Description

Technical Field

[0002] Copper strip is a metal component. The product specifications include 0.1~3×50~250mm copper strip products in various states. It is mainly used to produce electrical components, lamp holders, battery caps, buttons, seals, connectors, and is mainly used as conductive, heat-conductive, and corrosion-resistant equipment. During production and processing, the copper strip needs to be cut according to the use requirements. Therefore, cutting equipment is needed. China has authorized a utility model patent (Announcement No.: CN218836264U) to disclose an equidistant cutting device for stripped copper strips. When in use, the copper strip is first placed on a reel, and then the reel is placed on the machine body. The first motor and the second motor are started to drive the rolling rod and the rolling rod to rotate respectively, and the copper strip is transmitted to the cutting bottom. The hydraulic rod can be extended and retracted to cut the stripped copper strips at equal distances, thereby improving work efficiency.

[0003] Although the above device can perform quantitative and equidistant cutting of the copper strip when in use, there are still some shortcomings during use: due to the material characteristics of the copper strip itself, especially when its thickness is thin, the copper strip is prone to warping after being transmitted to the cutting station. During the cutting process, the partially warped copper strip will cause uneven contact between the cutter and the copper strip, affecting the cutting quality. Therefore, a copper strip cutting machine with a quantitative function is proposed to address the above situation. Utility Model Content

[0008] A baffle is hinged on the machine body, a pair of limiting sleeves are arranged at the bottom of the baffle, and a pair of limiting columns are arranged on the top of the machine body near the discharge port, and the limiting columns cooperate with the limiting sleeves.

[0009] Preferably, the cutting assembly includes a bracket arranged on the top of the machine body, a cylinder is arranged on the top of the bracket, a movable end of the cylinder passes through the bracket and is fixedly connected to a knife holder, a cutting knife is arranged at the bottom of the knife holder, and a fixing plate is fixed on the knife holder.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-5 A copper strip cutting machine with quantitative function includes a machine body 1, the machine body 1 has a discharge port 101, a collecting box is placed on the ground near the discharge port 10, and a cutting component is arranged on the machine body 1.

[0025] In this embodiment, Figure 1 and Figure 3 As shown, the cutting assembly includes a bracket 2 arranged on the top of the body 1, a cylinder 201 is arranged on the top of the bracket 2, the movable end of the cylinder 201 passes through the bracket 2 and is fixedly connected to a knife holder 202, a cutter 203 is arranged at the bottom of the knife holder 202, and a fixed plate 301 is fixed on the knife holder 202. Furthermore, when working, the copper strip is conveyed to the bottom of the cutter 203, the cylinder 201 is turned on to make it work, and the piston rod of the cylinder 201 can be extended and retracted to cut the stripped copper strips in equal intervals and quantities, thereby improving work efficiency.

[0026] like Figure 1 As shown, a through hole is formed through the top of the bracket 2 , and the through hole cooperates with the moving end of the cylinder 201 .

[0029] During use, when the cutter 203 descends, the pressure roller 305 first contacts the copper strip to be cut. As the cutter 203 continues to descend, the connecting plate 303 rotates and is connected to the fixed plate 301, which causes the connecting plate 303 to rotate, thereby causing the pressure roller 305 to contact the copper strip and move to both sides, ensuring that the pressure roller 305 always positions the copper strip while the cutter 203 descends and cuts.

[0030] A baffle 4 is hinged on the machine body 1 , a pair of limiting sleeves 402 are arranged at the bottom of the baffle 4 , and a pair of limiting posts 401 are arranged at the top of the machine body 1 near the discharge port 101 , and the limiting posts 401 cooperate with the limiting sleeves 402 .

[0032] In this embodiment, Figure 1 and Figure 4 As shown, a pair of handles are provided on the baffle plate 4, and after the baffle plate 4 rotates, it and the discharge port 101 are combined to form a storage cavity.

[0033] During use, when the collection box for collecting the cut copper strips is full, the baffle 4 can be rotated and the limit sleeve 402 can be sleeved on the limit column 401, so that a storage cavity is formed between the baffle 4 and the discharge port 101 for temporary material storage, which is convenient for the staff to remove the collection box and replace it with a new one, avoiding the cut copper strips from falling to the ground, thereby providing convenience for the overall cutting operation.
