Description

Technical Field

[0001] The utility model relates to the technical field of casting machinery and equipment, in particular to an improved synchronous encoding device for a casting machine. Background Art

[0002] The synchronous encoding device of the pouring machine is used to synchronously transmit the movement signal of the sand box molding line to the pouring machine, so as to control the pouring machine to move synchronously with the sand box and realize automatic pouring of the sand box. However, due to the gap between the sand boxes on the molding line, in order to ensure that the receiving signal of the synchronous encoding device is not interrupted, two rollers with gaps are usually required to receive the sand box movement signal.

[0003] For example, in the patent document with patent number CN202022046930.4 authorized for publication on May 4, 2021, a synchronization device for an automatic pouring machine is disclosed, which receives the movement information of the sand box through roller one and roller two set in a gap and connected by transmission, and transmits the information to the encoder through the driving wheel. In this way, even if the molding line moves to the gap position between the two sand boxes, the other roller can continue to roll under the action of the sand box to continuously transmit the molding line movement signal to control the synchronous operation of the pouring machine. However, this synchronization device is usually customized for a specific molding line, and the distance between the two rollers on the synchronization device is fixed, which makes it only applicable to the synchronization signal transmission work of a single type of molding line. When the size of the sand box on the molding line changes (large and small castings) or the distance between adjacent sand boxes changes, the use of the synchronization device is still limited and its applicability is poor. Utility Model Content

[0004] In order to solve the technical problem mentioned in the above background technology that the roller spacing of the existing synchronization device is fixed, resulting in limitations in its use and poor applicability, the utility model provides an improved casting machine synchronization encoding device.

[0005] The technical solution of this utility model is as follows:

[0006] An improved synchronous encoding device for a casting machine is arranged on one side of a molding line and is used to synchronously transmit the displacement information of the sand box on the molding line to the casting machine. The device includes a support unit and a mounting plate at its upper end. A synchronization unit is installed on the mounting plate, and the synchronization unit is used to complete the reception and transmission of the sand box movement information on the molding line.

[0007] As the main technical concept of the present invention, the mounting plate is vertically arranged, the upper end of the support unit is connected to the rear side of the mounting plate, the synchronization unit includes two driving wheel groups arranged at the same height, and a passive wheel group arranged for vertical sliding, wherein one of the driving wheel groups is elastically slidably arranged on the mounting plate in the horizontal direction, and the direction of the elastic force is directed to the side away from the other driving wheel group, the passive wheel group is connected to a driving device that drives it to slide vertically, and the passive wheel group is not collinear with the two driving wheel groups, the driving wheel group and the passive wheel group respectively include a driving wheel and a passive wheel located on the front side of the mounting plate, the passive wheel is connected to the encoder for transmission, and surrounds the two driving wheels with And a passive wheel is provided with a synchronous belt. The active wheel is located on the upper side of the sand box on the molding line, and the lower side is in contact with the sand box. The movement information of the sand box is synchronized to the passive wheel through the synchronous belt, and then the synchronous reception and transmission of the information is completed through the encoder. Moreover, due to the horizontal elastic sliding setting of one of the active wheel groups and the vertical sliding setting of the passive wheel group, the vertical sliding setting of the passive wheel group is driven by the control driving device, and the sliding active wheel group can be driven to move under the action of the synchronous belt, and then the spacing between the two active wheel groups can be adjusted, so that the device can be suitable for the transmission of movement information of molding lines with different sand box sizes or sand box spacings, which significantly expands the scope of application of the device.

[0008] As described above, in an improved synchronous encoding device for a casting machine, the lowest height that the passive wheel can reach is higher than the height of the active wheel, ensuring that only the active wheel of the device can contact the sand box, thereby ensuring that the device can accurately and effectively complete the work of transmitting the movement information of the sand box.

[0009] As a preferred embodiment, the driving wheel group fixedly connected to the mounting plate is the first driving wheel group, the driving wheel group slidingly connected to the mounting plate is the second driving wheel group, and the passive wheel group is arranged close to one side of the first driving wheel group, so that the adjustment of the second driving wheel group by the synchronous belt can be more labor-saving, and at the same time, the distance adjustment range of the two driving wheel groups is increased, further expanding the scope of application of the device.

[0010] Further preferably, the shape of the synchronous belt is not an obtuse triangle, that is, the vertical plane where the rolling axis of the passive wheel is located is located between the vertical planes where the rolling axes of the two driving wheels are located, so that the synchronous belt can better contact the two driving wheels, ensuring that the movement of the driving wheel can be smoothly transmitted to the passive wheel through the synchronous belt.

[0011] As described above, an improved synchronous encoding device for a casting machine is provided with a first slide groove horizontally on the mounting plate, and the second driving wheel group is slidably arranged in the first slide groove through the first slider. A second elastic telescopic rod is also provided in the first slide groove, one end of which abuts against the inner side of one end of the first slide groove close to the first driving wheel group, and the other end abuts against the first slider. The second elastic telescopic rod can keep the synchronous belt in a tensioned state at all times, ensuring that the reception and transmission of the movement information of the device can proceed normally.

[0012] It should be noted that the maximum elongation length of the second elastic telescopic rod is not less than the length of the first slide groove, ensuring that the synchronous belt can always be tensioned under the action of the two driving wheels and the driven wheel, thereby ensuring that the driving wheel and the driven wheel can always rotate synchronously.

[0013] As described above, an improved synchronous encoding device for a casting machine, the supporting unit includes a mounting rod, a connecting rod and a first elastic telescopic rod, the mounting rod is vertically arranged, the middle part of the connecting rod is rotatably connected to one end of the mounting rod, and the rotation plane of the connecting rod is vertical, the two ends of the first elastic telescopic rod are respectively rotatably connected to one end of the connecting rod and the middle part of the mounting rod, the connecting rod is connected to the mounting plate away from one end of the first elastic telescopic rod, ensuring that the driving wheel can always be in contact with the sand box under the action of the first elastic telescopic rod, and when there is a protrusion on the rolling track of the driving wheel on the sand box, the driving wheel can bounce up normally to prevent it from hard contact with the sand box to cause the wheel to jump or damage the driving wheel structure, thereby ensuring the accuracy of receiving the sand box movement information.

[0014] Furthermore, a sliding sleeve is provided in the middle of the mounting rod, and the first elastic telescopic rod is rotatably connected to the sliding sleeve at one end away from the connecting rod. By adjusting the height of the sliding sleeve, the height of the mounting plate can be adjusted to adjust the height of the driving wheel, thereby ensuring that when the height of the sand box changes, the device can still better complete the reception and transmission of mobile information, thereby further increasing the applicability of the device.

[0015] Furthermore, the sliding sleeve is provided with fastening bolts and can be fixed in position by the fastening bolts to ensure that the setting height of the driving wheel is stable.

[0016] As described above, an improved synchronous encoding device for a casting machine, the driving wheel includes a large wheel and a small wheel inside the large wheel, the lower side of the large wheel is in contact with one side of the upper end of the sand box, and is used to receive the displacement information of the sand box, the synchronous belt is wound around the outside of the small wheel, and the small wheel has the same specifications as the driven wheel, ensuring that the number of rotations of the driving wheel and the driven wheel match, so that the synchronization work of the sand box movement information can be more accurate.

[0017] The beneficial effects of the present invention are as follows: the present invention is an improved synchronous encoding device for a casting machine, which is provided with two driving wheel groups arranged at the same height and a passive wheel group arranged for vertical sliding through a mounting plate, wherein one driving wheel group is elastically slidably arranged laterally, and the passive wheel group is connected to a driving device for driving its vertical sliding. By controlling the driving device to drive the passive wheel group to slide vertically, the sliding driving wheel group can be driven to move under the action of a synchronous belt, and then the spacing between the two driving wheel groups can be adjusted, so that the device can be suitable for the transmission of movement information of molding lines with different sand box sizes or sand box spacings, which significantly expands the scope of application of the device.

There is a synchronous belt 7, and the driving wheel 31 is located on the upper side of the sand box on the molding line, and the lower side is in contact with the sand box. The movement information of the sand box is synchronized to the passive wheel 51 through the synchronous belt 7, and then the synchronous reception and transmission of the information is completed through the encoder 6. Moreover, due to the horizontal elastic sliding setting of one of the driving wheel groups, the passive wheel group 5 is vertically slid. By controlling the driving device to drive the passive wheel group 5 to slide vertically, the sliding driving wheel group can be driven to move under the action of the synchronous belt 7, and then the spacing between the two driving wheel groups can be adjusted, so that the device can be suitable for the transmission of movement information of molding lines with different sand box sizes or sand box spacings, which significantly expands the scope of application of the device. The detailed structure of the synchronous encoding device is described below.

[0031] In this embodiment, combined with Figure 4 The driving wheel group fixedly connected to the mounting plate 2 is the first driving wheel group 3, and the first driving wheel group 3 is located on one side of the mounting plate 2.

The first slider 41 includes a clamping block 411, a sliding block 412, and a clamping piece 413. The clamping block 411 is located on one side of the first slide groove 21 near the front end of the mounting plate 2, and the sliding block 412 is located between the two extended parts.

[0035] It should be noted that the maximum elongation length of the second elastic telescopic rod 42 is not less than the length of the first slide groove 21, ensuring that the synchronous belt 7 can always be tensioned under the action of the two driving wheels 31 and the driven wheel 51, thereby ensuring that the driving wheel 31 and the driven wheel 51 can always rotate synchronously.

[0036] In this embodiment, combined with Figure 5 The mounting plate is also provided with a second vertically arranged slot 22, and the passive wheel group 5 is slidingly connected to the second slot 22 through a second slider 52. The second slot 22 and the second slider 52 cooperate in the same manner as the first slot 21 and the first slider 41, and no further elaboration is given here. The passive wheel 51 is rotationally connected to the second slider 52 through a second wheel axle.

[0037] As a preferred embodiment, the second chute 22 is located on the side of the mounting plate 2 close to the first driving wheel group 3, that is, the passive wheel group 5 is located close to the side of the first driving wheel group 3, so that the adjustment of the second driving wheel group 4 by the synchronous belt 7 can be more labor-saving, and the distance adjustment range of the two driving wheel groups is increased, further expanding the scope of application of the device.
