Description

Technical Field

[0001] This utility model relates to the field of spring production technology, specifically a multi-stage screening device for spring production and processing. Background Technology

[0002] A multi-stage screening device for spring production is a device for separating and conveying finished, defective, and scrap springs after testing. Existing spring screening devices, such as the one described in announcement number CN108097609A, include a rotating mechanism, a product transport mechanism, and a collection mechanism. The rotating mechanism includes a rotary turntable, a limit guardrail, a turntable support plate, and a turntable driver. The turntable support plate has through holes for discharging defective and scrap products. The limit guardrail is installed on the turntable support plate. The rotary turntable is mounted on the turntable support plate, and the turntable driver is connected to the rotary turntable. The product transport mechanism includes an infeed conveyor belt, an outfeed conveyor belt, and an outfeed assembly. The collection mechanism includes a defective product pipe, a scrap pipe, and a collection box, with the collection box including a defective product collection box and a scrap collection box.

[0003] As shown in the above utility model, existing spring screening devices use a drop-feed method for waste and defective springs. Movable gates are installed at the connection points between the waste and defective product pipes and the turntable support plate to facilitate feeding. However, in this drop-feed method, waste and defective springs fall through the waste and defective product pipes. In this way, springs may accumulate and become entangled inside the pipes, especially at the connection points between the pipes and the turntable support plate. Even with movable gates, it is difficult to completely prevent spring blockage, thus affecting the normal operation and efficiency of the screening device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a multi-stage screening device for spring production and processing, thus solving the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage screening device for spring production and processing, comprising:

[0006] The base plate has movable connecting mechanisms at both ends, and the two movable connecting mechanisms are centrally symmetrically distributed.

[0007] A driving component is installed in the middle of the upper surface of the base plate, and the driving component is used to drive the vibrating guide component to move.

[0008] A vibrating guide is mounted on a base plate and connected to a connecting mechanism on the base plate. The vibrating guide is connected to the rotating disc of a screening device via a connecting pipe.

[0009] Preferably, the connecting mechanism on the base plate includes a dovetail groove formed on the upper surface of the base plate, and fixing protrusions are provided on both sides of one end of the dovetail groove.

[0010] Preferably, the driving component includes a mounting plate fixed to the middle of the upper surface of the base plate, a motor fixed to the middle of the upper surface of the mounting plate, a turntable fixed to the output shaft of the motor, the turntable being located below the mounting plate, and brackets fixed to both ends of the turntable, with guide wheels movably connected to the brackets for connecting a vibrating guide component.

[0011] Preferably, the vibrating guide includes a guide block disposed on the upper surface of the base plate, the guide block having a guide groove, and a dovetail slider fixed to the bottom end of the guide block, the dovetail slider being located within the dovetail groove.

[0012] Preferably, movable protrusions are fixed to the lower part of both sides of one end of the guide block, and the movable protrusions are connected to the fixed protrusions by a return spring. An L-shaped plate is fixed to one side of one end of the guide block, and the end of the L-shaped plate corresponds to the guide wheel.

[0013] Preferably, the other end of the guide block is connected to a connecting pipe, one end of which is connected to the guide groove, and the other end of which is installed at the discharge port of the rotary table via a mounting plate.

[0014] Beneficial effects

[0015] This utility model provides a multi-stage screening device for spring production and processing. Compared with the prior art, it has the following advantages:

[0016] 1. This multi-stage screening device for spring production and processing uses a drive component to move a vibrating guide component back and forth, causing the guide block to vibrate the connecting pipe. This vibration effectively prevents springs from clogging in the connecting pipe, ensuring that the springs can be smoothly discharged through the connecting pipe and the guide chute. The smooth discharge of the springs ensures the continuous operation of the screening device, greatly improving the efficiency of spring screening and reducing downtime and manual unblocking work caused by blockage.

[0017] 2. The multi-stage screening device for spring production and processing has a drive component guide wheel that can rotate. When it contacts the L-shaped plate of the vibrating guide component, the rotation reduces the friction between the two. This not only reduces the wear of the components and extends the service life of the equipment, but also makes the movement of the guide block smoother, ensuring the stability and continuity of the vibration effect. This better realizes the vibration and guiding function of the spring and improves the performance and reliability of the entire 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] Please see Figure 1-4 The present invention provides the following technical solution:

[0025] A multi-stage screening device for spring production and processing includes a base plate 1, a driving component 2, and a vibrating guide component 3. Both ends of the base plate 1 are provided with movable connecting mechanisms, which are centrally symmetrically distributed. The connecting mechanism on the base plate 1 includes a dovetail groove 11 formed on the upper surface of the base plate 1, and fixed protrusions 12 are provided on both sides of one end of the dovetail groove 11.

[0026] Specifically, the drive component 2 is installed in the middle of the upper surface of the base plate 1. The drive component 2 is used to drive the vibrating guide component 3 to move. The drive component 2 includes a mounting plate 21 fixed in the middle of the upper surface of the base plate 1. A motor 22 is fixed in the middle of the upper surface of the mounting plate 21. A turntable 23 is fixed on the output shaft of the motor 22. The turntable 23 is located below the mounting plate 21. A bracket 24 is fixed at both ends of the turntable 23. A guide wheel 25 is movably connected to the bracket 24 for connecting the vibrating guide component 3. The guide wheel 25 can rotate, which reduces the friction generated when it contacts the vibrating guide component 3.

[0027] More specifically, the vibrating guide 3 is installed on the base plate 1 and connected to the connecting mechanism on the base plate 1. The vibrating guide 3 is connected to the rotating disk 4 of the screening device through the connecting pipe 37. The vibrating guide 3 includes a guide block 31 disposed on the upper surface of the base plate 1. A guide groove 32 is provided on the guide block 31. A dovetail slider 33 is fixed at the bottom end of the guide block 31. The dovetail slider 33 is located in the dovetail groove 11 and plays a guiding and limiting role, so that the guide block 31 maintains linear movement and does not separate from the base plate 1. Movable protrusions 34 are fixed on the lower part of both sides of one end of the guide block 31. 4 is connected to the fixed protrusion 12 by a reset spring 35. The reset spring 35 enables the guide block 31 to automatically reset after movement. One end of the guide block 31 is fixed with an L-shaped plate 36. The end of the L-shaped plate 36 corresponds to the guide wheel 25. When the guide wheel 25 rotates, it can drive the L-shaped plate 36 to move, thereby driving the guide block 31 to move. The guide wheel 25 can rotate when in contact, reducing friction. The other end of the guide block 31 is connected to a connecting pipe 37. One end of the connecting pipe 37 is connected to the guide groove 32. The other end of the connecting pipe 37 is installed at the feed port of the rotary table 4 through the mounting plate 38.

[0028] When this device is in operation, the connecting pipe 37 is first installed at the discharge port of the rotating disc 4 via the mounting plate 38. Then, the screening device is started, and the screening device screens the springs by rotating the disc 4. The screened springs are discharged through the connecting pipe 37 and the guide groove 32 on the guide block 31. The motor 22 is started, and the motor 22 drives the disc 23 to rotate. The disc 23 drives the two guide wheels 25 to make circular motion. The guide wheels 25 contact the L-shaped plate 36 on the guide block 31 and drive the guide block 31 to move on the base plate 1 through the L-shaped plate 36, so that the return spring 35 is compressed. When the guide wheel 25 separates from the L-shaped plate 36, the guide block 31 returns to its original position under the action of the return spring 35. When the other guide wheel 25 contacts the L-shaped plate 36, it drives the guide block 31 to move again. After separation, the guide block 31 returns to its original position. This process is repeated to achieve the vibration effect. The guide block 31 drives the connecting pipe 37 to vibrate, which avoids the spring from getting blocked in the connecting pipe 37 and improves the efficiency of spring screening.
