Description

Technical Field

[0001] This utility model relates to the technical field of mold cleaning, and specifically to a mold cleaning device. Background Technology

[0002] Against the backdrop of the booming beauty industry, lipstick, as a core product, directly impacts a company's competitiveness through its production quality and efficiency. In automated lipstick filling production, existing technologies face a significant challenge: occasionally, molten material drips onto the bottom of the mold tray or the conveyor belt during filling head transitions. These drips rapidly cool and solidify, triggering a series of chain reactions.

[0003] First, the condensate can easily clog the mold holes at the bottom of the mold tray, causing contaminants to seep upwards during subsequent filling and directly contaminate the surface of the lipstick tube, resulting in defective products. Second, the condensate can block the light path of the laser marking machine, causing the printing of characters such as product batch numbers and expiration dates to be blurry or missing, affecting information traceability and compliance.

[0004] Currently, the industry generally uses manual cleaning to address this issue, where operators scrape off the residue manually after the machine is stopped. This method has significant drawbacks: the cleaning effect depends on personal experience and is difficult to achieve thoroughly; frequent machine shutdowns interrupt continuous production, reducing efficiency; increased labor costs and safety risks; and hard tools may scratch precision molds.

[0005] It is evident that manual cleaning can no longer meet the demands of automated production. Developing technology that can automatically clean the mold base, achieving real-time and precise removal of contaminants and preventing dirt from contaminating the lipstick tube, has become an urgent need for the lipstick industry to improve quality and reduce costs.

[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0026] Please see Figure 1 The mold cleaning device provided in this application embodiment includes: a frame 1, a conveying assembly 2, a reciprocating assembly 3, and a cleaning head 4; The frame 1 is used to support the entire device; The conveying assembly 2 includes a first conveyor belt 21 and a second conveyor belt 22 that are perpendicular to each other and mounted on the frame 1. The first conveyor belt 21 and the second conveyor belt 22 each have an input end and an output end. The output end of the first conveyor belt 21 is connected to the input end of the second conveyor belt 22. The input end of the second conveyor belt 22 is provided with a receiving groove 221. The reciprocating component 3 is connected to the frame 1, the reciprocating component 3 is located at the output end of the first conveyor belt 21, and the reciprocating component 3 moves back and forth along the width direction of the first conveyor belt 21. The cleaning head 4 is mounted on the frame 1 and is located in the receiving groove 221. The cleaning head 4 is used to clean contaminants from the bottom of the mold 9.

[0027] In this embodiment, when the mold 9 on the first conveyor belt 21 is transported to its output end, the mold 9 is pushed towards the input end of the second conveyor belt 22 by the reciprocating assembly 3. During the movement of the mold 9, the cleaning head 4 located in the receiving groove 221 cleans the bottom of the mold 9. The cleaned mold 9 continues to be transported to the second conveyor belt 22. This cleaning device can quickly clean the contaminants adhering to the bottom of the mold 9, achieving a higher level of cleanliness than manual cleaning. Moreover, the entire process requires no manual operation, is fast and efficient, and does not require machine downtime.

[0028] Please see Figure 2 In some embodiments, the cleaning head 4 includes a brush 41 and a motor 42, which are respectively mounted on the frame 1. The brush 41 extends along the width of the second conveyor belt 22, and the motor 42 drives the brush 41 to rotate. The bottom of the lipstick mold 9 typically has grooves, gaps, positioning holes, and other structures. The bristles of the brush 41 have flexible deformation capabilities, allowing them to penetrate these narrow spaces and conform to the uneven surfaces of the bottom of the mold 9, sweeping away adhering dust, debris, residue, and other contaminants. Compared to hard scrapers, vacuum cleaners, and other tools, this avoids cleaning blind spots caused by structural obstructions. Simultaneously, the flexible bristles of the brush 41 will not scratch the surface of the mold 9, nor will they cause scratches or wear. This effectively maintains the dimensional accuracy and surface finish of the mold 9, preventing damage to the mold 9 due to overly hard cleaning tools and extending the service life of the mold 9.

[0029] It is worth noting that by selecting bristles of different hardness and adjusting the rotation or movement speed of the brush 41, the applicability of the device can be improved to accommodate different types of contaminants or different types of molds 9.

[0030] When the brush 41 cleans the bottom of the mold 9, dust, debris, and other contaminants are easily stirred up or fall onto the surface of the mold 9 and into the gaps between the equipment, causing secondary pollution. Therefore, in some embodiments, the mold 9 cleaning device further includes an adsorption component 5, which is located below the cleaning head 4 and connected to the frame 1. The adsorption component 5 is used to absorb the contaminants cleaned by the cleaning head 4. The adsorption component 5 can suck up the contaminants the moment they leave the mold 9, preventing them from re-adhering to the mold 9 or entering the equipment from the source, thus ensuring the cleanliness of the mold 9 surface after cleaning. At the same time, the vacuum generator 53 is small in size, lightweight, and low in energy consumption. Its overall structure, combined with the adsorption chamber 51 and vacuum tube 52, is compact and does not require much installation space. It can be easily and rigidly connected to the frame 1 without increasing the load on the frame 1, ensuring the stability of the equipment during operation.

[0031] Please see Figure 3In some embodiments, the adsorption assembly 5 includes an adsorption chamber 51, a vacuum tube 52, and a vacuum generator 53. The vacuum generator 53 is connected to the frame 1, and the vacuum tube 52 connects the adsorption chamber and the vacuum generator 53. The adsorption chamber 51 is located below the cleaning head 4. The vacuum generator 53 is driven by compressed air and produces no oil mist during operation, preventing oil from entering the adsorption chamber 51 through the vacuum tube 52 and contaminating the collected pollutants. It also prevents oil leakage from contaminating the surface of the mold 9, affecting the precision of the mold 9 and the quality of subsequent products. The collected pollutants can be directly and centrally treated, reducing secondary pollution.

[0032] It is worth noting that, to prevent contaminants from adhering to the inner wall of the adsorption chamber 51 or the inner wall of the vacuum tube 52 over a long period of time, thus adversely affecting the adsorption effect, this application preferably installs a filter screen inside the adsorption chamber 51 to avoid the above situation. When cleaning the adsorption chamber 51, only the filter screen needs to be replaced.

[0033] In some embodiments, the reciprocating assembly 3 includes an electric push rod 31 and a push plate 32. The electric push rod 31 is mounted on the frame 1, and the push plate 32 is driven to the power output end of the electric push rod 31. The electric push rod 31 drives the push plate 32 to reciprocate along the width direction of the first conveyor belt 21. The electric push rod 31 is driven by a lead screw via a motor 42, providing a stable output thrust and controllable stroke. It can precisely drive the push plate 32 to reciprocate at a uniform speed along the width direction of the first conveyor belt 21, achieving millimeter-level displacement positioning. Furthermore, the electric push rod 31 is compact and can be directly fixed on the frame 1 without the need for additional air sources, hydraulic stations, or other auxiliary devices. The overall structure is simple and does not occupy too much space on both sides of the conveyor belt. At the same time, the push plate 32 is directly driven by the power output end, reducing complex linkage mechanisms and lowering the probability of equipment failure.

[0034] It is worth noting that a cylinder can also be used instead of the electric push rod 31. Specifically, the push plate 32 is fixedly mounted on the power output end of the cylinder, and the cylinder is positioned at the output end of the first conveyor belt 21, with the cylinder located on the side of the first conveyor belt 21 away from the cleaning head 4, and the power output end of the cylinder facing the cleaning head 4. With this configuration, the extension and retraction of the cylinder can drive the push plate 32 to move closer to / away from the cleaning head 4, thereby pushing the mold 9 to the cleaning head 4.

[0035] During the pushing process, the pusher plate 32 may be subjected to the reaction force of the mold 9 or the lateral force generated by contact with foreign objects. When these forces act directly on the power output end of the electric push rod 31, they can easily cause the push rod lead screw to bend and the motor 42 to be overloaded. Therefore, in some embodiments, the reciprocating assembly 3 further includes a guide rod 33, which is disposed on the frame 1 and is arranged along the movement path of the electric push rod 31. The pusher plate 32 is slidably disposed on the guide rod 33. When the electric push rod 31 drives the pusher plate 32 to move back and forth, if it relies solely on its own support, it is prone to slight radial sway under long-term stress, causing the movement trajectory of the pusher plate 32 along the width direction of the conveyor belt to deviate from the preset path. The guide rod 33 and the pusher plate 32 slide together to forcibly constrain the movement direction of the pusher plate 32, ensuring that the pusher plate 32 always moves back and forth in a straight line, and avoiding inaccurate pushing position of the mold 9 due to deviation. In addition, when pushing the mold 9, the guide rod 33 can bear most of the lateral force, disperse the pressure on the electric push rod 31, and extend the service life of the push rod.

[0036] In some embodiments, the mold 9 cleaning device further includes a sensor 6, which is located at the output end of the first conveyor belt 21 and is used to detect whether there is a mold 9 at the output end of the first conveyor belt 21. In some embodiments, the mold 9 cleaning device further includes a controller 8, which is electrically connected to the reciprocating assembly 3, the cleaning head 4, and the sensor 6. The sensor 6 can detect in real time whether the mold 9 has reached the output end of the conveyor belt. The detection signal can be directly transmitted to the controller 8, which controls the reciprocating assembly 3 to start pushing the mold 9 to the cleaning head 4, and then controls the cleaning head 4 to start cleaning the mold 9. This eliminates the need for manual judgment and operation, reduces human error, avoids energy consumption due to equipment idling, reduces the operating cost of the production line, and further adapts to the continuous operation requirements of automated production lines.

[0037] During the conveyor belt transport process, the mold 9 is prone to lateral movement due to conveyor belt vibration and speed fluctuations, resulting in misalignment between the bottom of the mold 9 and the cleaning head 4, creating a cleaning blind zone. Therefore, in some embodiments, the mold 9 cleaning device further includes an anti-movement component 7, which is located at the input end of the second conveyor belt 22. The anti-movement component 7 is arranged along the width direction of the second conveyor belt 22 and is positioned above the cleaning head 4. The anti-movement component 7 is used to block the mold 9 that moves above the cleaning head 4, preventing the mold 9 from deviating from the predetermined path.

[0038] In this embodiment, if the mold 9 moves too much during the cleaning operation, it may fall off the edge of the conveyor belt, causing damage and reduced precision. The anti-movement component 7 effectively prevents the mold 9 from shifting and falling, reducing the risk of equipment failure and mold 9 scrap. Furthermore, the anti-movement component 7 can limit the mold 9 in the width direction, forcing the mold 9 to pass over the cleaning head 4 along a predetermined path, ensuring that the cleaning head 4 can evenly cover the area to be cleaned at the bottom of the mold 9, improving the consistency of the cleaning effect.

[0039] If a fixed baffle is used for limiting movement, the mold 9 will experience hard sliding friction with the baffle during conveying, which can easily cause scratches on the side wall of the mold 9 and wear and deformation of the baffle, affecting the accuracy and limiting effect of the mold 9. Therefore, in some embodiments, the anti-slip component 7 includes: a rotating shaft 71 and a rotating drum 72. The rotating shaft 71 is arranged along the width direction of the second conveyor belt 22 and is fixedly connected to the frame 1. The rotating drum 72 is rotatably mounted on the rotating shaft 71. The rotating drum 72 can rotate freely around the fixed rotating shaft 71. When the mold 9 contacts the rotating drum 72, it will drive the rotating drum 72 to rotate synchronously, greatly reducing frictional resistance, avoiding damage to the surface of the mold 9, and extending the service life of the anti-slip component 7.

[0040] In summary, the mold cleaning device provided in this embodiment allows for the rapid removal of contaminants adhering to the bottom of the mold 9 when it is conveyed to its output end on the first conveyor belt 21. The mold 9 is then pushed towards the input end of the second conveyor belt 22 by the reciprocating assembly 3. During the movement of the mold 9, a cleaning head 4 located in the receiving groove 221 cleans the bottom of the mold 9. The cleaned mold 9 is then conveyed back to the second conveyor belt 22. This cleaning device can quickly remove contaminants from the bottom of the mold 9, achieving a higher level of cleanliness compared to manual labor. Furthermore, the entire process requires no manual operation, is fast and efficient, and eliminates the need for machine downtime.
