Description

Technical Field

[0001] The invention relates to the field of slitting equipment, in particular to a synchronous driving structure for single-blade double-rotation full-synchronous slitting equipment. Background Art

[0002] Single blade double rotary full synchronous slitting equipment is a kind of equipment used to cut continuous materials (such as paper, plastic film, metal foil, etc.) into specific widths.

[0003] At present, the single-blade double-rotation fully synchronous slitting equipment includes a paper feeding system, a slitting system, a paper conveying system, etc. The paper feeding system ensures that the paper enters the slitting system smoothly, and is equipped with a tension control detection system. At the same time, the roll diameter detection system will control the anti-curling and flattening device to press down according to the size of the paper roll diameter, thereby achieving the flattening effect on the paper. The slitting system includes a longitudinal slitting system and a transverse slitting system. Among them, the longitudinal slitting system is initially set according to the paper width requirements, and the slitting knife structure controlled by a servo motor can realize automatic knife arrangement. The transverse slitting system adopts the method of synchronous reverse tangency of the upper and lower rotary knife rollers to realize the transverse cutting function of the paper length at different vehicle speeds, speed-up process, and speed-down process. The paper conveying system is divided into a high-speed conveying part and a low-speed conveying part. The high-speed conveying part allows the paper to quickly leave the transverse cutting area after transverse slitting, and the low-speed conveying part realizes the purpose of paper stacking, while reducing the paper conveying speed, providing a reasonable working condition for the paper sorting system. This system ensures that the paper conveying process is not messy, stable, and has no speed difference, avoiding wear marks. The high conveyor belt part is composed of one section of high-speed conveyor belt and two sections of high-speed conveyor belt. A waste paper door mechanism is arranged between the two sections of high-speed belt to automatically discharge waste paper for unqualified paper.

[0004] In terms of synchronous drive, the chain drive or ordinary gear drive used in some early slitting equipment also had obvious defects. Since the chain drive structure itself has a certain degree of elasticity and relaxation, it is easy for the chain to be elongated and jump teeth during long-term operation. This will not only destroy the synchronization between the double rotating knife shafts, resulting in a decrease in slitting accuracy, but also frequently cause equipment failures, requiring a lot of manpower and time for maintenance and adjustment. Although ordinary gear transmission is relatively stable, after high-speed operation or long-term use, the gears are prone to wear and the tooth side clearance gradually increases, which will also affect the synchronization accuracy of the double rotating knife shafts, making the quality of the products after slitting uneven and unable to meet the needs of high-precision production. Summary of the invention

DETAILED DESCRIPTION

[0037] 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.

[0038] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0039] Example 1

[0040] like Figure 1 , Figure 2 , Fig.15 As shown, in order to reduce the probability of synchronous cutting errors caused by problems in the transmission mode, this embodiment provides a new method for attaching Fig.15 The driving mechanism of the slitting device shown in the figure cooperates with the paper feeding system and the paper conveying system of the slitting device to complete the slitting process of paper and other products. The driving mechanism realizes the power transmission connection between the motor 1, the first slitting roller 2, and the second slitting roller 3, providing support for the cross-cutting and longitudinal-cutting process of paper and other products.

[0041] As Figure 1 , Fig.11 , Fig.13 shown, in order to be able to cross-cut the product through the first slitting roller 2, a slitting knife 21 is provided in the notch of the first slitting roller 2, and the slitting knife 21 is arranged perpendicular to the product traveling direction. In order to achieve the longitudinal cutting of the product, slitting discs 32 are sleeved on both ends of the second slitting roller 3.

[0042] As Figure 4 , Figure 6 , Fig.11 shown, in order to stably install the first slitting roller 2 and the second slitting roller 3, brackets 5 need to be provided at the ends of the first slitting roller 2 and the second slitting roller 3, and the brackets 5 are installed on the frame of the slitting equipment. Specifically, the bracket 5 is set as a U-shaped structure with an upward opening, and strip holes are provided on the side walls. At the same time, a first support plate 51 and a second support plate 52 are provided inside the bracket 5. The ends of the first support plate 51 and the second support plate 52 both penetrate through the strip holes of the bracket 5, and a top plate 53 is provided at the top of the strip holes. Among them, the first support plate 51 is connected to the bracket 5 through bolts. Therefore, the position of the first support plate 51 can be adjusted by adjusting the position of the bolts penetrating the bracket 5. The second support plate 52 is arranged above the first support plate 51, and a first adjusting screw 54 protrudes through the end of the bracket 5 and is inserted into the first support plate 51 through a bearing connection at the end. Therefore, when the first adjusting screw 54 is rotated, the second support plate 52 can be controlled to rise and fall, providing support for adjusting the relative position of the slitting rollers arranged vertically.

[0043] As Figure 4 , Figure 5 shown, in order to install the first slitting roller 2 and the second slitting roller 3 on their respective brackets 5 without affecting the rotation of the slitting rollers, first bearing seats 22 are sleeved on both ends of the first slitting roller 2 and the second slitting roller 3. The first bearing seat 22 of the second slitting roller 3 is installed on the second support plate 52. Since there are two first slitting rollers 2 arranged parallel up and down, the first bearing seats 22 of the two first slitting rollers 2 are respectively installed on the first support plate 51 and the second support plate 52.

[0044] As Figure 4 , Figure 7As shown, in order to be able to control the synchronous rotation of the two first slitting rollers 2, a wheel group 6 is arranged at the ends of the two first slitting rollers 2, and the wheel group 6 includes a first wheel body 61, a second wheel body 62, a third wheel body 63 and a fourth wheel body 64. The first wheel body 61 and the second wheel body 62 have the same diameter and are respectively arranged at the ends of the two first slitting rollers 2. The third wheel body 63 and the fourth wheel body 64 are respectively arranged on both sides of the first slitting roller 2, and are connected to the first wheel body 61 and the second wheel body 62 through a first belt 65. At the same time, the third wheel body 63 and the fourth wheel body 64 are installed on the bracket 5. Therefore, under the action of the first belt 65, the first wheel body 61 and the second wheel body 62 can be controlled to rotate in opposite directions, thereby controlling the two first slitting rollers 2 to rotate in opposite directions.

[0045] In order to ensure the synchronous rotation of the first wheel body 61 and the second wheel body 62, the belt is set as a synchronous belt, and the wheel body is set as a synchronous pulley. The structural characteristics of the synchronous belt and the synchronous pulley are used to achieve the synchronous rotation of the first wheel body 61 and the second wheel body 62. In addition, the fourth wheel body 64 is set to an adjustable state, and the tension of the belt can be adjusted by adjusting the position of the fourth wheel body 64.

[0046] like Fig. 9 As shown, specifically, the end of the central axis of the fourth wheel body 64 is sleeved with a second bearing seat 66, a support rod 67 is penetrated at one end of the second bearing seat 66, and a second adjusting screw 68 is threadedly penetrated at the other end, and the support rod 67 and the second adjusting screw 68 are fixedly mounted on a fixing plate 69, and the fixing plate 69 is connected to the bracket 5 by bolts. With the cooperation of the support rod 67, the second adjusting screw 68 and the fixing plate 69, the fourth wheel body 64 can be stably mounted on the bracket 5, and the position of the fourth wheel body 64 can be adjusted by rotating the second adjusting screw 68 to adjust the belt tension.

[0047] like Figure 7 , Figure 8 As shown, in order to further reduce the probability of slipping of the belt and the wheel body, a second adjusting mechanism 7 is provided on the side of the first wheel body 61 and the second wheel body 62. The second adjusting mechanism 7 includes a pressure wheel 75. The pressure wheel 75 is provided on the side of the first wheel body 61 and the second wheel body 62, and cooperates with the first wheel body 61 and the second wheel body 62 to squeeze the belt, increase the pressure between the belt and the first wheel body 61 and the second wheel body 62, and increase the friction.

[0048] like Figure 8As shown, in order to control the stable installation of the pressing wheel 75, the pressing wheel 75 is installed on the frame 74, and a stud 71 is provided at the end of the frame 74 through a bearing connection, and a limiting rod 73 is fixedly installed, the limiting rod 73 is arranged through the support plate 72, and the stud 71 is threadedly arranged through the support plate 72, and the support plate 72 is connected to the bracket 5 through a bolt. With the cooperation of the support plate 72, the limiting rod 73, and the stud 71, the stable installation of the pressing wheel 75 is achieved, and the position of the pressing wheel 75 can be adjusted by rotating the stud 71, which provides convenience for pressing the belt.

[0049] like Figure 1 As shown, when the slitting roller is stably installed, in order to control the rotation of the slitting roller, a motor 1 is arranged on the side of the bracket 5, and the first driving wheel of the output shaft of the motor 1 is connected to the first driven wheel 24 of a first slitting roller 2 through the second belt, and the second driving wheel is connected to the second driven wheel of the second slitting roller 3 through the third belt. The diameter of the first driving wheel is smaller than the diameter of the second driving wheel. Under the same angular velocity, the smaller the diameter, the smaller the speed. Therefore, the speed of the second belt is smaller than the speed of the third belt. And the diameter of the first driven wheel 24 is larger than the first driving wheel, and the diameter of the second driven wheel is smaller than the diameter of the second driving wheel. Under the same belt speed, the smaller the diameter, the greater the angular velocity. Therefore, the angular velocity of the first driven wheel 24 is smaller than the angular velocity of the first driving wheel, and the angular velocity of the second driven wheel is greater than the angular velocity of the second driving wheel. Therefore, the angular velocity of the first driven wheel 24 is smaller than the angular velocity of the second driven wheel, which means that the angular velocity of the first slitting roller 2 is smaller than the angle of the second slitting roller 3, providing support for the first slitting roller 2 and the second slitting roller 3 to cooperate to achieve cross-cutting and longitudinal cutting of the product. In addition, in order to avoid damaging the product, the rotation speed of the slitting disc 32 needs to be adapted to the traveling speed of the product.

[0050] like Figure 3As shown, in order to adjust the tension of the second belt and the third belt and provide support for synchronous rotation, a bottom plate 11 and a bottom frame 13 are provided at the bottom of the motor 1, and the bottom frame 13 is provided below the bottom plate 11. A threaded column 12 is provided at the end corner below the bottom plate 11 through a bearing connection, and a first sprocket 15 is provided on the threaded column 12. Multiple first sprockets 15 are connected by a chain, and a polygonal column is provided on a certain threaded column 12. Therefore, the staff can use a wrench and a polygonal column to control the rotation of a certain threaded column 12, thereby driving multiple threaded columns 12 to rotate. An internal threaded tube 14 is fixedly provided at the end corner above the bottom frame 13, and the bottom thread of the threaded column 12 is inserted into the internal threaded tube 14. Therefore, when the threaded column 12 rotates, the relative position of the bottom plate 11 and the bottom frame 13 can be adjusted. Therefore, after the bottom frame 13 is stably installed on the frame of the slitting equipment, the position of the motor 1 can be adjusted by adjusting the position of the bottom plate 11, thereby adjusting the tension of the belt. The belt can also be set as a synchronous belt, and the wheel body can be set as a synchronous pulley, and the structural characteristics of the synchronous belt and the synchronous pulley can be used to achieve synchronous rotation.

[0051] like Figure 1 , Fig.10 As shown, in addition, a first adjustment mechanism 4 can be set on the side of the second belt and the third belt, and the belt tension can be adjusted by the first adjustment mechanism 4. Specifically, the first adjustment mechanism 4 includes an intermediate plate 42, a bidirectional screw 44 and two limiting wheels 45. The intermediate plate 42 is installed on the bracket 5 through a connecting plate 41, and a buckle groove 43 is set on the side wall, and the end of the buckle groove 43 is set to be an opening. The two limiting wheels 45 are distributed at both ends of the intermediate plate 42, and the end of the central axis protruding the limiting wheel 45 is installed with a buckle plate 46, and the buckle plate 46 extends into the buckle groove 43, so as to realize the stable connection between the limiting wheel 45 and the intermediate plate 42, and provide convenience for adjusting the relative position of the limiting wheel 45 and the intermediate plate 42 according to needs. The bidirectional screw 44 is installed on the side of the intermediate plate 42, and the end thread penetrates the buckle plate 46, and the position of the limiting wheel 45 can be adjusted by rotating the bidirectional screw 44. Because the limiting wheel 45 is in contact with the belt, the tension of the belt can be adjusted when its position is adjusted. According to actual needs, the second adjustment mechanism 7 can be installed on the sides of the driving wheel and the driven wheel to increase the pressure between them and the belt.

[0052] like Figure 2 , Fig.14As shown, in order to monitor the rotation speed of the slitting roller, a speed measuring component 9 is provided at the end of the first slitting roller 2 and the second slitting roller 3, and the speed measuring component 9 can monitor the rotation speed of the slitting roller in real time. Specifically, the speed measuring component 9 includes a ring plate 91 and a Hall speed sensor 95. The ring plate 91 is sleeved on the end of the slitting roller, and a side plate 94 is fixedly provided at the end, and a polygonal tube 93 is fixedly provided in the middle of the side plate 94. The polygonal tube 93 is connected by bolts and inserted into the polygonal groove 23 of the slitting roller, so that the ring plate 91 and the slitting roller keep rotating synchronously. A magnet 92 is embedded in the inner wall of the ring plate 91, and the Hall speed sensor 95 is provided on the side of the ring plate 91 and is installed on the bracket 5 through an L-shaped plate 96. When an object with a magnetic field approaches or passes through the Hall element, the Hall element will generate a Hall potential, which is related to the magnetic field strength and the moving speed of the object. That is, when a rotating metal part passes through the magnetic field of the Hall sensor, it will cause a potential change, and the rotation speed value of the measured object can be obtained by measuring the potential.

[0053] In order to receive information from the Hall speed sensor 95, the Hall speed sensor 95 needs to be connected to a host computer (such as an industrial computer, controller, etc.), and its connection method has been disclosed. For example, the Hall speed sensor 95 is connected to the host computer via serial communication.

[0054] Example 2

[0055] like Fig.13 As shown, on the basis of Example 1, in order to be able to adjust the position of the slitting disc 32 according to needs and adapt to different slitting needs, a clamping groove 31 is provided on the second slitting roller 3, and the clamping groove 31 is arranged along the length direction of the second slitting roller 3, and the end is arranged to be open. A clamping column 34 is fixedly arranged on the inner side wall of the slitting disc 32, and a limiting bolt is threadedly penetrated on the convex plate 33 fixed on the side. The slitting disc 32 is sleeved on the second slitting roller 3, and the clamping column 34 is located in the clamping groove 31. The end of the limiting bolt is pressed against the second slitting roller 3, so that the slitting disc 32 and the second slitting roller 3 can rotate synchronously, which provides convenience for adjusting the position of the slitting disc 32 relative to the second slitting roller 3.

[0056] like Fig.11 , Fig.12As shown, in order to more accurately adjust the position of the slitting disc 32, a measuring mechanism 8 is provided at both ends of the side of the second slitting roller 3. The measuring mechanism 8 includes a frame 82, a sleeve 84 and a straight plate 87. The frame 82 is installed on the support plate, and a push rod 81 is provided on the top. The sleeve 84 can be lifted and lowered at the bottom of the frame 82. The lower end of the push rod 81 is threadedly inserted into the sleeve 84, and a spring 83 is sleeved. The sleeve 84 is in a compressed state. The top of the spring 83 contacts the top of the frame 82, and the bottom contacts the sleeve 84. Under the action of the spring 83, the sleeve 84 has a tendency to fit the support plate, and it is convenient to control the rise of the sleeve 84. The straight plate 87 is arranged through the sleeve 84, and the end of the limit bolt 85 threaded through the sleeve 84 is pressed against the straight plate 87, so that the straight plate 87 and the sleeve 84 are adjustable. Therefore, the position of the straight plate 87 relative to the sleeve 84 can be adjusted according to the adjustment of the position of the slitting disk 32. A scale 86 is provided on the upper side of the straight plate 87, and an arc groove 88 is provided at the arc end. The edge of the slitting disk 32 can extend into the arc groove 88, thereby realizing a more accurate adjustment of the position of the slitting disk 32.

[0057] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0058] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
