Description

Technical Field

[0001] This utility model relates to the field of cosmetic production technology, specifically to a rotary device with adjustable torque. Background Technology

[0002] Some cosmetic packaging materials that require rotation, such as lipsticks and lip balms, consist mainly of two parts: the balm itself and the packaging material. To use them, the balm portion needs to be twisted out, and after use, it must be twisted back into the packaging material. During the manufacturing process of these products, the balm is usually twisted to the bottom of the packaging material before it can be packaged for ease of transport and sale.

[0003] Currently, the paste is screwed into the packaging material using a rotating device. However, existing rotating devices lack torque control. If the screwing torque is too low, the paste will not be completely screwed into the packaging material; if the screwing torque is too high, it will damage the internal thread structure of the plastic packaging material, leading to product defects or scrap. Given these shortcomings, it is necessary to design a rotating device with adjustable torque. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable torque rotating device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable torque rotating device, comprising a base, a drive mechanism mounted on the base, at least one transmission mechanism being drivenly connected to the drive mechanism, the transmission mechanism being disposed on a torque adjusting mechanism, and a packaging material mold base corresponding to the transmission mechanism being disposed on the torque adjusting mechanism.

[0006] Preferably, the drive mechanism includes a drive motor, which is mounted at the bottom of the gearbox. The output end of the drive motor extends upward into the gearbox and a drive gear is mounted on the output shaft of the drive motor.

[0007] Preferably, the transmission mechanism includes a lower magnet and an upper magnet. The lower magnet is mounted on the top of the transmission shaft, and a transmission gear is mounted on the bottom of the transmission shaft. The transmission gear meshes with the drive gear for transmission, and the middle part of the transmission shaft passes through the top of the gearbox via a second bearing.

[0008] Preferably, an upper magnet is provided above the lower magnet and is attracted to the lower magnet by magnetic force. Both the lower magnet and the upper magnet are stepped cylindrical structures. The upper magnet is installed at the bottom of the rotating shaft. The middle part of the rotating shaft is passed through the adjusting plate by a first bearing. A packaging mold base is installed at the top of the rotating shaft.

[0009] Preferably, the torque adjustment mechanism includes an adjustment plate and adjustment components disposed at both ends of the adjustment plate. The adjustment components include an adjustment screw, the bottom of which is rotatably mounted on a shaft support, the shaft support being mounted on a gearbox, and a nut being screwed into the middle of the adjustment screw, the nut being mounted on the adjustment plate.

[0010] Preferably, two spaced-apart sliding sleeves are installed at both ends of the adjusting plate. The sliding sleeves are fitted onto the guide rod. The bottom of the guide rod is installed on the gearbox. The top of the guide rod is connected to a limit plate. A third bearing is installed in the middle of the limit plate. An adjusting screw is threaded through the third bearing. An adjusting handwheel is installed on the top of the adjusting screw.

[0011] Compared with the prior art, the technical solution provided by this utility model has at least the following technical effects or advantages:

[0012] This invention features a torque adjustment mechanism. Rotating the adjustment handwheel drives the adjustment screw, which in turn moves the nut up and down. The nut, in turn, moves the adjustment plate up and down, causing the rotating shaft and upper magnet on the adjustment plate to move accordingly. This allows adjustment of the distance between the lower and upper magnets, thus changing their attraction and consequently adjusting the torque of the rotating shaft to meet the rotation requirements of different packaging materials. When the paste is completely screwed out or into the packaging, the packaging is obstructed and does not rotate, and neither do the upper magnet and rotating shaft. At this time, the torque of the transmission shaft is greater than the attraction force between the lower and upper magnets, causing the lower magnet to rotate. The relative sliding between the upper and lower magnets causes slippage, resulting in insufficient attraction between them to drive the rotating shaft. This prevents excessive torque from being transmitted to the packaging material, thus protecting it from over-rotation and preventing damage due to torque overload. When the cream is not fully screwed into or out of the packaging, the torque of the drive shaft remains constant. The lower and upper magnets are connected by attraction, driving the motor to rotate the drive shaft. The drive shaft transmits torque to the lower magnet, causing the rotating shaft to rotate as well, until the cream is fully screwed into or out of the packaging. This helps control the precision of the cream's rotation. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 and 2 As shown, this utility model provides a technical solution: an adjustable torque rotating device, including a base 1, a drive mechanism 2 installed on the base 1, at least one transmission mechanism 3 connected to the drive mechanism 2, the transmission mechanism 3 being disposed on a torque adjusting mechanism 4, the torque adjusting mechanism 4 being provided with a packaging material mold base 5 corresponding to the transmission mechanism 3, and the packaging material mold base 5 having a contour groove with the same outline as the packaging material.

[0020] The drive mechanism 2 in this embodiment includes a drive motor 201, which is mounted at the bottom of a gearbox 202. The gearbox 202 is mounted on a base 1. An electrical control box is mounted on one side of the base 1. A power switch is mounted on the outer wall of the electrical control box. A controller is mounted inside the electrical control box. The controller is electrically connected to the power switch and the drive motor 201. The output end of the drive motor 201 extends upward into the gearbox 202, and a drive gear 203 is mounted on the output shaft of the drive motor 201.

[0021] In this embodiment, the number of transmission mechanisms 3 is 1-4, preferably 1. The transmission mechanism 3 includes a lower magnet 301 and an upper magnet 302. The lower magnet 301 is installed on the top of the transmission shaft 305. A transmission gear 306 is installed at the bottom of the transmission shaft 305. The transmission gear 306 meshes with the drive gear 203 for transmission. The middle part of the transmission shaft 305 passes through the top of the gearbox 202 through the second bearing 307. The upper magnet 302 is provided above the lower magnet 301 and is attracted to the lower magnet 301 by magnetic force. Both the lower magnet 301 and the upper magnet 302 are stepped cylindrical structures. The upper magnet 302 is installed at the bottom of the rotating shaft 303. The middle part of the rotating shaft 303 passes through the adjusting plate 401 through the first bearing 304. A packaging mold base 5 is installed on the top of the rotating shaft 303. The number of packaging mold bases 5 is 1-4, preferably 1. When the ointment is completely screwed out or into the packaging material, the packaging material is obstructed and does not rotate. The upper magnet 302 and the rotating shaft 303 also do not rotate. At this time, the rotational torque of the transmission shaft 305 is greater than the attraction force between the lower magnet 301 and the upper magnet 302. The relative sliding between the lower magnet 301 and the upper magnet 302 causes slippage, which makes the attraction force between the lower magnet 301 and the upper magnet 302 insufficient to drive the rotating shaft 303 to rotate. This prevents excessive torque from being transmitted to the packaging material, thus avoiding excessive rotation of the packaging material by the rotating shaft 303 and achieving the purpose of protecting the packaging material. This effectively prevents the packaging material from being damaged due to torque overload.

[0022] The torque adjustment mechanism 4 in this embodiment includes an adjustment plate 401 and adjustment components disposed at both ends of the adjustment plate 401. The adjustment components include an adjustment screw 402, the bottom of which is rotatably mounted on a shaft support 403, which is mounted on a gearbox 202. A nut 404 is screwed into the middle of the adjustment screw 402, and the nut 404 is mounted on the adjustment plate 401. Two spaced sliding sleeves 405 are installed at both ends of the adjustment plate 401. The sliding sleeves 405 are sleeved on a guide rod 406. The bottom of the guide rod 406 is mounted on the gearbox 202, and the top of the guide rod 406 is connected to a limit plate 407. A third bearing 408 is installed in the middle of the limit plate 407, and the adjustment screw 402 passes through the third bearing 408. An adjustment handwheel 409 is installed on the top of the adjustment screw 402.

[0023] The working principle of this utility model is as follows: The worker places the packaging material into the contour groove of the packaging material mold base 5, grasps the packaging material, turns on the power switch, and the drive motor 201 drives the drive gear 203 to rotate. The drive gear 203 meshes with the transmission gear 306, driving the transmission gear 306 and the transmission shaft 305 to rotate. The lower magnet 301 also rotates accordingly. The lower magnet 301 and the upper magnet 302 are connected by attraction force, allowing the lower magnet 301 to drive the upper magnet 302 to rotate. The rotating shaft 303 and the packaging material mold base 5 also rotate accordingly, thus allowing the paste to be screwed into or out of the packaging material. This saves time on product screwing in and out, improving work efficiency. During the process of the paste being screwed into or out of the packaging material, when the paste is completely screwed out or into the packaging material, the packaging material is obstructed and does not rotate, and the upper magnet 302 and the rotating shaft 303 also do not rotate. At this time, the transmission... The rotational torque of the drive shaft 305 is greater than the attraction force between the lower magnet 301 and the upper magnet 302. Slippage occurs between the lower magnet 301 and the upper magnet 302, making the attraction force between them insufficient to drive the rotating shaft 303 to rotate. This prevents excessive torque from being transmitted to the packaging material, thus avoiding excessive rotation of the packaging material by the rotating shaft 303 and protecting the packaging material. This effectively prevents damage to the packaging material due to torque overload. When the cream is not completely screwed into or out of the packaging material, the rotational torque of the drive shaft 305 remains unchanged. The lower magnet 301 and the upper magnet 302 are connected by attraction force. The drive motor 201 drives the drive shaft 305 to rotate, and the drive shaft 305 transmits torque to the lower magnet 301. The rotating shaft 303 also rotates until the cream is completely screwed into or out of the packaging material, which helps to control the accuracy of the cream rotation.

[0024] This utility model is equipped with a torque adjustment mechanism 4. By rotating the adjustment handwheel 409, the adjustment screw 402 is driven to rotate. The adjustment screw 402 drives the nut 404 to move up and down. The nut 404 drives the adjustment plate 401 to move up and down. The rotating shaft 303 and the upper magnet 302 set on the adjustment plate 401 also move up and down accordingly, thereby adjusting the distance between the lower magnet 301 and the upper magnet 302. By adjusting the distance between the lower magnet 301 and the upper magnet 302, the attraction force between the lower magnet 301 and the upper magnet 302 is changed, thereby adjusting the torque of the rotating shaft 303 to meet the rotation requirements of different packaging materials.
