Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, and particularly to welding equipment. Background Technology

[0002] A welding machine joins fabrics together by heating. For example, in related technologies, surfboards are made of brushed fabric, consisting of two layers of brushed fabric. An edging is then applied to the edges of the brushed fabric, and the edging and brushed fabric are connected by welding. By incorporating a heating element in the welding machine, the edging is conveyed to the welding area by a guide and conveyor. The heating element contacts the welding area between the edging and the brushed fabric; the welding area is where the edging and brushed fabric connect. After cooling, the edging and brushed fabric are sealed together.

[0003] In related technologies, the guide component and the conveyor component are fixedly connected. Adjusting the guide component can easily cause the conveyor component to deflect or move, requiring manual lifting of the conveyor component before adjusting the position of the guide component, which is a complex operation. It is difficult to guarantee the positional accuracy of the guide component and the conveyor component. When the edging is conveyed to the welding area, the relative position of the edging component and the drawing cloth will deviate, leading to quality problems such as gaps and misalignments at the weld, affecting the welding quality.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0024] A welding machine can be used to weld fabrics together, such as joining two pieces of fabric together. Figure 1 The drawing fabric 810 and the edging 830 are used in the process. For ease of explanation, subsequent embodiments will use welding. Figure 1 The following explanation uses the brushed fabric 810 and the edging 830 used in making surfboards as examples. The surfboard includes the brushed fabric 810 and the edging 830. There are two pieces of brushed fabric 810, and the edges of the two pieces of brushed fabric 810 are fitted with the edging 830. The edging 830 and the edges of the two pieces of brushed fabric 810 are sealed together, so that air can be blown into the inside of the surfboard to make it expand.

[0025] Therefore, such as Figures 2 to 5 As shown, the welding equipment proposed in this utility model includes: a frame 100, a first driving device 200, a second driving device 300, a first roller 110, a second roller 120, a heating device 400, and a feeding device 500. The first driving device 200 and the second driving device 300 are both connected to the frame 100. The first roller 110 and the second roller 120 are respectively connected to the first driving device 200 and the second driving device 300. The first driving device 200 can drive the first roller 110 to move towards or away from the second roller 120, and can also drive the first roller 110 to rotate. The second roller 120 is located below the first roller 110. A pressing area 130 for placing fabric 800 is formed between the first roller 110 and the second roller 120. The pressing area 130 holds a drawing cloth 810 and an edging cloth 830.

[0026] Specifically, refer to Figure 2 and Figure 3As shown, the heating device 400 is connected to the first driving device 200 and the second driving device 300 to drive the heating device 400 to move towards or away from the pressing area 130. For example, the heating device 400 includes a first hot air connector 420 and a second hot air connector 430. The first hot air connector 420 is connected to the first driving device 200, and the second hot air connector 430 is connected to the second driving device 300. Both the first hot air connector 420 and the second hot air connector 430 can blow hot air for welding. Hot air welding has advantages such as high speed, high quality, and the fabric 800 is not easily deformed, effectively improving the situation of carbon accumulation and deformation of the fabric 800. It should be noted that the purpose of setting the first hot air connector 420 and the second hot air connector 430 is to simultaneously weld the edging 830 and the two pieces of drawing cloth 810 to improve processing efficiency. In another embodiment, the heating device 400 is connected to the first driving device 200, and may only have a first hot air connector 420 connected to the first driving device 200; or the heating device 400 is connected to the second driving device 300, i.e., may only have a second hot air connector 430 connected to the second driving device 300. It should be noted that, besides using hot air for welding, direct heating with a heating element is also possible, depending on the specific circumstances. For ease of explanation, all subsequent embodiments of this utility model will be explained using the heating device 400 including a first hot air connector 420 and a second hot air connector 430 as an example.

[0027] Because heat dissipates easily, wrinkles and shiny edges may appear in areas where welding is not required. To improve this situation, in some embodiments of this utility model, such as... Figure 3As shown, the frame 100 is equipped with air outlet pipes for blowing air onto the fabric 800. The air outlet pipes blow air towards the edge of the welding area of ​​the fabric 800, which refers to the area where the drawing fabric 810 and the binding 830 are connected. There are multiple air outlet pipes, including a first air outlet pipe 710 and a second air outlet pipe 720. The first air outlet pipe 710 is connected to the first drive device 200, and its outlet end is located near the first roller 110, allowing it to move with the first roller 110. The first air outlet pipe 710 blows air towards the upper surface of the drawing fabric 810, which is beneficial for heat dissipation in the non-welding area of ​​the drawing fabric 810. The second air outlet pipe 720 is connected to the frame 100, and its outlet end is located near the second roller 120. The second air outlet pipe 720 blows air towards the lower surface of another piece of drawing fabric 810. It is understandable that the first air outlet pipe 710 and the second air outlet pipe 720 are respectively located near the first roller 110 and the second roller 120. The first roller 110 and the second roller 120 press the welding area together. Therefore, the first air outlet pipe 710 and the second air outlet pipe 720 have little impact on the welding area when blowing air, and will not cause the welding area to solidify before the edge binding 830 and the wire drawing cloth 810 are fully connected.

[0028] The feeding device 500 is mounted on the frame 100. The feeding device 500 includes a guide 510 and a transmission assembly 520. One end of the edge banding 830 extends to the transmission assembly 520, which transmits the edge banding 830 to the guide 510. The guide 510 bends the edge banding 830 and guides it to the pressing area 130. Both the transmission assembly 520 and the guide 510 are mounted on the frame 100, allowing for independent position adjustments without interference. This improves the accuracy of the fabric transmission, avoids gaps and misalignments in the welding process, and ultimately enhances the welding quality.

[0029] In some embodiments of this utility model (not shown in the figures), a third air outlet pipe is provided on the side of the guide member 510 facing the pressing area 130. The third air outlet pipe is used to blow air into the interior of the fabric 800. The interior of the fabric 800 refers to the area between the two pieces of fabric 810 and the edging 830. Since the surfboard needs to be inflated during use, the edging 830 itself cannot stick together, which would cause the surfboard to deform. Therefore, during the processing, the air outlet end of the third air outlet pipe is located inside the edging 830 and blows air into the inside of the edging 830 to accelerate heat dissipation and prevent the upper section 831 and the lower section 832 of the edging 830 from sticking together.

[0030] In some embodiments of this utility model, reference is made to Figures 2 to 6As shown, the transmission assembly 520 includes a first conveying roller 521 and a second conveying roller 522. The diameter of the second conveying roller 522 is larger than the diameter of the first conveying roller 521. The first conveying roller 521 is rotatably connected to the frame 100 and can rotate around its own axis. The second conveying roller 522 is movably connected to the frame 100. A guide channel is formed between the first conveying roller 521 and the second conveying roller 522. The first conveying roller 521 and the second conveying roller 522 cooperate to achieve rapid material transfer.

[0031] In some embodiments of this utility model, reference is made to Figures 2 to 6 As shown, the frame 100 is provided with a mounting groove 140, which extends along the arrangement direction of the first conveying roller 521 and the second conveying roller 522. A connecting rod 523 passes through the middle of the second conveying roller 522 and is installed in the mounting groove 140. An elastic element is connected to the groove wall of the mounting groove 140. The elastic element abuts against the connecting rod 523, allowing the second conveying roller 522 to float radially. Under the force of the elastic element, the second conveying roller 522 cooperates with the first conveying roller 521 to press against the material, preventing wrinkles from appearing on the edge 830. At the same time, the gap between the two conveying rollers can be flexibly changed according to the thickness, hardness, and other characteristics of the material, thereby ensuring that different types of materials can be stably clamped and conveyed.

[0032] In some embodiments of this utility model, reference is made to Figures 2 to 6 As shown, the first conveying roller 521 has limiting portions 5211 at both ends to restrict the axial movement of the second conveying roller 522. The distance between the limiting portions 5211 is greater than the length of the second conveying roller 522. It can be understood that the distance between the limiting portions 5211 is slightly greater than the total length of the second conveying roller 522, which both reserves a small space for the axial movement of the second conveying roller 522 to avoid jamming and limits the axial movement range of the second conveying roller 522 through the blocking effect of the limiting portions 5211. When the second conveying roller 522 tends to displace axially due to the lateral force during transmission by the edge banding 830, the limiting portions 5211 of the first conveying roller 521 will effectively block the movement at both ends of the second conveying roller 522, thereby improving the conveying stability of the transmission assembly 520.

[0033] In some embodiments of this utility model, such as Figure 3As shown, the welding equipment also includes a first rolling bearing 150 and a second rolling bearing 160. The first rolling bearing 150 and the second rolling bearing 160 are longitudinally spaced apart on the frame 100, with the second rolling bearing 160 located below the first rolling bearing 150. The first rolling bearing 150 and the second rolling bearing 160 are rotatably connected to the frame 100, forming a limiting space between them to restrict the movement of the fabric 800. Both the first rolling bearing 150 and the second rolling bearing 160 are equipped with multiple balls to make the drawing cloth 810 move more smoothly during the dragging process, reducing jamming and other issues, facilitating the rotational welding of the drawing cloth 810, and improving the operator's experience.

[0034] Furthermore, in some embodiments of this utility model, it is understood that there are two second rolling bearings 160. The two rolling bearings are arranged along the length direction of the guide member 510, which can enhance the support for the fabric 800 below. The two second rolling bearings 160 can increase the contact area with the fabric 800, avoid the fabric 800 from sagging or shifting due to insufficient support, form a more balanced support force, and further optimize the limiting effect.

[0035] In some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, the feeding device 500 also includes a feeding turntable 530 and two limiting members 540, forming a conveying gap between them. The feeding turntable 530 and the limiting members 540 are spaced apart. An edge banding 830 is wound around the feeding turntable 530. The limiting members 540 are positioned between the feeding turntable 530 and the guide member 510, and are fixedly connected to the frame 100. It is understood that when the edge banding 830 is pulled out from the feeding turntable 530, it will first pass through the limiting members 540. Under the constraint of the limiting members 540, the edge banding 830 will move along a preset trajectory, preventing deviation during conveying.

[0036] In some embodiments of this utility model, such as Figure 2 and Figure 4 As shown, the guide member 510 is rotatably connected to the side facing the limiting member 540 with a guide wheel 511. When the edge banding 830 is on the guide member 510, the edge banding 830 rolls with the guide wheel, thereby reducing the friction between the edge banding 830 and the guide part, making the edge banding 830 feed more smoothly and effectively reducing the situation of the edge banding 830 getting stuck.

[0037] In some embodiments of this utility model, such as Figures 4 to 6As shown, the guide member 510 has an arc-shaped surface, and a stop 512 is provided on the side of the guide member 510 facing the pressing area 130. The stop 512 is used to separate the two side segments of the edging 830. During processing, the stop 512 is also located on the inner side of the edging 830. The stop 512 is used to separate the upper side segment 831 and the lower side segment 832 of the edging 830, further reducing the possibility of the upper side segment 831 and the lower side segment 832 sticking together. It should be noted that the stop 512 can be sickle-shaped to match the shape of the edging 830 after bending, improving the smoothness of the movement of the edging 830.

[0038] In other embodiments of this utility model, such as Figure 7 As shown, the guide member 510 has a diamond-shaped surface facing the pressing area 130. The end of the guide member 510 does not require a guide wheel 511, nor does it require a first conveying roller 521 or a second conveying roller 522. When the edge banding 830 contacts the diamond-shaped surface, it gradually changes its bending angle along the inclined edge. This progressive guidance prevents the edge banding 830 from wrinkling, creases, or material damage due to excessive instantaneous force, ensuring a natural and regular shape after bending. Multiple limiting members 540 are also provided between the guide member 510 and the feeding turntable 530. When the edge banding 830 is pulled out from the feeding turntable 530, it first passes through the limiting members 540. Under the constraint of the limiting members 540, the edge banding 830 moves along a preset trajectory, stably conveying towards the guide member 510, preventing deviation during conveying, and forming a guiding path conducive to the bending of the edge banding 830.

[0039] In some embodiments of this utility model, reference is made to Figures 2 to 6 As shown, the front end of the guide 510 is inclined towards the transmission assembly 520, thus providing sufficient space for the operator to facilitate the welding of the wire drawing cloth 810 and the edge binding 830, improving the operator's user experience. The guide 510 is manufactured using wire cutting technology, which offers high processing precision, ensuring that the dimensional and shape tolerances of the guide 510 are controlled within a very small range, and that the surface roughness is low. This helps to avoid frictional resistance and wear caused by surface roughness during transmission, and prevents positional deviation of the guide 510 due to insufficient processing precision, thereby ensuring the transmission stability of the wire drawing cloth 810 and the edge binding 830.

[0040] In some embodiments of this utility model, such as Figure 6As shown, the guide member 510 is connected to a first connector 170, which has a first connecting groove 171 extending longitudinally. The guide member 510 can be adjusted in position along the extension direction of the first connecting groove 171. A second connector 180 is fixedly connected to the first connector 170, which has a second connecting groove 181 extending along the length of the guide member 510. A third connector 190 is connected to the second connector 180 and is connected to the frame 100. The second connecting groove 181 cooperates with a fastener to fix the second connector 180 to the third connector 190. The second connector 180 can be adjusted in position along the extension direction of the second connecting groove 181, thereby adjusting the front-rear position of the guide member 510. The third connector 190 is provided with a third connecting groove 191, which cooperates with a fastener to fix the third connector 190 to the frame 100. The third connector 190 can move along the extension direction of the third connecting groove 191 to adjust the fixed position of the third connector 190, thereby adjusting the left and right position of the guide 510. The fastener can be a quick-adjusting wrench, which can be quickly loosened by a simple turn, and tightened by turning it in the opposite direction after the position is adjusted.

[0041] In some embodiments of this utility model, reference is made to Figure 2 and Figure 5 As shown, the first driving device 200 includes a first motor 210, a first cylinder 220, a second cylinder 230, and a third cylinder 240. The first motor 210 and the first cylinder 220 are both driven and connected to the first roller 110. The first motor 210 is used to drive the first roller 110 to rotate, and the first cylinder 220 is used to drive the first roller 110 to move in the up-down direction. The second cylinder 230 and the third cylinder 240 are both driven and connected to the first hot air connector 420. The second cylinder 230 is used to drive the first hot air connector 420 to move in the up-down direction, and the third cylinder 240 is used to drive the first hot air connector 420 to move in the left-right direction.

[0042] In some embodiments of this utility model, reference is made to Figure 2 and Figure 5 As shown, the second drive device 300 includes a second motor 310, a fifth cylinder 320, and a sixth cylinder 330. The second motor 310 is driven to rotate by the second roller 120. The fifth cylinder 320 and the sixth cylinder 330 are both driven to move the second hot air connector 430. The fifth cylinder 320 is used to drive the second hot air connector 430 to move in the up and down direction, and the sixth cylinder 330 is used to drive the second hot air connector 430 to move in the left and right direction.

[0043] It is understandable that the temperature of the first hot air connector 420 is relatively high, and it is prone to contact with the non-welding area of ​​the drawing cloth 810 during its movement to the right, causing deformation of the drawing cloth 810 and affecting product quality. Therefore, in some embodiments of this utility model, such as Figure 3 As shown, the welding equipment also includes a first protective plate 410, which is connected to the first driving device 200 or the frame 100. The heating device 400 includes a first hot air connector 420, which can abut against the upper surface of the first protective plate 410. For example, the first protective plate 410 is driven by the first cylinder 220 of the first driving device 200, which can drive the first protective plate 410 to move in the vertical direction. When welding is required, the first protective plate 410 is located near or abuts against the drawing cloth 810, while the first hot air connector 420, when descending, can first contact the upper surface of the first protective plate 410 before moving to the position where the drawing cloth 810 and the edge banding 830 need to be welded. This effectively reduces the contact between the first hot air connector 420 and the non-welding area of ​​the drawing cloth 810, thereby improving product quality.

[0044] In some embodiments of this utility model, such as Figure 2 As shown, the welding equipment also includes a worktable 600 for supporting the drawing cloth 810. The worktable 600 is equipped with a second protective plate 610, located below the first protective plate 410. The heating device 400 also includes a second hot air connector 430 connected to a second driving device 300. The second hot air connector 430 can abut against the lower end face of the second protective plate 610. During processing, as the second hot air connector 430 moves, it can first abut against the second protective plate 610 before moving to the welding area, thereby preventing the second hot air connector 430 from directly contacting the non-welding area of ​​the drawing cloth 810, thus ensuring the quality of the drawing cloth 810.

[0045] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
