Description

Technical Field

[0001] This utility model relates to the field of unloading technology, and in particular to an unloading conveyor device. Background Technology

[0002] The manual unloading method for tobacco refers to the process in the tobacco logistics and distribution chain where, after a truck fully loaded with tobacco pouches arrives at the tobacco company's warehouse, multiple workers work together to unload the stacked tobacco pouches one by one using a relay method and place them onto a conveyor belt, which then transports the tobacco pouches to a designated location for stacking.

[0003] In existing technologies, the unloading of fully loaded, high-stapled tobacco pouches from trucks is generally done manually. While this method can accomplish the task of unloading high-stapled tobacco pouches, it has significant drawbacks: First, the operation requires a large amount of manpower, with workers frequently bending over, lifting, and turning, resulting in extremely high labor intensity, time-consuming, and inefficient work. Second, because the tobacco pouches themselves have a certain weight and need to be manually passed from a height, they are prone to slipping or falling due to unstable grip, coordination errors, or physical exhaustion, posing a serious safety threat to workers below (such as at the bottom of the truck bed or on the ground), posing a risk of injury from falling objects, and resulting in poor operational safety.

[0004] The above problems highlight the urgent need for an unloading and conveying device to replace manual labor in carrying tobacco pouches and passing them around at heights, thereby ensuring safe unloading. Utility Model Content

[0005] The purpose of this invention is to provide a loading and unloading conveyor device that can replace manual labor to safely and efficiently unload tobacco pouches from high places, significantly reducing labor intensity and the risk of falls.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A loading and unloading conveying device includes a conveying mechanism, the conveying mechanism including side plates located on both sides of a conveyor belt, characterized in that: a guide groove is provided at the lower end of the side plate, a sliding block is slidably disposed along the path of the guide groove, the sliding block is fixedly disposed on the loading and unloading mechanism for diverting tobacco pouches, the guide groove includes a receiving section and a supporting section, when the sliding block is in the receiving section, the diversion surface of the loading and unloading mechanism is parallel to the conveying surface of the conveying mechanism and the loading and unloading mechanism is located at the bottom of the conveying mechanism, when the sliding block is in the supporting section, the diversion surface of the loading and unloading mechanism and the conveying surface of the conveying mechanism form different supporting angles.

[0008] By adopting the above technical solution, the guide channel enables the unloading mechanism to quickly switch between a stowage state (saving space) and a multi-angle working state (adapting to the height of the truck), greatly reducing the need for manual high-altitude transfer.

[0009] The unloading mechanism is further configured such that: the unloading mechanism includes a flow guide plate and an extension plate, the flow guide surface of the extension plate is smoothly connected to the flow guide surface of the flow guide plate, and an adjustment component is provided between the flow guide plate and the extension plate to adjust the length between them.

[0010] By adopting the above technical solution, the diversion plate and the extension plate have an adjustment component to adjust the length between them. The adjustment component can be extended and retracted to match the cargo boxes of trucks of different heights, thus expanding the applicability of the device.

[0011] The adjustment assembly is further configured as follows: a first sliding groove for sliding of the extension plate is provided parallel to the flow surface of the flow plate; a plurality of locking holes are provided at intervals along the length direction of the extension plate; a threaded hole is provided in the flow plate and communicates with the first sliding groove; and a bolt is threadedly connected to the threaded hole and the locking hole in sequence.

[0012] By adopting the above technical solution, the bolt passes through the locking hole and the threaded hole to achieve rapid positioning of the extension plate length, ensuring structural stability.

[0013] The support section is further configured as follows: the support section is a circular path and a plurality of circumferentially spaced angular limiting grooves are provided on the path, and the shape of the angular limiting grooves is adapted to the shape of the sliding block.

[0014] By adopting the above technical solution, the sliding block can be inserted into the limiting groove at different angles to fix the tilt angle of the unloading mechanism and adapt to cargo boxes of different heights.

[0015] The following configuration is further provided: the receiving section is a straight path and a receiving limiting groove is provided at one end of the path away from the support section. The shape of the receiving limiting groove is adapted to the shape of the sliding block, and the path length of the receiving section is greater than the length of the unloading mechanism at its minimum length.

[0016] By adopting the above technical solution, the storage limiting groove locks the unloading mechanism to a completely parallel state, preventing shaking during transportation; the path length of the storage section is greater than the length of the unloading mechanism at its minimum length, ensuring that the extension plate can still be completely stored on the bottom side of the side plate after it is retracted.

[0017] A further configuration is provided: on both sides of the diversion plate, diversion blocks are provided to make the diversion area gradually narrow towards the conveyor belt.

[0018] By adopting the above technical solution, the diversion block concentrates the tobacco bag to slide down to the conveying module, preventing it from shifting and falling, and ensuring the accuracy of unloading.

[0019] The extension plate is further configured such that a push-pull ring for adjusting the extension plate and a hook for attaching to the truck are provided at one end of the extension plate facing away from the conveying mechanism.

[0020] By adopting the above technical solution, the push-pull ring provides a force application point, making it easy for workers to quickly adjust the length and angle of the extension plate; the hook is directly fixed to the edge of the truck bed, ensuring a seamless connection between the unloading mechanism and the truck bed.

[0021] The following configuration is further provided: at least two support legs are provided at the bottom of both the diversion plate and the extension plate. The support legs include a universal joint threadedly connected to the diversion plate and a threaded sleeve threadedly connected to the universal joint. A support pad is fixed at the bottom of the threaded sleeve.

[0022] By adopting the above technical solution, both the diversion plate and the extension plate are threadedly connected to the universal joint for easy installation and use when supporting the tobacco bag, thus playing a supporting role. The height of the support leg can be adjusted by rotating the threaded sleeve, and the tilt angle of the diversion plate and the extension plate can be adaptively adjusted by the universal joint.

[0023] The configuration is further defined as follows: an infrared counter is provided on the side plate, the infrared counter includes a counting sensor and a display screen, and the counting sensor and the display screen are both fixedly installed on the side plate.

[0024] By adopting the above technical solution, infrared sensors automatically count the number of tobacco pouches that have fallen, and the display screen shows the data in real time, replacing manual counting and improving management efficiency. Attached Figure Description

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] refer to Figures 1 to 6 A loading and unloading conveying device includes a conveying mechanism 1. The conveying mechanism 1 includes side plates 11 located on both sides of a conveyor belt. Guide grooves 12 are provided at the lower ends of the outer sides of the two side plates 11. The guide grooves 12 are composed of a straight receiving section 111 and an annular support section 112. A sliding block 13 is slidably arranged on the guide groove 12 along its path. The sliding block 13 is embedded in the guide groove 12 and slides along its path. The flow guide plate 21 of the loading and unloading mechanism 2 is made of stainless steel plate, and its surface is polished to reduce frictional resistance.

[0034] The unloading mechanism 2 includes a diversion plate 21 and an extension plate 22. The diversion surface of the extension plate 22 is smoothly connected to the diversion surface of the diversion plate 21. There is an adjustment component between the diversion plate 21 and the extension plate 22 to adjust the length between them. The bottom of the diversion plate 21 is fixedly connected to the sliding block 13 by a support rod.

[0035] The adjustment assembly includes a first sliding groove 31 parallel to the flow surface of the flow guide plate 21 for the extension plate 22 to slide, a plurality of locking holes 32 spaced apart along the length of the extension plate 22, a threaded hole 33 in the flow guide plate 21 and communicating with the first sliding groove 31, and a bolt 34 threadedly connected to the threaded hole 33 and the locking hole 32 in sequence. The locking hole 32 has a diameter of 6mm, and each locking hole 32 is spaced 100mm apart. The threaded hole 33 is M6.

[0036] The support section 112 is a semi-circular ring with a radius of 150mm. Five angular limiting grooves 41 are evenly distributed around the circumference of the semi-circular ring. The angular limiting grooves 41 are adapted to the rectangular cross-section of the sliding block 13. The receiving section 111 is a straight groove with a receiving limiting groove 51 at the bottom end for completely limiting the sliding block 13. The shape of the receiving limiting groove 51 is adapted to the shape of the sliding block 13. The path length of the receiving section 111 is greater than the minimum length of the unloading mechanism 2, so as to be completely received on the bottom side of the conveying mechanism 1.

[0037] Drainage blocks 6 are welded on both sides of the drainage plate 21. The drainage blocks 6 are made of stainless steel plates and form a funnel-shaped guide area. A push-pull ring 7 is fixedly installed at the end of the extension plate 22 and hooks 8 are fixedly installed on both sides of the push-pull ring 7. The hooks 8 are fixed to the extension plate 22 with bolts 34. The bottom of both the diversion plate 21 and the extension plate 22 are symmetrically provided with two sets of support legs. Each set of support legs includes a universal joint 81, a threaded sleeve 82, and a support foot pad 83. The top of the universal joint 81 is provided with an external threaded post, which is screwed into the pre-set threaded mounting hole at the bottom of the diversion plate 21 to achieve rigid fixation and angle adjustment. The threaded sleeve 82 is machined with an internal thread that matches the external thread at the bottom of the universal joint 81. The sleeve is rotated to drive the universal joint 81 to move up and down axially. The support foot pad 83 is made of wear-resistant rubber and is fixed to the bottom end face of the threaded sleeve 82 by bolts 34. When the unloading mechanism 2 is adjusted to the working angle through the guide groove 12, the universal joint 81 adapts to the ground tilt. The threaded sleeve 82 is manually rotated to make the support foot pad 83 contact the ground and compact it, thus providing support. When storing, the two sets of support legs are disassembled. An infrared counting sensor 91 (detection distance 0-3m) is installed on the outside of the side plate 11, and a display screen 92 is installed on the upper end face of the side plate 11.

[0038] Overall workflow: During the storage phase, release hook 8, disassemble each set of support legs, retract extension plate 22, slide block 13 along storage section 111 into storage limiting groove 51, and guide plate 21 attaches to the bottom of conveyor belt; During the working phase, pull push-pull ring 7 to slide sliding block 13 into support section 112, and select angle limiting groove 41 according to truck height to engage; After loosening adjusting bolt 34, adjust extension plate 22 until it fits against the truck bed, hook 8 fastens to the edge of the truck bed, and install 4 sets of support legs; High-mounted tobacco pouches slide sequentially from extension plate 22 across guide plate 21 onto the conveyor belt of the conveyor module, are guided by guide block 6, and slide along the inclined surface onto the conveyor belt; Counting sensor 91 counts the number of pouches that have fallen and displays it on display screen 92.
