Description

Technical Field

[0001] This utility model relates to a material loading and compaction device. Background Technology

[0002] Currently, the production of oil filters requires filling and compacting materials into the filter housing; the production of fireworks requires filling and compacting materials into the fireworks tube; and the processing of projectiles also requires filling and compacting propellant into the projectile. This demonstrates that many products require filling and compacting materials within their casings during production. Some existing filling and compaction devices use punches to press the material into the casing. In actual production, it has been found that to improve the compaction effect, the punch needs to be locked after it reaches its final position to maintain pressure for a period of time. This allows for tighter compaction and improves the compaction effect. However, most existing filling and compaction devices cannot lock the punch after it reaches its final position. For example, Chinese patent CN117029588A uses a punch to compact the propellant charge inserted into the projectile, but it cannot lock the punch after it reaches its final position to maintain pressure, thus affecting the compaction effect. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a material loading and compaction device that can lock the position of the punch after the punch is pressed down to the position so as to maintain pressure on the material in the shell, thereby improving the compaction effect of the material.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a material loading and compaction device, including a guide sleeve, a punch, at least one locking hook component and an elastic element corresponding to the locking hook component;

[0005] The guide sleeve is provided with a loading channel, and the guide sleeve is used to connect to the loading port of the shell so that material can be loaded into the shell through the loading channel;

[0006] The punch has a pressure bar portion that is adapted to the loading channel and is used to extend into the loading channel to compact the material.

[0007] The locking hook component is rotatably connected to the punch and has a locked position and an unlocked position during rotation;

[0008] The elastic element is installed between the punch and the corresponding locking hook component and is used to drive the corresponding locking hook component to rotate toward the locked position;

[0009] The guide sleeve is also provided with a stepped portion, which is used to abut against the locking hook component and guide the locking hook component to rotate and open to the unlock position when the pressure rod is inserted into the loading channel. The locking hook component is used to rotate to the locking position under the drive of the elastic element when the pressure rod is inserted into the loading channel and hooks the stepped portion, thereby locking the position of the punch in the guide sleeve.

[0010] Furthermore, the lower end of the locking hook component is provided with a guide slope. The step portion is used to abut against the guide slope portion during the process of the pressure rod portion extending into the loading channel to guide the locking hook component to rotate and open to the unlock position. The step portion is also used to disengage from the guide slope portion when the pressure rod portion is extended into the loading channel, so that the locking hook component rotates to the locking position under the drive of the elastic element and hooks the step portion.

[0011] Furthermore, the locking hook component is provided with a claw for abutting against the lower end of the step portion to hook the step portion, and the guide bevel is located below the claw.

[0012] Furthermore, the upper end of the punch is provided with a clamping part for external robotic arm to hold.

[0013] Furthermore, the loading and compaction device also includes:

[0014] The unlocking cover has an unlocking ramp at its lower end that corresponds to the locking hook component. The unlocking cover is used to be moved to the outside of the clamping part and to press the upper end of the locking hook component with the unlocking ramp, thereby driving the locking hook component to rotate to the unlocking position against the elastic force of the elastic element, so that the locking hook component can release itself from the step part.

[0015] A clamping mechanism is connected to the unlocking cover and is used to clamp the clamping part when the upper end of the lock hook component is pressed against the unlocking ramp and the lock hook component is rotated to the unlocking position.

[0016] Furthermore, the upper end of the locking hook component is provided with an arc-shaped portion for abutting against the unlocking ramp.

[0017] Further, a specific structure of the clamping mechanism is provided, the clamping mechanism including a left clamping block, a left cylinder, a right clamping block, and a right cylinder;

[0018] The unlocking cover is provided with a left clamping hole and a right clamping hole;

[0019] The left clamp is slidably connected to the unlocking cover;

[0020] The left cylinder is connected to the unlocking cover and to the left clamping block, and is used to drive the left clamping block through the left clamping hole and abut against one end of the clamping part.

[0021] The right clamp is slidably connected to the unlocking cover;

[0022] The right cylinder is connected to the unlocking cover and to the right clamping block, and is used to drive the right clamping block through the right clamping hole and abut against the other end of the clamping part.

[0023] Furthermore, the punch has a flange portion that protrudes radially outward, the locking hook component is rotatably connected to the flange portion, and the elastic element is installed between the flange portion and the corresponding locking hook component.

[0024] Furthermore, the outer periphery of the flange is provided with a circumferential positioning notch, and the bottom of the pressure rod is provided with an arc-shaped recess.

[0025] Furthermore, the lower end of the guide sleeve is provided with a threaded portion for connecting with the loading port on the housing.

[0026] After adopting the above technical solution, the guide sleeve is first installed and connected to the loading port of the housing. A certain amount of material is loaded into the housing through the loading channel. After the material is full, some material will overflow into the loading channel. At this time, the pressure rod of the punch can be inserted into the loading channel. During the process of pressing down the punch, the bottom of the pressure rod will press down on the material in the loading channel, thereby pressing and compacting the material in the housing. During the process of pressing down the punch, the pressure rod gradually extends into the loading channel, and then the step part will abut against the locking hook component and guide the locking hook component to rotate and open to the unlock position. When the punch is pressed down to the end, the pressure rod part also extends into the loading channel. At this time, the locking hook component will rotate to the locking position under the drive of the elastic element and hook the step part, thereby locking the position of the punch in the guide sleeve. Therefore, after the punch is pressed down to the position, the locking hook component can hook the step portion and lock the position of the punch, thereby maintaining the pressure on the compacted material in the housing for a period of time, thus improving the compaction effect of the material.

[0035] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0036] like Figures 1-8 As shown, a material loading and compaction device includes a guide sleeve 1, a punch 2, at least one locking hook component 3, and an elastic element 4 corresponding to the locking hook component 3;

[0037] The guide sleeve 1 is provided with a loading channel 5. The guide sleeve 1 is used to connect to the loading port of the housing 6 so that material can be loaded into the housing 6 through the loading channel 5.

[0038] The punch 2 has a pressure bar 7 that is adapted to the loading channel 5 and is used to extend into the loading channel 5 to compact the material.

[0039] The locking hook component 3 is rotatably connected to the punch 2 and has a locked position and an unlocked position during rotation;

[0040] The elastic element 4 is installed between the punch 2 and the corresponding locking hook component 3 and is used to drive the corresponding locking hook component 3 to rotate toward the locked position;

[0041] The guide sleeve 1 is also provided with a stepped portion 8. The stepped portion 8 is used to abut against the locking hook component 3 during the process of the pressure rod portion 7 extending into the loading channel 5 and guide the locking hook component 3 to rotate and open to the unlocked position. The locking hook component 3 is used to rotate to the locked position under the drive of the elastic element 4 when the pressure rod portion 7 is fully inserted into the loading channel 5 and hooks the stepped portion 8, thereby locking the position of the punch 2 in the guide sleeve 1. Specifically, the guide sleeve 1 is first installed and connected to the loading port of the housing 6. A certain amount of material is loaded into the housing 6 through the loading channel 5. After the material is full, some material will overflow into the loading channel 5. At this time, the pressure rod portion 7 on the punch 2 can be extended into the loading channel 5. During the process of pressing down the punch 2, the bottom of the pressure rod portion 7 will press down on the material in the loading channel 5, thereby pressing and compacting the material in the housing 6. During the downward pressing of the punch 2, the pressure rod 7 gradually extends into the loading channel 5. The stepped portion 8 then abuts against the locking hook component 3, guiding it to rotate and open towards the unlocked position. When the punch 2 is fully depressed, the pressure rod 7 also extends into the loading channel 5. At this point, the locking hook component 3, driven by the elastic element 4, rotates to the locked position and hooks the stepped portion 8, thus locking the position of the punch 2 within the guide sleeve 1. Therefore, after the punch 2 is fully depressed, the locking hook component 3 hooks the stepped portion 8, locking the position of the punch 2 and maintaining pressure on the compacted material in the housing 6 for a period of time, thereby improving the compaction effect. In this embodiment, the stepped portion 8 protrudes radially outward, and multiple locking hook components 3 are evenly distributed circumferentially. The elastic element 4 corresponds one-to-one with the locking hook component 3.

[0042] like Figures 1-8As shown, the lower end of the locking hook component 3 is provided with a guide slope 9. The step portion 8 is used to abut against the guide slope 9 during the process of the pressure rod portion 7 extending into the loading channel 5 to guide the locking hook component 3 to rotate and open to the unlock position. The step portion 8 is also used to disengage from the guide slope 9 when the pressure rod portion 7 is inserted into the loading channel 5, so that the locking hook component 3 rotates to the locking position under the drive of the elastic member 4 and hooks the step portion 8. Specifically, in the initial stage when the pressure rod 7 extends into the loading channel 5, the step 8 will not contact the guide slope 9. When the pressure rod 7 extends to a certain position, the step 8 abuts against the guide slope 9. Then, as the pressure rod 7 continues to extend, the locking hook component 3 is guided to the unlock position and rotates to open. When the pressure rod 7 is fully extended, the step 8 disengages from the guide slope 9. At this time, the locking hook component 3 rotates to the locked position under the drive of the elastic element 4 and hooks the step 8, thereby locking the position of the punch 2 in the guide sleeve 1 so as to maintain pressure on the material.

[0043] like Figure 1 , 2 As shown in 3, 4, 5, and 7, the locking hook component 3 is provided with a hook claw 10 for abutting against the lower end of the step portion 8 to hook the step portion 8, and the guide inclined portion 9 is provided below the hook claw 10.

[0044] like Figures 1-6 As shown, the upper end of the punch 2 is provided with a clamping part 11 for external robotic arm to hold.

[0045] like Figure 4 , 5 As shown, the loading and compaction device may further include an unlocking cover 12 and a clamping mechanism;

[0046] The lower end of the unlocking cover 12 is provided with an unlocking ramp 13 corresponding to the locking hook component 3. The unlocking cover 12 is used to be moved to the outside of the clamping part 11 and to make the unlocking ramp 13 press against the upper end of the locking hook component 3, thereby driving the locking hook component 3 to rotate to the unlocking position against the elastic force of the elastic member 4, so that the locking hook component 3 can release itself from hooking the step part 8.

[0047] The clamping mechanism is connected to the unlocking cover 12 and is used to clamp the clamping part 11 when the unlocking inclined surface 13 presses against the upper end of the locking hook component 3 and drives the locking hook component 3 to rotate to the unlocking position.

[0048] Specifically, after the guide sleeve 1 is installed and connected to the loading port of the housing 6, a certain amount of material can be loaded into the housing 6 from the loading channel 5. After the material is loaded, the external robot grips the gripping part 11 and drives the punch 2 to move so that the pressure rod part 7 on the punch 2 extends into the loading channel 5 and presses the material downward. When the pressure rod part 7 is in place in the loading channel 5 and the locking hook part 3 hooks the step part 8 to maintain pressure, the external robot releases the gripping part 11. Then, when unlocking is required, the external robot grabs the unlocking cover 12 and drives the unlocking cover 12 to move so that the unlocking cover 12 is placed outside the gripping part 11. Then, the unlocking cover 12 is driven to move downward so that the unlocking inclined surface 13 presses against the upper end of the locking hook part 3, thereby driving the locking hook part 3 to rotate against the elastic force of the elastic member 4 to the unlocking position. At this time, the locking hook part 3 releases its hook from the step part 8. Then, the clamping mechanism clamps the clamping part 11 on the punch 2, and then the external robotic arm drives the unlocking cover 12 to move upward, thereby driving the punch 2 to move upward together and be pulled out through the clamping mechanism. In this embodiment, the unlocking inclined surface 13 corresponds one-to-one with the locking hook component 3.

[0049] like Figure 1 , 2 As shown in 3, 4, 5, and 7, the upper end of the locking hook component 3 is provided with an arc-shaped surface 14 for abutting against the unlocking inclined surface 13; specifically, the unlocking inclined surface 13 abuts against the arc-shaped surface 14, thereby better driving the locking hook component 3 to overcome the elastic force of the elastic member 4 and rotate to the unlocking position, thereby causing the locking hook component 3 to release from hooking the step portion 8.

[0050] like Figure 4 , 5As shown, the clamping mechanism may include a left clamping block 15, a left cylinder, a right clamping block 16, and a right cylinder; wherein, the unlocking cover 12 is provided with a left clamping hole and a right clamping hole 17, the left clamping block 15 is slidably connected to the unlocking cover 12, the left cylinder is connected to the unlocking cover 12 and connected to the left clamping block 15 and is used to drive the left clamping block 15 through the left clamping hole and abut against one end of the clamping part 11; the right clamping block 16 is slidably connected to the unlocking cover 12, the right cylinder is connected to the unlocking cover 12 and connected to the right clamping block 16 and is used to drive the right clamping block 16 through the right clamping hole 17 and abut against the other end of the clamping part 11, thereby clamping the clamping part 11 by the left clamping block 15 and the right clamping block 16, thereby enabling the punch 2 to move upward together with the unlocking cover 12. Of course, in some embodiments, a wide-finger cylinder can be used instead of the left cylinder and the right cylinder. The wide-finger cylinder is connected to the unlocking cover 12 and is connected to the left clamping block 15 and the right clamping block 16 respectively, and is used to drive the left clamping block 15 and the right clamping block 16 to move towards each other to clamp the clamping part 11.

[0051] like Figures 1-6 As shown, the punch 2 has a flange portion 18 that protrudes radially outward. The locking hook component 3 is rotatably connected to the flange portion 18, and the elastic element 4 is installed between the flange portion 18 and the corresponding locking hook component 3. In this embodiment, the elastic element 4 can be a torsion spring, which drives the corresponding locking hook component 3 to rotate toward the locked position. The flange portion 18 is located between the pressure rod portion 7 and the clamping portion 11. The flange portion 18 has mounting grooves 19 that correspond one-to-one with the locking hook components 3, and the locking hook components 3 are rotatably connected in the corresponding mounting grooves 19.

[0052] like Figures 1-8 As shown, the outer periphery of the flange portion 18 is provided with a circumferential positioning notch 20, and the bottom of the pressure rod portion 7 is provided with an arc-shaped recess 21. Specifically, a special tooling is required when rotating the punch 2. The tooling has a base plate 22 for supporting the punch 2. Multiple limiting posts 23 are connected to the base plate 22. The limiting posts 23 surround the outside of the pressure rod portion 7 and abut against the side wall of the pressure rod portion 7 to position the pressure rod portion 7. A positioning rod 24 is also connected to the base plate 22. The positioning rod 24 cooperates in the circumferential positioning notch 20 to position the punch 2 in the circumferential direction.

[0053] like Figures 1-8 As shown, the lower end of the guide sleeve 1 is provided with a threaded portion 25 for connecting with the loading port on the housing 6; in this embodiment, the upper end of the loading channel 5 is provided with a chamfered portion 26 for guiding the pressure rod portion 7 to extend in.

[0054] In summary, the guide sleeve 1 is first installed and connected to the loading port of the housing 6. A certain amount of material is loaded into the housing 6 through the loading channel 5. After the material is full, some material will overflow into the loading channel 5. At this time, the pressure rod 7 on the punch 2 can be inserted into the loading channel 5. During the process of pressing down the punch 2, the bottom of the pressure rod 7 will press down on the material in the loading channel 5, thereby pressing and compacting the material in the housing 6. During the process of pressing down the punch 2, the pressure rod 7 gradually extends into the loading channel 5, and then the step 8 will abut against the locking hook component 3 and guide the locking hook component 3 to rotate and open to the unlock position. When the punch 2 is pressed down to the end, the pressure rod 7 also extends into the loading channel 5. At this time, the locking hook component 3 will rotate to the locking position under the drive of the elastic element 4 and hook the step 8, thereby locking the position of the punch 2 in the guide sleeve 1. Therefore, after the punch 2 is pressed down into place, the locking hook component 3 can hook the step part 8 and lock the position of the punch 2, thereby maintaining the pressure on the material that is compressed in the housing 6 for a period of time, thus improving the compaction effect of the material.

[0055] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
