Description

Technical Field

[0001] This application belongs to the field of sheet metal production technology, specifically relating to a protective film waste edge collection mechanism. Background Technology

[0002] During the production of sheet materials, manufacturers typically cover the surface with a protective film to prevent dust accumulation and scratches. Normally, the protective film is wider than the sheet material to facilitate the lamination process; however, in this case, the protective film extends significantly beyond the sheet, affecting subsequent packaging steps. Therefore, it is necessary to separate and recycle the waste edges of the protective film. In existing technologies, the separation and recycling of waste edges of the protective film is generally referred to as the waste edge collection operation.

[0003] In the prior art, the step of collecting the waste edge of the protective film is achieved by a cutting tool; specifically, the cutting tool is fixedly set on the upper side of the board, and the blade cuts downward into the waste edge of the protective film; at the same time, the board is powered by a belt drive structure or other mechanical components to move horizontally, so that the waste edge of the protective film is separated under the action of the cutting edge of the cutting tool.

[0004] The inventors discovered that after the waste edges of the protective film are separated, they usually hang down to the ground naturally or are stored in a recycling bin placed on the ground. However, because the protective film usually has a certain degree of rigidity and is difficult to bend, there are unexpected situations where the waste edges of the protective film occupy excessive ground space or extend into the outer area of ​​the recycling bin, affecting the on-site working environment and causing difficulties for the subsequent sorting steps. Utility Model Content

[0018] In one possible implementation, the adjustment structure includes:

[0019] A fixing screw is fixedly connected to the cutting member, and its axis is parallel to the main shaft; and

[0020] The translational nut is threaded onto the fixed screw and is detachably connected to the support plate.

[0021] In one possible implementation, the reel further includes:

[0022] Two bushings are respectively disposed on both sides of the corresponding cutting member along the axial direction of the main shaft, and both are slidably sleeved on the main shaft; and each bushing has a connecting arm extending outward along its radial direction.

[0023] The two ends of the take-up shaft are rotatably connected to the extension ends of the two connecting arms, and the rotation drive component is a rotary motor fixedly mounted on one of the connecting arms and drivenly connected to the take-up shaft.

[0024] In one possible implementation, the outer peripheral wall of the spindle has a strip groove extending along its axial direction, and each bushing has a protrusion on its inner peripheral surface suitable for embedding in the strip groove;

[0025] Each of the protrusions has a concave ball groove on its embedded surface, and a ball is embedded in the concave ball groove, with the ball in contact with the bottom of the strip groove.

[0026] In one possible implementation, the cutting member includes:

[0027] A positioning sleeve, which is slidably mounted on the main shaft; and

[0028] The cutting tool is fixedly connected to the positioning sleeve and is used to insert downward into the waste edge of the protective film to cut off the waste edge of the protective film;

[0029] The positioning sleeve is fixedly connected to a fixing nut that communicates with the strip groove, and the fixing nut is threadedly connected to a locking bolt that is suitable for embedding into the strip groove and abutting against the bottom of the strip groove.

[0030] In one possible implementation, the reciprocating drive component includes:

[0031] A translational plate, slidably disposed on the outer side of the main shaft along its axial direction, and drivingly connected to the four bushings, such that each bushing is adapted to move synchronously with the translational plate; and

[0032] A rotating motor is fixedly mounted on the outside of the main shaft. Its power output axis is parallel to the vertical direction, and its power output end has a turntable extending radially outward. The turntable has a transmission arm that is rotatably connected to it in the vertical direction, and the swing end of the transmission arm is hinged to one end of the translation plate in the vertical direction.

[0033] When the rotating motor is started, the turntable rotates, which drives the transmission arm to move around the central axis of the turntable, and drives the translation plate to move back and forth.

[0034] In one possible implementation, each of the bushings has a connecting nut on its outer circumferential surface;

[0035] The translation plate has four sets of through holes corresponding to the four bushings. Each set of through holes includes multiple through holes spaced apart along the axial direction of the main shaft, and each through hole is adapted to be coaxially arranged with the connecting nut.

[0040] In this embodiment, the positions of the two sets of cutting components can be fixed by the main shaft, allowing the cutting components to act on the protective film waste edges extending from both sides of the sheet metal, thus cutting off the protective film waste edges at the positions of the cutting components. Based on this, a retaining member can constrain the cut-off protective film waste edges to prevent bending between the retaining member and the cutting components, thereby ensuring the stability of the protective film waste edge cutting process. Simultaneously, by connecting the end of the protective film waste edge to the outer circumferential surface of the winding shaft, the winding shaft can be rotated by a rotation drive member, winding the cut-off protective film waste edges onto the winding shaft to achieve collection. During the collection process, a reciprocating drive member drives the two winding shafts to reciprocate along the axial direction of the main shaft, changing the winding area of ​​the protective film waste edges, allowing the winding shafts to wind more protective film waste edges, ensuring the stability of the protective film waste edge collection process.

[0041] The protective film waste edge collection mechanism provided in this embodiment, compared with the prior art, can simultaneously cut off the waste edge of the protective film through the cutting component and recycle the cut waste edge through the winding shaft, thereby avoiding the technical problem of the protective film waste edge occupying the on-site working environment and affecting the stability of the board production process.

Therefore, they should not be construed as limitations on this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0060] Please refer to the following: Figures 1 to 12 The waste edge collection mechanism for protective film provided in this application will now be described. The waste edge collection mechanism for protective film proposed in this application includes a main shaft 1, two sets of cutting components 2, and two sets of recycling components.

[0061] The main shaft 1 is fixedly mounted above the moving area of ​​the plate by means of a mechanical structure, and its axis is parallel to the width direction of the plate, so that its two ends extend to both sides of the plate and pass through the outer edge of the waste edge of the protective film on the plate.

[0062] Two sets of cutting components 2 are arranged side by side on the main shaft 1 along the axial direction of the main shaft 1, and are used to cut off the protective film waste edges protruding from both sides of the plate respectively. In this embodiment, the relative position of the cutting components 2 and the main shaft 1 can be adjusted and locked to achieve the cutting off of protective film waste edges with different width requirements.

[0063] The two sets of recycling components correspond to the two sets of cutting components 2. In this embodiment, each set of recycling components includes a binding element 3 and a winding shaft 4.

[0064] The positioning member 3 is fixedly installed on the corresponding cutting member 2 and is used to connect with the waste edge of the protective film after it is cut off by the cutting member 2. This restricts the bending of the waste edge of the protective film between the positioning member 3 and the cutting member 2, avoids the pulling phenomenon, and ensures the stability of the cutting member 2 in the process of cutting the waste edge of the protective film.

[0065] The take-up shaft 4 is positioned on the upper side of the tie-in member 3 and is parallel to the main shaft 1. In actual use, the outer circumferential surface of the take-up shaft 4 can contact the waste edge of the protective film (by adhesive or mechanical means) so that when the take-up shaft 4 rotates, the waste edge of the protective film is wound around the outer circumference of the take-up shaft 4. Furthermore, the take-up shaft 4 is driven by a rotation drive member 41 for rotating it about its own central axis.

[0066] The main shaft 1 also has a reciprocating drive component 5 connected to the two take-up shafts 4. The reciprocating drive component 5 can drive the two take-up shafts 4 to reciprocate synchronously, and the direction of movement is parallel to the main shaft 1.

[0067] In this embodiment, the positions of the two sets of cutting components 2 can be fixed by the main shaft 1, so that the cutting components 2 can act on the protective film waste edges extending from both sides of the board, thereby cutting off the protective film waste edges at the positions of the cutting components 2. Based on this, the cut-off protective film waste edges can be constrained by the binding member 3 to prevent the protective film waste edges between the binding member 3 and the cutting component 2 from bending, thus ensuring the stability of the protective film waste edge cutting process. At the same time, by connecting the end of the protective film waste edge to the outer peripheral surface of the winding shaft 4, the cut-off protective film waste edges can be wound onto the winding shaft 4 by rotating the drive member 41, thereby realizing the collection of the protective film waste edges. During the collection of protective film waste edges, the reciprocating drive member 5 drives the two winding shafts 4 to move back and forth along the axial direction of the main shaft 1, thereby changing the winding area of ​​the protective film waste edges, so that the winding shafts 4 can wind more protective film waste edges, ensuring the stability of the protective film waste edge collection process.

[0068] The protective film waste edge collection mechanism provided in this embodiment, compared with the prior art, can simultaneously cut off the waste edge of the protective film through the cutting component 2 and recycle the cut waste edge through the winding shaft 4, thereby avoiding the technical problem of the protective film waste edge occupying the on-site working environment and affecting the stability of the board production process.

[0069] In some embodiments, such as Figure 2 , Figure 6 and Figure 7 As shown, the clamping member 3 includes a support plate 31 and two clamping plates 32.

[0070] The support plate 31 is disposed on the side of the corresponding cutting member 2 facing away from the other cutting member 2, and is connected to the corresponding cutting member 2 by means of the adjusting structure 6, so as to move relative to the cutting member 2 in an axial direction suitable for the main shaft 1, and fix the support plate 31 directly above the outer side of the waste edge of the plate and the protective film.

[0071] Two clamping plates 32 are arranged side by side on the support plate 31 in the vertical direction and are used to abut against the upper and lower sides of the waste edge of the protective film, thereby restricting the waste edge of the protective film from moving axially along the main shaft 1 under the action of the traction force of the winding shaft 4.

[0072] In some embodiments, such as Figure 7 As shown, each of the two clamping plates 32 has multiple protrusions 321 on its adjacent sides. The multiple protrusions 321 are spaced apart along the axial direction of the main shaft 1, and each protrusion 321 is made of elastic material to abut against the waste edge of the protective film and generate elastic deformation, thereby preventing the waste edge of the protective film from leaving the space between the two clamping plates 32 under the action of the traction force generated by the reciprocating movement of the winding shaft 4.

[0073] Furthermore, since the arrangement direction of the protruding teeth 321 is along the axial direction of the main shaft 1, it will not damage the waste edge of the protective film, thereby avoiding the situation where the waste edge of the protective film breaks due to friction.

[0074] In some embodiments, such as Figure 6 As shown, the adjustable distance structure 6 includes a fixed screw 61 and a translational nut 62.

[0075] The fixing screw 61 is fixedly connected to the cutting component 2, and its axis is parallel to the main shaft 1.

[0076] The translation nut 62 is threaded onto the fixed screw 61 and is detachably connected to the support plate 31.

[0077] In practical use, when it is necessary to adjust the horizontal distance between the cutting component 2 and the support plate 31, the translation nut 62 and the support plate 31 can be removed first, and then the translation nut 62 can be rotated; when the required distance is reached, the translation nut 62 and the support plate 31 can be reassembled to complete the adjustment of the distance.

[0078] It should be further noted that, in this embodiment, as Figure 8 As shown, the support plate 31 has a reserved hole suitable for the fixing screw 61 to pass through, and a plurality of mounting holes spaced around the reserved hole.

[0079] Based on the foregoing, the translational nut 62 has multiple connecting rods that are adapted to pass through multiple mounting holes and extend out, and the extended end of each connecting rod has an elastic block adapted to abut against the support plate 31 to limit the connecting rod from disengaging from the mounting hole, the support plate 31 and the fixing screw 61 from separating.

[0080] In some embodiments, such as Figure 3 As shown, the winding shaft 4 also includes two bushings 7, which are respectively arranged on both sides of the corresponding cutting member 2 along the axial direction of the main shaft 1, and are slidably sleeved on the main shaft 1.

[0081] In this embodiment, each bushing 7 has a connecting arm 71 extending radially outward; based on this, the two ends of the take-up shaft 4 are rotatably connected to the extension ends of the two connecting arms 71 respectively, and the aforementioned rotation drive member 41 is a rotation motor fixedly mounted on one of the connecting arms 71 and drivenly connected to the take-up shaft 4.

[0082] In some embodiments, such as Figure 4 , Figure 9 , Figure 11 and Figure 12 As shown, the outer peripheral wall of the main shaft 1 has a strip groove 11 extending along its axial direction, and each bushing 7 has a protrusion 72 on its inner peripheral surface that is suitable for embedding in the strip groove 11, so as to limit the rotation of the bushing 7 relative to the main shaft 1 and limit the movement trajectory of the bushing 7 relative to the main shaft 1.

[0083] Each of the protrusions 72 has a concave ball groove 721 on its embedded surface, and a ball 722 is embedded in the concave ball groove 721. The ball 722 is connected to the bottom of the strip groove 11 to ensure the smooth movement of the bushing 7.

[0084] In some embodiments, such as Figure 6 As shown, the cutting component 2 includes a positioning sleeve 21 and a cutting tool 22.

[0085] The positioning sleeve 21 is fitted onto the spindle 1, and the positioning sleeve 21 is adapted to move relative to the spindle 1 along the axial direction of the spindle 1.

[0086] The cutting tool 22 is fixedly connected to the positioning sleeve 21 and is used to insert downward into the waste edge of the protective film and coincide with the movement trajectory of the waste edge of the protective film to cut off the waste edge of the protective film.

[0087] In order to fix the moving position of the positioning sleeve 21, a fixing nut 211 communicating with the strip groove 11 is fixedly connected to the positioning sleeve 21. Specifically, the positioning sleeve 21 has a hole that runs through it radially. The fixing nut 211 is fixedly connected to the outer circumferential surface of the positioning sleeve 21 and communicates with this hole. Based on this, a locking bolt 212 suitable for embedding into the strip groove 11 and abutting the bottom of the strip groove 11 is threaded onto the fixing nut 211.

[0088] In practical use, by embedding the locking bolt 212 into the strip groove 11, the rotation of the positioning sleeve 21 relative to the main shaft 1 with its own central axis as the axis can be restricted; at the same time, by abutting the bottom of the strip groove 11 with the locking bolt 212, the friction between the end of the locking bolt 212 and the bottom of the strip groove 11 can be used to restrict the movement of the positioning sleeve 21 along the axial direction of the main shaft 1.

[0089] In some embodiments, such as Figure 1 and Figure 5 As shown, the reciprocating drive component 5 includes a translation plate 51 and a rotary motor 52.

[0090] The translation plate 51 is slidably disposed on the outside of the main shaft 1 along the axial direction of the main shaft 1, specifically on the upper side of the main shaft 1. The translation plate 51 is connected to four bushings 7 in a transmission manner so that each bushing 7 is adapted to move synchronously with the translation plate 51.

[0091] The rotating motor 52 is fixedly installed on the outside of the main shaft 1. Its power output axis is parallel to the vertical direction, and its power output end has a turntable 521 extending outward along its radial direction.

[0092] The turntable 521 has a transmission arm 522 that is rotatably connected to it in the vertical direction, and the axis of connection between the transmission arm 522 and the turntable 521 is located outside the central axis of the turntable 521. Furthermore, the swing end of the transmission arm 522 is hinged to one end of the translation plate 51 in the vertical direction.

[0093] By adopting the above technical solution, when the rotating motor 52 is started, the turntable 521 can rotate around its central axis, thereby driving the transmission arm 522 to move around the central axis of the turntable 521 and driving the translation plate 51 to move back and forth.

[0094] In some embodiments, such as Figure 1 , Figure 5 and Figure 9 As shown, each bushing 7 has a connecting nut 73 on its outer circumferential surface.

[0095] The translation plate 51 has four sets of through holes 511 corresponding to the four bushings 7. Each set of through holes 511 includes multiple through holes 511 spaced apart along the axial direction of the main shaft 1. As the bushings 7 move relative to the translation plate 51, each through hole 511 is adapted to be coaxially arranged with the connecting nut 73.

[0096] In this embodiment, each bushing 7 also includes a stop bolt 74, which is adapted to pass through the through hole 511 and be threadedly connected to the corresponding connecting nut 73 so as to drive the bushing 7 and the translation plate 51.

[0097] It should be noted that, in order to ensure the stability of the combination of the retaining bolt 74 and the connecting nut 73, a recessed groove communicating with the center hole of the connecting nut 73 is usually provided on the outer circumferential surface of the bushing 7. This recessed groove allows the end of the retaining bolt 74 to be inserted to ensure that the retaining bolt 74 passes through the connecting nut 73.

[0098] In some embodiments, such as Figure 1 and Figure 4 As shown, the main spindle 1 also includes two side plates 8.

[0099] Two side plates 8 are fixedly connected to both ends of the main shaft 1, and the two side plates 8 are connected by a base plate 9. In actual installation, the base plate 9 is used to fix the main shaft 1 to the surrounding mechanical equipment so as to fix the main shaft 1 above the plate transport area.

[0100] Based on the foregoing, the translation plate 51 is slidably connected to the two side plates 8, and the rotation motor 52 is fixedly installed on the outer side of one of the side plates 8.

[0101] The above content is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
