DETAILED DESCRIPTION

[0028] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0029] First embodiment; please refer to Figures 1 to 6The utility model provides a technical solution of a silicone extruder with a pin: it includes a control panel 1 and a support frame 2, a barrel 3 is fixedly installed between the control panel 1 and the support frame 2, and a feed port 4 is embedded on the barrel 3 for injecting silicone raw materials.

[0030] The barrel 3 is fixedly mounted with a mounting ring 5, and the mounting ring 5 is provided with positioning cylinders 10 in evenly spaced circular rings. A fixing block 20 is slidably mounted inside the positioning cylinder 10, and a diverter rod 11 is fixedly mounted on the fixing block 20. When the raw material enters the barrel 3 through the feed port 4 and is driven by the screw thread during the processing, the diverter rod 11 can increase the extrusion pressure and accelerate the mixing speed. This helps compress the material and increase the density of the product.

[0031] And by moving the fixed block 20, the diverter rod 11 will move synchronously, so that the length of the diverter rod 11 inside the barrel 3 changes, and can be adjusted in time as needed.

[0032] A fixing frame 9 is fixedly mounted on the mounting ring 5, and the fixing frame 9 is located at the periphery of the positioning cylinder 10. A lifting plate 15 is slidably mounted on the fixing frame 9, and a mounting plate 19 is fixedly mounted on the lifting plate 15. A fixing block 20 is fixedly mounted on the mounting plate 19, and the fixing block 20 is fixedly connected to the diverter rod 11. By making the lifting plate 15 move up and down, the mounting plate 19 and the fixing block 20 thereon will move synchronously, thereby achieving the effect of changing the length of the diverter rod 11 inside the barrel 3;

[0033] A connecting rod 14 is slidably mounted on the lifting plate 15, and a tooth block 13 is fixedly mounted on the side of the connecting rod 14 away from the lifting plate 15;

[0034] The fixed frame 9 is internally fixed with a tooth plate 12. When the tooth block 13 fits with the tooth plate 12, the tooth block 13 cannot move, and thus the lifting plate 15 cannot move, thereby ensuring the stability of the length adjustment of the diverter rod 11.

[0035] A pressing plate 17 is fixedly mounted on one side of the connecting rod 14 close to the lifting plate 15 . A receiving groove 18 is provided on the pressing plate 17 . Springs 16 are fixedly mounted on the pressing plate 17 at even intervals. The other end of the spring 16 is fixedly mounted on the lifting plate 15 .

[0036] When the extrusion plate 17 is subjected to a force toward the tooth block 13, the connecting rod 14 moves while compressing the spring 16. The movement of the connecting rod 14 causes the tooth block 13 to move, and the tooth block 13 is separated from the tooth plate 12, so that the lifting plate 15 can move, and then the length of the diverter rod 11 can be adjusted.

[0037] The teeth and tooth grooves on the tooth plate 12 and the tooth block 13 can be engaged with each other, so by controlling whether the tooth plate 12 is in contact with the tooth block 13, whether the diverter rod 11 can be adjusted can be controlled.

[0038] The diverter rod 11 passes through the barrel 3 and the mounting ring 5 and is located inside the barrel 3 .

[0039] A fixing plate 6 is fixedly installed between the control console 1 and the support frame 2, and a servo motor 8 is arranged on the fixing plate 6. The shaft output end of the servo motor 8 is fixedly connected to the screw part of the ball screw 21, and a fixing ring 7 is fixedly installed on the nut part of the ball screw 21. When the servo motor 8 is started, the fixing ring 7 can move, thereby adjusting the installation ring 5 at different positions.

[0040] A rotating ring 22 is rotatably mounted on the fixed ring 7. When the rotating ring 22 rotates, it can be dislocated with the fixed frame 9, so that it can move normally.

[0041] A telescopic rod 24 is fixedly mounted on the rotating ring 22 , and a moving ring 25 is fixedly mounted on the telescopic rod 24 . By starting the telescopic rod 24 , a force toward one side of the tooth block 13 can be applied to the extrusion plate 17 .

[0042] Hydraulic rods 26 are evenly and evenly fixedly mounted on the moving ring 25 , and connecting plates 27 are fixedly mounted on the other ends of the hydraulic rods 26 , and slot blocks 28 are fixedly mounted on the connecting plates 27 .

[0043] The number of the slot blocks 28 is the same as the number of the extrusion plates 17 , and the slot blocks 28 are matched with the receiving slots 18 on the extrusion plates 17 .

[0044] At this time, the slot block 28 is inside the accommodating slot 18 , and by controlling the length of the hydraulic rod 26 , the extrusion plate 17 can be lifted and lowered, and the length of the diverter rod 11 inside the barrel 3 can be precisely controlled.

[0045] A control rod 23 is fixedly mounted on the rotating ring 22, and the control rod 23 passes through the fixed ring 7. The fixed ring 7 is provided with a groove for the control rod 23 to slide. The rotating ring 22 can be rotated by the control rod 23, thereby facilitating the moving link.

[0046] Each fixing frame 9 is provided with a slot for the connecting rod 14 to move.

[0047] The cross section of the diverter rod 11 is elliptical, and the short axis of the diverter rod 11 is perpendicular to the ground. The elliptical cross section reduces the contact area between the diverter rod 11 and the flowing rubber during stirring and shearing, thereby reducing the damping force of the diverter rod 11 on the flowing rubber, increasing the extrusion amount of the rubber, and improving the extrusion efficiency of the extruder.

[0048] The working process of the utility model is as follows: firstly, the length of the diverter rod 11 inside the barrel 3 is adjusted according to actual needs.

[0049] The servo motor 8 is started, and the screw portion of the ball screw 21 rotates, so that the fixing ring 7 can move, and when it moves to a position corresponding to the mounting ring 5, it stops moving.

[0050] Since the slot block 28 is matched with the receiving slot 18 on the extrusion plate 17 , the slot block 28 is located inside the receiving slot 18 at this time, and the telescopic rod 24 is started to move the moving ring 25 , thereby applying a force to the extrusion plate 17 toward the tooth block 13 side.

[0051] When the extrusion plate 17 is subjected to a force toward the tooth block 13, the connecting rod 14 moves while the spring 16 is compressed. The movement of the connecting rod 14 causes the tooth block 13 to move, and the tooth block 13 is separated from the tooth plate 12. Then, by controlling the length of the hydraulic rod 26, the extrusion plate 17 can be raised and lowered, and the length of the diverter rod 11 inside the barrel 3 can be accurately controlled.

[0052] When the adjustment is completed, the telescopic rod 24 is reset, that is, the slot block 28 is no longer in contact with the accommodating slot 18. Under the action of the spring 16, the teeth and tooth grooves on the tooth plate 12 and the tooth block 13 can be engaged, and the tooth block 13 cannot move, and the lifting plate 15 cannot move, thereby ensuring the stability of the length adjustment of the diverter rod 11.

[0053] When the adjustment of the diverter rod 11 on a cross section is completed, the rotating ring 22 can be rotated by the operating rod 23 to make it misaligned with the fixed frame 9, and then started and moved to the next position for adjustment.

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
