Description

Technical Field

[0001] The utility model relates to the technical field of transmission equipment, in particular to a chain transmission component of an 18-station turntable production line of high-elasticity polyurethane damping material. Background Art

[0002] Polyurethane foam elastic cushion is a microporous polyurethane elastomer with performance between elastomers and foam materials, density between foam and solid materials, pore size of 0.1-10μm, relatively uniform pore size distribution, good energy absorption and cushioning performance, and can be used as a vibration damping material in rail transit vibration damping pads and building vibration reduction projects; the 18-station turntable production line is an efficient and highly automated production equipment. In the production process of polyurethane foam elastic cushion, the 18-station turntable production line is required to cast high-elasticity polyurethane damping materials; the turntable production line is continuous (on the move), and 18 sets of pneumatic mold frames can be placed on the turntable to realize the production of polyurethane foam elastic cushion. It has a compact structure and is easy and safe to operate and maintain. The mold temperature controller for heating is placed between the mold frame stations, and the temperature control water and cables are connected with hoses.

[0003] The main drive of the 18-station turntable production line adopts chain drive, that is, the entire turntable production line is driven by a variable frequency reduction motor with a brake through a sprocket box. The sprocket box is the core component that drives the entire turntable production line, and its importance is self-evident. In order to ensure the smooth operation of the production line and extend the service life of the equipment, the maintenance of the sprocket assembly is particularly important. Among them, adding lubricating oil is an indispensable part of maintenance work, which can reduce the friction between the sprocket and the chain, reduce wear and improve transmission efficiency. However, in actual operation, most of the existing sprocket boxes adopt a closed structure, which undoubtedly brings great inconvenience to the addition of lubricating oil to the sprocket. Since the sprocket box is enclosed inside, it is difficult for the operator to directly contact the sprocket assembly, which in turn brings difficulties to the oil addition work. In view of this, we propose a chain drive assembly for the 18-station turntable production line with high elasticity polyurethane damping material. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] This embodiment provides a technical solution:

[0029] See also Figure 1-Figure 4 As shown, the chain transmission assembly of the high-elastic polyurethane damping material 18-station turntable production line includes a sprocket box 1 with an opening on the rear end face, and a notch 10 for adding engine oil is opened on the top of the sprocket box 1; a bracket 11 is fixed at the upper part of the front side wall of the sprocket box 1, and a gear 13 is rotatably installed in the opening of the bracket 11, and a connecting shaft 130 is coaxially keyed at the gear 13, and a tooth seat 14 is meshed at the bottom of the gear 13, and a guide rod 15 is passed through the tooth seat 14, and springs 16 for pressing against the tooth seat 14 are provided at both ends of the guide rod 15; a support plate 17 is fixed at the rear end of the connecting shaft 130, and a baffle 18 for closing the notch 10 is fixed at the top of the support plate 17; a motor 2 is installed at the lower part of the front end face of the sprocket box 1; two symmetrical sprockets 3 are rotatably installed in the opening of the rear end face of the sprocket box 1, and a chain 4 is meshed between the two sprockets 3; the output shaft of the motor 2 is coaxially keyed with the sprocket 3 located below.

[0030] In this embodiment, the transmission shaft 30 is coaxially keyed to the upper sprocket 3, and a keyway 300 is provided on the outer wall of the transmission shaft 30. The transmission shaft 30 and the keyway 300 facilitate connection of the transmission shaft 30 with the transmission mechanism of the 18-station turntable production line, thereby facilitating transmission.

[0031] In this embodiment, the top of the sprocket box 1 is arc-shaped, the overall shape of the baffle 18 is arc-shaped, and the bottom end surface of the baffle 18 is in contact with the top of the sprocket box 1. This design ensures that the baffle 18 has a sealing effect on the gap 10.

[0032] In this embodiment, the baffle 18 and the support plate 17 are integrally formed, and the width of the baffle 18 is greater than the width of the notch 10. The integrally formed baffle 18 and support plate 17 have better connection strength, ensuring the service life of the baffle 18 and support plate 17, and the baffle 18 can better seal the notch 10.

[0033] In this embodiment, the overall shape of the bracket 11 is U-shaped, and the bracket 11 is fixedly connected to the outer wall of the sprocket box 1 by bolts. The U-shaped design provides a stable support for the connecting shaft 130, and the bolt fixing method ensures the installation reliability of the bracket 11.

[0034] In this embodiment, two connecting blocks 12 are fixed to the rear end of the outer walls of both sides of the sprocket box 1, and the outer walls of the connecting blocks 12 are provided with fixing holes 120. The setting of the fixing holes 120 facilitates the insertion of bolts, thereby facilitating the installation and fixing of the sprocket box 1 to the fixed platform by bolts.

[0035] In this embodiment, a lever 180 is fixed to the top of the baffle 18, and the lever 180 is fixedly connected to the baffle 18 by bolts. The lever 180 facilitates the movement of the baffle 18, thereby facilitating the movement of the baffle 18 to expose the gap 10.

[0036] In this embodiment, the front end of the connecting shaft 130 is rotatably connected to the bracket 11 through a bearing, and the rear end of the connecting shaft 130 is rotatably connected to the sprocket box 1 through a bearing. This design ensures the stability and smoothness of the connecting shaft 130 and the gear 13 when rotating.

[0037] It should be added that the sprocket 3 and chain 4 in this embodiment are both made of alloy steel. Alloy steel has stronger wear resistance, corrosion resistance, high temperature resistance and other properties, and is suitable for more severe working environments. The use of this material ensures the service life of the sprocket 3 and chain 4.

[0038] It is worth noting that the motor 2 involved in this embodiment is an existing conventional technology and will not be described in detail here.

[0039] During specific use, the user first pushes the lever 180 to move to one side, and the lever 180 drives the baffle 18 to move to one side. At this time, the baffle 18 drives the support plate 17 to rotate, and the connecting shaft 130 rotates and drives the gear 13 to rotate. Because the gear 13 is engaged with the gear seat 14, the gear seat 14 moves to one side, and the spring 16 on one side is compressed by the gear seat 14. When the baffle 18 disengages from the notch 10, the user stops pushing the lever 180, and finally the user pours engine oil onto the chain 4 through the notch 10.

[0040] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention. The scope of protection claimed in the present invention is defined by the appended claims and their equivalents.
