Description

Technical Field

[0001] This utility model belongs to the technical field of leather processing equipment, and specifically relates to an improved leather dust removal machine. Background Technology

[0002] After processing, leather will have dust adhering to its surface. In order to ensure the quality of the leather and prevent dust from corroding the leather surface, it is usually necessary to use a dust removal machine to remove the dust from the leather. To improve work efficiency, specialized equipment is generally used for leather dust removal.

[0003] For example, Chinese utility model patent CN210945651U discloses a leather dust removal device, including a frame with a conveyor mechanism for transporting leather, the conveyor mechanism including a conveyor belt; the frame also has a first flattening mechanism and a second flattening mechanism for flattening the leather, the first flattening mechanism including a rotatable first pressing belt, and the second flattening mechanism including a rotatable second pressing belt, both the first and second pressing belts being in contact with the conveyor belt and located above the conveyor belt; a cover is provided between the first and second pressing belts, the cover being located above the conveyor belt, and the cover and the conveyor belt forming a gap for the leather to pass through, the cover containing a dust suction mechanism. Compared with the prior art, this utility model uses the first flattening mechanism to flatten the leather, which not only facilitates the leather to pass through the gap formed with the conveyor belt, but also facilitates the dust suction mechanism to remove dust from the leather, thereby achieving the purpose of dust removal.

[0004] As mentioned above, existing leather dust removal equipment typically uses a belt conveyor to transport the leather to a dust collection unit for surface dust removal (i.e., dust removal). However, the belt conveyor in existing leather dust removal equipment usually does not have a tension adjustment function. When the weight and size of the leather placed in the equipment vary greatly, it will affect the tension of the belt conveyor. Insufficient tension will cause the conveyor belt to slip, making it unable to transmit the required traction force. This is especially likely to cause slippage during startup or load changes, affecting the leather conveying efficiency. Excessive tension may increase the load on the rollers due to excessive friction between the conveyor belt and the rollers, accelerating the wear of the rollers and conveyor belt, and even causing equipment failure.

[0005] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to the occurrence of this case. Summary of the Invention

[0006] The purpose of this invention is to provide an improved leather dust removal machine that can adjust the tension of the belt conveyor mechanism so that the belt conveyor mechanism can stably transport leather of different weights.

[0007] To achieve the above objectives, this utility model adopts the following technical solution:

[0008] An improved leather dust removal machine includes a frame, on which a dust suction mechanism and a belt conveyor mechanism for conveying leather are mounted. The frame includes a connecting frame and fixed frames on both sides of the connecting frame, and support frames respectively mounted on the two fixed frames. The belt conveyor mechanism includes a drive roller, a driven roller, a support roller located between the drive roller and the driven roller, a conveyor belt wound around the drive roller, the driven roller, and the support roller, and a drive mechanism for driving the drive roller to rotate. The drive roller, the driven roller, and the support roller are all horizontally arranged. The two ends of the drive roller are rotatably mounted on the two fixed frames, and the two ends of the driven roller are rotatably mounted on the two support frames at the ends away from the fixed frames. Each of the two fixed frames has a swing block rotatably mounted on the side facing the support frame, and a swing control mechanism for controlling the swing block to swing up and down. The output end of the swing control mechanism is connected to the bottom of the swing block. The frame also has a first roller adjustment mechanism for adjusting the position of the support roller. The first roller adjustment mechanism is correspondingly mounted on both ends of the support roller and is mounted on the swing block.

[0009] Furthermore, the first roller adjustment mechanism includes a bearing seat and an adjusting bolt fixed on the swing block. The bearing seat has a through hole for the adjusting bolt to extend into. The two ends of the support roller are respectively rotatably disposed in the corresponding bearing seats.

[0010] Furthermore, the swing control mechanism is a telescopic cylinder, which is arranged vertically with its output end facing upward and hinged to the bottom of the swing block. The support frame is provided with a corresponding mounting groove for mounting the telescopic cylinder.

[0011] Furthermore, the swing block is provided with a first long groove corresponding to the position of the first roller adjusting mechanism, and the first roller adjusting mechanism is movably disposed on the first long groove.

[0012] Furthermore, the support frame is also provided with a second roller adjustment mechanism for adjusting the rotational speed of the driven roller, and the second roller adjustment mechanism has the same structure as the first roller adjustment mechanism.

[0013] Furthermore, guide rollers for guiding the conveyor belt are rotatably provided on one end of each of the two support frames near the driven roller. The two guide rollers are arranged facing each other, and the opposite ends of the two guide rollers are both inclined downwards.

[0014] Furthermore, the support frame is provided with a second long groove corresponding to the position of the second roller adjustment mechanism, and the second roller adjustment mechanism is movably mounted on the second long groove.

[0015] Furthermore, several pressing rollers for pressing the conveyor belt are rotatably mounted on the two support frames. The pressing rollers are arranged parallel to the drive roller and are located between the drive roller and the support roller.

[0016] Furthermore, the driving mechanism includes a drive motor fixed on the fixed frame and a chain wound around the output end of the drive motor and the drive roller. A sprocket is correspondingly provided on the output end of the drive motor, the pressure roller and the drive roller, and the pressure roller presses against the chain.

[0017] Furthermore, the support roller has a first guide section at both ends, the diameter of which gradually decreases from the inside to the outside, and the driven roller has a second guide section at both ends, the diameter of which gradually decreases from the inside to the outside.

[0018] By adopting the aforementioned design scheme, the beneficial effects of this utility model are:

[0019] This utility model discloses a leather dust removal machine with a simple structure. By setting up a swing block and controlling the swing of the support roller up and down through a swing control mechanism, the swing amplitude of the support roller can be controlled. When not in operation, controlling the support roller to swing downwards can also facilitate cleaning of the bottom of the dust collection mechanism. By setting up a first roller adjustment mechanism, the position of the support roller can be adjusted. Through the swing control mechanism and the first roller adjustment mechanism, the tension of the belt conveyor mechanism can be adjusted to adapt to leather of different weights, so that the belt conveyor mechanism can stably transport the leather to the dust collection mechanism. Compared with the prior art, it has the advantages of good operability and good conveying stability.

[0020] Furthermore, guide rollers are provided, and first guide sections are provided at both ends of the support rollers, and second guide sections are provided at both ends of the driven rollers, to prevent the conveyor belt from deviating to the outside of the support frame during movement, thereby further improving the stability of the conveying.

[0041] 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.

[0042] like Figures 1 to 3As shown, an improved leather dust removal machine includes a frame 1, on which a dust suction mechanism 10 and a belt conveyor mechanism 2 for conveying leather are mounted. The frame 1 includes a connecting frame 11 and fixed frames 12 respectively disposed on both sides of the connecting frame 11, and support frames 13 respectively disposed on the two fixed frames 12. Specifically, the two support frames 13 are arranged laterally and symmetrically to each other. Correspondingly, the bottom of the support frame 13 is provided with support feet 130 for support. The dust suction mechanism 10 is disposed on the connecting frame 11, and the end of the belt conveyor mechanism 2 away from the connecting frame 11 is... At the feeding end, the leather is conveyed from the feeding end of the belt conveyor mechanism 2 to the connecting frame 11. When the leather passes the bottom of the dust suction mechanism 10, the dust suction mechanism 10 is activated. The dust suction mechanism 10 sucks up the dust on the leather, thereby completing the dust removal work on the leather. It should be noted that the dust suction mechanism 10 in this utility model can be a conventional dust suction mechanism 10 that can suck up the dust on the leather, such as the dust suction mechanism disclosed in the Chinese utility model patent with announcement number "CN210945651U" and title "A Leather Dust Removal Device" mentioned in the background art.

[0043] In this invention, the belt conveyor mechanism 2 includes a drive roller 21, a driven roller 22, a support roller 23 located between the drive roller 21 and the driven roller 22, a conveyor belt 24 wound around the drive roller 21, the driven roller 22, and the support roller 23, and a drive mechanism 25 for driving the drive roller 21 to rotate. Specifically, the drive roller 21, the driven roller 22, and the support roller 23 are all horizontally arranged. The two ends of the drive roller 21 are rotatably mounted on two fixed frames 12, and the two ends of the driven roller 22 are rotatably mounted on two support frames 13 at the ends away from the connecting frame 11, that is, the driven roller 22 is located at the feed end of the belt conveyor mechanism 2. The support roller 23 is oscillatingly mounted on the two fixed frames 12. Preferably, in this invention, both sides... The fixed frame 12 is rotatably equipped with a swing block 14 and a swing control mechanism 15 for driving the swing block 14 to swing up and down at one end facing the support frame 13. In this embodiment, the swing control mechanism 15 is preferably a telescopic cylinder. Specifically, the support roller 23 is rotatably arranged at the end of the swing block 14 away from the fixed frame 12. The telescopic cylinder is arranged vertically, with its output end facing upward and hinged to the bottom of the swing block 14. Specifically, the bottom of the swing block 14 has two protruding ears, and the output end of the telescopic cylinder is hinged between the two protruding ears by a pin. The support frame 13 is provided with a corresponding mounting groove 131 for mounting the telescopic cylinder. With this arrangement, controlling the action of the output end of the telescopic cylinder can control the swing of the support roller 23 up and down.

[0044] The swing block 14 is also provided with a first roller adjustment mechanism 16 for adjusting the position of the support roller 23. The first roller adjustment mechanism 16 is correspondingly arranged at both ends of the support roller 23. The first roller adjustment mechanism 16 includes a bearing seat 161 fixed on the swing block 14 and an adjusting bolt 162. The bearing seat 161 has a through hole for the adjusting bolt 162 to extend into and be fixed. The two ends of the support roller 23 are respectively rotatably arranged in the corresponding bearing seat 161. Correspondingly, the swing block 14 is provided with a locking block 141 for fixing the adjusting bolt 162. One end of the bolt 162 is fixed to the locking block 141, and the other end extends into the bearing seat 161 through the through hole and is fixed inside the bearing seat 161. By tightening or loosening the adjusting bolt 162, the position of the bearing seat 161 can be adjusted, thereby adjusting the position of the support roller 23. The first roller adjustment mechanism 16 and the swing control mechanism 16 can better adjust the tension of the conveyor belt 24, thereby adjusting the tension of the belt conveyor mechanism 2. When not in operation, controlling the swing block 14 to drive the support roller 23 to swing downward can also facilitate cleaning the bottom of the dust suction mechanism 10.

[0045] Preferred, such as Figure 3 As shown, the swing block 14 is provided with a first long groove 142 corresponding to the position of the bearing seat 161 of the first roller adjustment mechanism 16. The bearing seat 161 is movably disposed on the first long groove 142. Specifically, the bottom of the bearing seat 161 is provided with a threaded hole. The thread of the bolt fastener is screwed into the bottom of the bearing seat 161 from the bottom of the first long groove 142 to press and fix the bearing seat 161 and the swing block 14. The bolt head of the bolt fastener is stuck at the bottom of the swing block 14, which makes it easy to adjust the position of the support roller 23.

[0046] Preferably, the support frame 13 is further provided with a second roller adjusting mechanism 17 for adjusting the position of the driven roller 22. The second roller adjusting mechanism 17 has the same structure as the first roller adjusting mechanism 16, and correspondingly, both ends of the driven roller 22 are rotatably disposed in the corresponding second roller adjusting mechanism 17; preferably, as Figure 3 As shown, the support frame 13 is provided with a second long groove 132 corresponding to the position of the second roller adjustment mechanism 17. The second roller adjustment mechanism 17 is movably mounted on the second long groove 132, which makes it convenient to adjust the position of the driven roller 22.

[0047] Preferably, guide rollers 133 for guiding the conveyor belt 24 are rotatably provided on the two support frames 13 near the driven roller 22. Specifically, the two guide rollers 133 are arranged facing each other, and the opposite ends of the two guide rollers 133 are inclined downwards. With this arrangement, when the conveyor belt 24 passes over the guide rollers 133, the conveyor belt 24 will continuously move closer to the middle of the two support frames 13 under the guidance of the two guide rollers 133, avoiding the conveyor belt from deviating to the outside of the support frame 13 during the movement, and improving the stability of the conveying.

[0048] Preferably, a plurality of pressing rollers 18 for pressing the conveyor belt 24 are rotatably arranged on the two fixed frames 12. The pressing rollers 18 are arranged parallel to the drive roller 21 and are located between the drive roller 21 and the support roller 23. Specifically, in this embodiment, there are two pressing rollers 18, which are located on both sides of the dust collection mechanism 10. Correspondingly, the bottom horizontal position of the pressing roller 18 is lower than the top horizontal position of the drive roller 21, so that the pressing roller 18 can exert a downward pressing effect on the conveyor belt 24, thereby pressing the leather on the conveyor belt 24. By using the two pressing rollers 18 to flatten the leather, the surface of the leather can be tightened due to the pressing action of the pressing rollers 18 when the leather passes through the bottom of the dust collection mechanism 10, which is conducive to the dust collection mechanism 10 sucking away the dust on the leather, thereby better achieving the purpose of dust removal.

[0049] Preferred, such as Figure 2 As shown, the drive mechanism 25 includes a drive motor 251 fixed on one of the fixed frames 12, and a chain 252 wound around the output end of the drive motor 251 and the drive roller 21. Preferably, a transmission roller 19 is rotatably connected to the end of the fixed frame 12 away from the drive roller 21. The chain 252 is wound around the output end of the drive motor 251, the drive roller 21, and the transmission roller 19. The pressure roller 18 is located between the drive roller 21 and the transmission roller 19. Correspondingly, sprockets 253 are provided on the output end of the drive motor 251, the transmission roller 19, the pressure roller 18, and the drive roller 21. The sprockets on the pressure roller 18 press against the chain 252. Through the cooperation of the sprockets 253 and the chain 252, a relatively stable conveying effect can be achieved.

[0050] Preferably, the support roller 23 has a first guide section 231 at both ends, the diameter of which gradually decreases from the inside to the outside. The driven roller 22 has a second guide section 221 at both ends, the diameter of which gradually decreases from the inside to the outside. Since the diameter of the first guide section 231 is smaller than the diameter of the middle part of the support roller 23 and the diameter of the second guide section 221 is smaller than the diameter of the middle part of the driven roller 22, the conveyor belt 24 will automatically move towards the middle when it is conveyed on the support roller 23 and the driven roller 22. This arrangement ensures that the conveyor belt 24 is always located in the middle of the support roller 23 and the middle of the driven roller 22 during movement, preventing the conveyor belt 24 from shifting to the outer sides of the support frame 13 during movement, and further improving the stability of the conveying.

[0051] This utility model discloses a leather dust removal machine. By setting up a swing block 14 and controlling the swing of the support roller 23 up and down through the swing control mechanism 16, the swing amplitude of the support roller 23 can be controlled to adjust the tension of the belt conveyor mechanism 2, thereby adapting to leather of different weights. This allows the belt conveyor mechanism 2 to stably transport the leather to the dust collection mechanism 10. When not in operation, controlling the downward swing of the support roller 23 can also facilitate cleaning of the bottom of the dust collection mechanism 10. Furthermore, due to the setting of the first roller adjustment mechanism 16, the position of the support roller 23 can be adjusted. The first roller adjustment mechanism 16 and the swing control mechanism 16 can better adjust the tension of the belt conveyor mechanism 2, thereby adapting to leather of different weights and ensuring that the belt conveyor mechanism 2 can stably transport the leather to the dust collection mechanism 10. Compared with the prior art, it has the advantages of good operability and good conveying stability.

[0052] 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.
