Description

Technical Field

[0001] The utility model belongs to the field of pearl cotton production, in particular to a pearl cotton shaping bracket. Background Art

[0002] During the production and processing of pearl cotton, there is a certain distance between the extruder head and the blower head. The pearl cotton located between the two will sag due to its own weight. After sagging, the thickness of the formed pearl cotton will be uneven, affecting the quality of the product. For this reason, operators usually place a bracket in this distance to support the pearl cotton.

[0003] However, the traditional bracket structure is simple and can only support the bottom of the EPE foam, but cannot limit the sides of EPE foam with different diameters. This makes the EPE foam easy to swing left and right when passing through the bracket, resulting in uneven thickness of the formed EPE foam. Since there is no limit on the sides of the EPE foam, the swing of the EPE foam may affect the molding quality of the EPE foam and increase the scrap rate.

[0004] In view of this, we proposed the pearl cotton shaping bracket to solve this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an EPE shaping bracket to solve the problems raised in the above background technology.

[0006] The utility model is realized by the following technical solutions: the pearl cotton shaping bracket comprises: a supporting roller frame and an idler, wherein an idler is installed above the supporting roller frame, and a side roller frame is respectively provided on the left and right sides above the idler, and a side limiting roller is respectively installed in the two side roller frames;

[0007] A special-shaped adjustment rod is installed on the back of each of the two side roller frames, and a hollow support rod is provided under the support roller frame, and a movable groove is provided in the hollow support rod;

[0008] A driving slider is installed at the lower end of each of the two special-shaped adjusting rods. A threaded hole is opened in the middle of the driving slider. A bidirectional threaded rod is installed in the threaded hole. The thread directions on both sides of the bidirectional threaded rod are opposite. A servo motor is installed on the right side of the hollow support rod.

[0009] As a preferred embodiment, the output shaft of the servo motor is connected to the right end of the bidirectional threaded rod, a bearing is installed on the left side inside the movable groove, and the left end of the bidirectional threaded rod is connected to the inner side of the bearing.

[0010] As a preferred embodiment, the left side of the bidirectional threaded rod is a left-handed thread, and the right side is a right-handed thread.

[0011] As a preferred embodiment, the support roller frame is connected to the hollow support rod through an intermediate support block at the bottom.

[0012] As a preferred embodiment, a clearance groove is provided under each of the special-shaped adjustment rods.

[0013] As a preferred embodiment, an electric push rod is installed below the hollow support rod, and a base is installed below the electric push rod.

[0014] As a preferred embodiment, a hollow guide rod is installed on the left and right sides above the base respectively, and a guide rod is provided above the two hollow guide rods respectively, and the upper ends of the guide rods are connected to the hollow support rods.

[0015] After adopting the above technical solution, the beneficial effects of the utility model are:

[0016] 1. By setting the side limit roller, driving slider, special-shaped adjustment rod, bidirectional threaded rod, threaded hole and servo motor, it is possible to adjust the distance between the two side limit rollers according to the diameter of the pearl cotton of different diameters, thereby limiting the left and right sides of the pearl cotton, which can effectively prevent the pearl cotton from swinging left and right during the extrusion process, thereby ensuring that the thickness of the formed pearl cotton is uniform.

[0017] 2. By setting up an electric push rod, a hollow guide rod and a guide rod, it is easy to drive the support roller frame to stably rise and fall, thereby facilitating the adjustment of the support height of the roller. This adjustable design can easily adapt to various situations. Whether it is to cooperate with different models of extruders or to meet special production process requirements, the best support effect can be achieved by adjusting the roller height.

[0033] See also Figures 1 to 3 As the first embodiment of the present utility model: in actual use, the bracket is placed between the extruder head and the blower head, and then the hollow support rod 7 is driven up and down by the electric push rod 11, so as to facilitate the adjustment of the support height of the roller 2 according to the actual use situation. When the hollow support rod 7 is raised or lowered, the guide rod 13 can be driven to rise and fall in a straight line along the internal path of the hollow guide rod 14, thereby improving the stability of the lifting and lowering adjustment of the hollow support rod 7.

[0034] See also Figures 1 to 3 , as a second embodiment of the present invention: according to the further elaboration of the first embodiment, after the height adjustment is completed, the distance between the two side limit rollers 4 can be adjusted according to the diameter length of the extruded pearl cotton.
