Description

Technical Field

[0001] The present application relates to the field of nut forming equipment, and in particular to a material receiving mechanism of a four-claw nut forming machine. Background Art

[0002] Four-claw nut is a kind of furniture nut which is more firm than the general wood board inlaid nut. Its four claws are symmetrically distributed, and the claw nails can effectively buckle the wood board. Four-claw nut is widely used in furniture installation such as sofas, beds, cabinets, desks and other wooden household items. Usually, the nuts of household items will rotate due to various reasons during installation, resulting in installation difficulties. The four-claw nut is embedded in the wood board through the claw nails, and then the screws are screwed into the wood board to reduce the defect of ordinary nuts rotating.

[0003] At present, factories usually use four-claw nut stamping and forming machines to process four-claw nuts. The nuts to be stamped will be fed into the feed port of the four-claw nut forming machine in sequence through the vibrating plate. After the nuts are stamped by the four-claw nut forming machine, claw nails can be stamped out on the nuts. The four-claw nut after stamping will eventually be sent out from the discharge port of the forming machine under the push of the pushing mechanism, thus completing the entire stamping work.

[0004] Regarding the processing process of the above-mentioned four-claw nuts, the inventor found that after the stamped four-claw nuts are sent out from the discharge port of the forming machine, the four-claw nuts will fall into the storage bucket placed in advance by the workers at the discharge port under the action of their own gravity. As the number of four-claw nuts in the storage bucket continues to increase, the pressure on the four-claw nuts near the bottom of the storage bucket will gradually increase. Workers usually only empty the four-claw nuts in the storage bucket when the four-claw nuts in the storage bucket are full. This will cause the claws of the four-claw nuts near the bottom of the storage bucket to be subjected to greater pressure, resulting in extrusion, bending and deformation, which will eventually affect the normal use of the four-claw nuts. Summary of the invention

[0005] When collecting the four-claw nuts, in order to reduce the possibility of the claws of the four-claw nuts near the bottom being easily squeezed and bent, the present application provides a collecting mechanism for a four-claw nut forming machine.

[0006] The present application provides a material receiving mechanism of a four-claw nut forming machine, which adopts the following technical solution:

[0007] A material receiving mechanism of a four-claw nut forming machine includes a material receiving box, the material receiving box is provided with a feed opening for four-claw nuts to fall into, the material receiving box is provided with a partition, the partition separates the interior of the material receiving box into a feed chamber and a storage chamber, the feed opening is connected to the feed chamber; a first material receiving plate is slidably arranged in the material receiving box, the material receiving box is provided with a driving component for driving the first material receiving plate to slide between the feed chamber and the storage chamber, the material receiving box is provided with an input end for real-time collection of the weight value of the four-claw nuts on the first material receiving plate, the gravity sensing control module is provided with a gravity preset value, the gravity sensing control module is connected with a driving source signal on the driving component, when the weight value collected by the gravity sensing control module exceeds the gravity preset value, the gravity sensing control module outputs a first control signal to control the driving component to move the first material receiving plate into the storage chamber; a second material receiving plate located below the first material receiving plate is also provided in the material receiving box.

[0008] By adopting the above technical scheme, when the first receiving plate is completely moved into the feed chamber under the drive of the driving component, the four-claw nuts that have been processed and formed can fall smoothly onto the first receiving plate through the feed port; then the gravity sensing control module is used to collect and monitor the weight value of the four-claw nuts on the first receiving plate in real time. When the weight value collected by the gravity sensing control module exceeds the preset gravity value, the output end of the gravity sensing control module will output a first control signal to control the driving component to move the first receiving plate into the storage chamber. At this time, the first receiving plate stops receiving the four-claw nuts, thereby effectively reducing the probability of the four-claw nuts near the bottom being squeezed and bent due to greater pressure; and the rear four-claw nuts will fall onto the second receiving plate located below the first receiving plate, and the four-claw nuts will continue to be collected by the second receiving plate, so that the four-claw nut forming machine does not need to be shut down, thereby ensuring processing efficiency.

[0009] Optionally, a storage box for storing four-claw nuts is placed on the first receiving plate, and the gravity sensing control module includes a pressure sensor for collecting the total weight of the storage box, and the pressure sensor is arranged below the storage box.

[0010] By adopting the above technical solution, when the storage box containing the four-claw nuts is moved into the material storage chamber along with the first material receiving plate, the storage box is convenient for the staff to take out the four-claw nuts on the first material receiving plate together, and it is also convenient for the staff to uniformly pack the four-claw nuts in the storage box.

[0011] Optionally, an oil storage chamber for storing lubricating oil is formed on the inner wall of the bottom of the material receiving box, and the oil storage chamber connects the feed chamber with the storage chamber; an oil pump is arranged in the oil storage chamber, and the output end of the oil pump is connected to an oil pipe for oiling the four-claw nut forming machine.

[0012] By adopting the above technical scheme, when the four-claw nut forming machine is stamping the workpiece, the oil pump is started to pump the lubricating oil in the oil storage chamber into the four-claw nut forming machine through the oil pipe. By oiling the four-claw nut forming machine, lubrication of the workpiece to be stamped can be achieved. Finally, the excess lubricating oil will flow back from the discharge port of the four-claw nut forming machine into the oil storage chamber, thereby realizing the recycling of the lubricating oil.

[0013] Optionally, the storage box and the first material receiving plate are both provided with oil drain holes.

[0014] By adopting the above technical solution, on the one hand, it is ensured that the lubricating oil on the four-claw nut in the storage box can flow back to the oil storage chamber smoothly, thereby degreasing the four-claw nut; on the other hand, by degreasing the four-claw nut, the accuracy of the pressure sensor detection value can be ensured.

[0015] Optionally, the driving assembly includes a first screw rod rotatably arranged in a material receiving box, and the length direction of the first screw rod is arranged along the sliding direction of the first material receiving plate; the first screw rod is passed through the first material receiving plate, and the first screw rod is threadedly connected to the first material receiving plate; the driving source on the driving assembly is used to drive the first screw rod to rotate.

[0016] By adopting the above technical solution, when the first screw rod rotates under the drive of the driving source, the first screw rod can drive the first material receiving plate to slide along the length direction of the first screw rod; when the sliding direction of the first material receiving plate needs to be changed, the sliding direction of the first material receiving plate can be changed by simply changing the rotation direction of the first screw rod, and the operation is simple and quick.

[0017] Optionally, the driving assembly also includes a second screw rod parallel to the first screw rod, and the second screw rod is rotatably arranged in a material receiving box; the second material receiving plate is slidably arranged in the material receiving box along the length direction of the second screw rod, and the second screw rod is threadedly connected to the second material receiving plate; the other input end of the gravity sensing control module is used to collect the weight value of the four-claw nut on the second material receiving plate; when the gravity sensing control module collects that the weight value of the four-claw nut on the second material receiving plate exceeds the preset gravity value, the output end of the gravity sensing control module outputs a second control signal to control the driving source on the driving assembly for driving the second screw rod to rotate, and controls the second screw rod to move the second material receiving plate into the material storage chamber.

[0018] By adopting the above technical solution, when the gravity sensing control module detects that the weight of the four-claw nut on the second receiving plate exceeds the preset gravity value, the gravity sensing control module will control the rotation of the second screw rod to move the first receiving plate into the storage chamber, thereby effectively reducing the probability of the four-claw nut near the bottom of the second receiving plate being squeezed and bent due to greater pressure; after the four-claw nut on the second receiving plate is moved into the storage chamber, the first receiving plate in an idle state is moved back into the feeding chamber by controlling the rotation of the first screw rod, so that the collection of the four-claw nuts can continue.

[0019] Optionally, transmission gears are sleeved on the central axes of the first screw rod and the second screw rod, and adjacent transmission gears are meshed with each other; the first material receiving plate and the second material receiving plate maintain synchronous sliding and the sliding directions are opposite; the first screw rod and the second screw rod share the same driving source.

[0020] By adopting the above technical scheme, under the transmission action of the transmission gear, the purpose of controlling the first receiving plate and the second receiving plate to maintain synchronous sliding is achieved through the same driving source; and when the first receiving plate and the second receiving plate are performing synchronous sliding, the automatic switching of the receiving work is realized, the idle time of the feed chamber is shortened, and the smooth collection of the four-claw nut by the feed chamber is ensured, and the structural design is ingenious.

[0022] By adopting the above technical scheme, when the first material receiving plate and the second material receiving plate are in a sliding state, in order to prevent the four-claw nut from accidentally falling into the oil storage chamber below, the two sets of control switches will be in an untriggered state at this time, and the motor drive will control the baffle plate to rotate to a closed state. At this time, the four-claw nut will not be able to fall into the feed chamber from the feed port, and the four-claw nut sent out from the discharge port of the molding machine will be temporarily blocked on one side of the baffle plate; when any set of control switches is triggered by being pressed by the first material receiving plate or the second material receiving plate, it means that the first material receiving plate or the second material receiving plate has been moved to the designated position of the feed chamber, and the four-claw nut can be collected; at this time, the control switch will control the motor drive to rotate the baffle plate to an open state, and the four-claw nut can continue to collect.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The present application embodiment discloses a material receiving mechanism of a four-claw nut forming machine. Figure 1 , Figure 2 The receiving mechanism of the four-claw nut forming machine includes a receiving box 1. A feed port 10 for four-claw nuts to fall into is provided on the top of the receiving box 1. A partition 11 arranged along the height direction of the receiving box 1 is fixedly installed on the inner wall of the receiving box 1. The partition 11 separates the internal space of the receiving box 1 into a feed chamber 12 and a storage chamber 13. The feed port 10 is located above the feed chamber 12 and communicates with the inside of the feed chamber 12. A first receiving plate 121 and a second receiving plate 14 are slidably arranged in parallel with each other in the receiving box 1. The first receiving plate 121 is located above the second receiving plate 14, and both the first receiving plate 121 and the second receiving plate 14 slide along the length direction of the receiving box 1. A clearance hole 110 is penetrated on the partition 11 for the first receiving plate 121 and the second receiving plate 14 to pass through respectively.

[0034] like Figure 2 , Figure 3As shown, a driving assembly 2 for driving the first receiving plate 121 and the second receiving plate 14 to slide between the feed chamber 12 and the storage chamber 13 is provided on the receiving box 1. The driving assembly 2 includes a first screw rod 21 rotatably arranged inside the receiving box 1, and the length direction of the first screw rod 21 is arranged along the sliding direction of the first receiving plate 121. The first screw rod 21 passes through the first receiving plate 121 and is threadedly connected with the first receiving plate 121. The driving assembly 2 also includes a servo motor 20 fixedly mounted on the outer wall of the receiving box 1, and the output shaft of the servo motor 20 is fixedly connected to the first screw rod 21 through a coupling. By starting the servo motor 20 to drive the first screw rod 21 to rotate, the first receiving plate 121 can slide between the feed chamber 12 and the storage chamber 13 under the drive of the first screw rod 21, and the sliding direction of the first receiving plate 121 can be changed by controlling the forward and reverse rotation of the servo motor 20. When the first receiving plate 121 moves into the feeding cavity 12 , the four-claw nut delivered from the discharge port of the molding machine can fall onto the first receiving plate 121 through the feeding port 10 .

[0035] like Figure 2 , Figure 3As shown, a storage box 122 for storing four-claw nuts is placed on the first receiving plate 121, and the opening of the storage box 122 faces upward. A gravity sensing control module 3 is installed on the receiving box 1. The gravity sensing control module 3 may include a central processing unit such as a CPU or an MPU, or a host system built with the CPU or the MPU as the core, including hardware and software. People can freely control the gravity sensing control module 3 by programming so that it runs according to people's wishes. The hardware part of controlling the gravity sensing control module 3 includes a pressure sensor 31, which is installed on the first receiving plate 121 and is located below the storage box 122. The output end of the gravity sensing control module 3 realizes signal communication with the servo motor 20, and the input end of the pressure sensor 31 is used to collect the weight value of the four-claw nut in the storage box 122 in real time. The gravity sensing control module 3 is provided with a preset gravity value set manually. When the first material receiving plate 121 is located in the feeding chamber 12 and the gravity sensing control module 3 detects that the weight value collected by the pressure sensor 31 exceeds the preset gravity value, the output end of the gravity sensing control module 3 will output a first control signal to control the servo motor 20 to drive the first screw rod 21 to rotate, so that the first screw rod 21 moves the first material receiving plate 121 from the feeding chamber 12 into the storage chamber 13. At this time, the staff can take out the storage box 122 moved into the storage chamber 13 together with the four-claw nut. It is mentioned that a self-locking unit is also provided in the gravity sensing control module 3, and signal transmission is realized between the self-locking unit and the pressure sensor 31. When the four-claw nut is moved into the storage chamber 13, the self-locking unit will send a self-locking signal to control the servo motor 20 to stop rotating and realize self-locking until the four-claw nut moved into the storage chamber 13 is taken out from the material receiving box 1. At this time, the self-locking unit detects that the weight value of the four-claw nut located in the storage chamber 13 is less than the preset value of gravity, and the self-locking unit will send an unlocking signal to realize the unlocking of the servo motor 20. At this time, the servo motor 20 can continue to perform subsequent actions.

[0036] like Figure 2 , Figure 3As shown, a large number of oil drain holes 123 are provided in the storage box 122 and the first receiving plate 121, and the driving assembly 2 also includes a second screw rod 22 rotatably arranged inside the receiving box 1, the second screw rod 22 is located below the first screw rod 21, and the first screw rod 21 and the second screw rod 22 are parallel to each other, and the length direction of the second screw rod 22 extends along the sliding direction of the second receiving plate 14. The second screw rod 22 is penetrated on the second receiving plate 14, and the second screw rod 22 is threadedly connected to the second receiving plate 14. When the second screw rod 22 rotates, the second screw rod 22 can drive the second receiving plate 14 to slide. The first screw rod 21 and the second screw rod 22 are each provided with a transmission gear 18 in a coaxial sleeve on their central axis, and adjacent transmission gears 18 are meshed with each other. Under the transmission of the transmission gear 18, the first screw rod 21 and the second screw rod 22 can share the same servo motor 20. When the servo motor 20 is working, the first receiving plate 121 and the second receiving plate 14 will keep sliding synchronously but in opposite directions. The specific working condition is: when the first receiving plate 121 is driven by the first screw rod 21 to move from the feeding chamber 12 to the storage chamber 13, during this process, the transmission gear 18 will control the second screw rod 22 to move the second receiving plate 14 located in the storage chamber 13 into the feeding chamber 12.

[0037] like Figure 2 , Figure 3 As shown, the gravity sensing control module 3 also includes another set of pressure sensors 31 arranged on the second receiving plate 14. A storage box 122 for storing four-claw nuts is also placed on the second receiving plate 14. The pressure sensor 31 is also arranged below the relative storage box 122, and the pressure sensor 31 on the second receiving plate 14 is also used to collect the total weight of the upper storage box 122 in real time. When the gravity sensing control module 3 collects the weight value of the four-claw nuts on the second receiving plate 14 that exceeds the preset gravity value, the output end of the gravity sensing control module 3 will output a second control signal to control the servo motor 20 to drive the second screw 22 to rotate, thereby realizing the second receiving plate 14 is moved into the storage chamber 13.

[0038] like Figure 2 , Figure 3 as well as Figure 4 As shown, a large number of oil drain holes 123 are also penetrated on the second receiving plate 14, and an oil storage cavity 15 for storing lubricating oil is formed on the inner side wall of the bottom of the receiving box 1, which is located below the second receiving plate 14. The oil storage cavity 15 connects the feed cavity 12 with the storage cavity 13, and an oil pump 16 is installed in the oil storage cavity 15. The output end of the oil pump 16 is connected to an oil pipe 161 for oiling the four-claw nut forming machine.

[0039] like Figure 3 , Figure 4As shown, a guide plate 100 arranged in an inclined manner is fixedly installed on the top of the material receiving box 1. The opening of the guide plate 100 at one end away from the material receiving box 1 is used to communicate with the discharge port of the molding machine, and the opening of the other end of the guide plate 100 is connected with the feed port 10. A baffle plate 19 is rotatably arranged on the guide plate 100, and the baffle plate 19 is used to control the opening of the guide plate 100 near the feed port 10. A motor driver 191 for driving the baffle plate 19 to rotate is fixedly installed on the material receiving box 1, and the output shaft of the motor driver 191 is connected to the rotating shaft of the baffle plate 19. Two groups of control switches 192 for controlling the forward or reverse rotation of the motor driver 191 are installed on the inner side wall of the feed chamber 12, and both groups of control switches 192 are connected to the motor driver 191 signal. The two groups of control switches 192 are arranged in parallel, and the trigger end of the control switch 192 is pressed to trigger. The trigger end of one set of control switches 192 is installed on the sliding path of the first receiving plate 121. When the first receiving plate 121 is completely moved into the feed chamber 12, the first receiving plate 121 will contact the relative control switch 192, and the control switch 192 will be triggered. The control switch 192 will output a trigger signal to control the motor driver 191 to rotate the baffle plate 19 to the open state. At this time, the four-claw nut dropped from the guide plate 100 can smoothly pass through the feed port 10 into the feed chamber 12. Another set of control switches 192 is installed on the sliding path of the second receiving plate 14. The working principles of the two sets of control switches 192 are the same and will not be repeated here. When the control switch 192 is in an untriggered state, the motor driver 191 will control the baffle plate 19 to rotate to the closed state.

[0040] The implementation principle of the receiving mechanism of the four-claw nut forming machine of the embodiment of the present application is as follows: when the first receiving plate 121 is completely moved into the feed chamber 12 under the drive of the driving component 2, the four-claw nut after processing and forming can smoothly fall into the storage box 122 located on the first receiving plate 121 through the feed port 10. Then, the weight value of the four-claw nut in the storage box 122 is collected and monitored in real time through the gravity sensing control module 3. When the weight value collected by the gravity sensing control module 3 exceeds the preset gravity value, the output end of the gravity sensing control module 3 will output a first control signal to control the driving component 2 to move the first receiving plate 121 into the storage chamber 13. At this time, the first receiving plate 121 stops receiving the four-claw nut, thereby effectively reducing the probability of the four-claw nut near the bottom being squeezed and bent due to greater pressure. The rear four-claw nut will fall onto the second receiving plate 14 located below the first receiving plate 121, and the four-claw nut will continue to be collected by the second receiving plate 14, so there is no need to shut down the four-claw nut forming machine, thus ensuring processing efficiency.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
