Description

Technical Field

[0001] The utility model relates to the technical field of glue discharging devices, in particular to a multi-channel glue discharging structure and a glue discharging device with the same. Background Art

[0002] In the existing production process, in order to improve the production efficiency, multiple cavities are usually arranged in a mold. After injecting glue into the mold, multiple products can be produced simultaneously. During the glue injection process, the glue discharging device used needs to have a multi-channel glue discharging structure.

[0003] However, in the existing glue discharging devices, it is difficult to achieve uniform glue discharging at each glue discharging port for the multi-channel glue discharging structure. Especially for the glue discharging structure with an odd number of glue discharging ports, the arrangement of the feed channels cannot adapt to the layout of the odd number of glue discharging ports. For the products injected with glue through this kind of glue discharging device, the phenomenon of lack of glue is likely to occur, and the quality of the products cannot be guaranteed. In order to achieve the effect of uniform glue discharging at each glue discharging port, it is often necessary to increase the requirements for the glue material, including but not limited to the temperature and viscosity requirements of the glue material, thus increasing the production cost. Moreover, even if the glue material meets all the requirements, the risk of non-uniform glue discharging is still very high. Summary of the Utility Model

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a multi-channel glue discharging structure and a glue discharging device with the same.

[0005] The solution for the utility model to solve its technical problems is as follows:

[0006] A multi-channel glue discharging structure includes:

[0007] A glue discharging main body, which is provided with a feed channel, an adjustment hole, a main channel and a plurality of sub-channels. The main channel extends along a first direction, the feed channel communicates with the middle part of the main channel, the feed channel and the sub-channels both extend along a second direction, the opening directions of the feed channel and the sub-channels are opposite, the plurality of sub-channels respectively communicate with the main channel. One of the sub-channels is an intermediate sub-channel, which is arranged in the middle of the main channel, and the other sub-channels are side sub-channels, which are symmetrically arranged on both sides of the intermediate sub-channel. The adjustment hole extends along a third direction, and the adjustment hole communicates with the intermediate sub-channel. The first direction, the second direction and the third direction are perpendicular to each other in pairs;

[0008] An adjustment rod, which extends along the third direction. One end of the adjustment rod is inserted into the intermediate sub-channel, and the other end extends out of the adjustment hole. The adjustment rod is connected with the adjustment hole through a threaded fit. When the adjustment rod is rotated, the adjustment rod can move along the third direction to adjust the opening degree of the intermediate sub-channel.

[0009] The utility model has at least the following beneficial effects: The utility model reasonably arranges the glue inlet channel, the main flow channel and the shunt channels, and by rotating the adjusting rod, the blocking degree of the end of the adjusting rod to the middle shunt channel can be controlled, so as to realize the adjustment of the opening degree of the middle shunt channel. The operator can adjust and control according to the actual situation. By changing the opening degree of the middle shunt channel, the effect of uniform glue discharge from each shunt channel can be achieved, the influence of factors such as the temperature and viscosity of the glue can be ignored, the production cost can be reduced, and the risk of uneven glue discharge from each shunt channel is greatly reduced.

[0010] As a further improvement of the above technical solution, the adjusting hole has a locking section and a sliding section, the diameter of the sliding section is smaller than that of the locking section, the adjusting rod is provided with a blocking section and an adjusting section, the locking section is connected with the adjusting section by thread fit, the blocking section is slidably connected with the sliding section, the blocking section is inserted into the middle shunt channel, and the end face of the blocking section is matched with the inner side wall surface of the middle shunt channel.

[0011] Since a sliding section is arranged between the locking section and the middle shunt channel, and the aperture of the sliding section is smaller than that of the locking section, and the blocking section is matched with the sliding section, it can avoid the situation that the glue flows out of the adjusting hole on the premise of realizing the front and back adjustment of the adjusting rod, further ensure the uniformity and stability of the glue discharge, and reduce the waste of the glue.

[0012] As a further improvement of the above technical solution, an installation groove is arranged on the outer periphery of the blocking section, and the multi-channel glue discharge structure further includes a sealing strip, and the sealing strip is arranged in the installation groove and contacts with the inner wall surface of the sliding section. The setting of the sealing strip can avoid the situation that the glue flows out of the adjusting hole, reduce the influence of the glue on the control of the adjusting rod, and also avoid the waste of the glue.

[0013] As a further improvement of the above technical solution, there are multiple sealing strips, and there are multiple installation grooves, and the multiple installation grooves are arranged along the extending direction of the blocking section, and the sealing strips are arranged in one-to-one correspondence with the installation grooves. With such a setting, multiple seals are arranged between the inner wall of the adjusting hole and the blocking section, which can further avoid the situation that the glue flows out of the adjusting hole.

[0014] As a further improvement of the above technical solution, the main flow channel penetrates through the two end faces of the glue discharge main body along the first direction, and the multi-channel glue discharge structure further includes a first plug, and the first plug is connected to both ends of the main flow channel along the length direction. With such a setting, it is more beneficial to the opening of the main flow channel and simplifies the production process of the glue discharge main body.

[0015] As a further improvement of the above technical solution, the glue discharging main body further includes a transition flow channel, which extends along the third direction. The glue inlet channel and the main flow channel are communicated through the transition flow channel, and the glue inlet channel and the intermediate flow dividing channel are arranged staggeredly. The staggered arrangement of the glue inlet channel and the intermediate flow dividing channel means that they are not on the same straight line. The glue material entering from the glue inlet channel will not directly flow into the intermediate flow dividing channel, but is transitioned to the main flow channel through the transition flow channel and then flows into the intermediate flow dividing channel, further avoiding the uneven glue discharging of each flow dividing channel.

[0016] As a further improvement of the above technical solution, the transition flow channel extends along the third direction to the side wall surface of the glue discharging main body and is provided with an opening. The multi-channel glue discharging structure further includes a second plug, and the second plug is connected to the opening end of the transition flow channel. With this setting, it is more convenient to open the transition flow channel, and the production and manufacturing process of the glue discharging main body can be simplified.

[0017] As a further improvement of the above technical solution, the multi-channel glue discharging structure further includes a glue discharging nozzle, and the glue discharging nozzle is provided with a glue discharging hole, and the glue discharging hole penetrates through the glue discharging nozzle along the second direction. There are multiple glue discharging nozzles, and the multiple glue discharging nozzles are connected to the outside of the glue discharging main body and are arranged in one-to-one correspondence with the flow dividing channels, and the glue discharging holes are communicated with the corresponding flow dividing channels. The glue discharging nozzle can guide the glue material, making it easier to inject the glue material into the preset position, avoiding the leakage of the glue material, reducing the waste of the glue material, and further improving the uniformity and stability of the glue injection.

With this setting, it is more convenient to replace or repair the glue discharging nozzle in the future, and to a certain extent, the versatility of the multi-channel glue discharging structure is improved.

[0019] A glue discharging device includes the multi-channel glue discharging structure described in any one of the above technical solutions. Since the glue discharging device has a multi-channel glue discharging structure, it can realize multi-position glue discharging, and the glue discharging is uniform, improving the production and manufacturing efficiency and the product quality at the same time.

[0034] Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts all fall within the scope of protection of the present utility model. Each technical feature in the present utility model can be combined interactively on the premise of not conflicting with each other.

[0035] In a first aspect, with reference to Figures 1 to 8 , an embodiment of the present utility model provides a multi-channel glue discharging structure, which can achieve uniform glue discharging at multiple glue discharging ports, thereby improving product quality while improving production efficiency.

[0036] The multi-channel glue discharging structure of this embodiment includes a glue discharging main body 100 and an adjusting rod 200. Among them, the glue discharging main body 100 is provided with a glue inlet channel 110, an adjusting hole, a main flow channel 120, and a plurality of branch flow channels. The main flow channel 120 extends along a first direction, the glue inlet channel 110 extends along a second direction, there are a plurality of branch flow channels, each branch flow channel extends along the second direction, and the adjusting hole extends along a third direction.

[0037] The first direction, the second direction, and the third direction are perpendicular to each other in pairs. Specifically, in this embodiment, for the convenience of description, the left-right direction is set as the first direction, the up-down direction is set as the second direction, and the front-back direction is set as the third direction.

[0038] The glue inlet channel 110 communicates with the middle part of the main runner 120. The sub-runners are arranged along the extending direction of the main runner 120 and are respectively communicated with the main runner 120. The opening direction of the sub-runners is opposite to that of the glue inlet channel 110. Specifically, in this embodiment, the glue inlet channel 110 is arranged to open upward, the sub-runners are arranged to open downward, and the openings of the sub-runners are the glue outlet ports.

[0039] In this embodiment, the number of the sub-runners is odd, such as 3, 5, 7, etc. One of the sub-runners is the middle sub-runner 130, which is arranged in the middle part of the main runner 120 and is connected to the middle part of the main runner 120. The adjusting hole is communicated with the middle sub-runner 130. The remaining sub-runners are side sub-runners 140. The number of the side sub-runners 140 is even, and the side sub-runners 140 are symmetrically arranged on the left and right sides of the middle sub-runner with the middle sub-runner as the axis of symmetry.

[0040] The adjusting rod 200 extends along the third direction and is installed in the adjusting hole. One end of the adjusting rod 200 extends into the middle sub-runner 130 along the adjusting hole, while the other end extends out of the adjusting hole. The adjusting hole can move along the third direction, so as to adjust the opening degree of the middle sub-runner 130.

[0041] Specifically, in this embodiment, the adjusting rod 200 and the adjusting hole are connected by thread fit. The adjusting hole is arranged to open backward, and the middle sub-runner 130 is located at the front end of the adjusting hole. When the operator rotates the adjusting rod 200, the adjusting rod 200 moves in the front-back direction, so that the end of the adjusting rod 200 extending into the middle sub-runner 130 moves forward or backward.

[0042] When the front end of the adjusting rod 200 moves to the position where it abuts against the front wall surface of the middle sub-runner 130, the adjusting rod 200 can block the upper and lower sides of the middle sub-runner 130. At this time, the glue material cannot flow out through the middle sub-runner 130. When the front end of the adjusting rod 200 moves backward to separate from the front wall surface of the middle sub-runner 130, the glue material can flow through the space between the front end of the adjusting rod 200 and the front wall surface of the middle sub-runner 130, so as to flow out through the middle sub-runner 130. When the front end of the adjusting rod 200 continues to move backward until the adjusting rod 200 completely leaves the middle sub-runner 130, the middle sub-runner 130 is in the maximum opening state. At this time, the glue material can flow out through the middle sub-runner 130 at the maximum flow rate.

[0043] It can be understood that after observing the glue outlet conditions of each sub-runner, the operator can make the glue outlet of the two side sub-runners 140 and the middle sub-runner 130 uniform by controlling the position of the adjusting rod 200, that is, the influence of factors such as glue material temperature and viscosity can be ignored, the production cost can be reduced, and the risk of uneven glue outlet of each sub-runner is greatly reduced.

[0044] In some embodiments, the adjusting hole has a locking section 160 and a sliding section 170. The diameter of the sliding section 170 is smaller than that of the locking section 160. The adjusting rod 200 is provided with a blocking section 220 and an adjusting section 210. The diameter of the blocking section 220 is smaller than that of the adjusting section 210. An internal thread structure is provided on the inner wall surface of the locking section 160, and an external thread structure is provided on the outer surface of the adjusting section 210. The internal thread structure and the external thread structure are cooperatively connected to realize the movable connection between the adjusting rod 200 and the inner wall of the adjusting hole. The blocking section 220 is slidably connected to the sliding section 170, and the blocking section 220 is inserted into the intermediate flow channel 130 to adjust the opening degree of the intermediate flow channel 130.

[0045] It can be understood that the internal thread structure and the external thread structure can be locked to each other. After the operator rotates the adjusting rod 200 to an appropriate position, the adjusting rod 200 will not automatically move back and forth, so as to ensure the stability of the glue discharge from each glue outlet during the glue discharging process, further ensure the uniform glue discharge, and ensure the quality of the product.

[0046] Since a sliding section 170 is provided between the internal thread structure and the intermediate flow channel 130, and the aperture of the sliding section 170 is smaller than that of the locking section 160, and the blocking section 220 cooperates with the sliding section 170, it can avoid the situation of glue flowing out of the adjusting hole on the premise of realizing the front-back adjustment of the adjusting rod 200, further ensure the uniformity and stability of the glue discharge, and reduce the waste of glue.

[0047] It can be understood that the end face of the blocking section 220 cooperates with the inner side wall surface of the intermediate flow channel 130. Specifically, in this embodiment, the front end face of the blocking section 220 is an arc surface, and the intermediate flow channel 130 is cylindrical. The arc surface coincides with the side wall surface of the cylinder. When the blocking section 220 moves to the position where its front end face abuts against the front wall surface of the intermediate flow channel 130, the wall surface of the blocking section 220 fits with the side wall surface of the intermediate flow channel 130 to achieve the effect of blocking the glue from flowing out through the intermediate flow channel 130.

[0048] In some embodiments, in order to further avoid the situation of glue flowing out of the adjusting hole, an installation groove 221 is provided on the outer peripheral wall surface of the blocking section 220. The installation groove 221 is annular, and the center of the installation groove 221 is located on the central axis of the blocking section 220. A sealing strip is provided in the installation groove 221, and the sealing strip is also annular. When the blocking section 220 is installed in the sliding section 170, the sealing strip can contact the inner wall surface of the sliding section 170, so as to avoid the glue from flowing out of the adjusting hole.

[0049] In some embodiments, a plurality of mounting grooves 221 are provided on the outer periphery of the blocking section 220. The mounting grooves 221 are arranged along the extending direction of the blocking section 220, that is, arranged in the front-rear direction, and correspondingly, a plurality of sealing strips are also provided. With such a setting, multiple seals are provided between the inner wall of the adjusting hole and the blocking section 220, which can further avoid the situation where the rubber material flows out of the adjusting hole.

[0050] In this embodiment, two mounting grooves 221 are provided, and correspondingly, two sealing strips are also provided. This can well prevent the rubber material from flowing out of the adjusting hole while reducing the processing difficulty of the blocking section 220 and reducing the production cost of the multi-channel rubber discharging structure.

[0051] In this embodiment, an operation groove 230 is provided at the rear end of the adjusting rod 200. The operation groove 230 is used to cooperate with tool components such as a wrench and a handwheel, which is beneficial for the operator to rotate the adjusting rod 200 through the tool component to adjust the opening degree of the intermediate flow channel 130. Moreover, the operation is more convenient and labor-saving.

[0052] In this embodiment, the main flow channel 120 penetrates through the left end face and the right end face of the rubber discharging main body 100. First plugs 121 are respectively provided at the left end and the right end of the main flow channel 120. The first plugs 121 can seal the left and right ends of the main flow channel 120 to avoid the rubber material from flowing out of the left and right ends of the main flow channel 120.

[0053] It can be understood that setting the main flow channel 120 to penetrate through the left end face and the right end face of the rubber discharging main body 100 is more conducive to the opening of the main flow channel 120 and simplifies the production process of the rubber discharging main body 100.

[0054] In this embodiment, the diameter of the first plug 121 is larger than the diameter of the main flow channel 120. First notches for installing the first plugs 121 are respectively provided at the left end and the right end of the main flow channel 120. The diameter of the first notch matches that of the first plug 121. With such a setting, the sealing effect of the first plug 121 on both ends of the main flow channel 120 can be improved, and further avoid the situation where the rubber material flows out of the left and right ends of the main flow channel 120.

[0055] In some embodiments, the rubber discharging main body 100 further includes a transition flow channel 150. The transition flow channel 150 extends in the front-rear direction. The feed flow channel 110 and the main flow channel 120 are connected through the transition flow channel 150. Due to the provision of the transition flow channel 150, the intermediate flow channel 130 is directly connected to the main flow channel 120, and the feed flow channel 110 and the intermediate flow channel 130 are arranged staggeredly, that is, not on the same straight line. The rubber material entering from the feed flow channel 110 will not directly flow into the intermediate flow channel 130, but is transitioned to the main flow channel 120 through the transition flow channel 150 and then flows into the intermediate flow channel 130, further avoiding the situation of uneven rubber discharging from each flow channel.

[0056] In this embodiment, the glue inlet channel 110 is located at the rear side of the middle flow dividing channel 130. The transition flow channel 150 is located above the adjusting hole to avoid the mutual influence between the adjusting rod 200 and the transition flow channel 150.

[0057] In some embodiments, the transition flow channel 150 extends along the third direction to the side wall surface of the glue outlet main body 100 and is provided with an opening on the side wall surface of the glue outlet main body 100. A second plug 151 is provided at the opening position of the transition flow channel 150. The second plug 151 can seal the opening end of the transition flow channel 150 to prevent the glue from flowing out of the opening end of the transition flow channel 150.

[0058] In this embodiment, the transition flow channel 150 is provided with an opening facing forward, and its opening end is located on the front side wall surface of the glue outlet main body 100. The second plug 151 is located at the front end of the transition flow channel 150 and can seal the front end of the transition flow channel 150.

[0059] It can be understood that with such a setting, it is more convenient to open the transition flow channel 150. It can be directly opened backward from the front side wall surface of the glue outlet main body 100, which can simplify the production process of the glue outlet main body 100.

[0060] In this embodiment, the diameter of the second plug 151 is larger than that of the transition flow channel 150. A second notch for installing the second plug 151 is provided at the front end of the transition flow channel 150, and the diameter of the second notch matches that of the second plug 151. With such a setting, the sealing effect of the second plug 151 on the front end of the transition flow channel 150 can be improved, and further, the situation of the glue flowing out of the front end of the transition flow channel 150 can be avoided.

[0061] In some embodiments, the multi-channel glue outlet structure further includes a glue outlet nozzle 300. The glue outlet nozzle 300 is provided with a glue outlet hole 310. The glue outlet hole 310 extends along the second direction and penetrates through both ends of the glue outlet nozzle 300 along the second direction. It can be understood that a plurality of glue outlet nozzles 300 are provided. The plurality of glue outlet nozzles 300 are connected to the outside of the glue outlet main body 100 and are arranged in one-to-one correspondence with the flow dividing channels. The glue outlet hole 310 is communicated with the corresponding flow dividing channel.

[0062] In this embodiment, referring to Figure 1 and Figure 6 , a total of three flow dividing channels are provided, two of which are side flow dividing channels 140. Three glue outlet nozzles 300 are provided, which are respectively installed on the lower side of the glue outlet main body 100 and protrude downward from the lower end surface of the glue outlet main body 100. The glue outlet nozzles 300 are arranged in one-to-one correspondence with the flow dividing channels.

[0063] By providing the glue outlet nozzle 300, it is beneficial for docking with components such as molds that require glue injection, facilitating the glue injection operation. The glue outlet nozzle 300 can guide the glue material, enabling the glue material to be more easily injected into the preset position, avoiding the situation of glue leakage, reducing glue waste, and further improving the uniformity and stability of glue injection.

[0064] In this embodiment, a limiting groove 131 is provided at the lower end of the runner, a limiting block 320 is provided at the upper end of the glue outlet nozzle 300, a connecting block 330 is provided on the outer periphery of the glue outlet nozzle 300, and the outer diameter of the limiting block 320 is smaller than the outer diameter of the connecting block 330. During use, the limiting block 320 of the glue outlet nozzle 300 is snapped into the limiting groove 131, and the connecting block 330 abuts against the lower wall surface of the glue outlet main body 100. A detachable connection between the connecting block 330 and the glue outlet main body 100 can be achieved using connecting members such as screws, thereby realizing the installation of the glue outlet nozzle 300.

[0065] With such a setting, it is more convenient for subsequent replacement or repair of the glue outlet nozzle 300. The size of the glue outlet nozzle 300 below the connecting block 330 can be adjusted according to actual needs, making it more versatile.

[0066] In this embodiment, each glue outlet nozzle 300 is connected to the glue outlet main body 100 using four screws, which can ensure the stability of the connection and installation of the glue outlet nozzle 300, and also ensure the sealing performance between the limiting block 320 and the wall of the limiting groove 131, avoiding the situation where the glue material flows out from the gap between the glue outlet nozzle 300 and the glue outlet main body 100.

[0067] On the other hand, the embodiment of the present utility model also proposes a glue outlet device, which includes the multi-channel glue outlet structure proposed in any one of the embodiments in the first aspect, has multiple glue outlets, and the glue outlet of each glue outlet is uniform, which can improve the product quality while improving the production efficiency.

[0068] During use, by rotating the adjusting rod 200, the distance between the front end surface of the adjusting rod 200 and the front wall surface of the intermediate runner 130 is changed, that is, the opening degree of the intermediate runner 130 can be changed. The operator can adjust the glue output of the intermediate runner 130 in a timely manner according to the actual situation, and the effect of uniform glue output between each runner can be achieved without considering the influence of factors such as hinge temperature and viscosity, greatly reducing the production cost of the product.

[0069] The above has specifically described the preferred embodiments of the present utility model, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent variations or substitutions without departing from the spirit of the present utility model, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
