Description

Technical Field

[0001] This application relates to the technical field of laundry detergent sheet production equipment, and in particular to a laundry detergent sheet slicing device. Background Technology

[0002] Laundry detergent sheets are a new type of solid laundry product that replaces traditional liquid or powdered laundry detergent in sheet form. They are gradually entering the market due to their portability, ease of measurement, and environmental friendliness. A laundry detergent sheet slicing machine is the core equipment for the industrial production of laundry detergent sheets; its function is to cut pressed rolls of laundry detergent sheets into standard-sized sheet products.

[0003] Existing methods for slicing laundry sheets mostly employ a longitudinal cutting followed by a transverse cutting method. The laundry sheet substrate produced by the sheet-making machine is conveyed to the longitudinal cutting component and the transverse cutting component in sequence via a conveyor belt. The longitudinal cutting blade is mounted on the longitudinal cutting shaft along the conveying direction and achieves longitudinal cutting through high-speed rotation, cutting the laundry sheet substrate into multiple narrow strips. The transverse cutting blade reciprocates along the conveying direction perpendicular to the narrow strips. When the narrow strips are conveyed to a set length, the transverse cutting blade quickly presses down or moves to cut the narrow strips transversely, forming laundry sheets. The transversely cut laundry sheets fall directly onto the conveyor belt below and are then conveyed to the subsequent packaging process.

[0004] Regarding the aforementioned technologies, the cutting method of longitudinal slicing followed by transverse slicing requires the configuration of longitudinal slicing components and transverse slicing components. The accuracy of adjusting the spacing between the longitudinal slicing blades and the synchronization of the narrow belt conveyor speed and slicing action during transverse slicing are all factors. Any deviation in any of these aspects will lead to inconsistent slice sizes. This results in the accumulation of errors from multiple stages in the final laundry detergent sheet product, leading to poor consistency in laundry detergent sheet size. Furthermore, the cutting method of longitudinal slicing followed by transverse slicing has a complex structure, a large number of parts, and high manufacturing costs. Utility Model Content

[0005] In view of the shortcomings of the existing technology, one of the objectives of this utility model is to provide a laundry sheet slicing device.

[0006] This application provides a laundry detergent sheet slicing device, which adopts the following technical solution: A laundry detergent sheet slicing device includes a frame, a traction mechanism, and a cutting mechanism. The traction mechanism and the cutting mechanism are installed inside the frame. The traction mechanism is located on the side closer to the sheet-making machine, and the cutting mechanism is located on the side closer to the conveyor belt. The surface of the cutting mechanism for cutting is provided with a grid-like blade.

[0007] By adopting the above technical solution, the traction mechanism ensures that the laundry sheet substrate can run automatically and smoothly enter the cutting stage. The design of the grid blades can accurately arrange the blades according to the specifications of the laundry sheet, and simultaneously complete multiple rows and columns of cutting, which significantly improves the cutting efficiency and ensures that the edge height of each sheet is consistent, solving the problem of error accumulation in the traditional method of cutting longitudinally first and then transversely.

[0008] Preferably, the traction mechanism includes two first traction rollers, which are fixed to the inner wall of the frame and installed in a horizontal position. The roller surfaces of the two first traction rollers are in contact and rotate in opposite directions. The axial direction of the two first traction rollers is perpendicular to the conveying direction of the laundry sheet substrate.

[0009] By adopting the above technical solution, the fitted roller surface structure design ensures that the laundry sheet substrate is subjected to uniform force on both sides during the conveying process, avoiding the offset, wrinkling or stretching deformation of the laundry sheet substrate caused by unilateral friction or uneven tension. At the same time, the layout of the two roller axes perpendicular to the conveying direction can accurately constrain the movement trajectory of the laundry sheet substrate, keeping it in a straight conveying state, and providing stable material input conditions for the precise operation of the subsequent cutting mechanism.

[0010] Preferably, the traction mechanism further includes two second traction rollers and two traction belts. The two second traction rollers are fixed to the inner wall of the frame, and their axes are parallel to the axes of the two first traction rollers. The two second traction rollers are located between the two first traction rollers and the cutting mechanism. The traction belts are sleeved on the first and second traction rollers on the same side of the laundry sheet substrate.

[0011] By adopting the above technical solution, the contact area of ​​the laundry detergent sheet substrate is expanded, and the local point contact traction of a single set of rollers is transformed into surface contact traction. This effectively solves the problem of warping caused by insufficient edge pressure when relying solely on the first traction roller. At the same time, the traction belt ensures sufficient traction force to drive the laundry detergent sheet substrate to move stably.

[0012] Preferably, the traction belt is made of rubber.

[0013] By adopting the above technical solution, the high elasticity of rubber enables the traction belt to adapt to changes in the thickness of the laundry sheet substrate during traction. It maintains a close fit with the surface of the laundry sheet substrate through slight deformation. At the same time, the high coefficient of friction of the rubber traction belt surface provides a stable and reliable driving force for the laundry sheet substrate. Even under high-speed conveying conditions, it can effectively prevent slippage and ensure that the laundry sheet substrate enters the cutting mechanism at a constant speed.

[0014] Preferably, the cutting mechanism includes an upper cutter roller and a lower cutter roller, the upper cutter roller being located directly above the lower cutter roller, the surface of the upper cutter roller being a grid-like blade, and the roller surface of the lower cutter roller being smooth.

[0015] By adopting the above technical solution, the surface of the upper roller of the cutter is a grid-shaped blade, and the roller surface of the lower roller of the cutter is smooth, ensuring that the cutting force is evenly distributed across the entire width of the laundry sheet substrate. In conjunction with the upstream traction mechanism, the laundry sheet substrate can stably enter the cutting area, thereby realizing the synchronous and precise cutting of multiple rows and columns of laundry sheets by the grid-shaped blade, meeting the needs of high-speed production, avoiding the complex cutting method of first cutting longitudinally and then transversely, and also avoiding the problem of error accumulation in multiple stages.

[0016] Preferably, the upper roller with mesh blades and the lower roller with cutter are made of stainless steel.

[0017] By adopting the above technical solutions, stainless steel has excellent corrosion resistance, which can effectively resist the erosion of chemical components such as surfactants and solvents that may be contained in the laundry detergent sheet substrate. This prevents the blade from developing gaps or becoming dull due to corrosion, thus maintaining cutting accuracy over a long period of time. In addition, the smooth and high hardness of stainless steel reduces the adhesion of the laundry detergent sheet substrate during the cutting process. At the same time, the high hardness of stainless steel ensures that the blade remains sharp during long-term high-frequency cutting, reducing the problem of incomplete cutting caused by blade wear.

[0018] Preferably, a drive device is provided on the outside of the frame, and gears are provided on the rotating shafts of the traction mechanism and the cutting mechanism. The motor output shaft of the drive device is coaxially linked with the traction mechanism, and the traction mechanism and the cutting mechanism are driven by gear meshing.

[0019] By adopting the above technical solution, the motor output shaft of the drive device is coaxially linked with the traction mechanism, which can directly and efficiently transmit power to the traction mechanism, reducing power loss and transmission error. The traction mechanism and the cutting mechanism are driven by gear meshing. The precise transmission ratio of the gear transmission ensures that the rotation speed of the two is always strictly matched, so that the conveying speed of the laundry sheet substrate is highly synchronized with the working frequency of the cutting mechanism. This avoids problems such as stretching and deformation of the laundry sheet substrate and cutting misalignment caused by speed difference, ensuring the accuracy and quality of laundry sheet substrate cutting, improving production efficiency and reducing the defect rate.

[0020] In summary, this application includes at least one of the following beneficial technical effects: 1. The traction mechanism ensures that the laundry sheet substrate can run automatically and smoothly enter the cutting stage. The grid-shaped blade design can accurately lay out the blades according to the specifications of the laundry sheet, and simultaneously complete multiple rows and columns of cutting, which significantly improves cutting efficiency and ensures that the edge height of each sheet is consistent, solving the problem of error accumulation in the traditional method of cutting longitudinally first and then transversely. 2. The fitted roller surface structure design ensures that the laundry sheet substrate is subjected to uniform force on both sides during the conveying process, avoiding the offset, wrinkling or stretching deformation of the laundry sheet substrate caused by unilateral friction or uneven tension. At the same time, the layout of the two roller axes perpendicular to the conveying direction can accurately constrain the movement trajectory of the laundry sheet substrate, keeping it in a straight conveying state, and providing stable material input conditions for the precise operation of the subsequent cutting mechanism. 3. The upper roller of the cutter has a grid-like blade surface, and the lower roller of the cutter has a smooth roller surface, ensuring that the cutting force is evenly distributed across the entire width of the laundry sheet substrate. In conjunction with the upstream traction mechanism, the laundry sheet substrate can stably enter the cutting area, thereby achieving synchronous and precise cutting of multiple rows and columns of laundry sheets by the grid-like blade. This meets the needs of high-speed production, avoids the complex cutting method of first cutting longitudinally and then transversely, and also avoids the problem of error accumulation in multiple stages.

Detailed Implementation

[0023] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 This application will be described in further detail.

[0024] This application discloses a laundry detergent sheet slicing device.

[0025] Reference Figure 1 and Figure 2 A laundry detergent sheet slicing device includes a frame 1, a traction mechanism 2, and a cutting mechanism 3. A sheet-making machine 01 is located near the frame 1, and a conveyor belt 02 is located on the side of the frame 1 away from the sheet-making machine 01. The traction mechanism 2 and the cutting mechanism 3 are disposed inside the frame 1. The traction mechanism 2 is located on the side closer to the sheet-making machine 01, and the cutting mechanism 3 is located on the side closer to the conveyor belt 02. The cutting mechanism 3 is used to cut laundry detergent sheets.

[0026] The traction mechanism 2 includes two first traction rollers 201, two second traction rollers 202, and two traction belts 203. The two first traction rollers 201 are fixed to the inner wall of the frame 1 and installed in a horizontally symmetrical manner. The roller surfaces of the two rollers are in contact and rotate in opposite directions. The axial direction of the two first traction rollers 201 is perpendicular to the conveying direction of the laundry sheet substrate 03. The two second traction rollers 202 are fixed to the inner wall of the frame 1, and their axes are parallel to the axes of the two first traction rollers 201. The two second traction rollers 202 are located between the two first traction rollers 201 and the cutting mechanism 3. The traction belts 203 are sleeved on the first traction rollers 201 and the second traction rollers 202 located on the same side of the laundry sheet substrate 03, so that the first traction rollers 201 and the second traction rollers 202 rotate at the same linear speed.

[0027] When the laundry sheet substrate 03 passes through the surface of the two first traction rollers 201, the two first traction rollers 201 squeeze the laundry sheet and use friction to drive the laundry sheet substrate 03 to move stably, ensuring that the laundry sheet substrate 03 can be transported to the working area of ​​the cutting mechanism 3. After being transported by the sheet making machine 01, the laundry sheet substrate 03 passes between the two first traction rollers 201, the second traction roller 202 and the traction belt 203, so that the pressure on the entire surface of the laundry sheet substrate 03 is uniform during the transport process, which optimizes the situation where the edges are easy to curl up when only the two first traction rollers 201 are used for traction.

[0028] In this embodiment, the traction belt 203 is made of rubber. The rubber material has high elasticity, high coefficient of friction, and a smooth and slightly rough surface. The rubber traction belt 203 directly contacts the laundry detergent substrate 03 to provide stable traction force to the laundry detergent substrate 03.

[0029] The cutting mechanism 3 includes an upper cutting roller 301 and a lower cutting roller 302. The upper cutting roller 301 is located directly above the lower cutting roller 302, and both are downstream of the traction mechanism 2. The surface of the upper cutting roller 301 is composed of uniformly distributed and regularly arranged protruding blades, forming a grid-like cutting structure. The surface of the lower cutting roller 302 is smooth. When the laundry sheet passes between the upper cutting roller 301 and the lower cutting roller 302, the upper cutting roller 301 and the lower cutting roller 302 rotate, and the grid-like blades form a shearing action with the surface of the lower cutting roller 302, cutting the laundry sheet substrate 03 into many laundry sheets corresponding to the grid-like blades. The cut laundry sheets fall onto the conveyor belt 02 below under gravity and are transported to subsequent processes by the conveyor belt 02.

[0030] Preferably, the surfaces of the upper cutter roller 301 (grid-shaped blade) and the lower cutter roller 302 are made of stainless steel. The stainless steel cutting mechanism 3 effectively prevents the chemical components in the laundry detergent sheets from corroding the blades. Furthermore, the smooth surface and high hardness of stainless steel help reduce the sticking of laundry detergent sheets and meet general cutting needs.

[0031] Reference Figure 3 and Figure 4 A drive unit 4 is installed on the outer side of the frame 1. Gears 5 are installed on the rotating shafts of two first traction rollers 201, two second traction rollers 202, upper cutter roller 301, and lower cutter roller 302. The motor output shaft of the drive unit 4 is coaxially linked with one of the first traction rollers 201. A synchronous transmission belt 6 is installed on the surface of the two first traction rollers 201 in the vertical direction, and the two are transmitted to each other through the synchronous transmission belt 6. The upper cutter roller 301 and lower cutter roller 302 are respectively transmitted to the two second traction rollers 202 through gear 5. According to the production speed of the laundry sheets, the driving unit 4 precisely controls the running speed of the traction mechanism 2 and the cutting mechanism 3 to ensure that the conveying speed of the laundry sheets is synchronized with the cutting speed during the cutting process, avoiding deformation or misalignment of the slices due to speed difference.

[0032] The implementation principle of this embodiment is as follows: During the operation of the laundry detergent sheet slicing device, firstly, the laundry detergent sheet substrate 03 prepared by the sheet-making machine 01 is conveyed to the traction mechanism 2 and held by two first traction rollers 201. The roller surfaces of the two rollers are in close contact, pressing the laundry detergent sheet substrate 03, and the traction belt 203 drives the laundry detergent sheet substrate 03 to be steadily conveyed forward. At the same time, two second traction rollers 202 located downstream of the first traction rollers 201 are linked by the traction belt 203 to apply uniform pressure to the entire surface of the laundry detergent sheet substrate 03, preventing the edges of the laundry detergent sheet substrate 03 from warping due to uneven force, and ensuring that the laundry detergent sheet substrate 03 enters the cutting stage flat. Subsequently, the laundry sheet substrate 03 is drawn to the cutting mechanism 3. The upper cutter roller 301 and the lower cutter roller 302 work together. The grid-like blades on the surface of the upper cutter roller 301 rotate with the roller body and form a shearing action with the roller surface of the lower cutter roller 302, accurately cutting the laundry sheet substrate 03 into laundry sheets. The cut laundry sheets detach from the laundry sheet substrate 03 under the action of inertia and fall onto the conveyor belt 02 by their own gravity, and are transported by the conveyor belt 02 to the packaging or stacking process.

[0033] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
