Description

Technical Field

[0001] This utility model relates to the technical field of luggage handle polishing equipment, specifically a luggage handle surface polishing equipment. Background Technology

[0002] A suitcase, also known as a travel case or rolling suitcase, is a box used to carry belongings when traveling; it is a type of luggage. Suitcases are typically used to store clothing, personal care items, and souvenirs needed for a trip. Generally, suitcases can be categorized by material into soft fabric suitcases and hard-sided suitcases (hard-sided suitcases can be further divided into ABS and PP). They can also be categorized by construction into upright rolling suitcases and horizontal wardrobe suitcases. Many bags are made of genuine leather, and the most important aspect of leather goods is quality.

[0003] In the production process of suitcases, the pull rod is an important structure that bears the responsibility of pulling and bearing force on the suitcase. At the same time, for aesthetic purposes, the pull rod needs to be polished to remove burrs and beautify it. Polishing equipment is usually used. However, traditional polishing equipment cannot polish pull rods of different diameters and is prone to generating fine dust during polishing, which threatens the working environment. Based on this, a surface polishing equipment for suitcase pull rods is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a surface polishing device for luggage handles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a luggage handle surface polishing device, comprising a support plate, the top of which has three sliding grooves, each groove containing two sliding blocks, each sliding block containing a rotating rod, one end of which is fixedly mounted with a turntable, the outer side of which is provided with a bidirectional thread, the top of each sliding block containing a clamping plate, the top of which has several positioning holes, the top of which is movably mounted with a limit plate, the support plate containing an installation groove, and the installation groove containing a support fixedly mounted. The support ring frame has two supporting bearings fitted inside. A rotating ring is fitted inside each of the two supporting bearings. The rotating ring has several ventilation holes inside and several polishing bristles fixedly installed on its inner side. A driven gear ring is fixedly installed on one side of the rotating ring. A limit groove is formed on the outer side of the support ring frame. A driving gear meshes with the outer side of the driven gear ring. A servo motor is driven to one side of the driving gear. An air extraction pipe is connected to the top of the support ring frame. A dust filter is connected to the other end of the air extraction pipe. An air pump is connected to the output end of the dust filter.

[0006] Preferably, the rotating rod is connected to the internal thread of the slider via a bidirectional thread and movably passes through the slider. The rotating rod movably passes through the slide groove via a bearing and extends to the outside of the support plate.

[0007] Preferably, the positioning holes are linearly and evenly distributed on the top of the clamping plate, and the limiting plate is fixed to the top of the clamping plate by bolts passing through the positioning holes.

[0008] Preferably, the vent holes are evenly distributed in a circumferential linear pattern inside the rotating ring, the polishing bristles are evenly distributed in a circumferential linear pattern inside the rotating ring, and the polishing bristles and vent holes are linearly staggered inside the rotating ring.

[0009] Preferably, the servo motor is fixedly mounted on the top of the support plate, and the driving gear extends through the limiting groove to the inner side of the support ring frame and meshes with the driven gear ring.

[0010] Preferably, both the dust filter and the air pump are fixedly installed on the top of the support plate, and the input end of the air pump is connected to the output end of the dust filter through a pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: When the device is in use, the turntable is first rotated to make the rotating rod rotate. Then, the rod is connected to the slider through a bidirectional thread, so that the two sliders move closer and further apart in the same rotation direction. This adjusts the distance between the clamping plates, thereby causing the clamping plates to hold the pull rod that needs to be polished. During operation, the servo motor and the air pump are started. The servo motor rotates, which drives the drive gear to rotate, which in turn drives the meshing driven gear ring to rotate, which in turn drives the rotating ring to rotate, thereby causing the polishing brush to rotate. When the operator pushes the pull rod to move, the polishing brush performs circumferential polishing on the outer surface of the pull rod, avoiding the four corners. Through the sliding clamping of the pull rod by the clamping plates, pull rods of different sizes can be clamped and pushed. The overall use effect is good, and the polishing operation is more convenient.

[0012] This invention uses an air pump to draw air from the dust filter and then directs the airflow from inside the support ring frame through the air extraction pipe. During polishing, debris is generated and blown around. The airflow is guided through the vent holes and the gap between the rotating ring and the support ring frame, causing the airflow to carry dust out. The dust filter then filters the debris and dust in the airflow, reducing the amount of dust and debris flying around during polishing operations, increasing the cleanliness of the environment, and indirectly increasing safety.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a luggage handle surface polishing device, including a support plate 1, the top of the support plate 1 having three sliding grooves 3, each of the three sliding grooves 3 having two sliders 9 slidably installed inside, each slider 9 having a rotating rod 2 sleeved inside, one end of the rotating rod 2 having a turntable 7 fixedly installed, the outer side of the rotating rod 2 having a bidirectional thread 8, each slider 9 having a clamping plate 4 fixedly installed on its top, the clamping plate 4 having several positioning holes 5, the clamping plate 4 having a limit plate 6 movably installed on its top, the support plate 1 having an installation groove 22 inside, the installation groove 22 having a support ring frame 15 fixedly installed inside, the support ring frame 15 having a ... Two support bearings 20 are sleeved together, and a rotating ring 16 is sleeved on the inner side of the two support bearings 20. Several ventilation holes 18 are opened inside the rotating ring 16. Several polishing bristles 17 are fixedly installed on the inner side of the rotating ring 16. A driven gear ring 19 is fixedly installed on one side of the rotating ring 16. A limit groove 21 is opened on the outer side of the support ring frame 15. A drive gear 14 meshes on the outer side of the driven gear ring 19. A servo motor 13 is driven and connected to one side of the drive gear 14. An air extraction pipe 12 is connected to the top of the support ring frame 15. The other end of the air extraction pipe 12 is connected to a dust filter 10. The output end of the dust filter 10 is connected to an air pump 11.

[0020] The working principle of the above technical solution is as follows: In use, firstly, the turntable 7 is rotated, causing the rotating rod 2 to rotate. Then, it is threadedly connected to the slider 9 through the bidirectional thread 8, causing the two sliders 9 to move closer and further apart in the same rotation direction. This adjusts the distance between the clamping plates 4, causing the clamping plates 4 to clamp the pull rod that needs to be polished. During operation, the servo motor 13 and the air pump 11 are started. The rotation of the servo motor 13 drives the drive gear 14 to rotate, which in turn drives the meshing driven gear ring 19 to rotate, which in turn drives the rotating ring 16 to rotate, thereby causing the polishing brush bristles 17 to rotate. When the operator pushes the pull rod to move, the polishing brush bristles 17 perform circumferential polishing on the outer surface of the pull rod, avoiding the four corners. Through the sliding clamping of the pull rod by the clamping plates 4, pull rods of different sizes can be clamped and pushed. The overall use effect is good, and the polishing operation is relatively convenient.

[0021] In another implementation scheme, such as Figures 1-4 As shown, the rotating rod 2 is connected to the internal thread of the slider 9 through the bidirectional thread 8 and moves through the slider 9. The rotating rod 2 moves through the slide groove 3 through the bearing and extends to the outside of the support plate 1.

[0022] The bidirectional thread 8 is symmetrically distributed at both ends of the rotating rod 2, which facilitates the reverse transmission of force when connected with the two sliders 9 by the thread. When the rotating rod 2 rotates in one direction, the two sliders 9 move towards and away from each other under the action of the symmetrical bidirectional thread 8, which facilitates rotation adjustment. In addition, the turntable 7 has multiple holes inside, which facilitates the insertion of bolts to fix the turntable 7 to the outside of the support plate 1, which is convenient for long-term operation after adjustment, stabilizes the spacing of the clamping plates 4, prevents loosening during adjustment, and increases stability.

[0023] In another implementation scheme, such as Figures 1-4 As shown, the positioning holes 5 are linearly and evenly distributed on the top of the clamping plate 4, and the limiting plate 6 is fixed to the top of the clamping plate 4 by bolts passing through the positioning holes 5.

[0024] The positioning hole 5 provides a fixing point for the limiting plate 6, which facilitates the insertion of bolts into the interior of the positioning hole 5 to fix the limiting plate 6 and adjust the position of the limiting plate 6 to limit the top of the pull rod of different lengths, which is convenient for pushing operations. There are multiple limiting plates 6, and the length of the multiple limiting plates 6 has many different sizes. Each size is suitable for limiting the pull rod of different specifications, which is convenient for limiting the top of the pull rod.

[0025] In another implementation scheme, such as Figures 1-4 As shown, the vent holes 18 are evenly distributed in a circular linear pattern inside the rotating ring 16, and the polishing bristles 17 are evenly distributed in a circular linear pattern inside the rotating ring 16. The polishing bristles 17 and the vent holes 18 are linearly interspersed inside the rotating ring 16.

[0026] The vent 18 facilitates airflow guidance and extraction. The uniform distribution of the polishing bristles 17 facilitates uniform polishing and grinding of the pull rod, and promotes stable operation. The center point of the polishing bristles 17 and the support ring frame 15 corresponds to the center position of the inner side of the clamping plate 4.

[0027] In another implementation scheme, such as Figures 1-4 As shown, the servo motor 13 is fixedly installed on the top of the support plate 1, and the driving gear 14 extends through the limiting groove 21 to the inner side of the support ring frame 15 and meshes with the driven gear ring 19.

[0028] After the servo motor 13 is fixed, it drives the drive gear 14 to rotate, which in turn drives the meshing driven gear ring 19 to rotate. The drive gear 14 is driven by the driven gear ring 19 through the limiting groove 21, which facilitates the transmission operation. The specifications, dimensions and positions of the limiting groove 21, the driven gear ring 19 and the drive gear 14 are all corresponding.

[0029] In another implementation scheme, such as Figures 1-3 As shown, the dust filter 10 and the air pump 11 are both fixedly installed on the top of the support plate 1, and the input end of the air pump 11 is connected to the output end of the dust filter 10 through a pipe.

[0030] This solution uses an air pump 11 to extract air from the dust filter 10, and then uses an air extraction pipe 12 to guide the airflow inside the support ring frame 15. During polishing, debris is generated and blown around. The airflow is guided through the vent 18 and the gap between the rotating ring 16 and the support ring frame 15, causing the airflow to carry dust out. The dust filter 10 filters the debris and dust in the airflow, which helps to reduce the blowing of dust and debris during polishing operations, increases the cleanliness of the environment, and indirectly increases safety.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
