DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", and "connected" should be understood in a broad sense; for example, it can be a fixed connection, a detachable connection, or an integral connection, a mechanical connection, or an electrical connection, a direct connection, or an indirect connection through an intermediate medium, or the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The invention belongs to the field of liquid packaging machinery and is suitable for a rotary sealing device such as an integrated conventional PET cap and a special motion cap adapted to a PET bottle or a glass bottle.

[0026] See also Figure 1-4 A sealing integrated device of a moving cover and a conventional cover comprises a main transmission mechanism 1 and a rotary assembly 2. The rotary assembly 2 and the main transmission mechanism 1 are connected via a lifting device 6. By adjusting the screw of the lifting device 6, the rotary assembly 2 can be lifted and lowered on the axis of the main transmission mechanism 1, thereby adjusting the height of the whole machine and determining the best sealing effect.

[0027] The rotary assembly 2 is provided with a scale adjustment rod 11, and the scale adjustment rod 11 is provided with multiple groups, and the multiple groups of scale adjustment rods 11 are circumferentially arranged on the rotary assembly 2. Multiple groups of scale adjustment rods 11 ensure stability during adjustment, avoid errors, and increase safety. In this process, since both special sports covers and conventional covers need to be used, when changing the cover type, the height of the rotary assembly 2 needs to be adjusted according to the specific situation of the cover type. During the debugging process, when each corresponding cover type is adjusted to the optimal position, the scale adjustment rod 11 will have a scale of corresponding height, and the reading of the corresponding cover type will be recorded. When adjusting next time, there is no need to spend more time and energy for precise debugging, thereby greatly saving time and manpower. At the same time, when the sports cover and various conventional covers are changed, the specifications of each cover are different, and the design of the cam curve should be different. However, on the integrated machine, the cam is one of the main parts, and disassembly and change is a big project, which is undoubtedly not a technology possessed by the integrated design.

[0028] A differential motor 7 is provided on the rotary assembly 2, and the differential motor 7 is connected to the rotary support 5 through a gear set. A cam 12 is provided in the rotary assembly 2, and the cam 12 is connected to the transmission gear 10 through a gear. The rotary support 5 is driven by the differential motor 7, and the rotation speed of the transmission gear 10 is adjusted to compensate for the cam curve, thereby achieving the capping effect of the motion cover and various conventional covers.

[0029] The cam 12 is connected to the capping head 3, and a capping head capping mold 4 is provided at the bottom end of the capping head 3; during the entire rotation process, while the capping head 3 is rotating around the rotation center, the capping head 3, under the action of the transmission gear 10, follows the cam curve to rotate to complete the sealing action, and while the capping head 3 is revolving and rotating, the capping and screwing actions are completed by the capping head capping mold 4 on the capping head 3. Due to the particularity of the motion cap, the capping action cannot be achieved at the same capping point of the conventional cap. The capping head 3 is provided with multiple groups. The capping head 3 is movably connected to the inner wall of the connecting ring 13

[0030] The rotary component 2 is provided with a connecting ring 13, and a cap conveying component is fixedly provided on the connecting ring 13. The cap conveying component is the first cap conveying component 8 or the second cap conveying component 9. Therefore, two cap removal points are technically designed on the cam track. Therefore, the up and down stroke of the cam is different from the stroke of the conventional cam. In order to integrate the particularity of the motion cap, the up and down stroke of the cam is technically increased, and a cap removal point is added. Two sets of cap conveying components are configured, the first cap conveying component 8 and the second cap conveying component 9. The cap conveying component is fixed on the connecting ring 5. When the package is a conventional cap, the first cap conveying component 8 is fixed to the connecting ring 5 and corresponds to the conventional cap removal point on the cam; when the package is a motion cap, the second cap conveying component 9 is fixed to the connecting ring 5 and corresponds to the motion cap removal point on the cam. In this way, the cap removal problem of the motion cap with large differences is solved. At the same time, by changing the capping head cap mold 4, the action of taking the cap and sealing the cap on the conveying cap path is realized. In this way, the particularity of the sports cap is technically solved, while the conventionality of the conventional cap is compatible. Technically, these two types of caps with different structures are integrated into one machine to achieve an integrated sealing function.

[0031] The capping head 3 is movably connected to the inner wall of the connecting ring 13. The differential motor 7 is arranged at the top of the rotating assembly 2. The main transmission mechanism 1 is arranged below the rotating assembly 2. The connecting ring 13 is arranged below the transmission gear 10. The transmission gear 10 is arranged below the rotating support 5.

[0032] Its working principle is as follows: This integrated technology has three important technical structures: First, through the middle differential motor 7 and the slewing support 5, the requirements of different cap pitches on the cam trajectory are effectively compensated, so that one cam can adapt to the cap trajectory of different pitches; second, through the cam stroke height compensation, the problem of difficulty in taking the cap caused by the significant height difference between the moving cap and the conventional cap is solved, and at the same time, the scale of the scale adjustment rod 11 is presented to improve the debugging efficiency during the change; third, the two sets of cap conveying components are easy to disassemble and assemble, and at the same time, the problem of taking the cap due to the significant height difference between the moving cap and the conventional cap is solved. These three parts each realize their own functions, realize cam curve compensation, and accurately take the cap and stabilize the cap according to the height difference between the special shape of the moving cap and the conventional cap, and finally complete the sealing action and achieve a satisfactory sealing effect.

[0033] The advantages of its structure are: it realizes the integration of special motion cover and conventional cover in one machine, solves the problem of manufacturers configuring multiple models, increasing machine plant and adding technical operation staff when they need to use special cover type and conventional cover type packaging, and improves the sealing technology of the original interface in the most optimized way, so that the sealing of special motion cover and conventional cover can be realized on one machine. As a result, it saves cost investment and management for manufacturers to a great extent in many aspects, greatly improves production efficiency, and meets the needs of manufacturers at the same time. Therefore, on the basis of ensuring effective sealing, this design effectively reduces the cost investment and management of manufacturers, and while meeting the production of various cover type packaging of manufacturers, it greatly improves the practicality of the product and the humanization of production.

[0034] The rotary sealing device for rotary PET bottles and glass bottles with integrated conventional PET caps and special motion caps drives the rotary assembly to rotate around the center of the main transmission through the main transmission during operation. At the same time, the capping head, under the meshing transmission of the gears, rotates the rotating body along the trajectory of the cam, realizing the revolution around the main transmission and the rotation of the capping head at the same time, thereby completing the reciprocating action of grabbing, screwing in the cap and detaching the container.

[0035] In fact, there is a significant height difference between the special sports cap and the conventional PET screw cap, and the appearance structure is very different. Therefore, it is impossible to achieve the sealing of both the conventional PET screw cap and the special sports cap on the conventional sealing device. In order to achieve the sealing of the special sports cap and the conventional PET screw cap with one machine, a special integrated conventional PET cap and special sports cap rotary sealing device technology suitable for PET bottles and glass bottles is specially designed. This solves the cost investment of multiple machines and site investment while meeting the sealing requirements, and reduces labor investment, greatly reducing costs, and greatly improving product performance and demand satisfaction.

[0036] The technology of integrated conventional PET caps and special motion caps for PET bottles and glass bottles is optimized to achieve the integration of conventional PET screw caps and special motion caps. The following optimization designs are made: differential motors are configured on the rotary assembly to meet the screwing requirements of different caps through differential motor compensation to achieve the best sealing effect; the cam is specially designed to increase the up and down stroke of the cam track, and two cap removal points are designed to compensate for the height difference between the special motion cap and the conventional PET screw cap, so as to perfectly complete the cap removal action; different cap molds are designed, and different caps are matched by replacing the cap molds on the capping head to achieve the action of grabbing and sealing on the same device. Since it is suitable for different packaging, there are many change parts for the integrated device. Therefore, each time the packaging is changed, the height of the machine needs to be slightly adjusted to achieve the best sealing effect. Therefore, an adjustment rod with scales is set on this device so that the operator can remember the scales corresponding to different packaging, which greatly reduces the debugging workload for the operator.

[0037] The present invention is a technology of integrated conventional PET cap and special motion cap rotary sealing device for PET bottles and glass bottles, which is intended to solve the following problems: In the field of beverage production, due to the market demand targeted and adapted by manufacturers, manufacturers will use a variety of packaging materials to meet the market demand during production. When manufacturers use conventional PET threaded caps, they also need to use motion caps that meet the market demand. In this way, according to the existing technology, the manufacturer must configure two sets of production equipment at the same time to meet the production. In this way, not only the machine cost investment is increased, but also the area of ​​the factory to place the machine needs to be increased. At the same time, operators need to be equipped accordingly. In this way, no matter from which aspect, the investment cost of the manufacturer is greatly increased. A technology of integrated conventional PET cap and special motion cap rotary sealing device for PET bottles and glass bottles integrates the sealing technology of heterosexual packaging materials into one machine, and at the same time solves the problems of low machine cost investment, small machine footprint, and low operator labor, which actually realizes the purpose of reducing costs and increasing efficiency for manufacturers.

[0038] The present invention effectively compensates for the differential motor to meet the screwing requirements of different lids to achieve the best sealing effect; the special design of the cam track distributes two lid removal points to achieve the one-machine sealing effect of sports lids and conventional lids with significant height differences. The adjustment rod marked with scales ensures that when changing the packaging material, the operator can accurately and quickly adjust to the right position, thereby improving work efficiency and sealing effect.

[0039] The purpose of the present invention is to achieve the sealing of multiple packages by one machine by replacing the change parts when the manufacturer has both the demand for sealing with a moving cover and the demand for sealing with a conventional cover. This allows the manufacturer to meet the market demand while solving the cost investment of multiple machines and site investment, and reducing labor investment, thereby greatly reducing the output cost and greatly improving the performance of the product and the satisfaction of the demand.

[0040] The integrated conventional PET cap and special motion cap rotary sealing device technology for PET bottles and glass bottles effectively solves the problems of manufacturers, thereby greatly improving the energy efficiency of production and the practicality of the machine.

[0041] The integrated conventional PET cap and special motion cap rotary sealing device for PET bottles and glass bottles of the present invention can ensure the sealing effect, and effectively integrate the use of special motion caps and conventional caps, which are packaging materials with significant differences in appearance, into one machine through differential compensation, special cam track design, and configuration of the conveying cap assembly. Under the premise of meeting the manufacturer's use goals for a variety of packaging materials, it greatly reduces the manufacturer's investment in configuring multiple sets of machines, expanding the plant area, and increasing technical operators, fundamentally saving the manufacturer a huge amount of cost investment and management, greatly improving production efficiency, and meeting the manufacturer's needs at the same time.
