Description

Technical Field

[0001] The invention belongs to the technical field of eye shadow pen production and processing, and in particular relates to a liquid eye shadow pen packaging elevator. Background Art

[0002] During the processing of liquid eyeshadow, it is necessary to transport it to the assembly line via an elevator after production, and then the workers on the assembly line will carry out the subsequent packaging of the eyeshadow. However, the elevators in the existing technology often have the following technical problems when transporting eyeshadow:

[0003] 1. The direction of the eyeshadow pencil cannot be adjusted, resulting in different directions of the eyeshadow pencils on the assembly line. The staff needs to manually observe and flip the eyeshadow pencils during packaging, which is a cumbersome operation.

[0004] 2. During the lifting process, the eye shadow pencils cannot be transported in sequence, which causes the eye shadow pencils to easily accumulate during transportation and further slide off the elevator, affecting the lifting efficiency. Summary of the Invention

[0005] The purpose of the present invention is to address the problems raised in the above-mentioned background technology and provide a liquid eyeshadow pencil packaging elevator that can transport eyeshadow pencils with different directions from both sides to the turning bucket according to their own weight, so that the direction in which the eyeshadow pencils fall on the lifting belt is always consistent, making it easier for staff to carry out subsequent packaging work.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A liquid eyeshadow packaging elevator, comprising:

[0008] A lifting frame, wherein two lifting rollers are fixedly installed above the lifting frame through a support plate, a lifting belt is sleeved between the two lifting rollers, and a plurality of transport frames are provided on the lifting belt;

[0009] A steering mechanism is fixedly mounted above the lifting frame and is used to steer the eyeshadow pencil before lifting and transportation, so that the directions of the pen tip and the pen tail of the eyeshadow pencil remain unchanged during lifting. The steering mechanism includes a steering bucket fixedly mounted above the lifting frame, a support block is fixedly mounted inside the steering bucket, a steering plate is hingedly mounted on the support block through a first hinge seat, two baffles are fixedly mounted above the steering plate, and abutment plates are slidably mounted on the steering plate at positions on both sides of the two baffles, and each of the abutment plates extends to a position below the steering plate. A lifting plate is fixedly installed on each of the steering plates, and the lifting plate is elastically connected to the lower wall of the steering plate through two first springs. A triangular guide plate is fixedly installed on the lifting plate through an extension rod. A control cavity is opened inside the steering plate, and a counterweight block is slidably installed inside the control cavity. Both sides of the counterweight block are elastically connected to the inner wall of the control cavity through a second spring. Two connecting rods are fixedly installed on the counterweight block. The portion of each connecting rod extending outside the steering plate is hinged to a guide wheel through a second hinge seat, and the two guide wheels respectively contact and roll with the two triangular guide plates;

[0010] The unloading mechanism is fixedly installed between the lifting frame and the steering mechanism, and is used to transport the eye shadow pencil to the lifting frame in sequence. The unloading mechanism includes two fixed plates fixedly installed between the lifting frame and the steering bucket. The two fixed plates are elastically connected with unloading plates through a number of third springs. A unloading port is opened in the middle of the unloading plate. Elastic retractable arc plates are fixedly installed on both sides of the lower wall of the unloading plate. A rotating rod is rotatably installed above the unloading plate through two mounting seats. A first gear is provided on the rotating rod, and racks are fixedly installed on the two fixed plates. The two racks are respectively meshed with the two first gears. Each rotating rod is provided with a second gear. An arc-shaped tooth groove is fixedly installed on each elastic retractable arc plate, and the two second gears are respectively meshed with the two arc-shaped tooth grooves.

[0011] Preferably, a motor is provided on the support plate, the output shaft of the motor is fixedly connected to one of the lifting rollers, and a first synchronous wheel is provided at one end of the two lifting rollers away from the motor, and a first synchronous belt is sleeved between the two first synchronous wheels.

[0012] Preferably, an extension plate is fixedly mounted on the support plate, a fan is rotatably mounted on the lower wall of the extension plate, the fan is located directly above the steering bucket, and the fan is connected to the lifting roller via a transmission mechanism.

[0013] Preferably, the transmission mechanism includes a transmission rod rotatably mounted on an extension plate, the transmission rod is provided with a bevel gear ring, the lifting roller is provided with a bevel gear at one end close to the transmission rod, the bevel gear ring and the bevel gear are engaged with each other, a second synchronous wheel is provided on the transmission rod and the fan output shaft, and a second synchronous belt is sleeved between the two second synchronous wheels.

[0014] Preferably, the guide wheel pushes the triangular guide plate to move downward when contacting the triangular guide plate.

[0015] Preferably, two material guide rails are fixedly installed on the inner wall of the steering bucket.

[0016] Compared with the existing technology, the advantages of this liquid eyeshadow packaging elevator are:

[0017] 1. The present invention provides a steering mechanism so that the eyeshadow pencil first falls on the steering plate of the steering bucket before lifting. Due to the different weights on both sides of the eyeshadow pencil, the eyeshadow pencil drives the steering plate to deflect toward the side with greater weight, thereby allowing the counterweight block to slide in the control cavity. The connecting rod and the guide wheel further push the triangular guide plate to move downward relative to the steering plate, causing the abutment plate on this side to move downward and no longer block the eyeshadow pencil. The eyeshadow pencil is guided into the inclined material guide barrel through the side guide track and further falls into the transport frame on the lifting belt through the inclined material guide barrel. The direction in which the eyeshadow pencil falls on the lifting belt is always consistent, thereby facilitating the staff to carry out subsequent packaging work.

[0018] 2. The present invention sets a discharge mechanism. When the eyeshadow pencil falls from the inclined guide cylinder to the lifting belt, the eyeshadow pencil first falls on the discharge port of the discharge plate. When the number of eyeshadow pencils at the discharge port increases to two, the weight of the eyeshadow pencils is sufficient to push the discharge plate down a sufficient distance. At this time, the rack drives the rotating rod to rotate a sufficient angle through the first gear, driving the elastic telescopic arc plate to retract, so that the eyeshadow pencil can fall onto the lifting belt through the discharge port, so that the eyeshadow pencil falls into each transport frame in turn during the transportation process, avoiding the eyeshadow pencil from accumulating on the lifting belt and causing the eyeshadow pencil to slip, thereby improving the lifting efficiency of the eyeshadow pencil.

[0019] 3. The present invention sets a first synchronous wheel and a first synchronous belt. When working, it only needs to drive one of the two lifting rollers to rotate through the motor, and the other lifting roller can be driven to rotate under the action of the first synchronous wheel and the first synchronous belt, so that the lifting belt runs to lift and transport the eye shadow pencil, saving the driving source and reducing the lifting cost.

[0020] 4. The present invention provides a fan and a transmission mechanism. When the eyeshadow pencil is transported to the steering bucket, the rotation of the fan can blow air above the steering bucket, thereby blowing away the dust on the surface of the eyeshadow pencil, thereby cleaning the eyeshadow pencil. At the same time, since the fan is driven by the transmission rod through the second synchronous wheel and the second synchronous belt, and the transmission rod is driven by the lifting roller through the bevel gear ring and the bevel gear, the cleaning effect of the eyeshadow pencil can be achieved without providing an additional driving source.

[0028] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0029] like Figures 1 to 6 As shown, a liquid eyeshadow packaging elevator includes an elevator frame 1, two elevator rollers 11 are fixedly installed above the elevator frame 1 through a support plate, a elevator belt 12 is sleeved between the two elevator rollers 11, and a plurality of transport frames 13 are provided on the elevator belt 12;

[0030] Steering mechanism 2, which is fixedly installed above the lifting frame 1 and is used to turn the eyeshadow pen before lifting and transportation, so that the direction of the pen head and the pen tail of the eyeshadow pen remains unchanged during lifting;

[0031] The unloading mechanism 3 is fixedly installed between the lifting frame 1 and the steering mechanism 2, and is used to transport the eye shadow pencils to the lifting frame 1 in sequence.

[0032] The steering mechanism 2 includes a steering bucket 21 fixedly mounted above the lifting frame 1, a support block 22 fixedly mounted inside the steering bucket 21, a steering plate 24 hingedly connected to the support block 22 through a first hinge seat 23, two baffles 25 fixedly mounted above the steering plate 24, and a support plate 26 slidingly mounted through the positions on both sides of the two baffles 25 on the steering plate 24, and each support plate 26 extending to the position below the steering plate 24 is fixedly mounted with a lifting plate 27, and the lifting plate 27 is elastically connected to the lower wall of the steering plate 24 by two first springs 28. 7 is fixedly mounted with a triangular guide plate 210 via an extension rod 29. A control chamber 211 is defined within the steering plate 24. A counterweight 212 is slidably mounted within the control chamber 211. Both sides of the counterweight 212 are elastically connected to the inner wall of the control chamber 211 via a second spring 213. Two connecting rods 214 are fixedly mounted on the counterweight 212. The portion of each connecting rod 214 extending outside the steering plate 24 is hingedly connected to a guide wheel 216 via a second hinge seat 215. The two guide wheels 216 respectively contact and roll with the two triangular guide plates 210.

[0033] When the guide wheel 216 contacts the triangular guide plate 210 , it pushes the triangular guide plate 210 to move downward.

[0034] Two material guide rails 7 are fixedly installed on the inner wall of the steering bucket 21.

[0035] Among them, an inclined material guide cylinder 8 is fixedly installed at the bottom of the steering bucket 21. The eye shadow pencil that slides down from the steering plate 24 can be transported into the inclined material guide cylinder 8 through the material guide track 7, and further transported to the lifting belt 12.

[0036] In order to solve the problem that the direction of the eye shadow pencil cannot be adjusted in the prior art, resulting in different directions of the eye shadow pencils on the assembly line, and the staff need to manually observe and flip the eye shadow pencils during packaging, which is a cumbersome operation, the present invention provides a steering mechanism 2. Before lifting, the eye shadow pencil is first dropped on the steering plate 24 of the steering bucket 21. Since the weights on both sides of the eye shadow pencil are different, the eye shadow pencil drives the steering plate 24 to deflect toward the side with greater weight. During the deflection process, since the control chamber 211 also deflects toward this side, the weight of the counterweight block 212 itself generates a component force in the opposite direction to the elastic force of the first spring 28 on this side. , so that the counterweight block 212 can slide in the control cavity 211, and further drive the guide wheel 216 to move close to the triangular guide plate 210 through the connecting rod 214 and the second hinge seat 215, and push the triangular guide plate 210 to move downward relative to the steering plate 24, so that the abutment plate 26 on this side moves downward and no longer blocks the eyeshadow pencil. The eyeshadow pencil is guided to the inclined guide cylinder 8 through the side guide track 7, and further falls into the transport frame 13 on the lifting belt 12 through the inclined guide cylinder 8, so that the direction in which the eyeshadow pencil falls on the lifting belt 12 is always consistent, thereby facilitating the staff to carry out subsequent packaging work.

[0037] The unloading mechanism 3 includes two fixed plates 31 fixedly installed between the lifting frame 1 and the steering bucket 21. The two fixed plates 31 are elastically connected with unloading plates 33 through a number of third springs 32. A unloading port 34 is opened in the middle of the unloading plate 33. Elastic telescopic arc plates 35 are fixedly installed on both sides of the lower wall of the unloading plate 33. A rotating rod 37 is rotatably installed above the unloading plate 33 through two mounting seats 36. A first gear 38 is provided on the rotating rod 37. Racks 39 are fixedly installed on the two fixed plates 31. The two racks 39 are respectively meshed with the two first gears 38. Each rotating rod 37 is provided with a second gear 310. An arc-shaped tooth groove 311 is fixedly installed on each elastic telescopic arc plate 35. The two second gears 310 are respectively meshed with the two arc-shaped tooth grooves 311.

[0038] In order to solve the problem that the eyeshadow pencils cannot be transported sequentially in the prior art, which causes the eyeshadow pencils to easily accumulate during transportation and further slide off the elevator, affecting the lifting efficiency, the present invention provides a discharge mechanism 3. When the eyeshadow pencils fall from the inclined guide cylinder 8 to the lifting belt 12, the eyeshadow pencils first fall on the discharge port 34 of the discharge plate 33. When there is only one eyeshadow pencil at the discharge port 34, the weight of the eyeshadow pencil is not enough to push the discharge plate 33 downward a sufficient distance. At this time, the elastic telescopic arc plate 35 clamps the eyeshadow pencil, and the eyeshadow pencil cannot fall on the lifting belt 12 When the number of eye shadow pencils at the discharge port 34 increases to two, the weight of the eye shadow pencils is sufficient to push the discharge plate 33 down a sufficient distance. At this time, the rack 39 drives the rotating rod 37 to rotate a sufficient angle through the first gear 38, and the rotating rod 37 drives the elastic telescopic arc plate 35 to retract through the second gear 310 and the arc-shaped tooth groove 311, so that the eye shadow pencils can fall onto the lifting belt 12 through the discharge port 34, so that the eye shadow pencils fall into each transport frame 13 in turn during the transportation process, avoiding the eye shadow pencils from accumulating on the lifting belt 12 and causing the eye shadow pencils to slip, thereby improving the lifting efficiency of the eye shadow pencils.

[0039] A motor 4 is provided on the support plate, and the output shaft of the motor 4 is fixedly connected to one of the lifting rollers 11 . A first synchronous wheel 41 is provided at one end of the two lifting rollers 11 away from the motor 4 , and a first synchronous belt 42 is sleeved between the two first synchronous wheels 41 .

[0040] It is worth mentioning that the present invention provides a first synchronous wheel 41 and a first synchronous belt 42. When working, it only needs to drive one of the two lifting rollers 11 to rotate through the motor 4, and the other lifting roller 11 can be driven to rotate under the action of the first synchronous wheel 41 and the first synchronous belt 42, so that the lifting belt 12 can run to lift and transport the eye shadow pencil, saving the driving source and reducing the lifting cost.

[0041] An extension plate 5 is fixedly mounted on the support plate, and a fan 51 is rotatably mounted on the lower wall of the extension plate 5 . The fan 51 is located directly above the steering bucket 21 , and the fan 51 is connected to the lifting roller 11 through a transmission mechanism 6 .

[0042] The transmission mechanism 6 includes a transmission rod 61 rotatably mounted on the extension plate 5, a bevel gear ring 62 is provided on the transmission rod 61, a bevel gear 63 is provided on the end of the lifting roller 11 close to the transmission rod 61, the bevel gear ring 62 and the bevel gear 63 are engaged with each other, and a second synchronous wheel 64 is provided on the transmission rod 61 and the output shaft of the fan 51, and a second synchronous belt 65 is sleeved between the two second synchronous wheels 64.

[0043] It should also be noted that the present invention provides a fan 51 and a transmission mechanism 6. During the process of transporting the eye shadow pencil to the steering bucket 21, the rotation of the fan 51 can be used to blow air above the steering bucket 21, thereby blowing away the dust on the surface of the eye shadow pencil, thereby cleaning the eye shadow pencil. At the same time, since the fan 51 is driven by the transmission rod 61 through the second synchronous wheel 64 and the second synchronous belt 65, and the transmission rod 61 is driven by the lifting roller 11 through the bevel gear ring 62 and the bevel gear 63, there is no need to provide an additional drive source to achieve the cleaning effect on the eye shadow pencil.

[0044] The present invention can be explained through the following operation mode:

[0045] Before lifting, the eyeshadow pencil is first dropped on the steering plate 24 of the steering bucket 21, so that the eyeshadow pencil drives the steering plate 24 to deflect toward the side with greater weight. During the deflection process, since the control chamber 211 is also deflected toward this side, the weight of the counterweight 212 itself generates a component force in the opposite direction to the elastic force of the first spring 28 on this side, so that the counterweight 212 can slide in the control chamber 211, and further drives the guide wheel 216 to move close to the triangular guide plate 210 through the connecting rod 214 and the second hinge seat 215, and pushes the triangular guide plate 210 to move downward relative to the steering plate 24, so that the abutment plate 26 on this side moves downward and no longer blocks the eyeshadow pencil. The eyeshadow pencil is guided to the inclined guide cylinder 8 through the side guide track 7, and further falls into the transport frame 13 on the lifting belt 12 through the inclined guide cylinder 8, so that the direction in which the eyeshadow pencil falls on the lifting belt 12 is always consistent;

[0046] In the process of the eyeshadow pencil falling from the inclined guide cylinder 8 to the lifting belt 12, the eyeshadow pencil first falls on the discharge port 34 of the discharge plate 33. When there is only one eyeshadow pencil at the discharge port 34, the weight of the eyeshadow pencil is not enough to push the discharge plate 33 down a sufficient distance. At this time, the elastic telescopic arc plate 35 clamps the eyeshadow pencil, and the eyeshadow pencil cannot fall on the lifting belt 12. When the number of eyeshadow pencils at the discharge port 34 increases to two, the weight of the eyeshadow pencil is enough to push the discharge plate 33 down a sufficient distance. At this time, the rack 39 drives the rotating rod 37 to rotate a sufficient angle through the first gear 38, and the rotating rod 37 drives the elastic telescopic arc plate 35 to retract through the second gear 310 and the arc-shaped tooth groove 311, so that the eyeshadow pencil can fall on the lifting belt 12 through the discharge port 34, so that the eyeshadow pencil falls into each transport frame 13 in turn during the transportation process, avoiding the eyeshadow pencil from accumulating on the lifting belt 12 and causing the eyeshadow pencil to slip.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
