Description

Technical Field

[0001] The utility model relates to the field of material feeding mechanisms, in particular to an anti-blocking material feeding mechanism for a numerical control machining center. Background Art

[0002] At present, a Chinese utility model with announcement number CN208895710U discloses a material feeder for a machining center, including a material feeder hopper, a support plate fixedly connected to the back of the material feeder hopper, a motor fixedly connected to the top of the support plate, a first bearing penetrating the back of the material feeder hopper, an output end of the motor passing through the first bearing and fixedly connected to a rotating rod, a second bearing fixedly connected to the front of the rotating rod, and a front of the second bearing fixedly connected to the front side of the inner wall of the material feeder hopper. The utility model solves the problem of easy material jamming in the existing material feeder for a machining center by using a supporting plate, a motor, a first bearing, a rotating rod, a second bearing, a cylinder and a paddle. The material feeder for the machining center has the advantage of preventing material jamming. During use, it can avoid the phenomenon of jamming due to material agglomeration. Material feeding is rapid, which reduces the difficulty of unblocking for operators and is convenient for operators to use. It is worthy of popularization.

[0003] Although the existing feeding machine is simple to operate and can rotate in the cylinder through the rotating rod, there are still other problems in the use process, such as the lack of material anti-blocking function, the barrel is wide at the top and narrow at the bottom. When too much material is put into the hopper at one time, the material will flow into the narrow section along the wide section of the barrel. In the narrow section, as the space shrinks, it is very easy for the materials to get stuck with each other, increasing the burden of personnel guidance, and it has no buffering function. The material will continue to accelerate during the process of falling from a height. When the bottom of the material in the accelerated state contacts with foreign objects, a collision will occur. If the contact object is rigidly fixed, the material is easily scratched under the interaction of forces, and the safety is low. In order to solve the above-mentioned problems, we propose an anti-blocking feeding mechanism for a CNC machining center. Utility Model Content

[0004] The utility model aims to provide an anti-blocking material feeding mechanism for a numerical control machining center, which solves the problem that the existing material feeding mechanism does not have the material anti-blocking function and does not have the bottom buffering function.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: an anti-blocking unloading mechanism of a CNC machining center, comprising a barrel, a base plate is arranged inside the barrel, a first fixing rod is equidistantly welded between the surface of the base plate and the barrel, a shell is bolted to the bottom of the first fixing rod, a motor is bolted to the inside of the shell, a rotating shaft is fixedly sleeved on the output end of the motor, a scraper is welded to the surface of the rotating shaft through a connecting rod, a bottom plate is arranged at the bottom of the barrel, a second fixing rod is welded between the top of the bottom plate and the barrel, a mounting groove is opened at the top of the bottom plate, a buffer plate is arranged inside the mounting groove, a fixing spring is bolted between the bottom of the buffer plate and the mounting groove through a spring fixing sheet, and a damper is installed between the bottom of the buffer plate and the mounting groove.

[0006] The above technical solution can have the function of preventing materials from being blocked, thus preventing materials from accumulating in the narrow section inside the barrel when falling, reducing the burden of personnel in clearing the way. At the same time, it can have the function of bottom buffering, which can greatly reduce the impact force generated when materials fall, thus ensuring the safety of materials and having high practicality.

[0007] The utility model is further configured as follows: a material guide block is installed on the top of the base plate, and the top end of the material guide block is conical.

[0008] By adopting the above technical solution, the material can be guided by setting the material guide block, so that the material falling onto the substrate slides downward from all sides.

[0009] The utility model is further configured as follows: ventilation holes are provided on the surface of the shell.

[0010] By adopting the above technical solution and setting the ventilation holes, the ventilation effect inside the shell can be improved.

[0011] The utility model is further configured as follows: the base plate, the first fixing rod and the scraper are all made of stainless steel.

[0012] By adopting the above technical solution, the base plate, the first fixing rod and the scraper have the characteristics of high strength, low density and excellent corrosion resistance.

[0013] The utility model is further configured as follows: a limiting rod is welded to the bottom of the buffer plate, and the other end of the limiting rod penetrates and extends to the bottom of the base plate.

[0014] By adopting the above technical solution, the buffer plate can be limited by setting the limiting rod to prevent the buffer plate from tilting during the process of moving up and down.

[0015] The utility model is further configured as follows: a guide cylinder is bolted to the bottom end of the barrel surface.

[0016] By adopting the above technical solution, the buffered material can be guided by setting the guide cylinder to avoid the material being scattered after falling.

[0017] The utility model is further configured as follows: the fixing spring is made of carbon spring steel.

[0018] By adopting the above technical solution, the fixed spring has the characteristics of excellent mechanical properties, good anti-elasticity, low temperature resistance and corrosion resistance.

[0019] In summary, the utility model has the following beneficial effects:

[0020] 1. The utility model fixes the barrel at a specified position first, and starts the motor when the material enters the barrel. After starting, the motor drives the rotating shaft to rotate through the fixed lower part of the shell. The rotating shaft drives the connecting rod and the scraper to rotate when rotating. The connecting rod and the scraper will dredge the material when rotating, and can have the function of preventing the material from clogging, avoiding the accumulation of the material in the narrow section inside the barrel when falling, and reducing the burden of personnel dredging.

[0021] 2. According to the utility model, the material coming out from the bottom of the barrel will first fall onto the buffer plate. After the material collides with the buffer plate, the buffer plate will move downward. When the buffer plate moves downward, it will press the fixed spring and the damper. When the fixed spring is compressed and enters a contracted state, it will absorb the falling force of the material. Finally, the material after unloading will slide from the top of the buffer plate. It can have a bottom buffering function, which can greatly reduce the impact force generated when the material falls, thereby ensuring the safety of the material and having high practicality.
