Flat-clothing machine tool

Abstract

The invention discloses a flat clothing machine tool. The flat clothing machine tool comprises a side clamping device, a jacking device, a cladding and pressing sliding platform device and a cladding and pressing movement device; a base plate is fixedly provided with a fixed supporting beam; a movable supporting beam is parallel to the fixed supporting beam and can move relative to the fixed supporting beam; and a jaw is formed above two beams respectively and is used for clamping a workpiece. A push-pull air cylinder is arranged between the fixed supporting beam and the movable supporting beam; a plurality of jacking air cylinders are arranged in an upper cavity of a door-shaped frame; a stepping motor is fixedly arranged outside a cladding and pressing sliding platform surface, and a gear is driven by the stepping motor to move on a rack; a double-rod air cylinder is fixedly arranged inside the upper end of the cladding and pressing sliding platform surface; and a molding rolling shaft and a molding roller are connected and arranged through a T-shaped groove and a T-shaped sliding block. The machine tool has the advantages that: side clamping force is uniform; the machine tool has high stability and structural rigidity, can realize accurate positioning and fixed-length cladding and pressing, applies pressure uniformly, has a small number of parts, and few faults, and is highin efficiency, low in cost, and fully-automatic; and the structure is easy to adjust, and actions are accurate.

Description

technical field [0001] The invention relates to a flat card clothing machine tool for covering flat card clothing on a flat iron frame in the textile industry. Background technique [0002] The cover card clothing machine tools currently used in the market are covered by four sub-device systems in coordination: [0003] Side pressure clamping device: Use multiple sets of cylinders to push the inclined wedge, and pull the moving plate through the pull rod screw set on the wedge to achieve side clamping of the flat card clothing; [0004] Pressing device: Generally, there are two methods, one is to install multiple cylinders on the rotating arm, after pre-installing the iron frame of the cover plate and the cover card clothing, press and clamp it sideways, and the rotating arm turns 90 degrees , let go of the way to open the travel position of the bag press slide table; the other is to implement the bag press slide table to walk through when the top pressure cylinder is press...

AI Technical Summary

Problems solved by technology

[0008] Disadvantages of the existing side pressure clamping device: the multi-point side clamping adopts the inclined wedge block and uses the pull rod screw to change the direction of action, so it is easy to make the side pressure clamping force uneven during the moving and clamping process of the side pressure clamping plate , resulting in uneven lateral clamping force of the flat card clothing;

[0009] Disadvantages of the existing top-pressing device: the rotating arm method is easy to change the tightness between the iron frame of the cover plate and the card clothing of the cover plate by side pressure after the top pressure is released. In order to allow the pressure-packed slide to walk through under tight conditions, after removing the connecting support of the left and right pressure-packed slides, the pressure-packed slide is very unstable during the linear motion process, and the structural rigidity is poor, which seriously affects the device's ability to operate under the pressure-packed slide. The accuracy of the movement of the pressing roller on the table;

[0010] Disadvantages of the existing pressure-packed sliding table device: the moving speed of the pressure-packed slide table is fixed and cannot be adjusted. Due to the inertia of the motor and the difficulty of adjusting the travel switch, the stop point and return point of the pressure-packed slide table cannot be accurately positioned. , which affects the precise length of the package pressure of the package pressure component on the workpiece;

[0011] Disadvantages of the existing pressure-packing movement device: the direction of the cylinder acting on the pressure-packing rollers depends on the movement of the long square in the square hole seat, and the general machining accuracy is difficult to meet the radial clearance control, which is easy to cause the long square to move in the square hole. There are dead spots or large damping during the movement of the square hole seat, which affects the pressure requirements of the package pressure;

[0012] In addition, on the whole, the existing flat card clothing machine tool has many parts, the adjustment structure is complicated, and it is prone to failure
