Description

Technical Field

[0001] This utility model relates to the field of packing strap processing technology, and in particular to a cutting device for packing strap processing. Background Technology

[0002] Packing straps, also known as binding straps, are made primarily of polyethylene and polypropylene resin, though some are made from nylon and polyester, through a unidirectional extrusion process. Besides sealing and binding corrugated boxes, they can also be used to bundle materials, fruits, etc. They are divided into PP strapping and PET strapping, produced using polypropylene and PET polyester respectively, and are suitable for packing objects of different weights.

[0003] A cutting device for strapping processing, with authorized publication number CN220925854U, relates to the field of strapping processing. It includes a base, with a feeding roller frame and a receiving roller frame on the top of the base. A movable seat is connected to the top of the base, and a first fixed frame is connected to the top of the movable seat. A first rotating shaft is connected inside the first fixed frame, and a first guide roller is connected to the outer wall of the first rotating shaft. A second fixed frame is connected to the top of the base, with a second rotating shaft connected inside the second fixed frame, and a second guide roller connected to the outer wall of the second rotating shaft. This invention uses a motor to drive a threaded rod to rotate. When the threaded rod rotates, it pulls a movable block, which in turn pulls a second pressure plate. The second pressure plate pulls a limiting plate, which in turn pulls the first rotating shaft. The first rotating shaft pulls the first fixed frame, which in turn pulls the movable seat. This movement of the movable seat releases the tension generated during strapping winding, thus preventing damage to the strapping.

[0004] Regarding the aforementioned technologies, the existing strapping tape cutting devices have the following drawbacks: although these devices can adjust the tension during strapping tape winding and protect the strapping tape, the strapping tape comes into contact with the equipment and rubs during conveying, guide wheel rolling, and tension adjustment, generating static electricity and attracting dust to the surface, which affects the cutting accuracy. Therefore, this utility model provides a strapping tape cutting device. Utility Model Content

[0005] The purpose of this application is to provide a cutting device for processing packing straps, so as to solve the problem mentioned in the background art that the packing straps generate static electricity and attract dust on the surface during the process of conveying, guide wheel rolling, tension adjustment, etc., which affects the cutting accuracy.

[0006] To achieve the above objectives, this application provides the following technical solution: a cutting device for processing packing straps, comprising a base plate, with fixed frames fixedly connected to both ends of the base plate, and an electrostatic elimination component provided on the inner wall side of the fixed frame; the electrostatic elimination component includes an ion fan disposed on the inner wall side of the fixed frame, a high-voltage ionization component disposed on the inner side of the ion fan, and a metal plate fixedly connected to the top of the base plate, with a slot formed on the inner side of the metal plate, the edges of the slot being arc-shaped.

[0007] Preferably, a pair of fixing plates are fixedly connected to the top of the substrate, and a metal guide wheel is rotatably connected between the pair of fixing plates.

[0008] Preferably, a conductive rubber wheel is provided between the pair of fixed plates, and a slider is fixedly connected to one end of the conductive rubber wheel.

[0009] Preferably, one of the fixing plates has a groove on its inner side that matches the slider, a positioning frame is fixedly connected to the bottom of the base plate, a hydraulic push rod is fixedly connected to the inner wall of the positioning frame, and the output end of the hydraulic push rod is fixedly connected to the slider.

[0011] Preferably, a push plate is fixedly connected to the output end of the hydraulic telescopic rod, a cutting blade is fixedly connected to the bottom of the push plate, and a receiving plate adapted to the cutting blade is fixedly connected to the top of the base plate.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] In this invention, by setting up an electrostatic elimination component, positive and negative ions are sprayed out by an ion fan to neutralize static electricity. Further discharge is achieved by contacting the packing strap with a metal plate. By adding conductive rubber wheels or metal guide wheels on the packing strap path, static electricity is discharged more thoroughly, reducing the impact on the cutting of the packing strap.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example 1: Reference Figure 1-4The illustrated cutting device for processing packing tape includes a base plate 1. The base plate 1 serves as the basic load-bearing structure of the entire device, providing a stable mounting platform for other components and ensuring that the positions of each component are fixed during operation, thus making the overall structure of the device stable. Fixing frames 2 are fixedly connected to both ends of the base plate 1. The fixing frames 2 support and fix the static elimination components, and also strengthen the overall structure of the device, enhancing its stability. The inner wall of the fixing frame 2 is equipped with an electrostatic elimination component. This component includes an ion fan 3 mounted on the inner wall of the fixing frame 2. The ion fan 3 generates ionized air to neutralize static electricity on the surface of the packing strap, preventing the static electricity from attracting dust and impurities, thus avoiding affecting the quality of the packing strap and subsequent processing. A high-voltage ionization component 18 is mounted inside the ion fan 3, and multiple ion nozzles are mounted outside the high-voltage ionization component 18. The high-voltage ionization component 18 generates high voltage to ionize the air, providing the necessary ion source for the ion fan 3, ensuring that the ion fan 3 continuously and effectively performs its electrostatic elimination function. A metal plate 4 is fixedly connected to the top of the base plate 1. The metal plate 4 can conduct static electricity, further eliminating static electricity on the packing strap. Simultaneously, its hard material can withstand the friction and pressure of the packing strap during processing, ensuring the durability of the device. A slot 5 is formed on the inner side of the metal plate 4, providing a channel for the packing strap to run. The edges are arc-shaped. The surface design reduces friction between the strapping and the edge of the slot during operation, preventing damage to the strapping surface and extending its service life. A pair of fixing plates 6 are fixedly connected to the top of the base plate 1. The fixing plates 6 are used to fix the rotation shaft of the metal guide wheel 7, ensuring that the metal guide wheel 7 can rotate stably. They also provide a base for the installation and positioning of the conductive rubber wheel 8. A metal plate 4 is rotatably connected between the pair of fixing plates 6. The metal guide wheel 7 can guide the running direction of the strapping. Its metal material has good wear resistance and strength, and can adapt to the long-term, high-frequency operation of the strapping, ensuring the stability and smoothness of the strapping operation. A conductive rubber wheel 8 is set between the pair of fixing plates 6. The conductive rubber wheel 8 can further conduct static electricity on the strapping by contacting it, eliminating the potential for static electricity. At the same time, its rubber material has a certain elasticity and can provide appropriate pressure when in contact with the strapping, ensuring the smooth operation of the strapping. A slider 12 is fixedly connected to one end of the conductive rubber wheel 8. The slider 12 allows the conductive rubber wheel 8 to slide between a pair of fixed plates 6, which facilitates the adjustment of the distance between the conductive rubber wheel 8 and the metal guide wheel 7 to meet the processing requirements of different specifications of packing straps and improve the versatility of the device.

[0023] Example 2: Reference Figure 1-4Based on the same concept as in Embodiment 1 above, this embodiment further proposes that a groove 9 adapted to the slider 12 is provided on the inner side of one of the fixing plates 6. The groove 9 provides a sliding track for the slider 12, ensuring that the slider 12 can move stably along a specific path. A positioning frame 10 is fixedly connected to the bottom of the base plate 1. The positioning frame 10 is used to fix the position of the hydraulic push rod 11 so that it remains stable during operation. A hydraulic push rod 11 is fixedly connected to the inner wall of the positioning frame 10. The hydraulic push rod 11 serves as a power source and drives the slider 12 to slide in the groove 9 through extension and retraction. The output end of the hydraulic push rod 11 is fixedly connected to the slider 12, so that the extension and retraction of the hydraulic push rod 11 can directly drive the slider 12 to move. A support frame 13 is fixedly connected to the top of the base plate 1. The support frame 13 supports the hydraulic extension rod 1. The function of component 4 is to ensure stable installation. A hydraulic telescopic rod 14 is installed through the inner side of the support frame 13. The hydraulic telescopic rod 14 is a component that provides vertical power and can move the push plate 15 up and down by telescoping. The output end of the hydraulic telescopic rod 14 is fixedly connected to the push plate 15. The push plate 15 is used to transmit the power of the hydraulic telescopic rod 14 to drive the cutting blade 16 to perform the cutting action. The bottom of the push plate 15 is fixedly connected to the cutting blade 16. When the cutting blade 16 moves downward under the drive of the hydraulic telescopic rod 14, it performs the cutting operation. A receiving plate 17 adapted to the cutting blade 16 is fixedly connected to the top of the base plate 1. The receiving plate 17 provides support and a cutting platform for the cutting blade 16, ensuring the stability and accuracy of the cutting process.

[0024] The working principle of this utility model is as follows: The strapping is passed sequentially through the slot 5 inside the metal plate 4, the metal guide wheel 7, and the conductive rubber wheel 8. The metal plate 4 allows the strapping to contact the inner wall of the slot 5 and discharge static electricity before cutting. The conductive rubber wheel 8 or the metal guide wheel 7 are installed on the path of the strapping to help discharge static electricity and prevent the accumulation of static electricity due to friction. The high-voltage ionization component 18 is controlled to generate positive and negative ions, which are sprayed out through multiple ion nozzles and then sprayed out by the ion fan 3 to achieve the effect of neutralizing static electricity. During the guiding process, the hydraulic push rod 11 is controlled to drive the slider 12 and the conductive rubber wheel 8 to move, thereby achieving tensioning and loosening of the strapping and preventing the strapping from being stretched or even broken, or from not being tightly wound.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
