Description

Technical Field

[0001] The invention relates to the technical field of packaging and stacking, and in particular to a layered stacking device for preparing wet wipes. Background Art

[0002] In the production of wet wipes, a whole wet wipe is first cut into pieces, and then the cut wet wipes are placed on two parallel conveyor belts. After moving to the position of the pushing device, the pushing device pushes the wet wipes off the conveyor belt, causing the wet wipes to fall onto the receiving table for stacking. After stacking to a certain thickness, they are packaged.

[0003] The Chinese patent document with the authorization announcement number CN209777591U discloses a stacking mechanism of a wet wipes production line, including a first conveyor belt and a conveying platform located at the rear side of a cutting mechanism, a stacking discharge port is provided on the conveying platform, a first stacking belt and a second stacking belt are provided on the conveying platform directly below the stacking discharge port, and both are driven to rotate by a driving motor, a delay relay is connected to the driving motor, the first stacking belt rotates in the opposite direction to the second stacking belt, stacking rods are provided on the surfaces of the first stacking belt and the second stacking belt, the first stacking belt and the second stacking belt are respectively located on both sides of the stacking discharge port, a second conveyor belt parallel to the first conveyor belt is installed between the first stacking belt and the second stacking belt, a conveying gear rod is fixedly provided on the surface of the second conveyor belt, and the width of the second conveyor belt is less than the distance between the stacking rods on the first stacking belt and the second stacking belt close to each other at one end. The cut wet wipes can be stacked steadily, and the wet wipes are not likely to be scattered.

[0004] In the prior art, since the pushing device needs to pass between the two conveyor belts, the pushing device only contacts the middle part of the wet wipes. Therefore, when the pushing device pushes the wet wipes off the conveyor belt, the two ends of the wet wipes tilt upward due to inertia. Therefore, after the wet wipes fall onto the receiving table, wrinkles are easily formed on the two ends of the wet wipes, causing the two ends of the wet wipes to be higher, affecting the subsequent packaging. Summary of the invention

[0005] The present invention provides a layered stacking device for preparing wet wipes, aiming to solve the problem in the related art that after the wet wipes fall onto a receiving table, wrinkles are easily formed at both ends of the wet wipes, causing the two ends of the wet wipes to be higher.

[0006] The trolley assembly is a device for stacking wet wipes according to claim 1, wherein the two ends of the wet wipes are stacked on the two conveyor belts, the two ends of the wet wipes are respectively straddling the two conveyor belts, a receiving platform is provided at the bottom of one end of the conveyor belt, and a pushing device is provided between the two conveyor belts, the pushing device comprises a telescopic driving member 1 installed above the conveyor belt, the telescopic end of the telescopic driving member 1 is installed with a connecting rod assembly, an isolation belt is installed on the connecting rod assembly, both ends of the isolation belt are elastically connected on both sides of the connecting rod assembly, the bottom of the connecting rod assembly has two moving ends that move in a mirror direction, the inner side of the isolation belt is abutted against the moving end of the connecting rod assembly, so that the part of the isolation belt between the two moving ends is a horizontal section, and the connecting rod assembly has an expanded state and a contracted state. In the contracted state, the distance between the two moving ends is the smallest, and the length of the horizontal section of the isolation belt is less than the gap width between the two conveyor belts. In the expanded state, the distance between the two moving ends is the largest, and the length of the horizontal section of the isolation belt is greater than the length of the wet wipes.

[0007] The effect is as follows: when the wet wipes move to the bottom of the isolation belt, the telescopic drive member extends, so that the isolation belt contacts the middle part of the wet wipes and continues to push downward, so that the two ends of the wet wipes are separated from the conveyor belt, and the two moving ends at the bottom of the connecting rod assembly move away from each other, thereby lengthening the horizontal section of the isolation belt so that the horizontal section of the isolation belt can completely cover the wet wipes. After the distance between the wet wipes and the receiving platform is reduced to a certain extent, the telescopic drive member contracts, and the wet wipes fall onto the receiving platform under the action of inertia, thereby avoiding unevenness at both ends of the wet wipes after stacking.

[0008] Preferably, the connecting rod assembly includes connecting rod one and connecting rod two hinged on the telescopic end of a telescopic driving member, the two ends of the isolation belt are elastically connected to connecting rod one and connecting rod two, respectively, the bottom ends of connecting rod one and connecting rod two are rotatably installed with a rotating shaft that is against the inner side of the isolation belt, and the connecting rod assembly also includes a driving mechanism for adjusting the angle between connecting rod one and connecting rod two, the effect of which is: the angle between connecting rod one and connecting rod two is changed by the driving mechanism, so that the spacing between the rotating shafts is changed, thereby changing the length of the horizontal section of the isolation belt.

[0009] Preferably, the driving mechanism includes two hinged connecting rods three, a telescopic driving member two is installed on the telescopic end of the telescopic driving member one, the telescopic end of the telescopic driving member two is connected to the hinged joints of the two connecting rods three, and the other ends of the two connecting rods three are respectively hinged to the connecting rod one and the connecting rod two.

[0010] Preferably, the isolation belt is a water-absorbent cloth, which has the effect of absorbing excess water on the wet wipes.

[0011] Preferably, the outer sides of the connecting rod 1 and the connecting rod 2 are both provided with a wiper assembly for scraping off excess water on the isolation belt, and the effect thereof is that the water adsorbed on the isolation belt is scraped off by the wiper assembly.

[0012] Preferably, the wiper assembly includes a connecting rod fixedly connected to connecting rod one or connecting rod two, a scraper is hinged on the connecting rod, the scraper is inclined upward and a torsion spring is installed between the connecting rod and the scraper, and an isolation belt passes between the scraper and the rotating shaft. The effect is that when the isolation belt passes against the inclination direction of the scraper, the scraper scrapes off a portion of the water adsorbed on the isolation belt.

[0013] Preferably, both ends of the isolation belt are connected with elastic belts, and the elastic belts at both ends are respectively connected to the connecting rod 1 and the connecting rod 2.

[0014] Preferably, the telescopic driving member 1 and the telescopic driving member 2 are both pneumatic rods.

[0015] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0016] When the wet wipes move under the isolation belt, the telescopic drive member 1 extends, so that the isolation belt contacts the middle part of the wet wipes and continues to push downward, so that the two ends of the wet wipes are separated from the conveyor belt. When the connecting rod 1 and the connecting rod 2 move under the conveyor belt, the telescopic drive member 2 extends to increase the angle between the two connecting rods 3, thereby increasing the angle between the connecting rod 1 and the connecting rod 2, so that the horizontal section of the isolation belt can completely cover the wet wipes. After the distance between the wet wipes and the receiving platform is reduced to a certain extent, the telescopic drive member 1 contracts, and the wet wipes fall onto the receiving platform under the action of inertia, thereby avoiding unevenness at both ends of the wet wipes after stacking.

[0024] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0025] like Figure 1-Figure 5 As shown, a layered stacking device for preparing wet wipes includes two parallel conveyor belts 2, with the two ends of the wet wipes respectively straddling the two conveyor belts 2, a receiving platform 3 is provided at the bottom of one end of the conveyor belt 2, and a pushing device 1 is provided between the two conveyor belts 2.

[0026] The pushing device 1 includes a telescopic driving member 11 (which can be a pneumatic rod or a hydraulic rod) installed above the conveyor belt 2. A fixed shaft is fixedly arranged on the telescopic end of the telescopic driving member 11, and a connecting rod assembly 12 is installed on the fixed shaft. The connecting rod assembly 12 includes two pairs of connecting rods 121 and 122 hinged on the fixed shaft. The two ends of the isolation belt 13 are connected to the connecting rod 121 and the connecting rod 122 through elastic belts 131. The bottom ends of the connecting rods 121 and 122 are rotatably installed with a rotating shaft 123 that abuts against the inner side of the isolation belt 13. The diameter of the rotating shaft 123 is the same as the width of the connecting rod 121 or the connecting rod 122. The rod assembly 12 also includes a driving mechanism for adjusting the angle between the connecting rod 1 121 and the connecting rod 2 122, the driving mechanism includes two hinged connecting rods 3 124, a telescopic driving member 2 125 (which can be a pneumatic rod or a hydraulic rod) is installed on the telescopic end of the telescopic driving member 11, the telescopic end of the telescopic driving member 2 125 is connected to the hinged part of the two connecting rods 3 124, and the other ends of the two connecting rods 3 124 are respectively hinged to the connecting rod 1 121 and the connecting rod 2 122, and the angle between the two connecting rods 3 124 is changed by telescoping the telescopic driving member 2 125, thereby changing the angle between the connecting rod 1 121 and the connecting rod 2 122.

[0027] An isolation belt 13 is provided at the bottom of the connecting rod assembly 12, and both ends of the isolation belt 13 are connected to the outside of the connecting rod 121 and the connecting rod 2 122 through elastic belts 131. The inner side of the isolation belt 13 is against the rotating shaft 123, so that the isolation belt 13 is U-shaped, so that the part of the isolation belt 13 located between the two rotating shafts 123 is a horizontal section, and the connecting rod assembly 12 has an expanded state and a contracted state. When the connecting rod assembly 12 is located between the conveyor belts 2, it is in a contracted state, the distance between the two rotating shafts 123 is the smallest, and the length of the horizontal section of the isolation belt 13 is less than the gap width between the two conveyor belts 2. When the connecting rod assembly 12 is located below the conveyor belt 2, it is in an expanded state, the distance between the two rotating shafts 123 is the largest, and the length of the horizontal section of the isolation belt 13 is greater than the length of the wet wipes.

[0028] Working principle: When the wet wipes move to the bottom of the isolation belt 13, the telescopic driving member 11 extends, so that the isolation belt 13 contacts the middle part of the wet wipes and continues to push downward, so that the two ends of the wet wipes are separated from the conveyor belt 2. When the connecting rod 121 and the connecting rod 2 122 move to the bottom of the conveyor belt 2, the telescopic driving member 2 125 extends to increase the angle between the two connecting rods 3 124, thereby increasing the angle between the connecting rod 1 121 and the connecting rod 2 122, so that the horizontal section of the isolation belt 13 can completely cover the wet wipes. After the distance between the wet wipes and the receiving platform 3 is reduced to a certain extent, the telescopic driving member 11 contracts, and the wet wipes fall onto the receiving platform 3 under the action of inertia, thereby avoiding unevenness at both ends of the wet wipes after stacking.

[0029] Since wet wipes may become overly wet, the following settings are made to prevent wet wipes from becoming overly wet before packaging;

[0030] The isolation belt 13 is an absorbent cloth, and the outer sides of the connecting rod 121 and the connecting rod 2 122 are provided with a wiper assembly 4 for scraping off excess water on the isolation belt 13. The wiper assembly 4 includes two connecting rods 41 respectively fixedly connected to the connecting rod 121 and the connecting rod 2 122. A scraper 42 is hinged on the connecting rod 41. The scraper 42 is inclined upward and a torsion spring is installed between the connecting rod 41 and the scraper 42. The torsion spring applies a downward rotation force to the scraper 42, and the isolation belt 13 passes between the scraper 42 and the rotating shaft 123.

[0031] Working principle: when the horizontal section of the isolation belt 13 completely covers the wet wipes, since the isolation belt 13 is in accelerated motion, the excess moisture on the wet wipes is absorbed by the isolation belt 13. When the connecting rod assembly 12 is reset, the isolation belt 13 is pulled and reset by the elastic belt 131. The elastic belt 131 moves along the inclination direction of the scraper 42, and the scraper 42 flips upward. Therefore, the pressure of the scraper 42 on the elastic belt 131 is relatively small. When the connecting rod 121 and the connecting rod 2 122 are unfolded again, the elastic belt 131 moves against the inclination direction of the scraper 42, so that the scraper 42 flips downward, and the gap between the scraper 42 and the rotating shaft 123 becomes smaller, so that the moisture on the isolation belt 13 is squeezed down, and then flows out from both ends of the rotating shaft 123.

[0032] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
