Abstract
Description
Technical Field
[0001] This utility model relates to a production line for packaging bags such as cement bags and chemical bags, and in particular to a feeding and correction mechanism. Background Technology
[0002] The production of packaging bags such as cement bags and chemical bags usually uses paper rolls as the core raw material and is completed through multiple processes such as gluing, cutting, and bag making. Among these processes, the placement and replacement of paper roll raw materials are important links that affect production efficiency and operational safety.
[0003] Existing simple support structures are relatively basic, typically only providing basic support for paper rolls. However, the position of each paper roll installed on the production equipment is often difficult to maintain precisely. For example, the previous paper roll may be exactly in the middle of the equipment, but after replacing it with the next roll, it may be 3 centimeters to the left or have other offsets. This uncertainty in position can lead to problems in subsequent production processes, such as printing patterns and thermoforming, resulting in misaligned patterns and uneven thermoforming joints. This reduces the product qualification rate and increases production costs. Summary of the Invention
[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a feeding and correction mechanism.
[0005] The technical solution adopted by this utility model to solve its technical problem is:
[0006] A feeding and correction mechanism includes a base, on which a raw material support that is driven to slide left and right by a correction drive motor is installed. The raw material support is provided with a first slot for placing paper roll raw material. A U-shaped seat that can be adjusted left and right is installed on the base. The paper of the paper roll raw material passes through the U-shaped seat. An inspection device for detecting the position of the paper is provided inside the U-shaped seat.
[0007] A fixing rod is installed on one side of the base, and a connector that can be adjusted to the left and right is installed on the fixing rod. The "U"-shaped seat is fixedly installed on the connector.
[0008] The base is equipped with symmetrical slide rails, and the raw material support is equipped with a slider corresponding to the slide rails. The slider is slidably mounted on the slide rails.
[0009] A braking base rod is installed on the front side of the raw material support, and a braking roller driven by a second cylinder to move upward or downward is installed above the braking base rod. The paper of the paper roll raw material passes between the braking base rod and the braking roller.
[0010] The braking roller is densely covered with several rows of flexible columns.
[0011] The brake base rod is provided with guide posts on both sides, and the brake roller is provided with through holes corresponding to the guide posts, with the guide posts passing through the through holes.
[0012] A mounting column is installed on one side of the raw material support. A slidable positioning component is provided on the mounting column. The positioning component is provided with a positioning slot for positioning the center roller of the paper roll raw material. The center roller of the paper roll raw material is provided with an annular groove corresponding to the positioning slot. The positioning slot is engaged in the annular groove.
[0013] A lead screw is provided inside the mounting column, and a lead screw nut is installed on the lead screw. Slotted holes are provided on both sides of the mounting column. A connecting part extending from the slotted hole is fixed to the lead screw nut, and the connecting part is fixedly connected to the positioning member.
[0014] A hinged roller is installed on the rear side of the raw material support. Both ends of the hinged roller are rotatably mounted with hinged components driven to rotate by a third cylinder. An auxiliary support is rotatably mounted on the side of the hinged component away from the third cylinder. The auxiliary support is provided with a second slot for placing the center roller of the paper roll raw material.
[0015] The hinge assembly includes rotating blocks on both sides and a connecting rod fixedly connected to the rotating blocks. The two rotating blocks are respectively installed on both sides of the hinge roller. Limiting notches are provided on both sides of the raw material support, and the end of the connecting rod is inserted into the limiting notch.
[0016] The beneficial effects of this utility model are as follows: A feeding and correction mechanism includes a base, on which a raw material support that is driven to slide left and right by a correction drive motor is installed. The raw material support is provided with a first slot for placing paper roll raw materials. A U-shaped seat that can be adjusted left and right is installed on the base. The paper of the paper roll raw materials passes through the U-shaped seat. An inspection device for detecting the position of the paper is provided inside the U-shaped seat. When the inspection device does not detect the paper, the correction drive motor controls the raw material support to move towards the inspection device until the inspection device detects the paper. This ensures that each paper roll is in a stable working position during the production process, greatly improves the consistency of the position of the paper roll raw materials, saves the time of operators manually adjusting the position of the paper roll, reduces production interruptions, and makes the production process more continuous and smooth.

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0027] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.
[0028] The following describes some embodiments of the present invention with reference to the accompanying drawings.
[0029] Reference Figure 1-8 A feeding and correction mechanism includes a base 1, on which a raw material support 3 is mounted, which is driven to slide left and right by a correction drive motor 2. The raw material support 3 is provided with a first slot 4 for placing paper roll raw materials. A U-shaped seat 5 with adjustable installation position is mounted on the base 1. The paper of the paper roll raw material passes through the U-shaped seat 5. An inspection device for detecting the paper position is provided inside the U-shaped seat 5 (the inspection device is one of photoelectric sensors, laser sensors, etc.). When the inspection device does not detect paper, the raw material support 3 is controlled by the correction drive motor 2 to move towards the inspection device until the inspection device detects paper. This ensures that each paper roll is in a stable working position during the production process, greatly improves the consistency of the paper roll raw material position, saves the time of operators manually adjusting the paper roll position, reduces production interruptions, and makes the production process more continuous and smooth.
[0030] A fixing rod 7 is installed on one side of the base 1. A connector 8 with an adjustable left-right installation position is installed on the fixing rod 7. The "U"-shaped seat 5 is fixedly installed on the connector 8. The connector 8 consists of two parts: a hollow tube for passing through the fixing rod 7 and an installation part for fixing to the "U"-shaped seat 5. A fixing screw is installed on the hollow tube. When the fixing screw is loosened, the fixing screw separates from the fixing rod 7, and the hollow tube can slide on the fixing rod 7 to achieve the left-right adjustment effect. After the position adjustment is completed, the connector 8 is fixed by tightening the fixing screw until it abuts against the fixing rod 7.
[0031] The base 1 is equipped with symmetrical slide rails 9, and the raw material support 3 is equipped with a slider corresponding to the slide rails 9. The slider is slidably mounted on the slide rails 9, thereby improving the sliding stability of the raw material support 3.
[0032] Furthermore, the raw material support 3 is provided with a clearance opening corresponding to the slide rail 9, and the slide rail 9 passes through the clearance opening. When the raw material support 3 slides, the clearance opening and the slide rail 9 slide relative to each other simultaneously.
[0033] A braking base rod 10 is installed on the front side of the raw material support 3. A braking roller 12, driven by a second cylinder 11, is installed above the braking base rod 10. The paper of the paper roll passes between the braking base rod 10 and the braking roller 12. When a problem occurs in the production line and it needs to be stopped, the second cylinder 11 drives the braking roller 12 to press down, thereby gradually reducing the speed of the paper until it stops. At the same time, the paper behind the braking roller 12 is kept taut. Since the paper roll loses the tension of the production line traction roller, the paper roll will also gradually decelerate. At that time, a portion of the paper will still be output. The worker can then rotate the paper roll in the opposite direction to rewind the loosened paper back into the paper roll.
[0034] Furthermore, the braking roller 12 is densely covered with several arranged flexible columns 13. The paper is stopped by the pressure between the flexible columns 13 and the braking base rod 10. Since the flexible columns 13 have a certain degree of flexibility, they can play a buffering role and prevent the paper from being directly torn.
[0035] Furthermore, guide posts 14 are provided on both sides of the braking base rod 10, and through holes are provided on the braking roller 12 corresponding to the guide posts 14. The guide posts 14 are inserted into the through holes. On the one hand, this improves the stability of the movement of the braking roller 12, and on the other hand, it improves the installation strength of the braking roller 12, so as to avoid the friction between the paper and the flexible column 13 causing the braking roller 12 to deviate when braking, thereby reducing the deceleration effect.
[0036] A hinge roller 22 is installed on the rear side of the raw material support 3. A hinge assembly 24 driven to rotate by a third cylinder 23 is rotatably installed at both ends of the hinge roller 22. An auxiliary support 25 is rotatably installed on the side of the hinge assembly 24 away from the third cylinder 23. A second bayonet 26 for placing the center roller of the paper roll raw material is provided on the auxiliary support 25.
[0037] During initial production, a new roll of paper material is placed on the first latch 4. When the paper roll material decreases to a certain level, the worker manually swings the auxiliary support 25, causing the second latch 26 to engage with the center roller of the paper roll material. At this time, the third cylinder 23 is activated, causing the hinge assembly 24 to rotate around the hinge roller 22. Through the lever structure, the auxiliary support 25 is moved upward, thereby lifting the paper roll material that is being produced normally. The worker then swings the auxiliary support 25 again, causing the center roller of the paper roll material to move away from above the first latch 4. The third cylinder 23 is activated again, causing the hinge assembly 24 to rotate in the opposite direction around the hinge roller 22, thereby removing the paper roll material. The auxiliary support 25 serves as the output end of the production material (e.g., Figure 3 As shown in B), at this point, the new paper roll material can be installed on the first bayonet 4 using a device such as a crane arm (e.g., Figure 3 As shown in A), after the paper roll material of the auxiliary support 25 is completely consumed, a new paper roll material can be connected to the production line, thereby greatly improving the efficiency of paper roll replacement.
[0038] Furthermore, a first bearing 30 is installed in the first bayonet 4, and a second bearing 31 is installed in the second bayonet 26, which effectively improves the smoothness of paper roll material feeding.
[0039] The hinge assembly 24 includes two rotating blocks 27 on both sides and a connecting rod 28 fixedly connected to the rotating blocks 27. The two rotating blocks 27 are respectively installed on both sides of the hinge roller 22. The two rotating blocks 27 are fixedly connected by the connecting rod 28, thereby achieving the effect of synchronous rotation of the two rotating blocks 27. The two rotating blocks 27 are respectively installed on both sides of the hinge roller 22.
[0040] Furthermore, the raw material support 3 has limiting notches 29 on both sides, and the end of the connecting rod 28 is inserted into the limiting notch 29. When the connecting rod 28 is located at the lowermost side of the limiting notch 29, it is the initial position of the auxiliary support 25 (e.g., Figure 5 (As shown in C); the connecting rod 28 is located at the middle section of the limiting notch 29, at which time the second latch 26 engages with the center roller of the paper roll material (as shown in C). Figure 6 (As shown in D); the connecting rod 28 is located at the uppermost side of the limiting notch 29. At this time, the auxiliary bracket 25 lifts the paper roll material away from the first bayonet 4 (as shown in D). Figure 7 (As shown in E in the figure).
[0041] Furthermore, the third cylinder 23 is rotatably mounted on the raw material support 3 via the mounting bracket 32. When the worker swings the auxiliary support 25, the mounting bracket 32, the third cylinder 23, the rotating block 27, and other components will rotate accordingly. At this time, the third cylinder 23 will not start. When the second latch 26 is engaged with the center roller of the paper roll raw material, the third cylinder 23 starts, which can push the auxiliary support 25 up through the lever principle, thereby lifting the paper roll raw material.
[0042] The end of the auxiliary support 25 extends below the hinge roller 22. When the auxiliary support 25 is in the initial position, the end of the auxiliary support 25 abuts against the hinge roller 22. At this time, the connecting rod 28 is located at the lowest side of the limiting notch 29. The connecting rod 28 can be regarded as a fixing rod. The auxiliary support 25 can rotate downward around the connecting rod 28. When the end of the auxiliary support 25 abuts against the hinge roller 22, the auxiliary support 25 cannot continue to move downward, thereby fixing the auxiliary support 25. When the auxiliary support 25 is used as the output end of the production raw material, it also has sufficient stability.
[0043] A mounting column 15 is installed on one side of the raw material support 3. A slidable positioning member 16 is provided on the mounting column 15. A positioning slot 17 for positioning the center roller of the paper roll raw material is provided on the positioning member 16. The center roller of the paper roll raw material is provided with an annular groove 18 corresponding to the positioning slot 17. The positioning slot 17 is engaged in the annular groove 18.
[0044] The mounting post 15 is provided with a lead screw 19, which can be driven by a motor, hand crank, or other means. A lead screw nut is installed on the lead screw 19. The mounting post 15 has strip holes 21 on both sides. The lead screw nut is fixed with a connecting part 20 extending from the strip hole 21. The connecting part 20 is fixedly connected to the positioning member 16.
[0045] Each roll of paper stock has a different winding position during production. For example, when one roll of paper stock is wound up, the paper is in the middle of the center roller, while when another roll of paper stock is wound up, the paper is 5 centimeters to the left of the center roller. Therefore, even if the paper stock is installed in the same position in this product (actually, the center roller of the paper roll is installed in the same position), the paper output position may still be different.
[0046] Therefore, in this product, when the paper roll material is reduced to a certain extent and is received by the auxiliary support 25, the first bayonet 4 is in an empty state. The new paper roll material is hoisted to the top of the material support 3 by the crane arm and other equipment. The position of the center roller of the paper roll material is manually adjusted by the worker so that the positioning bayonet 17 is paired with the annular groove 18. Then the crane arm can be removed. At this time, by rotating the lead screw 19, the positioning part 16 is moved through the lead screw nut, thereby moving the center roller to achieve the pre-adjustment of the paper roll material output position. Subsequently, when the paper roll material is connected to the production line, the inspection device performs higher precision detection, and the material support 3 is moved by the correction drive motor 2 to achieve fine adjustment.
