Description

Technical Field

[0001] The utility model relates to the technical field of travel switches, in particular to a sliding slot and slider type travel switch device. Background Art

[0002] First of all, the travel switch can accurately control the movement position or stroke of the feeding equipment. For example, in a centrifugal feeder, by setting the position of the travel switch, it can ensure that the feeding plate starts or stops feeding at a specific position, thereby achieving precise control of the feeding area and feeding amount. Similarly, for a drop-type feeder, the travel switch can control the movement of the feeding mechanism to ensure that the feed falls at the correct position and time.

[0003] The limit switch uses the collision of the moving parts of the production machinery to move its contacts, thereby connecting or disconnecting the control circuit to achieve a specific control purpose. It is usually used to limit the position or stroke of mechanical movement, so that the moving machinery can automatically stop, reverse, change speed or automatically reciprocate according to the set position or stroke.

[0004] However, most of the existing travel switch structures detect moving objects. Once the detected object exceeds the detection position of the travel switch, the travel switch cannot block it, resulting in continuous feeding of materials. In addition, blockage or accumulation of materials at the discharge port during feeding will cause the feeding equipment to be in an overloaded operating state, and the safety of the feeding equipment cannot be guaranteed. In addition, the distance of the travel switch cannot be adjusted at all times. Utility Model Content

[0013] In a further embodiment, the pawl is movably mounted on the connecting plate, and the two ends of the connecting rod are movably connected to the rack and the left and right screw rods respectively.

[0014] Beneficial effects: The utility model discloses a slide slot slider type travel switch device. The utility model adjusts the position of the slider through the left and right screw rods, and then adjusts the position of the baffle in the slide slot. According to the position change of the baffle, the limitation of the feeding position is controlled. When the weight of the feeding reaches the pressure of the torsion spring on the baffle, the baffle is in an open state, so that the feeding is transferred to the adjacent baffle. The pawl engages or separates with the ratchet wheel to realize the movement of the connecting plate along the rack in one direction or two directions. When the pawl engages with the ratchet wheel, moving the slider will cause the baffle to tilt at a certain angle, thereby meeting different usage scenarios of the baffle. When accumulation occurs during the feeding process and the baffle is in an open state, the rack will be squeezed. When the pawl is separated from the ratchet wheel, the rack approaches the left and right screw rods, thereby expanding the feeding path and reducing blockage. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The utility model adopts a slideway slider type travel switch device, which adjusts the position of the slider through left and right screw rods, and then adjusts the position of the baffle in the slideway. According to the change of the position of the baffle, the limitation of the feeding position is controlled. When the weight of the feeding reaches the pressure of the torsion spring on the baffle, the baffle is in an open state, so that the feeding is transferred to the adjacent baffle. The specific description of the scheme is given below through specific embodiments.

[0024] Reference Figure 1-Figure 7 A sliding slot and slider type travel switch device is shown, comprising:

[0025] A slide groove 100, a slider 101 placed in the slide groove 100, and left and right screw rods 1 passing through the slide groove 100 and the slider 101. Multiple sliders 101 are provided on the left and right screw rods 1. The multiple sliders 101 are arranged in the same direction. The sliders 101 are threadedly matched with the left and right screw rods 1. The left and right screw rods 1 are movably connected to the slide groove 100. A motor is provided at one end of the left and right screw rods 1. The motor is installed at one end of the slide groove 100. The slider 101 adjusts its position in the slide groove 100 under the rotation of the left and right screw rods 1.

[0026] The slider 101 is also provided with a connecting plate 6, which is hinged to the slider 101, and the slider 101 is slidably matched with the slide groove 100. A return spring 3 is also provided between the connecting plate 6 and the slider 101, and the two ends of the return spring 3 are respectively movably connected to the slider 101 and the connecting plate 6. A torsion spring and a movable plate 21 are provided between the connecting plate 6 and the baffle 2. The torsion spring is arranged at the movable connection between the baffle 2 and the movable plate 21. The baffle 2 extends a certain distance out of the slide groove 100. The torsion spring applies a force to the baffle 2. When the baffle 2 is subjected to sufficient force, the baffle 2 opens.

[0027] The two ends of the movable plate 21 are respectively movably connected with the connecting plate 6 and the baffle 2. The movable plate 21 is provided with a ratchet 22 at the position of the connecting plate 6. The ratchet 22 and the gear 23 are both hinged to the movable plate 21. The pawl 24 is movably mounted on the connecting plate 6, and the pawl 24 meshes with the ratchet 22. The movable plate 21 is provided with a gear 23 at the position of the baffle 2. A rack 4 is also provided between the ratchet 22 and the gear 23. The gear 23 and the ratchet 22 are both meshed with the rack 4. The two ends of the rack 4 are also provided with connecting rods 5 connected to the left and right screw rods 1. The two ends of the connecting rod 5 are respectively movably connected to the rack 4 and the left and right screw rods 1.

[0028] Working principle description: First, the chute 100 is set on both sides of the material conveying channel. When the put material contacts the baffle 2 and the weight does not reach the requirement, the baffle 2 limits the position of the material. When the put material continues to be at the position of the baffle 2, the baffle 2 opens and transfers the material. During the transfer process, the baffle 2 is reset under the action of the torsion spring to limit the position of the material again.

[0029] When the position of the slider 101 needs to be adjusted, the ratchet 22 and the pawl 24 are separated, and the motor rotates the left and right screw rods 1, so that the sliders 101 on the left and right screw rods 1 move in opposite directions, and the adjustment of the travel switch of the baffle 2 is completed;

[0030] When the baffle 2 is in the open state and the released materials are accumulated on both sides of the conveying channel, the rack 4 is squeezed and moves towards the slider 101. Under the active connection between the connecting rod 5, the rack 4 and the left and right screw rods 1, and the active connection between the connecting plate 6 and the slider 101, the rack 4 is close to the slider 101. At this time, the channel for releasing materials is widened and the blockage phenomenon is alleviated.
