Description

Technical Field

[0001] The utility model relates to the field of drying, in particular to drying equipment with adjustable air volume. Background Art

[0002] Textile production includes the drying process, and the drying effect will affect the quality of textiles, especially chemical fiber fabrics, which have high requirements for the uniformity of air volume when drying. The existing drying device adopts an upper and lower nozzle structure. The cloth moves between the two nozzles, and the upper and lower nozzles blow hot air to the upper and lower surfaces of the cloth for drying. However, due to the different distances between the air outlets of the two nozzles, the air volume of the two nozzles is different, resulting in uneven upper and lower air volume. Also, because some cloths have different humidity levels on the upper and lower sides, the upper and lower air volumes also need to be flexibly adjusted to ensure the drying effect.

[0003] The existing drying device has multiple air regulating mechanisms arranged at different positions in the nozzle. The air regulating mechanism is composed of components such as an air regulating plate, a rotating shaft, a handle, a compression spring, a positioning pin and a positioning tooth. The air regulating plate is rotated by manually rotating the handle to make the air output different, thereby achieving the purpose of adjusting the air output. However, the structure is complex, with many components and high cost. The coordination of multiple components is prone to connection failure and unreliability. Moreover, multiple air regulating mechanisms need to be adjusted, and the desired air output effect can only be achieved through their mutual coordination. It may even be necessary to adjust multiple times, which is slow, time-consuming, labor-intensive and labor-intensive. Utility Model Content

[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail with reference to the accompanying drawings. It is hereby stated that the directional words such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the utility model are only based on the accompanying drawings of the utility model, and are not specific limitations of the utility model.

[0029] See also Figure 1-5 The utility model discloses a drying device with adjustable air volume, comprising a drying device, wherein the drying device comprises an air supply mechanism, an air regulating mechanism and a nozzle assembly.

[0030] The air regulating mechanism includes an air regulating seat 1, a driving mechanism 2 and an air regulating baffle 3, wherein the driving mechanism 2 is connected to the air regulating baffle 3, and the air regulating seat 1 is provided with a connected air regulating cavity and an air inlet; the air supply mechanism is connected to the air regulating seat 1, and the air supply mechanism is used to transport air into the air regulating cavity through the air inlet.

[0031] The nozzle assembly includes an upper nozzle 5 and a lower nozzle 6, a cloth passage 7 is provided between the upper nozzle 5 and the lower nozzle 6, and the upper nozzle 5 and the lower nozzle 6 are respectively provided with an upper spray hole (not shown) and a lower spray hole 62 arranged toward the cloth passage 7, and the upper spray hole and the lower spray hole 62 are respectively connected to the air inlet through the air regulating cavity. Specifically, the upper spray hole and the lower spray hole 62 are respectively provided on the side of the upper nozzle 5 and the lower nozzle 6 facing the cloth passage 7.

[0032] The air regulating baffle 3 is arranged in the air regulating cavity and extends to the air inlet. The air regulating baffle 3 is driven by the driving mechanism 2 to change the air flow area of ​​the air inlet connected with the upper spray hole and the lower spray hole 62 respectively.

[0033] The utility model provides an air-adjusting mechanism for the drying device with adjustable air volume, and utilizes a driving mechanism to drive the air-adjusting baffle to move back and forth. Since the air-adjusting baffle divides the air inlet into two air inlets, and the two air inlets are respectively connected to the upper spray hole and the lower spray hole, the movement of the air-adjusting baffle can change the area of ​​the two air inlets, thereby changing the air volume entering the upper nozzle and the lower nozzle, achieving the purpose of adjusting the air volume on the upper and lower sides of the cloth in the cloth passage, and meeting the drying requirements of the cloth, especially the chemical fiber fabric.

[0034] Preferably, the driving mechanism 2 is a motor. More preferably, the motor is a servo motor.

[0035] Specifically, Figure 3 As shown, the air regulating baffle 3 divides the air inlet into an upper air inlet 11 and a lower air inlet 12, and the air regulating baffle 3 divides the air regulating chamber into an upper air outlet channel 13 and a lower air outlet channel 14. The upper air inlet 11, the upper air outlet channel 13 and the upper spray hole are connected in sequence, and the lower air inlet 12, the lower air outlet channel 14 and the lower spray hole 62 are connected in sequence. The air supply mechanism delivers air to the air inlet. Due to the separation of the air regulating baffle, the air inlet is divided into an upper air inlet and a lower air inlet, and the air regulating chamber is divided into an upper air outlet channel and a lower air outlet channel. The hot air passes through the upper air inlet and the lower air inlet, enters the upper air outlet channel and the lower air outlet channel respectively, and then enters the upper nozzle and the lower nozzle, and finally blows into the cloth channel through the upper spray hole and the lower spray hole to dry the upper and lower sides of the cloth. Due to the movement of the air regulating baffle, the area of ​​the upper air inlet and the lower air inlet changes, so as to achieve the purpose of adjusting the air volume of the upper nozzle and the lower nozzle.

[0036] More specifically, Figure 2-4 As shown, the upper nozzle 5 is provided with an upper spray cavity 51, and the lower nozzle 6 is provided with a lower spray cavity 61; the upper air inlet 11, the upper air outlet channel 13, the upper spray cavity 51 and the upper spray hole are connected in sequence, and the lower air inlet 12, the lower air outlet channel 14, the lower spray cavity 51 and the lower spray hole 62 are connected in sequence. Therefore, the hot air is blown out through the upper air inlet, the upper air outlet channel, the upper spray cavity and the upper spray hole in sequence, and the hot air is blown out through the lower air inlet, the lower air outlet channel, the lower spray cavity and the lower spray hole in sequence.

[0037] Preferably, the cross-sectional area of ​​the upper spray chamber 51 gradually decreases from the side close to the air regulating seat 1 to the side away from the air regulating seat 1; the cross-sectional area of ​​the lower spray chamber 61 gradually decreases from the side close to the air regulating seat 1 to the side away from the air regulating seat 1. By limiting the cross-sectional areas of the upper spray chamber and the lower spray chamber, it is avoided that the overall wind speed of the nozzle is uneven due to the higher wind speed on the side of the nozzle close to the air regulating seat.

[0038] Further, if Figure 3 As shown, the air regulating baffle 3 includes a connecting plate 31 and an adjusting plate 32 connected to each other, the connecting plate 31 is connected to the driving mechanism 2, and the adjusting plate 32 extends to the air inlet.

[0039] Preferably, the cross-sectional shape of the regulating baffle 3 is L-shaped, so as to facilitate separation of the air regulating cavity and the air inlet.

[0040] Preferably, the connecting plate 31 and the adjusting plate 32 are integrally formed, so that the structure of the air regulating baffle is firm and strong.

[0041] More preferably, the wind regulating baffle 3 further includes a reinforcing plate 33, and the reinforcing plate 33 is respectively connected to the connecting plate 31 and the adjusting plate 32. A triangular structure is formed between the connecting plate, the adjusting plate and the reinforcing plate, which further makes the structure of the wind regulating baffle more solid and stronger, and avoids deformation in strong winds.

[0042] Preferably, if Figure 1 , 3 -4, the air regulating mechanism also includes a transmission assembly arranged on the air regulating seat 1, and the transmission assembly includes a ball screw 41, a screw nut 42 and a connecting seat 43, and the driving mechanism 2, the ball screw 41, the screw nut 42, the connecting seat 43 and the connecting plate 31 are connected in sequence. Specifically, the driving mechanism drives the ball screw to rotate, the ball screw and the screw nut are threadedly connected, the screw nut and the connecting seat are fixedly connected, and the connecting seat and the connecting plate are fixedly connected. The ball screw rotates, causing the screw nut to move back and forth along the axial direction of the ball screw, thereby driving the air regulating baffle to move forward and backward to change the wind flow area of ​​the upper air inlet and the lower air inlet, and then adjust the air volume entering the upper spray chamber and the lower spray chamber.

[0043] Going further, Figure 1-3 As shown, the air supply mechanism includes an air supply seat 8 and a fan 9 installed on the air supply seat 8, and the air supply seat 8 is provided with an air supply cavity 81, and the air supply cavity 81 is connected to the air inlet. The fan 9 is preferably a centrifugal fan. The fan blades are arranged in the air supply cavity, and the hot air blown into the air supply cavity is guided to the air inlet by the action of the fan blades. It should be noted that the air supply seat 8 is arranged at the bottom of the air regulating seat 1, and the air outlet and air inlet of the air supply cavity 81 are connected.

[0044] like Figure 1-2As shown in 4-5, the utility model also includes a wind control device (not shown in the figure), the air supply seat 8 is provided with an air inlet 82 connected to the air supply cavity 81, and the wind control device is connected to the air inlet 82. The wind control device includes a heater and a fan, the fan blows the heat generated by the heater to the air inlet, and the fan guides the heat to the air inlet. Among them, the wind control device can adopt the existing technical structure, which will not be described in detail here.

[0045] In addition, if Figure 1 , 4 -5, an air supply seat 8 may be provided with two air supply chambers 81, the two air supply chambers 81 are not connected to each other, and fans 9 are installed respectively. An air adjustment seat 1 may be provided with two air adjustment chambers, the two air adjustment chambers are not connected to each other, and are connected to two groups of nozzle assemblies respectively. The driving mechanism 2 and the transmission assembly are arranged between the two air adjustment chambers, and the air adjustment baffle 3 extends from the transmission assembly to the air adjustment chambers on both sides. The utility model can adjust the air volume of two groups of nozzle assemblies at the same time by driving an air adjustment baffle 3, with high adjustment efficiency and low cost.

[0046] In summary, the utility model provides a drying device with adjustable air volume, which effectively realizes air volume regulation, has a simple and reliable structure, and has high regulation efficiency.
