Description

Technical Field

[0001] The utility model relates to the technical field of air mattress processing equipment, in particular to a welding machine for inflating ports of air mattresses. Background Art

[0002] An air mattress needs to be inflated to be used. Therefore, an inflating port convenient for connecting with an air pump needs to be provided. The inflating port is generally a plastic connector matching with the air pump, and the inflating port is generally fixed on the plastic cloth on the side of the air mattress by means of welding.

[0003] In the prior art, the welding operation process for the inflating port is as follows: First, place the plastic cloth of the air mattress on the working table of the welding machine, manually adjust the position of the plastic cloth of the air mattress so that the corresponding opening of the plastic cloth of the air mattress is directly below the high-frequency welding die, then place the plastic connector of the inflating port into the corresponding opening of the plastic cloth of the air mattress, and finally control the pneumatic rod of the welding machine to descend so that the high-frequency welding die covers the plastic part of the inflating port for high-frequency welding.

[0004] In the above operation, the entire process requires manual assistance. It is difficult to ensure that the corresponding opening of the plastic cloth of the air mattress and the plastic connector are directly opposite to the high-frequency welding die. Not only is the error large, the labor intensity is high, but also the operation efficiency is low and the welding quality is poor, which urgently needs to be improved. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a welding machine for inflating ports of air mattresses, which can realize the rapid positioning of the opening of the plastic cloth and the plastic connector of the inflating port, and has high positioning accuracy, so that the operation efficiency is high, the manual labor intensity is small, the welding quality is good, and a condensation channel is embedded inside the high-frequency welding die, so that the high-frequency welding die can quickly cool the welding area after welding is completed, avoiding the situation that the welding area cracks due to untimely condensation, and further improving the welding effect of the plastic connector of the inflating port.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

[0007] A welding machine for inflating ports of air mattresses includes a working table, a high-frequency welding die is arranged on the working table, the high-frequency welding die is connected with a longitudinal driving cylinder above the working table, the longitudinal driving cylinder is fixed on the machine body, and a positioning mechanism one for positioning the opening of the plastic cloth of the air mattress and a positioning mechanism two for positioning the plastic connector of the inflating port to be welded are arranged directly below the high-frequency welding die.

[0008] By adopting the above technical solution, the positioning mechanism one and the positioning mechanism two are respectively used to position the opening of the plastic cloth and the plastic joint of the air inflation port, so that the plastic cloth of the air mattress and the plastic joint of the air inflation port can quickly reach the position directly below the high-frequency welding die without manual adjustment. Then, the longitudinal driving cylinder is used to drive the high-frequency welding die to move downward and weld and fix the plastic joint of the air inflation port and the opening of the plastic cloth. The positioning mechanism one and the positioning mechanism two can not only achieve the quick positioning of the opening of the plastic cloth and the plastic joint of the air inflation port, but also have high positioning accuracy, resulting in high operation efficiency, low manual labor intensity and good welding quality.

[0009] A further setting of the present utility model is that: the positioning mechanism one includes a positioning body whose cross-sectional shape matches the shape of the opening of the plastic cloth of the air mattress, and the bottom of the positioning body is fixed on the workbench.

[0010] By adopting the above technical solution, the positioning mechanism one uses the positioning body whose cross-sectional shape matches the shape of the opening of the plastic cloth of the air mattress to position the opening of the plastic cloth. When the opening of the plastic cloth needs to be positioned, it only needs to lay the plastic cloth on the workbench and then set the opening of the plastic cloth on the outer wall of the positioning body. The positioning process is simple and the operation is convenient.

[0011] A further setting of the present utility model is that: one or more cylinders with the same cross-sectional shape and different proportions can be sleeved outside the positioning body.

[0012] By adopting the above technical solution, one or more cylinders with the same cross-sectional shape and different proportions can be sleeved outside the positioning body, so that the positioning body can adapt to the positioning operations of the openings of plastic cloths of different sizes of air mattresses as needed, thereby effectively improving the versatility of the equipment.

[0013] A further setting of the present utility model is that: the positioning mechanism two includes a V-shaped block one and a V-shaped block two with opposite openings. The V-shaped block one and the V-shaped block two are respectively connected to the positioning driving mechanism through a horizontal slider one and a horizontal slider two. The horizontal slider one and the horizontal slider two are respectively in horizontal sliding fit with a slide seat one and a slide seat two fixed on the machine body.

[0014] By adopting the above technical solution, the positioning mechanism II uses the V-shaped block I and the V-shaped block II to position the inflatable port plastic joint. When the inflatable port plastic joint needs to be positioned, only need to place the inflatable port plastic joint between the V-shaped block I and the V-shaped block II, and then drive the V-shaped block I and the V-shaped block II respectively along the sliding seats I and II with the horizontal slider I and the horizontal slider II to slide in the direction of approaching each other through the positioning drive mechanism until the inflatable port plastic joint is clamped. At this time, the inflatable port plastic joint is exactly opposite to the high-frequency welding die, so the positioning operation of the inflatable port plastic joint is realized. At this time, starting the high-frequency welding die can realize the welding operation, and the inflatable port plastic joint is always clamped and fixed by the V-shaped block I and the V-shaped block II during the welding process and will not move randomly, so the reliability of the welding process is greatly improved.

[0015] The further setting of the present utility model is that: the positioning drive mechanism includes a rack I and a rack II symmetrically arranged on both sides of the telescopic shaft of the longitudinal drive cylinder and respectively fixedly connected to the telescopic shaft of the longitudinal drive cylinder. The rack I and the rack II are respectively meshed with a gear disc I and a gear disc II. The gear disc I and the gear disc II are respectively rotationally connected to the machine body through a rotating shaft I and a rotating shaft II. The gear disc I and the gear disc II are respectively connected to the horizontal slider I and the horizontal slider II through a driving rod I and a driving rod II.

[0016] One ends of the driving rod I and the driving rod II are respectively fixedly connected to the gear disc I and the gear disc II, and the other ends of the driving rod I and the driving rod II are respectively hinged to the horizontal slider I and the horizontal slider II through a connecting rod I and a connecting rod II.

[0017] By adopting the above technical solution, when the longitudinal driving cylinder drives the high-frequency welding die to move downward, the first rack and the second rack fixedly connected to the telescopic shaft of the longitudinal driving cylinder move downward synchronously. When the first rack and the second rack move downward synchronously, they respectively drive the first gear disk and the second gear disk to rotate relatively synchronously. When the first gear disk and the second gear disk rotate, they respectively drive the first horizontal slider and the second horizontal slider to move in the direction of approaching each other through the first driving rod and the second driving rod. When the first horizontal slider and the second horizontal slider move in the direction of approaching each other, they drive the first V-shaped block and the second V-shaped block to move in the direction of approaching each other until the plastic joint of the inflation port is clamped. At this time, the plastic joint of the inflation port is exactly located directly below the high-frequency welding die, and the bottom of the high-frequency welding die just abuts against the welding surface of the plastic joint of the inflation port. Start the high-frequency welding die to quickly weld the plastic joint of the inflation port onto the opening of the plastic cloth. When the welding operation is completed, control the telescopic shaft of the longitudinal driving cylinder to move in the reverse direction, thereby driving the high-frequency welding die to move upward. When the high-frequency welding die moves upward, it will separate from the plastic joint of the inflation port, and at the same time drive the first rack and the second rack to move upward synchronously. When the first rack and the second rack move upward synchronously, they respectively drive the first gear disk and the second gear disk to rotate reversely synchronously. When the first gear disk and the second gear disk rotate, they respectively drive the first horizontal slider and the second horizontal slider to move in the direction of moving away from each other through the first driving rod and the second driving rod. When the first horizontal slider and the second horizontal slider move in the direction of moving away from each other, they drive the first V-shaped block and the second V-shaped block to move in the direction of moving away from each other. When the first V-shaped block and the second V-shaped block move in the direction of moving away from each other, the welded plastic joint of the inflation port is loosened. The whole process is automatic, with a high degree of automation and low manual labor intensity.

[0018] The further setting of the present utility model is that: silicone rubber elastic pads are provided on the V-shaped surfaces of the first V-shaped block and the second V-shaped block.

[0019] By adopting the above technical solution, the setting of the silicone rubber elastic pads can greatly reduce the risk of damaging the plastic joint of the inflation port when the first V-shaped block and the second V-shaped block clamp and position the plastic joint of the inflation port, so the finished product rate of welding the plastic joint of the inflation port is greatly improved.

[0020] The further setting of the present utility model is that: the first sliding seat and the second sliding seat are both fixed on the side wall of one side of the machine body, and the gap between the bottom surfaces of the first V-shaped block and the second V-shaped block and the upper surface of the workbench is greater than the thickness of the plastic cloth of the air cushion bed and less than the height of the bottom of the high-frequency welding die during welding.

[0021] By adopting the above technical solution, the gap between the bottom surfaces of the first V-shaped block and the second V-shaped block and the upper surface of the workbench is greater than the thickness of the plastic sheet of the air cushion bed and less than the height of the bottom during high-frequency welding die welding, which can ensure that the first V-shaped block and the second V-shaped block can clamp and release the plastic joint of the inflation port by approaching or moving away from each other. At the same time, it can also ensure that the bottom surfaces of the first V-shaped block and the second V-shaped block do not contact the plastic sheet on the workbench during the process of approaching or moving away from each other, and will not cause wear or wrinkling of the plastic sheet, further ensuring the appearance quality of the product.

[0022] A further setting of the present utility model is that the high-frequency welding die is an annular structure matching the welding area of the plastic joint of the inflation port, and the high-frequency welding die is fixedly connected to the telescopic shaft of the longitudinal driving cylinder through a connecting column.

[0023] By adopting the above technical solution, the setting of the annular structure can not only effectively reduce the risk of interference between the high-frequency welding die and the plastic joint of the inflation port, but also ensure that a complete closed ring is formed in the welding area after the circumferential welding of the plastic joint of the inflation port by the high-frequency welding die. It not only has high welding efficiency, but also greatly reduces the risk of air leakage caused by the poor sealing of the welding surface of the plastic joint of the inflation port.

[0024] A further setting of the present utility model is that a condensation channel is embedded inside the high-frequency welding die, the condensation channel is communicated with a condensation pipe, and a condensation pump is provided on the condensation pipe.

[0025] By adopting the above technical solution, the condensation channel is used to quickly cool the welding area after welding is completed, avoiding the situation of cracking in the welding area due to untimely condensation, and further improving the welding effect of the plastic joint of the inflation port; the condensation pipe is used to convey the condensation liquid into the condensation channel when the welding area needs to be cooled after the high-frequency welding die welding is completed, so that the high-temperature high-frequency welding die can quickly cool down and quickly cool the welding area, ensuring that the plastic joint of the inflation port can be firmly fixed on the opening of the plastic sheet. After cooling, the condensation liquid in the condensation channel is discharged to facilitate the next hot melt welding operation.

[0026] The beneficial effects of the present utility model are:

[0027] 1. The utility model respectively uses the first positioning mechanism and the second positioning mechanism to position the opening of the plastic cloth and the plastic joint of the inflation port, so that the plastic cloth and the plastic joint of the inflation port of the air cushion bed can quickly reach the position directly below the high-frequency welding die without manual adjustment. Then, the longitudinal driving cylinder is used to drive the high-frequency welding die to move downward and weld and fix the plastic joint of the inflation port and the opening of the plastic cloth. The first positioning mechanism and the second positioning mechanism can not only quickly position the opening of the plastic cloth and the plastic joint of the inflation port, but also have high positioning accuracy, resulting in high operation efficiency, low manual labor intensity and good welding quality.

[0028] 2. In the utility model, the first positioning mechanism uses a positioning body that matches the shape of the opening of the plastic cloth of the air cushion bed to position the opening of the plastic cloth. When the opening of the plastic cloth needs to be positioned, it only needs to lay the plastic cloth on the workbench, and then set the opening of the plastic cloth on the outer wall of the positioning body. The positioning process is simple and the operation is convenient.

[0029] 3. One or more cylinders with the same cross-sectional shape but different proportions can be sleeved outside the positioning body of the utility model, so that the positioning body can adapt to the positioning operations of the openings of plastic cloths of air cushion beds of different sizes as required, thus effectively improving the versatility of the equipment.

[0030] 4. In the utility model, the second positioning mechanism uses the first V-shaped block and the second V-shaped block to position the plastic joint of the inflation port. When the plastic joint of the inflation port needs to be positioned, it only needs to place the plastic joint of the inflation port between the first V-shaped block and the second V-shaped block, and then drive the first V-shaped block and the second V-shaped block to slide along the first sliding seat and the second sliding seat in the direction of approaching each other respectively with the first horizontal slider and the second horizontal slider through the positioning driving mechanism until the plastic joint of the inflation port is clamped. At this time, the plastic joint of the inflation port is exactly opposite to the high-frequency welding die, so the positioning operation of the plastic joint of the inflation port is realized. At this time, starting the high-frequency welding die can realize the welding operation, and during the welding process, the plastic joint of the inflation port is always clamped and fixed by the first V-shaped block and the second V-shaped block and will not move randomly, so the reliability of the welding process is greatly improved.

[0031] 5. When the longitudinal driving cylinder in this utility model drives the high-frequency welding die to move downward, the first rack and the second rack fixedly connected to the telescopic shaft of the longitudinal driving cylinder move downward synchronously. When the first rack and the second rack move downward synchronously, they respectively drive the first gear disk and the second gear disk to rotate relatively synchronously. When the first gear disk and the second gear disk rotate, they respectively drive the first horizontal slider and the second horizontal slider to move towards each other through the first driving rod and the second driving rod. When the first horizontal slider and the second horizontal slider move towards each other, they drive the first V-shaped block and the second V-shaped block to move towards each other until the plastic joint of the inflation port is clamped. At this time, the plastic joint of the inflation port is exactly located at the position directly below the high-frequency welding die, and the bottom of the high-frequency welding die just abuts against the welding surface of the plastic joint of the inflation port. Start the high-frequency welding die to quickly weld the plastic joint of the inflation port onto the opening of the plastic cloth. After the welding operation is completed, control the telescopic shaft of the longitudinal driving cylinder to move in the reverse direction, thereby driving the high-frequency welding die to move upward. When the high-frequency welding die moves upward, it will separate from the plastic joint of the inflation port, and at the same time drive the first rack and the second rack to move upward synchronously. When the first rack and the second rack move upward synchronously, they respectively drive the first gear disk and the second gear disk to rotate in the reverse direction synchronously. When the first gear disk and the second gear disk rotate, they respectively drive the first horizontal slider and the second horizontal slider to move away from each other through the first driving rod and the second driving rod. When the first horizontal slider and the second horizontal slider move away from each other, they drive the first V-shaped block and the second V-shaped block to move away from each other. When the first V-shaped block and the second V-shaped block move away from each other, the welded plastic joint of the inflation port is loosened. The whole process is automatic, with a high degree of automation and low manual labor intensity.

[0032] 6. The gap between the bottom surfaces of the first V-shaped block and the second V-shaped block and the upper surface of the workbench in this utility model is greater than the thickness of the plastic cloth of the air cushion bed and less than the height of the bottom of the high-frequency welding die during welding, which can ensure that the first V-shaped block and the second V-shaped block can clamp and loosen the plastic joint of the inflation port by moving towards each other or away from each other. At the same time, it can also ensure that the bottom surfaces of the first V-shaped block and the second V-shaped block will not contact the plastic cloth on the workbench during the process of moving towards each other or away from each other, and will not cause wear or wrinkling of the plastic cloth, further ensuring the appearance quality of the product.
