Description

Technical Field

[0001] This utility model relates to the field of solar screen cutting technology, and in particular to a cutting device for solar screen production that is easy to position. Background Technology

[0002] Solar screen printing typically consists of a screen frame and a screen mesh. The screen frame holds the screen mesh in place, ensuring its stability during the printing process. The screen mesh supports and transfers the printing ink. During the production of solar screen printing, a screen cutting device is used to cut the screen mesh to a specific size before assembling it with the screen frame.

[0003] Typical mesh cutting devices simply convey and clamp the mesh using roller sets, and then directly cut the taut mesh with a cutting blade. However, this cutting method does not provide positioning for the mesh within the cutting area, which may result in curled edges at the cut, affecting subsequent mesh assembly. Utility Model Content

[0004] This utility model discloses a cutting device for solar screen production that facilitates positioning. It aims to solve the technical problem that ordinary cutting methods do not provide positioning for the mesh within the cutting range, which may cause the mesh to curl at the cut position, affecting the subsequent mesh assembly.

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

[0006] A cutting device for producing solar screens that is easy to position includes a first roller group, a second roller group, a linear guide rail and a sorting mechanism located between the first roller group and the second roller group, a lifting mechanism connected to one end of the linear guide rail, a limiting plate fixedly connected to the outer wall of the bottom end of the linear guide rail, a long strip-shaped slot through the limiting plate, a knife holder movably connected to the long strip-shaped slot, a cutting knife mounted on the knife holder, and a first extrusion pad attached to the bottom of the limiting plate.

[0007] The sorting mechanism includes a waist-shaped support, a spring disposed at the bottom end of the waist-shaped support, and a second compression pad attached to the top end of the waist-shaped support;

[0008] The first roller group and the second roller group are connected to side supports on both sides, and a connecting crossbar is fixedly connected between the two side supports on the same side. The connecting crossbar is connected to the lifting mechanism, the linear guide rail and the sorting mechanism respectively.

[0009] The system incorporates a waist-shaped support, a limiting plate, and a long, narrow groove. The first and second roller sets provide conveying and clamping for the net. When cutting is required, a spring provides pressure to the waist-shaped support, positioning the net at the cutting point. The long, narrow groove limits the cutting blade, ensuring its stable translation. Furthermore, the groove allows the limiting plate's pressing area to be as close as possible to the cutting point, preventing displacement and ensuring a stable cut.

[0010] In a preferred embodiment, the sorting mechanism further includes two drive slide rails, a roller frame, multiple rollers, a contact support plate, two inclined guide plates, and a second support housing disposed on the waist-shaped support.

[0011] Two drive slide rails are symmetrically arranged on the inner wall of the waist-shaped support, and each drive slide rail is movably connected to a slider. The roller frame is fixedly connected to one side of the outer wall of the slider, and multiple rollers are movably connected to the roller frame.

[0012] The two inclined guide plates are symmetrically fixedly connected to both ends of the contact support plate, and the second support shell is fixedly connected to the bottom end of the contact support plate. Connecting brackets are fixedly connected to the opposite sides of the second support shell, and the connecting brackets are connected to the connecting cross frame.

[0013] The top outer wall of the contact support plate is provided with multiple insertion holes, and the bottom outer wall of the waist-shaped support is fixedly connected with multiple insertion rods, and the multiple insertion rods are respectively inserted into the insertion holes.

[0014] The spring is wrapped around the outside of the insertion rod, and a circular support plate is fixedly connected to the bottom end of each insertion rod, and the bottom end of the spring is fixedly connected to the circular support plate.

[0015] With a sorting mechanism, before the waist-shaped support and the limiting plate clamp the net, the two roller frames move outward from the top initial position of the two drive slide rails. During the movement, the rollers contact the bottom of the net. By moving the rollers outward in opposite directions, the bottom of the net can be smoothed from the inside to the outside, further optimizing the flatness of the net cutting position.

[0016] In a preferred embodiment, the lifting mechanism includes a first support housing fixedly connected to one end of the linear guide rail, a first air rod disposed at the top of the first support housing, a second air rod disposed on one side of the first support housing, and a first support plate fixedly connected to the outer wall of the top of the tool holder.

[0017] A magnetic block is attached to the inner wall of the top of the first support housing, and a bottom limiting strip is fixedly connected to the inner wall of the bottom of the first support housing. An iron sheet is embedded in the inner wall of the top of the first support plate.

[0018] The iron sheet and the magnetic block attract each other, and the output end of the first gas rod passes through the first support shell and the magnetic block and abuts against the top of the iron sheet.

[0019] With a lifting mechanism, after one round of cutting, the cutting blade moves back to the first support housing along the linear guide. When the blade holder moves into the first support housing, the magnetic block quickly attracts the iron sheet, and at the same time, the blade holder is raised. Conversely, when using the cutting blade, it can be pushed out by the first air rod to disengage the magnetic block from the attracted iron sheet. Then, under the push of the second air rod, the first support plate and the blade holder can return to the linear guide. With this structure, pressing and cutting can be performed first, followed by horizontal cutting, thus avoiding curling at the cut when cutting directly horizontally.

[0020] As described above, a solar screen cutting device for easy positioning includes a first roller group, a second roller group, a linear guide rail and a sorting mechanism located between the first roller group and the second roller group, a lifting mechanism connected to one end of the linear guide rail, a limiting plate fixedly connected to the outer wall of the bottom end of the linear guide rail, a long strip-shaped slot penetrating the limiting plate, a knife holder movably connected to the long strip-shaped slot, a cutting knife mounted on the knife holder, and a first compression pad conforming to the bottom of the limiting plate; the sorting mechanism includes a waist-shaped support, a spring disposed at the bottom end of the waist-shaped support, and a second compression pad conforming to the top end of the waist-shaped support. The solar screen cutting device for easy positioning provided by this utility model has the technical effect of ensuring the stability of the cut through clamping and the limiting of the cutting knife.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] The present invention discloses a screen cutting device for solar screen production that is easy to position, which is mainly used in the production of solar screens.

[0028] Reference Figure 1 and Figure 2 A cutting device for solar screen production that is easy to position includes a first roller group 3, a second roller group 6, a linear guide rail 8 and a sorting mechanism 7 located between the first roller group 3 and the second roller group 6, a lifting mechanism 4 connected to one end of the linear guide rail 8, a limiting plate 11 fixedly connected to the outer wall of the bottom end of the linear guide rail 8, a long strip groove 12 that passes through the limiting plate 11, a knife holder 9 movably connected in the long strip groove 12, a cutting knife 10 installed on the knife holder 9, and a first extrusion pad 13 that is attached to the bottom of the limiting plate 11.

[0029] The sorting mechanism 7 includes a waist-shaped support 702, a spring 704 disposed at the bottom of the waist-shaped support 702, and a second compression pad 707 attached to the top of the waist-shaped support 702. The first roller group 3 and the second roller group 6 provide conveying and clamping effects for the net. When cutting is required, the spring 704 provides extrusion force to the waist-shaped support 702, and the first compression pad 13 and the second compression pad 707 strengthen the clamping force, thereby positioning the cutting position of the net. Based on the setting of the elongated through-slot 12, the cutting blade 10 can be limited, so that the cutting blade 10 always maintains stable translation. Furthermore, the setting of the elongated through-slot 12 allows the overall pressing area of ​​the limiting plate 11 to be as close as possible to the cutting point, which can better ensure that the cutting point of the net does not shift during the cutting process and ensure the stability of the cut.

[0030] Reference Figure 3 In a preferred embodiment, the first roller group 3 and the second roller group 6 are connected to side brackets 1 on both sides, and a connecting crossbeam 2 is fixedly connected between the two side brackets 1 on the same side. The connecting crossbeam 2 is connected to the lifting mechanism 4, the linear guide rail 8 and the sorting mechanism 7 respectively.

[0031] Reference Figure 3 In a preferred embodiment, the sorting mechanism 7 further includes two drive slide rails 701, roller frame 703, multiple rollers 709, contact support plate 714, two inclined guide plates 710, and a second support housing 712 disposed on the waist-shaped support 702.

[0032] Reference Figure 3 In a preferred embodiment, two drive slide rails 701 are symmetrically arranged on the inner wall of the waist-shaped support 702, and each drive slide rail 701 is movably connected to a slider 708. A roller frame 703 is fixedly connected to one side of the outer wall of the slider 708, and a plurality of rollers 709 are movably connected to the roller frame 703.

[0033] Reference Figure 3 In a preferred embodiment, two inclined guide plates 710 are symmetrically fixedly connected to both ends of the contact support plate 714, and the second support housing 712 is fixedly connected to the bottom end of the contact support plate 714. Connecting brackets 711 are fixedly connected to the opposite sides of the second support housing 712, and the connecting brackets 711 are connected to the connecting crossbeam 2.

[0034] Reference Figure 3 In a preferred embodiment, the top outer wall of the contact support plate 714 is provided with a plurality of insertion holes 713, and the bottom outer wall of the waist-shaped support 702 is fixedly connected with a plurality of insertion rods 706, and the plurality of insertion rods 706 are respectively inserted into the insertion holes 713.

[0035] Reference Figure 3 In a preferred embodiment, a spring 704 surrounds the insert rod 706, and a circular support plate 705 is fixedly connected to the bottom end of each insert rod 706. The bottom end of the spring 704 is fixedly connected to the circular support plate 705. Before the waist-shaped support 702 and the limiting plate 11 clamp the net, the two roller frames 703 move outward from the initial position at the top of the two drive slide rails 701. During the movement, the rollers 709 contact the bottom of the net. By moving the rollers 709 outward in opposite directions, the bottom of the net can be smoothed from the inside to the outside. At the same time, when the roller frames 703 move to the bottom end of the waist-shaped support 702, they contact the inclined guide plate 710 until they move to the top of the support plate 714, which can lift the waist-shaped support 702 to clamp the net. Under this structure, the flatness of the net cutting position can be further optimized.

[0036] Reference Figure 4 In a preferred embodiment, the lifting mechanism 4 includes a first support housing 402 fixedly connected to one end of the linear guide rail 8, a first air rod 401 disposed at the top of the first support housing 402, a second air rod 407 disposed on one side of the first support housing 402, and a first support plate 406 fixedly connected to the outer wall of the top of the tool holder 9.

[0037] Reference Figure 4 In a preferred embodiment, a magnetic block 403 is attached to the inner wall of the top end of the first support housing 402, and a bottom limiting strip 404 is fixedly connected to the inner wall of the bottom end of the first support housing 402. An iron sheet 405 is embedded in the inner wall of the top end of the first support plate 406.

[0038] Reference Figure 4 In a preferred embodiment, the iron sheet 405 and the magnetic block 403 attract each other, and the output end of the first air rod 401 passes through the first support housing 402 and the magnetic block 403 simultaneously, abutting against the top of the iron sheet 405. After one round of cutting, the cutting blade 10 moves back along the linear guide 8 into the first support housing 402. Since the first support housing 402 is higher than the linear guide 8, when the blade holder 9 moves into the first support housing 402, the magnetic block 403... 3. Quickly adsorb the iron sheet 405 and simultaneously raise the knife holder 9 so that the knife holder 9 is retracted into the limiting plate 11. Conversely, when using the cutting knife 10, it can be pushed out first by the first air rod 401 so that the magnetic block 403 is separated from the adsorbed iron sheet 405. Then, under the push of the second air rod 407, the first support plate 406 and the knife holder 9 can return to the linear guide rail 8. Under this structure, it is possible to first press and cut, and then move and cut laterally, thereby avoiding the curling of the cut edge when cutting directly laterally.

[0039] Working principle: The first roller group 3 and the second roller group 6 provide conveying and clamping effects for the net. When cutting is required, the spring 704 provides extrusion force to the waist-shaped support 702, and the first extrusion pad 13 and the second extrusion pad 707 strengthen the clamping force, which can provide positioning for the cutting position of the net. Based on the setting of the elongated through groove 12, the cutting blade 10 can be limited, so that the cutting blade 10 can always maintain stable translation. In addition, the setting of the elongated through groove 12 can make the overall pressing area of ​​the limiting plate 11 as close as possible to the cutting point, which can better ensure that the cutting point of the net will not be displaced during the cutting process and ensure the stability of the cut.

[0040] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
