Description

Technical Field

[0001] This utility model belongs to the field of packaging machines, specifically relating to a through-type bidirectional packaging head machine. Background Technology

[0002] For long, rod-shaped items, such as aluminum profiles and PVC pipe bundles, the ends of the rods are usually wrapped to prevent them from being damaged by bumps during transportation and to avoid the sharp edges of the rods cutting other items, thus improving transportation safety.

[0003] The current method involves using a baling machine to output the film cloth downwards, inserting the end of the rod into the baling machine and pushing the film cloth forward. The film cloth bends as the rod moves, and then the tape wrapping device of the baling machine wraps around the end of the rod. The tape is then cut with the help of a blade, so that the film cloth tightly wraps the end of the rod, completing the wrapping operation at one end of the rod.

[0004] However, if the membrane is pushed directly by the end of the rod, the membrane is prone to shifting or uneven bending angle, excessive wrinkling, and severe local accumulation of the membrane on the rod, resulting in partial exposure of the rod end and making it difficult to guarantee the wrapping effect. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the present invention provides a through-type bidirectional wrapping machine, which can improve the uniformity of wrapping the membrane on the rod and prevent the front and rear ends of the membrane from being open, thus exposing the side walls of the rod ends.

[0006] The specific technical solution adopted in this utility model is as follows:

[0007] The through-type bidirectional wrapping machine includes a frame, a film coating mechanism mounted on the frame, and a tape winding device. The key feature is that the film coating mechanism includes a film roll, a film output roller pair, a conveyor roller, and an arc-shaped chuck. The arc-shaped chuck is arranged sequentially around its own circumference. The conveyor roller, arc-shaped chuck, and tape winding device are arranged sequentially along the axial direction of the rod. The conveyor roller and arc-shaped chuck are both located below the film output roller pair. The film roll outputs the film fabric between the conveyor roller and the arc-shaped chuck via the film output roller pair. The rod has the freedom to pass sequentially through the arc-shaped chuck and the tape winding device via the conveyor roller.

[0008] The frame is equipped with two sets of film coating mechanisms, which are arranged sequentially along the axial direction of the rod. The tape winding device is located between the arc-shaped chucks of the two sets of film coating mechanisms.

[0009] The inner wall of the arc-shaped chuck is provided with flexible arc-shaped fan blades, and the overhanging end of the flexible arc-shaped fan blades forms a set of teeth spaced around the circumference of the arc-shaped chuck by means of a notch.

[0010] The coating mechanism further includes a guide groove arranged in a vertical direction, which is located at one end of the membrane fabric and limits the end of the membrane fabric.

[0011] The film exit rollers include a power roller and an auxiliary roller arranged in parallel. The power roller is driven and connected to a first motor and has the degree of freedom to rotate around its own axis on the frame. The auxiliary roller is connected to the telescopic end of a first telescopic cylinder and has the degree of freedom to reciprocate toward the power roller on the frame by means of the first telescopic cylinder.

[0012] The film coating mechanism further includes a film cutting device, which includes a conveyor belt and a cutter mounted on the horizontal surface of the conveyor belt. The conveying direction of the conveyor belt is parallel to the axial direction of the film exit rollers. The film exit rollers and the conveyor belt are arranged sequentially along the output direction of the film. The cutter is perpendicular to the film and extends from the conveyor belt toward the film.

[0013] The beneficial effects of this utility model are:

[0014] This invention adds an arc-shaped chuck to the wrapping machine. The end of the rod pushes the membrane cloth through the arc-shaped chuck, and the arc-shaped chuck cooperates to form a circumferential constraint on the membrane cloth, preventing the membrane cloth from shifting and forcing the membrane cloth to adhere to the outer wall of the rod, thereby improving the uniformity of the membrane cloth wrapping on the rod. In particular, the front and rear ends of the membrane cloth are constrained so that the front and rear ends of the membrane cloth wrap around the sides of the rod, preventing the front and rear ends of the membrane cloth from being open and causing the side walls of the rod ends to be exposed, thus ensuring the quality of the wrapping.

[0015] The frame is equipped with two sets of film coating mechanisms, which are arranged sequentially along the axial direction of the rod. The rod can be moved back and forth to achieve the wrapping operation at both ends. When the rod is performing the wrapping operation at the second end, the next rod can be placed on the conveyor roller of the idle film coating mechanism to wait for the film to be produced and wrapped by the tape winding device, which effectively shortens the waiting time at the work station and improves the work efficiency of the wrapping operation.

[0016] The inner wall of the arc-shaped chuck is equipped with flexible arc-shaped fan blades. The overhanging ends of the flexible arc-shaped fan blades form a set of teeth spaced around the circumference of the arc-shaped chuck through the notch. When the rod passes through the arc-shaped chuck, the teeth are folded outward by the force of the membrane cloth, which flexibly restrains the membrane cloth. It can also meet the head wrapping operation of rods with different diameters, increasing the versatility of the through-type bidirectional head wrapping machine. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] Specific implementation examples Figure 1 As shown, this utility model relates to a through-type bidirectional wrapping machine, including a frame 1, a film coating mechanism and a tape winding device 9 mounted on the frame 1. The tape winding device 9 is prior art. Crucially, the film coating mechanism includes a film roll 2, film output rollers 3, a conveying roller 4, and an arc-shaped chuck 5. Figure 3 As shown, the arc-shaped chucks 5 are arranged sequentially around the circumference of their respective circles. In this embodiment, two mirror-image arc-shaped chucks 5 are arranged on the frame 1, with a gap between them and located on the left and right sides of the rod 6. The gap between the two arc-shaped chucks 5 is vertical, and the sum of the central angles subtended by each arc-shaped chuck 5 is greater than 180°. In this embodiment, it is preferable that the central angle subtended by each arc-shaped chuck 5 is 120°, that is, the sum of the central angles subtended by each arc-shaped chuck 5 is 240°. The conveyor roller 4, the arc-shaped chucks 5, and the tape winding device 9 are arranged sequentially along the axial direction of the rod 6, as follows. Figure 2 As shown, the conveyor roller 4 and the arc-shaped chuck 5 are both located below the film output roller 3 and the film roll 2. The film roll 2 outputs the film cloth between the conveyor roller 4 and the arc-shaped chuck 5 with the help of the film output roller 3. The rod 6 has the freedom to pass through the arc-shaped chuck 5 and the tape winding device 9 in sequence with the help of the conveyor roller 4.

[0024] This invention incorporates an arc-shaped chuck 5. During operation, the membrane fabric is driven downwards from the membrane roll 2 by the output roller 3, entering between the conveying roller 4 and the arc-shaped chuck 5. A rod 6 is placed on the conveying roller 4 and moves towards the arc-shaped chuck 5. During this movement, the end of the rod 6 contacts the membrane fabric first. As the rod 6 continues to move, the end pushes the membrane fabric through the arc-shaped chuck 5. The arc-shaped chuck 5, in conjunction with the membrane fabric, forms a surrounding constraint, preventing the membrane fabric from shifting and forcing it to adhere to the outer wall of the rod 6, thus improving the uniformity of the membrane fabric wrapping around the rod 6. In particular, the front and rear ends of the membrane fabric are constrained, ensuring they wrap around both sides of the rod 6, preventing the front and rear ends from being open and exposing the side walls of the rod 6. Figure 3The left and right direction settings.

[0025] The gap between the two arc-shaped chucks 5 provides space for the membrane cloth to bend and be extrude in the upper and lower positions. While ensuring effective constraint on the membrane cloth, it can also avoid excessive interference with the membrane cloth, allowing the membrane cloth to move smoothly with the rod 6 and reducing the risk of jamming.

[0026] Preferably, the frame 1 is provided with two sets of coating mechanisms, which are arranged sequentially along the axial direction of the rod 6. Figure 2 The central member is axially oriented left and right, and the tape winding device 9 is positioned between the arc-shaped chucks 5 of the two laminating mechanisms. The member 6 moves from right to left through the right laminating mechanism and then through the tape winding device 9. Tape is output from the tape winding device 9 and wound around the member 6, binding the film to the member 6. The tape is then cut, completing the wrapping operation at the left end of the member 6. The member 6 continues to move from right to left, and its right end moves to the left laminating mechanism. After the film is output from the left laminating mechanism, the member 6 moves back from left to right. The right end of the member 6 pushes the film through the arc-shaped chuck 5 of the left laminating mechanism, and the tape winding device 9 wraps the film on the right end of the member 6. The tape is then cut, completing the wrapping operation at both ends of the member 6.

[0027] When the rod 6 is performing the wrapping operation on the right end, the next rod 6 can be placed on the conveyor roller 4 of the right-side film coating mechanism and wait to be wrapped by the tape wrapping device 9, which effectively shortens the waiting time at the work station and improves the work efficiency of the wrapping operation.

[0028] Preferred, such as Figure 3 As shown, a flexible arc-shaped fan blade 501 is provided on the inner wall of the arc-shaped chuck 5. The overhanging end of the flexible arc-shaped fan blade 501 forms a set of teeth spaced around the circumference of the arc-shaped chuck 5 by means of a notch. In this embodiment, the flexible arc-shaped fan blade 501 is made of rubber. When the rod 6 passes through the arc-shaped chuck 5, the teeth are folded outward by the force of the membrane cloth, which flexibly constrains the membrane cloth. It can also meet the head wrapping operation of rods 6 with different diameters, increasing the versatility of the through-type bidirectional head wrapping machine.

[0029] like Figure 2 As shown, the coating mechanism also includes a guide groove 7 arranged vertically. The guide groove 7 is located at one end of the film cloth and limits that end of the film cloth. Specifically, two round rods are installed in pairs on the frame 1. The two round rods are arranged vertically, and the gap between the round rods forms the guide groove 7. The guide groove 7 is located directly below the output end of the film exit roller 3. During the falling process of the film cloth, one end of the film cloth enters the guide groove 7, which limits the film cloth and ensures that the film cloth can accurately cover the end of the rod 6.

[0030] like Figure 4As shown, the film output roller 3 includes a power roller 301 and an auxiliary roller 302 arranged in parallel. The power roller 301 is driven and connected to a first motor and has the freedom to rotate around its own axis on the frame 1. The auxiliary roller 302 is connected to the telescopic end of a first telescopic cylinder and has the freedom to move back and forth on the frame 1 towards the power roller 301 by means of the first telescopic cylinder. This allows the distance between the power roller 301 and the auxiliary roller 302 to be adjusted to accommodate film fabrics of different thicknesses. It also helps to ensure uniform tension of the output film fabric, so that the film fabric can be output flat.

[0031] The film-coating mechanism also includes a film-cutting device, which includes a conveyor belt 8 and a cutter mounted on the horizontal surface of the conveyor belt 8. The conveying direction of the conveyor belt 8 is parallel to the axial direction of the film output rollers 3. The film output rollers 3 and the conveyor belt 8 are arranged sequentially along the output direction of the film. The cutter is perpendicular to the film and extends from the conveyor belt 8 toward the film. The conveyor belt 8 drives the cutter to move, so that the cutter cuts the film, realizing the automatic separation of the film on the film roll 2 from the rod 6, thereby realizing automatic and continuous packaging and unloading operations.
