Description

A positioning mechanism for interior ceiling surface fabric

The technical field is as follows:

the utility model relates to the technical field of automobile ceilings, in particular to a limit pin nail for positioning interior ceiling fabrics; the method is mainly used for positioning the fabric during ceiling forming and compounding and preventing the fabric from wrinkling.

Background art:

the two production processes are mainly characterized in that a PU plate roller is glued and sprinkled with water, non-woven fabric and glass fiber are paved and then molded in a compression mode, and then in the process of compounding the fabric, the mold is too much in shape, the fabric is stressed unevenly, the edge is not pulled and pulled flat, the phenomenon that the finished fabric is wrinkled is caused, the appearance of the product is greatly influenced, and the quality of the product is greatly influenced.

The mode of solving this fold at present is mostly the ordinary needle nail of four corners direct weld perpendicular and mould, and the operator is to hanging the position of surface fabric in the production process, highly hardly holds, requires highly to the operator, and the experience is not enough to cause the surface fabric fold very easily, causes the product to scrap.

The utility model has the following contents:

the utility model aims at overcoming the defects of the prior art and providing a limit pin nail for positioning interior ceiling fabrics.

The utility model provides a technical scheme is: a positioning mechanism for interior ceiling fabric comprises a lower die and needle nails, and is characterized in that the needle nails are respectively connected with four corners of the lower die; the needle nail is formed by fixing a needle nail limiting head at the front end and a needle nail rod at the rear end, the front end of the needle nail limiting head is in a conical shape, and the needle nail rod is in a cylindrical shape; the needle nail and the lower die form an angle of 30-45 degrees, and the length of the needle nail extending out of the die is 5-10 cm.

Furthermore, the pin nail limiting head of the pin nail consists of a cone and a cylinder at the front end, and a limiting boss is arranged at the joint of the pin nail limiting head and the pin nail rod at the rear end and is in a step connection mode; the boss plays limiting role in the upper position and the lower position of the fabric, and the fabric is prevented from being inconsistent in height.

Furthermore, two limiting pieces are arranged at the joint of the needle nail limiting head at the front end of the needle nail and the needle nail rod at the rear end of the needle nail, and the included angle between the two limiting pieces is 90 degrees; the pin plays the limiting role in the front, back, left and right positions of the fabric, and prevents the fabric from being hung partially.

The utility model has the advantages that: 1. the limiting pins are fixed at the four corners of the lower die, so that the limiting pins have a limiting effect on the upper position, the lower position, the front position, the rear position, the left position and the right position of the fabric, the height of the fabric is prevented from being inconsistent, the fabric is prevented from being hung and deflected, the fabric is positioned on the die, meanwhile, the fabric is uniformly stressed in the ceiling forming process, and the problem of wrinkling caused by the fact that the fabric is not stretched and the fabric is hung and deflected when the ceiling is compounded; 2. the requirement on the skill of people is reduced, and the production efficiency is improved.

Description of the drawings:

fig. 1 is a schematic structural view of the present invention;

FIG. 2 is a schematic view of a structure of the nail according to the present invention;

fig. 3 is another schematic structural diagram of the nail of the present invention.

The specific implementation mode is as follows:

for a further understanding of the present invention, reference will now be made in detail to the present invention, examples of which are illustrated in the accompanying drawings.

Embodiment 1, as shown in fig. 1 and 2, a positioning mechanism for an interior ceiling fabric includes a lower mold 1 and a pin 2, the pin 2 is formed by fixing a pin limiting head 3 at a front end and a pin rod 4 at a rear end, the pin limiting head 3 of the pin 2 is formed by a cone and a cylinder at the front end, and the pin rod 4 is cylindrical; the joint of the pin limiting head 3 and the pin rod 4 at the rear end is provided with a limiting boss 5, the pin limiting head and the pin rod are fixedly connected into a whole in a stepped manner, and the boss 5 plays a role in limiting the upper position and the lower position of the fabric to prevent the fabric from being inconsistent in height; the total length of the pin 2 is 15-25cm, the diameter is 3-10cm, and the length of the pin limiting head 3 is 2-6 mm; the needle nails 2 are fixedly arranged at four corners of the lower die 1 by screws respectively, an angle of 30-45 degrees is formed between the needle nail 2 and the lower die 1, and the length of the needle nail 2 extending out of the die is 5-10 cm.
