Description

Technical Field

[0001] The utility model belongs to the technical field of low-melting-point rubber packaging film production, and in particular relates to a continuous punching device for low-melting-point rubber packaging film. Background Art

[0002] In modern industrial manufacturing, rubber packaging film, as an important packaging material, is widely used to package and secure a variety of products. Low-melting-point rubber packaging film, in particular, has gained widespread application in the packaging industry due to its low melting point, which facilitates heat sealing and processing at specific temperatures. However, traditional rubber packaging film often suffers from poor air permeability and difficulty in venting moisture during processing and use. This not only affects the performance of the packaging film but can also adversely affect the products contained within.

[0003] Therefore, when using rubber packaging film, it is often necessary to set evenly distributed holes on the surface of the rubber packaging film. The existing punching devices often have problems such as single use, inability to adjust the hole spacing, and low punching efficiency. In addition, the packaging film waste left after the rubber packaging film is processed cannot be well collected due to static electricity or wire drawing connections at the edges of the holes, resulting in the packaging film waste being scattered around the equipment, affecting the environmental hygiene around the equipment. Utility Model Content

[0004] The main technical problem to be solved by the utility model is to provide a low-melting-point rubber packaging film continuous punching device with a simple overall structure, which can punch holes uniformly and continuously on the rubber packaging film and absorb and collect the punched packaging film waste multiple times, thereby ensuring a clean and tidy surrounding environment and improving the use effect.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0008] An anti-static device is fixedly installed above the first-level suction pipe between the two vertical plates, a second-level suction pipe is fixedly installed between the two vertical plates near the first-level suction pipe, and a second-level suction groove is opened at the lower end of the second-level suction pipe.

[0009] The following is a further optimization of the above technical solution by the present invention:

[0010] The slide bar group includes two slide bar brackets vertically arranged at both ends of the workbench in the length direction, two slide bars parallel to each other are vertically arranged between the two slide bar brackets, and at least two sliders are slidably connected to the two slide bars.

[0011] Further optimization: the punching platform includes support blocks fixedly mounted on corresponding sliders, the same first mounting plate is fixedly mounted on the upper end surfaces of all support blocks, and a discharge groove is provided at the middle position of the first mounting plate.

[0012] Further optimization: the upper surface of the first mounting plate has a linear array of multiple punching plates, which are arranged along the width direction of the discharge trough and fixedly installed at the edge of the discharge trough, and a blanking trough is opened in the middle of the punching plates.

[0013] Further optimization: the punching structure includes two sliding plates slidably connected along the top of the discharge trough, and the lower end surfaces of the two sliding plates are linearly arrayed with multiple second mounting plates, and the multiple second mounting plates correspond to the multiple punching plates. Mounting grooves are opened at positions on the second mounting plates corresponding to the corresponding discharge troughs.

[0014] Further optimization: Multiple sets of punching components can be adjusted and installed on each mounting slot through bolts.

[0015] Further optimization: the punching assembly includes a connecting head connected to the mounting groove by bolts, a mounting rod is vertically arranged at the other end of the connecting head, and a stop is provided at the other end of the mounting rod.

[0016] Further optimization: a pressure block is slidably connected to the outer surface of the mounting rod, and a spring is also sleeved on the outer surface of the mounting rod, one end of the spring is in contact with one end of the connector, and the other end of the spring is in contact with the pressure block.

[0017] Further optimization: the other end face of the baffle is located in the middle position inside the pressing block, and a punching column and a toothed sleeve are vertically arranged. The punching column is located inside the toothed sleeve, and the length of the punching column is 0.5-1mm longer than the length of the toothed sleeve.

[0018] Further optimization: an avoidance groove is opened on the end surface of the pressing block, and an O-ring is placed in the avoidance groove.

The device can also be put into an automated production line for rubber packaging film for use, which improves the utilization rate of the device. The overall structural design of the device is simple, which reduces production costs and is easy to use.

[0020] The punched rubber packaging film is first passed through an anti-static device to remove static electricity, then the waste on the bottom of the rubber packaging film is adsorbed by a first-level suction pipe, and finally the waste on the top of the rubber packaging film is adsorbed by a second-level suction pipe, which further improves the adsorption effect of the waste and plays a better protective role in the hygiene of the surrounding environment.

[0030] The adsorption assembly 9 includes two vertical plates 91 fixedly mounted at both ends of the workbench 2. A first-level suction pipe 92 is provided at a position between the two vertical plates 91 corresponding to the rubber packaging film 10. A first-level suction groove 921 is provided at the upper end of the first-level suction pipe 92.

[0031] A static eliminator 95 is fixedly installed between the two vertical plates 91 above the primary suction pipe 92. A secondary suction pipe 93 is fixedly installed between the two vertical plates 91 near the primary suction pipe 92. A secondary suction groove 94 is provided at the lower end of the secondary suction pipe 93.

[0032] The rubber packaging film 10 passes between the primary suction groove 921 and the secondary suction groove 94 .

[0033] In this embodiment, the bracket 1 is made by welding a plurality of square tubes of different lengths, and the bracket 1 is directly placed on the ground for use.

[0034] The slide bar assembly 3 includes two slide bar brackets 31 vertically arranged at both ends of the workbench 2 in the longitudinal direction, and two slide bars 32 parallel to each other are vertically arranged between the two slide bar brackets 31 .

[0035] At least two sliders 33 are slidably connected to the two slide bars 32 .

[0036] The punching platform 4 includes support blocks 41 fixedly mounted on corresponding sliders 33 , and a first mounting plate 42 is fixedly mounted on the upper end surfaces of all support blocks 41 .

[0037] A discharge groove 43 is provided in the middle of the first mounting plate 42 , and the position of the discharge groove 43 corresponds to the material receiving box 8 , that is, the material receiving box 8 is fixedly mounted on the edge of the discharge groove 43 on the bottom surface of the first mounting plate 42 .

[0038] The upper surface of the first mounting plate 42 has a plurality of punching plates 44 arranged in a linear array. The punching plates 44 are arranged along the width direction of the discharge trough 43 and fixedly installed at the edge of the discharge trough 43 .

[0039] A blanking chute 45 is provided in the middle of the punching plate 44 . With this design, the waste packaging film sheets punched off the rubber packaging film 10 fall from the blanking chute 45 and fall into the receiving box 8 after passing through the discharge chute 43 for collection.

[0040] The rubber packaging film 10 travels on a punch plate 44 .

[0041] Support plates 46 are vertically arranged at the four corners of the upper end surface of the first mounting plate 42 .

[0042] The discharge trough 43 is located at the four corner edges of the upper end surface of the first mounting plate 42 and vertical sliding columns 47 are vertically arranged.

[0043] The punching structure 5 includes a sliding plate 51 slidably connected to adjacent vertical sliding columns 47 arranged along the length direction of the discharge chute 43 through a bearing.

[0044] In this embodiment, the number of the sliding plates 51 is set to two.

[0045] A plurality of second mounting plates 52 are linearly arrayed on the lower end surfaces of the two sliding plates 51 , and the plurality of second mounting plates 52 correspond to the plurality of punching plates 44 .

[0046] The two sliding plates 51 are connected together by a plurality of second mounting plates 52 so as to slide up and down along the vertical sliding column 47 at the same time.

[0047] A mounting groove 53 is formed on the second mounting plate 52 at a position corresponding to the blanking groove 45 .

[0048] Multiple sets of punching assemblies 54 are adjustably mounted on each mounting slot 53 via bolts. The multiple sets of punching assemblies 54 are adjustably mounted on a surface of the second mounting plate 52 close to the punching plate 44 .

[0049] like Figure 6 As shown, the punching assembly 54 includes a connecting head 542 connected to the mounting groove 53 by bolts, and a mounting rod 541 is vertically arranged at the other end of the connecting head 542.

[0050] A stopper 549 is provided at the other end of the mounting rod 541 , and a pressing block 544 is slidably connected to the outer surface of the mounting rod 541 . Under the action of the stopper 549 , the pressing block 544 does not fall off.

[0051] A spring 543 is sleeved on the outer surface of the mounting rod 541 . One end of the spring 543 is in contact with one end of the connector 542 , and the other end of the spring 543 is in contact with the pressing block 544 .

[0052] With this design, the initial position of the pressing block 544 is at the position of the stop 549 .

[0053] The other end surface of the stopper 549 is located at the middle position inside the pressing block 544 and is vertically provided with a punching column 547 and a toothed sleeve 548.

[0054] The punching column 547 is located inside the toothed sleeve 548 , and the length of the punching column 547 is 0.5-1 mm longer than the length of the toothed sleeve 548 .

[0055] The toothed sleeve 548 has a plurality of teeth arranged in a circumferential array at the end thereof.

[0056] In this embodiment, the end of the punching column 547 is 1-1.5 mm shorter than the end of the pressing block 544 .

[0057] An escape groove 545 is formed on the end surface of the pressing block 544 , and an O-ring 546 is placed in the escape groove 545 .

[0058] During punching, the second mounting plate 52 drives the punching assembly 54 to fall, so that the O-ring 546 first contacts the rubber packaging film 10, and under the action of the spring 543, the rubber packaging film 10 is pressed. As the punching assembly 54 continues to fall, the pressing block 544 does not move, and the punching column 547 and the toothed sleeve 548 continue to move downward to complete the punching. The punched packaging film waste falls from the blanking chute 45 into the receiving box 8.

[0059] like Figure 3 As shown, the driving assembly 6 includes a mounting bracket 65 fixedly mounted at a middle position on the bottom surface of the first mounting plate 42 .

[0060] A sliding block 64 is fixedly mounted on the lower end surface of the mounting frame 65 .

[0061] A motor 61 is fixedly mounted in the middle of the workbench 2 near the adsorption assembly 9 , and a motor mounting plate 62 is fixedly mounted on the mounting end of the motor 61 . The motor mounting plate 62 is also fixedly mounted on the workbench 2 .

[0062] The power output end of the motor 61 passes through the motor mounting plate 62 and is fixedly mounted with a lead screw 63 .

[0063] The other end of the lead screw 63 is rotatably mounted on the workbench 2 via a bearing.

[0064] The sliding block 64 is simultaneously threadedly connected to the lead screw 63 .

[0065] With this design, the motor 61 is started, and the power output end of the motor 61 drives the lead screw 63 to rotate, so that the sliding block 64 moves left and right on the lead screw 63, driving the punching platform 4 to move left and right.

[0066] The same cylinder mounting plate 72 is fixedly mounted on the upper ends of all the support plates 46 , and the cylinder mounting plate 72 is fixedly mounted on all the vertical sliding columns 47 at the same time.

[0067] A cylinder group 7 for driving the punching structure 5 to slide up and down is fixedly mounted on the upper end surface of the cylinder mounting plate 72 .

[0068] In this embodiment, the cylinder group 7 includes four extending cylinders 71 , wherein two extending cylinders 71 form a group, and the power output ends thereof pass through the cylinder mounting plate 72 and are fixedly mounted on the corresponding sliding plate 51 .

[0069] With this design, the power output ends of the four extended cylinders 71 can drive the sliding plate 51 to slide up and down on the vertical sliding column 47, and then drive the punching assembly 54 to move up and down to complete the punching.

[0070] The receiving box 8 is connected to a drop pipe 81 at a position near the motor 61, and the other end of the drop pipe 81 is connected to a storage bag for packaging film waste. With this design, the packaging film waste accumulated in the receiving box 8 falls into the storage bag through the drop pipe 81, and then the packaging film waste is processed uniformly.

[0071] One end of the primary suction pipe 92 and the secondary suction pipe 93 passes through the corresponding vertical plate 91 and is connected to the same high-pressure blower through a hose (not shown in the figure). The other end of the high-pressure blower is connected to a storage bag for packaging film waste.

[0072] When in use, the low-melting-point rubber packaging film continuous punching device is placed in an automated production line for producing rubber packaging films 10 .

[0073] The control end of the motor 61 is electrically connected to the control system of the automated production line, the control end of the extending cylinder 71 is electrically connected to the control system of the automated production line, and the control end of the static electricity removal device 95 is electrically connected to the control system of the automated production line.

[0074] In this embodiment, the static eliminator 95 is a common static eliminator that can be purchased directly from the market. The static eliminator 95 performs a static eliminator operation on the punched rubber packaging film 10 .

[0075] Before punching, the continuous punching device for low-melting-point rubber packaging film adjusts the spacing between each set of punching components 54 according to the hole spacing requirements of the rubber packaging film 10 to match the hole spacing of the rubber packaging film 10, and then adjusts the travel speed of the rubber packaging film 10 through the control system;

[0076] When the rubber packaging film 10 to be punched moves between the punching assembly 54 and the punching plate 44, the motor 61 is started, the power output end of the motor 61 rotates, and the sliding block 64 moves in the same direction as the rubber packaging film 10, driving the punching platform 4 to move, thereby causing the punching assembly 54 to move in the same direction as the rubber packaging film 10. At this time, the control system controls the start of the extending cylinder 71 to drive the punching assembly 54 to move downward, punching the rubber packaging film 10 at this location. After punching, the extending cylinder 71 drives the punching assembly 54 Move up, and at the same time, start the motor 61 to rotate in the opposite direction, rotate the lead screw 63, drive the sliding block 64 to move in the opposite direction of the rubber packaging film 10, drive the punching platform 4 to move, and thus make the punching assembly 54 move in the opposite direction of the rubber packaging film 10 until the initial position and wait for the next area to be punched on the rubber packaging film 10 to be in place, that is, the motor 61 drives the punching assembly 54 to move back and forth in this way to perform punching. During this process, the rubber packaging film 10 is always in motion without stopping, and punching is completed here, thereby increasing the punching rate.

[0077] The flushed waste material falls into the receiving box 8 and then finally enters the storage bag through the drop pipe 81.

[0078] The punched rubber packaging film 10 still has waste materials stuck to the punched edges and electrostatically adsorbed. When the rubber packaging film 10 continues to move forward to the adsorption component 9, the static electricity removal device 95 is started to remove static electricity from the rubber packaging film 10 at this point. Then, through the first-level suction pipe 92, under the action of the high-pressure fan, the remaining waste materials attached to the lower surface of the rubber packaging film 10 are sucked away through the first-level suction groove 921. Finally, through the second-level suction pipe 93, the remaining waste materials attached to the upper surface of the rubber packaging film 10 are sucked away through the second-level suction groove 94, and finally enter the storage bag for unified treatment.

[0079] After multiple adsorptions, the waste removal rate can be improved, ensuring that the surface of the rubber packaging film 10 after punching is clean, which is beneficial to the next operation.

[0080] For ordinary technicians in this field, based on the teachings of this utility model, without departing from the principles and spirit of this utility model, changes, modifications, replacements and deformations made to the implementation methods are still within the scope of protection of this utility model.
