Description

Technical Field

[0001] This utility model relates to the field of meltblown equipment technology, and in particular to a meltblown equipment for processing automotive sound-absorbing cotton. Background Technology

[0002] Sound-absorbing cotton is a type of man-made inorganic fiber. It uses natural minerals such as quartz sand, limestone, and dolomite as the main raw materials, and combines them with some chemical raw materials such as soda ash and borax to melt them into glass. In the molten state, it is blown into flocculent fine fibers by external force. The fibers are three-dimensionally intertwined and entangled with each other, presenting many tiny gaps.

[0003] Existing meltblown spraying equipment typically has fixed nozzle modules, which makes maintenance of these modules cumbersome. Furthermore, when nozzles need to be replaced according to product requirements, the fixed nozzles require longer replacement times, resulting in low production efficiency. Therefore, this utility model proposes a meltblown spraying equipment for processing automotive sound-absorbing cotton to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the problem that the nozzle module groups of existing meltblown equipment are generally fixedly installed, which makes maintenance of the nozzle module groups cumbersome. Furthermore, when nozzles need to be replaced according to product requirements, the fixed nozzles require longer replacement times, resulting in low production efficiency. Therefore, this invention proposes a meltblown equipment for processing automotive sound-absorbing cotton.

[0013] As a preferred embodiment of this utility model, the positioning mechanism includes: a positioning box, a spring, a moving plate, a transmission plate, a horizontal plate, a pull ring, an insert plate, and a positioning inclined block;

[0014] The front and rear sides of the bottom of the top plate are fixedly connected to the positioning box. There are two springs, both of which are fixedly installed in the inner cavity of the positioning box and located on opposite sides of the two positioning boxes. The opposite sides of the two springs are fixedly connected to the moving plate. The right side of the moving plate is fixedly connected to the transmission plate. There are two transmission plates.

[0019] By pulling the pull ring, the horizontal plate, transmission plate, moving plate, and positioning wedge block are moved. Then, when the positioning wedge block moves, it separates from the insertion hole and contacts the limiting position of the insertion plate. Then, the worker can quickly disassemble the nozzle module assembly. To replace the nozzle module assembly, the insertion plate needs to be inserted into the positioning box. The positioning wedge block will be inserted into the insertion hole by the spring, which can achieve the effect of quickly replacing the nozzle module assembly.

The positioning box 5 has an insertion hole on the front side of the insertion plate 11. The opposite sides of the two moving plates 7 are fixedly connected to the positioning inclined blocks 12. The opposite sides of the two positioning inclined blocks 12 extend into the inner cavity of the insertion hole. By pulling the pull ring 10, the horizontal plate 9, the transmission plate 8, the moving plate 7, and the positioning inclined blocks 12 are moved. Then, when the positioning inclined blocks 12 move, they separate from the insertion hole and limit the insertion plate 11. Then, the worker can quickly disassemble the nozzle module assembly 13.
