Abstract
Description
Technical Field
[0001] This utility model relates to a packing machine, and more particularly to a sliding plate mechanism of the packing machine core. Background Technology
[0002] The strapping machine includes a core mechanism, which comprises a slide plate mechanism, a top strapping mechanism, and a strapping cutting mechanism. A series of cams mounted on the core shaft are driven by a core motor to control the movement of these mechanisms, thereby securing, cutting, and bonding the strapping. The slide plate, in conjunction with the top blade, acts as a backing pad when the strapping is being topped. Previously, the slide plate required upper and lower slide plates, with the upper slide plate serving as the backing pad. To ensure horizontal movement during sliding, a movable connection was required, resulting in a complex overall structure. Utility Model Content
[0003] The purpose of this utility model is to provide a sliding plate mechanism for a movement, which has a simple structure and stable operation. To this end, this utility model adopts the following technical solution:
[0004] A sliding mechanism for a movement includes a movement frame, a sliding arm, a swing shaft, and a sliding plate. The movement frame has a left and right upright plate, which are perpendicular to the swing shaft. The left and right sides of the swing shaft are connected to the lower parts of the left and right upright plates, respectively. The sliding arm is connected to the swing shaft. The upper ends of the sliding plate and the sliding arm are fixedly connected. A left and right cantilever rod are connected to the left and right sides of the movement frame, respectively. The upper ends of the left and right cantilever rods are cantilevered above the movement and positioned on either side of the sliding plate, and each is provided with a guide rail. The sliding plate has a guiding engagement structure that slides and guides the guide rails on the left and right cantilever rods.
[0005] Based on the above technical solutions, the present invention may also adopt the following further technical solutions, or combine these further technical solutions:
[0006] The movement is provided with a first movement shaft and a second movement shaft. The first movement shaft is close to the first side of the movement frame and the second movement shaft is close to the second side of the movement frame. The slide bar is located on the second side of the movement frame and the swing shaft is located below the first movement shaft. The first movement shaft and the second movement shaft are connected by a transmission mechanism and rotate synchronously. The first movement shaft or the second movement shaft is connected to the movement motor.
[0007] The sliding rocker arm is C-shaped facing the first side of the movement frame. The guide rail is a horizontal motion guide structure. When the sliding rocker arm slides to the position where it engages with the top cutter in the movement, it is in a horizontal state. The sliding rocker arm is perpendicular to the top cutter in the movement. The top cutter is located above the first movement shaft.
[0008] The second mechanism shaft is equipped with a cam that controls the swing of the slide bar.
[0009] The cantilever bar includes a vertical section and an inclined section that slopes upward toward the center of the movement. The vertical section is connected to the inner side of the movement frame, and a guide rail is provided at the end of the inclined section that slopes upward toward the center of the movement.
[0010] The mechanism frame includes a top knife guide frame, the left and right sides of which are connected to the left and right vertical plates, respectively, and the vertical section is connected to the top knife guide frame.
[0011] The return spring of the skateboard arm is connected between the skateboard arm and the vertical section of the cantilever bar.
[0012] The skateboard mechanism contains only one skateboard.
[0013] By adopting the technical solution of this utility model, the skateboard mechanism of this utility model is supported and guided by the cantilever rod, which has a simple structure, makes the skateboard run smoothly, and the structure and force of the cantilever rod are reasonable, which helps to extend the service life and provide better support for the skateboard.

[0019] Referring to the accompanying drawings, the present invention provides a sliding mechanism for a movement, including a movement frame 102, a sliding arm 301, a swing shaft 50, and a sliding plate 300. The movement frame 102 is provided with a left upright plate 1021 and a right upright plate 1022, which are perpendicular to the swing shaft 50. The left and right sides of the swing shaft 50 are respectively connected to the lower parts of the left and right upright plates 1021 and 1022. The sliding arm 301 is connected to the swing shaft 50 and can swing under the control of a control structure. The upper ends of the sliding plate 300 and the sliding arm 301 are fixedly connected. The left and right sides are respectively connected to the left cantilever rod 303 and the right cantilever rod 304. The upper ends of the left cantilever rod 303 and the right cantilever rod 304 are respectively suspended above the movement and located on both sides of the slide plate. The upper ends of the left cantilever rod 303 and the right cantilever rod 304 are provided with guide rails 3041. The slide plate 300 is provided with a guide engagement structure 310 that slides and guides the guide rails 3041 on the left cantilever rod 303 and the right cantilever rod 304. The guide rail 3041 can be a protruding guide rail, and correspondingly, the guide engagement structure 310 is groove-shaped to allow the protruding guide rail to be inserted. The guide rail can also be concave, and the guide engagement structure 310 is a protrusion that can be inserted into the concave guide rail.
[0020] The movement is equipped with a first movement shaft 103 and a second movement shaft 104. The first movement shaft 103 is located near the first side of the movement frame 102, while the second movement shaft 104 is located near the second side of the movement frame 102. The skateboard swing arm 301 is located on the second side of the movement frame 102, and the swing shaft 50 is located below the first movement shaft 103, which helps to allow the skateboard 300 to operate in a basically horizontal manner and cooperate with the guide rail 3041. The first movement shaft 103 and the second movement shaft are connected by a transmission mechanism and rotate synchronously. The first movement shaft 103 or the second movement shaft 104 is connected to the movement motor 101. The second movement shaft 104 is equipped with a cam 302 that controls the swing of the skateboard swing arm 301. Reference numeral 306 is the return spring of the skateboard swing arm 301, which allows the roller 307 on the skateboard swing arm 301 to make close contact with the cam 302.
[0021] As shown in the figure, the sliding rocker arm 301 is C-shaped facing the first side of the movement frame, which neither interferes with the internal structure of the movement nor prevents the swing axis 50 from being located below the first movement axis 103. The guide rail 3041 is a horizontal motion guide structure. When the sliding rocker arm 300 slides to the position where it engages with the top cutter in the movement, it is in a horizontal state. The top cutter is located above the first movement axis 103. The reference numeral 305 is the lifting guide hole for the top cutter.
[0022] The left cantilever rod 303 and the right cantilever rod 304 each include a vertical section 308 and an upward-sloping section 309 towards the center of the movement. This provides the cantilever rods with better stress distribution and support for the slide plate 300. The movement frame 102 includes a top-blade guide frame 1023, which is provided with the lifting guide hole 305. The left and right sides of the top-blade guide frame 1023 are connected to the left upright plate 1021 and the right upright plate 1022. In this embodiment, the vertical section 308 is connected to the top-blade guide frame 1023 in the movement frame 102, and a guide rail 3041 is provided at the end of the upward-sloping section 309. The return spring 306 of the slide plate swing arm is connected between the slide plate swing arm and the vertical section 308 of the cantilever rod, providing better return performance.
[0023] The skateboard mechanism of this utility model contains only one skateboard, namely skateboard 300. The skateboard 300 is fixedly connected to the skateboard swing arm 301 by welding, screw fixing or other methods.
