Description

Technical Field

[0001] The utility model relates to the technical field of sheet processing, and particularly relates to a scraping device. Background Art

[0002] In the production process of calcium carbide plates, scraping processing is a key step to ensure that the edges of the plates are neat and smooth to meet the requirements of subsequent processing or use.

[0003] Currently, in order to reduce the scraping cost, the traditional scraping method is that workers manually scrape the edges of calcium carbide plates with tools. The labor intensity is relatively high, and only one side of the calcium carbide plate can be scraped at a time, and the scraping efficiency is also relatively limited.

[0004] Therefore, this application provides a scraping device to solve the above technical problems. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide a scraping device to solve the problems of high operation intensity and low efficiency of the existing manual scraping.

[0006] To solve the above technical problems, the utility model provides the following technical solutions:

[0007] A scraping device includes a base. Two side plates are symmetrically and fixedly arranged on the upper end face of the base. A plurality of horizontally arranged guide rollers are rotatably installed between the bottoms of the two side plates. A top plate is fixed between the tops of the two side plates. A cylinder is installed on the top plate. The machine shaft of the cylinder vertically penetrates the lower end face of the top plate and is fixed with a fixing plate. An activity frame is elastically installed on the lower end face of the fixing plate. A horizontal pressing roller is rotatably installed at the bottom of the activity frame.

[0008] On the opposite sides of the two side plates, installation frames that can move mirror-symmetrically are symmetrically arranged. Scraping tools are detachably installed on the opposite sides of the two installation frames.

[0009] Optionally, the installation frame is an L-shaped frame body. A T-shaped clamping groove is formed on the side surface of the installation frame, and the scraping tool is vertically and slidably clamped and installed in the clamping groove. A handle is fixed on the top of the scraping tool.

[0010] Optionally, a connecting rod is fixed in the middle of the side of the installation frame away from the scraping tool. The connecting rod horizontally penetrates the middle of the side plate and is fixed with a movable plate. A lead screw is rotatably installed in the base. Opposite thread sections are respectively formed at both ends of the lead screw, and the two opposite thread sections respectively penetrate the bottoms of the two movable plates.

[0011] Optionally, a screw hole for the lead screw to pass through is provided at the bottom of the movable plate, and one end of the lead screw extends out of the side surface of the base and is fixed with a handle.

[0012] Optionally, a plurality of positioning grooves are formed around the outer edge surface of one end of the lead screw extending outside the side surface of the base, a fixing block is fixed to the side surface of the base, a positioning pin is vertically inserted into the fixing block, the top end of the positioning pin is plugged into the positioning groove, and a second spring is connected between the bottom of the positioning pin and the fixing block.

[0013] Optionally, vertical limiting columns are symmetrically fixed at both ends of the top of the movable frame, and limiting holes for the limiting columns to vertically penetrate are symmetrically opened at both ends of the fixed plate.

[0014] Optionally, a first spring is sleeved on the limiting column, one end of the first spring is fixed to the movable frame, and the other end of the first spring is fixed to the fixed plate.

[0015] Compared with the prior art, the utility model has at least the following beneficial effects:

[0016] In the above scheme, thanks to the detachable mounting structure of the mounting frame and the scraping tool, the scraping tool can be easily pulled out from the clamping groove to perform subsequent maintenance and quick replacement of the scraping tool, which is easy to use.

[0017] At the same time, thanks to the cooperation of the mounting frame, the movable plate and the lead screw, the mirror-image movement of the two mounting frames can be controlled by rotating the lead screw, thereby driving the two scraping tools to abut the two sides of the calcium carbide plate to be scraped, so as to cooperate with the conveying of the calcium carbide plate to perform simultaneous scraping processing on both sides. This not only assists the staff to reduce the labor intensity during scraping, but also makes the double scraping more efficient and has a good use effect.

[0018] In addition, thanks to the movable frame elastically installed on the lower end surface of the fixed plate, the pressure roller installed on the lower end surface of the movable frame can cooperate with the guide roller to jointly perform upper and lower abutment and limit on the calcium carbide plates of different thicknesses, thereby reducing the activity of the calcium carbide plates and improving the scraping effect of the calcium carbide plates to a certain extent.

[0032] As Figure 1 shown, an embodiment of the present utility model provides a scraping edge device, including a base 1. Two side plates 2 are symmetrically fixed on the upper end face of the base 1. A plurality of horizontally arranged guide rollers 3 are rotatably installed between the bottoms of the two side plates 2. A top plate 4 is fixed between the tops of the two side plates 2. A cylinder 5 is installed on the top plate 4. The machine shaft of the cylinder 5 vertically penetrates the lower end face of the top plate 4 and is fixed with a fixing plate 6. The lower end face of the fixing plate 6 is elastically installed with a movable frame 7. A horizontal pressure roller 8 is rotatably installed at the bottom of the movable frame 7.

[0033] Cooperating Figure 4 as shown, two vertical limit columns 701 are symmetrically fixed at both ends of the top of the movable frame 7. Limit holes 601 for the vertical penetration of the limit columns 701 are symmetrically opened at both ends of the fixing plate 6. A first spring 702 is sleeved on the limit columns 701. One end of the first spring 702 is fixed on the movable frame 7, and the other end is fixed on the fixing plate 6, so that the movable frame 7 is elastically installed on the lower end face of the fixing plate 6, and the guide roller 3 and the pressure roller 8 can cooperate to elastically abut and limit the calcium carbide plate up and down.

[0034] As shown Figure 1 and Figure 2 in the figure, mounting brackets 9 that can move mirror-symmetrically are symmetrically arranged on one side of the two side plates 2 facing each other, and scraping edge tools 10 are detachably mounted on one side of the two mounting brackets 9 facing each other. Specifically, the mounting bracket 9 is an L-shaped frame body, a T-shaped clamping groove 901 is formed on the side surface of the mounting bracket 9, and the scraping edge tool 10 is vertically and slidably clamped and installed in the clamping groove 901, so that the scraping edge tool 10 can be quickly installed on the mounting bracket 9, and a handle 1001 is fixed on the top of the scraping edge tool 10, which can facilitate the extraction and replacement of the scraping edge tool 10 through the handle 1001.

[0035] At the same time, a connecting rod 902 is fixed in the middle of one side of the mounting bracket 9 away from the scraping edge tool 10. The connecting rod 902 horizontally penetrates through the middle of the side plate 2 and is fixed with a movable plate 903. A lead screw 11 is rotatably installed in the base 1, and opposite thread sections are respectively formed at both ends of the lead screw 11. The two opposite thread sections respectively penetrate through screw holes 904 formed at the bottom of the corresponding positions of the two movable plates 903. Therefore, when the lead screw 11 rotates, the opposite thread sections at both ends of the lead screw 11 can be used to control the mirror-symmetric movement of the movable plate 903 to drive the mounting bracket 9, so as to adjust the distance between the two scraping edge tools 10 to adapt to calcium carbide plates of different widths.

[0036] Cooperate Figure 3 as shown in the figure, one end of the lead screw 11 extends out of the side surface of the base 1 and is fixed with a handle 12. Among them, a plurality of positioning grooves 1101 are formed in a surrounding manner on the outer edge surface of the end of the lead screw 11 extending out of the side surface of the base 1. A fixed block 13 is fixed on the side surface of the base 1, a positioning pin 14 is vertically inserted into the fixed block 13, the top end of the positioning pin 14 is inserted and matched with the positioning groove 1101, and a second spring 15 is connected between the bottom of the positioning pin 14 and the fixed block 13. Therefore, the positioning pin 14 can be elastically installed on the fixed block 13, and the positioning pin 14 automatically abuts against the positioning groove 1101 at the end of the lead screw 11 under the action of elastic force for limiting, so as to prevent the lead screw 11 from moving after rotation and affecting the distance between the two scraping edge tools 10.

[0037] The working principle provided by the present utility model for this edge scraping device is as follows. During use, the calcium carbide plate can be placed on the guide roller 3 for conveying. During this process, the air cylinder 5 can be started to drive the fixed plate 6 to drive the movable frame 7 to descend, so as to use the pressure roller 8 in cooperation with the guide roller 3 to elastically abut and limit the calcium carbide plate. And the screw rod 11 is rotated through the handle 12 to control the two movable plates 903 to drive the mounting frame 9 to drive the two edge scraping cutters 10 to move mirror-symmetrically, so as to abut against both sides of the calcium carbide plate to be edge-scraped, and to perform simultaneous edge scraping processing on both sides of the calcium carbide plate in cooperation with the conveying of the calcium carbide plate. This not only helps the staff to reduce the labor intensity during edge scraping, but also has a higher double-edge scraping efficiency and good use effect.
