Description

Structure improved cloth feeding roller power transmission device of papermaking felt needling machine

Technical Field

The utility model belongs to the technical field of non-woven machinery, and particularly relates to a power transmission device of a cloth feeding roller of a papermaking felt needling machine with an improved structure.

Background

The aforementioned papermaking felt is a fabric felt used in the papermaking industry for paper formation and conveyance, and is classified into a wet felt, an upper felt, and a dry felt according to a location on a papermaking machine. The papermaking felt is divided into two types of machine weaving and needle punching, wherein the machine weaving is carried out by adopting wool and nylon short fiber blended yarns and carrying out the working procedures of weaving, felting, fluffing, drying and shaping and the like. The needling is carried out by carding wool and chemical staple fiber such as nylon staple fiber into fiber net, overlapping multiple layers, and needling. The wool roll is a wool net roll. For technical information on papermaking felts, see also patents CN101638860B (papermaking felt and method for making the same), CN107604737B (a moisture-absorbing and air-permeable papermaking felt and method for making the same), CN111806033A (a papermaking press felt) and CN111424459A (a multi-layer composite high pressure-resistant papermaking felt and method for making the same), etc.

Technical information on the papermakmg felt needling machine can be found in CN102011272B (side opening and closing device of endless papermakmg felt needling machine), CN101122068A (endless industrial felt needling machine with four needle zone needling), CN101122069A (endless industrial felt needling machine), CN101122067A (endless industrial felt needling machine), CN102134789B (high speed wide width papermakmg felt needling machine), CN109537170A (novel high efficiency anti-broken needle papermakmg felt needling machine), CN109594202A (high precision needle beam and needle plate mechanism for papermakmg felt needling machine), CN100513663C (endless industrial felt needling machine with four needle zone needling), CN100503932C (endless industrial felt needling machine), CN102031645B (endless papermaking felt needling machine), and CN100503933C (endless industrial needle needling machine), and the like.

The aforesaid needle loom for paper making felt is essentially a combined needle loom for paper making felt, which is a needle punching system comprising a plurality of needle punching machines distributed according to the technological or working procedure requirements and successively implementing needle punching. As is known in the art, papermaking felts are more demanding with respect to felt uniformity and strength, but some unavoidable factors can affect the quality of the papermaking felt and even cause defects or rejects, typically: when the power transmission device, especially the motor, for driving the cloth feeding roller to move is damaged, the main needling motor of the structural system of the needling mechanism is still in a continuous running state, but the base cloth is in a static state due to the stop of the cloth feeding roller, so that the repeated needling of the felting needles at the same position can cause excessive needling to the base cloth, and the quality of the blanket after the blanket is formed at the excessive needling part is seriously influenced and even causes the scrapping. In particular, the aforementioned phenomenon is a technical problem commonly encountered by manufacturers who use felt needling machines for papermaking. Theoretically, when the motor of the power transmission device fails and the cloth feeding roller stops running, a worker can stop the main needling motor by operating the electric control box, but because the needling speed of the needling machine is high, even if the base cloth is found to be static at the first time and the working power supply of the main needling motor is cut off, because of the time difference which cannot be eliminated, excessive needling cannot be effectively eliminated, and the blanket quality can not be saved. In view of the foregoing, there is a need for reasonable improvements, and the solutions described below have been made in this context.

Fig. 4 also shows an upper needling mechanism 7 and a lower needling mechanism 8, which belong to the prior art and are disclosed in patent documents such as CN100503933C, CN100513663C, and CN102134789B mentioned above. In the operating state of the upper and lower needling mechanisms 7, 8, the first power source motor i 41a and the second power source motor ii 41b are also in the operating state, and as described above by the applicant, the feed roll 2 is in the moving state, so that the base cloth 9 wound around (also referred to as "nested") the feed roll 2 is moved in the state shown in fig. 4 (which belongs to the prior art). In this state, the upper nipper 32a and the lower nipper 32b are in a state of being engaged and displaced to nip the feed roller head-rotating support bearing block 211. In the process that the base cloth 9 is driven by the cloth moving roller 2 to move in cycles according to the technological requirements, even if any one of the first power source motor I41 a and the second power source motor II 41b is damaged and cannot work, the structure can still ensure the movement of the cloth moving roller 2, namely, as long as one power source motor is in a good state, the cloth moving roller 2 cannot stop rotating, so that the base cloth 9 cannot stop moving, and the situations that the needle prick damage is excessive, the product quality is damaged, and the product is scrapped are avoided.

When the base fabric 9 is finished being needled to become a felt and needs to be removed, the above-mentioned traveling carriage driving device 33 is operated, the cloth feeding roller traveling carriage 3 is moved, for example, the cloth feeding roller traveling carriage 3 is moved backward in accordance with the position state shown in fig. 3, the cloth feeding roller 2 is also moved backward to a position corresponding to the side surface of the cloth feeding roller support arm 10 shown in fig. 1 and 3, the base fabric 9 (which becomes a felt) is in a loose state, and the upper and lower nipples 32a and 32b are released by the operation of the cylinder provided in the cloth feeding roller traveling carriage 3, that is, the nip 31 is opened. At this time, the cloth feeding roller bracket arm indicated by fig. 3 drives the worm lifter 20 to work, and because the lower end of the screw rod 201 of the cloth feeding roller bracket arm driving worm lifter 20 is connected with the cloth feeding roller bracket arm 10, the screw rod 201 drives the cloth feeding roller bracket arm 10 to correspondingly move upwards when the motor drives the speed reducer to move downwards into the worm lifter case under the drive of the transmission worm. As mentioned above, since the two ends of the cloth feeding roller 2 correspond to the cloth supporting roller supporting arms 10, when the cloth feeding roller supporting arms 10 are displaced upward, the cloth feeding roller 2 is lifted by the cloth feeding roller supporting arms, that is, the cloth feeding roller 2 is swung from the cloth feeding roller moving trolley 3, that is, the cloth feeding roller 2 is transited to the cloth feeding roller supporting arms 10. At this time, the papermaking felt on which needling has been completed is removed as taught by the prior art such as the published patent documents mentioned several times above and particularly in conjunction with the descriptions of CN100503932C (endless industrial woolen needle loom) and CN102031645B (endless papermaking felt needle loom). Then the next base cloth 9 to be needled is arranged, and the cloth feeding roller moving trolley 3 and the cloth feeding roller 2 are in the state shown in figures 3 and 4 again.

In conclusion, the technical scheme provided by the utility model overcomes the defects in the prior art, successfully completes the utility model task and truly realizes the technical effects of the applicant in the technical effect column.
