In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described and will be readily apparent to those of ordinary skill in the art without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.
Furthermore, reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one implementation of the invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.
Referring to fig. 1 to 6, an embodiment of the present invention provides a fabricated glue gun, which includes a gun head assembly 100, a glue storage bin 200 and a driving assembly 300.
The gun head assembly 100 is used for glue discharging and comprises a glue injection pipe 101 and a piston assembly 102 arranged inside the glue injection pipe 101. The glue injection pipe 101 comprises a pressure pipe 101a, a sleeve 101b and a glue injection head 101c, wherein the sleeve 101b and the glue injection head 101c are respectively connected to two ends of the pressure pipe 101 a; the pressure pipe 101a is used for matching with the piston group 102 to form pressure so as to push glue to be extruded from the glue injection head 101 c; the sleeve 101b is positioned at the rear end of the pressure pipe 101a and is used for installing and fixing the glue storage bin 200; the glue injection head 101c is a conical thin tube structure, the caliber of the tail end of the glue injection head is small, and the glue injection head is used for aligning to a part to be glued and extruding glue. The front part of the invention corresponds to the direction of the gun head, namely the direction of the glue injection head 101 c; "rear" corresponds to the direction of the butt, i.e., the direction of drive assembly 300.
Piston set 102 is used to create and build pressure within pressure tube 101a to enable the release of glue, with one end located within pressure tube 101a and capable of relative sliding movement, and the other end extending through sleeve 101b and connected to drive assembly 300 at its rear end.
The driving assembly 300 is connected to an end of the piston assembly 102, and can extrude the piston assembly 102 by using a principle of lever driving, so as to drive the piston assembly 102 to longitudinally slide inside the glue injection pipe 101, thereby forming an extrusion force, and finally realizing glue discharge.
The glue storage bin 200 is a glue storage container with an annular structure, and an annular accommodating space R is formed inside the glue storage container; the inner ring of the glue storage bin 200 is sleeved on the periphery of the sleeve 101b, and the glue storage bin 200 is provided with a glue adding nozzle 201 and a glue discharging nozzle 202 which are respectively communicated with the accommodating space R; glue solution can be injected and supplemented into the accommodating space R of the glue storage bin 200 through the glue adding nozzle 201; the glue nozzle 202 communicates with the inner space of the pressure tube 101a through an adapter tube 203.
Based on the above, the glue storage bin 200 of the present invention has a large cross section, and can temporarily store a large amount of glue solution therein, and can input the glue solution into the inner space of the pressure pipe 101a through the connecting pipe 203; the glue solution entering the pressure tube 101a can flow out from the glue injection head 101c in a pressure environment formed by the extrusion and pushing of the piston group 102, so that glue discharge is realized. Because a large amount of glue solution can be temporarily stored in the glue storage bin 200, the length of the glue injection pipe 101 does not need to be increased (the glue injection pipe 101 is only used for forming a pressure environment, and a small amount of glue solution from the glue storage bin 200 is extruded out), so that the length of the gun head is shortened, and the gun head is more convenient to carry; in addition, as the glue storage bin 200 does not need to be replaced and can be replenished with glue solution at any time only through the glue adding nozzle 201, the work of replacing a glue cylinder is omitted, the waste of resources is avoided, and the sustainability is good.
Further, the pressure tube 101a is provided with a barrier 103 therein in the transverse direction. The partition 103 is located at the front end of the piston group 102, and divides the inner space of the pressure tube 101a into a pressure space M-1 located between the partition 103 and the end face of the piston group 102 and a glue outlet space M-2 located between the partition 103 and the glue injection head 101 c.
The interlayer 103 is provided with a one-way hole 103a, and the one-way hole 103a is a through round hole and can communicate the pressure space M-1 with the glue outlet space M-2. A blocking ball 104 is arranged in the glue outlet space M-2, the blocking ball 104 is a ball body with the outer diameter larger than the inner diameter of the one-way hole 103a, the blocking ball 104 is connected with the piston set 102 through an elastic tension piece 105 penetrating through the one-way hole 103a, and the blocking ball 104 can be extruded and blocked on the one-way hole 103a under the tension of the elastic tension piece 105. The elastic tension member 105 may be an elastic and stretchable flexible rope, or may be an extension spring.
When glue solution from the connecting pipeline 203 is temporarily stored in the pressure space M-1 and the piston assembly 102 is located at the initial rear end position, the distance between the piston assembly 102 and the interlayer 103 is long, and the elastic tension member 105 is in the maximum stretching state, so that the plugging ball 104 can be tightly plugged on the one-way hole 103a under the tension of the elastic tension member 105, the pressure space M-1 and the glue outlet space M-2 are separated, and the glue solution temporarily stored in the pressure space M-1 cannot flow out.
When the piston group 102 slides forwards in the pressure pipe 101a, on one hand, the volume of the pressure space M-1 is gradually reduced by compression, the pressure in the pressure space M-1 is gradually increased, and the mixture of the glue solution and the gas has the tendency of pushing the plugging ball 104 forwards; on the other hand, the distance between the piston assembly 102 and the partition 103 is gradually reduced, the tension of the elastic tension member 105 is also gradually reduced, and therefore the tension constraint of the blocking ball 104 by the elastic tension member 105 is also gradually reduced. Finally, under the simultaneous action of the two factors, the blocking ball 104 can be pushed open by pressure, so that the pressure space M-1 is communicated with the glue outlet space M-2, and therefore, the glue solution temporarily stored in the pressure space M-1 can be extruded into the glue outlet space M-2 and finally extruded from the glue injection head 101 c.
When the piston group 102 returns backwards in a sliding mode, the blocking ball 104 can be blocked on the one-way hole 103a again under the influence of the pulling force of the elastic pulling piece 105 and the pressure reduction in the pressure space M-1; the gradually reduced pressure in the pressure space M-1 can suck the glue solution in the glue storage bin 200 and replenish the glue solution into the pressure space M-1 again for the next cycle of extrusion process.
Further, the outer side wall of the pressure pipe 101a is further provided with an outward extending one-way connector 106 for connecting with one end of the connecting pipe 203, and the glue solution in the glue storage bin 200 can be converged into the pressure space M-1 through the connecting pipe 203.
The one-way connector 106 includes a pipe joint 106a, and an elastic pressing piece 106b and a pressing post 106c provided in the pipe joint 106 a. The pipe joint 106a is integrally formed on the outer side wall of the pressure pipe 101a, and has a flow passage 106a-1 communicating with the pressure space M-1 inside thereof; preferably, the pipe joint 106a is arranged obliquely on the outer side wall of the pressure pipe 101a, and the orientation of the outer end thereof has a component toward the glue storage bin 200.
The flow channel 106a-1 is provided with a control chamber 106a-2 in the middle thereof, and the flow channel 106a-1 is divided into an inner section 106a-11 and an outer section 106a-12 by the control chamber 106 a-2. The control chamber 106a-2 has an inner diameter larger than that of the flow passage 106a-1 and has stepped surfaces 106a-3 formed at both ends, respectively.
The pressing column 106c is a short column structure and is disposed in the control chamber 106 a-2; the inner diameter of the extrusion column 106c is smaller than the control chamber 106a-2 and larger than the outer section 106 a-12; the end of the compression leg 106c corresponding to the outer section 106a-12 is configured as a spherical surface 106c-1 and the end corresponding to the inner section 106a-11 has a securing slot 106 c-2. The crush column 106c can be plugged by its spherical surface 106c-1 at the inner port of the outer section 106 a-12.
The elastic pressing member 106b is a compression spring, one end of which presses the pressing post 106c and is defined in the fixing groove 106c-2 thereof, and the other end of which presses the step surface 106a-3 of the inner section 106 a-11; thus, the resilient extrusion 106b has a tendency to continuously squeeze the compression post 106c against the inner port in the outer section 106 a-12.
The glue nozzle 202 is connected to the outer port of the adapter 106a by an adapter pipe 203.
When the piston set 102 returns backward by sliding, the pressure in the pressure space M-1 will gradually decrease, resulting in inconsistent pressures in the inner section 106a-11 and the outer section 106a-12 (the pressure in the inner section 106a-11 is lower than the pressure in the outer section 106 a-12), at this time, the glue solution in the connecting pipe 203 and the glue storage bin 200 has a tendency to flow toward the pressure space M-1, and therefore, the extruding column 106c can be pushed open, the glue solution can smoothly enter the outer section 106a-12 from the glue storage bin 200 through the connecting pipe 203, and the extruding column 106c is pushed open, and then flows into the pressure space M-1 through the inner section 106 a-11. After the pressures on both sides are almost balanced, the compression legs 106c can be re-plugged against the inner ports of the outer sections 106a-12 under compression by the resilient compression members 106 b.
When the piston assembly 102 is advanced slidably within the pressure tube 101a, the pressure in the pressure space M-1 will gradually increase, causing the pressures in the inner and outer sections 106a-11 and 106a-12 to be inconsistent (the pressure in the inner section 106a-11 is greater than the pressure in the outer section 106 a-12), and the squeeze column 106c can be squeezed more tightly against the inner port of the outer section 106a-12, ensuring that the cement in the connecting tube 203 cannot temporarily enter the inner section 106 a-11.
In summary, when the piston assembly 102 returns backwards, the glue storage bin 200 can replenish the glue solution to the pressure space M-1; when the piston set 102 is pressed forward, the glue solution which is previously gathered into the pressure space M-1 can break the plugging ball 104 and extrude out of the glue injection head 101 c. The continuous glue discharging can be realized by the cyclic reciprocating.
Further, the piston assembly 102 includes a piston post 102a and a push-pull rod 102b connected to each other.
The inner side wall of the pressure pipe 101a is provided with a limit ring 107 having an annular structure. The piston post 102a includes a piston head 102a-1 that fits within the inner diameter of the pressure tube 101a and a guide section 102a-2 that fits within the inner diameter of the stop collar 107, the piston head 102a-1 being located at the forward end of the stop collar 107. The guide segment 102a-2 is a cylindrical structure, and the end thereof is provided with a first screw hole K-1 facing the push-pull rod 102 b.
Push-pull rod 102b includes a piston tail 102b-1 fitted to the inner diameter of pressure tube 101a, a threaded rod 102b-2 threadedly coupled to first threaded bore K-1, and a guide post 102b-3 inserted into sleeve 101b, the outer end of guide post 102b-3 being coupled to drive assembly 300. The piston tail 102b-1 is located at the rear end of the stop collar 107, and the guide post 102b-3 fits within the inner diameter of the sleeve 101b and is able to slide relative thereto.
The periphery of the guide section 102a-2 is sleeved with a reset piece 102c, one end of the reset piece 102c is pressed on the piston tail 102b-1, and the other end of the reset piece 102c is pressed on the limiting ring 107, so that the process of assisting the backward return of the piston group 102 is used, and the reset piece can push the piston group 102 which is pressed forwards to reset backwards. The return member 102c is preferably a compression spring that is nested around the periphery of the guide section 102 a-2.
Furthermore, the end face of the piston head 102a-1 is further fixed with an outward extending rod 102a-3, the rod 102a-3 passes through the one-way hole 103a and the blocking ball 104, the elastic tension member 105 is located at the periphery of the rod 102a-3, and the outer end of the rod 102a-3 is further fixed with a stopper 102 a-4. The rod body 102a-3 has an outer diameter smaller than the one-way hole 103a, and can provide a guiding function for the longitudinal sliding of the blocking ball 104. The stop blocks 102a-4 can limit the sliding range of the blocking ball 104 to ensure that the blocking ball does not fall off.
Further, the driving assembly 300 includes a fixed plate 301 detachably coupled to the end of the casing 101b, a bracket 302 integrally formed on the fixed plate 301, a driving rod 303 coupled to the end of the guide post 102b-3, and a movable grip 304 rotatably disposed on the bracket 302 and having one end hinged to the driving rod 303.
The fixed disk 301 is of an annular structure, a second screw hole K-2 is formed in the fixed disk 301, an external thread matched with the second screw hole K-2 is arranged on the outer side wall of the tail end of the sleeve 101b, and the fixed disk 301 is detachably connected to the rear end of the sleeve 101b through the matching of the second screw hole K-2 and the external thread.
A bracket 302 is integrally formed on the stationary plate 301, preferably in a frame configuration, for mounting the drive rod 303 and the movable finger 304.
The driving rod 303 is a rod-shaped structure, one end of the driving rod 303 is fixed with the ball 303a, and the other end of the driving rod 303 is provided with a handle 303b, so that the driving rod 303 can be directly pulled backwards through the handle 303b, and the return speed of the piston group 102 is increased. The end of the guide post 102b-3 is provided with a socket 102b-4 fitted with a ball 303a, and the ball 303a is embedded in the socket 102b-4 and can move relatively. In addition, the bracket 302 is provided with a guide sleeve 302a which is engaged with the driving rod 303, and the driving rod 303 passes through the guide sleeve 302a and can slide relatively in the longitudinal direction.

Further, the glue storage bin 200 can rotate relatively on the sleeve 101b, and the connecting pipe 203 is a hose. Therefore, after the driving assembly 300 is integrally and rotatably connected to the casing 101b through the thread fit between the fixing plate 301 and the end of the casing 101b, the glue storage bin 200 can be rotated to adjust the spatial orientation of the glue outlet 202 to predict the final orientation to be consistent with the end orientation of the movable grip 304. After the spatial orientation of the glue outlet nozzle 202 is finally determined, the fixed disc 301 can be completely screwed down, the glue storage bin 200 is clamped between the fixed disc 301 and the rear end of the pressure tube 101a, and the position of the glue storage bin 200 is fixed, at this time, the orientation of the glue outlet nozzle 202 is consistent with the orientation of the tail end of the movable gripper 304. Even if the orientation of the glue nozzle 202 in the final fixed state is not consistent with the pipe joint 106a, the glue nozzle 202 and the pipe joint 106a can still be connected through the flexible connecting pipe 203, and the normal use after assembly is not affected.
