Description

Technical Field

[0001] The utility model relates to the technical field of packaging cross-cutting equipment, in particular to a roller cross-cutting mechanism for a condensed bead packaging machine. Background Art

[0002] Laundry beads are a type of laundry product that concentrates ingredients such as detergent, softener, and disinfectant in a small bead. It can be directly put into the washing machine for washing clothes without pre-dissolving or measuring. When producing and processing laundry beads, the laundry detergent needs to be injected into the base film in the mold cavity, and then the mask is covered on the base film to seal the film to form a bead shape. After the beads are sealed and packaged, the beads are connected to the continuous film one by one, and a cutting mechanism is required to divide the beads from the continuous mold into independent beads, including longitudinally cutting the beads integrated with the continuous mold into strips, and then cross-cutting the strips to form independent beads.

[0003] The prior art uses a cross-cutting device to perform transverse cutting of the packaged condensed beads. During the cutting process, the mold and the continuous film attached thereto rotate continuously. The cross-cutting knife of the cross-cutting device needs to be consistent in speed with the contact point of the continuous film during cutting, and needs to press the continuous film and the condensed beads on it onto the surface of the molding mold. The cross-cutting knife is used to cut and separate them, thereby dividing the condensed beads connected in strips into independently packaged condensed beads. In the existing cross-cutting device, the condensed beads are easily moved by the cutting force when the cutter cuts the condensed beads, resulting in inaccurate cutting position. For example, in the prior art, Chinese Patent Publication No. CN218113234U discloses a cutting device for the production and preparation of laundry condensed beads, in which a pressing component and a cross-knife roller are both arranged on a movable frame, and the cutter moves with the pressing component, so that the pressing component does not press the condensed beads on the continuous film tightly before the cutter starts cutting. It is easy for the product to not be pressed, causing the product to jump and move, resulting in inaccurate cutting position, affecting the quality of the product and the continuity of production, and failing to meet the needs of efficient production. Therefore, improvements are needed to meet production needs. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] It should be noted that all directional indications in the embodiments of the present invention (such as up-down-left-right-front-back...) are only used to explain the relative position relationship - movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0025] like Figure 1-Figure 7 As shown, a roller cross-cutting mechanism of a condensed bead packaging machine includes a bottom plate 1, a roller 23 assembly 2 is slidably connected to the bottom plate 1, and the roller 23 assembly 2 includes a translation plate 21, and the translation plate 21 and the bottom plate 1 form a sliding fit through a linear slide rail. A first cylinder 3 is installed on the bottom plate 1, and the piston rod end of the first cylinder 3 is connected to the translation plate 21 to drive the translation plate 21 to move on the bottom plate 1; the two ends of the translation plate 21 are fixedly connected to the vertical plates 22, and the two sides of the translation plate 21 are A plurality of pressure rollers 23 are rotatably connected between the vertical plates 22, and the plurality of pressure rollers 23 are arranged in an arc shape and fit onto the outer surface of the forming mold 9 for making condensed beads so as to press the condensed beads on the forming mold 9 into the forming mold 9; a mounting plate 24 is fixedly connected to the translation plate 21, and a cutter assembly 4 is slidably connected to the mounting plate 24, and a second cylinder 25 for driving the cutter assembly 4 to move is installed on the mounting plate 24, and the cutter assembly 4 includes a cross-cutting blade 41 for cutting the condensed beads.

[0026] By adopting the above technical scheme, the base plate 1 is installed on the frame of the condensed bead packaging machine and driven by the first cylinder 3, so that the translation plate 21 and the auxiliary components are moved closer to the forming mold 9 for making condensed beads, and the pressure roller 23 abuts against the forming mold 9 and presses the condensed beads into the forming mold 9. The pressure roller 23 rotates and follows the rotation of the forming mold 9 to rotate and keep the condensed beads pressed. The rotation of the pressure roller 23 can reduce the resistance during the rotation of the forming mold 9; the second cylinder 25 drives the cutter assembly 4 to move toward the condensed beads, so that the cross-cutting blade 41 cuts the connected condensed beads into single particles, and the condensed beads are squeezed by the pressure roller 23 to maintain a relatively stable position during the cutting process, thereby avoiding the condensed beads from jumping and moving, improving product quality, and reducing production failures; when it is necessary to replace the cross-cutting blade 41 or other maintenance, the piston rod is driven to retract by the first cylinder 3, so that the translation plate 21 and the auxiliary components are away from the forming mold 9, which is convenient for maintenance.

[0027] Specifically, the cutter assembly 4 includes a movable plate 42, the piston rod end of the second cylinder 25 is fixedly connected to the movable plate 42, the two ends of the movable plate 42 are fixedly connected to bearing seats 43, the bearing seat 43 is rotatably connected to a cross-cutting shaft 44 through a bearing, the cross-cutting shaft 44 is fixedly connected to a cutter seat 45, the cross-cutting blade 41 is installed on the cutter seat 45, and the cross-cutting blade 41 is located in a gap formed by adjacent pressure rollers 23; a servo motor 46 is installed at one end of the movable plate 42, the rotating shaft of the servo motor 46 is fixedly connected to a first gear 47, the end of the cross-cutting shaft 44 is fixedly connected to a second gear 48, the first gear 47 and the second gear 48 are driven by gear meshing, and the servo motor 46 drives the cross-cutting shaft 44 to rotate through gear transmission to drive the cross-cutting blade 41 to rotate. The servo motor 46 drives the cross-cutting shaft 44 to rotate at a certain angle at a set speed, so that the cross-cutting blade 41 rotates during cutting, so that the tangential speed of the cross-cutting blade 41 at the contact point with the continuous film during cutting remains consistent, so that the position between the cross-cutting blade 41 and the continuous film remains relatively stable during cutting; the second cylinder 25 drives the cross-cutting blade 41 to extend to cut the continuous film, and after the cutting is completed, the second cylinder 25 drives the cross-cutting blade 41 to retract and reset. After the cross-cutting blade 41 is reset, the servo motor 46 reverses to drive the cross-cutting blade 41 to rotate and reset.

[0028] Specifically, the cutter seat 45 is provided with mounting holes arranged along the length direction of the cutter seat 45, and a cross-cutting heating rod 49 is installed in the mounting hole. The cross-cutting heating rod 49 is connected to an external power source, and the cross-cutting heating rod 49 generates heat so that the cross-cutting blade 41 has a certain temperature during cutting, and the continuous film is hot-cut during slitting, so that the cutting is faster and neater.

[0029] Specifically, the cutter seat 45 is provided with a step surface 451, the cross-cutting blade 41 is fitted on the step surface 451, a pressing plate 410 is fixed above the cutter seat 45 by bolts, and a first pressing boss 4101 and a second pressing boss 4102 protruding downward are provided on the pressing plate 410, the first pressing boss 4101 abuts against the upper surface of the cross-cutting blade 41, and the second pressing boss 4102 abuts against the upper end of the cutter seat 45. By providing the first pressing boss 4101 and the second pressing boss 4102 protruding downward on the pressing plate 410, there is a suspended gap between the middle of the pressing plate 410 and the cutter seat 45, so that when the thickness of the cross-cutting blade 41 changes when it is replaced, the first pressing boss 4101 can still clamp the cross-cutting blade 41, thereby improving adaptability.

[0030] Specifically, a mounting block 5 is fixed on the vertical plate 22, a sealing plate 6 is provided on the mounting block 5, a locking bolt 7 is provided on the sealing plate 6, and the locking bolt 7 locks the sealing plate 6 on the mounting block 5, and the sealing plate 6 covers the area between the vertical plates 22 at both ends of the translation plate 21. The cutting blade assembly 4 between the vertical plates 22 is covered by the sealing plate 6, thereby preventing foreign matter from entering the area between the vertical plates 22 and causing interference in the slitting process.

[0031] Specifically, the side of the movable plate 42 close to the cross-cutting shaft 44 is fixedly connected to a limiting plate 8, and a U-shaped groove 81 is formed on the limiting plate 8, and the open side of the U-shaped groove 81 faces the cross-cutting shaft 44, and the cross-cutting shaft 44 passes through the U-shaped groove 81. By providing the limiting plate 8, when the cross-cutting shaft 44 rotates too much during debugging, the cutter seat 45 contacts the limiting plate 8, thereby limiting the cross-cutting shaft 44 from rotating too much, causing the cutter seat 45 to collide with the servo motor 46 and damage it.
