Description

Technical Field

[0001] This utility model relates to the field of automated material conveying technology, and specifically to a spindle belt lifting hopper. Background Technology

[0002] In machining, automotive parts assembly, and other fields, mandrel-type workpieces (such as cylindrical bushings and transmission mandrels) are common basic components. Their production and assembly require specialized equipment for batch transport, temporary storage, and lifting to connect upstream and downstream processes and meet the cycle time requirements of automated production lines. Currently, the industry primarily uses traditional silos combined with manual assistance or simple mechanical structures for mandrel transport and lifting. However, as production lines demand higher efficiency, precision, and automation, existing technologies are increasingly revealing shortcomings and failing to meet actual production needs. Specific problems include: Currently, mandrel conveying relies heavily on manual labor to move the mandrels into the hopper. Although some simple equipment is equipped with a conveying structure, the mandrels still need to be manually arranged to avoid accumulation and jamming. The lifting process also often requires manual adjustment of the mandrel position to match the material handling mechanism. The entire process involves many manual steps, which is not only labor-intensive but also prone to causing the material feeding rhythm to be disordered due to human operation errors. It is difficult to match the high-speed rhythm of automated production lines. Each person can only supervise one piece of equipment, resulting in high labor costs. Utility Model Content

[0003] This invention provides a mandrel belt lifting hopper to solve the problems of the prior art.

[0004] The objective of this utility model can be achieved through the following technical solution: A mandrel belt lifting hopper includes: a frame, a hopper mounted on the frame, and a lifting mechanism mounted on the hopper. The hopper is equipped with a belt conveyor module, which includes a drive mechanism mounted on the side of the hopper, drive rollers rotatably mounted on both ends of the hopper, and a belt sleeved between the two drive rollers. The lifting mechanism includes a temporary storage hopper located at the front end of the hopper and a lifting assembly located at the front end of the temporary storage hopper. The temporary storage hopper is connected to the interior of the hopper and is inclined downwards towards the side away from the hopper. A lifting groove is provided on the side of the temporary storage hopper away from the hopper. The lifting assembly includes a lifting cylinder located outside the temporary storage hopper and a lifting plate fixed to the end of the piston rod of the lifting cylinder. The lifting plate is slidably mounted in the lifting groove of the temporary storage hopper. At least two sets of L-shaped temporary storage racks are provided on the side of the temporary storage hopper away from the hopper.

[0005] In a further improvement, the hopper is provided with a width adjustment mechanism. The adjustment mechanism includes mounting plates on both sides of the hopper, an adjustment rod connected between the two mounting plates, a locking seat slidably mounted on the adjustment rod, and a limiting plate at the lower end of the locking seat. The limiting plate extends into the hopper and is located above the belt.

[0006] In a further improvement, a locking groove is provided through the upper end of the locking seat, and a locking bolt is threaded to the side end of the locking groove. The end of the locking bolt can abut against the outer circumferential surface of the adjusting rod to lock the position of the locking seat.

[0007] In a further improvement, the upper end of the lifting plate is inclined toward the L-shaped temporary storage rack, and a V-shaped positioning groove is provided on the bearing surface of the L-shaped temporary storage rack, the V-shaped positioning groove being adapted to the inclination direction of the lifting plate.

[0008] In a further improvement, a positioning mechanism is provided on the side of the temporary storage bin away from the silo. The positioning mechanism includes a positioning plate and a positioning cylinder, which are symmetrically arranged on both sides of the temporary storage bin.

[0009] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model automatically conveys the mandrel via belt, arranges it by gravity in a temporary storage bin, and lifts it by a lifting cylinder. The entire process requires no manual handling, arrangement, or manual adjustment of the mandrel position, greatly reducing the number of manual intervention steps. The conveying, arranging, lifting, and temporary storage processes can be completed simply by starting the equipment, reducing reliance on operator skills and reducing labor intensity, and adapting to the cycle time of automated production lines. 2. The width of the lifting plate of this utility model is matched with the diameter of a single mandrel, ensuring that each lifting action only acts on one mandrel, effectively avoiding jamming, collision or material handling chaos caused by lifting multiple mandrels at the same time. With the help of a predetermined height trigger electrical switch, the lifting stroke can be controlled to prevent over-lifting from damaging the mandrel or under-lifting from affecting the transfer, thereby improving the efficiency of mandrel handling. 3. The temporary storage bin of this utility model guides the mandrels to automatically arrange themselves by gravity, avoiding the squeezing and deformation caused by the random accumulation of mandrels. After the mandrels are lifted, they slide into the L-shaped temporary storage rack by gravity without rigid pushing, reducing friction and collision between the mandrels and components, and ensuring the appearance and structural integrity of the mandrels. It is especially suitable for mandrel-type workpieces with high surface precision requirements. 4. The belt conveyor and lifting action of this utility model can be continuously coordinated. The temporary storage bin temporarily stores the mandrel and the L-shaped temporary storage rack is ready for retrieval. The next round of conveying and lifting can be started without waiting for the hoisting mechanism to pick up the material. This reduces the downtime of the production line caused by material supply interruption. The lifting cylinder resets quickly, further shortening the single cycle and helping to improve the overall production efficiency. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0013] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0014] The following is a description of the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.

[0015] Example 1 A mandrel belt-driven lifting hopper includes: a frame 1, a hopper 2 mounted on the frame 1, and a lifting mechanism 3 mounted on the hopper 2. The hopper 2 is equipped with a belt conveyor module 4, which includes a drive mechanism 41 located at one side of the hopper 2, drive rollers 42 rotatably mounted at both ends of the hopper 2, and a belt 43 sleeved between the two drive rollers 42. The lifting mechanism 3 includes a temporary storage bin 31 located at the front end of the hopper 2 and a lifting assembly 3 located at the front end of the temporary storage bin 31. 2. The temporary storage bin 31 is internally connected to the silo 2 and is inclined downwards towards the side away from the silo 2. The temporary storage bin 31 is provided with a lifting groove on the side away from the silo 2. The lifting assembly 32 includes a lifting cylinder 321 located outside the temporary storage bin 31 and a lifting plate 322 fixed to the end of the piston rod of the lifting cylinder 321. The lifting plate 322 is slidably assembled in the lifting groove of the temporary storage bin 31. At least two sets of L-shaped temporary storage racks 5 are provided on the side of the temporary storage bin 31 away from the silo 2.

[0016] like Figures 1-4 As shown, the usage process of this utility model is as follows: First, place the mandrel into the hopper 2 and start the drive mechanism 41. The drive mechanism drives the belt 43 to rotate. The belt 43 transports the mandrel in the hopper 2 to the temporary storage hopper 31. After the mandrel enters the temporary storage hopper 31, it automatically and orderly arranges itself under the action of gravity, avoiding messy accumulation. Secondly, the lifting cylinder 321 is activated, and its piston rod drives the lifting plate 322 to move. Since the width of the lifting plate 322 matches the diameter of a single spindle, it can only lift the spindle at the very front of the temporary storage chamber 31. Secondly, when the mandrel is lifted to the predetermined height, the electrical switch is triggered, the lifting cylinder 321 stops lifting, and the mandrel slides from the lifting plate 322 into the L-shaped temporary storage rack 5 under the action of gravity for temporary storage. Finally, the piston rod of the lifting cylinder 321 retracts, driving the lifting plate 322 to reset. Then, the hoisting mechanism grabs the mandrel on the L-shaped temporary storage rack 5 to complete the material removal, and the equipment enters the next cycle.

[0017] This utility model has the following beneficial effects: 1. The mandrel is automatically conveyed via belt 43, arranged by gravity in temporary storage bin 31, and lifted by lifting cylinder 321. The entire process requires no manual handling, arrangement, or adjustment of the mandrel position, significantly reducing manual intervention. The entire process of conveying, arranging, lifting, and temporary storage can be completed simply by starting the equipment, reducing reliance on operator skills, minimizing labor intensity, and adapting to the cycle time of automated production lines. 2. The 322 width of the lifting plate matches the diameter of a single mandrel, ensuring that each lifting action only affects one mandrel, effectively avoiding jamming, collision, or material handling chaos caused by lifting multiple mandrels simultaneously. With the help of a preset height trigger electrical switch, the lifting stroke can be controlled to prevent damage to the mandrel from over-lifting or insufficient lifting from affecting transfer, thus improving the efficiency of mandrel handling. 3. The temporary storage compartment 31 guides the mandrels to automatically arrange themselves by gravity, avoiding the squeezing and deformation caused by the random accumulation of mandrels. After the mandrels are lifted, they slide into the L-shaped temporary storage rack 5 by gravity without rigid pushing, reducing friction and collision between the mandrels and components, and ensuring the appearance and structural integrity of the mandrels. It is especially suitable for mandrel-type workpieces with high surface precision requirements. 4. The belt conveyor and lifting action can be continuously coordinated. The temporary storage bin 31 temporarily stores the mandrel and the L-shaped temporary storage rack 5 is ready for retrieval. The next round of conveying and lifting can be started without waiting for the hoisting mechanism to pick up the material, reducing the downtime of the production line caused by material supply interruption. The lifting cylinder 321 resets quickly, further shortening the single cycle and helping to improve the overall production efficiency.

[0018] As a further preferred embodiment, the hopper 2 is provided with a width adjustment mechanism 6. The adjustment mechanism 6 includes mounting plates 61 on both sides of the hopper 2, an adjustment rod 62 connected between the two mounting plates 61, a locking seat 63 slidably mounted on the adjustment rod 62, and a limiting plate 64 at the lower end of the locking seat 63. The limiting plate 64 extends into the hopper 2 and is located above the belt 43.

[0019] Specifically, the sliding locking seat 63 moves along the adjusting rod 62, which can drive the limiting plate 64 to adjust the spacing so that the width between the two limiting plates 64 matches the diameter of the mandrel. The limiting plate 64 extends into the hopper 2 and is located above the belt 43. It can limit the mandrel on both sides during the conveying process, preventing the mandrel from shifting or rolling due to belt vibration or uneven load. It can adapt to multiple specifications of mandrels without changing the hopper, greatly improving the versatility of the equipment, while ensuring the stability of the conveying process and reducing the risk of jamming caused by mandrel offset.

[0020] As a further preferred embodiment, the upper end of the locking seat 63 is provided with a locking groove 631, and the side end of the locking groove 631 is threaded with a locking bolt 632. The end of the locking bolt 632 can abut against the outer peripheral surface of the adjusting rod 62 to lock the position of the locking seat 63.

[0021] Specifically, after adjusting the spacing of the limit plate 64, tighten the locking bolt 632 so that its end abuts against the outer circumference of the adjusting rod 62. This can firmly lock the locking seat 63 through friction, preventing the locking seat from shifting due to vibration or collision during spindle conveying, ensuring the stability of the limit width. Loosening the bolt allows for quick adjustment of the position, making the operation simple and balancing adjustment flexibility with fixation reliability.

[0022] As a further preferred embodiment, the upper end of the lifting plate 322 is inclined toward the L-shaped temporary storage rack 5, and a V-shaped positioning groove is provided on the bearing surface of the L-shaped temporary storage rack 5, the V-shaped positioning groove being adapted to the inclination direction of the lifting plate 322.

[0023] Specifically, the upper end of the lifting plate 322 is inclined toward the L-shaped temporary storage rack 5, which can guide the mandrel smoothly from the lifting plate to the temporary storage rack with the help of gravity, reducing jamming or stagnation during the transfer of the mandrel and improving the smoothness of the transfer; the V-shaped positioning groove of the L-shaped temporary storage rack 5 is adapted to the tilt direction of the lifting plate, which can limit the sliding mandrel. The V-shaped structure automatically corrects the position of the mandrel through the inclined surfaces on both sides, preventing the mandrel from rolling and shifting on the temporary storage rack, ensuring accurate positioning when the subsequent hoisting mechanism grabs it, reducing grabbing failures caused by mandrel displacement, and improving material handling efficiency.

[0024] As a further preferred embodiment, a positioning mechanism 7 is provided on the side of the temporary storage bin 31 away from the hopper 2. The positioning mechanism 7 includes a positioning plate 71 and a positioning cylinder 72, which are symmetrically arranged on both sides of the temporary storage bin 31.

[0025] Specifically, the positioning plate 71 and the positioning cylinder 72 are used to position the mandrel on the V-shaped positioning groove, correcting any slight offset of the mandrel within the V-shaped groove. This also ensures that the mandrel axis is aligned with the material handling reference of the lifting mechanism, effectively avoiding problems such as lifting misalignment and gripping failure caused by placement deviations of the mandrel. The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
