Description

Technical Field

[0001] This utility model relates to the field of glass production technology, specifically to a glass production trimming device. Background Technology

[0002] Glass is an amorphous inorganic non-metallic material. It is generally made from a variety of inorganic minerals (quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, and soda ash) as the main raw materials, with the addition of small amounts of auxiliary materials. The main components of glass are silicon dioxide and other oxides, primarily silicate complex salts; it is an amorphous solid with an irregular structure. During the production of glass discs, a whole piece of glass is cut into discs. However, the outer wall of the cut glass discs is not smooth and requires edge trimming. When manually trimming the glass discs using trimming devices, the discs need to be constantly rotated, which is time-consuming, labor-intensive, and inefficient. Furthermore, trimming generates a large number of small glass fragments that can be inhaled by workers, causing harm.

[0003] Chinese patent discloses a glass trimming device (authorization announcement number CN214270681U). The patented technology has a support foot installed at the bottom of the workbench. The left side wall of the workbench is hinged to a stabilizing sleeve through a hinge frame and a hinge shaft. A rotating shaft is installed inside the stabilizing sleeve. A helical gear two is installed at the lower end of the rotating shaft. A trimming cutter is installed at the upper end of the rotating shaft through a clamp. A protective cover is provided on the outside of the trimming cutter. The lower end of the protective cover is connected to the lower end of the stabilizing sleeve. An installation groove is opened on the upper side of the protective cover. A nozzle is installed in the installation groove. The helical gear two is set in the installation shell and meshes with the helical gear one. A motor is installed on the side wall of the installation shell. The lower end of the adjuster is hinged to the side wall of the support foot.

[0004] However, this patent still has shortcomings. During glass tray production, the entire piece of glass is cut into trays, but the outer wall of the cut trays is not smooth and requires edge trimming. When manually trimming the glass trays using an edge trimming device, the tray needs to be constantly rotated, which is time-consuming, labor-intensive, and inefficient. Furthermore, the trimming process generates a large number of small glass shards that can be inhaled by workers, causing harm. Therefore, those skilled in the art have provided a glass production edge trimming device to solve the problems mentioned in the background art. Utility Model Content

Detailed Implementation

[0021] 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.

[0022] Please see Figures 1 to 5 The present invention provides two embodiments:

[0023] Example 1: A glass production trimming device, including a base plate 1 and a glass tray 24. Support plates 1 and 2 are fixed on both sides of the upper surface of the base plate 1. Support plate 2 and 3 are fixed on the upper surface of the support plate 1 and 3. A circular box 4 is fixed on one side of the support plate 2 and 3. A threaded groove 5 is opened at the front end of the circular box 4. A circular groove 23 is opened at the rear end of the inner wall of the threaded groove 5. A threaded rod 10 is threadedly connected to the rear end of the inner wall of the circular groove 23. The front end of the threaded rod 10 is rotatably connected to a turntable 25. A threaded cap 8 is threadedly connected to the inner wall of the threaded groove 5. The rear end of the threaded cap 8 is rotatably connected to a turntable 19. The glass tray 24 is placed between the turntable 19 and the turntable 25. A through groove 22 is opened at the top of the circular box 4. A fixing plate 7 is fixed on the upper surface of the circular box 4. A long groove 16 is opened on one side of the fixing plate 7. A connecting block 14 is inserted into the long groove 16. A movable frame 6 is fixed on one side of the connecting block 14. A polishing block 11 is fixed at the bottom end of the movable frame 6. A feeding pipe 18 is fixed at the bottom end of the circular box 4. A flexible hose 27 is sleeved inside the feeding pipe 18.

[0024] The rear end of the round box 4 has a threaded hole 26, and the front end of the threaded rod 10 passes through the threaded hole 26 and is threadedly connected.

[0025] The threaded cover 8 has a round hole 21 at the front end, and a motor 20 is fixed at the front end of the threaded cover 8. The rear end of the drive shaft of the motor 20 extends into the round hole 21. A turntable 19 is fixed at the rear end of the drive shaft of the motor 20. Handles 9 are fixed on both sides of the front end of the threaded cover 8.

[0026] The motor 20 mainly consists of a stator and a rotor. The stator includes the stator core, stator windings, and frame. When three-phase alternating current is applied to the stator windings, a rotating magnetic field is generated. The rotor includes the rotor core and rotor windings. The rotor windings cut magnetic lines of force in the rotating magnetic field to generate induced current, which in turn produces electromagnetic torque to make the motor rotate.

[0027] The inner wall of the circular groove 23 is connected to four rotating rollers 28 in a ring array.

[0028] The upper surface of the connecting block 14 is provided with a threaded hole 15, the upper surface of the fixing plate 7 is provided with a round hole 13, the upper surface of the fixing plate 7 is fixed with a motor 12, the bottom end of the drive shaft of the motor 12 extends into the round hole 13, the bottom end of the drive shaft of the motor 12 is fixed with a threaded rod 17, the bottom end of the threaded rod 17 passes through the threaded hole 15 and is threadedly connected.

[0029] The motor 12 is a servo motor. The servo motor can rotate forward and backward as needed, so that the polishing block 11 can move up and down as needed, which makes it easier for the polishing block 11 to trim and polish the glass disk 24.

[0030] The working principle of a servo motor mainly involves converting the input voltage signal into angular displacement or angular velocity output on the motor shaft. Servo motors are commonly used as actuators in automatic control systems to achieve precise position and speed control. Their core function is that once a control voltage is applied, the rotor immediately begins to rotate, and when the control voltage disappears, the rotor quickly stops. The direction and speed of rotation of the shaft depend entirely on the direction and magnitude of the control voltage.

[0031] The structure of a servo motor mainly includes the following parts:

[0032] Stator and rotor: The stator core is typically made of layers of laminated silicon steel sheets with slots on its surface for embedding two-phase excitation windings and control windings. These two windings are spatially offset by 90° electrical degrees. In operation, the excitation winding is connected to an AC excitation power supply, while the control winding is supplied with a control signal voltage.

[0033] Control circuit: Responsible for receiving and processing input signals from the external controller, which tell the servo system where to move, at what speed, or in what direction. The control circuit sends power to the motor to drive it.

[0034] Feedback device: This is typically a potentiometer or encoder that measures the current position of the output shaft. The feedback device forwards the position data back to the control circuit, which then adjusts the motor power to align the actual position with the desired position in the input signal.

[0035] In this embodiment, the glass disk 24 needs to be inserted into the circular groove 23, and the outer wall of the glass disk 24 needs to contact the rotating roller 28. The threaded rod 10 is rotated so that the turntable 25 fits against the rear end of the glass disk 24. The operator holds the handle 9 and inserts the threaded cover 8 into the threaded groove 5 and connects it with threads. The turntable 19 fits against the front end of the glass disk 24. Then the motor 20 is started so that the glass disk 24 rotates. At the same time, the motor 12 is started so that the threaded rod 17 rotates. The connecting block 14, the moving frame 6 and the polishing block 11 move. The polishing block 11 contacts the rotating glass disk 24 to trim and polish the edges, which saves time and effort and improves work efficiency.

[0036] Example 2:

[0037] The bottom of the round box 4 has a mounting hole 29, and the upper end of the outer wall of the feeding pipe 18 extends into the mounting hole 29 and is fixed.

[0038] The through groove 22 at the top of the round box 4 is vertically aligned with the center of the polishing block 11, and the through groove 22 at the top of the round box 4 is vertically aligned with the center of the glass plate 24.

[0039] The through groove 22, the polishing block 11 and the glass disk 24 are vertically aligned, which makes it easy for the polishing block 11 to extend into the circular groove 23 through the through groove 22, and to facilitate the polishing block 11 to contact the glass disk 24 for edge trimming and polishing.

[0040] In this embodiment, after the glass plate 24 is trimmed and polished, small glass fragments will be generated during the trimming and polishing process. The hose 27 is connected to the vacuum cleaner, and the electric valve connected to the outer wall of the feed pipe 18 is activated, opening the feed pipe 18. The vacuum cleaner can clean and collect the small glass fragments in the circular groove 23 to prevent the small glass fragments from flying and being inhaled by the staff, causing health damage to the staff.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
