Description

Technical Field

[0001] The invention relates to the technical field of fully automatic die-cutting for self-adhesive labels, in particular to a fully automatic die-cutting machine for self-adhesive labels and a die-cutting process thereof. Background Art

[0002] Self-adhesive trademark die-cutting machines, also known as die-cutting machines or CNC die-cutting machines, are widely used. Compared to previous drawbar die-cutting machines and the most primitive punch presses, these machines are faster and feature a full touchscreen interface for easier operation, resulting in higher-precision products and improved efficiency. High-precision die-cutting, material dragging, and slicing are computer-controlled using a flat press. Three photoelectric sensors precisely track the edges and longitudinal direction of the printed label. Die-cutting, laminating, waste collection, slicing, or automatic labeling are all completed in one operation. They are ideal for die-cutting paper self-adhesive labels, polyester film labels, and laser anti-counterfeiting labels. This machine is an ideal companion to flexographic printing presses, continuous screen printers, gravure printing presses, and anti-counterfeiting label embossing machines, making it an ideal and efficient solution for any trademark printing plant.

[0003] The existing self-adhesive die-cutting machine uses a reciprocating mechanism to carry the tool to move up and down to achieve die-cutting of the self-adhesive. During the die-cutting process, the tool moves up and down continuously, and the edges of the self-adhesive itself will stick after cutting, thus sticking to the inside of the tool, making it inconvenient to perform material discharge work. Secondly, the tool has poor buffering effect when moving up and down quickly, so it is easy to collide and vibrate with the transportation equipment carrying the self-adhesive, resulting in deformation of the shape of the self-adhesive and deviation in positioning, which leads to the problem of cutting out waste.

[0004] Based on this, the present invention designs a fully automatic die-cutting machine for self-adhesive stickers and its die-cutting process to solve the above problems. Summary of the Invention

[0005] The object of the present invention is to provide a fully automatic die-cutting machine for self-adhesive stickers and its die-cutting process, so as to solve the problem proposed in the above background technology that the existing self-adhesive sticker die-cutting machine uses a reciprocating mechanism to carry a cutter to move up and down to achieve die-cutting of the self-adhesive stickers. During the die-cutting process, the cutter continuously moves up and down, and the edges of the self-adhesive stickers will stick after being cut, thus sticking to the inside of the cutter, making it inconvenient to perform the material discharge work. Secondly, the cutter has a poor buffering effect when moving up and down quickly, so it is easy to collide and vibrate with the transportation equipment carrying the self-adhesive stickers, thereby causing deformation of the shape of the self-adhesive stickers, resulting in positioning deviation, and thus leading to the problem of cutting out waste.

[0012] As a further solution of the present invention, the motor adopts a reduction motor that can enable the device to obtain greater torque.

[0013] As a further embodiment of the present invention, a fully automatic die-cutting process for self-adhesive stickers is provided. The specific steps of the fully automatic die-cutting process for self-adhesive stickers are as follows:

[0014] Step 1: Spread out the self-adhesive strips or patches to be die-cut and place them on a movable die-cutting platform, so that the die-cutting platform carries the self-adhesive strips for transportation;

[0015] Step 2: Start the motor of the equipment, so that the ring barrel drives the undulating track to revolve, thereby causing the force rod to move up and down, thereby causing the reciprocating barrel to move up and down along the fixed axis, thereby causing the tool holder to move up and down with the tool to cut the self-adhesive on the die-cutting platform;

[0016] Step 3: When the reciprocating barrel moves up and down along the fixed axis, the negative pressure in the tool holder is switched back and forth to absorb and release the die-cutting material, thereby completing the material removal process;

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention drives the power shaft to rotate by a motor to rotate the power gear, which drives the ring barrel to rotate on the one hand and fixes the ring barrel on the other hand. Secondly, the undulating track on the ring barrel drives the reciprocating barrel at the outer end of the fixed shaft to move, so that the reciprocating barrel drives the tool at the lower end to perform die-cutting. Secondly, the curvature of the undulating track is smoothly set, so that when the reciprocating barrel is running, a speed reduction buffering effect occurs at the highest point and the lowest point, so that the reciprocating barrel can be buffered during operation, avoiding large vibrations of the equipment, causing vibrations of the self-adhesive label, causing positioning failure of the self-adhesive label, and causing poor die-cutting accuracy.

[0020] 2. The present invention increases the internal cavity of the reciprocating barrel by descending, thereby generating a negative pressure. When the reciprocating barrel moves to the lowest end, the pressure relief valve stem contacts the die-cut adhesive, thereby causing the pressure relief valve stem to drive the sealing plate to overcome the resistance of the sealing spring and move upward, thereby causing the air guide hole to break away from the contact with the sealing ring plate, thereby adsorbing the adhesive die-cut material onto the tool and the inner wall of the tool holder through the air pressure inside the reciprocating barrel, and then transferring a part of the negative pressure inside the reciprocating barrel to the inside of the tool holder during the rising process of the reciprocating barrel. When the reciprocating barrel rises to the highest end, positive air pressure is generated inside, thereby causing the pressure relief valve stem to overcome the elastic force of the unsealing spring, causing the pressure relief valve stem to move downward, thereby pushing the die-cut material at the lower end out of the tool holder, thereby completing the material unloading process and avoiding the problem of the adhesive sticking and inconvenience in transportation.

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 Figure 1-5 The present invention provides a technical solution: a fully automatic die-cutting machine for self-adhesive labels, comprising a motor 9 and a top plate bracket 10, a fixed shaft 11 fixedly provided in the center of the top plate bracket 10, a reciprocating barrel 12 vertically slidingly provided on the outer wall of the fixed shaft 11, a plurality of power shafts 13 rotating in a circular array around the top plate bracket 10, two power gears 14 fixedly provided on each power shaft 13, a ring barrel 15 coaxial with the reciprocating barrel 12 provided on the outer side thereof, and a limiting ring plate for being clamped on the outer side of the two power gears 14 fixedly provided on the upper and lower end surfaces of the ring barrel 15 16. Two ring gear rings 17 are coaxially fixed on the ring barrel 15 and mesh with the upper and lower power gears 14 respectively. The side wall of the ring barrel 15 is fixed with an undulating track 18 connected in the first place. A force rod 19 is fixed on the outer wall of the reciprocating barrel 12. The outer end of the force rod 19 is slidably set inside the undulating track 18. The upper end of the power shaft 13 is connected to the output shaft of the motor 9 through the gear set 20. The motor 9 is fixed to the top plate bracket 10 through a bracket. The lower end of the reciprocating barrel 12 is provided with a die-cutting mechanism, and the lower end of the die-cutting mechanism is provided with a die-cutting carrier for transporting existing self-adhesive patches.

[0031] Before using the present invention, the device must be assembled. Figure 1 As shown, from Figure 1 Looking down, it is the upper end of the device. Figure 1 The left end of the device is viewed from left to right, and the device orientation will be used for description hereafter without further explanation.

[0032] When the present invention is used, the motor 9 drives the gear set 20 to rotate on the top plate bracket 10, thereby driving the power shaft 13 to rotate on the top plate bracket 10, the power shaft 13 rotates to drive the power gear 14 to rotate, the power gear 14 rotates to drive the ring gear 17 to rotate, and the ring gear 17 rotates to drive the ring barrel 15 to rotate (such as Figure 1 As shown, the two power gears 14 on the power shaft 13 can, on the one hand, drive the two ring gears 17 to rotate more balanced, and on the other hand, by clamping the limiting ring plates 16 at the upper and lower ends of the ring barrel 15 on the outside of the two power gears 14, the ring barrel 15 can be supported to a certain extent, and the annular power gear 14 can clamp the ring barrel 15 in the middle, so that the ring barrel 15 can be stably fixed), driving the ring barrel 15 to rotate and drive the undulating track 18 to revolve, and secondly, the reciprocating barrel 12 is axially slidably set on the outer wall of the fixed fixed shaft 11, so that the reciprocating barrel 12 cannot rotate on its own, so that the force rod 19 at the outer end of the reciprocating barrel 12 cannot rotate on its own, And it can only reciprocate up and down with the revolution of the undulating track 18 (the undulating track 18 connected in the first place makes the reciprocating barrel 12 reciprocate vertically along the outer wall of the fixed shaft 11, wherein the turning angle slope of the undulating track 18 can be set very slowly, so that when the reciprocating barrel 12 reaches the extreme position, its vertical speed slowly decreases, thereby having a certain buffering effect, thereby avoiding large impact and vibration of the equipment, which may cause deviation in the positioning of the self-adhesive sticker, thereby causing the problem of offset of the self-adhesive sticker). The reciprocating barrel 12 moves up and down, thereby making the tool holder 25 move up and down, thereby completing the die-cutting function of the self-adhesive sticker on the die-cutting carrier of the existing transport self-adhesive sticker;

[0033] The present invention drives the power shaft 13 to rotate by the motor 9 so that the power gear 14 rotates, driving the ring barrel 15 to rotate on the one hand and fixing the ring barrel 15 on the other hand, and then drives the reciprocating barrel 12 at the outer end of the fixed shaft 11 to move through the undulating track 18 on the ring barrel 15, so that the reciprocating barrel 12 drives the lower end tool to perform die-cutting. Secondly, the curvature of the undulating track 18 is smoothly set, so that when the reciprocating barrel 12 is running, a speed reduction buffering effect occurs at the highest point and the lowest point, so that the reciprocating barrel 12 can be buffered during operation, avoiding large vibration of the equipment, causing vibration of the self-adhesive label, causing positioning failure of the self-adhesive label, and causing poor die-cutting accuracy.

[0034] As a further solution of the present invention, the die-cutting mechanism includes a tool holder 25 fixedly arranged on the lower end surface of the reciprocating barrel 12, and a detachable existing tool is provided on the tool holder 25. A sealing ring plate 26 is fixedly provided inside the cavity at the lower end of the reciprocating barrel 12, and a sealing plate 27 is provided on the upper end of the sealing ring plate 26 and is vertically slidably arranged on the inner wall of the cavity of the reciprocating barrel 12. An air guide hole 28 for air guide is provided on the contact surface between the sealing plate 27 and the sealing ring plate 26; an adsorption switching device for adsorption when the tool is die-cutting the self-adhesive sticker is provided above the sealing plate 27; the adsorption switching device includes a fixed bracket 29 fixedly provided on the inner wall of the cavity at the lower end of the reciprocating barrel 12 above the sealing plate 27, and a fixed bracket 29 fixed on the inner wall of the cavity at the lower end of the reciprocating barrel 12 A pressure relief valve rod 30 is provided in the central limited sliding position of the bracket 29. The pressure relief valve rod 30 passes through the sealing plate 27 and is slidably connected to the sealing plate 27. A flat pressure groove 31 with a width greater than the thickness of the sealing plate 27 is provided on the pressure relief valve rod 30. A sealing spring 32 is fixedly provided between the sealing plate 27 and the fixed bracket 29. An unsealing spring 33 is fixedly provided between the pressure relief valve rod 30 and the sealing plate 27 and is sleeved on the outside of the pressure relief valve rod 30. A discharge rod 34 is fixedly provided at the lower end 4 of the fixed shaft 11 for squeezing the pressure relief valve rod 30 downward to move the flat pressure groove 31 through the sealing plate 27 to balance the air pressure. A material receiving device is provided at the lower end of the tool holder 25 for receiving the material after the adsorption switching device pushes out the cut material.

[0035] When the device is used, there is a displacement difference between the reciprocating barrel 12 and the power shaft 13 when the reciprocating barrel 12 descends, and the lower end position of the power shaft 13 is fixed, and the reciprocating barrel 12 descends (such as Figure 2 and 3As shown), the internal cavity of the reciprocating barrel 12 increases, thereby generating a negative pressure. At the same time, the fixed bracket 29 moves downward with the reciprocating barrel 12, so that the sealing spring 32 always presses the sealing plate 27 to coincide with the sealing ring plate 26, so that the air guide hole 28 is closed by the sealing ring plate 26, so that the internal air pressure of the reciprocating barrel 12 is not small. When the reciprocating barrel 12 drops to the lowest end and the tool at the lower end of the tool holder 25 die-cuts the self-adhesive, the reciprocating barrel 12 runs to the lowest end, so that the pressure relief valve stem 30 contacts the die-cut self-adhesive, so that the pressure relief valve stem 30 drives the sealing plate 27 to overcome the resistance of the sealing spring 32 and move upward, so that the air guide hole 28 is separated from the contact with the sealing ring plate 26, so that the self-adhesive is not The adhesive die-cut material is adsorbed onto the inner wall of the tool and the tool holder 25 (during the ascending process of the reciprocating barrel 12, a part of the negative pressure inside the reciprocating barrel 12 is transferred to the inside of the tool holder 25, so that the sealing plate 27 rebounds again, thereby pushing one end of the adhesive die-cut material outward and preventing it from falling), thereby completing the first part of the unloading process and separating from the adhesive. As the reciprocating barrel 12 moves upward, the internal negative pressure slowly decreases, and a part of the negative pressure is used during the descending process. When the reciprocating barrel 12 rises to the uppermost end, positive air pressure is generated inside, thereby causing the pressure relief valve stem 30 to overcome the elastic force of the unsealing spring 33, causing the pressure relief valve stem 30 to move downward, thereby pushing the die-cut material at the lower end out of the tool holder 25 and falling into the material receiving device at the lower end, thereby completing the second step of the unloading process;

[0036] The present invention increases the internal cavity of the reciprocating barrel 12 by descending the reciprocating barrel 12, thereby generating a negative pressure. The reciprocating barrel 12 runs to the lowest end, so that the pressure relief valve stem 30 contacts the die-cut adhesive, so that the pressure relief valve stem 30 drives the sealing plate 27 to overcome the resistance of the sealing spring 32 and move upward, so that the air guide hole 28 is separated from the contact with the sealing ring plate 26, so that the adhesive die-cut material is adsorbed onto the tool and the inner wall of the tool holder 25 by the air pressure inside the reciprocating barrel 12, and then, due to the negative pressure inside the reciprocating barrel 12 during the rising process of the reciprocating barrel 12, a part of it is transferred to the inside of the tool holder 25. When the reciprocating barrel 12 rises to the highest end, positive air pressure is generated inside, so that the pressure relief valve stem 30 overcomes the elastic force of the unsealing spring 33, so that the pressure relief valve stem 30 moves downward, thereby pushing the die-cut material at the lower end out of the tool holder 25, thereby completing the material unloading process, avoiding the problem of the adhesive sticking and inconvenience in transportation.

[0037] As a further solution of the present invention, the material receiving device includes a receiving hopper 37 with an inclined bottom surface, and the two side walls of the upper end of the receiving hopper 37 are horizontally provided with a through long circular groove 38, and two parallel track rods 39 are respectively provided in the long circular groove 38, one of the track rods 39 is set at the end of the long circular groove 38, and the other track rod 39 is horizontally slidably set on the inner wall of the long circular groove 38, and the ends of the two track rods 39 on the same side are respectively rotatably provided with a short connecting rod 40 and a long connecting rod 41, the short connecting rod 40 and the long connecting rod 41 are hinged to each other, and the short connecting rod 40 and the long connecting rod 41 form an isosceles triangle with the hinge points of the two track rods 39, and the lower end of the long connecting rod 41 is rotatably set on the side wall of the top plate bracket 10 through an L bracket. A traverse mechanism for keeping the receiving hopper 37 horizontally moving up and down is provided between the upper end of each track rod 39 and the tool holder 25; the traverse mechanism includes a clamping rod 43 and a pressure rod 44 which are rotatably provided on the track rod 39 and are arranged in an inverted symmetrical manner with the short connecting rod 40 and the long connecting rod 41. The ends of the clamping rod 43 and the pressure rod 44 are hinged to each other, and the upper end of the pressure rod 44 is rotatably provided at the lower end of the tool holder 25 through a pin bracket. The clamping rod 43 and the pressure rod 44 form an isosceles triangle with the rotating hinge points of the two track rods 39; a baffle 46 for preventing the cut material from sliding down after the self-adhesive die-cutting is fixed at the lower end of the hinge axis of the clamping rod 43 and the pressure rod 44, and the lower end of the baffle 46 is in contact with the inner wall of the bottom end of the receiving hopper 37;

[0038] like Figure 1 and 2 As shown, the tool holder 25 descends, causing the acute angle between the clamping rod 43 and the pressure rod 44 to increase, and the distal track rod 39 is located at the outer end of the long circular groove 38, thereby increasing the distance between the two track rods 39, and the acute angle of the short connecting rod 40 and the long connecting rod 41 at the outer end of the track rod 39 also increases accordingly, thereby causing the hopper 37 to tend to move downward toward the front end of the equipment, and always keeping the upper end surface horizontal. Secondly, the acute angle between the clamping rod 43 and the pressure rod 44 increases, causing the hinge point between the two to rise (relative to the bottom surface of the hopper 37), thereby causing the baffle 46 to rise, so that the hopper 3 moves forward to the outer end of the existing die-cutting platform for transporting self-adhesive patches before unloading, thereby completing the process of precise unloading and receiving.

[0039] As a further solution of the present invention, the motor 9 adopts a reduction motor that can enable the device to obtain greater torque.

[0040] As a further embodiment of the present invention, a fully automatic die-cutting process for self-adhesive stickers is provided. The specific steps of the fully automatic die-cutting process for self-adhesive stickers are as follows:

[0041] Step 1: Spread out the self-adhesive strips or patches to be die-cut and place them on a movable die-cutting platform, so that the die-cutting platform carries the self-adhesive strips for transportation;

[0042] Step 2: Start the motor 9 of the device, so that the ring barrel 15 drives the undulating track 18 to revolve, thereby causing the force rod 19 to move up and down, thereby causing the reciprocating barrel 12 to move up and down along the fixed axis 11, thereby causing the tool holder 25 to carry the tool to move up and down to cut the self-adhesive label on the die-cutting platform;

[0043] Step 3: When the reciprocating barrel 12 moves up and down along the fixed axis 11, the negative pressure in the tool holder 25 is switched back and forth to absorb and release the die-cutting material, thereby completing the material removal process;

[0044] Step 4: Next, the tool holder 25 drives the receiving hopper 37 to maintain horizontality and perform tilted movement horizontally and up and down, accurately receiving the die-cutting material adsorbed by the lower end of the tool holder 25 to complete the die-cutting process.
