Description

Technical Field

[0001] The utility model relates to the technical field of hot pressing devices, in particular to a hot pressing device. Background Art

[0002] Absorbent paper is one of the main materials for manufacturing sanitary products such as sanitary napkins, diapers, and panty liners. The absorbent core of the prior art often adopts a three-layer structure, with dust-free paper on the upper and lower layers, and one or more layers of non-woven fabric in the middle. The non-woven fabric is a carrier of absorbent particles, and polymer absorbent resin particles are evenly sprayed on the absorbent particle carrier. As the main absorbent material in the absorbent carrier, the polymer absorbent resin has good water absorption and water locking properties. During the production process of absorbent paper, it needs to go through a hot pressing step, so a hot pressing device is required;

[0003] However, during the operation of the existing hot pressing device, the guide rollers arranged on both sides of the hot pressing device can play a good guiding role for the absorbent paper during the hot pressing process. However, when people adjust the height of the guide rollers in the current hot pressing device, they can only adjust the height of the two ends of the guide rollers separately to achieve the height adjustment of the guide rollers. This makes it difficult for people to keep the guide rollers in a horizontal state when adjusting them. If the guide rollers are in a tilted state, the quality of the absorbent paper may be affected.

[0004] In order to solve the above problems, a hot pressing device is proposed in the present application. Utility Model Content

[0005] The utility model is intended to provide a hot pressing device, which is mainly used to solve the problem that it is difficult to keep the guide roller in a horizontal state when adjusting its height on the existing hot pressing device, and if the guide roller is in an inclined state, the quality of absorbent paper may be affected.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A hot pressing device comprises a hot pressing device body and two hot pressing rollers installed on the hot pressing device body, both sides of the hot pressing device body are fixedly connected with a fixed shell, a cavity is opened inside the fixed shell, one side of the inner wall of the cavity is rotatably connected with a worm, the other end of the worm extends out of the fixed shell and is rotatably connected to the fixed shell, and one end of the worm extending out of the fixed shell is fixedly connected with a knob, both ends of the bottom of the inner wall of the cavity are rotatably connected with a worm wheel, the worm wheel is meshed with the worm, a threaded rod is fixedly connected at the axis center of the top of the worm wheel, the threaded rod penetrates the fixed shell and is rotatably connected to the fixed shell, the outer wall of the threaded rod is threadedly connected with a threaded sleeve, the outer wall of the threaded rod is located above the threaded sleeve and is movably connected with a sliding sleeve, the threaded sleeve is rotatably connected to the sliding sleeve, the bottom of the sliding sleeve is fixedly connected with a limiting component, and a guide roller is rotatably connected between the two sliding sleeves located on one side of the hot pressing device body.

[0008] The working principle and beneficial effects of the utility model:

[0009] 1. Working principle: When using the device, connect the device to the power supply, and the controller on the hot pressing device body sends an electrical signal to control the device to start so that the two hot pressing rollers on the hot pressing device body rotate synchronously in opposite directions. The guide rollers arranged on both sides of the hot pressing device body can play a good guiding role for the absorbent paper. When it is necessary to adjust the height of the guide roller, the threaded sleeve and the sliding sleeve are fixed by the limit assembly, and the worm inside the fixed shell can be rotated by turning the knob. When the worm rotates, the two worm wheels inside the fixed shell can rotate synchronously, so that the threaded rod on the top of the worm wheel rotates. When the threaded rod rotates, the threaded sleeve threadedly connected to it can move up and down. The up and down movement of the threaded sleeve can drive the guide roller to move up and down through the sliding sleeve, thereby realizing the adjustment of the height of the guide roller.

[0010] 2. Beneficial effect: A worm and a symmetrical worm wheel are arranged inside the fixed shell. By turning the knob, the two worm wheels can be driven to rotate synchronously through the worm. When the two worm wheels rotate synchronously, the guide rollers can be rotated synchronously through the cooperation of the threaded rod, the threaded sleeve and the sliding sleeve. This not only makes it more convenient for people to adjust the height of the guide rollers, but also makes the guide rollers more horizontal.

[0011] Preferably, the limiting assembly includes a fixed block fixedly connected to the bottom of the sliding sleeve, a plug rod passing through the fixed block, a slot matching the plug rod is opened on the outer wall of the threaded sleeve, and a pull ring is fixedly connected to the end of the plug rod away from the threaded sleeve. When adjusting the height of the guide roller, the plug rod is passed through the fixed block and inserted into the slot on the threaded sleeve, so that the threaded sleeve and the sliding sleeve can be fixed. At this time, the height of the guide roller can be adjusted by turning the knob. After the height of the guide roller is adjusted to an appropriate level, the pull ring is pulled out to pull out the plug rod, and the height of the guide roller can be fine-tuned by rotating the threaded sleeve, thereby further improving the horizontality of the guide roller and thereby improving the production quality of the absorbent paper.

[0012] Preferably, the upper ends of the threaded rods are rotatably connected to connecting blocks, and one side of the connecting blocks is fixedly connected to the hot pressing device body. The connecting blocks set at the upper ends of the threaded rods can not only effectively improve the stability of the threaded rods, but also effectively prevent the sliding sleeve from detaching from the threaded rods, thereby effectively ensuring the normal operation of the device.

[0013] Preferably, one end of the insertion rod close to the threaded sleeve is fixedly connected to a magnet block, and the inner wall of the slot is fixedly connected to an iron sheet attracted to the magnet block. After one end of the insertion rod is inserted into the slot on the threaded sleeve, the magnet block at one end of the insertion rod will be attracted to the iron sheet inside the slot, which can fix the insertion rod to a certain extent, thereby effectively preventing the insertion rod from escaping from the slot when the device is operating.

[0014] Preferably, a level is fixedly connected to one side of the sliding sleeve. By observing the level provided on the sliding sleeve, the staff can more intuitively understand the horizontality of the guide roller by observing the level, thereby facilitating people to adjust the height of the guide roller.

[0015] Preferably, there are multiple slots on the outer wall of the threaded sleeve, and the slots are evenly distributed in a circular array on the outer wall of the threaded sleeve. By setting the number of slots on the outer wall of the threaded sleeve to multiple, the insertion rod can be inserted into the slot when the threaded sleeve is at multiple angles.

[0016] Preferably, the shape of the knob is specially shaped, and the outer wall of the knob is covered with a rubber sleeve. By setting the shape of the knob to be specially shaped, people can turn the knob more easily and with less effort. The rubber sleeve covered on the outer wall of the knob can increase the friction between people's hands and the knob, thereby effectively preventing people's hands from slipping when turning the knob.
