Description

Technical Field

[0001] This utility model relates to the technical field of material sample preparation equipment, and in particular to an automated sample bottle capping machine. Background Technology

[0002] In the sampling, sample preparation, and testing of materials (such as ores and coal), it is necessary to transfer the prepared samples from one workstation (laboratory) to the next workstation (laboratory) for the next stage of work. Currently, the sample transfer process requires the use of sample bottles and a sample bottle capping machine. The prepared samples are first bottled, and then the caps are tightened using the sample bottle capping machine before being transported.

[0003] Sample bottles and caps used in different fields vary in size and height. Commonly used capping machines can only tighten sample bottles of fixed height and caps of the same size. Before capping sample bottles of other sizes, manual adjustments are required, which affects work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automated sample bottle capping machine that can automatically cap sample bottles of different models without requiring manual adjustments after changing sample bottles, thereby improving work efficiency.

[0005] To achieve the above objectives, an automated sample bottle capping machine is provided, comprising a support frame and a sample bottle body. A first electric push rod is fixedly connected to one end of the support frame, and the piston rod of the first electric push rod passes through the support frame and slides along it. A fixing mechanism is fixedly connected to the piston rod of the first electric push rod, and the fixing mechanism fixes the sample bottle body. A second electric push rod is fixedly connected to the top of the support frame, and a mounting plate is fixedly connected to the upper end of the piston rod of the second electric push rod. Sliding rods are respectively provided on both sides of the second electric push rod, and the top ends of the sliding rods are fixedly connected to the mounting plate. The lower ends of the sliding rods pass through the support frame and slide along it. A capping mechanism is fixedly connected to the lower end of the mounting plate, and the sample bottle body is located below the center of the capping mechanism. An electrical cabinet is fixedly connected to the side of the support frame away from the guide block. This machine can automatically cap sample bottles of different models without requiring manual adjustment after sample bottle replacement, thus improving work efficiency.

[0006] According to the aforementioned automated sample bottle capping machine, the fixing mechanism comprises a first slider, an adjusting motor, a first mounting frame, a first clamping block, a first pressure sensor, and a first lead screw. The first mounting frame has a U-shaped structure and is fixedly connected to the piston rod of a first electric push rod. A sliding groove is formed on the side of the first mounting frame away from the first electric push rod. The first lead screw is located in the middle of the sliding groove, and both ends of the first lead screw are rotatably connected to the first mounting frame. Two first sliders are provided and symmetrically arranged in the sliding groove, and the first lead screw passes through the middle of each first slider. The first lead screw drives the first slider to move linearly in the sliding groove. The adjusting motor is fixedly connected to one end of the first mounting frame, and the output end of the adjusting motor is fixedly connected to the first lead screw through a coupling. The first clamping block is located inside the first mounting frame and is fixedly connected to the first slider. The first clamping blocks on the two first sliders clamp the sample bottle body. The first pressure sensor is installed on the surface of the first clamping block and detects the force applied by the first clamping block to the sample bottle body. The motor controls the rotation of the first lead screw, which causes the first slider to drive the first clamping block to clamp the sample bottle body. The first pressure sensor detects whether the first clamping block is in contact with the sample bottle body and applies pressure, thereby clamping sample bottles of different models.

[0007] According to the automated sample bottle capping machine, a positioning detection sensor is installed at the upper end of the first mounting bracket of the fixing mechanism, and the positioning detection sensor detects the sample bottle body. The positioning detection sensor is used to detect whether the sample bottle has reached below the capping mechanism, thereby causing the first electric push rod to push the fixing mechanism, so that the sample bottle body is positioned in the fixing mechanism.

[0008] According to the aforementioned automated sample bottle capping machine, the capping mechanism comprises a third electric push rod, a second mounting frame, a drive mechanism, a guide rail, a rotating block, and a second pressure sensor. The second pressure sensor is mounted on the lower end of the mounting plate, and the second mounting frame is fixedly connected to the lower end of the second pressure sensor. A chamber is formed in the middle of the lower end of the second mounting frame. The guide rail is fixedly connected to the top of the chamber, and four guide rails are provided and equidistantly distributed around the circumference of the chamber. The drive mechanism is located in the chamber, and its top end is slidably connected to the inner wall of the guide rail. The third electric push rod is fixedly connected to the outer end of the second mounting frame, and its piston rod passes through the second mounting frame and is slidably connected to it. The piston rod of the third electric push rod is fixedly connected to the drive mechanism. The drive mechanism cooperates to cap the sample bottle body. The rotating block is located in the middle of the top of the chamber and is embedded in the second mounting frame and rotatably connected to it. The capping mechanism is controlled to descend by the second electric push rod, so that the top of the sample bottle body enters the capping mechanism and applies downward pressure to the cap on the top of the sample bottle body to prevent the cap from falling off during capping. The third electric push rod pushes the drive mechanism to approach the cap on the top of the sample bottle body, and drives the cap to rotate while clamping the cap, so as to tighten it on the sample bottle body. The second pressure sensor detects the pressure of the second mounting bracket in contact with the cap, and the rotating block avoids friction from affecting the rotation of the cap.

[0009] According to the automated sample bottle capping machine, a rubber block is fixedly connected to the lower end of the rotating block. The rubber block is used to increase friction and prevent relative rotation between the bottle cap and the rotating block.

[0010] According to the aforementioned automated sample bottle capping machine, the driving mechanism comprises a second clamping block, a driving roller, a capping motor, and a second slider. The second slider is disposed in a guide rail and slidably connected to the inner wall of the guide rail. The second clamping block is fixedly connected to the lower end of the second slider. The piston rod of the third electric push rod is fixedly connected to the end of the second clamping block away from the rotating block. The driving roller is disposed inside the second clamping block, and its upper and lower ends are rotatably connected to the inner wall of the second clamping block. The driving roller passes through the end of the second clamping block facing the rotating block, and its surface is provided with anti-slip patterns. The capping motor is fixedly connected to the lower end of the second clamping block, and its output end is fixedly connected to the rotating shaft in the middle of the driving roller via a coupling. The capping motor controls the rotation of the driving roller, thereby causing the bottle cap to rotate when the driving roller contacts the bottle cap. The cooperation between the second slider and the guide rail is used to improve the stability of the second clamping block during movement.

[0011] According to the aforementioned automated sample bottle capping machine, a torque sensor is installed inside the capping motor. This sensor is used to detect changes in the torque and rotational speed of the capping motor, thereby detecting whether the bottle cap is tightened.

[0012] The above solution has the following advantages: the third electric push rod pushes the drive mechanism to approach the bottle cap on the top of the sample bottle body, and drives the bottle cap to rotate while clamping the bottle cap, thereby tightening it on the sample bottle body. The second pressure sensor detects the pressure of the second mounting bracket in contact with the bottle cap. The rotating block avoids friction from affecting the rotation of the bottle cap, so that the device can tighten bottle caps of different sizes.
