The inclined pressure plate 130 is suitable for gradually pressing the top front cover sheet 420 of the carton 400 transmitted from the swing rod 110, and making the rear cover sheet 410 keep folding. The two outward inclined rods 140 are suitable for gradually pressing the top left cover sheet 430 and the right cover sheet 440 of the carton 400 transmitted from the inclined pressure plate 130. The gluing mechanism 200 is sequentially provided with a tape lead-out clamp 210, a first movable pressure wheel 221, a rubber tapping structure 230 and a tail pressure structure 240 along the transmission direction of the carton 400. The gluing mechanism 200 0 chassis 250 is suitable for pressing the carton 400 transmitted from the outward inclined rod 140, the tape lead-out clamp 210 is suitable for the tape to pass through and be pulled out downwards, so that the front side wall of the carton 400 hits the tape, the first movable pressing wheel 221 is hinged to the chassis 250 through the first swing arm 222, and is normally suspended, the first movable pressing wheel 221 is suitable for pressing the tape on the front side wall and the top of the carton 400, the cutting knife 231 of the rubber tapping structure 230 is suitable for reciprocating with the chain 232 to cut off the tape that has been pulled to the bottom of the rubber tapping structure 230, the tail pressure structure 240 includes a lifting bar 241, a second swing arm 242 and a second movable pressing wheel 243, the second movable pressing wheel 243 is hinged to the lower end of the lifting bar 241 through the second swing arm 242, the lifting bar 241 is normally suspended and suitable for being lifted by the carton 400, and the second movable pressing wheel 243 is suitable for pressing the tape on the rear side wall of the carton 400.

[0031] It is understandable that, referring to Figures 1 to 3 The distance between the swing rod 110, the inclined pressure plate 130, the outward inclined rod 140 and the carton 400 should not be too wide to prevent the cover sheets of the carton 400 from resetting and outward when the distance is transferred. Figure 4 There is a certain distance between the tapping structure 230 and the tape lead-out clamp 210. After the tape is cut last time, a section of tape remains at the lower end of the tape lead-out clamp 210, which is convenient for the front side wall of the subsequent carton 400 to hit and stick the section of tape.

[0032] In the utility model, the tape is led out through a narrow gap in the clip-type tape lead-out member, so the tape is not easy to get out of the track. Preferably, the inner wall surface of the tape lead-out clamp 210 is provided with a plurality of protrusions to prevent the tape from firmly adhering to the inner wall of the tape lead-out clamp 210.

[0033] The operation process of the utility model is as follows: Figures 1 to 3 , the lower end of the swing rod 110 swings in the direction W shown in the figure, so that the carton 400 can pass under the swing rod 110; after entering under the swing rod 110, the lower end of the swing rod 110 returns to the swing position and presses the rear cover sheet 410 on the top of the carton 400 to complete the folding of the cover sheet 410; the carton 400 continues to move forward, and the upper end of the front cover sheet 420 on the top of the carton hits the inclined pressure plate 130, so that the front cover sheet 420 is gradually folded; the carton 400 continues to move forward, and the upper end of the front cover sheet 420 on the top of the carton hits the inclined pressure plate 130, so that the front cover sheet 420 is gradually folded; 00 continues to move, and under the guidance and pressure of the two outward-slanting diagonal rods 140, the left cover sheet 430 and the right cover sheet 440 of the carton 400 are gradually folded together and cover the folded rear cover sheet 410 and the front cover sheet 420; after all the cover sheets on the top of the carton 400 are folded together, the chassis 250 presses to keep all the cover sheets folded together; the remaining length of the tape at the lower end of the tape lead-out clamp 210 is hit by the front side wall of the carton 400, and Then, it is pressed by the first movable pressure wheel 221 of the normal pendant, so that the tape is firmly attached to the front side wall of the carton 400; the carton 400 continues to move forward, and the already attached tape on the carton 400 is pressed by the first movable pressure wheel 221 and / or the first swing arm 222, so that the tape lead-out clamp 210 stably pulls out the tape, and the pulled-out tape is attached to the top of the carton 400; after the carton 400 deviates from the tapping structure 230 for a certain length, the cutter 231 reciprocates with the chain 232 to cut the tape, and at this time a section of tape extends from the rear end of the carton 400, and the section of tape is pressed to the rear side wall of the carton by the tail pressure structure 240; specifically, the lifting bar 241 falls after detaching from the carton 400, and the carton 400 continues to move forward, and the second movable pressure wheel 243 gradually swings down to facilitate pressing the section of tape in a straightened manner from top to bottom, so that the section of tape is firmly attached to the rear side wall of the carton 400.

[0034] Compared with the prior art, the beneficial effects of the present application include: in the processes of folding, gluing, pressing, cutting glue and tail pressing of the four cover sheets on the top of the carton 400, only the two processes of folding and cutting glue of the rear cover sheet 410 require the setting of a cylinder or a motor power part, which effectively saves the setting of power parts and makes the gluing and sealing device simpler and more practical.

[0035] Better yet, the first swing arm 222 arranges multiple first movable pressure wheels 221 at intervals along the axial direction, so that each section of the tape on the front side wall of the carton 400 is pressed by the corresponding first movable pressure wheel 221, so that the tape on the front side wall of the carton 400 is more firmly adhered; and each section of the tape on the top of the carton 400 is rolled by the multiple first movable pressure wheels 221.

[0036] In some embodiments, the carton 400 on the workbench is manually pushed so that the carton 400 can be folded and glued in sequence during the pushing process.

[0037] Reference Figure 1 In some embodiments of the present invention, a conveyor belt 300 is further included. The folding mechanism 100 and the gluing mechanism 200 are both located above the conveyor belt 300. The conveyor belt 300 is suitable for conveying cartons 400, so that the cartons 400 are sequentially conveyed through the folding mechanism 100 and the gluing mechanism 200. It can be understood that the conveyor belt 300 is connected to the corresponding pulley and the transmission motor; the conveyor belt 300 and the folding mechanism 100 and the chassis 250 have a predetermined spacing, so that each cover sheet of the carton 400 is conveniently folded during the transmission.

[0038] In some embodiments, the swing pressure power member 120 is a motor, and the motor shaft is connected to the shaft of the swing rod 110. In some embodiments of the utility model, a bracket 121 is also included, and the swing pressure power member 120 is a cylinder. One end of the swing pressure power member 120 is hinged to the bracket 121, and the other end is hinged to the middle of the swing rod 110.

[0039] Reference Figures 1 to 3 In some embodiments of the present invention, a pressing wheel 111 suitable for pressing the rear cover sheet 410 is provided at the lower end of the swing rod 110 .

[0040] Reference Figure 3 and Figure 5 In some embodiments of the utility model, shallower tape strips need to be attached to the rear side wall and the front side wall of the carton 400 (i.e., shorter tape strips extending from the top to the bottom of the rear side wall and the front side wall of the carton 400), and an intermediate pressure wheel 244 is provided on the hinge shaft between the second swing arm 242 and the lifting bar 241. The intermediate pressure wheel 244 is suitable for being pushed by the carton 400 so that the lifting bar 241 is lifted by the carton 400.

[0041] In some embodiments of the present invention, a deeper tape strip needs to be attached to the rear and front side walls of the carton 400 to increase the distance between the rubber tapping structure 230 and the tape lead-out clamp 210, and the lifting strip 241 is provided with an inclined surface or an arc surface suitable for being pushed by the carton 400, so that the lifting strip 241 is lifted by the carton 400. In the present invention, there is no need to provide a huge intermediate pressing wheel 244.

[0042] Preferably, the middle pressing wheel 244, the lifting bar 241 and the second swing arm 242 are made of relatively light materials, and the tape rolling is mainly completed by the gravity of the second movable pressing wheel 243.

[0043] Reference Figures 1 to 3In some embodiments of the present invention, a tape with a larger width is selected, and the inclined pressure plate 130 includes an arc plate 131 and a rib plate 132. The arc plate 131 is suitable for pressing the front cover plate 420 of the carton 400, and the arc plate 131 is vertically connected to the rib plate 132.

[0044] Reference Figure 3 In some embodiments of the utility model, the outward diagonal rod 140 includes a seat block 141 and an outward rod 142 having one end connected to the seat block 141. The chassis 250 is provided with a plurality of mounting holes spaced apart along the left and right directions. The seat block 141 can be connected to different mounting holes to adjust the distance between the two outward diagonal rods 140 to adapt to cartons 400 of different sizes.

[0045] It is understandable that the gluing and sealing device is provided with a film installation shaft, and the tape pulled out by the tape roll on the film installation shaft runs to the tape output clamp 210; when the tape is pulled by the moving carton 400, the tape is gradually pulled out, and the tape roll and the film installation shaft rotate. In some embodiments of the utility model, it also includes a stand and a film installation shaft rotatably connected to the upper end of the stand, the lower end of the stand is connected to the chassis 250, and the stand is provided with a first pressing spring and a push plate, and the first pressing spring presses the tape roll on the film installation shaft through the push plate to prevent the tape roll from freely pulling out the tape due to rotational inertia.

[0046] In some embodiments of the present invention, the distance between the film installation shaft and the tape lead-out clamp 210 is too long, and there is too much tape between the film installation shaft and the tape lead-out clamp 210. When the tape is pulled, the amplitude is too large, which can easily cause a large noise. Preferably, the stand is hinged with a pressure rod, and the pressure rod is connected to a second pressure spring, so that the extended end of the pressure rod abuts against the tape pulled out by the film installation shaft.

[0047] The above embodiments are only used to illustrate the technical solution of the utility model but not to limit it. Any modification or equivalent substitution that does not deviate from the spirit and scope of the utility model shall be included in the scope of the technical solution of the utility model.
