Description

A multi-directional adhesive spraying and uniform application device for mattress production Technical Field

[0001] This utility model relates to the field of adhesive spraying equipment technology, and in particular to a multi-directional adhesive spraying and uniform application equipment for mattress production. Background Technology

[0002] The primary function of a mattress is to provide a comfortable sleeping environment, supporting and protecting the body, reducing pressure points, and thus improving sleep quality. We know that mattress support is mainly achieved through its internal fillings, which come in many varieties, such as springs, foam, and latex. To improve the mattress's appearance, durability, and feel, the fillings and the fabric need to be secured together. Common methods of securing these materials include stitching and the use of adhesives. Support is fundamental to a mattress. To achieve sufficient support, multiple layers of materials need to be layered and combined, such as the outer fabric, various lining materials, and springs. Adhesives are responsible for firmly bonding these materials. Currently, the adhesives used in mattresses are broadly classified into two types: water-based adhesives and hot melt adhesives. These two adhesive methods are widely used in our daily lives to bond various foams, non-woven fabrics, pillowcases, and other standard cushioning materials used in mattress and furniture cushion manufacturing. Water-based adhesives are environmentally friendly adhesives made by using natural or synthetic polymers as binders and water as a solvent or dispersant, replacing toxic organic solvents that pollute the environment.

[0003] In mattress manufacturing, the adhesive spraying process is a crucial step, used to bond the various layers of materials together. Currently, existing mattress adhesive spraying equipment has some shortcomings. Traditional equipment typically only sprays adhesive in a single direction and location, producing adhesive residue that is generally parallel stripes. This makes it difficult to achieve uniform application across multiple areas, potentially leading to uneven bonding between the mattress layers. This can affect the mattress's quality and lifespan, indicating room for improvement. Summary of the Invention

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a multi-directional adhesive spraying and uniform application device for mattress production, thereby solving the above-mentioned problem.

[0005] To achieve the above objectives, a multi-directional adhesive spraying and uniform application device for mattress production is provided, comprising a workbench, with door frames fixedly connected to both ends of the workbench. A housing is fixedly connected to the workbench via the two door frames. A negative pressure cover is provided in the upper center of the housing. A slide is provided inside the housing. Slide rods are slidably connected to both ends of the slide. The two ends of the two slide rods are respectively fixedly connected to the upper sides of the corresponding door frames. A lead screw nut is fixedly connected to the upper center of the slide. A transmission screw is driven to the upper part of the slide via the lead screw nut. A transmission sprocket is fixedly sleeved on the outer side of one end of the transmission screw. A drive motor is fixedly connected to the upper center of the housing near the transmission sprocket. A transmission chain is provided at the output end of the drive motor.

[0006] Both sides of the slide are slidably connected to glue spraying bases, and a fixed support is provided on one side of the box. A glue spraying guide plate is fixedly connected above the fixed support.

[0007] According to the multi-directional glue spraying and uniform application equipment for mattress production, the glue spraying base includes a base body, a slider, glue sprayers, guide wheels, and return springs. A slider is fixedly connected to the top of the base body, and the base body is slidably connected to the interior of the slide block through the slider. Multiple glue sprayers are equidistantly arranged at the bottom of the base body. A guide wheel is rotatably connected to the middle of the end of the slider near the glue spraying guide plate, and return springs are provided on both sides of the end of the slider away from the glue spraying guide plate.

[0008] According to the multi-directional adhesive spraying and uniform application equipment for mattress production, a negative pressure pipe is fixedly connected to the upper center of the negative pressure cover, and an exhaust gas purifier is connected through the negative pressure pipe.

[0009] According to the multi-directional adhesive spraying and uniform application equipment for mattress production, the output end of the drive motor is fixedly fitted with a drive sprocket, the drive sprocket is connected to the drive sprocket through a transmission chain, and a baffle cover is provided on the outside of the transmission chain.

[0010] According to the multi-directional adhesive spraying and uniform application equipment for mattress production, the two ends of the transmission screw are respectively rotatably connected to the corresponding gantry, and the transmission screw passes through the screw nut and cooperates with the screw nut.

[0011] According to the multi-directional adhesive spraying and uniform application equipment for mattress production, the bottom of the fixed support is fixedly connected to the workbench, and the box body has strip holes corresponding to the adhesive spraying guide plate.

[0012] According to the multi-directional adhesive spraying and uniform application equipment for mattress production, the adhesive spraying guide plate is provided with corrugated teeth on the side near the adhesive spraying seat, and the position spacing of the guide wheels of the two adhesive spraying seats corresponds to the position spacing of the crests and troughs of the corrugated teeth.

[0013] According to the multi-directional glue spraying and uniform application equipment for mattress production, the positional distance between the glue sprayers below the two glue spraying seats corresponds to the amplitude distance of the corrugated teeth, and the glue sprayers of the two glue spraying seats are arranged in a relatively staggered manner.

[0014] The above solution has at least one of the following beneficial effects:

[0015] 1. The present invention has two independently laterally sliding glue spraying bases under the slide base. With the glue spraying guide plate with corrugated teeth, the glue sprayer under the glue spraying base can be laterally displaced by the corrugated teeth and return spring when the slide base moves. This makes the glue application path interlaced, which is convenient for the glue to be applied evenly, reduces the problem of uneven bonding, and enhances the practicality of the device.

[0016] 2. The distance between the guide wheels of the two glue spraying seats in this utility model corresponds to the distance between the crests and troughs of the corrugated teeth. When the slide moves, the two glue spraying seats can simultaneously rise and fall along the crests and troughs, balancing the influence of the spring force of the return springs of the two glue spraying seats and the reaction force between the corrugated teeth on the transmission screw. This can stabilize the motor load, extend the service life of the motor, and enhance the practicality of the device.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0025] This section will describe in detail the specific embodiments of the present utility model. Preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present utility model. The drawings are all in a very simplified form and use non-precise proportions. They are only used to help to explain the embodiments of the present utility model in a convenient and clear way, and should not be construed as limiting the scope of protection of the present utility model.

[0026] Referring to Figures 1-4, this utility model embodiment provides a multi-directional adhesive spraying and uniform coating device for mattress production, including a workbench 1, with door frames 2 fixedly connected to both ends of the upper part of the workbench 1, and a box body 3 fixedly connected to the workbench 1 through the two door frames 2. A negative pressure cover 4 is provided in the upper middle part of the box body 3, and a negative pressure pipe is fixedly connected to the upper middle part of the negative pressure cover 4, and an exhaust gas purifier is connected through the negative pressure pipe to absorb harmful gases volatilized from the adhesive.

[0027] The interior of the housing 3 is equipped with a slide 6. Both ends of the slide 6 are slidably connected to slide rods 5. Both ends of the two slide rods 5 are fixedly connected to the upper sides of the corresponding gantry 2. A screw nut 7 is fixedly connected to the upper middle of the slide 6. A transmission screw 8 is connected to the upper part of the slide 6 through the screw nut 7. Both ends of the transmission screw 8 are rotatably connected to the corresponding gantry 2. The transmission screw 8 passes through the screw nut 7 and engages with the screw nut 7. A transmission sprocket 10 is fixedly sleeved on the outer side of one end of the transmission screw 8. A drive motor 11 is fixedly connected to the middle of the upper part of the housing 3 near the transmission sprocket 10. A transmission chain 12 is provided at the output end of the drive motor 11. A drive sprocket is fixedly sleeved at the output end of the drive motor 11. The drive sprocket is connected to the transmission sprocket 10 through the transmission chain 12. A baffle cover is provided on the outer side of the transmission chain 12. The slide 6 can be driven to reciprocate along the direction of the slide rods 5 by the forward and reverse rotation of the drive motor 11.

[0028] Both sides of the slide block 6 are slidably connected to glue spraying bases 9. A fixed support 13 is provided on one side of the housing 3. The bottom of the fixed support 13 is fixedly connected to the workbench 1. A glue spraying guide plate 14 is fixedly connected to the top of the fixed support 13. The housing 3 has slots corresponding to the glue spraying guide plate 14. The glue spraying base 9 includes a base 91, a slider 92, a glue sprayer 93, a guide wheel 94, and a return spring 95. The slider 92 is fixedly connected to the top of the base 91. The base 91 is slidably connected to the interior of the slide block 6 through the slider 92. Multiple glue sprayers 93 are equidistantly arranged at the bottom of the base 91. The middle of the end of the slider 92 near the glue spraying guide plate 14 is rotatably connected to the guide wheel 94. Return springs 95 are provided on both sides of the end of the slider 92 away from the glue spraying guide plate 14. The two independently slidable glue spraying bases 9 under the slide block 6, together with the corrugated glue spraying guide plate 14, allow the glue spraying base 9 to slide horizontally. When the slide block 6 moves, the glue sprayer 93 is subjected to the action of the corrugated teeth and the return spring 95, which produces an orientation change that is the same as the shape of the corrugated teeth. This causes the glue application paths to be staggered, which facilitates uniform glue application and reduces uneven adhesion. The glue spraying guide plate 14 is provided with corrugated teeth on the side near the glue spraying base 9, and the position spacing of the guide wheels 94 of the two glue spraying bases 9 corresponds to the position spacing of the crests and troughs of the corrugated teeth. When the slide block 6 moves, the two glue spraying bases 9 can be in the rising and falling state along the crests and troughs of the corrugated teeth, respectively. This balances the effect of the return springs 95 of the two glue spraying bases 9 on the transmission screw 8 due to the elastic force between the spring force and the corrugated teeth, which can stabilize the motor load and extend the service life of the motor. The position spacing of the glue sprayers 93 below the two glue spraying bases 9 corresponds to the amplitude spacing of the corrugated teeth, and the glue sprayers 93 of the two glue spraying bases 9 are arranged in a relatively staggered manner.

[0029] Working Principle: During operation, the two independently sliding glue spraying seats 9 under the slide 6, together with the corrugated glue spraying guide plate 14, allow the glue sprayer 93 below the glue spraying seat 9 to undergo positional changes in the same shape as the corrugated teeth as the slide 6 moves. This results in the glue spraying lines being staggered, facilitating even glue application and reducing uneven adhesion. Simultaneously, the distance between the guide wheels 94 of the two glue spraying seats 9 corresponds to the distance between the crests and troughs of the corrugated teeth. This allows the two glue spraying seats 9 to be in rising and falling states along the crests and troughs of the corrugated teeth as the slide 6 moves. This balances the effect of the return springs 95 of the two glue spraying seats 9 on the transmission screw 8 due to the reaction force between the spring force and the corrugated teeth, thus stabilizing the motor load and extending the motor's service life.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
