Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, and more specifically, to a cotton swab pushing and bagging mechanism. Background Technology

[0002] Currently, cotton swab packaging machines suffer from significant process compatibility issues. For example, existing automated equipment typically opens the swab bag directly and pushes the cotton swab material into it during filling. However, because the cotton swab material tends to scatter, it can interfere with the bag opening, leading to quality problems during filling.

[0003] Furthermore, when traditional equipment uses a U-shaped trough for material feeding, the U-shaped trough needs to maintain a close spacing of 50mm to meet the requirements for swab delivery. This is severely mismatched with the 120mm standard spacing required for subsequent bone strip bag packaging. This spacing difference means that the pushing mechanism cannot directly use the same structural parameters as the U-shaped trough, necessitating a complex spacing conversion. Simultaneously, when the equipment adopts a dual-station design, setting the height of the U-shaped trough to the same height as the bone strip bag results in low overall space utilization, leading to a bulky and cumbersome mechanical structure. This structural contradiction not only increases manufacturing costs but also easily causes quality problems such as swab scattering and bag opening interference during operation. Existing technologies lack effective transition mechanisms, making it difficult to achieve a compact equipment layout while ensuring packaging accuracy. Therefore, existing technologies urgently need improvement to address these issues. Summary of the Invention

[0005] A cotton swab pushing and bagging mechanism is adapted to connect to a cotton swab conveyor belt with a storage trough, comprising: a cotton swab pushing component, a transfer transition component, and a pressure tongue insertion and opening component; wherein, the pressure tongue insertion and opening component is adapted to open the rib bag at the bagging station to facilitate the pushing of cotton swab material; the transfer transition component includes a motion mechanism and a transition cavity connected to the motion mechanism, the transition cavity being adapted to receive cotton swab material from the storage trough of the cotton swab conveyor belt and move to the bagging station via the motion mechanism, and causing a portion of the transition cavity to enter the rib bag; the cotton swab pushing component includes a first pushing mechanism and a second pushing mechanism, the first pushing mechanism being adapted to push the cotton swab material in the storage trough into the transition cavity, and the second pushing mechanism being adapted to push the cotton swab material transferred in the transition cavity into the rib bag.

[0006] Furthermore, the tongue-pressing and spreading assembly is provided with at least two sets of bag-spreading mechanisms to simultaneously spread the two bone strip bags.

[0007] Furthermore, the transition cavity includes a fixed transition cylinder and a movable transition cylinder, and the motion mechanism includes a lifting mechanism and a mounting assembly disposed on the lifting mechanism. The mounting assembly is provided with a transverse mechanism to connect the movable transition cylinder. The transverse mechanism is configured to adjust the distance between the movable transition cylinder and the fixed transition cylinder, and to adapt the distance between the movable transition cylinder and the fixed transition cylinder to the distance between the two adjacent storage troughs when receiving materials, and to adapt the distance between the movable transition cylinder and the fixed transition cylinder to the distance between the two bone strip bags when receiving materials. The lifting mechanism is adapted to adjust the height of the transition cavity to be flush with the height of the storage trough when receiving materials, and to make the height of the transition cavity flush with the height of the bone strip bag when pushing materials.

[0008] Furthermore, a material blocking mechanism is provided at the end of the transition cavity away from the bone strip bag. The material blocking mechanism includes a material blocking block and a material blocking cylinder. The material blocking cylinder is adapted to drive the material blocking block to cover the opening of the transition cavity during the process of the transition cavity being transferred from the storage tank to the bone strip bag to prevent the cotton swab material from slipping back.

[0009] Furthermore, the tongue-pressing extension and opening assembly includes upper and lower tongue-pressing blocks and upper and lower cylinders for driving the upper and lower tongue-pressing blocks to close or open with each other, and front and rear extension cylinders for driving the upper and lower tongue-pressing blocks and the upper and lower cylinders to move. The front and rear extension cylinders are adapted to allow the upper and lower tongue-pressing blocks to first extend into the bone strip bag in the closed state and then expand up and down, so as to facilitate the extension of the transition cavity.

[0010] Furthermore, the upper and lower pressure tongue blocks include an upper pressure tongue and a lower pressure tongue, the upper pressure tongue and the lower pressure tongue are configured in an arched shape, and the end facing the bone strip bag is configured in a conical shape so as to extend into the bone strip bag.

[0011] Furthermore, two sets of guide post and guide sleeve mechanisms are respectively provided on the upper and lower pressure tongues to improve stability.

[0012] Furthermore, the upper and lower cylinders are connected to the mounting bracket by screws and limiting bolts, and are configured to adjust the unfolding distance of the upper and lower pressure tongue blocks by adjusting the limiting bolts.

[0013] Furthermore, the cotton swab insertion component also includes servo modules respectively disposed on both sides of the tongue depressor insertion and opening component. Each servo module is provided with a slide rail assembly. The first insertion mechanism and the second insertion mechanism are connected to the slide rail assembly through a movable plate. The movable plate is driven by a telescopic cylinder to drive the first insertion mechanism and the second insertion mechanism to perform insertion and withdrawal actions.

[0014] Furthermore, the first pushing mechanism is provided with a first pushing block of the same height as the storage trough, and the second pushing mechanism is provided with a second pushing block of the same height as the bone strip bag.

[0015] Beneficial effects: By setting up a transfer transition component to realize the spacing conversion between the storage tank and the bone strip bag, and setting up a tongue extension and opening component to ensure that the transition cavity accurately extends into the bag opening, the problem of bulky structure, cotton swabs scattering and bag opening interference of traditional equipment is solved. It has the advantages of compact structure and high packaging accuracy. Attached Figure Description

Detailed Implementation

[0017] Combination Figures 1 to 4As shown, this embodiment provides a cotton swab pushing and bagging mechanism, suitable for connecting to a cotton swab conveyor belt with a storage trough, including: a cotton swab pushing component 1, a transfer transition component 2, and a pressure tongue insertion and opening component 3; wherein, the pressure tongue insertion and opening component 3 is adapted to open the rib bag at the bagging station to facilitate the pushing of cotton swab material; the transfer transition component 2 includes a motion mechanism 23 and a transition cavity connected to the motion mechanism 23, the transition cavity is adapted to receive cotton swab material from the storage trough of the cotton swab conveyor belt, and move to the bagging station through the motion mechanism 23, so that the transition cavity part enters the rib bag; the cotton swab pushing component 1 includes a first pushing mechanism 13 and a second pushing mechanism 14, the first pushing mechanism 13 is adapted to push the cotton swab material in the storage trough into the transition cavity, and the second pushing mechanism 14 is adapted to push the cotton swab material transferred in the transition cavity into the rib bag. It should be noted that the device also includes a bag-opening component for opening the bone strip bag.

[0018] The tongue-pressing and expanding assembly 3 is located on one side of the cotton swab conveyor belt. It can be implemented using a cylinder-driven tongue-pressing block structure, expanding by extending into the bag in a closed state. The transfer and transition assembly 2 is located on the other side of the cotton swab conveyor belt. Its motion mechanism 23 is a drive device for adjusting the spatial position. It can be a combination of a lifting module and a lateral movement module, enabling the transition cavity to achieve vertical height matching and horizontal spacing conversion. The transition cavity refers to the channel structure for temporarily storing cotton swabs. It can be implemented using a split cylindrical structure, aligning with the storage trough when receiving materials and partially extending into the bone strip bag when pushing materials. The first pushing mechanism 13 and the second pushing mechanism 14 are the execution components that perform the pushing action in stages. Specifically, they can be implemented using a combination of a pushing block and a linear drive module structure, achieving material transfer between the storage trough and the transition cavity, and between the transition cavity and the bone strip bag through independent control. The transition cavity can be provided in one or more ways. This embodiment is illustrated by providing two transition cavities that can simultaneously fill two bone strip bags.

[0019] When the cotton swab conveyor belt moves the storage trough to the receiving position, the first pushing mechanism 13 pushes the cotton swabs laterally into the transition cavity. The lifting mechanism 24 raises or lowers the transition cavity to be level with the height of the bone strip bag, and the lateral movement mechanism 26 adjusts the spacing of the other transition cavity to align it with the double-station bag body. The pressure tongue extends into the opening assembly 3 to open the bag opening before the transition cavity is in place, and the second pushing mechanism 14 pushes the cotton swabs in the transition cavity into the bone strip bag. The transition cavity maintains a matching spacing with the storage trough during the receiving stage, and adapts to the spacing of the bone strip bag through position adjustment during the pushing stage. The entire process eliminates structural interference through step-by-step pushing and spatial transformation.

[0020] This solution achieves flexible adaptation to different workstations through the spacing conversion function of the transition cavity. The height of the transition cavity is dynamically adjusted by the lifting mechanism 24, matching different height requirements during the material receiving and pushing stages. Furthermore, a stable bag opening positioning benchmark is established before pushing by the pressure tongue component, effectively resolving structural conflicts caused by differences in the spacing between the two workstations and ensuring reliable material transfer between the conveyor belt and the packaging bag. The transition cavity, acting as an intermediate carrier, avoids the swabs scattering caused by direct pushing and reduces the overall height of the equipment through its position adjustment function. The timing coordination between the pressure tongue opening component and the pushing action ensures accurate insertion of the swabs into the bag, improving the packaging yield.

[0021] Combination Figure 1 and Figure 4 As shown, the tongue-extending and opening assembly 3 is equipped with at least two sets of bag-opening mechanisms to simultaneously open two ribbed bags. The two sets of bag-opening mechanisms refer to two independently controllable bag-opening execution units, specifically implemented using a symmetrically distributed upper and lower tongue blocks (32 blocks) combined with cylinders. Their function is to simultaneously open the two ribbed bags, thus adapting to the dual-station bagging requirements. When the equipment is in dual-station operation, the two sets of bag-opening mechanisms correspond to the bagging stations of the two ribbed bags respectively. Before the pushing action begins, the two sets of bag-opening mechanisms can use cylinders to simultaneously extend the combined tongue blocks into the corresponding ribbed bags, and then open the bag opening to a predetermined distance through an unfolding action. During this process, the two sets of bag-opening mechanisms are independently controlled and do not interfere with each other, ensuring that the bag-opening actions of the two stations are completed synchronously.

[0022] Combination Figure 1 and Figure 3 As shown, in this embodiment, the intermediate transition component 2 of the cotton swab pushing into the bagging mechanism includes a fixed transition cylinder 21 and a movable transition cylinder 22. The motion mechanism 23 includes a lifting mechanism 24 and an installation component 25 disposed on the lifting mechanism 24. A transverse movement mechanism 26 is provided on the installation component 25 to connect the movable transition cylinder 22. The transverse movement mechanism 26 is configured to adjust the distance between the movable transition cylinder 22 and the fixed transition cylinder 21, and to adapt the distance between the movable transition cylinder 22 and the fixed transition cylinder 21 and the distance between the two adjacent storage troughs respectively when receiving materials, and to adapt the distance between the movable transition cylinder 22 and the fixed transition cylinder 21 and the two bone strip bags respectively when receiving materials. The lifting mechanism 24 is adapted to adjust the height of the transition cavity to be flush with the height of the storage trough when receiving materials, and to make the height of the transition cavity flush with the height of the bone strip bag when pushing materials. By setting up a transition cavity spacing lifting mechanism and a tongue insertion and opening mechanism, the cotton swab is always inside the transition cylinder during the pushing process, ensuring that the cotton swab will not spread out during the pushing process. At the same time, the tongue insertion and opening mechanism also ensures that the transition cylinder will not interfere with the bag opening when it is inserted into the bag, thus preventing the bone strip bag from falling off.

[0023] Here, the fixed transition cylinder 21 refers to a cylindrical structure fixedly installed on the mounting assembly 25, used to receive and temporarily store cotton swabs transferred from the storage tank, and can hold a set number of cotton swabs. The movable transition cylinder 22 refers to a cylindrical structure that cooperates with the fixed transition cylinder 21 through a lateral movement mechanism 26. For example, it can achieve lateral displacement through a linear guide or slide module in conjunction with a cylinder assembly, used to adjust the distance between the movable transition cylinder 22 and the fixed transition cylinder 21 to adapt to the storage tank or bone strip bag at different work positions. The lifting mechanism 24 refers to a device that drives the mounting assembly 25 to move vertically, for example, it can use a cylinder or servo motor in conjunction with a lead screw structure, used to adjust the receiving height and pushing height of the transition cavity. The lateral movement mechanism 26 refers to a device that drives the movable transition cylinder 22 to move laterally, for example, it can use a pneumatic slide or electric push rod, used to adjust the distance between the movable transition cylinder 22 and the storage tank when receiving material, and to adjust its distance from the bone strip bag when pushing material.

[0024] The fixed transition cylinder 21 and the movable transition cylinder 22 together form a transition cavity. During the receiving stage, the lateral movement mechanism 26 drives the movable transition cylinder 22 to a position matching the distance to the storage trough. At this time, the lifting mechanism 24 raises the transition cavity to the same height as the storage trough, and the first pushing mechanism 13 pushes the cotton swab material from the storage trough into the transition cavity. After receiving the material, the lifting mechanism 24 lowers the transition cavity to the same height as the bone strip bag, while the lateral movement mechanism 26 adjusts the distance between the movable transition cylinder 22 and the fixed transition cylinder 21 to align with the opening position of the bone strip bag. Subsequently, the pressure tongue extends into the opening assembly 3 to open the bone strip bag, and the second pushing mechanism 14 pushes the cotton swab material from the transition cavity into the bone strip bag. Throughout this process, the transition cavity always contains the cotton swab material to prevent it from scattering, and by adjusting the height and spacing in stages, the problem of the distance and height difference between the storage trough and the bone strip bag is solved. The distance between the movable transition cylinder 22 and the fixed transition cylinder 21 is dynamically adjusted by the transverse movement mechanism 26, so that the same transition cavity can adapt to the different distance requirements of the storage tank and the bone strip bag. At the same time, the lifting mechanism 24 adjusts the height to avoid redundancy in the overall structure height, thereby optimizing the equipment layout while ensuring stable transfer of cotton.

[0025] In a preferred embodiment, a material-blocking mechanism is provided at the end of the transition cavity furthest from the rib bag. The material-blocking mechanism includes a material-blocking block 27 and a material-blocking cylinder 28. The material-blocking cylinder 28 is adapted to drive the material-blocking block 27 to cover the opening of the transition cavity during the process of receiving material from the storage tank and transferring it to the rib bag, preventing the cotton swabs from sliding backward. The material-blocking block 27 is a movable component that covers the opening of the fixed cavity, preventing the cotton swabs from sliding backward due to inertia during the movement of the transition cavity. The material-blocking cylinder 28 achieves the lifting and lowering action of the material-blocking block 27 through pneumatic control, ensuring that the opening is closed in a timely manner during the receiving and transfer stages. After the transition cavity receives the cotton swabs from the storage tank, the material-blocking cylinder 28 drives the material-blocking block 27 to press down, covering the opening of the transition cavity furthest from the rib bag. At this time, the transition cavity moves towards the bagging station via the motion mechanism 23. During the movement, the material-blocking block 27 continuously closes the opening, preventing the cotton swabs from sliding out backward due to inertia or vibration. When the transition cavity reaches the front of the bone strip bag, the baffle cylinder 28 controls the baffle block 27 to rise, releasing the seal on the opening and allowing the transition cavity to extend into the bone strip bag, enabling the second pushing mechanism 14 to push the cotton swab into the bag. This solution, through the linkage control of the baffle block 27 and the cylinder, dynamically seals the opening during the transfer phase, effectively solving the problem of cotton swabs slipping backward.

[0026] The tongue-operated expansion assembly 3 described in this embodiment includes upper and lower tongue blocks 32, upper and lower cylinders 34 for driving the upper and lower tongue blocks 32 to close or expand, and front and rear extension cylinders 35 for driving the upper and lower tongue blocks 32 and the upper and lower cylinders 34 to move. The front and rear extension cylinders 35 are adapted to allow the upper and lower tongue blocks 32 to first extend into the bone bag in the closed state and then expand up and down, so as to facilitate the insertion of the transition cavity. The upper and lower tongue blocks 32 refer to clamping components that achieve closure and expansion through mechanical structure. They can be made of metal or high-strength plastic into arched blocks, with their front ends set in a conical shape to facilitate insertion into the bag opening. This structure reduces interference and friction with the bag opening through the low cross-sectional shape in the closed state, thereby avoiding damage to the bone bag during the expansion process. The upper and lower cylinders 34 refer to the power devices that drive the movement of the upper and lower tongue blocks 32, and achieve synchronous closure and expansion of the tongue blocks through air circuit control. The function of the cylinder is to precisely control the expansion range of the tongue blocks, ensuring that the size of the bag opening after expansion matches the insertion path of the transition cavity. In this embodiment, the upper and lower pressure tongue blocks 32 include an upper pressure tongue block 31 and a lower pressure tongue block 32. The upper and lower cylinders 34 include an upper cylinder 33 connecting the upper pressure tongue block 31 and a lower cylinder 34 connecting the lower pressure tongue block 32, which are symmetrically arranged vertically. The front and rear extending cylinders 35 refer to the actuators that drive the pressure tongue blocks to move horizontally. Specifically, a linear cylinder with a guide rail can be used to push the closed pressure tongue blocks into the inside of the bone strip bag through a fixed stroke. This design ensures that the pressure tongue blocks are deeply inside the bag before the opening action, preventing the bag opening edge from shifting due to external force.

[0027] When the rib bag is positioned at the bagging station, the bag opening mechanism first opens the bag opening slightly. Then, the front and rear extending cylinders 35 push the closed upper and lower pressure tongues 32 horizontally, allowing their conical front ends to insert into the bag opening. Subsequently, the upper and lower cylinders 34 are activated, driving the upper pressure tongue 31 downward and the lower pressure tongue 32 upward simultaneously, thus expanding the opening of the rib bag to a predetermined size. At this point, the transition cavity, driven by the motion mechanism 23, extends into the expanded bag opening, completing the pushing action of the cotton swab material. The entire process, by executing the insertion and expansion actions in steps, solves the problem of interference between the transition cavity and the bag opening edge when directly inserted. By closing the insertion first and then dynamically expanding, the resistance during the insertion stage is reduced, and the precise expansion amplitude is achieved through cylinder control, avoiding bag deformation or material pushing failure due to mechanical interference, and ensuring that the transition cavity enters the bag without interference. Meanwhile, the closed-state design of the 32 upper and lower pressure tongues effectively reduces the stress concentration at the edge of the bag opening, preventing the bag from tearing or falling off during the opening process, thereby improving the bagging success rate and equipment operation stability.

[0028] In a preferred embodiment, the upper pressure tongue 31 and the lower pressure tongue 32 are arched, with the end facing the bone bag being tapered to facilitate insertion into the bag. The arched shape refers to the pressure tongue's cross-section having an upward or downward curved arc structure. This structure forms a stable support surface when the pressure tongue unfolds, preventing the bone bag opening from breaking due to excessive localized stress. The tapered shape refers to the pressure tongue's end forming a tapered slope or sharp angle, providing guidance as it inserts into the bone bag and reducing frictional resistance between the bag opening and the pressure tongue. When the upper and lower cylinders 34 drive the pressure tongue to unfold, the outer support surface of the arched structure evenly distributes the pressure on the bag opening, while the tapered end prevents the pressure tongue from scratching the inner wall of the bag opening during unfolding. Through this combination of arched and tapered design, the pressure tongue can quickly penetrate the bag opening and stably expand the bag opening space, providing a reliable channel for the insertion of the transition cavity.

[0029] Preferably, two sets of guide post and guide sleeve mechanisms are respectively provided on the upper pressure tongue 31 and the lower pressure tongue 32 to improve stability. The guide post and guide sleeve mechanism is a sliding guide structure composed of guide posts and guide sleeves, used to ensure the linear motion trajectory of the upper and lower pressure tongues 32 during the closing or unfolding process. Specifically, it can be implemented by using cylindrical guide posts in conjunction with copper guide sleeves, and lubrication grooves can be provided in the guide sleeves to reduce frictional resistance. This mechanism avoids movement jamming or positional deviation caused by uneven force by limiting the lateral displacement of the pressure tongue blocks. Further, the upper and lower cylinders 34 are respectively connected to the mounting frame by screws 36 and limiting bolts 37, and are configured to adjust the unfolding distance of the upper and lower pressure tongues 32 by adjusting the limiting bolts 37. The upper and lower cylinders 34 are movably connected to the mounting frame by screws 36. When it is necessary to adjust the unfolding distance of the upper and lower pressure tongues 32, the operator can loosen the limiting bolts 37 and move the cylinder position along the axial direction of the screws 36 to change the vertical distance between the upper and lower pressure tongues 32. After adjustment, tightening the limiting bolt 37 will fix the cylinder position. This structure allows the tongue-operated expansion assembly 3 to adapt to different heights of ribbed bags. For example, when the bag opening size increases, the expansion gap can be increased to prevent interference between the tongue block and the bag opening. Precise control of the tongue expansion gap is achieved through mechanical adjustment, enabling the equipment to quickly adapt to the packaging needs of different sized ribbed bags without replacing parts, thus improving the flexibility of the production line.

[0030] Combination Figure 1 and Figure 2 As shown, in this embodiment, the cotton swab pushing component 1 further includes servo modules 11 respectively disposed on both sides of the tongue depressor extension and opening component 3. Each servo module 11 is provided with a slide rail component 12. The first pushing mechanism 13 and the second pushing mechanism 14 are connected to the slide rail component 12 through a movable plate. The movable plate is driven by a telescopic cylinder 15 to drive the first pushing mechanism 13 and the second pushing mechanism 14 to perform pushing and withdrawing actions.

[0031] The servo module 11 is a drive unit capable of precise positioning and movement control, used to adjust the lateral position of the pushing mechanism according to the difference in distance between the storage trough and the rib bag. The movable plate is a connecting component that supports the pushing mechanism, used to integrate the first pushing mechanism 13 and the second pushing mechanism 14 onto the same moving unit. The telescopic cylinder 15 is used to control the switching of the pushing mechanism between the receiving position and the pushing position. When the cotton swabs in the storage trough need to be transferred, the slide rail assembly 12 is first driven to move laterally, aligning the first pushing mechanism 13 with the storage trough. At this time, the telescopic cylinder 15 pushes the movable plate to drive the first pusher block to push the cotton swabs into the transition cavity. After receiving the cotton swabs, the position of the slide rail assembly 12 is adjusted again, so that the second pushing mechanism 14 is aligned with the opening of the rib bag. The telescopic cylinder 15 drives the second pusher block to push the cotton swabs in the transition cavity into the bag. After the pushing action is completed, the movable plate returns to its initial position under the action of the cylinder to avoid interference with subsequent bagging actions. By combining the servo module 11 with the slide rail assembly 12, the dual push-in mechanism on the same movable plate can dynamically adjust its lateral position according to the workstation requirements. This solves the problem of adapting to different spacings, reduces the space occupied in the height direction of the equipment through the stacked layout, and lowers the overall height of the equipment through integrated design, making the production line layout more compact.

[0032] In this embodiment, the first pushing mechanism 13 is equipped with a first pushing block of the same height as the storage tank, and the second pushing mechanism 14 is equipped with a second pushing block of the same height as the bone strip bag. The first pushing block is a pushing component used to push the cotton swab material in the storage tank into the transition cavity. It can be implemented using a rectangular metal block with the same height and width as the inner wall of the storage tank. Matching its height to the storage tank prevents the cotton swabs from tilting or getting stuck during the pushing process. The second pushing block is a pushing component used to push the cotton swab material in the transition cavity into the bone strip bag, and can be the same size as the first pushing block. The first pushing block moves horizontally within the storage tank, its height being flush with the bottom of the storage tank, allowing the cotton swab material to be completely pushed into the transition cavity. The second pushing block moves horizontally within the transition cavity, its height being flush with the bottom of the bone strip bag inlet, allowing the cotton swab material to be completely pushed into the bag. Through the separate pushing block design, the pushing mechanism of the storage tank and the pushing mechanism of the bone strip bag form independent height adaptation mechanisms, solving the problem of discontinuous pushing paths caused by height differences.

[0033] The above embodiments improve the adaptability of the equipment and enhance bagging efficiency and quality.
