Description

Technical Field

[0001] This invention belongs to the field of mold-moving arm technology, and specifically relates to a rotary mold-moving arm. Background Technology

[0002] The manufacture and processing of goods often require molds. If the same machine is used to process different items, the molds need to be changed frequently. Molds are relatively heavy, especially the molds for manufacturing and processing large items. They cannot be moved by hand alone. Special auxiliary equipment is needed to assist equipment such as stackers and cranes in changing the molds. The mold moving arm is one such auxiliary equipment.

[0003] However, in the existing technology, the existing mold-moving arm cannot be adjusted, which causes the items conveyed on the upper side to only move forward in a rigid straight line. Furthermore, the existing mold-moving arm cannot be rotated and cannot limit the movement of the items conveyed on the upper side. Summary of the Invention

[0004] The purpose of this invention is to provide a rotary mold-shifting arm, which aims to solve the problems of existing mold-shifting arms being unable to be adjusted, resulting in the upper conveyed items being able to only move forward in a rigid straight line, and existing mold-shifting arms being unable to rotate and limit the movement of the upper conveyed items.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A rotary mold transfer arm, comprising:

[0007] Two support plates, each with a device housing fixedly connected to its top end; each of the device housings has two first square grooves at its top end; and multiple rollers are rotatably connected to the inner walls of both sides of the two first square grooves.

[0008] An adjusting mechanism includes a limiting component, a first arc-shaped rod, a second arc-shaped rod, a third arc-shaped rod, and a fourth arc-shaped rod. The first and second arc-shaped rods are respectively hinged to the adjacent ends of two support plates via hinge shafts. A first rotating rod is rotatably connected to the adjacent ends of the first and second arc-shaped rods. The fourth and third arc-shaped rods are respectively fixedly connected to the adjacent ends of the two support plates. A second rotating rod is rotatably connected to the adjacent ends of the two fourth and third arc-shaped rods. The limiting component is disposed between two device housings, and the limiting component is connected to the device housings to limit the movement of the transported items.

[0009] As a preferred embodiment of the present invention, the limiting component includes a first limiting plate, a second limiting plate, a second square groove, and a motor. There are two second square grooves and two motors. The first limiting plate and the second limiting plate are rotatably connected to the near ends of the two device housings. The two second square grooves are respectively opened at the top of the device housing. The two motors are respectively fixedly connected to the inner wall of one side of the two second square grooves. The output shafts of the two motors slide through the inner wall of one side of the second square groove and are fixedly connected to the far ends of the first limiting plate and the second limiting plate.

[0010] As a preferred embodiment of the present invention, a second connecting plate is fixedly connected to the adjacent ends of the two device housings. Two second threaded holes are threadedly connected to the inner walls of both ends of the second connecting plate, and the four second threaded holes are respectively threaded to the adjacent ends of the two device housings.

[0011] As a preferred embodiment of the present invention, each of the two support plates has two second bolts at both ends, and each of the four second bolts is threaded with a first bolt.

[0012] As a preferred embodiment of the present invention, a third connecting plate is fixedly connected to one side of each of the two device housings, and a fourth threaded hole is provided on one side of each of the third connecting plates. A first connecting plate is fixedly connected to one side of each of the two third connecting plates, and a third threaded hole is provided on one side of each of the two first connecting plates.

[0013] As a preferred embodiment of the present invention, one of the support plates has two first threaded holes at its top end, and the other support plate has two second threaded holes at its top end.

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

[0015] 1. In this solution, the operator can use a PLC controller to control the operation of two motors. When the two motors are running, they will drive the second limit plate and the first limit plate fixed on the surface to rotate slightly. The operator can change them according to their needs to achieve the effect of limiting the items being transported on the upper side of the device shell.

[0016] 2. In this solution, when it is necessary to fix the bottom of the support plate, the operator can rotate the second threaded hole to make it rotate inside the second connecting plate and move it towards the adjacent ends of the two device shells, thereby achieving the effect of firmly fixing the second threaded hole to the adjacent ends of the device shells and increasing its supporting force.

[0023] 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.

[0024] Example 1

[0025] Please see Figure 1-4 The present invention provides the following technical solutions:

[0026] A rotary mold transfer arm, comprising:

[0027] Two support plates 1, each with a device housing 21 fixedly connected to its top. Each device housing 21 has two first square grooves 4 at its top, and multiple rollers 3 are rotatably connected to the inner walls of both sides of the two first square grooves 4.

[0028] The adjustment mechanism includes a limiting component, a first arc-shaped rod 8, a second arc-shaped rod 9, a third arc-shaped rod 15, and a fourth arc-shaped rod 16. The first arc-shaped rod 8 and the second arc-shaped rod 9 are respectively hinged to the adjacent ends of the two support plates 1 via hinge shafts. A first rotating rod is rotatably connected to the adjacent ends of the first arc-shaped rod 8 and the second arc-shaped rod 9. The fourth arc-shaped rod 16 and the third arc-shaped rod 15 are respectively fixedly connected to the adjacent ends of the two support plates 1. A second rotating rod is rotatably connected to the adjacent ends of the two fourth arc-shaped rods 16 and the third arc-shaped rod 15. The limiting component is located between the two device housings 21, and the limiting component and the device housing 21 are connected to limit the transported items.

[0029] In a specific embodiment of the present invention, the two support plates 1 are concave in shape, and the two first limiting plates 6 and the second limiting plate 7 are respectively rotatably connected to the near ends of the two device housings 21. The operator can use the first limiting plates 6 and the second limiting plates 7 to limit the transported items. The operator can use a PLC controller to control the operation of the two motors 20. When the two motors 20 are running, they will respectively drive the surface-fixed second limiting plate 7 and the first limiting plate 6 to rotate slightly, which can be adjusted according to the operator's needs. Multiple rollers 3 are cylindrical and rotate evenly on the inner walls of the two first square grooves 4, which can be adjusted according to the operator's needs. The specific number of rollers 3 needs to be selected. The third threaded hole 13 is fixed to one side of the third connecting plate 12 by welding. The third threaded hole 13 is opened on one side of the first connecting plate 18. The third threaded hole 13 is used to install a strong bolt. The third connecting plate 12 needs to be firmly fixed to the wall. The operator can rotate the bolt to make it rotate in the threaded hole and then extend it to one side of the wall, thereby achieving the effect of fixing the third connecting plate 12. It should be noted that the specific model of motor 20 used shall be selected by the relevant personnel skilled in the art. The above-mentioned motor 20, etc., are all existing technologies and will not be elaborated in this solution.

[0030] Please refer to the details. Figure 1-4 The limiting assembly includes a first limiting plate 6, a second limiting plate 7, a second square groove 19, and a motor 20. There are two second square grooves 19 and two motors 20. The first limiting plate 6 and the second limiting plate 7 are rotatably connected to the close ends of the two device housings 21 respectively. The two second square grooves 19 are respectively opened at the top of the device housing 21. The two motors 20 are respectively fixedly connected to the inner wall of one side of the two second square grooves 19. The output shafts of the two motors 20 slide through the inner wall of one side of the second square groove 19 and are fixedly connected to the far ends of the first limiting plate 6 and the second limiting plate 7 respectively.

[0031] In this embodiment, the operator can use a PLC controller to control the operation of two motors 20. Then, the output shafts of the two motors 20 respectively drive the first limiting plate 6 and the second limiting plate 7 on the surface to rotate. The operator can select the rotation angle of the first limiting plate 6 and the second limiting plate 7.

[0032] Please refer to the details. Figure 1-3 A second connecting plate 10 is fixedly connected to the adjacent ends of the two device housings 21. Two second threaded holes 11 are threadedly connected to the inner walls of both ends of the second connecting plate 10. The four second threaded holes 11 are respectively threaded to the adjacent ends of the two device housings 21.

[0033] In this embodiment: when it is necessary to fix the bottom of the support plate 1, the operator can rotate the second threaded hole 11 to make it rotate inside the second connecting plate 10 and move it toward the close ends of the two device shells 21, thereby achieving the effect of firmly fixing the second threaded hole 11 to the close ends of the device shells 21 and increasing its supporting force.

[0034] Please refer to the details. Figure 3 Two second bolts 17 are provided at both ends of the two support plates 1, and each of the four second bolts 17 is threaded with a first bolt 2.

[0035] In this embodiment: by rotating the first bolt 2, it rotates on the inner circumference of the second bolt 17, and then the first bolt 2 will rotate to both ends of the device housing 21 through the second bolt 17, thereby fixing the support plate 1 to both ends of the device housing 21.

[0036] Please refer to the details. Figure 1 Each of the two device housings 21 is fixedly connected to one side of a third connecting plate 12. A fourth threaded hole 14 is provided on one side of the third connecting plate 12. Each of the two third connecting plates 12 is fixedly connected to one side of a first connecting plate 18. Each of the two first connecting plates 18 is provided with a third threaded hole 13 on one side of its side.

[0037] In this embodiment: the third connecting plate 12 is square and fixed to one side of the two device housings 21. The fourth threaded hole 14 is used to install bolts. The first connecting plate 18 is fixed to one side of the third connecting plate 12 by welding. The third threaded hole 13 is opened on one side of the first connecting plate 18 and is used to install bolts. The operator can select the position of the first connecting plate 18 installed on the third connecting plate 12.

[0038] Please refer to the details. Figure 1 One of the support plates 1 has two first threaded holes 5 at its top end, and the other support plate 1 has two second threaded holes 11 at its top end.

[0039] In this embodiment, the first threaded hole 5 and the second threaded hole 11 are respectively opened at the top of the two support plates 1. The first threaded hole 5 and the second threaded hole 11 are used to install bolts. When it is necessary to fix the support plate 1 on the ground, the operator can rotate the bolts to extend it to the upper side of the ground to achieve the effect of fixing the support plate 1, thereby making the device more stable when bearing force.

[0040] The working principle and usage process of this invention: When the device needs to be adjusted, the operator first needs to turn the second threaded hole 11 out of the second connecting plate 10. Then, the operator manually pulls the support plate 1 to adjust it to the required position. The support plate 1 pulls the ground force, causing the upper motor 20 to swing in an arc shape, which in turn drives the fourth arc rod 16. The fourth arc rod 16 swings through the hinge shaft, and then the fourth arc rod 16 rotates above the third arc rod 15 through the second rotating rod. The operator can select the length of the fourth arc rod 16 and the third arc rod 15. When the device shell 21 swings, it also drives the first arc rod 8 to rotate. When the first arc rod 8 rotates, it drives the first rotating rod to rotate. The rod rotates at the bottom end of the second arc-shaped rod 9. The first arc-shaped rod 8 and the second arc-shaped rod 9 are fixed at opposite ends of the device housing 21 by a hinge shaft. The operator can also select the length of the first arc-shaped rod 8 and the second arc-shaped rod 9. After selection, the operator uses the PLC controller to control the two motors 20 to run. When the two motors 20 are running, they will drive the first limiting plate 6 and the second limiting plate 7 fixed on the surface to rotate slightly. The operator can use the PLC controller to control the motors 20 to select the angle of the first limiting plate 6 and the second limiting plate 7, so as to make the limiting effect of the transported items better and more flexible when transporting items.

[0041] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
