Description

Technical Field

[0001] The utility model relates to the technical field of high-speed feeders, in particular to a pneumatically adjusted clamp. Background Art

[0002] A feeder is a machine that uses the force of the machine's movement to apply force to the material and transport the material. The feeder is an indispensable equipment in light industry and heavy industry, and the clamp is an indispensable part of the feeder.

[0003] According to the existing Chinese utility model patent with announcement number CN220222624U, an adjustable mobile clamp for a feeder is recorded. This structure realizes the lateral movement of the mobile clamp by installing a lateral movement mechanism, which is convenient for adjusting the position of the mobile clamp according to the size of the conveyed material, and is convenient for conveying materials of different sizes. By rotating the adjusting screw (clamping piece), the height from the bottom of the adjusting screw (clamping piece) to the top of the conveyed material is changed, which is convenient for conveying materials of different thicknesses, thereby improving the practicality of the equipment.

[0004] The adjusting screw is rotated to change the height from the bottom of the adjusting screw to the top of the conveyed material, which is convenient for conveying materials of different thicknesses. It is suitable for the situation where the feeder conveys a single material belt. When the clamp conveys multiple material belts, the above structure needs to rotate and adjust each material belt in turn, and the adjustment efficiency is slow. At the same time, when adding a new material belt, it is necessary to loosen the adjusting screw, put in the new material belt, and then repeat the rotation to adjust the thickness of the clamped material. The material changing and debugging process is relatively cumbersome. Therefore, in view of these current situations, it is urgent to develop a pneumatically adjusted clamp to meet the needs of actual use. Utility Model Content

[0020] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0021] See also Figure 1-3 , a pneumatically adjusted clamp is specifically implemented, comprising a crossbeam 1 and a plurality of clamping members 2, the plurality of clamping members 2 are arranged in a vertical linear array structure in the middle of the crossbeam 1, a pressing member that can move up and down is arranged inside the clamping member 2, and the pressing member that can move up and down is used to adjust the thickness of the material clamped by the clamp, the clamping member 2 is composed of a cylinder body 21 with a movable inner cavity 23 inside, the pressing member is a cylinder shaft 22 arranged inside the clamping member 2, the cylinder shaft 22 is arranged inside the movable inner cavity 23 so as to move up and down, and the bottom end of the cylinder shaft 22 extends to the bottom of the cylinder body 21, a ring sealing groove 223 is arranged in the middle of the cylinder shaft 22, and a sealing rubber ring is arranged inside the ring sealing groove 223;

[0022] A reset member 24 is also provided inside the cylinder body 21, and the cylinder shaft 22 is reset upward by the reset member 24. An air inlet interface 25 is provided on one side of the cylinder body 21. The air inlet interface 25 is in a conducting structure with the moving inner cavity 23, and the air inlet interface is used to connect with an external air inlet pipe.

[0023] Specifically, Figure 2 and 3 As shown, the air inlet interface 25 is arranged at the top of the movable inner cavity 23, and when the cylinder shaft 22 moves upward to the top of the movable inner cavity 23 through the reset member 24, the sealing rubber ring and the air inlet interface 25 are located at the same height, and the reset member 24 is composed of a spring, and the spring is sleeved on the middle part of the cylinder shaft 22, one end of the spring abuts against the bottom end surface of the ring sealing groove 223, and one end of the spring abuts against the bottom end surface of the movable inner cavity 23.

[0024] When the air inlet interface 25 intakes air into the movable inner cavity 23 in the cylinder body 21, the gas can be located at the top of the movable inner cavity 23 to push the sealing rubber ring, so that the cylinder shaft 22 moves toward one end of the reset member 24 and squeezes the reset member 24. When the clamping part 221 of the cylinder shaft 22 contacts and clamps the material belt, the air pressure in the movable inner cavity 23 is maintained through the air inlet interface 25, so that the clamping part 221 of the cylinder shaft 22 is maintained at an appropriate height, thereby completing the thickness adjustment of the clamp material belt.

[0025] The clamping member 2 is composed of a cylinder body 21 with a movable inner cavity 23 inside, and the pressure member is a cylinder shaft 22 arranged inside the clamping member 2. When the clamping thickness of the clamp needs to be adjusted, air is introduced through the movable inner cavity 23 in the cylinder body 21 to push the cylinder shaft 22 downward to clamp the material belt. The height of the cylinder shaft 22 can be quickly adjusted without manual rotation adjustment one by one. The efficiency of the height adjustment of the cylinder shaft 22 is improved by the principle of pneumatic lifting.

[0026] In a further embodiment, Figure 1 and Figure 3 The top of the cylinder shaft 22 extends upward to the top of the cylinder body 21, and the top of the cylinder body 21 is provided with a limiter 3, which is connected to the top of the cylinder shaft 22. The top of the cylinder shaft 22 is a threaded portion 222, and the limiter 3 is composed of a limit nut. After the cylinder shaft 22 moves downward by air pressure, the limit nut is threadedly connected to the threaded portion 222, and the cylinder shaft 22 forms a downward limit structure with the cylinder body 21 through the limit nut.

[0027] When the feeder is replenished with a new material belt, the gas in the mobile inner cavity 23 can be quickly leaked through the cylinder body 21, and the reset member 24 composed of a spring provides an upward elastic reset force to the cylinder shaft 22. The cylinder shaft 22 is located inside the mobile inner cavity 23 and rises rapidly, providing space for replacement when the user replaces or replenishes a new material belt. After the replacement is completed, air is supplied to the mobile inner cavity 23 in the cylinder body 21 through the air inlet interface 25, so that the cylinder shaft 22 moves toward one end of the reset member 24. At the same time, the limit member 3 maintains the same limit height as the previous material belt, and forms a downward limit structure with the limit nut and the cylinder body 21. When replenishing a new material belt, there is no need to adjust the descending height of the cylinder shaft 22, which plays a role in quickly resetting the original clamping height.
