Problems solved by technology

The traditional pocket spring bed net is composed of pocket spring strings neatly bonded side by side. The use of glue to bond the pocket spring strings mainly has the following defects: 1) the bonding between the pocket spring strings The strength is low, and it is easy to cause separation between two adjacent pocket spring strings during use, resulting in poor stability and low service life; 2) It is not environmentally friendly, because the glue contains irritating gases or traces of harmful substances, which will affect Customer experience; 3) The production cost is high. In the actual production process, the amount of glue used is large, and the cost of glue is relatively high. Moreover, when using glue to connect bagged spring strings, it is necessary to reserve a certain area for the bag to stick to. Causes the wrinkle waste of non-woven fabrics and increases the cost of non-woven fabrics; 4) The production efficiency is low. Separation occurs between the spring strings, and the time cost is high; 5) Generally, the production method of manual gluing and bonding is used, and the degree of automation is low

Embodiment 1

[0042] Embodiment 1: A kind of combination method of pocket spring bed net.

[0043] refer to Figure 1 to Figure 6 as well as Figure 11 As shown, a method for combining pocket spring bed nets is to weld the non-woven fabrics of several rows of pocket spring strings before and after by ultrasonic welding or heat welding, which specifically includes the following steps:

[0044] S1. Put the previous set of welding knives 17 from the top of the pocket spring string non-woven fabric bag through hot-melt opening or blowing high-temperature gas to melt the non-woven fabric and open the hole. A vertical through-hole 13 is provided on the top of the bag 11, and then the previous set of welding knives 17 penetrate the vertical through-hole 13 vertically downwards, and go deep into the inside of the individual pocket spring;

[0045]S2. The latter group of welding knives 16 are opened from the rear side arc surface of the rear row of pocket spring strings by hot melting or blowing h...

Embodiment 2

[0051] Embodiment 2: a kind of combination method of pocket spring bed net.

[0052] refer to Figure 7 to Figure 11 As shown, a method for combining pocket spring bed nets is to weld the non-woven fabrics of several rows of pocket spring strings before and after by ultrasonic welding or heat welding, which specifically includes the following steps:

[0053] S1. Put the previous set of welding knives 17 from the top of the pocket spring string non-woven fabric bag through hot-melt opening or blowing high-temperature gas to melt the non-woven fabric and open the hole. A vertical through-hole 13 is provided on the top of the bag 11, and then the previous set of welding knives 17 penetrate the vertical through-hole 13 vertically downwards, and go deep into the inside of the individual pocket spring;

[0054] S2. Connect the non-woven fabric at the connection between the adjacent two pocket spring individuals of the rear row of pocket spring strings to the non-woven fabric of the...

Embodiment 3

[0061] Embodiment 3: A kind of combined structure of pocket spring bed net.

[0062] refer to Figure 1 to Figure 6 As shown, a combined structure of pocket spring bed nets includes several rows of pocket spring strings. Using the combination method provided in Example 1, the non-woven fabric contact points of several rows of neatly arranged parallel pocket spring strings are passed through Ultrasonic welding or heat welding together, wherein the non-woven fabric of the front cylindrical arc surface of the pocket spring string individual of the rear row is in contact with the non-woven fabric of the rear cylindrical arc surface of the pocket spring string individual of the previous row at least Two welding connection points 14, the tops of the welded rows of pocket spring strings are welded with the top cloth 2 by ultrasonic welding or thermal welding, and the bottoms of the welded rows of pocket spring strings are ultrasonically welded or thermally welded There is a bottom c...

Abstract

The invention provides a combination method of pocket spring bed nets, which welds several rows of non-woven fabrics of pocket spring strings before and after by ultrasonic welding or thermal welding, without using glue, which is environmentally friendly and safe, and has high production efficiency. The production cost is low and the degree of automation is high. Two sets of welding knives are used to automatically feed the pocket spring strings during welding. One set penetrates vertically into the individual pocket springs, and one set penetrates horizontally into the individual pocket springs and then advances forward. The combined welding method can realize the fixed-point welding between the individual non-woven fabrics of the front and rear pocket spring strings, which will not cause wrinkle waste of the non-woven fabrics and reduce the cost of the non-woven fabrics. The combination structure of the pocket spring bed net obtained by using the combination method provided by the present invention has high cohesive force between pocket spring strings, good stability, long service life, no glue, and good customer experience.

Description

technical field [0001] The invention relates to the technical field of pocket spring bed net combination, in particular to a pocket spring bed net combination method and a combined structure. Background technique [0002] Pocket springs are formed by wrapping a single spring in a cloth bag, and each pocket spring is connected in turn to form a pocket spring string, and the pocket spring strings are arranged and bonded to form a whole to form a pocket spring bed net. The traditional pocket spring bed net is composed of pocket spring strings neatly bonded side by side. The use of glue to bond the pocket spring strings mainly has the following defects: 1) the bonding between the pocket spring strings The strength is low, and it is easy to cause separation between two adjacent pocket spring strings during use, resulting in poor stability and low service life; 2) It is not environmentally friendly, because the glue contains irritating gases or traces of harmful substances, which ...
