Description

Technical Field

[0001] This utility model relates to the field of rubber processing and collection technology, and in particular to an automatic rubber and plastic strip cutting machine with automatic loading and unloading. Background Technology

[0002] A rubber strip cutter is a specialized cutting device for rubber materials. It can cut large rubber sheets, rubber rolls, or vulcanized rubber products into strips of uniform length and width, and is widely used in applications such as seals, buffer strips, and door and window sealing strips.

[0003] A Chinese utility model patent with authorization announcement number CN211891138U discloses an adjustable rubber strip cutting machine, characterized by: a cutting machine body, a feeding trough on one side of the upper part of the cutting machine body, side plates on both sides of the upper part of the cutting machine body, a rotating wheel and a transmission device between the side plates, a second motor on one side of the side plate located on the rotating wheel and the transmission device, a second cutter on the upper part of the cutting machine body located below the transmission device, an adjustment structure and a conveying roller on the feeding trough, a discharge trough on one side of the cutting machine body located away from the adjustment structure, and a material collection device on the cutting machine body located at the discharge trough.

[0004] However, although the material collection device of the rubber strip cutting machine in the above patent uses an inclined plate to make the strips slide down, the inclined plate can only achieve simple guidance of the strips to fall down, and cannot constrain the stacking state of the strips. As a result, the strips are prone to pile up messily due to gravity impact and mutual collision during the sliding process, and still need to be sorted manually, which makes it difficult to meet the high-efficiency production needs of direct removal. Utility Model Content

[0005] The purpose of this invention is to provide an automatic rubber and plastic strip cutting machine with automatic loading and unloading, which effectively collects and organizes the cut strips and improves efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automatic loading and unloading rubber and plastic strip cutting machine, including a strip cutting mechanism, a feeding mechanism for discharging material is provided on one side of the strip cutting mechanism, a collecting mechanism for collecting material is provided on one side of the feeding mechanism, the collecting mechanism includes a collecting bin and two movable adjustable side plates, the movement directions of the two adjustable side plates are perpendicular to each other, and a straightening mechanism is provided on the collecting mechanism, the straightening mechanism controls the two adjustable side plates to move closer or further away at the same time.

[0007] By adopting the above technical solution, the rubber strips cut by the cutting mechanism are conveyed to the collection bin of the collection mechanism by the feeding mechanism. As they fall in one by one, they are stacked in a staggered manner. The two adjusting side plates with mutually perpendicular movement directions in the collection mechanism are pushed and adjusted by the straightening mechanism through multiple approaches and movements. After the strips are neatly aligned, the adjusting side plates are moved away to facilitate removal. This realizes the automated process of rubber and plastic strips from processing and collection to automatic straightening, improving the overall processing efficiency and convenience.

[0008] A further configuration of this utility model is as follows: the regulating mechanism includes a linkage assembly and a reciprocating assembly. The linkage assembly includes a slide rod, a secondary driven rod, and a reversing assembly. The slide rod includes a driving part and a driven part. The driving part and the driven part are arranged in the same direction and connected to each other. The driving part is fixedly connected to the outer side of the adjusting side plate. The secondary driven rod is fixedly connected to the outer side of another adjusting side plate. The driven part is connected to the secondary driven rod through the reversing assembly. The reciprocating assembly drives the driving part to reciprocate.

[0009] By adopting the above technical solution, when the reciprocating component drives the drive unit of the slide bar, the adjusting side plate connected to the drive unit moves closer to or further away from the cutting strip. At the same time, the driven part drives the secondary driven rod synchronously through the reversing component, so that the other adjusting side plate moves in the vertical direction in sync with the movement of the first adjusting side plate, and moves closer to or further away from the cutting strip. The two adjusting side plates move closer to or further away from each other multiple times at the same time, pushing and adjusting the cutting strip in the collection bin until it is neatly aligned, thereby improving the degree of automation and efficiency.

[0010] A further feature of this invention is that the reversing assembly includes an L-shaped slide groove, a connecting rod is provided on the L-shaped slide groove, the secondary driven rod and the driven part are vertically arranged and slidably connected on the L-shaped slide groove, and the secondary driven rod and the driven part are hinged through the connecting rod.

[0011] By adopting the above technical solution, when the driven part moves, the secondary driven rod is driven to slide along the L-shaped groove through the first connecting rod, thereby realizing the vertical reversal of the motion direction.

[0012] A further feature of this invention is that a crankshaft and a crank are provided at the right angle of the L-shaped groove, one end of the crank is hinged to the crankshaft, and the other end is hinged to the middle of the connecting rod.

[0013] By adopting the above technical solution, the crank provides a fulcrum and guide for the movement of connecting rod one through its own rotation around the crankshaft, enhances the stability of the power transmission of connecting rod one, ensures the accuracy of the trajectory of the secondary driven rod when sliding along the L-shaped groove, and helps to improve the reliability of vertical reversal of the motion direction.

[0014] A further feature of this invention is that the reciprocating assembly includes a drive motor, a turntable, and a second connecting rod. The second connecting rod is eccentrically mounted on the turntable. One end of the second connecting rod is hinged to the turntable, and the other end is hinged to the slide rod. A guide block is provided between the turntable and the adjusting side plate. A guide groove is provided on the guide block. The slide rod is slidably connected in the guide groove. The turntable is coaxially and fixedly connected to the output end of the drive motor.

[0015] By adopting the above technical solution, the drive motor drives the coaxially fixed turntable to rotate, and the eccentrically hinged connecting rod 2 on the turntable rotates eccentrically accordingly. Due to the restriction of the guide groove on the guide block, the slide rod hinged to the other end of the connecting rod 2 can only move in a straight line along the guide groove, thereby converting the rotational motion of the turntable into the reciprocating linear motion of the slide rod.

[0016] A further feature of this invention is that the collecting mechanism includes a base plate and two reference side plates, the reference side plates being movably connected to the adjusting side plate, and the base plate being fixedly connected to the two reference side plates.

[0017] By adopting the above technical solution, the base plate is fixedly connected to the two reference side plates to form the basic frame for collection. The two adjustable side plates are movably connected to the reference side plates and move based on the reference side plates. Together, they form an adjustable collection space, providing stable structural support for the collection and straightening of the strips.

[0018] A further feature of this invention is that the feeding mechanism includes a conveying component, an inclined slider is provided at the end of the conveying component, the inclined slider is fixedly connected to the conveying component, and guide plates are provided on both sides of the inclined slider, the guide plates being vertically fixedly connected to the inclined slider.

[0019] By adopting the above technical solution, after the conveying component delivers the cut strip to the end, the cut strip enters the inclined slider that is fixed thereto. The guide plates fixed vertically on both sides of the inclined slider restrict the deviation of the cut strip, so that the cut strip slides smoothly down along the inclined direction and smoothly enters the collection mechanism.

[0020] A further feature of this invention is that the conveying assembly includes a conveyor belt, a conveyor motor, and a support platform. The support platform is located on one side of the conveyor belt, and the conveyor motor is fixedly mounted on the support platform. The conveyor motor controls the movement of the conveyor belt.

[0021] By adopting the above technical solution, a conveyor motor fixed on one side of the support platform provides power to control the movement of the conveyor belt set inside and above the support platform, and the conveyor belt operation realizes the conveying of the cut strips.

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

[0023] 1. The rubber strips cut by the cutting mechanism are conveyed to the collection bin of the collection mechanism by the feeding mechanism. As they fall in one by one, they are stacked in a staggered manner. The two adjusting side plates in the collection mechanism, which move perpendicularly to each other, are pushed and adjusted by the straightening mechanism through multiple approaches and movements. After the strips are neatly aligned, the adjusting side plates are moved away to facilitate removal. This realizes the automated process of rubber and plastic strips from processing and collection to automatic straightening, improving the overall processing efficiency and convenience.

[0024] 2. When the reciprocating assembly drives the sliding rod to move, the adjusting side plate connected to the drive unit moves closer to or further away from the cutting strip. At the same time, the driven part drives the secondary driven rod synchronously through the reversing assembly, so that the other adjusting side plate moves in the vertical direction in sync with the movement of the first adjusting side plate, and moves closer to or further away from the cutting strip. The two adjusting side plates move closer to or further away from each other multiple times at the same time, pushing and adjusting the cutting strip in the collection bin until it is neatly aligned, thus improving the degree of automation and efficiency.

[0025] 3. When the driven part moves, it drives the secondary driven rod to slide along the L-shaped groove through the first connecting rod, thereby realizing the vertical reversal of the motion direction; the crank provides a fulcrum and guide for the motion of the first connecting rod by rotating around the crankshaft, enhancing the stability of the power transmission of the first connecting rod, ensuring the accuracy of the trajectory of the secondary driven rod when sliding along the L-shaped groove, and helping to improve the reliability of the vertical reversal of the motion direction.

[0026] 4. The base plate is fixedly connected to the two reference side plates to form the basic frame for collection. The two adjustable side plates are movably connected to the reference side plates and move based on the reference side plates. Together they form an adjustable collection space, providing stable structural support for the collection and straightening of the strips. Attached Figure Description

[0034] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0035] like Figure 1-5 As shown, an automatic rubber and plastic strip cutting machine includes a cutting mechanism 1, a feeding mechanism 2 for discharging material on one side of the cutting mechanism 1, and a collecting mechanism 3 for collecting material on one side of the feeding mechanism 2. The collecting mechanism 3 includes a collecting bin 31 and two movable adjusting side plates 32. The movement directions of the two adjusting side plates 32 are perpendicular to each other. A straightening mechanism 4 is provided on the collecting mechanism 3, which controls the two adjusting side plates 32 to move closer or further away simultaneously. Chinese utility model patent with authorization announcement number CN207630119U discloses a rubber strip cutting machine that uses a longitudinal cutting device and a transverse cutting device. The cutting device is used in conjunction with the rubber block to cut the rubber block into small rectangular pieces in the longitudinal and transverse directions. When the rubber and plastic cutting machine of this application with automatic loading and unloading is working, the rubber strips formed by the cutting mechanism 1 cutting the raw material are conveyed to the collection bin 31 of the collection mechanism 3 by the unloading mechanism 2. The strips fall into the bin one by one and form a staggered stack. At this time, the straightening mechanism 4 on the collection mechanism 3 is activated, which drives the two adjusting side plates 32 with mutually perpendicular movement directions in the bin to move closer or further away from each other. Through multiple pushing, the strips are adjusted to a neat state. Then the adjusting side plates 32 are moved away to facilitate the removal of the strips, thus completing the automated operation from cutting, collection to straightening.

[0036] The regulating mechanism 4 includes a linkage assembly 5 and a reciprocating assembly 6. The linkage assembly 5 includes a slide rod 51, a secondary driven rod 52, and a reversing assembly 7. The slide rod 51 includes a driving part 511 and a driven part 512. The driving part 511 and the driven part 512 are arranged in the same direction and connected to each other. The driving part 511 is fixedly connected to the outside of the adjusting side plate 32. The secondary driven rod 52 is fixedly connected to the outside of another adjusting side plate 32. The driven part 512 is connected to the secondary driven rod 52 through the reversing assembly 7. The reciprocating assembly... 6 drives the drive unit 511 to reciprocate; the reciprocating assembly 6 drives the drive unit 511 of the slide bar 51 to reciprocate, causing the adjusting side plate 32 connected to the drive unit 511 to move closer to or away from the cutting strip. The drive unit 511 synchronously drives the driven unit 512, and after the direction is changed by the reversing assembly 7, it synchronously drives the secondary driven rod 52, so that the other adjusting side plate 32 moves synchronously in the vertical direction. The two adjusting side plates 32 push the cutting strip in the collection chamber 31 through multiple synchronous reciprocating movements, thus adjusting and aligning the cutting strip.

[0037] The reversing assembly 7 includes an L-shaped slide groove 71, on which a connecting rod 72 is mounted. A secondary driven rod 52 and a driven part 512 are vertically mounted and slidably connected to the L-shaped slide groove 71. The secondary driven rod 52 and the driven part 512 are hinged together via the connecting rod 72. A crankshaft 73 and a crank 74 are mounted at the right angle of the L-shaped slide groove 71. One end of the crank 74 is hinged to the crankshaft 73, and the other end is hinged to the middle of the connecting rod 72. The right angle of the L-shaped slide groove 71... A crankshaft 73 is fixedly installed. When the driven part 512 slides along the L-shaped slide groove 71, it drives the secondary driven rod 52 through the connecting rod 72. When the connecting rod 72 moves, the crank 74, which is hinged in the middle, rotates around the crankshaft 73 as the rotation center, which constrains and guides the direction of the connecting rod 72. Under the cooperative action of the connecting rod 72 and the crank 74, the secondary driven rod 52 slides along the L-shaped slide groove 71 perpendicular to the driven part 512, realizing the change of motion direction and transmitting power.

[0038] The reciprocating assembly 6 includes a drive motor 61, a turntable 62, and a second connecting rod 63. The second connecting rod 63 is eccentrically mounted on the turntable 62. One end of the second connecting rod 63 is hinged to the turntable 62, and the other end is hinged to the slide rod 51. A guide block 64 is provided between the turntable 62 and the adjusting side plate 32. A guide groove 65 is provided on the guide block 64. The slide rod 51 is slidably connected in the guide groove 65. The turntable 62 is coaxially and fixedly connected to the output end of the drive motor 61. When the reciprocating assembly 6 is working, the drive motor 61 starts, and its output end drives the coaxially fixed turntable 62 to rotate. The second connecting rod 63, which is eccentrically hinged on the turntable 62, rotates eccentrically, pushing the slide rod 51, which is hinged at the other end, to move. The slide rod is restricted by the guide groove 65 on the guide block 64, and the slide rod 51, which is hinged to the other end of the second connecting rod 63, performs a reciprocating linear motion along the guide groove 65. This reciprocating motion is transmitted to the subsequent components through the slide rod 51 to drive the adjusting side plate 32.

[0039] The collection mechanism 3 also includes a base plate 33 and two reference side plates 34. The reference side plates 34 are movably connected to the adjusting side plates 32, and the base plate 33 is fixedly connected to the two reference side plates 34. When the collection mechanism 3 is working, the base plate 33 and the two reference side plates 34 are fixedly connected to form a collection chamber 31 frame, providing stable support for the stacking of cut strips. The adjusting side plates 32, which are movably connected to the reference side plates 34, move closer to or further away from the cut strips under the drive of relevant components. When the cut strips fall in, the reference side plates 34 and the adjusting side plates 32 are initially limited. During the alignment stage, the adjusting side plates 32 use the reference side plates 34 as a reference and push in the vertical direction to adjust the misaligned cut strips to alignment, achieving neat storage.

[0040] The feeding mechanism 2 includes a conveying component 8. An inclined slider 21 is provided at the end of the conveying component 8. The inclined slider 21 is fixedly connected to the conveying component 8. Guide plates 22 are provided on both sides of the inclined slider 21. The guide plates 22 are vertically fixedly connected to the inclined slider 21. The conveying component 8 includes a conveyor belt 81, a conveyor motor 82, and a support platform 83. The support platform 83 is located on one side of the conveyor belt 81. The conveyor motor 82 is fixedly mounted on the support platform 83 and controls the movement of the conveyor belt 81. When the feeding mechanism 2 is working, the conveyor motor 82 on the support platform 83 drives the conveyor belt 81 to rotate. The cut strips are conveyed to the inclined slider 21 at the end via the conveyor belt 81. The guide plates 22 fixed vertically on both sides of the inclined slider 21 play a limiting and guiding role for the cut strips during conveying. Finally, the cut strips slide into the collection bin 31 via the inclined slider 21.

[0041] The working process of this utility model of an automatic loading and unloading rubber and plastic strip cutting machine is as follows:

[0042] S1. The rubber raw material is laid flat on the feeding table, and the cutting mechanism 1 cuts the raw material to form a row of square rubber strips, which then fall onto the conveyor belt 81 below.

[0043] S2. Start the conveyor motor 82. The conveyor belt 81 runs under the drive of the motor. Each piece of rubber strip is conveyed sequentially by the conveyor belt 81 to the inclined slider 21 at the end, and then slides into the collection mechanism 3 through the inclined slider 21.

[0044] S3. Start the drive motor 61 to drive the turntable 62 to rotate. The connecting rod 63 on the turntable 62 moves eccentrically in a circular motion with the turntable 62, which in turn drives the slide rod 51 to reciprocate along the guide groove 65.

[0045] S4. The drive part 511 of the slide rod 51 moves, and the driven part 512 moves in sync with it. The secondary driven rod 52 is pushed or pulled by the connecting rod 72. During this process, the sliding of the driven part 512 drives the connecting rod 72 to rotate around the crank 74, so that the secondary driven rod 52 slides along the other direction of the L-shaped slide groove 71, thereby realizing the change of motion direction.

[0046] S5. Therefore, after the drive motor 61 starts, it will indirectly drive the drive part 511 of the slide bar 51 and the secondary driven rod 52 to reciprocate synchronously. The two adjustment side plates 32 connected to it will reciprocate accordingly, continuously pushing the misaligned rubber strips stacked in the collection mechanism 3, and finally arranging them into a neat stacked shape with the top and bottom aligned and the edges and corners collinear, which is convenient for subsequent removal and bundling.
