Description

Technical Field

[0001] The utility model relates to the technical field of finished product packaging and packing, in particular to a packaging device with a low-cost replacement pressure head. Background Art

[0002] During the production of viscose staple fibers, the finished products need to be packed in bags at the final stage, which is to facilitate the storage of the products and the transportation of the finished products. When packing, the finished products need to be pressed by the cylinder to press the head, press the fibers between the bottom plate and the pressing plate, then tighten the bag to wrap the fibers, and evenly tie the strapping tape to the bag through the holes on the pressing head and the pressing plate to pack the finished products.

[0003] As the variety of products increases, different products have different packaging requirements. Some require 5 strapping belts, and some require 4 strapping belts. However, the existing packaging device can only achieve even distribution of 5 strapping belts, but cannot achieve even distribution of 4 strapping belts, which cannot meet the production needs of different products. At the same time, in order to save costs, most products use 4 strapping belts when the packaging requirements are met, but the existing packaging device cannot achieve this.

[0004] In view of the above problems, the utility model designs and manufactures a packaging device with a low-cost replacement pressure head to overcome the above defects. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a packaging device with a low-cost replacement pressure head, which can meet the packaging needs of different numbers of packaging belts.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: a packaging device with low-cost replacement of a pressure head, comprising a lower pressure head and an upper pressure head arranged above the lower pressure head, a driving device for driving the upper pressure head to rise and fall is arranged on the top of the upper pressure head, and the upper pressure head can be detachably mounted on the driving device;

[0007] The upper pressure head comprises an upper wear belt five-hole main pressure head and an upper wear belt four-hole main pressure head, the lower end surface of the bottom of the upper wear belt five-hole main pressure head is evenly distributed with five upper wear belt holes, the lower end surface of the bottom of the upper wear belt four-hole main pressure head is evenly distributed with four upper wear belt holes, the spacing between the two outermost upper wear belt holes at the bottom of the upper wear belt five-hole main pressure head is equal to the spacing between the two outermost upper wear belt holes at the bottom of the upper wear belt four-hole main pressure head, and the upper wear belt five-hole main pressure head or the upper wear belt four-hole main pressure head can be detachably mounted on the driving device respectively;

[0008] The pressing head includes a lower bottom plate. On the left and right sides above the lower bottom plate, there are two fixed lower modules. An active lower module is detachably installed between the two fixed lower modules, and there are gaps between the active lower module and the two fixed lower modules; on the upper end faces of the two fixed lower modules, there are lower belt-passing holes. The lower belt-passing holes on the two fixed lower modules can respectively correspond to the two outermost upper belt-passing holes at the bottom of the five-hole main upper belt-pressing head or the two outermost upper belt-passing holes at the bottom of the four-hole main upper belt-pressing head.

[0009] The active lower module includes a single-hole belt-passing lower module and a double-hole belt-passing lower module. On the upper end face of the single-hole belt-passing lower module, there is one lower belt-passing hole. The lower belt-passing hole on the single-hole belt-passing lower module can correspond to the upper belt-passing hole at the middle position at the bottom of the five-hole main upper belt-pressing head. The gaps between the two sides of the single-hole belt-passing lower module and the two fixed lower modules respectively correspond to the remaining two upper belt-passing holes at the bottom of the five-hole main upper belt-pressing head. On the upper end face of the double-hole belt-passing lower module, there are two lower belt-passing holes. The two lower belt-passing holes on the double-hole belt-passing lower module can correspond to the two upper belt-passing holes at the middle position at the bottom of the four-hole main upper belt-pressing head.

[0010] Preferably, the driving device is a hydraulic cylinder.

[0011] Preferably, the two fixed lower modules are both detachably installed on the lower bottom plate.

[0012] Preferably, the upper belt-passing hole is an upper through groove penetrating the upper pressing head in the front-back direction, and the lower belt-passing hole is a lower through groove penetrating the active lower module in the front-back direction.

[0013] Preferably, the width of the notch of the upper through groove is smaller than the width inside the upper through groove, and the width of the notch of the lower through groove is smaller than the width inside the lower through groove.

[0014] Preferably, the single-hole belt-passing lower module and the double-hole belt-passing lower module have the same external dimensions.

[0015] Preferably, the gap between the active lower module and the two fixed lower modules is not less than the width of the forklift fork.

[0016] Preferably, the upper pressing head is a pressing plate. The upper belt-passing hole is arranged on the lower end face of the upper pressing plate. Above the pressing plate, there is a pressing seat, and the pressing seat is connected to the driving end of the driving device.

[0017] The advantages of this utility model are as follows:

[0018] 1. When five packing belts are needed for the present utility model, the upper belt-passing five-hole main pressure head and the belt-passing single-hole lower module are selected for combination. When four packing belts are needed, the upper belt-passing four-hole main pressure head and the belt-passing double-hole lower module are selected for combination. When facing the switching of the number of packing belts, only the corresponding upper pressure head and the movable lower module need to be replaced, and the two fixed lower modules do not need to be replaced. On the one hand, the cost of machining an entire lower pressure head can be saved. On the other hand, since the overall weight of the movable lower module is much smaller than that of a lower pressure head, the actual replacement efficiency is also improved.

[0019] 2. The forklift fork directly uses the gap between the movable lower module and the two fixed lower modules to transfer the packaged packaging bag on the lower pressure head, which is simple and efficient. Moreover, when the present utility model has five packing belts, that is, when the belt-passing single-hole lower module is selected, the two gaps can also function as lower belt-passing holes, facilitating two packing belts to pass through the two gaps, eliminating the need for machining the lower belt-passing holes.

[0020] 3. The outer dimensions of the belt-passing single-hole lower module and the belt-passing double-hole lower module of the present utility model are the same, so that the distance between the two gaps is the same whether there are five packing belts or four packing belts, eliminating the need to change the distance between the forklift forks.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] For the convenience of those skilled in the art to understand, the present utility model will be further described below with reference to the accompanying drawings.

[0026] As Figures 1 to 3 shown, a packing device with a low-cost replaceable pressure head includes a lower pressure head and an upper pressure head arranged above the lower pressure head. A driving device 1 for driving the upper pressure head to lift is provided at the top of the upper pressure head. The upper pressure head is detachably installed on the driving device 1, and the driving device 1 is preferably set as a hydraulic cylinder;

[0027] Specifically, the upper pressure head includes an upper through-belt five-hole main pressure head 3 and an upper through-belt four-hole main pressure head 12. The lower end surface of the bottom of the upper through-belt five-hole main pressure head 3 is evenly and evenly distributed with five upper through-belt holes 4. The lower end surface of the bottom of the upper through-belt four-hole main pressure head 12 is evenly and evenly distributed with four upper through-belt holes 4. Specifically, the upper through-belt holes 4 are set as upper through-belt grooves that penetrate the front and rear directions of the upper pressure head. The spacing between the two outermost upper through-belt holes 4 at the bottom of the upper through-belt five-hole main pressure head 3 is equal to the spacing between the two outermost upper through-belt holes 4 at the bottom of the upper through-belt four-hole main pressure head 12. The upper through-belt five-hole main pressure head 3 or the upper through-belt four-hole main pressure head 12 can be detachably installed on the driving device 1 respectively;

[0028] The lower pressure head includes a lower bottom plate 9, and two fixed lower modules 5 are arranged on the left and right sides above the lower bottom plate 9. The two fixed lower modules 5 can be detachably installed on the lower bottom plate 9, and a movable lower module can be detachably installed between the two fixed lower modules 5. A gap 6 is arranged between the movable lower module and the two fixed lower modules 5; the upper end surfaces of the two fixed lower modules 5 are provided with lower belt holes 7, and the lower belt holes 7 on the two fixed lower modules 5 can respectively correspond to the two outermost upper belt holes 4 at the bottom of the upper belt five-hole main pressure head 3 or the two outermost upper belt holes 4 at the bottom of the upper belt four-hole main pressure head 12;

[0029] The movable lower module of the utility model comprises a single-hole belt-threading lower module 8 and a double-hole belt-threading lower module 11. A lower belt-threading hole 7 is provided on the upper end surface of the single-hole belt-threading lower module 8. The lower belt-threading hole 7 on the single-hole belt-threading lower module 8 can correspond to the upper belt-threading hole 4 at the middle position of the bottom of the upper belt-threading five-hole main pressure head 3. The gaps 6 between the two sides of the single-hole belt-threading lower module 8 and the two fixed lower modules 5 respectively correspond to the remaining two upper belt-threading holes 4 at the bottom of the upper belt-threading five-hole main pressure head 3. Two lower belt-threading holes 7 are provided on the upper end surface of the double-hole belt-threading lower module 11. The two lower belt-threading holes 7 on the double-hole belt-threading lower module 11 can correspond to the two upper belt-threading holes 4 at the middle position of the bottom of the upper belt-threading four-hole main pressure head 12. Specifically, the lower belt-threading hole 7 is set as a lower through groove running through the front and rear directions of the movable lower module.

[0030] Moreover, the notch width of the upper through-groove is smaller than the width inside the upper through-groove, and the notch width of the lower through-groove is smaller than the width inside the lower through-groove, thereby preventing the strapping tape 10 from detaching from the upper through-groove and the lower through-groove as much as possible.

[0031] The outer dimensions of the single-hole lower module 8 and the double-hole lower module 11 are the same, so that the spacing between the two gaps 6 is consistent when facing five strapping straps 10 and four strapping straps 10, thus eliminating the need to change the spacing between forklift forks.

[0032] Of course, the gap 6 between the movable lower module and the two fixed lower modules 5 must be no less than the width of the forklift fork to ensure that the fork can be inserted into the gap 6.

[0033] The upper pressure head is preferably set as a pressing plate, specifically made of an iron plate with a thickness of 100 mm. The upper through-hole belt 4 is arranged on the lower end face of the upper pressing plate. A pressure seat 2 is arranged above the pressing plate, and the pressure seat 2 is connected to the driving end of the driving device 1.

[0034] During specific operation, the viscose fiber falls into the cotton box. After reaching a certain weight, the hydraulic cylinder drives the upper pressure head to press the viscose fiber. After the cotton box is lifted, the outer packaging bag of the fiber is lifted and installed. When five packing belts 10 are needed, the packing belts 10 are passed through the upper through-hole 4 on the upper through-hole five-hole main pressure head 3, the lower through-hole 7 on the through-hole single-hole lower module 8, and the gaps 6 between the two sides of the through-hole single-hole lower module 8 and the two fixed lower modules 5, so as to realize the bundling of 5 packing belts 10. At the same time, this gap 6 is used as the forklift fork when unloading the package.

[0035] When there is a production replacement requirement and four packing belts 10 are used for bundling, the upper pressure head needs to be removed, and the upper through-hole five-hole main pressure head 3 is replaced with the upper through-hole four-hole main pressure head 12. The two fixed lower modules 5 remain unchanged, and only the through-hole single-hole lower module 8 needs to be replaced with the through-hole double-hole lower module 11. The gap 6 between the two fixed lower modules 5 and the through-hole single-hole lower module 8 is still used as the forklift fork, so as to realize rapid and low-cost replacement between different bundling requirements.

[0036] It should be understood that the use of these embodiments is only for explaining the present invention and is not intended to limit the protection scope of the present invention. In addition, it should also be understood that after reading the technical content of the present invention, those skilled in the art can make various changes, modifications and / or variations to the present invention, and all these equivalent forms also fall within the protection scope defined by the appended claims of this application.
