[0002] Biodegradable straws are an environmentally friendly alternative to traditional plastic straws, reducing environmental pollution. With increasing global concern about plastic waste, biodegradable straws have become a popular product in the market. Most biodegradable straws are produced using automated straw forming machines, with different forming rod assemblies required for different straw models. These forming rod assemblies are detachable and installed onto the forming part of the straw forming machine. The ease of installation of these assemblies determines the efficiency of replacement during production, which in turn determines the efficiency of straw model switching, resulting in differences in overall production efficiency and affecting the use of straws in production. Straw forming rod assemblies that cannot be quickly replaced will affect straw production efficiency and increase the labor intensity of operators, which is detrimental to the actual use of straws.

[0003] In summary, the straw forming rod assembly without a quick-change structure has some problems in use. Therefore, it is hoped that a new structure can be proposed to solve the above-mentioned technical problems. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figures 1 to 7 This utility model provides a technical solution: a straw forming rod assembly with a quick replacement structure, including: a forming rod inner core 100, a blocking assembly 105 and an upper outer ring assembly 108, and a set of inlet posts 101 for introducing cooling water are fixedly connected to the left end of the outer side of the forming rod inner core 100.

[0026] A set of outlet columns 102 for discharging cooling water is fixedly connected to the right end of the outer side of the inner core 100 of the forming rod. A set of plugging components 105 for blocking the inlet and outlet after disassembly to prevent internal water from overflowing is installed on the inner side of both the inlet column 101 and the outlet column 102.

[0027] Both the inner side of the inlet post 101 and the outlet post 102, away from the center of the inner core 100 of the forming rod, are equipped with a set of quick connectors 107 by heat fusion connection. An upper outer ring assembly 108 is provided above the outer side of the inner core 100 of the forming rod, and an upper and lower outer ring assembly 109 is provided below the outer side of the inner core 100 of the forming rod.

[0028] The upper outer ring assembly 108 and the lower outer ring assembly 109 are each fixedly connected to a set of connectors at the same position as the inlet post 101 and the outlet post 102. A set of quick connectors 113 are also installed at the end of the connectors near the inner core 100 of the forming rod by heat fusion connection.

[0029] Quick connector 107 and quick connector 213 are used together for connection. Quick connector 213 has a guide post 114 on its inner side for guiding the blockage component 105. The inner side of the forming rod core 100 has a cooling groove 106 for cooling. When the upper outer ring component 108 and the lower outer ring component 109 are connected to the forming rod core 100, quick connector 107 and quick connector 213 are quickly connected to achieve quick installation.

[0030] The cooling tank 106 has a spiral structure. The blocking component 105 has a lower support seat 105a at one end near the center of the inner core 100 of the forming rod. A blocking spring 105c is fixedly connected to the end of the lower support seat 105a away from the center of the inner core 100 of the forming rod.

A blocking seat 105e is provided at one end of the blocking ball 105d away from the center of the inner core 100 of the forming rod. A sealing square groove 105f for fitting and sealing with the blocking ball 105d is opened at the center of the blocking seat 105e. When quick connector 107 and quick connector 2 113 are connected, the guide post 114 drives the blocking ball 105d to move, so that the blocking ball 105d is disengaged from the sealing square groove 105f, realizing pipeline conduction. After disassembly, the blocking spring 105c drives the blocking ball 105d to achieve blockage and sealing.

[0032] Both the upper outer ring assembly 108 and the lower outer ring assembly 109 have a sealing groove 110 on one side near the center of the inner core 100 of the forming rod.

Second, when quick connector one 107 and quick connector two 113 are connected, the guide post 114 drives the blocking ball 105d to move, causing the blocking ball 105d to disengage from the sealing square groove 105f, thereby realizing the pipe connection. After disassembly, the blocking spring 105c drives the blocking ball 105d to achieve blockage and sealing, preventing the internal cooling water from spilling when the inner core 100 of the forming rod is disassembled. It also allows external cooling water to be introduced into the cooling tank 106 through the inlet column 101 and discharged through the outlet column 102. The spiral structure of the cooling tank 106 can improve the cooling effect after the suction tube is formed, and the leaked cooling water overflows into the receiving tank 111 and is detected by the detection probe 112, preventing the problem of pipeline leakage that cannot be detected for a long time, thereby achieving the effect of quick replacement.

[0034] A set of mounting ring seats 103 is fixedly connected to the inner side of the inlet post 101 and the outlet post 102 near the center of the inner core 100 of the forming rod. A mounting ring groove 104 is opened at the inner side of the inlet post 101 and the outlet post 102 away from the center of the inner core 100 of the forming rod.

[0035] The lower support 105a and the plug 105e are both provided with mounting threaded holes 105b on their outer surfaces. The lower support 105a fits into the mounting ring 103, and the plug 105e fits into the mounting ring groove 104.
