Description

Technical Field

[0001] The invention belongs to the technical field of label production, and in particular relates to a feeding device of a shearing machine for self-adhesive printing labels. Background Art

[0002] Self-adhesive printed labels are made of a composite material with paper as the front, adhesive on the back, and silicone-coated protective paper as the backing. The finished label is produced through printing and die-cutting. Self-adhesive labels primarily consist of a facestock, film, adhesive, and backing paper. Common film materials include transparent polyester, translucent polyester, and transparent oriented polypropylene, primarily used to enhance the label's protective properties and gloss.

[0003] Before labels are cut, the film material needs to be laminated to the surface material via rolling. During this process, the film material (such as PET, BOPP, etc.) has high ductility, while the surface material has poor ductility. This significant difference between the two makes the film material prone to wrinkling due to uneven stretching or contraction during the rolling process. However, the surface material, due to its poor ductility, is less prone to wrinkling. To eliminate wrinkles in the film material, the present invention provides a feeding device for a shearing machine for self-adhesive printed labels. Summary of the Invention

[0004] The purpose of the present invention is to provide a feeding device for a shearing machine for self-adhesive printing labels in view of the shortcomings of the prior art, so as to solve the technical problems in the prior art.

[0005] The objectives of the present invention can be achieved through the following technical solutions: a feeding device of a shearing machine for self-adhesive printing labels, which includes a base frame, side rollers are installed on one side of the base frame, feed rollers are installed on the other side of the base frame, top rollers and bottom rollers are installed on the top and bottom of the base frame respectively, and a roller pressure pair and a lifting component are installed in the base frame; a horizontal plate is fixedly installed on the base frame, an adjustment component is installed on the horizontal plate, and the adjustment component is driven by a controller; the adjustment component includes a fixed frame, a motor is installed on one side of the fixed frame, a rotating drum is installed in the fixed frame, the output end of the motor is connected to the rotating shaft, and the two sides of the rotating shaft are respectively connected to the transmission sleeve, a rotating plate is rotatably installed on the transmission sleeve, the rotating plate is connected to the sliding sleeve, and the sliding sleeve and the rotating drum are slidably matched.

[0006] As a further optimization or improvement of this solution, a baffle is installed on the fixed frame, a U-shaped frame is installed on the baffle, an adjusting knob is installed on the U-shaped frame, and the adjusting knob pushes the pressure roller to move toward the outer wall of the sliding sleeve.

[0007] As a further optimization or improvement of this solution, a sliding groove is provided on the rotating drum, the sliding sleeve is slidably engaged with the sliding groove, a transverse groove is provided on the sliding groove, and the rotating plate is slidably engaged with the transverse groove.

[0008] As a further optimization or improvement of this solution, a tilting groove is provided at the center of the rotating drum, and a rubber layer is installed on the tilting groove.

[0009] As a further optimization or improvement of this solution, a rotary head is rotatably mounted on the transmission sleeve, the rotary head is connected to a tilting plate via a connecting rod, and the tilting plate slides in the tilting groove.

[0010] As a further optimization or improvement of this solution, the lifting assembly includes a guide rail, the guide rail is installed on the inner wall of the base frame, a guide seat is slidably installed on the guide rail, and an adjusting roller is fixedly installed on the guide seat.

[0011] As a further optimization or improvement of this solution, a fixed plate is fixedly installed on the inner wall of the base frame, and gear one and gear two are rotated on the fixed plate, gear one is meshed with gear two, a turbine is coaxially installed on gear one, a rotating rod is rotatably installed on the base frame, a worm is sleeved on the rotating rod, the worm is meshed with the turbine, a screw is coaxially installed on gear two, the screw is connected to the transmission head, and the transmission head is fixedly installed on the guide seat.

[0012] Beneficial effects of the present invention: (1) During the operation of the present invention, the fabric layer is laminated to the drum due to the rolling of the fabric around the drum. Under the same conditions, the stretchability of the film layer on the fabric layer is greater than that of the fabric layer. Therefore, by rolling the fabric around the drum, the slight wrinkles on the film layer can be flattened, so that the film layer and the fabric layer are laminated.

[0013] (2) The motor of the present invention drives the rotating shaft to rotate, and the rotating shaft drives the transmission sleeves on both sides of the rotating shaft to move relative to each other, so that the transmission sleeves drive the sliding sleeves to move away from each other through the rotating plate, and the sliding sleeves drive the baffle to move synchronously, so that the rolled fabric wrapped on the rotating drum between the sliding sleeves is stretched, so that the film layer material is flattened by the stretching effect.

[0014] (3) The present invention installs a rubber layer in the center of the drum. When the rolled fabric is wrapped around the drum, the fabric layer adheres to the rubber layer. When the sliding sleeve moves relative to the drum, the transmission sleeve drives the rotor to move synchronously. Under the action of the connecting rod, the rotor drives the tilting plate to slide downward along the tilting groove, extracting the gas inside the tilting groove. The surface of the rubber layer shrinks, causing the rubber layer to tighten the fabric layer, thereby protecting the fabric layer and preventing the fabric layer from being overstretched and thus tearing.

DETAILED DESCRIPTION

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0030] See also Figures 1-6 A feeding device of a shearing machine for self-adhesive printing labels includes a base frame 1, side rollers 3 are installed on one side of the base frame 1, feeding rollers 9 are installed on the other side of the base frame 1, top rollers 4 and bottom rollers 5 are respectively installed on the top and bottom of the base frame 1, and a roller pressing pair 6 and a lifting assembly 7 are installed inside the base frame 1; a horizontal plate 2 is fixedly installed on the base frame 1, and an adjusting assembly 8 is installed on the horizontal plate 2, and the adjusting assembly 8 is driven by a controller 10; the adjusting assembly 8 includes a fixed frame 801, a motor 802 is installed on one side of the fixed frame 801, a rotating drum 803 is installed in the fixed frame 801, the output end of the motor 802 is connected to a rotating shaft 804, and both sides of the rotating shaft 804 are respectively connected to a transmission sleeve 808, a rotating plate 809 is rotatably installed on the transmission sleeve 808, the rotating plate 809 is connected to a sliding sleeve 805, and the sliding sleeve 805 slides with the rotating drum 803.

[0031] Specifically, a sliding groove 818 is provided on the rotating drum 803 , the sliding sleeve 805 is slidably engaged with the sliding groove 818 , a transverse groove 807 is provided on the sliding groove 818 , and the rotating plate 809 is slidably engaged with the transverse groove 807 .

[0032] For details, see Figure 10 A baffle 817 is installed on the fixing frame 801 , a U-shaped frame 814 is installed on the baffle 817 , an adjusting knob 815 is installed on the U-shaped frame 814 , and the adjusting knob 815 pushes the pressure roller 816 to move toward the outer wall of the sliding sleeve 805 .

[0033] It should be noted that a baffle 817 is installed on the fixed frame 801 for horizontal sliding. During use, the baffle 817 presses the surface material through the pressure roller 816 thereon, and the surface material fits the sliding sleeve 805, so that the sliding sleeve 805 is connected to the baffle 817, so that the sliding sleeve 805 and the baffle 817 can move synchronously.

[0034] It should be noted that, see Figure 11 The surface material is transported to the roller pair 6 through the top roller 4 and the side roller 3 in turn, and the film material is transported to the roller pair 6 through the bottom roller 5. The film material is rolled onto the surface material under the action of the roller pair 6. After rolling, the material first goes around the adjusting component 8 and is finally sent out through the lifting component 7 and the feeding roller 9.

[0035] This is for the situation where after the film material and the surface material are rolled together, the film layer has wrinkles while the surface material is normal.

[0036] The present invention inserts the rolled fabric between the sliding sleeve 805 and the baffle 817, and after the fabric is wound around the drum 803, it is discharged from between the sliding sleeve 805 and the baffle 817 at the other end. Figure 12As shown, by adjusting the adjustment knob 815, the pressure roller 816 is controlled to press the fabric, so that the fabric is attached to the sliding sleeve 805. During operation of the equipment, the fabric layer is attached to the rotating drum 803 due to the rolling of the fabric around the rotating drum 803. Under the same conditions, the film layer on the fabric layer has a greater degree of stretching than the fabric layer. Therefore, by rolling the fabric around the rotating drum 803, slight wrinkles on the film layer can be flattened, so that the film layer and the fabric layer are attached.

[0037] In response to the situation where the membrane material has a large degree of wrinkles, the present invention starts the motor 802, and the motor 802 drives the rotating shaft 804 to rotate. The rotating shaft 804 drives the transmission sleeves 808 on both sides of the rotating shaft 804 to move relative to each other, so that the transmission sleeves 808 drive the sliding sleeves 805 to move away from each other through the rotating plate 809, and the sliding sleeves 805 drive the baffle 817 to move synchronously. At the same time, the sliding sleeves 805 drive the rolled fabric on it to move synchronously, so that the rolled fabric wrapped around the rotating drum 803 between the sliding sleeves 805 is stretched, and the membrane material is flattened by the stretching effect.

[0038] It should be noted that the feeding positions of the surface material and the film layer material can be exchanged. The controller 10 drives the fixed frame 801 to rotate, so that the rotating drum 803 tilts, thereby controlling the left and right direction of the rolled fabric.

[0039] See also Figure 7-Figure 9 The rotating drum 803 is provided with an inclined groove 812 at the center thereof, and a rubber layer 806 is installed on the inclined groove 812 .

[0040] Specifically, a rotary head 810 is rotatably mounted on the transmission sleeve 808 . The rotary head 810 is connected to a tilting plate 813 via a connecting rod 811 . The tilting plate 813 slides in the tilting groove 812 .

[0041] It should be noted that, since the ductility of the membrane layer material is better than that of the fabric layer, when the rolled fabric is subjected to the same tensile force, the fabric layer is easily stretched excessively and causes tearing.

[0042] The present invention utilizes a rubber layer 806 mounted centrally on the rotating drum 803. Initially, the air pressure within the tilting groove 812 is full, causing the rubber layer 806 to expand. As the rolled fabric wraps around the rotating drum 803, the fabric layer adheres to the rubber layer 806. As the sliding sleeve 805 moves relative to the rotating drum 803, the rolled fabric stretches. Simultaneously, the transmission sleeve 808 drives the rotating head 810 to move synchronously. Driven by the connecting rod 811, the rotating head 810 drives the tilting plate 813 downward along the tilting groove 812, extracting the air within the tilting groove 812. This causes the surface of the rubber layer 806 to contract, tightening the rubber layer 806 against the fabric layer, thereby protecting the fabric layer and preventing excessive stretching and tearing.

[0043] The roller pressing pairs 6 of the present invention can be divided into two groups, one before the adjustment assembly 8 and the other after the adjustment assembly 8. The material is pre-rolled by the roller pressing pairs 6, and then rolled by the roller pressing pairs 6 after passing through the adjustment assembly 8, thereby ensuring rolling efficiency.

[0044] See also Figure 2-Figure 10 The lifting assembly 7 includes a guide rail 702 , the guide rail 702 is installed on the inner wall of the base frame 1 , a guide seat 703 is slidably installed on the guide rail 702 , and an adjusting roller 704 is fixedly installed on the guide seat 703 .

[0045] Specifically, a fixed plate 705 is fixedly installed on the inner wall of the base frame 1, and gear one 708 and gear two 709 are rotated on the fixed plate 705, and gear one 708 is engaged with gear two 709. A turbine 707 is coaxially installed on the gear one 708, and a rotating rod 701 is rotatably installed on the base frame 1. A worm 706 is sleeved on the rotating rod 701, and the worm 706 is engaged with the turbine 707. A screw 710 is coaxially installed on the gear two 709, and the screw 710 is connected to the transmission head 711 for transmission, and the transmission head 711 is fixedly installed on the guide seat 703.

[0046] It should be noted that by driving the rotating rod 701, the rotating rod 701 drives the screw 710 to rotate, and through the transmission cooperation between the screw 710 and the transmission head 711, the rotating rod 701 drives the guide seat 703 to slide on the guide rail 702, thereby adjusting the position of the adjustment roller 704, and in this way tensioning the rolled fabric.

[0047] Working principle of the present invention: see Figure 11 The surface material is transported to the roller pair 6 through the top roller 4 and the side roller 3 in turn, and the film material is transported to the roller pair 6 through the bottom roller 5. The film material is rolled onto the surface material under the action of the roller pair 6. After rolling, the material first goes around the adjusting component 8 and is finally sent out through the lifting component 7 and the feeding roller 9.

[0048] This is for the situation where after the film material and the surface material are rolled together, the film layer has wrinkles while the surface material is normal.

[0049] The present invention inserts the rolled fabric between the sliding sleeve 805 and the baffle 817, and after the fabric is wound around the drum 803, it is discharged from between the sliding sleeve 805 and the baffle 817 at the other end. Figure 12 As shown, by adjusting the adjustment knob 815, the pressure roller 816 is controlled to press the fabric, so that the fabric is attached to the sliding sleeve 805. During operation of the equipment, the fabric layer is attached to the rotating drum 803 due to the rolling of the fabric around the rotating drum 803. Under the same conditions, the film layer on the fabric layer has a greater degree of stretching than the fabric layer. Therefore, by rolling the fabric around the rotating drum 803, slight wrinkles on the film layer can be flattened, so that the film layer and the fabric layer are attached.

[0050] In response to the situation where the membrane material has a large degree of wrinkles, the present invention starts the motor 802, which drives the rotating shaft 804 to rotate, and the rotating shaft 804 drives the transmission sleeves 808 on both sides of the rotating shaft 804 to move relative to each other, so that the transmission sleeves 808 drive the sliding sleeves 805 to move away from each other through the rotating plate 809, and the sliding sleeves 805 drive the baffle 817 to move synchronously, so that the rolled fabric wrapped around the rotating drum 803 between the sliding sleeves 805 is stretched, so that the membrane material is flattened by the stretching effect.

[0051] It should be noted that, since the ductility of the membrane layer material is better than that of the fabric layer, when the rolled fabric is subjected to the same tensile force, the fabric layer is easily stretched excessively and causes tearing.

[0052] The present invention installs a rubber layer 806 in the center of the rotating drum 803. Initially, the air pressure within the tilting groove 812 is full, causing the rubber layer 806 to expand. When the rolled fabric wraps around the rotating drum 803, the fabric layer adheres to the rubber layer 806. As the sliding sleeve 805 moves relative to the rotating drum 803, the rolled fabric is stretched. Simultaneously, the transmission sleeve 808 drives the rotating head 810 to move synchronously. Driven by the connecting rod 811, the rotating head 810 drives the tilting plate 813 to slide downward along the tilting groove 812, extracting the air within the tilting groove 812. The surface of the rubber layer 806 contracts, causing it to tighten around the fabric layer, thereby protecting it and preventing excessive stretching and tearing.
