Description

Technical Field

[0001] This utility model relates to the field of trademark coating technology, specifically to a two-color trademark coating mechanism. Background Technology

[0002] In the field of trademark production and processing, adhesive application is a key process to ensure that the trademark and the carrier are firmly bonded. Especially for two-color trademarks, precise adhesive application is required to achieve independent delivery of the two adhesives and a clear coating effect. The quality of adhesive application directly affects the appearance integrity and reliability of the trademark. With the increasing demand for personalized and diversified trademarks in the consumer market, the application scope of two-color trademarks is constantly expanding, which puts forward higher requirements for the automation level, adhesive volume control accuracy and operational stability of the adhesive application mechanism.

[0003] Existing two-color label coating facilities have the following shortcomings: Traditional two-color label coating equipment has significant shortcomings in the glue quantity monitoring and replenishment process. Early coating equipment relied heavily on manual management of the glue supply. Operators had to periodically observe the glue level through the transparent glue storage container or open the glue storage cover to sample and test. When the glue quantity was insufficient, they had to manually open the glue supply valve to replenish the glue, which consumed a lot of manpower.

[0004] At the same time, manual glue application is highly subjective and prone to problems such as applying too much or too little glue, resulting in glue waste or unstable subsequent glue application, which further reduces the product qualification rate. Utility Model Content

[0005] The purpose of this utility model is to provide a two-color trademark coating mechanism.

[0006] To achieve this objective, the present invention adopts the following technical solution: A two-color trademark coating mechanism is provided, including a coating body, a top box, a dispensing mechanism, and a dispensing head. The top box is fixed on the top of the coating body, and the dispensing mechanism is fixed inside the top box. The dispensing mechanism includes a glue storage bottle, a glue delivery tube, a sealing seat, a sealing plug, a glue supply tube, and a glue outlet tube. There are multiple sets of glue storage bottles, which are equidistantly arranged and fixed on the surface of the top box, and the number of glue storage bottles and the number of dispensing heads are the same. The glue delivery tube is fixed between the glue storage bottle and the dispensing head. The sealing seat is located above the glue storage bottle, and the sealing plug is located on one side of the sealing seat. The glue supply tube is fixed on the top of the sealing seat, and the dispensing tube is fixed on the bottom of the sealing seat.

[0007] Preferably, the sealing seat has a sealing groove inside that is compatible with the sealing plug, and the glue supply pipe and the glue outlet pipe are connected through the sealing groove inside the sealing seat, and the ends of multiple sets of glue supply pipes are connected to the same glue supply mechanism.

[0008] Preferably, the glue dispensing mechanism further includes a float, a rack, a positioning frame, a gear, and a glue receiving hopper. The float is slidably connected inside the glue storage bottle, the rack is fixed to the top of the float, the glue receiving hopper is fixed to the top of the glue storage bottle, the positioning frame is fixed inside the glue receiving hopper, and the rack is slidably connected inside the glue receiving hopper, with the gear meshing on the surface of the rack.

[0009] Preferably, the sealing seat is fixed on the surface of the glue receiving hopper, and the end of the glue outlet tube is directly connected to the inside of the glue receiving hopper. A drive shaft is fixed inside the gear, and the drive shaft is rotatably connected to the surface of the sealing seat. A bevel gear pair is fixed at one end of the drive shaft, and a rotating shaft is coaxially fixed inside the bevel gear of the bevel gear pair, and the rotating shaft is rotatably connected to the surface of the sealing seat.

[0010] Preferably, a cam is fixed to the surface of the rotating shaft, the surface of the cam is in contact with the surface of the sealing plug, a relief groove is provided inside the sealing plug, a fixing rod is fixed to one side of the sealing seat, and the sealing plug is slidably connected to the surface of the fixing rod through the relief groove. A spring is wound around the surface of the fixing rod, and the two ends of the spring are respectively fixed between the baffle at the end of the fixing rod and the sealing plug.

[0011] Preferably, the top box is equipped with an adjustment mechanism, which includes an adjustment seat, a limit block, a connecting rod, and a fixed seat. The adjustment seat is fixed inside the top box, the limit block is located inside the adjustment seat, the connecting rod is connected to the surface of the limit block, and the connecting rod consists of two sets of intersecting hinge rods. The fixed seat is connected to the surface of the connecting rod and is fixedly connected to the dispensing head.

[0012] Preferably, the number of limiting blocks is the same as that of the dispensing head, and the limiting block on one side edge is fixedly connected to the adjusting seat, while the bottom of the limiting block on the other side edge is fixed with a threaded block.

[0013] Preferably, the threaded block has an internal threaded connection to a threaded rod, which is rotatably connected to the bottom of the adjusting seat. One end of the adjusting seat is fixed with a motor, and the output end of the motor is fixedly connected to one end of the threaded rod.

[0014] The beneficial effects of this utility model are: 1. This utility model discloses a dual-color trademark glue application mechanism that can accurately sense the liquid level in real time and realize dynamic monitoring of the glue storage volume. The float in the glue storage bottle is in direct contact with the glue level and can rise and fall synchronously with the decrease or replenishment of glue. It can instantly capture subtle changes in the liquid level without the need for electronic signal conversion or manual detection. Compared with traditional timed inspection or electronic sensor sensing, the mechanical sensing method of the float responds more quickly and can provide real-time feedback on the glue storage status, providing a precise trigger signal for subsequent glue replenishment. The entire glue replenishment process does not require manual intervention. Operators do not need to frequently check the glue level or manually open or close the glue supply valve. When the glue in the storage bottle is insufficient, glue replenishment is automatically started. After the glue is replenished to the set level, glue replenishment is automatically stopped, completely freeing up manual labor, reducing labor input, and avoiding problems such as forgetting to replenish glue or over-replenishing glue that may occur with manual operation.

[0015] 2. The present invention relates to a two-color trademark glue application mechanism. Liquid level changes can be directly converted into the opening and closing action of the glue replenishment channel through mechanical components. When the glue is insufficient, the float moves down and can quickly push the sealing plug away from the sealing groove to open the glue replenishment channel. When the glue is sufficient, the reverse transmission can quickly seal the channel. The whole process has no signal delay and effectively avoids glue application interruption caused by untimely glue replenishment.

[0016] 3. The two-color trademark gluing mechanism of this utility model has uniform and precise spacing adjustment, ensuring adaptability to gluing of multiple specifications. It ensures consistent spacing adjustment across multiple dispensing heads, adapting to trademarks with varying widths and two-color spacing requirements. It is especially suitable for high-precision trademarks that demand precise glue application. No manual intervention is required; simply starting the motor allows for mechanical adjustment of all dispensing head spacing. This eliminates the need for operators to manually loosen, move, or fix individual dispensing heads, significantly reducing adjustment time and further ensuring accurate glue application.

[0019] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0021] Reference Figures 1 to 6 The illustrated two-color trademark coating mechanism includes a coating body 1, a top box 2, a glue injection mechanism 3, and a glue dispensing head 6. The top box 2 is fixed to the top of the coating body 1, and the glue injection mechanism 3 is fixed inside the top box 2. The glue injection mechanism 3 includes a glue storage bottle 4, a glue delivery pipe 5, a sealing seat 15, a sealing plug 16, a glue supply pipe 19, and a glue outlet pipe 20. There are multiple sets of glue storage bottles 4, which are equidistantly arranged and fixed on the surface of the top box 2, and the number of glue storage bottles 4 and glue dispensing heads 6 are the same. The glue delivery pipe 5 is fixed between the glue storage bottles 4 and the glue dispensing heads 6. The sealing seat 15 is located above the glue storage bottles 4, the sealing plug 16 is located on one side of the sealing seat 15, the glue supply pipe 19 is fixed to the top of the sealing seat 15, and the glue outlet pipe 20 is fixed to the bottom of the sealing seat 15.

[0022] The sealing seat 15 has a sealing groove inside that matches the sealing plug 16. The glue supply pipe 19 and the glue outlet pipe 20 are connected through the sealing groove in the sealing seat 15. The ends of multiple sets of glue supply pipes 19 are connected to the same glue supply mechanism. The two-color trademark glue coating mechanism is based on the glue coating machine body 1. The top box 2 is fixed on its top and serves as the installation support frame for the glue injection mechanism 3 and the distance adjustment mechanism 22. The glue dripping head 6 is the glue output terminal and corresponds one-to-one with the glue storage bottle 4 in the glue injection mechanism 3 to ensure independent control of the two-color glue coating. The distance adjustment mechanism 22 adjusts the spacing of multiple sets of glue dripping heads 6 through mechanical transmission to adapt to the glue coating needs of different sized trademarks and realize the automated and precise glue coating operation of the two-color trademarks. Multiple sets of glue storage bottles 4 are fixed at equal intervals on the surface of the top box 2 and are connected to the glue dripping head 6 below through the glue supply pipe 5 to form the initial glue delivery path. The glue flows to the glue dripping head 6 through the glue supply pipe 5 under pressure and is finally dripped onto the surface of the trademark.

[0023] The glue dispensing mechanism 3 also includes a float 7, a rack 8, a positioning frame 9, a gear 10, and a glue receiving hopper 21. The float 7 is slidably connected inside the glue storage bottle 4. The rack 8 is fixed to the top of the float 7. The glue receiving hopper 21 is fixed to the top of the glue storage bottle 4. The positioning frame 9 is fixed inside the glue receiving hopper 21, and the rack 8 is slidably connected inside the glue receiving hopper 21. The gear 10 is meshed with the surface of the rack 8. The float 7 is slidably connected inside the glue storage bottle 4. The float 7 rises and falls synchronously with the change in the glue liquid level inside the glue storage bottle 4. When the glue liquid decreases, the liquid level drops, and the float 7 moves down accordingly. When the adhesive is replenished, the liquid level rises, and the float 7 moves upward synchronously. The top of the float 7 is fixed with a rack 8, which slides through the inside of the adhesive receiving hopper 21. The receiving hopper 21 is also fixed with a positioning frame 9, which limits the sliding direction of the rack 8 to ensure that the rack 8 moves only vertically with the float 7. The surface of the rack 8 is meshed with a gear 10, and a drive shaft 11 is fixed inside the gear 10. The drive shaft 11 is rotatably connected to the surface of the sealing seat 15. When the rack 8 rises and falls with the float 7, the change in the adhesive level is converted into the linear motion of the rack 8, which in turn drives the gear 10 to rotate.

[0024] The sealing seat 15 is fixed to the surface of the glue receiving hopper 21, and the end of the glue dispensing tube 20 is directly connected to the inside of the glue receiving hopper 21. A drive shaft 11 is fixed inside the gear 10, and the drive shaft 11 is rotatably connected to the surface of the sealing seat 15. A bevel gear pair 12 is fixed to one end of the drive shaft 11. A rotating shaft 13 is coaxially fixed inside the bevel gear of the bevel gear pair 12, and the rotating shaft 13 is rotatably connected to the surface of the sealing seat 15. A cam 14 is fixed to the surface of the rotating shaft 13, and the surface of the cam 14 is in contact with the surface of the sealing plug 16. A clearance groove is provided inside the sealing plug 16. A fixing rod 17 is fixed to one side of the sealing seat 15, and the sealing plug 16 is slidably connected to the surface of the fixing rod 17 through the clearance groove. A spring 18 is wound around the surface of the fixing rod 17, and the two ends of the spring 18 are respectively fixed between the baffle at the end of the fixing rod 17 and the sealing plug 16. When the glue in the glue storage bottle 4 is insufficient, the float 7 moves down, causing the rack 8 to move down synchronously, thereby driving the gear 10 and the... The drive shaft 11 rotates, and then drives the rotating shaft 13 to rotate through the bevel gear pair 12, thereby causing the long-diameter end of the cam 14 to move away from the sealing plug 16. Under the elastic force of the spring 18, the sealing plug 16 slides along the fixed rod 17 and disengages from the sealing groove inside the sealing seat 15. At this time, the glue supply pipe 19 and the glue outlet pipe 20 are connected through the sealing groove. The glue from the external glue supply mechanism flows into the glue receiving hopper 21 through the glue supply pipe 19, the sealing groove, and the glue outlet pipe 20, and then is injected into the storage tank from the glue receiving hopper 21. The glue bottle 4 enables automatic glue replenishment. When the glue in the storage bottle 4 is fully replenished, the float 7 moves upward, causing the rack 8 to move upward synchronously. This causes the gear 10 and the drive shaft 11 to rotate in opposite directions. Then, the bevel gear pair 12 drives the rotating shaft 13 to rotate in opposite directions, thereby causing the long diameter end of the cam 14 to squeeze the sealing plug 16. This overcomes the elastic force of the spring 18 and pushes the sealing plug 16 into the sealing groove, blocking the channel between the glue supply pipe 19 and the glue outlet pipe 20. Glue replenishment stops, thus achieving automatic and constant control of the glue storage amount.

[0025] An adjusting mechanism 22 is installed inside the top box 2. The adjusting mechanism 22 includes an adjusting seat 23, a limiting block 26, a connecting rod 28, and a fixed seat 29. The adjusting seat 23 is fixed inside the top box 2. The limiting block 26 is located inside the adjusting seat 23. The connecting rod 28 is connected to the surface of the limiting block 26 and consists of two sets of intersecting hinge rods. The fixed seat 29 is connected to the surface of the connecting rod 28 and is fixedly connected to the dispensing head 6. The adjusting seat 23 of the adjusting mechanism 22 is fixed inside the top box 2. Multiple sets of limiting blocks 26 are provided inside the adjusting seat 23. The number of limiting blocks 26 is the same as the number of dispensing heads 6, and one side... The limiting block 26 on the edge is fixed to the adjusting seat 23 as a fixed reference. The bottom of the limiting block 26 on the other edge is fixed with a threaded block 27. The threaded block 27 is internally connected to a threaded rod 24. The threaded rod 24 is rotatably connected to the bottom of the adjusting seat 23, and one end is fixedly connected to the output end of the motor 25 at the end of the adjusting seat 23. Adjacent limiting blocks 26 are connected by a connecting rod 28. The connecting rod 28 consists of two sets of hinged rods that cross each other, forming a parallelogram linkage structure. The end of the connecting rod 28 on the surface of the outermost limiting block 26 is connected to a fixed seat 29. The fixed seat 29 is fixedly connected to the dispensing head 6 to realize the transmission of force and displacement.

[0026] The number of limiting blocks 26 is the same as that of the dispensing head 6. The limiting block 26 on one edge is fixedly connected to the adjusting seat 23, and the bottom of the limiting block 26 on the other edge is fixed with a threaded block 27. When the motor 25 is started, the output end of the motor 25 drives the threaded rod 24 to rotate around its own axis. Since the threaded rod 24 and the threaded block 27 are threadedly engaged, and the threaded block 27 is restricted within the adjusting seat 23 along with the corresponding limiting block 26, it can only slide horizontally and cannot rotate. The rotational motion of the threaded rod 24 is converted into the horizontal linear motion of the threaded block 27 along the axial direction of the threaded rod 24. When the limiting block 26 at the edge moves with the threaded block 27, it drives the adjacent... The limit blocks 26 move synchronously, and due to the parallelogram structure of the connecting rod 28, the spacing between all the limit blocks 26 will increase or decrease uniformly. The motor 25 drives the threaded rod 24 to rotate forward, and the threaded block 27 moves towards the fixed limit block 26. The included angle of the connecting rod 28 decreases, and the spacing between each set of limit blocks 26 decreases. Conversely, the spacing increases. The change in the spacing between the limit blocks 26 is transmitted to the fixed seat 29 through the connecting rod 28, which drives the dispensing head 6 fixed to the fixed seat 29 to move synchronously. Finally, the uniform and precise adjustment of the spacing between multiple sets of dispensing heads 6 is achieved to adapt to the application of glue to two-color trademarks with different widths or spacing requirements. There is no need for manual adjustment one by one, which improves the adjustment efficiency and accuracy.

[0027] The threaded block 27 has an internal threaded connection to a threaded rod 24, which is rotatably connected to the bottom of the adjusting seat 23. One end of the adjusting seat 23 is fixed with a motor 25, and the output end of the motor 25 is fixedly connected to one end of the threaded rod 24. According to the size of the trademark to be coated and the two-color spacing requirements, the motor 25 of the spacing adjustment mechanism 22 is started, and the spacing of the dispensing head 6 is adjusted to the set value. The coating mechanism is started, and the glue in the glue storage bottle 4 flows to the corresponding dispensing head 6 through the glue delivery pipe 5. The dispensing head 6 drips the glue onto the moving trademark surface at a set frequency to complete the coating operation.

[0028] As the adhesive application proceeds, the amount of adhesive in the storage bottle 4 decreases, the liquid level drops, the float 7 moves down, and the glue replenishment channel automatically opens. The external glue supply mechanism replenishes adhesive to the storage bottle 4. After the liquid level rises back to the set height, the glue replenishment channel automatically closes, ensuring a continuous supply of adhesive and avoiding coating defects caused by interruption or insufficient adhesive. If a different specification label is to be changed, it is only necessary to restart the spacing adjustment mechanism 22 to adjust the spacing of the dispensing head 6. There is no need to disassemble or reassemble the glue dispensing components, thus achieving rapid changeover.
