Description

Technical Field

[0001] This utility model relates to the field of zipper production and processing technology, and in particular to a monofilament shaping machine. Background Technology

[0002] A zipper is a common closure device used to connect two edges so that it can be easily opened and closed. It consists of two rows of chains with small teeth that can mesh with each other and close or open through the zipper head. Zipper monofilament is a specific type of monofilament used to make zippers, usually made of polyester material, which has high strength and durability.

[0003] The processing of monofilament requires drying and heat setting. For example, Chinese Patent Publication No. CN214271174U discloses a heating and setting device for polyester monofilament drawing equipment, including a mounting frame. A cylinder is fixedly connected to the inner wall of one side of the mounting frame, and a sliding rod is fixedly connected to one end of the cylinder's pneumatic rod. Two fixing rings are fixedly connected to one side of the mounting frame, and the sliding rod passes through the fixing rings. Multiple second sliding grooves are opened on one side of the sliding rod, and a top block is movably connected within each second sliding groove. A limit block is fixedly connected to one side of the top block. Multiple fixing blocks are fixedly connected to one side of the mounting frame, and multiple first sliding grooves are opened on one side of the mounting frame, with a slider movably connected within each first sliding groove. This invention not only enables the first guide wheel to stretch the polyester filament during the setting process, improving the quality of polyester filament production, but also prevents the polyester filament from rubbing against the mounting box through the second guide wheel, avoiding damage to the polyester filament. Furthermore, the base supports the mounting frame, providing good moisture protection.

[0004] In actual operation, the spacing between multiple heating boxes is adjusted by lead screws and guide rods. Adjusting by rotating the lead screw is slow, and the lead screw is inconvenient to maintain and replace after long-term use. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where lead screws are difficult to maintain and replace after prolonged use, and to propose a single-wire shaping machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a monofilament setting machine, including a frame, an end cap for closing the top opening of the frame, and a plurality of heating units located inside the frame via a pair of guide rods, the heating units being used for heating and setting monofilaments;

[0008] The heating unit includes a mounting frame, which is fixed to the guide rod by a locking assembly. A heating element and a guide assembly are located at the bottom of the mounting frame. The guide assembly is used to adjust the height between the monofilament and the heating element.

[0009] Furthermore, the locking assembly includes a connecting portion, and at least one pair of the connecting portions are fixedly connected to the top two sides of the mounting bracket. The top of the connecting portion is slidably connected to an abutment portion through a groove, and protrusions are formed on both sides of the connecting portion extending outward. An eccentric rotating abutment member is located inside the protrusion.

[0010] Furthermore, the clamping member is provided with an abutting slope and a yielding slope. The abutting slope is located on the side away from the eccentric shaft. The abutting slope abuts against the abutting part and also abuts against the guide rod through the abutting part. The yielding slope is located close to the eccentric shaft and is used to avoid the abutting part.

[0011] Furthermore, the guiding assembly includes a guide roller, and the bottom of the mounting frame is fixedly connected to support frames on both sides of the heating element. A support rod is provided between the support frames on both sides through a straight groove, and the guide roller is rotatably connected to the periphery of the support rod.

[0012] Furthermore, it also includes a movable component, wherein the support frame extends outward on both sides of the straight groove to form a sliding groove, and the movable component is slidably connected to the sliding groove by a compression spring, wherein the shaft end of the support rod is fixedly connected to the movable component.

[0013] Furthermore, an adjusting member is threadedly connected to the bottom of the support frame, and the adjusting member abuts against the movable member.

[0014] The monofilament setting machine proposed in this utility model has the following advantages: This utility model drives the abutment to contact the guide rod by rotating the abutment, thereby fixing the mounting frame. Furthermore, the position of the mounting frame can be quickly adjusted and fixed by the abutment contacting the guide rod. In addition, a heating element and a guide roller are provided at the bottom of the mounting frame. By rotating the adjusting element, the height of the guide roller can be adjusted in conjunction with the compression spring. Then, by the guide roller contacting and rotating with the monofilament, it can adapt to monofilaments of different diameters, avoiding the situation where the position of the monofilament and the heating element cannot be adjusted, which would cause overheating or poor heating of the monofilament. The structure is simple and highly practical. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1-5 A monofilament setting machine includes a frame 1, an end cap 2 for closing the top opening is provided on the top of the frame 1, and a plurality of heating units 4 are provided inside the frame 1 via a pair of guide rods 3, the heating units 4 being used for heating and setting monofilaments;

[0023] The heating unit 4 includes a mounting frame 41, which is fixed to the guide rod 3 by a locking assembly 5. A heating element 42 and a guide assembly 6 are provided at the bottom of the mounting frame 41. The guide assembly 6 is used to adjust the height between the monofilament and the heating element 42.

[0024] Furthermore, the locking assembly 5 includes a connecting part 51, and at least one pair of the connecting parts 51 are fixedly connected to the top two sides of the mounting bracket 41. The top of the connecting part 51 is slidably connected to an abutment part 52 through a groove. Protrusions 53 extend outward from both sides of the connecting part 51, and an eccentric rotating abutment 54 is located inside the protrusion 53.

[0025] It is worth mentioning that the abutting part 52 is movably connected to the connecting part 51 and is disposed between the clamping member 54 and the guide rod 3. Furthermore, because the abutting part 52 abuts against the guide rod 3 and the clamping member 54 on both sides, it is limited within the connecting part 51.

[0026] Furthermore, the clamping member 54 is provided with an abutting slope 541 and a yielding slope 542. The abutting slope 541 is located on the side away from the eccentric shaft. The abutting slope 541 abuts against the abutting part 52 and also abuts against the guide rod 3 through the abutting part 52. The yielding slope 542 is located close to the eccentric shaft and is used to avoid the abutting part 52.

[0027] In specific operation, the clamping member 54 and the protrusion 53 rotate eccentrically, and the contact slope 541 is set away from the eccentric axis. Therefore, when the clamping member 54 is rotated, the contact slope 541 is pressed against the abutting part 52 due to the eccentricity, and the abutting part 52 is driven and then presses against the guide rod 3.

[0028] Of course, when unlocking the clamping member 54, the guide rod 3 can be unlocked by making way for the inclined surface 542 to avoid the clamping member 54.

[0029] More specifically, the guide assembly 6 includes a guide roller 61, and the bottom of the mounting frame 41 is fixedly connected to the support frame 62 on both sides of the heating element 42. A support rod 63 is provided between the support frames 62 on both sides through a straight groove 621, and the guide roller 61 is rotatably connected to the periphery of the support rod 63.

[0030] In some embodiments, the heating element 42 may be a heating wire or a heating tube. The single wire abuts against and slides against the guide roller 61, and the single wire can be heated and shaped by heating the single wire.

[0031] By adjusting the height of the guide roller 61, it can accommodate monofilaments of different diameters, thus avoiding overheating or poor heating of the monofilaments caused by the inability to adjust the position between the monofilaments and the heating element 42.

[0032] In general, it also includes a movable part 64. The support frame 62 extends outward on both sides of the straight groove 621 to form a sliding groove 622. The movable part 64 is slidably connected to the sliding groove 622 by a compression spring 65. The shaft end of the support rod 63 is fixedly connected to the movable part 64.

[0033] It is worth mentioning that the two ends of the compression spring 65 are fixedly connected to the straight groove 621 and the side of the movable part 64, respectively, and the end of the support rod 63 is also slidably connected to the straight groove 621.

[0034] Finally, an adjusting member 66 is threadedly connected to the bottom of the support frame 62, and the adjusting member 66 abuts against the movable member 64.

[0035] The adjusting member 66 is a screw with a handle. The free end of the screw is threaded to the support frame 62 and abuts against the movable member 64. The movable member 64 drives the guide roller 61 to rise or fall under the action of the compression spring 65 and the adjusting member 66.

[0036] Working method: During operation, the mounting bracket 41 is slidably connected to the guide rod 3. After adjusting the position of the mounting bracket 41, the clamping member 54 is rotated to drive the abutment part 52 to move. The abutment part 52 is driven and abuts against the guide rod 3 to fix the position of the mounting bracket 41. Because the abutting inclined surface 541 abuts against the abutment part 52, the clamping member 54 will not rotate freely.

[0037] When the height of the guide roller 61 needs to be adjusted, the adjusting component 66 is rotated to drive the movable component 64 to rise. The movable component 64 drives the guide roller 61 to rise along the slide groove 622. Alternatively, the adjusting component 66 is rotated to move it down. After the movable component 64 loses its resistance, it drives the guide roller 61 to fall under the action of the compression spring 65, thereby adapting to monofilaments of different diameters and ensuring good heating of the monofilaments.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
