The operator manually squeezes the neck of the screw into the central hole of the insulating granule so that the end of the screw fits with the insulating granule, thereby realizing the screw sleeve granule process.

[0004] The above method of manually squeezing the screw into the insulating granule by the operator to realize the screw sleeve granule has high labor cost, is time-consuming and laborious, and at the same time results in low production efficiency. Summary of the Invention

[0005] In order to help solve the problem that the method of manually squeezing the screw into the insulating granule to realize the screw sleeve granule is time-consuming and laborious and results in low production efficiency, a screw sleeve granule system provided by this application adopts the following technical solutions: It includes a base, and a feeding device for conveying screws and insulating granule feeding is provided on the base. A sleeve granule device is provided at the output end of the feeding device. The sleeve granule device includes a material tray rotatably connected to the base. The material tray is arranged at the discharge end of the feeding device. The screws and insulating granules conveyed from the feeding device are placed on the material tray. A number of limiting units for simultaneously limiting the screws and insulating granules are provided on the material tray. The sleeve granule device further includes an extrusion unit for squeezing the screws in the limiting unit into the insulating granules. A driving unit for driving the material tray to rotate is provided on the base.

[0006] Through the above technical solutions, when the screw sleeve granule operation needs to be carried out, the screws and insulating granules are respectively conveyed to the material tray along the feeding device. The limiting unit is used to simultaneously limit the screws and insulating granules, reducing the possibility of the screws and insulating granules shifting. The extrusion unit is started to squeeze the screws in the limiting unit into the insulating granules, thereby realizing the screw sleeve granule. By using the feeding device and the sleeve granule device, the labor cost is reduced, it is time-saving and laborious, and at the same time the sleeve granule speed is increased, thereby improving the production efficiency.

[0007] In a specific feasible implementation, the feeding device includes a screw feeding unit for conveying screws and an insulating granule feeding unit for conveying insulating granules. The screw feeding unit includes a vibrating disk arranged on a base. The output end of the vibrating disk is provided with a screw feeding track. The material tray is located at the output end of the screw feeding track. A number of screws are sequentially arranged in the screw feeding track. The base is provided with a pushing assembly for pushing the screws at the output end of the screw feeding unit to the material tray and a blocking assembly for controlling the opening and closing of the screw feeding track.

[0008] Through the above technical solution, when the vibrating disk is started, the vibrating disk conveys the screws in sequence and neatly to the screw feeding track. By using the pushing assembly and the blocking assembly, the screws are sequentially conveyed from the screw feeding track to the material tray, improving the conveying efficiency of screw feeding and reducing the possibility of screw jamming in the screw feeding track caused by simultaneously conveying multiple screws.

[0009] In a specific feasible implementation, the pushing assembly includes a mounting seat arranged on the base. Two limiting blocks are provided on the mounting seat. A guiding track is arranged between the two limiting blocks. The guiding track communicates with the screw feeding track. A pushing cylinder is provided on the mounting seat. The output end of the pushing cylinder is provided with a push rod. The push rod corresponds to the guiding track. The guiding track corresponds to the limiting unit on the material tray.

[0010] Through the above technical solution, when the pushing cylinder is started, the push rod at the output end of the pushing cylinder is driven to extend. The guiding track plays a role in limiting the movement direction of the push rod, enabling the push rod to slide along the guiding track to push the screw to the limiting unit on the material tray, improving the conveying efficiency of screw feeding.

[0012] Through the above technical solution, when the push rod extends under the drive of the pushing cylinder, the push rod pushes the screw located between the guiding track and the screw feeding track. The screw drives the flap to rotate by squeezing the flap under the drive of the push rod, making the screw feeding track in an open state. The push rod slides along the guiding track to push the screw to the limiting unit on the material tray. Subsequently, when the push rod retracts under the drive of the pushing cylinder, the flap resets under the action of the elastic member, making the screw feeding track in a closed state.

A clamping block is arranged in the mounting groove. A limiting hole is formed in the clamping block. The limiting hole is coaxially arranged with the limiting groove. The screws output from the screw feeding unit are sequentially placed in the limiting holes of the limiting units.

[0014] Through the above technical solution, the limiting groove positions the insulating particles, and the limiting hole positions the screws, reducing the possibility of the screws and insulating particles shifting, improving the stability of the placement of the screws and insulating particles. Since the limiting groove and the limiting hole are coaxially arranged, the screw can accurately pass through the insulating particle, improving the accuracy of the screw sleeving the particle.

[0015] In a specific feasible implementation, a cover plate is provided on the tray, and the clamping block is located between the cover plate and the bottom of the mounting groove.

[0016] Through the above technical solution, the cover plate reduces the interference of external equipment on the clamping block and reduces the possibility of debris, dust, etc. entering the mounting groove, playing a protective role.

The pressing column is coaxially arranged with the limiting hole of the limiting unit, and the screw is located between the pressing column and the insulating particle.

[0018] Through the above technical solution, start the pressing cylinder to drive the pressing column at the output end of the pressing cylinder to press down, and press the screw in the limiting hole into the insulating particle, completing the processing step of the screw sleeving the particle, reducing the manual process of manually pressing the screw to sleeve the particle, reducing the labor cost, saving time and effort while improving the production efficiency.

[0019] In a specific feasible implementation, the clamping block includes a first clamping block and a second clamping block respectively rotatably connected to the tray. A first arc-shaped groove is formed on the surface of the first clamping block facing the second clamping block. A second arc-shaped groove is formed on the surface of the second clamping block facing the first clamping block. The first arc-shaped groove and the second arc-shaped groove are spliced to form the limiting hole. A first top groove is formed on the surface of the first clamping block facing the second clamping block. A second top groove is formed on the surface of the second clamping block facing the first clamping block. The first top groove and the second top groove are spliced to form a top hole. A telescopic cylinder is provided on the base. The output end of the telescopic cylinder is provided with a conical top rod matching the top hole. The conical top rod passes through the tray and is inserted into the top hole. A reset assembly for driving the first clamping block and the second clamping block to reset is provided on the tray.

[0020] Through the above technical solution, the telescopic cylinder is started, and the conical top rod at the output end of the telescopic cylinder is extended and inserted into the top hole, thereby driving the first clamping block and the second clamping block to open, and the first clamping block and the second clamping block release the restriction on the screw completed by the sleeve grain, realizing the automatic feeding of the screw completed by the sleeve grain; the conical top rod retracts under the drive of the telescopic cylinder, and the first clamping block and the second clamping block are reset under the action of the reset assembly, thereby driving the first clamping block and the second clamping block to close.

[0021] In a specific feasible embodiment, the reset assembly includes a first spring and a second spring. The first clamping block and the second clamping block are located between the first spring and the second spring. Two ends of the first spring are respectively connected to the groove wall of the installation groove and the first clamping block, and two ends of the second spring are respectively connected to the groove wall of the installation groove and the second clamping block.

[0022] Through the above technical solution, when the conical top rod extends and is inserted into the top hole under the drive of the telescopic cylinder, the first spring is pressed tightly between the first clamping block and the groove wall of the installation groove, and the second spring is pressed tightly between the second clamping block and the groove wall of the installation groove.

Detailed implementation manners

[0031] The following further elaborates on this application in conjunction with the attached Figures 1-4 for a more detailed description of this application.

[0032] The embodiments of this application disclose a screw sleeve granule system.

[0033] Referring to Figure 1 and Figure 2 , the screw sleeve granule system includes an inclined base 1. A feeding device for conveying screws and feeding insulating granules is arranged on the base 1. A sleeve granule device 3 is arranged at the output end of the feeding device. A material receiving pipe 2 is installed on the base 1, and the pipe orifice of the material receiving pipe 2 is arranged at the discharging end of the sleeve granule device 3. A material receiving bucket for receiving the screws after sleeve granulation can be arranged at the output end of the material receiving pipe 2. The screws after sleeve granulation fall into the material receiving bucket after being collected by the material receiving pipe 2, thus facilitating the centralized storage of the screws after sleeve granulation. In the embodiments of this application, the base 1 is inclined. On the one hand, it facilitates the conveyance of screws and insulating granules from the feeding device to the sleeve granule device 3, improving the feeding efficiency of screws and insulating granules. On the other hand, it facilitates the fallen screws after sleeve granulation to fall into the material receiving pipe 2 under the action of gravity, improving the discharging efficiency of the sleeve granule device 3.

[0034] Referring to Figure 1 and Figure 2, the sleeving device 3 includes a circular material tray 4 rotatably connected to the base 1. The material tray 4 is arranged at the discharge end of the feeding device. The screws and insulating grains conveyed from the feeding device are placed on the material tray 4. A driving unit 7 for driving the rotation of the material tray 4 is arranged on the base 1. In the embodiment of the present application, the driving unit 7 can be set as a driving motor. The material tray 4 is arranged at the output end of the driving motor. Starting the driving motor drives the rotation of the material tray 4 at the output end of the driving motor. A plurality of limiting units 5 for simultaneously limiting the screws and insulating grains are arranged on the material tray 4. The sleeving device 3 further includes an extrusion unit 6 for extruding the screws in the limiting unit 5 into the insulating grains.

[0035] Therefore, when sleeving the screws is required, the screws and insulating grains are respectively conveyed to the material tray 4 along the feeding device. The limiting unit 5 is used to limit the screws and insulating grains simultaneously, reducing the possibility of the screws and insulating grains shifting. Starting the extrusion unit 6, the screws in the limiting unit 5 are extruded into the insulating grains, thus realizing the sleeving of the screws. By using the feeding device and the sleeving device 3, the labor cost is reduced, and the sleeving speed is increased while saving time and effort, thereby improving the production efficiency.

[0036] Refer to Figure 1 and Figure 2 , the feeding device includes a screw feeding unit 8 for conveying screws and an insulating grain feeding unit 9 for conveying insulating grains. The screw feeding unit 8 includes a vibrating disk 10 arranged on the base 1. The output end of the vibrating disk 10 is connected to a screw feeding track 11. The material tray 4 is located at the output end of the screw feeding track 11. A plurality of screws are successively placed in the screw feeding track 11. In the embodiment of the present application, the structure of the insulating grain feeding unit 9 is the same as that of the screw feeding unit 8. A pushing component for pushing the screws at the output end of the screw feeding unit 8 to the material tray 4 and a blocking component for controlling the opening and closing of the screw feeding track 11 are arranged on the base 1.

[0037] Therefore, by respectively starting the vibrating disks 10 corresponding to the screws and insulating grains, the vibrating disk 10 corresponding to the screw feeding arranges the screws neatly and conveys them to the screw feeding track 11 in sequence. The vibrating disk 10 corresponding to the insulating grain feeding arranges the insulating grains neatly and conveys them to the insulating grain feeding track 39 in sequence. The insulating grains in the insulating grain feeding track 39 automatically slide into the corresponding limiting units 5 on the material tray 4 in sequence. By using the pushing component and the blocking component, the screws are successively conveyed from the screw feeding track 11 to the corresponding limiting units 5 on the material tray 4, improving the conveying efficiency of the screw feeding and reducing the possibility of multiple screws being blocked in the screw feeding track 11 during simultaneous conveyance.

[0038] Refer to Figure 2 and Figure 3, the pushing component includes a mounting seat 12 bolted to the base 1. Two limit blocks 13 are fixedly connected to the mounting seat 12. A guiding track 14 is arranged between the two limit blocks 13. The guiding track 14 communicates with the screw feeding track 11. A pushing cylinder 15 is bolted to the mounting seat 12. A push rod 16 is installed at the output end of the pushing cylinder 15. The push rod 16 corresponds to the guiding track 14, and the guiding track 14 corresponds to the limiting unit 5 on the tray 4.

[0039] Therefore, when the pushing cylinder 15 is started, the push rod 16 at the output end of the pushing cylinder 15 extends. The guiding track 14 plays a role in limiting the movement direction of the push rod 16, so that the push rod 16 slides along the guiding track 14 to push the screw onto the limiting unit 5 on the tray 4, improving the conveying efficiency of screw feeding.

[0040] Refer to Figure 2 and Figure 3 , the blocking component includes a flap 17 rotatably connected to the mounting seat 12. An elastic seat 18 is fixedly connected to the mounting seat 12. The flap 17 is located between the elastic seat 18 and the output end of the screw feeding track 11. An elastic member is arranged between the elastic seat 18 and the flap 17. The screw is located between the push rod 16 and the flap 17. In the embodiment of the present application, the elastic member can adopt a torsion spring. The torsion spring is sleeved on the outer edge of the shaft of the flap 17. One end of the torsion spring is connected to the flap 17, and the other end is connected to the elastic seat 18.

[0041] Therefore, when the push rod 16 extends under the drive of the pushing cylinder 15, the push rod 16 pushes the screw located between the guiding track 14 and the screw feeding track 11. The screw squeezes the flap 17 under the drive of the push rod 16 to drive the flap 17 to rotate, so that the screw feeding track 11 is in an open state. The push rod 16 slides along the guiding track 14 to push the screw onto the limiting unit 5 on the tray 4. Subsequently, the push rod 16 retracts under the drive of the pushing cylinder 15, and the flap 17 resets under the action of the elastic member, so that the screw feeding track 11 is in a closed state.

[0042] Refer to Figure 2 and Figure 3, in the embodiment of the present application, the number of the limiting units 5 on the tray 4 is set to 8, and the 8 limiting units 5 are arranged in a circumferential array on the tray 4. The limiting unit 5 includes a mounting groove 19 opened on the surface of the tray 4 facing away from the base 1. A limiting groove 20 matching the size of the insulating particles is opened at the bottom of the mounting groove 19. The limiting groove 20 is correspondingly arranged with the output end of the insulating particle feeding unit 9. The insulating particles output from the insulating particle feeding unit 9 are sequentially placed in the limiting grooves 20 of several limiting units 5. A clamping block 21 is arranged in the mounting groove 19. A limiting hole 22 is opened on the clamping block 21. The limiting hole 22 is coaxially arranged with the limiting groove 20. The screws output from the screw feeding unit 8 are sequentially placed in the limiting holes 22 of the limiting units 5. A rectangular cover plate 23 is bolted on the tray 4. The clamping block 21 is located between the cover plate 23 and the bottom of the mounting groove 19. The cover plate 23 reduces the interference of external equipment on the clamping block 21 and reduces the possibility of debris, dust, etc. entering the mounting groove 19, playing a protective role.

[0043] Therefore, the limiting groove 20 plays a role in limiting the position of the insulating particles, and the limiting hole 22 plays a role in limiting the position of the screws, reducing the possibility of the screws and the insulating particles shifting, improving the stability of the placement of the screws and the insulating particles. Since the limiting groove 20 and the limiting hole 22 are coaxially arranged, the screws can accurately pass through the insulating particles, improving the accuracy of the screw sleeve particles.

[0044] Refer to Figure 2 and Figure 3 , the pressing unit 6 includes a pressing seat 24 arranged on the base 1. A pressing cylinder 25 is arranged on the pressing seat 24. The output end of the pressing cylinder 25 is provided with a pressing column 26. The pressing column 26 is coaxially arranged with the limiting hole 22 of the limiting unit 5 and the screw is located between the pressing column 26 and the insulating particles.

[0045] Therefore, when the pressing cylinder 25 is started, the pressing column 26 at the output end of the pressing cylinder 25 is driven to press down, and the screw in the limiting hole 22 is pressed into the insulating particles, completing the processing step of the screw sleeve particles, reducing the manual operation process of manually pressing the screw sleeve particles, reducing the labor cost, saving time and effort, and improving the production efficiency at the same time.

[0046] Refer to Figure 2 and Figure 4, the clamping block 21 includes a first clamping block 27 and a second clamping block 28 which are respectively rotatably connected to the material tray 4. In the embodiment of the present application, the first clamping block 27 and the second clamping block 28 have the same shape. A first arc-shaped groove 29 is formed on the surface of the first clamping block 27 facing the second clamping block 28, and a second arc-shaped groove 30 is formed on the surface of the second clamping block 28 facing the first clamping block 27. The first arc-shaped groove 29 and the second arc-shaped groove 30 have the same size. The first arc-shaped groove 29 and the second arc-shaped groove 30 are spliced to form a limiting hole 22. A first top groove 34 is formed on the surface of the first clamping block 27 facing the second clamping block 28, and a second top groove 35 is formed on the surface of the second clamping block 28 facing the first clamping block 27. Both the first top groove 34 and the second top groove 35 are semi-circular and have the same size. The first top groove 34 and the second top groove 35 are spliced to form a top hole 33. A telescopic cylinder 37 is installed on the base 1, and the output end of the telescopic cylinder 37 is connected with a conical top rod 36 which is matched with the top hole 33. The conical top rod 36 passes through the material tray 4 and is inserted into the top hole 33. A reset assembly for driving the first clamping block 27 and the second clamping block 28 to reset is provided on the material tray 4.

[0047] Therefore, when the telescopic cylinder 37 is started, the conical top rod 36 at the output end of the telescopic cylinder 37 is driven to extend and inserted into the top hole 33, thereby driving the first clamping block 27 and the second clamping block 28 to open, and the first clamping block 27 and the second clamping block 28 loosen the restriction on the screw with the sleeve completed, realizing the automatic feeding of the screw with the sleeve completed; the conical top rod 36 retracts under the drive of the telescopic cylinder 37, and the first clamping block 27 and the second clamping block 28 reset under the action of the reset assembly, thereby driving the first clamping block 27 and the second clamping block 28 to close.

[0048] Referring to Figure 2 and Figure 4 , the reset assembly includes a first spring 31 and a second spring 32. The first clamping block 27 and the second clamping block 28 are located between the first spring 31 and the second spring 32. Two ends of the first spring 31 are respectively connected to the groove wall of the installation groove 19 and the first clamping block 27, and two ends of the second spring 32 are respectively connected to the groove wall of the installation groove 19 and the second clamping block 28.

[0049] Therefore, when the conical top rod 36 is driven by the telescopic cylinder 37 to extend and inserted into the top hole 33, the first spring 31 is pressed tightly between the first clamping block 27 and the groove wall of the installation groove 19, and the second spring 32 is pressed tightly between the second clamping block 28 and the groove wall of the installation groove 19. At this time, the first clamping block 27 and the second clamping block 28 are separated from each other, that is, in the open state of the clamping block 21, which is convenient for the feeding of the screw with the sleeve completed; when the conical top rod 36 retracts under the drive of the telescopic cylinder 37, the first clamping block 27 resets under the action of the first spring 31, and the second clamping block 28 resets under the action of the second spring 32. At this time, the first clamping block 27 and the second clamping block 28 are closed to each other, that is, the clamping block 21 is in the closed state.

[0050] The implementation principle of the embodiment of this application is as follows: When the operation of sleeving grains on the screw is required, the vibrating trays 10 corresponding to the screw and the insulating grains are started respectively. The vibrating tray 10 corresponding to the screw feeding arranges the screws neatly in sequence and conveys them to the screw feeding track 11. The vibrating tray 10 corresponding to the insulating grain feeding arranges the insulating grains neatly in sequence and conveys them to the insulating grain feeding track 39. The insulating grains in the insulating grain feeding track 39 automatically slide into the corresponding limiting grooves 20 on the tray 4 in sequence. The screws in the screw feeding track 11 automatically slide to the output end of the screw feeding track 11. At this time, the screw is located between the guiding track 14 and the output end of the screw feeding track 11 and is blocked by the paddle 17, and the screw feeding track 11 is in a closed state; the driving unit 7 is started to drive the tray 4 to rotate, and the limiting unit 5 corresponding to the insulating grain feeding track 39 is rotated to the output end of the screw feeding track 11;

[0051] The pushing cylinder 15 is started to drive the push rod 16 at the output end of the pushing cylinder 15 to extend. The push rod 16 pushes the screw, and the screw drives the paddle 17 to rotate by pressing the paddle 17 under the drive of the push rod 16, so that the screw feeding track 11 is in an open state. The push rod 16 continues to slide along the guiding track 14 to push the screw into the limiting hole 22 on the tray 4. At this time, the screw is located directly above the insulating grain and the two are coaxially arranged. Subsequently, the push rod 16 retracts under the drive of the pushing cylinder 15, and the paddle 17 resets under the action of the elastic member, so that the screw feeding track 11 resets to a closed state; the driving unit 7 is started to drive the tray 4 to rotate, and the limiting unit 5 corresponding to the screw feeding track 11 is rotated to directly below the pressing unit 6;

[0052] The pressing cylinder 25 is started to drive the pressing column 26 at the output end of the pressing cylinder 25 to press down, and the screw in the limiting hole 22 is pressed into the insulating grain to complete the processing step of sleeving the screw with grains; the driving unit 7 is started to drive the tray 4 to rotate, and the limiting unit 5 corresponding to the pressing unit 6 is rotated to a position corresponding to the receiving pipe 2;

[0053] Start the telescopic cylinder 37 to drive the conical top rod 36 at the output end of the telescopic cylinder 37 to extend and plug into the top hole 33. The first spring 31 is pressed tightly between the first clamping block 27 and the groove wall of the installation groove 19, and the second spring 32 is pressed tightly between the second clamping block 28 and the groove wall of the installation groove 19. At this time, the first clamping block 27 and the second clamping block 28 are separated from each other, that is, the clamping block 21 is in the open state, which is convenient for the feeding of the sleeved screws. When starting the telescopic cylinder 37 and the conical top rod 36 retracts under the drive of the telescopic cylinder 37, the first clamping block 27 is reset under the action of the first spring 31, and the second clamping block 28 is reset under the action of the second spring 32. At this time, the first clamping block 27 and the second clamping block 28 are closed to each other, that is, the clamping block 21 is in the closed state, and the sleeved screws fall into the receiving pipe 2 for collection. By using the feeding device and the sleeving device 3, the labor cost is reduced, the sleeving speed is increased while saving time and effort, thereby improving the production efficiency.
