Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of vacuum drying equipment, in particular to a parts vacuum drying device. Background Art
[0002] In existing industrial production technology, drying of parts is a crucial link. In order to ensure the quality and performance of parts, it is often necessary to dry the parts, especially after some specific process flows, such as oxidation treatment. At present, the common drying method is to heat the vacuum chamber, which can prevent chemical reactions.
[0003] Specifically, the principle of vacuum chamber heating and drying is to use heat energy to remove moisture from the surface of parts. In a vacuum environment, heating can evaporate moisture more effectively while preventing chemical reactions between parts and oxygen in the air, such as oxidation reactions. This method not only improves drying efficiency, but also ensures the surface quality of parts. However, heating the entire vacuum chamber consumes a lot of energy, resulting in high energy consumption. In addition, when the user opens the door, if the safety operating specifications are not followed, it is easy to be burned by the high temperature inside the vacuum chamber. Utility Model Content
[0004] In view of the above problems, the utility model discloses a parts vacuum drying device, comprising a vacuum chamber, wherein a door is provided on any side of the vacuum chamber, and a sealing member is provided in the opening and closing area of the door; a placement plane and a dryer are provided in the vacuum chamber; the dryer has a drying head, which faces the placement plane, and the dryer also extends a fixed end, which is slidably connected in the dryer; wherein the dryer slides in the vacuum chamber, and the sliding of the dryer does not change the direction of the drying head.
[0005] In some exemplary technical solutions, a sliding track is further provided in the vacuum chamber, and the fixed end is slidably connected to the sliding track; the sliding track is arranged parallel to the placement plane.
[0006] In some exemplary technical solutions, the sliding track includes a longitudinal track arranged along the inner wall of the vacuum chamber, a first slider is slidably connected to the longitudinal track, and a transverse track is arranged on the other side of the slider; the fixed end is slidably connected to the transverse track.
[0007] In some exemplary technical solutions, the fixed end is connected to a second slider, which is inserted into the transverse track; the second slider is also connected to a chain, which is wound around the transverse track; wherein driving gears matching the chain are provided at both ends of the transverse track, and the chain is sleeved on the driving gears.
[0008] In some exemplary technical solutions, the placement plane is arranged on the bottom plane of the vacuum chamber; one side edge of the cabin door is hinged to the bottom plane of the vacuum chamber, and the cabin door forms an extension surface of the placement plane when it is opened.
[0009] In some exemplary technical solutions, a first clip is also provided on the opposite side of the hinged side of the cabin door, and the outer wall of the vacuum chamber is provided with a second clip that matches the first clip; when the first clip and the second clip are in a clamped state, the distance between the cabin door and the outer wall of the vacuum chamber is less than the thickness of the seal.
[0010] In some exemplary technical solutions, a clamping piece is arranged around the placement plane, the clamping piece is telescopically connected to the bottom of the vacuum chamber, and the top of the clamping piece has a protrusion extending above the placement plane.
[0011] In some exemplary technical solutions, the sealing member is a rubber strip.
[0012] The beneficial effect of the utility model is that the dryer is arranged to partially dry the parts to be dried, and the sliding track is arranged in the vacuum chamber to control the movement of the dryer above the parts to be dried, thereby completing the overall drying of the parts to be dried. In some examples, the sliding track includes a transverse track and a longitudinal track, which controls the movement of the dryer in a two-dimensional plane to achieve the drying function.
[0013] Compared with the drying method of heating the vacuum chamber as a whole in the prior art, on the one hand, it reduces energy consumption; on the other hand, since local heating will not cause the overall temperature of the chamber to rise, opening the door at the end of drying will not cause high temperature damage to the user.

The purpose and other advantages of the utility model can be realized and obtained by the structures indicated in the description, claims and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] First embodiment
[0026] In this example, a parts vacuum drying device is disclosed, referring to Figure 1-3 , including a vacuum chamber 1, wherein a hatch 101 is provided on any side of the vacuum chamber 1, and a sealing member 102 is provided in the opening and closing area of the hatch 101; a placement plane 103 and a dryer 4 are provided in the vacuum chamber 1; the dryer 4 has a drying head 201, and the drying head 201 faces the placement plane 103, and the dryer 4 also extends a fixed end 202, and the fixed end 202 is slidably connected in the dryer 4; wherein, the dryer 4 slides in the vacuum chamber 1, and the sliding of the dryer 4 does not change the direction of the drying head 201.
[0027] In this example, the dryer 4 has a drying head 201, and the drying head 201 is directly facing the placement plane 103, which is the position where the part is placed when the part is placed. When the dryer 4 slides in the vacuum chamber 1, the drying head 201 can perform local drying. In addition, the fixed end 202 of the dryer 4 is slidably connected in the dryer 4, which allows the dryer 4 to slide freely in the vacuum chamber 1, while the orientation of the drying head 201 remains unchanged, so that it can be moved to any position in the vacuum chamber 1 to perform local drying of the part, whether it is the edge or the center of the part, it can be dried evenly and effectively. Finally, when all parts of the part have been locally dried, the entire part has completed comprehensive drying, and there is no need to heat up the vacuum chamber 1 as a whole.
[0028] Second embodiment
[0029] Based on the above implementation, in the second embodiment, by further referring to Figure 2 In this example, a sliding track 2 is added inside the vacuum chamber 1 , and the fixed end 202 can slide on the sliding track. In addition, the sliding track 2 is parallel to the placement plane 103 .
[0030] In detail, the slide rail comprises two parts, one part is a longitudinal rail 203 arranged along the inner wall of the vacuum chamber 1 , on which a first slider 205 is provided; the other part is a transverse rail 204 fixed on the other side of the first slider 205 .
[0031] As mentioned above, the fixed end 202 can move two-dimensionally inside the vacuum chamber 1, and the sliding track 2 is parallel to the placement plane 103. When the placement plane 103 is provided with parts to be dried, the dryer 4 can be kept moving above the placement plane 103 to dry the parts.
[0032] During operation, after the parts to be dried are placed on the placement plane 103, the fixed end 202 slides along the transverse track 204, and then slides along the longitudinal track 203. During the movement, the dryer 4 continues to dry the parts to be dried. Different from the method of globally heating the drying bin in the prior art, in this example, the dryer 4 can locally dry the parts to be dried until the drying process is completed. While reducing energy consumption, it prevents high temperature from hurting people. It also simplifies the maintenance and maintenance of the equipment. Since each component is modularly designed, it can be quickly replaced or repaired in the event of failure or wear.
[0033] In some specific examples, the fixed end 202 is connected to a second slider 209, and the second slider 209 is installed in the transverse track 204. In addition, the second slider 209 is also connected to a chain 206 wound around the transverse track 204. Specifically, the second slider 209 is provided with a central through hole, the dryer 4 is cylindrical, and the dryer 4 is fixedly arranged in the central through hole.
[0034] like Figure 2 In the structure shown, the driving gear 207 is respectively engaged with the chain 206. When working, the longitudinal track 203 is externally connected to a driving motor, and the driving motor drives the first slider 205 to drive the transverse track 204 to move longitudinally. Every time it moves a certain distance, the hinge drives the second slider 209 to complete a reciprocating motion on the transverse track 204 to achieve drying of the parts to be dried.
[0035] Third embodiment
[0036] Based on the above embodiments, for a better understanding, please refer to Figure 3 Understand this example. In this embodiment, the placement plane 103 is set on the lower plane of the vacuum container, thereby ensuring the stable positioning of the parts to be dried in the vacuum environment. At the same time, the side edge of the hatch 101 is connected to the lower plane of the vacuum chamber 1 by a hinge. When the hatch 101 is opened, it faces Figure 3 As shown in the figure, the cabin door 101 is opened from the bottom and actually forms an extension surface of the placement plane 103. In addition, this extension surface design also helps to improve work efficiency. Users can quickly extend items from the cabin door 101 to the placement plane 103 without interrupting the workflow, thereby saving time and energy.
[0037] exist Figure 3 In the specific example shown, at least one inclined block 104 inclined toward the vacuum chamber 1 is provided on the inner wall of the hatch 101. After the user places the dried parts on the inclined block 104, the inclined block 104 naturally slides onto the placement plane 103 under the action of gravity.
[0038] Fourth embodiment
[0039] Based on the aforementioned embodiments, especially the third embodiment, in this example, continue to refer to Figure 3It is understood that, relative to the previous embodiment, in this example, in addition to the hinged side of the hatch 101, the other side edge of the hatch 101 is also provided with a first fastener. At the same time, a second snap joint matching the first snap joint is also provided on the outer side wall of the vacuum chamber 1. When the first snap joint 105 and the second snap joint 106 are snapped, the distance between the hatch 101 and the outer wall of the vacuum chamber 1 is less than the thickness of the sealing member 102. It is not difficult to understand that the first snap joint 105 and the second snap joint 106 will compress the sealing member 102 after being snapped together, thereby maintaining the sealing effect of the vacuum chamber 1.
[0040] exist Figure 3 In the example shown, the first clamping member 105 is a strip structure with a bending structure, and the second clamping member 106 is a rectangular block with a groove 1061 arranged on the outer wall surface of the vacuum chamber 1. The end of the strip structure matches the groove 1061, and the end of the strip structure is fixed after being inserted into the groove 1061.
[0041] In other embodiments, a clamping member 208 is disposed around the placement plane 103, the clamping member 208 is telescopically connected to the bottom of the vacuum chamber 1, and the top of the clamping member 208 has a protrusion extending above the placement plane 103. It is not difficult to understand that the clamping space formed by the protrusion and the placement plane 103 fixes the parts to be dried.
[0042] Fifth embodiment
[0043] In the above examples, the sealing member 102 is a rubber strip.
[0044] When using the device disclosed in the above embodiment to dry parts, first open the door 101 of the vacuum chamber 1. The door 101 is connected to the vacuum chamber 1 by a hinge and can be easily opened downward. After opening the door 101, place the parts to be dried on the inclined block 104. Under the action of gravity, the parts will naturally slide onto the placement plane 103, and then close the door 101 to ensure that the sealing member 102 is pressed by the door 101 and the first and second clamping members 106 to maintain the sealing effect of the vacuum chamber 1.
[0045] Start the drying device in the vacuum chamber 1. At this time, the fixed end 202 starts to slide on the sliding track 2, driving the dryer 4 to move two-dimensionally inside the vacuum chamber 1. Specifically, the fixed end 202 will first move along the transverse track 204 to complete a round of reciprocation to partially dry the parts to be dried. The above process can be achieved by the engagement of the chain 206 and the driving gear 207. The rotation of the driving gear 207 drives the chain 206, and the chain 206 then drives the second slider 209 on the fixed end 202 to move on the transverse track 204.
[0046] After completing a round of drying, the fixed end 202 stops moving on the transverse track 204 and starts sliding along the longitudinal track 203. This is achieved by an external drive motor, which provides power to the first slider 205 to move on the longitudinal track 203.
[0047] During the movement of the dryer 4, the drying head 201 always faces the placement plane 103, and the parts are dried continuously and evenly. This local drying method not only reduces energy consumption, but also, since the dryer 4 can move two-dimensionally in the vacuum chamber 1, it can cover any position on the placement plane 103, ensuring that each part can be fully dried. In addition, after the drying is completed, the user will not be injured by high temperature when opening the cabin door 101.
[0048] In the above example, the drying head 201 of the dryer 4 is heated by an external heating element, and the heating temperature can be adjusted as needed. The specific device can be any device in the prior art that can achieve the local heating function, and will not be described in detail. In addition, the bottom of the vacuum chamber 1 is also connected to a vacuum exhaust device 3 for evacuating the vacuum. Similarly, the vacuum exhaust device 3 is also well-known and will not be described in detail here.
[0049] In some examples, the vacuum chamber 1 further has an observation window 107, and during the drying process, the drying status of the parts can be checked at any time through the observation window 107. If it is found that the parts have been dried or the drying process needs to be interrupted, the operation of the drying device can be stopped at any time, and the cabin door 101 can be opened to take out the parts.
[0050] In some examples, after drying one side, the other side can be turned over to dry the other side. A second set of sliding tracks 2 and dryer 4 can also be provided below. The specific principle of the above method is consistent with the above embodiment and will not be repeated.
[0051] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
