Description

Technical Field

[0001] The utility model relates to a SAP quantitative spreading device. Background Art

[0002] In disposable absorbent products such as diapers, sanitary napkins, breast pads and other products, SAP is usually added to improve the liquid absorption performance. For this purpose, a SAP quantitative addition device is used in the production equipment to add SAP to the core.

[0003] Existing SAP quantitative addition devices usually adopt the method of knurling or grooving on the roller. When the roller rotates, the SAP particles filled in the grooves on its surface are taken out from the silo and released. Regardless of knurling or grooving, the SAP particles cannot completely fill the grooves, and the filling amount changes nonlinearly with the change of roller speed. Therefore, during high-speed operation, the accurate quantitative addition of SAP particles cannot be guaranteed, thereby affecting product quality.

[0004] In further improvements, CN207580928U shows a quantitative adding device, in which the lower opening of the silo is arranged near the belt, and the SAP discharged from the silo is supported and spread when the belt rotates. However, it is found in practice that this method still fails to completely solve the problem of SAP absorbing moisture. More specifically, the SAP still becomes compacted or adheres to the belt after absorbing moisture.

[0025] At the same time, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0026] Please refer to the attached Figure 1-Figure 4 The SAP quantitative spreading device includes a feeding component and a spreading component.

[0027] The feeding assembly includes a hopper 11 and a feeding pipe 12 arranged below the hopper 11. The hopper 11 is used to hold SAP, which is also called a polymer absorbent resin. Usually, SAP is granular and has a particle size of 20 to 500 μm. Of course, in this embodiment, the SAP can have a larger or smaller particle size. In addition, the SAP is usually sodium polyacrylate particles, and can also be other suitable granular materials, which are not limited here.

[0028] The hopper 11 generally comprises a tubular body with a circular cross section and a conical tube body located below the tubular body. The SAP contained in the tubular body can easily flow into the feeding pipe 12 along the conical tube body under the action of gravity.

[0029] The feed pipe 12 includes a feed channel 120 surrounded by a side wall 121. In the present embodiment, the feed channel 120 is vertically oriented, and the end of the feed channel 120 includes a channel outlet 1200. SAP falls from the channel outlet 1200 onto the spreading assembly and is spread downstream by the spreading assembly.

[0030] A heating device is also provided on the outside of the side wall 121, and the heating device includes a heat spreader 122 and a heating tube 123 arranged on the heat spreader 122. The heat spreader 122 is heated by the heating tube 123, and the corresponding feeding channel 120 is heated by the heat spreader 122. In this way, on the one hand, it is avoided that the heating device directly heats the feeding channel 120 and causes uneven temperature. On the other hand, the heating device is arranged on the outside of the side wall 121, which will not hinder the movement of SAP in the feeding channel 120, so that SAP can pass through the feeding channel 120 smoothly.

[0031] In this embodiment, the feeding tube 12 is in the shape of a rectangular tube, and the side wall 121 includes a first side wall 121 and a second side wall 121 that are opposite to each other, and a third side wall 121 and a fourth side wall 121 that are opposite to each other and connect the first side wall 121 and the second side wall 121. There is a pair of heating devices, and the pair of heating devices are respectively arranged on the first side wall 121 and the second side wall 121. The heat spreaders 122 are in the shape of rectangular flat plates and are respectively attached to the outer sides of the first side wall 121 and the second side wall 121.

[0032] The heat spreader 122 includes a length direction, a width direction and a thickness direction, wherein the length direction of the heat spreader 122 is a vertical direction, the width direction is a horizontal direction, and the thickness direction is a direction perpendicular to the length direction and the width direction. Figure 1 In the middle, it is perpendicular to the paper surface. The heat spreader 122 also includes a through hole that runs through the heat spreader 122 in the width direction. The heating tube 123 is arranged in the through hole. It can be understood that the heating tube 123 is in a horizontal direction.

[0033] Furthermore, at least two heating tubes 123 are disposed on each heat spreader 122. Preferably, there is a pair of heating tubes 123, which are spaced apart in the vertical direction.

[0034] Furthermore, a holding piece 1231 is provided on the heat spreader 122 for fixing the heating tube 123 inserted in the through hole. In the present embodiment, the holding piece 1231 is a holding screw. A screw hole connected to the through hole is provided on the heat spreader 122. The holding screw is threadedly connected in the screw hole, and one end thereof facing the through hole abuts against the heating tube 123 in the through hole, thereby limiting the position of the heating tube 123.

[0035] It can be understood that there is at least one pair of the pressing members 1231 so as to better define the position of the heating tube 123 .

[0036] Furthermore, a temperature sensor 124 is also provided on the heat spreader 122 for monitoring the temperature of the heat spreader 122. When there is a pair of heating tubes 123, the temperature sensor 124 is arranged between the pair of heating tubes 123. More preferably, the temperature sensor 124 is arranged equidistantly from the pair of heating tubes 123.

[0037] Furthermore, the heating tube 123 is an electric heating tube 123, and the temperature sensor 124 is a thermocouple.

[0038] Furthermore, a heat insulating plate is provided on the outer side of the heat spreader 122 to prevent burns.

[0039] The heat spreader 122 includes a lower edge, and the lower edge is spaced apart from the channel outlet 1200 and has a distance of at least 10 mm. More preferably, the distance between the lower edge and the channel outlet 1200 is 12-45 mm.

[0040] An opening adjustment device is also provided on the outer side of the side wall 121 for adjusting the amount of SAP delivered to the spreading assembly. The opening adjustment device includes a first adjustment plate 131 and a second adjustment plate 132 respectively provided on the third side wall 121 and the fourth side wall 121, wherein the structure of the first adjustment plate 131 and the second adjustment plate 132 are basically the same. Only the first adjustment plate 131 is described in detail below, and the second adjustment plate 132 is not described in detail.

[0041] An adjustment support 133 is also provided on the third side wall 121. The adjustment support 133 includes a socket and a protrusion arranged on the upper side of the socket. The first adjustment plate 131 is inserted in the socket and can move movably in the vertical direction. The protrusion is provided with a first adjustment bolt 134. One end of the first adjustment bolt 134 abuts against the first adjustment plate 131 to limit the position of the first adjustment plate 131 in the vertical direction, thereby adjusting the gap between the first adjustment plate 131 and the conveyor belt 23.
