Description

Technical Field

[0001] The invention relates to the technical field of rubber strip sealed fast-moving doors, in particular to a rubber strip sealed fast-moving door track. Background Art

[0002] Rapid doors are industrial doors with high efficiency, fast speed and good sealing performance. Strip-sealed rapid doors are widely used in industrial fields, such as automobile manufacturing, mechanical processing, electronic appliances, food processing and other industries. Rapid doors can be used in workshops, warehouses, logistics channels and other places to quickly isolate different work areas and improve production efficiency and the quality of the working environment.

[0003] As an important component of the rapid door, the rapid door track is mainly used to assist the stable lifting and retraction of the door curtain. During the use of the rapid door track, in order to ensure the sealing effect after the rapid door is closed, a sealing strip is provided on the track. The sealing purpose is achieved by the offsetting effect of the sealing strip and the door curtain. During the sealing process of the sealing strip, the gap between the sealing strip and the door curtain is difficult to control. If the gap between the door curtain and the sealing strip is too small, it will produce resistance to the lifting and lowering of the door curtain, affecting the smooth winding and releasing of the door curtain. If the gap between the door curtain and the sealing strip is too large, it will have a certain impact on the sealing of the door curtain after closing on the rapid door. For this reason, we propose a strip-sealed rapid door track. Summary of the invention

[0033] It should be noted here that: during the use of the rapid door track, through the mutual cooperation of the lifting assembly, the transmission assembly and the sealing assembly, the sealing strip 804 on the mounting plate 803 can not only prevent the door curtain 103 from contacting and generating resistance to the lifting and lowering movement of the door curtain 103 during the process of rolling up and releasing the door curtain 103, thereby facilitating the stable lifting and lowering operation of the door curtain 103; and during the closing process of the door curtain 103, through transmission, the sealing strip 804 on one side of the mounting plate 803 can be abutted against the outer side of the door curtain 103. Through the abutment between the sealing strip 804 and the door curtain 103, the closed door curtain 103 is sealed in the form of a strip to ensure the sealing of the rapid door after closing.

[0034] Preferably, the sealing assembly includes a mounting groove 801 provided on the slide rail 102, a strip plate 802 is connected to the mounting groove 801 via a guide assembly, a mounting plate 803 is connected to the strip plate 802 via an elastic assembly, a sealing strip 804 for sealing against the door curtain 103 is fixed to one side of the mounting plate 803, and a transmission assembly for transmitting the strip plate 802 is provided on the transmission plate 401;

[0035] It should be noted here that: when the rapid door needs to be closed, the transmission component is used to make the strip plate 802, which is subjected to force, move toward the outside of the mounting groove 801. During the movement, the sealing strip 804 on one side of the mounting plate 803 is abutted against the outside of the door curtain 103 through the connection of the elastic component. Through the abutment between the sealing strip 804 and the door curtain 103, the closed door curtain 103 is sealed in the form of a strip to ensure the sealing of the rapid door after closing.

[0036] Preferably, the transmission assembly includes a transmission pin 1101 fixed on the strip plate 802, and two sets of push plates 1102 are fixed on one side of the transmission plate 401. The two sets of push plates 1102 are provided with inclined surfaces 1103 for resisting and transmitting with the transmission pins 1101 on the two sets of strip plates 802;

[0037] It should be noted here that: when the rapid door needs to be closed, the strip pressure plate 3 is driven to move toward the bottom of the rapid door frame 101 and resist each other through transmission. During the movement of the strip pressure plate 3, the inclined surfaces 1103 of the two groups of push plates 1102 on the transmission plate 401 are respectively resisted against the transmission pins 1101 on the two groups of strip plates 802. During the resisting process, the strip plates 802 are subjected to force and move through transmission.

[0038] Preferably, the guide assembly includes a plurality of groups of first sleeves 1001 fixed inside the mounting groove 801, each group of first sleeves 1001 is slidably connected with a first slide bar 1002, and one end of the first slide bar 1002 is fixed to the strip plate 802;

[0039] It should be noted here that: the movement of the strip plate 802 after being subjected to force is guided by multiple sets of first sleeves 1001 and first sliding rods 1002 .

[0040] Preferably, the elastic component includes a plurality of groups of second sleeves 901 fixed on the strip plate 802, the second sleeves 901 are slidably connected with a second slide bar 902, one end of the second slide bar 902 is fixed to the mounting plate 803, and a spring 903 is sleeved on the outer side of the second sleeve 901, and the two ends of the spring 903 are respectively set against the mounting plate 803 and the strip plate 802;

[0041] It should be noted here that: after the sealing strip 804 on the mounting plate 803 abuts against the outer side of the door curtain 103, as the strip plate 802 continues to move, the strip plate 802 is forced to shrink toward the mounting plate 803. During the shrinking movement, each group of second sliding rods 902 is pushed to slide on each group of second sleeves 901 respectively, and the spring 903 is deformed under force to generate elastic force. Through the elastic force of the spring 903, the sealing strip 804 on the mounting plate 803 is pushed to maintain a close contact with the door curtain 103, thereby further improving the sealing effect of the fast door.

[0042] Preferably, the winding assembly includes an installation box 201 which is connected and fixed to the upper end of the fast door frame 101, the installation box 201 is rotatably connected with a winding shaft 202, the door curtain 103 is wound on the winding shaft 202, a baffle 203 is fixed on the winding shaft 202, a torsion spring 204 is sleeved on the outer side of the winding shaft 202, and the two ends of the torsion spring 204 are respectively connected to the baffle 203 and the inner wall of the installation box 201, and the interior of the installation box 201 is provided with a supporting assembly for supporting the door curtain 103 during the transmission process and a cleaning assembly for cleaning the surface of the door curtain 103 during the transmission process;

[0043] It should be noted here that: during the lifting and lowering movement of the transmission plate 401, the strip pressure plate 3 is driven to move synchronously. During the movement of the strip pressure plate 3, the door curtain 103 is pulled out or rolled up from the winding shaft 202 through the connection between the strip pressure plate 3 and the end of the door curtain 103, thereby realizing the opening and closing of the fast door.

[0044] Preferably, the support assembly includes a mounting shaft 501 rotatably connected to the mounting box 201, and a support roller 502 for abutting against the inner side of the door curtain 103 is fixed to the mounting shaft 501;

[0045] It should be noted here that: in the process of pulling out or rolling up the door curtain 103 from the winding shaft 202, the elastic component of the torsion spring 204 and the connection between the baffle 203 generate torque on the winding shaft 202, and through the torque and the supporting effect of the support roller 502 on the support component on the door curtain 103, the door curtain 103 is always in a taut state during the lifting process, which further facilitates the stable lifting operation of the door curtain 103 on the fast door.

[0046] Preferably, the cleaning assembly includes an operating shaft 601 rotatably connected to the inside of the installation box 201, a cleaning brush 602 for cleaning the surface of the door curtain 103 is fixed on the operating shaft 601, and two groups of cleaning brushes 602 are respectively set against the two sides of the door curtain 103, and the operating shaft 601 is connected and driven with the installation shaft 501 through a linkage assembly;

[0047] It should be noted here that: in the process of supporting the door curtain 103 by the support roller 502, the operating shaft 601 is driven to rotate through the connection transmission of the transmission component. In the process of rotation of the operating shaft 601, the cleaning brush 602 is driven to rotate. Through the rotation of the cleaning brush 602 and the transmission of the door curtain 103, different positions of the door curtain 103 during the transmission process are cleaned. By cleaning the door curtain 103, the cleanliness of the surface of the door curtain 103 is ensured, which further facilitates the subsequent efficient sealing operation of the door curtain 103.

[0048] Preferably, the linkage assembly includes pulleys 701 fixed on the mounting shaft 501 and the operating shaft 601, and the two sets of pulleys 701 are connected and driven by a belt 702;

[0049] It should be noted here that: in the process of supporting the door curtain 103 by the support roller 502, the support roller 502 and the installation shaft 501 are driven to rotate through the transmission of the door curtain 103 and the friction between the door curtain 103 and the support roller 502. In the process of rotation of the installation shaft 501, the operating shaft 601 is driven to rotate through the connection transmission between the belt 702 and the two sets of pulleys 701.

[0050] In this scheme: the rubber strip sealed fast door track includes the following steps:

[0051] When the rapid door is in use, the threaded rod 403 is driven to rotate by the driving motor 404. During the rotation of the threaded rod 403, the transmission plate 401 is driven to move by the mutual meshing transmission between the threaded rod 403 and the threaded sleeve 402. During the force movement of the transmission plate 401, the sliding guide action of the multiple groups of guide rods 405 causes the transmission plate 401 to move up and down on the rapid door frame 101 after being subjected to force. During the lifting and lowering of the transmission plate 401, the strip pressure plate 3 is driven to move synchronously. During the movement of the strip pressure plate 3, the strip pressure plate 3 is connected to the end of the door curtain 103 to pull out or reel in the door curtain 103 from the reel shaft 202, thereby realizing the opening and closing of the rapid door.

[0052] In the process of pulling out or reeling the door curtain 103 from the reel 202, the elastic component of the torsion spring 204 and the connection of the baffle 203 generate a torsion force on the reel 202. The torsion force and the support of the support roller 502 on the support assembly to the door curtain 103 keep the door curtain 103 in a taut state during the lifting process, which further facilitates the stable lifting and lowering operation of the door curtain 103 on the fast door. In the process of supporting the door curtain 103 by the support roller 502, the transmission of the door curtain 103 and the friction between the door curtain 103 and the support roller 502 are used. The supporting roller 502 and the installation shaft 501 are driven to rotate. During the rotation of the installation shaft 501, the connection transmission between the belt 702 and the two sets of pulleys 701 drives the operating shaft 601 to rotate. During the rotation of the operating shaft 601, the cleaning brush 602 is driven to rotate. Through the rotation of the cleaning brush 602 and the transmission of the door curtain 103, different positions of the door curtain 103 during the transmission process are cleaned. By cleaning the door curtain 103, the cleanliness of the surface of the door curtain 103 is ensured, which further facilitates the subsequent efficient sealing operation of the door curtain 103.

[0053] During the lifting and lowering of the door curtain 103, the sealing strip 804 on the mounting plate 803 does not contact the door curtain 103, and does not generate resistance to the lifting and lowering movement of the door curtain 103, further facilitating the stable lifting and lowering operation of the door curtain 103. When the rapid door needs to be closed, the strip pressure plate 3 is driven to move toward the bottom of the rapid door frame 101 and abut against each other through transmission. During the movement of the strip pressure plate 3, the inclined surfaces 1103 of the two groups of push plates 1102 on the transmission plate 401 are respectively abutted against the transmission pins 1101 on the two groups of strip plates 802. During the abutment, the strip plates 802 are forced to move through transmission. During the force applied to the strip plates 802, the sliding guiding effect of each group of first sleeves 1001 and the first sliding rods 1002 on the strip plates 802 causes the forced strip plates 802 to move toward the outer sides of the mounting grooves 801. During the movement, the sealing strip 804 on one side of the mounting plate 803 is abutted against the outer side of the door curtain 103 through the connection action of the elastic component. The closed door curtain 103 is sealed in the form of a strip through the abutment action of the sealing strip 804 and the door curtain 103, thereby ensuring the sealing of the fast door after closing. After the sealing strip 804 on the mounting plate 803 abuts against the outer side of the door curtain 103, as the strip plate 802 continues to move, the strip plate 802 is forced to contract toward the mounting plate 803. During the contraction movement, each group of second sliding rods 902 is pushed to slide on each group of second sleeves 901 respectively, and the spring 903 is deformed by force to generate elastic force. Through the elastic force of the spring 903, the sealing strip 804 on the mounting plate 803 is pushed to maintain a close contact and abutment state with the door curtain 103, thereby further improving the sealing effect of the fast door.
