Description

Technical Field

[0001] This utility model relates to the field of compression molding machine technology, specifically to an automatic feeding lithium slag compression molding machine. Background Technology

[0002] With the rapid development of the lithium battery industry, the resource utilization of lithium slag, a solid waste generated during lithium salt production or the recycling of used lithium batteries, has gradually gained attention. Lithium slag can be pressed and molded into building bricks or other industrial products with certain strength and stability, thus realizing the reuse of solid waste. In this process, the automatic feeding and uniform distribution of lithium slag become key factors affecting molding quality and production efficiency.

[0003] Currently, traditional lithium slag pressing and molding equipment mostly uses free-falling material feeding into the receiving frame, lacking an effective material distribution mechanism. This results in material accumulating in the middle of the receiving frame while the edge areas are not filled enough, causing uneven stress during the pressing process. This affects the consistency of the density and strength of the finished product, and may even lead to defects such as cracking and missing corners. Therefore, an automatic feeding lithium slag pressing and molding machine is needed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an automatic feeding lithium slag pressing and molding machine, which has the advantages of automatic and uniform material distribution, continuous feeding and high-efficiency pressing, and solves the problems of uneven material feeding, low production efficiency and unstable molding quality of existing equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding lithium slag pressing and molding machine, comprising a pressing machine body, wherein a feeding mechanism is provided on the side end face of the pressing machine body;

[0006] The main body of the press includes a receiving frame, a first cylinder, a second cylinder, a pressing mold, a third cylinder, a bottom pressing plate, and an equipment frame. The first cylinder, the second cylinder, and the third cylinder are fixedly installed on the equipment frame. The receiving frame is installed on the telescopic shaft of the first cylinder. The pressing mold is fixedly installed on the telescopic shaft of the second cylinder. The bottom pressing plate is fixedly installed on the output shaft of the third cylinder. The feeding mechanism includes a feeding hopper, a conveyor belt, and a transfer hopper. The feeding hopper is installed on the conveyor belt. The transfer hopper is located below the conveyor belt. A material distribution plate is provided at the bottom of the inner end face of the transfer hopper. The receiving frame is located at the lower end of the transfer hopper.

[0007] As a preferred embodiment of the automatic feeding lithium slag pressing and molding machine of this utility model, the side end face of the material distribution plate is provided with a Z-shaped shaft, the material distribution plate is rotatably connected to the central transfer bucket through the Z-shaped shaft, and the top of the Z-shaped shaft is provided with a rotatably connected connecting rod.

[0008] As a preferred embodiment of the automatic feeding lithium slag pressing and molding machine of this utility model, a second motor is fixedly installed on the back of the transfer bucket, and a cam that fits with the connecting rod is provided on the output shaft of the second motor.

[0009] As a preferred embodiment of the automatic feeding lithium slag pressing and molding machine of this utility model, a slide rod is fixedly connected to the end of the connecting rod away from the cam, a sleeve is slidably connected to the outer end of the slide rod, a spring is provided inside the sleeve, and a baffle is fixedly connected to the back of the transfer bucket.

[0010] As a preferred embodiment of the automatic feeding lithium slag pressing and molding machine of this utility model, the sleeve is provided with universal ball bearings near the baffle end.

[0011] As a preferred embodiment of the automatic feeding lithium slag pressing and molding machine of this utility model, the connecting rod is provided with a rotatably connected pulley near the cam end.

[0012] As a preferred embodiment of the automatic feeding lithium slag pressing and molding machine of this utility model, the lower end of the transfer bucket is provided with a slidingly connected insert plate, the equipment frame is provided with a fourth cylinder, and the insert plate is fixedly installed on the telescopic shaft of the third cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model solves the problem of uneven accumulation of lithium slag by cooperating the material distribution plate in the transfer hopper with the Z-shaped shaft linkage mechanism and the cam structure driven by the second motor. The material distribution plate swings synchronously left and right through the Z-shaped shaft under the periodic push of the cam, so that the lithium slag falls alternately to both sides of the receiving frame. This structure avoids the problem of excessive material accumulation in the middle of the receiving frame caused by traditional free falling, and ensures uniform material distribution. At the same time, the process of continuous material receiving in the transfer hopper and periodic removal of the receiving frame from the pressing process allows the equipment to receive new material during the pressing process, which greatly shortens the production cycle and significantly improves the efficiency of continuous operation.

[0015] 2. This utility model utilizes a combination structure of an elastic telescopic rod composed of a slide rod, a sleeve, and a spring, along with universal ball bearings. When the short shaft end of the cam turns towards the connecting rod, the spring pushes the sleeve to extend and retract along the slide rod, ensuring that the connecting rod always fits tightly against the cam profile. This prevents operational failure due to inertial disengagement. Simultaneously, the pulley design at the end of the connecting rod converts the sliding friction of the cam contact surface into rolling friction. Combined with the point contact support of the universal ball bearings at the end of the sleeve on the baffle, this significantly reduces frictional resistance during the oscillation process. This dual friction-reducing structure ensures the smoothness of the high-frequency oscillation of the material distribution plate, reduces mechanical wear, and is particularly suitable for long-term operation in lithium slag dust environments, extending the service life of core moving parts.

[0022] Please see Figures 1-5 An automatic feeding lithium slag pressing and molding machine includes a pressing machine body 2, and a feeding mechanism 1 is provided on the side end face of the pressing machine body 2.

[0023] The main body 2 of the press machine includes a receiving frame 201, a first cylinder 202, a second cylinder 203, a pressing mold 204, a third cylinder 205, a bottom pressing plate 206, and an equipment frame 207. The first cylinder 202, the second cylinder 203, and the third cylinder 205 are fixedly installed on the equipment frame 207. The receiving frame 201 is installed on the telescopic shaft of the first cylinder 202. The pressing mold 204 is fixedly installed on the telescopic shaft of the second cylinder 203. The bottom pressing plate 206 is fixedly installed on the output shaft of the third cylinder 205. The feeding mechanism 1 includes a feeding hopper 101, a conveyor belt 102, and a transfer hopper 104. The feeding hopper 101 is installed on the conveyor belt 102. The transfer hopper 104 is located below the conveyor belt 102. A material distribution plate 107 is provided at the bottom of the inner end face of the transfer hopper 104. The receiving frame 201 is located at the lower end of the transfer hopper 104.

[0024] Lithium slag is fed into the feeding hopper 101. The first motor 103 drives the drive roller 108 to rotate, thereby driving the conveyor belt 102 to continuously feed the lithium slag into the transfer hopper 104. The lithium slag falls into the receiving frame 201 through the transfer hopper 104. The first cylinder 202 pushes the transfer hopper 104 to the lower end of the pressing mold 204, thereby causing the second cylinder 203 to drive the pressing mold 204 to press down for molding. Then, the second cylinder 203 and the third cylinder 205 slide down synchronously, so that the molded brick slides down with the bottom pressing plate 206 and separates from the receiving frame 201. After the brick is removed, the second cylinder 203 and the third cylinder 205 reset, and then the first cylinder 202 resets. The transfer hopper 104 is equipped with a distribution plate 107, which makes the lithium slag fall evenly into the receiving frame 201 to avoid local accumulation that would affect the molding effect.

[0025] Furthermore, a Z-shaped shaft 109 is provided on the side end face of the material distribution plate 107. The material distribution plate 107 is rotatably connected to the transfer bucket 104 through the Z-shaped shaft 109. A connecting rod 110 is provided on the top of the Z-shaped shaft 109 for rotatable connection.

[0026] The connecting rod 110 and the Z-shaped shaft 109 work together to make the two batching plates 107 swing left and right synchronously, so that the lithium slag is fed out alternately from left to right with the batching plates 107, avoiding the middle of the receiving frame 201 from being too high.

[0027] Furthermore, a second motor 112 is fixedly installed on the back of the transfer bucket 104, and a cam 111 that fits against the connecting rod 110 is provided on the output shaft of the second motor 112.

[0028] The motor drives the cam 111 to rotate, which in turn causes the cam 111 to intermittently press the connecting rod 110, causing the material distribution plate 107 to swing left and right, thus achieving automatic material distribution.

[0029] Furthermore, a slide rod 115 is fixedly connected to the end of the connecting rod 110 away from the cam 111. A sleeve 114 is slidably connected to the outer end of the slide rod 115. A spring 116 is installed inside the sleeve 114. A baffle 113 is fixedly connected to the back of the transfer bucket 104.

[0030] The elastic telescopic rod, consisting of slide rod 115, sleeve 114 and spring 116, pushes the connecting rod 110 so that the connecting rod 110 can still be in contact with the short axis of cam 111.

[0031] Furthermore, a universal ball bearing 117 is provided at the end of the sleeve 114 near the baffle 113.

[0032] The friction between the sleeve 114 and the baffle 113 is reduced by the universal ball bearing 117, which improves the smoothness of the swing of the material distribution plate 107, reduces the wear of the sleeve 114, and extends the service life of the equipment.

[0033] Furthermore, a pulley 118 is provided on the end of the connecting rod 110 near the cam 111 for rotational connection.

[0034] By reducing the friction between the connecting rod 110 and the cam 111 through the pulley 118, the smoothness of the oscillation of the material distribution plate 107 is further improved, and the wear of the cam 111 and the connecting rod 110 is reduced, thus extending the service life of the equipment.

[0035] Furthermore, the lower end of the transfer bucket 104 is provided with a slidingly connected insert plate 106, and the equipment frame 207 is provided with a fourth cylinder 105. The insert plate 106 is fixedly installed on the telescopic shaft of the third cylinder 205.

[0036] When the receiving frame 201 is full, the fourth cylinder 105 pushes the insert plate 106 to insert into the discharge port of the transfer bucket 104, briefly blocking the discharge port. After pressing and forming, the insert plate 106 is pulled back, and the receiving frame 201 continues to receive materials.

[0037] When using this pressing and molding machine, lithium slag is first fed into the feeding hopper 101, and the first motor 103 is started. The first motor 103 drives the drive roller 108 to rotate, thereby driving the conveyor belt 102 to continuously transport lithium slag to the transfer hopper 104. The lithium slag falls into the receiving frame 201 through the transfer hopper 104. Under the action of the cam 111 driven by the second motor 112, the distribution plate 107 in the transfer hopper 104 swings left and right in cooperation with the Z-shaped shaft 109, connecting rod 110, slide rod 115, sleeve 114, spring 116 and other components, so that the lithium slag is fed alternately from left to right with the distribution plate 107 and falls evenly into the receiving frame 201 to avoid excessive accumulation in the middle. When the receiving frame 201 is full, the fourth cylinder 105 on the equipment frame 207 pushes the insert plate 106 to insert. The discharge port of the transfer bucket 104 is briefly blocked to pause feeding. Then, the first cylinder 202 pushes the receiving frame 201 to the lower end of the pressing mold 204. Subsequently, the second cylinder 203 drives the pressing mold 204 to press down and shape the lithium slag. After shaping, the second cylinder 203 and the third cylinder 205 slide down synchronously, causing the shaped brick to slide down with the bottom pressing plate 206 and separate from the receiving frame 201. At this time, the brick can be removed. After the brick is removed, the second cylinder 203 and the third cylinder 205 reset, and then the first cylinder 202 resets again. The fourth cylinder 105 pulls back the insert plate 106, and the discharge port of the transfer bucket 104 reopens. The receiving frame 201 continues to receive material. This cycle is repeated to achieve continuous automatic feeding and pressing of lithium slag.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
