Description

Technical Field

[0001] The invention belongs to the technical field of vacuum insulation panel production equipment and relates to a novel adhesive tape machine, in particular to a novel adhesive tape machine used for applying adhesive tape to vacuum insulation panels. Background Art

[0002] Vacuum insulation panels (VIPs) are highly efficient thermal insulation materials that combine the principles of vacuum insulation with traditional insulation materials. They are manufactured using a glass fiber core and a gas-barrier composite film as the packaging, after vacuum packaging. Because they maximize the vacuum level within the panel and reduce gas convection, they achieve highly efficient insulation. Compared to other materials, VIPs, with their extremely low thermal conductivity, offer advantages such as thin insulation layer thickness, compact size, and light weight while maintaining the same insulation requirements. They are suitable for products requiring high energy efficiency and possess significant technical and economic benefits.

[0003] In the production of vacuum insulation panels, it is necessary to apply tape on both sides of the vacuum insulation panels after folding the edges. In the existing technology, the tape application is generally done manually, which is inefficient and the manual application accuracy is not high, which easily leads to a large number of defective products. Summary of the Invention

[0004] The purpose of the present invention is to solve the above problems in the existing technology and to propose a new type of tape machine that can automatically apply tape to both sides of the vacuum insulation panel after folding the edges.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A new type of tape dispenser includes a mounting frame, a tape wheel installed on the mounting frame, and a suction cup for adsorbing the tape. The tape led out from the tape wheel passes around the suction cup and is adhered to the vacuum insulation panel located below. The mounting frame is provided with a cutting component for cutting the tape between the suction cup and the vacuum insulation panel.

[0007] This new tape conveyor is installed above the conveyor belt, and the vacuum insulation panel is placed on the conveyor belt and transported forward by the conveyor belt. The back of the tape, which is drawn from the tape wheel, passes over the suction cup from back to front, and the adhesive surface of the tape adheres to the upper surface of the vacuum insulation panel. As the vacuum insulation panel is transported forward, the tape is continuously pulled forward and adhered to the vacuum insulation panel, achieving the purpose of automatically adhering the tape to the vacuum insulation panel.

[0008] In the above-mentioned new tape dispenser, the cutting assembly includes a second connecting rod, one end of which is provided with a blade, and the other end is hinged to the mounting frame, and the middle part of the second connecting rod is provided with a driving structure for causing the blade to cut downwards.

[0009] The blade is positioned perpendicular to the length of the second connecting rod. When the second connecting rod is horizontal, the blade extends vertically downward. When the tape needs to be cut, the driving structure rotates the second connecting rod, causing the blade to move downward, contacting and severing the tape between the suction cup and the vacuum insulation panel.

[0010] In the above-mentioned new belt conveyor, the driving structure includes a bracket arranged above the second connecting rod, a first connecting rod whose upper end is hinged to the bracket, and a lifter that lifts the mounting frame up and down relative to the bracket, and the lower end of the first connecting rod is hinged to the middle part of the second connecting rod.

[0011] The lifter drives the mounting bracket up and down, driving the end of the second connecting rod away from the blade to move up and down. When the end of the second connecting rod away from the blade moves upward under the action of the lifter, the blade moves downward, completing the cutting action. Alternatively, the lifter drives the bracket up and down, driving the middle portion of the second connecting rod to move up and down. When the middle portion of the second connecting rod moves downward under the action of the lifter, the blade moves downward, completing the cutting action.

[0012] In the above-mentioned new tape machine, a bottom plate is provided under the mounting frame, and a tape pressing wheel for pressing the tape onto the vacuum insulation panel and an elastic component for keeping the tape pressing wheel pressed onto the vacuum insulation panel at all times are provided on the bottom plate. An adjustment plate is provided on the bottom plate, and the bracket is fixed relative to the adjustment plate.

[0013] The elastic component ensures that the tape pressure wheel remains pressed against the vacuum insulation panel, improving adhesion. The position of the pressure wheel can be adjusted up and down according to the thickness of the vacuum insulation panel, allowing the tape to adhere to panels of varying thicknesses. The portion of the tape between the pressure wheel and the suction cup is the tensioning section, which remains in place when the cutting assembly cuts through the tensioning section.

[0014] In the above-mentioned novel tape conveyor, the lifter includes a cylinder body fixed on the adjustment plate, the bracket is fixed on the cylinder body, and the mounting bracket is fixed on the piston rod of the cylinder body.

[0015] The cylinder body is a pneumatic cylinder or a hydraulic cylinder, preferably a pneumatic cylinder. The cylinder body is inverted, and the piston rod extends from the lower end of the cylinder body. When the piston rod extends, it drives the mounting frame downward; when the piston rod retracts, it drives the mounting frame upward.

[0016] In the above-mentioned new tape machine, the upper end of the suction cup is hinged on the mounting frame, and the rotation center of the suction cup around the mounting frame is parallel to the axis of the tape wheel. The suction cup has an adsorption surface that contacts the tape, and the adsorption surface is provided with a plurality of suction holes.

[0017] The suction cup is hollow, with an air inlet and an air vent on the side opposite the suction surface. The suction port is connected to an external vacuum pump. The air vent prevents the suction cup from holding the tape too tightly, ensuring that the tape moves with the vacuum insulation panel. To achieve a better fit, the suction surface is cylindrical or arc-shaped.

[0018] As the mounting frame moves up and down, the suction cup has two states: in contact with the vacuum insulation panel or not in contact with the vacuum insulation panel.

[0019] In the above-mentioned new tape machine, the mounting frame is provided with a baffle for preventing the tape from falling off the suction cup. The side of the baffle facing the suction cup has an anti-stick coating. The mounting frame is provided with a driving structure for driving the baffle to move to the bottom of the suction cup when the mounting frame rises.

[0020] When the mounting frame rises, the drive mechanism moves the baffle below the suction cup. The side of the baffle facing the suction cup moves to the underside of the suction surface and faces the suction surface. The tape is compressed between the suction surface and the side of the baffle facing the suction cup, preventing it from falling off the suction cup. When the mounting frame descends, the baffle disengages from the suction cup and moves behind it. The side of the baffle facing the suction cup is a cylindrical or arc-shaped surface.

[0021] In the above-mentioned new belt conveyor, the driving structure includes a third connecting rod hinged on the bracket and extending downward and a fourth connecting rod hinged at the lower end of the third connecting rod. The lower end of the fourth connecting rod is fixedly connected to a first rotating shaft parallel to the belt wheel. The first rotating shaft is rotatably arranged in the mounting frame. A fifth connecting rod is fixedly connected to the first rotating shaft, and the baffle is fixedly connected to the fifth connecting rod.

[0022] The rotation center line of the fourth link rotating around the third link is parallel to the first rotating shaft, and the first rotating shaft is parallel to the belt wheel. When the mounting frame is raised and lowered, the up and down movement of the mounting frame is converted into the swing of the fifth link around the first rotating shaft, thereby controlling the movement of the baffle.

[0023] In the novel tape dispenser, a second rotating shaft coaxial with the first rotating shaft is rotatably mounted on the mounting frame. The first and second rotating shafts are fixedly connected by a connecting rod. A sixth connecting rod is fixedly connected to the second rotating shaft, and the baffle is fixedly connected to the sixth connecting rod. One end of the baffle is fixedly connected to the fifth connecting rod, and the other end is fixedly connected to the sixth connecting rod, thereby improving the structural stability of the baffle.

[0024] In the above-mentioned novel tape dispenser, an opening is provided on the bottom plate, and the tape pressing wheel is provided in the opening; when the suction cup contacts the vacuum insulation panel, the suction cup is located in the opening.

[0025] In the aforementioned new tape dispenser, the elastic assembly comprises two supports fixed to the base plate and an elastic member within the supports for pressing the tape roller downward. Vertically extending slots are provided on opposing sides of the two supports. The ends of a support shaft supporting the tape roller extend into the slots, with the lower end of the elastic member acting on the support shaft. The elastic member, which can be a spring, presses against the support shaft under its elastic force, thereby keeping the tape roller pressed against the vacuum insulation panel.

[0026] Compared with the existing technology, this new tape machine has the following advantages:

[0027] The new tape machine can automatically apply tape to both sides of the vacuum insulation panel after folding, replacing the manual operation method in the existing technology, so as to achieve the purpose of improving the quality of the vacuum insulation panel, saving manpower, improving efficiency and reducing costs.

DETAILED DESCRIPTION

[0035] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0036] like Figure 1 The new type of belt conveyor shown includes an adjustment plate 13 installed on one side of the conveyor belt. The bottom of the adjustment plate 13 is a bottom plate 10 arranged parallel to the top of the conveyor belt. The bottom plate 10 has an opening 101, and a belt pressure wheel 20 is set at the opening 101. The bottom plate 10 is also provided with an elastic component for keeping the belt pressure wheel 20 pressed against the vacuum insulation panel at all times.

[0037] like Figure 6 As shown, the elastic assembly includes two supports 60 fixed to the base plate 10 and an elastic member 61 disposed within the supports 60 for pressing down the tape pressure roller 20. Vertically extending slots 601 are provided on opposite sides of the two supports 60. The ends of the support shaft 21 supporting the tape pressure roller 20 extend into the slots 601, respectively. The lower end of the elastic member 61 acts on the support shaft 21. The elastic member 61 may be a spring, the lower end of which acts on the support shaft 21, thereby keeping the tape pressure roller 20 pressed against the vacuum insulation panel.

[0038] like Figure 1 、 Figure 3 and Figure 4 As shown, a lifter is fixed on the adjustment plate 13. The lifter is a cylinder, including a cylinder body 14 and a piston rod 15, and the piston rod 15 extends from the lower end of the cylinder body 14. Figure 3 and Figure 4 As shown, a mounting bracket 40 is fixed to the lower end of the piston rod 15. When the piston rod 15 is extended or retracted, it drives the mounting bracket 40 up and down. The mounting bracket 40 is composed of two parallel side panels, with four parallel, horizontally extending connecting shafts fixed between the two side panels. The four connecting shafts connect the two side panels together.

[0039] like Figure 1 and Figure 2 As shown, tape pulleys 30 are mounted above the mounting frame 40, with their axes parallel to the axes of the connecting shafts. Two of the connecting shafts are fitted with rotatable tape rollers, while the other two connecting shafts serve as hinged axes. The tape drawn from the tape pulleys 30 passes sequentially around the upper and lower tape rollers, moving downward.

[0040] like Figure 3 and Figure 4As shown, a suction cup 50 is mounted on the bottommost connecting shaft and can swing around the connecting shaft. The suction cup 50 has a suction surface 51 that contacts the tape. The suction surface 51 is cylindrical or arc-shaped and is provided with a plurality of suction holes. The suction cup 50 is hollow inside, and an air intake and an air inlet are provided on the side opposite the suction surface 51. The air intake is connected to an external vacuum device. The air inlet effectively prevents the suction cup 50 from holding the tape too tightly, ensuring that the tape moves with the vacuum insulation panel. As the mounting bracket 40 rises and falls, the suction cup 50 has two states: in contact with the vacuum insulation panel and out of contact.

[0041] The tape led out from the tape wheel 30 passes through the upper tape roller, the lower tape roller and the suction cup 50 from top to bottom and extends to the bottom of the tape pressure wheel 20. The part of the tape between the suction cup 50 and the tape pressure wheel 20 is the tensioning part. After the tape is pasted on a vacuum insulation board, the tape needs to be cut. In order to realize automatic cutting of the tape, a cutting component for cutting the tape along the tensioning part is provided on the mounting frame 40.

[0042] like Figure 3 As shown, a bracket 11 is fixed on the cylinder 14, and a first connecting rod 12 extending downward is hinged on the bracket 11. The rotation center line of the first connecting rod 12 rotating around the bracket 11 is parallel to the axis of the tape wheel 30. Figure 3 As shown, the cutting assembly includes a second connecting rod 41 with one end sleeved on one of the connecting shafts and a blade 42 provided at the other end of the second connecting rod 41. The middle part of the second connecting rod 41 is hinged to the lower end of the first connecting rod 12. When the piston rod 15 contracts upward, it drives the mounting frame 40 to move upward, thereby driving the end of the second connecting rod 41 sleeved on the connecting shaft to move upward, realizing the swing of the first connecting rod 12, and the blade moves downward to cut the tensioning part of the tape.

[0043] When the mounting bracket 40 is lifted upward, the suction cup 50 moves upward together. In order to prevent the adhesive tape from falling off the suction cup 50, Figure 2 and Figure 4 As shown, a baffle 43 is provided on the mounting frame 40 for preventing the tape from falling off the suction cup 50, and an anti-stick coating is provided on the side 44 of the baffle facing the suction cup. The mounting frame 40 is provided with a driving structure for driving the baffle 43 to move to the rear of the suction cup 50 when the mounting frame 40 rises.

[0044] When the mounting frame 40 rises, the driving mechanism causes the baffle 43 to move below the suction cup 50. At this time, the side 44 of the baffle facing the suction cup moves to the lower side of the suction surface 51 and is positioned opposite the suction surface 51. The adhesive tape is pressed between the suction surface 51 and the side 44 of the baffle facing the suction cup, preventing the tape from falling off the suction cup 50. When the mounting frame 40 descends, the baffle 43 disengages from the suction cup 50.

[0045] like Figure 4 and Figure 5 As shown, the driving structure includes a third connecting rod 16 hinged on the bracket 11 and extending downward, and a fourth connecting rod 17 hinged at the lower end of the third connecting rod 16. The lower end of the fourth connecting rod 17 is fixedly connected to a first rotating shaft 18 parallel to the tape pulley 30. The first rotating shaft 18 is rotatably arranged in the mounting frame 40. A fifth connecting rod 19 is fixedly connected to the first rotating shaft 18, and the baffle 43 is fixedly connected to the fifth connecting rod 19.

[0046] The rotation center line of the fourth connecting rod 17 rotating around the third connecting rod 16 is parallel to the first rotating shaft 18, and the first rotating shaft 18 is parallel to the tape wheel 30. When the mounting bracket 40 is raised and lowered, the up and down movement of the mounting bracket 40 is converted into the swing of the fifth connecting rod 19 around the first rotating shaft 18, thereby controlling the movement of the baffle 43.

[0047] like Figure 5 As shown, a second rotating shaft 181 coaxial with the first rotating shaft 18 is rotatably provided on the mounting frame 40. The first rotating shaft 18 and the second rotating shaft 181 are fixedly connected by a connecting rod 182. A sixth connecting rod 191 is fixedly connected to the second rotating shaft 181, and the baffle 43 is fixedly connected to the sixth connecting rod 191. One end of the baffle 43 is fixedly connected to the fifth connecting rod 19, and the other end is fixedly connected to the sixth connecting rod 191, thereby improving the structural stability of the baffle 43.

[0048] During operation, the vacuum insulation panel is transported to the bottom of the new tape machine via the conveyor belt. The piston rod 15 of the cylinder extends, driving the mounting frame 40 to move downward. The cylindrical surface of the suction cup 50 contacts the packaging bag of the vacuum insulation panel. Under the pressure of the suction cup 50, the tape is adhered to the packaging bag of the vacuum insulation panel.

[0049] When the end of the vacuum insulation panel is separated from the suction cup 50, the piston rod 15 of the cylinder contracts, driving the mounting frame 40 to move upward, causing the second connecting rod 41 to rotate around one of the connecting axes, driving the blade 42 to rotate downward. At this time, the tape is attached to the vacuum insulation panel and is adsorbed by the suction cup 50. The tape is in a taut state. The downward swinging blade 42 cuts the tape. At the same time, the fourth connecting rod 17 rotates upward around the hinge with the third connecting rod 16. The fourth connecting rod 17 drives the connecting rod 182, the fifth connecting rod 19, and the sixth connecting rod 191 to rotate, thereby driving the baffle 43 to move below the suction cup 50, so that the tape is closer to the suction cup 50, making it easier for the suction cup 50 to adsorb the cut tape and prevent the tape from falling.

[0050] The specific embodiments described herein are merely illustrative of the spirit of the present invention.
