Description

Technical Field

[0001] This utility model belongs to the field of pallet production technology, specifically a multi-functional plastic pallet trimming machine. Background Technology

[0002] Plastic pallets are logistics units used in conjunction with logistics equipment such as forklifts and racks. They can be used to store, load, and move goods and are one of the essential logistics equipment in modern logistics warehousing. After the plastic pallets are produced through processes such as injection molding, there are usually burrs or other defects, so they need to be processed using a trimming machine.

[0003] Utility model patent application number 202323176490.4 discloses a multi-functional plastic pallet trimming machine. This machine uses two symmetrically arranged clamps to calibrate and position the plastic pallet conveyed on the conveyor belt, ensuring it moves with the belt between two symmetrical cutters and grinding plates for trimming during transport. However, friction exists between the clamps and the pallet during positioning, affecting the conveyor belt's operation and potentially preventing transmission. More importantly, the cutters and grinding plates are independently set up. After the clamps calibrate the pallet, the distance between the two symmetrical cutters and grinding plates must be manually calibrated to ensure they fit the pallet surface, increasing workload and reducing processing efficiency. Therefore, a new trimming machine for plastic pallet production needs to be developed to address these shortcomings. Utility Model Content

[0004] To address the problems mentioned in the background section, this utility model provides a multi-functional plastic pallet trimming machine, which has the advantages of stable transmission and high efficiency.

[0007] Preferably, the trimming linkage assembly includes a trimming linkage plate movably installed inside the conveying trough. The trimming linkage plate has an installation cavity at one end near the centerline of the conveying trough, and an installation groove in the middle of the side of the trimming linkage plate near the centerline of the conveying trough. Several positioning components are installed inside the installation cavity. The chip guide plate and several cutting blade components are all installed inside the installation groove. Positioning pins are movably sleeved in the middle of both the cutting blade components and the grinding components. The back sides of the cutting blade components and the grinding components are inserted into the trimming linkage plate. The cutting blade components and the grinding components are fixedly connected to the trimming linkage plate via the positioning pins.

[0008] Preferably, the positioning component includes a positioning roller movably installed inside the mounting cavity, a positioning shaft movably sleeved on the middle of the positioning roller, the upper and lower ends of the positioning shaft passing through the positioning roller and fixedly connected to the inner wall of the mounting cavity, and a plurality of evenly distributed fitting notches being opened on the outer surface of the positioning shaft; the height of the fitting notch is greater than the distance between two adjacent fitting notches.

[0009] Preferably, the cutter assembly is inclined, with the upper end of the cutter assembly close to the positioning assembly and the lower end of the cutter assembly away from the positioning assembly.

[0010] Preferably, the cutter assembly includes a cutter fixing part inserted into the trimming linkage plate. The front of the cutter fixing part extends into the mounting groove and is integrally formed with a cutter blade. A chip removal window is provided in the middle of the cutter blade. A positioning hole is provided in the middle of the cutter fixing part. The back of the inner cavity of the chip removal window is flush with the back of the inner cavity of the mounting groove.

[0011] Preferably, the polishing assembly includes a disassembly frame inserted into the trimming linkage plate. The front end of the disassembly frame extends to the front of the trimming linkage plate and is connected to a polishing disc. The polishing disc is fixedly connected to the disassembly frame via Velcro. The two ends of the front of the disassembly frame are curved surfaces, and the two ends of the polishing disc are tightly fitted with the curved surfaces at both ends of the disassembly frame.

[0012] Preferably, the positioning pin includes a pin body that is movably sleeved in the assembly / disassembly frame and inside the positioning hole. A fixing thread is formed on the back of the pin body, and the fixing thread is threaded into the interior of the trimming linkage plate. The front of the pin body is flush with the back of the chip removal window cavity and the front of the assembly / disassembly frame. The front of the assembly / disassembly frame is provided with an assembly / disassembly groove.

[0013] Preferably, a support frame is fixedly connected to the bottom of the conveyor frame, and a rotating rod is drivenly sleeved at both ends of the conveyor belt. The two ends of the rotating rod are movably sleeved inside the conveyor frame through bearings.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. Due to the setting of the trimming linkage component, the positioning component, cutting component and grinding component can move synchronously. This ensures that while the positioning components on both sides are calibrating the tray, the cutting component and grinding component are also calibrating, thereby improving operating efficiency.

[0017] 2. Due to the design of the cutter fixing part, the cutter assembly can be stably positioned on the trimming linkage assembly with the cooperation of the positioning hole and positioning pin, and it is also easy to disassemble and replace. Moreover, since the cutter assembly is inclined, when the cutter blade cuts, it will apply a downward pressure to the pallet, which will increase the friction between the pallet and the conveyor belt, ensuring that the pallet can move smoothly and continuously with the conveyor belt, and will not stop moving relative to the conveyor belt due to cutting resistance.

[0018] 3. Due to the chip removal window, this utility model, in conjunction with the chip guide plate, ensures that the burrs removed by the cutting edge can be removed in an orderly manner, avoiding them from remaining between the dressing component and the tray and affecting the subsequent grinding effect of the grinding disc.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 7 As shown, this utility model provides a multi-functional plastic pallet trimming machine, including a conveyor frame 1, a conveyor groove 2 opened on the top of the conveyor frame 1, a conveyor belt 3 installed inside the conveyor groove 2, two trimming components 4 located on the top of the conveyor belt 3 inside the conveyor groove 2, two front and rear transmission screws 6 arranged above the trimming components 4, and a drive component 5 connected to both ends of the transmission screws 6.

[0029] The trimming assembly 4 includes a trimming linkage assembly 41 fixedly connected to the bottom of the transmission screw 6 and movably attached to the top of the conveyor belt 3. Several evenly distributed positioning components 42 are movably embedded at one end of the opposing surfaces of the two trimming linkage assemblies 41. A grinding assembly 45 is fixedly installed at the other end of the opposing surfaces of the two trimming linkage assemblies 41. A chip guide plate 44 and several cutting assemblies 43 are fixedly installed in the middle of the opposing surfaces of the two trimming linkage assemblies 41. The positioning assembly 42, the grinding assembly 45, and one cutting assembly 43 away from the positioning assembly 42 are equidistant from the centerline of the conveyor trough 2. The remaining cutting assemblies 43 are equidistant from the centerline of the positioning assembly 42. Due to the arrangement of the trimming linkage assembly 41, the positioning assembly 42, the cutting assembly 43, and the grinding assembly 45 can move synchronously, ensuring that while the positioning assemblies 42 on both sides calibrate the pallet, the cutting assembly 43 and the grinding assembly 45 also complete calibration, thereby improving operating efficiency.

[0030] like Figure 4 As shown, the trimming linkage assembly 41 includes a trimming linkage plate 411 movably installed inside the conveying trough 2. One end of the trimming linkage plate 411 near the centerline of the conveying trough 2 has an installation cavity 412, and the middle part of the trimming linkage plate 411 near the centerline of the conveying trough 2 has an installation groove 413. Several positioning components 42 are installed inside the installation cavity 412. The chip guide plate 44 and several cutting blade components 43 are installed inside the installation groove 413. The middle parts of the cutting blade components 43 and the grinding components 45 are movably fitted with positioning pins 46. The back sides of the cutting blade components 43 and the grinding components 45 are inserted into the trimming linkage plate 411. The cutting blade components 43 and the grinding components 45 are fixedly connected to the trimming linkage plate 411 through the positioning pins 46.

[0031] like Figure 4 and Figure 5 As shown, the positioning assembly 42 includes a positioning roller 421 movably installed inside the mounting cavity 412. A positioning shaft 422 is movably sleeved in the middle of the positioning roller 421. The upper and lower ends of the positioning shaft 422 pass through the positioning roller 421 and are fixedly connected to the inner wall of the mounting cavity 412. The outer surface of the positioning shaft 422 is provided with a plurality of evenly distributed fitting notches 423. The height of the fitting notches 423 is greater than the distance between two adjacent fitting notches 423.

[0032] like Figure 4 and Figure 7As shown, the cutter assembly 43 is inclined, with the upper end of the cutter assembly 43 close to the positioning assembly 42 and the lower end of the cutter assembly 43 far away from the positioning assembly 42. Because the cutter assembly 43 is inclined, when the cutter blade 432 cuts, it will apply a downward pressure to the pallet, which will increase the friction between the pallet and the conveyor belt 3, ensuring that the pallet can move smoothly and continuously with the conveyor belt 3, and will not stop moving relative to the conveyor belt 3 due to cutting resistance.

[0033] like Figure 4 and Figure 7 As shown, the cutter assembly 43 includes a cutter fixing part 431 inserted into the dressing linkage plate 411. The front of the cutter fixing part 431 extends into the mounting groove 413 and is integrally formed with a cutter blade part 432. A chip removal window 433 is provided in the middle of the cutter blade part 432, and a positioning hole 434 is provided in the middle of the cutter fixing part 431. The back of the inner cavity of the chip removal window 433 is flush with the back of the inner cavity of the mounting groove 413. Due to the setting of the cutter fixing part 431, the cutter assembly 43 can be stably positioned on the dressing linkage assembly 41 with the cooperation of the positioning hole 434 and the positioning pin 46, and it is also easy to disassemble and replace. Due to the setting of the chip removal window 433, with the cooperation of the chip guide plate 44, it is ensured that the burrs cut by the cutter blade part 432 can be discharged in an orderly manner, avoiding them from remaining between the dressing assembly 4 and the tray and affecting the grinding effect of the subsequent grinding disc 452.

[0034] like Figure 4 As shown, the polishing assembly 45 includes a disassembly frame 451 inserted into the trimming linkage plate 411. The front end of the disassembly frame 451 extends to the front of the trimming linkage plate 411 and is connected to a polishing disc 452. The polishing disc 452 is fixedly connected to the disassembly frame 451 by Velcro. The two ends of the front of the disassembly frame 451 are curved surfaces, and the two ends of the polishing disc 452 are tightly fitted with the curved surfaces at both ends of the disassembly frame 451. Due to the setting of the disassembly frame 451, it is convenient to set the polishing disc 452 to ensure that the polishing disc 452 can polish the cut on the side of the tray, and it is also convenient to replace the polishing disc 452 to ensure the polishing effect.

[0035] like Figure 6 As shown, the positioning pin 46 includes a pin body 461 that is movably sleeved in the assembly / disassembly frame 451 and inside the positioning hole 434. A fixing thread 462 is formed on the back of the pin body 461. The fixing thread 462 is threaded into the inside of the trimming linkage plate 411. The front of the pin body 461 is flush with the back of the chip removal window 433 and the front of the assembly / disassembly frame 451. The front of the assembly / disassembly frame 451 is provided with an assembly / disassembly groove 463. Due to the setting of the pin body 461, the cutter assembly 43 and the grinding assembly 45 can be conveniently and quickly fixed with the cooperation of the fixing thread 462 and the trimming linkage plate 411.

[0036] like Figures 1 to 3 As shown, a support frame 7 is fixedly connected to the bottom of the conveyor frame 1, and a rotating rod 8 is driven to both ends of the conveyor belt 3. The two ends of the rotating rod 8 are movably sleeved inside the conveyor frame 1 through bearings.

[0037] The drive assembly 5 includes a positioning sleeve 51 fixedly connected to the top of the conveyor frame 1. Two linkage sleeves 52 are threaded between the two positioning sleeves 51 and connected to the outside of the transmission screw 6. The bottom of the linkage sleeve 52 is fixedly connected to the top of the trimming linkage plate 411. The two ends of the transmission screw 6 are movably connected to the inside of the positioning sleeves 51 through bearings. The two ends of the transmission screw 6 pass through the positioning sleeves 51 and are fixedly connected to the transmission pulleys 54. A drive motor 53 is fixedly installed on the support frame 7. A transmission pulley 54 is also fixedly connected to the rear end of the output shaft of the drive motor 53. A transmission belt 55 is connected between several transmission pulleys 54. Due to the setting of the two transmission screws 6, the transmission stability of the trimming assembly 4 can be improved with the cooperation of the linkage sleeves 52. It can also prevent the trimming assembly 4 from rotating with the transmission screw 6, thereby ensuring that when the transmission screw 6 rotates, it can drive the two trimming assemblies 4 to move closer or further away from each other synchronously.

[0038] Working principle and usage process of this utility model:

[0039] When the drive motor 53 is turned on, the two transmission screws 6 will rotate synchronously through the transmission belt 55 in cooperation with the transmission pulley 54 and the positioning sleeve 51. As the rotation of the two transmission screws 6 can drive the two trimming components 4 to move closer to each other in cooperation with the linkage sleeve 52, until the positioning components 42 in the two trimming components 4 are in contact with the left and right sides of the pallet. At the same time, the surface of the grinding component 45 and the blade of a cutting component 43 near the grinding component 45 are also located in the vertical plane on the left and right sides of the pallet. At this time, the pallet moves between the left and right trimming components 4 under the transmission of the conveyor belt 3.

[0040] Under the constraint of several positioning components 42 on the left and right sides, the pallet moves smoothly along a straight line. Since the distance between two adjacent matching notches 423 is small, the burrs protruding on the side of the pallet can be staggered to the greatest extent, so that the outer surface of the positioning component 42 can contact the actual side of the pallet without being affected by the burrs. At the same time, it ensures that the linked cutting component 43 and grinding component 45 can contact the side of the pallet.

[0041] When the pallet passes the cutter assembly 43, since the distance between the several cutter blades 432 and the side of the pallet is different, when the pallet passes through multiple cutter blades 432 in sequence, each cutter blade 432 can cut off the protrusions on the side of the pallet from shallow to deep. The cut protrusions are moved to the chip guide plate 44 through the chip removal window 433 and away from the pallet to avoid affecting the smooth movement of the pallet.

[0042] When the deburred tray moves to the grinding assembly 45, the grinding disc 452 can be pushed against the cut on the side of the tray for grinding under the support of the disassembly frame 451.

[0043] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
