Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper box processing devices, in particular to a corrugated paper box processing device provided with a limiting mechanism. Background Art

[0002] Corrugated boxes are packaging containers made from hollow corrugated cardboard through die-cutting, creasing, stapling, or gluing. During the production process, the raw material, corrugated cardboard, will inevitably develop wrinkles during transportation, resulting in an uneven surface. To facilitate subsequent processing, it needs to be flattened before undergoing die-cutting, creasing, stapling, or gluing to form a corrugated box.

[0003] The utility model with announcement number CN214983607U discloses a corrugated cardboard flattening device for processing degradable corrugated cardboard boxes. In this utility model, a movable pin slides with a long strip of through-slot. When motor two drives the rotating arm to rotate, the movable pin moves inside the through-slot, and the connecting plate drives the pressing roller to fit the cardboard through the moving block. When motor one drives the screw to rotate, the movable plate drives the pressing roller to move in the horizontal direction, which can flatten the cardboard back and forth. Compared with the traditional manual flattening method, it has a higher degree of automation, higher flattening efficiency, and reduces the labor workload of the staff.

[0004] When the above device is in use, the operation of motor 2 drives the pressing roller to fit the cardboard to ensure smooth flattening. However, the up and down movement range of the pressing roller in the above device is limited, making it difficult to apply to the flattening of corrugated cardboards of different thicknesses. Most importantly, due to the lack of buffering measures, the pressing roller will directly press on the cardboard surface under the drive of motor 2, which can easily cause the corrugated cardboard to be dented, causing the corrugated cardboard to be damaged and unable to be processed subsequently. Therefore, in response to the above problems, a corrugated cardboard processing device with a limiting mechanism is proposed. Utility Model Content

[0005] The technical problem to be solved by the present invention is to provide a corrugated cardboard processing device with a limiting mechanism, wherein the corrugated cardboard processing device drives the connecting plate to move up and down by a cylinder, thereby driving the flattening roller mechanism to move up and down, so as to flatten cardboards of different thicknesses. In particular, since the connecting plate and the flattening roller mechanism are connected by an elastically adjustable connecting member, when the thrust applied by the cylinder is large, the flattening roller mechanism can overcome the elastic force of the elastically adjustable connecting member and move upward, thereby avoiding that the cardboard is dented due to excessive pressure, and the elastic force of the elastically adjustable connecting member is adjustable, and the elastic force can be adjusted according to cardboards of different thicknesses and material strengths, so that the cardboard can be avoided from being dented while ensuring the flattening effect, so that the device as a whole has strong applicability, and solves the technical problem in the prior art that the flattening device lacks buffer measures and is prone to being dented and damaged, making it impossible to carry out subsequent processing.

[0006] The technical solution adopted by the embodiment of the present application to solve the technical problem is:

[0007] A corrugated cardboard processing device provided with a limiting mechanism includes a table with guide plates fixedly provided on both sides, a rectangular frame slidingly provided on the guide plate, a cylinder mounted on the rectangular frame, a connecting plate fixedly connected to the output shaft end of the cylinder and connected to a flattening roller mechanism via an elastically adjustable connecting piece, a magnetic limiting baffle adsorbed and fixed on the table to limit the sliding of the corrugated cardboard box, and a screw drive mechanism to drive the rectangular frame to slide along the guide plate.

[0008] Through the above-mentioned structural form, the cylinder drives the connecting plate to move up and down, and then drives the flattening roller mechanism to move up and down, so as to flatten cardboards of different thicknesses. In particular, since the connecting plate and the flattening roller mechanism are connected by an elastically adjustable connecting member, when the thrust applied by the cylinder is large, the flattening roller mechanism can overcome the elastic force of the elastically adjustable connecting member and move upward, thereby avoiding the cardboard from being dented due to excessive pressure. In addition, the elastic force of the elastically adjustable connecting member is adjustable, and the elastic force can be adjusted according to cardboards of different thicknesses and material strengths. While ensuring the flattening effect, it can also avoid the cardboard from being dented, making the overall device highly applicable.

[0009] In one possible implementation, the elastically adjustable connecting member includes a connecting slide fixedly arranged on the side of the flattening roller mechanism, wherein a sliding shaft is slidingly arranged, the top end of the sliding shaft passes through the connecting plate, and both ends of the sliding shaft are fixedly connected with anti-slip end plates.

[0011] In a possible implementation, a buffer spring is provided on the movable sleeve outside the sliding shaft, and an elastic force adjustment member sleeved outside the sliding shaft is provided on the lower end surface of the connecting plate. Both ends of the buffer spring respectively resist the elastic force adjustment member and the connecting slide.

[0012] Through the above-mentioned structural form, the buffer spring can play a buffering role. When the pressure is too large, the buffer spring provides downward pressure to reduce the pressure. In addition, the initial length of the buffer spring can be adjusted through the elastic adjustment part, thereby adjusting different initial buffering forces to meet different needs.

[0013] In one possible implementation, the elastic force adjustment member includes an adjusting screw fixedly connected to the connecting plate, on which an adjusting wheel is threadedly connected, and a pressing plate is provided on the lower side of the adjusting wheel. The two ends of the pressing plate are sleeved outside the adjusting screw, and the middle part of the pressing plate is sleeved outside the sliding shaft, and the pressing plate is in close contact with the top of the buffer spring.

[0014] Through the above structure, when the adjusting wheel is turned, it will push the pressure plate to compress the buffer spring, thereby adjusting the initial buffer force of the buffer spring. When the initial buffer force of the buffer spring needs to be reduced, just turn the adjusting wheel in the opposite direction.

[0015] In a possible implementation, a scale rod is fixedly connected to the connecting plate and has scale lines on it. A groove is provided in the middle of the adjusting wheel, in which a movable ring is rotatably provided, and an indicator ring mounted on the scale rod is fixedly connected to the movable ring.

[0016] Through the above-mentioned structural form, when the adjusting wheel is turned up and down, the indicator ring will move up and down synchronously. The user can judge the size of the current initial buffering force of the buffer spring by the change of the scale line indication corresponding to the indicator ring, which facilitates the adjustment work.

[0017] In one possible implementation, the guide plate is an inverted L-shaped plate with a guide groove formed thereon, and a sliding guide block and a sliding strap are fixedly provided on the inner wall of the rectangular frame, wherein the sliding guide block slides in the guide groove, and the sliding strap is slidably overlapped with the upper end surface of the guide plate.

[0018] With the above structure, the sliding guide block slides in the guide groove, and the sliding strap slides and overlaps on the end surface of the guide plate, thereby preventing the rectangular frame from deflecting or overturning during the sliding process.

[0019] In a possible implementation, the magnetic limiting baffle includes a magnetic bottom plate, and a baffle is detachably mounted on the magnetic bottom plate.

[0020] Through the above-mentioned structural form, the magnetic bottom plate can be used to realize the adsorption connection between the magnetic limit baffle as a whole and the table plate, and then the setting position of the magnetic limit baffle can be changed, so as to facilitate the limiting effect on the ends of cardboards of different sizes.

[0021] In a possible implementation, the screw drive mechanism includes a drive motor and a transmission slide fixedly arranged at the bottom of the rectangular frame, and the output shaft of the drive motor is fixedly connected to a transmission screw threadedly connected to the transmission slide.

[0022] With the above-mentioned structural form, when the driving motor is working, it will drive the transmission screw to transmit, and under the action of the screw transmission, the transmission slide is driven to move, thereby realizing the movement of the driving rectangular frame.

[0023] In a possible implementation, the flattening roller mechanism includes a roller frame, on which a motorized roller is mounted.

[0024] The above-mentioned structural form can realize the installation of the electric roller.

[0026] The connecting plate is driven by a pneumatic cylinder to move up and down, thereby driving the flattening roller mechanism to move up and down, so as to flatten cardboards of different thicknesses. In particular, since the connecting plate and the flattening roller mechanism are connected by an elastically adjustable connecting piece, when the thrust applied by the pneumatic cylinder is large, the flattening roller mechanism can overcome the elastic force of the elastically adjustable connecting piece and move upward, thus avoiding excessive pressure causing the cardboard to be dented.

[0027] In addition, the elastic force of the elastically adjustable connector is adjustable, and the elastic force can be adjusted according to cardboards of different thicknesses and material strengths. While ensuring the flattening effect, it can also prevent the cardboard from being dented, making the overall device highly applicable. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0037] like Figure 1 - Figure 2 As shown, the present embodiment provides a corrugated cardboard processing device with a limiting mechanism, including a table 1, with guide plates 2 fixedly provided on both sides, a rectangular frame 3 slidingly provided on the guide plate 2, a cylinder 31 installed on the rectangular frame 3, a connecting plate 4, which is fixedly connected to the output shaft end of the cylinder 31 and is connected to a flattening roller mechanism 6 via an elastically adjustable connecting member 5, a magnetic limiting baffle 7, which is adsorbed and fixed on the table 1 to limit the sliding of the corrugated cardboard box, and a screw drive mechanism 8, which is used to drive the rectangular frame 3 to slide along the guide plate 2. Through the above-mentioned structural form, the cylinder 31 drives the connecting plate 4 to move up and down. , thereby driving the flattening roller mechanism 6 to move up and down, so as to flatten cardboards of different thicknesses. In particular, since the connecting plate 4 and the flattening roller mechanism 6 are connected by the elastically adjustable connecting member 5, when the thrust applied by the cylinder 31 is large, the flattening roller mechanism 6 can overcome the elastic force of the elastically adjustable connecting member 5 and move upward, thereby avoiding the cardboard from being dented due to excessive pressure. In addition, the elastic force of the elastically adjustable connecting member 5 is adjustable, and the elastic force can be adjusted according to cardboards of different thicknesses and material strengths. While ensuring the flattening effect, it can also avoid the cardboard from being dented, making the overall device highly applicable.

[0038] like Figure 3As shown, the elastically adjustable connecting member 5 includes a connecting slide 51 fixedly arranged on the side of the flattening roller mechanism 6, wherein a sliding shaft 52 is slidingly arranged, and the top end of the sliding shaft 52 passes through the connecting plate 4, and both ends of the sliding shaft 52 are fixedly connected with anti-slip end pieces 53. Through the above-mentioned structural form, since the connecting slide 51 can slide along the sliding shaft 52, the flattening roller mechanism 6 has the characteristic of being able to slide upward, providing the necessary structural basis for its upward sliding to achieve buffering.

[0039] In addition, a buffer spring 54 is provided on the outer movable sleeve of the sliding shaft 52, and an elastic adjustment part 55 is provided on the lower end surface of the connecting plate 4 and is sleeved on the outer side of the sliding shaft 52. The two ends of the buffer spring 54 respectively resist the elastic adjustment part 55 and the connecting slide 51. Through the above-mentioned structural form, the buffer spring 54 can play a buffering role. When the pressure is too large, the buffer spring 54 provides downward pressure to reduce the pressure. In addition, the initial length of the buffer spring 54 can be adjusted by the elastic adjustment part 55, thereby adjusting different initial buffering forces to meet different needs.

The pressing plate 553 is in close contact with the top of the buffer spring 54. Through the above-mentioned structural form, when the adjusting wheel 552 is turned, it will push the pressing plate 553 to press down the compressing buffer spring 54, thereby adjusting the initial buffer force of the buffer spring 54. When it is necessary to reduce the initial buffer force of the buffer spring 54, the adjusting wheel 552 can be turned in the opposite direction.

[0041] Among them, a scale rod 555 is fixedly connected to the connecting plate 4, on which scale lines are provided. A groove is provided in the middle of the adjusting wheel 552, in which a movable ring 554 is rotatably provided. The movable ring 554 is fixedly connected to an indicator ring 556 which is sleeved on the scale rod 555. Through the above-mentioned structural form, when the adjusting wheel 552 is twisted to move up and down, the indicator ring 556 will move up and down synchronously. The user can judge the size of the current initial buffering force of the buffer spring 54 by the change of the scale line indication corresponding to the indicator ring 556, which is convenient for the adjustment work.

[0042] like Figure 5As shown, the guide plate 2 is an inverted L-shaped plate with a guide groove 21 formed thereon. A sliding guide block 32 and a sliding strap 33 are fixedly provided on the inner wall of the rectangular frame 3, wherein the sliding guide block 32 slides in the guide groove 21, and the sliding strap 33 slides and overlaps with the upper end surface of the guide plate 2. Through the above-mentioned structural form, the sliding guide block 32 can slide in the guide groove 21, and the sliding strap 33 slides and overlaps with the upper end surface of the guide plate 2, thereby preventing the rectangular frame 3 from deflecting or overturning during the sliding process.

[0043] like Figure 6 As shown, the magnetic limit baffle 7 includes a magnetic bottom plate 71, and a baffle 72 is detachably installed on the magnetic bottom plate 71. Through the above-mentioned structural form, the magnetic bottom plate 71 can be used to realize the adsorption connection between the magnetic limit baffle 7 as a whole and the table 1, and then the setting position of the magnetic limit baffle 7 can be changed, so as to facilitate the limiting effect on the ends of cardboards of different sizes.

[0044] like Figure 1-Figure 2 As shown, the screw drive mechanism 8 includes a drive motor 81 and a transmission slide 82 fixedly arranged at the bottom of the rectangular frame 3. The output shaft of the drive motor 81 is fixedly connected to a transmission screw 83 threadedly connected to the transmission slide 82. Through the above-mentioned structural form, when the drive motor 81 is working, it will drive the transmission screw 83 to transmit, and under the action of the thread transmission, the transmission slide 82 is driven to move, thereby realizing the driving of the rectangular frame 3 to move.

[0045] like Figure 3 As shown, the flattening roller mechanism 6 includes a roller frame 61, and a motorized roller 62 is mounted on the roller frame 61. The motorized roller 62 can be installed through the above-mentioned structural form.

[0046] The use principle and use process of this utility model:

[0047] The cylinder 31 drives the connecting plate 4 to move up and down, thereby driving the flattening roller mechanism 6 to move up and down, so as to flatten cardboards of different thicknesses. Since the connecting plate 4 and the flattening roller mechanism 6 are connected by an elastically adjustable connecting member 5, when the thrust applied by the cylinder 31 is large, the flattening roller mechanism 6 can overcome the elastic force of the elastically adjustable connecting member 5 and move upward, thereby avoiding excessive pressure causing the cardboard to be dented. The rectangular frame 3 is driven to move back and forth by the screw drive mechanism 8, thereby driving the flattening roller mechanism 6 to move back and forth on the cardboard, thereby flattening the cardboard.

[0048] The above-mentioned buffering effect is specifically manifested in that since the connecting slide 51 can slide along the sliding shaft 52, the flattening roller mechanism 6 has the characteristic of being able to slide upward, and the buffer spring 54 can play a buffering role. When the pressure is too large, the buffer spring 54 provides downward pressure to reduce the pressure.

[0049] In addition, the elastic force of the elastically adjustable connecting member 5 is adjustable, and the elastic force can be adjusted according to cardboards of different thicknesses and material strengths. While ensuring the flattening effect, it can also prevent the cardboard from being dented, making the overall device highly applicable. Specifically, when the adjusting wheel 552 is turned, it pushes the pressing plate 553 to press down the compression buffer spring 54, thereby adjusting the initial buffer force of the buffer spring 54. When the initial buffer force of the buffer spring 54 needs to be reduced, the adjusting wheel 552 can be turned in the opposite direction.

[0050] Finally, it should be noted that the above embodiments are merely examples for the purpose of illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to provide an exhaustive list of all possible embodiments. However, any obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
