DETAILED DESCRIPTION

[0020] Embodiment 1

[0021] like Figure 1 As shown, a rubber additive mixing equipment proposed by the utility model includes a mixing machine body 1, on which two groups of rollers 101 are arranged, above the two groups of rollers 101 and on the mixing machine body 1, a fixing rod 2 is arranged, on which a cleaning mechanism is arranged, and below the two groups of rollers 101 and on the mixing machine body 1, a receiving tray 5 is arranged.

[0022] It should be noted that the rubber mixer body 1 and the rollers 101 are prior art. The rubber additive raw materials can be processed into sheets by driving two sets of rollers 101 by a motor. The specific structure and principle are recorded in detail in the patent with authorization announcement number CN203739045U and will not be repeated here.

[0023] like Figure 2 and Figure 3 As shown, the cleaning mechanism includes a movable seat 4 which is slidably connected to the fixed rod 2, the top of the movable seat 4 is threadedly connected with a bolt 401, the bottom end of the bolt 401 is abutted against the top of the fixed rod 2, an adjusting rod is provided at the bottom end of the movable seat 4, the bottom end of the adjusting rod is connected with a scraper 404, and two groups of first arc-shaped openings are opened at the bottom end of the scraper 404, and the first arc-shaped openings are adapted to the outer wall of the roller 101.

[0024] Furthermore, the adjusting rod is composed of a telescopic rod 402 and a spring 403 . The telescopic rod 402 connects the movable seat 4 and the scraper 404 . The spring 403 is movably sleeved on the outside of the telescopic rod 402 . The top end of the spring 403 is connected to the movable seat 4 , and the bottom end of the spring 403 is connected to the scraper 404 .

[0025] In this embodiment, the rubber mixer body 1 is started to rotate the two groups of rollers 101 to roll the auxiliary raw materials into sheets, which are collected by the receiving tray 5. When some auxiliary raw materials are stuck to the outer wall of the roller 101 and cannot fall off, the bolt 401 is rotated so that the movable seat 4 is no longer fixedly connected to the fixed rod 2, so that the movable seat 4 can slide horizontally along the fixed rod 2. A handle is provided on the side wall of the scraper 404. The scraper 404 is pressed down by holding the handle so that the telescopic rod 402 and the spring 403 are stretched. At this time, the first arc-shaped opening at the bottom of the scraper 404 is in contact with the outer wall of the roller 101, and the movable seat 4 is slid along the fixed rod 2. The auxiliary raw materials stuck on the outer wall of the roller 101 can be scraped off to avoid interfering with the subsequent processing of the auxiliary raw materials. The handle is released and the scraper 404 is driven to return to its initial position under the elastic recovery action of the spring 403.

[0026] Embodiment 2

[0027] like Figure 1 and Figure 2 As shown, the rubber additive refining equipment proposed by the utility model, compared with the first embodiment, has two groups of limit plates 3 symmetrically arranged on the outer wall of the fixed rod 2, and two groups of second arc-shaped openings are opened at the bottom end of the limit plate 3, and the second arc-shaped openings are slidably connected to the outer wall of the roller 101 to avoid interfering with the rotation of the roller 101.

[0028] Furthermore, both left and right sides of the limiting plate 3 are abutted and connected with rubber seats 301 , and the rubber seats 301 are slidably sleeved on the outer wall of the fixing rod 2 .

[0029] In this embodiment, the two sets of limiting plates 3 are slid along the fixed rod 2 to a suitable position, and the limiting plates 3 are limited on the fixed rod 2 by the rubber seat 301 to avoid displacement interfering with the rotation of the roller 101. The two sets of limiting plates 3 can limit the processing area of ​​the auxiliary raw material on the roller 101 to prevent the auxiliary raw material from falling to the outside of the two sets of rollers 101 before being processed, thereby improving the processing efficiency.

[0030] Embodiment 3

[0031] like Figure 1 , Figure 3 and Figure 4As shown, a rubber additive refining equipment proposed by the utility model, compared with the first embodiment, the inner bottom end of the receiving tray 5 is inclined, a first discharge port 502 is provided on one side wall of the receiving tray 5, the outside of the first discharge port 502 is connected with a guide hopper 7, a second discharge port 701 is provided in the middle of the bottom end of the guide hopper 7, and a receiving frame 8 is placed below the second discharge port 701; a plurality of groups of mounting grooves 501 are sequentially provided along the inclined surface from top to bottom in the interior of the receiving tray 5, a rotating shaft 6 is provided inside the mounting groove 501, a plurality of groups of feeding rollers 601 are provided on the rotating shaft 6, a transmission mechanism 602 is provided between the ends of the plurality of groups of rotating shafts 6, the transmission mechanism 602 is configured as a chain transmission mechanism, and the transmission mechanism 602 is driven to rotate by a motor.

[0032] Furthermore, an anti-skid protrusion is arranged on the outer wall of the feeding roller 601, and the outer wall of the feeding roller 601 protrudes from the mounting groove 501, so as to facilitate pushing the step-by-step raw materials downward when rotating.

[0033] In this embodiment, the auxiliary raw materials rolled into sheets by two groups of rollers 101 fall into the receiving plate 5 and move downward along the inclined surface. The controller starts the motor to drive the transmission mechanism 602 to drive several groups of rotating shafts 6 to rotate. The rotation of the rotating shafts 6 drives the corresponding several groups of feeding rollers 601 to rotate, driving the auxiliary raw materials to move toward the first discharge port 502. The auxiliary raw materials enter the receiving frame 8 through the first discharge port 502 and the second discharge port 701 and are collected centrally.

[0034] Working principle: two sets of limit plates 3 are used to slide horizontally on the fixed rod 2, and the limit plates 3 can be limited on the fixed rod 2 through the corresponding rubber seat 301, so as to limit the auxiliary raw materials relative to the processing area of ​​the roller 101, and prevent the auxiliary raw materials from falling to the outside of the roller 101 before being processed, thereby improving processing efficiency; the arrangement of the movable seat 4, the telescopic rod 402 and the spring 403 facilitates the scraper 404 to slide horizontally along the outer wall of the roller 101, and removes the auxiliary raw materials stuck on the roller 101. The auxiliary raw materials on the outer wall of 101 are scraped off to avoid interfering with the subsequent processing of the auxiliary raw materials, thereby further improving the processing efficiency; the setting of the receiving plate 5 and the guide hopper 7 facilitates the rolling of the sheet-shaped auxiliary raw materials into the receiving frame 8, and the motor drives the transmission mechanism 602 to drive several groups of rotating shafts 6 to rotate, so that several groups of feeding rollers 601 rotate, further accelerating the auxiliary raw materials to enter the receiving frame 8 along the first discharge port 502 for centralized collection, which brings convenience to the collection of the auxiliary raw materials and avoids manual sorting and collection by workers.

[0035] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
