Description

Technical Field

[0001] The invention relates to the technical field of cosmetic tube production, and in particular to an automatic production line for cosmetic tubes. Background Art

[0002] In cosmetic packaging, such as lipstick, metal tubes or polymer tubes are often used for packaging. Polymer tubes are often made by split injection molding, and then the injection molded tube parts are welded together by an ultrasonic welding machine.

[0003] However, in reality, during the production process, companies need to separately injection mold each component. For example, for a lipstick tube, the plastic base and the tube body need to be separately injection molded, and then manually placed on an ultrasonic welding machine for welding by workers. This production method is inefficient. And because companies often divide injection molding and welding into different areas, combined welding requires workers to constantly move parts, which further results in slow production efficiency and a low degree of automation.

DETAILED DESCRIPTION

[0078] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0079] like Figure 1As shown, the present invention provides an automatic production line for cosmetic tubes, including a first injection molding mechanism 1, a second injection molding mechanism 2 and an assembly welding mechanism 3, wherein the first injection molding mechanism 1 is used for injection molding a plastic base, the second injection molding mechanism 2 is arranged in parallel with the first injection molding mechanism 1, and the second injection molding mechanism 2 is used for injection molding a plastic tube body, and the output ends of the first injection molding mechanism 1 and the second injection molding mechanism 2 are respectively oriented toward the assembly welding mechanism 3, and the assembly welding mechanism 3 is used for assembly welding the plastic base and the tube body. The present invention directly produces the plastic base and the plastic tube body from the injection molding machine 10 through the first injection molding mechanism 1 and the second injection molding mechanism 2, and then welds them through the assembly welding mechanism, thereby reducing manual operation links, and the product is fully automated from injection molding to assembly welding, which can optimize the production layout and improve production efficiency.

[0080] like Figure 2 As shown, the first injection molding mechanism 1 includes an injection molding machine 10, a conveyor 11, a cooling device 12, a material distribution device 13 and a clamping device 14. The injection molding machine 10 is used to produce plastic bases by injection molding. The conveyor 11 is arranged in parallel with the injection molding machine 10. The conveyor 11 is used to transport the plastic base. The cooling device 12 is arranged on the conveyor 11. The cooling device 12 is used to cool the plastic base. The material distribution device 13 is arranged on the conveyor 11. The material distribution device 13 is arranged adjacent to the cooling device 12. The material distribution device 13 is used to separate multiple plastic bases at intervals. The clamping device 14 is arranged in parallel with the conveyor 11. The clamping device 14 is used to clamp the plastic base on the conveyor 11 and transport it to the assembly welding mechanism 3. The present application realizes the automation of the production process by automatically injecting and producing the plastic base through the injection molding machine 10, and the automatic transport of the conveyor 11, and the automatic clamping and transport of the clamping device 14, which greatly reduces manual operations and improves production efficiency. The cooling device 12 ensures that the plastic base is cooled in time during the conveying process, making its quality more stable, and the material dividing device 13 can accurately space the plastic base, ensuring the accuracy of subsequent assembly and welding, thereby improving the overall quality of the product. In addition, the injection molding machine 10, the conveyor 11, the cooling device 12, the material dividing device 13 and the clamping and moving device 14 are reasonably combined and arranged to form a set of efficient production processes, thereby improving production efficiency and product quality.

[0081] The cooling device 12 is a plurality of cooling fan assemblies arranged on the conveyor 11, which cools the plastic parts just injected by air cooling to accelerate the temperature reduction and stability.

[0082] Specifically, the structure of the second injection molding mechanism 2 is the same as that of the first injection molding mechanism 1 and is symmetrically arranged with the first injection molding mechanism 1 .

[0083] Specifically, Figure 3As shown, the assembly welding mechanism 3 includes a turntable 30, and a first feeding structure 31, a dust removal structure 32, a second feeding structure 33, a first ultrasonic welding structure 34, a second ultrasonic welding structure 35, an airtight detection structure 36, a defective output manipulator 37 and a finished product output manipulator 38 arranged around the turntable 30 in sequence. The first feeding structure 31 is connected to the first injection molding mechanism 1, and the second feeding structure 33 is connected to the second injection molding mechanism 2. A plurality of fixed molds 301 are provided on the turntable 30. The present invention drives each station to operate in sequence through the rotation of the turntable 30, realizes continuous production, reduces the intermediate waiting time, and multiple structures work together to improve the efficiency of assembly welding. At the same time, the dust removal structure 32 can effectively remove impurities and ensure the welding quality; the airtight detection structure 36 detects the airtightness and welding effect of the product to improve the product quality. In addition, the assembly welding mechanism 3 is provided with a secondary ultrasonic welding method, which can reduce the welding difficulty and increase the welding speed. At the same time, the interface of the plastic parts after secondary welding is more stable and smooth, which is conducive to improving the product quality.

[0084] The first feeding structure 31 and the second feeding structure 33 have the same structure, and the first ultrasonic welding structure 34 and the second ultrasonic welding structure 35 are prior arts, which will not be described in detail in this application.

[0085] In one embodiment, the dust removal structure 32 includes a dust removal lifting cylinder, a pressure block and a dust removal air pipe. The dust removal lifting cylinder is arranged above the fixed mold 301 through a bracket. The dust removal lifting cylinder drives the pressure block and the dust removal air pipe to move up and down. The pressure block presses the plastic base to prevent it from being blown or even blown away by the airflow during dust removal, and the dust removal air pipe will output airflow to blow the plastic base to blow away the dust particles on its surface to avoid adverse effects on subsequent welding.

[0086] In one embodiment, the airtight detection structure 36 includes an airtight lifting cylinder, a sealed air pipe and an air pressure detector. The airtight lifting cylinder is fixed above the fixed mold 301 by a bracket, and the airtight lifting cylinder drives the sealed air pipe to move up and down. Since the bottom of the plastic part is in a closed state after welding, the sealed air pipe will extend into the upper opening of the plastic part after it descends. By detecting the air pressure change of the corresponding sealed air pipe after ventilation by the air pressure detector, it can be known whether the corresponding plastic part is welded intact. For defective products in welding, they can be taken out by the defective output manipulator 37 of the next process, placed in a defective product placement container or a defective product conveyor (not shown in the figure), and processed uniformly. Plastic parts that are good products after welding will enter the next process, be taken out by the finished product output manipulator 38, and placed in a finished product placement container or a defective product conveyor (not shown in the figure).

[0087] like Figure 4As shown, the clamping and moving device 14 includes a support frame 141, a clamping jaw member 142, a material discharge platform member 143 and a material moving member 144. The support frame 141 is arranged in parallel with the conveyor 11. The bottom of the clamping jaw member 142 is fixedly connected to the support frame 141 and the conveyor 11 respectively. The material discharge platform member 143 is fixed on the support frame 141. The clamping jaw member 142 is used to grab the plastic base from the conveyor 11 and place it on the material discharge platform member 143. The material moving member 144 is fixed on the support frame 141 and is above the material discharge platform member 143 and the first loading structure 31. The material moving member 144 is used to grab the plastic base from the material discharge platform member 143 and place it on the first loading structure 31. The clamping claw member 142 can quickly grab the plastic base, and the material moving member 144 can quickly transfer it to the first feeding structure 31. The entire process is automated, reducing manual operation time and improving production efficiency; precise clamping and placement actions can reduce material damage and waste and reduce production costs.

[0088] like Figure 5 As shown, the first loading structure 31 includes a loading rack 311, a track plate 312, an adjusting member 313, a clamping member 314 and a clamping robot 315. The track plate 312 is fixed on the loading rack 311. The clamping member 314 is slidably connected to the track plate 312. The clamping member 314 is located below the material moving member 144. The clamping member 314 is used to clamp the plastic base. The adjusting member 313 is fixedly connected to the loading rack 311, and the adjusting member 313 is connected to the clamping member 314. The adjusting member 313 drives the clamping member 314 to slide. The clamping robot 315 is arranged adjacent to the fixed mold 301. The clamping robot 315 is used to grab the plastic base from the clamping member 314 and place it on the fixed mold 301. The present invention ensures a stable working platform by the fixed connection between the loading rack 311 and the track plate 312, and the sliding connection between the clamping member 314 and the track plate 312, combined with the precise driving of the adjusting member 313, realizes the efficient and precise clamping and movement of the plastic base. This process reduces manual operation, avoids production delays and product defects caused by improper manual operation, and thus improves production efficiency. At the same time, automated operation reduces the idle time of the equipment and improves production efficiency. The linkage design of the adjusting member 313 and the clamping member 314 ensures the smooth sliding of the clamping member 314 on the track 3121, and the precise matching of the clamping manipulator 315 and the fixed mold 301 makes the entire loading process both efficient and stable, and easy to operate and maintain.

[0089] like Figure 6As shown, the first injection molding mechanism 1 also includes a screening device 15 and a material blocking device 16. The screening device 15 and the material blocking device 16 are respectively arranged on the conveyor 11. The conveyor 11 is sequentially provided with a cooling device 12, a material dividing device 13, a screening device 15 and a material blocking device 16 along the forward conveying direction. The clamping claw member 142 is located above the material blocking device 16. The screening device 15 is used to screen the plastic base, and the material blocking device 16 is used to intercept / avoid the plastic base. The present application automatically removes unqualified plastic bases by adding a screening device 15 to ensure that only products with qualified quality enter the subsequent process, effectively avoiding manual re-inspection, saving time, and thus greatly improving production efficiency; and high-precision screening ensures that each plastic base meets the standard, improves the uniformity and reliability of the product, and thus enhances the quality of the final product. In addition, the coordinated work of the screening device 15 and the material blocking device 16 is greatly beneficial to the reprocessing or discarding of defective products, significantly reduces the loss of raw materials, and indirectly reduces production costs.

[0090] Specifically, Figure 7 As shown, the screening device 15 includes a screening bracket 151, an L-shaped adjustment seat 152 and a screening detector 153. The screening bracket 151 is fixedly connected to the conveyor 11, the L-shaped adjustment seat 152 is adjustably connected to the screening bracket 151, the screening detector 153 is fixedly connected to the L-shaped adjustment seat 152, and the screening detector 153 faces the conveyor 11. The screening detector 153 is used to detect the shape of the plastic base.

[0091] like Figure 8As shown, the material blocking device 16 includes a material blocking fixed seat 161, a material blocking driving cylinder 162, an adjusting rack 163, an adjusting gear 164, a bearing seat 165, an adjusting rod 166 and a material blocking member 167. The material blocking fixed seat 161 is fixedly connected to the conveyor 11, the material blocking driving cylinder 162 is fixedly connected to the material blocking fixed seat 161 and the output end is fixedly connected to the adjusting rack 163, the bearing seat 165 is fixed on the material blocking fixed seat 161, the adjusting rod 166 passes through the bearing seat 165, one end of the adjusting rod 166 is fixedly connected to the adjusting gear 164, the adjusting gear 164 is meshed with the adjusting rack 163, the material blocking member 167 is fixedly connected to the adjusting rod 166, and an intercepting ring 1671 is provided on the material blocking member 167, the material blocking member 167 is on the conveyor 11 and the intercepting ring 1671 faces the conveyor 11, and the intercepting ring 1671 is used to intercept the plastic base. When the screening detector 153 detects that there are defective plastic bases, it will give a signal. After receiving the signal from the screening detector 153, the blocking device 16 drives the blocking drive cylinder 162 to operate, drives the adjustment rack 163 to drive the adjustment gear 164 to rotate, and makes the blocking member 167 rotate, so that the interception ring 1671 moves upward, thereby avoiding the conveyor 11. When there is no interception ring 1671 to block the defective plastic base, it will move forward with the operation of the conveyor 11 until it falls into the recycling container (not shown) placed at the end of the conveyor 11 in advance, waiting for unified recycling.

[0092] The screening device 15 is adjustable through the L-shaped adjustment seat 152 and the screening bracket 151, and cooperates with the fine adjustment mechanism in the material blocking device 16, so that it can be fine-tuned according to the product size and production requirements, ensuring that the system can operate efficiently and stably under different working conditions, and realizing the flexibility and adaptability of the device. In the material blocking device 16, the precise control of the material blocking drive cylinder 162 and the efficient cooperation of the adjustment rack 163 and the adjustment gear 164 not only realize the rapid response of the material blocking member 167, but also significantly outperform similar solutions in terms of energy consumption, showing the high efficiency and energy-saving characteristics of the device. In addition, the modular design of each component of the present invention makes the production line more convenient during maintenance and upgrading, reduces maintenance costs, and also shortens the downtime of the equipment and improves the overall efficiency of the equipment.

[0093] In one embodiment, a crushing and recovery device is provided at the end of the conveyor 11, which can be used to immediately crush the defective plastic base and convey the crushed material to the injection molding machine 10 for re-injection molding, thereby reducing the loss of product raw materials, reducing manual operations, and improving the intelligent level of the setting.

[0094] like Fig. 9As shown, the material distribution device 13 includes a material distribution seat 131, a material distribution worm 132, a material distribution fan 133, a material distribution motor 134 and a material distribution turbine 135.

The material distribution device 13 realizes the automatic and uniform distribution of the plastic base, which can improve production efficiency. The semicircular design and symmetrical layout of the material distribution blades 133 ensure a smooth transition of the product during the conveying process. At the same time, the material distribution motor 134 drives the material distribution worm 132 to drive the material distribution blades 133 to rotate, thereby accurately controlling the distribution rate of the product.

[0095] In addition, the material distribution device 13 can ensure that only one plastic base passes through each time, which can make the screening detector 153 more accurate and reduce errors. And by adjusting the rotation rate of the material distribution motor 134, the transmission of the plastic base on the conveyor 11 can be controlled, reducing the collision between products, and also facilitating the cooling effect of the cooling device 12 on it. At the same time, since the material distribution device 13 allows only one plastic base to pass through each time, when the screening detector 153 detects that the base passing through at this time is unqualified, the material blocking device 16 can directly avoid it and allow it to enter the recycling, realizing the linkage of multiple devices, facilitating production recycling, and also ensuring the quality of the components to be welded later, and improving the yield rate.

[0096] like Figure 10-11 As shown, the clamping jaw assembly 142 includes a clamping jaw fixing seat 1421, a clamping jaw driving device 1422, a double-acting cylinder 1423 and a clamping jaw 1424. The clamping jaw fixing seat 1421 is respectively fixedly connected to the support frame 141 and the conveyor 11, the clamping jaw driving device 1422 is arranged on the clamping jaw fixing seat 1421, the output end of the clamping jaw fixing seat 1421 is fixedly connected to the double-acting cylinder 1423, the clamping jaw 1424 is respectively fixedly connected to the two ends of the double-acting cylinder 1423, the clamping jaw driving device 1422 is used to drive the clamping jaw 1424 to reciprocate between the conveyor 11 and the discharge table assembly 143, and the clamping jaw 1424 is used to grasp / release the plastic bottom.

[0097] The unloading table component 143 includes a slide 1431, a slide rail 1432, a slide drive motor 1433 and a multi-position placement seat 1434. The slide rail 1432 is on the support frame 141.

A plurality of placement positions are provided on the multi-position placement seat 1434. The multi-position placement seat 1434 is used to place a plastic base.

[0098] The present invention greatly improves the handling efficiency of the plastic base through the coordinated operation of the automated clamping claw component 142 and the material discharging platform component 143. The precise design of the clamping claw component 142 enables the clamping claw 1424 to accurately grasp and release the plastic base without manual intervention, which significantly speeds up the material flow; the multi-position placement seat 1434 on the material discharging platform component 143 allows multiple products to be on standby at the same time, reducing waiting time and improving the overall throughput capacity of the assembly line.

[0099] The present clamping jaw assembly 142 moves the clamping jaw 1424 to the top of the conveyor 11, and clamps the qualified plastic base that meets the specifications, and then moves the clamping jaw 1424 to the top of the multi-position placement seat 1434 through the clamping jaw driving device 1422, and places the qualified plastic base on the multi-position placement seat 1434. The multi-position placement seat 1434 is provided with a detector (not shown in the figure). When the plastic base is placed on the first hole position of the multi-position placement seat 1434, the slide drive motor 1433 runs and drives the slide 1431 to slide, so that the second hole position moves to the bottom of the corresponding clamping jaw 1424, so as to facilitate the placement of the next plastic base. In addition, the present clamping jaw assembly 142 utilizes the double-acting cylinder 1423 in combination with the clamping jaw driving device 1422 to achieve precise control and high-speed response of the clamping jaw 1424, which provides stronger adaptability and control accuracy compared to the traditional single cylinder. The combination of the slide drive motor 1433 and the slide rail 1432 enables the unloading platform component 143 to move freely in space, thereby enhancing the flexibility and scalability of the production line and meeting the production needs of different types and scales. At the same time, the present invention uses a modular design to make each component independent and easy to replace, thereby reducing the complexity of daily maintenance, shortening the fault recovery time, and ensuring the continuous and efficient operation of the production line.

After the material transfer clamping jaw assembly 1449 clamps the plastic base, the second sliding cylinder 1446 operates to move the movable slider 1444 to reset. When the material transfer clamp assembly 1449 clamps the plastic base and the second sliding cylinder 1446 is reset, the third slide module 1448 operates to drive the material transfer clamp assembly 1449 to move above the clamping member 314, and place the plastic base on the clamping member 314. The present invention integrates a multi-axis pneumatic control unit to form a three-dimensional positioning and handling system, breaking through the traditional limitation of unidirectional linear motion and showing a high degree of flexibility and precision.The introduction of the automated material handling system replaces the previous manual handling process, reducing labor costs; and the use of efficient pneumatic components and precise position control strategies reduces product damage and repeated processes caused by manual operation, further saving raw material consumption and energy costs.

[0101] In addition, the step-by-step driving mode of the first pneumatic module 1441, the second sliding cylinder 1446 and the third slide module 1448 not only simplifies the control system, but also makes the layout of the equipment more compact and widely applicable, and can adapt to the material handling needs in various production environments.
