Description

Technical Field

[0001] The utility model relates to the technical field of mattress production, in particular to a mattress hot melt adhesive machine. Background Art

[0002] Hot melt glue machine is mainly used for automatic application equipment of hot melt glue spraying, scraping, rolling, coating and injection. It is widely used in household goods, automobile industry and book binding industry, especially in the production of household goods, such as mattress production, in order to fit the wear point with the fabric, hot melt glue machine is often used to inject glue to make the fabric fit the outer surface of the mattress fully. With the advancement of modern technology, the number of hot melt glue machines has gradually increased, making it more convenient to use.

[0003] In response to this, China Patent No. CN214717745U proposed a mattress hot melt glue machine, which automatically and accurately sprays glue during the transportation of mattresses and fabrics, and can achieve fabric bonding at the back end, thereby achieving the effect of accurate glue spraying, solving the problem of inaccurate glue spraying of existing devices;

[0004] However, in the process of spraying glue to stick the mattress and fabric, the above technical scheme can only spray glue on the surface of the mattress and wait for the fabric to overlap and stick with it. However, after spraying with the glue gun, the glue is accumulated, and some areas are accumulated with more glue, while other areas have no glue. When the fabric is squeezed later to make it stick to the surface of the mattress, although the glue can be forced to flow, the glue is unevenly distributed among the fabric and the mattress. Long-term use can easily cause some areas of the fabric to fall off from the mattress. Over time, the friction during sleep causes all of the fabric to fall off, reducing the service life of the mattress. In this regard, a mattress hot melt adhesive machine is proposed in this design scheme. Utility Model Content

[0022] In order to more clearly illustrate the overall concept of the utility model, a detailed description is given below in the form of examples in conjunction with the accompanying drawings.

[0023] The examples are as follows:

[0024] The utility model provides Figure 1-4 The mattress hot melt adhesive machine shown comprises a support base 1 and a glue spraying mechanism 2 and a limiting mechanism 7 respectively installed above and on both sides of the support base 1;

[0025] The glue spraying mechanism 2 includes a mounting frame 201 fixed on the top of the supporting base 1, three limiting slide grooves 202 are opened on the top of the mounting frame 201, and a slider 203 is slidably provided on the inner wall of the three limiting slide grooves 202, and a glue dispensing base 204 is fixedly provided at the bottom of the slider 203, and a plurality of glue guns 205 are installed at equal distances on one side of the bottom of the glue dispensing base 204, and glue injection tubes 206 are inserted on both sides of the top of the glue dispensing base 204, and the inner walls of the two glue injection tubes 206 are respectively connected to the inner walls of the plurality of glue guns 205, and a fixing frame is fixedly provided at both ends of one side of the glue dispensing base 204. 207, one end of the two fixed frames 207 is rotatably provided with a movable frame 208, a rubber roller 209 is rotatably provided between the two movable frames 208, the bottom of the two fixed frames 207 is rotatably provided with an electric telescopic rod 210, and the output ends of the two electric telescopic rods 210 are rotatably connected to the bottoms of the two movable frames 208 respectively, and when the rubber roller 209 rolls glue on the surface of the mattress, due to its smooth surface, the glue will not be attached to its surface in large quantities and separate from the mattress, and the limiting slide groove 202 has a limiting effect on the slider 203, so that it will not separate from the mounting frame 201;

[0026] Furthermore, a screw hole 211 is provided on one side of the slider 203, a screw rod 212 is rotatably provided at the middle position of the top of the mounting frame 201, and the outer wall of the screw rod 212 is threadedly connected to the inner wall of the screw hole 211, and one end of the screw rod 212 passes through the outer wall of the mounting frame 201 and is connected to a motor 213. After the motor 213 is started, the screw rod 212 moves left and right with the slider 203 and the glue spraying mechanism 2 at the lower end, and moves at a uniform speed;

[0027] Furthermore, a conveyor belt 3 is installed on the top of the support base 1 below the mounting frame 201 , a through slot 4 is opened on one side of the top of the support base 1 , and a waste glue box 5 is fixedly provided on one side of the bottom of the support base 1 .

[0028] The inner wall of the waste glue box 5 is connected with the inner wall of the through groove 4. A scraper 6 is fixedly provided at the edge of the through groove 4 on the top of the support base 1, and one side of the scraper 6 contacts the surface of the conveyor belt 3. During the glue spraying process, part of the hot melt glue will fall on the surface of the conveyor belt 3. By arranging the scraper 6 on the support base 1 and contacting the conveyor belt 3 at the bottom, the glue on the surface is scraped off and falls into the waste glue box 5 below through the through groove 4 for collection and waiting for processing by the staff, so that too much glue will not be attached to the conveyor belt 3, which will cause the staff to spend a lot of time and energy to clean it later.

[0029] Furthermore, the limiting mechanism 7 includes limiting slots 701 opened at the edges of both sides of the top of the supporting base 1, and the bottoms of the inner walls of the two limiting slots 701 are provided with connecting holes, and the inner walls of the two limiting slots 701 are interspersed with limiting plates 702. The position of the limiting plate 702 is adjusted in the limiting slot 701 according to the width of the mattress, thereby adjusting the limiting width of the limiting mechanism 7.

[0030] A connecting frame 703 is fixedly provided at one end of the two limiting plates 702, and a plurality of guide wheels 704 are rotatably provided on one side of the two connecting frames 703 at equal distances. A connecting groove 705 is provided on the top of the two limiting plates 702, and bolts are threadedly connected to the inner walls of the two connecting holes through the inner walls of the two connecting grooves 705 respectively. When limiting, the limiting mechanism 7 rolls on both sides of the mattress through the guide wheels 704 on one side of the connecting frame 703, and also plays a traction role, so that it will not affect the transmission of the mattress when limiting.

[0031] Working principle: When using the mattress hot melt glue machine in this design, the mattress is transported by the conveyor belt 3 on the supporting base 1. During the transportation, the glue dispensing base 204 is connected to the connected glue bucket through the glue injection tube 206 and the hot melt glue is introduced into the glue dispensing base 204 and sprayed from the glue gun 205 and sprayed on the surface of the mattress. The motor 213 drives the screw rod 212 to rotate and the slider 203 slides back and forth in the limiting slide groove 202 so that the glue gun 205 moves left and right above the mattress to spray glue evenly. At the same time, the electric telescopic rod 210 is started to make the movable frame 208 rotate on the fixed frame 207 so that the glue roller 209 is adjusted up and down until the surface is in contact with the glue gun 205. On the mattress, after the glue gun 205 dispenses glue on the mattress, the mattress is transmitted by the conveyor belt 3 and rolled by the rubber roller 209 to evenly roll the glue on the mattress to make it evenly distributed. When the fabric is glued in the later stage, it is not easy to have areas that cannot be glued, which reduces the probability of the fabric and the mattress being separated, and improves the service life of the mattress. According to the mattresses of different widths, the distance between the limiting plates 702 is adjusted in the limiting card slot 701, and then it is fixed by bolts passing through the connecting slot 705, so that the guide wheels 704 on the connecting frame 703 always contact the two sides of the mattress, limit it, and make it difficult to deviate during transmission, so as to facilitate the upper end spraying mechanism 2 to spray glue evenly on the surface of the mattress.
