Description

Feeding assembly of edge rolling machine

Technical Field

The invention relates to the technical field of washing machine roller rounding, in particular to a feeding assembly of a rounding machine.

Background

The rolling machine is a common device used for rolling and bending the washing machine drum in the washing machine drum processing technology, the common rolling machine is a three-roller rolling machine, the principle of the rolling machine is that after a plate-shaped drum enters between pressure rollers, the rolling machine can be continuously extruded and bent, the three-roller rolling machine is provided with a feed inlet and a discharge outlet, the rolling machine enters the plate-shaped drum between the pressure rollers from the feed inlet, and the rolling machine leaves the cylindrical drum between the pressure rollers from the discharge outlet.

At present, the structure of a three-roller type edge rolling machine mainly comprises a power part, a nip roll and a conveyer belt, wherein under the action of the power part, the nip roll rotates, the conveyer belt moves and conveys a roller material with a plate shape on the upper part to a feed port between the nip rolls, so that the processes of automatic feeding, bending and discharging are realized; however, the practical application finds that, because the drum of the washing machine is difficult to form into a standard plate shape after being processed in the previous process, the mesh structure in the middle of the drum of the washing machine is in an upward arched state before entering the three-roller type rounding machine under most conditions, when the drum of the washing machine is conveyed on the conveying belt, two sides of the drum of the washing machine directly fall on the conveying belt, and the mesh structure in the middle of the drum of the washing machine is not directly contacted with the conveying belt, however, the distance between the pressure rollers in the three-roller type rounding machine is calibrated and fixed during the operation of the equipment, therefore, the arched mesh part on the drum of the washing machine is difficult to directly and effectively enter between the pressure rollers at the position of the feed port, which greatly affects the work efficiency of the whole washing machine drum production line, the common processing method is that a worker needs to take care of one side, when the plate-shaped material of the washing machine is about to enter the feed port of the rounding machine, in this way, the worker presses the arching portion with both hands down to make effective feeding, mainly with the following drawbacks:

(1) from the safety perspective, when the arched part of the roller is manually pressed downwards, the roller moves towards the feeding hole along with conveying, and once the manual gravity center is unstable, the roller has the potential safety hazard of falling or plugging the hands into the feeding hole of the rolling machine;

(2) in consideration of production cost, at least one worker is needed to attend when the equipment runs, so that the production cost is increased, and the arched part is pressed down by both hands of a worker, so that the effect is unstable, the hidden trouble of difficult feeding still exists, and the production efficiency is reduced;

(3) in consideration of processing precision, the subsequent drum quality is directly influenced by the drum rounding effect of the washing machine, manual pressing by workers is relied on, the force path and the force application direction are uncertain, and once the drum is deviated or locally deformed during feeding, the quality of a finished product is directly influenced;

therefore, there is a need for an improved edge rolling machine that solves the above-mentioned problems.

Referring to fig. 9, a third slide way 93 which is horizontally distributed extends forwards from the bottom end of the second slide way 92, the third slide way 93 can be matched with the bottom of the first slide way 91 to fix the nip roll 8, namely, the material pressing roller 8 can not generate displacement when pressing the material position, can better flatten the arched part on the roller material, and improve the flattening efficiency and stability, see fig. 10, a spring four 15 is fixed between one end of the transmission rod 111 and the guide plate 3, the spring four 15 utilizes the self elasticity to make the transmission rod 111 in a stable state when not pushed by the material pushing plate 6, and further, the slide rail 10 is kept in a stable state when the nip roll 8 is at the nip position, so that the slide way four and the slide way one 91 are better matched and the position of the nip roll 8 is fixed, specifically, the spring sleeve 20 is fixed on the guide plate 3, one end of the transmission rod 111 is inserted into the spring sleeve 20, and two ends of the spring four 15 are respectively fixed between the end of the transmission rod 111 and the spring sleeve 20.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which fall within the scope of the invention as claimed.
