Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

As shown in fig. 1-5, the utility model provides a pair of vice hard waste conveyer belt protection device of cigarette making and plug assembling unit back, including cigarette making and plug assembling unit back is vice hard waste conveyer belt 1, and the vice hard waste conveyer belt of cigarette making and plug assembling unit back 1 one side fixedly connected with backup pad 11, the slope of backup pad 11 sets up, and backup pad 11 one side has door plant 111 through hinge, and door plant 111 can shelter from personnel, thereby prevents that personnel's accident from touching cigarette making and plug assembling unit back is vice hard waste conveyer belt 1 and leads to dangerous emergence. One side of the door plate 111 is fixedly connected with a switch plate 12, the other side of the door plate 111 is provided with a travel switch 13, the travel switch 13 is arranged corresponding to the switch plate 12, the travel switch 13 is connected with a normally open contact, the other side of the auxiliary return wire conveyer belt 1 of the cigarette making machine is provided with a conveyer belt driving motor 14, a delay time relay is arranged in the conveyer belt driving motor 14, and the model of the delay time relay is JSS 48A-S. The time delay relay conveying belt driving motor 14 is a servo motor with a contactor, and the model of the contactor is 3TF 4022-1X. The user can conveniently control the motor load and the motor rotating speed, and the time period is set through the time delay relay, so that the conveying belt driving motor 14 generates cyclic periodic stop and operation through the time delay relay. When the circuit is connected, the connector of the travel switch 13 is connected to the delay time relay coil pin 2 in series, a DC24V direct-current power supply is provided, and a 0V direct-current power supply is introduced to the delay time relay coil pin 7, so that when the door panel 111 is in an open state, the contact rod of the travel switch 13 is touched by the switch board 12, and the voltage of the delay time relay coil is in a power-off state. After DC24V DC voltage is connected to the pin 1 of the delay time relay, the self circulation function of the delay time relay is utilized to close the output end pin 4 through time delay and output the voltage to the pin A1 of the contactor coil, and simultaneously 0V voltage is connected to the pin A2 of the contactor, and the circulation control contactor of the delay time relay is realized, thereby controlling the operation interval of the conveyer belt driving motor 14, so that the conveyer belt driving motor 14 drives the auxiliary wire returning conveyer belt 1 of the back of the cigarette making and plug making machine to perform intermittent periodic operation, thereby effectively prolonging the service life and maintenance period of the conveyer belt, and saving the cost. When a user pulls the door plate 111 to one side to enable the door plate 111 to rotate by taking the hinge as a reference, the switch plate 12 which is in contact with the contact rod of the travel switch 13 rotates by taking the hinge as the reference along with the door plate 111, so that the lower end of the switch plate 12 is separated from the contact rod which forms the switch 13, and the contact rod of the travel switch 13 is reset, because the travel switch 13 is connected with a normally open contact, after the contact rod of the travel switch 13 is reset, the conveyer belt driving motor 14 stops running, the auxiliary return wire conveyer belt 1 of the back of the cigarette making machine stops running, the back of the cigarette making machine is convenient for a worker to maintain and process the back of the cigarette making machine, and the appliance is prevented from entering the inside of the back of the cigarette making machine to cause equipment damage and unnecessary maintenance working conditions. After the maintenance is finished, the maintenance personnel reversely rotate the door panel 111, the door panel 111 is stressed and reversely rotates by taking the hinge as a reference, the lower side of the door panel 111 is gradually close to and touches the upper side of the supporting plate 11, the door panel 111 is prevented from further rotating, because the supporting plate 11 is obliquely arranged, the lower side of the door panel 111 is in close contact with the upper side of the supporting plate 11 due to the self gravity of the door panel 111, the door panel 111 is prevented from moving and losing the protection effect, when the door panel 111 reversely rotates by taking the hinge as the reference and returns to the initial position, the switch board 12 arranged on one side of the door panel 111 follows the door panel 111 and reversely rotates by taking the hinge as the reference and generates thrust to the contact rod forming the switch 13, the contact rod of the travel switch 13 rotates, the conveying belt driving motor 14 operates again, and the auxiliary wire returning conveying belt 1 of the rear body of the cigarette making machine set operate again.

The time delay relay stopping time period is 120S, the operation time period is 30S, the time delay relay stopping time period is 120S, and the operation time period is 30S, so that the cigarette making machine back auxiliary cut tobacco conveying belt 1 can accumulate a proper amount of cut tobacco and convey the cut tobacco, and the electric energy is saved to the maximum degree while the conveying efficiency is maximized. Two baffles 2 of the 1 upside fixedly connected with of the auxiliary hard waste conveyer belt of cigarette making and tipping machine back prevent the tobacco shred from breaking away from the auxiliary hard waste conveyer belt 1 of cigarette making and tipping machine back, and a loading plate 3 is fixedly connected between the two baffles 2 and is used for bearing the tobacco shred conveyed by the auxiliary hard waste conveyer belt 1 of cigarette making and tipping machine back. The door plate 111 is provided with an observation groove, one side of the door plate 111 is fixedly connected with an observation cover 4, the observation cover 4 is arranged corresponding to the observation groove, and a worker can observe the working state of the back auxiliary wire returning conveying belt 1 of the cigarette making machine through the observation cover 4 and the observation groove.

When the auxiliary wire returning conveying belt is used, the time period is set through the delay time relay, so that the conveying belt driving motor 14 generates cyclic periodic stop and operation through the delay time relay, the conveying belt driving motor 14 drives the auxiliary wire returning conveying belt 1 of the rear body of the cigarette making machine to perform intermittent periodic operation, the service life and the maintenance period of the conveying belt are effectively prolonged, and the cost is saved. The user is to one side pulling door plant 111, and the switch panel 12 that touches with travel switch 13 feeler lever follows door plant 111 and uses the hinge to rotate as the benchmark for the lower extreme of switch panel 12 breaks away from with the feeler lever that forms switch 13, and travel switch 13's feeler lever resets, and conveyer belt driving motor 14 stall, and the vice hard waste conveyer belt 1 of cigarette making machine back stops the function, makes things convenient for staff's maintenance and handles cigarette making machine back trouble. After the maintenance is finished, the maintenance personnel reversely rotate the door plate 111, the switch plate 12 arranged on one side of the door plate 111 reversely rotates along with the door plate 111 by taking the hinge as a reference and generates thrust to the feeler lever forming the switch 13, so that the feeler lever of the travel switch 13 rotates, the conveying belt driving motor 14 is rotated again, and the auxiliary wire returning conveying belt 1 of the rear body of the cigarette making machine starts to operate again.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
