Description

Technical Field

[0001] This utility model belongs to the field of areca nut production technology and relates to a quick-change device for areca nut forming molds. Background Technology

[0002] Areca nut forming molds are key equipment in the field of areca nut deep processing. Their core function is to precisely shape areca nut raw materials or semi-finished products into standardized products through hot pressing molding technology, directly serving the large-scale production of dried areca nut, areca nut core, composite tablets and other products.

[0003] Traditional areca nut forming mold cavities mostly adopt a fixed installation structure, which is tightly connected to the mold base and difficult to disassemble. Although this design can ensure the stability of the initial processing, when dealing with the production needs of multiple types of areca nuts, it is easy to cause long-term downtime of the production line due to the large amount of time required to change the cavity each time, thus reducing production efficiency. Therefore, a quick change device for areca nut forming molds is proposed to address the above problems. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the cavity of traditional areca nut forming molds mostly adopts a fixed installation structure, which is tightly connected to the mold base and difficult to disassemble. Although this design can ensure the stability of the initial processing, when dealing with the production needs of multiple types of areca nuts, it is easy to spend a lot of time changing the cavity each time, which leads to long-term shutdown of the production line and reduced production efficiency.

[0005] The present invention discloses a quick-change device for betel nut forming mold, comprising a base plate, a hollow concave base for forming mold mounted on the top surface of the base plate, a quick-release component provided in the middle of the hollow concave base for forming mold, a forming plate connected to the middle of the hollow concave base for forming mold via the quick-release component, and a forming cavity formed in the middle of the forming plate.

[0006] The quick-release assembly includes a tray, multiple sets of ventilation holes, two sets of protective outer boxes, two sets of first threaded rods, and two sets of second threaded rods. The bottom of the tray is fixed to the hollow part of the hollow concave base of the molding mold. The multiple ventilation holes are all opened on one side of the hollow concave base of the molding mold. The two protective outer boxes are respectively connected to the two ends of the hollow concave base of the molding mold. The middle parts of the two first threaded rods are respectively threaded to the two sides of one end of the hollow concave base of the molding mold. The two second threaded rods are respectively threaded to the two sides of the other end of the hollow concave base of the molding mold. The two first threaded rods and the two sets of second threaded rods have opposite thread directions.

[0007] The quick-release assembly also includes a dual-axis motor, four sets of extrusion plates, and four sets of circular threaded sleeves. The bottom of the dual-axis motor is mounted on the top of the support plate. The output ends of the dual-axis motor are rotatably connected to the middle of the two ends of the hollow concave base of the forming mold. The four extrusion plates are respectively fixed to the ends of the two sets of second threaded rods and the two sets of first threaded rods that are close to each other. The four circular threaded sleeves are respectively threaded to the ends of the two sets of first threaded rods and the two sets of second threaded rods that are far apart from each other. Each of the four circular threaded sleeves is provided with a limit mechanism in the middle.

[0008] The quick-release assembly also includes four sets of first synchronous pulleys, four sets of second synchronous pulleys, and four sets of synchronous belts. The four first synchronous pulleys are respectively installed in the middle of the four sets of circular threaded sleeves. The four second synchronous pulleys are respectively installed at the output ends of the dual-axis motor. One end of the four synchronous belts is respectively sleeved in the middle of the four sets of second synchronous pulleys, and the other end of the four synchronous belts is respectively sleeved in the middle of the four sets of first synchronous pulleys.

[0009] The limiting mechanism includes eight driven shafts and four limiting discs. One end of each of the eight driven shafts is fixed to the middle of the four sets of circular threaded sleeves, and the middle parts of the four limiting discs are respectively fixed to both sides of the hollow concave base of the forming mold.

[0010] The limiting mechanism also includes four sets of arc-shaped limiting grooves and eight sets of arc-shaped limiting plates. The four arc-shaped limiting grooves are respectively opened in the middle of the four sets of limiting discs, and the eight arc-shaped limiting plates are respectively fixed to the end of the eight sets of driven shafts away from the circular threaded sleeve, and the eight sets of arc-shaped limiting plates are respectively in contact with the four sets of arc-shaped limiting grooves.

[0011] Compared with the prior art, the beneficial effects of this utility model are: by setting up quick-release components, the time for changing the molding plate can be reduced, thereby reducing the downtime of the equipment. At the same time, it can also reduce the situation where the equipment is easily damaged due to the complexity of disassembly. This shortens the production preparation time, improves the equipment utilization rate and the production efficiency of areca nuts, and ultimately achieves efficient switching of multi-variety areca nut processing and a qualitative leap in overall production efficiency.

[0012] With the setting of the limiting mechanism, the position of the circular threaded sleeve can be restricted, thereby assisting the circular threaded sleeve to drive the first threaded rod and the second threaded rod to screw in or out at both ends of the hollow concave base of the forming mold, so as to cooperate with the quick-release component to complete the work stably and reliably.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] Example 1: As Figures 1 to 7 As shown, a quick-change device for betel nut forming mold includes a base plate 1. A hollow concave base 11 for forming mold is mounted on the top surface of the base plate 1. A quick-release component is provided in the middle of the hollow concave base 11. A forming plate 12 is connected to the middle of the hollow concave base 11 through the quick-release component. A forming cavity 13 is opened in the middle of the forming plate 12.

[0028] The quick-release assembly includes a tray 2, multiple sets of ventilation holes 21, two sets of protective outer boxes 22, two sets of first threaded rods 23, and two sets of second threaded rods 24. The bottom of the tray 2 is fixed to the hollow part in the middle of the hollow concave base 11 of the molding mold. Multiple ventilation holes 21 are opened on one side of the hollow concave base 11 of the molding mold. The two protective outer boxes 22 are respectively connected to the two ends of the hollow concave base 11 of the molding mold. The middle parts of the two first threaded rods 23 are respectively threaded to the two sides of one end of the hollow concave base 11 of the molding mold. The two second threaded rods 24 are respectively threaded to the two sides of the other end of the hollow concave base 11 of the molding mold. The threads of the two first threaded rods 23 and the two sets of second threaded rods 24 are opposite in direction.

[0029] The quick-release assembly also includes a dual-axis motor 3, four sets of extrusion plates 31, and four sets of circular threaded sleeves 32. The bottom of the dual-axis motor 3 is mounted on the top of the support plate 2. The output ends of the dual-axis motor 3 are rotatably connected to the middle of the two ends of the hollow concave base 11 of the forming mold. The four extrusion plates 31 are respectively fixed to the ends of the two sets of second threaded rods 24 and the two sets of first threaded rods 23 that are close to each other. The four circular threaded sleeves 32 are respectively threaded to the ends of the two sets of first threaded rods 23 and the two sets of second threaded rods 24 that are far apart from each other. Each of the four circular threaded sleeves 32 is provided with a limit mechanism in the middle.

[0030] The quick-release assembly also includes four sets of first synchronous pulleys 4, four sets of second synchronous pulleys 41, and four sets of synchronous belts 42. The four first synchronous pulleys 4 are respectively installed in the middle of the four sets of circular threaded sleeves 32. The four second synchronous pulleys 41 are respectively installed at the output ends of the two shaft motors 3. One end of the four synchronous belts 42 is respectively sleeved in the middle of the four sets of second synchronous pulleys 41, and the other end of the four synchronous belts 42 is respectively sleeved in the middle of the four sets of first synchronous pulleys 4.

[0031] During operation, when the molding plate 12 needs to be disassembled and replaced, the dual-axis motor 3 can be driven to rotate its output ends. The torque generated when the output ends of the dual-axis motor 3 rotate is transmitted to the circular threaded sleeve 32 through the second synchronous pulley 41, the synchronous belt 42 and the first synchronous pulley 4. This causes the circular threaded sleeve 32 to rotate with one end of the first threaded rod 23 and the second threaded rod 24 respectively. During the rotation, the circular threaded sleeve 32 is affected by the limiting mechanism, which restricts the movement trajectory of the circular threaded sleeve 32, so that the circular threaded sleeve 32 rotates without changing its own position. This causes the second threaded rod 24 and the first threaded rod 23 to screw out from both ends of the hollow concave base 11 of the molding mold. When the second threaded rod 24 and the first threaded rod 23 screw out, they will drive the extrusion plate 31 to move synchronously, so that the four sets of extrusion plates 31 gradually move away. At this time, the two sides of the molding plate 12 will separate from the extrusion plate 31, so that the molding plate 12 has no fixed point, and the molding plate 12 can be removed and replaced.

[0032] After replacement, the output ends of the dual-axis motor 3 can be driven to rotate in the opposite direction, thereby driving the first threaded rod 23 and the second threaded rod 24 to rotate in reverse. This causes the four sets of extrusion plates 31 to gradually approach and clamp the replaced molding plate 12. The support plate 2 can support the dual-axis motor 3, thereby improving the stability of the dual-axis motor 3. The ventilation hole 21 can improve the ventilation effect between the hollow part of the molding mold hollow concave base 11 and the outside. The protective outer box 22 can protect the components at both ends of the molding mold hollow concave base 11, reducing their contact with the outside.

[0033] This step, through the setting of quick-release components, can reduce the time for replacing the forming plate 12, thereby reducing the downtime of the equipment. It can also reduce the possibility of partial damage to the equipment due to the complexity of disassembly, thereby shortening the production preparation time, improving equipment utilization and the production efficiency of areca nuts, and ultimately achieving efficient switching between processing multiple varieties of areca nuts and a qualitative leap in overall production efficiency.

[0034] Example 2: Figures 3-8 As shown, the limiting mechanism includes eight sets of driven shafts 5 and four sets of limiting discs 51. One end of each of the eight driven shafts 5 is fixed to the middle of the four sets of circular threaded sleeves 32, and the middle parts of the four limiting discs 51 are respectively fixed to the two sides of the hollow concave base 11 of the forming mold.

[0035] The limiting mechanism also includes four sets of arc-shaped limiting grooves 6 and eight sets of arc-shaped limiting plates 61. The four arc-shaped limiting grooves 6 are respectively opened in the middle of the four sets of limiting discs 51, and the eight arc-shaped limiting plates 61 are respectively fixed to the end of the eight sets of driven shafts 5 away from the circular threaded sleeve 32, and the eight sets of arc-shaped limiting plates 61 are respectively in contact with the four sets of arc-shaped limiting grooves 6.

[0036] During operation, when the circular threaded sleeve 32 rotates, it will drive the driven shaft 5 to move synchronously. The movement of the driven shaft 5 will also drive the arc-shaped limiting plate 61 to slide in the middle of the arc-shaped limiting groove 6. At this time, with the cooperation of the arc-shaped limiting groove 6 and the arc-shaped limiting plate 61, the movement trajectory of the circular threaded sleeve 32 can be restricted by the driven shaft 5, so that the position of the circular threaded sleeve 32 remains unchanged when it rotates.

[0037] This step, through the setting of the limiting mechanism, can restrict the position of the circular threaded sleeve 32, thereby assisting the circular threaded sleeve 32 to drive the first threaded rod 23 and the second threaded rod 24 to screw in or out at both ends of the hollow concave base 11 of the forming mold, so as to cooperate with the quick-release assembly to complete the work stably and reliably.
