Abstract

The utility model relates to a tube baking machine for processing an energy-saving glass tube. The utility model aims at providing a tube baking machine which has the advantages of reasonable design of structure, long time of effective blowing, lower energy consumption and higher output. The technical proposal is that: the tube baking machine is blowing intermittently. The tube baking machine comprises a plurality of blowing tubes which are fixed in an intracavity of an oven; a chain conveyor; a chain wheel group and a driving device which are cooperated with the chain conveyor. A plurality of blowing tubes are horizontally and hung and fixed on the lower part of the chain conveyor which are parallel to each other. Each blowing tube is provided with a plurality of blowing mouths. Each blowing mouth is opened upward. Tube hangers are evenly suffused on the chain conveyor. The tube hanger is used for hanging the energy-saving glass tube. The blowing tubes are communicated by a wind pipe which is communicated with a wind source; the wind pipe is inserted into the intracavity of the oven from the outside. The chain conveyer circularly moves and goes through the over from beginning to end. An intermittent wind-door switch is arranged on the wind pipe. The switch of the intermittent wind-door is a cam-typed throttle switch. The driving device is an electrical machine and a decelerating machine driven by the driving device.

Description

The tube-baking machine of blowing at intermittence

Technical field

The utility model relates to a kind of electric light source production equipment, specifically is the tube-baking machine of processing electricity-saving lamp glass tube.

Background technology

U bend energy lamp lens pipe in process of production need be through the technical process of a roasted tube.Be about to coat glass lamp behind the fluorescent material and send baking oven to and be heated to 480 ℃-520 ℃, be blown into air (oxygen) then, the auxiliary material (adhesive etc.) that adds when being coated with fluorescent material burns.

The existing structure of copying the pipe machine is: whole baking oven is from first to last passed through in chain-type conveyer belt continuously and smoothly motion, evenly fixing the fluorescent tube hanger of some suspension electricity-saving lamp glass tubes on the chain-type conveyer belt, all be positioned with a U bend energy lamp lens pipe on each fluorescent tube hanger, the mouth of pipe of these glass tubes moves with the conveyer belt continuously and smoothly down; Several blowers then laterally and in parallel to each other overhang and are fixed on the below of the chain-type conveyer belt that is positioned at oven ncavity, and the air outlet of blower all also continues blowing up, and extraneous wind regime is connected by the airduct and the blower of insertion oven interior; Air could be blown into the electricity-saving lamp glass tube by blower when the mouth of pipe of U bend energy lamp lens pipe moves to the air outlet of aiming at tracheae; Because the mouth of pipe of glass tube is aimed at the time of blower very short (be that effective blow-time is short, account for the sixth time), need bigger air quantity the gas displacement in the glass tube could be come out, and product quality is difficult for stable; And the most of the time (invalid blow-time accounted for for 5/6ths times) enters baking oven from the cold air that the air outlet of blower blows out, and has taken away a large amount of heats in the baking oven; Thereby the baking oven energy input that is disposed is higher.

The utility model content

The purpose of this utility model provides a kind of improvement of tube-baking machine, and this tube-baking machine should be able to overcome the deficiency of above-mentioned background technology, has reasonable in design, the characteristics that effectively blow-time is long, energy consumption reduces, output improves.

The technical solution adopted in the utility model is: the tube-baking machine of blowing at intermittence comprises some blowers, chain-type conveyer belt and the chain wheel set that cooperates with the chain-type conveyer belt that is fixed on oven ncavity, the power set that drive chain-type conveyer belt and sprocket wheel motion; Described several blowers laterally and in parallel to each other overhang and are fixed on the below of chain-type conveyer belt, and each blower is provided with several blowing mouths, and the equal opening of each blowing mouth up; Evenly be covered with the fluorescent tube hanger that is used to hang the electricity-saving lamp glass tube on the described chain-type conveyer belt, so that glass tube hangs the location and make the mouth of pipe of glass tube aim at the blowing mouth of blower down; Other has an airduct that is communicated with wind regime to connect described blower from outside insertion oven interior; Described chain-type conveyer belt shuttling movement runs through the head and the tail of baking oven; One batch (-type) air door switch is housed, so that off and on glass tube is blown on the described airduct.

Described batch (-type) air door switch is a cam-type roof pressure switch.

Described power set are reductors of motor and drive thereof.

Because the utility model adopted the batch (-type) air door switch, make blower air outlet with the mouth of pipe of glass tube to just drying on time, all the other times then stop blowing; Like this, the efficient of not only drying improves greatly, and needed air quantity reduces greatly, and product yield also is able to obvious raising; And owing to the invalid blowing amount that directly is blown into baking oven is eliminated substantially; The energy consumption of baking oven is able to remarkable reduction, can reduce 30%-40% generally speaking.

Embodiment

Intermittently the tube-baking machine of blowing comprises some blowers 3, chain-type conveying 4 and the chain wheel set that cooperates with chain that is fixed on baking oven 1 inner chamber, the power set (generally all being the reductor 6 of motor 7 and drive thereof) that drive chain-type conveyer belt and sprocket wheel 5 motions; Described chain-type conveyer belt enters from the inlet of baking oven 1, draw from the outlet of baking oven 1, and then run through the head and the tail (direction of motion is shown in the arrow A) of the whole baking oven that moves, evenly be covered with the fluorescent tube hanger 10 that is used to hang electricity-saving lamp glass tube 2 on the chain-type conveyer belt, so that the mouth of pipe that glass tube hangs the location and makes glass tube down; Described several blowers 3 laterally and in parallel to each other overhang and are fixed on the below of chain-type conveyer belt, each blower is provided with the blowing mouth 3-1 (as shown in Figure 3) identical with glass tube quantity, and the equal opening of each blowing mouth is up so that aim at the mouth of pipe of a glass tube; Other has an airduct 9 that is communicated with wind regime (wind regime is omitted among the figure) to connect described blower 3 from outside insertion oven interior.Above structure is the conventional set-up mode of existing tube-baking machine.

For improving result of use, the utility model is equipped with a batch (-type) air door switch on described airduct, so that the batch (-type) air feed.Described batch (-type) air door switch is a cam-type roof pressure switch.Among Fig. 2 as can be known: air door cam 14 rotates, and the swing by lever 13 moves up and down litter 12, can regularly open or close air door 8 (air door buyable), to reach the purpose of batch (-type) blowing.

Need to prove: air door cam 14 can directly be driven by speed reducer output shaft, to guarantee the accurate of blow-time, promptly just open the air door blowing when the mouth of pipe of glass tube moves to the blowing mouth of aiming at blower, air door is then closed when the blowing mouth of blower is removed in the mouth of pipe motion of glass tube.Like this, the efficient of not only drying improves greatly, and invalid blowing phenomenon eliminates substantially, has significantly reduced energy consumption.

In addition, the blower of airduct 9 connections has four (also can design six, quantity is determined as required) as we know from the figure; There are several blowing mouths (to show 16 among the figure on each blower; Quantity also can be determined as required), so there are 64 electricity-saving lamp glass tubes to dry simultaneously at every turn.And each electricity-saving lamp glass tube adds man-hour can be by four times (number of times be also decided as required) of blowing.
