[0039] Embodiment:

[0040] A hot melt device includes a frame body 10, a cylinder 20, a plastic part 80, and a fixing part 90. The cylinder 20 is arranged at the upper end of the frame body 10. A hot melt component 30 is arranged at the extending end of the cylinder 20. A fixing component 40 is arranged on the top surface of the lower end of the frame body 10. A supporting component 50 for limiting the plastic part 80 is arranged inside the fixing component 40. The plastic part 80 is installed on the top of the supporting component 50. The fixing part 90 is vertically opposed to the hot melt component 30. Among them, the fixing part 90 is detachably connected to the top of the plastic part 80.

[0041] It should be noted that considering the potential safety hazards that may be brought by high-temperature components during the hot melt process, the outside of the hot melt component 30 can be wrapped with materials with good high-temperature resistance and heat insulation effects to effectively prevent operators from being directly contacted and scalded. Among them, the supporting component 50 in the fixing component 40 can be made of high-strength materials according to actual situations, so that it can withstand the temperature changes and mechanical stresses during the hot melt process, further ensuring the stability of the plastic part 80 during the processing, and avoiding processing failures or safety accidents caused by shaking or misalignment.

[0042] Specifically, a detachable connection method, such as a snap or socket connection, is adopted between the fixing member 90 and the plastic member 80. This design enables easy replacement of plastic members 80 of different specifications or types without complex adjustments, further improving production efficiency and flexibility. By configuring the support member 50 to stabilize the position of the plastic member 80, this support member 50 is vertically opposed to the hot-melt member 30, ensuring that during the work process, the cylinder 20 drives the hot-melt device to accurately move downward in the vertical direction, thereby precisely heating the plastic member 80 and promoting the plastic material to smoothly reach the molten state. Subsequently, an appropriate pressure is applied to deform the molten plastic material and achieve a stable connection with the fixing member 90 after cooling.

[0043] In combination with the accompanying drawings of the specification Figures 1-12 As shown, the frame body 10 includes a connecting column 110, a fixed top plate 120, and a fixed bottom plate 130. The fixed top plate 120 and the fixed bottom plate 130 are respectively installed at the top and bottom of the connecting column 110. The cylinder 20 is installed on the top surface of the fixed top plate 120, and the extending end of the cylinder 20 passes through the fixed top plate 120 and is connected to the hot-melt member 30.

[0044] An explanation is made that the connecting column 110 is used to connect the fixed top plate 120 and the fixed bottom plate 130 and can be made of high-strength alloy material, thereby ensuring a stable form even in high-temperature or heavy-load environments and effectively preventing equipment failures or safety accidents caused by material deformation. Secondly, a plurality of mounting holes are also provided on the fixed top plate 120 and the fixed bottom plate 130, making the installation process of the cylinder 20 more simple and fast, reducing installation errors, and improving work efficiency.

[0045] In combination with the accompanying drawings of the specification Figures 1-12 As shown, the hot-melt member 30 includes a connecting seat 310, a heat-insulating column 320, and a hot-melt head 330. The connecting seat 310 is arranged at the bottom of the extending end of the cylinder 20. The heat-insulating column 320 is arranged on the bottom surface of the connecting seat 310 and is used to connect the connecting seat 310 and the hot-melt head 330. The hot-melt head 330 includes a head cover 3310, and a heating rod 3320 for heating and a temperature-sensing wire 3330 for detecting temperature are arranged inside the head cover 3310.

[0046] It is explained that the connection between the connecting seat 310 and the extending end of the air cylinder 20 adopts a locking mechanism, ensuring that the connecting seat 310 can be firmly fixed at the bottom of the air cylinder 20 in a high-speed and high-frequency working environment, effectively preventing loosening or falling off problems caused by vibration or impact. Among them, the heat insulation column 320, as a key component connecting the connecting seat 310 and the hot melt head 330, can select high-performance heat insulation materials according to actual situations, thereby effectively blocking the high temperature generated during the operation of the hot melt head 330 from being transmitted to the air cylinder 20 and protecting the internal parts of the air cylinder 20 from damage; at the same time, it also has good mechanical strength and stability, can withstand various mechanical loads during the hot melt process, and ensures the overall structure of the hot melt component 30 is stable.

[0047] Specifically, the hood 3310 adopts a detachable design, which is convenient for users to maintain and replace internal components such as the heating rod 3320 and the temperature sensing wire 3330. The heating rod 3320 arranged inside the hot melt head 330 can quickly and sufficiently provide heat during operation, and can thus rapidly rise to the set temperature within a short time and maintain stability. The temperature sensing wire 3330 closely cooperates with the heating rod 3320, monitors the temperature change inside the hot melt head 330 in real time, and performs signal feedback to ensure that the hot melt head 330 always remains within the optimal working temperature range, thereby improving the quality and efficiency of the hot melt operation.

[0048] Combined with the accompanying drawings of the specification Figures 1-12 As shown, the fixing component 40 includes a fixing seat 410. The fixing seat 410 is installed on the top surface of the fixing base plate 130 through a pair of fixing bolts 70. A fixing groove 420 is formed inside the fixing seat 410. A fixing strip 60 for fixing the supporting component 50 is arranged in the fixing groove 420. The supporting component 50 includes a supporting column 510 and a limiting bolt 540. One end of the limiting bolt 540 is arranged in the installation groove formed in the fixing strip 60, and the other end of the limiting bolt 540 penetrates through the fixing seat 410 and is connected to the bottom of the supporting column 510. The plastic part 80 includes a plastic cover 810. A groove 840 is formed on the inner bottom surface of the plastic cover 810. A pair of clamping columns 850 are arranged inside the groove 840; a top seat 520 is further arranged on the top surface of the supporting column 510. A pair of clamping grooves 530 are formed inside the top seat 520. The plastic cover 810 is fixed on the top of the supporting column 510 through the clamping connection between the clamping columns 850 and the clamping grooves 530.

[0049] It is explained that the fixing seat 410 and the supporting column 510 are made of high-strength alloy materials, ensuring the stability and durability of the overall structure, and being able to withstand large external loads without being easily deformed. At the same time, the good corrosion resistance and wear resistance of the alloy materials also extend the service life of the product.

[0050] Specifically, the fixed seat 410 is firmly mounted on the top surface of the fixed base plate 130 by a pair of fixing bolts 70 to ensure accurate installation position. The fixing strip 60 installed in the fixing groove 420 formed inside the fixed seat 410 prepares for the subsequent installation of the support member 50. By inserting one end of the limit bolt 540 into the installation groove on the fixing strip 60 and connecting the other end to the bottom of the support column 510, and tightening the limit bolt 540 with the support column 510 by rotation, the stable installation of the support member 50 is achieved. Finally, align the clamping post 850 at the bottom of the plastic cover 810 with the clamping groove 530 inside the top seat 520, and gently press to achieve the firm clamping connection between the plastic cover 810 and the support column 510.

[0051] Combined with the accompanying drawings of the specification Figures 1-12 As shown, a boss 820 vertically opposite to the hot melt head 330 is further provided on the top surface of the plastic cover 810. A convex post 830 is provided on the top surface of the boss 820, and at least three convex posts 830 are provided; the fixing member 90 includes a fixing piece 910. Through holes 920 equal in number to the convex posts 830 are formed inside the fixing piece 910. The fixing piece 910 is fixed on the top surface of the boss 820 through the sleeving of the convex posts 830 and the through holes 920.

[0052] An explanation is made that the fixing member 90 and the plastic part 80 are fixedly connected together by the hot melt head 330. When the hot melt head 330 moves down to above the fixing member 90 and touches it, the convex posts 830 provided on the top surface of the plastic part 80 can be melted under the action of high temperature. After the convex posts 830 are melted, their shapes can be changed to fill the through holes 920 formed on the fixing piece 910, and then through cooling and solidification, the fixing member 90 and the plastic part 80 are fixedly connected.

[0053] Specifically, the number of the through holes 920 formed inside the fixing piece 910 corresponds to that of the convex posts 830, enabling the operator to conveniently set the fixing member 90 on the top surface of the plastic part 80 before processing. Through a simple sleeving action, the fixing piece 910 can be firmly locked on the top surface of the boss 820 without additional fasteners or complex installation steps, greatly reducing the installation cost and time cost. In addition, the diameters of the through holes 920 and the convex posts 830 also need to match each other, thus ensuring the tightness of the connection and avoiding the risk of installation difficulties or damage caused by being too tight.

[0054] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
