An inkjet processing line for artificial stone and its applications

[0001] Cross-reference to related applications

[0002] This application claims priority to Chinese Patent Application No. 202410683035.3, filed on May 30, 2024, entitled "An Inkjet Processing Line for Artificial Stone and Its Use", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This invention relates to the field of artificial stone processing, and more particularly to an inkjet processing line for artificial stone and its applications. Background Technology

[0004] Artificial quartz stone is composed of over 90% natural quartz and approximately 10% colorants, resins, and other additives for bonding and curing. It is a slab produced through a process of negative pressure vacuum molding, high-frequency vibration molding, and heat curing (the temperature depends on the type of curing agent). It is hard (Mohs hardness 5-7) and dense (density 2.3 g / cm³), possessing unparalleled wear resistance, pressure resistance, high-temperature resistance, corrosion resistance, and impermeability compared to other decorative materials.

[0005] In the current processing of artificial quartz stone slabs, inkjet printing is used to improve their aesthetics. However, different artificial quartz stone slabs require different inks, and different inks require different curing methods. For example, some inks cure at room temperature while others require heating. When both curing methods are needed on the production line, some artificial quartz stone slabs may clog subsequent slabs that do not require drying and curing during the drying and curing process, thus reducing the processing efficiency of artificial quartz stone slabs. Summary of the Invention

[0006] The purpose of this invention is to propose an inkjet processing line for artificial stone. The artificial stone is first centered and positioned by a centering device, and then inkjet printed by an inkjet printing device. The artificial stone is then conveyed to a placement mechanism via a drying and heating box and a drying and receiving conveyor assembly at a transition station. The placement mechanism can then receive the artificial stone and output it to the drying and heating box or a cooling device.

[0007] The present invention also proposes the use of an artificial stone inkjet processing line in the inkjet processing of artificial stone, wherein the artificial stone inkjet processing line is the aforementioned artificial stone inkjet processing line.

[0008] To achieve this objective, the present invention adopts the following technical solution:

[0010] The inkjet printing device has inkjet printing function; one of the conveying ends of the centering device faces the inkjet printing device, and the conveying direction of the conveying end is perpendicular to the conveying direction of the other conveying end of the centering device.

[0011] The drying device includes: a drying receiving and conveying assembly, a drying heating chamber, and a placement mechanism;

[0012] The drying and heating chamber has a transition station with open ends. One end of the transition station faces the inkjet printing device, and the other end faces the placement mechanism. The drying and heating chamber has a storage station on the side facing the placement mechanism. The drying material receiving and conveying assembly is located in the transition station. The conveying end inlet of the drying material receiving and conveying assembly is close to the conveying end outlet of the inkjet printing device.

[0013] The placement mechanism includes: a base frame, a lifting frame, a lifting drive assembly, a horizontal drive assembly, and a mold-taking assembly;

[0014] The lifting drive assembly is mounted on the base frame, and its output end is connected to the lifting frame to drive the lifting frame to rise and fall on the base frame, adjusting the lifting frame to pass through the conveying end outlet of the drying receiving conveyor assembly, the storage station, or the conveying end inlet of the cooling device; the horizontal drive assembly is mounted on the lifting frame; the conveying end of the horizontal drive assembly has a horizontal conveying function, and the conveying direction is towards the storage station; the mold taking assembly is equipped with a mold taking device with a gripping function, and the mold taking device can be reset; the mold taking assembly is movably mounted on the lifting frame and moves back and forth between the storage station and the conveying end of the horizontal drive assembly.

Then, an inkjet printing device prints ink on the artificial stone. After passing through a drying and heating chamber, the material is conveyed to a placement mechanism via a drying and receiving conveyor assembly at a transition station. The placement mechanism can either receive the artificial stone and output it to the drying and heating chamber or a cooling device. This allows for flexible selection of drying or direct cooling after inkjet printing of the artificial stone, solving the problem of clogging the processing line caused by the need for drying after inkjet printing of some artificial stones.

[0030] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] As shown in Figure 1-11, an inkjet processing line for artificial stone includes, in sequence along the conveying direction of the artificial stone: a centering device (1), an inkjet printing device (2), a drying device (3), and a cooling device (4).

[0032] The inkjet printing device (2) has an inkjet printing function; one of the conveying ends of the centering device (1) is oriented toward the inkjet printing device (2), and the conveying direction of the conveying end is perpendicular to the conveying direction of the other conveying end of the centering device (1).

[0033] The drying device (3) includes: a drying receiving and conveying assembly (31), a drying heating box (32), and a placement mechanism (33);

[0034] The drying and heating box (32) is provided with a transition station (3201) with open ends. One end of the transition station (3201) faces the inkjet printing device (2); the other end of the transition station (3201) faces the placement mechanism (33). The drying and heating box (32) is provided with a storage station (3202) on the side facing the placement mechanism (33). The drying receiving and conveying assembly (31) is located in the transition station (3201). The conveying end inlet of the drying receiving and conveying assembly (31) is close to the conveying end outlet of the inkjet printing device (2).

[0035] The placement mechanism (33) includes: a base frame (331), a lifting frame (332), a lifting drive assembly (333), a horizontal drive assembly (334), and a mold taking assembly (335);

[0036] The lifting drive assembly (333) is installed on the base frame (331), and the output end of the lifting drive assembly (333) is connected to the lifting frame (332) for driving the lifting frame (332) to rise and fall on the base frame (331), so that the lifting frame (332) is adjusted to pass through the conveying end outlet of the drying receiving conveyor assembly (31), the storage station (3202), or the conveying end inlet of the cooling device (4); the horizontal drive assembly (334) is installed on the base frame (331). The lifting frame (332) has a horizontal conveying function at the conveying end of the horizontal drive assembly (334), and the conveying direction is toward the storage station (3202). The mold taking assembly (335) is provided with a mold taking device (3351) with a gripping function, and the mold taking device (3351) is repositionable. The mold taking assembly (335) is movably installed on the lifting frame (332) and moves back and forth between the storage station (3202) and the conveying end of the horizontal drive assembly (334).

[0037] This solution provides an inkjet processing line for artificial stone. First, the artificial stone is centered and positioned by a centering device (1). Then, the artificial stone is inkjet printed by an inkjet printing device (2). After passing through a drying and heating box (32), the artificial stone is conveyed to a placement mechanism (33) via a drying and receiving conveyor assembly (31) at a transition station (3201). The placement mechanism (33) can either receive the artificial stone and output it to the drying and heating box (32) or a cooling device (4). This allows for flexible selection of drying or direct cooling after inkjet printing of the artificial stone, solving the problem of clogging the processing line caused by the need for drying after inkjet printing of some artificial stones.

[0038] In this scheme, the artificial stone can be directly conveyed into the processing line or conveyed by a pallet; as shown in Figure 1, the arrow indicates the conveying direction of the artificial stone; the artificial stone is input to the centering device (1); the centering device (1) has two conveying ends, one of which faces the inkjet printing device (2) and can be used to output the artificial stone to the inkjet printing device (2); while the other conveying end of the centering device (1) is perpendicular to the conveying direction of the artificial stone, and this conveying end can be used to center the artificial stone, so that the artificial stone enters the inkjet printing device (2) in the best position, and based on the position after centering, it passes through the drying receiving conveyor assembly (31) and the placement mechanism (33) in sequence, and then by the placement mechanism (33) Set in a drying heating box (32) or a cooling device (4); wherein, the drying heating box (32) is provided with a transition station (3201) with open ends, one end of the transition station (3201) is connected to the inkjet printing device (2), and the drying receiving conveyor assembly (31) can receive artificial stone at this end of the transition station (3201); the conveying end of the placement mechanism (33) can pass vertically through the other end of the transition station (3201) after the lifting adjustment, thereby receiving the artificial stone from the drying receiving conveyor assembly (31); after the placement mechanism (33) receives the artificial stone, it can output it to the drying heating box (32) for drying according to the processing needs of the artificial stone, or it can be directly output to the cooling device. The artificial stone is placed in the cooling device (4) for cooling treatment, or it can be dried in the drying heating box (32) before being output to the cooling device (4); more specifically, when it is necessary to store the artificial stone, the lifting drive assembly (333) can be activated, the lifting drive assembly (333) can drive the lifting frame (332) to move to the height position for receiving the artificial stone, and the artificial stone can be placed manually or by using the horizontal drive assembly (334) to place the artificial stone in the middle of the lifting frame (332), and then the lifting drive assembly (333) can be activated to drive the lifting frame (332) to move to the empty storage station (3202); subsequently, the horizontal drive assembly (334) can be activated, the horizontal drive assembly (334) can drive the artificial stone to the storage station (3202) The artificial stone is placed in the storage station (3202) by forward conveying. When the artificial stone needs to be removed, the lifting drive component (333) drives the lifting frame (332) to move to the required height position of the artificial stone, and starts the mold taking component (335). The mold taking component (335) moves horizontally to the position of the artificial stone and activates the mold taking device (3351) with the gripping function. The mold taking device (3351) grabs the artificial stone. Under the action of the return stroke of the mold taking component (335), the artificial stone is transferred to the conveying end of the horizontal drive component (334) in the lifting frame (332), and under the action of the reverse conveying of the horizontal drive component (334), the artificial stone is driven out, thereby realizing the removal of the artificial stone from the box (321).

[0039] In this way, artificial stone can be dried or cooled after inkjet printing. If artificial stone needs to be dried, the conveying end of the placement mechanism (33) only needs to be reversed to the storage station (3202) of the drying heating box (32). Since the conveying end of the placement mechanism (33) moves away from the drying heating box (32) when it is conveyed in the forward direction, the drying of artificial stone will not interfere with the entry of other artificial stone into the cooling device (4), thereby avoiding the problem of artificial stone blocking the processing line during the drying process. Thus, the drying heating box (32) and the cooling device (4) can be used flexibly on the processing line. The use of the drying device (3) and the cooling device (4) does not interfere with each other, improving the processing efficiency of the artificial stone inkjet processing line.

[0040] Among them, the conveying end of the inkjet printing device (2), the conveying end of the centering device (1), the conveying end of the drying receiving conveyor assembly (31), and the conveying end of the placement mechanism (33) refer to the main mechanisms that realize linear movement. For example, they can be realized by known mechanisms that have the function of driving linear movement, such as conveyor belt structure, conveyor roller structure, combination of gears and chains, moving trolley, cylinder, hydraulic cylinder, robotic arm, or combination of motor and lead screw. The conveying end inlet refers to the position where the artificial stone enters the conveying end; the conveying end outlet refers to the position where the artificial stone is output from the conveying end.

[0041] The lifting drive assembly (333) can be replaced by a known mechanism with a lifting function, such as a cylinder, hydraulic cylinder, a combination of a motor and a lead screw, or a robotic arm, as long as it enables the lifting frame (332) to move up and down relative to the base frame (331). The horizontal drive assembly (334) can be replaced by a known mechanism with a horizontal movement function, such as a cylinder, hydraulic cylinder, a moving trolley, a conveyor roller structure, or a conveyor belt structure, as long as it enables the artificial stone to move horizontally relative to the lifting frame (332). The horizontal movement of the mold-taking assembly (335) on the lifting frame (332) can also be achieved by a known mechanism with a horizontal movement function, such as a cylinder, hydraulic cylinder, a moving trolley, a conveyor roller structure, or a conveyor belt structure, as long as it enables the mold-taking assembly (335) to move horizontally relative to the lifting frame (332). The mold taker (3351) can be replaced by a known mechanism with a gripping function, such as a clamp, a gripper, or a robotic arm.

[0042] Optimally, the drying and heating box (32) includes: a box body (321), a heating air duct assembly (322), and an air guide plate (323);

[0043] The housing (321) is provided with a drying and storage chamber (3211) and an air inlet chamber (3212); the drying and storage chamber (3211) and the air inlet chamber (3212) are separated by an air inlet partition (3213);

[0044] The heating air duct assembly (322) includes: a heating air inlet duct (3221) and an air inlet heating device (3222);

[0045] The output end of the heating air inlet pipe (3221) is connected to one end of the air inlet cavity (3212) along its length; the output end of the air inlet cavity (3212) is located on the air inlet baffle (3213); the output ends of the plurality of air inlet cavities (3212) extend along the length of the air inlet baffle (3213) and are connected to the drying storage cavity (3211); the air inlet heating device (3222) has a heating function and is disposed on the heating air inlet pipe (3221);

[0046] The air guide plate (323) is disposed in the air inlet cavity (3212), one end of the air guide plate (323) is located at one end of the air inlet cavity (3212) in the length direction, and the other end of the air guide plate (323) is located at the other end of the air inlet cavity (3212) in the length direction; an air guide channel (3214) is formed between the air inlet baffle (3213) and the air guide plate (323), and the inner diameter of the air guide channel (3214) gradually decreases in the direction away from the heating air inlet pipe (3221).

[0047] This solution provides a drying and heating box in which an air guide plate (323) is set in the air inlet cavity (3212) that connects to the drying and storage cavity (3211). By changing the inner diameter of the air inlet cavity (3212) through the air guide plate (323), the inner diameter of the air guide channel (3214) is gradually reduced, thereby changing the flow rate of the airflow when it is conveyed along the length direction of the air inlet cavity (3212), thereby gradually increasing the flow rate of the airflow, so that the gas enters the drying and storage cavity (3211) almost synchronously along the length direction of the air inlet baffle (3213), making the drying and storage cavity (3211) more uniform during drying, and solving the problem that the existing drying and heating box is prone to uneven drying when the gas enters from one side.

[0048] Specifically, the housing (321) is provided with a drying and storage chamber (3211) and an air inlet chamber (3212); the drying and storage chamber (3211) is the main drying area, and it can be equipped with structures such as supports, trays, and rollers for supporting the dried items; as shown in Figure 6, the air inlet chamber (3212) is a chamber for outputting heated gas to the drying and storage chamber (3211); one end of the air inlet chamber (3212) is connected to the heating air inlet pipe (3221) in the length direction, and the heating air inlet pipe (3221) outputs gas to the air inlet chamber (3212). After the gas passes through the air inlet heating device (3222), it enters the air inlet. The heating device (3222) heats the gas, thereby heating the gas and outputting it to the air inlet cavity (3212); the air inlet cavity (3212) is also equipped with a guide plate (323), which extends obliquely along the length of the air inlet cavity (3212), that is, one end of the guide plate (323) is located at one end of the air inlet cavity (3212) in the length direction, and the other end of the guide plate (323) is located at the other end of the air inlet cavity (3212) in the length direction; the guide plate (323) in the air inlet cavity (3212) can change the inner diameter of the air inlet cavity (3212). (323) and the air inlet baffle (3213) form an air guide channel (3214), and the inner diameter of the air guide channel (3214) gradually decreases in the direction away from the heating air inlet pipe (3221). Since the air guide channel (3214) is connected to the heating air inlet pipe (3221), the heating gas in the heating air inlet pipe (3221) is heated and then output to the air guide channel (3214). Based on the constant airflow rate, the inner diameter of the air guide channel (3214) gradually decreases in the direction away from the heating air inlet pipe (3221), and the airflow velocity gradually increases along the length of the air inlet cavity (3212). This allows the airflow to quickly pass through the output ends of multiple air inlet chambers (3212) of the air inlet baffle (3213), and then be output to the drying and storage chamber (3211) through the output ends of multiple air inlet chambers (3212). This allows the airflow to be output to the drying and storage chamber (3211) almost synchronously along the length of the air inlet baffle (3213). The airflow is output to multiple positions in the drying and storage chamber (3211) almost simultaneously rather than concentrated in a local position, which further improves the heating uniformity of the airflow and solves the problem of uneven drying caused by the existing drying and heating box entering the box from one side.

[0049] The air inlet heating device (3222) is a known heating mechanism, such as resistance wire heating, electromagnetic heating, or water bath heating. The output end of the air inlet chamber (3212) is a structure that outputs gas, such as a through hole, through groove, or nozzle.

[0050] Optimally, the air inlet chamber (3212) is disposed on at least two sides of the drying and storage chamber (3211), and each air inlet chamber (3212) is connected to a heating air inlet pipe (3221);

[0051] The air intake heating device (3222) is divided into a resistance heating device (32221) and a gas heating device (32222); the number of air intake chambers (3212) is 2; the resistance heating device (32221) is installed in the heating air intake pipe (3221) connected to one of the air intake chambers (3212), and the gas heating device (32222) is installed in the heating air intake pipe (3221) connected to the other air intake chamber (3212).

[0052] This solution provides air inlet chambers (3212) on multiple sides of the drying and storage chamber (3211). Each air inlet chamber (3212) is connected to a heating air inlet pipe (3221). When heating gas enters from multiple sides of the drying and storage chamber (3211), the heating gas can enter from multiple sides of the drying and storage chamber (3211) almost simultaneously along the length of the air inlet chamber (3212) based on the air guide channel (3214) provided in the air inlet chamber (3212), thereby further improving the drying uniformity of the drying and storage chamber (3211).

[0053] The air inlet heating device (3222) can be divided into two types according to needs: resistance heating device (32221) and gas heating device (32222). The resistance heating device (32221) uses electric current to generate heat through a conductive material to heat the gas input into the air inlet pipe (3221), and has high heating stability. The gas heating device (32222) uses combustible gas to heat the gas, generating high heat, and is suitable for processes with high drying degree and fast drying speed.

[0054] The heating air duct assembly (322) includes: an air intake duct (3223) and an exhaust device (3224);

[0055] One of the output ends of the suction pipe (3223) is connected to the heating air inlet pipe (3221) where the resistance heating device (32221) is located, and the other output end of the suction pipe (3223) is connected to the heating air inlet pipe (3221) where the gas heating device (32222) is located; the exhaust device (3224) is installed on the suction pipe (3223).

[0056] This solution preferably uses a single suction pipe (3223) to simultaneously output airflow to two heating air inlets (3221), that is, the two heating air inlets (3221) share a single exhaust device (3224). One of the output ends of the suction pipe (3223) can be opened as needed, so that air is sent into the suction pipe (3223) under the negative pressure of the exhaust device (3224) and transferred to the corresponding heating air inlet (3221), and then output from the heating air inlet (3221) to the air guide channel (3214), thereby simplifying the number and structure of the air inlets.

[0057] The drying and heating box (32) also includes: an elastic buffer (324);

[0058] The elastic buffer (324) is provided with a buffer fixing part (3241) and a buffer elastic part (3242);

[0059] The buffer fixing part (3241) is installed in the drying storage cavity (3211); the buffer elastic part (3242) is suspended; the buffer elastic part (3242) is elastic and has a buffer arc surface (3243).

[0060] When an object is placed in the drying storage chamber (3211), the elastic buffer (324) provides a cushioning effect as the object moves into the drying storage chamber (3211). The object's endpoint in the drying storage chamber (3211) abuts against the elastic buffer (324). The elastic buffer (324) has two parts: a buffer fixing part (3241) and a buffer elastic part (3242). The buffer fixing part (3241) is used to fix the position of the elastic buffer (324) in the drying storage chamber (3211). The buffer elastic part... (3242) is suspended and the elastic buffer (324) is elastic. The material used can be metal, plastic or rubber and other materials with a certain degree of elasticity. Since the buffer elastic part (3242) is suspended, when the object moves to the buffer elastic part (3242), the buffer elastic part (3242) can deform elastically. The deformation of the buffer elastic part (3242) slows down the speed at which the object enters the drying storage cavity (3211) and avoids the object moving too fast and impacting the inside of the drying storage cavity (3211).

[0061] The drying and storage chamber (3211) has multiple storage stations (3202) along its height direction, and the elastic buffer (324) is provided in each storage station (3202). The drying and storage chamber (3211) has multiple storage stations (3202) along its height direction, allowing items to be arranged along the height of the drying and storage chamber (3211). The airflow output from the air inlet chamber (3212) can be output along the length of the storage station (3202), thus ensuring uniform heating of the entire storage station (3202).

[0062] The air inlet chamber (3212) is provided with a drying air outlet (3215) at its output end; the drying air outlet (3215) is distributed along the length and height of the air inlet baffle (3213) and is correspondingly connected to the storage station (3202).

[0063] An air inlet baffle (3213) is provided at the output end of the air inlet cavity (3212). The air inlet baffle (3213) is provided with multiple drying air outlets (3215). The drying air outlets (3215) are distributed along the height direction of the air inlet baffle (3213), so that one drying air outlet (3215) corresponds to one storage station (3202), thereby outputting gas to different storage stations (3202). When gas is input into the air inlet cavity (3212), it is accelerated and output from the drying air outlets (3215) along the length direction of the baffle to different positions of the storage station (3202), so that the length direction of a single storage station (3202) is close to the gas contact at the same time, thereby improving the heating uniformity of each storage station (3202).

[0064] The drying and heating chamber (32) further includes a dehumidification device (325); the dehumidification device (325) is connected to the drying and storage chamber (3211).

[0065] In addition to heating the drying storage chamber (3211) through the heating network tube assembly, this solution also preferably uses a dehumidification device (325) to extract the air from the drying storage chamber (3211) first, so that the humidity in the drying storage chamber (3211) reaches the specified value, and then starts the heating air duct assembly (322), thereby greatly improving the drying effect.

[0066] The drying and storage chamber (3211) is equipped with storage wheels (326); the storage wheels (326) are arranged along the height direction of the drying and storage chamber (3211), and a storage station (3202) is formed between two vertically adjacent storage wheels (326). The storage wheels (326) can be installed in the drying and storage chamber (3211), and a storage station (3202) is formed between two vertically adjacent storage wheels (326) to separate them into different storage stations (3202); at the same time, the storage wheels (326) can also contact the bottom of the object, so that when the object enters or exits the storage station (3202), the storage wheels (326) provide a rolling action, which improves the smoothness of the object entering and exiting the storage station (3202).

[0067] Optimally, it also includes: a pretreatment device (5); the pretreatment device (5), the centering device (1), the inkjet printing device (2), the drying device (3) and the cooling device (4) are arranged in sequence; the pretreatment device (5) is provided with a pretreatment chamber (51), and a pretreatment heating mechanism and a cleaning mechanism are also provided in the pretreatment chamber (51).

[0068] The pretreatment chamber (51) is equipped with a pretreatment heating mechanism, which can be used to heat the artificial stone to a certain temperature. This prevents the artificial stone from being too cold when it enters the inkjet printing device (2), which would affect the physical and chemical properties of the ink and ensure that the ink can be printed at the optimal temperature. The impurity removal mechanism is mainly used to clean the surface of the artificial stone to keep it clean and prevent the ink from being applied to impurities. For example, it removes dust from the surface of the artificial stone by using negative pressure.

[0123] The horizontal drive seat (3341) is mounted on both sides of the lifting frame (332); the horizontal drive wheel (3342) and the horizontal driven wheel (3343) are rotatably mounted on the horizontal drive seat (3341); the horizontal synchronous belt (3344) connects the horizontal drive wheel (3342) and the horizontal driven wheel (3343) to rotate synchronously, and the horizontal synchronous belt (3344) extends along the length direction of the horizontal drive seat (3341); the output end of the horizontal driver (3345) is connected to the horizontal drive wheel (3342) and is used to drive the horizontal drive wheel (3342) to rotate, thereby driving the horizontal driven wheel (3343) to rotate.

[0124] The bearing seat (3346) is installed in the middle of the lifting frame (332); a plurality of the transmission shafts (3347) are installed on the bearing seat (3346); a plurality of the transmission wheels (3348) are installed on the transmission shafts (3347).

[0125] This solution can preferably use a horizontal synchronous belt (3344) to drive the mold conveying; specifically, the horizontal drive seat (3341) is installed on both sides of the lifting frame (332), the horizontal drive wheel (3342) and the horizontal driven wheel (3343) are respectively installed on the horizontal drive seat (3341), and the horizontal synchronous belt (3344) connects the horizontal drive wheel (3342) and the horizontal driven wheel (3343) to rotate synchronously. When the horizontal driver (3345) is started, the output end of the horizontal driver (3345) drives the horizontal drive wheel (3342) to rotate. Under the synchronous action of the horizontal synchronous belt (3344), the horizontal driven wheel (3343) rotates, and the horizontal synchronous belt (3344) rotates, thereby causing the mold placed on the surface of the horizontal synchronous belt (3344) to move back and forth to the storage station (3202).

[0126] Here, the horizontal driving wheel (3342) and the horizontal driven wheel (3343) can be ordinary rotating wheels, and the horizontal synchronous belt (3344) is an ordinary synchronous belt; further optimized, the horizontal driving wheel (3342) and the horizontal driven wheel (3343) can be gears, and the horizontal synchronous belt (3344) is a synchronous chain, which meshes with the horizontal driving wheel (3342) and the horizontal driven wheel (3343) respectively.

[0127] In one embodiment, the bottom of the mold is placed directly on the horizontal synchronous belt (3344), and the mold is moved by the horizontal synchronous belt (3344). In the optimal embodiment, the horizontal drive seat (3341) is installed on both sides of the lifting frame (332), and the bearing seat (3346) is installed in the middle of the lifting frame (332). The transmission wheel (3348) is used to support the bottom of the mold inside both sides. The mold is supported by the horizontal synchronous belt (3344) on both sides. The horizontal synchronous belt (3344) drives the mold to be transmitted to the lifting frame (332) under the action of rotation. The mold moves relative to the transmission wheel (3348), thereby reducing the pressure on the horizontal synchronous belt (3344) and the load on the horizontal synchronous belt (3344) is smaller.

[0128] The mold-taking assembly (335) moves between two adjacent shaft seats (3346); the mold-taking device (3351) is repositionably movable to extend above the transfer wheel (3348).

[0129] The mold-grabbing assembly (335) is located in the middle of the lifting frame (332), specifically between the bearing seats (3346). It can grab the mold in the middle by the mold grabber (3351). At the same time, the mold grabber (3351) is disengaged from the conveyor wheel (3348) in one of its active states, and will not grab the mold in this state. When the mold-grabbing assembly (335) moves to the nearest storage station (3202), the mold grabber (3351) extends out above the conveyor wheel (3348) in another active state, thereby grabbing the mold and being driven to move by the mold-grabbing assembly (335). The mold-grabbing assembly (335) moves to a position away from the storage station (3202), thereby placing the mold on the conveyor wheel (3348), and the mold is then driven out by the horizontal synchronous belt (3344).
