Description

Technical Field

[0001] This invention relates to the field of cutting device technology, specifically to a cutting device for wallpaper sales with multiple limiting mechanisms. Background Technology

[0002] In the wallpaper sales process, it is usually necessary to cut the whole roll of wallpaper into single samples or supply sections of corresponding length according to the actual wall size of the customer, so as to meet the installation needs of different wall sizes.

[0003] According to CN220882591U, a cutting device for decorative paper is disclosed. This technology discloses a technical solution that includes "using a mechanism that drives a pressure plate with a thread to specifically press the part to be cut, so that the cutting is stable and will not cause errors such as deviation. The sliding connection mechanism between the support plate and the limiting groove in the device allows the cutting position of the decorative paper to be adjusted. At the same time, the sliding relationship between the support plate and the limiting channel is used to strongly fix the part to be cut, so as to facilitate cutting with cutting scissors. Furthermore, the device uses a squeezing plate that slides in the front and rear symmetrical squeezing grooves to control the clamping work of the decorative paper before cutting by rotating the adjustment knob."

[0004] In the wallpaper sales process, operators need to frequently change the rolls to accommodate different customers' requirements for wall height and pattern display. However, the rolls in existing cutting equipment are usually fixed axially by bolt locking or special clamps. This type of fixing structure requires each bolt to be tightened or the clamp to be operated during each disassembly and assembly, which makes the roll changing process cumbersome and time-consuming. Especially during the peak sales season when multiple wallpaper patterns need to be processed continuously, the frequent disassembly and assembly operations seriously reduce the continuity and overall efficiency of the cutting operation. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a wallpaper cutting device with multiple limiting mechanisms. The disassembly and installation of the roll does not require any external tools. Compared with existing technologies that require the removal of bolts or the use of special clamps, the operation is simpler and faster, effectively improving the efficiency of roll changing when frequently changing wallpaper patterns.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wallpaper cutting device with multiple limiting mechanisms, comprising a cutting table, wherein a cutting mechanism is provided on the cutting table for cutting wallpaper, and the cutting mechanism includes:

[0007] The limiting components include left and right uprights fixed to the rear end of the top of the cutting table;

[0008] The mounting components include a cylindrical shell that is horizontally fixed inside the stand, an inner rod that is installed through the inside of the cylindrical shell, a conical head that is rotatably installed at the inner end of the inner rod, a handwheel that is fixed at the outer end of the inner rod, a spring that is installed inside the cylindrical shell and sleeved on the outside of the inner rod, a protruding rod that is fixed at the upper end of the inner rod, a long hole and a short hole that are connected to each other at the upper end of the cylindrical shell, and a drum that is inserted between the conical heads on the left and right sides.

[0009] The main components include a gantry frame fixed to the front end of the top of the cutting table, with a sliding plate horizontally mounted on the front end of the gantry frame;

[0010] The execution component is set on the main component and is used for cutting infeed and feeding.

[0011] Preferably, the limiting component further includes a shaft seat that is vertically slidably installed inside the upper part of the stand, a first cylinder is installed on the top of the stand for controlling the lifting and lowering of the shaft seat, and a pressure roller is rotatably installed between the left and right shaft seats.

[0012] Preferably, the main component further includes synchronous pulleys rotatably installed at the left and right ends inside the gantry frame, a synchronous belt is installed between the left and right synchronous pulleys, a reduction motor is installed at the rear end of the gantry frame to control the rotation of one of the synchronous pulleys, and the slide plate is fixed to the synchronous belt by a connector.

[0013] Preferably, the main component further includes second cylinders installed on the left and right sides of the rear end of the gantry frame, and pressure bars are fixed between the output ends of the second cylinders on the left and right sides.

[0014] Preferably, the execution component includes a shaft plate fixed to the front end of the slide plate, a turntable rotatably mounted on the front end of the shaft plate, an extension frame fixed to the outer wall of the turntable, a blade fixed to the lower end of the extension frame, and a third cylinder pivotally connected to the upper side of the front end of the shaft plate, and the output end of the third cylinder is pivotally connected to the extension frame.

[0015] Preferably, the surface of the pressure roller is covered with a dust-adhesive rubber layer, and the dust-adhesive rubber layer is made of adhesive silicone. Beneficial effects

[0016] This invention provides a wallpaper cutting device with multiple limiting mechanisms. Compared with the prior art, it has the following advantages:

[0017] 1. By using the combination of the conical head and the spring, the disassembly and installation of the roll can be carried out without the aid of any external tools. Pulling the handwheel moves the conical head outward to detach it from the paper core. Rotating the handwheel allows the protruding rod to engage with the short hole to maintain the detached state. When operating in reverse, the spring releases its elastic force to push the conical head to automatically insert into the paper core to achieve axial locking. Compared with the existing technology that requires the removal of bolts or the use of special clamps, the operation is simpler and faster, effectively improving the roll changing efficiency when frequently changing wallpaper patterns.

[0018] 2. The first cylinder drives the pressure roller to always press against the surface of the roll. As the diameter of the roll gradually decreases, the first cylinder pushes the pressure roller to move downwards to maintain the contact state. This keeps the wallpaper flat throughout the unrolling process and generates friction to prevent the roll from rotating due to inertia. At the same time, the adhesive silicone material layer on the surface of the pressure roller is in direct contact with the wallpaper surface and adheres to the dust, preventing dust from being pressed into the wallpaper surface or edge sealant during subsequent cutting or laying. This ensures the cleanliness of the wallpaper surface and the accuracy of the cutting dimensions. Attached Figure Description

[0025] 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.

[0026] Please see Figure 1 - Figure 5This invention provides a technical solution: a wallpaper cutting device with multiple limiting mechanisms, including a cutting table 1, a cutting mechanism 2 on the cutting table 1 for cutting wallpaper, and the cutting mechanism 2 including:

[0027] The limiting component 21 includes left and right uprights 211 fixed to the top rear end of the cutting table 1;

[0028] The mounting assembly 22 includes a cylindrical shell 221 that is horizontally fixed inside the stand 211. An inner rod 222 is installed inside the cylindrical shell 221. A conical head 223 is rotatably installed at the inner end of the inner rod 222. A handwheel 224 is fixed at the outer end of the inner rod 222. A spring 225 is installed inside the cylindrical shell 221 and sleeved on the outside of the inner rod 222. A protruding rod 226 is fixed at the upper end of the inner rod 222. A long hole 227 and a short hole 228 are opened at the upper end of the cylindrical shell 221, and the long hole 227 and the short hole 228 are connected. A drum 25 is inserted and installed between the conical heads 223 on the left and right sides.

[0029] The main component 23 includes a gantry frame 231 fixed to the front end of the top of the cutting table 1, and a sliding plate 235 is horizontally slidably installed at the front end of the gantry frame 231;

[0030] The execution component 24 is mounted on the main component 23 and is used for cutting infeed and feeding lifting.

[0031] In this embodiment, when disassembling the roll 25, pulling the handwheel 224 causes the conical head 223 on the inner rod 222 to move outward, and the conical head 223 disengages from the paper core at the end of the roll 25. At the same time, the protruding rod 226 on the inner rod 222 slides from the end of the long hole 227 away from the short hole 228 into the connection between the long hole 227 and the short hole 228. Then, rotating the handwheel 224 causes the protruding rod 226 on the inner rod 222 to slide from the connection into the short hole 228, so that the conical head 223 remains in the disengaged state.

[0032] When installing the roll 25, rotating the handwheel 224 causes the protruding rod 226 on the inner rod 222 to rotate out from the short hole 228 to the connection between the long hole 227 and the short hole 228. At this time, the spring 225 releases the elastic force to push the protruding rod 226 on the inner rod 222 to slide from the connection into the long hole 227. At the same time, the conical head 223 on the inner rod 222 is inserted into the paper core at the end of the roll 25 and achieves axial locking.

[0033] The disassembly and installation of the roll 25 can be carried out without the aid of any external tools. Compared with the existing technology that requires the removal of bolts or the use of special clamps, the operation is simpler and faster, and the efficiency of roll changing when frequently changing wallpaper patterns is effectively improved.

[0034] Specifically, the limiting component 21 also includes a shaft seat 212 that is vertically slidably installed inside the upper end of the stand 211. A first cylinder 213 is installed on the top of the stand 211 and is used to control the lifting and lowering of the shaft seat 212. A pressure roller 214 is rotatably installed between the left and right shaft seats 212.

[0035] In this embodiment, the first cylinder 213 drives the shaft seat 212 to raise and lower the pressure roller 214, so that the pressure roller 214 is always pressed against the surface of the roll 25. When the diameter of the roll 25 gradually decreases, the first cylinder 213 pushes the pressure roller 214 to move down accordingly, maintaining the contact state. The pressure roller 214 flattens the wallpaper and generates friction to prevent the roll 25 from rotating due to inertia; ensuring that the wallpaper is flat throughout the unwinding process and ensuring the accuracy of the cutting size.

[0036] Specifically, the main component 23 also includes synchronous pulleys 232 rotatably installed at the left and right ends inside the gantry frame 231, a synchronous belt 233 is installed between the left and right synchronous pulleys 232, a geared motor 234 is installed at the rear end of the gantry frame 231 and used to control the rotation of one of the synchronous pulleys 232, and the slide plate 235 is fixed to the synchronous belt 233 through the connector 236.

[0037] In this embodiment, the geared motor 234 drives one of the synchronous pulleys 232 to rotate. The synchronous pulley 232 drives the other synchronous pulley 232 to rotate synchronously through the synchronous belt 233. During the rotation, the synchronous belt 233 drives the slide plate 235 to slide horizontally along the front end of the gantry frame 231 through the connector 236. When the slide plate 235 slides, it drives the execution component 24 to move synchronously. The blade 244 on the execution component 24 then sweeps horizontally across the wallpaper surface to complete the cutting.

[0038] Specifically, the main component 23 also includes second cylinders 237 installed on the left and right sides of the rear end of the gantry 231, and pressure bars 238 are fixed between the output ends of the second cylinders 237 on the left and right sides.

[0039] In this embodiment, the second cylinder 237 drives the pressure strip 238 to rise and fall by extending and retracting its piston rod. When the execution component 24 is cutting, the second cylinder 237 pushes the pressure strip 238 down and presses the wallpaper tightly onto the cutting table 1, so that the wallpaper remains taut and flat in the cutting area. After the cutting is completed, the second cylinder 237 drives the pressure strip 238 up and releases the wallpaper.

[0040] Specifically, the execution component 24 includes a shaft plate 241 fixed to the front end of the slide plate 235, a turntable 242 rotatably mounted on the front end of the shaft plate 241, an extension frame 243 fixed to the outer wall of the turntable 242, a blade 244 fixed to the lower end of the extension frame 243, and a third cylinder 245 pivotally connected to the upper side of the front end of the shaft plate 241, and the output end of the third cylinder 245 is pivotally connected to the extension frame 243.

[0041] In this embodiment, the third cylinder 245 drives the extension frame 243 to rotate the turntable 242 around the shaft plate 241 by extending and retracting its piston rod. When the extension frame 243 rotates, it drives the blade 244 to rise and fall. When cutting, the blade 244 descends to cut into the wallpaper. After cutting, the blade 244 rises and detaches from the wallpaper.

[0042] Specifically, the surface of the pressure roller 214 is covered with a dust-adhesive rubber layer, and the dust-adhesive rubber layer is made of adhesive silicone.

[0043] In this embodiment, the pressure roller 214 presses against the wallpaper surface on the roll 25. When the roll 25 is unwound, the adhesive silicone material layer covering the surface of the pressure roller 214 comes into direct contact with the wallpaper surface and adheres to the dust. The Shore A hardness of the adhesive silicone material layer is 30 to 50 degrees, and the adhesion is 300gf / 20mm to 500gf / 20mm, which ensures the dust-adhesive effect while avoiding adhesive residue or damage to the wallpaper texture.

[0044] The working principle and usage process of this invention are as follows: First, when disassembling the roll 25, pull the handwheel 224 to move the conical head 223 on the inner rod 222 outward. The conical head 223 disengages from the paper core at the end of the roll 25. At the same time, the protruding rod 226 on the inner rod 222 slides from the end of the long hole 227 away from the short hole 228 into the communication between the long hole 227 and the short hole 228. Then, rotate the handwheel 224 to move the protruding rod 226 on the inner rod 222 from the communication into... The short hole 228 keeps the conical head 223 in the disengaged state. When installing the roll 25, rotating the handwheel 224 drives the protruding rod 226 on the inner rod 222 to rotate out from the short hole 228 to the connection between the long hole 227 and the short hole 228. The spring 225 releases its elastic force to push the protruding rod 226 on the inner rod 222 to slide into the long hole 227 from the connection. At the same time, the conical head 223 on the inner rod 222 inserts into the paper core at the end of the roll 25 and achieves axial locking.

[0045] The first cylinder 213 drives the shaft seat 212 to raise and lower the pressure roller 214, so that the pressure roller 214 is always pressed against the surface of the drum 25. When the diameter of the drum 25 gradually decreases, the first cylinder 213 pushes the pressure roller 214 to move down accordingly, maintaining the contact state.

[0046] When the roll 25 is unwound, the adhesive silicone material layer on the surface of the pressure roller 214 comes into direct contact with the wallpaper surface and adheres to the dust.

[0047] The geared motor 234 drives one of the synchronous pulleys 232 to rotate. The synchronous pulley 232 drives the other synchronous pulley 232 to rotate synchronously through the synchronous belt 233. During the rotation, the synchronous belt 233 drives the slide plate 235 to slide horizontally along the front end of the gantry frame 231 to the cutting station through the connector 236.

[0048] The second cylinder 237 pushes the pressing strip 238 down and presses the wallpaper tightly against the cutting table 1 surface;

[0049] The third cylinder 245 drives the extension frame 243 to rotate the turntable 242 around the shaft plate 241, and the blade 244 descends to cut into the wallpaper; the slide plate 235 slides to drive the blade 244 on the execution component 24 to sweep across the wallpaper surface laterally to complete the cutting.

[0050] After cutting, the third cylinder 245 drives the blade 244 to rise and detach from the wallpaper, while the second cylinder 237 drives the pressure strip 238 to rise and release the wallpaper.
