Description

Technical Field

[0001] The present utility model relates to the technical field of door structures, and specifically refers to an automatic sealing door, a sealing device and a processing equipment. Background Art

[0002] In the contemporary fields of industrial automation and precision manufacturing, the requirements for the sealing performance of the working environment are becoming increasingly stringent. Especially in sensitive environments involving precision instruments, semiconductor production, biopharmaceuticals, and chemical processing, a high degree of sealing of the door structure has become an indispensable condition. Traditional door sealing technologies, such as adhering sealing rings, can provide relatively reliable sealing effects in rotatable opening and closing doors, but in horizontally moving opening and closing door structures, this sealing method seems inadequate.

[0003] For horizontally moving opening and closing doors, due to their unique opening and closing mechanisms, more complex requirements are put forward for the design of the sealing strip. First of all, in order to ensure the smoothness of the door during movement and avoid interference, the design of the sealing strip cannot be too prominent, which directly results in that when the door is closed, the sealing strip cannot deform enough to completely fill the gap between the door and the frame, thus affecting the overall sealing effect and allowing external factors such as dust, gas, and liquid to potentially penetrate into the working area and pollute the internal environment.

[0004] In addition, the existing installation methods of the sealing strip are usually limited to the first and last ends in the moving direction of the door, and installing the sealing strip on the side of the door faces the problem of large friction during horizontal movement. This friction will not only cause rapid wear of the sealing strip, but may even lead to the detachment of the sealing strip, which not only increases the maintenance cost, but may also cause interruptions and safety risks during the production process.

[0005] For a long time, the problem of lateral gap sealing of horizontally moving opening and closing doors has always been a difficult problem in the field of industrial design. This problem is not only related to the sealing performance of the processing environment, but also directly affects the product quality, the safety of operators, and environmental protection. However, there has been no effective solution to this problem in the industry. Summary of the Invention

[0006] Therefore, the technical problem to be solved by the present utility model is to overcome the problem of low lateral sealing performance of horizontally opening and closing doors in the prior art, and provide an automatic sealing door, a sealing device and a processing equipment.

[0007] To solve the above technical problems, the present utility model provides an automatic sealing door, which comprises: a door frame, with an installation opening in the middle of the door frame; four guide rods, symmetrically arranged on both sides of the installation opening in a first direction, and all extending in a second direction. Any of the guide rods includes a rod body and a chute. The chute is arranged inside the rod body and includes a horizontally communicating part and a pressing part. The pressing parts are all arranged at one end of the guide rod facing the middle of the installation opening, and in the thickness direction of the door frame, the pressing parts extend obliquely from the horizontally communicating part towards the door frame; a door body mechanism, which includes two door panels and four moving shafts. The two door panels move relative to each other in the second direction. On both sides of any door panel in the first direction, two moving shafts are respectively connected. The moving shafts are slidably embedded in the chutes. A sealing strip is provided at the edge of the door panel. When the moving shafts slide in the horizontally communicating part, the sealing strip is spaced from the door frame. When the moving shafts move along the pressing part, the sealing strip gradually approaches the door frame until it presses against the door frame.

[0008] In an embodiment of the present utility model, it further includes a driving mechanism, and the two door panels are respectively connected to the driving mechanism to move relatively closer to / away from each other.

[0009] In an embodiment of the present utility model, the driving mechanism includes a rotary driver, two rotating shafts, four driving wheels and two conveyor belts. The two rotating shafts are arranged at both ends of the door frame in the second direction, and any of the rotating shafts extends along the first direction. One of the rotating shafts is connected to the rotary driver. The four driving wheels are respectively arranged at both ends of the two rotating shafts and rotate synchronously with the rotating shafts. The two conveyor belts are respectively arranged on both sides of the door frame in the first direction, extending in the second direction, and their two ends are respectively sleeved with one driving wheel to form a closed loop structure.

[0010] In an embodiment of the present utility model, a connecting block is provided on the door body. The connecting blocks of the two door bodies are respectively connected to two layers of the conveyor belt in its thickness direction, and the connecting blocks of different door bodies move in opposite directions.

[0011] In an embodiment of the present utility model, it further includes a control system, and the driving mechanism is connected to the control system.

[0012] In an embodiment of the present utility model, the control system further includes a plurality of regulating buttons.

[0013] In an embodiment of the present utility model, a sound insulation cotton is provided on the door panel. The sound insulation cotton is arranged around the installation opening. When the moving shafts move along the pressing part, the sealing strip gradually approaches the sound insulation cotton until it presses against the sound insulation cotton.

[0014] In an embodiment of the present utility model, it further includes an installation surface, and the door frame is connected to the installation surface.

[0015] The present utility model also provides a sealing device, which includes the above-mentioned automatic sealing door.

[0016] The present utility model also provides a processing device, which includes the above-mentioned automatic sealing door.

[0017] The above technical solution of the present utility model has the following advantages compared with the prior art:

[0018] For the automatic sealing door, sealing device and processing device of the present utility model, the moving direction of the door body is guided through the specially designed sliding groove on the guide rod, realizing the three-dimensional movement of the door body. Thus, when the door body is in the closed state, the sealing strip thereon can be pressed against the door frame, thereby achieving a high extrusion sealing effect. And when the door body is in the moving state, there can be an interval between the sealing strip and the door frame, thus avoiding the risk of wear and shedding of the sealing strip due to repeated contact and friction during their relative movement. Compared with conventional sealing doors and their related structures, the present application has the remarkable advantages of high sealing effect and long service life.

Detailed implementation manners

[0026] The present utility model will be further described below in conjunction with the drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the embodiments cited are not intended to limit the present utility model.

[0027] Embodiment 1

[0028] This embodiment provides an automatic sealing door, which includes: a door frame 100, with an installation opening provided in the middle of the door frame 100; four guide rods 300, symmetrically arranged on both sides of the installation opening in the first direction X, and all extending along the second direction Y. Any one of the guide rods 300 includes a rod body 310 and a chute 320. The chute 320 is arranged inside the rod body 310, and includes a horizontally communicating horizontal part 321 and a pressing part 322. The pressing part 322 is arranged at one end of the guide rod 300 facing the middle of the installation opening. And in the thickness direction of the door frame 100, the pressing part 322 extends obliquely from the horizontal part 321 towards the door frame 100; a door body mechanism 200, the door body mechanism 200 includes two door panels 210 and four moving shafts 230. The two door panels 210 move relative to each other along the second direction Y. On both sides of any one of the door panels 210 in the first direction X, two moving shafts 230 are respectively connected. The moving shafts 230 are slidably embedded in the chute 320 and move along the chute 320. A sealing strip is provided at the edge of the door panel 210. When the moving shaft 230 slides in the horizontal part 321, the sealing strip is spaced from the door frame 100. When the moving shaft 230 moves along the pressing part 322, the sealing strip gradually approaches the door frame 100 until it presses against the door frame 100.

[0029] The automatic sealing door described in this embodiment guides the moving direction of the door body through the specially designed sliding groove 320 on the guide rod 300, realizing the three-dimensional movement of the door body. Thus, when the door body is in the closed state, the sealing strip on it can be pressed against the door frame 100, thereby achieving a high extrusion sealing effect. When the door body is in the moving state, there is a gap between the sealing strip and the door frame 100, thus avoiding the risk of wear and tear of the sealing strip due to repeated contact and friction during their relative movement. Compared with conventional sealing doors and their related structures, this application has the remarkable advantages of high sealing effect and long service life. At the same time, its structure is delicate, the cost is low, and it is easy to operate, having a broad application prospect in this industry.

[0030] It should be noted that for the convenience of description, in this embodiment, the width direction of the automatic sealing door is defined as the first direction X, the length direction of this automatic sealing door (i.e., the moving direction of the door body) is defined as the second direction Y, and the thickness direction of this device is defined as the third direction Z. Among them, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other in pairs, and the first direction X and the second direction Y are located in the same plane.

[0031] See Figure 1 As shown, this embodiment further includes an installation surface 500. The door body mechanism 200 is connected to the installation surface 500 through the door frame 100, and the door frame 100 is detachably connected to the installation surface 500. Further, a material transmission hole is provided at the center of the installation surface 500 in this embodiment. The door frame 100 is set as a frame body having the same shape as the material transmission port, and it is connected to the installation surface 500 around the material transmission port. Based on this, the opening and closing of the material transmission port can be realized as the door body opens and closes.

[0032] See Figure 2 As shown, this embodiment includes two door bodies arranged along the second direction Y, and the two door bodies move relative to each other. Specifically, both sides of any door body are connected to the door frame 100 through the guide rod 300. In this embodiment, four guide rods 300 are specifically provided, and both sides of the door body are respectively slidably connected to the corresponding guide rod 300, thereby guiding the moving direction of the door body through the guide rod 300. The four guide rods 300 in this embodiment are arranged in position according to actual use requirements, and their specific structures are the same. Therefore, one of the guide rods 300 is taken as an example to introduce the structure here.

[0033] See Figure 3As shown, in this embodiment, the rod body 310 is preferably a strip-shaped cube with a certain thickness, and its extension length in the second direction Y is not less than half of the extension length of the door frame 100, thereby providing sufficient length for the actual moving stroke of the door body. In the thickness direction of the rod body 310, the sliding grooves 320 are all arranged in the middle of the rod body 310. Further, the sliding grooves 320 in this embodiment are all preferably through grooves, and the horizontal part 321 thereof is in the same direction as the extension direction of the rod body 310, and the pressing part 322 extends obliquely toward the door frame 100 from one end of the horizontal part 321 close to the closed position of the door body. Based on the above structure, since the rod body 310 has a certain thickness, there is a certain interval distance between the door body and the door frame 100 when the door body slides in the horizontal part 321, so that the sealing strip on the door body will not have relative sliding friction with the door frame 100, thereby realizing the protection effect on the sealing strip during the moving process; and when the door body moves in the pressing part 322, it can gradually move toward the door frame 100 under the inclined guiding action of the pressing part 322, and when the door body moves to the end of the extension part, the sealing strip can be closely attached to the door frame 100, thereby realizing a stable sealing effect.

[0034] See Figure 4 and Figure 5 As shown, the automatic sealing door in this embodiment further includes a driving mechanism 400. The two door panels 210 are respectively connected to the driving mechanism 400 to move relatively closer to / away from each other. Further, the driving mechanism 400 includes a rotary driver 410, two rotating shafts 420, four driving wheels 430 and two conveyor belts 440. The two rotating shafts 420 are arranged at both ends of the door frame 100 along the second direction Y, and any one of the rotating shafts 420 extends along the first direction X. One of the rotating shafts 420 is connected to the rotary driver 410. The four driving wheels 430 are respectively arranged at both ends of the two rotating shafts 420 and rotate synchronously with the rotating shafts 420. The two conveyor belts 440 are respectively arranged on both sides of the door frame 100 in the first direction X, extend along the second direction Y, and both ends thereof are respectively sleeved with one driving wheel 430 to form a closed loop structure. Further still, a connecting block 220 is provided on the door body. The connecting blocks 220 of the two door bodies are respectively connected to two layers in the thickness direction of the conveyor belt 440, and the connecting blocks 220 of different door bodies move in opposite directions. Based on the above structure, in this application, only one rotary driver 410 can simultaneously realize the relative movement process of the two door bodies, which not only simplifies the operation process, but also greatly reduces the cost, and at the same time can reduce the volume of this automatic sealing door, thereby achieving the purpose of improving the applicable range of this automatic sealing door. Specifically, the rotary driver 410 in this embodiment is preferably a rotary motor, and the present utility model does not make specific limitations thereto.

[0035] In this embodiment, in order to improve the sound insulation effect of the Seeking Marquis, a sound insulation cotton is provided on the door panel 210. The sound insulation cotton is arranged around the installation opening. When the moving shaft 230 moves along the pressing portion 322, the sealing strip gradually approaches the sound insulation cotton until it is squeezed with the sound insulation cotton.

[0036] This embodiment further includes a control system. The driving mechanism 400 is connected to the control system. A plurality of regulating buttons 510 are provided on the control system. All the regulating buttons 510 are connected to the installation surface 500 for the convenience of operation by the operator. Further, in the actual production and processing process, the operator can perform real-time regulation on the above structure through the control system, thereby improving the flexibility of use of this sealing door. Parameters can also be preset through the control system, thereby improving the automation degree of this sealing door.

[0038] This embodiment provides a sealing device, which includes the automatic sealing door described in Embodiment One.

[0039] Embodiment Three

[0040] This embodiment provides a processing device, which includes the automatic sealing door described in Embodiment One.

[0041] In summary, for the automatic sealing door, sealing device and processing device of the present utility model, the moving direction of the door body is guided through the specially designed sliding groove 320 on the guide rod 300, realizing the three-dimensional movement of the door body. Thus, when the door body is in the closed state, the sealing strip thereon can be pressed against the door frame 100, further achieving a high extrusion sealing effect. When the door body is in the moving state, there can be an interval between the sealing strip and the door frame 100, thereby avoiding the risk of wear and shedding of the sealing strip due to repeated contact and friction during the relative movement of the two. Compared with conventional sealing doors and their related structures, this application has the significant advantages of high sealing effect and long service life. At the same time, its structure is delicate, the cost is low, and it is easy to operate, having a broad application prospect in this industry.
