Description

Technical Field

[0001] The utility model relates to the technical field of machining, and particularly relates to a strip butt joint conveying device. Background Art

[0002] The metal strip forming process is widely used in fields such as automobile manufacturing, construction, and shipbuilding. The strip is roll-formed in a certain order to obtain a specific cross-section. Through this process, high-quality section steel products can be produced. Since most strips are in the form of coils, in the actual production process, when the strip on the coil is used up, a new coil needs to be replaced, and the head of the new coil needs to be butt-welded to the tail of the old coil to maintain continuous feeding. In actual production, the butt joint welding of the strip is mainly carried out manually or by using a semi-automatic butt joint method. Manual butt joint requires at least two operators, one pulling the head of the strip and the other pulling the tail of the strip, which not only increases the labor cost and labor intensity but also affects the production efficiency of the whole line. The semi-automatic butt joint usually has the problem that the head and tail of the strip are not aligned, directly affecting the welding quality and efficiency, and further affecting the subsequent feeding accuracy and production quality.

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] like Figures 1 - 3 As shown, the utility model includes a frame 1, and vertical plates are arranged on both sides of the frame 1. The vertical plates are provided with an upper bearing seat 3 and a lower bearing seat 4. The upper bearing seat 3 and the lower bearing seat 4 are both 2 in number. Both ends of the upper feed roller 5 and the lower feed roller 6 are respectively installed in the upper bearing seat 3 and the lower bearing seat 4. The upper bearing seat 3 and the vertical plates are connected by a sliding pair. The upper bearing seat 3 is driven by a driving assembly 13 and can slide up and down along the vertical plates to achieve compression of the material belt 7. The lower feed roller 6 is driven by a motor 11.

[0021] A material guide assembly is provided at the feeding end of the frame 1, and the material guide assembly is composed of an arc plate 8, a first roller 8-1, and a second roller 8-2; there are two arc plates 8, which are symmetrically arranged on both sides of the frame 1, and both ends of the first roller 8-1 and the second roller 8-2 are respectively installed on the arc plate 8, and the material belt 7 is in rolling contact with the first roller 8-1 and the second roller 8-2; the first guide assembly and the second guide assembly are respectively provided at the feeding end and the discharging end of the frame 1 to guide the material belt 7. The function of the first roller 8-1 and the second roller 8-2 is to play an auxiliary supporting role for the material belt 7 when the thickness of the material belt 7 is thin or the remaining tail is short.

[0022] The above-mentioned feeding and discharging, such as Figures 1 - 2 As shown, it is just the overall feeding and discharging of the assembly line processing in the normal production process. In fact, when the material belt is docked, in order to facilitate docking, the forward and reverse rotation of the motor 11 may be used to realize the feeding and retraction of the material belt, so as to facilitate docking with the new material belt.

[0023] When the strip 7 is butt - jointed, there are sometimes situations where alignment cannot be achieved. Therefore, the frame needs to be adjusted. The following design can be adopted: An adjusting seat 2 is added below the frame 1. A first slide rail 2 - 1 is provided on the adjusting seat 2, and a first slider matching the first slide rail 2 - 1 is provided below the frame 1. The frame 1 can slide and adjust its position on the adjusting seat 2, and after adjusting the position, it can be locked by a locking bolt 2 - 2.

[0024] The sliding pair between the upper bearing seat 3 and the vertical plate can be designed as follows: Second slide rails 1 - 1 are provided on the vertical plates on both sides of the frame 1, and second sliders 3 - 1 matching the second slide rails 1 - 1 are provided on the upper bearing seat 3; The driving component 13 can be a hydraulic cylinder or a pneumatic cylinder, and the head of the piston rod of the driving component 13 is connected to the upper bearing seat 3.

[0025] The first guiding component at the feeding end can be designed as follows: The first guiding component is composed of a clamping bracket 9 and a first guiding cylinder 9 - 1 and a second guiding cylinder 9 - 2 arranged thereon; A first sliding groove is provided on the clamping bracket 9. The first guiding cylinder 9 - 1 is arranged vertically and can rotate around its central axis. A guiding slide rod and a locking nut 9 - 3 matching the first sliding groove are provided below the central axis; The second guiding cylinder 9 - 2 has the same structure and setting method as the first guiding cylinder 9 - 1. The above structure realizes that the first guiding cylinder 9 - 1 and the second guiding cylinder 9 - 2 are movably fixed on the first sliding groove of the clamping bracket 9; The first guiding cylinder 9 - 1 and the second guiding cylinder 9 - 2 can rotate, and their contact with the strip is a rolling contact. Even if there is no rotation function, since the contact surface between the strip and the two guiding cylinders is extremely small, the friction can be ignored.

[0026] The guiding slide rod can drive the first guiding cylinder 9 - 1 to slide in the first sliding groove, thereby adjusting the distance between the first guiding cylinder 9 - 1 and the second guiding cylinder 9 - 2, so as to adapt to the guiding of strips 7 with different widths. The lower part of the guiding slide rod is provided with threads, and the locking nut 9 - 3 matches the threads at the lower part of the guiding slide rod, which can realize the locking of the guiding slide rod in the first sliding groove. A gasket can be provided between the locking nut 9 - 3 and the clamping bracket 9. The cross - section of the guiding slide rod in the first guiding groove can be designed as a rectangle or a circle, and a rectangle is more conducive to the stability of the first guiding cylinder and the second guiding cylinder. The above is one way of locking. There are many conventional techniques for locking the slide rod or slider on the sliding groove, which will not be elaborated here.

[0027] The second guiding component at the discharging end is similar in structure to the first guiding component. The difference is to prevent the tape from warping, and the following design can be adopted: The second guiding component is composed of a guiding frame 10 and a third guiding cylinder 10-1 and a fourth guiding cylinder 10-2 arranged thereon; a second sliding groove is provided on the guiding frame 10, and the third guiding cylinder 10-1 and the fourth guiding cylinder 10-2 are arranged on the second sliding groove in the same way as the first guiding cylinder 9-1 is arranged on the first sliding groove; a material blocking ring is arranged at the upper ends of the third guiding cylinder 10-1 and the fourth guiding cylinder 10-2, and the material blocking ring can prevent the tape 7 from warping upward. In the above design, the third guiding cylinder 10-1 and the fourth guiding cylinder 10-2 are arranged vertically, realizing their movable fixation on the second sliding groove of the guiding frame 10, thereby realizing the adjustment of the distance between the two to adapt to the width of the tape.

[0028] Before the tape conveying ends, the tape needs to be butt-jointed. The following monitoring mechanism can be designed: A laser distance sensor 12 is arranged on the adjusting seat 2, and a CPU and a control circuit are added. The signal output of the laser distance sensor 12 is connected to the input end of the CPU, and the output end of the CPU is connected to control the start and stop of the motor 11. The output of the CPU can be connected to control the relay through a triode amplification circuit, thereby controlling the start and stop of the motor 11. The output of the CPU is connected to the base of the triode amplification circuit, the collector of the triode amplification circuit is connected to control the relay, and the CPU can select a C8051F340 series chip; the laser distance sensor 12 can select ifm O1D105 or other brand series. Its accuracy requirement is not high, only to detect whether there is a tape on the rack. The laser distance sensor 12 can also be replaced by an inductive proximity switch or an ultrasonic distance sensor.
