Description

Technical Field

[0001] This invention belongs to the field of honeycomb curtains, and particularly relates to a honeycomb curtain and a punching device for honeycomb curtains. Background Technology

[0002] The existing honeycomb curtain structure, such as Figure 7 As shown, the structure includes two aluminum profile rods, one at the top and one at the bottom. Each rod has a through hole and two cord holes at the top and bottom. The honeycomb fabric of the honeycomb blind is connected to the top and bottom rods respectively. Two cords (transparent plastic) are used. For any cord, first pass one end through the cord hole at the top of the upper rod, then bend it and proceed horizontally along the through hole, down through the cord hole at the bottom of the upper rod, through the fabric, into one of the cord holes at the top of the lower rod, then bend it again and proceed horizontally along the through hole, finally passing through the cord hole at the bottom of the lower rod. The two ends of the cords are fixed to the top and bottom of the window and kept taut. Because the cords bend multiple times as they pass through the honeycomb blind, they provide friction, allowing the blind to maintain its height at any point. To open the honeycomb blind, simply pull up the upper rod or down the lower rod.

[0003] According to customer feedback, during the up-and-down movement of the poles, the rope rubs against the rope hole, and the surface of the rope is easily scratched by the edge of the rope hole, causing the honeycomb curtain to rise and fall unevenly. In addition, the rope hole is easily cut by the sliding rope, and the rope can easily get stuck in the gap, causing the honeycomb curtain to rise and fall unevenly.

[0004] In actual production, it was found that during the rope threading process, the rope needs to be bent twice after entering the pole before it can exit the pole. The threading process requires great care and may even require the use of tooling to guide the rope ends out of the pole. The threading efficiency is very poor, which reduces the assembly efficiency of the honeycomb curtain.

[0005] In addition, the rope holes on the existing poles are made by drilling, which requires drilling four holes on each pole. This process is inefficient and results in low production efficiency for honeycomb curtains.

[0006] Therefore, existing honeycomb curtains have drawbacks such as unsmooth lifting and lowering, low assembly efficiency, and low production efficiency. Summary of the Invention

[0007] The purpose of this invention is to provide a honeycomb curtain and a punching device for the honeycomb curtain. This invention has the advantages of easily ensuring smooth lifting and lowering, high assembly efficiency, and high production efficiency.

[0008] The technical solution of the present invention: A honeycomb curtain includes two rods, upper and lower, with honeycomb fabric between the two rods. Two ropes passing through the honeycomb fabric are provided between the two rods. Each rod includes a main rod, a back cover, and two guide components. The rear side of the main rod has a through groove, and the back cover is located at the opening of the through groove and is detachably connected to the main rod. A through hole is formed between the back cover and the main rod. The guide components include two rollers, upper and lower, both located in the through hole, and a base plate slidably connected to the main rod. The rollers are rotatably connected to the base plate. The upper and lower sides of the guide components have rope holes passing through the main rod.

[0009] In the aforementioned honeycomb curtain, the upper and lower sides of the opening of the through groove are provided with stepped grooves, and the upper and lower edges of the back cover enter the corresponding stepped grooves respectively. The inner walls of the upper and lower sides of the through groove are recessed inward to form a locking groove. The locking groove is provided with a buckle for connecting the back cover, and the two rollers of the guide assembly are located between the two buckles.

[0010] In the aforementioned honeycomb curtain, the inner walls of the upper and lower sides of the through groove both protrude inward to form a guide strip close to the through groove. The guide strip and the bottom surface of the through groove form a sliding groove. The upper and lower sides of the bottom plate are provided with sliding strips located in the sliding groove.

[0011] In the aforementioned honeycomb curtain, the rollers are rotatably connected to the base plate via pins. The base plate is provided with two protruding posts, and the protruding posts are provided with set screws that connect to the main rod.

[0012] In the aforementioned honeycomb curtain, the two protruding pillars are located on the same horizontal side of the two rollers.

[0013] In the aforementioned honeycomb curtain, an annular groove is provided on the outer circumferential surface of the roller, a cap fixed to the pin is provided at the outer end of the roller, and a damping ring through which the pin passes is provided between the roller and the base plate.

[0014] A punching device for honeycomb curtains, used for processing rope holes in front-speed honeycomb curtains, includes a punch press, the punching end of the punch press is provided with an upper template, the bottom of the upper template is provided with two upper punches, and a pressure block is provided on one side of the bottom of the upper template. The punch press has a lower template on its table, a lifting plate above the lower template, two lower punches on the lower template, and two upper punches located below the two upper punches. A guide mechanism and a return mechanism are provided between the lower template and the lifting plate. A positioning block is provided on the upper side of the lifting plate, and a support block is provided on the bottom side of the positioning block. The positioning block has two vertical discharge holes, and a discharge hole communicating with the discharge holes is provided on the side wall of the positioning block.

[0015] In the aforementioned punching equipment for honeycomb curtains, the discharge hole is inclined, and the upper end of the discharge hole is connected to the drop hole.

[0016] In the aforementioned punching equipment for honeycomb curtains, a spherical guide protrusion is provided on the inner wall of the discharge hole, and the guide protrusion is located in the axial direction of the discharge hole.

[0017] In the aforementioned honeycomb curtain punching equipment, the guiding mechanism includes multiple guide posts fixed to the lower template, the guide posts passing through the lifting plate, and the return mechanism includes a spring located outside the guide posts, the spring being located between the lifting plate and the lower template, and the spring being spiral-shaped.

[0018] Compared with the prior art, the present invention mainly makes the following improvements based on the existing honeycomb curtain: First, the rods of the honeycomb curtain have been improved. The rods are now a split structure, consisting of a main rod and a back cover. When threading the wires, the back cover separates from the main rod, exposing the through holes of the rods. This makes operation convenient, provides a clear view, greatly improves threading efficiency, and increases assembly efficiency.

[0019] Secondly, a guide component corresponding to the rope passage hole is installed inside the rod. The rope passes through the rope passage hole after going around the roller on the guide component. The rope passage hole no longer bends the rope or makes contact with it. When the honeycomb blind is raised or lowered, the rope passes over the smooth roller surface, which is not easily scratched. The roller rotates with the rope during movement, which is also not easily cut into the roller, making the honeycomb blind rise and fall smoothly. For honeycomb blinds with different widths, the horizontal distance of the rope passage hole on the rod is different. The position of the guide component in the rod is adjustable, which is convenient and can be used for honeycomb blinds of different widths, making it widely applicable.

[0020] Furthermore, based on the improved rod structure, the rope holes on the rods have the possibility of being punched. Based on the improved rod mechanism, this invention also provides a punching device that can punch out the four rope holes on the rods in one go and realize the automatic discharge of punching waste, which greatly improves production efficiency.

[0021] In summary, the present invention has the advantages of easily ensuring smooth lifting and lowering, high assembly efficiency, and high production efficiency. Attached Figure Description

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0034] Example 1: A honeycomb curtain, such as Figure 1 As shown, it includes two rods, one above the other, with a honeycomb fabric 100 between them. Two ropes 101 pass through the honeycomb fabric 100 between each rod. Its features are as follows: The rod consists of a main rod 102, a rear cover 103, and two guide assemblies. Both the main rod 102 and the rear cover 103 are made of aluminum profiles.

[0035] like Figure 2 and Figure 3 As shown, the main rod 102 is provided with wire grooves 121 on both the upper and lower sides, and a through groove 104 is provided on the rear side of the main rod 102. The rear cover 103 is located at the opening of the through groove 104, and a through hole 105 is formed between the rear cover 103 and the main rod 102.

[0036] like Figure 4As shown, the guide assembly includes two rollers 106 located in the through hole 105 and a base plate 107 slidably connected to the main rod 102. The rollers 106 are rotatably connected to the base plate 107 via a pin 115. The rollers 106 are made of bearing steel. The guide assembly has rope holes 108 passing through the main rod 102 on both the upper and lower sides.

[0037] The upper and lower sides of the opening of the through groove 104 are provided with stepped grooves 109. The upper and lower edges of the rear cover 103 enter the corresponding stepped grooves 109 respectively. The inner walls of the upper and lower sides of the through groove 104 are recessed inward to form a slot 110. The slot 110 is provided with a buckle 111 for connecting the rear cover 103. The two rollers 106 of the guide assembly are located between the two buckles 111.

[0038] The inner walls of the upper and lower sides of the through groove 104 protrude inward to form a guide strip 112 close to the through groove 104. The guide strip 112 and the bottom surface of the through groove 104 form a sliding groove 113. The upper and lower sides of the base plate 107 are provided with slide bars 114 located in the sliding groove 113.

[0039] The base plate 107 has two protrusions 116, which are located on the same horizontal side of the two rollers 106. A set screw 117 connecting the main rod 102 is located at each protrusion 116. The protrusions 116 increase the contact area between the set screw 117 and the base plate 107, preventing stripping. The base plate 107 is an injection-molded part. The base plate 107 can move when the set screw 117 is loosened.

[0040] The outer circumferential surface of the roller 106 is provided with an annular groove 118, and the outer end of the roller 106 is provided with a cap 119 fixed to the pin 115. A damping ring 120 is provided between the roller 106 and the base plate 107, through which the pin 115 passes. The damping ring 120 is made of rubber ring, which is pre-compressed and coated with grease. The elasticity of the rubber ring makes the rotation of the roller 106 have a certain resistance.

[0041] Assembly method: Two holes are pre-drilled on the honeycomb fabric 100, and the distance between the two holes is the horizontal distance between the rope holes 108.

[0042] Initially, do not install the back cover 103. Loosen the set screw and slide the guide assembly to the corresponding rope hole 108. Assemble the two ropes 101 according to the existing threading method; see [link to threading instructions] for details. Figure 1 The rope 101 passes over the roller 106 on the corresponding guide assembly and is located within the annular groove 118. The upper end of the rope 101 is first fixed to the top of the window, and after it is threaded through, the lower end is fixed to the bottom of the window. Finally, the back cover 103 is installed. The back cover 103 serves a decorative purpose and also makes the back of the rod flat, facilitating the up-and-down movement of the rod by hand.

[0043] Example 2: A punching device for a honeycomb curtain, used for processing the rope holes 108 on the main rod 102 of Example 1, such as... Figure 8 and Figure 9 As shown, it includes a punch press (punch press omitted), the punching end of the punch press is provided with an upper template 200, the bottom of the upper template 200 is provided with two upper punches 201, and a pressure block 202 is provided on one side of the bottom of the upper template 200.

[0044] The punch press table is provided with a lower template 203, and a lifting plate 204 is provided above the lower template 203. Two lower punches 205 are provided on the lower template 203, and the two lower punches 205 are respectively located below two upper punches 201. A positioning block 206 is provided on the upper side of the lifting plate 204. The positioning block 206 cooperates with the through groove of the main rod 102. A support block 207 fixed to the lifting plate 204 is provided on the bottom side of the positioning block 206. Two vertical dropping holes 208 are provided on the positioning block 206. The position of the dropping holes 208 corresponds to the position of the rope hole. A discharge hole 209 communicating with the dropping holes 208 is provided on the side wall of the positioning block 206. The discharge hole 209 is inclined and the upper end of the discharge hole 209 is connected to the dropping hole 208.

[0045] The inner wall of the discharge hole 208 is provided with a spherical guide protrusion 212, which is located in the axial direction of the discharge hole 209.

[0046] A guiding mechanism and a return mechanism are provided between the lower template 203 and the lifting plate 204. The guiding mechanism includes multiple guide posts 210 fixed to the lower template 203, which pass through the lifting plate 204. The return mechanism includes a spring 211 located outside the guide posts 210, between the lifting plate 204 and the lower template 203, and the spring 211 is spiral-shaped. The upper end of the guide post 210 passes horizontally through a limiting pin to prevent the lifting plate 204 from separating from the guide post 210.

[0047] Instructions for use: Take the main rod 102 without the rope hole 108, and insert the through groove 104 into the positioning block 206. In the width direction, the lower end of the main rod 102 contacts the support block 207 for positioning. In order to make the position of the punched rope hole 108 accurate, a positioning pin for positioning the main rod 102 in the longitudinal direction can be set on the lifting plate 204.

[0048] The upper template 200 is pressed down by the punch press. The upper punch 201 first contacts the main rod 102, then the spring 211 is compressed, and the lower punch 205 then contacts the main rod 102. As the upper template 200 continues to descend, when the lower punch 205 first punches the rope passage hole at the bottom of the main rod 102, the lifting plate 204 continues to descend until it contacts the limit block 213, and the main rod 102 stops descending. The upper punch 201 punches the rope passage hole at the top of the main rod 102. When the upper punch 201 first punches the rope passage hole at the top of the main rod 102, the lifting plate 204 continues to descend, causing the pressure block 202 to contact the positioning block 206. The positioning block 206 drives the main rod 102 to descend, causing the lower punch 205 to punch the rope passage hole at the bottom of the main rod 102.

[0049] After multiple punching operations, the accumulated waste material moves towards the center of the discharge hole 208. When it passes the guide protrusion 212, it receives a horizontal force and enters the discharge hole 209, where it falls freely. The discharge is automatic, improving punching efficiency.
