Description

Technical Field

[0001] This utility model belongs to the field of drying technology for layered products, and particularly relates to a power failure protection device and a high-temperature drying oven. Background Technology

[0002] High-temperature drying ovens are a core and crucial element in aluminum-plastic film production lines. Because the ovens can reach temperatures of up to 200 degrees Celsius after being heated by electricity and steam, if the ovens cannot be opened in time to dissipate heat after a power or gas outage, there are certain risks and potential hazards, and the equipment is easily damaged.

[0003] Existing ovens are typically controlled by solenoid valves that operate cylinders, with manual buttons controlling the cylinders. Pressing the lift button raises the cylinder, and pressing the release button retracts it. However, this control method has certain drawbacks. If the power or gas supply is interrupted, the cylinders may not open promptly, preventing the heat inside the oven from dissipating in time, which can lead to burnt aluminum-plastic film and damage to the equipment.

[0004] In order to avoid the above problems, a manual activation device is usually set up in related technologies, but there is a problem of accidental activation of the manual activation device.

[0005] There is an urgent need to provide a power failure protection device and a high-temperature oven to solve the problem of accidental activation of the manual opening device of the high-temperature oven in the above-mentioned technical scenarios.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0007] This disclosure provides a power failure protection device, including: a mounting plate disposed on the outer wall of a high-temperature oven; and

[0008] A manual hydraulic mechanism is mounted on the mounting plate, and the piston rod of the manual hydraulic mechanism abuts against the top cover of the high-temperature oven; and

[0009] A protective cover is fitted onto the mounting plate, with space between the cover and the mounting plate to accommodate a manual hydraulic mechanism; wherein

[0010] The protective cover is connected to the mounting plate via an electromagnet. When the high-temperature oven is powered off, the electromagnet is simultaneously de-energized and demagnetized to open the protective cover, thereby allowing the manual hydraulic mechanism to be operated.

[0011] In one optional embodiment, the electromagnet is disposed at the upper end of the protective cover, and a metal disc is correspondingly disposed on the mounting plate; and

[0012] The electromagnet shares a power supply with the high-temperature oven.

[0013] In one optional embodiment, the lower end of the protective cover is hinged to the mounting plate; and

[0014] A spring is provided on the outer periphery of the metal disc to spring open the protective cover after the electromagnet loses its magnetism.

[0015] In one optional embodiment, the manual hydraulic mechanism includes: a hydraulic cylinder and an operating handle;

[0016] The piston rod is disposed in the hydraulic cylinder body, and the operating handle is connected to the hydraulic cylinder body to drive the hydraulic oil in the hydraulic cylinder body to push the piston rod to extend and retract.

[0017] In one optional embodiment, a heat dissipation notch is provided on the upper sidewall of the protective cover.

[0018] On the other hand, this disclosure provides another power failure protection device, including: a manually operated hydraulic mechanism disposed on the outer wall of a high-temperature oven; and

[0019] A protective cover installed on the outside of the manual hydraulic mechanism; among which

[0020] The protective cover is equipped with an electromagnet. When the high-temperature oven is powered off, the electromagnet is simultaneously de-energized and demagnetized to open the protective cover, thereby allowing the manual hydraulic mechanism to be operated.

[0021] In one optional embodiment, the electromagnet is disposed at the upper end of the protective cover, and a metal disc is correspondingly disposed on the outer wall of the high-temperature oven; and

[0022] The lower end of the protective cover is hinged to the high-temperature oven; and

[0023] A spring is provided on the outer periphery of the metal disc to spring open the protective cover after the electromagnet loses its magnetism.

[0024] In one optional embodiment, the manual hydraulic mechanism includes: a hydraulic cylinder and an operating handle;

[0025] The piston rod is disposed in the hydraulic cylinder body, and the operating handle is connected to the hydraulic cylinder body to drive the hydraulic oil in the hydraulic cylinder body to push the piston rod to extend and retract.

[0026] Thirdly, embodiments of this disclosure provide at least one high-temperature oven, including: the aforementioned power failure protection device; and

[0027] The oven body has a manual hydraulic mechanism installed on its outer wall; and

[0028] The top cover has its flip-up end connected to a manual hydraulic mechanism, and its other end hinged to the oven body; among which...

[0029] The flipping end of the top cover is also connected to an electric cylinder to push the top cover open.

[0030] In one alternative embodiment, a heating element is provided inside the oven body.

[0031] The beneficial effects of this utility model are as follows: the power failure protection device of this utility model covers the manual hydraulic mechanism with a protective cover, thereby preventing the operator from accidentally touching the manual hydraulic mechanism. In addition, the protective cover is fixed by magnetic connection through the electromagnet, so that the protective cover can be opened immediately after the high-temperature oven is accidentally powered off due to the loss of the electromagnet's attraction force, which facilitates the operator to quickly operate the manual hydraulic mechanism. At the same time, the piston rod of the manual hydraulic mechanism is configured to only abut against the top cover of the high-temperature oven. Therefore, the manual hydraulic mechanism will not fully open the top cover of the high-temperature oven, but will only push it open a certain distance, which is conducive to cooling and heat dissipation inside the oven and does not affect the electric opening of the top cover of the high-temperature oven during normal operation.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0041] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, in the figures, the thickness of parts may be exaggerated or reduced for the purpose of effectively depicting the technical content.

[0042] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0043] See Figure 1 , Figure 1 A power failure protection device is shown, comprising: a mounting plate 1 installed on the outer wall of a high-temperature oven; a manual hydraulic mechanism 2 installed on the mounting plate 1; the piston rod 21 of the manual hydraulic mechanism 2 abutting against the top cover 41 of the high-temperature oven; and a protective cover 3 covering the mounting plate 1. The protective cover 3 and the mounting plate 1 enclose a space for the manual hydraulic mechanism 2. The connection between the protective cover 3 and the mounting plate 1 is configured as magnetic attraction, i.e., by installing an electromagnet 31 on the protective cover 3. When the high-temperature oven is unexpectedly powered off, the electromagnet 31 is simultaneously de-energized and loses its magnetic force, thus losing its attraction to the mounting plate 1, causing the protective cover 3 to pop open. Therefore, the manual hydraulic mechanism 2 is covered by the protective cover 3 when not in use, preventing accidental activation. When a power failure occurs, the protective cover 3 pops open, exposing the manual hydraulic mechanism 2. Furthermore, the popping method also serves as a warning, making it easier for operators to detect a power failure.

[0044] See Figure 2In some embodiments, an electromagnet 31 is provided at the upper end of the protective cover 3, and a metal disk 10 is provided at the corresponding position on the mounting plate 1. The protective cover 3 is attracted by the cooperation of the electromagnet 31 and the metal disk 10. The electromagnet 31 is provided at the upper end of the protective cover 3, and the lower end of the protective cover 3 is hinged to the mounting plate 1. The upper end of the protective cover 3 is popped open after the power is turned off.

[0045] See Figure 2 In a preferred embodiment, the electromagnet 31 and the high-temperature oven can share the same power supply through a circuit connection, so that the electromagnet 31 can be demagnetized immediately after the high-temperature oven is powered off.

[0046] See Figure 2 As another preferred embodiment, the power supplies of the two can be configured independently. After the high-temperature oven is powered off, the controller receives the power off signal and controls the electromagnet 31 to de-energize.

[0047] See Figure 2 In some embodiments, a spring 11 is provided on the outer periphery of the metal disk 10 to pop open the protective cover 3 after the electromagnet 31 loses its magnetism. This arrangement is because when the electromagnet 31 is de-energized, its magnetism may not disappear immediately, but gradually weakens. The protective cover 3 may not be able to pop open in time. However, with the spring 11, when the electromagnet 31 loses its magnetism and weakens, the elastic force of the spring 11 is greater than the attraction force of the electromagnet 31, and the protective cover 3 will be popped open immediately, avoiding the problem that the protective cover 3 cannot pop open.

[0048] See also Figure 2 In some embodiments, the manual hydraulic mechanism 2 includes a hydraulic cylinder 20 and an operating handle 22; a piston rod 21 is disposed inside the hydraulic cylinder 20, and the operating handle 22 is connected to the hydraulic cylinder 20 to drive the hydraulic oil inside the hydraulic cylinder 20 to push the piston rod 21 to extend and retract.

[0049] See also Figure 2 As an optional implementation, the piston rod 21 of the manual hydraulic mechanism 2 is configured to only abut against the top cover 41 of the high-temperature oven. Therefore, the manual hydraulic mechanism 2 will not fully open the top cover 41 of the high-temperature oven, but will only push it open a certain distance, which is conducive to cooling and heat dissipation inside the oven, and does not affect the normal electric opening of the top cover 41 of the high-temperature oven.

[0050] See Figure 1 In some embodiments, a heat dissipation notch 30 is provided on the upper side wall of the protective cover 3, so that the heat transferred from the outer wall of the high-temperature oven to the containment space can be dissipated, avoiding overheating in the sealed containment space and damage to the manual hydraulic mechanism 2.

[0051] See Figure 1At least one embodiment also provides a power failure protection device, including: a manual hydraulic mechanism 2 disposed on the outer wall of a high-temperature oven; and a protective cover 3 disposed on the outside of the manual hydraulic mechanism 2; wherein an electromagnet 31 is disposed on the protective cover 3, and when the high-temperature oven is powered off, the electromagnet 31 is simultaneously de-energized and demagnetized to open the protective cover 3, thereby allowing the manual hydraulic mechanism 2 to be operated.

[0052] See Figure 1 In some embodiments, an electromagnet 31 is disposed at the upper end of the protective cover 3, and a metal disc 10 is disposed on the outer wall of the high-temperature oven; the lower end of the protective cover 3 is hinged to the high-temperature oven; and a spring 11 is disposed on the outer periphery of the metal disc 10 to spring open the protective cover 3 after the electromagnet 31 loses its magnetism.

[0053] See Figure 2 In some embodiments, the manual hydraulic mechanism 2 includes a hydraulic cylinder 20 and an operating handle 22; a piston rod 21 is disposed inside the hydraulic cylinder 20, and the operating handle 22 is connected to the hydraulic cylinder 20 to drive the hydraulic oil inside the hydraulic cylinder 20 to push the piston rod 21 to extend and retract.

[0054] See Figure 3 At least one embodiment also provides a high-temperature oven, including the aforementioned power failure protection device; and an oven body 4, the outer wall of which is provided with a position for a manual hydraulic mechanism 2; and a top cover 41, the flipping end of which is connected to the manual hydraulic mechanism 2, and the other end of which is hinged to the oven body 4; wherein the flipping end of the top cover 41 is also connected to an electric cylinder (not shown in the figure) to push the top cover 41 open.

[0055] In some embodiments, a heating element 42 is provided inside the oven body 4.

[0056] In summary, by covering the manual hydraulic mechanism 2 with the protective cover 3, accidental activation by operators is prevented. Furthermore, the protective cover 3 is magnetically connected via the electromagnet 31, allowing it to spring open immediately upon loss of electromagnet 31's attraction in the event of a power outage. This facilitates quick operation of the manual hydraulic mechanism 2. Additionally, the piston rod 21 of the manual hydraulic mechanism 2 is configured to only abut against the top cover 41 of the high-temperature oven. Therefore, the manual hydraulic mechanism 2 will not fully open the top cover 41, but will only push it open a certain distance, which is beneficial for cooling and heat dissipation within the oven and does not affect the normal electric opening of the top cover 41.

[0057] In this document, when it is said that the first component is located on the second component, this can mean that the first component can be directly formed on the second component, or that the third component can be inserted between the first component and the second component.

[0058] In this document, when an element or layer is referred to as “located,” “joined to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly located, joined, connected, attached to, or coupled to the other element or layer, or there may be intermediate elements or layers present. Conversely, when an element is referred to as “directly on another element or layer,” “directly joined to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intermediate elements or layers present. Other terms used to describe relationships between elements should be interpreted in a similar manner (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items.

[0059] In this document, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as “at least one of…” modify the entire list of elements when following a list of elements, rather than individual elements in the list. For example, the expression “at least one of a, b, and c” should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0060] The terminology used herein is for the purpose of describing specific exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may also be intended to include plural forms unless otherwise clearly stated herein. The terms “comprising,” “including,” and “having” are inclusive and thus specify the presence of features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein should not be construed as requiring them to be performed in the specific order discussed or shown, unless specifically identified as such. Additional or alternative steps may be employed.

[0061] As used herein, the phrases “in one embodiment,” “according to one embodiment,” “in some embodiments,” etc., generally refer to the fact that a particular feature, structure, or characteristic following the phrase can be included in at least one embodiment of this disclosure. Therefore, a particular feature, structure, or characteristic can be included in more than one embodiment of this disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms “example,” “exemplary,” etc., are used to “serve as an example, instance, or illustration.” Any implementation, aspect, or design described herein as “example” or “exemplary” is not necessarily to be construed as preferred or superior to other implementations, aspects, or designs. Rather, the use of the terms “example,” “exemplary,” etc., is intended to present concepts in a specific manner.

[0062] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of 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.

[0063] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0064] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0065] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0066] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
