Description

Technical Field

[0001] The present invention belongs to the field of processing of laminated thermal insulation curtain products, and specifically relates to a system for manufacturing laminated curtain products and a processing technology for laminated curtain products. Background Art

[0002] Most of the existing thermal insulation curtains adopt a laminated structure, that is, they include an inner layer, a core cotton layer and an outer layer from the inside to the outside, and the core cotton layer inside is used to ensure the effects of heat preservation, heat insulation and sound insulation. However, most of the edges of the existing thermal insulation curtain structures are protected by hemming the edge cloth through a sewing process. However, since the edge cloth cannot be removed after sewing, and since the thermal insulation curtain needs to be opened and closed frequently and the operation position is basically maintained at the edge cloth on the opening and closing side, the edge cloth at this place is extremely prone to stains, which is likely to cause cross-contamination when people pass through. The existing thermal insulation curtains need to be removed as a whole for all cleaning operations during cleaning, and the cleaning and replacement are difficult and the labor intensity is high, resulting in a poor user experience. Summary of the Invention

[0036] The air flow channel is communicated with the heating chamber through a one-way diaphragm.

[0037] The curtain processing technology adopts the curtain making system described above, including:

[0038] Step 1, raw material blank integration

[0039] The core cotton layer release roller, the inner layer release roller and the outer layer release roller release the core cotton layer, the inner layer and the outer layer synchronously and at the same speed, and then they are integrated into a three-layer laminated raw material blank by an integrating roller;

[0040] Step 2, curtain body forming

[0041] The raw material blank passes through the rear lower roller group, the upper rear tensioning wheel group, the upper front tensioning wheel group and the front lower roller group in sequence. Between the upper rear tensioning wheel group and the upper front tensioning wheel group, the upper embossing plate and the lower embossing plate approach each other, and the hot forming for combing the texture is completed through the embossing structure to obtain a curtain body blank;

[0042] Step 3, cutting

[0043] It is conveyed by a conveying roller and cut by a cutting piece to obtain a curtain body one and a curtain body two with designed dimensions;

[0044] Step 4, bottom head processing

[0045] The bottom edge is folded over the bottom of the curtain body by a bottom edge wrapper, and at the same time, the bottom edge is sewn to the bottom of the curtain body by a sewing piece one. A counterweight is installed inside the bottom edge while wrapping the bottom edge;

[0046] Step 5, side edge processing;

[0047] The rough surface structure is conveyed on the upper and lower sides of the side edge of the curtain body by a conveying structure one, and the side edge processing is completed through hot forming by a hot bonding roller;

[0048] Step 6, door head processing

[0049] The top edge is folded over the tops of the curtain body one and the curtain body two by a top edge wrapper. At this time, the tops of the curtain body one and the curtain body two are flush;

[0050] Step 7, Installation of the sealing structure

[0051] The edging strip is cut to a fixed length according to the length of the paired curtain body. The hook surface structure of the edging strip is bonded to the fleece surface structure of the curtain body, and the magnetic part is assembled inside the edging strip. The edging strips after the assembly of the first curtain body and the second curtain body are distributed front and back;

[0052] Step 8, Installation of the horizontal door head

[0053] Hook surface layers are installed on the inner and outer surface layers at the top of the first curtain body and the second curtain body. The fleece surface layer of the horizontal door head is bonded to the hook surface layer to obtain the door curtain product.

[0054] Compared with the prior art, the present invention has the following beneficial effects:

[0055] Improve the structure of the layered thermal insulation door curtain product:

[0056] 1) Fleece surface structures are provided on the sides of the first curtain body and the second curtain body. Hook surface stickers can be installed on the door frame. The hook surface stickers and the fleece surface structures are bonded to complete the installation of the thermal insulation door curtain. There is no problem of front and back installation, making it easier for users to install. At the same time, due to the frequent opening and closing of the magnetic part of the traditional thermal insulation curtain, the edging strip at this place is extremely easy to be polluted. If it needs to be cleaned, the entire curtain body needs to be removed for all cleaning operations, and the cleaning is difficult; while in this application, the edging strip at this place is independently set and bonded by the hook surface and the fleece surface. On the one hand, it can effectively fix the magnetic part, and on the other hand, it is convenient to carry out targeted cleaning operations on the edging strip at this place.

[0057] 2) The magnetic part in this case adopts a magnetic design with front-to-back attraction and front-to-back selective opening. When closed, the magnetic block of the opening part will adsorb and connect the connecting body, making the elastic body in a stretched state. At the same time, the connecting body will move along the guide groove body and compress the elastic part, and finally be restricted at the constraint arc groove, realizing the locking and fixing after magnetic attraction and improving the wind resistance performance; when opening, the connecting body is driven back to the end of the guide groove body by magnetic attraction through the movement of the opening part. After the opening part moves to the end position, the connecting body enters the guide groove body in the reverse direction under the action of the elastic reset of the elastic body and finally separates from the connecting groove, realizing magnetic locking. At this time, only the adsorption force of the magnetic block needs to be overcome to open the sealing structure. Two groups of magnetic blocks are arranged on both sides of the connecting groove to make the position of the wind resistance part correspond to the connecting groove when closed.

[0058] 3) In this case, hook surface layers and a horizontal door head are also provided on the inner and outer sides at the top of the first curtain body and the second curtain body. The fleece surface layer of the horizontal door head is bonded to the hook surface layer to conduct targeted thermal insulation design for the top of the curtain body. Since the edging strip of the sealing structure adopts a separate bonding design, there is a problem of heat loss between the edging strip and the door head. By enhancing the thermal insulation design of this structure, this problem is solved.

[0059] Improve the structure of the laminated thermal insulation curtain product:

[0060] 1) Using the intermittent planar embossing forming operation method, emboss the core cotton layer, inner surface layer and outer surface layer to obtain the curtain blank. When embossing, use the embossing plates to approach each other to complete the embossing operation of the embossing structure. The embossing structure is regularly patterned with hot melt columns, and there are gaps reserved between adjacent hot melt columns. Using this gap can facilitate the entry of hot air flow after heat sealing to fluff the core layer cotton in the combed pattern.

[0061] 2) After heat sealing, use the side opening pieces on the side to open both sides of the surface layer under the action of the motor. After opening, the pump body is turned on to lead the hot air flow out of the heating chamber through the air flow channel and into the core layer cotton through the air inlet and outlet. The air flow discharged outside the heating chamber is greater than the air flow entering through the air holes, making the inside in a negative pressure state. The negative pressure state will adsorb the surface layer of the area surrounded by the hot melt columns by the capsule body under the action of capillary holes. When adsorbed, the capsule body will also be deformed into the shaping groove to complete the fluffing treatment of this area. While fluffing, the temperature of the hot melt column is slowly cooled by the entering air, releasing the stress after heat sealing and preventing wrinkling in this part.

[0092] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0093] Example 1

[0094] As Figures 1 to 7 shown, a curtain structure includes:

[0095] A first curtain body 10 and a second curtain body 20. Both the first curtain body 10 and the second curtain body 20 include an inner surface layer 11, an outer surface layer 12, and a core cotton layer 13 distributed therebetween. Fluffy surface structures 14 are provided on the sides of the first curtain body 10 and the second curtain body 20, and two sets of the fluffy surface structures 14 on the curtain body are respectively distributed on the inner surface layer 11 and the outer surface layer 12 of the curtain body;

[0096] A sealing structure 30. The sealing structure 30 includes two edge strips 31. On one side of each edge strip 31, two symmetrically distributed hook surface structures 32 and magnetic attraction members 33 distributed in the middle of the hook surface structures 32 are provided. A plurality of magnetic attraction members 33 are equally spaced along the length direction of the edge strip 31. The two hook surface structures 32 are respectively adhered to the fluffy surface structures 14 on the inner surface layer 11 and the outer surface layer 12 of the curtain body.

[0097] In the embodiment, a hook surface sticker is installed on the door frame, and the fluffy surface structure 14 at the edge of the curtain body is bonded to the hook surface sticker to complete the fixation of the curtain structure, so that the problem of reverse installation will not occur. At the same time, the edge strips 31 are used to bond the opening and closing sides of the first curtain body 10 and the second curtain body 20 through the hook surface and the fluffy surface, and the disassembly and assembly operations of the edge strips 31 can be completed. After the edge strips 31 are contaminated, they can be separately removed for cleaning and are easy to reassemble. When the sealing structure 30 is closed, the two edge strips 31 are closely contacted by the magnetic attraction of the magnetic attraction members 33 to complete the closing, thereby ensuring the heat preservation and heat insulation effect.

[0098] Example 2

[0099] In Example 1, since the existing heat preservation curtain products of layered products adopt the magnetic attraction scheme of mutual attraction, when encountering strong wind weather, the air flow impacts the curtain, which is likely to cause the magnetic attraction structure to be accidentally opened, especially in the bottom area. In view of this, the inventor makes the following improvements:

[0100] As Figures 1 to 12 shown, the magnetic attraction member 33 includes an upper magnetic attraction structure 331, a lower magnetic attraction structure 333, and a middle magnetic attraction structure 332 distributed between the upper magnetic attraction structure 331 and the lower magnetic attraction structure 333. The middle magnetic attraction structure 332 includes a middle fixing block 3321. On the opposite sides of the middle fixing blocks 3321 of the two sets of magnetic attraction members 33, transverse sliding grooves 3322 are provided, and a transverse opening member 3323 is slidably fitted in the transverse sliding grooves 3322.

[0101] The upper magnetic attraction structure 331 and the lower magnetic attraction structure 333 both include a plurality of side fixing blocks 3311 arranged along the length direction of the edge strip 31. On the side of the side fixing blocks 3311 of the two groups of magnetic attraction members 33 facing away from each other, there are vertical sliding grooves 3312. A vertical opening member 3313 is slidably fitted in the vertical sliding grooves 3312. All the vertical opening members 3313 of the upper magnetic attraction structure 331 and all the vertical opening members 3313 of the lower magnetic attraction structure 333 are respectively connected by a separate connecting rope 3314 and a horizontal opening member 3323, and spring members 3315 for connecting the corresponding vertical opening members 3313 are installed in the vertical sliding grooves 3312 at the topmost side and the lowermost side.

[0102] Among them, magnetic attraction blocks 334 are embedded on the sides of the horizontal opening member 3323 and the vertical opening member 3313 facing away from the fixing blocks. The magnetic attraction blocks 334 are used for adsorbing the connecting body 3385.

[0103] On the opposite sides of the two middle fixing blocks 3321 corresponding in position in the two groups of magnetic attraction members 33 and on the opposite sides of the two side fixing blocks 3311 corresponding in position in the two groups of magnetic attraction members 33, there are magnetic blocks 335 and connecting grooves 336. A guide groove body 337 and a wind-resistant member 338 detachably connected inside are arranged on the side of the connecting groove 336. The guide groove body 337 is distributed in a spiral structure, and circumferentially distributed constraint arc grooves 339 are arranged on one side close to the root of the connecting groove 336. The edge strip is bonded to the fixing block and is also located at the positions of the grooves. The edge strip is also bonded in the grooves without affecting the structural shapes of the grooves. The edge strip can also expose the grooves by making cuts at the positions of the grooves, either way is acceptable.

[0104] The wind-resistant member 338 includes a main body 3381 and an extension body 3383. Two moving plates 3382 are installed inside the main body 3381 and an elastic body is connected between the two moving plates 3382. An elastic member 3384 and a rotatable connecting body 3385 are installed at the end of the extension body 3383. The two ends of the elastic member 3384 are respectively connected to the extension body 3383 and the connecting body 3385.

[0105] Driven by the movement of the horizontal opening member 3323 and the vertical opening member 3313, the connecting body 3385 rotates by a certain angle.

[0106] Among them, the opening members, the wind-resistant members, and the fixing blocks are all made of PVC material.

[0107] When in use, when opening from the outside, the transverse opening member 3323 inside the edge strip 31 of the curtain body 10 is pushed to the right. Due to the existence of the bottom counterweight, only the acting force of the spring member 3315 at the bottom needs to be overcome, and the vertical opening member 3313 can be moved closer to the transverse opening member 3323. At the same time, the edge strip 31 hardly deforms in the length direction. Due to the adsorption of the magnetic attraction block 334 on the connecting body 3385, the connecting body 3385 moves along with the movement of the magnetic attraction block 334, squeezes the elastic member 3384 and rotates from inside the constraint arc groove 339 to the root of the guide groove body 337. When the opening member moves to the end position, the magnetic attraction force is less than the elastic restoring force of the elastic body, and the connecting body 3385 will automatically move in the reverse direction along the guide groove body 337 and be removed. The wind-resistant member 338 is removed from the connecting groove 336 of the curtain body 10. At this time, only the magnetic force of the magnetic block 335 for attraction needs to be overcome to open the sealing structure 30. After the person passes through, the magnetic block 335 will attract each other. While attracting each other, the connecting body 3385 can be automatically inserted into the connecting groove 336. Under the action of the adsorption force of the magnetic attraction block 334, the connecting body 3385 moves along the guide groove body 337. While moving, the elastic body will be stretched, the connecting body 3385 will rotate by a certain angle and at the same time compress the elastic member 3384. When the connecting body 3385 enters the constraint arc groove 339, it will be constrained in the constraint arc groove 339 under the action of the magnetic attraction angle and the elastic member 3384; when opening from the inside, the action is the same. In actual use, the position where the transverse opening member 3323 is located can be marked.

[0108] As Figure 13 shown, the three-piece curtain body method is adopted. The curtain body 20 is located inside the curtain body 10. Of course, the magnetic blocks 335 on the same magnetic attraction member 33 can be selected as upper, middle and lower continuous soft magnetic strips.

[0109] Embodiment 3

[0110] In Embodiment 1, as Figure 1 、 Figure 4 、 Figure 5 shown, the curtain structure further includes hook surface layers and a horizontal door head 3386 arranged on the inner and outer sides of the tops of the curtain body 10 and the curtain body 20. A hair surface layer adhesively bonded to the hook surface layer is arranged on one side of the horizontal door head 3386 opposite to the hook surface layer.

[0111] The hair surface layer of the horizontal door head 3386 and the hook surface layer are adhesively bonded to conduct targeted heat preservation design on the top of the curtain body. Since the edge strip 31 of the sealing structure 30 adopts a separate adhesive bonding design, there is a problem of heat loss between the edge strip and the door head. By enhancing the heat preservation design of this structure, this problem is solved.

[0120] In this embodiment, the core cotton layer release roller 101, the inner surface layer release roller 102 and the outer layer release roller 103 release the core cotton layer 13, the inner surface layer 11 and the outer surface layer 12 synchronously and at the same speed, and then integrate them into a raw material blank through the integration roller 104, the tensioning part 210 tensions the raw material blank, and the three layers of raw materials are fused through the embossing part 220 to form a curtain body blank with combing patterns, which is transported to the cutting station by the conveying roller 301, and the blank cutting operation of the curtain body 10 and the curtain body 20 is completed according to the design size requirements, and the blanks of the curtain body 10 and the curtain body 20 enter the bottom processing station, and the bottom hemming strip is folded and hemmed at the bottom by the bottom hemming device 401, and the counterweight is loaded into the bottom hemming strip when it is folded, and the bottom hemming strip is sewed to the bottom of the curtain body through the sewing piece 1 402. The bottom hemming process is carried out longitudinally, and after sewing, the curtain body is longitudinally transported to the heat sealing station through the longitudinal conveying structure 403, and the curtain body is transversely transported at the heat sealing station. During the conveying process, the conveying structure 501 transversely transports the rough surface structure 14, and the conveying structure 501 is provided with two groups of upper and lower groups, which are respectively located on the upper and lower sides of the curtain body, and then heat-sealed on the two side edges of the curtain body through the heat sealing roller 502. The curtain body 10 and the curtain body 20 are processed at the door head station, and the top hemming strip is folded by the top hemming device 601 and sewn at the top by the sewing piece 2 602. Finally, the hemming strip 31 is cut according to the length of the curtain body 10 and the curtain body 20, and is installed at the rough surface structure 14 on the opening and closing side of the curtain body 10 and the curtain body 20 using the hook surface structure 32.

[0121] Example 5

[0122] In Example 4, the existing layered thermal insulation curtain adopts a sewing process to prevent the design of cotton leakage, which causes surface wrinkles. At the same time, due to the existence of the sewing opening and sewing line, frequent force is applied to complete the opening and closing of the thermal insulation curtain, which easily causes the line opening to increase and leads to poor thermal insulation effect. The traditional way to solve the deviation is to use rolling, but the subsequent re-expansion of the core cotton layer is ignored, which will also cause a certain amount of expansion, thereby causing wrinkles. The inventor has made the following improvements:

[0123] like Figures 15 to 23 As shown, the tensioning part 210 includes a front lower roller group 211, a rear lower roller group 212, an upper front tensioning wheel group 213 and an upper rear tensioning wheel group 214, and the front lower roller group 211 and the rear lower roller group 212 are distributed below between the upper front tensioning wheel group 213 and the upper rear tensioning wheel group 214;

[0124] The embossed part 220 includes an upper embossed plate 221 and a lower embossed plate 222. A molding groove 223 is provided in the middle of the opposite side of the upper embossed plate 221 and the lower embossed plate 222. An embossed structure 224 and an adsorption structure 225 are installed in the molding groove 223. The embossed structure 224 hot-melts the raw material blank into one, and the adsorption structure 225 makes the raw material blank fluffy except for the embossed structure 224.

[0125] Both sides of the forming groove 223 along the direction perpendicular to the movement direction of the raw material blank are provided with air inlet and outlet openings 226;

[0126] The embossing structure 224 includes a forming plate 227 installed inside the forming groove 223. A number of through holes are evenly distributed on the forming plate 227, and hot melt columns 229 are installed in the through holes. An electric heating structure 228 is independently arranged inside the forming groove 223. The electric heating structure 228 provides a fusing temperature for the hot melt columns 229. A heating chamber is surrounded by the side of the forming plate 227 facing away and the forming groove 223;

[0127] The adsorption structure 225 includes a shaping groove 2252 distributed on the opposite sides of the forming plate 227 and a bladder 2251 built in at the notch of the shaping groove 2252 and flush with the plate surface. Capillary holes are evenly distributed on the bladder 2251.

[0128] Two symmetrically distributed side slots 230 are provided on the upper embossing plate 221 and the lower embossing plate 222. The two side slots 230 are distributed on both sides of the forming groove 223 along the direction perpendicular to the conveying direction of the raw material blank;

[0129] A motor 232 is embedded in the upper embossing plate 221 and the lower embossing plate 222. A rotating rod 231 is installed at the output end of the motor 232. A side opening piece 233 is fixed on the rotating rod 231. The side opening piece 233 is arranged in the side slot 230;

[0130] Air flow holes 235 are provided on the upper embossing plate 221 and the lower embossing plate 222 on the side facing away from the forming groove 223, and a pump body 234 is independently embedded inside the embossing plate. The air inlet and outlet openings 226 and the air flow holes 235 are communicated through an air flow channel 236 and the pump body 234. A directional air flow is formed by the pump body 234 from the air flow holes 235 entering through the air flow channel 236 and the air inlet and outlet openings 226.

[0131] The side opening piece 233 includes a side opening cam disc 2331 and a spiral piece 2332 spirally distributed on the rotating rod 231. One end of the spiral piece 2332 away from the motor 232 is connected to the side opening cam disc 2331. According to the spiral piece 2332, the surface layer part is opened to both sides, which is beneficial for the air inlet and outlet openings 226 to provide hot air flow to the area not covered by the hot melt columns 229.

[0132] The shaping groove 2252 is communicated with the heating chamber through a one-way diaphragm, and the air flow channel 236 is communicated with the heating chamber through a one-way diaphragm, which is beneficial for the formation of a directional air flow and the internal negative pressure state of the heating chamber when necessary.

[0133] On the opposite sides of the upper embossing plate 221 and the lower embossing plate 222, air cylinders are provided for the two to approach or move away from each other. During the heat sealing of the raw material blank by the upper embossing plate 221 and the lower embossing plate 222, the electric heating structure 228 will heat the hot melt column 229 to a set temperature, and heat and fuse the raw material blank at the corresponding position of the hot melt column 229 into a whole. After fusion, the electric heating structure 228 stops the heating operation. At the same time, the motor 232 drives the side opening piece 233 to open the surface layer part of the side of the curtain body to both sides through the rotating rod 231. The pump body 234 is turned on to transport the heated gas in the heating chamber to the air inlet and outlet 226 through the air flow channel 236. Since there is a certain gap reserved between adjacent hot melt columns 229, the structure inside the curtain body can supply hot air to enter. The hot air enters the area not covered by the embossing structure 224 for hot air blowing treatment. At the same time, since the air flow entering through the air flow holes 235 is less than the air flow extracted by the pump body 234 outside, the air pressure in the heating chamber is lower than the external air pressure, and the heating chamber is in a negative pressure state. The bladder 2251 will adsorb on the surface layer by using capillary holes. At the same time, due to the decrease in air pressure in the shaping groove 2252, the bladder 2251 is attached to the inner wall of the shaping groove 2252, and the whole surface layer is extended outward away from the core cotton layer 13. Since the hot air flow inside the heating chamber is discharged laterally between the two surface layers, the hot melt column 229 is slowly cooled by the air entering from the outside, and at the same time, the stress of the heat-sealed part is gradually released, and no wrinkling problem will occur.
