[0020] In related technologies, straws are a common liquid drinking tool in daily life and have a wide range of applications. As people's requirements for straws increase, a high-efficiency and complete straw manufacturing equipment is needed.

[0021] However, current straw processing relies heavily on multiple decentralized independent workstations or manual semi-automatic operations. This traditional production method has the following drawbacks: First, the processes are poorly coordinated, requiring manual handling and loading / unloading between different machines, resulting in low production efficiency and high labor costs; second, the punching and sealing of straws are mostly in rigid contact, lacking effective guidance, leading to punching misalignment, weak sealing, or poor appearance consistency, resulting in a high defect rate and failing to meet the demands of modern large-scale, high-precision, and multi-variety production.

[0022] The purpose of this application is to overcome the defects and deficiencies in the prior art and provide a straw manufacturing device 1. This straw manufacturing device 1 aims to solve problems such as poor connection between processes and low production efficiency in related technologies. Figure 1 , Figure 2 , Figure 3 and Figure 6 , Figure 1 This is a structural schematic diagram of the straw manufacturing equipment of this application. Figure 2 yes Figure 1 A schematic diagram of the feeding device in the straw manufacturing equipment of the embodiment. Figure 3 yes Figure 1 A schematic diagram of the punching device in the straw manufacturing equipment of the embodiment. Figure 6 yes Figure 1 A schematic diagram of the pressing device in the straw manufacturing equipment of the embodiment includes a feeding device 10, a punching device 11, and a pressing device 12. The feeding device 10 is used to accommodate and feed the initial state raw material of the straw to the downstream device. The punching device 11 is used to open the straw. The pressing device 12 is used to pressurize and flatten the straw. The feeding device 10 includes a feeding conveyor 100, a receiving groove 101, and a separating member 102. The receiving groove 101 is a receiving space for the straw. The feeding conveyor 100 transports the straw to the downstream of the feeding device 10. The separating member 102 is used to separate the straw into individual pieces and transfer them to the feeding conveyor 100. In some embodiments, the receiving groove 101 is used to accommodate the straw and the feeding device. The material transport component 100 and the separating component 102 are accommodating components. The separating component 102 is a component for batch material placement into the tank. The separating component 102 can be, but is not limited to, a vacuum feeding wheel. The separating component 102 integrates a negative pressure vacuum adsorption air path. During operation, the vacuum negative pressure firmly adsorbs the suction tube into the accommodating tank 101, preventing the suction tube from deviating, jumping, or falling out of the accommodating tank 101 during high-speed rotation and conveying. The feeding transport component 100 is a component for pushing the suction tube. In some embodiments, the feeding device 10 also includes a suction tube length adjustment component. The feeding transport component 100 works with the suction tube length adjustment component. After the rear suction tube length adjustment push plate completes the reference positioning, the suction tube is smoothly pushed forward and accurately delivered into the subsequent punching device 11.

[0023] like Figure 1 As shown, the straw manufacturing equipment 1 also includes a timing belt 17, which connects the various devices of the straw manufacturing equipment 1 and drives the straws to be transported. The timing belt 17 is a transmission belt that drives the straws to be transported. The timing belt 17 is provided with a straw receiving groove 101 for accommodating the straws, thereby driving the straws to move between the various devices in various states.

[0024] like Figure 1 , Figure 3 and Figure 4 As shown, Figure 4 yes Figure 3A cross-sectional structural diagram of the punching component of the punching device in the embodiment is shown. The punching device 11 is located downstream of the feeding device 10. The punching device 11 includes a punching transport component 110 and a punching assembly 112. The punching transport component 110 is used to transport the straw, and the punching assembly 112 punches holes in the straw. In some embodiments, the punching device 11 also includes a first straw adjustment component 1125. The punching transport component 110 is provided with an inlet of the synchronous belt 17 and a punching clamping component 111. The straw enters through the inlet of the synchronous belt 17 and is clamped by the punching clamping component 111. The straw is conveyed at a uniform speed by the synchronous belt 17 and directly fed into the punching clamping component 111. After the punching clamping component 111 completes the clamping and fixing, the punching assembly 112 rotates intermittently at equal intervals according to a set rhythm, and sequentially transfers the straw semi-finished product to the processing area. The first straw adjustment component 1125 drives the straw to perform axial locking, fixing the front and rear positions of the straw. Finally, the punching assembly 112 punches holes.

[0025] In some embodiments, the punching assembly 112 includes a fixing member 1120, a punching member 1121, a punching drive member 1122, an elastic member 1123, and a waste discharge member 1124; wherein, the fixing member 1120 is used to fix the straw, the punching drive member 1122 is connected to the punching member 1121, and the punching drive member 1122 is used to drive the punching member 1121 to punch holes in the straw, the punching member 1121 may be, but is not limited to, two sets of punch assemblies arranged symmetrically on the left and right, which are squeezed by the punching drive member 1122 and close towards the center to punch the straw sidewall that passes through the fixing member 1120. The elastic member 1123 is pre-installed inside the punch assembly, and the punch automatically retracts to release the material during the mold opening return stroke; the waste discharge member 1124 is connected to the fixing member 1120, and the fixing member 1120 has a through hole facing the internal channel of the straw; wherein, the waste is extracted from the internal channel by external negative pressure vacuum suction.

[0026] The punching device 11 includes a first punching assembly 113 and a second punching assembly 114. The first punching assembly 113 includes a first punching component 1130 and a first punching transport component 1131. The second punching assembly 114 includes a second punching component 1140 and a second punching transport component 1141. The first punching component 1130 has a first through-hole group 1132 on the straw. The synchronous belt 17 drives the straw to be transported from the first punching component 1130 to the second punching component 1140. The second punching component 1140 has a second through-hole group 1142 on the straw. In some embodiments, the first punching assembly 113 and the second punching assembly 114 have basically the same structure, so they will not be described in detail here. The straw is punched by the first punching part 1130 and then transferred to the second punching part 1140 by the synchronous belt 17. After being processed by the second punching part 1140, the straw continues to rotate with the second punching transport part 1141 and flows to the subsequent unloading process. After the first punching transport part 1131 and the punching clamping part 111 of the second punching transport part 1141 transfer the straw, they will turn back to the feeding end to receive the next batch of semi-finished straws, and the cycle continues.

[0027] The first through-hole group 1132 consists of two through-holes on the straw, located on opposite sides. The second through-hole group 1142 consists of two more through-holes on the straw, located on sides different from the first through-hole group 1132. In this application, the first through-hole group 1132 is punched out by the first punching part 1130. The two through-holes are located on opposite sides of the straw. In some embodiments, the liquid outlet of the straw includes four connected surfaces, with the first through-hole group 1132 located on two opposite surfaces and the second through-hole group 1142 located on the other two opposite surfaces, thus forming four liquid outlets on the straw. This allows the straw produced in this application to be geometrically constrained and deflected and dispersed when liquid flows out, thereby changing the flow state of a single jet and forming a diffused liquid flow. It also has multiple liquid outlets, enriching the taste.

[0028] like Figure 1 , Figure 3 and Figure 5 As shown, Figure 5 yes Figure 1The schematic diagram of the heating device in the straw manufacturing equipment of the embodiment is shown. The straw manufacturing equipment 1 includes a heating device 13, which is located downstream of the punching device 11 and upstream of the pressing device 12. The heating device 13 is equipped with a heating component 130, which is used to heat and soften the straw. In some embodiments, the heating component 130 may be, but is not limited to, a U-shaped integrated copper tank. Copper material has uniform heat conduction and stable heat storage. The inside of the tank is a straw passage. The tank is divided into independent multi-segment temperature control zones along the material travel path. Each segment is equipped with an independent heating module and temperature sensing unit, which supports independent setting of heating temperature for each segment. The heating parameters of each segment can be set differently according to the straw material, wall thickness, and pressing process requirements to accurately control the degree of softening of the straw wall and ensure the subsequent pressing and bonding strength.

[0029] like Figure 1 , Figure 6 and Figure 7 As shown, Figure 6 yes Figure 1 A schematic diagram of the pressing device in the straw manufacturing equipment of the embodiment. Figure 7 yes Figure 5 A cross-sectional structural diagram of the pressing component in the pressing device of the embodiment; the pressing device 12 is located downstream of the punching device 11. The pressing device 12 includes a pressing assembly 120 and a pressing transport component 121. The pressing transport component 121 is used to transport the straw, and the pressing assembly 120 presses and seals the straw. In some embodiments, the pressing assembly 120 includes a pressing component 1202 and a second straw adjustment component 1205, wherein the pressing component 1202 is used to press the end opening of the straw, and the second straw adjustment component 1205 is used to adjust the position of the straw on the pressing component 1202, thereby adapting to straws of different sizes; the pressing transport component 121 also includes a pressing straw clamping component 1204. The pressing transport component 121 is provided with a pressing inlet and a pressing outlet. The synchronous belt 17 transports the straw semi-finished product from the pressing inlet to the pressing component 1202. After pressing, it is output to the next process through the pressing component 1202.

[0030] In some embodiments, the suction tube conveyed by the synchronous belt 17 in the current process is fed into the pressing suction tube clamping member 1204 of the pressing transport member 121 from the length adjustment position. The second suction tube adjusting member 1205 sets the axial stop point according to the current product specifications, accurately pushes the end of the suction tube to the pressing reference position, and locks the axial position at the same time to prevent the tube from moving back and forth during processing, ensuring that the pressing point of the single end is consistent. The pressing transport member 121 rotates equally according to a fixed rhythm. The station for loading the suction tube starts from the feed port. The pressing transport member 121 is relatively large, thus reserving sufficient time for pressurization and constant temperature shaping of the single end. When the suction tube rotates with the pressing transport member 121 to the suction tube pressing open station, each set of pressing suction tube clamping members 1204 opens synchronously, releasing the clamping of the suction tube. Once formed, the single-sided sealed straw rotates out of the turntable from this position and flows to the subsequent process; after unloading, the empty pressing straw clamp 1204 continues to rotate and returns to the pressing feed port.

[0031] The pressing assembly 120 includes a straw return component 1200, a pressing component 1202, and a pressing drive component 1201. The straw return component 1200 is used to adjust the straw to the central reference axis of the pressing component 1202. In some embodiments, it serves as a pre-positioning return component before pressing, receiving the softened straw delivered from the front copper heating tank. Before the pressing action is initiated, the limiting structure corrects any offset or skewed straw to the central reference axis, ensuring that the straw end face is completely centered and aligned with the pressing working surface. The pressing component 120... 2 can be, but is not limited to, upper and lower temperature-controlled pressing components. The upper and lower temperature-controlled pressing components maintain a set process temperature and perform secondary constant-temperature pressure pressing on the softened end face of the straw. Utilizing heat and external pressure, the straw end face and tube wall are tightly welded together, completing the end face sealing. A pressing elastic component 1203 is also provided between the pressing drive component 1201 and the pressing component 1202. The pressing drive component 1201 can drive the pressing component 1202 to press, and the pressing elastic component 1203 is used to precisely control the pressing contact pressure. After the pressing component 1202 and the pressing drive component 1201 complete their closing stroke, a spring provides flexible buffering clamping force. By replacing springs with different stiffnesses or adjusting the pre-compression amount, the end face pressing pressure can be flexibly adjusted to seal and press the straw.

[0032] like Figure 1 , Figure 8 and Figure 9 As shown, Figure 8 yes Figure 1 A schematic diagram of the cutting device in the straw manufacturing equipment of the embodiment. Figure 9 yes Figure 8A cross-sectional view of the cutting component in the cutting device of the embodiment; the straw manufacturing equipment 1 also includes a cutting device 14, which is located downstream of the pressing device 12. The cutting device 14 is used to cut the straw and to trim and shape the excess end face of the straw; in some embodiments, the cutting device 14 includes a cutting component 140 and a cutting transport component 1404. The synchronous belt 17 transports the semi-finished straw to the cutting transport component 1404. The cutting component 140 includes a cutting fixing component 1400, a cutting component 1401, a cutting elastic component 1402, a cutting drive component 1403, and a waste discharge component 1124; wherein, the cutting fixing component 1400 is a pre-cutting positioning component. The straw to be trimmed first passes through the cutting component 1401. Before the cutting action is started, the cutting component 1400... The cutting component 1401 first gathers and centers the straw, constraining the tube on the central reference axis. The cutting component 1401 can be, but is not limited to, upper and lower cutters. The cutting drive component 1403 drives the cutting component 1401 to move up and down, thereby trimming the straw. The cutting drive component 1403 can be, but is not limited to, a cam drive wheel and a cam slide. The cam drive wheel and the cam slide are connected. The cutting drive component 1403 is used to convert the vertical drive stroke into a horizontal thrust, which is used to drive the cam slide forward. The cam slide is also connected to the upper and lower cutting components 1401. Driven by the cam follower, it moves forward horizontally. Relying on its own inclined structure, it decomposes the horizontal thrust into a clamping and cutting force in both directions, causing the upper and lower cutting components 1401 to close synchronously in opposite directions.

[0033] like Figure 1 and Figure 10 As shown, Figure 10 yes Figure 1 The schematic diagram of the rotating device in the straw manufacturing equipment of the embodiment shows that the straw manufacturing equipment 1 also includes a rotating device 15, which is located downstream of the cutting device 14. The rotating device 15 is used to rotate the straw to a preset angle. In some embodiments, the rotating device 15 includes a rotating component 150 and a rotating transmission component 151. The front end of the rotating component 150 is provided with a clamping station adapted to the shape of the flat end of the straw. The flat end of the straw to be processed is inserted into the internal positioning slot, and it can rotate and swing along the axis. The rotation action changes the spatial orientation of the flat end, thereby meeting the different requirements of different customers for the installation angle and usage angle of the flat end. The rotating transmission component 151 is used to carry the rotated straw to the next process.

[0034] like Figure 1 and Figure 11 As shown, Figure 11 yes Figure 1The embodiment shows a schematic diagram of the bending and discharging device in the straw manufacturing equipment. The straw manufacturing equipment 1 also includes a bending and discharging device 16, which is located downstream of the rotating device 15. The bending and discharging device 16 includes a bending component 160 and a discharging component 161. The bending component 160 is used to bend the liquid outlet end of the straw, and the discharging component 161 is used to push out the assembled straw. The bending assembly 160 includes a bending guide groove 1600 and a bending drive component 1601. The bending drive component 1601 is used to drive the straw to the bending guide groove 1600. Under the external force of the bending drive component 1601, the straw bends along the bending guide groove 1600. In some embodiments, the bending guide groove 1600 is a U-shaped guide groove. When the straw enters the bending guide groove 1600, it enters the bending groove path under the constraint of the guide structure. Under the action of external force and the limiting action of the groove body, it bends according to a fixed arc and finally forms a standard U-shaped shape. The discharge assembly 161 includes a U-shaped discharge port. The finished straw comes out from this position and waits for the hook mechanism of the back-end packaging machine to grab and pick up the material and send it into the subsequent packaging process.
