Abstract
Description
Technical Field
[0001] This utility model relates to the field of spring machine material receiving technology, and in particular to a device for preventing products from falling to the ground on a spring machine. Background Technology
[0002] A spring machine is an industrial machine used to produce springs. During production, springs often break off and fly away. To prevent material loss due to this, a perimeter enclosure is typically built around the spring machine to collect the broken springs. However, this enclosure solution usually occupies a large area, is expensive, and does not fundamentally solve the potential quality risks caused by springs falling to the ground. Therefore, there is an urgent need for a compact, space-saving, and convenient material receiving device that can prevent springs from breaking off and falling to the ground. Utility Model Content
[0003] Technical objective: In order to overcome the shortcomings of the existing technology, this utility model provides a device for preventing products from falling to the ground on a spring machine.
[0004] Technical Solution: To achieve the above objectives, this utility model discloses a device for preventing products from falling to the ground on a spring machine. It is installed on the frame on the discharge side of the spring machine and includes a surrounding plate and a bottom plate. The surrounding plate and the bottom plate form a receiving cavity. The surrounding plate is semi-enclosed and includes an open end and a closed end. The open end is provided with a mounting plate connected to the spring machine, and the closed end is provided with a discharge port with a protective door. The bottom plate is inclined and connects to the discharge port at its lowest point.
[0005] Preferably, the protective door is located outside the enclosure, and the protective door is a pull-out type.
[0006] Preferably, the outer side of the enclosure is provided with symmetrically arranged slide rails on both sides of the discharge port, and the slide rails and the enclosure form a groove, and the protective door can move within the groove.
[0007] Preferably, the protective door has an L-shaped cross-section and includes a door panel that can be placed over the discharge port and a flange located at the top of the door panel that engages with the slide rail.
[0008] Preferably, the slide rail has an L-shaped or C-shaped cross-section.
[0009] Preferably, the mounting plate is provided with mounting holes for engaging with the spring mechanism, and the mounting holes are provided with intersecting large holes and small holes.
[0010] The beneficial effects of this utility model are:
[0011] 1. This device is installed on the discharge side of the spring machine. The springs produced from the discharge side of the spring machine will automatically break into the storage cavity and accumulate there. When the protective door is opened, because the bottom plate is set at an inclination, the product will flow out from the discharge port and fall into the external turnover box under the action of gravity. This device has a simple structure, occupies little space, is easy to install and operate.
[0012] 2. The protective door adopts a pull-out design, which makes it convenient for operators to open and close the protective door. The flange at the top of the protective door can act as a limit when closing. Attached Figure Description

[0021] The following is in conjunction with the appendix Figure 1 To be continued Figure 7 The principles and features of this utility model are described, and the examples given are only used to explain this utility model and are not intended to limit the scope of this utility model.
[0022] A device for preventing products from falling to the ground on a spring machine is suspended and installed on the frame on the discharge side of the spring machine 1, such as... Figures 1-3As shown, it includes a surrounding panel 2 and a bottom plate 3, which together form a storage cavity 4. Furthermore, the surrounding panel 2 is a three-sided semi-enclosed structure, and together with the bottom plate 3 below, it forms the storage cavity 4 to accommodate the springs produced by the spring machine 1.
[0023] The enclosure 2 includes an open end 5 and a closed end 6. The open end 5 is provided with an installation plate 7 connected to the spring machine 1. There are two sets of installation plates 7 arranged on the left and right sides of the open end 5. The closed end 6 is provided with a discharge port 8 with a protective door 9. The protective door 9 is located outside the enclosure 2. In order to facilitate the operator to open or close the protective door 9, the protective door 9 is opened and closed by a pull-out type.
[0024] Furthermore, such as Figures 4-6 As shown, the outer side of the enclosure 2 is provided with symmetrically arranged slide rails 10 on both sides of the discharge port 8. The slide rails 10 and the enclosure 2 form a slide groove 11. The cross-section of the slide rails 10 is L-shaped or C-shaped. In this embodiment, the cross-section of the slide rails 10 is C-shaped. The protective door 9 is adapted to the slide groove 11 and can move within the slide groove 11.
[0025] like Figure 5 As shown, the protective door 9 has an L-shaped cross-section and includes a door panel 12 that can be placed on the discharge port 8 and a flange 13 located on the top of the door panel 12 and locked with the slide rail 10. The door panel 12 can seal the discharge port 8 to prevent the production spring from leaking. The flange 13 plays a limiting role when the door panel 12 is sealed in place, preventing the protective door 9 from derailing.
[0026] In order to allow the output spring in the receiving cavity 4 to be discharged smoothly, the bottom plate 3 is inclined and its lowest point is connected to the discharge port 8.
[0027] like Figure 7 As shown, the mounting plate 7 is further provided with mounting holes 14 for engaging with the spring machine 1. The mounting holes 14 can be effectively engaged with the hooks on the discharge side of the spring machine 1. The mounting holes 14 are provided with intersecting large holes 15 and small holes 16. Through the limiting effect of the small holes 16, displacement and material drop caused by vibration can be prevented, and there is no need to configure additional fastening bolts for fixing.
[0028] The working principle of this device is as follows: A turnover box is placed below the discharge port 8 to collect the produced springs. The springs produced by the spring machine 1 break into the receiving cavity 4. When the discharge port 8 is opened by pulling out the protective door 9, the springs in the receiving cavity 4 automatically fall into the turnover box due to gravity. When the protective door 9 is closed, the receiving cavity 4 can store the springs. This device is bolted to the discharge side of the spring machine 1, has a compact structure, occupies a small area, and is used to collect the produced springs, preventing springs from breaking off and falling to the ground, causing material loss or potential quality risks.
[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
