Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bottle cap production equipment, in particular to a bottle cap knocking machine. BACKGROUND

[0002] In the field of liquor and beverage production, filling and packaging is a common packaging method, and after filling, the container bottle needs to be sealed with a bottle cap. As part of the filling and packaging, the bottle cap has two main functions: one is sealing, which protects the product in the container bottle, which is the most basic function of the bottle cap; the other is aesthetics, as an integral part of the filling and packaging, the bottle cap can play a crucial role. The bottle cap will go through several production processes during production, so it is inevitable that it will be contaminated with dust. In order to ensure the cleanliness of the product, the bottle cap needs to be dusted before being used to seal the container bottle. The traditional bottle cap dusting method is manual dusting, which has the problems of low efficiency and incomplete dusting.

[0003] Therefore, the applicant's prior application for a utility model patent (authorized publication number CN218835418U) discloses a bottle cap cleaning and dusting device, which comprises a feeding device, a cleaning device and a discharging device. The cleaning device has a turntable and a bottom plate arranged oppositely. The turntable is driven to rotate by a servo motor. The bottom plate has an upper surface with an annular array of feeding stations, inner air washing stations and discharging stations. The turntable has a plurality of bottle cap clamping devices, each of which corresponds to the next station. The feeding device has an outer air washing station connected to the feeding station. The discharging device is connected to the discharging station. The outer air washing station and the inner air washing station use air flow or gas flow to clean the outside and inside of the bottle cap by blowing compressed air or compressed gas.

[0004] The above-mentioned prior art can achieve automatic dusting of the bottle cap, but in actual use, the following problems still exist:

[0005] 1) The bottle cap is blown and dusted outside and inside at the outer air washing station and the inner air washing station, respectively. Therefore, in the overall dusting process of the bottle cap, two blowing and dusting operations are required, resulting in low overall dusting efficiency of the bottle cap;

[0006] 2) When the first air nozzle of the inner air washing station extends into the bottle cap to blow and dust it, the flying dust is likely to reattach to the inner wall of the bottle cap, or even overflow from the bottle cap and attach to the outer wall of the bottle cap, affecting the dusting effect;

[0007] 3) For dust that is attached firmly, only the blowing and dusting operation of the outer air washing station and the inner air washing station cannot completely remove the dust on the outside and inside of the bottle cap, thus it is difficult to achieve the desired dusting effect. SUMMARY

The inner diameter of the limiting hole is not less than the outer diameter of the bottle cap. The bottle cap passes through the limiting hole and contacts the soot knocking plate 524.

[0090] This embodiment also provides a bottle cap dust removal method, which is completed based on the above-described soot knocking machine and comprises the following steps.

[0091] S1, feeding and carrying: the feeding device delivers the bottle caps to be dusted into the cabinet 10 through the feeding opening 121. The carrying mechanism 30 drives the gripper mechanism 40 to move between the soot knocking mechanism 50 and the feeding device, and clamps the bottle caps on the feeding device to the soot knocking mechanism 50.

[0092] Specifically, the linear module 34 drives the carrying plate 33 to move along the carrying slide rail 32 towards the feeding opening 121, thereby driving the gripper mechanism 40 to move towards the feeding opening 121, until the gripper assembly 42 close to the feeding opening 121 is located above the discharge end of the feeding device.

[0093] The output shaft of the driving cylinder 4211 is elongated, so that the driving plate 4212 moves downward, thereby driving the jaw structure 422 to move downward until the two opposite clamping blocks 4227 are located on both sides of the bottle cap, at which time the bottle cap is in position corresponding to the clamping grooves on the clamping blocks 4227.

[0094] The output shaft of the left cylinder 4228 is elongated, driving the two left connecting plates 4224 to move rightward through the left synchronization plate 42210, thereby driving the clamping plates 4226 on the two left connecting plates 4224 and the clamping blocks 4227 on the clamping plates 4226 to move rightward. The output shaft of the right cylinder 4229 is synchronously elongated, driving the two right connecting plates 4225 to move leftward through the right synchronization plate 42211, thereby driving the clamping plates 4226 on the two right connecting plates 4225 and the clamping blocks 4227 on the clamping plates 4226 to move leftward. The two opposite clamping blocks 4227 move close to each other, clamping and fixing the bottle cap located therebetween.

[0095] The output shaft of the driving cylinder 4211 is shortened to reset, so that the driving plate 4212 moves upward to reset, thereby driving the jaw structure 422 to move upward to reset and taking the bottle cap away from the discharge end of the feeding device.

[0096] During the process of driving the jaw structure 422 to move up and down by the driving cylinder 4211 through the driving plate 4212, the guide rod 4213 slides up and down in the guide hole of the moving plate 41, guiding the up and down movement of the jaw structure 422 and ensuring that the jaw structure 422 moves along the preset trajectory.

[0097] The linear module 34 drives the carrying plate 33 to move along the carrying slide rail 32 toward the direction close to the discharge port 122, thereby driving the jaw assembly 42 to move toward the direction close to the discharge port 122, until the jaw assembly 42 close to the feeding port 121 and the bottle cap clamped thereby are located above the knocking mechanism 50.

[0098] S2, knocking: the jaw mechanism 40 drives the bottle cap to move up and down, so that the bottle cap collides with the knocking assembly 52 of the knocking mechanism 50, realizing the knocking operation of the bottle cap.

[0099] Specifically, the output shaft of the driving cylinder 4211 is elongated, so that the driving plate 4212 moves downward, thereby driving the jaw structure 422 and the bottle cap clamped thereby to move downward, so that the bottle cap collides with the knocking plate 524 at the corresponding position through the limiting hole of the limiting plate 56. The knocking plate 524 moves downward under the downward force of the bottle cap, so that the reset spring 526 is compressed. In this way, the elastic contact between the bottle cap and the knocking assembly 52 can be realized, avoiding damage to the bottle cap and the knocking assembly 52.

[0100] The dust attached to the bottle cap is loosened by the collision, and the dust on the outer part of the bottle cap falls onto the limiting plate 56, and the dust on the inner part of the bottle cap falls into the dust cover 551 through the hollow shaft 523.

[0101] The output shaft of the driving cylinder 4211 is retracted, so that the driving plate 4212 moves upward, thereby driving the jaw structure 422 and the bottle cap clamped thereby to move upward. At this time, the reset spring 526 is elongated, thereby driving the dust loosening plate 524 to move upward until the top of the dust loosening plate 524 abuts against the bottom of the limiting plate 56, so as to reset the dust loosening plate 524.

[0102] The above-mentioned actions are repeated, so that the bottle cap collides with the corresponding position of the dust loosening plate 524 for a preset number of times, that is, the dust loosening action of the bottle cap is completed.

[0103] After the last collision is completed, the clamping structure keeps clamping the bottle cap, so that the bottle cap stays on the dust loosening plate 524 for subsequent dust removal operation.

[0104] S3, dust removal: the external dust removal assembly 53 of the dust loosening mechanism 50 blows and removes the dust on the outer part of the bottle cap, and at the same time, the internal dust removal assembly 54 of the dust loosening mechanism 50 blows and removes the dust on the inner part of the bottle cap.

[0105] S3-1, external dust removal: the compressed gas of the external air source is delivered into the air knife 531 through the pipeline, and then is blown out through the air outlet of the air knife 531, so that the compressed gas blows and removes the dust remaining on the outer part of the bottle cap.

[0106] S3-2, internal dust removal: the compressed gas of the external air source is delivered into the dust blowing pipe 542 through the pipeline and the dust blowing joint 5422, and then is blown out through the dust blowing nozzle 5421, so that the compressed gas blows and removes the dust remaining in the inner part of the bottle cap.

[0107] The lifting structure 541 drives the dust blowing nozzle 5421 to move upward through the dust blowing pipe 542, so that the dust blowing nozzle 5421 extends into the bottle cap, thereby improving the dust blowing and removing effect in the inner part of the bottle cap. Specifically, the lifting motor 5411 drives the lifting screw 5412 to rotate, thereby driving the lifting plate 5413 to move upward through the lifting nut, so that the dust blowing pipe 542 connected to the lifting plate 5413 moves upward until the dust blowing nozzle 5421 connected to the top of the dust blowing pipe 542 extends into the bottle cap.

[0108] The rotating structure 543 drives the blowing ash nozzle 5421 to rotate along its own axis through the blowing ash pipe 542, improves the uniformity of the compressed gas blowing in the bottle cap, and further improves the blowing dust removal effect in the bottle cap. Specifically, the rotating motor 5431 drives the rotating driving wheel 5432 to rotate, thereby driving the rotating driven wheel 5433 to rotate through the rotating synchronous belt 5434, so that the blowing ash pipe 542 and the blowing ash nozzle 5421 rotate around their own axes.

[0109] S4, dust collection: during the process of simultaneously blowing and cleaning the outside and inside of the bottle cap by the external blowing ash assembly 53 and the internal blowing ash assembly 54, the dust collection assembly 55 synchronously performs dust collection treatment.

[0110] Specifically, the external high-pressure dust collector is started, and the dust collection pipe 552 generates negative pressure in the dust collection cover 551, so that the dust blown off by the blowing ash nozzle 5421 into the bottle cap and the hollow pipe is adsorbed into the dust collection cover 551, and finally collected into the high-pressure dust collector through the dust collection pipe 552.

[0111] After the dust removal operation is completed, the clamping jaw structure 422 releases the clamping of the bottle cap. That is, the output shaft of the left side cylinder 4228 is retracted and reset, and the two left connecting plates 4224 are driven to move left and reset through the left synchronous plate 42210, so that the clamping plate 4226 on the two left connecting plates 4224 and the clamping block 4227 on the clamping plate 4226 are moved left and reset. The output shaft of the right side cylinder 4229 is synchronously retracted and reset, and the two right connecting plates 4225 are driven to move right and reset through the right synchronous plate 42211, so that the clamping plate 4226 on the two right connecting plates 4225 and the clamping block 4227 on the clamping plate 4226 are moved right and reset. The two clamping blocks 4227 are reset away from each other, and the bottle cap located therebetween is released.

[0112] At this time, the bottle cap is placed on the top of the knocking ash plate 524 by the clamping jaw structure 422, and the bottle cap is located in the limiting hole of the limiting plate 56, so that the bottle cap can be limited to avoid tilting. The output shaft of the driving cylinder 4211 is retracted and reset, and the clamping jaw structure 422 is driven to move upward and reset.

[0113] S5, discharging and carrying: the carrying mechanism 30 drives the clamping jaw mechanism 40 to move between the knocking ash mechanism 50 and the connecting line 20, clamps the bottle cap on the knocking ash mechanism 50 to the connecting line 20, and the connecting line 20 transports the bottle cap after knocking ash and dust removal to the outside of the case 10 through the discharging port 122.

[0114] Specifically, the linear module 34 drives the carrying plate 33 to move along the carrying slide rail 32 towards the direction of the feeding port 121, so as to drive the jaw mechanism 40 to move towards the direction of the feeding port 121, until the jaw assembly 42 close to the feeding port 121 is located above the discharging end of the feeding device, so as to carry out the next feeding. At this time, the jaw assembly 42 close to the discharging port 122 is located above the knocking dust mechanism 50.

[0115] The output shafts of the driving cylinders 4211 of the two jaw assemblies 42 are synchronously elongated, so that the two driving plates 4212 are synchronously moved downwards, thereby driving the two jaw structures 422 to synchronously move downwards. Until the jaw assembly 42 close to the feeding port 121 has its two clamping blocks 4227 located on both sides of the bottle cap on the discharging end of the feeding device, and the jaw assembly 42 close to the discharging port 122 has its two clamping blocks 4227 located on both sides of the bottle cap on the knocking dust mechanism 50.

[0116] The left and right cylinders 4228 and 4229 of the jaw assembly 42 close to the feeding port 121 drive the two clamping blocks 4227 to approach each other in the manner of S1, so as to clamp and fix the bottle cap on the discharging end of the feeding device. The left and right cylinders 4228 and 4229 of the jaw assembly close to the discharging port 122 also drive the two clamping blocks 4227 to approach each other in the manner of S1, so as to clamp and fix the bottle cap on the knocking dust mechanism 50.

[0117] The output shafts of the driving cylinders 4211 of the two jaw assemblies 42 are synchronously shortened and reset, so that the two driving plates 4212 are synchronously moved upwards and reset, thereby driving the two jaw structures 422 to synchronously move upwards and reset, so as to take away the bottle cap to be knocked and dusted from the discharging end of the feeding device, and take away the bottle cap after the knocking and dusting operation from the knocking dust mechanism 50.

[0118] The linear module 34 drives the carrying plate 33 to move along the carrying slide rail 32 towards the direction of the discharging port 122, so as to drive the two jaw assemblies 42 to move towards the direction of the discharging port 122, until the jaw assembly 42 close to the feeding port 121 and the bottle cap clamped thereby are located above the knocking dust mechanism 50, and the jaw assembly 42 close to the discharging port 122 and the bottle cap clamped thereby are located above the feeding end of the connection line 20.

[0119] The output shafts of the two driving cylinders 4211 are synchronously elongated, so that the two driving plates 4212 are synchronously moved downward, thereby driving the two jaw assemblies 422 and the bottle caps clamped thereby to be synchronously moved downward. The jaw assembly 42 close to the feeding port 121 is collided with the corresponding knocking plate 524 through the limiting hole of the limiting plate 56, so as to realize the first knocking operation; and the bottle cap clamped by the jaw assembly 42 close to the discharging port 122 is buckled and placed on the limiting seat 24 of the corresponding position of the adapter plate 23. The jaw assembly close to the discharging port 122 releases the clamping of the bottle cap by the jaw assembly 422 in the manner of S4.

[0120] The adapter motor 25 drives the adapter driving wheel 26 to rotate, so as to drive the adapter plate 23 to move along the adapter slide rail 22 to the direction close to the discharging port 122 through the adapter synchronous belt 28, and the bottle cap after the knocking and dust removing operation is moved along with the adapter plate 23, and is conveyed to the outside of the cabinet 10 through the discharging port 122.
