Description

TECHNICAL FIELD

[0001] The utility model belongs to paper box processing technical field, more specifically, the utility model relates to a corrugated paper pasting box machine transmission device. BACKGROUND

[0002] The pasting box machine is a machine for folding and sticking the printed and die-cut paperboard, and the application of the pasting box machine is the last process of the packaging box processing in the packaging and printing industry. At present, the paper box folding processing usually needs to be completed through multiple automatic equipment and multiple processes. Since the processing speed of the pasting box machine is extremely fast in the previous process, the paper boxes of the corrugated paper are prone to be unevenly stacked or even misaligned, thereby causing the paper boxes processed by the next process equipment to have poor quality. If the speed of the conveying belt of the next process is simply reduced, the speed difference between the high-speed output of the previous process and the conveying belt of the next process after speed reduction will be caused, and the paper boxes are prone to be impacted and accumulated at the joint. The buffer assembly in the transmission device of the existing pasting box machine usually adopts a small number of rollers, which cannot effectively buffer the transmission speed of the paperboard. Moreover, since the thickness of the corrugated paper is different, the existing rollers usually have a fixed height and are only adjusted in height by a spring, and if the thickness of the paperboard increases, the height adjustment of the roller spring is insufficient to release sufficient expansion space, resulting in the accumulation of the paperboard at the gap between the conveying belt. For example, the patent application No. CN202220569130.7 discloses a pasting box machine conveying buffer mechanism, the roller support of the device has a fixed height and is only adjusted in height by a spring at the roller, and when facing thick corrugated paper, the paperboard may be accumulated at the gap between the roller and the conveying belt, affecting the processing of the corrugated paper by the subsequent equipment. Or for example, the patent application No. CN202420075322.1 discloses a pasting box machine conveying buffer mechanism, the pressing wheel in the device is only adjusted in height by a spring, and has the problems of small adjustment range and unadjustable buffer force, etc. If the thickness of the conveyed paperboard is too thick, the force is too large, and the paperboard is accumulated at the pressing wheel.

[0026] AsFigure 1 The transmission device of a corrugated paper paste box machine is characterized in that a supporting platform 1 is provided with a transmission belt 2 for transmitting corrugated paper, and a buffer assembly is arranged on the supporting platform 1 to slow down the transmission speed of the corrugated paper, wherein the buffer assembly comprises a mounting bracket 3 arranged on the supporting platform 1, an air cylinder 4 arranged on the mounting bracket 3, and a mounting plate 5 arranged at the output end of the air cylinder 4, and a plurality of buffer rollers 6 are arranged on the mounting plate 5 along the transmission direction of the transmission belt 2.

[0027] The width of each buffer roller 6 matches the width of the transmission belt 2, the diameter of the buffer roller 6 located on the feeding side of the transmission belt 2 is smaller than the diameter of the buffer roller 6 located on the discharging side of the transmission belt 2, and the surface of the buffer roller 6 located on the feeding side of the transmission belt 2 is provided with a plurality of flexible protrusions 7.

[0028] Working principle:

[0029] Before the device starts, the cylinder 4 of the buffer assembly is in the retracted state, and the buffer rollers 6 on the mounting plate 5 are in the higher position, not in contact with the corrugated paper on the transmission belt 2. At this time, the transmission belt 2 is kept at a preset high speed under the drive of the motor, ready to receive and transmit the corrugated paper. When the corrugated paper enters the box pasting machine and starts to transmit forward at high speed on the transmission belt 2. In the last process of the box pasting machine, the corrugated paper is output to the transmission belt 2 of the present transmission device at a faster speed. After the multiple buffer rollers 6 come into contact with the corrugated paper, due to the rotational resistance of the buffer rollers 6 and the friction between them and the corrugated paper, a backward force is generated on the corrugated paper, thereby slowing down the transmission speed of the corrugated paper on the transmission belt 2. The width of each buffer roller 6 matches the width of the transmission belt 2, ensuring that the buffer force acts uniformly on the entire width direction of the corrugated paper, avoiding the corrugated paper from being skewed due to uneven force. At the same time, the multiple buffer rollers 6 arranged along the transmission direction form multiple stages of buffering, and each buffer roller 6 slows down the corrugated paper to a certain extent, avoiding the problem of uneven stacking or even misalignment of the corrugated paper due to excessive speed. Since the thickness of the corrugated paper produced in each batch is inconsistent, the buffer wheel can be adjusted within a large range by lifting the cylinder 4. When facing thicker corrugated paper, the piston rod of the cylinder 4 is elongated, driving the buffer roller 6 to descend, ensuring that the buffer roller 6 is in close contact with the corrugated paper and provides sufficient buffer force; if the corrugated paper is thin, the piston rod of the cylinder 4 is shortened, and the buffer roller 6 is raised to the appropriate position, ensuring the buffering effect and preventing excessive extrusion damage to the corrugated paper. At the same time, the front buffer rollers 6 have a smaller diameter than the rear buffer rollers 6, so that the corrugated paper experiences a gradual buffering and deceleration process during transmission. When the corrugated paper first contacts the front buffer roller 6 with a smaller diameter, the flexible protruding part 7 on the buffer roller 6 has a relatively small contact area with the corrugated paper, and the buffer force is relatively weak, so the corrugated paper will first undergo a preliminary and relatively gentle deceleration. As the corrugated paper continues to transmit forward, it contacts the rear buffer roller 6 with a larger diameter, at which time the contact area increases and the buffer force also increases accordingly, achieving further deceleration. This gradual buffering and deceleration method can more smoothly reduce the transmission speed of the corrugated paper.

[0030] In the above technical scheme, the mounting plate 5 is in a U-shaped structure in space, and a sliding groove 8 is formed on the inner side wall of the mounting plate 5 corresponding to the U-shaped structure, and each buffer roller 6 is arranged in the sliding groove 8 through the sliding blocks at both ends of the mounting piece 9 in the U-shaped structure. A plurality of springs 10 are arranged between the top of the mounting piece 9 and the inside of the mounting plate 5. By using this technical method, since the thickness of each batch of corrugated paper is different, when the thicker corrugated paper enters the buffer area, the buffer roller 6 is subjected to an upward force. The buffer roller 6 slides upward in the sliding groove 8 of the U-shaped structure side wall of the mounting plate 5 through the mounting piece 9, and at the same time, the spring 10 between the top of the mounting piece 9 and the inside of the mounting plate 5 is compressed. The elastic force generated after the spring 10 is compressed can make the buffer roller 6 always in good contact with the corrugated paper, and provide stable buffer force. On the other hand, the elastic deformation of the spring 10 can absorb and buffer the impact force caused by the change of the thickness of the corrugated paper, so as to avoid excessive extrusion or damage to the corrugated paper. On the contrary, when thinner corrugated paper is encountered, the elastic force of the spring 10 will push the mounting piece 9 and the buffer roller 6 to slide downward, so as to ensure that the buffer roller 6 can effectively contact the corrugated paper and realize the function of speed reduction.

[0031] In the above technical scheme, the two ends of the buffer wheel are rotatably connected to the side wall corresponding to the mounting piece 9, and the two ends of each buffer wheel are provided with corresponding rotating shafts, and the inner side wall of the mounting piece 9 is provided with bearings matched with the rotating shafts.

[0032] In the above technical scheme, the cleaning assembly 11 is arranged on the support platform 1, and the cleaning assembly 11 is located behind the buffer assembly along the conveying direction. By using this technical method, the corrugated paper after being slowed down by the buffer assembly continues to move forward on the conveying belt 2 to the position where the cleaning assembly 11 is located. The cleaning assembly 11 starts to clean the surface of the corrugated paper.

[0033] In the above technical scheme, the cleaning assembly 11 comprises a dust collection box 12 arranged above the conveying belt 2, and a plurality of cleaning brushes 13 are arranged on the bottom of the dust collection box 12.

[0034] In the above technical scheme, the dust collection box 12 forms negative pressure inside through an external vacuum device, and a plurality of dust suction holes 14 are arranged between each row of cleaning brushes 13 and are in communication with the inside of the dust collection box 12. By using this technical method, when the corrugated paper passes below the dust collection box 12, the cleaning brushes 13 on the bottom of the dust collection box 12 come into contact with the surface of the corrugated paper. The cleaning brushes 13 loosen and separate the dust, fibers and other impurities on the surface of the corrugated paper. Under the action of the plurality of dust suction holes 14 formed on the bottom of the dust collection box 12, due to the pressure difference between the negative pressure inside the dust collection box 12 and the atmospheric pressure outside, the impurities are sucked into the inside of the dust collection box 12 along the direction of the pressure difference. The cleanliness of the corrugated paper is ensured.

[0035] Meanwhile, the dust suction box 12 is arranged above the support platform 1 through a support, and a telescopic assembly (which can be an electric telescopic rod, not shown in the figure) or a spring (not shown in the figure) is arranged between the support and the dust suction box 12; the distance between the dust suction box 12 and the conveying belt 2 can be adjusted according to the thickness of the corrugated paper through the telescopic assembly, and the spring and the brush are matched to passively match the paperboards with different thicknesses.

[0036] In the above technical solution, the density of the cleaning brushes 13 at both ends of the dust suction box 12 is greater than that of the cleaning brushes 13 in the middle; and the multiple rows of brushes are arranged in a wave shape in space. By using this technical method, the brushes at both ends bear more cleaning tasks in the cleaning process, and the relative wear is also more serious. By reasonably increasing the density of the brushes at both ends, the pressure borne by each brush can be relatively uniform, and the premature damage caused by the excessive use of local brushes can be avoided, thereby prolonging the service life of the entire cleaning brush 13, reducing the maintenance cost and the replacement frequency. The wave-shaped arrangement of the brushes can form a kind of sawtooth-like cleaning path during operation, which can better gather dust and sundries near the dust suction hole 14, avoid the scattering of dust to both sides or other directions during the cleaning process, improve the dust suction efficiency, and effectively prevent dust from being missed.

[0037] Although the embodiments of the present application have been disclosed as above, it is not limited to the application listed in the specification and the embodiments, and can be fully applied to various fields suitable for the present application. For those skilled in the art, other modifications can be easily realized, and therefore the present application is not limited to specific details and the figures shown and described herein, without departing from the general concept defined by the claims and the equivalent scope.
