Description

Technical Field

[0001] The utility model relates to a novel sponge strip sticking mechanism for a spring bed net, belonging to the technical field of bed net equipment. Background Art

[0002] In mattress production, to ensure that the four sides of the mattress have strong support and do not slip off the edge, and at the same time ensure that the appearance of the mattress side is flat and the user cannot touch the springs, industry practitioners generally add springs with large supporting force around the spring bed net as reinforcement around the perimeter, or use sponge strips with greater hardness and fix them around the spring bed net with glue to strengthen the surrounding support.

[0003] The prior art "Application No.: 2024202326777" discloses a sponge strip sticking device for a spring bed net. The sponge strip is pushed to one side of the bed net for bonding through a sponge strip feeding mechanism and a pushing mechanism, eliminating the need for manual placement of the sponge strip and automatically completing the sponge strip sticking process for the bed net. Specifically, the bed net is conveyed towards the sponge strip feeding mechanism by a feeding roller, and then the sponge strip on the calibration conveyor belt is pushed to the edge of the bed net for bonding by a pushing profile.

[0004] The above prior art has the following defects: 1. To provide a certain moving space for the nozzle to flow out, a certain gap is left between the calibration conveyor belt and the feeding roller. When the pushing profile pushes the sponge strip on the calibration conveyor belt towards the feeding roller, problems such as sponge strip jamming or tilting may occur, affecting the bonding quality; 2. When the pushing profile pushes the sponge strip to the edge of the bed net for bonding, since the bed net does not move, when the sponge strip contacts the bed net, the non-woven fabrics at the upper and lower ends of the bed net edge will be wrinkled, affecting the appearance of the bed net; 3. There is only one spray gun, resulting in low work efficiency.

[0005] Therefore, how to provide a novel sponge strip sticking mechanism for a spring bed net is the research objective of the present utility model. Summary of the Utility Model

[0006] In view of the above deficiencies in the technology, the present utility model provides a novel sponge strip sticking mechanism for a spring bed net. A section of bed net conveyor belt moves the bed net of the feeding roller towards the sponge strip feeding mechanism. When the pushing profile pushes the sponge strip to bond with the bed net, the bed net conveyor belt moves back simultaneously, enabling the sponge strip to move with the bed net and bond to the bed net, avoiding wrinkling the non-woven fabrics at the upper and lower ends of the bed net edge; at the same time, pins are distributed on the pushing profile to support the sponge strip, preventing the sponge strip from falling into the gap between the bed net conveyor belt and the sponge strip conveyor belt and avoiding problems such as sponge strip jamming or tilting; two groups of nozzles are provided to spray glue on the bed net, improving work efficiency.

The bed net conveyor belt 103 is arranged on the lifting base 102, and a lifting motor 105 is provided above the lifting base 102 to drive it to rise or fall. The lifting motor 105 and the screw rod drive the lifting base 102 to rise or fall, thereby driving the bed net conveyor belt 103 to rise or fall, and adjusting the distance between the bed net conveyor belt 103 and the bed net under-conveyor belt 104 to adapt to the use of bed nets of different thicknesses. The bed net under-conveyor belt 104 is arranged on On the fixed base 101, one end thereof is transmission-connected with a bed net conveying motor 106, and the rotating shaft of the conveyor belt 104 under the bed net is transmission-connected with the rotating shaft of the conveyor belt 103 on the bed net via a connecting rod and a bevel gear.

[0035] The sponge strip feeding mechanism 20 includes an upper sponge strip conveyor belt 201 and a lower sponge strip conveyor belt 202 arranged up and down. The upper sponge strip conveyor belt 201 is provided with an upper stopper rod 203 that can be lifted and lowered by a cylinder at one end of the sponge strip conveyor belt 103 close to the bed net.

The spacing between the upper sponge strip conveyor belt 201 and the lower sponge strip conveyor belt 202 is adjusted according to the fixed base 101 and the lifting base 102 so that the thickness of the sponge strip is consistent with the thickness of the bed net. The function of the stopper rod is to support the other end of the sponge strip when the pin 3042 extends out and inserts into the sponge strip so that the sponge strip will not be pushed down by the pin 3042.

[0036] The sponge strip pushing mechanism 30 includes an upper pushing profile 301 and a lower pushing profile 302 arranged one above the other. The upper pushing profile 301 is arranged above the lower pushing profile 302 via a guide rod and a linear bearing and can be lifted and lowered.

[0039] In this embodiment, preferably, the sponge strip upper conveyor belt 201 and the upper mounting profile 401 are arranged on the lifting base 102, and the sponge strip lower conveyor belt 202 and the lower mounting profile 402 are arranged on the fixed base 101. That is, the distance between the sponge strip upper conveyor belt 201 and the sponge strip lower conveyor belt 202, as well as the distance between the upper spray gun 403 and the lower spray gun 404, change with the changes of the bed net upper conveyor belt 103 and the bed net lower conveyor belt 104, so as to adapt to the use of sticking sponge strips on bed nets of different thicknesses.

[0040] In this embodiment, preferably, the upper pushing profile 301 is arranged on the supporting profile of the sponge strip upper conveyor belt 201, the lower pushing profile 302 is arranged on the supporting profile of the sponge strip lower conveyor belt 202, and the upper pushing profile 301 and the lower pushing profile 302 are arranged inside the sponge strip upper conveyor belt 201 and the sponge strip lower conveyor belt 202.

[0041] In this embodiment, preferably, the upper spray gun 403 and the lower spray gun 404 are respectively arranged on the slide rails and sliders of the upper mounting profile 401 and the lower mounting profile 402 through cylinders, and the spray guns are lifted by the cylinders to facilitate the adjustment of the glue spraying position.

[0042] In this embodiment, preferably, through holes for the pins 3042 to pass through are distributed on the upper pushing profile 301 and the lower pushing profile 302.

[0043] When the utility model is in use: One end of the bed net is conveyed to the bed net conveyor belt 10 by the bed net feeding mechanism, and then one end of the bed net is conveyed by the bed net conveyor belt 10 to a position close to the sponge strip feeding mechanism 20 and accurately positioned by a photoelectric induction switch. The upper cloth pressing rod 107 rises to turn up the non-woven fabric on the upper edge of the bed net, and the lower cloth pressing rod 108 descends to turn down the non-woven fabric on the lower edge of the bed net, so as to avoid wrinkling the non-woven fabric on the upper and lower edges of the bed net when the sponge strip is bonded to the bed net. At the same time, the sponge strip enters between the upper sponge strip conveyor belt 201 and the lower sponge strip conveyor belt 202 and is accurately positioned and aligned with the bed net by a photoelectric induction switch. Then, the upper spray gun 403 and the lower spray gun 404 of the glue spraying mechanism 40 start to move and spray glue on the side of the bed net. Then, the upper pushing profile 301 and the lower pushing profile 302 of the sponge strip pushing mechanism 30 extend, and the inserted pins 3042 that extend are inserted into the sponge strip. At this time, the upper material blocking rod 203 and the lower material blocking rod 204 hold the sponge strip so that it is not pushed down by the inserted pins 3042. When the inserted pins 3042 are inserted into the sponge strip, the upper material blocking rod 203 and the lower material blocking rod 204 reset, and the upper pushing profile 301 and the lower pushing profile 302 push the sponge strip to fit with the bed net. During the pushing process, the sponge strip will not fall or tilt into the gap between the bed net conveyor belt 10 and the sponge strip feeding mechanism 20 under the support of the inserted pins 3042. During the bonding process of the sponge strip and the bed net, the bed net conveyor belt 10 conveys the bed net back at the same time, and the conveying speed is less than the pushing speed of the sponge strip. In this way, during the bonding process, the non-woven fabric on the upper and lower edges of the bed net gradually exits from the upper cloth pressing rod 107 and the lower cloth pressing rod 108 and covers the top and bottom of the sponge strip without being wrinkled.

[0044] The utility model moves the bed net of the feeding roller towards the sponge strip feeding mechanism 20 through a section of bed net conveyor belt 10. When the pushing profile pushes the sponge strip to be bonded to the bed net, the bed net conveyor belt 10 moves back at the same time, so that the sponge strip follows the bed net to move and is bonded to the bed net, avoiding wrinkling the non-woven fabric at the upper and lower ends of the bed net edge; and the inserted pins 3042 are distributed on the pushing profile, and the sponge strip is supported by the inserted pins 3042 to avoid the sponge strip falling into the gap between the bed net conveyor belt 10 and the sponge strip conveyor belt, and avoiding problems such as sponge strip jamming or tilting.
