[0029] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1-6 As shown, the utility model provides an extrusion mechanism of a rubber flat plate machine, comprising an extrusion head fixing plate 1 at the top and a cylinder fixing plate 2 at the bottom, a plurality of first springs 5 ​​are arranged between the extrusion head fixing plate 1 and the cylinder fixing plate 2, and the bottom end of the first spring 5 is in contact with the top end of the cylinder fixing plate 2;

[0031] A plurality of storage slots 10 corresponding to the first springs 5 ​​are provided at the bottom end of the extrusion head fixing plate 1, the top end of the first spring 5 extends into the storage slot 10, a limiting plate 7 is provided inside the storage slot 10, the top end of the first spring 5 contacts the bottom end of the limiting plate 7, a slide slot 9 communicating with the outside of the storage slot 10 is provided on the inner wall of the storage slot 10, an external plate 18 is fixed at the outer end of the limiting plate 7, and one end of the external plate 18 extends to the outside of the extrusion head fixing plate 1 through the slide slot 9;

[0032] The outer end of the extrusion head fixing plate 1 is provided with a plurality of adjustment components 6, and the adjustment components 6 correspond to the first spring 5. The adjustment components 6 include a threaded rod 601, and the outer end of the threaded rod 601 is provided with a slide 602 through a threaded sleeve, and one end of the external plate 18 is fixedly connected to the outer end of the slide 602, and both ends of the threaded rod 601 are provided with fixing plates 603 through a rotating shaft, and the fixing plates 603 are fixedly arranged on the outer end of the extrusion head fixing plate 1.

[0033] The first spring 5 is arranged between the extrusion head fixing plate 1 and the cylinder fixing plate 2, the bottom end of the first spring 5 contacts with the top end of the cylinder fixing plate 2, and the top end of the first spring 5 contacts with the bottom end of the limit plate 7, so the distance between the limit plate 7 and the cylinder fixing plate 2 is the length of the first spring 5. In order to adapt to first springs 5 ​​of different sizes, the limit plate 7 can be slid inside the storage groove 10 to adjust the distance between the limit plate 7 and the cylinder fixing plate 2. When adjusting, the threaded rod 601 is rotated, and the slide 602 connected to the threaded rod 601 by threads slides on the threaded rod 601. The slide 602 drives the limit plate 7 to move inside the storage groove 10 through the external plate 18 for adjustment. Since the slide 602 is connected to the threaded rod 601 by threads, when the slide 602 moves to the corresponding position, it will be automatically fixed at the corresponding position of the outer end of the threaded rod 601, and there is no need to fix it in an additional way. The operation steps are more convenient and quick.

[0034] In order to improve the accuracy of adjustment, Figure 2 As shown, the top end of the threaded rod 601 passes through the top fixing plate 603 and is fixed with a knob, and a clamping block 605 is fixed on the side of the slide seat 602 away from the extrusion head fixing plate 1;

[0035] A scale plate 604 is disposed between the two fixing plates 603 . Two ends of the scale plate 604 are fixedly connected to the two fixing plates 603 , respectively. The outer end of the scale plate 604 is embedded in the clamping block 605 .

During the sliding process, the positions of the block 605 and the slide seat 602 can be accurately known through the scale on the scale plate 604, and then the position of the limit plate 7 can be determined, so that all the limit plates 7 can be accurately adjusted to the same position, thereby improving the adjustment accuracy.

[0037] It is necessary to ensure that the extrusion head fixing plate 1 and the cylinder fixing plate 2 move along a straight line, such as Figure 1 , 3 As shown in Figure 6, a plurality of guide rods 8 are provided between the extrusion head fixing plate 1 and the cylinder fixing plate 2. The guide rods 8 correspond to the first springs 5 ​​one by one. The first spring 5 is sleeved on the outer end of the guide rod 8. The bottom end of the guide rod 8 is connected to the cylinder fixing plate 2 by threads and can be easily disassembled.

[0038] The top of the storage slot 10 is provided with a guide hole 3 extending to the top of the extrusion head fixing plate 1, and the top of the guide rod 8 extends through the storage slot 10 to the inside of the guide hole 3;

[0039] The limiting plate 7 is sleeved on the outer end of the guide rod 8. A sealing ring 17 is inlaid on the limiting plate 7. The inner side of the sealing ring 17 contacts the outer end of the guide rod 8. The sealing ring 17 is elastic.

[0040] The extrusion head fixing plate 1 and the cylinder fixing plate 2 are connected in series through the guide rod 8. When the extrusion head fixing plate 1 and the cylinder fixing plate 2 move relative to each other, the extrusion head fixing plate 1 will slide along the guide rod 8, and the limit plate 7 will also slide at the outer end of the guide rod 8.

[0041] The first springs 5 ​​of different sizes have different lengths and overall thicknesses. Figure 1 , 3 As shown in FIGS. 5 and 6 , a pressure chamber 11 is provided inside the guide rod 8, and the top of the pressure chamber 11 extends to the top of the guide rod 8. An air bag 4 is fixedly provided at the outer end of the guide rod 8. The air bag 4 is located between the guide rod 8 and the first spring 5, and can support the first spring 5 from the inside;

[0042] The outer end of the guide rod 8 is provided with an air vent 12 , which is located inside the airbag 4 and can connect the air pressure chamber 11 and the airbag 4 , so that air can flow inside the two.

[0043] After replacing the first spring 5 of a different size, air is inflated into the air pressure chamber 11, and the air flows into the airbag 4 through the air vent 12, so that the airbag 4 expands and contacts the first spring 5 from the inside, thereby supporting the first spring 5 from the inside and preventing the first spring 5 from loosening due to lack of support from the inside.

[0044] When the limit plate 7 slides, the airbag 4 will be squeezed and compressed. Figure 1 , 3 As shown in , 5 and 6, a detachable end plate 13 is provided at the top of the guide rod 8, and an extrusion plug 14 with a rubber pad is provided inside the air pressure chamber 11, and the rubber pad plays a sealing role. The outer ends of the extrusion plug 14 and the rubber pad are in contact with the inner wall of the air pressure chamber 11;

[0045] The extrusion plug 14 is provided with a hose 16 that passes through the extrusion plug 14 and the rubber pad. The top end of the hose 16 extends to the top of the end plate 13. A valve is fixedly provided on the hose 16. A second spring 15 is provided between the extrusion plug 14 and the end plate 13. Both ends of the second spring 15 are fixedly connected to the end plate 13 and the extrusion plug 14 respectively.

[0046] When the limit plate 7 slides along the outer end of the guide rod 8, the sealing ring 17 will squeeze the airbag 4 from top to bottom, and the air inside the airbag 4 will be squeezed and flow into the air pressure chamber 11 through the air vent 12. The air pressure inside the air pressure chamber 11 increases, pushing the squeezing plug 14 to move upward, and the second spring 15 is compressed. When the limit plate 7 moves upward, the airbag 4 is no longer squeezed, and the second spring 15 pushes the squeezing plug 14 to move back, and the air returns to the inside of the airbag 4 through the air vent 12, causing the airbag 4 to rebound again.

[0047] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
