Description

TECHNICAL FIELD

[0001] The utility model relates to a shavings board production equipment technical field, concretely relates to a shavings board screen ring type polisher blade. BACKGROUND

[0002] The screen ring type polisher is mainly used for the material preparation section of the shavings board production line, and its core function is to grind the coarse shavings into the fine shavings required for the surface layer. The existing screen ring type polisher blade is prone to wear and dullness, so the convenient replacement of the blade is crucial to the maintenance efficiency of the equipment. However, the traditional blade is fixed by welding, which requires the replacement of the entire mold when a single piece is damaged, resulting in resource waste.

[0003] Therefore, the patent with the publication number CN211517188U proposes a screen ring type polisher blade that uses a spring type disassembly mechanism to achieve quick disassembly of the blade through the cooperation of a buckle and a spring. However, the disassembly mechanism relies on multiple springs under pressure to maintain the clamping state, which can easily cause spring fatigue in a continuous working environment. Since the spring material is usually high-hardness tungsten steel, it has wear-resistant properties, but its elastic modulus is low and its brittleness is high, which can easily cause plastic deformation or fracture during repeated compression, leading to loss of elasticity. In addition, the spring layout of this patent has a stress concentration problem, such as the parallel design of multiple springs, which exacerbates local load and accelerates the fatigue process. After the loss of elasticity, the stability of the buckle and the slot decreases, resulting in increased disassembly resistance or accidental buckle release, which affects the replacement efficiency and increases the safety hazard. At the same time, frequent replacement of the spring assembly increases maintenance costs, which weakens the practical advantages of the disassembly mechanism.

[0004] In summary, the spring type disassembly mechanism of the above-mentioned screen ring type polisher blade is limited by material properties and structural design, making it difficult to balance durability and reliability, and improvement is urgently needed to solve the problem of disassembly function degradation caused by spring fatigue.

The limiting piece is detachably connected to the fixed block by a screw. Tightening the screw can make the limiting piece vertically abut the side surface of the blade body.

[0020] Hereinafter, only certain exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the following description is considered to be essentially exemplary rather than limiting.

[0021] Please refer to Figure 1 And Figure 2 In one embodiment of the particle board screen ring type sander blade of the present application, the particle board screen ring type sander blade comprises a cutter body 1 and a limiting piece 2; wherein the two side surfaces of the cutter body 1 are inclined surfaces, and a cuboid-shaped positioning block 11 is welded to the middle of the bottom surface of the cutter body 1, which can be embedded in the end of the sander blade 5; two fixed blocks 3 are respectively fixed to the outer sides of the two inclined surfaces, and the two fixed blocks 3 can be welded to the end surface of the sander blade 5; the limiting piece 2 is detachably connected to the fixed blocks 3 by screws 4, and tightening the screws 4 can make the limiting piece 2 perpendicularly abut against the side surface of the cutter body 1, thereby pressing the cutter body 1 tightly against the end of the blade 5, and cooperating with the positioning effect of the positioning block 11, the movement of the cutter body 1 can be effectively limited; loosening the screws 4 can make the limiting piece 2 disengage from the side surface of the cutter body 1, so that the cutter body 1 loses the force of the limiting piece 2 and can be detached from the blade 5.

[0022] As a preferred embodiment, the cross section of the cutter body 1 is an isosceles triangle, so that when the tip of the cutter body 1 bears external force, the force can be effectively transmitted and dispersed along the sides and angles, improving stability.

[0023] As a preferred embodiment, the fixed blocks 3 are inclined, and the inclination angles are the same as the side surface of the cutter body 1, both being 60 degrees; the design of the same inclination angles of the two makes the contact surface between the limiting piece 2 and the side surface of the cutter body 1 larger when the limiting piece 2 perpendicularly abuts against the side surface of the cutter body 1, and the force on the cutter body 1 is more stable, thereby improving the fixing effect.

[0024] In a specific embodiment, the limiting piece 2 is inverted U-shaped, and the inclination direction of the limiting piece 2 is the same as that of the fixed blocks 3; the inverted U-shaped limiting piece 2 is sleeved on the fixed blocks 3, and the screws 4 penetrate the ends of the limiting piece 2 away from the cutter body 1 and are perpendicularly screwed to the fixed blocks 3; in this way, when the screws 4 are tightened, the nuts of the screws 4 can push the limiting piece 2, so that the limiting piece 2 perpendicularly abuts against the side surface of the cutter body 1.

[0025] As a preferred embodiment, two fixed blocks 3 and limiting pieces 2 are arranged on each side surface of the cutter body 1, so that the cutter body 1 can be fixed at two points, thereby better combining into an integral structure and making the entire blade more stable.

[0026] On this basis, the limiting plate 21 can be integrally connected at one end of the limiting member 2 close to the cutter body 1, the limiting plate 21 is spaced apart from the lower edge of the cutter body 1, avoiding the limiting member 2 abutting against the side surface of the cutter body 1 before the limiting plate 21 contacts the blade 5 and hindering the movement of the limiting member 2; the limiting plate 21 is tightly attached to the end surface of the cutter body 1, so that the cutter body 1 is limited to move axially by the limiting plates 21 at both ends, thereby further improving the fixing effect.

[0027] The use method or working principle of the utility model is as follows:

[0028] The screening ring type polisher drives the shavings to the inner wall of the grinding screening ring by high-speed rotating the blade 5, and cooperates with the cutter body 1 to polish, when the cutter body 1 is worn during the polishing process, first stop rotating the blade 5, then loosen the screw 4 to make the limiting member 2 lose the limitation of the screw cap of the screw 4, then move the limiting member 2 outward to disengage from the side surface of the cutter body 1, so that the cutter body 1 loses the force of the limiting member 2, thereby the cutter body 1 can be disassembled from the blade 5; after disassembling the worn cutter body 1, place the new cutter body 1 on the end surface of the blade 5 and the positioning block 11 is embedded in the end portion of the blade 5, then tighten the screw 4 to push the limiting member 2 through the screw cap of the screw 4, so that the limiting member 2 vertically abuts against the side surface of the cutter body 1, since the side surface of the cutter body 1 is inclined, the limiting member 2 can press the cutter body 1 tightly on the end portion of the blade 5, cooperating with the positioning effect of the positioning block 11, the movement of the cutter body 1 can be effectively limited.

[0029] The above is only the preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
