Description

Technical Field

[0001] The invention relates to the technical field of punching holes in loose materials, and in particular to a punching and punching device for loose materials. Background Art

[0002] At present, loose materials such as edible mushroom bags often need to be punched during processing to facilitate subsequent packaging, storage or cultivation operations. However, the physical properties of loose materials, such as easy rolling and uneven distribution, bring considerable challenges to the punching operation. Traditional loose material punching machines usually adopt a two-step operation method: first, use a pressing plate or similar device to press and level the material to ensure that the material remains stable during the punching process and does not move or roll with the punching action; then, the punching rod is used to punch the leveled material.

[0003] Although this two-step operation method meets the basic needs of punching loose materials to a certain extent and has been widely used for its simple operation process, its limitations are becoming increasingly prominent. On the one hand, loose materials will become compacted and hardened after being subjected to pressure. This physical change makes it difficult for the punching rod to reach the predetermined punching depth within the limited punching space and time, which may result in insufficient punching depth and fail to meet the customer's strict requirements for the hole depth. On the other hand, as the punching rod gradually increases the resistance it encounters when penetrating into the compacted loose material, the material structure around the loose material channel is easily damaged, causing the hole shape after punching to collapse and become uneven.

[0004] Therefore, in view of the problems existing in traditional loose material punching machines, it is necessary to develop a new type of punching device to overcome the challenges brought by the physical properties of loose materials and meet customers' needs for high-quality punching operations.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The invention provides a punching and perforating device for loose materials, which is used to solve the problem of how to improve the punching quality.

[0034] See also Figure 1 and Figure 2 As shown, Figure 1 It is a three-dimensional diagram of the punching and perforating device for loose materials in the embodiment, Figure 2 Schematic diagram of the structure of a pressing barrel, a punch rod and a punch rod driving mechanism in an embodiment. The punching and punching device for loose materials includes a frame 1, a pressing barrel 2, a pressing barrel driving mechanism 3, a punch rod 4 and a punch rod driving mechanism 5.

[0035] The pressing barrel driving mechanism 3 is mounted on the frame 1 and is in driving connection with the pressing barrel 2. The pressing barrel driving mechanism 3 is used to drive the pressing barrel 2 to move up and down to loosen or press down the loose materials.

[0036] The punch rod driving mechanism 5 is fixedly installed in the pressing barrel 2, and the punch rod 4 penetrates the pressing barrel 2. The punch rod driving mechanism 5 is transmission-connected with the punch rod 4, and the punch rod driving mechanism 5 is used to drive the punch rod 4 to move up and down to punch holes in the loose material.

[0037] When the punching and punching device for loose materials of the above technical solution is used, first, the barrel driving mechanism 3 drives the barrel 2 to descend and contact the loose materials to limit the loose materials to remain stable and ensure the accuracy of the punching position. Then the punch rod driving mechanism 5 drives the punch rod 4 to descend, thereby initially forming a material hole on the loose material with the same cross-sectional shape and diameter as the punch rod 4, which plays a role in shaping the material hole. Then, the barrel driving mechanism 3 drives the barrel 2 to continue to descend and compact the loose materials, so that the loose materials are gradually compacted, thereby making the hole shape of the material hole more compact, and at the same time, the punch rod 4 descends together with the barrel 2, so that the material hole reaches a predetermined punching depth. After the punching is completed, the punch rod driving mechanism 5 drives the punch rod 4 to rise, and then the barrel driving mechanism 3 drives the barrel 2 to rise, so as to prevent the material hole channel from being damaged and causing the material hole to collapse and be uneven. It can be seen that the punching and punching device for loose materials can punch holes in any loose materials through the cooperation of the pressing barrel 2, the pressing barrel driving mechanism 3, the punch rod 4 and the punch rod driving mechanism 5. It has a wide range of applications, and the punching hole method can make the hole shape more compact and smooth, and can reach a predetermined punching depth, thereby effectively improving the punching quality and meeting customers' strict requirements on hole depth and hole shape.

[0038] The bottom of the punch rod 4 may be conical, which makes it easier for the punch rod 4 to punch holes in loose materials. The punch rod drive mechanism 5 may use a linear displacement drive mechanism such as an existing telescopic cylinder or a telescopic electric pole, and may be fixedly installed in the press barrel 2 by screwing or welding, and the output end of the punch rod drive mechanism 5 may be connected to the punch rod 4 by screwing or welding.

[0039] See also Figure 1 As shown, in one embodiment of the barrel driving mechanism 3, the barrel driving mechanism 3 includes a rotary drive member 31 and a linear drive assembly 32. The output end of the rotary drive member 31 is connected to the barrel 2 for driving the barrel 2 to rotate. The linear drive assembly 32 is mounted on the frame 1, and the output end of the linear drive assembly 32 is connected to the rotary drive member 31, and the linear drive assembly 32 is used to drive the rotary drive member 31 to move up and down. In this way. The barrel driving mechanism 3 can drive the barrel 2 to descend through the linear drive assembly 32 to punch the loose material, and after the punching is completed, the barrel driving mechanism 3 can drive the barrel 2 to spirally rise through the rotary drive member 31 and the linear drive assembly 32, so that the formed material surface can be flat and less sticky, and the tightness of the mushroom bag can be moderately adjustable; and the barrel driving mechanism 3 can also cooperate with the punch rod driving mechanism 5 to realize spiral drilling, and the material hole can be formed in various ways.

[0040] The above-mentioned rotating driving member 31 can use an existing rotating driving mechanism such as a rotating motor or a rotating cylinder. The output end of the rotating driving member 31 can be connected to the pressing barrel 2 in a detachable manner such as screw connection or clamping, which is convenient for maintenance or replacement of the pressing barrel 2, the punch rod 4 and the punch rod driving mechanism 5. In this way, the punch rod 4 with different outer diameters can be replaced as needed.

[0041] See also Figure 1 and Figure 2 As shown, on the basis of the above embodiment, the number of the punch rods 4 is at least two. The number of the punch rods 4, the punch rod driving mechanism 5, the press cylinder 2 and the rotary drive member 31 is the same and corresponds to each other. The output end of the linear drive assembly 32 is connected to at least two rotary drive members 31. In this way, the punching and perforating device can punch multiple holes at one time, greatly improving the production efficiency, and the linear drive assembly 32 can lift multiple rotary drive members 31 at one time, greatly reducing the driving cost.

[0042] See also Figure 1As shown, in one embodiment of the linear displacement drive assembly, the linear displacement drive assembly includes a motor 321, a screw rod 322 and a slide 323, and a slide rail 11 is provided on the frame 1 by screwing or welding. The motor 321 is provided on the frame 1 by screwing or welding, the screw rod 322 is rotatably connected to the frame 1 through a bearing, and the output end of the motor 321 is connected to the screw rod 322 by screwing or welding. The slide 323 is threadedly connected to the screw rod 322 and slides with the slide rail 11. A plurality of rotary drive members 31 are fixed to the same slide 323 by screwing or welding. In this way, the motor 321 drives the screw rod 322 to rotate, which can drive the slide 323 to slide along the slide rail 11, thereby driving the plurality of rotary drive members 31 and the press barrel 2 to move up and down together, wherein the slide 323 and the slide rail 11 slide in cooperation, which can improve the stability of the lifting and lowering movement of the press barrel 2, thereby improving the stability of the stamping process.

[0043] In addition to the above-mentioned embodiments, the linear drive assembly 32 may also adopt existing linear displacement drive mechanisms such as linear motor modules, synchronous belt linear modules, etc.

[0044] See also Figure 2 As shown, on the basis of any of the above embodiments, a partition 21 is provided in the press barrel 2 by welding or clamping. The partition 21 divides the internal space of the press barrel 2 into a first accommodating chamber 22 and a second accommodating chamber 23. The first accommodating chamber 22 is used to accommodate the punch rod drive mechanism 5, and the second accommodating chamber 23 is used to accommodate the punch rod 4. In this way, the punch rod drive mechanism 5 is fixedly installed in the first accommodating chamber 22, and the output end of the punch rod drive mechanism 5 passes through the partition 21 and extends into the second accommodating chamber 23, and is connected to the punch rod 4. The punch rod 4 and the punch rod drive mechanism 5 are separated by the partition 21, which effectively prevents the material debris adhering to the punch rod 4 from entering the punch rod drive mechanism 5, thereby affecting the normal use of the punch rod drive mechanism 5, and plays a role in protecting the punch rod drive mechanism 5.

[0045] See also Figure 1 and Figure 2 As shown, on the basis of the above embodiment, a chip removal groove 24 is opened on the inner wall of the second accommodating chamber 23 and is connected to the outside of the pressing barrel 2. In this way, the chip removal groove 24 can facilitate the discharge of material debris adhered to the punch rod 4 from the second accommodating chamber 23, thereby preventing material debris from accumulating in the second accommodating chamber 23, thereby affecting the lifting action of the punch rod 4.

[0046] See also Figure 1 and Figure 2As shown, on the basis of the above embodiment, there are at least two chip grooves 24, at least two chip grooves 24 are equally spaced around the axial direction of the punch rod 4, and the length direction of the chip grooves 24 is parallel to the axial direction of the punch rod 4. In this way, the staff uses an air gun or other blowing equipment to blow air into the press barrel 2 through any chip groove 24, and can quickly and easily blow out most of the material debris on the punch rod 4 and in the press barrel 2 from other chip grooves 24, which has a better effect on the maintenance and chip removal of the punch rod 4 and the press barrel 2. In this embodiment, there are two chip grooves 24 on the press barrel 2, and the positions of the two chip grooves 24 are relatively distributed.

[0047] The chip removal groove 24 may be opposite to the punch rod 4, and the longer the chip removal groove 24 is, the better the chip removal effect is.

[0048] See also Figure 1 and Figure 2 As shown, the pressing cylinder 2 includes a pressing plate 25 for contacting the loose material, and the pressing plate 25 has a through hole 251 for the punch rod 4 to pass through. The pressing plate 25 and the punch rod 4 are both made of stainless steel. In this way, the punching and punching device for loose materials mainly contacts the loose materials through the pressing plate 25 and the punch rod 4, and the pressing plate 25 and the punch rod 4 are both made of stainless steel, which can effectively prevent the punching and punching device for loose materials from being corroded by the loose materials, thereby extending the service life and facilitating cleaning. Moreover, the punching and punching device for loose materials can only use stainless steel for the pressing plate 25 and the punch rod 4, and other parts can use other materials with lower prices, which can reduce the production cost of the punching and punching device for loose materials. Among them, the pressing plate 25 also has a scraping effect through the through hole 251, which can scrape off most of the materials attached to the punch rod 4.

[0049] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
