Speed ​​control device for continuous steel plate production

Abstract

This utility model relates to a speed control device for continuous steel plate production, including an upper and lower adjusting column, an adjusting rod, a contact rod, a sensing component, and a main control component. One end of the adjusting rod is provided with a connecting arm, which is inclined and hinged to the upper side wall of the upper and lower adjusting column. The contact rod is provided with a sliding groove, and the adjusting rod is locked in the sliding groove and slidably connected. The sensing component is used to sense the swing angle of the connecting arm. When the swing angle exceeds a set value, the sensing component sends a signal to the main control component to control the feeder to stop. By adjusting the height of the upper and lower adjusting column, the contact rod is positioned above the steel plate conveying area. When too many steel plates accumulate in the conveying area, the steel plates will bulge and press against the contact rod, causing the contact rod to move upward and deflect the connecting arm. When the swing angle of the connecting arm reaches the set value, it will be sensed by the sensing component, which will send a signal to control the feeder to automatically stop.

Description

Technical Field

[0001] This utility model belongs to the technical field of steel plate production equipment, specifically relating to a speed control device for continuous steel plate production. Background Technology

[0002] Currently, in the steel plate joining process, a relatively long space needs to be left between the feeding mechanism and the pressing mechanism. This is because during the production process, the feeding speed of the feeding mechanism is greater than the pressing speed of the pressing mechanism, and due to inertia, a space needs to be left between the two to allow the steel plates to transition. However, with this method, after a certain period of time, as the steel plates accumulate, it is necessary to manually stop the feeding mechanism, let the pressing mechanism work for a period of time, and then restart the feeding mechanism. To solve this problem, this solution was developed. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a speed control device for continuous steel plate production, which can automatically stop the feeder when too much steel plate is piled up.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a speed control device for continuous steel plate production, including an upper and lower adjusting column, an adjusting rod, a contact rod, a sensing component, and a main control component. One end of the adjusting rod is provided with a connecting arm, which is inclined and hinged to the upper side wall of the upper and lower adjusting column. The contact rod is provided with a sliding groove, and the adjusting rod is locked in the sliding groove and slidably connected. The sensing component is used to sense the swing angle of the connecting arm. When the swing angle is greater than a set value, the sensing component sends a signal to the main control component to control the feeder to stop.

[0005] Furthermore, one end of the slide groove has a constricted opening, and the end of the adjusting rod is provided with a locking platform. The diameter of the locking platform is the same as that of the slide hole, and the locking platform slides within the slide hole.

[0006] Furthermore, the sensing component includes an infrared receiver, an infrared transmitter, a detection plate, and a synchronization rod. The up-and-down adjusting column has a rotating hole. One end of the synchronization rod passes through the rotating hole and is connected to the connecting arm, while the other end is connected to the detection plate. The infrared receiver or infrared transmitter is disposed on the side wall of the up-and-down adjusting column, facing outwards and towards the infrared receiver or infrared transmitter. The detection plate is located between the infrared receiver and the infrared transmitter, and is tilted downwards towards the side away from the connecting arm. The tilt angle of the detection plate is a set value for the swing angle.

[0007] Furthermore, the side wall of the vertically adjustable column is formed with an L-shaped connecting plate, and the infrared transmitter or infrared receiver is disposed in the vertical part of the L-shaped connecting plate.

[0008] Furthermore, the upper and lower adjustable column includes a lower fixed tube and an upper adjustable tube. The side wall of the lower fixed tube forms a plurality of locking holes spaced vertically apart. The lower end side wall of the upper adjustable tube forms an installation groove. A locking ball is provided at the opening of the installation groove. An elastic body is provided between the locking ball and the installation groove.

[0009] Furthermore, a stable base is provided at the bottom of the lower fixing tube.

[0010] Furthermore, a torsion spring is provided between the synchronizing rod and the rotating hole.

[0011] Furthermore, there are two vertical adjustment columns and two adjustment rods. The two vertical adjustment columns are arranged opposite each other at intervals. The two adjustment rods are respectively hinged to the two vertical adjustment columns through connecting arms. The bottom surface of the slide groove extends through to the end face of the contact rod. The two adjustment rods extend into the slide groove from both ends of the contact rod and are slidably connected.

[0012] Furthermore, the sensing component includes a toggle switch, which is disposed above the connecting arm.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, the height of the vertical column is adjusted so that the contact rod is positioned above the steel plate conveying area. When too many steel plates accumulate in the conveying area, the steel plates will bulge and press against the contact rod. The contact rod moves upward, causing the connecting arm to deflect. When the swing angle of the connecting arm reaches the set value, it will be sensed by the sensing component and a signal will be sent to control the feeder to stop automatically. The stopping time can be set according to the pressing speed of the pressing plate mechanism. This method avoids the need for manual supervision of the feeder. Attached Figure Description
