Description

[0001] Technical field.

[0002] This utility model relates to the field of cardboard box production technology, and in particular to a paper feeding component of a cardboard box printing machine.

[0003] Background technology.

[0004] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. Cardboard boxes commonly have three or five layers, while seven-layer boxes are less common. Each layer consists of linerboard, corrugated paper, core paper, and face paper. Linerboard and face paper can be made of kraft paper or kraft paper, while the core paper is made of corrugated paper. The colors and textures of each type of paper are different.

[0005] In cardboard box production, printing presses are used to print patterns and designs on the surface of the boxes for decoration or labeling purposes. During printing, paper feeding components are used to feed the cardboard sheets one by one onto the printing press. Most current paper feeding components use vacuum suction cups to pick up the cardboard sheets, and then use robotic arms or similar moving devices to deliver the cardboard sheets to the printing press. However, the suction conditions of vacuum suction cups have significant limitations, especially for uneven cardboard sheet surfaces and the characteristics of the paper. The vacuum level of the vacuum suction cups needs to be repeatedly adjusted, which is too cumbersome to operate and makes it difficult to ensure stability during the paper feeding process.

[0006] Utility model content.

[0007] The purpose of this utility model is to address the aforementioned shortcomings in the existing technology by proposing a paper feeding component for a carton printing machine.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a paper feeding component for a carton printing machine is designed, including two parallel crossbeams, with drive rollers provided at the ends between the two crossbeams, the ends of the drive rollers being rotatably connected to the crossbeams, and a first drive motor being installed on one end of one of the drive rollers, the first drive motor being fixed on the crossbeam.

[0009] A conveyor belt is installed on the drive roller, and several spaced limit strips are installed on the outer side of the conveyor belt. The limit strips are set parallel to the drive roller.

[0010] A baffle is installed above the two crossbeams. The baffle is perpendicular to the top surface of the conveyor belt and is located at the end of the conveyor belt. On both sides of the baffle, there are lifting frames that drive the baffle to rise and fall. The lifting frames are fixed on the crossbeams.

[0011] Preferably, the two lifting frames include a support base, which is vertically fixed to the end of the crossbeam. A strip groove is provided on the support base, which extends through the side of the support base. A lead screw is provided in the strip groove, the end of which is rotatably connected to the end of the strip groove. A second drive motor is installed on the top of the lead screw and fixed to the top of the support base.

[0012] A movable seat is connected to the lead screw via a nut thread, and the movable seat is connected to the baffle via a connecting bracket.

[0013] Preferably, the sides of the movable seat are all smooth surfaces and are clearance-fitted with the inner wall of the strip groove.

[0014] Preferably, a number of spaced support rollers are provided between the two drive rollers, the support rollers are placed inside the conveyor belt, and the ends of the support rollers are rotatably connected to the crossbeam.

[0015] Preferably, limiting plates are provided on both sides above the conveyor belt, the limiting plates are perpendicular to the top surface of the conveyor belt, and the bottom of the limiting plates is clearance-fitted with the top surface of the conveyor belt. Fixing frames are installed on the side of the two limiting plates that are relatively far apart, and the fixing frames are fixed on the crossbeam.

[0016] Preferably, an inclined feeding plate is provided above one end of the conveyor belt near the baffle. The feeding plate is fixed to the crossbeam by a bracket, and the top of the feeding plate is clearance-fitted with the top end of the conveyor belt.

[0017] Preferably, a support frame is installed at the lower end of the crossbeam.

[0018] The design scheme proposed in this utility model has the following beneficial effects in application:

[0019] 1. The paper feeding component of this carton printing machine, driven by the conveyor belt, allows the stacked carton boards on the conveyor belt to move towards the baffle. Under the limit of the baffle and the push of the limit strip, the bottom carton board is pushed out from the gap between the baffle and the conveyor belt, realizing the operation of feeding paper one by one. The remaining carton boards will fall between the two limit strips behind and wait for the conveyor belt to continue pushing, ensuring the stability of the entire paper feeding process.

[0020] 2. The paper feeding component of this carton printing machine can adjust the distance between the bottom of the baffle and the conveyor belt by moving the baffle up and down, so as to adapt to carton boards of different thicknesses and ensure that the carton boards can be fed out stably one by one.

[0027] Detailed implementation method.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Reference Figures 1-4 A paper feeding component for a carton printing machine includes two parallel crossbeams 1, with a support frame 16 installed at the lower end of each crossbeam 1 to support the crossbeams 1.

[0030] Drive rollers 2 are provided at the ends between the two crossbeams 1. The ends of the drive rollers 2 are rotatably connected to the crossbeams 1. A first drive motor 4 is installed on one end of one of the drive rollers 2. The first drive motor 4 is fixed on the crossbeam 1 and provides power for the rotation of the drive roller 2. A conveyor belt 3 is installed on the drive roller 2 so that the conveyor belt 3 can transmit power when the drive roller 2 rotates. In use, the stacked cardboard can be placed on the conveyor belt 3 and then the conveyor belt 3 can drive the cardboard forward. Several spaced limit strips 5 are installed on the outer side of the conveyor belt 3. The limit strips 5 are set parallel to the drive roller 2. In actual use, the height of the limit strips 5 is less than the thickness of the cardboard. When placing the cardboard, the cardboard is placed between two adjacent limit strips 5.

[0031] In order to ensure the support effect of the conveyor belt 3 on the carton board, several support rollers 12 are arranged at intervals between the two drive rollers 2. The support rollers 12 are placed inside the conveyor belt 3, and the ends of the support rollers 12 are rotatably connected to the crossbeam 1, so that the support rollers 12 can provide support for the conveyor belt 3 located between the two drive rollers 2, ensuring that the conveyor belt 3 has good force support capacity.

[0032] As the conveyor belt 3 transports the cardboard boxes, a baffle 6 is installed above the two crossbeams 1. The baffle 6 is perpendicular to the top surface of the conveyor belt 3 and is located at the end of the conveyor belt 3. On both sides of the baffle 6, there are lifting frames that drive the baffle 6 to rise and fall. The lifting frames are fixed on the crossbeams 1, so that the cardboard boxes being transported are blocked by the baffle 6. Because the baffle 6 leaves a gap between itself and the conveyor belt 3 under the action of the lifting frames, a cardboard box can pass through. The bottom cardboard box will be sent out through the gap between the baffle 6 and the conveyor belt 3. During this process, the limiting bar 5 will also push the bottom cardboard box to ensure that the cardboard box can be pushed stably. The remaining cardboard boxes will fall onto the conveyor belt 3 behind it under the obstruction of the baffle 6 until the bottom cardboard box is completely sent out. Then, the remaining cardboard boxes will continue to repeat the above operation under the drive of the conveyor belt 3 to send the cardboard boxes one by one to the printing machine.

[0033] In order to ensure that the cardboard is transported stably on the conveyor belt 3 and does not fall off the side of the conveyor belt 3, limiting plates 14 are provided on both sides above the conveyor belt 3. The limiting plates 14 are perpendicular to the top surface of the conveyor belt 3, and the bottom of the limiting plates 14 is fitted with the top surface of the conveyor belt 3 with a clearance. Fixing brackets 15 are installed on the side of the two limiting plates 14 that are relatively far apart, and the fixing brackets 15 are fixed on the crossbeam 1.

[0034] Specifically, in actual use, the limiting strip 5 can be glued to the conveyor belt 3 with strong adhesive or other glues, and the spacing between two adjacent limiting strips 5 can be controlled at a value corresponding to the length of the carton board, so as to ensure that each limiting strip 5 can provide sufficient pushing force to the carton board.

[0035] It should be noted that the two lifting frames include a support base 7, which is vertically fixed to the end of the crossbeam 1. A strip groove 8 is provided on the support base 7, which runs through the side of the support base 7. A lead screw 9 is provided in the strip groove 8, and the end of the lead screw 9 is rotatably connected to the end of the strip groove 8. A second drive motor 10 is installed on the top of the lead screw 9 and is fixed on the top of the support base 7. A movable seat 11 is connected to the lead screw 9 by a threaded nut. The movable seat 11 is connected to the baffle 6 through a connecting frame. The rotation of the lead screw 9 provides power for the lifting and lowering of the baffle 6, so that the position of the baffle 6 above the conveyor belt 3 is adjustable, so as to adjust the distance between the baffle 6 and the conveyor belt 3 according to the thickness of the carton board.

[0036] Furthermore, the sides of the movable seat 11 are all smooth surfaces and are in clearance fit with the inner wall of the strip groove 8, so that the movable seat 11 is blocked by the inner wall of the strip groove 8 when the lead screw 9 rotates, and will not rotate with the lead screw 9, ensuring that the movable seat 11 only moves in a straight line along the axis of the lead screw 9.

[0037] Finally, an inclined feeding plate 13 is provided above one end of the conveyor belt 3 near the baffle 6. The feeding plate 13 is fixed to the crossbeam 1 by a bracket, and the top of the feeding plate 13 is in clearance fit with the top end of the conveyor belt 3. In actual use, the bottom of the feeding plate 13 corresponds to the operating table of the printing machine, so that the cardboard that is sent out can fall onto the printing machine along the inclined feeding plate 13.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
