Description

Technical Field

[0001] This utility model relates to the field of shell processing and positioning technology, and in particular to an automatic shell folding device. Background Technology

[0002] The automatic shell folding device precisely addresses the needs of the packaging and related manufacturing industries for automation, efficiency, and standardization. It overcomes the problem that traditional machinery cannot be compatible with various shell structures such as "cross-clamping" and "glue bonding," achieving multi-functional integrated folding and expanding the applicable scenarios of automated equipment.

[0003] Existing technologies, such as the utility model patent with publication number CN116749088A, disclose a motor housing processing device, including: a polishing mechanism for polishing the inner and outer sides of the motor housing. The polishing mechanism includes an inner polishing component, an outer polishing component, and a linkage component. The inner and outer polishing components are both connected to the linkage component, which is connected to a reciprocating screw. The rotation of the reciprocating screw can drive the linkage component to move up and down. The inner polishing component can polish the inner side of the motor housing, and the outer polishing component can polish the outer side of the motor housing. In the motor housing processing device of the present invention, the transmission component drives the fixing component to first fix the motor housing, and then drives the motor housing to rotate. At the same time, the outer ring rotates, causing the swinging part to swing and change the sandblasting angle of the second sandblasting head, so that the connection between the motor housing and the heat dissipation fins can be effectively polished.

[0004] In industrial production and daily life, it has been found that during the production and processing of workpieces, different sizes of workpieces need to be processed, which requires the use of molds of different sizes. Since the molds of general shell folding devices are fixed in a single size, they cannot be used for workpieces of different sizes. This makes it inconvenient to process workpieces of different sizes uniformly. During the processing, the inability to quickly change to a suitable mold can easily lead to problems such as excessively long processing cycles, increased costs, and reduced production efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the problem that, during the use of an automatic folding device for duvet covers, the inability of a typical automatic folding device for duvet covers to change molds and adapt to workpieces of different sizes leads to increased labor costs and reduced production efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides an automatic shell folding device, comprising: a workbench, a work frame fixedly connected to the upper surface of the workbench, an electrical control cabinet fixedly connected to the side wall surface of the work frame, a cylinder fixedly connected to the upper surface of the work frame, a folding pressure plate fixedly connected to the output end of the cylinder, two fixing devices arranged on the upper surface of the workbench corresponding to the position of the folding pressure plate, the two fixing devices being distributed on both sides of the upper surface of the workbench, a mold table mounted on the upper surface of the workbench with the aid of the fixing devices, a conveyor frame arranged on one side of the upper surface of the workbench, and each fixing device including two fixing plates, the lower surfaces of the two fixing plates being fixedly connected to the upper surface of the workbench. A connecting plate is fixedly connected to one side of the two fixed plates that are close to each other. Sliding blocks are slidably connected to both sides of the connecting plate. A screw is threaded through the upper surface of the connecting plate. An auxiliary plate is rotatably connected to the lower surface of the screw. An auxiliary strip, which is a rubber strip, is fixedly connected to the upper surface of the auxiliary plate. The upper surface of the auxiliary strip is slidably connected to the arc surface of the screw. A locking block is fixedly connected to one side of the two sliding blocks that are close to each other. A locking groove is opened on the side wall surface of the mold table corresponding to the position of the locking block. The surface of the locking block is inserted into the inner wall of the locking groove. Several positioning grooves are opened on the lower surface of the two sliding blocks. The lower surface of the several positioning grooves abuts against the upper surface of the auxiliary strip.

[0007] The effect achieved by the above components is as follows: during the clamping and fixing of the mold table, the fixing device can be used to clamp and fix the mold table. At this time, the position of the mold table is fixed by the engagement between the locking block on the surface of the sliding block and the locking groove on the surface of the mold table. The position of the sliding block on the surface of the connecting plate is fixed by the mutual abutment between the positioning groove on the lower surface of the sliding block and the auxiliary strip, so that the fixed mold table will not loosen.

[0008] Preferably, auxiliary rods are fixedly connected to both sides of the upper surface of the auxiliary plate, the arc surfaces of the two auxiliary rods are slidably connected to the upper surface of the auxiliary strip, and the arc surfaces of the two auxiliary rods are slidably connected to the upper surface of the connecting plate.

[0009] The effect achieved by the above components is that the two auxiliary rods fixed to the surface of the auxiliary plate are slidably connected to the surface of the connecting plate, which prevents the auxiliary strip from rotating, ensures that the surface of the auxiliary strip fits in contact with the surface of the positioning groove, and fixes the position of the sliding block.

[0010] Preferably, the upper surface of the worktable is provided with a plurality of fixing grooves corresponding to the position of the mold table, and the upper surface of the plurality of fixing grooves abuts against the lower surface of the mold table.

[0011] The effect achieved by the above components is that by using several fixing grooves that abut against the lower surface of the mold table, the friction between the lower surface of the mold table and the upper surface of the worktable can be increased, thus preventing the mold table from sliding on the upper surface of the worktable.

[0012] Preferably, the cross-section of the card block is a right-angled trapezoid, and the card block is a cemented carbide block.

[0013] The effect achieved by the above components is that by using a hard alloy block with a right-angled trapezoidal cross-section, the wear of the block can be reduced, and the engagement between the block and the slot can be made more convenient.

[0014] Preferably, the upper surface of the conveyor frame is provided with a guiding device, which includes two partitions and two auxiliary blocks. The lower surfaces of the two partitions are fixedly connected to the upper surface of the conveyor frame. The upper surfaces of the two partitions are fixedly connected to the same auxiliary frame. The inner walls of the auxiliary frame are provided with several limiting grooves on both sides. The two auxiliary blocks are fixedly connected with connecting blocks on both sides. The inner walls of the two connecting blocks are rotatably connected with rotating blocks. The rotating blocks have a hook-shaped cross-section. The inner wall surface of the rotating blocks abuts against the inner wall surface of the limiting grooves. The upper surfaces of the two auxiliary blocks are provided with positioning holes. The inner arc surface of the positioning holes is slidably connected to a sliding rod. The arc surface of the sliding rod is fitted with a spring. The two sides of the spring are fixedly connected to the surface of the sliding rod and the upper surface of the auxiliary block, respectively. The lower surfaces of the two auxiliary blocks are fixedly connected with clamping plates.

[0015] The effect achieved by the above components is as follows: during the process of guiding and conveying the workpiece, the guiding device can be used to guide and convey the workpiece. At this time, the position of the auxiliary block is fixed by the mutual contact between the rotating block and the surfaces of several limiting grooves. The clamps fixedly connected to the lower surfaces of the two auxiliary blocks can play a role in guiding the workpiece.

[0016] Preferably, each of the two clamping plates has two pulleys rotatably connected to its surface, and the two pulleys are evenly distributed on the surface of the clamping plates.

[0017] The effect achieved by the above components is that by rotating and connecting two pulleys on the surface of the clamping plate, the process of guiding the workpiece through the clamping plate becomes smoother, thus improving the efficiency of guiding the workpiece.

[0018] Preferably, the two clamps are inclined on the side where they are close to each other, and the two clamps are located on the side where the two partitions are close to each other.

[0019] The effect achieved by the above components is that by using two clamping plates that are inclined on one side close to each other, the efficiency of workpiece guidance can be improved and the wear of the clamping plates can be reduced.

[0020] Compared with related technologies, the automatic folding device for duvet covers provided by this utility model has the following beneficial effects:

[0021] This utility model provides an automatic shell folding device. During the clamping and fixing of the mold table, a fixing device can be used to clamp and fix the mold table. At this time, the mold table can be fixed on the workbench surface by the engagement between the locking block on the surface of the sliding block and the locking groove on the surface of the mold table. By providing several fixing grooves on the surface of the workbench, the fixing of the mold table on the workbench surface can be assisted. By the mutual abutment between the auxiliary strip and the positioning groove on the lower surface of the two sliding blocks, the fixed mold table can be prevented from loosening. By using hard alloy locking blocks with a right-angled trapezoidal cross section, the wear of the locking blocks can be reduced and the service life of the locking blocks can be extended.

[0022] During the process of guiding and conveying workpieces, a guiding device can be used to guide and convey workpieces. At this time, the position of the auxiliary block relative to the auxiliary frame can be fixed by the mutual abutment between the rotating block and several limiting grooves. By using two inclined clamping plates with two pulleys on their surfaces, the guiding process of the guiding device for workpieces can be made smoother, saving costs, improving guiding efficiency, reducing the wear of the clamping plates, and extending the service life of the clamping plates.

[0036] The working principle of the automatic shell folding device provided by this utility model is as follows: When it is necessary to fix the position of the mold table 6, the fixing device 7 above the workbench 1 can be used to fix the mold table 6. First, the fixing device 7 is used to fix the mold table 6. The cylinder 4 on the upper surface of the work frame 3 is started by the electrical control cabinet 2, so that the cylinder 4 drives the folding pressure plate 5 to process the workpiece on the mold table 6. Since it is necessary to process workpieces of different sizes, it is necessary to fix the mold table 6 of different sizes. The mold table 6 can be placed on the upper surface of the workbench 1, so that the lower surface of the workbench 1 abuts against the surface of several fixing grooves 711. By pushing the sliding block 707, the locking block 710 is locked with the locking groove 709. The screw 704 is rotated, so that the auxiliary plate 706 drives the auxiliary strip 705 to move upward, so that the upper surface of the auxiliary strip 705 abuts against the surface of several positioning grooves 708 on the lower surface of the two sliding blocks 707; so that the mold table 6 is fixed on the upper surface of the workbench 1 at the position corresponding to the folding pressure plate 5.

[0037] During the process of transferring workpieces, the conveyor frame 8 above the workbench 1 can be used to transfer the workpieces. Since the workpieces will deflect and accumulate during the transfer process, it is necessary to guide the workpieces. The workpieces can be guided by using the guide device 9. By moving the auxiliary block 906 upward, the upper surface of the sliding rod 908 can be made to abut against the lower surface of the auxiliary frame 902. By rotating the rotating block 904, the inner wall surface of the rotating block 904 can be made to abut against the surface of several limiting grooves 903, thus fixing the position of the auxiliary block 906. The inclined clamping plate 910 fixed below both auxiliary blocks 906 can improve the efficiency of workpiece guidance. The two pulleys 911 rotatably connected to the surface of the clamping plate 910 can make the workpiece guidance action smoother.
