Description

Technical Field

[0001] The utility model relates to the technical field of glue sprinkling, in particular to a glue sprinkling head for a glue sprinkling machine which is anti-clogging. Background Art

[0002] The glue spraying head used in the glue spraying machine is connected to the glue spraying machine in a specific way, usually through the glue inlet hole and the glue delivery pipe of the glue spraying machine. There are multiple glue storage chambers inside the glue spraying head. After the glue enters the glue spraying head from the glue delivery pipe, it will flow through these glue storage chambers in turn, and finally be evenly sprayed out from the glue outlet hole.

[0003] When the existing glue spraying head is working, the glue is introduced from the outside into the glue storage bin through the glue delivery pipe. However, during the transportation process, in order to ensure the smooth flow of the glue, the air in the glue storage bin must be exhausted from the glue spraying head. This exhaust process causes the glue spraying to start from the center of the glue storage bin first, while the glue spraying on the two sides starts relatively later. During the mobile glue spraying process, this uneven glue spraying pattern forms a wavy covering effect, which not only affects the product quality, but also often requires additional re-spraying operations to correct it. This undoubtedly increases the operation steps and reduces the efficiency and convenience of the glue spraying head. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide a glue spraying head for a glue spraying machine that is anti-clogging, so as to solve the technical problem that glue spraying often starts from the center part of the glue storage bin first, while glue spraying on both sides starts relatively late, resulting in the formation of a wavy spraying structure, which reduces the efficiency and convenience of using the glue spraying.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a glue spraying head for a glue spraying machine with an anti-clogging function, comprising a glue spraying head main body, a diverter trough main body is arranged inside the glue spraying head main body, the diverter trough main body comprises a glue delivery main trough and a glue storage bin, two first diverter troughs are arranged at the bottom end of the glue delivery main trough, two second diverter troughs are arranged at the other end of the first diverter trough, and a diverter mechanism is arranged at the connection between the first diverter trough and the second diverter trough;

[0006] The diversion mechanism comprises a mounting hole, a rotating rod is arranged inside the mounting hole, a diversion block is arranged on the rotating rod, and a handle is arranged at one end of the rotating rod.

[0007] By adopting the above technical solution, the amount of colloid diverted to the second diverter grooves on both sides can be adjusted by rotating the diverter block. At the same time, this adjustment enables the second diverter grooves close to the outside to be filled with more colloid, thereby improving the filling speed of the colloid on both sides inside the glue storage bin.

[0008] Furthermore, the rotating rod is rotatably connected to the mounting hole via a resistance bearing.

[0009] By adopting the above technical solution, the rotating rod can rotate smoothly in the mounting hole. This design allows the operator to easily adjust the position of the diverter block through the handle, thereby controlling the flow direction and distribution of the colloid.

[0010] Furthermore, the cross section of the diverter block is in a triangular structure, and first rounded corners are formed at the edges and corners of the diverter block.

[0011] By adopting the above technical solution, the colloid can be effectively dispersed into the second diversion grooves on both sides when flowing through the diversion block, and the triangular structure ensures the uniformity and stability of the colloid diversion.

[0012] Furthermore, a plurality of anti-slip teeth are arranged on the outer side of the handle, and the plurality of anti-slip teeth are arranged in an equidistant ring shape along the central axis of the handle.

[0013] By adopting the above technical solution, the anti-slip teeth increase the friction between the operator's hand and the handle, making it more stable and less likely to slip when turning the handle, which is especially important for operations that require precise control of the position of the rotating rod and the diverter block.

[0014] Furthermore, the connection between the main glue delivery groove and the first diverter groove, and the connection between the first diverter groove and the second diverter groove are both formed with second rounded corners, and the bending parts of the first diverter groove and the second diverter groove are both formed with second rounded corners.

[0015] By adopting the above technical solution, the second rounded corner helps to reduce the resistance of the colloid when it flows through these connections, ensuring that the colloid can flow smoothly from the main glue delivery groove into the first branch groove and further into the second branch groove.

[0016] Furthermore, the glue spraying head body includes a first mounting plate and a second mounting plate, and the first mounting plate and the second mounting plate are connected by bolts.

[0017] By adopting the above technical solution, the two parts are installed and connected by bolts, which ensures the stability and reliability of the rubber spraying head structure. The use of bolts for connection can facilitate installation, disassembly and maintenance.

[0018] Furthermore, a plurality of glue outlet pipes are provided at the bottom ends of the first mounting plate and the second mounting plate, and the plurality of glue outlet pipes are linearly arranged at equal distances along the length line of the glue spraying head body.

[0019] By adopting the above technical solution, multiple glue outlet pipes enable the colloid to flow out from multiple positions at the same time, thereby increasing the coverage area and uniformity of the glue spraying.

[0020] Furthermore, the top ends of the first mounting plate and the second mounting plate are provided with connecting ports, and the top ends of the connecting ports are threadedly connected with a rubber delivery hose.

[0021] By adopting the above technical solution, a convenient interface is provided for connecting the glue delivery hose, ensuring that the colloid can be smoothly transported from the outside to the inside of the glue spraying head.

[0022] Furthermore, the rubber delivery pipe, the connecting port, the main rubber delivery trough, the first diverter trough, the second diverter trough and the rubber storage bin are connected.

[0023] By adopting the above technical solution, it is ensured that the colloid can smoothly flow from the rubber delivery pipe through the connecting port, the main rubber delivery groove, the first diversion groove and the second diversion groove, and finally enter the rubber storage bin for storage or further distribution.

[0024] Furthermore, the rotating rod and the diverter block are both made of stainless steel.

[0025] By adopting the above technical solution, the stainless steel material has excellent corrosion resistance, can maintain the stability and functionality of the material for a long time during the glue spraying process, and is not easily damaged by corrosion from the chemical components in the colloid.

[0026] In summary, the utility model mainly has the following beneficial effects:

[0027] 1. The utility model can adjust the amount of colloid diverted to the second diverter slots on both sides through the diverter mechanism and the rotation of the diverter block. At the same time, this adjustment enables the second diverter slots close to the outside to receive more colloid, thereby accelerating the filling speed of the colloid on both sides of the glue storage bin. Since the colloid flows more to the outside, the filling speed of the colloid in the second diverter slot close to the inside will be relatively reduced. This differentiated filling speed is conducive to adjusting the formation amplitude of the wave-like effect during the glue spraying process, reducing the operation of re-spraying, and improving the convenience of using the glue spraying head;

[0028] 2. The utility model sets a second rounded corner, which helps to reduce the resistance of the colloid when it flows through the connection or bend of the trough body, so that the colloid can flow more smoothly. This smooth colloid flow helps to ensure the continuity and uniformity of the glue pouring process. At the same time, the second rounded corner can also prevent the colloid from generating eddy currents or accumulation at these positions, thereby avoiding defects or inconsistencies in the glue pouring process, which helps to improve the quality and reliability of the glue pouring products.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0035] The following describes an embodiment of the utility model based on its overall structure.

[0036] Embodiment 1:

[0037] A glue spraying head for a glue spraying machine with an anti-clogging function, such as Figure 1-Figure 4 As shown, it includes a glue spraying head body 1, a diverter trough body 2 is arranged inside the glue spraying head body 1, and the diverter trough body 2 includes a glue delivery main trough 201 and a glue storage bin 204. Two first diverter troughs 202 are arranged at the bottom end of the glue delivery main trough 201, and two second diverter troughs 203 are arranged at the other end of the first diverter trough 202. A diverter mechanism 3 is arranged at the connection between the first diverter trough 202 and the second diverter trough 203;

[0038] The diversion mechanism 3 includes a mounting hole 301, a rotating rod 302 is arranged inside the mounting hole 301, a diversion block 303 is arranged on the rotating rod 302, and a handle 304 is arranged at one end of the rotating rod 302. By rotating the diversion block 303, the amount of colloid diverted to the second diversion grooves 203 on both sides can be adjusted. At the same time, this adjustment enables the second diversion grooves 203 close to the outside to be filled with more colloid, thereby improving the filling speed of the colloid on both sides of the glue storage bin 204. Since the colloid flows more to the second diversion grooves 203 on the outside, the filling speed of the colloid close to the inside is relatively reduced, which is conducive to adjusting the amplitude of the wave-like effect formed during the glue spraying process, so that the glue spraying is more uniform.

[0039] See also Figure 3 , Figure 4The rotating rod 302 is rotatably connected to the mounting hole 301 through a resistance bearing, thereby realizing smooth rotation of the rotating rod 302 in the mounting hole 301. This design allows the operator to easily adjust the position of the diverter block 303 through the handle 304, thereby controlling the flow direction and distribution of the colloid. At the same time, the use of the resistance bearing also increases the stability and accuracy of the rotation of the rotating rod 302, ensuring that the diverter block 303 can accurately stay in the required position, thereby realizing precise control of the amount of colloid inside the second diverter slots 203 on both sides, which helps to improve the uniformity and quality of glue spraying, reduce the need for re-spraying operations, and improve work efficiency.

[0040] See also Figure 3 , Figure 4 The cross-section of the diverter block 303 is triangular in structure, and first rounded corners 401 are formed at the corners of the diverter block 303, so that the colloid can be effectively dispersed into the second diverter grooves 203 on both sides when flowing through the diverter block 303. The triangular structure ensures the uniformity and stability of the colloid diversion. At the same time, first rounded corners 401 are formed at the corners of the diverter block 303. This design helps to reduce the resistance of the colloid when flowing through the corners and prevent the colloid from accumulating at the corners. The existence of the first rounded corners 401 allows the colloid to pass through the diverter block 303 more smoothly, further improving the uniformity and quality of the glue spraying.

[0041] See also Figure 3 , Figure 4 A plurality of anti-skid teeth 305 are provided on the outer side of the handle 304. The plurality of anti-skid teeth 305 are arranged in an equidistant ring along the central axis of the handle 304. The anti-skid teeth 305 increase the friction between the operator's hand and the handle 304, making it more stable and less likely to slip when the handle 304 is turned. This is particularly important for operations that require precise control of the positions of the rotating rod 302 and the diverter block 303. At the same time, the plurality of anti-skid teeth 305 not only make the anti-skid effect more uniform, but also enhance the overall aesthetics of the handle 304, and help the operator feel a more stable torque feedback when turning the handle 304, thereby further improving the accuracy and comfort of the operation.

[0042] Second embodiment:

[0043] See also Figure 1 , Figure 2The connections between the main glue delivery groove 201 and the first branch groove 202, and between the first branch groove 202 and the second branch groove 203 are all formed with second fillets 402, and the bending parts of the first branch groove 202 and the second branch groove 203 are all formed with second fillets 402. The second fillets 402 help to reduce the resistance of the colloid when it flows through these connections, ensuring that the colloid can smoothly flow from the main glue delivery groove 201 into the first branch groove 202, and then further into the second branch groove 203. At the same time, this can avoid the generation of eddy currents or accumulation of the colloid at the bending parts, ensuring that the colloid can be evenly and stably distributed in the entire branch groove. This design helps to improve the uniformity and quality of glue spraying, and reduce glue spraying defects caused by poor colloid flow.

[0044] See also Figure 1 , Figure 2 The glue spraying head body 1 includes a first mounting plate 101 and a second mounting plate 102, and the first mounting plate 101 and the second mounting plate 102 are installed and connected by bolts 106. The two parts are installed and connected by bolts 106, which ensures the stability and reliability of the glue spraying head structure. The use of bolts 106 for connection can facilitate installation, disassembly and maintenance. At the same time, the bolts 106, as connecting parts, can provide sufficient connection strength to ensure that the first mounting plate 101 and the second mounting plate 102 will not move or loosen relative to each other during the glue spraying process, thereby ensuring the accuracy and stability of glue spraying.

[0045] See also Figure 1 , Figure 2 A plurality of glue outlet pipes 105 are arranged at the bottom ends of the first mounting plate 101 and the second mounting plate 102. The plurality of glue outlet pipes 105 are arranged equidistantly linearly along the length line of the glue spraying head body 1. The plurality of glue outlet pipes 105 enable the glue to flow out from multiple positions at the same time, thereby increasing the coverage area and uniformity of the glue spraying. At the same time, the equidistant linear arrangement ensures that the amount of glue flowing out of each glue outlet pipe 105 is relatively uniform, thereby avoiding the situation where there is too much or too little local colloid, and further improving the uniformity and quality of the glue spraying.

[0046] See also Figure 1 , Figure 2 , Figure 3 A connecting port 103 is provided at the top of the first mounting plate 101 and the second mounting plate 102, and a rubber delivery pipe 104 is threadedly connected to the top of the connecting port 103, providing a convenient interface for connecting the rubber delivery pipe 104, ensuring that the colloid can be smoothly transported from the outside to the inside of the glue spraying head. At the same time, the top of the connecting port 103 is connected to the rubber delivery pipe 104 by a threaded connection. This connection method is both firm and reliable, and can effectively prevent the leakage of the colloid during the transportation process, thereby ensuring the continuity and stability of the glue spraying work.

[0047] See also Figure 1 , Figure 2 , Figure 3 The glue delivery pipe 104, the connecting port 103, the main glue delivery groove 201, the first branch groove 202, the second branch groove 203 and the glue storage bin 204 are connected, ensuring that the colloid can smoothly flow from the glue delivery pipe 104 through the connecting port 103, the main glue delivery groove 201, the first branch groove 202 and the second branch groove 203, and finally enter the glue storage bin 204 for storage or further distribution. At the same time, this connectivity design also helps to balance the pressure and flow distribution of the colloid inside the glue spraying head, so that the colloid can be more evenly distributed to each glue outlet pipe 105, thereby improving the uniformity and consistency of glue spraying.

[0048] See also Figure 3 , Figure 4 The materials of the rotating rod 302 and the diverter block 303 are both stainless steel. The stainless steel material has excellent corrosion resistance and can maintain the stability and functionality of the material for a long time during the glue pouring process. It is not easily corroded and damaged by the chemical components in the colloid. At the same time, the stainless steel material also has good mechanical strength and wear resistance, and can withstand the mechanical stress and friction during the glue pouring process, ensuring the long-term stability and life of the rotating rod 302 and the diverter block 303.

[0049] The implementation principle of the utility model is as follows: first, the first mounting plate 101 and the second mounting plate 102 are installed and connected by bolts 106, and the connection port 103 is connected to the glue delivery pipe 104 by threaded connection. When the glue spraying head is used for adjacent angle operation, the external colloid is transported to the inside of the glue spraying head main body 1 through the glue delivery pipe 104 by the conveying force of the spiral extrusion mechanism or the pump body, and the colloid passes through the glue delivery main groove 201, the first diversion groove 202 and the second diversion groove 203 in sequence until the colloid is diverted into four parts and poured into the inside of the glue storage bin 204. As the pressure inside the glue storage bin 204 gradually increases, when it exceeds the glue discharge pressure, the colloid inside the glue storage bin 204 is transported out of the glue spraying head main body 1 through the glue discharge pipe 105, and the glue spraying operation is completed;

[0050] When the colloid is transported to the glue storage bin 204, the air on both sides of the second diverter trough 203 at the glue delivery outlet of the glue storage bin 204 is gradually squeezed outward, and the colloid near the outlet will first be discharged through the corresponding glue outlet pipe 105, while the colloid far from the outlet needs to squeeze out the internal air first before it can be discharged through the corresponding glue outlet pipe 105, resulting in a wave-like structure in the glue spraying process;

[0051] Firstly, by manually twisting the handle 304, the rotating rod 302 is driven to rotate inside the mounting hole 301 through the resistance bearing, and the diverter block 303 is driven to rotate at the same time, and the colloid is dispersed into two parts by using the triangular structure. By rotating the diverter block 303, the amount of colloid diverted to the inside of the second diverter grooves 203 on both sides can be adjusted, and the second diverter grooves 203 close to the outside can be filled with more, thereby increasing the filling speed of the colloid on both sides of the glue storage bin 204 and reducing the filling speed of the colloid close to the inside, which is conducive to adjusting the formation amplitude of the wave-like effect, improving the convenience of using the glue spraying head, and thus reducing the repeated spraying operation.

[0052] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.

[0053] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
