Description

Technical Field

[0001] The invention relates to the technical field of welding of inflatable boats, and in particular to a welding machine for processing inflatable boats and a use method thereof. Background Art

[0002] An inflatable boat is a boat that uses multiple sets of inflatable tubes to provide buoyancy and stability. It is light, easy to carry, and highly stable. It is usually made of multiple layers of wear-resistant and corrosion-resistant polyvinyl chloride (PVC) materials. The PVC outer cover of the inflatable boat is usually welded at high temperature using a welding machine during processing to improve the sealing and durability of the outer cover of the inflatable boat.

[0003] Existing welding machines use a variety of methods to achieve the welding of the outer skin, such as a welding machine for processing inflatable boats with a publication number of CN117261247A, which relates to the technical field of welding machines, including a welding frame, a welding assembly is installed at one end of the welding frame, a feeding assembly is installed in the middle of the welding frame, a bottom plate is installed at the bottom of the feeding assembly, a universal rotating seat is installed at the top of one end of the bottom plate, and a mechanical arm is installed on the top of the universal rotating seat;

[0004] Due to the long length of the outer leather cover of the inflatable boat, the existing welding machine usually adopts a segmented heating welding method when welding the outer leather cover. This welding method is not only inefficient, but also the hot air during heating cannot be reused. For example, the above-mentioned referenced prior art uses a hot air blower and a high-speed fan to achieve heating and welding of the inflatable boat. The hot air generated after welding is directly discharged and cannot be fully utilized. In addition, the device only positions and drives the welding part of the inflatable boat. Due to the length and weight of the inflatable boat, the inflatable boat is prone to tilt due to uneven force when moving, resulting in insufficient stability of the welding part when it moves.

[0005] Therefore, it is urgent to design a welding machine for processing inflatable boats and a method of use to solve the above problems. Summary of the invention

[0024] S3. When the hot air flow generator is started, air is sucked in through the air intake assembly. At the same time, the air intake assembly generates negative pressure suction to adsorb the lower part of the outer leather cover, thereby improving the positioning stability of the outer leather cover;

[0025] S4. The hot air generated by the hot air flow generator will be sprayed to the welding part on the outer leather cover after passing through the air outlet heating component, and the welding part will be welded at high temperature. After welding, the pressure component will be started synchronously to apply stable pressure to the welding surface to promote the forming of the welding surface;

[0026] S5.

[0027] S6. After welding, the push assembly in the mobile pressurizing unit will start to move and adjust the position of the outer sleeve, so as to facilitate high-temperature welding of the next welding part. While the outer sleeve moves, the welding surface will be cut and trimmed with the cooperation of the air intake assembly to improve the uniformity and aesthetics of the welding surface.

[0028] The present invention provides a welding machine for processing an inflatable boat and a method of using the welding machine. The welding machine has the following beneficial effects:

[0029] 1. When welding an inflatable boat, the welding machine uses the adsorption limit wheel, the lower driving wheel, and the load-bearing front roller to cooperate with each other to support the lower part of the outer leather cover. At the same time, the upper pressure wheel is used to squeeze the upper part. Under the action of the servo motor, the outer leather cover of the inflatable boat can be stably moved, and the outer leather cover will not be offset during the welding movement.

[0030] 2. When welding inflatable boats, this welding machine can utilize the suction negative pressure effect generated by the hot air flow generator. When sucking air, negative pressure suction is generated through the multiple suction holes on the adsorption limit wheel, and the negative pressure suction is applied to the outer leather cover, so that the outer leather cover can be adsorbed and positioned, further improving its stability during welding.

[0031] 3. When the welding machine is welding the inflatable boat, the welding hood and the hot air flow generator are cooperated to make the high hot air generated by the hot air flow generator heat the welding part on the outer leather cover in the welding hood, so that the high hot air flows in the welding hood to improve the welding efficiency, and the welding hood can also play a role of heat preservation to avoid the waste of heat energy caused by the overflow of hot air during welding.

[0032] 4. When welding an inflatable boat, this welding machine can conduct the remaining hot air in the welding hood to the preheating hood, and through the cooperation of the cleaning bottom plate in the preheating hood, the preheating of the next welding part on the outer cover can be achieved, reducing the time for subsequent heating and welding, and cleaning the impurities attached to the outer cover to improve the cleanliness of the welding part.

[0033] 5. When welding inflatable boats, this welding machine can apply stable and balanced pressure to the welding parts through the cooperation of the hydraulic rod and the upper pressure wheel, which can effectively improve the density and strength of the welding surface of the welding part, promote the cooling and forming of the welding surface, and realize the cutting and trimming of the welding surface while the outer cover moves, thereby improving the uniformity and aesthetics of the welding surface.

[0034] To sum up, the present invention can utilize the negative pressure suction force generated by the hot air flow generator when sucking air to adsorb and position the outer leather cover, effectively improve the welding stability of the outer leather cover of the inflatable boat, and conduct the hot air generated by the hot air flow generator to the welding cover to perform cyclic heating and welding on the outer leather cover, which has a better heating effect. The remaining hot air after welding can also be conducted to the outer leather cover for preheating and impurity cleaning. The thermal energy utilization rate is higher, and the welding efficiency can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0049] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0050] Example 1: Reference Figure 1-Figure 3 A welding machine for processing an inflatable boat comprises a moving base 1 and an outer leather cover 4 of an inflatable boat to be welded, and further comprises:

[0051] The mobile pressurizing unit is used to realize the welding movement of the outer skin cover 4, and to pressurize the welding part after welding to improve the welding strength, so as to realize the stable movement of the outer skin cover 4 of the inflatable boat, so that it can quickly weld the next part after the welding of the previous part is completed, and can apply stable pressure to the welding surface after the welding is completed, so as to improve the density and strength of the welding surface and promote the cooling and forming of the welding surface.

[0052] A welding unit with a hot air flow generator 8 is provided, which is used to heat and weld the outer leather cover 4 and trim the welded part after welding. The welding unit can generate high-heat wind force under the action of the hot air flow generator 8 to heat the welded part on the outer leather cover 4, and the heating effect is better. After welding, the welded surface can be cut and trimmed to improve the uniformity and aesthetics of the welded surface;

[0053] The hot air flow generator 8 is a device for generating high-temperature air in the prior art, and is provided with an air inlet end for absorbing cold air and an air outlet end for blowing hot air. This part is the prior art and will not be described in detail here.

[0054] A support assembly is arranged on the moving base 1, and is used to support the mobile pressurizing unit and the welding unit. The support assembly includes a power supply box 2 arranged on the moving base 1, a support top rod 5 is fixedly installed on the power supply box 2, a support seat 10 is fixedly installed on the side of the power supply box 2, and a load-bearing front roller 3 and a load-bearing rear roller 9 are fixedly installed on the support seat 10;

[0055] A plurality of moving wheels are arranged at the lower part of the moving base 1, so as to realize the overall movement of the welding machine, which is more convenient and saves trouble. The power supply box 2 is used for supplying and distributing systematic electric energy to the electric equipment in the welding machine, effectively improving the safety and stability of electricity use.

[0056] The central control console 6 arranged on the supporting top rod 5 in the supporting assembly is used to control the opening and closing and operating status of the mobile pressurizing unit and the welding unit, so that the welding process of the outer leather cover 4 of the inflatable boat is more flexible and orderly, and the degree of automation of the welding process is improved.

[0057] Example 2: Reference Figure 2-Figure 5 The difference between this embodiment and the first embodiment is that the mobile pressurizing unit includes a pushing component and a pressing component, wherein the pushing component is used to realize the overall movement of the outer leather cover 4, and the pressing component is used to realize the positioning and welding pressurization of the outer leather cover 4;

[0058] The pushing assembly includes a servo motor 13 arranged on the front bearing roller 3, a driving roller 17 is fixedly mounted on the driving end of the servo motor 13, a lower driving wheel 11 is fixedly mounted on the driving roller 17, a driven roller 19 is rotatably mounted on the rear bearing roller 9, and a driven mechanism is installed between the driven roller 19 and the driving roller 17, and the driven mechanism includes an adsorption limiting wheel 14 fixedly mounted on the driven roller 19;

[0059] A transmission belt 18 is sleeved between the driven roller 19 and the driving roller 17, and the adsorption limit wheel 14, the lower driving wheel 11, and the load-bearing front roller 3 cooperate to support the outer leather cover 4, so that the outer leather cover 4 can be placed more stably to avoid uneven force.

[0060] The servo motor 13 drives the lower driving wheel 11 and the adsorption limiting wheel 14 to rotate to realize the movement of the outer leather cover 4. When the servo motor 13 is started, it drives the lower driving wheel 11 to rotate through the driving roller 17. When the driving roller 17 rotates, it drives the driven roller 19 to rotate through the transmission belt 18, thereby driving the adsorption limiting wheel 14 to rotate, and the adsorption limiting wheel 14 and the lower driving wheel 11 have the same rotation direction.

[0061] When the servo motor 13 is started, the lower driving wheel 11 and the adsorption limiting wheel 14 rotate together, thereby driving the outer leather cover 4 thereon to move, thereby realizing the automatic movement of the outer leather cover 4 .

[0062] The pressure assembly includes a hydraulic rod 7 fixedly mounted on the supporting top rod 5, a connecting frame 16 fixedly mounted on the driving end of the hydraulic rod 7, an upper pressure wheel 15 rotatably mounted on the connecting frame 16, and the upper pressure wheel 15 is located directly above the lower driving wheel 11;

[0063] After the outer leather cover 4 is placed, the hydraulic rod 7 can be started to drive the upper pressure wheel 15 to descend through the connecting frame 16 and fit with the upper part of the outer leather cover 4, so that the upper part of the outer leather cover 4 can be squeezed and limited, further improving its placement stability. At the same time, the squeezing of the outer leather cover 4 by the upper pressure wheel 15 can also play a role in limiting the outer leather cover 4, which can avoid the position displacement of the outer leather cover 4 when moving.

[0064] Example 3: Reference Figure 2-Figure 3 as well as Figure 6-Figure 12 The difference between this embodiment and the second embodiment is that the welding unit includes an air intake component and an air outlet heating component, wherein the air intake component is used to supplement the welding air and trim the welding part, and the air outlet heating component is used to heat the welding part and preheat the outer leather cover 4;

[0065] The air intake assembly includes a mounting frame fixedly mounted on the supporting top rod 5, a hot air flow generator 8 is arranged on the mounting frame, an air intake hose 12 is arranged on the air intake end, an air intake cone 24 is rotatably connected to the adsorption limiting wheel 14, and the air intake cone 24 is connected to the air intake hose 12, and a plurality of air intake holes 20 for air intake are opened on the adsorption limiting wheel 14;

[0066] When the hot air flow generator 8 is started, suction will be generated through the air inlet end thereof, thereby sucking external cold air into the hot air flow generator 8 through the air inlet hose 12, the air inlet cone 24, and the multiple air inlet holes 20 on the adsorption limit wheel 14, and then the hot air is discharged through the air outlet end after being heated inside the hot air flow generator 8;

[0067] When the multiple air inlet holes 20 on the adsorption limit wheel 14 are sucking air, negative pressure suction will be generated near the air inlet holes 20. Since the adsorption limit wheel 14 fits with the lower part of the outer leather cover 4, the air inlet holes 20 will firmly adsorb the outer leather cover 4 on the adsorption limit wheel 14 when sucking air, which can further improve the placement stability of the outer leather cover 4 and prevent it from moving during welding.

[0068] In a further embodiment, the air outlet heating assembly includes a welding cover 23 fixedly mounted on the connecting frame 16, and an air outlet hose 29 for conducting hot air is provided on the air outlet end of the hot air flow generator 8, and the other end of the air outlet hose 29 is fixedly connected to the welding cover 23;

[0069] The two side walls of the upper pressure wheel 15 are fitted with the welding cover 23. Fig.10 and Fig.11 It can be seen that the upper pressure wheel 15 is located in the welding cover 23 and is rotatably connected to the welding cover 23, that is, when the upper pressure wheel 15 rotates under the action of the movement of the outer leather cover 4, the welding cover 23 will not rotate, and if the upper pressure wheel 15 moves up and down under the action of the hydraulic rod 7, the welding cover 23 will move synchronously.

[0070] The hot air discharged from the outlet end of the hot air flow generator 8 will be directly conducted to the welding cover 23 through the outlet hose 29, so that the welding part on the outer leather sheath 4 in the welding cover 23 can be heated and welded. The welding cover 23 can block the hot air flow, so that the hot air flow can circulate in the welding cover 23 without escaping to the external air, thereby effectively increasing the temperature in the welding cover 23, improving the utilization rate of the hot air flow, and improving the efficiency of welding.

[0071] The welding hood 23 is provided with a preheating mechanism, which includes a preheating hood 22, and a gas collecting pipe 30 for hot air conduction is fixedly connected between the preheating hood 22 and the welding hood 23;

[0072] As the hot air flow is gradually injected, the front hot air flow heats the welding part on the outer leather cover 4, and then enters the preheating cover 22 through the air collecting pipe 30 on the welding cover 23. Since the preheating cover 22 is located above the rear area to be welded on the outer leather cover 4, the hot air entering the preheating cover 22 at this time will preheat the rear area to be welded on the outer leather cover 4, thereby increasing the temperature of the rear area of ​​the outer leather cover 4, reducing the welding heating time, and improving the welding efficiency.

[0073] A wind receiving plate 31 is slidably installed in the preheating cover 22 through the cooperation of two limit slide rails 34 and two limit slide blocks 35, and a return spring 32 is fixedly installed between the wind receiving plate 31 and the inner wall of the preheating cover 22, and a cleaning bottom plate 33 for cleaning impurities on the surface of the outer leather cover 4 is fixedly installed at the lower part of the wind receiving plate 31;

[0074] The hot air entering the preheating cover 22 through the air collecting pipe 30 will impact the wind receiving plate 31. When driven by the wind, the wind receiving plate 31 will slide on the limiting slide rail 34 with the cooperation of the two limiting slide blocks 35 (and will squeeze the return spring 32 at the same time). When the wind receiving plate 31 moves, it will drive the cleaning bottom plate 33 under it to move. When the cleaning bottom plate 33 moves, it will clean the part to be welded on the outer leather cover 4, thereby completing the automatic cleaning of the surface of the outer leather cover 4.

[0075] When the front welding area of ​​the outer leather cover 4 is welded, the hydraulic rod 7 will start to drive the upper pressure wheel 15 to move downward to apply a stable extrusion force to the welding surface, which can effectively improve the density and strength of the welding surface of the welding part and promote the cooling and forming of the welding surface. After the extrusion is completed, the outer leather cover 4 will move forward under the drive of the servo motor 13, and the hot air flow generator 8 will stop discharging air at this time;

[0076] When the hot air flow generator 8 stops discharging air, the air collecting pipe 30 will also stop injecting air into the preheating cover 22 synchronously. At this time, the reset spring 32 will automatically shrink and reset when not subject to wind force, thereby pushing the wind receiving plate 31 and the cleaning bottom plate 33 back to their original positions to complete the reset, so as to facilitate the cleaning of the next welding area.

[0077] The connecting frame 16 is provided with a trimming mechanism for trimming the weld surface of the outer leather cover 4, and the trimming mechanism includes a driven frame 26 fixedly mounted on the connecting frame 16, a cleaning box 21 is fixedly mounted on the driven frame 26, and a connecting hose 25 is fixedly connected between the cleaning box 21 and the intake cone 24, an intake grille 28 for absorbing impurities and air is provided on the cleaning box 21, and a cleaning blade 27 for trimming the weld surface is fixedly mounted at the lower part of the cleaning box 21;

[0078] The driven frame 26 moves up and down together with the connecting frame 16 under the action of the hydraulic rod 7. When the upper pressure wheel 15 moves down to squeeze the welding surface, the connecting frame 16 will drive the cleaning box 21 and the cleaning blade 27 to move down through the driven frame 26, and make the cleaning blade 27 fit with the outer leather cover 4.

[0079] When the pressurization is completed and the weld surface on the outer sheath 4 moves, when the weld surface moves to the lower part of the cleaning blade 27, the cleaning blade 27 will cut and trim the weld surface obliquely, and the burrs on the weld surface can be removed to keep the weld surface smooth and flat.

[0080] The burrs and impurities cleaned by the cleaning blade 27 will remain on the upper part of the cleaning blade 27. When the outer leather cover 4 is moved up and down to weld the welding area, the hot air flow generator 8 starts to inhale air through the air intake hose 12 and the air intake cone 24, and also inhales air through the connecting hose 25, the cleaning box 21 and the air intake grille 28. Since the air intake grille 28 is arranged on the upper part of the cleaning blade 27, the air intake grille 28 will absorb the impurities cleaned on the cleaning blade 27 into the cleaning box 21 when inhaling air, thereby completing the automatic collection of impurities and burrs.

[0081] A method for using a welding machine for processing an inflatable boat, which is used for the welding machine for processing an inflatable boat, comprises the following steps:

[0082] S1. When welding the outer cover 4 of the inflatable boat, first place the outer cover 4 on the upper part of the support assembly and the push assembly, and after adjusting the position, position the outer cover 4 by the pressure assembly, and at the same time adjust the position of the air inlet assembly and the air outlet heating assembly to make them fit with the welding part on the outer cover 4;

[0083] S2, start the hot air flow generator 8 in the welding unit through the central control console 6. When the hot air flow generator 8 is started, it will inhale cold air through the air inlet end and output high-temperature hot air through the air outlet end after heating it internally;

[0084] S3, when the hot air flow generator 8 is started, air is sucked in through the air intake assembly, and at the same time, the air intake assembly generates negative pressure suction force when sucking air to adsorb the lower part of the outer leather cover 4, thereby improving the positioning stability of the outer leather cover 4;

[0085] S4, the hot air generated by the hot air flow generator 8 will be sprayed to the welding part on the outer leather cover 4 after passing through the air outlet heating component, and the welding part will be welded at high temperature. After welding, the pressure applying component will be started synchronously to apply stable pressure to the welding surface to promote the forming of the welding surface;

[0086] S5. The hot air after welding is conducted to the next part to be welded on the outer jacket 4 through the air outlet heating assembly, so as to preheat and clean the surface of the next welding part, improve the welding efficiency of the next welding part, and improve the welding effect;

[0087] S6. After welding, the pushing component in the mobile pressurizing unit will start to move and adjust the position of the outer leather sleeve 4, so as to facilitate high-temperature welding of the next welding part. While the outer leather sleeve 4 moves, the welding surface will be cut and trimmed with the cooperation of the air intake component to improve the uniformity and aesthetics of the welding surface.

[0088] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
