Description

Technical Field

[0001] This utility model relates to a cloth wrapping device, and more particularly to a vacuum cloth wrapping device. Background Technology

[0002] To prevent fabric rolls from being contaminated or damaged during transportation, packaging materials are wrapped around the outside of the rolls, forming a sleeve to protect them. Existing technologies, such as the automatic fabric roll packaging equipment proposed in application number CN202310400151.5, eliminate the need for manual packaging, but have high requirements for the packaging materials. One side of the packaging material needs to be self-adhesive. If self-adhesive packaging materials are used, double-sided tape needs to be manually applied to the packaging material to ensure it is fixed to the fabric roll. When applied to a fabric roll packaging production line, this increases production costs or reduces production efficiency. Therefore, a vacuum wrapping device is proposed. Utility Model Content

It also eliminates the need to purchase packaging material with pre-adhesive backing, reducing the requirements for the packaging material and allowing the edges of the packaging material to adhere to the fabric roll. A reciprocating pulling unit pulls the packaging material from one side of the packaging material feeding mechanism to the other side, where a packaging material cutting unit cuts the material. The rear edge of the packaging material is positioned at the covering channel 702. The fabric roll is then placed on the rotating covering unit, allowing the packaging material to lie flat on the flat adsorption chamber 701. The fabric roll will... The packaging material is pressed down on the rotary covering unit, and the tape on the packaging material adheres to the fabric roll. The rotary covering unit drives the fabric roll to rotate, so that the fabric roll carries the packaging material onto the fabric roll to form a semi-finished product. The feeding swing unit drives the rotary covering unit to swing and feed the semi-finished product, thereby achieving the covering of the fabric roll. It can be applied to the fabric roll slitting production line, eliminating the need for manual packaging of the fabric roll. The air pump is used to extract air from the flat adsorption chamber 701, so that negative pressure is formed at each adsorption hole 703, adsorbing the packaging material covering the flat adsorption chamber 701 and preventing the packaging material from shifting.

[0031] Furthermore, the packaging material feeding mechanism includes a packaging material support, an adhesive application unit, and a clamping and laying unit; the packaging material support includes a docking support 611, a packaging material roll support 603, and a packaging material roll positioning shaft 601; the docking supports 611 of the two packaging material feeding mechanisms are respectively installed on the left and right sides of the work frame 704; the packaging material roll support 603 is installed on the docking support 611; packaging material shaft positioning seats 602 are installed on the upper edges of the front and rear sides of the packaging material roll support 603; the two ends of the packaging material roll positioning shaft 601 are respectively rotatably snapped into the two packaging material shaft positioning seats 602.

[0032] The packaging roll support 603, the packaging roll positioning shaft 601, and the two packaging shaft positioning seats 602 provide positioning and support for the packaging roll and facilitate its rotation. The cooperation between the two sliding support rods 605, the two support rod guide tubes 606, and the positioning shaft support rod 604 provides a certain degree of support for the packaging roll positioning shaft 601.

[0033] Furthermore, the clamping and flattening unit includes a guide roller 624, an edge pressing structure, a flattening and pressing drive structure, and two flattening roller shafts 608; the flattening and pressing drive structure includes two flattening fine-tuning seats and two flattening telescopic push rods 610; the two flattening roller shafts 608 are rotatably and longitudinally mounted on the docking bracket 611, respectively for pressing the packaging material and supporting the packaging material; the guide roller 624 is rotatably and longitudinally mounted on the docking bracket 611; the two flattening fine-tuning seats are vertically and slidably mounted on the front and rear opposite surfaces of the docking bracket 611; a flattening pressing shaft 614 is rotatably and longitudinally connected to the two flattening fine-tuning seats; the two flattening telescopic push rods 610 are respectively used to drive the two flattening fine-tuning seats to slide vertically; multiple flattening pressing rollers 613 for pressing on the guide roller 624 are spaced apart on the flattening pressing shaft 614; the edge pressing structure is mounted on the docking bracket 611 for clamping the wide edge of the packaging material.

[0034] Two flattening rollers 608 are used to press and support the packaging material, so that the packaging material is flattened and passes through the gluing unit, which facilitates the application of glue. The cooperation between the guide roller 624, the flattening pressing shaft 614 and each flattening pressing wheel 613 can play a certain role in clamping and positioning the packaging material to prevent it from shifting. Two flattening telescopic push rods 610 are used to adjust the height of the flattening pressing shaft 614, which facilitates the adjustment of the packaging material position or the replacement of the packaging material.

[0035] Furthermore, the edge pressing structure includes two movable pressing branches, an edge pressing shaft 615 and an edge pressing slide rail 621, as well as multiple fixed pressing branches; the movable pressing branches include a movable pressing shaft sleeve 626 and a movable edge pressing plate 620; the fixed pressing branches include a positioning pressing shaft sleeve 616 and a positioning edge pressing plate 627.

[0036] The edge pressing shaft 615 is rotatably and longitudinally mounted on the docking bracket 611; the edge pressing slide rail 621 is longitudinally connected to the docking bracket 611; the positioning pressing shaft sleeves 616 of each fixed pressing branch are fixed at intervals to the rear of the edge pressing shaft 615; the positioning edge pressing plate 627 is horizontally fixed on the edge pressing slide rail 621 and vertically corresponds to the corresponding positioning pressing shaft sleeve 616; the movable pressing shaft sleeves 626 of the two movable pressing branches are synchronously and longitudinally slidably mounted on the front of the edge pressing shaft 615; the movable edge pressing plate 620 is longitudinally and horizontally mounted on the edge pressing slide rail 621 and vertically corresponds to the corresponding movable pressing shaft sleeve 626.

[0037] Edge pressing rollers 619 are installed on each positioning pressing bushing 616 and the two movable pressing bushings 626 via extension rods 617; edge pressing torsion springs for driving the edge pressing rollers 619 to press against the corresponding positioning edge pressing plates 627 and movable edge pressing plates 620 are installed on the edge pressing shaft 615.

[0038] The edge pressing shaft 615 is rotated by the edge pressing torsion spring, so that the edge pressing rollers 619 on the movable pressing shaft sleeve 626 and the positioning pressing shaft sleeve 616 press on the corresponding movable edge pressing plate 620 and the positioning edge pressing plate 627 respectively, thereby clamping the wide edge of the packaging material. At the same time, the edge pressing rollers 619 can prevent the extension rod 617 from scratching the packaging material while pressing the wide edge of the packaging material.

[0039] Furthermore, the gluing unit includes a gluing adjustment motor 622, a gluing drive screw 623, and a gluing pressing shaft 607; a gluing platform 625 is horizontally mounted in the middle of the docking bracket 611; a gluing adjustment seat 618 is longitudinally slidably mounted on the gluing platform 625; the gluing drive screw 623 is rotatably mounted longitudinally on the gluing platform 625 to drive the gluing adjustment seat 618 to move longitudinally; the gluing adjustment motor 622 is used to drive the gluing drive screw 623 to rotate; a tape roll holder 612 for mounting tape rolls is mounted on both the gluing platform 625 and the gluing adjustment seat 618; the gluing pressing shaft 607 is longitudinally mounted on the docking bracket 611; two pressing rollers 609 are adjustablely mounted on the gluing pressing shaft 607 for pressing on the flattening roller shaft 608 on the upper side, and the two pressing rollers 609 are respectively used to press the tape on both sides of the packaging material tightly.

[0040] The glue application adjustment motor 622 drives the glue application drive screw 623 to rotate. The glue application adjustment seat 618 moves longitudinally under the drive of the glue application drive screw 623, adjusting the position of the rear film roll seat 612. This allows the position of the rear film roll seat 612 to be adjusted according to the width of the packaging material, so that the tape rolls on the two film roll seats 612 can stably provide tape to the front and rear long sides of the packaging material. The pressing roller 609 presses on the two long sides of the packaging material to press the tape tightly on the two long sides of the packaging material, reducing the probability of the tape falling off.

[0041] During the material preparation stage, the wide edge of the packaging material is first pulled to the edge pressing structure, and the upper side of the packaging material is pressed onto the lower flattening roller 608, while the lower side is pressed onto the upper flattening roller 608. Then, the ends of the two tape rolls are manually glued to the front and rear long sides of the lower side of the packaging material between the two flattening rollers 608, with a portion of the tape outside the packaging material. After that, the wide edge of the packaging material is pulled until the packaging material with the tape reaches the edge pressing structure. The packaging material preparation is completed by cutting off the section of packaging material without tape. This allows the tape to follow the packaging material out during the production process, achieving semi-automatic tape application without the need for manual waiting at the vacuum workbench to perform the adhesive application.

[0044] The reciprocating gripping drive motor 706 drives one of the reciprocating moving drive shafts 705 to rotate through the pull synchronous belt drive pair, so that the two reciprocating synchronous belt drive pairs drive the two reciprocating gripping moving seats 707 to move laterally in sync. This causes the reciprocating gripping plate 717 to drive the two gripping execution structures to move laterally reciprocally, causing the packaging material to partially cover the upper side of the flat adsorption chamber 701, which facilitates the packaging material to be wrapped on the fabric roll to form a semi-finished product.

[0054] Furthermore, the rotary covering unit includes a covering active idler roller 723, a covering driven idler roller 724, and a covering rotary drive motor 727;

[0055] The active coating roller 723 is rotatably and laterally mounted on the work frame 704 and located below the coating channel 702. The coating rotation drive motor 727 drives the active coating roller 723 to rotate via a coating synchronous belt drive pair. The driven coating roller 724 is rotatably and laterally mounted on the unloading swing unit and is synchronously connected to the active coating roller 723 via a coating transmission belt drive pair.
