Description

Technical Field

[0001] The present application relates to the technical field of capping machines, and in particular to a multifunctional capping machine. Background Art

[0002] When the outer packaging of paste-like items such as hand cream and toothpaste on the market is produced, one end of the packaging sleeve is first screwed and connected to the outer cover, and then filling and sealing are performed from the other end of the sleeve. Therefore, the outer packaging needs to be capped by a capping machine.

[0003] When the existing capping machine is in use, the bottle cap is clamped by a three-jaw clamp, but due to the limitation of the shape of the clamp, the existing clamp is mostly used only for clamping round bottle caps, and it is difficult to clamp special-shaped bottle caps. After the clamp is used for too long, the end used for clamping will wear out, resulting in reduced clamping effect on the bottle cap and easy scratching of the bottle cap surface. Therefore, the clamp needs to be replaced regularly. The existing clamp is mostly installed in the slide groove and other structures of the clamp itself. When it needs to be replaced, it is often necessary to replace the entire clamp or disassemble the entire clamp before replacing it, which is more troublesome during replacement.

[0004] Therefore, the present invention proposes a multifunctional capping machine to improve the problem. Summary of the invention

[0005] The purpose of this application is to solve the problems in the above-mentioned background technology, and the application provides a multifunctional cap locking machine.

[0011] Furthermore, a C-shaped hole is provided on the connecting rod, and the C-shaped hole is used to accommodate the blocking rod. The circular plate includes a plurality of fan-shaped plates, and the slide grooves are provided on the fan-shaped plates. When the fan-shaped plates slide, the blocking rod is driven to connect or separate with the C-shaped hole.

[0012] Furthermore, an expansion panel is installed on the free end of the push rod, a accommodating cavity is opened on the expansion panel, an inner wall of the accommodating cavity is opened with an inclined surface, a sliding rod is slidably installed on the fan-shaped plate through a return spring, one end of the sliding rod faces the accommodating cavity, and an arc plate is installed on the other end. When the inner wall of the accommodating cavity contacts the sliding rod, the sliding rods are forced to approach each other and a space for accommodating the bottle cap is formed between the arc plates.

[0013] Furthermore, a pressure plate is slidably mounted on the sector plate via a resisting spring, and the length of the resisting spring is smaller than the distance between the sector plate and the arc plate.

[0014] Furthermore, limiting rods are installed on two of the opposite fan-shaped plates, and limiting grooves for accommodating the limiting rods are provided on the other two opposite fan-shaped plates. The pressure plate is connected to the fan-shaped plate on which the limiting rods are installed. A guide hole is provided on the push rod, and a guide rod is slidably installed in the guide hole through a push spring. A channel that slidably cooperates with the guide rod is provided on the pressure plate. When the guide rod is inserted into the channel, the sliding of the fan-shaped plate is restricted.

[0016] Furthermore, a round rod is installed on the installation shell, a blocking piece is installed on the free end of the round rod, and the round rod is slidably matched with the body shell.

[0017] Furthermore, a camera is installed on the body shell, and the camera faces the mold rod in contact with the sleeve.

[0018] Furthermore, a contact ball is installed at the end of the sliding rod facing the accommodating cavity, and the sliding rod contacts the inner wall of the accommodating cavity through the contact ball.

[0019] The beneficial effects of this application are as follows:

[0020] When the present application is in use, air is blown toward the mounting shell and the mounting tube through the pneumatic tube, so that the mounting shell slides on the body shell and approaches the sleeve, and at the same time, the push rod is pushed to make it contact with the hinge rod, forcing the hinge rod to rotate. When the hinge rod rotates, it drives the connecting rod to move in the slide groove, and the blocking of the baffle rod provides a fulcrum for the connecting rod, so that the free end of the chuck is tilted to clamp the bottle cap. At this time, the driving motor drives the mounting tube to rotate, and then drives the chuck to rotate to lock the cap. Through the cooperation of multiple chucks, the contact points between the device and the bottle cap are increased, so that the bottle cap can be better clamped. When the chuck needs to be replaced, the threaded connection between the connecting rod and the hinge block can be released by rotating, which increases the convenience of replacing the chuck.

[0021] When the present application is in use, when the pneumatic tube is blowing, the airflow will enter the branch tube, but part of the airflow will flow back into the pneumatic tube through the connecting tube. At this time, the airflow will directly push the mounting shell, but the airflow in the branch tube needs to blow the baffle first. Due to the influence of the airflow and the gravity of the mounting shell itself, it will first approach the mold rod. When it slides to the maximum limit, the airflow cannot blow the mounting shell and can only blow the baffle to make it enter the mounting tube. At this time, the airflow enters the mounting tube to push the push rod. Through the above-mentioned arrangement, the mounting shell can drive the position where the chuck contacts the bottle cap and then makes the free ends of the chuck approach each other. When the mounting shell is close to the sleeve, it can also press and hold the bottle cap so that the unthreaded part is inserted on the sleeve, so that the bottle cap can be more stably connected to the sleeve when tightened, thereby increasing the practicality of the device.

[0022] In the present application, when the connecting rod needs to be disassembled, the fan-shaped plates are slid away from each other, so that the blocking rod is separated from the C-shaped hole, and then the blocking rod is separated from the C-shaped hole, so that the rotation of the connecting rod around its own axis is restored and it can be separated from the hinge block. When the connecting rod is installed, the fan-shaped plates are slid close to each other, so that the blocking rod contacts the opening of the C-shaped hole. At this time, the rubber sleeve outside the blocking rod is deformed so that it can enter the C-shaped hole to complete the connection. When in use, the stability of the connecting rod is increased by the above-mentioned arrangement.

[0023] When the present application is in use, when the push rod approaches the circular plate and drives the connecting rod to rotate, the sliding rod is also resisted by the inner wall of the accommodating cavity. The sliding rods are guided by the inclined surface to approach each other, thereby driving the arc plates to approach each other, so that the arc plates form a barrier outside the bottle cap, limiting the movable space of the bottle cap on the sleeve. At this time, the chuck clamps the sleeve. If the bottle cap is too long and the center of gravity is too large during transportation, the bottle cap will be in a skewed state. When the bottle cap is in a skewed state, it is easy to cause the thread to be misaligned and unable to be tightened. At this time, it is straightened by the resistance of the arc plate, so that the axis of the bottle cap thread is in line with the axis of the sleeve, which is convenient for subsequent tightening, thereby increasing the feasibility of the device.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Embodiment 1

[0039] like Figure 1 - Fig.13 As shown, a multifunctional capping machine proposed in the first embodiment of the present application comprises a machine body shell 1, on which a turntable 101 is rotatably mounted, a mold rod 102 is mounted on the turntable 101, a pneumatic suction head 103 is mounted on the machine body shell 1, the pneumatic suction head 103 is used to sleeve a sleeve onto the mold rod 102 or separate the sleeve from the pneumatic suction head 103, an electronic eye 104 facing the mold rod 102 is mounted on the machine body shell 1, conveyor belts are mounted on both sides of the machine body shell 1, one of which is used to transport uncapped sleeves and the other is used to transport capped sleeves, the pneumatic suction head 103 is connected to the cylinder, and the pneumatic suction head 103 is connected to the cylinder. The swing arm mechanism is installed on the body shell 1. The swing arm mechanism is a prior art and is driven by a servo motor. The pneumatic suction head 103 generates negative pressure by suction to suck and transport the sleeve, so that the sleeve can be transported from the conveyor belt to the mold rod 102 or from the mold rod 102 to the conveyor belt. The electronic eye 104 is a prior art and includes a camera probe and a positioning sensor, which is used to detect the sleeve located on the mold rod 102 to detect whether its top is connected to the cap body. The side wall of the body shell 1 also transports the bottle cap through a vibrating screen and transports it to the top of the sleeve through the pneumatic suction head 103 to pre-connect the two.

[0040] Among them, a plurality of pneumatic suction heads 103 are installed on the body shell 1, and the device also feeds the bottle caps through the pneumatic suction head 103. The bottle caps are adsorbed by the pneumatic suction head 103, and the air pressure adsorption reduces the possibility of the surface of the bottle caps being scratched by hard clamping when the bottle caps are clamped. In the prior art, the bottle caps are fed through a vibrating screen, and horizontal feeding is not possible, resulting in more contact points between the peripheral side of the bottle caps and other bottle caps when the bottle caps are fed, and they are also more likely to be scratched. In the present application, the bottle caps are fed horizontally through the pneumatic suction head 103, so that the friction between the bottle caps is less when the bottle caps are fed, reducing the possibility of the bottle caps being scratched;

[0041] Among them, the housing 1 is also equipped with a positioning clutch. When in use, the bottle cap and the sleeve are aligned by the clutch and the existing roller friction alignment, which is more stable and tight, increases the effect of the combination of the bottle cap and the sleeve, and increases the stability of the device when in use;

[0042] Also includes:

[0043] The mounting shell 2 is slidably mounted on the housing 1 to Figure 1 From the main viewing angle, the mounting shell 2 is slidably connected to the housing 1 in the vertical direction;

[0044] A driving motor 201 is installed on the machine body shell 1, and a mounting tube 202 is rotatably installed on the mounting shell 2. A gear pair 203 is installed between the driving motor 201 and the mounting tube 202. One of the gears in the gear pair 203 is connected to the output end of the driving motor 201, and the other gear is slidably connected to the mounting tube 202. A plate body is installed on the machine body shell 1, and the gear connected to the gear pair 203 and the mounting tube 202 is rotatably connected to the plate body. A rod body is installed on the side wall of the mounting tube 202. A groove body for accommodating the rod body is opened on the above-mentioned gear, so that the gear can only slide with the mounting tube 202. The length of the rod body is less than the length of the mounting tube 202. The part of the mounting tube 202 where the rod body is not installed is rotatably connected to the mounting shell 2, so that it will not affect the rotation between the mounting tube 202 and the mounting shell 2. Figure 5 As shown, when the gear rotates, the groove pushes the side wall of the rod body to drive the mounting tube 202 to rotate. With this arrangement, when the mounting shell 2 slides, the position of the gear pair 203 will not move with the mounting shell 2, so that the two gears can always be meshed, which improves the feasibility of the device. When the device is used, the mounting tube 202 can rotate together by starting the drive motor 201 through the transmission of the gear pair 203.

[0045] A pneumatic tube 204 is installed on the installation shell 2, and the free end of the pneumatic tube 204 is connected to the air source. A branch tube 205 is installed on the pneumatic tube 204, and the branch tube 205 is communicated with the inside of the installation tube 202. The air source can be an air pump or an air cylinder. When in use, when air is blown into the pneumatic tube 204, the airflow pushes the installation shell 2 to slide close to the mold rod 102. When air is sucked into the pneumatic tube 204, negative pressure is generated in the pneumatic tube 204, so that the installation shell 2 is reset. The branch tube 205 is rotatably matched with the installation tube 202, so that when the installation tube 202 rotates, the branch tube 205 will not rotate, causing them to be twisted together and then blocking the branch tube 205, thereby increasing the feasibility of the device;

[0046] The circular plate 3 is mounted on the mounting shell 2. The circular plate 3 can rotate relative to the mounting shell 2. A push rod 206 is slidably mounted in the mounting tube 202. When air is blown in the pneumatic tube 204, the airflow pushes the push rod 206 to slide away from the mounting tube 202. When air is sucked in the pneumatic tube 204, negative pressure is generated in the pneumatic tube 204, so that the push rod 206 is reset. A plate body is mounted on the side wall of the push rod 206. A groove body for accommodating the plate body is opened on the inner wall of the mounting tube 202, so that the push rod 206 can only slide in the mounting tube 202 without relative rotation. When the mounting tube 202 rotates, the push rod 206 can be driven to rotate.

[0047] At least four slide grooves 301 are provided on the circular plate 3. A blocking rod 302 is installed in the slide groove 301. A connecting rod 303 is movably installed in the slide groove 301. A clamp 304 is installed at one end of the connecting rod 303. One slide groove 301 corresponds to one clamp 304. By increasing the number of clamps 304, the contact points between the device and the bottle cap are increased, so that the device can clamp the special-shaped bottle cap more stably, thereby improving the versatility of the device.

[0048] The other end of the connecting rod 303 is threadedly connected to a hinge plate 308, and a hinge rod 305 hinged to the push rod 206 is hinged on the hinge plate 308. The blocking rod 302 is used to resist the connecting rod 303. The connecting rod 303 can rotate around the blocking rod 302 in the slide groove 301 and can also rotate in the slide groove 301 along its own axis direction, so that it is movably connected with the slide groove 301;

[0049] When the device is in use, the pneumatic tube 204 blows air to make the push rod 206 move away from the mounting tube 202, which drives one end of the hinged rod 305 to move downward. During the movement, the other end of the hinged rod 305 pushes the connecting rod 303 away from the push rod 206, and the rod body of the connecting rod 303 is blocked by the blocking rod 302, so that the blocking rod 302 forms a fulcrum, so that the connecting rod 303 rotates, so that the end connected to the hinge plate 308 moves away from each other, and then the end connected to the clamp 304 approaches each other, so that the clamp 304 clamps the bottle cap. When the clamping is completed, the drive motor 201 is started through the detection of the electronic eye 104, so that the mounting tube 202 drives the push rod 206 to rotate, and then drives the circular plate 3 and the clamp 304 to rotate together to tighten the bottle cap;

[0050] When the chuck 304 needs to be replaced, the connecting rod 303 is rotated to release the threaded connection between the connecting rod 303 and the hinge plate 308, and the chuck 304 can be replaced without replacing the entire fixture or disassembling the fixture for replacement, which increases the convenience of replacing the chuck 304.

[0051] When the hinged rod 305 rotates, the connecting rod 303 is driven to move in the slide groove 301, and the blocking rod 302 is used to provide a fulcrum for the connecting rod 303, so that the free end of the clamp 304 is tilted to clamp the bottle cap. At this time, the driving motor 201 drives the mounting tube 202 to rotate, and then drives the clamp 304 to rotate to lock the cap. Through the cooperation of multiple clamps 304, the contact points between the device and the bottle cap are increased, so that the bottle cap can be better clamped. When the clamp 304 needs to be replaced, the threaded connection between the connecting rod 303 and the hinge plate 308 can be released by rotating, which increases the convenience of replacing the clamp 304. Embodiment 2

[0052] like Figure 5 and Fig.12 As shown, the second embodiment is based on the first embodiment and further discloses the pneumatic tube 204, the push rod 206 and the circular plate 3. In the second embodiment, a slide bar 4 for being inserted into the pneumatic tube 204 is installed on the mounting shell 2. The slide bar 4 is inserted into the pneumatic tube 204. When air is blown into the pneumatic tube 204, the airflow can be concentrated to push the slide bar 4. When the mounting shell 2 is away from the pneumatic tube 204, part of the airflow blown out will not escape in other directions, resulting in the possibility of power waste, thereby increasing the feasibility of the device.

[0053] The inner diameter of the branch pipe 205 is smaller than the inner diameter of the installation pipe 202. A baffle 6 is slidably installed in the branch pipe 205 through a connecting spring 5. The baffle 6 is used to block or unblock the passage between the branch pipe 205 and the installation pipe 202. Since the inner diameter of the installation pipe 202 is larger than the inner diameter of the branch pipe 205, the baffle 6 can block the inner cavity of the branch pipe 205, but cannot block the inner cavity of the installation pipe 202.

[0054] A connecting pipe 7 is installed between the branch pipe 205 and the pneumatic pipe 204. When in use, when the pneumatic pipe 204 blows air, the airflow will enter the branch pipe 205, but part of the airflow is blocked by the baffle 6 and flows back to the pneumatic pipe 204 through the connecting pipe 7. At this time, the airflow will directly push the installation shell 2, but the airflow in the branch pipe 205 needs to blow the baffle 6 first. Due to the influence of the airflow and the gravity of the installation shell 2 itself, the installation shell 2 will first approach the mold rod 102. When it slides to the maximum limit, the airflow cannot blow the installation shell 2 and can only blow the baffle 6. The mounting shell 2 moves to enter the mounting tube 202. At this time, the airflow enters the mounting tube 202 to push the push rod 206. Through the above arrangement, the mounting shell 2 can drive the clamp 304 to move to the position in contact with the bottle cap first, and then make the free ends of the clamp 304 approach each other to clamp the bottle cap, thereby improving the feasibility of the device. When the mounting shell 2 is close to the sleeve, the bottle cap can also be pressed and held, so that the unthreaded part of the bottle cap is inserted on the sleeve, so that the bottle cap can be more stably connected to the sleeve when being tightened, thereby increasing the practicality of the device.

[0055] like Figure 4 , Figure 6 and Fig.13 As shown, in the second embodiment, a C-shaped hole 8 is provided on the connecting rod 303, and the C-shaped hole 8 is used to accommodate the blocking rod 302. The blocking rod 302 is wrapped with rubber skin on the outside so that its diameter can be changed. When in use, the C-shaped hole 8 accommodates the blocking rod 302. The inner diameter of the C-shaped hole 8 is consistent with the rod diameter of the blocking rod 302 in the normal state, which will not affect the rotation of the connecting rod 303 around the blocking rod 302, and also increase the contact area between the connecting rod 303 and the blocking rod 302, so that the wear during the rotation is reduced, thereby increasing the practicality of the device;

[0056] When the blocking rod 302 is located in the C-shaped hole 8, its rod body blocks the inner wall of the C-shaped hole 8, thereby limiting the rotation of the connecting rod 303 around its own axis, so that the connecting rod 303 will not be separated from the hinge plate 308 by external forces when in use, thereby increasing the stability of the device when in use;

[0057] The circular plate 3 includes a plurality of sector plates 306, and the slide groove 301 is provided on the sector plates 306. When the sector plates 306 slide, the blocking rod 302 is driven to connect or separate with the C-shaped hole 8. The mounting shell 2 is rotatably mounted with a round block 24, and the sector plates 306 are slidably connected with the round block 24, so that when the chuck 304 needs to be rotated, the rotation of the round block 24 satisfies the rotation of the circular plate 3. When the connecting rod 303 needs to be disassembled, the sector plates 306 are slid to move away from each other, so that the blocking rod 302 is separated from the C-shaped hole 8. The retaining rod 302 is separated from the C-shaped hole 8, so that the rotation of the connecting rod 303 around its own axis is restored and it can be separated from the hinge plate 308. When the connecting rod 303 is installed, the fan-shaped plates 306 are slid close to each other, so that the retaining rod 302 contacts the opening of the C-shaped hole 8. At this time, the rubber skin on the outside of the retaining rod 302 is deformed so that it can enter the C-shaped hole 8 to complete the connection. When in use, the above-mentioned arrangement increases the stability of the connecting rod 303 during use.

[0058] like Figure 5 , Figure 8 and Fig.12 As shown, in the second embodiment, a spreading panel 9 is installed on the free end of the push rod 206, a receiving cavity 10 is opened on the spreading panel 9, an inclined surface is opened on the inner wall of the receiving cavity 10, and a sliding rod 307 is slidably installed on the sector plate 306 through a return spring 309, and the sliding direction of the sliding rod 307 is close to or away from the center of the circular plate 3;

[0059] When the inner wall of the accommodating chamber 10 contacts the sliding rod 307, the sliding rods 307 are forced to approach each other and a space for accommodating the bottle cap is formed between the curved plates 11. When the push rod 206 is close to the circular plate 3, the connecting rod 303 is driven to rotate, and the sliding rod 307 is also contacted by the inner wall of the accommodating chamber 10. The sliding rods 307 are guided by the inclined surface, and then the curved plates 11 are driven to approach each other, so that the curved plates 11 form a barrier outside the bottle cap, limiting the movable space of the bottle cap on the sleeve. At this time, the chuck 304 clamps the sleeve. If the bottle cap is too long and the center of gravity is too high during transportation, the bottle cap will be in a skewed state. When the bottle cap is in a skewed state, it is easy to cause the thread to be misaligned and cannot be tightened. At this time, it is straightened by the contact of the curved plate 11, so that the axis of the bottle cap thread is in line with the axis of the sleeve, which is convenient for subsequent tightening, thereby increasing the feasibility of the device.

[0060] like Fig.11As shown, in the second embodiment, a pressure plate 13 is slidably installed on the fan-shaped plate 306 through a resistance spring 12, and the length of the resistance spring 12 is less than the distance between the fan-shaped plate 306 and the arc plate 11. When the mounting shell 2 drives the circular plate 3 close to the mold rod 102, the fan-shaped plate 306 presses the bottle cap through the pressure plate 13, so that the bottle cap can be better connected to the sleeve, and the pressure plate 13 is in the process of pressing, The resistance spring 12 is compressed, and the pressure plate 13 and the resistance spring 12 cooperate to form a flexible extrusion, which reduces the damage to the bottle cap during pressing and reduces the possibility of cracking caused by hard pressing. The length of the resistance spring 12 is short. When the arc plate 11 resets the bottle cap, the bottle cap is pressed again, so that the bottle cap can be maintained in a position where its thread axis is in line with the sleeve axis, further increasing the stability of the bottle cap when it is not twisted, and facilitating a more stable subsequent twisting of the bottle cap.

[0061] like Fig.11 and Fig.12 As shown, in the second embodiment, two of the opposite sector plates 306 are provided with limiting rods 14, and the other two opposite sector plates 306 are provided with limiting grooves 15 for accommodating the limiting rods 14. When in use, when the sliding sector plates 306 are moved closer to each other, the limiting rods 14 are inserted into the limiting grooves 15. At this time, the limiting rods 14 limit the inner walls of the limiting grooves 15, so that the tendency of the sector plates 306 provided with the limiting grooves 15 to move away from each other is limited;

[0062] The pressing plate 13 is connected to the fan-shaped plate 306 on which the limiting rod 14 is installed. A guide hole 18 is provided on the pushing rod 206. A guide rod 17 is slidably installed in the guide hole 18 through the pushing spring 16. A hole that slidably cooperates with the guide rod 17 is provided on the pressing plate 13. When the guide rod 17 is inserted into the hole, the sliding of the fan-shaped plate 306 is restricted. When in use, the guide rod 17 is inserted into the hole. When the pressing plate 13 contacts the bottle cap, the pushing spring 16 and the contact spring 12 are compressed together, and the guide rod 17 slides into the guide hole 18 and is restricted by the inner wall of the guide hole 18, so that it can only slide in a straight line direction. At the same time, the inner wall of the hole on the pressing plate 13 is also restricted by the side wall of the guide rod 17, so that the pressing plate 13 can only slide in a straight line direction, which increases the stability of the pressing plate 13 when pressing the bottle cap.

[0063] Among them, there are two pressure plates 13 and they are respectively installed on the fan-shaped plates 306 equipped with the limiting rod 14. When in use, after aligning the channels on the pressure plate 13, the guide rod 17 is inserted into the channel to limit the sliding of the fan-shaped plate 306 equipped with the limiting rod 14. At this time, the sliding of the fan-shaped plate 306 is restricted, which increases the stability of the fan-shaped plate 306 when in use. When disassembly is required, the guide rod 17 is pressed in the direction close to the guide hole 18 to separate it from the channel, that is, the sliding of the fan-shaped plate 306 equipped with the limiting rod 14 can be restored, and then the above two are slid to separate the limiting rod 14 from the limiting groove 15, so that all the fan-shaped plates 306 can slide and restore. When in use, the guide rod 17 not only plays a guiding role, but also can drive the role of limiting sliding, thereby increasing the practicality of the device. Embodiment 3

[0064] like Figure 1 - Fig.13 As shown, the third embodiment is further disclosed on the basis of the second embodiment. In the third embodiment, the chuck 304 includes a base 3041 and a rotating portion 3042. The rotating portion 3042 is rotatably matched with the base 3041. The base 3041 is connected to the connecting rod 303.

[0065] The rotating part 3042 has clamping blocks 23 installed on the side walls of at least two sides. When the mold bar 102 is located below the mounting shell 2, the rotating part 3042 is installed with clamping blocks 23 on one side facing the mold bar 102 and on the opposite side of the side. When one of the clamping blocks 23 is worn, the rotating part 3042 is rotated 180° so that the other clamping block 23 is put into use, so that the service life of one clamp 304 in normal use is doubled, thereby increasing the practicality of the device and reducing its replacement frequency.

[0066] A limiting plate 3043 is hinged on the base 3041, and a limited rotation rod 3044 is installed on the limiting plate 3043. A C-shaped groove 3045 for accommodating the limited rotation rod 3044 is opened on the clamping block 23. The rotation direction of the limiting plate 3043 is perpendicular to the rotation direction of the rotating part 3042. When the clamping block 23 is in normal use, the limiting plate 3043 is rotated so that the limited rotation rod 3044 is inserted into the C-shaped groove 3045, and the inner wall of the C-shaped groove 3045 is restricted by the side wall of the limited rotation rod 3044, so that the rotation of the rotating part 3042 is restricted, thereby increasing the stability of the clamping block 23 when in use. When the spare clamping block 23 needs to be replaced, the limiting plate 3043 is rotated to separate the limited rotation rod 3044 from the C-shaped groove 3045 and then rotate it, thereby increasing the practicality of the device.

[0067] The clamping block 23 is sleeved with a rubber sleeve 21 , and the clamping block 23 contacts the bottle cap through the rubber sleeve 21 . The clamping block 23 flexibly contacts the bottle cap through the rubber sleeve 21 , thereby reducing the possibility of damaging the bottle cap when clamping the bottle cap.

[0068] In embodiment three, a round rod 19 is installed on the mounting shell 2, and a baffle 20 is installed on the free end of the round rod 19. The round rod 19 is slidably matched with the body shell 1. A plate body is installed on the body shell 1. The round rod 19 penetrates the plate body and is slidably matched with the body shell 1, and a hole is formed on the plate body. The diameter of the baffle 20 is larger than the diameter of the hole. When the mounting shell 2 slides, it drives the round rod 19 to slide, and the inner wall of the hole restricts the side wall of the round rod 19, so that the mounting shell 2 can only slide on the body shell 1 in the vertical direction, and when the mounting shell 2 slides to the point where the baffle 20 conflicts with the plate body on the body shell 1, that is, the sliding of the mounting shell 2 reaches the maximum value, so that when the mounting shell 2 slides to the maximum limit, the conflict between the baffle 20 and the plate body can stop more stably, so that the airflow can subsequently blow the baffle 6 better.

[0069] In the third embodiment, a camera 25 is installed on the body shell 1, and the camera 25 is facing the mold bar 102 that contacts the sleeve. The camera 25 is installed on the body shell 1 and is located at the conveyor belt used for loading materials. The camera 25 is used to detect the sleeve to be transported to the mold bar 102, and monitor and detect whether it is aligned with the mold bar 102, whether it is in contact with the mold bar 102, and whether there are stains on it. This is convenient for increasing the fit between the sleeve and the mold bar 102 when connected, and is also convenient for selecting and removing the sleeve with stains and contamination, thereby increasing the practicality of the device.

[0070] In embodiment three, a contact ball 22 is installed at the end of the sliding rod 307 facing the accommodating chamber 10, and the sliding rod 307 contacts the inner wall of the accommodating chamber 10 through the contact ball 22. When the contact ball 22 collides with the inner wall of the accommodating chamber 10, the arc surface of the contact ball 22 contacts and guides the inner wall of the accommodating chamber 10 more smoothly, thereby reducing the wear between the sliding rod 307 and the inner wall of the accommodating chamber 10 and increasing the practicality of the device.

[0071] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
