The tractor comprises a frame, wherein a motor is arranged at the bottom of the frame; a support plate is arranged at the top of the frame; fixing rollers are arranged at the lower part of the support plate; a transmission chain wheel is arranged at one end of each fixing roller; two sides of the upper part of the support plate are provided with a sliding slot respectively, a corresponding movable roller is arranged above each fixing roller, two ends of each movable roller are provided with a sliding block respectively, and each sliding block is clamped into the corresponding sliding slot; and pressing strips are arranged at the top of the support plate, adjusting screw rods are arranged on the pressing strip, the bottom of each adjusting screw rod is connected with the corresponding sliding block after penetrating through the corresponding pressing strip, and the top part of each adjusting screw is above the corresponding pressing strip. According to the utility model, the adjusting screw rod is used for adjusting the upper and lower position of the movable roller, which replaces the traditional hydraulic structure, so that the roll space can be adjusted, the structure is simple, and the cost is low. The tractor is easy to manufacture, and excellent in using effect.
Description
Technical field
The utility model relates to a kind of hauling machine, the adjustable hauling machine of especially a kind of roll spacing.
Background technology
At present, need to use hauling machine in the processing extruding of plastics.Present hauling machine mainly is the roll spacing of controlling hauling machine through the structure of fluid pressure type; But such structure can't be regulated the roll spacing size when using, and roll spacing is fixed usually; Because the extruded product specification tends to change; Therefore the traction effect of stationary roll distance is difficult to be suitable for all products, and if go for the adjustable structure of roll spacing, so just need complicated hydraulic system.So just increased equipment cost greatly.
Summary of the invention
The purpose of the utility model is: provide a kind of roll spacing adjustable hauling machine, it can regulate the use roll spacing of hauling machine, and simple in structure, with low cost, to overcome the deficiency of prior art.
The utility model is achieved in that the hauling machine that roll spacing is adjustable, comprises frame, in the bottom of frame motor is housed; Be provided with supporting plate at frame top; The bottom of supporting plate is provided with stationary roll, is provided with chute in the both sides on supporting plate top, above stationary roll, is provided with corresponding movable roll; Two ends in movable roll are provided with slide block, and slide block snaps in the corresponding chute; Top at supporting plate is provided with press strip, on press strip, is provided with the adjusting screw mandrel, and the bottom of adjusting screw mandrel is passed press strip and is connected with slide block, and the top of regulating screw mandrel is in the press strip top; End at stationary roll is provided with drive sprocket.
Stationary roll and movable roll are 3.Because roller in use often needs repairing, and therefore, all adopts the structure of 3 rollers up and down, can under the situation that guarantees a cylinder dismounting therein, can not influence the carrying out of production yet.
On the adjusting screw mandrel, be connected with handle.Utilize the more convenient use of handle to regulate screw mandrel.
Be provided with the moving axis support at the top of frame, the moving axis support is in the supporting plate both sides, between moving axis support and supporting plate, is provided with power transmission shaft, on power transmission shaft, is provided with the chain regulating wheel.The chain regulating wheel is used for regulating in use the position of chain.
Owing to adopt above-mentioned technical scheme, compared with prior art, the utility model adopts the adjusting screw mandrel to regulate the upper-lower position of movable roll, has substituted the hydraulic structure of transmission, can not only realize using the adjusting of roll spacing, and simple in structure, with low cost.The utility model is made easily, and result of use is good.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
The specific embodiment
The embodiment of the utility model: the structure of the hauling machine that roll spacing is adjustable is as shown in Figure 1; Comprise frame 1, motor 2 is housed, be provided with supporting plate 3 at frame 1 top in the bottom of frame 1; The bottom of supporting plate 3 is provided with 3 stationary rolls 4, is provided with drive sprocket 9 at an end of stationary roll 4; Both sides on supporting plate 3 tops are provided with chute 14, above stationary roll 4, are provided with the movable roll 5 of 3 correspondences, are provided with slide block 6 at the two ends of movable roll 5, and slide block 6 snaps in the corresponding chute 14; Be provided with press strip 7 at the top of supporting plate 3, on press strip 7, be provided with and regulate screw mandrel 8, the bottom of adjusting screw mandrel 8 is passed press strip 7 and is connected with slide block 6, and the top of regulating screw mandrel 8 is in press strip 7 tops; On adjusting screw mandrel 8, be connected with handle 10; Be provided with moving axis support 11 at the top of frame 1, moving axis support 11 is in supporting plate 3 both sides, between moving axis support 11 and supporting plate 3, is provided with power transmission shaft 12, on power transmission shaft 12, is provided with chain regulating wheel 13.
In use; Chain is installed on the output shaft of motor 2, and walk around chain regulating wheel 13 and drive sprocket 9, operating personnel drive through turning handle 10 and regulate screw mandrel 8; Control slide block 6 goes up and down in chute 14, thereby realizes regulating the purpose of stationary roll 4 and movable roll 5 spacings.Stop because adjusting screw mandrel 8 can turn to the optional position, therefore can obtain different roll spacings as required, and need not use hydraulic structure, not only simple in structure, and also with low cost.
