During the capping process, the reciprocating sliding of the sliding feeding assembly is used to adjust the alignment of each group of the bottom support parts and the lifting and pressing assembly.

[0007] When a part of the base portion is located opposite to the lifting and pressing assembly, the product body and its corresponding cover body are pressed by the lifting and pressing assembly, and the remaining part of the base portion is used for unloading and / or loading.

[0008] In some embodiments, the sliding feeding assembly includes a bottom plate and a first driving member, wherein the first driving member is connected to the bottom plate and is used to drive the bottom plate to slide back and forth relative to the lifting and pressing assembly;

[0009] The bottom supporting parts are all arranged on the bottom plate, so that they can be driven by the bottom plate to generate displacement.

[0010] In some embodiments, the sliding feeding assembly further includes a guide structure, and the guide structure and the bottom plate are cooperatively arranged to guide the sliding of the bottom plate to prevent the bottom plate from deviating during the sliding process.

[0011] In some embodiments, the lifting and pressing assembly includes a capping head and a second driving member, the second driving member is disposed on the base frame, and the output end of the second driving member is connected to the capping head to drive the capping head to reciprocate in the vertical direction;

[0012] The end face profile of the capping head is adapted to the top profile of the cap body, and the bottom support portion has an open accommodating cavity, and the profile of the accommodating cavity is adapted to the bottom profile of the corresponding product body.

[0013] In some embodiments, the bottom bracket includes a support plate, a positioning plate and a base, which are used to jointly enclose and form the accommodating cavity;

[0014] The positioning plate and the base are both provided with slot structures adapted to the contour of the product body.

[0037] With the improvement of residents' consumption level, the production demand of large-capacity daily chemical products has gradually increased, which not only puts higher requirements on product quality, but also poses challenges to production efficiency and safety. In commercial mass production, achieving safe, efficient and stable automated production has become a difficult problem to be solved urgently. At present, in the production process of large-capacity special-shaped bottle products, the bottom of the bottle body is mostly curved, with a large volume, and the lid and the bottle body are sealed by snap-fit. In order to ensure the reliability of the seal, a large downward force needs to be generated instantly to complete the connection.

[0038] The existing production process mainly relies on manual operation. The operator needs to hold the bottle with one hand to keep the product upright, and use a rubber hammer to hammer the lid to complete the capping action. This production method has many shortcomings: low efficiency, unable to meet the growing market demand; high defective product rate, affecting product quality and corporate reputation; high labor intensity, causing a burden on the operator's body, and prone to occupational diseases in long-term repetitive labor. In addition, the inconsistency of manual operation also leads to the instability of product quality, increasing production costs and after-sales risks.

[0039] In view of the deficiencies of the prior art, in one embodiment, a capping device provided in the present application can effectively improve production efficiency and increase the automation of the capping process, thereby reducing labor costs and risks of manual operation.

[0040] Reference Manual Attached Figure 1 , Figure 2 The present application provides a capping device, which includes a base frame 2, a sliding feeding assembly 3 and a lifting and pressing assembly 4, which work together to optimize production efficiency and ensure product quality.

[0041] Specifically, Figure 4 As shown, the base frame 2 is provided with a sliding opening 20, which is used to adapt to the sliding requirements of the sliding feeding assembly 3, provide guidance and support for the sliding feeding assembly 3, and ensure its smooth and precise reciprocating motion. The sliding feeding assembly 3 includes at least two groups of bottom support parts 31, which are distributed along the sliding direction thereof, and the bottom support parts 31 are used to receive the product body, so that multiple products can be moved on the production line or the capping device at the same time, thereby improving the parallelism of the production process.

[0042] Among them, the lifting and pressing assembly 4 is the key part to realize the capping action. The lifting and pressing assembly 4 is arranged on the base frame 2 and is connected with the sliding opening 20. During the capping process, the reciprocating sliding of the sliding feeding assembly 3 is used to adjust the alignment of each group of the bottom support part 31 and the lifting and pressing assembly 4, so that the lifting and pressing assembly 4 can accurately dock with the product that needs to be pressed against the cover body. In other words, when the bottom support part 31 moves to the position corresponding to the lifting and pressing assembly 4, the lifting and pressing assembly 4 will apply the necessary pressure to make the cover body firmly pressed against the product body to complete the capping work.

[0043] At the same time, the other bottom support parts 31 that are not in the capping position can be used for unloading and / or loading operations, which not only ensures the continuity of the production process but also avoids idle time on the production line. In this way, the capping device in this embodiment can significantly improve the overall efficiency of the production line while ensuring the capping quality.

[0044] It should also be noted that the spacing and shape of the bottom support 31 can be adjusted according to production requirements to adapt to products of different sizes and shapes, thereby enhancing the versatility and flexibility of the capping device. On the other hand, when performing the capping operation, the product body can be placed on the bottom support 31 first, and then the cover body can be pre-installed on the product body; or the product body and the cover body can be pre-assembled and placed directly on the bottom support 31 as a whole, which not only improves the adaptability of the production line, but also allows the assembly process to be flexibly adjusted according to specific production requirements.

[0045] In this embodiment, there is no specific limitation on the type and setting form of the lifting and pressing component 4. For example, a servo motor is used as the driving force to provide a stable and repeatable capping force; and the cylinder provides a fast response capability to adapt to the fast-paced production environment. At the same time, the component has a certain flexibility. For example, through modular design, the relevant modules in the lifting and pressing component 4 can be quickly replaced to meet different capping requirements; or, the integrated intelligent pressure feedback system can adjust the pressure in real time to ensure the quality of the capping; or, in conjunction with the visual inspection system, the product position can be automatically detected to achieve accurate capping, further improving the level of automation.

[0046] On the other hand, the configuration of the sliding feeding assembly 3 is not specifically limited in this embodiment. The driving of the sliding feeding assembly 3 can be a servo motor to ensure precise control, or a pneumatic or hydraulic system to adapt to different load and speed requirements. In addition, through the integration of an intelligent control system, the moving speed and position of the assembly can be precisely adjusted, thereby working in conjunction with the lifting and pressing assembly 4 to achieve an efficient automated production process.

[0047] Preferably, the sliding feed assembly 3 can be designed with a sliding track (not shown in the drawings) to provide a stable guide to ensure its accuracy in reciprocating motion, especially in applications that require frequent movement and heavy loads. The sliding track design reduces the friction and wear of the sliding feed assembly 3 during movement, prolongs the service life of the equipment, and enhances the stability and repeatability of the entire feeding process by maintaining a constant contact point. In some embodiments, the design of the sliding track may include a locking mechanism to fix the sliding feed assembly 3 when necessary for easy maintenance and adjustment.

[0048] Based on the above embodiments, Figure 5 The sliding feeding assembly 3 includes a bottom plate 32 and a first driving member 33. The first driving member 33 is connected to the bottom plate 32, thereby driving the bottom plate 32 to slide back and forth relative to the lifting and pressing assembly 4. The bottom supporting part 31 in the above content is all arranged on the bottom plate 32. The bottom supporting part 31 can be driven by the bottom plate 32 to generate displacement so as to be accurately sent to the predetermined pressing position.

[0049] It can be understood that in this embodiment, the dynamic displacement of the base plate 32 is achieved by driving the first driving member 33, thereby driving the bottom support portion 31 and the products thereon to achieve automatic transportation, which significantly improves the automation level of the production line, reduces the time for manual handling and positioning, and also reduces product damage or positioning errors caused by improper manual operation.

[0050] Among them, the first driving member 33, as a key part of the sliding feeding assembly 3, has multiple options to achieve the reciprocating sliding of the bottom plate 32. For example, a servo motor can be selected as the driving source to achieve precise control of the position of the bottom plate 32 through a control system; or an electric push rod can be used to meet the dynamic requirements of the automated production line with its compact structure and fast response. These driving methods have their own advantages, such as the high precision of the servo motor and the compactness of the electric push rod, and they can be customized and optimized according to specific production environments and requirements.

[0051] In one embodiment, based on the above content, this embodiment uses a reciprocating cylinder as the first driving member 33 .

[0052] The reciprocating cylinder is widely used in the field of industrial automation due to its simple and reliable working principle and low maintenance cost. Through the linear motion of the reciprocating cylinder, the bottom plate 32 can efficiently drive the bottom support 31 and the product thereon to slide back and forth, thereby realizing a fast and accurate feeding process.

[0053] Furthermore, in some embodiments, the sliding feeding assembly 3 can also be triggered by a manual button signal, which can directly control the action of the reciprocating cylinder to achieve the reciprocating sliding of the bottom plate 32, simplifying the operation process, allowing the operator to intuitively control the production process, and improving the flexibility and response speed of production. Specifically, the reciprocating motion of the cylinder is triggered by a manually operated button, providing power for the bottom plate 32, so that it can drive the bottom support portion 31 and the product thereon to slide quickly and accurately to a predetermined position.

[0054] Moreover, the sliding feeding assembly 3 can also be provided with an intelligent control system of sensors and trigger switches. By setting a specific delay time, the system can automatically trigger the reverse movement of the reciprocating cylinder after the bottom plate 32 reaches a predetermined position, thereby realizing the automatic reciprocation of the bottom plate 32. The intelligent control strategy not only reduces the workload of the operator, but also improves the efficiency and fluency of the entire production process.

[0055] In one embodiment, the sliding feeding assembly 3 is provided with a guide structure, which is arranged in cooperation with the base plate 32 to ensure the stability and accuracy of the base plate 32 when it slides back and forth, and to provide precise guidance for the base plate 32 in the horizontal direction to prevent the base plate 32 from shifting or vibrating during high-frequency or long-distance sliding, thereby ensuring that the product on the bottom support portion 31 can be accurately delivered to the predetermined capping position.

[0056] The guide structure can be designed in a variety of different forms, such as linear guides, and can be customized according to the size and weight of the base plate 32 and the specific requirements of the production line. It can not only improve the smoothness of sliding and reduce the friction coefficient, but also significantly improve the durability and reliability of the entire component.

[0057] For details, please refer to the attached manual. Figure 1 The guide structure includes at least two guide bars 34, which are symmetrically distributed on both sides of the bottom plate 32 to form two parallel guide rails. The guide bars 34 on both sides are closely matched with the side edges of the bottom plate 32 to guide the bottom plate 32 to slide along a set straight path. The guide bars 34 are usually designed in a straight line shape to ensure the linearity of the bottom plate 32 during movement and reduce positioning errors caused by offset.

[0058] The use of the guide strips 34 significantly improves the stability of the bottom plate 32 during reciprocating motion. The guide strips 34 limit the lateral movement of the bottom plate 32, ensuring that the bottom plate 32 remains on the correct track during the entire sliding process. This guiding effect reduces the swing or deviation that may occur due to the sliding of the bottom plate 32, thereby improving the accuracy of the feeding process.

[0059] Without the guide strip 34, the bottom plate 32 may deviate during movement due to external factors (such as uneven load, uneven track, etc.), which may cause the product on the bottom support 31 to be unable to be accurately delivered to the lifting and pressing assembly 4 for capping, affecting production efficiency and product quality. The use of the guide strip 34 effectively solves this problem by providing a stable guide to ensure accurate sliding of the bottom plate 32, reduce positioning errors, and improve the reliability of the production process.

[0060] In another embodiment, if Figure 3 and Figure 4 The lifting and pressing assembly 4 in the above content includes a capping head 41 and a second driving member 42.

[0061] Among them, the second driving member 42 is fixed on the base frame 2, and its output end is connected to the capping head 41, which is responsible for driving the capping head 41 to perform accurate reciprocating motion in the vertical direction. Through automatic control, the uncertainty of human operation is reduced, ensuring that the force and position of each capping action can meet the preset standards.

[0062] It should be noted that, in this embodiment, the type of the second driving member 42 is similar to the type of the first driving member 33 , such as a reciprocating cylinder, and will not be described again here.

[0063] The end face profile of the capping head 41 is closely matched with the top profile of the cap body, which not only ensures the sealing during the capping process, but also avoids unnecessary damage to the product. This design effectively solves the problems of low efficiency, uneven capping and product damage commonly seen in traditional capping methods, and significantly improves production efficiency and product quality.

[0064] Optionally, the operator can monitor and adjust the capping force in real time by integrating a pressure sensor on the capping head 41 to ensure that each cap body can obtain uniform and appropriate pressure. In addition, the capping head 41 can be designed as a replaceable module to adapt to cap bodies of different shapes and sizes, thereby enhancing the versatility and flexibility of the equipment.

[0065] Furthermore, the base portion 31 has an open accommodating cavity 310, the contour of which matches the bottom contour of the product body to be capped, thereby ensuring that the position of the product body on the base portion 31 is relatively fixed, thereby reducing capping failure or damage to the product body due to product movement or deflection.

[0066] Before the capping operation begins, the product body is placed in the accommodating cavity 310 of the bottom support portion 31, and its bottom contour matches the internal shape of the accommodating cavity 310, thereby achieving stable support. At this time, the second driving member 42 of the lifting and pressing assembly 4 is started, driving the capping head 41 to move downward in the vertical direction until the end face of the capping head 41 contacts the top contour of the cover body. The end face design of the capping head 41 fully considers the shape of the cover body to ensure that the pressure can be evenly transmitted during the pressing process.

[0067] In one embodiment, the bottom bracket 31 includes a support plate 311 , a positioning plate 312 and a base 313 , which together form the aforementioned accommodation cavity 310 .

[0068] Among them, the positioning plate 312 and the base 313 are both provided with a slot structure adapted to the contour of the product body, the positioning plate 312 is fixed above the base 313, and the support plate 311 is fixed to the side wall of the positioning plate 312 for auxiliary support of the side wall of the product body.

[0069] Specifically, Figure 3 As shown, the positioning plate 312 is designed with a through hole, which is adapted to the peripheral wall contour of the product body, ensuring the vertical positioning of the product on the bottom support 31. The slot structure opened on the base 313 is designed for the bottom contour of the product body, and combined with the positioning plate 312, forms a stable support structure.

[0070] This embodiment uses the through holes on the positioning plate 312 and the slots on the base 313 to achieve dual adaptation to the peripheral wall and bottom contour of the product body, thereby ensuring the precise positioning of the product on the bottom bracket 31. The support plate 311 is fixed to the side wall of the positioning plate 312, which not only provides necessary auxiliary support for the product body, but also enhances the structural stability of the entire bottom bracket 31.

[0071] It should be noted that, in other embodiments, the support plate 311 can be designed to be adjustable to accommodate product bodies of different heights; the through holes on the positioning plate 312 can be designed as replaceable modules to adapt to product walls of different diameters and shapes.

[0072] In one embodiment, based on the above embodiment, the number of the bottom support parts 31 is two, and the two bottom support parts 31 are arranged at intervals along the sliding direction. The arrangement of the two bottom support parts 31 improves the operational flexibility, so that each bottom support part 31 can independently perform operations such as loading, capping or unloading. Therefore, while one bottom support part 31 is performing the capping operation, the other bottom support part 31 can be loading or unloading, thereby realizing the parallelization of the production process.

[0073] Furthermore, Figure 3As shown, a partition 5 is provided in the empty portion between the two bottom supporting portions 31, and both ends of the partition 5 are abutted against the support plates 311 of the two adjacent bottom supporting portions 31. Such a structural design not only ensures the independence between the bottom supporting portions 31, but also enhances the overall stability and rigidity through the partition 5, reduces the vibration or displacement that may occur during the automated operation, and ensures the accuracy of the capping operation.

[0074] In one embodiment, based on the above embodiment, two accommodating cavities 310 are provided on each bottom support portion 31, which are arranged side by side to provide accurate positioning and support for the product body to be capped. This design of double accommodating cavities 310 enables each bottom support portion 31 to process two products at the same time, thereby doubling the production capacity.

[0075] Correspondingly, the number of the capping heads 41 is also set to two to match the layout of the double accommodating chambers 310 on the bottom support portion 31. The two capping heads 41 are driven independently or synchronously by the second driving member 42, providing a flexible operation mode. The independent drive mode allows each capping head 41 to be controlled individually to meet the needs of different products or different capping requirements. The synchronous drive mode ensures that the two capping heads 41 perform capping in a coordinated manner, which is suitable for the same product or when synchronous capping operation is required.

[0076] By increasing the number of base parts 31 and capping heads 41, the side-by-side accommodating cavities 310 are combined with the corresponding driven capping heads 41 to achieve parallelization and flexibility of the production process, significantly improve the efficiency of the production line, and enable more products to be capped at the same time.

[0077] In one embodiment, Figure 1 As shown, the capping device includes a workbench 1, and the above-mentioned base frame 2 is arranged in the middle position of the workbench 1. This layout not only ensures the symmetry and balance of the device, but also optimizes the space utilization and provides conditions for the smooth operation of the sliding feeding component 3.

[0078] The sliding feeding assembly 3 is arranged along the length direction of the workbench 1, so that the base portion 31 can slide back and forth within the longitudinal range of the workbench 1. This design makes full use of the extended space of the workbench 1 and provides a wide operating platform for continuous conveying and capping of products.

[0079] On the basis of the above embodiment, the capping device is further provided with a limiting structure to limit the sliding of the sliding feeding assembly 3. Figure 2The two ends of the sliding feeding assembly 3 along the sliding direction are respectively provided with outwardly extending limit ends 61, which correspond to the limit posts 62 on the workbench 1. The number of limit posts 62 on the workbench 1 matches the number of limit ends 61 of the sliding feeding assembly 3, forming a precise positioning system.

[0080] Through the interaction between the limit end 61 and the limit column 62, the sliding position of the sliding feed component 3 on the workbench 1 is precisely controlled. When the sliding feed component 3 moves to the limit position or the preset position along its sliding direction, its limit end 61 will abut against the corresponding limit column 62, thereby preventing the component from sliding further. The design of the limit structure in this embodiment ensures that the sliding feed component 3 stops accurately in each reciprocating motion, and avoids operating errors or equipment damage caused by excessive sliding or position deviation. In addition, precise positioning also improves the repeatability and consistency of the entire capping process, further improving production efficiency and product quality.

[0081] It should be noted that the above embodiments can be freely combined as needed. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application, and these improvements and modifications should also be regarded as the protection scope of the present application.
