Description

Technical Field

[0001] The present invention relates to an automatic film winding packaging machine, belonging to the technical field of packaging machines. Background Art

[0002] A packaging machine is a tool for packaging products. Existing packaging machines are all rotary long cantilever type film winding packaging products for large-volume packages, and cannot achieve film winding packaging for small-diameter and small-volume products. When placing a product to be packaged on an existing packaging machine, it is necessary to position it, and then wind a packaging film on the product. The positioning of products by existing packaging machines is relatively difficult. Some packaging machines even do not have relevant devices for positioning. During use, it is necessary to manually position the product and then wind the packaging film. Moreover, since existing packaging machines wind and package products in a rotary long cantilever manner, before packaging the product, the product needs to be placed on the cantilever, and most of this placement process cannot be automated, making the entire process unable to achieve automated processing, resulting in low packaging efficiency of the product.

[0003] Secondly, since existing packaging machines use long-arm winding and place the product on the cantilever, the fixation of the product is relatively difficult, and the product is also prone to swing during the packaging process, making it difficult to effectively improve the packaging quality of the product. Summary of the Invention

[0004] The object of the present invention is to provide an automatic film winding packaging machine to solve the technical defect in the prior art that film winding packaging for small-diameter and small-volume products cannot be achieved.

The driving motor is used to drive the material fixing frame to rotate on the frame; the film cutting device is installed on the frame and is used to cut the film after the film winding is completed. In the present invention, the film unwinding device is used for unwinding the film, the material fixing frame is used to place the material, and the material rotates with the material fixing frame to wind the film on the material. The film cutting device cuts the film to achieve subsequent winding. The present invention is applicable to film winding packaging of small-diameter materials. The present invention can be used on a packaging production line.

The tops of the four support columns 102 are respectively detachably connected to the four corners of the upper horizontal support plate 101, such as by screw connection, etc., for supporting the upper horizontal support plate 101 from the bottom. A first circular through hole penetrating the upper and lower parts is opened on the upper horizontal support plate 101. The lower horizontal support plate 103 is detachably connected to the four horizontal support plates 103. Specifically, on two opposite sides of the lower horizontal support plate 103, mounting protrusions 104 protrude in the direction away from each other. On the side of the mounting protrusion 104 away from the lower horizontal support plate 103, a first mounting groove with a semi-circular cross-section matching the support column 102 is opened. A fixing block 105 is detachably mounted on the mounting protrusion 104 by bolts. A second mounting groove matching the support column 102 is provided on the side of the fixing block 105 close to the mounting protrusion 104. When the fixing block 105 is mounted on the mounting protrusion 104, the first mounting groove and the second mounting groove form a mounting hole, and the support column 102 is clamped in the mounting hole to realize the detachable mounting of the lower horizontal mounting plate 103 and the support column 102. A second circular through hole penetrating the upper and lower parts is opened on the lower horizontal mounting plate 103, and the center line of the second circular through hole is collinear with that of the first circular through hole.

When the piston rod of the unwinding driving device 27 extends, it drives the unwinding mounting frame 26 and the film placed on the unwinding mounting frame 26 to move upward to raise the height of the film. When the piston rod of the unwinding driving device 27 contracts, it drives the unwinding mounting frame 26 and the film placed on the unwinding mounting frame 26 to move downward to lower the height of the film.

[0024] The film winding device 3 described in the present invention includes a material fixing frame 4 and a driving motor 5. The material fixing frame 4 is rotatably arranged on the machine frame 1 and is used to fix the material during film winding. In the present invention, a rotating shaft 33 is installed at the bottom of the material fixing frame 4. The rotating shaft 33 passes downward through the second circular through hole on the lower horizontal support plate 103 and is rotatably connected to the second circular through hole by a bearing to achieve the rotational connection between the material fixing frame 4 and the machine frame 1. The driving motor 5 is used to drive the material fixing frame 4 to rotate on the machine frame 1. In the present invention, the driving motor 5 is detachably installed on the lower horizontal support plate 103 by bolts. The output shaft of the driving motor 5 passes downward through the lower horizontal support plate 103, and a driving pulley is arranged on the output shaft of the driving motor 5. A driven pulley is installed at the position of the rotating shaft 33 below the lower horizontal support plate 103. The driving pulley and the driven pulley are connected by a transmission belt. In the present invention, a protective cover 34 is detachably installed on the lower surface of the lower horizontal support plate 103 by screws to cover the transmission belt in the protective cover 34 to improve the safety of using the present invention; the film cutting device 6 is installed on the upper surface of the upper horizontal support plate 101 of the machine frame 1 and is used to cut the film after the film winding is completed. When the present invention is in use, the material is placed on the material fixing frame 4. The driving motor drives the material fixing frame 4 to rotate relative to the machine frame. The material on the material fixing frame 4 rotates synchronously. The film on the unwinding device 2 is wound around the material as the material rotates. When the material rotates one circle with the material fixing frame 4, the film winds around the material one circle. The film cutting device 6 cuts the film to complete the process of winding the film on the material.

The material conveying device 8 is installed on the material fixing frame 4 and is used to convey the material in the direction of the positioning protrusion; in the present invention, the material is conveyed on the material conveying device 8 in the direction of the material positioning member until it abuts against the positioning protrusion and is blocked by the material positioning member. When it can no longer be conveyed, the positioning of the material is completed. In the present invention, the sides of the two positioning protrusions away from the material positioning member are located on a circle with a point on the rotating shaft of the material fixing frame 4 as the center of the circle.

[0026] The material conveying device 8 described in the present invention includes a conveying support plate 13, a conveyor belt 14, and a conveying motor 15; the conveying support plate 13 is installed above the material fixing frame 4 by two parallel conveying support frames and can rotate synchronously with the rotation of the film winding device 3; the number of the conveyor belts 14 is two, and one conveyor belt 14 is arranged at each conveying support frame.

The fixing plate driving device 19 in the present invention is a fixing plate driving cylinder with two piston rods that synchronously extend and retract and is installed on the material fixing plate 17. The cylinder body of the fixing plate driving device 19 is detachably installed on the material fixing plate 17 by bolts. The piston rod of the fixing plate driving device 19 is arranged upward and vertically extends and retracts. The material fixing plate 17 is installed at the end of the piston rod of the fixing plate driving device 19. The piston rod of the fixing plate driving device 19 extends or retracts to drive the material fixing plate 17 to move upward or downward; the material fixing suction cup 18 is installed on the material fixing plate 17 and is used to adsorb materials during use to fix the materials on the material fixing plate 17.

[0028] The cutting film device 6 described in the present invention includes a cutting driving device 24 and a cutter 25; the cutting driving device 24 is installed on the frame 1, and the cutting driving device 24 described in the present invention is a cylinder that is detachably installed on the upper horizontal support plate 101 by bolts; the cutter 25 is installed on the piston rod of the cutting driving device 24 and is driven by the cutting driving device 24 to move towards or away from the material for cutting the film. The length direction of the cutter 25 is consistent with the vertical direction. In the present invention, when the piston rod of the cutting driving device 24 extends, it drives the cutter 25 to move towards the material for cutting the film; when the piston rod of the cutting driving device 24 contracts, it pulls the cutter 25 in the direction away from the material, so that the cutter 25 is away from the material, avoiding scratching or accidentally cutting the film when winding the film on the material.

[0029] The present invention is also provided with a film clamping device 20, which includes a first film clamping driving device 21, a clamping rod 22 and a second film clamping driving device 23; the first film clamping driving device 21 is installed on the material fixing frame 4 and can move vertically on the material fixing frame 4. In the present invention, the first film clamping driving device 21 preferably uses a pneumatic finger; the two clamping rods 22 are installed on the two clamping jaws of the first film clamping driving device 21 and rotate towards or away from each other with the rotation of the clamping jaws of the first film clamping driving device 21 for clamping or loosening the film; the second film clamping driving device 23 is installed on the material fixing frame 4 and is used to drive the first film clamping driving device 21 to move vertically. The second film clamping driving device 23 preferably uses a double-acting cylinder, and the body of the double-acting cylinder is detachably installed on the material fixing frame 4 by bolts. The body of the first film clamping driving device 21 is detachably installed on the baffle at the piston end of the double-acting cylinder, and the piston of the double-acting cylinder expands and contracts to drive the first film clamping driving device 21 to move up and down.

[0030] The present invention is also provided with a film path positioning device 7, which includes a positioning roller 28, a fixed column 29 and a pressure roller 31; the positioning roller 28 is vertically arranged, and its bottom end is set on the frame 1; the bottom end of the fixed column 29 is set on the frame 1, and a connecting frame 30 is arranged on the fixed column 29. The connecting frame 30 is in a "C" shape; the pressure roller 31 is vertically arranged, and its bottom end and top end are both rotatably connected to the connecting frame 30. When in use, the pressure roller 31 presses the film against the positioning roller 28 and enables the film to be conveyed between the pressure roller 31 and the positioning roller 28.

[0031] The working process of the present invention is as follows: Materials automatically enter the upper horizontal support plate 101 from the flow packaging line. At this time, the piston rod of the fixed plate driving device 19 contracts, pulling the material fixed plate 17 downward, so that the height of the fixed plate driving device 19 is less than the height of the conveyor belt 14. The piston rod of the positioning driving cylinder 11 extends, pushing the positioning rod 9 to rotate to a horizontal state. The conveyor belt 14 conveys the materials thereon towards the direction of the positioning rod 9 until they abut against the rotating wheel 12, completing the positioning of the materials. At this time, the piston rod of the fixed plate driving device 19 extends, pushing the material fixed plate 17 upward until the material fixing suction cup 18 on the material fixed plate 17 contacts the bottom of the material. The material fixing suction cup 18 adsorbs the material, realizing the fixation of the material. Since the material fixing device 16 and the material conveying device 8 in the present invention are both installed on the material fixing frame 4, the film on the unwinding device 2 passes through between the positioning roller and the pressing roller of the film path positioning device 7, and its end is adhered to the material. At this time, the film clamping device 20 releases the film and moves downward to disengage from the film. The material fixing frame 4 is driven by the driving motor 5 to rotate relative to the machine frame 1. Therefore, the material fixing device 16, the material conveying device 8, and the material adsorbed on the material fixed plate 16 by the material fixing suction cup 18 rotate synchronously with the material fixing frame 4. When the material fixing frame 4 rotates one week, a film can be wound around the material once, completing the film winding packaging of the material. At this time, the film clamping device 20 moves upward to clamp the film. The cutting driving device 25 of the film cutting device 6 drives the cutter 25 to move towards the material to cut the film, and then quickly retracts to the original position; the material fixing suction cup 18 releases the material and moves downward with the material fixed plate 17 to disengage from the material. At the same time, the piston rod of the positioning driving cylinder 11 contracts, pushing the positioning rod 9 to rotate, so that the positioning rod 9 no longer blocks the material. The conveyor belt 14 conveys the material from one end of the upper horizontal support plate 101 where the positioning rod 9 is located and sends it back to the flow packaging line to continue the subsequent processing; at this time, the next material enters the upper horizontal support plate 101 from the flow packaging line, repeating the above actions to continuously carry out the film winding packaging of the material.
