Description

Technical Field

[0001] The present application relates to the technical field of material collection, and in particular to a material collecting device. Background Art

[0002] During the production process, film pasting is an important process. The pasted film can not only protect the product, but also provide necessary insulation, shielding and other functions. However, the residual film and waste materials (such as release paper, etc.) generated during the film pasting process need to be effectively collected and processed to keep the production environment clean and avoid material waste. The traditional collection method is to wind the residual film or waste materials on a fixed receiving column. As the production process progresses, the residual film or waste materials will continue to be wound, and the tightness of the residual film or waste materials will gradually increase, which increases the internal pressure of the residual film roll or waste roll, making it difficult to unwind.

The material collecting device 100 includes a support assembly 10, an adjustment assembly 20 connected to the support assembly 10, and a plurality of internal support mechanisms 30 connected to both the support assembly 10 and the adjustment assembly 20.

[0054] See also Figure 1 , Figure 2 and Figure 3The support assembly 10 includes a base 11, a support column 12 connected to the base 11, and a stop pin 13 inserted into the support column 12. A receiving groove 121 is provided in the support column 12. The receiving groove 121 extends along the radial direction of the support column 12. The opening of the receiving groove 121 faces the side of the support column 12 away from the base 11. The stop pin 13 is inserted into the support column 12 along a direction perpendicular to the radial direction of the support column 12 and passes through the receiving groove 121. In this embodiment, the base 11 is a disc-shaped structure, and the disc-shaped base 11 can provide stable support for the support column 12. The support column 12 is a columnar structure. In this embodiment, the support column 12 is a quadrangular prism. In other embodiments, the support column 12 can also be a triangular prism, a cylinder, etc. The stop pin 13 is a columnar structure. In this embodiment, two stop pins 13 are provided. The two stop pins 13 are located on the same horizontal plane and extend in parallel directions.

[0055] The support assembly 10 further includes a connection base 14, which is connected to the side of the base 11 away from the support column 12. In this embodiment, the connection base 14 is a columnar structure, and the connection base 14 is used to connect an external driving device (not shown), and the external driving device drives the base 11 and the support column 12 to rotate through the connection base 14.

[0056] See also Figures 1 to 4 The adjusting assembly 20 is connected to the supporting assembly 10. The adjusting assembly 20 includes an elastic member 21 disposed in the receiving groove 121, a limiting rod 22 slidably disposed in the receiving groove 121 and abutting against the elastic member 21, and a rotating member 23 connected to one end of the limiting rod 22 away from the elastic member 21. The limiting rod 22 is provided with a mutually connected clamping groove 221 and a avoiding groove 222 at one end abutting against the elastic member 21. The clamping groove 221 is arranged around the limiting rod 22, and the avoiding groove 222 is arranged on one side of the clamping groove 221 close to the elastic member 21. In this embodiment, the elastic member 21 is a spring, the limiting rod 22 is a cylindrical structure, the clamping groove 221 is an annular groove, and the width of the clamping groove 221 is greater than the diameter of the limiting pin 13, so that the clamping groove 221 can accommodate the limiting pin 13. There are two avoidance grooves 222, which are arranged in mirror symmetry, and both avoidance grooves 222 are connected to the clamping groove 221. The avoidance groove 222 includes a groove bottom 2221 connected to the clamping groove 221 and a groove wall 2222 away from the clamping groove 221. The distance between the groove bottoms 2221 of the two avoidance grooves 222 is less than the distance between the two limit pins 13. The rotating member 23 is a strip structure, and the extension direction of the rotating member 23 is perpendicular to the extension direction of the limit rod 22.

[0057] In this embodiment, the adjustment assembly 20 further includes a connecting pin 24 . The connecting pin 24 is a columnar structure, and two ends of the connecting pin 24 are fixedly connected to the limiting rod 22 and the rotating member 23 , respectively.

[0058] When the limiting rod 22 moves into the receiving groove 121, the rotating member 23 is pressed into the supporting column 12, and the rotating member 23 drives the limiting rod 22 to move into the receiving groove 121 through the connecting pin 24. The limiting rod 22 compresses the elastic member 21 until the clamping groove 221 corresponds to the limiting pin 13, and then the rotating member 23 is rotated 90° in the clockwise direction or counterclockwise direction, so that the limiting pin 13 is clamped in the clamping groove 221, thereby locking the limiting rod 22. When the limiting rod 22 moves out of the receiving groove 121, the rotating member 23 is rotated 90° in the clockwise direction or counterclockwise direction, so that the avoiding groove 222 corresponds to the limiting pin 13, and the elastic member 21 pushes the limiting rod 22 to move out of the receiving groove 121 until the limiting pin 13 abuts against the groove wall 2222 of the avoiding groove 222, and the limiting rod 22 is moved out of the receiving groove 121.

[0059] The internal support mechanism 30 is connected to the support assembly 10 and the adjustment assembly 20 respectively. The internal support mechanism 30 includes a traction member 31 arranged between the limit rod 22 and the rotating member 23, a plurality of connection components 32 connected to the traction member 31 and the support column 12, a plurality of internal support blocks 33 connected to the plurality of connection components 32 in a one-to-one correspondence, a plurality of clamping members 34 connected to the internal support blocks 33 in a one-to-one correspondence, and a plurality of support plates 35 connected to the internal support blocks 33 in a one-to-one correspondence. The plurality of connection components 32 are arranged around the support column 12.

[0060] See also Figure 1 and Figure 4 When the limit pin 13 is clamped in the clamping groove 221, the rotating member 23 pushes the traction member 31 to approach the support column 12, and the traction member 31 drives the multiple inner support blocks 33 away from the support column 12 through the multiple connecting components 32. The membrane 200 is wrapped around the multiple inner support blocks 33. Please refer to Figure 3 When the rotating member 23 drives the limiting rod 22 to rotate so that the limiting pin 13 abuts the avoiding groove 222, the limiting rod 22 pushes the traction member 31 away from the support column 12, and the traction member 31 drives the multiple inner support blocks 33 to approach the support column 12 through the multiple connecting components 32, so that the multiple inner support blocks 33 are separated from the membrane member 200.

[0061] See also Figure 1 and Figure 2 In this embodiment, the traction member 31 is a plate-like structure, so as to be connected with a plurality of connection components 32. A through hole 311 is provided on the traction member 31, which penetrates the traction member 31 in the up-down direction. The radius of the connecting pin 24 is smaller than the radius of the through hole 311. Thus, when the rotating member 23 drives the connecting pin 24 and the limiting rod 22 to rotate, the traction member 31 does not rotate with the connecting pin 24. When the rotating member 23 moves toward the support column 12, the rotating member 23 pushes the traction member 31 to move toward the support column 12. When the limiting rod 22 moves away from the receiving groove 121, the limiting rod 22 pushes the traction member 31 to move away from the support column 12.

[0062] In this embodiment, four connecting components 32 are provided, and the four connecting components 32 are respectively connected to the four side surfaces of the support column 12. In other embodiments, the support column 12 may be a triangular prism, in which case three connecting components 32 may be provided; in addition, the support column 12 may also be a cylinder, in which case five, six, etc. connecting components 32 may be provided. The specific shape of the support column 12 and the specific number of connecting components 32 are subject to actual needs and are not limited here.

[0063] The connecting assembly 32 includes a first connecting member 321 rotatably connected to the traction member 31, a second connecting member 322 rotatably connected to the support column 12, and a third connecting member 323 rotatably connected to the support column 12. The end of the first connecting member 321 away from the traction member 31 is rotatably connected to the middle part of the second connecting member 322, the end of the second connecting member 322 away from the support column 12 is rotatably connected to the inner support block 33, and the end of the third connecting member 323 away from the support column 12 is rotatably connected to the inner support block 33.

[0064] In this embodiment, the first connecting member 321 is a Y-shaped connecting rod, one end of the first connecting member 321 is rotatably connected to the traction member 31, so that the traction member 31 can drive the first connecting member 321 to move, and the other end of the first connecting member 321 is rotatably connected to the middle of the second connecting member 322. The second connecting member 322 is a sheet-like structure, one end of the second connecting member 322 is rotatably connected to the support column 12, and the other end of the second connecting member 322 is rotatably connected to the inner support block 33. In this way, when the traction member 31 moves away from the support column 12, the traction member 31 drives the first connecting member 321 to move upward, the first connecting member 321 drives the second connecting member 322 to rotate upward, and the second connecting member 322 drives the inner support block 33 to move toward the support column 12, that is, multiple inner support blocks 33 retract inwardly, so that multiple inner support blocks 33 are separated from the rolled film member 200. The third connecting member 323 is arranged below the second connecting member 322, the extension direction of the third connecting member 323 is parallel to the extension direction of the second connecting member 322, and the length of the third connecting member 323 is the same as the length of the second connecting member 322. The third connecting member 323 is a sheet-like structure, one end of the third connecting member 323 is rotatably connected to the support column 12, and the other end is rotatably connected to the inner support block 33. By providing the third connecting member 323, the stability of the inner support block 33 can be improved, and the membrane 200 can be easily wound around the inner support block 33, and the inner support block 33 can be easily separated from the membrane 200 when moving toward the support column 12.

[0065] In this embodiment, the inner support block 33 is a plate-like structure and the side away from the support column 12 is set as an arc surface 331, and when the limit pin 13 is clamped in the clamping groove 221, the center of the arc surface 331 is located on the axis of the receiving groove 121. When the limit pin 13 is clamped in the clamping groove 221, the multiple inner support blocks 33 are in an open state away from the support column 12, and the center of the arc surface 331 is located on the axis of the receiving groove 121. At this time, the multiple arc surfaces 331 are located on the same circle, so that the membrane 200 can be more easily wound on the multiple inner support blocks 33.

[0066] A material clamping groove 332 is provided on one side of the inner support block 33 away from the support column 12, and the extension direction of the material clamping groove 332 is parallel to the extension direction of the accommodating groove 121. The material clamping member 34 is slidably arranged in the material clamping groove 332, and the material clamping member 34 cooperates with the material clamping groove 332 to clamp the film head of the film member 200. In this embodiment, the material clamping member 34 is a columnar structure, and the structure of the material clamping groove 332 is adapted to the material clamping member 34. It can be understood that the radius of the material clamping member 34 is smaller than the radius of the material clamping groove 332. When in use, the material clamping member 34 is taken out of the material clamping groove 332, and then the film head of the film member 200 is placed in the material clamping groove 332, and then the material clamping member 34 is inserted into the material clamping groove 332, so that the material clamping member 34 cooperates with the material clamping groove 332 to clamp the film head of the film member 200, and then the film member 200 can be wound around a plurality of inner support blocks 33.

[0067] The cross section of the clamping groove 332 along the direction perpendicular to the extension direction of the clamping groove 332 is fan-shaped, and the angle range of the fan-shaped is 210°~270°. The angle of the fan-shaped can be 210°, 230°, 250°, 270°, etc., or any angle between 210°~270°, which is not limited here. When the angle of the fan-shaped is less than 210°, the clamping piece 34 is easy to detach from the opening of the clamping groove 332, resulting in the clamping piece 34 and the clamping groove 332 being unable to clamp the film head of the film 200. When the angle of the fan-shaped is greater than 270°, it is difficult to place the film head of the film 200 in the clamping groove 332. When the angle range of the fan-shaped is 210°~270°, it is convenient for the clamping piece 34 and the clamping groove 332 to clamp the film head of the film 200, and the clamping groove 332 can also clamp the clamping piece 34, and the clamping piece 34 is not easy to detach from the opening of the clamping groove 332.

[0068] A plurality of support plates 35 are respectively connected to the side of the inner support block 33 close to the base 11, and the support plates 35 protrude from the side of the inner support block 33 away from the support column 12 in the direction away from the support column 12. It can be understood that the support plates 35 correspond to the inner support block 33 one by one, and the support plates 35 are plate-shaped structures. By setting the support plates 35, the clamping member 34 can be supported to prevent the clamping member 34 from slipping from the clamping groove 332, and the film member 200 wound on the inner support block 33 can also be supported. It can be understood that the thicker the film member 200 is wound on the inner support block 33, the more likely it is that the outer layer of the film member 200 will tilt downward. By setting the support plates 35, the film member 200 can be supported in the vertical direction.

[0069] In this embodiment, the side of the inner support block 33 away from the support column 12 is set as a frosted surface. It can be understood that some membranes 200 have a sticky surface. When the sticky surface of the membrane 200 contacts the inner support block 33, it is easy to make the membrane 200 and the inner support block 33 stick together. By setting the side of the inner support block 33 away from the support column 12 as a frosted surface, it is easy to separate the membrane 200 from the inner support block 33.

[0070] The material receiving device 100 provided in the embodiment of the present application can support the adjustment component 20 and the inner support mechanism 30 through the support component 10, and can be connected to an external device so that the external device drives the material receiving device 100 to rotate, so as to collect the film 200. The connection component 32 and the inner support block 33 in the inner support mechanism 30 are arranged around the support column 12, so that a plurality of inner support blocks 33 can be used to wrap the film 200 to collect the film 200. The adjustment component 20 can drive the traction member 31 of the inner support mechanism 30 to move up and down, and then the traction member 31 drives the inner support block 33 to expand outward or retract inward through the connection component 32. The inner support block 33 is used to collect the film 200 when it is expanded outward, and can be separated from the collected film 200 when it is retracted inward, so that the film 200 can be removed from the inner support mechanism 30.

[0071] The working process of the material receiving device 100 provided in the embodiment of the present application is roughly as follows:

[0072] First, connect with the external driving device through the connecting seat 14, then press the rotating member 23 toward the support column 12, the rotating member 23 drives the limiting rod 22 to move into the accommodating groove 121 through the connecting pin 24, the limiting rod 22 compresses the elastic member 21 until the clamping groove 221 corresponds to the limiting pin 13, then rotate the rotating member 23 90° in the clockwise or counterclockwise direction, the limiting pin 13 is clamped in the clamping groove 221, and the position of the limiting rod 22 is locked. At this time, the rotating member 23 pushes the traction member 31 to move toward the support column 12, the traction member 31 rotates by pushing the second connection member 322 through the first connection member 321, and the second connection member 322 pushes the inner support block 33 away from the support column 12, so that the multiple inner support blocks 33 are in an open state.

[0073] Then, the clamping piece 34 on one of the inner support blocks 33 is removed from the clamping groove 332, the film head of the collected film 200 is placed in the clamping groove, and then the clamping piece 34 is installed in the clamping groove 332, so that the clamping piece 34 cooperates with the clamping groove 332 to clamp the film head of the film 200. Then, the external driving device drives the base 11 and the support column 12 to rotate through the connecting seat 14, so that the multiple inner support blocks 33 rotate around the support column 12, and then the film 200 can be collected.

[0074] When disassembling the film 200, the rotating member 23 is rotated 90° in the clockwise or counterclockwise direction, so that the avoidance groove 222 is opposite to the limit pin 13, and the elastic member 21 pushes the limit rod 22 to move outward from the accommodating groove 121 until the limit pin 13 abuts against the groove wall 2222 of the avoidance groove 222. At this time, the limit rod 22 pushes the traction member 31 away from the support column 12, and the traction member 31 drives the first connecting member 321 to move upward, and the first connecting member 321 pulls the second connecting member 322 to rotate upward, and the second connecting member 322 drives the inner support block 33 to move toward the support column 12, that is, multiple inner support blocks 33 retract inwardly, so that multiple inner support blocks 33 are separated from the rolled film 200, and then the rolled film 200 is taken out, and the film head of the film 200 is removed from the clamping member 34 and the clamping groove 332.
