A kind of synthetic leather meter-measuring device
Technical field
This utility model belongs to leather manufacture technical field, is specifically related to a kind of synthetic leather meter-measuring device.
Background technology
Current PU synthetic leather wet process technique flow process is by base material once through dip-coating, blade coating, solidification, washing, then uses circulating heat conduction oil to obtain finished product by drying.After obtaining finished product, also by further for the demand according to client bundling.Common customer counts by rice, the meter-measuring device adopted at present is by filling a race code device above a roller rotated, race code device rotates on the synthetic leather of unsettled operation and counts, and presses roller turn motor switch by hand when metering quantity arrives, thus stopping metering process.Then by manually cutting off synthetic leather, after taking out the leather spooled, then count next time.Easily skid on unsettled synthetic leather owing to running code device, therefore can not accurately carry out the metering of synthetic leather, so being badly in need of developing a set of more efficient meter-measuring device.
Summary of the invention
Being in that the defect and the deficiency that exist for prior art, the purpose of this utility model is in that to provide a kind of synthetic leather meter-measuring device, and this device can effectively solve the problem that the metering that conventional synthesis leather factory runs into when bundling metering is inaccurate, the inefficient problem of metering bundling.
For achieving the above object, this utility model is by the following technical solutions:
A kind of synthetic leather meter-measuring device, including support, both sides on described support are respectively arranged with count roll and rewind roll, the side that support is relative with rewind roll is configured with the leather roll support for placing leather volume, being provided with the rotary encoder for counting on described count roll, count roll is provided above the cutter sweep for cutting synthetic leather;Described count roll is connected with the outfan of count roll motor, and described rewind roll is connected with the outfan of rewind roll motor;The leather volume motor rotated with count roll motor in synchrony it is provided with bottom described leather roll support;The output shaft of described leather volume motor is connected with leather volume rotating shaft.
Further, described support being provided with compression support, described compression support is provided with the hold-down roller matched with nickstick, hold-down roller is connected with pneumatic fitting;Described pneumatic fitting includes interconnective hold down gag and cylinder;Described cylinder controls to be connected with hold-down roller.
Further, described cutter sweep be fixed on compression support lower surface, including straight line square guide rail and match with straight line square guide rail with cutting pocket knife slide block.
Further, described support is arranged below flat board, and described leather volume motor, count roll motor and rewind roll motor are fixed on flat board.
Further, the height of described count roll is arranged higher than rewind roll.
Compared with prior art, this utility model has following useful technique effect: this device is by drawing the synthetic leather of bundling to be counted to count roll, counted by the rotary encoder arranged on count roll, drawn by the synthetic leather of count roll and carry out rewinding to rewind roll, stop rewinding when counting reaches desired value, and utilize cutting pocket knife to be cut off by synthetic leather.This device efficiently solves the problem that there is error of meter counter in metering bundling when conventional synthesis leather produces, it is possible to realize the metering to synthetic leather rice number accurately and rapidly.At the uniform velocity operate by arranging leather winding up roller motor, count roll motor and rewind roll driven by motor leather volume, count roll and rewind roll, it is to avoid synthetic leather skids and sideslip on roller, makes counting accurate, and does not need artificial during this device busy, is effectively improved counting efficiency.
Further, by arranging hold-down roller and pneumatic fitting, effectively prevent synthetic leather from the phenomenons such as skidding or relaxes occurring on count roll, it is ensured that the accuracy of counting.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Referring to Fig. 1, this utility model includes support 9, count roll 5 and rewind roll 6, nickstick 5 and rewind roll 6 and is separately positioned on the both sides on support 9;Side on described count roll 5 is provided with the rotary encoder 10 for counting;Described count roll 5 is connected with the outfan of count roll motor 8, and described rewind roll 6 is connected with the outfan of rewind roll motor 8.
On support 9, count roll be provided above compress support, the platform of described compression support is provided with the hold-down roller 2 matched with nickstick 5;Compressing and be additionally provided with hold down gag 4 on the platform of support, described hold down gag 4 controls to be connected with hold-down roller 2 by cylinder 3.Compress rack platform lower surface, nickstick 5 is provided above the cutter sweep 11 for cutting synthetic leather, referring to Fig. 2, cutter sweep 11 includes straight line square guide rail 14 and the cutting pocket knife 13 that can slide on straight line square guide rail 14, and cutting pocket knife 13 is provided on the slide block that straight line square guide rail 14 casees coordinates.Support is arranged below flat board, and described count roll motor 8 and rewind roll motor 7 are fixed on flat board.The height of count roll 5 is arranged higher than rewind roll 6.
The side relative with rewind roll 6 of support 9 is additionally provided with the leather roll support 15 for placing leather volume 1, is provided with the leather volume motor 12 with count roll motor 8 synchronous axial system bottom leather roll support 15;The output shaft of described leather volume motor 12 is connected with leather volume 1 rotating shaft.
During work, the synthetic leather of bundling to be counted is drawn on count roll 5.Count roll is compressed by hold-down roller 2, when necessary, in order to be better protected from skidding can on count roll encapsulated.Pressure between count roll and synthetic leather can pass through hold-down roller and be adjusted by the hold down gag 4 on hold-down roller.Count roll is driven by count roll motor 8 and rotates, and leather volume 1 rotates under leather volume motor 12 drives;Count roll motor 8 can synchronous axial system with leather volume motor 12.When there being certain rotating speed, synthetic leather tension force drive rotation with it by count roll.Same, rewind roll starts to rotate under the drive of rewind roll motor 7, is driven it with rotation from synthetic leather tension force by count roll when there being certain rotating speed, and the synthetic leather that synthetic leather licks completes rewinding in rewind roll.In the process of rewinding, the rotation of count roll is rotated encoder 10, makes rotary encoder output frequency signal, this frequency signal is gathered by high-speed counter and counts, through counting after a while, when count value reaches desired value, stop rewinding, use cutting pocket knife to be cut off by leather.
When synthetic leather rice number reaches desired value, cutter sweep is used to cut off.Cutting pocket knife is fixed on slide block so that it is move reciprocatingly on line slideway under the effect of driving device (motor or cylinder).
