[0037] Please refer to Figures 1 to 8 The embodiment of the present application provides a cosmetic packaging bag conveying equipment, which comprises:

[0038] A machine base 1;

[0039] A mounting seat 2 is arranged on the machine base 1;

[0040] The driving roller 3 is rotatably arranged on the mounting base 2.

[0041] The transfer assembly 4 comprises a transfer base 41 and a driven roller 42, the transfer base 41 is horizontally spaced apart from the driving roller 3, and the driven roller 42 is rotatably arranged on the transfer base 41.

[0042] The first conveying assembly 5 comprises a conveying belt 51 and a conveying driving member 52, the conveying belt 51 is connected to the driving roller 3 and the driven roller 42, and is used to carry products, and the conveying driving member 52 is drivingly connected to the driving roller 3, and is used to drive the driving roller 3 to drive the conveying belt 51 to convey the products.

[0043] The transfer driving member 6 is arranged on the mounting base 2, and the output end of the transfer driving member 6 is connected to the transfer base 41, and is used to drive the transfer base 41 to drive the driven roller 42 to move away from or approach the driving roller 3.

[0044] In the embodiment, the cosmetic packaging bag conveying device can be applied to the use of transferring the cosmetic packaging bag products between adjacent two work sections, and the cosmetic packaging bag conveying device comprises a base 1, a mounting base 2, a driving roller 3, a transfer assembly 4, a first conveying assembly 5 and a transfer driving member 6.

[0045] The conveying driving member 52 is used to provide a driving force for driving the driving roller to rotate, the driving roller 3 is used to transmit power to the driven roller 52 through the conveying belt 51, that is, the rotation of the driving roller 3 is driven by the conveying driving member 52, so as to drive the conveying belt 51 connected to the driving roller 3 to move, so that the driven roller 52 connected to the conveying belt 51 rotates, and then the moving conveying belt 51 conveys the cosmetic packaging bag placed on the conveying belt 51.

[0046] The transmission connection between the conveying driving member 52 and the driving roller 3 can be that the output end of the conveying driving member 52 is directly connected to the driving roller 3, or the transmission connection between the conveying driving member 52 and the driving roller 3 can be indirectly connected through an intermediate connecting member, and the intermediate connecting member can be a synchronous pulley, a connecting rod or the like, which is only an example and is not limited.

[0047] When the distance between the adjacent two work sections changes, or when the cosmetic packaging bag conveying device of the utility model is applied between multiple work sections with different distances, the transfer base 41 can be moved according to the distance between the adjacent two work sections, so as to adjust the distance between the driven roller 42 and the driving roller 3, that is, the driven roller 42 is driven to approach or move away from the driving roller 3, so as to change the conveying length of the conveying belt 51, so that the conveying length of the conveying belt 51 can be changed to adapt to the distance between the two adjacent work sections.

[0048] The working process of the cosmetic packaging bag conveying device is as follows:

[0049] After starting, the driving roller 3 drives the conveyor belt 51 to move, for example, to rotate, by the conveying driving member 52, and the conveyor belt 51 carries the cosmetic packaging bag of the upstream section to the downstream section through the driven roller 42.

[0050] When it is necessary to adjust the conveying length to adapt to the distance between different sections, the output end of the transfer driving member 6 can drive the transfer seat 41 to move relative to the mounting seat 2, that is, to drive the driven roller 42 to approach or move away from the driving roller 3, so as to change the relative position of the driven roller 42 and the driving roller 3, and finally make the conveyor belt 51 connected to the driving roller 3 and the driven roller 42 adapt to the spacing between two adjacent sections.

[0051] The cosmetic packaging bag conveying device of the embodiment, by setting the above-mentioned structure of the cosmetic packaging bag conveying device, at least the following effects are realized:

[0052] Firstly, it can flexibly adapt to different section distances. Different sections may have different spacings. The adjustable design of the device enables the packaging bag conveying device to adapt to the spacing between different sections, without the need to separately design different lengths of the conveyor belt 51 to correspond to the spacing between different sections.

[0053] Secondly, it can simplify the production line layout. By automatically adjusting the conveying length, the conveyor belt 51 can be adjusted and shortened when not in use, so as to reduce the space waste of occupied space.

[0054] Thirdly, it can improve the production efficiency. The automatic adjustment function of the device reduces the frequency of manual operation and the time of manual operation, improves the conveying efficiency of the cosmetic packaging bag and the efficiency of adjusting the spacing, and makes the production process more smooth.

[0055] In summary, the cosmetic packaging bag of the utility model effectively solves the problems existing in the adaptability and flexibility of the existing cosmetic packaging bag conveying device by setting the above-mentioned structure, and improves the overall production efficiency and the use convenience of the device.

[0056] In some embodiments, the conveying driving member 52 can be a stepping motor, a servo motor or other driving elements that can provide driving force. Those skilled in the art can design according to actual needs, which is not limited here.

[0057] In some embodiments, the transfer driving member 6 can be a pneumatic cylinder. By connecting the movable piston rod of the pneumatic cylinder to the transfer seat, the intake and exhaust of the pneumatic cylinder are controlled to make the piston rod extend or retract, so as to make the transfer seat 41 move relative to the mounting seat 2.

[0058] Please continue to refer to Figures 1 to 3In some embodiments, the transfer seat 41 is provided with a first sliding structure 100, and the mounting seat 2 is provided with a second sliding structure 200 matched with the first sliding structure 100, and the transfer seat 41 is connected with the mounting seat 2 through the cooperation of the first sliding structure 100 and the second sliding structure 200.

[0059] In the embodiment, the transfer seat 41 is connected with the mounting seat 2 through the cooperation of the second sliding structure 200 and the first sliding structure 100 arranged on the mounting seat 2. For example, the first sliding structure 100 is usually composed of a slide rail or a slide groove 20, and the second sliding structure 200 is a sliding block matched with the slide rail or the slide groove 20. Alternatively, the second sliding structure 200 is provided with a slide rail or a slide groove 20, and the first sliding structure 100 is provided with a sliding block or a sliding element matched with the slide rail or the slide groove 20. Through the cooperation of the first sliding structure 100 and the second sliding structure 200, the transfer seat 41 can move smoothly along the surface of the mounting seat 2.

[0060] When the position of the transfer seat 41 needs to be adjusted, the transfer driving member 6 is started to apply a driving force to the transfer seat 41. The first sliding structure 100 can slide on the second sliding structure 200 under the guidance of the second sliding structure 200, so that the transfer seat 41 can move quickly and smoothly within a certain range to make the driven roller 42 approach or move away from the driving roller, and meet the flexible configuration requirements of different process distances.

[0061] After the sliding adjustment is completed, the transfer seat 41 can be fixed relative to the corresponding position of the mounting seat 2 by stopping the transfer driving member 6 or by other locking devices.

[0062] The cosmetic packaging bag conveying equipment can make the transfer seat 41 and the mounting seat 2 slide relative to each other through the above-mentioned sliding cooperation structure, and realize the following effects, but not limited to:

[0063] Firstly, the flexibility of the system is improved. Since the transfer seat 41 can quickly adjust the position according to different production needs, the cooperation of the first sliding structure 100 and the second sliding structure 200 can significantly improve the adaptability of the whole system to production requirement changes.

[0064] Secondly, through the efficient sliding connection mechanism, the adjustment distance is more simple. The operator does not need to worry about the problems of jamming and wear, and can quickly adjust the position and maintain, and the operation convenience is improved.

[0065] In summary, the close combination of the first sliding structure 100 and the second sliding structure 200 enables the cosmetic packaging bag conveying device to have efficient sliding connection characteristics, greatly improving the flexibility, durability and stability of the device in actual production process, thereby meeting the efficient operation requirements.

[0066] Please continue to refer to Figure 1 and Figure 3 In some embodiments, one of the first sliding structure 100 and the second sliding structure 200 is a sliding rail, and the other is a sliding block that can slide horizontally on the sliding rail.

[0067] In this embodiment, as one of the preferred embodiments of the first sliding structure 100 and the second sliding structure 200, one of the first sliding structure 100 and the second sliding structure 200 can be provided as a sliding rail, and the other can be provided as a sliding block that can slide horizontally on the sliding rail. The horizontal sliding of the sliding block on the sliding rail can enable the transfer seat 41 to slide horizontally relative to the mounting seat 2.

[0068] Specifically, the sliding process of the transfer seat 41 and the mounting seat 2 can be as described in the foregoing embodiments:

[0069] When the transfer seat 41 needs to be adjusted in position, the transfer driving member 6 will be started to push the sliding block to slide horizontally along the sliding rail. This sliding action allows the transfer seat 41 to quickly and smoothly move to a new position to adapt to the distance between different workstations.

[0070] When the transfer seat 41 slides to the desired position, the relative position of the sliding block and the sliding rail is fixed by a mechanical locking device (such as a locking cylinder or a locking block clamp), so that the transfer seat 41 remains stable during subsequent operation and does not displace unexpectedly. The mechanical locking device can be driven by a driving element or locked by a locking clamp by hand. Here, only exemplary examples are given, but not limited.

[0071] In some embodiments, in addition to the combination of sliding rails and sliding blocks, other structural forms can also achieve similar sliding functions, including but not limited to the following structures:

[0072] First, the combination of guide wheels and guide rails. The guide wheels are used as sliding elements and can slide on vertical or horizontal guide rails. The guide rail can be designed as a straight bar, and the guide wheel is in contact with the surface of the guide rail.

[0073] The guide wheel can reduce friction and provide smooth sliding. This design is suitable for devices that need to be frequently moved and adjusted in position, improving flexibility.

[0074] Secondly, the linear bearing set, the linear bearing set generally includes a smooth rod and a ball bearing sleeve sleeved on the smooth rod, for example, the first sliding structure 100 is the smooth rod, and the second sliding structure 200 is the ball bearing sleeve, and the ball bearing sleeve can reciprocate along the extension direction of the smooth rod. The linear bearing set can realize high-precision displacement and is suitable for applications requiring accurate position control. Meanwhile, because rolling friction is used, energy loss and wear are reduced, and the service life of the equipment is prolonged.

[0075] Please continue to refer to Figure 1 and Figure 3 In some embodiments, the mounting seat 2 provided by the embodiment of the utility model is provided with at least one pulley 7, each pulley 7 abuts against the lower side of the moving seat 41, and the moving seat 41 is slidingly connected with the pulley 7.

[0076] In the embodiment, the pulley 7 is a mechanical transmission element, and mainly functions to provide support load and sliding assistance. The contact between the pulley 7 and the moving seat 41 reduces friction, so that the moving seat 41 can slide more smoothly relative to the mounting seat 2. Meanwhile, the design of the pulley 7 can help offset part of the weight of the moving seat 41, so that the pushing or pulling force required in the sliding process is reduced, which can reduce the burden of the moving driving member 6 and improve the overall efficiency.

[0077] When the moving seat 41 needs to be adjusted in position, the moving driving member 6 is started to push the moving seat 41 to move to a target position. Due to the support of the pulley 7, the moving seat 41 can rotate or slide smoothly along the pulley 7 from below, reducing friction and resistance in the moving process. During the entire moving process, the pulley 7 always supports the moving seat 41, ensuring that the moving seat 41 does not tilt or lose stability when sliding.

[0078] The embodiment can achieve the following effects, including but not limited to:

[0079] Firstly, the moving efficiency of the moving seat 41 relative to the mounting seat 2 is improved. Through the design of the pulley 7, the burden required by the moving seat 41 when sliding is reduced, so that the overall moving efficiency is improved.

[0080] Secondly, the friction is reduced. The use of the pulley 7 effectively reduces the direct friction between the moving seat 41 and the mounting seat 2, and reduces the wear.

[0081] In some embodiments, two or more pulleys 7 can be provided. By increasing the number of pulleys 7, the sliding support points of the mounting seat 2 to the moving seat 41 can be correspondingly increased, which is not limited herein.

[0082] In some embodiments, the first sliding structure 100 and the second sliding structure 200 are arranged on the same side wall of the transfer seat 41 and the mounting seat 2, the pulley 7 is arranged on the side of the mounting seat 2 facing the transfer seat 41, the space utilization efficiency can be improved, the floor area of the overall device can be reduced, a more compact mechanical layout can be realized, and the space utilization rate can be improved.

[0083] Please continue to refer to Figure 1 and Figure 3 In some embodiments, the cosmetic packaging bag conveying device provided in the embodiment of the utility model further comprises a tensioning device 8 arranged between the driving roller 3 and the driven roller 42, so as to tension the conveying belt 51.

[0084] In the embodiment, the main function of the tensioning device 8 is to adjust the length and tensioning degree of the conveying belt 51 in the working process, and the basic principle of the tensioning device 8 is to ensure smooth operation of the conveying belt 51 in the working process by adjusting the tension of the conveying belt 51. The tensioning device 8 can be composed of an adjusting rod, a spring, a screw rod or other mechanical structures, and according to different designs, the conveying belt 51 can be tensioned by applying a certain force to prevent it from relaxing or slipping. In this way, the contact between the driving roller 3 and the driven roller 42 can be good, the friction force can be increased, and the driving effect can be improved.

[0085] Before the cosmetic packaging bag conveying device is used, the user can drive the transfer seat 41 to move relative to the mounting seat 2 according to the needs, so that the driven roller 42 approaches or moves away from the driving roller 3, thereby adjusting the length of the conveying belt 51, and then adjusting the tensioning device 8 to set the appropriate tension.

[0086] In the embodiment, the tensioning device 8 with the above structure can bring effects including but not limited to the following aspects:

[0087] First, the transmission efficiency is improved: the proper tension of the conveying belt 51 can ensure sufficient friction force between the conveying belt 51 and the roller, improve the conveying efficiency of the conveying belt 51, and avoid sliding.

[0088] Second, the product stability is ensured: the tensioning device 8 can effectively prevent the excessive relaxation of the conveying belt 51, so that the product transmission in the conveying process is more stable, and product damage caused by improper conveying is avoided.

[0089] Preferably, please continue to refer to Figure 1 and Figure 3 In some embodiments, the tensioning device 8 provided in the embodiment of the utility model comprises a first tensioning roller 81 and a second tensioning roller 82 arranged at intervals on the mounting seat 2, and a idler 83 arranged between the first tensioning roller 81 and the second tensioning roller 82;

[0090] The conveying belt 51 is annular and sequentially wound around the driving roller 3, the first tensioning roller 81, the idler 83, the second tensioning roller 82 and the driven roller 42. The driving roller 3, the driven roller 42, the idler 83 and the second tensioning roller 82 abut the inner side of the conveying belt 51, and the first tensioning roller 81 abuts the outer side of the conveying belt 51.

[0091] In this embodiment, the principle of the tensioning device 8 is mainly based on providing uniform tension and stable friction force through the arrangement of multiple tensioning rollers. The conveying belt 51 is annular and sequentially wound around the driving roller 3, the first tensioning roller 81, the idler 83, the second tensioning roller 82 and the driven roller 42. The first tensioning roller 81 abuts the outer side of the conveying belt 51 and applies tension to the conveying belt 51 by exerting an external force. The idler 83 serves as an intermediate support point, balances the tension of the conveying belt 51 and ensures the stability of the conveying belt 51 during use. The second tensioning roller 82, similar to the first tensioning roller 81, provides additional support for the tensioning of the conveying belt 51, and the inner side of the conveying belt 51 contacts the driving roller 3 and the driven roller 42 to enhance the friction force.

[0092] Initial conveying belt 51 adjustment: Before starting the device, the first tensioning roller 81 and the second tensioning roller 82 will adjust their positions through mechanical structures, so that the conveying belt 51 runs in a tensioned state.

[0093] Tensioning process: When the device starts, the driving roller 3 rotates to drive the conveying belt 51 to move, the first tensioning roller 81 limits the relaxation of the conveying belt 51 by exerting force, and the idler 83 helps to disperse the tension to maintain the conveying belt 51 at an appropriate tension level.

[0094] Dynamic adjustment: During the conveying process, if a change in tension is identified, the mechanical device can automatically adjust the position of the first tensioning roller 81 to maintain appropriate tension and friction force, ensuring smooth operation of the conveying belt 51.

[0095] When it is necessary to adjust the conveying length of the cosmetic packaging bag conveying device, the load moving driving member 6 can be driven to move the load seat 41 away from or close to the driving roller 3, so that the distance between the driven roller 42 and the driving roller 3 increases or decreases. After the distance between the driving roller 3 and the driven roller 42 is adjusted, the conveying belt 51 can be sequentially wound around the driving roller 3, the first tensioning roller 81, the idler 83, the second tensioning roller 82 and the driven roller 42, and the first tensioning roller 81, the second tensioning roller 82 and the idler 83 tension the conveying belt 51.

[0096] Please continue to refer to Figures 3 to 5, as the preferred setting of the tensioning device 8 in the above-mentioned embodiments, in some embodiments, the tensioning device 8 proposed in the embodiment of the utility model still includes a third tensioning roller 84, the third tensioning roller 84 is arranged on the moving seat 41 and located between the idler 83 and the second tensioning roller 82, the conveying belt between the second tensioning roller 82 and the driven roller 42 is also arranged on the third tensioning roller 84, and the third tensioning roller 84 abuts against the outer side of the conveying belt 51.

[0097] In this embodiment, first, the third tensioning roller 84 is used to adjust the length of the conveying belt 51, and specifically, please refer to Figure 4 and Figure 5 , Figure 4 and Figure 5 is the state of the device in the initial state, the segment of the conveying belt 51 between the driving roller 3 and the driven roller 42 for carrying and transporting the packaging bag is called the first interval 51A of the conveying belt 51, and the segment of the conveying belt 51 between the third tensioning roller 84 and the second tensioning roller 82 is called the second interval 51B of the conveying belt 51, in the initial state, the driven roller 42 is in the state of not moving, and the third tensioning roller 84 is close to the idler 83 at this time, when adjusting the conveying distance of the cosmetic packaging bag conveying device of the utility model, referring to Figure 2 and Figure 3 , the moving drive 6 drives the moving seat 41 to drive the driven roller 42 and the third tensioning roller 84 away from the driving roller 3, so that the distance between the driving roller 3 and the driven roller 42 becomes larger, the span of the first interval 51A of the conveying belt 51 becomes larger, and at the same time, the distance between the third tensioning roller 84 and the second tensioning roller 82 is shortened, that is, the span of the second interval 51B of the conveying belt 51 becomes smaller.

[0098] By arranging the above-mentioned third tensioning roller 84, the tensioning device 8 of the cosmetic packaging bag conveying device of the utility model realizes the following effects:

[0099] First, it is not necessary to change the length of the conveying belt 51 according to the adjustment of the conveying distance of the cosmetic packaging bag conveying device of the utility model, the length of the conveying belt 51 can automatically adapt to the change of the conveying distance within a certain interval, which saves the cumbersome conveying disassembly and assembly steps and saves labor.

[0100] Second, the system robustness is enhanced: in the case of load fluctuation or impact, the additional tensioning support point enhances the adaptability of the system to the change of tension, avoiding the slipping or breaking of the conveying belt 51 due to uneven tension.

[0101] In summary, the design of the third tensioning roller 84 in this embodiment further enhances the function of the tensioning device 8, provides higher tensioning force and more stable working state, and finally improves the transmission efficiency and reliability of the entire cosmetic packaging bag conveying device.

[0103] In the embodiment, the sliding connection between the first tensioning roller 81 and the mounting seat 2 allows the first tensioning roller 81 to move horizontally on the mounting seat 2 relative to the mounting seat 2, so as to adjust the distance between the first tensioning roller 81 and the second tensioning roller 82, that is, to adjust the initial distance and the tensioning force between the two tensioning rollers. The adjustment can be that the first tensioning roller 81 is driven to move in the direction towards the driving roller 3 or the driven roller 42 by a motor or a manual device, so as to adjust the tensioning degree of the conveying belt 51.

[0104] In actual operation, the working process of the adjusting device 9 can be divided into the following steps:

[0105] Initial setting: when the equipment is installed, the position of the first tensioning roller 81 is set according to the length and initial state of the conveying belt 51. At this time, the adjusting device 9 is in an idle state.

[0106] In the conveying process, if it is found that the tension of the conveying belt 51 is insufficient or too tight, the conveying is stopped, and the operator can fine-tune the position of the first tensioning roller 81 through the adjusting device 9. According to the need, the moving direction of the first tensioning roller 81 towards the driving roller 3 or the driven roller 42 is selected, and the tensioning force is appropriately adjusted.

[0107] In some embodiments, the tension state of the conveying belt 51 can also be monitored by a sensor, and the adjusting device 9 can automatically adjust to maintain the optimal working state.

[0108] Through the adjusting device 9 with the above structure, the following effects can be achieved, including but not limited to:

[0109] Firstly, the tensioning force can be adjusted to ensure that the conveying belt 51 is always in the best tensioning state, and the slippage or wear of the conveying belt 51 caused by insufficient tension is avoided.

[0110] Secondly, the flexibility of the equipment is enhanced, and the adjusting device 9 improves the adaptability of the equipment under different products and operating conditions through simple operation.

[0111] In summary, the adjusting device 9 of the embodiment brings higher flexibility and operability to the cosmetic packaging bag conveying device, ensures a continuous and stable conveying process, and improves the overall performance.

[0112] Please continue to refer toFigure 8 In some embodiments, as one of the preferred settings of the connection mode of the first tensioning roller 81 and the mounting base 2, the opposite two side walls of the mounting base 2 are provided with sliding grooves 20, which are used to accommodate the two connecting ends of the first tensioning roller 81. The two connecting ends of the first tensioning roller 81 are respectively connected to the two sliding grooves 20.

[0113] In this embodiment, the opposite two side walls of the mounting base 2 are respectively provided with sliding grooves 20, which are pre-processed through grooves during the manufacturing of the mounting base 2, and have a certain length to accommodate the two connecting ends of the first tensioning roller 81. The connecting ends of the first tensioning roller 81 are accurately processed to match the size and shape of the sliding grooves 20, so that they can rotate and slide in the sliding grooves 20. The sliding grooves 20 can be designed to have a certain guiding function, such as a groove or other structure, so that the first tensioning roller 81 does not deviate when sliding, ensuring stable operation.

[0114] During the adjustment process, the specific steps are as follows:

[0115] After the equipment is installed, the operator can pre-adjust the position of the first tensioning roller 81 according to the needs, so that it is located in the appropriate position, so that the conveying belt 51 is in the appropriate tension state.

[0116] When the equipment is running, if it is found that the conveying belt 51 is insufficient or too tight, the operator can adjust the position of the first tensioning roller 81, and drive the first tensioning roller 81 in the sliding groove 20 to slide through manual or mechanical means (such as an electric sliding device). If you need to increase the tension, the operator will slide the first tensioning roller 81 towards the driving roller 3, and tighten the conveying belt 51. If you need to reduce the tension, adjust the first tensioning roller 81 to the direction of the driven roller 42, and loosen the tension of the conveying belt 51. Or introduce a sensor to monitor the real-time tension of the conveying belt 51, and the system can automatically control the movement of the first tensioning roller 81 in the sliding groove 20 to keep the tension within the set range.

[0117] Through the above structure of the connection design of the first tensioning roller 81 and the mounting base 2, the following effects can be achieved, including but not limited to:

[0118] First, through the design of the sliding groove 20, the adjustment process of the first tensioning roller 81 is quick and convenient, and the operator can complete the adjustment of the first tensioning roller 81 in a short time.

[0119] Second, the stability is increased, and the sliding groove 20 can effectively prevent the first tensioning roller 81 from tilting or deviating during the movement, ensuring the accuracy and stability of the adjustment.

[0120] Please continue to refer to Figure 8As one of the preferred settings of the adjusting device 9, in some embodiments, the adjusting device 9 proposed by the embodiments of the present application comprises at least one connecting piece 91 and at least one adjusting driving piece 92, the adjusting driving piece 92 is in driving connection with the first tensioning roller 81 through the connecting piece 91, so as to drive the connecting piece 91 to drive the first tensioning roller 81 to move in the direction towards the driving roller 3 or in the direction towards the driven roller 42.

[0121] In the embodiments, the working principle of the adjusting device 9 is based on the power applied by the adjusting driving piece 92, the power is transmitted to the first tensioning roller 81 through the connecting piece 91, so as to adjust the position of the first tensioning roller 81 relative to the mounting base 2. The adjusting driving piece 92 can be an electric motor, a pneumatic cylinder or other driving device, which is responsible for generating sufficient power to push the connecting piece 91. The connecting piece 91 serves as an intermediate connecting piece 91 between the adjusting driving piece 92 and the first tensioning roller 81, and transmits the power applied by the driving piece to the first tensioning roller 81, so as to drive the first tensioning roller 81 to move in the direction towards the driving roller 3 or in the direction towards the driven roller 42. By moving the relative position of the first tensioning roller 81, the tension of the conveying belt 51 is adjusted.

[0122] For example, the adjusting driving piece 92 can also be a nut, and the connecting piece 91 is a screw rod screwed with the structure provided on the mounting base 2. By rotating the nut, the screw rod is moved relative to the mounting base 2, so that the first tensioning roller 81 is moved relative to the mounting base 2 (the sliding groove 20).

[0123] In actual operation, the steps of the adjusting device 9 are as follows:

[0124] After the equipment is installed, the adjusting device 9 will be set to the initial state, so as to ensure that the first tensioning roller 81 is located at a position where the conveying belt 51 is in a proper tension degree.

[0125] During the operation of the equipment, if it is detected that the tension of the conveying belt 51 is insufficient or excessive, the operator can stop the machine to adjust the position of the first tensioning roller 81 to change the tension of the conveying belt 51. For example, the first tensioning roller 81 is moved towards the driving roller 3 to increase the tension of the conveying belt 51. The adjusting driving piece 92 will generate a pushing force to make the connecting piece 91 drive the first tensioning roller 81 to move in the direction of the driving roller 3, so as to tighten the conveying belt 51; or the first tensioning roller 81 is moved towards the driven roller 42 to relax the tension of the conveying belt 51. The adjusting driving piece 92 will make the first tensioning roller 81 move in the direction of the driven roller 42 through the reverse force, so as to restore the proper tension of the conveying belt 51; or the tension of the conveying belt 51 is monitored in real time by the sensor as described in the foregoing embodiments, and the adjusting driving piece 92 can automatically adjust the position of the first tensioning roller 81 relative to the driving roller 3 (the driven roller 42) according to the real-time data.

[0126] In summary, the adjusting device 9 realizes effective control of the first tensioning roller 81 through the cooperation of the connecting piece 91 and the adjusting driving piece 92, improves the flexibility and efficiency of the conveying belt 51 tensioning management, and provides guarantee for stable operation of the cosmetic packaging bag conveying equipment.
