Description

Technical Field

[0001] This utility model belongs to the field of standard parts screening technology, and relates to a flat pad screening device, specifically a screening device for hot-dip galvanized flat pads. Background Technology

[0002] The flat pad screening equipment includes an inclined frame and a screening component. Individual flat pads fall through the screen of the screening component, while flat pads that stick together are blocked by the screen of the screening component and then fall into the collection tray of defective products from the end of the screen.

[0003] In existing technologies, the screening assembly is supported by springs. Because the frame is tilted and the springs are vertical, spacers are placed at both ends of the springs to improve their stability. These spacers are machined with ramps at an angle opposite to the frame's tilt, creating a flat surface at the spring mounting position. However, machining these ramps is difficult and costly. Furthermore, existing screening assemblies include a vibrating motor installed in the center of the screen, resulting in uneven vibration and high noise levels. Utility Model Content

[0004] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a screening device for hot-dip galvanized flat pads, thereby reducing manufacturing costs, improving vibration uniformity, and reducing noise.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A screening device for hot-dip galvanized flat pads includes a frame, an inclined screen, a vibrating motor, and a first collection tray assembled at the end of the screen for collecting defective products. A plurality of first sleeves are fixed on the frame, and a plurality of second sleeves corresponding to the first sleeves are fixed on the screen. Springs for supporting the screen are inserted into the corresponding first and second sleeves.

[0007] The vibrating motor is provided in two parts, which are fixed on both sides of the screen and at an angle of 40° to 50° to the ground. The two vibrating motors rotate in opposite directions.

[0008] As a limitation of this utility model, a second collection tray for collecting qualified products is fixedly provided below the screen.

[0009] As another limitation of this utility model, the screen includes a support frame and a plurality of round tubes fixed in the support frame, and a gap matching the thickness of the flat pad is provided between two adjacent round tubes.

[0010] As a limitation of this utility model, each circular tube is fixed with a guide strip, and the cross-section of the guide strip is inverted V-shaped.

[0011] As a further limitation of this utility model, the angle between the two vibration motors and the ground is 45°.

[0012] As a third limitation of this utility model, the frame is fixedly provided with casters.

[0013] By adopting the above-mentioned technical solution, the beneficial effects achieved by this utility model compared with the prior art are as follows:

[0014] (1) The frame and screen of this utility model are supported by springs. During installation, one end of the spring is inserted into the first sleeve, and then the second sleeve on the screen is fitted onto the other end of the spring to realize the installation of the screen. The insertion structure makes it easier to replace screens of different sizes without other connections. Disassembly is quick and convenient. When installing the sleeve, the angle can be found and fixed at one time, which greatly reduces the manufacturing cost. The installation angle and position of the vibration motor can make the direction of the excitation force consistent with the direction of material movement, which greatly reduces noise and improves the uniformity of vibration.

[0015] (2) Both qualified and unqualified products of this utility model are collected separately through a collection tray to avoid qualified products falling directly to the ground and being inconvenient to collect;

[0016] (3) The upper end of the guide strip of this utility model is ribbed, which enables the flat pad to quickly enter the gap between the round tubes and improves the screening efficiency.

[0017] (4) The present invention is equipped with casters, which makes it easy to move the device to the required position and improves the convenience of use.

[0018] In summary, this invention can reduce manufacturing costs, improve vibration uniformity, and reduce vibration noise, making it suitable for screening standard parts. Attached Figure Description

[0024] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0025] Example: A screening device for hot-dip galvanized flat pads

[0026] like Figure 1 , Figure 2 As shown, the system includes a frame 1, a screen 4, a vibrating motor 10, a first collecting tray 8, and a second collecting tray 9. The frame 1 is inclined, and the screen 4 is parallel to the top of the frame 1. There are two vibrating motors 10, which are fixed on both sides of the screen 4 respectively. The first collecting tray 8 is fixed below the screen 4, and the second collecting tray 9 is fixed at the lower end of the screen 4. The flat pads to be screened are placed on the screen 4. Under the vibration of the vibrating motor 10, the individual pads fall onto the first collecting tray 8, and the pads that stick together fall onto the second collecting tray 9, thereby achieving the purpose of screening.

[0027] The frame 1 is a frame structure with casters 11 fixed at the four corners. The upper part of the frame 1 is an inclined surface. Four channel steels are welded to the upper part of the frame 1, located at the front, back, left and right of the frame 1 respectively. The four channel steels are horizontally arranged, and a first sleeve 2 is welded to each channel steel. The first sleeve 2 is cylindrical, and a spring 3 is inserted into each first sleeve 2. The spring 3 is made of wire with a diameter of 8mm, a length of 180mm, and an outer diameter of 90mm. The inner diameter of the first sleeve 2 matches the outer diameter of the spring 3, and the inner diameter is 95mm.

[0028] The screen 4 includes a support frame 41 and several circular tubes 42 fixed inside the support frame 41. The length direction of the circular tubes 42 is the same as the length direction of the support frame 41. A gap matching the thickness of the flat pad is provided between two adjacent circular tubes 42. In this embodiment, the gap is 4mm. A guide strip 5 is fixed on each circular tube 42. The cross-section of the guide strip 5 is inverted V-shaped, so that the side of the screen 4 that receives the flat pad forms a V-groove shape, which facilitates the flat pad falling into the gap of the circular tube 42. Four channel steels are welded on the support frame 41. The four channel steels are horizontally arranged and correspond to the four channel steels on the frame 1. A second sleeve 6 is fixed on each channel steel of the support frame 41. The four second sleeves 6 correspond to the four first sleeves 2. The other end of the spring 3 is inserted into the second sleeve 6, so that the spring 3 provides support and buffer for the screen 4.

[0029] like Figure 3As shown, a gap is provided between the end of the circular tube 42 and the downward-sloping end of the support frame 41, forming a discharge port 7 for the non-conforming flat pads to fall. Below the discharge port 7, a first collection tray 8 for collecting non-conforming products is provided. The first collection tray 8 is fixed to the lower part of the support frame 41, and its port is inclined to the side of the support frame 41. Below the screen 4, a second collection tray 9 for collecting qualified products is fixed. The second collection tray 9 is fixed to the lower part of the support frame 41, and its edges are all provided with guards to prevent the flat pads from falling.

[0030] In this embodiment, there are two vibration motors 10, which are fixed on both sides of the support frame 41 of the screen 4, and the angles with the ground are 40°, 45° or 50°. This embodiment uses 45°. The two vibration motors 10 rotate in opposite directions to reduce vibration noise.

[0031] This embodiment is used for screening hot-dip galvanized flat pads. Flat pads that stick together after hot-dip galvanizing are considered defective. This equipment can screen out the defective flat pads that stick together. During screening, the flat pads to be screened are placed on the screen 4. The screen 4 is vibrated by the vibrating motor 10. Individual flat pads, being thinner, fall into the second collection tray 9 through the gap between the round tubes 42. Flat pads that stick together, being thicker, cannot fall through the gap between the round tubes 42, but instead fall into the first collection tray 8 through the discharge port 7 along with the inclined screen 4. When it is necessary to screen flat pads of different thicknesses, different screens 4 can be directly replaced. The second sleeve 6 can be directly inserted into the spring 3 without any other connection, greatly increasing the convenience of use.

[0032] It should be noted that the above description is merely 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 above embodiments, those skilled in the art can still modify the technical solutions described in the above 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.
