Embodiment 1

[0031] as attached figure 1 to attach Image 6 Shown:

[0032] The invention provides a sanitary napkin pulp sheet drying and anti-cracking equipment, the structure of which is provided with a box body 1, a door 2, and a control panel 3, the door 2 is hingedly connected to the front and rear ends of the box body 1, and the control panel The panel 3 is integrated with the box body 1 and is located above the front outer side thereof.

[0033] The box body 1 is provided with an outer frame 11, a drying chamber 12, a carrier frame 13, a heating cover 14, and a heat conduction plate 15. The drying chamber 12 is located inside the outer frame 11, and the heating cover 14 penetrates the outer frame. 11, the heat conducting plate 15 is located at the bottom of the carrier 13, and the carrier 13 is installed in the drying chamber 12.

[0034] Wherein, the carrier frame 13 is provided with a supporting frame 131, a supporting device 132, and an exhaust pipe 133. The exhaust pipe 133 ...

Embodiment 2

[0040] as attached Figure 7 To attach Figure 9 Shown:

[0041] Wherein, the tilting plate a24 is provided with a through plate c1, a petal block c2, and a heat absorbing block c3, the petal block c2 is connected outside the through plate c1, and the heat absorbing block c3 is embedded and movable inside the through plate c1, so There are three petal blocks c2, which are deformable. There are two heat-absorbing blocks c3, which have thermal expansion characteristics. The mouth is deformed in cooperation with the flap c2.

[0042] Wherein, the valve block c2 is provided with an air cushion c21, a spring frame c22, and a side passage block c23. Embedded in the air cushion c21 and movably matched, the air cushion c21 is petal-shaped and has good resilience, the side passage block c23 is provided with an air flow path that gradually expands from the inside to the outside, and the elastic frame c22 is displaced with the pressure of air cushion c21, and the reaction is benefici...

Abstract

The invention discloses papermaking, drying and cracking-preventing equipment for sanitary napkin pulp sheets. The equipment is structurally provided with a box body, a blocking door and a control panel, wherein the blocking door is hinged to the front end and the rear end of the box body, the control panel and the box body are of an integrated structure and are located above the front outer side of the box body, and the box body is provided with an outer frame, a drying chamber, a bearing frame, a heating cover plate and a heat conduction plate. According to the invention, a tilting and swinging plate gradually swings and folds by taking a side end as a fulcrum under the telescopic elasticity of a connecting rod, so the counteraction of a displacement rod is facilitated to serve as the lower end supporting force of the tilting and swinging plate, and the tilting and swinging plate is allowed to have larger angle change; gas is driven by the displacement of clamping blocks and an actuating plate to generate gas flow force for discharging towards two sides, so the tilting and swinging plate generates inward adsorption force from inside to outside; and the upper end of a relatively dried pulp sheet has adsorption force which plays a role in stabilizing the position of the pulp sheet, and a relatively dried position is far away from a ceramic plate, so the phenomenon that partial area of the pulp sheet is excessively dried to cause wrinkling and cracking is prevented.

Description

technical field [0001] The invention belongs to the field of equipment for making pulp sheets for sanitary napkins, and more specifically relates to a drying and cracking prevention equipment for pulp sheets for sanitary napkins. Background technique [0002] Sanitary napkins are mainly products made of cotton, fiber, non-woven fabrics and other materials. In order to enhance absorbency, fluff pulp is also used in sanitary napkins. In the production process of sanitary napkins, it is necessary to make sanitary napkin pulp sheets. Drying, so that the sanitary napkin pulp can better absorb water. [0003] Based on the inventor's discovery above, there are following deficiencies in the existing sanitary napkin pulp making, drying and anti-cracking equipment: [0004] Because the paddles cannot be pressed tightly, it is necessary to ensure that there is a gap in the internal materials. During the drying operation, the paddles will be distorted and deformed due to heat and dryin...
