[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] Please also read Figures 1 to 8, the mixing equipment capable of recording the operation time of the present invention is described. A mixing device capable of recording operation time comprises a mixer 10, a recording unit 20 and a transmission unit 30. The mixer 10 comprises a base 101, a drum 102 rotatably connected to the base 101 and a driving member (not shown) transmission-connected to the drum 102. The drum 102 rotates around its own central axis. A hanging plate 1011 fixedly connected to the base 101 is provided on one side of the drum 102. The hanging plate 1011 is perpendicular to the rotation axis of the drum 102. The recording unit 20 comprises a measuring paper (not shown) and two rollers 201 rotationally connected to the hanging plate 1011. The rotation axes of the two rollers 201 are parallel to the horizontal direction. The measuring paper is wound around one of the rollers 201, and the free end of the measuring paper is connected to the other roller 201. The transmission unit 30 comprises a reciprocating portion slidably connected to the hanging plate 1011, and the reciprocating portion is transmission-connected to the roller 201. When the drum 102 rotates one circle, the reciprocating portion slides back and forth once.

[0020] Compared with the prior art, the mixing equipment provided in this embodiment that can record the operation time is that the driving member drives the rotating drum 102 to rotate so that the two materials in the rotating drum 102 are evenly mixed. During the rotation of the rotating drum 102, the two rollers 201 are rotated synchronously through the transmission unit 30, so that the rolled measuring paper is transferred from one roller 201 to another roller 201; before the mixing starts, the measuring paper of appropriate specifications is selected. When the measuring paper is completely transferred from one roller 201 to another roller 201, it means that the mixing process has been running for a sufficient time. If there is a sudden power outage in the middle of the mixing process, the transfer of the measuring paper will also stop. After the power is restored, the mixing process will continue to run and the transfer of the measuring paper will continue. It is only necessary to observe whether the measuring paper has been completely transferred to know whether the running time of the mixing process meets the requirements, without recalculating the running time of the mixing process, thereby improving the mixing efficiency.

[0021] In some embodiments, see Figures 1 to 3 An extrusion block 1021 is fixedly provided on the outer wall of the rotating drum 102, and the transmission unit 30 also includes a reciprocating rod 301 and an elastic member 302. The reciprocating rod 301 forms a reciprocating portion, and the reciprocating rod 301 slides in a direction away from the rotating drum 102 after being squeezed by the extrusion block 1021; the elastic member 302 is fixedly provided between the reciprocating rod 301 and the hanging plate 1011, and is configured with a pre-tightening force that causes the reciprocating rod 301 to slide toward the side close to the rotating drum 102.

[0022] Specifically, the transmission unit 30 also includes a transmission assembly corresponding to the roller 201 one by one, and the transmission assembly includes a first transmission shaft 303, a first transmission rod 304 and a rebound member 305. The first transmission shaft 303 is connected to the hanging plate 1011 for rotation around the vertical direction. The first transmission shaft 303 is connected to the roller 201 for transmission. The first transmission shaft 303 has a first hollow cavity 3031, and the inner wall of the first hollow cavity 3031 is spirally provided with a first turning groove 3032. The inner wall of the first hollow cavity 3031 is provided with a first rebound groove 3033 along the vertical direction. The bottom end of the first rebound groove 3033 is connected to the first turning groove 3031. 032 is connected to the tail end; the first transmission rod 304 passes through the first hollow cavity 3031, and the outer wall of the first transmission rod 304 is fixedly provided with a first steering block 3041 which is slidably adapted to the first steering groove 3032 and the first rebound groove 3033, and the outer wall of the first transmission rod 304 is fixedly provided with a reset plate 3042. The first transmission rod 304 moves downward after being squeezed by the reciprocating rod 301, and the first transmission rod 304 is squeezed by the reciprocating rod 301 at the same time; the rebound member 305 is fixedly arranged between the hanging plate 1011 and the reset plate 3042, and is configured with a pre-tightening force that causes the first transmission rod 304 to move upward.

[0023] It should be noted that the first transmission shaft 303 is connected to the rotating roller 201 through a bevel gear set, and a protrusion 3011 for pressing the first transmission rod 304 is provided on the bottom wall of the reciprocating rod 301 .

[0024] During the rotation of the drum 102, the extrusion block 1021 contacts the reciprocating rod 301 once for each rotation of the drum 102; after the extrusion block 1021 contacts the reciprocating rod 301, the extrusion block 1021 squeezes the reciprocating rod 301, causing the reciprocating rod 301 to move away from the drum 102; during the movement of the reciprocating rod 301 away from the drum 102, the first transmission rod 304 is squeezed, causing the first transmission rod 304 to move downward; during the downward movement of the first transmission rod 304, the first steering block 3041 slides in the first steering groove 3032, thereby causing the first transmission shaft 303 to rotate; the first transmission shaft 303 causes the roller 201 to rotate through the bevel gear set, thereby completing a transfer of the metered paper.

[0025] After the metering paper completes one transfer, the rebound member 305 and the elastic member 302 release their elastic forces at the same time. The rebound member 305 releases its elastic force to cause the first transmission rod 304 to move upward. During the upward movement of the first transmission rod 304, the first steering block 3041 slides in the first rebound groove 3033, thereby the first transmission rod 304 is reset. The elastic member 302 releases its elastic force to cause the reciprocating rod 301 to move toward the direction close to the rotating drum 102 until the reciprocating rod 301 is reset.

[0026] In some embodiments, see Figure 4 and Figure 5The transmission unit 30 also includes a telescopic member 306 forming a reciprocating portion, and the telescopic member 306 is telescopic in length along the up and down directions; wherein, the telescopic member 306 completes an extension and retraction action every time the drum 102 rotates one circle.

The top end of the second transmission rod 308 is fixedly connected to the bottom end of the telescopic member 306.

[0028] It should be noted that the second transmission shaft 307 is connected to the rotating roller 201 through a bevel gear set, and the telescopic member 306 can be an electric cylinder, a telescopic oil cylinder, or a hydraulic cylinder.

[0029] During the rotation of the drum 102, the telescopic member 306 completes an extension and retraction action every time the drum 102 rotates one circle; the telescopic member 306 extends downward to drive the second transmission rod 308 to move downward, and the second steering block 3081 slides in the second steering groove 3072 during the downward movement of the second transmission rod 308, thereby causing the second transmission shaft 307 to rotate, and the second transmission shaft 307 causes the roller 201 to rotate through the bevel gear set, thereby completing a transfer of the metering paper; the telescopic member 306 is retracted upward to drive the second transmission rod 308 to move upward, and the second steering block 3081 slides in the second rebound groove 3073 during the upward movement of the second transmission rod 308, thereby completing the reset of the second transmission rod 308.

[0030] In some embodiments, see Figure 4 The telescopic member 306 and the second transmission rod 308 are arranged in a one-to-one correspondence, and the bottom end of the telescopic member 306 is fixedly connected to the top end of the corresponding second transmission rod 308.

[0031] Two telescopic members 306 are provided, and the two telescopic members 306 correspond to one second transmission rod 308 respectively, so that the telescopic member 306 is more stable when driving the second transmission rod 308 .

[0033] The two second transmission rods 306 are driven to move simultaneously by one telescopic member 306 , thereby reducing the cost.

[0034] In some embodiments, the transmission unit 30 also includes an angle sensor that is communicatively connected to the telescopic member 306, and the angle sensor is used to monitor the angle of rotation of the rotating drum 102; whenever the angle sensor detects that the rotating drum 102 has rotated 360 degrees, the telescopic member 306 performs an extension and retraction action.

[0035] In some embodiments, see Figure 7 A fastening groove 2011 is provided on the outer wall of the roller 201; the recording unit 20 also includes two mounting cylinders 202, which are respectively sleeved on the roller 201, and the mounting cylinders 202 are detachably connected to the roller 201.

[0037] It should be noted that the adsorption portion 40 can be a vacuum suction cup. When the vacuum suction cup is powered on, suction is generated to fix the end of the measuring paper in the fastening groove 2011. When the vacuum suction cup is powered off, the suction disappears and the end of the measuring paper can be taken out of the fastening groove 2011.

[0038] Before mixing, select appropriate measuring paper according to the mixing time, pass the end of the measuring paper through the through slot 2021 and extend it into the fastening slot 2011, and then energize the vacuum suction cup so that the end of the measuring paper is fixed in the fastening slot 2021; when the measuring paper needs to be removed, the vacuum suction cup is powered off and the measuring paper is separated from the fastening slot 2021.

[0039] In some embodiments, see Figure 8 A pressing plate 50 is provided in the fastening groove 2011, and the pressing plate 50 is rotatably connected to the inner wall of the fastening groove 2011.
