Description

Technical Field

[0001] The invention relates to the technical field of plastic molding or connection, in particular to a film hot pressing device and a film hot pressing machine. Background Art

[0002] The prior art requires hot pressing the adhesive film onto the body of the toner bottle. During hot pressing, the adhesive film is first unfolded and attached to the body of the bottle-shaped product, and then hot pressed by an adhesive film hot pressing device to connect the adhesive film to the bottle body.

[0003] However, on the one hand, the bottle body is generally a curved surface, which makes it difficult to fit the film to the bottle body before the hot pressing operation, and then the film is prone to wrinkles after hot pressing, causing product quality problems.

[0004] On the other hand, the thickness of the bottle body is thinner than that of the bottle mouth, and the bottle body is not easy to support. Hot pressing can easily cause structural deformation of the bottle-shaped product. In addition, hot pressing of the bottle body has higher control requirements on hot pressing time, temperature, etc. Hot pressing time that is too long or temperature that is too high can easily cause hot pressing deformation of the bottle-shaped product. Hot pressing time that is too short or temperature that is too low can easily lead to insufficient connection strength between the film and the bottle-shaped product, resulting in poor connection. Summary of the invention

[0005] One of the purposes of the present invention is to provide a film hot pressing device which is helpful to avoid wrinkles in the film.

[0006] In order to achieve the above-mentioned purpose, the adhesive film hot pressing device provided by the present invention includes a driving unit and a hot pressing unit, the hot pressing unit includes a base and a hot pressing head, the driving unit drives the hot pressing unit to move along a first direction, along the first direction, the hot pressing head is fixed at one end of the base close to the hot pressing position; the hot pressing unit also includes a positioning block, the positioning block is slidably mounted on the base, the sliding direction of the positioning block relative to the base is along the first direction, and a hot pressing channel is provided on the positioning block; along the first direction, the positioning block is located on a side of the hot pressing head close to the hot pressing position, and the hot pressing head is opposite to the hot pressing channel.

[0007] As can be seen from the above, the present invention has a structural design for the film hot pressing device. During the process of hot pressing the film for the product, before the hot pressing head contacts the film, the positioning pressing block is first pressed onto the film to make the film fit well with the product. In this way, when the hot pressing head presses against the film, no wrinkles will appear on the film. Moreover, before the hot pressing head breaks contact with the film, the positioning pressing block is always pressed on the film. In this way, the hot pressing head is prevented from taking the film away during the process of breaking away from the film, and the film is prevented from loosening from the product, thereby ensuring the hot pressing quality of the film and the product.

[0008] A preferred solution is that an elastic member is provided between the base and the positioning pressing block.

[0009] Another preferred solution is that the hot pressing unit further comprises at least two sliding rods whose length direction is along the first direction, the elastic member is a coil spring, and the positioning pressing block is slidably mounted on the base through the sliding rods.

[0010] A second object of the present invention is to provide a film hot pressing device which is beneficial to avoiding wrinkles in the film and realizing automated production.

[0011] In order to achieve the above-mentioned purpose, the film hot pressing machine provided by the present invention includes a frame, a material storage device, a material transmission device, a material cutting device, a controller and the aforementioned film hot pressing device, the material storage device, the material transmission device, the material cutting device and the controller are all installed on the frame, and the driving unit is installed on the frame; the controller is communicatively connected with the material transmission device, the controller is communicatively connected with the material cutting device, and the controller is communicatively connected with the driving unit.

[0012] It can be seen from the above that the use of the aforementioned film hot pressing device can avoid wrinkles in the film and ensure the hot pressing quality of the film and the product; in addition, due to the setting of the storage device, the material transfer device, the cutting device and the controller, it is conducive to the realization of automatic gluing of the product, and further conducive to the stable control of the temperature, time, etc. of the gluing production, which is conducive to improving the quality of the gluing products.

[0013] A preferred solution is that the material feeding device includes a film driving component and a guide material feeding component, the guide material feeding component has a guide material feeding channel, the guide material feeding channel extends along the second direction, along the second direction, the guide material feeding component is located between the film driving component and the film hot pressing device, and the second direction is perpendicular to the first direction.

[0014] As can be seen from the above, the film driving component drives the film to be fed along the guide conveying channel. Under the limitation of the guide conveying channel, it is beneficial to ensure the stability of the film shape and to enable the film reaching the hot pressing position to better match and fit the product.

[0015] A further solution is that the film driving assembly includes an active material transfer roller, a pressure roller and a stretching roller, and the axes of the active material transfer roller, the pressure roller and the stretching roller are all along the third direction, the third direction is perpendicular to the second direction, and the third direction is perpendicular to the first direction; the active material transfer roller and the pressure roller are distributed along the first direction, and along the second direction, the stretching roller is located on the side of the active material transfer roller that is away from the model material transfer assembly, and the projection of the stretching roller overlaps with the projection of the main material transfer roller.

[0016] As can be seen from the above, when the film driving assembly is in use, after the film is drawn out from the storage device, it first passes through the tensioning roller from the space between the tensioning roller and the active material transfer roller, and then is led to between the active material transfer roller and the pressure roller. The film is squeezed between the active material transfer roller and the pressure roller, and the rotation of the active material transfer roller drives the film to be fed; because the film first passes through the tensioning roller before contacting the active material transfer roller, under the restriction of the tensioning roller, the film is led from one side of the active material transfer roller to between the active material transfer roller and the pressure roller, which is beneficial to increase the contact area between the film and the active material transfer roller, and to avoid slipping between the film and the active material transfer roller.

[0017] A further solution is that the frame is provided with two vertical frames distributed along the third direction, and the active material transfer roller and the material stretching roller are rotatably mounted on the vertical frames; it also includes two adjusting mechanisms, the two adjusting mechanisms correspond one to one with the two vertical frames, each adjusting mechanism is installed on the corresponding vertical frame in a positionally adjustable manner in the first direction, and the pressure roller is rotatably mounted on the adjusting mechanism.

[0018] As can be seen from the above, by operating the adjustment mechanism to move up and down, the extrusion force of the pressure roller and the active material transfer roller on the film can be adjusted, and then the extrusion force between the film and the active material transfer roller can be adjusted, and the friction between the film and the active material transfer roller can be adjusted.

[0019] A further solution is that the cutting device includes a blade and a driving device, the driving device drives the blade to move, and the controller is communicatively connected with the driving device; the guide material transfer assembly includes a first material transfer group and a second material transfer group, the first material transfer group and the second material transfer group are distributed along a second direction, and along the second direction, the guide material transfer channel of the first material transfer group is opposite to the guide material transfer channel of the second material transfer group, and a cutting gap is left between the first material transfer group and the second material transfer group for the blade to pass through.

[0020] As can be seen from the above, on the one hand, both ends of the film at the cutting position of the blade are constrained by the guide material transfer channel, which facilitates the cutting of the blade. On the other hand, since there are guide material transfer channels on both sides of the blade, the film can still be conveyed along the guide material transfer channel after being cut, avoiding abnormal material transfer.

[0021] A further solution is that a product support is also provided on the frame, the first direction is a vertical direction, and the product support is located below the hot pressing position; the film hot press is used to apply film to bottle-shaped products, and a supporting platform is provided on the frame, extending along the second direction toward the hot pressing position, and the supporting platform extends into the bottle cavity of the bottled product.

[0022] As can be seen from the above, when the adhesive film and the bottle-shaped product are hot-pressed, the bottle body wall of the bottle-shaped product is squeezed between the hot-pressing head and the supporting platform, avoiding the hot-pressing head from squeezing and deforming the bottle-shaped product, so that a suitable amount of squeezing force can be applied between the bottle body of the bottle-shaped product and the adhesive film during the hot-pressing process.

[0023] A further solution is that a positioning base surface is provided on the frame, and along the second direction, the positioning base surface is located on the side of the hot pressing position close to the material conveying device, and the positioning base surface faces the hot pressing position; a hot pressing switch for triggering the hot pressing product is provided on the positioning base surface, and the hot pressing switch is communicatively connected with the controller.

[0045] Please refer to Figure 4 , along the Z-axis direction, the positioning block 533 is located below the hot pressing head 532, a hot pressing channel is provided on the positioning block 533, and the hot pressing head 532 faces the hot pressing channel. Optionally, in this embodiment, the hot pressing direction of the hot pressing unit 53 is along the Z-axis direction, and the coil spring 534 can be eliminated at this time, so that the positioning block 533 slides below the hot pressing head 532 under the action of gravity.

[0046] Please refer to Figure 2 and Figure 3 The frame 1 has a positioning base surface 13, the positioning base surface 13 faces the positive direction of the Y axis, the positioning base surface 13 is opposite to the hot pressing position, and a bearing platform 15 protrudes from the positioning base surface 13 along the positive direction of the Y axis.

[0047] Please refer to Figures 1 to 4 Before hot-pressing the adhesive film 7 on the body of the toner bottle 6, the bottle mouth of the toner bottle 6 faces the negative direction of the Y axis, and the toner bottle 6 moves toward the positioning base surface 13 along the negative direction of the Y axis, and the support platform 15 is inserted into the bottle cavity from the bottle mouth of the toner bottle 6, and the inner wall of the body of the toner bottle 6 is supported on the support platform 15 along the Z axis. When hot-pressing the adhesive film 7 on the body of the toner bottle 6, the material transfer device 3 first drives the adhesive film 7 to move along the positive direction of the Y axis until the adhesive film 7 extends above the body of the toner bottle 6, and then the hot-pressing cylinder 51 drives the hot-pressing unit 53 to move along the negative direction of the Z axis, and the positioning pressing block 533 in the hot-pressing unit 53 first contacts the adhesive film 7, and the bottle wall of the toner bottle 6 Squeezed between the positioning block 533 and the supporting platform 15, the positioning block 533 presses the film 7 to fit the bottle body of the toner bottle 6, and the positioning block 533 stops moving after contacting the film 7. Then, as the piston rod 512 continues to extend, the coil spring 534 gradually shortens, and the hot pressing head 532 continues to move downward until the hot pressing head 532 passes through the hot pressing channel and presses on the film 7, and the piston rod 512 stops extending downward; during the retraction of the piston rod 512, the hot pressing head 532 first breaks away from contact with the film 7, and then as the hot pressing unit 53 continues to move upward, the positioning block 533 breaks away from contact with the film 7.

[0048] After completing one heat pressing, the driving cylinder 41 drives the blade 42 to pass through the gap between the first feeding group 321 and the second feeding group 322, and the blade 42 cuts the film 7, which is convenient for taking away the carbon powder bottle 6 after heat pressing; because the blade 42 is arranged between the first feeding group 321 and the second feeding group 322, on the one hand, both ends of the film 7 at the cutting position of the blade 42 are bound by the guide feeding channel, which is convenient for the cutting of the blade 42; on the other hand, because there are guide feeding channels on both sides of the blade 42, the film 7 can still be transmitted along the guide feeding channel after being cut, avoiding abnormal feeding.

[0049] Before the hot pressing head 532 contacts the adhesive film 7, the positioning pressing block 533 is first pressed onto the adhesive film 7 to make the adhesive film 7 fit well with the body of the toner bottle 6. In this way, when the hot pressing head 532 presses against the adhesive film 7, no wrinkles will appear on the adhesive film 7. In addition, before the hot pressing head 532 breaks away from the adhesive film 7, the positioning pressing block 533 is always pressed on the adhesive film 7. In this way, the hot pressing head 532 is prevented from driving the adhesive film 7 upwards during the process of breaking away from the adhesive film 7, thereby preventing the adhesive film 7 from loosening from the body of the toner bottle 6 and ensuring the hot pressing quality of the adhesive film 7 and the toner bottle 6.

[0050] Furthermore, the supporting platform 15 is arranged so that when the adhesive film 7 and the toner bottle 6 are hot pressed, the bottle wall of the toner bottle 6 is squeezed between the hot pressing head 532 and the supporting platform 15, so that during the hot pressing process, a suitable squeezing force can be applied between the bottle body of the toner bottle 6 and the adhesive film 7 to prevent the hot pressing head 532 from squeezing and deforming the toner bottle 6.

[0051] In addition, the provision of the positioning base surface 13 is beneficial to the positioning of the carbon powder bottle 6 in the Y-axis direction, and is beneficial to improving the position accuracy of the adhesive film 7 when hot pressing on the bottle body.

[0052] Preferably, a product bracket 12 is provided on the frame 1, and the product bracket 12 is located at the positive end of the frame 1 along the Y-axis direction. The product bracket 12 protrudes from the frame 1 along the positive direction of the Y-axis. The product bracket 12 is located below the supporting platform 15, and the toner bottle 6 is placed on the product bracket 12, which is beneficial to the positioning of the toner bottle 6 in the Z-axis direction, which is further beneficial to improve the position accuracy of the hot pressing of the adhesive film 7 on the bottle body.

[0053] Preferably, a hot pressing switch 14 is provided on the positioning base surface 13. Before hot pressing the adhesive film 7 on the bottle body of the toner bottle 6, when the toner bottle 6 is moved in the negative direction of the Y-axis until it abuts the positioning base surface 13, the toner bottle 6 triggers the hot pressing switch 14, and the adhesive film hot pressing machine automatically starts the hot pressing action. This is beneficial to simplifying the hot pressing operation process on the one hand, and on the other hand, it is also beneficial to improving the hot pressing efficiency.

[0054] The design of the controller, the hot pressing switch 14 and the feedback sensor 310 enables the controller to automatically control the hot pressing process of the film hot pressing machine, automatically control the time of each process in the hot pressing process, avoid the hot pressing time being too long or too short, avoid the hot pressing temperature being too high or too low, and improve the stability of the hot pressing quality.

[0055] Preferably, a roller 16 is provided at the bottom of the frame 1, and the arrangement of the roller 16 facilitates the movement of the entire film heat press.

[0056] Finally, it should be emphasized that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
