Description

Technical Field

[0001] This utility model relates to the field of chip conveyor technology, and in particular to a chip conveyor safety protection device and a chip conveyor. Background Technology

[0002] Machine tool chip conveyors are classified into chain plate chip conveyors, scraper chip conveyors, spiral chip conveyors, and permanent magnet chip conveyors, which can handle various types of chips; they can also be used as conveying devices for small parts of stamping and cold heading machine tools.

[0003] Chain-plate chip conveyors are mainly used for collecting and conveying various types of rolled, lumpy, and blocky chips, as well as copper, aluminum, and stainless steel chips that cannot be handled by magnetic chip conveyors. Various types of chip conveyors are disclosed, as shown in patents CN207873785U and CN107363616A. However, current chip conveyors lack safety protection. Specifically... Figure 1 As mentioned above, at the outlet of the chip conveyor's conveying channel, a collection box is often installed below the outlet. When the collection box is full, as the chain plate continuously circulates, it will scrape the chips from the bottom wall of the conveying channel into the conveying channel. At the same time, if the chip gets caught in the chip during operation and is not handled properly, the operator's hand may also get caught, causing a safety hazard. Utility Model Content

[0004] Based on the above, the purpose of this utility model is to provide a safety protection device and chip conveyor for chip conveyors, to ensure the normal operation of the chip conveyor, and to prevent safety accidents or chip residue from being scraped back to the bottom of the chip conveyor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] On the one hand, this utility model provides a safety protection device for a chip conveyor, including a drive mechanism, a chain plate, and a controller. The drive mechanism drives the chain plate to rotate cyclically on the chip conveyor's conveying channel. A control switch and an elastic pressure plate are provided on the bottom wall of the chip conveyor's conveying channel near the outlet. The control switch is located below the elastic pressure plate and is electrically connected to the controller. The controller is electrically connected to the drive mechanism.

[0007] When the elastic pressure plate is passively pressed, the elastic pressure plate moves down and triggers the control switch. The controller controls the drive mechanism to stop rotating or controls the drive mechanism to reverse the set angle.

[0008] Furthermore, the elastic pressure plate includes a mounting base plate and a pressing plate. The mounting base plate is disposed on the bottom wall of the conveying channel. One side of the pressing plate is connected to the mounting base plate. The pressing plate is located below the mounting base plate and extends upward at an angle. The pressing plate and the mounting base plate form an angle.

[0009] The control switch is located below the pressing plate.

[0010] Furthermore, a first mounting hole is provided on the bottom wall, and a second mounting hole corresponding to the first mounting hole is provided on the mounting base plate, and the control switch is mounted on the first mounting hole and the second mounting hole.

[0011] On the other hand, a chip conveyor is provided, including the chip conveyor safety protection device described above.

[0012] The beneficial effects of this utility model are as follows:

[0013] This utility model provides a safety protection device and a chip conveyor. When the elastic pressure plate is passively pressed, it moves downward, triggering the control switch. The controller then controls the drive mechanism to stop rotating or reverses the drive mechanism by a set angle. When the collection box is full of chips or a person's hand is caught in the chip, the drive mechanism continues to rotate forward. Driven by the chain plate, the chain plate squeezes the chips or the person's hand, causing the elastic pressure plate to be pressed down. This triggers the control switch, causing the drive mechanism to stop rotating or reverse. This ensures the normal operation of the chip conveyor and prevents safety accidents, or the chips are scraped back to the bottom of the chip conveyor. Attached Figure Description

[0026] Example 1

[0027] In existing technologies, a collection box is often installed at the chip discharge outlet of a chip conveyor to collect chips and debris. This presents two potential hazards. First, if the collection box is full and not emptied in time, the chips and debris will be scraped back into the conveyor channel 4. Second, when the chips and debris are scraped back into the conveyor channel 4, the entire chip conveyor may jam. If the operator operates improperly and tries to pull out the chips and debris by hand, their hand risks being caught in the conveyor channel 4. Therefore, this utility model embodiment provides a safety protection device for a chip conveyor to address these hazards.

[0028] like Figures 2 to 5 The present invention provides a safety protection device for a chip conveyor, comprising a drive mechanism 1, a chain plate 2, and a controller 3. The drive mechanism 1 is a motor, and the controller 3 is a PLC controller 3. The drive mechanism 1 drives the chain plate 2 to rotate cyclically on the chip conveyor conveying channel 4. The specific principle of the chip conveyor is prior art and will not be elaborated here. A control switch 6 and an elastic pressure plate 5 are provided on the bottom wall 41 of the chip conveyor conveying channel 4 near the outlet. The control switch 6 includes, but is not limited to, a tactile switch, a push-button switch, a micro switch, and a pressure-sensitive switch. The control switch 6 is located below the elastic pressure plate 5 and is electrically connected to the controller 3, which is electrically connected to the drive mechanism 1. When the elastic pressure plate 5 is passively pressed, the elastic pressure plate 5 moves down, triggering the control switch 6. The controller 3 controls the drive mechanism 1 to stop rotating or controls the drive mechanism 1 to reverse by a set angle.

[0029] In this embodiment of the invention, when the collection box is full of debris or a person's hand is caught in it, since the debris or hand is between the elastic pressure plate 5 and the chain plate 2, if the drive mechanism 1 continues to rotate forward, the chain plate 2 will squeeze the debris or the person's hand under the drive of the chain plate 2, causing the elastic pressure plate 5 to be pressed down. The control switch 6 is triggered, causing the drive mechanism 1 to stop rotating or reverse, preventing the debris or hand from being caught in, preventing safety accidents, or the debris is scraped back to the bottom of the chip conveyor.

[0030] In some embodiments, such as Figure 3 and 4As shown, the elastic pressure plate 5 includes a mounting base plate 52 and a pressing plate 51. The mounting base plate 52 is disposed on the bottom wall 41 of the conveying channel 4 and is fixedly connected to the bottom wall 41 by screws. One side of the pressing plate 51 is connected to the mounting base plate 52. The connection position of the pressing plate 51 and the mounting base plate 52 forms an arc shape, so that the pressing plate 51 has a certain elasticity. The pressing plate 51 is located below the mounting base plate 52 and extends upward at an angle. The pressing plate 51 and the mounting base plate 52 form an angle. The control switch 6 is located below the pressing plate 51. Specifically, when there are debris or a hand between the chain plate 2 and the pressing plate 51, the chain plate 2 continues to move forward. Since the pressing plate 51 is tilted upward and has elasticity, the chain plate 2 will squeeze the debris or hand, causing the pressing plate 51 to be moved downward. The pressing plate 51 then triggers the control switch 6, thereby triggering the drive mechanism 1 to stop rotating or reverse a certain distance.

[0031] In some embodiments, such as Figure 3 As shown in Figure 4, in order to fix the control switch 6, a first mounting hole 411 is provided on the bottom wall 41, and a second mounting hole 521 corresponding to the first mounting hole 411 is provided on the mounting base plate 52. The control switch 6 is mounted on the first mounting hole 411 and the second mounting hole 521.
