Description

Technical Field

[0001] This utility model relates to the field of needle processing technology, specifically to a needle synchronous feeding mechanism. Background Technology

[0002] Acupuncture needles are quite small. In the packaging process, acupuncture needles need to be first put into plastic tubes to form a tube needle, and then further packaging and other processing are carried out.

[0003] To assemble the acupuncture needle, the acupuncture needle and the plastic tube need to be fed separately, and then assembled on the subsequent receiving device. Considering that the two are prone to tilting during the placement of the two on the receiving device, any tilting of either one will prevent them from being assembled immediately, affecting the assembly progress of the acupuncture needle.

[0004] Acupuncture needles and plastic tubes are typically fed using two separate feeding devices. However, these two feeding devices can easily affect the overall structural layout of the entire needle processing device. When either feeding device malfunctions, in addition to repairing the faulty device, the other feeding device usually also needs to be inspected to reduce risk. The shortcomings of the aforementioned existing technology include:

[0005] 1. Because the two sets of feeding devices are set up separately, it is difficult to operate the two sets of feeding devices simultaneously, which will affect the progress of maintenance and inspection.

[0006] Second, the separate setup of the two feeding devices will make it difficult for the overall layout of the equipment to meet the compact requirements and will occupy too much equipment space.

[0007] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0008] The purpose of this invention is to provide a synchronous feeding mechanism for tube needles.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] A simultaneous feeding mechanism for acupuncture needles and plastic tubes is provided. The simultaneous feeding mechanism includes a lifting component, a needle feeding component, and a tube feeding component.

[0011] The lifting assembly includes a lifting body and a lifting platform installed on the lifting body; the lifting body serves as a component for driving the lifting platform to move vertically.

[0012] The needle arrangement assembly includes a support platform, a needle arrangement wheel, and a needle arrangement wheel drive component; the needle arrangement wheel drive component is connected to the support platform and serves as a component for driving the needle arrangement wheel to rotate; the needle arrangement wheel is provided with a plurality of needle arrangement grooves that are evenly distributed in a circle around the axis of the needle arrangement wheel and are parallel to each other.

[0013] The pipe-laying assembly includes a support base, a pipe-laying wheel, and a pipe-laying wheel drive component; the pipe-laying wheel drive component is connected to the support base and serves as a component for driving the pipe-laying wheel to rotate; the pipe-laying wheel is provided with a plurality of pipe-laying grooves that are uniformly distributed in a circle around the axis of the pipe-laying wheel and are parallel to each other.

[0014] In the above scheme, the needle-arranging assembly and the tube-arranging assembly are used to complete the feeding operation of acupuncture needles and plastic tubes, respectively. The feeding process can be carried out manually or by other existing devices. The feeding process of both is the same. The following description takes the feeding process of acupuncture needles as an example: In one specific method, acupuncture needles are placed on a support platform. Several acupuncture needles are arranged in parallel on the top of the support platform. Each acupuncture needle is pushed into the needle-arranging groove on the needle-arranging wheel in sequence. With the help of the driving component of the needle-arranging wheel, the needle-arranging wheel turns the acupuncture needles into the subsequent processing device.

[0015] By using the needle assembly and tube assembly, the feeding of each acupuncture needle and each plastic tube can be distributed, avoiding their accumulation and obstruction of subsequent processing. It also allows the acupuncture needle and plastic tube to enter the subsequent processing device in a predetermined direction, providing convenience for subsequent processing.

[0016] Taking the needle-laying groove as an example, the same applies to the tube-laying groove: the needle-laying groove is evenly distributed in a circle around the axis of the needle-laying wheel, which further ensures the orderly feeding of acupuncture needles and provides further convenience for subsequent processing.

[0017] The extension direction of each tube groove is the same as that of each needle groove, ensuring that the acupuncture needles and plastic tubes enter the subsequent processing device in the same direction, further facilitating subsequent processing.

[0018] With the help of the lifting assembly, when any structure of either the pin assembly or the tube assembly malfunctions, both can be quickly and synchronously moved vertically to leave the designated feeding area for maintenance or inspection.

[0019] Compared to the arrangement where the needle tray assembly and tube tray assembly are spaced apart, placing both assemblies on the lifting platform facilitates better overall structural layout of the feeding mechanism and allows for simultaneous transfer of both, enabling convenient maintenance or inspection of both. It's important to emphasize that even if only one assembly malfunctions, considering their structural and operational similarities, there is a need to inspect the other. Furthermore, given their interoperability, continuing the feeding operation of the other while one malfunctions is impractical.

[0020] In a further technical solution, the number of needle slots is the same as the number of tube slots.

[0021] The settings in this section further ensure the orderly feeding of acupuncture needles and plastic tubes, making it easier for the two to be matched one by one.

[0022] In a further technical solution, the pin header assembly also includes a coarse dividing wheel and a coarse dividing wheel drive connected to each other; the coarse dividing wheel drive is connected to the support platform and serves as a component for driving the coarse dividing wheel to rotate; the coarse dividing wheel is provided with a plurality of coarse dividing grooves that are evenly distributed in a circle around the axis of the coarse dividing wheel.

[0023] The extension direction of each of the coarse dividing grooves is the same as the extension direction of each of the pin packing grooves;

[0024] The size of the coarse dividing groove is larger than the size of the needle row groove.

[0025] Considering the thin nature of acupuncture needles, if the needles are fed too quickly and accumulate on one side of the needle-laying wheel, the wheel may push some needles to tilt during rotation, making it difficult for them to enter the needle-laying slots. Even if they do enter, the probability of two needles entering a single slot increases. By using a coarse-dividing wheel to transfer the needles to the needle-laying wheel, the needles are ensured to move towards the wheel in an orderly manner, thus avoiding the above phenomenon.

[0026] In a further technical solution, the needle array assembly also includes a connected upper needle belt and an upper needle belt drive;

[0027] The upper needle belt drive is connected to the support platform and serves as a component for driving the upper needle belt to move.

[0028] The upper needle belt serves as a component for conveying the acupuncture needles along a first predetermined path;

[0029] The direction of the first predetermined path is perpendicular to the extension direction of the needle groove.

[0030] The upper needle belt is used in conjunction with the needle row wheel or the needle row wheel and the coarse dividing wheel. By placing a large number of acupuncture needles onto the upper needle belt at once, it avoids the need to repeatedly remove acupuncture needles from the needle loading structure. It also makes it easier to pre-adjust the orientation of the acupuncture needles before they enter the needle row groove or the coarse dividing groove.

[0031] The direction of the first predetermined path is perpendicular to the extension direction of the needle slot, which facilitates the entry of acupuncture needles into the needle slot or coarse groove.

[0032] In a further technical solution, the needle assembly also includes a needle divider connected to the support platform, the needle divider serving as a component for adjusting the acupuncture needles.

[0033] In some embodiments, the needle-dispensing component includes a needle-dispensing cylinder and a nylon block connected together. The needle-dispensing cylinder drives the nylon block to reciprocate vertically. Taking the upper needle belt in conjunction with the coarse dispensing wheel as an example, the nylon block can intermittently prevent the acupuncture needle from approaching the coarse dispensing wheel. The nylon block can also press down the acupuncture needle, reduce the amount of acupuncture needle accumulation on one side of the coarse dispensing wheel, and reduce the tilt rate of the acupuncture needle.

[0034] In a further technical solution, the needle assembly also includes a brush and a brush drive connected together; the brush drive is connected to the support platform and serves as a component for driving the brush to rotate; the brush serves as a component for limiting the number of acupuncture needles accommodated in the tube slot.

[0035] And / or, the needle assembly further includes a needle guard connected to the support platform, the needle guard serving as a component to prevent the acupuncture needle from prematurely separating from the needle slot before entering a predetermined area.

[0036] Considering that if a single needle slot accommodates multiple acupuncture needles, some needles may become misaligned due to mutual collisions during subsequent feeding, and the feeding process may be slow, in some embodiments, a single needle slot can only fully accommodate a single acupuncture needle. When there are two acupuncture needles in a single needle slot, part of one of them protrudes from the needle slot. In this case, a rotating brush can remove the protruding acupuncture needle from the needle slot, ensuring feeding efficiency and preventing the acupuncture needle from becoming misaligned.

[0037] Before being unloaded, acupuncture needles are prone to separating from the needle slot due to gravity. The needle guard prevents this problem.

[0038] In a further technical solution, the needle insertion assembly further includes a first vacuum adsorption component, at least a portion of which is mounted on the support platform. The first vacuum adsorption component serves as a component for facilitating the acupuncture needles to enter the needle insertion groove and preventing the acupuncture needles from easily separating from the needle insertion groove.

[0039] And / or, the pipe assembly further includes a second vacuum suction member, at least a portion of which is mounted on the support base, the second vacuum suction member serving as a component for facilitating the plastic pipe into the pipe groove and preventing the plastic pipe from easily separating from the pipe groove.

[0040] The first vacuum adsorption member is described in the following description, and the second vacuum adsorption member is described in the same way: In some embodiments, the inner space of the needle slot is connected to the inner space of the needle wheel, and the first vacuum adsorption member causes the acupuncture needle to enter the needle slot by adjusting the pressure of the inner space of the needle wheel.

[0041] Similar to the needle guard, the first vacuum suction device also prevents the acupuncture needle from separating from the needle slot before entering the predetermined area.

[0042] In a further technical solution, the needle-rowing assembly also includes a first detection sensor disposed above the support platform; the first detection sensor serves as a component for detecting the number of acupuncture needles in the area between the coarse dividing wheel and the needle-rowing wheel.

[0043] In some embodiments, the coarse sorting wheel only operates when the number of acupuncture needles detected by the first detection sensor is small (e.g., zero), to avoid the aforementioned problems such as needle misalignment caused by needle accumulation.

[0044] In a further technical solution, the pipe assembly also includes an upper pipe belt and an upper pipe belt drive component;

[0045] The upper tube belt drive component is connected to the support base and serves as a component for driving the upper tube belt to move.

[0046] The upper tube belt serves as a component for conveying the plastic tube along a second predetermined path;

[0047] The direction of the second predetermined path is perpendicular to the extension direction of the pipe trench.

[0048] The upper pipe belt is used in conjunction with the pipe-laying wheel. By placing a large number of plastic pipes onto the upper pipe belt at once, it avoids the need to repeatedly remove the plastic pipes from the structure that loads them. It also makes it easier to pre-adjust the orientation of the plastic pipes before they enter the pipe-laying trough.

[0049] The direction of the second predetermined path is perpendicular to the extension direction of the pipe trench, which facilitates the entry of the plastic pipe into the pipe trench.

[0050] In a further technical solution, the pipe assembly also includes a second detection sensor disposed above the support base; the second detection sensor serves as a component for detecting the number of plastic pipes in the area between the upper pipe belt and the pipe wheel.

[0051] In some embodiments, the upper conveyor belt only runs when the number of plastic tubes detected by the second detection sensor is small (e.g., zero), to avoid the aforementioned problems such as plastic tube skewing caused by plastic tube accumulation.

[0055] Unless otherwise specified, the terms used herein generally have their ordinary meaning in the context of the art, the subject matter, and the specific context. Certain terms used to describe this case will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the case.

[0056] The terms “front,” “back,” “up,” “down,” “left,” and “right” used in this article are directional terms.

[0057] The working principle and advantages of this utility model are as follows: The needle-arranging assembly and the tube-arranging assembly are used to complete the feeding operation of acupuncture needles and plastic tubes, respectively. The feeding process can be carried out manually or by other existing devices. The feeding process of both is the same. The following description takes the feeding process of acupuncture needles as an example: In one specific method, acupuncture needles are placed on a support platform, and several acupuncture needles are arranged in parallel on the top of the support platform. Each acupuncture needle is pushed into the needle-arranging groove on the needle-arranging wheel in sequence. Driven by the needle-arranging wheel drive, the needle-arranging wheel rotates the acupuncture needles into the subsequent processing device. With the help of the needle-arranging assembly and the tube-arranging assembly, the feeding of each acupuncture needle and each plastic tube can be realized in a decentralized manner, avoiding the accumulation of the two and hindering the processing of the two by the subsequent processing device. It also allows the acupuncture needles and plastic tubes to enter the subsequent processing device in a predetermined direction, providing convenience for subsequent processing. With the help of the lifting component, when any structure of either the pin assembly or the tube assembly malfunctions, both can be quickly moved vertically and synchronously to leave the predetermined feeding area for maintenance or inspection, thus ensuring the progress of maintenance and inspection. At the same time, the pin assembly and the tube assembly are set close to or adjacent to each other, which not only meets the requirements of structural compactness and avoids the impact of the overall structural layout of the entire tube and pin processing device on the scattered arrangement of the two, but also provides convenience for simultaneous inspection of the two.

[0068] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0069] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0070] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.

[0071] See Figures 1-9 A needle-tube synchronous feeding mechanism for acupuncture needles 1 and plastic tubes 2, the needle-tube synchronous feeding mechanism includes a lifting component 3, a needle-rowing component 4 and a tube-rowing component 5;

[0072] The lifting assembly 3 includes a lifting body 31 and a lifting platform 32 installed on the lifting body 31; the lifting body 31 serves as a component for driving the lifting platform 32 to move vertically.

[0073] The needle arrangement assembly 4 includes a support platform 41, a needle arrangement wheel 42, and a needle arrangement wheel drive 43; the needle arrangement wheel drive 43 is connected to the support platform 41 and serves as a component for driving the needle arrangement wheel 42 to rotate; the needle arrangement wheel 42 is provided with a plurality of needle arrangement grooves 421 that are evenly distributed in a circle around the axis of the needle arrangement wheel 42 and are parallel to each other.

[0074] The pipe arrangement assembly 5 includes a support base 51, a pipe arrangement wheel 52, and a pipe arrangement wheel drive component 53; the pipe arrangement wheel drive component 53 is connected to the support base 51 and serves as a component for driving the pipe arrangement wheel 52 to rotate; the pipe arrangement wheel 52 is provided with a plurality of pipe arrangement grooves 521 that are evenly distributed in a circle around the axis of the pipe arrangement wheel 52 and are parallel to each other.

[0075] In some embodiments, the extension direction of each tube groove 521 is the same as the extension direction of each needle groove 421, ensuring that the acupuncture needle 1 and the plastic tube 2 enter the subsequent processing device in the same orientation, further facilitating subsequent processing.

[0076] At least one of the support platform 41 and the support base 51 is connected to the lifting platform 32. For example, the support platform 41 is connected to the lifting platform 32, and the support base 51 is connected to the support platform 41.

[0077] In some embodiments, the support platform 41 and the support base 51 are fitted together in the horizontal direction to better meet the requirements of structural compactness.

[0078] It should be noted that this application can be used for components to be loaded other than the acupuncture needle 1 and the plastic tube 2 (or tube sleeve).

[0079] In some embodiments, the lifting body 31 has an adjusting handwheel 311, which can be rotated to move the lifting platform 32 vertically.

[0080] In some embodiments, the lifting assembly 3 is configured as a manual screw jack. In other embodiments, the lifting body 31 of the lifting assembly 3 may also be configured as an existing device such as a linear motor or a cylinder.

[0081] The needle assembly 4 and the tube assembly 5 are used to complete the feeding operation of the acupuncture needle 1 and the plastic tube 2, respectively. The feeding process can be carried out manually or by other existing devices. The feeding process of both is the same. The feeding process of the acupuncture needle 1 is described below as an example: In one specific method, the acupuncture needle 1 is placed on the support platform 41. Several acupuncture needles 1 are arranged in parallel on the top of the support platform 41. Each acupuncture needle 1 is pushed into the needle slot 421 on the needle wheel 42 in sequence. With the help of the needle wheel drive 43, the needle wheel 42 rotates the acupuncture needle 1 into the subsequent processing device.

[0082] In some embodiments, the pinwheel drive 43 and the tube wheel drive 53 are configured as drive motors.

[0083] With the help of the needle assembly 4 and the tube assembly 5, the feeding of each acupuncture needle 1 and each plastic tube 2 can be distributed, avoiding the accumulation of the two and hindering the subsequent processing device from processing them. It also allows the acupuncture needle 1 and the plastic tube 2 to enter the subsequent processing device in a predetermined direction, which facilitates the subsequent processing.

[0084] Taking the needle groove 421 as an example, the tube groove 521 is explained in the same way: the needle groove 421 is evenly distributed in a circle around the axis of the needle wheel 42, which further ensures the orderly feeding of the acupuncture needle 1 and further facilitates subsequent processing.

[0085] With the help of the lifting component 3, when any structure of either the pin assembly 4 or the tube assembly 5 malfunctions, both can be quickly and synchronously moved vertically to leave the designated feeding area for maintenance or inspection. This avoids other processing and coordination devices affecting maintenance personnel's maintenance or inspection of the pin assembly 4 and tube assembly 5, and also avoids factors such as maintenance personnel running between the pin assembly 4 and tube assembly 5 affecting the progress of maintenance or inspection. This ensures the progress of maintenance or inspection while avoiding the impact of the overall structural layout of the entire tube needle processing device due to the dispersed arrangement of the two components.

[0086] Compared to the arrangement where the needle array assembly 4 and the tube array assembly 5 are spaced apart, the needle array assembly 4 and the tube array assembly 5 are both located on the lifting platform 32, close to or adjacent to each other. This arrangement facilitates the overall structural layout of the feeding mechanism and allows for simultaneous transfer of both components, making it convenient to inspect or maintain both. It is important to emphasize that even if only one of the needle array assembly 4 or the tube array assembly 5 malfunctions, considering their structural and operational similarities, there is a need to inspect the other. Furthermore, given that they are used in conjunction, continuing the feeding operation of the other when one malfunctions is practically meaningless.

[0087] It should be emphasized that the pin wheel drive 43 and the tube wheel drive 53 can be two independent drive devices or the same drive device, that is, the pin wheel 42 and the tube wheel 43 can be driven synchronously by a single drive device.

[0088] In this embodiment, the axis of the needle roller 42 has an angle with the horizontal direction.

[0089] In some embodiments, the angle between the axis of the pinwheel 42 and the horizontal direction is set to 5 degrees.

[0090] Specifically, the end of the needle-rowing wheel 42 near the tube-rowing wheel 52 is tilted downwards, so that the needle handle of the acupuncture needle 1 is as close as possible to the plastic tube 2, which facilitates the subsequent assembly of the two.

[0091] In some embodiments, the tilting of the pinwheel 42 is achieved by the tilting of the support platform 41.

[0092] In this embodiment, the number of needle slots 421 is the same as the number of tube slots 521.

[0093] The arrangement in this embodiment further ensures the orderly feeding of acupuncture needles 1 and plastic tubes 2, making it easier for the two to be matched one by one.

[0094] See Figure 5 In this embodiment, the pin assembly 4 further includes a coarse dividing wheel 44 and a coarse dividing wheel drive 45 connected to each other; the coarse dividing wheel drive 45 is connected to the support platform 41 and serves as a component for driving the coarse dividing wheel 44 to rotate; the coarse dividing wheel 44 is provided with a plurality of coarse dividing grooves 441 that are evenly distributed in a circle around the axis of the coarse dividing wheel 44.

[0095] The extending direction of each of the coarse dividing grooves 441 is the same as the extending direction of each of the pin row grooves 421;

[0096] The size (width) of the coarse dividing groove 441 is larger than the size (width) of the pin row groove 421.

[0097] In some embodiments, the coarse dividing wheel drive 45 is configured as a drive motor.

[0098] The coarse dividing wheel 44 is used in conjunction with the needle row wheel 42. Based on this, in this embodiment, the extension direction of each coarse dividing groove 441 is the same as the extension direction of each needle row groove 421.

[0099] The size of the coarse groove 441 is larger than that of the needle row groove 421. Based on this, the coarse groove 441 can accommodate more acupuncture needles 1 compared to the needle row groove 421. Generally, the size of the acupuncture needles 1 varies, and the needle row groove 421 is designed to be appropriately larger to accommodate acupuncture needles 1 of different specifications. However, it is generally limited to fully accommodating only one acupuncture needle 1, while the coarse groove 441 can generally fully accommodate at least two acupuncture needles 1.

[0100] Considering the thinness of the acupuncture needle 1, if the acupuncture needle 1 is fed quickly and accumulates on one side of the needle-rowing wheel 42, the needle-rowing wheel 42 may push some acupuncture needle 1 to tilt during rotation, making it difficult for the acupuncture needle 1 to enter the needle-rowing groove 421. Even if it does enter, it will increase the probability of two acupuncture needle 1 entering a single needle-rowing groove 421. However, by using the coarse dividing wheel 44 to transfer the acupuncture needle 1 to the needle-rowing wheel 42, it is ensured that each acupuncture needle 1 moves towards the needle-rowing wheel 42 in an orderly manner, thus avoiding the above phenomenon.

[0101] See Figure 4 , Figure 5 In this embodiment, the needle assembly 4 further includes an upper needle belt 46 and an upper needle belt drive 47 connected to each other;

[0102] The upper needle belt drive 47 is connected to the support platform 41 and serves as a component for driving the upper needle belt 46 to move.

[0103] The upper needle belt 46 serves as a component for conveying the acupuncture needle 1 along a first predetermined path;

[0104] The direction of the first predetermined path is perpendicular to the extension direction of the needle groove 421.

[0105] In some embodiments, the upper needle belt drive 47 is configured as a drive motor.

[0106] In some embodiments, the upper needle belt 46 and the upper needle belt drive 47 constitute a conventional belt conveyor.

[0107] The upper needle belt 46 is used in conjunction with the needle row wheel 42 or the needle row wheel 42 and the coarse dividing wheel 44. By placing a large number of acupuncture needles 1 onto the upper needle belt 46 at once, it avoids the need to repeatedly remove the acupuncture needles 1 from the structure that holds the acupuncture needles 1. It also makes it easier to pre-adjust the orientation of the acupuncture needles 1 before they enter the needle row groove 421 or the coarse dividing groove 441.

[0108] The direction of the first predetermined path is perpendicular to the extension direction of the needle groove 421, which facilitates the entry of the acupuncture needle 1 into the needle groove 421 or the coarse groove 441.

[0109] See Figure 5 , Figure 6In this embodiment, the needle assembly 4 further includes a needle-separating component 48 connected to the support platform 41, the needle-separating component 48 serving as a component for adjusting the acupuncture needle 1.

[0110] In some embodiments, the needle-distributing component 48 includes a needle-distributing cylinder and a nylon block connected together. The needle-distributing cylinder drives the nylon block to reciprocate vertically. Taking the upper needle belt 46 in conjunction with the coarse dividing wheel 44 as an example, in some cases, the nylon block can intermittently prevent the acupuncture needle 1 from approaching the coarse dividing wheel 44, reducing the amount of acupuncture needle 1 accumulating on one side of the coarse dividing wheel 44; in other cases, the nylon block can straighten the tilted acupuncture needle 1, reducing the workload of the operator.

[0111] See Figure 1 , Figure 6 In this embodiment, the needle assembly 4 further includes a brush 49 and a brush drive 401 connected together; the brush drive 401 is connected to the support platform 41 and serves as a component for driving the brush 49 to rotate; the brush 49 serves as a component for limiting the number of acupuncture needles 1 accommodated in the tube groove 521.

[0112] And / or, the needle assembly 4 further includes a needle guard 402 connected to the support platform 41, the needle guard 402 serving as a component for preventing the acupuncture needle 1 from separating prematurely from the needle groove 421 before entering the predetermined area.

[0113] In some embodiments, the brush drive 401 is configured as a drive motor.

[0114] Considering that if a single needle slot 421 accommodates multiple acupuncture needles 1, some acupuncture needles 1 may easily become misaligned due to mutual collisions or other reasons during subsequent feeding, and the feeding process may be slow, in some embodiments, a single needle slot 421 can only fully accommodate a single acupuncture needle 1. When there are two acupuncture needles 1 in a single needle slot 421, part of one of them protrudes out of the needle slot 421. At this time, the protruding acupuncture needle 1 can be moved out of the needle slot 421 by rotating the brush 49, so as to ensure feeding efficiency and avoid misalignment of the acupuncture needle 1.

[0115] In some embodiments, the needle guard 402 is configured as an arc-shaped structure and fits or is close to the outer surface of the needle roller 42.

[0116] In some embodiments, the needle guard 402 is also used to limit the number of acupuncture needles 1 contained in the tube slot 521.

[0117] In some embodiments, the needle protector 402 is configured as a needle protector block.

[0118] In some embodiments, the needle guard 402 is configured as an elastic belt.

[0119] Before the acupuncture needle 1 is unloaded, it is easy for it to separate from the needle groove 421 due to gravity. The setting of the needle guard 402 avoids this problem.

[0120] See Figure 6 In this embodiment, the needle insertion assembly 4 further includes a first vacuum suction member 403. At least a portion of the first vacuum suction member 403 is mounted on the support platform 41. The first vacuum suction member 403 serves as a component for facilitating the acupuncture needle 1 to enter the needle insertion groove 421 and preventing the acupuncture needle 1 from easily separating from the needle insertion groove 421.

[0121] And / or, the pipe assembly 5 further includes a second vacuum suction member 54, at least a portion of which is mounted on the support base 51. The second vacuum suction member 54 serves as a component for facilitating the plastic pipe 2 into the pipe groove 521 and preventing the plastic pipe 2 from easily separating from the pipe groove 521.

[0122] The first vacuum adsorption member 403 will be described in the following description, and the second vacuum adsorption member 54 will be described in the same way: In some embodiments, the inner space of the needle groove 421 is connected to the inner space of the needle wheel 42, and the first vacuum adsorption member 403 causes the acupuncture needle 1 to enter the needle groove 421 by adjusting the pressure of the inner space of the needle wheel 42.

[0123] It should be noted that the technology for achieving vacuum adsorption is existing technology and is well known to those skilled in the art. The first vacuum adsorption component 403 can use an existing vacuum adsorption device that can achieve the above purpose, and no specific restrictions are imposed here.

[0124] Similar to the needle protector 402, the first vacuum adsorption component 403 can also prevent the acupuncture needle 1 from separating from the needle slot 421 before entering the predetermined area.

[0125] See Figure 6 In this embodiment, the needle assembly 4 further includes a first detection sensor 404 disposed above the support platform 41; the first detection sensor 404 serves as a component for detecting the number of acupuncture needles 1 in the region between the coarse dividing wheel 44 and the needle-arranging wheel 42.

[0126] Some of the content is explained here, as follows:

[0127] The needle belt 46, the coarse dividing pulley 44 and the needle row wheel 42 do not always need to be operated synchronously;

[0128] In this application, all sensors are existing sensors, and the types of sensors, signal transmission methods, and detection methods are existing technologies and well known to those skilled in the art. This application does not impose any specific limitations.

[0129] In some embodiments, the coarse dividing wheel 44 only operates when the number of acupuncture needles 1 detected by the first detection sensor 404 is small (e.g., zero), to avoid the above-mentioned problems such as the misalignment of acupuncture needles 1 caused by the accumulation of acupuncture needles 1.

[0130] See Figure 5 In this embodiment, the pipe assembly 5 further includes an upper pipe belt 55 and an upper pipe belt drive 56;

[0131] The upper tube belt drive 56 is connected to the support base 51 and serves as a component for driving the upper tube belt 55 to move.

[0132] The upper tube belt 55 serves as a component for conveying the plastic tube 2 along a second predetermined path;

[0133] The direction of the second predetermined path is perpendicular to the extension direction of the pipe channel 521.

[0134] In some embodiments, the upper tube belt drive 56 is configured as a drive motor.

[0135] In some embodiments, the upper tube belt 55 and the upper tube belt drive 56 constitute a conventional belt conveyor.

[0136] The upper pipe belt 55 is used in conjunction with the pipe laying wheel 52. By placing a large number of plastic pipes 2 onto the upper pipe belt 55 at once, it avoids the need to repeatedly remove the plastic pipes 2 from the structure that loads them. It also makes it easier to pre-adjust the orientation of the plastic pipes 2 before they enter the pipe laying groove 521.

[0137] The direction of the second predetermined path is perpendicular to the extension direction of the pipe channel 521, which facilitates the entry of the plastic pipe 2 into the pipe channel 521.

[0138] See Figure 5 In this embodiment, the pipe assembly 5 further includes a second detection sensor 57 disposed above the support base 51; the second detection sensor 57 serves as a component for detecting the number of plastic pipes 2 in the area between the upper pipe belt 55 and the pipe wheel 52.

[0139] In some embodiments, the upper tube belt 55 only operates when the number of plastic tubes 2 detected by the second detection sensor 57 is small (e.g., zero), to avoid the aforementioned problems such as plastic tube 2 skewing caused by the accumulation of plastic tubes 2.

[0140] In some embodiments, this application also includes a third detection sensor and a fourth detection sensor. The third detection sensor is used to detect the pipe tray 521, and the fourth detection sensor is used to detect the needle tray 421. Taking the third detection sensor as an example, when the third detection sensor detects that there is no plastic tube 2 in the pipe tray 521, the pipe tray wheel 52 resets and rotates a certain distance.

[0141] See Figures 7-9 In some embodiments, the pipe assembly 5 further includes a hopper 58 connected to the support base 51, and the plastic pipe 2 can be placed in the hopper 58 in advance.

[0142] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
