Description

Technical Field

[0001] This utility model relates to the field of sheet-laying and tube-expanding machine technology, and in particular to a hopper and sheet-laying mechanism for an automatic sheet-laying and tube-expanding machine. Background Technology

[0002] Traditional automatic finning and expanding machines use a flat hopper structure. A cylinder mounted at the rear of the hopper pushes the fins together. However, this design suffers from difficulties in adjusting the cylinder's thrust. Excessive or insufficient thrust on the fins affects the finning efficiency. Furthermore, fine-tuning the cylinder's thrust may be necessary when handling large or small quantities of fins. Since the machine uses compressed air, fluctuations in compressed air pressure also affect finning performance. Because of a fixed dead stop in the middle of the flat hopper, it cannot accommodate the simultaneous production of one long fin or two short fins. Therefore, continuous operation is not possible when adding fins; the finning process must be stopped before installation.

[0003] In addition, the existing finning mechanism can only produce two short fin products of the same type at a time, which is not very versatile. Summary of the Invention

[0004] The technical problem to be solved by this utility model is: in order to solve the problems existing in the prior art in the background art, a material bin and a sheet feeding mechanism for an automatic sheet feeding and tube expanding machine are provided.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a hopper and a hopper mechanism for an automatic sheet-distributing and tube-expanding machine, including a hopper mechanism and a hopper mechanism.

[0006] The silo mechanism includes a base plate and a multi-layer material rack on the base plate. The multi-layer material rack includes multiple storage plates distributed vertically. The storage plates have inclined sections and horizontal sections. Several blocks are detachably connected to the storage plates to form a material channel for placing fins. The material channel is provided with a pusher bar that abuts against the fins. A baffle strip that limits the fins is provided on the outer side of the horizontal section of the storage plate.

[0007] The stacking mechanism includes a gantry frame, a lifting assembly, a telescopic assembly, and a suction assembly. The lifting assembly is vertically mounted on the gantry frame, the telescopic assembly is mounted on the lifting assembly, and the suction assembly is connected to the telescopic assembly.

[0008] Furthermore, the multi-layer material rack also includes a front support frame and a rear support frame. The front support frame includes a mandrel and multiple mounting plates and a top plate mounted on the mandrel from bottom to top. The horizontal section of the storage plate is connected to the mounting plate.

[0009] Furthermore, spacers are fitted onto the mandrels between adjacent mounting plates.

[0010] Furthermore, an upper baffle is connected to the outer end of the top plate corresponding to the material channel, and a lower baffle and an upper baffle are connected sequentially from top to bottom to the outer end of the mounting plate corresponding to the material channel. A lower baffle is connected to the outer end of the bottom plate corresponding to the material channel.

[0011] Furthermore, the rear support frame includes two uprights and multiple crossbars, with each end of the crossbar connected to one of the two uprights, and the uprights fixed to the base plate.

[0012] Furthermore, one end of the inclined section of the storage plate rests on the crossbar.

[0013] Furthermore, baffles are connected to both sides and one end of the base plate, and support pillars connected to the bed frame are provided at the four corners of the bottom surface of the base plate.

[0014] Furthermore, the lifting assembly includes a servo motor, a lead screw, a lead screw nut, and a guide rail. The servo motor is installed on the upper part of the gantry frame, and its output end is connected to one end of the lead screw. The other end of the lead screw is movably connected to the lower part of the gantry frame. The lead screw nut is connected to the telescopic assembly. The guide rail is vertically installed on both sides of the gantry frame, and a slider is provided on the guide rail that slides up and down along it. The slider is connected to the telescopic assembly.

[0015] Furthermore, the telescopic assembly includes a slide plate, a telescopic plate, a cylinder, and a guide post. The lead screw nut is connected to the slide plate via a connecting seat. The cylinder is mounted on the slide plate, and its push rod passes through the slide plate and connects to the telescopic plate. A guide post is connected to the telescopic plate, and the guide post passes through the slide plate. A linear bearing is provided between the guide post and the slide plate. A rubber pad is connected to one end of the linear bearing near the telescopic plate. A material suction assembly is connected to the outer side of the telescopic plate.

[0016] Furthermore, the suction assembly includes a suction rack, and an air pipe clamp is provided on the side of the suction rack near the telescopic plate. The air pipe clamp is provided with an air pipe connected to the vacuum generator, and a suction cup connected to the air pipe is provided below the suction rack.

[0017] The beneficial effects of this utility model are as follows: The original flat hopper has been replaced with an inclined hopper, and the fins are now pressed together using the weight of the fins themselves and the weight behind them, instead of a cylinder pushing them. This simplifies the structure, reduces processing costs and cycle time, improves equipment stability, reduces the number of manual adjustments required, and allows for simultaneous fin production and addition, thus increasing production efficiency. The overall length of the equipment is shortened, improving factory utilization. The fin arrangement mechanism, through adjustments to the component structure, can accommodate the production of different types of fins, increasing its versatility. Attached Figure Description

The storage plate 121 is used to place the fins. Its horizontal section 1212 is fixed on the mounting plate 1222. The storage plate 121 is equipped with a stop block 13 to form a flow channel to maintain the position of the fins 3 during operation. The stop block 13 is equipped with a magnet and is fixed to the storage plate 121 by magnetic attraction. The cross bar 1232 of the rear support frame 123 is used to support the tail of the storage plate 121. The lower stop bar 152 and the upper stop bar 151 are used to block the fins 3. The pusher bar 14 is placed behind the fins 3 to apply a downward force to push the fins 3 tight.

[0036] like Figure 5 As shown, the lifting assembly 22 of the stacking mechanism 2 includes a servo motor 221, a lead screw 222, a lead screw nut 223, and a guide rail 224. The servo motor 221 is installed on the upper part of the gantry frame 21, and its output end is connected to one end of the lead screw 222. The other end of the lead screw 222 is movably connected to the lower part of the gantry frame 21. The lead screw nut 223 is connected to the telescopic assembly 23.
