Description

Technical Field

[0001] This utility model relates to the field of roller installation technology, specifically to an adjustable roller installation structure for a food packaging machine. Background Technology

[0002] Food packaging machines are core equipment in automated production, integrating bag making, metering, filling, sealing, and cutting. Through mechanical transmission and a precise temperature control system, they achieve efficient aseptic packaging of various foods (such as snacks, frozen products, and liquid seasonings), supporting multiple forms such as bagged and boxed packaging. The rollers of food packaging machines are the core execution components of the packaging production line, undertaking key functions such as film conveying, tension control, and sealing. They adopt a high-precision processed cylindrical structure with a chrome-plated or Teflon-treated surface, combining wear resistance and low friction characteristics, and can adapt to the stable operation of packaging films of different materials.

[0003] During the installation and use of rollers in food packaging machines, the rollers are fitted onto the outside of corresponding mounting rods and then secured from the side of the mounting rods using appropriate threaded sleeves. However, the required roller diameters vary depending on the packaging bags used for different production needs. Consequently, the support diameter and length of the mounting rods themselves differ during installation, making it impossible to adjust the mounting rod diameter appropriately. This results in unstable installation of rollers of different sizes, affecting the stable conveying of subsequent packaging bags. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide an adjustable roller installation structure for food packaging machines. This addresses the current practice in food packaging machines where the roller is fitted onto the outside of a mounting rod and then fixed from the side of the mounting rod using a screw sleeve. However, different production needs require different roller diameters for the packaging bags used, resulting in varying support diameters and lengths of the mounting rod itself. This makes it impossible to adjust the diameter of the mounting rod appropriately during roller installation, leading to unstable installation of rollers of different sizes and affecting the stable conveying of subsequent packaging bags.

[0005] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: an adjustable food packaging machine roller installation structure is designed, including an installation base, a support plate is vertically fixedly installed on the top of the installation base, a fixed plate is fixedly installed on the top surface of the support plate, a movable tube is slidably installed through the middle of the side of the fixed plate, and a retaining arc plate is equidistantly installed on the outside of the movable tube.

[0006] A pushing mechanism is provided between the movable tube and the pressing arc plate, and four sets of guiding mechanisms are fixedly installed at equal intervals on the side of the fixed plate, and the guiding mechanisms are connected to the pushing mechanism;

[0007] The movable tube side end is detachably installed with a connecting tube via a connecting mechanism.

[0008] Preferably, a protective circular frame is fixedly installed on the side of the fixing plate away from the connecting pipe, and an electric push rod is fixedly installed at the middle of the outer wall of the protective circular frame, and the side end of the electric push rod is fixedly connected to the outer wall of the movable pipe.

[0009] Preferably, the guiding mechanism includes a guide frame, four sets of guide frames are fixedly installed at equal intervals on the side of the fixed plate, a first mounting plate is slidably installed on the side of the guide frame, the side of the first mounting plate away from the movable tube is connected to the outer wall of the abutting arc plate, and a second mounting plate is detachably installed on the side of the first mounting plate.

[0010] Preferably, a guide slider is fixedly installed on the side of the first mounting plate near the fixed plate, and a guide groove is provided inside the guide frame, and the guide slider is slidably installed inside the guide groove.

[0011] Preferably, the pushing mechanism includes a pushing block and a transmission block. Several sets of connecting blocks are fixedly installed at equal intervals on the outer walls of the movable tube and the connecting tube. The pushing block is fixedly installed on the side of the connecting block away from the movable tube. Several sets of transmission blocks are fixedly installed at equal intervals on the side of the first mounting plate and the second mounting plate close to the movable tube.

[0012] Preferably, the connecting mechanism includes a connecting screw, and connecting screw holes are laterally opened in the middle of the side of the movable tube and the connecting tube away from the fixed plate. The connecting screw is laterally fixedly installed in the middle of the side of the connecting tube close to the fixed plate.

[0013] Preferably, a number of sets of connecting bolts are equidistantly inserted into the top side of the abutting arc plate, and the bottom end of the connecting bolts is screwed into the top of the first mounting plate by threads.

[0014] Preferably, both ends of the first mounting plate and the second mounting plate are provided with insertion slots, and the second mounting plate is horizontally fixedly installed with insertion flexible posts on both sides near the first mounting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model features a movable tube slidably mounted on the middle of the side of a fixed plate, with several sets of pushing blocks equidistantly arranged on the outer side of the movable tube. Combined with four sets of first mounting plates slidably mounted on the outer side of the fixed plate, and several sets of transmission blocks arranged on the outer side of each first mounting plate, the movable tube and the pushing blocks on its surface can be synchronously moved horizontally under the driving action of the electric actuator. This causes the inclined surfaces of the pushing blocks and the transmission blocks to contact each other. As the pushing blocks continue to move to the right, a corresponding lateral pushing force is provided to the transmission blocks, allowing the transmission blocks to move horizontally along with the pushing blocks. The four sets of abutting arc plates move synchronously relative to each other on the outside of the movable tube. With the guidance of the guide slide inside the guide frame, the abutting arc plates can be provided with corresponding outward driving force. This allows the four sets of abutting arc plates to move synchronously relative to each other as the movable tube moves to the right. Adjusting the distance between the four sets of abutting arc plates ensures that the outer wall of the abutting arc plate can fully fit against the inner wall of the roller. While fixing the roller by abutting, the push block and the transmission block make full contact. The push block can provide sufficient support to the transmission block, ensuring that the abutting arc plates can provide sufficient support to the inner wall of the roller, thereby improving the stability of the roller during installation.

[0017] 2. This utility model, by providing a connecting screw at the side end of the connecting pipe and connecting screw holes at both the side ends of the connecting pipe and the movable pipe, allows the connecting screw to be screwed into the connecting screw hole, thus extending the movable pipe and the connecting pipe as a whole. Simultaneously, by combining this with insertion slots on the sides of both the first and second mounting plates, and insertion flexible posts on the side edge of the second mounting plate, the first and second mounting plates can be spliced ​​and extended after the insertion flexible posts are pushed into the corresponding insertion slots. This allows for adjustment of the number of pushing blocks and transmission blocks when installing rollers of different lengths, thereby ensuring sufficient installation stability for rollers of different sizes.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0024] Example 1: An adjustable roller mounting structure for a food packaging machine, see [link / reference] Figures 1 to 4 A support plate 11 is vertically fixedly installed on the top of the mounting base 1. A fixing plate 12 is fixedly installed on the top surface of the support plate 11. A movable tube 15 is slidably installed through the middle of the side of the fixing plate 12. An abutting arc plate 23 is equidistantly installed on the outside of the movable tube 15. The connecting mechanism includes a connecting screw 3. A connecting screw hole 31 is horizontally opened in the middle of the side of the movable tube 15 and the connecting tube 16 away from the fixing plate 12. The connecting screw 3 is horizontally fixedly installed in the middle of the side of the connecting tube 16 close to the fixing plate 12. The connecting screw hole 31 is provided with a thread that matches the outside of the connecting screw 3. The depth of the connecting screw hole 31 is designed so that after the connecting screw 3 is fully screwed in, the pushing block 21 on the outside of the connecting tube 16 and the pushing block 21 on the outside of the movable tube 15 remain at the same horizontal position.

[0025] Both the first mounting plate 22 and the second mounting plate 4 have insertion slots 41 on both sides. The second mounting plate 4 has horizontally fixed insertion flexible posts 42 on both sides near the first mounting plate 22. The diameter of the insertion flexible posts 42 is slightly larger than that of the insertion slots 41, and the insertion flexible posts 42 are made of rubber and have a certain degree of elasticity.

[0026] When installing and using the rollers for the packaging machine, align the connecting screw 3 on the side of the connecting pipe 16 with the connecting screw hole 31 on the side of the movable pipe 15, and rotate the connecting pipe 16 clockwise until the connecting screw 3 is fully screwed into the connecting screw hole 31. At this time, the pushing block 21 on the outside of the connecting pipe 16 and the pushing block 21 on the outside of the movable pipe 15 are at the same horizontal position to ensure the continuity of subsequent power transmission. At the same time, according to the roller length requirements, align the insert flexible posts 42 on both sides of the second mounting plate 4 with the insertion grooves 41 on the side of the first mounting plate 22, and apply a certain pressure to squeeze the elastic rubber insert flexible posts 42 into the insertion grooves 41. Since the diameter of the insert flexible posts 42 is slightly larger than that of the insertion grooves 41, a tight fit can be formed to complete the splicing of the first mounting plate 22 and the second mounting plate 4, thereby extending the overall length of the transmission components.

[0027] Several sets of connecting bolts 28 are equidistantly inserted on the top side of the abutting arc plate 23, and the bottom end of the connecting bolts 28 is screwed into the top of the first mounting plate 22 by threads, which can realize the disassembly and replacement of the abutting arc plate 23, thereby ensuring the applicability adjustment of the length and side curvature of the abutting arc plate 23.

[0028] To address the difference in the curvature of the inner wall of the roller, the mating arc plate 23 is replaced by disassembling and replacing it. The connecting bolt 28 on the top side of the mating arc plate 23 is unscrewed, and the original mating arc plate 23 is removed from the top of the first mounting plate 22. A new mating arc plate 23 that matches the curvature of the inner wall of the roller to be installed is then replaced. The connecting bolt 28 is then tightened again to firmly fix the mating arc plate 23 on the first mounting plate 22, ensuring that the arc plate can fully fit against the inner wall of the roller during the subsequent mating process.

[0029] For details, see Figures 1 to 4 A protective circular frame 13 is fixedly installed on the side of the fixed plate 12 away from the connecting pipe 16. An electric push rod 14 is fixedly installed at the middle of the outer wall of the protective circular frame 13. The side end of the electric push rod 14 is fixedly connected to the outer wall of the movable pipe 15. Under the driving action of the electric push rod 14, the movable pipe 15 can pass through the side of the fixed plate 12 and move into the interior of the protective circular frame 13. The connecting pipe 16 is detachably installed on the side end of the movable pipe 15 through a connecting mechanism.

[0030] Further, see Figures 1 to 4 The pushing mechanism includes a pushing block 21 and a transmission block 24. Several sets of connecting blocks 2 are fixedly installed at equal intervals on the outer walls of the movable tube 15 and the connecting tube 16. The pushing block 21 is fixedly installed on the side of the connecting block 2 away from the movable tube 15. Several sets of transmission blocks 24 are fixedly installed at equal intervals on the side of the first mounting plate 22 and the second mounting plate 4 close to the movable tube 15. The vertical cross-sections of the pushing block 21 and the transmission block 24 are both trapezoidal. In the use state, the pressing arc plate 23 will be fully opened and fit against the inner wall of the roller under the action of the two sets of transmission blocks 24 and the pushing block 21, thereby fixing the roller. In the non-use state, when the roller to be installed is moved away from the outside of the pressing arc plate 23, the pressing arc plate 23 is in a non-use state. Under the limiting action of the guide frame 25, the pressing arc plate 23 will not completely detach from the surface of the entire device, thus not affecting the subsequent normal use.

[0031] The guiding mechanism includes guide frames 25. Four sets of guide frames 25 are fixedly installed at equal intervals on the side of the fixed plate 12. A first mounting plate 22 is slidably installed on the side of the guide frame 25. The side of the first mounting plate 22 away from the movable tube 15 is connected to the outer wall of the abutting arc plate 23. A second mounting plate 4 is detachably installed on the side of the first mounting plate 22. A guide slider 26 is fixedly installed on the side of the first mounting plate 22 close to the fixed plate 12. A guide groove 27 is opened inside the guide frame 25, and the guide slider 26 is slidably installed inside the guide groove 27. The cross-sections of the guide groove 27 and the guide slider 26 are both T-shaped.

[0032] After disassembling and replacing the clamping arc plate 23, the required conveying roller can be fitted onto the outer wall of the clamping arc plate 23. Then, the electric actuator 14 is opened via an external controller, and the electric actuator 14 begins to operate. Its side end is fixedly connected to the outer wall of the movable tube 15. Driven by the electric actuator 14, the movable tube 15 moves horizontally along the through hole on the side of the fixed plate 12, and can then move into the protective circular frame 13. The protective circular frame 13 protects the movable tube 15 from movement, preventing interference from external impurities. During movement, the connecting blocks 2, which are fixedly installed at equal intervals on their outer sides, drive the pushing block 21 to move horizontally in sync. As the pushing block 21 continues to move, the inclined surface of its trapezoidal vertical section gradually contacts the inclined surface of the transmission block 24 on the side near the movable tube 15 of the first mounting plate 22 and the spliced ​​second mounting plate 4. Since both the pushing block 21 and the transmission block 24 are trapezoidal vertical section designs, during the continuous horizontal movement of the pushing block 21, a lateral pushing force is generated on the transmission block 24. This force is then combined with the guide on the side of the first mounting plate 22 near the fixed plate 12. The slider 26 is fitted into the T-shaped guide groove 27 inside the guide frame 25. Under the action of lateral pushing force, the guide slider 26 slides linearly along the guide groove 27, driving the first mounting plate 22 and the top fixed abutting arc plate 23 to move synchronously away from the movable tube 15. Because the four sets of guide mechanisms are equidistantly distributed, the four sets of abutting arc plates 23 move outward synchronously under the guidance of the guide slider 26 and the guide groove 27, gradually reducing the distance with the inner wall of the roller. As the electric actuator 14 continues to drive the movable tube 15 to move, the push block 2... As the contact area between the push block 21 and the transmission block 24 increases, the lateral pushing force gradually increases until the outer wall of the pressing arc plate 23 is completely in contact with the inner wall of the roller. At this time, the electric push rod 14 stops operating, and the push block 21 and the transmission block 24 maintain a tight contact. The push block 21 transmits a continuous and stable supporting force to the first mounting plate 22 through the transmission block 24, thereby enabling the pressing arc plate 23 to apply a uniform and sufficient pressing force to the inner wall of the roller, firmly fixing the roller to the mounting structure and preventing the roller from shaking or shifting in subsequent food packaging operations.

Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.
