Description

Technical Field

[0001] The invention relates to the field of thermal insulation curtain processing equipment, and in particular to a thermal insulation curtain processing system. Background Art

[0002] Thermal insulation curtains are usually made of PVC, fiberglass, polyester, etc. These materials have good thermal insulation properties and can effectively reduce the accumulation of indoor heat, thereby reducing indoor temperature and energy consumption. In addition, thermal insulation curtains can also maintain indoor temperature in winter and reduce heating consumption.

[0003] Among them, PVC thermal insulation curtains are generally used on door frames in supermarkets, cold storage and other places that require insulation. In order to facilitate entry and exit during the processing and production of this type of thermal insulation curtain, multiple pieces are assembled to cover the entry and exit channels. Since multiple pieces are assembled, there will be a problem that the two adjacent pieces cannot be effectively adsorbed and sealed. Therefore, soft magnetic strips are set on both sides of the curtain body, and soft magnetic strips are used for adsorption and sealing. However, some technical problems will arise during the specific production:

[0004] 1. When wrapping the soft magnetic strips on the side of the curtain body, the soft magnetic strips need to be fixed, but they are generally fixed by manual welding or sewing, which is labor-intensive and inefficient.

[0005] 2. When fixing the soft magnetic strips, whether welding or sewing, it is necessary to apply pressure to the edge along the length direction and move it at the same time, which will cause the edge to deviate and cause wrinkles on the surface of the thermal insulation curtain. If the wrinkles are severe, it will affect the thermal insulation performance. Summary of the invention

[0006] The technical problem to be solved by the present invention is: how to solve the problem that the edge strip is prone to deviation and causes wrinkles when the soft magnetic strip is wrapped on the side of the curtain body.

[0007] In order to solve the above technical problems, the inventors have obtained the technical solution of the present invention through practice and summary. The present invention adopts the following technical solution:

[0008] A thermal insulation curtain processing system, comprising:

[0009] The curtain outer release mechanism includes a curtain outer release frame, a curtain outer release roller is installed on the curtain outer release frame, a curtain body is wound on the curtain outer release roller, an external discharge motor is installed on the curtain outer release frame, and the output end of the external discharge motor drives the curtain outer release roller to release the curtain body through a reducer;

[0010] The slotting mechanism includes a support frame, an upper beam and a lower beam are arranged on the support frame, the area between the upper beam and the lower beam is the curtain body passing area, the upper beam and the lower beam are both equipped with slotting frames, and the slotting frames are equipped with two groups of symmetrically distributed slotting tools and a motor that drives the slotting tools to rotate;

[0011] The soft magnetic strip external release mechanism includes an independent mounting frame located on both sides of the curtain body, on which a second external discharge motor and a first side pressure roller are mounted, the output end of the second external discharge motor is connected to a soft magnetic strip external release roller via a speed reducer, a soft magnetic strip is wound on the soft magnetic strip external release roller, and the first side pressure roller presses the externally released soft magnetic strip against the side of the curtain body, and the external release speed of the second external discharge motor is the same as that of the first external discharge motor;

[0012] The edge strip outward-feeding mechanism includes an external discharge motor 3, a side pressure roller 2, and an inward-turning pressure roller, which are located on both sides of the curtain body and installed on the mounting frame. The output end of the external discharge motor 3 is connected to the edge strip outward-feeding roller via a reducer. The edge strip is wound on the edge strip outward-feeding roller. The side pressure roller 2 abuts the outward-feeding edge strip against the outside of the soft magnetic strip. The inward-turning pressure roller turns the edge strip inward and cooperates with the notch on the surface of the curtain body. The outward-feeding speed of the external discharge motor 3 is the same as that of the external discharge motor 1.

[0013] The edging-curtain hot melt mechanism includes an upper molding plate and a lower molding plate. An outwardly convex hot melt body is arranged on the opposite side of the upper molding plate and the lower molding plate. The outwardly convex hot melt body forms a hot melt groove one and a hot melt groove two on the edging strip respectively, and the hot melt groove one and the hot melt groove two are staggered along the length direction of the curtain body.

[0014] In order to realize the grooving of curtains of different thickness specifications and the adjustment of the grooving thickness, the grooving mechanism also includes two sets of flat rollers independently arranged on the front and rear sides of the grooving frame, and the two sets of flat rollers are used to horizontally transport the curtain body;

[0015] The groove planing mechanism also includes a lifting cylinder, one end of which is rotatably mounted on the groove planing frame, and the other end of which is rotatably mounted on the corresponding crossbeam.

[0016] In order to achieve effective cooperation between the edge strip and the planing groove, since the curtain body has a certain toughness, if the vertical groove is planed, the matching surface will be tilted outward, which is not conducive to the effective cooperation between the edge strip and the planing groove. The angle between the axis of the rotating shaft of the planing groove tool and the horizontal plane is 1-5°, and the rotating shaft is arranged obliquely downward along the side close to the middle of the curtain body.

[0017] In order to ensure the accurate planing of the groove matching surface, a blowing plate is installed on the groove frame. The blowing plate is provided with a number of settings facing the bottom of the groove, and the blowing plate is externally connected to an air supply pump. High-pressure blowing is performed through the blowing plate to ensure that one side of the matching surface will not be warped upward when the curtain body is planed.

[0018] A negative pressure collection nozzle is installed on the planing frame to collect and process the debris near the slot.

[0019] In order to achieve effective cooperation between the hemming strip and the planing groove matching surface, the inward-turned pressure roller is horizontally arranged and one end close to the middle of the curtain body is obliquely arranged backward. The inward-turned pressure roller includes an inner core and an outer cylinder. The outer cylinder has several groups of negative pressure air holes evenly distributed around the circumference. The inner core is fixedly mounted on the mounting frame and is hollow inside. A negative pressure port communicating with the interior is arranged on the front lower side of the inner core. The negative pressure port is used to communicate with the negative pressure air holes in the corresponding area on the outer cylinder. One end of the inner core is connected to an air pump through a pipeline, and the other end is a closed end.

[0020] In order to achieve effective hot melting of the edging strip and the curtain body and surface shaping of the hot melting area, the lower forming plate and the upper forming plate are provided with installation grooves on the side facing the curtain body, and spring parts are provided in the installation grooves. The free ends of the spring parts are connected with externally protruding hot melt bodies, and internal connecting parts are provided between the externally protruding hot melt bodies and the installation grooves.

[0021] An upward guide groove and a downward guide groove are arranged on the inner wall of the installation groove, a reverse groove 1 is arranged on the top of the upward guide groove, and a reverse groove 2 is arranged on the top of the downward guide groove, the free ends of the reverse groove 1 and the reverse groove 2 intersect, and the upward guide groove and the downward guide groove intersect at one end close to the curtain body, the internal connecting part includes a connecting rod and connecting heads arranged at both ends of the connecting rod, the connecting rod is a slender rod, one connecting head is rotatably installed on the side of the convex hot melt body, and the other connecting head moves cyclically along the upward guide groove, the reverse groove 1, the reverse groove 2, and the downward guide groove in sequence.

[0022] Preferably, a connecting tube is slidably fitted in the descending guide groove through a spring, the connecting tube and the descending guide groove are slidably fitted, the connecting tube is externally connected to an air supply device, the inner connecting piece is hollow, capillaries are arranged inside the external convex hot melt, the capillaries extend to the side of the external convex hot melt facing the curtain body, one of the connecting heads is socket-fitted with the connecting tube, and the other connecting head is connected to the capillary holes.

[0023] Preferably, the descending guide groove is provided with a vertical guide portion located at the top and having a uniform depth, and a disengagement guide portion located at the bottom and having a gradually decreasing depth, and the connector and the connecting pipe are socket-fitted in the vertical guide portion and separated in the disengagement guide portion.

[0024] A method for processing a thermal insulation curtain, the processing steps are as follows:

[0025] Step 1: Open the curtain

[0026] Install the curtain body release roller on the output end of the external discharge motor, and drive the curtain body release roller to release the curtain body through the reducer;

[0027] Step 2: Grooving the curtain surface

[0028] The lifting cylinder drives the planing frame to deflect toward the side close to the curtain body until the planing tool moves down to the required planing depth. The motor drives the planing tool to rotate at high speed. The curtain body is horizontally transported by two sets of level rollers and planed by the planing tool.

[0029] While the groove is being planed, the air supply pump stabilizes the pressure and delivers high-pressure gas to the blowing plate. The high-pressure gas blows through the blowing port to stably blow the curtain body on the matching surface side to ensure that the curtain body on the matching surface side will not turn outward.

[0030] Step 3: Place the soft magnetic strip outside

[0031] The soft magnetic strip external roller is installed on the mounting frame in advance and connected to the output end of the external discharge motor 2. The external discharge speed of the external discharge motor 3 is the same as that of the external discharge motor 1. The side pressure roller 1 presses the external soft magnetic strip against the side of the curtain body.

[0032] Step 4: Place the edging strips outside

[0033] The edge strip outward roller is installed on the mounting frame in advance and connected to the output end of the external discharge motor 3. The outward speed of the external discharge motor 3 is the same as that of the external discharge motor 1. The side pressure roller 2 makes the outward edge strip contact the outside of the soft magnetic strip. The inward pressure roller turns the edge strip inward and matches it with the notch on the surface of the curtain body. The negative pressure pores of the outer cylinder absorb the edge strip and lift it to the planing groove area on the curtain body, and match it in the planing groove.

[0034] Step 5, Edge Binding-Curtain Fusion

[0035] The upper forming plate and the lower forming plate are respectively approached to the curtain body under the action of their independently equipped cylinders, and the outwardly protruding hot melt performs hot melting operation on the edge strip and the curtain body. After hot melting, hot melt groove one and hot melt groove two are respectively formed on the edge strip, and hot melt groove one and hot melt groove two are staggered along the length direction of the curtain body.

[0036] Compared with the prior art, the present invention has the following beneficial effects:

[0037] 1. The present invention implements position fixation before hot melting by planing grooves on the curtain body and using the structure of the planed grooves and the edging strips to prevent deviation during hot melting. Then, the soft magnetic strips, edging strips and hot melting are installed in sequence, so that the edging strips are smoothly fused to both sides of the curtain body.

[0038] 2. In order to ensure the quality of the grooving, the present invention sets two sets of level rollers at the front and back to prevent the curtain body from bending and deforming to different depths. Secondly, the grooving tools are symmetrically distributed on the upper and lower sides of the curtain body to form a symmetrical working method, which can further ensure the quality of the grooving.

[0039] 3. In order to ensure the quality of the matching between the hemming strip and the grooving, the grooving tool is offset by 1-5°, so that the matching surface can effectively match the hemming strip. However, there will be other problems, that is, it is impossible to effectively enter and perform matching operations when matching the hemming strip. Therefore, the inventors set the inverted pressure roller at an angle, and then folded the two hemming parts of the hemming strip toward the middle of the curtain body. Although they can get close, they still cannot be effectively matched. By using a combination of negative pressure adsorption of the hemming part on the inverted pressure roller and the inclination of the inverted pressure roller, the adsorbed hemming strip is lifted inward to the middle of the curtain body, so that the effective matching of the hemming strip and the grooving can be completed.

[0040] 4. The present invention also improves the hot melt structure by adopting a flexibly installed convex hot melt structure. The flexible convex hot melt structure can effectively hot-melt the edge part and the curtain part, and can perform two hot-melt operations during hot-melt, which can completely release the fusion stress of the structure.

[0056] Example 1

[0057] A thermal insulation curtain processing system, comprising:

[0058] The curtain outer releasing mechanism 10 comprises a curtain outer releasing frame 11, a curtain outer releasing roller 12 is installed on the curtain outer releasing frame 11, a curtain body is wound on the curtain outer releasing roller 12, an external discharge motor 13 is installed on the curtain outer releasing frame 11, and the output end of the external discharge motor 13 drives the curtain outer releasing roller 12 to release the curtain body through a reducer.

[0059] The groove planing mechanism 20 includes a support frame 21, an upper beam 22 and a lower beam 23 are arranged on the support frame 21, the area between the upper beam 22 and the lower beam 23 is the curtain body passing area, and groove planing frames 24 are installed on the upper beam 22 and the lower beam 23. The groove planing frame 24 is installed with two groups of groove planing tools 25 symmetrically distributed on the left and right and a motor 26 for driving the groove planing tools 25 to rotate.

[0060] The soft magnetic strip releasing mechanism 30 includes an independent mounting frame 31 located on both sides of the curtain body, on which an external discharge motor 2 32 and a side pressure roller 1 33 are mounted, and the output end of the external discharge motor 2 32 is connected to a soft magnetic strip releasing roller 34 via a reducer, and a soft magnetic strip is wound on the soft magnetic strip releasing roller 34, and the side pressure roller 1 33 presses the released soft magnetic strip tightly against the side of the curtain body, and the releasing speed of the external discharge motor 2 32 is the same as the releasing speed of the external discharge motor 13.

[0061] The edging strip outward-feeding mechanism 40 includes an external discharge motor 3 41, a side pressure roller 2 42, and an inward-turning pressure roller 43, which are located on both sides of the curtain body and installed on the mounting frame 31. The output end of the external discharge motor 3 41 is connected to the edging strip outward-feeding roller 44 via a reducer. The edging strip is wound on the edging strip outward-feeding roller 44. The side pressure roller 2 42 presses the outward-feeding edging strip against the outer side of the soft magnetic strip. The inward-turning pressure roller 43 turns the edging strip inward and cooperates with the groove on the surface of the curtain body. The outward-feeding speed of the external discharge motor 3 41 is the same as the outward-feeding speed of the external discharge motor 13.

[0062] The edging-curtain body hot melt mechanism 50 includes an upper molding plate 51 and a lower molding plate 52, each of which has a cylinder separately arranged on the side facing away from the curtain body. An outwardly convex hot melt body 56 is arranged on the opposite side of the upper molding plate 51 and the lower molding plate 52. The outwardly convex hot melt body 56 forms a hot melt groove 1 and a hot melt groove 2 on the edging strip, respectively, and the hot melt groove 1 and the hot melt groove 2 are staggered along the length direction of the curtain body.

[0063] The external discharge motor 13 releases the curtain body with the curtain release roller 12 at a certain speed, and the released curtain body enters the groove planing position, and the groove planing tool 25 is rotated at high speed by the motor 26 to realize the groove planing operation on the curtain body. After groove planing, a matching groove is formed on the curtain body, and the depth of the matching groove is 1.5-3mm, and the side of the matching groove away from the middle of the curtain body is the matching surface; the curtain body enters the soft magnetic strip assembly area, and the external discharge motor 2 32 drives the soft magnetic strip release roller 34 to release the soft magnetic strip through the reducer, and the released soft magnetic strip is tightly fitted to the side of the curtain body under the action of the side pressure roller 1 33; the curtain body enters the edge strip assembly area, and the external discharge motor 3 41 drives the edge strip release roller 44 to release the edge strip through the reducer, and the released edge strip is tightly fitted to the outside of the soft magnetic strip under the action of the side pressure roller 2 42 On the side, the edging part is installed with the edging strip and the matching groove under the action of the inward-turned pressure roller 43, and a matching body is provided on the side of the edging part opposite to the curtain body, and the side of the matching body opposite to the curtain body gradually approaches the side of the curtain body; the edging-curtain body combination enters the hot melt assembly area, and moves close to the curtain body under the action of the upper forming plate 51 and the lower forming plate 52 under the action of the cylinders equipped respectively, and the edging strip and the curtain body are heat-fused by the convex hot melt body 56 thereon, and after hot fusion, hot melt groove one and hot melt groove two are respectively formed on the edging strip, and the hot melt groove one and the hot melt groove two are staggered along the length direction of the curtain body, which can effectively release the fusion stress, and the hot melt groove one and the hot melt groove two both span the matching groove, and the bottom surface of the groove is located in the coverage area of ​​the matching groove in the thickness direction of the curtain body.

[0064] Embodiment 2, based on the above embodiment, makes the following improvements:

[0065] The groove planing mechanism 20 further includes two sets of parallel rollers 60 independently arranged at the front and rear sides of the groove planing frame 24. The two sets of parallel rollers 60 are used to horizontally transport the curtain body, which is beneficial to ensure the consistency of the groove planing depth.

[0066] The groove planing mechanism 20 also includes a lifting cylinder 27, one end of the lifting cylinder 27 is rotatably mounted on the groove planing frame 24, and the other end is rotatably mounted on the corresponding crossbeam. The lifting cylinder 27 is extended and retracted to drive the groove planing tool 25 to adjust its height, thereby achieving adjustment of the groove planing depth.

[0067] The angle between the axis of the rotating shaft of the slotting tool 25 and the horizontal plane is 1-5°, and the rotating shaft is set diagonally downward along the side close to the middle of the curtain body. Since the curtain body is made of PVC and has a certain toughness, if the vertical slotting operation is directly performed on the surface of the curtain body, the top of the matching surface will move outward, which will lead to the problem of easy falling off after the subsequent matching and installation of the edging strip, and the problem of surface wrinkle processing cannot be solved. The redundant slotting is used to achieve the inward movement of the top of the matching surface, forming a hooking form with the edging strip, thereby ensuring that it will not fall off after matching.

[0068] However, the oblique setting during the planing process will aggravate the deformation of the mating surface away from the middle area of ​​the curtain body and move it outward and upward, so that the mating surface is located on the inner side of the set area after processing, making the inclination transition of the mating surface smaller, which is not conducive to effective matching and assembly, and is easy to cause the problem of eversion after matching. Therefore, a blowing plate 28 is installed on the planing frame 24, and a plurality of blowing ports are arranged on the blowing plate 28 toward the bottom of the planing groove. The blowing plate 28 is externally connected to an air supply pump. After the air supply pump is stabilized, it blows the sharp corner part of the outer side of the originally everted mating surface inward, effectively reducing the eversion amount and effectively alleviating the problem of the eversion transition of the mating surface. In this way, the strength of the top of the mating surface can be guaranteed, and the eversion problem is not easy to occur.

[0069] A negative pressure collection nozzle 29 is installed on the planing frame 24 to collect and process debris near the slot opening.

[0070] Embodiment 3, based on the above embodiment, makes the following improvements:

[0071] The inward-turned pressure roller 43 is horizontally arranged and one end close to the middle of the curtain body is arranged obliquely backward. The inward-turned pressure roller 43 includes an inner core 431 and an outer cylinder 432. The outer cylinder 432 has a plurality of groups of negative pressure air holes 433 evenly distributed around the circumference. The inner core 431 is fixedly mounted on the mounting frame 31 and is hollow inside. A negative pressure port 434 communicating with the inside is arranged on the front lower side of the inner core 431. The negative pressure port 434 is used to communicate with the negative pressure air holes 433 in the corresponding area on the outer cylinder 432. One end of the inner core 431 is connected to an air pump via a pipeline, and the other end is a closed end. An external vacuum pump is connected through the inner core 431 to communicate with the negative pressure port 434 and the negative pressure air hole 433 to adsorb the edging strip on the front lower side. Since the outer tube 432 is arranged obliquely to the rear side, the edging part can be transported inward and pulled toward the middle of the curtain body until it enters the matching groove. After the elasticity of the edging part is restored, the matching gap can be eliminated and the matching quality can be effectively ensured.

[0072] Embodiment 4, based on the above embodiment, makes the following improvements:

[0073] The lower forming plate 52 and the upper forming plate 51 are provided with a mounting groove 53 on one side facing the curtain body, a spring member 54 is provided in the mounting groove 53 , a protruding hot melt 56 is connected to the free end of the spring member 54 , and an inner connecting member 55 is provided between the protruding hot melt 56 and the mounting groove 53 .

[0074] An upward guide groove 531 and a downward guide groove 532 are arranged on the inner wall of the installation groove 53, a reverse groove 1 533 is arranged on the top of the upward guide groove 531, and a reverse groove 2 534 is arranged on the top of the downward guide groove, the reverse groove 1 533 and the reverse groove 2 534 intersect at their free ends, and the upward guide groove 531 and the downward guide groove 532 intersect at one end close to the curtain body, the inner connecting member 55 includes a connecting rod and connecting heads arranged at both ends of the connecting rod, the connecting rod is a slender rod, one connecting head is rotatably installed on the side of the convex hot melt 56, and the other connecting head moves cyclically along the upward guide groove 531, the reverse groove 1 533, the reverse groove 2 534, and the downward guide groove 532 in sequence.

[0075] On this basis, the following improvements are made: the downward guide groove 532 is provided with a connecting tube 535 through a spring sliding fit, the connecting tube 535 and the downward guide groove 532 are slidably fitted, the connecting tube is externally connected to an air supply device, the inner connecting piece 55 is hollow, the outer convex hot melt 56 is provided with capillary holes, the capillary holes extend to the side of the outer convex hot melt 56 facing the curtain body, one of the connectors is socket-fitted with the connecting tube 535, and the other connector is connected to the capillary holes. The outer convex hot melt 56 is separately equipped with a power supply and an electric heating wire is embedded inside, and the outer convex hot melt 56 is heated to a temperature capable of hot-melting the edge strip and the curtain body through the power supply and the electric heating wire. This heating and temperature control method is a mature technology on the market, so it is not elaborated in detail.

[0076] The descending guide groove 532 is provided with a vertical guide portion 5321 located at the top and with a uniform depth, and a disengagement guide portion 5322 located at the bottom and with a gradually decreasing depth. The connector and the connecting pipe 535 are socket-fitted in the vertical guide portion 5321 and are separated in the disengagement guide portion 5322 .

[0077] When the lower molding plate 52 and the upper molding plate 51 approach the curtain body, the convex hot melt 56 will first contact the edge part. As they continue to approach, the spring body 54 is gradually compressed. At the same time, the convex hot melt 56 enters the installation groove 53, enters the connector along the upward guide groove 531 (the depth gradually decreases along the direction of movement of the connector, and the connecting rod gradually undergoes a slight bending deformation) and enters the beginning of the reverse groove 533 (the thickness gradually decreases along the direction of movement of the connector). At this time, the initial hot melt operation is completed, and the lower molding plate 52 and the upper molding plate 51 are away from the curtain body. The connector along The reverse groove 1 533 (under the action of gravity of the convex hot melt 56) descends to the starting end of the reverse groove 2 534, and the lower molding plate 52 and the upper molding plate 51 approach the curtain body again. The connector reverse groove 2 534 (the depth gradually decreases along the running direction of the connector) enters the starting end of the downward guide groove 532. At this time, the connector will be socketed with the connecting pipe 535, and the lower molding plate 52 and the upper molding plate 51 will move away from the curtain body again. The capillary pores will be connected with the connecting pipe, connecting the inside, and transporting gas into the hot melt groove to separate the edge wrapping part and the convex hot melt 56.

[0078] A method for processing a thermal insulation curtain, the processing steps are as follows:

[0079] Step 1: Open the curtain

[0080] Install the curtain body release roller 12 on the output end of the external discharge motor 13, and drive the curtain body release roller 12 to release the curtain body through the reducer;

[0081] Step 2: Grooving the curtain surface

[0082] The lifting cylinder 27 drives the groove planing frame 24 to deflect toward the side close to the curtain body until the groove planing tool 25 moves downward to the required groove planing depth position, and the motor 26 drives the groove planing tool 25 to rotate at high speed, and the curtain body is horizontally transported by two sets of level rollers 60, and the groove planing tool 25 performs the groove planing operation;

[0083] While the groove is being planed, the air supply pump stabilizes the pressure and delivers high-pressure gas to the blowing plate 28. The high-pressure gas blows the curtain body on the matching surface side through the blowing port to stably blow the curtain body on the matching surface side, ensuring that the curtain body on the matching surface side will not turn outward.

[0084] Step 3: Place the soft magnetic strip outside

[0085] The soft magnetic strip external roller 34 is installed on the mounting frame 31 in advance and connected to the output end of the external discharge motor 2 32. The external discharge speed of the external discharge motor 3 41 is the same as that of the external discharge motor 1 13. The side pressure roller 1 33 makes the external soft magnetic strip close to the side of the curtain body.

[0086] Step 4: Place the edging strips outside
