A high-temperature bottle clamp

Abstract

This utility model discloses a high-temperature bottle clamp, comprising a base, multiple holding units, a cylinder, and a metal piston.

A support arm is provided on one of the first connecting rods. A second connecting rod is provided between the support arm and the piston. Heat-insulating guide sleeves are provided at each rotatable connection position of the first connecting rod and each rotatable connection position of the second connecting rod.

Description

Technical Field

[0001] This utility model belongs to the field of material handling technology, and in particular relates to a high-temperature bottle clamp. Background Technology

[0002] In the automated bottle production process, after a bottle is removed from the mold, it needs to be immediately transferred to the next workstation to ensure the efficiency of the entire automated process. When the bottle is removed from the mold, the heat from the bottle has not completely dissipated, resulting in a relatively high temperature. In some production stages or assembly lines, grippers are often used to transfer bottles. These grippers can precisely control the gripping force and position, preventing bottles from being deformed by squeezing or slipping and breaking during transfer. Compared to traditional manual operations, grippers can operate continuously, achieving a gripping frequency of dozens of times per minute in conjunction with automated production lines. Furthermore, due to the diverse specifications of bottles (such as differences in diameter, height, and material), the grippers can be quickly changed or intelligently adjusted to adapt to different products.

[0003] Chinese patent document CN209507030U discloses a bottle clamping device, including a base, a rotary cylinder, a rotating arm, a rolling bearing, and a gripper device. One end of the rotating arm is connected to the upper part of the base via the rotary cylinder; and a limiting rod is provided on the base. The upper end of the gripper device is connected to the other end of the rotating arm via the rolling bearing. The gripper device includes a gripper arm, a cylinder, a clamping plate, grippers, and a connecting rod. The reciprocating motion of the rotating arm is achieved by the rotary cylinder. This design is simple in structure and easy to control. The limiting device added to the base serves two purposes: first, it provides protection; second, it can be adjusted according to the length of the bottle being manufactured to prevent collisions with the bottle. A new gripper device was designed based on the actual glass bottle production process, which satisfies the gripping requirement while preventing bottle breakage.

[0004] In the aforementioned patented solution, during repeated contact between the gripper and the bottle, the bottle's heat is conducted to the cylinder. Conventional cylinders are often not heat-resistant, and the rubber seals within them deform under heat, leading to seal failure. This seal failure reduces the gripper's movement accuracy, further causing the bottle to slip due to instability or excessive clamping force that damages the bottle. Using a high-temperature resistant cylinder increases the overall cost of the gripper device. Furthermore, due to the diverse bottle specifications (such as diameter, height, and material differences), the grippers also come in various specifications with low reusability, resulting in significant resource waste. Utility Model Content

[0005] To overcome the technical problems in existing technologies where repeated contact between the gripper and the bottle leads to heat transfer from the bottle to the cylinder, affecting the airtightness of the conventional cylinder and further reducing the piston's movement accuracy, potentially causing bottle clamping failure, and using high-temperature resistant cylinders significantly increases costs and has low reusability, this invention aims to provide a high-temperature bottle clamping gripper. This is achieved by incorporating a self-made cylinder with a metal piston, along with a first and second connecting rod with heat-insulating guide sleeves. This extends the distance between the clamping position and the self-made cylinder, increasing the heat conduction distance and providing heat insulation, reducing the impact of the high-temperature bottle on the piston's airtightness, maintaining the piston's movement accuracy, and ensuring bottle clamping precision.

[0006] To achieve the above objectives, this utility model employs the following technical solution: a high-temperature clamping bottle gripper, comprising a base, multiple gripping units evenly distributed circumferentially in front of the base, a cylinder disposed behind the base, and a metal piston slidably connected within the cylinder; each gripping unit comprises two parallel first connecting rods, one end of which is rotatably connected to the base, and gripping fingers rotatably connected to the other ends of the two first connecting rods; wherein, a support arm is provided on one of the first connecting rods; a second connecting rod is provided between the support arm and the piston, with both ends of the second connecting rod rotatably connected to the support arm and the piston, respectively; each rotatable connection position of the first connecting rod and each rotatable connection position of the second connecting rod are respectively provided with heat-insulating guide sleeves.

[0007] The guide sleeve can be made of engineering plastics (PEEK, PI) and ceramics (ZrO2, Si3N4) with excellent heat insulation and lubrication capabilities, which reduces the heat transfer from the clamp to the cylinder; at the same time, the cylinder and the piston are both made of metal, which greatly improves the high temperature resistance and reduces the manufacturing cost.

[0008] Furthermore, it includes a sealing plate disposed at the end of the cylinder away from the base, an air pipe disposed between the sealing plate and the base, and a docking plate disposed at the end of the sealing plate away from the cylinder; the two communication positions of the air pipe and the cylinder are respectively located on both sides of the piston.

[0009] Specifically, the end of the sealing plate away from the cylinder is provided with a second connecting hole that communicates with the air pipe; the docking plate is provided with a first air pipe connection hole that communicates with the second connecting hole.

[0010] Optionally, the end of the first tracheal inlet is located on the side of the docking plate.

[0011] Optionally, the end of the first tracheal inlet is located at the middle of the end of the docking plate away from the sealing plate.

[0012] Specifically, the end of the sealing plate away from the cylinder is provided with a through hole; the through hole is directly opposite to and connected to the cylinder; the through plate is provided with a fourth air pipe connection hole that is connected to the through hole.

[0013] Optionally, the end of the fourth air pipe connection hole is located on the side of the docking plate.

[0014] Optionally, the end of the fourth air pipe connection hole is located at the middle of the end of the docking plate away from the sealing plate.

[0015] Optionally, the side wall of the sealing plate is provided with a third air pipe connection hole that communicates with the cylinder.

[0016] Furthermore, a clamping block is detachably connected to the clamping finger; a piston rod is provided on the piston and is slidably and sealingly connected to the base; a linkage disc is provided on the piston rod; and multiple drive arms are provided on the outer periphery of the linkage disc, each of which is rotatably connected to the corresponding second connecting rod.

[0017] Furthermore, the end of the docking plate away from the sealing plate is provided with a plurality of locking posts evenly distributed along the circumferential direction; the end of the locking post is provided with a conical head; and the outer periphery of the locking post is provided with an inner concave ring.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. This utility model uses a self-made cylinder with a metal piston, which improves heat resistance, is cheaper to manufacture, and has a longer service life.

[0020] 2. This utility model also includes a first connecting rod and a second connecting rod with a heat-insulating guide sleeve, which extends the heat transfer distance between the bottle clamping end and the cylinder. At the same time, the heat-insulating guide sleeve also reduces the efficiency of heat transfer, further reducing the impact of high temperature on the airtightness and motion accuracy of the cylinder, and ensuring the success rate of bottle clamping.

[0021] 3. This utility model is easy to replace, lightweight, and can reduce the load; the grippers can be quickly replaced and are compatible with a variety of products; it has multiple types of gas pipe interfaces and has a wide range of applications. Attached Figure Description
