Description

Technical Field

[0001] This utility model relates to the field of bar pack conveying technology, and in particular to a bar pack self-variable distance conveying mechanism. Background Technology

[0002] Currently, strip bag packaging machines on the market rely on their own gravity to freely convey the strip bags downwards after they are welded and formed. When the machine's operating speed increases, relying on the free fall of the strip bags can easily cause jamming, resulting in machine shutdown and affecting production efficiency.

[0003] As equipment operating speed increases and production efficiency improves, the frequency of strip feeding also increases. Free-fall motion is easily affected by factors such as the strip material, shape, static electricity, and airflow disturbances within the falling channel, causing uncontrollable deflection or tumbling of the strip during its descent. This phenomenon can easily cause the strip to jam in the conveyor channel, leading to equipment shutdown.

[0004] Therefore, a variable-pitch conveying mechanism for strip packages is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a variable-pitch conveying mechanism for bar packages, which can prevent the bar packages from getting stuck due to free fall during the conveying process, thus causing the equipment to stop.

[0008] The conveying roller and the adjusting roller are both rotatably mounted on the frame. They are arranged parallel to each other and have a gap between them. They are used to rotate in different directions along their respective rotation axes and to contact the strip package located in the gap. The rotation of the two rollers drives the strip package through the gap. The adjusting roller is used to move towards and away from the conveying roller.

[0009] The pull rod has its first end connected to the first end of the adjusting roller, and its second end extending beyond the conveying roller and located outside the conveying roller.

[0011] An elastic element is sleeved on the outer periphery of the pull rod, one end of the elastic element abuts against the limiting body, and the other end of the elastic element abuts against the frame near the conveyor roller;

[0012] The elastic element is used to: when the strip moves to the spacing, the strip abuts against the adjusting roller and moves away from the conveying roller, and the adjusting roller drives the pull rod to move synchronously, so that the elastic element is compressed and the spacing becomes larger.

[0013] Preferably, the frame includes a first support body and a second support body, wherein a first bag-clamping conveyor seat is connected to the first support body, and a second bag-clamping conveyor seat is connected to the second support body;

[0016] The two ends of the conveyor roller are respectively connected to the first bag-clamping conveyor seat and the second bag-clamping conveyor seat.

[0017] Preferably, the conveying roller and the adjusting roller are provided with corresponding rollers, which are used to contact the strip package.

[0018] Preferably, the pull rod includes a first rod and a second rod connected to each other, and the first rod and the second rod are set at an angle;

[0019] The first rod passes through the first bag-clamping conveyor seat or the second bag-clamping conveyor seat. Both first rods are located on the outer sides of both ends of the conveyor roller. The second rod is connected to the adjusting seat on the first bag-clamping conveyor seat or the adjusting seat on the second bag-clamping conveyor seat.

Detailed Implementation

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] It should be noted that the directional terms such as "upper end," "lower end," "left side," and "right side" mentioned below are defined based on the accompanying drawings in the instruction manual.

[0042] See attached document Figure 1 - Appendix Figure 9 The strip package self-variable pitch conveying mechanism includes a frame, a conveying roller 17, an adjusting roller 4, a pull rod 8, a limiting body 10, and an elastic element 9.

[0043] The frame includes a first support body 1 and a second support body 16. A first bag-clamping conveyor seat 2 is connected to the first support body 1, and a second bag-clamping conveyor seat 3 is connected to the second support body 16.

[0044] Understandably, the frame serves as the foundation for supporting other moving parts, providing stability and support. (See attached diagram.) Figure 1 The first support 1 and the second support 16 are arranged along the Y-axis direction, that is, the first support 1 and the second support 16 are arranged sequentially in the Y-axis direction.

[0045] Specifically, both the first support body 1 and the second support body 16 are L-shaped and symmetrical to each other. The first support body 1 is fixedly supported to the first bag-clamping conveyor seat 2 by bolts or other means, and the second support body 16 is also fixedly supported to the second bag-clamping conveyor seat 3 by bolts or other means. The first bag-clamping conveyor seat 2 and the second bag-clamping conveyor seat 3 are located at the two ends of the conveying mechanism, respectively.

[0046] The conveyor roller 17 and the adjusting roller 4 are both rotatably mounted on the frame, arranged parallel to each other with a gap between them. They are used to rotate in different directions along their respective axes of rotation, and also to contact the strips of bread located within the gap. The rotation of both rollers drives the strips of bread through the gap. The adjusting roller 4 is used to move towards and away from the conveyor roller 17. Both the conveyor roller 17 and the adjusting roller 4 are positioned between the first bag-clamping conveyor seat 2 and the second bag-clamping conveyor seat 3. The length direction of the conveyor roller 17 and the adjusting roller 4 is along the attached... Figure 1 The direction of the Y-axis in the coordinate system refers to the direction of the rotation axes of both the conveyor roller 17 and the adjusting roller 4. Figure 1 In the Y-axis direction, at the same time, the conveyor roller 17 and the adjusting roller 4 are also arranged along the X-axis direction, while the strip is conveyed downward along the Z-axis direction.

[0047] It is understandable that both the conveyor roller 17 and the adjusting roller 4 are cylindrical, and both can rotate in different directions along their respective axes.

[0048] Specifically, the conveyor roller 17 and the adjusting roller 4 are identical in size and dimensions. Since both the conveyor roller 17 and the adjusting roller 4 are cylindrical, when they rotate in opposite directions, the friction on their surfaces enables a pushing and conveying effect, thereby unidirectionally conveying the package.

[0049] Furthermore, the distance between the adjusting roller 4 and the conveying roller 17 is adjustable to accommodate strips of different thicknesses.

[0050] In some embodiments, during the actual conveying of the strip, the strip will abut against the conveyor roller 17 and the adjusting roller 4. When the thickness of the strip changes, it will push the adjusting roller 4 apart, causing the adjusting roller 4 to move, thereby passively increasing the distance between the adjusting roller 4 and the conveyor roller 17. However, it should be noted that the position of the conveyor roller 17 does not change during this process; only the adjusting roller 4 moves towards and away from the conveyor roller 17. Both the facing and moving away movements of the adjusting roller 4 are along the X-axis setting direction.

[0051] Specifically, the first bag-clamping conveyor 2 and the second bag-clamping conveyor 3 are each provided with an adjusting seat 7. The adjusting seat 7 can move relative to the first bag-clamping conveyor 2 or the second bag-clamping conveyor 3. The two ends of the adjusting roller 4 are respectively connected to the two adjusting seats 7. The two ends of the conveying roller 17 are respectively connected to the first bag-clamping conveyor 2 and the second bag-clamping conveyor 3.

[0052] It is understood that the adjusting seat 7 can move relative to the first bag conveying seat 2 or the second bag conveying seat 3, and the two adjusting seats 7 move synchronously with the connected adjusting roller 4.

[0053] In some embodiments, refer to the appendix Figure 2 The first bag conveying seat 2 and the second bag conveying seat 3 are both provided with sliding grooves, and the adjusting seat 7 is slidably connected to the inner wall of the sliding groove.

[0054] Specifically, the conveyor roller 17 and the adjusting roller 4 are equipped with corresponding rollers 5, which are used to contact the strip package. A rubber ring 6 is also provided at the position where the roller 5 contacts the strip package.

[0055] In some embodiments, as shown in the appendix Figure 1 and attached Figure 8 As shown in the figure, the roller 5 on the conveying roller 17 corresponds to the roller 5 on the adjusting roller 4. The contact position between the roller 5 and the strip package is set in a "concave" shape when viewed from above. During the transmission process, the strip package is located in the concave position between the two rollers 5.

[0056] The roller 5 conveys the strip package through friction, giving the strip package a stable downward driving force. By setting a rubber ring 6 on the surface of the roller 5, the friction between the roller and the strip package is increased, thereby achieving a better conveying effect for the strip package.

[0057] Specifically, it also includes a pull rod 8, the first end of which is connected to the first end of the adjusting roller 4, and the second end which passes over the conveyor roller 17 and is located outside the conveyor roller 17.

[0058] The lever 8 includes a first lever and a second lever that are connected to each other, and the first lever and the second lever are set at an angle.

[0059] The first rod passes through the first bag-clamping conveyor 2 or the second bag-clamping conveyor 3. Both first rods are located on the outer sides of both ends of the conveyor roller 17. The second rod is connected to the adjusting seat 7 on the first bag-clamping conveyor 2 or the adjusting seat 7 on the second bag-clamping conveyor 3.

[0060] In some embodiments, the pull rod 8 is L-shaped, with the first rod corresponding to the long side of the pull rod 8 and the second rod corresponding to the short side of the pull rod 8. (See attached diagram.) Figure 8 When the position of the upper middle adjusting seat 7 changes due to the thickness of the strip, the entire pull rod 8 moves through the connection of the second rod.

[0061] Specifically, the elastic adjustment of the distance between the adjusting roller 4 and the conveying roller 17 includes a limiting body 10 and an elastic element 9. The limiting body 10 is provided on the pull rod 8 and is located on the outside of the conveying roller 17.

[0062] The elastic element 9 is sleeved on the outer periphery of the pull rod 8. One end of the elastic element 9 abuts against the limiting body 10, and the other end of the elastic element 9 abuts against the frame near the conveyor roller 17. Specifically, the other end of the elastic element 9 abuts against the outer wall of the first bag clamping conveyor seat 2 or the second bag clamping conveyor seat 3.

[0063] The elastic element 9 is used to: when the strip moves to the spacing, the strip abuts against the adjusting roller 4 and moves away from the conveying roller 17. The adjusting roller 4 drives the pull rod 8 to move synchronously, so that the elastic element 9 is compressed and the spacing becomes larger.

[0064] In some embodiments, the limiting body 10 is moved to move closer to or further away from the frame, thereby adjusting the elasticity of the elastic element 9. This controls the distance between the adjusting roller 4 and the conveying roller 17, ensuring stable contact between the strip and the adjusting roller 4 and the conveying roller 17, stabilizing the friction, and thus stabilizing the conveying process of the strip.

[0065] In some embodiments, the limiting body 10 is threadedly connected to the outside of the pull rod 8, and the elastic element 9 is disposed between the limiting body 10 and the first bag conveying seat 2, or disposed between the limiting body 10 and the bracket of the second bag conveying seat 3. The length of the elastic element 9 is adjusted by rotating the limiting body 10.

[0066] Specifically, the elastic element 9 is preferably a compression spring, and this is the preferred method for adjusting the elasticity of the elastic element 9. By rotating the limiting body 10, the distance between it and the first bag-clamping conveyor seat 2 or the second bag-clamping conveyor seat 3 is adjusted by the action of the thread, thereby adjusting the elasticity of the elastic element 9.

[0067] In some embodiments, the second bag conveyor 3 is provided with a fixed seat 13, and the fixed seat 13 is provided with a power component 11 for driving the conveyor roller 17 and the adjusting roller 4 to rotate. Pulleys 12 are mounted on the shafts of both the conveyor roller 17 and the adjusting roller 4, and the power component 11 provides driving force to the two pulleys 12 through a transmission belt.

[0068] Specifically, the power component 11 is preferably an electric motor. The power component 11 can provide rotational force to the conveying roller 17 and the adjusting roller 4 through the transmission belt, and then transmit the power to the strip through the conveying roller 17 and the adjusting roller 4, so that the strip has a downward conveying force.

[0069] In some embodiments, the conveying roller 17 is connected to one of the pulleys 12 via a first coupling 14, and the adjusting roller 4 is connected to the other pulley 12 via a second coupling 15.

[0070] Specifically, the first coupling 14 is a preferred embodiment for connecting the conveyor roller 17 and the pulley 12, and the second coupling 15 is a preferred embodiment for connecting the adjusting roller 4 and the pulley 12.

[0071] In some embodiments, the pulley 12 connected to the conveyor roller 17 is located inside the transmission belt, and the pulley 12 connected to the adjusting roller 4 is located outside the transmission belt, so that the conveyor roller 17 and the adjusting roller 4 rotate in different directions.

[0072] For details, please refer to the appendix. Figure 5 The drive source of the power component 11 and the pulley 12 on the conveyor roller 17 are both located inside the transmission belt. The rotation direction of the conveyor roller 17 is the same as the rotation direction of the drive source of the power component 11, while the pulley 12 on the adjusting roller 4 is located outside the transmission belt and its rotation direction is opposite to the rotation direction of the drive source of the power component 11. This makes the rotation direction of the adjusting roller 4 opposite to that of the conveyor roller 17, so that when they rotate, they jointly drive the strip to be conveyed downward through the action of friction.

[0073] In summary, when the conveying mechanism conveys thicker strips, the limiting body 10 can be rotated to move away from the frame, reducing the elastic potential energy of the elastic element 9. This allows the adjustable gap between the conveying roller 17 and the adjusting roller 4 to increase, ensuring sufficient gap for the thicker strips to pass through while maintaining contact between the conveying roller 17 and the adjusting roller 4 and the outer surface of the strip. The friction generated by this contact makes the conveying of the strips more stable.

[0074] When the conveying mechanism transports thinner strips, the limiting body 10 can be rotated to move it closer to the frame, increasing the elastic potential energy of the elastic element 9. This reduces the adjustable gap between the conveying roller 17 and the adjusting roller 4, ensuring contact between the conveying roller 17 and the adjusting roller 4 and the outer surface of the strip when transporting thinner strips, thus guaranteeing stable transport of the thinner strips.

[0075] During the conveying of thinner or thicker strips, the distance between the conveyor roller 17 and the adjusting roller 4 can be flexibly adjusted. Furthermore, the elasticity of the elastic element 9 can protect the outer surface of the strip, preventing the outer surface of the strip from being crushed by rigid rotational transport.

[0076] After the strip is conveyed, as described above, the strip expands the distance between the conveying roller 17 and the adjusting roller 4 by contact. After the strip is conveyed, the adjusting roller 4 will move in the direction of the conveying roller 17 under the action of the elastic element 9 to complete the reset, which is convenient for subsequent use.

[0077] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

The descriptions of the embodiments above are merely for the purpose of helping to understand the solution and core idea of ​​this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
