Description

Technical Field

[0001] The present invention relates to the technical field of high-pressure paper tube pressure resistance detection, and specifically to a pressure resistance detection device and a detection method for paper tube quality inspection based on high-pressure paper tube processing. Background Art

[0002] During the production process of high-pressure paper tubes, corresponding pressure-resistant detection devices are required to perform quality inspection on some paper tubes. A paper tube quality inspection machine with reference to publication number CN221377480U includes a workbench, and a detection component is arranged at the upper end of the workbench. The detection component includes a first electric push rod component respectively arranged on the left and right sides of the upper end of the workbench, which is beneficial to the accuracy of paper tube pressure detection and improves the quality inspection efficiency of paper tubes. As described in the above patent, when the existing pressure-resistant detection device for paper tube quality inspection based on high-pressure paper tube processing is used, most of them manually place the high-pressure paper tube required for quality inspection to the detection end, and manually remove the high-pressure paper tube after the detection is completed. This method has cumbersome operating steps when continuously detecting multiple groups of high-pressure paper tubes. It is easy to cause the high-pressure paper tube to be offset and misplaced during the continuous loading process, and then the position of the high-pressure paper tube needs to be adjusted back and forth, which makes it difficult to continuously load, detect and unload multiple groups of high-pressure paper tubes, affecting the detection efficiency.

[0016] Preferably, the unloading part includes a rotating plate rotatably connected to the workbench, the upper surface of the rotating plate is flush with the top of the workbench and is located at the lower side of the pressure plate, and a hydraulic cylinder assembly for adjusting the angle of the rotating plate is installed on the lower side of the workbench, and the workbench is installed with a support member for providing support for the rotating plate, and the support member includes a second cylinder horizontally arranged on the side of the workbench, and the extended end of the second cylinder is fixedly connected to a support block that fits with the lower end of the rotating plate, and the workbench is fixedly connected to a support frame that is slidably connected to the support block.

[0017] The present invention also discloses a detection method of a pressure-resistant detection device for paper tube quality inspection based on high-pressure paper tube processing, which specifically comprises the following steps:

[0018] Step 1: The user adjusts the spacing between the two sets of moving bars and the limiting bars through the first motor and the bidirectional screw rod so that the two can adapt to the required length of the high-pressure paper tube to be detected, and stores the high-pressure paper tube horizontally on the inclined surface of the frame, with the block providing support for the high-pressure paper tube. The user adjusts the height of the connecting frame and the block through the first cylinder so that the block is separated from the high-pressure paper tube. The high-pressure paper tube that loses support slides down the inclined surface of the frame under the action of gravity and falls between the two sets of moving bars on the workbench;

[0019] Step 2: In step 1, after the high-pressure paper tube falls on the upper side of the workbench, the second motor cooperates with the one-way screw to adjust the horizontal position of the extension plate and the push plate, and the push plate slides along the inner groove of the moving strip and pushes the high-pressure paper tube toward the pressing plate, so that the high-pressure paper tube contacts the limit block. At this time, the high-pressure paper tube is located on the rotating plate, so that the barrier is reset and the high-pressure paper tube to be inspected is stored on the upper surface of the frame again, so that the electric push rod assembly drives the pressing plate to press the high-pressure paper tube down for pressure resistance testing;

[0020] Step three: In step two, after the high-pressure paper tube inspection is completed, the push plate and the moving bar are reset, and the second cylinder with the support block is allowed to slide along the support frame. After the support block is separated from the bottom of the turn plate, the turn plate is driven to rotate by the hydraulic cylinder assembly, and the high-pressure paper tube slides down along the inclined surface of the turn plate to realize the unloading of the high-pressure paper tube that has completed the quality inspection, and each link in the unloading part is reset. Repeat the above steps to realize the continuity detection of the high-pressure paper tube.

[0021] Preferably, in step one, the two sets of limit strips prevent the high-pressure paper tube from deflecting during the sliding process of the high-pressure paper tube.

[0022] Beneficial Effects

[0023] The present invention provides a pressure-resistant detection device and a detection method for paper tube quality inspection based on high-pressure paper tube processing. Compared with the prior art, it has the following beneficial effects:

[0024] (1) The pressure-resistant testing device for paper tube quality inspection based on high-pressure paper tube processing, by arranging limiters and adjusting parts in the device, allows the first motor and the bidirectional screw to cooperate, and adjust the spacing between the two groups of moving bars and the limiter bars, respectively realizing the limitation of the high-pressure paper tubes stored on the frame and the high-pressure paper tubes retained on the workbench, and then playing an anti-drifting role in the process of high-pressure paper tube feeding and position adjustment, allowing the second motor, the unidirectional screw, the extension plate, and the push plate to cooperate with each other to realize the adjustment of the horizontal position of the high-pressure paper tube retained on the workbench, so that it moves to the lower end of the pressure plate, which is helpful for the subsequent pressure detection of the high-pressure paper tube.

[0025] (2) The pressure-resistant testing device for paper tube quality inspection based on high-pressure paper tube processing, by setting a barrier inside the device, allows an external loader to store the high-pressure paper tube horizontally on the inclined surface of the frame, and the block provides support for the high-pressure paper tube. The first cylinder adjusts the height of the connecting frame and the block to achieve the unloading and temporary storage of the high-pressure paper tube, which is helpful for the continuous detection of the high-pressure paper tube and improves the detection efficiency.

[0026] (3) The pressure-resistant testing device for paper tube quality inspection based on high-pressure paper tube processing has a material discharge part set in the device. After the high-pressure paper tube is inspected, the second cylinder adjusts the position of the support block to separate the support block from the bottom of the turn plate. The turn plate is driven to rotate by the hydraulic cylinder assembly. The high-pressure paper tube slides down along the inclined surface of the turn plate and falls into the recycling box at the bottom of the workbench through the material discharge chute, thereby realizing the recycling of the high-pressure paper tube that has been inspected, facilitating the rapid discharge of the high-pressure paper tube that has been inspected, and avoiding affecting the subsequent loading of the high-pressure paper tube to be inspected.

[0043] The material discharging member 8 comprises a rotating plate 81 rotatably connected to the workbench 1, the upper surface of the rotating plate 81 is flush with the top of the workbench 1 and is located at the lower side of the pressing plate 3, a material discharging trough is vertically provided on the side of the workbench 1 close to the rotating plate 81, a hydraulic cylinder assembly 82 for adjusting the angle of the rotating plate 81 is installed at the lower side of the workbench 1, the workbench 1 is installed with a support member 83 for providing support for the rotating plate 81, the support member 83 comprises a second cylinder 831 horizontally arranged on the side of the workbench 1, the extended end of the second cylinder 831 is fixedly connected to a support block 832 abutting against the lower end of the rotating plate 81, and the workbench 1 is fixedly connected to a support frame 833 slidably connected to the support block 832;

[0044] A recycling box is placed on the lower side of the workbench 1 near the left side of the rotating plate 81. The fixed end of the hydraulic cylinder in the hydraulic cylinder assembly 82 is rotatably connected to the workbench 1, and the extended end of the hydraulic cylinder is rotatably connected to the lower side of the rotating plate 81. A square groove slidably connected to the support block 832 is provided in the support frame 833; the support frame 833 cooperates with the support block 832 to provide support for the rotating plate 81.

[0045] The present invention also discloses a detection method of a pressure-resistant detection device for paper tube quality inspection based on high-pressure paper tube processing, which specifically comprises the following steps:

[0046] Step 1: The user starts the first motor 41, and the first motor 41 drives the two groups of moving bars 43 and the limit bars 45 to move in the opposite direction through the bidirectional screw 42, so that the distance between the two groups of moving bars 43 and the limit bars 45 is slightly larger than the required length of the high-pressure paper tube to be detected, and the external feeder stores the high-pressure paper tube horizontally on the inclined surface of the frame 5, and the block 63 provides support for the high-pressure paper tube.

[0047] Step 2: In step 1, after the high-pressure paper tube falls on the upper side of the workbench 1, the second motor 71 cooperates with the one-way screw 72 to adjust the horizontal positions of the extension plate 73 and the push plate 74, and the push plate 74 slides along the inner groove of the moving bar 43 and pushes the high-pressure paper tube toward the pressing plate 3. After the high-pressure paper tube contacts the limit block 44, the adjustment of the position of the push plate 74 is stopped. At this time, the high-pressure paper tube is located on the rotating plate 81, so that the barrier 6 is reset and the subsequent high-pressure paper tube to be inspected is stored on the upper surface of the frame 5 again, so that the two groups of moving bars 43 are in contact with both sides of the high-pressure paper tube, and the electric push rod assembly 2 is started, so that the electric push rod assembly 2 drives the pressing plate 3 to press down the high-pressure paper tube, and the pressure sensor on the lower side of the pressing plate 3 detects the pressure to realize the pressure resistance test of the high-pressure paper tube. This is the prior art, and the specific structure and working principle of the pressing plate 3 are not repeated here.

[0048] Step three: in step two, after the high-pressure paper tube inspection is completed, the push plate 74 and the moving bar 43 are reset, and the second cylinder 831 is allowed to slide along the support frame 833 with the support block 832. After the support block 832 is separated from the bottom of the rotating plate 81, the rotating plate 81 is driven to rotate by the hydraulic cylinder assembly 82. The high-pressure paper tube slides down along the inclined surface of the rotating plate 81 and falls into the recycling box at the bottom of the workbench 1 through the discharge chute, realizing the recycling of the high-pressure paper tube that has completed the quality inspection, and then the various links in the discharge part 8 are reset, and the above steps are repeated to realize the continuity detection of the high-pressure paper tube.

[0049] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art. In step 1, the two sets of limit strips 45 prevent the high-pressure paper tube from deflecting during its sliding process.

[0050] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
