Description

Technical Field

[0001] This invention discloses a resin craft production equipment, belonging to the field of craft production technology. Background Technology

[0002] Resin crafts are decorative crafts made from resin as the core raw material, through mold casting, wall hanging, and curing. They are widely used in home decoration, cultural and creative gifts, ornaments and decorations. In the automated production process of resin crafts, the mold rotation and wall hanging molding is the core process. By continuously rotating the mold containing liquid resin, the resin is evenly attached to the inner wall of the mold, ensuring the integrity and beauty of the craft after molding.

[0003] Currently, most conventional resin craft production equipment on the market adopts a single rotating frame structure, which can only accommodate 1-2 molds at a time. This results in low workload and low production efficiency. Furthermore, the rotating mechanism of existing equipment is mostly an integrated transmission structure, with the transmission system starting and stopping synchronously with mold operation. During mold assembly, demolding, and cleaning, the equipment must be stopped and wait, which cannot achieve continuous operation. A lot of production time is wasted, which greatly limits the efficiency of mass production. In addition, the existing mold fixing structure is cumbersome, the mold assembly and disassembly operation is complicated, and the positioning and locking stability is insufficient. During high-speed rotation of the mold, problems such as loosening, displacement, or even falling off are prone to occur, which further affects the stability of production and product quality. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art and to provide a resin craft production equipment.

[0005] This invention achieves the above-mentioned objectives through the following technical solution: a resin craft production equipment, comprising a workbench, a rotating frame, a mold, a transmission mechanism, and a clutch mechanism, characterized in that: two rotating frames are provided and rotatably mounted on the side of the workbench; each rotating frame has two mounting brackets, which are symmetrically distributed at 180° on the rotating frame; the mold is slidably disposed within the mounting bracket; the transmission mechanism includes a transmission rod, a connecting rod, a drive assembly, and an elastic clamping member; the transmission rod has a transmission gear in the middle and first clutch portions at both ends; a fixed shaft is provided on one side of the rotating frame; one end of the connecting rod has a second clutch portion that cooperates with the first clutch portion, and the other end is circumferentially limited and connected to the fixed shaft; the elastic clamping member is used to force the second clutch portion to remain engaged with the first clutch portion. The drive assembly is installed inside the workbench and is used to drive the transmission gear to reciprocate. The clutch mechanism has two sets, which are used to control the power supply between the first clutch part and the second clutch part on the corresponding side. Each clutch mechanism includes a screw rod linked with the transmission gear, a movable component mounted on the screw rod, and a guide rod. The movable component includes a movable seat, a threaded sleeve, and a locking element. The threaded sleeve is threadedly connected to the screw rod and rotatably connected to the movable seat.

The locking element is used to selectively lock the rotation of the threaded sleeve relative to the movable seat. The movable seat is slidably disposed with the guide rod, and the movable seat is also provided with a trigger element, which is used to control the locking state of the locking element according to the moving position of the movable seat.

[0006] Preferably, the drive assembly includes a sliding frame, a first motor, and a toothed gear.

[0007] Preferably, the first clutch part is a concave disc with multiple countersunk holes, and the second clutch part is a convex disc with multiple protrusions that cooperate with the countersunk holes. The elastic clamping member includes a first spring, a first limiting bolt, and a limiting block.

The first spring applies an elastic force toward the first clutch part to the second clutch part.

[0008] Preferably, a washer is provided between the first spring and the connecting rod, and the cross-section of the connecting rod extending into the fixed shaft has a non-circular structure.

[0009] Preferably, the triggering element includes a pressing block and a V-shaped guide groove on the pressing block, and the locking element includes a clamping block and a driving rod. One end of the driving rod is connected to the clamping block, and the other end is placed in the guide groove. The threaded sleeve has a limiting groove that cooperates with the clamping block. The worktable has two positioning plates for installing the transmission rod and the screw. The movable seat is provided with a guide block for installing the pressing block.

One end of the second limiting bolt passes through the guide block and is fixedly connected to the pressing block. The second spring is sleeved on the outside of the second limiting bolt, and both ends of the second spring abut against the pressing block and the guide block, respectively. When the two ends of the pressing block are not subjected to external force, the driving rod is located in the middle of the guide groove, and the clamping block is clamped into the limiting groove on the threaded sleeve under the action of the second spring. When one end of the pressing block abuts against the worktable or the positioning plate, the pressing block moves relative to the movable seat, and the driving rod slides along the guide groove and drives the clamping block to disengage from the limiting groove.

[0010] Preferably, the movable seat is composed of two assembly blocks fixed by bolts, the pushing part is located on one of the assembly blocks, the second clutch part is provided with an annular protrusion, and the guide rod passes through the position between the two assembly blocks.

[0011] Preferably, the rotating frame is further provided with a power component for driving the mold to rotate. The power component includes a second motor, a driving bevel gear and two driven bevel gears. The two driven bevel gears are respectively fixedly connected to two mounting frames through connecting shafts. The second motor is mounted on the rotating frame, and the output shaft of the second motor is fixedly connected to the driving bevel gear. The driving bevel gear meshes with the two driven bevel gears.

[0012] Preferably, the mounting frame is provided with a positioning component for fixing the mold. The positioning component includes a movable ring, a limiting component, and a fastening bolt.

[0013] Preferably, the reciprocating rotation angle of the rotating frame is controlled within 90°.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. Two sets of symmetrically arranged rotating frames are set up. At the same time, through the coordinated cooperation of two sets of clutch mechanisms, the power of the two rotating frames is alternately turned on and off. While one set of rotating frames drives the mold to rotate and form on the wall, the mold of the other set of rotating frames can be disassembled, demolded, and cleaned. The equipment does not need to stop throughout the process, completely eliminating the downtime waiting time of traditional equipment, realizing continuous production line production, and significantly improving the overall production efficiency of resin crafts.

[0016] 2. Through the mechanical linkage of the screw, threaded sleeve, clamping block and pressing block, the engagement and disengagement of the first clutch and the second clutch are precisely controlled. The power clutch has a fast response, stable structure, no need for electronic control assistance, low failure rate and low maintenance cost. Moreover, the simultaneous force application of the moving components on both sides ensures that the cam is subjected to balanced force, avoids offset and jamming, and greatly improves the stability of equipment operation.

Detailed Implementation

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] like Figures 1-9 As shown, a resin craft production equipment includes a workbench 1, a rotating frame 3, a mold 2, a transmission mechanism and a clutch mechanism 7. The workbench 1 is hollow inside to accommodate some transmission components. A rotating frame 3 is rotatably installed on the left and right sides of the workbench 1, and the two rotating frames 3 rotate independently.

[0029] Each rotating frame 3 has two mounting frames 5 that are symmetrically distributed at 180°. The mounting frames 5 are hollow cylindrical structures. The mold 2 can be slidably inserted into the mounting frame 5 and fixed by the positioning part 4. This symmetrical dual-station design allows each rotating frame 3 to install two molds 2 at the same time.

[0030] The transmission mechanism includes a horizontally arranged transmission rod 23, a connecting rod 8, a drive assembly 13, and an elastic clamping member 17. A transmission gear 25 is fixed in the middle of the transmission rod 23, and concave discs serving as first clutch parts 10 are provided at its left and right ends respectively. Each concave disc has a plurality of countersunk holes 31 evenly arranged along the circumference.

[0031] A fixed shaft 51 is fixed on the rotating frame 3. One end of the connecting rod 8 is provided with a convex plate as a second clutch part 9. Multiple protrusions 46 that cooperate with the countersunk hole 31 are evenly provided on the convex plate along the circumference. The other end of the connecting rod 8 has a non-circular cross-section and is embedded in the non-circular hole corresponding to the end face of the fixed shaft 51, thereby realizing circumferential limiting connection, so that the connecting rod 8 can drive the fixed shaft 51 and the rotating frame 3 to rotate synchronously. The elastic clamping member 17 includes a first spring 19, a first limiting bolt 22 and a limiting block 20. One end of the first limiting bolt 22 passes through the limiting block 20 and is fixedly connected to the connecting rod 8. The first spring 19 applies an elastic force to the second clutch part 9 toward the first clutch part 10, forcing the protrusions 46 to remain stuck in the countersunk hole 31, thereby realizing power transmission. At the same time, a gasket 18 is also provided between the first spring 19 and the connecting rod 8 to avoid wear between the first spring 19 and the connecting rod 8 during rotation.

[0032] The drive assembly 13 is installed inside the workbench 1 to drive the transmission gear 25 to reciprocate. Specifically, the drive assembly 13 includes a sliding frame 35, a first motor 36, and a toothed gear 32. Two parallel pressure bars 33 are fixedly installed inside the workbench 1. The sliding frame 35 is horizontally slidably arranged between the two pressure bars 33 and can reciprocate linearly in the horizontal direction. The first motor 36 is fixedly installed on one of the pressure bars 33, and the toothed gear 32 is fixed on its output shaft. The sliding frame 35 has a racetrack-shaped structure with a hollow area in the middle. The toothed gear 32 is located in the hollow area. Multiple first toothed grooves 34 are provided on the upper and lower sides of the inner side of the sliding frame 35. The toothed gear 32 has teeth on only a part of its circumference. When rotating, it can mesh with the upper or lower row of first toothed grooves 34 in sequence. Multiple second toothed grooves 37 are provided on the outer side of the sliding frame 35. These second toothed grooves 37 mesh with the transmission gear 25.

[0033] When the first motor 36 drives the toothed gear 32 to rotate continuously in one direction, the toothed gear 32 alternately meshes with the upper and lower rows of first toothed grooves 34, thereby driving the sliding frame 35 to reciprocate linearly in the horizontal direction. The reciprocating linear motion of the sliding frame 35 is transmitted to the transmission gear 25 through the outer second toothed groove 37, converting it into the reciprocating rotational motion of the transmission gear 25. By designing the number of teeth that mesh between the second toothed groove 37 and the transmission gear 25, the reciprocating rotation angle of the rotating frame 3 can be controlled within a preset range. In this embodiment, it is preferably controlled within 90°. When the mold 2 on the rotating frame 3 rotates to the lowest point, for example, rotating downward to a position of 45°, the resin material in the mold 2 slowly flows towards one end of the mold 2 under the action of gravity. When the mold 2 rotates towards the highest point, for example, rotating upward to a position of 135°, the resin material slowly flows towards the other end. This reciprocating motion allows the resin to cover the inner wall of the mold 2 along its length.

[0034] To achieve independent control of the two rotating frames 3, a set of clutch mechanisms 7 is set on each side of the transmission rod 23. Two positioning plates 6 for supporting the transmission rod 23 are fixed on the inner side of the worktable 1. Each set of clutch mechanisms 7 includes a screw 27 arranged parallel to the transmission rod 23, two movable components 11, a driven gear 26, and two guide rods 28. Two positioning plates 6 are provided on the inner side of the worktable 1. The screw 27 is rotatably connected to the two positioning plates 6. The driven gear 26 is fixed in the middle of the screw 27 and meshes with the transmission gear 25. When the transmission gear 25 rotates, it will drive the driven gear 26 and the screw 27 to rotate synchronously. The two guide rods 28 are fixedly arranged parallel to the screw 27 to guide the linear movement of the movable components 11.

[0035] Each movable component 11 includes a movable seat 24, a threaded sleeve 29, and a locking block 38 as a locking element. The threaded sleeve 29 has a dumbbell-shaped structure with a small diameter in the middle and a large diameter at both ends. Its inner wall is provided with an internal thread that mates with the screw 27. The movable seat 24 is composed of two assembly blocks that are fixed by bolts. The two assembly blocks are engaged at the narrow necks at both ends of the threaded sleeve 29, so that the movable seat 24 and the threaded sleeve 29 are rotatably connected but axially fixed. The outer side of the second clutch 9 is provided with an annular protrusion 45. One of the assembly blocks is integrally formed with a pusher 30 for pushing the annular protrusion 45. The threaded sleeve 29 is threadedly connected to the screw 27. The locking block 38 is slidably disposed in the movable seat 24. The narrow neck of the threaded sleeve 29 is provided with a limiting groove 57 that mates with the end of the locking block 38. The locking block 38 has a tendency to move toward the threaded sleeve 29 under the action of the second spring 40.

[0036] The movable seat 24 is also equipped with a trigger 12 for controlling the engagement state of the clamping block 38 and the limiting groove 57. Specifically, the trigger 12 includes a pressing block 44 and a V-shaped guide groove 43 on the pressing block 44. A guide block 42 is fixedly installed on the movable seat 24. The pressing block 44 slides with the guide block 42, and both ends of the pressing block 44 extend to the outside of the guide block 42, which can abut against the inner wall of the worktable 1 or the side of the positioning plate 6. The sliding direction of the pressing block 44 is parallel to the movement direction of the movable seat 24. One end of the drive rod 39 is fixed to the clamping block 38, and the other end is placed in the V-shaped guide groove 43. One end of the clamping block 38 is provided with a second limiting bolt 41 and a second spring 40. One end of the second limiting bolt 41 passes through the guide block 42 and is fixedly connected to the clamping block 38. The second spring 40 is sleeved on the second limiting bolt 41 and applies a force toward the threaded sleeve 29 to the clamping block 38.

[0037] When neither end of the pressing block 44 is in contact with the worktable 1 or the positioning plate 6, the drive rod 39 is located in the middle of the V-shaped guide groove 43. At this time, under the action of the second spring 40, the end of the clamping block 38 is embedded in the limiting groove 57 of the threaded sleeve 29, locking the rotation of the threaded sleeve 29 relative to the movable seat 24. Even if there is a misalignment between the clamping block 38 and the limiting groove 57, after the nut sleeve rotates a certain angle with the screw 27, the clamping block 38 can be embedded in the limiting groove 57. At this time, the rotation of the screw 27 will drive the threaded sleeve 29 to move along the axial direction of the screw 27. However, due to the locking effect of the clamping block 38, the threaded sleeve 29 cannot rotate on its own. Therefore, the threaded sleeve 29 will drive the entire movable seat 24 to move horizontally and linearly along the guide rod 28.

[0038] When the movable seat 24 moves away from the positioning plate 6, its pushing part 30 abuts against the annular protrusion 45 on the outer side of the second clutch part 9, pushing the second clutch part 9 to move away from the second clutch part 9 against the elastic force of the first spring 19, until the protrusion 46 completely disengages from the countersunk hole 31. At this time, the power transmission is interrupted, and the rotating frame 3 on this side stops rotating. When the movable seat 24 continues to move until one end of its pressing block 44 abuts against the inner wall of the worktable 1, the pressing block 44 and the movable seat 24 move relative to each other. The pressing block 44 is stopped by the pressure, and the movable seat 24 continues to move. At this time, the drive rod 39 slides from the bottom of the V-shaped guide groove 43 to the inclined surface on one side. The inclined surface pushes the drive rod 39 outward, thereby causing the locking block 38 to overcome the force of the second spring 40 and disengage from the limiting groove 57, so that the threaded sleeve 29 is unlocked and rotates synchronously with the screw 27. The movable seat 24 stops moving and remains in this position. The second clutch 9 remains in the state of disengaging from the first clutch 10, and the rotating frame 3 on this side remains stationary.

[0039] Since the threads of the two movable components 11 on the same screw 27 are in the same direction, the two movable components 11 will move synchronously in the same direction when the screw 27 rotates. When the pressing block 44 of one movable component 11 abuts against the worktable 1, the pressing block 44 of the other movable component 11 will abut against the positioning plate 6, causing the corresponding clamping block 38 of the movable component 11 to also disengage from the limiting groove 57. However, its movable seat 24 stops at a position close to the positioning plate 6, and the pushing part 30 does not push the annular protrusion 45. Therefore, the first spring 19 on this side keeps the second clutch part 9 and the first clutch part 10 in contact. In the engaged state, the power of the transmission rod 23 is smoothly transmitted to the rotating frame 3 on that side, so that the rotating frame 3 on that side follows the transmission rod 23 in reciprocating rotation. In this way, while the transmission rod 23 is rotating continuously, one rotating frame 3 can rotate along with it, while the other rotating frame 3 remains stationary. The operator can safely perform operations such as demolding, demolding, and material injection on the mold 2 on the stationary rotating frame 3, while the resin material in the mold 2 on the rotating frame 3 is evenly adhered to the inner wall of the mold 2 during the reciprocating oscillation. The two rotating frames 3 work alternately without stopping the machine, which significantly improves production efficiency.

[0040] To improve the uniformity of resin material adhesion to the inner wall of mold 2, this embodiment adds a self-rotating power component 21. The power component 21 includes a second motor 14, a driving bevel gear 15, and two driven bevel gears 16. There are two driven bevel gears 16, which are fixedly connected to the bottom of two mounting brackets 5 on the same rotating frame 3 through connecting shafts. The second motor 14 is fixedly installed in the middle of the rotating frame 3, and its output shaft is fixedly connected to the driving bevel gear 15. The driving bevel gear 15 meshes with the two driven bevel gears 16 at the same time. When the second motor 14 is started, the driving bevel gear 15 rotates, driving the two driven bevel gears 16 to rotate synchronously. In turn, the two mounting brackets 5 and the mold 2 inside them are driven to rotate through the connecting shaft. This rotational motion is combined with the reciprocating oscillating motion of the rotating frame 3 as a whole, so that all parts of the inner wall of mold 2 can obtain a sufficient and uniform resin coating effect, thereby ensuring the consistency of the wall thickness of the resin craft after curing.

[0041] The positioning component 4 includes a movable ring 50, a limiting component, and a fastening bolt 47. The movable ring 50 is mounted on the outer periphery of the open end of the mounting bracket 5 via the fastening bolt 47. An arc-shaped groove 48 is formed on the movable ring 50. The fastening bolt 47 passes through the arc-shaped groove 48 and connects to a threaded hole on the mounting bracket 5. A actuating part 49 extends radially from the outer side of the movable ring 50. The operator can rotate the movable ring 50 within the central angle range of the arc-shaped groove 48 by pushing and pulling the actuating part 49. The inner wall of the movable ring 50 is an arc surface, and the distance from different positions on this arc surface to the center of the movable ring 50 gradually transitions. A transition surface 52 is formed. The limiting component includes a clamping block 54, a third limiting bolt 53, and a third spring 55. A radial through hole is opened on the side wall of the mounting bracket 5. The clamping block 54 is slidably disposed in the through hole. One end of the third limiting bolt 53 passes through the mounting bracket 5 and is fixedly connected to the clamping block 54. The third spring 55 is sleeved on the third limiting bolt 53. One end of the spring abuts against the mounting bracket 5, and the other end abuts against the clamping block 54, and applies an elastic force to the clamping block 54 toward the transition surface 52 inside the movable ring 50. A notch 56 is provided on the outer wall of the mold 2 at a corresponding position to cooperate with the end of the clamping block 54.

[0042] When installing mold 2, first loosen the fastening bolt 47, and rotate the movable ring 50 through the actuating part 49 so that the section of the transition surface 52 farther from the center is aligned with the clamping block 54. At this time, under the action of the third spring 55, the end of the clamping block 54 retracts into the inner wall of the mounting bracket 5, without obstructing the insertion of mold 2. After sliding mold 2 into the mounting bracket 5 to the predetermined position, rotate the movable ring 50 in the opposite direction so that the section of the transition surface 52 closer to the center gradually presses against the clamping block 54. The clamping block 54 overcomes the elastic force of the third spring 55 and extends towards the center. The end of the movable ring 50 is inserted into the notch 56 of the mold 2, thereby locking the mold 2 inside the mounting frame 5. Finally, tighten the fastening bolt 47 to fix the movable ring 50 at the current angle. When it is necessary to remove the mold 2, loosen the fastening bolt 47 and rotate the movable ring 50 in the opposite direction. The abutment block 54 will automatically disengage from the notch 56 and retract under the action of the third spring 55, so that the mold 2 can be pulled out from the mounting frame 5. The positioning part 4 has a simple structure, quick operation, and reliable locking. It can effectively prevent the mold 2 from accidentally falling off when the mold 2 rotates and revolves at high speed with the mounting frame 5.

[0043] Working principle: The first motor 36 and the second motor 14 are started. The first motor 36 drives the toothed gear 32 to rotate continuously, driving the sliding frame 35 to reciprocate linearly. Through gear meshing, the transmission rod 23 is driven to continuously reciprocate at a fixed angle. The second motor 14 drives the mold 2 to rotate continuously. During normal operation of the equipment, the transmission rod 23 drives the screw 27 to rotate synchronously. Through the mechanical linkage of the clutch mechanism 7, the left and right rotating frames 3 alternately realize the power connection and disconnection: When the power of the left rotating frame 3 is connected, the mold 2 reciprocates with the rotating frame 3 and rotates on its own, completing the uniform coating and molding of resin raw materials in the mold 2. When the power of the right rotating frame 3 is disconnected, the operator can perform demolding, cleaning, loading and locking operations on the right mold 2.

[0044] Once the single-sided mold 2 has finished molding, the clutch mechanism 7 automatically switches to the working state. The rotating frame 3 on the molding side stops and waits for disassembly and assembly, while the mold 2 on the other side, which has been loaded with material, automatically starts working. This cycle repeats continuously, and the equipment does not need to stop throughout the entire process. It always maintains a working state of one set of mold 2 operating and another set of mold 2 being disassembled and assembled, completely eliminating waiting time and greatly improving production efficiency. At the same time, relying on the combined motion of revolution and rotation, it ensures uniform resin molding and improves product quality.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
