Description

Technical Field

[0001] The utility model relates to the field of plaster production and packaging equipment, and more specifically, the utility model relates to a cooling device for plaster production and packaging. Background Art

[0002] During the production process of plasters, the cut plasters need to be packaged. The packaging steps can be briefly described as follows: two pieces of packaging skin form a packaging bag and sandwich several plasters in the middle, and the hot pressing equipment performs hot pressing and sealing on the packaging bag along the four sides of the plaster (keeping a certain distance from the four sides of the plaster), and then the hot pressed packaging bag is cut according to the number of plasters.

[0003] In the above process, the packaging bags after heat pressing need to be cooled to reduce the stickiness of the slitting knife to the packaging bags on the cutting path, so as to ensure the neatness of the slitting edges. The existing cooling method is mostly to place the packaging bags on a conveyor belt, and to set up air cooling equipment on both sides of the conveyor belt so that the transmission belt can be cooled during the transportation of the packaging bags, thus killing two birds with one stone.

[0004] However, in the above process, the layout of the conveyor belt needs to occupy a large amount of space, and in actual operation, it has been proved that the time required for air cooling is generally less than the transportation time of the conveyor belt. Therefore, the above design causes a double waste of space and energy. Utility Model Content

In other cases, well-known structures, methods, implementations or operations are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0028] Example 1

[0029] like Figure 1-Figure 8 The utility model provides a cooling device for plaster production and packaging, including a frame 1, a cooling mechanism 2 and a power mechanism 5. The frame 1 is placed on the ground of the factory area. The frame 1 is generally used to be placed obliquely below the hot pressing equipment to facilitate receiving the packaging bags output from the hot pressing equipment. The packaging bags are as follows Figure 8The packaging shown contains several plasters.

[0030] The cooling mechanism 2 includes a transmission wheel 21, an embedded wheel 22, an air guide plate 23, a duct 24, and a baffle 25. The transmission wheel 21 and the embedded wheel 22 are fixedly connected alternately in sequence. The outermost transmission wheel 21 is connected to the external fan through the duct 24. The embedded wheel 22 is provided with an air outlet. The duct 24 can discharge the cold air transported by the external fan through the transmission wheel 21 and the embedded wheel 22 to the outside through the air outlet. The hot pressing part of the packaging bag and the embedded wheel 22 are arranged one by one.

[0031] Preferably, the diameter of the embedded wheel 22 is smaller than that of the conveying wheel 21, so that when the packaging bag contacts the conveying wheel 21, the normal discharge of cold air outward from the air outlet is not affected.

[0032] Specifically, one end of the conduit 24 is rotatably connected to the transmission wheel 21, and the other end is communicated with an external fan.

[0033] like Figure 6 Preferably, the air outlets on the embedded wheel 22 are arranged radially outward from the center of the embedded wheel 22. This design can evenly guide the cold air to the outside of the transmission wheel 21.

[0034] like Figure 7 Preferably, the air outlet opened on the embedded wheel 22 is arranged in a spiral shape outward from the center of the embedded wheel 22, and the spiral direction is selected according to the specific situation. In addition to evenly guiding the wind to the outside of the transmission wheel 21, this design also makes the output cold air have a certain tangential force, which is convenient for pushing the packaging bags located on the cold air blowing path to move in a certain direction. The greater the wind force, the greater the displacement.

[0035] The baffle 25 is fixed on the frame 1, and the baffle 25 and the air guide plate 23 are respectively arranged on both sides of the conveying wheel 21. The cold air output from the air outlet will be blocked by the air guide plate 23 and blown toward the baffle 25, thereby blowing the packaging bag located between the embedded wheel 22 and the baffle 25 toward the baffle 25, reducing the falling speed of the packaging bag and improving the cooling effect of the cold air on the hot pressing part of the packaging bag.

[0036] The air guide plate 23 is fixed on the frame 1. The air guide plate 23 is covered on the sides of the conveying wheel 21 and the embedded wheel 22 to partially block the cold air output from part of the air outlet in a partially enclosed form. The cross-sectional shape of the air guide plate 23 is an arc. The central angle of the arc is designed according to the specific situation. The smaller the central angle, the smaller the range of the cold air that can be guided.

[0037] Preferably, the cross-sectional shape of the air guide plate 23 is semicircular, and is symmetrically arranged with the baffle plate 25 , so that all the cold air can be output toward the air guide plate 23 through the semicircular air guiding effect.

[0038] Furthermore, the power mechanism 5 in the device includes a motor, a transmission belt and a pulley. The motor is installed on the frame 1. A pulley is fixed on the output shaft of the motor. A pulley is also fixed on the outermost transmission wheel 21. The two pulleys are connected by a transmission belt.

[0039] Example 2

[0040] like Figure 1-8 On the basis of Example 1, the device also includes a cutting mechanism 3, including a rotating rod 31 and a slitting knife 32. The rotating rod 31 is rotatably connected to the frame 1. A plurality of slitting knives 32 are fixed on the rotating rod 31. Each slitting knife 32 is arranged corresponding to a certain embedded wheel 22. The cold air blown out from the embedded wheel 22 cools the hot pressing part, and the slitting knife 32 cuts the cooled hot pressing part, thereby realizing the dual processing of cooling and cutting, eliminating the purpose of installing an additional conveyor belt to transport the plaster packaging bag.

[0041] In order to ensure the rotation speed of the slitting knife 32, the rotating rod 31 is connected to the motor through a gearbox. Specifically, the gearbox can be a common gear set. The rotating rod 31 is fixedly connected to gear one, and the output shaft of the motor is fixedly connected to gear two. Gear one and gear two can be directly meshed or meshed through several other gears. By changing the number of teeth, the purpose of increasing the rotation speed of the rotating rod 31 is achieved.

[0042] Example 3

[0043] like Figure 1-Figure 8 On the basis of Example 1 and Example 2, a guide mechanism 4 is further provided on the frame 1, including a guide plate 41 and an isolation ridge 42. The motor is installed on the inner side of the frame 1 and is located below the conveying wheel 21. The guide plate 41 is tilted and fixed on the frame 1, and the guide plate 41 is located above the motor. The cut packaging bags can be guided from the gap between the baffle 25 and the conveying wheel 21 to the outside of the frame 1 for unified collection.

[0044] The guide plate 41 is fixed with an isolating edge 42 , and the position of the isolating edge 42 is designed to correspond to the position of the embedded wheel 22 , so that the packaging bag cut into strips can slide between two corresponding isolating edges 42 .

[0045] In summary, the present application integrates the cooling and slitting functions, thereby eliminating the space occupied by the conveyor belt and utilizing the cooling and deceleration of wind pressure to ensure the cooling efficiency of the packaging bags.

[0046] The above only describes some exemplary embodiments of the present invention by way of illustration.
