[0003] In modern industrial production, the bonding of packaging materials is a crucial step in ensuring product integrity and functionality. Adhesive coating equipment, as a key device in this process, is widely used in food packaging, electronic product encapsulation, and building materials. With the increasing market demand for diversified packaging materials, especially the growing use of irregularly shaped or complex-structured materials, higher requirements are being placed on adhesive coating technology. Traditional coating methods often fail to meet the special bonding needs of irregularly shaped parts, leading to low production efficiency or substandard bonding quality. Therefore, developing a continuous adhesive coating device capable of adapting to complex-shaped materials and achieving precise coating is of great significance.
[0004] While existing technologies can meet the coating needs of conventional materials to some extent, their limitations are particularly pronounced when dealing with irregularly shaped parts. For example, when it is necessary to apply adhesive along the edges of a material or to apply it along a specific path on the material surface, existing devices often can only coat the entire surface of the material, failing to achieve precise control. This not only increases adhesive consumption but may also lead to adhesive overflow or uneven coating, affecting the bonding quality. Utility Model Content
[0005] The purpose of this application is to address the problem that existing devices often only apply adhesive to the entire surface of a material when it is necessary to apply adhesive along the edge of the material or along a specific path on the material surface. This results in a lack of precise control, which not only increases adhesive consumption but may also lead to adhesive overflow or uneven application, affecting the bonding quality. This application provides a continuous adhesive application device for packaging materials.
[0006] To achieve the above objectives, this application specifically adopts the following technical solution:
[0007] A continuous adhesive coating device for packaging materials includes an arched outer shell. A transverse sliding groove is formed at the top inner surface of the arched outer shell. A transverse sliding block is slidably connected inside the transverse sliding groove. A lifting sliding groove is formed at one end of the transverse sliding block. A lifting carriage is slidably connected inside the lifting sliding groove. A scraper is fixedly connected to one bottom end of the lifting carriage. A glue storage box is fixedly connected to the top of the lifting carriage. A glue dispensing pump is fixedly connected to the output end of the glue storage box. A glue dispensing head is fixedly connected to the output end of the glue dispensing pump. Symmetrical slots are formed inside the arched outer shell, and templates are inserted into the slots. A conveyor belt is provided at the bottom inner surface of the lifting carriage. A drive mechanism is installed inside the arched outer shell.
[0008] By adopting the above technical solution, and by setting up a drive mechanism in conjunction with a scraper, glue storage box, glue pump, glue dispensing head, and template, it is convenient to select a template with corresponding irregular grooves according to the irregular surface of the workpiece, insert it into the slot, then start the glue pump to squeeze glue through the glue dispensing head to the top of the template, and start the drive assembly to push the scraper to coat the glue with the top of the template, so that the glue is evenly coated on the irregular surface of the workpiece through the irregular groove, effectively improving the bonding quality of the glue.
[0009] Furthermore, the driving mechanism includes a screw rotatably connected inside the transverse sliding groove, a motor is fixedly connected to one end of the arched housing, the output end of the motor is fixedly connected to the screw, and an adjustment component is installed at one end of the arched housing.
[0010] By adopting the above technical solution, and by setting the adjustment component in conjunction with the screw and motor, the starting motor can drive the screw to connect with the transverse slider threadedly, and drive the transverse slider to move the scraper along the guide direction of the screw. When the scraper passes through the top of the irregular groove, it fits against the top of the template along the length direction of the lifting groove, thereby allowing the scraper to push the glue to be applied along the length direction of the screw, which effectively improves the practicality of the device.
[0011] Furthermore, the adjustment assembly includes a guide slide rod fixedly connected inside the arched housing, one end of the guide slide rod being fixedly connected to a lifting slide rod, and one end of the lifting slide being fixedly connected to an adjustment rod that abuts against the guide slide rod.
[0012] By adopting the above technical solution, and by setting the adjustment rod in conjunction with the guide slide and the lifting slide, it is easy for the lifting slide to move under the action of gravity so that the top of the adjustment rod, the guide slide, and the lifting slide come into contact with each other. As the adjustment rod moves the lifting slide between the guide slide and the lifting slide, it pushes the lifting slide along the length of the lifting slide groove, thereby facilitating the adjustment of the scraping height of the scraper and improving the practicality of the device.
[0013] Furthermore, a return spring is fixedly connected to the top of the lifting slide, and the return spring is installed inside the lifting slide groove.
[0014] By adopting the above technical solution and using the return spring in conjunction with the lifting slide, the elastic characteristics of the return spring are utilized to ensure that the return spring rebounds and pushes the lifting slide to keep the adjusting rod in contact with one end of the guide slide and the lifting slide, thus effectively improving the practicality of the device.
[0015] Furthermore, a roller sleeve is rotatably fitted onto one end of the adjusting rod.
[0016] By adopting the above technical solution and setting up the cooperation between the roller sleeve and the adjusting rod, the adjusting rod forms a rolling contact with the guide slide and the lifting slide through the roller sleeve, which effectively reduces the wear of the adjusting rod, improves the stability of the device, and extends the service life of the device.
[0017] Furthermore, rubber pads are symmetrically fixedly connected inside the card slot.
[0018] By adopting the above technical solution and using the rubber pad in conjunction with the template, the template forms a flexible contact between the rubber pad and the slot, thereby improving the installation stability of the template.
[0019] Furthermore, the interior of the arched shell is symmetrically fixed with insert blocks, one end of which is slidably inserted with a cross pin, the top of the slot has an insertion hole one, one end of the template has a symmetrical insertion hole two, the bottom of the cross pin passes through the insertion hole one and the insertion hole two, one end of the cross pin is fitted with a locking spring, and the locking spring is installed between the cross pin and the insert block.
[0020] By adopting the above technical solution, and by setting the locking spring in conjunction with the second insertion hole, the first insertion hole, and the cross pin, the elastic characteristics of the locking spring are utilized so that when the template is inserted into the slot and the second insertion hole is aligned with the first insertion hole, the locking spring rebounds and pushes out the cross pin, pushing one end of the cross pin into the slots. This creates a snap-fit connection between the template and the slot, thereby effectively improving the installation stability of the template.
[0021] Furthermore, multiple support rollers are uniformly rotatably connected inside the arched outer shell, and the support rollers roll against the bearing end of the template.
[0022] By adopting the above technical solution and using the support rollers in conjunction with the template, the support strength and stability of the template are effectively improved.
[0023] In summary, this application includes at least one of the following beneficial effects:
[0024] 1. By setting up a drive mechanism in conjunction with a scraper, glue storage box, glue pump, glue dispensing head, and template, it is easy to select a template with corresponding irregular grooves according to the irregular surface of the workpiece, insert it into the slot, then start the glue pump to squeeze glue through the glue dispensing head to the top of the template, and start the drive assembly to push the scraper to carry the glue to the top of the template for coating, so that the glue is evenly coated on the irregular surface of the workpiece through the irregular groove, effectively improving the bonding quality of the glue.
[0025] 2. By setting a locking spring in conjunction with the second and first insertion holes and the cross pin, the elastic characteristics of the locking spring are utilized so that when the template is inserted into the slot and the second insertion hole is aligned with the first insertion hole, the locking spring rebounds and pushes out the cross pin, pushing one end of the cross pin into the slots. This creates a snap-fit connection between the template and the slot, effectively improving the installation stability of the template. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0033] This application discloses an adhesive continuous coating apparatus for packaging materials.
[0034] Reference Figure 1 - Figure 3A continuous adhesive coating device for packaging materials includes an arched outer shell 1, a transverse sliding groove 2 opened at the inner top of the arched outer shell 1, a transverse sliding block 3 slidably connected inside the transverse sliding groove 2, a lifting sliding groove 4 opened at one end of the transverse sliding block 3, a lifting slide 5 slidably connected inside the lifting sliding groove 4, a scraper 6 fixedly connected to one bottom end of the lifting slide 5, an adhesive storage box 7 fixedly connected to the top of the lifting slide 5, an adhesive dispensing pump 8 fixedly connected to the output end of the adhesive storage box 7, an adhesive dispensing head 9 fixedly connected to the output end of the adhesive dispensing pump 8, symmetrical slots 10 opened inside the arched outer shell 1, a template 11 inserted inside the slots 10, a conveyor belt 12 provided at the inner bottom of the lifting slide 5, and a drive mechanism installed inside the arched outer shell 1.
[0035] The drive mechanism includes a screw 13 rotatably connected inside the transverse slide 2, a motor 14 fixedly connected to one end of the arched housing 1, the output end of the motor 14 fixedly connected to the screw 13, and an adjustment component installed at one end of the arched housing 1.
[0036] Furthermore, the adjustment assembly includes a guide slide rod 15 fixedly connected inside the arched housing 1, a lifting slide rod 16 fixedly connected to one end of the guide slide rod 15, and an adjustment rod 17 that abuts against the guide slide rod 15 fixedly connected to one end of the lifting slide 5.
[0037] Furthermore, a return spring 18 is fixedly connected to the top of the lifting slide 5, and the return spring 18 is installed inside the lifting slide 4;
[0038] Furthermore, a roller sleeve 19 is rotatably fitted onto one end of the adjusting rod 17.
[0039] In use, firstly, according to actual needs, select a template 11 with a suitable irregular through groove and insert it into the slot 10. Then, start the conveyor belt 12 to transport the workpiece to the bottom of the template 11. At the same time, start the glue pump 8 to squeeze the glue stored in the glue storage box 7 through the glue dispensing head 9 onto the top of the template 11. Then, start the motor 14 to drive the screw 13 to form a threaded connection with the transverse slider 3, thereby driving the transverse slider 3 to move the lifting slide 5 along the length direction of the guide slide 15. At the same time, the lifting slide 5 drives the scraper 6 to push the glue along the length direction of the guide slide 15 to coat the top of the template 11. When the scraper 6 pushes the glue across the top of the irregular through groove, the glue passes through the irregular through groove and is coated on the irregular surface of the top of the workpiece. At the same time, the lifting slide 5 drives the adjusting rod 17 to drive the roller sleeve 19 to form rolling contact with the guide slide 15. Then, when the lifting slide 5 drives the adjusting rod 17 to move to one end of the lifting slide 16, the lifting slide 16 pushes the adjusting rod 17 to lift the slide. The slide 5 moves upward along the length of the lifting slide 4, causing the lifting slide 5 to compress the return spring 18 and deform. This causes the lifting slide 5 to pull the scraper 6 away from the template 11, thus removing the scraper 6 from pushing and coating the adhesive. Then, when the reverse start motor 14 drives the screw 13 and the transverse slider 3 to move in the opposite direction along the length of the guide slide 15, the elastic properties of the return spring 18 cause the return spring 18 to push the lifting slide 5 to drive the adjusting rod 17 to always be in contact with the bottom of the lifting slide 16 and the guide slide 15. This allows the lifting slide 5 to drive the scraper 6 to adhere to the top of the template 11 and push the adhesive along the length of the guide slide 15 for coating. This facilitates the setting of corresponding templates 11 according to the irregular surface of the workpiece, and the application of adhesive to the irregular surface of the workpiece through the irregular groove opened on the surface of the template 11 by the scraper 6. This effectively improves the uniformity of adhesive coating and the bonding quality of the adhesive.
[0040] Reference Figure 1 and Figure 2 Rubber pads 20 are symmetrically fixed inside the card slot 10.
[0041] When in use, when the traction template 11 is inserted into the slot 10, the template 11 compresses the rubber pad 20 to produce a contraction deformation. Utilizing the elastic properties of the rubber pad 20, the rubber pad 20 rebounds and forms contact with one end of the template 11, thereby effectively improving the installation stability of the template 11 inside the slot 10, reducing the possibility of the template 11 becoming loose inside the slot 10, and improving the practicality of the device.
[0042] Reference Figure 1 and Figure 2 , Figure 4Inside the arched outer shell 1, there are symmetrically fixedly connected insert blocks 21. One end of the insert block 21 is slidably inserted with a cross pin 22. The top of the slot 10 is provided with an insertion hole 23. One end of the template 11 is symmetrically provided with an insertion hole 24. The bottom of the cross pin 22 passes through the insertion hole 23 and the insertion hole 24. One end of the cross pin 22 is fitted with a locking spring 25. The locking spring 25 is installed between the cross pin 22 and the insert block 21.
[0043] In use, firstly, manually pull one end of the cross pin 22 through the insert block 21 and compress the locking spring 25 to produce a contraction deformation. Then, after pulling the template 11 into the slot 10, the template 11 drives the second insertion hole 24 to align with the first insertion hole 23. Utilizing the elasticity of the locking spring 25, the locking spring 25 rebounds and pushes out the cross pin 22. At the same time, one end of the cross pin 22 passes through the first insertion hole 23 and the second insertion hole 24, thereby forming a snap-fit fixation between the template 11 and the slot 10, further improving the installation stability of the template 11.
[0044] Reference Figure 1 and Figure 2 , Figure 4 Multiple support rollers 26 are uniformly rotated inside the arched outer shell 1, and the support rollers 26 roll against the bearing end of the template 11.
[0045] When the workpiece surface conveyed by the conveyor belt 12 is coated with adhesive by the drive scraper 6 through the template 11, the support roller 26 forms a rolling contact with the bottom of the bearing end of the conveyor belt 12, thereby improving the support strength of the conveyor belt 12 for the workpiece and improving the stability of the workpiece, thus effectively improving the coating stability of the adhesive.
[0046] The implementation principle of the adhesive continuous coating device for packaging materials in this embodiment is as follows: First, manually pull one end of the cross pin 22 through the insert block 21 and squeeze the locking spring 25 to generate a contraction deformation. Then, according to actual needs, select a template 11 with a suitable irregular through groove and insert it into the slot 10. Make the template 11 drive the second insertion hole 24 to align with the first insertion hole 23. Then, using the elastic characteristics of the locking spring 25, make the locking spring 25 rebound and push out the cross pin 22. At the same time, make one end of the cross pin 22 pass through the first insertion hole 23 and the second insertion hole 24, thereby forming a snap-fit fixation between the template 11 and the slot 10.
[0047] Then, the conveyor belt 12 is started to transport the workpiece to the bottom of the template 11. At the same time, the glue pump 8 is started to squeeze the glue stored in the glue storage box 7 through the glue dispensing head 9 onto the top of the template 11. Then, the motor 14 is started to drive the screw 13 to form a threaded connection with the transverse slider 3, thereby driving the transverse slider 3 to move the lifting slide 5 along the length direction of the guide slide 15. At the same time, the lifting slide 5 drives the scraper 6 to push the glue along the length direction of the guide slide 15 to coat the top of the template 11. When the scraper 6 pushes the glue across the top of the irregular through groove, the glue passes through the irregular through groove and is coated on the irregular surface of the top of the workpiece. At the same time, the lifting slide 5 drives the adjusting rod 17 to drive the roller sleeve 19 to form a rolling contact with the guide slide 15. Then, the lifting slide 5 drives the adjusting rod 17 to move to the lifting slide 16. When the lifting slide 16 pushes the adjusting rod 17 to move the lifting slide 5 upward along the length of the lifting slide 4, the lifting slide 5 compresses the return spring 18 to generate contraction deformation, and the lifting slide 5 drives the scraper 6 to disengage from the template 11, thereby causing the scraper 6 to disengage from pushing and applying the adhesive. Then, when the reverse start motor 14 drives the screw 13 to be threadedly connected to the transverse slider 3, and the lifting slide 5 drives the scraper 6 to move in the reverse direction along the length of the guide slide 15, the elastic characteristics of the return spring 18 are used to make the return spring 18 push the lifting slide 5 to always contact the bottom of the lifting slide 16 and the guide slide 15, so that the lifting slide 5 drives the scraper 6 to adhere to the top of the template 11 and push the adhesive along the length of the guide slide 15 for application.
