A track is fixedly connected below the upper door seal, and the track is slidably connected to two drive modules, the drive module includes a pulley block, a pulley frame, and a drive motor, and a drive rod for connecting to the left sponge door curtain or the right sponge door curtain is fixedly connected below the pulley frame, and a position sensor for detecting the position of the car is installed on the drive rod, and the position sensor is electrically connected to a PLC controller.

[0005] Preferably, the pulley block comprises two upper pulleys and one lower pulley, the two upper pulleys are arranged above the track, and the lower pulley is arranged below the track.

[0006] Preferably, the driving motor is connected to the lower pulley.

[0007] Preferably, the left door seal is provided with a left storage groove for storing a left sponge door curtain, and the right door seal is provided with a right storage groove for storing a right sponge door curtain.

[0008] Compared with the prior art, the advantages and positive effects of the utility model are:

[0009] The utility model drives the left / right sponge door curtain to move through the driving module, and detects the position of the carriage through the position sensor. When the left / right sponge door curtain is close to the carriage, the position sensor at the edge of the left / right sponge door curtain can detect the carriage and feedback to the PLC controller, and the PLC controller turns off the driving motor. Therefore, the utility model can realize the automatic turning off of the driving motor when the left / right sponge door curtain is close to the carriage.

[0010] The utility model has a simple structure, is easy to manufacture and is suitable for use. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] In order to more clearly illustrate the technical solutions of the embodiments of the utility model, the following is a brief introduction to the drawings required for use in the description of the embodiments.

DETAILED DESCRIPTION

[0017] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the retractable sponge door seal includes an upper door seal 1, a left door seal, and a right door seal. The upper door seal 1 includes an upper sponge door curtain 11, the left door seal includes a left sponge door curtain 21, and the right door seal includes a right sponge door curtain 31. In order to make the motor-driven sponge door curtain automatically stop after it is in contact with the carriage, the utility model is fixedly connected with a track 12 below the upper door seal 1, and the track 12 is slidably connected with two drive modules 4. The drive module 4 includes a pulley block, a pulley frame 43, and a drive motor 44. The pulley block is installed on the pulley frame 43, and the drive motor 44 drives the pulley frame 43 to move. A drive rod 45 for connecting with the left sponge door curtain 21 or the right sponge door curtain 31 is fixedly connected below the pulley frame 43. Specifically, the drive rod 45 is connected to the edge of the left / right sponge door curtain 31 so that the drive rod 45 is close to the carriage. A position sensor 5 for detecting the position of the carriage is installed on the drive rod 45, and the position sensor 5 is electrically connected to a PLC controller (not shown in the figure).

[0020] Specifically, for the left door seal 2 and the right door seal 3, the driving module 4 drives the left / right sponge door curtain 31 to move so that it is close to the car, and then after the position sensor 5 detects the car, the PLC controller controls the driving motor 44 to stop. Compared with the truck that may park on the left or right, the height of the truck car is fixed, so the upper sponge door curtain 11 can be set to hang naturally, and the utility model is not described in detail here.
