Description

Technical Field

[0001] This utility model relates to the field of paper product processing equipment technology, and in particular to an arc-shaped groove folding roller forming device. Background Technology

[0002] Arc-groove folding roller forming device is a commonly used equipment in the paper product processing field. It mainly uses a roller with a specific groove shape to roll and press sheet materials such as paper, thereby forming a preset crease or shape on the surface of the material to achieve automated forming processing.

[0003] In existing technologies, the forming rollers are usually firmly fixed to the equipment frame by bearing seats at both ends. When different specifications of forming rollers need to be changed according to different production needs, operators must first disassemble the complex bearing seat fasteners, and sometimes disconnect the coupling with the drive motor. The whole process is not only cumbersome and time-consuming, but also labor-intensive. This structure leads to excessive downtime when the equipment switches production tasks, which seriously affects production efficiency and adaptability to small batch and multi-specification orders.

[0004] In addition, existing roller forming devices also have shortcomings in the material conveying process. Most devices rely on simple conveying rollers for material transfer and lack guiding mechanisms to effectively smooth the material and accurately limit its lateral movement. When sheet materials are conveyed, especially at high speeds, they are prone to wrinkling or lateral deviation due to airflow disturbances or uneven tension, i.e., "deviation". This instability in the conveying process directly leads to inaccurate positioning of the material entering the forming roller, resulting in quality problems such as skewed creases and dimensional deviations in the final product, increasing the product defect rate.

[0005] Therefore, this utility model proposes an arc-shaped groove folding roller forming device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the arc-groove folding roller forming device, such as the complicated and time-consuming process of changing the forming roller, low maintenance efficiency, and the easy deviation of materials during the conveying process, which affects the processing quality, this utility model aims to provide an arc-groove folding roller forming device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a forming device for an arc-shaped grooved paper folding roller, comprising: a working platform, a transmission roller disposed on the working platform, and an arc-shaped grooved sleeve fitted on the transmission roller; as well as a loading / unloading mechanism and a guiding mechanism. The loading / unloading mechanism includes a support block fixed to the working platform, a positioning ring connected to the transmission roller, and an electric telescopic rod for lifting the positioning ring. The guiding mechanism includes a rubber roller rotatably connected between two fixed blocks on the working platform, two guide rods slidably connected to the working platform, and a lead screw installed in a fixed box and threadedly connected to the guide rods. Furthermore, the outer wall of the transmission roller has a positioning groove that mates with the positioning block on the inner wall of the arc-shaped grooved sleeve. The motor is fixedly connected to the transmission roller via the positioning ring. The lead screw is connected to a knob, and a limiting block that slides within a limiting groove on the working platform is fixed to the bottom of the guide rod.

[0008] Preferably, the telescopic end of the electric telescopic rod passes through the working platform and is connected to the positioning ring. When the electric telescopic rod extends, it can lift the transmission roller and disengage it from the support block.

[0009] Preferably, the positioning groove on the outer wall of the transmission roller and the positioning block on the inner wall of the arc-shaped groove sleeve are in a snap-fit ​​structure.

[0010] Preferably, the two guide rods are threadedly connected to the lead screw, and rotating the knob can drive the lead screw to rotate, thereby causing the two guide rods to move towards or away from each other along the axial direction of the lead screw.

[0011] Preferably, the limiting block and the limiting groove are in a sliding fit structure to prevent the guide rod from tilting during movement.

[0012] Preferably, the motor is fixed to the rear side of the positioning ring, and the output end of the motor passes through the positioning ring and is fixedly connected to the transmission roller.

[0013] Preferably, the front end of the lead screw extends out of the fixing box and is fixedly connected to the knob.

[0014] Preferably, the rubber roller is made of rubber with a high coefficient of friction and is used to guide, convey, and smooth the material.

[0015] This utility model has the following beneficial effects: 1. This utility model, by setting up an loading and unloading mechanism that cooperates with an electric telescopic rod, a positioning ring and a support block, uses the electric telescopic rod to lift one end of the transmission roller to detach it from the support, creating a convenient operating space for the axial replacement of the arc-shaped groove ring, and solving the problems of complex, time-consuming and inefficient maintenance of the forming roller body replacement process in the prior art.

[0016] 2. This utility model solves the problem in the prior art that the lack of an effective smoothing and guiding mechanism leads to the material easily deviating during the conveying process and affecting the final molding quality. It sets up a guiding mechanism that cooperates with a rubber roller and an adjustable spacing guide rod driven by a screw, and uses the sliding cooperation between the limiting block and the limiting groove to ensure the movement stability of the guide rod.

[0021] Please refer to Figure 3 An electric telescopic rod 26 is fixedly installed at the bottom of the work platform 1. The telescopic end of the electric telescopic rod 26 passes through the work platform 1 and is fixedly connected to the positioning ring 27.

[0022] Please refer to Figure 4A fixed box 33 is fixedly installed on the right side of the work platform 1. The lead screw 34 is rotatably housed in the fixed box 33.

[0023] As a preferred embodiment, please refer to Figure 3 The telescopic end of the electric telescopic rod 26 passes through the working platform 1 and is fixedly connected to the positioning ring 27.

[0024] As a preferred embodiment, please refer to Figure 3 To achieve stable power transmission, the positioning groove 22 on the outer wall of the transmission roller 21 and the positioning block 24 on the inner wall of the arc-shaped grooved collar 23 are preferably engaged.

[0025] As a preferred embodiment, please refer to Figure 4 To facilitate the adjustment of the spacing between the guide rods 36, the outer side of the lead screw 34 is threadedly connected to the corresponding positions of the two guide rods 36. Rotating the knob 35 can drive the lead screw 34 to rotate, and the two guide rods 36 can be moved towards or away from each other along the axial direction of the lead screw 34 by utilizing the principle of the threaded pair.

[0026] As a preferred embodiment, please refer to Figure 4 To prevent the guide rod 36 from tilting during movement, the limiting block 37 and the limiting groove 38 are in sliding fit to ensure that the guide rod 36 remains straight during adjustment.

[0027] As a preferred embodiment, please refer to Figure 3 To ensure the coaxiality and stability of the power output, the motor 28 is preferably fixed to the rear side of the positioning ring 27, and the output end of the motor 28 passes through the positioning ring 27 and is then fixedly connected to the rear end of the transmission roller 21.

[0028] As a preferred embodiment, please refer to Figure 4 For ease of operation, the front end of the lead screw 34 extends out of the fixing box 33 and is fixedly connected to the knob 35. The fixing box 33 rotatably houses the lead screw 34.

[0029] As a preferred embodiment, please refer to Figure 1 and Figure 4 To achieve material smoothing, the rubber roller 32 is preferably made of rubber with a high coefficient of friction. The friction between the rubber roller 32 and the material placed on the work platform 1 is used to guide, transport and smooth the material.

[0030] Working principle: Before the origami forming process, the guide mechanism 3 is first adjusted according to the width of the material to be processed. The operator rotates the knob 35, which drives the lead screw 34 fixedly connected to it to rotate. Since the lead screw 34 is threadedly connected to the two guide rods 36, and the part of the guide rod 36 in the fixed box 33 is restricted by the fixed box 33, the rotation of the lead screw 34 will drive the two guide rods 36 to move towards or away from each other along the axial direction of the lead screw 34. During the movement of the guide rod 36, the two limiting blocks 37 fixedly connected to its bottom will slide synchronously along the limiting groove 38 on the working platform 1. Through the sliding cooperation between the limiting block 37 and the limiting groove 38, the guide rod 36 is effectively prevented from tilting during the movement and positioning process, ensuring that the two guide rods 36 always remain parallel, thereby enabling reliable guidance of the material. After adjustment, the sheet material is placed on the work platform 1 and fed into the guide mechanism 3. The material first comes into contact with the rubber roller 32 rotatably connected between the two fixed blocks 31. In subsequent processing, the rubber roller 32 smooths the material and transports it in a coordinated manner through the friction between itself and the material. The material passing through the rubber roller 32 then enters between the two guide rods 36 and is laterally limited by the guide rods 36 to ensure that the material can be transported straight and without deviation to the subsequent forming area, thereby ensuring the final processing quality. After the material is precisely guided, it enters the arc-shaped grooved sleeve 23 for roll forming. At this time, the motor 28 fixed on the back of the positioning ring 27 is started. The power of the motor 28 is transmitted to the transmission roller 21 through its output end. Since the positioning groove 22 on the outer wall of the transmission roller 21 is precisely engaged with the positioning block 24 on the inner wall of the arc-shaped grooved sleeve 23, the rotational power of the transmission roller 21 can be stably transmitted to the arc-shaped grooved sleeve 23, avoiding idle rotation or slippage during the transmission process. The arc-shaped grooved sleeve 23 rotates accordingly, and the material conveyed below is continuously rolled through the arc-shaped groove on its surface, thereby folding and forming. When it is necessary to replace the arc-shaped grooved sleeve 23 of different specifications to adapt to different processing requirements, first stop the motor 28, then control the electric telescopic rod 26 fixed at the bottom of the work platform 1 to extend. The telescopic end of the electric telescopic rod 26 pushes the rear end of the transmission roller 21 upward through the positioning ring 27 connected to it, so that the transmission roller 21 tilts with the front support block 25 as the fulcrum. After the front end is disengaged from the support block 25, the operator can easily slide the old arc-shaped grooved sleeve 23 off the transmission roller 21 axially and remove it, then install the new arc-shaped grooved sleeve 23, and finally control the electric telescopic rod 26 to retract, so that the transmission roller 21 returns to the horizontal working state supported by the support block 25 and the positioning ring 27. Through the coordinated action of the loading and unloading mechanism 2, this utility model solves the problem of complex and time-consuming replacement process of molding parts in the prior art, and significantly improves the maintenance efficiency of the equipment and its adaptability to different processing requirements.
