Description

Technical Field

[0001] This application relates to the technical field of automatic binding machines, and particularly to an automatic binding machine with an automatically rotating device for a conductive rubber pad and an automatic binding machine. Background Art

[0002] Currently, automatic binding machines sold on the market are all equipped with conductive rubber pads. The function of the conductive rubber pad is to support the punching drill bit after punching through the paper. At the same time, when the punching drill bit touches the conductive rubber pad, an electrical signal can be transmitted through a conductive sheet provided under the conductive rubber pad and fed back to the electronic control device through a wire, thereby controlling the up and down movement of the punching drill bit. However, each time the punching drill bit punches through the paper and contacts the conductive rubber pad, it will cause impact and wear on the conductive rubber pad. And the conductive rubber pad is usually made of a special rubber with a relatively high value. Therefore, users hope to extend its service life as much as possible while maintaining the normal use function of the conductive rubber pad.

[0003] However, most of the existing automatic binding machines have an integral structure for their seat bodies. The conductive rubber pad is embedded in the rubber pad fixing seat. To rotate the conductive rubber pad, one needs to manually touch the control panel to control the rotation of the conductive rubber pad through the machine. Although this function realizes the replacement of the conductive rubber pad without using tools, it still requires manual rotation of the conductive rubber pad through the automatic binding machine, and it is difficult to control the rotation angle of the conductive rubber pad each time. At the same time, there are various types of conductive rubber pad rotations on the market, but their structures are relatively complex, such as ratchet intermittent rotation, single-phase bearing rotation, leaf spring rotation, etc., which greatly increases the production cost of the automatic binding machine.

[0027] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail with reference to the drawings.

[0028] Aiming at the technical problems of complex and high-cost conductive rotating structures on the current market, the present application provides an automatic rotating device with a conductive rubber pad for an automatic binding machine. Please refer to Figure 1 and Figure 2 , which realizes the automatic rotation function of the conductive rubber pad 1 through a simple rotating structure, and can greatly increase the service life of the conductive rubber pad 1 and the binding stability of the automatic binding machine.

[0029] The automatic binding machine with an automatically rotating conductive rubber pad device includes a conductive rubber pad 1, a rubber pad mounting seat 2, a transmission shaft 3, a gear set 4, and a driving motor 5. The output rotating shaft 51 of the driving motor 5 is connected to the transmission shaft 3 through the gear set 4. The conductive rubber pad 1 is installed in the rubber pad mounting seat 2, and the transmission shaft 3 passes through the rubber pad mounting seat 2 and is connected to the axis of the conductive rubber pad 1. The driving motor 5 serves as a power source. The transmission shaft 3 rotates synchronously with the output rotating shaft 51 of the driving motor 5 under the transmission of the gear set 4, thereby driving the conductive rubber pad 1 to rotate relative to the rubber pad mounting seat 2. Therefore, it can prevent the drilling bit of the automatic binding machine from repeatedly hitting the same part of the conductive rubber pad 1, effectively improving the utilization rate of the conductive rubber pad 1, reducing the loss of the conductive rubber pad 1, and extending the service life of the conductor.

[0030] The driving motor 5 is started according to the number of times the drilling bit of the automatic binding machine hits the conductive rubber pad 1. Specifically, in this embodiment, when the number of times the drilling bit hits the same position of the conductive rubber pad 1 reaches 10 times, the driving motor 5 is started and its output rotating shaft 51 rotates 20°. Thereby, the transmission shaft 3 is driven to rotate through the gear set 4, so that the conductive rubber pad 1 connected to the transmission shaft 3 rotates to the next blank area for the drilling bit to hit. That is, by rotating the conductive rubber pad 1, the utilization rate of the conductive rubber pad 1 is improved, without manual rotation by workers, and the loss of the conductive rubber pad 1 is reduced.

[0031] The gear set 4 of this embodiment includes a first gear 41, a second gear 42, and a third gear 43. The second gear is meshed with the first gear 41 and the second gear 42 respectively to realize the transmission between the first gear 41 and the second gear 42 through the second gear 42. The first gear 41 is connected to the output rotating shaft 51 of the driving motor 5, and the third gear 43 is connected to the transmission shaft 3. Thus, when the output rotating shaft 51 of the driving motor 5 rotates, the first gear 41 rotates to drive the second gear 42 to rotate, and the third gear 43 rotates under the transmission of the second gear 42, so that the transmission shaft 3 connected to the third gear 43 rotates, and then the transmission from the driving motor 5 to the transmission shaft 3 is realized through the gear set 4.

[0032] In addition, in this embodiment, a connecting seat 411 is provided at the axis of the first gear 41. A positioning rod 52 is inserted radially at the end of the output rotating shaft 51 of the driving motor 5. The positioning rod 52 is inserted into the connecting seat 411 together with the output rotating shaft 51 of the driving motor 5, so that the first gear 41 rotates synchronously with the output rotating shaft 51 of the driving motor 5. Specifically, the outer contour of the cross-section of the output rotating shaft 51 of the driving motor 5 where the positioning rod 52 is inserted is the same as the hole shape of the insertion hole of the connecting seat 411 on the first gear 41 for the output rotating shaft 51 to be inserted. The positioning connection between the output rotating shaft 51 of the driving motor 5 and the first gear 41 is realized through the cooperation of the positioning rod 52 and the connecting seat 411, which is convenient for installation and disassembly.

[0033] Similarly, the transmission shaft 3 of this embodiment is set as a non-circular shaft. The transmission shaft 3 is connected between the third gear 43 and the conductive rubber pad 1. A connection hole is provided at the center of the conductive rubber pad 1, and a connection sleeve 431 is provided at the center of the third gear 43. The insertion hole for the transmission shaft 3 in the connection hole and the connection sleeve 431 has the same outer contour as the cross-section of the transmission shaft 3, so as to realize the synchronous rotation of the conductive rubber pad 1 and the third gear 43 through the transmission shaft 3. In a specific embodiment, the transmission shaft 3 can be set as a triangular prism, a square prism, a hexagonal prism or other special-shaped columns, etc., and the insertion holes for the transmission shaft 3 in the connection hole and the connection sleeve 431 can be correspondingly set as triangular holes, square holes, hexagonal holes or other special-shaped holes.

[0034] In addition, a housing 44 for mounting the gear set 4 is provided outside the gear set 4. The housing 44 includes a gear upper cover 441 and a gear lower cover 442. The gear lower cover 442 is provided with a plurality of positioning holes 443. The number of the positioning holes 443 is not less than the number of gears in the gear set 4, and a positioning post (not shown in the figure) is provided at the center of each gear of the gear set 4. The radial position of the gear is positioned by inserting the positioning post into the positioning hole 443. By restricting the radial displacement of the gear, the meshing stability between adjacent gears is ensured, and the stability of the gear transmission of the gear set 4 is ensured. The gear upper cover 441 is provided with a plurality of through holes 444. The output rotating shaft 51 of the driving motor 5 and the transmission shaft 3 can penetrate into the housing 44 through different through holes 444 to be connected to the first gear 41 and the third gear 43 respectively. The gear set 4 is encapsulated in the housing 44, which can play a role in limiting and protecting the gears.

[0035] The gear upper cover 441 and the gear lower cover 442 are detachably connected before, so as to facilitate the assembly of the gear set 4 into the housing 44, and the gear upper cover 441 and the gear lower cover 442 are fixedly connected by screws, which is convenient for installation and disassembly.

[0036] The conductive rubber pad 1 is installed in the rubber pad mounting seat 2. The rubber pad mounting seat 2 is provided with a mounting groove 21 for placing the conductive rubber pad 1. The groove diameter of the mounting groove 21 is slightly larger than the outer diameter of the conductive rubber pad 1, and the groove depth of the mounting groove 21 is greater than the thickness of the conductive rubber pad 1, so that the conductive rubber pad 1 can be embedded in the mounting groove 21 to support, limit and protect the conductive rubber pad 1. A notch 22 is provided on the side of the conductive rubber pad 1, and the worker can take out the conductive rubber pad 1 from the mounting groove 21 through the notch 22 to facilitate the replacement of the conductive rubber pad 1.

[0037] Meanwhile, a channel 23 is also provided on the rubber pad mounting seat 2. The conductive sheet 6 of the automatic binding machine is disposed below the conductive rubber pad 1. The conductive sheet 6 is used to conduct the electrical signal of the punching drill bit, enabling normal signal transmission between various components of the machine. The function of the conductive rubber pad 1 is to support the punching drill bit after punching through the paper. At the same time, when the drill bit touches the conductive rubber pad 1, an electrical signal can be transmitted to the conductive sheet 6, and then fed back to the electronic control device through a wire, thereby controlling the up and down movement of the drill bit. The conventional conductive sheet 6 includes an annular mounting portion and a strip-shaped extension portion. The mounting portion and the extension portion are integrally formed of a metal material, and the extension portion can pass through the channel 23 to penetrate the rubber pad mounting seat 2 for connection with other conductive components.

[0038] This application further includes a detection element and a reminder module. The detection element is used to monitor the rotation times of the conductive rubber pad 1. The detection element sends the real-time monitored times information to the control unit of the automatic binding machine. When the accumulated rotation times of the conductive rubber pad 1 reach the set times, the control unit sends a control signal to the reminder module to make the reminder module send a reminder signal for replacing the conductive rubber pad 1. In this embodiment, the reminder module uses a speaker. When the accumulated rotation times of the conductive rubber pad 1 reach the set times, the speaker will emit a voice prompt of "Please replace the conductive rubber pad".

[0039] In summary, when the punching times of the punching drill bit of the automatic binding machine accumulate to the set times, the conductive rubber pad 1 can be driven by the driving motor 5 and rotate to the next unstruck position under the transmission action of the gear set 4 and the transmission shaft 3. That is, this application uses the driving motor 5 as the power source and uses the gear set 4 and the transmission shaft 3 to realize the transmission between the driving motor 5 and the conductive rubber pad 1 to realize the rotation of the conductive rubber pad 1, so that the punching drill bit of the automatic binding machine can strike different positions of the conductive rubber pad 1, effectively improving the utilization rate of the conductive rubber pad 1, reducing the loss of the conductive rubber pad 1, and prolonging the service life of the conductive rubber pad 1. And the rotation of the conductive rubber pad 1 is realized by the driving motor 5 according to the punching times of the punching drill opening, realizing the intelligence of the automatic binding machine, and the rotation angle control accuracy is high.

[0040] When the accumulated rotation times of the conductive rubber pad 1 reach the set times, the reminder module can also timely send a reminder voice for replacing the conductive rubber pad 1 to remind the worker, improving work efficiency, and also avoiding the situation of damage caused by the direct rigid contact between the punching drill bit and the conductive sheet 6 due to the damage of the conductive rubber pad 1, which is also beneficial to prolonging the service life of the automatic binding machine.

[0041] The structure of the automatic binding machine with a conductive rubber pad automatic rotation device in this application is simple, convenient to assemble, reduces the equipment cost, and has a high degree of intelligence.

[0042] The present application also discloses an automatic binding machine, which includes the automatic rotating device of the conductive rubber pad of the automatic binding machine as described above. By adopting the automatic rotating device of the conductive rubber pad of the automatic binding machine, it also has the beneficial effects of the automatic rotating device of the conductive rubber pad of the automatic binding machine as described above, that is, the service life of the conductive rubber pad 1 is extended, ensuring the normal use of the automatic binding machine. And the automatic rotating device of the conductive rubber pad of the automatic binding machine in the present application adopts a simple combination of gear sets 4 to realize the automatic rotation of the driving motor 5 driving the conductive rubber pad 1. The structure is simple and easy to design, with fewer components used and lower costs.

[0043] The above are only some embodiments of the present application. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present application, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present application.
