Description

 The invention relates to equipment for moving bodies of revolution in the installation for coating and can be used in the installation for spraying coatings on textile cartridges.

 The closest known one is a conveyor for moving rotation bodies in a coating installation, including a chain connected to a pneumatic actuator, comprising sprockets and supporting cartridge holders, each of which is made in the form of an axis and a mandrel.

 A disadvantage of the known conveyor is the frequency of rotation, affecting the quality of the applied coating, reducing its uniformity.

 The aim of the invention is the transfer of ammunition constant rotational motion.

 The goal is achieved in that the conveyor for moving the bodies of rotation in the installation for coating, including a chain connected to the pneumatic drive, covering the sprockets and supporting the cartridge holders, each of which is made in the form of an axis and a mandrel connected to the chain, according to the invention, is equipped with a mechanism for the constant rotation of the cartridge holder mandrels made in the form of an electric drive with a drive sprocket mounted on its shaft and mounted on the mandrels of the cartridge holders of driven sprockets with a chain covering them for interaction action with the drive sprocket of the drive shaft, with each mandrel made in the form of a tube freely mounted on the corresponding axis.

 In FIG. 1 shows a kinematic diagram of a conveyor in a coating apparatus; in FIG. 2, section AA in FIG. one.

 In FIG. 1 shows a coating installation with a conveyor. It includes a hopper 1 with cartridges 2, a feeder with a pusher 3, operating from a pneumatic actuator (not shown), a guide pipe 4, including a bath 5, a receiver 6 and a pusher 7.

 The conveyor serves to move the cartridges in the installation for coating. The cartridges are moved on the cartridge holders 8, each of which is made in the form of a mandrel (Fig. 2), consisting of a tube 9, freely mounted on the axis 10. The axis 10 is rigidly mounted on two parallel chains 11, tensioned on two pairs of sprockets 12, mounted on shafts 13.

 One of the shafts 13 is connected to the pneumatic actuator 14 by a pair of rack-pinion gear 15. Parallel to the cartridge holder 8, at the beginning of the coating cycle, there is a pneumatic holder 16, and at the end of the same cycle there is a cartridge pusher 17.

 Each tube 9 of the mandrel holder 8 is equipped with a driven sprocket 18 (Fig. 1, 2), on which a chain 19 (Fig. 1) is worn, which is engaged with the drive sprocket 20, mounted on the shaft of the electric drive 21.

 The electric drive 21 with the drive sprocket 20 fixed on its shaft and the driven sprockets 18 mounted on the mandrel holder mandrels 8 with a chain 19 covering them for interaction with the drive sprocket 20 of the electric drive 21 constitute a mechanism for the constant rotation of the mandrel holder mandrels 8.

 The diagram also shows a fan 22 with a heater 23 connected to it, which performs drying and preheating of the cartridges 2 with a coating on them.

 Installation together with the conveyor operates as follows.

 Turn on the feeder. The pusher 3 from the hopper 1 pushes the cartridge 2 into the degreasing bath 5, in which the degreasing solution is located. Fat-free cartridge 2 under the action of the pusher 3 is pushed into the receiver 6 and using the pusher 7 is mounted on the cartridge holder 8.

 A pneumatic atomizer 16, operating from a pneumatic actuator (not shown) and tuned to a predetermined speed, applies a coating on the cartridge 2, mounted on the cartridge holder 8. In order for the coating layer to be applied uniformly along the length and diameter of the cartridge, all cartridge holders are constantly rotated from the electric drive 21 by means of a chain 19, worn on driven sprockets 18 and meshed with a drive sprocket 20, mounted on the shaft of the electric drive 21.

 Then, the coated cartridge 2 on the cartridge holder 8 is supplied by chains 11 stretched on sprockets 12 strung on the shafts 13 into the drying and heating zone to the fan 22 with an air heater 23.

 The dried and heated cartridge, ready for the subsequent heat treatment operation, enters the pusher 17, which pushes it onto the conveyor (not shown), and the pusher 7 pushes a new skimmed cartridge onto the cartridge holder 8. The cartridge spraying cycle is repeated.

Claims (1)
