Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, and in particular to an umbrella handle polishing device. Background Technology

[0002] The umbrella handle is the part of the umbrella that is held in place. The umbrella handle is formed by injection molding, and rough edges will be generated at the seam on the inner and outer sides. Therefore, it is necessary to use grinding equipment to treat the rough edges on the umbrella handle to improve the appearance and quality of the umbrella handle.

[0003] For example, Chinese utility model patent application number CN202223004202.2 discloses an umbrella handle polishing device for umbrella processing, belonging to the umbrella processing field. This device includes a polishing box, with a fixed polishing roller installed in the middle of the inner side of the polishing box, positioned at the upper end. The fixed polishing roller is rotatably connected to the polishing box via bearings. A movable polishing roller is installed at the upper end of the fixed polishing roller. This device can polish the hook-shaped umbrella handle. The umbrella handle is formed after injection molding, resulting in burrs at the inner and outer seams. The fixed polishing roller, movable polishing roller, and limiting component limit the umbrella handle, improving the device's safety. Simultaneously, an arc-shaped rack drives the limiting component and the umbrella handle to rotate, polishing the outer side of the handle. Activating the electric push rod pushes the handle forward, allowing polishing of the outer side of the straight shaft at the rear end of the handle, improving polishing efficiency and the practicality of the device.

[0004] While the aforementioned polishing device can polish the rough edges generated at the center seam on the inner and outer sides of the umbrella handle, it cannot polish the part of the umbrella handle located inside the limiting sleeve, resulting in polishing dead corners. Furthermore, workers are required to manually polish the umbrella handle a second time afterward, reducing the processing efficiency of the umbrella handle. In addition, after the umbrella handle is polished, workers need to manually remove the umbrella handle from the limiting sleeve before it can be installed. The loading and unloading efficiency of the umbrella handle is slow, further reducing the polishing efficiency of the umbrella handle. Utility Model Content

[0005] This utility model discloses an umbrella handle grinding device, which solves the problems of grinding dead corners in umbrella handles and slow loading and unloading efficiency of umbrella handles.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An umbrella handle polishing device includes a polishing machine body, one side of which is open and connected to a connecting frame. A first electric telescopic rod is provided in the connecting frame, and the telescopic end of the first electric telescopic rod is provided with a cylinder. A lead screw is provided in the connecting frame and threadedly connected to the first electric telescopic rod. A motor with a rotating shaft fixed in the connecting frame and fixed to one end of the lead screw is fixed in the connecting frame. A push plate is provided on the side of the cylinder away from the polishing machine body. A second electric telescopic rod is provided in the connecting frame for driving the push plate to approach the cylinder.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] After the curved part of the umbrella handle is polished, the handle is pushed towards the connecting frame for polishing of the straight part. When the curved part of the handle is between the cylinder and the push plate, the first electric telescopic rod is activated to drive the cylinder upward, aligning it with the curved part of the handle, with the top of the cylinder contacting the bottom of the straight part of the handle. After polishing, the handle is returned to its original position within the polishing machine body, with the cylinder positioned within the curved part of the handle and in contact with it. The telescopic end of the second electric telescopic rod then drives the push plate closer to the cylinder, which in turn holds the handle in place. As the handle continues to move towards the polishing machine body, it eventually reaches its inner limit. The part in the sleeve is separated from the limiting sleeve. Then, the motor is started to drive the lead screw to rotate, causing the first electric telescopic rod to move the cylinder away from the grinding machine body. At the same time, the second electric telescopic rod is started to drive the push plate away from the grinding machine body. As the umbrella handle moves into the connecting frame, the part of the umbrella handle that was previously located in the limiting sleeve can be ground, and the unloading of the umbrella handle is completed. The worker can then use the limiting sleeve in the grinding machine body to fix the umbrella handle to be ground into the grinding machine body. This utility model can perform all-round grinding of the umbrella handle, avoid the existence of grinding dead corners of the umbrella handle, and can automatically complete the unloading of the umbrella handle, thus improving the processing efficiency of the umbrella handle.

[0014] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0015] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides an umbrella handle polishing device, including a polishing machine body 1. One side of the polishing machine body 1 is open and connected to a connecting frame 2. A first electric telescopic rod 3 is provided in the connecting frame 2, and the telescopic end of the first electric telescopic rod 3 is provided with a cylinder 31. A lead screw 5 is provided in the connecting frame 2 and threadedly connected to the first electric telescopic rod 3. A motor 51 with a rotating shaft fixed to one end of the lead screw 5 is fixed in the connecting frame 2. A push plate 4 is provided on the side of the cylinder 31 away from the polishing machine body 1. A second electric telescopic rod 41 is provided in the connecting frame 2 for driving the push plate 4 to approach the cylinder 31.

[0016] like Figure 2 As shown, a movable bar 35 is slidably connected to the bottom of the connecting frame 2. The main body of the first electric telescopic rod 3 is fixed to the top of the movable bar 35. The lead screw 5 is threadedly connected to the movable bar 35. The end of the lead screw 5 away from the motor 51 is rotatably connected to a fixing plate 52 fixed to the bottom of the connecting frame 2. There are two first electric telescopic rods 3, which are symmetrically distributed front and back. The motor 51 is a servo motor. After starting the motor 51, it can drive the lead screw 5 to rotate, and the movable bar 35 can drive the first electric telescopic rod 3 to move left or right (towards...). Figure 1 (The orientation is shown in the middle), and the cylinder 31 moves accordingly; the fixed plate 52 can increase the stability of the lead screw 5.

[0017] like Figure 2 and Figure 3As shown, the telescopic end of the first electric telescopic rod 3 is fixed with a connecting rod 33, and the top of the connecting rod 33 is fixed to the bottom of the cylinder 31; a lifting plate 43 is slidably connected to the side of the connecting frame 2 away from the grinding machine body 1; the fixed end of the second electric telescopic rod 41 is fixed to the inside of the lifting plate 43; a third electric telescopic rod 44, whose telescopic end is connected to the bottom of the lifting plate 43, is fixed to one side of the connecting frame 2; a battery 34 is fixed on the connecting rod 33. After starting the first electric telescopic rod 3, the telescopic end of the first electric telescopic rod 3 can drive the cylinder 31 to move up or down through the connecting rod 33. After starting the third electric telescopic rod 44, the telescopic end of the third electric telescopic rod 44 can drive the lifting plate 43 to move the second electric telescopic rod 41 up or down. When the push plate 4 and the cylinder 31 fix the umbrella handle, the first electric telescopic rod 3 and the third electric telescopic rod 44 can be started, so that the cylinder 31 and the push plate 4 can move the umbrella handle upward. At this time, the end of the umbrella handle that was previously located in the limiting sleeve inside the grinding machine body 1 corresponds to the movable grinding roller inside the grinding machine body 1. The motor 51 starts to rotate the lead screw 5. At the same time, the telescopic end of the second electric telescopic rod 41 extends, so that the cylinder 31 and the push plate 4 move towards the grinding machine body 1 in sync, so that the end of the umbrella handle contacts the movable grinding roller inside the grinding machine body 1, and the end of the umbrella handle is ground.

[0018] like Figure 2 and Figure 3 As shown, a rubber pad 42 is fixed to the side of the push plate 4 near the cylinder 31, and a rubber ring 32 is fitted on the outer wall of the cylinder 31 for fixed connection. The rubber pad 42 and the rubber ring 32 can increase the friction between the push plate 4, the cylinder 31 and the umbrella handle, and increase the firmness of the cylinder 31 in fixing the umbrella handle after cooperating with the push plate 4.

[0019] like Figure 2 and Figure 3As shown, a feeding plate 7 located below the cylinder 31 is fixed inside the connecting frame 2. A feeding port 8 corresponding to the feeding plate 7 is opened on the side of the connecting frame 2 away from the grinding machine body 1. The side of the feeding plate 7 near the feeding port 8 is lower than the other side. A connecting seat 6 is fixed inside the cylinder 31 by bolts. A No. 4 electric telescopic rod 61 is fixed on the side of the connecting seat 6 away from the grinding machine body 1. A connecting plate 62 is fixed to the telescopic end of the No. 4 electric telescopic rod 61. A moving plate 63 is fixed on the other side of the connecting plate 62 by bolts. An opening for the moving plate 63 to pass through is opened on the side of the cylinder 31 away from the grinding machine body 1. When the push plate 4 and the cylinder 31 fix the umbrella handle and the umbrella handle is polished, the umbrella handle is moved into the connecting frame 2. Then, as the push plate 4 moves away from the umbrella handle, the fourth electric telescopic rod 61 is activated, causing the connecting plate 62 to move the moving plate 63 toward the push plate 4. After the umbrella handle is moved away from the polishing machine body 1, the moving plate 63 returns to its original position, and the umbrella handle falls down onto the feeding plate 7. Then, it slides through the feeding plate 7 toward the feeding port 8 and is discharged into the external collection box outside the connecting frame 2, completing the automatic feeding of the umbrella handle. The battery 34 can supply power to the fourth electric telescopic rod 61, and the second electric telescopic rod 41 can be a three-section electric telescopic rod.

[0020] like Figure 2 and Figure 3 As shown, a rubber block 64 is fixed to the side of the movable plate 63 away from the connecting plate 62, and a through hole adapted to the rubber block 64 is provided on the rubber ring 32. The rubber block 64 can increase the friction between the movable plate 63 and the umbrella handle, better push the umbrella handle to move, and can form a complete ring with the rubber ring 32 to better fix the umbrella handle.

[0021] like Figure 2 As shown, a sponge pad 71 is fixed to the top surface of the feed plate 7. The sponge pad 71 can reduce the friction when the umbrella handle falls onto the feed plate 7, thus protecting the umbrella handle.

[0022] In use, the limit bolts on the grinding machine body 1 used to control the lifting and lowering of the movable block can be replaced with an automatic telescopic rod 9. The fixed end of the automatic telescopic rod 9 is fixed to the top of the grinding machine body 1, and the telescopic end of the automatic telescopic rod 9 is fixed to the top of the movable block. After starting the automatic telescopic rod 9, the movable block can drive the movable grinding roller to move up or down without manual operation by the operator (the grinding machine body 1 is the umbrella handle grinding device described in the background art, therefore, the grinding machine body 1 is prior art and will not be described in detail here); when the end of the umbrella handle away from the arc-shaped part is stuck... After the umbrella handle is inserted into the limiting sleeve inside the grinding machine body 1 (a funnel-shaped rubber cylinder can be fixed inside the limiting sleeve, and the end of the umbrella handle is inserted into the rubber cylinder to complete the fixation of the umbrella handle), the curved part of the umbrella handle (the part near the connecting frame 2) is ground. After the curved part of the umbrella handle is ground, the umbrella handle is pushed towards the connecting frame 2, so that the straight part of the umbrella handle is ground. When the curved part of the umbrella handle enters the connecting frame 2 and is located between the push plate 4 and the cylinder 31, the first electric telescopic rod 3 can be activated to drive the cylinder 31 to move upward, so that the cylinder 3... The top of 1 contacts the straight part of the umbrella handle; when the umbrella handle is polished, as the limiting sleeve inside the polishing machine body 1 moves towards the inside of the polishing machine body 1, the second electric telescopic rod 41 is activated, causing the push plate 4 to move towards the cylinder 31. When the cylinder 31 is located inside the arc-shaped part of the umbrella handle (the diameter of the rubber ring 32 on the cylinder 31 is the same as the diameter of the fixed polishing roller inside the polishing machine body 1), as the limiting sleeve continues to move, the end of the umbrella handle can be separated from the limiting sleeve. The cylinder 31, in conjunction with the push plate 4, can then complete the fixation of the umbrella handle; then start After the motor 51 rotates the lead screw 5, it simultaneously starts the second electric telescopic rod 41. The cylinder 31 and the push plate 4 move synchronously away from the grinding machine body 1, so that the part of the umbrella handle that was previously located in the limiting sleeve passes between the movable grinding roller and the fixed grinding roller in the grinding machine body 1, completing the all-round grinding operation of the umbrella handle and completing the automatic unloading of the umbrella handle, so that the umbrella handle enters the connecting frame 2, which makes it easy for the staff to quickly fix the umbrella handle to be ground. When the subsequent umbrella handles are being ground, the staff can collect the ground umbrella handles.
