Description

Technical Field

[0001] The utility model relates to the technical field of flat plate vulcanizing machines, in particular to a flat plate vulcanizing machine with all-round safety protection. Background Art

[0002] The flat plate vulcanizer is mainly used for vulcanizing flat belts (such as conveyor belts, transmission belts, referred to as flat belts). It has the advantages of high pressure per unit area of the hot plate, reliable equipment operation and low maintenance. The main function of the flat plate vulcanizer is to provide the pressure and temperature required for vulcanization. The pressure is generated by the hydraulic system through the hydraulic cylinder, and the temperature is provided by the heating medium (usually steam).

[0003] The existing flat plate vulcanizer generates a large amount of hot steam when heated, and the hot steam has no fixed source and drifts around the flat plate vulcanizer. Especially when used in a laboratory, if the waste gas generated by vulcanization, such as hydrogen sulfide, is not discharged in time, the waste gas will spread throughout the laboratory, which not only affects the laboratory environment, but also causes harm to the experimenters.

[0004] Existing vulcanizers are usually open when in use, such as the utility model patent with publication number CN 217752326 U and publication number 2022.11.08, which discloses a flat vulcanizer with a safety protection structure, including a flat vulcanizer body, both sides of the flat vulcanizer body are fixedly connected with pillars, one side of the top of the pillar is fixedly connected with a top plate, one side of the top of the top plate is fixedly connected with a support rod, the top of the support rod is fixedly connected with a cross plate, and a first door curtain is provided on the side of the bottom end of the cross plate close to the flat vulcanizer body;

[0005] The utility model gathers the hot steam generated when the flat plate vulcanizer body is working by arranging the first door curtain and the second door curtain to prevent the hot steam from overflowing and causing scalding to the staff. Then, by arranging the filter box, not only the hot steam can be discharged uniformly, but also the harmful gas generated when the flat plate vulcanizer body is working can be filtered and purified to prevent the health of the staff from being hindered. At the same time, the environment can be protected, and the use is safer and more environmentally friendly.

[0006] Although the utility model gathers and collects the exhaust gas through the first door curtain and the second door curtain and discharges the exhaust gas uniformly through the filter box, since the first door curtain and the second door curtain are not completely sealed, more or less exhaust gas will still flow to the outside during or after vulcanization. This solution is acceptable if used in a normal workshop factory, but if a vulcanization experiment is carried out in a laboratory, due to the limited space in the laboratory, if this part of the exhaust gas is dispersed into the laboratory, it will be very detrimental to the entire environment of the laboratory and the health of the staff.

[0007] Therefore, there is an urgent need for a flat vulcanizing machine with all-round safety protection to prevent waste gas from flowing into the laboratory during vulcanization experiments in the laboratory, ensure the internal environment of the laboratory, and reduce the harm of waste gas to experimental personnel. Content of the Utility Model

[0008] In view of the above technical problems, the present utility model provides a flat vulcanizing machine with all-round safety protection, which is used to solve the problem that during vulcanization experiments in existing laboratories, the waste gas generated is not fully discharged, and there is still waste gas flowing into the laboratory, causing adverse effects on the laboratory environment and experimental personnel.

[0009] The above technical objectives of the present utility model are achieved through the following technical solutions:

[0010] A flat vulcanizing machine with all-round safety protection, including a base and a flat vulcanizing machine arranged on the base, characterized in that: a flow prevention cover is provided on the base, the flat vulcanizing machine is located inside the flow prevention cover, and an exhaust pipe is provided at the top of the flow prevention cover;

[0011] Blowing boxes are respectively arranged on the front and rear sides of the flat vulcanizing machine. A number of blowing holes are linearly opened at the top of the blowing box. Air inlet interfaces are provided at both ends of the blowing box. An air inlet main pipe is connected to the air inlet interfaces through pipelines, and a blower is connected to the air inlet main pipe;

[0012] A protective door is provided on one side of the flow prevention cover where the blowing box is located, and a transparent viewing window is provided on the protective door.

[0013] Further, the blowing holes are sequentially dispersed towards both ends with the length center of the blowing box as the dividing line, and the radius of the blowing holes decreases sequentially.

[0014] Further, the radius of the blowing holes is set according to the formula: an = a1 + (n - 1)d;

[0015] Where a1 is the radius of the first hole at the end of the blowing box;

[0016] an is the general term formula of the radius of the nth hole, and d is the radius tolerance.

[0017] Further, a connecting plate is arranged along the length direction on the side of the blowing box close to the blowing holes, and a deflector is detachably installed on the connecting plate.

[0018] Further, a clamping seat is provided at the bottom of the blowing box, and a clamping groove is provided in cooperation with the clamping seat, and the clamping groove is fixed on the base.

[0019] Further, slideways are symmetrically arranged on both sides of the protective door. A travel hole is formed in the slideway along the length direction. An installation plate is provided on one side of the anti-diffusion cover close to the slideway. A driving cylinder is arranged on the installation plate. The output end of the driving cylinder is connected to the protective door and controls the up and down sliding of the protective door along the slideway.

[0020] To sum up, the beneficial technical effects of the present utility model are as follows:

[0021] (1) By using the air blowing boxes arranged on the front and rear sides of the flat vulcanizing machine to continuously blow the external air from the hair dryer upward through the air blowing holes, the flow rate of the waste gas flowing towards the exhaust pipe is increased. At the same time, using the external wind force as an auxiliary force makes the flow direction of the waste gas more concentrated, preventing it from diffusing randomly everywhere, reducing the content of the waste gas diffusing into the laboratory. At the same time, the wind blown out by the air blowing boxes forms two invisible wind walls on both sides of the flat vulcanizing machine. The waste gas can only flow upward between the two wind walls. At the same time, the entire flat vulcanizing machine is sealed by the anti-diffusion cover, further reducing the diffusion of the waste gas into the laboratory. Only vulcanization operations are carried out through the protective door, reducing the communication area between the flat vulcanizing machine and the laboratory, and further ensuring the environment inside the laboratory and the health of the experimental personnel.

[0022] (2) By using the air blowing holes with gradually increasing radii, it is ensured that the air volume blown out at any position of the entire air blowing box is the same, thereby reducing the difference in the air volume blown out by each air blowing hole, and avoiding the disorder and random diffusion of the waste gas under the air volume difference. Since the wind from the hair dryer flows from both ends of the air blowing box to the middle, the radii of the air blowing holes at both ends are smaller than those of the air blowing holes in the middle, and the air volume is compensated by the gradually increasing radii.

[0023] (3) By using the guide plate, the directionality of the wind blown out by the air blowing box can be improved, ensuring that the wind always blows towards the exhaust pipe.

[0024] (4) By using the driving cylinder to control the up and down movement of the protective door, manual operation by manpower is replaced, thereby ensuring the quality of the closing of the protective door and improving the sealing performance of the anti-diffusion cover.

Detailed implementation manners

[0032] The present utility model will be clearly and completely described below in conjunction with embodiments.

[0033] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If this specific posture changes, the directional indications will also change accordingly.

[0034] In the description of the embodiments, the terms "arranged", "connected", etc. should be understood in a broad sense unless otherwise clearly specified and limited. 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 directly connected or connected through an intermediate medium, and it can also be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0035] See the attached Figures 1-6, A flat vulcanizer with all-round safety protection is shown, including a base 1. The base 1 is bolted with a spill prevention cover 2. Inside the spill prevention cover 2, there is a flat vulcanizer 3 for vulcanization experiments. The flat vulcanizer 3 is equipped with a hydraulic cylinder 20 that provides vulcanization pressure and a vulcanization plate 19 for vulcanization. At the top of the spill prevention cover 2, there is an exhaust pipe 4, and the exhaust pipe 4 is connected to the main exhaust pipe 4 of the laboratory. During use, the waste gas in the spill prevention cover 2 is discharged to the outside by negative pressure through the exhaust pipe 4. On the front and back sides of the flat vulcanizer 3 where the base 1 is located, that is, on the sides for feeding and taking materials, there is a blowing box 10 respectively. The blowing box 10 is made of 304 stainless steel. A number of blow holes 11 are linearly arranged at the top of the blowing box 10. At the same time, air inlet interfaces 9 are respectively provided at both ends of the blowing box 10. An air inlet main pipe 8 is connected to the air inlet interfaces 9, and an industrial-grade hair dryer 7 is connected to the air inlet main pipe 8. During use, the hair dryer 7 sends outside air into the blowing box 10 through the air inlet main pipe 8 from the air inlet interfaces 9, and the blow holes 11 blow the outside air from both ends of the air inlet interfaces 9 towards the direction of the exhaust pipe 4. Through blowing, the waste gas generated during the vulcanization experiment can be more concentrated and quickly discharged from the exhaust pipe 4. Through blowing, the directionality of the waste gas is improved, avoiding the random dispersion into the laboratory, thus ensuring the environment inside the laboratory and the health of the experimental personnel. At the same time, a protective door 5 is provided on one side of the spill prevention cover 2 near any one of the blowing boxes 10. Through the upward blowing of the blowing box 10, it further avoids the dispersion of waste gas into the laboratory when the protective door 5 is opened;

[0036] As a flat vulcanizer 3 with all-round safety protection, in order to ensure that the air volume of each blow hole 11 on the blowing box 10 is consistent and prevent the disorder of air flow caused by inconsistent air volumes, resulting in the random dispersion of waste gas, it is arranged in a way that takes the length center of the blowing box 10 as the dividing line and the radius decreases successively towards both ends. Since the air from the hair dryer 7 flows from both ends of the blowing box towards the middle, the radius closer to the blow hole 11 is larger as it gets closer to the length center of the blowing box 10. In this way, the air volume can be compensated by the successively increasing radius. At the same time, the radius of the blow hole 11 is set according to the formula: an = a1+(n - 1)d; where a1 is the radius of the first hole at the end of the blowing box 10; an is the general term formula for the radius of the nth hole, and d is the radius tolerance. Specifically, if a1 = 0.2mm and d = 0.1mm, then the radius of the third hole a3 = 0.2+(3 - 1)×0.1 = 0.4mm, and so on;

[0037] As a flat vulcanizing machine 3 with all-round safety protection, in order to improve the directionality of the air flow, a connecting plate is provided at one end of the air blowing box 10 where the air blowing holes 11 are located. A flow guiding plate 12 is installed on the connecting plate through bolts. Through the flow guiding plate 12, the air blown out from the air blowing box 10 becomes more concentrated and powerful, with better directionality, and can better block the waste gas coming out from the vulcanizing plate 19, especially when the protective door 5 is opened.

[0038] As a flat vulcanizing machine 3 with all-round safety protection, a transparent window 6 is provided on the protective door 5. During vulcanization, the vulcanization working conditions can be clearly observed through the transparent window 6. At the same time, slide ways 15 are symmetrically provided on both sides of the protective door 5 where the anti-scattering cover 2 is located. A travel hole 16 is opened along the length direction on the slide way 15. The protective door 5 is fixedly provided with a connecting column 18 through the travel hole 16. At the same time, a mounting plate is provided on one side of the protective door 5, and a driving cylinder 17 is provided on the mounting plate. The driving cylinder 17 is specifically a rodless cylinder. When the protective door 5 is opened and closed, the output end of the driving cylinder 17 is connected to the connecting column 18 on the protective door 5, and the driving cylinder 17 drives the protective door 5 to slide up and down along the slide way 15.

[0039] During use, the driving cylinder 17 drives the protective door 5 to open upwards. Then, the rubber to be vulcanized is placed on the vulcanizing plate 19. Then, the driving cylinder 17 is used again to close the protective door 5. Then, the hydraulic cylinder is used to apply pressure to the vulcanizing plate 19 to start vulcanization. During vulcanization, the air blowers 7 on both sides of the anti-scattering cover 2 are started, and the outside air is continuously blown out from the air blowing holes 11 of the air blowing box 10 through the intake main pipe 8. At this time, the air will flow upwards rapidly under the action of the flow guiding plate 12 and then discharge the waste gas generated during vulcanization to the exhaust pipe 4, thereby greatly reducing the probability of the waste gas flowing into the laboratory interior, especially when the protective door 5 is opened, and effectively ensuring the environment inside the laboratory and the health of the experimental personnel.

[0040] It should be noted that in order to ensure the constancy of the temperature of the flat vulcanizing machine during vulcanization, during the implementation of the present utility model, it is mainly aimed at exhausting air outwards when vulcanization ends.

[0041] The above is only the preferred specific implementation manner of the present utility model, and does not limit the protection scope of the present utility model accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present utility model should be covered within the protection scope of the present utility model.
