A rotating cylinder is threadedly connected to the outer edge of the threaded rod. A push plate is fixedly connected to the side of the rotating cylinder. A telescopic rod is fixedly connected between the support frame and the rotating cylinder.

[0004] However, it still has the following drawbacks in actual use:

[0005] 1. When the above-mentioned feeding and guiding device for carton printing is in use, the fixed block is pushed down by an electric telescopic rod to press the carton. However, this method is not convenient for printing assembled cartons. For flat unassembled cartons, the width of the fixed block cannot be adjusted accordingly according to the width of the carton, and the carton will bend at the crease after being stressed at the front and rear ends, thus affecting subsequent feeding.

[0006] 2. When the above-mentioned feeding and guiding device for carton printing is in use, the carton is limited by the push plate. However, after the front and rear push plates come into contact with the carton, the friction between the two will affect the feeding efficiency of the carton. Therefore, we provide a feeding and guiding device for carton printing to solve the above problems. Content of the Utility Model

Detailed implementation mode

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] Embodiment 1

[0032] Please refer to Figures 1 to 4 , the present invention is a feeding guiding device for carton printing, including a guide frame 1 and support plates 102 installed at the front and rear ends of its upper surface. The central positions of the tops of adjacent front and rear support plates 102 are fixedly connected with a U-shaped frame 104. Baffles 2 are installed between adjacent front and rear support plates 102. The inner side wall of the baffle 2 is provided with a first installation groove 201, and a first roller 202 is rotatably connected at equal intervals along the horizontal direction inside the first installation groove 201.

[0033] Specifically, conveyor rollers 101a are rotatably connected at equal intervals along the horizontal direction inside the guide frame 1. A conveyor belt 101 is sleeved on the outer wall of the conveyor roller 101a. Auxiliary rods 102a are installed on both sides of the inner wall of the support plate 102, and the other ends of the auxiliary rods 102a are installed on the outer wall of the baffle 2. A first motor 103 is installed in the middle of the outer wall of the support plate 102. The output shaft of the first motor 103 is connected to a first threaded rod 103a through a coupling. The other end of the first threaded rod 103a penetrates through the bearing on the support plate 102 and is spirally connected to the threaded groove inside the telescopic cylinder 102b. The other end of the telescopic cylinder 102b is installed in the middle of the outer wall of the baffle 2. An electric push rod 104a is installed at the central position of the top of the U-shaped frame 104. The telescopic end of the electric push rod 104a penetrates through the central position of the bottom of the U-shaped frame 104 and is connected to the central position of the upper surface of the lifting plate 104b.

[0034] Further, the first rotating roller 202 can assist the movement of the cardboard box, improving the smoothness during the movement of the cardboard box. The conveying roller 101a and the conveyor belt are both prior arts, so no further elaboration will be made here. The auxiliary rod 102a plays a role in limiting and guiding the baffle 2. Since the external thread on the outer wall of the first threaded rod 103a is helically connected to the thread groove in the telescopic cylinder 102b, the telescopic cylinder 102b will move when the first threaded rod 103a rotates. The electric push rod 104a can drive the lifting plate 104b to move up and down.

[0035] The operation process of this embodiment is as follows: Place the cardboard box to be printed on the surface of the conveyor belt 101. Then, start the first motors 103 at the front and back first. The output shaft of the first motor 103 rotates and drives the first threaded rod 103a to rotate through a coupling. The external thread on the outer wall of the first threaded rod 103a is helically connected to the thread groove in the telescopic cylinder 102b. At the same time, the baffle 2 is limited and guided by the auxiliary rods 102a on both sides. Therefore, when the first threaded rod 103a rotates, it will drive the baffle 2 to move inward or outward under the action of the thread, causing the baffles 2 at the front and back to approach the front and back ends of the cardboard box and play a limiting role. Then, when the conveying roller 101a drives the cardboard box on the conveyor belt 101 to be transported, it can play a role in limiting and guiding the transportation under the auxiliary action of the first rotating roller 202 inside the baffle 2, avoiding obstacles to the cardboard box during transportation and affecting the transportation efficiency.

[0036] Embodiment 2

[0037] Please refer to Figure 4 and Figure 5 Based on Embodiment 1, the difference from the first embodiment is that an adjusting assembly 3 is provided. The adjusting assembly 3 includes a second motor 301 and a driving wheel 301a installed on its output shaft. A driven wheel 302a is arranged on one side of the driving wheel 301a, and the rack on the outer wall of the driving wheel 301a meshes with the rack on the outer wall of the driven wheel 302a, solving the problem that the existing feeding guiding device for cardboard box printing limits the cardboard box through a push plate, and the friction between the two will affect the feeding efficiency of the cardboard box after the front and rear push plates contact the cardboard box.

[0038] Specifically, a second threaded rod 302 is installed at the central position inside the driven wheel 302a. The front and rear ends of the second threaded rod 302 respectively penetrate through the bearings at the front and rear ends of the lifting plate 104b and are helically connected to the thread grooves on the front adjusting plate 303 and the rear adjusting plate 304. Second installation grooves 303a are provided on both sides of the bottom of the front adjusting plate 303 and the rear adjusting plate 304. Second rotating rollers 305 are rotatably connected at equal intervals along the horizontal direction inside the second installation grooves 303a. Telescopic rods 306 are installed on both sides of the top of the front adjusting plate 303 and the rear adjusting plate 304.

[0039] Further, since the racks on the outer wall of the driving wheel 301a mesh with the racks on the outer wall of the driven wheel 302a, when the driving wheel 301a rotates, it will drive the driven wheel 302a and the second threaded rod 302 inside it to rotate synchronously. The external threads on the outer wall of the second threaded rod 302 are helically connected to the threaded grooves on the front adjusting plate 303 and the rear adjusting plate 304. Therefore, when the second threaded rod 302 rotates, it will drive the front adjusting plate 303 and the rear adjusting plate 304 to move in opposite or the same directions. The telescopic rod 306 plays a role in limiting and guiding the front adjusting plate 303 and the rear adjusting plate 304.

[0040] The operation process of this embodiment is as follows: After the positions of the front and rear baffles 2 are adjusted, start the second motor 301. The output shaft of the second motor 301 rotates to drive the driving wheel 301a to rotate. Since the racks on the outer wall of the driving wheel 301a mesh with the racks on the outer wall of the driven wheel 302a, when the driving wheel 301a rotates, it will drive the driven wheel 302a to rotate. When the driven wheel 302a rotates, it will drive the second threaded rod 302 inside it to rotate. Among them, the external threads on the outer wall of the second threaded rod 302 are helically engaged with the threaded grooves on the front adjusting plate 303 and the rear adjusting plate 304. And the front adjusting plate 303 and the rear adjusting plate 304 are limited and assisted in guiding by the telescopic rods 306 on both sides. Therefore, when the second threaded rod 302 rotates, it will drive the front adjusting plate 303 and the rear adjusting plate 304 to move forward or backward, so as to adjust the pressing position according to the width of the carton, avoiding the carton from bending at the crease when being squeezed by the front and rear baffles 2, which affects the subsequent feeding operation. Then start the electric push rod 104a to push the lifting plate 104b downward, so that the second roller 305 presses on the top of the carton and continuous feeding can be carried out.
