The welder may be used to weld two cloths, for example, to join two cloths, or may be used to weld the wiredrawing cloth 910 and the selvedge 930 of fig. 1. For convenience of explanation, the drawing cloth 910 and the wrapping 930 for manufacturing the surfboard in fig. 1 are welded in the following embodiments. The surfboard comprises two wire drawing cloths 910 and a binding 930, wherein the two wire drawing cloths 910 are provided with the binding 930 at the edges of the two wire drawing cloths 910, the binding 930 is in sealing connection with the edges of the two wire drawing cloths 910, and then the inner part of the surfboard can be inflated.

In order to weld the binding 930 to the wiredrawing fabric 910, referring to fig. 2 and 3, a welding machine 1000 according to an embodiment of the present utility model includes a frame 100, a first driving device 200, a second driving device 300, a first roller 130, a second roller 140, and a heat generating device 400. The first driving device 200 and the second driving device 300 are both connected to the frame 100 and are disposed at intervals along the up-down direction, for example, the first driving device 200 is located above the second driving device 300. The first driving device 200 is in driving connection with the first roller 130, for example, drives the first roller 130 to rotate, and can drive the first roller 130 to move along the up-down direction. The second driving device 300 is in driving connection with the second roller 140 to drive the second roller 140 to rotate, and the second roller 140 is located below the first roller 130. A press-fit area 150 is formed between the first roller 130 and the second roller 140, and the wire-drawing cloth 910 and the selvedge 930 are placed on the press-fit area 150.

Referring to fig. 3, the heat generating device 400 is connected to the first driving device 200 and the second driving device 300. For example, the heat generating device 400 includes a first hot air joint 410 and a second hot air joint 420, the first hot air joint 410 is connected to the first driving device 200, and the second hot air joint 420 is connected to the second driving device 300. The first hot air connector 410 and the second hot air connector 420 can both blow hot air to weld, and the hot air welding has the advantages of high speed, high quality, difficult deformation of the cloth 900 and the like, and effectively improves the conditions of carbon deposition, deformation and the like of the cloth 900. The first hot air connector 410 and the second hot air connector 420 are provided to weld the selvedge 930 and the two wire-drawn cloths 910 at the same time, so as to improve the processing efficiency. In another embodiment, only the first hot air connector 410 may be connected to the first driving device 200, or only the second hot air connector 420 may be connected to the second driving device 300. Of course, instead of the method of welding with hot air, a method of directly heating by a heat generating sheet may be adopted, and a suitable scheme may be specifically selected according to actual circumstances. For convenience of explanation, in all the following embodiments of the present utility model, the heat generating device 400 includes the first hot air connector 410 and the second hot air connector 420.

Because the heat is easy to dissipate, the parts which do not need welding have the conditions of folds, bright edges and the like. To improve this, the welder 1000 further includes a heat sink for blowing air toward the edge of the welding area of the cloth 900. The welding zone refers to: the region where the cloth 910 and the selvedge 930 are connected, that is, the region where the heating device 400 melts part of the structures of the cloth 910 and the selvedge 930 when heated.

The general workflow of the fusion machine 1000 is: two pieces of wiredrawing cloth 910 and a binding 930 are arranged in the pressing area 150, the first roller 130 moves downwards under the drive of the first driving device 200, and the wiredrawing cloth 910 and the binding 930 are pressed together through the cooperation of the first roller 140 and the second roller 140. The first hot air connector 410 and the second hot air connector 420 are driven by the first driving device 200 and the second driving device 300 to move to the front of the first roller 130 and the second roller 140, respectively heat and melt the positions between the two wire drawing cloths 910 and the edging 930 to be connected, and then drive the wire drawing cloths 910 and the edging 930 to move from front to back under the rotation of the first roller 130 and the second roller 140. In the moving process, the first roller 130 and the second roller 140 can press the welding area, so that the connection between the wiredrawing fabric 910 and the edging 930 is more stable. Near the first roller 130 and the second roller 140, the heat dissipating device blows air towards the edge of the welding area, so that heat can be rapidly dissipated into the surrounding air, the situations that folds, bright edges and the like occur at the edge of the welding area are effectively reduced, the attractiveness is high, and the product quality can be improved.

With continued reference to fig. 3, in the embodiment of the utility model, the heat dissipating device includes a first air outlet pipe 510 and a second air outlet pipe 520, where the first air outlet pipe 510 is connected to the first driving device 200, and an air outlet end of the first air outlet pipe 510 is located near the first roller 130, and the air outlet end can move along with the first roller 130. The first air outlet pipe 510 can blow air towards the upper end surface of the wiredrawing fabric 910, which is beneficial to heat dissipation in the non-welding area of the wiredrawing fabric 910. The second air outlet pipe 520 is connected with the frame 100, the air outlet end of the second air outlet pipe 520 is located at a position close to the second roller 140, and the second air outlet pipe 520 can blow air towards the lower end face of the other piece of wire drawing cloth 910. It can be appreciated that the first air outlet pipe 510 and the second air outlet pipe 520 are respectively disposed at positions close to the first roller 130 and the second roller 140, and the first roller 130 and the second roller 140 press the welding area, so that the first air outlet pipe 510 and the second air outlet pipe 520 have less influence on the welding area when blowing air, and the welding area is not solidified before the edging 930 and the wiredrawing cloth 910 are completely connected. Therefore, the positions of the first air outlet pipe 510 and the second air outlet pipe 520 are arranged reasonably, and the structure is simple and reliable. The first air outlet pipe 510 and the second air outlet pipe 520 are tubular, so that heat dissipation can be performed on corresponding positions in a targeted manner, and the heat dissipation effect is improved.

Referring to fig. 2 and 4, in the embodiment of the present utility model, the welding machine 1000 further includes a feeding device 600, and the feeding device 600 is used for conveying the hemming 930. For example, the feeding device 600 includes a feeding turntable 620 and a guide 630, and the feeding turntable 620 and the guide 630 are connected to the frame 100 and spaced apart. The feeding turntable 620 is wound with a wrapping edge 930, one end of the wrapping edge 930 is led out to the guiding part 630, and the wrapping edge 930 is led to the pressing area 150 through the guiding part 630. A third air outlet pipe 530 is provided at a rear end of the guide portion 630, i.e., an end facing the nip 150, and the third air outlet pipe 530 is used for blowing air toward the inside of the cloth 900. The interior of the cloth 900 refers to the area between the two wiredrawing cloths 910 and the selvedge 930. Because the surfboard needs to be inflated when in use, the selvedges 930 cannot adhere to each other, resulting in deformation of the surfboard. Therefore, during the processing, the air outlet end of the third air outlet pipe 530 is located at the inner side of the edging 930, and blows air towards the inner side of the edging 930 to accelerate heat dissipation, so as to prevent the upper edge 931 and the lower edge 932 of the edging 930 from adhering.

Referring to fig. 4, in the embodiment of the present utility model, the feeding device 600 further includes a guide wheel 640, the guide wheel 640 is rotatably connected to the guide portion 630, and the guide wheel 640 is located at an end of the guide portion 630 near the pressing area 150. When the edge cover 930 is arranged on the guide part 630, the edge cover 930 is in rolling fit with the guide wheel 640, so that friction force between the edge cover 930 and the guide part 630 is reduced, feeding of the edge cover 930 is smoother, and blocking of the edge cover 930 is effectively reduced.

Referring to fig. 4, in the embodiment of the present utility model, the feeding device 600 is further provided with a blocking portion 610, and the blocking portion 610 is located at an end of the feeding device 600 facing the lamination area 150. During processing, the blocking portion 610 is also located inside the edge 930, for example, at the rear end of the third air outlet duct 530. The stop 610 is used to separate the upper and lower sections 931, 932 of the flange 930 to further reduce the adhesion of the upper and lower sections 931, 932. It should be noted that, the blocking portion 610 may be in a sickle shape, and is matched with the shape of the folded edge 930, so as to improve the smoothness of the folded edge 930 during moving.

Referring to fig. 2, in the embodiment of the present utility model, the front end of the guiding portion 630 is obliquely disposed towards the direction of the feeding turntable 620, so that enough space is reserved for an operator, welding of the wire drawing cloth 910 and the edging 930 is facilitated, and the use experience of the operator is improved.

When the welding is suspended, the first hot air joint 410 and the second hot air joint 420 continue to emit hot air. However, when the welding is suspended, the operator often adjusts the positions of the drawing cloth 910 and the selvedge 930, so that the operator is easily scalded by hot air. For this reason, referring to fig. 5, in the embodiment of the utility model, the welding machine 1000 further includes an air guiding pipe 700, and one end of the air guiding pipe 700 is disposed towards the first hot air connector 410 and/or the second hot air connector 420, so as to guide the hot air to other positions, thereby effectively reducing the situations that the hot air scalds the operator.

With continued reference to fig. 5, in the embodiment of the present utility model, the first driving device 200 includes a first motor 210, a first cylinder 220, a second cylinder 230 and a third cylinder 240, where the first motor 210 and the first cylinder 220 are both connected to the first roller 130 in a driving manner, the first motor 210 is used to drive the first roller 130 to rotate, and the first cylinder 220 is used to drive the first roller 130 to move in an up-down direction; the second air cylinder 230 and the third air cylinder 240 are both in driving connection with the first hot air joint 410, the second air cylinder 230 is used for driving the first hot air joint 410 to move in the up-down direction, and the third air cylinder 240 is used for driving the first hot air joint 410 to move in the left-right direction.

The second driving device 300 includes a second motor 310, a fifth cylinder 320 and a sixth cylinder 330, the second motor 310 is in driving connection with the second roller 140 to drive the second motor 310 to rotate, the fifth cylinder 320 and the sixth cylinder 330 are both in driving connection with the second hot air joint 420, the fifth cylinder 320 is used for driving the second hot air joint 420 to move in the up-down direction, and the sixth cylinder 330 is used for driving the second hot air joint 420 to move in the left-right direction.

Thus, the operation of the fusion machine 1000 may be: the hemming 930 is guided to the nip 150 by the feeding device 600, the wire drawing cloth 910 is also disposed in the nip 150, and then, referring to fig. 6, the first cylinder 220 drives the first roller 130 to move downward to nip the wire drawing cloth 910 and the hemming 930. When the first roller 130 moves downward, the first air outlet pipe 510 moves downward synchronously. Referring next to fig. 7, the second air cylinder 230 drives the first hot blast joint 410 to move downward. Finally, referring to fig. 8 again, when the first hot air connector 410 is moved rightward by the third air cylinder 240 when the first hot air connector 410 approaches the wiredrawing cloth 910, the first hot air connector 410 is positioned between the wiredrawing cloth 910 and the edging 930, and then the wiredrawing cloth 910 and the edging 930 are heated in the area to be connected. The movement logic of the second hot air connector 420 is similar to that of the first hot air connector 410, and the main difference is that the second hot air connector 420 and the first hot air connector 410 do mirror image movement, which is not described herein. By adopting the scheme, the operation modes of welding the wiredrawing cloth 910 and the edge cover 930 are simple and convenient, and the production efficiency can be improved.

It will be appreciated that the temperature of the first hot air connector 410 is relatively high, and the hot air connector is easily contacted with the non-welding area of the wiredrawing fabric 910 during the rightward movement, so that deformation and the like are generated on the wiredrawing fabric 910, which affects the product quality. Accordingly, referring to fig. 3, in the embodiment of the present utility model, the welding machine 1000 further includes a first shielding sheet 120, and the first shielding sheet 120 is connected to the first driving device 200 or is connected to the frame 100. For example, the first protection sheet 120 is drivingly connected to the first cylinder 220 of the first driving device 200, and the first cylinder 220 can drive the first protection sheet 120 to move in the up-down direction. When welding is required, the first protection sheet 120 is located at a position close to the wire drawing cloth 910 or is abutted against the wire drawing cloth 910, and when the first hot air connector 410 descends, the first hot air connector can be contacted with the upper end surface of the first protection sheet 120 and then moved to a position where the wire drawing cloth 910 and the wrapping 930 need to be welded, so that the contact condition between the first hot air connector 410 and a non-welding area of the wire drawing cloth 910 is effectively reduced, and the product quality is improved.

Referring to fig. 2 and 3, in an embodiment of the present utility model, the fusion machine 1000 further includes a table 800, and the table 800 is used to support the wiredrawing fabric 910. The workbench 800 is provided with a second protective sheet 810, and the second protective sheet 810 is positioned below the first protective sheet 120. In the process of processing, the second protection sheet 810 can play a role in supporting the wiredrawing cloth 910, and in the moving process of the second hot air connector 420, the second hot air connector 420 can be firstly abutted with the second protection sheet 810 and then moved to the position of the welding area, so that the second hot air connector 420 is prevented from directly contacting the non-welding area on the wiredrawing cloth 910, and the quality of the wiredrawing cloth 910 is ensured.

Referring to fig. 2, in the embodiment of the present utility model, a plurality of balls 820 are disposed on an upper end surface of the working table 800 at intervals, so that the wire drawing cloth 910 is smoother in the dragging process, the conditions of jamming, blocking and the like are reduced, the wire drawing cloth 910 is convenient to be welded in a rotating manner, and the operation experience of operators is improved.

Referring to fig. 5, in the embodiment of the present utility model, the fusion machine 1000 further includes a stage 110, where the stage 110 is connected to the frame 100 and is located near the first roller 130 and the second roller 140, and the stage 110 is used for supporting the wiredrawing fabric 910 and the selvedge 930. When the edge 930 needs to be welded at the arc position of the wiredrawing cloth 910, the objective table 110 can facilitate the rotation of the wiredrawing cloth 910, simplify the operation, and improve the yield.

Referring to fig. 9, 10 and 11, in the embodiment of the present utility model, the first driving device 200 is provided with a mounting plate 190, and the welding machine 1000 further includes a connecting member 180, a first pressing wheel 160 and a second pressing wheel 170, and a guide post 182 is provided at an upper end of the connecting member 180, where the guide post 182 is cylindrical. The connecting member 180 is rotatably connected to the mounting plate 190 through the guide post 182, and the first pressing wheel 160 is rotatably connected to the connecting member 180, for example, the first pressing wheel 160 is connected to the lower end of the connecting member 180. Second puck 170 is coupled to second drive device 300 and is positioned below first puck 160. Second puck 170 may be positioned coaxially with second scroll wheel 140. A limit space for limiting the position of the selvedge 930 is also formed between the first pinch roller 160 and the second pinch roller 170.

It will be appreciated that first drive 200 may drive mounting plate 190, link 180, and first puck 160 together in a direction toward second puck 170, e.g., downward, during operation of welder 1000. The wiredrawing cloth 910 is located in a limiting space between the first pressing wheel 160 and the second pressing wheel 170, and the first pressing wheel 160 and the second pressing wheel 170 are respectively abutted against the upper side and the lower side of the edge covering 930, so that the relative position between the edge covering 930 and the wiredrawing cloth 910 is limited, and the situation that the welding is unstable due to the fact that the edge covering 930 is blown by hot air and the wiredrawing cloth 910 is separated too far is avoided. The second driving device 300 can drive the second pressing wheel 170 to rotate, and the rotation speed of the second pressing wheel 170 can be the same as that of the second roller 140, so that the wire drawing cloth 910 is driven to move by matching with the first roller 130 and the second roller 140. When the wiredrawing fabric 910 moves, the first pressing wheel 160 can be driven to rotate along the circumferential direction. Since the wire drawing cloth 910 can be used to make a surfboard, the edges of the surfboard are joined together in a loop. Thus, in welding the binding 930, it is necessary to control the wire wrap 910 to turn to accommodate the shape of the surfboard. When the wire drawing cloth 910 is rotated, the first pressing wheel 160 can rotate along the circumferential direction of the guide post 182 together with the connecting piece 180 under the driving of the wire drawing cloth 910, so that the effect of assisting the wire drawing cloth 910 in turning is achieved, and the smoothness of the wire drawing cloth 910 in turning is improved.

Referring to fig. 11, in the embodiment of the present utility model, a blocking piece 192 is provided at the lower end of the mounting plate 190, and a torsion spring 181 is sleeved on the guide post 182, where the torsion spring 181 is located between the mounting plate 190 and the connector 180. The torsion spring 181 has a protruding end 1811, and the protruding end 1811 abuts against the catch 192 to provide a restoring force for restoring the link 180 to the original position. For example, two blocking pieces 192 are provided and are spaced along the axial direction of the first roller 130, and the connecting member 180 may be located between the two blocking pieces 192. When the rotational amplitude of the link 180 is excessively large, the link 180 may abut against the stopper 192, thereby limiting the range of rotation thereof. A nut 191 is threadedly coupled to the upper end of the guide post 182 to fix the relative position between the guide post 182 and the mounting plate 190. The protruding end 1811 may be abutted against one of the blocking pieces 192, and since the torsion spring 181 has elasticity, when the first pressing wheel 160 is not acted on by an external force, the elasticity of the torsion spring 181 may enable the connecting member 180 to be maintained at the initial position, so that welding of the wire drawing cloth 910 and the wrapping edge 930 is facilitated. For example, the initial position may be a position where the first pinch roller 160 and the first roller 130 are coaxial, or may be a position where the central axes of the first pinch roller 160 and the second roller 140 are disposed at an angle, and an appropriate scheme is specifically selected according to practical situations.

The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
