Description

Technical Field

[0001] This utility model relates to the field of rubber sheet processing technology, and in particular to a water-cooled rubber sheet surface dehydration mechanism. Background Technology

[0002] Rubber sheets are usually made from rubber raw materials through plasticizing or mixing. The temperature of the rubber raw materials after plasticizing or mixing is very high, so the rubber sheets need to be cooled. The existing cooling method for rubber sheets is usually to cool them with cooling water. After the rubber sheets are cooled, the cooling water on the surface of the rubber sheets needs to be wiped off.

[0003] Existing dehydration methods typically involve passing a rubber sheet between two sets of wiping rollers to remove water. However, the distance between the two sets of wiping rollers is usually fixed, making it impossible for them to adapt to different thicknesses. This can lead to problems such as the wiping rollers squeezing the rubber sheet or incomplete dehydration. If the surface moisture is not completely removed, it will affect the quality of subsequent processing. For example, if the surface moisture is not completely removed, the risk of bulging in the product increases during the subsequent vulcanization process.

[0004] Therefore, there is an urgent need for a water-cooled rubber sheet surface dewatering mechanism to improve the quality of dewatering rubber sheet surfaces of different thicknesses.

[0005] A gas spring is an industrial component that provides support, cushioning, braking, height adjustment, and angle adjustment. It consists of the following parts: a pressure cylinder, piston rod, piston, sealing guide sleeve, filling material (inert gas or an oil-gas mixture), internal and external control elements (referring to a controllable gas spring), and connectors. The principle is to fill the sealed pressure cylinder with inert gas or an oil-gas mixture, making the pressure inside the chamber several times or tens of times higher than atmospheric pressure. The piston rod's movement is achieved by utilizing the pressure difference created by the smaller cross-sectional area of ​​the piston rod compared to the piston's cross-sectional area.

[0006] The hot air knife combines the functions of a heater and a high-speed air knife. It directly uses electric heat for drying, highlighting the advantages of both a hot air blower and a high-speed air knife, greatly improving the drying effect. When using it, a dedicated temperature control box and a fan (air compressor, vortex fan or centrifugal fan) must be used separately. Utility Model Content

[0007] To address the aforementioned technical problems, this utility model provides a water-cooled rubber sheet surface dewatering mechanism, which solves the problem that existing rubber sheet surface dewatering equipment has poor applicability and cannot completely remove water from the surface of rubber sheets of different thicknesses.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0009] A water-cooled rubber sheet surface dehydration mechanism includes a frame, on which a first dehydration unit and a second dehydration unit are provided. The first dehydration unit includes two first hot air knives and a first conveying roller. The blowing direction of the two first hot air knives is opposite to the direction in which the rubber sheet travels on the frame. One of the two first hot air knives is mounted on the frame, and the other has swing arms at both ends. A bracket is hinged to the end of the swing arm away from the first hot air knives. The bracket is fixed to the frame. A first gas spring is connected to the end of the swing arm near the bracket. The first gas spring is hinged to the frame. The distance between the two first hot air knives is changed by the swing arm through the first gas spring.

[0010] Furthermore, the second dewatering unit includes a dewatering tank disposed above the first dewatering unit. At least one second hot air knife and a third hot air knife are respectively provided on two opposing side walls inside the dewatering tank. The blowing direction of the second hot air knife and the third hot air knife is opposite to the direction in which the rubber sheet travels on the frame.

[0011] Furthermore, the two ends of the second hot air knife are hinged with connecting parts, and the other end of the connecting parts is hinged to the side wall of the dewatering tank. The inner wall of the dewatering tank is provided with second air springs at both ends of the second hot air knife. The output end of the second air spring is hinged to both ends of the second hot air knife. The second hot air knife changes the distance with the third hot air knife under the combined action of the second air spring and the connecting parts.

[0012] Furthermore, the swing arm has multiple first adjustment holes along its length for adjusting the position of the first conveying roller.

[0013] Furthermore, the swing arm has multiple second adjustment holes that are hinged to the bracket along its length, and the bracket has multiple hinge holes along its height, the hinge holes being of the same diameter as the second adjustment holes.

[0014] Furthermore, at least one second conveying roller is rotatably provided inside the water removal tank, and the water removal tank is provided with sliding holes at both ends of the second conveying roller, and a third adjusting hole is provided on both sides of the sliding hole.

[0015] Furthermore, the frame is provided with a first transition roller located between the first dewatering unit and the second dewatering unit.

[0016] Furthermore, the frame is equipped with a second transition roller at the feed inlet of the second dewatering unit.

[0017] Furthermore, there are two of each of the second and third hot air knives, and they are arranged symmetrically in pairs.

[0018] Furthermore, locking components are provided at the joints between the two ends of the first hot air knife and the swing arm, and the blowing angle of the first hot air knife is changed by the locking components.

[0019] In summary, the beneficial technical effects of this utility model are as follows:

[0020] (1) The first air spring controls the extension and retraction of the output end and acts on the swing arm. The swing arm further raises and lowers the height of the first hot air knife at one end under the cooperation of the bracket, thereby changing the distance between the two first hot air knives to accommodate the dewatering of rubber sheets of different thicknesses. During the dewatering process, the elasticity of the first air spring can make one of the first hot air knives stick tightly to the surface of the rubber sheet, thus improving the quality and efficiency of dewatering.

[0021] (2) By using the elastic control of the second air spring to control the second hot air knife, the rubber sheet can be dehydrated twice, which further improves the dehydration quality. Attached Figure Description

Detailed Implementation

[0029] The present invention will now be described clearly and completely with reference to the embodiments.

[0030] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0031] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] See appendix Figure 1-6 The diagram shows a water-cooled rubber sheet surface dehydration mechanism, including a frame 1. One end of the frame 1 is equipped with a cooling unit for cooling the rubber sheet 25, and the other end is equipped with a traction unit for pulling the rubber sheet 25 forward. A first dehydration unit and a second dehydration unit are located between the cooling unit and the traction unit. The first dehydration unit includes two vertically arranged first hot air knives 2. The blowing direction of the two first hot air knives 2 is opposite to the direction in which the rubber sheet 25 travels on the frame 1. One hot air knife is mounted on the frame 1, and the two ends of the other first hot air knife 2 are bolted to a swing arm 4 via locking components 5. The blowing direction of the first hot air knife 2 can be changed by the locking components 5. The swing arm 4 has multiple first adjustment holes 7 along its length. The first conveying roller 3 is installed on the swing arm 4 through the first adjustment holes 7. At this time, the distance between the first conveying roller 3 and the first hot air knife 2 can be adjusted through the first adjustment holes 7. At the same time, multiple second adjustment holes 8 are provided along the length of the swing arm 4 at the end away from the first hot air knife 2. A bracket 6 is fixedly provided on the frame 1 near the second adjustment holes 8. Multiple hinge holes 9 are provided on the bracket 6 along the height direction. The bracket 6 and the swing arm 4 are connected through the cooperation of the second adjustment holes 8 and the hinge holes 9. Therefore, the position of the first hot air knife 2 on the frame 1 can be changed through the second adjustment holes 8.

[0033] A first air spring 10 is hinged to one end of the swing arm 4 near the bracket 6. The first air spring 10 is hinged to the frame 1. The first air spring 10 acts on one end of the swing arm 4 through its output end. The swing arm 4 further uses the lever principle with the bracket 6 to raise and lower the first hot air knife 2 at the other end, thereby changing the distance between the two first hot air knives 2. This allows for the removal of water from the surface of rubber sheets 25 of different thicknesses. At the same time, through the elastic action of the first air spring 10 on the swing arm 4, the first hot air knife 2 can be in real time attached to the surface of the rubber sheet 25, improving the water removal quality.

[0034] Furthermore, a support frame 11 is provided on the frame 1, and the second dewatering unit is fixed on the support frame 11. The second dewatering unit includes a dewatering tank 12. Two second hot air knives 13 and a third hot air knife 14 are respectively provided on the two opposing side walls inside the dewatering tank 12. The second hot air knives 13 and the third hot air knives 14 are symmetrical in pairs and their air blowing direction is opposite to the traveling direction of the rubber sheet 25. The two ends of the second hot air knife 13 are hinged to the connecting parts 16, and the other end of the connecting parts 16 is connected by a hinge. The connector is attached to the side wall of the dewatering tank 12. At the same time, the side wall of the dewatering tank 12 is hinged to the two ends of the second hot air knife 13. The output end of the second hot air knife 17 is hinged to the two ends of the second hot air knife 13. The third hot air knife 14 is fixed relative to the second hot air knife 13 by the fixing column 15 set on the support frame 11. The second hot air knife 13 changes the distance between itself and the third hot air knife 14 by using the second air spring 17 to achieve secondary dewatering of the surface of the rubber sheet 25.

[0035] Furthermore, two second conveying rollers 18 are rotatably mounted inside the water tank 12 via bearings, and the water tank 12 has sliding holes 21 at both ends of the second conveying rollers 18 for lateral sliding. The water tank 12 also has multiple third adjusting holes 22 on both sides of the sliding holes 21 for fixing the bearings. In use, the second conveying rollers 18 are moved laterally by the cooperation of the third adjusting holes 22 and the sliding holes 21, thereby changing the tension of the second conveying rollers 18 on the rubber sheet 25.

[0036] Furthermore, a first transition roller 19 is provided between the first dewatering unit and the second dewatering unit on the frame 1, and a second transition roller 20 is provided at the feed inlet of the second dewatering unit on the frame 1.

[0037] Further details can be found in the appendix. Figure 4 As shown, the first hot air knife 2, the second hot air knife 13, and the third hot air knife 14 have the same structure. Each has a housing, with an air inlet pipe 23 at one end and an air outlet 24 along the length of the front end of the housing. In use, air is drawn in and compressed by a turbine fan, and then the compressed air is passed into a temperature controller for heating. The heated hot air is connected to the air inlet pipe 23 through a pipe and then blown out from the air outlet 24. The water stains adhering to the surface of the rubber sheet 25 are removed by the flow rate and heat of the hot air.

[0038] During operation, based on the thickness of the rubber sheet 25, the distance between the two first hot air knives 2 and the distance between the second hot air knife 13 and the third hot air knife 14 are changed by the first air spring 10 and the second air spring 17, respectively. Then, the rubber sheet 25 coming out of the cooling unit is placed between the upper and lower first hot air knives 2, and then passes through the first transition roller 19 and the second conveyor wheel in sequence between the second hot air knife 13 and the third hot air knife 14. Finally, it passes through the second transition roller 20. Then, hot air is introduced into the first hot air knife 2, the second hot air knife 13 and the third hot air knife 14, respectively. Then, the rubber sheet 25 moves forward under the action of the traction unit. During the movement, the hot air blown out at high speed removes water from the surface of the rubber sheet 25.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape and principle of the present utility model should be included within the scope of protection of the present utility model.
