[0008] Furthermore, the sealing knife assembly includes at least two heat sealing knives and one cooling sealing knife arranged sequentially along the rotation direction of the second turntable.

[0009] Furthermore, protective boxes are provided above both the heat sealing knife and the cooling sealing knife.

[0010] Furthermore, the first turntable includes a first turntable body and a first placement rack; The first plate is rotatably connected to the frame, and a plurality of the first placement racks are evenly fixed to the first plate at circumferential intervals along the first plate. The first placement rack extends radially outward along the first disc body, and a first limiting block is fixed on the side of the first placement rack away from the first disc body. The first limiting block is detachably connected to the first placement rack. The first limiting block has a first placement groove that extends through its upper and lower surfaces, and the first placement groove also extends through the side surface of the first limiting block away from the first disc body; the inner wall of the first placement groove and its upper surface together define the first placement position.

[0011] Furthermore, the straw feeding assembly includes a straw storage bin, a material sorting vibratory plate, a material guiding mechanism, and a straw feeding mechanism arranged sequentially along the straw conveying direction; The straw storage bin is mounted on the frame, and a pipe outlet is provided on its upper surface. The pipe outlet defines the inlet end of the straw feeding assembly. The bottom of the straw storage bin is provided with a pipe outlet, which is connected to the inlet of the material feeding vibrating plate. The outlet of the material feeding vibrating plate is connected to the inlet of the feeding mechanism through a downwardly inclined material guiding mechanism. The material handling vibratory feeder is used to organize the suction tubes and transport them to the material guiding mechanism. The material guiding mechanism is used to transport the suction tubes one by one to the tube feeding mechanism. The tube feeding mechanism is used to push the suction tubes one by one to the first placement position located at the tube feeding station.

[0012] Furthermore, the material guiding mechanism includes a fixing frame and a limiting plate; The fixing frame is fixed to the upper surface of the frame and is located between the material feeding vibratory plate and the upper tube mechanism; A pair of limiting plates are arranged parallel to each other at intervals and are detachably connected to the fixing frame; the two ends of the limiting plates are respectively aligned with the outlet of the material feeding vibratory plate and the inlet of the upper tube mechanism; The gap between the pair of limiting plates defines a guide groove, the width of which is adapted to the outer diameter of the suction tube.

The machine sequentially performs straw placement, soft bag placement, and transitional placement at one of the first placement positions, inserts a soft bag into the straw, and pushes the straw and soft bag together to one of the second placement positions on the second turntable. The straw and soft bag at the second placement position follow the movement of the second turntable, and the sealing knife assembly seals the soft bag and straw before moving to the second placement position. The material is pushed out of the frame by the second pushing mechanism at the material station, thereby achieving soft bag sealing. Compared with sealing machines arranged in an assembly line, the soft bag sealing machine uses a first turntable to load the tube and bag, and then uses a second turntable to seal and push out the bag, optimizing the spatial arrangement of each mechanism and reducing the footprint of the soft bag sealing machine.

[0018] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0019] like Figure 1 As shown, a soft bag sealing machine 100 according to an embodiment of the present invention includes a frame 1, a straw feeding assembly 2, a bag placement mechanism 3, a first pushing mechanism 4, a sealing knife assembly 5, a second pushing mechanism 6, a first turntable 7, and a second turntable 8. The first turntable 7 and the second turntable 8 are rotatably spaced apart on the upper surface of the frame 1 along the first direction X; the first turntable 7 and the second turntable 8 each have a plurality of first placement positions and second placement positions spaced apart along their own circumference. The first turntable 7 has a tube feeding station 101 on one side in the second direction Y. The discharge end of the straw feeding assembly 2 is located at the feeding station. The straw feeding assembly 2 is used to transport the straw to the first placement position located at the tube feeding station 101. The first turntable 7 has a bag placement station 102 on the side away from the second turntable 8. The bag placement mechanism 3 is located at the bag placement station 102 and is used to put the soft bag into the straw located at the first placement position of the bag placement station 102. The bag placement mechanism 3 and the feeding end of the straw feeding assembly 2 are arranged adjacent to each other in the second direction Y. A transition station 103 is provided between the first turntable 7 and the second turntable 8. The first pushing mechanism 4 is located at the transition station 103 and is used to push the material located at the first placement position of the transition station 103 to the second placement position. The outer side of the second turntable 8 is provided with a pushing station 104. The transition station 103, the sealing knife assembly 5 and the pushing station 104 are arranged in sequence along the rotation direction of the second turntable 8. The sealing knife assembly 5 is used to seal the soft bag and the straw. The second pushing mechanism 6 is provided at the pushing station 104 and is used to push the material located at the second placement position of the pushing station 104 out of the frame 1. Among them, the first direction X and the second direction Y are perpendicular to each other on the horizontal plane.

[0020] Based on the above technical solution, the straw is placed at the first placement position, the soft bag is inserted into the straw, and the straw and soft bag are pushed together to one of the second placement positions of the second turntable 8 through the straw placement station 101, the bag placement station 102, and the transition station 103. The straw and soft bag in the second placement position follow the movement of the second turntable 8 and are sealed by the sealing knife assembly. Then they move to the pushing station 104 and are pushed out of the frame 1 by the second pushing mechanism 6, thereby sealing the soft bag. Compared with the sealing machine equipment arranged in an assembly line, the soft bag sealing machine realizes the straw and bag feeding through the first turntable 7 and the sealing and pushing through the second turntable 8, which optimizes the spatial arrangement of each mechanism and reduces the footprint of the soft bag sealing machine 100. Moreover, the bag placement mechanism 3 and the feeding end of the straw feeding assembly 2 are adjacent in the second direction Y, so that the workers can stand in one position to complete the feeding of straw and soft bag at the same time, which greatly reduces the labor cost.

[0021] Furthermore, such as Figure 1 and Figure 2 As shown, the soft bag sealing machine 100 also includes a preheating sealing knife mechanism 9; The straw feeding assembly 2, bag placement station 102, preheating sealing mechanism 9, and transition station 103 are sequentially arranged on the outside of the first turntable 7 along the rotation direction of the first turntable; the preheating sealing mechanism 9 is used to heat seal the soft bag and the straw.

[0022] It is understood that the preheating sealing mechanism 9 can perform a heat seal on the soft bag and straw before they are conveyed to the second turntable 8, thereby achieving pre-sealing and positioning of the soft bag and straw to avoid inaccurate sealing position caused by relative displacement of the soft bag and straw during the conveying process.

[0023] Furthermore, such as Figure 1 and Figure 2 As shown, the sealing knife assembly 5 includes at least two heat sealing knives 51 and one cooling sealing knife 52 arranged sequentially along the rotation direction of the second turntable.

[0024] Understandably, in order to improve the reliability of the straw and soft bag sealing and to prevent the sealed soft bag from deforming due to lack of cooling during the push-out or subsequent conveying process, a sealing process of multiple heat sealing and cooling is formed by at least two heat sealing knives and one cooling sealing knife arranged in sequence. At least two heat sealing knives 51 and one cooling sealing knife 52 are arranged in sequence along the rotation direction of the second turntable so that heat sealing and cooling are performed sequentially by the rotation of the second turntable 8.

[0025] Preferably, such as Figure 1 and Figure 2 As shown, in this embodiment, four heat-sealing blades 51 are provided to form a sealing process of four heat sealing and one cooling.

[0026] Furthermore, such as Figure 1 and Figure 2 As shown, in order to reduce temperature changes during heat sealing and cooling to ensure the reliability of heat sealing and cooling, a protective box 50 is provided above both the heat sealing knife 51 and the cooling sealing knife 52.

[0027] Furthermore, such as Figures 1-3 As shown, the first turntable 7 includes a first disc body 71 and a first placement rack 72; The first disc body 71 is rotatably connected to the frame 1, and a plurality of first placement racks 72 are evenly fixed to the first disc body 71 at circumferential intervals. The first placement rack 72 extends outward along the radial direction of the first disc body 71. A first limiting block 73 is fixed on the side of the first placement rack 72 away from the first disc body 71. The first limiting block 73 is detachably connected to the first placement rack 72. The first limiting block 73 has a first placement groove 730 that extends through its upper and lower surfaces. The first placement groove 730 also extends through the side surface of the first limiting block 73 away from the first disc body 71. The inner wall of the first placement groove 730 and its upper surface together define the first placement position.

[0028] It is understandable that, since the first placement groove 730 penetrates the upper and lower surfaces of the first limiting block 73 and the side surface of the first limiting block 73 away from the first disc 71, the straw can be pushed in and placed through the first placement groove 730; in order to improve the applicability of the soft bag sealing machine 100 and make it applicable to sealing straws of different specifications, the first limiting block 73 is detachably connected to the first placement frame 72, so that the first limiting block 73 of different specifications can be replaced according to the straws of different specifications.

[0029] Similarly, such as Figure 1 , Figure 2 and Figure 4 As shown, to match the first limiting block 73; the second turntable 8 includes a second disc body 81 and a second placement rack 82; The second disk body 81 is rotatably connected to the frame 1, and a plurality of second placement racks 82 are evenly fixed to the second disk body 81 at circumferential intervals. The second placement rack 82 extends outward along the radial direction of the second disc body 81. A second limiting block 83 is fixed on the side of the second placement rack 82 away from the second disc body 81. The second limiting block 83 is detachably connected to the second placement rack 82. The second limiting block 83 has a second placement groove 830 that extends through its upper and lower surfaces. The second placement groove 830 also extends through the side surface of the second limiting block 83 away from the second disc body 81. The inner wall of the second placement groove 830 and its upper surface together define the second placement position.

[0030] Preferably, such as Figures 1-3 As shown, in order to improve the sealing efficiency of the soft bag sealing machine 100, two first limiting blocks 73 are provided at intervals on each of the first placement racks 72, so that each first placement rack 72 has two first placement positions.

[0031] Accordingly, such as Figure 1 , Figure 2 and Figure 4 As shown, each of the second placement racks 82 is provided with two second limiting blocks 83 at intervals, so that each second placement rack 82 has two second placement positions.

[0032] Furthermore, the straw feeding assembly 2 includes a straw storage bin 21, a material sorting vibrating plate 22, a material guiding mechanism 23, and a straw feeding mechanism 24 arranged sequentially along the straw conveying direction; The straw storage bin 21 is mounted on the frame 1, and its upper surface has a pipe outlet. The pipe outlet defines the inlet end of the straw feeding assembly. The bottom of the straw storage bin 21 has a pipe outlet, which is connected to the inlet of the material feeding vibrating plate 22. The outlet of the material feeding vibrating plate 22 is connected to the inlet of the pipe feeding mechanism 24 through a downwardly inclined material guiding mechanism 23. The material handling vibratory plate 22 is used to organize the suction tubes and transport them to the material guiding mechanism 23. The material guiding mechanism 23 is used to transport the suction tubes one by one to the tube feeding mechanism 24. The tube feeding mechanism 24 is used to push the suction tubes one by one to the first placement position located at the tube feeding station.

[0033] It is understood that the straws are fed through the straw storage bin 21, and the straws are sorted by the material handling vibrating plate 22 and transported to the material guiding mechanism 23. The inclined material guiding mechanism transports the straws to the upper tube mechanism by their own weight, and finally the upper tube mechanism 24 pushes out the straws one by one.

[0034] Furthermore, such as Figure 5 As shown, the material guiding mechanism 23 delivers the straws one by one; the material guiding mechanism 23 includes a fixed frame 231 and a limiting plate 232. The fixed frame 231 is fixed to the upper surface of the frame 1 and is located between the material feeding vibratory plate 22 and the upper tube mechanism 24; A pair of limiting plates 232 are arranged parallel to each other and detachably connected to the fixing frame 231; the two ends of the limiting plates 232 are respectively aligned with the outlet of the material feeding vibratory plate 22 and the inlet of the upper tube mechanism 24. The gap between the pair of limiting plates 232 defines a guide groove 230, the width of which is adapted to the outer diameter of the straw. Therefore, the guide groove 230, whose width is adapted to the outer diameter of the straw, limits the straws to be arranged one by one in the guide groove, thereby realizing the one-to-one delivery of the straws by the guiding mechanism 23. In addition, similar to the setting of the first limiting block 73, in order to make the width of the guide groove 230 change to suit straws of different specifications, the limiting plate 232 is detachably connected to the fixing frame 231 so as to adjust the installation position of the limiting plate 232 according to straws with different outer diameters to change the width of the guide groove 230.

[0035] Furthermore, such as Figure 1 and Figure 2As shown, in order to remove defective products, the soft bag sealing machine 100 also includes a third pushing mechanism 20; The frame is also provided with a waste removal station 105. The transition station 103, the sealing knife assembly 5, the material pushing station 104 and the waste removal station 105 are arranged in sequence along the rotation direction of the second turntable 8. The frame 1 is provided with a material discharge port 10. The material discharge port 10 and the third pushing mechanism 20 are arranged on both sides of the waste rejection station 105 along the radial direction of the second turntable 8. The third pushing mechanism 20 is used to push the material located at the second placement position of the waste rejection station 105 into the material discharge port 10.

[0036] It should be noted that the material testing is carried out by testing instruments or testing mechanisms, which are all mature existing technologies and will not be elaborated here. The testing instrument is electrically connected to the power source that controls the rotation of the second turntable 8. When the test result is a defective product, the corresponding second placement position is directly moved to the rejection station 105, and the defective product is pushed into the discharge port 10 by the third pushing mechanism 20, so as to realize the automatic rejection of defective products from the production line.

[0037] Furthermore, such as Figure 1 and Figure 2 As shown, the soft bag sealing machine 100 also includes a receiving mechanism 30; The receiving mechanism 30 is located on the side of the pushing station 104 away from the second turntable 8. The top of the receiving mechanism 30 has a receiving station 301 for temporarily storing materials or for facilitating the sorting and picking of materials by staff.

[0038] Preferably, in this embodiment, the first pushing mechanism 4, the second pushing mechanism 6, the third pushing mechanism 20 and the upper tube mechanism 24 are all reciprocating motion mechanisms. Such mechanisms are common drive mechanisms and are mature existing technologies, and will not be described in detail here. They can be selected according to actual needs.

[0039] Preferably, such as Figures 1-3 As shown, in this embodiment, since the outer side of the first turntable 7 is sequentially provided with a tube placement station 101, a bag placement station 102, a preheating sealing mechanism 9, and a transition station 103, to match this arrangement, four first placement racks 72 are evenly fixed to the first disc body 71 at circumferential intervals, that is, adjacent two first placement racks 72 are spaced 90° apart, so that the first disc body 71 can be rotated at 90° by a stepper motor or other means, so that each first placement position can correspond to the tube placement station 101, the bag placement station 102, the preheating sealing mechanism 9, or the transition station 103 respectively, so as to ensure the working efficiency of the first turntable 7.

[0040] Similarly, such as Figure 1 , Figure 2 and Figure 4 As shown, to ensure that each of the second placement positions on the second turntable 8 corresponds to the transition station, the four heat-sealing knives, the cooling sealing knives, the material pushing station 104, or the waste removal station 105, the diameter of the second turntable 8 is larger than the diameter of the first turntable 7, and the eight second placement frames 82 are evenly fixed to the second disc body 81 along the circumference of the second disc body 81, that is, the adjacent two second placement frames 82 are set at a 45° interval. The working process of this invention is as follows: The staff member stands on the side of the frame 1 closest to the first turntable 7 in the first direction and puts soft bags and straws into the bag feeding mechanism 3 and the straw storage bin 21 respectively.

[0041] The first turntable 7 rotates, driving one of the first placement positions to the tube placement station 101. The straws in the straw storage bin 21 enter the material handling vibrating plate 22 and are conveyed one by one to the tube uppering mechanism 24 through the material guiding mechanism 23. The tube uppering mechanism 24 pushes the straws one by one into the first placement groove 730 of the first limiting block 73. The first turntable 7 rotates again and rotates to the bag placement station 102. The bag placement mechanism 3 puts the soft bag into the straw. The first turntable 7 rotates again and aligns with the preheating sealing knife mechanism 9. The preheating sealing knife mechanism 9 heat seals the straw and the soft bag.

[0042] The first turntable 7 rotates again and moves to the transition station 103. The first pushing mechanism 4 pushes the straw and soft bag in the first placement slot 730 to the second placement slot 830 in the second turntable 8 located in the transition station 103.

[0043] The second turntable 8 rotates and passes through and stops at four of the heat-sealing blades 51 and one of the cooling blades in sequence to complete the sealing process of four heat-sealing and one cooling.

[0044] The second turntable 8 continues to rotate according to the test results. If the product is qualified, the second turntable 8 rotates to the pushing station 104, and the second pushing mechanism 6 pushes the qualified finished product to the receiving station 301 of the receiving mechanism 30. If the product is unqualified, the second turntable 8 rotates to the scrap rejection station 105, and the third pushing mechanism 20 pushes the unqualified finished product into the discharge port 10 for scrapping.

[0045] In summary, this invention provides a soft bag sealing machine 100, which includes a frame 1, a straw feeding assembly 2, a bag placement mechanism 3, a first pushing mechanism 4, a sealing knife assembly 5, a second pushing mechanism 6, a first turntable 7, and a second turntable 8. Through the straw placement station 101, the bag placement station 102, and the transition station 103, straws are placed at one of the first placement positions in sequence; a soft bag is inserted into the straw; and the straw and soft bag are pushed together to one of the second placement positions on the second turntable 8. The straw and soft bag located at the second placement position follow the movement of the second turntable 8, and the sealing knife assembly seals the soft bag and straw. The bag is then moved to the pushing station 104 and pushed out of the frame 1 by the second pushing mechanism 6, thereby achieving soft bag sealing. Compared with sealing machines arranged in an assembly line, the soft bag sealing machine uses the first turntable 7 to load the tube and bag, and then uses the second turntable 8 to seal and push out the bag, optimizing the spatial arrangement of each mechanism and reducing the floor space of the soft bag sealing machine 100. In addition, the bag feeding mechanism 3 and the feeding end of the straw feeding component 2 are adjacent to each other in the second direction Y, so that the staff can stand in one position to complete the feeding of straws and soft bags at the same time, which greatly reduces labor costs.

[0046] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
