Description

Technical Field

[0001] This utility model relates to the technical field of polyurethane product processing, and in particular to a polyurethane correction device. Background Technology

[0002] Polyurethane materials are widely used in the manufacture of products such as shoe soles, industrial tires, rollers, and sealing rings due to their excellent wear resistance, elasticity, and tear resistance.

[0003] Existing polyurethane correction devices, such as the powerful centering correction device disclosed in utility model patent application number 202421707643.5, mainly include a base box and two C-shaped frames. The C-shaped frames are located at the front and rear ends of the top of the base box, and an adjustment component is installed inside the base box. In use, the distance between the two C-shaped frames is adjusted, and when the push plate and the driven push plate move, they slide on the first guide rod and the second guide rod respectively to support and guide them.

[0004] However, most existing correction devices operate intermittently, requiring manual loading and unloading, resulting in low overall production efficiency. Moreover, their correction methods are limited, with most devices applying correction force only from the sides or a single direction of the product. For products with large flat surfaces or complex curved surfaces, the lack of effective and uniform pressing constraints on the top makes them prone to new secondary deformations such as upward arching or local twisting under the pressure from both sides. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a polyurethane correction device that not only facilitates the forward conveying of products and the continuous correction processing of products, thus improving work efficiency, but also allows for simultaneous correction of both sides of the product and applies pressure to the top of the product to prevent the product from arching upwards or twisting locally.

[0006] This utility model discloses a polyurethane correction device, including a conveying mechanism; it also includes two sets of guiding mechanisms, a driving mechanism, a correction mechanism, a rotating mechanism, and multiple sets of pressing mechanisms. The two sets of guiding mechanisms are installed on the conveying mechanism and guide the product. The driving mechanism is installed on the conveying mechanism and drives the two sets of correction mechanisms to move closer together. Both sets of correction mechanisms are installed on the driving mechanism and correct the product. The rotating mechanism is installed on the conveying mechanism and drives the multiple sets of pressing mechanisms to rotate. The multiple sets of pressing mechanisms are installed on the rotating mechanism and press the product. The conveying mechanism drives the product forward, the two sets of guiding mechanisms cooperate to guide the product, the driving mechanism drives the two sets of correction mechanisms to move closer together to correct the product, and the rotating mechanism drives the multiple sets of pressing mechanisms to rotate and press the top of the product to prevent the product from arching upwards or twisting locally.

[0007] Preferably, the conveying mechanism includes a workbench, a controller, a conveyor belt, and a support platform. The bottom of the workbench is placed on the working surface, the controller is installed on the workbench, the conveyor belt is installed on the workbench, and the support platform is installed on the workbench. The operator controls the conveyor belt to move the polyurethane product forward by controlling the controller. By setting up the support platform, the conveyor belt is prevented from deforming and collapsing when multiple pressing mechanisms press the product, thus ensuring the support effect on the polyurethane product.

[0008] Preferably, the guiding mechanism includes a side baffle, two sets of hydraulic cylinders, and a guide block. The side baffle is installed on the workbench, and both sets of hydraulic cylinders are installed on the side baffle. Synchronization valves are installed on the oil lines of the two sets of hydraulic cylinders. The guide block is connected to the top of the two sets of hydraulic cylinders. The two guiding mechanisms are installed on the left and right sides of the conveyor belt, respectively. The controller controls the start of the two sets of hydraulic cylinders, and the hydraulic cylinders push the guide block to guide the polyurethane product, so that the polyurethane product is positioned in the middle of the conveyor belt, which facilitates subsequent correction.

[0009] Preferably, the drive mechanism includes a first motor, a first reducer, a double-acting lead screw, and two sets of sliders. The first motor is mounted on the worktable, and the power output end of the first motor is connected to the power input end of the first reducer. The power output end of the first reducer is connected to the power input end of the double-acting lead screw. A groove is provided on the worktable, and both sets of sliders are slidably mounted in the groove of the worktable and connected to the double-acting lead screw through threaded transmission. When the first motor is started, the first motor drives the double-acting lead screw to rotate through the first reducer. The double-acting lead screw drives the two sets of sliders to move closer, and the two sets of sliders drive the two sets of correction mechanisms to move closer to perform correction treatment on the polyurethane product.

[0010] Preferably, the correction mechanism includes a top plate, two sets of ribs, multiple sets of guide posts, multiple sets of first springs, multiple sets of positioning sliders, and multiple sets of correction wheels. The top plate is mounted on the sliders, and the two sets of ribs are connected and mounted between the sliders and the top plate. The top plate has multiple sets of positioning grooves, and the multiple sets of guide posts are respectively installed in the multiple sets of positioning grooves. The multiple sets of first springs are respectively fitted on the multiple sets of guide posts, and the multiple sets of positioning sliders are respectively slidably mounted on the multiple sets of guide posts. The multiple sets of correction wheels are respectively rotatably mounted on the multiple sets of positioning sliders. The sliders drive the top plate closer to the polyurethane product. The two sets of ribs ensure the support force on the top plate, and the multiple sets of correction wheels squeeze and correct the polyurethane product.

The second spring is conveniently designed to accommodate polyurethane products of different widths, and the pressing mechanisms on both sides can remain above the correction mechanism.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the conveying mechanism drives the product forward, two sets of guiding mechanisms cooperate to guide the product, the driving mechanism drives two sets of correcting mechanisms to approach and correct the product, and the rotating mechanism drives multiple sets of pressing mechanisms to rotate and press the top of the product, so as to prevent the product from arching upward or twisting locally.

To achieve the desired support effect, controller 12 activates two sets of hydraulic cylinders 22. These cylinders push guide blocks 23 to guide the polyurethane product, positioning it in the middle of the conveyor belt 13 for easier subsequent correction. The first motor 31 is then activated, driving a bidirectional lead screw 33 via a first reducer 32. This lead screw 33 moves two sets of sliders 34 closer together, which in turn move the top plate 41 closer to the polyurethane product. Two sets of ribs 42 ensure support for the top plate 41.
