[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0028] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making any creative work shall fall within the scope of protection of the present utility model.
[0029] In some embodiments, in order to solve the problem that the text on the front side of the batch number is blurred when the product batch number is printed by the existing high-speed cartoning machine, a method is provided as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 The high-speed cartoning machine printing roller pressure balancing device shown in the figure is mainly composed of a fixed base 100, a pressure lever 200, a pressure roller wheel 300 and a compression spring 400.
[0030] The core solution is that a mounting groove 101 is provided at the bottom of the fixed base 100, and the mounting groove 101 is a long strip-shaped groove structure that passes through from left to right. The pressure lever 200 is hingedly installed in the mounting groove 101 through a hinge shaft 205 arranged at the right end of the upper middle part thereof, forming a lever structure with the hinge shaft 205 as the hinge point.
[0031] The pressure roller 300 is connected to the right end of the pressure lever 200, and the compression spring 400 is arranged at the bottom of the left end. Under the compression of the compression spring 400, the pressure roller 300 uses the lever principle to keep the front end pressure and the rear end pressure consistent, so that the clarity of the three rows of text on the box tongue is consistent, which effectively solves the problem of unclear text on the front end of the batch number when the existing high-speed cartoning machine prints the product batch number.
[0032] In some of the embodiments, Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the fixed base 100 is a convex block with a convex structure in cross section, and a long strip groove is provided at the bottom thereof to form the mounting groove 101. A bottom plate 102 for mounting the compression spring 400 is provided at the bottom of the left end of the mounting groove 101, and a U-shaped support frame 103 for mounting the hinge shaft 205 is provided at the right end.
[0033] In order to realize the installation and fixation of the device, mounting holes 104 are respectively provided at the four corners of the fixed base 100, and each mounting hole 104 is detachably mounted on the device using bolts. An adjustment screw hole 106 is provided on the top of the fixed base 100 protrusion, and pin holes 105 are respectively provided on the two inner side walls of the U-shaped support frame 103, which are used to install the adjustment bolt 500 and the hinge shaft 205 respectively.
[0034] In addition, the fixed base 100, the bottom plate 102 and the U-shaped support frame 103 are all made of stainless steel or aluminum alloy. The bottom plate 102 and the U-shaped support frame 103 are installed at both ends of the installation groove 101 in a detachable manner using screws, or are fixedly installed at both ends of the installation groove 101 using a welding connection solution.
[0035] In some of the embodiments, Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the pressure lever 200 mainly includes a first connecting rod 201 and a second connecting rod 202 which are connected as one body, and the second connecting rod 202 is fixedly arranged at the right end of the first connecting rod 201 .
[0036] A square reinforcing block 203 is provided at the connection between the first connecting rod 201 and the second connecting rod 202, and a hinge shaft 205 is provided in a through hole passing through the left and right sides of the square reinforcing block 203. The hinge shaft 205 and the pressure lever 200 are arranged in a cross shape, and the pressure lever 200 forms a lever structure through the hinge shaft 205.
[0037] Specifically, Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the cross section of the first connecting rod 201 is an outer hexagonal structure, and its top and bottom are flat, so as to facilitate the matching installation with the compression spring 400 and the adjusting bolt 500, increase the contact area between the two, and thus ensure the stability of the pressure lever 200 during the left and right flipping process. The cross section of the second connecting rod 202 is circular, so that the eccentric bearing 301 can be installed at its tail end.
[0038] In addition, in order to improve the stability of the pressure lever 200 during the left-right flipping process and prevent it from shaking left-right during the process of printing the product batch number by the high-speed cartoning machine, which affects the printing effect, the two ends of the hinge shaft 205 are sleeved with a limiting shaft sleeve 204, and the two ends of the hinge shaft 205 are respectively embedded in the pin holes 105 of the two inner side walls of the U-shaped support frame 103. The limiting shaft sleeve 204 can be rotatably sleeved on the two ends of the hinge shaft 205, and its left and right ends are respectively connected to the U-shaped reinforcement block 203 and the inner wall gap of the U-shaped support frame 103.
[0039] In some of the embodiments, Figure 1 , Figure 4 , Figure 5 and Figure 8 As shown, in order to ensure that the batch number is printed clearly and completely during the process of the high-speed cartoning machine printing the product batch number, an eccentric bearing 301 is fixedly arranged in the inner hole of the pressure roller 300, and the eccentric bearing 301 is key-connected with the right end of the second connecting rod 202. Through the arrangement of the eccentric bearing 301, the pressure roller 300 forms an eccentric rotation with the second connecting rod 202 as the center during use.
[0040] The compression spring 400 is vertically mounted in the mounting groove 101 at the left end of the fixed base 100, and its upper end is fixedly mounted in the slot 206 at the bottom of the left end of the first connecting rod 201, and its lower end is fixedly connected to the bottom plate 102 with the limit column 401 sleeved therein. The compression spring 400 is in a compressed state, and always provides an upward thrust to the left end of the first connecting rod 201, and uses the lever principle to keep the pressure at the front end of the pressure roller 300 consistent with the pressure at the rear end, so that the clarity of the three rows of text on the box tongue is consistent.
[0041] In some of the embodiments, Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the pressure balancing device further includes an adjusting bolt 500 , which is threadedly installed in the adjusting screw hole 106 at the top of the fixed base 100 , and the lower end of the adjusting bolt 500 abuts against the middle of the pressure lever 200 .
[0042] The height of the lower end of the adjusting bolt 500 can be adjusted up and down by rotating the adjusting bolt 500. The lower end of the adjusting bolt 500 contacts the pressure lever 200, which can limit the pressure lever 200 and prevent the pressure lever 200 from swinging too much up and down, thereby affecting the batch number printing effect.
[0043] like Figures 1 to 8 As shown, the high-speed cartoning machine printing roller pressure balancing device is mainly composed of a fixed base 100, a pressure lever 200, a pressure roller wheel 300 and a compression spring 400. During the packaging process of the cartoning machine, when the paper box tongue passes through the letter base, the eccentrically arranged pressure roller wheel 300 is squeezed by the compression spring 400 and uses the lever principle to keep the front end pressure and the rear end pressure of the pressure roller wheel 300 consistent, so that the clarity of the three rows of text on the box tongue is consistent, which solves the problem of unclear text on the front end side of the batch number when the existing high-speed cartoning machine prints the product batch number.
