Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

A rolling apparatus having a flange bar protecting function according to an embodiment of the present utility model will be described below with reference to fig. 1 to 5, and some embodiments of the present application will be described in detail below with reference to the accompanying drawings, in which the following embodiments and features of the embodiments may be combined with each other without conflict.

The roller press has the advantages of high yield, low energy consumption and stable production, and is widely applied to ceramic green bricks, cement and mine industries. When the existing roller press is used for producing green bricks, powder is conveyed to a compaction area of the roller press through a conveying belt, and pressure is applied to the powder under the combined action of an upper pressing roller driven by an oil cylinder and a lower pressing roller fixedly installed in the compaction area, so that the rolling and forming of the ceramic green bricks are realized. Moreover, in the existing rolling equipment, a flange strip 11 is also arranged on a conveying belt, and the flange strip 11 is used for restraining lateral flow of powder, so that the powder is prevented from diffusing to two sides when being pressed, and the edge of a green brick is ensured to be molded.

However, when the roller press is running, the bottom surface of the flange 11 is subject to force along the movement direction of the conveyor belt, i.e. force in the direction C in fig. 3, and when the force applied to the flange 11 is too large, the flange 11 is easily separated or wound into the compaction area of the roller press, which is easy to cause damage to the roller press, and there is an improvement.

In view of this, the rolling apparatus according to the embodiment of the present utility model includes the lower conveyor belt 31, the flange 11 and the flange protection mechanism 1 by providing the pressure sensor 14, referring to fig. 1 to 5. Wherein the lower conveyor belt 31 is for conveying the powder.

Specifically, the flange 11 is used for restraining the powder, and lateral restraint can be provided for the powder in the lateral direction of the lower conveying belt 31, so that the rolling device can be used for pressing powder products with required sizes.

Specifically, the edge guard mechanism 1 includes a frame, a first fixing plate 12, a second fixing plate 13, and a pressure sensor 14. The first fixing plate 12 is arranged at one end of the flange 11, the second fixing plate 13 is connected to the frame, and the second fixing plate 13 is limited to move along the conveying direction of the lower conveying belt 31 because the frame is stationary, and the second fixing plate 13 is stationary; the pressure sensor 14 is abutted between the first fixed plate 12 and the second fixed plate 13; and the pressure sensor 14 is preset with a pressure threshold value, and when the pressure value received by the pressure sensor 14 is larger than the pressure threshold value, the rolling equipment stops running. And preferably, the first fixing plate 12, the pressure sensor 14, and the second fixing plate 13 are disposed in order along the conveying direction of the lower conveying belt 31. Wherein being restricted to move in the conveying direction of the lower conveying belt 31 means that the workpiece does not move with the conveying of the lower conveying belt 31, for example, the workpiece cannot move in the conveying direction of the lower conveying belt 31, or the workpiece is stationary.

In practical application, the rolling device presets a pressure threshold F in the pressure sensor 14 by setting the pressure sensor 14, the preset pressure threshold F is slightly smaller than the maximum value of the pressure value which can ensure that the flange 11 works normally, when the force applied to the flange 11 is larger than the preset pressure threshold F of the pressure sensor 14, the pressure sensor 14 can send a stop signal to the rolling device, so that the rolling device stops working, the powder conveying is interrupted, the flange 11 is prevented from being separated or wound into a compaction area of the rolling machine, and damage to the rolling device is prevented.

It should be noted that the preset pressure value can be obtained through multiple experiments, and the maximum value of the pressure value received by the flange 11 during normal operation can be ensured through multiple experiment records, and of course, the preset pressure threshold F should be slightly smaller than the maximum value of the pressure value received by the flange 11 during normal operation.

Further, for enhanced protection, the rolling device of the embodiment of the present utility model is provided with a proximity switch 16 in addition to the pressure sensor 14, and referring to fig. 1 to 5, the edge guard mechanism 1 includes a connecting member 15 and the proximity switch 16.

Specifically, the connecting piece 15 is disposed at one end of the flange 11; the proximity switch 16 is used for detecting the position of the connecting piece 15; and, when the proximity switch 16 and the connecting member 15 are staggered, the rolling apparatus stops operating.

In practical application, this roll-in equipment is through setting up proximity switch 16, and under the normal operating condition of flange strip 11, proximity switch 16 can specifically set up directly over flange strip 11, and proximity switch 16 and connecting piece 15 both are along vertical coincidence setting, and this roll-in equipment normal operating now. Once the flange 11 is separated, the sensing surfaces of the connecting piece 15 and the proximity switch 16 are staggered, wherein the staggering means that the connecting piece 15 is not in the sensing range of the sensing surface of the proximity switch 16, the connecting piece 15 is separated from the sensing range of the proximity switch 16, and the proximity switch 16 sends a stop signal to the rolling equipment at the moment so as to stop the rolling equipment, interrupt the powder conveying, prevent the flange 11 from being separated or wound into the compaction area of the rolling machine, and prevent the rolling equipment from being damaged. In summary, by the double detection of the pressure sensor 14 and the proximity switch 16, the rolling equipment is protected from damage.

It should be noted that the proximity switch 16 may be specifically an inductive proximity switch 16, where the connection member 15 is configured as a conductive member, and when the connection member 15 moves near the proximity switch 16 that generates an electromagnetic field, an eddy current is generated inside the conductive object due to electromagnetic induction, and the eddy current reacts to the proximity switch 16 to change parameters inside the switch, so as to sense whether the conductive object moves near, and further control on/off of the switch. Alternatively, the proximity switch 16 may be specifically a capacitive proximity switch 16, and when the connecting member 15 moves toward the proximity switch 16, the dielectric constant of the capacitor is always changed due to the proximity of the connecting member 15, so that the capacitance is changed, and the state of a circuit connected to the measuring head is changed, so that the switch can be controlled to be turned on or off. Alternatively, the proximity switch 16 may be embodied as a photoelectric switch, and when the connector 15 is in proximity, the photoelectric device receives reflected light and outputs a signal, so that whether an object is in proximity can be "perceived" as being in proximity.

lower drive motors

24 and 34, respectively, for controlling the upper and

lower drive motors

24 and 34.

In practical applications, the upper driving motor 24 drives the upper compacting belt 21 to rotate by driving the upper roller set, and the lower driving motor 34 drives the lower conveying belt 31 by driving the lower roller set, so that the upper driving motor 24 and the lower driving motor 34 need to be stopped when the rolling apparatus is stopped.

The rolling equipment is characterized in that a pressure threshold F is preset in the pressure sensor 14 by arranging the pressure sensor 14, the preset pressure threshold F is slightly smaller than the maximum value of the pressure value which can ensure that the flange 11 works normally, when the force applied to the flange 11 is larger than the preset pressure threshold F of the pressure sensor 14, the pressure sensor 14 sends a stop signal to the PLC 4, and the PLC 4 sends a stop signal to the upper transmission motor 24 and the lower transmission motor 34, so that the upper transmission motor 24 and the lower transmission motor 34 stop working, the rolling equipment stops working, the powder conveying is interrupted, the flange 11 is prevented from being separated or wound into a compacting zone of the rolling equipment, and damage to the rolling equipment is prevented.

Or, this roll-in equipment is through setting up proximity switch 16, when flange strip 11 is disengaged, can make the sensing surface of connecting piece 15 and proximity switch 16 stagger mutually, at this moment proximity switch 16 can send a stop signal to PLC controller 4, PLC controller 4 sends stop signal to last driving motor 24 and lower driving motor 34 to make last driving motor 24 and lower driving motor 34 stop working, and then make this roll-in equipment stop working, interrupt the transport of powder, prevent flange strip 11 to disengage or roll into the roll-in machine compaction district, prevent the damage of cost roll-in equipment of making.

Of course, the PLC controller 4 may be further specifically connected to an alarm, when the force applied to the flange 11 is greater than the preset pressure threshold F of the pressure sensor 14, the pressure sensor 14 will send a stop signal to the PLC controller 4 at this moment, and the PLC controller 4 will send an alarm signal to the alarm, and the alarm will alarm to alert the staff, in addition to sending a stop signal to the upper driving motor 24 and the lower driving motor 34.

Or when the flange 11 is disconnected, the sensing surfaces of the connecting piece 15 and the proximity switch 16 are staggered, at the moment, the proximity switch 16 sends a stop signal to the PLC controller 4, and the PLC controller 4 sends an alarm signal to an alarm in addition to the stop signal to the upper transmission motor 24 and the lower transmission motor 34, and the alarm sounds to alarm to remind workers.
