Description

Technical Field

[0001] The utility model belongs to the technical field of wrapping packaging machines, and in particular relates to a horizontal wrapping packaging machine for reel-type products. Background Art

[0002] Reel products are a type of product that is formed into a ring structure by coiling plastic materials, such as air-conditioning copper tubes. However, this type of product is more likely to deform when bumped, so it needs to be wrapped with a layer of wrapping film and a layer of bubble film before sales and transportation. The wrapping film plays a role in fixing and moisture-proofing, while the bubble film plays a role in buffering and preventing bumps, thereby avoiding deformation and other problems of this type of product.

[0003] At present, horizontal wrapping machines are usually used to wrap wrapping film and bubble film on reel products. However, the current wrapping machines can only wrap one film at a time and cannot wrap two films at the same time. Therefore, two wrapping machines are required on each production line to wrap the wrapping film and bubble film respectively, which increases equipment investment and floor space. Utility Model Content

[0004] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a horizontal wrapping packaging machine for reel-type products. By adding a second material storage roller for winding the wrapping film and a pneumatic clamp for clamping the end of the wrapping film, the wrapping film and the bubble film can be wound simultaneously, which not only saves equipment investment and floor space, but also improves the winding efficiency.

[0005] The specific technical solution adopted by the utility model is:

[0007] A pre-tightening belt is also arranged above the rotating disk, and the pre-tightening belt matches the winding roller and presses the bubble film on the surface of the winding roller.

[0008] The frame is respectively provided with a first guide roller and a second guide roller at both ends of the turntable, a fixed hanger fixedly connected to the frame is provided above the first guide roller, a pre-tensioning hanger connected to the frame by a spring is suspended above the second guide roller, both ends of the pre-tensioning belt are respectively fixedly connected to the fixed hanger and the pre-tensioning hanger, and the pre-tensioning belt passes under the first guide roller, above the turntable, and under the second guide roller in sequence.

[0009] The distance between the second material storage roller and the center of the turntable is smaller than the distance between the winding roller and the center of the turntable.

[0010] The frame is also provided with a mechanical clamp, which has the freedom to move back and forth along the feeding direction and the film feeding direction. The end of the bubble film on the first storage roller is moved to between the center of the turntable and the winding roller with the help of the mechanical clamp, and the bubble film is wound around the winding roller and then wound onto the reel-type product with the help of the rotation of the turntable.

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0023] Specific embodiments, such as Figure 1-5 As shown, the utility model provides a horizontal wrapping packaging machine for reel-type products, including a frame 1, on which a feeding mechanism, a rotating mechanism, and a winding mechanism are arranged, the winding mechanism includes a C-shaped turntable 2, a first material storage roller 3, and a power unit for driving the turntable 2 to rotate, and a side wall of one side of the turntable 2 is provided with a plurality of winding rollers 4 in a ring array, the bubble film on the first material storage roller 3 is wound around the winding roller 4 and onto the reel-type product with the help of the rotation of the turntable 2, the winding mechanism also includes a second material storage roller 5 wrapped with a wrapping film and a pneumatic clamp 6, the second material storage roller 5 is arranged on the side wall of the turntable 2 on the same side as the winding roller 4, the pneumatic clamp 6 has the freedom to extend and retract along the feeding direction, and the extension and retraction direction of the pneumatic clamp 6 passes through the winding path of the wrapping film, and the wrapping film is wound onto the reel-type product with the help of the clamping of the pneumatic clamp 6 and the rotation of the turntable 2.

[0024] At present, horizontal wrapping machines are usually used to wrap wrapping film and bubble film on reel products. However, the current wrapping machines can only wrap one film at a time and cannot wrap two films at the same time. Therefore, two wrapping machines are required on each production line to wrap the wrapping film and bubble film respectively, which increases equipment investment and floor space.

[0025] Therefore, the utility model adds a second storage roller 5 for winding the wrapping film on the turntable 2 of the wrapping mechanism, so as to realize the simultaneous wrapping of the wrapping film and the bubble film. Taking the air-conditioning copper tube as an example, during packaging, the feeding mechanism conveys the air-conditioning copper tube to the wrapping mechanism, and the reel of the air-conditioning copper tube is fed into the rotation range of the turntable 2 by means of the C-shaped notch of the turntable 2, so that the turntable 2 bypasses the center of the reel when rotating, and then the mechanical gripper 12 clamps the end of the bubble film, and the mechanical gripper 12 moves along the C-shaped notch of the turntable 2. Figure 2 The left direction, that is, the negative direction of the X axis, extends out, such as Figure 2 As shown in the figure, the bubble film is pulled through the winding roller 4 and enters the inner ring side of the turntable 2. As the turntable 2 rotates, the bubble film is wound around the outer surface of the winding roller 4 onto the turntable 2. Figure 4-5 As shown, B is a cross-sectional schematic diagram of the reel. When the turntable 2 rotates, after the strip-shaped bubble film is picked up by the winding roller 4, the mechanical clamp 12 moves along Figure 2 The lower side direction, that is, the negative direction of the Y axis, is withdrawn to prevent the second circle of bubble film from being placed on the mechanical clamp 12 again. When the second circle of bubble film is wound on the reel, the first circle of the bubble film is pressed and fixed by the second circle, and the mechanical clamp 12 is released. Then, the turntable 2 is used to rotate around the air-conditioning copper tube to be wound on the air-conditioning copper tube. At the same time, the second storage roller 5 also rotates with the turntable 2. Since the wrapping film on the second storage roller 5 is clamped and fixed by the pneumatic clamp 6, the second storage roller 5 rotates around the air-conditioning copper tube so that the wrapping film can be tightly wound on the air-conditioning copper tube. When the ends of the bubble film and the wrapping film are wrapped around the air-conditioning copper tube for several circles and fixed, the mechanical clamp 12 and the pneumatic clamp 6 release the bubble film and the wrapping film. At this time, the rotating mechanism is started to drive the air-conditioning copper tube to rotate in place, and the ring winding mechanism is used to make the bubble film and the wrapping film evenly ring-wound on the air-conditioning copper tube. Through the above structure and working process, the wrapping film and the bubble film can be wound at the same time, which not only saves equipment investment and floor space, but also improves the winding efficiency.

[0026] The power unit in the utility model includes a plurality of driving wheels 20 arranged in a circular array along the circumference of the turntable 2. The edges of the driving wheels 20 cooperate with the edges of the turntable 2. The turntable 2 rotates by means of the friction between the driving wheels 20 and the turntable 2.

[0027] In addition, an electric hot cutter is provided between the turntable 2 and the first stock roller 3. In the process of the bubble film being wound onto the turntable 2, when the bubble film is wound to a length sufficient for winding the air-conditioning copper tube, the electric hot cutter cuts the bubble film. After the bubble film has finished winding the air-conditioning copper tube and the rotating mechanism stops, the wrapping film continues to wrap there and wrap the end of the bubble film, and the bubble film is fixed by means of the viscosity of the wrapping film, thereby preventing the end of the bubble film from warping up and other loose wrapping conditions.

[0028] like Figure 1-2As shown, a pre-tensioning belt 7 is also provided above the turntable 2, and the pre-tensioning belt 7 matches with the winding roller 4 and presses the bubble film on the surface of the winding roller 4. Since the bubble film is firstly wound onto the turntable 2 by the first storage roller 3 with the aid of the winding roller 4, the bubble film may not be tightly wound during the process of winding onto the turntable 2, which will cause the bubble film to be loosely wound when subsequently wound onto the air-conditioning copper tube. Therefore, the pre-tensioning belt 7 is provided to press the bubble film on the surface of the winding roller 4, thereby ensuring the tight winding between the bubble film and the turntable 2, and further ensuring the winding effect of the bubble film on the surface of the air-conditioning copper tube.

[0029] like Figure 1-2 As shown, the frame 1 is respectively provided with a first guide roller 8 and a second guide roller 9 at both ends of the turntable 2, a fixed hanger 10 fixedly connected to the frame 1 is provided above the first guide roller 8, and a pre-tensioning hanger 11 connected to the frame 1 by means of a spring is suspended above the second guide roller 9, and both ends of the pre-tensioning belt 7 are respectively fixedly connected to the fixed hanger 10 and the pre-tensioning hanger 11, and the pre-tensioning belt 7 passes under the first guide roller 8, above the turntable 2 and under the second guide roller 9 in sequence. In order to avoid the pre-tensioning belt 7 being pressed too tightly and causing the bubble film to be dislocated or damaged, the utility model is also provided with a fixed hanger 10 and a pre-tensioning hanger 11, wherein the pre-tensioning hanger 11 is fixed by means of a spring, and can self-adjust the tightness of the pre-tensioning belt 7 in real time, so that the pre-tensioning belt 7 and the bubble film on the surface of the winding roller 4 are always at an appropriate pressure.

[0030] like Figure 1 As shown, the distance between the second stock roller 5 and the center of the turntable 2 is smaller than the distance between the winding roller 4 and the center of the turntable 2. Since the pre-tensioning belt 7 needs to press the winding roller 4, the winding roller 4 is arranged on the outer side of the turntable 2 and the second stock roller 5 is arranged on the inner side of the turntable 2.

[0031] like Figure 1 As shown, the frame 1 is also provided with a mechanical clamp 12, and the mechanical clamp 12 has the freedom to move back and forth along the feeding direction and the film feeding direction. The end of the bubble film on the first storage roller 3 is moved to between the center of the turntable 2 and the winding roller 4 with the help of the mechanical clamp 12, and the bubble film is wound around the winding roller 4 and then wound onto the reel-type product with the help of the rotation of the turntable 2. At the beginning of the bubble film winding, the head end of the bubble film needs to be clamped with the help of the mechanical clamp 12 to ensure that the bubble film can be wound onto the turntable 2 and the air-conditioning copper tube. After the bubble film is wound for several turns, the head end of the bubble film is wound and fixed, so it does not need to be clamped, and the mechanical clamp 12 is reset to wait for the next group of air-conditioning copper tubes to be wound.

[0032] like Figure 1As shown, the feeding mechanism includes two groups of feeding rollers 13 and a driving unit for driving the two groups of feeding rollers 13 to rotate, and a gap is formed between the two groups of feeding rollers 13 for the turntable 2 to pass through. Since the turntable 2 needs to pass through the central area of ​​the air-conditioning copper tube and form a surround, a gap needs to be left for the turntable 2 to pass through, wherein the frame 1 on both sides of the feeding roller 13 is provided with a transmission belt driven by a motor 19, and the transmission belt is matched with the axis of the feeding roller 13 to make multiple feeding rollers 13 rotate simultaneously, and the transmission belt forms a driving unit of the feeding roller 13.

[0033] like Figure 1-2 As shown, the rotating mechanism includes a fixed frame 14, a limiting roller 15 fixedly connected to the fixed frame 14, and a rotating roller 16 hinged to the fixed frame 14. The limiting roller 15 is provided in multiple numbers and is distributed in a herringbone shape matching the reel-type products. The rotating roller 16 is connected to the output end of the motor 19 at one end away from the fixed frame 14 and rotates. A telescopic cylinder 17 is also provided below the fixed frame 14. The telescopic end of the telescopic cylinder 17 is fixedly connected to the fixed frame 14. The rotating mechanism is lowered to the fixed frame 14 by means of the telescopic cylinder 17. Below the upper surface of the feeding mechanism, the rotating mechanism is located below the upper surface of the feeding roller 13 before the air-conditioning copper tube is fed. When the air-conditioning copper tube is transported to the winding mechanism, the rotating mechanism is lifted by the telescopic cylinder 17. Three rotating rollers 16 are provided and distributed in a herringbone shape. The rotating rollers 16 lift the air-conditioning copper tube and drive the air-conditioning copper tube to rotate with the help of friction. At this time, the three limiting rollers 15 distributed in a herringbone shape are located in the inner ring of the air-conditioning copper tube and fit with the inner side of the ring wall of the air-conditioning copper tube to ensure that the air-conditioning copper tube can rotate in place to ensure the winding effect.

[0034] like Figure 3 As shown, a heating module 18 is arranged under the pneumatic clamp 6, and the wrapping film between the second stock roller 5 and the reel-type product is melted with the help of the heating module 18. When the wrapping film is finished, the pneumatic clamp 6 clamps the wrapping film, and melts the wrapping film between the pneumatic clamp 6 and the end of the air-conditioning copper tube winding with the help of the heating module 18. After the melting, the air-conditioning copper tube that has been wound is discharged with the help of the feeding roller 13, and the pneumatic clamp 6 continues to clamp the end of the wrapping film on the second stock roller 5 and waits for the next group of air-conditioning copper tubes to be wound, wherein the heating module 18 is an electric heating wire or an electric heating cutter.
