Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal processing technology, and in particular to a feeding device for processing stainless steel bars. Background Technology
[0002] In the processing of stainless steel bars, the bars must first be conveyed to the processing equipment. Existing feeding devices typically only have simple conveying functions and cannot screen the length of the stainless steel bars during the feeding process. This results in some bars of unqualified length entering the processing equipment, which not only affects the quality of the processed products but may also cause the processing equipment to stall, reducing processing efficiency. Therefore, it is necessary to design a feeding device that can screen bars of qualified length during the feeding process. Utility Model Content
[0003] The purpose of this utility model is to provide a feeding device for processing stainless steel bars. In fact, during the feeding process, the length of the bars is measured and screened before being transported in different directions.
[0004] To solve the above-mentioned technical problems, the solution adopted by this utility model is as follows:
[0005] A feeding device for processing stainless steel bars includes a conveyor belt module and a second pushing module arranged in parallel. The two are arranged in parallel. A first pushing module is provided between the conveyor belt module and the second pushing module and facing the second pushing module. A transition ramp is provided between the first pushing module and the second pushing module. A lifting door is provided in the transition ramp.
[0006] The front and rear ends of the conveyor belt module are equipped with contact sensors and laser rangefinders.
[0007] Furthermore, the conveyor belt module includes a horizontal conveyor belt and baffles erected on both sides of the horizontal conveyor belt. The baffle near the second pushing module is provided with a notch connecting to a transition ramp, and the baffle is also provided with another notch connecting to a feeding ramp.
[0008] Furthermore, the second pushing module is set at a height lower than that of the conveyor belt module. The second pushing module includes a slide groove with a V-shaped upward opening and a straight module. A second pushing block is provided in the slide groove, and the second pushing block is fixedly linked with the slide table in the straight module.
[0009] Furthermore, the bottom end of the transition ramp connects to the top end of one side of the chute, and the top end of the transition ramp connects to the upper conveying surface of the horizontal conveyor belt.
[0010] Furthermore, the first pushing module includes ≥2 horizontally positioned telescopic cylinders, the front end of which is connected to a first pushing block facing the transition slope, the first pushing block being located above the upper conveying surface of the horizontal conveyor belt.
[0011] Furthermore, the top surface of the lifting door and the top surface of the transition slope have the same slope. The transition slope is provided with a through opening for the lifting door to be inserted from below until the upper surfaces of the two are level. A lifting power device is connected to the bottom of the lifting door, and a material box is provided below the through opening.
[0012] Furthermore, the through-hole is sized to allow stainless steel bars to pass through and fall into the hopper.
[0013] Furthermore, the second push block includes a base with variable spacing and a push head. The base is provided with a horizontal sliding hole, the push head is connected to a horizontal sliding rod and inserted into the horizontal sliding hole, an elastic compression spring is sleeved around the horizontal sliding rod, and the lower end of the push head is provided with a V-shaped protrusion that is embedded in a sliding groove.
[0014] Furthermore, the conveyor belt module transports the stainless steel bar from the laser rangefinder side to the contact sensor side. When the contact sensor contacts the front end of the stainless steel bar, it sends a signal, and the laser rangefinder works to measure the distance between itself and the rear end of the stainless steel bar.
[0015] Furthermore, the baffle near the second pusher module has a notch and is fitted with an arc-shaped baffle, which narrows a section of the channel between the two baffles.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] This utility model has a reasonable structure, and the feeding, conveying, measuring and screening processes are connected quickly and smoothly. It realizes the measurement and screening of the length of stainless steel bars during the feeding process. Bars that pass the measurement are conveyed to the next stage, while bars that fail the measurement are conveyed to the material box below for collection, which effectively improves processing efficiency and product quality.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0025] See also Figures 1-5 As shown, the feeding device for processing stainless steel bars includes a conveyor belt module 1 and a second pushing module 2 arranged in parallel. The two are arranged in parallel. A first pushing module 3 is arranged between the conveyor belt module 1 and the second pushing module 2 and faces the second pushing module 2. A transition ramp 4 is arranged between the first pushing module 3 and the second pushing module 2. A lifting door 4a is arranged in the transition ramp 4. The action of the lifting door 4a realizes the screening of stainless steel bars.
[0026] To measure the length of stainless steel bars, a contact sensor 5 and a laser rangefinder 6 are installed opposite each other at the front and rear ends of the conveyor belt module 1. The conveyor belt module 1 transports the stainless steel bars from the laser rangefinder 6 side to the contact sensor 5 side. When the contact sensor 5 contacts the front end of the stainless steel bar, it sends a signal. The laser rangefinder 6 then measures the distance l2 between itself and the rear end of the stainless steel bar. Since the distance l1 between the contact sensor 5 and the laser rangefinder 6 is fixed, the length of the stainless steel bar at that point can be obtained by subtracting l1 from l2.
[0027] The conveyor belt module 1 includes a horizontal conveyor belt and baffles erected on both sides of the horizontal conveyor belt. The baffle near the second pusher module 2 is provided with a notch connecting to the transition ramp 4. The baffle is also provided with another notch connecting to the feeding ramp 7.
[0028] The top of the transition ramp 4 is connected to the upper conveying surface of the horizontal conveyor belt. The first pushing module 3 includes ≥2 horizontally placed telescopic cylinders. The front end of the telescopic cylinder is connected to a first push block facing the transition ramp 4. The first push block is located above the upper conveying surface of the horizontal conveyor belt. The first push block extends to push the stainless steel bar that is moving forward onto the transition ramp 4.
[0029] Specifically, the top surface of the lifting door 4a and the top surface of the transition ramp 4 have the same slope. The transition ramp 4 is provided with a through opening for the lifting door 4a to be inserted from below until the upper surfaces of the two are level. A lifting power device 8 is connected to the bottom of the lifting door 4a. A material box 9 is provided below the through opening. The size of the through opening is large enough for stainless steel bars to pass through and fall into the material box 9. The lifting power device 8 can be a telescopic cylinder or an electric cylinder. When it drives the lifting door 4a to descend, the stainless steel bars that have rolled down the transition ramp 4 will fall into the material box 9 through the through opening. When the lifting door 4a blocks the through opening, the stainless steel bars that have rolled down the transition ramp 4 will smoothly reach the second pushing module 2.
[0030] In this embodiment, the height of the second pushing module 2 is lower than that of the conveyor belt module 1. The second pushing module 2 includes a slide 2a with a V-shaped upward opening and a straight module 2c. A second pushing block 2b is provided in the slide 2a. The second pushing block 2b is fixedly linked with the slide table in the straight module 2c. The bottom end of the transition ramp 4 connects to the top end of one side of the slide 2a. After the stainless steel bar moves down to the slide 2a, the operation of the straight module 2c can drive the second pushing block 2b to transfer the stainless steel bar to the next process.
[0031] In order to provide some buffering for the second push block 2b to contact the stainless steel bar, the second push block 2b includes a base 2b-1 with variable spacing and a push head 2b-2. The base 2b-1 is provided with a horizontal sliding hole, the push head 2b-2 is connected to a horizontal sliding rod and inserted into the horizontal sliding hole, and an elastic compression spring is sleeved around the horizontal sliding rod. The lower end of the push head 2b-2 is provided with a V-shaped protrusion that is embedded in the sliding groove 2a.
[0032] In addition, the baffle near the second pusher module 2 has a notch and an arc-shaped baffle 10 is installed. The arc-shaped baffle 10 narrows a section of the channel between the two baffles, so that the stainless steel bar moves along the same path on the horizontal conveyor belt.
[0033] In operation, the stainless steel bar feeding device first feeds the stainless steel bars onto the horizontal conveyor belt of the conveyor belt module 1 via the feeding ramp 7. The baffles on both sides of the horizontal conveyor belt prevent the bars from falling. The notch on the baffle near the second pushing module 2 aligns with the feeding ramp 7, facilitating the entry of the bars. Simultaneously, the arc-shaped baffle 10 installed on this baffle narrows the passage between the two baffles, guiding the bars to move more uniformly towards subsequent stages.
[0034] When the stainless steel bar is conveyed from the side of the laser rangefinder 6 to the side of the contact sensor 5 along the horizontal conveyor belt, the contact sensor 5 will send a signal to the control system after it comes into contact with the front end of the bar. At this time, the laser rangefinder 6 starts to work, measuring the distance between itself and the rear end of the bar. The processor in the control system calculates and then determines the length of the bar.
[0035] When the measured length of the stainless steel bar meets the requirements, the top surface of the lifting sliding door 4a is flush with the top surface of the transition ramp 4. Then, the telescopic cylinder of the first pushing module 3 extends, driving the first pushing block to push the bar from the horizontal conveyor belt to the transition ramp. Since the top of the transition ramp connects to the upper conveying surface of the horizontal conveyor belt, and the bottom connects to the top of one side of the chute 2a in the second pushing module 2, and the height of the second pushing module 2 is lower than the height of the conveyor belt module 1, the bar will slide along the transition ramp 4 into the chute 2a. The chute 2a is V-shaped and open upwards, which can effectively transport the bar. Afterwards, the linear module 2c drives the second pushing block 2b to move in the chute 2a, pushing the bar to the subsequent processing equipment. The elastic mechanism in the second pushing block provides a buffering effect during the pushing process, and the V-shaped protrusion at the lower end of the push head 2b-2 is embedded in the chute to ensure the stability of the pushing process.
[0036] If the measured length of the bar does not meet the qualification standard, the lifting power device 8 drives the lifting movable door 4a to descend, exposing the through-hole of the transition slope 4. After the first pushing module 3 pushes the bar towards the transition slope 4, the bar will fall from the through-hole and enter the material box 9 below, thus realizing the screening of unqualified bars.
[0037] Through the above structure and working process, this utility model realizes the measurement and screening of the length of stainless steel bars during the feeding process, effectively improving processing efficiency and product quality.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. It should be noted that for those skilled in the art, any changes, modifications or additions made without departing from the concept of the present utility model should fall within the protection scope of the present utility model.
