The problem that the electric glue injection mechanism 10 in the prior art is limited by the specification of the screw rod 520 and cannot achieve larger rules is solved.
The present utility model proposes an electric glue injection mechanism 10, and the electric glue injection mechanism 10 may be a two-plate type electric glue injection mechanism 10, as shown in fig. 3, or may be a three-plate type electric glue injection mechanism 10, as shown in fig. 1 and 2. The two-plate type electric glue injection mechanism 10 comprises a head plate 100 and two plates 200, wherein a plastic injection cylinder 110 is fixedly arranged on the head plate 100, a glue injection screw 210 is fixedly arranged on the two plates 200, and part of the glue injection screw 210 is positioned in the plastic injection cylinder.
The three-plate type electric glue injection mechanism 10 comprises a head plate 100, two plates 200 and a tail plate 300, wherein the head plate 100, the two plates 200 and the tail plate 300 are arranged on a base 400 at intervals, the positions of the head plate 100 and the tail plate 300 are relatively fixed, and the two plates 200 are movably arranged on the base 400 and can be relatively close to or far from the head plate 100 to realize glue injection or loosening and withdrawing actions.
Further, the driving assemblies 500 are in driving connection with the two boards 200, wherein each group of driving assemblies 500 comprises a motor 510, a screw rod 520 and a screw rod nut 530, the screw rod nuts 530 are fixedly installed on the two boards, one end of the screw rod 520 is in driving connection with an output shaft of the motor 510, the other end of the screw rod 520 is in threaded connection with the screw rod nuts 530, and the motor 510 drives the screw rod 520 to rotate and push the screw rod nuts 530 to move in a direction away from or close to the head board so as to enable the two boards 200 to move along the base 400 relative to the head board 100. Here, the driving assembly 500 is mainly used to provide a main driving force to the two plates 200 to drive the two plates 200 to move along the base 400 relative to the head plate 100. The auxiliary driving mechanism is in driving connection with the two plates 200, where the auxiliary driving mechanism is mainly used for providing an auxiliary driving force for the two plates 200 to assist in pushing the two plates 200 along the base 400 to move relative to the head plate 100, and may be a hydraulic cylinder 600, a cylinder or other driving member, so long as an auxiliary force for assisting in driving the two plates 200 along the base 400 to move relative to the head plate 100 can be provided, which is not limited herein. That is, the auxiliary driving mechanism is mainly used for providing partial injection pressure and dwell pressure, so that the requirement for the main driving force of the driving assembly 500 can be relatively reduced while the accuracy of the electric glue injection mechanism 10 is ensured, that is, the specification and model of the screw rod 520 can be relatively reduced, and the production cost of the electric glue injection mechanism 10 is reduced. And when the specification and the model of the screw rod 520 of the driving assembly 500 are fixed, the specification of the electric glue injection mechanism 10 can be designed to be larger, the application range is wide, and the cost is reduced. And the auxiliary driving mechanism can provide the pressure maintaining pressure, and the motor 510 does not need to continuously run in the pressure maintaining process, so that the running cost of the electric glue injection mechanism 100 is reduced.
Preferably, the auxiliary driving mechanism can select a hydraulic oil cylinder 600, the hydraulic oil cylinder 600 is powered by an independent hydraulic oil circuit system to generate partial glue injection force, in the double-screw rod 520 or multi-screw rod 520 structure, if one of the servo motors 510 driving the screw rods 520 is accidentally powered off and loses power, the screw rods 520 without power failure continue to be driven, and at the starting interval of a mechanism protection program, the hydraulic thrust generated by the hydraulic oil cylinder 600 can effectively prevent the situation that the double-screw rod 520 or the multi-screw rod 520 is out of synchronization due to inertia to a certain extent, so that the phenomenon of locking of the mechanism is avoided, and the safety of key parts such as the screw rods 520 is protected.
In terms of operational safety, when a phenomenon of out-of-control (galloping) of the servo motor 510 occurs due to problems of operation, setting, or malfunction, etc., mechanical impact caused by the out-of-control (galloping) of the high speed can be effectively avoided due to the buffering effect of the hydraulic pressure of the hydraulic cylinder 600, thereby protecting the safety of mechanical parts.
In one embodiment, as shown in fig. 3, the structure of the electric glue injection mechanism 10 is illustrated as a two-plate type double-wire rod driving electric glue injection mechanism 10. The two-plate type double-screw driving electric glue injection mechanism 10 takes two main parts of a head plate 100 and a two plate 200 as main bodies, and uses a screw rod 520 and a screw rod nut 530 to connect the two main parts in series to form a glue injection structure; the head plate 100 is used for fixing the injection molding cylinder 110 and is connected with the injection table moving mechanism and the screw nut 530; the two plates 200 are used for fixing the screw 520 and the motor 510 driving the screw 520 to perform the glue injection action. The lead screw nut 530 is fixed to the head plate 100, the lead screw 520 and the motor 510 are connected in a driving manner by a timing pulley 540 and a timing belt 550, and the motor 510 is fixed to the two plates 200. The cylinder body 610 of the hydraulic cylinder 600 is fixedly connected with the head plate 100, and the pull rod 620 of the hydraulic cylinder 600 is connected with the two plates 200.
In this embodiment, the number of the hydraulic cylinders 600 is two, the cylinder bodies 610 of the two hydraulic cylinders 600 are symmetrically fixed on the left and right sides of the head plate 100, and correspondingly, the two pull rods 620 are correspondingly disposed on the left and right sides of the two plates 200, so that the auxiliary pulling force applied to the two plates 200 is more uniform. When the electric glue injection mechanism 10 performs the glue injection action, the motor 510 rotates to drive the screw rod 520 to rotate, and meanwhile, the screw rod 520 pulls the two plates 200 to move towards the head plate 100, the cylinder 610 and the pull rod 620 of the hydraulic cylinder 600 do piston movements for pulling the two plates 200 to assist, and the maximum glue injection pressure of the electric glue injection mechanism 10 is properly improved under the condition that the structure of the driving assembly 500 is unchanged. Meanwhile, in pressure maintaining, the pressure maintaining can be performed through the hydraulic oil cylinder 600, so that the motor 510 does not need to be started, and the cost is saved.
In other embodiments, the rod 620 may be fixed to the head plate, and the cylinder 610 may be fixed to the two plates, which is not limited herein.
Further, the hydraulic ram 600 may be designed as a separate component. In this way, the hydraulic cylinder 600 is more convenient to repair and replace. And the maximum glue injection pressure of the electric glue injection mechanism 10 can be properly increased by properly replacing the hydraulic cylinder 600 without changing the main body structure. Specifically, taking the case that the cylinder body 610 of the hydraulic cylinder 600 is fixed on the head plate 100 and the other is fixed on the two plates 200 as an example, the side wall of the cylinder body 610 may be directly welded and fixed on the side wall of the head plate 100, a positioning bump is convexly arranged on the side wall of the two plates 200, and one end of the pull rod 620 far away from the outside of the cylinder body 610 is penetratingly fixed in the positioning bump, so as to ensure the reliability of the movement between the connecting rod and the cylinder body 610.
In one embodiment, as shown in fig. 1 and 2, the structure of the electric glue injection mechanism 10 is illustrated by taking the structure of the three-plate type double screw 520 driving the electric glue injection mechanism 10 as an example. The three-plate type double-screw 520 driving electric glue injection mechanism 10 takes three main components of a head plate 100, a two-plate 200 and a tail plate 300 as main bodies, and the three main components are connected in series by screw 520 and screw nut 530 to form a glue injection structure; the head plate 100 is used for fixing a plastic injection cylinder 110; the two plates 200 are used for fixing the lead screw nuts 530, and the tail plate 300 is used for mounting and fixing the driving assembly 500. The lead screw nut 530 is fixed to the head plate 100, and the lead screw 520 and the motor 510 are in transmission connection with the timing belt 550 through a pulley 540.
In one embodiment, the moving direction of the two plates 200 is defined as a front-back direction, a direction perpendicular to the moving direction is defined as a left-right direction, the number of the hydraulic cylinders 600 is 2N, N is a positive integer, and the plurality of hydraulic cylinders 600 are separately disposed on the left and right sides of the glue injection screw 210.
It is understood that the greater the number of hydraulic cylinders 600, the better the effect of the auxiliary driving force. Generally, 1, 2, 3, 4 or more hydraulic rams 600 may be used. In this embodiment, in order to make the auxiliary driving force received by the two plates 200 more uniform and make the reliability higher, the number of the hydraulic cylinders 600 is an even number, such as 2, 4, 6, etc., and symmetrically disposed on the left and right sides of the glue injection screw 210. As shown in fig. 2 and 3, the hydraulic cylinder 600 is provided at both left and right sides of the glue injection screw 210. As shown in fig. 1, the hydraulic cylinders 600 are four arranged on the left and right sides of the glue injection screw 210, so that the hydraulic cylinders 600 are designed to apply an auxiliary driving force to the two plates 200, so that the left and right sides of the two plates 200 are subjected to more uniform acting force of the hydraulic cylinders 600, and the reliability is higher.
In one embodiment, the driving assemblies 500 are two groups, and the two plates are provided with 2 screw nuts 530,2 extending in the front-rear direction, and the screw nuts 530 are respectively disposed on the left and right sides of the glue injection screw 210.
Alternatively, in the present embodiment, the driving assemblies 500 are two, that is, the two-plate type electric glue injection mechanism 10 is driven to move by the double screw 520. Specifically, two driving assemblies 500 are defined as a first driving assembly 500 and a second driving assembly 500, wherein the first driving assembly 500 includes a first screw 521, a first motor 511 and a first screw nut 531 connected to the first screw 521 in a transmission manner, the second driving assembly 500 includes a second screw, a second motor 512 connected to the second screw in a transmission manner, and a second screw nut 531, the first screw 521 and the second screw are symmetrically disposed on the two plates 200 (taking the two-plate type electric glue injection mechanism 10 as an example), and the head plate 100 and the two plates 200 are cooperatively connected through the first screw 521, the second screw, the first screw nut 531 and the second screw nut to form a glue injection structure in series, the two plates 200 are driven by the double motor 510, the double screw 520 and the auxiliary driving mechanism to move towards the head plate direction, so as to achieve the glue injection purpose. Compared with the driving of the single-filament rod 520, the driving of the double-filament rod 520 has relatively smaller requirements on the specification and model of the filament rod 520 when the injection pressure of the electric glue injection mechanism 10 is constant, and is beneficial to the large-scale design of the electric glue injection mechanism 10.
Further, the motor 510 drives the screw 520 to rotate through a belt wheel 540-belt transmission manner, so that the two plates 200 fixing the screw nut 530 realize reciprocating motion. And a synchronizing wheel is provided on the pulley 540 of the screw 520 and is connected by a pulley 540-belt transmission. When the transmission of the screw rod 520 is different, the action of the synchronous wheel and the belt can forcedly adjust the movement of the screw rod 520 to be consistent.
In one embodiment, as shown in fig. 1, there are 4 hydraulic cylinders 600, and the upper and lower sides of each screw nut 530 are respectively provided with one hydraulic cylinder 600; each screw nut 530 is disposed on the same plane as the axis of the hydraulic cylinder 600 disposed on the upper and lower sides of the screw nut 530.
In this embodiment, taking the electric glue injection mechanism 10 as a three-plate type electric glue injection mechanism 10 and a double screw rod 520 driving as an example, the glue injection screw rod 210 is fixedly installed at the middle part of the two plates 200, 4 hydraulic cylinders 600 are rectangular and distributed around the glue injection screw rod 210, and the cylinder body 610 of the hydraulic cylinder 600 is fixed on the two plates 200 and extends along the axial direction of the glue injection screw rod 210. One of the screw nuts 530 is defined as a first screw nut 531, and both upper and lower ends of the first screw nut 531 have a hydraulic cylinder 600 extending in an axial direction of the glue injection screw 210. Specifically, the cylinder body 610 of the hydraulic cylinder 600 is fixed to the two plates, one end of the rod 620 is connected to the piston of the cylinder body 610, and the other end is fixed to the head plate 100, and the moving direction of the hydraulic cylinder 600 is identical to the moving direction of the two plates 200. When glue is injected, the tensile force of the 4 hydraulic cylinders 600 on the two plates 200 is uniform and reliable, so that the glue injection precision of the electric glue injection mechanism 10 is ensured. Meanwhile, in the present embodiment, the hydraulic cylinder 600 uses the pull rod 620 as a piston rod, and uses the guiding position of the two plates 200 as the cylinder 610, so as to form the whole hydraulic cylinder 600 structure, the whole electric glue injection mechanism 10 has compact structure, no extra parts are required to be added, and the overall size of the electric glue injection mechanism 10 has no obvious increase in length and width compared with the structure without the hydraulic cylinder 600. And the axes of the first screw rod 521 and the second screw rod are respectively on the same plane with the axis of the hydraulic cylinder 600 (the axes of the upper hydraulic cylinder 600 and the lower hydraulic cylinder 600 and the axis of the first screw rod 521 are on the same plane), so that the bearing effect is good, the screw rod 520 can be effectively protected, the unbalanced load force borne by the screw rod 520 is reduced, and the service life of the screw rod 520 is prolonged.
In one embodiment, the two sides of the glue injection screw 210 are provided with the hydraulic cylinder 600, and the hydraulic cylinder 600 is disposed outside the screw nut 530.
In the present embodiment, as shown in fig. 2, the hydraulic cylinder 600 is provided outside the lead screw nut 530, and thus, the installation of the hydraulic cylinder 600 appropriately increases the maximum glue injection pressure of the electric glue injection mechanism 10 without making a major structural change. Specifically, taking the case that the cylinder body 610 of the hydraulic cylinder 600 is fixed on the head plate 100 and the other is fixed on the two plates 200 as an example, the side wall of the cylinder body 610 can be directly welded or clamped on the side wall of the head plate 100, a positioning bump is convexly arranged on the side wall of the two plates 200, and one end of the pull rod 620 far away from the outside of the cylinder body 610 is penetratingly fixed in the positioning bump, so as to ensure the reliability of the movement between the connecting rod and the cylinder body 610.
Further, the hydraulic ram 600 may be designed as a separate component. Thus, the hydraulic cylinder 600 is more convenient to install, maintain and replace.
In one embodiment, the electric glue injection mechanism 10 further includes at least two guide posts 700, two ends of the guide posts 700 are respectively fixed to the head board 100 and the tail board 300, the two boards 200 are movably mounted to the guide posts 700, and the driving assembly 500 and the auxiliary driving assembly 500 are used for driving the two boards 200 to perform linear motion along the axial direction of the guide posts 700.
Optionally, the head plate 100, the two plates 200 and the tail plate 300 are connected in series by the guide post 700, the positions of the head plate and the tail plate 300 are relatively fixed, and the two plates 200 can move linearly along the axial direction of the guide post 700. The screw 520 and the motor 510 are fixed to the tail plate 300. When the electric glue injection mechanism 10 performs the glue injection action, the screw rod 520 rotates, and meanwhile, the screw rod 520 pushes the screw rod nut 530 to move along the axial direction of the guide post 700, and the hydraulic oil cylinder 600 applies a pulling force or pushing force which is set in the same direction as the acting force applied to the two plates 200 by the screw rod, so as to assist in driving the two plates 200 to move along the axial direction of the guide post 700, and the movement of the two plates 200 takes the guide post 700 as a guide, so that the bearing load of the screw rod nut 530 in the process of screw rod glue injection or loosening can be reduced, and the protection of parts is facilitated.
It should be noted that, the hydraulic cylinder 600 may be disposed at a peripheral side of the guide post 700, or may replace one or more positions of the guide post 700, so as to apply an auxiliary force to the movement of the two plates 200, and simultaneously provide a guiding force to the two plates, so as to reduce the bearing load of the screw nut 530 in the process of injecting or loosening the screw, and be beneficial to protecting parts. Specifically, taking the guide posts 700 as 4 guide posts arranged in a matrix as an example, two guide posts 700 arranged diagonally are replaced by the hydraulic cylinder 600, that is, the pull rod 620 is used as a piston rod, and the guiding position of the two plates 200 is used as the cylinder 610, so as to form the whole hydraulic cylinder 600 structure. Thus, the electric glue injection mechanism 10 has a compact structure, and the injection pressure is increased without adding extra parts, so that the overall size of the mechanism is not obviously increased compared with the structure without the hydraulic cylinder 600.
In an embodiment, the pull rod 620 is in a round rod shape, two ends of the axial direction of the cylinder body are penetrated, the cylinder body 610 is provided with a piston cavity, a part of the pull rod 620, which is arranged in the piston cavity, is convexly provided with an annular bump, the pull rod 620 is slidably mounted in the piston cavity, the piston cavity is separated into two sealing cavities, one end of the pull rod 620 is fixed on the head plate 100, the tail plate 300 is provided with a sliding channel for the pull rod 620 to be inserted in corresponding to the position of the pull rod 620, and the other end of the pull rod is slidably arranged in the sliding channel, so that the hydraulic cylinder 600 can also play a guiding role.
Further, the base 400 is provided with a sliding rail, and the bottoms of the head plate 100, the two plates 200 and the tail plate 300 are respectively provided with a linear guide rail sliding block for being matched with the sliding rail.
