The structure of the nozzle 120 is designed based on cooperation with other structures, because in this structure the colloid needs to be scraped off the nozzle 120, so it is set to a protruding rectangular parallelepiped structure. If other cooperating structures change, the structure of the nozzle 120 can also be changed accordingly. A discharge port is provided at the front top of the nozzle 120, and a pre-extrusion port is provided at the rear bottom. A rotary valve hand lever 1232 for controlling the discharge direction is provided between the pre-extrusion port and the discharge port. The rotary valve hand lever 1232 includes a valve that is connected to the nozzle 120 and can change direction, and a rocker connected to the valve and fixed to the frame; the pre-extrusion port is used to observe the melting condition of the colloid before the formal discharge. In addition, when the color of the colloid used in the bottle cap changes, it can also be used to observe whether the colloid of other colors in the front is completely discharged.
[0022] See Figure 2 and Figure 3 and Figure 6 and Figure 7The present design also includes a bottle-glue assembly device 2, which includes a chassis 21 fixed to the frame, with a first rotating drum 22 provided in the center of the chassis 21; a first rotating disk 23 rotating coaxially with the first rotating drum 22 is provided above the chassis 21, and a plurality of first notches 24 cooperating with the bottle caps are evenly provided on the outer edge of the first rotating disk 23; an annular limit plate 25 for preventing the bottle caps from separating upward is fixed on the first rotating drum 22 and located above the first rotating disk 23; a first fixing plate 26 is fixed around the first rotating drum 22 and located above the limit plate, a second fixing plate 29 is fixed on the first rotating drum 22 and provided on the first fixing plate 26, and a top plate 27 is fixed above the first rotating drum 22 and provided on the second fixing plate 29; a protective plate 28 is provided on the side of the chassis 3421 for preventing the bottle caps from flying out and cooperating with the first notch 24; the protective plate 28 is an arc-shaped structure. When the first rotating drum 22 rotates, the first rotating disk 23 is driven, and the annular limiting plate 25, the first fixing plate 26 and the top plate 27 all rotate along with it.
[0023] The first fixed plate 26 is fixed with a plurality of scraper devices, the scraper devices including a scraper rod 261 that passes through the first fixed plate 26 and corresponds to the first recess 24 and can move up and down. The scraper rod 261 is connected to a connector 262 with a diameter larger than the scraper rod 261 and fixed on the second fixed plate 29. The scraper rod 261 is located between the first fixed plate 26 and the connector 262 and is provided with a spring. The spring can be an ordinary compression spring to assist the scraper rod 261 in moving up and down. The interior of the scraper rod 261 is a hollow structure and an air pipe 263 is connected to the connector 262 to communicate with the interior of the scraper rod 261. The connector 26 2 is provided with a roller 264 at the top, and the scraper 261 is mainly used to scrape the melted colloid out of the discharge port of the nozzle 120, and the overall weight of the colloid after scraping can be controlled by setting the speed; the discharge port of the nozzle 120 is located on the path of the bottom end of the scraper 261, and the top plate 27 is provided with a first guide block 271 and a second guide block 272 extending downward. The first guide block 271 is provided above the nozzle 120 and is located on the path of the roller 264. The first guide block 271 extends downward so that the roller 264 also starts to move downward after contacting it, and the scraper 261 originally located above the nozzle 120 is moved downward. The head starts to move downward to contact the upper surface of the nozzle 120, so that the scraper 261 can smoothly scrape off the colloid; the second guide block 272 is provided in the same direction as the rotation direction of the first drum 22 and is located on one side of the first guide block 271. The second guide block 272 extends downward. When the roller 264 touches the second guide block 272 again, it will also move downward. The function of the second guide block 272 is to ensure that the scraped colloid falls smoothly into the bottle cap, because the head of the scraper 261 may move forward with the scraper 261 after scraping off the colloid, and when the colloid falls off from the upper surface of the nozzle 120 and passes through the head wall of the scraper 261 The guidance of the surface will cause it to fall downward, and continuing to move the entire scraper 261 downward to reduce the distance between the head of the scraper 261 and the bottom of the bottle cap can ensure that the colloid does not fall into other positions; the length and width of the first guide block 271 and the second guide block 272 are set according to actual needs and the operating distance of the scraper 261; under normal circumstances, the scraper 261 is fixed to the first fixed plate 26 by the force of the spring against the connecting head 262. When the roller 264 of the connecting head 262 interacts with the first guide block 271 and the second guide block 272, it is subjected to a downward pressure to cause the scraper 261 to move downward. The roller 264 structure is provided to reduce direct friction between the connector 262 and the first and second guide blocks 271 and 272, and to allow the scraper 261 to move downward more smoothly. The air pipe 263 is used to scrape the colloid from the nozzle 120 and then smoothly deliver the colloid into the bottle cap through the instantaneous blowing force of the air pipe 263.
[0024] See Figure 1The present design also provides a transition tray 4 for transitioning the bottle caps to the other side, including a transition plate 41 flush with the chassis 21, a third rotating disk 43 provided on the transition plate 41, and an opening 431 that cooperates with the bottle caps; the function of the transition tray 4 is to transition the bottle caps to another position, and in order to shorten the transportation time, the rotation direction of the third rotating disk 43 of the transition structure design in the present design is opposite to the rotation direction of the first rotating disk 23, so that the bottle caps can take the shortest route to reach another designated position.
[0025] The present invention also provides a die discharge device 3, which includes a base 31 fixed to the frame. In the present invention, the base 31 is a barrel-shaped structure, and the upwardly extending annular wall can play a role of shielding and protection; a second rotating drum 32 is provided in the center of the base 31, and an inner concave curved guide groove (not shown) is provided on the outer wall below the second rotating drum 32. An annular first placement plate 33 is arranged around the second rotating drum 32 and above the guide groove (not shown). The first placement plate 33 rotates synchronously with the second rotating drum 32; an annular bottom plate 34 surrounds the second rotating drum 32. The second rotating drum 32 is provided on the second rotating drum 32 and is flush with the transition plate 41. The bottom plate 34 is provided with a second rotating disk 341. The outer edge of the second rotating disk 341 is provided with a plurality of second notches 342 that cooperate with the bottle caps. An annular second storage tray 35 is provided around the second rotating drum 32 and is located above the second rotating disk 341. An annular third storage tray 36 is provided around the second rotating drum 32 and is provided on the second storage tray 35. A plurality of pressure rods 37 that can move up and down are evenly fixed on the third storage tray 36 and the second storage tray 35. The rear end of each pressure rod 37 is fixed to A spring is provided between and outside the second storage tray 35 and the third storage tray 36. The spring here can be an ordinary compression spring. The front end of each pressure rod 37 passes through the second storage tray 35 and extends downward. The front end of each pressure rod 37 is connected to a pressing mold 371. The pressure rods 37 between the pressing mold 371 and the second storage tray 35 are all covered with springs. The spring here can be an ordinary compression spring. The bottom of the pressing mold 371 is a mold structure that matches the inner bottom of the bottle cap, so that the colloid is pressed completely to fit the bottle cap. A plurality of vertically movable push rods 331 are evenly fixed on the storage tray 33. The top end of each push rod 331 passes through the bottom plate and can extend out of the bottom plate to face the die 371. The lower end of each push rod 331 is connected to a connecting shaft 332. The other end of each connecting shaft 332 is connected to a cam 333. The cam 333 is fixed in a guide groove (not shown). The push rod 331 moves forward along the guide groove (not shown) through the cam 333. The guide groove (not shown) is designed with an undulating curved structure according to actual needs to control the up and down movement of the push rod 331.
[0026] An arc-shaped baffle 42 is provided on the transition plate 41 and is provided between the first rotating disk 23 and the second rotating disk 341. A lever 38 for guiding the discharging of the bottle caps is provided on the bottom plate 3421 and the front end of the lever 38 is close to the second notch 342. A discharge channel is provided at the 12 o'clock position of the bottom plate and is close to the lever 38. The feeding port of the bottle cap conveyor (not shown) is provided at the 12 o'clock position of the bottom plate 3421. The nozzle 120 is provided at the 3 o'clock position of the bottom plate 21. The second guide block 272 is provided at the 6 o'clock position of the bottom plate. The second guide block is located below the top plate and is directly opposite to the bottom plate. The position below is roughly equivalent to the 6 o'clock area on the chassis. Its position is set according to the actual needs of the scraper guide distance. In this design, this corresponding position is the best position. After the material is added at the 12 o'clock feed port, it is cut at the 3 o'clock position, and then the colloid is immediately transferred to the bottle cap, that is, the 6 o'clock area. Of course, the second guide block is a strip structure, and its structure is in the form of a downward-extending mountain peak, which gradually guides the scraper to move downward, so the entire area may occupy the position from 5 o'clock to 7 o'clock on the chassis.
[0027] Preferably, the hopper 14 is provided with a draw hopper (not shown), the draw port being connected to a pneumatic draw pipe and an air outlet pipe 263. When in use, the pneumatic draw pipe is directly connected to the container containing the raw material colloid, and the raw material colloid is drawn into the draw port by a vacuum method. One pipe performs the suction action while the other pipe serves as the air outlet pipe 263, thereby automating the feeding operation and improving efficiency.
[0028] Preferably, the end of the scraper rod 261 near the nozzle 120 is a hollow cylinder, and the hollow cylinder is provided with a half-moon-shaped cutout 265 from top to bottom along the forward direction of the first rotating drum 22. The end of the scraper rod 261 with the cutout 265 is very similar to a shovel-like structure with both sides tilted inward. The half-enclosed end of the scraper rod 261 can be more convenient when scraping the colloid, and can prevent the colloid from escaping, and can also allow it to fall along the inner wall to ensure that it falls into the bottle cap.
[0029] Preferably, the valve is a ball valve. Of course, it is not limited to the structure of the ball valve type, and the valve structure can be adjusted according to the actual structure, as long as the use of the valve can change direction well.
[0030] Preferably, the rocker includes a connecting rod 1231 connected to the valve in a transverse direction and a hand lever 1232 perpendicular to the connecting rod 1231. The direction of the valve can be easily changed by bending the hand lever 1232 through the lever principle.
[0031] Preferably, the heating plate 13 is a clamp-type structure clamped on the outer wall of the barrel 12, and the heating plate 13 is an electric heating plate. The clamp-type structure allows the heating plate 13 to heat the heating surface of the barrel 12. In this design, the heating plates 13 are provided in several groups and are evenly clamped on the outer wall of the barrel 12, ensuring uniform heating and rapid completion of the melting process.
[0032] Preferably, each of the pressing rods 37 is connected to the second drum 32 via a cam 333. The cam 333 is similar in principle and structure to the aforementioned guide groove (not shown) and cam 333, and will not be described in detail herein.
[0033] The bottle cap glue dispensing machine provided by the present invention first draws the raw material colloid into the hopper 14 through the extraction hopper (not shown), and then conveys the raw material colloid into the screw (not shown) through the hopper 14. The screw (not shown) is driven by the motor to rotate and push the raw material colloid forward. In this process, the heating plate 13 heats the barrel 12 so that its internal temperature rises and melts the raw material colloid. The heating plate 13 is an electric heating plate, so its temperature can also be adjusted through different gears. Since the effect of the small section of the newly melted colloid may not be good, This rotary valve hand lever 1232 is hit in the direction of the pre-extrusion port, so that the melted colloid is first discharged through the pre-extrusion port to observe its shape until it reaches a suitable state, and then the rotary valve hand lever 1232 is rotated to turn it to a position connected to the discharge port. At this time, the melted colloid will be squeezed out through the discharge port. The discharge port is set on the upper surface of the nozzle 120 to cooperate with the function of the scraper rod 261. After the scraper rod 261 moves downward from top to bottom and contacts the upper surface of the nozzle 120, it no longer moves downward, and as it rotates forward, the colloid can be directly scraped off. At the same time, the bottle cap conveyor feeds the cap into the chassis 21 and locks it into the first recess 24. The first rotating disk 23 drives the bottle cap to rotate. The nozzle 120 is arranged above the first rotating disk 23 and is higher than the height of the bottle cap feeding port (not shown). When the bottle cap passes under the nozzle 120, the top of the scraper rod 261 above is resisted by the downward force of the first guide block 271 and moves downward to contact the nozzle 120. The scraper rod 261 is also driven forward by the rotation force of the first rotating drum 22. The scraper rod 261 scrapes the colloid from the discharge port and pushes it to fall from the nozzle 120 into the bottle cap. At this time, the air pipe 263 connected to the scraper rod 261 will also assist the colloid to fall into the bottle cap better through instantaneous blowing; then the bottle cap quickly transitions to the bottom plate 34 of the die discharging device 3 through the transition disk 4. Selecting the shortest path transition can ensure Before the colloid hardens, it is flattened and spread completely. The second notch 342 of the second rotating disk 341 locks the bottle cap and drives it forward. At this time, the ejector rod 331 moves upward, and the pressure rod 37 moves downward simultaneously. This simultaneous movement shortens the overall time of pressing the colloid. The die 371 presses the colloid. Under pressure, the colloid is evenly spread and seamlessly combined with the bottle cap. The pattern on the die 371 corresponds to the pattern on the bottom of the bottle cap, so different die 371s can be used for different bottle caps. After assembly, the die 371 continues to press for a while to ensure that the colloid cools and takes shape. After shaping, the bottle cap is also brought to the discharge channel 39. At this time, the pressure rod 37 moves upward, and the ejector rod 331 moves downward and retreats to the same plane as the bottom plate 34. The bottle cap is then pushed out of the second rotating disk 341 by the push rod 38 and discharged from the discharge channel 39. Under normal circumstances, the discharged bottle caps will also be tested by a detection mechanism for the combination of the colloid and the bottle cap, and unqualified ones will be rejected.
[0034] The bottle cap-specific glue dispensing machine provided by the present invention effectively solves the problem of using colloid as a sealing structure in the bottle cap. The process of loading, melting, cutting, transporting and pressing the colloid is completed by combining several groups of structures with different purposes. It can reduce costs and, due to its own properties and characteristics, it can better serve as a sealing member and provide better sealing performance.
[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
