Description

Technical Field

[0001] This utility model belongs to the technical field of bottle rubber ring loading and unloading machines, and specifically relates to a variable diameter bottle rubber ring loading and unloading machine clamp. Background Technology

[0002] The bottle sealing ring loading and unloading machine is a device specifically designed for the automated loading and unloading of sealing rings on various bottles. It achieves efficient and precise installation and removal of sealing rings through a mechanical structure. The core of the equipment consists of a fixed support, clamping fixtures, and a transmission system. During operation, the bottle is first securely fixed, and then the clamping components are driven by a motor to slide along the bottle, using squeezing or resistance force to load or unload the sealing ring. It is highly versatile, adaptable to bottles of different diameters and heights by adjusting the clamping parameters. Operation is simple and safe, avoiding the problems of sealing ring damage and installation errors associated with manual loading and unloading, significantly improving work efficiency and reducing labor costs. It is widely used in industries requiring bottle sealing, such as chemical, food, and medical industries.

[0003] Announcement No. "CN218927632U" describes a variable-diameter cylinder rubber ring loading and unloading machine clamp, comprising a main body consisting of two parallel fixed discs connected together by multiple evenly distributed fixed shafts. Multiple clamping arms are installed between the two fixed discs, rotatably connected to the fixed discs via rotating shafts. These arms can simultaneously rotate inwards to open or retract under the action of a synchronous mechanism, and can be fixed by a locking mechanism. This variable-diameter cylinder rubber ring loading and unloading machine clamp allows multiple clamping arms to open and close synchronously, adjusting the inner diameter. It can accommodate cylinders of various diameters, eliminating the need to change different clamps, making the work more convenient, faster, and significantly improving efficiency.

[0004] While the aforementioned utility model can adapt to various types of steel cylinders with different diameters, eliminating the need to change different clamps and making the work more convenient, faster, and more efficient, it cannot form a coordinated clamping structure by assembling multiple sets of clamps. Relying solely on single or fixed combinations of clamp units makes it difficult to provide balanced clamping force according to the bottle specifications. Uneven force can easily cause the bottle to shake or tilt. On the other hand, the inability to adjust the spacing makes the clamps unsuitable for bottles with different diameters and heights. When dealing with bottles with significant size differences, either the spacing is too wide, leading to loose clamping, or the spacing is too narrow, resulting in excessive compression. Both situations can cause unstable bottle clamping, leading to misalignment of the rubber ring during installation and removal, damage to the rubber ring, or even bottle slippage, which are safety and quality issues that seriously restrict the practicality and production stability of the equipment. Utility Model Content

[0005] In response to the problems mentioned in the background art, the purpose of this utility model is to provide a variable diameter bottle rubber ring loading and unloading machine clamp to solve the problems that cannot be formed by assembling multiple sets of clamps to form a collaborative clamping structure, and that it is difficult to provide a balanced clamping force according to the bottle specifications by relying on only a single or fixed combination of clamp units. The bottle is prone to shaking and tilting due to uneven force. On the other hand, the inability to adjust the spacing makes the clamp unable to adapt to bottles of different diameters and heights.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A variable-diameter bottle ring loading and unloading machine clamp includes columns, a top plate fixedly connected to the top of the columns, a cylinder fixedly connected to the top of the top plate, a limit component fixedly connected to the telescopic end of the cylinder, a first clamping seat fixedly connected between the columns, a second clamping seat movably connected to the bottom of the first clamping seat, clamping components installed on both sides of the first and second clamping seats, arc-shaped clamping blocks installed inside the first and second clamping seats, and assembly components symmetrically installed on both sides of the first and second clamping seats. A limit post and a limit tube are movably connected between the first and second clamping seats, and the limit post and the limit tube are slidably connected.

[0008] The assembly includes a cavity, a return spring, a movable plate, a connecting post, a handle, and a fixing block. The first and second clamping seats are symmetrically embedded with fixing seats on both sides. Each fixing seat has a cavity inside. A return spring is fixedly connected to one side of the cavity, and a movable plate is fixedly connected to the other end of the return spring. The movable plate is slidably connected to the cavity. A connecting post is fixedly connected to one side of the movable plate, and a handle is fixedly connected to the other end of the connecting post extending outwards from the fixing seat. A fixing block is fixedly connected to the other side of the movable plate. A mounting plate is fixedly connected to one end of both the limiting post and the limiting tube. An assembly block is fixedly connected to one side. Assembly slots are symmetrically opened at the bottom of the first clamping seat and the top of the second clamping seat. The assembly block and the assembly slot are plugged in. A fixing slot is opened on one side of the assembly block. The fixing block and the fixing slot are plugged in, which can form a cooperative clamping structure. The multi-point balanced force is used to enhance the stable fixation of the bottle and avoid the shaking or tilting problem when clamped by a single clamp. Moreover, it can flexibly adapt to bottle specifications of different diameters and heights. By precisely adjusting the spacing, it ensures that the clamp and the bottle fit tightly, which not only prevents the clamping from loosening due to excessive spacing, but also avoids excessive squeezing due to excessive spacing.

[0009] As a preferred technical solution, the clamping assembly includes a fixed post, a threaded hole, a threaded rod, and a knob. Fixed posts are embedded and fixedly connected to both sides of the first and second clamping seats. One end of each fixed post has a threaded hole, inside which a threaded rod is threadedly connected. A knob is fixedly connected to one end of the threaded rod, and the other end extends into the first and second clamping seats and rotatably connects to the arc-shaped clamping block. This significantly improves the versatility and applicability of the equipment, eliminating the need for separate special clamps for bottles of different diameters, reducing equipment procurement and replacement costs. It is particularly suitable for multi-category, small-batch production scenarios. Furthermore, it ensures the stability of bottles of different diameters during the installation and removal of rubber rings. Adaptive clamping prevents bottle shaking, tilting, or slippage, ensuring precise alignment during rubber ring installation and removal, and reducing quality problems such as rubber ring damage and installation misalignment caused by unstable clamping.

[0010] As a preferred technical solution, the clamping end of the arc-shaped clamping block is glued with an anti-slip pad. The surface of the anti-slip pad is provided with anti-slip protrusions. The anti-slip pad is made of soft rubber, which has good elasticity and flexibility. It can fit tightly against the surface of bottles of different diameters when clamping. It fills the gaps in the contact surface through slight deformation, enhances the clamping seal and stability, and avoids scratches, indentations and other damage to the bottle surface caused by hard clamping, thus protecting the bottle's appearance.

[0011] In summary, the present invention has the following main advantages:

[0012] First, in this utility model, pulling the handle causes the connecting column to move the moving plate and the fixed block. The moving plate presses against the return spring, which compresses the return spring. The fixed block retracts into the cavity. Then, the limiting column and the limiting tube are combined with the bottom of the first clamping seat, so that the assembly block is inserted into the assembly groove. Releasing the handle resets the return spring, and the moving plate rebounds, causing the fixed block to pop out. The fixed block is then inserted into the fixed groove. Similarly, the second clamping seat is installed to form a collaborative clamping structure. By applying force evenly at multiple points, the stability of the bottle is enhanced, avoiding the shaking or tilting problem when clamped by a single clamp. Moreover, it can flexibly adapt to bottle specifications of different diameters and heights. By precisely adjusting the spacing, the clamp and the bottle are ensured to fit tightly, preventing both loosening due to excessive spacing and excessive squeezing due to excessive spacing.

[0013] Secondly, in this utility model, the bottle is placed between the first clamping seat and the second clamping seat. Rotating the knob controls the threaded rod to rotate. The threaded rod engages with the threaded hole on the fixed post, thereby controlling the threaded rod to drive the arc-shaped clamping block forward. The anti-slip pad at the clamping end of the arc-shaped clamping block fits against the bottle, thus clamping and fixing the bottle. This significantly improves the versatility and applicability of the equipment, eliminating the need for separate special clamps for bottles of different diameters, reducing equipment procurement and replacement costs. It is particularly suitable for multi-category, small-batch production scenarios. Furthermore, it ensures the stability of bottles of different diameters during the installation and removal of the rubber ring. Adaptive clamping prevents the bottle from shaking, tilting, or slipping, ensuring precise alignment during rubber ring installation and removal, and reducing quality problems such as rubber ring damage and installation misalignment caused by unstable clamping.

[0021] Assembled component 13 includes a cavity 131, a return spring 132, a movable plate 133, a connecting post 134, a handle 135, and a fixing block 136. Fixing seats 12 are symmetrically embedded and fixedly connected to both sides of the first clamping seat 5 and the second clamping seat 6. A cavity 131 is formed inside the fixing seat 12. A return spring 132 is fixedly connected to one side of the cavity 131, and a movable plate 133 is fixedly connected to the other end of the return spring 132. The movable plate 133 is slidably connected to the cavity 131. A connecting post 134 is fixedly connected to one side of the movable plate 133, and a handle 135 is fixedly connected to the other end of the connecting post 134 extending outward from the outside of the fixing seat 12. A fixing block 136 is fixedly connected to the other side of the movable plate 133. A mounting plate 7 is fixedly connected to one end of both the limiting post 8 and the limiting tube 9. A mounting plate 7 is fixedly connected to one side of the mounting plate 7. The assembly block 10 is fixedly connected. The bottom of the first clamping seat 5 and the top of the second clamping seat 6 are symmetrically provided with assembly grooves 11. The assembly block 10 is inserted into the assembly groove 11. A fixing groove 14 is provided on one side of the assembly block 10. The fixing block 136 is inserted into the fixing groove 14. Pulling the handle 135 causes the connecting column 134 to move the moving plate 133 and the fixing block 136. The moving plate 133 presses against the return spring 132, and the return spring 132 is compressed. The fixing block 136 retracts into the cavity 131. Then, the limiting column 8 together with the limiting tube 9 is merged with the bottom of the first clamping seat 5, so that the assembly block 10 is inserted into the assembly groove 11. Releasing the handle 135 resets the return spring 132. The moving plate 133 rebounds and causes the fixing block 136 to pop out. The fixing block 136 is inserted into the fixing groove 14.

[0022] refer to Figure 2The clamping assembly 15 includes a fixed post 151, a threaded hole 152, a threaded rod 153, and a knob 154. The fixed post 151 is embedded and fixedly connected to both sides of the first clamping seat 5 and the second clamping seat 6. One end of the fixed post 151 has a threaded hole 152, and the threaded rod 153 is threadedly connected inside the threaded hole 152. One end of the threaded rod 153 is fixedly connected to the knob 154, and the other end of the threaded rod 153 extends into the first clamping seat 5 and the second clamping seat 6 respectively and is rotatably connected to the arc-shaped clamping block 16. When the bottle is placed between the first clamping seat 5 and the second clamping seat 6, the knob 154 is turned to control the threaded rod 153 to rotate. The threaded rod 153 and the threaded hole 152 on the fixed post 151 are threadedly driven, thereby controlling the threaded rod 153 to drive the arc-shaped clamping block 16 forward. The anti-slip pad 17 at the clamping end of the arc-shaped clamping block 16 is in contact with the bottle, thereby clamping and fixing the bottle.

[0023] refer to Figure 2 The curved clamping block 16 has an anti-slip pad 17 glued to its clamping end. The surface of the anti-slip pad 17 has anti-slip protrusions. The anti-slip pad 17 is made of soft rubber. The anti-slip pad 17 has good elasticity and flexibility, and can fit tightly with the surface of bottles of different diameters when clamping. It fills the gaps in the contact surface through slight deformation, enhances the clamping seal and stability, and avoids scratches, indentations and other damage to the bottle surface caused by hard clamping, thus protecting the bottle's appearance.

[0024] Operating principle and advantages: First, pull the handle 135 to move the connecting post 134, which in turn moves the moving plate 133 and the fixing block 136. The moving plate 133 presses against the return spring 132, which compresses the return spring 132, causing the fixing block 136 to retract into the cavity 131. Then, the limiting post 8, together with the limiting tube 9, is joined to the bottom of the first clamping seat 5, allowing the assembly block 10 to be inserted into the assembly groove 11. Release the handle 135, and the return spring 132 returns to its original position. The moving plate 133 then springs back, causing the fixing block 136 to pop out. The fixing block 136 is inserted into the fixing groove 14, and then the second clamping seat 6 is installed in the same way. The bottle is placed between the first clamping seat 5 and the second clamping seat 6. The knob 154 is turned to control the threaded rod 153 to rotate. The threaded rod 153 and the threaded hole 152 on the fixing post 151 are threaded to drive the threaded rod 153 to drive the arc-shaped clamping block 16 forward. The anti-slip pad 17 at the clamping end of the arc-shaped clamping block 16 is in contact with the bottle, so that the arc-shaped clamping block 16 clamps and fixes the bottle.

[0025] This utility model can form a collaborative clamping structure, which uses multi-point balanced force to enhance the stability and fixation of the bottle, avoiding the shaking or tilting problem when clamped by a single clamp. Moreover, it can flexibly adapt to bottle specifications of different diameters and heights. By precisely adjusting the spacing, it ensures that the clamp and the bottle fit tightly, preventing the clamping from loosening due to excessive spacing and avoiding excessive squeezing due to excessive spacing.
