Description

Technical Field

[0001] This utility model belongs to the field of honeycomb curtains, and in particular relates to a processing equipment for honeycomb curtain rope holes. Background Technology

[0002] The structure of traditional honeycomb curtains, such as Figure 10 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 (108) at both the top and bottom. The honeycomb fabric of the honeycomb blind is connected to the upper and lower 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 are 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] During the up-and-down movement of the poles, the rope rubs against the edge of the rope passage hole, and the rope surface is easily scratched by the edge of the rope passage hole, causing the honeycomb blind to rise and fall unevenly. Furthermore, the rope passage hole is easily cut by the sliding rope, and the rope entering the gap can easily get stuck, also causing uneven rising and falling of the honeycomb blind. During the rope threading process, the rope needs to be bent twice after entering the pole before it can exit. The threading process requires extreme care, and sometimes even tooling is needed to guide the rope ends out of the pole, resulting in poor threading efficiency and reducing the assembly efficiency of the honeycomb blind. Traditionally, the rope passage holes on the poles are machined by drilling, requiring four holes to be drilled on each pole, which is inefficient and leads to low production efficiency of the honeycomb blind.

[0004] To address the shortcomings of traditional honeycomb blinds, such as uneven lifting, low assembly efficiency, and low production efficiency, improvements are made to the traditional honeycomb blinds. The improvement plan is as follows: like Figures 4 to 9 As shown, the improved honeycomb curtain includes two rods, one above the other, with a honeycomb fabric 100 between the two rods, and two ropes 101 passing through the honeycomb fabric 100 between the two rods.

[0005] 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.

[0006] like Figure 2 and Figure 3As 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.

[0007] like Figure 4 As 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.

[0008] 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.

[0009] 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.

[0010] 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.

[0011] 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.

[0012] 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.

[0013] Initially, the back cover 103 is not installed. 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; the specific threading method can be found in [link to documentation]. Figure 4The 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.

[0014] In the improved honeycomb blind, the rods are now a split structure, consisting of a main rod and a back cover. During threading, the back cover separates from the main rod, exposing the through holes, making operation convenient, providing a clear view, and significantly improving threading efficiency and assembly efficiency. A guide component corresponding to the rope holes is installed inside the main rod. The rope passes through the rope holes after going around the rollers on the guide component. The rope holes no longer bend the rope or make contact with it. When raising and lowering the honeycomb blind, the rope passes over the smooth roller surface, preventing it from being scratched. The rollers rotate with the rope during movement, also preventing them from being cut or notched, ensuring smooth raising and lowering of the honeycomb blind. However, the rope holes on the main rod are still machined by drilling, requiring four drilling operations. This means the machining efficiency of the rope holes is not improved and remains relatively low, hindering the production efficiency of the improved honeycomb blind. Utility Model Content

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: A honeycomb curtain rope hole processing equipment is used for punching rope holes 108 on the main rod 102, such as... Figures 1 to 3 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.

[0035] 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 blanking holes 208 are provided on the positioning block 206. The diameter of the blanking holes 208 is matched with the diameter of the upper and lower punches. The position of the blanking holes 208 corresponds to the position of the rope hole. A discharge hole 209 communicating with the blanking 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 blanking holes 208.

[0036] The inner wall of the blanking hole 208 is provided with a spherical guide protrusion 212, which is located in the axial direction of the discharge hole 209.

[0037] 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.

[0038] 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.

[0039] The punch press presses down the upper template 200, 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 through the rope hole at the bottom of the main rod 102 and enters the lower end of the blanking hole 208, 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 through the rope hole at the top of the main rod 102 and enters the upper end of the blanking hole 208. When the upper punch 201 first punches through the rope hole at the top of the main rod 102 and enters the upper end of the blanking hole 208, 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 through the rope hole at the bottom of the main rod 102 and enter the lower end of the blanking hole 208.

[0040] After multiple punching operations, the accumulated waste material moves towards the center of the punching 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.
