A saw blade protection mechanism

Abstract

This utility model discloses a saw blade protection mechanism, relating to the technical field of cutting equipment for low-density foamed materials such as pearl cotton and EVA. Specifically, it is a saw blade protection mechanism installed on the frame of a pearl cotton integrated machine. The saw blade protection mechanism includes a cutting component and at least one protective component. The cutting component includes a saw blade with double-edged edges. The protective component includes a protective plate bracket and two protective blocks. The protective plate bracket is mainly composed of two vertical plate segments. By setting the protective blocks, whose material hardness is lower than that of the saw blade, and by installing the protective blocks on both sides of the saw blade, it can effectively prevent the saw blade from falling off the band saw wheel due to increased resistance caused by changes in the density of the material being cut or the increase in the cutting surface during the reciprocating operation of the saw. This prevents the saw blade from falling off and protects the cutting edge of the saw blade. This design not only extends the service life of the saw blade but also ensures the stability of the cutting quality, solving the problems of easily damaged saw blade edges and saw blade falling off in the prior art.

Description

Technical Field

[0001] This utility model relates to the technical field of pearl cotton cutting equipment, specifically a saw blade protection mechanism. Background Technology

[0002] In the field of EPE foam processing, cutting equipment is an indispensable tool. In existing technologies, most saw blades for cutting EPE foam employ a single-sided cutting design, and their support and limiting structures typically utilize bearings to support the unsharpened or toothed side of the saw blade. While patent application CN116653049A provides an integrated machine and method for using EPE foam stamping, waste removal, cutting, and backfilling, its cutting device is not optimized for the specific needs of double-sided cutting saw blades.

[0003] This traditional support method is not only ineffective in supporting and limiting double-edged saw blades, but may also damage the blade edge during operation, affecting cutting quality and the blade's lifespan. Furthermore, existing cutting equipment needs improvement in cutting efficiency, especially when bidirectionally cutting materials such as pearl cotton. The lack of effective support and protection structures leads to low cutting efficiency and the saw blade is prone to slipping, posing a safety hazard. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a saw blade protection mechanism, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a saw blade protection mechanism installed on the frame of an integrated pearl cotton machine. The saw blade protection mechanism includes a cutting component and at least one protective component. The cutting component includes a saw blade with double-edged edges. The protective component includes a U-shaped plate and two protective blocks. The U-shaped plate has a groove in its center and is mainly composed of a horizontal section and two vertical sections. The two protective blocks are detachably installed on the two vertical sections of the U-shaped plate, and both protective blocks are located within the groove in the center of the U-shaped plate. A protective position is formed between the two protective blocks. The saw blade passes through the protective position between the two protective blocks.

[0006] Optionally, the protective component further includes a support strip, one end of which is fixedly installed with the U-shaped plate, and the other end of which is fixedly installed with the cutting component.

[0007] Optionally, the cutting component further includes a supporting beam, a first supporting plate, a second supporting plate, a driving wheel, and a driven wheel. The first supporting plate and the second supporting plate are respectively fixedly installed above the two ends of the supporting beam. The driving wheel is rotatably installed on one side wall of the second supporting plate, and the driven wheel is rotatably installed on one side wall of the first supporting plate. The saw blade is sleeved on the outer circumferential wall of the driving wheel and the driven wheel, and the driving wheel is connected to the driven wheel through the saw blade. The end of the support bar away from the U-shaped plate is fixedly installed to the first supporting plate or the second supporting plate.

[0008] Optionally, the cutting component further includes a motor, which is connected to the drive wheel and drives the drive wheel to rotate.

[0009] Optionally, the material hardness of the protective block is lower than that of the saw blade.

[0010] Optionally, the protective block may be made of one of the following materials: nylon, copper, aluminum, synthetic fiber, engineering plastic, or rubber.

[0011] This utility model provides a saw blade protection mechanism, which has the following beneficial effects: 1. This saw blade protection mechanism, by incorporating protective blocks made of a material with a lower hardness than the saw blade itself, and with these blocks installed on both sides of the saw blade, effectively prevents the saw blade from directly contacting hard components during operation, thereby protecting the saw blade's cutting edge. This design not only extends the saw blade's service life but also ensures the stability of cutting quality, solving the problem of easily damaged saw blade cutting edges in existing technologies.

[0012] 2. This saw blade protection mechanism uses a double-edged saw blade, combined with unique protective components, enabling bidirectional cutting of materials. Compared to traditional unidirectional cutting, bidirectional cutting significantly improves cutting efficiency and reduces cutting time and equipment operating costs. Simultaneously, the detachable design of the protective blocks allows for quick replacement of the saw blade or protective blocks after damage, further improving equipment operating efficiency. The two protective blocks support and protect the saw blade from both sides, effectively preventing the saw blade from slipping, reducing safety hazards, and improving cutting efficiency.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0018] Please see Figures 1 to 3 This utility model provides a technical solution: a saw blade protection mechanism shown in this technical solution is implemented in conjunction with an EPE foam cutting device in practical applications. The EPE foam cutting device includes, but is not limited to, an integrated machine for EPE foam stamping, waste removal, cutting, and backfilling, and its usage method, as disclosed in Chinese patent application CN116653049A.

[0019] A saw blade protection mechanism is installed on the frame of a cutting machine made of low-density foam materials such as pearl cotton and EVA. The saw blade protection mechanism includes a cutting component 1 and at least one protective component 3.

[0020] When this technical solution is implemented in conjunction with an integrated machine for stamping, cleaning, cutting, and backfilling pearl cotton, a saw blade protection structure shown in this technical solution is installed on the integrated frame 2 of the pearl cotton machine in the integrated machine for stamping, cleaning, cutting, and backfilling pearl cotton.

[0021] The cutting component 1 includes a saw blade 102 with double-edged blades.

[0022] The protective component 3 includes a U-shaped plate 301 and two protective blocks 303. The U-shaped plate 301 has a groove in the middle and is mainly composed of a horizontal plate segment and two vertical plate segments.

[0023] Two protective blocks 303 are detachably mounted on the two vertical sections of the U-shaped plate 301, and both protective blocks 303 are located in the central groove of the U-shaped plate 301. A protective position is formed between the two protective blocks 303. The saw blade 102 passes through the protective position between the two protective blocks 303.

[0024] The protective component 3 also includes a support bar 302, one end of which is fixedly installed with the U-shaped plate 301, and the other end of which is fixedly installed with the cutting component 1.

[0025] The U-shaped plate 301 has a recessed center, consisting of one horizontal segment and two vertical segments. This unique structural design provides installation space for the protective block 303. This design of the protective block 303 effectively prevents the saw blade 102 from directly contacting hard parts during operation, protecting the cutting edge of the saw blade 102. One end of the support bar 302 is fixedly installed (including detachable installation) to the U-shaped plate 301, and the other end is fixedly installed to the cutting component 1, serving as a connection and support to ensure a tight connection between the protective component 3 and the cutting component 1, thus improving the stability of the entire mechanism.

[0026] More specifically, the cutting component 1 also includes a supporting beam 101, a first supporting plate 107, a second supporting plate 103, a driving wheel 104, and a driven wheel 108. The first supporting plate 107 and the second supporting plate 103 are respectively fixedly installed above the two ends of the supporting beam 101. The driving wheel 104 is rotatably installed on one side wall of the second supporting plate 103, and the driven wheel 108 is rotatably installed on one side wall of the first supporting plate 107. The saw blade 102 is sleeved on the outer circumferential wall of the driving wheel 104 and the driven wheel 108, and the driving wheel 104 is connected to the driven wheel 108 through the saw blade 102. The end of the support bar 302 away from the U-shaped plate 301 is fixedly installed (including detachable installation) to the first supporting plate 107 or the second supporting plate 103. The cutting component 1 also includes a motor 106, which is connected to the driving wheel 104 and drives the driving wheel 104 to rotate. The output shaft of the motor 106 is fixedly mounted with a second pulley, and the rotating shaft of the drive wheel 104 is fixedly mounted with a first pulley 105 (the drive wheel 104 is fixedly connected to the rotating shaft, the rotating shaft passes through the second support plate 103 and the two are rotatably connected), and the second pulley and the first pulley 105 are connected by belt drive.

[0027] The support beam 101 serves as the support structure for the entire cutting component 1. The rotation of the drive wheel 104 drives the saw blade 102 to move, achieving the cutting function. The motor 106 is connected to the drive wheel 104, providing power to the cutting component 1. A second pulley is fixedly mounted on the output shaft of the motor 106, and a first pulley 105 is fixedly mounted on the rotation shaft of the drive wheel 104. The second pulley and the first pulley 105 are connected via a belt drive to ensure effective power transmission.

[0028] Specifically, the material hardness of the protective block 303 is lower than that of the saw blade 102. The material of the protective block 303 includes, but is not limited to, nylon, copper, aluminum, synthetic fiber, engineering plastic, and rubber.

[0029] The protective block 303 is made of a material with a lower hardness than the saw blade 102, which helps to prevent damage when the saw blade 102 comes into contact with the protective block 303. It also effectively prevents the saw blade 102 from slipping and from directly contacting and damaging other hard parts on the equipment.

[0030] The detachable installation methods of the protective block 303 and the vertical section of the U-shaped plate 301 include, but are not limited to, threaded connection using bolts, riveting using rivets, and snap-fitting.

[0031] In use, the saw blade protection mechanism of this utility model is installed on the frame 2 of the integrated pearl cotton machine. When cutting is required, the motor 106 starts, driving the drive wheel 104 to rotate via belt drive, which in turn drives the saw blade 102 to move. During the movement of the saw blade 102, the protective block 303 limits the saw blade 102, preventing it from slipping and avoiding contact between the saw blade 102's cutting edge and hard parts, thus protecting the cutting edge of the saw blade 102. Because the saw blade 102 has a double-edged design, combined with the protective function of the protective block 303, it can achieve bidirectional cutting of materials such as pearl cotton, greatly improving cutting efficiency. When the protective block 303 is damaged due to long-term use, it can be disassembled and replaced to ensure the normal operation of the equipment.

[0032] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model, and no reference numerals in the claims should be construed as limiting the scope of the claims.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
