Description

Technical Field

[0001] The utility model relates to the technical field of bottle embryo box packaging equipment, and in particular to a semi-automatic bottle embryo box packaging equipment. Background Art

[0002] At present, the preforms in the blow molding workshop are packed in woven bags, which are manually supported, filled, and sewn, and then moved to the designated location. This process requires the cooperation of two operators, one for supporting and one for filling. The disadvantage of manual bagging is low work efficiency. The packed preforms are relatively loose. During the subsequent handling and transportation, the mouth of the preform is easily damaged, resulting in the subsequent bottle blowing operation being unable to proceed and becoming waste. In order to save manpower and labor, it is urgent to design a preform packaging equipment. Utility Model Content

[0003] The utility model aims to solve the above-mentioned deficiencies in the prior art and to provide a semi-automatic preform boxing device. The equipment uses a heat shrink film process to form a rectangular box of preforms that are tightly arranged and not easy to loosen, thereby saving manpower and making the preforms tightly packed and not easy to damage.

[0004] The technical solution of the utility model is as follows:

[0005] A semi-automatic preform boxing device, comprising a preform boxing mechanism, a preform film wrapping mechanism, and a preform film shrinking mechanism arranged in sequence, characterized in that: the preform boxing mechanism comprises a workbench I with a conveyor belt I installed on the top, a box positioning frame is arranged above the conveyor belt I, the box positioning frame is fixed on the workbench I, and a flip frame is also arranged on the workbench I, the flip frame is installed above the box positioning frame through a movable joint, and a mold plate is arranged in the flip frame;

[0006] A preform film wrapping mechanism is arranged at the rear end of the conveyor belt I, and the preform film wrapping mechanism includes a workbench II with a conveyor belt II installed on the top, a fixed frame is arranged upward from the workbench II, a vertical cylinder is arranged on the fixed frame, a hot melt knife is connected to the power output end of the cylinder, a film roll placement shaft is also arranged on the fixed frame, and a cutting groove is arranged on the workbench II directly below the hot melt knife;

[0007] The preform shrinking mechanism comprises a shrinking shell, in which a mesh chain conveying assembly is arranged. The conveying surfaces of the mesh chain conveying assembly, conveyor belt I and conveyor belt II are kept at the same horizontal plane.

[0008] Preferably, a roller platform is arranged at the rear end of the preform shrinking mechanism, and a plurality of rollers II are arranged on the upper surface of the roller platform.

[0009] Preferably, a slide plate is connected to the rear end of the roller platform, and the slide plate is provided with a downward inclination angle, so that the boxed preforms slide off the roller platform, which is convenient for subsequent handling operations.

A vertical limit groove is arranged on the front of the connecting plate. A limit block is arranged on the side of the flip frame. The limit block is arranged in the limit groove. The side of the connecting plate is hinged to one end of the active rod I. One end of the active rod II is hinged to the middle of the active rod I, and the other end is also hinged to the middle of the flip frame. The combination of the limit groove and the limit block plays the effect of supporting one end of the flip frame, and at the same time limits the flip frame to move only in the vertical direction along the limit groove. The active rod I is an active rod and the active rod II is a driven rod.

After the height of the flip frame is determined, the support plate is rotated to be exposed from the bottom of the flip frame to support the mold plate in a horizontal position; when the mold plate needs to be flipped, the support plate is rotated to be hidden in the flip frame so as not to block the flipping of the mold plate, and after the flipping is completed, the support plate is rotated again to be exposed from the bottom of the flip frame to support the other side of the mold plate.

[0014] Preferably, the mold plate is provided with mold holes with the same number in each single row and the adjacent rows being staggered and arranged in a matrix shape overall.

[0015] Preferably, the fixed frame includes a support beam I and a support beam II, a vertical cylinder is fixed to the support beam II, a hot melt knife is connected to the power output end of the cylinder, a film roll placement shaft is provided on the support beam I, a film roll is installed on the film roll placement shaft, a small roller group is also provided on the fixed frame, a cutting groove is provided on the workbench II directly below the hot melt knife, and the film roll is fixed on the cutting groove through the small roller group.

[0016] Preferably, the small roller group includes three groups of rollers I arranged in sequence from top to bottom, and the rotation axis of each roller I is in the same direction as the rotation axis of the film roll placement shaft.

[0017] A power motor I is arranged on the workbench I, a transmission gear I is connected to the output end of the power motor I, a driven gear I is arranged on the conveyor belt I, a chain I is arranged between the transmission gear I and the driven gear I, and the power motor I provides driving force for the conveyor belt I.

The opening of the box positioning frame 3 points to the rear end of the conveyor belt Ⅰ1, so that the boxed preforms 36 can be easily transferred to the preform wrapping mechanism through the conveyor belt Ⅰ1 after transfer.

[0053] Workflow:

[0054] The storage frame 34 is filled with a number of qualified preforms 35. The operator pulls the movable joint 5 to lower the mold plate 6 to a position level with the box positioning frame 3. The upper packaging box is placed in the box positioning frame 3. With the help of the positioning of the mold plate 6, 27 preforms 35 with the bottle mouth facing downward are placed in the packaging box. The movable joint 5 is pulled to raise the mold plate 6, which is turned 180 degrees. The movable joint 5 is then pulled to lower the mold plate 6 to the bottom of the placed preforms 35. Under the action of the mold plate 6, 27 preforms 35 with the bottle mouth facing upward are placed. The movable joint 5 is then pulled to raise the mold plate 6. At this time, the boxed preforms 36 are already loaded. The conveyor belt 1 is turned on, and the boxed preforms 36 move forward and enter the preform wrapping mechanism.

[0055] It should be noted that when a new packaging box is loaded with preforms 35 for the first time, since the packaging box is empty at this time, the movable joint can send the flip frame 4, i.e., the mold plate 6, to a position lower than the height of the preforms 35, so as to facilitate the first placement of the preforms from above the mold plate. After the first loading is completed, when the mold plate is raised, reversed, and then dropped, the preforms placed for the first time will press against the mold plate, i.e., the mold plate can only be lowered to the height of the top of the preforms for the second time, and then the second wave of preforms can be placed from top to bottom.

[0056] After one end of the roll film 27 is guided by the small roller group 28, it sticks to the cutting groove 13. During the movement of the boxed preform 36 from the conveyor belt 1 to the conveyor belt 2, the roll film 27 wraps around the entire boxed preform 36. At this time, the hot melt knife 11 is driven by the cylinder 10 to descend and melt the roll film 27 at the cutting groove 13. The cylinder 10 rises and lifts the hot melt knife 11. The boxed preform 36 wrapped with the roll film 27 continues to move forward, and the remaining roll film 27 is still stuck to the cutting groove 13.

[0057] The boxed preforms 36 wrapped with the roll film 27 enter the preform shrinking mechanism, and the shrinking effect is achieved under the action of the preform shrinking mechanism components such as the fan, the heating component and the lamp group.

[0058] The finished products of shrink film are temporarily placed at the roller table. The arrival of the next group of finished products promotes the advancement of the previous group of finished products, slides down along the slide plate 18, and after accumulating several boxes, they are manually transported to the storage location.
