The two transmission components each include a support rod 5, a rack 6 and a slide rod 7. The two support rods 5 are symmetrically arranged on the two sides of the upper side of the pressure plate 2, and the two slide rods 7 are slidably connected to the frame 1 up and down. The two racks 6 are symmetrically arranged and respectively mesh with the two gears 41 symmetrically arranged. The distances between the two support rods 5 and the first push rod 3 are equal. It is preferred that the two support rods 5 are arranged at the midpoint from the first push rod 3 to the two ends of the pressure plate 2. The two support rods 5 are both slidably connected to the frame 1 up and down, and the two racks 6 are also arranged in a vertical row, and the length of the rack 6 corresponds to the distance of the up and down movement of the pressure plate 2. The frame 1 is provided with bearings for connecting the transmission rod 4 at positions corresponding to the two ends of the transmission rod 4. The two ends of the transmission rod 4 protrude from the bearings, and the protruding parts are provided with gears 41 and connected to the rack 6.

[0023] The utility model discloses a balanced transmission structure of a carton edge pressing machine, in which a first pushing rod 3 pushes the edge pressing plate 2 to slide up and down on the frame 1, thereby pressing the cardboard passing under the frame 1, and two supporting rods 5 are respectively connected to the left and right sides of the edge pressing plate 2, and two symmetrically arranged supporting rods 5 replace the first pushing rod and are fixedly connected to the two sides of the edge pressing plate 2, so that the point of downward pressure is evenly divided from the first pushing rod 3 to the two supporting rods 5, and the two supporting rods 5 are jointly connected by the connected transmission rod 4, so that the two sides of the edge pressing plate 2 are kept balanced and pressed downward synchronously, ensuring the balance of the downward pressure of the edge pressing plate 2, ensuring that the cardboard is evenly stressed, and maintaining the consistency of the indentation.

[0024] In this embodiment, the bottom of the first push rod 3 is hinged with a connecting seat 201, and is connected to the middle part of the edge pressing plate 2 through the connecting seat 201, that is, the first push rod 3 only pushes the edge pressing plate 2 up and down, and the transmission balance of the edge pressing plate 2 is replaced by the two support rods 5, which can better ensure the smoothness of the downward pressing process of the edge pressing plate 2.

[0025] In this embodiment, the support rod 5, the rack 6 and the first push rod 3 are all located above the working surface and perpendicular to the working surface, and the edge plate 2 and the transmission rod 4 are parallel to the working surface. Figure 5 As shown, the support rod 5 , the rack 6 and the first push rod 3 are all perpendicular to the transmission rod 4 and the edge holding plate 2 .

[0026] In this embodiment, a fixing seat 11 for the slide bar 7 to slide up and down is installed on the frame 1, and the fixing seat 11 is provided with a slider, and the slider has a sliding groove for cooperating with the slide bar 7. The slide bar 7 and the fixing seat 11 structure are mainly provided to ensure the linear sliding of the edge pressing plate 2 and prevent the transmission component from being separated from the frame 1. The rack 6 and the slide bar 7 are fixedly connected to the support rod 5. The rack 6 is provided on the side of the two support rods 5 facing each other, and the slide bar 7 is provided on the back of the support rod 5; the fixing seat 11 is adjustably connected to the frame 1, and the fixing seat 11 is provided with a strip hole 111, and the strip hole 111 is arranged horizontally The frame 1 is provided with a connecting hole 110 corresponding to the strip hole 111, that is, parallel to the transmission rod 4. The connecting hole 110 and the strip hole 111 are set at the same height. The installation of the fixing seat 11 is achieved by passing a connecting piece such as a screw through the strip hole 111 and the connecting hole 110. Before the screws are tightened, the fixing seat 11 can slide horizontally on the frame 1 to adjust the horizontal position of the fixing seat 11 on the frame 1. After the adjustment is completed, tighten the screws. This adjustment function can make the rack 6 on the support rod 5 and the gear 41 at the end of the transmission rod 4 better match, which can make up for the errors and other problems that occur during the production of the transmission component.

[0027] In this embodiment, the rack 6 and the gear 41 are both provided with mutually meshing helical teeth 60. By adopting the helical tooth 60 structure on the rack 6 and the gear 41, the transmission of the rack 6 and the gear 41 is smoother and the transmission stability is improved. The helical teeth 60 of the rack 6 are provided on the front side, and the gear 41 is located on the front side of the rack 6 and meshed with it.

[0028] In this embodiment, the frame 1 is provided with a second push rod 32, and the bottom of the second push rod 32 is connected to a fixed plate 80 for fixing the cardboard. The second push rod 32 is perpendicular to the fixed plate 80, and the fixed plate 80 is parallel to the edge pressing plate 2. The fixed plate 80 can be used to fix the cardboard to prevent the cardboard from moving during the edge pressing process, and is suitable for automated edge pressing processing. The working surface is connected to the feed surface. After the feed surface transports the cardboard to the working surface, the fixed plate 80 is used to press the fixed cardboard, and then the edge pressing plate 2 is used to press the edge of the cardboard. After the edge pressing is completed, the fixed plate 80 is released, and the cardboard is sent out through the feed surface. The first push rod 3 and the second push rod 32 can adopt general hydraulic rods or pneumatic rods and other devices.

[0029] In this embodiment, the frame 1 is arranged with at least two workstations 100 in the direction of cardboard in and out, and each of the workstations 100 is provided with a pressure plate 2, a first push rod 3 and a transmission assembly, such as Figure 1 As shown, there are two workstations 100 on the frame 1, and both workstations 100 are provided with mounting beams. The edge pressing plate 2, the first push rod 3 and the transmission assembly are all arranged on the mounting beam. The first push rod 3 is fixed to the side of the mounting beam away from each other, and the two support rods 5 are slidably installed on this side through the fixed seat 11. The transmission rod 4 is also arranged on this side through a bearing. The second push rod 32 is installed on the other side. Two sliding seats are also provided on this side. The two sliding seats are slidably connected with sliding rods 88. The bottoms of the two sliding rods 88 are respectively connected to the two sides of the upper side of the fixed plate 80. The sliding seats and the sliding rods 88 are mainly to ensure the linear sliding of the fixed plate 80 to realize double edge pressing workstations 100. The double workstations 100 can press the edges synchronously, or the single workstation 100 can press the edges alone.

[0030] Combined with the overall description of the edge pressing machine, the cardboard is transported to the working surface through the feeding surface, and the cardboard passes through the first workstation 100 and continues to move to the next workstation 100. At this time, the two sides of the cardboard are just under the two workstations 100. The second push rod 32 moves down the fixed plate 80 to fix the cardboard on the working surface, and then drives the first push rod 3, and the movable end drives the edge pressing plate 2 to move down. The two support rods 5 on the edge pressing plate 2 move down synchronously under the meshing transmission of the rack 6 and the gear 41. Since the rack 6 and the gear 41 are symmetrically arranged, the downward movement of the two support rods 5 is synchronized, ensuring that the edge pressing plate 2 is in a horizontal state and pressed, thereby ensuring the consistency of the indentation depth of the cardboard.

[0031] The above embodiments are preferred embodiments of the present invention. All structures similar to those of the present invention and equivalent changes made thereto should fall within the scope of protection of the present invention.
