[0026] like Figure 1 , Figure 3-6 and Fig. 9 As shown:

[0027] A plastic film processing device comprises a fixed rod 101, a fixed seat 301 and a T-bar 603, wherein a connecting rod 104 is fixedly connected to the fixed rod 101, a sliding part 102 is slidably connected to the fixed rod 101, a test rod 103 is fixedly connected to the sliding part 102, a test part 302 is slidably connected to the fixed seat 301, a test pressure rod 401 is slidably connected to the test part 302, a first compression spring is arranged between the test part 302 and the test pressure rod 401, a second compression spring is fixedly connected between the fixed seat 301 and the test part 302, and a T-bar A moving part 601 is slidably connected to 603, a rotating rod 602 is rotatably connected to the moving part 601, a cylindrical rod 303 is fixedly connected to the testing part 302, the rotating rod 602 can contact the cylindrical rod 303, a first electric push rod that can push the moving part 601 to slide is fixedly connected to the T-bar 603, a first motor that can drive the rotating rod 602 to rotate is fixedly connected to the moving part 601, the elastic force of the first compression spring makes the testing pressure rod 401 keep the tendency to slide downward, and the elastic force of the second compression spring makes the testing part 302 keep the tendency to slide upward.

[0028] The formed plastic film roll is sleeved on the connecting rod 104 and fixed, and then one end of the plastic film roll is fixed on the test rod 103, and the plastic film between the test rod 103 and the connecting rod 104 is in a tensioned state. At this time, the test pressure rod 401 is in a position that can contact the front side of the sliding part 102, and then the rotating rod 602 is operated to rotate on the moving part 601, and then the rotating rod 602 is used to move the cylindrical rod 303 to make the test part 302 slide downward on the fixed seat 301. During the downward sliding process of the test part 302, the test The test pressure rod 401 on the test part 302 will continue to contact with the sliding part 102. During this process, if the molding quality of the plastic film is good and the tensile strength is strong, the test pressure rod 401 will overcome the elastic force of the first compression spring and adaptively slide upward in the vertical direction relative to the test part 302 on the test part 302 until the rotating rod 602 rotates to a position separated from the cylindrical rod 303. If the test pressure rod 401 always follows the sliding of the test part 302 and adaptively slides on the test part 302, it proves that the tensile strength of the plastic film meets the factory standard.

[0029] If the test pressure rod 401 does not adaptively slide on the test part 302 during the rotation of the rotating rod 602, or the test pressure rod 401 adaptively slides at one end and then slides synchronously with the test part 302, it proves that after the first compression spring provides a certain elastic force, it will directly press the sliding part 102 to slide on the fixed rod 101, thereby causing the surface of the plastic film to be stretched and deformed in the horizontal direction. At this time, it proves that the tensile strength of the plastic film does not meet the factory standard, that is, it proves that the molding effect of the plastic film being tested at this time is not perfect, and it needs to be reprocessed or discarded, so as to ensure the finished product effect of the factory finished product;

[0030] During actual use, the staff can operate the moving part 601 to slide to different positions on the T-bar 603 according to different testing needs, and then use the rotating rod 602 to rotate the cylindrical rod 303. By sliding the moving part 601, the distance between the moving part 601 and the cylindrical rod 303 can be changed, and then the rotating rod 602 can change the sliding distance of the cylindrical rod 303, and then the distance that the test part 302 can slide down during each test can be changed, so that the elastic force that the first compression spring can provide during the test can be changed, and then the plastic film can be subjected to different tensile strength tests according to different testing standards to meet actual testing needs.

[0031] like Figure 3-5 As shown:

[0032] It also includes a connecting piece A304 detachably connected to the test part 302 by bolts, a connecting piece B402 detachably connected to the test pressure rod 401 by bolts, and a first compression spring is fixed between the connecting piece A304 and the connecting piece B402.

[0033] The setting of the connecting piece A304 and the connecting piece B402 allows the staff to remove the connecting piece A304 and the connecting piece B402 by loosening the bolts when using the equipment for inspection. Then, the connecting piece A304 and the connecting piece B402 can be replaced with the first compression spring with larger or smaller elastic force in the equipment, thereby further facilitating the meeting of different actual inspection needs.

[0034] like Figure 5-7 As shown:

[0035] It also includes a slider 504 connected to the fixed seat 301, the slider 504 is slidably connected to an auxiliary rod 501, the auxiliary rod 501 is slidably connected to a toggle rod 502, the auxiliary rod 501 is fixedly connected to a second electric push rod capable of pushing the toggle rod 502 to slide, and the test part 302 is fixedly connected to an electromagnetic block capable of adsorbing the test pressure rod 401.

[0036] When the test pressure rod 401 is used to slide down to test the tensile strength of the plastic film, the toggle rod 502 is slid to a position staggered with the cylindrical rod 303 to ensure that the cylindrical rod 303 slides down without interfering with the toggle rod 502. When the tensile strength test operation is completed, the electromagnetic block is energized to firmly fix the test part 302 and the test pressure rod 401. Then, the auxiliary rod 501 is continuously slid upward until the toggle rod 502 is higher than a certain height position of the cylindrical rod 303. Then, the toggle rod 502 is operated to slide on the auxiliary rod 501 so that the toggle rod 502 overlaps with the cylindrical rod 303. Then, the auxiliary rod 501 is quickly slid downward so that the toggle rod 502 quickly contacts with the cylindrical rod 303 and slaps the cylindrical rod 303 downward, so that the test pressure rod 401 strongly pushes the sliding part 102, and then the sliding part 102 strongly pulls the plastic film, thereby testing the tear resistance of the plastic film, further enriching the detection effect of the present device.

[0037] like Figure 5 As shown:

[0038] It also includes a driving part 701, on which a slide rail 702 is slidably connected, on which an adjustment block 704 is slidably connected, on which the adjustment block 704 is connected a contact inclined rod 705, on which the auxiliary rod 501 is fixedly connected a contact rod 503, on which a third electric push rod capable of driving the slide rail 702 to slide is fixedly connected the driving part 701, on which a third electric push rod capable of driving the adjustment block 704 to slide is fixedly connected the slide rail 702, and a third compression spring is fixedly connected between the auxiliary rod 501 and the slider 504.

[0039] When it is necessary to operate the auxiliary rod 501 to slide upward, the adjusting block 704 will continue to slide on the slide rail 702. During this process, the contact inclined rod 705 will gradually contact the contact rod 503, thereby gradually pushing the auxiliary rod 501 to slide upward. When the adjusting block 704 slides to the point where the contact inclined rod 705 is separated from the contact rod 503, the auxiliary rod 501 will be subjected to the elastic force of the third compression spring and slide downward quickly, causing the toggle rod 502 to collide with the cylindrical rod 303 and then perform a knocking operation, thereby completing the tear resistance test operation of the plastic film. When it is necessary to reset the contact inclined rod 705 to the position where the contact rod 503 is not moved, the operating slide rail 702 is operated to slide on the driving part 701, so that the contact inclined rod 705 is staggered with the contact rod 503, and then the operating adjustment block 704 is operated to slide in the opposite direction until the adjustment block 704 is reset to the unmoved position, and then the slide rail 702 is slid again to move the contact inclined rod 705 to the lower side of the cylindrical rod 303, providing convenience for the subsequent re-toggle operation.

[0040] like Figure 8 As shown:

[0041] The contact inclined rod 705 is rotatably connected to the adjustment block 704 , and a second motor capable of driving the contact inclined rod 705 to rotate is fixedly connected to the adjustment block 704 .

[0042] In actual use, the contact inclined rod 705 can be operated to rotate on the adjustment block 704 to adjust the inclination angle of the contact inclined rod 705, thereby changing the height to which the auxiliary rod 501 is lifted during the detection process, thereby providing the plastic film with tear resistance detection effects of different strengths, further bringing convenience to the actual detection operation.

[0043] like Figure 6 As shown:

[0044] The slider 504 is slidably connected to the fixing seat 301 , and a fourth electric push rod capable of pushing the slider 504 to slide is fixedly connected to the fixing seat 301 .

[0045] Before conducting the tensile strength test, first operate the slider 504 to slide on the fixed seat 301, so that the toggle rod 502 moves to a position where it can just contact the upper side of the cylindrical rod 303, and then slide the adjustment block 704 and use the auxiliary rod 501 that slides upward to complete the subsequent tapping operation. The sliding connection setting between the slider 504 and the fixed seat 301 enables the toggle rod 502 to adapt to the cylindrical rod 303 at different heights to perform a force-accumulating tapping operation.

[0046] like Figure 2 As shown:

[0047] It also includes a matching seat 201, a sliding frame 202 is slidably connected to the matching seat 201, a cutter 203 is fixedly connected to the sliding frame 202, and a fifth electric push rod is fixedly connected to the matching seat 201 and can push the sliding frame 202 to slide downward.

[0048] After the test is completed, the sliding frame 202 can be operated to continue to slide downward, so that the cutter 203 on the sliding frame 202 contacts the surface of the plastic film, and the plastic film is cut by the cutter 203, thereby cutting the plastic film just used in the test process, so as to avoid the test process affecting the performance of the plastic film, thereby affecting the subsequent sales of the plastic film.

[0049] As shown in 2:

[0050] It also includes a sliding seat 204 slidably connected to the sliding frame 202, two imprint cottons 205 are fixedly connected to the sliding seat 204, and the two imprint cottons 205 are impregnated with pigments of different colors. The sliding frame 202 is fixedly connected to a sixth electric push rod capable of pushing the sliding seat 204 to slide.

[0051] When the sliding frame 202 is used to slide down and cut the plastic film, the marking cotton 205 on the sliding frame 202 will contact the plastic film roll, leaving a pigment mark on the plastic film roll, thereby marking the plastic film roll that has completed the inspection, providing convenience for subsequent unified collection work;

[0052] If the plastic film roll passes the tensile strength test, the sliding seat 204 is slid to Figure 2 The posture shown leaves only a single pigment mark on the plastic film roll. If the plastic film roll fails the tensile strength test, the sliding seat 204 slides on the sliding frame 202, leaving two colors of pigment marks on the plastic film roll, which brings convenience for subsequent use.

[0053] like Figure 8-9 As shown:

[0054] It also includes a detection head 703 slidably connected to the slide rail 702 , a rectangular rod 206 is fixedly connected to the slide seat 204 , and a fourth compression spring is fixedly connected between the slide rail 702 and the detection head 703 .

[0055] Before using the sliding frame 202 to slide downward for cutting, the slide rail 702 can be operated to slide on the driving part 701 to make the detection head 703 slide toward the direction close to the rectangular rod 206. At this time, if the rectangular rod 206 should be in the overlapping position with the leftmost side of the sliding frame 202, the detection head 703 will not slide adaptively on the slide rail 702. At this time, if the detection head 703 slides, it proves that the power source driving the sliding seat 204 to slide is faulty. At this time, it is necessary to stop the equipment in time to avoid pigment marking deviation, which will cause confusion in subsequent processing.

[0056] The plastic film processing equipment is used in a method for processing a plastic film, the method comprising the following steps:

[0057] Step 1: Sleeve the formed plastic film roll on the connecting rod 104 and fix the plastic film roll, and then fix one end of the plastic film roll on the test rod 103;

[0058] Step 2: Make the moving part 601 slide on the T-shaped rod 603, and then operate the rotating rod 602 to rotate on the cylindrical rod 303;

[0059] Step 3: energize the electromagnetic block and then slide the auxiliary rod 501 upward;

[0060] Step 4: slide the toggle rod 502 on the auxiliary rod 501, and then continue to slide the adjustment block 704 on the slide rail 702;

[0061] Step 5: operate the sliding frame 202 to slide on the matching seat 201, and then take down the plastic film rolled on the connecting rod 104 to complete the processing.
