Description

Technical Field

[0001] The utility model belongs to the technical field of cigarette-making equipment, and particularly relates to a transmitter synchronous signal acquisition device. Background Art

[0002] The YF24B-1IA filter rod transmitter is the main model that provides automatic supply of filter rods to high-speed cigarette-making machines. It uses unitary feeding and transmission. Every two units can supply the filter rods required for production to one receiver, that is, one cigarette-making machine. If there are 15 cigarette-making machines, at least 30 units of transmitters are required to meet the normal production of these cigarette-making machines. The internal structure of each unit of the filter rod transmitter is complex and chaotic, especially the back transmission part is even narrower. In a space with a width of less than 16 cm, there are a main drive motor, a tension pulley, a drum transmission pulley, a bin transmission pulley, a rear main body structure assembly, a mounting bracket for a signal acquisition rotary encoder, and a pneumatic pipeline, as well as a double-sided toothed belt running through the upper and lower parts.

[0003] The mounting bracket of the signal acquisition rotary encoder is at the bottom of all transmission mechanisms, inside the rear main body structure assembly, and within the loop of the double-sided toothed belt. It is connected to the transmission pulley of the gun by a coupling to detect the synchronous state when each unit emits filter rods. During operation, the connecting wire of the signal acquisition rotary encoder is intertwined with the double-sided toothed belt. If one of them is damaged and needs to be replaced, the other one must also be disassembled. Since the double-sided toothed belt runs in a narrow space and corresponds to many transmissions, the wrap angle of the pulley is increased. Coupled with the polygon effect of the small pulley, the toothed belt is equivalent to running in a state of endless folding, and the internal steel wire is easily broken and damaged. The service life is mostly about three months and needs to be replaced. Due to the limited space and blocked vision during the installation of the coupling of the signal acquisition rotary encoder or other technical conditions, it is very difficult to make the transmission axis of the coupling concentric with that of the gun. Under such working conditions, the average service life is also about three months. Particularly cumbersome is that the signal acquisition rotary encoder and the double-sided toothed belt are hooked together at the bottom of the transmission structure and need to be disassembled and installed simultaneously, resulting in a relatively high disassembly and installation frequency for both of them.

[0004] The mounting bracket of the signal acquisition rotary encoder is fastened to the central part of the unit frame. At a depth height of 32 cm and a transverse depth length of 34.5 cm, the width of the wall panels on both sides of the frame is less than 16 cm. This causes great obstacles for maintenance workers during repair and disassembly. When seeing the component, they can't reach it; when reaching it, they can't see it. It's difficult to operate with two hands and impossible to operate with one hand, resulting in inconvenient maintenance. Moreover, the right angles formed by all the machined surfaces on the unit frame are not treated with rounded or obtuse angles, which can easily cut the arm. If one wants to operate in a standardized manner and replace any one of the parts such as the double-sided toothed belt, coupling, or signal acquisition rotary encoder in a safe state, it is necessary to successively disassemble the emission pipeline, main drive motor, rear main structure assembly, and the mounting bracket of the signal acquisition rotary encoder, etc. One replacement cycle takes at least sixty or seventy minutes, resulting in low efficiency of maintenance operations. When the disassembly and assembly frequency is high, it takes even longer, greatly affecting the production efficiency. Therefore, how to make the disassembly and assembly of the rotary encoder more convenient and improve the efficiency of the rotary encoder maintenance operation has become a technical problem that needs to be urgently solved by those skilled in the art. Summary of the Utility Model

[0005] The purpose of the present utility model is to provide a transmitter synchronous signal acquisition device to solve the above-mentioned technical problems in the prior art.

[0006] To achieve the above purpose, the present utility model provides the following technical solutions:

[0007] A transmitter synchronous signal acquisition device includes a fixing bracket, a rotary encoder, a toothed belt pulley, an adjusting bolt, an adjusting bracket, and an elastic member. The fixing bracket is an inverted L-shaped bracket. The horizontal plate of the fixing bracket is used to connect with the wall panel above the double-sided toothed belt. A chute is vertically arranged on the front side of the vertical plate of the fixing bracket. The adjusting bracket includes a vertically arranged sliding plate and an adjusting plate. The sliding plate is slidably arranged in the chute. The adjusting plate is perpendicularly connected to the rear side of the upper end of the sliding plate and is located directly above the horizontal plate. A through hole for the screw rod of the adjusting bolt to pass through is arranged on the adjusting plate. A threaded hole for cooperating with the screw rod is arranged on the horizontal plate. The through hole and the threaded hole are arranged opposite to each other. The elastic member is arranged between the bolt head of the adjusting bolt and the adjusting plate. The rotary encoder is connected to the lower part of the front side of the sliding plate. The toothed belt pulley is coaxially connected to the front end of the rotary encoder. The toothed belt pulley is used to mesh with the outer ring of the double-sided toothed belt.

[0008] Preferably, the horizontal plate is detachably connected to the wall panel.

[0009] Preferably, two mounting holes for connecting with the wall panel are oppositely arranged on the horizontal plate, and the two mounting holes are respectively located on both sides of the through hole.

[0010] Preferably, the toothed belt pulley is a bakelite toothed belt pulley.

[0011] Preferably, the elastic member is a spring.

[0012] Preferably, the sliding groove is a dovetail groove.

[0013] The beneficial effects of the present utility model are as follows:

[0014] For the transmitter synchronization signal acquisition device of the present utility model, its rotary encoder is arranged on the wall panel above the double-sided toothed belt through a fixing bracket, and the toothed belt pulley used for being coaxially connected with the rotary encoder meshes with the outer ring of the double-sided toothed belt, so that the rotary encoder is located above each transmission component, effectively avoiding the shaft and connecting wires of the rotary encoder from being hooked with other transmission components. In this way, when repairing the rotary encoder, only need to screw out the adjusting bolt from the screw hole, then the adjusting bracket can be taken out from the fixing bracket, and only need to screw the adjusting bolt into the screw hole, then the adjusting bracket can be installed on the fixing bracket, which is convenient for realizing the disassembly and assembly of the rotary encoder without disassembling and assembling other transmission components, thus making the disassembly and assembly of the rotary encoder relatively convenient and effectively improving the efficiency of maintenance operations. At the same time, during use, by rotating the adjusting bolt, the bolt head of the adjusting bolt pushes the sliding plate to move downward along the sliding groove through the elastic member until the toothed belt pulley reliably meshes with the double-sided toothed belt, thereby ensuring that the information collected by the rotary encoder is relatively accurate.

[0025] In order to enable those skilled in the art to better understand the technical solution of the present utility model, the following will further introduce the solution in detail in combination with specific embodiments.

[0026] As Figures 1 to 4 shown, the embodiment of the present utility model provides a transmitter synchronization signal acquisition device 71, which includes a fixed frame 11, a rotary encoder 51, a toothed belt pulley 52, an adjusting bolt 31, an adjusting frame 21, and an elastic member. The fixed frame 11 is an inverted L-shaped frame. The horizontal plate 13 of the fixed frame is used to connect with the wall plate above the double-sided toothed belt 61. A chute 14 is vertically arranged on the front side of the vertical plate 12 of the fixed frame; the adjusting frame 21 includes a vertically arranged slide plate 22 and an adjusting plate 23. The slide plate 22 is slidably arranged in the chute 14. The adjusting plate 23 is perpendicularly connected to the rear side of the upper end of the slide plate 22 and is located directly above the horizontal plate 13; a through hole for the screw rod of the adjusting bolt 31 to pass through is arranged on the adjusting plate. A threaded hole 15 for cooperating with the screw rod is arranged on the horizontal plate 13. The through hole and the threaded hole 15 are arranged opposite to each other. The elastic member is arranged between the bolt head of the adjusting bolt 31 and the adjusting plate 23; the rotary encoder 51 is connected to the lower part of the front side of the slide plate 22, and the toothed belt pulley 52 is coaxially connected to the front end of the rotary encoder 51. The toothed belt pulley 52 is used to mesh with the outer ring of the double-sided toothed belt 61.

[0027] The transmitter synchronization signal acquisition device 71 provided by the embodiment of the utility model has a rotary encoder 51 which is arranged on the wall panel above the double-sided toothed belt through a fixing frame 11, and a toothed belt wheel 52 which is coaxially connected to the rotary encoder is meshed with the outer ring of the double-sided toothed belt, so that the rotary encoder 51 is located above each transmission component, effectively avoiding the axis and connecting lead of the rotary encoder 51 from being hooked with other transmission components. In this way, when repairing the rotary encoder, only the rotary encoder needs to be disassembled and assembled without disassembling other transmission components, thereby making the disassembly and assembly of the rotary encoder more convenient and effectively improving the efficiency of the maintenance work. At the same time, when in use, by rotating the adjustment bolt, the bolt head of the adjustment bolt 31 is used to push the slide plate 22 downward along the slide groove 14 through the elastic member until the toothed belt wheel is reliably meshed with the double-sided toothed belt, thereby ensuring that the information collected by the rotary encoder is more accurate.

[0028] Furthermore, the transverse plate 13 is detachably connected to the wall plate, so that the fixing frame can be easily replaced or repaired.

[0029] Specifically, the horizontal plate 13 is provided with two mounting holes 16 for connecting with the wall plate, and the two mounting holes 16 are respectively located on both sides of the through hole 15. With this solution, two fastening bolts are respectively passed through the two mounting holes and matched with the corresponding threaded holes on the wall plate, and then fastened, so that the horizontal plate can be firmly fixed on the wall plate. It can be understood that the wall plate is provided with two mounting holes with threaded holes corresponding to each other.

[0030] Furthermore, the toothed belt wheel 52 is a bakelite toothed belt wheel, so that the toothed belt wheel is lighter in weight.

[0031] Preferably, the elastic member is a spring 41. It is understandable that the spring is sleeved on the screw rod, the upper end of the spring 41 abuts against the bolt head, and the lower end of the spring 41 abuts against the top surface of the adjustment plate. In order to prevent the double-sided toothed belt from jumping due to the looseness and tension of the double-sided toothed belt, which may cause the toothed belt wheel to jump teeth and cause the rotary encoder to be misaligned, the elastic member is arranged between the bolt head and the adjustment plate as a damping balance device, so that the toothed belt wheel and the double-sided toothed belt can always maintain a good meshing gap, ensuring the effective operation of the toothed belt wheel and the rotary encoder.

[0032] Specifically, the slide groove 14 is a dovetail groove, so that the slide plate can be better guided to slide up and down in the slide groove. It can be understood that at this time, the left and right sides of the slide plate 22 have limiting inclined surfaces 24 that block and connect with the left and right inclined sides of the dovetail groove.

[0033] Preferably, the rotary encoder 51 can be fixed on the slide plate by a flange, and its connecting wire can also be fixed on the slide plate; the number of teeth of the toothed belt pulley can be the same as that of the toothed belt pulley of the cigarette jettisoning gun in the prior art; the toothed belt pulley is installed on the shaft at the front end of the rotary encoder, and the shaft of the rotary encoder is perpendicular to the slide plate; when the double-sided toothed belt runs, it drives the toothed belt pulley to rotate, and the toothed belt pulley drives the shaft of the rotary encoder to rotate, and the rotary encoder can perform information acquisition work.

[0034] The transmitter synchronization signal acquisition device 71 of the present invention eliminates the mutual entanglement between the rotary encoder and its connecting wire and the double-sided toothed belt without changing the original transmission mechanism of the filter rod transmitter, simplifies the replacement process of the rotary encoder, effectively reduces the replacement time, can reduce the replacement time of the rotary encoder from the original six or seven minutes to six or seven minutes, significantly reduces the labor intensity of the maintenance workers, and improves the maintenance efficiency.

[0035] The above is only the preferred embodiment of the present invention. It should be noted that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. Moreover, after reading the content of the present invention, those skilled in the relevant art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.
