Description

Technical Field

[0001] This utility model belongs to the technical field of cloth wheel processing equipment, and in particular relates to a cloth wheel wooden nail screwing device. Background Technology

[0002] A cloth wheel is a wheel-shaped tool made of cloth, mainly used for polishing. In the later stages of making a cloth wheel, a layer of wood board needs to be glued to one side of the cloth wheel with white glue, and wooden nails are screwed into the wood board and the wood core of the cloth wheel in a circumferential array at certain positions to improve the connection strength between the wood board and the wooden nails.

[0003] An existing wood nail screwing device has a vertically arranged guide cylinder with its axis perpendicular to the path of the wood nail screwing position. An inclined tube is provided on one side of the guide cylinder to connect with the guide cylinder. The inclined tube is used for the wood nail to enter the guide cylinder. A rotating tapping cutter is coaxially arranged above the guide cylinder to screw the wood nail into the corresponding screwing position.

[0004] However, the friction of wooden nails is greater than that of ordinary bolts, which can easily cause the wooden nails to get stuck in the inclined tube, resulting in failure to load the wooden nails and affecting work efficiency. Utility Model Content

[0005] To address the shortcomings of the existing technology, this utility model provides a wooden nail screwing device that can effectively prevent wooden nails from falling off during the grasping process, thereby improving work efficiency.

[0006] In order to achieve the purpose of this utility model, the following solution is proposed: A cloth wheel wood nail screwing device is provided on one side of the feeding mechanism of the wood nail arranging mechanism and corresponding to the outer side of the cloth wheel conveyor belt. The cloth wheel conveyor belt is provided with a rotating clamping member in the conveying direction for positioning the cloth wheel. The device includes a wood nail screwing assembly and a nail taking assembly provided at the lower end of the wood nail screwing assembly. The wood nail screwing assembly includes a mounting platform, a telescopic rod is rotatably provided, a cantilever is provided vertically at the upper end of the telescopic rod, and a connecting rod is provided that moves along the length of the cantilever. The nail-removing assembly includes a mounting plate located at the lower end of the connecting rod, with a nail-removing cylinder rotatably mounted inside for accommodating the upper handle of the wooden nail. The rotation center of the rotating clamp and the output end of the wooden nail arranging and feeding mechanism are both on the arc of the nail-removing cylinder rotating around the telescopic rod. A clamping plate is rotatably mounted on one side of the mounting plate, with an arc-shaped opening at one end for engaging the vertical part of the wooden nail.

[0007] Furthermore, a limiting plate is provided on the mounting platform. The limiting plate has an L-shaped cross-section, with its horizontal part perpendicular to the conveying direction of the cloth wheel conveyor belt and its vertical part perpendicular to the conveying direction of the wood nail arrangement feeding mechanism. The rotatable connection between the cantilever and the telescopic rod corresponds to the angle bisector of the right angle inside the limiting plate.

[0008] Furthermore, a groove is provided along the length of the cantilever, and the cross-section of the groove is T-shaped. The connecting rod, including the slide block, is slidably disposed in the groove. A vertical rod is provided at the lower end of the slide block, and a connecting plate is provided on the top surface of the vertical rod. The width of the connecting plate is greater than the width of the groove. A locking bolt is vertically inserted through the top surface of the slide block, and the lower end of the locking bolt is connected to the connecting plate.

[0009] Furthermore, the lower end of the vertical rod is connected to the mounting plate, the plate is a horizontally set L-shaped structure, the arc-shaped opening is located at the outer end of the horizontal part of the plate, and one end of the vertical part of the plate is vertically provided with a rotating shaft, the upper end of the rotating shaft is rotatably connected to the bottom surface of the mounting plate.

[0010] Furthermore, the top surface of the cantilever is provided with a scale. When the cantilever is perpendicular to the long axis of the cloth wheel conveyor belt, the starting point of the scale is projected onto the horizontal plane and falls onto the long axis of the cloth wheel conveyor belt.

[0011] The beneficial effects of this utility model are as follows: The nail-removing cylinder is inserted into the handle of the wooden nail, and the arc-shaped opening on the horizontal part of the clamping plate acts on the vertical part of the wooden nail. The top surface of the horizontal part of the clamping plate acts on the bottom surface of the handle of the wooden nail. This prevents the wooden nail from falling when the nail-removing cylinder grabs the wooden nail, which would cause the nail to fail to be grabbed and affect the work efficiency. At the same time, the clamping plate can also prevent the vertical part of the wooden nail from being limited in the initial stage of screwing in, so as to prevent the wooden nail from being crooked.

Detailed Implementation

[0021] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figures 1-7 The embodiment shown provides a cloth wheel wood nail screwing device, which is located on the outside of the cloth wheel conveyor belt 3 and is used to screw wood nails 2 into the cloth wheel 5 on the cloth wheel conveyor belt 3. A rotating clamping member 4 is provided in the conveying direction of the cloth wheel conveyor belt 3 to limit the cloth wheel 5 during the process of screwing the wood nails 1 into the cloth wheel 5, and to rotate the screwing position of each wood nail on the cloth wheel 5 to the bottom of the device for screwing the wood nails 1 in sequence.

[0023] Specifically, such as Figures 1-4 As shown, the device includes a nail-picking assembly 10 and a wood nail-screwing assembly 20. The wood nail-screwing assembly 20 includes a mounting platform 21, a telescopic rod 22, a cantilever 23, and a connecting rod 24. The mounting platform 21 is located on the outside of the arrangement direction of the cloth wheel conveyor belt 3. The wood nail arranging and feeding mechanism 2 is located on one side of the mounting platform 21 and is used to feed wood nails 1 in a direction perpendicular to the conveying direction of the cloth wheel conveyor belt 3.

[0024] A limiting plate 211 is vertically mounted on the top surface of the mounting platform 21. The limiting plate 211 has an L-shaped cross-section, with its horizontal part perpendicular to the direction of the cloth wheel conveyor belt 3 and its vertical part perpendicular to the direction of the wood nail arrangement feeding mechanism 2. A telescopic rod 22 is vertically mounted on the mounting platform 21 and is located on the angle bisector of the right angle inside the limiting plate 211. The projection of the axis of the telescopic rod 22 in the direction of the cloth wheel conveyor belt 3 coincides with the rotation axis of the rotating clamp 4.

[0025] The cantilever 23 is set horizontally, and one end of the cantilever 23 is set perpendicular to the upper end of the telescopic rod 22. A groove 231 is provided along the length direction of the cantilever 23, and scale lines 232 are provided on the top surface of the two side walls of the groove 231. When the length direction of the cantilever 23 is perpendicular to the length direction of the cloth wheel conveyor belt 3, the projection of the starting position of the scale line 232 on the cantilever 23 onto the rotating clamp 4 coincides with the rotation center of the rotating clamp 4.

[0026] The connecting rod 24 includes a slide block 241, a vertical rod 242, a connecting plate 243, and a connecting bolt 244. The slide block 241 has a T-shaped structure. Its horizontal part slides and engages with the top surface of the slide groove 231, and its vertical part engages with the slide groove 231. The connecting plate 243 is located at the lower end of the vertical part of the slide block 241 and at the bottom of the cantilever 23. The vertical rod 242 is vertically located at the center of the bottom surface of the connecting plate 243. The top surface of the horizontal part of the slide block 241 has a threaded hole that passes through the lower end of the vertical part of the slide block 241 and the connecting plate 243 in sequence. The connecting bolt 244 is threaded into the threaded hole.

[0027] In use, the position of the slide block 241 in the slide groove 231 is determined according to the distance between the position of the wooden nail 1 screwed into the cloth wheel 5 and the center of the cloth wheel 5. Then, the connecting bolt 244 is passed through the slide block and connected to the connecting plate 243 to fix the slide block 231, thereby determining the distance between the axis of the vertical rod 242 and the scale line 232.

[0028] like Figures 3-5 As shown, the nail removal assembly 10 includes a mounting plate 11, a nail removal cylinder 12, and a clamping plate 13. The mounting plate 11 is located at the lower end of the vertical rod 242, and the nail removal cylinder 12 is located on the bottom surface of the mounting plate 11. The nail removal cylinder 12 is coaxial with the vertical rod 242. The lower end of the vertical rod 242 extends into the mounting plate 11 and is equipped with a rotary motor. The output end of the rotary motor is connected to the upper end of the nail removal cylinder 12. The cross-sectional shape of the inner wall of the nail removal cylinder 12 is adapted to the shape of the upper handle of the wooden nail 1.

[0029] like Figures 6-7 As shown, when removing the nail, the telescopic rod 22 rotates so that the cantilever 23 moves towards the vertical part of the limiting plate 211. When the cantilever 23 is in contact with the vertical part of the limiting plate 211 on the side facing the vertical part of the limiting plate 211, the telescopic rod 22 moves vertically downward so that the nail-removing cylinder 12 moves vertically downward along the output end of the nail-arranging feeding mechanism 2, directly above the nail 1, so that the upper end handle of the nail 1 enters the nail-removing cylinder 12.

[0030] The card plate 13 is located on the bottom surface of the mounting plate 11 and on one side of the nail-removing cylinder 12. The projection of the card plate 13 on the horizontal plane is L-shaped. The horizontal part away from the vertical part is provided with an arc-shaped opening 131. The opening size of the arc-shaped opening 131 is adapted to the outer side of the vertical part of the wooden nail 1. A rotating shaft 132 is vertically provided at the vertical part of the card plate 13 away from the horizontal part. The upper end of the rotating shaft 132 is rotatably connected to the mounting plate 11. The rotation of the rotating shaft 132 can be driven by a motor.

[0031] After the upper end of the wooden nail 1 enters the nail-removing cylinder 12, the rotating shaft 132 is rotated so that the clamping plate 13 rotates in the direction of the opening of its arc-shaped opening 131 toward the nail-removing cylinder 12, so that the arc-shaped opening 131 is engaged with the vertical part of the wooden nail 1, and the top surface of the horizontal part of the clamping plate 13 contacts the bottom surface of the nail-removing cylinder 12. Finally, the telescopic rod 22 is activated vertically upward, so that the wooden nail 1 is prevented from falling into the nail-removing cylinder 12 under the action of the nail-removing cylinder 12 and the clamping plate 13.

[0032] After the nail-removing cylinder 12 moves vertically upward and completely out of the output of the nail-arranging and feeding mechanism 2 along with the telescopic rod 22, the telescopic rod 22 is rotated so that the telescopic rod 22 drives the cantilever 23 to rotate in the opposite direction to the horizontal part of the limiting plate 211. When the cantilever 23 is in contact with the horizontal part of the limiting plate 211, the nail-removing cylinder 12 drives the nail 1 to rotate above the nail-screwing distribution trajectory of the cloth wheel 5.

[0033] When the cloth wheel 5 moves with the cloth wheel conveyor belt 3 to above the rotating clamp 4, the rotating clamp 4 will clamp and position the cloth wheel 5, and cause the wooden nail screwing position to rotate sequentially to directly below the nail take-up cylinder 12 for the wooden nail to be screwed in.

[0034] The specific operation process is as follows: The cloth wheel 5 is conveyed sequentially along the conveying direction of the cloth wheel conveyor belt 3, and the wooden nails 1 are conveyed sequentially along the conveying direction of the wooden nail arrangement feeding mechanism 2. When the cloth wheel 5 is conveyed to the top of the rotating clamp 4, the rotating clamp 4 rotates the cloth wheel 5 so that the wooden nail screw-in position on the top surface of the cloth wheel 5 rotates to the line connecting the rotation center line of the rotating clamp 4 and the axis of the telescopic rod 22. The rotation of the rotating clamp 4 is then paused. The wooden nail screw-in position can be determined by setting a sensor on the top surface of the rotating clamp 4. When the cloth wheel 5 enters the rotating clamp 4, the screw-in position of the wooden nail on the cloth wheel 5 is automatically identified. This is existing technology and will not be described in detail.

[0035] Rotate the telescopic rod 22 to move the nail-removing cylinder 12 directly above the output end of the wood nail arranging and feeding mechanism 2. Then, the telescopic rod 22 descends vertically to insert the nail-removing cylinder 12 into the upper handle of the wood nail 1. Start the rotating shaft 132 to rotate the horizontal part of the clamping plate 13 to the bottom of the nail-removing cylinder 12 to limit the position of the wood nail 1.

[0036] The telescopic rod 22 moves vertically upward to remove the wooden nail 1. Then, the telescopic rod 22 rotates in the opposite direction, causing it to move the nail-removing cylinder 12 directly above the nail's insertion position. This completes the nail removal process. Figures 4-5 As shown, the telescopic rod 22 is vertically downward and rotates the nail-removing cylinder 12 simultaneously so that the wooden nail 1 is screwed into the cloth wheel 1. After the wooden nail 1 is screwed in to a certain length, the rotating shaft 132 is rotated in the same direction, so that the clamping plate 13 is moved out directly below the nail-removing cylinder 12.

[0037] After a wooden nail 1 is screwed in, the rotating clamp 4 drives the cloth wheel 5 to rotate at a certain angle so that the position for the next wooden nail to be screwed in is aligned with the line connecting the rotation center line of the rotating clamp 4 and the axis of the telescopic rod 22. The above nail removal process is repeated so that the next wooden nail 1 is screwed in into the corresponding nail screwing circle.

[0038] Preferably, in order to ensure that the wooden nail 1 is screwed in in one go, the rotating shaft 132 can be set as a telescopic structure. After the wooden nail is screwed in a certain length, the rotating shaft 132 rotates in the direction of rotation so that the clamping plate moves out of the nail-removing cylinder 12. The telescopic rod 22 continues to drive the cantilever 23 to move downward, so that the nail-removing cylinder 12 continues to move downward and rotate, so that the wooden nail 1 can be screwed in in one go. At this time, the rotating shaft 132 is kept compressed under the action of the mounting plate 11 and the cloth wheel 5.

[0039] Once the wooden nails are screwed in, the telescopic rod 22 moves vertically upward, the rotating shaft 132 automatically extends, and the clamping plate 13 returns to its position below the nail-removing cylinder 12.

[0040] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
