[0028] like Figure 1-6 As shown, the embodiment of the utility model proposes a closing device for the auxiliary machine of the ZB418 packaging machine, including a knob switch 1 and a contactor 2. A rotating rod 3 is fixed horizontally on the back of the knob switch 1, and the free end of the rotating rod 3 is connected to the contactor 2. The rotation of the knob switch 1 can power on or off the contactor 2 through the rotating rod 3. When the coil of the contactor 2 is energized, the coil current will generate a magnetic field. The generated magnetic field triggers the contactor 2 to attract, and the contactor 2 sends power to the electrical components. A control box is provided on the surface of one end of the rotating rod 3 close to the knob switch 1. The control box is used to control the rotation stroke of the knob switch 1. In this embodiment, the contactor 2 can be selected from the contactor 2 that can be directly purchased on the market. The prior art of its structure has been fully disclosed and will not be elaborated on here.
[0029] The side of the contactor 2 facing the rotary switch 1 is provided with a first, inwardly recessed, circular groove 22. One end of the rotating rod 3 extends into the first groove 22 and is rotatably connected to the contactor 2. A pair of conductive plates 21 are embedded in the sidewalls of the first groove 22, with one conductive plate 21 embedded in the sidewall directly above the groove, and the other conductive plate 21 embedded in the sidewall to the left of the groove. A conductive block 19 is fixedly mounted on the surface of the rotating rod 3 located within the first groove 22. Two conductive strips 20 are provided on the surface of the conductive block 19, corresponding to the conductive plates 21. The conductive plates 21 are electrically connected to the coil of the contactor 2 via wires. When the rotating rod 3 drives the conductive block 19 to rotate, the two conductive strips 20 precisely contact the two conductive plates 21, energizing the coil of the contactor 2.
[0030] The control box includes a first control component and a second control component arranged in sequence along the axial direction of the rotating rod 3. The first control component includes a panel 4 and a first mounting plate 6. The knob switch 1 is rotatably mounted on the front of the panel 4. A second inwardly recessed groove 9 is provided on the back of the panel 4. A disc 5 is rotatably connected in the second groove 9. The axis of the disc 5 coincides with the axis of the rotating rod 3. The first mounting plate 6 is fixed to the back of the panel 4 by bolts. The rotating rod 3 is rotatably passed through the panel 4 and the first mounting plate 6. The disc 5 is fixedly sleeved on the rotating rod 3. A limit assembly for controlling the rotation stroke of the disc 5 is provided on the first mounting plate 6.
[0031] In fact, the limiting components can be two pins. A limiting groove 10 is provided on the edge of the back side of the disc 5. Two through holes are provided on the first mounting plate 6, one of which is located directly above the disc 5, and the other is located on the left side of the disc 5. The two pins are movably inserted into the two through holes. When the disc 5 is rotated, the staff applies an inward force to the pins by hand, and the pins always keep in contact with the disc 5. When the disc 5 is rotated until the limiting groove 10 is connected with the through hole, the pin is inserted into the limiting groove 10 and abuts against the side wall of the limiting groove 10, thereby limiting the rotation of the disc 5. In this embodiment, an inwardly recessed limit groove 10 is provided on the edge of the back of the disk 5. Two arc-shaped through grooves 11 are formed through the first mounting plate 6. The two through grooves 11 correspond to the positions of the limit groove 10 at different rotation angles of the disk 5, that is, one through groove 11 is located above the disk 5, and the other through groove 11 is located to the left of the disk 5. When the disk 5 rotates, the limit groove 10 can communicate with the through groove 11. The limit assembly includes two elastic pressing pieces 12, which correspond one-to-one to the two through grooves 11. One end of the elastic pressing piece 12 is fixedly mounted on the back of the first mounting plate 6 by a bolt, and the other end extends into the corresponding through groove 11 and is used to abut against the groove wall of the limit groove 10. With this structural design, the rotation stroke of the knob switch 1 can only be 90°, thereby limiting the rotation stroke of the knob switch 1.
[0032] The second control assembly includes a second mounting plate 7 and a back plate 8. The back plate 8 is bolted to the back of the second mounting plate 7. The back of the second mounting plate 7 is provided with an inwardly recessed mounting slot 13. The rotating rod 3 is rotatably mounted on the second mounting plate 7 and the back plate 8. The mounting slot 13 contains a locking assembly for controlling the unidirectional rotation of the rotating rod 3 and a switch for eliminating or restoring the locking effect of the locking assembly. The locking assembly includes a ratchet 14 and two pawls 15. The ratchet 14 is fixedly mounted on the rotating rod 3. One end of each pawl 15 is rotatably mounted on the inner wall of the mounting slot 13, and the other end engages with the ratchet 14. The two pawls 15 control the unidirectional rotation of the rotating rod 3 in opposite directions. That is, when one pawl 15 contacts the ratchet 14, the rotating rod 3 can only rotate clockwise, and when the other pawl 15 contacts the ratchet 14, the rotating rod 3 can only rotate counterclockwise. A spring 16 is installed between the pawl 15 and the inner wall of the mounting slot 13. The two ends of the spring 16 are fixedly connected to the inner wall of the mounting slot 13 and the pawl 15, respectively. The spring 16 tends to keep the pawl 15 in contact with the ratchet 14. The switch assembly includes a protrusion 17 and a lever 23. The protrusion 17 is located between the two pawls 15. One end of the lever 23 is fixedly connected to the protrusion 17, and the other end passes through the back plate 8. The lever 23 is rotatably connected to the back plate 8. Rotating the lever 23 drives the protrusion 17, which forces one of the pawls 15 to separate from the ratchet 14. The spring 16 then forces the other pawl 15 to maintain contact with the ratchet 14.
[0033] A damping block is provided at the rotational connection between the lever 23 and the back plate 8. A selection paddle 18 is fixed to the end of the lever 23 outside the back plate 8. The selection paddle 18 is attached to the back of the back plate 8. This structural design facilitates operation. By turning the rotary paddle, the operator can easily control and select which pawl 15 engages with the ratchet wheel 14, that is, the unidirectional rotation direction of the rotating rod 3 and the knob switch 1 can be controlled to rotate clockwise or counterclockwise.
[0034] The surface of the knob switch 1 is provided with an identification mark. In this embodiment, the identification mark "ON" is provided directly above the knob switch 1, indicating that the knob switch 1 is in a normally open state when it is rotated to this position. The identification mark "OFF" is provided on the left side of the knob switch 1, indicating that the knob switch 1 is in a closed state when it is rotated to this position.
[0035] In the above embodiment, the side of the panel 4, disc 5, first mounting plate 6, second mounting plate 7 and back plate 8 facing the knob switch 1 is called the front side, and the side facing the contactor 2 is called the back side. One end of the rotating rod 3 is fixedly connected to the back side of the knob switch 1, and the other end passes through the panel 4, disc 5, first mounting plate 6, second mounting plate 7, ratchet 14 and back plate 8 in sequence and is rotationally connected to the contactor 2. Among them, the connection between the two components, disc 5 and ratchet 14, and the rotating rod 3 is a fixed connection, that is, the rotation of the rotating rod 3 will drive the rotation of the disc 5 and the ratchet 14, while the connection between the panel 4, first mounting plate 6, second mounting plate 7 and back plate 8 and the rotating rod 3 is a rotational connection.
[0036] In the above embodiment, a housing may be provided on the surfaces of the panel 4, the first mounting plate 6, the second mounting plate 7 and the back plate 8 to connect these components into a whole.
[0037] Working principle:
[0038] This utility model replaces the traditional mechanical closing method with a rotary switch 1 and a contactor 2. When the closing conditions are met, turning the normally open rotary switch 1 to the closed position triggers the contactor 2 to close, which then delivers power to the electrical components, achieving high closing efficiency. This device can be operated in two ways: one is to place the rotary switch 1 in the normally open position each time the power is turned off, requiring manual rotation of the rotary switch 1 to close each time the power is turned on. The other is to leave the rotary switch in the closed position each time the power is turned off. This way, the next time the power is turned on, as long as the closing conditions are met, the contactor 2 will automatically close, eliminating the need for manual intervention.
[0039] If it is the first method, the knob switch 1 is in the normally open state, that is, when the power is off, the knob switch 1 points to the top. At this time, the limit slot 10 of the disc 5 is just connected with the through slot 11 located just above the disc 5, and the elastic pressing piece 12 abuts against the side wall of the limit slot 10, so that the disc 5 and the rotating rod 3 cannot continue to rotate clockwise. By toggling the selection paddle 18, the rotating rod 3 can only rotate clockwise. Under the meshing action of the pawl 15 and the ratchet 14, and the elastic pressing piece 12 abuts against the limit slot 10, the knob switch 1 is completely positioned. Due to the structural design, the knob switch 1 will not rotate due to operational errors, accidental touches, etc., and is highly safe to use. When the power needs to be turned on, the selection paddle 18 is toggled so that the rotating rod 3 can only rotate counterclockwise. At this time, the knob switch 1 can be manually rotated to close it. At the same time, under the limiting action of the elastic pressing piece 12 on the left, the knob switch 1 can only rotate 90° counterclockwise, which just makes the knob switch 1 point to the left. The two conductive bars 20 are connected to the two conductive sheets 21, triggering the contactor 2 to attract, and the contactor 2 sends the power supply to the electrical components. The structure is simple and the operation is convenient.
[0040] If the second method is used, the knob switch 1 is in the closed state. At this time, under the action of the left elastic pressure piece 12, the knob switch 1 can only rotate clockwise. At this time, by selecting the paddle 18, the rotating rod 3 can only rotate counterclockwise, and the knob switch 1 can be completely positioned to prevent the knob switch 1 from rotating due to operational errors, accidental touches, etc., thereby improving safety in use.
[0041] The closing device of the auxiliary machine of the ZB418 packaging machine provided by the present invention has at least the following advantages:
[0042] 1. By precisely controlling the rotation angle of the knob switch, it can ensure that each closing operation can be completed quickly and accurately, avoiding the problem of multiple closings caused by low precision of the mechanical transmission device, thereby improving the operating efficiency of the equipment.
[0043] 2. The use of the control box can ensure that the knob switch 1 stays stably at a specific position and will not rotate accidentally due to external factors (such as vibration, impact, accidental touch, etc.), thereby enhancing the stability and reliability of the equipment.
[0044] 3. Simplified operation process: Through the design of the control box, the operator only needs to easily rotate the knob switch 1 to the required position to complete the closing operation, without the need for complicated adjustments or confirmations, which simplifies the operation process and improves work efficiency.
[0045] 4. Since the control box can effectively reduce the risk of wear and damage to the knob switch 1, it can reduce the maintenance cost and repair frequency of the equipment and extend the service life of the equipment.
[0046] 5. The use of the control box can ensure that the knob switch 1 stays safely at a specific position, and will not cause the equipment to lose control or cause a safety accident due to misoperation or other reasons, thereby improving the safety of the equipment.
[0047] 6. The internal components of the control box are designed to be connected by bolts, which are easy to disassemble and adjust, making it convenient for users to adjust and maintain according to actual needs.
[0048] The above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art will appreciate that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and such modifications or equivalent substitutions shall be encompassed by the claims of the present invention.
