Description

Technical Field

[0001] This utility model belongs to the field of heating furnace technology, specifically, it relates to a furnace door structure. Background Technology

[0002] With the continuous advancement of technology, heating furnaces are being used more and more widely. As a type of baking equipment, heating furnaces provide convenience for food processing. A heating furnace includes a furnace body and a furnace door. The furnace body has a baking cavity, and the furnace body has an opening. During the baking process, the opening is closed by the furnace door to facilitate baking operations. Therefore, as an essential component of the heating furnace, the performance of the furnace door directly affects the heating furnace's performance.

[0003] In the prior art, there are various types of furnace door structures. Most furnace door structures are generally assembled on the heating furnace by sliding assembly. The sliding of the furnace door realizes the opening or closing of the furnace opening. For example, Chinese utility model patent CN221764201U discloses a heating furnace door device. The device includes a door frame with a track fixed on it. The furnace door is slidably assembled on the track. The furnace door is connected to a chain. The other end of the chain extends horizontally through a sprocket and meshes with a drive sprocket. A drive motor is connected to the drive sprocket. The operation of the drive motor can drive the sprocket to rotate, thereby realizing the raising and lowering of the chain. During the raising and lowering process, the chain can drive the furnace door to slide on the track. Therefore, the furnace door moves on the side wall of the heating furnace, thereby realizing the opening or closing of the furnace opening.

[0004] Although the furnace door is moved by the chain to open or close the furnace opening, there are still some inconveniences in its use. Since the furnace opening is located on the side wall of the furnace, and the furnace door only moves along the side wall to the opening, the door merely fits against the furnace opening and cannot be closed by embedding, resulting in poor sealing of the furnace opening.

[0005] Therefore, this utility model provides a furnace door structure that can move along the side wall of the heating furnace to the furnace opening, and can also be embedded in the furnace opening to achieve the purpose of closing, thus ensuring the effectiveness of the furnace door. Utility Model Content

[0006] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A furnace door structure includes a moving carrier plate on which the furnace door is mounted, a linear module, and a drive assembly. The drive assembly can drive the moving carrier plate and the furnace door to move along the linear module to the furnace opening of the heating furnace. The furnace door is slidably assembled with the moving carrier plate, and a clamping assembly is provided on the moving carrier plate. The clamping assembly can drive the furnace door to move relative to the moving carrier plate in a direction perpendicular to the plane of the moving carrier plate, so that the furnace door can be embedded in the furnace opening to achieve the furnace opening closure operation.

[0009] Preferably, in the above structure, the clamping assembly includes a driving cylinder, the power end of the driving cylinder is connected to a connecting rod, and the two ends of the connecting rod are connected to the furnace door through connectors. When the driving cylinder works to drive the connecting rod to move relative to the moving carrier plate, the connecting rod drives the furnace door to move relative to the moving carrier plate and in a plane direction perpendicular to the moving carrier plate through the connectors.

[0010] Preferably, in the above structure, a sliding mechanism is assembled between the moving carrier plate and the furnace door. When the furnace door moves relative to the moving carrier plate, the sliding mechanism enables smooth sliding between the furnace door and the moving carrier plate.

[0011] Preferably, in the above structure, the sliding mechanism includes a linear track mounted on the furnace door and a sliding block mounted on the moving carrier plate, and the linear track and the sliding block are slidably assembled. When the furnace door moves relative to the moving carrier plate, the linear track slides relative to the sliding block.

[0012] Preferably, in the above structure, the linear module is a segmented structure, which includes track I and track II. Track I is installed on the heating furnace, and track II is installed on the moving carrier plate. Track II can move relative to track I. The segmented structure reduces the volume of the linear module.

[0013] Preferably, in the above structure, the linear module further includes a support plate, on which a slider I is mounted and slidably assembled on a track I, and a slider II is also mounted on the support plate, with the track II on the moving support plate slidably assembled with the slider II.

[0014] Preferably, in the above structure, an abutment is fixedly installed at the end of the moving carrier plate, and a receiving member is fixedly installed at one end and on its surface. When the moving carrier plate, the track II, and the furnace door move together on the carrier plate, the carrier plate is stationary. When the abutment on the moving carrier plate abuts against the receiving member at the end of the carrier plate, the moving carrier plate and the furnace door continue to move. The moving carrier plate, the track II, the furnace door, and the carrier plate move together on the track I via the slider I.

[0015] Preferably, in the above structure, the drive assembly includes a connecting frame, which is installed on the heating furnace. A fixed rod is installed between the connecting frames. The drive assembly also includes a rodless cylinder, which is installed on the fixed rod and can move along the length of the fixed rod. The rodless cylinder is connected to the moving carrier plate through a connecting plate. When the rodless cylinder moves along the length of the fixed rod, it can drive the moving carrier plate and the furnace door to move through the connecting plate.

[0016] Preferably, in the above structure, proximity switches are installed on the connecting brackets at both ends of the fixed rod. The proximity switches are connected to the rodless cylinder through the control system. When the rodless cylinder moves along the length of the fixed rod and comes into contact with the proximity switch, the contact switch can control the rodless cylinder to stop working.

[0017] Preferably, in the above structure, a protrusion is provided on the side of the furnace door near the furnace opening. When the clamping assembly drives the furnace door to move towards the side of the furnace opening, the protrusion of the furnace door is embedded in the furnace opening to close the furnace opening.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] (1) In the furnace door structure of this utility model, the furnace door is slidably mounted on the moving carrier plate, and a driving cylinder is installed on the moving carrier plate. The driving cylinder can drive the furnace door to move relative to the moving carrier plate, so that the protrusion on the furnace door can be embedded into the furnace opening to achieve the purpose of closing the furnace opening. Compared with the prior art, the furnace door can only move on the side wall of the heating furnace, which improves the closing effect of the furnace door on the furnace opening. In addition, the smooth movement of the furnace door is ensured by the sliding cooperation of the linear track and the sliding block during the movement of the furnace door relative to the moving carrier plate.

[0020] (2) The furnace door and the moving carrier plate in this utility model can move on the linear module, and the linear module is a segmented structure, consisting of track I, track II and the carrier plate. The volume of the existing module is greatly reduced by track I and track II. When moving, the moving carrier plate, furnace door and track II move relative to the carrier plate first. When moving further, the moving carrier plate, furnace door, track II and the carrier plate move relative to track I. Therefore, the segmented linear module avoids the problem of large volume and inconvenient installation of the whole segment linear module.

[0021] (3) The drive component in this utility model is a rodless cylinder. The rodless cylinder can move along the fixed rod, thereby driving the moving carrier plate and furnace door to move through the connecting plate. In addition, the rodless cylinder, in conjunction with the proximity switch, accurately controls the moving distance of the furnace door, thereby realizing the automated control of the furnace door movement and improving the use effect of the furnace door.

[0038] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0039] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0040] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments. Example

[0041] like Figures 1-4 As shown, this is a schematic diagram of the furnace door structure in this embodiment. The furnace door structure in this embodiment includes a pressing assembly 100. The furnace door is mounted on the pressing assembly 100. The pressing assembly 100 can press the furnace door against the furnace opening of the heating furnace, thereby closing the furnace opening. In this embodiment, the furnace door structure also includes a linear module 200 and a drive assembly 300 mounted between the furnace door and the heating furnace. The drive assembly can drive the pressing assembly 100 and the furnace door to move along the direction of the linear module 200 to the furnace opening. When the furnace door moves to the furnace opening, the pressing assembly 100 can drive the furnace door to embed into the furnace opening, thereby achieving the purpose of closing the furnace opening. Conversely, when it is necessary to open the furnace opening, the pressing assembly 100 can first drive the furnace door away from the furnace opening, and then the drive assembly 300 can drive the pressing assembly 100 and the furnace door to move along the linear module 200, so that the furnace door moves away from the furnace opening.

[0042] like Figure 4 , Figure 6 as well as Figure 9 As shown, in this embodiment, the side of the furnace door closest to the furnace opening is a protrusion. When the pressing assembly 100 drives the furnace door to move towards the furnace opening, the protrusion of the furnace door is embedded in the furnace opening to close the furnace opening. When the pressing assembly 100 drives the furnace door to move away from the furnace opening, the protrusion of the furnace door moves away from the furnace opening to open the furnace opening.

[0043] like Figure 1 as well as Figure 4 As shown, when the furnace door needs to be closed, the furnace door moves in the following direction: first, the furnace door moves along the linear module 200 to the furnace opening, and then the clamping assembly 100 drives the furnace door to move along the direction perpendicular to the furnace opening plane until the furnace door is embedded in the furnace opening to achieve the purpose of closing the furnace opening.

[0044] like Figure 1As shown, the pressing assembly 100 in this embodiment includes a moving carrier plate 101. The furnace door is slidably mounted on the side wall of the moving carrier plate 101, and the furnace door can move along the plane perpendicular to the moving carrier plate 101 so as to allow the furnace door to be inserted into the furnace opening to close the furnace opening or to move the furnace door away from the furnace opening to open it.

[0045] like Figure 8 As shown, in this embodiment, a fixed plate is installed on the moving carrier plate 101, and a driving cylinder 102 is fixedly connected to the fixed plate. A connecting rod 103 is connected to the power end of the driving cylinder 102, and connecting parts 104 are connected to both ends of the connecting rod 103. The connecting parts 104 are fixedly connected to the furnace door. Therefore, when the driving cylinder 102 works, it can drive the connecting rod 103 to move away from or towards the moving carrier plate 101, thereby driving the furnace door to move towards or away from the moving carrier plate 101 through the connecting parts 104. This allows the furnace door to be inserted into the furnace opening to achieve the purpose of closing the furnace opening, or to move away from the furnace opening to achieve the purpose of opening the furnace opening. When the furnace door needs to be inserted into the furnace opening to achieve the purpose of closing the furnace opening, the direction of movement of the furnace door is as follows: Figure 9 As shown.

[0046] like Figure 8 As shown, in order to ensure the smooth movement of the furnace door, a sliding mechanism is also installed between the moving carrier plate 101 and the furnace door in this embodiment. The sliding mechanism makes the movement of the furnace door relative to the moving carrier plate 101 smoother. In this embodiment, the sliding mechanism includes a sliding block 106 fixedly installed on the moving carrier plate 101 and a linear track 105 installed on the furnace door. The sliding block 106 and the linear track 105 are slidably assembled. Therefore, when the driving cylinder 102 drives the furnace door to move relative to the moving carrier plate 101, the linear track 105 moves relative to the sliding block 106 to ensure the smooth movement of the furnace door.

[0047] It is worth noting that, such as Figure 8 as well as Figure 9 As shown, in order to avoid interference caused by the drive cylinder 102 when the furnace door moves toward the moving carrier plate 101, in this embodiment, a groove is provided on the surface of the furnace door. When the furnace door moves toward the moving carrier plate 101, the drive cylinder 102 enters the groove, thus avoiding the problem of the drive cylinder 102 interfering with the movement of the furnace door.

[0048] Therefore, under the action of the drive assembly 300, the furnace door in this embodiment can move along the direction of the linear module 200 to the furnace opening of the heating furnace. On the other hand, the drive cylinder 102 in the pressing assembly 100 can drive the furnace door to move relative to the moving carrier plate 101, thereby making the furnace door embedded in the furnace opening to achieve the purpose of closing the furnace opening. The furnace door in this embodiment achieves the purpose of closing the furnace opening through multi-directional movement, ensuring the closing effect of the furnace door structure on the heating furnace, thereby ensuring the use effect of the heating furnace. Example

[0049] like Figure 5 as well as Figure 7 As shown, the furnace door structure in this embodiment, based on embodiment 1, includes a linear module 200 comprising a track I 201, which is mounted on the side wall of the heating furnace. In this embodiment, a slider I 202 is slidably mounted on the track I 201, and the slider I 202 can slide along the length of the track I 201. In this embodiment, a support plate 203 is fixedly connected to the slider I 202. Since the slider I 202 can move on the track I 201, the support plate 203 can slide along the track I 202. The track I 201 moves along its length. In this embodiment, a slider II 204 is fixedly installed on the support plate 203, and the linear module 200 also includes a track II 205. In this embodiment, the track II 205 is fixedly installed on the moving carrier plate 101, and the track II 205 and the slider II 204 are slidably assembled. Therefore, when the moving carrier plate 101, the track II 205, and the furnace door move as a whole, the moving carrier plate 101 and the track II 205 first move relative to the slider II 204 on the support plate 203, at which time the support plate 203 is in a stationary state.

[0050] In addition, such as Figure 5 , Figure 7 as well as Figure 8 As shown, in this embodiment, an abutment 101a is fixedly installed at the end of the moving carrier plate 101, and a receiving member 203a is fixedly installed on one end and its surface of the carrier plate 203. When the moving carrier plate 101, the track II 205, and the furnace door move together on the carrier plate 203, the carrier plate 203 is stationary. After the abutment 101a on the moving carrier plate 101 abuts against the receiving member 203a at the end of the carrier plate 203, the moving carrier plate 101 and the furnace door continue to move. At this time, the moving carrier plate 101, the track II 205, the furnace door, and the carrier plate 203 move together on the track I 201 via the slider I 202 until the furnace door reaches the destination. Figure 4 At the furnace opening shown, the drive cylinder 102 on the moving carrier plate 101 then operates to move the furnace door away from the moving carrier plate 101, causing the furnace door to be embedded in the furnace opening for closing the furnace opening.

[0051] Conversely, when it is necessary to open the furnace opening, the drive cylinder 102 first moves the furnace door closer to the moving carrier plate 101, causing the furnace door to separate from the furnace opening. Then, the drive assembly 300 drives the moving carrier plate 101 and the furnace door to move as a whole. The moving carrier plate 101, the furnace door, and the track II 205 move relative to the support plate 203 until the abutment 101a on the other side of the moving carrier plate 101 abuts against the receiving part 203a on the support plate 203. Then, the moving carrier plate 101 continues to move. At this time, the moving carrier plate 101, the furnace door, the track II 205, and the support plate 203 move as a whole on the track I 201 until the furnace door completely leaves the furnace opening, thus achieving the purpose of opening the furnace opening.

[0052] In this embodiment, the linear module 200 is a segmented structure composed of track I 201 and track II 205. Therefore, the linear module 200 in this embodiment avoids the problems caused by the integral track in the prior art. Furthermore, the abutting action between the abutting member 101a on the moving carrier plate 101 and the bearing member 203a on the carrier plate 203 enables track II 205 to move relative to track I 201, thereby reducing the volume of the linear module 200 and avoiding the problem of excessively large track volume in the prior art for furnace door sliding, thus ensuring the effectiveness of furnace door movement. Example

[0053] like Figure 3 as well as Figure 7 As shown, the furnace door structure in this embodiment is based on Embodiments 1 and 2. The drive assembly 300 includes a connecting frame 301, which is fixedly installed on the heating furnace. A fixing rod 302 is installed between the connecting frames 301, and a rodless cylinder 303 is installed on the fixing rod 302. The rodless cylinder 303 is connected to a connecting plate 304, which is connected to the moving carrier plate 101. In this embodiment, the rodless cylinder 303 can move along the length of the fixing rod 302, and during the movement, the rodless cylinder 303 drives the moving carrier plate 101 to move through the connecting plate 304. When it is necessary to close the furnace opening, the rodless cylinder 303 moves through the connecting plate 304. Plate 304 drives the moving carrier plate 101 and the furnace door to move relative to the bearing plate 203 until the abutting part 101a on the moving carrier plate 101 abuts against the receiving part 203a on the bearing plate 203. Then, rodless cylinder 303 continues to drive the moving carrier plate 101 to move through connecting plate 304. At this time, the moving carrier plate 101, the furnace door, and the track II 205 and the bearing plate 203 move relative to track I 201 until the furnace door reaches the furnace opening. Then, the driving cylinder 102 drives the furnace door to move relative to the moving carrier plate 101 so that the furnace door can be embedded in the furnace opening to achieve the purpose of closing the furnace opening. In any case, the process of opening the furnace opening is as described above, and will not be repeated in this embodiment.

[0054] Additionally, it should be noted that in this embodiment, proximity switches are installed on the connecting brackets 301 at both ends of the fixed rod 302. The proximity switches are connected to the rodless cylinder 303 through the control system. When the rodless cylinder 303 moves along the length of the fixed rod 302 and abuts against the proximity switch, the rodless cylinder 303 can be stopped. Therefore, the movement distance of the rodless cylinder 303 can be precisely controlled by the proximity switch, and thus the movement distance of the furnace door on the moving carrier plate 101 can be precisely controlled, so as to automatically control the movement distance of the furnace door and achieve the purpose of opening or closing the furnace opening.

[0055] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
