Description

Technical Field

[0001] The invention relates to a blank subsequent processing device, in particular to a blank side processing device. Background Art

[0002] After the production of aerated concrete blanks is completed, in order to meet the aesthetic requirements of building decoration, it is necessary to groove the blanks at appropriate positions to bury water, electricity and gas pipelines. The currently published Chinese invention patent (application number: 201510238521.5, invention name: Concrete block groove cutting equipment) discloses a groove cutting mechanism, which uses a blade for cutting. The structure of the groove cut out is single. When processing grooves with different height differences, the position of the blade cannot be adjusted, the distance between the grooves is difficult to adjust, and the structure of the grooves is also difficult to adjust.

[0003] In order to ensure the product quality of the blank, 2-4cm wide waste will be reserved below the standard size (because part of the blank material may be adsorbed on the edge of the mold, then there will be potholes in the blank after molding, and the product quality cannot be guaranteed). This waste will be cut to the target size in subsequent processing, which requires a side processing device. Currently, there is no suitable processing equipment, resulting in inefficient production processes.

[0004] In view of the above-mentioned defects, the designer actively conducts research and innovation in order to create a blank side processing device to make it more valuable for industrial use. Summary of the invention

[0005] In order to solve the above technical problems, an object of the present invention is to provide a blank side processing device.

[0006] A blank side processing device of the present invention comprises a supporting frame, in which a trimming device and a slotting device are installed;

[0007] The trimming device includes a retractable and movable scraper, which is perpendicular to the ground;

[0008] The slotting device includes a rotating seat that is an integer multiple of two, and the rotating seats are arranged symmetrically on the frame. A plurality of slotting tool holders are installed around the rotating seat, and the slotting tool holders are installed on a rotatable tool holder shaft, and slotting knives are arranged on the slotting tool holders.

[0009] The blank side processing device can be combined with a plurality of trimming devices or notching devices according to needs through a frame that can be assembled and installed.

[0010] The trimming device utilizes a retractable and movable scraper to scrape the side wall of the blank, thereby completing the waste cutting process on the side of the blank.

[0011] A rotatable rotating seat on the slotting device is used to drive different slotting tool holders to rotate. Slotting knives of different shapes and different spacings are arranged on different slotting tool holders, thereby being able to meet the needs of slotting of different shapes. When dealing with the needs of slots with different spacings, it is only necessary to rotate the rotating seat so that the corresponding slotting tool holder is located in the working area.

[0012] Furthermore, the rotating seat includes a rotating motor for driving the rotation, and the rotating motor drives the tool holder shaft to rotate. The tool holder shaft is a cube structure, and a tool holder fixing seat is fixed on its four faces by bolts, and the slotted tool holder is installed on the tool holder fixing seat.

[0013] There are multiple slotting tool holders for placing slotting knives on the slotting tool holder. The structural dimensions and spacing of the slotting knives are set according to needs. When the corresponding slotting knife is needed, the tool holder shaft is driven to rotate by a rotating motor, and the slotting knife installed on the tool holder shaft is moved to the working area to perform slotting operations on the side wall of the blank.

[0014] Furthermore, a tool holder pressure plate is movably installed on each tool holder fixing seat on the upper side through an axis, and a pressure plate cylinder is interactively installed on each tool holder pressure plate and on the tool holder shaft on the same side through an axis, and each tool holder fixing seat has a tool holder placement groove extending in the direction of the slotting tool holder, and a card block is provided on the back of the slotting tool holder to be inserted into the tool holder placement groove, and the lower edge of the tool holder pressure plate contacts the upper edge of the card block, and each lower tool holder fixing seat has a card block limiting groove extending in the direction of the slotting tool holder, and the card block at the lower end of the slotting tool holder is inserted into the card block limiting groove.

[0015] The slotting tool holder is a detachable structure. The block installed on the back of the slotting tool holder is clamped in the tool holder placement slot on the tool holder fixing seat. The installation is convenient and quick through such hanging method, which is more efficient for the replacement and maintenance of the slotting knife and the slotting tool holder.

[0016] Furthermore, the tool holder mounting groove has a structure that is wide at the top and narrow at the bottom, the size of the upper part is consistent with the outer diameter of the clamping block, a limiting block is fixed on the outer side of the tool holder mounting groove by bolts, the clamping block limiting groove and the tool holder mounting groove are located on the same straight line, the internal width of the clamping block limiting groove is consistent with the outer diameter of the clamping block, and a limiting block is fixed on the outer side of the clamping block limiting groove by bolts.

[0017] The wider structure on the upper part of the tool holder limiting groove cooperates with the outer wall of the clamping block to play a limiting role. At the same time, the end face is limited by the stopper outside the tool holder placement groove. Such a structure can fix and limit the position of the slotting tool holder to prevent it from sliding.

[0018] Furthermore, there is an auxiliary positioning frame for the slotting tool holder in the middle of each surface of the tool holder shaft, and the end of the auxiliary positioning frame has a bayonet for limiting the inner end surface of the slotting tool holder, and the auxiliary positioning frame has a supporting block extending from the back of the slotting tool holder.

[0019] Since the slotting tool holder is relatively long, the middle part is supported and positioned by an auxiliary positioning frame to prevent the middle part of the slotting tool holder from being deformed due to force, resulting in the slotting tool depth position not being guaranteed, thereby ensuring the accuracy of the slotting.

[0020] Furthermore, a plurality of screw rods are welded on the rear side of the scraper, and the screw rods pass through the through holes on the scraper fixing rod and then nuts are tightened at both ends of the scraper fixing rod to fix the scraper fixing rod, and the scraper fixing rod is installed on the scraper support.

[0021] The scraper is installed on the frame through a scraper support, and a cutting edge is opened on the scraper in the direction of the blank's advance, so that the side wall of the blank can be scraped during the blank's advance to remove the pre-reserved surplus.

[0022] Furthermore, the scraper support is pushed forward and backward by the scraper cylinder.

[0023] The scraper is installed on the scraper support, and the scraper support moves back and forth driven by the scraper cylinder to remove waste from blanks of different size requirements.

[0024] Furthermore, the scraper support includes a mounting plate fixed on the frame, two sets of slider supports are fixed on the mounting plate, a scraper slider is fixed on the slider support, a scraper slide rail is installed on the scraper slider, a scraper push plate is fixed to the front end of the scraper slide rail by bolts, and scraper fixing rods are installed at the upper and lower ends of the scraper push plate through a scraper fixing rod mounting seat.

[0025] The scraper support is installed on the scraper slide rail, and the scraper slide rail is movably installed on the scraper slider. The scraper position is adjusted by pushing the scraper push plate at its front end by the scraper cylinder.

[0026] Furthermore, a waste cutting device is installed at the front end of the frame, which includes multiple groups of cutting wires, each group of cutting wires is installed on a corresponding wire rack, the wire rack is installed on a wire rack push plate, the inner side of the wire rack push plate is connected to the wire rack push cylinder through an adapter frame, the upper and lower ends of the wire rack push plate are fixedly connected to the ends of the wire rack slide rail by bolts, the wire rack slide rail is installed on the wire rack slider, the wire rack slider is fixed to the wire rack fixed plate by bolts, and the wire rack fixed plate is installed on the frame.

[0027] Through the obliquely pulled cutting wire, a layer of the side wall of the blank is first scraped off, and the cutting wire is driven by the wire rack pushing cylinder to move forward and backward, so as to facilitate the adjustment of the cutting position.

[0028] Furthermore, the wire rack is inclined and has multiple auxiliary support plates on it. A wire fixing seat is provided at the bottom of the wire rack, a wire guide wheel is provided at the top of the wire rack, and a wire pulling cylinder is also installed on the top of the wire rack. The wire pulling cylinder pulls the cutting wire, and there is a groove on the outside of the auxiliary support plate. After the cutting wire is inserted into the groove, it passes around the wire guide wheel and is fixedly connected to the wire pulling cylinder.

[0029] A wire pulling cylinder is installed on the wire rack to keep the wire in a taut state, and a plurality of auxiliary support plates are used to support and maintain the position of the wire to ensure the cutting effect.

[0030] Furthermore, an extension bracket is fixed to the frame in front of the cutting wire by bolts, and a vertical cutting tool holder is fixed to the bottom of the extension bracket by bolts. Multiple sets of side cutter fixing seats are installed on the surface of the cutting tool holder. The side cutters are fixed in the openings at the ends of the side cutter support rods by means of bolts and nuts. The threaded section on the side cutter support rod passes through the through holes on the side cutter fixing seats and then locking nuts are screwed into the side ends thereof.

[0031] In order to facilitate the cutting of the blank by the cutting wire, the side wall of the blank is scratched by multiple horizontal side cutting knives before cutting. In this way, when the cutting wire is cut, the side wall of the blank will not be subjected to excessive force, resulting in more blanks being brought out and the blanks being damaged.

[0032] Through the above scheme, the present invention has at least the following advantages: this blank side processing device can complete the blank side processing by dividing and cutting the blank side and then grooving it, and can ensure the flatness of the blank side wall.

[0033] Moreover, the slotting cutter can be quickly replaced according to the needs, which improves the rapid change for different slotting situations, increases the application scope of the equipment, and also improves the efficiency of slotting structure changes.

DETAILED DESCRIPTION

[0052] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0053] See also Figure 1-4 The device for processing the side of the blank is divided into a trimming device 2 and a slotting device 3. The blank is transported from Figure 1 The blank enters from the middle right side, and the scraper 4 on the trimming device 2 trims the excess waste on the side wall of the blank so that the size of the blank meets the production requirements.

[0054] After cutting, the blank enters the working position of the slotting device 3, and the different slotting tool holders 5 are rotated to the inner side of the device by rotating the rotating seat 8, and the slotting knife 7 installed on the slotting tool holder 5 is rotated to a position close to the blank. There are slotting knives 7 of various sizes and specifications on the slotting tool holder 5 for cutting different slots, and there are multiple groups of slotting tool holders 5, which can meet the slotting requirements for different products by rotating.

[0055] See also Figure 4 The tool holder shaft 6 is a rotatable structure, which is driven by the rotating motor 9 to rotate the tool holder shaft 6. The tool holder shaft 6 is a regular polygon. A tool holder fixing seat 10 is installed on each surface of the tool holder shaft 6. The slotting tool holder 5 can be placed on the tool holder fixing seat 10. When different slotting knives 7 are needed, the tool holder shaft 6 is rotated to move the corresponding slotting knife 7 to the inner channel position of the slotting device 3. The slotting operation of the blank can be completed in the process of the blank moving forward.

[0056] See also Figure 6-9 , is a partial enlarged schematic diagram of the upper and lower tool holder fixing seats 10. The upper tool holder fixing seat 10 has a tool holder placement groove 13. The tool holder placement groove 13 is wide at the top and narrow at the bottom. The wider structure at the top matches the outer diameter of the clamping block 14. After the clamping block 14 is inserted, it plays an upper and lower limit. The lower tool holder fixing seat 10 is used for the upper and lower through grooves of the part where the clamping block 14 is inserted. Because the upper position of the slotting tool holder 5 is fixed by the upper tool holder fixing seat 10, the lower tool holder fixing seat 10 only needs front and rear limit.

[0057] The upper limit of the slotting tool holder 5 is limited by the tool holder pressure plate 11, and the tool holder pressure plate 11 is movably installed on the upper tool holder fixing seat 10 through an axis. At the same time, the middle part is movably connected with the extended rod of the pressure plate cylinder 12 through an axis, and the tail end of the pressure plate cylinder 12 is movably installed on the tool holder shaft 6 through an axis. When installing the slotting tool holder 5, the pressure plate cylinder 12 retracts and lifts the tool holder pressure plate 11 to expose the tool holder placement groove 13 on the tool holder fixing seat 10. After the clamping block 14 on the slotting tool holder 5 is inserted into the tool holder placement groove 13, the pressure plate cylinder 12 is reset to press the lower edge of the tool holder pressure plate 11 on the upper edge of the clamping block 14 to complete the locking and fixing installation of the slotting tool holder 5.

[0058] See also Figure 6-9 In order to limit the left and right horizontal position of the block 14 on the slotting tool holder 5, two blocks are fixed by bolts on the outer sides of the corresponding tool holder placement groove 13 and the block limit groove 15. The spacing between the blocks is consistent with the rod outer diameter between the block 14 and the slotting tool holder 5, and the gap between the tool holder placement groove 13 and the block limit groove 15 and the block just matches the thickness of the block 14. In this way, the block 14 can be restricted up and down and left and right, and the downward restriction is guaranteed by the weight of the slotting tool holder 5 itself.

[0059] See also Fig.10 In order to provide auxiliary support for the middle part of the slotting tool holder 5, an auxiliary positioning frame 16 is fixed to the tool holder shaft 6 by bolts. The end of the auxiliary positioning frame 16 has an open slot-like structure. The width of this slot just matches the thickness of the slotting tool holder 5. When installing, the middle part of the slotting tool holder 5 is inserted into the slot to achieve positioning installation. At the same time, there is a support block 17 extending outward on the auxiliary positioning frame 16. The support block 17 is located at the rear part of the slotting tool holder 5 to support the rear part of the slotting tool holder 5. In this way, when the slotting tool holder 5 is slotting the blank, it will not be affected by the force, resulting in deformation of the middle part of the slotting tool holder 5, thereby ensuring the slotting effect. When necessary, multiple sets of auxiliary positioning frames 16 can be used for positioning and support.

[0060] See also Figure 1 , Figure 2 and Fig.11The trimming device 2 includes multiple groups of scrapers 4 located on both sides of the blank. The scrapers 4 can move forward and backward to scrape the side walls of the blank to remove waste. The scrapers 4 have multiple screws 18 that penetrate the scraper fixing rod 19. Nuts are screwed into the screws 18 on both sides of the scraper fixing rod 19. The position of the scrapers 4 is fixed by the locking force of the nuts. By adjusting the position of the nuts, the extension distance of the scrapers 4 can be adjusted.

[0061] See also Fig.11 There is a mounting platform on both sides of the column of the frame 1, and a scraper cylinder 21 for ejecting the scraper support 20 is installed on the side wall of the mounting platform. When the scraper cylinder 21 is working, it can drive the scraper support 20 to move forward and backward, so the scraper 4 installed on the scraper support 20 can move forward and backward to meet the needs of adjusting the position of the scraper 4.

[0062] See also Fig.11 , in the above-mentioned installation platform, there are multiple slider supports 23 and scraper sliders 24 arranged in rows, the slider slider 24 is a fixed structure, and the scraper slide rail 25 is installed on the scraper slider 24, so that the scraper slide rail 25 can be directed forward and backward based on the scraper slider 24, and a scraper cylinder 21 for pushing is installed on the installation platform, the scraper cylinder 21 is connected to the scraper push plate 26 through an adapter, and the scraper push plate 26 is connected to the scraper fixing rod 19. Therefore, when the scraper cylinder 21 is running, the position of the scraper 4 can be moved to achieve the purpose of mechanized adjustment, and the industrial computer is used for control to achieve precise regulation, and multiple groups of scrapers 4 can be arranged in a stepped manner to gradually complete the side leveling and cutting of the blank, avoiding the first group of scrapers 4 from cutting too much, resulting in peeling and damage to the side wall of the blank.

[0063] See also Figure 1 , Fig.12 as well as Fig.13 The waste cutting device 28 pre-cuts the side wall of the blank through multiple cutting wires 29, and then scrapes and flattens it by the subsequent process scraper 4. The cutting wire 29 is installed on the wire rack 30, and the wire rack 30 is fixed on the wire rack push plate 31 by bolts. The position of the wire rack push plate 31 is driven by the wire rack push cylinder 33 to move it back and forth to move the cutting wire 29 to the corresponding working area. The depth of the multiple cutting wires 29 is inconsistent. Figure 1 The depth from left to right increases successively, so that the cutting process of the blank is cut in sequence, avoiding excessive cutting at one time, which causes damage to the blank. The wire rack push plate 31 is installed on the wire rack slider 35 through the wire rack hanging ghost 34, and the wire rack pushing cylinder 33 is used to complete the forward and backward movement to achieve the purpose of control.

[0064] See also Fig.13 In order to ensure that the cutting wire 29 is always in a taut state, the wire pulling cylinder 40 installed at the upper end of the wire rack 30 is used to pull it backward, and the wire guide wheel 39 on the wire rack 30 is used as a switching mechanism for guidance, so that the cutting wire 29 relies on the wire guide wheel 39 for transmission, which is convenient for tensioning, and there are multiple supporting auxiliary support plates 37 on the side wall of the wire rack 30, and there is a groove on the end face of the auxiliary support plate 37. The depth of this groove is consistent with the cutting wire 29. When ensuring that the support column cuts the wire 29, it will not slide out of the slide groove on the side wall of the blank, ensuring that the side wall of the blank is intact.

[0065] See also Figure 1 and Fig.14 Before cutting the waste on the side wall of the blank, multiple sets of side cutters 45 are set to slide out multiple grooves on the blank. In this way, during the cutting process of the blank, the entire surface of the blank will not be subjected to a large cutting force, making the cutting of the blank easier. The cutting of the waste will not bring out materials within the specifications of the blank, ensuring the stability and smoothness of the subsequent cutting. The entire side cutter 45 is fixed by bolts and nuts, and the depth of the side cutter 45 can be determined by the installation position of the side cutter bracket 44 at its tail end.

[0066] The working principle of the present invention is as follows:

[0067] See also Figure 1 The moving direction of the blank is from left to right in the figure. The side cutting knife 45 first opens a plurality of grooves on the side wall of the blank. The groove divides the entire side of the blank into a plurality of long strip-shaped planes. In the subsequent cutting process, the local force on the side will not be very large, and the intact part of the blank will not be taken out. As the depth of the blank advances, it first moves to the position of the waste cutting device 28, and the cutting wire 29 is moved by the waste cutting device 28, and is arranged in a stepped manner from left to right, so that the cutting wire 29 completes the cleaning and cutting operation of the side wall of the waste in turn, avoiding the situation that the whole piece of material is peeled off when cutting thicker waste. After the wire 29 is cut, the blank moves to the right, at which point the blank enters the position of the trimming device 2. The depth of the scraper 4 on the trimming device 2 is the same as that of the cutting wire 29, and the left-to-right direction is arranged in a stepped manner, and trimming is performed in sequence. The scraper 4 also has a leveling function, which makes the side wall of the blank smooth and tidy. After being scraped and leveled by the scraper 4, it is finally transferred to the position of the slotting device 3 for slotting. When slotting, the corresponding slotting tool holder 5 is selected according to the product design, and the corresponding slotting tool holder 5 is moved to the slotting station under the drive of the rotating motor 9, so as to achieve the purpose of efficiently switching the slotting tool holder 5 and meet different slotting requirements.
