Description

Technical Field

[0001] This utility model relates to the field of product packaging technology, specifically to an automatic material shaking device for packaging. Background Technology

[0002] An automatic material-shaking device for packaging is a piece of equipment used in the packaging process to promote the even distribution of materials within a bag or container. This device solves problems such as material accumulation, blockage, or uneven distribution that may occur during filling or packaging through automation, thereby improving packaging efficiency and product quality.

[0003] A search revealed that patent CN202323255595.9 discloses an automatic material-shaking device for packaging. While this device uses a vibrating motor to drive a vibrating plate, and then further compacts the PET bottle flakes filled into the packaging bag via a crossbar and pressure ring, reducing gaps between the PET bottle flakes without moving the packaging bag and preventing damage, the device's vibration motor is directly mounted on the U-shaped plate. This causes the entire device to vibrate during use, leading to decreased stability. Prolonged vibration may cause internal components to loosen or break, affecting the device's normal operation and lifespan. Furthermore, the direct mounting of the vibration motor on the U-shaped plate generates significant noise. This can damage the operator's hearing and cause noise pollution, disrupting other work and daily life. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic material shaking device for packaging, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] An automatic shaking device for packaging includes a base plate, a power module mounted on the base plate, and a vibratory feeder mounted on one end of the base plate opposite to the power module.

[0007] The vibratory feeder is provided with a first support plate and a second support plate. A surrounding plate is provided above the second support plate. A vibration module is provided at the bottom end of the first support plate. Support springs are provided on both sides of the bottom surface of the first support plate located on the vibration module. The first support plate is supported and mounted on the base plate by the support springs. An air spring is installed on the lower surface of the second support plate. The second support plate is supported and mounted on the base plate by the air springs.

[0008] The vibration module is equipped with a bearing housing, in which an eccentric rotor is rotatably mounted. The power module is equipped with a gearbox, on which a drive shaft is mounted. The gearbox is connected to the eccentric rotor via the drive shaft.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the vibration module is located on the center line of the first support plate, and the vibration module is driven to vibrate by the eccentric rotation of the eccentric rotor.

[0011] The beneficial effects of adopting the above-mentioned further solutions are:

[0012] The vibration module is located on the center line of the first pallet, meaning the energy generated by vibration can be evenly distributed in all directions. This design ensures that the vibration effect is uniform across the entire first pallet, thus avoiding problems such as uneven material distribution or inconsistent compaction caused by uneven vibration. The eccentric rotor generates vibration through eccentric rotation, a vibration method characterized by concentrated energy and excellent vibration effect. Because the eccentric rotor is located at the center of the vibration module, it ensures that the vibration energy is evenly distributed across the entire vibration module. Placing the vibration module on the center line of the first pallet helps maintain the balance of the entire device. During vibration, because the vibration energy generated by the vibration module is evenly distributed, it will not generate excessive impact force or torque on other parts of the device, thus ensuring the structural stability of the device.

[0013] Furthermore, an upper sleeve is installed at the bottom end of the second support plate on one side of the air spring, and a plug rod is installed on the base plate. The second support plate is installed on the base plate by interlocking and limiting the upper sleeve and the plug rod.

[0014] The beneficial effects of adopting the above-mentioned further solutions are:

[0015] The second pallet is stably mounted on the base plate through the interlocking of the upper sleeve and the connecting rod. This interlocking and limiting design not only ensures the fixed position of the second pallet on the base plate but also prevents it from shifting during vibration, thus guaranteeing the stability of the entire device. An air spring is located between the second pallet and the base plate, providing excellent elastic support. This support method not only helps absorb and disperse vibration energy but also allows for adjustment of the support force as needed, ensuring the stability of the second pallet and the material on it during vibration.

[0016] Furthermore, the plug rod is provided with a limiting pin, and the upper sleeve is provided with a guide groove. The upper sleeve and the plug rod limit the movement distance through the limiting pin and the guide groove, thereby limiting the movement distance of the second pallet.

[0017] The beneficial effects of adopting the above-mentioned further solutions are:

[0018] By sliding the limiting pin within the guide groove, the movement distance of the upper sleeve relative to the insertion rod can be precisely controlled. This design ensures that the displacement of the second pallet during vibration is strictly limited within a predetermined range, thereby improving the stability and reliability of the device. When the vibration module is working, the second pallet will be affected by vibration and experience some displacement. However, due to the limiting effect of the limiting pin and guide groove, the displacement of the second pallet is controlled within a reasonable range, avoiding problems such as material spillage or device damage caused by excessive vibration.

[0019] Furthermore, the second tray is symmetrically distributed on both sides of the first tray.

[0020] The beneficial effects of adopting the above-mentioned further solutions are:

[0021] The second support plates are symmetrically distributed on both sides of the first support plate. This design makes the entire device more structurally balanced. During vibration, because the second support plates on both sides are affected by the same vibration, they can cancel out some of the vibration energy, thereby improving the stability of the device. The symmetrically distributed second support plates help reduce the interference of vibration on other parts of the device. When the vibration module is working, the vibration energy is evenly transmitted to the second support plates on both sides, avoiding the problem of device tilting or swaying caused by unilateral vibration.

[0022] This utility model provides an automatic material shaking device for packaging. It has the following beneficial effects:

[0023] The device supports the first and second support plates using both support springs and air springs. This dual-support structure makes the device more stable during vibration and reduces swaying caused by vibration. Both the support springs and air springs have good shock absorption effects, effectively absorbing and dispersing vibration energy, thereby reducing the impact of vibration on the device itself and the surrounding environment.

[0024] The air spring can adjust its internal air pressure as needed, thereby enabling flexible adjustment of the height and stiffness of the second pallet. This adjustment method allows the device to adapt to different materials and packaging requirements. Through the cooperation of the limit pin and guide groove, the movement distance of the second pallet can be precisely limited, thereby ensuring that the vibration module does not produce excessive displacement during operation, guaranteeing the stability and reliability of the device.

[0025] The power module is connected to the eccentric rotor via a gearbox and drive shaft. This transmission method offers advantages such as simple structure, high transmission efficiency, and convenient maintenance. Since key components like the gearbox and drive shaft are located on the base plate and have a relatively simple structure, maintenance and upkeep are easier. The vibration module generates vibration through the eccentric rotation of the eccentric rotor. This vibration method features concentrated energy and excellent vibration effect. Because this device can be adapted to different materials and packaging requirements by adjusting components such as air springs and limit pins, its application range is very wide.

[0033] 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.

[0034] Please see Figures 1 to 3 As shown, the embodiments provided by this utility model are as follows:

[0035] Example 1

[0036] An automatic shaking device for packaging includes a base plate 3, on which a power module 2 is mounted. A vibratory feeder 1 is mounted on one end of the base plate 3 opposite to the power module 2. The vibratory feeder 1 has a first support plate 107 and a second support plate 108, which are symmetrically distributed on both sides of the first support plate 107. This symmetrical distribution of the second support plates 108 on both sides of the first support plate 107 makes the entire device more structurally balanced. During vibration, since the second support plates 108 on both sides are affected by the same vibration, they can cancel out some of the vibration energy, thereby improving the stability of the device. The symmetrical distribution of the second support plates 108 on both sides of the first support plate 107 inherently provides balance. In physics, symmetrical structures tend to better resist external disturbances and maintain system stability. When the vibration module 106 operates, the generated vibration energy is evenly transmitted to the second support plates 108 on both sides. Since the second support plates 108 on both sides have the same structure and are symmetrically distributed, they can respond to vibration in a "mirror image" manner, thereby canceling out vibration energy to a certain extent. The symmetrically distributed second support plates 108 help reduce vibration interference to other parts of the device. When the vibration module 106 is working, the vibration energy is evenly transmitted to the second support plates 108 on both sides, avoiding the problem of device tilting or shaking caused by unilateral vibration. A surrounding plate 109 is provided above the second support plates 108, and the vibration module 106 is provided at the bottom end of the first support plate 107. Support springs 110 are provided on both sides of the bottom surface of the first support plate 107 located on the vibration module 106. The first support plate 107 is supported and mounted on the base plate 3 by the support springs 110. The second support plates 108... An air spring 101 is installed on the lower surface of the device. The second support plate 108 is supported and mounted on the base plate 3 by the air spring 101. An upper sleeve 102 is installed at the bottom end of the second support plate 108, located on one side of the air spring 101. A plug-in rod 103 is installed on the base plate 3. The second support plate 108 is mounted on the base plate 3 by interlocking the upper sleeve 102 and the plug-in rod 103. Through the interlocking of the upper sleeve 102 and the plug-in rod 103, the second support plate 108 is stably mounted on the base plate 3. This interlocking and limiting design not only ensures that the second support plate 108 is fixed in position on the base plate 3, but also prevents the second support plate 108 from shifting during vibration, thereby ensuring the stability of the entire device. The air spring 101 is located between the second support plate 108 and the base plate 3, providing good elastic support.This support method not only helps absorb and disperse vibration energy, but also allows for adjustment of the support force according to actual needs, ensuring that the second pallet 108 and the material on it remain stable during vibration. The plug-in rod 103 is equipped with a limiting pin 104, and the upper sleeve 102 has a guide groove 105. The upper sleeve 102 and the plug-in rod 103 limit their movement distance through the limiting pin 104 and the guide groove 105, thereby limiting the movement distance of the second pallet 108. By sliding the limiting pin 104 within the guide groove 105, the movement distance of the upper sleeve 102 relative to the plug-in rod 103 can be precisely controlled. This design ensures that the displacement of the second pallet 108 during vibration is strictly limited within a predetermined range, thus improving the stability and reliability of the device. When the vibration module 106 is working, the second pallet 108 will be affected by vibration and experience a certain displacement. However, due to the limiting effect of the limiting pin 104 and the guide groove 105, the displacement of the second pallet 108 is controlled within a reasonable range, avoiding problems such as material spillage or device damage caused by excessive vibration.

[0037] Example 2

[0038] To ensure the vibration effect, for example, such as Figures 1 to 3 As shown, the present invention further includes: a vibration module 106 with a bearing seat 1061, an eccentric rotor 1062 rotatably mounted within the bearing seat 1061, the vibration module 106 being located on the center line of the first pallet 107, and the vibration module 106 vibrating via the eccentric rotation of the eccentric rotor 1062. The vibration module 106 being located on the center line of the first pallet 107 means that the energy generated by the vibration can be evenly diffused in all directions. This design ensures that the vibration effect is uniform across the entire first pallet 107, thereby avoiding problems such as uneven material distribution or inconsistent compaction effects caused by uneven vibration. The eccentric rotor 1062 generates vibration through eccentric rotation, a vibration method characterized by concentrated energy and good vibration effect. Since the eccentric rotor 1062 is located at the center of the vibration module 106, it ensures that the vibration energy is evenly distributed across the entire vibration module 106. Placing the vibration module 106 on the center line of the first pallet 107 helps maintain the balance of the entire device. During the vibration process, since the vibration energy generated by the vibration module 106 is uniformly distributed, it will not generate excessive impact force or torque on other parts of the device, thereby ensuring the structural stability of the device. The power module 2 is equipped with a gearbox 202, on which a drive shaft 201 is installed. The gearbox 202 is connected to the eccentric rotor 1062 through the drive shaft 201.

[0039] Working principle:

[0040] When the device needs to operate, power module 2 starts. Gearbox 202 in power module 2 transmits power to eccentric rotor 1062 in vibration module 106 via drive shaft 201. Eccentric rotor 1062 begins to rotate eccentrically under the drive of gearbox 202. This eccentric rotation generates vibration on the first support plate 107. The first support plate 107 is connected to the base plate 3 via support spring 110. The vibration generated by vibration module 106 is transmitted to the first support plate 107 and then...

[0041] The material is transferred from the first pallet 107 to the vibratory plate 1.

[0042] When the vibration module 106 vibrates, the material on the vibrating plate 1 is affected by the vibration and begins to shake. This shaking helps the material to be evenly distributed on the vibrating plate 1 and reduces the gaps between the materials. In addition to shaking, the vibration of the vibration module 106 also has a certain compaction effect on the material. This compaction effect helps the material to be arranged more tightly in the packaging bag or container, thereby improving the accuracy and aesthetics of the packaging.

[0043] The second pallet 108 is connected to the base plate 3 via an air spring 101. The air spring 101 has good elasticity and shock absorption, effectively absorbing and dispersing vibration energy, thereby reducing impact and damage to the base plate 3. A support spring 110 is located at the bottom end of the first pallet 107. The height and stiffness of the first pallet 107 can be flexibly adjusted through the adjustment of the support spring 110. This adjustment helps adapt to different materials and packaging requirements, ensuring the stability and reliability of the device.

[0044] The limiting pin 104 is inserted into the guide groove 105. Through the cooperation of the limiting pin 104 and the guide groove 105, the movement distance of the second support plate 108 can be precisely limited. When the vibration module 106 vibrates, the second support plate 108 will be affected by the vibration and produce a certain displacement. However, due to the limiting effect of the limiting pin 104 and the guide groove 105, the displacement of the second support plate 108 will be controlled within a certain range, thereby ensuring the stability and reliability of the device.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
