Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of plastic processing, and specifically relates to a plastic gear box for a beveling machine. BACKGROUND

[0002] The plastic gear box of the beveling machine is usually located at the key transmission part of the machine, and its function is to transmit the power of the motor to the cutting part of the beveling machine after gear deceleration, so as to realize precise cutting action. The specific position of the plastic gear box in the beveling machine may be different due to the design of the machine type and manufacturer, but it is usually located on the transmission path between the motor and the cutting knife.

[0003] A patent with publication number CN 107322216 A discloses a beveling machine, which comprises a base, two groups of tracks are arranged on the base, a first sliding block and a second sliding block are respectively arranged on the two groups of tracks, a stand is arranged on the first sliding block, a double swing mechanism capable of cutting in the radial and axial directions and an operation trolley are arranged on the stand, a bracket capable of adjusting the height is arranged on the second sliding block, a head box is arranged on the base, a clamping device is arranged on the head box, and the beveling machine generates high temperature during cutting. The heat resistance of plastic materials is usually lower than that of metals at high temperatures, and long-term exposure to high-temperature environments may cause the plastic gear box to deform or degrade in performance.

[0004] In the prior art, the plastic gear box functions to transmit the power of the motor to the cutting part of the beveling machine after gear deceleration, so as to realize precise cutting action. Due to the low strength and rigidity of the plastic gear box, the heat generated by the friction between the cutting knife and the material during high-speed rotation will be guided into the interior of the plastic gear box through the supporting connection device. The heat resistance of plastic materials is usually lower than that of metals at high temperatures, which may cause the surface of the plastic gear to soften slightly, and the softened plastic gear may deform slightly under pressure, thereby affecting the precision of the plastic gear transmission. Moreover, long-term exposure to high-temperature environments may cause the plastic gear box to deform or degrade in performance. To prevent the plastic gear from being exposed to high temperatures for a long time, air outside the plastic gear box is sucked into the interior of the plastic gear box. When the beveling machine cuts again, the material dust cut by the material will be scattered in the air and will be brought into the interior of the plastic gear box by the air pump. The dust will accumulate on the surface of the plastic gear, and as the gear is pressed, the dust will be embedded in the softened plastic gear, thereby affecting the service life of the plastic gear.

[0005] Therefore, a plastic gear box for a beveling machine is proposed to solve the above problems. UTILITY MODEL CONTENTS

[0031] Further, as Figures 1 to 7As shown, the top surface of the rotating disc 113 is fixedly connected with two groups of overlapping strips 1131, which are arranged at the two side edge positions of the cutting groove 115. The top surface of the overlapping strip 1131 is provided with a shock-absorbing soft pad 1132. The back surface of the overlapping strip 1131 is movably connected with an L-shaped support plate 1134. The outer side surface of the overlapping strip 1131 is fixedly connected with an elastic wire 1133, and the other end of the elastic wire 1133 is fixedly connected to the outer side surface of the L-shaped support plate 1134. The side edge position of the overlapping strip 1131 is provided with a limiting lock buckle 1135, and one end of the L-shaped support plate 1134 is detachably mounted on the inner side wall surface of the limiting lock buckle 1135. The inner side wall surface of the air collecting box 12 is provided with 123, and the top edge position of 123 is arranged at the bottom edge position of the cutting groove 115. The two side surfaces of the air collecting box 12 and located at the bottom edge position are fixedly connected with a drainage pipe 121, and the other end of the drainage pipe 121 is fixedly connected with a differentiation box 122 arranged at the bottom edge position of the bevel cutting machine 11. The inner side wall surface of the air suction filter box 14 is provided with a limiting sleeve 143, and the outer side surface of the filter sponge layer 144 is arranged on the inner side wall surface of the limiting sleeve 143.

[0032] In work, the long strip material is placed on the top surface of 1311, and the L-shaped support plate 1134 on the outer side surface of 1311 is overlapped on the surface of the material. One end of the L-shaped support plate 1134 is clamped to the inner side wall surface of the limiting lock buckle 1135 to limit the position of the L-shaped support plate 1134. The material is cut by the cutting blade 132 on the inner side wall surface of the protective sleeve 131. The slight vibration generated during the cutting of the material is buffered by the shock-absorbing soft pad 1132 on the inner side wall surface of 1311. The slight vibration generated during the cutting of the material is avoided, which can cause the material to tilt in position and affect the accuracy of the material cutting. After the material is cut, the end of the material is lifted and tilted, so that the end of the L-shaped support plate 1134 is lifted and separated from the limiting lock buckle 1135. Under the elastic pulling of the elastic wire 1133, the L-shaped support plate 1134 is completely separated from the top surface of the material.

[0033] Working principle: cooperate with the air guide pipe 141 on the output end of the air extraction filter box 14 to absorb the gas in the inside of the air collecting box 12, and at the same time, the cutting groove 115 on the top surface of the air collecting box 12 is used to extract the gas between the cutting blade 132 and the material. Since the space in the inside of the air collecting box 12 is relatively small, under the strong suction of the air extraction filter box 14, the gas on the top periphery of the rotating disc 113 will drive the airflow to pass through the cutting groove 115 and enter the inside of the air collecting box 12. With the continuous absorption of the airflow on the top periphery of the rotating disc 113, the dust generated during the cutting of the cutting blade 132 and the material will be absorbed downward, which can greatly reduce the effect that the dust generated during the cutting of the material will spread into the air.

[0034] With the continuous absorption of the gas in the air extraction filter box 14, the dust in the air is filtered by the filter sponge layer 144 in the inside of the air extraction filter box 14, and the filtered gas is guided into the inside of the protective sleeve shell 131 and the gear motor box 134 through the two air blowing and cooling pipes 142, respectively. The impact of the gas is used to impact and cool the plastic gear in the inside of the gear motor box 134, so that the plastic gear can always maintain the best normal temperature state.

[0035] Place the long material on the top surface of the 1311, and cooperate with the L-shaped supporting plate 1134 on the outer surface of the 1311 to overlap the surface of the material, and then clamp one end of the L-shaped supporting plate 1134 to the inner side wall of the limiting lock 1135 to limit the position of the L-shaped supporting plate 1134. Then, the cutting blade 132 on the inner side wall of the protective sleeve shell 131 is used to cut the material, and the shock-absorbing soft pad 1132 on the inner side wall of the 1311 is used to buffer the slight vibration generated during the cutting of the material. When one end of the material is lifted and raised after cutting the material, the end of the L-shaped supporting plate 1134 is lifted and separated from the limiting lock 1135. Under the elastic pulling of the elastic wire 1133, the L-shaped supporting plate 1134 is completely separated from the top surface of the material.

[0036] The above shows and describes the basic principle, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application.
