Description

TECHNICAL FIELD

[0001] The utility model relates to food packaging technical field especially a kind of continuous bag folding machine. BACKGROUND

[0002] In food packaging industry, continuous bag folding machine is a commonly used equipment, and the continuous bag folding machine is used to connect and fold multiple packaged foods, which is used to fold the continuous bag products according to specific requirements, so as to facilitate subsequent packaging, storage and transportation.

[0003] According to the search, the Chinese patent with the publication number CN104843250B provides a folding device for continuous bags, which realizes the folding of continuous bags by using a rotating mechanism. The folding efficiency is improved by directly placing the continuous bags into the rotating mechanism. The two side plates of the dividing plate bear each product bag of the continuous bag, avoiding mutual interference between the product bags.

[0004] However, during use, it is found that when folding continuous bag product bags of different sizes, the length and angle adjustment range of the dividing plate is limited, and the adjustment is relatively cumbersome, which is difficult to adapt to the folding of continuous bag products with larger or smaller sizes, and it is difficult to meet the diversified production needs, resulting in problems such as inaccurate folding and non-fitting packaging when facing continuous bag foods of different sizes, affecting product quality and packaging effect. UTILITY MODEL CONTENT

[0005] In view of the deficiencies of the prior art, the utility model provides a continuous bag folding machine, which is suitable for continuous bag foods of different sizes, meets the diversified production needs, improves the folding accuracy, avoids the problems of inaccurate folding and non-fitting packaging, and improves the product quality and packaging effect.

[0006] To solve the above technical problems, the utility model provides the following technical scheme: a continuous bag folding machine, comprising a frame, the top surface of the frame is symmetrically provided with two clamping blocks, the inner end of the clamping block is rotatably connected with a roller shaft, the upper end of the frame is fixedly connected with a fixed block, the middle bottom surface of the fixed block is fixedly provided with a supporting block, the lower end of the supporting block is rotatably connected with a sleeve ring, the inside of the sleeve ring is slidably connected with a circular shaft, one end of the circular shaft is fixedly provided with a folding assembly.

[0007] The folding assembly comprises an adjusting block, the front wall middle part of the adjusting block is fixedly connected with a circular shaft, the adjusting block is rotatably connected with a bidirectional screw rod, the outer wall of the adjusting block is symmetrically provided with two through grooves, the inside of the through groove is slidably connected with a sliding block, the two sliding blocks are respectively connected with the bidirectional screw rod through threaded holes, and the rear wall of the sliding block is fixedly provided with a lever.

[0008] Preferably, a first servo motor is mounted on the outer wall of one end of the adjusting block via a mounting base, and the output shaft of the first servo motor is coaxially connected to a bidirectional lead screw.

[0009] The above technical solution uses the output shaft of the first servo motor to drive the bidirectional lead screw to rotate along the adjusting block, thereby causing the slider to move within the through slot and thus adjusting the lever spacing.

[0010] Preferably, two first cylinders are mounted on the rear wall of the frame via mounting bases, and a connecting block is fixedly provided at the outer end of the clamping block, with the piston rod of the first cylinder being fixedly connected to the connecting block.

[0011] Through the above technical solution, the first cylinder pushes the connecting block to move the clamping block by extending and retracting the piston rod, thereby further adjusting the clamping position and force of the packaged food to meet the needs of packages of different shapes and sizes.

[0012] Preferably, the inner wall of the collar is fixed with a protrusion, the outer wall of the round shaft is provided with a groove, the protrusion and the groove are engaged, and a toothed ring is sleeved on the outer wall of the collar.

[0013] Preferably, a second servo motor is mounted on the outer wall of the support block via a mounting base, and a gear is sleeved on the output shaft of the second servo motor, the gear meshing with a gear ring.

[0014] Through the above technical solution, the gear is driven to rotate by the second servo motor, which meshes with the gear ring to drive the collar to rotate. Through the cooperation of the protrusion and the groove, the round shaft rotates, which drives the adjusting block, the slider and the lever to rotate synchronously.

[0015] Preferably, a movable block is slidably connected to the outer peripheral wall of the fixed block, and a pusher is fixedly provided on the bottom surface of the movable block.

[0016] Preferably, a circular block is fixed on the circular shaft, the circular block is located inside the lower end of the push block, and the outer peripheral wall of the circular block and one end of the circular shaft are respectively rotatably connected to the push block.

[0017] Preferably, a second cylinder is mounted on the top surface of the fixed block via a mounting base, and the piston rod of the second cylinder is fixedly connected to the moving block.

[0018] Through the above technical solution, the piston rod of the second cylinder extends and retracts, driving the moving block and the pushing block, which in turn pushes the circular block and the circular shaft to realize the movement of the folding component.

[0019] The beneficial effects of this utility model are:

[0020] The packaged food is placed between two clamping blocks. The rollers connected to the inner ends of the clamping blocks facilitate the placement and adjustment of the package's position. When different sizes of packages need to be folded, the two sliders move relative to each other or away from each other along the through groove by rotating the bidirectional lead screw, changing the distance between the two levers to accommodate the folding requirements of different sized packages. After adjusting the lever positions, the packaged food is moved to the appropriate position. The rotating shaft drives the adjusting block to rotate, causing the sliders and levers to rotate synchronously. The two levers contact the package and push it to fold, completing the folding operation. After the folding operation is completed, the levers separate from the package and move back to the ready position for the next folding operation. This system adapts to different sizes of packaged food, improves folding accuracy, avoids problems such as inaccurate folding and non-fitting packaging, and enhances product quality and packaging effect.

[0021] The output shaft of the first servo motor drives the bidirectional lead screw to rotate along the adjusting block. At the same time, the first cylinder pushes the connecting block to move the clamping block through the extension and retraction of the piston rod, further adjusting the clamping position and force of the packaged food, ensuring the stability of the package during the folding process, and avoiding inaccurate folding caused by the shaking of the package.

[0022] Once the lever position is adjusted, the packaged food is moved to the appropriate position. The output shaft of the second servo motor drives the gear to rotate. The gear meshes with the gear ring, causing the collar to rotate. This causes the protrusion to drive the round shaft to rotate through the groove. The rotation of the round shaft drives the adjusting block fixed to it to rotate, which in turn causes the slider and lever to rotate synchronously. The two levers contact the package and push it to fold. After the folding operation is completed, the levers separate from the package, and the second servo motor rotates in the opposite direction to reset. This allows the levers to move to the ready position for the next folding operation. This achieves control over the rotation angle and speed of the levers, making the folding action more accurate and standardized, and improving the folding effect of the package.

[0023] When the packaged food is placed and the lever is adjusted to the appropriate position for folding, the piston rod of the second cylinder extends and retracts, causing the moving block to slide along the outer periphery of the fixed block. The push block moves along with the moving block, driving the round block and the round shaft to move synchronously, thus moving the folding assembly. The lever is inserted from the folded sides of the packaged food. After the second servo motor drives the round shaft to rotate, causing the lever to rotate and complete the package folding operation, the piston rod of the second cylinder extends and retracts in the opposite direction, causing the push block to drive the round shaft and the lever to move in the opposite direction. This allows the lever to exit from the folded package and return to its initial position, preparing for the next folding operation. This makes the package folding process more flexible, and it is easier to adjust the position of the lever when dealing with packaged food of different lengths and shapes, ensuring accurate folding of each part of the package. This improves the adaptability to different packaged products and increases production efficiency. Attached Figure Description

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Example 1: As Figure 1 , Figure 2 and Figure 3 As shown, this embodiment provides a continuous bag folding machine, including a frame 1. The top surface of the frame 1 is symmetrically provided with two clamping blocks 2. The inner end of the clamping block 2 is rotatably connected to a roller shaft 3. The upper end of the frame 1 is fixedly connected to a fixing block 4. The bottom surface of the middle part of the fixing block 4 is fixedly provided with a support block 5. The lower end of the support block 5 is rotatably connected to a collar 6. A round shaft 7 is slidably connected inside the collar 6. One end of the round shaft 7 is fixedly provided with a folding component 8.

[0031] The folding assembly 8 includes an adjusting block 801. The middle of the front wall of the adjusting block 801 is fixedly connected to the round shaft 7. A bidirectional lead screw 802 is rotatably connected to the adjusting block 801. The outer wall of the adjusting block 801 has two through slots 803 with a symmetrical structure. A slider 804 is slidably connected inside the through slot 803. The two sliders 804 are threadedly connected to the bidirectional lead screw 802 through threaded holes. A lever 806 is fixedly provided on the rear wall of the slider 804.

[0032] A first servo motor 805 is mounted on the outer wall of one end of the adjusting block 801 via a mounting base. The output shaft of the first servo motor 805 is coaxially connected to the bidirectional lead screw 802. The output shaft of the first servo motor 805 drives the bidirectional lead screw 802 to rotate along the adjusting block 801, thereby driving the slider 804 to move in the through groove 803, thereby realizing the adjustment of the distance of the lever 806.

[0033] Two first cylinders 9 are mounted on the rear wall of frame 1 via mounting bases. A connecting block 10 is fixedly provided at the outer end of clamping block 2. The piston rod of the first cylinder 9 is fixedly connected to the connecting block 10. The first cylinder 9 pushes the connecting block 10 to move the clamping block 2 by extending and retracting the piston rod, thereby further adjusting the clamping position and force of the packaged food to meet the needs of packages of different shapes and sizes.

[0034] A protrusion 11 is fixed on the inner wall of the collar 6, and a groove 12 is opened on the outer wall of the round shaft 7. The protrusion 11 and the groove 12 are engaged. A gear ring 13 is sleeved on the outer wall of the collar 6. A second servo motor 14 is mounted on the outer wall of the support block 5 through a mounting base. A gear 15 is sleeved on the output shaft of the second servo motor 14. The gear 15 meshes with the gear ring 13. The second servo motor 14 drives the gear 15 to rotate, which meshes with the gear ring 13 and drives the collar 6 to rotate. Through the cooperation of the protrusion 11 and the groove 12, the round shaft 7 is rotated, which drives the adjusting block 801, the slider 804 and the lever 806 to rotate synchronously.

[0035] Working principle: The packaged food is placed between two clamping blocks 2. The roller 3 connected to the inner end of the clamping block 2 facilitates the placement and adjustment of the package position. When different sizes of packages need to be folded, the two sliders 804 move relative to each other or away from each other along the through groove 803 by rotating the bidirectional screw 802, changing the distance between the two levers 806 to adapt to the folding requirements of different sizes of packaged food. After adjusting the position of the levers 806, the packaged food is moved to the appropriate position. The rotating of the round shaft 7 drives the adjusting block 801 to rotate, so that the sliders 804 and levers 806 rotate synchronously. The two levers 806 contact the package and push the package to fold, completing the folding operation. After the folding operation is completed, the levers 806 separate from the package and move to the preparation position for the next folding operation. This method adapts to different sizes of packaged food, meets diverse production needs, improves the accuracy of folding, avoids problems such as inaccurate folding and non-fitting packaging, and improves product quality and packaging effect.

[0036] The output shaft of the first servo motor 805 drives the bidirectional lead screw 802 to rotate along the adjusting block 801. At the same time, the first cylinder 9 pushes the connecting block 10 to move the clamping block 2 through the extension and retraction of the piston rod, further adjusting the clamping position and force of the packaged food, ensuring the stability of the package during the folding process, and avoiding the problem of inaccurate folding caused by the shaking of the package.

[0037] After the lever 806 is adjusted to the correct position, the packaged food is moved to the appropriate position. The output shaft of the second servo motor 14 drives the gear 15 to rotate. The gear 15 meshes with the gear ring 13, causing the collar 6 to rotate. This causes the protrusion 11 to drive the round shaft 7 to rotate through the groove 12. The rotation of the round shaft 7 drives the adjusting block 801, which is fixedly connected to it, to rotate. This causes the slider 804 and the lever 806 to rotate synchronously. The two levers 806 contact the package and push it to fold. After the folding operation is completed, the lever 806 separates from the package. The second servo motor 14 rotates in the opposite direction to reset, causing the lever 806 to move to the ready position for the next folding operation. This achieves control over the rotation angle and speed of the lever 806, making the folding action more accurate and standardized, and improving the folding effect of the package.

[0038] Example 2: Figure 1 , Figure 2 and Figure 4 As shown, based on Embodiment 1, a movable block 16 is slidably connected to the outer peripheral wall of the fixed block 4. A push block 17 is fixedly provided on the bottom surface of the movable block 16, and a circular block 18 is fixedly provided on the circular shaft 7. The circular block 18 is located inside the lower end of the push block 17. The outer peripheral walls of the circular block 18 and one end of the circular shaft 7 are respectively rotatably connected to the push block 17. A second cylinder 19 is installed on the top surface of the fixed block 4 through a mounting seat. The piston rod of the second cylinder 19 is fixedly connected to the movable block 16. The piston rod of the second cylinder 19 extends and retracts, driving the movable block 16 and the push block 17, thereby pushing the circular block 18 and the circular shaft 7 to realize the movement of the folding component 8.

[0039] In use, when the packaged food is placed and the lever 806 is adjusted to the appropriate position for folding, the piston rod of the second cylinder 19 extends and retracts, causing the moving block 16 to slide along the outer peripheral wall of the fixed block 4. The push block 17 moves together with the moving block 16, and the push block 17 drives the round block 18 and the round shaft 7 to move synchronously, moving the folding assembly 8. The lever 806 is inserted from the folded sides of the packaged food. After the second servo motor 14 drives the round shaft 7 to rotate, causing the lever 806 to rotate and complete the package folding operation, the piston rod of the second cylinder 19 extends and retracts in the opposite direction, causing the push block 17 to drive the round shaft 7 and the lever 806 to move in the opposite direction, thereby allowing the lever 806 to exit from the folded package and return to the initial position, preparing for the next folding operation. This makes the package folding process more flexible, and when faced with packaged foods of different lengths and shapes, it is easier to adjust the position of the lever 806 to ensure accurate folding of each part of the package, improving adaptability to different packaged products and increasing production efficiency.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
