Description

Technical Field

[0001] This utility model relates to the field of woven bag transportation, and in particular to a support device for woven bags. Background Technology

[0002] Nowadays, woven bags have a wide range of uses in various fields. They are usually made of durable polypropylene or polyethylene. Woven bags made from these materials are not only lightweight and inexpensive, but also reusable.

[0003] Chinese utility model patent (authorization announcement number: CN211810513U) discloses a woven bag sealing and feeding machine. Through the setting of a conveyor belt, a first bag-supporting wheel, a second bag-supporting wheel, a base, a motor, a rotating wheel, and a fixing mechanism, the two sets of bag-supporting wheels rotate counterclockwise, and the woven bags containing grain are transported and moved between the two sets of bag-supporting wheels. The bag-supporting wheels can support the woven bags during transportation and prevent the woven bags from tilting and tipping over on the conveyor belt.

[0004] However, in actual use, the size of woven bags often varies, and the size of the woven bags will change after being filled with grain. In this device, the first bag-supporting wheel and the second support wheel used to support the woven bags are fixed in size, so that the machine can only support a single size of woven bag. When an oversized woven bag is placed in the feeder after being filled with goods, the gap between the first and second support wheels is smaller than the size of the woven bag. When it is forced to pass through, it will cause the woven bag to be squeezed, thereby damaging the grain or spilling the grain. Utility Model Content

Detailed Implementation

[0036] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] Please see Figures 1-9 In this embodiment of the utility model, a support device for a woven bag is provided. The support device includes a conveyor belt 1 for transporting the woven bag. Rotating wheels 2 are provided on both the front and rear sides of the conveyor belt 1, and a motor 21 is provided at one end of the rotating wheel 2.

[0038] The rotating wheel 2 has a hollow structure inside, and a rotating column 22 is provided inside the hollow structure. The rotating column 22 forms an extension end that connects to the output end of the motor 21. Several shims 23 are provided around the rotating column 22 to form the wheel surface of the rotating wheel 2. A connecting plate 24 is provided at both the upper and lower end faces of the rotating column 22. Several slide rails 241 are provided on the end face of the connecting plate 24 facing the shims 23. Several sliders 231 are provided inside the slide rails 241. One end of the slider 231 is connected to the shim 23 so that the shim 23 can move in the direction of the slide rail 241.

[0039] The shim 23 and the rotating column 22 are provided with a distance adjustment device 25 for adjusting the distance between the shim 23 and the rotating column 22. The distance adjustment device 25 includes a mounting base 251 and a support base 256. One end of the mounting base 251 is detachably connected to the rotating column 22, and the other end of the mounting base 251 is movably connected to one end of the support base 256. The other end of the support base 256 abuts against one end face of the shim 23. An elastic element is provided between the mounting base 251 and the support base 256.

[0040] The working principle of this embodiment is as follows: When the worker places the woven bag filled with grain on the conveyor belt 1, the motor 21 is powered on to drive the rotating column 22 to rotate, thereby driving the entire rotating wheel 2 to rotate. The rotation direction of the rotating wheel 2 is the same as the transmission direction of the conveyor belt 1, and the rotation speed is synchronized with the transmission speed of the conveyor belt 1. When the woven bag passes through the rotating wheel 2, the rotating wheel 2 will provide support for the woven bag, so that the lower end of the woven bag is driven by the conveyor belt, and the upper end of the woven bag is supported and driven by the two rotating wheels 2.

[0041] As the size of the woven bag increases, its capacity also increases, and its volume also increases. The rotating wheel 2 is equipped with an adjustment device 25, which can adjust the distance between the pad 23 and the rotating column 22 according to the size of the woven bag. When the two rotating wheels 2 support the woven bag full of grain, the woven bag is clamped by the rotating wheels 2 at both ends. At the same time, the pad 23 on the rotating wheels 2 at both ends is also subjected to the reaction force of the woven bag. This causes the pad 23 to overcome the elastic force of the elastic element between the support seat 256 and the mounting seat 251 and slide towards the rotating column 22. This allows the rotating wheel 2 to adjust the position of the pad 23 to provide a suitable support force for the woven bag, which can prevent the grain in the woven bag from being squeezed too much, causing it to overflow or be damaged.

[0042] Further as Figure 1 As shown in this embodiment of the utility model, the rotating wheels 2 are arranged opposite to each other on the conveyor belt 1. The distance between the rotating wheels 2 at the front end of the conveyor belt 1 and the rotating wheels 2 at the rear end of the conveyor belt 1 is not greater than the bandwidth of the conveyor belt 1. When supporting the woven bags, the rotating wheels 2 at both ends of the conveyor belt 1 can change the position of the pads 23 according to the size of the woven bags to provide appropriate support force.

[0043] Further as Figure 2 and Figures 4-7 As shown in the embodiment of this utility model, the mounting base 251 includes a base 2511 and a guide post 2512. One end face of the base 2511 is detachably connected to one end of the guide post 2512. A through hole can be provided on the base 2511, which is threaded to the rotating post 22. The other end face of the base 2511 is detachably connected to the cylindrical surface of the rotating post 22. At least two sets of second slide rails 2513 are provided on the axial surface of the guide post 2512. A second slider 2514 is provided in the second slide rail 2513 to move the support base 256 toward the second slide rail 2513.

[0044] Further as Figures 4-7 As shown in the embodiment of this utility model, the support base 256 includes a sleeve 2561 and a support column 2562. The sleeve 2561 is sleeved on the guide column 2512. The support column 2562 includes a connecting end 2562a and a supporting end 2562b. The connecting end 2562a is connected to one end face of the sleeve 2561, and the supporting end 2562b abuts against one end face of the gasket 23. One end of the second slider 2514 is installed inside the sleeve 2561, and the other end of the second slider 2514 is movably installed inside the second slide rail 2513.

[0045] The working principle of this embodiment is as follows: The support seat 256 is slidably mounted on the mounting seat 251, and the gasket 23 abuts against one end of the support seat 256. When the gasket 23 is subjected to force and slides in the direction of the rotating column 22, the support seat 256 slides in the direction of the mounting seat 251 under the influence of the gasket 23. Since an elastic element is provided between the mounting seat 251 and the support seat 256, the sliding of the support seat 256 can be restricted. When the elastic force of the elastic element is greater than the pressure of the support seat 256, the elastic element will restrict the sliding of the support seat 256, thereby restricting the sliding of the gasket 23 by the support seat 256.

[0046] Further as Figures 4-7 As shown, in this embodiment of the utility model, one end of the elastic element abuts against one end face of the second slider 2514, and the other end of the elastic element abuts against one end face of the base 2511. The elastic element can be a spring 257, which is sleeved on the guide post 2512. One end of the spring 257 abuts against one end face of the second slider 2514, and the other end of the spring 257 abuts against one end face of the base 2511. The supporting force of the pad 23 on the woven bag can be changed by setting springs 257 with different elastic forces.

[0047] Further as Figures 1-3 As shown in this embodiment of the invention, one end of the connecting plate 24 is further provided with a cover 26. One end of the cover 26 is detachably connected to one end face of the connecting plate 24. The cover 26 has an edge portion 261 surrounding the connecting plate 24 to cover the opening of the slide rail 241. The connection method between the cover 26 and the connecting plate 24 includes, but is not limited to, threaded connection, plug-in connection, adhesive connection, etc.

[0048] Specifically, such as Figures 10-11 As shown, by setting a number of positioning blocks at the lower end face of the cover 26 and opening a number of positioning grooves at the upper and lower end faces of the connecting plate 24, the number and size of the positioning blocks of the cover 26 are adapted to the number and size of the positioning grooves on the connecting plate 24, so that the positioning blocks on the cover 26 can be inserted into the positioning grooves on the connecting plate 24.

[0049] like Figures 12-13As shown, another connection method between the cover 26 and the connecting plate 24 is achieved by setting threads on the cover 26 and corresponding threads on the axial surfaces of the connecting plate 24 at both ends that connect to the cover 26, so that the cover 26 can be installed on the connecting plate 24 by threaded connection.

[0050] Further as Figure 14 As shown in the embodiment of this utility model, the support device also includes a collection bin 3, which is located at one end of the conveyor belt 1. A filter screen 31 is provided at the upper end of the collection bin 3, and a drawer 32 is also provided inside the collection bin 3. The opening of the drawer 32 is connected to the filter screen 31 to form a filtration space.

[0051] The working principle of this embodiment is as follows: The collection bin 3 is placed at the end of the conveyor belt 1 to collect the grain that falls on the conveyor belt 1. At the same time, it also allows the woven bags to fall onto the filter screen 31 on the collection bin 3. The fallen grain falls into the drawer 32 through the filter screen 31, thereby completing the collection of scattered grain and reducing grain waste.

[0052] It will be apparent to those skilled in the art that this invention 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 essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
