Description

Technical Field

[0001] The invention belongs to the technical field of film laminating, and in particular relates to an automatic film-cutting segmented transmission type film laminating machine and a film laminating method thereof. Background Art

[0002] Because glass products are easily worn and stained, they need to be coated during storage. Common coating machines need to cut the film along the edge of the glass after coating. Because glass products are relatively fragile, long blades are not usually suitable for cutting the film in one stroke to prevent excessive cutting force or the glass from being crushed by slight misalignment. To protect the glass, some manufacturers use manual film cutting, manually slicing the film along the edge with a blade. However, the consistency of the work quality cannot be guaranteed, and the processing efficiency is low. Some manufacturers also install a film cutting mechanism on the coating machine, using a linear module to drive the cutter to slide forward along the edge of the glass to cut the film.

[0003] For example, the patent with announcement number CN204278680U discloses a large glass coating machine, which includes a frame, a film placing device, a coating device and a film cutting device. The film cutting device can be moved back and forth and is arranged in the middle position of the discharge platform, so that it can be suitable for moving glasses of different lengths to the required film cutting position for film cutting; after film cutting, no film edge will be left on the edge of the glass, and after film cutting, the film and the glass can be completely aligned, which can effectively protect the glass from damage and scratches, and the coating effect is good.

[0004] However, the servo motor of the laminating machine drives the synchronous belt transmission mechanism to drive the cutting knife frame mechanism to slide left and right on the linear slide rail. The cutter needs to move from the leftmost side to the rightmost side to completely cut the film. The moving stroke is large and the processing efficiency is low. Summary of the Invention

[0005] The purpose of the present invention is to provide an automatic film cutting and segmented transmission type film laminating machine to solve the problem of low film cutting efficiency of existing film laminating machines.

[0006] The present invention provides the following technical solutions:

[0007] An automatic film cutting and segmented transmission laminating machine includes a roller conveyor belt, an unwinding roller, a pressure roller group, and a film cutting assembly. The sheet-like product passes through the pressure roller group and is transported by the roller conveyor belt at intervals toward the film cutting assembly. The film on the unwinding roller is stretched by the pressure roller group and then covered on the product.

[0008] The film cutting assembly includes a lifting drive member, a rotating drive member, rack 1, rack 2 and a cutter. The rotating drive member is installed at the output end of the lifting drive member. The output end of the rotating drive member is equipped with gear 1 that meshes with both rack 1 and rack 2. The rack 1 and rack 2 are distributed on the front and rear sides of the gear 1 and are staggered along the left and right directions. Cutters are installed on the left and right ends of the rack 1 and the rack 2. The rotating drive member drives the rack 1 and rack 2 to move in opposite directions, so that the cutter cuts the film between the front and rear products.

[0009] Preferably, a support frame is installed at the output end of the lifting drive member, and the rotating drive member is installed on the bottom surface of the support frame; pressure wheels 1 and 2 for pressing the film onto the product are installed on the front and rear sides of the rotating drive member on the support frame, and the pressure wheels 1 and 2 correspond to the positions of the cutter one by one, and the pressure wheels 1 and 2 move following the rack 1 and rack 2 respectively.

[0010] Preferably, the pressing wheel 1 and the pressing wheel 2 roll obliquely from the edge of the product to the product and press the film, the inclination direction of the pressing wheel 1 is opposite to the moving direction of the pressing wheel 1, and the inclination direction of the pressing wheel 2 is opposite to the moving direction of the pressing wheel 2.

[0011] Preferably, the pressure wheel 1 and the pressure wheel 2 are respectively installed on the pressure rod, the upper end of the pressure rod is hinged to the adapter block through a rotating shaft, and the adapter block is fixed on the rack 1 or the rack 2; a push block is installed on the pressure rod below the rotating shaft, and a pressure block is installed on the adapter block above the rotating shaft; a torsion spring is installed on the rotating shaft, and the two ends of the torsion spring are respectively squeezed toward each other by the pressure block and the push block.

[0012] Preferably, the pressing wheel 1 and the pressing wheel 2 both include coaxial wheel surface 1 and wheel surface 2, the wheel surface 1 is located on the near-axial side of the wheel surface 2, the wheel surface 1 is a circular surface concave by the wheel surface 2, and the wheel surface 2 presses the end of the product; the pressure rod is provided with an arc groove, and the wheel surface 2 is embedded in the arc groove.

[0013] Preferably, a pressure strip is installed on the side panel of the support frame, and the two ends of the pressure strip are respectively fixed to the side panels on the left and right sides, and the pressure strip presses the film between the front and rear groups of cutters.

[0014] Furthermore, the lifting drive member is installed on a gantry, and the gantry is installed on a linear module. When cutting the film, the linear module drives the film cutting assembly to move synchronously with the product in the same direction.

[0015] Preferably, a sensor is installed on the frame to detect that the rear end of the product passes through rack 1; the sensor is communicatively connected to the controller, and the controller is communicatively connected to the linear module, so that the linear module drives the film cutting assembly to follow the movement of the product.

[0016] Furthermore, the roller conveyor belt includes a conveying section 1 and a conveying section 2 connected in front and behind. A film cutting assembly is installed between the conveying section 1 and the conveying section 2. The pressure roller group is installed above the conveying section 2. The product is conveyed by the conveying section 2 during lamination. After the film cutting assembly cuts the film, the conveying section 1 accelerates the product to the next process.

[0017] The present invention also provides a laminating method for a laminating machine, comprising the following steps:

[0018] The sheet-like products are transported one by one and at equal intervals by a roller conveyor belt to the pressing roller group, which presses the unwound film tightly against the surface of the product and moves it towards the film cutting assembly. Adjacent products are connected by the film.

[0019] When the rear end of the product passes through the film cutting assembly, the film cutting assembly is moved and controlled to move synchronously with the product; the lifting drive lowers the cutter, and the rotating drive drives rack 1 and rack 2 to move in opposite directions, so that the cutter cuts the film along the edges of the front and rear products;

[0020] While cutting the film, the first and second pressing wheels roll along the left and right ends of the product to the surface of the product respectively, and move along with the first and second racks to press the film while cutting;

[0021] After the film cutting is completed, the lifting drive member resets the cutter upward, and the roller conveyor belt accelerates the coated product to the next process.

[0022] The beneficial effects of the present invention are:

[0023] The film cutting assembly of the present invention can realize automatic film cutting. The rotary drive member of the film cutting assembly drives rack 1 and rack 2 to move in opposite directions. Cutters are installed at both ends of rack 1 and rack 2. When rack 1 moves to the right, the cutters on its left and right ends simultaneously cut the film along the rear edge of the product until rack 1 moves into position and its two cutters completely separate the film from the product. Similarly, rack 2 also moves to the left, and the cutters on its left and right ends simultaneously cut the film along the front edge of the next product until the film is completely separated from the product. Compared with conventional film cutting devices, the above working process only requires rack 1 and rack 2 to move half the stroke to completely cut the film, which has higher processing efficiency. Only one rotary drive member is needed to drive two sets of cutters to simultaneously separate the film from the two front and back products, which has a more compact structure.

[0024] The first and second pressing wheels of the present invention roll along with the cutter, pressing the film while cutting and preventing it from warping. The first and second pressing wheels press against the product at an angle, with the inclination direction opposite to the direction of movement. The inclined pressure exerted by the pressing wheels on the product reduces the downward pressure, preventing damage to the product. Furthermore, the pressing wheels can float upward when subjected to significant thrust and friction from the product, allowing them to flexibly press against the product surface, further protecting the product.

[0025] The roller conveyor belt of the present invention is driven in sections, and includes a conveying section 1 and a conveying section 2 connected in front and behind. A pressure roller group is installed above the conveying section 2. When laminating, the conveying section 2 conveys the product at a slower speed and cooperates with the pressure roller group to make the film evenly cover the surface of the product. After the film is rolled and cut, the conveying section 1 accelerates the conveying of the product to prevent conveying interference with the next product and wear of the product.

[0034] Example 1

[0035] like Figure 1 and Figure 2 The figure shows an automatic film cutting and segmented transmission laminating machine, comprising a roller conveyor belt 1, an unwinding roller 2, a pressure roller assembly 3, and a film cutting assembly 4. Sheet-shaped products pass through the pressure roller assembly 3 and are conveyed by the roller conveyor belt 1 toward the film cutting assembly 4 at intervals. The film 6 on the unwinding roller 2 is tensioned by the pressure roller assembly 3 and then coated on the product. This embodiment uses glass as an example.

[0036] The roller conveyor belt 1 comprises a first conveyor section 21 and a second conveyor section 22, which are connected in series. A pressure roller assembly 3 is mounted above the second conveyor section 22. During lamination, the second conveyor section 22 conveys the product at a relatively slow speed, allowing the pressure roller assembly 3 to evenly coat the film 6 on the product surface. After lamination and film cutting are completed, the first conveyor section 21 accelerates the product to the next process.

[0037] Please refer to Figure 1 In order to feed the front and rear glass pieces 5 into the pressing roller group 3 at equal intervals, a blocking block 23 is installed on the inlet side of the pressing roller group 3. The blocking block 23 is lifted up by a cylinder at regular intervals to block the glass 5 coming from the rear side. When the time is up, the cylinder lowers the blocking block 23, and the glass 5 coming from the rear side is fed into the pressing roller group 3 for coating.

[0038] To prevent abrasion of the glass when blocked by block 23, a third conveyor section 24 is provided at the infeed end of roller conveyor belt 1. When block 23 is lifted, conveyor section 24 pauses until block 23 descends, at which point it resumes feeding the glass into the roller assembly. A controller is in communication with the cylinder of block 23 and the drive motor of conveyor section 24.

[0039] The pressure roller assembly 3 comprises two upper and lower pressure rollers 31. The height of the upper pressure roller can be adjusted by a lifting cylinder 32 to vary the gap between the two rollers 31, adapting to coating glass 5 of varying specifications. The lower pressure roller is driven by a motor to rotate and convey the glass 5. In this embodiment, two pressure roller assemblies 3 are mounted on the frame in a front-to-back direction to evenly apply the film 6 to the glass 5. The two pressure roller assemblies 3 operate synchronously via a gear and belt drive.

[0040] Please refer to Figure 2 and Figure 3 The film cutting assembly 4 includes a lifting drive member 41, a rotating drive member 42, a rack 1 422, a rack 2 423 and a cutter 424.

[0041] A gantry 43 is mounted on the frame, and a lifting drive member 41 is mounted on the left and right ends of the gantry 43 . The lifting drive member 41 can be a cylinder.

[0042] The output end of the lifting drive 41 is mounted on a support frame 44, and the rotation drive 42 is mounted on the bottom surface of the support frame 44. The lifting drive 41 can drive the rotation drive 42 to move up and down. The rotation drive 42 can be a motor.

[0043] Gear 1 421 is mounted on the output end of the rotary drive member 42. Gear 1 421 meshes with both rack 1 422 and rack 2 423. Rack 1 422 and rack 2 423 are located on either side of gear 1 421, staggered in the left-right direction. Cutters 424 are mounted on both the left and right ends of rack 1 422 and rack 2 423. The rotary drive member 42 drives gear 1 421 to rotate, which in turn drives rack 1 422 and rack 2 423 to move in opposite directions, causing the cutters 424 to cut the film 6 between the front and back products, breaking the film 6 along the ends of the products. For example, when rack 1 422 moves rightward, the cutters 424 on its left and right ends simultaneously cut the film 6 along the rear edge of the first product. Once rack 1 422 is in place, its two cutters 424 complete their travels, completely severing the film 6.

[0044] Please refer to Figure 3 On the support frame 44, pressure rollers 1 45 and 2 46 are mounted on the front and rear sides of the rotary drive member 42. During film cutting, they press the film 6 against the product to prevent it from being uneven or warping. The number and position of pressure rollers 1 45 and 2 46 correspond one-to-one with the cutter 424. Pressure rollers 1 45 and 2 46 follow the movement of racks 1 422 and 2 423, respectively.

[0045] Please refer to Figure 4The first and second pressure rollers 45 and 46 roll obliquely from the edge of the product onto the product and press the film 6. The tilt direction of the first pressure roller 45 is opposite to the moving direction of the first pressure roller 45, and the tilt direction of the second pressure roller 46 is opposite to the moving direction of the second pressure roller 46. For example, when the first and second pressure rollers 45 and 46 move to the right, the frictional resistance of the glass 5 against the pressure rollers causes the pressure rollers to float to the upper left, thus preventing the pressure rollers from rigidly squeezing the glass 5 and damaging it.

[0046] Specifically, an adapter block 451 is fixedly mounted on both the rack 1 422 and the rack 2 423 . The pressure roller 1 45 and the pressure roller 2 46 are respectively mounted on the pressure rod 452 . The upper end of the pressure rod 452 is hinged to the adapter block 451 via a rotating shaft 456 . A push block 455 is mounted on the pressure rod 452 below the rotating shaft 456 , and a pressure block 454 is mounted on the adapter block 451 above the rotating shaft 456 . A torsion spring 453 is sleeved on the rotating shaft 456 . The two ends of the torsion spring 453 are respectively pressed toward each other by the pressure block 454 and the push block 455 . That is, the upper end of the torsion spring 453 presses the pressure block 454 upward, and the lower end of the torsion spring 453 presses the push block 455 downward, thereby pressing the pressure rod 452 downward, causing the pressure rollers 1 45 and 46 to press the film 6 .

[0047] Please refer to Figure 3 and Figure 6 The front and rear sides of the first and second pressing rollers 45 and 46 each include a coaxial first wheel surface 457 and a second wheel surface 458. The first wheel surface 457 is located near the axis of the second wheel surface 458. The first wheel surface 457 is a circular surface concave from the second wheel surface 458. The pressure rod 452 is provided with an arcuate groove 459, and the second wheel surface 458 is inserted into the arcuate groove 459 and can rotate along the arcuate groove 459. Because the distance between the front and rear second wheel surfaces 458 is greater than the distance between the front and rear first wheel surfaces 457, the second wheel surface 458 has a larger contact area with the end of the product, which can more evenly press the film 6.

[0048] Please refer to Figure 3 and Figure 4 A pressure strip 47 is horizontally installed on the side panel of the support frame 44, and the two ends of the pressure strip 47 are respectively fixed to the side panels on the left and right sides. The pressure strip 47 is located between the front and rear groups of cutters 424, pressing downward to tighten the film 6 between the front and rear groups of cutters 424, so that the film 6 is in a tensioned state, ensuring that the film 6 is cut more smoothly.

[0049] The laminating method of this laminating machine includes the following steps:

[0050] The glass 5 is conveyed one by one by the roller conveyor belt 1 to between the upper and lower rollers 31 of the pressing roller group 3. The pressing roller group 3 presses the unwound film 6 against the surface of the glass 5. The pressing roller group 3 is driven by a motor to rotate and move the glass 5 toward the film cutting assembly 4. There is a small gap between adjacent glass glasses 5 and they are connected by the film 6.

[0051] When the rear end of the glass 5 passes through the film cutting assembly 4, the roller conveyor 1 is stopped; the lifting drive 41 lowers the cutter 424 and causes the pressure bar 47 to press down the film 6 between the front and rear sets of cutters 424; the rotating drive 42 drives the rack 1 422 and the rack 2 423 to move in opposite directions, so that the two sets of cutters simultaneously cut the film 6 along the edges of the front and rear glass 5;

[0052] While the film 6 is being cut, the first pressing wheel 45 and the second pressing wheel 46 respectively roll along the left and right ends of the two glass pieces to the product surface and move along with the first rack 422 and the second rack 423 to press the film 6 while cutting the film.

[0053] After the film cutting is completed, the lifting drive member 41 resets the cutter 424 and the pressure bar 47 upward, the rotating drive member 42 resets the rack 1 422 and the rack 2 423, and the conveying section 1 21 of the roller conveyor belt 1 accelerates the coated glass 5 to the next process.

[0054] Example 2

[0055] Based on Example 1, this embodiment synchronizes the film cutting and laminating operations to further improve the laminating efficiency. The continuous laminating also ensures the flatness of the film and avoids creases caused by conveying interruptions.

[0056] Please refer to Figure 2 A linear module 48 extending in the front-to-back direction is installed on the frame, and the gantry 43 is installed on the linear module 48. When cutting the film, the linear module 48 drives the film cutting assembly 4 and the glass 5 to move synchronously in the same direction, so that the film cutting and laminating are carried out synchronously.

[0057] In this embodiment, a photoelectric sensor 49 is mounted on the frame and is communicatively connected to a controller, which in turn is communicatively connected to the linear module 48, the lift drive 41, and the rotary drive 42. When the rear end of the glass 5 passes the photoelectric sensor 49, it generates a detection signal and transmits it to the controller. The controller then immediately controls the linear module 48 to drive the film cutting assembly 4 to follow the glass 5, and the film cutting assembly 4 begins film cutting. Once film cutting is complete, the controller resets the linear module.

[0058] In order to further improve the reliability of film cutting, two photoelectric sensors 49 are installed on the frame to detect whether the film cutting ends of the two adjacent products in front and behind have moved into place. Only when both photoelectric sensors 49 detect that the two products in front and behind have moved into place, the controller will control the linear module 48 to move and control the cutter 424 to cut the film.

[0059] The other structures of this embodiment are the same as those of embodiment 1.

[0060] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
