Description

Technical Field

[0001] This utility model relates to the field of food packaging production technology, specifically a paper-holding trolley for a food packaging production line. Background Technology

[0002] Food packaging refers to the process of wrapping food with appropriate packaging materials, containers, and technologies to maintain its value and original state during transportation and storage. Currently, in food packaging production, paper rolls are often stored in multiple horizontal stacks. When loading paper rolls onto the unwinding shaft, workers must first stand the horizontally stacked rolls upright, then insert the unwinding shaft into the roll to secure it, and then carefully move the secured roll onto the loading trolley for subsequent feeding operations. However, because the paper rolls themselves are quite heavy, this process requires workers to expend a lot of physical strength, is not only labor-intensive, but also carries the safety risk of being injured by falling heavy objects if their hands slip. Utility Model Content

[0003] The purpose of this invention is to provide a paper-holding trolley for a food packaging production line, which effectively solves the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution.

[0005] A paper-holding trolley for a food packaging production line includes a frame, a lifting plate slidably mounted on the inner side of the frame, a first hydraulic cylinder mounted on the inner side of the frame, the telescopic end of the first hydraulic cylinder being connected to the lifting plate, a fixed shaft mounted on the outer surface of the lifting plate, a sleeve rotatably mounted on the outer surface of the fixed shaft, and a flipping mechanism provided between the sleeve and the fixed shaft. A mounting seat is mounted on the end of the sleeve, and clamping arms are rotatably mounted on both sides of the mounting seat. A second hydraulic cylinder is disposed inside the mounting seat, with its two ends rotatably connected to the two clamping arms respectively. Clamping blocks are rotatably mounted on the ends of the clamping arms via connecting shafts, and an angle adjustment mechanism is provided on the outer side of the connecting shaft.

[0006] As can be seen, by driving the two clamping arms to flip inward simultaneously through the second hydraulic cylinder, the two clamping blocks can be clamped on the outside of the paper roll. Then, the mounting base is rotated 90 degrees by the flipping mechanism, so that the paper roll can be stood up and inserted into the unwinding shaft, and then placed on the paper loading trolley. This avoids the physical exertion and safety hazards caused by manual handling, and is highly practical. Furthermore, the angle adjustment mechanism can be used to adjust the angle of the clamping blocks, so that paper rolls of different diameters can be clamped and transported, which has a wide range of applications and increases the flexibility of this device.

[0007] Furthermore, the flipping mechanism includes a sleeve rod installed on the outer surface of the sleeve, an insert rod inserted inside the sleeve rod, four first positioning holes coaxially arrayed on the outer surface of the fixed shaft, and the insert rod matching the first positioning holes, an inner groove on the inner wall of the sleeve rod, a shoulder on the outer surface of the insert rod, and a spring sleeved on the outer surface of the insert rod, with the two ends of the spring abutting against the shoulder and the inner wall of the inner groove, respectively.

[0008] Furthermore, the angle adjustment mechanism includes a worm gear mounted on the end of the connecting shaft, two side blocks mounted on the outer surface of the clamping arm, a worm gear rotatably connected between the two side blocks, and the worm gear meshing with the side blocks.

[0009] Furthermore, one of the side blocks has multiple second positioning holes on its outer surface surrounding the worm gear coaxial array, and bolts are installed at the ends of the worm gear, with the bolts matching the second positioning holes.

[0010] Furthermore, a rubber pad is provided on the outer surface of the clamping block, and the outer surface of the rubber pad is provided with anti-slip texture.

[0011] Furthermore, a handle is installed at the upper end of the insertion rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0013] 1. This utility model uses a second hydraulic cylinder to drive two clamping arms to flip inwards simultaneously, thereby causing two clamping blocks to clamp the outside of the paper roll. Then, the mounting base is flipped 90 degrees by a flipping mechanism, so that the paper roll can be stood up and inserted into the unwinding shaft, and then placed on the paper loading trolley. This avoids the physical exertion and safety hazards caused by manual handling, and is highly practical.

[0014] 2. This utility model uses a rotating worm gear. Since the worm gear meshes with the side block, it can drive the connecting shaft to rotate and achieve the purpose of adjusting the angle of the clamping block. By adjusting the angle of the two clamping blocks, it can be used to clamp paper rolls of different diameters, increasing the flexibility of this device. Attached Figure Description

Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0024] Please see Figures 1-5This utility model provides a paper-holding trolley for a food packaging production line, including a frame 100. A lifting plate 101 is slidably mounted on the inner side of the frame 100. A first hydraulic cylinder 102 is mounted on the inner side of the frame 100. The end of the telescopic end of the first hydraulic cylinder 102 is connected to the lifting plate 101. A fixed shaft 103 is mounted on the outer surface of the lifting plate 101. A sleeve 104 is rotatably mounted on the outer surface of the fixed shaft 103. A flipping mechanism 200 is provided between the sleeve 104 and the fixed shaft 103. A mounting seat 105 is mounted on the end of the sleeve 104. Clamping arms 106 are rotatably mounted on both sides of the mounting seat 105. A second hydraulic cylinder 107 is provided inside the mounting seat 105. The two ends of the second hydraulic cylinder 107 are rotatably connected to the two clamping arms 106 respectively. A clamping block 108 is rotatably mounted on the end of the clamping arm 106 through a connecting shaft 109. An angle adjustment mechanism 300 is provided on the outer side of the connecting shaft 109.

[0025] In use, first move the device to the paper roll storage area, then activate the first hydraulic cylinder 102 to raise the lifting plate 101, so that the two clamping blocks 108 are at the same height as the paper roll and located on both sides of the paper roll. Then activate the second hydraulic cylinder 107, and extend the telescopic end of the second hydraulic cylinder 107 outward, so that the two clamping arms 106 can flip inward at the same time, and drive the two clamping blocks 108 to clamp and fix them on both sides of the paper roll. Then, the first hydraulic cylinder 102 drives the paper roll to rise to a certain height, and the rotating mechanism 200 rotates the mounting base 105 90 degrees, thereby standing the paper roll upright. At this time, the worker can insert the unwinding shaft into the paper roll to fix it, and then drive the paper roll to fall through the first hydraulic cylinder 102, so that the two ends of the unwinding shaft are placed in the grooves of the paper loading trolley fork arm. Furthermore, the angle adjustment mechanism 300 can be used to adjust the angle of the clamping blocks 108, so that paper rolls of different diameters can be clamped and transported, which has a wide range of applications and increases the flexibility of the device.

[0026] Specifically, the flipping mechanism 200 includes a sleeve rod 201 mounted on the outer surface of the sleeve 104, an insert rod 202 inserted inside the sleeve rod 201, four first positioning holes 203 coaxially arrayed on the outer surface of the fixed shaft 103, and the insert rod 202 matching the first positioning holes 203, an inner groove 204 formed on the inner wall of the sleeve rod 201, a shoulder 205 provided on the outer surface of the insert rod 202, and a spring 206 sleeved on the outer surface of the insert rod 202, with the two ends of the spring 206 respectively engaging with the shoulder 205 and the inner groove 204. The inner wall of the sleeve 104 abuts against the paper roll. When it is necessary to flip the paper roll, the insert rod 202 can be pulled outward so that its end is pulled out from the first positioning hole 203. Then, the sleeve rod 201 is pulled to flip the paper roll. During the flipping process, the insert rod 202 is subjected to the elastic force of the spring 206, and its end is always abutting against the outer surface of the fixed shaft 103. When the sleeve 104 is flipped 90 degrees, the compressed spring 206 releases its elastic force, which can drive the insert rod 202 to automatically insert into the first positioning hole 203 and fix it, thereby achieving the purpose of flipping the paper roll.

[0027] Specifically, the angle adjustment mechanism 300 includes a worm gear 301 installed at the end of the connecting shaft 109, two side blocks 302 installed on the outer surface of the clamping arm 106, and a worm 303 rotatably connected between the two side blocks 302. The worm 303 meshes with the side blocks 302. When it is necessary to adjust the angle of the clamping block 108, simply rotate the worm 303. Since the worm 303 meshes with the side blocks 302, it can drive the connecting shaft 109 to rotate and achieve the purpose of adjusting the angle of the clamping block 108. By adjusting the angle of the two clamping blocks 108, it can be used to clamp paper rolls of different diameters.

[0028] Specifically, one of the side blocks 302 has multiple second positioning holes 400 arranged coaxially around the worm 303 on its outer surface. A bolt 401 is installed at the end of the worm 303. The bolt 401 matches the second positioning hole 400. Before rotating the worm 303, the bolt 401 is first unscrewed from the second positioning hole 400. After the angle of the clamping block 108 is adjusted, the bolt 401 is screwed back into the second positioning hole 400, thereby locking the worm 303 and ensuring the stability of the angle of the clamping block 108.

[0029] Specifically, the outer surface of the clamping block 108 is provided with a rubber pad 500, and the outer surface of the rubber pad 500 is provided with anti-slip texture. The rubber pad 500 can play a protective role when clamping the paper roll, preventing damage to the paper roll. In addition, the anti-slip texture can increase the friction between the clamping block 108 and the paper roll, further improving the clamping effect and preventing the paper roll from falling.

[0030] Specifically, a handle 600 is installed at the upper end of the insertion rod 202. The handle 600 makes it easy to pull the insertion rod 202 outward and prevents the hand from slipping.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
