[0002] Loom, also known as spinning machine, weaving machine, cotton spinning machine, etc., early looms were all human-driven looms. Shuttleless loom technology has been studied since the 19th century and has been gradually introduced to the international market since the 1950s. Since the 1970s, many new shuttleless looms have been put on the market. Shuttleless looms have achieved remarkable results in improving fabrics and improving the efficiency of looms. They have been widely used in countries around the world and have accelerated the process of weaving equipment transformation. The share of shuttleless looms in many developed countries has reached about 80%, and there has been a general trend of replacing shuttle looms with shuttleless looms.

[0032] By setting up the clamping mechanism 2, the sacks can be limited during weaving to prevent the sacks from shifting, which would cause the position of the sacks to change, making it impossible to weave the sacks normally, or causing the weaving to fail, resulting in waste of materials. By setting up the transport mechanism 3, the sacks can be automatically discharged after weaving, saving the operator the step of taking out the sacks by themselves, reducing a certain amount of labor costs, and also avoiding the problem that the splint may clamp the operator's hands.

[0033] Example 2

[0034] In one embodiment, limit rods 209 are fixedly installed on all four sides of the top of the workbench 1, and the surfaces of the four limit rods 209 are slidably connected to the inner surfaces of the upper clamping plate 208 and the lower clamping plate 205. Sliding rods 210 are fixedly installed on the front and rear sides of the top of the L-shaped plate 7. The outer surfaces of the two sliding rods 210 are slidably connected to the inner surfaces of the second tooth plate 206 and the first tooth plate 203. The fixed rod 301 is fixedly installed on the bottom of the lower clamping plate 205, and the connecting plate 302 is fixedly installed on the bottom of the fixed rod 301. The two movable rods 303 are movably connected to the left and right sides of the bottom of the connecting plate 302. The movable rod 303 is movably connected to the front of the mounting plate 9 through a rotating shaft. On the side, the two movable blocks 304 are movably connected to the outer side of the movable rod 303, the two support plates 305 are fixedly installed on the top of the two movable blocks 304, the two electric transmission belts 306 are fixedly installed on the top of the two support plates 305, movable grooves 307 are opened on the left and right sides of the top of the workbench 1, the two electric transmission belts 306 are movably connected in the inner cavity of the movable groove 307, a movable groove 308 is opened at the middle end of the top of the workbench 1, the fixed rod 301 is slidably connected in the inner cavity of the movable groove 308, the left and right sides of the bottom of the four support rods 4 are fixedly installed with base plates 5, and the front and rear sides of the top of the two base plates 5 are threadedly connected with anchor bolts 6.

[0035] By setting a limit rod 209, the moving direction of the upper clamping plate 208 and the lower clamping plate 205 can be limited to avoid deviation during movement, which will make it impossible to clamp the sack. By setting a sliding rod 210, the movement of the second tooth plate 206 and the first tooth plate 203 can be limited to avoid deviation during movement, which will affect the clamping of the sack. By setting a fixed rod 301 and a movable rod 303, the electric conveyor belt 306 can be moved up and down, which is convenient for automatically transporting the woven sacks through the electric conveyor belt 306. The movable groove 307 is provided to limit the moving direction of the electric transmission belt 306 to avoid positional deviation during movement, which in turn affects the normal transportation of the sacks. The movable groove 308 is provided to limit the fixed rod 301 to avoid the fixed rod 301 changing direction when driving the connecting plate 302 to move, which in turn affects the normal lifting and lowering of the movable groove 308. The anchor bolt 6 is provided to stabilize the entire device to avoid shaking of the device due to interference from external factors, which in turn affects the normal weaving of the sacks.

[0036] When the utility model is working: the sack is placed on the top of the right electric conveyor belt 306, and then it is transferred to the inner side of the upper clamping plate 208 and the lower clamping plate 205 through the transportation of the electric conveyor belt 306, and then the output end of the motor 201 drives the gear 202 to rotate. With the rotation of the gear 202, the first tooth plate 203 drives the first connecting rod 204 and the lower clamping plate 205 to move upward, and at the same time, the second tooth plate 206 drives the second connecting rod 207 and the upper clamping plate 208 to move downward. With the movement of the lower clamping plate 205, the fixed rod 301 moves upward synchronously. At this time, the movable rod 303 is flipped inward due to the movement of the connecting plate 302, and drives the movable block 304, the support plate 305 and the electric conveyor belt 306 to move downward synchronously. At this time, the sack falls on the top of the lower clamping plate 205, and with the movement of the motor 201 The motor 201 outputs in the reverse direction and causes the gear 202 to rotate in the reverse direction. At this time, the first tooth plate 203 drives the first connecting rod 204 and the lower splint 205 to move toward the bottom, and the second tooth plate 206 drives the second connecting rod 207 and the upper splint 208 to move toward the top, thereby releasing the fixation of the sack. At the same time, with the movement of the lower splint 205, the fixed rod 301 moves downward synchronously and causes the movable rod 303 to flip outward. At this time, the movable rod 303 pushes the movable block 304, the support plate 305 and the electric transmission belt 306 upward to move. The electric transmission belt 306 lifts the sack on the top of the lower splint 205 again and transports the sack out through the electric transmission belt 306 to complete the transportation of the sack.

[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
