Description

Technical Field

[0001] This invention relates to the field of umbrella handle polishing device technology, and more specifically to an umbrella handle polishing device. Background Technology

[0002] An umbrella is a tool for providing shade from the sun or protection from rain and snow. It is typically made of oiled paper, oilcloth, or plastic sheeting. The materials used in umbrella construction usually include stretchable fabric and other materials that can be used as a frame, along with binding thread. It is held up by hand. Although the umbrella was originally invented primarily to block sunlight, it is most commonly used as a tool to protect against rain. In the umbrella manufacturing process, the handle, as a crucial component, directly affects the overall quality and feel of the umbrella.

[0003] For example, in the prior art disclosure number CN220762076U, there is an umbrella handle polishing device. The prior art adjustment mechanism is designed such that when polishing the umbrella handle, the position of the polishing head is adjusted according to the position of the umbrella handle, and the semi-circular block and the middle seat are adjusted respectively, thereby ensuring multi-angle adjustment of polishing and improving the polishing effect.

[0004] Currently, umbrella handle polishing is mostly done manually with hand-held polishing tools. This method is not only labor-intensive and inefficient, but also makes it difficult to control the polishing precision. It can easily result in uneven surfaces, over-polishing, or incomplete polishing of the umbrella handle, making it impossible to guarantee the consistency of the umbrella handle. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, the present invention provides an umbrella handle polishing device. Through the cooperation of a feeding table, a feeding component, a first hollow gripper, and a second hollow gripper, the device achieves automatic feeding, conveying, positioning, clamping, and unloading of umbrella handles, reducing manual intervention and improving production efficiency. The first hollow gripper can drive the umbrella handle to rotate, and in conjunction with two openable polishing blocks, it can automatically polish the outer circumference of the umbrella handle, further improving polishing efficiency and solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an umbrella handle polishing device, comprising a processing table, a drive box fixedly mounted on the top of the processing table, a feeding table and a polishing table respectively mounted on both sides of the drive box, a first hollow gripper installed inside the drive box, a movable block mounted on the top of the polishing table, a second hollow gripper rotatably mounted on the side of the movable block near the drive box, the first hollow gripper and the second hollow gripper cooperating to fix the umbrella handle to be polished, door panels hinged to both the front and rear sides of the polishing table, a polishing assembly mounted on each of the two door panels, the polishing assembly comprising a polishing block, a first electric push rod connected to the center of the side of the two polishing blocks that are far apart, the first electric push rod fixedly penetrating through the door panel and extending to the outside of the door panel.

[0007] In a preferred embodiment, two symmetrically distributed first telescopic rods are fixedly provided on the inner walls of both door panels. The first telescopic rods are fixed to the grinding block to play a limiting role and improve the stability of the grinding block.

[0008] In a preferred embodiment, a motor is fixedly installed inside the drive box. The output shaft of the motor is connected to the first hollow gripper through a gear set. The motor serves as a power source and transmits power to the first hollow gripper through the gear set, causing the first hollow gripper to rotate. This, in turn, causes the umbrella handle that is clamped and fixed to rotate synchronously, thereby improving the polishing efficiency.

[0009] In a preferred embodiment, the drive box has through holes on both sides for conveying umbrella handles. The front end of the drive box has a detachable door, which is connected by bolts or buckles for easy disassembly and opening to inspect, maintain, and replace components such as the motor, the first hollow gripper, and the gear set inside the drive box.

[0010] In a preferred embodiment, the top of the feeding platform is provided with a feeding component, which includes a vertical plate. A second electric push rod is fixedly provided on the side of the vertical plate near the feeding platform for pushing the umbrella handle on the top of the feeding platform to achieve automatic feeding without manual pushing, thereby reducing labor intensity and improving feeding efficiency.

[0011] In a preferred embodiment, two supports are fixedly mounted on the top of the drive box. The bottom of the two supports is fixed to the top of the processing table and the top of the grinding table, respectively. A linear module is fixedly mounted on the bottom of each of the two supports. The vertical plate and the moving block are fixed to the bottom of the slide of the two linear modules, respectively. The linear modules can drive the slide to move in the horizontal direction, thereby realizing the automatic adjustment of the position of the vertical plate and the moving block.

[0012] In a preferred embodiment, a third electric push rod and a second telescopic rod are fixedly provided on the top of the processing table. The piston rod top of the third electric push rod is fixed to the bottom of the feeding table. The number of the second telescopic rods is set to four, and all four second telescopic rods are connected to the bottom of the feeding table. The four second telescopic rods are evenly distributed on the bottom of the feeding table, which plays a guiding and supporting role, preventing the feeding table from tilting during the lifting and lowering process, and further improving the stability of the feeding table.

[0013] In a preferred embodiment, a fourth electric push rod is fixedly provided in the groove at the top of the feeding platform, and a limiting plate is fixedly provided at the rear end of the piston rod of the fourth electric push rod. The limiting plate is used to limit the umbrella handle at the top of the feeding platform to prevent the umbrella handle from shifting during the feeding process and to ensure that the umbrella handle can be accurately pushed to the clamping position.

[0014] In a preferred embodiment, a dust suction head is fixedly inserted through the bottom of the grinding table, and an industrial vacuum cleaner is fixedly installed on the top of the processing table. The suction pipe of the industrial vacuum cleaner is connected to the dust suction head. When the industrial vacuum cleaner is working, it generates negative pressure, which sucks in the debris through the dust suction head and transports it to the dust collection box of the industrial vacuum cleaner through the suction pipe for centralized collection. This avoids debris from scattering and polluting the working environment, while also reducing the risk of debris being inhaled by the operator and protecting the operator's health.

[0015] In a preferred embodiment, the front end of the processing table has a plurality of rectangular through holes distributed at equal intervals, and the top of the processing table has a plurality of evenly distributed fixing holes. The fixing holes are used to fix the entire device to the ground or workbench with bolts, thereby further enhancing the stability of the device and preventing displacement due to vibration during operation.

[0016] The technical effects and advantages of this invention are as follows: 1. Through the cooperation of the feeding table, feeding components, first hollow gripper and second hollow gripper, the automatic feeding, conveying, positioning and clamping and unloading of umbrella handles are realized, reducing manual intervention and improving production efficiency. The first hollow gripper can drive the umbrella handle to rotate, and with the cooperation of two openable grinding blocks, it can automatically grind the outer surface of the umbrella handle, further improving grinding efficiency.

[0017] 2. The distance between the first and second hollow grippers is adjusted by the linear module, and the distance between the grinding blocks is adjusted by the first electric push rod, the height of the feeding table is adjusted by the third electric push rod, and the position of the limit plate is adjusted by the fourth electric push rod. It can adapt to the grinding needs of umbrella handles of different lengths and diameters, and has strong versatility. There is no need to equip grinding equipment separately for umbrella handles of different specifications.

[0018] 3. By using an industrial vacuum cleaner with a vacuum head, the debris generated during grinding can be collected in a centralized manner, preventing debris from scattering and polluting the environment, while also reducing the risk of operators inhaling the debris and protecting their health.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Refer to the instruction manual appendix Figures 1-8 The present invention provides an umbrella handle polishing device, including a processing table 1, a drive box 2 fixedly mounted on the top of the processing table 1, a feeding table 3 and a polishing table 4 respectively mounted on both sides of the drive box 2, a first hollow gripper 5 installed inside the drive box 2, a moving block 6 mounted on the top of the polishing table 4, and a second hollow gripper 7 rotatably mounted on the side of the moving block 6 near the drive box 2. The first hollow gripper 5 and the second hollow gripper 7 cooperate to fix the umbrella handle to be polished.

[0023] like Figure 2 , Figure 3 and Figure 5 As shown, door panels 8 are hinged to both the front and rear sides of the polishing table 4. Polishing components 9 are provided on both door panels 8. Each polishing component 9 includes a polishing block 901. A first electric push rod 902 is connected to the center of the two polishing blocks 901 on the side away from each other. The first electric push rod 902 is fixed through the door panel 8 and extends to the outside of the door panel 8. Furthermore, two symmetrically distributed first telescopic rods 903 are fixedly provided on the inner walls of both door panels 8. The first telescopic rods 903 are fixed to the grinding block 901 to play a limiting role and improve the stability of the grinding block 901.

[0024] like Figures 1-3As shown, a motor 201 is fixedly installed inside the drive box 2. The output shaft of the motor 201 is connected to the first hollow gripper 5 through a gear set 202. Both sides of the drive box 2 are provided with through holes 203 for conveying umbrella handles. A box door 204 is detachably installed at the front end of the drive box 2. The box door 204 is connected by bolts or buckles, which is convenient for disassembly and opening to inspect, maintain and replace the motor 201, the first hollow gripper 5, the gear set 202 and other components inside the drive box 2.

[0025] In this embodiment, motor 201 can be a servo motor, which has high-precision position control capability and can adjust the speed in real time through the feedback device to ensure that the umbrella handle rotates at a uniform and stable speed, avoid uneven polishing, and perfectly match the precision requirements of umbrella handle polishing; the speed is adjustable and can be flexibly adjusted according to the umbrella handle material (wood, plastic, etc.) and polishing precision requirements. With the gear set 202, the speed stability can be further optimized, the operation is smooth, the noise is low, and the response is fast, and it can start and stop quickly, which is suitable for the automated process of continuous umbrella handle polishing.

[0026] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, the top of the feeding platform 3 is provided with a feeding component 10, which includes a vertical plate 1001. A second electric push rod 1002 is fixedly provided on the side of the vertical plate 1001 near the feeding platform 3 for pushing the umbrella handle on the top of the feeding platform 3. Two brackets 11 are fixedly provided on the top of the drive box 2. The bottom of the two brackets 11 is fixed to the top of the processing table 1 and the top of the grinding table 4, respectively. Linear modules 12 are fixedly provided on the bottom of both brackets 11. The vertical plate 1001 and the moving block 6 are fixed to the bottom of the slide of the two linear modules 12, respectively. The linear modules 12 can drive the slide to move in the horizontal direction, thereby realizing the automatic adjustment of the position of the vertical plate 1001 and the moving block 6.

[0027] like Figure 1 , Figure 2 , Figure 6 and Figure 8 As shown, a third electric push rod 13 and a second telescopic rod 14 are fixedly provided on the top of the processing table 1. The top end of the piston rod of the third electric push rod 13 is fixed to the bottom of the feeding table 3. The number of the second telescopic rods 14 is set to four. All four second telescopic rods 14 are connected to the bottom of the feeding table 3 and are evenly distributed on the bottom of the feeding table 3. The four second telescopic rods 14 are evenly distributed on the bottom of the feeding table 3, which plays a guiding and supporting role, preventing the feeding table 3 from tilting during the lifting and lowering process, and further improving the stability of the feeding table 3.

[0028] The top groove of the feeding platform 3 is fixedly provided with a fourth electric push rod 15. The piston rod rear end of the fourth electric push rod 15 is fixedly provided with a limiting plate 16. The limiting plate 16 is used to limit the umbrella handle at the top of the feeding platform 3 to prevent the umbrella handle from shifting during the feeding process and to ensure that the umbrella handle can be accurately pushed to the clamping position.

[0029] In actual use, multiple umbrella handles are neatly placed on the top of the feeding platform 3. The fourth electric push rod 15 is adjusted so that the limiting plate 16 abuts against the front of the umbrella handle to complete the initial positioning. Then, the third electric push rod 13 drives the feeding platform 3 to rise as a whole, raising the umbrella handle on the feeding platform 3 to a height that is roughly level with the central axis of the first hollow gripper 5 and the second hollow gripper 7. Then, the linear module 12 on the top of the feeding component 10 is controlled so that the vertical plate 1001 drives the second electric push rod 1002 to move towards the umbrella handle, and then pushes the umbrella handle into the through hole 203. The linear module 12 on the top of the moving block 6 is controlled so that the second hollow gripper 7 moves to the left until it clamps the other end of the umbrella handle. At this time, the umbrella handle is firmly clamped by the first hollow gripper 5 and the second hollow gripper 7 at both ends. Next, the first electric push rods 902 on the two door panels 8 synchronously push the two grinding blocks 901 closer together, so that their inner surfaces fit against the outer circumference of the umbrella handle. Then, the motor 201 is started, and the gear set 202 drives the first hollow gripper 5 and the gripped umbrella handle to rotate at a constant speed. During the rotation, the entire outer surface of the umbrella handle rubs against the stationary grinding block 901, realizing automatic grinding. After grinding is completed, the motor 201 stops, the first electric push rods 902 retract, the door panels 8 open, the first hollow gripper 5 and the second hollow gripper 7 release, and the moving block 6 moves to the right to send the ground umbrella handle to the right side near the bracket 11 to facilitate the robotic arm (e.g., ...). Figure 1 , Figure 2 and Figure 6 (As shown) The umbrella handle is automatically pulled out for feeding, and finally all parts of the device are reset to prepare for the next work cycle.

[0030] In this invention, the motor 201, the first hollow gripper 5, the second hollow gripper 7, the first electric push rod 902, the second electric push rod 1002, the linear module 12, the third electric push rod 13, the fourth electric push rod 15, and the industrial vacuum cleaner 18 are all electrically connected to the equipment controller via wires (not shown in the figure). The controller can be a PLC controller, and its specific control logic can be implemented by programming with existing technology, which will not be elaborated further here.

[0031] In this embodiment, the first electric actuator 902, the second electric actuator 1002, the third electric actuator 13, and the fourth electric actuator 15 can all be other electric actuators such as servo electric actuators. Servo electric actuators have closed-loop position / speed / force control, high positioning accuracy, and high thrust control accuracy. After the operator measures the travel distance of these electric actuators in advance and sets the data, they can be automatically controlled by the controller.

[0032] like Figures 1-3 As shown, a dust suction head 17 is fixedly inserted through the bottom of the grinding table 4, and an industrial vacuum cleaner 18 is fixedly installed on the top of the processing table 1. The suction pipe of the industrial vacuum cleaner 18 is connected to the dust suction head 17 and is used to suck up the debris generated during grinding.

[0033] The top of the suction head 17 is flush with the surface of the grinding table 4, which makes it easy to collect debris. The debris generated during grinding is sucked away in real time by the industrial vacuum cleaner 18 below through the suction head 17. The suction pipe can be a flexible corrugated pipe, which is easy to adapt to the structural layout of the device. The dust collection box of the industrial vacuum cleaner 18 is detachable, which makes it easy to clean the collected debris.

[0034] like Figure 1 and Figure 2 As shown, the front end of the processing table 1 has multiple rectangular through holes 19 that are evenly spaced, and the top of the processing table 1 has multiple evenly distributed fixing holes 20 for fixing the entire device.

[0035] In conclusion, the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
