Description

Technical Field

[0001] This invention belongs to the field of glue dispensing devices, and specifically relates to a flexible, modular grooved wedge scraper. Background Technology

[0002] Hot melt adhesive spraying is a process that involves applying a hot melt adhesive to a substrate material to perform bonding and lamination operations. It has wide applications in industries such as non-woven fabrics, papermaking, household paper, baby and women's products, automobiles, packaging, and hygiene materials. Hot melt adhesive squeegees based on this process are a well-known technology.

[0003] A glue scraper gun consists of a gun body and a scraper head. A glue adapter is usually installed between the gun body and the scraper head, and a valve is mounted on the adapter to control the glue flow. During operation, hot melt glue is forced into the gun body by pressure, then passes through the adapter into the scraper head, and finally is scraped onto the material through the scraper nozzle.

[0004] The grooved wedge type scraper gun uses a grooved wedge nozzle, and its scraping path is a single plane, suitable for applying adhesive to materials with smooth surfaces. The valve body of the scraper gun can be divided into different types according to its working principle, such as continuous valve body and reverse-pulse intermittent valve body, which can achieve continuous or intermittent adhesive dispensing respectively. However, existing grooved wedge type scraper guns often have valve bodies, scraper heads, and adhesive adapters that are not easy to replace, and cannot achieve modular assembly. This limits the application scenarios of the scraper gun and increases the inventory costs for manufacturers and customers. Summary of the Invention

[0005] To address the aforementioned issues, the present invention aims to provide a flexible, modular scraper gun, in which the valve body, scraper head, and glue adapter can be modularly assembled for easy replacement, and can be flexibly adjusted to expand application scenarios and reduce inventory and usage costs.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] The present invention also provides a flexible, modular scraper, comprising:

[0008] The glue gun body has an adhesive inlet on its outer wall and an adhesive delivery channel inside, with the adhesive inlet connected to the adhesive delivery channel.

[0009] A scraper head, which has a glue dispensing channel and a scraper nozzle for scraping glue onto the surface of a material, wherein the glue dispensing channel is disposed inside the scraper head, the scraper nozzle is located at the bottom of the scraper head, and the scraper nozzle is connected to the outlet of the glue dispensing channel.

[0010] An adhesive adapter has an adhesive transfer path for introducing adhesive into a scraper head, and the adhesive delivery channel is connected to the inlet of the dispensing channel through the adhesive transfer path.

[0011] Valve body, the valve body being used to control the on / off state of the adapter rubber circuit;

[0012] The glue gun body has a first mounting wall on one side, the glue adapter is detachably mounted on the first mounting wall, the glue adapter has a second mounting wall on one side and a third mounting wall on the other side, the glue scraper head is detachably mounted on the second mounting wall, and the valve body is detachably mounted on the third mounting wall.

[0013] Furthermore, the glue dispensing channel includes: a main channel and multiple sub-channels, both the main channel and the sub-channels being arranged vertically. The glue scraper head has a horizontally arranged glue buffer tank. The inlet of the main channel is connected to the transfer glue path. One end of each of the multiple sub-channels is connected to the outlet of the main channel, and the other end is connected to different positions of the glue buffer tank, so that the glue is evenly dispersed in the glue buffer tank. The glue buffer tank is connected to the glue scraper nozzle.

[0014] Furthermore, one side of the scraper nozzle is an arc-shaped wall, and the other side is a sloping wall, forming a "sharp-angled protruding nozzle with a single-sided arc transition" structure. During adhesive application, the material moves from one side of the arc surface to the other side of the sloping surface. As it passes the scraper nozzle, the nozzle applies the adhesive to the material. This structural design, in the direction facing the material, allows the scraper nozzle to better conform to the material through the arc surface design, reducing material movement and improving the adhesive application effect. In the direction away from the material, the sloping surface design reduces adhesive adhesion.

[0015] Furthermore, the bottom wall of the glue gun body has a slope, with the lower end of the slope close to the glue adapter and the upper end away from the glue adapter. The arc-shaped wall is located on the side of the glue nozzle close to the slope, and the sloped wall is located on the side of the glue nozzle away from the slope. The sloped design avoids direct contact between the glue gun body and the material. Combined with the arc-shaped wall design, it increases the adjustable space between the glue nozzle and the material, which is beneficial for the material to better conform to the arc surface of the glue nozzle, reducing material bounce. It also facilitates the adhesion between the material and the glue nozzle, improving the glue application quality.

[0016] Furthermore, the inclination angle of the inclined plane is 15-30 degrees.

[0017] Furthermore, the scraping head includes a panel and a base plate, which are detachably connected by bolts. The scraping nozzle is located between the panel and the base plate, with the arc-shaped wall on the panel and the inclined wall on the base plate.

[0018] Furthermore, the main channel is located inside the base plate, while the sub-channels and glue buffer tank are both located inside the panel.

[0019] Furthermore, the third mounting wall is located on the top surface of the adhesive adapter, and the second mounting wall is located on the bottom surface of the adhesive adapter.

[0020] Furthermore, the valve body includes a continuous valve body and a reverse-pulse intermittent valve body. Through modular installation, it can be flexibly replaced. A solenoid valve is also installed on the valve body to control the operation of the valve body.

[0021] Furthermore, the adhesive adapter has a fourth mounting wall that fits into the first mounting wall. The first mounting wall has one or more first connecting holes, and the fourth mounting wall has one or more second connecting holes. The first connecting holes and the second connecting holes are connected to each other, and a first connector is detachably installed through the first connecting hole and the second connecting hole.

[0022] Furthermore, the first connecting hole and the second connecting hole are threaded holes, and the first connecting member is a screw. The screw of the first connecting member is threaded into the threaded holes of the first connecting hole and the second connecting hole, so as to realize the detachable connection between the glue adapter and the glue gun body, thereby facilitating the disassembly and replacement of the glue adapter and realizing the modular installation of the glue adapter.

[0023] Furthermore, the adhesive delivery channel extends to the first mounting wall to form an adhesive channel outlet, and the inlet of the transfer adhesive path extends to the fourth mounting wall to form an adhesive path inlet, with the adhesive channel outlet and the adhesive path inlet being connected opposite each other.

[0024] Furthermore, one side of the scraper head has a fifth mounting wall, which is attached to the second mounting wall. The second mounting wall has one or more third connecting holes, and the fifth mounting wall has one or more fourth connecting holes. The third connecting holes and the fourth connecting holes are connected to each other, and a second connector is detachably installed through the third connecting holes and the fourth connecting holes.

[0025] Furthermore, the third and fourth connecting holes are threaded holes, and the second connector is a screw. The screw of the second connector is threaded into the threaded holes of the third and fourth connecting holes, thereby realizing a detachable connection between the glue scraper head and the glue adapter, which facilitates the disassembly and replacement of the glue scraper head and realizes the modular installation of the glue scraper head.

[0026] Furthermore, the outlet of the transfer adhesive path extends to the second mounting wall to form an adhesive path outlet, and the inlet of the adhesive outlet channel extends to the fifth mounting wall to form an adhesive spraying inlet, with the adhesive path outlet and the adhesive spraying inlet being connected opposite each other.

[0027] Furthermore, a valve body docking groove is provided on the third mounting wall, the adapter adhesive path passes through the valve body docking groove, and the lower part of the valve body is installed in the valve body docking groove so as to realize the conduction or blocking of the adapter adhesive path by the movement of the valve stem.

[0028] Furthermore, the third mounting wall has one or more fifth connecting holes, and the valve body has one or more sixth connecting holes. The fifth connecting holes and the sixth connecting holes are connected to each other, and a third connecting member is detachably installed through the fifth connecting hole and the sixth connecting hole.

[0029] Furthermore, the fifth and sixth connecting holes are threaded holes, and the third connecting member is a screw. The screw of the third connecting member is threaded into the threaded holes of the fifth and sixth connecting holes, realizing a detachable connection between the valve body and the glue adapter, thereby facilitating the disassembly and replacement of the valve body and realizing modular installation of the valve body.

[0030] Furthermore, the glue gun body is also equipped with a glue filter tank, and a glue filter is installed in the glue filter tank. The glue filter is located on the path of the glue delivery channel. After the glue enters the glue delivery channel from the glue inlet, it is filtered by the glue filter and then enters the glue scraper head from the glue adapter for glue dispensing.

[0031] Furthermore, multiple glue inlets are provided, which are respectively opened on the top wall, side wall, and back wall of the glue gun body, so as to realize glue feeding from multiple directions and improve glue feeding efficiency.

[0032] Furthermore, the glue inlet is equipped with a glue inlet connector, which can be connected to an external glue inlet device to realize glue inlet.

[0033] Furthermore, the glue delivery channel and the transfer glue path are provided in multiple ways. Each glue delivery channel is paired with one of the transfer glue paths, and the multiple glue delivery channels are arranged longitudinally and parallel within the glue gun body. The glue gun body also has heating rods arranged laterally, intersecting with the glue delivery channels, to heat the glue within the delivery channels, preventing solidification and ensuring smooth flow. The multiple glue delivery channels deliver the glue to their corresponding transfer glue paths one-to-one, and then the glue enters the scraper nozzle through its respective dispensing channel for dispensing. The heating rods are arranged laterally, with a consistent distance from all glue delivery channels, evenly dispensing the glue across all channels. This results in a high degree of temperature uniformity for the glue within the multiple delivery channels, leading to a more uniform dispensing speed at each scraper nozzle.

[0034] Furthermore, the glue gun body has a sixth mounting wall on the same side of the first mounting wall, the sixth mounting wall is arranged side by side with the valve body, and there is a gap between the two.

[0035] The beneficial effects of this invention are as follows: Compared with the prior art, the glue adapter of the glue gun body of this application can be detachably installed on the first mounting wall of the glue gun body, and the glue scraper head and valve body can be detachably installed on the second mounting wall and the third mounting wall of the glue adapter, respectively. This enables modular assembly of the valve body, glue scraper head and glue adapter, and allows for flexible replacement of the valve body, glue scraper head and glue adapter, achieving flexible adjustment. This not only improves the application scenarios but also reduces the cost of inventory and use. Attached Figure Description

[0052] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0053] To achieve the above objectives, the technical solution of the present invention is as follows:

[0054] See Figures 1-11 This embodiment provides a flexible, modular grooved wedge scraper, comprising:

[0055] The glue gun body 1 has an inlet 11 on its outer side wall and an adhesive delivery channel 13 for delivering hot melt adhesive inside. The inlet 11 is connected to the adhesive delivery channel 13.

[0056] The glue scraper head 2 is a grooved wedge scraper nozzle, which has a glue outlet channel 21 for conveying glue liquid and a glue scraper nozzle 22 for scraping glue onto the material surface. The glue scraper nozzle 22 is located at the bottom of the glue scraper head 2 and is connected to the outlet of the glue outlet channel.

[0057] The glue adapter 3 has a glue transfer path 31 for introducing glue into the scraper head 2, and the glue delivery channel 13 is connected to the inlet of the glue outlet channel 21 through the glue transfer path 31.

[0058] Valve body 4, the valve body 4 being used to control the on / off state of the adapter rubber circuit 31;

[0059] The glue gun body 1 has a first mounting wall 15 on one side, the glue adapter 3 is detachably mounted on the first mounting wall 15, the glue adapter 3 has a second mounting wall 33 on one side and a third mounting wall 34 on the other side, the glue scraper head 2 is detachably mounted on the second mounting wall 33, and the valve body 4 is detachably mounted on the third mounting wall 34.

[0060] The working principle of the glue spray gun in this application is as follows: external hot melt adhesive enters the glue gun body 1 from the glue inlet 11, then enters the glue transfer path 31 of the glue transfer seat 3 from the glue delivery channel 13, then enters the glue outlet channel 21 of the glue scraper head 2 from the glue transfer path 31, and finally scrapes the glue onto the material that needs to be coated from the glue scraper nozzle 22; a pneumatic solenoid valve 5 is installed on the valve body 4, and the pneumatic solenoid valve 5 controls the external air source to enter the valve body 4 from different inlets, pushing the valve rod up and down to realize the opening or blocking of the glue transfer path 31. When the glue transfer path 31 is open, the glue can smoothly enter the glue scraper head 2 for scraping. When the glue transfer path 31 is blocked, the glue cannot enter the glue scraper head 2, thereby realizing the control of the glue spraying of the glue spray gun.

[0061] In this embodiment, since the glue gun body 1, glue adapter 3, and glue scraper head 2 are modularly assembled, they have the advantage of flexible assembly. Based on different application requirements, they can be configured as follows:

[0062] 1. Set up one glue scraper gun body 1, corresponding to multiple different adapter seats, valve body combinations and glue scraper heads, such as: see Figure 1A 200mm wide scraper gun can be fitted with adapters for four valve bodies and one scraper head. The scraper head contains four glue inlet structures, each corresponding one-to-one with a valve body, allowing each valve body to control the glue dispensing to each inlet structure individually. (See also...) Figure 9 The 225mm wide scraper can also be equipped with an adapter seat for eight valve bodies and a scraper head. The scraper head has eight glue inlet structures, each of which corresponds one-to-one with each valve body, so that each valve body can achieve one-to-one glue dispensing control for each glue inlet structure.

[0063] 2. See Figure 10-11 The 990mm wide scraper gun has three scraper gun bodies 1 with the same width. Each scraper gun body 1 is 330mm wide. The three scraper gun bodies 1 are installed on a glue adapter 3. Each scraper gun body 1 can apply different glues, and can realize the application of glues of different materials and colors, adapting to different scraping needs.

[0064] In this embodiment, the valve body 4 is either a continuous valve body or a reverse-pulse intermittent valve body. The stroke and flow rate of the continuous valve body can be adjusted, while the stroke and flow rate of the reverse-pulse intermittent valve body cannot be adjusted. Both are existing technologies and can be selected according to different application scenarios. Since the continuous valve body and the reverse-pulse intermittent valve body are both conventional modules in the field and belong to the prior art, they will not be described in detail here.

[0065] Compared to existing technologies, the advantages of this embodiment are as follows: the glue adapter 3 is detachably mounted on the first mounting wall 15 of the glue gun body 1, and the glue scraper head 2 and valve body 4 are detachably mounted on the second mounting wall 33 and the third mounting wall 34 of the glue adapter 3, respectively. This enables modular assembly of the valve body 4, glue scraper head 2, and glue adapter 3. Users can purchase only one glue adapter 3 and replace it with different valve bodies 4, reducing inventory costs. One glue adapter 3 can be equipped with one or more valve bodies 4, which can be flexibly selected to achieve intermittent, continuous, and intermittent-continuous combinations, solving the composite needs of different materials and achieving flexible adjustment, thus improving application scenarios. At the same time, for applications with various types and amounts of glue on a single material, one glue adapter 3 can be used with multiple glue gun bodies 1. Each glue gun body 1 can apply different glues to different materials, thereby solving the composite needs of different materials.

[0066] In this embodiment, the scraper head 2 adopts a grooved wedge-shaped scraper nozzle. One side of the scraper opening 22 is an arc-shaped wall 221, and the other side is an inclined wall 222, forming a structure with a "single-sided arc-shaped transition pointed convex nozzle". During glue application, the material moves from one side of the arc-shaped wall 221 to the other side of the inclined wall 222. When passing through the scraper opening 22, the scraper opening 22 applies glue to the material. The design of the above structure allows the scraper opening to better fit the material in the direction facing the material, reducing material bounce and improving the glue application effect. In the direction away from the material, the inclined design reduces glue adhesion.

[0067] Furthermore, the bottom wall of the glue gun body 1 has a slope 14. The lower end of the slope 14 is close to the glue adapter 3, and the upper end of the slope 14 is away from the glue adapter 3. The arc-shaped wall 221 is located on the side of the glue nozzle 22 close to the slope 14, and the slope 222 is located on the side of the glue nozzle 22 away from the slope 14. The design of the slope 14 can avoid direct contact between the glue gun body 1 and the material. Combined with the design of the arc-shaped wall 221, it can increase the adjustable space between the glue nozzle and the material, which is conducive to the material better adhering to the arc surface of the glue nozzle, reducing material bounce, and also facilitates the adhesion between the material and the glue nozzle, improving the glue application quality.

[0068] Furthermore, the inclination angle of the inclined plane 14 is 20 degrees.

[0069] Furthermore, the scraping head 2 includes a panel 23 and a base plate 24, which are detachably connected by bolts. The scraping nozzle 22 is located between the panel 23 and the base plate 24, and the arc-shaped wall 221 is located on the panel 23 and the inclined wall 222 is located on the base plate 24.

[0070] Furthermore, the glue dispensing channel 21 includes: a main channel 211 and multiple branch channels 212. The main channel 211 and the branch channels 212 are both arranged vertically. The glue scraper head 2 has a horizontally arranged glue buffer tank 28. The inlet of the main channel 211 is connected to the transfer glue path. One end of each of the multiple branch channels 212 is connected to the outlet of the main channel 211, and the other end is connected to different positions of the glue buffer tank 28, so that the glue is evenly dispersed in the glue buffer tank 28. The glue buffer tank 28 is connected to the glue scraper nozzle.

[0071] Furthermore, the main channel 211 is located within the base plate 24, and the sub-channels 212 and the glue buffer tank 28 are both located within the panel 23.

[0072] Furthermore, the third mounting wall 34 is located on the top surface of the adhesive adapter 3, and the second mounting wall 33 is located on the bottom surface of the adhesive adapter 3.

[0073] Furthermore, the adhesive adapter 3 has a fourth mounting wall 35, which is attached to the first mounting wall 15. The first mounting wall 15 has one or more first connecting holes 16, and the fourth mounting wall 35 has one or more second connecting holes 36. The first connecting hole 16 and the second connecting hole 36 are connected to each other. A first connector 6 is detachably installed through the first connecting hole 16 and the second connecting hole 36.

[0074] Furthermore, the first connecting hole 16 and the second connecting hole 36 are threaded holes, and the first connecting member 6 is a screw. The screw of the first connecting member 6 is threaded into the threaded holes of the first connecting hole 16 and the second connecting hole 36, so as to realize the detachable connection between the glue adapter 3 and the glue gun body 1, thereby facilitating the disassembly and replacement of the glue adapter 3 and realizing the modular installation of the glue adapter 3.

[0075] Furthermore, the adhesive delivery channel 13 extends to the first mounting wall 15 to form an adhesive channel outlet 17, and the inlet of the adapter adhesive path 31 extends to the fourth mounting wall 35 to form an adhesive path inlet 37. The adhesive channel outlet 17 is connected to the adhesive path inlet 37. This structure, while ensuring that the adhesive adapter 3 is modularly assembled on the caulking gun body 1, also enables communication between the adhesive delivery channel 13 and the adapter adhesive path 31, thereby allowing the adhesive from the caulking gun body 1 to be introduced into the adhesive adapter 3.

[0076] Furthermore, one side of the scraper head 2 has a fifth mounting wall 25, which is attached to the second mounting wall 33. The second mounting wall 33 has one or more third connecting holes 39, and the fifth mounting wall 25 has one or more fourth connecting holes 26. The third connecting holes 39 and the fourth connecting holes 26 are connected to each other. A second connector 7 is detachably installed through the third connecting holes 39 and the fourth connecting holes 26.

[0077] Furthermore, the third connecting hole 39 and the fourth connecting hole 26 are threaded holes, and the second connecting member 7 is a screw. The screw of the second connecting member 7 is threaded into the threaded holes of the third connecting hole 39 and the fourth connecting hole 26, so as to realize the detachable connection between the glue scraper head 2 and the glue adapter 3, thereby facilitating the disassembly and replacement of the glue scraper head 2 and realizing the modular installation of the glue scraper head 2.

[0078] Furthermore, the outlet of the adapter adhesive path 31 extends to the second mounting wall 33 to form an adhesive path outlet 310, and the inlet of the adhesive dispensing channel 21 extends to the fifth mounting wall 25 to form an adhesive spraying inlet 27. The adhesive path outlet 310 is connected to the adhesive spraying inlet 27. This structure, while ensuring the modular assembly of the scraper head 2 onto the adhesive adapter 3, also enables communication between the adapter adhesive path 31 and the adhesive dispensing channel 21, allowing the adhesive from the scraper gun body 1 to be introduced into the scraper head 2 via the adhesive adapter 3.

[0079] Furthermore, a valve body docking groove 312 is provided on the third mounting wall 34. The adapter adhesive path 31 passes through the valve body docking groove 312, and the lower part of the valve body 4 is installed in the valve body docking groove 312, so that the adapter adhesive path 31 can be opened or closed by the movement of the valve stem. With the above structure, the opening or closing of the adapter adhesive path 31 can be controlled by the valve body 4. When opened, the adhesive can enter the scraper head 2 for dispensing; when closed, the adapter adhesive path 31 is disconnected, and the scraper head 2 stops dispensing adhesive.

[0080] Furthermore, the third mounting wall 34 has one or more fifth connecting holes 313, and the valve body 4 has one or more sixth connecting holes 41. The fifth connecting hole 313 and the sixth connecting hole 41 are connected to each other, and a third connecting member 8 is detachably installed through the fifth connecting hole 313 and the sixth connecting hole 41.

[0081] Furthermore, the fifth connecting hole 313 and the sixth connecting hole 41 are threaded holes, and the third connecting member 8 is a screw. The screw of the third connecting member 8 is threaded into the threaded holes of the fifth connecting hole 313 and the sixth connecting hole 41, so as to realize the detachable connection between the valve body 4 and the glue adapter 3, thereby facilitating the disassembly and replacement of the valve body 4 and realizing the modular installation of the valve body 4.

[0082] Furthermore, the glue gun body 1 is also provided with a glue filter tank 19, and a glue filter 110 is installed in the glue filter tank 19. The glue filter 110 is located on the path of the glue delivery channel 13. After the glue enters the glue delivery channel 13 from the glue inlet 11, it is filtered by the glue filter 110 and then enters the glue scraper head 2 from the glue adapter 3 for glue dispensing.

[0083] Furthermore, multiple glue inlets 11 are provided, and these multiple glue inlets 11 are respectively opened on the top wall, side wall, and back wall of the glue gun body 1, realizing glue feeding from multiple directions and improving glue feeding efficiency. In daily use, only one glue inlet 11 is kept open, and the other glue inlets 11 can be blocked with plugs 12.

[0084] Furthermore, an adhesive inlet 11 is installed on the adhesive inlet 11, and the adhesive inlet 111 can be connected to an external adhesive inlet device to realize adhesive inlet.

[0085] Furthermore, multiple adhesive delivery channels 13 and multiple transfer adhesive paths 31 are provided. Each adhesive delivery channel 13 is paired with one of the transfer adhesive paths 31, and the multiple adhesive delivery channels 13 are arranged longitudinally and parallel within the glue gun body 1. The glue gun body 1 also has horizontally arranged heating rods 9, staggered with the adhesive delivery channels 13, installed to heat the adhesive within the channels 13, preventing solidification and ensuring smooth flow. Each adhesive delivery channel 13 delivers adhesive to its corresponding transfer adhesive path 31, and then through its corresponding dispensing channel 21 to the glue nozzle 22 for dispensing. The horizontally arranged heating rods 9 are positioned at the same distance from all the adhesive delivery channels 13, evenly dispensing adhesive across all channels 13. This ensures a high degree of temperature uniformity in the adhesive within each channel 13, resulting in a more uniform dispensing speed from each glue nozzle 22.

[0086] Furthermore, the glue gun body 1 is provided with a sixth mounting wall 112 on the same side of the first mounting wall 15. The sixth mounting wall 112 is arranged side by side with the valve body 4, and there is a gap between them. This prevents the valve body 4 from directly contacting the glue gun body, avoids the heat of the glue gun body from being conducted to the valve body 4, reduces the temperature of the valve body cylinder, and extends the service life of the seals inside the valve body.

[0087] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
