Description

Technical Field

[0001] This invention relates to a portable PROTOS-M8 VARIOS chain plate replacement device, belonging to the technical field of chain plate replacement tools for tobacco warehouses. Background Technology

[0002] The PROTOS-M8 cigarette rolling machine is equipped with a cigarette storage chamber consisting of multiple turntables, supports, and chain plates. The chain plates in the cigarette storage chamber drive the cigarettes produced by the cigarette rolling machine to move forward, serving to temporarily store and transport the cigarettes.

[0003] In cigarette machine maintenance, the wear condition of the cigarette storage chain plates is checked to ensure timely replacement of those that meet the replacement criteria. Current methods for replacing cigarette storage chain plates mostly require manual labor. With the VARIOS chain plates fully relaxed, all nine old chain plates that need replacement are manually removed section by section, and then the new chain plates are threaded into the VARIOS chain plate track to complete the replacement. Because this is purely manual removal and threading of the chain plates, the work is not only inefficient but also physically demanding. Currently, the cigarette storage chain plate replacement process requires six workers, often takes more than six hours, and the work environment is on a platform three meters above the ground, posing significant safety hazards.

[0004] Therefore, there is an urgent need to provide a new type of chain plate replacement device to effectively solve the related drawbacks of the existing technology. Utility Model Content

[0005] The purpose of this invention is to provide a portable PROTOS-M8 VARIOS chain plate replacement device, which aims to achieve convenient replacement of tobacco warehouse chain plates by simultaneously unloading the old chain plate and rotating the new chain plate.

[0006] To solve the above-mentioned technical problems, this utility model is implemented using the following technical solution:

[0009] The lifting plate is positioned above the base via the support arm assembly, and the support arm assembly is rotatably connected to both the base and the lifting plate. The pull rod assembly is positioned on one side of the base and is rotatably connected to both the base and the lifting plate, and is used to drive the mounting base mounted on the lifting plate to detach from or contact the ground according to its own rotation direction. The casters are mounted on the corner areas of the lower end face of the base.

[0010] The chain plate docking mechanism includes: a chain output gear, a support assembly, a rotating shaft, and a drive motor;

[0011] The drive motor is mounted on the top of the mounting base via a first support; one end of the rotating shaft is connected to the output end of the drive motor, and the other end is equipped with the output gear; one end of the support assembly is fixedly connected to the mounting base, and the other end is sleeved on the rotating shaft via a mounting plate, for supporting the output gear to make a transmission connection with the old chain plate.

[0012] This invention enables quick and convenient replacement of the VARIOS chain plates on the PROTOS-M8 equipment through a cleverly designed lifting mechanism, mounting base, and chain plate docking mechanism. The lifting mechanism ensures height adjustability and device mobility during operation, while the chain plate docking mechanism guarantees the continuity and stability of transmission between the old chain plate and the output gear. The entire device has a simple structure, is easy to operate, and significantly improves production efficiency and ease of equipment maintenance.

[0013] Optionally, the pull rod assembly includes a pull rod, a first connector, a second connector, and a rotating rod;

[0014] The pull rod is rotatably mounted on one side of the lifting plate and is rotatably connected to the rotating rod through the first connector; the second connector is located below the first connector, with one end fixed to one side of the base and the other end rotatably connected to the rotating rod.

[0015] Optionally, the support assembly includes a support frame and a second support base, the second support base being fixedly connected to the top of the mounting base; the support frame includes two downward-facing inverted V-shaped steel frames, the inverted V-shaped steel frames being detachably connected to the second support base. This detachable connection design ensures that the spacing between the inverted V-shaped steel frames can be adaptively adjusted according to actual working conditions.

[0016] Optionally, two chain plate baffles can be detachably installed on the second support base, and the chain plate baffles are symmetrically distributed relative to the output gear. These baffles are used to correct and position the moving old chain plate and to protect the rotating output gear. Similarly, since the chain plate baffles can also be detachably installed on the second support base, their applicability can be specifically expanded when dealing with wide-sized old chain plates to meet actual working conditions.

[0017] Optionally, the support arm assembly includes a plurality of support arms, which are symmetrically arranged in pairs on both sides of the base and the lifting plate, with one end of each support arm rotatably connected to the base and the other end rotatably connected to the lifting plate.

[0019] Optionally, the mounting base includes: a base frame, a drawer, and a support rod; the drawer is installed at the bottom of the base frame for storing tools; the support rod is located at the four corners of the bottom of the base frame for providing stable support when the output gear is connected to the old chain plate drive.

[0020] Optionally, the length of the support rod is greater than the distance between the top of the lifting plate and the bottom of the caster wheel when the lifting plate contacts the base; the upward displacement distance of the lifting plate is greater than the distance between the caster wheel and the ground when the lifting plate contacts the base.

[0023] Optionally, the drive motor is a servo motor.

[0024] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0025] Addressing the technical drawbacks of large volume, heavy weight, and numerous old chain plates in tobacco storage facilities, which result in high manpower requirements, low labor efficiency, high risks, and long replacement times, this utility model utilizes the coordinated operation of a lifting mechanism, a mounting base, and a chain plate docking mechanism. After the chain-output gear in the docking mechanism meshes with the target old chain plate, a drive motor replaces manual operation, causing the old chain plate and the new chain plate, which are integrated with the chain-output gear, to move forward synchronously. This effectively achieves simultaneous unloading of the old chain plate and reinstallation of the new chain plate. This process not only reduces the labor intensity of workers but also effectively improves the overall efficiency of chain replacement. Attached Figure Description

Detailed Implementation

[0031] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention. Example

[0032] This embodiment introduces a movable PROTOS-M8 VARIOS chain plate replacement device, which includes: a lifting mechanism 1, a mounting base 2, and a chain plate docking mechanism 3.

[0033] The lifting mechanism 1 includes: a base 4, a support arm assembly, a lifting plate 5, a pull rod assembly, and casters 6;

[0034] The lifting plate 5 is positioned above the base 4 via the support arm assembly, and the support arm assembly is rotatably connected to both the base 4 and the lifting plate 5. The pull rod assembly is positioned on one side of the base 4 and is rotatably connected to both the base 4 and the lifting plate 5, and is used to rotate to cause the mounting base 2 mounted on the lifting plate 5 to detach from or contact the ground. The casters 6 are mounted on the corner areas of the lower end face of the base 4.

[0035] The chain plate docking mechanism 3 includes: a chain output gear 7, a support component 8, a rotating shaft 9, and a drive motor 10. The chain output gear 7 is a gear of the same model as the drive gear of the VARIOS chain plate drive motor, and the drive motor 10 is a motor of the same model as the VARIOS drive motor.

[0036] The drive motor 10 is mounted on the top of the mounting base 2 via the first support 11; one end of the rotating shaft 9 is connected to the output end of the drive motor 10, and the other end is equipped with the output gear 7; one end of the support assembly 8 is fixedly connected to the mounting base 2, and the other end is sleeved on the rotating shaft 9 via the mounting plate 12, for supporting the output gear 7 to transmit power to the old chain plate. The output gear 7 can be fixedly connected to the rotating shaft 9 via a key, and both ends of the rotating shaft 9 are rotatably connected to the mounting plate 12 via bearings.

[0037] In practical application, by pulling the pull rod assembly downwards, the mounting base 2 installed on the lifting plate 5 will rise accordingly based on the connection relationship of the relevant components. At this state, the mounting base 2 is at its highest position, and the device transitions from four casters 6 to sliding support. Furthermore, the flexible control of the casters 6 enables the portable movement of the entire device until the mounting base 2 and the chain plate docking mechanism 3 mounted on the mounting base 2 are moved to the target replacement position. Then, the pull rod assembly can be pulled upwards, allowing the mounting base 2 to be lifted. The mounting base 2 and the chain plate docking mechanism 3 are lowered smoothly. At this time, the mounting base 2 provides support to ensure the stability of the device during the replacement operation. After the device is stabilized, the old chain plate is disassembled, and the head of the old chain plate is engaged with the output gear 7 in the chain plate docking mechanism 3. At the same time, the tail of the old chain plate is connected to the head of the new chain plate. Then, the drive motor 10 is started to slowly drive the output gear 7 to rotate until the head of the new chain plate moves to engage with the output gear 7. After the old chain plate is unloaded, the head and tail of the new chain plate are finally connected, thus realizing the simultaneous operation of unloading the old chain plate and reinstalling the new chain plate. Example

[0038] refer to Figures 1 to 4 Based on Example 1, this example also has the following design:

[0039] The pull rod assembly includes a pull rod 13, a first connector 14, a second connector 15, and a rotating rod 16;

[0040] The pull rod 13 is rotatably mounted on one side of the lifting plate 5 and is rotatably connected to the rotating rod 16 via the first connecting member 14. The second connecting member 15 is disposed below the first connecting member 14, with one end fixed to one side of the base 4 and the other end rotatably connected to the rotating rod 16. The second connecting member 15 includes two rotating rod mounting plates, with a pull rod drive shaft between the two mounting plates. The rotating rod is connected to the two rotating rod mounting plates via this pull rod drive shaft.

[0041] The support assembly includes a support frame and a second support base 17, the second support base 17 being fixedly connected to the top of the mounting base 2; the support frame includes two downward-facing inverted V-shaped steel frames 18, the inverted V-shaped steel frames 18 being detachably connected to the second support base 17.

[0042] Two chain plate baffles 19 can also be detachably installed on the second support base 17, and the chain plate baffles 19 are symmetrically distributed relative to the output gear 7, which are used to correct and position the moving old chain plate and to protect the rotating output gear 7.

[0043] It is worth noting that the detachable design of the aforementioned inverted V-shaped steel frame 18 and chain plate baffle 19 is intended to allow for targeted adjustment of the width of the inverted V-shaped steel frame 18 and / or chain plate baffle 19 according to the different sizes of the old chain plates in the tobacco storage facility during practical applications. This expands the applicability of the device. Furthermore, the detachable connection method facilitates the storage and placement of related components, enhancing its practicality. In addition, the drive motor 10 and the first support base 11, as well as the first support base 11 and the mounting base 2, are also fixedly connected in a detachable manner, facilitating the portable storage of the tobacco storage chain plate replacement device.

[0044] The support arm assembly includes several support arms 20, and in this embodiment, six support arms 20 are specifically selected. The support arms 20 are symmetrically arranged in pairs on both sides of the base 4 and the lifting plate 5, and one end of the support arm 20 is rotatably connected to the base 4, and the other end is rotatably connected to the lifting plate 5.

[0045] At least one limiting block 21 is provided on the upper surface of the base 4 near the corner of the pull rod assembly. In this embodiment, only one limiting block 21 is provided at one corner to limit the rotation angle of the support arm 20. In practical applications, when the corresponding rotating rod 16 is rotated downwards, the mounting base 2 can be stabilized at a position such as... Figure 1 The support rod shown is off the ground, which facilitates the flexible movement of the device.

[0046] The mounting base 2 includes: a base frame 22, a drawer 23, and a support rod 24; the bottom surface of the base frame 22 is fixedly connected to the lifting plate 5; the drawer 23 is installed at the bottom of the base frame 22 for storing tools; the support rod 24 is located at the four corners of the bottom of the base frame 22 to provide stable support when the chain gear 7 is connected to the old chain plate.

[0047] refer to Figure 1 and Figure 2As can be seen from the replacement device in the movable and stable states shown, the length of the support rod 24 is greater than the distance between the top of the lifting plate 5 and the bottom of the caster wheel 6 when the lifting plate 5 contacts the base 4; the upward displacement distance of the lifting plate 5 is greater than the distance between the caster wheel 6 and the ground when the lifting plate 5 contacts the base 4.

[0048] The centerline of the output gear 7 is on the same straight line as the centerline of the rotating shaft 9.

[0049] In addition, the VARIOS chain plate changing device of the portable PROTOS-M8 also includes a speed controller for adjusting the speed setting of the drive motor 10 according to actual working conditions. The drive motor 10 can be selected as a servo motor.

[0050] In practical application, this embodiment first involves pulling down the rotating rod 16 to raise the lifting plate 5, causing the support rod 24 of the mounting base 2 to leave the ground. Supported by four casters 6, the tobacco storage chain plate replacement device is moved to the target replacement position. Then, the rotating rod 16 is pulled upwards to stabilize the device on the ground. Next, the old chain plate is disassembled, and its head is engaged with the output gear 7. Simultaneously, the tail of the old chain plate is connected to the head of the new chain plate. Further, the drive motor 10 is started to rotate the output gear 7, causing the old chain plate to slowly move to the right side of the tobacco storage chain plate replacement device. The operating speed of the drive motor 10 can be set to VARIOS. The system operates at a rotation speed of 10,000 cigarettes per minute (the chain conveyor speed is 10,000 cigarettes per minute). The old chain plates that are moved out are manually placed and packed. After about 20 minutes, all the old chain plates that need to be replaced will be pulled out until the new chain plates are pulled out to the corresponding position of the VARIOS chain plate drive motor 10. At this time, the drive motor 10 is turned off. Finally, the head and tail of the new chain plate are connected.

[0051] After the new chain plate is connected, manually tension it again to reach the set tension value. Then, turn off manual mode and turn on automatic operation mode. The VARIOS tension detection motor will recalculate the tension value and balance the tension at both ends of the chain plate. The entire VARIOS system can then proceed to the next stage of commissioning. After 30 minutes of commissioning, the entire chain plate replacement process is complete.

[0052] This embodiment reduces the number of segmented cutting operations on the tobacco storage chain plates by modifying the construction method. In actual production activities, after three complete tobacco storage chain plate replacement projects, the average time for the complete tobacco storage chain plate replacement process was calculated as follows: opening the old tobacco storage chain plate connecting section (5 minutes), connecting the new tobacco storage chain plate to the old tobacco storage chain plate (5 minutes), removing the old tobacco storage chain plate using the replacement device, and simultaneously reinstalling the new tobacco storage chain plate (20 minutes), connecting the head and tail of the new tobacco storage chain plate (5 minutes), and debugging and operation (30 minutes), for a total of 65 minutes. Therefore, the entire replacement process not only saves manpower and reduces labor intensity but also effectively reduces the safety risks of maintenance work.
