Description

Technical Field

[0001] This utility model relates to the field of rubber product technology, and in particular to an automated foaming and feeding production line. Background Technology

[0002] In existing technologies, rubber compounding production lines typically include internal mixers, elevators, multiple single-layer open mills, and sheeting machines. In actual production, the multiple single-layer open mills are usually arranged in a straight line. The internally mixed rubber compound is conveyed by the elevator to the first single-layer open mill for initial mixing, and then sequentially passed through multiple subsequent single-layer open mills for segmented rolling, and finally conveyed to the sheeting machine for sheeting.

[0003] However, the aforementioned traditional open mixing production line has the following shortcomings: Due to the use of multiple single-layer open mixing mills arranged in a straight line, the equipment occupies a large area, resulting in low plant space utilization and high overall energy consumption, leading to high electricity costs. Furthermore, during the mixing process, the edge material of the rubber compound usually needs to be manually cut and recycled and then fed back into the open mixing mill, resulting in low automation, high labor intensity, and potential operational safety hazards. In addition, to achieve multiple rolling effects, a larger number of open mixing mills are often required, increasing equipment investment and maintenance costs. Moreover, in the aforementioned traditional process, to improve the dispersion and thickness uniformity of the rubber compound, it is usually necessary to manually turn and fold the rubber compound on the open mixing mill rollers, forming a so-called triangular bale operation. This process is not only labor-intensive and inefficient, but also highly dependent on the operator's experience, easily leading to unstable mixing quality. Utility Model Content

Beneficial effects

[0016] Compared with the prior art, the present invention has at least the following advantages:

[0017] 1. This utility model integrates the functions that traditionally require multiple single-layer open mills into one device by using a double-layer roller assembly of a double-layer open mill to double-press the rubber compound. The structure is compact, significantly reducing the number of devices and the length of the entire line, effectively reducing the area occupied by the equipment and the space required for the factory, while also reducing the power consumption of the entire line, the equipment investment cost, and the number of operators.

[0018] 2. This utility model of a double-layer open mill achieves automatic cutting and automatic recycling of edge material by setting an edge material recovery mechanism between the upper and lower roller groups and combining it with a cutting mechanism. This reduces manual intervention, improves the level of production automation, and reduces labor intensity and operational safety risks.

[0019] 3. This utility model uses a mobile conveying mechanism set at the bottom of the double-layer open mill to transport the rolled material to the lifting device, and then the lifting device feeds it into the feed hopper of the double-layer open mill. The mobile conveying mechanism, the lifting device and the feed hopper work together to form a circulating material conveying path, so that the rubber compound can enter the double-layer open mill multiple times for multiple rolls, which significantly improves the mixing uniformity and product quality stability.

[0020] 4. The material mixing mechanism of this utility model reciprocates by pushing and pulling the rubber sheets between the upper roller group and the lower roller group, replacing the traditional manual operation of folding triangular bags, reducing the intensity of manual labor, and improving the automation level of rubber turning and mixing and the stability of mixing quality.

[0021] 5. The scraper of the scraping mechanism of this utility model is driven by the scraping telescopic rod to closely adhere to the surface of the upper and lower rollers, remove the residual adhesive material adhering to the roller surface, and ensure the cleanliness of the roller surface.

[0022] 6. In the rolling process of this utility model, the upper baffle mechanism and the lower baffle mechanism respectively limit the rubber material in the width direction. The upper baffle mechanism can adjust the distance between the two upper baffle plates through the displacement telescopic rod to accommodate rubber materials of different widths, while the lower baffle mechanism drives the lower baffle plate to flip up through the flip-plate telescopic rod to facilitate cleaning and maintenance of the lower baffle plate.

[0044] The upper roller group 3 includes two upper rollers arranged in parallel, and the lower roller group 2 includes two lower rollers arranged in parallel. The rotating shafts of the upper rollers and the lower rollers are respectively connected to the output end of the reducer 15 through a universal drive shaft 16.

Two cutter mounting arms 171 are fixed to the connecting shaft 170, and the cutters 172 are rotatably connected to the ends of the cutter mounting arms 171. The counterweight 173 is used to drive the connecting shaft 170 to rotate under gravity, causing the cutters 172 to fit against the lower region of the circumferential surface of the lower roller. The cutters 172 are used to cut off the side edges of the film conveyed from the lower roller assembly 2 to the film output machine 500, making the side edges of the film neat.

[0047] like Figure 8As shown, the upper baffle mechanism 6 includes an upper fixed plate 60 fixed to the top of the frame 1. Two parallel guide cylinders 61 are fixedly connected to both sides of the upper fixed plate 60. A telescopic seat 62 fixed to the top of the upper fixed plate 60 is connected between the two guide cylinders 61. A displacement telescopic rod 63 is installed on the outer side of the telescopic seat 62. The output shaft of the displacement telescopic rod 63 passes through the telescopic seat 62 and is connected to a vertically arranged upper fixed seat 65. An upper baffle plate 66 is installed on the inner side of the upper fixed seat 65. A guide column 64 is movably inserted through the guide cylinder 61.

The inner side of the guide rod 931 forms an edge material guide surface, causing the edge material to concentrate inward during the process of being conveyed to the first recycling roller 91 and the second recycling roller 92, preventing the edge material from deviating outward, and passing around the top of the first recycling roller 91 and the second recycling roller 92 in sequence. Driven by the recycling drive motor 97, the first recycling roller 91 and the second recycling roller 92 rotate towards the side close to the rolling gap of the lower roller group 2, guiding the edge material to the rolling gap of the lower roller group 2 for recycling and rolling.

Two guide rods 74 also movably pass through the crossbeam 72. The guide rods 74 are arranged parallel to the material feeding telescopic rods 73, and their ends are fixedly connected to the material feeding block 75. After installation, the material feeding telescopic rod 73 is in an inclined state. The guide rod 74 has a segmented structure, including a connected thick rod and a thin rod.

[0054] Initially, the rotating sleeve 84 is fully retracted into the compactor housing 82 and located outside the working area of ​​the double-layer open mill 400 rollers. When extended, it is precisely positioned in the film working area below the lower roller group 2, and the slide block 803 is in its initial position at one end of the track 802. During operation, the telescopic drive motor 88 starts, driving the telescopic shaft 83 to extend, so that the rotating sleeve 84 reaches below the upper roller group 3 and contacts the left edge of the film. The slide table drive motor 807 starts, driving the slide block 803 to move to the right along the track 802, and the rotating sleeve 84 moves to the right simultaneously, pushing the film to the right along the rollers to gather and stack. When the slide block 803 moves to the preset position on the right end of the film, the telescopic shaft 83 retracts, and the rotating sleeve 84 disengages from the film and returns to the outside of the roller working area. The slide table drive motor 807 continues to drive the slide block 803 to move to the right to the outside of the right end of the film. At this time, the rotating sleeve 84 is in the external space on the right side of the film along with the slide block 803. The telescopic shaft 83 extends again, and the rotating sleeve 84 reaches below the roller and contacts the right edge of the film. The slide table drive motor 807 starts in reverse, the slide block 803 moves to the left, and the rotating sleeve 84 moves to the left simultaneously, pushing the film to the left to gather and stack. When the slide block 803 moves to the preset position on the left end of the film, the telescopic shaft 83 retracts, and the rotating sleeve 84 returns to the outside of the roller working area. The slide table drive motor 807 drives the slide block 803 to move to the left to the outside of the left end of the film, repeating the above process to realize the left and right reciprocating push and pull stacking of the film.

[0055] The bottom of the frame 1 is inclined, and the moving conveyor mechanism 4 is located at the bottom of the frame 1. Figure 9 As shown, the mobile conveying mechanism 4 includes a conveying device 42, which comprises two spaced-apart frames. Two conveying rollers are spaced apart between the two frames, and a conveyor belt is fitted around the outer side of each conveying roller. The roller shaft of one of the conveying rollers is connected to the output end of a conveying drive motor. Slider blocks 41 are fixed to the bottom of each of the two side frames of the conveying device 42. Guide rails 40 are respectively provided on both sides of the bottom of the frame 1. The sliders 41 are slidably connected to the corresponding guide rails 40. A drive telescopic rod 44 is fixed to the side wall of the frame. The output end of the drive telescopic rod 44 is hinged to a hinge seat 43 fixed to the bottom of the frame 1. An extension seat 46 extends from the rear of the frame 1, and a portion of the guide rail 40 is fixed to the top of the extension seat 46. A baffle plate 45 is fixed to the top of the frame.

[0056] It should be noted that the displacement telescopic rod 63, the flap telescopic rod 51, the scraper telescopic rod 131, the tug telescopic rod 73, and the drive telescopic rod 44 are all drive components capable of linear reciprocating motion, such as, but not limited to, electric cylinders, pneumatic cylinders, or hydraulic cylinders.

[0057] The working principle of this utility model is as follows: After the internal mixer 100 completes the initial mixing, the rubber compound is output through the tilting internal mixer outlet 101 to the hopper 201 of the elevator 200, and then conveyed by the elevator 200 to the lifting bucket 301 of the lifting device 300. The lifting device 300 then conveys the rubber compound to the feed hopper 12 of the double-layer open mill 400. After the rubber compound enters the feed hopper 12, the chuck mechanism 7 operates, and the chuck extension rod 73 drives the chuck block 75 to move towards the center of the feed hopper 12, pushing the rubber compound downward to prevent blockage and ensure continuous and stable feeding. The rubber compound sequentially enters the roller gap between the upper roller group 3 and the lower roller group 2, and completes the open milling under the shearing and squeezing action of the upper and lower rollers. During the rolling process, the upper baffle mechanism 6 and the lower baffle mechanism 5 respectively limit the rubber compound in the width direction to prevent the rubber compound from shifting or overflowing.

[0058] When the rubber compound needs to be repeatedly rolled to make the shearing and mixing of the rubber compound more uniform, the rubber compound is rolled by the lower roller group 2 and falls above the conveyor belt of the conveyor device 42. The conveyor device 42 conveys it forward. During the conveying process, the entire conveyor device 42 moves forward along the guide rail 40 under the driving action of the drive telescopic rod 44, so that the end of the conveyor belt is directly above the lifting bucket 301, so that the material finally falls accurately into the lifting bucket 301. The lifting device 300 then sends the material into the feeding hopper 12, repeating the above rolling and edge material recycling process to realize the automatic feeding and multiple rolling.

[0059] During the film conveying and circulation process, the scraping mechanism 13 works continuously. The scraper 134, driven by the scraper telescopic rod 131, closely adheres to the surfaces of the upper and lower rollers to remove residual adhesive adhering to the roller surface and ensure that the roller surface is clean. The scraped material falls into the lower roller group 2 and the conveyor belt of the conveying device 42 to participate in the rolling again.

[0060] At the same time, the tamping mechanism 8 drives the mounting arm 81 and the tamping machine housing 82 to move as a whole through the tamping linear slide table 80, and uses the telescopic drive motor 88 to drive the telescopic shaft 83 and the rotating sleeve 84 to reciprocate to push and pull the film output by the upper roller group 3 back and forth, replacing the traditional manual folding of the triangular bag operation, significantly reducing labor intensity and improving the level of automation and work efficiency.

[0061] Finally, after multiple automatic rolling and tamping processes by the automatic tamping mechanism 8, the rubber sheet is extruded by the sheeting machine 500, completing the automated operation of the entire rubber compounding production line.

[0062] As the film is fed to the film output machine 500, the cutting mechanism 17 located in front of the lower roller group 2 cuts off the edge material on both sides of the film, making the edges of the film neat. The cut edge material passes through the inner side of the guide rod 931 of the recycling guide assembly 93, and successively passes over the top of the first recycling roller 91 and the second recycling roller 92; the recycling drive motor 97 drives the first recycling roller 91 and the second recycling roller 92 to rotate through the cooperation of the recycling reducer 99, universal shaft 96, drive gear 95, driven gear 94 and chain, so as to guide the edge material back into the rolling gap of the lower roller group 2, realizing the automatic recycling and re-rolling of the edge material without manual intervention.

[0063] Through the above-described structure and workflow, this utility model achieves automatic rubber mixing, automatic scrap recycling, automatic multiple rolling, and automatic compaction of rubber materials, significantly reducing manual intervention, lowering equipment footprint and power consumption, and improving production efficiency and product quality stability.
