Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, specifically to a feeding compensation device for a fully automatic film coating machine. Background Technology

[0002] The fully automatic packaging box laminating machine is an automated device used for automatically laminating packaging boxes. It primarily covers the surface of packaging boxes with a transparent plastic film to enhance gloss, protect printed patterns, and extend service life. Through hot pressing or pre-coating technology, the transparent plastic film is firmly bonded to the packaging box surface, forming a protective layer of approximately 10-20 micrometers. This is suitable for surface binding and moisture protection of paper packaging such as book covers, brochures, and gift boxes. The machine automatically completes the processes of film application, lamination, and cutting without manual intervention, significantly improving production efficiency.

[0003] The feeding device of the fully automatic laminating machine consists of a lifting platform, a paper separation device, and a conveying device. Traditionally, when feeding, the material needs to be placed on the lifting platform first. The lifting platform lifts the material up so that the material at the top comes into contact with the paper separation device and the conveying device. The paper separation device and the conveying device work together to transport the stacked material to the die-cutting position.

[0004] Although traditional lifting platforms can lift materials to ensure that the gradually decreasing material continues to be in contact with the paper separating and conveying devices, in order to ensure the fit between the material and the conveying devices, the lifting platform needs to lift the material intermittently as the material decreases. This makes it difficult to reduce the lifting frequency of the lifting platform and reduce the energy consumption caused by the frequent start-stop of the lifting platform. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding compensation device for a fully automatic film coating machine, addressing the deficiencies and shortcomings of the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a feeding compensation device for a fully automatic film coating machine, comprising a bearing base plate placed on an external lifting platform for bearing materials, and further comprising a plurality of placement slots equally spaced on the bearing base plate, a plurality of support rods with one end set on the bearing base plate within each placement slot and the other end set outside the placement slot, and a counterweight block set on the other end of each support rod, wherein the length of the support rod is greater than the length of the placement slot, and the support rod is fitted with the placement slot with a clearance.

[0007] A further improvement is that: a connecting groove is provided at the other end of the support rod, and a connecting block is provided on the counterweight block for clearance fitting with the connecting groove. A fixing element is provided between the connecting block and the other end of the support rod in the connecting groove for fixing or releasing the connecting block in the connecting groove after clearance fitting between the connecting block and the connecting groove.

[0008] A further improvement is that the fastener includes a circular groove and a circular block, the connecting groove being a threaded groove, and the connecting block being threadedly connected to the connecting groove.

[0009] A further improvement is that the fixing component includes a locking hole opened at the other end of the support rod and communicating with the connecting groove, a corresponding locking groove opened on the connecting block for corresponding to the locking hole position after the connecting block and the connecting groove are fitted together, a locking block slidably disposed at the other end of the support rod located in the locking hole, and a compression spring disposed at the locking block and the other end of the support rod located in the locking hole for pushing the locking block to engage with the corresponding locking groove after the corresponding locking groove and the locking hole position are aligned.

[0010] A further improvement is that the engaging block has a chamfered surface.

[0011] A further improvement is that the engaging block is a sphere, the support rod has an engaging arc-shaped hole to prevent the engaging block from slipping out of the engaging hole, and the corresponding slot is an arc groove.

[0012] A further improvement is that each of the support rods is provided with an elastic contact layer to reduce the rigid contact between the support rod and the material.

[0013] A further improvement is that the elastic contact layer is a silicone layer or a rubber layer.

[0014] A further improvement is that the support rod is a carbon steel rod plated with hard chrome or a stainless steel rod.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are as follows: the material is first stacked on the upper surface of the supporting base plate, and then the supporting base plate carrying the material is placed on the lifting platform. Each support rod is inserted from each placement slot, so that one end of each support rod is located on the lower surface of the material. The counterweight block is set to make one end of each support rod tilted up in the placement slot and abut against the lower surface of the material. The lifting platform first intermittently lifts the material. When the stacked material is reduced to a certain amount, the pressure of the material on one end of the support rod decreases, and the counterweight block promptly drives the support rod to lift the material. At this time, the material can be continuously pressed against the feeding device without the lifting platform being raised. By subsequently increasing the lifting stroke of the lifting platform, the lifting frequency of the lifting platform is reduced, thereby reducing the energy consumption of the lifting platform due to frequent start and stop.

[0016] Further benefits: The number of slots can be increased, and the number of support rods can be installed as needed. The more support rods and counterweight blocks there are, the better the material support effect, and the more the subsequent lifting stroke of the lifting platform can be increased, thereby reducing the lifting frequency of the lifting platform.

[0017] Further benefits: After the connecting block is inserted into the connecting groove, the locking hole and the corresponding locking groove are aligned. At this time, the compression spring pushes the locking block to engage with the corresponding locking groove, thereby increasing the sliding resistance of the connecting block in the connecting groove and playing a fixing role; when it is necessary to replace the counterweight block of other weights, it can also be disassembled and assembled in a timely manner.

[0018] Further benefits: The chamfered surface allows the connecting block to contact the locking block first when it is pushed into the connecting slot. This causes the locking block to retract into the locking hole due to the push of the chamfered surface. Compared with pushing the locking block in with its right-angled surface, this improves the ease of connection between the connecting block and the connecting slot. Attached Figure Description

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0026] See Figures 1 to 4As shown, the technical solution adopted in this specific embodiment is: a feeding compensation device for a fully automatic film coating machine, including a supporting base plate 1 placed on an external lifting platform for supporting materials, and several placement slots 2 equidistantly opened on the supporting base plate 1; several support rods 3 with one end located in each placement slot 2 on the supporting base plate 1 and the other end located outside the placement slot 2; and a counterweight block 4 disposed on the other end of each support rod 3. The length of the support rod 3 is greater than the length of the placement slot 2, and the support rod 3 and the placement slot 2 are clearance-fitted. The material and weight of the counterweight block 4 are selected according to the required support force for the material.

[0027] The other end of the support rod 3 is provided with a connecting groove 5. The counterweight block 4 is provided with a connecting block 6 for clearance fit with the connecting groove 5. The connecting block 6 and the other end of the support rod 3 are provided with a fixing member in the connecting groove 5 for fixing or unfixing the connecting block 6 in the connecting groove 5 after the connecting block 6 and the connecting groove 5 are clearance fit.

[0028] The fastener includes: the connecting groove 5 and the connecting block 6 are a circular groove and a circular block, the connecting groove 5 is a threaded groove, and the connecting block 6 is threadedly connected to the connecting groove 5.

[0029] The fastener includes a locking hole 7 opened at the other end of the support rod 3 and communicating with the connecting groove 5; a corresponding locking groove 8 opened on the connecting block 6 for corresponding to the position of the locking hole 7 after the connecting block 6 and the connecting groove 5 are in clearance fit; a locking block 9 slidably disposed at the other end of the support rod 3 located in the locking hole 7; and a compression spring 10 disposed at the locking block 9 and the other end of the support rod 3 located in the locking hole 7 for pushing the locking block 9 to engage with the corresponding locking groove 8 after the corresponding locking groove 8 and the locking hole 7 are aligned. When the connecting groove 5 and the connecting block 6 are square, the engaging hole 7 is circular or square, and the number of engaging holes 7 is one or more. The corresponding slot 8 is located at the corresponding position of the connecting block 6 and the engaging hole 7. When the connecting groove 5 and the connecting block 6 are cylindrical, the compression spring 10 and the engaging hole 7 can be omitted. The engaging block 9 is set as an arc block, and the corresponding slot 8 is an arc groove. Fixing is achieved through the cooperation of the protrusion and the groove.

[0030] The locking block 9 has a chamfered surface 11.

[0031] The engaging block 9 is a sphere, and the support rod 3 has an engaging arc-shaped hole 12 to prevent the engaging block 9 from slipping out of the engaging hole 7. The corresponding engaging groove 8 is an arc groove. The engaging block 9 can also be a square block. In order to reduce the friction between the engaging block 9 and the surface of the connecting block 6, the protruding end of the engaging block 9 can be set as an arc surface. When the engaging block 9 is set as a square block, a guide groove can be set to communicate with the engaging hole 7. The side length of the guide groove is greater than the side length of the engaging hole 7. A corresponding engaging block 9 is set on the engaging block 9. The engaging block 9 and the guide groove are in clearance fit. The side length of the engaging block 9 is greater than the engaging hole 7.

[0032] Each of the support rods 3 is provided with an elastic contact layer 13 for reducing the hard contact between the support rod 3 and the material.

[0033] The elastic contact layer 13 is a silicone layer or a rubber layer. Compared with a contact layer made of flexible material, it can provide protection while maintaining elastic contact, and can also effectively transfer the pressure of the support rod 3 lifting onto the material, preventing the contact layer from being too soft and weakening the lifting pressure.

[0034] The support rod 3 is made of carbon steel with hard chrome plating or stainless steel. The support rod 3 is a solid rod. Carbon steel with hard chrome plating has high surface hardness and is not easily deformed. Stainless steel has extremely strong corrosion resistance.

[0035] The working principle of this utility model is as follows: The material is first stacked on the upper surface of the supporting base plate 1, and then the supporting base plate 1 carrying the material is placed on the lifting platform. Each support rod 3 is inserted from the position of each placement slot 2, so that one end of each support rod 3 is located on the lower surface of the material. The counterweight block 4 is set to make one end of each support rod 3 tilt up in the placement slot 2 and abut against the lower surface of the material. The lifting platform first intermittently lifts the material. When the stacked material is reduced to a certain amount, the pressure of the material on one end of the support rod 3 decreases. The counterweight block 4 promptly drives the support rod 3 to lift the material. At this time, the material can be continuously pressed against the feeding device without the lifting platform being raised. By increasing the lifting stroke of the lifting platform in the future, the lifting frequency of the lifting platform is reduced, thereby reducing the energy consumption of the lifting platform due to frequent start and stop.

[0036] The number of slots 2 can be increased, and the number of support rods 3 can be installed as needed. The more support rods 3 and counterweight blocks 44 there are, the better the supporting effect on the material, and the more the subsequent lifting stroke of the lifting platform can be increased, thereby reducing the lifting frequency of the lifting platform.

[0037] After the connecting block 6 is inserted into the connecting groove 5, the position of the engaging hole 7 corresponds to the corresponding engaging groove 8. At this time, the compression spring 10 pushes the engaging block 9 to engage with the corresponding engaging groove 8, thereby increasing the sliding resistance of the connecting block 6 in the connecting groove 5 and playing a fixing role. When it is necessary to replace the counterweight block 4 of other weights, it can also be disassembled and installed in time.

[0038] The chamfered surface 11 is designed so that when the connecting block 6 is pushed into the connecting groove 5, the chamfered surface 11 first contacts the position of the locking block 9, so that the locking block 9 is pushed into the locking hole 7 by the chamfered surface 11. Compared with the right angle surface of the locking block 9 being pushed in, this can improve the connection convenience between the connecting block 6 and the connecting groove 5.
