Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1-3 The utility model provides a technical solution: a tension adjustment device for a roving machine, comprising: a bottom plate 1, a first guide groove 2, a first slider 3, a connecting plate 4, a push rod 5, a second guide groove 6, a second slider 7, a hoop 8, a spring 9, a baffle 10, a dust cover 11, a slide groove 12 and a fastening screw 13;
[0024] A bottom plate 1, a first guide groove 2 is provided on the top of the bottom plate 1, and a first slider 3 is provided inside the first guide groove 2, a connecting plate 4 is connected to the outside of the first slider 3, and a push rod 5 is connected to the outer end of the connecting plate 4, a second guide groove 6 is provided on the top of the first slider 3, and a second slider 7 is provided inside the second guide groove 6, a spring 9 is connected to the outside of the second slider 7, and the outer end of the spring 9 is fixedly connected to the bottom plate 1, a hoop 8 is provided above the second slider 7, and a baffle 10 is connected to the bottom of the hoop 8;
[0025] The dust cover 11 is arranged above the base plate 1 , and the dust cover 11 is fixedly connected to the base plate 1 by fastening screws 13 , and a sliding groove 12 is provided on the top of the dust cover 11 .
[0026] like Figure 1 and Figure 2 The middle bottom plate 1 is arranged in a "concave" type structure, and the first guide grooves 2 are arranged at equal intervals on the front and rear sides of the bottom plate 1, and the first guide grooves 2 on the front and rear sides are arranged alternately, which is convenient for the setting of the first slider 3. The first slider 3 and the first guide groove 2 constitute a sliding structure, and the first slider 3 monomers are integrally arranged through the connecting plate 4, which is convenient for multiple first sliders 3 to move synchronously. The outer end of the push rod 5 passes through the outer side of the bottom plate 1, and the push rod 5 and the bottom plate 1 constitute a sliding structure, which is convenient for squeezing the connecting plate 4 to slide, and the second slider 7 and the second guide groove 6 constitute a sliding structure, which is convenient for the spring 9 to pull the second slider 7.
[0027] like Figure 1 and Figure 3 Slide grooves 12 are provided at equal intervals on the middle dust cover 11, and the slide grooves 12 are arranged one-to-one corresponding to the hoop 8, which is convenient for the use of the hoop 8. The hoop 8 is slidably and sealedly connected to the slide grooves 12 through the baffle 10 to prevent dust from entering the bottom plate 1 through the slide grooves 12.
[0028] Working principle: When using the tension adjustment device for roving frame, Figure 2As shown, by squeezing the push rods 5 on the front and rear sides, the push rods 5 push the connecting plate 4 to slide, so that the first slider 3 slides on the bottom plate 1 through the first guide groove 2. When the first slider 3 slides, the outer side of the first slider 3 squeezes the second slider 7, so that the second slider 7 moves with the first slider 3, thereby driving the hoop 8 to move, so that the hoop 8 on the front and rear sides is distributed in a straight line, which is convenient for the roving to penetrate. After the roving penetrates, the push rod 5 is released to reset the hoop 8, so that the roving is wavy;
[0029] When the roving is subjected to tension, Figure 1 As shown, the roving pulling hoop 8 slides on the dust cover 11. When the hoop 8 slides, it pulls the spring 9 through the second slider 7, so that the hoops 8 on the front and rear sides are close to each other to offset the pulling force of the roving. When the roving is relaxed, the pulling force of the spring 9 can be used to make the hoops 8 on the front and rear sides move away from each other, so that the roving is tightened and stressed, thereby adjusting the roving tension. This is the entire working process of the tension adjustment device for the roving machine.
