Description

Technical Field

[0001] The utility model relates to a turning device, in particular to a turning device for a sanding machine. Background Art

[0002] A sanding machine is a mechanical equipment used for grinding, deburring and cleaning raw materials such as wood and leather. It is widely used in the industrial field. Sanding machines are mainly divided into two types: disc sanding and belt sanding. Disc sanding is also called windmill sanding or grinding wheel sanding, which is suitable for special-shaped sanding, but has poor heat dissipation performance and low sanding efficiency; belt sanding is also called sanding belt sanding, which has better heat dissipation performance and higher sanding efficiency, and is suitable for sanding flat surfaces and relatively regular objects, but has poor sanding operations on special-shaped objects.

[0003] When a sanding machine processes an object, it can generally only sand one side of the object. Usually, manual flipping is required to achieve sanding on both sides. This is not only complicated to operate, but also reduces labor efficiency. Most existing flipping devices are semi-mechanical structures, which require manual operation during the flipping process and have a complex structure and are prone to failure.

[0004] Therefore, it is necessary to design a sanding machine turning device that can automatically turn over. Utility Model Content

[0005] In order to overcome the disadvantages of the existing sanding machine turning device that the manual operation is time-consuming and labor-intensive, the utility model provides a sanding machine turning device.

[0006] The technical implementation scheme of the utility model is: a sanding machine flipping device, including a frame, a transportation component, a support frame, a servo motor, a grinding wheel, a fixing component, an adjusting component, a sanding belt, a rotating rod, a fan wheel and a controller, the frame is symmetrically fixed with the transportation component, the rear side surfaces on the left and right sides of the frame are symmetrically fixed with the support frames, the upper parts of the two support frames are both equipped with servo motors, the two servo motors are both in a horizontal state relative to the ground, the front output shafts of the two servo motors are both fixed with grinding wheels, the sides of the two support frames close to each other are each provided with a fixing component, the middle and upper parts of one side of the two support frames are each provided with an adjusting component, the fixing components on both sides and the adjusting components and the periphery of the grinding wheel are fixedly sleeved with sanding belts, a rotating rod is rotatably connected between the front and rear sides of the middle part of the frame, the periphery of the rotating rod is fixedly and interlacedly connected with the fan wheel, the fan wheel is provided with a plurality of I-shaped grooves along the circumferential direction, a controller is installed on the front side of the middle part of the frame, a dust removal mechanism for cleaning a workpiece is symmetrically provided on one side of the frame, and a clamping mechanism for limiting the position of the workpiece is provided on the upper part of one side of the frame.

A discharge pipe is fixed to the lower part of one side of the storage box, and the discharge pipe is connected to the interior of the storage box.

[0008] Furthermore, the positioning mechanism includes a fixed block, a fixed rod, a spring, a torsion spring and a spring leaf. A fixed block is symmetrically fixed to the upper part of one side of the frame in a front-to-back manner, a fixed rod is fixed between the middle parts of the two fixed blocks, a spring leaf is rotatably sleeved on the outer periphery of the fixed rod, a torsion spring is circumferentially connected between the fixed block and the left and right ends of the spring leaf, and a spring leaf is symmetrically fixed to the inner side of the lower part of the fixed block in a front-to-back manner.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment: A sanding machine turning device, such as Figure 1 ,Figure,2, Figure 3 and Figure 5 As shown, it includes a frame 1, a transport component 2, a support frame 3, a servo motor 4, a grinding wheel 5, a fixing component 6, an adjusting component 7, a grinding belt 8, a rotating rod 9, a fan wheel 10 and a controller 11. The frame 1 is symmetrically connected with the transport component 2 by bolts. A certain transport length is left on the left and right sides of the two transport components 2. The rear sides of the left and right sides of the frame 1 are symmetrically welded with support frames 3. The servo motors 4 are installed on the upper parts of the two support frames 3. The two servo motors 4 are in a horizontal state relative to the ground. The front output shafts of the two servo motors 4 are fixedly connected with the grinding wheel 5. The two support frames 3 are each provided with a fixing component 6 on the side close to each other. An adjusting assembly 7 is provided in the middle and upper part of the front side of the two supporting frames 3, and a grinding belt 8 is fixedly sleeved between the fixing assemblies 6 on both sides and the outer periphery of the adjusting assembly 7 and the grinding wheel 5. A rotating rod 9 is rotatably connected between the front and rear sides of the middle part of the frame 1, and a fan wheel 10 is fixedly and insertedly connected to the outer periphery of the rotating rod 9. The fan wheel 10 has 6 I-shaped grooves along the circumference, and the width of the I-shaped grooves in the fan wheel 10 corresponds to the distance between the bottom of the grinding belt 8 and the transport assembly 2. A controller 11 is installed on the front side of the middle part of the frame 1, and a dust removal mechanism for cleaning the workpiece is symmetrically provided on the left and right sides of the front side of the frame 1, and a clamping mechanism for limiting the workpiece is provided on the upper left side of the frame 1.

[0022] When people need to trim the surface of workpieces such as wood and leather, this device can be used. The device is placed horizontally at the position where the surface of the workpiece needs to be trimmed, and the use status of the parts of the device is checked to see if they are in good condition. If so, the waste collection bag is tied to the outlet of the discharge pipe 14, and the collection frame is placed on the right side of the frame 1, and then the power is turned on.

[0023] like Figure 1 As shown, the dust removal mechanism includes a storage box 12, a dust collector 13 and a discharge pipe 14. The storage box 12 is symmetrically connected to the front side of the frame 1 by bolts. The dust collector 13 is installed on the top of the storage box 12. The suction port of the dust collector 13 is flush with the top of the transport component 2. The discharge pipe 14 is fixedly connected to the lower left side of the storage box 12, and the discharge pipe 14 is connected to the inside of the storage box 12.

[0024] When people need to trim the surface of wood, leather and other workpieces, first adjust the position of the adjustment component 7 and the fixing component 6 to tighten the sanding belt 8 to prevent the sanding belt 8 from being misplaced during the operation of the device. Then operate the controller 11 to start the device. The servo motor 4, the transport component 2, the fan wheel 10 and the vacuum cleaner 13 are operated at the same time. Then, the workpiece is placed from the left side of the frame 1 into the left side of the transport component 2. During the placement process, the workpiece will squeeze the spring 17 and the spring 19 to a certain extent. The spring 17 rotates counterclockwise at a certain angle. At this time, the torsion spring 18 is under pressure. Since the spring 1 7 and the spring leaf 19 are both made of spring steel with good resilience. When the two spring leaves 19 are subjected to the extrusion force on the front and rear sides, they produce a certain deformation, and then are stably transported to the right under the joint action of the transport component 2. At the same time, the output shaft of the servo motor 4 drives the grinding wheel 5 and the sanding belt 8 to rotate clockwise at the same time. When the workpiece contacts the sanding belt 8, since the sanding belt 8 is a belt-shaped tool made of abrasive bonded to a flexible material, the sanding belt 8 rubs against the upper surface of the workpiece when rotating at a high speed, thereby realizing the grinding and polishing of the upper surface of the workpiece, thereby completing the finishing work of the upper surface of the workpiece.

[0025] like Figure 1 and Figure 4 As shown, the locking mechanism includes a fixed block 15, a fixed rod 16, a spring 17, a torsion spring 18 and a spring 19. The upper left side of the frame 1 is symmetrically connected to the fixed block 15 by bolts. A fixed rod 16 is fixedly connected between the middle parts of the two fixed blocks 15. The outer periphery of the fixed rod 16 is rotatably sleeved with a spring 17. The torsion spring 18 is circumferentially connected between the left and right ends of the fixed block 15 and the spring 17. The spring 19 is symmetrically welded to the inner side of the lower part of the fixed block 15. Both the spring 17 and the spring 19 are made of spring steel with good resilience. Both the spring 17 and the spring 19 can lock and transport the workpiece through elasticity.

[0026] After completing the trimming work on the upper surface of the workpiece, the workpiece continues to be transported to the right. Since the width of the I-shaped groove opened in the fan wheel 10 corresponds to the distance between the bottom of the abrasive belt 8 and the transport component 2, when the workpiece contacts the fan wheel 10, the workpiece is transported to a certain distance in the I-shaped groove. At the same time, the fan wheel 10 drives the workpiece to rotate 90° clockwise to turn the workpiece over. After the rotation, the workpiece continues to be transported to the right until it contacts the right side abrasive belt 8. Similarly, the abrasive belt 8 grinds and polishes the upper surface of the turned-over workpiece, and finally transports it to the collection frame, thereby completing the trimming work on the upper surface of the workpiece.

[0027] When the sanding belt 8 is trimming the workpiece surface, the vacuum cleaner 13 simultaneously stores the waste generated by the workpiece surface trimming into the storage box 12, and then discharges the waste into a pre-prepared waste collection bag through the discharge pipe 14, thereby completing the collection of the workpiece waste.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
