Description

Technical Field

[0001] The utility model relates to the technical field of printing and processing equipment, in particular to a pasting, tearing and drawing device suitable for printing and processing. Background Art

[0002] In the packaging and printing industry, the application of a folder-gluer is the final step in the box production process. It folds and glues the printed and die-cut cardboard sheets. This machine replaces manual gluing, reducing labor costs and improving efficiency. A folder-gluer consists of a paper feeder, pre-folding unit, bottom hook, forming unit, and box pressing unit. Applying a tear cord to a box is a specialized process in the packaging industry. This process involves attaching an easy-to-tear cord or tape to the box, making it easier for consumers to open. This process is particularly suitable for industries such as food, pharmaceuticals, and cosmetics, providing a more convenient opening experience while also enhancing product appeal and user experience.

[0003] The existing tear line pasting process is usually completed manually after the paper box comes out of the box gluing machine production line. However, when facing large-scale production, the manual tear line pasting method will significantly reduce the overall production efficiency and lead to increased labor costs. In addition, manual operation cannot ensure that the position, strength and angle of the tear line are completely consistent each time, which easily leads to unstable tear line pasting effect.

[0004] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a tearing wire drawing device suitable for printing processing, comprising a fixed plate mounted on a conveyor belt, a preparation plate provided at the upper end of the fixed plate, an assembly roller provided near the top end of the preparation plate, a tearing wire coil mounted on the assembly roller, and a wire tensioning pulley assembly further provided on the preparation plate;

[0007] The fixed plate is provided with a shell, and the shell is rotatably provided on the fixed plate through a rotating shaft. The rotating shaft is provided with a wire wheel inside the shell, and the shell is also provided with a rotatable first wire pressing wheel;

[0008] The fixed plate is provided with a column plate, and a cutter is installed on the side of the column plate facing the first pressing wheel, wherein the tearing wire is led out from the tearing wire reel and passes through the wire tensioning pulley assembly, the guide wheel and the first pressing wheel in sequence, and the guide wheel, the first pressing wheel and the cutter are arranged in front and back in sequence;

[0009] The fixed plate is also provided with a pushing mechanism installed obliquely toward the shell, which is connected to the shell and causes the shell to rotate around the rotating shaft when pushing the shell, so that the first pressing wheel presses the tear line onto the product.

[0010] As a further solution of the present invention: a built-in plate is provided in the shell, the side of the built-in plate facing the cutter has a jaw, the first crimping wheel is rotatably connected to the jaw, and a spring is connected between the built-in plate and the shell.

[0011] As a further solution of the utility model: the wire pulley assembly includes a mounting strip arranged on a preparation plate, one end of the mounting strip is extended to one side and is provided with a guide pulley, the preparation plate is provided with a slide rail, and the slide rail is slidably connected to a movable pulley;

[0012] Among them, the heights on the configuration plate from high to low are the assembly roller, the guide pulley and the movable pulley;

[0013] The guide pulley, movable pulley and wire pulley are arranged in a triangular position relationship;

[0014] The tearing wire is sequentially wound around the movable pulley and the guide pulley and then supported by the guide pulley.

[0015] As a further solution of the present invention: the guide wheel is provided with two convex rings, and a limited space is formed between the two convex rings.

[0016] As a further solution of the present invention: a second pressing wheel is provided on the fixed plate, and the second pressing wheel is located on the side of the cutter away from the first pressing wheel.

[0017] As a further solution of the present invention: the height of the cutter is lower than the maximum rising height of the first crimping wheel.

[0018] As a further solution of the present invention: a connecting shaft is provided at the upper end of the shell, and the pushing mechanism is connected to the connecting shaft.

[0019] Compared with the prior art, the beneficial effects of the present technical solution are as follows: the pushing mechanism pushes the shell shaft to rotate as the axis, so that the thread end of the tearing line of the first pressing wheel is pressed and adhered to the product. The moment the first pressing wheel presses the thread end of the tearing line onto the product, the tearing line will be tightened, and the tightening force is transmitted to the movable pulley and converted into elastic force to make the movable pulley slide upward, and the tearing line is in a relaxed state so that a section of the tearing line can be attached to the moving product. At the same time, the movable pulley slides down to tighten the tearing line and take out the tearing line of the required length from the tearing line reel. Then the pushing mechanism performs the retraction action, and the first pressing wheel disengages from the tearing line so that the connection between the tearing line and the product will bounce upward, and collide with the cutter when bouncing up and break. Moreover, the thread end of the cut tearing line naturally falls down and contacts the passing product, which is convenient for the next pressing of the first pressing wheel.

[0020] From the above, it can be seen that the utility model can realize the operation of pasting, tearing and pulling the line of the products being conveyed on the existing folder-gluing machine production line, so as to replace the manual operation, improve the production efficiency, save labor costs, and the short pressing stroke makes it possible to adapt to the fast transmission speed of the conveyor belt;

[0021] Among them, since the first pressing wheel rotates downward and upward with the rotating shaft as the axis following the shell, the first pressing wheel will have a forward buckling effect when it moves downward to press the tear line, thereby ensuring that the first pressing wheel can drive the end of the tear line when pressing down, so as to avoid the inability to press the end of the tear line when moving straight up and down.

[0022] When the first crimping wheel continuously presses and tears the product, the first crimping wheel will collide with the conveyor belt continuously at a very high speed. At this time, the first crimping wheel is installed using an internal plate, and the vibration force generated during the collision is absorbed by the spring between the internal plate and the shell to avoid continuous high-speed collisions that may cause the structure of the first crimping wheel to become loose easily, thereby increasing the service life of the first crimping wheel.

[0023] Additional aspects and advantages of the present invention will be given in part in the following description and will become apparent from the following description or learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-4 , a tearing wire drawing device suitable for printing processing, comprising a fixed plate 1 mounted on a conveyor belt, a preparation plate 2 is provided on the upper end of the fixed plate 1, an assembly roller 3 is provided near the top of the preparation plate 2, a tearing wire roll 4 is mounted on the assembly roller 3, and a wire tensioning pulley assembly 5 is further provided on the preparation plate 2, the wire tensioning pulley assembly 5 comprises a mounting strip 501 arranged on the preparation plate 2, one end of the mounting strip 501 is extended to one side and a guide pulley 502 is provided, the preparation plate 2 is provided with a slide rail 503, and a movable pulley 504 is slidably connected to the slide rail 503, wherein the heights on the preparation plate 2 are, from high to low, the assembly roller 3, the guide pulley 502 and the movable pulley 504;

[0033] A housing 6 is provided on the fixed plate 1. The housing 6 is rotatably provided on the fixed plate 1 via a rotating shaft 7. A guide pulley 8 is provided on the rotating shaft 7 and is located inside the housing 6. A rotatable first pressing wheel 9 is also provided inside the housing 6. The guide pulley 502, the movable pulley 504, and the guide pulley 8 are arranged in a triangular position relationship. The tear wire is sequentially wound around the movable pulley 504 and the guide pulley 502 and then supported by the guide pulley 8.

[0034] A column plate 10 is provided on the fixed plate 1, and a cutter 1001 is installed on the side of the column plate 10 facing the first creasing wheel 9. The tearing wire is drawn out from the tearing wire reel 4 and passes through the wire tensioning pulley assembly 5, the guide wheel 8 and the first creasing wheel 9 in sequence, and the guide wheel 8, the first creasing wheel 9 and the cutter 1001 are arranged in front and back in sequence;

[0035] The fixed plate 1 is also provided with a pushing mechanism 11 installed obliquely toward the shell 6. The pushing mechanism 11 is connected to the shell 6, and when the shell 6 is pushed, the shell 6 rotates around the rotating shaft 7 as the axis, so that the first pressing wheel 9 presses the tear line onto the product.

[0036] Specifically, when the product moves to the bottom of the first pressing wheel 9 through the conveyor belt on the box gluing machine, the pushing mechanism 11 (such as a cylinder) pushes the shell 6, and the shell 6 rotates with the rotating shaft 7 as the axis. As the shell 6 rotates, the first pressing wheel 9 presses the end of the tear line onto the product during the downward pressing process, so that the end of the tear line sticks to the product. The tear line is tightened at the moment when the first pressing wheel 9 presses the end of the tear line onto the product, and the tightening force is transmitted to the movable pulley 504 through the guide pulley 502. The tightening force is converted into elastic force and applied to the movable pulley 504, so that the movable pulley 504 slides upward on the slide rail 503. At this time, the tear line is in a relaxed state, so that the first pressing wheel 9 presses the tear line onto the product. In the process of the product being driven by the conveyor belt, a section of the tear line can be attached to the moving product. At the same time, in this process, the movable pulley 504 uses its own gravity to slide on the slide rail 503. The first pressing wheel 9 is pressed down on the product, and the first pressing wheel 9 is pressed down on the product, so that the first pressing wheel 9 can press the product to move forward.

[0037] From the above, it can be seen that the utility model can realize the operation of pasting, tearing and pulling the line of the products being conveyed on the existing folder-gluing machine production line, so as to replace the manual operation, improve the production efficiency, save labor costs, and the short pressing stroke makes it possible to adapt to the fast transmission speed of the conveyor belt;

[0038] Among them, since the first pressing wheel 9 follows the shell 6 to rotate downward and upward with the rotating shaft 7 as the axis, the first pressing wheel 9 will have a forward buckling effect when moving downward to press the tear line, thereby ensuring that the first pressing wheel 9 can drive the end of the tear line when pressing down, so as to avoid the inability to press the end of the tear line when moving straight up and down.

[0039] The present invention uses a photoelectric sensor to measure the length of the tape. This sensor is placed along the product's conveyor path. When the product passes through the sensor, it blocks light. The sensor then calculates the product's length based on the duration of the light blockage and the product's conveyor speed. This highly accurate measurement method is suitable for tape operations with stringent product length requirements.

[0040] Preferably, a second pressing wheel 12 is provided on the fixed plate 1 , and the second pressing wheel 12 is located on a side of the cutter 1001 away from the first pressing wheel 9 .

[0041] Specifically, after the product passes through the first pressing wheel 9 and is pressed against the tear line, and is cut by the cutter 1001, it will pass through the second pressing wheel 12 along the conveyor belt. The second pressing wheel 12 can be used to roll the tear line attached to the product for a second time, so that the tear line is completely and tightly attached to the product. For example, after the tear line is cut by the cutter 1001, the first pressing wheel 9 cannot roll the end of the thread. At this time, the secondary rolling of the second pressing wheel 12 at the rear can compact the end of the thread.

[0042] Preferably, the height of the cutter 1001 is lower than the highest rising height of the first crimping wheel 9 .

[0043] Specifically, when the first crimping wheel 9 rises, the height of the cutter 1001 is set to be lower than the highest point of the first crimping wheel 9 to ensure that the cutter 1001 can collide with and cut the stretched tear line.

[0044] Preferably, the guide wheel 8 has two convex rings 801 , and a limited space 802 is formed between the two convex rings 801 .

[0045] Specifically, when the tear line passes through the wire wheel 8, the limiting space 802 formed between the two convex rings 801 can be used to limit the tear line, thereby preventing the position of the tear line from being offset during the pressing process, resulting in the wrong position of the pasted tear line.

[0046] Preferably, a built-in plate 13 is provided in the housing 6 , and the side of the built-in plate 13 facing the cutter 1001 has a jaw 1301 , the first crimping wheel 9 is rotatably connected in the jaw 1301 , and a spring 14 is connected between the built-in plate 13 and the housing 6 .

[0047] When the first pressing wheel 9 continuously presses and tears the product, the first pressing wheel 9 will collide with the conveyor belt continuously at a very high speed. At this time, the first pressing wheel 9 is installed using the built-in plate 13, and the vibration force generated during the collision is absorbed by the spring 14 between the built-in plate 13 and the shell 6 to avoid continuous high-speed collisions that cause the structure of the first pressing wheel 9 to become easily loose, thereby improving the service life of the first pressing wheel 9.

[0048] Preferably, a connecting shaft 15 is provided at the upper end of the housing 6 , and the pushing mechanism 11 is connected to the connecting shaft 15 .

[0049] Specifically, the pushing mechanism 11 is connected to the connecting shaft 15 to push the housing 6 to rotate.

[0050] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
