However, there are some problems with the current equipment for cutting the fruit net, such as the low cut flatness and complex movements caused by the blade or scissor cutting method, and the equipment using the hot melt wire for cutting cannot adjust the tension, which makes the hot melt wire easy to loosen after a long time of use, thus affecting the cutting effect. Utility Model Content

[0003] In order to solve the problem that the existing hot melt wire cutting device cannot effectively adjust the tension of the hot melt wire, thereby affecting the cutting effect, the purpose of the utility model is to provide a hot melt wire cutting device with adjustable ends, which can adjust the tension of the hot melt wire to ensure the flatness and accuracy of the cutting.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hot melt net cutting device with adjustable ends, comprising a base and a hot fuse for cutting a fruit net, wherein the two ends of the hot fuse are respectively connected to a positive and negative power supply, and also comprising two adjustable fuse holders arranged on the base, wherein the adjustable fuse holders comprise a fixed block and a movable block, wherein the movable blocks of the two adjustable fuse holders are respectively fixed at the two ends of the hot fuse and can move relative to the fixed block along the length direction of the hot fuse, and the movable blocks of the two adjustable fuse holders are moved away from each other to tension the hot fuse.

[0005] In the technical solution, the two ends of the thermal fuse are connected to a positive power supply and a negative power supply respectively. When the power is turned on, the thermal fuse generates heat, and the fruit net can be cut. The moving blocks of the two adjustable fuse holders are respectively fixed at the two ends of the thermal fuse. By adjusting the moving blocks of the two adjustable fuse holders to move away from each other, the thermal fuse is tensioned, thereby realizing the control of the tension of the thermal fuse. The device can keep the thermal fuse in a straight state, which is crucial to the working effect of the thermal fuse, because it can ensure that when cutting the fruit net, the relaxation of the thermal fuse is effectively avoided, thereby ensuring the flatness and accuracy of the cutting.

[0006] The utility model is further configured such that: the base or the fixed block is connected to the moving block by a fastener to lock the moving block. Through this configuration, the moving block can be easily adjusted as needed. By adjusting the position of the moving block and locking it, the user can ensure that the thermal fuse is always in the best straight state. This straight state is crucial to improving the accuracy and efficiency of cutting, because it can ensure that the thermal fuse remains stable and does not loosen when cutting the fruit net.

[0007] The utility model is further configured as follows: a dovetail guide structure is provided on the moving block, and a dovetail groove adapted to the dovetail guide structure is provided on the fixed block. This configuration not only ensures the smooth and accurate sliding of the moving block on the fixed block, but also effectively prevents the moving block from shaking or deviating from the predetermined track during the movement, thereby ensuring the accuracy of the thermal fuse tension adjustment; at the same time, this design also greatly enhances the connection stability between the moving block and the fixed block, making the entire device more reliable and durable during use.

[0008] The utility model is further configured as follows: the adjustable fuse holder is movably arranged on the base. Through this configuration, the user only needs to perform simple operations to easily move the thermal fuse to a new cutting position, thereby improving the speed and convenience of cutting.

This synchronous movement design brings great convenience and efficiency. The user only needs to perform simple operations to easily move the thermal fuse to a new cutting position without the tedious manual readjustment of the position of each fuse holder. This not only greatly saves time and energy, but also improves the accuracy and consistency of cutting. It can quickly and accurately complete the cutting task of the fruit net, bringing users a more efficient and convenient use experience.

[0011] The utility model is further configured as follows: the hot melt cutting mesh device also includes a driving member, the driving member is connected to the first bracket or the second bracket through a fastener, and the driving member and the transmission shaft are connected through a coupling. The driving member is firmly connected to the first bracket or the second bracket through the fastener, ensuring its stability and reliability during operation. At the same time, the driving member and the transmission shaft are precisely connected through the coupling, so that the driving member can efficiently and accurately drive the transmission shaft to rotate.

[0012] The utility model is further configured as follows: a limit adjustable bolt is provided on the side of the adjustable fuse holder away from the thermal fuse, and a sensor for sensing the limit adjustable bolt is provided on the base. Through this configuration, the device has the function of real-time monitoring and adjustment. When the position of the adjustable fuse holder changes, the sensor can immediately sense the position change of the limit adjustable bolt, and adjust the working state of the device in real time accordingly. By adjusting the limit adjustable bolt, the user can accurately control the position of the adjustable fuse holder, thereby ensuring that the thermal fuse is in the best working state.

[0013] The utility model is further configured as follows: an insulating cover and a ceramic terminal block for connecting the thermal fuse and the adjustable fuse block are provided on the adjustable fuse holder, and the insulating cover, the ceramic terminal block and the moving block are all connected by fasteners. Through this configuration, not only a stable connection between the thermal fuse and the adjustable fuse holder is ensured, but also excellent insulation protection is provided. The insulating cover effectively limits and fixes the position of the thermal fuse, isolating it from other components, thereby preventing the risk of short circuit that may be caused by the conduction of the thermal fuse. At the same time, the high temperature resistance of the ceramic terminal block also ensures that the wiring part will not be damaged by high temperature during the operation of the thermal fuse. The insulating cover, the ceramic terminal block and the moving block are all connected by fasteners, ensuring the stability and reliability of the entire adjustable fuse holder. This design not only improves the safety of the device, but also extends its service life.
