DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0031] See also Figure 1-Figure 5The utility model provides a technical solution: a wrapping tape tension control device for a wrapping machine, comprising a bracket 1 and a discharge tray 4 for winding the wrapping tape, a connecting seat 2, which is arranged at the upper end of the bracket 1, and the discharge tray 4 is rotatably connected to the connecting seat 2, preferably connected by a bearing; specifically, the wrapping tape tension control device also includes a rotating shaft 3, one end of which is rotatably arranged on the connecting seat 2, and the other end of the rotating shaft 3 passes through a slot opened in the discharge tray 4; a positioning pin 6, which is arranged in a positioning hole 5 opened on one side of the discharge tray 4, and one end of the positioning pin 6 is screwed into the pin hole opened in the rotating shaft 3; at least one device A sleeve 9 on one side of the connecting seat 2, wherein a movable groove 13 is provided inside the sleeve 9, and a movable rod 12 is slidably provided in the movable groove 13; an elastic member 14 is provided at the bottom end of the movable groove 13 and contacts one end of the movable rod 12; in this embodiment, the elastic member 14 is a spring; a contact 15 is provided at the other end of the movable rod 12; a damping plate 17 is provided on the side of the discharge plate 4 that fits the contact 15, and a concave hole 18 is provided on the surface of the damping plate 17, and after the contact 15 enters the concave hole 18, it contacts the inner wall of the concave hole 18; a slideway 19 is connected between adjacent concave holes 18;

[0032] The above technical solution can ensure that the discharge tray 4 has a damping effect when it rotates. When the discharge tray 4 rotates, it will drive the damping disk 17 on its side to rotate. The recessed hole 18 on the surface of the damping disk 17 constantly contacts the contact 15. The contact 15 pushes the movable rod 12 to slide in the movable groove 13, and the elastic member 14 pushes the movable rod 12 to reset. The elastic member 14 can keep the ball 16 and the damping disk 17 in contact at all times, thereby producing a damping effect on the rotation of the discharge tray 4, ensuring that the wrapping tape on the surface of the discharge tray 4 maintains sufficient tension. Since the elastic member 14 and the contact 15 cooperate with the recessed hole 18 to achieve damping, compared with direct friction deceleration, the wear of the contact 15 can be minimized as much as possible, thereby increasing the service life of the device.

[0033] Further, such as Figure 5 As shown, the wrapping tape tension control device of the wrapping machine further includes a ball 16, which is arranged in a groove opened in the contact 15, and the ball 16 is in contact with the concave hole 18;

[0034] The above technical solution can further reduce the wear of the contact 15. When the discharge tray 4 rotates, it will drive the damping plate 17 on its side to rotate. The concave holes 18 on the surface of the damping plate 17 continuously collide with and separate from the ball 16, and the ball 16 intermittently drives the contact 15 to move.

[0035] like Figure 2As shown, the wrapping tape tension control device of the wrapping machine also includes an adjustment structure for adjusting the distance between the sleeve 9 and the damping plate 17 to change the pressure of the elastic member 14 on the contact 15; specifically, the adjustment structure includes an electric push rod 7, the bottom of which is fixed in the connecting seat 2, and the output end of the electric push rod 7 is connected to a movable plate 8, and the movable plate 8 is connected to the sleeve 9;

[0036] The above technical solution can be used to adjust the damping size as needed to change the tension of the wrapping tape. When the tension needs to be increased, the electric push rod 7 is started, and the electric push rod 7 drives the movable plate 8 to move close to the damping disk 17. The movable plate 8 pushes the sleeve 9, and the sleeve 9 squeezes the elastic member 14, thereby increasing the damping effect between the ball 16 and the damping disk 17, and increasing the tension of the wrapping tape.

[0037] like Figure 5 As shown, the wrapping tape tension control device of the wrapping machine also includes a threaded rod 10, which is arranged at the bottom of the sleeve 9, and the threaded rod 10 cooperates with a threaded groove 11 opened on the surface of the movable plate 8; a cover plate 20 is threadedly connected to the opening of the connecting seat 2, and a through hole 21 for the contact 15 to pass through is opened on the surface of the cover plate 20;

[0038] The above technical solution can be used to facilitate the replacement of the sleeve 9. When maintenance is required, the positioning pin 6 is taken out, the discharge tray 4 is pulled out from the rotating shaft 3, the cover plate 20 is rotated to remove it from the connecting seat 2, and then the sleeve 9 is rotated. The sleeve 9 drives the threaded rod 10 to rotate synchronously until the threaded rod 10 is separated from the threaded groove 11 of the movable plate 8, so that the sleeve 9 can be disassembled and the fatigued elastic part 14 and the worn ball 16 can be replaced and maintained.

[0039] Working principle: When in use, when the discharge tray 4 rotates, it will drive the damping disk 17 on its side to rotate, and the concave hole 18 on the surface of the damping disk 17 will constantly conflict with and separate from the ball 16, and the ball 16 will intermittently drive the contact 15 to move, and the contact 15 will push the movable rod 12 to slide in the movable groove 13, and the elastic member 14 will push the movable rod 12 to reset, and the elastic member 14 can keep the ball 16 and the damping disk 17 in contact all the time, thereby generating a damping effect on the rotation of the discharge tray 4, ensuring that the wrapping belt on the surface of the discharge tray 4 maintains sufficient tension. When the tension needs to be increased, by starting the electric push rod 7, the electric push rod 7 drives the movable plate 8 to move close to the damping disk 17, and the movable plate 8 pushes the sleeve 9, and the sleeve 9 squeezes the elastic member 14, thereby increasing the damping effect between the ball 16 and the damping disk 17 and increasing the tension of the wrapping belt;

[0040] When maintenance is required, remove the positioning pin 6, pull the discharge tray 4 out from the rotating shaft 3, rotate the cover plate 20 to remove it from the connecting seat 2, and then rotate the sleeve 9, which drives the threaded rod 10 to rotate synchronously until the threaded rod 10 is separated from the threaded groove 11 of the movable plate 8, so that the sleeve 9 can be removed and the fatigued elastic part 14 and the worn ball 16 can be replaced and maintained.

[0041] Thereby completing a series of tasks, the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

[0042] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
