Abstract
Description
Technical Field
[0001] This utility model relates to the field of filling production equipment, specifically to a compatible bottle clamp for transferring containers. Background Technology
[0002] Market demand has led to increasing product differentiation, with different bottle sizes having varying mouth diameters. This makes it difficult for blow-fill-seal equipment to quickly switch products. Switching products requires replacing the bottle clamps with specialized ones that match the new product, while ensuring the clamp's center position remains unchanged. The numerous and complex bottle clamps in the blow-fill-seal system result in time-consuming, labor-intensive disassembly, installation, and debugging, leading to significant downtime, production disruptions, and increased filling costs. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a compatible bottle clamp that can accommodate two different bottle mouth shapes.
[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: a compatible bottle clamp, comprising: a base plate, on which two clamping pieces are provided, the middle parts of the two clamping pieces being hinged to the base plate respectively, so that the two clamping pieces can clamp each other from left to right, and clamping heads for clamping bottle mouths are provided on the front ends of the two clamping pieces, and a clamping drive mechanism for driving the two clamping pieces to clamp bottle mouths is provided on the base plate behind the two clamping pieces, characterized in that: a connecting rod is provided on the front part of each of the two clamping pieces, and the rear ends of the clamping heads of the two clamping pieces are connected to the base plate. A positioning block is set between the two parts, and two connecting rods are arranged in a figure-eight shape. The front ends of the two connecting rods are hinged to the left and right sides of the positioning block, respectively, and the rear ends of the two connecting rods are hinged to the outer side of the corresponding clamping piece. When the two clamping pieces clamp the bottle mouth, they can drive the positioning block to move forward through the two connecting rods, so that the bottle mouth can be positioned back and forth by abutting against the positioning block. The distance that the positioning block is driven forward will increase as the bottle mouth shrinks, so that when the small bottle mouth and the large bottle mouth are clamped, the center of the two can be positioned at the same position.
[0005] Furthermore, in the aforementioned compatible bottle clamp, the front end face of the positioning block is provided with a small arc segment that can be adapted to the mouth of a small bottle and a large arc segment that can be adapted to the mouth of a large bottle.
[0006] Furthermore, in the aforementioned compatible bottle clamp, the large arc segment consists of two parts, and the small arc segment is located between the two parts of the large arc segment.
[0007] Furthermore, in the aforementioned compatible bottle clamp, a guide rod and a limiting plate are provided behind the positioning block. The limiting plate is fixed to the base plate. When the two clamps are opened, the positioning block moves backward under the drive of the two connecting rods. The limiting plate can limit the distance the positioning block moves backward, thereby preventing the positioning block from crossing the dead point position. A guide groove is provided on the limiting plate, and the guide rod is located in the guide groove. The front end of the guide rod is fixed to the positioning block. After the guide rod and the guide groove cooperate, they can guide the forward and backward movement of the positioning block.
[0008] Furthermore, in the aforementioned compatible bottle clamp, the clamping drive mechanism comprises two drive arms, a drive shaft, a roller, and a rocker arm. The front ends of the two drive arms are fixed to the rear ends of the two clamping pieces, and the rear ends of the two drive arms are stacked vertically. A motion curve groove is provided on the rear ends of both drive arms. The lower end of the drive shaft passes through the two motion curve grooves. One end of the rocker arm is hinged to the base plate, and the other end of the rocker arm is fixed to the drive shaft, allowing the drive shaft to swing under the constraint of the rocker arm. The roller is rotatably mounted on the upper end of the drive shaft. The cam can drive the drive shaft to swing by rolling on the roller. After the drive shaft swings, it can drive the two clamping pieces to clamp or open synchronously by cooperating with the two motion curve grooves.
[0009] The advantages of this utility model are as follows: When the two clamping pieces in the compatible bottle clamp clamp the bottle mouth, the positioning block can be driven to move forward through two connecting rods, so that the bottle mouth can be positioned back and forth by abutting against the positioning block. The distance that the positioning block is driven forward will increase as the bottle mouth shrinks, so that when the small bottle mouth and the large bottle mouth are clamped, the center of both can be positioned at the same position. This ensures that the center position of the intersection between the bottle clamps remains unchanged regardless of whether a large or small bottle is clamped. Thus, when switching between small and large bottle beverage production, normal production can be carried out without changing the bottle clamps. Attached Figure Description

[0014] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.
[0015] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a compatible bottle clamp includes: a base plate 1, on which two clamping pieces 2 are disposed, the middle portions of which are respectively hinged to the base plate 1, allowing the two clamping pieces 2 to clamp each other from left to right; clamping heads 3 for clamping bottle necks are disposed at the front ends of the two clamping pieces 2; a clamping drive mechanism for driving the two clamping pieces 2 to clamp bottle necks is disposed on the base plate 1 behind the two clamping pieces 2; a connecting rod 4 is disposed at the front of each of the two clamping pieces 2; a positioning block 5 is disposed between the rear ends of the clamping heads 3 of the two clamping pieces; the two connecting rods 4 are arranged in a V-shape, and the front ends of the two connecting rods 4 are respectively connected to the left and right sides of the positioning block 5. The two connecting rods 4 are hinged to the outer sides of their respective clamping pieces 2. When the two clamping pieces 2 clamp the bottle mouth, they can drive the positioning block 5 to move forward through the two connecting rods 4. This allows the bottle mouth to be positioned back and forth by abutting against the positioning block 5. The distance that the positioning block 5 is driven forward increases as the bottle mouth shrinks, so that when the small bottle mouth and the large bottle mouth are clamped, the center of their circles can be positioned at the same position. This ensures that the center position of the intersection between the bottle clamps remains unchanged regardless of whether a large or small bottle is clamped. This allows for normal production without changing the bottle clamps when switching between small and large bottle beverage production.
[0016] In this embodiment, the front end face of the positioning block 5 is provided with a small arc segment 6 that can fit the mouth of a small bottle and a large arc segment 7 that can fit the mouth of a large bottle. The large arc segment 7 consists of two segments, and the small arc segment 6 is located between the two segments of the large arc segment 7. This arrangement is for better positioning of bottle mouths of different sizes.
[0017] A guide rod 8 and a limiting plate 9 are provided behind the positioning block 5. The limiting plate 9 is fixed to the base plate 1. When the two clamping pieces 2 are opened, the positioning block 5 will move backward under the drive of the two connecting rods 4. The limiting plate 9 can limit the distance the positioning block 5 moves backward, thereby preventing the positioning block 5 from crossing the dead point. After the positioning block 5 crosses the dead point, the two clamping pieces 2 will not be able to drive the positioning block 5 to move forward. A guide groove 10 is provided on the limiting plate 9, and the guide rod 8 is located in the guide groove 10. The front end of the guide rod 8 is fixed to the positioning block 5. The guide rod 8 and the guide groove 10 cooperate to guide the forward and backward movement of the positioning block 5. The two connecting rods 4 are installed above the corresponding clamping pieces 2, which makes installation more convenient.
[0018] In this embodiment, the clamping drive mechanism includes: two drive arms 11, a drive shaft 12, a roller 13, and a swing arm 14. The front ends of the two drive arms 11 are respectively fixed to the rear ends of the two clamping pieces 2. The rear ends of the two drive arms 11 are stacked one on top of the other. A motion curve groove 15 is provided on the rear ends of the two drive arms 11. The lower end of the drive shaft 12 passes through the two motion curve grooves 15. One end of the swing arm 14 is hinged to the base plate 1, and the other end of the swing arm 14 is fixed to the drive shaft 12, so that the drive shaft 12 can swing under the restriction of the swing arm 14. The roller 13 is rotatably mounted on the upper end of the drive shaft 12. The cam on the blow-drying and spinning equipment can drive the drive shaft 12 to swing by rolling on the roller 13. After the drive shaft 12 swings, it can drive the two clamping pieces 2 to clamp or open synchronously by cooperating with the two motion curve grooves 15.
