[0019] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the implementation scope of the present invention is not limited thereto.

[0020] like Figures 1 to 8As shown, the tube conveying device for corona treatment of lip gloss tubes described in this embodiment comprises 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 arranged on the vertical arm of the mounting plate 1, a plurality of corona rollers 4 arranged at intervals on one side of the vertical arm of the mounting plate 1 and located above the conveying device 3, and a plurality of first driving members arranged at intervals 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; The transmission device 3 is uniformly provided with telescopic devices 6 along the circumferential direction; a second driving member is provided on the transmission 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 member is connected between the tensioning assembly 63 and the second driving member; a third driving member coaxial with the telescopic device 6 is provided on the transmission device 3 corresponding to each telescopic device 6; the outer surface of the third driving member is coated with a sticky layer (not shown in the figure); A fourth driving member is also provided on one side of the vertical arm of the mounting plate 1 ; the fourth driving member has a first driving portion 81 and a second driving portion 82 .

[0021] 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.

[0022] 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 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 being 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 one by one.

[0023] Specifically, Figures 1 to 4 As shown, the telescopic device 6 is in an extended state in a 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 a retracted state. Figure 2 and Figure 8 As shown, the fourth driving member is a track ring 8, the first driving portion 81 is arranged on one end of the lower parallel section of the track ring 8 close to the feeding device 2; the second driving portion 82 is arranged in the upper half area of ​​the arc section of the track ring 8 away from the feeding device 2.

[0024] In actual use, the feeding device 2 transports the lip gloss tube to be corona treated to the predetermined position in sequence, 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 in 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 in an extended state through the linkage member, the telescopic device 6 drives the tensioning component 63 to extend into the lip gloss tube, the tensioning component 63 tensions the lip gloss tube, thereby providing reliable support for the lip gloss tube, ensuring that the lip gloss tube is stable and avoids tilting, so as to ensure the accuracy and effect of the corona treatment, and 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 to move and pass under each corona roller 4 in sequence; When the third driving member cooperates with the first driving member, the first driving member causes the third driving member to drive the lip gloss tube to rotate, thereby realizing the turning over of the lip gloss tube. As the transmission chain module 33 rotates, the third driving member cooperates with each first driving member in turn, thereby ensuring that each surface of the lip gloss tube can receive uniform corona treatment. After the corona treatment of each corona roller 4 is performed on the lip gloss tube, the transmission chain module 33 drives the telescopic device 6 and the lip gloss tube to continue to move until the second driving member cooperates with the second driving portion 82 of the fourth driving member, the second driving member puts the telescopic device 6 in the storage state, and the telescopic device 6 drives the tensioning assembly 63 to withdraw the lip gloss tube. At this time, the lip gloss tube can be separated from the conveying device 3 to proceed to the next process. 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 be corona treated, thus completing a cycle.

[0025] In this embodiment, the second driving member is driven by the conveying device 3 to cooperate with the fourth driving member during the circular motion, thereby controlling the telescopic state of the telescopic device 6 to realize the taking and placing of the lip gloss tube. At the same time, the first driving member cooperates with the third driving member, and a sticky layer is provided on the third driving member, so that the lip gloss tube can be automatically turned over during the process of driving the lip gloss tube to move, thereby ensuring that all surfaces of the lip gloss tube are uniformly subjected to corona treatment, which is conducive to improving the adhesion and treatment consistency of the hot stamping material, and also reduces manual intervention, reduces human errors, and improves production efficiency and product quality.

[0026] 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.

[0027] like Figures 2 to 6As 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 a tooth structure 83 is provided on both the first driving part 81 and the second driving part 82. Specifically, when the gear structure 621 of the winding shaft 62 is meshed with the tooth structure 83 of the first driving part 81, the tooth structure 83 of the first driving part 81 drives the winding shaft 62 to rotate through the gear structure 621, and the traction rope 64 is reeled in during the rotation of the winding shaft 62, so that the telescopic device 6 is switched from the extended state to the retracted state; similarly, when the gear structure 621 of the winding shaft 62 is meshed with the tooth structure 83 of the second driving part 82, the tooth structure 83 of the second driving part 82 drives the winding shaft 62 to rotate through the gear structure 621, and the traction rope 64 is reeled in during the rotation of the winding shaft 62, so that the telescopic device 6 is switched from the extended state to the retracted state.

[0028] like Figures 1 to 7 As shown, in the tube 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; and the traction rope 64 is fixedly connected to the tensioning sleeve 631.

[0029] Specifically, when the gear structure 621 of the winding shaft 62 is meshed 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, so that the multi-stage telescopic sleeve 61 is retracted and is in the storage state; and when the gear structure 621 of the winding shaft 62 is meshed 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 to move, so that the multi-stage telescopic sleeve 61 is retracted and is 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, so that the multi-stage telescopic sleeve 61 is extended and in 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, avoiding tilting, thereby facilitating uniform corona treatment of each surface of the lip gloss tube.

[0030] like Figures 3 to 7As 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 with 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 respectively hinged with the first slider 6321 and the second slider 6322; when the multi-stage telescopic sleeve 61 is in the extended state, the third spring 6326 enables the friction block 6323 to pass through the tensioning sleeve 631 outward.

[0031] Specifically, when the multi-stage telescopic sleeve 61 is transformed into the storage state, since the tensioning sleeve 631 slides inwardly relative to the multi-stage telescopic sleeve 61, the multi-stage telescopic sleeve 61 cooperates with the inclined wedge 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 outwardly, and 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, and 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; When the multi-stage telescopic sleeve 61 is changed to the extended state, since the tensioning sleeve 631 slides outward relative to the multi-stage telescopic sleeve 61, the multi-stage telescopic sleeve 61 and the inclined surface of the first slider 6321 are disengaged from the wedge-shaped cooperation, that is, the multi-stage telescopic sleeve 61 releases the squeezing of 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 to extend outward from 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, thereby 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 corona treatment.

[0032] In this embodiment, the multi-stage telescopic sleeve 61 is composed of a plurality of telescopic sections that are slidably sleeved in sequence. The friction force between adjacent telescopic sections can be set to gradually decrease or increase from one end close to the tensioning assembly 63 to the other end, so that each telescopic section can be contracted or extended in sequence; for example, in this embodiment, the friction force between adjacent telescopic sections is set to gradually decrease from one end close to the tensioning assembly 63 to the other end.

[0033] like Figure 1 , Figures 3 to 6 and Figure 8 As shown, in the pipe conveying equipment described in this embodiment, in some implementations, the feeding device 2 is provided with a waiting position 21 for transmission; the mounting plate 1 is provided with a first limiting structure at a position between the waiting position 21 for transmission and the first driving part 81; the second limiting structure is provided on the second driving member; the first limiting structure and the second limiting structure cooperate to limit the second driving member, so that the telescopic device 6 remains in the retracted state.

[0034] Specifically, the feeding device 2 sequentially conveys the lip gloss tubes to be coronaed to the waiting position 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 meshed 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, so that the multi-stage telescopic sleeve 61 is contracted and 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 tightened. The traction rope 64 is driven to unwind, and the winding shaft 62 rotates in the opposite direction, so that the multi-stage telescopic sleeve 61 is extended and in an extended state, and the multi-stage telescopic sleeve 61 drives the tensioning assembly 63 to extend into the lip gloss tube in the waiting position 21, and the multi-stage telescopic sleeve 61 and the inclined surface of the first slider 6321 are separated from the wedge-shaped cooperation, and the multi-stage telescopic sleeve 61 releases the squeezing of 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 to extend outward from 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. Then the transmission chain module 33 drives each telescopic device 6, the winding shaft 62, the third driving member, and the lip gloss tube to make a circular motion, thereby removing the lip gloss tube in the waiting position 21; then the feeding device 2 conveys the next lip gloss tube to be coronaed to the waiting position 21, waiting for the next telescopic device 6 to move it out of the waiting position 21.

[0035] like Figures 3 to 6 , Figure 8 As shown, in the pipe conveying device described in this embodiment, in some embodiments, the first limiting structure is at least two limiting grooves 11 arranged at intervals; the second limiting structure is at least two limiting pins 622 arranged at intervals. The number of limiting grooves 11 and limiting pins 622 can be set according to actual design needs. In this embodiment, the number of limiting grooves 11 and limiting pins 622 is set to four each. When the gear structure 621 of the winding shaft 62 is disengaged from the tooth structure 83 of the first driving part 81, each limiting pin 622 is correspondingly inserted into the limiting groove 11, thereby limiting the rotational freedom of the winding shaft 62 to prevent the multi-stage telescopic sleeve 61 from extending under the action of the first spring 65.

[0036] In the tube conveying device described in this embodiment, in some implementations, the adhesive force of the adhesive layer is smaller than the gravity on the lip gloss tube. With such a configuration, when the gear structure 621 of the winding shaft 62 meshes with the tooth structure 83 of the second driving part 82, the tooth structure 83 of the second driving part 82 drives the winding shaft 62 to rotate through the gear structure 621, and the winding shaft 62 reels the traction rope 64, thereby causing the multi-stage telescopic sleeve 61 to contract. When the multi-stage telescopic sleeve 61 drives the tensioning assembly 63 to be completely in the storage state, the tensioning assembly 63 moves out of the lip gloss tube. At this time, the lip gloss tube after corona treatment can overcome the adhesive force of the adhesive layer under the action of its own gravity and fall from the third driving member, thereby realizing automatic unloading of the lip gloss tube without manual intervention. 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.

[0037] like Figure 1 and Figure 2 As shown, the tube conveying device described in this embodiment, specifically, the first driving member is a rack 5, the rack 5 is fixedly mounted on the mounting plate 1; the third driving member is a gear ring 7, the gear ring 7 is rotatably arranged on the transmission chain module 33. When the gear ring 7 moves to engage with the rack 5, the rack 5 drives the gear ring 7 to rotate, so that the gear ring 7 can drive the lip gloss tube to rotate through the adhesive force of the adhesive layer, and realize the automatic turning over of the lip gloss tube without manual intervention.

[0038] 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.
