[0030] The pneumatic comb-type cigarette clip machine comprises a frame 1 and a flip plate 2 arranged on the frame. The middle parts of both sides of the flip plate 2 are rotatably hinged to the two sides of the frame. Specifically, the flip plate is rotatably connected to the frame 1 through the lug 206 and the rotating pin in the middle. The flip plate 2 can be flipped to a horizontal position or a vertical position (such as Figure 1-3 As shown, when the flip plate is in the horizontal position, the front of the flip plate has an assembly space 3 (that is, the discharge end of the female cigarette clip) for installing cigarette clips for tobacco leaves laid on the flip plate surface (that is, the plate 207), and the cigarette clips 4 include male cigarette clips 401 and female cigarette clips 402 (as shown in FIG. Figure 6-7 As shown in the figure, a lower push rod 9 for driving the female cigarette clamp to move upward is provided on the frame at the lower part of the assembly space, and an upper push rod 10 for driving the male cigarette clamp to move downward is provided on the frame at the upper part of the assembly space. The upper push rod 10 and the lower push rod 9 can be driven to work by a cylinder or an electric push cylinder, and the assembly space 3 is located in the space where the upper push rod 10 and the lower push rod 9 are raised and lowered.

[0031] The public cigarette holder 401 includes an inverted U-shaped tube 403 and steel needles 404 fixedly arranged and connected to the inverted U-shaped tube, and each steel needle forms a comb-teeth shape with the inverted U-shaped tube.

[0032] The female cigarette clip 402 is made of a groove-shaped material in a U shape, and the two side parts of the male cigarette clip are inserted into and limited in the two side parts of the female cigarette clip. The two side parts of the female cigarette clip have groove-shaped openings 407. The groove-shaped openings on the two side parts of the female cigarette clip and the two side parts of the male cigarette clip can be fastened by interference fit. However, with the increase in the number of uses, the groove-shaped openings are prone to deformation and expansion, thereby making it impossible to fix the male cigarette clip. The following uses an elastic mechanism to achieve connection.

[0033] The specific elastic mechanism is that elastic convex buttons 405 are provided on both sides of the male cigarette clamp, and through holes 406 for limiting the elastic convex buttons are provided on both sides of the female cigarette clamp. After the two sides of the male cigarette clamp are inserted into the two sides of the female cigarette clamp, the elastic convex buttons 405 cooperate with the through holes 406 to limit the male cigarette clamp from detaching from the female cigarette clamp.

[0034] The frame 1 is provided with a storage space 5 for storing a plurality of mother cigarette clips, which is located below the flip plate 2 at the horizontal position. The storage space 5 is in the shape of a rectangular parallelepiped and is used to store a plurality of mother cigarette clips. The storage space 5 is communicated with the assembly space 3. A clamping frame 6 is installed on the side of the storage space 5 away from the assembly space. The frame 1 is provided with guide grooves 7 for guiding the movement of the two sides of the clamping frame 6. The two sides of the clamping frame 6 are installed with tension springs 8 that can drive the clamping frame to move toward the assembly space. Since the clamping frame 6 has the function of Push the mother cigarette clip to The thrust of the assembly space 3 is then expanded due to the groove-shaped openings 407 on both sides of the female cigarette clamp after use (such as Figure 6 As shown in FIG. 1 ), when the first surface A of the blocking column 101 for supporting the first female cigarette clamp is a plane, the first female cigarette clamp is easily in an inclined state (as shown in FIG. Fig.11 , 12 As shown, that is, the upper end of the female cigarette clip is far away from the first surface A, and the lower end of the female cigarette clip is close to the first surface A), which may easily cause the male cigarette clip to be difficult to align and insert into the female cigarette clip, or the male cigarette clip inserted into the female cigarette clip is in a larger tilted state. When the upper push rod is intended to press the male cigarette clip downward, the upper push rod and the male cigarette clip are in a misaligned position. In order to overcome the above problem, adjustable bolts 15 for supporting the lower parts of both sides of the first female cigarette clip in the material storage space are installed on the blocking column 101 of the frame 1. Through the adjustment of the adjustable bolts 15, the position of the lower part of the first female cigarette clip is supported toward one side of the clamping frame 6, so as to keep the first female cigarette clip in an upright state as a whole, avoid the misalignment of the upper push rod and the male cigarette clip when pressing down, thereby ensuring that the male cigarette clip and the female cigarette clip are pressed together in the center.

[0035] The guide groove 7 is formed by an upper tube 701 and a lower tube 702 which are arranged in parallel and spaced apart on the frame. The clamping frame 6 is a rectangular frame 601 formed by fixing a plurality of tubes. Both sides of the clamping frame 6 extend out of the guide groove. A stopper 11 is provided on the outer side of the upper tube to limit the movement of the clamping frame into the assembly space.

[0036] The specific stopper 11 is bent, and the first end of the stopper is rotatably hinged on the outer side of the upper tube 701. The outer side of the upper tube 701 is provided with a limit screw 12 to prevent the stopper from rotating downward. A pin 13 for manually swinging the stopper is provided on the side of the stopper close to the second end. The second end of the stopper abuts against the wall of the cross bar in the length direction of the clamping frame to limit the movement of the clamping frame toward the assembly space. When it is necessary to place multiple mother cigarette clips in the storage space 5, the clamping frame 6 needs to overcome the tension of the tension spring 8 and move away. Move away from the assembly space 3, since the stop buckle 11 and the two side parts of the clamping frame 6 extend out of the guide groove, the operation can be completed by a single person (since the flip plate 2 is relatively long, if there is no limiting mechanism of the stop buckle 11, it requires the cooperation of multiple people to complete it. After designing this structure, it can be completed by a single person, that is, after the operator pulls one side of the clamping frame 6 to the initial position, the stop buckle 11 on this side is used to limit the position, and after the operator pulls the other side of the clamping frame 6 to the initial position, the stop buckle 11 on the other side is used to limit the position).

[0037] The outer side surface of the vertical rod of the clamping frame 6 is provided with a handle 14 for manually driving the clamping frame to move. The first end of the tension spring 8 is connected to the handle 14, and the second end of the tension spring is connected to the frame, or the second end of the tension spring is connected to the handle of the other opposite side station (such as Figure 1 As shown, Figure 1 The tension spring 8 in the figure is simplified in order to facilitate the display of other structures. The tension spring is a pre-stretched spring, that is, it has a pulling force to converge toward the middle).

[0038] Hand pull rings 201 are provided on both sides of the flip plate 2 near one end of the assembly space for facilitating manual flipping of the flip plate. The hand pull ring is an arc tube, a first end of which is fixed on the upper surface of the flip plate, and a second end of the arc tube is fixed on a column 202 (which can be a column with a rectangular cross-section). The column 202 is welded and fixed to the edges of both sides of the flip plate near one end of the assembly space, and a guide channel for the rise of the female cigarette clamp or the descent of the male cigarette clamp is formed between the column 202 and the blocking column 101 of the frame. The column 202 not only serves as a connecting component of the hand pull ring 201 to increase the connection stability of the hand pull ring 201, but also serves as a component of the guide channel to achieve a guiding effect for the rise of the female cigarette clamp or the descent of the male cigarette clamp.

[0039] In the material storage space 5, due to the pushing effect of the clamping frame 6, the mother cigarette clamps are tightly attached to each other, while in the assembly space 3, only one mother cigarette clamp is allowed to enter at a time. In order to prevent the next mother cigarette clamp (i.e., the mother cigarette clamp located on the rear side of the first mother cigarette clamp) from being pushed up by the lower push rod (due to the friction between the contact surfaces of the two mother cigarette clamps), a baffle 16 for limiting the rise of the next mother cigarette clamp is installed on the side of the upper tube 701 close to the assembly space. The baffle 16 can be an angle iron sheet, and its first side surface is fixedly connected to the inner side surface of the upper tube 701, and its second side surface is flush with the upper surface of the upper tube. On the one hand, the baffle 16 can limit the next mother cigarette clamp from being synchronously lifted, and on the other hand, it can increase the support area of ​​the flip plate.

[0040] Specifically, the flip plate 2 includes a frame 203 formed by welding a plurality of tube strips and a plate 207 fixed on the upper surface of the frame, wherein the frame 203 includes two side tube strips 204 and front and rear tube strips 205 welded together, wherein the middle portion of the side tube strip 204 is vertically fixedly connected with a lug 206, and the lug 206 is rotatably hinged to the outer end of the upper tube 701 through a rotating pin, when the flip plate is in a horizontal position, the side tube strip 204 is attached to the upper surface of the upper tube 701 to support the flip plate 2; when the flip plate is in a vertical position, the side tube strip is attached to the end surface of the outer end of the upper tube (the end surface is the outer end surface of the short column connecting the upper tube 701 and the lower tube 702), and this structure is conducive to improving the supporting effect of the flip plate 2 and maintaining the stability of the vertical position.

[0041] The rectangular frame 601 of the clamping frame 6 is provided with four convex columns 602 on one side facing the assembly space, and the convex columns 602 are respectively arranged on both sides of the clamping frame, and the spacing between the two convex columns is greater than the length of the female cigarette clip, and the protruding height of the convex columns is greater than the thickness of a female cigarette clip, so as to form a position to avoid the assembly space 3 between the four convex columns. When the four convex columns 602 are not provided, after the female cigarette clips in the storage space 5 are used up, the rectangular frame 601 will be attached to the blocking column 101, that is, the rectangular frame 60 1 enters the assembly space 3, so when the operator misoperates, the lower push rod rises and pushes the rectangular frame 601, and the clamping frame 6 and the rectangular frame 601 are restricted by the upper pipe 701 and cannot rise, resulting in damage to the cylinder or electric push cylinder that drives the lower push rod. By providing four protruding columns 602 on the side of the rectangular frame 601 facing the assembly space, after all the female cigarette clips in the storage space 5 are used up, there is still space between the rectangular frame 601 and the blocking column 101 for the lower push rod to rise.

[0042] Working method of pneumatic comb type cigarette clip weaving machine,

[0043] First, fresh tobacco leaves are laid on the upper surface of the turning plate, wherein the stems of the fresh tobacco leaves extend into the assembly space;

[0044] Then the first piece of female cigarette in the storage space rises under the action of the lower push rod;

[0045] Then place the male cigarette clip with the tip of the steel needle facing downwards and mate it with the female cigarette clip;

[0046] Then the upper push rod descends and the male cigarette clamp is completely pressed into the female cigarette clamp, completing the clamping and installation of the whole row of fresh tobacco leaves.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
