[0034] Second belt conveyor 3 includes the second horizontal section 31 below mill 1, and the second lifting section 32 being connected with the second horizontal section 31;The second lifting section 32 is arranged in parallel with the first lifting section 22 and the belts of both are opposite and adhere to each other, and the output end of second lifting section 32 is connected to the first horizontal section 21;

[0035] Third belt conveyor 4 is used to realize the rubber output of circulating rubber mixing mechanism, and its input end is telescopicly fitted between the output end below first horizontal section 21 and the upper side of mill 1;When the input end of third belt conveyor 4 is retracted, it avoids the rubber dropped into mill 1 by first horizontal section 21.

[0036] Through the above scheme, in the process of cyclic rubber mixing, the input end of the third belt conveyor 4 is first moved out from between the output end of the first horizontal section 21 and the top of the open mill 1. Through the cooperation of the first belt conveyor 2 and the second belt conveyor 3, the rubber can be cyclically fed into and out of the open mill 1 according to a set number of times, realizing fully automatic and fixed-number cyclic rubber mixing. When the number of mixing times is reached, the input end of the third belt conveyor 4 is then extended back into the space between the output end of the first horizontal section 21 and the top of the open mill 1, and the mixed rubber is output to the next process to complete the rubber mixing. The mechanical structure of this utility model is compact and the floor space is greatly reduced.

[0037] The following are specific embodiments of the present invention.

[0038] The aforementioned third belt conveyor 4 includes a fixed frame 41, a movable frame 42, a drive device 43, and a belt 44; the fixed frame 41 is fixed relative to the ground; the movable frame 42 is set as the input end of the third belt conveyor 4 and is pivotally connected to the fixed frame 41; the output end of the drive device 43 is connected to the movable frame 42 for transmission, so that the movable frame 42 enters and exits between the lower part of the output end of the first horizontal section 21 and the upper part of the open mill 1; both the fixed frame 41 and the movable frame 42 are provided with a number of rollers for the belt 44 to be wound, the rollers are drive shafts or driven shafts, and the drive shaft is driven by a motor.

[0039] Furthermore, the present invention also includes a suspended bracket 5 for mounting and fixing the frame 41, and the body of the drive device 43 is also mounted on the suspended bracket 5.

[0040] Meanwhile, the aforementioned drive device 43 is a cylinder.

[0041] This utility model also includes a fourth belt conveyor 6; the fourth belt conveyor 6 is used to realize the rubber input of the circulating rubber mixing mechanism, and its output end is located above the first horizontal section 21.

[0042] The rubber mixing rollers 11 of the above-mentioned open mill 1 are equipped with rubber guide plates 7 on both sides above the rubber mixing rollers 11, which are used to guide the rubber into the space between the two rubber mixing rollers 11.

[0043] Furthermore, the upper side of the aforementioned guide plate 7 is pivotally connected to the side of the open mill 1, and its lower side is driven by the guide cylinder 8 to swing, which is used to adjust the guide angle.

[0044] Both sides below the output end of the first horizontal section 21 are pivotally mounted with a swing bracket 9. The swing bracket 9 is equipped with several swing rollers 91, which are driven by the swing cylinder 10 to swing, thereby realizing the angle adjustment of the swing bracket 9.

[0045] In the same production line, several sets of the circulating rubber mixing mechanism of this invention can be designed to be connected to each other to meet the needs of multiple circulating rubber mixing.

[0046] The working principle of this invention is as follows:

[0047] (1) Unrefined rubber is fed into the circulating rubber mixing mechanism through the fourth belt conveyor 6. At this time, the input end of the third belt conveyor 4 exits from the output end of the first horizontal section 21 and the top of the open mill 1. The rubber conveyed by the fourth belt conveyor 6 falls directly into the open mill 1 and is output from the bottom of the open mill 1.

[0048] (2) The rubber falling out of the open mill 1 is sent to the second lifting section 32 by the second horizontal section 31. Since the belt of the second lifting section 32 is in contact with the belt of the first horizontal section 22, the two can tighten and convey the rubber upward until the rubber falls to the first horizontal section 21 and is then sent into the open mill 1 by the first horizontal section 21. Thus, through the cooperation of the first belt conveyor 2 and the second belt conveyor 3, the rubber is cyclically fed into and out of the open mill 1 according to the set number of times, realizing fully automatic, fixed-number cyclic rubber mixing.

[0049] (3) When the preset number of rubber mixing times is reached, the input end of the third belt conveyor 4 extends between the output end of the first horizontal section 21 and the top of the open mill 1. At this time, the rubber output by the first horizontal section 21 will fall onto the third belt conveyor 4, and the mixed rubber will be output to the next process.

[0050] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
