Description

Technical Field

[0001] The invention relates to the technical field of cigarette production equipment, in particular to a continuous cutting rod-shaped material conveying device and a production method. Background Art

[0002] During the filling and production process of granular heat-not-burn cigarettes, it is necessary to provide fixed-length cut firmware or filter rods online. Currently, the filling machine adopts intermittent filling, and the rod segments also adopt intermittent feeding. Each time, a rotating groove wheel rotates several base rods for online cutting.

[0003] After the rod segments are cut, they fall into the lower material receiving area due to their own weight, or fall into the lower material receiving area due to the positive pressure air applied in the teeth of the rotating groove wheel. When the speed of the cutting groove wheel increases, the cut rod segments will be stuck in the teeth of the groove wheel. The above method cannot ensure that all the cut rod segments are separated at one time. Entering the cutting knife box again will cause problems such as rod segment cutting, affecting the online cutting quality. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention aims to provide a continuous cutting rod-shaped material conveying device and production method, through the positive pressure blowing and the assistance of the driven brush, the rod segments can quickly fall into the sliding chute. In order to achieve the above purpose, the present invention is implemented by the following technical solutions:

[0005] In a first aspect, the present invention provides a continuous slitting rod-shaped material conveying device, comprising:

[0006] The blanking baffle assembly is in the shape of a groove, and a driven brush assembly is arranged in the groove and can rotate with the slitting groove wheel. A plurality of positive pressure air blowing joints are arranged on one side wall of the groove, and the spacing between the positive pressure air blowing joints is different from the spacing between the teeth of the slitting groove wheel, so as to ensure that positive pressure air is always blown into the teeth of the slitting groove wheel during the rotation of the slitting groove wheel; when arranged in relative positions, the positive pressure air blowing joint acts before the driven brush assembly and the slitting groove wheel;

[0007] The lower slide chute assembly is arranged obliquely, and the top end is connected to the bottom of the blanking baffle assembly.

[0008] As a further implementation, the blanking baffle assembly is surrounded by a plurality of baffles, and the positive pressure air blowing joint and the brush shaft of the driven brush assembly are mounted on the same baffle.

[0009] As a further implementation, the baffle on the opposite side where the positive-pressure air blowing joint and the driven brush assembly baffle are installed is a transparent baffle.

[0010] As a further implementation, the transparent baffle and the adjacent baffle are closed or opened by magnets.

[0011] As a further implementation, a brush is fixed to the brush shaft by means of screws.

[0012] As a further implementation, the brush shaft is mounted on the baffle through a seat bearing.

[0013] As a further implementation, the lower slide chute assembly includes a lower slide chute and a screen bottom plate, and the screen bottom plate is installed in the lower slide chute and is spaced apart from the bottom thereof.

[0014] As a further implementation, the baffles on both sides of the lower sliding groove are transparent baffles.

[0015] As a further implementation, a waste box is further included, which is arranged at the bottom of the lower slide chute and the opening of the screen bottom plate at the bottom end.

[0016] In a second aspect, the present invention provides a production method for continuously cutting rod-shaped materials, which is carried out using the continuous cutting rod-shaped material conveying device as described in the first aspect, and comprises the following steps:

[0017] After the rod-shaped material at the cutting groove wheel is cut, the fixed-length rod segments are formed and enter the position of the blanking baffle assembly under the continuous rotation of the cutting groove wheel. Under the action of their own gravity and the positive pressure air provided by the positive pressure blowing joint, the rod segments gradually fall into the sliding chute assembly and slide down to the downstream storage hopper. Some rod segments remaining in the tooth grooves of the cutting groove wheel continue to rotate with the cutting groove wheel and pass through the driven brush assembly. The brush installed on the brush shaft and the cutting groove wheel generate driven rotation to scrape the remaining rod segments off the cutting groove wheel; when the rod segments enter the sliding chute assembly and pass through the screen bottom plate, the debris or powder mixed in the rod segments are screened and separated from the complete rod segments, and the complete rod segments slide down along the screen bottom plate to the downstream storage hopper, and the debris or powder passes through the bottom of the screen and falls into the bottom of the sliding chute, and finally slides down and falls into the waste box, completing the separation of the rod segments and debris.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The driven brush assembly provided in the material baffle assembly of the present invention can rotate with the slitting groove wheel. When individual rod segments fail to fall smoothly after the rear positive pressure blowing, the rod segments rotate with the slitting groove wheel and pass through the driven brush assembly. The driven brush assembly and the slitting groove wheel generate driven rotation, so that the driven brush assembly is scraped away from the slitting groove wheel by the brush, which further ensures the complete separation of the rod segments and the slitting groove wheel.

[0020] 2. The baffle plate of the blanking baffle assembly of the present invention is provided with a plurality of positive pressure air blowing joints with different spacings, and the spacings of the positive pressure air blowing joints are different from the spacings of the groove wheel teeth, which can ensure that positive pressure air is always blown into the tooth grooves of the slitting groove wheel during the rotation of the slitting groove wheel, thereby ensuring that the rod segments after slitting are fully affected by the positive pressure air and fall smoothly.

[0021] 3. The plexiglass door provided on the front side of the blanking baffle assembly of the present invention is fixed to the front baffle by hinges. The plexiglass door is provided with magnets on both sides that are attracted to the left and right fixed supports. The internal blanking situation can be observed through the transparent plexiglass door, and the plexiglass door can be opened to replace and repair the brush.

[0022] 4. A screen bottom plate is provided in the sliding chute of the present invention. When the rod segment enters the lower sliding chute assembly and passes through the screen bottom plate, the debris or powder mixed in the rod segment is screened and separated from the complete rod segment. The complete rod segment slides down along the screen bottom plate to the downstream storage hopper, and the debris or powder passes through the bottom of the screen and falls into the bottom of the sliding chute, and finally slides down and falls into the waste box, completing the separation of the rod segment and the debris.

[0023] 5. The plexiglass cover plate located on the lower slide chute of the present invention is fixed above the lower slide chute by bolts, which can provide dust protection for the cut rod segments in the lower slide chute and observe the sliding of the rod segments. If material accumulation or poor sliding, an air gun can be used to assist in cleaning through the front plexiglass door of the blanking baffle assembly, which is easy to operate and observe.

[0035] In a typical embodiment of the present invention, reference is made to Figure 1 As shown, a continuous slitting rod-shaped material conveying device includes a material drop baffle assembly 1, a lower slide chute assembly 2 and a waste box 3. The material drop baffle assembly 1 is fixed on the frame panel and is located directly below the slitting groove wheel. The lower slide chute assembly 2 is connected below the material drop baffle assembly 1. The waste box 3 is arranged at the bottom of the lower slide chute assembly 2.

[0036] like Figure 2 , Figure 3 and Figure 4 As shown, the blanking baffle assembly 1 is in the shape of a groove, in which a driven brush 113 assembly 104 is provided and can rotate with the slitting groove wheel, and a plurality of positive pressure blowing joints 111 are provided on one side wall of the groove, and the spacing between the positive pressure blowing joints is different from the spacing between the teeth of the slitting groove wheel to ensure that positive pressure air is always blown into the teeth of the slitting groove wheel during the rotation of the slitting groove wheel; when arranged in relative position, the positive pressure blowing joint acts on the slitting groove wheel before the driven brush 113 assembly 104.

[0037] The driven brush assembly 104 provided in the blanking baffle assembly 1 of the present embodiment can rotate with the slitting groove wheel. When individual rod segments fail to fall smoothly after the rear positive pressure blowing, the rod segments rotate with the slitting groove wheel and pass through the driven brush assembly 104. The driven brush assembly 104 and the slitting groove wheel generate driven rotation, so that the driven brush assembly 104 is scraped away from the slitting groove wheel by the brush, further ensuring the complete separation of the rod segments and the slitting groove wheel.

[0038] In addition, the baffle plate of the blanking baffle assembly 1 of this embodiment is provided with a plurality of positive pressure air blowing joints 111 with different spacings, and the spacings of the positive pressure air blowing joints 111 are different from the spacings of the groove wheel teeth, which can ensure that positive pressure air is always blown into the grooves of the slitting groove wheel teeth during the rotation of the slitting groove wheel, thereby ensuring that the rod segments after slitting are fully affected by the positive pressure air and fall smoothly.

[0039] The driven brush assembly 104 comprises a brush 113, a brush shaft 110 and a seat bearing 109. The brush shaft 110 is fixed with a brush 113 by screws. There are multiple brushes 113, which can be disassembled and replaced when damaged.

The fixed support 102 is fixed to the panel, the rear baffle 101 is connected to the rear of the fixed support 102 by bolts, the front baffle 106 is connected to the front of the fixed support 102 by bolts, and the transparent baffle is arranged above the front baffle 106.

[0042] The positive pressure air blowing joint and the brush shaft 110 of the driven brush assembly 104 are installed on the same baffle. In this embodiment, the brush shaft 110 of the driven brush assembly 104 is fixed on the seat bearing 109, the seat bearing 109 is installed on the rear side of the rear baffle 101 by bolts, the brush 113 is fixed on the brush shaft 110 by screws, and the brush shaft 110 is fixed on the seat bearing 109 by a shaft elastic ring 114. The positive pressure air blowing joint 111 is also fixed behind the rear baffle 101.

[0043] The baffle plate opposite to the baffle plate with the positive pressure air blowing connector and the driven brush assembly 104 is a transparent baffle plate. In this embodiment, the transparent baffle plate is an organic glass door 103, which cooperates with the front baffle plate 106 through a hinge 107. The organic glass door 103 and the adjacent baffle plate are closed or opened through a magnet 108, and the magnet 108 is installed on the organic glass door 103 through a bolt. A handle 105 is provided in front of the organic glass door 103 to facilitate the opening or closing of the organic glass door 103.

[0044] The plexiglass door 103 provided on the front side of the blanking baffle assembly 1 of this embodiment is fixed to the front baffle 106 by a hinge 107. The plexiglass door 103 is provided with magnets 108 on both sides that are attracted to the left and right fixed supports 102. The internal blanking situation can be observed through the transparent plexiglass door 103, and the plexiglass door 103 can be opened to replace and repair the brush 113.

[0045] like Figure 1As shown, the lower slide chute assembly 2 is tilted, and the top end is connected to the bottom of the blanking baffle assembly.

[0047] like Figure 1 and Figure 6 As shown, a waste box 3 is also included, and the waste box 3 is arranged at the bottom of the lower slide chute 201 and the opening of the screen bottom plate 202 at the bottom end.

[0048] When the rod segment enters the lower slide chute assembly 2 and passes through the screen bottom plate 202, the debris or powder mixed in the rod segment is screened and separated from the complete rod segment, and the complete rod segment slides down along the screen bottom plate 202 to the downstream storage hopper, and the debris or powder passes through the bottom of the screen and falls into the bottom of the slide chute 201, and finally slides down and falls into the waste box 3, completing the separation of the rod segment and the debris.

[0049] The baffles on both sides of the lower slide chute 201 are transparent baffles. In this embodiment, the transparent baffle is an organic glass cover plate 203 fixed on the upper side of the lower slide chute 201. The organic glass cover plate 203 located on the lower slide chute 201 is fixed on the upper side of the lower slide 201 by bolts, which can provide dust protection for the cut rod segments in the lower slide chute 201 and observe the sliding of the rod segments. If there is material accumulation or the sliding is not smooth, an air gun can be used to assist in cleaning through the organic glass door on the front side of the blanking baffle assembly, which is convenient to operate and easy to observe.
