Description

Technical Field

[0001] This utility model belongs to the field of tobacco filter rod forming technology, specifically relating to a granular filter rod feeding device. Background Technology

[0002] With the development of the cigarette filter rod industry, various more aesthetically pleasing and functional filter rods are becoming increasingly popular. Among them, granular filter rods are made by solidifying fine granular materials. During the solidification process, the uniformity of the particle distribution on the yarn belt directly affects the weight and draw resistance of the granular filter rod. Therefore, the addition of particles, as the initial process, plays a crucial role in the weight and draw resistance of the granular filter rod. Current technology typically uses a feeder to add particles. The particles output by the feeder fall onto the yarn belt by gravity and then follow the yarn belt into the forming gun for solidification. However, regardless of whether the feeder outputs particles evenly, uneven particle distribution on the yarn belt is common after the particles fall, thus affecting the forming quality of the granular filter rod. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a particle filter rod feeding device that improves the uniformity of particle distribution on the yarn.

[0004] This utility model includes a hopper located above the front bottom plate assembly of a cigarette gun. The front bottom plate assembly of the cigarette gun is provided with a guide groove for the movement of the yarn. The bottom of the hopper is provided with a protrusion extending into the guide groove and spaced apart from the inner wall of the guide groove. The bottom of the protrusion is provided with a discharge port communicating with the inside of the hopper. It also includes a feeding wheel and a rotary drive. The feeding wheel is rotatably disposed inside the end of the hopper facing downstream of the guide groove. The side wall of the end of the hopper facing downstream of the guide groove is provided with an opening. The opening is laterally connected to the protrusion. The feeding wheel passes through the opening and the discharge port. The rotation axis of the feeding wheel is arranged along the width direction of the guide groove. The lowest point of the feeding wheel surface is lower than the top of the guide groove. The rotary drive is used to drive the feeding wheel to rotate.

[0005] Furthermore, there is a gap between the end face of the feeding wheel and the inner wall of the discharge port, and the width of the gap is smaller than the diameter of the particles.

[0006] Furthermore, a limit stop is provided at the bottom of the bottom of the protruding strip opposite to the opening.

[0007] Furthermore, it also includes a support frame on which the hopper is mounted, and the installation height of the hopper is adjustable.

[0008] Furthermore, the hopper is mounted on the upright frame via an adjustment assembly, which includes a fixed block, a movable block, and a locking component. The fixed block is disposed on the upright frame, the movable block is slidably connected to the fixed block, and the sliding direction of the movable block is set along the height direction of the upright frame. The hopper is disposed on the movable block, and the locking component is used to fix the position of the movable block.

[0009] Furthermore, the fixed block is provided with a wedge-shaped groove, and the moving block is provided with a wedge-shaped slider, which passes through the wedge-shaped groove.

[0010] Furthermore, the adjustment assembly also includes an adjustment screw, a bracket is provided on the fixed block, the adjustment screw is rotatably mounted on the bracket, and the adjustment screw is threadedly connected to the moving block.

[0011] Furthermore, the adjustment assembly also includes a limiting plate, one end of which is fixed to the side of the moving block, and the other end of which is provided with an oblong hole. The length of the oblong hole is set along the height direction of the upright, and the side of the fixed block is provided with a threaded hole. The locking component is a locking screw, which passes through the oblong hole and connects to the threaded hole.

[0012] Furthermore, the lower ends of the hopper are inclined inward on both sides.

[0013] Furthermore, the bottom of the front base plate assembly of the cigarette gun is provided with several through holes that communicate with the feed guide groove.

[0014] The beneficial effects of this invention are that the discharge port at the bottom of the hopper is directly located in the guide groove on the front bottom plate assembly of the filter gun, which allows the yarn belt to move. Particles are directly carried out by the yarn belt along the discharge port, avoiding the dispersion process when particles fall freely and improving the uniformity of particle distribution on the yarn belt. Furthermore, by setting a rotatable feeding wheel inside the hopper at the downstream end of the guide groove, as the feeding wheel rotates in the corresponding direction, some particles can be pressed onto the yarn belt, helping to fill the gaps in the yarn belt area at the bottom downstream of the discharge port. Simultaneously, the particles carried out by the yarn are compacted at the downstream end of the discharge port, making the hopper discharge more uniform and further improving the uniformity of particle distribution on the yarn belt, thereby improving the forming quality of the granular filter rod.

[0020] like Figures 1-4 As shown, this utility model provides a granular filter rod feeding device, including a hopper 1, a feeding wheel 2, and a rotary drive 3. The hopper 1 is located above the front bottom plate assembly 6 of the cigarette gun, which is the feeding end of the formed cigarette gun. The front bottom plate assembly 6 is provided with a guide groove 63 for the movement of the yarn. A protrusion 11 is provided at the bottom of the hopper 1, extending into the guide groove 63 and spaced apart from the inner wall of the guide groove 63, without affecting the normal movement of the yarn. A discharge port 12 communicating with the inside of the hopper 1 is provided at the bottom of the protrusion 11, and the discharge port 12 passes through the bottom of the protrusion 11. The feeding wheel 2 is rotatably disposed inside the end of the hopper 1 facing downstream of the guide groove 63. The downstream direction of the guide groove 63 is downstream of the direction of movement of the yarn within the guide groove 63. Figure 2 Taking a perspective example, the yarn moves from the right end to the left end of the guide trough 63 within the guide trough 63, with the left end of the guide trough 63 being the downstream direction. The hopper 1 has an opening on one side wall facing the downstream direction of the guide trough 63. The opening is laterally connected to the protruding strip 11 and the discharge port 12. The feeding wheel 2 passes through the opening and the discharge port 12, and the rotation axis of the feeding wheel 2 is set along the width direction of the guide trough 63. Specifically... Figure 1 Taking the perspective as an example, the length direction of the guide trough 63 is... Figure 1 In the Y-axis direction, the direction in which the yarn moves along the guide groove 63 is also the length direction of the guide groove 63, and the width direction of the guide groove 63 is... Figure 1 The rotation axis of the feeding wheel 2 is set along the X-axis direction. The lowest point of the feeding wheel 2 is lower than the top of the guide groove 63, and the rotary drive 3 is used to drive the feeding wheel 2 to rotate.

[0021] The filter rod feeding device provided by this utility model has a discharge port 12 at the bottom of the hopper 1 directly located in the guide groove 63 on the front bottom plate assembly 6 of the cigarette gun, which allows the yarn belt to move. The particles are directly carried out by the yarn belt along the discharge port 12, avoiding the dispersion process when the particles fall freely and improving the uniformity of particle distribution on the yarn belt. By setting a rotatable feeding wheel 2 inside the end of the hopper 1 facing downstream of the guide groove 63, as the feeding wheel 2 rotates in the corresponding direction, it can press some particles onto the yarn belt, helping to fill the particles missing on the yarn belt area at the bottom downstream of the discharge port 12. At the same time, it can compact the particles carried out by the yarn at the downstream end of the discharge port 12, making the discharge from the hopper 1 more uniform and further improving the uniformity of particle distribution on the yarn belt, thereby improving the forming quality of the granular filter rod.

[0022] In this invention, there is a gap between the end face of the feeding wheel 2 and the inner wall of the discharge port 12. The width of the gap is smaller than the diameter of the particles. Based on this setting, it can be ensured that the feeding wheel 2 rotates normally in the hopper 1, and the particles will not fall down along the gap between the end face of the feeding wheel 2 and the inner wall of the discharge port 12, thus ensuring the reliability of the feeding wheel 2.

[0023] The rotary drive component 3 is located on the outer side of the hopper 1. A rotating shaft is located in the middle of the feeding wheel 2, which rotates within the hopper 1 via the shaft. The end of the shaft extends to the outside of the hopper 1. The output end of the rotary drive component 3 is connected to the rotating shaft. This rotary drive component 3 can be a motor or other mechanism. Figure 2 Taking the perspective as an example, the rotation direction of the feed wheel 2 is... Figure 2 Clockwise direction from the perspective.

[0024] A limit stop 111 is provided at the bottom of the protrusion 11 opposite to the outlet, which is used to block the particles at the end of the discharge port 12 opposite to the outlet, so as to prevent the particles from moving upstream of the guide trough 63 and improve the stability of feeding.

[0025] This utility model also includes a support frame 4, on which the hopper 1 is installed. The installation height of the hopper 1 is adjustable. By adjusting the installation height of the hopper 1, the distance between the bottom of the discharge port 12 and the bottom of the guide trough 63 can be adjusted, thereby adjusting the amount of granules fed.

[0026] Specifically, the hopper 1 is mounted on the upright frame 4 via an adjusting assembly 5. The adjusting assembly 5 includes a fixed block 51, a movable block 52, and a locking component. The fixed block 51 is disposed on the upright frame 4, and the movable block 52 is slidably connected to the fixed block 51. The sliding direction of the movable block 52 is set along the height direction of the upright frame 4. The hopper 1 is disposed on the movable block 52, and the locking component is used to fix the position of the movable block 52. The height position of the hopper 1 can be adjusted by the relative sliding of the movable block 52 and the fixed block 51. After adjustment, the position of the movable block 52 is fixed by the locking component.

[0027] The fixed block 51 is provided with a wedge-shaped groove 511, and the moving block 52 is provided with a wedge-shaped slider 521, which passes through the wedge-shaped groove 511. Based on this configuration, the fixed block 51 and the moving block 52 adopt a wedge-shaped sliding fit, which not only achieves relative sliding between the moving block 52 and the fixed block 51, but also provides a more stable fit between the moving block 52 and the fixed block 51, preventing loosening in the depth direction of the wedge-shaped groove 511.

[0028] The adjustment assembly 5 also includes an adjustment screw 54. A bracket 53 is provided on the fixed block 51. The adjustment screw 54 is rotatably mounted on the bracket 53 and is threadedly connected to the moving block 52. Based on this configuration, by rotating the adjustment screw 54, the moving block 52 can be driven to slide along the fixed block 51, thereby adjusting the height position of the hopper 1. The operation is convenient, quick, and highly stable.

[0029] The adjustment assembly 5 also includes a limiting plate 55. One end of the limiting plate 55 is fixed to the side of the moving block 52, and the other end of the limiting plate 55 is provided with a waist-shaped hole 551. The length direction of the waist-shaped hole 551 is set along the height direction of the upright 4, and the side of the fixed block 51 is provided with a threaded hole 512. The locking component is a locking screw 56, and the head diameter of the locking screw 56 is larger than the width of the waist-shaped hole 551. The locking screw 56 passes through the waist-shaped hole 551 and connects with the threaded hole 512, thereby fixing the moving block 52 and the fixed block 51. Specifically, when it is necessary to adjust the height of the hopper 1, the locking screw 56 is loosened, the adjusting screw 54 is rotated to drive the moving block 52 to slide along the fixed block 51, and after adjusting the hopper 1 to the required height position, the locking screw 56 is tightened. The limiting plate 55 is fastened to the side of the fixed block 51 by the locking screw 56, thereby fixing the moving block 52 and the fixed block 51.

[0030] The lower ends of the hopper 1 are inclined inward on both sides, such as Figure 2 As shown, the lower end of the hopper 1 is in the shape of a long funnel, which makes it easier for the particles to fall out of the discharge port 12.

[0031] The bottom of the cigarette gun front base plate assembly 6 is provided with several through holes 611 communicating with the feed guide groove 63. These through holes 611 can be used to connect an external negative pressure device to create negative pressure at the bottom of the feed guide groove 63, making the yarn more closely adhere to the inner wall of the feed guide groove 63. In this invention, the feed guide groove 63 is specifically a U-shaped groove. The cigarette gun front base plate assembly 6 specifically includes a front base plate body 61 and two baffles 62. The top of the front base plate body 61 is provided with an arc-shaped groove, and the two baffles 62 are located on both sides of the top of the front base plate body 61. The two baffles 62 and the arc-shaped groove together form the feed guide groove 63. The several through holes 611 are specifically provided at the bottom of the front base plate body 61.
