Description

Technical Field

[0001] The utility model relates to the technical field of weighing equipment, in particular to a rubber cutting weighing device. Background Art

[0002] The processing of rubber products requires the use of various equipment, including rubber mixers, calenders, extruders, molding machines, and vulcanizers. The selection and use of these equipment have a significant impact on the quality and production efficiency of rubber products. The rubber mixer is used to mix raw rubber and compounding ingredients to ensure a uniform blend. When the raw rubber is fed into the mixer, a conveyor is required to transport the rectangular blocks of raw rubber to the mixer. Since the weight of each block of raw rubber is fixed, in order to improve the ratio of raw materials, the last block of raw rubber transported is usually weighed to obtain an accurate ratio of raw rubber to compounding ingredients.

[0003] Regarding the above-mentioned related technologies, the inventors found that workers usually cut the last piece of raw rubber into pieces first, and then use weighing equipment to weigh the cut raw rubber to calculate the weight of the missing raw rubber. Since there is a large error between the cut raw rubber and the expected weight of the raw rubber, it is necessary to repeat the above-mentioned cutting and weighing actions many times to obtain a relatively accurate weight of the raw rubber. This operation method increases the labor intensity of the workers and reduces work efficiency. Utility Model Content

[0004] The main technical problem solved by the utility model is to provide a rubber cutting weighing device, which reduces the labor intensity of workers and improves work efficiency.

[0005] To solve the above technical problems, the present invention adopts a technical solution: providing a rubber cutting and weighing device, comprising: two roller-type transmission frame assemblies connected in abutting relation, a U-shaped mounting frame being provided above the left roller-type transmission frame assembly, a cutter being provided in the inner cavity of the U-shaped mounting frame, a first driving mechanism for driving the cutter to rise and fall being connected to the U-shaped mounting frame, a telescopic limit plate assembly being provided on one side of the cutter, and a second driving mechanism for driving the telescopic limit plate assembly to rise and fall being connected to one side of the U-shaped mounting frame;

[0006] Two linear guide roller assemblies fixed to the roller-type transmission frame assembly are symmetrically provided on the other side of the cutter, and the gap between the linear guide roller assemblies can be adjusted;

[0007] It also includes a lifting type weighing support frame assembly that can pass through the roller type transmission frame assembly on the left.

[0008] By adopting the above technical solution, when in use, several pieces of raw rubber are placed on the roller conveyor frame assembly in turn and conveyed to the rubber mixer for mixing with the compounding agent. Since the weight accuracy requirement of the raw rubber is relatively high, the roller conveyor frame assembly on the left is operated to transport the last piece of raw rubber to the bottom of the cutter. The rectangular block of raw rubber is located between the linear guide roller assemblies, so that the side of the raw rubber is relatively parallel to the conveying direction of the roller conveyor frame assembly. The first driving mechanism is operated to drive the cutter to move downward a certain distance. It is visually observed that the raw rubber to be cut is obviously smaller than the actual required weight. The first driving mechanism is continued to be operated to drive the cutter to cut the raw rubber. The left roller conveyor frame assembly is operated to transfer the cut raw rubber to the top of the lifting weighing support frame assembly. The lifting weighing support frame assembly is operated to drive the raw rubber to separate from the roller conveyor frame assembly and weigh its weight. The lifting weighing support frame assembly is then operated to drive the raw rubber to fall on the roller conveyor frame assembly, and the roller conveyor frame assembly drives the raw rubber block to the roller conveyor frame assembly on the right. The conveying frame assembly moves so that the cut raw rubber material is located on the right roller conveying frame assembly. The weight and length of the raw rubber material in the entire rectangular block can be calculated to obtain the length corresponding to each kilogram of raw rubber material, and the length corresponding to the weight of the missing raw rubber material can be calculated. The second driving mechanism is operated to drive the telescopic limiting plate assembly to move downward a certain distance, and then the telescopic limiting plate assembly is operated to make the distance between its limiting surface and the blade of the cutter equal to the length corresponding to the missing raw rubber material. The left roller conveying frame assembly is operated to drive the raw rubber material to be transmitted to the telescopic limiting plate assembly. The raw rubber material stops after contacting the limiting surface of the telescopic limiting plate assembly. The first driving mechanism is operated to drive the cutter to cut the raw rubber material. The cut raw rubber material is transmitted to the roller conveying frame assembly on the right via the left roller conveying frame assembly. Finally, the right roller conveying frame assembly transmits the raw rubber material to the rubber mixing mill. There is no need for workers to repeat the cutting, weighing and other actions of the raw rubber material many times, which reduces the labor intensity of workers and improves work efficiency.

[0009] In a preferred example, the present invention can be further configured as follows: the first driving mechanism includes a cylinder and a moving rod arranged in a U-shaped mounting frame, the lower plane of the moving rod is provided with a mounting groove, the mounting groove is connected to the cutting knife, the inner walls on both sides of the U-shaped mounting frame are respectively connected to U-shaped guide grooves, the U-shaped guide grooves are respectively slidably connected to T-shaped sliders, and the T-shaped sliders are connected to the ends of the moving rod.

[0010] By adopting the above technical solution, the telescopic rod of the oil cylinder extends and contracts, thereby driving the cutter on the movable rod to move in the vertical direction. The T-shaped sliders at both ends of the movable rod slide in the corresponding U-shaped guide grooves, thereby enhancing the stability of the cutter when cutting the raw rubber material.

[0011] In a preferred example, the present invention can be further configured as follows: the telescopic limit plate assembly includes an L-shaped plate and a transverse electric push rod installed on the L-shaped plate, the extended end of the transverse electric push rod is connected to the limit plate body, and after the telescopic rod of the transverse electric push rod is fully extended, the side of the limit plate body away from the transverse electric push rod coincides with the blade of the cutter in the horizontal direction.

[0012] By adopting the above technical solution, the length corresponding to the missing raw rubber material is calculated, and the telescopic rod of the horizontal electric push rod is operated to retract. The horizontal electric push rod drives the limit plate to move a distance equal to the length corresponding to the missing raw rubber material, and the limit plate limits the end of the raw rubber material relatively accurately.

[0013] In a preferred example, the present invention can be further configured as follows: the second driving mechanism includes a transverse plate and a vertical electric push rod installed on the transverse plate, the protruding end of the vertical electric push rod is connected to a lifting rod, the two ends of the lifting rod are respectively connected to vertical guide rails, the vertical guide rails are connected to a U-shaped mounting frame, and the lifting rod is connected to the L-shaped plate.

[0014] By adopting the above technical solution, the telescopic rod of the vertical electric push rod extends and retracts, thereby driving the telescopic limit plate assembly to move in the vertical direction. Since the two ends of the lifting rod are respectively connected to the U-shaped mounting frame through vertical guide rails, the stability of the telescopic limit plate assembly during movement and limiting is enhanced.

[0015] In a preferred example, the present invention can be further configured as follows: the linear guide roller assembly includes a U-shaped seat and a plurality of guide roller bodies rotatably connected to its inner cavity at intervals, and also includes a horizontal driving member, the horizontal driving member includes a vertical mounting plate fixed on the roller-type transmission frame assembly, a horizontal electric push rod is connected to the vertical mounting plate, the protruding end of the horizontal electric push rod is connected to the U-shaped seat, and horizontal guide rods are respectively provided on both sides of the horizontal electric push rods mounted on the vertical mounting plate, and one end of the horizontal guide rod is connected to the U-shaped seat.

[0016] By adopting the above technical solution, the last piece of raw rubber is placed on the left roller-type conveyor frame assembly, and the telescopic rod of the horizontal electric push rod is operated to extend, thereby driving the guide roller body on the U-shaped seat to contact the side of the rectangular block of raw rubber, so that the side of the raw rubber is relatively parallel to the conveying direction of the roller-type conveyor frame assembly, thereby enhancing the weight accuracy of the cutter in cutting the raw rubber.

[0017] In a preferred example, the present invention can be further configured as follows: the lifting weighing support frame assembly includes a fixed plate and several support plates connected to the fixed plate at intervals, a transition plate is provided below the fixed plate, a gravity sensor is connected between the transition plate and the fixed plate, a plurality of strip plates are embedded in the upper end of the support plate, and also includes a vertical lifting member, the vertical lifting member includes a U-shaped support plate body connected to the roller-type transmission frame assembly, a yielding electric push rod is installed on the U-shaped support plate body, the protruding end of the yielding electric push rod is connected to the transition plate, and vertical guide rods are respectively provided on both sides of the yielding electric push rod and are passed through the U-shaped support plate body, and the upper end of the vertical guide rod is connected to the transition plate.

[0018] By adopting the above technical solution, the telescopic rod of the electric push rod is extended, thereby driving the transition plate, gravity sensor, fixed plate and support plate to move upward, thereby driving the raw rubber material to separate from the roller-type transmission frame assembly. The gravity sensor can measure the weight of the raw rubber material. The structure is simple and the operation is convenient.

[0019] In a preferred example, the present invention can be further configured as follows: the roller-type transmission frame assembly includes a transmission frame body and a plurality of electric rollers rotatably connected to its inner cavity at intervals, and the outer circles of the electric rollers located below the strip plates are respectively provided with annular clearance grooves equal in number to the strip plates.

[0020] By adopting the above technical solution, after the electric drum is connected to the power supply, the electric drum can drive the raw rubber material to be transported by self-rotation. After the strip plate is located in the annular groove, the upper plane of the annular groove is lower than the outer circular top of the electric drum.

[0021] In summary, the present invention has at least one of the following beneficial technical effects:

[0022] The weight and length of the entire rectangular block of raw rubber can be calculated to obtain the length corresponding to each kilogram of raw rubber, and the length corresponding to the weight of the missing raw rubber can be calculated.
