Description

Technical Field

[0001] This invention relates to the field of capping machine technology, specifically a capping device for bottled beverage production. Background Technology

[0002] In the industrial production of bottled beverages, the capping process is a key step in ensuring the sealing performance and quality of the product. Capping machines have become core equipment due to their strong adaptability and controllable operation. The industry has formed a product system of capping machines with multiple types and specifications. There are fully automatic capping machines suitable for high-speed production lines of large beverage companies, semi-automatic capping machines for small and medium batch production scenarios, and miniature equipment such as benchtop capping machines, which are mostly used for laboratory sample preparation.

[0003] Semi-automatic capping machines are widely used in small and medium-sized beverage production enterprises, regional specialty beverage processing workshops, and new beverage trial production lines due to their advantages such as low equipment investment cost, small footprint, and convenient production changeover and debugging. These enterprises often produce many batches with small output per batch, and the bottle type and cap specifications are flexible and varied. The high investment and long debugging cycle of fully automatic capping machines are difficult to match their production rhythm, while semi-automatic capping machines can quickly adapt to the capping needs of different bottled beverages by simply adjusting the capping head specifications and torque parameters.

[0004] However, existing semi-automatic capping machines require operators to manually place the capped bottles into the capping station and remove them manually after capping. This poses significant safety hazards. When placing or removing bottles, operators must extend their hands into the narrow area between the capping head and the bottle clamp. If there is a slight error in the start-up and shutdown control of the equipment, or if the operator deviates from their actions due to fatigue, accidents such as hand injuries from being caught in the clamp or being hit by the capping head are very likely to occur. Therefore, a capping device for bottled beverage production is proposed. Summary of the Invention

[0005] Therefore, the purpose of this invention is to provide a capping device for bottled beverage production to solve the technical problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a capping device for bottled beverage production, comprising a base, the base comprising a worktable and a moving table, the moving table being fixedly mounted with a guide rod and a sliding seat being slidably mounted on the guide rod, the worktable being fixedly mounted with a fixed seat and a motor being fixedly mounted on the top of the fixed seat;

[0007] A cylinder is fixedly installed on the motion platform, and both sides of the cylinder are connected to one side of the sliding seat through a hinge mechanism for pushing the sliding seat. A push rod is slidably installed on the inner wall of the cylinder, and the other end of the push rod is fixedly connected to a sliding box. A positioning mechanism is fixedly installed at the bottom of the worktable, and the positioning mechanism works in conjunction with the sliding box to guide the vertical lifting and lowering of the worktable. A support base is fixedly installed at the bottom of the worktable, and the bottom of the support base is fixedly connected to the base to limit the movement trajectory of the support base. A first capping wheel is rotatably installed at the bottom of the fixed base, and two sets of second capping wheels are rotatably installed at the bottom of the sliding seat. Helical gear sets are provided on the top of the first and second capping wheels, and a drive assembly is provided between the multiple sets of helical gear sets for the multiple sets of second capping wheels and the first capping wheel to rotate synchronously.

[0008] By adopting the above technical solution, the coordinated action of opening and closing of the sliding seat and lifting of the worktable is realized. Before the device is started, the worktable is in a low position, and the operator can complete the feeding in the safe area where the capping wheel is open. The dual movement can be completed by a set of cylinders, which simplifies the equipment structure and reduces energy consumption. It effectively solves the problem of high risk of manual operation of traditional semi-automatic capping machines and has significant application value in the production of small and medium batches of bottled beverages.

[0009] Furthermore, a fixed plate is fixedly installed on the top of the workbench, and telescopic mechanisms are fixedly installed on both sides of the fixed plate. A clamping block is fixedly installed at the other end of the telescopic mechanism, and a spring is provided inside the telescopic mechanism for clamping bottles of various sizes.

[0010] By adopting the above technical solution, the built-in spring of the telescopic mechanism, combined with the arc-shaped anti-slip design of the clamping block, can not only prevent the bottle from being scratched or deformed, but also ensure that bottles of different sizes can be stably clamped.

[0011] Furthermore, the positioning mechanism has multiple sets of fixed installations at the bottom of the worktable, and the bottom of the positioning mechanism is provided with multiple sets of pulleys to reduce the friction with the sliding box. The positioning mechanism has sliding columns fixedly installed on both sides, and the inner wall of the sliding box has sliding grooves corresponding to the sliding columns on both sides. When the push rod pushes the sliding box to move, the sliding columns and sliding grooves cooperate with each other, and the positioning mechanism drives the worktable to move up and down.

[0012] By adopting the above technical solution, the movement trajectory of the worktable can be strictly limited, ensuring that it only moves up and down in the vertical direction, avoiding misalignment of the cap due to offset, improving the capping accuracy, and the bottom pulley converts sliding friction into rolling friction, greatly reducing movement resistance, reducing component wear, and extending the service life of the equipment.

[0013] Furthermore, the sliding box is provided with a ramp corresponding to the positioning mechanism inside, so that the positioning mechanism can move up or down more smoothly. The bottom of the sliding box is provided with a guide mechanism that cooperates with the base to guide the sliding direction of the sliding box.

[0014] By adopting the above technical solution, the smooth slope of the landslide and the positioning mechanism pulley work together precisely to efficiently convert horizontal power into vertical lifting force, avoid movement jamming, ensure the smooth lifting of the worktable, and strictly limit the movement direction of the sliding box to prevent deviation in power transmission caused by offset.

[0015] Furthermore, the hinge mechanism includes a linkage plate, a connecting rod, and a hinge rod. The linkage plate is fixedly installed at the end of the push rod adjacent to the cylinder, and the connecting rod is fixedly installed on both sides of the linkage plate. The hinge rod is hingedly installed at the end of the connecting rod adjacent to the sliding seat, and the other end of the hinge rod is hingedly installed on the side of the sliding seat adjacent to the cylinder. When the push rod is in motion, the hinge rod pushes the sliding seat to slide along the guide rod.

[0016] By adopting the above technical solution, the power of the cylinder push rod to the sliding seat is efficiently and flexibly transmitted. The power transmission efficiency is high, and the two sets of sliding seats can be driven by only a single power source, the cylinder.

[0017] Furthermore, the outer diameter of the first capping wheel is larger than that of the second capping wheel, and the first and second capping wheels cooperate with each other to tighten the bottle cap when the sliding seat approaches the fixed seat.

[0018] By adopting the above technical solution, the differential design of the diameters of the No. 1 and No. 2 capping wheels enables the device to better adapt to bottle caps of different diameters, simplifying changeover operations and improving production efficiency.

[0019] Furthermore, both the first and second capping wheels are fixedly equipped with inner rotating shafts, and the first capping wheel is rotatably connected to the motor through the inner rotating shaft. An outer sleeve is fitted around the inner rotating shaft, and the top of the outer sleeve is fixedly connected to the fixed seat and the sliding seat respectively.

[0020] By adopting the above technical solution, the outer sleeve cooperates with the inner rotating shaft through the built-in bearing, which not only realizes the free rotation of the inner rotating shaft, but also restricts its radial wobble, ensuring the coaxiality of the capping wheel when it rotates, and avoiding capping deviation caused by shaft offset.

[0021] Furthermore, a connecting block is fitted on the outer wall of the outer sleeve of the first capping wheel, and pressure sensors are fixedly installed on both sides of the connecting block to sense the pressure of the bottle cap and send an electrical signal to the motor.

[0022] By adopting the above technical solution, the pressure changes during bottle cap contact and tightening can be accurately captured, and the motor can be automatically started and stopped through electrical signal feedback.

[0023] Furthermore, two sets of bearings are fixedly installed in the middle of the fixed base to support the rotating shaft of the helical gear set inside the fixed base. The two ends of the rotating shaft of the helical gear set inside the fixed base are connected to the helical gear set rotatably installed on the inner wall of the sliding seat through a drive assembly, which is used to synchronously drive the second capping wheel to rotate. The drive assembly includes two sets of retaining blocks and multiple sets of transmission rods. Multiple sets of transmission rods are hinged between the two sets of retaining blocks to maintain synchronous rotation between the helical gear sets without interfering with the sliding of the sliding seat. The fixed base is provided with drive assemblies on both sides to connect with the sliding seat.

[0024] By adopting the above technical solution, the linkage structure of the drive component can not only flexibly adapt to the movement trajectory of the sliding seat and maintain the synchronous rotation of the helical gear set during the opening and closing of the sliding seat, but also avoid power transmission interruption or jamming, ensure consistent rotation speed of the capping wheel, and improve the capping accuracy.

[0025] In summary, the present invention has the following main beneficial effects:

[0026] This invention integrates a cylinder-driven mechanical linkage structure with a synchronous motor transmission system to achieve coordinated action between the opening and closing of the capping wheel and the lifting and lowering of the worktable during the bottle capping process. This effectively solves the technical problems of traditional semi-automatic capping machines, such as easy hand pinching and low positioning accuracy during manual bottle handling. Before the device starts, the worktable is in a low position, allowing operators to load the bottle from a safe area away from the capping wheel. The extension and retraction of the cylinder push rod synchronously drives two sets of sliding seats to slide relative to or in opposite directions via a hinge mechanism. Simultaneously, the inclined surfaces of the sliding box and the positioning mechanism work together to precisely lift and lower the worktable, allowing the bottle to... The cap and the capping rollers always maintain an optimal fit, significantly improving the coaxiality and stability of the capping. The motor power is transmitted through a helical gear set and a hinged drive assembly, enabling the synchronous rotation of the first and second capping rollers. Combined with the electrical signal feedback from the pressure sensor, the capping action can be automatically triggered and the tightening torque can be precisely controlled, avoiding the problems of leakage due to loose caps or breakage due to excessive tightness. This ensures the consistency of capping quality. The mechanical linkage structure of the entire device does not require complex electrical control modules, making maintenance convenient and operation highly reliable. It improves capping efficiency and has strong industrial applicability. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The embodiments of the present invention will now be described.

[0040] A capping device for bottled beverage production, such as Figure 1-10As shown, the device includes a base 1, which includes a worktable 2 and a motion table 3. The motion table 3 provides an installation base for transmission components such as cylinder 5 and guide rod 33. The worktable 2 serves as a platform for carrying and positioning bottled beverages. The two work together to form the core support structure of the device. The motion table 3 is fixedly installed with guide rod 33, and a sliding seat 32 is slidably installed on the guide rod 33. The guide rod 33 provides linear motion guidance for the sliding seat 32, ensuring that the sliding seat 32 only approaches or moves away from the fixed seat 31 in the horizontal direction, avoiding radial offset from affecting the capping accuracy. The worktable 2 is fixedly installed with a fixed seat 31, and a motor 4 is fixedly installed on the top of the fixed seat 31. The fixed seat 31 not only provides a stable mounting point for the motor 4, but also serves as a rotation support base for the first capping wheel 312. At the same time, the built-in helical gear set 41 can realize the initial transmission of power from the motor 4.

[0041] A cylinder 5 is fixedly installed on the motion table 3, and both sides of the cylinder 5 are connected to one side of the sliding seat 32 through a hinge mechanism. This cylinder 5 is used to push the sliding seat 32. The cylinder 5 acts as a power source, and the extension and retraction of its push rod 53 converts linear power into the opening and closing power of the sliding seat 32 through the hinge mechanism, achieving synchronous reverse or relative movement of the two sets of sliding seats 32. A push rod 53 is slidably installed on the inner wall of the cylinder 5, and the other end of the push rod 53 is fixedly connected to a sliding box 54. While transmitting power from the cylinder 5, the push rod 53 can simultaneously drive the sliding box 54 to perform horizontal reciprocating motion, providing linkage conditions for the lifting and lowering of the worktable 2. A positioning mechanism 24 is fixedly installed at the bottom of the worktable 2, and the positioning mechanism 24 works in conjunction with the sliding box 54 to guide the vertical lifting and lowering of the worktable 2. The positioning mechanism 24 cooperates with the sliding groove 542 of the sliding box 54 through a sliding column 241, combined with the internal sliding slope structure of the sliding box 54, to convert the horizontal movement of the sliding box 54 into the vertical lifting and lowering movement of the worktable 2. A support base 11 is fixedly installed, and the bottom of the support base 11 is fixedly connected to the base 1 to limit the movement trajectory of the support base 11. The support base 11 adopts a linear guide structure to ensure that the workbench 2 only moves up and down in the vertical direction, avoiding tilting during the lifting process. A first capping wheel 312 is rotatably installed at the bottom of the fixed base 31, and two sets of second capping wheels 321 are rotatably installed at the bottom of the sliding base 32. The first capping wheel 312 is the active capping wheel, and the second capping wheel 321 is the driven capping wheel. The two work together to form a clamping and rotating structure for the bottle cap. The top of the first capping wheel 312 and the second capping wheel 321 are provided with helical gear sets 41, and a drive assembly is provided between the multiple sets of helical gear sets 41 for the synchronous rotation of the multiple sets of second capping wheels 321 and the first capping wheel 312. The drive assembly achieves synchronous power transmission between the helical gear sets 41 without interfering with the movement of the sliding base 32 through the holding block 42 and the hinged transmission rod 421, ensuring the consistency of the rotation of the capping wheels.

[0042] Please see Figure 1-10A fixed plate 21 is fixedly installed on the top of the workbench 2. The fixed plate 21 serves as the mounting base for the telescopic mechanism 22. Through its rigid structure, it provides stable support for the telescopic mechanisms 22 on both sides, ensuring force balance during clamping. The telescopic mechanisms 22 are fixedly installed on both sides of the fixed plate 21. The telescopic mechanism 22 adopts a telescopic rod structure, and its extension stroke can be flexibly adjusted according to the bottle diameter to adapt to the clamping requirements of different bottle sizes. A clamping block 23 is fixedly installed at the other end of the telescopic mechanism 22. This clamping block 23 is connected to another set of pneumatically controlled clamping blocks. 23 forms a clamping mechanism. Two identical clamping mechanisms are set on the worktable 2, so that two bottles can be operated at the same time. The inner side of the clamping block 23 adopts an arc design and is fitted with anti-slip material, which can increase the contact area with the bottle body, avoid scratching the bottle body during clamping, and increase friction to prevent the bottle body from shifting. The telescopic mechanism 22 is equipped with a spring inside, which is used to clamp bottles of various sizes. The spring has a preset elastic tension. After the clamping block 23 contacts the bottle, it can automatically adapt to the diameter of the bottle body through its own deformation to achieve quick positioning and fixation.

[0043] Please see Figure 1-10 Multiple positioning mechanisms 24 are fixedly installed at the bottom of the worktable 2. These multiple positioning mechanisms 24 are linearly distributed along the bottom of the worktable 2, which can avoid single-point force during the lifting and lowering of the worktable 2. The bottom of the positioning mechanism 24 is equipped with multiple sets of pulleys to reduce friction with the sliding box 54. The pulleys are made of wear-resistant nylon, and when they come into contact with the sliding ramp inside the sliding box 54, they can convert sliding friction into rolling friction, significantly reducing motion resistance and making the lifting and lowering of the worktable 2 smoother. This also reduces component wear and extends service life. Sliding columns 241 are fixedly installed on both sides of the positioning mechanism 24, and the sliding box 54... The inner wall has grooves 542 on both sides corresponding to the sliding column 241. When the push rod 53 pushes the sliding box 54 to move, the sliding column 241 and the groove 542 cooperate with each other. The positioning mechanism 24 drives the worktable 2 to move up and down. When the sliding box 54 slides horizontally under the push rod 53, the pulley at the bottom of the positioning mechanism 24 rolls up and down along the slope of the sliding box 54. Combined with the guidance of the sliding column 241 and the groove 542, the horizontal power of the sliding box 54 is converted into the vertical lifting force of the positioning mechanism 24, which in turn drives the worktable 2 to move up and down synchronously, so as to achieve precise fitting between the bottle cap and the capping wheel.

[0044] Please see Figure 1-10The sliding box 54 has a ramp inside that corresponds to the positioning mechanism 24. The ramp has a smooth inclined surface design, and the inclination angle of the ramp is preset according to the required lifting stroke of the worktable 2. Each positioning mechanism 24 has an independent ramp, which ensures that multiple positioning mechanisms 24 are subjected to force and lifted synchronously. This allows the positioning mechanism 24 to move up or down more smoothly. The bottom of the sliding box 54 is provided with a guide mechanism 541 that cooperates with the base 1. The guide mechanism 541 adopts a slide rail + slider structure. The slide rail is opened on the base 1, and the slider is fixed to the bottom of the sliding box 54. The slide rail is parallel to the axis of the cylinder 5. It is used to guide the sliding direction of the sliding box 54 and can strictly limit the sliding box 54 to move only in the horizontal direction (consistent with the extension and retraction direction of the push rod 53), so as to avoid the sliding box 54 from deviating and causing the ramp and positioning mechanism 24 to be misaligned.

[0045] Please see Figure 1-10 The hinge mechanism includes a linkage plate 501, a connecting rod 51, and a hinge rod 52. The linkage plate 501 is fixedly installed at the end of the push rod 53 adjacent to the cylinder 5. As a power transfer component, the linkage plate 501 can move horizontally reciprocating synchronously with the push rod 53. The connecting rod 51 is fixedly installed on both sides of the linkage plate 501 and can move synchronously with the movement of the linkage plate 501. The hinge rod 52 is hingedly installed at the end of the connecting rod 51 adjacent to the sliding seat 32, and the other end of the hinge rod 52 is hingedly installed on the side of the sliding seat 32 adjacent to the cylinder 5. The hinge rod 52 converts the linear motion of the connecting rod 51 into a push rod by rotating the two ends. The horizontal power of the sliding seat 32 can be adjusted by its own angle to ensure a smooth power transmission process. When the push rod 53 is in motion, the hinge rod 52 pushes the sliding seat 32 to slide along the guide rod 33. When the push rod 53 extends, the linkage plate 501 drives the connecting rod 51 to move forward. The angle of the hinge rod 52 increases and pushes the two sets of sliding seats 32 to slide in opposite directions along the guide rod 33. When the push rod 53 retracts, the linkage plate 501 pulls the connecting rod 51 to move backward. The angle of the hinge rod 52 decreases and pulls the two sets of sliding seats 32 to slide in opposite directions along the guide rod 33, realizing the synchronous linkage between the opening and closing of the sliding seat 32 and the movement of the push rod 53.

[0046] Please see Figure 1-10The outer diameter of the first capping wheel 312 is larger than that of the second capping wheel 321. The first capping wheel 312, as the main capping wheel, bears the main driving force for tightening, while the second capping wheel 321, as the auxiliary capping wheel, plays the role of clamping and assisting rotation. The difference in diameter between the two can better adapt to bottle caps of different sizes. The first capping wheel 312 and the second capping wheel 321 cooperate with each other. When the sliding seat 32 approaches the fixed seat 31, the first capping wheel 312 and the second capping wheel 321 tighten the bottle cap. When the sliding seat 32 moves along the guide rod 33 towards the fixed seat 31, the second capping wheel 321 moves closer to the first capping wheel 312 with the sliding seat 32 until the two are in contact with the bottle cap from both sides. Under the drive of the motor 4, they rotate synchronously, gradually tightening the bottle cap on the bottle mouth and completing the capping action.

[0047] Please see Figure 1-10 Both the first capping wheel 312 and the second capping wheel 321 are fixedly equipped with an inner rotating shaft 302. The inner rotating shaft 302 can stably transmit the rotational power of the motor 4 to the capping wheel, ensuring sufficient torque output and no slippage during capping. The first capping wheel 312 is rotatably connected to the motor 4 through the inner rotating shaft 302. The output shaft of the motor 4 is coaxially connected to the inner rotating shaft 302 of the first capping wheel 312, which can minimize torque loss during power transmission and ensure efficient output of capping power. An outer sleeve 301 is sleeved on the outside of the inner rotating shaft 302. The outer sleeve 301 is a hollow cylindrical structure. A bearing is installed between its inner wall and the inner rotating shaft 302, so that the inner rotating shaft 302 can rotate freely inside the outer sleeve 301 without radial wobble. The top of the outer sleeve 301 is fixedly connected to the fixed seat 31 and the sliding seat 32 respectively.

[0048] Please see Figure 1-10 The outer wall of the outer sleeve 301 of the first capping wheel 312 is fitted with a connecting block 313. The connecting block 313 adopts a clamping structure and can be finely adjusted along the axial direction of the outer sleeve 301 to adapt to the pressure sensing requirements of bottle caps of different heights. Pressure sensors 314 are fixedly installed on both sides of the connecting block 313 to sense the pressure of the bottle cap and send an electrical signal to the motor 4. When the worktable 2 rises and the bottle cap is pressed against the pressure sensor 314, the bottle cap exerts a squeezing force on the pressure sensor 314. After the pressure sensor 314 detects the preset pressure value, it immediately sends a start electrical signal to the motor 4 to realize the automatic start and stop of the capping action.

[0049] Please see Figure 1-10Two sets of bearing seats 311 are fixedly installed in the middle of the fixed base 31 to support the rotating shaft of the helical gear set 41 inside the fixed base 31. The bearing seats 311 have built-in high-precision rolling bearings, which can provide stable support for the rotating shaft of the helical gear set 41 and reduce the frictional resistance when the shaft rotates, ensuring smooth power transmission. The two ends of the rotating shaft of the helical gear set 41 inside the fixed base 31 are connected to the helical gear set 41 rotatably installed on the inner wall of the sliding base 32 through the drive assembly, which is used to synchronously drive the second capping wheel 321 to rotate. The helical gear set 41 inside the fixed base 31 divides the power of the inner rotating shaft 302 of the first capping wheel 312 to the drive assembly through the two ends of the shaft, and then the drive assembly transmits it to the helical gear set 41 inside the sliding base 32, which finally drives the inner rotating shaft 302 of the second capping wheel 321 to rotate, realizing the power synchronization of the first capping wheel 312 and the second capping wheel 321. The drive assembly includes two sets of bearing seats 311. The retaining block 42 and multiple sets of transmission rods 421 are fixedly connected to the rotating shaft of the helical gear set 41 inside the fixed seat 31 and the rotating shaft of the helical gear set 41 inside the sliding seat 32, respectively. Multiple sets of transmission rods 421 are hinged between the two sets of retaining blocks 42 to maintain synchronous rotation between the helical gear sets 41 without interfering with the sliding of the sliding seat 32. When the sliding seat 32 moves closer to or away from the fixed seat 31 along the guide rod 33, the transmission rods 421 can be flexibly folded or unfolded with the relative movement of the retaining blocks 42, changing the length while keeping the power transmission direction unchanged, ensuring that the helical gear set 41 always rotates synchronously, and that there will be no jamming or power interruption due to the movement of the sliding seat 32. Both sides of the fixed seat 31 are provided with drive components that are connected to the sliding seat 32. The drive components arranged symmetrically on both sides can make the sliding seats 32 on both sides bear forces evenly, and at the same time further ensure the synchronous rotation of the two sets of second-stage cover wheels 321.

[0050] The working principle of this invention is as follows: Before the device is started, the push rod 53 in the cylinder 5 is in a fully extended state, the two sets of sliding seats 32 are in an open state that are far apart from each other along the guide rod 33, the first capping wheel 312 and the second capping wheel 321 maintain a distance, the sliding box 54 is located at the front end of the stroke, and the pulley of the positioning mechanism 24 is in contact with the low point of the sliding slope inside the sliding box 54, so that the worktable 2 is kept in the initial low position after the descent, which makes it convenient for the operator to place the bottled beverage to be capped on the worktable 2;

[0051] The operator places two bottles of beverage to be capped on the low workbench 2. The telescopic mechanism 22 on both sides of the fixing plate 21 relies on the elastic force of the internal spring to drive the clamping block 23 to automatically adjust the clamping distance according to the bottle size. It cooperates with the clamping block 23 on the other side to clamp and fix the bottle body to prevent it from shifting during subsequent capping.

[0052] After the bottle is fixed, the cylinder 5 receives the start signal, the internal push rod 53 retracts and drives the linkage plate 501 to move backward, the connecting rod 51 pulls the hinge rod 52, the hinge rod 52 acts as a force transmission medium, and pulls the two sets of sliding seats 32 to slide along the guide rod 33 in the opposite direction to the fixed seat 31, until the first capping wheel 312 and the second capping wheel 321 gradually approach the two sides of the bottle cap. At the same time as the push rod 53 retracts, it pulls the sliding box 54 to slide backward along the guide mechanism 541. The pulley of the positioning mechanism 24 rolls from the low point to the high point on the slope of the sliding box 54. The inclined surface of the slope pushes the positioning mechanism 24 to move upward. The sliding column 241 and the sliding groove 542 guide the movement trajectory of the positioning mechanism 24, thereby driving the worktable 2 to rise through the telescopic movement of the support seat 11, so that the bottle cap is precisely fitted with the first capping wheel 312 and the second capping wheel 321.

[0053] When the bottle cap comes into contact with the pressure sensor 314 and is squeezed, the pressure sensor 314 detects the preset pressure value and immediately sends an electrical signal to the motor 4. The motor 4 starts and outputs power, driving the inner shaft 302 of the first capping wheel 312 to rotate. The inner shaft 302 transmits power to the drive assembly through the helical gear set 41 inside the fixed seat 31. The holding block 42 of the drive assembly is hinged to multiple sets of transmission rods 421. Without interfering with the sliding seat 32, the power is synchronously transmitted to the helical gear sets 41 inside the two sets of sliding seats 32, thereby driving the inner shafts 302 of the two sets of second capping wheels 321 to rotate synchronously.

[0054] After the capping is completed, the cylinder 5 receives a reset signal, the internal push rod 53 extends again, driving the linkage plate 501 to move forward, the connecting rod 51 pushes the hinge rod 52, so that the two sets of sliding seats 32 slide in opposite directions along the guide rod 33, and the first capping wheel 312 and the second capping wheel 321 disengage from the bottle cap and return to the open state.

[0055] As push rod 53 extends, it pushes sliding box 54 forward. The pulley of positioning mechanism 24 slides back to the lowest point along the slope of sliding box 54. Sliding column 241 slides to the lowest end of slide groove 542 in sync. Worktable 2 then descends to the initial low position. Support base 11 retracts to the lowest height. Operators can easily take out the bottled beverage with the caps on. Then, a new beverage to be capped is placed on worktable 2, and the device enters the next working cycle.
