[0053] Unless specifically stated or defined otherwise, the term "and / or" used in the present invention includes any and all combinations of one or more of the associated listed items.

[0054] For the convenience of description, unless otherwise specified, the up and down directions mentioned below are the same as Figure 1 The up and down directions are consistent with the left and right directions mentioned below. Figure 1 The left and right directions are consistent with the Figure 1 The projection direction itself is consistent.

[0055] like Figures 1 to 12 As shown, the present embodiment provides a tube insertion device, which can push the straw 6 onto the product. The straw 6 of the present application is provided with a packaging film or packaging paper after production, and adjacent straws 6 are sequentially connected by materials such as a film 8 or paper. Therefore, the present application can cut the film 8 as required so that at least one straw 6 falls off and is separated and then pushed onto the product. The number of pushed straws 6 is set according to the number of products, for example, the number of products is the same as the number of straws 6.

[0056] The tube insertion device includes a product conveying mechanism 4, a reciprocating mechanism 3, a tube feeding and cutting mechanism 1, and a tube insertion mechanism 2. The product conveying mechanism 4 includes a product conveying channel 403. The product conveying channel 403 of the product conveying mechanism 4 can realize the conveyance of the product. In this embodiment, the product is a cup-type beverage 5, which is uniformly described as a cup body below. At least one cup body is a group, and each group of cup bodies is placed on the same cup holder 7. Then, the product conveying mechanism 4 is used to convey each group of cup bodies and cup holders 7. The tube insertion mechanism 2 can push the corresponding number of straws 6 into the gap between each group of adjacent cup bodies to complete the assembly.

[0057] The reciprocating mechanism 3 includes a slide 301 that slides back and forth along the extension path of the product conveying channel 403. The slide 301 is slidably disposed on one side of the product conveying channel 403, and the slide 301 can move synchronously with the product.

[0058] The tube feeding and cutting mechanism 1 comprises a tube feeding channel 101 and a movably mounted cutter 102. The tube feeding channel 101 is located on the moving path of the cutter 102, and has a tube inlet 122 and a tube outlet 123. The tube feeding channel 101 is used to convey a plurality of straws 6 with packaging film and connected in sequence through the film 8. The plurality of straws 6 move along the tube feeding channel 101 to achieve conveyance, and then the cutter 102 cuts the film 8 according to the number of straws 6 required for each group of products.

[0059] The tube insertion mechanism 2 is installed on the slide 301. The tube insertion mechanism 2 includes a material receiving trough 201 located below the tube outlet 123 and a movably installed tube pushing seat 202. The material receiving trough 201 and the product conveying channel 403 are arranged in sequence along the moving path of the tube pushing seat 202. After the cutter 102 separates the straw 6, the straw 6 falls into the material receiving trough 201, and then the tube pushing seat 202 pushes the straw 6 in the material receiving trough 201 onto the product on the product conveying channel 403, completing the assembly of the product and the straw 6. The slide 301 is used to drive the straw 6 in the material receiving trough 201 that needs to be pushed onto the cup body to move synchronously with each group of products. Each group of products does not need to stop conveying until the straw 6 is pushed and then conveyed, so the assembly of the straw 6 and the product can be completed without affecting the product conveying.

[0060] When the tube insertion device is working, the product conveying mechanism 4 conveys the cup holder 7 and the cup body on the cup holder 7, the tube conveying and cutting mechanism 1 conveys the straw 6 and cuts a corresponding number of straws 6 according to product requirements, and the cut and separated straws 6 fall into the material receiving trough 201, and the reciprocating mechanism 3 drives the straw 6 in the material receiving trough 201 to move synchronously with the cup holder 7, and the straw 6 moves to the cup holder 7 under the push of the tube pushing seat 202, and finally the cup holder 7 and the cup body and straw 6 on the cup holder 7 are sent to the next packaging process together.

[0061] Key References Figures 3 to 7In one embodiment, the pipe feeding and cutting mechanism 1 further includes a mounting plate 103, a guide seat 104, a pipe feeding wheel 105, a first cylinder 106, and a first motor 107. The mounting plate 103 is vertically arranged, the guide seat 104, the first cylinder 106, and the first motor 107 are all mounted on the front end surface of the mounting plate 103, the pipe feeding wheel 105 is rotatably mounted on the mounting plate 103, and the first motor 107 is transmission-connected to the pipe feeding wheel 105. Specifically, the pipe feeding and cutting mechanism 1 further includes a reducer 319, a first driving pulley 118, a first driven pulley 119, a first synchronous belt 120, and a tensioning pulley 121. The first driving pulley 118, the first driven pulley 119, and the tensioning pulley 121 are all rotatably mounted on the mounting plate 103, and the first synchronous belt 120 is sleeved on the first driving pulley 118 and the first driven pulley 119. The output end of the first motor 107 is connected to the reducer 319, which is connected to the first driving pulley 118. The first driving pulley 118 is connected to the first driven pulley 119 through the first synchronous belt 120. The first driven pulley 119 is connected to the tube delivery wheel 105 through the transmission connection hole. The tensioning wheel 121 realizes the tensioning of the first synchronous belt 120, thereby driving the tube delivery wheel 105 to rotate through the first motor 107, and the rotation of the tube delivery wheel 105 drives the straw 6 to move. The pipe delivery wheel 105 drives the straw 6 to move by friction between the outer circumferential side of the pipe delivery wheel 105 and the straw 6, or by providing a pipe groove 110 on the outer circumferential side of the pipe delivery wheel 105 to push the straw 6 to move. In this embodiment, the pipe groove 110 is provided on the outer circumferential side of the pipe delivery wheel 105. Compared with the method of pushing the straw 6 to move by friction between the outer circumferential side of the pipe delivery wheel 105 and the straw 6, the pipe groove 110 is provided to push the straw 6 to move, which can prevent the straw 6 from being crushed.

[0062] The guide seat 104 has an arc guide surface 108, the center of which is located on the rotation axis of the pipe delivery wheel 105, and the arc guide surface 108 is spaced apart from the outer circumferential side surface of the pipe delivery wheel 105. The arc guide surface 108 and at least part of the outer circumferential surface of the pipe delivery wheel 105 together enclose a pipe delivery channel 101, and at least part of the pipe delivery channel 101 extends along an arc trajectory. The pipe inlet 122 is located at the upper end of the pipe delivery channel 101, and the pipe outlet 123 is located at the lower end of the pipe delivery channel 101. The suction pipe 6 is separated from the pipe outlet 123 from the pipe delivery channel 101 in sequence from top to bottom. The output end of the first cylinder 106 is transmission-connected to the cutter 102 to drive the cutter 102 to approach or move away from the pipe delivery channel 101. When the straw 6 passes through the pipe delivery channel 101, the cutter 102 approaches the pipe delivery channel 101 and cuts the film 8 between the straws 6. The straw 6 near the pipe outlet 123 falls from top to bottom into the receiving trough 201. The cutter 102 separates the straw 6 and moves away from the pipe delivery channel 101.

[0063] Optionally, there are multiple guide seats 104, tube delivery wheels 105, first cylinders 106, and first motors 107, and they correspond one to one, so that multiple tube delivery channels 101 can be used for tube delivery and tube cutting. The tube insertion mechanism 2 has multiple material receiving grooves 201 and multiple tube pushing seats 202, and each material receiving groove 201 corresponds to a tube delivery channel 101, thereby improving production efficiency.

[0064] In one embodiment, a cutting channel 109 connected to the tube delivery channel 101 is provided on the guide seat 104, and the cutting channel 109 and the tube delivery channel 101 are arranged in sequence along the moving path of the cutter 102. The cutter 102 enters the tube delivery channel 101 from the cutting channel 109 and squeezes the film 8 between the straws 6 close to the outer circumferential side of the tube delivery wheel 105, which is conducive to the cutting of the film 8 by clamping the cutter 102 and the outer circumferential side of the tube delivery wheel 105.

[0065] Furthermore, the pipe delivery channel 101 includes an arc segment and a straight segment connected in sequence from top to bottom, and the straight segment extends vertically. The first cylinder 106 is tilted, and the cutter 102 approaches the straight segment of the pipe delivery channel 101 along a straight track tilted from top to bottom, so that the cutter 102 forms a certain angle with the film 8 when cutting the film 8, which can greatly increase the cutting speed, make the film 8 easier to cut, reduce the cutting time, improve the production efficiency, and extend the life of the cutter 102.

[0066] Optionally, the blade of the cutter 102 has triangular shaped serrations. During the current production of straws 6 , in order to facilitate consumers to privately open the film 8 to separate two adjacent straws 6 , a serrated gap is provided on the film 8 . The blade of the present application has triangular shaped serrations, and the serrations cut the connection points between the gaps, which can not only further improve the cutting efficiency, but also reduce the contact area between the blade and the tube delivery wheel 105 , thereby reducing the wear of the tube delivery wheel 105 .

[0067] In other embodiments, the cutter 102 has a heating function, and the film 8 is cut by heat melting. The cutter 102 can also be replaced by ultrasonic cutting or other methods.

[0068] Furthermore, the guide seat 104 is slidably disposed on the mounting plate 103 , and the guide seat 104 can slide left and right, thereby adjusting the width of the pipe delivery channel 101 according to the type and diameter of the straw 6 .

[0069] In one embodiment, a plurality of tube grooves 110 are provided on the outer circumferential side of the tube delivery wheel 105, and each tube groove 110 extends along the rotation axis direction of the tube delivery wheel 105. The plurality of tube grooves 110 are arranged at intervals along the circumferential direction of the rotation axis of the tube delivery wheel 105. The width of the tube delivery channel 101 is smaller than the diameter of the straw 6, so that when the straw 6 is delivered, each straw 6 corresponds to a tube groove 110 and is inserted into the tube groove 110. The film 8 between adjacent straws 6 passes through the tube delivery channel 101 and abuts against the outer circumferential side of the tube delivery wheel 105, and the tube grooves 110 are used to realize the positioning of the straw 6. When the tube delivery wheel 105 rotates, the inner wall of the tube groove 110 pushes the straw 6 to move to realize delivery.

[0070] Optionally, an escape groove 111 is further provided on the outer circumferential side of the tube delivery wheel 105, and an escape groove 111 is provided between any adjacent tube grooves 110, and each escape groove 111 extends along the rotation axis direction of the tube delivery wheel 105. When the straws 6 are delivered, the film 8 is stretched tight in the escape groove 111, so that when the cutter 102 cuts the film 8 between the straws 6, the cutter 102 is inserted into the escape groove 111 to cut the film 8, and the cutter 102 can complete the cutting without contacting the escape groove 111.

[0071] Furthermore, the pipe feeding and cutting mechanism 1 further comprises a pipe stopper 117 mounted on the mounting plate 103. The depth of the pipe groove 110 along the radial direction of the pipe feeding wheel 105 is slightly smaller than the diameter of the straw 6, and part of the outer circumferential side surface of the straw 6 protrudes outside the outer circumferential side surface of the pipe feeding wheel 105. The pipe stopper 117 is located at the pipe outlet 123 and on the moving path of the straw 6. The gap between the pipe stopper 117 and the outer circumferential side surface of the pipe feeding wheel 105 is very small. The pipe stopper 117 is used to block the part of the straw 6 protruding outside the outer circumferential side surface of the pipe feeding wheel 105, so as to prevent the cut and separated straw 6 from falling down from the pipe outlet 123 as the pipe feeding wheel 105 continues to rotate. At the same time, the avoidance groove 111 of the present application is located between any adjacent tube grooves 110. When the diameter of the straw 6 is larger than the width of the tube groove 110 along the circumferential direction of the tube feeding wheel 105, the tube feeding wheel 105 can produce a certain elastic deformation. The width of the avoidance groove 111 becomes smaller, so that the size of the tube groove 110 becomes larger. The tube groove 110 can adapt to and clamp straws 6 of different sizes. After the film 8 between the straws 6 is cut off, the straw 6 will not be stuck in the tube groove 110 and cannot fall off under the obstruction of the tube blocking seat 117.

[0072] Optionally, a separation groove 112 is further provided on the outer circumferential side of the tube delivery wheel 105, and there is at least one separation groove 112, and a plurality of separation grooves 112 are arranged at intervals along the rotation axis direction of the tube delivery wheel 105. Each separation groove 112 extends along the circumference of the tube delivery wheel 105, so that the tube groove 110 and the avoidance groove 111 of the tube delivery wheel 105 are divided into at least two ends by the separation groove 112, and the lengths of the tube groove 110 and the avoidance groove 111 of each section can be set to be different, which can not only adapt to straws 6 of different lengths, but also make the deformation of the tube delivery wheel 105 easier through the separation groove 112, and the straw 6 is not easy to get stuck in the tube groove 110.

[0073] In one embodiment, the pipe feeding and cutting mechanism 1 further includes a guide wheel 113 rotatably mounted on the mounting plate 103. The guide wheel 113 is located at the pipe inlet 122 of the pipe feeding channel 101. Limiting plates are provided at both ends of the axial direction of the guide wheel 113, and a limiting groove is formed between the two limiting plates, and the straw 6 passes through the limiting groove. Through the guidance of the pipe feeding wheel 105 and at least one guide wheel 113, the straw 6 enters the pipe feeding channel 101 along an arc or S-shaped trajectory, and multiple straws 6 form a pipe chain through the film 8, so as to achieve guidance and pre-tightening of the pipe chain during transportation.

[0074] Optionally, the tube feeding and cutting mechanism 1 further includes a first guide plate 114 and a second guide plate 115 arranged at intervals on the mounting plate 103. A guide channel 116 connected to the tube outlet 123 of the tube feeding channel 101 is formed between the first guide plate 114 and the second guide plate 115, and the guide channel 116 is located above the material receiving trough 201 and below the tube blocking seat 117. The width of the guide channel 116 gradually decreases from top to bottom, and the first guide plate 114 and the second guide plate 115 are used to make the straws 6 that need to be placed on the same cup holder 7 gather and fall into the material receiving trough 201.

[0075] Key References Figures 8 to 9 In one embodiment, the tube inserting mechanism 2 further includes a tube receiving seat 203 and a second cylinder 204 installed on the tube receiving seat 203. The material receiving trough 201 is provided on the tube receiving seat 203, and the output end of the second cylinder 204 is in transmission connection with the tube pushing seat 202. The tube pushing seat 202 can be driven by the second cylinder 204 to slide relative to the tube receiving seat 203, so that the tube pushing seat 202 can push the straw 6 in the material receiving trough 201 onto the cup holder 7.

[0076] Optionally, the cannulation mechanism 2 further includes a third cylinder 205, a gathering seat 207, a bottom plate 209, a connecting plate 210, and a piston seat 211. The connecting seat 203 and the third cylinder 205 are mounted on the bottom plate 209, and the second cylinder 204 is movably mounted on the connecting seat 203. Specifically, the second cylinder 204 is mounted on the connecting plate 210, and the output end of the third cylinder 205 is connected to the connecting plate 210. Under the drive of the third cylinder 205, the second cylinder 204 can slide relative to the connecting seat 203. One end of the piston seat 211 is mounted on the connecting plate 210, and the other end of the piston seat 211 is slidably arranged on the material receiving groove 201. The section of the piston seat 211 along the perpendicular sliding direction is the same as the section of the material receiving groove 201. The piston seat 211 is provided with a rod hole 212 extending along the sliding direction of the piston seat 211. The rod hole 212 is used for the output end of the second cylinder 204 and the push tube seat 202 to pass through. The gathering seat 207 is connected to the connecting pipe seat 203 and is arranged in the gathering channel 208 connected to the material receiving groove 201. The section of the gathering channel 208 is smaller than the section of the material receiving groove 201, and the section of the gathering channel 208 at one end connected to the material receiving groove 201 gradually decreases, and the section of the gathering channel 208 at one end away from the material receiving groove 201 remains unchanged. The section of the push tube seat 202 is the same as the part where the section of the gathering channel 208 remains unchanged. In this way, when the straw 6 falls into the material receiving groove 201 of the connecting pipe seat 203, the insertion mechanism 2 starts to work. When the tube insertion mechanism 2 is working, the third cylinder 205 drives the piston seat 211 to slide in the material receiving trough 201 and approach the gathering channel 208. After the piston seat 211 moves to the connection between the receiving seat 203 and the gathering seat 207, the straw 6 enters the gathering channel 208. Under the gathering effect of the gathering channel 208, multiple straws 6 are gathered. Finally, the second cylinder 204 drives the tube pushing seat 202 to extend into the gathering channel 208 to push the straw 6 onto the cup holder 7.

[0077] Furthermore, when the output end of the second cylinder 204 moves along the extension direction, the gathering seat 207 moves in the receiving trough 201 in the direction away from the gathering seat 207, and when the output end of the third cylinder 205 moves along the contraction direction, the tube pushing seat 202 moves in the direction close to the gathering seat 207. In this way, when pushing the tube, the output end of the second cylinder 204 and the output end of the third cylinder 205 move in opposite directions, that is, the extension direction of the output end of the second cylinder 204 and the extension direction of the output end of the third cylinder 205 are opposite, thereby reducing the length of the tube insertion mechanism 2 along the tube pushing direction and reducing the volume of the tube insertion mechanism 2.

[0078] Optionally, the tube insertion mechanism 2 further comprises a gathering pressing piece 206 rotatably mounted on the gathering seat 207. One end of the gathering pressing piece 206 is rotatably mounted above the gathering channel 208, and the other end of the gathering pressing piece 206 falls into the gathering channel 208 under the action of gravity. The gathering pressing piece 206 is an arc strip extending in a direction away from the tube pushing seat 202, and the outer arc surface of the gathering pressing piece 206 faces the bottom wall of the gathering channel 208. In this way, when the second cylinder 204 drives the tube pushing seat 202 to enter the gathering channel 208 to push the straw 6 onto the cup holder 7, under the action of gravity of the gathering pressing piece 206, the gathering pressing piece 206 presses the multiple straws 6 downward so that the multiple straws 6 are further gathered.

[0079] Furthermore, a limiting strip 213 is provided on the receiving seat 203 , and the limiting strip 213 prevents the piston seat 211 from being separated from the receiving groove 201 .
