[0015] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0016] See also Figure 1 , the utility model embodiment includes:

[0017] A paper tube continuous drying production line, the paper tube continuous drying production line comprises: an oven, an oven bracket 1, a paper tube conveying mechanism and a receiving basket 21, the oven is installed on the oven bracket 1, the oven has a feed door and a discharge door at both ends, a feed section, a drying section and a discharge section are continuously arranged between the feed door and the discharge door; the feed section is divided into a feed chamber 5 and a preheating chamber 6, the drying section is divided into two heating chambers 7, the discharge section is divided into a transition chamber 8 and a discharge chamber 9, and each heating chamber 7 is provided with a pair of hot air dryers 11 respectively installed on the upper and lower sides of the conveyor belt 4. The paper tube conveying mechanism includes a conveying frame 2, a paper tube conveyor belt 4 and a conveying roller 3. The conveyor belt 4 is a hollow conveyor belt. The conveying frame 2 is rectangular. The conveying frame 2 is installed in the oven. The two ends pass through the feed door and the discharge door respectively and are fixed on the oven bracket 1. There are 5 conveying rollers 3, which are installed in parallel in the conveying frame 2. The paper tube conveyor belt 4 is sleeved on the conveying roller 3. The paper tube placement position is evenly set on the paper tube conveyor belt 4. Through this structure, when the paper tube is placed in the paper tube placement position for baking, the hot air dryer 11 can blow hot air from both the upper and lower directions at the same time. The hot air impacts each other in the oven to form turbulence, so that the paper tube can be evenly heated from top to bottom and inside and outside, thereby improving the baking effect. The receiving basket 12 is installed just below the discharge end of the paper tube conveyor belt 4. When the paper tube goes out from the discharge end, it will fall directly into the receiving basket 12 from the end under the action of gravity.

[0018] The top of the preheating chamber 6 is connected to the top of the heating chamber 7 at the front end through a first circulation pipe, a first circulation fan 13 is installed in the middle of the first circulation pipe, the bottom of the preheating chamber 6 is connected to the bottom of the heating chamber 7 at the front end through a second circulation pipe, a second circulation fan 14 is installed in the middle of the second circulation pipe, the top of the transition chamber 8 is connected to the top of the heating chamber 7 at the rear end through a third circulation pipe, a third circulation fan 15 is installed on the third circulation pipe, the bottom of the transition chamber 8 is connected to the bottom of the heating chamber 7 at the rear end through a fourth circulation pipe, a fourth circulation fan 16 is installed on the fourth circulation pipe, the first circulation fan 13 and the second circulation fan 14 have the same suction direction, and the third circulation fan 15 and the fourth circulation fan 16 have the same suction direction. Through this air curtain closure method, during the baking process, the preheating chamber 6 and the transition chamber 8 can reduce the temperature gradient when the paper tube enters and exits the furnace, eliminate the influence of rapid temperature changes on the strength of the paper tube, and reduce the loss rate of hot air, reduce energy consumption during baking, and improve overall economic benefits.

[0019] Two groups of conveying frame brackets 10 are symmetrically installed on the inner walls on both sides of the oven. This can prevent the conveying frame 2 from being overstressed and deformed.

[0020] A first telescopic cylinder 17 is installed above the feed door, and a first L-shaped baffle 19 is installed at the end of the telescopic rod of the first telescopic cylinder 17. A second telescopic cylinder 18 is installed above the discharge door, and a second L-shaped baffle 20 is installed at the end of the telescopic rod of the second telescopic cylinder 18. In this way, the shielding range of the two baffles on the feed door and the discharge door can be adjusted according to the diameter of the paper tube in actual use, effectively reducing the heat loss rate.

[0021] When this embodiment is actually used, the residence time of the paper tube in the oven can be controlled by adjusting the baking temperature and the conveying speed of the conveyor belt 4 in different environments in summer and winter, so that the paper tube can be fully baked and the moisture content in the paper tube can meet the process requirements.

[0022] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
