[0002] The spring layer of a spring mattress is adhesively fixed by a number of independent pocket springs; such independent pocket springs are formed by inserting single springs into cloth bags, each cloth bag being independently wrapped, and then these cloth bags being adhesively bonded side by side to form the spring layer of the spring mattress. In the prior art, hot melt adhesive is often used to adhesively fix the spring ends to the cloth bags and adjacent cloth bags.

[0003] During the production of the spring layer of a spring mattress, a screw extruder can be used to melt hot melt adhesive particles into liquid hot melt adhesive for adhesively bonding the cloth bags and springs in the spring layer.

Detailed implementation manners

[0032] The following further describes the present application in detail with reference to the Figures 1 - 3 accompanying drawings.

[0033] An embodiment of the present application discloses a temperature reduction mechanism for a material barrel. Referring to Figure 1 and Figure 2 , the material barrel 1 is provided with a first accommodating cavity 13 for accommodating materials. The material barrel 1 is provided with a feed inlet 11 and a discharge outlet 12, and the discharge outlet 12 of the material barrel 1 is communicated with a screw extruder.

[0034] Referring to Figure 1 and Figure 2 , along the direction away from the discharge outlet 12 of the material barrel 1, the temperature reduction mechanism of the material barrel 1 sequentially includes a heat dissipation component 2, a heat-conducting colloid 3 and a water-cooling component 4; the heat dissipation component 2, the heat-conducting colloid 3 and the water-cooling component 4 are all fixedly arranged on the outer periphery of the material barrel 1.

[0035] Referring to Figures 1 to 3 , the heat dissipation component 2 includes a substrate 21, fins 22 and a double-sided heat-conducting tape 23; a plurality of fins 22 are provided, and the plurality of fins 22 are fixedly arranged on the substrate 21 at intervals, and the plurality of fins 22 are arranged in a circle. The double-sided heat-conducting tape 23 is bonded to the side of the substrate 21 away from the fins 22, and the double-sided heat-conducting tape 23 is fixedly bonded to the outer periphery of the material barrel 1.

[0036] The double-sided heat-conducting tape 23 can be composed of an acrylic polymer filled with heat-conducting ceramic powder and compounded with an organic silicone adhesive. Thus, the double-sided heat-conducting tape 23 has the characteristics of high heat conduction and insulation, can be closely and firmly attached to the material barrel 1 and the substrate 21, and quickly conducts the heat on the side wall of the material barrel 1 to the fins 22, so as to dissipate the heat into the external air.

[0037] Referring to Figures 1 to 3 , the heat dissipation component 2 is arranged on one side of the material barrel 1 close to the discharge outlet 12, so that the heat dissipation component 2 has a heat dissipation and temperature reduction effect on the side wall of the material barrel 1 and the internal space of the material barrel 1; when the heat of the screw extruder is transferred to the material barrel 1, the heat dissipation component 2 can dissipate this part of the heat, so as to reduce the temperature in the material barrel 1, reduce the movement of heat in the direction of the discharge outlet 12 of the material barrel 1, and reduce the melting and agglomeration of hot melt adhesive particles, so as to facilitate the dropping of hot melt adhesive particles into the screw extruder.

[0038] Reference Figure 1 Figure 1 , the temperature reduction mechanism further includes a fixing component 5 for fixedly connecting the heat dissipation component 2 and the barrel 1. In this embodiment, the fixing component 5 includes a fastening bolt 51 and a fastening nut 52; there are two heat dissipation components 2, which are arranged oppositely, and the two heat dissipation components 2 are sleeved on the outer periphery of the barrel 1. Connection ear plates 211 are provided at both ends of the substrate 21, and fixing holes for the fastening bolts 51 to pass through are formed in the connection ear plates 211. The fastening bolts 51 are threadedly connected with the fastening nuts 52 to force the two heat dissipation components 2 to clamp the barrel 1. That is, the fixing component 5 is used to clamp the heat dissipation component 2 and the barrel 1, so as to improve the fitting degree between the heat dissipation component 2 and the barrel 1, facilitating heat conduction. At the same time, the fixing component 5 also further improves the connection strength between the heat dissipation component 2 and the barrel 1, improving the stability of the operation of the temperature reduction mechanism.

[0039] Reference Figures 1 to 2 Figures 1 to 2 , the water-cooling component 4 is arranged on the side of the heat dissipation component 2 away from the discharge port 12 of the barrel 1. The water-cooling component 4 includes a water-cooling box 41, a water-cooling pipe 42 and a heat-insulating layer 43. The water-cooling box 41 is sleeved on the outer periphery of the barrel 1, and a second accommodation cavity 413 for accommodating water is provided in the water-cooling box 41; in this embodiment, the outer steel plate of the water-cooling box 41 is welded and fixed to the barrel 1; a water inlet pipe 411 is provided on the side of the water-cooling box 41 close to the feed port 11 of the barrel 1, and a water outlet pipe 412 is provided on the side of the water-cooling box 41 close to the discharge port 12 of the barrel 1. Under normal conditions, both the water inlet pipe 411 and the water outlet pipe 412 are sealed.

[0040] Reference Figures 1 to 2 Figures 1 to 2 , the water-cooling pipe 42 is fixedly arranged in the second accommodation cavity 413, and both ends of the water-cooling pipe 42 are externally connected to a water-cooling device. The water-cooling pipe 42 is used for the circulation of cooling water; thus, the cooling water in the water-cooling pipe 42 is used to cool the water in the water-cooling box 41, improving the temperature reduction effect of the water-cooling component 4 on the barrel 1.

[0041] Reference Figures 1 to 2 Figures 1 to 2 , the heat-insulating layer 43 is arranged on the outer periphery of the water-cooling box 41 to maintain the temperature inside the water-cooling box 41. Thus, the heat-insulating layer 43 is used to keep a relatively low temperature inside the water-cooling box 41, improving the temperature reduction effect of the water-cooling component 4 on the barrel 1, reducing the melting and bonding of the hot melt adhesive particles at the top of the barrel 1, and facilitating the dropping of the hot melt adhesive particles into the screw extruder. The staff can brush a heat-insulating coating on the outer periphery of the water-cooling box 41 to form the heat-insulating layer 43.

[0042] Reference Figures 1 to 2, there is no extrusion of other hot melt adhesive particles on the upper part of the hot melt adhesive particles in the area of the material barrel 1 near the discharge port 12, and the temperature in this area is relatively low. After the hot melt adhesive particles in this area are melted, they are more likely to bond into blocks, making it difficult for the hot melt adhesive particles to fall. Therefore, in this embodiment, a water cooling component 4 is provided at the discharge port 12 of the material barrel 1 to cool the material barrel 1 and reduce the occurrence of the hot melt adhesive particles in this area being heated and melted.

[0043] Refer to Figures 1 to 3 , the heat-conducting colloid 3 is fixedly arranged on the outer periphery of the material barrel 1. The heat-conducting colloid 3 is arranged between the heat dissipation component 2 and the water cooling component 4, and the heat-conducting colloid 3 is in contact with the substrate 21 and the fins 22 of the heat dissipation component 2, and the water cooling box 41 of the water cooling component 4. After the staff installs the heat dissipation component 2 and the water cooling component 4, the staff fills heat-conducting glue between the water cooling component 4 and the heat dissipation component 2, and makes part of the heat-conducting glue embed into the gap between adjacent fins 22; after the heat-conducting glue solidifies and hardens, the heat-conducting colloid 3 is formed. Utilizing the temperature difference between the heat dissipation component 2 and the water cooling component 4, the heat-conducting colloid 3 can conduct the heat on the heat dissipation component 2 to the water cooling component 4, thereby further improving the heat dissipation efficiency of the heat dissipation component 2. The temperature of the area of the material barrel 1 near the discharge port 12 can be reduced, and the melting of the hot melt adhesive particles in the material barrel 1 can be reduced.

[0044] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
