[0002] Metal parts typically require polishing during processing to achieve a more aesthetically pleasing final appearance. A Chinese patent application (application number 202222992844.1) discloses a forming and polishing mechanism for handle processing, comprising a polishing cylinder with a magnetic cavity inside. A central column is vertically mounted inside the magnetic cavity, and multiple aeration ports are formed on the bottom surface of the central column. A stirring motor is fixedly mounted at the bottom center of the polishing cylinder, and a permanent magnet turntable is driven to the top of the stirring motor. A water pump and an ultrasonic generator are mounted in a circular array on the side of the stirring motor, and an aerator is mounted on top of the ultrasonic generator. A base box is mounted on the bottom side of the polishing cylinder, and a draining mechanism is mounted on one side of the top of the polishing cylinder.

[0003] The above-mentioned technology makes it inconvenient to quickly retrieve the polished workpiece, which affects production efficiency and is therefore detrimental to the production and sales of handles. Therefore, in order to solve the above-mentioned technical problems, we propose a forming and polishing mechanism for handle processing. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a forming and polishing mechanism for handle processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A forming and polishing mechanism for handle processing includes a base, a processing cylinder at the upper end of the base, a vibration motor installed at the bottom of the processing cylinder and inside the base, a rotating cover rotatably mounted inside the processing cylinder via a rotating assembly, a sieve hole at the bottom of the rotating cover, an automatic opening and closing door at the end of the rotating cover away from the rotating assembly, the upper end of the automatic opening and closing door being hinged to the rotating cover, the outer wall of the automatic opening and closing door being in contact with the inner wall of the processing cylinder, a corresponding discharge port on one side of the outer wall of the processing cylinder corresponding to the automatic opening and closing door, and an air extraction assembly at the discharge port, and a cylindrical feeding hopper installed on the other side of the outer wall of the processing cylinder.

[0007] Preferably, the exhaust assembly includes a feeding pipe, a finished product box, and an exhaust fan. The upper and lower ends of the feeding pipe are connected to the discharge port of the processing cylinder and the finished product box, respectively. The exhaust end of the exhaust fan is connected to the finished product box, and the output end of the exhaust fan is connected to an external dust filtration facility through an exhaust pipe.

[0008] Preferably, the feeding pipe consists of a rigid feeding hopper and a flexible guide pipe. The lower end of the feeding hopper is connected to the upper end of the guide pipe. The upper end of the feeding hopper is installed outside the discharge port of the processing cylinder, and the lower end of the guide pipe is installed on the upper side of the finished product box.

[0009] Preferably, the rotating assembly includes a geared motor and a pin. The pin is rotatably mounted in the middle of the processing cylinder, the geared motor is mounted on one side of the processing cylinder and connected to the end of the pin, and the middle of the pin is connected to the rotating cover.

[0010] Preferably, the upper end of the feeding hopper is hinged with a sealing cover, and a one-way valve is installed in the middle of the sealing cover.

[0011] Preferably, the upper surface of the feeding hopper is provided with an annular magnetic strip, and the cover of the sealing cover away from the hinge is in contact with the feeding hopper through the magnetic strip.

[0012] Preferably, a plurality of magnetic columns are installed on the back side of the rotating cover, and an observation cover is provided on the upper side of the processing cylinder.

[0013] The forming and polishing mechanism for handle processing proposed in this utility model has the following advantages:

[0014] 1. In this utility model, when the automatic opening and closing door at the end of the rotating cover is fully in the opening of the hopper, the polished handle inside the rotating cover slides down its bottom wall and enters the hopper for discharge after the automatic opening and closing door is opened. As the rotating cover continues to move, the automatic opening and closing door automatically adheres to the end of the rotating cover under the action of the inner wall of the processing cylinder. Thus, when using this solution, personnel only need to load the material. Subsequently, the polished handle can be automatically retrieved, and the residual polishing medium on its surface can be automatically shaken off after retrieval. This reduces the workload of manual cleaning of the residual polishing medium on the surface of the handle, thereby improving the convenience and production efficiency of the polishing mechanism proposed in this solution.

[0015] 2. The air extraction component in this invention helps to prevent turbid air from leaking to the outside of the processing cylinder and causing adverse effects on the external environment and personnel. The sealing cover and one-way valve help to prevent turbid air inside the processing cylinder from leaking from the feeding hopper, and also allow fresh air from the outside to enter the processing cylinder from here to replace the turbid air inside the processing cylinder, so as to prevent personnel from inhaling turbid air and causing discomfort when feeding materials. The magnetic strip helps to fix the sealing cover to prevent it from opening automatically when the vibration motor is running. The magnetic column helps to collect the metal powder generated during the polishing process when the rotating cover is rotating. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example

[0024] Reference Figure 1-6 A forming and polishing mechanism for handle processing includes a base 1, a processing cylinder 2 at the upper end of the base 1, a vibration motor 3 installed at the bottom of the processing cylinder 2 and inside the base 1, a rotating cover 4 rotatably mounted inside the processing cylinder 2 via a rotating assembly, a sieve hole at the bottom of the rotating cover 4, an automatic opening and closing door 5 at the end of the rotating cover 4 away from the rotating assembly, the upper end of the automatic opening and closing door 5 is hinged to the rotating cover 4, the outer wall of the automatic opening and closing door 5 is in contact with the inner wall of the processing cylinder 2, a corresponding discharge port is provided on one side of the outer wall of the processing cylinder 2 corresponding to the automatic opening and closing door 5, and an air extraction assembly is provided at the discharge port, and a cylindrical feeding hopper 6 is installed on the other side of the outer wall of the processing cylinder 2. Example

[0025] Reference Figure 1-6 While all other parts are the same as in Example 1, the difference between this example and Example 1 is that:

[0026] The exhaust assembly includes a feeding pipe 7, a finished product box 8, and an exhaust fan 9. The upper and lower ends of the feeding pipe 7 are connected to the discharge port of the processing cylinder 2 and the finished product box 8, respectively. The exhaust end of the exhaust fan 9 is connected to the finished product box 8, and the output end of the exhaust fan 9 is connected to an external dust filter through an exhaust pipe. The exhaust assembly is designed to ensure that when polishing the handles in this solution, the turbid air generated inside the processing cylinder 2 is extracted by the exhaust fan 9 and sent to the external dust filter for purification through the exhaust pipe. To prevent turbid air from leaking to the outside of the processing cylinder 2 and causing adverse effects on the external environment and personnel; the feeding pipe 7 consists of a rigid feeding hopper 701 and a flexible guide pipe 702. The lower end of the feeding hopper 701 is connected to the upper end of the guide pipe 702. The upper end of the feeding hopper 701 is installed outside the discharge port of the processing cylinder 2, and the lower end of the guide pipe 702 is installed on the upper side of the finished product box 8. The setting of the guide pipe 702 prevents the finished product box 8 from vibrating synchronously when the processing cylinder 2 vibrates.

[0027] The rotating assembly includes a geared motor 10 and a pin. The pin is rotatably mounted in the middle of the processing cylinder 2. The geared motor 10 is mounted on one side of the processing cylinder 2 and connected to the end of the pin. The middle of the pin is connected to the rotating cover 4. The rotating assembly facilitates stable rotation of the rotating cover 4, thereby facilitating control of the rotating cover 4 for handle retrieval and automatic material discharge. A sealing cover 11 is hinged to the upper end of the feeding hopper 6. A one-way valve is installed in the middle of the sealing cover 11. The sealing cover 11 and the one-way valve prevent turbid air inside the processing cylinder 2 from leaking out of the feeding hopper 6, while also allowing fresh air from the outside to enter the processing cylinder 2 from here, thus purifying the interior of the processing cylinder 2. The turbid air is replaced to prevent personnel from inhaling turbid air and causing discomfort during subsequent feeding. The upper surface of the feeding hopper 6 is provided with an annular magnetic strip 12. The cover of the sealing cover 11 away from the hinge is in contact with the feeding hopper 6 through the magnetic strip 12. The setting of the magnetic strip 12 makes it easy to fix the sealing cover 11 to prevent the sealing cover 11 from opening automatically when the vibration motor 3 is running. Several magnetic columns 13 are installed on the back side of the rotating cover 4. An observation cover 14 is provided on the upper side of the processing cylinder 2. The setting of the observation cover 14 makes it easy for personnel to handle the polishing status inside the cylinder 2, while the setting of the magnetic columns 13 makes it easy to collect the metal powder generated during the polishing process when the rotating cover 4 rotates.

[0028] Operating Principle and Advantages: In use, the polishing medium is placed at the bottom of the processing cylinder 2. Then, the handle to be polished is placed inside the processing cylinder 2. The vibrating motor 3 then drives the polishing medium and the handle inside the processing cylinder 2 to vibrate, thus polishing the handle through friction between the polishing medium and the handle. Meanwhile, the reduction motor 10 drives the rotating cover 4 to rotate clockwise. During this rotation, the rotating cover 4 picks up the polishing medium and the handle until it reaches the discharge hopper 701. During this process, the polishing medium flows back to the bottom of the processing cylinder 2 through the sieve holes at the bottom of the rotating cover 4. Then, the operator adds... When a new batch of handles is inserted, the vibration motor 3 polishes the new batch of handles while also driving the rotating cover 4 to vibrate. This allows the polishing medium remaining inside the rotating cover 4 to flow back into the processing cylinder 2. After the new batch of handles is polished, the reduction motor 10 continues to drive the rotating cover 4 to rotate until the automatic opening and closing door 5 at the end of the rotating cover 4 is completely in the opening of the hopper 701. At this time, the polished handles inside the rotating cover 4 slide down its bottom wall and enter the hopper 701 after opening the automatic opening and closing door 5. As the rotating cover 4 continues to move, its automatic opening and closing door 5 automatically adheres to the end of the rotating cover 4 under the action of the inner wall of the processing cylinder 2.

[0029] It should be further explained that the exhaust assembly is designed to ensure that the turbid air generated inside the processing cylinder 2 during the polishing of the handles is extracted by the exhaust fan 9 and sent to the external dust filter for purification through the exhaust pipe, thus preventing turbid air from leaking outside the processing cylinder 2 and causing adverse effects on the external environment and personnel. The rotating assembly facilitates the stable rotation of the rotating cover 4, thereby facilitating the control of the rotating cover 4 for handle retrieval and automatic material discharge. The sealing cover 11 and the one-way valve prevent turbid air inside the processing cylinder 2 from leaking from the feeding hopper 6, and also allow fresh air from the outside to enter the processing cylinder 2 from here to replace the turbid air inside the processing cylinder 2, preventing personnel from inhaling turbid air and causing discomfort during subsequent material feeding. The magnetic strip 12 is designed to fix the sealing cover 11 in place, preventing the sealing cover 11 from opening automatically when the vibration motor 3 is running. The magnetic column 13 is designed to collect the metal powder generated during the polishing process when the rotating cover 4 rotates.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
