Description

Technical Field

[0001] This utility model relates to the field of optical lens processing, and in particular to a sealing and closing structure for the door of an optical lens spin dryer. Background Technology

[0002] Optical lenses are transparent materials with one or more curved surfaces, made of optical materials such as glass or resin. After polishing, they are often assembled with eyeglass frames to make eyeglasses, used to correct the user's vision and obtain a clear field of vision. During the production and processing of optical lenses, they are generally cleaned before coating, bonding and ink coating. After cleaning, the optical lenses need to be dried.

[0003] The common drying method is to use a spin dryer to dry the lenses. The traditional spin dryer door closing structure is controlled by hinges to open and close the door. Due to the uneven torque at the front and rear of the door, the door cannot be completely sealed and the rear end will tilt slightly upward, which leads to the loss of hot air and affects the spin drying efficiency. In order to address this technical problem, this application proposes a sealing and closing structure for the door of an optical lens spin dryer. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sealing and closing structure for the door of an optical lens spin dryer. The cover can be driven to move vertically up and down by a cylinder. The sleeves and guide posts at the four corners of the connecting frame position and guide the cover, thereby opening and closing the opening of the chamber. This ensures that the forces at all positions at the bottom of the cover are balanced when closed, and there will be no gaps at the connection between the cover and the opening of the chamber, which would cause hot air to escape and thus affect the spin drying efficiency.

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

[0006] A sealing and closing structure for the door of an optical lens spin dryer includes a spin dryer body. A control box is fixedly connected to the right side of the top of the spin dryer body. A chamber opening is provided on the front side of the top of the spin dryer body. A fixed base is fixedly connected to the top of the spin dryer body. A support base is fixedly connected to the rear side of the top of the fixed base. A connecting frame is connected to the front end of the support base via a drive assembly. A first fixing bracket is fixedly connected to the top of the connecting frame. A cylinder is fixedly connected to the top of the first fixing bracket. A second fixing bracket is fixedly connected to the drive end of the cylinder. A chamber cover is fixedly connected to the bottom end of the second fixing bracket. Positioning elements are provided at the four corners of the top of the connecting frame. Slider blocks are provided at the four corners of the bottom end of the connecting frame. Guide assemblies are provided on the left and right sides of the top of the fixed base.

[0007] Furthermore, the drive assembly includes an electric push rod fixedly connected to the front end of the support base. The drive end of the electric push rod is fixedly connected to a fixing buckle. A connecting block is provided on the inner wall of the fixing buckle. The bottom end of the connecting block is located on the front side of the top of the connecting frame.

[0008] Furthermore, the outer wall of the cylinder drive end penetrates one top of the fixing frame, and the outer wall of the hatch matches the dimensions of the inner wall of the hatch opening.

[0009] Furthermore, the positioning component includes sleeves located at the four corners of the top of the connecting frame, and guide posts are slidably connected to the inner walls of the sleeves.

[0010] Furthermore, the outer walls of the guide pillars all penetrate through the four corners of the top of the connecting frame, and the bottom ends of the guide pillars are all fixedly connected to the top of the hatch.

[0011] Furthermore, the guide assembly includes guide rails fixedly connected to both the left and right sides of the top of the fixed base, and two sliders are slidably connected to the outer wall of each guide rail.

[0012] Furthermore, the top of each slider is located at the bottom of the connecting frame, and the top of each fixing seat is fixedly connected with a protective shell.

[0013] Furthermore, a nozzle is provided at the top of the spin-drying chamber corresponding to the rear side of the chamber opening, and a water supply pipe is fixedly connected to the other end of the nozzle.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the cylinder can drive the hatch cover to move vertically up and down. The sleeves and guide posts at the four corners of the connecting frame are used to position and guide the hatch cover, so as to open and close the hatch opening. This ensures that the forces at each position at the bottom of the hatch cover are balanced when closed, and there will be no gaps at the connection between the hatch cover and the hatch opening, which would cause hot air to be lost and thus affect the spin-drying efficiency.

[0016] 2. In this utility model, after the hatch is opened by the cylinder, the connecting block can be controlled by the electric push rod to move the connecting frame, so that the slider at the bottom of the connecting frame slides backward along the guide rail, thereby driving the hatch to the top of the hatch opening. This can prevent the operator from accidentally pinching their hand when picking up or putting down the lens, thus improving the safety of the device. Attached Figure Description

Detailed Implementation

[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. 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.

[0024] Reference Figure 1-4 This utility model provides an embodiment of a sealing and closing structure for the door of an optical lens spin dryer, including a spin dryer body 1, a control box 8 fixedly connected to the right side of the top of the spin dryer body 1, a chamber opening 11 opened on the front side of the top of the spin dryer body 1, a fixed seat 2 fixedly connected to the top of the spin dryer body 1, a support seat 4 fixedly connected to the rear side of the top of the fixed seat 2, a connecting frame 10 connected to the front end of the support seat 4 through a drive assembly, the drive assembly including an electric push rod 5 fixedly connected to the front end of the support seat 4, a fixed buckle 17 fixedly connected to the drive end of the electric push rod 5, a connecting block 18 provided on the inner wall of the fixed buckle 17, the bottom end of the connecting block 18 being located on the front side of the top of the connecting frame 10, a first fixed frame 9 fixedly connected to the top of the connecting frame 10, a cylinder 7 fixedly connected to the top of the first fixed frame 9, the outer wall of the drive end of the cylinder 7 penetrating the top of the first fixed frame 9, a second fixed frame 16 fixedly connected to the drive end of the cylinder 7, a chamber cover 12 fixedly connected to the bottom end of the second fixed frame 16, the outer wall of the chamber cover 12 matching the inner wall of the chamber opening 11;

[0025] Specifically, the control box 8 can control the electric push rod 5 to start, and the drive end of the electric push rod 5 drives the fixed buckle 17 to move. In conjunction with the connecting block 18, it pushes the connecting frame 10 to move, so that the slider 14 at the bottom of the connecting frame 10 slides on the guide rail 13, thereby sending the hatch cover 12 to the upper side of the hatch opening 11. Then, the cylinder 7 can drive the hatch cover 12 to descend and seal the hatch opening 11. Improving the sealing effect of the hatch opening 11 can reduce the loss of hot air. At the same time, compared with the upper and lower opening method, it can also prevent the operator from accidentally pinching their hand when picking up and putting down the lens.

[0026] Positioning components are provided at the four corners of the top of the connecting frame 10. The positioning components include sleeves 19 located at the four corners of the top of the connecting frame 10. Guide posts 20 are slidably connected to the inner walls of the sleeves 19. The outer walls of the guide posts 20 penetrate the four corners of the top of the connecting frame 10. The bottom ends of the guide posts 20 are fixedly connected to the top of the hatch cover 12. Slider blocks 14 are provided at the four corners of the bottom of the connecting frame 10. Guide components are provided on the left and right sides of the top of the fixed seat 2. The guide components include guide rails 13 fixedly connected to the left and right sides of the top of the fixed seat 2. Two sliders 14 are slidably connected to the outer walls of the guide rails 13. The top ends of the sliders 14 are located at the bottom of the connecting frame 10. Protective shells 3 are fixedly connected to the top of the fixed seat 2. A nozzle 15 is provided at the rear side of the hatch opening 11 at the top of the spin-drying chamber 1. A water pipe 6 is fixedly connected to the other end of the nozzle 15.

[0027] Specifically, when the cylinder 7 drives the fixed frame 16 to descend and move the hatch cover 12 to seal the hatch opening 11, the guide post 20 inside the sleeve 19 fixed at the four corners of the top of the connecting frame 10 will play a positioning and guiding role in the movement of the hatch cover 12. The water supply pipe 6 can inject pressurized pure water into the nozzle 15, and spray water in a fan shape through the nozzle 15 to automatically clean the inside of the spin-drying chamber 1.

[0028] Working principle: During use, the operator can control the electric push rod 5 and cylinder 7 to start through the control box 8. After the electric push rod 5 is started, its driving end can push the fixing buckle 17 to move the connecting block 18, thereby moving the connecting frame 10 forward. This causes the slider 14 at the bottom of the connecting frame 10 to slide forward on the surface of the guide rail 13 until the hatch cover 12 moves directly above the hatch opening 11. At this time, the electric push rod 5 will stop working. Then the cylinder 7 is started, and the driving end of the cylinder 7 pushes the fixing frame 16 to move the hatch cover 12 downward until the outer wall of the hatch cover 12 is tightly fitted with the inner wall of the hatch opening 11, achieving the effect of sealing the hatch opening 11, thereby preventing the loss of hot air and affecting the spin-drying efficiency. At the same time, the nozzle 15 can spray water mist into the spin-drying chamber 1 through the water supply pipe 6 to clean the inner wall of the spin-drying chamber 1.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
