Description

Technical Field

[0001] This utility model relates to the field of raw material transfer technology, specifically to a fork guide mechanism for a film raw material transfer forklift. Background Technology

[0002] In the transfer of film raw materials, forklifts are generally used for short-distance transport. Common small-volume goods are stacked on wooden pallets, and are moved and transported by inserting the forks of the forklift into the wooden pallets and lifting them to a certain height.

[0003] During the transfer of film raw materials, because the film raw materials contain large-volume rolls, the rolls are not temporarily stored on wooden pallets but placed directly on the ground. The forks are then slid along the ground towards the roll until they penetrate the bottom of the roll, and then lifted upwards and moved to the designated position to complete the transfer. However, during this insertion process, the forks, due to their thickness, often cause the top of the forks to be higher than the ground. This often results in pressure damage to the outer layer of the roll, requiring manual trimming before it can be used.

[0004] Even if the top surface of the forks is designed with an inclined stepped shape in the existing technology, this inclined stepped design state can be achieved by... Figure 1 Let's illustrate this with an example. In the diagram, 'a' represents the fork. The inclined step design creates an inclined step at the top of the fork insertion point, minimizing the height difference between the inclined step and the ground. Despite this inclined step design, the inclined step still has a certain height from the ground, which may still cause excessive compression on the outside of the coil. If the fork is further modified to have a sloped transition between the top of the step and the ground, this modification requires changing the original fork structure. This not only incurs higher modification costs but also reduces the scenarios the fork can be used in. For example, when using this modified fork to insert a wooden pallet, the sharp end formed by the inclined surface of the fork may damage the wooden pallet, making this transfer scenario unsuitable.

[0005] Based on this, we propose a fork guiding mechanism for a film raw material transfer forklift to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to solve the problems in the prior art by proposing a fork guide mechanism for a film raw material transfer forklift. This guide mechanism eliminates the gap between the forks and the ground by setting a flat transition part, so that the raw materials will not be squeezed or damaged during the process of the forks moving towards the raw materials.

[0007] To solve the above problems, this utility model provides the following technical solution:

[0008] A fork guiding mechanism for a film raw material transfer forklift includes a guide assembly sleeved on the fork. The guide assembly includes a horizontal part and a flat transition part connected to the horizontal part. The horizontal part has a chamber that can be sleeved on the fork and a locking member. The locking member is used to lock the horizontal part on the fork. The flat transition part has a transition slope, one end of which is flush with the horizontal part and the other end is flush with the ground to eliminate the gap between the fork and the ground.

[0009] As a further embodiment of this utility model, the locking element is disposed on the side of the horizontal part to avoid interfering with the working path of the top of the guide assembly.

[0010] As a further embodiment of this utility model: the locking member includes a fastening bolt disposed on the side of the horizontal part, and one end of the fastening bolt extends into the cavity. Multiple fastening bolts are provided and evenly distributed on both sides of the horizontal part. The multiple fastening bolts are located between one end of the cavity to form an adjustable clamping area, which is used to clamp the forks.

[0011] As a further embodiment of this utility model: the locking component includes a shaft rotatably mounted on the horizontal part, with one end of the shaft extending into the cavity. A bidirectional threaded rod is rotatably mounted in the cavity, and the bidirectional threaded rod is connected to the shaft in a driving connection. The bidirectional threaded rod has two threaded segments with opposite threads. Two sets of clamping blocks are slidably mounted in the cavity, with the two clamping blocks threadedly sleeved on the two threaded segments respectively. The two clamping blocks form an adjustable clamping area. The shaft, the bidirectional threaded rod, and the two clamping blocks together form a clamping structure, which is configured as two sets and evenly distributed on both sides of the horizontal part.

[0012] As a further embodiment of this utility model: the bottom surface of the clamping block is inclined to match the slope of the top surface of the fork, so that the bottom surface of the clamping block and the top surface of the fork are in surface contact.

[0013] As a further embodiment of this utility model: a first bevel gear is provided at one end of the shaft located in the cavity, and a second bevel gear is provided on the bidirectional threaded rod, and the second bevel gear meshes with the first bevel gear for transmission.

[0014] As a further embodiment of this utility model: the guide mechanism also includes a locking device for locking the position of the shaft. The locking device includes a cylinder fixedly mounted on the horizontal part, and the cylinder is arranged radially along the shaft. A pin that slides along its length is movably inserted inside the cylinder, and a slot for inserting the pin is provided on the outside of the shaft.

[0015] As a further embodiment of this utility model: the guiding mechanism includes a limiting component, which includes a bracket respectively disposed on the inner wall of the top and the inner wall of the bottom of the chamber, and a limiting roller is rotatably disposed on the bracket, forming a sleeved engagement area between the two limiting rollers.

[0016] As a further embodiment of this utility model: multiple assist rollers are provided on the transition slope surface in a rotatable manner along its slope direction.

[0017] As a further embodiment of this utility model: the inner wall of the cavity is provided with a sliding groove for the movable installation of the clamping block.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. This guiding mechanism achieves a smooth transition between the forks and the ground through the integrated design of the horizontal section and the flat transition section. The transition ramp, with one end flush with the horizontal section and the other end flush with the ground, completely eliminates the height difference between the forks and the ground, avoiding bumps or jamming damage caused by discontinuity when handling film materials. Meanwhile, the detachable guiding assembly is fixed to the forks by locking devices, ensuring installation stability and facilitating maintenance and replacement.

[0020] 2. The locking mechanism is located on the side of the horizontal section, avoiding the occupation of the operating space above the forks by traditional top locking methods. This side-mounted design optimizes the top working path of the guide assembly, ensuring that the forks are not interfered with by the locking mechanism when inserting or withdrawing goods, thus improving operational smoothness and safety.

[0021] 3. An adjustable clamping zone is formed by multiple sets of evenly distributed fastening bolts. The clamping force is adjusted synchronously by the symmetrically distributed bolts to achieve uniform clamping of the forks. This design not only enhances compatibility with different fork sizes, but also prevents local stress concentration by applying pressure at multiple points, avoiding deformation or wear on the fork surface.

[0022] 4. The structure, driven by a shaft and a bidirectional threaded rod, allows two sets of clamping blocks to move synchronously in opposite directions, creating symmetrical clamping force. This design significantly improves clamping stability and, by utilizing the self-locking characteristic of the threaded drive, ensures no risk of loosening during clamping. Furthermore, the insertion lock allows for position locking of the shaft, further guaranteeing the stable maintenance of the clamping area.

[0023] 5. The bottom surface of the clamping block is inclined to match the slope of the top surface of the fork, so that the clamping surface and the surface of the fork are in full contact. This surface contact design not only ensures the stability of the clamping action, but also plays a certain role in preventing slippage.

[0024] 6. The locking mechanism uses a pin to mechanically lock the shaft in a slot, achieving circumferential fixation. This structure completely eliminates the risk of accidental rotation of the shaft, ensuring long-term stability of the clamping state. Simultaneously, the radial arrangement of the cylinder simplifies the pin's operating path, improving locking / unlocking efficiency.

[0025] 7. The limiting assembly, formed by upper and lower limiting rollers, fits into the positioning area to provide precise guidance for fork insertion. The rolling characteristics of the limiting rollers reduce the frictional resistance between the forks and the guide assembly, preventing scratches on the fork surface. At the same time, physical limiting prevents fork deviation, improving operational safety.

[0026] 8. An assist roller is installed on the transition slope to replace sliding friction with rolling friction, significantly reducing resistance when moving goods. This design reduces the manual labor intensity of pushing and pulling goods and avoids surface damage to the film material caused by friction. Attached Figure Description

[0036] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0037] like Figure 2 As shown, a fork guiding mechanism for a film raw material transfer forklift includes a guiding assembly 1, which is used to fit onto the fork a. The guiding assembly 1 includes a horizontal part 101 and a flat transition part 102 connected to the horizontal part 101. The horizontal part 101 has a chamber 1011 and a locking member. The chamber 1011 allows the horizontal part 101 to be fitted onto the fork a, and the locking member locks the horizontal part 101 on the fork a, thus maintaining a stable fitting state. The flat transition part 102 has a transition slope 1021. The top end of the transition slope 1021 is flush with the horizontal part 101, and the bottom end is flush with the ground. The transition slope 1021 allows for a smooth transition between the ground and the top surface of the horizontal part 101, eliminating the gap between the fork a and the ground.

[0038] After the guide assembly 1 is fitted onto the fork a, during operation, the fork a first drives the guide assembly 1 downwards towards the ground until the bottom surface of the transition section 102 is in contact with the ground. At this point, the bottom end of the transition ramp 1021 is flush with the ground. As the fork a subsequently moves towards the raw material, the bottom end of the transition ramp 1021 will first contact the raw material. As the fork a continues to move, the transition ramp 1021 allows the raw material to move smoothly onto the fork a, achieving transfer. This application, through the setting of the guide assembly 1 and the flush bottom end of the transition ramp 1021 with the ground, eliminates the previous gap between the fork a and the ground, allowing the raw material to move smoothly onto the fork a without causing excessive compression.

[0039] When fork a needs to transfer other types of raw materials, the locking mechanism can be released from the horizontal part 101, and then the horizontal part 101 can be removed from fork a, thus disassembling the guide assembly 1 and allowing fork a to transfer the corresponding raw materials. In other words, the presence of the guide assembly 1 in this application changes the original transfer target of fork a. When other types of raw materials need to be transferred later, only the guide assembly 1 needs to be disassembled, without modifying fork a to increase its range of operation.

[0040] Furthermore, in order to improve the guiding effect of the transition slope 1021 on the raw materials, this application provides a plurality of assist rollers 1022 rotating along the slope direction on the transition slope 1021. The smooth loading and unloading of raw materials can be achieved by using the rolling assistance of the plurality of assist rollers 1022.

[0041] Since the fork a lifts the material by relying on its top surface when it is working, the locking device in this application is located on the side of the horizontal part 101 in order to avoid interfering with the lifting operation of its top surface.

[0042] Example 1:

[0043] like Figure 3 As shown, the locking mechanism includes fastening bolts 2 located on the side of the horizontal part 101, with one end of the fastening bolts 2 extending into the cavity 1011. Multiple fastening bolts 2 are provided and evenly distributed on both sides of the horizontal part 101. The multiple fastening bolts 2 form an adjustable clamping area between their ends located in the cavity 1011. After the horizontal part 101 is fitted onto the fork a by relying on the cavity 1011, the size of the clamping area is adjusted so that it clamps the fork a, thereby realizing the installation of the horizontal part 101 on the fork a.

[0044] Example 2:

[0045] Or, such as Figure 4 As shown, the locking device can also include a shaft 3 rotatably mounted on the horizontal part 101, with one end of the shaft 3 extending into the chamber 1011. A bidirectional threaded rod 4 is rotatably mounted inside the chamber 1011 and is connected to the shaft 3 in a transmission manner. The bidirectional threaded rod 4 has two threaded sections with opposite threads. A groove 11 is provided on the inner wall of the chamber 1011, and two sets of clamping blocks 5 are slidably mounted on the groove 11. The two clamping blocks 5 are threaded onto the two threaded sections respectively. When the shaft 3 is driven to rotate, the rotation of the shaft 3 can drive the bidirectional threaded rod 4 to rotate. Therefore, the two clamping blocks 5 will move closer to or further away from each other, that is, the two clamping blocks 5 form an adjustable clamping area. By locking the position of the shaft 3 at this time, the stability of the clamping area at this time is ensured. After the horizontal part 101 is fitted onto the fork a via the chamber 1011, the size of the clamping area is adjusted to clamp the fork a, thus achieving the installation of the horizontal part 101 on the fork a. To ensure the stability of the installation, the shaft 3, the bidirectional threaded rod 4, and the two clamping blocks 5 together form a clamping structure. The clamping structure is configured in multiple sets, which are evenly distributed on both sides of the horizontal part 101. Preferably, the clamping structure is configured in two sets and evenly distributed on both sides of the horizontal part 101.

[0046] The transmission connection between the central shaft 3 and the bidirectional threaded rod 4 can be any form in the prior art, such as gear transmission. A first bevel gear 6 is provided at one end of the shaft 3 located in the cavity 1011, and a second bevel gear 7 is provided on the bidirectional threaded rod 4, so that the second bevel gear 7 meshes with the first bevel gear 6 to achieve the transmission connection between the two.

[0047] Compared to the former, the latter's locking mechanism uses four sets of clamping blocks 5 to clamp and fix the top and bottom surfaces of the fork a, making its overall clamping method more stable than the former's clamping method on the side of the fork a.

[0048] like Figures 6-7 As shown, further, when the top surface of the fork a is a conventional inclined design in the prior art, in order to ensure that the clamping block 5 can have a good clamping effect on the top surface of the fork a, the bottom surface of the clamping block 5 can be inclined to match the slope of the top surface of the fork a, so that the bottom surface of the clamping block 5 and the top surface of the fork a are in surface contact, thereby further improving the clamping effect of the clamping block 5 on the fork a.

[0049] like Figures 4-5 As shown, the position locking of the shaft 3 can be achieved using conventional techniques in the prior art, such as locking bolts or mortise locks 8. Taking the mortise lock 8 as an example, the mortise lock 8 includes a cylindrical body 801 fixedly mounted on the horizontal part 101, and the cylindrical body 801 is arranged radially along the shaft 3. A pin 802 that slides along its length is movably inserted inside the cylindrical body 801. Correspondingly, a slot is provided on the outside of the shaft 3 for the pin 802 to be inserted. Figure 4 In the state shown, the clamping area composed of the four clamping blocks 5 clamps the fork a. In this state, the slot is located directly below the pin 802. By sliding the pin 802 on the cylinder 801 downward, it can be inserted into the slot to lock the position of the shaft 3. The shaft 3 cannot rotate, thus achieving stable holding of the clamping area.

[0050] For example Figure 4As shown, during the process of the horizontal part 101 being fitted onto the fork a by the chamber 1011, a locking mechanism can be used to lock the horizontal part 101 in place to remind the operator that it has been fitted. This application also includes a limiting assembly, which includes brackets 9 respectively disposed on the top and bottom inner walls of the chamber 1011. Limiting rollers 10 are rotatably mounted on the brackets 9, forming a fitting area between the two limiting rollers 10. The distance between the two fitting areas is the same as the thickness of a certain cross-section of the fork a. Therefore, during the process of the horizontal part 101 being fitted onto the fork a, the fitting area will also be fitted onto the outside of the fork a. When the fitting area moves to a position with the same thickness as the corresponding cross-section of the fork a, the upper and lower limiting rollers 10 respectively abut against the top and bottom surfaces of the fork a. That is, at this time, the position of the horizontal part 101 on the fork a will be limited, indicating that the horizontal part 101 has moved into place and the subsequent locking mechanism can be used for tightening.

[0051] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
