Description

Technical Field

[0001] This utility model relates to the field of asphalt shingle technology, and in particular to an auxiliary material addition switch. Background Technology

[0002] Asphalt shingles are a new type of roofing material used for waterproofing building roofs.

[0003] In the processing of asphalt shingles, raw materials need to be placed in equipment and then calcined. During calcination, the equipment needs to be sealed. Therefore, a switch door needs to be designed to facilitate user operation, allowing for the addition of raw materials and the sealing of the equipment for calcination. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an auxiliary material adding switch door, which solves the technical problem that the opening and closing of the switch door in some existing equipment is cumbersome and affects the processing efficiency of asphalt shingles.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A material adding switch door includes a housing with a feeding port extending through it. A connecting shaft is rotatably mounted on the inner wall of the housing. A door panel for closing the feeding port is fixed on the connecting shaft. A first connecting rod is fixed to one end of the connecting shaft extending out of the housing. A second connecting rod is rotatably mounted at the end of the first connecting rod. A handle is fixed to the end of the second connecting rod. A first abutment plate and a second abutment plate are fixed to one end of the housing. When the handle contacts the first abutment plate, the door panel closes the feeding port. When the handle contacts the second abutment plate, the door panel opens.

[0007] Working principle:

[0008] When raw materials need to be added to the chamber for calcination, the user rotates the second connecting rod around the first connecting rod using the handle. After rotating the second connecting rod 160 to 180 degrees, the user moves the second connecting rod using the handle. The second connecting rod then rotates the first connecting rod around the connecting shaft axis. The first connecting rod then rotates the connecting shaft, which in turn rotates the door panel. After the door panel rotates, the feeding port opens. The user then rests the handle against one end of the second abutment plate, preventing the door panel from closing the feeding port. The user adds raw materials to the chamber through the feeding port. After adding the raw materials, the user rotates the door panel again using the handle, rotating the second connecting rod so that the handle rests against the first abutment plate, and the door panel closes the feeding port.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] 1. By abutting the handle against the first abutting plate, the door panel cannot be rotated, thus sealing the feeding port. During calcination, the door panel cannot be opened, ensuring the user's safety.

[0011] 2. By rotating the second connecting rod around the first connecting rod with the handle, and then pushing the first connecting rod to rotate, the handle abuts against the second abutment plate, so that the door panel cannot be reset after rotation, and the feeding port is in the open state, making it convenient for the user to add raw materials into the box through the feeding port.

Detailed Implementation

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0019] Example:

[0020] like Figure 2 and Figure 3As shown, an auxiliary material adding switch door includes a housing 10 with a feeding port 20 extending through it. A connecting shaft 18 is rotatably mounted on the inner wall of the housing 10. A door panel 14 for closing the feeding port 20 is fixed on the connecting shaft 18. A first connecting rod 24 is fixed at one end of the connecting shaft 18 extending out of the housing 10. A second connecting rod 29 is rotatably mounted at the end of the first connecting rod 24. A handle 28 is fixed at the end of the second connecting rod 29. A first abutting plate 27 and a second abutting plate 30 are fixed at one end of the housing 10. One end of the second abutting plate 30 has two opposing inclined surfaces. After the handle 28 rotates, it is engaged between the two inclined surfaces. When the handle 28 contacts the first abutting plate 27, the door panel 14 closes the feeding port 20. When the handle 28 contacts the second abutting plate 30, the door panel 14 opens.

[0021] When raw materials need to be added to the chamber 10 for calcination, the user drives the second connecting rod 29 to rotate around the first connecting rod 24 via the handle 28. The user rotates the second connecting rod 29 160 to 180 degrees; this rotation angle is only to facilitate the user's force to rotate the first connecting rod 24, and the user can adjust it according to the actual situation. The user moves the second connecting rod 29 via the handle 28, which in turn drives the first connecting rod 24 to rotate around the axis of the connecting shaft 18. The first connecting rod 24 drives the connecting shaft 18 to rotate, which in turn drives the door panel 14 to rotate. After the door panel 14 rotates, the feeding port 20 opens. By placing the handle 28 against one end of the second abutment plate 30, the door panel 14 cannot close the feeding port 20. The user then... Raw materials are added into the box 10 through the feeding port 20. After the addition is completed, the door panel 14 is rotated by the handle 28, and the second connecting rod 29 is rotated so that the handle 28 rests against the first abutment plate 27. The door panel 14 closes the feeding port 20. The door panel 14 cannot be rotated by the abutment of the handle 28 against the first abutment plate 27. That is, the door panel 14 closes the feeding port 20. During calcination, the door panel 14 cannot be opened, ensuring the safety of the user. After the second connecting rod 29 is rotated around the first connecting rod 24 by the handle 28, the first connecting rod 24 is pushed to rotate. The handle 28 abuts against the second abutment plate 30, so that the door panel 14 cannot be reset after rotation. The feeding port 20 is in the open state, which makes it convenient for the user to add raw materials into the box 10 through the feeding port 20.

[0022] like Figure 2 , Figure 3 and Figure 5As shown, a contact plate 19 is fixedly installed on a section of the connecting shaft 18 inside the housing 10. A connecting block 17 is fixedly installed on one end of the contact plate 19. The door panel 14 is fixedly installed on one end of the connecting block 17. A third connecting rod 23 is fixedly installed on one end of the connecting shaft 18 extending out of the housing 10. A first connecting rod 24 is fixedly installed on one end of the third connecting rod 23. A limiting sleeve is fixedly installed at the end of the first connecting rod 24. A second connecting rod 29 is rotatably mounted on the limiting sleeve. The limiting sleeve includes two limiting pieces 25 and a limiting post 34. The two limiting pieces 25 are respectively fixed at both ends of the limiting post 34. One of the limiting pieces 25 is fixed at the end of the first connecting rod 24. A sleeve 26 is rotatably mounted on the outer circumference of the limiting post 34. The second connecting rod 29 is fixed on the sleeve 26.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, two horizontal placement columns 12 are fixedly installed at one end of the door panel 14. A storage cavity 11 is horizontally opened through each placement column 12. Two blocking blocks 13 are slidably installed along the length of each storage cavity 11. After extending out of the storage cavity 11, the two blocking blocks 13 abut against the box body 10. When the blocking blocks 13 move, the door panel 14 cannot rotate into the box body 10. A first force-bearing shaft 21 is rotatably installed within each storage cavity 11. A connecting piece 33 is fixedly installed on the first force-bearing shaft 21, and two second force-bearing shafts are rotatably installed on the connecting piece 33. A fourth connecting rod 32 is rotatably mounted on the second force-bearing shaft 31. A third force-bearing shaft 16 is rotatably mounted at the end of the fourth connecting rod 32. A fifth connecting rod 15 is rotatably mounted on the third force-bearing shaft 16. The fifth connecting rod 15 is fixedly connected to the corresponding blocking block 13. A force-bearing plate 22 is fixedly mounted at one end of the first force-bearing shaft 21 that extends out of the storage cavity 11. The force-bearing plate 22 facilitates the user to rotate the first force-bearing shaft 21, thereby driving the blocking block 13 to move. When it is necessary to calcine the raw material for a long time, the blocking block 13 is moved to restrict the rotation of the door panel 14.

[0024] Working principle:

[0025] When it is necessary to open the door panel 14 and put raw materials into the box 10, the user drives the second connecting rod 29 to rotate around the first connecting rod 24 through the handle 28. After rotating to a certain angle, the second connecting rod 29 drives the first connecting rod 24 to rotate around the axis of the connecting shaft 18. The first connecting rod 24 drives the connecting shaft 18 to rotate. The connecting shaft 18 drives the connecting block 17 to rotate through the contact plate 19. The connecting block 17 drives the door panel 14 to rotate. After the rotation is completed, the handle 28 is engaged with one end of the second abutment plate 30, and raw materials are added into the box 10 through the feeding port 20.

[0026] When the material addition is completed and the door panel 14 needs to be closed, the first connecting rod 24 is driven to rotate around the axis of the connecting shaft 18 by the second connecting rod 29. The first connecting rod 24 drives the connecting shaft 18 to rotate. The connecting shaft 18 drives the connecting block 17 to rotate through the contact plate 19. The connecting block 17 drives the door panel 14 to rotate. The door panel 14 closes the feeding port 20, and the handle 28 is engaged with one end of the first abutment plate 27.

[0027] When the feeding port 20 needs to be closed for a long time, rotate the force plate 22. The force plate 22 drives the connecting piece 33 to rotate through the first force shaft 21. The connecting piece 33 drives the fourth connecting rod 32 to move through the second force shaft 31. The fourth connecting rod 32 drives the fifth connecting rod 15 to move through the third force shaft 16. The fifth connecting rod 15 drives the blocking block 13 to move. After the blocking block 13 moves, it abuts against the end face of the box 10 to prevent the door panel 14 from being opened by accident.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
