Description

Technical Field

[0001] This utility model relates to the technical field of ton bag production equipment, and in particular to a winding and cutting component and a ton bag base fabric winding system. Background Technology

[0002] The production process of ton bags begins with the production of the ton bag base fabric. This base fabric is then processed into ton bags through printing, cutting, and sewing. During the production of the ton bag base fabric, a winding device is required for winding. After one winding drum is completed, it needs to be cut and a new winding drum is used for subsequent winding, and this process is repeated. In existing technologies, winding systems typically use a pallet positioned below the cut point of the ton bag base fabric and a cutting blade positioned above it to achieve cutting. The cutting blade is usually driven up and down by a telescopic actuator. When it moves downward, it presses the ton bag base fabric against the pallet, and then continues to move to cut the ton bag base fabric. Usually, to ensure smooth cutting, pressure strips are installed on both sides of the cutting blade to press the ton bag base fabric tightly on both sides. This prevents the ton bag base fabric from being misaligned, which could negatively affect the cutting process. However, in actual operation, the downward-facing side of the ton bag base fabric is usually printed with patterns and text, and may not be completely dry. After being pressed down, the patterns and text come into direct contact with the pallet, which may result in large areas of defacement of the patterns and text near the cut point of the ton bag base fabric. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a winding and cutting assembly, which solves the problem that patterns and text may be heavily defaced near the cut edge of the ton bag base fabric in existing technologies.

[0004] According to an embodiment of this utility model, a winding and cutting assembly includes an upper top plate and a support plate located below the upper top plate. A cutting blade that moves up and down is installed below the support plate. A horizontal frame for the cutting blade to pass through is provided on the support plate. The support plate also has recessed receiving grooves located on both sides of the horizontal frame and parallel to the horizontal frame. An upper top strip is provided in each of the two receiving grooves. A magnetic attractor is provided on the upper top strip. An electromagnet is provided on the upper top plate. When the electromagnet is energized, it can attract the magnetic attractor in the receiving groove upwards to abut against the upper top plate. The cutting blade is located below the support plate and lifts upwards to cut during cutting. This avoids the bottom side of the ton bag base fabric from directly contacting the support plate. The contact area between the upper top strip and the ton bag base fabric is relatively smaller, thus preventing large-area defacement of patterns and text. This solves the problem in the prior art where patterns and text near the cut point of the ton bag base fabric may appear with large-area defacement.

[0005] Furthermore, a mounting bracket is fixedly connected to the pallet, and a telescopic actuator is mounted on the mounting bracket. The cutting blade is connected to the telescopic actuator to drive it to move up and down.

[0006] Furthermore, the bottom surface of the upper top plate is recessed with a mounting groove, and the electromagnet is installed in the mounting groove with the electromagnet and the upper top plate having a flush bottom surface.

[0007] Furthermore, magnetic suction components are fixedly connected to both ends of the top strip, and guide slide rods are fixedly connected between both ends of the receiving groove and the top plate, with the guide slide rods located on both sides of the mounting groove. The magnetic suction components are provided with sliding holes and are slidably sleeved on the guide slide rods through the sliding holes.

[0008] Furthermore, the electromagnets include a pair located directly above the two receiving slots, and both electromagnets are offset from the cutting blade in the vertical direction.

[0009] Furthermore, the bottom surface of the top plate is recessed and has an insertion groove located between the two electromagnets, and the cutting blade includes a blade edge that can partially insert into the insertion groove.

[0010] Furthermore, the cutting edge has an inverted V-shaped structure.

[0011] Furthermore, the thickness of the top strip is 1-3mm.

[0012] According to an embodiment, a ton bag base fabric winding system including the above-described winding and cutting assembly is also provided.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] A cutting blade is installed below the pallet. The cutting blade moves up and down through the horizontal frame to cooperate with the top plate to cut the bag. This avoids the bottom side of the ton bag base fabric from directly contacting the pallet during cutting. At the same time, the contact area between the top strip used to hold the ton bag base fabric and the ton bag base fabric is relatively smaller, so it will not cause large-area defacement of patterns and text. This solves the problem of large-area defacement of patterns and text near the cut of the ton bag base fabric in the prior art. Attached Figure Description

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0025] In an exemplary implementation, such as Figure 1-6As shown, this embodiment provides a ton bag base fabric winding system, which includes a winding and cutting assembly. The winding and cutting assembly is located in front of the winding drum and is used to cut the ton bag base fabric 1 after the winding drum is completed. The winding and cutting assembly includes an upper top plate 2 and a support plate 3 located below the upper top plate 2. The ton bag base fabric 1 passes between the upper top plate 2 and the support plate 3, and does not contact the support plate 3 or the upper top plate 2 during normal winding. A mounting frame 4 is also fixedly connected to the lower plate surface of the support plate 3. A telescopic driver 5 is also installed on the mounting frame 4. As in the prior art, the telescopic driver 5 can be a cylinder. The telescopic driver 5 has an upwardly extending output end and the output end is connected to a cutting blade 6. The cutting blade 6 moves up and down under the drive of the telescopic driver 5. At the same time, a horizontal frame 7 is provided on the support plate 3 for the cutting blade 6 to pass through. The ton bag base fabric 1 passes through the horizontal frame 7. When cutting is required, the telescopic driver 5 operates to make the cutting blade 6 move upward through. The fabric is cut by passing through the horizontal frame 7 and contacting the base fabric 1 of the ton bag. To ensure smooth cutting, the pallet 3 is recessed with receiving grooves 8 on both sides of the horizontal frame 7 and parallel to the horizontal frame 7. Each receiving groove 8 has an upper top bar 9 with a magnetic suction element 10 on it. An electromagnet 11 is installed on the upper top plate 2. When the electromagnet 11 is energized, it can pull the magnetic suction element 10 in the receiving groove 8 upward to press against the upper top plate 2. This allows the electromagnet 11 to be energized during cutting. Then, the upper top bar 9 moves upward to press the portion of the base fabric 1 of the ton bag on both sides of the horizontal frame 7 against the upper top plate 2. Then, the telescopic driver 5 is activated to cut. This cutting method prevents the base fabric 1 of the ton bag from contacting the pallet 3. At the same time, the upper top bar 9 and the base fabric 1 of the ton bag have a smaller contact area, so it will not cause large-area defacement of patterns and text. This solves the problem of large-area defacement of patterns and text near the cut of the base fabric 1 of the ton bag in the prior art.

[0026] like Figure 1-6 As shown, in a further embodiment, the bottom surface of the upper top plate 2 is recessed with an installation groove. The installation groove can be a pair located on both sides of the cutting blade 6. An electromagnet 11 is installed in both installation grooves, and both electromagnets 11 and the upper top plate 2 have a flat bottom surface. The electromagnets 11 are not protruding, and the cutting blade 6 is located between the two electromagnets 11, so as not to cause adverse effects on the electromagnets 11. In a more detailed embodiment, an insertion groove 12 can be provided between the two installation grooves for the cutting blade 6 to partially insert, so that the ton bag base fabric 1 can be cut smoothly. The upper end of the cutting blade 6 is a blade edge 13 with an inverted V-shape structure. The insertion groove 12 can also be an inverted V-shape structure, but the width and length of the lower end of the insertion groove 12 are slightly larger, so that the upper end of the blade edge 13 can better insert and achieve cutting.

[0027] like Figure 1-6As shown, magnetic suction components 10 are fixedly connected to both ends of the upper top strip 9. Guide slide rods 14 are fixedly connected between both ends of the receiving groove 8 and the upper top plate 2, and the guide slide rods 14 are located on both sides of the mounting groove. The magnetic suction component 10 is provided with sliding holes and is slidably sleeved on the guide slide rod 14 through the sliding holes. The guide slide rod 14 provides vertical sliding guidance for the magnetic suction component 10, so that it can slide up and down along the guide slide rod 14. Specifically, after the electromagnet 11 is energized (the attraction force generated by the electromagnet 11 is large enough to attract the magnetic suction component 10 and the upper top strip 9), the magnetic suction component 10 is magnetically pulled upward, driving the upper top strip 9 upward, and finally pressing the ton bag base fabric 1 against the upper top plate 2 (at this time, the winding is paused). After cutting, replace the new take-up drum and continue. Then start the telescopic drive 5 to cut again, then lift the telescopic drive 5 down, then disconnect the electromagnet 11 and turn on the power. The magnetic suction part 10 slides down and returns to the receiving groove 8, and then the next round of winding operation can be carried out again. (There is a gap between the pallet 3 and the upper top plate 2. After cutting, the cut end of the base fabric can be pulled out in the winding direction through this gap, and then the next round of operation can be carried out.) In a further scheme, the upper top bar 9 can be a thin iron sheet, such as an iron sheet with a thickness of 1-3mm. After the electromagnet 11 is turned on, it can also generate a suction force on the upper top bar 9, and the weight of the upper top bar 9 is also small, so it can move upward smoothly.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
