Description

Technical Field

[0001] This invention relates to the field of quartz processing technology, and more specifically, to a method for splicing and reusing quartz scraps. Background Technology

[0002] Currently, the processing of quartz products generates a lot of scrap material. To reduce costs, this scrap material is often utilized, as disclosed in Chinese Patent Application No. 2022107544966, which describes a method for recycling quartz tubes. The common approach now is to weld several pieces of scrap material together to form a single piece, and then machine the entire piece. However, because the scrap materials vary in shape, welding them together before machining results in low material utilization and a large workload for welding. Summary of the Invention

[0003] To overcome the above shortcomings, the present invention provides a method for splicing and reusing quartz scraps, which can achieve splicing and reuse of quartz scraps, with high material utilization, good connection effect at the splicing point, and eliminates the problems of bubbles and air lines caused by welding.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a method for splicing and reusing quartz scraps, comprising the following steps: S1, cutting the scraps into splicing strips; S2, splicing the splicing strips, heating and melting the splicing joint, pushing the splicing strips to squeeze the molten joint, and cooling to achieve the connection of the splicing strips; S3, repeating S2 until the desired product shape is spliced.

[0005] Quartz scraps are cut into splicing strips to form part of the desired quartz product shape. When joining the splicing strips, the joint is heated and melted, and the strip is moved to compress the molten area, ensuring the molten material fills the joint and forms a single unit between adjacent strips. After cooling, the strips are joined. Multiple splicing strips are joined to form the desired product, achieving the reuse of quartz scraps.

[0006] The technical solution of this patent application realizes the recycling of quartz scraps and processes quartz products by splicing. The material utilization rate is high, and the splicing is squeezed to make the splicing effect good, which can eliminate the defects of bubbles and air lines caused by welding.

[0007] As a preferred option, in step S1, lines are drawn on the scrap material according to the shape of the product to be assembled, and the material is cut according to the lines.

[0008] First, draw lines on the scrap material, then cut according to the lines to ensure cutting accuracy.

[0009] In another approach, during step S1, scrap materials are loaded onto the worktable. The shape and outline of the product to be assembled are projected onto the worktable and scrap materials using light. The position of the scrap materials is adjusted so that they can fully receive the light projection. Laser cutting is then performed along the light projection outline on the scrap materials.

[0010] The shape of the quartz product to be processed is projected onto the worktable using light projection. The position of the scrap material on the worktable is then adjusted to ensure that as much of the scrap area as possible is projected onto the outline of the light rays, thereby improving the utilization rate of the scrap material. Laser cutting is then performed along the projected outline on the scrap material, ensuring precision and reliability.

[0011] Preferably, in step S1, the ends of the splicing strip are trimmed, with one end of the splicing strip having a planar structure and the other end having chamfered edges on both sides to form a trapezoidal structure.

[0012] After trimming, during the splicing process of the splicing strips, the edge of the planar structure of one splicing strip aligns with the edge of the trapezoidal structure of another splicing strip. During the heating and melting process, the heated area is increased, and the chamfer provides a space for accommodating the material. The molten material fills the chamfer, improving the connection strength of the splicing strips.

[0013] Preferably, when two adjacent splicing strips in S2 are heated and melted, one splicing strip is pressed and fixed, and a pushing force is applied to the other splicing strip, thereby squeezing the molten area.

[0014] One splicing strip is pressed and fixed to achieve reliable positioning. A thrust is applied to the other splicing strip, which compresses the molten area, filling the splice with molten quartz material, preventing voids and ensuring the reliability of the splice.

[0015] As a preferred option, the splicing strips are in the form of a fan-shaped ring structure, and multiple splicing strips are spliced ​​together to form a ring-shaped quartz product.

[0016] Quartz scraps are processed into fan-shaped rings, and multiple fan-shaped rings are spliced ​​together to form a ring-shaped quartz product, thus completing the processing from scraps to quartz rings and realizing the secondary utilization of scraps.

[0017] Preferably, the splice strip is positioned on the loading platform, which is provided with a positioning ring groove. A pressure block and a one-way rotating buffer arm are installed on the loading platform, and a buffer column is installed on the buffer arm. The splice strip is loaded in the positioning ring groove, the pressure block presses on the upper part of one splice strip for positioning, and the top of the buffer column provides a squeezing thrust at the end of another adjacent splice strip.

[0018] The positioning ring groove is adapted to the fan-shaped splicing strip. During the splicing operation, the splicing strip is loaded into the positioning ring groove to achieve radial positioning. A pressure block presses down on the top of one splicing strip for positioning, while a buffer column provides a squeezing thrust at the end of another adjacent splicing strip. This achieves clamping and positioning of the two splicing strips. After the splicing joint of the two strips is heated and melted, the buffer column pushes the splicing strip towards the joint, squeezing out the molten quartz and filling the joint to prevent voids. After the two splicing strips are connected, they are rotated, and the lowered splicing strip is then loaded into the positioning ring groove for the next splicing operation, until a quartz ring is formed. When splicing the last section of the splicing strip, first cut the splicing strip to a suitable length. The length of the splicing strip is slightly larger than the circumferential length of the last gap of the quartz ring. Generally, both ends of the splicing strip are 1-3mm longer. Then, heat and melt both ends of the splicing strip. At this time, the buffer column is removed, and the buffer arm is pressed on the splicing strip. After both ends of the splicing strip are melted, the splicing strip is pressed down into the positioning ring groove. Continue heating until both ends of the splicing strip are spliced.

[0019] Preferably, a mounting column is provided on the loading platform, and a lifting and moving mounting sleeve is mounted on the mounting column. An adjusting sleeve is mounted on the outside of the mounting sleeve. A ratchet mechanism is installed between the inner wall of the adjusting sleeve and the outer wall of the mounting sleeve to realize the unidirectional rotation of the adjusting sleeve. A buffer arm is fixedly connected to the adjusting sleeve.

[0020] The splicing strips cut from scrap materials are of varying lengths. The adjusting sleeve is rotated to accommodate these different lengths. The buffer arm rotates unidirectionally with the adjusting sleeve. During rotation, the position of the buffer post is adjusted. Once in place, the buffer post rests against the end of the splicing strip, at which point the buffer arm locks in the reverse direction, ensuring the buffer post provides reliable cushioning thrust to the splicing strip. Furthermore, the mounting sleeve can be raised and lowered; when adjusting the position, the mounting sleeve can be lifted to prevent interference.

[0021] Another option is to use rectangular splicing strips, with multiple splicing strips joined together to form a long strip of quartz product.

[0022] Quartz scraps are cut into rectangular structures, and multiple splicing strips are then joined together to form rectangular quartz products, thus realizing the secondary use of quartz scraps.

[0023] Preferably, the splicing strip is positioned on a positioning platform. The positioning platform is provided with a long strip-shaped positioning groove, and a slot is provided on the side wall of the positioning groove. A buffer positioning block with lifting and a sliding end positioning block are installed on the positioning platform. The splicing strip is loaded in the positioning groove, and both ends of the splicing strip are inserted into the slot. The end positioning block abuts against the end of one splicing strip, and the buffer positioning block abuts against the end of another adjacent splicing strip to provide extrusion thrust.

[0024] The two ends of the splicing strip are locked in the slots to achieve vertical positioning. After the two splicing strips to be spliced ​​are installed into the positioning slots, the end positioning block presses against the end of one splicing strip, and the buffer positioning block abuts against the end of another adjacent splicing strip to provide extrusion thrust. During the heating and melting process, the splicing is completed by extrusion at the splicing point.

[0025] Compared with the prior art, the beneficial effects of the present invention are: (1) Quartz scraps are cut and then spliced ​​to achieve secondary utilization. Quartz products are processed by splicing, resulting in high material utilization. The splicing joint is melted and squeezed, resulting in good connection effect and eliminating the problems of bubbles and air lines caused by welding; (2) The shape of the quartz product to be processed is projected onto the worktable by light projection. At this time, the position of the scraps on the worktable is adjusted so that as much of the scrap area as possible is projected onto the outline light, thereby improving the utilization rate of the scraps; (3) One splicing strip is pressed and fixed to achieve reliable positioning. A pushing force is applied to the other splicing strip to compress the molten part. The molten quartz material fills the splicing part, avoiding the occurrence of voids at the splicing part and ensuring that Reliability of splicing; (4) The pressure block is positioned on the upper part of a splicing strip, and the top of the buffer column provides circumferential extrusion thrust at the end of another adjacent splicing strip, thereby realizing the clamping and positioning of the two splicing strips. After the splicing of the two splicing strips is heated and melted, the splicing strip is pushed towards the splicing area under the action of the buffer column, so that the molten quartz at the splicing area is squeezed, thereby filling the splicing area and avoiding voids; (5) The length of the splicing strips cut from the scrap material is uneven. The different lengths of the splicing strips are adapted by rotating the adjusting sleeve. The buffer arm rotates unidirectionally with the adjusting sleeve. During the rotation, the position of the buffer column is adjusted. After the adjustment is in place, the top of the buffer column is at the end of the splicing strip. At this time, the buffer arm is locked in the reverse direction to ensure that the buffer column can provide reliable buffer thrust to the splicing strip. Attached Figure Description

After cooling, the splicing strips 1 are connected. When two adjacent splicing strips 1 are heated and melted, one splicing strip 1 is pressed and fixed, and a pushing force is applied to the other splicing strip 1, thereby compressing the molten area.

The length of splicing strip 1 is slightly larger than the circumferential length of the last gap of the quartz ring. Generally, both ends of splicing strip 1 are 1-3mm longer. Then, heat and melt both ends of splicing strip 1. At this time, the buffer post 12 is removed, and the buffer arm 7 presses on splicing strip 1. The pre-tension spring 19 on the mounting post 17 provides clamping force to the buffer arm 7. After both ends of splicing strip 1 are melted, splicing strip 1 is pressed downward into the positioning ring groove 8. Continue heating until both ends of splicing strip 1 are completely spliced.

[0049] Example 4: A method for splicing and reusing quartz scraps (see Example 5) Figure 4 The process includes the following steps: S1, cutting the scrap material 2 into splicing strips 1; loading the scrap material 2 onto the worktable, projecting the shape outline of the product to be spliced ​​onto the worktable and the scrap material 2 using light, adjusting the position of the scrap material 2 so that it fully receives the light projection, and performing laser cutting along the light projection outline on the scrap material 2. The shape of the quartz product to be processed is projected onto the worktable using light projection. At this time, the position of the scrap material 2 on the worktable is adjusted so that as much of the scrap material 2 area as possible is projected onto the outline light, thereby improving the utilization rate of the scrap material 2. Laser cutting is used to cut along the light projection outline on the scrap material 2, which is precise and reliable. In this embodiment, the splicing strip 1 has a rectangular structure, and multiple splicing strips 1 are spliced ​​together to form a long strip-shaped quartz product. A scribing plate 3 with scribing grooves 4 is processed according to the outline dimensions of the rectangular quartz product to be processed. The scribing grooves 4 have a rectangular structure. During the scribing process, the scribing plate 3 is pressed onto the surface of the quartz scrap 2, and its position is adjusted to utilize as much of the quartz scrap 2 as possible. After the position adjustment is completed, a line is scribed along the edge of the scribing groove 4 on the surface of the scrap 2. Then, the scribed scrap 2 is transferred to a cutting machine and cut along the scribing marks to ensure cutting accuracy, forming a rectangular splicing strip 1. The ends of the splicing strip 1 are then trimmed. One end of the splicing strip 1 is trimmed into a flat structure, and the top and bottom edges of the other end are chamfered to form a trapezoidal structure. After trimming, during the splicing process of the splicing strip 1, the edge of the flat structure of one splicing strip 1 aligns with the edge of the trapezoidal structure of another splicing strip 1. During the heating and melting process, the heated area is increased, and the chamfered area provides a space for the molten material to fill the chamfered area, improving the connection strength of the splicing strip 1.

[0050] S2, the splicing strips 1 are spliced ​​together. The splicing area is heated and melted, and the splicing strips 1 are pushed to compress the molten area. After cooling, the splicing strips 1 are connected. When two adjacent splicing strips 1 are heated and melted, one splicing strip 1 is pressed and fixed, and a pushing force is applied to the other splicing strip 1, thereby compressing the molten area. Pressing and fixing one splicing strip 1 ensures reliable positioning. Applying a pushing force to the other splicing strip 1 compresses the molten area, and the molten quartz material fills the splicing area, preventing voids and ensuring the reliability of the splicing.

[0051] The splicing strip 1 is installed on the positioning platform 27 for positioning. The positioning platform 27 is provided with a long strip-shaped positioning groove 28. The positioning groove 28 is provided with slots 29 on both sides of the opposite side wall. The positioning platform 27 is equipped with a lifting buffer positioning block 30 and a sliding end positioning block 31. The bottom of the positioning groove 28 is provided with a sliding groove corresponding to the buffer positioning block 30. The sliding groove is connected to a sliding seat 32 and a sliding spring 33. The sliding spring 33 abuts against the sliding seat 32. The sliding seat 32 is slidably installed in the sliding groove. The buffer positioning block 30 is lifted and moved and connected to the sliding seat 32. The sliding seat 32 is provided with an insertion groove. The lower end of the buffer positioning block 30 is slidably installed in the insertion groove. The lifting spring is installed in the insertion groove. The lower end of the buffer positioning block 30 is supported on the lifting spring. The splicing strip 1 is loaded into the positioning groove 28. During loading, the splicing strip 1 presses down on the buffer positioning block 30. Both ends of the splicing strip 1 are inserted into the slots 29. The end positioning block 31 abuts against the end of one splicing strip 1, and the buffer positioning block 30 abuts against the end of another adjacent splicing strip 1 to provide a squeezing force. Splicing notches 34 are provided on both sides of the positioning groove 28. The splicing of the two splicing strips 1 is located at the splicing notch 34 to prevent the splicing position from being covered. Both ends of the end positioning block 31 are provided with sliders 35. Guide grooves are provided on both sides of the positioning platform 27. Guide posts are provided on the sliders 35. The guide posts are movably inserted into the guide grooves. Positioning screws are connected to the end positioning block 31. The positioning screws abut against the positioning platform 27 to position the end positioning block 31.

[0052] The two ends of the splicing strip 1 are locked in the slot 29 to achieve vertical positioning. After the two splicing strips 1 to be spliced ​​are installed into the positioning slot 28, the end positioning block 31 presses against the end of one splicing strip 1, and the buffer positioning block 30 abuts against the end of another adjacent splicing strip 1 to provide extrusion thrust. During the heating and melting process, the splicing is completed by extrusion at the splicing point.

[0053] S3, repeat S2, until the desired product shape is pieced together.

[0054] Example 5: A method for splicing and reusing quartz scraps (see Example 5) Figure 1 , Figure 2 , Figure 3 , Figure 5The process includes the following steps: S1, cutting the scrap material 2 into splicing strips 1; in this embodiment, the splicing strips 1 have a fan-shaped annular structure, and multiple splicing strips 1 are spliced ​​together to form an annular quartz product. The scrap material 2 is loaded onto a cutting table 38 for cutting. A detachable scribing plate 3 is installed on the cutting table 38. The scribing plate 3 is provided with multiple positioning rods 36. The cutting table 38 is provided with positioning holes 37 that correspond to and fit the positioning rods 36. The positioning rods 36 are positioned in the positioning holes 37. The scribing plate 3 is provided with an annular scribing groove 4 whose outline size is consistent with the outline size of the quartz product. The scribing groove 4 is coaxially arranged with the cutting table 38. The scribing plate 3 is pressed onto the scrap material 2, and the position of the scrap material 2 is adjusted so that the largest possible area on the scrap material 2 coincides with the scribing groove 4. Then the scribing plate 3 is removed to fix the scrap material 2. After that, the cutting table 38 is rotated to cut the scrap material 2. Because the scribing groove 4 is coaxially arranged with the cutting table 38, cutting is performed during the rotation of the cutting table 38 without the need for scribing. Laser cutting is used, and the laser's cutting contour matches the contour of the scribing groove 4, resulting in splicing strip 1 that is identical to the scribing groove 4. This structural design eliminates the scribing step, achieving precise cutting of the splicing strip 1. The contour dimensions of the scribing groove 4 are consistent with the contour dimensions of the quartz product. Several radially arranged ribs are connected within the scribing groove 4 to ensure the reliability of the scribing plate 3 structure. Then, the ends of the splicing strip 1 are trimmed. One end of the splicing strip 1 is trimmed into a flat structure, while the other end has chamfered edges on both sides to form a trapezoidal structure. After trimming, during the splicing process of the splicing strip 1, the edge of the flat structure of one splicing strip 1 aligns with the edge of the trapezoidal structure of another splicing strip 1. During the heating and melting process, this increases the heated area, and the chamfered edges provide accommodating space. The molten material fills the chamfered edges, improving the connection strength of the splicing strip 1.
