For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0035] Specific structure such as Figure 1-4 shown.

[0036] The oil press provided in this embodiment includes: a casing, a pressing screw shaft 200, a driving motor 300, a pressure detection element 500, a display screen and a controller.

[0037] The casing has a pressing chamber 110, a feed port 120, a discharge port 130 and an oil outlet 140. The feed port 120, the discharge port 130 and the oil outlet 140 are all connected to the pressing chamber 110. The pressing screw shaft 200 is penetrated by the pressing chamber 110, and the driving motor 300 is transmission-connected to the pressing screw shaft 200.

[0038] The pressure detection element 500 is embedded in the inner wall of the pressing chamber 110 , and the pressure detection element 500 and the display screen are both electrically connected to the controller.

[0039] With the above structure, the material is fed into the pressing chamber 110 of the casing from the feed port 120, the drive motor 300 is started, and the drive motor 300 drives the pressing screw shaft 200 to rotate. The pressing screw shaft 200 rotates to squeeze the material and drives the material to move toward the discharge port 130. In the process of gradually squeezing the material, the material is squeezed to produce oil, and the oil flows out from the oil outlet 140. The squeezed material is discharged from the discharge port 130. In the above squeezing process, the material is squeezed by the squeezing screw shaft 200, and the internal pressure of the material increases, so that the pressure of the material on the wall of the squeezing chamber 110 increases. The pressure detection element 500 is embedded in the wall of the squeezing chamber 110. The pressure detection element 500 detects the pressure applied by the material on the wall and transmits the pressure signal to the controller. The controller processes the pressure signal and transmits it to the display screen. The display screen can display the pressure value to the staff.

[0040] In the above structure, the pressing screw shaft 200 rotates to squeeze the material and provide pressing pressure for the material. The pressure exerted on the material is transmitted to the cavity wall of the pressing cavity 110. The pressure detection element 500 embedded in the cavity wall can detect the pressure signal and transmit the pressure signal to the controller. The controller processes the pressure signal and transmits it to the display screen. The display screen can display the pressure value to the staff, so that the staff can intuitively read the pressure value and obtain the material pressure in the pressing cavity 110, avoiding the technical problem in the prior art that it is impossible to judge the pressure applied to the material inside the oil press, resulting in an inability to judge whether the material is sufficiently pressed.

[0041] In the optional technical solution of this embodiment, the casing includes a pressing shell 100, a pressing chamber 110 is arranged in the pressing shell 100, a cavity wall of the pressing chamber 110 is provided with a receiving groove 160, a notch of the receiving groove 160 is connected to the pressing chamber 110, and a pressure detection element 500 is arranged in the receiving groove 160.

[0042] Specifically, the pressing shell 100 has a pressing chamber 110, and the pressing screw shaft 200 is inserted into the pressing chamber 110. The material enters the pressing chamber 110 from the feed port 120. The driving motor 300 drives the pressing screw shaft 200 to start and press the material. During the pressing process of the material, the material is under pressure. The receiving tank 160 is connected to the pressing chamber 110. The material transmits the pressure to the pressure detection element 500 in the receiving tank 160. The pressure detection element 500 detects the pressure of the material and transmits the pressure signal to the controller. The controller analyzes and processes the pressure signal and displays it through the display screen.

[0043] In an optional technical solution of this embodiment, the oil press further includes a pressure guide plate 600 , which is disposed in the accommodating groove 160 , one side of the pressure guide plate 600 abuts against the pressure detection element 500 , and the other side of the pressure guide plate 600 is disposed toward the notch of the accommodating groove 160 .

[0044] Specifically, the pressure guiding plate 600 is arranged in the receiving groove 160, and the material transfers the pressure to the pressure guiding plate 600, and the pressure guiding plate 600 transfers the pressure to the pressure detecting element 500. The force-bearing surface of the pressure guiding plate 600 is relatively large. The material transfers the pressure to the pressure guiding plate 600, and the pressure exerted on the pressure guiding plate 600 is relatively uniform. Therefore, the setting of the pressure guiding plate 600 can uniformly transfer the pressure of the material in the pressing chamber 110, so that the pressure detected by the pressure detecting element 500 is more uniform and accurate, thereby avoiding large errors in pressure detection due to uneven force.

[0045] In an optional technical solution of this embodiment, a blocking portion 170 is provided at the notch of the accommodating groove 160 , and the blocking portion 170 abuts against the pressure guiding sheet 600 .

[0046] Specifically, when the press is operating normally, the material has a certain pressure in the press chamber 110, and the material applies pressure to the pressure guide sheet 600, so that the pressure guide sheet 600 can be tightly pressed on the pressure detection element 500. When the material in the press chamber 110 is discharged from the press chamber 110, the pressure in the press chamber 110 is lost, and the pressure guide sheet 600 loses pressure extrusion. At this time, the blocking part 170 can press against the pressure guide sheet 600 to prevent the pressure guide sheet 600 from falling out of the receiving groove 160.

[0047] In an optional technical solution of this embodiment, the housing has an inspection port and a cover plate 150 , the inspection port is connected to the receiving groove 160 , and the cover plate 150 can cover the inspection port.

[0048] Specifically, the inspection port is connected to the receiving tank 160. When the pressure detection element 500 needs to be inspected and maintained, the inspection port is opened, and the operator can directly inspect and maintain the pressure detection element 500 in the receiving tank 160 through the inspection port. When the oil press is working normally, the cover plate 150 normally covers the inspection port to prevent material from leaking from the inspection port.

[0049] In the optional technical solution of this embodiment, the number of pressure detection elements 500 is multiple, the number of accommodating grooves 160 opened on the cavity wall of the pressing cavity 110 is consistent with the number of pressure detection elements 500, and the pressure detection elements 500 and the accommodating grooves 160 are arranged in a one-to-one correspondence, and along the extension direction of the pressing screw shaft 200, multiple accommodating grooves 160 are arranged at intervals.

[0050] Specifically, the wall of the squeezing chamber 110 is provided with a plurality of receiving grooves 160, each receiving groove 160 is provided with a pressure detection element 500, and a pressure guide sheet 600 is provided at the front end of each pressure detection element 500, and a blocking portion 170 for preventing the pressure guide sheet 600 from falling off is provided at the notch of each receiving groove 160. The plurality of pressure detection elements 500 are arranged along the extension direction of the squeezing screw shaft 200, so that the pressure detection elements 500 can detect the pressure values ​​at different positions in the axial direction of the squeezing chamber 110, and the controller displays the pressure values ​​at different positions to the staff through the display screen, and the staff can make judgments on the material squeezing conditions according to the pressure values ​​at different positions.

[0051] In an optional technical solution of this embodiment, the housing further includes a heating layer 400 , which is sleeved on the outside of the pressing shell 100 , and the heating layer 400 is in contact with the pressing shell 100 .

[0052] Specifically, the heating layer 400 includes a heating wire 410 and an outer heat-insulating shell 420. The heating wire 410 is wound around the outside of the pressing shell 100, and the outer heat-insulating shell 420 is disposed outside the heating wire 410. The heating wire 410 can be powered on and heated to heat the pressing shell 100, so that the temperature of the material in the pressing chamber 110 is increased, thereby improving the oil extraction rate. The outer heat-insulating shell 420 is disposed outside the heating wire 410 to prevent the operator from touching the heating wire 410 and getting burned. At the same time, the outer heat-insulating shell 420 can also play a role in heat insulation.

[0053] In an optional technical solution of this embodiment, the oil press also includes an alarm component, and the alarm component is electrically connected to the controller.

[0054] Specifically, during the normal operation of the oil press, the pressure detection element 500 detects the pressure at different positions in the pressing chamber 110, and the controller compares the pressure data with the preset value. When the preset value exceeds or is less than the preset value range, the controller controls the alarm component to sound an alarm, thereby reminding the staff to pay attention to checking the pressure data.

[0055] In an optional technical solution of this embodiment, the alarm component includes a light alarm element and a sound alarm element, and the light alarm element and the sound alarm element are both electrically connected to the controller.

[0056] Specifically, during the normal operation of the oil press, the pressure detection element 500 detects the pressure at different positions in the pressing chamber 110, and the pressure data is transmitted to the controller. The controller compares the pressure data with the preset value. When the pressure data is greater than the preset value range or less than the preset value range, the controller controls the light alarm element and the sound alarm element to alarm at the same time to remind the staff to pay attention to check the pressure data.

[0057] This embodiment also provides a pressing device.

[0058] Since the pressing equipment is implemented by an oil press, the advantages of the pressing equipment, including the advantages of the above-mentioned oil press, will not be repeated.
