Description
Technical Field
The invention relates to hot-air non-woven heating equipment, in particular to a hot-air tentering setting machine drying oven with a liftable penetrating heating air suction device, and belongs to the technical field of non-woven equipment.
Background
The hot-air non-woven fabric belongs to one of hot-air bonded (hot-rolled and hot-air) non-woven fabrics, and the hot-air non-woven fabric is a non-woven fabric which is formed by combing fibers into a web, penetrating the web by hot air on drying equipment, and heating the web to bond the web and a product thereof. In through-air bonding, it is common to incorporate a certain proportion of low-melt binder fibers into the web, or to use bicomponent fibers, or to apply a certain amount of bonding powder to the web prior to its entry into the drying chamber by a dusting device. The melting point of the powder is lower than that of the fiber, and the powder is melted quickly after being heated, so that bonding is generated among the fibers. The fiber web made of thermoplastic synthetic fiber can be reinforced by thermal bonding, such as terylene, chinlon, polypropylene fiber and the like commonly used in the production of non-woven fabrics at present. Because fibers such as palm, hemp, wool, cotton, viscose and the like do not have thermoplasticity, a fiber web consisting of the fibers alone cannot be reinforced by heat bonding, but after a certain proportion of thermoplastic fibers are added into the fiber web, the fiber web can be reinforced by adopting a hot air bonding technology.
In through-air bonding, air is the heat carrier and transfers heat to the fibers as the air penetrates the web. Thus, it is first ensured that the hot air is not damaging to the structure of the web during the circulation flow. In the initial stage of the fiber web entering the drying room, the fibers are combined only by cohesive force, and if the introduction mode and the speed of hot air are not proper, the structure of the fiber web is damaged. Secondly, the fiber web must be heated uniformly, so that all properties of the reinforced fiber web are uniform and stable. The temperature deviation of each part should be controlled within the range of +/-1.5 ℃. The common drying equipment is mainly used for drying moisture, the heating temperature is generally low, and the common drying equipment is not suitable for hot air bonding production. In addition, enough heating time of the fiber web is ensured, the low-melting-point fibers of the surface layer and the inner layer of the fiber web are in a molten state to obtain good bonding effect, and the non-woven product cannot be subjected to surface-interior delamination. When the existing flat net heating oven is used for preparing a non-woven fiber product with certain thickness, density and hardness, the drying room can be lengthened to the required length because the fiber net cannot be folded. Therefore, the manufacturing cost is inevitably increased, the land occupation is increased, and the competitiveness of enterprises is influenced. In addition, because the non-woven product has a plurality of fiber components, when the difference of shrinkage rates between fibers is large, or when the difference of hardness required by the front side and the back side is large, wrinkles are generated on the surface of the product after heating and shaping under the condition of relaxation and are difficult to eliminate, and the quality of the product is seriously influenced.

The drying oven further comprises an exhaust mechanism 9 (figure 1) arranged on the oven body, and other gases such as moisture generated in the oven are exhausted through the air outlet 90 and the air duct 91 by the rotation of a fan 92 and an air impeller 93 which are arranged on the top of the oven body.
The concepts related to directionality or directionality in the description of the present embodiment, up, down, left, right, front, and rear, are based on the state shown in fig. 1, and thus should not be construed as limiting the technical aspects of the present invention.
As shown in fig. 2, in the embodiment of the present technical solution, the internal structure of the last two drying ovens among the four drying ovens is changed, and a hot air suction device with a lifting function is installed, and by adjusting the lifting adjusting device nuts 42 on the lifting platforms 41 located on the left and right sides of the drying oven in the advancing direction of the nonwoven fiber web felt, the air suction platform 30 can be lifted and dropped, so that the bidirectional blowing heating of hot air is changed into a unidirectional upward blowing and downward suction manner, and the drying heating of hot air is changed into a penetration heating manner. The other adjusting mode of the lifting platform 41 can adopt a driving mode of a hydraulic cylinder and can also adopt a screw rod and nut structure for adjustment.
As shown in fig. 5, a pair of curtain edge-detecting sensors 56 fixed on the base 55 in the web deviation rectifying device are touch switches, and are electrically controlled and connected by a circuit with an electric control box of the hot air tentering setting machine. The pair of net curtain rectifying roller adjusting devices 57 are air cylinders, are horizontally fixed on the fixed seat in the horizontal direction, and are connected with an air compressor through pipelines. When one side of the net curtain is deviated and touches the edge-detecting sensor 57, the electric control box sends a signal to the air cylinder on the side, and the air cylinder column pops up to push the bearing seat platform 551 provided with the deviation correcting rollers 53 and 54 to move along the bearing seat guide sliding groove 552, so that the deviated net curtain returns to the correct position.
