Description

Technical Field

[0001] This invention belongs to the field of material conveying technology, and relates to a conveying feeder, particularly a uniform thickness vibrating smooth conveying feeder. Background Technology

[0002] Material conveying is indispensable in factory production processes. As a unit operation, its importance in production is self-evident. Existing vibrating conveyor equipment mainly relies on direct drive of elastic leaf springs, such as motor drive or electromagnetic drive. This drive method often results in inconsistent amplitudes at the inlet and outlet ends of the conveying trough, with the outlet amplitude being larger than the inlet amplitude. This leads to greater material agitation at the outlet, which can easily cause damage to some materials during the large-amplitude conveying process from the outlet direction. In addition, existing vibrating conveyor equipment is heavy and has a complex and cumbersome structure. The vibration of the entire machine can cause significant vibrations in the support frame, which can affect the weighing accuracy of related equipment and weighing devices. Summary of the Invention

[0003] The purpose of this invention is to provide a uniform thickness vibrating smooth conveying feeder to solve the technical problems existing in the prior art, such as complex and bulky structure of vibrating conveying equipment, excessive material jump in the conveying trough, unstable conveying, and excessive vibration of the support caused by the vibration of the whole machine during material conveying.

[0004] To achieve the above objectives, the specific technical solution of the present invention is as follows:

[0005] A uniform thickness vibrating smooth conveying feeder includes a working mass and a uniform thickness vibration driving mechanism. The working mass includes a connecting base plate, an elastic leaf spring, and a conveying trough connected sequentially from bottom to top. The uniform thickness vibration driving mechanism is connected to the connecting base plate. The line connecting the center of gravity of the uniform thickness vibration driving mechanism and the center of gravity of the conveying trough is the driving line. The extension direction of the driving line is perpendicular to the body of the elastic leaf spring.

[0006] The equal thickness vibration drive mechanism includes a power driver and an intermediate connecting plate. The lower end of the intermediate connecting plate is connected to the connecting base plate. The main body of the intermediate connecting plate is parallel to the main body of the elastic leaf spring. The power driver is vertically fixed on the intermediate connecting plate.

[0007] The number of elastic leaf springs is two or more, and each elastic leaf spring is arranged in parallel with each other and welded or bolted to the conveying trough and the connecting base plate.

[0008] The conveying trough is a long trough in the form of a round tube or a square trough.

[0009] The intermediate connecting plate and the connecting base plate are connected by welding or bolting.

[0010] The number of equal thickness vibration drive mechanisms is one or more, and the power source of the power drive in each group of equal thickness vibration drive mechanisms is a motor, pneumatic or electromagnetic vibration.

[0011] It also includes shock-absorbing components disposed below the connecting base plate, wherein the number of shock-absorbing components is four or more, evenly distributed at the four corners and the center of the lower part of the connecting base plate.

[0012] During operation, the vibration frequency of the equal-thickness vibration drive mechanism is lower than the vibration frequency of the working mass.

[0013] The beneficial effects of this invention are as follows: This invention provides a uniform thickness vibrating smooth conveying feeder. The invention has a compact and simple structure, and a small overall weight. By setting the line connecting the center of gravity of the waiting vibration drive mechanism and the center of gravity of the conveying trough to be perpendicular to the main body of the elastic leaf spring, and by setting an intermediate connecting plate parallel to the elastic leaf spring, the power drive can drive the intermediate connecting plate and the elastic leaf spring to produce a tuning fork vibration effect during operation. At this time, the connecting bottom plate is the dead point of the tuning fork, and the vibration amplitude is extremely small. This reduces the vibration of the entire feeder, reduces the vibration impact on related equipment and weighing equipment, and improves the weighing accuracy of the weighing equipment. A shock-absorbing component is set below the connecting bottom plate to provide shock absorption for the entire machine, further reducing the vibration transmission between the entire machine and other related equipment, thereby achieving the technical effect of extremely small amplitude vibration at the connection between the bottom of the machine and other related equipment.

[0014] Furthermore, during material transportation, the vibration frequency of the working mass decreases due to the weight of the material. If the frequency of the working mass is equal to or less than the frequency of the equal-thickness vibration drive mechanism, the frequency difference between the two will be too large after the material is transported, and the amplitude difference between the inlet and outlet of the conveying trough cannot be reduced. Based on this actual situation, this invention sets the vibration frequency of the equal-thickness vibration drive mechanism to be less than a certain value of the working mass frequency during actual material transportation, so that the frequency of the working mass is reduced to be consistent with or close to the vibration frequency of the equal-thickness vibration drive mechanism when the material passes through the conveying trough. This enables the amplitude of the material at the inlet and outlet of the conveying trough to be consistent, forming equal-thickness vibration, effectively preventing the material from being damaged at the outlet due to excessive amplitude.

[0017] To better understand the purpose, structure, and function of this invention, the invention will be described in further detail below with reference to the accompanying drawings.

[0018] like Figure 1 As shown, this invention provides a uniform thickness vibrating smooth conveying feeder, which includes a working mass and a uniform thickness vibration drive mechanism. The uniform thickness vibration drive mechanism drives the working mass to perform uniform thickness vibration. Specifically, the working mass includes a connecting base plate 4, an elastic leaf spring 3, and a conveying trough 1 connected sequentially from bottom to top. The uniform thickness vibration drive mechanism includes a power driver 2 and an intermediate connecting plate 6. The lower end of the intermediate connecting plate 6 is connected to the connecting base plate 4. The main body of the intermediate connecting plate 6 is parallel to the main body of the elastic leaf spring 3. The power driver 2 is vertically fixed on the intermediate connecting plate 6. The line connecting the center of gravity of the power driver 2 and the center of gravity A of the conveying trough is the drive line C. The extension direction of the drive line C is perpendicular to the main body of the elastic leaf spring 3, so that the power driver 2 drives the elastic leaf spring 3 and the intermediate connecting plate 6 to form a tuning fork vibration during the driving process, effectively driving the conveying trough 1 to convey materials. At the same time, the above arrangement also makes the connecting base plate 4 a tuning fork dead point, with minimal vibration.

[0019] In addition, to maintain a relatively stable vibration amplitude of the material within the conveying trough and achieve uniform thickness vibration, thus preventing material breakage due to gradually increasing amplitude, in this embodiment, before the initial material conveying, the vibration frequency of the power drive 2 needs to be pre-adjusted to be lower than the vibration frequency of the working mass. Then, the material is fed into the conveying trough 1 at the actual production conveying speed. By measuring the vibration frequency of the conveying trough 1 and the vibration frequency of the power drive 2, the vibration frequency of the power drive 2 is continuously adjusted. When the measured vibration frequency of the conveying trough 1 and the vibration frequency of the power drive 2 are consistent or close, the vibration amplitudes at the inlet and outlet ends of the conveying trough 1 are the same or close. At this point, uniform thickness vibration is formed within the conveying trough 1. Using uniform thickness vibration to convey the material effectively reduces the breakage rate and improves the integrity rate of the material during conveying. It should also be noted that the difference between the vibration frequencies of the power drive 2 and the working mass in the air-operated state when uniform thickness vibration is formed in the conveying trough is affected by the type of power drive 2 component and has no specific range or ratio. The specific difference needs to be adjusted based on the measured indicators.

[0020] Furthermore, to ensure a stable setting of the conveying trough and provide it with effective vibration, the number of elastic leaf springs 3 is two or more. Each elastic leaf spring 3 is arranged parallel to each other and welded or bolted to the conveying trough body 1 and the connecting base plate 4. Preferably, in this embodiment, the number of elastic leaf springs 3 is two. The material and form of the conveying trough body 1 can be various, such as round tubes or square troughs, and are specifically designed according to the material to be conveyed. The intermediate connecting plate 6 is welded or bolted to the connecting base plate 4. In this embodiment, to facilitate component replacement, the conveying trough, elastic leaf springs 3, and connecting base plate 4 are bolted together, with the intermediate connecting plate 6 bolted to the connecting base plate 4.

[0021] Furthermore, the number of equal thickness vibration drive mechanisms can be set to one or more groups according to the actual needs of material conveying. The power source of the power driver 2 in each group of equal thickness vibration drive mechanisms can be a variety of forms such as motor drive, pneumatic drive or electromagnetic drive. In this embodiment, the number of equal thickness vibration drive mechanisms is one group and the drive form is electromagnetic drive.

[0022] Furthermore, the equal-thickness vibrating smooth conveying feeder in this embodiment also includes a shock-absorbing component 5 disposed below the connecting base plate 4. The number of shock-absorbing components 5 is four or more, evenly distributed at the four corners and the center of the lower part of the connecting base plate 4. In this embodiment, since the vibration amplitude of the connecting base plate 4 is extremely small, it is only necessary to set one shock-absorbing component 5 at each of the four corners below it. The shock-absorbing component 5 in this embodiment is a shock absorber. The type of shock absorber can be determined by the technician according to the type of material to be conveyed by the feeder and the instantaneous conveying volume. No specific limitation is made in this embodiment.
