Description

Technical Field

[0001] This utility model relates to the technical field of plywood processing equipment, and in particular to an edge cleaning machine that prevents chipping. Background Technology

[0002] The main function of an edge cleaning machine is to remove the debris generated during the pressing of the veneer onto the particleboard using a cutting blade, ensuring the cleanliness of the board edges and preventing debris from affecting subsequent processes. However, the original structure of existing edge cleaning machines has a significant defect: its spring components are exposed without effective protective measures.

[0003] In actual production, a large amount of debris generated during the pressing process easily falls onto the exposed springs, and may even enter the slider due to vibrations during equipment operation. When debris accumulates between the slider and the slide rod, it can obstruct the transmission between them. The incorporation of a large amount of paper scraps can also cause the cutting blade holder to be firmly clamped, preventing the cutting blade from moving normally and thus losing its ability to clean the edges of the board. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an edge cleaning machine that prevents debris.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A chip-proof edge trimming machine for cutting edges of sheet metal, including

[0007] A cutting base, wherein a sliding rod is movably connected to the cutting base, and a cutting blade is provided on the cutting base for cutting sheet metal;

[0008] The slide bar has fixing members at both ends, and an elastic member is provided between the fixing members and the cutting seat; and

[0009] The protective device includes a protective sleeve disposed between the cutting seat and the fixing member of the slide rod, and surrounding the slide rod and the elastic member. The protective sleeve is kept open by the elastic force of the elastic member to prevent debris from entering.

[0010] Furthermore, the cutting seat includes a slider and a blade fixing plate nested from the inside out, the slider rod passing through the slider, and the slider being slidably connected to the blade fixing plate.

[0011] Furthermore, the outer surface of the slider is provided with several arc-shaped protrusions around its central axis, and the blade fixing plate is provided with guide holes in the axial direction, with the arc-shaped protrusions abutting against the guide holes.

[0012] Furthermore, the length direction of the slide rod is the first direction, the major diameter direction of the guide hole is the second direction, and the first direction is perpendicular to the second direction; when the cutting seat cuts the plate, the blade fixing plate and the slider generate relative displacement, and the blade fixing plate can slide along the first direction and / or the second direction.

[0013] Furthermore, a cutting blade is provided on one side of the blade fixing plate, and the cutting blade is used to cut the plate.

[0014] Furthermore, the protective device includes a protective sleeve, with first retaining sleeves symmetrically arranged at both ends of the blade fixing plate, and second retaining sleeves arranged at both ends of the slide rod, with the protective sleeve located between the first retaining sleeves and the second retaining sleeves.

[0015] Furthermore, the elastic element is provided between the first retaining sleeve and the second retaining sleeve.

[0016] Furthermore, the protective device includes a hose clamp, with both ends of the protective sleeve respectively fitted onto the outer sides of the first and second retaining sleeves and fixed by the hose clamp.

[0017] Furthermore, it also includes a support device, which includes a support rod that passes through the blade fixing plate in a third direction perpendicular to the first direction and the second direction, and the support rod is movable in the second direction.

[0018] Furthermore, the slide rod is provided with nut seats at both ends, and a base plate is provided between the nut seat at one end and the second stop sleeve.

[0019] The beneficial effects of this utility model are:

[0020] 1. The present invention proposes a chip-proof edge cleaning machine, in which a protective device is wrapped to form a closed space, achieving physical isolation of the cavity and completely isolating the chip flying from the cutting area. The protective sleeve deforms synchronously with the extension and retraction of the cutting seat, with no relative frictional wear.

[0021] 2. The present invention proposes an edge-cleaning machine for preventing chipping. Through the sliding cooperation between the arc-shaped protrusion of the slider and the waist-shaped hole of the blade fixing plate, the cutting mechanism automatically floats radially when the thickness of the plate changes abruptly, eliminating the cutting depth deviation caused by the unevenness of the plate. The elastic element buffers the impact load in real time, maintains constant pressure on the blade, and ensures that the cut surface is flat and burr-free.

[0022] 3. The present invention proposes an edge cleaning machine for preventing debris, wherein the elastic element is pre-pressed between the two retaining sleeves, so that the protective sleeve is in an open state. When the cutting vibration causes the component to shift slightly, the elastic element absorbs energy to prevent the protective sleeve from falling off or tearing.

[0023] 4. The edge cleaning machine for preventing debris proposed in this utility model can replace the protective sleeve by means of a hose clamp without disassembling the slide rod. The hose clamp and the retaining sleeve form a mechanical interlock to prevent debris from entering from the connection. Attached Figure Description

Detailed Implementation

[0029] The following is combined with Figs. 1-3 This utility model will be described in detail.

[0030] A chip-proof edge trimming machine for cutting edges of sheet metal, including

[0031] A cutting base is movably connected to a slide rod 20, and the cutting base is equipped with a cutting blade 103, which is used to cut the plate material;

[0032] The slide bar 20 has fixing members at both ends, and an elastic member 50 is provided between the fixing members and the cutting seat; and

[0033] The protective device includes a protective sleeve 40, which is disposed between the cutting seat and the fixing member of the slide rod 20 and surrounds the slide rod 20 and the elastic member 50. The protective sleeve 40 is kept open by the elastic action of the elastic member 50 to prevent debris from entering.

[0034] In this embodiment, the cutting seat includes a slider 101 and a blade fixing plate 102 nested from the inside out. The slider 20 passes through the slider 101, and the slider 101 is slidably connected to the blade fixing plate 102.

[0035] The inner slider 101 has a through hole at the center of its cylindrical metal body, which fits tightly onto the surface of the slide rod 20. Several arc-shaped protrusions 1011 are evenly distributed around its outer circumference, with the cross-section of each protrusion forming a continuous, smooth curved surface. The slider 101 is made of high-strength alloy steel, with a cylindrical sleeve-like structure whose outer diameter matches the guide hole of the cutting blade 103's blade fixing plate 102. Five arc-shaped protrusions 1011 are evenly machined around the sleeve's circumference. The surfaces of the arc-shaped protrusions 1011 are mirror-polished, with a roughness Ra≤0.2μm, ensuring sliding accuracy when in contact with the guide hole.

[0036] The outer blade fixing plate 102 is a box-type structure that covers the slider 101. Elongated oval guide holes are formed on both side walls, and arc-shaped protrusions 1011 extend into these holes to form a sliding pair. A carbide cutting blade 103 is mounted on the front end of the fixing plate via an adjustable clamp. The blade's rotation plane is perpendicular to the axis of the slide rod 20. A long, narrow guide hole is provided in the center of the blade fixing plate 102. The length of the guide hole is parallel to the axis of the slide rod 20, ensuring that when the slider 101 reciprocates along the slide rod 20, the arc-shaped protrusions 1011 form a "point-to-surface" contact sliding pair within the hole. The clearance between the arc-shaped protrusions 1011 and the guide hole is controlled within 0.02-0.05 mm to ensure sliding freedom.

[0037] When the blade contacts the plate: the reaction force of the plate pushes the blade fixing plate 102, the guide hole wall and the arc protrusion 1011 of the slider 101 to produce relative sliding, realizing the dual-degree-of-freedom compensated motion, the main cutting feed along the axis of the slide rod 20 and the horizontal offset along the long axis of the guide hole.

[0038] In this embodiment, the outer side of the slider 101 is provided with a plurality of arc-shaped protrusions 1011 around its central axis, and the blade fixing plate 102 is provided with a guide hole in the axial direction, with the arc-shaped protrusions 1011 abutting against the guide hole.

[0039] In this embodiment, the length direction of the slide bar 20 is the first direction, and the major diameter direction of the guide hole is the second direction, with the first direction perpendicular to the second direction. When the cutting seat cuts the plate, the blade fixing plate 102 and the slider 101 generate relative displacement, and the blade fixing plate 102 can slide along the first direction and / or the second direction. Further, a cutting blade 103 is provided on one side of the blade fixing plate 102, and the cutting blade 103 is used to cut the plate. When the plate is uneven, the cutting reaction force pushes the blade fixing plate 102, and the arc-shaped protrusion 1011 slides along the guide hole, achieving dual-degree-of-freedom compensation: the displacement in the first direction is for feed compensation, and the offset in the second direction is for plate width deviation compensation.

[0040] In this embodiment, first retaining sleeves 301 are symmetrically arranged at both ends of the blade fixing plate 102, and second retaining sleeves 302 are arranged at both ends of the slide rod 20. A protective sleeve 40 is provided between the first retaining sleeves 301 and the second retaining sleeves 302. The protective sleeve 40 is a cylindrical cloth sleeve with a certain degree of elasticity. The elastic element 50 is a compression spring that connects the two retaining sleeves, and the preload keeps the protective sleeve 40 in a taut state. The protective sleeve 40 is a cylindrical wear-resistant fabric sleeve with flanged edges at both ends covering the retaining sleeves, and the interior completely covers the slide rod 20 and the elastic element 50.

[0041] In this embodiment, an elastic element 50 is provided between the first stop sleeve 301 and the second stop sleeve 302, and the protective sleeve 40 surrounds the elastic element 50. The first stop sleeve 301 and the second stop sleeve 302 are symmetrically arranged at both ends of the blade fixing plate 102. Both are hollow cylindrical structures used to fix one end of the elastic cloth sleeve, forming a closed protective cavity. The cloth sleeve can be made of wear-resistant aramid fiber cloth to form a cylindrical cloth sleeve, which is fastened and sealed by a hose clamp; the other end is also fixed with a hose clamp as shown in the figure, forming a fully enclosed sealed structure to ensure that there are no wrinkles or tightness when moving with the slide rod 20.

[0042] In this embodiment, the protective device includes a hose clamp. The two ends of the protective sleeve 40 are respectively fitted onto the outer sides of the first retaining sleeve 301 and the second retaining sleeve 302, and are fixed by the hose clamp. The two ends of the protective sleeve 40 are flanged to cover the retaining sleeves, and the teeth of the hose clamp are embedded in the grooves or textures of the retaining sleeves.

[0043] In this embodiment, a support device is also included, comprising a support rod 801. The support rod 801 passes through the blade fixing plate 102 along a third direction perpendicular to the first and second directions, and the support rod 801 is movable along the second direction. The support device includes at least two support rods 801, the base of which is fixed symmetrically to both sides of the blade fixing plate 102 via adjustable mounting seats. The main body of the support rod 801 extends parallel to the third direction, and its end is provided with a rotatable support foot. The support rod 801 can be adjusted in displacement along the second direction via a sliding groove structure within the mounting seat. An adjusting spring is provided within the sliding groove, and the adjusting spring is connected to both sides of the base of the support rod 801 to ensure that the cutting seat adjusts the cutting in real time according to the width change of the plate material.

[0044] In this embodiment, the slide bar 20 is provided with nut seats 60 at both ends, and a base plate 70 is provided between the nut seat 60 at one end and the second stop sleeve 302.

[0045] The present invention provides an edge cleaning machine for preventing debris, and its usage method is as follows:

[0046] The drive mechanism pushes the plate along the slide bar 20 for feeding. The arc-shaped protrusion 1011 on the outer periphery of the slider 101 forms a dynamic fit with the waist-shaped hole on the inner wall of the blade fixing plate 102, so that the blade fixing plate 102 that fixes the cutting blade 103 approaches the edge of the plate synchronously. When the cutting blade 103 contacts the plate, the radial force generated by the change in plate thickness pushes the blade fixing plate 102 to move relative to the slider 101. At this time, the arc-shaped protrusion 1011 slides along the long axis of the waist-shaped hole. At the same time, the spring group between the first stop sleeve 301 and the second stop sleeve 302 is compressed and deformed to absorb the impact and maintain a constant cutting pressure. During the cutting process, the flying debris is completely isolated by the cylindrical cloth sleeve.

[0047] The two ends of the cloth sleeve are fastened to the first retaining sleeve 301 of the blade fixing plate 102 and the second retaining sleeve 302 of the lead screw end by hose clamps, respectively, and extend and retract synchronously with the base. After the cutting is completed, the base and the cloth sleeve return to their original positions through the elastic element 50. The operator can loosen the hose clamps and move the cloth sleeve axially for maintenance, or quickly replace the brush module for secondary trimming through the scraping fixing plate at the end of the lead screw.

[0048] During the trial operation of the particleboard production line, the modified edge-cleaning machine ran continuously for 800 hours without jamming, improving the average failure interval by more than 10 times compared to the original structure. The defect rate of surface pits in the subsequent gantry stacking process decreased from 3.2% to 0.15%, both meeting the requirements of the complex environment of the laminating workshop, and the long-term operational stability was effectively verified.

[0049] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
