Description

Technical Field

[0001] This utility model belongs to the field of cardboard conveying, specifically relating to a flip-driven pressure roller structure and a cardboard conveying device. Background Technology

[0002] Cardboard box production requires processes such as grooving and creasing on the cardboard. During the connection between various workstations, a cardboard conveying device needs to be set up to transfer the cardboard.

[0003] Existing cardboard conveying devices can refer to a cardboard conveying wheel set and carton forming machine disclosed in Chinese Patent No. CN202121641573.4. The cardboard is clamped by drive rollers and rollers so that the cardboard is conveyed by the rotation of the drive rollers. In addition, in order to ensure the effectiveness of clamping the cardboard, springs are set so that the rollers are pressed downward on the drive rollers by the elasticity of the springs.

[0004] The drawback of the aforementioned cardboard conveying device is that when paper jams occur, the cardboard clamped between the drive roller and the roller needs to be removed. However, the roller, under the action of the spring, always cooperates with the drive roller to clamp the cardboard, making it difficult to remove the cardboard. Utility Model Content

[0009] The present invention is further configured such that the transmission roller is used to transmit the cardboard that is closer to k1 in the horizontal direction to the side that is closer to k3 in the horizontal direction.

[0010] The present invention is further configured such that: the swing mounting frame is provided with a second mounting position, and the transmission pressure roller is rotatably mounted in the second mounting position; the rotation axis of the transmission pressure roller relative to the swing mounting frame is k2, wherein k1, k2, k3, and k4 are arranged in parallel and non-collinear order.

[0011] The present invention is further configured such that k1 and k3 are located at both ends of the length of the swing mounting frame, and k2 is located in the middle of the length of the swing mounting frame.

[0012] The present invention is further configured such that: the swing mounting bracket is V-shaped, the first mounting position and the third mounting position are located at both ends of the V-shape of the swing mounting bracket, and the second mounting position is located at the corner of the V-shape of the swing mounting bracket; and / or, wherein the plane where k1 and k3 are located is s1, the output shaft of the drive cylinder extends and retracts to drive the swing mounting bracket to form a downward state and a raised state, and in the downward state, k2 is located on the side facing downwards from s1.

[0013] The present invention is further configured such that: there are two swing mounting brackets, which are respectively set at both ends of the axial direction of the transmission pressure roller, and a mounting link is provided between the two swing mounting brackets for fixing the two swing mounting brackets together, and the transmission pressure roller is rotatably mounted on the outer periphery of the mounting link.

[0014] The present invention is further configured such that: the number of driving cylinders is 1, and the output shaft of the driving cylinder is hinged to one of the swing mounting frames on the side away from the transmission pressure roller; or, the number of driving cylinders is 2, and the output shaft of one driving cylinder is hinged to one of the swing mounting frames on the side away from the transmission pressure roller, and the output shaft of the other driving cylinder is hinged to the other swing mounting frame on the side away from the transmission pressure roller.

[0015] The present invention is further configured to include a pressure regulating valve, which is connected to the drive cylinder to control the downward pressure intensity of the transmission pressure roller through the pressure regulating valve.

[0016] The present invention is further configured such that: the transmission pressure roller is a sun wheel; and / or, wherein the height of k4 is higher than the height of k3.

[0017] A cardboard conveying device, characterized in that it comprises: a frame; a conveyor roller rotatably mounted on the frame; a power unit for driving the conveyor roller to rotate; a plurality of the aforementioned flip-drive type pressure roller structures, with mounting bases mounted on the frame; a drive cylinder operating to drive the conveyor rollers to flip with the swing mounting frame, causing them to face downwards towards the conveyor roller and upwards away from the conveyor roller; cardboard is input from the side of the conveyor roller closest to k1 and output from the side of the conveyor roller closest to k3 under the rolling action of the conveyor roller and the conveyor rollers.

During the transport process, the transmission pressure roller rotates synchronously to ensure the stability of the pressing. When the cardboard does not need to be clamped and transported, the driving cylinder works to drive the swing mounting frame to the lifting state, so that the transmission pressure roller lifts up with the swing mounting frame to release the pressure on the cardboard. Thus, when problems such as cardboard jamming occur, the cardboard is easier to remove. 2. In this embodiment, the cardboard is transported from back to front. Since the height of k3 is lower than the height of k1 when the cardboard is pressed down, the force acting on the transmission pressure roller during the forward transport of the cardboard generates an upward flipping force on the swing mounting frame. The force acting on the swing mounting frame by the driving cylinder is a force that drives the swing mounting frame to flip downward. The two forces are opposite in direction to prevent the transmission pressure roller from pressing the cardboard too downward and causing damage to the cardboard. Attached Figure Description

[0040] To enable those skilled in the art to better understand this utility model and to more clearly define the scope of protection claimed by this utility model, the present utility model is described in detail below with reference to certain specific embodiments. It should be noted that the following are only some specific embodiments of the present utility model, and the specific and direct descriptions of related structures are merely for the convenience of understanding the present utility model; the specific features do not necessarily or directly limit the scope of implementation of the present utility model. Conventional choices and substitutions made by those skilled in the art under the guidance of the present utility model should all be considered within the scope of protection claimed by this utility model.

[0041] Example 1:

[0042] like Figures 1-3As shown, this utility model discloses a tilting drive type pressure roller structure, including:

[0043] Mounting base 2;

[0044] The swing mounting bracket 3 is provided with a first mounting position 31, a second mounting position 32 and a third mounting position 33 arranged in sequence facing forward. The first mounting position 31 is hinged to the mounting base 2.

[0045] Transmission pressure roller 4 is rotatably mounted in the second mounting position 32; and,

[0046] Drive cylinder 5, the cylinder body of drive cylinder 5 is hinged to mounting base 2, and the output shaft of drive cylinder 5 is hinged to third mounting position 33.

[0047] The rotation axis of the swing mounting bracket 3 relative to the mounting base 2 is k1, the rotation axis of the transmission pressure roller 4 relative to the swing mounting bracket 3 is k2, the rotation axis of the output shaft of the drive cylinder 5 relative to the swing mounting bracket 3 is k3, and the rotation axis of the cylinder body of the drive cylinder 5 relative to the mounting base 2 is k4. Among them, k1, k2, k3, and k4 are not collinear and are oriented to the left and right.

[0048] The output shaft of the drive cylinder 5 extends and retracts to drive the swing mounting bracket 3 to form... Figure 3 The aforementioned downward pressure state and Figure 2 The indicated lifting state;

[0049] When in the depressed state, the height of k3 is lower than the height of k1.

[0050] Therefore, 1. When it is necessary to clamp and transport the cardboard 9, the drive cylinder 5 is used to drive the swing mounting frame 3 to the downward pressing state, so that the transmission pressure roller 4 is pressed down with the swing mounting frame 3, thus pressing the cardboard 9 above it. During the transport of the cardboard 9, the transmission pressure roller 4 rotates synchronously to ensure the stability of the pressing. When it is not necessary to clamp and transport the cardboard 9, the drive cylinder 5 is used to drive the swing mounting frame 3 to the lifting state, so that the transmission pressure roller 4 is lifted with the swing mounting frame 3, thereby releasing the pressure on the cardboard 9. When problems such as paper jams occur, paperboard 9 is easier to remove; 2. In this embodiment, paperboard 9 is transported from back to front, and since the height of k3 is lower than the height of k1 when it is pressed down, the force acting on the transmission pressure roller 4 during the forward transport of paperboard 9 generates an upward flipping force on the swing mounting frame 3, while the force acting on the swing mounting frame 3 by the drive cylinder 5 is a force that drives the swing mounting frame 3 to flip downward. The two forces are opposite in direction to prevent the transmission pressure roller 8 from pressing the paperboard 9 too downward and causing damage to the paperboard 9.

[0051] Compared to the more readily conceivable straight-up-down solution of directly fixing the drive cylinder 5 to the mounting base 2 and then rotating the transmission pressure roller 4 onto the output shaft of the drive cylinder 5, this embodiment uses a swing mounting bracket 3 to mount the transmission pressure roller 4 onto the mounting base 2. The drive cylinder 5 hinges the mounting base 2 and the swing mounting bracket 3, so that the cardboard 9 will basically not generate bending moment on the output shaft of the drive cylinder 5 during transmission, improving the smoothness of the extension and retraction of the drive cylinder 5. In contrast, the straight-up-down solution is prone to generating bending moment (easy to constrict) on the output shaft of the drive cylinder 5 during the transmission of the cardboard 9, resulting in uneven cylinder lifting and thus affecting transmission accuracy.

[0052] Preferably, k1 and k3 are located at both ends of the length of the swing mounting bracket 3, and k2 is located in the middle of the length of the swing mounting bracket 3, so that the lever arm of the drive cylinder 5 is greater than the lever arm of the transmission pressure roller 4, thereby providing a greater downward force with a smaller air supply pressure.

[0053] Specifically, the swing mounting bracket 3 is arranged in a V shape, with the first mounting position 31 and the third mounting position 33 located at both ends of the V-shape of the swing mounting bracket 3, and the second mounting position 32 located at the corner of the V-shape of the swing mounting bracket 3; wherein, the plane where k1 and k3 are located is s1, and in the pressed state, k2 is located on the lower right side of s1.

[0054] In other embodiments, the first mounting position 31, the third mounting position 33, and the second mounting position 32 may be arranged in a forward-facing manner.

[0055] Specifically, the mounting bracket includes a horizontal mounting plate 21, a vertical mounting plate 22, two first mounting side plates 23, and two second mounting side plates 24. The vertical mounting plate 22 is fixedly installed on the front side of the horizontal mounting plate 21 by welding, plugging, or other methods and extends upward. The two first mounting side plates 23 are fixedly installed on the lower rear side of the horizontal mounting plate 21 by welding, plugging, or other methods and extend downward. The two second mounting side plates 24 are fixedly installed on the upper front side of the vertical mounting plate 22 by welding, plugging, or other methods and extend forward. There are two swing mounting brackets 3. The two swing mounting brackets 3 are respectively set at the left and right ends of the transmission pressure roller 4. The two swing mounting brackets 3 are fixedly connected by a mounting rod 34 through plug-in connection so that the mounting rod 34 fixes the two swing mounting brackets 3. The transmission pressure roller 4 is rotatably mounted on the outer periphery of the mounting rod 34 by means of bearing. In addition, the first mounting position 31 of the two swing mounting brackets 3 is respectively hinged to the lower end of different first mounting side plates 23 to complete the installation.

[0056] Therefore, the combination of the two swing mounting brackets 3 and the mounting link 34 for the installation of the transmission pressure roller 4 makes the installation of the transmission pressure roller 4 more stable.

[0057] In this embodiment, there is one drive cylinder 5. The upper end of the cylinder body of the drive cylinder 5 is hinged to the right side of the second mounting side plate 24 on the right side, while the lower end of the output shaft of the drive cylinder 5 is hinged to the right side of the swing mounting bracket 3 on the right side.

[0058] In other embodiments, two drive cylinders 5 may be used. The upper end of the cylinder body of one drive cylinder 5 is hinged to the right side of the second mounting side plate 24 on the right side, and the lower end of the output shaft of the drive cylinder 5 is hinged to the right side of the swing mounting bracket 3 on the right side. The upper end of the cylinder body of the other drive cylinder 5 is hinged to the left side of the second mounting side plate 24 on the left side, and the lower end of the output shaft of the drive cylinder 5 is hinged to the left side of the swing mounting bracket 3 on the left side.

[0059] Preferably, the transmission pressure roller 4 is a sun wheel, which allows for elastic pressing of the cardboard 9 and has a higher coefficient of friction to improve transmission stability.

[0060] In the raised state, the height of k3 is also lower than the height of k1, and the angle between s1 and the horizontal plane is α1, 0°≤α1≤10°, and 5° is specifically used in this embodiment.

[0061] In the downward pressure state, the angle between s1 and the horizontal plane is α2, 10°≤α2≤30°, and this embodiment specifically uses 23°.

[0062] Example 2:

[0063] like Figure 4 As shown, this utility model also discloses a flip-driven pressure roller structure, whose main structure is the same as that of Embodiment 1. The difference is that it also includes a pressure regulating valve 6. The pressure regulating valve 6 and the driving cylinder 5 are connected to each other so as to control the downward pressure intensity of the transmission pressure roller 4 through the pressure regulating valve 6, thereby adapting to different cardboard 9 for pressing and ensuring the stability of transmission.

[0064] Preferably, in this embodiment, the regulating valve is fixedly installed on the top rear side of the vertical mounting plate 22.

[0065] Example 3:

[0066] like Figures 5-6 As shown, this utility model discloses a cardboard conveying device, comprising:

[0067] Rack 7;

[0068] The conveyor roller 8 is rotatably mounted on the frame 7. Specifically, the right end of the conveyor roller 8 is rotatably mounted on the frame 7 using a bearing seat.

[0069] The power unit 81 can be a servo motor alone or a combination of a servo motor and a reducer. The output shaft of the power unit 81 is connected to the left end of the transmission roller 8 by a coupling so that the power unit 81 can drive the transmission roller 8 to rotate.

[0070] The flip-drive pressure roller structure 1 described in multiple embodiments one or two is specifically used in this embodiment with seven rollers. The mounting base 2 is installed on the frame 7. Specifically, the horizontal mounting plate 21 and the vertical mounting plate 22 are respectively attached to the frame 7, and the mounting base 2 is fixedly installed on the frame 7 with high strength and high precision by multiple sets of bolts and nuts.

[0071] The transfer roller 4 is located above the transfer roller 8. The drive cylinder 5 works to drive the transfer roller 4 to rotate with the swing mounting frame 3, so that it moves downward toward the transfer roller 8 and upward away from the transfer roller 8. In the raised state, the transfer roller 4 and the transfer roller 8 maintain a certain distance. In the pressed state, the transfer roller 4 presses down on the transfer roller 8 so that when the cardboard 9 is transferred, the transfer roller 8 and the transfer roller 4 can clamp the cardboard 9 from top to bottom for transfer.

[0072] Therefore, the cardboard 9 to be transported is input from the rear of the transport pressure and the transport pressure roller 8 is rotated under the operation of the power unit 81. As a result, the cardboard 9 is output forward under the clamping and rolling action of the transport pressure roller 8 and the transport pressure wheel 4. When problems such as paper jam occur, the operation of the power unit 81 is stopped, and the operation of the drive cylinder 5 is used to lift the transport pressure wheel 4 upward to release the pressure on the cardboard 9, so that the cardboard 9 can be removed.

[0073] In this embodiment, since the mounting base 2 and the frame 7 are fixedly installed, the flip-drive pressure roller structures 1 are arranged in an equally spaced manner to ensure the stability of the paperboard 9 transmission.

[0074] In other embodiments, each mounting bracket can be slidably mounted on the frame 7 along the axial direction of the transmission roller 8, and driven manually or by an electric method such as screw and nut or pulley and belt.

[0075] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
