Description

Technical Field

[0001] This invention belongs to the field of packaging equipment technology, and in particular relates to a buffer-type slide structure. Background Technology

[0002] A strip packaging machine is a machine that automatically packages products into strip-shaped bags. It features precise measurement, ease of use, and high efficiency. It is not only a new machine for packaging and sealing powdered products such as coffee, milk powder, chocolate powder, flavoring powder, medicine, sugar, and desiccants, but also a commonly used packaging equipment in the pharmaceutical industry.

[0003] The strip bag packaging machine is connected to the subsequent processing structure by a set of slides. This set of slides usually consists of two or three independent slides. The strip bag packaging machine can adjust the length of the strip bag according to different product requirements. However, after adjustment, the height of the strip bag packaging machine's discharge structure will change. The packaged strips flow directly into the subsequent process through a set of slides. Traditional slides do not have a buffering effect and are prone to damaging the strips. Therefore, a buffered slide structure is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a buffered slide structure, which uses a first spring and a second spring at the bottom of the buffer plate to buffer the falling of the strip bag, preventing damage to the finished strip bag or the raw material inside. At the same time, when the strip bag passes through the middle slide, it can be blocked by the pressure roller, thereby slowing down the strip bag and preventing it from falling quickly. It can also change the difficulty of rotating the pressure roller, thereby adjusting the deceleration effect, improving the flexibility of the structure and solving the existing technical problems.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution:

[0006] A buffer-type slide structure includes:

[0007] The discharge structure has two vertical plates fixedly connected to its bottom. The bottom of the two vertical plates is provided with a set of feeding slides consisting of an upper slide, a middle slide, and a lower slide. A buffer plate is slidably connected between the inner walls of both sides of the lower slide. A mounting base is fixedly connected to the bottom of the buffer plate, and two inclined support rods are rotatably connected within the mounting base. Two second guide rails are fixedly connected to the bottom inner wall of the lower slide. Sliding seats are slidably connected within each of the second guide rails, and the sliding seats are rotatably connected to the support rods. A first spring is fixedly connected to one side of each sliding seat, and the other end of each first spring is fixedly connected to the second guide rail. Multiple second springs are fixedly connected between the buffer plate and the lower slide. After passing through the middle slide, the strip bag can fall onto the buffer plate. The first and second springs at the bottom of the buffer plate cushion the fall of the strip bag, preventing damage to the finished strip bag or its internal raw materials.

[0008] A speed limiting mechanism is provided, which is located on one side of the central slide to limit the feeding speed of the strip bag.

[0009] Furthermore, the upper slide is fixedly connected between the two sides of the vertical plate, the middle slide is rotatably connected between the two vertical plates, and the lower slide is fixedly connected to the two sides of the first guide rail, with a slider slidably connected in each of the first guide rails. The middle slide is fixedly connected to the two sides of the connecting frame, which is rotatably connected to the slider. By installing the first guide rail and connecting frame between the middle slide and the lower slide, when the discharge structure moves up and down, the connecting frame can push the slider to slide in the first guide rail, thereby allowing the middle slide and the lower slide to rotate freely, avoiding manual adjustment and improving the automation level of the structure.

[0010] Furthermore, the speed limiting mechanism includes two mounting shafts, which are rotatably connected to both sides of the central slide and pass through the central slide. A U-shaped rubber bracket is fixedly connected between the mounting shafts, and the rubber bracket is rotatably connected between the two sides of the central slide. A pressure rod is fixedly connected to both ends of the rubber bracket, and multiple through pressure rollers are rotatably connected between the two pressure rods. When the bag passes through the central slide, it can be blocked by the pressure rollers, thereby slowing down the bag and preventing it from slipping down quickly.

[0011] Furthermore, a mounting bracket is fixedly connected to one side of the middle slide, and a through rotating sleeve is rotatably connected to one side of the mounting bracket. The rotating sleeve is coaxial with the mounting shaft. A torsion spring is fixedly connected to one side of the rotating sleeve, and the other end of the torsion spring is fixed to the mounting shaft. A pull rope is fixedly wound around the circumference of the rotating sleeve. A fixed shaft is fixedly connected to one side of the upper slide, and the other end of the pull rope is fixed to the fixed shaft.

[0012] Furthermore, one of the pressure rods is fixedly connected to one side with two guide rods, and an installation rod is slidably connected between the two guide rods. Multiple triangular rubber blocks are fixedly connected to the bottom of the installation rod, and the rubber blocks are in contact with the pressure roller. A threaded rod is threaded through the surface of the installation rod, and the other end of the threaded rod is rotatably connected to the pressure rod. After rotating the threaded rod, the position of the installation rod can be adjusted, thereby driving the wedge block to move, changing the difficulty of rotating the pressure roller, thereby adjusting the deceleration effect and improving the flexibility of the structure.

[0013] Furthermore, both sides of the lower slide are fixedly connected with a sorting bracket.

[0014] Furthermore, positioning shafts for positioning the rubber bracket are fixedly connected to the inner walls on both sides of the central slide.

[0015] The embodiments of the present invention have the following beneficial effects:

[0016] In this invention, by installing a buffer plate in the lower slide, the strip bag can fall onto the buffer plate after passing through the middle slide. The first and second springs installed at the bottom of the buffer plate cushion the fall of the strip bag, preventing damage to the finished strip bag or the raw materials inside.

[0017] In this invention, by installing rotatable pressure rollers between the two sides of the central slide, the strip bag can be blocked by the pressure rollers when passing through the central slide, thereby slowing down the strip bag and preventing it from sliding down quickly.

[0018] In this invention, by installing a first guide rail and a connecting frame between the middle slide and the lower slide, the connecting frame can push the slider to slide in the first guide rail when the discharge structure moves up and down, thereby allowing the middle slide and the lower slide to rotate freely, avoiding manual adjustment and improving the automation level of the structure.

[0019] In this invention, the installation rod and the wedge block are used in combination to adjust the position of the installation rod after rotating the threaded rod, thereby driving the wedge block to move, changing the difficulty of rotating the pressure roller, adjusting the deceleration effect, and improving the flexibility of the structure.

[0020] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0031] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0032] Example 1

[0033] Please see Figures 1-6 As shown, this embodiment provides a buffered slide structure, including: a discharge structure 1, with two vertical plates 2 fixedly connected to the bottom of the discharge structure 1. The bottom of the two vertical plates 2 is provided with a set of feeding slides consisting of an upper slide 3, a middle slide 4, and a lower slide 5. A buffer plate 11 is slidably connected between the inner walls of both sides of the lower slide 5. A buffer pad can be installed on the surface of the buffer plate 11 to increase the buffering effect. A mounting base 12 is fixedly connected to the bottom of the buffer plate 11. Two inclined support rods 13 are rotatably connected inside the mounting base 12. Two second guide rails 14 are fixedly connected to the bottom inner wall of the lower slide 5. Sliding seats 16 are slidably connected inside the two guide rails 14. The sliding seats 16 are rotatably connected to the support rods 13 respectively. A first spring 15 is fixedly connected to one side of each sliding seat 16. The other end of the first spring 15 is fixedly connected to the second guide rail 14 respectively. Multiple second springs 17 are fixedly connected between the buffer plate 11 and the lower slide rail 5. When the strip bag falls onto the buffer plate 11, the falling gravity causes the buffer plate 11 to move downward. Then, the first spring 15 and the second spring 17 buffer the buffer plate 11, thereby preventing the strip bag or the raw materials inside from breaking. Sorting brackets 6 are fixedly connected to both sides of the lower slide rail 5.

[0034] The speed limiting mechanism is located on one side of the central slide 4 to limit the feeding speed of the strip bag.

[0035] Example 2

[0036] Improvements based on Example 1: See Appendix Figures 1-6 ,include:

[0037] The discharge structure 1 has two vertical plates 2 fixedly connected to its bottom. The bottom of each vertical plate 2 is provided with a feeding chute consisting of an upper chute 3, a middle chute 4, and a lower chute 5. A buffer plate 11 is slidably connected between the inner walls of both sides of the lower chute 5. A buffer pad can be installed on the surface of the buffer plate 11 to increase the buffering effect. A mounting base 12 is fixedly connected to the bottom of the buffer plate 11. Two inclined support rods 13 are rotatably connected inside the mounting base 12. Two second guide rails 14 are fixedly connected to the inner wall of the bottom of the lower chute 5. Each second guide rail 14 is slidably connected to a sliding... The movable seat 16 and the sliding seat 16 are rotatably connected to the support rod 13 respectively. A first spring 15 is fixedly connected to one side of the sliding seat 16. The other end of the first spring 15 is fixedly connected to the second guide rail 14 respectively. Multiple second springs 17 are fixedly connected between the buffer plate 11 and the lower slide rail 5. When the strip bag falls onto the buffer plate 11, the gravity of the fall causes the buffer plate 11 to move downward. Then, the first spring 15 and the second spring 17 buffer the buffer plate 11, thereby preventing the strip bag or the raw material inside from breaking. The lower slide rail 5 is fixedly connected to both sides of the sorting bracket 6.

[0038] The speed limiting mechanism is located on one side of the central slide 4 to limit the feeding speed of the strip bag.

[0039] Reference Figure 2 The upper slide 3 is fixedly connected between the two sides of the vertical plate 2. The middle slide 4 is rotatably connected between the two vertical plates 2. The lower slide 5 is fixedly connected to the first guide rail 9 on both sides. The slider 10 is slidably connected in the first guide rail 9. The middle slide 4 is fixedly connected to the connecting frame 8 on both sides. The connecting frame 8 is rotatably connected to the slider 10 respectively. When the discharge structure 1 moves downward, the middle slide 4 and the lower slide 5 rotate, and the slider 10 slides in the first guide rail 9, thereby changing the angle of the middle slide 4 and the lower slide 5 and avoiding manual operation.

[0040] Reference Figure 4 and Figure 5 The speed limiting mechanism includes two mounting shafts 26, which are rotatably connected to both sides of the middle slide 4 and pass through the middle slide 4. A U-shaped rubber bracket 18 is fixedly connected between the mounting shafts 26. The rubber bracket 18 is rotatably connected between the two sides of the middle slide 4. A pressure rod 19 is fixedly connected to both ends of the rubber bracket 18. Multiple through pressure rollers 20 are rotatably connected between the two pressure rods 19. When the bag passes through the middle slide 4, it contacts the pressure rollers 20 and uses the pressure rollers 20 to decelerate the bag. Positioning shafts 25 for positioning the rubber bracket 18 are fixedly connected to the inner walls of both sides of the middle slide 4.

[0041] Reference Figure 5 and Figure 1A mounting bracket 27 is fixedly connected to one side of the middle slide 4. A through rotating sleeve 28 is rotatably connected to one side of the mounting bracket 27. The rotating sleeve 28 is coaxially arranged with the mounting shaft 26. A torsion spring 30 is fixedly connected to one side of the rotating sleeve 28. The other end of the torsion spring 30 is fixed to the mounting shaft 26. A pull rope 29 is fixedly wound around the circumference of the rotating sleeve 28. A fixed shaft 7 is fixedly connected to one side of the upper slide 3. The other end of the pull rope 29 is fixed to the fixed shaft 7. When the angle of the middle slide 4 becomes gentler, the descent speed of the strip bag slows down. The rotating sleeve 28 on one side of the middle slide 4 moves closer to the fixed shaft 7. The rotating sleeve 28 rotates under the action of the pull rope 29, thereby changing the torque of the torsion spring 30, reducing the torque applied to the mounting shaft 26 and the rubber bracket 18, and thus automatically changing the speed limit.

[0042] Reference Figure 4 and Figure 6 One of the pressure rods 19 has two guide rods 21 fixedly connected to one side. An installation rod 22 is slidably connected between the two guide rods 21. Multiple triangular rubber blocks 23 are fixedly connected to the bottom of the installation rod 22. The rubber blocks 23 contact the pressure roller 20 respectively. A threaded rod 24 is threadedly connected to the surface of the installation rod 22. The other end of the threaded rod 24 is rotatably connected to the pressure rod 19. Rotating the threaded rod 24 causes the installation rod 22 to rotate. The installation rod 22 causes the triangular rubber blocks 23 to move, thereby changing the contact pressure between the rubber blocks 23 and the pressure roller 20 and the difficulty of rotating the pressure roller 20, thus adjusting the speed limit.

[0043] The usage process and working principle of the technical solution of this invention are as follows:

[0044] In use, the processed strip bags enter the upper slide 3 through the discharge structure 1, then flow into the middle slide 4 through the upper slide 3, and then into the lower slide 5. They then flow to the subsequent processing through the lower slide 5. When the strip bags pass through the middle slide 4, they come into contact with the pressure roller 20. The pressure roller 20 decelerates the strip bags, while the threaded rod 24 rotates. The threaded rod 24 drives the mounting rod 22 to rotate, and the mounting rod 22 drives the triangular rubber block 23 to move, thereby changing the contact pressure between the rubber block 23 and the pressure roller 20 and the difficulty of rotating the pressure roller 20, thus adjusting the speed limit. When the strip bags fall onto the buffer plate 11, the falling gravity causes the buffer plate 11 to move downward. Then, the first spring 15 and the second spring 17 cushion the buffer plate 11, thereby preventing the strip bags or the raw materials inside from breaking.

[0045] When the discharge structure 1 moves downward, the middle slide 4 and the lower slide 5 rotate, and at the same time the slider 10 slides in the first guide rail 9, thereby changing the angle of the middle slide 4 and the lower slide 5.

[0046] When the angle of the middle slide 4 decreases, the descent speed of the strip bag decreases. The rotating sleeve 28 on one side of the middle slide 4 approaches the fixed shaft 7. The rotating sleeve 28 rotates under the action of the pull rope 29, thereby changing the torque of the torsion spring 30, reducing the torque applied to the mounting shaft 26 and the rubber bracket 18, and thus automatically changing the speed limit.
