[0022] The present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the present utility model, and detailed implementation methods and specific operation processes are given, but the protection scope of the present utility model is not limited to the following embodiments.

[0023] Refer to Figure 1 、 2 As shown in the figure, the present utility model provides a carton transfer device, including a driving system 1, a transfer device body 2 and a forming wheel system 3. The driving system 1 provides driving force for the carton transfer device and includes a motor and a gear set; the transfer device body 2 includes a transmission component 21, and the transmission component 21 is also provided with gears. The transmission component 21 is connected to the driving system 1 through gear meshing. When the driving force is transmitted from the driving system 1, it drives the transmission component 21 to perform corresponding movements.

[0024] The transmission component 21 further includes a cam 211, a driving shaft 212, a driving rocker arm 213 and an intermediate shaft 215. The cam 211 is key-connected to the driving shaft 212, and the gear is fixedly sleeved on the driving shaft 212. When the driving force is transmitted from the driving system 1, it drives the driving shaft 212 to rotate, so the cam 211 will also rotate with the driving force. The outer edge of the cam 211 abuts against the roller on the driving rocker arm 213, and the roller on the driving rocker arm 213 moves along the track on the outer edge of the cam 211. One end of the intermediate shaft 215 is fixedly sleeved into the driving rocker arm 213, and the intermediate shaft 215 is used to support the driving rocker arm 213. The driving rocker arm 213 swings around the axis of the intermediate shaft 215.

[0025] The transmission component 21 is also provided with a cylinder 214. The bottom end of the cylinder 214 is fixedly connected to the driving rocker arm 213 and is installed near the roller of the driving rocker arm 213. After the cylinder 214 is ventilated, it can hold up the driving rocker arm 213. The purpose is to always keep the roller of the driving rocker arm 213 in contact with the outer edge of the cam 211, so as to ensure that the roller of the driving rocker arm 213 moves strictly along the track of the cam 211.

[0026] Refer to Figure 2 、 3As shown, the transfer device body 2 includes a driven assembly 22 and a pushing assembly 23;

[0027] The driven assembly 22 includes a driving link 221, a driven rocker arm 222, a driven shaft 223 and a fixing bracket 238. The driving link 221 is connected to one end of the driving rocker arm 213 away from the cam 211 through a spherical plain bearing. One end of the driving link 221 away from the driving rocker arm 213 is connected to the driven rocker arm 222 through a spherical plain bearing. One end of the driven shaft 223 is fixedly sleeved on one side of the driven rocker arm 222 away from the driving link 221. The driven rocker arm 222 is key-connected to the driven shaft 223. The driven shaft 223 is sleeved in the bearing block 224, and the position of the bearing block 224 is fixed. Therefore, the power at the end of the driving rocker arm 213 can be transmitted to the driven rocker arm 222, so the driven shaft 223 will rotate with the swing of the driven rocker arm 222.

[0028] There are multiple pushing assemblies 23, and the pushing assemblies 23 are evenly spaced, as Figure 3 shown. Each pushing assembly 23 has a main link 231 and a secondary link 232. One end of the main link 231 is sleeved on the driven shaft 223 and swings with the rotation of the driven shaft 223. One end of the secondary link 232 is connected to the fixing bracket 238 through a spherical plain bearing. The installation positions of the main link 231 and the secondary link 232 are in the same plane in their movement direction; the gap between adjacent pushing assemblies 23 corresponds to the position of the sleeve grid 31 of the forming wheel system 3, and the distance of the gap corresponds to the size of the paper box. Through the driving force of the driving system 1, each component of the transfer device body 2 is driven to move, and finally the paper box is pushed out of the forming rod and into the sleeve grid 31 to complete the paper box transfer work.

[0029] Specifically, referring to Figure 4 shown, the pushing assembly 23 further includes a mounting seat 233,

[0030] One end of the main link 231 away from the driven shaft 223 is connected to the mounting seat 233 through a movable shaft 234. One end of the secondary link 232 away from the fixing bracket 238 is provided with a spherical plain bearing, and the spherical plain bearing is connected to the mounting seat 233 through a movable shaft 234. The two movable shafts 234 of the mounting seat 233 are parallel to each other, and the mounting seat 233 swings along with the movement trajectories of the main link 231 and the secondary link 232;

[0031] In this way, the secondary link 232, the main link 231 and the mounting seat 233 form a double-rocker mechanism;

[0032] The pushing component 23 further includes a spring shaft 235, a push block mounting seat 236, and a push block 237. The top of the push block mounting seat 236 is tightened to the bottom of the mounting seat 233 by screws. A plurality of symmetrically positioned spring shafts 235 are provided between two push block mounting seats 236 mounted on the same mounting seat 233. The number of spring shafts 235 can be 2 pairs. The push block 237 is mounted on the side of the push block mounting seat 236 away from the spring shaft 235. A spring is inserted into the spring shaft 235 and connected to the push block 237. At the same time, the spring shaft 235 is clamped by the push block mounting seat 236. The side of the push block 237 away from the push block mounting seat 236 directly contacts the forming rod. In this way, it can ensure that the force exerted by the push block 237 on the forming rod remains within a certain range, so that the paper box can be fixedly clamped between the spaced push blocks 237, and it can ensure that the paper box can be smoothly pushed into the sleeve grid 31 under the clamping force of the push block 237;

[0033] In this way, the spring shaft 235, the push block mounting seat 236, and the push block 237 form a clamping mechanism;

[0034] After the forming rod is docked with both ends of the clamping mechanism, the push block 237 in contact with the paper box of the clamping mechanism starts to move, and pushes the paper box outwards parallel to the direction of the forming rod. After reaching the position, the push block 237 returns to the starting position of movement, and the forming rod rotates to transfer the paper box at the next station to the appropriate position, and so on.

[0035] Specifically, referring to Figure 5 as shown, its operation method is:

[0036] When the forming rod and the sleeve grid 31 of the forming wheel system 3 reach the specified position, the paper box needs to be moved from the forming rod to the sleeve grid 31. The drive system 1 drives the cam 211. When the cam 211 moves along the return stroke trajectory, its movement trajectory passes through the drive rocker 213, the drive link 221, the follower rocker 222, the driven shaft 223, etc., so that the main link 231 moves along the Figure 5 as shown by the arrow direction, and the double-rocker mechanism makes the push block 237 move along the forming rod along the Figure 5 as shown by the arrow direction; the side of the push block 237 contacts the paper box, and finally pushes the paper box out of the forming rod and into the sleeve grid 31; when the cam moves along the push stroke trajectory, it makes the push block 237 return to its original position. When the forming wheel rotates to the next station, the paper box transfer device repeats the movement;

[0037] Its working principle and beneficial effects are:

[0038] Before entering the step of pushing the package, the paper box becomes a semi-finished product with the bottom sealed through a series of actions in the bottom forming section. It rotates the end of the forming rod to a suitable position for paper box transfer; the cam of the driving transmission component 21 makes the transmission component 21 move along a predetermined trajectory regularly; the chain end of the forming wheel system 3 also moves the sleeve grid 31 to a suitable working position, so that the semi-formed paper box can enter the inside of the sleeve grid safely and unobstructed under the push of the pushing component 23; after the two ends are docked, the push block 237 in contact with the paper box of the pushing device starts to move, and pushes the paper box outwards parallel to the direction of the forming rod. After reaching the position, the push block 237 returns to the starting position of movement, rotates the paper box in the next working position to a suitable position, and so on; in this way, the technical effect of finally and safely pushing the paper box located on the forming rod of the forming wheel into the next working position is realized. The paper box transfer device is a pure mechanical structure, with little influence of actions by external factors, a short maintenance cycle, low cost, a simple mechanism, and is stable and reliable.
