Description

Technical Field

[0001] This utility model relates to a device for automatically applying oil to the main seal of a fabric packaging machine, belonging to the field of packaging equipment technology. Background Technology

[0002] In the production process of fabric roll packaging, a packaging machine is used to wrap a film around the fabric roll, and then the film is sealed by heating copper. To prevent the film from sticking to the copper blade and blade holder during heat sealing and affecting the sealing, lubricating oil is usually applied to the surface of the copper blade and blade holder to form a protective layer. Currently, the fabric roll packaging machines used in the industry generally use a periodic manual oiling method to lubricate the copper blade and blade holder. However, the oiling cycle is uncertain. If the film sticks to the blade due to forgetting to oil, the wrapping cannot be completed smoothly. Personnel need to handle the waste film on-site and re-wrap the film, which is time-consuming, labor-intensive, and wasteful of film, affecting production efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a device for automatic oiling of the main seal of a cloth packaging machine, which can automatically apply oil in a quantitative manner and can overcome the shortcomings of the prior art.

[0004] The technical solution of this utility model is: a device for automatic oiling of the main seal of a cloth packaging machine, comprising a controller, a drive mechanism, an oil conveying mechanism, and an oiling mechanism including an oil spray nozzle. The oiling mechanism is connected to the drive mechanism and is driven to reciprocate along the length of the blade holder. The oil spray nozzle of the oiling mechanism is connected to the oil conveying mechanism and is supplied with lubricating oil to spray onto the surface of the blade holder. The controller is connected to the drive mechanism and the oil conveying mechanism respectively, and controls the operation of the drive mechanism and the oil conveying mechanism.

[0005] Further, a foreign object detection mechanism is included, which comprises a pair of sensors disposed at both ends of the tool holder.

[0006] Furthermore, the oiling mechanism and the base are provided with a cooperating avoidance mechanism. A pair of sensors are in close contact with the surface of the blade holder. The movement of the oiling mechanism causes the oil nozzle to switch between a working position between the two sensors and a waiting position outside the blade holder. In the working position, the oil nozzle and the pair of sensors are on the same straight line. During the switching between the working position and the waiting position, the avoidance mechanism is connected and cooperates to change the height of the oil nozzle to avoid collision with the sensors.

[0007] The further mentioned avoidance mechanism includes a guide plate with a slope mounted on the base, and the oiling mechanism includes a connecting plate and a connecting assembly slidably connected to the connecting plate. The oil nozzle is mounted on the connecting assembly, and the connecting assembly has a guide member that cooperates with the guide plate. When the oiling mechanism passes the guide plate, the guide member connects with the guide plate, causing the connecting assembly to slide relative to the connecting plate and change the height of the oil nozzle.

[0008] Furthermore, an elastic reset member is provided between the connecting component and the connecting plate. During the process of the connecting component moving relative to the connecting plate, the elastic reset member further deforms to generate elastic force. After the connecting component separates from the guide plate, the elastic force pushes the connecting component to move down and reset to the initial position.

[0009] The device further includes a collection assembly with a collection groove located below the injector when the injector is in the waiting position, for collecting lubricating oil dripping from the injector.

[0010] Furthermore, the collection tank is connected to the oil delivery mechanism.

[0011] The further described drive mechanism includes a drive motor, a linear guide rail, a guide rail slider, and a transmission assembly. The linear guide rail is mounted on the base and parallel to the tool holder. The guide rail slider slides on the linear guide rail and is connected to the drive motor through the transmission assembly. A second drive mechanism connected to the oil brushing mechanism is provided on the guide rail slider.

[0012] The connecting assembly further includes a nozzle mounting plate, a nozzle guide plate, and an oil pipe guide tube. The oil pipe guide tube is slidably connected to the connecting plate. The nozzle is mounted on the nozzle mounting plate. The nozzle mounting plate is mounted on the nozzle guide plate and can be adjusted horizontally relative to the nozzle guide plate. The nozzle guide plate is mounted on the oil pipe guide tube and can be adjusted vertically relative to the oil pipe guide tube.

[0013] By implementing this utility model, the controller controls the operation of the oil delivery mechanism to deliver lubricating oil to the nozzle of the oil brushing mechanism for spraying and brushing. At the same time, it controls the operation of the drive mechanism to drive the oil brushing mechanism to reciprocate along the length of the cutter holder, thereby realizing the automatic quantitative and uniform spraying of lubricating oil on the surface of the cutter holder.

[0018] Embodiments of this utility model: such as Figures 1 to 3 As shown, a device for automatic oiling of the main seal of a fabric packaging machine is disclosed. This device oils the surface of a blade holder 1 located on a base. It includes a controller, a drive mechanism, an oil delivery mechanism, and an oiling mechanism containing an oil spray nozzle 3. The base includes several columns 2 and a crossbeam 5 mounted on the columns 2 parallel to the blade holder 1. The oil delivery mechanism includes a lubricating oil pump 4 mounted on the columns 2. The oil outlet of the lubricating oil pump 4 is connected to the oil spray nozzle 3 via a flexible oil pipe. The controller is connected to both the drive mechanism and the lubricating oil pump 4. The controller controls the operation of the drive mechanism and the lubricating oil pump 4 by setting a frequency. The drive mechanism drives the oiling mechanism to reciprocate along the crossbeam 5. The oil spray nozzle 3 is located above the blade holder 1. The lubricating oil pump 4 delivers lubricating oil to the oil spray nozzle 3 of the oiling mechanism to spray and brush the blade holder 1. The controller sets the operating frequency through a program to achieve automatic, quantitative, and uniform spraying of lubricating oil onto the surface of the blade holder 2 at regular intervals.

[0019] As a preferred embodiment, a foreign object detection mechanism is included. The foreign object detection mechanism includes a pair of sensors 22 disposed at both ends of the cutter holder 1. One of the sensors 22 can be a transmitting sensor and the other can be a corresponding receiving sensor. The sensor is connected to the controller and can detect foreign objects on the cutter holder 1 in a timely manner by transmitting and receiving light. The controller then triggers an alarm to prevent foreign objects from affecting the film sealing process.

[0020] As a preferred embodiment, for accurate detection of foreign objects on the tool holder 1, a pair of sensors 22 are closely attached to the surface of the tool holder 1. To better brush the tool holder 1, the oil spraying mechanism requires the oil nozzle 3 to also be close to the surface of the tool holder 1 during brushing. The oil nozzle 3 switches between a working position between the two sensors 22 and a waiting position outside the tool holder 1. When in the working position, it may block the light emitted by the sensors 22. To ensure the normal operation of the sensors 22 and to avoid affecting the film sealing of the fabric roll, after the lubricating oil is sprayed, the oil spraying mechanism needs to be moved to the waiting position where the oil nozzle 3 is no longer between the two sensors 22. However, if the oil spraying mechanism is only moved by the drive mechanism, the oil nozzle 3 will collide with the sensor 22 at one end of the tool holder 1 when passing it. Therefore, the oil spraying mechanism and the crossbeam 5 are equipped with... The avoidance mechanism, which is connected to the sensor 22, changes the height of the nozzle 3 and the sensor 22 to avoid collision as the nozzle 3 passes the sensor 22. Specifically, the avoidance mechanism includes a guide plate 6 with a slope installed on the crossbeam 5, and the oiling mechanism includes a connecting plate 7 and a connecting component that slides on the connecting plate 7. The nozzle 3 is installed on the connecting component, which has a guide roller 21 that is connected to the guide plate 6. The guide roller 21 is the guide component. When the oiling mechanism passes the guide plate 6, the guide roller 21 connects with the slope of the guide plate 6, causing the connecting component to slide relative to the connecting plate 7. During the movement from the working position to the waiting position, the nozzle 3 is raised and its height is increased. During the movement from the waiting position to the working position, the nozzle 3's height decreases to a position close to the tool holder 1.

[0021] As a preferred embodiment, a compression spring 8 is provided between the connecting assembly and the connecting plate 7. The compression spring 8 serves as the elastic reset element. The connecting assembly includes an oil nozzle mounting plate 9, an oil nozzle guide plate 10, an oil pipe guide tube 11, a guide slider 12, and a spring tube 13. The oil nozzle 3 is mounted on the oil nozzle mounting plate 9, which is mounted on the oil nozzle guide plate 10. The guide slider 12 is fixed to the oil pipe guide tube 11 and slides with the spring tube 13. The spring tube 13 is fixed to the connecting plate 7. The compression spring 8 is mounted on the spring tube 13, pressing down on the guide slider 12. A guide roller 21 is mounted on the guide slider 12. The flexible oil pipe connected to the lubricating oil pump 4 passes through the entire oil pipe guide tube 11 from bottom to top and then connects to... The nozzle 3 forms an oil outlet pipe. During the process of moving from the working position to the waiting position, the guide roller 21 is connected to the slope of the guide plate 6. The guide slider 12 drives the nozzle 3 to move upward. During this process, the compression spring 8 is compressed. During the process of moving from the waiting position to the working position, the compression spring 8 extends, causing the nozzle 3 to reset and remain close to the tool holder 1. The action of the compression spring 8 makes the lifting and lowering smooth and can accurately reset. The nozzle mounting plate 9 is provided with a long slot. The nozzle 3 can be adjusted horizontally relative to the nozzle mounting plate 9 and fixed by fasteners. The nozzle guide plate 10 can be adjusted vertically relative to the oil pipe guide tube 11 and fixed by fasteners. This allows the nozzle 3 to be adjusted in the initial position as needed to better adapt to the spraying of the tool holder 1.

[0022] As a preferred embodiment, a collection assembly is included, which includes a collection tank 14. The collection tank 14 is mounted on the crossbeam 5 via a collection tank bracket 15. When the fuel injector 3 is in the waiting position, it is above the collection tank 14. The collection tank 14 is provided with an oil outlet, which is connected to the lubricating oil pump 4 via an oil pipe. The collection tank 14 collects the lubricating oil dripping from the fuel injector 3 and delivers it to the fuel injector 3 for spraying again via the lubricating oil pump 4, thereby realizing the recycling of lubricating oil.

[0023] As a preferred embodiment, the drive mechanism includes a drive motor 15, a linear guide rail 16, a guide rail slider 17, and a transmission assembly. The transmission assembly includes a synchronous pulley 18, a synchronous belt 23, and a synchronous belt tensioner. The linear guide rail 16 is mounted on the crossbeam 5, and the guide rail slider 17 slides on the linear guide rail 16 and can move along the linear guide rail 16. The drive motor 15 is mounted on one end of the crossbeam 5, and the synchronous belt tensioner is fixed on the other end of the crossbeam 5. The synchronous pulley 18 is respectively located on the drive motor 15 and the synchronous belt tensioner and connected by the synchronous belt 23. The guide rail slider 17 is fixed by a cylinder. Plate 19, cylinder fixing plate 19 is provided with cylinder 20 connected to the oil brushing mechanism. Cylinder 20 is the second driving mechanism. Drive motor 15 drives guide rail slider 17 to move horizontally back and forth on linear guide rail 16, so that the oil spray nozzle 3 of the oil brushing mechanism slides and sprays on the knife holder 1 between the two sensors 22. When the oil brushing mechanism is in the initial spraying position at one end of the knife holder 1, the cylinder 20 pushes the oil brushing mechanism to move and cooperate with the guide plate 6 to switch between the working position and the waiting position. In this way, the length of linear guide rail 16 and knife holder can be made to correspond, without increasing the length of the equipment.
