Description

Technical Field

[0001] This utility model relates to the technical field of sulfur fiber pressing equipment, and in particular to a pressing device for continuous production of sulfur fiber. Background Technology

[0002] Vulcanized fiber is a composite material made from high-purity pulp through gelation. It possesses properties such as high strength, wear resistance, and insulation, and is widely used in industrial products. In the continuous production process of vulcanized fiber, the roller press is one of the key pieces of equipment. Its core function is to press and dehydrate the pre-treated raw materials, laying the foundation for subsequent vulcanization reactions and finished product molding.

[0003] Traditional pressing devices used in the production of sulfurized fibers can remove excess moisture from raw materials by using the clamping pressure of two pressing rollers. However, during actual operation, impurities easily adhere to the outer surface of the pressing rollers. If these impurities are not cleaned in time, they will directly affect the pressing and dehydration effect of the pressing rollers on the material. Cleaning often requires manual operation with tools such as brushes, which is not only time-consuming and labor-intensive, but also requires stopping the machine for processing, thereby reducing the production efficiency of sulfurized fibers. Utility Model Content

[0004] This utility model relates to a pressing device for continuous production of sulfurized fibers. It solves the problem that although traditional pressing devices for sulfurized fiber production can remove excess water from raw materials by clamping two pressing rollers, in actual operation, the outer circumference of the pressing rollers is prone to sticking with debris. If not cleaned in time, it will affect the dehydration effect. Moreover, cleaning requires manual cleaning with tools, which is not only time-consuming and labor-intensive, but also requires stopping the machine for treatment, thus reducing the production efficiency of sulfurized fibers.

[0005] In a first aspect, this utility model provides a pressing device for continuous production of sulfurized fibers, specifically comprising: a water collection tank, a supporting top plate installed on the top of the water collection tank, and a pressing frame fixedly connected to the upper part of the supporting top plate; a control box installed on the front end face of the water collection tank; two pressing rollers rotatably connected in a left-right symmetrical arrangement inside the pressing frame, and a first pulley installed at the rear end of the rotating shaft of each of the two pressing rollers; two sets of cleaning components arranged in a left-right symmetrical arrangement inside the pressing frame; the cleaning components include a roller brush, the roller brush being rotatably connected inside the pressing frame, and a second pulley installed at the rear end of the rotating shaft of the roller brush, and the second pulley being connected to the first pulley via a belt; the bristles of the roller brush being in close contact with the outer peripheral surface of the pressing roller; and a conveying mechanism also being provided on the water collection tank.

[0006] Furthermore, a transmission reducer is installed on the front end face of the pressing frame, and the output shaft of the transmission reducer is fixedly connected to the front end of the shaft of one pressing roller on the right side. The input shaft of the transmission reducer is connected to the shaft of the drive motor, and the drive motor is installed on the left end face of the transmission reducer. A gear is installed on the outer rear end of the shafts of both pressing rollers, and the two gears mesh with each other.

[0007] Furthermore, a feed hopper is installed on the upper part of the pressing frame, and a discharge hopper is installed on the bottom of the pressing frame. The discharge port at the lower end of the feed hopper is located above and between the two pressing rollers.

[0008] Furthermore, the conveying mechanism includes a conveying roller and a conveying motor. The conveying roller is rotatably connected to the water collection tank, and a conveyor belt is externally connected to the conveying roller. A driven pulley is installed at the front end of the shaft of one of the left conveying rollers. The conveying motor is installed on the left end face of the water collection tank, and a driving pulley is installed on the shaft of the conveying motor. The driving pulley is connected to the driven pulley via a belt. The upper surface of the conveyor belt is inclined downward on the right side.

[0009] Furthermore, the cleaning assembly also includes a fixing plate, which is fixedly connected inside the water collection tank and located above the pressing roller. The bottom of the fixing plate is provided with a scraper that contacts the outer peripheral surface of the pressing roller.

[0010] Furthermore, the lower front side of the water collection tank is provided with a drain outlet that communicates with its interior, and a drain hose is connected to the front end of the drain outlet. A connecting plate is fixedly connected to the outside of the drain end of the drain hose, and a limiting post is fixedly connected to the bottom end face of the connecting plate. A positioning block is fixedly connected to the upper front face of the water collection tank, and a positioning hole is opened on the positioning block, and the positioning hole is inserted into the limiting post.

[0011] This utility model provides a pressing device for continuous production of sulfurized fibers, which has the following beneficial effects: This invention, through the design of its cleaning components, enables the left press roller to rotate clockwise via its left first and second pulleys and its left roller brush, while the right press roller rotates clockwise via its right first and second pulleys and its right roller brush. This removes debris adhering to the outer surfaces of both press rollers. Further scraping is then performed on the outer surfaces of the press rollers by the lower ends of two scrapers, creating a dual cleaning mechanism of rotational sweeping and rigid scraping. This achieves automatic cleaning of the outer surfaces of the two press rollers without the need for manual operation using brushes or other tools, saving time and labor, and eliminating the need for machine downtime, thereby improving the production efficiency of vulcanized fibers.

[0012] This utility model utilizes a combined design of a drain hose, connecting plate, limiting pin, and positioning block. By inserting the limiting pin into the positioning hole, the drain end of the drain hose is limited, and at this time, the drain end of the drain hose is higher than the water level inside the collection tank. This allows it to replace a valve for flow control. When draining, simply pull the limiting pin out of the positioning hole and place the drain end of the drain hose horizontally to perform the drainage operation. This effectively avoids the risk of blockage caused by debris in the water to the valve. Attached Figure Description

A second pulley 402 is installed at the rear end of the shaft of 01, and the second pulley 402 is connected to the first pulley 206 via a belt. The bristles of the roller brush 401 are in close contact with the outer circumferential surface of the press roller 201. A conveying mechanism 3 is also provided on the water collection tank 1. With the setting of the cleaning component 4, the two roller brushes 401 can rotate while the two press rollers 201 are rotating in opposite directions, and remove the debris adhering to the outer circumferential surface of the two press rollers 201, thereby realizing the automatic cleaning of the outer circumferential surface of the two press rollers 201. Moreover, there is no need for manual operation with brushes or other tools, which not only saves time and effort, but also eliminates the need to stop the machine for maintenance.

[0018] A transmission reducer 202 is installed on the front end face of the pressing frame 2, and the output shaft of the transmission reducer 202 is fixedly connected to the front end of the rotating shaft of a pressing roller 201 on the right side. The input shaft of the transmission reducer 202 is connected to the rotating shaft of the drive motor 203, and the drive motor 203 is installed on the left end face of the transmission reducer 202. A gear 207 is installed on the outer rear end of the rotating shafts of the two pressing rollers 201, and the two gears 207 mesh with each other, which enables the two pressing rollers 201 to rotate in opposite directions.

[0019] A feeding hopper 204 is installed on the upper part of the pressing frame 2, and a discharging hopper 205 is installed on the bottom of the pressing frame 2. The discharge port at the lower end of the feeding hopper 204 is located above the gap between the two pressing rollers 201, which is used to guide the raw materials to the gap between the two pressing rollers 201.

[0020] The conveying mechanism 3 includes a conveying roller 301 and a conveying motor 303. The conveying roller 301 is rotatably connected to the water collection tank 1, and a conveying belt 302 is externally connected to the conveying roller 301. A driven pulley is installed at the front end of the shaft of the left conveying roller 301. The conveying motor 303 is installed on the left end face of the water collection tank 1, and a driving pulley is installed on the shaft of the conveying motor 303. The driving pulley is connected to the driven pulley via a belt. The right side of the upper surface of the conveying belt 302 is inclined downwards. The conveying mechanism 3 is used to convey the pressed and dehydrated raw materials to the left.

[0021] The cleaning component 4 also includes a fixing plate 403, which is fixedly connected inside the water collection tank 1 and is located above the press roller 201. The bottom of the fixing plate 403 is provided with a scraper 404 that contacts the outer peripheral surface of the press roller 201. The lower ends of the two scrapers 404 further scrape the outer peripheral surface of the press roller 201, forming a dual cleaning mechanism of rotational sweeping and rigid scraping, which improves the cleaning effect on the outer peripheral surface of the press roller 201.

[0022] Example 2, based on Example 1, such as Figure 1 and Figure 6 As shown, a drain outlet 102 communicating with the interior is provided on the lower front side of the water collection tank 1, and a drain hose 103 is connected to the front end of the drain outlet 102. A connecting plate 104 is fixedly connected to the external drain end of the drain hose 103, and a limiting post 105 is fixedly connected to the bottom surface of the connecting plate 104. A positioning block 106 is fixedly connected to the upper front surface of the water collection tank 1, and a positioning hole 107 is provided on the positioning block 106. The positioning hole 107 is inserted into the limiting post 105. At this time, the drain end of the drain hose 103 is higher than the water level inside the water collection tank 1, so it can replace the valve to cut off the flow. When draining, it is only necessary to pull the limiting post 105 out of the positioning hole 107 and then place the drain end of the drain hose 103 horizontally to perform the drainage operation, which effectively avoids the risk of blockage of the valve caused by debris in the water.

[0023] The working principle of this embodiment is as follows: In use, the drive motor 203 is first started, which drives the right-side pressing roller 201 to rotate counterclockwise through the transmission reducer 202, and then drives the left-side pressing roller 201 to rotate clockwise through the transmission of two gears 207; then the conveyor motor 303 is started, which drives the driving pulley, the driven pulley, and the left-side conveyor roller 301 to rotate counterclockwise, thereby driving the conveyor belt 302 counterclockwise; then the raw materials for sulfurized fiber production are put into the feed hopper 204. Under the action of gravity, the raw materials fall through the discharge port at the lower end of the feed hopper 204 into the gap between the two pressing rollers 201. The two pressing rollers 201 rotating in opposite directions squeeze out the water from the raw materials. The squeezed-out water flows through the inclined surface of the upper part of the conveyor belt 302 under the action of gravity into the water collection tank 1 for collection. The dehydrated raw materials fall onto the upper surface of the conveyor belt 302, and the dehydrated raw materials are conveyed to the left by the counterclockwise driven conveyor belt 302.

[0024] During the opposite rotation of the two press rollers 201, the left press roller 201 rotates clockwise with the left first pulley 206 and the left second pulley 402, thereby removing the debris adhering to the outer circumference of the left press roller 201. Meanwhile, the right press roller 201 rotates clockwise with the right first pulley 206 and the right second pulley 402, thereby removing the debris adhering to the outer circumference of the right press roller 201. The lower ends of the two scrapers 404 further scrape the outer circumference of the press rollers 201, thus achieving automatic cleaning of the outer circumference of the two press rollers 201.

[0025] When it is necessary to drain the water collected inside the water collection tank 1, first move the connecting plate 104 upward, and pull the limiting pin 105 out of the positioning hole 107 on the positioning block 106, so that the drain end of the drain hose 103 loses its limiting function. Then, place the drain end of the drain hose 103 horizontally, and place a water collection container in front of the lower part of the drain end of the drain hose 103, so that the water collected inside the water collection tank 1 can be drained. By inserting the limiting pin 105 into the positioning hole 107, the drain end of the drain hose 103 is limited, and at this time the drain end of the drain hose 103 is higher than the water level inside the water collection tank 1, so that it can replace the valve to cut off the flow and avoid the risk of blockage caused by impurities in the water.
