Description

Technical Field

[0001] This utility model relates to the technical field of disposable straw processing equipment, and more specifically, to a bending device for disposable straws made of modified biodegradable materials. Background Technology

[0002] Modified biodegradable materials are environmentally friendly, as they can be decomposed by microorganisms in the natural environment and eventually converted into carbon dioxide, water, and inorganic salts, reducing white pollution and soil burden. They are also easy to optimize in terms of performance. Through copolymerization, blending, or molecular modification, the materials can improve hydrophilicity, mechanical strength, and heat resistance, and have been widely used in the processing and production of daily necessities such as food bags and straws.

[0003] For disposable straws made from modified biodegradable materials, in the post-forming and cutting process, some disposable straws require an additional bending process depending on customer needs. This involves processing multi-layered embossing on the upper part of the straw to facilitate stretching and adjustment during use. Existing bending equipment only uses a single bending rod with a pressure ridge to continuously bend the disposable straw supported by a bracket. In practical use, this has the following problems: firstly, the bending efficiency is low, only one straw can be bent per unit time; secondly, the bending effect is not good enough, as the bending rod only acts on the upper side plate of the straw and the bending is rotational, making the straw prone to jumping and displacement. Utility Model Content

[0004] The purpose of this invention is to provide a bending device for disposable straws made of modified biodegradable materials. This device uses a pressing head with bending ribs and a pressing groove with bending grooves to bend straws by pressing down. It can bend multiple disposable straws per unit time with high efficiency. At the same time, it can bend both the upper and lower sides of the disposable straw, resulting in a better bending effect.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A modified biodegradable disposable straw bending device includes a base, a control box at the front of the upper surface of the base, and a rotating shaft driven by a drive motor mounted on the upper surface of the base via a bracket. A top conveyor belt and a bottom conveyor belt are mounted on the rotating shaft, with the bottom conveyor belt being wider than the top conveyor belt. Both the top and bottom conveyor belts have several equidistantly spaced locking blocks on their outer surfaces. A disposable straw is embedded between adjacent locking blocks. The area of ​​the disposable straw to be bent is located in the hollow space between the top and bottom conveyor belts, and a bending device is provided in the hollow space between the top and bottom conveyor belts.

[0007] As a further optimization of this solution, the bending device includes an L-shaped connecting plate. The lower end of the vertical section of the L-shaped connecting plate is fixed to the upper surface of the base, and a controller is provided on the upper surface of the horizontal section of the L-shaped connecting plate. Several telescopic electric cylinders are fixed at equal intervals on the lower surface of the controller by screws. The piston rods of the several telescopic electric cylinders are all connected downward to the upper surface of the pressure head. Several bending ribs are processed at equal intervals on the arc-shaped lower surface of the pressure head. The controller is connected to the control box through a circuit, and the control box is connected to an external power supply.

[0008] As a further optimization of this solution, a pressure groove is provided below the pressure head, and several bending grooves are processed at equal intervals on the arc surface inside the pressure groove. The several bending ribs are aligned and pressed down into the internal area of ​​the bending groove. The lower surface of the pressure groove is connected to the upper surface of the base through several telescopic connecting rods. The upper end surface of the pressure groove does not exceed the height of the lowest point of the locking block.

[0009] As a further optimization of this solution, baffles are provided on the front and rear outer sides of the top and bottom conveyor belts. The baffles are spaced three to five centimeters apart from the top and bottom conveyor belts, and the baffles are connected to the upper surface of the platform through L-shaped support plates spaced apart on the outer side.

[0010] As a further optimization of this solution, the upper surface of the platform is also equipped with a discharge conveyor belt via a bracket.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0012] This invention utilizes a top and bottom conveyor belt structure with a hollow central area, combined with a pressure head featuring bent ribs and a pressure groove structure with bending grooves. This allows for simultaneous bending of multiple disposable straws, resulting in better processing consistency and higher bending efficiency. By replacing traditional bending rods with a downward bending method, the pressure surface coverage area is more comprehensive, enabling bending operations on both the upper and lower outer sides of the disposable straws. This leads to better bending results and prevents the disposable straws from jumping or shifting. Attached Figure Description

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0019] To address the issues of low bending efficiency, the inability to bend only one disposable straw per unit time, poor bending effect, and the fact that the bending rod can only act on the upper half of the disposable straw and is a rotating bending method, which makes the disposable straw prone to jumping and displacement.

[0020] like Figure 1 As shown, this application includes a base 1, a control box 2 is provided at the front of the upper surface of the base 1, and a rotating shaft driven by a drive motor 18 is mounted on the upper surface of the base 1 via a bracket 3. A top conveyor belt 4 and a bottom conveyor belt 5 are mounted on the rotating shaft. The width of the bottom conveyor belt 5 is greater than the width of the top conveyor belt 4. A number of circumferentially distributed locking blocks 6 are processed on the outer sides of both the top conveyor belt 4 and the bottom conveyor belt 5. A disposable straw 7 is embedded in the area between adjacent locking blocks 6. The area to be bent of the disposable straw 7 is located in the hollow position between the top conveyor belt 4 and the bottom conveyor belt 5. A bending device is provided in the hollow position between the top conveyor belt 4 and the bottom conveyor belt 5.

[0021] like Figure 2 As shown, the bending device includes an L-shaped connecting plate 8. The lower end of the vertical section of the L-shaped connecting plate 8 is fixed to the upper surface of the base 1, and a controller 9 is provided on the upper surface of the horizontal section of the L-shaped connecting plate 8. Several telescopic electric cylinders 13 are fixed at equal intervals on the lower surface of the controller 9 by screws. The piston rods of the several telescopic electric cylinders 13 are all connected downward to the upper surface of the pressure head 14.

[0022] like Figure 4 As shown, the lower surface of the pressure head 14 is arc-shaped and has several bent ribs 19 processed at equal intervals. The controller 9 is connected to the control box 2 through a line, and the control box 2 is connected to an external power supply.

[0023] like Figure 3As shown, a pressure groove 16 is provided below the pressure head 14. Several bending grooves 17 are processed at equal intervals on the arc surface inside the pressure groove 16. Several bending ribs 19 are aligned and pressed down to the area above the bending grooves 17. The lower surface of the pressure groove 16 is connected to the upper surface of the base 1 through several telescopic connecting rods 15. The upper end surface of the pressure groove 16 does not exceed the height of the lowest point of the locking block 6.

[0024] like Figure 1 As shown, baffles 12 are provided on the front and rear outer sides of the top conveyor belt 4 and the bottom conveyor belt 5. The baffles 12 are spaced three to five centimeters apart from the top conveyor belt 4 and the bottom conveyor belt 5. The baffles 12 are connected to the upper surface of the platform 1 through L-shaped bracket plates 11 spaced on the outer side. The upper surface of the platform 1 is also supported by a discharge conveyor belt 10 through a bracket 3.

[0025] Specifically, multiple disposable straws 7 are transported sequentially by the feeding conveyor belt into the internal limit blocks 6 adjacent to the top conveyor belt 4 and the bottom conveyor belt 5. When the multiple disposable straws 7 are transported by the top conveyor belt 4 and the bottom conveyor belt 5 to the area between the pressing head 14 and the pressing groove 16, the drive motor 18 stops working. The controller 9 can control all the telescopic electric cylinders 13 to work, and the piston rod presses down the pressing head 14 into the internal area of ​​the pressing groove 16 to perform a one-time bending operation on the area to be bent of the multiple disposable straws 7. After the operation is completed, the telescopic electric cylinder 13 continues to lift the pressing head 14, and the drive motor 18 is restarted to drive the bent multiple disposable straws 7 to fall onto the discharge conveyor belt 10 and continue to be transported to the packaging process. The installation height of the pressing groove 16 can be adjusted by the telescopic connecting rod 15, but the upper end of the pressing groove 16 does not exceed the height of the lowest point of the block 6 so that the multiple disposable straws 7 can smoothly enter the bending area. The baffle 12 is used to prevent the internal disposable straws 7 from falling onto the waiting table 1.
