Description

Technical Field

[0001] The utility model relates to the technical field of steel strapping machines, in particular to a pressure head positioning device for a steel strapping machine. Background Art

[0002] The steel strapping machine is a machine that uses steel strapping to wrap around products or packages, then presses the tightening button to tighten the excess steel strapping so that the steel strapping fits tightly against the products or packages, and then connects the two sides of the steel strapping by melting it through thermal effects or using materials such as steel buckles.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides a steel strapping machine pressure head positioning device, such as Figure 1-5 As shown, it includes a connecting box 1, a power telescopic rod 2 and a pressure head structure 3. The pressure head structure 3 is located inside the connecting box 1. The pressure head structure 3 will press the steel belt when it is close to the steel belt. The tightened steel belt is located below the connecting box 1. The connecting box 1 is connected to the baler body to connect the two layers of steel belts together. The upper surface of the pressure head structure 3 is fixedly connected to the lower end of the power telescopic rod 2. The power telescopic rod 2 controls the pressure head structure 3 to move downward to press the steel belt below. The upper end of the power telescopic rod 2 is fixedly passed through the inner top wall of the connecting box 1. An inner plate 6 is provided inside the connecting box 1. Two round rods 4 are fixedly inserted inside the connecting box 1. The left and right ends of the inner plate 6 are respectively slidably sleeved on the outer surfaces of the two round rods 4. The round rods 4 limit the movement trajectory of the inner plate 6. The upper surface of the inner plate 6 A fixed shaft 7 is fixedly penetrated, and the fixed shaft 7 is fixedly sleeved on the upper end of the power telescopic rod 2. One end of the fixed shaft 7 located above the inner plate 6 is rotatably sleeved with a synchronous sleeve 8. The fixed shaft 7 is coaxial with the pressure head structure 3 and the synchronous sleeve 8. The upper end of the synchronous sleeve 8 is connected with a transmission structure 5. Slide blocks 9 are slidably inserted on the left and right sides of the connecting box 1. The two slide blocks 9 are rotatably connected to the transmission structure 5. Straight grooves 15 are provided on the left and right sides of the connecting box 1. The two slide blocks 9 are respectively slidably inserted in the inside of the two straight grooves 15. The straight grooves 15 limit the sliding trajectory of the slide blocks 9. The transmission structure 5 includes a worm gear 51 and a worm 52. The worm gear 51 is fixedly sleeved on the outer surface of the synchronous sleeve 8, and the worm gear 51 is meshed with the worm 52. The two slide blocks 9 are rotatably sleeved on the outer surface of the worm 52.

[0026] The outer surface of the synchronous sleeve 8 is fixedly sleeved with a gear 10, and tooth plates 11 are meshed on the left and right sides of the gear 10. The two tooth plates 11 are arranged in parallel, and the two tooth plates 11 are distributed in an array around the axis of the synchronous sleeve 8. When the gear 10 rotates, the two tooth plates 11 can be driven to move synchronously. The ends of the two tooth plates 11 that are away from each other are fixedly connected with a ridge rod 12, and the lower ends of the two ridge rods 12 are slidably sleeved with side clamps 14. The lower ends of the two side clamps 14 are both right-angled triangle ends, and the sides of the two side clamps 14 that are close to each other are both vertical surfaces. The outer surfaces of the two ridge rods 12 are sleeved with springs 16, and the upper ends of the two springs 16 are respectively connected to The two edge rods 12 are fixedly connected, and the lower ends of the two springs 16 are fixedly connected to the upper surfaces of the two side clamps 14 respectively. When the two side clamps 14 are located on the same side of the steel belt, when pushing the inner plate 6 to move, first make the inclined surface of one side clamp 14 contact the steel belt, so that the side clamp 14 slides on the upper surface of the steel belt through the compression spring 16, and then move between the two side clamps 14 to both sides of the steel belt. The two side clamps 14 are symmetrically distributed front and back with the axis of the synchronous sleeve 8, and the two side clamps 14 are located in the same straight line with the axis of the synchronous sleeve 8.

[0027] The upper surfaces of the two tooth plates 11 are slidably plugged with plug blocks 13, and the two plug blocks 13 are fixedly connected to the upper surface of the inner plate 6. The lower ends of the two side clamping plates 14 slide through the inner bottom wall of the connection box 1. The plug blocks 13 limit the moving trajectory of the tooth plates 11, so that the tooth plates 11 can stably engage with the gear 10 when moving.

[0028] Working principle: push the slider 9 to control the two side clamps 14 to move to both sides of the steel belt. When the worm 52 is rotated, it drives the synchronous sleeve 8 to rotate by meshing with the worm wheel 51. The gear 10 and the synchronous sleeve 8 rotate synchronously and mesh with the two tooth plates 11, driving the two side clamps 14 to approach each other. As the two side clamps 14 approach each other, they gradually contact the side surfaces of the steel belt. When the pressure head structure 3 is misaligned with the steel belt, the side clamps 14 on one side contact the steel belt first. When the two side clamps 14 continue to approach each other, the inner plate 6 is pushed to slide on the round rod 4. When both side clamps 14 contact the two side surfaces of the steel belt, the pressure head structure 3 moves to the center of the steel belt to ensure that the power telescopic rod 2 will not deviate when pushing the pressure head structure 3 to press the steel belt.
