Technical Field

[0001] The utility model relates to the technical field of sand producing equipment, in particular to a quantitative sand producing cylinder. Background Art

[0002] Asphalt shingles (also known as fiberglass shingles, asphalt shingles, fiberglass asphalt shingles) are new waterproof building materials and also a new type of roofing material used for building roof waterproofing. They are mainly suitable for roofs of any shape with a slope of 5-90 degrees and spherical roofs. There is an important process in the production line of asphalt shingles, which is the processing of the colored sand decorative layer of asphalt shingles. Whether the color arrangement of the decorative layer of asphalt shingles is uniform, reasonable and beautiful affects the overall visual effect of asphalt shingles, and therefore determines whether they are favored by consumers.

[0003] Prior art, such as the utility model patent document with authorization announcement number "CN218872716U" and patent name "A kind of anti-clogging non-asphalt-based waterproof membrane sand coating machine", discloses a sand discharge device, which is composed of a frame, a sand collecting bucket, a receiving roller, a swing mechanism and a sand pressing part. A receiving roller is installed on the frame below the sand collecting bucket, and a slow-flow roller is installed on the sand collecting bucket corresponding to the receiving roller through an assembly plate. A sand outlet is provided on the sand collecting bucket corresponding to the slow-flow roller, and a swing mechanism is installed on the sand collecting bucket at the rear end of the sand outlet, and a sand pressing part is provided on the frame on one side of the receiving roller.

[0004] However, in actual use of the above patent, sand flows out from the sand collecting hopper through the sand outlet, so the device is only provided with a component for controlling the on-off of the discharge pipe, so that the amount of sand blasting during use is fixed, resulting in the inability to adjust and change the discharge amount of sand according to actual requirements. However, the amount of sand often needs to be changed on the production line for combined proportioning, so it is necessary to set up a discharge device that can quantitatively discharge sand. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a quantitative sand discharge cylinder, which is used to solve the technical problem that some sand discharge cylinders mentioned in the background technology are only provided with components for controlling the on-off of the discharge pipe, so that the sand blasting amount during use is fixed, resulting in the sand discharge amount cannot be adjusted and changed according to actual requirements.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A quantitative sand discharge cylinder comprises a sand discharge cylinder body with openings on both the upper and lower sides and a conveyor arranged below the sand discharge cylinder body, a supporting plate is arranged below the sand discharge cylinder body, an arc-shaped sand discharge hole is opened on the supporting plate, a rotatable annular disk is arranged on the side of the supporting plate facing the conveyor, a plurality of through holes are spaced apart on the annular disk and penetrate the annular disk up and down, and the sizes of the plurality of through holes in the clockwise direction increase or decrease in sequence, and the conveyor is used to transport sand that falls from the sand discharge cylinder body through the arc-shaped sand discharge hole and the through hole.

[0008] Working principle:

[0009] When in use, sand flows downward from the sand discharge tube body and flows out through the supporting plate; at this time, the annular disk is rotated, and the sand flowing out of the supporting plate flows out through the arc-shaped sand discharge holes and the through holes, and then the fallen sand is transported by the conveyor.

[0010] Beneficial effects:

[0011] In this solution, by setting a rotating arc-shaped sand outlet hole, annular disk and through holes, the sand falling from the supporting plate passes through the rotating annular disk and flows out from the through holes opened on the annular disk and distributed in a clockwise direction and increasing or decreasing in sequence. Therefore, the amount of sand falling on the conveyor can be adjusted to adapt to the amount and ratio of sand required on the production line. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0018] Example:

[0019] like Figure 1 to Figure 3 As shown, a quantitative sand discharger comprises a sand discharger body 1 with openings on both the upper and lower sides and a conveyor 2 arranged below the sand discharger body 1, a supporting plate 3 is arranged below the sand discharger body 1, an arc-shaped sand discharge hole 4 is opened on the supporting plate 3, a rotatable annular disk 5 is arranged on the side of the supporting plate 3 facing the conveyor 2, a plurality of through holes 6 penetrating the annular disk 5 are spaced apart on the annular disk 5, and the sizes of the plurality of through holes 6 along the clockwise direction increase successively, and the conveyor 2 is used for transporting sand that falls from the sand discharger body 1 through the arc-shaped sand discharge hole 4 and the through hole 6. In this solution, by setting a rotating arc-shaped sand outlet hole 4, an annular disk 5 and a through hole 6, the sand falling from the supporting plate 3 passes through the rotating annular disk 5 and flows out from the through holes 6 opened on the annular disk 5 and distributed and increasing in a clockwise direction. Therefore, the amount of sand falling on the conveyor 2 can be adjusted to adapt to the amount and ratio of sand required on the production line.

[0020] like Figure 1 to Figure 3 As shown, two arc-shaped slide rails 7 are provided at the bottom of the support plate 3, and the annular disk 5 is slidably arranged in the two arc-shaped slide rails 7. A circle of racks 8 are provided on the outer circumference of the annular disk 5, and a motor 9 is provided on one side of the conveyor 2. The output end of the motor 9 is vertically upward and connected to a transmission shaft 10. A gear 11 is fixed on the top of the transmission shaft 10, and the gear 11 is meshed with the rack 8. By providing the arc-shaped slide rail 7, rack 8, motor 9, transmission shaft 10 and gear 11, the motor 9 is started to drive the annular disk 5 to rotate, so that the size of the through hole 6 from which the sand flows out can be controlled, thereby changing the discharge amount of the sand material.

[0021] like Figure 1 to Figure 3 As shown, the cross-section of the two arc-shaped slide rails 7 is C-shaped, and an annular slider 19 is fixedly provided on the outer bottom wall and the inner bottom wall of the circular ring disk 5. The slider 19 is slidably arranged in the arc-shaped slide rail 7. The slider 19 is "L"-shaped, and one end of one of the sliders 19 is fixedly connected to the outer bottom wall of the circular ring disk 5, and the other end is in contact with the side wall of one of the arc-shaped slide rails 7; one end of the other slider 19 is fixedly connected to the inner bottom wall of the circular ring disk 5, and the other end is in contact with the side wall of the other arc-shaped slide rail 7; the rack 8 does not contact the side wall of the arc-shaped slide rail 7. By providing the slider 19, it is possible to prevent the rack 8 from contacting the inner wall of the arc-shaped slide rail 7, thereby affecting the normal rotation of the circular ring disk 5.

[0022] like Figure 1As shown, a first mounting plate 12 is provided at the lower end of the sand discharge tube body 1, a second mounting plate 13 is fixed below the first mounting plate 12, and a material drop hole is provided on both the first mounting plate 12 and the second mounting plate 13, and a gap is provided between the first mounting plate 12 and the second mounting plate 13, in which a sand retaining plate 14 is slidably provided; a connecting tube 18 is fixed at the lower end of the second mounting plate 13, and the supporting plate 3 is fixed at the lower end of the connecting tube 18. By providing the first mounting plate 12, the second mounting plate 13, the sand retaining plate 14 and the connecting tube 18, the sand flowing out of the sand discharge tube body 1 falls onto the conveyor 2 in the order of the material drop holes, the connecting tube 18, the supporting plate 3 and the annular disk 5 on the first mounting plate 12 and the second mounting plate 13; by providing the sand retaining plate 14, the passage between the sand discharge tube body 1 and the connecting tube 18 can be blocked to control the falling of the sand.

[0023] like Figure 1 As shown, the sand retaining plate 14 is divided into two parts: a blocking portion 141 and a sand passing portion 142. A first limit block 23 is provided at one end of the blocking portion 141 away from the sand passing portion 142, and a second limit block 22 is provided at one end of the sand passing portion 142 away from the blocking portion 141; a cylinder 17 is provided on one side of the sand discharge tube body 1, and the telescopic end of the cylinder 17 is fixedly connected to the first limit block 23. The blocking portion 141 is a fully enclosed panel, and the sand passing portion 142 is a panel with a blanking hole in the middle.

[0024] like Figure 1 As shown, by setting the first limit block 23, the second limit block 22 and the cylinder 17, the cylinder 17 is started to drive the sand baffle 14 to move between the first mounting plate 12 and the second mounting plate 13. When the blocking portion 141 is arranged between the first mounting plate 12 and the second mounting plate 13, the passage between the sand discharge tube body 1 and the connecting tube 18 is blocked and is in a closed state. At this time, the sand cannot pass through the blanking holes on the first mounting plate 12 and the second mounting plate 13; when the sand passing portion 142 is arranged between the first mounting plate 12 and the second mounting plate 13, the passage between the sand discharge tube body 1 and the connecting tube 18 is opened. At this time, the sand continues to fall down through the blanking holes on the first mounting plate 12 and the second mounting plate 13, so as to control the falling of the sand; the first limit block 23 and the second limit block 22 can limit the position of the blocking portion 141 and the sand passing portion 142 to prevent the cylinder 17 from over-expanding and extending, so that the first limit block 23 and the second limit block 22 are separated from the gap between the first mounting plate 12 and the second mounting plate 13.

[0025] like Figure 1As shown, the four corners of the first mounting plate 12 are all threadedly connected with second bolts 15, and the second bolts 15 pass through the first mounting plate 12 and the second mounting plate 13 and the three are threadedly connected. By providing the second bolts 15, the first mounting plate 12 and the second mounting plate 13 can be disassembled, which is convenient for subsequent maintenance.

[0026] Working principle:

[0027] When in use, start the transporter 2;

[0028] Then, the cylinder 17 is started, and the telescopic end of the cylinder 17 pulls the sand retaining plate 14, so that the sand passing portion 142 is arranged between the first mounting plate 12 and the second mounting plate 13. At this time, a passage is formed between the sand discharge tube body 1 and the connecting tube 18; at the same time, the motor 9 is started, and the output end of the motor 9 drives the transmission shaft 10 to rotate, and the rotation of the transmission shaft 10 drives the gear 11 to rotate, and the rotation of the gear 11 drives the rack 8 to rotate, and the rotation of the rack 8 drives the annular disk 5 to rotate;

[0029] Then the sand flowing out of the sand discharge tube body 11 falls onto the conveyor 2 in the order of the drop hole of the first mounting plate 12, the sand passing portion 142 of the sand retaining plate 14, the drop hole on the second mounting plate 13, the connecting tube 18, the supporting plate 3 and the arc-shaped sand discharge hole 4, and the sand is transported by the conveyor 2, and the whole operation is completed.

[0030] 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 field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
