Description

Technical Field

[0001] The utility model particularly relates to a novel guide wheel device. Background Art

[0002] The folding cover carton sealing machine is a device that closes the upper cover of the carton and seals it on the carton mouth with tape to complete the packaging. The carton enters the folding cover carton sealing machine from one end, and the lower machine movement below completes the tape sealing at the bottom, and the folding cover mechanism and upper machine movement arranged in sequence above complete the closing of the cover and the upper tape sealing in turn.

[0003] The cover folding mechanism blocks the front cover by the front cover folding arm during the carton moving process, pushes the rear cover by the rear cover folding arm, and then flips the side cover folding plates on both sides. However, the existing cover folding and sealing machines generally provide guide wheels on both sides of the carton conveying path, and correct and shape the carton by the guide wheels. For example, a carton sealing machine disclosed in Chinese patent publication number CN115092474A discloses that by loosening the nut, the bolt slides along the arc-shaped slide groove, thereby driving the swing arm to swing, and the guide wheel is adjusted by swinging, and locked and unlocked by the locking member, so as to improve the convenience of adjustment.

[0004] However, when the guide wheel installation and adjustment method is used, the user needs to manually adjust and fix the guide wheel spacing according to the different sizes of cartons, which brings certain inconvenience to the user. Utility Model Content

[0005] In view of the defects of the above-mentioned prior art, the technical problem to be solved by the present invention is: to propose a new guide wheel device.

[0006] A novel guide wheel device comprises a frame, mounting seats are symmetrically and movably arranged on both sides of the frame, conveyor belts are respectively arranged on the two mounting seats, and the two conveyor belts are arranged opposite to each other to form a carton conveying area between the two, a driving mechanism is arranged on the frame for driving the two mounting seats to move relatively closer or farther away, a folding cover and carton sealing device that can be raised and lowered is arranged on the frame above the conveyor belt, a guide wheel assembly that can move up and down relative to the mounting seat is arranged on the mounting seat, a through hole is arranged on one side of the guide wheel assembly, a cross bar is arranged on one side of the folding cover and carton sealing device, and the cross bar cooperates and inserts into the through hole.

[0007] In one embodiment, the guide wheel assembly includes a first guide rod and a second guide rod arranged vertically at intervals, a connecting seat movably sleeved between the first guide rod and the second guide rod, and a guide wheel rotatably arranged on the connecting seat, the contour surface of the guide wheel is flush with the conveying surface of the conveyor belt, and the perforation is formed on one side of the connecting seat.

[0008] In one embodiment, there are a plurality of guide wheels, and the guide wheels are spaced apart on the connecting seat along the same axis A, and the length direction of the axis A is perpendicular to the length direction of the cross bar.

[0009] In one embodiment, a guide groove is formed through the connecting seat, the length direction of the guide groove is arranged in the same direction as the length direction of the cross bar, a fixed shaft is slidably connected in the guide groove by bolts, and the guide wheel is placed on the fixed shaft through a bearing matching sleeve.

[0010] In one embodiment, a connecting piece is connected to one end of the first guide rod adjacent to the second guide rod.

[0011] In one embodiment, the connecting seat is movably mounted on the first guide rod and the second guide rod through linear bearings.

[0012] In one embodiment, the crossbar is inserted and fitted into the through hole through a linear bearing.

[0013] In one embodiment, a bearing seat is provided at the lower side of the mounting seat, and the bearing seat is connected to the first guide rod and the second guide rod through screws passing through the mounting seat respectively.

[0014] In summary, the beneficial effects of the present invention compared with the prior art are as follows:

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0021] like Figures 1 to 4 As shown, the embodiment of the utility model preferably provides a new guide wheel device, including a frame 1, mounting seats 2 are symmetrically and movably arranged on both sides of the frame 1, conveyor belts 3 are respectively arranged on the two mounting seats 2, and the two conveyor belts 3 are arranged opposite to each other to form a carton conveying area between the two, and the frame 1 is provided with a driving mechanism for driving the two mounting seats 2 to move relatively close to or away from each other, and a folding cover and sealing device 4 that can be lifted and lowered is arranged on the frame 1 above the conveyor belt 3, and a guide wheel assembly 5 that can move up and down relative to it is arranged on the mounting seat 2, and a through hole 6 is arranged on one side of the guide wheel assembly 5, and a cross bar 7 is arranged on one side of the folding cover and sealing device 4, and the cross bar 7 is inserted into the through hole 6 in cooperation.

[0022] The cooperation between the two mounting seats and the driving mechanism to adjust the distance between the two mounting seats is a relatively mature existing technology. It is equivalent to the conveyor belt assembly disclosed in the existing patent publication number CN115092474A, in which there are two conveyor belt assemblies, which are respectively arranged under the two guide wheel assemblies and driven by a screw rod to adjust the distance between the two conveyor belt assemblies. Its structural principle will not be described in detail here.

[0023] The folding cover and box sealing device is a relatively mature prior art, which is equivalent to the structure of the combination of the lifting mechanism and the tape output mechanism disclosed in the existing patent publication number CN115092474A, and its structural principle will not be described in detail here.

[0024] Specifically, by directly fixing the guide wheel assembly on the mounting base, the guide wheel assembly can be adjusted and moved synchronously with the conveyor belt. When cartons of different sizes are placed between the two conveyor belts for transportation, the guide wheel assembly can also synchronously contact the two sides of the carton. Moreover, since the guide wheel assembly and the mounting base are installed so as to be movable up and down relative to each other, when the folding cover and sealing device is adjusted and moved up and down relative to the frame, the synchronous lifting and lowering adjustment movement of the guide wheel assembly can be achieved through the cooperation between the cross bar of the folding cover and sealing device and the perforations in the guide wheel assembly, thereby effectively avoiding the trouble of frequently manually adjusting the relative spacing width or height of the guide wheel assembly according to the different batches of cartons of different sizes in the prior art.

[0025] Further, the guide wheel assembly 5 includes a first guide rod 61 and a second guide rod 62 which are arranged vertically at intervals, a connecting seat 63 which is movably sleeved between the first guide rod 61 and the second guide rod 62, and a guide wheel 64 which is rotatably arranged on the connecting seat 63, the contour surface of the guide wheel 64 is arranged flush with the conveying surface of the conveyor belt 3, and the through hole 6 is formed on one side of the connecting seat 63. Specifically, through the guidance of the first guide rod and the second guide rod, the connecting seat can be directed to move up and down relative to the mounting seat, and the contour surface of the guide wheel is arranged flush with the conveying surface of the conveyor belt, so that when the conveyor belt contacts the side wall of the packaging box for frictional transportation, the contour surface of the guide wheel can just contact the side wall of the packaging box, thereby realizing the positioning and guiding of the upper part of the packaging box.

[0026] Furthermore, there are a plurality of guide wheels 64, and the guide wheels 64 are arranged on the connection seat 63 at intervals along the same axis A, and the length direction of the axis A is perpendicular to the length direction of the crossbar 7. Specifically, the plurality of guide wheels is used to increase the contact area with the packaging box guide.

[0027] Furthermore, a guide groove 65 is formed through the connecting seat 63, and the length direction of the guide groove 65 is arranged in the same direction as the length direction of the cross bar 7. A fixed shaft 66 is slidably connected in the guide groove 65 by bolts, and the guide wheel 64 is placed on the fixed shaft 66 by a bearing matching sleeve. Then, the guide wheel can be fine-tuned and moved by the cooperation of the guide groove, the fixed shaft and the bolts, so as to effectively avoid the problem that the guide wheel cannot completely contact the side wall of the packaging box due to processing errors.

[0028] Furthermore, a connecting piece 67 is connected to one end of the first guide rod 61 adjacent to the second guide rod 62, thereby enhancing the structural firmness of the first guide rod and the second guide rod.

[0029] Furthermore, the connecting seat 63 is movably sleeved on the first guide rod 61 and the second guide rod 62 through linear bearings, thereby enhancing the smoothness of the vertical movement of the connecting seat along the first guide rod and the second guide rod.

[0030] Furthermore, the crossbar 7 is inserted and matched in the through hole 6 through a linear bearing, thereby enhancing the smoothness of the axial movement of the connecting seat along the crossbar.

[0031] Furthermore, a bearing seat 99 is provided at the lower side of the mounting seat 2, and the bearing seat 99 is connected to the first guide rod 61 and the second guide rod 62 through screws passing through the mounting seat 2. Thus, the first guide rod and the second guide rod are connected to the bearing seat respectively, thereby enhancing the stability of the first guide rod and the second guide rod structure.

[0032] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and the description are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
