[0043] See also Figure 1-4 The utility model provides a technical solution: a barrier for a packaging machine that is easy to disassemble and replace, including a barrier plate 1,

[0044] A U-shaped elastic metal cover 2 is sleeved on the upper end of the baffle plate 1. The U-shaped elastic metal cover 2 is a U-shaped cover made of elastic metal material, and the front and rear sides of the lower end thereof can be pulled outwards and deformed;

[0045] A disassembly clamping structure 3 is installed between the inner wall of the U-shaped elastic metal cover 2 and the upper end of the outer wall of the baffle plate 1. The disassembly clamping structure 3 realizes the clamping and disassembly of the U-shaped elastic metal cover 2 and the baffle plate 1 by plugging and pulling up and down. When clamping, the U-shaped elastic metal cover 2 is inserted from the upper end of the baffle plate 1, and when disassembling, the U-shaped elastic metal cover 2 is pulled out from the upper end of the baffle plate 1;

[0046] The clamping and stabilizing structure 5 is assembled between the top surface of the inner cavity of the U-shaped elastic metal cover 2 and the top surface of the baffle plate 1. The position of the U-shaped elastic metal cover 2 and the baffle plate 1 after clamping is limited by the clamping and stabilizing structure 5 to prevent the baffle plate 1 from being horizontally positioned in the U-shaped elastic metal cover 2.

[0047] In some embodiments, in order to realize the clamping and disassembly of the U-shaped elastic metal cover 2 and the baffle plate 1 by plugging and unplugging, the disassembly clamping structure 3 includes:

[0048] Two first triangular clamping blocks 31 are symmetrically distributed in the front and rear directions. The two first triangular clamping blocks 31 are integrally formed at the front and rear sides of the upper edge of the outer wall of the baffle plate 1 respectively;

[0049] The bottom surface of the first triangular block 31 is a plane;

[0050] The second triangular clamping blocks 32 are symmetrically distributed in two at the front and rear sides. The two second triangular clamping blocks 32 are respectively integrally formed at the front and rear sides of the lower edge of the inner wall of the U-shaped elastic metal cover 2;

[0051] The top surface of the second triangular block 32 is a plane;

[0052] The top surface of the second triangular clamping block 32 is clamped on the bottom surface of the first triangular clamping block 31 on the same side.

[0053] When the U-shaped elastic metal cover 2 is sleeved on the upper end of the baffle plate 1 from the upper end, the slope surfaces of the second triangular clamping blocks 32 on both sides of the lower end of the inner wall of the U-shaped elastic metal cover 2 fit with the slope surfaces of the first triangular clamping blocks 31 on the same side of the upper edge of the outer wall of the baffle plate 1, and the second triangular clamping blocks 32 continue to move downward as the U-shaped elastic metal cover 2 moves downward, and the first triangular clamping blocks 31 squeeze the second triangular clamping blocks 32 on the same side to move outward, thereby opening the two sides of the lower end of the U-shaped elastic metal cover 2, so that the two sides of the lower end of the U-shaped elastic metal cover 2 are deformed and the openings are changed After the slope of the second triangular clamping block 32 passes the slope of the first triangular clamping block 31, the two sides of the lower end of the U-shaped elastic metal cover 2 are deformed and reset. Due to the action of gravity, the top surface of the second triangular clamping block 32 is clamped on the bottom surface of the first triangular clamping block 31 on the same side, achieving a clamping and fixing effect. When disassembly is required, the deformation openings on both sides of the lower end of the U-shaped elastic metal cover 2 are pulled larger, so that the second triangular clamping block 32 is staggered with the first triangular clamping block 31 on the same side, and the U-shaped elastic metal cover 2 is pulled out from the upper end of the baffle plate 1.

[0054] In some embodiments, in order to avoid contact wear between the first triangular block 31 and the second triangular block 32, a first rubber layer 33 is adhered and fixed to the bottom surface of the first triangular block 31, and the top surface of the second triangular block 32 abuts against the first rubber layer 33. When the outer grid baffle 1 is impacted by the product, the first rubber layer 33 buffers the contact surface of the first triangular block 31 and the second triangular block 32 to avoid contact wear between the first triangular block 31 and the second triangular block 32.

[0055] In some embodiments, in order to lift up the rectangular plate 53 and clamp it in the rectangular clamping groove 51 through elastic action to prevent the baffle plate from lateral displacement in the U-shaped elastic metal cover, the clamping and stabilizing structure 5 includes:

[0056] A rectangular slot 51 is provided on the top surface of the inner cavity of the U-shaped elastic metal cover 2 along the length direction;

[0057] A rectangular plate 53, which is snap-fitted into the rectangular slot 51;

[0058] The bottom surface of the rectangular plate 53 is evenly fixedly connected with a spring 52 along the length direction. The lower end of the spring 52 is fixedly connected to the upper end of the baffle plate 1. The spring 52 provides elasticity to lift the rectangular plate 53 and clamp it in the rectangular slot 51. At the same time, this elastic action prevents the baffle plate 1 from shaking up and down in the U-shaped elastic metal cover 2, thereby improving the stability of the baffle plate 1 during use.

[0059] In some embodiments, in order to enable the extended baffles 4 on both sides to slide and extend to different lengths, the overall length of the baffle plate 1 and the extended baffle plates 4 on both sides is adjusted to increase the applicable range of the device and be applicable to the feeding shielding of conveyor belts of different widths, a rectangular groove 9 is provided on the bottom surface of the baffle plate 1 along the length direction, and the two ends of the rectangular groove 9 extend to the end surfaces of both sides of the baffle plate 1;

[0060] Both ends of the rectangular groove 9 are slidably assembled with an extended baffle plate 4 in an interference fit manner, and the bottom surface of the extended baffle plate 4 and the bottom surface of the baffle plate 1 are located on the same plane.

[0061] In some embodiments, in order to position and guide the sliding of the extended baffle plate 4 in the rectangular groove 9 and prevent the extended baffle plate 4 from moving up and down in the rectangular groove 9, a sliding groove 11 is opened on the outer wall of the extended baffle plate 4 along the length direction, and a slider 10 is integrally formed on the inner wall of the rectangular groove 9 corresponding to the sliding groove 11, and the slider 10 is slidably assembled in the sliding groove 11.

[0062] In some embodiments, in order to facilitate pulling the lower ends of the front and rear side walls of the U-shaped elastic metal cover 2 by grasping the retaining edge 21, so that the deformation openings on both sides of the lower end of the U-shaped elastic metal cover 2 are enlarged, the lower edges of the front and rear side walls of the U-shaped elastic metal cover 2 are integrally formed with retaining edges 21, and the upper and lower surfaces of the retaining edges 21 are coated with an anti-slip layer.

[0063] In some embodiments, in order to drive the U-shaped elastic metal cover 2 and the baffle plate 1 to be lifted and lowered, a lifting mechanism 6 is detachably fixedly mounted on the middle of the top surface of the U-shaped elastic metal cover 2, and the lifting mechanism 6 includes:

[0064] The cylinder 61 has a connection block 62 detachably fixedly mounted at its lower end by bolts;

[0065] The upper end of the outer wall of the cylinder 61 is detachably fixed with an upper mounting seat 63 by bolts;

[0066] The outer wall of the connecting block 62 is detachably fixed with a lower L-shaped mounting seat 64 by bolts;

[0067] The transverse portion of the lower L-shaped mounting seat 64 is detachably fixedly assembled with the middle portion of the top surface of the U-shaped elastic metal cover 2 by means of bolts.

[0068] In some embodiments, in order to prevent the bolted joints from loosening, spring washers 8 are sleeved on the bolts in the lifting mechanism 6, and the spring washers 8 fit the bottom surfaces of the nuts of the corresponding bolts.

[0069] In some embodiments, in order to improve the stability of the connection between the lower end of the lifting mechanism 6 and the U-shaped elastic metal cover 2, a second rubber layer 7 is glued and fixed to the bottom surface of the lateral part of the lower L-shaped mounting seat 64. When vibration occurs, the second rubber layer 7 is used for buffering, and the second rubber layer 7 is in contact with the middle of the top surface of the U-shaped elastic metal cover 2.

[0070] Working principle:

[0071] A disassembly clamping structure 3 is installed between the inner wall of the U-shaped elastic metal cover 2 and the upper end of the outer wall of the baffle plate 1. The disassembly clamping structure 3 realizes the clamping and disassembly of the U-shaped elastic metal cover 2 and the baffle plate 1 by plugging and pulling up and down. When clamping, the U-shaped elastic metal cover 2 is inserted from the upper end of the baffle plate 1, and when disassembling, the U-shaped elastic metal cover 2 is pulled out from the upper end of the baffle plate 1;

[0072] The positions of the U-shaped elastic metal cover 2 and the baffle plate 1 after being clamped are limited by the clamping stabilizing structure 5 to prevent the baffle plate 1 from being horizontally positioned in the U-shaped elastic metal cover 2, thereby ensuring the stability of the baffle plate 1 in use.
