[0025] In one embodiment of this utility model, such as Figures 1-4As shown, a rubber dispensing cylinder is provided, including a dispensing cylinder 1 and a dispensing needle 2, with the dispensing needle 2 fixedly connected to the bottom of the dispensing cylinder 1. A heating cylinder 3 is fixedly sleeved on the outside of the dispensing cylinder 1, and a first heating chamber 31 is formed on the inside of the heating cylinder 3, with the dispensing cylinder 1 disposed within the first heating chamber 31. A heating head 4 is provided on the outside of the dispensing needle 2, and the heating head 4 is located on the outside of the dispensing cylinder 1 and fixedly connected to the heating cylinder 3. A second heating chamber is formed on the inside of the heating head 4, with the dispensing needle 2 disposed within the second heating chamber. The heating cylinder 3 and the heating head 4 cover the dispensing cylinder 1 and heat it. Furthermore, the heating cylinder 3 and the heating head 4 are made of copper, which provides better heating and heat conduction. A temperature sensor can be connected to the heating cylinder 3 and the heating head 4 to sense the temperature, and a temperature display can be connected to the temperature sensor to display the temperature inside the heating cylinder 3 and the heating head 4 in real time, facilitating real-time temperature monitoring. A heat-insulating cylinder 5 is provided on the outside of the heating cylinder 3 and the heating head 4. A heat-insulating cavity 51 is formed inside the heat-insulating cylinder 5.

Furthermore, the heat-insulating cylinder 5 is made of plastic steel. The heating cylinder 3 and the heating head 4 simultaneously heat the dispensing cylinder 1, increasing the heating area of ​​the dispensing cylinder 1, improving heating efficiency, and the heat-insulating cylinder 5 further delays heat dissipation, thus enhancing the heating effect.

[0026] In another embodiment of this utility model, one end of the dispensing needle 2 of the rubber dispensing tube is disposed inside the heating head 4, and the other end extends out of the heating head 4, for dispensing the product.

[0027] In another embodiment of this utility model, the dispensing tube 1 of the rubber dispensing tube is provided with a tube cap 6 at the end away from the dispensing needle 2. The tube cap 6 is inserted into the dispensing tube 1 and fixes the dispensing tube 1.

[0028] In another embodiment of this utility model, the top side of the rubber dispensing cylinder cap 6 is provided with a heat-insulating sleeve 7, which is installed on the heat-insulating cylinder 5. After the heat-insulating sleeve 7 is installed on the heat-insulating cylinder 5, it has a heat-insulating effect, delays the heat loss of the heat-insulating cylinder 5, and improves the heating effect of the material inside the dispensing cylinder 1.

[0029] In another embodiment of this utility model, the insulating sleeve 7 of the rubber dispensing cylinder is provided with two fixing bolts 8.

The fixing plate 9 facilitates fixing and positioning, making it convenient to fix and position the rubber dispensing cylinder provided in this application.

[0031] The rubber dispensing cylinder provided in this application is used as follows: The insulation cylinder 5 and the overall structure are fixed by the fixing plate 9. Since the head of the fixing bolt 8 is provided with anti-slip teeth, it is easy to tighten and loosen by hand, making the operation more convenient and quick. After loosening and removing the fixing bolt 8, the insulation cover 7 is removed. After removing the insulation cover 7, the rubber cylinder cover 6 is removed. Then, the material is put into the dispensing cylinder 1, and the rubber cylinder cover 6 is placed on the dispensing cylinder 1. The insulation cover is placed on the insulation cylinder 5, and then the insulation cover is fixedly connected to the insulation cylinder 5 by the fixing bolt 8. The heating cylinder 3 and the heating head 4 heat the material in the dispensing cylinder 1 at the same time, which increases the heating area and improves the heating efficiency. Under the continuous heating of the heating cylinder 3 and the heating head 4, the temperature in the dispensing cylinder 1 continues to rise until it reaches the melting point of the material in the dispensing cylinder 1. The material begins to melt and form a molten state and a fluid. The fluid material is squeezed out through the dispensing needle 2 and the product is dispensed.

[0032] The rubber dispensing cylinder provided in this application heats the dispensing cylinder 1 simultaneously through the heating cylinder 3 and the heating head 4, thereby increasing the heating area, making the dispensing cylinder 1 heat more evenly, and improving the heating efficiency.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
