Description

Technical Field

[0001] The utility model relates to the technical field of automatic control, in particular to a device for detecting the roll diameter of a finished film roll. Background Art

[0002] A finished film roll diameter detection device is a device used to monitor the diameter changes of the roll core in real time during the film rolling process to ensure that the finished film roll reaches the required specifications and dimensions. The working principle of this device is to monitor the changes in the roll diameter in real time during the film rolling process, thereby improving production efficiency and product quality, reducing the need for manual inspection, and realizing automatic control.

[0003] The existing Chinese patent (publication number CN209783515U) discloses a device for detecting the roll diameter of a finished film roll. First, the first bracket is lifted up by a lifting cylinder, driving the pressure roller to rise along the guide rail and press the roll core, and then the drive motor is started to rotate the roll core and start rolling the film. At this time, the pressure roller retreats in the opposite direction on the guide rail as the roll diameter continues to increase, driving the resistive displacement sensor for detection. After the film is rolled, the drive motor is turned off. At the same time, the resistive displacement sensor obtains the detection result and sends it to the PLC.

[0004] Although the above patent has achieved the detection of the roll diameter of the film to a certain extent, in actual use, although the cylinder can provide greater force, the force adjustment is not as precise as the hydraulic system. Since the above patent uses PLC to control the increase of the pressure of the lifting cylinder, the cylinder is not easy to stop and remain stable at any position in the stroke, and the installation and maintenance of a cylinder system is more expensive and requires more space than using other types of drive systems. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings in the prior art and provide a device for detecting the roll diameter of a finished roll film.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a finished film roll diameter detection device, comprising a connecting bin, both sides of which are provided with sliding grooves, and a transmission assembly is arranged on the connecting bin;

[0007] The transmission assembly includes a tooth block, which is fixedly connected in a sliding groove on the connecting bin, a driven gear meshingly connected to the tooth block, a rotating rod clamped on the driven gear, a transmission rope transmission-connected to the rotating rod, and a driving gear transmission-connected on the side of the transmission rope away from the tooth block.

[0008] As a preferred embodiment, one of the two driving gears is fixedly connected to a driving motor, a bracket is fixedly connected to the driving motor, and the bracket on the driving motor is slidably connected to the inner wall of the connecting bin.

[0009] The technical effect of adopting the above further scheme is: by setting a driving motor, it is convenient to drive the driving gear to rotate, thereby realizing transmission to the driven gear. The driven gear then rolls upward on the tooth block on the sliding groove on the connecting bin. When the driven gear drives the rotating rod to rise, the transmission rope will be tightened to prevent the driven gear from being out of meshing with the driving gear.

[0010] As a preferred embodiment, among the two sliding grooves on the connecting bin, a gripping plate is slidably connected to the sliding groove on the side away from the driving motor, the gripping plate is fixedly connected to the rotating rod, a fixing block is provided on the gripping plate, the fixing block on the gripping plate is fixedly connected to the driven gear and in contact with the rotating rod, a snap-in groove is provided on the gripping plate, and a snap-in block is provided on the driven gear.

[0011] The technical effect of adopting the above further scheme is: by providing a gripping plate, the gripping plate can be fixedly connected to the driven gear through a fixing block. When in use, the gripping plate is pulled to make the rotating rod slide out of the sliding groove on the connecting bin, so that the rotating rod can be removed. By providing a snap-in groove and a snap-in block, the rotating rod can be rotated when the gear rotates, and the gripping plate can prevent the rotating rod from slipping off the driven gear.

[0013] The technical effect of adopting the above further solution is: by setting a sliding block on the resistance sensor, when the roll film on the rotating rod gradually rolls thicker, it will drive the sliding block on the resistance sensor to move, thereby realizing the detection of its roll diameter.

[0014] As a preferred implementation, the three resistance sensors are all fixedly connected with connecting wires.

[0015] The technical effect of adopting the above further scheme is: by providing connecting wires to connect the three resistance sensors, the series connection of the resistance sensors can be realized, so that the resistance sensors can be conveniently connected to the display screen when in use, and even if one resistance sensor is damaged, the remaining resistance sensors will supplement the missing values ​​on average, avoiding the problem of individual damage of the resistance sensors, which will lead to too large deviation in the measurement value of the roll diameter.

[0016] As a preferred implementation manner, the bottom of the rotating rod is rotatably connected to a bottom tray, and a connecting rod is fixedly connected to the bottom tray.

[0017] The technical effect of adopting the above further solution is that by providing a bottom tray, additional supporting force is provided for the rotating rod.

[0018] As a preferred implementation, both ends of the connecting rod are slidably connected to the driven gear.

[0019] The technical effect of adopting the above further solution is: preventing the driven gear from driving the connecting rod to rotate

[0020] As a preferred embodiment, a tensioning roller is rotatably connected to the connecting bin, and a sliding roller is slidably connected to the connecting bin.

[0021] The technical effect of adopting the above further solution is: by providing a tensioning roller and a sliding roller, the rolled film can be fixed and tightened to prevent it from being rolled too loosely when rolled onto the rotating rod, thereby affecting the detection result.

[0022] Compared with the prior art, the advantages and positive effects of the utility model are:

The driven gear is clamped on the rotating rod. The rotating rod is in turn connected to another driven gear, which is in turn connected to the driving gear. One of the driving gears is fixedly connected to a driving motor, and the driving motor is slidably connected to the inner wall of the connecting bin through a bracket. When the driving motor is working, it can drive the driving gear to rotate, thereby driving the driven gear to roll on the tooth block, so that the rotating rod rises, the transmission rope is tightened, and the meshing state between the gears is maintained, thereby realizing the lifting of the rotating rod. The motor has high controllability, realizes automatic winding diameter detection, reduces manual intervention, improves detection efficiency, and avoids the problem of using a cylinder for lifting, and it is difficult to stop and maintain stability at any position in the stroke.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] like Figures 1 to 5 As shown, this embodiment provides a technical solution, a device for detecting the roll diameter of a finished roll film, comprising a connecting bin 1, sliding grooves are provided on both sides of the connecting bin 1, and a transmission assembly 2 is provided on the connecting bin 1;

[0033] like Figures 1 to 4 As shown, the transmission assembly 2 includes a tooth block 21, the tooth block 21 is fixedly connected in a sliding groove on the connecting bin 1, the tooth block 21 is meshed with a driven gear 22, the driven gear 22 is clamped with a rotating rod 26, the rotating rod 26 is transmission-connected with a transmission rope 29, and the transmission rope 29 is transmission-connected with a driving gear 23 on the side away from the tooth block 21;

[0034] like Figures 1 to 4As shown, a transmission assembly 2 is provided, including a tooth block 21, a driven gear 22, a rotating rod 26 and a driving gear 23. The tooth block 21 is fixed in the sliding groove of the connecting bin 1 and meshes with the driven gear 22. The driven gear 22 is clamped on the rotating rod 26. The rotating rod 26 is in turn connected to another driven gear 22 in transmission connection. This driven gear 22 is in turn connected to the driving gear 23 in transmission connection. One of the driving gears 23 is fixedly connected to a driving motor 28. The driving motor 28 is slidably connected to the inner wall of the connecting bin 1 through a bracket. When the driving motor 28 is working, it can drive the driving gear 23 to rotate, thereby driving the driven gear 22 to roll on the tooth block 21, so that the rotating rod 26 rises, tightens the transmission rope 29, and maintains the meshing state between the gears, thereby realizing the lifting of the rotating rod 26. The motor has high controllability, realizes automatic winding diameter detection, reduces manual intervention, improves detection efficiency, and avoids the problem of using a cylinder for lifting, and it is not easy to stop and maintain stability at any position in the stroke.

[0035] Further, such as Figure 3 As shown, one of the two driving gears 23 is fixedly connected to a driving motor 28, and a bracket is fixedly connected to the driving motor 28. The bracket on the driving motor 28 is slidably connected to the inner wall of the connecting bin 1. By setting the driving motor 28, it is convenient to drive the driving gear 23 to rotate, so as to realize the transmission of the driven gear 22. The driven gear 22 then rolls upward on the tooth block 21 on the sliding groove on the connecting bin 1. When the driven gear 22 drives the rotating rod 26 to rise, the transmission rope 29 will be tightened to prevent the driven gear 22 from being out of meshing with the driving gear 23.

[0036] like Figures 1 to 3 As shown, in the two sliding grooves on the connecting bin 1, a gripping plate 27 is slidably connected to the sliding groove on the side away from the driving motor 28, and the gripping plate 27 is fixedly connected to the rotating rod 26. A fixing block is provided on the gripping plate 27, and the fixing block on the gripping plate 27 is fixedly connected to the driven gear 22 and contacts with the rotating rod 26. A snap-in groove is provided on the gripping plate 27, and a snap-in block is provided on the driven gear 22. By providing the gripping plate 27, the gripping plate 27 can be fixedly connected to the driven gear 22 through the fixing block. When in use, the gripping plate 27 is pulled to make the rotating rod 26 slide out of the sliding groove on the connecting bin 1, so that the rotating rod 26 can be removed. By providing the snap-in groove and the snap-in block, the rotating rod 26 can be rotated when the gear rotates, and the gripping plate 27 can prevent the rotating rod 26 from slipping off the driven gear 22.

[0037] The above solution also has the problem that if the resistance sensor 3 is damaged, it will directly affect the detection of the coil diameter. Figure 3As shown, a connecting plate 31 is fixedly connected to the top of the inner wall of the connecting bin 1, and a resistance sensor 3 is fixedly connected to the bottom of the connecting plate 31. Three resistance sensors 3 are provided, and sliding blocks are slidably connected to the three resistance sensors 3. The sliding blocks on the resistance sensors 3 are fixedly connected to the rotating rod 26. By providing the sliding blocks on the resistance sensors 3, when the roll film on the rotating rod 26 gradually rolls thicker, the sliding blocks on the resistance sensors 3 will be driven to move, thereby realizing the detection of the roll diameter;

[0038] like Figure 3 , Figure 5 As shown, the three resistance sensors 3 are all fixedly connected with connecting wires 32. By providing the connecting wires 32 to connect the three resistance sensors 3, the resistance sensors 3 can be connected in series, so that the resistance sensors 3 can be conveniently connected to the display screen when in use. Even if one resistance sensor 3 is damaged, the remaining resistance sensors 3 will also supplement the missing values ​​on average, so as to avoid the problem that the individual resistance sensors 3 are damaged, resulting in too large deviation in the measured value of the coil diameter.

[0039] The above solution also has the problem that the film may be loose when rolled onto the rotating rod 26, which may affect the test results. Figures 1 to 5 As shown, the bottom of the rotating rod 26 is rotatably connected to the bottom tray 24, and the bottom tray 24 is fixedly connected to a connecting rod 25. Both ends of the connecting rod 25 are slidably connected to the driven gear 22. The connecting bin 1 is rotatably connected to a tensioning roller 4, and the connecting bin 1 is slidably connected to a sliding roller 41. The tensioning roller 4 and the sliding roller 41 are provided to fix and tighten the rolled film, so as to avoid it being too loose when rolled onto the rotating rod 26, which affects the detection result.

[0040] Working principle:

[0041] like Figure 1-5 As shown: a transmission assembly 2 is provided, including a tooth block 21, a driven gear 22, a rotating rod 26, a driving gear 23, etc. The tooth block 21 is fixed in the sliding groove of the connecting warehouse 1 and meshes with the driven gear 22. The driven gear 22 is clamped on the rotating rod 26. The rotating rod 26 is in transmission connection with another driven gear 22, and the driven gear 22 is in transmission connection with the driving gear 23. One of the driving gears 23 is fixedly connected to the driving motor 28, and the driving motor 28 is slidably connected to the inner wall of the connecting warehouse 1 through a bracket. When the driving motor 28 is working, it can drive the driving gear 23 to rotate, and then drive the driven gear 22 to roll on the tooth block 21, so that the rotating rod 26 rises, tightens the transmission rope 29, and maintains the meshing state between the gears, thereby realizing the lifting of the rotating rod 26. The motor has high controllability, realizes automatic winding diameter detection, reduces manual intervention, improves detection efficiency, and avoids the problem of using a cylinder for lifting, and it is not easy to stop and maintain stability at any position in the stroke.
