Description

Technical Field

[0001] The utility model relates to the field of wire drawing cloth welding equipment, in particular to an adsorption table for a hemming cloth welding machine. Background Art

[0002] When processing wire drawing cloth products, such as wire drawing cloth surfboards, the main body adopts double-layer wire drawing cloth, and then hemming cloth needs to be welded around the wire drawing cloth. The process of welding the hemming cloth to the periphery of the wire drawing cloth needs to be completed on the operating table of the hemming cloth welding machine.

[0003] When the hemming cloth welding machine is working, first place the main body wire drawing cloth on the operating table, then fold the hemming cloth into a U shape and wrap it around the edge of the wire drawing cloth, and then the heat-sealing and melting welding machine hot-melt welds the hemming cloth to the periphery of the wire drawing cloth. During the hot-melt welding process of the hemming cloth, it is necessary to ensure the stable position of the main body wire drawing cloth on the operating table. Only when the position of the main body wire drawing cloth is stable can it be ensured that the position of the hemming cloth on the wire drawing cloth is stable.

[0004] The main problems existing in the current operating table are as follows: The wire drawing cloth is relatively soft and is prone to movement during the welding process, especially when turning. If the material is not fixed properly, it is easy to shift or wrinkle. Secondly, the edge of the operating table is too thick. When the lower hot air gun of the hot air welding mechanism moves, it will touch the edge of the operating table, and the suction holes can only be opened at a place far from the edge, resulting in the inability to firmly suck the edge of the wire drawing cloth. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is: To overcome the deficiencies of the prior art and provide an adsorption table for a hemming cloth welding machine, so as to solve the technical problem that in the adsorption table of the traditional hemming cloth welding machine, when the edge of the adsorption table adsorbs the wire drawing cloth, the edge of the adsorption table cannot be made thin, resulting in the easy interference between the adsorption table and the welding mechanism.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] Provide an adsorption table for a hemming cloth welding machine, including

[0008] A support table, a negative pressure cavity is opened in the support table, and the negative pressure cavity is connected to a negative pressure device;

[0009] A support surface is formed on the support table, an adsorption area is formed at the edge of the support surface, and a plurality of air suction grooves are opened in the adsorption area, and each air suction groove is communicated with the negative pressure cavity;

[0010] A relief step for avoiding the hot air welding mechanism is formed below the edge of the support table.

[0011] Further, the support table includes

[0012] A frustum, with a negative pressure chamber opened inside the frustum;

[0013] A platen, the lower end of the platen is sealingly connected to the frustum, the platen extends horizontally out of the frustum around its periphery, and an avoidance step is formed between the periphery of the platen and the frustum;

[0014] The adsorption area is located on the platen. The air suction groove includes an air suction guide groove and at least one through hole. The inner end of the air suction guide groove extends above the negative pressure chamber, and each through hole is opened on the platen and located at the inner end of the air suction guide groove. The air suction guide groove communicates with the negative pressure chamber through each through hole, and the outer end of the air suction guide groove is close to the edge of the platen.

[0015] Further, a hole plate is sealingly arranged on the adsorption area of the platen, and an adsorption long hole is opened in the hole plate. The adsorption long hole forms the air suction guide groove with the platen.

[0016] Further, an avoidance hole for avoiding the air nozzle on the surfboard is opened on the support platform.

[0017] Further, the air suction guide groove is a straight groove, and each air suction guide groove is arranged side by side.

[0018] The beneficial effects of the present utility model are:

[0019] The present utility model provides an adsorption table for a hemming cloth welding machine. While an air suction groove is opened at the edge of the support platform, an avoidance step is also provided below the support platform. Thus, when the hot melting mechanism of the welding machine welds the wire drawing cloth on the adsorption table, the edge of the adsorption table can adsorb and fix the wire drawing cloth, and at the same time, the avoidance step below the adsorption table will not interfere with the movement of the hot melting mechanism, enabling the adsorption table to stably fix the wire drawing cloth and enabling the welding machine to weld the hemming cloth around it.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] This application provides a suction table for a edge cloth welding machine, which will be described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of this application. And in the following embodiments, each embodiment is described with emphasis. For parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0033] To solve the technical problem in the prior art that after an adsorption groove is opened at the edge of the suction table, the edge cannot be made thin, resulting in easy interference between the suction table and the welding mechanism, an embodiment of this application provides a suction table for a edge cloth welding machine. The following will be elaborated in detail.

[0034] As Figures 1 to 5 shown, a suction table for a edge cloth welding machine includes

[0035] A support table, a negative pressure chamber 11 is opened in the support table, and the negative pressure chamber 11 is connected to a negative pressure device;

[0036] A support surface is formed on the support table, an adsorption area is formed at the edge of the support surface, and a plurality of air suction grooves are opened in the adsorption area, and each air suction groove is communicated with the negative pressure chamber 11;

[0037] An avoidance step 4 for avoiding the hot air welding mechanism is formed below the edge of the support table.

[0038] Specifically, if there is no avoidance step 4, the lower hot air gun in the hot air welding mechanism will touch the support table, affecting the circumferential movement of the hot air welding mechanism around the support table. Now, the existence of the avoidance step 4 enables the hot air welding mechanism to maintain a distance from the support table when welding the edge cloth, enabling the hot air welding mechanism to weld stably.

[0039] In this embodiment, the adsorption area is an annular area surrounding the support platform, and the shape of the support platform is adapted to the shape of the specific wire drawing cloth product.

[0040] In this embodiment, the support platform is used to process the wire drawing cloth surfboard. Therefore, the shape of the support platform in the figure is adapted to the shape of the surfboard.

[0041] Specifically, as an alternative implementation in this embodiment, as Figures 1 to 5 shown, the support platform includes

[0042] a platform body 1, and a negative pressure cavity 11 is formed inside the platform body 1;

[0043] a platform plate 2, the lower end of the platform plate 2 is hermetically connected to the platform body 1, the platform plate 2 extends horizontally out of the platform body 1 around its periphery, and an avoidance step 4 is formed between the periphery of the platform plate 2 and the platform body 1;

[0044] The adsorption area is located on the platform plate 2. The air suction groove includes an air suction guide groove 31 and at least one through hole 21. The inner end of the air suction guide groove 31 extends above the negative pressure cavity 11. Each through hole 21 is formed on the platform plate 2 and is located at the inner end of the air suction guide groove 31. The air suction guide groove 31 communicates with the negative pressure cavity 11 through each through hole 21, and the outer end of the air suction guide groove 31 is close to the edge of the platform plate 2.

[0045] In this embodiment, the platform plate 2 and the platform body 1 are fastened by welding or locking screws. To ensure the sealing performance between them, a sealing strip can be provided.

[0046] In this embodiment, the air suction guide groove 31 can be directly formed on the platform plate 2. The air suction guide groove 31 is directly milled on the platform plate 2 with a drill bit, and then the through holes 21 are drilled in the air suction guide groove 31. Both the air suction guide groove 31 and the through holes 21 are provided on the platform plate 2.

[0047] Specifically, as an alternative implementation in this embodiment, a hole plate 3 is hermetically arranged on the adsorption area of the platform plate 2, and an adsorption long hole is formed inside the hole plate 3. The adsorption long hole forms the air suction guide groove 31 with the platform plate 2.

[0048] The hole plate 3 is hermetically attached to the platform plate 2, so as to ensure that the hole plate 3 can stably adsorb the wire drawing cloth above.

[0049] In this embodiment, the air suction guide groove 31 is formed on the platform plate 2 by connecting the hole plate 3 with the adsorption long hole to the platform plate 2. This method has a relatively low processing cost. The adsorption long hole on the hole plate 3 can be directly formed by stamping. At the same time, only through holes 21 need to be formed at predetermined positions on the platform plate 2, and finally the hole plate 3 is welded. This method does not require milling the air suction guide groove 31 on the platform plate 2, and the efficiency of processing the air suction guide groove 31 on the support platform is higher.

[0050] In this embodiment, the number of orifice plates 3 is multiple, and the respective orifice plates 3 enclose an elliptical annular structure, and the elliptical annular structure corresponds to the shape of the surfboard.

[0051] In this embodiment, an avoidance hole 5 for avoiding the air nozzle on the surfboard is formed on the support table. When manufacturing the surfboard, it is necessary to install the air nozzle on the wire drawing cloth in advance. Now, the avoidance hole 5 is formed on the support table, so that the wire drawing cloth can be kept flat when placed on the support table.

[0052] In this embodiment, the air suction guide groove 31 is a straight groove, and the respective air suction guide grooves 31 are arranged side by side. As Figure 4 shown, the respective air suction guide grooves 31 are radially distributed from the inside to the outside. Through the length of the air suction guide groove 31, the adsorption area for the wire drawing cloth can be extended, so that the wire drawing cloth is stably adsorbed on the support table.

[0053] The negative pressure cavity 11 is in an annular structure within the table body 1. The area of the negative pressure cavity 11 corresponds to the area where the respective through holes 21 are formed on the table board 2. The annularly distributed negative pressure cavity 11 is connected to an air outlet channel, and the air outlet channel is connected to a negative pressure pump. The negative pressure cavity 11 is formed by drilling and milling on the table body 1, and the processing is relatively convenient.

[0054] For the adsorption table of the edge cloth welding machine of the present utility model, the edge of the support table is made thin, and the space below it is vacated as an avoidance step 4, so that the support table will not interfere with the lower hot air gun of the welding mechanism. The thickness of the edge of the support table is about 4 mm, the thickness of the table board 2 is about 2 mm, and the thickness of the orifice plate 3 is about 2 mm. At the same time, the air suction groove is composed of the through hole 21 and the air suction guide groove 31. Even if the edge of the support table is very thin, such a wind guide groove structure can still be provided with an upper wind guide groove to realize the stable adsorption of the wire drawing cloth.
