Abstract

The utility model relates to a roller gap adjustment positioning device which can be installed among bearing seats which are arranged at both ends of an upper and a lower rollers of a metal band feeder. The utility model is composed of a base, a stud, and fastening round nuts. When a feeder is operated, axes of rollers can always in a parallel state through height regulation of the utility model, a roller gap is free from influences of external factors, such as cylinder pressure, or oil cylinder pressure, and metal band materials are effectively prevented from deviation.

Description

The roll gap that is used for the band feeder is adjusted registration device

The utility model belongs to the metal-working plant technical field, relates to a kind of roll gap adjustment registration device that the band feeder prevents the band sideslip that is used on shear line or metal plate and belt manufacturing line.

The band feeder is the equipment that often uses in the metal plate and belt manufacturing line of shear line or other high-speed cruising.The structure of traditional feeder is referring to shown in Figure 2, its critical part comprises base 1, left frame 2, rubber covered roll or steel rider assembling 3 down, goes up rubber covered roll or steel rider assembling 4, right frame 5, joint 7, lift cylinder or oil cylinder 8 etc., lower roll 3 is fixed on the frame of the left and right sides, during work, top roll drives by cylinder or oil cylinder 8 and lifts, band steel toe portion enters the feeder exhaust hood or oil cylinder is depressed, and driving device begins to rotate simultaneously, enters the feeding mode of operation.The problem that the feeder of this structure exists at work is: because the fluctuation of cylinder or oil cylinder operation pressure has caused the pressure of roller two ends cylinder or oil cylinder unequal, so just will cause that roller axis tilts, make roller two ends roll gap inequality and roller two ends flatten the degree difference, and then roller diameter inequality when causing machine works, linear velocity produces difference, will inevitably cause being pinched band generation deviation phenomenon at last, in case and deviation phenomenon appears in band, unit can not normally move.

The axis unparalleled phenomenon provided a kind of simple in structure and easy to operate roll gap that is used for the band feeder to adjust registration device when the purpose of this utility model was to the down roller work that exists in the correction prior art.

The technical solution that adopts is so for achieving the above object: the roll gap that is provided is adjusted registration device and is had a base that can be installed on the band feeder one side frame step and have inner bolt hole, thread cartridge has a double-screw bolt on base, is set with a fastening circular nut on double-screw bolt top.During use, two same roll gap are adjusted registration device to be installed in respectively between the bearing seat at feeder down roller two ends, adjust this height of devices by the rotation double-screw bolt, can guarantee roller axis be roller be mechanical positioning at work the time remain parastate, make roll gap not be subjected to the influence of external factors such as cylinder or oil cylinder working-pressure, the deflection uniformity of roller in whole flattening scope so just can prevent the generation of band deviation phenomenon effectively; By adjusting this height of devices, also can make the deflection of roller reach value given in advance simultaneously, avoid the wearing and tearing and the destruction of the excessive pair of rollers of deflection.

The utility model is described in further detail below with reference to accompanying drawing.

Fig. 1 adjusts the structural representation of registration device embodiment for this roll gap.

Fig. 2 uses the front view of scheme drawing for the utility model.

Referring to accompanying drawing, roll gap described in the utility model is adjusted registration device 6, and base 61, lower thread on the step is inserted into the double-screw bolt 63 in the base and the fastening circular nut 62 that is sleeved on the double-screw bolt is formed by being fixed on, this device 6 is provided with the position as shown in Figure 2 in feeder, be located at respectively between the feeder up-down rollers two end axles bearing.In the work structuring of band feeder, the computing formula of spacing is between the metal (upper seat

H=(D ₁/ 2-h ₁)+(D ₂/ 2-h ₂)+T-δ ₁-δ ₂(1) digital code h is a distance between the bearing seat in the formula; h ₁Be the top chock height of center; h ₂Be the step height of center; D ₁Be last roller diameter; D ₂Be following roller diameter; T is a belt steel thickness; δ ₁Be last rolls deformation amount given value; δ ₂For going up the rolls deformation amount given value down.In the practical application, calculate distance h between the bearing seat according to formula (1), rotation double-screw bolt height is adjusted to the desired consistent position of h with up-down rollers bearings at both ends distance between seats, fix with fastening circular nut again, thus the adjustment and the location of realizing the up-down rollers parallelism.

Claims

A kind of roll gap that is used for the band sorting machine is adjusted registration device, it is characterized in that having a base (61) that can be installed on the band feeder one side frame step and have inner bolt hole, going up thread cartridge at base (61) has a double-screw bolt (63), is set with a fastening circular nut (62) on double-screw bolt (63) top.
