Problems solved by technology

Its weak point is: 1, see image 3 As shown, the sliding arm B3 is directly fixedly connected to B41 of the control slider B4, so that the angle of the scraper B1 cannot be directly adjusted. If the angle is required, the screw B5 must be loosened to remove the scraper B1 from the scraper holder B2, and then, Then grind the scraper B1 to an angle on the abrasive belt before using it. This method is time-consuming and laborious.
2. Often the grinding angle cannot achieve the desired effect, and cannot adapt to the requirements of different printing and dyeing varieties for the tightness of the scraper, which cannot guarantee the quality of printing and dyeing
3. In the printing process, it has always been a major problem affecting the printing effect

Embodiment 1

[0027] Example 1, see Figure 4~6 , the flat screen printing machine printing and dyeing mechanism angle adjustable scraper device, the scraper 1 is fixedly connected to the scraper frame 2, the scraper frame 2 is fixedly connected to the sliding arm 3, the sliding arm 3 is fixedly installed on the sliding arm seat 4, and the control slider 5 is fixedly connected with an adjusting disc 6, and an arc-shaped T-slot guide rail 62 is formed on the adjusting disc 6, and a T-shaped guide post 41 is provided on the corresponding slide arm seat 4, and the T-shaped guide post 41 is inserted into the arc-shaped T-slot In the guide rail 62 , a bayonet 61 is formed on the adjusting disk 6 , the spring positioning pin 7 is fixedly installed on the folded portion 42 on the slide arm seat 4 , and the latch 71 of the spring positioning pin 7 is locked in the bayonet 61 .

[0028] The bayonet socket 61 on the described adjusting disc 6 is divided into three scales, one at 15 degrees.

Embodiment 2

[0033] Example 2, see Figure 7-11 , the adjusting disc 6 is composed of three plates, the plate 6a with the bayonet and the two plates 6b, 6c are fixedly connected together with screws 63, the two plates 6b, 6c are connected with the groove 6a1 on the plate 6a with the bayonet 61 An arc-shaped T-slot guide rail 62 is formed. This is more conducive to the installation of the present invention.

[0034] Working principle: pull up the pin 71, directly pull the sliding arm 3 to adjust to the angle to be used, then put down the pin 71, the pin 71 is directly inserted into the bayonet 61, and the required printing effect can be achieved without replacing any spare parts, which is very convenient.

[0035] Under the condition of the same height adjustment, the pressure of the scraper 1 is increased, and the effect is very obvious in the case of light and fine patterns and large surface patterns that require a large scraper pressure. It breaks through the traditional printing machi...

Abstract

The invention relates to an angle-adjustable scraper device for a printing and dyeing mechanism of a flat screen printing machine. A scraper is fixedly connected with a scraper holder, the scraper holder is fixedly connected with a slide arm, the slide arm is fixedly arranged on a slide arm base, a control slide block is fixedly connected with an adjusting disc, an arc T-shaped groove guide rail is formed on the adjusting disc, the corresponding slide arm base is provided with a T-shaped guide post, and the T-shaped guide post is plugged in the arc T-shaped groove guide rail; and a bayonet is formed on the adjusting disc, a spring positioning pin is fixedly arranged on a turned-up part of the slide arm base, and a plug pin of the spring positioning pin is blocked in the bayonet. The angle-adjustable scraper device breaks through the defects that the conventional calico printing machine cannot adjust the angle of the scraper directly and has light printing colors, and is quite convenient to operate.

Description

Technical field: [0001] The invention relates to the technical field of printing and dyeing machinery, in particular to a scraper device with adjustable angle of the printing and dyeing mechanism of a flat screen printing machine. Background technique: [0002] like figure 1 , 2 As shown, the scraper B1 in the printing and dyeing mechanism B of the traditional printing machine A is fixed directly on the scraper frame B2, the scraper frame B2 is fixedly connected to the sliding arm B3, and the sliding arm B3 is fixedly connected to the control slider B4. When working, the stroke and speed of the scraper B1 can be adjusted and controlled through the Chinese screen, that is, the stroke and speed of the scraper can be adjusted by adjusting the stroke and speed of the control slider B4. Its weak point is: 1, see image 3 As shown, the sliding arm B3 is directly fixedly connected to B41 of the control slider B4, so that the angle of the scraper B1 cannot be directly adjusted. I...
