DETAILED DESCRIPTION

[0026] The technical scheme of the utility model will be further described below with reference to the drawings.

[0027] Embodiment 1: as Figures 1 to 3 The utility model discloses filter shell conveying device mainly by hopper 5, first conveyor belt 4 is composed, and first conveyor belt 4 is used to drive over half shell to ascend to preset height: the even several brackets 41 of conveyor belt are equipped, and bracket 41 holds half shell from below, so that half shell can climb with first conveyor belt 4.Hopper 5 is used to store half shell, and the bottom of hopper 5 is discharge port, and discharge port is located above the upper surface of first conveyor belt 4, and through the gravity effect, half shell in hopper 5 can fall, shift to first conveyor belt 4;The left and right sides of the discharge port of hopper 5 are connected with the left and right sides of first conveyor belt 4, form left and right baffle, prevent the material from being bounced off first conveyor belt 4 in the process that half shell shifts to first conveyor belt 4, and the inner wall of left and right sides of hopper 5 is inclined, and is gathered towards the left and right sides of first conveyor belt 4, forms the funnel shape, so that half shell originally located in the corner of hopper 5 is gathered towards first conveyor belt 4.

[0028] Hopper 5 has upper and lower side walls, and the upper and lower side walls can be inclined surfaces or straight surfaces, the notch 51 is provided at the bottom of the upper and lower side walls and connected with the left and right sides of the first conveyor belt 4, and the notch 51 and the upper surface of the first conveyor belt 4 form a limit; the height of the top of the notch 51 from the upper surface of the first conveyor belt 4 is greater than the maximum height H1 of a single half shell in a flat state and less than the maximum height 2H1 of two half shells in a stacked state, so as to ensure that a single half shell is sequentially conveyed by the first conveyor belt 4 during discharging, and avoid stacking of materials on the first conveyor belt 4. The inner side of the lower side wall of the hopper 5 is rotatably connected with the push plate 52, the push plate 52 is driven by the intermittent drive mechanism 6, so as to avoid material jamming, and the drive mechanism 6 can be a motor or an air cylinder.

[0029] The bracket 41 is comb-shaped, and when the first conveying belt 4 is driven to move away from the hopper 5, the first conveying belt 4 and the gap 51 can be blocked. The comb-shaped structure allows the bracket 41 to have a certain deformation amount, thereby reducing the blocking.

[0030] In the embodiment 2, on the basis of the embodiment 1, the height of the gap 51 in the upper side wall of the hopper 5 is not limited, and a stack prevention mechanism is arranged on the top of the first conveying belt 4 or on the first conveying belt 4 above the hopper 5.

[0031] As shown in Figure 4 , the stack prevention mechanism comprises a second conveying belt 1, a rejection mechanism 2 and a recycling channel 3. The rejection mechanism 2 and the recycling channel 3 are located on opposite sides of the second conveying belt 1. The distance H3 (for reference Figure 8 ) between the output end 21 of the rejection mechanism 2 and the upper surface of the second conveying belt 1 is greater than the maximum height H1 of a single half-shell in a flat state. The recycling channel 3 is connected to the hopper 5. When the half-shells are stacked, the stacked filter shells exceeding the preset height are pushed away by the force of the rejection mechanism 2 and are collected by the recycling channel 3 and returned to the hopper 5 for re-feeding. The hopper 5 and the recycling channel 3 are connected by a slide 32. The half-shells rejected by the rejection mechanism 2 are recycled to the hopper 5 by the slide 32.

[0032] In the embodiment, the rejection mechanism 2 can be a telescopic rod or a guide rail with a guide structure. The height of the guide rail from the upper surface of the second conveying belt 1 is greater than the maximum height H1 of a single filter shell in a flat state and less than 2H1, the maximum thickness of two stacked filter shells.

[0033] In the embodiment 3, on the basis of the embodiments 1 and 2, the top height of the gap 51 is limited to ensure that the first conveying belt 4 conveys a single filter shell each time. The distance H3 (for reference Figure 8 ) between the output end 21 of the rejection mechanism 2 and the upper surface of the second conveying belt 1 is limited to the maximum height H1 of a single half-shell in a flat state. In the embodiment, the second conveying belt 1 can further have the following variations: a front and back face screening function of the half-shell is added to the second conveying belt 1.

[0034] As shown in Figures 5 to 7 , a plurality of protrusions 11 are arranged on the belt of the second conveying belt 1. The protrusions 11 distinguish the front and back faces of the filter half-shell. The protrusions 11 distinguish the front and back faces of the half-shell in combination with the structure of the filter shell. The structure of the filter shell is described as follows: Figure 9The filter housing comprises top and bottom half shells 100, which are similar in structure and each has a circular cover surface 102 and a circular annular opening 103, the outer diameter of the opening 103 being smaller than that of the cover surface 102, wherein the depth of the opening 103 of the top half shell 100 is smaller than that of the bottom half shell, and when assembled, the opening 103 of the top half shell is sleeved into the opening of the bottom half shell, and then the whole is formed by welding or other connection methods. The protrusions 11 distinguish the front and back of the half shells 100 as follows: the half shell is placed with the opening 103 facing down to be defined as the front, and the half shell is placed with the opening 103 facing up to be defined as the back. Figure 7 The distance L between two adjacent protrusions 11 is smaller than the outer diameter D of the cover surface 102 of the half shell, and the half shell 100 placed with the opening 103 facing up cannot be placed flat on the second conveying belt 1 and will be lifted by the protrusions 11, cannot pass under the rejection mechanism 2, and can only be rejected; the height H4 of the protrusion 11 is not greater than the depth H0 of the opening 103 of the half shell 100, and the opening 103 of the half shell 100 placed with the opening 103 facing up can cover the protrusion 11 and will not be lifted by the protrusion 11, and when the half shell is subjected to the force of the rejection mechanism 2, it can be hooked by the protrusion 11 to resist the force of the rejection mechanism 2 or directly pass under the rejection mechanism 2 and cannot leave the second conveying belt 1. The protrusions 11 are cylindrical and made of elastic materials such as rubber and silicone, which can reduce the damage to the half shells caused by bumps during conveying.

[0035] As shown in Figure 9 , a conduit 104 is connected to the cover surface 102 of the half shell, the conduit 104 and the opening 103 are located on the upper and lower sides of the cover surface 102 respectively, the conduit 104 is arranged radially along the cover surface 102 and protrudes outward by a portion relative to the cover surface 102 to form a ridge, if the conduit 104 of the half shell is located in front of the half shell (towards the conveying direction consistent with the second conveying belt 1), the cover surface 102 is lifted by the protrusion 11 located in front, and the conduit 104 is located between the protrusion 11 and the rejection mechanism 2, and the other end of the cover surface 102 opposite to the conduit 104 falls on the upper surface of the second conveying belt 1 and abuts against the root of the protrusion 11 behind the half shell 100, in this case, the conduit 104 on the front side of the half shell 100 and the protrusion 11 in front approximately form a hook (or are blocked by the protrusion 11 in front), the protrusion 11 behind is elastic and abuts against the cover surface after deformation, and the double constraint causes the half shell 100 to be unable to be rejected by the rejection mechanism 2 and enters the downstream with the second conveying belt 1, affecting the screening accuracy, therefore, as shown in Figure 6 , a bevel 111 is arranged on one side of the protrusion 11 to reduce the contact area between the protrusion 11 behind the half shell 100 and the edge 101 of the half shell 100, reduce the constraint of the half shell 100, and solve the problem that the half shell 100 placed with the opening 103 facing up cannot be rejected, the bevel 111 is consistent with the conveying direction of the second conveying belt 1, for example, in the right direction, if the second conveying belt 1 moves to the right to convey the half shell, the bevel 111 of the protrusion on the upper surface of the second conveying belt 1 is located on the right side of the protrusion 11. Figure 6 ​

[0036] With the inner diameter d of the open 103 of the half shell, the radius r of the protrusion 11 as reference, the distance L between the two adjacent protrusions 11 and the inner diameter d of the open 103 of the half shell satisfy L + 2r < d, if the distance L between the two adjacent protrusions 11 and the inner diameter d of the open 103 are close, i.e. L + 2r ≥ d but less than the outer diameter D of the cover surface 102 of the half shell, when the half shell is placed in the front surface, the open 103 of the half shell is lifted by the two adjacent protrusions 11, the height of the half shell placed in the front surface is increased, and the half shell is wrongly rejected.

[0037] In this embodiment, the rejection mechanism 2 is a wind knife, which can save other detection mechanisms and avoid the half shell placed in the back surface being forced to leave the protrusion 11 but not leaving the second conveying belt 1 in time, and falling back to the second conveying belt 1, resulting in screening failure. The rejection mechanism 2 can ensure the pushing speed and reduce the contact pollution of the half shell in the conveying process of the filter housing. When the rejection mechanism 2 is a wind knife, if the airflow direction of the wind knife is towards the second conveying belt 1, the airflow diverted by the second conveying belt 1 will affect the half shell 100 placed in the front surface through the edge 101 of the cover surface 102 of the half shell, affecting the screening accuracy. Therefore, the air curtain formed by the airflow blown out of the output end of the wind knife is preferably parallel to the upper surface of the second conveying belt 1, and correspondingly, the recovery channel 3 is provided with an air outlet hole 31 to minimize the influence of the airflow on other half shells conveyed on the second conveying belt 1.

[0038] As shown in Figure 5 , the second conveying belt 1 is provided with a guide mechanism 7 on one side, and the guide mechanism 7 and the rejection mechanism 2 are located on the same side, so that the half shell 100 on the second conveying belt 1 is pushed away from the rejection mechanism 2: if the half shell 100 is placed in the front surface, after passing through the guide mechanism 7, the inner wall of the open 103 of the half shell and the protrusion 11 are in contact, ensuring the hooking effectiveness, if the half shell is placed in the back surface, the half shell is lifted by the protrusion 11, after passing through the guide mechanism 7, the opening angle between the half shell and the upper surface of the second conveying belt 1 is formed towards the rejection mechanism 2, which is easy to be pushed away from the second conveying belt 1 by the rejection mechanism 2. In order to reduce friction, the guide mechanism 7 is a roller, and the bottom of the guide mechanism 7 and the side edge support of the second conveying belt 1 are slidingly connected, so as to facilitate the adjustment of the position of the guide mechanism 7.
