[0002] In modern cosmetics packaging, lip gloss tubes are a common packaging container, and the quality of their surface treatment directly impacts the product's aesthetics and functionality. Corona treatment, a commonly used surface treatment process, effectively improves the hydrophilicity and adhesion of lip gloss tubes, providing an excellent foundation for subsequent hot stamping.

[0003] However, the existing corona treatment technology has many shortcomings in practical applications: First, the existing corona treatment usually requires the lip gloss tube to be fixed on a specific device and then placed in a corona generating device for treatment manually or semi-automatically.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.

[0031] like Figures 1 to 8 As shown, the tube conveying device for corona treatment of lip gloss tubes described in this embodiment includes an L-shaped mounting plate 1, a feeding device 2 fixedly mounted on the horizontal arm of the mounting plate 1 and located at one end of the mounting plate 1, a conveying device 3 provided on the vertical arm of the mounting plate 1, a plurality of corona rollers 4 spaced apart on one side of the vertical arm of the mounting plate 1 and above the conveying device 3, and a plurality of first driving members spaced apart on one side of the vertical arm of the mounting plate 1 and respectively located between two adjacent corona rollers 4; the feeding device 2 is used to convey the lip gloss tubes to be corona treated;

[0032] The conveying device 3 is provided with telescopic devices 6 uniformly distributed along the circumference; a second driving member is provided on the conveying device 3 corresponding to each telescopic device 6; a tensioning assembly 63 is provided at the movable end of the telescopic device 6; a linkage is connected between the tensioning assembly 63 and the second driving member; a third driving member is provided on the conveying device 3 corresponding to each telescopic device 6, which is coaxial with the telescopic device 6; the outer surface of the third driving member is coated with an adhesive layer (not shown in the figure);

[0033] A fourth driving member is further provided on one side of the vertical arm of the mounting plate 1 ; the fourth driving member includes a first driving portion 81 and a second driving portion 82 .

[0034] like Figure 1 and Figure 2 As shown, the number of corona rollers 4 and first driving members can be set according to actual design requirements. For example, in this embodiment, the number of corona rollers 4 is four, and correspondingly, the number of first driving members is three.

[0035] like Figure 1 and Figure 2 As shown, the conveying device 3 is provided with a motor 31, a transmission wheel 32 and a transmission chain module 33; the motor 31 is fixedly mounted on the mounting plate 1, and the two transmission wheels 32 are installed on the mounting plate 1 at intervals, and the output end of the motor 31 is connected to one of the transmission wheels 32; the transmission chain module 33 is wound around the two transmission wheels 32; the transmission chain module 33 (represented by a solid body in the figure) is formed by a plurality of chain link units hinged end to end in sequence; the telescopic device 6, the second driving member, and the third driving member are installed on the chain link units in a one-to-one correspondence.

[0036] Specifically, if Figures 1 to 4 As shown, the telescopic device 6 is in the extended state in the natural state; when the second driving member cooperates with the first driving part 81 and the second driving part 82 respectively, the second driving member puts the telescopic device 6 in the retracted state. Figure 2 and Figure 8As shown, the fourth driving member is a runway ring 8, and the first driving part 81 is arranged on one end of the lower parallel section of the runway ring 8 close to the feeding device 2; the second driving part 82 is arranged in the upper half area of ​​the arc section of the runway ring 8 away from the feeding device 2.

[0037] During actual use, the feeding device 2 sequentially conveys the lip gloss tubes to be corona treated to the predetermined positions, the motor 31 drives the transmission wheel 32 to rotate, the transmission wheel 32 drives the transmission chain module 33 to rotate, and the transmission chain module 33 drives each telescopic device 6, the second driving member, and the third driving member to perform circular motion; when the second driving member contacts the first driving portion 81 of the fourth driving member, the second driving member puts the telescopic device 6 into a retracted state until the telescopic device 6 rotates to align with the lip gloss tube at the predetermined position, the second driving member puts the telescopic device 6 into an extended state through the linkage member, and the telescopic device 6 drives the tensioning assembly 63 to extend into the lip gloss tube. The tensioning assembly 63 tensions the lip gloss tube, thereby providing reliable support for the lip gloss tube, ensuring that the lip gloss tube is stable and prevents tilting, thereby ensuring the accuracy and effect of the corona treatment. At the same time, the adhesive layer of the third driving member bonds the lip gloss tube, and then the telescopic device 6 drives the lip gloss tube to continue moving and pass under each corona roller 4 in sequence;

[0038] When the third driving member cooperates with the first driving member, the first driving member causes the third driving member to rotate the lip gloss tube, thereby turning the lip gloss tube over. As the transmission chain module 33 rotates, the third driving member cooperates with each first driving member in turn, thereby ensuring that all surfaces of the lip gloss tube receive uniform corona treatment.

[0039] After the corona rollers 4 have applied corona treatment to the lip gloss tubes, the transmission chain module 33 drives the telescopic device 6 and the lip gloss tubes to continue moving until the second drive member engages with the second drive portion 82 of the fourth drive member. The second drive member puts the telescopic device 6 into the retracted state, and the telescopic device 6 drives the tensioning assembly 63 to withdraw the lip gloss tubes. At this point, the lip gloss tubes can be detached from the conveyor device 3 for the next process.

[0040] After the second driving member is disengaged from the second driving portion 82 of the fourth driving member, the second driving member causes the telescopic device 6 to be in the extended state again. In the extended state of the second driving member, the telescopic device 6 drives the next lip gloss tube to undergo corona treatment, thus completing a cycle.

[0041] In this embodiment, the conveyor 3 drives the second drive member in a circular motion, which cooperates with the fourth drive member to control the extension and retraction of the retractable device 6, thereby enabling the lip gloss tube to be taken in and out. Furthermore, the first and third drive members cooperate, and an adhesive layer is provided on the third drive member, so that the lip gloss tube can be automatically turned over during the movement of the lip gloss tube, thereby ensuring that all surfaces of the lip gloss tube receive the corona treatment uniformly. This improves the adhesion of the hot stamping material and the consistency of the treatment, reduces manual intervention, reduces human error, and improves production efficiency and product quality.

[0042] In addition, the tube conveying equipment of this embodiment has strong compatibility and adaptability, and can meet the production requirements of lip gloss tubes of different specifications.

[0043] like Figures 2 to 6 As shown, in some embodiments of the pipe conveying device described in this embodiment, the second driving member is a winding shaft 62, and a gear structure 621 is provided on the winding shaft 62; the linkage member is a traction rope 64; and the first driving portion 81 and the second driving portion 82 are both provided with a tooth structure 83. Specifically, when the gear structure 621 of the winding shaft 62 is engaged with the tooth structure 83 of the first driving portion 81, the tooth structure 83 of the first driving portion 81 drives the winding shaft 62 to rotate via the gear structure 621, and the traction rope 64 is reeled in during the rotation of the winding shaft 62, thereby switching the telescopic device 6 from the extended state to the retracted state; similarly, when the gear structure 621 of the winding shaft 62 is engaged with the tooth structure 83 of the second driving portion 82, the tooth structure 83 of the second driving portion 82 drives the winding shaft 62 to rotate via the gear structure 621, and the traction rope 64 is reeled in during the rotation of the winding shaft 62, thereby switching the telescopic device 6 from the extended state to the retracted state.

[0044] like Figures 1 to 7 As shown, in the pipe conveying equipment described in this embodiment, in some embodiments, the telescopic device 6 includes a multi-stage telescopic sleeve 61 and a first spring 65 arranged in the multi-stage telescopic sleeve 61; the tensioning assembly 63 includes a tensioning sleeve 631 and a plurality of tensioning units uniformly distributed on the tensioning sleeve 631 along the circumferential direction; the tensioning sleeve 631 is slidably sleeved on the multi-stage telescopic sleeve 61; the two ends of the first spring 65 are respectively connected to the tensioning sleeve 631 and the conveying device 3; the traction rope 64 is fixedly connected to the tensioning sleeve 631.

[0045] Specifically, when the gear structure 621 of the winding shaft 62 is engaged with the tooth structure 83 of the first driving part 81 or the second driving part 82, the first driving part 81 or the second driving part 82 cooperates with the gear structure 621 through the tooth structure 83 to drive the winding shaft 62 to rotate, and the winding shaft 62 reels the traction rope 64. The traction rope 64 pulls the tensioning sleeve 631 to overcome the elastic force of the first spring 65, thereby causing the multi-stage telescopic sleeve 61 to retract and be in the storage state; and when the gear structure 621 of the winding shaft 62 is engaged with the first driving part 81 or the second driving part 82, the first driving part 81 or the second driving part 82 cooperates with the gear structure 621 through the tooth structure 83 to drive the winding shaft 62 to rotate, and the winding shaft 62 reels the traction rope 64. The traction rope 64 pulls the tensioning sleeve 631 to overcome the elastic force of the first spring 65, thereby causing the multi-stage telescopic sleeve 61 to retract and be in the storage state. After the tooth structure 83 of the part 81 or the second driving part 82 is disengaged, the first spring 65 is reset and deformed, pushing the tensioning sleeve 631 to move outward, and the tensioning sleeve 631 drives the traction rope 64 to unwind, and the winding shaft 62 rotates in the opposite direction, thereby extending the multi-stage telescopic sleeve 61 to an extended state, and at the same time, each group of tensioning units is in a tensioned state, providing reliable support for the lip gloss tube, increasing the friction between the telescopic device 6 and the inner wall of the lip gloss tube, ensuring the stability of the lip gloss tube, and avoiding tilting, thereby facilitating uniform corona treatment of all surfaces of the lip gloss tube.

[0046] like Figures 3 to 7 As shown, in the pipe conveying device described in this embodiment, in some embodiments, each group of tensioning units includes a first slider 6321, a second slider 6322, a friction block 6323 and a connecting rod 6324; the first slider 6321 is slidably arranged on the tensioning sleeve 631 close to one end of the multi-stage telescopic sleeve 61; the first slider 6321 is provided with an inclined surface for wedge-shaped cooperation with the multi-stage telescopic sleeve 61; the second slider 6322 and the friction block 6323 are respectively slidably arranged on the tensioning sleeve 631 away from the multi-stage telescopic sleeve One end of the sleeve 61; the middle part of the connecting rod 6324 is hinged to the tensioning sleeve 631; a second spring 6325 is connected between the first slider 6321 and the tensioning sleeve 631; a third spring 6326 is connected between the second slider 6322 and the friction block 6323; the two ends of the connecting rod 6324 are hinged to the first slider 6321 and the second slider 6322 respectively; when the multi-stage telescopic sleeve 61 is in the extended state, the third spring 6326 causes the friction block 6323 to pass outward through the tensioning sleeve 631.

[0047] Specifically, when the multi-stage telescopic sleeve 61 is transformed into the storage state, the tensioning sleeve 631 slides inwardly relative to the multi-stage telescopic sleeve 61, and the multi-stage telescopic sleeve 61 cooperates with the inclined wedge shape of the first slider 6321 and squeezes the first slider 6321, so that the first slider 6321 overcomes the elastic force of the second spring 6325 and slides outward. The second spring 6325 is compressed. At the same time, during the outward sliding process of the first slider 6321, the connecting rod 6324 is synchronously driven to swing, so that the second slider 6322 slides inwardly. The second slider 6322 drives the friction block 6323 to slide inwardly through the third spring 6326, so that the friction block 6323 is retracted inwardly into the tensioning sleeve 631.

[0048] When the multi-stage telescopic sleeve 61 changes to the extended state, the tensioning sleeve 631 slides outward relative to the multi-stage telescopic sleeve 61, and the inclined surface of the multi-stage telescopic sleeve 61 and the first slider 6321 are disengaged from the wedge-shaped fit, that is, the multi-stage telescopic sleeve 61 releases the pressure on the first slider 6321. At this time, the second spring 6325 pushes the first slider 6321 to slide inward, and the first slider 6321 drives the second slider 6322 to slide outward through the connecting rod 6324. The second slider 6322 pushes the friction block 6323 outward through the tensioning sleeve 631 through the third spring 6326, so that the friction block 6323 is supported on the inner wall of the lip gloss tube, increasing the friction between the multi-stage telescopic sleeve 61 and the inner wall of the lip gloss tube, ensuring the stability of the lip gloss tube, avoiding tilting, and ensuring the accuracy and effect of the corona treatment.

[0049] In this embodiment, the multi-stage telescopic sleeve 61 is composed of multiple telescopic sections that are slidably connected in sequence. The friction between adjacent telescopic sections can be configured to gradually decrease or increase from one end near the tensioning assembly 63 to the other end, allowing each telescopic section to contract or extend sequentially. For example, in this embodiment, the friction between adjacent telescopic sections is configured to gradually decrease from one end near the tensioning assembly 63 to the other end.

[0050] like Figure 1 、 Figures 3 to 6 and Figure 8 As shown, in the pipe conveying equipment described in this embodiment, in some embodiments, the feeding device 2 is provided with a position to be conveyed 21; the mounting plate 1 is provided with a first limiting structure at a position between the position to be conveyed 21 and the first driving portion 81; the second driving member is provided with a second limiting structure; the first limiting structure and the second limiting structure cooperate to limit the second driving member, so that the telescopic device 6 remains in a retracted state.

[0051] Specifically, the feeding device 2 sequentially conveys the lip gloss tubes to be corona-treated to the position to be transferred 21, the motor 31 drives the transmission wheel 32 to rotate, the transmission wheel 32 drives the transmission chain module 33 to rotate, and the transmission chain module 33 drives each telescopic device 6, the winding shaft 62, and the third driving member to perform circular motion; when the gear structure 621 of the winding shaft 62 is engaged with the tooth structure 83 of the first driving part 81, the first driving part 81 cooperates with the gear structure 621 through the tooth structure 83 to drive the winding shaft 62 to rotate, and the winding shaft 62 reels the traction rope 64, and the traction rope 64 pulls the tensioning sleeve 631 to overcome the elastic force of the first spring 65 to move, thereby causing the multi-stage telescopic sleeve 61 to contract and be in the storage state, that is, when the tensioning assembly 63 is fully stored, as shown in FIG. Figure 1 and Figure 8As shown, at this time, the gear structure 621 of the winding shaft 62 is disengaged from the tooth structure 83 of the first driving part 81, and at the same time, the first limiting structure cooperates with the first limiting structure to limit the winding shaft 62, limiting the rotational freedom of the winding shaft 62, so that the winding shaft 62 keeps winding the traction rope 64, that is, the multi-stage telescopic sleeve 61 and the tensioning assembly 63 remain in the storage state, until the transmission chain module 33 drives the winding shaft 62, the multi-stage telescopic sleeve 61 and the tensioning assembly 63 to move to align with the to-be-transmitted position 21, the first limiting structure is disengaged from the first limiting structure, that is, the restriction on the winding shaft 62 is released, and at this time the first spring 65 is reset and deformed, pushing the tensioning sleeve 631 to move outward, and the tensioning sleeve 631 is The traction rope 64 is driven to unwind, and the winding shaft 62 rotates in the opposite direction, thereby extending the multi-stage telescopic sleeve 61 to an extended state. The multi-stage telescopic sleeve 61 drives the tensioning assembly 63 to extend into the lip gloss tube in the waiting position 21. The multi-stage telescopic sleeve 61 and the inclined surface of the first slider 6321 are disengaged from the wedge-shaped fit. The multi-stage telescopic sleeve 61 releases the pressure on the first slider 6321. At this time, the second spring 6325 pushes the first slider 6321 to slide inward. The first slider 6321 drives the second slider 6322 to slide outward through the connecting rod 6324. The second slider 6322 pushes the friction block 6323 outward through the tensioning sleeve 631 through the third spring 6326, so that the friction block 6323 supports the inner wall of the lip gloss tube.

[0052] The transmission chain module 33 then drives the telescopic devices 6, the winding shaft 62, the third drive member, and the lip gloss tube to perform a circular motion, thereby removing the lip gloss tube in the waiting position 21. The feeding device 2 then conveys the next lip gloss tube to be corona-treated to the waiting position 21, where it waits for the next telescopic device 6 to remove it from the waiting position 21.

[0053] like Figures 3 to 6 、 Figure 8 As shown, in some embodiments of the pipe conveying device described in this embodiment, the first limiting structure comprises at least two spaced-apart limiting slots 11, and the second limiting structure comprises at least two spaced-apart limiting pins 622. The number of limiting slots 11 and limiting pins 622 can be set according to actual design requirements. In this embodiment, four limiting slots 11 and four limiting pins 622 are provided. When the gear structure 621 of the winding shaft 62 disengages from the tooth structure 83 of the first drive portion 81, each limiting pin 622 engages in a corresponding manner within the limiting slots 11, thereby limiting the rotational freedom of the winding shaft 62 and preventing the multi-stage telescopic sleeve 61 from extending under the action of the first spring 65.

[0054] In some embodiments of the tube conveying device described in this embodiment, the adhesive force of the adhesive layer is less than the gravity acting on the lip gloss tube. This arrangement allows the gear structure 621 of the winding shaft 62 to mesh with the tooth structure 83 of the second drive portion 82, and the tooth structure 83 of the second drive portion 82, via the gear structure 621, to drive the winding shaft 62 to rotate, causing the winding shaft 62 to reel in the traction rope 64, thereby contracting the multi-stage telescopic sleeve 61. When the multi-stage telescopic sleeve 61 drives the tensioning assembly 63 to be fully retracted, the tensioning assembly 63 is removed from the lip gloss tube. At this point, the corona-treated lip gloss tube, under the action of its own gravity, overcomes the adhesive force of the adhesive layer and falls from the third drive member, thereby achieving automatic unloading of the lip gloss tube without manual intervention.

[0055] When the third driving member rotates to cooperate with the first driving member, the first driving member drives the third driving member to rotate, and the third driving member drives the lip gloss tube to rotate through the adhesive force of the adhesive layer, thereby turning the lip gloss tube over to ensure that all surfaces of the lip gloss tube can be corona treated.

[0056] like Figure 1 and Figure 2 As shown, the tube conveying device of this embodiment comprises a first drive member, a rack 5, fixedly mounted on a mounting plate 1; and a third drive member, a gear ring 7, rotatably mounted on a transmission chain module 33. When the gear ring 7 engages with the rack 5, the rack 5 drives the gear ring 7 to rotate. This, in turn, allows the gear ring 7 to rotate the lip gloss tube through the adhesive force of the adhesive layer, automatically turning the lip gloss tube over without manual intervention.

[0057] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the protection scope of the patent application of the present invention.
