Description

Technical Field

[0001] This utility model belongs to the field of insulated door curtains, specifically relating to a splicing multifunctional insulated door curtain. Background Technology

[0002] During the processing of composite flooring, due to specific process requirements, factors such as UV curing lamps, machine heating, odors emitted from coatings during production, and the emission of harmful gases during production need to be controlled. Therefore, it is necessary to seal the entire coating area of ​​the coating workshop and carry out safe treatment of waste gas before emission.

[0003] Current technologies typically use partitions to seal the coating area, but complete sealing is not possible in the conveyor belt areas where products are fed and discharged. The main process involves sending the composite boards to be processed into the coating workshop via a conveyor belt for specific processing, and then transporting them automatically via a conveyor belt after completion. This requires sealing the dynamically open sections while maintaining continuous production without stopping the machine.

[0004] Therefore, a specially designed insulated door curtain is needed that can allow products such as panels to pass through without obstruction, while preventing the exhaust of hot air and harmful gases. Utility Model Content

[0005] The purpose of this invention is to address the lack of a sealing method for dynamically connected openings in continuous production environments in existing technologies. Therefore, this invention provides a modular, multi-functional insulated door curtain.

[0006] To achieve the above objectives, the present invention proposes the following technical solution: A splicing multi-functional insulated door curtain includes a first guide rail and several first curtain components; The first guide rail is provided with a plurality of first slots, which are arranged coaxially along the extension direction of the first guide rail at fixed intervals, and the first guide rail is provided with first slots at both opposite ends of the extension direction. The first curtain assembly includes a first mounting component and a first curtain slat. The upper end of the first mounting component is provided with a first buckle, and the first curtain slat is fixedly mounted on the lower end of the first mounting component. The first buckle cooperates with the first slot, so that the first buckle is adapted to be installed inside the first slot, thereby allowing the first curtain assembly to be installed on the first guide rail, and the first curtain panels of adjacent first curtain assemblies at least partially overlap, with the gap in the overlapping area forming a primary airflow channel. The side of the first curtain slat closest to the heat source is defined as the inner side, and the side furthest from the heat source is defined as the outer side. Hot air flows from the inner side of the first curtain slat to the outer side of the first curtain slat through the primary airflow channel.

[0007] Furthermore, the first mounting component also includes a first connecting portion, and the first buckle is disposed at the upper end of the first connecting portion; The first buckle, the first connecting part, and the first curtain slat are all provided with a plurality of mounting holes. The first buckle is fixed to the upper end of the first connecting part through the mounting holes, and at least a portion of the upper end of the first curtain slat is fixed to the lower end of the first connecting part through the mounting holes.

[0008] Furthermore, the first card slot includes a first card slot opening and a first sliding groove, wherein the first sliding groove is disposed below the first card slot opening and communicates with the gap where the first card slot opening is located; The first slot opening extends in a direction parallel to the first guide rail extending in a direction, and the first slide groove extends in a direction perpendicular to the first slot opening extending in a direction. The extension direction of the first card slot opening is defined as the length direction, and the length of the first card slot opening is greater than the length of the first slide groove. The first buckle includes a first buckle head and a first buckle neck, wherein the first buckle head is disposed above the first buckle neck and connected to the first buckle neck; The first buckle head extends in a direction parallel to the first buckle slot opening, and the first buckle neck extends in a direction perpendicular to the first buckle head. The length of the first buckle head is greater than the length of the first buckle neck; The length of the first slot opening is greater than or equal to the length of the first buckle head, the length of the first buckle head is greater than the length of the first slide groove, and the length of the first buckle neck is less than the length of the first slide groove.

[0009] Furthermore, the first slat includes several insulating layers, and the insulating layers include at least a first insulating layer, a second insulating layer, and a third insulating layer; The first isolation layer, the second isolation layer, and the third isolation layer are stacked sequentially and arranged in parallel from the front end to the rear end of the first curtain slat. The first isolation layer, the second isolation layer, and the third isolation layer are connected sequentially by being fixed to the upper end of the first connecting part; The first isolation layer, the second isolation layer, and the third isolation layer all have at least some areas that overlap with each other.

[0010] Furthermore, the first isolation layer, the second isolation layer, and the third isolation layer of the first curtain slat each include an upper section and a lower section, and the lower end of the upper section is fixedly connected to the upper end of the lower section; The direction in which the first curtain slat naturally falls is defined as the length direction, and the length of the upper section is greater than the length of the lower section; The upper section and the lower section are made of different materials.

[0011] Furthermore, the insulated door curtain also includes a second guide rail and a plurality of second curtain assemblies, wherein the second guide rail is disposed above the first guide rail; The second guide rail has the same structure as the first guide rail, including several second slots; The second curtain assembly has the same structure as the first curtain assembly, including a second mounting component and a second curtain slat; The second curtain assembly is disposed outside the first curtain assembly; After passing through the first slat, the hot air flows from the inside of the second slat to the outside of the second slat.

[0012] Furthermore, the position of the second slot corresponds to the fixed interval position of the first slot arranged below it, so that the second curtain and the first curtain are laterally offset from each other, so that the outer surface of the first curtain and the inner surface of the second curtain correspond to each other in the front and back overlapping area, and the gap in the front and back overlapping area forms a secondary airflow channel.

[0013] Furthermore, the second curtain slats of the adjacent second curtain assemblies at least partially overlap, and the gaps in the overlapping areas form a three-level airflow channel; After passing through the first slat, the airflow passes through the secondary airflow channel and then flows from the inside of the second slat to the outside of the second slat through the tertiary airflow channel.

[0014] Furthermore, the second card slot has the same structure as the first card slot, and the second card slot includes a second card slot opening and a second sliding groove; The upper end of the second mounting component is provided with a second buckle, the second buckle has the same structure as the first buckle, and the second buckle includes a second buckle head and a second buckle neck; The length of the second slot opening is greater than or equal to the length of the first slot opening; the length of the second buckle head is greater than or equal to the length of the first buckle head.

[0015] Furthermore, the length of the second slat is greater than the length of the first slat, the width of the second slat is greater than or equal to the width of the first slat, and the lower edges of the first slat and the second slat are flush when hanging down.

[0016] The beneficial effects of this utility model are: (1) By setting a slot and buckle structure, the curtain slat assembly is installed and fixed on the guide rail to prevent it from shifting or derailing due to the stress of conveyor belt transportation. At the same time, the splicing setting of multiple curtain slat assemblies installed on the same guide rail and the partial overlap of adjacent curtain slat assemblies greatly enhances the barrier effect of the door curtain. This avoids the obvious gap caused by the mechanical movement of adjacent curtain slats when the conveyor belt transports the board material, which would cause the lower edge of the curtain slat to move due to force, resulting in the loss of gas and heat in the workshop.

[0017] (2) This utility model sets up a multi-layer composite curtain structure by stacking multiple isolation layers as curtain slats. On the one hand, it addresses the problem of gaps caused by the movement of the lower edge of the curtain slats due to the force of the conveyor belt. The multi-layer composite curtain can effectively reduce the movement gaps and enhance the barrier effect of the curtain. On the other hand, the isolation layer materials can be set separately according to actual needs, so that they can meet the actual production isolation needs. It can prevent the exhaust of hot air and harmful gases, and also prevent heat loss, thus realizing the functional design of multi-functional barrier.

[0018] (3) This utility model sets the lower edge of the individual curtain slat isolation layer as a spliced ​​design of the lower section. The material of the lower section is selectively set for the board products that are transported to the upper transport. On the one hand, it avoids the lower edge of the curtain slat from scratching or damaging the surface of the board products that pass through the curtain, thus affecting the quality of the board products. On the other hand, it avoids the problem of large friction between the isolation layer material and the board surface, which leads to the stacking and jamming of the boards and affects the overall processing progress.

[0019] (4) Through the multi-level airflow channel design, the hot air and harmful gases in the workshop need to pass through multiple levels of gas channels in sequence when passing through the barrier curtain, which greatly enhances the barrier effect of the door curtain on gas and heat. In conjunction with the above design, it achieves the sealing of the dynamic through opening under the condition of continuous production without stopping the machine.

[0020] (5) It should be understood that all combinations of the foregoing concepts and the additional concepts described in more detail below can be considered as part of the utility model subject matter of this disclosure, provided that such concepts do not contradict each other.

[0026] See attached document Figure 1 As shown, this utility model provides a splicing multi-functional door curtain, including a first guide rail 1 and several first curtain components 3.

[0027] The first guide rail 1 is provided with a plurality of first slots 2. The plurality of first slots 2 are arranged coaxially along the extension direction of the first guide rail 1 at fixed intervals, and the first guide rail 1 is provided with first slots 2 at both ends opposite to each other in the extension direction, so as to ensure that the blocking area of ​​the door curtain meets the requirements.

[0028] Specifically, the fixed interval between the first card slots 2 is set to 20 mm, and the specific data can be adjusted according to actual needs.

[0029] The first slot 2 includes a first slot opening 21 and a first sliding groove 22. The first sliding groove 22 is located below the first slot opening 21 and communicates with the gap where the first slot opening 21 is located.

[0030] The first slot opening 21 extends in a direction parallel to the extension direction of the first guide rail 1, and the first slide groove 22 extends in a direction perpendicular to the extension direction of the first slot opening 21.

[0031] The extension direction of the first slot opening 21 is defined as the length direction, and the length of the first slot opening 21 is greater than the length of the first groove 22.

[0032] See attached document Figure 2 As shown, the first curtain assembly 3 includes a first mounting component and a first curtain slat 33. The upper end of the first mounting component is provided with a first buckle 31, and the first curtain slat 33 is installed and fixed at the lower end of the first mounting component.

[0033] Specifically, the first buckle 31 is integrally machined on the first mounting component, and the first curtain slab 33 is fixed to the lower end of the first mounting component by means including but not limited to welding, gluing, mechanical connection, etc.

[0034] In some optional embodiments, the first mounting component further includes a first connecting portion 32, and a first buckle 31 is disposed on the upper end of the first connecting portion 32. The first buckle 31, the first connecting portion 32, and the first curtain slat 33 are all provided with a plurality of mounting holes. The first buckle 31 is fixed to the upper end of the first connecting portion 32 through the mounting holes, and at least a portion of the upper end of the first curtain slat 33 is fixed to the lower end of the first connecting portion 32 through the mounting holes.

[0035] Specifically, the first curtain slat 33 and the first buckle 31 are fixed to the first connecting part 32 by bolts and nuts. The installation position of the first curtain slat 33 and the first buckle 31 can be adjusted by the position of the mounting holes on the first connecting part 32 to fit the usage requirements.

[0036] The first buckle 31 includes a first buckle head 311 and a first buckle neck 312. The first buckle head 311 is disposed above the first buckle neck 312 and connected to the first buckle neck 312.

[0037] The first buckle head 311 extends in a direction parallel to the extension direction of the first buckle slot opening 21, and the first buckle neck 312 extends in a direction perpendicular to the extension direction of the first buckle head 311.

[0038] The length of the head 311 of the first buckle is greater than the length of the neck 312 of the first buckle.

[0039] The length of the first slot opening 21 is greater than or equal to the length of the first buckle head 311, the length of the first buckle head 311 is greater than the length of the first slide groove 22, and the length of the first buckle neck 312 is less than the length of the first slide groove 22.

[0040] Specifically, both the first slot 2 and the first buckle 31 are T-shaped. The recessed part of the first slot 2 matches the protruding part of the first buckle 31. During installation, the head 311 of the first buckle can be inserted into the opening 21 of the first slot until the neck 312 of the first buckle enters the opening 21 of the first slot. Then, the neck 312 of the first buckle is moved downward along the neck until the end. During this process, because the length of the opening 21 of the first slot is greater than the length of the first slide 22, it can be ensured that the head 311 of the first buckle will not fall out of the first slot 2 during the movement. Afterwards, because the length of the head 311 of the first buckle is greater than the length of the first slide 22, the first buckle 31 can be installed in the first slot 2 to prevent it from falling out.

[0041] Specifically, the length of the first slot opening 21 is 30 mm, the length of the first slide groove 22 is 15 mm, the length of the first buckle head 311 is 26 mm, and the length of the first buckle neck 312 is 10 mm. Specific data can be adjusted according to actual needs.

[0042] In summary, the first buckle 31 cooperates with the first slot 2, allowing the first buckle 31 to be installed inside the first slot 2, thereby allowing the first curtain assembly 3 to be installed on the first guide rail 1, and the first curtain slats 33 of the adjacent first curtain assemblies 3 at least partially overlap, with the gap in the overlapping area forming a primary airflow channel 51.

[0043] The width direction of the first slat 33 is parallel to the extension direction of the first guide rail 1.

[0044] Specifically, the width of the first slat 33 is 180mm, and the width of the aforementioned overlapping area is 20-25mm. The specific data will be adjusted according to actual needs.

[0045] Preferably, the width of the overlapping area is 10-15% of the width of the first slat 33.

[0046] Specifically, when the conveyor belt transports the sheet material, the mechanical movement causes the lower edge of the curtain to move under force, creating gaps between adjacent curtains. This makes it impossible to block the gas and heat in the workshop. Therefore, the adjacent first curtains 33 are partially overlapped, which greatly enhances the blocking effect and avoids the overlap area being too large, thus affecting the transport of the sheet material.

[0047] See attached document Figure 3 As shown, the first slat 33 includes several isolation layers, including at least a first isolation layer 331, a second isolation layer 332 and a third isolation layer 333.

[0048] The gas flow direction is defined as coming from the rear end of the first curtain slat 33 to the front end.

[0049] The first isolation layer 331, the second isolation layer 332, and the third isolation layer 333 are stacked sequentially and arranged in parallel from the front end to the rear end of the first slat 33. The first isolation layer 331, the second isolation layer 332, and the third isolation layer 333 are connected sequentially by being fixed to the upper end of the first connecting part 32. The first isolation layer 331, the second isolation layer 332, and the third isolation layer 333 all have at least a partial overlap with each other.

[0050] In some alternative embodiments, the first isolation layer 331, the second isolation layer 332, and the third isolation layer 333 are of the same size and are stacked sequentially to form a multi-layer composite curtain.

[0051] Specifically, the materials of the first isolation layer 331, the second isolation layer 332, and the third isolation layer 333 can be selected according to actual needs.

[0052] Preferably, the first isolation layer 331 is a windproof layer, made of PVC, used to block hot air and harmful gases blown out from the isolation workshop; the second isolation layer 332 is a heat insulation layer, made of non-woven fabric or foam material, used to block hot airflow from the isolation workshop and prevent heat loss from the workshop; the third isolation layer 333 is a windproof layer, made of PVC, used to further block hot air and harmful gases blown out from the isolation workshop and enhance the barrier effect of the curtain.

[0053] The material of each insulation layer can be selected and replaced according to actual needs.

[0054] In some alternative embodiments, the first isolation layer 331, the second isolation layer 332 and the third isolation layer 333 of the first curtain slat 33 each include an upper section 301 and a lower section 302, with the lower end of the upper section 301 fixedly connected to the upper end of the lower section 302; the upper section 301 and the lower section 302 are made of different materials.

[0055] The direction in which the first curtain slat 33 hangs naturally is defined as the length direction, and the length of the upper section 301 is greater than the length of the lower section 302.

[0056] Preferably, the length of the lower section 302 is 3-5% of the length of the first slat 33.

[0057] Specifically, the upper section 301 is made of the main material of the insulation layer, used for wind and heat insulation. Considering that the curtain is used to prevent the dissipation of gas and heat from the workshop, the lower edge of the curtain, located on the conveyor belt, can scrape the surface of the conveyed sheet products during conveyor belt operation, easily leading to surface damage, or problems such as sheet stacking and jamming, which adversely affects sheet processing. To solve this problem, the lower section 302 is made of a lightweight material, such as fiber, cotton, felt, or soft PVC. At the same time, to avoid affecting the heat insulation performance of the lower section 302, its length is limited.

[0058] In some alternative embodiments, the insulated door curtain also includes a second guide rail and several second curtain assemblies, the second guide rail being disposed above the first guide rail 1.

[0059] The structure of the second guide rail is the same as that of the first guide rail 1, and the component structure for installing the second curtain on the second guide rail is the same as described above. Figure 1 Appendix Figure 2 same.

[0060] The second guide rail is provided with a number of second slots, which are arranged coaxially along the extension direction of the second guide rail at fixed intervals, and the second guide rail is provided at both ends opposite to each other along the extension direction.

[0061] The second slot is positioned at a distance from the first slot 2 located below it, and is used to offset the position of the second slat from the position of the first slat 33, so as to avoid the second slat being completely overlapped with the first slat 33, which would affect the transportation of the board.

[0062] The second curtain assembly has the same structure as the first curtain slat assembly 3. The second curtain assembly includes a second mounting component and a second curtain slat. The upper end of the second mounting component is provided with a second buckle, and the second curtain slat is installed and fixed on the second mounting component.

[0063] The second buckle cooperates with the second slot, allowing the second buckle to be installed inside the second slot, thereby allowing the second curtain assembly to be installed on the second guide rail. Furthermore, the second curtain assembly is positioned in front of the first curtain assembly 3, which can further enhance the overall curtain barrier effect.

[0064] The second slot includes a second slot opening and a second sliding groove. The second sliding groove is located below the second slot opening and communicates with the gap where the second slot opening is located. The length of the second slot opening is greater than the length of the second sliding groove.

[0065] The second buckle includes a second buckle head and a second buckle neck. The second buckle head is located above the second buckle neck and connected to the second buckle neck. The length of the second buckle head is greater than the length of the second buckle neck.

[0066] The length of the second slot opening is greater than or equal to the length of the second buckle head, the length of the second buckle head is greater than the length of the second slide groove, and the length of the second buckle neck is less than the length of the second slide groove.

[0067] The length of the second slat is greater than the length of the first slat 33, and the lower edges of the first slat 33 and the second slat are flush when hanging down.

[0068] In some alternative embodiments, the length of the second slot opening is greater than or equal to the length of the first slot opening 21; the length of the second buckle head is greater than or equal to the length of the first buckle head 311; and the width of the second slat is greater than or equal to the width of the first slat 33.

[0069] Specifically, the width of the second slat is greater than that of the first slat 33, which can provide secondary obstruction to the airflow passing through the first slat 33, further enhancing the effect of blocking hot airflow and preventing heat loss.

[0070] The second slat also has an upper section and a lower section to ensure that the lower edge of the slat will not scratch the transported boards. In order to avoid affecting the transport of the boards, the second slat uses a single-layer isolation layer, and the material of the isolation layer can be selected and replaced according to actual needs.

[0071] The side of the first curtain slat 33 closest to the heat source is defined as the inner side, and the side furthest from the heat source is defined as the outer side.

[0072] The position of the second slot corresponds to the fixed interval of the first slot 2, so that the second curtain and the first curtain 33 are laterally offset from each other, so that the outer surface of the first curtain 33, which is adjacent in the inner and outer directions, corresponds to the inner surface of the second curtain in the front and back overlapping area, and the gap in the front and back overlapping area forms a secondary airflow channel 52.

[0073] In some alternative embodiments, the second curtain slats of adjacent second curtain assemblies at least partially overlap, and the gaps in the overlapping areas form a three-stage airflow channel 53.

[0074] When hot air and harmful gases that need to be blocked in the workshop pass through the first curtain 33, they are blocked and diverted by the primary airflow channel 51, flowing from the inside of the first curtain 33 to the outside of the first curtain 33. Then, they are further blocked and diverted by the secondary airflow channel 52, flowing from the outside of the first curtain 33 to the inside of the second curtain. Finally, they flow from the inside of the second curtain to the outside of the second curtain through the tertiary airflow channel 53.

[0075] In this process, multi-layered composite curtains significantly enhance the barrier effect against gas and heat, avoiding the problems of integral curtains being too heavy and affecting the transportation of the panels, as well as the problem of gas escaping from the gaps between adjacent curtains, resulting in the barrier effect not meeting expectations.

Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
