[0023] The present utility model will now be described in further detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only showing the basic structure of the present utility model in a schematic manner. Therefore, they only show the components related to the present utility model. Directions and references (such as up, down, left, right, etc.) can only be used to assist in the description of the features in the drawings. Therefore, the following specific embodiments are not adopted in a restrictive sense, and the scope of the claimed subject matter is only defined by the appended claims and their equivalent forms.

[0024] As Figure 1 shown, a pneumatic chuck with a double clamping roller and double adjustment structure includes a chuck seat 1 and a plurality of clamping components 2 arranged circumferentially along the chuck seat 1. Each clamping component 2 includes two clamping rollers 201 arranged vertically, a cylinder 202 connected to one of the clamping rollers 201 and used to drive it to clamp or release the material, a manual push-pull rod 203 connected to the other clamping roller 201 and used to drive it to clamp or release the material, and a synchronous beam 204 connected between the two clamping rollers 201 to make the two clamping rollers 201 move synchronously.

[0025] During normal operation, the cylinder 202 is started, and the cylinders 202 in each clamping component 2 drive the corresponding clamping rollers 201 to move. At the same time, the clamping roller 201 drives the other clamping roller 201 in the same clamping component 2 to move synchronously through the synchronous beam 204, forming a synchronous movement of the double clamping rollers 201 to clamp the material. When one of the cylinders 202 fails and cannot clamp or release the material, the manual push-pull rod 203 in the clamping component 2 where the cylinder 202 is located can drive the corresponding clamping roller 201 to move. At the same time, the clamping roller 201 drives the other clamping roller 201 (the clamping roller 201 corresponding to the faulty cylinder 202) to move synchronously through the synchronous beam 204. The start-up chuck adds a manual function on the basis of pneumatic to cope with sudden failures, improving the practicability of the pneumatic chuck.

[0026] In some examples, there are four clamping components 2, including two horizontally arranged clamping components 2 arranged oppositely and two vertically arranged clamping components 2 arranged oppositely, which clamp the material horizontally and vertically.

[0027] In some examples, as Figures 2 - 4 shown, among the two manual push-pull rods 203 in the horizontal clamping component 2 and the vertical clamping component 2, one manual push-pull rod 203 is used to push the corresponding clamping roller 201 to clamp the material, which is the push rod 2031, and the other manual push-pull rod 203 is used to pull the corresponding clamping roller 201 to release the material, which is the pull rod 2032.

[0028] In some examples, an installation portion 2021 is formed by extending the cylinder block of the cylinder 202 towards the direction of the manual push-pull rod 203. The push rod 2031 is threadedly connected to the corresponding installation portion 2021, and the head of the push rod 2031 faces the roller seat 205 for installing the pinch roller 201. By rotating the push rod 2031, the push rod 2031 can move towards or away from the pinch roller 201. When the cylinder 202 corresponding to the push rod 2031 fails and the pinch roller 201 cannot clamp the material, rotate the push rod 2031 to make it move towards the pinch roller 201. When it abuts against the roller seat 205, continue to rotate the push rod 2031, and the push rod 2031 can push the roller seat 205 and the pinch roller 201 thereon to clamp the material.

[0029] In some examples, a through hole 2022 for the pull rod 2032 to pass through is formed in the installation portion 2021. The cross-sectional area of the through hole 2022 is larger than that of the pull rod 2032, and the pull rod 2032 is slidably connected to the through hole 2022. The pull rod 2032 passes through the through hole 2022 and is fixedly connected to the corresponding roller seat 205. When the cylinder 202 corresponding to the pull rod 2032 fails and the pinch roller 201 cannot release the material, pull the pull rod 2032 in the direction away from the pinch roller 201, and the pull rod 2032 drives the pinch roller 201 to release the material.

[0030] In some examples, the pull rod 2032 is threadedly connected to the roller seat 205, and the roller seat 205 is provided with an abutting bolt for abutting against the pull rod 2032. The roller seat 205 is provided with a connection hole connected to the pull rod 2032 and an abutting hole 2051 for the abutting bolt to be screwed into. The connection hole communicates with the abutting hole 2051. The abutting bolt is screwed into the abutting hole 2051 to abut against the pull rod 2032, which can improve the connection strength between the pull rod 2032 and the roller seat 205.

[0031] In some examples, the synchronous beam 204 includes a beam body 2041 and two connecting arms 2042 fixed at both ends of the beam body 2041. The ends of the two connecting arms 2042 away from the beam body 2041 are respectively fixedly connected to the two roller seats 205. The synchronous beam 204 has a "U" - shaped structure, which can drive the two pinch rollers 201 to move synchronously.

[0032] In some examples, there are two synchronous beams 204 in each clamping assembly 2. The two synchronous beams 204 are symmetrically arranged and distributed on both sides of the cylinder 202, so as to avoid the skew of the pinch roller 201 during the movement process and improve the clamping accuracy of the pinch roller 201.

[0033] In some examples, the manual push - pull rod 203 is a screw rod, and a nut 2033 is provided at one end of the screw rod away from the pinch roller 201. The nut 2033 can be used as an operating part, thus facilitating the rotation or pulling of the screw rod.

[0034] Working principle:

[0035] During normal operation, the starting cylinder 202 is activated, and the cylinders 202 in each clamping assembly 2 drive the corresponding pinch rollers 201 to move. At the same time, the pinch roller 201 drives another pinch roller 201 in the same clamping assembly 2 to move synchronously through the synchronous beam 204, forming the synchronous movement of the double pinch rollers 201 to clamp or release the material.

[0036] When the cylinder 202 corresponding to the push rod 2031 fails and the pinch roller 201 cannot clamp the material, rotate the push rod 2031 to move it in the direction close to the pinch roller 201. When it abuts against the roller seat 205, continue to rotate the push rod 2031. The push rod 2031 can push the roller seat 205 and the pinch roller 201 thereon to move towards the material. At the same time, the pinch roller 201 drives another pinch roller 201 (the pinch roller 201 corresponding to the faulty cylinder 202) to move synchronously through the synchronous beam 204 to clamp the material.

[0037] When the cylinder 202 corresponding to the pull rod 2032 fails and the pinch roller 201 cannot release the material, pull the pull rod 2032 in the direction away from the material. The pull rod 2032 moves, and at the same time, the pinch roller 201 drives another pinch roller 201 (the pinch roller 201 corresponding to the faulty cylinder 202) to move synchronously through the synchronous beam 204 to release the material.
