Description

Technical Field

[0001] This utility model relates to the technical field of fragrance product production and processing equipment, and in particular to an automatic capping machine for mushroom-shaped fragrance packaging. Background Technology

[0002] Solid fragrances have seen a continuous increase in market demand due to their portability and long-lasting effects. Their packaging typically consists of two parts: a cup body and a mushroom-shaped cap. The cup body has a retaining rod inside, and the internal cavity is used to fill the fragrance paste. After filling, the mushroom cap must be precisely pressed against the cup body to achieve a seal, ensuring the fragrance paste does not easily evaporate or become contaminated. Therefore, the quality of the mushroom cap's sealing directly affects the product quality and lifespan of the solid fragrance.

[0003] Currently, the pressing process for solid fragrance mushroom caps in the industry generally adopts a manual operation mode. The specific process involves a coordinated operation of manual cap placement and manual cap pressing, typically requiring three operators to complete the pre-capping and final capping actions. The pressure applied manually relies entirely on the operator's experience for control, and the pressure value cannot be precisely maintained. Excessive pressure may cause deformation of the cup body, breakage of the mushroom cap, or misalignment of the mushroom cap with the internal fixing rod hole of the cup body, thus affecting the product's sealing performance and appearance integrity. Furthermore, during the manual cap placement stage, the angle and position of the mushroom cap are entirely determined by manual judgment, which can easily lead to the mushroom cap being crooked or misaligned. This requires additional adjustments in the subsequent pressing process, further reducing production efficiency. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the defects of the existing technology where the installation of mushroom caps is carried out manually, which easily leads to unstable pressing quality and low production efficiency.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0017] Reference Figures 1-6 As shown, this utility model discloses an automatic capping machine for mushroom-shaped fragrance packaging, comprising: The feeding assembly 1 includes a conveyor frame 11 and a vibratory feeder 12, wherein the vibratory feeder 12 is disposed on one side of the conveyor frame 11; The capping assembly 2 includes a support frame 21, a feeding mechanism 22, a pressing mechanism 23, and a positioning mechanism 24. The support frame 21 is mounted on the conveyor frame 11. The feeding mechanism 22 includes a mounting plate 221, a bidirectional clamping cylinder 222, and a feeding seat 223. The mounting plate 221 is mounted on the support frame 21 and is located on the top of the conveyor frame 11. The feeding seat 223 is mounted on the mounting plate 221 and faces the discharge port of the vibratory feeder 12. The bidirectional clamping cylinder 222 is mounted on the mounting plate 221. The telescopic ends of the bidirectional clamping cylinder 222 clamp the two sides of the feeding seat 223. The telescopic ends of the bidirectional clamping cylinder 222 are provided with a pair of baffles 224. A pair of baffles 224 pass through the feed seat 223; the pressing mechanism 23 includes a first cylinder 231, a contouring press head 232, and a suction nozzle 233. The first cylinder 231 is mounted on the support frame 21, the contouring press head 232 is mounted at the telescopic end of the first cylinder 231, and the suction nozzle 233 is mounted at the end of the contouring press head 232 near the feed seat 223; the first cylinder 231 drives the contouring press head 232 to pass through the feed seat 223; the positioning mechanism 24 includes a pair of positioning cylinders 241 and a positioning plate 242. The pair of positioning cylinders 241 are symmetrically arranged on both sides of the conveyor frame 11. The positioning cylinders 241 are connected to the support frame 21. The positioning plate 242 is mounted at the telescopic end of the positioning cylinders 241, and the positioning plate 242 is provided with a positioning notch 2421.

[0018] The vibrating plate 12 in the above structure can realize the batch automatic sorting of mushroom caps, organize the disordered mushroom caps into a uniform orientation and transport them to the discharge port. Excess misaligned mushroom caps can automatically fall and rearrange, preventing mushroom caps from getting stuck in the discharge track or groove. The conveyor frame 11 can be used to transport the cup body. The cup body filled with fragrance is transported on the conveyor frame 11, which saves manpower for feeding and ensures the stability of the feeding rhythm.

[0019] The feeding seat 223 in the feeding mechanism 22 faces the discharge port of the vibrating plate 12, which can accurately receive the mushroom caps and achieve initial positioning of the mushroom caps to prevent them from shifting or falling before entering the capping station. The bottom of the entire feeding seat 223 faces the conveyor frame 11. The product falls from the feeding seat 223 into the conveyor frame 11 and is pressed tightly against the cup body on the conveyor frame 11. Specifically, the bidirectional clamping cylinder 222 drives the baffles 224 on both sides to pass through the feeding seat 223 and seal the bottom of the feeding seat 223. After the mushroom caps enter the feeding seat 223, the mushroom heads are supported by the two baffles 224.

[0020] In the pressing mechanism 23, the contouring head 232 has a contouring groove on the side that fits against the product, allowing it to fully conform to the mushroom cap. The suction nozzle 233 inside the contouring head 232 is connected to a vacuum generator. The suction nozzle 233 can use negative pressure to hold the mushroom cap inside the feed seat 223, performing secondary calibration of the mushroom cap's position to ensure its posture before pressing and prevent misalignment. The mushroom cap in the adsorption state can move synchronously with the contouring head 232. When the contouring head 232 descends vertically under the drive of the first cylinder 231, the suction force of the suction nozzle 233 prevents the mushroom cap from tilting or flipping during descent, ensuring precise alignment of the mushroom cap's hole with the internal fixing rod of the cup body.

[0021] A pair of positioning cylinders 241 are symmetrically arranged on both sides of the conveyor frame 11. When the cup body is conveyed to the bottom of the feed seat 223, the cylinders synchronously drive the positioning plates 242 to move towards each other, clamping and fixing the cup body from both sides. This solves the alignment difficulties caused by cup body shaking and provides a stable reference for aligning the mushroom cap with the cup body hole. The positioning notch 2421 on the positioning plate 242 is precisely adapted to the shape of the cup body. When clamped, the inner wall of the notch fits tightly against the cup body, further restricting the rotation of the cup body.

[0022] In this invention, the vibratory feeder 12 of the feeding assembly 1 can automatically sort mushroom caps in batches and avoid jamming, while the conveyor frame 11 stably conveys the cup body, significantly saving manpower and ensuring cycle time. The feeding seat 223 of the feeding mechanism 22 accurately receives the mushroom caps, and the bidirectional clamping cylinder 222 drives the baffle 224 to achieve initial positioning and support of the mushroom caps. The contour pressing head 232 fits perfectly with the mushroom caps, and with the help of negative pressure adsorption and precise force application by the cylinder, it prevents the mushroom caps from shifting or tilting, ensuring precise alignment with the holes in the cup body. The symmetrical positioning cylinder 241 and the positioning plate 242 with the positioning notch 2421 of the positioning mechanism 24 can stably clamp the cup body and limit its displacement and rotation, allowing the mushroom caps to be accurately pressed into the cup body. This invention replaces the traditional manual capping mode, reducing labor costs, eliminating safety hazards, improving capping accuracy and production efficiency, and ensuring product consistency.

[0023] Furthermore, the feeding mechanism 22 also includes an infrared sensor 225 and a reflector 226, which are disposed on both sides of the feeding seat 223.

[0024] Specifically, through the photoelectric sensing between the infrared sensor 225 and the reflector 226, it is possible to determine in real time whether there is a mushroom cap in the feed seat 223 and whether the mushroom cap has been delivered to the preset station. This avoids the subsequent processes being accidentally triggered due to the mushroom cap not being supplied, being supplied incorrectly, or not being fully in place. It accurately identifies the status of the cap supply and provides a reliable status judgment basis for the capping process.

[0025] Furthermore, the feeding mechanism 22 also includes a first proximity sensor 227, which is disposed on one side of the telescopic end of the bidirectional clamping cylinder 222, and the bidirectional clamping cylinder 222 extends to abut against the first proximity sensor 227.

[0026] Specifically, the first proximity sensor 227 sends a signal by contacting the telescopic end of the bidirectional clamping cylinder 222, which can detect in real time and accurately whether the cylinder is fully extended. This avoids the baffle 224 from not being fully closed or being overextended due to air pressure fluctuations, mechanical jamming, etc., and ensures that the clamping limit of the mushroom cap in the feed seat 223 achieves the preset effect, providing reliable status feedback for the stable support of the mushroom cap and subsequent alignment and pressing.

[0027] Furthermore, the feed seat 223 has a guide port 2231 on the side near the vibratory plate 12.

[0028] Specifically, the guide port 2231 can form a transition channel from the discharge port of the vibratory feeder 12 to the inside of the feed seat 223. Compared with the straight port design, it can adapt to the posture of the mushroom caps conveyed by the vibratory feeder 12, and guide the mushroom caps to smoothly enter the feed seat 223 along the inclined or widened structure of the guide port 2231. This avoids jamming and collision problems caused by the deviation between the conveying direction of the mushroom caps and the inlet angle of the feed seat 223, and further improves the smoothness of the flow of mushroom caps from the vibratory feeder 12 to the feed seat 223.

[0029] Furthermore, the pressing mechanism 23 also includes a second cylinder 234, which is disposed between the first cylinder 231 and the contour pressing head 232.

[0030] Specifically, the second cylinder 234 is positioned between the first cylinder 231 and the contouring head 232 to achieve two-stage extension, separating the adsorption positioning and final pressing into two independent actions. The second cylinder 234 first extends with a small stroke, driving the suction nozzle 233 to precisely adhere to the surface of the mushroom cap and complete negative pressure adsorption. The second cylinder 234 focuses on precise adhesion and positioning during the adsorption stage, while the first cylinder 231 focuses on stable force application during the pressing stage. Each performs its own function, avoiding problems such as weak adsorption or over-pressing caused by conflicting pressure adjustments when a single cylinder simultaneously undertakes positioning and force application functions.

[0031] Furthermore, a fixing plate 235 is provided between the first cylinder 231 and the support frame 21, and a guide rail 236 is provided on the fixing plate 235. The axial direction of the guide rail 236 is arranged along the extension and retraction direction of the first cylinder 231, and the second cylinder 234 is slidably connected to the guide rail 236.

[0032] Specifically, the guide rail 236 is set along the extension and retraction direction of the first cylinder 231. Through sliding cooperation with the second cylinder 234, the second cylinder 234 is forced to reciprocate only in the vertical direction, avoiding the offset or tilt of the second cylinder 234 due to air pressure fluctuations, assembly gaps of the mechanism, etc., ensuring that the suction nozzle 233 always fits the mushroom cap in the vertical direction and the contoured pressure head 232 is pressed vertically, ensuring that the hole of the mushroom cap is coaxially aligned with the cup body fixing rod.

[0033] Furthermore, a pair of second proximity sensors 237 are provided on the fixed plate 235, and the pair of second proximity sensors 237 are arranged along the extension and retraction direction of the first cylinder 231. A limit rod 238 is also provided at the extension and retraction end of the first cylinder 231.

[0034] Furthermore, a pair of second proximity sensors 237 correspond to the maximum extension position and the initial retraction position of the first cylinder 231, respectively. Through the sensing cooperation between the limit rod 238 and the sensors, the upper and lower limits of the extension and retraction stroke of the first cylinder 231 can be precisely controlled to avoid excessive or shallow pressing due to air pressure fluctuations and load changes, ensuring uniform pressing depth for each batch of products and improving the stability of the sealing quality.

[0035] Furthermore, a third proximity sensor 239 is provided on one side of the second cylinder 234, and a limiting plate 2341 that cooperates with the third proximity sensor 239 is provided at the extension end of the second cylinder 234.

[0036] Specifically, when the second cylinder 234 extends, it drives the limiting plate 238 to abut against the third proximity sensor 239, which can accurately detect the extension and retraction status of the second cylinder 234, ensuring that the contact pressure and adsorption distance between the nozzle 233 and the mushroom cap are consistent, avoiding insufficient adsorption due to insufficient cylinder stroke, or excessive stroke causing the nozzle 233 to squeeze the mushroom cap.

[0037] Furthermore, referring to Figure 7 As shown, the capping assembly 2 also includes a material blocking mechanism 25, which includes a material blocking cylinder 251. The material blocking cylinder 251 is mounted on the support frame 21. The telescopic end of the material blocking cylinder 251 is arranged perpendicular to the axial direction of the conveying frame 11. The telescopic extension of the material blocking cylinder 251 is provided with a stop rod 252.

[0038] Specifically, when the cup body is conveyed to the capping station by the conveyor frame 11, the baffle 252 extends to precisely intercept the cup body. Combined with the bidirectional clamping of the positioning mechanism 24, it forms a dual positioning of front-end interception and side clamping, which completely restricts the front-back and left-right displacement of the cup body and avoids the cup body from deviating from the pressing center due to conveying inertia or assembly line vibration, thus providing a stable premise for the precise alignment of the mushroom cap and the hole in the cup body.

[0039] In summary, this utility model introduces an automatic mushroom capping machine for fragrance packaging. Its operation is as follows: a vibrating plate 12 automatically sorts a batch of disordered mushroom caps and conveys them to the feeding seat 223. A bidirectional clamping cylinder 222 drives a baffle 224 to support and position the mushroom caps. The cup body is conveyed to the capping station via a conveyor frame 11 and is clamped and fixed by a positioning plate 242 driven by a positioning cylinder 241. Subsequently, the contour pressing head 232 of the pressing mechanism 23 uses a suction nozzle 233 to adsorb the mushroom caps under negative pressure and perform secondary posture calibration. Finally, the first cylinder 231 drives the contour pressing head 232 to precisely press the mushroom caps into the cup body. This utility model replaces traditional manual operation, saving labor costs, eliminating safety hazards, and improving production efficiency. Furthermore, through multiple positioning and calibration mechanisms such as sorting, clamping, adsorption, and contour fitting, it solves problems such as alignment deviation and unstable pressing, ensuring capping accuracy, guaranteeing product consistency in mass production, reducing production losses, and adapting to the needs of large-scale mass production.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
