Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to an automatic cleaning mixing head device for chair back panels. Background Technology

[0002] After the existing pouring gun head completes the polyurethane foaming operation, hardened residue will be attached to its surface. The traditional cleaning method relies on manual scraping, which is not only inefficient but also labor-intensive. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide an automatic cleaning mixing head device for chair back panels, which not only does not rely on manual labor, but also improves work efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: an automatic cleaning mixing head device for chair back panels, comprising a base, a mounting plate disposed above the base, a blade head pivotally connected to the mounting plate, a screw connected to the blade head, and a nut seat fixed to the base and threadedly engaged with the screw; a plurality of guide posts are provided between the mounting plate and the base, the lower end of the guide posts is fixed to the base, the upper end of the guide posts is movably engaged with a guide sleeve on the mounting plate, a spring is sleeved on the guide posts, the lower end of the spring abuts against the base, and the upper end of the spring abuts against the mounting plate; the blade head includes a blade holder, a connecting post disposed at the bottom of the blade holder, and a plurality of blades fixed on the blade holder, the blade holder is provided with a receiving groove, and the blades are distributed around the receiving groove. The principle of this invention is as follows: When the casting gun head needs cleaning, the casting gun head is inserted downwards into the receiving groove of the cutter holder; the casting gun head presses down on the mounting plate, and the mounting plate moves downwards along the guide post and compresses the spring; during the downward movement of the mounting plate, the cutter head drives the screw, and because the screw is threadedly engaged with the nut seat, the screw rotates during the downward movement, and at the same time the screw drives the cutter head to rotate, and the blade on the cutter head rotates to cut the residue on the surface of the casting gun head; after cleaning, the casting gun head leaves the receiving groove, and the mounting plate moves upwards to reset under the force of the spring.

[0005] As an improvement, the tool holder includes a mounting plate and a plurality of mounting protrusions on the mounting plate. The mounting plate is provided with a limiting groove. One side of each mounting protrusion is provided with a mounting surface. The mounting surface is provided with a mounting hole. The bottom of the blade is located in the limiting groove. One side of the blade is in close contact with the mounting surface and is fixed to the mounting protrusion by bolts.

[0006] As an improvement, the connecting post is connected to the upper end of the screw via a connecting sleeve, the connecting post and the connecting sleeve are connected by a pin, and the screw and the connecting sleeve are connected by a pin.

[0007] As an improvement, the cutter head is pivotally connected to the mounting plate via a bearing housing. The bearing housing includes a first housing fixed on the mounting plate, a thrust cylindrical roller bearing disposed within the first housing, a second housing disposed at the bottom of the first housing, and a deep groove ball bearing disposed within the second housing. The cutter head presses against the thrust cylindrical roller bearing, and the connecting column passes through the deep groove ball bearing.

[0008] The beneficial effects of this utility model compared with the prior art are:

[0009] The mechanical adaptive adjustment significantly improves cleaning efficiency, making it particularly suitable for automated production lines. The screw and nut seat work together to make the cutter head rotate and cut under gravity. The spring and guide post work together to make the cutter head return to its original position under elastic force. No power is required, making it simple and efficient. Attached Figure Description

[0012] Figure 3 This is a schematic diagram of the tool holder. Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] like Figure 1 , 2 As shown, an automatic backrest cleaning mixing head device includes a base 9, a mounting plate 2 disposed above the base 9, a blade head 1 pivotally connected to the mounting plate 2, a screw 7 connected to the blade head 1, and a nut seat 8 fixed to the base 9 and threadedly engaged with the screw 7. Several guide posts 6 are provided between the mounting plate 2 and the base 9. In this embodiment, three circumferentially evenly distributed guide posts 6 are provided. The screw 7 is located in the middle of the three guide posts 6. The lower end of each guide post 6 is fixed to the base 9, and the upper end of each guide post 6 is movably engaged with a guide sleeve 4 on the mounting plate 2. A spring 5 is sleeved on each guide post 6. The lower end of the spring 5 abuts against the base 9, and the upper end of the spring 5 abuts against the mounting plate 2. The mounting plate 2 can sink along the guide post 6 and compress the spring 5. The blade head 1 includes a blade seat 11, a connecting post 12 disposed at the bottom of the blade seat 11, and several blades 13 fixed to the blade seat 11; as shown... Figure 3As shown, the cutter holder 11 is provided with a receiving groove 14, and the blades are distributed around the receiving groove 14. When the cutter head 1 rotates, the blades 13 can rotate and cut the casting gun head in the receiving groove 14. The cutter holder 11 includes a mounting plate and a number of mounting protrusions on the mounting plate. The mounting plate is provided with a limiting groove 111. One side of the mounting protrusion is provided with a mounting surface 112. The mounting surface 112 is provided with a mounting hole 113. The bottom of the blade 13 is located in the limiting groove 111. One side of the blade 13 is closely attached to the mounting surface 112 and fixed to the mounting protrusion by bolts. The position of the blade 13 can be adjusted and replaced. In this embodiment, there are a total of four blades 13 arranged in a cross shape. The connecting post 12 is connected to the upper end of the screw 7 through the connecting sleeve. The connecting post 12 and the connecting sleeve are connected by a pin. The screw 7 and the connecting sleeve are connected by a pin. The screw 7 transmits power to the cutter head 1 through the connecting sleeve. By removing the pin, the cutter head 1 can be separated from the screw 7. The cutter head 1 is pivotally connected to the mounting plate 2 via a bearing seat 3. The bearing seat 3 includes a first seat body 31 fixed on the mounting plate 2, a thrust cylindrical roller bearing 32 disposed in the first seat body 31, a second seat body 33 disposed at the bottom of the first seat body 31, and a deep groove ball bearing 34 disposed in the second seat body 33. The cutter head 11 presses against the thrust cylindrical roller bearing 32, and the connecting column 12 passes through the deep groove ball bearing 34. The thrust cylindrical roller bearing bears the axial cutting force, and the deep groove ball bearing suppresses radial vibration, ensuring the motion stability of the cutter head 1 on the curved surface of the gun head.

[0015] The principle of this invention is as follows: When the casting gun head needs cleaning, the casting gun head is inserted downward into the receiving groove 14 of the cutter holder; the casting gun head presses down on the mounting plate 2, and the mounting plate 2 moves downward along the guide post 6 and compresses the spring 5; during the downward movement of the mounting plate 2, the cutter head 1 drives the screw 7. Since the screw 7 is threadedly engaged with the nut seat 8, the screw 7 rotates during the downward movement. At the same time, the screw 7 drives the cutter head 1 to rotate, and the blade on the cutter head 1 rotates to cut the residue on the surface of the casting gun head; after cleaning, the casting gun head leaves the receiving groove 14, and the mounting plate 2 moves upward and resets under the force of the spring 5.
