Description

Technical Field

[0001] The present invention relates to the field of calendering technology, and in particular to a sheet receiving mechanism of a PVC sheet calendering device. Background Art

[0002] PVC sheets are sheet materials mainly made of polyvinyl chloride (PVC). They have good corrosion resistance, insulation properties, certain mechanical strength and processing performance, and are widely used in fields such as packaging, decoration, advertising, building materials, etc. Calendering is an important method for plastic processing. During the calendering process, plastic materials are extruded and extended through a series of heated rollers to form continuous sheet-like or film-like products. After the production of PVC sheets by calendering is completed, according to special requirements, they are cut into single sheets, and the cut sheets are neatly stacked, and then packaged. The existing sheet receiving mechanism only positions the sheets through two groups of baffles. During the sheet receiving process, in order to stack the sheets neatly, manual assistance is required to position and press the sheets. Moreover, after the sheets reach the specified quantity, manual labor is needed to move the sheets away and package them. It is easy to have situations such as missing records or incorrect records when manually counting the quantity of received sheets, resulting in inaccurate quantities. As a result, when packaging, the quantity of sheets needs to be counted again, thus reducing work efficiency. Also, when moving and packaging the stacked sheets with the specified quantity, vibrations or unstable factors during the moving process are likely to cause the originally neatly stacked sheets to become scattered, requiring re-arrangement, which increases unnecessary processes.

[0031] In the following description, many specific details are set forth to facilitate a thorough understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0032] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0033] Embodiment 1

[0034] Refer to Figure 2 , Figure 6 , Figure 7 and Figure 8, which is the first embodiment of the present invention. This embodiment provides a material receiving mechanism for a PVC sheet calendering device. The material receiving mechanism of the PVC sheet calendering device includes a material receiving assembly 200, which includes a positioning frame 201a, a support plate 201b, a connecting plate 201c, a fixed shaft 201d, a support block 201e, a support column 201f, a first spring 201g, a pressing plate 201h, a support shaft 201i, and a positioning block 201j. The support plate 201b is located inside the positioning frame 201a. The connecting plate 201c is arranged on one side of the support plate 201b. One end of the fixed shaft 201d is fixed to the connecting plate 201c, and the other end is inserted into the support plate 201b and is movably connected to the inside of the support plate 201b. One side of the support block 201e is fixed to the positioning frame 201a. The support column 201f is fixed to the top of the support block 201e. The support column 201f is movably connected to the inside of the connecting plate 201c. The two ends of the first spring 201g are respectively fixed to the connecting plate 201c and the support block 201e. The pressing plate 201h is arranged on the top of the positioning frame 201a. The support shaft 201i is fixed to the inner side of the pressing plate 201h. The positioning block 201j is fixed to one side of the positioning frame 201a. The support shaft 201i is rotatably connected to the inside of the positioning block 201j.

[0035] There are two support plates 201b, which are respectively located on both sides inside the positioning frame 201a. The cut PVC sheets are supported by the support plates 201b, and the PVC sheets are positioned by the positioning frame 201a. In this way, the PVC sheets can be stacked neatly, and there is no need for manual auxiliary positioning of the PVC sheets. The number of connecting plates 201c is the same as that of the support plates 201b. The support plates 201b are connected to the connecting plates 201c through the fixed shafts 201d. Two fixed shafts 201d are respectively fixed on both sides of one support plate 201b.

[0036] Baffles are fixed on both sides of the top of the positioning frame 201a to block the falling PVC sheets and prevent them from falling outside the positioning frame 201a. An inclined diversion plate is fixed on the side of the baffle close to the cutting device 102. The falling PVC sheets are guided by the diversion plate to completely enter the positioning frame 201a.

[0037] The support column 201f is used to position the connecting plate 201c to prevent it from shifting during movement. The connecting plate 201c is supported by the first spring 201g so that it can be in a relatively high position. At this height, the cut PVC sheets can accurately fall onto the top of the support plate 201b and be located inside the positioning frame 201a. The number of support blocks 201e, support columns 201f, and first springs 201g is four, which are respectively located at the four corners of the positioning frame 201a.

[0038] There are two pressing plates 201h, which are respectively located on both sides of the top of the positioning frame 201a. The pressing plates 201h are L-shaped. The cooperation between the support shaft 201i and the positioning block 201j is used to support the pressing plates 201h.

[0039] A first gear 205a is fixed on the outside of the support shaft 201i. One side of the baffle is rotatably connected with a rotating column 205b through a bearing. A second gear 205c is fixed on the outside of the rotating column 205b. The first gear 205a meshes with the second gear 205c. A pulley 205d is fixed on the outside of the rotating column 205b. A pulley 205d is also fixed on the outside of the other support shaft 201i. The two pulleys 205d are connected by a belt drive. Through the cooperation of the above structure, when one support shaft 201i rotates, it can drive the other support shaft 201i to rotate, and the two support shafts 201i rotate in opposite directions. In this way, the two pressing plates 201h can rotate simultaneously and in opposite directions, so as to press both sides of the PVC sheet at the same time.

[0040] When the pressing plate 201h rotates upward and does not block the positioning frame 201a, the cut PVC sheet will fall onto the top of the support plate 201b. At the same time, the pressing plate 201h will rotate downward and press the PVC sheet on the top of the support plate 201b, so as to press a plurality of stacked PVC sheets tightly, thereby avoiding the situation that the PVC sheets are stacked too loosely and are prone to scattering during the packaging process.

[0041] As the number of PVC sheets stacked on the top of the support plate 201b increases, the support plate 201b will be pressed downward and drive the connecting plate 201c to move downward, so that the connecting plate 201c squeezes the first spring 201g. When the support plate 201b moves downward a specified distance and the PVC sheets are stacked in a specified quantity, the support plate 201b will rotate downward and release the support for the PVC sheets, so that the PVC sheets can fall downward, and then they can be packaged. At this time, the first spring 201g pushes the connecting plate 201c and the support plate 201b to move upward to reset the support plate 201b, so as to support the cut PVC sheets again.

[0042] The moving component 300 is arranged below the material receiving component 200 and includes a base 301a, a material receiving box 301b, a connecting block 301c, a movable frame 301d, a positioning plate 301e, a second spring 301f, a connecting sleeve 301g, a connecting column 301h, a threaded plate 301i, and a threaded column 301j. The base 301a is located below the positioning frame 201a, the material receiving box 301b is arranged above the base 301a, the connecting block 301c is fixed to the bottom of the material receiving box 301b, the movable frame 301d is located outside the connecting block 301c. A through groove 301a-1 is formed in the base 301a, and the movable frame 301d is movably connected to the through groove 301a-1. The positioning plate 301e is fixed inside the movable frame 301d, and both ends of the second spring 301f are fixed to the positioning plate 301e and the connecting block 301c respectively. The connecting sleeve 301g is fixed to the bottom of the connecting block 301c, the connecting column 301h is inserted into the connecting sleeve 301g, the threaded plate 301i is fixed to the bottom end of the connecting column 301h, and the threaded column 301j is arranged at the bottom of the base 301a.

[0043] The threaded column 301j is inserted into the movable frame 301d and is movably connected to the inside of the movable frame 301d. The material receiving box 301b is U-shaped and is used to receive the neatly stacked PVC sheets and drive the sheets to move to one side. During the stacking process of the PVC sheets, the woven bag for encapsulating the sheets is laid flat on the top of the material receiving box 301b. When the PVC sheets fall downward, they will land on the top of the woven bag and press the woven bag downward, so that the PVC sheets can be directly seated on the woven bag without manually moving the PVC sheets to the top of the woven bag again.

[0044] Meanwhile, the weight of the PVC sheets will drive the material receiving box 301b to move downward, and drive the connecting block 301c and the connecting sleeve 301g to move downward through the material receiving box 301b, so that the connecting sleeve 301g drives the connecting column 301h and the threaded plate 301i to move downward, and makes the threaded plate 301i engage with the threaded column 301j. When the threaded column 301j rotates, it can drive the movable frame 301d to move through the cooperation of the threaded plate 301i, so that the movable frame 301d drives the material receiving box 301b to move out from below the positioning frame 201a. At this time, the woven bag can be sealed with tape to complete the encapsulation of the PVC sheets.

[0045] Embodiment 2

[0046] Refer to Figures 1 - 11 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0047] Specifically, an activity groove 201d-1 is formed in the fixed shaft 201d. A limit post 202a is arranged in the activity groove 201d-1. A limit hole 201b-1 is formed in the support plate 201b. The limit post 202a is engaged with the limit hole 201b-1.

[0048] When the limit post 202a is engaged with the limit hole 201b-1, the cooperation between the two is used to lock the support plate 201b, so as to avoid the situation that the support plate 201b rotates downward when receiving the weight of the PVC sheet. A sixth spring is fixed on one side of the limit post 202a. The sixth spring is used to apply a thrust to the limit post 202a to make its engagement with the limit hole 201b-1 more firm.

[0049] Specifically, a push rod 202c is inserted into the fixed shaft 201d. A force-receiving groove 202a-1 corresponding to the push rod 202c is formed in the limit post 202a. A push block 202d is fixed inside the positioning frame 201a. The push block 202d is matched with the push rod 202c. A torsion spring 202e is fixed outside the fixed shaft 201d. One end of the torsion spring 202e is fixed to the support plate 201b.

[0050] The inner wall of the force-receiving groove 202a-1 is inclined. One end of the push rod 202c located outside the fixed shaft 201d is inclined. When the PVC sheets stacked on the top of the support plate 201b reach the specified quantity, the push rod 202c will contact the push block 202d. As the push rod 202c moves downward, the push block 202d will squeeze its inclined surface, so as to push the push rod 202c to move, and the inner wall inclined surface of the force-receiving groove 202a-1 is squeezed through the push rod 202c. The cooperation between the two drives the limit post 202a to move, so that the limit post 202a is separated from the limit hole 201b-1, so as to release the restriction on the support plate 201b. Furthermore, the support of the PVC sheet by the support plate 201b can be released, and the PVC sheet can fall downward into the material receiving box 301b.

[0051] When the PVC sheet is separated from the support plate 201b and the support plate 201b moves upward, at this time, the torsion spring 202e will apply a torsional force to the support plate 201b and make the support plate 201b rotate upward to the horizontal state. At this time, the limit post 202a will be engaged with the limit hole 201b-1 again under the thrust of the sixth spring, so as to continue to lock the support plate 201b.

[0052] Specifically, a rotating rod 203a is fixed outside the support shaft 201i. A sliding groove 203a-1 is formed in the rotating rod 203a. A movable shaft 203b slides in the sliding groove 203a-1. A pull rod 203c is fixed outside the movable shaft 203b. A slide rail 203d is fixed at the bottom end of the pull rod 203c. A rotating plate 203e is fixed at the end of the threaded column 301j. A sliding shaft 203f is fixed on one side of the rotating plate 203e. The sliding shaft 203f is movably connected inside the slide rail 203d.

[0053] The rotating rod 203a is inclined. A groove is formed at the center of the pressing plate 201h. The rotating rod 203a is located in the groove. The sliding shaft 203f is fixed at the edge position of the rotating plate 203e. Therefore, when the rotating plate 203e rotates, it will drive the sliding shaft 203f to move inside the slide rail 203d, and drive the pull rod 203c to move up and down through the cooperation of the two. When the pull rod 203c moves downward, it will drive the rotating rod 203a to rotate downward through the cooperation of the movable shaft 203b and the sliding groove 203a-1, and drive the support shaft 201i and the pressing plate 201h to rotate through the rotating rod 203a, so that the pressing plate 201h can rotate upward and separate from the inside of the positioning frame 201a, so that the cut PVC sheet can fall into the positioning frame 201a. When the pull rod 203c moves upward, the pressing plate 201h can be rotated downward, and then the PVC sheet inside the positioning frame 201a can be pressed by the pressing plate 201h.

[0054] The rotation frequency of the pressing plate 201h is the same as the cutting and dropping frequency of the PVC sheet. When the pressing plate 201h rotates to the upper side, the cutting of the PVC sheet is completed at this time, and the PVC sheet will fall into the positioning frame 201a. Therefore, during the rotation of the pressing plate 201h, it will not hinder the normal dropping of the PVC sheet.

[0055] Specifically, a support sleeve 204a is fixed at the bottom of the positioning frame 201a. A support rod 204b is inserted into the support sleeve 204a. A pressing block 204c is fixed at the bottom end of the support rod 204b. A third spring 204d is fixed at the top end of the support rod 204b. The top end of the third spring 204d is fixed to the inner top wall of the support sleeve 204a.

[0056] The number of the support sleeve 204a, the support rod 204b, the pressing block 204c and the third spring 204d is four, which are respectively located at the four corners of the bottom of the positioning frame 201a.

[0057] When the woven bag for encapsulating the PVC sheet is laid flat on the top of the material receiving box 301b, the woven bag can be pressed by the pressing block 204c to prevent the woven bag from moving due to external force, so that the PVC sheet cannot be accurately located on the top of the woven bag. During the encapsulation process, the position of the woven bag needs to be adjusted, which may cause the PVC sheet to be scattered.

[0058] The support sleeve 204a is used to position the support rod 204b, and the third spring 204d is used to apply a downward thrust to the support rod 204b, so that the support rod 204b can drive the pressing block 204c to press and fix the woven bag.

[0059] One side of the material receiving box 301b above and close to the pull rod 203c is inclined. When the material receiving box 301b moves downward below the positioning frame 201a, the pressing block 204c can be pushed upward through its inclined surface, so as not to hinder the reset of the material receiving box 301b.

[0060] Specifically, one side of the support sleeve 204a is rotatably connected to a rotating frame 204e through a rotating shaft. One side of the support sleeve 204a is fixed with a guide shaft 204f. A guide groove 204e-1 is formed on the rotating frame 204e. The guide shaft 204f slides in the guide groove 204e-1, and the guide groove 204e-1 is inclined.

[0061] The rotating frame 204e is U-shaped and there are two of them, respectively located on both sides of the positioning frame 201a. The number of the guide shafts 204f is the same as that of the support sleeves 204a. When the support plate 201b is released from the restriction and rotates downward under the thrust of the PVC sheet, the support plate 201b will contact the rotating frame 204e and push the rotating frame 204e to rotate. When the rotating frame 204e rotates, the guide shaft 204f will move upward along the inclined direction of the guide groove 204e-1, and drive the support rod 204b and the pressing block 204c to move upward, so that the pressing block 204c is separated from the woven bag, thereby releasing the fixation of the woven bag. In this way, when the PVC sheet contacts the woven bag, it can press the woven bag downward and sit on the top of the woven bag.

[0062] When the material receiving box 301b is reset and a woven bag needs to be placed on its top again, only need to pull the rotating frames 204e on both sides outward and move the pressing block 204c upward.

[0063] Embodiment 3

[0064] Refer to Figures 1 - 11 This is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0065] Specifically, an installation plate 302a is fixed to the bottom of the base 301a, and a motor 302b is fixed inside the installation plate 302a. The threaded column 301j is fixed to the output shaft of the motor 302b.

[0066] Through the setting of the motor 302b, it is used to drive the threaded column 301j to rotate.

[0067] Specifically, at the bottom of the base 301a, there is a stabilizing block 303a. On one side of the stabilizing block 303a, a fourth spring 303b is fixed. One end of the fourth spring 303b is fixed to the movable frame 301d and is sleeved outside the threaded column 301j.

[0068] When the movable frame 301d moves, it will stretch the fourth spring 303b. When the PVC sheet in the receiving box 301b is encapsulated and taken away, the second spring 301f can push the connecting block 301c upward, and drive the connecting sleeve 301g and the connecting column 301h upward through the connecting block 301c, so that the connecting column 301h drives the threaded plate 301i to separate from the threaded column 301j, thereby releasing the restriction on the movable frame 301d. At this time, the fourth spring 303b can apply a pulling force to the movable frame 301d, and drive the receiving box 301b to reset through the movable frame 301d.

[0069] Specifically, a fifth spring 304 is fixed to the top end of the connecting column 301h, and the top end of the fifth spring 304 is fixed to the inner wall of the connecting sleeve 301g.

[0070] The connecting column 301h and the connecting sleeve 301g are connected by the fifth spring 304, so that the connecting sleeve 301g can drive the connecting column 301h to move when moving up and down. When the threaded plate 301i meshes with the threaded column 301j, a downward thrust can also be applied to the connecting column 301h and the threaded plate 301i through the fifth spring 304, making the meshing between the threaded plate 301i and the threaded column 301j more firm. At the same time, the connection state between the two is in a flexible connection state. When the movable frame 301d contacts the inner wall end of the through groove 301a-1 and cannot move further, when the threaded column 301j continues to rotate, at this time, when the threaded plate 301i cannot move, it will separate from the threaded column 301j, and thus will not hinder the normal rotation of the threaded column 301j.

[0071] Specifically, it further includes a main body assembly 100, which is connected to the material receiving assembly 200, including a calendering device 101 and a cutting device 102. The cutting device 102 is located on one side of the base 301a, and the calendering device 101 is arranged on one side of the cutting device 102.

[0072] The calendering device 101 is used to extrude and extend plastic materials to make them into continuous sheet-like or film-like products. When the products are formed, they can be cut into required sizes by the cutting device 102. The calendering device 101 and the cutting device 102 are used in cooperation, and a cooling mechanism and multiple guiding and tension rollers are arranged between them. This is the prior art, so it will not be elaborated in this solution. Those skilled in the art can know the working principle and how it is set.

[0073] In summary, the receiving mechanism of the PVC sheet calendering equipment of the present invention has the following advantages:

[0074] First, it can tightly press the stacked PVC sheets one by one, thereby avoiding the situation that the packaged PVC sheets are too loose;

[0075] Second, it can control the quantity of the stacked PVC sheets by itself. When packaging, there is no need to count the quantity of PVC sheets again, and the quantity of packaged PVC sheets can be made consistent;

[0076] Third, it can automatically transfer a specified quantity of stacked PVC sheets, and during the transfer process, the PVC sheets will not be scattered;

[0077] Fourth, during the transfer of PVC sheets, the PVC sheets can be directly placed on the woven bags for packaging;

[0078] Fifth, it can fix the woven bags for packaging to prevent them from shifting during the waiting process.

[0079] During use, when the cutting equipment 102 cuts the formed PVC sheet and the cut PVC sheet falls into the positioning frame 201a, start the motor 302b to drive the threaded column 301j to rotate. Drive the rotating plate 203e to rotate through the threaded column 301j. When the rotating plate 203e rotates, it will drive the sliding shaft 203f to move in the slide rail 203d, and drive the pull rod 203c to move up and down through the cooperation of the two. When the pull rod 203c moves upward, it will drive the rotating rod 203a to rotate upward through the cooperation of the movable shaft 203b and the chute 203a-1, and drive the support shaft 201i and the pressing plate 201h to rotate through the rotating rod 203a, so as to make the pressing plate 201h press the PVC sheet inside the positioning frame 201a.

[0080] As the stacked PVC sheets on the top of the support plate 201b increase, the support plate 201b will be pressed downward, driving the connecting plate 201c to move downward, so that the connecting plate 201c squeezes the first spring 201g. When the support plate 201b moves downward a specified distance and the PVC sheets are stacked in a specified quantity, the push rod 202c will contact the push block 202d. As the push rod 202c moves downward, the push block 202d will squeeze its inclined surface, thereby pushing the push rod 202c to move, and squeezing the inner wall inclined surface of the force receiving groove 202a-1 through the push rod 202c. Drive the limit post 202a to move through the cooperation of the two, so that the limit post 202a is separated from the limit hole 201b-1, thereby releasing the restriction on the support plate 201b, and then the support plate 201b can be released from supporting the PVC sheet, and the PVC sheet will fall downward into the receiving box 301b.

[0081] When the PVC sheet drops downward, it will land on the top of the woven bag and press the woven bag downward, so that the PVC sheet can be directly seated on the woven bag without the need for manual handling of the PVC sheet to the top of the woven bag again.

[0082] Meanwhile, the weight of the PVC sheet will drive the material receiving box 301b to move downward, and drive the connecting block 301c and the connecting sleeve 301g to move downward through the material receiving box 301b, so that the connecting sleeve 301g drives the connecting column 301h and the threaded plate 301i to move downward, and makes the threaded plate 301i engage with the threaded column 301j. When the threaded column 301j rotates, the movable frame 301d can be driven to move through the cooperation of the threaded plate 301i, so that the movable frame 301d drives the material receiving box 301b to move out from below the positioning frame 201a. At this time, the woven bag can be sealed with tape to complete the packaging of the PVC sheet.

[0083] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
