Description

Technical Field

[0001] This utility model relates to the field of packaging and feeding technology, and in particular to a loading device and packaging equipment for a stretch film packaging machine. Background Technology

[0002] When using a stretch film baler to pack materials, overhead cranes are typically used for loading. However, overhead crane resources are limited, and subsequent packing processes require a significant wait time when the crane is transferring other materials, resulting in low packing efficiency. Related technologies include using forklifts to replace overhead cranes for transferring materials to the loading device. Compared to overhead cranes, forklifts have more resources, are more flexible in scheduling, and have higher transportation efficiency. However, the forklift's fork arm length is limited, preventing it from loading goods directly to the packing position. Therefore, how to use forklifts to transport materials and load them to the packing position remains a technical problem to be solved. Utility Model Content

[0051] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0052] The following is for reference. Figures 1-24 This invention describes a loading device 100 for a stretch film packaging machine according to an embodiment of the present invention.

[0053] Reference Figures 1-4 According to the first aspect of the present invention, a loading device 100 for a stretch film packaging machine includes a base 1, a bracket 2 and a locking mechanism 3. The base 1 is rotatable in the horizontal direction. The bracket 2 is disposed on the base 1 and can move relative to the base 1 between the loading position and the packaging position. The bracket 2 is used to support and place materials. The locking mechanism 3 is disposed on the base 1. When the bracket 2 is in the packaging position, the locking mechanism 3 is used to lock and fix the bracket 2.

[0054] The base 1 can support and fix the bracket 2 and the locking mechanism 3. The base 1 can rotate in the horizontal direction, which can facilitate the wrapping of materials and the connection with loading equipment from different directions, making loading more flexible, such as forklifts. By rotating the base 1, the angle of the bracket 2 can be adjusted so that the bracket 2 can be connected to forklifts from different directions, making loading more flexible.

[0055] The bracket 2 can move relative to the base 1 between the loading position and the packaging position. The bracket 2 is used to support the placement of materials. The bracket 2 can support and transfer materials. For example, when the bracket 2 is in the loading position, materials can be placed on the bracket 2 by a forklift. By moving the bracket 2 from the loading position to the packaging position, the process of moving materials from the loading position to the packaging position can be completed. This makes the material movement process simpler and more convenient, which is conducive to improving the subsequent packaging efficiency.

[0056] When the tray 2 is in the packaging position, the locking mechanism 3 is provided to lock and fix the tray 2, which can fix the tray 2 and the material in the packaging position more stably. This can prevent the tray 2 or the material from shifting relative to the base 1 during the wrapping process, and can also reduce the possibility of the material's center of gravity shifting and thus reducing the packaging quality, or even the possibility of the material slipping.

[0057] The base 1 can rotate horizontally, and the bracket 2 can move between the loading position and the packaging position relative to the base 1, making the overall structure of the loading device 100 compact. This reduces the requirements for working space and eliminates the need for a specific orientation or layout. The angle of the bracket 2 can be adjusted by rotating the base 1, so that the loading and packaging of materials can be completed in various spaces, which helps to reduce the cost related to working space.

[0058] According to the present invention, the loading device 100 for a stretch film packaging machine has a bracket 2 on the base 1 that can move relative to the base 1 between the loading position and the packaging position. The bracket 2 is used to support and place materials. By moving the position of the bracket 2, the materials can be moved from the loading position to the packaging position. This makes the material movement process simpler and more convenient, which is beneficial to improving packaging efficiency. Furthermore, when the bracket 2 is in the packaging position, a locking mechanism 3 is provided to lock and fix the bracket 2, which can fix the bracket 2 more stably in the packaging position. This makes the materials more stably located in the packaging position for packaging, thereby reducing or avoiding the possibility that the bracket 2 or the materials will shift relative to the base 1 due to the rotation of the base 1 during the packaging process.

[0059] Reference Figure 1 , Figure 2 , Figure 11 and Figure 12 According to some embodiments of this utility model, the feeding position and the packaging position are arranged at intervals along a first direction (e.g., referring to direction e1 in the attached drawings). The base 1 is provided with a guide rail 11 extending along the first direction. The bracket 2 is supported by the guide rail 11 and is movable along the extending direction of the guide rail 11. The guide rail 11 can support the bracket 2 and guide and limit the movement of the bracket 2, allowing the bracket 2 to move along a set trajectory and in a set direction, reducing or avoiding the possibility of the bracket 2 disengaging from the guide rail 11 during movement. For example, the movement trajectory of the bracket 2 can be restricted to allow the bracket 2 to move between the feeding position and the packaging position, reducing the time wasted on repeated positioning.

[0060] Reference Figure 1 , Figure 2 , Figure 10 and Figure 11In some embodiments, the guide rail 11 includes a guide rail body 113 and a reinforcing plate 112. The bracket 2 is supported on the guide rail body 113. The reinforcing plate 112 is disposed on the side of the guide rail body 113 away from the bracket 2 and is fixed to the base 1. The projected area of ​​the reinforcing plate 112 on the reference plane is not less than the projected area of ​​the guide rail body 113 on the reference plane. The reference plane intersects with the first direction. The reinforcing plate 112 can enhance the overall structural strength of the guide rail 11 to a certain extent. Since the projected area of ​​the reinforcing plate 112 on the reference plane is not less than the projected area of ​​the guide rail body 113 on the reference plane, the reinforcing plate 112 can increase the contact area between the guide rail body 113 and the base 1, thereby enhancing the connection strength between the guide rail body 113 and the base 1.

[0061] Reference Figure 1 , Figure 3 , Figure 4 , Figure 14 and Figure 15 According to some embodiments of this utility model, the bottom of the bracket 2 is provided with a roller 21, which is supported on the guide rail 11 and makes rolling contact with the guide rail 11. The guide rail 11 can support the ball bearings. When the bracket 2 moves relative to the guide rail 11, the roller 21 makes rolling contact with the guide rail 11, which can reduce the friction when the bracket 2 moves relative to the guide rail 11 and increase the smoothness of the relative movement, thereby making the bracket 2 move more smoothly between the packaging position and the loading position.

[0062] Reference Figure 1 , Figure 4 , Figure 5 and Figure 25 According to some embodiments of the present invention, the locking mechanism 3 includes a locking pin 31, the bracket 2 has a first limiting hole 221, the guide rail 11 is provided with a limiting block 111, and the limiting block 111 has a second limiting hole 1114. When the bracket 2 is in the packaging position, the locking pin 31 passes through the first limiting hole 221 and the second limiting hole 1114 to lock and fix the bracket 2 in the packaging position.

[0063] By inserting the locking pin 31 through the first limiting hole 221 and the second limiting hole 1114, a locking and fixing mechanism can be formed between the bracket 2, the locking pin 31 and the limiting block 111. This can limit the displacement or shaking of the bracket 2. For example, it can prevent the bracket 2 from moving relative to the guide rail 11 in the first direction, so that the bracket 2 is more stably fixed in the packaging position, so that the material is more stably fixed in the packaging position, and avoids the possibility of the winding trajectory deviating due to the displacement of the bracket 2.

[0064] In some embodiments, the limiting block 111 includes a first limiting block 111 body and a second limiting block 111 body, which are arranged at intervals along a first direction. The first limiting block 111 body forms a second limiting insertion hole 1114, and the second limiting block 111 body forms a third limiting insertion hole. When the bracket 2 is in the packaging position, the locking pin 31 passes through the first limiting insertion hole 221 and the second limiting insertion hole 1114 to lock and fix the bracket 2 to the packaging position. The packaging position allows the material to be positioned more stably for the packaging process, reducing the possibility of the material's center of gravity shifting due to the displacement of the bracket 2 when the base 1 rotates. When the bracket 2 is in the loading position, the locking pin 31 passes through the first limit hole 221 and the third limit hole to lock and fix the bracket 2 in the loading position. This allows the bracket 2 to be positioned more stably in the loading position, avoiding the possibility of the bracket 2 moving relative to the guide rail 11 due to the impact force when the material is placed.

[0065] Reference Figure 5 , Figure 6 , Figure 22 and Figure 23 According to some embodiments of the present invention, the bracket 2 has a connecting flange 22 formed along the edge of the first direction, the connecting flange 22 has a first limiting insertion hole 221, the limiting block 111 includes a support plate 1111, a connecting plate 1112 and a limiting plate 1113, the support plate 1111 and the limiting plate 1113 are arranged at intervals in the vertical direction and together define an avoidance space 1115, the support plate 1111 is fixed to the base 1, the connecting plate 1112 extends in the vertical direction and is used to connect the support plate 1111 and the limiting plate 1113, the limiting plate 1113 has a second limiting insertion hole 1114, when the bracket 2 is in the packaging position, at least a portion of the connecting flange 22 is located below the limiting plate 1113 and is accommodated in the avoidance space 1115.

[0066] Wherein, at least a portion of the connecting flange 22 is located below the limiting plate 1113 and is accommodated in the clearance space 1115, it may include the following situations: for example, a portion of the connecting flange 22 may be located below the limiting plate 1113 and accommodated in the clearance space 1115; or, for another example, the entire connecting flange 22 may be located below the limiting plate 1113 and accommodated in the clearance space 1115.

[0067] The connecting flange 22 can enhance the overall structural strength of the bracket 2 to a certain extent. By positioning the connecting flange 22 at the edge of the bracket 2 along the first direction, the space occupied by the connecting flange 22 for material placement can be reduced, thus avoiding a reduction in the effective support area of ​​the bracket 2 for materials due to the presence of the connecting flange 22.

[0068] When the bracket 2 is in the packaging position, at least a portion of the connecting flange 22 is located below the limiting plate 1113 and accommodated in the clearance space 1115. The clearance space 1115 can be fully utilized, so that the limiting plate 1113 can limit at least a portion of the connecting flange 22 in the vertical direction, reducing or avoiding the possibility of the connecting flange 22 moving relative to the limiting block 111 in the vertical direction, and further enhancing the stability of the bracket 2 when it is fixed in the packaging position.

[0069] Reference Figures 1-4 According to some embodiments of this utility model, the limiting mechanism 4 includes a first limiting seat 41 and a second limiting seat 42. The first limiting seat 41 and the second limiting seat 42 are arranged at intervals along a first direction and are located on opposite sides of the bracket 2 along the first direction. When the bracket 2 is in the packaging position, the first limiting seat 41 abuts against the bracket 2 in the first direction. When the bracket 2 is in the feeding position, the second limiting seat 42 abuts against the bracket 2 in the first direction. By limiting the bracket 2 with the first limiting seat 41 and the second limiting seat 42 respectively, the bracket 2 can be positioned. The first limiting seat 41 abuts against the bracket 2 to determine that the bracket 2 is in the packaging position, or the second limiting seat 42 abuts against the bracket 2 to determine that the bracket 2 is in the feeding position. This saves the time wasted by repeatedly positioning the bracket 2 and helps to improve the overall production efficiency.

[0070] Reference Figures 16-20 According to some embodiments of the present invention, the first limiting seat 41 includes a first seat body 411 and a first buffer pad 412, the first buffer pad 412 being disposed on the first seat body 411 and facing the bracket 2. By disposing of the first buffer pad 412 on the first seat body 411 and facing the bracket 2, the first buffer pad 412 can buffer the impact force between the bracket 2 and the first seat body 411, reducing frictional wear caused by collision between the bracket 2 and the first seat body 411.

[0071] Reference Figure 1 and Figure 2 According to some embodiments of the present invention, the second limiting seat 42 includes a second seat body and a second buffer pad, the second buffer pad being disposed on the second seat body facing the bracket 2. By disposing of the second buffer pad on the second seat body facing the bracket 2, the second buffer pad can buffer the impact force between the bracket 2 and the second seat body, reducing the friction and wear caused by the collision between the bracket 2 and the second seat body.

[0072] Reference Figures 16-20According to some embodiments of the present invention, the first limiting seat 41 includes a first seat body 411, the first seat body 411 includes a first support part 413 and a first limiting part 414, the first support part 413 and the first limiting part 414 are arranged at an angle, the first support part 413 is fixed to the base 1, the first limiting part 414 extends in the vertical direction, one end of the first limiting part 414 is fixed to the first support part 413, and the other end of the first limiting part 414 is connected to the first support part 413 by a first reinforcing part 415, the first reinforcing part 415 extends obliquely in the vertical direction.

[0073] The first support portion 413 is fixed to the base 1, providing stable support for the entire first limiting seat 41. The first limiting portion 414 extends vertically, increasing the contact area between the first limiting seat 41 and the bracket 2, thus enhancing the limiting effect of the first limiting seat 41 on the bracket 2. The first reinforcing portion 415 can enhance the overall structural strength of the first limiting seat 41 to a certain extent. The first reinforcing portion 415 connects the first support portion 413 and the first limiting portion 414, forming a triangular structure. For example, the geometric stability of the triangle can be used to disperse the impact force on the first limiting portion 414, reducing the possibility of deformation due to impact.

[0074] According to some embodiments of the present invention, the second limiting seat 42 includes a second seat body, the second seat body includes a second support part and a second limiting part, the second support part and the second limiting part are arranged at an angle, the second support part is fixed to the base 1, the second limiting part extends in the vertical direction, one end of the second limiting part is fixed to the second support part, and the other end of the second limiting part is connected to the second support part by a second reinforcing part, the second reinforcing part extends obliquely in the vertical direction.

[0075] The second support portion is fixed to the base 1, providing stable support for the entire second limiting seat 42. By extending vertically, the second limiting portion increases the contact area between the second limiting seat 42 and the bracket 2, thereby enhancing the limiting effect of the second limiting seat 42 on the bracket 2. The second reinforcing portion can, to a certain extent, enhance the overall structural strength of the second limiting seat 42. The second reinforcing portion connects the second support portion and the second limiting portion, forming a triangular structure. For example, the geometric stability of the triangle can be used to disperse the impact force on the second limiting portion, reducing the possibility of deformation due to impact.

[0076] Reference Figure 1 and Figure 2According to some embodiments of the present invention, there are two guide rails 11, which are arranged at intervals along a second direction (for example, refer to the e2 direction in the figure). In the second direction, the distance between the two guide rails 11 and the geometric center of the base 1 is the same. The second direction intersects the first direction. The size of the bracket 2 in the second direction is not less than the distance between the two guide rails 11, and the distance between the two ends of the bracket 2 along the second direction and the guide rail 11 on the adjacent side is the same.

[0077] The two guide rails 11 are symmetrically distributed along the second direction to form a symmetrical support structure. The distance between the two ends of the bracket 2 and the adjacent guide rail 11 along the second direction is the same. This allows the center of gravity of the bracket 2 or the material to be located between the two guide rails 11 along the second direction, so that the weight of the bracket 2 or the material is evenly transferred to the two guide rails 11 along the second direction. This avoids the possibility of deformation or damage to the guide rail 11 due to overload on one side, and also reduces the possibility of the base 1 tilting due to excessive force on the guide rail 11 on one side.
