Description

Cutting machine for layering leather

The utility model relates to a kind of Leather Processing Machine, particularly a kind of cutting machine for layering leather.

Cutting machine for layering leather is one of important processing units in leather processing field, uses it, a leather can be split into multilayer (2～4 layers) and required thickness uniformity.The leather thickness that splitting machine cuts is even more, illustrates that the working accuracy of this splitting machine is high more, superior performance.At present, layer structure of cuing open of the cutting machine for layering leather of producing both at home and abroad is as shown in Figure 4 structure formation.Upper feeding roller 2, following feed ring roll 11 and with the rotation of following rubber idler 14 leather are moved forward and contact with annular belt knife, to reach the purpose of leather being cutd open layer.But have the following disadvantages.1, since down the feed ring to roll 11 be for relying on rotation according to knife guiding plate 12 and following rubber idler 14, cooperate with upper feeding roller 2 leather is moved forward, thereby, during the subdivision leather, scurf often minces, and plug rolls between 11 at knife guiding plate 12 and following feed ring, cause epithelial lining to occur digging and hinder phenomenon, leather as shown in Figure 6 digs hinders face 16, causes the upper strata skin to be scrapped or reduces quality grade.2, down the feed ring to roll 11 be to be cascaded by the metal ring more than tens to combine, its structure as shown in Figure 7, the adjacent metal interannular all has certain clearance, can upper and lower mobile purpose to adapt to metal ring.When the subdivision leather, because the feed ring rolls 11 and gives the processed bigger squeeze of leather down, make leather surface stay very dark ring roller marks mark (i.e. Tong Cheng ring roll printing), ring roller marks mark 15 as shown in Figure 5, brought inconvenience for the processing of leather back, leather industry requires to eliminate this ring roll printing one after another, but also is difficult at present reach.3, since down the feed ring roll 11 with knife guiding plate 12 between mutual friction mutually, quickened both damages, shortened work-ing life.4, down rubber idler 14 also because of time feed ring roll 11 rotatablely move and this ring rolls the feed pressure that gives, caused the incised wound of this rubber idler, directly influenced the precision of time rubber idler 14 and the quality of subdivision leather.

The purpose of this utility model is to provide a kind of above deficiency that overcomes, and is simple and reasonable for structure, and the leather thickness that processes is even, and leathering does not have the wound of digging, no impression, mechanical life is long, precision is high cutting machine for layering leather.

The purpose of this utility model reaches by the following technical programs.This cutting machine for layering leather is by annular belt knife 1, upper feeding roller 2, pressure roller 3, lower body 8, shim mechanism 9, upper machine body 10, lower feeding roller, idler pulley, compositions such as the crooked adjustment mechanism of upper feeding roller, its special character is that described lower feeding roller is an elasticity lower feeding roller 7, idler pulley is two rigidity jockey pulleys 6, and they touch mutually with elasticity lower feeding roller 7.

On the bottom bracket at fixing elasticity lower feeding roller 7 two ends, establish the scraper plate 5 that touches mutually with elasticity lower feeding roller 7.

The diameter of elasticity lower feeding roller 7 is 70mm～160mm, and length is 1000mm～3800mm, and the diameter of two rigidity jockey pulleys 6 is 70mm～160mm, and length is 1000mm～3800mm.The dimensional parameters of the dimensional parameters of elasticity lower feeding roller 7 and two rigidity jockey pulleys 6 in described scope, can satisfy the structure properties requirement of splitting machine better.Can on existing splitting machine, directly transform.If their diameter is less than 70mm, its intensity is less, influences their life-span, and is more yielding, if greater than 160mm, according to the size of present splitting machine, installs on lower body 8, and its space is affected.

Because the feed ring rolled 11, following rubber idler pulley 14 and directing plate 12 under the utility model had removed in the prior art.And with elasticity lower feeding roller 7 with replace with its two rigidity jockey pulleys that touch mutually 6, upper feeding roller 2 and elasticity lower feeding roller 7 are directly combined carry out leather and cut open layer, elasticity lower feeding roller 7 can move up and down in cuing open layer work within the specific limits, make it compared with prior art, have simple and reasonable for structurely, do not dig and hinder leather, acyclic roll embossing on the leather, do not have the ring-type Friction mark on the elasticity lower feeding roller 7, operate steadily, dissect the characteristics of leather layer thickness uniformity.Because the elastic contribution between elasticity lower feeding roller 7 and two rigidity jockey pulleys 6 has played the effect that compensates processed leather front and rear part potential difference, has further guaranteed the uniformity consistency of the upper strata Pi Qianhou thickness of subdivision.Thereby can remove existing splitting machine for solving the complicated structure formations such as computer setting device that leather front and rear part potential difference is provided with.Behind design one scraper plate 5, can prevent the leather chip effectively attached on the elasticity lower feeding roller 7, guarantee the cleaning on elasticity lower feeding roller 7 and two rigidity jockey pulleys, 6 surfaces, be beneficial to running between the two.

Below in conjunction with accompanying drawing, provide embodiment of the present utility model, be used for further specifying technical solution.

Embodiment is with reference to figure 1～Fig. 3.The annular belt knife 1 and the driving mechanism thereof of this cutting machine for layering leather, upper feeding roller 2 and driving mechanism, pressure roller 3, lower body 8, shim mechanism 9, upper machine body 10, the crooked adjustment mechanism 13 of upper feeding roller 2, the driving mechanisms of elasticity lower feeding roller 7 etc. are same as the prior art.Improvement part mainly is that leather cuts open a layer structure division.Upper feeding roller 2 is the metal rigidity roller, and elasticity lower feeding roller 7 is made by elastomeric material, and two idler pulleies 6 are the rigidity jockey pulley that metallic substance is made, and their diameter is 80mm, and length is 2000mm.Elasticity lower feeding roller 7, two idler pulleies 6 are fixedlyed connected with bottom bracket by bearing, and this bottom bracket is fixedly connected on the lower body 8, and the two ends of scraper plate 5 also are fixed on this bottom bracket.Principle of work is, earlier by the crooked adjustment mechanism 13 adjustment upper feeding rollers 2 of upper feeding roller 2 and the gap between the elasticity lower feeding roller 7, on starting successively, the driving mechanism of the driving mechanism of lower feeding roller and annular belt knife 1, upper feeding roller 2 and elasticity lower feeding roller 7 are done to rotate in opposite directions, annular belt knife 1 rotates, at this moment, the leather 4 that will be dissectd is put on the worktable and when touching mutually with two feed rollers, leather 4 is last, move forward under the drive of lower feeding roller and cutd open layer by annular belt knife 1, along with moving forward gradually of leather 4, this leather is cutd open layer by annular belt knife 1 gradually, is cutd open layer entirely up to whole leather.In dissecing process, the leather chip that scraper plate 5 will be scattering on the elasticity lower feeding roller 7 sweeps, and collects through the staff to be put in the special-purpose bag, has guaranteed elasticity lower feeding roller 7, the cleaning of two rigidity jockey pulleys, 6 working faces and good behaviour in service.If dissect the second layer, the 3rd layer, the 4th layer etc. again, then repeat above process and get final product.The crooked adjustment mechanism of the upper feeding roller 2 that the utility model is used can utilize the crooked adjustment mechanism of upper feeding roller 2 in the prior art, also can utilize the crooked adjustment mechanism of the utility model structure shown in Figure 1.Back a kind of structure formation of crooked adjustment mechanism, simple in structure, easy to adjust.But no matter adjust structure, all belong to protection domain of the present utility model with the bending of which kind of structure formation.Owing to have elastic acting force between two rigidity jockey pulleys 6 that the utility model is used and the elasticity snub pulley 7.So the adjustment of a leather front and rear part potential difference can be adjusted automatically by the elastic contribution between elasticity lower feeding roller 7 and two rigidity jockey pulleys 6, can computer setting device of the prior art.In a single day computer setting device of the prior art breaks down, and must allow device fabrication producer send someone to overhaul, and causes a few days that stops production to the several months, brings greater loss to leather-making enterprises, and the cost height, operates more numerous.

In like manner, according to the technical solution that the utility model provides, the diameter that can also provide elasticity lower feeding roller 7, two rigidity jockey pulleys 6 is 70mm～160mm (except the 80mm), and length is the embodiment of 1000mm～3800mm (except the 2000mm).Because of principle of work, structure are identical with embodiment 1, just therefore the dimensional parameters difference is no longer carefully stated here.

What need further specify is, the diameter parameters of elasticity lower feeding roller 7 and two rigidity jockey pulleys 6 can be identical also can be inequality.If the diameter 100mm of elasticity lower feeding roller 7 for example, the diameter of two rigidity jockey pulleys 6 can be 100mm, also can be 90mm, can also be 110mm etc., and this can design according to practical situation.
