Description

Technical Field

[0001] The utility model relates to the technical field of rubber processing, in particular to a rubber strip cutting machine. Background Art

[0002] Rubber is divided into natural rubber and synthetic rubber. Natural rubber mainly comes from the Hevea brasiliensis tree. When the skin of this rubber tree is cut, a milky white juice called latex will flow out. The latex is condensed, washed, molded and dried to obtain natural rubber. Synthetic rubber is made by artificial synthesis. Different types of rubber can be synthesized using different raw materials. Rubber products refer to the activities of producing various rubber products using natural and synthetic rubber as raw materials, and also include rubber products produced from waste rubber. The rubber industry is one of the important basic industries of the national economy. It not only provides people with daily necessities, medical and other light industrial rubber products that are indispensable in daily life, but also provides various rubber production equipment or rubber parts to heavy industries and emerging industries such as mining, transportation, construction, machinery, and electronics.

[0003] At present, the existing utility model with publication number CN202592421U discloses a rubber strip cutting machine, including multiple rollers, the rollers are installed on the roller shaft, there are guide sleeves at both ends of the roller shaft, there is a rolling rod under the roller, the roller shaft and the rolling rod are driven by gears and move in opposite directions.

[0004] In the above scheme, the roller cutter rod in the prior art is usually made of hard plastic material. During use, in order to completely cut the rubber into strips, it is necessary to ensure that the roller cutter and the roller cutter rod are in close contact. Otherwise, the sealing strips after cutting will be connected to each other, and manual cutting will be required for a second time. If the roller cutter and the roller cutter rod are in close contact, the roller cutter rod will be cut into many strips if the roller cutter is used for a long time. The roller cutter rod needs to be replaced regularly, and the roller cutter blade will also be greatly worn, thereby increasing the cutting cost. Utility Model Content

[0005] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a rubber strip cutting machine. By providing a cutter and a shearing block, the rubber is cut into strips under the action of the cutter and the shearing block, thereby solving the problem of the prior art that the roller bar needs to be replaced regularly and the cutter is easily worn, thereby reducing the cutting cost of the cutter and ensuring that the cut rubber will not be connected to each other.

[0006] The solution of the utility model to solve the technical problem is:

[0007] A rubber strip cutting machine comprises a frame, a workbench is fixed on the upper end of the frame, a plurality of rubbers are placed on the upper end of the workbench, an adjusting assembly and two rollers are arranged on the upper end of the frame, one of the rollers is rotatably connected to the side wall of the frame, and the other roller is arranged on the adjusting assembly, a driving mechanism and a guiding assembly are arranged on the upper end of the frame, the driving mechanism comprises a linkage assembly and a driving assembly, a mounting frame is arranged on the linkage assembly, a cutter is fixed on the lower end of the mounting frame, a shear block staggered with the cutter is fixed on the upper end of the frame, and an intermittent assembly is arranged on the upper end of the frame.

[0008] When the rubber needs to be cut into strips, the spacing between the two rollers is adjusted by the adjustment component, so that the rollers can drive the rubber of the required thickness to be transported. Multiple pieces of rubber are placed on the upper end of the workbench, and one end of the rubber is against the side wall of the roller. The driving component is started, thereby driving the linkage component and the intermittent component to work at the same time. The linkage component drives the mounting frame and the cutter to reciprocate, and under the action of the guide component, the mounting frame is moved in a specified direction, so that the cutter will not deflect or vibrate when it reciprocates. The intermittent component drives one of the rollers to rotate intermittently, thereby driving the multiple pieces of rubber to be transported intermittently. When the multiple pieces of rubber are transported intermittently, the other roller is driven to rotate intermittently, so that the multiple pieces of rubber can be effectively transported intermittently. When the cutter moves downward to shear the rubber, the multiple pieces of rubber are stopped from being transported at the same time under the action of the intermittent component, and the rubber is cut into strips under the action of the shear block, ensuring that the cut rubber will not be connected to each other. When the cutter moves upward to reset, the multiple pieces of rubber are transported at the same time under the action of the intermittent component. Repeating the above operation can cut the rubber into strips uninterruptedly, thereby improving the efficiency of rubber cutting.

[0009] By providing a cutter and a shear block, the rubber is cut into strips under the action of the cutter and the shear block, which solves the problem of the prior art that the roller rod needs to be replaced regularly and the cutter is easily worn, thereby reducing the cutting cost of the cutter and ensuring that the cut rubber strips will not be connected to each other.

[0010] The utility model is further configured as follows: the adjustment component includes two slide grooves symmetrically formed on the side walls of the frame, wherein both ends of one roller are rotatably connected to a slider that cooperates with the slide groove, and the upper end of the slider is rotatably connected to a screw rod, which is screwed to the frame.

[0011] Through the above technical solution, when the distance between the two rollers needs to be adjusted, the two screws are rotated to drive the two sliders to move, and the movement of the two sliders drives one of the rollers to move, so that the distance between the two rollers can be adjusted.

[0012] The utility model is further configured as follows: the linkage assembly includes a connecting shaft rotatably connected to the side wall of the frame, two eccentric disks are symmetrically fixed on the side wall of the connecting shaft, the eccentric disk is eccentrically arranged to the connecting shaft, a linkage rod is rotatably connected to the side wall of the eccentric disk, the linkage rod is coaxially arranged with the eccentric disk, and the mounting frame is rotatably connected to the lower ends of the two linkage rods at the same time.

[0013] Through the above technical solution, when it is necessary to drive the cutter to reciprocate, the driving assembly is started, thereby driving the connecting shaft to rotate, and the rotation of the connecting shaft simultaneously drives the two eccentric disks to rotate, and the rotation of the two eccentric disks simultaneously drives the two linkage rods to reciprocate, and the two linkage rods reciprocate simultaneously to drive the mounting frame to reciprocate, thereby driving the cutter to reciprocate.

[0014] The utility model is further configured as follows: the driving assembly includes a first pulley fixed to the end of the connecting shaft, a rotating shaft is rotatably connected to the side wall of the frame, a second pulley is fixed at each end of the rotating shaft, a third pulley is rotatably connected to the side wall of the frame, belts are installed between the first pulley and one of the second pulleys and between the third pulley and the other second pulley, a motor is fixed to the side wall of the frame, and the output end of the motor is fixed to the side wall of one of the second pulleys.

[0015] Through the above technical solution, when it is necessary to drive the connecting shaft to rotate, the motor is started to drive the second pulley to rotate. The rotation of the second pulley drives the first pulley to rotate through the belt, thereby driving the connecting shaft to rotate.

[0016] The utility model is further configured as follows: the guide assembly includes a plurality of guide rods fixed at equal distances on the upper end of the frame, and the upper end of the mounting frame is formed with a plurality of through holes that cooperate with the guide rods.

[0017] With the above technical solution, when the cutter reciprocates, the mounting frame reciprocates in a specified direction by providing a plurality of guide rods, so that the cutter will not deflect or vibrate during the reciprocating motion, thereby ensuring that the quality of the rubber strips is not affected.

[0018] The utility model is further configured as follows: the intermittent assembly includes a driven gear fixed to the end of one of the rollers, and an intermittent gear matching the driven gear is fixed on the side wall of the third pulley.

[0019] Through the above technical scheme, when it is necessary to drive multiple pieces of rubber for intermittent transportation, the motor is started to drive the second pulley to rotate, and the rotation of the second pulley drives the third pulley to rotate through the belt, thereby driving the intermittent gear to rotate, and when the teeth of the intermittent gear and the driven gear are meshed and rotated with each other, the driven gear is driven to rotate, and the rotation of the driven gear drives the roller to rotate, thereby driving multiple pieces of rubber for transportation, and when multiple pieces of rubber are transported, the upper roller is driven to rotate, thereby effectively driving the rubber for transportation, and when the teeth of the intermittent gear are disengaged from the driven gear, the driven gear stops rotating, thereby stopping the roller, and stopping the roller stops the transportation of multiple pieces of rubber, and repeating the above operation can drive multiple pieces of rubber for intermittent transportation.

[0020] The utility model is further configured as follows: an inclined conveying platen and a collecting platen are fixed to the upper end of the frame, and the collecting platen is located at the lowest end of the conveying platen.

[0021] Through the above technical solution, when the rubber strips are cut, the inclined conveying table can make the cut rubber slide onto the collecting table to prevent the cut rubber from being directly under the cutter, thereby facilitating the collection of the cut rubber by the staff.

[0022] The beneficial effects of the utility model are:

[0023] Compared with the prior art, the invention provides a cutter and a shear block, so that the rubber can be cut into strips under the action of the cutter and the shear block, thereby solving the problem of the prior art that the roller bar needs to be replaced regularly and the cutter is easily worn, thereby reducing the cutting cost of the cutter and ensuring that the cut rubber strips will not be connected to each other.

DETAILED DESCRIPTION

[0030] The following is a further detailed description of the specific implementation of the present invention 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.

[0031] The following references Figures 1 to 5 The utility model is described.

[0032] A rubber strip cutting machine comprises a frame 1, a workbench 2 is fixed to the upper end of the frame 1, a plurality of rubbers 3 are placed on the upper end of the workbench 2, an adjusting assembly and two rollers 4 are arranged on the upper end of the frame 1, one of the rollers 4 is rotatably connected to the side wall of the frame 1, and the other roller 4 is arranged on the adjusting assembly, a driving mechanism and a guide assembly are arranged on the upper end of the frame 1, the driving mechanism comprises a linkage assembly and a driving assembly, a mounting frame 5 is arranged on the linkage assembly, a cutter 6 is fixed to the lower end of the mounting frame 5, a shear block 7 staggered with the cutter 6 is fixed to the upper end of the frame 1, and an intermittent assembly is arranged on the upper end of the frame 1.

[0033] When the rubber 3 needs to be cut into strips, the spacing between the two rollers 4 is adjusted by the adjustment component, so that the rollers 4 can drive the rubber 3 of the required thickness to be conveyed, and multiple pieces of rubber 3 are placed on the upper end of the workbench 2, and one end of the rubber 3 is against the side wall of the roller 4, and the driving component is started, thereby driving the linkage component and the intermittent component to work at the same time. The linkage component drives the mounting frame 5 and the cutter 6 to reciprocate, and under the action of the guide component, the mounting frame 5 moves in a specified direction, so that the cutter 6 will not deflect or vibrate when it reciprocates, and the intermittent component drives one of the rollers 4 to rotate intermittently. When the multiple rubbers 3 are intermittently transported, another roller 4 is driven to rotate intermittently, thereby effectively driving the multiple rubbers 3 to be intermittently transported. When the cutter 6 moves downward to shear the rubber 3, the multiple rubbers 3 are stopped from being transported at the same time under the action of the intermittent component, and the rubber 3 is cut into strips under the action of the shear block 7 to ensure that the cut rubbers 3 are not connected to each other. When the cutter 6 moves upward to reset, the multiple rubbers 3 are transported at the same time under the action of the intermittent component. By repeating the above operation, the rubber 3 can be cut into strips uninterruptedly, thereby improving the efficiency of cutting the rubber 3.

[0034] By providing a cutter 6 and a shear block 7, the rubber 3 is cut into strips under the action of the cutter 6 and the shear block 7, thereby solving the problem of the prior art that the roller bar needs to be replaced regularly and the cutter 6 is easily worn, thereby reducing the cutting cost of the cutter 6 and ensuring that the cut rubber 3 will not be connected to each other.

[0035] The adjustment assembly includes two slide grooves 101 symmetrically formed on the side wall of the frame 1, and one of the two ends of a roller 4 is rotatably connected to a slider 8 that cooperates with the slide groove 101, and the upper end of the slider 8 is rotatably connected to a screw rod 9, which is screwed to the frame 1.

[0036] When the distance between the two rollers 4 needs to be adjusted, the two screw rods 9 are rotated to drive the two sliders 8 to move. The movement of the two sliders 8 drives one of the rollers 4 to move, so that the distance between the two rollers 4 can be adjusted.

[0037] The linkage assembly includes a connecting shaft 10 rotatably connected to the side wall of the frame 1, two eccentric disks 11 are symmetrically fixed on the side wall of the connecting shaft 10, the eccentric disk 11 is eccentrically arranged with the connecting shaft 10, a linkage rod 12 is rotatably connected to the side wall of the eccentric disk 11, the linkage rod 12 is coaxially arranged with the eccentric disk 11, and the mounting frame 5 is rotatably connected to the lower ends of the two linkage rods 12 at the same time.

[0038] When it is necessary to drive the cutter 6 to reciprocate, start the driving assembly to drive the connecting shaft 10 to rotate. The rotation of the connecting shaft 10 drives the two eccentric disks 11 to rotate at the same time. The rotation of the two eccentric disks 11 drives the two linkage rods 12 to reciprocate at the same time. The reciprocating movement of the two linkage rods 12 drives the mounting frame 5 to reciprocate at the same time, thereby driving the cutter 6 to reciprocate.

[0039] The driving assembly includes a first pulley 13 fixed to the end of the connecting shaft 10, a rotating shaft 14 is rotatably connected to the side wall of the frame 1, a second pulley 15 is fixed at each end of the rotating shaft 14, a third pulley 16 is rotatably connected to the side wall of the frame 1, a belt 17 is installed between the first pulley 13 and one of the second pulleys 15, and between the third pulley 16 and the other second pulley 15, a motor 18 is fixed to the side wall of the frame 1, and the output end of the motor 18 is fixed to the side wall of one of the second pulleys 15.

[0040] When the connecting shaft 10 needs to be driven to rotate, the motor 18 is started to drive the second pulley 15 to rotate. The rotation of the second pulley 15 drives the first pulley 13 to rotate through the belt 17, thereby driving the connecting shaft 10 to rotate.

[0041] The guide assembly includes a plurality of guide rods 19 equidistantly fixed to the upper end of the frame 1 , and a plurality of through holes 501 cooperating with the guide rods 19 are formed on the upper end of the mounting frame 5 .

[0042] When the cutter 6 reciprocates, the plurality of guide rods 19 are provided to make the mounting frame 5 reciprocate in a specified direction, so that the cutter 6 will not deflect or vibrate during the reciprocating motion, thereby ensuring that the quality of the cut rubber 3 is not affected.

[0043] The intermittent assembly includes a driven gear 20 fixed to the end of one of the rollers 4 , and an intermittent gear 21 matching the driven gear 20 is fixed on the side wall of the third pulley 16 .

[0044] When it is necessary to drive multiple pieces of rubber 3 for intermittent conveying, start the motor 18 to drive the second pulley 15 to rotate. The rotation of the second pulley 15 drives the third pulley 16 to rotate through the belt 17, thereby driving the intermittent gear 21 to rotate. When the teeth of the intermittent gear 21 mesh with the driven gear 20 and rotate, the driven gear 20 is driven to rotate. The rotation of the driven gear 20 drives the roller 4 to rotate, thereby driving multiple pieces of rubber 3 for conveying. When multiple pieces of rubber 3 are conveyed, the upper roller 4 is driven to rotate, thereby effectively driving the rubber 3 for conveying. When the teeth of the intermittent gear 21 are disengaged from the driven gear 20, the driven gear 20 stops rotating, thereby stopping the roller 4 from rotating. The roller 4 stops rotating and stops conveying multiple pieces of rubber 3. Repeat the above operation, thereby driving multiple pieces of rubber 3 for intermittent conveying.

[0045] An inclined conveying platen 22 and a collecting platen 23 are fixed to the upper end of the frame 1 , and the collecting platen 23 is located at the lowest end of the conveying platen 22 .

[0046] When the rubber 3 is cut into strips, the inclined conveying table 22 can make the cut rubber 3 slide onto the collecting table 23 to prevent the cut rubber 3 from being directly under the cutter 6, thereby facilitating the collection of the cut rubber 3 by the staff.

[0047] Working principle:

[0048] When the rubber 3 needs to be cut into strips, the two screw rods 9 are rotated to drive the two sliders 8 to move. The movement of the two sliders 8 drives one of the rollers 4 to move, so as to adjust the distance between the two rollers 4, place multiple pieces of rubber 3 on the upper end of the workbench 2, and make one end of the rubber 3 rest against the side wall of the roller 4, start the motor 18, drive the second pulley 15 to rotate, the second pulley 15 rotates and drives the first pulley 13 and the third pulley 16 to rotate through the belt 17, so as to drive the connecting shaft 10 to rotate, and the intermittent gear 21 to rotate. The rotation of the connecting shaft 10 drives the two eccentric disks 11 to rotate at the same time. The rotation of the two eccentric disks 11 drives the two linkage rods 12 to reciprocate at the same time. The two linkage rods 12 reciprocate at the same time to drive the mounting frame 5 to reciprocate, so as to drive the cutter 6 to reciprocate. When the gear teeth of the intermittent gear 21 are aligned with the driven gear, the gear teeth of the intermittent gear 21 are aligned with the driven gear. When the wheels 20 mesh with each other and rotate, the driven gear 20 is driven to rotate, and the driven gear 20 rotates to drive the roller 4 to rotate, so that multiple pieces of rubber 3 can be driven to be transported. When multiple pieces of rubber 3 are transported, the roller 4 above is driven to rotate. When the gear teeth of the intermittent gear 21 are disengaged from the driven gear 20, the driven gear 20 stops rotating, so that the roller 4 stops rotating. The roller 4 stops rotating and the multiple pieces of rubber 3 are stopped from being transported. The above operation is repeated, so that multiple pieces of rubber 3 can be driven to be transported intermittently. When the cutter 6 moves downward to shear the rubber 3, the gear teeth of the intermittent gear 21 are disengaged from the driven gear 20, so that the multiple pieces of rubber 3 are stopped from being transported, and the rubber 3 is cut into strips under the action of the shear block 7. When the cutter 6 moves upward to reset, the gear teeth of the intermittent gear 21 mesh with the driven gear 20, so that multiple pieces of rubber 3 are transported. The above operation is repeated, and the rubber 3 can be cut into strips uninterruptedly.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications of the above assumptions should also be regarded as the protection scope of the present invention.
