Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat preservation curtain processing technology, and in particular to a double-sided edge banding device for magnetic heat preservation door curtains. Background Technology
[0002] Existing thermal insulation curtains are generally made of PVC or cotton-filled materials. Cotton-filled curtains offer superior insulation performance and ease of use compared to PVC, making them more popular with consumers. Most existing cotton-filled thermal insulation curtains have a transparent window structure installed, such as the magnetic cotton curtain disclosed in CN208709278U and the thermal insulation curtain disclosed in CN202941894U. However, neither of these describes how to assemble the transparent window structure and the curtain body. Therefore, the inventor proposes a magnetic thermal insulation curtain that uses a double-sided edge-sealing device to achieve the assembly of the transparent window structure and the curtain body. Utility Model Content
[0003] The technical problem to be solved by this utility model is:
[0004] How to complete the assembly and processing of transparent windows and curtains.
[0005] To solve the above-mentioned technical problems, the inventors, through practice and summarization, derived the technical solution of this utility model, which adopts the following technical solution:
[0006] A double-sided edge banding device for a magnetic heat-insulating door curtain includes:
[0007] The upper vertical plate is equipped with a lining structure and a folding structure arranged from top to bottom.
[0008] The lower horizontal plate is provided with a second edge-trimming structure and a second folding structure arranged from front to back.
[0009] The lower positioning plate has one end mounted on the lower horizontal plate and the other end equipped with a positioning structure.
[0010] The upper positioning plate has one end mounted on the lower horizontal plate and the other end equipped with positioning structure two.
[0011] Positioning structure one is located below positioning structure two, and their projections on the horizontal plane overlap.
[0012] More specifically, both the first folding structure and the second folding structure include a folding plate, both sides of which are folded inward to form a folded body. An intermediate plate is installed between the two folded bodies, and the intermediate plate is located on the opposite side of the first folding structure and the second folding structure.
[0013] More specifically, the two ends of the intermediate plate are folded and bent toward the side opposite to the folding plate to form guide grooves, and the free ends of the guide grooves are connected to the folding body.
[0014] More specifically, both the first and second edge-shaping structures are S-shaped structures.
[0015] More specifically, the top of positioning structure one and the bottom of positioning structure two are connected. The free ends of positioning structure one and positioning structure two gradually deviate upward from the lower horizontal plate and form a U-shaped part at the end. The overlap width of the U-shaped parts of positioning structure one and positioning structure two is about one-third to two-thirds of the minimum width of the folding structure.
[0016] More specifically, the upper vertical plate includes a front plate arranged front to back and a rear plate arranged vertically. The front plate is provided with guide grooves distributed front to back, the rear plate is provided with guide grooves distributed vertically, and the lower horizontal plate is provided with guide grooves distributed left to right.
[0017] More specifically, both the folding plate and the middle plate include a middle plate and adjusting plates symmetrically distributed on both sides of the middle plate. The adjusting plates are equipped with clamping components, and the middle plate has symmetrically distributed adjusting grooves. The clamping components are slidably fitted in the adjusting grooves.
[0018] More specifically, the two sets of adjusting plates are provided with rectangular teeth on opposite sides, and the two sets of rectangular teeth are mutually inserted and adapted to each other.
[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] 1. This utility model adopts a double-sided edge-wrapping structure, which allows for simultaneous edge-wrapping at the joint between the curtain structure and the transparent window structure. After the edge-wrapping is completed, the edge strip is sewn immediately, so that the joint is hidden inside the edge strip, ensuring the stability of the curtain and transparent window structure inside the edge strip, and also improving the aesthetics of the product.
[0021] 2. This utility model forms folding bodies at both ends of the folding plate to facilitate the inward folding of the edge strip. The middle plate can restrict the edge strip of the folded part to prevent excessive bending and deformation during the inward folding of the edge strip, which may cause deviation or uneven folding width on both sides.
[0022] 3. This utility model forms guide grooves at both ends of the middle plate, and connects the guide grooves with the folding body to form a snap fastener inside the edge banding strip. During sewing, the snap fastener can be sewn inside the edge banding strip, thereby completing the assembly and edge banding sewing operation.
[0023] 4. Guide grooves are provided on both the upper vertical plate and the lower horizontal plate of this utility model. The position of the folding structure relative to the stitching structure can be adjusted appropriately using the guide grooves.
[0024] 5. Both the folding plate and the middle plate of this utility model adopt a structure with adjustable width on the left and right sides, and the width can be adjusted left and right to adapt to different overlap widths. Attached Figure Description

[0036] Example 1
[0037] like Figure 1 As shown, a double-sided edge banding device for a magnetic heat-insulating door curtain includes:
[0038] The upper vertical plate 10 is provided with an edge-trimming structure 11 and a folding structure 12 arranged from top to bottom.
[0039] The lower horizontal plate 20 is provided with a second edge-trimming structure 21 and a second folding structure 22 arranged sequentially from front to back.
[0040] The lower positioning plate 30 has one end mounted on the lower horizontal plate 20 and the other end provided with a positioning structure 31.
[0041] The upper positioning plate 40 has one end mounted on the lower horizontal plate 20 and the other end provided with a positioning structure 41.
[0042] Among them, positioning structure 31 is located below positioning structure 41 and the projections of the two on the horizontal plane overlap.
[0043] Both edge-fixing structure 11 and edge-fixing structure 21 are S-shaped structures used to constrain the left and right positions of the edge strip and prevent deviation during transportation.
[0044] One side of the curtain is positioned by positioning structure 31, and one side of the transparent window is positioned by positioning structure 41. After the curtain and transparent window are positioned, they are conveyed together towards the folding structure. During the conveying process, the curtain and transparent window overlap vertically. One binding strip is edged by edge-finding structure 11, then folded by folding structure 12 to complete the folding on both sides, and then pressed onto the upper side of the overlapping area. Similarly, the other binding strip is edged by edge-finding structure 21, then folded by folding structure 22 to complete the folding on both sides, and then pressed onto the lower side of the overlapping area. The two binding strips are sewn together by the sewing machine head (sewing machine). Figure 6 As shown.
[0045] Example 2
[0046] The following improvements were made based on Example 1, such as... Figure 2As shown, both the first folding structure 12 and the second folding structure 22 include a folding plate 50. Both sides of the folding plate 50 are folded inward to form a folded body 51. An intermediate plate 52 is installed between the two folded bodies 51. The intermediate plate 52 is located on the opposite side of the first folding structure 12 and the second folding structure 22.
[0047] During the folding process on both sides of the binding strip, the middle part is prone to bulging to one side due to the force on both sides, which leads to the problem of inconsistent folding width on both sides. The middle plate 52 can restrain the binding strip from bulging to one side and ensure that the folding width on both sides is consistent.
[0048] Example 3
[0049] The following improvements were made based on Example 2, such as... Figure 2 As shown, both ends of the intermediate plate 52 are folded and bent towards the side opposite to the folding plate 50 to form guide grooves 53. The free ends of the guide grooves 53 are connected to the folding body 51. In implementation, the fastener mother and fastener male can be inserted and transported (along with the binding strip) in the two guide grooves 53 respectively. The fastener mother and fastener male can be used to assemble the overlapping part of the curtain and transparent window together. After assembly, the pressing and constraint of the folded edge of the binding strip can be completed. A stable assembly structure can be formed without the use of sewing thread. Figure 7 As shown.
[0050] Example 4
[0051] The following improvements were made based on Example 1, such as... Figure 2 As shown, the top of positioning structure 31 and the bottom of positioning structure 41 are connected. The free ends of positioning structure 31 and positioning structure 41 gradually deviate upward from the lower horizontal plate 20 and form a U-shaped part 54 at the end. The U-shaped part 54 is used for position constraint of the side of the curtain or transparent window to ensure the consistency of the overlapping width and the conveying position. The overlapping width of positioning structure 31 and the U-shaped part 54 of the positioning structure is about one-third to two-thirds of the minimum width of the folding structure.
[0052] Example 5
[0053] The following improvements were made based on Example 1, such as... Figure 1 As shown, the upper vertical plate 10 includes a front plate 101 arranged front to back and a rear plate 103 arranged vertically. The front plate 101 is provided with guide grooves 102 distributed front to back, the rear plate 103 is provided with guide grooves 104 distributed vertically, and the lower horizontal plate 20 is provided with guide grooves 105 distributed left to right. The position of the relative stitching pieces is adjusted by the guide grooves 102, 104, and 105. Specifically, clamping bolts are installed in the guide grooves to fix each plate.
[0054] Example 6
[0055] The following improvements were made based on Example 2, such as... Figures 3 to 5 As shown, both the folding plate 50 and the intermediate plate 52 include a middle plate 58 and adjusting plates 55 symmetrically distributed on both sides of the middle plate 58. A clamping element 57 (bolt) is installed on the adjusting plate 55. Adjusting grooves 56 are symmetrically distributed on the middle plate 58, and the clamping element 57 slides within the adjusting grooves 56. The distance between the two adjusting plates 55 is adjusted by laterally adjusting the position of the adjusting plate 55 relative to the intermediate plate 52, thereby ensuring adaptability to adjustments of different widths.
[0056] More specifically, the two sets of adjustment plates 55 are provided with rectangular teeth 59 on opposite sides. The two sets of rectangular teeth 59 are mutually inserted and adapted to each other. The mutual insertion and adaptation is achieved by using the rectangular teeth 59. The width of the adjustment groove 56 is less than or equal to the length of the rectangular teeth 59, thereby ensuring that the edge strip will not bulge towards the middle plate 58 after adjustment.
[0057] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
