Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0046] like Figure 1 - Figure 9 As shown, the present invention provides:

[0047] A labeling and conveying integrated labeling machine includes a cabinet 10 and a front conveying mechanism 20 mounted on the cabinet 10. A rear conveying mechanism 30 is mounted on one side of the cabinet 10 via a mounting bracket 11. A labeling mechanism 40 is mounted on one side of the upper surface of the cabinet 10. A pressing unit 50 is mounted on the middle of the upper surface of the mounting bracket 11 via a base 12.

[0048] The pressing unit 50 includes a vertical plate 51 fixed on the base 12. A receiving platform 52 is mounted on the vertical plate 51 via a mounting seat. A retainer 53 is slidably connected to the front of the vertical plate 51 via two front sliding grooves.

[0049] The pressing unit 50 further comprises a fixing seat assembled on the vertical plate 51, a threaded adjusting screw is connected on the fixing seat, one end of the adjusting screw is rotatably connected to the retainer 53 through a bearing, and the retainer 53 can be displaced up and down to adjust the position by rotating the adjusting screw.

[0050] As shown in Figure 2 , Figure 5 , Figure 6 and Figure 8 , the retainer 53 is assembled with a front moving assembly 54, the front moving assembly 54 comprises a front shaft 541 rotatably connected to the retainer 53, a through slot is formed in the back of the retainer 53 and communicated with one of the front sliding grooves, a first motor frame is slidably connected to the back of the retainer 53 through a back sliding groove, one end of the first motor frame penetrates into the through slot and is connected to the retainer 53, and the first motor frame is assembled with a first driving piece 542 connected to the front shaft 541.

[0051] As shown in Figure 1 , Figure 2 and Figure 3 , the retainer 53 is further assembled with an edge pressing assembly 55, the edge pressing assembly 55 comprises a special-shaped piece 551 fixed to the retainer 53 through an L-shaped connecting piece, the special-shaped piece 551 is slidably connected with an inclined pressing rod 552 on the lower surface, the inclined pressing rod 552 is connected with a reciprocating screw rod 554 assembled on the special-shaped piece 551 to swing forward and backward on the surface of the product after labeling.

[0052] The edge pressing assembly 55 further comprises a screw rod nut 555 mounted on the reciprocating screw rod 554, the top of the screw rod nut 555 is slidably connected to the lower surface of the special-shaped piece 551, one end of the two inclined pressing rods 552 is rotatably connected together through a pin shaft, the bottom of the screw rod nut 555 is connected to the top end of the pin shaft through a connecting column, a guide sliding groove is formed in the upper surface of the inclined pressing rod 552, a guide sliding block 556 is slidably connected in the guide sliding groove, the guide sliding block 556 is rotatably connected to the bottom of the special-shaped piece 551, and a horizontal pressing rod 553 is fixed to the two sides of the special-shaped piece 551 through connecting rods.

[0053] It is worth noting that the inclined pressing rod 552 and the horizontal pressing rod 553 are in a smooth state when they contact the surface of the product, and the friction generated during contact will not cause the product to displace, so that the inclined pressing rod 552 will not cause the product to displace when it swings forward and backward, and the setting of the horizontal pressing rod 553 makes up for the pressing gap of the inclined pressing rod 552 on the middle position of the label.

[0054] As shown in Figure 2 , Figure 5 and Figure 6As shown, the lower surface of the retainer 53 is rotatably connected with a driven bevel gear through a bearing seat, and the front shaft 541 is equipped with a driving bevel gear engaged with the driven bevel gear, and one end of the driven bevel gear and one end of the reciprocating lead screw 554 are both installed with a pulley, and the two pulleys are jointly engaged with a synchronous belt 56;

[0055] Specifically, when the front shaft 541 rotates, the driving bevel gear will drive the driven bevel gear to rotate, and then under the cooperation of the pulley and the synchronous belt 56, the reciprocating lead screw 554 is rotated, so that the lead screw nut 555 moves back and forth with the two inclined pressing rods 552, and the angle between the two inclined pressing rods 552 gradually changes during the movement to adapt to the bubbles, poor adhesion and edge lifting problems of the product surface label at different positions, and the reciprocating movement of the inclined pressing rod 552 can increase the contact time with the label, and as much as possible improve the subsequent processing effect of the label, so that the label is attached more flat and compact.

[0056] As shown in Figure 4 , Figure 6 , Figure 7 and Figure 8 , the lower surface of the retainer 53 is rotatably connected with a driven bevel gear through a bearing seat, and the front shaft 541 is equipped with a driving bevel gear engaged with the driven bevel gear, and one end of the driven bevel gear and one end of the reciprocating lead screw 554 are both installed with a pulley, and the two pulleys are jointly engaged with a synchronous belt 56;

[0057] In particular, one end of the front shaft 541 is provided with a slot matched with the linkage shaft 572, and the length of the slot is greater than the length of the linkage shaft 572, and a limiting groove is formed in the inner wall of the slot, and a limiting slide is fixed on the outer wall of the linkage shaft 572 matched with the limiting groove, so that when the linkage shaft 572 is inserted into the slot, the front shaft 541 will drive the linkage shaft 572 to rotate, and the other end of the linkage shaft 572 is installed in the bearing seat, so that the linkage shaft 572 will not affect the electric push rod 571 when rotating, and when the electric push rod 571 moves the linkage shaft 572 in the slot, it can still rotate with the front shaft 541 during the movement;

[0058] The linkage shaft 572 is equipped with a cam 573, and the outer wall of the receiving table 52 is fixed with an extension rod 574;

[0059] Specifically, when the product without label or the product treated by the edge compression assembly 55 fails, the linkage shaft 572 is pushed to move into the slot by the electric push rod 571, so that the cam 573 moves to the position corresponding to the extension rod 574. It is worth noting that the bottom end of the cam 573 should not be perpendicular to the extension rod 574 before moving, which is to ensure that the movement will not be blocked. When it moves to the position corresponding to the extension rod 574, the cam 573 will be tilted downward by the extension rod 574 during the rotation of the linkage shaft 572, so as to drive the receiving table 52 to tilt downward, so that the defective product on the surface of the receiving table 52 can slide to one side. After sliding, the linkage shaft 572 is driven by the electric push rod 571 to drive the cam 573 to reset backward, wherein it is worth noting that the base 12 surface is provided with a receiving box corresponding to the product sliding position. After the receiving table 52 is tilted, the defective product can slide into the receiving box for centralized collection.

[0060] As shown in Figure 7 , the two ends of the receiving table 52 inserted into the mounting seat are jointly sleeved with torsion springs 58, and the front surface of the vertical plate 51 is provided with a limiting piece abutting against the surface of the receiving table 52;

[0061] Specifically, after the receiving table 52 is tilted downward under the action of the cam 573, when the cam 573 is no longer abutted against the extension rod 574, the receiving table 52 will be driven to rotate upward to the state abutting against the limiting piece under the action of the torsion spring 58. In this state, it is in a horizontal state. At the same time, it is worth noting that the force applied by the front shaft rod 541 to the product to drive it to move will not drive the receiving table 52 to tilt downward.

[0062] As shown in Figure 2 , Figure 5 and Figure 4 , the compression unit 50 further comprises a rear moving assembly 59 assembled on the vertical plate 51. The rear moving assembly 59 is installed on the second motor frame on the back of the vertical plate 51. The second motor frame is fixed with a second driving piece 591. One end of the second driving piece 591 is provided with a rear shaft rod 592. Preferably, the top of the front surface of the vertical plate 51 is provided with a camera for monitoring the product after labeling. Preferably, the first driving piece 542 and the second driving piece 591 are both electric motors.

[0063] Specifically, by sleeving different thickness of thickening sleeves on the surface of the rear axle rod 592, the diameter of the rear axle rod 592 can be changed, and thus the distance between the rear axle rod 592 and the receiving table 52 can be changed to adapt to products of different thicknesses; specifically, after the product completes labeling by the labeling mechanism 40, when it is gradually moved to the surface of the receiving table 52 under the action of the front conveying mechanism 20, the product is moved towards the edge pressing assembly 55 under the action of the rotating front axle rod 541, and the label is pressed under the action of the edge pressing assembly 55; when the product is moved to contact the rear axle rod 592 under the action of the front axle rod 541, the product continues to move under the action of the rotating rear axle rod 592 in this process; when the product is not in contact with the front axle rod 541 but only in contact with the rear axle rod 592, the label attached to the surface of the product is checked by the camera; when it is found that the product is not labeled or the label still has problems after being processed by the edge pressing assembly 55, the receiving table 52 is tilted downward again by the cam 573, so that the defective product slides off the receiving table 52, and the good product normally moves backward to the rear conveying mechanism 30 under the action of the rear axle rod 592, and is conveyed to the good product receiving place by the rear conveying mechanism 30.

[0064] Specifically, the labeling and conveying integrated labeling machine works / uses as follows:

[0065] 1. Device startup and parameter presetting

[0066] Start the first driving member 542 and the second driving member 591, adjust the height of the retainer 53 by adjusting the screw rod, and match the product thickness;

[0067] 2. Product input and preliminary labeling

[0068] Place the product to be labeled on the front conveying mechanism 20, convey it to the receiving table 52, and complete the label sticking by the labeling mechanism 40;

[0069] 3. Dynamic pressing treatment

[0070] The front axle rod 541 rotates to drive the product to move towards the edge pressing assembly 55, the driving bevel gear drives the reciprocating screw rod 554 to rotate through the synchronous belt 56, drives the inclined pressing rod 552 to reciprocate and press the label, and the horizontal pressing rod 553 synchronously supplements the middle area;

[0071] 4. Quality detection and defective product determination

[0072] After pressing, the product contacts the rear axle rod 592, the camera scans the label state in real time, and if it is detected that the label is not pasted or has pressing defects, the system marks it as a defective product;

[0073] 5. Defective product automatic sorting process

[0074] The electric push rod 571 pushes the linkage shaft 572 forward, so that the cam 573 contacts the extension rod 574, the rotating cam 573 lifts the extension rod 574, and drives the receiving table 52 to tilt downward against the force of the torsion spring 58, and the defective product slides into the receiving box;

[0075] 6、Good product normal output

[0076] The qualified product is conveyed to the rear conveying mechanism 30 through the rear shaft rod 592, and finally enters the good product receiving area;

[0077] 7、Device reset and continuous operation

[0078] After the defective product is sorted, the electric push rod 571 is retracted to drive the cam 573 to reset, the receiving table 52 recovers to the horizontal state under the action of the torsion spring 58, and the next cycle is entered.

[0079] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art, according to the technical scheme and the inventive concept of the present application, within the technical range disclosed by the present application, makes equivalent replacement or change, should be covered in the protection scope of the present application.
