Description

Technical Field

[0001] The present invention specifically relates to a fully automatic bath cap packaging machine. Background Art

[0002] A bath cap is a waterproof cap used to wrap the hair and ears when taking a shower with a shower head to prevent the hair from getting wet or the ears from getting water in easily. It is made of waterproof materials and a tightening rubber band. At present, the production of bath caps has adopted mechanized automatic production, that is, the so-called bath cap machine.

[0003] The bath caps produced by the bath cap machine need to be stored in a packaging bag according to a certain quantity for convenient transportation and sales. This process can be simply referred to as "bath cap packaging". At present, this step of "bath cap packaging" is all achieved manually. Workers open the bag body by themselves, manually put the piled bath caps into the packaging bag, and then use glue or a hot pressing tool to seal the bag mouth. The work efficiency is extremely low, and the labor intensity is relatively large, which cannot meet the requirements of high-speed production of bath caps. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a fully automatic bath cap packaging machine in view of the deficiencies of the above-mentioned prior art, which realizes automatic bath cap packaging, greatly improves the production efficiency, and reduces the labor cost; further, through the collaborative work of the bag opening and adsorption assembly and the side positioning assembly, the deflection of the bag mouth is avoided, the production efficiency and the flatness of the bag mouth are effectively improved, and the labor cost is reduced.

[0005] To achieve the above object, the present invention provides the following technical solution: A fully automatic bath cap packaging machine, characterized in that: it includes a frame, and a bath cap feeding device for transporting bath caps, a bag feeding device for transporting bag bodies, and a bag opening device for receiving bath caps and bag bodies are provided on the frame. The bag opening device is used to close the bag mouth or open the bag mouth of the bag body so that bath caps can be put into the bag body, and a bag sealing device for sealing the bag mouth is further provided above the bag opening device on the frame.

[0006] Adopting the above technical solution, the bath cap feeding device automatically transports the piled bath caps, sorts and groups them according to a preset quantity. The bag feeding device automatically provides packaging bags and transports them to the bag opening device. The bag opening device receives the bag body provided by the bag feeding device, opens the packaging bag, automatically puts the bath caps into the bag, and then closes the bag mouth of the packaging bag after completion. The bag sealing device automatically performs a sealing operation after the packaging bag is filled with bath caps. After the sealing is completed, the bag body can be taken away. This solution effectively solves the problems existing in the traditional manual packaging mode, realizes automatic bath cap packaging, greatly improves the production efficiency, reduces the labor cost, and at the same time improves the working environment, liberating employees from repetitive and labor-intensive work.

[0007] The above-mentioned fully automatic bath cap packaging machine can be further configured as follows: the bag opening device includes two groups of bag opening adsorption components symmetrically arranged on two surfaces of the bag body, and two groups of side positioning components symmetrically arranged on two sides of the bag body and capable of reciprocatingly moving towards the side edges of the bag body. The two groups of bag opening adsorption components and the two groups of side positioning components are arranged in a criss-cross manner. The bag opening adsorption components are linked with a driving component capable of driving the bag opening adsorption components to reciprocatingly move towards the surface of the bag body.

[0008] With the above technical solution, during the bag opening process, the bag opening adsorption components and the side positioning components work together. The two groups of bag opening adsorption components first adsorb the front and back of the bag, and then the side positioning components guide and position the two side edges of the bag to ensure that the bag remains stable during the bag opening process, effectively avoiding deflection of the bag during the bag opening process. Not only can the function of bag opening be realized, but also the shapes of the two sides of the bag body at the heat-sealed bag mouth after heat sealing are regular, forming a normal sealing shape, thereby ensuring the flatness of the bag mouth.

[0009] The above-mentioned fully automatic bath cap packaging machine can be further configured as follows: the side positioning component includes two groups of symmetrically arranged clamping plates, a finger cylinder that is simultaneously linked with the two groups of clamping plates and controls the opening and closing of the two groups of clamping plates. The finger cylinder is linked with a first cylinder seat, the first cylinder seat is linked with a first cylinder, the body of the first cylinder is fixedly connected with a lifting cross plate, the end of the lifting cross plate is linked with a moving driving mechanism, guide rods are arranged at both ends of the first cylinder seat, and the lifting cross plate is provided with guide holes corresponding to the guide rods and slidably matched with the guide rods. The moving driving mechanism includes a first belt and a first servo motor. The first belt is linked with the first servo motor through a belt pulley. A connecting block is fixed on the first belt, the connecting block is connected with the end of the lifting cross plate, the connecting block is also linked with a first slider, the first slider is slidably matched with a first slide rail, and the first slide rail is parallel to the first belt.

[0010] With the above technical solution, the finger cylinder is used to control the opening and closing actions of the clamping plates to realize the clamping and release of the side edges of the bag body. The first cylinder is used to control the lifting of the finger cylinder, that is, to control the lifting of the clamping plates to adapt to different specifications and types of bag bodies or working conditions. The sliding fit between the guide rod and the guide hole ensures the smooth and accurate lifting movement of the clamping plates, avoiding deviation of the clamping plates during the lifting process. The first servo motor in the moving driving mechanism drives the connecting block to move through the first belt, so that the clamping plates approach or move away from the bag body. It is used to control the finger cylinder, the clamping plates, the first cylinder seat, the first cylinder, and the lifting cross plate to approach or move away from the bag body synchronously. It should be noted that during the bag opening process, after the clamping plates clamp the side edges of the bag body, they will gradually move towards the center of the bag body to adapt to the change in the width of the bag mouth and avoid excessive stretching deformation at the bag mouth.

[0011] The above-mentioned fully automatic bath cap packaging machine can be further set as follows: The bag opening and adsorption assembly includes a bag opening suction nozzle and a first connecting rod linked with the bag opening suction nozzle. The first connecting rod is slidably fitted with a positioning ring. A limiting step is provided at the end of the first connecting rod close to the positioning ring. A spring is sleeved on the outer periphery of the first connecting rod. The two ends of the spring are respectively in contact connection with the positioning ring and the suction nozzle. The positioning ring is linked with a driving assembly. The driving assembly includes a first mounting plate and a second air cylinder linked with the first mounting plate. A strip-shaped hole is provided on the first mounting plate. The positioning ring is clamped in the strip-shaped hole.

[0012] With the above technical solution, the second air cylinder drives the positioning ring to move towards the bag through the first mounting plate, and the positioning ring drives the bag opening suction nozzle to move forward through the first connecting rod and the spring. By setting the strip-shaped hole, the position of the positioning ring can be adjusted according to the actual situation. The spring provides elastic buffering during the movement of the first connecting rod, ensuring the smooth contact between the bag opening suction nozzle and the surface of the packaging bag, and avoiding damage to the packaging bag or unstable adsorption caused by hard contact. The cooperation of the limiting step and the positioning ring limits the movement range of the first connecting rod, preventing the bag opening suction nozzle from overextending or retracting, that is, avoiding the first connecting rod from disengaging from the positioning ring.

[0013] The above-mentioned fully automatic bath cap packaging machine can be further set as follows: The bath cap feeding device includes a bath cap conveyor belt, a material separating mechanism for automatically sorting bath caps, and a blanking mechanism distributed at the discharge end of the bath cap conveyor belt. The blanking mechanism is used to transport the sorted bath caps into the bag opening mechanism. The bath cap conveyor belt is linked with a fourth servo motor through a sprocket transmission assembly.

[0014] With the above technical solution, the fourth servo motor drives the bath cap conveyor belt to move through the sprocket transmission assembly, and the bath caps are automatically transported through the bath cap conveyor belt. The material separating mechanism automatically spaces and sorts the bath caps, not only ensuring that the bath caps are arranged according to the preset quantity and order, but also preventing excessive accumulation of bath caps. The sorted bath caps are transported to the blanking mechanism. The blanking mechanism accurately transports the sorted bath caps into the bag opening device, ensuring that the bath caps can smoothly enter the packaging bag.

[0015] The above-mentioned fully automatic bath cap packaging machine can be further set as follows: The material separating mechanism includes a baffle and a sixth air cylinder. A second air cylinder seat is installed above the bath cap conveyor belt. The body of the sixth air cylinder is fixed on the second air cylinder seat, and the output end is hinged with a swing arm. The baffle is fixed on the swing arm. A second connecting rod is hinged in the middle of the swing arm. The end of the second connecting rod far away from the swing arm is linked with a support seat, and the support seat is fixed on the second air cylinder seat.

[0016] With the above technical solution, when the shower cap conveyor belt drives the shower caps past the material separating mechanism, the output rod of the sixth cylinder extends and retracts to drive the swing arm, and the swing arm swings around its hinge joint with the second connecting rod, thereby driving the baffle plate to perform the material separating operation. The baffle plate separates the shower caps into a preset number of groups, and each group of shower caps is neatly arranged and separated on the conveyor belt. The shower caps not blocked by the baffle plate continue to move forward with the shower cap conveyor belt until they enter the next process, so that the shower caps on the shower cap conveyor belt do not interfere with each other.

[0017] The above-mentioned fully automatic shower cap packaging machine can be further configured as follows: the blanking mechanism includes a blanking hopper distributed at the discharge end of the shower cap conveyor belt, and a seventh cylinder that is linked to the blanking hopper and controls the reciprocating movement of the blanking hopper towards the bag body; a material receiving port corresponding to the shower cap conveyor belt is provided on the side of the blanking hopper, and a discharge port is provided below; two sets of symmetrically arranged nozzles are provided at the discharge port of the blanking hopper, the middle of the nozzle is hinged to the blanking hopper, one end of the nozzle is hinged with a third connecting rod, the end of the third connecting rod away from the nozzle is linked with a cylinder connecting plate, and the cylinder connecting plate is linked with an eighth cylinder, and the body of the eighth cylinder is fixed on the blanking hopper; a pushing plate is arranged in the blanking hopper, and the pushing plate is linked with a ninth cylinder for controlling the sliding of the pushing plate in the blanking hopper, and the body of the ninth cylinder is fixed on the blanking hopper.

[0018] With the above technical solution, the shower caps enter the blanking hopper from the material receiving port. When discharging is required, the seventh cylinder first controls the overall downward movement of the blanking hopper until it is close to the bag opening, so that the shower caps can fall into the bag more accurately. The eighth cylinder drives the third connecting rod to move through the cylinder connecting plate, and the third connecting rod pulls the nozzle, and the nozzle swings around its hinge joint with the blanking hopper, thereby realizing the opening of the nozzle, and the shower caps fall into the packaging bag. To avoid the situation that some shower caps remain in the blanking hopper, the ninth cylinder drives the pushing plate to move downward, pushing the shower caps into the package, eliminating the situation of shower cap residue, thereby improving the accuracy of the number of shower cap packaging bags. After the discharging is completed, the seventh cylinder then controls the overall upward movement of the blanking hopper, away from the bag opening, aiming to prevent interference with components such as nozzles when the bag mouth is heat-sealed by the bag sealing device. At the same time, this blanking mechanism can also improve the overall packaging efficiency. The blanking hopper can store shower caps. Once the bag mouth is opened, there is no need to wait for the transportation of the shower caps, and the shower caps can be immediately sent into the bag.

[0019] The above-mentioned fully automatic shower cap packaging machine can be further configured as follows: the bag sealing device includes symmetrically distributed copper knives and plastic strips, the copper knives are linked with a third cylinder that can drive the copper knives to reciprocate towards the bag body, and the plastic strips are linked with a fourth cylinder that can drive the plastic strips to reciprocate towards the bag body.

[0020] With the above technical solution, the third cylinder drives the copper knife to move towards the bag mouth of the packaging bag until the copper knife contacts the bag mouth. The fourth cylinder drives the plastic strip to move towards the bag mouth of the packaging bag and cooperates with the copper knife to complete the heat sealing operation. The copper knife has good thermal conductivity and wear resistance, can quickly and evenly heat seal the bag mouth of the packaging bag, and improve the heat sealing quality. The plastic strip cooperates with the copper knife to provide the contact surface required for heat sealing, ensure the uniformity of heat sealing. At the same time, the plastic strip can buffer the contact force between the copper knife and the packaging bag, avoid damage to the packaging bag caused by hard contact, and improve the uniformity and stability of heat sealing.

[0021] The above-mentioned full-automatic bath cap packaging machine can be further set as follows: the bag feeding device includes a bag feeding adsorption component and a second mounting plate linked to the bag feeding adsorption component. The second mounting plate is linked with a fifth cylinder. The body of the fifth cylinder is linked with a rotating shaft. The rotating shaft is hinged on the frame, and the end of the rotating shaft is linked with a second belt through a pulley. The second belt is linked with a second servo motor through a pulley. The bag feeding mechanism further includes a bag frame installed on the frame.

[0022] With the above technical solution, the second servo motor drives the fifth cylinder to rotate through the second belt and the rotating shaft until the bag feeding adsorption component is aligned with the bag frame. Then the fifth cylinder drives the bag feeding adsorption component to extend to suck the bag body, and then the fifth cylinder drives the bag feeding adsorption component to reset. Then the second servo motor drives the fifth cylinder to rotate back through the second belt and the rotating shaft, and the fifth cylinder drives the bag feeding adsorption component to extend until the bag opening adsorption component sucks the bag body, and the bag feeding adsorption component releases the bag body. At the same time, the bag feeding device can also improve the overall packaging efficiency. During the operation of the bag opening device, the bag feeding adsorption component can transport the next group of bag bodies to the side of the bag opening device. Once the sealing work is completed, without waiting for the transportation of the bag body, the bag body can be immediately sent into the bag opening device.

[0023] The above-mentioned full-automatic bath cap packaging machine can be further set as follows: an output belt distributed below the bag opening device is further provided on the frame. Both ends of the output belt are respectively linked with roller shafts. One group of roller shafts is linked with a third servo motor through a sprocket transmission component. A baffle is provided on the side of the output belt.

[0024] With the above technical solution, the third servo motor drives the output belt to rotate through the roller shafts, and automatically transports the packaged and heat-sealed packaging bags away. It further realizes full automation without the need for manual removal of the packaged bag bodies.

[0025] The beneficial effects of the present invention: It realizes the full-automatic process from bath cap transportation, sorting, grouping, bagging to sealing, effectively solving the problems of low efficiency and high labor intensity of traditional manual packaging. Through the collaborative work of the bag opening adsorption component and the side positioning component, it ensures the stability of the bag during the bag opening process, avoids deflection, and improves the flatness of the bag mouth and the heat sealing quality.

The two groups of bag opening adsorption components c1 and the two groups of side positioning components c2 are arranged in a crisscross manner. The bag opening adsorption component c1 is linked with a driving component capable of driving the bag opening adsorption component c1 to reciprocatingly move towards the surface of the bag body. During the bag opening process, the bag opening adsorption component c1 and the side positioning component c2 work together. The two groups of bag opening adsorption components c1 first adsorb the front and back of the bag, and then the side positioning components c2 guide and position the two sides of the bag to ensure that the bag remains stable during the bag opening process, effectively avoiding the deflection of the bag during the bag opening process, not only realizing the function of bag opening, but also making the shape of the sealing part and the two sides of the bag body regular after heat sealing of the bag mouth, forming a normal sealing shape, thus ensuring the flatness of the bag mouth.

The first cylinder c6 is used to control the lifting of the finger cylinder c4, that is, to control the lifting of the clamping plate c3 to adapt to different specifications and types of bag bodies or working conditions. The sliding fit between the guide rod c8 and the guide hole ensures the smooth and accurate lifting movement of the clamping plate c3 and prevents the clamping plate c3 from shifting during the lifting process. The first servo motor c10 in the moving drive mechanism drives the connecting block c11 to move through the first belt c9, so that the clamping plate c3 moves closer to or away from the bag body. It is used to control the finger cylinder c4, the clamping plate c3, the first cylinder seat c5, the first cylinder c6, and the lifting cross plate c7 to move closer to or away from the bag body synchronously.

The spring provides elastic buffering during the movement of the first connecting rod c15, ensuring the smooth contact between the bag-opening suction nozzle c14 and the surface of the packaging bag, and avoiding damage to the packaging bag or unstable adsorption caused by hard contact. The cooperation between the limiting step c17 and the positioning ring c16 limits the movement range of the first connecting rod c15, preventing the bag-opening suction nozzle c14 from overextending or retracting, that is, avoiding the first connecting rod c15 from disengaging from the positioning ring c16.

The third servo motor e1 drives the discharge belt e to rotate through the roller shafts, automatically transporting the packaged and heat-sealed packaging bags away.

[0039] The specific working principle of this embodiment is as follows: The fourth servo motor a2 drives the bath cap conveyor belt a1 to move through the sprocket transmission assembly, and the bath caps are automatically transported through the bath cap conveyor belt a1.

[0040] When the bath cap conveyor belt a1 drives the bath caps to pass through the material separation mechanism, the output rod of the sixth air cylinder a4 extends and retracts to drive the swing arm a6. The swing arm a6 swings around its hinge joint with the second connecting rod a7, thereby driving the baffle a3 to perform the material separation operation. The baffle a3 separates the bath caps into a preset number of groups. Each group of stacked bath caps is neatly arranged and separated on the conveyor belt. The stacked bath caps not blocked by the baffle a3 continue to move forward with the bath cap conveyor belt a1.

[0041] The shower cap enters the hopper a9 from the material receiving port a11. When discharging is required, the seventh cylinder a10 first controls the overall downward movement of the hopper a9 until it is close to the bag mouth, so that the shower cap can fall into the bag more accurately. Immediately afterwards, the eighth cylinder a15 drives the third connecting rod a13 to move through the cylinder connecting plate a14, and the third connecting rod a13 pulls the nozzle a12. The nozzle a12 swings around its hinge a6 with the hopper a9, and the nozzle a12 opens, and the shower cap falls into the packaging bag. At the same time, the ninth cylinder a17 drives the pusher plate a16 to move downward, pushing the shower cap into the package to prevent the shower cap from remaining in the hopper a9. After the discharging is completed, the seventh cylinder a10 controls the overall upward movement of the hopper a9 away from the bag mouth, aiming to prevent interference between the bag sealing device d and components such as the nozzle a12 when heat-sealing the bag mouth.

[0042] At the same time, the second servo motor b7 drives the fifth cylinder b3 to rotate through the second belt b5 and the rotating shaft b4 until the bag feeding adsorption assembly b1 is aligned with the bag frame b6. The fifth cylinder b3 drives the bag feeding adsorption assembly b1 to extend to suck the bag body, and then the fifth cylinder b3 drives the bag feeding adsorption assembly b1 to reset. Then the second servo motor b7 drives the fifth cylinder b3 (the bag feeding adsorption assembly b1 follows) to rotate back through the second belt b5 and the rotating shaft b4, and then the fifth cylinder b3 drives the bag feeding adsorption assembly b1 to extend until the bag opening adsorption assembly c1 sucks the bag body and the bag feeding adsorption assembly b1 releases the bag body.

[0043] The bag opening adsorption assembly c1 is driven by the driving assembly to bring the bag opening suction nozzle c14 close to the surface of the packaging bag and suck the bag body to realize the bag opening operation. At the same time, the side positioning assembly c2, through the coordinated action of components such as the finger cylinder c4 and the moving driving mechanism, clamps the side of the packaging bag with the clamping plate c3 to prevent the bag body from deflecting during bag opening. During the bag opening process, when the clamping plate c3 clamps the side of the bag body, the moving driving mechanism will gradually drive the clamping plate c3 to move towards the center of the bag body. At this time, the clamping plate c3 does not release the side of the bag body, adapting to the shape change of the bag mouth opening and avoiding excessive stretching of the bag mouth. Until the bag is filled with products, the bag opening adsorption assembly c1 closes the bag mouth. At the same time, the moving driving mechanism will gradually drive the clamping plate c3 to move away from the center of the bag body and gradually reset until the bag mouth is closed.

[0044] After the bag opening is completed, the bag sealing device d drives the copper knife d1 and the plastic strip d2 to perform heat sealing operation on the bag mouth through the third cylinder d3 and the fourth cylinder d4.

[0045] After heat sealing is completed, the bag body falls onto the discharge belt e. The discharge belt e is driven by the third servo motor e1 to transport the packaging bag that has completed the bag opening and heat sealing operations. At the same time, the baffle e2 ensures the stability of the packaging bag during transportation.
