Abstract
Description
Technical Field
[0001] This utility model relates to the field of beverage filling production equipment, specifically to an active compatible bottle clamp for transferring containers. Background Technology
[0002] The ever-changing market demands have led to increasing product differentiation. Different bottle models have different diameters, and when switching products, the blow-fill-seal equipment requires changing the bottle clamps to match the new product, while ensuring that the center position of the clamps remains unchanged. Because the entire production line has many bottle clamps and a complex structure, manual replacement and adjustment are time-consuming and labor-intensive, resulting in long downtimes, significantly impacting production efficiency and causing inconvenience to customers. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide an active compatibility bottle clamp that can be compatible with two different bottle mouth shapes.
[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: an active compatible bottle clamp, comprising: a base plate, on which two clamping pieces are provided, the rear ends of the two clamping pieces being hinged to the base plate respectively, so that the two clamping pieces can clamp left and right, and clamping heads are provided on the front ends of the two clamping pieces. The characteristic feature is that: two driving arms, a driving shaft, a roller, and a swing arm are provided behind the two clamping pieces; the front ends of the two driving arms are fixed to the rear ends of the two clamping pieces respectively; the rear ends of the two driving arms are stacked vertically; motion curve grooves are provided on the rear ends of both driving arms; the lower end of the driving shaft passes through the two motion curve grooves; a vertical shaft is fixed on the base plate on one side of the driving shaft; and the swing arm is located vertically... Between the shaft and the drive shaft, the outer end of the swing arm is hinged to the base plate via a vertical shaft, allowing the swing arm to swing horizontally back and forth. The inner end of the swing arm is fixed to the drive shaft, and the roller is rotatably mounted on the drive shaft. When the drive shaft is driven to swing forward, it can drive two clamping plates to open synchronously by cooperating with two motion curve grooves. When the drive shaft is driven to swing backward, it can drive two clamping plates to clamp synchronously by cooperating with two motion curve grooves. Clamping surfaces are provided on the inner sides of the front of the two clamping plates, and a slider and a rear stop are provided between the two clamping plates. A sliding groove is provided on the base plate, and the slider is located in the sliding groove and can slide back and forth along the sliding groove. A front stop is provided at the front end of the sliding groove to block the slider. A spring seat is located at the rear end of the slide rail, and a spring is placed between the spring seat and the slider. Under the push of the spring, the slider slides forward until it abuts against the front stop. A clearance notch is provided on the upper rear part of the slider to allow the two drive arms to pass. A front clamping part and a rear abutment surface are located on the upper front side of the slider. The rear abutment surface is located behind the front clamping part, and the rear stop is located behind the rear abutment surface and fixed to the base plate. When the slider slides backward, the rear stop allows the rear abutment surface to abut against it, thus limiting the slider's rear movement. The left and right sides of the slider allow corresponding clamping surfaces to abut against it, limiting the clamping angle of the two clamping plates. A torsion spring is fitted on the vertical shaft between the outer end of the swing arm and the base plate. The lower end of the torsion spring is fixed to the base plate, and the upper end of the torsion spring is connected to the outer end of the swing arm. Fixed, under the action of the torsion spring, the swing arm drives the drive shaft to swing backward until the two clamping plates clamp together and their respective clamping surfaces abut against the sides of the slider. After the roller rolls on the cam, it can make the drive shaft overcome the torsion spring torque and swing forward. At this time, the two clamping plates will be driven to open to facilitate the bottle insertion. After the roller and the cam are separated, the two clamps can clamp the bottle mouth under the action of the torsion spring. When clamping the bottle mouth of the small bottle, the two clamps will clamp together at the position where the clamping surfaces of the two clamping plates abut against the sides of the slider. The front clamp will be pressed by the bottle mouth of the small bottle and press the bottle mouth of the small bottle tightly between the two clamps. At this time, the center of the bottle mouth of the small bottle can be positioned at the clamping center point O under the clamping of the two clamps and the front clamp.When the large bottle neck is clamped, the bottle neck will move inward under the clamping of the two clamps, pressing down on the front clamp until the front clamp is pressed down to the position where the rear surface abuts against the rear stop. At this point, the center of the large bottle neck can be positioned at the clamping center point O under the clamping of the two clamps and the front clamp.
[0005] Furthermore, in the aforementioned active compatible bottle clamp, a wear-resistant sliding plate is also provided. An installation groove is provided on the bottom surface of the slider. The top of the sliding plate is installed in the installation groove, so that the sliding plate can slide together with the slider. The bottom of the sliding plate is placed between the slider and the bottom of the groove, so that the slider can slide smoothly.
[0006] Furthermore, in the aforementioned active compatible bottle clamp, the spring seat is detachably mounted in the rear end of the slide by screws.
[0007] Furthermore, in the aforementioned active compatible bottle clamp, a sleeve is provided on the outer end of the swing arm, and flange bearings are respectively installed at the upper and lower ends of the sleeve. The sleeve is smoothly rotatably mounted on the vertical shaft through the two flange bearings, and a cap-type nut is threadedly connected to the top of the vertical shaft.
[0008] Furthermore, in the aforementioned active compatible bottle clamp, a wear-resistant sleeve is fitted and fixed on the lower end of the drive shaft that passes through two motion curve grooves.
[0009] Furthermore, in the aforementioned active compatible bottle clamp, a baffle plate is also provided to block the upper limit of the slider above the slider. The baffle plate is fixed to the base plate by connecting its two ends to the top of the hinge shafts of the two clamping plates respectively. The front end face of the baffle plate serves as the rear stop, and the rear end face of the front clamp serves as the rear support surface.
[0010] Furthermore, in the aforementioned active compatible bottle clamp, a mounting post is provided on each of the left and right sides below the base plate, the top of the mounting post is fixed to the base plate, and the bottom of the mounting post is used to fix it to the rotating disk.
[0011] The advantages of this utility model are as follows: the active compatible bottle clamp can clamp and position the bottle mouth of small bottles and large bottles at the same clamping center point O by using two clamps that can be opened and closed to a specific position and a front clamp that can slide back and forth to a specific position. This ensures that the junction center between the bottle clamps remains unchanged regardless of whether a large or small bottle is clamped. Thus, the bottle clamps can work normally without changing them when switching between small and large bottle beverage production. Attached Figure Description

[0017] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.
[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, an active compatible bottle clamp includes: a base plate 1, on which two clamping pieces 2 are disposed, the rear ends of which are hinged to the base plate 1 respectively, allowing the two clamping pieces 2 to clamp from left to right; the front ends of the two clamping pieces 2 are provided with clamping heads 3 for clamping bottle necks, and the clamping center O of the bottle clamp is located between the two clamping heads 3; behind the two clamping pieces 2 are two driving arms 4, a driving shaft 5, a roller 9, and a swing arm 6; the front ends of the two driving arms 4 are fixed to the rear ends of the two clamping pieces 2 respectively, and the rear ends of the two driving arms 4 are stacked vertically; each of the rear ends of the two driving arms 4 is provided with a motion curve groove 7; the lower end of the driving shaft 5 passes through the two motion curve grooves 7; a vertical shaft 8 is fixed on the base plate 1 on one side of the driving shaft 5; and the swing arm 6 is positioned... Between the vertical shaft 8 and the drive shaft 5, the outer end of the swing arm 6 is hinged to the base plate 1 with the vertical shaft 8 as the hinge axis, so that the swing arm 6 can swing horizontally back and forth. The inner end of the swing arm 6 is fixed to the drive shaft 5. The roller 9 is rotatably mounted on the drive shaft 5. When the drive shaft 5 is driven to swing forward, it can drive the two clamping plates 2 to open synchronously by cooperating with the two motion curve grooves 7. When the drive shaft 5 is driven to swing backward, it can drive the two clamping plates 2 to clamp synchronously by cooperating with the two motion curve grooves 7. Clamping surfaces 10 are respectively provided on the inner side of the front part of the two clamping plates 2. A slider 11 and a rear stop 12 are provided between the two clamping plates 2. A sliding groove 13 is provided on the base plate 1. The slider 11 is located in the sliding groove 13 and can slide back and forth along the sliding groove 13. A front stop 14 is provided at the end of the slide 11 to block the slider 11. A spring seat 15 is provided at the rear end of the slide groove 13. A spring 16 is provided between the spring seat 15 and the slider 11. Under the push of the spring 16, the slider 11 slides forward until it abuts against the front stop 14. When the two clamps 2 open, the two drive arms 4 will approach each other. Therefore, a clearance notch 17 is provided at the upper rear part of the slider 11 to avoid the two drive arms 4. A front clamp 18 and a rear abutment surface 19 are provided on the upper front side of the slider 11. The rear abutment surface 19 is located behind the front clamp 18. The rear stop 12 is located behind the rear abutment surface 19 and is fixed to the base plate 1. When the slider 11 slides backward, the rear stop 12 allows the rear abutment surface 19 to abut against it to limit the slider 11 to the rear. The left and right sides of the slider 11 The corresponding clamping surfaces 10 can be used to abut against each other to limit the clamping angle of the two clamping pieces 2. A torsion spring 20 is fitted on the vertical shaft 8 between the outer end of the swing arm 6 and the base plate 1. The lower end of the torsion spring 20 is inserted into the base plate 1, and the upper end of the torsion spring 20 is inserted into the outer end of the swing arm 6. Under the action of the torsion spring 20, the swing arm 6 drives the drive shaft 5 to swing backward until the two clamping pieces 2 are clamped together and their respective clamping surfaces 10 abut against the sides of the slider 11. As the rotating disk rotates with the bottle clamp, the roller 9 rolls on the cam of the blow-fill-spinning device, which enables the drive shaft 5 to overcome the torque of the torsion spring 20 and swing forward. At this time, the two clamping pieces 2 will be driven to open to facilitate bottle insertion. After the roller 9 disengages from the cam, the two clamps 3 can clamp the bottle mouth under the action of the torsion spring 20. When clamping the bottle mouth 25 of the small bottle,The two clamps 3 clamp the two clamping surfaces 10 of the two clamping plates 2 to abut against the sides of the slider 11. The front clamp 18 is pressed by the bottle opening 25, pressing the bottle opening 25 tightly between the two clamps 3. At this time, the center of the bottle opening 25 can be positioned at the clamping center O point under the clamping of the two clamps 3 and the front clamp 18. When clamping the bottle opening 26, the bottle opening 26 will move inward under the clamping of the two clamps 3, pressing the front clamp 18 until the front clamp 18 is pressed to the position where the rear abutment surface 19 abuts against the rear stop 12. At this time, the center of the bottle opening 26 can be positioned at the clamping center O point under the clamping of the two clamps 3 and the front clamp 18.
[0019] With the above settings, the bottle clamps can ensure that the center position of the intersection between the bottle clamps remains unchanged regardless of whether they are clamping large or small bottles. This way, production can proceed normally without changing the bottle clamps when switching between small and large bottle beverage production.
[0020] In this embodiment, a wear-resistant slide plate 21 is also provided. A mounting groove is provided on the bottom surface of the slider 11, and the top of the slide plate 21 is installed in the mounting groove, allowing the slide plate 21 to slide together with the slider 11. The bottom of the slide plate 21 is placed between the slider 11 and the bottom of the slide groove 13, allowing the slider 11 to slide smoothly. The spring seat 15 is detachably installed in the rear end of the slide groove 13 by screws. A sleeve is provided on the outer end of the swing arm 6, and flange bearings are respectively installed at the upper and lower ends of the sleeve. The sleeve is smoothly rotatably fitted onto the vertical shaft 8 through the two flange bearings. A cap nut 22 is threadedly connected to the top of the vertical shaft 8. A wear-resistant sleeve is fitted and fixed on the lower end of the drive shaft 5, which passes through the two motion curve grooves 7, to prevent wear on the lower end of the drive shaft 5. A baffle 23 is also provided to limit the movement of the slider 11 from above. The baffle 23 is fixed to the base plate 1 by connecting its two ends to the top of the hinge shafts of the two clamping pieces 2. The front end of the baffle 23 serves as a rear abutment 12, and the rear end of the front clamping part 18 serves as a rear abutment surface 19. A mounting post 24 is provided on each of the left and right sides below the base plate 1. The top of the mounting post 24 is fixed to the base plate 1, and the bottom of the mounting post 24 is used to fix it to the rotating disk. After the bottle clamp is suspended on the rotating disk by the two mounting posts 24, the assembly gaps and installation contact surfaces are greatly reduced, thereby reducing cleaning dead corners. This better meets the customer's requirements for the cleanliness of sterile equipment, while also reducing the number of installation parts, simplifying the structure, and extending the service life.
