Description

Technical Field

[0001] This utility model relates to the technical field of flame-retardant film packaging equipment, specifically a flame-retardant film packaging equipment. Background Technology

[0002] Flame-retardant film packaging equipment is mainly used to treat flammable materials with flame retardants to ensure that the packaged goods have fire safety during transportation, storage and use.

[0003] For example, a protective film wrapping device with authorization announcement number "CN218317491U" achieves the limiting effect of clamps on hollow cylindrical products, thus reinforcing the products and effectively solving the problem of product displacement as the turntable rotates. The clamping method of clamps on the inner wall of the cylindrical product avoids damage caused by the product falling over during rotation, saving workers the work of repositioning fallen products, thereby improving the efficiency of wrapping cylindrical products. However, in the use of flame-retardant film packaging equipment, the film frame and the protective film are integrated, and other structures are connected to the left side of the film frame. When replacing the protective film, the entire film frame needs to be removed, which requires the coordinated operation of many operators and a long downtime of the flame-retardant film packaging equipment. This increases the difficulty of replacing the protective film of the film packaging equipment, resulting in a decrease in the packaging output of the film packaging equipment. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the difficulty of replacing the protective film of film packaging equipment is increased, which affects the packaging output of film packaging equipment, and a flame-retardant film packaging equipment is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution: Design a flame-retardant film packaging device, including a first outer shell and a second outer shell. The top left side of the first outer shell is fixedly connected to the bottom of the second outer shell. Screws are rotatably connected to both the upper and lower sides of the inner wall of the second outer shell. A block is threadedly connected to the outer wall of the screw. A control structure is connected to the right side of the block. A round rod is rotatably connected to the top right side of the first outer shell. A fixing structure is connected to the top of the round rod.

[0006] Preferably, the control structure includes a vertical plate and a top plate. The left side of the vertical plate is fixedly connected to the right side of the block, and the top of the vertical plate is fixedly connected to the bottom left side of the top plate. A first cylinder is fixedly connected to the inner wall of the top plate, and a first curved plate is fixedly connected to the output end of the first cylinder. A second curved plate is fixedly connected to the lower right side of the vertical plate, and a protruding rod is rotatably connected to the top of the second curved plate and the bottom of the first curved plate, respectively.

[0007] Preferably, the left-side protrusion of the first curved plate is slidably connected to the groove on the outer wall of the upright plate.

[0008] Preferably, the outer wall of the block is slidably connected to the right opening of the second outer shell.

[0009] Preferably, a first motor is fixedly connected to the top of the screw, a bracket is fixedly connected to the outer wall of the first motor, and the bottom of the bracket is fixedly connected to the top of the second housing.

[0010] Preferably, a second motor is fixedly connected to the bottom of the inner wall of the first housing.

[0011] Preferably, the output shaft of the second motor is fixedly connected to the bottom of the round rod.

[0012] Preferably, the fixing structure includes a square plate and a horizontal plate. The bottom of the square plate is fixedly connected to the top of the round rod, and the outer top of the square plate is fixedly connected to the bottom of a plurality of horizontal plates. A second cylinder is fixedly connected to the inner wall of the horizontal plate, and a clamping plate is fixedly connected to the output end of the second cylinder.

[0013] The flame-retardant film packaging equipment proposed in this utility model has the following advantages: By controlling the output end of the first cylinder in the structure to move the first curved plate upward, the protrusion at the bottom of the first curved plate disengages from the top of the flame-retardant film sleeve. Subsequently, the flame-retardant film sleeve is lifted upward and disengaged from the protrusion at the top of the second curved plate. Then, the bottom of the new flame-retardant film sleeve is inserted into the protrusion at the top of the second curved plate. Finally, the output end of the first cylinder moves the first curved plate downward, so that the protrusion at the bottom of the first curved plate is inserted into the top of the flame-retardant film sleeve, thus completing the replacement of the flame-retardant film sleeve. This eliminates the need to disassemble the entire flame-retardant film sleeve fixing structure, reducing the difficulty of replacing the protective film of the film packaging equipment and preventing the packaging output of the film packaging equipment from being affected.

[0016] The present invention will be further described below with reference to the accompanying drawings: Please see Figure 1-5 In this embodiment, a flame-retardant film packaging device includes a first outer shell 1 and a second outer shell 4. The top left side of the first outer shell 1 is fixedly connected to the bottom of the second outer shell 4. Screws 5 are rotatably connected to the upper and lower sides of the inner wall of the second outer shell 4. The upper and lower sides of the screws 5 are rotated by bearings in the circular openings on the upper and lower sides of the inner wall of the second outer shell 4 under force. A block 6 is threadedly connected to the outer wall of the screws 5. A control structure 2 is connected to the right side of the block 6. A round rod 10 is rotatably connected to the top right side of the first outer shell 1. The round rod 10 is rotated by bearings in the circular opening on the top right side of the first outer shell 1 under force. A fixing structure 3 is connected to the top of the round rod 10.

[0017] The control structure 2 includes a vertical plate 201 and a top plate 202. The left side of the vertical plate 201 is fixedly connected to the right side of the block 6, and the top of the vertical plate 201 is fixedly connected to the bottom left side of the top plate 202. A first cylinder 203 is fixedly connected to the inner wall of the top plate 202. The first cylinder 203 is a multi-stage cylinder with a self-locking function at the output end. A first curved plate 204 is fixedly connected to the output end of the first cylinder 203. A second curved plate 205 is fixedly connected to the lower right side of the vertical plate 201. The top of the second curved plate 205 and the bottom of the first curved plate 204 are respectively rotatably connected to protruding rods 206. The two protruding rods 206 are rotated by bearings in the top circular opening of the first curved plate 205 and the bottom circular opening of the first curved plate 204 respectively. The left protrusion of the first curved plate 204 is slidably connected to the groove on the outer wall of the vertical plate 201. By controlling the output end of the first cylinder 203 in structure 2 to move the first curved plate 204 upward, the protruding rod 206 at the bottom of the first curved plate 204 disengages from the top of the flame-retardant film sleeve. Then, the flame-retardant film sleeve is lifted upward and disengaged from the protruding rod 206 at the top of the second curved plate 205. Next, the bottom of the new flame-retardant film sleeve is inserted into the protruding rod 206 at the top of the second curved plate 205. Finally, the output end of the first cylinder 203 moves the first curved plate 204 downward, so that the protruding rod 206 at the bottom of the first curved plate 204 is inserted into the top of the flame-retardant film sleeve, thus completing the replacement of the flame-retardant film sleeve. This eliminates the need to disassemble the entire flame-retardant film sleeve fixing structure, reducing the difficulty of replacing the protective film of the film packaging equipment and preventing the packaging output of the film packaging equipment from being affected.

[0018] The outer wall of block 6 is slidably connected to the right opening of the second outer shell 4. Block 6 slides up and down through the right opening of the second outer shell 4 under force. The top of screw 5 is fixedly connected to the first motor 7, which is a servo motor. The outer wall of the first motor 7 is fixedly connected to the bracket 8. The bottom of the bracket 8 is fixedly connected to the top of the second outer shell 4. The bottom of the inner wall of the first outer shell 1 is fixedly connected to the second motor 9, which is a servo motor. The output shaft of the second motor 9 is fixedly connected to the bottom of the round rod 10.

[0019] The fixed structure 3 includes a square plate 301 and a horizontal plate 302. The bottom of the square plate 301 is fixedly connected to the top of the round rod 10. The top outer side of the square plate 301 is fixedly connected to the bottom of multiple horizontal plates 302. A second cylinder 303 is fixedly connected to the inner wall of the horizontal plate 302. The second cylinder 303 is a rechargeable multi-stage cylinder with a self-locking function at the output end. A clamping plate 304 is fixedly connected to the output end of the second cylinder 303.

[0020] Working principle: Flame-retardant film placement in flame-retardant film packaging equipment: The bottom of the flame-retardant film sleeve is inserted into the protrusion 206 on the top of the second curved plate 205. Then, the first cylinder 203 (the first cylinder 203 is a multi-stage cylinder with a self-locking function at the output end) is energized and its output end moves the first curved plate 204 downward, so that the protrusion 206 at the bottom of the first curved plate 204 is inserted into the top of the flame-retardant film sleeve, thus completing the installation of the flame-retardant film sleeve.

[0021] Flame-retardant film packaging equipment for securing packaging materials: The bottom of the package is attached to the top of the square plate 301. Then, the second cylinder 303 (the second cylinder 303 is a rechargeable multi-stage cylinder with a self-locking function at the output end, which is powered by an internal battery) is powered on and the output end moves the clamping plate 304 inward, so that the clamping plate 304 clamps the outer wall of the package. Multiple second cylinders 303 can be operated separately to meet the needs of fixing packages of different sizes.

[0022] Flame-retardant film packaging equipment operation: First, pull the flame-retardant film on the outer wall of the flame-retardant film sleeve to the right, so that the end of the flame-retardant film stands on the outer wall of the package through the tape. At this time, the second motor 9 (located on the inner wall of the first outer shell 1, with an inspection port at the rear of the first outer shell 1 to see the operation of the second motor 9 and facilitate maintenance) is powered on. The output shaft of the second motor 9 (a servo motor that can control the rotation speed of the output shaft) rotates the square plate 301. The rotating square plate 301 causes the package fixed at the top to rotate, thereby pulling the flame-retardant film and causing it to wrap around the outer wall of the package. At this time, the first motor 7 (a servo motor that can control the rotation speed and direction of the output shaft) is powered on, and its output shaft rotates the screw 5. The rotating screw 5 causes the square block 6 to move upward, which in turn, in conjunction with the control structure 2, moves the flame-retardant film sleeve upward, thereby causing the flame-retardant film to wrap around the outer wall of the package. The outer wall is gradually wrapped upwards. Then, the two motors stop working. The output end of the second cylinder 303 moves outwards with the clamping plate 304 to detach from the packaging. Then, the upper and lower positions of the packaging are reversed. Next, the output end of the second cylinder 303 moves inwards with the clamping plate 304, so that the clamping plate 304 presses against the outer wall of the packaging. Then, the end of the flame-retardant film is adhered to the outer wall of the packaging. Then, the two motors are powered on and the output shaft of the first motor 7 rotates in the opposite direction. At this time, the screw 5 rotates in the opposite direction and moves the block 6 downwards, cooperating with the control structure 2 to move the flame-retardant film sleeve downwards, so that the flame-retardant film wraps around the outer wall of the packaging from top to bottom. Then, the above operation is repeated to swap the other unwrapped parts of the packaging and wrap the flame-retardant film. After all sides of the packaging are wrapped with flame-retardant film, the output end of the second cylinder 303 moves outwards with the clamping plate 304 to detach from the packaging. Then, the packaging is moved away from the top of the square plate 301.

[0023] Replacement of flame-retardant film sleeves in flame-retardant film packaging equipment: When the flame-retardant film on the outer wall of the flame-retardant film sleeve is exhausted, the output end of the first cylinder 203 moves the first curved plate 204 upward, causing the protruding rod 206 at the bottom of the first curved plate 204 to disengage from the top of the flame-retardant film sleeve. Then, the flame-retardant film sleeve is lifted upward, disengaging from the protruding rod 206 at the top of the second curved plate 205. Next, the bottom of a new flame-retardant film sleeve is inserted into the protruding rod 206 at the top of the second curved plate 205. Finally, the output end of the first cylinder 203 moves the first curved plate 204 downward, causing the protruding rod 206 at the bottom of the first curved plate 204 to insert into the top of the flame-retardant film sleeve, completing the replacement of the flame-retardant film sleeve without disassembling the entire flame-retardant film sleeve fixing structure. Although this utility model has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
