Description

Technical Field

[0001] The invention relates to the technical field of laminar flow vehicles for pharmaceutical industry, and more particularly to a protective door for a laminar flow vehicle. Background Art

[0002] The clean laminar flow vehicle is a one-way flow type local air purification device and is a special supporting equipment for the pharmaceutical industry. It is equipped with a dedicated rechargeable power supply, which is not restricted by the location of the power supply and can circulate raw materials, semi-finished products, products or tools. Laminar flow vehicles are equipped with openable material doors to enable the removal and placement of materials. The laminar flow vehicles in the prior art are manually operated during the transportation and material handling process, and the opening time and opening range of the material door cannot be controlled. This leads to the possibility of large-scale contact between the internal environment of the laminar flow vehicle and the external environment, which can easily cause internal contamination of the laminar flow vehicle and result in substandard quality of the transported materials.

DETAILED DESCRIPTION

[0023] The core of the present invention is to provide a laminar flow vehicle protective door, which adopts an upper and lower layered design to control the opening range of the protective door and reduce the internal pollution of the laminar flow vehicle.

[0024] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0025] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] With reference to the accompanying drawings, Figure 1 It is a schematic diagram of the three-dimensional structure of a laminar flow vehicle with a laminar flow vehicle protective door of the present invention; Figure 2 It is a schematic diagram of the three-dimensional structure of a laminar flow vehicle with a laminar flow vehicle protective door of the present invention after removing the door frame cover; Figure 3 It is a schematic diagram of the main structure of the laminar flow vehicle with the laminar flow vehicle protective door of the present invention after the door frame cover is removed; Figure 4 It is a right view structural schematic diagram of a laminar flow vehicle with a laminar flow vehicle protective door of the present invention after removing the door frame cover; Figure 5 The diagram is a left-side structural schematic diagram of a laminar flow vehicle with a laminar flow vehicle protective door according to the present invention after removing the door frame cover.

[0027] In a specific embodiment, Figures 1 to 5 As shown, a laminar flow vehicle protective door is arranged at the opening of the door frame cover 2, and a side wall of the laminar flow vehicle body 1 is set as the door frame cover 2. The laminar flow vehicle protective door of the present invention includes a lower door 3 and an upper door 4. The door panels of the lower door 3 and the upper door 4 are in the same vertical plane, and the top surface of the lower door 3 can be in close contact with the bottom surface of the upper door 4. The lower door 3 and the upper door 4 simultaneously seal and block the opening of the door frame cover 2.

[0028] When the laminar flow vehicle is docked with the sterilization cabinet or the filling room, it is often necessary to carry out the entry and exit of materials at different heights. Therefore, in order to facilitate the automated entry and exit of materials, the height of the protective door of the laminar flow vehicle is made relatively high. Therefore, the protective door is made into a structure of a lower door 3 and an upper door 4, which can be opened separately, reducing the opening amplitude, reducing the area in contact with the external environment, and thus reducing the internal pollution of the laminar flow vehicle. At the same time, because the door panels of the lower door 3 and the upper door 4 are in the same vertical plane, rather than the traditional overlapping design, it can prevent the back of the outer door and the face of the inner door from being contaminated by the ambient air and then transferred to the interior of the laminar flow vehicle. The protective door of the laminar flow vehicle of the present invention adopts an upper and lower layered design to control the opening amplitude of the protective door and reduce the internal pollution of the laminar flow vehicle.

[0029] In a specific embodiment of the present invention, Figures 2 to 5 As shown, both the lower door 3 and the upper door 4 are sliding doors that open upwards, and the lower door 3 and the upper door 4 are driven by corresponding driving mechanisms to open and close.

[0030] An air filter assembly is provided on the top of the laminar flow vehicle, that is, the top height space is relatively large, which is convenient for storing the door panel that slides upward to open.

[0031] Specifically, if Figures 2 to 5 As shown, the driving mechanism includes a first optical rod 5, a second optical rod 6, a first lead screw 7 and a second lead screw 8 installed along the sliding opening direction of the sliding door. The first optical rod 5 and the first lead screw 7 are arranged on the left side of the door frame cover 2, and the second optical rod 6 and the second lead screw 8 are arranged on the right side of the door frame cover 2.

[0032] The first support plate 301 and the second support plate 302 are fixedly connected at both ends of the inner side of the door panel of the lower door 3, respectively. The first support plate 301 and the second support plate 302 are both L-shaped plates. The head bolts of the L-shaped plates are connected to the door panel of the lower door 3. A guide sleeve is arranged on the main plate of the L-shaped plate. The guide sleeve is slidably connected to the first light rod 5 or the second light rod 6.

[0033] The inner sides of the upper door 4 are respectively fixedly connected with the fourth support plate 401 and the sixth support plate 403, both of which are L-shaped plates, the head bolts of the L-shaped plates are connected to the upper door 4, the main plate of the L-shaped plate is provided with a guide sleeve, the guide sleeve is slidably connected to the first light rod 5 or the second light rod 6, the main plate of the fourth support plate 401 is also provided with a second threaded sleeve 802, the second threaded sleeve 802 is threadedly connected to the second lead screw 8;

[0034] The first lead screw 7 and the second lead screw 8 are driven by the first drive motor 701 and the second drive motor 801 arranged at the bottom. The first drive motor 701 and the second drive motor 801 are specifically servo motors, which are convenient for controlling the opening of the lower door 3 and the upper door 4.

[0035] The lower door 3 and the upper door 4 are driven by the lead screw slider structure, and the opening range can be precisely controlled. In addition, the double light bar guide ensures the stability of the door panel during sliding operation. When materials need to be put in and out at the bottom of the protective door, the first drive motor 701 and the second drive motor 801 run synchronously to drive the first lead screw 7 and the second lead screw 8 to rotate synchronously, the first threaded sleeve 702 drives the first support plate 301 to drag the lower door 3, and the second threaded sleeve 802 drives the fourth support plate 401 to drag the upper door 4, and the lower door 3 and the upper door 4 open upward synchronously. When materials need to be put in and out at the top of the protective door, the first drive motor 701 does not run, the second drive motor 801 drives the second lead screw 8 to rotate, and the second threaded sleeve 802 drives the fourth support plate 401 to drag the upper door 4 upward to open separately. The upper door 4 is opened separately, the opening range is reduced, and the ambient air caused by the large door opening area is avoided from entering the laminar flow vehicle and polluting the interior.

[0036] Specifically, if Figure 4 As shown, the door panel of the lower door 3 is also fixedly connected to the third support plate 303, and the third support plate 303 is an L-shaped plate. The head bolts of the L-shaped plate are connected to the door panel of the lower door 3. A guide sleeve is provided on the main plate of the L-shaped plate. The guide sleeve is slidably connected to the second light rod 6 and is located above the second support plate 302.

[0037] The third support plate 303 is provided to assist in supporting the door panel of the lower door 3 , thereby forming a stable three-point support, so that the lower door 3 can smoothly move up and down along the guide of the light bar.

[0038] Specifically, if Figure 4 As shown, the door panel of the upper door 4 is also fixedly connected to the fifth support plate 402, the fifth support plate 402 is an L-shaped plate, the head bolt of the L-shaped plate is connected to the door panel of the upper door 4, a guide sleeve is arranged on the main plate of the L-shaped plate, the guide sleeve is slidably connected to the second light rod 6, and a third threaded sleeve 803 is also arranged on the main plate of the fifth support plate 402, and the third threaded sleeve 803 is threadedly connected to the second lead screw 8.

[0039] The fifth support plate 402 is provided to assist in supporting the door panel of the upper door 4, thereby forming a stable three-point support, so that the upper door 4 can smoothly move up and down along the guide of the light bar.

[0040] In a specific embodiment of the present invention, Figure 2 , Figure 3 and Figure 5As shown, it also includes a bottom mounting plate 101, a top mounting plate 102 and a door mounting plate 103, and the upper and lower ends of the first light rod 5 and the second light rod 6 are respectively mounted on the bottom mounting plate 101 and the top mounting plate 102. The upper and lower ends of the second lead screw 8 are respectively mounted on the bottom mounting plate 101 and the top mounting plate 102 through bearing seats. The bottom end of the first lead screw 7 is mounted on the bottom mounting plate 101 through a bearing seat, and the top end of the first lead screw 7 is mounted on the door mounting plate 103 through a bearing seat; the bottom mounting plate 101, the top mounting plate 102 and the door mounting plate 103 are all arranged on the mounting frame inside the laminar flow vehicle body 1, and the door mounting plate 103 is located below the top mounting plate 102; furthermore, the length of the first lead screw 7 is less than that of the second lead screw 8.

[0041] The first lead screw 7 is used to drive the lower door 3 . The length of the first lead screw 7 is shorter than that of the second lead screw 8 , which reduces the cost of raw materials and increases the stability of the first lead screw 7 .
