Description

Technical Field

[0001] This utility model belongs to the field of polyurethane foam cutting, and specifically relates to an auxiliary positioning mechanism for polyurethane foam cutting. Background Technology

[0002] Polyurethane foam is soft and has good elasticity and compressibility. During the cutting process, the foam is easily deformed by the pressure of the cutting tool, and after being cut, the foam may regain some of its thickness due to its resilience, thus interfering with and affecting the flatness of the cut.

[0003] Meanwhile, due to the uneven compression ratio, density, and thickness of polyurethane foam, these characteristics make it difficult to maintain a consistent cutting depth during the cutting process. Furthermore, polyurethane foam is prone to generating static electricity due to friction, which further affects the accuracy and smoothness of the cutting process.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide an auxiliary positioning mechanism for cutting polyurethane foam. Through the cooperation of several positioning components, the auxiliary positioning function for cutting polyurethane foam is realized. At the same time, by setting the antistatic bar component, the problem of static electricity generated by friction in polyurethane foam is solved, which greatly improves the efficiency and accuracy of cutting.

[0006] Technical Solution: To achieve the above objectives, this utility model provides an auxiliary positioning mechanism for cutting polyurethane foam, including a placement frame, a middle positioning component, a front guide positioning component, a rear guide positioning component, and an antistatic bar assembly; the middle positioning component is disposed on the placement frame; the front guide positioning component and the rear guide positioning component are both disposed on the placement frame and located on both sides of the middle positioning component; the rear guide positioning component includes a rear active rotating shaft, a rear driven rotating shaft, and a transmission component; the rear active rotating shaft is disposed between the placement frames and located beside the middle positioning component; the rear driven rotating shaft is disposed between the placement frames and located above the rear active rotating shaft; the transmission component is disposed beside the placement frame and connects the rear active rotating shaft and the middle positioning component to achieve transmission; an antistatic bar assembly is provided on the side of the rear guide positioning component away from the middle positioning component.

[0007] Furthermore, the material to be cut sequentially passes through the front guide positioning component, the middle positioning component, and the rear guide positioning component to complete its positioning. Static electricity that may exist during the cutting process is removed by the anti-static bar component. The cutting operation is performed on the side of the anti-static bar component away from the rear guide positioning component. Through the cooperation of several positioning components, an auxiliary positioning function for cutting polyurethane foam is achieved. Simultaneously, it integrates multiple functions such as positioning, transmission, and static electricity elimination, greatly improving the efficiency and accuracy of cutting.

[0008] Furthermore, the central positioning assembly includes a support plate, a central active rotating shaft, a central driven rotating shaft, and several limiting rods. The support plate is disposed between the placement frames. The central active rotating shaft is located on one side of the support plate near the rear guide positioning assembly. The central driven rotating shaft is located on one side of the support plate near the front guide positioning assembly. The limiting rods are disposed between the placement frames and above the support plate. The support plate, located between the placement frames, provides a stable support platform for the central positioning assembly, ensuring the stable placement of the material to be cut. The limiting rods, located above the support plate, effectively limit the displacement range of the material to be cut, preventing accidental movement or deviation during the positioning process, thereby improving the accuracy and reliability of the positioning.

[0009] Furthermore, the transmission components include a rear motor, three transmission gears, and a transmission belt; the rear motor is located beside the placement frame; transmission gears are provided at one end of the rear drive shaft and the middle drive shaft on the same side, as well as at the output end of the rear motor; the three transmission gears are connected by a transmission belt. The combination of transmission gears and transmission belts combines the high precision of gear transmission with the buffering characteristics of belt transmission. Belt transmission effectively reduces impact and vibration during transmission, thereby reducing noise, making the machine run more smoothly, and ensuring the readiness of auxiliary positioning.

[0010] Furthermore, the front guiding and positioning assembly includes a front active rotating shaft, a front driven rotating shaft, and a front motor. The front active rotating shaft is located between the placement frames and on the side of the middle positioning assembly away from the rear guiding and positioning assembly. The front driven rotating shaft is located between the placement frames and above the front active rotating shaft. The front motor is located on one side of the placement frame, and its output end is connected to one end of the front active rotating shaft. Through the coordinated action of the front active rotating shaft and the front driven rotating shaft, the front guiding and positioning assembly provides stable and precise guidance for the material, ensuring that the material moves along a predetermined path, effectively limiting vibration and offset of the material during movement, and improving the accuracy of cutting and positioning.

[0011] Furthermore, the antistatic bar assembly includes a set of clamps, a set of connectors, and an antistatic air bar; the clamps are mounted on the placement frame via the connectors; the antistatic air bar is positioned between the clamps and located beside the rear active rotating shaft. The antistatic air bar generates a large number of air masses carrying both positive and negative charges, which can quickly neutralize static electricity on the material surface, ensuring the stability of the cutting process.

[0012] Furthermore, both the front driven shaft and the rear driven shaft have several textured surfaces. These textures significantly increase the friction between the shaft and the material to be cut, thereby preventing slippage or accidental rotation and improving the stability and reliability of the cutting process.

[0013] Furthermore, the placement rack is equipped with dustproof housings on both sides. These dustproof housings prevent equipment malfunctions caused by dust accumulation, ensuring the stability of the equipment during long-term use.

[0014] As can be seen from the above technical solution, this utility model has the following beneficial effects:

The cutting operation is carried out on the side of the antistatic rod component 5 away from the rear guide positioning component 4.

[0030] In particular, it is preferable to add a spring clamping mechanism to the central positioning component 2 to enhance the stability of the polyurethane foam during positioning, while avoiding damage to the foam.
