Description

TECHNICAL FIELD

[0001] The utility model relates to hot cutting technical field, more particularly to a split hot cutting knife mounting bracket and hot cutting device. BACKGROUND

[0002] In prior art, the knife holder for blow-filling-sealing integrated machine is usually made of integrated material, mostly made of brass. The structure design of the existing knife holder is integral type, which cooperates with the hot cutting knife and other components to realize relevant functions. In actual use, the knife holder is installed and cooperated with the moving platform of the equipment as a whole, which is used for cutting and other operations on the plastic material in hot melt state. The moving platform can drive the hot cutting knife to move in multiple directions through the knife holder, so as to move relative to the workpiece to be cut and improve the cutting flexibility. When the hot cutting knife works, its working temperature is generally 600-800 DEG C.

[0003] The inventor found at least the following shortcomings of the integral hot cutting knife mounting bracket in prior art during research:

[0004] Firstly, the processing technology of the knife holder made of integrated material is complex, which needs to process the whole brass material through multiple processing procedures, resulting in high material cost and processing cost. Due to the integrated design, the material utilization rate is low and the processing difficulty is great, and the raw material and labor cost is wasted more in the production process;

[0005] Secondly, when the knife holder made of brass is in high temperature environment (such as the working temperature of the cutting knife of blow-filling-sealing integrated machine is 600-800 DEG C), it is easy to deform when the temperature approaches or exceeds its tolerance limit, which affects the cooperation precision with the hot cutting knife and other components, reduces the cutting quality, and even causes equipment failure, which has adverse effects on production efficiency and product quality.

[0006] Thirdly, when the knife holder and the hot cutting knife need to be disassembled and maintained or replaced, the knife holder made of brass is melted at high temperature due to the high temperature of the working environment, which causes the screw and the knife holder to be bonded and difficult to disassemble. This not only increases the difficulty and time cost of equipment maintenance, but also may damage the knife holder or other components by forced disassembly, further increasing the maintenance cost.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings can be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0032] It should be noted that: similar signs and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0033] In the description of the present application, it should be noted that if the terms "upper", "lower", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship of the product in use, it is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the present application.

[0034] In addition, if the terms "first", "second" and the like appear, they are only used for differentiation in description, and cannot be understood as indicating or implying relative importance.

[0035] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0036] In the prior art, the cutter holder is provided in an integrated structure, which has high manufacturing difficulty, low material utilization rate, and needs to be replaced as a whole when damaged, resulting in high maintenance cost. Moreover, the existing cutter holder is made of brass material, which has poor high-temperature resistance. When the cutter is working, the temperature can reach 600-800℃, which easily causes the cutter holder to be deformed by heat, thereby affecting the accuracy of the cutter position. After the cutter holder is deformed by heat, the screws or other structures at the connection between the cutter and the cutter holder are also affected, resulting in inconvenience in disassembling and assembling the cutter.

[0037] Therefore, the designer provides a split type hot cutter mounting rack, which reduces the manufacturing difficulty, improves the material utilization rate, and reduces the manufacturing cost by setting the cutter holder in a split type structure. Moreover, each part can be replaced individually when damaged, thereby reducing the maintenance cost.

[0038] Please refer to Figs. 1-3 The present embodiment provides a split type hot cutter mounting rack, which comprises a cutter holder body 100, the cutter holder body 100 comprising a detachably connected conductive part 110 and a mounting part 120. The conductive part 110 is used to connect with the cutter body 001, and the mounting part 120 is used to connect with a moving platform (not shown in the figure). The moving platform is used to drive the cutter holder body 100 to move.

[0039] The moving platform can be a two-dimensional moving platform or a three-dimensional moving platform, etc. The two-dimensional moving platform can drive the tool holder body 100 to reciprocate in the first direction and the second direction, and the three-dimensional moving platform can drive the tool holder body 100 to reciprocate in the first direction, the second direction and the third direction. The first direction, the second direction and the third direction are perpendicular to each other unless otherwise specified.

[0040] It should be understood that the two-dimensional moving platform and the three-dimensional moving platform can be set as a mechanical hand, etc.

[0041] As described above, the working mode of the split hot cutter mounting rack of the embodiment is as follows:

[0042] The two tool holder bodies 100 cooperate to position both ends of the cutter body 001, that is, the two ends of the cutter body 001 are fixedly connected with the conductive parts 110 of the two tool holder bodies 100 respectively. The two tool holder bodies 100 are connected with the moving platform. The moving platform can drive the cutter body 001 to move relative to the workpiece through the tool holder body 100, so as to perform flexible cutting action. It should be understood that since the tool holder body 100 is set as a split structure, the conductive part 110 and the mounting part 120 are independent of each other, and they are independently manufactured, which greatly improves the utilization rate of materials, reduces the processing difficulty and reduces the processing manufacturing cost. At the same time, the conductive part 110 and the mounting part 120 can be replaced independently, and the maintenance and repair cost is low.

[0043] The following embodiments illustrate the details of the split hot cutter mounting rack of the present application by way of example.

[0044] Please refer to Figs. 1-3 In the embodiment, the split hot cutter mounting rack can optionally include a tool holder body 100, the tool holder body 100 including a conductive part 110, a mounting part 120, a fastener 130 and a positioning part 140. The conductive part 110 and the mounting part 120 are detachably connected through the fastener 130. The conductive part 110 cooperates with the positioning part 140 to clamp and position the cutter body 001. The mounting part 120 is used to connect with the moving platform.

[0045] By setting the tool holder body 100 as a split structure, it is convenient for processing and manufacturing, and the maintenance and repair cost is low.

[0046] In the embodiment, the conductive part 110 can optionally include a one-piece plate body 111 and a reinforcing strip 112. The reinforcing strip 112 can increase the strength of the plate body 111, so that the plate body 111 is not easy to deform, and the stability and reliability are improved.

[0047] Optionally, the plate body 111 has opposite first and second plate surfaces, and the reinforcing strip 112 is arranged on the first plate surface and aligned with a side edge of the plate body 111. The second plate surface is used to abut against the cutter body 001 to position the cutter body 001.

[0048] Please refer to Figs. 1-3 Further, the plate body 111 is provided with a first fixing hole 1111, a second fixing hole 1112, and a third fixing hole 1113. The number of the first fixing hole 1111, the second fixing hole 1112, and the third fixing hole 1113 can be multiple and arranged at intervals. The first fixing hole 1111, the second fixing hole 1112, and the third fixing hole 1113 all penetrate the first and second plate surfaces, and at the same time, the first fixing hole 1111 penetrates the reinforcing strip 112. The first fixing hole 1111, the second fixing hole 1112, and the third fixing hole 1113 can all be circular holes, and the axes of the first fixing hole 1111, the second fixing hole 1112, and the third fixing hole 1113 can be arranged in parallel. Among them, the second fixing hole 1112 and the third fixing hole 1113 can be arranged as threaded holes.

[0049] It should be understood that the conductive part 110, i.e., the plate body 111 and the reinforcing strip 112, can be made of a high-temperature-resistant conductive material, for example, the conductive part 110 can be made of tungsten-copper alloy material, etc. The conductive part 110 can remain structurally stable even in a high-temperature environment of 1000°C. In this way, when the conductive part 110 is energized and transmits current to the cutter body 001, and the cutter body 001 is used for cutting, the heat of the cutter body 001 is transferred to the conductive part 110. The conductive part 110 has stable structure, small thermal expansion coefficient, and good dimensional stability when the temperature changes, which ensures the cutting precision and normal operation of the equipment. At the same time, when disassembling the cutter holder body 100 or the cutter body 001, the tungsten-copper alloy material can effectively avoid the situation that the screws cannot be disassembled due to high-temperature melting, facilitating equipment maintenance and component replacement.

[0050] In addition, in some embodiments, the plate body 111 and the reinforcing strip 112 can also be fixedly connected together in other ways.

[0051] Please refer to Figs. 1-3 In the present embodiment, the mounting part 120 is optionally arranged in a plate-like structure, and the mounting part 120 is provided with a first assembly hole 121 and a second assembly hole 122. The number of the first assembly hole 121 is equal to the number of the first fixing hole 1111, and the first assembly hole 121 can be a threaded hole. The number of the second assembly hole 122 can be multiple, and the multiple second assembly holes 122 can be circular holes and arranged in parallel. The second assembly hole 122 penetrates the mounting part 120 in the thickness direction of the mounting part 120. The axes of the first assembly hole 121 and the second assembly hole 122 are perpendicular to each other.

[0052] It should be understood that the mounting piece 120 can be made of tungsten-copper alloy material, which has strong high-temperature deformation resistance.

[0053] It is worth noting that when the conductive piece 110 is installed with the mounting piece 120, the mounting piece 120 is attached to the reinforcing strip 112, the first fixing hole 1111 is aligned with the first assembly hole 121, and the fastener 130 is arranged in the first fixing hole 1111 and is screwed with the first assembly hole 121. In this way, the fastener 130 can be a screw, a bolt, etc.

[0054] Alternatively, in other embodiments, the fastener 130 can also be a pin shaft, a rivet, etc., and the pin shaft is arranged in the first fixing hole 1111 and the first assembly hole 121 at the same time. The rivet can realize the riveting cooperation of the conductive piece 110 and the mounting piece 120.

[0055] In addition, in some embodiments, the conductive piece 110 and the mounting piece 120 can also be detachably connected by using a buckle structure, etc.

[0056] Please refer to Figs. 1-3 In the embodiment, optionally, the positioning piece 140 can be a positioning plate, and the positioning piece 140 can be made of tungsten-copper alloy material. The positioning piece 140 is provided with fourth fixing holes 141, the number of the fourth fixing holes 141 is equal to the number of the second fixing holes 1112, and screws can be arranged in the fourth fixing holes 141. The screws are screwed with the second fixing holes 1112 to fix the positioning piece 140 on the second plate surface of the plate body 111. In this way, the cutter body 001 can be clamped and positioned by cooperation of the positioning piece 140 and the plate body 111.

[0057] In order to improve the stability of the installation position of the cutter body 001, a positioning groove 142 can be arranged on the positioning piece 140, and the fourth fixing holes 141 are located around the positioning groove 142, and the cutter body 001 is embedded in the positioning groove 142.

[0058] It should be understood that the split type hot cutter mounting rack provided in the embodiment has a split type structure design, which reduces the processing difficulty, improves the material utilization rate, and reduces the processing and manufacturing cost. Moreover, it is convenient to replace independently when damaged, and the cost is low. At the same time, it is made of tungsten-copper alloy material, which has strong high-temperature resistance and is not easy to deform due to high temperature generated during work of the cutter body 001. It has high stability, the position of the cutter body 001 is accurate and reliable, and it is also convenient for subsequent disassembly.

[0059] The hot cutting device also comprises two split hot cutting knife mounting racks mentioned in the above embodiments, and two conductive parts 110 of the two split hot cutting knife mounting racks are matched with two ends of the cutting knife body 001 respectively.
