Description

Technical Field

[0001] This utility model relates to the field of tire mixing production, specifically to a tandem one-step granulation masterbatch addition device. Background Technology

[0002] The development of high-performance tires is receiving increasing attention from the industry. For example, green tires are a key area of ​​investment. These tires often contain high-filler silica formulations. Traditional processes struggle to meet the silanization reaction requirements of such formulations during production. However, the tandem one-stage mixing process can solve this problem, leading to its widespread adoption. Compared to traditional multi-stage mixing processes, the tandem one-stage mixing process uses two internal mixers plus a lower auxiliary open mill unit. The upper internal mixer performs initial mixing, while the lower internal mixer performs constant-temperature mixing, which is beneficial for the silanization reaction. The lower auxiliary open mill unit allows for the addition of final processing reagents from the open mill. Since the final processing chemicals are added from the open mill, and most of these chemicals are mixtures of sulfur, accelerators, and anti-scorching agents, all of which are powdery materials, they are light and easily fly away when added from the open mill, making them inconvenient to add. Therefore, the chemicals used need to be mixed and refined separately with a small amount of rubber and additives according to their type. The resulting granules are called granulation masterbatch. Thus, currently, the chemicals are added to the lower auxiliary open mill unit in the form of granulation masterbatch.

[0003] Currently, when adding granulation masterbatch to the open mill, it is fed into the rubber compound from above through the baffle plate. The addition of the masterbatch cannot be controlled. If the addition of granulation masterbatch is too concentrated, a large amount of masterbatch will be added to one position and cannot be immediately mixed into the rubber compound, resulting in rubber compound breakage and a large amount of broken rubber. The broken rubber, contaminated with impurities, can only be discarded, resulting in cost waste and increased cleaning workload for employees. At the same time, the broken rubber compound can also cause the rollers to have no rubber accumulation, causing the granulation masterbatch to flow out along the gaps between the rollers, resulting in insufficient addition of granulation masterbatch and the quality risk of under-sulfurization.

[0004] Therefore, there is an urgent need to solve the technical problem of excessively concentrated addition of masterbatch in tandem open mill granulation. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a tandem one-stage granulation masterbatch feeding device, the technical solution of which is as follows:

The feeding pipe fitting feeds the granulation masterbatch into the feeding trolley, which moves along a track and unloads the material into the weighing scale above the corresponding open mill. The weighing scale is connected to the storage trough via a descending feeding pipe, and the storage trough is connected to the discharge pipe via a flexible hose. The crank-rocker mechanism includes a housing, a motor, a worm gear, a worm, a crank, a connecting rod, a rocker arm, and a connecting rod. The housing is fixed to the open mill support, the motor is mounted on the side of the housing, the worm is arranged on the output shaft of the motor and meshes with the worm gear, the crank is mounted on the side of the worm gear, one end of the connecting rod is hinged to the crank and the other end is hinged to the rocker arm, and one end of the connecting rod passes through the housing and is hinged to the rocker arm and the other end is hinged to the discharge pipe.

[0007] Furthermore, the feeding pipe fitting is a tee, and there are two feeding trolleys. Each of the two discharge ports of the tee corresponds to one feeding trolley for feeding, and each feeding trolley corresponds to several weighing scales for unloading.

[0008] Furthermore, a butterfly valve is provided below the weighing scale.

[0009] Furthermore, the feeding pipe is equipped with several side-blowing mechanisms from top to bottom.

[0029] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A tandem one-stage granulation masterbatch feeding device, based on the technical solution described in Example 1, wherein the feeding pipe 1 is a tee, and there are two feeding trolleys 2. Each of the two discharge ports of the tee corresponds to one feeding trolley 2 for feeding, and each feeding trolley 2 corresponds to several weighing scales 3 for unloading; a butterfly valve is provided below the weighing scales 3 to better control the timing of feeding. Example 3

[0030] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A tandem one-stage granulation masterbatch feeding device, based on the technical solution described in Example 1, wherein the feeding pipe 4 is provided with several side blowing mechanisms 5 from top to bottom. The side blowing mechanism 5 includes an air supply pipe and a one-way valve at its front end. The air supply pipe is connected to an air source. Under the control of the one-way valve, air can only be blown into the feeding pipe 4 and cannot be blown in reverse. Example 4

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A tandem one-step granulation masterbatch feeding device, based on the technical solution described in Example 1, includes a feeding clamp 6.1 at the upper part of the storage tank 6 to control the material quantity and a vibrator 6.2 at the lower part.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A tandem one-stage granulation masterbatch feeding device, based on the technical solution described in Example 1, includes a first feeding pipe 10 and a second feeding pipe 10.2, each connected to a connecting rod 11.6 of a corresponding crank-rocker mechanism 11.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A tandem one-step granulation masterbatch feeding device, based on the technical solution described in Example 1, wherein the feeding pipe 10 is parallel to the baffle plate 9, and the installation angle of the feeding pipe 10 relative to the ground plane is 45 degrees to facilitate the feeding operation.

[0034] To enable those skilled in the art to better understand this utility model, its basic working principle is briefly described below:

[0035] Based on the information from the open mill, after the granulation masterbatch is weighed, it is conveyed to the feeding trolley 2 through the feeding pipe fitting 1 (i.e., tee). The feeding trolley 2 conveys the masterbatch along the track and stops when it reaches the weighing scale 3 above the corresponding open mill, where the masterbatch is unloaded and stored. When the open mill reaches the time when the masterbatch is added, the butterfly valve below the weighing scale 3 opens, and the masterbatch is conveyed to the storage tank 6 along the feeding pipe 4. The side blowing mechanism 5 of the feeding pipe 4 blows the masterbatch pneumatically at a set time to prevent incomplete addition or sticking of the masterbatch. At the same time, the vibrator 6.2 of the storage tank 6 starts vibrating, the feeding clamp 6.1 opens, and the masterbatch is added along the discharge pipe 10 below. The casing 11.2 is fixed to a support of the open mill with screws. When the granulation masterbatch is added, the motor 11.1 starts, and the worm gear 11.5 rotates at high speed with the motor output shaft. At the same time, the worm gear 11.5 drives the worm wheel 11.4 to rotate at low speed. The worm wheel 11.4 drives the crank 11.3 to perform circular motion. When the crank 11.3 rotates, it pushes the rocker arm 11.7 to swing back and forth through the connecting rod 11.6. The rocker arm 11.7 is connected to the feed pipe 10 through the connecting rod 11.8, thereby driving the feed pipe 10 to perform a cyclical semi-arc trajectory motion. After the granulation masterbatch falls from the feed pipe 10, it lands on the baffle plate 9, and then slides evenly between the two rollers of the open mill and is absorbed by the rubber compound.
