Description

TECHNICAL FIELD

[0001] The utility model relates to measuring cutting device technical field, concretely relates to a measuring cutting device. BACKGROUND

[0002] Plastic cloth and plastic film are important packaging materials in aluminum roll packaging, and their main function is to prevent aluminum roll from oxidizing during transportation and storage process, which belongs to disposable consumables and has very large consumption. All aluminum roll packaging needs to use plastic cloth or plastic film, for example, about 10 tons of plastic cloth can be used per month, and if 50 centimeters of plastic cloth can be saved for each aluminum roll packaging, a large amount of cost can be saved per year. In the past, the cutting of plastic cloth and plastic film in the packaging and discharging process of aluminum roll was relied on human experience, and the length of plastic cloth and plastic film was measured by stretching the arms, and then a certain length of plastic cloth and plastic film was cut manually with a paper cutter, but the cut plastic cloth and plastic film had large error and different lengths, causing waste. Therefore, a measuring cutting device is needed to solve the above problems. SUMMARY

[0003] In order to solve the technical problem that the cutting of plastic cloth and plastic film is now relied on human experience, the length of plastic cloth and plastic film is measured by stretching the arms, and then cut, resulting in large error and different lengths of cut plastic cloth and plastic film, the utility model provides a measuring cutting device, which is simple in structure and convenient to operate, no longer relies on the arms to measure the length of plastic cloth, accurately measures the plastic cloth, and manually cuts the plastic cloth at a faster speed.

[0004] The utility model provides a kind of measuring cutting device, including unwinding assembly and measuring component, the unwinding assembly includes unwinding rack and the unwinding roller of fixed setting in unwinding rack, the measuring component includes measuring rack, two fixed rods and movable rod, the measuring rack is fixedly arranged in the one side of unwinding rack close to unwinding roller, rotating shaft is rotatably arranged on the measuring rack, the both ends of rotating shaft are all through first rotating rod and second rotating rod and first rotating rod and second rotating rod are perpendicular, two fixed rods are respectively fixedly arranged between the both ends of two first rotating rods, and two fixed rods are parallel, two movable rods are respectively movably arranged between the both ends of two second rotating rods, and two movable rods are parallel, one end of rotating shaft is also fixedly connected with rotating handle.

[0005] Furthermore, each of the movable rods has a hollow sleeve fixedly installed at both ends. The two hollow sleeves on each movable rod are slidably mounted on two second rotating rods. Each hollow sleeve has a threaded hole through which a bolt passes and abuts against the second rotating rod. When the bolt is tightened, the bolt passes through the threaded hole and abuts against the second rotating rod, fixing the hollow sleeve to the second rotating rod and preventing it from sliding. Conversely, when the bolt is manually loosened, the hollow sleeve can slide on the second rotating rod.

[0006] Furthermore, a rubber ring is fixedly installed on the outer surface of each hollow sleeve, and an opening is provided at the position corresponding to the threaded hole of the rubber ring. When the plastic sheet is wrapped around the fixed rod and the movable rod, the plastic sheet may scratch the corner of the hollow sleeve and be damaged. After the rubber ring is fixedly installed on the outer surface of the hollow sleeve, the rubber ring can prevent the hollow sleeve from scratching the plastic sheet. The opening makes room for the bolt and does not affect the tightening or loosening of the hollow sleeve.

[0007] Furthermore, the second rotating rod is longer than the first rotating rod, and both ends of the second rotating rod are fixedly equipped with plugs, while a scale line is fixedly installed in the middle of the second rotating rod. The plugs limit the sliding range of the movable rod and prevent it from detaching from the second rotating rod. The scale line facilitates sliding the movable rod, thereby adjusting the positions of the two movable rods.

[0008] Furthermore, the measuring frame includes a measuring base and two inverted U-shaped supports fixedly mounted at both ends of the measuring base. Each of the two inverted U-shaped supports is equipped with a bearing seat. The two ends of the rotating shaft pass through the rotary bearings on the two bearing seats and rotate within them. The first rotating rod and the second rotating rod are located in the middle of the two inverted U-shaped supports, and the rotating handle is located on the outside of the two inverted U-shaped supports. Manually rotating the rotating handle causes the two ends of the rotating shaft to rotate within the rotary bearings on the two bearing seats, thereby causing the first rotating rod, the second rotating rod, the fixed rod, and the movable rod on the rotating shaft to rotate.

[0009] Furthermore, multiple unwinding rollers are provided, arranged sequentially along the height of the unwinding frame and at an angle. The distance between the uppermost unwinding roller and the measuring frame is greater than the distance between the lowermost unwinding roller and the measuring frame. This angled arrangement of the multiple unwinding rollers facilitates the loading of multiple rolls onto the unwinding rollers, thereby accelerating the cutting speed of the rolls.

[0010] Furthermore, the unwinding frame includes an unwinding base and two columns fixedly mounted at both ends of the unwinding base. Each column has a U-shaped seat fixedly mounted on its top, and the U-shaped seat has a slot. One unwinding roller has both ends passing through two slots and secured thereon. An inclined rod is inclined between each column and the unwinding base, and multiple bearing sleeves are evenly fixedly mounted on each inclined rod. The remaining unwinding rollers have both ends passing through two bearing sleeves on the same horizontal line and fixedly connected to them. The material roll rotates relative to the unwinding rollers to achieve unwinding.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This utility model's measuring and cutting device allows for manual rotation of the handle, causing the rotating shaft to rotate. The first rotating rod, second rotating rod, fixed rod, and movable rod rotate around the rotating shaft, thus winding the plastic sheet around the fixed and movable rods. After a fixed number of rotations, the operator uses a cutting blade to cut the plastic sheet on the fixed and movable rods and the unwinding roller. Due to the physical effect of tension contraction, the cut plastic sheet on the fixed and movable rods is generally 20 cm longer than the total circumference of all the aluminum rolls (multiple rolls) to be packaged. Compared to measuring the plastic sheet with both arms, the final total length of the plastic sheet would be 70 cm longer, saving 50 cm. The measuring and cutting device has a simple structure and is easy to operate. It eliminates the need for manual measurement of the plastic sheet length, allowing for precise measurement and faster manual cutting. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-4 As shown, a measuring and cutting device includes an unwinding assembly 1 and a measuring assembly 2. The unwinding assembly 1 includes an unwinding frame 11 and an unwinding roller 12 fixedly mounted on the unwinding frame 11. The measuring assembly 2 includes a measuring frame 21, two fixed rods 22, and a movable rod 23. The measuring frame 21 is fixedly mounted on one side of the unwinding frame 11 near the unwinding roller 12. A rotating shaft 24 is rotatably mounted on the measuring frame 21. A first rotating rod 25 and a second rotating rod 26 are passed through both ends of the rotating shaft 24, and the first rotating rod 25 and the second rotating rod 26 are perpendicular to each other. All rotating rods 26 pass through the ends of the rotating shaft 24 and are welded and fixed thereon. The first rotating rod 25 and the first rotating rod 26 are divided into two equal-length upper and lower parts by the rotating shaft 24. The two fixed rods 22 are respectively fixed between the two ends of the two first rotating rods 25. The two fixed rods 22 are parallel to each other and are located on both sides of the rotating shaft 24. The two movable rods 23 are respectively movably disposed between the two ends of the two second rotating rods 26 and are parallel to each other. The two movable rods 23 are located on both sides of the rotating shaft 24. A rotating handle 3 is also fixedly connected to one end of the rotating shaft 24.

[0021] When the measuring and cutting device is in use, the two movable rods 23 are fixed between the two ends of the two second rotating rods 26.

[0022] The principle of quadrilateral perimeter is adopted. According to the required perimeter of the aluminum coil to be packaged, the positions of the two movable rods 23 are adjusted and fixed. The perimeter of the quadrilateral formed by the two movable rods 23 and the fixed rod 22 can be calculated or measured according to the positions of the two movable rods 23 and the fixed rod 22. The horizontal line connecting the two movable rods 23 and the horizontal line connecting the two fixed rods 22 are the two perpendicular diagonals of the quadrilateral.

[0023] Specifically, the perimeter of the quadrilateral can be measured using a measuring ruler, and this perimeter is equal to the required perimeter of the aluminum coil to be packaged. In this embodiment, the perimeter of the quadrilateral formed by the two movable rods 23 and the fixed rod 22 can be adjusted arbitrarily between 1m and 2.8m. The positions of the two movable rods 23 on the second rotating rod 26 can be adjusted, thereby allowing for adjustment of the perimeter of the quadrilateral formed by the two movable rods 23 and the fixed rod 22. This allows for the accommodating of packaging requirements for aluminum coils with varying perimeters.

[0024] The working process of the measuring and cutting device is as follows: When cutting the material roll (plastic cloth roll, plastic film roll), the plastic cloth roll is placed on the unwinding roller 12. Then, a person pulls the material head of the plastic cloth roll. When the material head is pulled, the plastic cloth roll rotates relative to the unwinding roller 12 to release the material. Then, the material head is manually wound around a fixed rod 22, and the person manually turns the rotating handle 3. The rotating shaft 24 rotates, and the first rotating rod 25, the second rotating rod 26, the fixed rod 22, and the movable rod 23 rotate around the rotating shaft 24 as the central axis, thereby driving the plastic cloth to wrap around the fixed rod 22 and the movable rod 23. Because the first rotating rod 25 and the second rotating rod 26 are perpendicular, and the two fixed rods 22 and the two movable rods 23 are parallel to each other, this ensures that the plastic cloth can be wrapped around the fixed rod 22 and the movable rod 23 without falling off.

[0025] A person rotates the machine a fixed number of times, then uses a cutter to cut the plastic sheet on the fixed rod 22 and movable rod 23, as well as the plastic sheet on the unwinding roller 12. Due to the physical effect of tension contraction, the cut plastic sheet on the fixed rod 22 and movable rod 23 is generally 20 cm longer than the total circumference of all the aluminum coils (multiple aluminum coils) to be packaged. Compared to measuring the total length of the plastic sheet with both arms, which would be 70 cm longer, this saves 50 cm. For example, if the circumference of the aluminum coil to be packaged is 2m, and the circumference of the quadrilateral is also set to 2m, then after manually rotating the machine 5 times before cutting, the length of the plastic sheet on the fixed rod 22 and movable rod 23 will be 10.2 meters. This 10.2m of plastic sheet is then used to package 5 aluminum coils sequentially.

[0026] The measuring and cutting device in this embodiment has a simple structure and is easy to operate. It eliminates the need for a person to measure the length of the plastic sheet with their arms, and accurately measures the plastic sheet, thereby speeding up the manual cutting of the plastic sheet. It also has the advantages of occupying little space and being easy to move.

[0027] This method also saves costs and reduces the labor intensity of workers. Cutting plastic sheeting requires only one person and is highly efficient, capable of cutting 100 sheets in 5 minutes with no length error and no waste. The operation is very simple. Based on a monthly production of 15,000 pieces of finished plastic sheeting, saving 0.5 meters of plastic sheeting per piece amounts to 7,500 meters per month, approximately 500 kilograms. At 10,000 yuan per kilogram of plastic sheeting, this translates to 5,000 yuan per month, and 60,000 yuan per year.

[0028] In one possible implementation, each movable rod 23 has a hollow sleeve 231 fixedly installed at both ends. The hollow sleeve 231 is welded and fixed to the ends of the movable rod 23. The two hollow sleeves 231 on each movable rod 23 are slidably mounted on the two second rotating rods 26. The hollow sleeve 231 has a threaded hole, through which a bolt 4 passes and abuts against the second rotating rod 26. When the bolt 4 is tightened, the bolt 4 passes through the threaded hole and abuts against the second rotating rod 26, fixing the hollow sleeve 231 to the second rotating rod 26 and preventing it from sliding. At this time, the two movable rods 23 are fixed between the two ends of the two second rotating rods 26 and cannot slide. Conversely, when the bolt 4 is manually loosened, the hollow sleeve 231 can slide on the second rotating rod 26, changing its position on the second rotating rod 26, thereby adjusting the position of the movable rod 23. By adjusting the position of the two movable rods 23, the perimeter of the aforementioned quadrilateral is adjusted, meeting the different length cutting requirements of the plastic sheet.

[0029] As one possible implementation, a rubber ring 232 is fixedly provided on the outer surface of each hollow sleeve 231, and an opening is provided at the position corresponding to the threaded hole of the rubber ring 232. When the plastic cloth is wrapped around the fixed rod 22 and the movable rod 23, the plastic cloth may scratch the corner of the hollow sleeve 231 and be damaged. After the rubber ring 232 is fixedly provided on the outer surface of the hollow sleeve 231, the rubber ring 232 can prevent the hollow sleeve 231 from scratching the plastic cloth. The opening makes room for the bolt 4, without affecting the tightening or loosening of the hollow sleeve 231 by the bolt 4.

[0030] In one possible implementation, the length of the second rotating rod 26 is greater than the length of the first rotating rod 25, resulting in a larger adjustable range for the movable rod 23. This allows for the fulfillment of different length cutting requirements for plastic sheeting. Both ends of the second rotating rod 26 are fixedly equipped with end caps 261, which are welded to the ends of the second rotating rod 26. A scale line is fixedly provided in the middle of the second rotating rod 26. The end caps 261 on the two second rotating rods 26 restrict the sliding range of the movable rod 23 located on one side of the rotating shaft 24, preventing the movable rod 23 from detaching from the two second rotating rods 26. The scale line facilitates sliding the movable rod 23, thereby adjusting the position of the two movable rods 23.

[0031] In one possible implementation, the measuring frame 21 includes a measuring base and two inverted U-shaped supports fixedly disposed at both ends of the measuring base. The measuring base and the two inverted U-shaped supports are welded together. Each of the two inverted U-shaped supports is provided with a bearing seat 211, which is welded to the top of the inverted U-shaped support. The two ends of the rotating shaft 24 pass through the rotating bearings on the two bearing seats 211 and rotate within the rotating bearings. The first rotating rod 25 and the second rotating rod 26 are located in the middle of the two inverted U-shaped supports, and the rotating handle 3 is located on the outside of the two inverted U-shaped supports. When the rotating handle 3 is manually rotated, the two ends of the rotating shaft 24 rotate within the rotating bearings on the two bearing seats 211, thereby causing the first rotating rod 25, the second rotating rod 26, the fixed rod 22, and the movable rod 23 on the rotating shaft 24 to rotate.

[0032] In one possible implementation, multiple unwinding rollers 12 are provided, arranged sequentially along the height direction of the unwinding frame 11, and the multiple unwinding rollers 12 are arranged at an angle. The distance between the uppermost unwinding roller 12 and the measuring frame 21 is greater than the distance between the lowermost unwinding roller 12 and the measuring frame 21. See also Figure 3 The diagram illustrates a material roll mounted on the bottom unwinding roller 12. Multiple unwinding rollers 12 allow for the simultaneous loading of multiple plastic fabric rolls and / or plastic film rolls onto the unwinding frame 11. Once a plastic fabric roll is cut, a new roll can be immediately replaced for cutting. Similarly, once all rolls on the unwinding frame 11 have been cut, multiple new rolls can be replaced at once. The inclined arrangement of the multiple unwinding rollers 12 facilitates the loading of multiple rolls, thereby accelerating the cutting speed.

[0033] In one possible implementation, the unwinding frame 11 includes an unwinding base and two columns fixedly disposed at both ends of the unwinding base. Each column has a U-shaped seat 111 fixedly disposed at its top, and the U-shaped seat 111 has a slot. The U-shaped seat 111 is welded and fixed to the top of the column. One of the unwinding rollers 12 has both ends passing through the two slots and being engaged thereon. An inclined rod is provided between each column and the unwinding base. The unwinding base, the two columns, and the inclined rod are welded and fixed. Multiple bearing sleeves 112 are evenly fixedly disposed on each inclined rod, and the bearing sleeves 112 are welded and fixed to the inclined rod. The remaining unwinding rollers 12 have both ends passing through and fixedly connected to two bearing sleeves 112 at the same horizontal line. In use, plastic fabric rolls and / or plastic film rolls are respectively mounted on the multiple unwinding rollers 12. The material rolls rotate relative to the unwinding rollers 12 to achieve unwinding.

[0034] Furthermore, one end of the unwinding roller 12 passes through and is engaged in the slot, thus fixing the end of the unwinding roller 12 to the U-shaped seat 111. The size of the slot is slightly larger than the size of the end of the unwinding roller 12, ensuring that the end of the unwinding roller 12 is engaged in the slot and cannot rotate.

[0035] Furthermore, both ends of the bearing sleeve 112 and the remaining unwinding roller 12 are provided with pin holes. The pin shaft passes through the pin holes at the ends of the bearing sleeve 112 and the unwinding roller 12 to fix the end of the unwinding roller 12 onto the bearing sleeve 112.

[0036] As one possible implementation, both the measuring base and the unwinding base are equipped with locking wheels. The structure of the locking wheels is existing technology and will not be described further here. When it is necessary to move the measuring and cutting device, the locking wheels are opened; when it is necessary to fix the measuring and cutting device, the locking wheels are closed. Moving the measuring and cutting device is easier for a person using the locking wheels.

[0037] The embodiments described above are merely preferred embodiments of this utility model and are only used to explain this utility model. They are not intended to limit the scope of implementation of this utility model. For those skilled in the art, other implementation methods can be easily made by substitution or modification based on the technical content disclosed in this specification. Therefore, all changes and improvements made to the principles and process conditions of this utility model should be included within the scope of the patent application of this utility model.
