[0035] The above scheme, refer to the attached Figure 3 As shown in the figure, limit component 7 includes limit plate 71, guide rod 72, slider 73, abutting plate 74 and spring 75;Limit plate 71 is set on main mounting panel 1 and is close to drive motor 4, limit plate 71 is provided with guide rod 72, guide rod 72 is horizontally slidably provided with slider 73, slider 73 is provided with abutting plate 74 for contacting with limit seat 6, and slider 73 and limit plate 71 are connected with spring 75 sleeved on the outside of guide rod 72.
[0036] In the scheme, when vice mounting panel 2 moves to limit plate 71 direction under the action of drive motor 4 and gear 5 rack 3, limit seat 6 of vice mounting panel 2 tail end will gradually approach abutting plate 74, once limit seat 6 contacts with abutting plate 74, with vice mounting panel 2 continues to move, abutting plate 74 will push slider 73 to slide on guide rod 72 to limit plate 71 direction, thereby compressing spring 75 sleeved on the outside of guide rod 72, spring 75 is compressed and will produce elastic force, this elastic force will produce a reverse resistance to the movement of vice mounting panel 2, play the role of buffering, avoid rigid collision between limit seat 6 and abutting plate 74, protect the equipment structure from being damaged, when spring 75 is compressed to the limit state, at this time, slider 73 cannot continue to slide to limit plate 71 direction, abutting plate 74 tightly abuts against limit seat 6, prevents vice mounting panel 2 from further moving, thereby realizes the limitation of vice mounting panel 2's maximum moving stroke, ensures the accuracy and stability of limit component 7 work.

[0038] In the scheme, when the auxiliary mounting plate 2 moves, the limiting seat 6 pushes the abutting plate 74 to make the sliding block 73 slide to the limiting plate 71 direction, the abutting plate 74 will contact and apply pressure to the pressure sensor 76, the pressure sensor 76 can sense the pressure in real time, and convert the pressure signal into an electric signal, when the pressure value detected by the pressure sensor 76 reaches the set pressure value, it means that the auxiliary mounting plate 2 has moved to the maximum stroke, at this time the pressure sensor 76 will send an electric signal to the driving motor 4, and the driving motor 4 will stop running after receiving the signal, so as to prevent the auxiliary mounting plate 2 from continuing to move, realize accurate limiting control, avoid equipment damage or safety hazards caused by excessive movement, and further improve the safety and reliability of the equipment structure.
[0039] In the above scheme, considering the moving effect of the auxiliary mounting plate 2 in the sliding groove 11, in order to further improve the smoothness of the movement of the auxiliary mounting plate 2, referring to the accompanying drawings Figure 4 As shown in the figure, a plurality of balls 12 are installed on the inner wall of the sliding groove 11 to form a rolling channel, and the auxiliary mounting plate 2 is inserted into the rolling channel.
[0040] In the scheme, when the auxiliary mounting plate 2 moves in the sliding groove 11, the friction between the auxiliary mounting plate 2 and the inner wall of the sliding groove 11 is the main factor hindering its smooth movement. By installing a plurality of balls 12 on the inner wall of the sliding groove 11 to form a rolling channel, and inserting the auxiliary mounting plate 2 into the rolling channel, the original sliding friction between the auxiliary mounting plate 2 and the inner wall of the sliding groove 11 is converted into rolling friction. The balls 12 roll between the auxiliary mounting plate 2 and the inner wall of the sliding groove 11, so that the contact points between the auxiliary mounting plate 2 and the sliding groove 11 change constantly, reducing the direct friction between them, thereby reducing the friction, enabling the auxiliary mounting plate 2 to move more smoothly in the sliding groove 11, ultimately reducing the load of the driving motor 4, prolonging the service life of the driving motor 4 and other related components, and avoiding problems such as poor extension or precision decline caused by component wear.
[0041] In the above scheme, considering the problem of dust accumulation in the sliding groove 11, referring to the accompanying drawings Figure 5 As shown in the figure, the limiting seat 6 is provided with a rubber block 61, which is inserted into the sliding groove 11 and is in close contact with the inner wall of the sliding groove 11.
[0042] In the scheme, the rubber block 61 forms a close contact between the rubber block 61 and the inner wall of the sliding groove 11 during movement. When dust or other small particles accumulate in the sliding groove 11, the rubber block 61 acts like a sweeper, scraping off the dust and other impurities on the inner wall of the sliding groove 11, preventing dust from accumulating in the sliding groove 11, thereby cleaning the sliding groove 11.
[0043] In one of the above schemes, referring to the accompanying drawings Figure 1As shown, the chute 11 is open at the front end and closed at the tail end, so that the auxiliary mounting plate 2 has a tail end limit when it is retracted to the initial state.
[0044] In the scheme, when the auxiliary mounting plate 2 moves along the chute 11 under the action of the driving motor 4, the gear 5 and the rack 3, the auxiliary mounting plate 2 can be extended forward due to the open front end of the chute 11, realizing the extension adjustment of the cantilever belt conveyor, and when it is necessary to retract the auxiliary mounting plate 2 to the initial state, the closed structure at the tail end of the chute 11 plays a limiting role, and as the auxiliary mounting plate 2 moves backward, it will be blocked by the closed structure at the tail end when it reaches the tail end of the chute 11, and cannot continue to move backward, thereby accurately returning to the initial position, realizing the limitation of the retraction position of the auxiliary mounting plate 2.
[0045] In the above scheme, in another scheme, the main mounting plate 1 is further provided with a set of limiting components 7 matched with the limiting seat 6, to limit the maximum movement stroke of the auxiliary mounting plate 2 when it is retracted.
[0046] In the scheme, the limiting component 7 will hinder the limiting seat 6, thereby limiting the auxiliary mounting plate 2 from continuing to retract, and by reasonably designing the position and structure of the limiting component 7, it will interact with the limiting seat 6 when the auxiliary mounting plate 2 is retracted to the predetermined maximum stroke position, preventing the auxiliary mounting plate 2 from further moving, thereby realizing the accurate limitation of the maximum movement stroke of the auxiliary mounting plate 2 when it is retracted, so that the auxiliary mounting plate 2 can be extended or retracted within the set range, improving the accuracy and reliability of the equipment operation.
