Description

Technical Field

[0001] The invention relates to the technical field of balers on a chemical staple fiber production line, in particular to a novel chemical fiber baler. Background Art

[0002] In the chemical staple fiber production line, since the incoming material is continuous and the baler outputs the bales intermittently, the free stacking density of the fiber is relatively small. Each bale of fiber needs to be metered, pushed, and pre-pressed into the compression box several times. The baler must separate the pre-pressing and main pressing stations. In the scheme of transferring the fiber from the pre-pressing station to the main pressing station, the mainstream form is the double-box and transfer box type. However, in large-capacity balers, there are ways to transfer only the fiber with or without compression boxes and fork transport devices.

[0003] Among the box-free transfer balers, the fully automatic balers currently available on the market have two types: the strapping is first tied inside and then covered with film, and the upper and lower wrapping cloths are laid on the main pressing side. In the former, the fibers are in direct contact with the strapping tape, and the dust from the strapping tape welding and the surface of the strapping tape will cause certain pollution to the fibers. In the latter, the wrapping cloth on the main pressing side is laid between the upper and lower pressing plates and the fiber transfer fork. The wrapping cloth is easily crushed by the pressing head and fork, and the additional requirements for the strength of the wrapping cloth are greater than the packaging and transportation requirements, resulting in increased use costs.

[0004] In view of the above situation, and in order to adapt to large-capacity, fully automatic baling machines, we have invented a new type of chemical fiber baling machine. Summary of the invention

[0005] In view of the problems raised by the background technology, the purpose of the present invention is to propose a new type of chemical fiber baling machine to solve the problems.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A novel chemical fiber baler includes a frame and:

[0008] A cloth wrapping system, arranged on one side of the frame;

[0009] A compression box is installed inside the frame, and a sealing frame is provided at the upper end of the compression box;

[0010] A lower pre-pressing member, arranged at the bottom side of the compression box, and connected to the frame;

[0011] An upper pre-pressing member is arranged on the upper side of the compression box, and the upper pre-pressing member is connected to the frame.

[0012] As a further technical solution of the present invention, the lower pre-press comprises:

[0013] A lower preloading cylinder, one end of which is connected to the frame;

[0014] The lower pre-compression head is arranged at one end of the lower pre-compression cylinder close to the compression box.

[0015] As a further technical solution of the present invention, the upper pre-press comprises:

[0016] An upper preloading cylinder, one end of which is connected to the frame;

[0017] An upper pre-compression head is installed on one end of the upper pre-compression cylinder close to the compression box.

[0018] As a further technical solution of the present invention, the cloth wrapping system is provided with a lower cloth wrapping on the upper end of the lower pre-pressing head, and the cloth wrapping system is provided with an upper cloth wrapping in the gap between the sealing frame and the compression box.

[0019] As a further technical solution of the present invention, it also includes a bullet-proof hook, and the bullet-proof hook is arranged on the upper side of the compression box.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention provides a fully automatic chemical fiber baling machine suitable for large capacity and multiple stations. The chemical fiber baling machine can realize the laying of upper and lower wrapping cloths on the pre-pressing side, avoiding the wrapping cloths from being subjected to additional pressure. The present invention also avoids the fibers from being contaminated during the baling process. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 It is a structural schematic diagram of a new type of chemical fiber baling machine.

[0022] In the figure: 1-lower pre-pressing cylinder, 2-lower pressure head, 3-lower cloth wrapping, 4-frame, 5-compression box, 6-bulletproof hook, 7-upper cloth wrapping, 8-sealing frame, 9-upper pre-pressing head, 10-upper pre-pressing cylinder, 11-cloth wrapping system. DETAILED DESCRIPTION

[0023] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0024] The embodiment of the present invention is implemented as follows: Figure 1 A novel chemical fiber baler shown includes a frame 4 and also includes:

[0025] A cloth wrapping system 11 is arranged on one side of the frame 4;

[0026] A compression box 5 is installed inside the frame 4, and a sealing frame 8 is provided at the upper end of the compression box 5;

[0027] A lower pre-pressing member, arranged at the bottom of the compression box 5, and connected to the frame 4;

[0028] An upper pre-pressing member is arranged on the upper side of the compression box 5 , and the upper pre-pressing member is connected to the frame 4 .

[0029] In this embodiment, a bulletproof hook 6 is further included. The bulletproof hook 6 is provided on the upper side of the compression box 5 to prevent the limiter in the compression box 5 from popping out.

[0030] When in use, the lower pre-pressing member stops at the lower cloth-laying position, and the cloth-laying system 11 lays down the cloth 3, which is fixed to the upper end of the lower pre-pressing member. Then the lower pre-pressing member rises to the lower opening of the compression box 5, waiting for feeding. After equal batches of metering, pushing, and pre-pressing, the sealing frame 8 rises after the fibers in the compression box 5 reach the set bag weight value. An empty channel is formed between the top surface of the compression box 5 and the bottom of the sealing frame 8, and the cloth-laying system 11 lays the upper cloth 7. Then the upper pre-pressing member descends and seals the upper opening of the compression box 5, the bulletproof hook 6 opens, and the pre-pressing continues to descend to reach the bagging height, and then the upper and lower pre-pressing members descend synchronously, and the fibers escape from the fixed compression box 5. At this point, the pre-compressed fibers and the upper and lower cloths are compressed between the upper and lower pressure heads and reach the lower forklift operation position. Then the forklift enters the pre-pressing position, at which time the forks are outside the cloth, and then the upper and lower pre-pressing members retreat, and the fibers rebound and support themselves in the transfer fork and are transported to the main pressing position. The lower pre-pressing part is lowered to the cloth laying position, the cloth laying system 11 lays down the cloth, and the pre-pressing enters the next cycle.

[0031] In this embodiment, the lower pre-press comprises:

[0032] A lower pre-compression cylinder 1, one end of which is connected to the frame 4;

[0033] The lower pre-compression head 2 is arranged at one end of the lower pre-compression cylinder 1 close to the compression box 5 .

[0034] In this embodiment, the upper pre-press comprises:

[0035] An upper pre-compression cylinder 10, one end of which is connected to the frame 4;

[0036] The upper pre-compression head 9 is installed on one end of the upper pre-compression cylinder 10 close to the compression box 5 .

[0037] Working principle: When the machine is turned on, the lower pre-pressing cylinder 1 controls the lower pre-pressing head 2 to stop at the lower cloth-laying position, and the cloth-laying system 11 lays down the cloth-laying 3, which is fixed on the lower pre-pressing head 2. Then the lower pre-pressing cylinder 1 drives the lower pre-pressing head 2 to rise to the lower opening of the compression box 5, waiting for feeding. After equal batches of metering, pushing and pre-pressing, the sealing frame 8 rises after the fibers in the compression box 5 reach the set bag weight value. At this time, the fibers in the compression box 5 are controlled below by the bulletproof hook 6, and an empty channel is formed between the top surface of the compression box 5 and the bottom of the sealing frame 8. At this time, the cloth-laying system 11 lays the upper cloth-laying 7. Then the upper pre-pressing cylinder 10 controls the upper pre-pressing head 9 to descend and seal the upper opening of the compression box 5. The bulletproof hook 6 opens, and the pre-pressing continues to descend to reach the bag height. Then the upper and lower pre-pressing cylinders descend synchronously, and the fibers escape from the fixed compression box 5. At this point, the pre-compressed fibers and the cloth-layings above and below are compressed between the upper and lower pressure heads and reach the lower forklift operation position. Then the forklift enters the pre-pressing position, at which time the fork is outside the cloth, and then the upper and lower pre-pressing cylinders retreat, the fiber rebounds and is supported in the transfer fork, and is transported to the main pressing position. The lower pre-pressing head 2 is lowered to the cloth laying position, the cloth laying system 11 lays down the cloth, and the pre-pressing enters the next cycle.
