Description

Technical Field

[0001] The utility model relates to a processing device for filling and ramming drugs into the paper tubes of pearl-bursting fireworks. Background Art

[0002] In the prior art, the Chinese patent document with the authorization announcement number CN 208872181 discloses a "variable-stroke drug filling and ramming device for pearl-bursting fireworks". Since 2017, we have participated in the research and development of this drug filling and ramming device, and on November 22, 2022, it was assigned to Liling Changliang Machinery Factory, an affiliated enterprise of the applicant of this application. On this basis, combined with the practical experience in recent years, we have further upgraded and transformed this drug filling and ramming device, and obtained the technical achievements described in this application. The full text of this application quotes this patent document.

[0003] The main problem existing in the existing drug filling and ramming device is that the existing device detects whether the cage reaches the end of the descending stroke (i.e., touches the bottom) by monitoring the slack of the cable pulling the traction cage, but the stability of this bottom-touching detection is poor, and it is difficult to ensure that the pressing force of drug ramming is appropriate. Summary of the Utility Model

[0004] In order to solve the above drawbacks, the technical problem to be solved by the utility model is to provide a filling and ramming device for pearl-bursting fireworks drugs, which effectively improves the stability of the bottom-touching detection of the cage. To solve the above technical problem, the technical solution adopted by the utility model is a filling and ramming device for pearl-bursting fireworks drugs, including a cage, and the cage includes a plurality of parallel and juxtaposed cage rods; a plurality of upper and lower parallel distributed limiting guide plates are movably sleeved on each cage rod and the lifting guide column, and each limiting guide plate is connected by a flexible connecting piece; it is characterized in that the cage is provided with a synchronous belt driving mechanism: the cage is installed on a lifting slider, and the lifting slider is installed on the lifting guide column; a synchronous belt fixing piece is arranged on the lifting slider, and the synchronous belt is driven by a servo motor to run forward / backward to drive the whole cage to lift; the synchronous belt driving mechanism further includes a torque detection and control component of the servo motor: when the cage touches the bottom, the resistance torque increases, resulting in an increase in the working current of the servo motor, and this component monitors the increase in the working current and sends a signal to control the servo motor to reverse and drive the cage to rise.

[0005] The beneficial effect of the utility model is that through the accurate stroke control of the synchronous belt and the accurate monitoring of the servo motor electrical signal, the stability and reliability of the bottom-touching detection of the cage are effectively improved, so as to ensure that the pressing force of drug ramming is appropriate; at the same time, the problem of complicated subsequent lubrication and maintenance work caused by using a steel cable or a chain as a cable is avoided.

[0006] In practice, we found that the jamming of the lottery sticks in the lottery cage is the main cause of the deflagration accident of the device. In one embodiment, the filling and ramming device is provided with a jamming detection component, which includes a liftable touch plate arranged on the lifting slider. The tops of the lottery sticks are installed on the lifting slider through elastic sleeves, and when the top ends of the lottery sticks extend out of the elastic sleeves, they abut against the lower surface of the liftable touch plate. A monitoring sensor is correspondingly arranged on the side surface of the liftable touch plate, such as a photoelectric switch sensor. As long as any lottery stick in the lottery cage jams, it will push up the liftable touch plate, and the monitoring sensor detects the rise of the liftable touch plate and sends an alarm signal to control the system to stop automatically.

[0007] In one embodiment, the synchronous belt is installed on the synchronous pulley set, and the servo motor drives the synchronous pulley set. One side of the synchronous belt of the synchronous pulley set is fixedly connected to the lifting slider, and the other side of the synchronous belt of the synchronous pulley set is fixedly connected to the counterweight slider. On the one hand, it can reduce the load of the traction synchronous motor, and on the other hand, it can weaken the impact vibration brought by the excessive mass on one side of the lottery cage to the operation.

[0008] In one embodiment, a positioning card plate for the paper tube cluster is correspondingly arranged on one side below the lottery cage. The positioning card plate is provided with a frame corresponding to the outer contour shape of the paper tube cluster, and the paper tube cluster is pushed into the frame to achieve rapid positioning; the positioning card plate is provided with a height adjustment component to adaptively adjust the height of the positioning card plate according to the specifications of the paper tube cluster.

[0009] In one embodiment, the drug filling and ramming device is provided with a locking component for the paper tube positioning plate, which includes locking hooks corresponding to the card slots on both sides of the paper tube positioning plate. The locking hooks are connected to a driving member for telescopic movement to achieve rapid locking and positioning of the paper tube positioning plate.

[0010] In one embodiment, the filling and ramming device is provided with an explosion-proof isolation cabinet. The explosion-proof isolation cabinet is provided with a feeding operation window, and the feeding operation window is provided with an automatic opening and closing door. An axial flow fan is arranged outside the explosion-proof isolation cabinet. The general process sequence during an accident is as follows: ① The paper tube cluster catches fire, ② The flash beads are ejected, ③ The stored drugs are ignited, leading to the expansion of the accident. By restricting the ejected flash beads within the cabinet through the explosion-proof isolation cabinet, the stored drugs will not be ignited, preventing the expansion of the accident. The lifting slider, the counterweight slider, the drug ramming lottery cage, the paper tube cluster and its paper tube positioning plate, etc. are all installed in the explosion-proof isolation cabinet to ensure the prevention of possible flame overflow during an accident. When the device operates, it is necessary to frequently fill materials into the paper tube cluster and then use the lottery stick to tamp the drug; in order to facilitate feeding and prevent personal injury caused by deflagration accidents during tamping, it is very necessary to set an automatic opening and closing feeding operation window. When the device starts to operate, the axial flow fan runs to timely extract the dust generated during the operation, further reducing the risk of accidents.

[0011] In one embodiment, the filling and tamping device is provided with a flame sensor and an automatic sprinkler assembly. The automatic sprinkler assembly includes a gas-pressurized water tank, a sprinkler pipeline, and a sprinkler head. Once a fire breaks out in the paper tube cluster during operation and is promptly detected by the flame sensor, a sprinkling instruction is issued: the sprinkler solenoid valve is opened, and the stored water in the pressurized water tank is sprayed out through the sprinkler head to extinguish the fire in a timely manner.

Detailed implementation manners

[0032] Refer to the appendix Figure 1-11 , which reflects a specific structure of the present utility model. The filling, ramming and pressing device for the pearl - shooting type fireworks medicine includes a signing cage 110, and the signing cage 110 includes a plurality of signing rods 114 arranged in parallel side by side; a plurality of limit guide plates 115 distributed vertically in parallel are movably sleeved on each signing rod 114 and two lifting guide posts 116, and the limit guide plates 115 are connected by flexible connecting pieces 117.

[0033] The signing cage 110 is provided with a synchronous belt drive mechanism:

[0034] The lottery cage 110 is installed on the lifting slider 103, and the lifting slider 103 is installed on the lifting guide post 116; a fixing member 121 of the synchronous belt 120 is provided on the lifting slider 103, and the synchronous belt 120 is driven by the servo motor 113 to run forward / backward to drive the overall lifting movement of the lottery cage 110; the synchronous belt drive mechanism further includes a torque detection and control component of the servo motor: when the lottery cage 110 touches the bottom, the resistance torque increases, resulting in an increase in the working current of the servo motor 113. This component monitors the increase in the working current and sends a signal, and the control system controls the servo motor 113 to reverse and drive the lottery cage 110 to rise. Through the accurate stroke control of the synchronous belt 120 and the accurate monitoring of the electrical signal of the servo motor 113, the stability and reliability of the bottom touch detection of the lottery cage 110 are effectively improved, thereby ensuring that the pressing force of the drug pressing is appropriate; at the same time, the problem of complicated subsequent lubrication and maintenance work caused by using a steel cable or a chain as a cable is avoided.

[0035] In the example, the filling and pressing device is provided with a jamming detection component, which includes a liftable touch plate 103a provided on the lifting slider 103. The tops of the lottery rods 114 are installed on the lifting slider 103 through elastic sliding sleeves. The elastic sliding sleeve includes a sliding sleeve 118 fixed on the lifting slider 103. A compression spring 119 is provided in the sliding sleeve 118. The top of the lottery rod 114 passes through the sliding sleeve 118 and the compression spring 119, and the lower end of the compression spring 119 acts on the outer peripheral step 114a of the lottery rod 114. As long as any one of the lottery rods 114 in the lottery cage is jammed, the top of the lottery rod 114 extends out of the sliding sleeve 118, abuts against the lower surface of the liftable touch plate 103a and pushes it up. A monitoring sensor - a photoelectric switch sensor 103b is correspondingly provided on the side surface of the liftable touch plate 103a. When the monitoring sensor detects that the liftable touch plate 103a rises, it sends an alarm signal and the control system automatically shuts down.

[0036] In the example, two synchronous belts 120 are respectively installed on two synchronous pulley groups composed of a driving synchronous pulley 102 and a tensioning synchronous pulley 104 to balance the overall lifting movement of the lottery cage 110 driven by traction. The servo motor 113 drives the synchronous pulley group through the driving synchronous pulley 102. One side of the synchronous belt 120 of the synchronous pulley group is fixedly connected to the lifting slider 103, and the synchronous belt 120 on the other side of the synchronous pulley group is fixedly connected to the counterweight slider 105. When the lifting slider 103 rises / falls, the counterweight slider 105 rises / falls accordingly. On the one hand, it can reduce the load of the servo motor 113, and on the other hand, it can weaken the impact vibration brought by the too large mass on one side of the lottery cage 110 during operation.

[0037] In the example, a positioning card board 108 for the paper tube cluster 111 is correspondingly arranged on one side below the signing cage 110. The positioning card board 108 is provided with a frame corresponding to the outer contour shape of the paper tube cluster 111. The paper tube cluster 111 can be quickly positioned by being pushed into the frame. The positioning card board 108 is provided with a height adjustment component to adaptively adjust the installation height of the positioning card board 108 on the installation column 108a according to the specifications of the paper tube cluster.

[0038] In the prior art, as shown in the Chinese patent document with the authorization announcement number CN 208872181, it uses a locking elastic band 32 to fix the relative positions of the paper tube positioning board and the paper tube cluster. The locking is not reliable and the operation is inconvenient. Therefore, in the example, the drug filling and ramming device is provided with a locking component for the paper tube positioning board 112. This component includes locking hooks 106 corresponding to the card slots 112a on both sides of the paper tube positioning board 112. The locking hooks 106 are connected to a locking cylinder 122 to perform up and down telescopic movements. When retracting, the locking hooks 106 hang and press on the card slots 112a to achieve quick locking and positioning of the paper tube positioning board 112.

[0039] In the example, the filling and ramming device is provided with an explosion-proof isolation cabinet. The lifting slider, the counterweight slider, the medicine ramming signing cage, the paper tube cluster and its paper tube positioning board, etc. are all installed in the explosion-proof isolation cabinet to ensure that the possible flame overflow during an accident can be prevented. By restricting the ejected bright beads within the cabinet through the explosion-proof isolation cabinet, the stored drugs will not be ignited, preventing the expansion of the accident.

[0040] The front door 107 of the isolation cabinet of the explosion-proof isolation cabinet is provided with a feeding operation window, and the feeding operation window is provided with an automatically opening and closing door 107a driven by a cylinder. During the operation of this device, it is necessary to frequently load materials into the paper tube cluster, and then use a signing rod to punch and ram the medicine. To facilitate feeding and prevent personal injury caused by deflagration accidents during punching, it is very necessary to set an automatically opening and closing feeding operation window.

[0041] An axial flow fan (not shown in the figure) is arranged outside the explosion-proof isolation cabinet. When the device starts to operate, the axial flow fan runs to timely extract the dust generated during the operation, further reducing the risk of accidents.

[0042] In the example, a flame sensor 109 and an automatic sprinkler component are correspondingly arranged at the upper end of the paper tube cluster 111 in the filling and ramming device. The automatic sprinkler component includes a gas pressurized water tank 201, a sprinkler pipeline 207 and a sprinkler head 208 inside the explosion-proof isolation cabinet. Once a fire occurs in the paper tube cluster during the operation and is timely detected by the flame sensor, a sprinkler instruction is issued: the sprinkler electromagnetic valve is opened, and the stored water in the pressurized water tank is sprayed out through the lotus-shaped sprinkler head 208 to timely extinguish the fire.
