a first driven shaft, a second driven shaft, a conveyor belt, and a material shaft. The first pneumatic device in the conveying device, driven by a slider and the synchronous belt, converts the rotation of the conveyor motor into linear motion, achieving automatic feeding and alignment, thus realizing automatic welding and cutting of the high-frequency welding machine. This invention provides a fully automatic high-frequency welding machine with high production efficiency, requiring no manual movement or alignment, and producing high-quality products.

[0004] Based on the above, when the plastic products are welded, the slide transports the welded plastic to the retrieval area, and workers usually remove the plastic manually. However, since the plastic products that have just been welded still retain a certain amount of heat, there is a risk of burns when workers pick them up, which poses a certain safety hazard. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an automatic feeding and discharging high-temperature hot-melt welding device. This solves the problem that, in existing systems, after the plastic products are welded, the slide transports the welded plastic to the retrieval area, where workers typically remove the plastic manually. However, since the freshly welded plastic products still retain some heat, workers are at risk of being burned when handling them, posing a certain safety hazard.

[0020] The right end of the protective transmission rope is fixedly connected to the outer circumference of the protective drive shaft, the protective transmission rope is wrapped around the outer circumference of the protective guide wheel, and the left end of the protective transmission rope is fixedly connected to the protective drive slider.

[0024] The third trigger is fixedly connected to the rear left side of the feeding slide, and the third trigger and the first trigger form a wedge structure.

[0025] Furthermore, the material feeding protection mechanism includes: a material feeding pad, a material feeding connecting spring, a material feeding limiting plate, a protective connecting spring, and a material feeding blocking plate;

[0026] The material feeding pad is slidably connected to the inside of the material feeding protective cover;

[0027] Two sets of feeding connecting springs are provided. The two sets of feeding connecting springs are fixedly connected to the inside of the feeding protective cover. The left end of both sets of feeding connecting springs is fixedly connected to the feeding pad.

[0028] The material feeding limiting plate is hinged to the upper left side of the inside of the material feeding protective cover;

[0029] The protective connecting spring is a right-angle spring structure, and the protective connecting spring is fixedly connected to the outer circumference of the rotating shaft of the unloading limit plate;

[0030] The material discharge shield is fixedly connected to the upper left side of the inside of the material discharge protective cover, and the material discharge shield is located on the left side of the material discharge limiting plate.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] This invention, through the setting of a protective drive mechanism, places the workpiece above the loading and carrying slide. The loading and carrying slide then moves to the right, bringing the workpiece into the welding area. After welding is completed, the loading and carrying slide continues to move to the right, causing the second trigger to move to the right. After the second trigger moves to the right of the first trigger, the loading and carrying slide moves to the left, causing the second trigger to move to the left, which in turn causes the first trigger to move to the left. The first trigger moves the protective drive slider to the left, pulling the protective transmission rope. Guided by the protective guide wheel, the protective transmission rope drives the protective drive shaft to rotate, energizing the protective reset spring. Simultaneously, when the first trigger moves to the left and contacts the third trigger, the protective drive slider resets under the action of the protective reset spring. This facilitates the workpiece unloading operation, avoids manual operation by workers, and reduces their labor intensity.

[0036] This invention, through the setting of the unloading protection mechanism, ensures that when the loading carrier slide moves to the right and brings the workpiece into the unloading protective cover, the unloading pad is squeezed to the right. At the same time, when the loading carrier slide moves to the left, the unloading limit plate, under the action of the unloading baffle, scrapes the workpiece onto the unloading pad. Simultaneously, the protective drive shaft rotates, driving the protective drive screw to rotate. The rotation of the protective drive screw drives the unloading drive slider forward, slowly pushing the workpiece onto the rectangular plate of the unloading protective cover. This ensures the slow unloading of the workpiece, provides cooling time for the welded workpiece, avoids burns to workers, and improves the safety of the entire welding machine.

[0044] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. Example 1:

[0045] As attached Figure 1 To be continued Figure 5 As shown:

[0046] This utility model provides a high-temperature hot-melt welding device with automatic feeding and discharging, including a welding machine base 1, a welding machine head 2, a feeding slide 3, a feeding bearing slide 4, a discharging protective cover 5, a protective drive shaft 6, and a protective drive mechanism.

[0047] The welding head 2 is welded above the welding machine base 1;

[0048] The feeding slide 3 is fixedly connected to the top of the welding machine base 1;

[0049] The feeding support slide 4 is slidably connected above the feeding slide 3;

[0050] The unloading protective cover 5 is fixedly connected to the upper right side of the loading slide 3, and the front end of the unloading protective cover 5 is provided with a rectangular plate structure;

[0051] The protective drive shaft 6 is rotatably connected to the rear end of the unloading protective cover 5;

[0052] The protective drive mechanism is located behind the feeding slide 3.

[0053] The protective drive mechanism includes: a protective reset spring 101, a protective drive slider 102, a protective guide wheel 103, a protective transmission rope 104, a first trigger 105, a second trigger 106, and a third trigger 107.

[0054] The protective reset spring 101 is a spiral spring structure, and the protective reset spring 101 is fixedly connected to the outer periphery of the protective drive shaft 6.

[0055] The protective drive slider 102 is slidably connected to the rear of the feeding slide block 3;

[0056] The protective guide wheel 103 is rotatably connected to the rear right side of the feeding slide 3;

[0057] The right end of the protective transmission rope 104 is fixedly connected to the outer periphery of the protective drive shaft 6, the protective transmission rope 104 is wrapped around the outer periphery of the protective guide wheel 103, and the left end of the protective transmission rope 104 is fixedly connected to the protective drive slider 102.

[0058] The first trigger 105 is slidably connected to the upper end of the inside of the protective drive slider 102, and a spring structure is provided at the lower end of the first trigger 105.

[0059] The second trigger 106 is fixedly connected to the bottom of the feeding support slide 4, and the second trigger 106 and the first trigger 105 form a wedge structure.

[0060] The third trigger 107 is fixedly connected to the rear left side of the feeding slide 3. The third trigger 107 and the first trigger 105 form a wedge structure.

[0061] In use, when welding a workpiece is required, the workpiece is placed above the loading support slide 4. The loading support slide 4 then moves to the right, bringing the workpiece into the welding area. After welding is complete, the loading support slide 4 continues to move to the right, causing the second trigger 106 to move to the right. After the second trigger 106 moves to the right side of the first trigger 105, the loading support slide 4 moves to the left, causing the second trigger 106 to move to the left, which in turn causes the first trigger 105 to move to the left. When component 105 moves to the left, it drives the protective drive slider 102 to move to the left. The protective drive slider 102 moves to the left and pulls the protective transmission rope 104. Under the guidance of the protective guide wheel 103, the protective transmission rope 104 drives the protective drive shaft 6 to rotate. The rotation of the protective drive shaft 6 charges the protective reset spring 101. At the same time, when the first trigger component 105 moves to the left and contacts the third trigger component 107, the protective drive slider 102 is reset under the action of the protective reset spring 101. This facilitates the unloading operation of the workpiece, avoids manual operation by the worker, and reduces the labor intensity of the worker. Example 2:

[0070] The unloading drive slider 507 is slidably connected to the upper part of the inside of the unloading protective cover 5, and the unloading drive slider 507 is threadedly connected to the protective drive screw 506.

[0071] During use, when the loading slide 4 moves to the right and brings the workpiece into the unloading protective cover 5, the unloading pad 501 is squeezed to the right. At the same time, when the loading slide 4 moves to the left, the unloading limit plate 503 scrapes the workpiece onto the unloading pad 501 under the action of the unloading baffle plate 505. At the same time, the protective drive shaft 6 rotates, driving the protective drive screw 506 to rotate. The rotation of the protective drive screw 506 drives the unloading drive slider 507 to move forward. The unloading drive slider 507 moves forward slowly, pushing the workpiece onto the rectangular plate of the unloading protective cover 5, ensuring the slow unloading of the workpiece and providing cooling time for the welded workpiece, thus preventing the workpiece from burning the worker. At the same time, the protective drive shaft 6 reverses, driving the unloading drive slider 507 to reset.
