Description

Technical Field

[0001] The invention relates to the technical field of cardboard degumming limit testing devices, and in particular to a corrugated cardboard degumming limit testing device and a testing method. Background Art

[0002] In the production process of existing corrugated cardboard, it is necessary to bond and form it by gluing. In order to prevent the corrugated cardboard from easily separating and falling apart, it is necessary to use a compression tester to test the glue viscosity of the sample bonded by glue.

[0003] The working principle of the compression tester is to insert the needle-shaped accessory (peeling frame) between the fluted paper and the surface (back) paper of the sample (or between the fluted paper and the middle paper), and then apply pressure to the needle-shaped accessory (peeling frame) with the sample inserted to make it move relative to each other, and measure the maximum force required to separate the separated parts.

[0004] However, when faced with corrugated cardboards with different flute types, it is necessary to select needle accessories of different numbers and diameters. Since the number or diameter of needle accessories corresponding to each flute type of corrugated cardboard is different, the needle parts need to be replaced manually during testing, which makes storage and replacement more troublesome, time-consuming and labor-intensive. Summary of the invention

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A corrugated cardboard degumming limit testing device comprises a tester, wherein two mounting accessories are arranged in the tester, and a plurality of needle-type accessories are arranged on the two mounting accessories, and the needle-type accessories are arranged on the diameter adjustment mechanism and the quantity adjustment mechanism;

[0007] The diameter adjustment mechanism is used to adjust the diameter of the needle-type accessory;

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1 - Fig. 9 A corrugated cardboard degumming limit test device includes a tester 1. A positioning seat 2 and a pressing platform 3 are arranged in the tester 1. The positioning seat 2 is used to position and place the corrugated cardboard during the corrugated cardboard degumming test. The pressing platform 3 is used to provide pressure when the corrugated cardboard is degummed. The tester 1 is used to control and record the degumming process.

[0040] The positioning seat 2 is provided with a mounting attachment 5, and there are two mounting attachments 5, and a plurality of needle-type attachments 6 are installed on the two mounting attachments 5. The needle-type attachments 6 on the two mounting attachments 5 are arranged crosswise with each other and have different lengths. The needle-type attachment 6 with a long rod is used to limit the position of the corrugated cardboard, and the needle-type attachment 6 with a short rod is used to apply pressure to the corrugated cardboard, so that the bonding strength of the corrugated cardboard can be tested. The mounting attachment 5 is provided with a diameter adjustment mechanism 7, which is used to adjust the diameter of the needle-type attachment 6 to adapt to corrugated cardboards with different flute types.

[0041] See also Figure 6 - Figure 8 The diameter adjustment mechanism 7 includes a fixed rod 71, on which a plurality of fixed rings 72 are fixedly mounted, and the fixed rings 72 are evenly distributed in an array. A plurality of connecting rods 76 are rotatably mounted on the fixed ring 72, and the other ends of the connecting rods 76 are rotatably connected to a rotating frame 78, and the rotating frame 78 is slidably connected to the plug plate.

[0042] A plurality of sliding grooves 73 are provided on the fixed rod 71, and a control rod 74 is slidably installed on the fixed rod 71 through the sliding grooves 73. A plurality of control rings 75 are fixedly installed on the control rod 74, and a plurality of connecting rods 77 are rotatably installed on the control ring 75, and the other ends of the connecting rods 77 are rotatably connected to a rotating frame 78.

[0043] By moving the control rod 74, the control ring 75 is driven to move, and the control ring 75 squeezes the connecting rod 1 76 and the connecting rod 2 77 to rotate, and at the same time squeezes the rotating frame 78 to move along the plug board, so that the plug board can be driven to move stably, and all the plug boards have the same displacement distance, and all the plug boards are distributed in a circular array. The movement of the control rod 74 will not destroy the circular array, so that all the plug boards can still form a circle after displacement. A plurality of plug boards distributed in a circular array are combined together to form a needle-type attachment 6. The displacement of the plug board can be controlled by the displacement of the control rod 74, thereby controlling the diameter of the needle-type attachment 6, which is used to adapt to corrugated paperboards of different flute types.

[0044] See also Figure 5 and Fig. 9 One end of the control rod 74 is slidably connected to a connecting plate 79, and the mounting accessory 5 is provided with a groove, and the connecting plate 79 is slidably connected to the mounting accessory 5 through the groove, and an adjusting screw 1 710 is rotatably mounted on the mounting accessory 5. Preferably, there are two adjusting screws 1 710, and they are located at both ends of one side of the mounting accessory 5. The adjusting screw 1 710 is threadedly connected to the connecting plate 79,

[0045] Therefore, by synchronously rotating the two adjusting screws 710, the connecting plate 79 can be driven to move horizontally, thereby driving all the control rods 74 to move, and the displacement is more stable and smooth. The diameter of the needle-type attachment 6 can be adjusted by moving the control rod 74, thereby making it possible to synchronously adjust the diameters of all the needle-type attachments 6 on the installation attachment 5 at one time.

[0046] The mounting accessory 5 is provided with a plurality of slots 711, in which a clamping rod 712 is detachably mounted. Preferably, there are three slots 711, corresponding to the common E flute, C flute and B flute of the corrugated cardboard respectively. When the connecting plate 79 contacts the inside of the groove of the mounting accessory 5, it corresponds to the A flute. The connecting plate 79 is mounted in different slots 711 through the clamping rod 712. When the connecting plate 79 is displaced, the connecting plate 79 only needs to abut against the clamping rod 712, which means that the diameter of the needle-type accessory 6 is adjusted to the corresponding flute type, making it more convenient and quick to control the diameter of the corresponding needle-type accessory 6 for the common flute type.

[0047] See also Figure 6 , Figure 6 The images are of different diameters of the needle-type attachment 6, which are respectively adapted to the E flute, C flute, B flute and A flute of the corrugated cardboard from left to right.

[0048] See also Figure 2 - Figure 4 The mounting attachment 5 is also provided with a quantity adjustment mechanism 8 for adjusting the position of the needle attachment 6, thereby controlling the quantity of the needle attachment 6 inserted into the corrugated cardboard to adapt to the degumming detection of corrugated cardboards of different flute types.

[0049] The quantity adjustment mechanism 8 includes an adjustment groove 82, which is provided on the mounting attachment 5. A mounting ring 81 is slidably mounted in the adjustment groove 82. The mounting ring 81 is fixedly connected to one end of the fixing rod 71, so that the mounting ring 81 can drive the fixing rod 71 to move synchronously, thereby controlling the position of the needle-type attachment 6. At the same time, due to the sliding connection between the control rod 74 and the connecting plate 79, the connecting plate 79 will not affect the displacement of the fixing rod 71. An adjusting bolt No. 2 83 is rotatably mounted on the mounting ring 81. The adjusting bolt No. 2 83 penetrates the surface of the mounting accessory 5 and is threadedly connected to the mounting accessory 5, so that rotating the adjusting bolt No. 2 83 can drive the mounting ring 81 to move along the adjusting groove 82, and the mounting ring 81 drives the fixing rod 71 to move, and finally drives the needle-type accessory 6 to move, so that a single needle-type accessory 6 and other needle-type accessories 6 have a horizontal position difference. When other needle-type accessories 6 are inserted into the corrugated cardboard, the redundant needle-type accessories 6 in the shorter needle-type accessories 6 after adjustment are located below the corrugated cardboard and do not contact the corrugated cardboard, and will not affect the subsequent installation of the stripping frame 4. The redundant needle-type accessories 6 in the longer needle-type accessories 6 are located above the corrugated cardboard and do not contact the corrugated cardboard, and will not affect the support of the support rod 11 to the needle-type accessories 6.

[0050] See also Figure 2 The mounting accessory 5 with a longer needle-type accessory 6 can be mounted on a support 9, on which a support screw 10 is rotatably mounted. Preferably, there are two support screws 10, which are located on both sides of the top of the support 9. The support screw 10 is threadedly connected with a support rod 11. By controlling the synchronous rotation of the two support screws 10, the support rod 11 can be controlled to translate, so that the position of the support rod 11 can be adjusted, so that the support rod 11 can play a good supporting effect on needle-type accessories 6 of different diameters. The upper surface of the shorter needle-type accessory 6 contacts the stripping frame 4, so that uniform pressure can be applied to the stripping frame 4 to apply force to the needle-type accessory 6.

[0051] The present invention also provides a method for testing the degumming limit of corrugated paperboard, comprising the following steps:

[0052] Step 1: According to the flute type of the corrugated board, the diameter of the needle-type attachment 6 is adjusted by the diameter adjustment mechanism 7, and the clamping rod 712 can be clamped in different clamping slots 711 to quickly and accurately adjust the diameter of the needle-type attachment 6 corresponding to the common flute type, and the quantity adjustment mechanism 8 can be used to adjust the quantity of the needle-type attachment 6;

[0053] Step 2: insert two sets of needle-type accessories 6 crosswise into the corrugated cardboard to be tested;

[0054] Step 3: Clamp the installation accessory 5 into the support member 9 so that the bottom end of the longer needle-type accessory 6 is limited by the support rod 11 and the shorter needle-type accessory 6 is limited by the corrugated cardboard;

[0055] Step 4: placing the stripping frame 4 on the upper surface of the shorter needle-shaped attachment 6 to provide a stable and uniform pressure for the shorter needle-shaped attachment 6, and placing the support member 9 on the upper surface of the positioning seat 2;

[0056] Step 5: Start the tester 1 to move the press table 3 downward. When the press table 3 contacts the stripping frame 4, the shorter set of needle-type accessories 6 is pushed downward until the corrugated cardboard is separated under the limit of the longer set of needle-type accessories 6 and the push of the shorter set of needle-type accessories 6.

[0057] It should be noted that the present invention is a degumming limit testing device and a testing method for corrugated cardboard. When in use, the diameter and number of the corresponding needle-type attachments 6 are determined according to the flute type of the corrugated cardboard to be tested. The position of the mounting ring 81 is controlled by rotating the second adjusting bolt 83, thereby controlling the position of the needle-type attachments 6. The needle-type attachments 6 that do not need to be longer on the mounting attachment 5 are adjusted to the top of the other needle-type attachments 6, and the needle-type attachments 6 that do not need to be shorter on another mounting attachment 5 are adjusted to the bottom of the other needle-type attachments 6, so that the needle-type attachments 6 that need to be inserted on the same mounting attachment 5 are in a horizontal state.

[0058] According to the different flute types of the corrugated cardboard, by rotating the adjusting screw 710, the adjusting screw 710 drives the connecting plate 79 to move, thereby driving the control rod 74 to move, and the control ring 75 is driven to move by the movement of the control rod 74. The control ring 75 squeezes the connecting rod 1 76 and the connecting rod 2 77 to rotate, and at the same time squeezes the rotating frame 78 to move along the plug plate, thereby driving the plug plate to move stably, so that the diameter of the needle-type accessory 6 can be adjusted. If it is a common flute type, such as type A, type B, type C, and type E, it is only necessary to install the clamping rod 712 in the corresponding clamping groove 711, and the adjustment is completed when the connecting plate 79 moves to contact with the clamping rod 712. If it is an uncommon flute type, the diameter of the needle-type accessory 6 is measured to determine whether the adjustment is completed.

[0059] After the adjustment is completed, the two groups of needle-type accessories 6 are cross-inserted into the corrugated cardboard to be tested, and then the installation accessory 5 is installed on the support 9. The position of the support rod 11 is adjusted by rotating the support screw 10, so that the support rod 11 contacts one end of the lower surface of the longer needle-type accessory 6 to play a good supporting role, and the stripping frame 4 contacts the upper surface of the shorter needle-type accessory 6. Then the support 9 is placed on the positioning seat 2, and the tester 1 is started to move the pressing table 3 downward. The pressing table 3 contacts the stripping frame 4 to provide downward pressure for the shorter needle-type accessory 6 until the corrugated cardboard is separated under the limit of the longer group of needle-type accessories 6 and the push of the shorter group of needle-type accessories 6. At this time, the degumming limit test of the corrugated cardboard is completed.
