Description

Technical Field

[0001] The invention relates to the technical field of detection devices, and in particular to a detection device for a finished polypropylene film product. Background Art

[0002] After the finished polypropylene film is produced, the quality of the batch of polypropylene film needs to be tested to prevent unqualified polypropylene film from entering the market, among which tension stretching test is particularly important.

[0003] The patent announcement number CN215866115U discloses a tension stretching detection device for polypropylene film production, including a workbench, a clamping structure and a lifting structure. The clamping structure is fixedly connected to both sides of the upper end of the workbench. During the detection, the film is first clamped and fixed using the clamping structure, and then the two ends of the clamped film can be stretched synchronously through the synchronous transmission structure to increase the tensioning effect of the film. Subsequently, the film can be lifted upward from the middle of the lower end of the film through the lifting structure. At this time, the film tension coefficient can be obtained in conjunction with the scale lines on the detection plate, and the tension stretching detection of the film can be completed in this way.

[0004] When the detection device of the above patent performs tension stretching detection on polypropylene film, it only relies on the lifting structure to lift the film upward from the middle of the lower end of the film for detection. Since the force used by the lifting structure to lift the middle of the film upward is different from the force used to lift other parts of the film upward, if only the middle of the film is pushed upward, the detection accuracy is low and there are errors in the detection data.

DETAILED DESCRIPTION

The left part of the first threaded rod 32 is rotatably connected to the frame 1, and the upper rear part of the frame 1 is also rotatably connected to the first threaded rod 32. The transmission belt 33 is wound between the right parts of the two first threaded rods 32 through the transmission wheel. The first movable frame 34 is threadedly connected between the first threaded rods 32. The lower part of the first movable frame 34 is slidably connected to the frame 1. The front and rear parts of the upper side of the first movable frame 34 are both rotatably connected to the threaded column 36, and the front and rear parts of the upper left side of the frame 1 are also rotatably connected to the threaded column 36. There are two pressure blocks 35, and the two pressure blocks 35 are respectively threadedly connected between two vertically aligned threaded columns 36.

[0044] like Figure 1 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the pressure detection mechanism 4 includes a limit barrel 41, a placement rack 42, a limit rod 43, a first telescopic rod 44, a block 45, a second telescopic rod 46, a second movable rack 47, a limit frame 49, a pin lock 412 and an observation component. The limit frame 49 is connected to the upper side of the rear portion of the rack 1, and the second movable rack 47 is slidably connected in the limit frame 49. The second telescopic rod 46 is connected to the upper front side of the second movable rack 47. The front of the second telescopic rod 46 is connected to the limit barrel 41, the limit rod 43 is connected to the front of the limit barrel 41, the placement rack 42 is slidably connected to the limit rod 43, the placement rack 42 and the limit barrel 41 are slidably connected, the first telescopic rod 44 is connected to the upper right side of the limit barrel 41, the block 45 is connected to the left side of the first telescopic rod 44, the upper side of the block 45 is against the front and lower side of the placement rack 42, the pin lock 412 is installed on both the front and rear sides of the lower portion of the second movable rack 47, and an observation component is provided on the second movable rack 47.

[0045] like Figure 6 , Figure 7 , Figure 8 and Fig. 9As shown, the observation assembly includes a first multi-stage telescopic member 48, a second multi-stage telescopic member 411 and a first scale plate 410. The first scale plate 410 is connected to the rear side of the lower right part of the second movable frame 47. The number of the second multi-stage telescopic members 411 is two. The two second multi-stage telescopic members 411 are respectively installed on the left and right sides of the lower part of the second movable frame 47. The first multi-stage telescopic member 48 is connected between the upper sides of the second multi-stage telescopic member 411.

[0046] When people need to perform tension stretching test on the finished polypropylene film 2, the finished polypropylene film 2 testing device can be used to operate it. First, the threaded column 36 is rotated, and then the pressure block 35 is driven to move upward, and then the polypropylene film 2 wound on the upper left part of the frame 1 is pulled to the right. At this time, the pulled polypropylene film 2 will pass under the pressure block 35. When the polypropylene film 2 is pulled to the right of the pressure block 35 on the right, the pulling of the polypropylene film 2 is stopped, and then the two threaded columns 36 on the left are manually rotated in the opposite direction to drive the pressure block 35 on the left to move downward, so that the pressure block 35 on the left presses the left part of the pulled polypropylene film 2, and then the pulled polypropylene film 2 is pulled to a taut state, and then the two threaded columns on the right are manually rotated in the opposite direction. The column 36 rotates in the opposite direction, driving the pressure block 35 on the right to move downward, so that the pressure block 35 on the right presses the right part of the pulled polypropylene film 2, and then the motor 31 is turned on again, so that the output shaft of the motor 31 drives the first threaded rod 32 on the front side to rotate, and then drives the first threaded rod 32 on the rear side to rotate through the transmission belt 33. At this time, the two first threaded rods 32 will drive the first moving frame 34 to drive the pressure block 35 on the right to move right, so that the film can be automatically pulled. When the first moving frame 34 moves to the right to the destination, the output shaft of the motor 31 is controlled to stop rotating. Then, people can derive the tension coefficient of the polypropylene film 2 according to the deformation degree of the film. If the tension coefficient is a standard value, it means that the polypropylene film 2 is qualified. If there is a large difference between the number and the standard value, it means that the polypropylene film 2 is unqualified, and then the output shaft of the motor 31 is controlled to drive the first threaded rod 32 and the transmission belt 33 to rotate in the opposite direction, so that the first threaded rod 32 drives the first movable frame 34 and the pressure block 35 on the right to move to the left, and then the pressure block 35 is driven to move upward, so that the pressure block 35 no longer presses the tested polypropylene film 2, and then the tested polypropylene film 2 is cut off, and then the remaining polypropylene film 2 on the upper left part of the frame 1 is manually pulled out to the right again, and the pressure block 35 is moved downward to fix the polypropylene film 2 pulled out again, and then a standard weight block is manually added to the limit barrel 41. At this time, the weight block will be located on the upper rear side of the placement frame 42. When the weight block After placement is completed, the block 45 is manually moved to the right, and then the first telescopic rod 44 contracts. When the block 45 moves to the right away from the front lower side of the placement frame 42, the counterweight block will press the placement frame 42 downward, and then the placement frame 42 will push the polypropylene film 2 below downward. At this time, the middle part of the polypropylene film 2 will deform and sink. When the polypropylene film 2 is deformed to the limit and no longer sinks rapidly, in order to avoid the polypropylene film 2 from breaking, people can manually move the placement frame 42 upward, then take out the counterweight block on the placement frame 42, and then manually move the block 45 to the left, so that the block 45 is against the front lower side of the placement frame 42 again, and then the first telescopic rod 44 is stretched, and then the first multi-stage telescopic member 48 is manually moved downward.Then the second multi-stage telescopic member 411 performs a contraction movement. When the first multi-stage telescopic member 48 moves downward to be flush with the bottom of the polypropylene film 2, the first multi-stage telescopic member 48 stops moving. At this time, people can obtain the distance that the polypropylene film 2 sinks according to the position indicated by the first multi-stage telescopic member 48 on the first scale plate 410. Then people calculate the tension coefficient of the polypropylene film 2 based on the obtained data. After people have recorded the distance that the polypropylene film 2 sinks, they manually move the first multi-stage telescopic member 48 upward, and then the second multi-stage telescopic member 411 performs an extension movement. When people need to squeeze different positions on the polypropylene film 2 during the detection process, they directly adjust the front, back, left and right positions of the limit barrel 41. That is, when people need to adjust the front and rear position of the limit barrel 41, they can directly telescope the second telescopic rod 46, so that the front and rear position of the limit barrel 41 can be adjusted. When people need to adjust the left and right position of the limit barrel 41, they can directly manually move the limit barrel 41, the second telescopic rod 46 and the second mobile frame 47 left and right, so that the left and right position of the limit barrel 41 can be adjusted. When the second mobile frame 47 moves to the destination, the pin lock 412 can fix the second mobile frame 47 to improve the stability of the second mobile frame 47 on the limit frame 49. In summary, a variety of detection methods can be used to perform tension stretching detection on the finished polypropylene film 2, thereby improving the detection accuracy.

[0047] Embodiment 2: Based on embodiment 1, Figure 1 , Fig.10 , Fig.11 and Fig.12 As shown, a display mechanism 5 is also included, and the display mechanism 5 includes a fixed rod 51, an erasable marker pen 52, a second scale plate 53 and a blackboard 54. The second scale plate 53 is connected to the upper left front side of the frame 1, and the blackboard 54 is connected to the rear side of the second scale plate 53. The fixed rod 51 is connected to the left front side of the pressure block 35 on the right side, and the erasable marker pen 52 is connected to the left part of the fixed rod 51. The lower side of the erasable marker pen 52 is in contact with the upper side of the blackboard 54.

[0048] When people perform tension stretching detection on the polypropylene film 2 by pulling the polypropylene film 2 horizontally, they can use the display mechanism 5 to operate. When the first movable frame 34 moves to the right, the first movable frame 34 will also drive the fixed rod 51 and the erasable marker 52 to move to the right. At this time, the erasable marker 52 will draw a straight line on the blackboard 54. Then, when the first movable frame 34 moves to the destination and stops moving, the fixed rod 51 and the erasable marker 52 will also stop moving. Then, people can obtain the stretching distance of the polypropylene film 2 according to the distance of the straight line drawn by the erasable marker 52, so that it can be intuitively obtained. The stretching distance of the polypropylene film 2 is known. When the polypropylene film 2 suddenly breaks during the pulling process, the first movable frame 34, the fixed rod 51 and the erasable marker 52 are immediately controlled to stop moving. At this time, people can intuitively know how much the polypropylene film 2 breaks after being stretched based on the drawn straight line, so that it is convenient for people to improve the polypropylene film 2 later. Subsequently, when the first movable frame 34 moves to the left, the first movable frame 34 will also drive the fixed rod 51 and the erasable marker 52 to move to the left, and then the straight line drawn on the blackboard 54 will be erased. In summary, the stretching distance of the polypropylene film 2 can be assisted.

[0049] like Figure 1 , Fig.13 , Fig.14 , Fig.15 and Fig.16 As shown, it also includes an extreme stability mechanism 6, which includes a connecting block 61, a third multi-stage telescopic member 62, a fourth multi-stage telescopic member 63, a moving block 64, a first limit frame 65, a limit member 66, a top plate 67, a compression member 68, a second limit frame 69 and a support rod 610. The connecting block 61 is connected to the front side of the upper part of the placement frame 42, the front side of the connecting block 61 is connected to the third multi-stage telescopic member 62, the fourth multi-stage telescopic member 63 is connected to the front lower side of the third multi-stage telescopic member 62, the moving block 64 is connected to the lower side of the fourth multi-stage telescopic member 63, the lower side of the right rear part of the moving block 64 is an inclined surface, and the front and rear parts of the upper left side of the frame 1 are both connected to the second The limiting frame 69, the first limiting frame 65 is connected to the front side of the upper left part of the second limiting frame 69 on the front side, the first limiting frame 65 and the moving block 64 are clamped, the lower front side of the second moving frame 47 is connected with the support rod 610, the compression member 68 is connected to the front of the support rod 610, the compression member 68 is located directly below the limiting barrel 41, the compression member 68 has a linear spring, the upper side of the compression member 68 is connected to the top plate 67, the limiting member 66 is slidably connected between the upper part of the second limiting frame 69, the lower side of the limiting member 66 is against the upper side of the top plate 67, the upper front side of the limiting member 66 is tilted toward the lower left, and the upper front side of the limiting member 66 and the lower right rear side of the moving block 64 are squeezed together.

[0050] When the polypropylene film 2 is being tested, the placement rack 42 and the counterweight block squeeze the polypropylene film 2 downward to the target value. In order to prevent the placement rack 42 and the counterweight block from continuing to press the polypropylene film 2 downward and causing the polypropylene film 2 to break, the limit stability mechanism 6 can be used. Initially, the linear spring in the compression member 68 is in a compressed state. When the placement rack 42 moves downward, the placement rack 42 will also drive the connecting block 61, the third multi-stage telescopic member 62, the fourth multi-stage telescopic member 63 and the moving block 64 to move downward. When the polypropylene film 2 is squeezed downward to the target value and the moving block 64 also contacts the front upper side of the limiting member 66, At this time, the moving block 64 will squeeze the limiting member 66 to the right. When the limiting member 66 moves to the right away from the top plate 67, under the action of the linear spring in the compression member 68, the compression member 68 will extend and then drive the top plate 67 to move upward, so that the top plate 67 pushes the placement frame 42 and the counterweight block upward, thereby preventing the polypropylene film 2 from being squeezed and broken. After the top plate 67 pushes the placement frame 42 and the counterweight block upward, people manually move the placement frame 42 upward and fix it, and take out the counterweight block on the placement frame 42. At this time, the placement frame 42 will also drive the connecting block 61, the third multi-stage telescopic member 62, and the fourth multi-stage telescopic member 63. 63 and the moving block 64 move upward, and the moving block 64 no longer squeezes the limiting member 66. After the moving block 64 moves upward and resets, people need to continue to move the placement rack 42 upward. When taking out the counterweight block, the placement rack 42 will continue to drive the connecting block 61 and the third multi-stage telescopic member 62 to move upward, and then the fourth multi-stage telescopic member 63 will extend. After the counterweight block is taken out, when the placement rack 42 moves downward, first hold the moving block 64 by hand, and then when the placement rack 42 drives the connecting block 61 and the third multi-stage telescopic member 62 to move downward, the fourth multi-stage telescopic member 63 will retract, and then manually move the top plate 67 downward. Then the compression member 68 performs a contraction movement, at which time the linear spring in the compression member 68 will also be compressed, and then the limit member 66 is manually moved to the left and reset, so that the limit member 66 rests against the top plate 67 again, and then people can record the distance that the polypropylene film 2 sinks downward, and when people need to adjust the front and rear position of the limit barrel 41, the limit barrel 41 will also drive the placement frame 42 and the connecting block 61 to move forward and backward, and then the third multi-stage telescopic member 62 performs a telescopic movement, which will not affect the front and rear movement of the limit barrel 41. In summary, the polypropylene film 2 can be prevented from being squeezed to break during the detection process.

[0051] like Figure 1 , Fig.17 and Fig.18As shown, it also includes an environmental simulation mechanism 7, which includes a fifth multi-stage telescopic member 71, a support frame 72, a controller 73 and a heating wire 74. The support frame 72 is connected to the upper rear side of the limiting barrel 41, the upper part of the support frame 72 is connected to the fifth multi-stage telescopic member 71, the heating wire 74 is connected to the lower part of the fifth multi-stage telescopic member 71, the lower side of the heating wire 74 is connected to the upper rear side of the placement frame 42, the controller 73 is connected to the upper rear side of the limiting barrel 41, the controller 73 is electrically connected to the heating wire 74 through an electric wire, and the electric wire slides through the limiting barrel 41.

[0052] When people need to detect the tension coefficient of the polypropylene film 2 when it is used in an environment with a high temperature, the environmental simulation mechanism 7 can be used for operation. First, the controller 73 is turned on, and then the heating wire 74 is energized through the controller 73, so that the heating wire 74 heats the placement rack 42 and the counterweight block. This can simulate the use of the polypropylene film 2 under high temperature conditions. When the placement rack 42 moves up and down, the placement rack 42 will also drive the lower side of the heating wire 74 to move up and down, and then the fifth multi-stage telescopic member 71 performs a telescopic movement, so that the heating wire 74 can continue to heat the placement rack 42 and the counterweight block. When the detection is completed, the controller 73 can be turned off. In summary, different scenarios can be simulated to detect the polypropylene film 2.

[0053] like Figure 1 , Fig.19 and Fig. 20 As shown, an auxiliary mechanism 8 is also included, and the auxiliary mechanism 8 includes a support member 81, a pressure plate 82, a compression spring 83 and a second threaded rod 84. The second threaded rod 84 is rotatably connected to the upper right side of the frame 1, the support member 81 is threadedly connected to the second threaded rod 84, the lower part of the support member 81 is slidably connected to the frame 1, the pressure plate 82 is slidably connected to the upper part of the support member 81, and compression springs 83 are connected between the front and rear parts of the upper side of the pressure plate 82 and the support member 81, and the compression springs 83 are all wound around the support member 81.

[0054] When people pull out the polypropylene film 2 wound on the upper left part of the frame 1 to the right, the auxiliary mechanism 8 can be used to help people fix the pulled out polypropylene film 2. First, manually pull the pressure plate 82 upward, and the compression spring 83 is compressed. Then people can pull the polypropylene film 2 wound on the upper left part of the frame 1 to the right, and pass the pulled out polypropylene film 2 through the lower side of the pressure plate 82. After people press the left part of the pulled out polypropylene film 2 and pull the polypropylene film 2 to be tight, release the pressure plate 82. Under the action of the compression spring 83, the pressure plate 82 will move downward to press the right part of the polypropylene film 2. Then people manually turn the threaded column 36 on the right to drive The pressure block 35 on the right side is moved downward to press the right part of the polypropylene film 2. When the pressure block 35 on the right side presses the right part of the polypropylene film 2, the pressure plate 82 is manually pulled upward, and then the second threaded rod 84 is manually rotated to drive the second threaded rod 84 to drive the support member 81 and the pressure plate 82 to move rightward, so that the pressure plate 82 moves to the right away from the polypropylene film 2. When the pressure plate 82 moves to the right away from the polypropylene film 2, people can release the pressure plate 82. When the detection is completed, people manually rotate the second threaded rod 84 in the opposite direction, so that the second threaded rod 84 drives the support member 81 and the pressure plate 82 to move to the left. In summary, the above can help people fix the pulled out polypropylene film 2.
