Description

Technical Field

[0001] This invention relates to the field of pasteurized straw manufacturing technology, specifically to a straw conveying device and straw forming equipment. Background Technology

[0002] Pasteur pipettes, also known as Pasteur pipettes, are disposable pipettes, typically made of transparent polyethylene, a high-molecular-weight material that can be sterilized by gamma rays. They are ideal liquid carriers in cell experiments, clinical trials, and other experiments. Due to their polyethylene composition, they possess high permeability and flexibility, allowing them to be bent at any angle, making them widely applicable. They are primarily used for the aspiration, transfer, or transport of small amounts of liquid in cell experiments, clinical trials, and cloning experiments. The tube has a hollow sac for easy mixing of solvents, pharmaceuticals, and cells. The tube is translucent and bright white, with ideal liquid flow and high controllability; it can be used in liquid nitrogen environments. Its slender, flexible, and bendable body facilitates the insertion and removal of micro-volume or special containers; the small tip ensures repeatable drops; and the end can be heat-sealed for convenient liquid transport.

[0003] Currently, blow molding is commonly used in the industry to manufacture Pasteur straws. For example, the applicant's earlier patent application, publication number CN113478785A, discloses a multi-station straw blow molding equipment and straw manufacturing method. The blow molding equipment includes an extruder and a forming module. The forming module includes a blowing mechanism and a forming die. The forming die is used to hold the raw material extruded by the extruder and transports the raw material to the lower end of the blowing mechanism to complete the blow molding into a semi-finished straw. After blow molding, the forming die detaches from the semi-finished straw. The forming module also includes a shearing die for holding the semi-finished straw after detachment from the forming die and for cutting the semi-finished straw within the shearing die. This patent first blow molds a semi-finished straw in the forming module. The end of the semi-finished straw away from the capsule is a discarded end, which is subsequently cut off to obtain the finished straw. The cutting process is also completed within the mold cavity. However, some straws require an additional stretching process on the finished product to lengthen and thin the straw, followed by cutting to the specified length, thus obtaining a secondary finished product to meet the needs of some customers.

[0004] The aforementioned secondary processing to obtain a secondary finished product is difficult to perform in the straw blow molding equipment of this patent because it requires additional stretching and cutting devices, and also takes a considerable amount of time. Therefore, the applicant specifically designed equipment for secondary processing of straws to address this problem. Straws produced in the aforementioned blow molding equipment are collected together and then transported to the secondary processing equipment for further processing to obtain finished straws of different models. The primary finished straws produced in the aforementioned blow molding equipment will be referred to as semi-finished straws in the following text. The semi-finished product includes a tube body, a capsule body, and a variable cross-section tapered portion connecting the tube body and the capsule body. Subsequently, the tube body of the semi-finished product is stretched, causing plastic deformation and elongation of the portion of the tube body away from the capsule body. This portion is then cut to obtain a finished straw of suitable length, while the end of the tube body is removed as waste. The entire process involves three stages: stretching, cutting, and waste removal, all implemented on the applicant's newly designed processing equipment. Summary of the Invention

[0005] This invention addresses the problems of the prior art by providing a straw feeding device, comprising a vibratory feeder, a guide rail assembly connected to the vibratory feeder, and a feeding assembly and a first stopping assembly disposed above the guide rail assembly. The guide rail assembly includes two symmetrically arranged and spaced apart track plates extending in a front-to-back direction, with a sliding groove extending in the front-to-back direction formed between the two track plates. The upper part of the track plates supports the straw capsule, and the sliding groove allows the straw to enter and slide. The vibratory feeder drives the guide rail assembly to generate linear vibration. The feeding assembly includes a feeding base plate, two left and right feeding clamps slidably mounted on the feeding base plate, a clamp driving mechanism capable of driving the two feeding clamps to move towards and away from each other, and a base plate driving mechanism capable of driving the feeding base plate to move back and forth. The feeding assembly clamps the straw capsule and moves it forward. The first stopping assembly is located on the feeding assembly near the vibratory feeder and is used to stop the straw moving towards the feeding assembly.

[0006] As a preferred embodiment of the present invention, each of the two feeding clamps is provided with a bladder groove on one side facing each other, and the two feeding clamps are symmetrically arranged so that the bladder grooves on the left and right sides correspond to each other, and the bladder grooves are used to fit and abut against the straw bladder.

[0007] As a preferred embodiment of the present invention, the feeding clamp is provided with a plurality of the aforementioned grooves evenly spaced along the front-back direction, and any groove on one side corresponds to a groove on the other side.

[0008] As a preferred embodiment of the present invention, a partition is formed between any two adjacent sac grooves in the front-back direction. The front-back width of the partition gradually decreases from the part corresponding to the bottom of the sac groove to the part corresponding to the opening of the sac groove, until the part of the partition corresponding to the opening of the sac groove is a pointed edge.

[0009] As a preferred embodiment of the present invention, the feeding assembly further includes two unloading structures. Each feeding clamp is fixedly connected to an unloading structure at its front end away from the vibrating plate. The unloading structure includes an extension plate whose rear end is fixed to the feeding clamp and extends forward beyond the feeding clamp, and an unloading push plate fixed to the front end of the extension plate. The unloading push plate is upright. When the feeding clamps move away from each other, the unloading structures also move away from each other. When the feeding clamps move closer to each other, the unloading structures also move closer to each other, until the two unloading push plates abut against each other.

[0010] As a preferred embodiment of the present invention, the upper edges of the two track plates facing each other are inclined blocking surfaces, and the two blocking surfaces are symmetrical and used for the variable cross-section tapered part of the suction tube to abut.

[0011] As a preferred embodiment of the present invention, the side of the track plate is connected to an upwardly protruding limiting part, the limiting part extends in the front-back direction, the side of the limiting part facing each other is a vertical limiting surface and is connected to the upper edge of the blocking surface, and the limiting parts on both sides are used to jointly restrict the straw bag.

[0012] As a preferred embodiment of the present invention, the feeding clamp is suspended above the guide rail assembly, and a gap space is formed between the two; the first stopping assembly includes a first stopping drive mechanism and a first stopping rod connected to the first stopping drive mechanism, the first stopping rod extends in the left and right direction and is aligned with the gap space, and the first stopping drive mechanism can drive the first stopping rod to extend into and out of the gap space.

[0013] As a preferred embodiment of the present invention, a second stopping component is further provided behind the first stopping component. The second stopping component includes a second stopping drive mechanism and a second stopping rod connected to the second stopping drive mechanism. The second stopping rod extends in the left-right direction and is aligned with the interval space. The second stopping drive mechanism can drive the second stopping rod to extend into and out of the interval space. The distance between the first stopping rod and the second stopping rod is consistent with the total length of all the slots on the feeding clamp arranged in the front-back direction.

[0014] A straw processing and forming device includes the straw conveying device.

[0015] Beneficial effects:

[0016] The feeding component's forward and backward movement, as well as its final and forward positions, are pre-set. When it reaches the final position, it grips the semi-finished straws on the guide rail assembly. Then, the first stopping component removes its obstruction, allowing the feeding component to transport these straws forward onto the carrying component. Simultaneously, the feeding component reaches its forward position and releases the straws. This process then repeats continuously. The structure is simple, the principle is straightforward, and the feeding efficiency is high, requiring only the translation of the semi-finished straws. Attached Figure Description

[0030] The following specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present invention.

[0031] Example 1:

[0032] This invention discloses a straw stretching and cutting device, comprising a base 1, a platform 2 disposed on the base 1, and a support assembly 3 disposed on the platform 2; the support assembly 3 includes two support platforms 31 arranged symmetrically and spaced apart, forming a first sliding space 32 that extends vertically between the two support platforms 31; the upper side of each support platform 31 is used to prevent a straw bladder 103 from entering the first sliding space 32, and the first sliding space 32 is used to accommodate a straw tube 105; each support platform 31 has a downward-opening, horizontally extending through groove 33, and the platform 2... A positioning component 4 is provided, which can extend into the first sliding space 32 through the through groove 33 and is used to position the straw; the platform 2 has a second sliding space 21 that extends vertically and is correspondingly connected to the first sliding space 32 in the vertical direction, and the first sliding space 32 and the second sliding space 21 are used for the straw body 105 to extend into; a cutting component 6 and a stretching component 5 are provided below the platform 2, the stretching component 5 is used to stretch the straw body 105 downward, and the cutting component 6 is used to cut the straw body 105. In use, the semi-finished straw is first adjusted to a roughly vertical position with the capsule 103 on top and the tube 105 below. Then, the tube 105 of the straw is inserted from bottom to top into the first sliding space 32 between the two support platforms 31 and the second sliding space 21 on the platform 2. The first sliding space 32 is essentially a gap between the two support platforms 31, and its width is sufficient for the tube 105 to enter. However, the diameter of the capsule 103 is larger than the width of the first sliding space 32, so the capsule 103 cannot enter the first sliding space 32. Instead, it is supported by the upper sides of the two support platforms 31, thereby achieving the support of the straw by the support component 3. The tube 105 inserted into the first sliding space 32 and the second sliding space 21 is restricted by the support platforms 31 in the left and right directions, but is not restricted in the front and back directions. If the straw can sway, it cannot ensure the positional accuracy of the straw itself, affecting the subsequent stretching and cutting processes. The positioning component 4 can extend into the first sliding space 32 where the straw body 105 is located after passing through the through groove 33 on the support platform 31, and position the straw body 105 to prevent it from swaying in the front and back direction, keeping the straw body 105 in a vertical state, thereby ensuring the positional accuracy of the straw itself, ensuring the processing quality of the subsequent stretching and cutting processes, and thus ensuring the quality of the finished straw. After the lower part of the straw body 105 passes through the second sliding space 21 and extends to the bottom of the platform 2, the stretching component 5 can act on the lower part of the straw body 105, clamp it and stretch it downwards, so that the straw body 105 is stretched to the required length and then stops. Then the cutting component 6 is started to cut the straw body 105 to obtain the finished straw.The stretching and cutting device in this embodiment utilizes the structural characteristics of the semi-finished straw itself. The straw is supported by the bearing component 3, which simultaneously blocks the capsule 103, allowing the tube 105 to extend downwards. The bearing component 3 itself has a simple structure and low manufacturing cost. During feeding, the straw can be directly inserted into the first sliding space 32 of the bearing component 3, making feeding convenient. After the positioning component 4 positions the tube 105, the lower part of the tube 105 has already reached the stretching and cutting station, ensuring the positional accuracy of the straw. No additional calibration is required. The stretching component 5 and the cutting component 6 can be directly started for stretching and cutting, resulting in high processing efficiency. Moreover, the waste material cut off is the lower part of the tube 105, which falls directly downwards, making waste collection convenient. Therefore, overall, the processing accuracy is high, the processing efficiency is high, and the device cost is low.

[0033] The support component 3 supports the semi-finished straw by accommodating the tube body 105 in the first sliding space 32 and the second sliding space 21, and by supporting and blocking the capsule 103 with the two support platforms 31. As long as the tube body 105 of the semi-finished straw enters the first sliding space 32 and the second sliding space 21, it is sufficient. In this embodiment, the first sliding space 32 and the second sliding space 21 are vertically connected. Based on this, the tube body 105 of the semi-finished straw can be inserted into the first sliding space 32 and the second sliding space 21 from top to bottom. This feeding method is convenient and fast. However, the stretching and cutting device is usually a link in the straw production line. It is also extremely important to meet the requirements of assembly line feeding, which is difficult to meet with the above feeding method. Therefore, this embodiment is further improved by preferably having the first sliding space 32 and the second sliding space 21 both connected in the front-back direction and used for the back-to-back movement of the straw body 105. In this way, the straw can enter and leave the first sliding space 32 and the second sliding space 21 by being transported from back to front. The two support platforms 31 act as sliding tracks, which can be adapted to the assembly line production line. It is easier to control the quantity of each feeding during the feeding process, and it also further improves the feeding efficiency. Moreover, the semi-finished straw can be moved to the support component 3 in a basically vertical and relatively stable state, that is, the semi-finished straw on the support component 3 has determined the initial positional accuracy, which is convenient for the subsequent positioning component 4 to perform the final accurate positioning of the semi-finished straw. This greatly reduces the burden on the positioning component 4, and more importantly, it makes it unnecessary for the positioning component 4 to adopt a very complex structure, reducing the running time of the positioning component 4, improving efficiency, and reducing the manufacturing cost of the device.

[0034] Furthermore, preferably, the upper edges of the two supporting platforms 31 on opposite sides are inclined supporting surfaces 311. The two supporting surfaces 311 are symmetrical and used to abut against the variable cross-section tapered portion 104 of the straw. The two supporting surfaces 311 are used to jointly support the straw. The lateral distance between the two supporting surfaces 311 gradually increases from bottom to top, so that the two supporting surfaces 311 can simultaneously abut against the outer wall of the variable cross-section tapered portion 104 of the straw. This makes the support of the supporting platforms 31 on the straw body 103 more stable and reduces the suction... The swaying of the tube improves the positional accuracy of the straw and, on the other hand, increases the force-bearing area between the support platform 31 and the straw, thereby enhancing the blocking effect of the support platform 31 on the bladder 103 and ensuring the processing quality of the subsequent stretching process. Moreover, the variable cross-section tapered part 104 of the straw can be placed on the support surface 311 in a fit-fitting shape, which can protect the bladder 103 during the stretching process. In addition, the support surface 311 also makes it easier for the straw to slide along the support platform 31, reducing movement resistance, reducing wear of the straw during the sliding process, and making the sliding more stable.

[0035] In this embodiment, the presence of the through groove 33 on the support platform 31 allows the first sliding space 32 to communicate with the outside from both the left and right sides. The positioning component 4 also acts on the tube 105 located in the first sliding space 32 through the through groove 33. Specifically, in this embodiment, the positioning component 4 includes a left positioning seat 412 disposed on the platform 2, a left positioning drive mechanism 413 connected to the left positioning seat 412, and a plurality of left positioning strips 411 extending in the left and right directions fixed on the left positioning seat 412. One end of the left positioning strip 411 is fixed on the left positioning seat 412, and then from this fixed end... Extending to the right and suspended outside the left positioning seat 412, multiple left positioning strips 411 are evenly spaced along the front-to-back direction, and a left positioning groove 414 is formed between any two adjacent left positioning strips 411. The left positioning groove 414 is used for the straw body 105 to pass through vertically. The left positioning drive mechanism 413 can drive the left positioning seat 412 to move to the right so that the left positioning strips 411 extend into the first sliding space 32. The left positioning drive mechanism 413 can also drive the left positioning seat 412 to move to the left so that the left positioning strips 411 leave the first sliding space 32. During actual positioning, the semi-finished straw is already on the support assembly 3. The generally vertical tube 105 extends into the first sliding space 32 and the second sliding space 21. The left positioning drive mechanism 413 pushes the left positioning seat 412 to move to the right, causing the left positioning strip 411 to pass through the through groove 33 of the right support platform 31 and extend into the first sliding space 32. The left positioning strip 411 extends between two adjacent tubes 105, and the tubes 105 enter the corresponding left positioning groove 414. Each tube 105 is restricted by the two left positioning strips 411. The left positioning strips 411 keep the tubes 105 in a vertical state, thereby ensuring the overall positional accuracy of the semi-finished straw and ensuring the subsequent processing quality. Of course, the position of the left positioning bar 411 in the front-back direction is fixed, so in the initial state, the left positioning groove 414 needs to be aligned with the position of the tube body 105 in the left-right direction. This requires determining the position of the capsule 103 in the front-back direction when the semi-finished straw is transported to the carrier component 3, and then the positioning component 4 of this embodiment positions the position of the tube body 105 so that the straw is in a vertical position. This is easy to achieve for existing conveying devices.

[0036] Theoretically, if the tube body 105 of a semi-finished straw is restricted at a certain point by the left positioning strip 411, the position of its capsule 103 on the support platform 31 is also determined, thus ensuring that the semi-finished straw is vertical. However, the capsule 103 can slip on the support platform 31. If an external force is applied, the capsule 103 may slip, resulting in inaccurate positioning. Therefore, in this embodiment, the positioning component 4 preferably also includes a right positioning seat 422 disposed on the platform 2, a right positioning drive mechanism 423 connected to the right positioning seat 422, and multiple right positioning strips 42 fixed on the right positioning seat 422. 1. Multiple right positioning strips 421 are evenly spaced along the front-to-back direction, and a right positioning groove 424 is formed between any two adjacent right positioning strips 421. The right positioning groove 424 is used for the straw body 105 to pass through vertically. The right positioning drive mechanism 423 can drive the right positioning seat 422 to move to the left so that the right positioning strip 421 extends into the first sliding space 32. The right positioning drive mechanism 423 can also drive the right positioning seat 422 to move to the right so that the right positioning strip 421 leaves the first sliding space 32. The right positioning strip 421 is higher than the left positioning strip 411. The working principle of the right positioning bar 421 is the same as that of the left positioning bar 411. Both extend between adjacent tubes 105 to restrict the tubes 105. The right positioning bar 421 is higher than the left positioning bar 411. On the one hand, it ensures that the tubes 105 are stably restricted in two places in the vertical direction, ensuring that the tubes 105 remain in a vertical state. On the other hand, it ensures that the left positioning bar 411 and the right positioning bar 421 avoid each other when they extend into the first sliding space 32 at the same time. Both the left positioning strip 411 and the right positioning strip 421 extend outwards and are suspended in the air, lacking stable support. Therefore, a further improvement is made: preferably, a support plate 34 is mounted in the through groove 33 on the right side along the front-back direction. The support plate 34 has a flat upper side, and the right positioning strip 421 is attached to the upper side of the support plate 34. The left positioning strip 411 is fixed to the lower side of the left positioning seat 412 and is attached to the platform 2. In this way, the right positioning strip 421 receives auxiliary support, and the left positioning strip 411 receives auxiliary support from the platform 2, ensuring the stability of the structure of the left positioning strip 411 and the right positioning strip 421 and ensuring their positioning accuracy for the straw.

[0037] Before the positioning component 4 acts on the semi-finished straw, the semi-finished straw located on the bearing component 3 is already in a generally vertical state, but there may still be some tilt in the front-to-back direction. The function of the positioning component 4 is to eliminate these tilts. However, if the tilt is large, part of the tube body 105 is no longer aligned with the left positioning groove 414 or the right positioning groove 424 in the left-to-right direction, but is aligned with the left positioning strip 411 and the right positioning strip 421. This may cause the left positioning strip 411 and the right positioning strip 421 to fail to guide the tube body 105 into the left positioning groove 414 and the right positioning groove 424 when they act on the tube body 105, resulting in the failure to position the tube body 105. Therefore, in this embodiment, the end of the left positioning bar 411 away from the left positioning seat 412 is preferably a pointed guide portion 43 with the distance between the front and rear edges gradually decreasing from the side closer to the left positioning seat 412 to the side farther away from the left positioning seat 412. Similarly, the end of the right positioning bar 421 away from the right positioning seat 422 is also a pointed guide portion 43 with the distance between the front and rear edges gradually decreasing from the side closer to the right positioning seat 422 to the side farther away from the right positioning seat 422. In this way, the front and rear edges of the pointed guide portion 43 have a guiding effect on the tube body 105. Even if the tube body 105 is highly skewed, the pointed guide portion 43 can still guide the tube body 105 into the left positioning groove 414 and the right positioning groove 424, thereby correcting the deviation of the tube body 105 and keeping the tube body 105 in a vertical state.

[0038] In this embodiment, the stretching assembly 5 includes a stretching seat 52, a clamping mechanism 51 and a waste removal mechanism 54 disposed on the stretching seat 52, and a lifting mechanism 53 connected to the stretching seat 52 and installed below the base 1. The base 1 has a hollowed-out section corresponding to the bearing assembly 3 to allow the stretching seat 52 to move. The clamping mechanism 51 can clamp in the left and right direction, and the lifting mechanism 53 can drive the stretching seat 52 to move up and down. When the clamping mechanism 51 clamps the lower part of the tube 105, the lifting mechanism 53 drives the stretching seat 52 to move downward through the clamping mechanism 51, so that the tube 105 is stretched to the required length, thus completing the stretching. After the stretching is completed, the cutting assembly 6 will cut the tube 105, and the lower part of the tube 105 will become waste. The waste removal mechanism 54 includes a waste discharge pipe 541 located below the clamping mechanism 51. The waste discharge pipe is fixed on the stretching seat 52. The waste discharge pipe 541 has an upper inlet 542 and a lower outlet 543. The upper inlet 542 faces the clamping mechanism 51. After cutting, the waste is still clamped by the clamping mechanism 51. Then the clamping mechanism 51 is released, and the waste will automatically fall into the upper inlet 542, and after passing through the waste discharge pipe 541, it will fall out from the lower outlet 543. The waste discharge pipe 541 can limit the falling waste, prevent the waste from scattering everywhere and affecting the operation of the stretching assembly 5 and the cutting assembly 6, and also facilitate the collection of waste. The cutting assembly 6 is disposed below the platform 2 and includes a cutting drive mechanism 62 fixedly connected to the platform 2 and a cutting tool 61 connected to the cutting drive mechanism 62. The cutting drive mechanism 62 can drive the cutting tool 61 to move left and right to perform cutting.

[0039] This invention discloses a straw processing and forming device, including the straw stretching and cutting device, a conveying device connected to a supporting component 3, and the conveying device capable of directly transporting semi-finished straws from back to front onto the supporting component 3, with the capsule 103 positioned above the supporting platform 31 and the tube 105 entering the first sliding space 32. Embodiment 2 below describes a specific implementation of the conveying device.

[0040] Example 2:

[0041] The conveying device described in this embodiment is also for the aforementioned semi-finished straws, and it needs to be used in conjunction with the straw stretching and cutting device described in Embodiment 1. The conveying device needs to transport the semi-finished straws to a specific station on the carrying component 3 so that the straws can correspond to the positioning component 4. The conveying device includes a vibratory feeder 10, a guide rail assembly 7 connected to the vibratory feeder 10, and a feeding component 8 and a first stopping component 91 disposed above the guide rail assembly 7. The guide rail assembly 7 includes two symmetrically arranged and spaced apart track plates 71. The track plates 71 extend in the front-back direction, and a groove 72 extending in the front-back direction is formed between the two track plates 71. The upper part of the track plate 71 is used to support the straw capsule 103, and the groove 72 is used for the straw tube 105 to enter and slide. The semi-finished straw is in the following state on the track assembly: the capsule 103 is supported by the two track plates 71, while the tube 105 extends into the groove 72. The semi-finished straw is naturally vertical. The semi-finished straws also need to be in a vertical position, so the guide rail assembly 7 only needs to move the semi-finished straws forward and transport them to the bearing assembly 3, without needing to make additional adjustments to the posture of the semi-finished straws; the vibratory plate 10 is a commonly used feeding device, which is connected to the guide rail assembly 7 and can drive the guide rail assembly 7 to generate linear vibration. Therefore, the vibratory plate 10 can not only transport the semi-finished straws piled up inside it in an orderly manner to the guide rail assembly 7, but also enable the guide rail assembly 7 to drive the semi-finished straws to move forward along the track plate 71 through linear vibration.The guide rail assembly 7 can transport semi-finished straws towards the carrier assembly 3. Pushing the semi-finished straws to a specific position on the carrier assembly 3 also requires the feeding assembly 8. The feeding assembly 8 includes a feeding base plate 81, two left and right feeding clamping plates 82 slidably mounted on the feeding base plate 81, a clamping plate driving mechanism 83 capable of driving the two feeding clamping plates 82 to move towards and away from each other, and a base plate driving mechanism 84 capable of driving the feeding base plate 81 to move back and forth. The feeding assembly 8 is used to clamp the straw capsule 103 and drive it forward. The first stopping assembly 91 is located on the feeding assembly 8 near the vibrating plate 10 and is used to stop the straws moving towards the feeding assembly 8. The first stopping assembly 91 can stop multiple continuously moving semi-finished straws on the guide rail assembly 7 at a specific position, and then allow the feeding assembly 8 to clamp and transport the first batch of semi-finished straws. The stopping component 91 ensures that the quantity and initial position of each batch of semi-finished straws transported by the feeding component 8 are determined. This ensures that the quantity and position of each batch of semi-finished straws after being transported to the carrying component 3 by the feeding component 8 are also fixed, guaranteeing that the semi-finished straws accurately reach their designated positions on the carrying component 3, facilitating subsequent processing. The travel distance, final position, and foremost position of the feeding component 8 in the forward-backward direction are all pre-set. When it reaches the final position, it clamps the semi-finished straws on the guide rail component 7. Then, the first stopping component 91 removes its obstruction of the semi-finished straws, and the feeding component 8 transports these semi-finished straws forward to the carrying component 3. Simultaneously, the feeding component 8 reaches its foremost position and releases the semi-finished straws. The next feeding cycle then begins, repeating the process. The structure is simple, the principle is straightforward, and the feeding efficiency is very high, requiring only the translation of the semi-finished straws.

[0042] The feeding component 8 clamps the capsule 103 of the semi-finished straw. If the two feeding clamps 82 are flat on one side, the capsule 103 usually needs to be flattened to obtain sufficient friction to ensure a stable clamping. However, the semi-finished straws that are stopped by the first stopping component 91 are closely arranged together in the front-back direction. Once the capsule 103 is flattened, the adjacent capsules 103 will be squeezed and misaligned in the front-back direction, affecting the positional accuracy. Moreover, the quality of the capsule 103 itself may also be affected. Therefore, in this embodiment, both feeding clamps 82 are provided with a bladder groove 821 facing each other. The two feeding clamps 82 are symmetrically arranged so that the bladder grooves 821 on the left and right sides correspond to each other. The bladder grooves 821 are used to cooperate and abut with the straw bladder 103. When the feeding clamps 82 move towards each other to clamp the semi-finished straw, the bladder 103 enters the bladder groove 821. The two bladder grooves 821 together surround the bladder 103. Since the front and back sides of the bladder 103 are also blocked by the groove walls of the bladder grooves 821, the forward movement of the bladder 103 can be directly inferred from the structure. In fact, it is not necessary to rely on the friction force obtained by clamping the bladder 103 in the left and right directions. It is enough to just surround it. This not only can the position of the bladder 103 be accurately limited, but also the reliability of moving the bladder 103 is high, and it will not have an adverse effect on the bladder 103 itself. In this embodiment, the feeding clamp 82 is provided with a plurality of bladder grooves 821 evenly spaced along the front-to-back direction. Any bladder groove 821 on one side corresponds approximately to a bladder groove 821 on the other side, so that multiple semi-finished straws can be fed at a time, improving feeding efficiency. The bladder body 103 of the semi-finished straw is cylindrical, and the shape of the bladder groove 821 corresponds to and matches the bladder body 103, and is an arc-shaped groove.

[0043] The feeding clamp 82 has multiple slots 821, and there is a natural solid structure, namely a partition 822, between any two adjacent slots 821. Since the semi-finished straws stopped by the first stopping component 91 still tend to move forward under the linear vibration of the guide rail assembly 7, these semi-finished straws are closely packed together in a row, with almost no gap between adjacent bladders 103. When the two feeding clamps 82 hold the semi-finished straws, the partition 822 needs to extend into the adjacent bladders. The two sacs 103 are positioned so that they can enter the sac grooves 821. The partition 822 is formed by the opening of the sac grooves 821. Therefore, in the left-right direction, the partition 822 extends from the bottom of the corresponding sac groove 821 to the opening of the corresponding sac groove 821. If the partition 822 is to be able to extend between the adjacent sacs 103 and separate them, the width of the partition 822 at the opening of the corresponding sac groove 821 in the front-back direction cannot be too large, otherwise the adjacent sacs 103 cannot be separated. In this embodiment, the width of the partition portion 822 gradually decreases from the bottom of the groove 821 to the opening of the groove 821, until the part of the partition portion 822 corresponding to the opening of the groove 821 is a pointed edge 823. This ensures that the partition portion 822 can extend between adjacent bladders 103 and separate them, ensuring that the bladders 103 can smoothly enter the corresponding groove 821 and ensuring the positional accuracy of the bladders 103, thereby ensuring the overall positional accuracy of the semi-finished straw.

[0044] After the semi-finished straws on the carrier component 3 have been processed, the feeding component 8 needs to transport the next batch of semi-finished straws from the guide rail component 7 to the carrier component 3 for processing. However, before that, the finished straws obtained after processing need to be unloaded from the carrier component 3 to make room for the next batch of semi-finished straws. This is actually a way of transporting the finished straws. In this preferred embodiment, the feeding assembly 8 further includes two unloading structures 85. Each feeding clamp 82 is fixedly connected to an unloading structure 85 at its front end away from the vibrating plate 10. The unloading structure 85 includes an extension plate 851 whose rear end is fixed to the feeding clamp 82 and extends forward beyond the feeding clamp 82, and an unloading push plate 852 fixed to the front end of the extension plate 851. The unloading push plate 852 is upright. When the feeding clamps 82 move away from each other, the unloading structures 85 also move away from each other. When the feeding clamps 82 move closer to each other, the unloading structures 85 also move closer to each other until the two unloading push plates 852 abut against each other. When the semi-finished straws on the bearing component 3 are processed into finished straws, and the feeding component 8 moves backward above the guide rail component 7 to clamp the next batch of semi-finished straws, the feeding clamping plates 82 approach each other until they complete clamping of the capsule 103. At the same time, the two unloading structures 85 also approach each other until they abut against each other through the unloading push plate 852. The unloading push plate 852 is upright, and the two unloading push plates 852 abut against each other to form a whole. Then the feeding clamping plate 82 moves the clamped semi-finished straws forward, and the unloading push plate 852 moves along with it and moves first to the top. Above the bearing assembly 3, the unloading push plate 852 is aligned with the capsule 103 of the finished straw on the bearing assembly 3. During the subsequent movement, the unloading push plate 852 pushes the finished straw on the bearing assembly 3 forward away from the bearing assembly 3. Then, the loading clamp plate 82 transports a new batch of semi-finished straws to the bearing assembly 3. Therefore, the loading assembly 8 can simultaneously realize the unloading and loading of the bearing assembly 3 without the need for an additional unloading device, which reduces equipment costs, reduces the special unloading process, reduces the total loading and unloading time, and effectively improves the conveying efficiency of the straws.

[0045] The guide rail assembly 7 supports the semi-finished straw through two track plates 71. To improve the stability of the support, it is preferable that the upper edges of the two track plates 71 facing each other are inclined blocking surfaces 711. The two blocking surfaces 711 are symmetrical and are used for the variable cross-section tapered portion 104 of the straw to abut against. This can increase the contact area between the track plates 71 and the semi-finished straw. At the same time, by utilizing the shape characteristics of the variable cross-section tapered portion 104 between the capsule 103 and the tube 105, the swaying of the semi-finished straw in the left and right direction is reduced, and the support stability of the guide rail assembly 7 for the semi-finished straw is improved. In the front and back direction, the semi-finished straw has a tendency to move forward. The first stopping component 91 blocks the capsule 103. This tension can reduce the tilt of the capsule 103 in the front and back direction, so that the semi-finished straw is in a roughly vertical state. This makes it easier for the capsule 103 to enter the capsule groove 821 when the subsequent feeding clamp 82 clamps the semi-finished straw, ensuring the clamping effect. In a further improvement, the upper side of the track plate 71 is preferably connected to an upwardly protruding limiting part 73. The limiting part 73 extends in the front-back direction. The side of the limiting part 73 facing each other is a vertical limiting surface 731 and is connected to the upper edge of the blocking surface 711. The limiting parts 73 on both sides are used to jointly restrict the straw bag 103. By having the limiting surface 731 abut against the outer wall of the bag 103, the bag 103 is restricted from the left and right sides, which further improves the stability of the bag 103 on the guide rail assembly 7, thereby improving the positional accuracy of the bag 103.

[0046] In this embodiment, the feeding clamp 82 is suspended above the guide rail assembly 7, and a gap space 101 is formed between the two. This can prevent the feeding clamp 82 from contacting the guide rail assembly 7, reduce the moving resistance of the feeding clamp 82, reduce the cost of the power mechanism, and also prevent wear. On the other hand, it provides clearance space for the first stopping mechanism. The first stopping component 91 includes a first stopping drive mechanism 912 and a first stopping rod 911 connected to the first stopping drive mechanism 912. The first stopping rod 911 extends in the left-right direction and is aligned with the interval space 101. The first stopping drive mechanism 912 can drive the first stopping rod 911 to extend into and out of the interval space 101. When it is necessary to stop the semi-finished straw, the first stopping drive mechanism 912 is activated to drive the first stopping rod 911 into the interval space 101 until it blocks the semi-finished straw. At this time, the first stopping rod 911 will not affect the forward and backward movement of the feeding clamp 82. When it is necessary to remove the stop on the semi-finished straw, the first stopping drive mechanism 912 is activated to drive the first stopping rod 911 to be pulled out of the interval space 101. In this way, the semi-finished straw is no longer blocked by the first stopping rod 911, and the feeding clamp 82 can drive the semi-finished straw to move forward.

[0047] After the first stop bar 911 is pulled out of the interval space 101, the feeding clamp 82 takes away the first batch of semi-finished straws. At the same time, the semi-finished straws behind will immediately move forward under the linear vibration of the guide rail assembly 7, thus filling the position of the original batch of semi-finished straws. However, at this time, the first stop bar 911 may not have had time to re-enter the interval space 101 to block, which will cause some semi-finished straws to cross the position of the first stop bar 911. These straws cannot be clamped as the next batch of straws. Therefore, this embodiment preferably also includes a second stop component 92 disposed behind the first stop component 91. The second stop component 92 includes a second stop drive mechanism 922 and a second stop rod 921 connected to the second stop drive mechanism 922. The second stop rod 921 extends in the left-right direction and is aligned with the interval space 101. The second stop drive mechanism 922 can drive the second stop rod 921 to extend into and out of the interval space 101. The distance between the first stop rod 911 and the second stop rod 921 is consistent with the total length of all the slots 821 on the feeding clamp 82 arranged in the front-back direction. On the one hand, the second stopping mechanism can block the semi-finished straws queuing behind it before the first stopping mechanism returns to its original position. The semi-finished straws will only be released after the first stopping rod 911 in the first stopping mechanism re-enters the interval space 101, ensuring that the next batch of semi-finished straws is blocked by the first stopping mechanism. On the other hand, the distance between the first stopping rod 911 and the second stopping rod 921 is consistent with the total length of all the slots 821 on the feeding clamp 82 in the front-to-back direction. This ensures that all the semi-finished straws queuing between the first stopping rod 911 and the second stopping rod 921 are transported away by the feeding component 8 as part of the same batch. This precisely controls the number of semi-finished straws during each feeding, ensuring that each slot 821 on the feeding clamp 82 corresponds to the body 103 of a semi-finished straw, improving utilization and feeding efficiency. It also prevents any semi-finished straws from being missed between the first stopping rod 911 and the second stopping rod 921. In this embodiment, there is only one partition 822 behind the last bladder groove 821 on the feeding clamp 82, so that the semi-finished straw blocked behind the second stop bar 921 will not be affected when clamping.

The bearing component 3 is connected to the guide rail component 7 front and rear, and the first sliding space 32 and the second sliding space 21 are both connected to the slide groove 72 in the guide rail component 7 front and rear.
