Description

Technical Field

[0001] This utility model relates to the field of sofa production technology, specifically to a sofa production adhesive spraying equipment. Background Technology

[0002] Glue spraying equipment is used in the sofa production process to evenly spray glue onto different parts of the sofa (such as sponge, fabric, wooden frame, etc.). This equipment helps manufacturers achieve efficient and precise bonding during the production process, ensuring the stability of the sofa structure.

[0003] Traditional handheld glue sprayers are inefficient because the nozzles can become clogged and the entire device may need to be stopped for maintenance.

[0004] Secondly, it is difficult to adapt to different sofa parts (especially areas with curves or recesses).

[0005] Finally, they cannot adapt to different spraying postures, such as horizontal or vertical, and must move sofas or bend over and twist to operate, which is inefficient and can easily cause fatigue or occupational injury. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1:

[0031] Please see Figures 1-5A sofa manufacturing adhesive spraying device includes a main body 1, a replacement mechanism, and a control mechanism. The replacement mechanism includes a nozzle 2, a mounting sleeve 3, an external connector 4, and a cover 5. The nozzle 2 is mounted on the external connector 4, the mounting sleeve 3 is mounted on the external connector 4 and rotatably connected to the cover 5, the external connector 4 is fixedly mounted on the main body 1, and the cover 5 is mounted on the mounting sleeve 3 and cooperates with the nozzle 2. The control mechanism includes a sliding frame 6, rollers 7, a rotating frame 8, an auxiliary wheel 9, and a fixing component. The sliding frame 6 is mounted on the main body 1 and slidably connected to the main body 1, the rollers 7 are mounted on the sliding frame 6 and rotatably connected to the sliding frame 6, the rotating frame 8 is mounted on the sliding frame 6 and rotatably connected to the sliding frame 6, and the auxiliary wheel 9 is mounted on one end of the rotating frame 8 and rotatably connected to the rotating frame 8.

[0032] In this embodiment, the replacement mechanism includes a nozzle 2, a mounting sleeve 3, an external connector 4, and a cover clamp 5. In use, different nozzles 2 are first replaced according to different spraying operations. At this time, the nozzle 2 can be installed on the external connector 4. The sealing gasket 24 on the nozzle 2 is connected with the sealing groove 26 on the external connector 4. After the nozzle 2 enters the cover clamp 5, the cover clamp 5 is rotated so that the first locking block 25 on the nozzle 2 can be connected with the first locking hole 27 on the cover clamp 5. At the same time, the mounting sleeve 3 can be rotated so that the internal thread 23 on the mounting sleeve 3 is engaged with the external thread 22 on the external connector 4, thereby pulling the cover clamp 5 closer to the main body 1. During this process, the first locking hole 27 in the cover clamp 5 is directly engaged with the first locking block 25 on the nozzle 2, thereby fixing the nozzle 2 on the main body 1.

[0033] In this embodiment, the control mechanism includes a sliding frame 6, rollers 7, a rotating frame 8, auxiliary wheels 9, and a fixing component. During use, for woods or paints sensitive to adhesives, careful application of the adhesive is necessary. The distance between the nozzle 2 and the sofa needs to be carefully controlled. First, the rotating frame can be adjusted to a suitable position. Then, the second locking block 29 in the sliding frame 6 can be pulled, causing it to compress the second spring 30 and disengage from the second locking hole 28 on the main body 1. This pushes the sliding frame 6 mounted on the main body 1, causing the sliding frame 6 and rollers 7 to slide in the sliding groove 15. Simultaneously, the extension rod 21 on the rotating component slides in the first support frame 14, carrying the auxiliary wheel 9 along with it. At the same time, the limiting position on the positioning component 10... Block 18 also slides in the limiting groove 20 of the rotating frame 8. When the device is used in different spraying directions, the auxiliary wheel 9 cannot remain unchanged. At this time, the positioning member 10 can be pulled so that the positioning member 10 can slide in the second support frame 16 and squeeze the first spring 11. The positioning block 17 on the positioning member 10 also disengages from the positioning hole 19 in the second support frame 16. At this time, the positioning member 10 is rotated. Under the action of the limiting block 18 and the limiting groove 20, the rotating member starts to rotate, and the friction plate 12 at one end of the first spring 11 slides in the second support frame 16, so that the position of the auxiliary wheel 9 can also change. After the change is completed, the positioning member 10 can be released so that the positioning block 17 is engaged with the positioning hole 19, thereby fixing the lateral position of the rotating frame 8.

[0034] Example 2:

[0035] In summary, during use, different nozzles 2 need to be replaced according to the different spraying tasks. The nozzle 2 can be installed on the external connector 4. The sealing gasket 24 on the nozzle 2 connects with the sealing groove 26 on the external connector 4. After the nozzle 2 enters the cover 5, the cover 5 is rotated so that the first locking block 25 on the nozzle 2 connects with the first locking hole 27 on the cover 5. Simultaneously, the mounting sleeve 3 is rotated so that the internal thread 23 on the mounting sleeve 3 engages with the external thread 22 on the external connector 4, thereby pulling the cover 5 closer to the main body 1. During this process, the first locking hole 27 in the cover 5 directly engages with the first locking block 25 on the nozzle 2, thus fixing the nozzle 2 to the main body 1. Furthermore, the distance between the nozzle 2 and the sofa needs to be controlled. The position of the rotating frame can be adjusted to a suitable position first. Then, the second locking block 29 in the sliding frame 6 can be pulled, causing the second locking block 29 to compress the second spring 30 and disengage from the second locking hole 28 on the main body 1. Then, the cover 5 is pushed... The sliding frame 6, mounted on the main body 1, slides in the sliding groove 15 along with the roller 7. At the same time, the extension rod 21 on the rotating component slides in the first support frame 14 and slides with the auxiliary wheel 9. Simultaneously, the limiting block 18 on the positioning component 10 also slides in the limiting groove 20 of the rotating frame 8. When the device is used in different spraying directions, the auxiliary wheel 9 cannot remain unchanged. At this time, the positioning component 10 can be pulled so that it can slide in the second support frame 16 and squeeze the first spring 11. The positioning block 17 on the positioning component 10 also disengages from the positioning hole 19 in the second support frame 16. When the positioning component 10 is rotated, the rotating component starts to rotate under the action of the limiting block 18 and the limiting groove 20. The friction plate 12 at one end of the first spring 11 slides in the second support frame 16, so that the position of the auxiliary wheel 9 can also change. After the change is completed, the positioning component 10 can be released so that the positioning block 17 engages with the positioning hole 19, thereby fixing the lateral position of the rotating frame 8.

[0036] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
