Description

Technical Field

[0001] The invention relates to the technical field of slitting machines, in particular to a slitting machine with low energy consumption and high efficiency. Background Art

[0002] A slitting machine is a device used to cut food packaging bags and other materials into suitable sizes. It uses a precise cutting device to cut continuous packaging bag materials according to set specifications to meet different packaging needs.

[0003] However, there are still some problems with the existing slitting machines: First, the tool distance needs to be adjusted during each roll change. This is because different rolls differ in width, thickness or material properties. In order to ensure the accuracy and quality of slitting, the tool distance needs to be adjusted according to the specific conditions of the new roll.

[0004] From the perspective of adjustment methods, although pneumatic adjustment has certain automation advantages, it is expensive and requires a large number of sensors, which makes the cost of this adjustment method high and requires frequent maintenance. The adjustment method combining pneumatics and sensors requires high experience from the operator. The operator must be experienced to operate well, otherwise errors are very likely to occur during operation. Moreover, during the pneumatic adjustment process, if an error occurs in the sensor, the machine needs to be shut down for maintenance. At this time, the operator needs to enter the equipment to deal with the fault. The internal space of the equipment is limited and the structure is complex. It is not only inconvenient for the operator to enter the equipment for maintenance, but the entire maintenance process is relatively long, resulting in a long period of downtime.

[0005] Taking into account the relatively small gross profit of food packaging bags, in the reality of mass production and meager profits, the existing technology usually chooses to manually adjust the knife distance. However, manual adjustment is extremely time-consuming. The operator must first roughly adjust the knives on both sides to the appropriate position, and then use measuring tools such as tape measures to accurately adjust them one by one according to the dimensions on the installation list. However, there will be errors in manual adjustment. Since this process relies on the operator's manual operation and visual judgment, different operators or the same operator in different working conditions cannot guarantee the accuracy of each adjustment. Moreover, since the knife is generally located in the middle of the equipment, the operator can only bend down to measure during the operation, which increases the physical burden on the operator. In addition, when operating in the middle of the equipment, the operator needs to be extra careful to avoid collision with other structures of the equipment, which undoubtedly increases the safety risks during the operation.

[0006] Secondly, when the slitting machine is slitting food packaging bags, waste strips will inevitably be generated. The current technology is to use a fan to generate negative pressure and suck the waste strips into a special container through a pipe for recycling and reuse.

[0007] However, there will inevitably be bends at the junction of the pipeline and the container, as well as in the setting of the pipeline itself. As a plastic material, food packaging bags have certain toughness and hardness. When the waste strips are transmitted in the pipeline under the action of negative pressure, once they reach the bend, due to their own physical properties, the waste strips will bend along the shape of the bend. This bending can easily cause the waste strips to get stuck in the bend, which in turn causes the pipeline to be blocked. Once the pipeline is blocked, the manufacturer faces two options. One is to shut down for cleaning, which will lead to production interruption. In modern industrialized production, shutdown means reduced production efficiency and inability to complete order tasks on time. For large-scale production companies, every minute of shutdown may cause huge economic losses.

[0008] Another option is to continue production and wait until the end of production for the operator to clean up the production site. However, during the production process, due to pipe blockage, the waste strips cannot be sucked into the container normally and will be scattered around the production site. Therefore, cleaning the site after production requires more manpower. Collecting the scattered waste strips is a tedious and time-consuming process.

[0009] Therefore, the present invention proposes a slitting machine with low energy consumption and high efficiency. Summary of the invention

[0022] Preferably, a threaded groove is provided on the inner wall of the suction pipe, a plurality of notched grooves are provided through the top of the suction pipe, a plurality of rotating frames are fixedly connected to the top of the suction pipe in an arc shape and arranged equidistantly, every two of the rotating frames are arranged as a group, and a curved elliptical wheel is rotatably connected between each group of rotating frames.

[0023] Preferably, the rewinding unit comprises two rewinding rollers.

[0024] Preferably, the tension roller group includes a plurality of tension rollers.

[0025] Preferably, the driving system includes three driving motors and one tension motor.

[0026] Preferably, two knife rollers rotatably connected to the outer surface of the body are arranged below the slitting knife.

[0027] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention enables the slitting knives on its surface to move away from or closer to each other through the rotation of the screw rod. During the movement of the slitting knives on the surface of the screw rod, the remaining slitting knives are driven to move synchronously with the help of the adjustment groove and the cooperation of the matching shaft. In this way, the operator does not need to inspect the slitting knives on both sides separately, which greatly improves the adjustment efficiency and reduces the error risk caused by manual operation. Due to the improvement of adjustment efficiency and the reduction of error risk, the slitting operation can be carried out more continuously and stably, reducing production interruptions or product quality fluctuations caused by improper adjustment of the slitting knife distance. At the same time, this design also improves the ease of operation of the slitting machine. The operator does not need to perform tedious double-sided inspection operations, which simplifies the operation process and reduces the workload of the operator.

[0028] Compared with the existing technology, the traditional slitting machine has many disadvantages in the tool distance adjustment. For example, the high cost and complex maintenance of pneumatic adjustment, as well as the high requirements for operators, will seriously affect production if the sensor fails and the machine is shut down for maintenance. The inaccuracy, time-consuming and adverse effects on the health and safety of operators caused by manual adjustment cannot be ignored. The present invention fundamentally changes this situation. Through the spiral suction and compression components, many problems of the traditional adjustment method are avoided, which has significant advantages in improving production efficiency, reducing costs, and ensuring the safety of operators.

[0029] Among them: the design of the regulating grooves penetrating each other in the present invention can make the remaining slitting knives move away from the center, which can avoid too many slitting knives from slitting the food packaging bags, thereby ensuring the accuracy of slitting. At the same time, the flexibility of this design lies in the selection of the number of slitting knives according to the sizes of different packaging bags, which not only improves the adaptability of the slitting machine to different products, but also helps to improve product quality, reduce product loss caused by improper slitting, and further improve production efficiency.

[0030] Among them: Through the setting of industrial cameras, the present invention realizes the function of transmitting images to the electric control panel, and the operator can better grasp the distance control through the enlarged image. In the traditional slitting machine operation, the operator can often only rely on experience and simple measuring tools to adjust the tool distance. The present invention uses the image transmission and magnification functions of the industrial camera to enable the operator to operate more intuitively and accurately, effectively improving the accuracy and efficiency of slitting.

[0031] To sum up, the present invention realizes the function of adjusting the slitting knife through the cooperation of the screw rod and the slitting knife and the setting of structures such as industrial cameras. The design of the spiral suction and compression assembly makes it unnecessary for the operator to enter the equipment for debugging, which greatly reduces the time cost of maintenance and debugging, and avoids the operational inconvenience and safety risks faced by the operator when entering the equipment. In addition, under the action of the industrial camera, the operator can observe the change in distance more intuitively, further improving the accuracy of the operation. Moreover, due to the threaded connection between the screw rod and the slitting knife, the self-locking characteristics of the thread are utilized, which avoids the problem of each slitting knife in the prior art needing to be equipped with a lock buckle. This design not only saves debugging time, but also reduces costs due to the lack of a lock buckle, thereby improving the performance and economic benefits of the slitting machine from many aspects.

[0032] 2. The present invention provides a spiral groove on the inner wall of the suction pipe so that the waste strips move in a spiral manner when being sucked in. When the waste strips move in a spiral manner, the waste strips in the pipe are equivalent to moving in a circular motion around a virtual cylindrical axis while moving forward along the pipe. This movement mode changes the force conditions of the waste strips in the pipe. When the waste strips reach the bend, due to their own spiral motion, a lateral force adapted to the curvature of the bend is generated, so that the waste strips can continue to move along the bend without being easily stuck. This improvement improves the stability of the waste strip recovery system, helps to continuously and stably suck the waste strips into the container for recycling and reuse, and improves the problem of low production efficiency caused by pipe blockage.

[0033] Compared with the prior art, the current technology causes many troubles to production companies when recycling waste strips in pipelines because the bends of the pipelines are prone to blockage. Companies either have to shut down for cleaning, which reduces production efficiency, affects the timely completion of orders, and causes huge economic losses; or continue production and then clean up the site, which increases labor costs and makes the cleaning process cumbersome and time-consuming. The present invention effectively avoids the problem of pipeline blockage by providing a threaded groove on the inner wall of the pipeline to enable the waste strips to move in a spiral. There is no need to worry about shutdown due to blockage or subsequent complicated cleaning work, which greatly improves production efficiency and reduces production costs, and has obvious advantages in overall production benefits.

[0034] Among them: a rotatable curved elliptical wheel is arranged on the surface of the notch groove to improve the smoothness of the waste strips entering. When the waste strips enter, they will fit the surface of the curved elliptical wheel and enter the inside of the suction pipe. In this process, due to the elliptical shape of the curved elliptical wheel, the surface of the waste strips will be concave. This concave allows the waste strips to better fit the inner wall of the suction pipe, thereby increasing the fit between the waste strips and the inner wall of the pipe, which can reduce the possibility of the waste strips colliding or getting stuck with the inner wall in the pipe, thereby further reducing the risk of blockage and ensuring the smoothness of the waste strip recovery process.

[0035] While achieving the above-mentioned effects, the present invention also has the following advantages: since the waste strips move in a spiral manner in the suction pipe, the waste strips themselves are constantly deformed during the movement. When entering the collection box, this continuous deformation increases the compression rate of the waste strips. The spiral movement causes the waste strips to be continuously twisted and squeezed in the pipe, so that the waste strips are compressed more tightly, and more waste strips can be accommodated in a unit space, thereby reducing the frequency of cleaning the inside of the collection box. The original multiple cleanings required due to the accumulation of waste strips can now be reduced to one cleaning, which greatly saves labor costs and cleaning time, and improves the practicality and economy of the entire waste strip recycling system.

[0049] 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.

[0050] It should be noted that the structure and working principle of the rewinding unit 13, the machine body 11, and the tension roller group belong to the existing technology, and the driving system only provides a power source for the unwinding roller 12, the rewinding unit 13 and the tension roller group, so it will not be repeated later.

[0051] Example 1, please refer to Figures 1 to 7As shown, a low-energy consumption and high-efficiency slitting machine includes a body 11, a reel 12 is installed on the outer surface of the body 11, a rewinding unit 13 is installed on the outer surface of the body 11 away from the reel 12, a plurality of slitting knives 14 are installed in the middle of the body 11, and a knife distance adjustment and image magnification component 2 is provided on the outer side of the slitting knife 14 for the convenience of the operator to adjust the knife and check the knife distance. The knife distance adjustment and image magnification component 2 includes two symmetrically distributed lead screws 23, a plurality of symmetrically distributed regulating grooves 27 and a plurality of matching shafts 29 fixedly connected to the outside of the slitting knife 14.

[0052] The screw rod 23 is used to move the slitting knife 14 thereon by rotating itself, and the threads of the two screw rods 23 are arranged in opposite directions.

[0053] The matching shaft 29 and the regulating groove 27 enable the remaining slitting knives 14 to move synchronously with the slitting knife 14 on the surface of the screw rod 23 through their own limiting effect. The regulating groove 27 farthest from the center of the body 11 has its tops interconnected, so that the operator can slide the slitting knife 14 and the matching shaft 29 away from the slitting area.

[0054] Please refer to Figures 4 to 6 As shown, the blade spacing adjustment and image magnification component 2 also includes two downward pressure cylinders 21, and the two downward pressure cylinders 21 are symmetrically fixedly connected to the surface of the body 11. The bottom of the output shaft of the downward pressure cylinder 21 is rotatably connected to the shaft body 22, and the ends of the two shaft bodies 22 close to each other are fixedly connected to the outer surface of the screw rod 23, and the ends of the two screw rods 23 close to each other are fixedly connected to the central axis 24, and the slitting knife 14 closest to the center of the central axis 24 is rotatably connected to its surface, and the slitting knives 14 on both sides of the slitting knife 14 at the center are threadedly connected to the outer surface of the screw rod 23, and the remaining slitting knives 14 are symmetrically slidably connected to the outer surface of the shaft body 22, and the body The outer surface of 11 is symmetrically fixedly connected to the limiting groove body 25, and the limiting groove body 25 is slidably connected to the regulating plate 26. The regulating grooves 27 are symmetrically penetrated through the surface of the regulating plate 26, and the matching shafts 29 are slidably connected to the inside of the regulating grooves 27. The tops of several slitting knives 14 are rotatably connected to the upper shaft 210. The regulating plate 26 penetrates the surface symmetrically with radial grooves 28. The surface of the upper shaft 210 extends to the inside of the radial groove 28 and is symmetrically fixedly connected to the limiting shaft. The limiting shafts are slidably connected to the inside of the radial groove 28. The top of the upper shaft 210 is fixedly connected to a receiving platform 211, and an industrial camera 212 is installed on the top of the receiving platform 211.

[0055] It should be noted that an electric control panel is installed on the outside of the machine body 11, and the electric control panel electrically controls the start and stop of the pressing cylinder 21. The electric control panel is electrically connected to the industrial camera 212. A tension roller group is installed on the outside of the machine body 11. A positioning module is installed on the top of the machine body 11, which is specifically implemented as a ray positioner. The machine body 11 has a built-in drive system, and the photoelectric module is electrically connected to the electric control panel. The drive system is electrically controlled to start and stop by the electric control panel. The rewinding unit 13 includes two rewinding rollers, which are symmetrically installed on the outer surface of the machine body 11 in an upper and lower position. The tension roller group includes The invention comprises a plurality of tension rollers, which are all rotatably connected to the outer surface of the machine body 11. The driving system comprises three drive motors and a tension motor. The three drive motors are respectively installed on the unwinding roller 12 and the two rewinding rollers. The tension motor is installed on any one of the tension rollers. The other tension rollers are connected to the tension motor by belt transmission. Two knife rollers rotatably connected to the outer surface of the machine body 11 are arranged below the slitting knife 14. The center of the blade of the slitting knife 14 is between the two knife rollers. The pitch of the screw rod 23 is set to p, the number of rotations of the screw rod 23 is n, and the screw rod 2 The moving distance of the slitting knife 14 on the surface of the screw 23 along the axial direction of the screw 23 is d1=np. For the slitting knife 14 in the regulating groove 27 closest to the center, let the moving distance in the regulating groove 27 be d2. According to the geometric relationship, d2=sinθh. Since the moving distance of the slitting knife 14 on the surface of the screw 23 and the slitting knife 14 in the regulating groove 27 closest to the center is d=d2, then np=sinθh. Since h=d1=np, np=sinθnp. Simplifying, sinθ=1, that is, θ=90∘, but in actual situations Due to the existence of mechanical friction, connection flexibility and other factors, θ should be close to 90∘, then 85∘≤θ≤90∘. In addition, the length of the regulating groove 27 is set to L. In order to ensure that the slitting knife 14 in the regulating groove 27 closest to the center can complete the movement of the same distance as the surface of the screw rod 23 in the regulating groove 27, it is necessary to satisfy d2≤L. Substituting d2=sinθh, we get sinθnp≤L. A scale line is set on the top of the upper shaft 210, which is used for the industrial camera 212 to enlarge and transmit the image so that the operator can intuitively observe the moving distance of the slitting knife 14.

[0056] Please refer to Figure 2 and Figure 4As shown, it should be noted that the shaft body 22 near the electric control panel is cut off on the side near the downward pressure cylinder 21, and four bevel gears and a cross rod are provided at the cut portion. The bevel gears on the left and right sides are rotatably connected to the two cut surfaces of the shaft body 22, and the four bevel gears are meshed with each other. At the same time, the bevel gears on the left and right sides are rotatably connected to the two ends of the cross rod on the side close to each other, and the front and rear sections of the cross rod are rotatably connected to the surfaces of the bevel gears on the front and rear sides respectively. At the same time, the bevel gear on the front side extends to the side near the electric control panel and is fixedly connected to a hand wheel. The bevel gears, the cross rod and the hand wheel can form a power transmission system. The operator only needs to turn the hand wheel to rotate the shaft body 22 through the power transmission of the bevel gears.

[0057] Specifically, the raw material roll of the food packaging bag to be cut is first installed on the unwinding roller 12 to ensure that the material roll can be unwound smoothly. The material released from the unwinding roller 12 is then passed around the two knife rollers, and the material continues to pass around the tension rollers in the tension roller group to keep the tension of the material stable during the slitting process. Finally, the material passing around the tension roller group is guided to the two rewinding rollers respectively.

[0058] On the rewinding roller, use tape to ensure that the material end is firmly adhered to the rewinding roller surface, preparing for the subsequent rewinding process.

[0059] At this time, the operator needs to turn the handwheel, which transmits power to the shaft 22 through the bevel gear and the cross rod, and makes it rotate. At this time, the rotation of the shaft 22 drives the downward pressure cylinder 21 and the screw rod 23 to rotate synchronously. Since the middle slitting knife 14 is limited by the upper shaft 210, the middle slitting knife 14 will not move, and the slitting knife 14 on the surface of the screw rod 23 will start to slide on the surface of the screw rod 23 due to the cooperation of the thread and the limitation of the upper shaft 210.

[0060] Furthermore, during the movement of the slitting knife 14 on the surface of the screw rod 23, the matching shaft 29 on its surface will conflict with the regulating groove 27. Since the regulating plate 26 is limited by the limiting groove 25 and can only move up and down, in order to adapt to the movement of the slitting knife 14 on the surface of the screw rod 23, the regulating groove 27 inside the regulating plate 26 will continuously conflict with the matching shaft 29, causing the regulating plate 26 to slide vertically. Similarly, the slitting knives 14 on both sides will also move synchronously.

[0061] During this process, the industrial camera 212 on the receiving table 211 will transmit the enlarged image to the electronic control panel in real time. At this time, the operator can judge the moving distance of the slitting knife 14 based on the enlarged image and the scale line on the top of the upper shaft 210. At the same time, the operator also needs to check the moving distance of the slitting knife 14 with the size of the food packaging bag on the list.

[0062] When the check is completed, the operator can control the extension of the output shaft of the collection box 31 through the electrical control panel. At this time, the collection box 31 will drive the remaining structures of the spiral suction and compression assembly 3 to descend. At this time, the slitting knife 14 will contact the surface of the food packaging bag. Then the operator can start the drive system and other electrical appliances, and the food packaging bag can be transported, and the slitting effect can be achieved under the action of the slitting knife 14.

[0063] It should be noted that when the size of the food packaging bag is too large and the slitting knives 14 on both sides are not needed, the operator adjusts the distance of the slitting knives 14 according to the above steps. When the matching shaft 29 moves to the top of the regulating groove 27, that is, the part where the two regulating grooves 27 are connected to each other, the operator can manually slide the slitting knives 14 on both sides and slide them to the side of the regulating groove 27 farthest from the center. At this time, the slitting knife 14 is located at the end of the regulating plate 26, and the slitting knife 14 will not cut the food packaging bag.

[0064] Example 2, based on Example 1, please refer to Figures 8 to 10 As shown, a spiral suction and compression assembly 3 is arranged below the slitting knife 14, and the spiral suction and compression assembly 3 includes two collecting boxes 31, which are symmetrically installed inside the body 11, and a fan 32 is symmetrically installed inside the body 11, and the output end of the fan 32 is connected to the inside of the collecting box 31, and the fan 32 is electrically controlled to start and stop by the electric control panel. A transfer block is arranged below the slitting knife 14, and a fixing rod is fixedly connected between the transfer block and the outer surface of the body 11, and a suction pipe 34 is fixedly connected on both sides of the transfer block, and the end of the suction pipe 34 away from the middle block 33 is connected to the inside of the collecting box 31, and the side of the suction pipe 34 close to the middle block 33 is solid, and a threaded groove 35 is opened on the inner wall of the suction pipe 34, and a plurality of notched grooves 36 are opened through the top of the suction pipe 34, and a plurality of rotating frames 37 are fixedly connected to the top of the suction pipe 34 in an arc shape, and every two rotating frames 37 are arranged as a group, and a curved elliptical wheel 38 is rotatably connected between each group of rotating frames 37.

[0065] Specifically, in the process of slitting food packaging bags, waste is inevitably generated. As the slitting operation proceeds, after the waste part of the food packaging bag passes through the knife roller, due to the effect of its own gravity, the waste begins to gradually slide down until it reaches the suction pipe 34 and the notch groove 36. As mentioned in Example 1, the electrical control panel has started the electrical appliances of the entire slitting machine, including the fan 32. At this time, the fan 32 generates a strong negative pressure inside the collection box 31. The negative pressure acts on the end of the waste through the suction pipe 34 and the notch groove 36 opened thereon, so that the waste is effectively sucked into the suction pipe 34 and the notch groove 36.

[0066] When the waste enters the suction pipe 34, it will come into contact with the curved elliptical wheel 38 on its surface, and then the waste will fit tightly with the curved elliptical wheel 38 when entering the notch groove 36, and deform inwardly in accordance with the elliptical shape of the curved elliptical wheel 38 itself. This deformation not only helps the waste to fit better with the inner wall of the suction pipe 34, but also lays the foundation for its subsequent spiral movement.

[0067] When the waste material adheres to the curved elliptical wheel 38 and deforms, it will enter the thread groove 35. Since the thread groove 35 is provided inside the suction pipe 34, when the waste material is sucked by negative pressure, part of the air will move along the trajectory of the thread groove 35, that is, the air forms a spiral ring on the inner wall of the suction pipe 34, and then the spiral ring will pull the waste material to perform a spiral motion, thereby generating a lateral force that is adapted to the curvature of the bend of the suction pipe 34. This lateral force enables the waste material to continue to move along the bend instead of accumulating or clogging at the bend. Therefore, the existence of the thread groove 35 not only ensures the smooth movement of the waste material, but also greatly improves the efficiency of waste collection.

[0068] It should be noted that the waste in spiral motion is constantly bent and compressed inside the suction pipe 34, so the volume of the waste itself gradually decreases, so that when entering the collection box 31, more waste can be accommodated in a unit space. This compression effect not only increases the collection density of the waste, but also reduces the space occupied by the waste during the collection process. At the same time, since the waste moves in a spiral manner, it is not easy to get blocked in the suction pipe 34 or the collection box 31, thereby ensuring the continuity and stability of waste collection.

[0069] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
