Description

Technical Field

[0001] This utility model relates to the field of tempered glass processing technology, and more specifically, it relates to a protective device for tempered glass processing. Background Technology

[0002] Tempered glass is widely used in various industries such as construction, automobiles, and home appliances due to its excellent safety performance. However, there are significant safety hazards during the production and processing of tempered glass, especially in the cutting process. Because tempered glass has high hardness and toughness, it easily produces small, sharp glass fragments during cutting. These fragments, flying at high speeds, can not only damage production equipment but, more importantly, threaten the safety of operators.

[0003] Traditional protective measures, such as wearing protective glasses and gloves, can reduce injury to some extent, but they cannot fundamentally solve the problem of flying glass shards. Therefore, how to effectively control and collect glass shards generated during the cutting process while ensuring production efficiency has become a pressing technical challenge in the tempered glass processing industry. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a protective device for tempered glass processing. By setting up a protective roll, during the processing of tempered glass, the screw drives the lifting rod to rise and pull the protective roll to unfold, enclosing the outside of the glass. This effectively blocks the glass fragments generated during the cutting process from flying, significantly reducing the potential harm to operators and production equipment. Furthermore, by controlling the glass fragments inside the protective roll, subsequent cleaning is more convenient.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a protective device for tempered glass processing, comprising a processing table, with uprights installed through each of the four corners of the processing table, and a rotatable roller connected between the lower ends of two adjacent uprights, with a protective roll wound on the roller, and an automatic winding mechanism provided between the roller and the protective roll, a clearance groove for the protective roll to pass through on the processing table, and a lifting rod provided at the other end of the protective roll, with a lead screw provided on each upright, and a motor for driving the lead screw to rotate on the upright, a first connecting block threaded on the lead screw, and a support rod opposite to the lead screw provided on an adjacent upright, with a second connecting block slidably sleeved on the support rod, the first connecting block and the second connecting block being fixedly connected to both ends of the lifting rod respectively.

[0006] The present invention is further configured such that: a limiting block is provided at the upper end of the support rod, and the limiting block is used to abut against the second connecting block.

[0007] The present invention is further configured such that the processing table has annular retaining edges on the inner sides of the four supports.

[0008] The present invention is further configured such that: the worktable has a through groove circumferentially opened on the inner side of the annular retaining edge, and a chip collection box is provided at the bottom of the processing table.

[0009] The present invention is further configured such that: the automatic winding mechanism includes a coil spring wound on the spool, one end of the coil spring is fixedly connected to the outer wall of the spool, and the other end of the coil spring is fixedly connected to one end of the protective roll material.

[0010] In summary, this utility model has the following beneficial effects:

[0011] 1. With the protective roll installed, when processing tempered glass, the screw drives the lifting rod to rise and pull the protective roll to unfold, enclosing the outside of the glass. This effectively blocks the glass fragments generated during the cutting process from flying, significantly reducing the potential injury to operators and production equipment. Furthermore, by controlling the glass fragments inside the protective roll, subsequent cleanup is more convenient.

[0012] 2. After the protective roll material loses the tension of the lifting rod, it can be rewound onto the roll under the action of the automatic winding mechanism, thus returning to its initial state, which facilitates subsequent glass loading and unloading operations;

[0013] 3. The four protective rolls are independently controlled to unfold and retract, allowing for full or partial unrolling as needed during operation, making the protective device more flexible. Attached Figure Description

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] Reference Figures 1-3 A protective device for tempered glass processing includes a processing table 1, with uprights 2 fixedly attached to each of the four corners of the processing table 1. A roller 3 is rotatably connected between the lower ends of two adjacent uprights 2. A protective roll 4 is wound on the roller 3. The protective roll 4 is a roll of cloth with a multi-layer composite structure design, which has high strength and is not easily broken when impacted by glass fragments. An automatic winding mechanism is provided between the roller 3 and the protective roll 4. A clearance groove is provided on the processing table 1 for the protective roll 4 to pass through. A lifting rod 5 is fixedly attached to the other end of the protective roll 4. A lead screw 6 is rotatably connected to each upright 2. A motor for driving the lead screw 6 to rotate is fixedly attached to the upright 2. A first connecting block 7 is threaded onto the lead screw 6. A support rod 8 opposite to the lead screw 6 is fixedly attached to an adjacent upright 2. A second connecting block 9 is slidably attached to the support rod 8. The first connecting block 7 and the second connecting block 9 are respectively fixedly connected to the two ends of the lifting rod 5.

[0023] A limiting block 10 is fixedly sleeved on the upper end of the support rod 8. The limiting block 10 is used to abut against the second connecting block 9. By setting the limiting block 10, the second connecting block 9 is prevented from sliding excessively on the support rod 8, thereby avoiding damage caused by excessive unfolding of the protective roll 4.

[0024] The processing table 1 has annular baffles 11 fixed on the inner side of the four supports. During the cutting of tempered glass, the debris that splashes from the cutting surface of the glass has the strongest impact force when it hits the annular baffles 11 due to the linearity and speed of its trajectory. The annular baffles 11 can effectively block these debris in front of the protective roll 4, thereby enhancing the overall protective effect. The processing table has a through groove 12 on the inner side of the annular baffles 11. A chip collection box (not shown in the figure) is set at the bottom of the processing table 1. Some debris falls into the chip collection box through the through groove 12 during the processing, while the other part of the debris is blocked on the processing table 1. After the processing is completed, the debris only needs to be swept to the through groove 12, and the debris can fall into the chip collection box through the through groove 12 and be collected. The cleaning process is simpler and more efficient.

[0025] The automatic winding mechanism includes a coil spring 13 wound around the spool 3. One end of the coil spring 13 is fixedly connected to the outer wall of the spool 3, and the other end of the coil spring 13 is fixedly connected to one end of the protective roll 4. When the protective roll 4 is pulled, it will cause the coil spring 13 to deform elastically. When the protective roll 4 loses tension, the coil spring 13 can provide a restoring force to realize the function of the spool 3 rewinding the protective roll 4.

[0026] Working Principle: This protective device is used to protect tempered glass during the cutting process, effectively blocking flying glass shards and ensuring operator safety. In use, the tempered glass to be processed is first placed on the processing table 1. Then, the motor is started, driving the lead screw 6 to rotate. This drives the first connecting block 7 to rise along the lead screw 6 under the action of the thread, causing the support rod 8 and the second connecting block 9 to move accordingly. The support rod 8 pulls the protective roll 4 to gradually unfold, forming a barrier that effectively blocks flying glass shards generated during cutting. After processing, the motor drives the lead screw 6 to rotate in the opposite direction, driving the first connecting block 7, support rod 8, and second connecting block 9 to move downwards as a whole. The support rod 8 no longer applies force to the protective roll 4. At this time, the protective roll 4 is automatically wound back onto the roll 3 by the winding mechanism, returning to its initial state for subsequent glass loading and unloading operations. Furthermore, the four protective rolls 4 can be independently controlled for unfolding and rewinding, allowing for full or partial unwinding as needed, making the protective device more flexible.

[0027] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
