Description

Technical Field

[0001] This invention relates to the field of material spreading devices, specifically a uniform material spreading device for a sheet machine used in the production of plastic pallets. Background Technology

[0002] With the rapid development of the logistics industry, the demand for plastic pallets, as an important tool in logistics warehousing, has increased significantly. Compared with traditional wooden pallets, plastic pallets have many advantages such as corrosion resistance, long service life, and hygiene. In the production process of plastic pallets, the quality of the sheet material is crucial, as it directly affects the performance and quality of the pallet.

[0003] Patent CN213864494U relates to a uniform material spreading device for a sheet machine in plastic pallet production. The technical solution includes a housing with a roller inside. Multiple partition plates are fixedly connected to the outer periphery of the roller, arranged in a uniform circumferential array. Rotary rods are fixedly connected to both ends of the roller, with two rods passing through and rotatably connected to the housing. A second gear is fixedly connected to the end of each of the two rods away from the roller. The beneficial effect of this uniform material spreading device for a sheet machine in plastic pallet production is that by setting multiple partition plates, it can uniformly spread the material... The material is evenly divided into several portions, and then the rollers rotate to feed the material onto the conveyor belt one by one, ensuring even feeding. At the same time, the height of the baffle can be adjusted by rotating the threaded rod. This device allows the operator to adjust the feeding height of the material as needed to adapt to the production rhythm of the sheet machine and speed up production efficiency. However, when using this device, it is prone to adding too much plastic granules and unevenly, which can easily cause the plastic granules to overflow outside the baffle and thus waste the plastic granules. Therefore, a uniform feeding device for sheet machines in plastic pallet production is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a uniform material spreading device for a sheet machine for producing plastic pallets, which addresses the shortcomings of the prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a uniform material spreading device for a sheet machine in plastic pallet production, comprising a support leg, a conveyor table installed on the inner wall of the support leg, a mold set on the top of the conveyor table, a fixed plate two fixedly connected to the rear of the support leg, a discharge device set on the right side of the support leg, a stirring device set on the inner wall of the discharge device, and a clamping device set on the inner wall of the support leg. The discharge device includes a lead screw, a sliding block, a housing, a rotating shaft, a transmission wheel, a limiting roller, a motor, a pulley set one, a transmission belt, a pulley set two, and an arc plate. The lead screw is rotatably connected to the inner wall of the support leg, the sliding block is movably connected to the circumferential surface of the lead screw, the housing is fixedly connected to the right side of the sliding block, the rotating shaft is rotatably connected to the inner wall of the housing, the transmission wheel one is fixedly connected to the circumferential surface of the rotating shaft, the limiting roller is fixedly connected to the circumferential surface of the rotating shaft, the motor is fixedly connected to the top of the fixed plate two, and the pulley set one is fixedly connected to the motor. At the output end, the transmission belt is connected to the outer wall of the first pulley group, the second pulley group is fixedly connected to the circumferential surface of the first lead screw, the arc plate is fixedly connected to the front of the outer shell, the right side of the first transmission wheel is fixedly connected to the left side of the limiting roller, the left side of the first transmission wheel is in contact with the inner wall of the outer shell, the circumferential surface of the limiting roller is in contact with the inner wall of the outer shell, the inner wall of the transmission belt is connected to the outer wall of the second pulley group, and the bottom of the arc plate is in contact with the top of the mold. When the material is laid, the plastic mold conveyor moves to the designated feeding position, and then the worker adds various plastic granules into the outer shell. The rotating shaft rotates, driving the limiting roller to rotate, thereby limiting the outflow of plastic granules and preventing them from flowing out too quickly, making the material output more uniform and preventing uneven spreading of plastic granules in the mold. At the same time, when the arc plate moves, it can scrape off excess plastic granules on the surface of the mold, thereby avoiding waste of plastic granules and allowing excess plastic granules to be recycled and reused.

[0006] Preferably, the stirring device includes a second lead screw, a second transmission wheel, a first fixed plate, a limiting plate, a sliding plate, and a fixed rod. The second lead screw is rotatably connected to the inner wall of the outer casing. The second transmission wheel is fixedly connected to the circumferential surface of the second lead screw. The first fixed plate is fixedly connected to the inner wall of the outer casing. The limiting plate is fixedly connected to the surface of the first fixed plate. The sliding plate is movably connected to the circumferential surface of the second lead screw. The fixed rod is fixedly connected to the top of the sliding plate. The stirring device also includes a third transmission wheel, a first agitating plate, a connecting rod, a fourth transmission wheel, a second agitating plate, and a protrusion. The third transmission wheel is rotatably connected to the circumferential surface of the fixed rod. The first agitating plate is fixedly connected to the top of the third transmission wheel. The connecting rod is rotatably connected to the surface of the fixed rod. The fourth transmission wheel is rotatably connected to the end of the connecting rod away from the fixed rod. The second agitating plate is fixedly connected to the fourth transmission wheel. On the surface, the protrusion is fixedly connected to the inner wall of the outer shell. The circumferential surface of the second transmission wheel is in contact with the circumferential surface of the first transmission wheel. The inner wall of the outer shell is in contact with the circumferential surface of the third transmission wheel. The inner wall of the limiting plate is in contact with the surface of the sliding plate. The circumferential surface of the fourth transmission wheel is in contact with the inner wall of the outer shell. During material spreading, the various plastic particles introduced into the outer shell can be stirred, so that the various plastic particles can be mixed more evenly. This improves the quality of the plastic pallets produced in subsequent processing and increases the stirring effect of the plastic particles, making the plastic particles more evenly stirred. The fourth transmission wheel generates a knocking vibration on the outer shell, which can shake off the plastic particles attached to the inner wall of the outer shell, thereby increasing the utilization rate of the plastic particles and keeping the inside of the device clean when the device is not in use.

[0007] Preferably, the clamping device includes a fixed block, a clamping plate, a transmission spring, an inclined block, a collecting box, a push block, an L-shaped plate, and a push plate. The fixed block is fixedly connected to the inner wall of the support leg, the clamping plate is slidably connected to the inner wall of the fixed block, the transmission spring is installed between the clamping plate and the fixed block, the inclined block is fixedly connected to the front of the arc-shaped plate, the collecting box is installed on the right side of the support leg, the push block is fixedly connected to the inner wall of the arc-shaped plate, the push plate is rotatably connected to the inner wall of the collecting box via a torsion spring, the L-shaped plate is fixedly connected to the rear of the push plate, and the left side of the inclined block is connected to the inner wall of the collecting box. The right sides of the clamping plates are in contact with each other, the rear of the pusher block is in contact with the front of the L-shaped plate, and the top of the inner wall of the collection box is in contact with the bottom of the pusher plate. This allows for the correction and clamping of the mold on the conveyor table, preventing inaccurate placement of the mold and subsequent inaccurate spreading of plastic granules, which would lead to waste of plastic granules and affect the effectiveness of the device. At the same time, the collected plastic granules can be agitated to prevent them from accumulating on the right side of the collection box, increasing the capacity of the collection box and preventing excessive accumulation of plastic granules that could cause them to overflow.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0009] 1. This sheet material spreading device for plastic pallet production utilizes the coordinated operation of support legs, a conveyor table, a mold, a discharge device, a lead screw, a sliding block, a housing, a rotating shaft, a transmission wheel, a limiting roller, a motor, a pulley set, a transmission belt, a pulley set, and an arc-shaped plate. When spreading begins, the plastic mold conveyor table moves to the designated feeding position. Then, the worker adds various plastic granules into the housing. The rotating shaft rotates, driving the limiting roller to rotate, thus restricting the outflow of plastic granules and preventing them from flowing out too quickly. This ensures more uniform material distribution and prevents uneven spreading of plastic granules in the mold. Simultaneously, as the arc-shaped plate moves, it scrapes off excess plastic granules from the mold surface, preventing waste and allowing excess granules to be recycled and reused.

[0010] 2. This sheet material spreading device for plastic pallet production utilizes the coordinated operation of a mixing device, lead screw two, transmission wheel two, fixed plate one, limit plate, sliding plate, fixed rod, transmission wheel three, stirring plate one, connecting rod, transmission wheel four, stirring plate two, and protrusions. During spreading, it agitates the various plastic granules introduced into the outer shell, ensuring more uniform mixing and improving the quality of the plastic pallets produced in subsequent processing. It also enhances the mixing effect, resulting in more even agitation of the plastic granules. The transmission wheel four vibrates against the outer shell, shaking off plastic granules adhering to the inner wall of the shell, increasing the utilization rate of the plastic granules. Furthermore, it maintains the cleanliness of the device's interior at the end of its operation.

[0011] 3. The uniform material spreading device for the sheet material production of this plastic pallet uses the coordinated operation of a fixed block, clamping plate, transmission spring, inclined block, collection box, push block, L-shaped plate, push plate, and fixed plate to correct and clamp the mold on the conveyor table. This prevents inaccurate placement of the mold, which would lead to inaccurate spreading of subsequent plastic granules, resulting in waste of plastic granules and affecting the effectiveness of the device. At the same time, it can agitate the collected plastic granules to prevent them from accumulating on the right side of the collection box, increasing the capacity of the collection box and preventing excessive accumulation of plastic granules that could cause overflow.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-9One embodiment of the present invention is: a sheet material spreading device for plastic pallet production, comprising a support leg 1, a conveyor table 2 installed on the inner wall of the support leg 1, a mold 3 provided on the top of the conveyor table 2, and a fixing plate 7 fixedly connected to the rear of the support leg 1; a discharge device 4 is provided on the right side of the support leg 1, a stirring device 5 is provided on the inner wall of the discharge device 4, and a clamping device 6 is provided on the inner wall of the support leg 1; the discharge device 4 includes a lead screw 41, a sliding block 42, a housing 43, a rotating shaft 44, a transmission wheel 45, a limiting roller 46, a motor 47, a pulley set 48, a transmission belt 49, a pulley set 410, and an arc plate 411, the lead screw 41 being rotatably connected to the support leg 1. The inner wall of leg 1 has a sliding block 42 movably connected to the circumferential surface of lead screw 41. The outer shell 43 is fixedly connected to the right side of the sliding block 42. A rotating shaft 44 is rotatably connected to the inner wall of the outer shell 43. A transmission wheel 45 is fixedly connected to the circumferential surface of the rotating shaft 44. A limiting roller 46 is fixedly connected to the circumferential surface of the rotating shaft 44. When material feeding begins, the plastic mold 3 conveyor table 2 moves to the designated feeding position. Then, the worker adds various plastic granules into the outer shell 43. At this time, the motor 47 starts, driving lead screw 41 to rotate. The rotation of lead screw 41 causes sliding block 42 to move, which in turn causes the outer shell 43 to move. The movement of the outer shell 43 then causes the rotating shaft 44 to move. The movement of shaft 44 drives the first transmission wheel 45 to move. After moving a certain distance, the first transmission wheel 45 contacts the top of mold 3, causing it to rotate due to friction with mold 3. The rotation of the first transmission wheel 45 drives the rotating shaft 44 to rotate, which in turn drives the limiting roller 46 to rotate. This restricts the flow of plastic granules, preventing them from flowing out too quickly and ensuring more uniform discharge. This prevents uneven distribution of plastic granules in mold 3. Motor 47 is fixedly connected to the top of fixed plate 7. Pulley group 48 is fixedly connected to the output end of motor 47. Transmission belt 49 is connected to the outer wall of pulley group 48. Pulley group 410 is fixedly connected to... On the circumferential surface of the lead screw 41, the arc plate 411 is fixedly connected to the front of the outer shell 43. The right side of the transmission wheel 45 is fixedly connected to the left side of the limiting roller 46. The left side of the transmission wheel 45 is in contact with the inner wall of the outer shell 43. The circumferential surface of the limiting roller 46 is in contact with the inner wall of the outer shell 43. The inner wall of the transmission belt 49 is connected to the outer wall of the pulley group 410. The bottom of the arc plate 411 is in contact with the top of the mold 3. At the same time, the movement of the outer shell 43 drives the arc plate 411 to move. When the arc plate 411 moves, it can scrape off excess plastic particles from the surface of the mold 3, thereby avoiding waste of plastic particles and enabling excess plastic particles to be recycled and reused.

[0024] The stirring device 5 includes a second lead screw 51, a second transmission wheel 52, a first fixed plate 53, a limiting plate 54, a sliding plate 55, and a fixed rod 56. The second lead screw 51 is rotatably connected to the inner wall of the outer casing 43. The second transmission wheel 52 is fixedly connected to the circumferential surface of the second lead screw 51. The first fixed plate 53 is fixedly connected to the inner wall of the outer casing 43. The limiting plate 54 is fixedly connected to the surface of the first fixed plate 53. The sliding plate 55 is movably connected to the circumferential surface of the second lead screw 51. The fixed rod 56 is fixedly connected to the top of the sliding plate 55. The stirring device 5 also includes a third transmission wheel 57, a first stirring plate 58, a connecting rod 59, a fourth transmission wheel 510, a second stirring plate 511, and a protrusion 512. The third drive wheel 57 is rotatably connected to the circumferential surface of the fixed rod 56, and the first stirring plate 58 is fixedly connected to the top of the third drive wheel 57. During material spreading, the first drive wheel 45 rotates, driving the second drive wheel 52 to rotate. The second drive wheel 52 rotates, driving the second lead screw 51 to rotate. The second lead screw 51 rotates, driving the sliding plate 55 to move. The sliding plate 55 moves, driving the fixed rod 56 to move. The fixed rod 56 moves, driving the third drive wheel 57 to move. The third drive wheel 57 rotates through friction with the inner wall of the outer shell 43. The rotation of the third drive wheel 57 drives the first stirring plate 58 to rotate, thereby agitating the various plastic particles introduced into the outer shell 43, so that the various plastic particles can be mixed. The more uniform mixing improves the quality of the plastic pallets produced in subsequent processing. Connecting rod 59 is rotatably connected to the surface of fixed rod 56. Transmission wheel four 510 is rotatably connected to the end of connecting rod 59 away from fixed rod 56. Agitator plate two 511 is fixedly connected to the surface of transmission wheel four 510. Protrusion 512 is fixedly connected to the inner wall of outer shell 43. The circumferential surface of transmission wheel two 52 is in contact with the circumferential surface of transmission wheel one 45. The inner wall of outer shell 43 is in contact with the circumferential surface of transmission wheel three 57. The inner wall of limiting plate 54 is in contact with the surface of sliding plate 55. The circumferential surface of transmission wheel four 510 is in contact with the inner wall of outer shell 43. Simultaneously, the movement of the fixed rod 56 drives the connecting rod 59 to move, which in turn drives the transmission wheel 510 to move. The transmission wheel 510 rotates due to friction with the inner wall of the outer casing 43. The rotation of the transmission wheel 510 drives the stirring plate 511 to rotate, thereby increasing the stirring effect on the plastic particles and making the plastic particles more evenly stirred. When the transmission wheel 510 moves, it will contact the protrusion 512, causing the transmission wheel 510 to knock and vibrate the outer casing 43, thereby shaking off the plastic particles attached to the inner wall of the outer casing 43, improving the utilization rate of the plastic particles, and keeping the inside of the device clean when it is no longer in use.

[0025] Working principle: When the material feeding begins, the plastic mold 3 and conveyor 2 move to the designated feeding position. Then, the worker adds various plastic granules into the outer shell 43. At this time, the motor 47 starts, which drives the lead screw 41 to rotate. The rotation of the lead screw 41 drives the sliding block 42 to move, which in turn moves the outer shell 43. The movement of the outer shell 43 drives the rotating shaft 44 to move, which in turn moves the transmission wheel 45. After moving a certain distance, the transmission wheel 45 contacts the top of the mold 3, allowing the transmission wheel 45 to pass through the mold. The friction between the mold 3 causes the transmission wheel 45 to rotate, which in turn drives the rotating shaft 44 to rotate. The rotating shaft 44 then drives the limiting roller 46 to rotate, thereby limiting the outflow of plastic granules and preventing them from flowing out too quickly. This ensures that the material is discharged more evenly and prevents the plastic granules in the mold 3 from being unevenly distributed. At the same time, the movement of the outer shell 43 causes the arc plate 411 to move. When the arc plate 411 moves, it can scrape off excess plastic granules from the surface of the mold 3, thereby preventing the waste of plastic granules and allowing excess plastic granules to be recycled and reused.

[0026] During material spreading, the rotation of drive wheel 45 drives drive wheel 52 to rotate, which in turn drives screw 51 to rotate. Screw 51 moves sliding plate 55, which in turn moves fixed rod 56. Fixed rod 56 then moves drive wheel 57. Drive wheel 57 rotates due to friction with the inner wall of outer shell 43, which in turn drives agitator 58 to rotate. This agitation stirs the various plastic granules introduced into outer shell 43, resulting in a more uniform mixture. This improves the quality of the plastic pallets produced in subsequent processing. The movement of the fixed rod 56 drives the connecting rod 59 to move, which in turn drives the transmission wheel 510 to move. The transmission wheel 510 rotates due to friction with the inner wall of the outer casing 43. The rotation of the transmission wheel 510 drives the stirring plate 511 to rotate, thereby increasing the stirring effect on the plastic particles and making the plastic particles more evenly agitated. When the transmission wheel 510 moves, it will contact the protrusion 512, causing the transmission wheel 510 to knock and vibrate against the outer casing 43, thereby shaking off the plastic particles attached to the inner wall of the outer casing 43, improving the utilization rate of the plastic particles, and keeping the inside of the device clean when it is no longer in use.

[0027] Please see Figures 1-9Based on the above embodiments, in another embodiment of the present invention, the clamping device 6 includes a fixed block 61, a clamping plate 62, a transmission spring 63, an inclined block 64, a collection box 65, a push block 66, an L-shaped plate 67, and a push plate 68. The fixed block 61 is fixedly connected to the inner wall of the support leg 1, the clamping plate 62 is slidably connected to the inner wall of the fixed block 61, the transmission spring 63 is installed between the clamping plate 62 and the fixed block 61, and the inclined block 64 is fixedly connected to the front of the arc plate 411. During material laying, the arc plate 411 moves, driving the inclined block 64 to move. When the inclined block 64 moves a certain distance, it no longer limits the clamping plate 62. The clamping plate 62 moves under the elastic force of the transmission spring 63, thereby correcting and clamping the mold 3 on the conveyor table 2. This avoids inaccurate placement of the mold 3, which could lead to inaccurate subsequent plastic granule laying and waste of plastic granules, affecting the material laying process. The device works as follows: the collection box 65 is installed on the right side of the support leg 1; the push block 66 is fixedly connected to the inner wall of the arc plate 411; the push plate 68 is rotatably connected to the inner wall of the collection box 65 via a torsion spring; the L-shaped plate 67 is fixedly connected to the rear of the push plate 68; the left side of the inclined block 64 is in contact with the right side of the clamping plate 62; the rear of the push block 66 is in contact with the front of the L-shaped plate 67; and the top of the inner wall of the collection box 65 is in contact with the bottom of the push plate 68. Simultaneously, the arc plate 411 sweeps excess plastic particles into the collection box 65. The movement of the arc plate 411 moves the push block 66, which in turn moves the L-shaped plate 67, which in turn moves the push plate 68. This agitates the collected plastic particles, preventing them from accumulating on the right side of the collection box 65, increasing the capacity of the collection box 65, and preventing excessive accumulation and overflow of plastic particles.

[0028] Working principle: During material spreading, the arc plate 411 moves, driving the inclined block 64 to move. When the inclined block 64 moves a certain distance, it no longer limits the clamping plate 62. The clamping plate 62 moves under the elastic force of the transmission spring 63, thereby correcting and clamping the mold 3 on the conveyor table 2. This prevents inaccurate placement of the mold 3, which would lead to inaccurate spreading of subsequent plastic granules, resulting in waste of plastic granules and affecting the effectiveness of the device. At the same time, the arc plate 411 sweeps excess plastic granules into the collection box 65. The movement of the arc plate 411 drives the pusher block 66 to move, which in turn pushes the L-shaped plate 67 to move. The movement of the L-shaped plate 67 drives the pusher plate 68 to move, which can agitate the collected plastic granules. This prevents the collected plastic granules from accumulating on the right side of the collection box 65, increases the capacity of the collection box 65, and prevents excessive accumulation of plastic granules from overflowing.

[0029] This invention provides a uniform material spreading device for a sheet machine in plastic pallet production. Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of the invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technology.
