Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of glasses case processing, in particular to an EVA material feeding mechanism of a glasses case shell material processing device. Background Art
[0002] The original meaning of a glasses case is actually a box for glasses. The shell material of existing glasses cases is usually a composite material, which is composed of five layers of leather, film, EVA, film, and cloth bonded in sequence. During the processing of this composite material, workers usually manually cover and bond the five materials in sequence. During the bonding process, the edges of each layer must be aligned, which will cause waste. In addition, bubbles and bulges between the two layers must be avoided during the bonding process. After perfect alignment, fixings are fixed at both ends before processing them into glasses cases. The process is very troublesome and inefficient. Utility Model Content
[0003] In summary, in order to overcome the deficiencies of the prior art, the utility model provides an EVA material feeding mechanism for a processing device for conveying more stable glasses case shell materials.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a feeding mechanism for EVA material of a processing device for eyeglass case shell material, comprising a conveyor belt and a limit member, the limit member is located on the side of the conveyor belt facing the connecting mechanism in the processing device, a gap is provided between the limit member and the conveyor belt, the conveyor belt is provided with a pushing member, and the pushing member is linked to the conveying surface of the conveyor belt.
[0005] With such an arrangement, when in use, the leather material and a rubber film are first placed on the first feed roller and the second feed roller respectively, and then the other rubber film and the cloth are placed on the third feed roller and the fourth feed roller, or vice versa. Multiple sheets of EVA material are stacked and placed on the conveyor belt. When processing is required, the equipment is started, the conveyor belt starts to operate, and the EVA material on the conveyor belt is sent to the processing position on the processing device. When the conveyor belt is operating, the pushing member on its belt surface will move therewith. The height of the pushing member is not greater than the thickness of a single piece of EVA material. In this way, when it moves, it can push the bottom sheet from the bottom of the EVA material pile to the gap position below the limit member. The transmission process is more stable with the help of the pushing member, not just relying on friction.
[0006] Furthermore, the pushing member is rod-shaped, and the axis of the pushing member is arranged parallel to the axis of the driving roller of the conveyor belt.
[0007] With this arrangement, the long rod will be placed horizontally on the conveyor belt and push the EVA sheet from the entire side, with a larger contact area, making the push more stable and without damaging the side.
[0008] Furthermore, linkage chains are provided on both sides of the conveyor belt, and both ends of the pushing member are respectively connected to one of the linkage chains.
[0009] With this arrangement, the driving rollers at both ends of the conveyor belt will be connected synchronously by a linkage chain, and the rod-shaped pushing member is connected to the linkage chain and linked therewith, so that its movement is more stable and there will be no loose connection between the pushing member and the belt surface of the conveyor belt.
[0010] Furthermore, the pushing member is plug-connected with the linkage chain.
[0011] With such arrangement, the long rod-shaped pusher will be inserted between two sections of the chain as a connecting piece as the latch of the linkage chain, without welding, easy to install and stable in transmission.
[0012] Furthermore, at least two pushing members are provided, and the two pushing members are evenly distributed in the conveying direction of the conveyor belt.
[0013] With this arrangement, the conveyor belt can push the EVA sheet once every half rotation, which is more efficient.
[0014] Furthermore, a sensing component is provided above the conveyor belt, and the sensing component senses the height of the material on the conveyor belt to control the opening and closing of the processing device.
[0015] With this arrangement, the sensing component can determine the number of EVA sheets from the height of the EVA material pile. When the height is lower than a certain number or the number returns to zero, the sensing component will shut down the processing device to prevent the device from operating without EVA material, producing waste or even damaging parts.
[0016] Furthermore, the sensing component is an infrared sensor.
[0017] With this arrangement, when there is a lot of EVA material on the conveyor belt, the infrared sensor will irradiate the EVA material, and the shutdown effect will not be triggered at this time. When the EVA material decreases or even runs out, the infrared sensor will pass through the top of the EVA material, and the induction will be triggered at this time, shutting down the processing device and waiting for loading before the next processing. The structure is simple.
[0018] Furthermore, it also includes a pressurizing component, which includes a first cylinder and a pressurizing plate. The frame of the processing device is located at the position of the conveyor belt and is provided with a pressurizing frame. The first cylinder is connected to the pressurizing frame. The first cylinder is set toward the conveyor belt. The pressurizing plate is connected to the output head of the first cylinder, and the pressurizing plate is located above the conveyor belt.
[0019] With such a setting, the pressing assembly will continuously apply pressure to the stacked EVA sheets on the conveyor belt, enabling them to closely adhere to the conveyor belt and be driven by the frictional force of the conveyor belt without bouncing during transportation and causing inability to continue pushing. The combined action of the pressing assembly and the pushing member is more stable. When in use, the first cylinder will press down the pressing plate at the output head position, and the pressing plate will press on the EVA sheets to apply pressure to them. Using a cylinder as the pressing device has a small output force, is easier to control, and is not likely to cause a situation where the conveyor belt cannot drag the EVA sheets due to excessive pressure. When the infrared sensor senses the lack of materials, the pressing plate is first lifted before shutting down the machine, and then pressed down again after feeding.
[0020] Furthermore, side plates are provided on the sides of the pressing plate and are arranged facing away from the conveyor belt.
[0021] With such a setting, the side plates can prevent the edges of the pressing plate from scratching other parts.
[0022] Furthermore, a relief groove is provided at the position of the side plates corresponding to the sensing assembly.
[0023] With such a setting, the infrared sensor can pass through from the position of the relief groove to shut down the processing device and will not be blocked by it, resulting in misjudgment of the height. Description of the Drawings

[0030] With such an arrangement, when in use, the leather material and a film are first placed on the first feed roller 202 and the second feed roller 203 respectively, and then the other film and the cloth are placed on the third feed roller 204 and the fourth feed roller 205, or vice versa. Multiple sheets of EVA material are stacked and placed on the conveyor belt 201. When processing is required, the equipment is started, the conveyor belt 201 starts to operate, and the EVA material on the conveyor belt 201 is sent to the processing position on the processing device. When the conveyor belt 201 is operating, the pushing member 2011 on its belt surface will move therewith. The height of the pushing member 2011 is not greater than the thickness of a single piece of EVA material. In this way, when it moves, it can push the bottom sheet from the bottom of the EVA material pile to the gap position below the limit member 206. The transmission process is more stable with the help of the pushing member 2011, not only relying on friction.
[0031] Preferably, in this embodiment, the pushing member 2011 is rod-shaped, and the axis of the pushing member 2011 is arranged parallel to the axis of the driving roller of the conveyor belt 201 .
[0032] With such arrangement, the long rod will be placed horizontally on the conveyor belt 201 and push the EVA sheet from the entire side, so that the contact area is larger, the pushing is more stable and the side will not be damaged.
[0033] Preferably, in this embodiment, linkage chains 2012 are provided on both sides of the conveyor belt 201 , and both ends of the pushing member 2011 are respectively connected to one of the linkage chains 2012 .
[0034] With such arrangement, the driving rollers at both ends of the conveyor belt 201 will be connected synchronously by the linkage chain 2012, and the rod-shaped pushing member 2011 is connected to the linkage chain 2012 and linked thereto, so that its movement is more stable, and there will be no loose connection between the pushing member 2011 and the belt surface of the conveyor belt 201.
[0035] Preferably, in this embodiment, the pushing member 2011 is plug-connected with the linkage chain 2012 .
[0036] With such arrangement, the long rod-shaped pusher 2011 will be inserted between two sections of the linkage chain 2012 as a connecting piece as the latch pin of the linkage chain 2012, without welding, and is easy to install and has stable transmission.
[0037] Preferably, in this embodiment, at least two pushing members 2011 are provided, and the two pushing members 2011 are evenly distributed in the conveying direction of the conveyor belt 201 .
[0038] With such arrangement, the conveyor belt 201 can push the EVA sheet once every half rotation, which is more efficient.
[0039] Preferably, in this embodiment, a sensing component 2013 is provided above the conveyor belt 201, and the sensing component 2013 senses the height of the material on the conveyor belt 201 to control the opening and closing of the processing device.
[0040] With this arrangement, the sensing component 2013 can determine the number of EVA sheets from the height of the EVA material pile. When the height is lower than a certain number or the number returns to zero, the sensing component 2013 will shut down the processing device to prevent the device from operating without EVA material to produce waste or damage parts.
[0041] Preferably, in this embodiment, the sensing component 2013 is an infrared sensor.
[0042] With such an arrangement, when there is a lot of EVA material on the conveyor belt 201, the infrared sensor will irradiate the EVA material, and the shutdown effect will not be triggered at this time. When the EVA material decreases or even runs out, the infrared sensor will pass through the top position of the EVA material, and the induction will be triggered at this time, shutting down the processing device and waiting for loading before the next processing. The structure is simple.
[0043] Preferably, this embodiment further includes a pressurizing component 207, wherein the pressurizing component 207 includes a first cylinder 2071 and a pressurizing plate 2072.
