Description

Technical Field

[0001] This utility model relates to the field of bottle capping technology, specifically a pneumatic capping gripper mechanism. Background Technology

[0002] A pneumatic capping machine is a device that uses compressed air as a power source and is mainly used to securely fix bottle caps to bottles or containers.

[0003] Currently, most existing pneumatic capping machines have grippers of fixed size or that can only be adjusted within a limited range. When dealing with bottle caps of various sizes, the grippers need to be changed frequently, which not only increases the complexity of operation but also consumes a lot of time and labor costs. Moreover, frequent gripper changes may also lead to accelerated wear and tear on the equipment and reduce its service life. In view of this, we propose a pneumatic capping gripper mechanism. Utility Model Content

[0004] The main objective of this invention is to provide a pneumatic capping gripper mechanism that can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a pneumatic capping gripper mechanism, comprising a mounting flange shaft, a sleeve fixedly connected to the lower end of the mounting flange shaft, a mounting shaft fixedly connected to the lower end of the sleeve, a cylindrical body located below the mounting shaft, and a gripper mechanism mounted on the mounting shaft. The gripper mechanism includes:

[0006] A connecting arm is hinged to a mounting shaft, and a rod is fixedly connected to the connecting arm. The rod has a sliding groove.

[0007] A sliding rod, which passes through the rod body and is slidably connected to the rod body, and the upper end of the sliding rod is penetrated by a fixing bolt and threadedly connected to the fixing bolt;

[0008] The base has a sliding groove on its side wall. The base is hinged to the bottom end of the sliding rod. A locking block and a limiting block are slidably connected to the inner wall of the base. A sliding rod is fixedly connected to the side wall of the limiting block. The sliding rod is slidably connected to the sliding groove.

[0009] The pressing block has a T-shaped rod fixedly connected to its outer wall. The T-shaped rod is slidably connected to the base. The T-shaped rod has a limit groove. The end of the pressing block is provided with polyurethane for cushioning.

[0010] Preferably, a sliding plate is fixedly connected to the end of the sliding rod, and the sliding plate has a slot.

[0011] Preferably, a limiting rod is hinged to the outer wall of the base, and the upper end of the limiting rod is connected to the outer wall of the base by a spring.

[0012] Preferably, the sleeve has a cavity, an openable air inlet, and a closed air inlet. A piston shaft is slidably connected to the inner wall of the cavity. The openable air inlet is composed of multiple holes and is sealed by a plug during use, allowing gas to directly reach the cavity below the piston shaft.

[0013] Preferably, a sealing ring is fixedly connected to the outer wall of the piston shaft, and multiple sets of the sealing ring are provided.

[0014] Preferably, a hinge rod is hinged to the lower end of the piston shaft, and the end of the hinge rod away from the piston shaft is hinged to the end of the connecting arm.

[0015] This utility model provides a pneumatic cap-screwing gripper mechanism. It has the following advantages:

[0016] (1) When it is necessary to twist bottle caps of different sizes, the pneumatic cap screwing claw mechanism only needs to pull the pressing block to slide on the base. After adjusting to the corresponding position, the locking block will spring into the limiting groove under the action of the spring force. Finally, the limiting block limits the locking block, thereby fixing the pressing block. This design allows the claw to flexibly adapt to bottle caps of different sizes, greatly improving the applicability of the claw and reducing the cost for enterprises to equip multiple claws due to the variety of bottle cap sizes.

[0017] (2) When the pneumatic capping gripper mechanism needs to operate bottles of different heights, it is only necessary to loosen the fixing bolt first, pull the slide bar to the appropriate position, and finally tighten the fixing bolt to complete the height adjustment of the pressing block. This design enables the gripper to adapt to bottles of different heights, further improving the applicability and versatility of the entire gripper, reducing the replacement cost of the equipment and the complexity of operation, and improving production efficiency.

[0027] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 This utility model proposes a pneumatic capping gripper mechanism, including a mounting flange shaft 1, a sleeve 2 fixedly connected to the lower end of the mounting flange shaft 1, the sleeve 2 having a cavity 20, an opening / closing air inlet 21 and a closing air inlet 22, a piston shaft 23 slidably connected to the inner wall of the cavity 20, a sealing ring 24 fixedly connected to the outer wall of the piston shaft 23, multiple sets of sealing rings 24, a hinge rod 25 hinged to the lower end of the piston shaft 23, the end of the hinge rod 25 away from the piston shaft 23 being hinged to the end of the connecting arm 51, a mounting shaft 3 fixedly connected to the lower end of the sleeve 2, a cylinder 4 provided below the mounting shaft 3, and a gripper mechanism provided on the mounting shaft 3.

[0030] In an embodiment of this utility model, in order to improve the applicability of the gripper, the gripper mechanism specifically includes a connecting arm 51, which is hinged to the mounting shaft 3. A rod 52 is fixedly connected to the connecting arm 51. The rod 52 has a sliding groove 521. A sliding rod 53 passes through the rod 52 and is slidably connected to the rod 52. The upper end of the sliding rod 53 is passed through by a fixing bolt 531 and is threadedly connected to the fixing bolt 531. A sliding groove 540 is provided on the side wall of the base 54. The base 54 is hinged to the bottom end of the sliding rod 53. A locking block 544 and a limiting block 545 are slidably connected to the inner wall of the base 54. A sliding rod 546 is fixedly connected to the side wall of the limiting block 545. The sliding rod 546 is slidably connected to the sliding groove 540. A T-shaped rod 551 is fixedly connected to the outer wall of the pressing block 55. The T-shaped rod 551 is slidably connected to the base 54. A limiting groove 552 is provided on the T-shaped rod 551.

[0031] Furthermore, a sliding plate 541 is fixedly connected to the end of the sliding rod 546. The sliding plate 541 has a slot 542. A limit rod 543 is hinged to the outer wall of the base 54. The upper end of the limit rod 543 is connected to the outer wall of the base 54 through a spring.

[0032] In this invention, during use, the bottle body is first fixed directly below the gripper, and then the bottle cap is placed at the bottle opening. It should be noted that the cylinder 4 is elastically connected to the mounting shaft 3 via a spring, allowing it to move up and down to stabilize the bottle cap. Compressed air is then supplied to the cavity 20 through the closed air inlet 22, causing the piston shaft 23 to move downwards and upwards. The piston shaft 23 drives the hinge rod 25, causing the pressing block 55 to press against the outer wall of the bottle cap. Subsequently, by driving the rotation, the mounting flange shaft 1 rotates the entire gripper, thus completing the cap tightening operation. When it is necessary to tighten bottle caps of different sizes, such as... Figure 4 and Figure 5As shown, simply pull the sliding plate 541. The sliding rod 546, fixedly connected to the sliding plate 541, causes the limiting block 545 to slide, thereby releasing the limiting position of the locking block 544. When the sliding plate 541 slides a certain distance, it presses against the limiting rod 543, causing it to rotate. When the end of the limiting rod 543 coincides with the slot 542, it resets under the spring force, thus limiting the sliding plate 541 and the limiting block 545. When the limiting position of the locking block 544 is released, simply pull the pressing block 55, causing it to slide on the base 54. During the sliding process of the pressing block 55... The limiting groove 552 will squeeze the locking block 544, so that the locking block 544 is fully inserted into the base 54. When the pressing block 55 is adjusted to the corresponding position, the locking block 544 will spring back into the limiting groove 552 under the elastic force of the spring. Then, press the limiting rod 543 to release the limiting of the sliding plate 541. At this time, the limiting block 545 will limit the locking block 544 again under the elastic force of the spring, thereby fixing the pressing block 55. When it is necessary to operate bottles of different heights, simply loosen the fixing bolt 531 first, then pull the sliding rod 53 to the appropriate position, and finally tighten the fixing bolt 531 to complete the adjustment of the pressing block 55, thereby improving the applicability of the entire gripper.

[0033] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
