Description
Technical Field
The utility model belongs to the technical field of mask production equipment, and relates to a mask cloth conveying device.
Background
In the automatic production process of the mask, during the operation procedures such as cutting, punching and the like, continuously drawn mask cloth (strings are not cut) is in an intermittent conveying state, and although the traction power is derived from the rear end of the cloth, the tension of the mask cloth at the front end is uneven due to intermittent action, so that the cloth is wrinkled, misplaced and the like, and the processing quality and the uniformity of a finished product are affected.
Disclosure of Invention
The utility model aims to solve the problems in the prior art and provide a mask cloth conveying device, and the technical problem to be solved by the utility model is how to keep cloth tension in an intermittent traction process.
The aim of the utility model can be achieved by the following technical scheme: the mask cloth conveying device is characterized by comprising a frame, a lower conveying belt and an upper conveying belt, wherein the lower conveying belt and the upper conveying belt are arranged on the frame, the lower conveying belt is pulled by two first driving rollers which are rotationally connected to the frame, the upper conveying belt is pulled by a plurality of second driving rollers which are positioned on the same straight line, the second driving rollers are rotationally connected with a swing arm, the swing arms are mutually parallel, a mounting plate positioned above the upper conveying belt is fixedly arranged on the frame, and the upper ends of the swing arms are hinged to the mounting plate; the upper conveying belt can press the lower conveying belt when the swing arm is in a vertical state.
Further, the middle parts of the swing arms are hinged with a pull rod, a tension spring is connected between the end part of the pull rod and the frame, and the tension spring can drive the upper conveying belt to press the lower conveying belt.
Further, a driving motor is arranged on the frame and drives one of the first driving rollers to rotate.
The cloth conveying device is arranged in front of a cloth traction continuous processing procedure, a driving motor can be selectively arranged according to needs, the lower end of a swing arm is always in a state of inclining to the cloth traction direction, when cloth is conveyed normally, the movement of the cloth can drive the inclination angle of the swing arm to be increased, then the cloth and an upper conveying belt are pressed and loosened, when the cloth is in a traction stop state, a lower conveying belt stops running, the inclination angle of the swing arm is reduced, the upper conveying belt and the lower conveying belt realize the pressing of the cloth, at the moment, although the upper conveying belt still can move, the lower conveying belt presses the cloth with the upper conveying belt, the movement resistance of the cloth is increased and stopped, and the phenomenon that the cloth at the front end of an operation area is loosened, misplaced and deviated due to intermittent traction of the cloth is avoided, so that the cloth maintains the tension force to be constant in the intermittent operation process.
Drawings
Fig. 1 is a schematic structural view of the cloth conveying apparatus.
In the figure, 1, a rack; 2. a lower conveyor belt; 3. an upper conveyor belt; 4. a first driving roller; 5. a second driving roller; 6. swing arms; 7. a mounting plate; 8. a pull rod; 9. a tension spring; 10. and driving the motor.
Detailed Description
The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.
The mask cloth conveying device shown in fig. 1 comprises a frame 1, a lower conveying belt 2 and an upper conveying belt 3 which are arranged on the frame 1, wherein the lower conveying belt 2 is pulled by two first driving rollers 4 which are rotatably connected to the frame 1, a cloth cutting and punching unit is positioned at the outlet position of the lower conveying belt 2 or the position for supporting the lower conveying belt 2, the upper conveying belt 3 is pulled by a plurality of second driving rollers 5 which are positioned on the same straight line, the second driving rollers 5 are rotatably connected with a swinging arm 6, the swinging arms 6 are mutually parallel, a mounting plate 7 positioned above the upper conveying belt is fixedly arranged on the frame 1, and the upper end of each swinging arm 6 is hinged on the mounting plate 7; the upper conveyor belt 3 can press the lower conveyor belt 2 when the swing arm 6 is in the vertical state.
The middle part of each swing arm 6 is hinged with a pull rod 8, a tension spring 9 is connected between the end part of the pull rod 8 and the frame 1, the tension spring 9 is in a compressed state, and the tension spring 9 can drive the upper conveying belt 3 to press the lower conveying belt 2.
When the cloth is required to be independently transmitted, a stepping driving motor 10 can be arranged on the frame 1, the driving motor 10 drives one of the first driving rollers 4 to rotate, the cloth conveying device is arranged in front of the cloth traction continuous processing procedure, the driving motor 10 can be selectively arranged according to the requirement, and when the driving motor 10 is not arranged, the stop of the lower conveying belt 2 is required to be synchronous with the driving power for traction of the movement of the cloth. The lower extreme of swing arm 6 is in the state to cloth traction direction slope all the time, when the cloth normally carries, the inclination of swing arm 6 is increased can be driven in the removal of cloth, and then make and compress tightly between cloth and the upper conveyor belt 3 loosen, when the cloth is in the state of stopping that pulls, lower conveyor belt 2 stops moving, the inclination of swing arm 6 reduces, upper conveyor belt 3 and lower conveyor belt 2 realize compressing tightly to the cloth, at this moment, though still can remove upper conveyor belt 3, lower conveyor belt compresses tightly the cloth with upper conveyor belt 3, the removal resistance of cloth increases and is stopped, avoid because of cloth intermittent type nature pulls and causes cloth relaxation, dislocation and the off tracking of operation area front end, make the cloth maintain the equilibrium of tensioning force at intermittent type in-process of operation.
The specific embodiments described herein are offered by way of example only to illustrate the spirit of the utility model. Those skilled in the art may make various modifications or additions to the described embodiments or substitutions thereof without departing from the spirit of the utility model or exceeding the scope of the utility model as defined in the accompanying claims.
