[0038] The following is a further detailed description of the embodiments of the present disclosure in conjunction with the accompanying drawings and examples. The detailed description of the following embodiments and the accompanying drawings are used to exemplarily illustrate the principles of the present disclosure, but cannot be used to limit the scope of the present disclosure. The present disclosure can be implemented in many different forms and is not limited to the specific embodiments disclosed herein, but includes all technical solutions that fall within the scope of the claims.

[0039] See also Figure 1-Figure 11 , a diaphragm cutting and sampling device, comprising:

[0040] A cross-cutting mechanism 1, used for cutting the diaphragm horizontally for sampling;

[0041] Thickness detector 2, used for measuring the thickness of the diaphragm;

[0042] The longitudinal cutting mechanism 3 is used to cut the diaphragm longitudinally to complete the sampling;

[0043] The cross-cutting mechanism 1 comprises a cross-cutting base 11 on which a cross-cutting knife 17 is arranged. The cross-cutting base 11 is provided with a stepping mechanism 5 for intermittent displacement of the diaphragm, so as to facilitate stable and continuous thickness detection of the diaphragm.

[0044] An adjustment mechanism 6 is provided between the cross-cutting base 11 and the cross-cutting knife 17 so that the position of the cross-cutting knife 17 can be adjusted during the membrane conveying process, thereby adapting to the sampling of membranes of different widths.

[0045] See also Figure 2-Figure 4 A plurality of rotating rods 12 are rotatably mounted on the cross-cutting base 11, and a transmission belt 13 is installed between the plurality of rotating rods 12, and all the rotating rods 12 are rotated synchronously through the transmission belt 13. A limit rod 14 is fixedly mounted on one end of the rotating rod 12, and a film pressing roller 15 is slidably mounted on the limit rod 14. The limit rod 14 is a petal-shaped structure, and the film pressing roller 15 and the limit rod 14 are adapted to each other, so that the limit rod 14 can drive the film pressing roller 15 to rotate synchronously, and the rotation of the film pressing roller 15 plays the role of conveying the diaphragm. Fixed rollers 16 are fixedly mounted on the limit rod 14 at both ends, which are used to fixedly convey the two sides of the diaphragm, so that the diaphragm is more stable during transportation.

[0046] There are two crosscut knives 17, which can cut both sides of the diaphragm so that the width of the diaphragm meets the standard of the test sample. A crosscut groove 18 is opened on the crosscut base 11, and the crosscut knife 17 is located inside the crosscut groove 18, so that the crosscut knife 17 is more stable when cutting the diaphragm, and the diaphragm will be completely cut without incomplete cutting.

[0047] See also Figure 5-Figure 6 The longitudinal cutting mechanism 3 includes a longitudinal cutting base 31, on which a plurality of pressure rollers 32 are rotatably mounted, and a transmission belt 33 is installed between the plurality of pressure rollers 32, and the transmission belt 33 enables the plurality of pressure rollers 32 to move synchronously.

[0048] The distance between the pressure roller 32 and the longitudinal cutting base 31 is consistent with the distance between the film pressing roller 15 and the transverse cutting base 11, and both play a role in conveying the diaphragm. The film pressing roller 15 conveys the two sides of the diaphragm, and the pressure roller 32 directly conveys the cut diaphragm as a whole.

[0049] A storage groove 38 is provided on the longitudinal cutting base 31, and a push rod 39 is connected to the storage groove 38 through a spring. The push rod 39 can lift the diaphragm, thereby extending the transmission path of the diaphragm, playing a protective role, avoiding the diaphragm from breaking due to different speeds and jamming when the diaphragm is transported on the transverse cutting base 11 and the longitudinal cutting base 31, so that the diaphragm has a certain buffer distance, so that the diaphragm will not be broken or wrinkled.

[0050] A longitudinal cutting seat 34 is fixedly mounted on the longitudinal cutting seat 31, a cylinder 36 is fixedly mounted on the longitudinal cutting seat 34, a longitudinal cutting knife 35 is fixedly mounted on the bottom of the cylinder 36, and the cylinder 36 can drive the longitudinal cutting knife 35 to move up and down, so as to cut the diaphragm. Since the diaphragm is in a uniform motion state on the longitudinal cutting seat 31, the cutting spacing of the longitudinal cutting knife 35 is changed by controlling the lifting speed of the cylinder 36, thereby changing the longitudinal cutting distance of the diaphragm, and finally changing the size of the sample. A longitudinal cutting groove 37 is provided on the longitudinal cutting seat 31, and the longitudinal cutting groove 37 and the longitudinal cutting knife 35 are adapted to each other, so that the longitudinal cutting knife 35 can completely cut the diaphragm during cutting, avoiding the phenomenon that the diaphragm is not cut when the longitudinal cutting knife 35 is cutting.

[0051] See also Figure 2-Figure 11The adjusting mechanism 6 includes an adjusting roller 61, which is rotatably mounted on the limiting rod 14. The inside of the adjusting roller 61 is a smooth structure, so that the adjusting roller 61 can move along the limiting rod 14 without affecting the rotation of the limiting rod 14. The adjusting roller 61 is rotatably connected to the film pressing roller 15, so that the film pressing roller 15 can move synchronously with the adjusting roller 61, and the adjusting roller 61 will not affect the rotation of the film pressing roller 15. Multiple adjusting rollers 61 are connected by a connecting rod 62, so that the multiple adjusting rollers 61 are connected into a whole, which plays a limiting role, so that the adjusting roller 61 will not rotate with the limiting rod 14.

[0052] See also Figure 10-11 Two mounting seats 65 are fixedly installed on the cross-cutting base 11, and an adjusting rod 66 is rotatably installed between the two mounting seats 65. One end of the adjusting rod 66 is fixedly connected to a motor for driving the adjusting rod 66 to rotate. An adjusting cone tooth 1 67 is slidably installed on the adjusting rod 66. Preferably, the adjusting rod 66 can be a petal-shaped structure, and the adjusting cone tooth 1 67 is adapted to the adjusting rod 66, so that the adjusting cone tooth 1 67 can be displaced along the adjusting rod 66 or rotated with the adjusting rod 66. The adjusting rod 66 can also be a non-circular structure such as a triangle or a rectangle, so that the adjusting rod 66 can play a role in limiting the rotation of the adjusting cone tooth 1 67, and the adjusting cone tooth 1 67 can slide along the adjusting rod 66.

[0053] The first adjusting bevel gear 67 is meshedly connected with the second adjusting bevel gear 68, and the bottom end of the second adjusting bevel gear 68 is fixedly installed with an adjusting screw rod 69, and the adjusting screw rod 69 is threadedly connected with the cross-cutting knife 17, and the adjusting frame 64 is fixedly installed on the adjusting roller 61. The adjusting frame 64 is slidably connected with the cross-cutting knife 17, and is rotatably connected with the adjusting screw rod 69. The rotation of the first adjusting bevel gear 67 can drive the second adjusting bevel gear 68 to rotate, and the rotation of the second adjusting bevel gear 68 drives the adjusting screw rod 69 to rotate, and the rotation of the adjusting screw rod 69 drives the cross-cutting knife 17 to move up and down along the adjusting frame 64.

[0054] The adjusting rollers 61 are fixedly connected by a connecting rod 62, and a bidirectional screw rod 63 is threaded on the connecting rod 62. The connecting rod 62 can be driven to move by rotating the bidirectional screw rod 63. The connecting rod 62 drives the adjusting roller 61, the film pressing roller 15, and the adjusting frame 64 to move toward or relative to each other, thereby causing the two cross-cutting knives 17 to move toward or relative to each other, thereby adjusting the cross-cutting width of the diaphragm.

[0055] The two ends of the adjusting roller 61 are respectively a film pressing roller 15 and a fixed roller 16, so that the membrane is more stable when being transported, and the membrane will not shake when being cut by the cross-cutting knife 17, so that the movement of the membrane during cutting is more stable. At the same time, the film pressing roller 15 is rotatably connected to the adjusting roller 61, and the fixed roller 16 is fixedly installed on the limit rod 14, so that when the adjusting roller 61 drives the film pressing roller 15 to move, the fixed roller 16 can fix the two sides of the membrane, so that the film pressing roller 15 will not drive the membrane to move, causing the membrane to wrinkle and deflect.

[0056] The two mounting seats 65 are fixedly mounted with scales 610, and the adjustment frame 64 is slidably connected to the scales 610, so that the spacing between the two crosscutting knives 17 can be visually observed. The adjustment frame 64 is in contact with the adjustment bevel gear 1 67, so that when the adjustment frame 64 is displaced, the adjustment bevel gear 1 67 can be driven to displace synchronously.

[0057] See also Figure 7-Figure 9 The stepping mechanism 5 includes a rotating seat 51, which is fixedly mounted on the cross-cutting base 11, a driving gear 52 is rotatably mounted on the rotating seat 51, a rotating seat 53 is fixedly mounted on the cross-cutting base 11, a driven rod 54 is rotatably mounted on the rotating seat 53, and a linkage gear 55 is fixedly mounted on the driven rod 54.

[0058] The driving gear 52 is meshed with the interlocking gear 55. The driving gear 52 and the interlocking gear 55 are of the same size, so that the driving gear 52 can drive the interlocking gear 55 to rotate synchronously in opposite directions, thereby driving the driven rod 54 and the pressure roller 32 to rotate in opposite directions at the same speed. A half gear 56 is also fixedly mounted on the driven rod 54. The size of the half gear 56 is larger than the interlocking gear 55, and the number of teeth on the half gear 56 is the same as the number of teeth on the interlocking gear 55. A transmission gear 57 is fixedly mounted on the rotating rod 12. The half gear 56 is meshed with the transmission gear 57. The half gear 56 can drive the transmission gear 57 to rotate, and the rotation direction is opposite to the rotation direction of the half gear 56, that is, the rotation direction of the transmission gear 57 is the same as the rotation direction of the pressure roller 32. At the same time, the transmission gear 57 is of the same size as the driving gear 52, so that the driving gear 52 can rotate intermittently, and the rotation speed is twice as fast as that of the driving gear 52.

[0059] See also Figure 1-Figure 11The pressure roller 32 is connected to the driving gear 52 through the transmission belt 34. The pressure roller 32 is equipped with a motor, which drives the pressure roller 32 to rotate. Under the transmission action of the transmission belt 2 33, all the pressure rollers 32 can be driven to rotate synchronously. At the same time, under the action of the transmission belt 34, the driving gear 52 can be driven to rotate synchronously. The driving gear 52 and the interlocking gear 55 are engaged to drive the driven rod 54 to rotate in the opposite direction, and the speed is consistent with the pressure roller 32. The driven rod 54 drives the half gear 56 to rotate, thereby driving the transmission gear 57 to rotate intermittently, and the rotation direction is opposite to that of the driven rod 54, and the rotation speed is twice faster than that of the driven rod 54. For ease of understanding, when the driven rod 54 rotates one circle, the driven rod 54 and the transmission gear 57 rotate the same distance and in the opposite direction. Thereby, the rotation direction and distance of the rotating rod 12 and the pressure roller 32 are consistent, and the pressure roller 32 rotates at a uniform speed, and the rotating rod 12 rotates intermittently, so that the diaphragm moves intermittently on the cross-cutting base 11 and moves at a uniform speed on the longitudinal cutting base 31, and within a certain time interval, the movement distance of the diaphragm on the cross-cutting base 11 and the longitudinal cutting base 31 are consistent.

[0060] The film pressing roller 15 and the pressing roller 32 are both made of insulating elastic materials, such as rubber, so that when the diaphragm is transmitted, static electricity will not be generated and a certain thickness compensation can be provided, so that the diaphragm within a certain thickness range can be adapted. The bottom end of the cross-cutting knife 17 is also a blade structure, so that the cross-cutting knife 17 can penetrate the diaphragm after being adjusted and lowered, thereby avoiding deformation of the diaphragm.

[0061] It should be noted that the present invention is a diaphragm cutting and sampling device. When in use, the diaphragm strip taken out from the film roll is placed on the cross-cutting base 11, and the bidirectional screw 63 is rotated according to the sampling requirements. The bidirectional screw 63 drives the adjustment roller 61 to move, and the adjustment roller 61 drives the adjustment frame 64 to move. The adjustment frame 64 drives the cross-cutting knife 17 to move, so that the distance between the two cross-cutting knives 17 can be adjusted. The distance between the two cross-cutting knives 17 can be determined according to the reading on the scale 610 to meet the width requirements of sampling.

[0062] The motor on the pressure roller 32 is started, and the motor can drive the pressure roller 32 to rotate. Under the transmission effect of the transmission belt 2 33, all the pressure rollers 32 can be driven to rotate synchronously. At the same time, under the effect of the transmission belt 3 4, the driving gear 52 can be driven to rotate synchronously. The driving gear 52 and the interlocking gear 55 are meshed to drive the driven rod 54 to rotate in the opposite direction, and the speed is consistent with the pressure roller 32. The driven rod 54 drives the half gear 56 to rotate, thereby driving the transmission gear 57 to rotate intermittently, and the rotation direction is opposite to that of the driven rod 54, and the rotation speed is twice faster than that of the driven rod 54. For ease of understanding, when the driven rod 54 rotates one circle, the driven rod 54 and the transmission gear 57 rotate at the same distance and in opposite directions, so that the rotation direction and distance of the rotating rod 12 and the pressure roller 32 are consistent, and the pressure roller 32 rotates at a constant speed, and the rotating rod 12 rotates intermittently, so that the diaphragm moves intermittently on the cross-cutting base 11 and moves at a constant speed on the longitudinal cutting base 31, and within a certain time interval, the movement distance of the diaphragm on the cross-cutting base 11 and on the longitudinal cutting base 31 is consistent.

[0063] The rotating rod 12 rotates synchronously under the drive of the transmission belt 13, and the rotating rod 12 drives the limiting rod 14 to rotate. Since the limiting rod 14 and the film pressing roller 15 are adapted to each other, the limiting rod 14 can drive the film pressing roller 15 to rotate, thereby achieving a conveying effect on the diaphragm. At the same time, due to the limiting effect of the connecting rod 62, the adjusting roller 61 will not rotate, and the cross-cutting knife 17 is kept stable. Driven by the film pressing roller 15, the diaphragm is displaced intermittently along the cross-cutting base 11, so that it is cut by the cross-cutting knife 17. When the cross-cutting knife 17 is cutting, the diaphragm is located on both sides of the cross-cutting knife 17 and is squeezed and limited by the film pressing roller 15 and the fixed roller 16, which can effectively avoid the phenomenon of deviation when the diaphragm is cut.

[0064] When the cross-cutting width of the diaphragm needs to be adjusted, when the diaphragm is intermittently stopped, the motor corresponding to the adjusting rod 66 is started, and the motor drives the adjusting rod 66 to rotate. Since the adjusting bevel gear 1 67 and the adjusting rod 66 are adapted, the adjusting rod 66 can drive the adjusting bevel gear 1 67 to rotate, and the adjusting bevel gear 2 68 is driven to rotate under the meshing action of the adjusting bevel gear 1 67 and the adjusting bevel gear 2 68, and the adjusting bevel gear 2 68 drives the adjusting screw rod 69 to rotate along the adjusting frame 64, and the adjusting screw rod 69 drives the cross-cutting knife 17 to move up and away from the diaphragm, and then by rotating the bidirectional screw rod 63, the spacing between the two cross-cutting knives 17 can be adjusted. When the bidirectional screw rod 63 is displaced, the film pressing roller 15 will be driven to move. Since the fixed roller 16 presses and fixes the two sides of the diaphragm, the diaphragm will not be deviated or wrinkled. The sampling width of the diaphragm is determined by determining the spacing between the two cross-cutting knives 17 through the scale 610. By utilizing the rest interval of the diaphragm, the motor is reversed to reverse the adjusting rod 66, thereby driving the cross-cutting knife 17 to move downward, penetrate the diaphragm, and re-cut the diaphragm. The sampling width of the diaphragm can be adjusted without stopping the machine or adjusting the diaphragm.

[0065] The diaphragm is transported to the thickness detector 2 through the laminating roller 15. Due to the intermittent rotation of the laminating roller 15, the diaphragm can intermittently enter the thickness detector 2, so that the thickness detector 2 can continuously and accurately detect the thickness of the diaphragm, and the detection distance is consistent each time.

[0066] After the diaphragm passes through the thickness detector 2, it is transported by the pressure roller 32, so that the diaphragm moves along the longitudinal cutting base 31. When the diaphragm passes through the push rod 39, the push rod 39 keeps the diaphragm in a taut state under the action of the spring to prevent the diaphragm from breaking. The diaphragm moves at a uniform speed along the longitudinal cutting base 31. When passing under the longitudinal cutting seat 34, the longitudinal cutting knife 35 cuts the diaphragm under the drive of the cylinder 36, so that the diaphragm is cut into samples of the size to be tested. By controlling the cutting speed of the longitudinal cutting knife 35 and coordinating the uniform running speed of the diaphragm on the longitudinal cutting base 31, samples of different sizes can be cut for testing.
