Description

Technical Field

[0001] This utility model belongs to the field of steam heating technology, specifically a steam engine for easy retrieval of objects. Background Technology

[0002] Steam heating equipment is a type of heat exchange device that uses the thermal energy contained in steam to indirectly heat air, water, or solid materials. Its core function is to raise the temperature of the target medium through heat transfer. Because it has the function of heating the entire process, it is suitable for dyeing and finishing laboratories to conduct experiments on drying, setting, steaming, resin processing baking, pad dyeing baking, and thermosetting, so as to obtain the correct resin processing formula, test the color change of dyeing and finishing processes, and verify the results of chemical tests.

[0003] In existing technology, after a steam engine has finished heating the material, it often needs to release pressure for a period of time to discharge the steam inside the machine before the pull plate can be opened to take out the material, in order to prevent workers from being burned. However, because existing steam engines lack a locking mechanism for the pull plate, workers can easily open the pull plate after heating. This makes it very easy for workers to accidentally touch the pull plate during daily use, resulting in the escaped steam burning workers after the pull plate is opened.

[0004] Therefore, this utility model provides a steam engine for easy retrieval of objects. Utility Model Content

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] like Figures 1 to 10As shown, the present invention provides a steam engine for easy retrieval of items, comprising a body 1, a placement cavity within the body 1, a pull-out plate 2 attached to the outer side of the placement cavity, a placement frame 4 fixedly connected to the pull-out plate 2, a filter plate 7 mounted on the placement frame 4, handles 8 fixedly connected to both sides of the top of the filter plate 7, guide blocks 8 fixedly connected to both inner walls of the placement cavity, guide plates 5 slidably connected to both guide blocks 11, and both guide plates 5 fixedly connected to the pull-out plate 2. The pull-out plate 2 is located above the filter plate 7, and the top two sides of the placement cavity... Each side is fixedly connected to a mounting bracket 12, which is equipped with a one-way locking component. The one-way locking component can lock the guide plate 5 that slides into the placement cavity. The machine body 1 is provided with two sealing cavities 16, which are located on both sides of the placement cavity. The sealing cavity 16 is equipped with an unlocking component, which can release the one-way locking component from locking the guide plate 5. During operation, the operator places the material to be steam heated on the filter plate 7, then places the filter plate 7 on the placement frame 4, and slides the pull plate 2 inward to allow the placement frame 4 to slide. The guide plate 5 slides into the placement cavity of the machine body 1. The guide plate 5 is locked in place by a one-way locking assembly, thus locking the pull-out plate 2. This prevents the placement frame 4 from sliding out accidentally after heating, causing steam that hasn't yet escaped from the placement cavity to escape through the pull-out plate 2 and potentially injure the worker. After the steam in the placement cavity is released, the one-way locking assembly is released by the unlocking assembly, allowing the worker to slide the pull-out plate 2 to remove the placement frame 4 from the placement cavity, thus facilitating the worker's work. The operator removed the aluminum plate along with the material, solving the problem in the existing technology where, after the steam engine finishes heating the material, it often needs to depressurize for a period of time to release the steam inside the machine body 1 before the pull-out plate 2 can be opened to remove the material, thus preventing workers from being burned. However, because the existing steam engine lacks a locking mechanism for the pull-out plate 2, workers can easily open the pull-out plate 2 after heating. This makes it very easy for workers to accidentally touch the pull-out plate 2 during daily use, resulting in the escaped steam burning workers after the pull-out plate 2 is opened.

[0031] The one-way locking assembly includes a rotating shaft 13, a pawl 14, and a torsion spring 15. The rotating shaft 13 is rotatably connected to the mounting bracket 12. The pawl 14 is fixedly connected to the rotating shaft 13. The torsion spring 15 is fixedly connected between the pawl 14 and the mounting bracket 12. The torsion spring 15 is sleeved on the rotating shaft 13. Toothed blocks 6 are evenly fixed to the top of the guide plate 5. The pawl 14 is adapted to the toothed blocks 6. A rubber pad 3 is fixedly connected to the side of the pull-out plate 2 near the body 1. During operation, when the pull-out plate 2 slides inward and drives the guide plate 5, the toothed blocks 6 on the guide plate 5 continuously pass through the pawl 14 until the rubber pad 3 on the pull-out plate 2 is in contact with the outer wall of the body 1. The toothed blocks 6 on the guide plate 5 can be locked by the torsion spring 15 in conjunction with the pawl 14, thereby locking the pull-out plate 2.

[0032] The unlocking assembly includes a spur gear 17, a rack plate 18, a fixed sleeve 19, and a limiting rod 23. One end of the rotating shaft 13 extends into the sealing cavity 16 and is fixedly connected to the spur gear 17. The top of the spur gear 17 is meshed with the rack plate 18. A limiting rod 23 is fixedly connected to one side of the rack plate 18. The fixed sleeve 19 is embedded in the body 1 on one side of the sealing cavity 16. The end of the limiting rod 23 away from the rack plate 18 extends through the fixed sleeve 19 to the outside of the body 1 and is fixedly connected to a wheel 26. During operation, when it is necessary to open the pull-out plate 2, the wheel 26 is slid outward, causing the limiting rod 23 to move along... The fixed sleeve 19 slides, which drives the rack plate 18 to slide, causing the spur gear 17 to rotate. This, in turn, causes the rotating shaft 13 to drive the pawl 14 to rotate. The pawl 14 moves away from the toothed block 6, making it easier for the operator to directly open the pull plate 2 and take out the material. As the pawl 14 moves away from the toothed block 6, it pushes against the toothed block 6, causing the guide plate 5 to slide inward. This causes the pull plate 2 to press against the rubber pad 3. The rubber pad 3 not only enhances the sealing effect between the pull plate 2 and the machine body 1, but also ensures the elastic gap between the pull plate 2 and the outer wall of the machine body 1 when the pawl 14 moves away from the toothed block 6.

[0033] The inner wall of the fixed sleeve 19 is symmetrically provided with a limiting groove 20, an arc-shaped groove 21, and a recess 22. The limiting groove 20 communicates with the arc-shaped groove 21, and the arc-shaped groove 21 communicates with the recess 22. A limiting block 24 is fixedly connected to the limiting rod 23. The limiting block 24 is symmetrically provided with protrusions. The protrusions on the limiting block 24 are slidably connected to both the limiting groove 20 and the arc-shaped groove 21. The protrusions on the limiting block 24 are adapted to the recess 22. A spring 25 is fixedly connected between the limiting block 24 and the inner wall of the fixed sleeve 19. During operation, when the guide plate 5 slides into the placement cavity along with the pull plate 2, the toothed block 6 drives the pawl 14 to rotate intermittently, causing the spur gear 17 on the rotating shaft 13 to drive the rack plate 18 to slide back and forth. This causes the limiting rod 23 to drive the limiting block 24 to slide back and forth along the limiting groove 20 until the rubber pad 3 is in contact with the outer wall of the machine body 1. The spring 25 then... The locking effect of the pawl 14 on the guide plate 5 can be further enhanced. When the operator slides the wheel 26 outward, the limit rod 23 drives the limit block 24 to slide from the limit groove 20 to the arc groove 21. The spring 25 is stretched. During this process, the rack plate 18 drives the spur gear 17 to rotate, so that the rotating shaft 13 drives the pawl 14 to rotate away from the tooth block 6 on the guide plate 5. Then, the operator rotates the wheel 26 to drive the limit block 24 on the limit rod 23 to rotate, so that the protrusion on the limit block 24 rotates and slides along the arc groove 21 until it corresponds to the groove 22. The wheel 26 is released, and the protrusion on the limit block 24 slides into the groove 22 through the pulling force of the spring 25 and completes the locking. At the same time, the pawl 14 rotates but does not contact the tooth block 6, freeing the operator's hands and avoiding the situation where the operator needs to hold the wheel 26 all the time when opening the pull-out plate 2.

[0034] The rotating shaft 13 is a hollow rod. A through groove 27 is symmetrically opened at one end of the rotating shaft 13 near the spur gear 17. A through groove 28 is symmetrically opened at one end of the limiting rod 23 near the rack plate 18. The through groove 28 communicates with the inner cavity of the limiting rod 23. A circular groove is provided on the side of the wheel 26 away from the machine body 1. Air passages 29 are evenly opened in the wheel 26. The air passages 29 communicate with the inner cavity of the limiting rod 23 and the circular groove. A nozzle 30 is fixedly installed on the inner wall of the air passage 29 near the circular groove. The air outlet end of the nozzle 30 is conical.

[0035] The inner wall of the circular groove of the wheel 26 is provided with threads, and a sealing cap 33 is threadedly connected to the circular groove of the wheel 26.

[0036] A support shaft 31 is rotatably connected to the circular groove of the wheel 26. Multiple sets of fan blades 32 are fixed to the support shaft 31. The nozzle 30 is adapted to the fan blades 32. During operation, after heating is completed and the machine body 1 is stopped, the operator rotates the sealing cover 33 outward, so that the steam in the machine body 1 enters the rotating shaft 13 and is discharged from the first channel 27. Then it enters the limiting rod 23 through the second channel 28, and enters the air passage 29 along the inner cavity of the limiting rod 23. Finally, it is sprayed out through the nozzle 30 on the air passage 29, so that the fan blades 32 and the support shaft 31 rotate accordingly until the steam in the machine body 1 is completely discharged. The operator can judge the discharge of hot steam in the machine body 1 by observing the rotating fan blades 32, so as to avoid the situation of being burned when opening the pull-out plate 2 if the steam is not completely discharged. In addition, since the outlet end of the nozzle 30 is conical, the steam will produce a sharp sound when it is discharged from the nozzle 30, which makes it easier for the operator to further judge the discharge of steam.

[0037] The top two sides of the placement frame 4 are evenly provided with positioning grooves 9, which are hemispherical in shape. The bottom two sides of the filter plate 7 are evenly fixed with positioning blocks 10, which are adapted to the positioning grooves 9. During operation, the positioning grooves 9 on the placement frame 4 and the positioning blocks 10 on the bottom of the filter plate 7 cooperate to facilitate the operator to place the filter plate 7 on the placement frame 4 and prevent the filter plate 7 from shaking on the placement frame 4.

[0038] Working principle: During operation, the operator places the material requiring steam heating on the filter plate 7, then places the filter plate 7 on the placement frame 4. By sliding the pull plate 2 inward, the placement frame 4 slides into the placement cavity of the machine body 1. Simultaneously, the guide plate 5 slides into the placement cavity. The toothed blocks 6 on the guide plate 5 continuously pass through the pawl 14 until the rubber pad 3 on the pull plate 2 is in contact with the outer wall of the machine body 1. Through the torsion spring 15 and the pawl 14, the toothed blocks 6 on the guide plate 5 can be locked in place, thereby locking the pull plate 2. When the operator slides the wheel 26 outward, the limiting rod 23 drives the limiting block 24 to slide from the limiting groove 20 to the arc groove 21, stretching the spring 25. During this process, the rack plate 18 drives the spur gear 17 to rotate, causing the rotating shaft 13 to drive the pawl 14 to rotate away from the toothed block 6 on the guide plate 5. Then, the operator rotates the wheel 26, causing the limiting block 24 on the limiting rod 23 to rotate, causing the protrusion on the limiting block 24 to rotate and slide along the arc groove 21 until it corresponds to the groove 22. The operator then releases the wheel 26, allowing the spring to release the pressure. The pulling force of 25 causes the protrusion on the limiting block 24 to slide into the groove 22 and complete the locking. At the same time, the pawl 14 rotates but does not contact the toothed block 6, freeing the operator's hands and avoiding the need for the operator to hold the wheel 26 while opening the pull-out plate 2. After heating is completed and the machine body 1 stops, the operator rotates the sealing cover 33 outward, allowing the steam in the machine body 1 to enter the rotating shaft 13 and then exit from the first through groove 27, and then enter the limiting rod 23 through the second through groove 28, and then along the limiting rod 23. The steam then enters the air passage 29 from the inner cavity, and finally exits through the nozzle 30 on the air passage 29, causing the fan blade 32 and the support shaft 31 to rotate until the steam inside the machine body 1 is completely discharged. The operator can judge the discharge of hot steam inside the machine body 1 by observing the rotating fan blade 32, so as to avoid being burned when opening the pull-out plate 2 if the steam is not completely discharged. In addition, since the outlet end of the nozzle 30 is conical, the steam will produce a sharp sound when it is discharged from the nozzle 30, which makes it easier for the operator to further judge the discharge of steam.
