Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic processing material drying box, specifically to a material drying box for plastic processing. BACKGROUND

[0002] In the plastic processing industry, the material drying box as one of the key equipment is widely used in the preheating and drying process of raw materials such as plastic particles and fragments to ensure the stability and uniformity of the plastic raw materials in the subsequent processing. The existing material drying box design usually includes a heating cavity, which is provided with heating elements inside to raise the internal temperature, and a specific ventilation system is used to maintain air circulation inside the cavity to achieve efficient heating and drying effect.

[0003] In order to conveniently send a large amount of plastic raw materials into the material drying box for heating treatment, most material drying boxes are equipped with material cart systems. These material carts are designed with specific chute interfaces that can slide into the heating cavity from the outside of the material drying box. However, in actual operation, this process often relies on manual pushing of the material cart.

[0004] Since the material cart usually carries heavy plastic raw materials and needs to be accurately aligned with the chute inlet of the material drying box in a limited space, manual operation often faces great challenges. Due to factors such as line of sight, operating space or operating proficiency, the material cart can easily lose control during the pushing process, resulting in collision with the inner wall of the material drying box. Such collision not only damages the structure of the material drying box, affecting its sealing and heating efficiency, but also easily causes damage to the material cart and the raw materials it carries, increasing production costs and safety risks.

[0026] A kind of drying material box for plastic processing, including drying material box main body 1, box door 2 is movably installed in one side of drying material box main body 1, and two groups of chutes 3 are set in the inner wall bottom side of drying material box main body 1, two groups of buffer mechanism are fixedly installed in the inner wall rear side of drying material box main body 1, two groups of buffer mechanism include fixed plate 511, and multiple groups of link plate 512 are fixedly installed in the two sides of fixed plate 511, multiple groups of link plate 512 are all fixedly connected with the inner wall of drying material box main body 1 by screw 513, multiple groups of round plate 412 are fixedly installed on the outer surface of one side of fixed plate 511, and another group of round plate 412 is installed on the side of multiple groups of round plate 412, and another group of round plate 412 is connected with damping plate 5 on one side, and spring 411 is also connected between round plate 412.

[0027] Further, the outer surface of damping plate 5 is wrapped with rubber, and the outer surface of damping plate 5 is circular arc, the elasticity of rubber and the design of circular arc can better disperse and absorb impact force, protect drying material box and material cart from being damaged.

[0028] Further, two groups of guide triangular blocks 4 are fixedly installed at the bottom end of drying material box main body 1, and two groups of guide triangular blocks 4 are beneficial to the movement of material cart.

[0029] Further, the top end of the baking box body 1 is fixedly installed with a plurality of support rods 6, the top end of the plurality of support rods 6 is fixedly installed with a top plate 7, the middle end of the top plate 7 is fixedly installed with a gas cylinder 8, the bottom end of the gas cylinder 8 is connected with a connecting rod 811, the surface of the connecting rod 811 is connected with a clamping plate 711, the outer surface of the clamping plate 711 is wrapped with rubber, the clamping plate 711 is driven to descend and clamp the material cart by the gas cylinder 8, so as to ensure the stability during use and prevent accidents caused by shaking or tilting.

[0030] Further, the outer surface of the top plate 7 is fixedly installed with a plurality of sleeves 9, the inner wall of the plurality of sleeves 9 is movably installed with a limiting rod 911, one end of the limiting rod 911 is connected with the clamping plate 711 through the top end of the baking box body 1, and the combination of the plurality of sleeves 9 and the limiting rod 911 provides stable guidance for the movement of the clamping plate.

[0031] Further, the top end of the plurality of limiting rods 911 is fixedly installed with a limiting plate 912, the limiting plate 912 limits the movement of the limiting rod 911, and prevents the limiting rod 911 from being pulled out of the sleeve 9.

[0032] Further, one end of the plurality of connecting plates 512 is arc-shaped, which helps to reduce sharp corners generated during assembly or maintenance, and improves the safety of the operator.

[0033] Working principle: in the plastic processing process, when the material cart needs to be sent into the material drying box for heating treatment, first, the material cart stably approaches the material drying box body 1 along the guide direction of the two sets of guide triangular blocks 4, and with the further advancement of the material cart, it enters the two sets of sliding grooves 3 opened on the inner wall of the material drying box body 1. The design of the sliding groove 3 provides a stable travel path for the material cart, ensuring the stability of the cart during advancement. However, due to the uncertainty in the operation process, the material cart may still collide slightly with the inner wall of the material drying box. At this time, the buffer mechanism installed at the rear side of the inner wall of the material drying box body 1 plays a key role. When the material cart contacts the outer surface of the damping plate 5, the outer surface of the damping plate 5 has good elasticity and buffering performance, which can first absorb part of the impact force and reduce the impact degree of the collision. At the same time, the combined action of the damper 413 and the spring 411 enhances the buffering effect. The damper 413 consumes the energy generated by the collision, and the spring 411 absorbs and stores energy through its elastic deformation. The two work together to significantly reduce the damage caused by the collision to the material drying box and the material cart. After the material cart is completely pushed into the material drying box, in order to further ensure its stability, the driving cylinder 8 can be used. After receiving the control signal, the cylinder 8 drives the connecting rod 811 to descend through the extension and retraction movement of its piston rod. The downward movement of the connecting rod 811 in turn drives the clamping plate 711 to move downward until the clamping plate 711 abuts against the outer surface of the material cart. Since the outer surface of the clamping plate 711 is also wrapped with rubber, it not only increases the stability of clamping, but also avoids additional damage to the material cart caused by the clamping plate.

[0034] It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.
