The molding apparatus and the molding system of the present application will be described below with reference to the drawings.

FIG. 1 is a schematic structural diagram of a molding apparatus according to an embodiment of the present disclosure; fig. 2 is a schematic structural view of the molding apparatus shown in fig. 1 from another perspective. For the purpose of illustration, only the structures described in connection with the present application are illustrated in the drawings.

The forming apparatus 10 disclosed in at least one embodiment of the present application includes a forming wire 110, a forming head 120, and a forming vacuum 130. The forming wire 110 has a first side 111 and a second side 112 opposite to the first side 111, the forming head 120 is arranged at the first side 111 of the forming wire 110, and the forming vacuum 130 is arranged at the second side 112 of the forming wire 110 for creating an air flow directed from the first side to the second side.

In some embodiments, the forming head 120 includes a forming frame 121, a circular screen 122, a drive roller 123, and an agitator roller 124. In some embodiments, the forming frame 121 is a metal frame formed by splicing a plurality of metal frames and adapted to mount the fiber material processing components such as the circular screen 122, the driving roller 123 and the stirring roller 124. The circular screen 122 is arranged in the forming frame 121 in a penetrating manner and is provided with a material conveying opening, the material conveying opening is used for conveying fiber materials into the circular screen 122, and the circular screen 122 is also provided with screen holes. The driving roller 123 is rotatably connected to the forming frame 121, and is configured to hold the circular screen 122 in the forming frame 121 and drive the circular screen 122 to rotate around its central axis. The circular screen 122 is further provided with a stirring roller 124, and the stirring roller 124 is rotatably connected to the forming frame 121, and is opposite to the rotation direction of the circular screen 122, and is used for opening and stirring the fiber material input into the circular screen 122 from the feeding port in cooperation with the circular screen 122.

In practical application, after the fiber material enters the rotating circular screen 122, the rotating direction of the stirring roller 124 is opposite to the rotating direction of the circular screen 122, and the circular screen 122 can be matched with the stirring roller 124 to stir and loosen the fiber material, so that the fiber material is fully fluffy. The holes in the circular screen 122 have a screening effect, and only the fibrous material which is fully fluffed can pass through the holes. Since the forming vacuum 130 creates an air flow directed from the first side to the second side, the fluffed fibrous material can fall through the openings in the circular screen 122 and onto the forming wire 110, thereby forming a fluffy, continuous, non-lumpy fibrous material layer.

In some embodiments, the shape of the holes on the circular screen 122 may be triangular, rectangular, or oval. As a preferred embodiment, the shape of the sieve openings is chosen to be oval. Therefore, the forming machine is beneficial to the processing and forming of the sieve pores, and is also beneficial to improving the screening effect of the sieve pores, so that the fiber material layer paved on the forming net 110 is more uniform. It is to be understood that the above examples are for illustrative purposes only and are not to be construed as limiting the present application. For example, the shape of the sieve holes can be round, and the screening effect of the sieve holes is not affected.

In some embodiments, the mesh is oval in shape, with the major axis of the mesh being 6mm to 100mm and the minor axis of the mesh being 2.5mm to 10 mm. Thus, the screening function of the sieve pores can be ensured. It will be appreciated that the size of the mesh should be adapted to ensure that a uniform, continuous layer of fibrous material is formed, depending on the length of the fibrous material.

In some embodiments, the stirring roller 124 is provided with a stirring member for opening and stirring the fiber material entering the circular screen 122. The stirring member includes a projection member and a mounting member, and the projection member is fastened to the stirring roller 124 by the mounting member. In particular to some embodiments, the projections are spikes and the mounting members are nailing strips. In practical application, the circular screen 122 and the stirring roller 124 rotate in opposite directions, and the protruding parts rotate together with the stirring roller 124, and simultaneously, the fiber materials in the circular screen 122 are subjected to opening and carding. In this manner, the fiber material can be sufficiently opened to improve the uniformity and continuity of the layer of fiber material laid on the forming wire 110.

In some embodiments, the forming apparatus 10 further comprises a feed roll drivingly connected to the second side 112 of the forming wire 110 to enable the forming wire 110 to reciprocate in one direction between the forming head 120 and the forming vacuum 130. Specifically, in practical use, the fluffed fiber material falls onto the forming screen 110 through the screen holes of the circular screen 122, and the feeding roller drives the forming screen 110 to move along one direction. In this way, it is possible to ensure that the layer of fibrous material laid onto the forming wire 110 is continuous and uniform.

In some embodiments, the forming vacuum 130 includes a vacuum housing 131, a pumping port 132, a suction port 133, and a pumping unit. The suction opening 132 and the suction opening 133 are disposed on the surface of the vacuum housing 131, wherein the suction opening 133 is disposed toward the second side 112 of the forming net 110, and the suction opening 132 is communicated with the suction unit. In particular to some embodiments, the air extraction unit is an air extraction fan. In practice, when the air-extracting unit is in operation, air enters from the air inlet 133 and then enters the air-extracting unit from the air outlet 132 and is exhausted, thus forming an air flow directed from the forming head 120 to the forming vacuum 130. After the fibrous material has been sufficiently opened and agitated in the circular screen 122, the opened and agitated fibrous material is subjected to the air flow so that it passes through the openings and falls down onto the forming wire 110 to form a fluffy fibrous material layer.

In some embodiments, the forming vacuum 130 further comprises air-evening pieces spaced apart in the vacuum housing 131. In some embodiments, the air-uniforming member is a plate-shaped member, and is spaced apart from the vacuum housing 131 along the length of the vacuum housing 131. In this way, the consistency of the air flow through the forming wire 110 is improved, thereby improving the continuity and uniformity of the layer of fibrous material laid onto the forming wire 110.

In some embodiments, the molding device 10 further includes a first driving member, a second driving member, and a third driving member. The first driving member, the second driving member and the third driving member are respectively connected to the driving roller 123, the stirring roller 124 and the feeding roller in a transmission manner. In some embodiments, the first driving member, the second driving member and the third driving member are motors, and the motors have output ends connected to the driving roller 123, the stirring roller 124 and the feeding roller.

In some embodiments, the molding apparatus 10 further includes a controller in signal communication with the first, second, and third driving members. Particularly, in practical application, the controller is connected to the first driving member and the second driving member through signals, and the rotating speeds of the driving roller 123 and the stirring roller 124 are adjusted according to the filling power of the fiber materials entering the circular screen 122, so that the opening and stirring effects of the fiber materials can be ensured on the basis of reducing energy consumption, and fluffy fiber materials are formed. The controller is connected with the third driving member through signals, and the rotating speed of the feeding roller is adjusted, so that the fiber material layers with different thicknesses can be formed on the forming net 110.

The forming system comprises a supply device and the forming device 10 for forming a fluffy fibrous material layer. The feeding device comprises a feeding pipe and a feeding fan, the feeding pipe is communicated with a material conveying port of the circular screen 122, and the fiber materials can enter the circular screen 122 from the feeding pipe through the wind power of the feeding fan. Thus, automatic feeding of the molding apparatus 10 can be realized.

In the molding apparatus 10 and the molding system, the circular screen 122 is driven by the driving roller 123 and rotates around an axis, the stirring roller 124 is disposed in the circular screen 122, and the rotation direction of the stirring roller 124 is opposite to the rotation direction of the circular screen 122. After the fiber material enters the rotating circular screen 122, the circular screen 122 cooperates with the stirring roller 124 to loosen and stir the fiber material, so that the fiber material is fully fluffy. Because the forming vacuum member 130 is provided with the air-homogenizing member therein, a uniform air flow directed from the first side to the second side can be formed, and the fluffy fiber material can fall down from the screen holes of the circular screen 122 along with the air flow and is laid on the forming screen 110, thereby forming a fluffy, continuous and non-caking fiber material layer.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
