Double-channel mosquito-repellent incense barrel cover pressing machine

Abstract

This utility model relates to the field of packaging machinery and discloses a double-channel mosquito coil barrel capping machine. It includes a conveyor table for transporting mosquito coil barrels, a suction mechanism, a capping mechanism, a conveyor table, a sliding plate, and a frame. In this utility model, under the rotation of the capping device, the rightmost fixed rod first caps the mosquito coil lid, locking one side of the lid into the upper edge of the mosquito coil barrel. The middle position of the lid is limited and supported to prevent it from sliding easily, ensuring the lid is accurately capped onto the barrel during capping. This prevents the lid from easily sliding off the barrel. Furthermore, when the lid is suctioned downwards by the negative pressure head, the elastic resistance of the inclined plate is adjusted by the threaded assembly, allowing the inclined plate to quickly rebound the moment the lid detaches. By adjusting the elastic force of the inclined plate and using a certain elastic friction to block subsequent lids on the side of the lid, the lid is easily blocked by the appropriate elastic friction of the inclined plate, preventing the problem of stacked lids easily detaching.

Description

Technical Field

[0001] This utility model relates to the field of packaging machinery, specifically a double-stage mosquito coil barrel capping machine. Background Technology

[0002] After the mosquito coils are filled, the double-layer mosquito coil bucket needs to be sealed with a lid. The double-layer sealing process ensures a tight seal between the lid and the bucket opening, avoiding insufficient sealing due to human error and preventing the mosquito coils from getting damp, scattering, or evaporating. The double-layer mosquito coil bucket sealing machine achieves high efficiency and standardization in the packaging of bucket mosquito coils through automated mechanical structure and intelligent control. Its core advantages lie in the enhanced sealing performance of the double-layer sealing process and the improved production efficiency due to full-process automation. However, when pressing the mosquito coil cap onto the mosquito coil bucket, if the cap is made of plastic, two pressing processes are required: initial pressing to align the position and increasing the pressing pressure to seal it. The plastic mosquito coil cap has a large sliding force, making it easy to detach from the top of the mosquito coil bucket during pressing. Furthermore, when the mosquito coil cap is being absorbed and detached, the stacked mosquito coil caps are difficult to separate. During absorption and detachment, after the bottom mosquito coil cap detaches, the mosquito coil caps stacked with it are easily pulled out and detached, affecting the subsequent sealing of the mosquito coil cap. Summary of the Invention

[0003] This invention provides a double-channel mosquito coil barrel capping machine, which overcomes the shortcomings described in the background art.

[0004] The technical solution adopted by this utility model to solve its technical problem is: A double-channel mosquito coil barrel capping and sealing machine includes a conveyor platform for transporting mosquito coil barrels, an adsorption mechanism, a sealing mechanism, a conveyor platform, a sliding plate, and a frame. Two conveyor platforms are fixed within the frame and parallel to each other. The adsorption mechanism is located inside the conveyor platforms. Three conveyor platforms are provided, with two platforms parallel to each other above the conveyor platforms and a third platform perpendicular to the two parallel platforms. A sliding plate is located on the side of the conveyor platforms and tilted to correspond to the sealing mechanism position. The sealing mechanism is located at the upper end of the conveyor platforms and presses the mosquito coil barrels transported to the sealing mechanism position. The adsorption mechanism includes a limiting structure, a negative pressure head, a telescopic device, an intercepting rod, a monitoring head, and a circular plate. The monitoring head is located on the upper end of the circular plate, and the circular plate is located on the upper end of the conveyor platform. Five evenly spaced intercepting rods are arranged in a ring on the inner side of the circular plate. The limiting structure is located at the lower end of the intercepting rods. The five intercepting rods are used to hold stacked mosquito coil covers. The limiting structure elastically blocks the bottom of the stacked mosquito coil covers. The lower end of the conveyor platform is equipped with a telescopic device. The upper end of the telescopic device is equipped with a negative pressure head on the central axis corresponding to the intercepting rod. The telescopic device drives the negative pressure head to move upward, causing the telescopic device to adsorb the mosquito coil cover in the middle of the intercepting rod and disengage it from the limiting structure.

[0005] A preferred technical solution: The limiting structure includes a spring, an inclined plate, a threaded assembly, and a support plate. Two springs are provided and are disposed between the inclined plate and the support plate. The threaded assembly passes through the support plate and the inclined plate and is fixed to the outside of the intercepting rod. The threaded assembly has a nut that rotates to push the support plate. The rotation of the nut causes the support plate to compress the spring, and the inclined plate moves open and close under the elasticity of the spring.

[0006] A preferred technical solution: The closing mechanism includes a monitor, a cover presser, a motor, and a transmission bar. Motors are located at both ends of the transmission bar, driving the transmission bar to transport the mosquito coil bucket via their outputs. The monitor contains two infrared sensors, one above the other. A blocking rod is located at the slide plate position. The blocking rod is opened and closed by two small motors located within the slide plate. A semi-circular groove is located above the monitor on the slide plate. The monitor senses the mosquito coil cover at the semi-circular groove position. When the downward-facing infrared sensor of the monitor detects that the mosquito coil bucket has been transported to the right from the transmission bar, an electrical signal controls the small motors to release the obstruction of the mosquito coil cover within the slide plate, causing the mosquito coil cover to tilt and fall onto the mosquito coil bucket. The motors are located on both sides of the upper end of the conveyor platform, driving the cover presser to rotate via their outputs. The cover presser rotates to the position of the fallen mosquito coil bucket, pressing the mosquito coil cover onto the upper end of the mosquito coil bucket.

[0007] A preferred technical solution: The cover presser is provided with a fixed rod, a connecting plate, a sponge layer, and a second rotating rod. The second rotating rod is located at the motor output end. The connecting plate is fixedly connected through the second rotating rod. There are three fixed rods, which are arranged horizontally. The fixed rod in the middle position is larger than the fixed rods on both sides. A sponge layer is attached to the outside of the fixed rod. The bottom of the sponge layer is located at the same horizontal position. After the motor rotates, under the elasticity of the sponge layer, the fixed rod in the middle position presses against the middle of the mosquito coil cover, and the fixed rods on both sides press the mosquito coil cover elastically through the sponge layer.

[0008] A preferred technical solution: The monitoring head and the telescopic device are electrically connected to each other. When the monitoring head cannot detect the mosquito coil cover inside the interception rod, the telescopic device stops driving the negative pressure head to work. The conveyor platform is equipped with a first rotating rod and a conveyor belt. There are two first rotating rods, one of which is rotated by a motor and drives the two conveyor belts to drive the transmission. The position between the two conveyor belts is hollow. The telescopic device drives the negative pressure head to move upward between the two conveyor belts.

[0009] A preferred technical solution: The adsorption mechanism is provided in two parts, which are arranged on a vertical conveyor and one of the parallel conveyor, and the two adsorption mechanisms are respectively located on the same side of the conveyor. The mosquito coil cover on the vertical conveyor is transferred to one of the parallel conveyor.

[0010] Compared with existing technologies, this technical solution has the following advantages: In this invention, the rotation of the nut on the threaded assembly causes the support plate to compress the springs, thus adjusting the elastic pressure of the springs on the inclined plate. When the mosquito coil cover is drawn downwards from the five ring-shaped intercepting rods by the negative pressure head, the mosquito coil cover presses against the inclined position of the inclined plate, causing the inclined plate to move outwards under the elasticity of the springs. This facilitates the passage of the mosquito coil cover through the inclined position of the inclined plate. By adjusting the elastic resistance of the springs on the inclined plate through the threaded assembly, the inclined plate can quickly rebound the moment the mosquito coil cover detaches. By adjusting the elastic force of the inclined plate, it can block the bottommost mosquito coil cover and block subsequent mosquito coil covers with a certain elastic friction on the side of the mosquito coil cover. Since subsequent mosquito coil covers have no adhesive force, they are easily blocked by the appropriate elastic friction of the inclined plate, preventing the mosquito coil covers from stacking and easily detaching.

[0011] In this invention, under the rotation of the cover presser, the rightmost fixing rod first presses down on the mosquito coil cover, locking one side of the mosquito coil cover into the upper edge of the mosquito coil bucket, and limiting one side of the mosquito coil cover. Since the thickness of the sponge layer in the middle position is the smallest, the pressing force of the middle fixing rod is the greatest. Under the cover pressure of the middle fixing rod and the sponge layer, the middle position of the mosquito coil cover is limited and supported, preventing the mosquito coil cover from easily sliding. After the connecting plate is rotated to a horizontal position by the second rotating rod, the fixing rods on both sides press the mosquito coil cover to the upper edge of the mosquito coil bucket under the elasticity of the sponge layer. Thus, by rotating the cover presser, the mosquito coil cover is accurately covered on the mosquito coil bucket when it is covered, preventing the mosquito coil cover from easily sliding off the mosquito coil bucket when it is closed.

Detailed Implementation

[0019] like Figures 1 to 5 As shown, this utility model proposes a double-channel mosquito coil barrel capping and sealing machine, including a conveyor platform 6 for transporting mosquito coil barrels, an adsorption mechanism 1, a sealing mechanism 2, a conveyor platform 3, a sliding plate 4, and a frame 5. There are two conveyor platforms 6, which are fixed inside the frame 5 and are parallel to each other. The adsorption mechanism 1 is located inside the conveyor platform 3. There are three conveyor platforms 3, two of which are arranged parallel to each other above the conveyor platform 6, and the other conveyor platform 3 is perpendicular to the two parallel conveyor platforms 3. The sliding plate 4 is located on the side of the conveyor platform 3 and is tilted to correspond to the position of the sealing mechanism 2. The sealing mechanism 2 is located at the upper end of the conveyor platform 6 and presses the mosquito coil barrels transported to the sealing mechanism 2. The adsorption mechanism 1 includes a limiting structure 11, a negative pressure head 12, a telescopic device 13, an intercepting rod 14, a monitoring head 15, and a circular plate 16. The monitoring head 15 is located on the upper end of the circular plate 16, which is located on the upper end of the conveyor platform 3. Five equally spaced intercepting rods 14 are arranged in a ring on the inner side of the circular plate 16. The limiting structure 11 is located at the lower end of the intercepting rods 14. The five intercepting rods 14 are used to place stacked mosquito coil covers. The limiting structure 11 elastically blocks the bottom of the stacked mosquito coil covers. The lower end of the conveyor platform 3 is provided with a telescopic device 13. The upper end of the telescopic device 13 is provided with a negative pressure head 12 on the central axis corresponding to the intercepting rods 14. The telescopic device 13 drives the negative pressure head 12 to move upward, and causes the telescopic device 13 to adsorb the mosquito coil cover in the middle of the intercepting rods 14 and disengage it from the limiting structure 11.

[0020] The limiting structure 11 includes a spring 111, an inclined plate 112, a threaded assembly 113, and a support plate 114. Two springs 111 are provided and are disposed between the inclined plate 112 and the support plate 114. The threaded assembly 113 passes through the support plate 114 and the inclined plate 112 and is fixed to the outside of the interceptor rod 14. The threaded assembly 113 has a nut that rotates to push the support plate 114. The rotation of the nut causes the support plate 114 to compress the spring 111, and the inclined plate 112 moves open and close under the elasticity of the spring 111.

[0021] Furthermore, the negative pressure head 12 generates negative pressure adsorption force through an external negative pressure device, so that when the negative pressure head 12 extends and retracts, it is located on the central axis of the intercepting rod 14 to adsorb the mosquito coil cover. Under the adsorption force, the mosquito coil cover is pushed downward to break away from the obstruction of the limiting structure 11. After breaking away from the obstruction, the mosquito coil cover is blocked and intercepted by the conveyor belt 302, so that the mosquito coil cover is transferred to the slide plate 4 on the conveyor belt 302.

[0022] Furthermore, when the slide plate 4 is tilted at 40° and the sealing mechanism 2 is not performing a sealing action, the conveyor belt 302 will not transfer the contents to the slide plate 4 again, thus preventing the mosquito coil cover from becoming too crowded at the position of the slide plate 4.

[0023] Furthermore, the monitor 21 consists of upper and lower infrared sensors. The lower infrared sensor detects the position of the mosquito coil bucket, while the upper infrared sensor monitors the mosquito coil cover.

[0024] In this invention, the mosquito coil bucket is transported from the conveyor 6 to the right-side closing mechanism 2, and the mosquito coil cover in the adsorption mechanism 1 is transported from the conveyor 3 to the slide plate 4. The mosquito coil cover slides intermittently from the slide plate 4 to the closing mechanism 2, causing the mosquito coil cover to fall onto the top of the mosquito coil bucket at the closing mechanism 2. At this time, the conveyor 6 is in a stopped transport state, and then the closing mechanism 2 covers the mosquito coil cover at the top of the mosquito coil bucket. After the covering is completed, the conveyor 6 transports the mosquito coil bucket again, and the slide plate 4 continues to drop the mosquito coil cover onto the mosquito coil bucket at the closing mechanism 2. This process is repeated to achieve the effect of covering the mosquito coil bucket.

[0025] In this invention, the two springs 111, through the rotation of the nut on the threaded assembly 113, cause the support plate 114 to compress the springs 111. This adjusts the elastic pressure of the springs 111 on the inclined plate 112. When the mosquito coil cap is drawn downwards from within the five annular intercepting rods 14 by the negative pressure head 12, the mosquito coil cap presses against the inclined position of the inclined plate 112, causing the inclined plate 112 to move outwards under the elasticity of the springs 111. This facilitates the passage of the mosquito coil cap through the inclined position of the inclined plate 112. By rotating the nut on the threaded assembly 113, the elastic resistance of the springs 111 on the inclined plate 112 is adjusted, allowing the inclined plate 112 to detach from the mosquito coil cap. It can rebound quickly and block subsequent mosquito coil covers, preventing them from easily detaching at the moment of detachment. This requires adjusting the elasticity of the limiting structure 11. The required adsorption force for the mosquito coil cover to detach is not too large, nor is the elasticity too small, which would cause subsequent mosquito coil covers to detach as the first one detaches. By adjusting the elasticity of the inclined plate 112, the inclined plate 112 blocks the bottommost mosquito coil cover and uses a certain elastic friction on the side of the mosquito coil cover to block subsequent mosquito coil covers. Since subsequent mosquito coil covers have no adsorption force, they are easily blocked by the appropriate elastic friction of the inclined plate 112, preventing the problem of mosquito coil covers stacking and easily detaching.

[0026] The closing mechanism 2 includes a monitor 21, a cover presser 22, a motor 23, and a transmission bar 24. Motors are located at both ends of the transmission bar 24, driving the mosquito coil container via their outputs. The monitor 21 contains two infrared sensors, one above the other. A blocking rod is located at the position of the slide plate 4, and this blocking rod is opened and closed by two small motors installed inside the slide plate 4. A semi-circular groove is located above the monitor 21 on the slide plate 4, and the upper and lower infrared sensors of the monitor 21 are located in the semi-circular groove. The mosquito coil cover is located in a groove. When the lower infrared sensor of the monitor 21 detects that the mosquito coil bucket is being transported to the right from the transmission bar 24, the electrical signal controls the small motor to release the obstruction of the mosquito coil cover in the slide plate 4. After the obstruction bar opens and closes, the mosquito coil cover tilts and falls from the slide plate 4 onto the mosquito coil bucket. The motor 23 is located on both sides of the upper end of the conveyor table 6. The output end of the motor 23 drives the cover presser 22 to rotate. The cover presser 22 rotates to the position of the fallen mosquito coil cover, so that the cover presser 22 presses the mosquito coil cover onto the upper end of the mosquito coil bucket.

[0027] Furthermore, the transmission of the transmission bar 24 is controlled by the sensor 21. After the sensor 21 detects the passage of the mosquito coil bucket, the transmission bar 24 stops transmitting after transmitting the mosquito coil bucket for one body length. At this time, the tilt position of the slide plate 4 corresponds to the mosquito coil bucket on the surface of the transmission bar 24, and the rotation position of the cover press 22 corresponds to the mosquito coil bucket. The cover press 22 can rotate to a horizontal state. Through the synchronous movement of the two small motors inside the slide plate 4, the blocking rod opens and closes, and then the mosquito coil cover slides from the slide plate 4 to the top of the mosquito coil bucket.

[0028] Furthermore, the blocking rod quickly resets after being rotated and opened by a small motor, blocking the mosquito coil cover on the subsequent slide plate 4 again. At this time, the infrared sensor of the monitor 21 can sense that the mosquito coil cover has detached from the semi-circular groove of the slide plate 4. Then, through the electrical signal connection between the monitor 21 and the motor 23, the motor 23 drives the cover presser 22 to rotate after sensing that the mosquito coil cover has detached from the slide plate 4, so that the cover presser 22 presses the fallen mosquito coil cover onto the mosquito coil bucket.

[0029] The cover presser 22 is equipped with a fixing rod 221, a connecting plate 222, a sponge layer 223, and a second rotating rod 224. The second rotating rod 224 is located at the output end of the motor 23. The connecting plate 222 is fixedly connected through the second rotating rod 224. There are three fixing rods 221, which are arranged horizontally. The fixing rod 221 in the middle position is larger than the fixing rods 221 on both sides. The outer side of the fixing rod 221 is attached to the sponge layer 223. The bottom of the sponge layer 223 is located at the same horizontal position. After the motor 23 rotates, under the elasticity of the sponge layer 223, the fixing rod 221 in the middle position presses against the middle of the mosquito coil cover, and the fixing rods 221 on both sides press the mosquito coil cover elastically through the sponge layer 223.

[0030] The monitoring head 15 and the telescopic device 13 are electrically connected to each other. When the monitoring head 15 cannot detect the mosquito coil cover inside the interception rod 14, the telescopic device 13 stops driving the negative pressure head 12 to work. The conveyor platform 3 is equipped with a first rotating rod 301 and a conveyor belt 302. There are two first rotating rods 301, one of which is rotated by a motor, and the first rotating rod 301 drives the two conveyor belts 302 to drive the transmission. The position between the two conveyor belts 302 is hollow. The telescopic device 13 drives the negative pressure head 12 to move upward between the two conveyor belts 302.

[0031] The adsorption mechanism 1 is provided in two parts. The adsorption mechanism 1 is set on a vertical conveyor 3 and one of the parallel conveyor 3s. The two adsorption mechanisms 1 are respectively on the same side of the conveyor 6. The mosquito coil cover on the vertical conveyor 3 is transferred to one of the parallel conveyor 3s.

[0032] Furthermore, when the monitoring head 15 does not detect the mosquito coil cover, the telescopic device 13 stops operating. At this time, it is necessary to add the mosquito coil cover into the adsorption mechanism 1. The positions of the two adsorption mechanisms 1 facilitate the addition of the mosquito coil cover to the five ring-shaped interception bars 14 on the same side, avoiding the need for personnel to walk back and forth to add the mosquito coil cover to the two conveyor platforms 6.

[0033] In this invention, under the rotation of the cover presser 22, the rightmost fixing rod 221 first presses down on the mosquito coil cover, locking one side of the mosquito coil cover into the upper edge of the mosquito coil bucket, and limiting one side of the mosquito coil cover. Since the thickness of the sponge layer 223 in the middle position is the smallest, the pressing force of the middle fixing rod 221 is the greatest. Under the pressure of the middle fixing rod 221 and the sponge layer 223, the middle position of the mosquito coil cover is limited and supported, preventing the mosquito coil cover from sliding easily. After the connecting plate 222 is rotated to a horizontal position by the second rotating rod 224, the fixing rods 221 on both sides press the mosquito coil cover to the upper edge of the mosquito coil bucket under the elasticity of the sponge layer 223. Thus, through the rotation of the cover presser 22, the mosquito coil cover is accurately covered on the mosquito coil bucket when it is pressed down, preventing the mosquito coil cover from sliding easily and falling off the mosquito coil bucket.

[0034] The above description is merely a preferred embodiment of this utility model, and therefore cannot be used to limit the scope of this utility model. All equivalent changes and modifications made in accordance with the scope of this utility model and the contents of the specification should still fall within the scope of this utility model.
