The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0049] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises", or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.

[0050] As described in the background technology, currently straws are usually packaged in the form of straw strips after production, so that multiple compartments containing straws are connected into a strip (and there is a tear line between two adjacent compartments). When the straws leave the factory, each compartment sometimes needs to be cut, but currently it is mainly done manually, which is inefficient.

[0051] Embodiment 1:

[0052] Therefore, in order to solve the above technical problems of the prior art, this embodiment provides a high-speed pipe cutting device, such as Figure 1As shown, the high-speed pipe cutting device includes a pipe cutting assembly 200, which can cut the straw band at equal intervals. The pipe cutting assembly 200 includes:

[0053] A second power unit 210;

[0054] The second hose reel 230 is driven to rotate along its own circumference by the second power device, and an arc groove capable of partially accommodating the straw is provided on the outer surface of the second hose reel 230, and the arc groove extends along the axis direction of the second hose reel, and the arc groove is provided in an array, and the arc grooves in the array are arranged at equal angles along the circumference of the second hose reel 230; and,

[0055] The cutting blade 250 is driven to reciprocate by the second power device 210 to cut the straw band driven by the second tube reel.

[0056] The utility model passes the straw belt through the second pipe reel so that the straw is stuck in the circular arc groove of the second pipe reel, and the second power device drives the second pipe reel to rotate, so as to drive the straw belt to move along the rotation direction of the second pipe reel. At the same time, the cutting blade reciprocates under the drive of the second power device, and the cutting blade cuts once every time the second pipe reel rotates through the angle of the circular arc groove, thereby realizing automatic cutting of the straw belt, dividing the straw belt into individual straws, and improving work efficiency.

[0057] In this embodiment, if Figure 2 As shown, the cutting blade is fixed on a mounting plate 260, and the mounting plate 260 is connected to the eccentric cam through a connecting rod. The second power device can drive the eccentric cam to rotate, thereby realizing the reciprocating motion of the connecting rod away from the eccentric wheel end, thereby driving the cutter to extend into the straw film and retreat to avoid the second reel.

[0058] In addition, the tube cutting assembly in this embodiment may also include a cross guide rail, through which the movement of the cutting blade is guided to improve the movement accuracy of the blade, so that the blade can cut the straw at the same height and angle, thereby improving the cutting accuracy.

[0059] In this embodiment, if Figure 1 As shown, a guide block 240 may be further provided on the outer side of the second reel tube, and the guide block 240 is in an arc shape close to the second reel tube 230 side and is concentric with the second reel tube, and a stepping channel that can completely accommodate the straw is formed between the inner side of the second reel tube and the arc groove, and the guide block extends from the top of the outer side of the second reel tube along the rotation direction of the second reel tube to one side of the bottom of the second reel tube.

[0060] The guide block 240 is used to limit the position of the straw belt so that the straw is always contained in the arc groove of the second reel, so that the straw moves with the second reel without being separated until the straw moves to the bottom of the second reel.

[0061] Embodiment 2:

[0062] In order to realize the automatic discharge of the straw, this embodiment is optimized based on embodiment 1, such as Figure 3 , 4 As shown, different from Example 1, the tube cutting device in this embodiment also includes a tube feeding and conveying assembly 300, which can drive a single straw to move. The single straw is formed by cutting the straw strip by the tube cutting assembly. The tube feeding and conveying assembly 300 is arranged as a whole below the second tube winding tube. The tube feeding and conveying assembly 300 includes a straw mold conveyor 310. The surface of the conveying part of the straw mold conveyor 310 is provided with an arc groove that can partially accommodate the straw. The arc groove on the straw mold conveyor 310 and the arc groove on the second tube winding tube can form a hole that can completely accommodate the straw.

[0063] The straw driven to the bottom by the second tube reel enters the arc groove on the straw mold conveyor under its own gravity to convey away the single straw rolled out by the second tube reel, thereby realizing automatic discharge of the straws.

[0064] In this embodiment, the second power device can be selected as a servo motor, which is connected to the second tube reel and the straw mold conveyor through a cam divider, and the cam divider is connected to the above-mentioned cam through a support leg commutator. The second power device drives 12 cam dividers to rotate, when the input shaft end of the cam divider rotates one circle, the driven shaft end connected to the right-angle commutator rotates one circle synchronously, and the driven shaft end 2 connected to the second tube reel and the straw mold conveyor rotates 18°, and only within 90° of one circle of the input shaft, the driven shaft end 2 connected to the second tube reel and the straw mold conveyor will rotate 18°. When the input shaft rotates the remaining 270°, the driven shaft end connected to the second tube reel and the straw mold conveyor does not rotate. The straw mold conveyor can be connected to the second tube reel through a pulley transmission mechanism, thereby realizing the simultaneous driving of the second tube reel and the straw mold conveyor to step and feed the tube, and the driven shaft end connected to the right-angle commutator rotates, and the rotational power is transmitted to the eccentric cam through the right-angle commutator. The eccentric cam drives the connecting rod to swing, and then drives the second tube reel to cut the straw film and retreat to avoid it.

[0065] In one tube cutting linkage action, the cutter rotates 270° under the power of the cam divider to reach into and cut the straw film, retracts to allow the second tube roll to rotate one grid, and the second tube roll rotates one grid within a certain 90° rotation stroke after the cutter retracts, sending out a straw with the film cut off and sending in the next straw that needs to be cut.

[0066] like Figure 5 As shown, in this embodiment, the above-mentioned straw delivery assembly 300 may further include a guide slide 320, which extends from above the straw mold conveyor along its conveying direction to below the straw mold conveyor.

[0067] By arranging the guide slide, the end of the guide slide is arranged at a preset position below the straw mold conveyor, thereby guiding the straw to fall from the preset position below the straw conveyor.

[0068] Embodiment 3:

[0069] Since the high-speed tube cutting device in Example 2 cannot realize directional delivery of the straws, and the delivery method in the prior art is mostly a single-cut and single-release mode, that is, one straw is cut and delivered, which is inefficient.

[0070] Therefore, in order to solve the above technical problems, this embodiment proposes improvements based on embodiment 2, such as Figure 6 As shown, the pipe cutting device in this embodiment further includes an opening and closing component 500, which is connected to one end of the guide slideway arranged below the straw mold conveyor. The opening and closing component 500 is provided with two groups, and the two groups of the opening and closing components are symmetrically installed on opposite sides of the straw mold conveyor. The opening and closing component 500 can expose the straw to discharge the straw. The opening and closing component includes:

[0071] A fifth power device 510, which is installed on one side of the straw mold conveyor. The fifth power device 510 can be a cylinder; and

[0072] The baffle plate 320 is driven by the fifth power device 510 to move linearly in a direction horizontally perpendicular to the straw mold conveyor, and one side of the baffle plate 320 is connected to one end of the guide slideway arranged below the straw mold conveyor.

[0073] In addition, if Figure 5 , 7 As shown in FIG. 8 , the high-speed tube cutting device in this embodiment further includes a pick-up and placement mechanism 420, which is disposed as a whole below the above-mentioned opening and closing assembly. The suction structure moves close to the conveying surface of the straw mold to suck the straws moved to the position of the opening and closing assembly. The conveying surface of the straw mold to which the pick-up and placement mechanism moves close is equipped with an opening and closing assembly, such as Fig. 9As shown, the pick-and-place mechanism 420 includes:

[0074] A fourth power device 424, wherein the fourth power device 424 may be a servo motor; and

[0075] The negative pressure block 421 is driven to rotate eccentrically by the fourth power device 424. The negative pressure blocks are arranged in an array, and the negative pressure blocks in the array are equidistantly arranged along the conveying direction of the straw mold conveyor.

[0076] In this embodiment, the above-mentioned pick-and-place mechanism further includes:

[0077] A third power device 422, which may be a servo motor; and

[0078] The equal-distance variable module 423 is connected to the third power device, and the negative pressure block 421 is connected to the equal-distance variable module.

[0079] The straw driven to the bottom by the second tube reel enters the arc groove on the straw mold conveyor under its own gravity to convey the single straw rolled out by the second tube reel. The straw mold conveyor moves the straw to the bottom along the guide slide and is sent between the baffle and the straw mold conveyor. When the number of straws between the baffle and the straw mold conveyor reaches a preset number, the fourth power device drives the negative pressure block to swing to a horizontal state close to the straw. After it is in place, the opening and closing cylinder drives the baffle to move outward to release the straw. The negative pressure block sucks the straw, and the fourth power device drives the negative pressure block to swing downward at a small angle. The third power device provides power for the variable distance module to increase the spacing of the negative pressure blocks, and the negative pressure straw closes to release the straw.

[0080] like Fig. 9As shown, the second power device 422 in this embodiment is fixedly installed on one side of the equal-distance variable module 423. The equal-distance variable module is a device in the prior art that can realize the equal-distance linear movement of parts to make the parts equidistantly pulled apart or equidistantly brought together. There is a variable-distance shaft in the equal-distance variable module, which is connected to the second power device. The above-mentioned negative pressure block is connected to the variable-distance shaft. Through the rotation of the variable-distance shaft, the equal-distance pulling apart and bringing together of multiple negative pressure blocks can be achieved. A guiding mechanism can also be set between the negative pressure block and the equal-distance variable module to guide the movement of the negative pressure block. In addition, the equal-distance variable module in this embodiment is integrally It is eccentrically connected to the output shaft of the third power device, and the equal-distance module is driven to swing by the third power device. When the cut film straws need to be taken, the equal-distance module first shrinks the spacing by equal-distance, and then the equal-distance module is swung to a horizontal state close to the straws. After it is in place, the opening and closing cylinder opens to release the straws, and the negative pressure block on the equal-distance module sucks the straws. The equal-distance module swings downward at a small angle and the variable distance module opens the spacing by equal-distance. The negative pressure straw closes to release the straws, and the straws fall into the subsequent mechanism through the slide 410. In this embodiment, the picking and placing mechanism, the slide and the opening and closing components cooperate with each other to form a straw discharge mechanism 400.

[0081] The straws with cut film are transported backward through the straw mold to the lower end to the opening and closing component. The tube cutting component and the straw mold conveyor continuously cut 6 straws and send them to the opening and closing component. The opening and closing cylinder opens the baffle to allow the suction cup on the variable distance module to suck away 6 straws at a time. After closing, the straws can be transported into place and wait for the next material removal by the variable distance module.

[0082] This embodiment can cut out a plurality of straws continuously and then put them in one batch, which greatly reduces the size and cost of the equipment and improves the production capacity of the equipment.

[0083] In order to realize the automatic feeding of the straw belt, Figure 5 As shown, the pipe cutting device in this embodiment may also include a pipe delivery assembly 100, and the pipe delivery assembly 100 can drive the straw belt to be delivered into the pipe cutting device, such as Figure 7 , 9 As shown, the delivery pipe assembly includes:

[0087] The pipe delivery slide 111 allows the straw belt to move along its extension direction. One end of the pipe delivery slide is in an arc shape concentric with the second pipe reel 230. A pipe delivery channel that can fully accommodate the straw is formed between the arc-shaped end of the pipe delivery slide and the arc groove on the second pipe reel. The arc-shaped end of the pipe delivery slide extends from an upper part of one side of the second pipe reel along the rotation direction of the second pipe reel to the top of the second pipe reel.

[0088] Furthermore, the pipe delivery assembly further comprises a straw buffer bin 130, which is disposed below the first pipe reel, and a detection sensor is disposed on one side of the straw buffer bin to detect the straw material level in the straw buffer bin.
