Description

Technical Field

[0001] The invention relates to the technical field of printing material detection, and in particular to a printing material detection mechanism and a printing press having the detection mechanism. Background Art

[0002] Printing materials refer to various substances used in the printing process, including paper, ink, cloth, etc. When printing on cloth, the physical and chemical properties of the cloth must also be tested. When conducting a tensile test on the cloth, it is generally done through a tensile testing machine or by directly placing the cloth sample on a test fixture to apply uniform tension.

[0003] However, whether it is a dedicated tensile testing machine or a test fixture, it needs to be clamped before testing. If a tensile test is performed on a test sample that is too large, the steps are a bit cumbersome and increase the labor burden of the staff, which ultimately leads to low test efficiency. Especially when performing segmented testing on a roll of cloth, the existing testing agencies cannot meet the testing efficiency that people want, and a product with higher testing efficiency is urgently needed.

DETAILED DESCRIPTION

Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0037] See also Figure 1-Figure 3 , Figure 7A printing material detection mechanism includes a detection box 1 and a plurality of pairs of transport rollers 2 movably arranged inside the detection box 1, wherein the two ends of the transport rollers 2 are respectively fixedly connected with a first rotating shaft 3 and a second rotating shaft 4, wherein a pair of transport rollers 2 are provided with a transmission component 5, the transmission component 5 includes a first driving disk 51 and a second driving disk 52, the second driving disk 52 is fixedly sleeved on the outer end of the second rotating shaft 4, when the first driving disk 51 and the second driving disk 52 are matched, the transport rollers 2 carry the cloth for transportation; a tensile detection component 6 is provided in the detection box 1, and the tensile detection component 6 includes a pair of rotating disks 6 1, a pair of pulling rollers 62 are fixedly connected to the side ends of a pair of rotating disks 61, and an intermittent driving component 7 is provided on the rotating disk 61. The intermittent driving component 7 is used to intermittently drive the pulling roller 62 to rotate to pull the cloth; the rotating disk 61 is also provided with a disconnecting component 8, and the disconnecting component 8 includes an air delivery box 81, and an air delivery pipe 82 is fixedly connected to the side end of the air delivery box 81. The end of the air delivery pipe 82 is slidably connected to a push rod 83, and the push rod 83 is used to intermittently drive the first driving disk 51 to separate from the second driving disk 52, forcing the transport roller 2 to stop following the rotation of the first driving disk 51.

[0038] In the present embodiment, two pairs of transport rollers 2 are provided, and the two pairs of transport rollers 2 clamp the cloth in an overtight state, so that during the process of the upper and lower pairs of transport rollers 2 rotating in opposite directions, the cloth can be transported under the combined action of the clamping force and the friction force, and when the transport rollers 2 stop rotating, the cloth is tightly clamped by the clamping rollers. Initially, when the first driving disk 51 and the second driving disk 52 are engaged, the transport rollers 2 carry the cloth for transportation. After a period of time, the rotating disk 61 starts to rotate, and during the initial rotation, it will move with the second driving disk 52, so that the transport rollers 2 stop rotating with the first driving disk 51. Since the transport rollers 2 clamp the cloth at this time, when the pulling roller 62 continues to rotate, it will pull this section of cloth to detect the elasticity and tensile resistance of the cloth, and subsequently the following cloth will be automatically transported, and the tensile resistance of the cloth will be tested section by section, thereby achieving the purpose of automatic tensile resistance testing of the entire roll of cloth and improving the efficiency of cloth testing.

[0039] See also Figure 3In an embodiment further provided by the present invention, the transmission component 5 also includes a transmission box 53 fixedly connected to the outer end of the detection box 1, a reduction motor 54 is fixedly connected to the inner top surface of the transmission box 53, a driving shaft 55 is fixedly connected to the output end of the reduction motor 54, a first bevel gear 56 is fixedly sleeved on the outer end of the driving shaft 55, an inner rotating shaft 57 is rotatably connected to the outer wall of the transmission box 53, the inner rotating shaft 57 is slidably connected to the inside of the first rotating shaft 3, a second bevel gear 58 is fixedly sleeved on the outer end of the inner rotating shaft 57, the first bevel gear 56 is meshed with the second bevel gear 58, and a first movable hole is opened on the detection box 1 The first rotating shaft 3 moves inside the first movable hole, a transmission rod 59 is provided at the side end of the first driving disk 51, and a transmission hole 510 is opened at the side end of the second driving disk 52. The transmission rod 59 initially extends into the transmission hole 510; the transmission rod 59 includes an outer rod 591 and an inner rod 592 slidably connected to the inner wall of the outer rod 591, and elastic cotton is fixedly connected between the bottom of the inner rod 592 and the inner bottom of the outer rod 591. By providing the elastic cotton, when the inner rod 592 is not aligned with the transmission hole 510, the inner rod 592 can be put into a contracted state first until the inner rod 592 enters the transmission hole 510.

[0040] Specifically, a pair of first rotating shafts 3 close to each other have transmission gears fixedly sleeved on their outer ends, which mesh with each other so that the upper and lower pairs of transport rollers 2 rotate in opposite directions. The other pair of transport rollers 2 can rotate synchronously with the transport rollers 2 at the same height through a conveyor belt.

[0041] The reduction motor 54 is turned on, and the reduction motor 54 rotates with the first bevel gear 56. Through the meshing between the first bevel gear 56 and the second bevel gear 58 (in this embodiment, the number of teeth of the first bevel gear 56 can be half the number of teeth of the second bevel gear 58), the inner shaft 57 is driven by the second bevel gear 58 to rotate. In the initial stage, the inner rod 592 enters the transmission hole 510, and the first drive disk 51 and the second drive disk 52 are in a synchronous motion state, so that the first shaft 3 rotates with the transport roller 2. At the same time, due to the meshing of a pair of transmission gears, the upper and lower pairs of transport rollers 2 are finally rotated in opposite directions, which is convenient for transporting cloth.

[0042] See also Figure 5 , Figure 8 In an embodiment further provided by the present invention, the tensile testing component 6 also includes a plurality of support rods 63 fixedly connected to the side end of one of the rotating disks 61, an annular groove 64 is provided on the inner wall of the testing box 1, the support rods 63 rotate on the inner wall of the annular groove 64, a reset rod 65 is fixedly connected to the side end of the other rotating disk 61, the outer end of the reset rod 65 is fixedly sleeved with a first spring roll 66, and the other end of the first spring roll 66 is fixedly connected to the inner wall of the testing box 1.

[0043] The purpose of supporting a pair of rotating disks 61 can be achieved through multiple support rods 63 and reset rods 65. There is a pair of pulling rollers 62 between the rotating disks 61. The cloth passes through the middle of the pair of pulling rollers 62. When the pulling rollers 62 start to rotate, the cloth can be pulled.

[0044] See also Figure 4 In the solution further provided by the present invention, an intermittent rotating component is arranged inside the transmission box 53, and the intermittent rotating component includes an intermittent rotating shaft 71 and a driven shaft 72 which are rotatably connected to the inner wall of the transmission box 53. The outer end of the intermittent rotating shaft 71 is fixedly sleeved with a first reduction gear 73, and the outer end of the inner rotating shaft 57 is fixedly sleeved with a second reduction gear 74. The gear ratio of the first reduction gear 73 to the second reduction gear 74 can be 1:6. The first reduction gear 73 is meshed with the second reduction gear 74, and the intermittent rotating shaft 71 is fixedly sleeved with a first reduction gear 73. The outer ends of the shaft 71 are fixedly sleeved with a stop disk 75 and a driving disk 76, respectively; the outer end of the driven shaft 72 is fixedly sleeved with a driven disk 77; the driving disk 76 is fixedly connected with a lever 78; the stop disk 75 is provided with a movable groove 79; the driven disk 77 is provided with a plurality of drive grooves 710 and arc grooves 711; the plurality of drive grooves 710 and arc grooves 711 are distributed in an interval ring shape; a limited-time drive component 9 is provided on the driven shaft 72; the limited-time drive component 9 is used to drive the rotating disk 61 to rotate within a set time.

[0045] See also Figure 6 The time-limited driving component 9 includes a transmission shaft 91 that rotates on the inner wall of the detection box 1. The outer ends of the transmission shaft 91 and the driven shaft 72 are fixedly sleeved with pulleys 92. The outer ends of a pair of pulleys 92 are provided with a transmission belt 93. The transmission belt 93 is connected to the pair of pulleys 92 for transmission. The outer end of the transmission shaft 91 is fixedly connected with a paddle 94. A guide groove 95 is provided on the rotating disk 61. The inner wall of the guide groove 95 is slidably connected with a driven block 96. The driven block 96 is made of iron. A magnetic block is embedded and connected to the inner wall of the guide groove 95 near the driven block 96. The magnetic force between the magnetic block and the driven block 96 is greater than the elastic force of the first spring coil 66. A first elastic member 97 is fixedly connected between the outer end of the driven block 96 and the inner wall of the guide groove 95. The first elastic member 97 is an arc spring.

[0046] When the reduction motor 54 is started, the intermittent shaft 71 can be rotated by the first reduction gear 73 and the second reduction gear 74, and the intermittent shaft 71 can rotate with the active disk 76. Since there is a gear ratio between the first reduction gear 73 and the second reduction gear 74, when the first shaft 3 rotates a set number of circles (according to the gear ratio set above, here it is 6), the active disk 76 rotates one circle and rotates the driven disk 77 90 degrees through the lever 78. The lever 78 first enters the driving groove 710 and rotates the driven disk 77 90 degrees. Then, the stop disk 75 fits with the arc groove 711 to brake the driven disk 77 so that the driven disk 77 only rotates 90 degrees each time. By setting the transmission belt 93 and the pulley 92 , and can also drive the transmission shaft 91 and the rotating disk 61 to rotate 90 degrees. During the process of the transmission shaft 91 rotating 90 degrees, the pair of pulling rollers 62 are also rotating and pulling the cloth. At the same time, the first spring roll 66 is also winding. The paddle 94 first drives the driven block 96 to rotate nearly 90 degrees until the first spring roll 66 reaches the limit of winding and breaks through the magnetic force of the magnetic block and the driven block 96. The driven block 96 will slide in the guide groove 95 until it slides from the inner circle to the outer circle, breaking away from the interference of the paddle 94, so that the rotating disk 61 will return to the initial position under the action of the first spring roll 66, that is, reverse 90 degrees, and the driven block 96 also returns to the initial position under the action of the first elastic member 97 and is attracted to the magnetic block again.

[0047] See also Figure 7 In the solution further provided by the present invention, the disconnecting component 8 also includes a cam block 84 fixedly connected to the outer end of the rotating disk 61, the inner bottom of the detection box 1 is fixedly connected to the gas box 81, the inner wall of the gas box 81 is slidably connected with a sealing plate 85, and a first reset member 86 is fixedly connected between the sealing plate 85 and the gas box 81. A limiting member is arranged inside the gas pipe 82 near the push rod 83, and a pressure limiting valve is arranged inside the gas pipe 82. When the push rod 83 moves to the farthest point, the position will be limited by the internal limiting member, and the excess gas will go out through the pressure limiting valve.

[0048] Initially, the cam block 84 contacts the sealing plate 85. When the cam block 84 starts to rotate following the rotating disk 61, it presses the sealing plate 85 first (note: at this time, there is still a distance between the paddle 94 and the driven block 96). Before the paddle 94 reaches the driven block 96, the air pipe 82 has already delivered gas to move the push rod 83 and push the second driving disk 52 away, so that the transport roller 2 stops rotating first, and then triggers the pulling roller 62 to rotate to pull the cloth. Example

[0049] See also Figure 8-Figure 9The difference between the second embodiment and the first embodiment is that the following technical features are added: a fault self-test component 10 is arranged on the outside of the first rotating shaft 3, and the fault self-test component 10 includes a rotating drum 101 rotatably connected to the detection box 1, and the outer end of the rotating drum 101 is also provided with a second spring roll 102, and the outer end of the first rotating shaft 3 is fixedly connected with a plurality of first push rods 103, and the inner wall of the rotating drum 101 is fixedly connected with a second push rod 104, and the outer end of the second rotating shaft 4 is slidably connected with a reset cylinder 105, and the inner wall of the reset cylinder 105 is slidably connected with a reset plate 106, and a second reset member 107 is arranged between the reset plate 106 and the inner wall of the reset cylinder 105, and the second reset member 107 is a reset spring.

[0050] When the push rod 83 pushes the second driving disk 52 open, the first rotating shaft 3, the transport roller 2 and the second rotating shaft 4 below are moved together, and a push plate is arranged between the upper and lower pairs of first rotating shafts 3, and a pair of axial holes are opened on the push plate. The first rotating shaft 3 rotates inside the axial holes, and a pair of push rings are fixedly sleeved on the first rotating shaft 3. The push ring arranged near the lower first rotating shaft 3 is located on one side of the push plate, and the push ring arranged near the upper first rotating shaft 3 is located on the other side of the push plate. Therefore, when the first rotating shaft 3 located at the bottom is pushed, the first rotating shaft 3 located at the top can also be pushed at the same time, and the second reset member 107 can be pressed through the second rotating shaft 4. At this time, the first push rod 103 is located between the pair of second push rods 104.

[0051] When the push rod 83 returns to the initial position under the action of air pressure, the transport roller 2, the first rotating shaft 3 and the second rotating shaft 4 return to the initial position under the elastic force of the second reset member 107, so that the first driving disk 51 and the second driving disk 52 fit together again, and the transport roller 2 can be transported again.

[0052] See also Figure 9-11In the solution further provided by the present invention, a stopping transport component 11 is further provided on the disconnecting component 8, and the stopping transport component 11 includes a traction rope 111 fixedly wound around the outer wall of the rotating drum 101, and the end of the traction rope 111 is fixedly connected to a first inclined block 112, and the first inclined block 112 is slidably connected to the outer wall of the gas transmission box 81. A limiting groove is provided at the side end of the gas transmission box 81, and a baffle 113 is slidably connected in the limiting groove. A second inclined block 114 is fixedly connected to the bottom of the baffle 113, and a second elastic member 115 is fixedly connected to the end of the baffle 113. The second elastic member 115 is a telescopic plate, and the telescopic plate is slidably connected to the baffle 113. A compression spring is arranged inside the baffle 113, one end of the compression spring is connected to the telescopic plate, the end of the second elastic member 115 is fixedly connected to an arc plate 116, the arc surface of the arc plate 116 faces downward, the top of the sealing plate 85 is slidably connected to an inclined plate 117, the arc surface faces upward, a pair of guide grooves 118 are opened on the inner wall of the gas transmission box 81, and a telescopic rod 119 is fixedly connected to the end of the inclined plate 117, the telescopic rod 119 has an elastic reset part, and the end of the telescopic rod 119 is fixedly connected to a limiting block 1110, and the limiting block 1110 is also made of iron, and a magnetic sheet is embedded in the inner wall of the guide groove 118 near the bottom.

[0053] When the sealing plate 85 descends, the rotating drum 101 will also rotate at the same time and pull the first inclined block 112 through the traction rope 111. The first inclined block 112 will push the second inclined block 114 to move, pulling the baffle 113 and the telescopic plate to move, and then the sealing plate 85 smoothly descends to the lowest point. At the same time, the limit block 1110 also descends to the lowest point and is attracted by the magnetic sheet, so that the telescopic rod 119 is extended, so that the limit block 1110 smoothly enters the guide groove 118, and then the sealing plate 85 starts to rise, and the rotating drum 101 is also reset, so that the baffle 113 and the telescopic plate also return to the initial position. Due to the fixation of the limit block 1110 by the guide groove 118, the inclined panel 117 moves upward and pushes open the arc plate 116. The arc plate 116 shrinks with the telescopic plate, and the sealing plate 85 moves smoothly to the highest point.

[0054] When there is a quality problem with the cloth, the cloth is pulled and broken by the pulling roller 62, and the friction of the cloth is lost. The drum 101 is reset in advance under the action of the first spring coil 66, so that the arc plate 116 pushes away the inclined plate 117. After the inclined plate 117 leaves the initial position, the sealing plate 85 drops to the lowest point again, and the limit block 1110 cannot attract the magnetic sheet, so that the sealing plate 85 is in contact with the arc plate 116. The sealing plate 85 will directly contact the telescopic plate, resulting in the inability to push the arc plate 116 to shrink. The sealing plate 85 finally stops at the baffle 113 position, that is, at this time, the gas in the gas pipe 82 will no longer return to the inside of the gas box 81, and the push rod 83 will always be at a certain distance from the transmission hole 510, resulting in the first drive disk 51 being unable to fit with the second drive disk 52, the transport roller 2 stops rotating, and the machine stops running. The staff observes that the cloth is no longer unrolled, and they already know that there is a quality problem with the cloth and need to check or replace the cloth in time.
