Description

Technical Field

[0001] The utility model belongs to a feeding and discharging port device, which is mainly applied to spiral quick-freezers, tunnel quick-freezers, etc. Background Art

[0002] The feeding and discharging port device is mainly used to reduce cold leakage. That is, on the door opening of the storage board, a door opening buckle plate is used in a riveting form for corner covering, and then a door curtain is directly spot-welded on the door opening buckle plate. Due to the large temperature difference between the inside and outside of the storage body door opening, there is often condensed water on the upper surface of the storage body above it, and then it flows down along the door opening buckle plate and drips onto the surface of the product, affecting the freezing effect of the product. At the same time, due to the production requirements of different products, to adjust the height of the door curtain, it is necessary to disassemble the door curtain and then spot-weld it on the door opening buckle plate, and the adjustment is relatively complex. Summary of the Invention

[0003] The purpose of the utility model is to overcome the above deficiencies and provide a feeding and discharging port device that is convenient to disassemble and has a good freezing effect.

[0004] The purpose of the utility model is achieved through the following technical solutions: a feeding and discharging port device, including a frame, the frame is fixed on the outer ring of the door opening on the storage body, the frame includes an upper hole frame buckle plate, a lower hole frame buckle plate, a left hole frame buckle plate and a right hole frame buckle plate. The upper frame buckle plate, the lower hole frame buckle plate, the left hole frame buckle plate and the right hole frame buckle plate are all U-shaped bending plates. One end of the upper hole frame buckle plate is provided with a water guiding groove. The two sides of the lower hole frame buckle plate are inclined inward. A door curtain fixing groove plate is arranged between the upper parts of the front sides of the left hole frame buckle plate and the right hole frame buckle plate. Waist-shaped holes are arranged at both ends of the door curtain fixing groove plate. The door curtain fixing groove plate is fixed by press riveting screws and knurled nuts. A door curtain is arranged below the door curtain fixing groove plate.

[0005] A further improvement of the utility model lies in that: the frame is riveted and connected to the inside and outside of the storage body through open-type flat head blind rivets.

[0006] A further improvement of the utility model lies in that: the corner lap joints of the upper hole frame buckle plate, the lower hole frame buckle plate, the left hole frame buckle plate and the right hole frame buckle plate are all 45° rounded corners.

[0007] A further improvement of the utility model lies in that: the inclination angle of the water guiding groove is 85°.

[0008] A further improvement of the utility model lies in that: an inclined surface with an inclination of 10° is arranged between the guiding water groove and the upper hole frame buckle plate.

[0009] A further improvement of the utility model lies in that: the two sides of the lower hole frame buckle plate are inclined inward by 6°.

[0010] A further improvement of the utility model lies in that: inclined surfaces with an inclination of 10° are arranged at the bottoms of the front sides of the lower hole frame buckle plate, the left hole frame buckle plate and the right hole frame buckle plate.

[0011] A further improvement of the utility model lies in that the bottom panels of the left hole frame buckle plate and the right hole frame buckle plate are inclined.

[0012] The utility model has the following advantages compared with the prior art:

[0013] A water guide groove (with an inclined angle bending edge) is arranged above the outer side of the upper hole frame buckle plate, which is conducive to condensation water dripping on it. At the same time, due to the inclined angle, the condensation water will be concentrated and drained from one end. The two sides of the lower hole frame buckle plate are inclined inward, and the bottom panels of the left hole frame buckle plate and the right hole frame buckle plate are inclined, all of which are conducive to draining the condensation water into the interior of the storage body. Holes are added to the left hole frame buckle plate and the right hole frame buckle plate, and knurled nuts are press riveted before bending. There are oblong holes formed by laser on the curtain fixing mounting plate. After adjusting the height, the curtain is fixed to the curtain fixing groove plate with press riveted screws and knurled nuts. When adjustment is needed, just remove the press riveted screws for adjustment. The utility model can ensure that the condensation water will not drip onto the product, and at the same time, the curtain is convenient for adjustment. Description of the Drawings

Detailed Implementation Modes

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. The elements and features described in one embodiment of the present utility model can be combined with the elements and features shown in one or more other embodiments. It should be noted that for the sake of clarity, the representation and description of components and processes unrelated to the present utility model and known to those of ordinary skill in the art are omitted. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0021] As Figures 1 to 5 shown, a feeding and discharging port device includes a frame, which is fixed to the outer ring of the doorway on the library body 6, that is, the frame is riveted to the inside and outside of the library body 6 through open-type flat head blind rivets 5. The frame includes an upper hole frame buckle plate 1, a lower hole frame buckle plate 2, a left hole frame buckle plate 3, and a right hole frame buckle plate 4. The upper hole frame buckle plate 1, the lower hole frame buckle plate 2, the left hole frame buckle plate 3, and the right hole frame buckle plate 4 are all U-shaped bent plates. A water guide groove 7 is provided at one end of the upper hole frame buckle plate 1. The two sides of the lower hole frame buckle plate 2 are inclined inward. A curtain fixing groove plate 8 is provided between the upper parts in front of the left hole frame buckle plate 3 and the right hole frame buckle plate 4. Waist-shaped holes 9 are provided at both ends of the curtain fixing groove plate 8. The curtain fixing groove plate 8 is fixed through press rivet screws 10 and knurled nuts 11. A curtain 12 is provided below the curtain fixing groove plate 8.

[0022] The corners of the upper hole frame buckle plate 1, the lower hole frame buckle plate 2, the left hole frame buckle plate 3, and the right hole frame buckle plate 4 are all 45° rounded corners to prevent collisions.
