Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a top laminating machine. Background Art

[0002] Some large products need to be laminated before packaging and transportation to improve moisture-proof and dust-proof effects and provide better protection for the products. Since the top cannot be affected when wrapping the sides, the top needs to be laminated separately. Therefore, two steps are required for laminating: first laminate the top and then wrap the sides.

[0003] At present, when performing top lamination, some people use manual lamination, cutting a section of film to cover the top of the product, and some people use a machine to clamp a section of the cut film and then lay it on the top of the product. Due to the low work efficiency, a top laminating machine is designed. The existing top laminating machine automatically conveys the film, and the product moves under the film, so that the film automatically covers the product, and then the film is cut off to achieve top lamination. However, in actual use, the film is easy to slip off the product, affecting the normal operation of the lamination, and the product can only move slowly during the conveying process, which is responsible for the greater chance of the film falling off.

[0032] Example:

[0033] Reference Figure 1-Figure 5 As shown, a top laminating machine comprises a base 1, a support assembly 2 is provided on the base 1, a lifting assembly 4, a positioning assembly 3 for positioning a roll film 303, a film pulling assembly 5 for spreading the film, and a film cutting assembly 6 for cutting the film are provided on the support assembly 2;

[0034] The film-pulling assembly 5 includes an auxiliary bracket 5010, a connecting beam 502 is horizontally arranged on the bracket assembly 2, the auxiliary bracket 5010 is arranged on the connecting beam 502, and a film-pulling cylinder 503 is also arranged between the auxiliary bracket 5010 and the bracket assembly 2. A movable bracket 501 is arranged on the film-pulling cylinder 503, and two sets of movable film clamps are symmetrically arranged on the movable bracket 501. A fixed film clamp is arranged at the position corresponding to the movable film clamp on the auxiliary bracket 5010;

[0035] The film cutting assembly 6 includes a film cutting cylinder 601, which is arranged on the movable frame 501 and located between the movable film clamp and the fixed film clamp. A film cutting blade 602 is arranged on the film cutting cylinder 601, and the moving direction of the film cutting blade 602 is perpendicular to the moving direction of the movable film clamp.

[0036] The lifting assembly 4 is used to drive the film pulling assembly 5 and the film cutting assembly 6 to rise and fall, so that the film can be laid on the top of the product.

[0037] The positioning assembly 3 is used to fix the film cylinder to ensure that the film cylinder can transport the film to the film pulling assembly 5.

[0038] After the movable film clamp of the film-pulling assembly 5 holds the end of the film, it moves to the position of the fixed film clamp together with the film-pulling cylinder 503. After the fixed film clamp clamps the end of the film, the movable film clamp follows the cylinder back to the initial position and clamps the film.

[0039] The cutting blade moves with the cutting cylinder. During the movement, the film cutting blade 602 cuts off the film clamped by the movable film clamp and the fixed film clamp from the movable film clamp, so that the film can stay on the top of the product.

[0040] Assemble the film cylinder onto the positioning assembly 3, guide the end of the film to the movable film clamp, clamp the end of the film with the movable film clamp, then start the film pulling cylinder 503, so that the movable film clamp pulls the film to move to the fixed film clamp, and the fixed film clamp clamps the end of the film, start the film pulling cylinder 503 again, so that the movable film clamp moves to the initial position and clamps the film, then start the lifting cylinder 401, lay the film on the top of the product, then start the film cutting cylinder 601, so that the film cutting blade 602 cuts the film from the movable film clamp, and then releases the fixed film clamp, and the cut film can stay on the top of the product.

[0041] The support assembly 2 includes two support columns 201 and a top beam 202 disposed between the two support columns 201 . The top beam 202 is located at the top of the support columns 201 .

[0042] The bracket assembly 2 is the supporting structure of the entire equipment, which is convenient for installing the lifting assembly 4, the film pulling assembly 5, the positioning assembly 3 and the film cutting assembly 6.

[0043] The lifting assembly includes a lifting cylinder 401, a lifting guide rail 403 and a lifting plate 402. There are two lifting guide rails 403, which are respectively arranged on two support columns 201 and are located on the same side. A slot matching the lifting guide rail 403 is opened on the lifting plate 402. The lifting plate 402 slides along the lifting guide rail 403. The lifting cylinder 401 is fixed on the top beam 202, and the output shaft of the lifting cylinder 401 is connected to the lifting plate 402.

[0044] The output shaft of the lifting cylinder 401 moves up and down, driving the lifting plate 402 to slide along the lifting track, thereby driving the components installed on the lifting plate 402 to move up and down. The lifting component 4 is used to lay the film on the top of the product.

[0045] The positioning assembly 3 includes two positioning brackets 301 . The two positioning brackets 301 are respectively arranged on two supporting columns 201 . A positioning shaft 302 is arranged between the two positioning brackets 301 . A tubular film 303 is sleeved on the positioning shaft 302 .

[0046] The positioning shaft 302 is arranged between two support frames, and the tubular film 303 can be arranged on the positioning shaft 302 . The tubular film 303 can rotate on the positioning shaft 302 . When the film is pulled out from the tubular film 303 , the tubular film 303 rotates to pull the film out.

[0047] The guide assembly 7 is also included. The guide assembly 7 includes two guide brackets 701 . The two guide brackets 701 are symmetrically arranged on the lifting plate 402 . Guide rollers 702 are rotatably arranged on the guide brackets 701 .

[0048] The guide roller 702 of the wire assembly guides the film to the movable film clamp on the one hand, and on the other hand ensures the flatness of the film and prevents the film from curling, thereby reducing the dust and moisture proof effect and failing to effectively protect the product.

[0049] like Figure 5 As shown, the fixed film clamp includes a first clamping cylinder 504, the output end of the first clamping cylinder 504 is fixed with a first connecting block 506, the first connecting block 506 is rotatably provided with a first clamping assembly 505, the first clamping assembly 505 includes two first clamping units, the first clamping unit includes a "concave" shape, one end of the first clamping unit is hinged to the output shaft of the first clamping cylinder 504, the other end is provided with a chuck, and the bottom is hinged to the first connecting block 506 near the first clamping cylinder 504, and the openings of the two first clamping units are arranged opposite to each other.

[0050] The first clamping cylinder 504 is extended and retracted to drive the end of the first clamping unit to move, and the first clamping unit is hinged to the first connecting block 506, so that the first clamping unit rotates on the first connecting block 506, and the other end of the first clamping unit rotates at the same time, thereby driving the clamping head to rotate together. The two first clamping units are arranged opposite to each other. When the first clamping units rotate, the two clamping heads move closer or apart, forming a clamping or loosening operation on the membrane.

[0051] like Figure 5 As shown, the movable membrane clamp includes a second clamping cylinder 507, a second connecting block 508 is fixed to the output end of the second clamping cylinder 507, a second clamping assembly 509 is rotatably arranged on the second connecting block 508, and the second clamping assembly 509 includes two second clamping units, the second clamping unit includes a "concave" shape, one end of the second clamping unit is hinged to the output shaft of the second clamping cylinder 507, and a clamping plate is arranged at the other end, and the bottom is hinged to the second connecting block 508 near the second clamping cylinder 507, the two second clamping unit openings are arranged opposite to each other, and a clearance groove 5011 is opened on the clamping plate at the position corresponding to the clamping head.

[0052] The clamping and releasing operation of the film is the same as that of the fixed film clamp. A clearance groove 5011 corresponding to the clamp head of the fixed film clamp is set on the clamp plate of the movable film clamp. After the movable film clamp moves to the fixed film clamp with the film pulling cylinder 503, the fixed film clamp needs to clamp the film. The clamp head is inserted into the clearance groove 5011. The film is clamped in the clamp plate, and part of the film will leak out at the clearance groove 5011, and the clamp head can clamp the part of the film. The clearance groove 5011 is used to facilitate the clamp head to clamp the film on the one hand, and to prevent the clamp head from colliding with the clamp plate, which affects the stability of the film clamping.

[0053] The positioning assembly 3 also includes a positioning sleeve 304, which is arranged on the positioning shaft 302 and located on both sides of the tube membrane 303. One end of the positioning sleeve 304 abuts against the end of the tube membrane 303, and the other end abuts against the positioning bracket 301; one end of the positioning shaft 302 passes through the positioning bracket 301, and the end is threadedly connected with a locking nut.

[0054] The positioning sleeve 304 is arranged on the positioning shaft 302 to fix the position of the tube film 303 on the positioning shaft 302, so as to prevent the tube film 303 from shaking on the positioning shaft 302 during the rotation process, thereby ensuring the stability of the film output, and then ensuring the flatness of the film, and ensuring the protection of the product. A locking nut is arranged at the end of the positioning seat to facilitate the positioning shaft 302, and then facilitate the loading and unloading of the tube film 303 from the positioning shaft 302.

[0055] The base 1 is provided with a mounting ear plate 101 , and the mounting ear plate 101 is provided with a mounting hole 102 .

[0056] A mounting ear plate 101 with a mounting hole 102 is provided on the bottom plate, and the mounting ear plate 101 is fixed by means of the mounting hole 102 in cooperation with the anchor bolts, thereby fixing the base 1, thereby ensuring the stability of the position of the equipment and preventing the position of the equipment from changing during operation, thereby affecting the coverage of the membrane on the product and the protective effect of the product, while avoiding the collapse of the equipment and improving the safety of use.

[0057] A pressing plate is also provided on the movable frame 501 . The pressing plate is located on a side of the film-pulling cylinder 503 close to the lifting plate 402 , and the horizontal position of the pressing plate is lower than that of the film-pulling cylinder 503 .

[0058] When the fixed film clamp clamps the end of the film, the movable film clamp returns to the initial position, and the copper drum pressure plate flattens the film to ensure that the film can fully cover the product and ensure the protection effect of the product.

[0059] Fix the equipment to the ground by installing the ear plate 101 in conjunction with the anchor bolts. First, loosen the locking nut, remove one end of the positioning shaft 302 from the positioning bracket 301, then install the tube film 303 on the positioning shaft 302, and then tighten it with the positioning sleeve 304. Then, clamp the positioning shaft 302 on the positioning bracket 301 and fix the positioning shaft 302 with the locking nut.

[0060] Before use, the worker first pulls the end of the membrane to the movable membrane clamp and clamps the end of the membrane with a clamp.

[0061] When in use, when the product moves to the bottom of the connecting beam 502, the product stays at this position, and then the film-pulling cylinder 503 is started to drive the movable film clamp to move to the fixed film clamp, and the clamp of the fixed film clamp is inserted into the yield groove 5011 of the clamp of the movable film clamp, and then the first clamping cylinder 504 is started to make the clamp clamp the end of the film, and then the second clamping cylinder 507 is started to make the clamp release the film, and the film-pulling cylinder 503 is started again to make the movable film clamp return to the initial position, and at the same time make the pressure plate to arrange the film flat, and then the second clamping cylinder 507 is started to make the clamp clamp the film and tighten the film, and then the lifting cylinder 401 is started to lay the film on the top of the product, and then the film cutting cylinder 601 is started to make the film cutting blade 602 cut the film from the position close to the movable film clamp, so that the film stays on the top of the product, and then the lifting cylinder 401 is started to raise the film-pulling assembly 5 and the film-cutting assembly 6 to perform subsequent film coating operations, and at the same time it does not affect the product transportation.

[0062] In actual use, a distance sensor is set on the connecting beam 502. On the one hand, the distance sensor can detect whether the product is delivered. On the other hand, it can also detect the distance between the connecting beam 502 and the top of the product to prevent the lifting cylinder 401 from laying the film on the top of the product and then continuously descending after the film contacts the product and breaking the film.

[0063] A slider is provided on the lifting plate 402, and the slider cooperates with the lifting rail to facilitate production and processing.

[0064] A structural reinforcement rod is provided between the base 1 and the support column 201 to improve the structural strength of the connection between the support column 201 and the base 1 and to improve the load-bearing strength of the support column 201 .

[0065] An electric control system may also be provided to uniformly control the lifting cylinder 401, the film-pulling cylinder 503, the film-cutting cylinder 601, the first clamping cylinder 504 and the second clamping cylinder 507, thereby reducing the workload of workers and improving work efficiency.
