Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically a high-efficiency torsion bar production device. Background Technology

[0002] Pipe cleaners, also known as wire rods, are a type of craft material made by wrapping wire with yarn. They are widely used in children's crafts and various creative decorations due to their good shapeability and rich colors. The production process mainly involves evenly winding the yarn around the wire and then twisting and fixing it into shape. However, existing pipe cleaner production equipment has many shortcomings.

[0003] First, traditional equipment mostly uses a single-sided stretching method. After each stretching is completed, it needs to travel empty back to the starting point to perform the next stretching, which wastes a lot of time and reduces production efficiency. Second, the existing equipment has a low degree of automation and still requires a lot of manual intervention in many aspects, which not only increases labor costs but also limits the improvement of production efficiency.

Figure 1 The directions or positional relationships shown are for the purpose of describing this utility model only, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] In the description of this application, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0020] To solve the above technical problems, such as Figure 1-3 As shown, this utility model designs a high-efficiency pipe cleaner production device, including a feeding assembly mechanism 1, which is used to wind yarn onto iron wire. It also includes a frame 2, a linear drive assembly 3, and a traction and stretching mechanism 4. The linear drive assembly 3 is mounted on the frame 2 and connected to the traction and stretching mechanism 4. The linear drive assembly 3 drives the traction and stretching mechanism 4 to move back and forth along a straight line. Two sets of feeding assembly mechanisms 1 are symmetrically arranged on the front and rear sides of the frame 2. The traction and stretching mechanism 4 includes two sets of rotating clamping assemblies symmetrically arranged on the front and rear sides. The rotating clamping assemblies are used to rotate and stretch the iron wire with the yarn wound on it, output from the feeding assembly mechanism 1. Through the double-sided stretching design, combined with the linear drive assembly 3 and the traction and stretching mechanism 4, each round trip can stretch the iron wire on both sides sequentially, eliminating the idle stroke of the single-sided stretching equipment and significantly improving production efficiency.

[0021] In this embodiment, it is further preferred that the traction and stretching mechanism 4 also includes a base 41, and the linear drive assembly 3 includes a linear guide rail 31, a rack 32, a gear 33, and a drive motor 34. Each base 41 has several sliders symmetrically arranged on the left and right sides below it. The two sets of linear guide rails 31 are symmetrically arranged on the frame 2. The sliders 35 are slidably engaged with the linear guide rails 31. The drive motor 34 is fixedly installed on the base 41 and its output shaft faces downward and is connected to the gear 33. The rack 32 is installed on the frame 2 and is arranged parallel to the linear guide rails 31. The rack 32 meshes with the gear 33. The drive motor 34 is used to drive the gear 33 to rotate so that the base 41 can slide along the direction of the linear guide rail 31. By driving the gear 33 to rotate through the drive motor 34, the base 41 slides along the linear guide rail 31, which not only ensures the stability and accuracy of the movement of the traction and stretching mechanism 4, but also realizes efficient linear motion, effectively improving production efficiency. At the same time, it ensures the uniformity and consistency of wire stretching, thereby improving the forming quality of the twisted rod.

[0022] In this embodiment, it is further preferred that the traction and stretching mechanism 4 also includes support columns 42 and support plates 43. The two sets of support columns 42 are symmetrically arranged front and rear. The top of each set of support columns 42 is connected to a support plate 43. The support plate 43 is used to connect with the rotating clamping assembly. The structural design of the support columns 42 and support plates 43 provides a stable support and installation foundation for the rotating clamping assembly, ensuring its stability and reliability when rotating and stretching the wire, and enhancing the structural strength and operational stability of the entire device.

[0023] In this embodiment, it is further preferred that the traction and tensioning mechanism 4 also includes a lifting assembly, which includes a rodless slide cylinder 44, a lifting plate 45, and a transverse mounting plate 46. The rodless slide cylinder 44 is installed on one side of the support column 42 and is set perpendicular to the horizontal plane. The slide of the rodless slide cylinder 44 is fixedly connected to the lifting plate 45, and the transverse mounting plate 46 is fixedly connected to the lifting plate 45. This realizes the height adjustability of the rotating clamping assembly, which can flexibly adjust the operating height according to different production needs, and enhances the versatility and adaptability of the equipment.

[0024] In a further preferred embodiment, the rotary clamping assembly further includes pneumatic grippers 47, a linear cylinder 48, a push plate 49, a support shaft 410, a slide 411, and a spring 412. A plurality of pneumatic grippers 47 are spaced apart below the transverse mounting plate 46. A plurality of support shafts 410 correspond to the pneumatic grippers 47. One end of each support shaft 410 passes through the support plate 43, and the other end is used to connect with a rotary motor (not shown in the figure). The support shaft 410 can rotate under its drive. The support shaft 410 has an inclined through hole 413 for the product to pass through. The support shaft 410 is provided with... A sliding slide 411 is provided, and a spring 412 is connected to the slide 411. A linear cylinder 48 is installed on one side of a support plate 43. The piston rod of the linear cylinder 48 passes through the support plate 43 and is connected to a push plate 49. Each push plate 49 has two grooves, and the support shaft 410 passes through the grooves. Before stretching, one end of the product is partially passed through the through hole 413. The linear cylinder 48 achieves rapid and precise motion control, causing the push plate 49 to press forward. Thus, the push plate 49 can drive the slide 411 to move and press the end of the product. Then, during stretching, the support shaft 410 starts to rotate, which allows for twisting. A pneumatic gripper 47 assists in providing stable clamping force.

[0025] In this embodiment, a further preferred embodiment includes a cutting mechanism 5 on the frame 2. The cutting mechanism 5 includes a lifting cylinder 51, pneumatic shears 52, guide rods 53, guide sleeves 54, and a lifting plate 55. The cylinder body of the lifting cylinder 51 is fixedly connected to the frame 2, and the piston rod of the lifting cylinder 51 faces upward and is connected to the lifting plate 55. Several pneumatic shears 52 are installed on the lifting plate 55. The pneumatic shears 52 are used to cut the wire that has completed traction and stretching. Two guide rods 53 are symmetrically arranged on both sides of the lifting cylinder 51. The lifting plate 55 is fixedly connected to the guide sleeve 54, and the guide sleeve 54 slides with the guide rods 53. The lifting cylinder 51 drives the lifting plate 55 and the pneumatic shears 52 to move up and down. The guide rods 53 and guide sleeves 54 ensure the smoothness and accuracy of the operation, realizing the automatic and precise cutting of the wire that has completed traction and stretching, improving production efficiency and product quality, reducing manual intervention, and lowering labor costs.
