Description

Technical Field

[0001] This utility model belongs to the field of composite machine technology, specifically relating to a printable coating composite machine for acrylic double-sided tape. Background Technology

[0002] Acrylic double-sided tape is made by coating both sides of a substrate with adhesive and covering both sides of the coated substrate with release film. The double-sided tape is then wound up and packaged. During the winding process, a coating can be printed on the surface of the release film using a printing device. However, in existing equipment, the double-sided tape may become loose during winding and printing, resulting in offset of the printed coating or inconsistent printing thickness, which affects the production quality of the product. Summary of the Invention

[0003] The purpose of this invention is to provide a printable coating laminating machine for acrylic double-sided tape to solve the problem of easy loosening of double-sided tape during the printing process of existing acrylic double-sided tape printable coating laminating machines.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A printable coating laminating machine for acrylic double-sided tape includes a frame and a roller pressing assembly, a printing assembly, and a roll roller sequentially arranged on the frame. The roller pressing assembly includes two fixed plates fixed to the frame and an upper pressure roller and a lower pressure roller rotatably disposed between the two fixed plates. The printing assembly includes two mounting brackets fixed to the frame and a fixed frame fixedly mounted between the two mounting brackets. Two oppositely arranged print heads are slidably disposed within the fixed frame. Two second guide rollers are rotatably connected between the two mounting brackets on both sides of the fixed frame.

[0006] Each of the two fixed plates has a sliding rod that slides through it on one side. Each of the two sliding rods has a baffle fixedly installed at the top. Each of the two sliding rods has a rotating seat fixedly installed at the bottom. Each of the two rotating seats is fixedly connected to the two fixed plates with a spring. A tensioning shaft is rotatably connected between the two rotating seats.

[0007] Preferably, the height of the tensioning shaft and the winding roller is lower than the height of the two second guide rollers.

[0008] Preferably, two first guide rollers are rotatably connected between the two fixed plates on one side of the upper and lower pressure rollers.

[0009] Preferably, the fixed frame has sliding blocks slidably connected to both the upper and lower sides, and the fixed frame is rotatably provided with two lead screws that respectively screw into and pass through the two sliding blocks, and the two print heads are respectively fixedly connected to the two sliding blocks.

[0010] Preferably, each of the two fixed plates is slidably connected to a slider, the upper pressure roller is rotatably connected between the two sliders, and the upper pressure roller is located directly above the lower pressure roller.

[0011] Preferably, an electric push rod is fixedly installed on each of the two fixed plates, and the telescopic ends of the two electric push rods are respectively fixedly connected to the two sliders.

[0012] Preferably, one end of the upper pressure roller and the lower pressure roller are respectively provided with a first transmission component and a second transmission component. The first transmission component and the second transmission component each include an L-shaped mounting plate and a first bevel gear and a second bevel gear respectively rotatably connected to both ends of the L-shaped mounting plate, and the first bevel gear and the second bevel gear are meshed together.

[0013] Preferably, the L-shaped mounting plate of the first transmission component is fixedly connected to one of the sliders, and the L-shaped mounting plate of the second transmission component is fixedly connected to one of the fixing plates.

[0014] Preferably, the first bevel gear of the first transmission component is coaxially fixed with the upper pressure roller, and the first bevel gear of the second transmission component is coaxially fixed with the lower pressure roller.

[0015] Preferably, one of the fixed plates has a rotating shaft on one side, which slides through two second bevel gears. The rotating shaft has a groove, and the two second bevel gears are arranged opposite to each other. The inner sides of the two second bevel gears are fixedly installed with protrusions that slide in the grooves.

[0016] Compared with the prior art, this utility model has the following advantages:

[0017] (1) This utility model is provided with a slide bar, a spring, a rotating seat and a tensioning shaft. The roller pressing device applies the coated substrate and the release film on both sides to form a double-sided tape. Then the double-sided tape passes around the tensioning shaft and is pulled above the two second guide rollers. Finally, the end is fixed on the roll roller and the spring is in a compressed state. Then the double-sided tape is moved by the rotation of the roll roller and the coating is printed by the print head. During this process, the elasticity of the spring causes the rotating seat to drive the tensioning shaft to always press the double-sided tape downward, so that the double-sided tape is kept taut between the two second guide rollers, thereby ensuring the printing quality.

[0018] (2) This utility model is equipped with a lead screw and a slide block. The double-sided tape passes between the two print heads, which allows the two print heads to print the release film on both sides at the same time. By rotating the lead screw, the slide block drives the print head to move, so that the double-sided tape can be printed at different positions. The operation is simple, the efficiency is high, and the practicality is increased.

[0019] (3) The present invention is equipped with an electric push rod. The extension and retraction of the electric push rod drives the slider to move, thereby driving the upper pressure roller to move, and then adjusting the distance between the upper pressure roller and the lower pressure roller, so that double-sided tapes of different thicknesses can be squeezed and bonded, increasing practicality and avoiding the situation where the double-sided tape is damaged or the release film is shifted due to excessive squeezing force.

[0020] (4) This utility model is provided with a first transmission component, a second transmission component and a rotating shaft. By driving the rotating shaft to rotate, the slide groove and the convex strip drive the corresponding second bevel gear to rotate. Thus, through meshing transmission, the two first bevel gears drive the upper pressure roller and the lower pressure roller to rotate respectively. Since the two second bevel gears are arranged opposite each other, the upper pressure roller and the lower pressure roller rotate relative to each other, so as to realize the squeezing and conveying of the double-sided tape by the upper pressure roller and the lower pressure roller. Thus, the upper pressure roller and the lower pressure roller can be driven to rotate simultaneously by one driving device, which reduces the manufacturing cost of the equipment and improves its practicality. Moreover, the convex strip and the slide groove allow the first transmission component to move along the rotating shaft, so as not to affect the movement adjustment of the upper pressure roller.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 As shown, this utility model provides the following technical solution:

[0029] A printable coating laminating machine for acrylic double-sided tape includes a frame 1 and a roller pressing assembly, a printing assembly, and a roll roller 13 sequentially arranged on the frame 1. The roller pressing assembly includes two fixed plates 2 fixed on the frame 1 and an upper pressure roller 4 and a lower pressure roller 6 rotatably arranged between the two fixed plates 2. The printing assembly includes two mounting brackets 11 fixed on the frame 1 and a fixed frame 10 fixedly installed between the two mounting brackets 11. Two oppositely arranged print heads 15 are slidably arranged inside the fixed frame 10. Two second guide rollers 12 are rotatably connected between the two mounting brackets 11 on both sides of the fixed frame 10.

[0030] Each of the two fixed plates 2 has a sliding rod 8 that slides through one side. Each of the two sliding rods 8 has a baffle 7 fixedly installed at the top. Each of the two sliding rods 8 has a rotating seat 18 fixedly installed at the bottom. Each of the two rotating seats 18 is fixedly connected to the two fixed plates 2 with a spring 9. Each of the two rotating seats 18 is rotatably connected to a tensioning shaft 17.

[0031] The height of tensioning shaft 17 and winding roller 13 is lower than the height of the two second guide rollers 12;

[0032] Two first guide rollers 3 are rotatably connected between the two fixed plates 2 on one side of the upper pressure roller 4 and the lower pressure roller 6.

[0033] Based on the above disclosed structure, when producing double-sided tape:

[0034] First, the coated substrate and the release film on both sides are conveyed from one end of the frame 1 to between the upper pressure roller 4 and the lower pressure roller 6, and the release film on both sides is made to pass around the two first guide rollers 3 respectively, so as to avoid the release film and the coated substrate from contacting each other during the movement and to avoid displacement. Then, under the squeezing action of the upper pressure roller 4 and the lower pressure roller 6, the coated substrate and the release film on both sides are bonded to form a double-sided tape. Then, the end of the double-sided tape is passed around the tension shaft 17 and through the top of the two second guide rollers 12, and finally the end of the double-sided tape is fixed to the winding roller 13. At this time, the spring 9 is in a compressed state. Then, by rotating the winding roller 13, the double-sided tape is wound up and moved. When the double-sided tape moves between the two second guide rollers 12, the print head 15 prints the coating on both sides of the double-sided tape, and finally the double-sided tape is wound around the outside of the winding roller 13, thus completing the production of the double-sided tape.

[0035] Preferably, since the height of the tensioning shaft 17 and the roll roller 13 is lower than the height of the two second guide rollers 12, the spring force of the compressed spring 9 causes the rotating seat 18 to drive the tensioning shaft to always press the double-sided tape downwards. The two slide bars 8 are set to prevent the tensioning shaft 18 from shifting to the sides, so that the double-sided tape always presses downwards against the top of the two second guide rollers 12, so that the double-sided tape is in a taut state between the two second guide rollers 12. This ensures that the double-sided tape will not shift during the printing process of the print head 15, thus guaranteeing the quality of the printed coating.

[0036] In addition, regarding the printhead 15, slide blocks 14 are slidably connected to both the upper and lower sides of the fixed frame 10. Two lead screws 16 are rotatably mounted on the fixed frame 10, each screw threaded through one of the two slide blocks 14. The two printheads 15 are fixedly connected to the two slide blocks 14 respectively. Based on this, by driving the lead screws 16 to rotate, the two slide blocks 14 slide left and right along the lead screws 16 within the fixed frame 10, thereby driving the two printheads 15 to move left and right. This allows for printing coatings on double-sided tape at different positions, enabling the substrate and release films on both sides to enter between the upper pressure roller 4 and the lower pressure roller 6 at any position, preventing coating offset during printing, improving production efficiency, and increasing practicality.

[0037] Furthermore, regarding the upper pressure roller 4, sliders 23 are slidably connected within both fixed plates 2, and the upper pressure roller 4 is rotatably connected between the two sliders 23, positioned directly above the lower pressure roller 6. Electric push rods 5 are fixedly installed on both fixed plates 2, with their telescopic ends fixedly connected to the two sliders 23 respectively. Based on this, by extending the telescopic ends of the electric push rods 5, the sliders 23 move downwards, thereby causing the upper pressure roller 4 to move downwards closer to the lower pressure roller 6. This adjusts the gap between the upper pressure roller 4 and the lower pressure roller 6, allowing for the compression and bonding of double-sided adhesive tape formed from substrates of different thicknesses and release films on both sides, increasing practicality and preventing damage to the double-sided adhesive tape or displacement of the release film due to excessive pressure.

[0038] Regarding the driving of the upper pressure roller 4 and the lower pressure roller 6, the following structure is preferably provided:

[0039] The upper pressure roller 4 and the lower pressure roller 6 are respectively provided with a first transmission assembly and a second transmission assembly at one end. The first transmission assembly and the second transmission assembly each include an L-shaped mounting plate 22 and a first bevel gear 19 and a second bevel gear 20 respectively rotatably connected to both ends of the L-shaped mounting plate, and the first bevel gear 19 and the second bevel gear 20 are meshed together.

[0040] The L-shaped mounting plate 22 of the first transmission component is fixedly connected to one of the sliders 23, and the L-shaped mounting plate 22 of the second transmission component is fixedly connected to one of the fixing plates 2.

[0041] The first bevel gear 19 of the first transmission assembly is fixed coaxially with the upper pressure roller 4, and the first bevel gear 19 of the second transmission assembly is fixed coaxially with the lower pressure roller 6.

[0042] One of the fixed plates 2 has a rotating shaft 21 on one side. The rotating shaft 21 slides through two second bevel gears 20. A groove 24 is provided on the rotating shaft 21. The two second bevel gears 20 are arranged opposite to each other. A protrusion 25 that slides in the groove 24 is fixedly installed on the inner side of each of the two second bevel gears 20.

[0043] As can be seen from the above, the rotation of the shaft 21 driven by the external motor causes the groove 24 on the shaft 21 to drive the two protrusions 25 to rotate, which in turn causes the two protrusions 25 to drive the two second bevel gears 20 to rotate. Then, through meshing transmission, the two meshing first bevel gears 19 rotate, which in turn drive the upper pressure roller 4 and the lower pressure roller 6 to rotate. Since the two second bevel gears 20 are arranged oppositely, the rotation directions of the two first bevel gears 19 are opposite, which causes the upper pressure roller 4 and the lower pressure roller 6 to rotate relative to each other. This enables the upper pressure roller 4 and the lower pressure roller 6 to squeeze and convey the double-sided tape. In this way, the upper pressure roller 4 and the lower pressure roller 6 can be driven to rotate simultaneously by a single drive device, which reduces the equipment manufacturing cost and improves practicality. In addition, the protrusions 25 can slide in the groove 24, which allows the first transmission component to move up and down along the shaft 21, so as not to affect the adjustment of the gap of the upper pressure roller 4 driven by the slider 23.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
