Description

Technical Field

[0001] The present invention relates to the technical field of film compounding machinery, and more specifically to a production device for compounding packaging bag films. Background Art

[0002] The compounding equipment for producing packaging bag films generally refers to combining two or more different types of film materials through certain processing techniques (such as dry compounding, wet compounding, solvent-free compounding, etc.) to improve the deficiencies of single material properties, thereby producing composite films with better barrier properties, heat sealability, mechanical strength, etc.

[0003] As shown in the existing film compounding equipment "such as application number: CN201821406951.9, a compound packaging bag manufacturing device", for the operation of laminating a coded film with another film, a "coating device" is used to apply glue to one of the films.

When in winter and the slurry temperature is too low, the temperature control device can be controlled to heat the slurry, and production can be carried out after heating to an appropriate temperature; when in summer and the slurry temperature is too high and the viscosity is insufficient, the control device can be operated to cool the slurry to increase the viscosity."

[0005] For the above-mentioned glue coating device for the protective film, by adjusting the appropriate temperature, the adhesion effect during glue coating is improved, but this only adjusts the temperature at the position where the glue tank is placed, and the temperature of the glue will change during the process of adding glue to the glue tank and guiding the glue in the glue tank, and there are still disadvantages of poor adhesion effect during glue coating.

[0047] As Figures 1 - 5 shown, the present invention provides: a production device for laminating packaging bag films, including;

[0048] The first film supply device a for providing the first film;

[0049] The gluing equipment b for coating glue on one side of the first film;

[0050] It further includes a drying device c for drying the glue on the first film;

[0051] The second film supply device d for providing the second film, and the second film is arranged opposite to the side of the first film coated with glue;

[0052] The laminating device e for laminating the first film and the second film into a composite film;

[0053] It further includes a controller and a curing and solidifying device (not shown in the figure). The controller is a PLC controller connected to an external power supply to supply power for and turn on / off electrical components. The generated composite film needs to be further processed by the curing and solidifying device to ensure quality.

[0054] The specific partial structure of the gluing equipment b is as follows:

[0055] The gluing equipment b includes a bracket b1, a glue tank b2 fixedly installed on the bracket b1, a glue application roller b3 and a glue guiding roller b4 rotatably installed on the bracket b1, and a glue adding pipe b5 fixedly connected to the glue tank b2. Part of the glue application roller b3 extends into the glue tank b2. The glue tank b2 is fixedly installed at the bottom inside the bracket b1. The glue application roller b3 and the glue guiding roller b4 are sequentially located directly above the glue tank b2. A glue adding pipe b5 is fixedly connected to the side of the glue tank b2. One pipe end of the glue adding pipe b5 is connected to an external glue supply device (not shown in the figure), and the other pipe end of the glue adding pipe b5 extends into the glue tank b2. The glue supply device adds glue into the glue tank b2. The glue application roller b3 contacts the glue in the glue tank b2 and adheres to the glue guiding roller b4 through rotation. The glue supply device can be a pumping device (such as a diaphragm pump) that pumps external glue into the glue adding pipe b5 through a pipe;

[0056] It further includes a temperature control device f for adjusting the temperature of the glue in the glue tank b2, the roller surface of the glue application roller b3, the roller surface of the glue guiding roller b4, and the inside of the glue adding pipe b5;

[0057] The temperature control device f includes a through pipe f1 penetrating both sides of the glue tank b2, roller cavities f2 respectively communicating with both ends of the glue application roller b3 and the glue guiding roller b4, a spiral pipe f3 attached to the outside of the glue adding pipe b5, a temperature supply component f4 connected to one end of the through pipe f1, the roller cavities f2, and the spiral pipe f3 to provide cold or hot flow inside them, and a temperature return component f5 connected to the other end of the through pipe f1, the roller cavities f2, and the spiral pipe f3 to discharge the cold or hot flow inside them. The through pipe f1 contacts the glue in the glue tank b2;

[0058] It also includes a device for generating hot or cold fluid (not shown in the figure). The hot and cold fluids can be cold and hot water or cold and hot air. The device for generating hot air can be a hot air blower, and the device for generating cold air can be the refrigeration component of a refrigerator or an air conditioner. The above-mentioned temperature supply component f4 is connected to the outlet of the device for generating cold and hot air. At the same time, the temperature return component f5 can also be connected to the air inlet of the device for generating cold and hot air to provide energy recycling or directly discharge.

[0059] The pipe f1, the spiral pipe f3, the sizing roller b3, the glue guiding roller b4, and the glue adding pipe b5 are all made of heat-conducting materials, which can be stainless steel.

[0060] The temperature supply component f4 simultaneously introduces cold or hot fluid into the pipe f1, the roller cavity f2, and the spiral pipe f3. Through the conduction of temperature, the temperature of the glue in the glue tank b2, the roller surface of the sizing roller b3, the roller surface of the glue guiding roller b4, and the inside of the glue adding pipe b5 can be adjusted. The adjustment aspect is more comprehensive, and the effect of controlling the temperature of the glue to be applied is good, so as to improve the effect of the glue adhering to the first film.

[0061] Further, the specific structure of the temperature supply component f4 is as follows:

[0062] The temperature supply component f4 includes a first branch pipe f41 fixedly installed on the bracket b1, a heat supply pipe f42, a cold supply pipe f43, a first inlet pipe f45, a second inlet pipe f46, and a third inlet pipe f48 whose one pipe ends are respectively connected and fixed to the outside of the first branch pipe f41, a first regulating valve f44 respectively connected and installed between the heat supply pipe f42 and the cold supply pipe f43, and a first rotary joint f47 installed at the other pipe end of the first inlet pipe f45. The first regulating valve f44 can be an electric butterfly valve or an electric ball valve.

[0063] The other pipe end of the first inlet pipe f45 is connected and fixed to one pipe end of the spiral pipe f3, the first rotary joint f47 is connected and fixed to one end of the roller cavity f2, and the other pipe end of the third inlet pipe f48 is connected and fixed to one end of the pipe f1.

[0064] By respectively installing a group of first regulating valves f44 between the heat supply pipe f42 and the cold supply pipe f43, the heat supply pipe f42 and the cold supply pipe f43 are respectively connected to the above-mentioned device for generating hot or cold fluid, and the cold or hot fluid is introduced into the first branch pipe f41. After being respectively shunted through the first inlet pipe f45, the second inlet pipe f46, and the third inlet pipe f48, they respectively enter the pipe f1, the roller cavity f2, and the spiral pipe f3 to transfer temperature.

[0065] The first rotary joint f47 (i.e., the rotary joint) is a sealed rotary connector that rotates 360° to convey the medium. The first rotary joint f47 is connected to the rotating sizing roller b3 and the glue guiding roller b4 to provide a sealed transfer of hot or cold fluid to the roller cavity f2.

[0066] The temperature supply component f4 further includes a second regulating valve f49 connected and installed between the first inlet pipes f45. The second regulating valve f49 can be an electric butterfly valve or an electric ball valve. When glue addition is not required, it can be closed to block the heat flow or cold flow transfer of the first inlet pipes f45 and reduce waste.

[0067] Furthermore, the specific structure of the temperature recovery component f5 is as follows:

[0068] The temperature recovery component f5 includes a second branch pipe f51 fixedly installed on the bracket b1, a temperature recovery pipe f52, a cold return pipe f53, a first outlet pipe f55, a second outlet pipe f56, and a third outlet pipe f58 whose one pipe ends are respectively externally connected and fixed to the second branch pipe f51, a third regulating valve f54 connected and installed between the temperature recovery pipe f52 and the cold return pipe f53, and a second rotary joint f57 installed at the other pipe end of the first outlet pipe f55;

[0069] The other pipe end of the first outlet pipe f55 is connected and fixed to the other pipe end of the spiral pipe f3, the second rotary joint f57 is connected and fixed to the other end of the roller cavity f2, and the other pipe end of the third outlet pipe f58 is connected and fixed to the other end of the through pipe f1;

[0070] The second rotary joint f57 (i.e., the rotary joint) is a sealed rotary connector that rotates 360° to convey the medium. The third regulating valve f54 can be an electric butterfly valve or an electric ball valve;

[0071] The structure and use of the temperature recovery component f5 are the same as those of the above temperature supply component f4 except for the second regulating valve f49. The discharge end of the spiral pipe f3 is connected by the first outlet pipe f55, the discharge end of the roller cavity f2 is connected by the second outlet pipe f56 through the second rotary joint f57, and the discharge end of the through pipe f1 is connected by the third outlet pipe f58. In this way, they enter the second branch pipe f51 centrally and flow centrally, and then are discharged centrally by the corresponding temperature recovery pipe f52 and cold return pipe f53.

[0072] Furthermore, the specific structure of the glue application roller b3 is as follows:

[0073] The glue application roller b3 includes an outer roller b31, an inlet roller pipe b32 and an outlet roller pipe b33 respectively connected and fixed to both roller ends of the outer roller, an inner roller b34 arranged inside the outer roller b31, a connecting block b35 fixedly connected between the inside of the outer roller b31 and the outside of the inner roller b34, and a conical convex block b36 fixedly arranged in the center of the roller end of the inner roller b34. An annular cavity communicating the inlet roller pipe b32 and the outlet roller pipe b33 is formed between the outer roller b31 and the inner roller b34;

[0074] At both ends of the outer roller b31, the outlet pipes b33 are symmetrically fixed. The outlet pipes b33 also serve as rotating shafts and pass through the bracket b1 and are rotationally connected through rotating parts such as bearings. An inner roller b34 is centrally arranged inside the outer roller b31, and a plurality of connecting blocks b35 are evenly distributed between them for connection and fixation. The annular cavity formed between the outer roller b31 and the inner roller b34 is communicated with the outlet pipes b33 (this communication cavity is the above-mentioned roller cavity f2). The two groups of outlet pipes b33 are respectively fixedly installed with the first rotary joint f47 and the second rotary joint f57 to provide the flow effect of the heat flow or cold flow pair. With this structure, the heat flow or cold flow can uniformly and closely contact and flow on the inner side surface of the outer roller b31 to improve the efficiency and uniformity of temperature transfer;

[0075] As Figures 3 - 5 shown, the conical convex block b36 is in a shape similar to a cone and is centered at the roller end of the inner roller b34. When the heat flow or cold flow flows into the roller end of the inner roller b34, it can conduct annular diversion and diffusion, reduce the impact and improve the uniformity of annular flow.

[0076] As Figure 3 shown, the sizing roller b3 and the glue guiding roller b4 have the same structural composition. As Figure 2 shown, the difference is that the sizing roller b3 is larger (but the sizing roller b3 and the glue guiding roller b4 can also be of the same size).

[0077] In addition to the partial structures of the above-mentioned gluing device b, the following are other specific structures:

[0078] It also includes a traction mechanism b6 for guiding the transmission of the first film and driving the first film to contact the glue guiding roller b4;

[0079] The traction mechanism b6 includes a telescopic driver b61 fixedly installed on the bracket b1, a U-shaped rod b62 fixed to the output end of the telescopic driver b61, two groups of movable plates b63 symmetrically fixed at the bottom end of the U-shaped rod b62, a movable cavity b64 arranged on the bracket b1, a guide roller b65 rotatably installed between the two groups of movable plates b63, a first rotary driver b66 fixed to one roller end of the guide roller b65, a first support plate b67 fixedly installed outside the first rotary driver b66, and a rolling part b68 fixedly installed on the movable plate b63. The movable plate b63 is provided with a guide groove in the movable cavity b64, and the movable plate b63 is in fit with the guide groove through the rolling part b68. The outside of the first support plate b67 is fixed to the movable plate b63;

[0080] The telescopic driver b61 can be a cylinder or an electric push rod, the first rotary driver b66 can be a servo motor, and the rolling part b68 can be a universal ball;

[0081] The telescopic driver b61 is installed at the top of the bracket b1, and the output end of the telescopic driver b61 is vertically downward and fixedly connected with a U-shaped rod b62. The front and rear bottom ends of the U-shaped rod b62 are respectively fixedly installed with movable plates b63. Movable cavities b64 are symmetrically arranged at the front and rear positions of the bracket b1 for the movable plates b63 to be placed in and move. A guide roller b65 is arranged between the front and rear groups of movable plates b63. The front and rear roller ends of the guide roller b65 respectively penetrate through the movable plates b63 and are rotationally connected through rotating parts such as bearings. By the operation of the telescopic driver b61, the guide roller b65 can be driven to move up and down to adjust the vertical height position. The first film is attached to the bottom end of the guide roller b65 for transmission. When adjusting the height, the first film is brought close to the top end of the glue guiding roller b4 to adhere glue. The rolling parts b68 fixedly installed symmetrically at the left and right ends of the movable plate b63 are attached to (such as Figures 4 - 5 ) the guide grooves in the movable cavity b64 to provide guiding support and improve the stability of the movable plate b63.

[0082] It also includes a driving mechanism b7 for driving the glue applying roller b3 and the glue guiding roller b4 to rotate relatively in opposite directions;

[0083] The driving mechanism b7 includes a backing plate b71 fixedly installed on the bracket b1, a second rotating driver b72 fixedly installed on the backing plate b71, a first gear b73 fixed to the output end of the second rotating driver b72, a second gear b74 meshing with the first gear b73, and a third gear b75 meshing with the second gear b74. The second gear b74 is fixedly installed on the roller end of the glue applying roller b3, and the third gear b75 is fixedly installed on the roller end of the glue guiding roller b4;

[0084] The second rotating driver b72 can be a servo motor. The second gear b74 is surrounded and fixed on the outlet roller tube b33 of the glue applying roller b3, and the third gear b75 is surrounded and fixed on the outlet roller tube b33 of the glue guiding roller b4. When the second rotating driver b72 operates, the first gear b73 can be driven to rotate, and then the mutually meshing second gear b74 and third gear b75 are driven to rotate in opposite directions, that is, driving the glue applying roller b3 and the glue guiding roller b4 to rotate relatively in opposite directions.

[0085] The gluing device b also includes a stirring mechanism b8 fixedly installed on the glue tank b2. The stirring mechanism b8 is connected to and operates with the driving mechanism b7, and is used to mix the glue in the glue tank b2 and stir the glue with adjusted temperature, so as to improve the overall temperature uniformity, and the stirring mechanism b8 will not contact the pipe f1 when operating;

[0086] The stirring mechanism b8 includes a rotating rod b81 penetrating through the opposite sides of the glue tank b2, and multiple groups of stirring blades b82 evenly fixedly installed on the outer side of the rotating rod b81. The rotating rod b81 is rotatably connected to the glue tank b2, and one end of the rotating rod b81 is fixed to the output end of the driving mechanism b7;

[0087] As Figures 3 - 5 shown, one end of the rotating rod b81 is fixed to the rotation center of the first gear b73, and the other end of the rotating rod b81 penetrates into the glue tank b2. At the penetrating position, rotating components such as bearings are used for rotational support, and components such as mechanical seals are used to seal the rotational position to prevent the glue from running out. When the first gear b73 rotates, the rotating rod b81 can be synchronously driven to rotate, and the stirring blade b82 rotates to stir the glue, with good linkage performance.

[0088] The control method of the present invention is controlled by manually starting and closing the switch. The wiring diagram of the power element and the power supply are common knowledge in the art, and the present invention mainly aims to protect the mechanical device.
