Description
TECHNICAL FIELD
[0001] The utility model relates to the field of inflatable product production, especially a welding die. BACKGROUND
[0002] Many existing inflatable products (such as inflatable beds) are maintained by a pull belt when the inflatable product is inflated. The pull belt used in many inflatable products is a wire pull belt, which includes two pressing strips and a plurality of parallel wire bodies connected to the two pressing strips at both ends. At present, when the inflatable product using the wire pull belt is manufactured, a wire pull belt group (including a plurality of parallel wire bodies and a plurality of pressing strips combined with the wire bodies) is generally directly produced, and then the wire pull belt group is slitting (cutting the pressing strips) to obtain the wire pull belt. The wire pull belt obtained by slitting is welded by a welding device to simultaneously melt the two pressing strips of the wire pull belt and the upper and lower sheets. In the production of the wire pull belt group, the plurality of wire bodies are generally conveyed in parallel, the pressing strips are placed on each wire body by a pressing strip conveying device, and then the pressing strips are heated by the welding die of the welding device to bond the pressing strips and each wire body. This method is prone to displacement of the position of the pressing strips placed on the wire bodies, resulting in unqualified wire pull belt groups.
[0003] In view of the above problems, it is necessary to study a welding die that can accurately connect the pressing strips and the wire bodies. SUMMARY
[0004] The utility model aims at providing a welding die that can accurately connect the pressing strips and the wire bodies.
[0005] In order to achieve the above purpose, the solution of the utility model is as follows:
[0006] A welding die includes a die body, the die body is provided with a suction channel and a heating surface, and the heating surface is provided with a plurality of suction holes communicating with the suction channel.
[0007] The heating surface of the die body is provided with a pattern.
[0008] Each suction hole of the die body is distributed in at least one row on the heating surface.
[0009] The suction hole is communicated with the suction channel through a connecting channel, and the aperture of the connecting channel is smaller than the aperture of the suction hole.
[0010] The die body is provided with a plurality of material reducing holes.
[0011] With the above scheme, the welding die of the utility model has the suction capacity, so when the welding die of the utility model needs to connect the pressing strip and the wire body, the welding die of the utility model can first adsorb the pressing strip, ensures that the position of the pressing strip and the welding die is relatively stable, then moves the welding die, so that the pressing strip contacts the multiple wire bodies, finally the welding die heats the pressing strip again, so that the pressing strip is bonded with each wire body.
[0012] From the above, the welding die of the utility model can adsorb the pressing strip, ensures that the position of the pressing strip and the welding die is relatively stable, thereby ensuring that the subsequent pressing strip and the wire body are accurately connected.

[0017] In order to further explain the technical scheme of the utility model, the utility model is described in detail below through specific embodiments.
[0018] As shown in Figures 1 to 4 The utility model discloses a kind of welding die body 1, it includes die body 1 body, die body 1 body is equipped with suction passage 11 and heating surface 12, heating surface 12 is equipped with multiple adsorption hole 13 with suction passage 11, suction passage 11.
[0019] The welding die body 1 of the utility model is provided with a suction passage 11 and a plurality of suction holes 13 communicated with the suction passage 11, the suction holes 13 are located on the heating surface 12, and the suction passage 11 is used for connecting a gas pump; in this way, the welding die body 1 of the utility model can have the adsorption capacity, so that when the welding die body 1 of the utility model needs to connect the pressing strip and the wire body, the welding die body 1 of the utility model can first adsorb the pressing strip, the position of the pressing strip and the welding die body 1 is relatively stable, then the welding die body 1 is moved, the pressing strip contacts the plurality of wire bodies, finally the welding die body 1 heats the pressing strip, and the pressing strip is bonded with the wire bodies. As can be seen from the foregoing, the welding die body 1 of the utility model can adsorb the pressing strip, the position of the pressing strip and the welding die body 1 is relatively stable, thereby ensuring that the pressing strip and the wire body are accurately connected subsequently. It should be noted that when the welding die body 1 of the utility model is used, the wire body can be arranged between the welding die body 1 and the sheet body (an upper sheet or a lower sheet), so that when the welding die body 1 heats the pressing strip to bond the pressing strip with the wire bodies, the pressing strip is also fused with the sheet body.
[0020] In the embodiment of the utility model, each suction hole 13 of the die body 1 body is distributed in at least one row on the heating surface 12 along the length direction of the die body 1 body, so that when the welding die body 1 of the utility model adsorbs the pressing strip, the welding die body 1 has a plurality of adsorption positions for the pressing strip along the length direction of the pressing strip, thereby ensuring that the welding die body 1 of the utility model stably adsorbs the pressing strip. The suction hole 13 can be communicated with the suction passage 11 through the connecting passage 14, the aperture of the connecting passage 14 is smaller than the aperture of the suction hole 13, and the connecting passage 14 can enhance the gas flow rate effect and improve the adsorption force of the suction hole 13.
[0021] In the embodiment of the utility model, the die body 1 body is provided with a plurality of material reducing holes 15, and the material reducing holes 15 can reduce the weight and material cost of the die body 1.
[0022] In the embodiment of the utility model, the heating surface 12 of the die body 1 body can be provided with a pattern, so that after the pressing strip is fused with the sheet body, the fusion part of the pressing strip and the sheet body can directly form a pattern, thereby improving the appearance of the product.
