Abstract
Description
Technical Field
[0001] This utility model relates to the field of automatic refueling structure technology, specifically an automatic refueling structure for a battery laminator. Background Technology
[0002] Currently, battery laminators require regular lubrication and oil replenishment of transmission components and working chambers during operation to ensure stable operation under high temperature, high pressure, and continuous working conditions. Existing oil replenishment methods mainly rely on traditional oil pump structures or solenoid valve-controlled oil supply mechanisms.
[0003] Traditional oil pump filling structures often employ gear pumps, piston pumps, or a single drive motor paired with a linear pump body, using rotation or reciprocating motion to deliver oil. While these structures can provide a certain flow rate, they typically require additional control valve assemblies to switch between suction and discharge, resulting in a complex system construction. Furthermore, since the pump body is mostly a fixed, integral structure, wear on a seal or internal plunger often necessitates complete replacement or system shutdown for maintenance, leading to high maintenance costs.
[0004] Another common oil supply method utilizes a combination of a solenoid valve and an oil pump, with the solenoid valve switching between the inlet and outlet channels. This structure enables basic automation, but the solenoid valve is prone to slow response, poor sealing, or jamming under long-term high-frequency operation, leading to discontinuous oil supply or even localized oil shortages, affecting the stable operation of the laminator. Furthermore, the solenoid valve and oil pump are often installed separately, occupying a large space, with complex piping connections, and a higher risk of leakage.
[0005] Therefore, there is an urgent need to propose a new automatic refueling structure to simplify the overall mechanism, realize the linkage between driving, oil suction and oil pressure, ensure the stability and continuity of oil circulation, and improve sealing and wear resistance, thereby improving the service life and operational reliability of the battery laminator. Utility Model Content
[0006] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0007] Therefore, the technical solution adopted by this utility model is as follows: an automatic refueling structure for a battery laminator, including a refueling box, a transmission assembly, and a piston block. The refueling box has an oil storage tank on its inner side, and a drive motor is fixedly installed on its surface. The transmission assembly includes a shaft disc and a plunger rod. The drive motor drives the shaft disc to rotate inside the refueling box. An eccentric pin is provided on the surface of the shaft disc, and the bottom end of the plunger rod is rotatably sleeved on the surface of the eccentric pin. A pump cylinder is provided inside the piston block, and the plunger rod is slidably sleeved inside the pump cylinder. An oil inlet chamber and an oil outlet chamber are provided inside the refueling box, and an oil suction pipe and an output cap are detachably installed at the ends of the oil inlet chamber and the oil outlet chamber, respectively. During operation, the piston cylinder alternately connects with the oil inlet chamber and the oil outlet chamber through the swing of the piston block, realizing the cyclic switching of oil between suction and pressure delivery, thus ensuring the continuity and automation of the refueling process.
[0008] In a preferred embodiment, one end of the oil suction pipe extends to the bottom surface of the inner cavity of the oil storage tank, for guiding the oil inside the oil storage tank into the inner side of the oil tank, and the output cap is used to communicate with the laminator's filler nozzle. Specifically, this structural design ensures that the oil in the oil storage tank is fully utilized and that the oil is efficiently transported to the working components of the laminator.
[0009] In a preferred embodiment, the piston block is further configured as follows: the piston block has a cylindrical structure, and a circular cavity is provided on the inner side of the refueling tank for the rotation of the transmission component and the piston block. Specifically, the cylindrical design and the cooperation of the circular cavity make the movement of the transmission component and the piston block more stable, improving the reliability and durability of the overall structure.
[0010] In a preferred embodiment, the oil inlet and outlet chambers are further configured such that they are symmetrically arranged about the centerline of the piston block, and are used to alternately connect with the pump cylinder port during the reciprocating deflection of the piston block. Specifically, the symmetrical arrangement enables the pump cylinder to smoothly switch between the oil inlet and outlet channels under the drive of the piston block, thereby improving the balance and continuity of oil delivery.
[0011] In a preferred embodiment, the plunger rod is further configured such that a piston ring is provided on its surface, and the outer circumference of the piston ring slides against the inner side of the pump cylinder. Specifically, the piston ring seal improves the sealing performance of the plunger rod during reciprocating motion, prevents oil leakage, and enhances the efficiency of oil intake and delivery.
[0012] In a preferred embodiment, the eccentric pin is further configured as follows: the eccentric pin has a cylindrical pin structure, and the axis of the eccentric pin is offset from the axis of the shaft disc and the output end of the drive motor. Specifically, through the eccentric transmission design, the plunger rod can generate stable reciprocating motion within the pump cylinder, ensuring continuous and reliable oil supply.
[0013] In a preferred embodiment, the plunger rod is further configured such that: a collar is provided at the end of the plunger rod, and a bearing is provided on the inner side of the collar, which is fitted onto the surface of the eccentric pin; the outer periphery of the plunger block and the inner wall of the circular cavity inside the fuel dispenser box are both hardened. Specifically, the bearing support reduces friction of the plunger rod during reciprocating motion, improving transmission efficiency. Simultaneously, the hardening treatment enhances the wear resistance of the plunger block and the inner wall of the fuel dispenser box, extending the service life of the overall structure.
[0014] The beneficial effects achieved by this utility model are as follows:
[0015] 1. In this utility model, through the linkage of the drive motor, shaft disc and eccentric pin, the plunger rod generates a stable radial reciprocating motion inside the pump cylinder, thereby driving the plunger block to swing back and forth, realizing the alternating connection between the pump cylinder and the oil inlet chamber and the oil outlet chamber, forming an oil suction and oil pressure cycle, which specifically improves the automation and stability of the oil supply process and ensures the continuous oiling needs of the battery laminator during operation.
[0016] 2. In this utility model, the oil suction pipe extends deep into the bottom of the oil storage tank to ensure that the oil can be fully sucked in; the piston rod surface is provided with a piston ring and slides and seals with the inner side of the pump cylinder, and with the hardening treatment of the outer periphery of the piston block and the inner hole of the refueling box, the system maintains good sealing performance and wear resistance during long-term operation, which specifically improves the conveying efficiency.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.
[0026] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.
[0027] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing an automatic oiling structure for a battery laminator.
[0028] Combination Figures 1-4 As shown, the present invention provides an automatic refueling structure for a battery laminator, including a refueling machine box 100, a drive motor 110, an oil storage tank 120, an output end cap 130, an oil inlet tank 140, an oil outlet tank 150, an oil suction pipe 121, a transmission assembly 200, a shaft disc 210, an eccentric pin 211, a plunger rod 220, a plunger block 300, and a pump cylinder 310.
[0029] The refueling unit 100 is an integral box structure, with an internal oil storage tank 120 for storing oil. A drive motor 110 is fixedly mounted on the surface of the refueling unit 100, serving as a power source to provide continuous rotational driving force to the transmission assembly 200. The inner side of the refueling unit 100 also has an oil inlet tank 140 and an oil outlet tank 150. The oil inlet tank 140 is connected to the oil suction pipe 121, and the end of the oil outlet tank 150 is equipped with an output cap 130 for connecting to the refueling interface of the battery laminator, thereby achieving automatic oil output.
[0030] The transmission assembly 200 includes a shaft disk 210 and a plunger rod 220. The output end of the drive motor 110 is connected to the shaft disk 210, enabling the shaft disk 210 to rotate stably inside the refueling tank 100. An eccentric pin 211 is fixedly mounted on the surface of the shaft disk 210. The axis of the eccentric pin 211 is offset from the central axis of the shaft disk 210 and the central axis of the output end of the drive motor 110, thereby generating eccentric motion during rotation. The bottom end of the plunger rod 220 is mounted on the surface of the eccentric pin 211 by a rotatable sleeve, and achieves radial reciprocating motion as the eccentric pin 211 rotates.
[0031] A pump cylinder 310 is provided on the inner side of the plunger block 300, and the upper end of the plunger rod 220 is slidably sleeved on the inner side of the pump cylinder 310. As the plunger rod 220 reciprocates, the plunger block 300 swings back and forth around its installation position inside the refueling tank 100, thereby realizing the alternating communication between the pump cylinder 310 and the oil inlet tank 140 and the oil outlet tank 150 at different positions.
[0032] In a preferred embodiment, one end of the oil intake pipe 121 extends to the bottom inner wall of the oil storage tank 120, allowing the oil inside the oil storage tank 120 to be completely introduced into the oil tank 140, avoiding oil residue and ensuring sufficient oil supply. The output cap 130 is fixedly installed at the end of the oil discharge tank 150 for connection to the filler nozzle of the battery laminator, enabling direct oil output.
[0033] In a preferred embodiment, the piston block 300 has a cylindrical structure, and a circular cavity is provided on the inner side of the refueling tank 100 for the transmission assembly 200 and the piston block 300 to rotate together, so that the system operation is more stable.
[0034] In a preferred embodiment, the oil inlet chamber 140 and the oil outlet chamber 150 are symmetrically arranged about the centerline of the piston block 300. When the piston block 300 deflects to one side, the pump piston cylinder 310 communicates with the oil inlet chamber 140; when the piston block 300 deflects to the other side, the pump piston cylinder 310 communicates with the oil outlet chamber 150, realizing the alternating switching of oil between suction and pressure delivery, thereby completing continuous oil supply.
[0035] In a preferred embodiment, the surface of the plunger rod 220 is provided with a piston ring, the outer periphery of which slides against the inner side of the pump cylinder 310, so that the plunger rod 220 maintains good sealing during reciprocating motion, preventing oil leakage, and improving the efficiency of oil intake and delivery.
[0036] In a preferred embodiment, the eccentric pin 211 has a cylindrical pin structure, and its axis is offset from the axis of the shaft disk 210 and the output end of the drive motor 110, so that the plunger rod 220 can generate regular radial reciprocating motion inside the pump cylinder 310, thereby driving the plunger block 300 to deflect stably.
[0037] In a preferred embodiment, the end of the plunger rod 220 is provided with a collar, and a bearing that engages with the surface of the eccentric pin 211 is installed on the inner side of the collar, so that the plunger rod 220 can reduce friction and extend its service life during reciprocating motion. The outer periphery of the plunger block 300 and the inner wall of the circular cavity inside the refueling tank 100 are both hardened to improve wear resistance and ensure long-term reliable operation of the system.
[0038] Working principle and usage process of this utility model:
[0039] When the drive motor 110 starts, it drives the shaft disk 210 to rotate inside the fuel dispenser box 100. Since the eccentric pin 211 is located on the surface of the shaft disk 210 and its axis is offset from the rotation center of the drive motor 110's output end, as the shaft disk 210 rotates, the eccentric pin 211 generates eccentric motion, thereby driving the plunger rod 220 to reciprocate radially inside the pump cylinder 310. Under the action of this reciprocating motion, the piston block 300 simultaneously oscillates back and forth around its mounting position.
[0040] During the swinging process of the piston block 300, the pump cylinder 310 alternately connects with the oil inlet chamber 140 and the oil outlet chamber 150. When the pump cylinder 310 is connected to the oil inlet chamber 140, the piston rod 220 retracts inside the pump cylinder 310, causing a negative pressure to be formed inside the pump cylinder 310 and the oil inlet chamber 140. The oil suction pipe 121 draws the oil from the bottom of the oil storage tank 120 into the oil inlet chamber 140 and into the pump cylinder 310.
[0041] When the piston block 300 deflects to the other side and the pump cylinder 310 is connected to the oil discharge chamber 150, the upward movement of the piston rod 220 causes the oil in the pump cylinder 310 to be pumped to the oil discharge chamber 150, and then delivered to the laminator's oil filling nozzle through the output cap 130, thus realizing the automatic oil filling process.
[0042] In terms of operation, the operator only needs to connect the control end of the drive motor 110 to the control mechanism of the battery laminator. When oiling is required, the drive motor 110 is turned on, and the output cap 130 is connected to the oiling interface of the battery laminator to complete the automatic oiling process of the battery laminator. It has the advantages of compact structure, reliable operation, high conveying efficiency and convenient use.
