Description

Technical Field

[0001] This utility model belongs to the technical field of thermoplastic devices, and specifically relates to a thermoplastic device for cylindrical alkaline batteries. Background Technology

[0002] Cylindrical alkaline batteries are one of the most common types of dry cell batteries. Their electrolyte is alkaline potassium hydroxide, hence the name alkaline battery. Compared to older carbon-zinc batteries, they have more power, longer battery life, stable voltage during discharge, and longer storage time. They are widely used in small household appliances such as remote controls, toys, and flashlights. Modern alkaline batteries are mercury-free and more environmentally friendly. During the production process, cylindrical alkaline batteries usually require thermoplastic sealing of their outer packaging.

[0003] Traditional thermoplastic methods often employ static heating, where the battery is placed in a fixed position and heated on one side or in a localized area using a hot air gun or heating mold. Because the battery is cylindrical, uneven heating at the sealing point is very likely to occur, affecting the neatness and aesthetics of the battery packaging seal. To solve the above problems, we provide a thermoplastic device for cylindrical alkaline batteries. Utility Model Content

[0004] The purpose of this invention is to provide a thermoplastic device for cylindrical alkaline batteries, in order to solve the problem mentioned in the background art that traditional thermoplastic methods mostly use static heating, that is, the battery is placed in a fixed position and heated on one side or locally by a hot air gun or heating mold. Since the battery is cylindrical, it is very easy to cause uneven heating at the sealing point.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cylindrical thermoplastic device for alkaline batteries, comprising a cross frame, two gear shafts rotatably connected inside the cross frame, a transmission belt drivingly connected to the surface of the gear shafts, a rotating roller rotatably sleeved on the surface of the transmission belt, a first motor bolted to the front of the cross frame, the output end of the first motor being bolted to the gear shafts via a first coupling, a fixed plate fixedly connected to the front of the cross frame, two pulleys rotatably connected inside the fixed plate, a belt drivingly connected to the surface of the two pulleys, the outer side of the belt abutting against the rotating roller, a second motor fixedly connected to the front of the fixed plate, the output end of the second motor being bolted to the pulleys via a second coupling, and a heating mechanism provided at the top of the cross frame.

[0006] Preferably, the heating mechanism includes a housing, the bottom of which is fixedly connected to a crossbeam, a heating plate is fixedly connected inside the housing, and a fan is fixedly connected inside the housing.

[0007] Preferably, one end of the crossbar is provided with a sliding groove, and a slider is slidably connected inside the sliding groove. The slider is rotatably connected to the gear shaft, and an adjusting bolt is threaded inside the crossbar.

[0008] Preferably, one end of the adjusting bolt abuts against the slider, and one end of the crossbar is fixedly connected to an end plate.

[0009] Preferably, support legs are fixedly connected to both sides of the bottom of the cross frame, and a reinforcing rod is provided at the bottom of the cross frame, with both ends of the reinforcing rod fixedly connected to the support legs respectively.

[0010] This utility model has the following beneficial effects: This device automatically and smoothly feeds cylindrical batteries into the thermoforming station via a conveyor belt driven by a first motor. A hot air device consisting of a fan and a heating plate is installed above the conveyor belt. After the battery enters the casing, a second motor drives a rotating roller through a pulley and belt, thereby causing the cylindrical battery to rotate actively. This ensures that all parts of the battery packaging are heated evenly, effectively avoiding the uneven thermoforming caused by localized overheating that may occur with traditional static heating methods. It significantly improves the uniformity of the thermoforming seal of the battery packaging and the product quality, demonstrating good practicality and reliability. Attached Figure Description

[0020] Brief description of the usage process: The user starts the first motor 5, which drives the transmission belt 3 to rotate through the gear shaft 2, so that the transmission belt 3 can transport the cylindrical battery. Hot air is blown by the fan 103 and the heating plate 102. When the transmission belt 3 transports the cylindrical battery into the inside of the casing 101, the second motor 9 is started, which drives the belt 8 to rotate through the pulley 7, so that the belt 8 drives the rotating roller 4 to rotate. The rotating roller 4 drives the cylindrical battery to rotate, so that the outer packaging of the cylindrical battery can be uniformly thermoformed, and the sealing thermoformation is uniform.
