Abstract
Description
Technical Field
[0001] This application relates to the field of straw processing technology, and in particular to a cooling device for producing biodegradable straws. Background Technology
[0002] The general molding process for biodegradable straws involves melting plastic granules, extruding the plastic through a molding device to form a hollow cylinder, cooling it in a cold water tank, and then passing it through a quick-drying device to remove water adhering to the straw's surface. Finally, it is transported by a straw delivery machine to a cutting mechanism for cutting to a preset length. This process is continuous. However, existing cold water tanks have a fixed overflow height and the overflow rate is difficult to adjust. Therefore, the inventors have proposed a cooling device for the production of biodegradable straws. Utility Model Content
[0003] This application provides a cooling device for producing biodegradable straws, which can adjust the overflow height and overflow speed.
[0004] The technical solution of this application is as follows:
[0005] This application provides a cooling device for producing biodegradable straws, which includes a connecting pipe screwed into a water outlet pipe of a cooling tank. The top of the connecting pipe has a joint with an increased inner diameter. A plug is screwed into the joint. The outer wall of the plug is provided with a water groove. The plug can be screwed into the joint to seal the connecting pipe.
[0006] Using the technical solution of this application, the height of the connector changes with the rotation of the connecting pipe, which facilitates the adjustment of the overflow height. The rotation of the plug inside the connector can change the size of the water storage space between the plug and the connecting pipe, which facilitates the adjustment of the overflow speed.
[0007] In some implementations, the axis of the connecting pipe is perpendicular to the liquid level in the cooling tank.
[0008] In some implementations, the connector and the connecting pipe are arranged coaxially.
[0009] In some implementations, the inner diameter of the connector is larger than the outer diameter of the connecting pipe.
[0010] In some implementations, the connector and the connecting pipe are integrated into one structure.
[0011] In some implementations, the extension direction of the water tank is parallel to the axis of the plug.
[0012] In some implementations, the water troughs are evenly distributed around the circumference of the plug.
[0013] In some implementations, the water tank is arranged radially along the plug.
[0014] In some implementations, the water trough runs through both the upper and lower ends of the plug.
[0015] In some implementations, the water tank is located radially outside the connecting pipe. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description of this application is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining this application and are not intended to limit this application.
[0024] In related technologies, the molding process for biodegradable straws generally involves melting plastic granules, extruding the plastic through a molding device to form a hollow cylinder, cooling it in a cold water tank, removing water from the straw surface with a quick-drying device, and then conveying it to a cutting mechanism by a straw delivery machine for cutting to a preset length. This process is continuous. However, the overflow height of existing cold water tanks is fixed, and the overflow speed is difficult to adjust.
[0025] This embodiment provides a cooling device for producing biodegradable straws, which can adjust the overflow height and overflow speed.
[0026] Please see Figures 1-2 In this embodiment, a cooling device for producing biodegradable straws includes a connecting pipe 20 screwed into a water outlet pipe 11 of a cooling tank 10. The top of the connecting pipe 20 has a connector 21 with an increased inner diameter. A plug 30 is screwed into the connector 21. The outer wall of the plug 30 is provided with a water groove 31. The plug 30 can be screwed into the connector 21 to seal the connecting pipe 20.
[0027] Using the technical solution of this embodiment, the height of the connector 21 changes with the rotation of the connecting pipe 20, which facilitates the adjustment of the overflow height. The plug 30 can rotate inside the connector 21 to change the size of the water storage space between the plug 30 and the connecting pipe 20, which facilitates the change of the overflow speed.
[0028] In this embodiment, the cooling tank 10 is constructed as a rectangular box. An inlet pipe and an outlet pipe 11 are provided at the bottom of the cooling tank 10, and the tops of the inlet pipe and the outlet pipe 11 are flush with the bottom surface of the cooling tank 10. Cooling water flows into the cooling tank 10 through the inlet pipe and flows out through the outlet pipe 11, forming a circulation.
[0029] In addition, the lower end of the connecting pipe 20 is screwed into the top opening of the connecting pipe 11. The connecting pipe 20 is kept vertically arranged inside the cooling tank 10. The axis of the connecting pipe 20 is perpendicular to the liquid surface in the cooling tank 10. The top of the connecting pipe 20 is integrally formed with a connector 21, and the connector 21 is constructed as a cylindrical shape arranged coaxially with the connecting pipe 20. The inner diameter of the connector 21 is larger than the outer diameter of the connecting pipe 20. The connector 21 rotates synchronously with the connecting pipe 20.
[0030] Furthermore, the plug 30 is constructed as a solid cylinder and is screwed into the interior of the connector 21. The water groove 31 is formed on the circumferential surface of the plug 30 and extends through the upper and lower end faces of the plug 30. For example, the extension direction of the water groove 31 is parallel to the axis of the plug 30. The water groove 31 is evenly distributed along the circumference of the plug 30 and arranged along the radial direction of the plug 30.
[0031] It should be noted that the water tank 31 is arranged on the outside of the connecting pipe 20. That is, the end of the water tank 31 near the axis of the plug 30 is located on the outside of the outer wall of the connecting pipe 20, so that after the plug 30 contacts the connecting pipe 20, the central cylindrical part of the plug 30 can seal the top opening of the connecting pipe 20. At this time, the water in the cooling tank 10 cannot be discharged through the outlet pipe 11.
[0032] It should be understood that when the liquid level inside the cooling tank 10 is higher than the connector 21, water will flow into the connecting pipe 20 through the water tank 31 and finally flow out through the outlet pipe 11. It can be seen that the height of the connector 21 can change the overflow height. When the plug 30 is screwed into the connector 21, the distance between the top surface of the plug 30 and the connecting pipe 20 is reduced, the amount of water flowing into the connecting pipe 20 will decrease, that is, the flow rate of the outlet pipe 11 will decrease, thereby reducing the overflow speed.
[0033] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
