[0034] Referring to Figures 1-2 According to the envelope opening mechanism of the first aspect embodiment of the utility model, the envelope opening mechanism includes installation strip 10, installation seat 20 and suction accessory 30.Installation strip 10 has several installation positions, and installation strip 10 is connected with vacuum device (not shown in the figure) ;Installation seat 20 is installed on the installation position of installation strip 10;Suction accessory 30 is movably arranged on installation seat 20 through an adjusting rod 22, and suction accessory 30 is used to adsorb the two sides of envelope opening, and suction accessory 30 is communicated with vacuum device through installation seat 20 and installation strip 10, and adjusting rod 22 is used to adjust the position of suction accessory 30.

[0035] Specifically, the envelope opening mechanism of the utility model embodiment mainly includes installation strip 10, installation seat 20 and suction accessory 30 three major parts.Installation strip 10 is the basis of the whole mechanism, it has several installation positions, for installing multiple installation seats 20.Installation strip 10 is connected with vacuum device, provides necessary vacuum suction force for suction accessory 30.Installation seat 20 is installed on the installation position of installation strip 10, for fixing and supporting suction accessory 30.The design of installation seat 20 makes suction accessory 30 can be conveniently installed and disassembled, and simultaneously guarantees the communication between suction accessory 30 and vacuum device.Suction accessory 30 is the part directly contacting with envelope, and is used to adsorb the two sides of envelope opening.Suction accessory 30 is movably arranged on installation seat 20 through an adjusting rod 22, which makes the position of suction accessory 30 can be flexibly adjusted according to the specific model, size and material of envelope.

[0036] When envelope needs to be opened, first, according to the model, size and material of envelope, the position of suction accessory 30 is adjusted through adjusting rod 22, so that it is closely attached to the two sides of envelope opening.Then, vacuum device is started, and vacuum suction force is provided for suction accessory 30 through installation strip 10 and installation seat 20, so that suction accessory 30 tightly adsorbs the two sides of envelope opening.Under the action of suction force, envelope opening is stably opened, so that the data such as card, instruction manual is conveniently sent into envelope.The key of the envelope opening mechanism of the embodiment lies in the adjustability of suction accessory 30.Through adjusting rod 22, the position of suction accessory 30 on installation seat 20 can be conveniently adjusted, so that the compatibility of different models, sizes and materials of envelope is realized.The design of adjusting rod 22 makes the adjustment process simple and fast, and greatly improves the production efficiency.

[0037] By adjusting the position of the suction accessory 30, various types, sizes and materials of envelopes can be adapted, avoiding the phenomenon of blocking caused by changes in envelope parameters. The design of the adjusting rod 22 makes the position adjustment of the suction accessory 30 simple and fast, reducing the operation difficulty and labor intensity. Since it can stably open the openings of various types of envelopes, it avoids production interruption and blocking phenomenon, thereby improving production efficiency.

[0038] Therefore, it can be understood that the envelope opening mechanism according to the embodiments of the present application has at least the following beneficial effects: through the adjustment of the adjusting rod 22, the position of the suction accessory 30 can be adjusted according to the size and shape of the envelope opening, and then the envelope opening mechanism can be compatible with various types of envelopes, completely open the envelope opening, and finally ensure smooth feeding and improve production efficiency.

[0039] More specifically, with reference to Figures 1-3 In some embodiments of the present application, the mounting seat 20 includes a rotating head 21, which is rotatably arranged at the mounting position of both ends of the mounting strip 10, and the suction accessory 30 is movably arranged on the rotating head 21 through the adjusting rod 22, and the rotating head 21 is used to suck the edge of the opening of the envelope.

[0040] The mounting seat 20 further includes a rotating head 21. The rotating head 21 is rotatably arranged at the mounting position of both ends of the mounting strip 10. The design of the rotating head 21 allows the suction accessory 30 to not only adjust the position through the adjusting rod 22 when sucking the envelope opening, but also adapt to different angles and shapes of the envelope opening through the rotation of the rotating head 21. The suction accessory 30 is movably arranged on the rotating head 21 through the adjusting rod 22. This means that in addition to the linear displacement adjustment provided by the adjusting rod 22, the suction accessory 30 can also realize more complex motion trajectories through the rotation of the rotating head 21, thereby more accurately fitting the edge of the envelope opening. This design greatly improves the adaptability of the envelope opening mechanism to different types, sizes and materials of envelopes. The rotating head 21 is mainly used to suck the edge of the envelope opening. During the envelope opening process, the rotating head 21 can rotate with the shape and angle of the envelope, ensuring that the suction accessory 30 always closely fits the edge of the envelope opening. This close fit not only improves the suction effect, but also avoids the phenomenon of incomplete envelope opening or blocking caused by unstable suction.

[0041] When the envelope needs to be opened, first, according to the type, size and material of the envelope, the position of the suction accessory 30 on the rotating head 21 is adjusted by adjusting the rod 22 to roughly align with the edge of the envelope opening. Then, the vacuum device is started to provide the suction accessory 30 with a vacuum suction force through the mounting strip 10, the mounting seat 20 and the rotating head 21. Under the action of the suction force, the suction accessory 30 tightly adsorbs the edge of the envelope opening. At this time, if further adjustment of the position or angle of the suction accessory 30 is needed, it can be achieved by rotating the rotating head 21. Finally, under the stable adsorption of the suction accessory 30, the envelope opening is completely opened, and the card, instructions and other materials are conveniently sent into the envelope.

[0042] Further, with reference to Figures 1-3 In some embodiments of the present application, the rotating head 21 is provided with a sliding hole 211, and the adjusting rod 22 is slidably arranged in the sliding hole 211. One end of the adjusting rod 22 is connected to the suction accessory 30, and the other end of the adjusting rod 22 is connected to the vacuum device.

[0043] On the basis of the above-mentioned embodiments, a sliding hole 211 is arranged on the rotating head 21. The design of this sliding hole 211 allows the adjusting rod 22 to be slidably arranged therein, thereby realizing the position adjustment of the suction accessory 30 on the rotating head 21. The shape and size of the sliding hole 211 are matched with the adjusting rod 22, which ensures that the adjusting rod 22 can stably slide in the sliding hole 211, and at the same time, it will not produce excessive shaking or deviation due to sliding. One end of the adjusting rod 22 is connected to the suction accessory 30, and the other end of the adjusting rod 22 is connected to the vacuum device. This connection mode makes the adjusting rod 22 not only be able to transmit the vacuum suction force to the suction accessory 30, but also be able to adjust the position of the suction accessory 30 on the rotating head 21 by sliding. The connection between the adjusting rod 22 and the suction accessory 30 and the vacuum device adopts a reliable and easy-to-disassemble mode, such as threaded connection, buckle connection, etc., so as to be replaced or repaired when needed.

[0044] When the position of the suction accessory 30 needs to be adjusted, the adjusting rod 22 is only needed to be manually or by a mechanical device to slide in the sliding hole 211, so as to realize the position adjustment of the suction accessory 30 on the rotating head 21. Since the adjusting rod 22 is connected with the vacuum device, therefore, during the adjustment process, the vacuum suction force is always maintained on the suction accessory 30, which ensures that the suction accessory 30 can stably adsorb the edge of the envelope opening.

[0045] With reference to Figure 1 and Figure 3In some embodiments of the present invention, further, the rotating head 21 is further provided with a fixed knob 212, which is screwed onto the rotating head 21, and the adjusting rod 22 is fixed to the rotating head 21 via the fixed knob 212. A fixed knob 212 is provided on the rotating head 21. This fixed knob 212 is screwed onto the rotating head 21, and can be rotated to tighten or loosen its grip on the adjusting rod 22. The design of the fixed knob 212 enables the adjusting rod 22 to be firmly fixed to the rotating head 21 after being adjusted to a suitable position, thereby preventing the position of the adjusting rod 22 from being shifted due to vibration or external force during the production process.

[0046] Therefore, it is also understandable that, referring to Figure 3 In some embodiments of the present invention, the adjustment rod 22 has a butting plane 221, and the inner end of the fixed knob 212 butts against the butting plane 221. This butting plane 221 is the part that contacts the inner end of the fixed knob 212, and is used to withstand the butting force of the fixed knob 212, thereby ensuring the stability of the adjustment rod 22 under the action of the fixed knob 212. The design of the butting plane 221 enables the adjustment rod 22 to more evenly distribute the force when it is tightened by the fixed knob 212, thereby avoiding deformation or damage caused by uneven force. In addition, since the shape and size of the sliding hole 211 match those of the adjustment rod 22, it ensures that the adjustment rod 22 can slide stably in the sliding hole 211, and at the same time will not produce excessive rotation due to sliding. Therefore, this design makes the fit between the fixed knob 212 and the adjustment rod 22 tighter, improving the stability and reliability of the envelope opening mechanism.

[0047] Reference Figures 1-2 as well as Figure 4 In some embodiments of the present invention, the mounting seat 20 also includes a fixed head, which is arranged in the middle of the mounting strip 10, and the fixed head is used to adsorb the middle of the opening of the envelope. In the middle of the mounting strip 10, the mounting seat 20 in this embodiment also includes a fixed head. This fixed head is firmly connected to the mounting strip 10 to ensure that it will not fall off or shift due to vibration or external force during the production process. The fixed head is designed to adsorb the middle of the envelope opening and cooperate with the adsorption member 30 to achieve stable adsorption and opening of the envelope opening. When the envelope is conveyed to the envelope opening mechanism, the fixed head will be accurately positioned in the middle of the envelope opening and tightly adsorbed by vacuum suction. This design allows the envelope to remain stable during the opening process, avoiding incomplete opening or blockage due to shaking or deviation of the envelope.

[0048] In the envelope opening process, first according to the model, size and material of the envelope, adjust the position of the suction accessories 30 through the adjusting rod 22, so that they can be accurately positioned at the edge and middle of the envelope opening. Then, start the vacuum device, and provide vacuum suction for the suction accessories 30 and the fixing head through the mounting strip 10 and the mounting seat 20. Under the action of the vacuum suction, the suction accessories 30 and the fixing head will tightly adsorb the edge and middle of the envelope opening, so as to completely open the envelope opening. Finally, send the card function, instruction manual and other materials into the envelope, and complete the filling and sealing process of the envelope.

[0049] In some embodiments of the present application, the mounting seat 20 is detachably mounted on the mounting strip 10 by screws. The mounting seat 20 is detachably mounted on the mounting strip 10 by screws. This design enables the mounting seat 20 to be firmly fixed on the mounting strip 10, and can be easily detached when needed. The screw connection has the advantages of simple structure, reliable connection and easy disassembly, and is very suitable for the connection between the mounting seat 20 and the mounting strip 10 in the envelope opening mechanism.

[0050] Referring to Figures 1-2 In some embodiments of the present application, the mounting seat 20 is communicated with the vacuum device through the air pipe joint 11. In the mounting seat 20, the mounting seat 20 of the present embodiment is provided with an air pipe joint 11. This air pipe joint 11 is a key component for connecting the mounting seat 20 and the vacuum device, which ensures that the negative pressure generated by the vacuum device can be smoothly transmitted to the suction accessories 30 on the mounting seat 20, so as to realize stable adsorption of the envelope opening.

[0051] Referring to Figure 1 And Figures 3-4 In some embodiments of the present application, the suction accessories 30 are organ type suction cups. When the vacuum device is started, it will generate negative pressure, and this negative pressure is transmitted to the organ type suction cup through the air pipe and the air pipe joint 11. Under the action of the negative pressure, the petals of the organ type suction cup will tightly adhere to the edge of the envelope opening, forming stable adsorption force. Since the organ type suction cup has multiple petals, it can better adapt to the envelope openings of different shapes and sizes, and ensure the stability and reliability of adsorption.

[0052] According to the second aspect of the utility model discloses an envelope opening device (not shown in the drawing), the envelope opening device includes the envelope opening mechanism of any one embodiment of the above first aspect, the envelope opening device still includes driving part, and the envelope opening mechanism is installed on the output end of driving part through mounting strip 10, and driving part is used to drive the envelope opening mechanism to be away from or close to the envelope opening.
