DETAILED DESCRIPTION

[0024] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] like Figure 1-6 As shown, the utility model provides an automatic door 2 device for an air shower conveyor line. The automatic door 2 device is installed at the front and rear ends of the air shower room in the air shower conveyor line, that is, the front and rear ends of the articles entering the air shower room, so that after the articles are conveyed into the air shower room, they are in a relatively closed space for air shower cleaning, and at the same time, the high-cleanliness space can be prevented from being polluted by wind and dust.

[0026] The automatic door 2 device includes a frame 1 for supporting and connecting various components. The frame 1 is a rectangular frame structure and shares one frame 1 with various structural components of the air shower room, so that the structure is installed compactly. In this embodiment, the frame 1 is assembled using multiple sections of aluminum profiles with the same specifications and different lengths. Compared with the frame 1 made of steel, it is lighter and has higher strength and corrosion resistance, and is easy to process and assemble.

[0027] Two automatic doors 2 are slidably mounted at one end of the frame 1. The two automatic doors 2 move in the same direction or in opposite directions. The automatic door 2 is a rectangular plate structure. In order to reduce the weight of the automatic door 2, a structure of four horizontal bars and a thin plate embedded in the middle is adopted. The thickness of the middle thin plate is smaller than that of the horizontal bars. In order to reduce the load, the four horizontal bars are also made of lightweight materials such as aluminum profiles. Since the middle thin plate does not need to be subjected to force and mainly plays the role of isolating air, a lighter material such as carbon fiber material can be used.

[0028] Buffer pads 9 for reducing inertial force are installed on the opposite sides of the two automatic doors 2. During the operation of the air shower conveyor line, the two automatic doors 2 are opened or closed synchronously with the inflow end or outflow end of the items. During the closing process, the driving motors 5 of the two automatic doors 2 are controlled to brake so that the driving force of the automatic doors 2 is disconnected. However, the automatic doors 2 will still cause collision of the two automatic doors 2 due to the action of inertial force. The opposite sides of the automatic doors 2 are made of rigid materials, which will be damaged by the inertial collision of the automatic doors 2. Therefore, buffer pads 9 are fixedly installed on the opposite sides of the automatic doors 2, which can absorb and reduce the impact of external impact or vibration on objects, play a role in shock absorption and buffering, and protect objects from damage. In addition, when the automatic doors 2 are closed, the buffer pads 9 can also fill the gaps and have a sealing effect to prevent dust from entering the air shower room.

[0029] Specifically, the buffer pad 9 is made of rubber material. Rubber has high elasticity, can restore to its original shape after being stressed, can effectively absorb shock and vibration, has good wear resistance, can maintain a long service life under friction and wear environment, has good sealing, corrosion resistance, and is easy to process.

[0030] The left and right ends of the automatic door 2 are respectively provided with a slide bar 3, and a slide groove 4 is correspondingly provided on the automatic door 2. The slide bar 3 is in the shape of a long strip and is fixedly installed on the frame 1. It is used for guiding and positioning the automatic door 2 to ensure the stability and accuracy of the movement of the automatic door 2. The slide bar 3 is provided with a guide part, which cooperates with the slide groove 4 on the automatic door 2. The guide part on the slide bar 3 is subjected to special surface treatment such as chrome plating, which can reduce the friction resistance between the slide groove 4, reduce energy loss, and improve mechanical efficiency. The non-connected part of the slide bar 3 is provided with a rounded rectangular notch to ensure the strength of the force while reducing the dead weight.

[0031] Furthermore, micro rollers are rotatably installed at the four corners of the automatic door 2, and the rollers are installed in the slide groove 4. Their main function is to make the up and down sliding of the automatic door 2 smoother, and the movement of the automatic door 2 will not be obstructed or even stuck due to the driving force at a certain angle to the movement direction of the automatic door 2, so that the operation of the automatic door 2 is more stable and reliable.

[0032] A small drive motor 5 is installed above the automatic door 2. The drive motor 5 needs to accurately control the stroke of the automatic door 2. Preferably, the drive motor 5 is a stepper motor, which can accurately rotate to a specific position according to an input pulse signal, is easy to control, and can achieve precise displacement. It has a relatively simple structure, low cost, and has the characteristics of low speed and high torque.

[0033] A synchronous wheel 6 is installed on the output shaft of the driving motor 5, and a synchronous wheel 6 is also installed under the automatic door 2. A synchronous belt 7 is installed on the outer sides of the two synchronous wheels 6. The synchronous belt 7 transmission adopts the method of tooth-to-tooth interlocking to transmit power, which can achieve accurate speed ratio transmission and small transmission error; unlike belt transmission, there is no sliding because the tooth grooves of the rack are interlocked with the teeth of the belt, so the transmission efficiency is high and there will be no sliding loss; the interlocking transmission between teeth is adopted, the transmission is stable during the working process, no vibration and impact load are generated, and the transmission efficiency is high and the working noise is low.

[0034] An adjustment hole 15 is provided on the synchronous wheel 6 at one end of the frame 1 away from the driving motor 5 for tensioning the synchronous belt 7. The adjustment hole 15 is a rounded rectangular through hole, in which the connecting shaft 12 can move, and the width of the adjustment hole 15 is greater than the diameter of the connecting shaft 12, so that the synchronous belt 7 can be tensioned simply and quickly.

[0035] Specifically, a connecting shaft 12 is installed at each synchronous wheel 6 on the frame 1, and a bearing 13 is installed at the other end of the connecting shaft 12. The connecting shaft 12 mainly supports the synchronous wheel 6 to rotate or transmit torque. In order to ensure the smooth rotation of the connecting shaft 12, a bearing 13 supporting the rotation of the rotating shaft is installed at the other end of the rotating shaft.

[0036] The bearing 13 uses a seat bearing 13, which can be directly installed on the frame 1, and is easy to install. Due to the design of the housing structure of the seat bearing 13, it has a higher load-bearing capacity and can withstand larger radial and axial loads.

[0037] Furthermore, a coupling 14 is fixedly mounted on the output shaft of the driving motor 5, and the other end of the coupling 14 is fixedly mounted on the connecting shaft 12. The coupling 14 is specifically an elastic coupling 14, which uses elastic materials (such as rubber) to reduce shock and absorb vibration, has high transmission efficiency, less energy loss, and reduces the noise and vibration of the transmission system to a certain extent.

[0038] The two opposite ends of the synchronous belt 7 are respectively fixedly mounted with toothed plates 8, and the two toothed plates 8 are respectively fixedly connected to the two automatic doors 2. The toothed plates 8 are components for transmitting power, and are usually used in conjunction with the synchronous belt 7. The toothed plates 8 engage with the toothed plates on the synchronous belt 7 through the toothed plates (or toothed grooves) on the toothed plates to ensure accurate transmission and synchronous motion, avoid slippage and deviation, and ensure transmission efficiency and accuracy.

[0039] Tooth plates 8 are fixedly installed at both opposite ends of the synchronous belt 7. In this way, when the synchronous wheel 6 rotates, it drives the synchronous belt 7 to move linearly, and the synchronous belts 7 at the two opposite ends move synchronously in opposite directions, thereby driving their respectively connected automatic doors 2 to move synchronously in linear directions. The forward and reverse rotation of the synchronous wheel 6 corresponds to the same or opposite movement of the two automatic doors 2, respectively, and finally realizes the closing and opening action of the automatic door 2.

[0040] Further, an intermediate plate 11 is fixedly mounted at one end of each automatic door 2, and the intermediate plate 11 is fixedly connected to the tooth plate 8. Since the tooth plate 8 is a standard part with a fixed shape, the intermediate plate 11 is provided to connect the tooth plate 8 and the automatic door 2 for convenient use.

[0041] A sensor 10 for sensing the end position of the movement of the automatic door 2 is installed on the frame 1. The sensor 10 is a distance sensor 10. When the automatic door 2 approaches, it sends a signal to the controller, and the controller controls the forward and reverse rotation of the drive motor 5, thereby controlling the same direction or opposite direction movement of the automatic door 2. Specifically, a sensor 10 is installed at the closed position of the two automatic doors 2, and another sensor 10 is installed at the maximum limit position of the opposite movement of any automatic door 2, so that the opening and closing state of the automatic door 2 can be detected to achieve automatic control.

[0042] In order to facilitate installation and protect the components installed therein, an embedding seat 16 for accommodating and installing various components is installed on the frame 1. The embedding seat 16 is a rectangular body-shaped component, and the internal hollow structure is used to install the components therein, and the wall thickness is uniform. The embedding seat 16 specifically includes a seat body 161 and a cover plate 162. When installing the components, the cover plate 162 is opened, and after the installation is completed, the cover plate 162 is covered for dust prevention, and the hidden design looks more beautiful and generous.

[0043] The utility model discloses an automatic door 2 device of an air shower conveyor line, wherein a driving motor 5 is installed on a frame 1 to drive a synchronous wheel 6 to rotate, and the synchronous wheel 6 drives a synchronous belt 7 to move linearly, thereby realizing synchronous movement of the two automatic doors 2, and the two automatic doors 2 are respectively fixedly connected to two opposite ends of the synchronous belt 7 to realize the same direction or opposite direction movement of the two automatic doors 2, and the utility model has a compact structure and a high degree of automation, and can realize automatic closing and opening of the air shower room, thereby improving the cleaning efficiency of the articles in the air shower room, and can realize automatic conveying and cleaning of the articles in combination with the conveyor line, which is stable and reliable, effectively liberates the hands, and saves labor costs.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
