[0002] Most common condiments in people's lives, such as soy sauce, vinegar, and cooking wine, are packaged in glass bottles. Existing production lines usually use automatic conveyor lines to transport and transfer glass bottles. In order to prevent the glass bottles from tipping over and to make the transfer of glass bottles more stable, the existing conveyor lines will hold the glass bottles upright with the bottom facing down when transporting them. Although this type of conveyor line ensures the stability of glass bottle transport, it has the following problems: (1) With the bottle mouth facing upwards, there is a risk of debris falling in during the transfer process on the conveyor line; (2) During the washing or drying process, the moisture and impurities inside the upright glass bottles are not easily discharged. Summary of the Invention

A pull rod is coaxially arranged inside the circular tube. The front end of the pull rod is connected to the outer pressure plate through a connecting rod. The pull rod is movable along the axis. A positioning plate is provided at the rear end of the pull rod. When the end face of the positioning plate contacts the limiting plate, both the inner and outer pressure plates are parallel to the limiting plate. When the positioning plate contacts the convex strip, the distance between the inner and outer pressure plates is the smallest. When the positioning plate contacts the side wall of the track, the distance between the inner and outer pressure plates is the largest.
[0008] The rotating mechanism includes a rotating shaft for connecting the positioning plate and driving the pull rod to rotate around the axis, and the rotating shaft is set to reciprocate within the length range of the notch.
[0009] Furthermore, a strip-shaped hole is provided at one end of the round tube near the inner pressure plate. The strip-shaped hole is provided at both ends of the inner pressure plate. The connecting rod includes guide rods at both ends of the outer pressure plate. The ends of the guide rods are connected by a crossbar, and the crossbar passes through the strip-shaped hole. The middle section of the crossbar is connected to the front end of the pull rod.
[0010] Furthermore, a spring is provided between the crossbar and the slider, and the spring is sleeved on the outside of the circular tube.
[0011] Furthermore, the axis of the rotating shaft and the axis of the pull rod are at the same distance from the limiting plate, and the rotating shaft is perpendicular to the side wall of the track. A rectangular plate is vertically provided at the front end of the rotating shaft, and a through groove that mates with the rectangular plate is provided in the middle of the outer wall of the positioning plate. When the positioning plate contacts the protrusion and the end face of the positioning plate contacts the limiting plate, the rectangular plate is aligned with the through groove.
[0012] Furthermore, the upper and lower ends of the positioning plate are provided with side rollers that are symmetrical with respect to the axis of the pull rod. The side rollers are used to contact the side wall and the protrusion of the track.
[0013] Furthermore, the rotating mechanism includes a slide rail parallel to one side of the notch, a motor slidably mounted on the slide rail, a rotating shaft coaxially mounted at the front end of the motor's main shaft, and a telescopic device at one end of the slide rail, the movable rod of the telescopic device being connected to the motor.
[0014] Furthermore, the track has a U-shaped cross-section with a T-groove on its top surface. The lower end of the slider slides within the T-groove, and the projection of the lower end of the slider onto the bottom surface of the T-groove is a spindle-shaped structure.
[0015] Furthermore, two intermediate rollers are coaxially arranged on both sides of the lower middle part of the slider, and an end roller is provided at each end of the lower end of the slider. The intermediate rollers are rolled in the grooves on both sides of the T-slot, and the end rollers are located in the middle position in the width direction of the T-slot.

Multiple sliders are arranged in an array along the ring track on the track, and each slider is provided with a clamping component. A pin is provided on the top of the slider, and the pin is coaxially arranged with the pin shaft of the ring chain. The protrusion and the limiting plate are located on the inner side of the ring of the track, and the inner pressure plate and the outer pressure plate are located on the outer side of the ring of the track.
[0017] Furthermore, the convex strip has at least one front inclined surface and one rear inclined surface, both of which intersect with the side wall of the track. The front inclined surface faces the direction of movement of the slider and the inner ring of the track, while the rear inclined surface faces the inner ring of the slider track and is opposite to the direction of movement of the slider. In the direction of movement of the slider, the rear inclined surface is located in front of the front inclined surface, and the notch is located below the convex strip.
[0018] The beneficial effects of this invention are as follows:
[0019] 1. The condiment bottle transfer mechanism of this application can transport condiment bottles in an inverted state, which not only makes it easier to drain liquid and impurities during the cleaning process, but also prevents debris from falling into the bottle during the transport process.

Detailed Implementation
[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention will be described in detail below with reference to the accompanying drawings. However, the embodiments described in this invention are only some embodiments of the present invention, and not all embodiments.
[0034] Example 1
[0035] A condiment bottle transfer mechanism includes: a track 1, a clamping assembly 2, and a rotating mechanism 3.
[0036] Specifically, such as Figure 1 , Figure 2 As shown, a slider 11 is movable on the track 1, and a protrusion 12 of a predetermined length is provided parallel to one side of the outer wall of the track 1. A limiting plate 13 is also provided below the protrusion 12 on the track 1. A notch 131 is provided on the limiting plate 13 along a predetermined range in the length direction, and the notch 131 is located below the protrusion 12.
[0037] Specifically, such as Figures 1 to 5 As shown, the clamping assembly 2 includes an inner pressure plate 21 and an outer pressure plate 22 arranged in parallel. The inner pressure plate 21 and the outer pressure plate 22 each have a V-shaped groove on their opposite sides. A circular tube 211 is vertically arranged on the outer side of the inner pressure plate 21. The circular tube 211 passes through the slider 11. The inner pressure plate 21 and the outer pressure plate 22 are located on the other side of the track 1 relative to the protrusion 12. The distance between the inner pressure plate 21 and the slider 11 is constant. A pull rod 23 is coaxially arranged inside the circular tube 211. The front end of the pull rod 23 is connected to the outer pressure plate 22 through a connecting rod 24. The pull rod 23 is movable along the axis. A positioning plate 25 is provided at the rear end of the pull rod 23.
[0038] like Figure 2 As shown, when the end face of the positioning plate 25 slides into contact with the top surface of the limiting plate 13, both the inner pressure plate 21 and the outer pressure plate 22 are parallel to the limiting plate 13. Figure 1 , Figure 2As shown, when the inner side of the positioning plate 25 contacts the outer wall of the protrusion 12, the distance between the inner pressure plate 21 and the outer pressure plate 22 is at its minimum. This state is used to clamp the condiment bottle. Figure 9 As shown, when the inner side of the positioning plate 25 contacts the side wall of the track 1, the distance between the inner pressure plate 21 and the outer pressure plate 22 is at its maximum. This state is used to remove or insert the condiment bottle between the inner pressure plate 21 and the outer pressure plate 22.
[0039] like Figure 1 , Figure 2 As shown, the rotating mechanism 3 includes a rotating shaft 31 perpendicular to the side wall of the track 1. The rotating shaft 31 is used to connect the positioning plate 25 and drive the pull rod 23 to rotate around the axis. Specifically, the rotating shaft 31 can be connected to the positioning plate 25 by magnetic attraction or hole-shaft connection. The cross-section of the hole-shaft is a non-circular structure, such as polygonal or elliptical, so as to drive the pull rod 23 to rotate through the rotating shaft 31. The rotating shaft 31 is reciprocated within the length range of the notch 131 so that the rotation work can be completed during the movement of the slider 11, avoiding the slider 11 from stopping and maintaining the conveying rhythm.
[0040] When using, in such Figure 9 In the indicated state, the inner side of the positioning plate 25 contacts the side wall of the track 1, and the distance between the inner pressure plate 21 and the outer pressure plate 22 is at its maximum. At this point, the neck of the condiment bottle is placed between the inner pressure plate 21 and the outer pressure plate 22, and the condiment bottle is inverted. The V-groove of the inner pressure plate 21 and the outer pressure plate 22 serves as a limit for the condiment bottle. The slider 11 moves within the track 1, during which the positioning plate 25 gradually transitions from the side wall of the track 1 to the protrusion 12. The protrusion distance between the protrusion 12 and the side wall of the track 1, and the positioning plate... 25 drives the pull rod 23 to move towards the protrusion 12, thereby causing the outer pressure plate 22 to move closer to the inner pressure plate 21, so that the outer pressure plate 22 and the inner pressure plate 21 press the neck of the condiment bottle tightly. During the movement of the slider 11, the positioning plate 25 remains in contact with the protrusion 12 to ensure continuous pressure on the condiment bottle and prevent it from falling during transport. The inverted transport position of the condiment bottle not only facilitates the drainage of liquid and impurities during the cleaning process but also prevents debris from falling into the bottle during transport. To improve clamping stability and prevent crushing of the condiment bottle, rubber pads can be laid in the V-grooves of the outer pressure plate 22 and the inner pressure plate 21.
[0041] like Figure 1 , Figure 2As shown, after the rotating shaft 31 is connected to the positioning plate 25, the rotating shaft 31 will move together with the positioning plate 25 and the slider 11. When the positioning plate 25 moves to the range of the notch 131, the rotating shaft 31 can drive the positioning plate 25 to rotate, thereby driving the inner pressure plate 21 and the outer pressure plate 22 to rotate 180° around the pull rod 23, thus flipping the condiment bottle into an upright position for subsequent filling. During this process, the positioning plate 25 always maintains contact with the protrusion 12, so that the inner pressure plate 21 and the outer pressure plate 22 always maintain a clamping state on the condiment bottle. After the condiment bottle is upright, as the positioning plate 25 gradually moves from the outer wall of the protrusion 12 to the side wall of the track 1, the pull rod 23 will move towards the other side of the track 1, causing the outer pressure plate 22 to move away from the inner pressure plate 21, thereby releasing the condiment bottle.
[0042] Preferred, such as Figure 4 , Figure 5 As shown, a strip-shaped hole 212 is provided at one end of the circular tube 211 near the inner pressure plate 21. The strip-shaped hole 212 is provided at both ends of the inner pressure plate 21. The connecting rod 24 includes guide rods 241 at both ends of the outer pressure plate 22. The ends of the guide rods 241 are connected by a crossbar 242, and the crossbar 242 passes through the strip-shaped hole 212. The middle section of the crossbar 242 is connected to the front end of the pull rod 23. This structure not only ensures the stability of the relative position of the outer pressure plate 22 and the inner pressure plate 21, keeping them on the same plane, but also allows the outer pressure plate 22 and the inner pressure plate 21 to rotate simultaneously via the pull rod 23, thereby achieving the flipping operation of the condiment bottle. The crossbar 242 adopts a through-mount installation structure. During assembly, the crossbar 242 passes through the guide rod 241, the strip-shaped hole 212, and the pull rod 23.
[0043] More specifically, such as Figure 3 , Figure 4 As shown, a spring 26 is provided between the crossbar 242 and the slider 11, and the spring 26 is sleeved on the outside of the round tube 211 to maintain the stability of the spring 26. The spring 26 is in a compressed state, and the spring 26 pushes the outer pressure plate 22 away from the inner pressure plate 21. Thus, when the positioning plate 25 is separated from the protrusion 12, the positioning plate 25 is kept in close contact with the side wall of the track 1, thereby maintaining the maximum distance between the outer pressure plate 22 and the inner pressure plate 21.
[0044] Preferred, such as Figures 1 to 4As shown, the distance between the axis of the rotating shaft 31 and the axis of the pull rod 23 and the limiting plate 13 is the same, that is, the rotating shaft 31 and the pull rod 23 are in the same plane, and this plane is parallel to the limiting plate 13. The rotating shaft 31 is perpendicular to the side wall of the track 1. A rectangular plate 311 is vertically provided at the front end of the rotating shaft 31. A through groove 251 that mates with the rectangular plate 311 is opened on both sides of the middle of the outer wall of the positioning plate 25. When the positioning plate 25 contacts the protrusion 12 and the end face of the positioning plate 25 contacts the limiting plate 13, the rectangular plate 311 is aligned with the through groove 251. When the slider 11 moves close to the notch 13... When at the end position, the rectangular plate 311 is inserted into the through groove 251, and then the rotating shaft 31 moves together with the slider 11 in the notch 131. Because of the notch 131, the end face of the positioning plate 25 separates from the limiting plate 13 during the movement of the slider 11 within the range of the notch 131, so that the rotation of the rotating shaft 31 can drive the pull rod 23 to rotate, and then drive the inner pressure plate 21 and the outer pressure plate 22 to rotate together, thereby realizing the flipping of the condiment bottle. The rotating shaft 31 can rotate 180 degrees to turn the upright condiment bottle into an inverted state, and can also turn the inverted condiment bottle into an upright state.
[0045] Preferred, such as Figures 2 to 5 and Figure 8 , Figure 9 As shown, the upper and lower ends of the positioning plate 25 are provided with side rollers 252 that are symmetrical with respect to the axis of the pull rod 23. The side rollers 252 are used to contact the side wall of the track 1 and the protrusion 12 to reduce the friction between the positioning plate 25 and the track 1 and the protrusion 12, and to make the slider 11 move more smoothly.
[0046] More specifically, such as Figure 1 As shown, the rotating mechanism 3 includes a slide rail 32 parallel to one side of the notch 131. A motor 33 is slidably mounted on the slide rail 32. The rotating shaft 31 is coaxially mounted at the front end of the main shaft of the motor 33. One end of the slide rail 32 is provided with a telescopic device 34. The movable rod of the telescopic device 34 is connected to the motor 33 and is used to drive the motor 33 to reciprocate along the slide rail 32 so as to realize the purpose of reciprocating the rotating shaft 31 along the length range of the notch 131.
[0047] Preferred, such as Figure 3 As shown, the cross-section of the track 1 is U-shaped, and its top surface has a T-shaped groove 101. The lower end of the slider 11 is slidably disposed in the T-shaped groove 101, and the projection of the lower end of the slider 11 on the bottom surface of the T-shaped groove 101 is a spindle structure to adapt to the rounded corner structure at the corner of the track 1, so that the track 1 can adopt a ring structure.
[0048] Further preferred, such as Figure 4As shown, two intermediate rollers 111 are coaxially arranged on both sides of the lower middle part of the slider 11, and an end roller 112 is provided at each end of the lower end of the slider 11. The intermediate rollers 111 are rolled in the grooves on both sides of the T-slot 101 to realize the connection between the slider 11 and the T-slot 101, prevent the slider 11 from falling out of the T-slot 101, and maintain the position of the slider 11 in the width direction of the T-slot 101. The end rollers 112 are located in the middle of the width direction of the T-slot 101. The end rollers 112 are used to maintain the balance of the slider 11 so that the slider 11 slides smoothly in the T-slot 101. The arrangement structure of the end rollers 112 can adapt to the angle change of the track 1, so that the track 1 can have more diverse structures.
[0049] Example 2
[0050] like Figures 1 to 7 As shown, a condiment bottle conveying device includes the condiment bottle transfer mechanism described in Embodiment 1. The track 1 has a ring structure, and a ring chain 4 that coincides with its track is provided above it. The ring chain 4 is driven by a motor to drive a sprocket. Multiple sliders 11 are arranged along the ring track on the track 1, and each slider 11 is provided with a clamping component 2. The top of the slider 11 is provided with a pin 113. The pin 113 is coaxially arranged with the pin shaft of the ring chain 4. In application, the pin 113 can be directly used as part of the pin shaft of the ring chain 4. The protrusion 12 and the limiting plate 13 are located on the inner side of the ring of the track 1, and the inner pressure plate 21 and the outer pressure plate 22 are located on the outer side of the ring of the track 1.
[0051] Preferred, such as Figures 6 to 9As shown, the protrusion 12 has at least one front inclined surface 121 and one rear inclined surface 122. Both the front inclined surface 121 and the rear inclined surface 122 intersect the side wall of the track 1 to ensure that the positioning plate 25 smoothly transitions between the outer wall of the protrusion 12 and the side wall of the track 1. The front inclined surface 121 faces the moving direction of the slider 11 and the annular interior of the track 1, while the rear inclined surface 122 faces the annular interior of the track 1 and is opposite to the moving direction of the slider 11. In the moving direction of the slider 11, the rear inclined surface 122 is located in front of the front inclined surface 121, and the notch 131 is located in front of the protrusion 122. Below the strip 12, the notch 131 is located within the solid area of the protruding strip 12 to ensure that the inner pressure plate 21 and the outer pressure plate 22 remain in a closed clamping state during the rotation of the pull rod 23. When the positioning plate 25 moves from the protruding strip 12 across the front inclined surface 121 toward the side wall of the track 1, the outer pressure plate 22 moves toward the outside of the track 1, thereby releasing the condiment bottle. In practical applications, a receiving groove 5 is set on the outside of the track 1 corresponding to the front inclined surface 121 and the predetermined range behind it to receive and transport the condiment bottle that is upright after being flipped 180°. When the positioning plate 25 moves from the side wall of the track 1 past the inclined surface 122 toward the convex strip 12, the outer pressure plate 22 moves toward the inside of the track 1. This process can be used for feeding. The outer pressure plate 22 clamps the condiment bottle, and then the slider 11 carries the condiment bottle along the track 1 for conveying. A section of the track 1 can be set in the cleaning equipment, so that the condiment bottle can be inverted and tilted. After cleaning, the condiment bottle can be flipped over by the rotating mechanism 3 so that the condiment bottle is conveyed in an upright state.
