The transmission actuator requires frequent maintenance, the transmission reliability is poor, the operation stability is low, and large mechanical shock fluctuations will be generated when starting. The transmission mechanism needs to be set in the direction of the trolley's operation, which increases the length and space occupied by the equipment. Utility Model Content

[0004] The utility model provides a linear reciprocating movable trolley pin gear transmission drive device adopts the following technical solutions:

[0005] A linear reciprocating movable trolley pin gear transmission drive device includes a driving mechanism for driving a feeding trolley to perform linear reciprocating movement and an auxiliary support mechanism for vertically supporting the feeding trolley. The driving mechanism includes a driving motor, the driving motor is connected to a reducer, and the reducer is connected to a driving pin gear. A driven pin shaft is installed on the feeding trolley along its own length direction, and the driving pin gear is engaged with the driven pin shaft.

[0006] By adopting the above technical solution, the drive device adopts a smaller drive layout to occupy a larger space, thereby achieving a larger feeding trolley running range; the same configuration of drive devices are set on both sides of the feeding trolley, which can ensure that the force on both sides of the feeding trolley is uniform and not tilted, and can also ensure the synchronization of the dual-drive operation; when maintaining the pin gear transmission, only part of the pin shaft can be replaced according to the wear condition of the transmission mechanism, and the pin shaft is easy to process and replace, with a short processing cycle, which effectively saves equipment maintenance time, improves operational reliability and stability, and reduces the mechanical shock fluctuation during startup.

[0007] Optionally, the driven pin shaft is installed at the bottom of the feeding trolley, and the driving pin gear is arranged vertically.

[0008] By adopting the above technical solution, the driven pin shaft is set at the bottom of the feeding trolley, which can effectively prevent the trolley from being deformed by force and dust from falling into the transmission pair to affect the operation.

[0009] Optionally, the driven pin shaft is installed on the side of the feeding trolley, and the driving pin gear is arranged horizontally.

[0010] By adopting the above technical solution, the driving mechanisms on both sides clamp the feeding trolley in the middle, which can also prevent the feeding trolley from running away during operation.

[0011] Optionally, the auxiliary support mechanism includes a guide rail, a support seat and a support wheel. The guide rail is installed at the bottom of the feeding trolley along the length direction of the feeding trolley. The support seat is arranged below the guide rail. The support wheel is rotatably connected to the support seat. The support wheel is in rolling contact with the guide rail and provides vertical support force.

[0012] By adopting the above technical solution, the support wheels roll and support the guide rails, and the rolling friction reduces the travel obstacles, which facilitates the smooth travel of the feeding trolley and provides strong vertical support for the feeding trolley.

[0021] The following is combined with Figure 1 -Attached Figure 3 The utility model is described in further detail.

[0022] The embodiment of the utility model discloses a linear reciprocating movable trolley pin gear transmission driving device. Example 1

[0023] Reference Figure 1 There are two sets of pin-tooth transmission drive devices for the linear reciprocating movable trolley. The two sets of drive devices are located on different sides of the feeding trolley 1. The drive device includes a drive mechanism 2 and an auxiliary support mechanism 3.

[0024] Reference Figure 1 and Figure 2 The driving mechanism 2 is arranged horizontally, and includes a driving motor 20. A reducer 21 is installed on the driving motor 20. The reducer 21 is connected to the active pin gear 23 through a bearing seat 22. The active pin gear 23 is arranged vertically. A driven pin shaft 24 is installed along the length direction at the bottom of the feeding trolley 1. The active pin gear 23 is engaged with the driven pin shaft 24, thereby driving the feeding trolley 1 to perform linear reciprocating motion.

[0025] Reference Figure 1 and Figure 2 The auxiliary support mechanism 3 includes a guide rail 30, which is installed at the bottom of the feeding trolley 1 and arranged along the length direction of the feeding trolley 1. A support seat 31 is provided under the guide rail 30, and a support wheel 32 is rotatably connected to the support seat 31. The guide rail 30 is in rolling contact with the support wheel 32 and the support wheel 32 provides vertical support force. By using the auxiliary support mechanism 3, the active pin gear 23 is prevented from directly bearing vertical pressure.

[0026] The implementation principle of the pin-tooth transmission drive device of the linear reciprocating movable trolley of Example 1 of the present invention is: the driving motor 20 transmits power to the feeding trolley 1 through the reducer 21, the active pin gear 23 and the driven pin shaft 24 in sequence, and uses the pin-tooth transmission to convert the circular motion of the driving motor 20 and the reducer 21 into the linear motion of the feeding trolley 1.

[0027] The driving devices are arranged on both sides of the middle of the reciprocating travel area of ​​the feeding trolley 1. A smaller driving arrangement occupies space, so as to achieve a larger running range of the feeding trolley 1; the driving devices with the same configuration are arranged on both sides of the feeding trolley 1, which can ensure that the force on both sides of the feeding trolley 1 is uniform and not tilted, and can also ensure the synchronization of the dual-drive operation; the driven pin shaft 24 is arranged at the bottom of the feeding trolley 1, which can effectively prevent the trolley from being deformed by force and dust from falling into the transmission pair to affect the operation.

[0028] Compared with traditional wire rope drive equipment, the space occupied by the drive equipment in the running direction of the feeding trolley 1 is eliminated. During the maintenance of the pin gear transmission, only part of the pin shaft can be replaced according to the wear condition of the transmission mechanism. The pin shaft is easy to process and replace, and the processing cycle is short, which effectively saves equipment maintenance time, improves operational reliability and stability, and reduces the mechanical shock fluctuation during startup. Example 2

[0029] Reference Figure 3 The difference between this embodiment and embodiment 1 is that the driving mechanism 2 in this embodiment is vertically arranged on the side of the feeding trolley 1, wherein the active pin gear 23 is arranged horizontally, and the driven pin shaft 24 is installed on the side wall of the feeding trolley 1, and the active pin gear 23 and the driven pin shaft 24 are engaged with each other.

[0030] The implementation principle of the linear reciprocating movable trolley pin gear transmission drive device of embodiment 2 of the present invention is: the driving mechanism 2 is placed vertically to further reduce the occupied space projection area and improve space utilization; when placed vertically, the driving mechanisms 2 on both sides clamp the feeding trolley 1 in the middle, which can also play a role in preventing the feeding trolley 1 from running away during operation.

[0031] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
