Abstract
Description
Technical Field
[0001] This utility model relates to the field of glove manufacturing technology, and in particular to an anti-arc glove manufacturing equipment. Background Technology
[0002] Arc flash gloves are protective gloves specifically designed to protect workers from electric arcs and heat, and are primarily used in the power industry.
[0003] The specific production process of anti-arc gloves is as follows: First, the glove core is woven using appropriate materials. Then, anti-arc powder and anti-arc powder solvent are selected and mixed in a certain proportion to prepare an anti-arc slurry. Next, the anti-arc slurry is mixed evenly with modified nitrile latex in an immersion tank to obtain an anti-arc nitrile latex. Then, the glove core is placed on a hand mold and immersed in the anti-arc nitrile latex in the immersion tank. Next, the glove core with the anti-arc nitrile latex on its surface is moved to a drying area for drying treatment. Finally, the finished gloves are removed from the hand mold and stored in the warehouse.
[0004] Currently, in existing arc flash glove production equipment, when the hand mold with the glove core is immersed in arc flash nitrile rubber latex, the arc flash nitrile rubber latex is prone to coagulation due to environmental temperature differences, such as excessively high or low temperatures. The coagulated arc flash nitrile rubber latex does not easily adhere to the surface of the glove core, reducing the arc flash protection quality of the finished glove and significantly reducing the anti-coagulation properties of the arc flash nitrile rubber latex in the immersion tank of the arc flash glove production equipment. Consequently, the coagulated arc flash nitrile rubber latex cannot effectively adhere to the pre-set glove core surface on the hand mold. Utility Model Content
[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing an anti-arc glove production equipment.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design an anti-arc glove production equipment, including an immersion tank, a production base plate at the lower end of the immersion tank, a temperature controller and a probe on the immersion tank, a vertical cylinder on the production base plate, a top cover plate on the vertical cylinder, a connecting rod and a sealing groove on the top cover plate, a hand mold on the connecting rod, a drain pipe on the immersion tank, an installation groove on the top cover plate, a mixed flow motor in the installation groove, a main shaft on the mixed flow motor, a stirring blade on the main shaft, and a mixing port on the stirring blade;
[0008] The immersion tank has an embedded cavity, in which a heating wire and a heat-conducting baffle are installed;
[0009] The immersion tank is provided with a first heat insulation layer, and the top cover is provided with a second heat insulation layer.
[0010] Furthermore, the mounting groove is opened at the top of the top cover plate, the heat-conducting baffle is embedded in the inner cavity and is flush with the inner wall of the immersion tank, and the heating wire is disposed between the heat-conducting baffle and the inner cavity.
[0011] Furthermore, the hand mold and the connecting rod are arranged as a group, and there are four groups arranged horizontally in total. The hand mold does not come into contact with the stirring plate.
[0012] Furthermore, the outer wall of the immersion tank is provided with a sealing frame, which is a rectangular frame structure in general.
[0013] Furthermore, the main shaft and the mixed-flow motor are a set, and there are two sets arranged symmetrically front and rear.
[0014] Furthermore, the stirring blade is a trapezoidal structure with six blades arranged in a circle, and the mixing port is a long strip-shaped opening that extends through the stirring blade.
[0015] Furthermore, the first heat insulation layer is uniformly coated along the outer wall of the immersion tank, and the second heat insulation layer is uniformly coated along the outer wall of the top cover plate.
[0016] The arc-resistant glove production equipment proposed in this utility model has the following advantages:
[0017] 1. This utility model, by setting a temperature control and monitoring heating structure and a sealing frame on the immersion tank, and setting a vertical cylinder with a top cover plate on the production base plate, and then symmetrically setting a mixing and stirring structure and a pressure sealing groove on the top cover plate, achieves a complete compression and sealing of the top opening of the immersion tank. Then, the preset anti-arc nitrile rubber latex is symmetrically mixed, heated, stirred, and temperature monitored, which improves the anti-arc nitrile rubber latex in the immersion tank of the anti-arc glove production device, thereby ensuring that the anti-arc nitrile rubber latex adheres to the surface of the preset glove core on the hand mold.
[0018] 2. This utility model provides a first heat insulation layer on the outer wall of the immersion tank and a second heat insulation layer on the outer wall of the top cover. When the top cover is squeezed and sealed to the immersion tank and stirred and heated, the top cover and the immersion tank as a whole can achieve the effect of heat insulation between the top cover and the external environment, which greatly reduces the heat loss of the arc-resistant nitrile rubber latex in the immersion tank.

Detailed Implementation
[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] Reference Figure 1-6 An anti-arc glove production equipment includes an immersion tank 1, a production base plate 3 at the lower end of the immersion tank 1, a temperature controller 2 and a probe 21 on the immersion tank 1, a vertical cylinder 31 on the production base plate 3, a top cover plate 32 on the vertical cylinder 31, a connecting rod 6 and a sealing groove 33 on the top cover plate 32, a hand mold 61 on the connecting rod 6, a drain pipe 11 on the immersion tank 1, an installation groove 4 on the top cover plate 32, a mixed flow motor 41 in the installation groove 4, a main shaft 5 on the mixed flow motor 41, a stirring blade 51 on the main shaft 5, and a mixing port 52 on the stirring blade 51.
[0028] An embedded cavity 7 is provided on the immersion tank 1, and a heating wire 71 and a heat-conducting baffle 72 are provided in the embedded cavity 7;
[0029] The immersion tank 1 is provided with a first heat insulation layer 10, and the top cover plate 32 is provided with a second heat insulation layer 30. Some of the structures described in this patent are common structures in anti-arc glove production equipment and are existing technologies. Some existing structures are not drawn or marked and need not be described in detail.
[0030] The temperature controller 2 and the probe 21 are a set. The temperature controller 2 has a built-in PLC, and the probe 21 is a temperature probe. Both are existing technologies.
[0031] The mounting groove 4 is located at the top of the top cover plate 32. The heat-conducting baffle 72 is embedded in the inner cavity 7 and is flush with the inner wall of the immersion tank 1. The heat-conducting baffle 72 is made of red copper and has high thermal conductivity.
[0032] The heating wire 71 is disposed between the heat-conducting baffle 72 and the embedded cavity 7, and the heating wire 71 is a dry-burning type heating wire.
[0033] The hand mold 61 and the connecting rod 6 are a group, and there are four groups arranged horizontally in total. The glove core can be stably snapped onto the hand mold 61 and will not fall off. All of these are existing technologies.
[0034] The hand mold 61 does not come into contact with the stirring plate 51 to avoid collision with the stirring plate 51.
[0035] The outer wall of the immersion tank 1 is provided with a sealing frame 12. The sealing frame 12 is a rectangular frame structure and is made of EPDM ethylene propylene diene monomer rubber, which has excellent high elasticity, sealing and waterproof properties.
[0036] The main shaft 5 and the mixed-flow motor 41 are arranged as a group, and there are two groups in total, symmetrically set in front and behind, to achieve a symmetrical, uniform, and comprehensive stirring effect on the anti-arc nitrile rubber latex.
[0037] The stirring blade 51 has a trapezoidal structure and consists of six circumferentially arranged blades. The mixing port 52 has a long strip-shaped opening structure and passes through the stirring blade 51. When the stirring blade 51 rotates at a constant speed, the liquid gel-like anti-arc nitrile latex will pass through each mixing port 52 and form multiple liquid streams, which improves the effective contact with heat.
[0038] The first heat insulation layer 10 is uniformly coated along the outer wall of the immersion tank 1, and the second heat insulation layer 30 is uniformly coated along the outer wall of the top cover plate 32. Both the first heat insulation layer 10 and the second heat insulation layer 30 are silicate coatings, which have excellent heat insulation and are durable.
[0039] Working method: First, preset the temperature value on the preset PLC of the temperature controller 2 and start it (this temperature value can ensure the liquid gel state of the anti-arc nitrile rubber latex, which is the existing technology). Then, inject a certain amount of liquid gel state anti-arc nitrile rubber latex with temperature into the immersion tank 1. Then, securely attach the four glove cores to the hand mold 61. Next, start the vertical cylinder 31, which drives the top cover plate 32, connecting rod 6, and main shaft 5 to move downward as a whole. When the top cover plate 32 covers the immersion tank 1, the pressure sealing groove 33 will squeeze and seal with the sealing side frame 12. Then, start the mixing motor 41. The mixing motors 41 on both sides drive the stirring blades 51 to rotate at a uniform speed. Combined with the mixing port 52, the anti-arc nitrile rubber latex in the immersion tank 1 can be irrigated. The nitrile rubber latex undergoes symmetrical and comprehensive mixing. Simultaneously, probe 21 monitors the temperature of the arc-resistant nitrile rubber latex in real time and transmits the monitoring signal to the preset PLC in the temperature controller 2. If the monitored temperature value is lower than the preset temperature value on the PLC, the preset PLC will control the activation of heating wire 71. The heat generated by heating wire 71 is quickly transferred to the arc-resistant nitrile rubber latex through heat-conducting baffle 72. Combined with the mixing effect, heat transfer is achieved, ensuring that the arc-resistant nitrile rubber latex remains in a liquid gel state. Then, the arc-resistant nitrile rubber latex will evenly adhere to the surface of the preset glove core on the hand mold 61, thereby improving the anti-coagulation properties of the arc-resistant nitrile rubber latex in the immersion tank 1 of the arc-resistant glove production device.
[0040] In addition, by setting a first heat insulation layer 10 structure on the outer wall of the immersion tank 1 and a second heat insulation layer 30 structure on the outer wall of the top cover plate 32, when the top cover plate 32 is squeezed and sealed to the immersion tank 1 and stirred and heated, the top cover plate 32 and the immersion tank 1 as a whole can achieve the effect of heat insulation between the external environment and the external environment, which greatly reduces the heat dissipation of the anti-arc nitrile rubber latex itself in the preset immersion tank 1.
[0041] 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. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
