Description

Technical Field

[0001] This utility model relates to the field of bagged product testing technology, specifically a continuous bag pressure testing instrument. Background Technology

[0002] Currently, not all sealed bagged products on the market (liquid or small-particle cosmetics, chemicals, food, pharmaceuticals, etc.) have undergone packaging design pressure testing. They are all tested by manual sampling. After leaving the factory, they are prone to leakage and pressure loss, which may affect the product's shelf life or quality. Summary of the Invention

[0003] To address the aforementioned problems, the purpose of this invention is to provide a continuous bag pressure testing instrument.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: a continuous bag pressure detector, comprising a transmission device and a pressure plate disposed above the transmission structure of the transmission device, wherein a pressure sensor is disposed on the upper surface of the pressure plate, and the measuring end of the pressure sensor is fixedly connected to the lower telescopic end of a pressure measuring cylinder fixed above the transmission device.

[0005] Furthermore, the top of the frame of the transmission device is fixed with multiple vertical support rods. Each support rod has vertically arranged scale lines at its upper end. The four corners of the cylinder fixing plate are respectively fitted onto the support rods at the corresponding scale lines. The four corners of the cylinder fixing plate are respectively provided with locking bolts for clamping and fixing the support rods. The pressure measuring cylinder passes vertically through the cylinder fixing plate and is fixedly connected to the cylinder fixing plate.

[0006] Furthermore, an L-shaped fixing plate is provided on one side of the frame of the transmission device. A horizontal elongated fixing groove of the fixing plate is used to fix an adjustable position sensor. The sensing end of the position sensor corresponds to the surface of the transmission structure of the transmission device directly below the pressure plate.

[0007] Furthermore, the conveying device is a conveyor belt driven by a motor, and the conveyor belt is fixedly supported on the top of the conveying device frame.

[0008] Furthermore, a power distribution box is fixed inside the transmission device frame.

[0009] Furthermore, a control panel for controlling the operation of the pressure measuring cylinder is provided on one side of the top of the transmission device frame.

[0010] Furthermore, the bottom of the transmission device frame is fixed with multiple arc-shaped bottom supports.

[0011] Furthermore, vertical guide rods are respectively passed through the cylinder fixing plates on both sides of the pressure measuring cylinder, and the lower ends of the guide rods on each side are fixedly connected to the upper surface of the pressure plate.

[0012] With the above settings, this utility model has the following advantages:

[0013] This invention is not only simple in structure and low in cost, but also easy to automate. It can effectively replace manual sampling inspection, avoid missed inspections or failure to pick up, and ensure the pass rate of bagged packaged products leaving the factory. While saving labor costs, it can also reduce defective products caused by unqualified packaging.

[0014] The four corners of the cylinder fixing plate are respectively fitted onto the support rods at the corresponding scale lines. The vertical height of the four corners of the cylinder fixing plate can be adjusted by locking bolts, which makes it easy to adjust the level of the entire cylinder fixing plate according to the scale, so as to make it parallel to the transmission structure surface of the transmission device. Ultimately, the pressure plate driven by the pressure measuring cylinder is parallel to the transmission structure surface of the transmission device, and the pressure plate is guided by the guide rod to ensure that the pressure plate moves vertically up and down, thereby effectively ensuring that the pressure is uniform across the entire surface when the pressure plate is pressed down, and ensuring the accuracy and reliability of testing bagged products.

[0019] like Figure 1-3 As shown, a continuous bag pressure tester includes a transmission device 1 and a pressure plate 3 disposed above the transmission structure of the transmission device 1. A pressure sensor 4 is disposed on the upper surface of the pressure plate 3. The measuring end of the pressure sensor 4 is fixedly connected to the lower telescopic end of the pressure measuring cylinder 5 fixed above the transmission device 1.

[0020] Specifically: The top of the frame of the transmission device 1 is fixed with multiple vertical support rods 9. Each support rod 9 has vertically arranged scale lines 10 at its upper end. The four corners of the cylinder fixing plate 11 are respectively fitted onto the support rods 9 at the corresponding scale lines 10. The four corners of the cylinder fixing plate 11 are respectively provided with locking bolts for clamping and fixing the support rods 9. The pressure measuring cylinder 5 vertically passes through the cylinder fixing plate 11 and is fixedly connected to the cylinder fixing plate 11. Vertical guide rods 13 pass through the cylinder fixing plates 11 on both sides of the pressure measuring cylinder 5. The lower ends of the guide rods 13 on each side are fixedly connected to the upper surface of the pressure plate 3.

[0021] An L-shaped fixing plate 12 is provided on one side of the frame of the transmission device 1. A horizontal elongated fixing groove of the fixing plate 12 is used to fix an adjustable position sensor 2. The sensing end of the position sensor 2 corresponds to the transmission structure surface of the transmission device 1 directly below the pressure plate 3.

[0022] The transmission device 1 is a conveyor belt driven by a motor, and the conveyor belt is fixedly supported on the top of the frame of the transmission device 1. A power distribution box 7 is fixed inside the frame of the transmission device 1. A control panel 8 for controlling the operation of the pressure measuring cylinder 5 is set on one side of the top of the frame of the transmission device 1. Multiple arc-shaped bottom supports 6 are fixed at the bottom of the frame of the transmission device 1.

[0023] The working principle of this utility model is as follows: the bagged product is conveyed by the conveying device 1. The position sensor 2 detects that the object stops, the pressure cylinder 5 presses down, the pressure plate 3 contacts the product, the pressure sensor 4 feeds back the pressure data, and the pressure resistance of the product can be monitored and adjusted by the control panel 8. If the bagged product breaks or leaks during the pressure process, it is unqualified. After the product withstands the pressure, the pressure plate 3 rises back to the origin. The cycle continues in this manner. Data acquisition and uniform operation are controlled by the PLC software program of the control panel 8. The PLC software program is a conventional design by those skilled in the art.

[0024] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
