Description

Technical Field

[0001] This utility model relates to the field of spring flocking technology, and in particular to a spring flocking production line equipment. Background Technology

[0002] With the core characteristics of shock absorption, noise reduction, anti-slip and wear resistance, and soft touch brought by the flock layer, spring flocking products have become key components in high-end fields such as car seat shock absorption springs, home sofa seat springs, and precision instrument shock absorption springs. The flocking process of spring flocking thread is a core link that uses specific processes to orient and firmly attach the flock (such as nylon, polyester, viscose and other materials) to the surface of the spring thread, giving it functions such as soft touch, anti-slip and wear resistance, and decorative appearance.

[0003] Patent CN207899626U discloses a flocking spring production line equipment. The flocking section consists of an electric field and a flocking device. The flocking device feeds the flock into the electric field via guide rails and conveying pipes to complete the flocking process. A flock recovery device is located at the bottom of the electric field. The equipment inside the drying oven is electrically heated, and the flocked springs are heated and the adhesive is cured as they pass through the oven, achieving a stable flocking effect. This utility model is a fully automatic flocking production line. Except for loading and unloading, there is no manual intervention throughout the process, ensuring maximum consistency and stability of operations, enabling large-scale industrial production of flocked electric tailgate springs.

[0004] While the aforementioned technology can deliver the flock into the electric field via guide rails and conveying pipes to complete the flock implantation, the flock tends to clump together during storage. This clumping of the flock leads to uneven flocking during transport and implantation, affecting the flocking effect. Therefore, the above problems need to be solved. Utility Model Content

[0020] 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.

[0021] Example

[0022] Please see Figures 1-4 This utility model provides a technical solution:

[0023] A spring flocking production line includes a loading area 2, a glue spraying area 3, a flocking area, a drying chamber 6, and an unloading area 8 arranged sequentially. It also includes a conveyor line 1 that runs through the loading area 2, glue spraying area 3, flocking area, drying chamber 6, and unloading area 8 to transport springs to be flocked. The glue spraying area 3 is equipped with an electrostatic automatic glue spray gun 31 for spraying glue onto the surface of the springs to be flocked. The flocking area is equipped with an automatic flocking system for flocking the glue-coated spring surfaces. The drying chamber 6 is used to dry and cure the flocked springs. A waste exhaust system 9 is connected above the drying chamber 6. The waste exhaust system 9 includes a waste exhaust outlet 91, a connecting pipe 92, and an exhaust pipe 93. The waste exhaust outlet 91 is connected to the exhaust pipe 93 via the connecting pipe 92. The production line is constructed by sequentially connecting the loading area 2, glue spraying area 3, flocking area, drying chamber 6, and unloading area 8. 2. The assembly includes a glue spraying area 3, a flocking area, a drying chamber 6, and an unloading area 8, along with a continuous conveyor line 1, enabling continuous operation of spring flocking from loading and unloading, glue spraying, flocking to drying, significantly improving production continuity and efficiency. The electrostatic automatic glue spraying gun 31 in the glue spraying area 3 can automatically spray glue, ensuring the uniformity and accuracy of the glue layer coating, providing a stable foundation for subsequent flocking. The automatic flocking system in the flocking area automates the flocking process, reducing manual intervention to improve flocking consistency. The drying chamber 6 can effectively dry and cure the flocked springs, ensuring that the flocking is firmly attached. The waste exhaust system 9, consisting of a waste exhaust port 91, a connecting pipe 92, and an exhaust pipe 93 connected above the drying chamber 6, can promptly discharge the waste gas generated during drying, improving the production environment, and comprehensively considering production efficiency, product quality, and environmental protection requirements.

[0024] Please see Figure 2 and 3 The conveyor line 1 includes a sprocket 11, a chain 12, and multiple shafts 13. The chain 12 is sleeved on the sprocket 11, and the multiple shafts 13 are spaced apart on the chain 12. The shafts 13 are used to install the springs to be flocked. The cooperation between the sprocket 11 and the chain 12 achieves stable and continuous transmission, ensuring a smooth and orderly conveying process and providing a foundation for the precise operation of subsequent processes. The multiple shafts 13 spaced apart on the chain 12 can independently install the springs to be flocked, avoiding mutual interference between the springs, and can also realize the synchronous conveying of multiple springs, greatly improving the conveying efficiency. The shafts 13 are directly used to install the springs, with clear positioning, which can ensure the stability of the springs during the conveying process and prevent deviation from affecting the accuracy of subsequent processes such as spraying glue and flocking. The overall structure is simple and reliable, and is suitable for continuous and batch production needs.

[0025] Please see Figure 4The flocking area includes a first flocking area 4 and a second flocking area 5. The first flocking area 4 is equipped with a first automatic flocking system 41, and the second flocking area 5 is equipped with a second automatic flocking system 51. Both the first automatic flocking system 41 and the second automatic flocking system 51 include a flocking trough for storing and dispersing the flock fibers and an electrode plate for controlling the spraying of the flock fibers from the negative electrode direction. The arrangement of the first flocking area 4 and the second flocking area 5 forms a multi-stage flocking process, which can perform multiple flocking treatments on the spring, significantly improving the uniformity and density of the flock coverage. The flocking trough can fully disperse the flock fibers, effectively solving the problem of flock fiber clumping and ensuring that the flock fibers participating in the flocking are evenly dispersed. The electrode plate can accurately guide the flock fibers to attach to the spring surface, ensuring the orientation and firmness of the flocking. Through multi-zone collaboration and structural optimization, the stability and consistency of the flocking quality are greatly improved.

[0026] Please see Figure 4 The electrostatic automatic glue spray gun 31 is installed in the glue spraying area 3 via an adjustable bracket. The adjustable bracket can adjust the spraying angle and height of the electrostatic automatic glue spray gun 31. The adjustable bracket can flexibly adjust the spraying angle and height of the electrostatic automatic glue spray gun 31 to ensure that the glue evenly covers the spring surface and the spiral gap, avoid local missed coating or excessive glue layer, and lay a uniform glue layer foundation for the firm adhesion of the flock in the subsequent flocking process.

[0027] Please see Figure 1 The drying chamber 6 is equipped with multiple heating tubes, which are evenly distributed along the conveying direction of the conveyor line 1. The drying chamber 6 is also equipped with a temperature control system, which is used to control the temperature inside the drying chamber 6. The heating tubes can create a uniform temperature field inside the drying chamber 6, avoiding the problem of insufficient curing or excessive charring of the adhesive layer due to uneven local heating during the conveying and drying process of the springs, and ensuring that each flocked spring is in a stable drying environment.

[0028] Please see Figure 1 An automatic reciprocating air chamber 7 is provided on one side of the unloading area 8. The automatic reciprocating air chamber 7 is used to remove the dried springs from the shaft 13 of the conveyor line 1 and transport them to the unloading area 8. It can automatically complete the removal of the dried springs from the shaft 13 of the conveyor line 1 and the transport to the unloading area 8 without manual intervention.

[0029] Please see Figure 2 The shaft 13 is a detachable structure, and the outer surface of the shaft 13 is provided with a positioning structure. The positioning structure is used to stably fix the spring to be flocked. The detachable structure can flexibly adapt to springs of different diameters and pitches. When the production specifications are changed, there is no need to replace the transmission components of the entire conveyor line 1. Only the shaft 13 of the corresponding specification needs to be quickly replaced, which greatly shortens the changeover time, improves the adaptability of the equipment to the production of multiple types of springs, and reduces the production line transformation cost.

[0030] Working principle: First, in the loading area 2, the spring to be flocked is installed on the shaft 13 of the conveyor line 1. The positioning structure on the outer surface of the shaft 13 is used to achieve stable fixation. If the spring specifications are different, a suitable detachable shaft 13 can be replaced. Then, the sprocket 11 of the conveyor line 1 drives the chain 12 to rotate, and the spring is conveyed to each process in sequence. After the spring enters the glue spraying area 3, the spraying angle and height of the electrostatic automatic glue spraying gun 31 are adjusted by the adjustable bracket to evenly spray glue onto the surface of the spring. Then the spring is conveyed to the first flocking area 4 and the second flocking area 5. The flocking troughs in the first automatic flocking system 41 and the second automatic flocking system 51 first fully disperse the flock, and then pass through the electrode plate. The constructed electrostatic field causes the flocking fibers to be sprayed directionally from the negative electrode direction and evenly adhered to the adhesive layer on the surface of the spring. The flocked springs are then conveyed to the drying chamber 6. Heating tubes evenly distributed along the conveying direction inside the chamber are precisely temperature-controlled and dried under the regulation of the temperature control system to solidify the adhesive layer and ensure that the flocking fibers are firmly attached. The dried springs are then conveyed to the unloading area 8. The automatic reciprocating air chamber 7 removes the springs from the shaft 13 and conveys them to the unloading area 8 to complete the material collection. At the same time, the waste gas generated during the drying process is discharged through the waste exhaust system 9, which consists of the waste exhaust port 91, connecting pipe 92, and exhaust pipe 93 above the drying chamber 6, realizing the fully automated spring flocking operation.
